A total of six treatments, including continuous conventional tillage (CT), rotary tillage (RT), subsoiling (ST), no-tillage (NT), conventional-no tillage (CT-NT) and subsoiling-no tillage (ST-NT), were conducted to examine the effects of different tillage types on soil aggregates distribution and stability of irrigated sierozem on continuous 8-year-tillage maize fields in the Gansu Yellow River irrigated area in 2014-2017. The results showed that the aggregation and stability of large aggregates in 0-40 cm soil layer were increased by NT and ST-NT treatments, while the size distribution and stability in plough layer were significantly decreased by CT and RT treatments due to strong soil disturbance. Compared with RT, the mechanical stability of aggregates under dry sieving NT was the best. The contents of >0.25 mm aggregate (R 0.25 ), mean weight diameter (MWD) and geometric mean diameter (GMD) increased by 5.8%, 8.0%, and 13.0%, respectively, and fractal dimension (D) decreased by 3.6%. The water-stable aggregates in ST-NT was the best, with R 0.25 , MWD and GMD increased by 55.3%, 15.1% and 8.7%, respectively, and D value decreased by 0.8%. The percentage of aggregate destruction (PAD) and unstable aggregate index (E LT ) of NT and ST-NT treatments were the lowest. PAD was reduced by 5.9% and 7.7% compared with RT, E LT was reduced by 5.8% and 7.2%, respectively. All the results indicated that the subsoiling-notillage (ST-NT) rotation mode was more conducive to the enhancement of soil aggregate content and stability and consistent with the local farmers operating habits, which would be an ideal tillage method and had certain application value for the sustainable agricultural development in this area.

Objective: MicroRNA-26a (miR-26a) exhibits diverse functions in different human disease. However, further research is needed to investigate the potential role of miR-26a in cerebral ischemia injury., Materials and Methods: The expressions of miR-26a and PTEN (phosphatase and tensin homolog) were detected via Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) assay. The protein expression of Bcl-2 and Bax was detected by Western blot assay. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used to observe the cell viability of SH-SY5Y cells. The relationship between miR-26a and PTEN was confirmed by Dual-Luciferase assay and human SH-SY5Y cells were treated with oxygen-glucose deprivation (OGD)/reperfusion to mimic I/R injury., Results: The expression of miR-26a was increased in the OGDR model. Moreover, upregulation of miR-26a promoted cell viability and inhibited OGDR-induced apoptosis. PTEN was confirmed as a direct target gene for miR-26a. Under OGDR conditions, the expression of PTEN was significantly decreased. Moreover, overexpression of PTEN inhibited cell viability, promoted cell apoptosis and deepened the effect of the OGDR model., Conclusions: MiR-26a promoted the viability of SH-SY5Y cells and suppressed apoptosis under OGDR conditions by targeting PTEN.

Objective: This study aimed to explore the effect of perfluorooctanoate acid (PFOA) on the proliferation, migration and invasion of the human muscle rhabdomyosarcoma RD cell line and its related mechanisms. Methods: RD cells were cultured and exposed to PFOA of different concentrations with 6-72 hours. The cell viability was assessed by cell counting kit-8 (CCK-8) assay. Wound healing and transwell filter assay were used to evaluated the migration and invasion ability of the RD cells respectively. The cell cycles were detected by Flow cytometry. Quantitative real-time PCR and Western blot were used to quantify the mRNA and protein expression difference of related genes, respectively. Results: CCK-8 assay showed that, after treated the RD cell with different dose of PFOA for 72 h, low dose PFOA (1,10,50, 100 μmol/L) promotes the proliferation of RD cells while high dose PFOA (250, 500 mol/L) inhibits the proliferation ( P< 0.001). Flow cytometry showed that compared with the control group, there was no significant difference in G0/G1 phase, while cells in S phase deceased and G2/M phase cells increased after treated with PFOA (50 μmol/L) for 72 h. The relative proportions of S and G2/M were significantly different between the two groups ( P< 0.01). The results of qPCR showed that the mRNA relative expression of CDK2 of the control group and the PFOA (50 μmol/L) group were 0.97±0.07 and 2.64±0.11 respectively, and there was a significant difference ( t= 12.60, P< 0.001); The mRNA relative expression of cyclin E2 of the control group and the PFOA (50 μmol/L) group were 1.33±0.17 and 3.35±0.22 respectively, and there was a significant difference ( t= 7.42, P< 0.001); The results of Western blot showed that the protein relative expression of CDK2 of the control group and the PFOA (50 μmol/L) group were 0.35±0.01 and 0.84±0.03 respectively, and there was a significant difference ( t= 14.60, P< 0.001); The protein relative expression of cyclin E2 of the control group and the PFOA (50 μmol/L) group were 0.67±0.04 and 0.86±0.01 respectively, and there was a significant difference ( t= 4.88, P< 0.01); There was no significant difference in the mRNA and protein expression of p21 and p53 between the PFOA and control group ( P> 0.05). The wound healing rate of the PFOA (50 μmol/L) group was faster than that of the control group, and the relative migration area of the PFOA group was larger accordingly ( P< 0.001). After PFOA (50 μmol/L) treated, the number of the cell through the membranes was much more than the control group ( t= 54.40, P< 0.001), which means PFOA significantly stimulated the invasion ability of the RD cells. The results of qPCR showed that the mRNA relative expression of vimentin of the control group and the PFOA (50 μmol/L) group were 0.71±0.03 and 2.53±0.16 respectively, and there was a significant difference ( t= 11.00, P< 0.001); The mRNA relative expression of MMP2 of the control group and the PFOA (50 μmol/L) group were 1.09±0.04 and 10.73±1.20 respectively, and there was a significant difference ( t= 8.04, P< 0.001). The results of Western blot showed that the protein relative expression of vimentin of the control group and the PFOA (50 μmol/L) group were 0.55±0.06 and 0.81±0.01 respectively, and there was a significant difference ( t= 4.50, P< 0.05). The protein relative expression of cyclin E2 of the control group and the PFOA (50 μmol/L) group were 0.64±0.04 and 1.03±0.13 respectively, and there was a significant difference ( t= 2.94, P< 0.05). Conclusions: Low dose PFOA (50 μmol/L) exposure promotes cell proliferation, migration and invasion in the human muscle rhabdomyosarcoma cell line through inducing the expressions of MMP2, vimentin and cell cycle related genes.

Bile acids serve a critical role in the induction of gastric intestinal metaplasia (IM) and gastric carcinogenesis. The present study investigated the effects of bile acids on the induction of gastric IM formation. The results demonstrated that the expression levels of caudal‑related homeobox transcription factor 2 (CDX2), mucin 2 (MUC2) and farnesoid X receptor (FXR) were increased in vitro and in vivo following treatment with bile acids, and CDX2 transcriptionally activated MUC2 expression. Furthermore, knockdown of FXR attenuated bile acid‑enhanced CDX2 promoter activity and protein expression. Conversely, the FXR agonist GW4064 synergistically enhanced bile acid‑induced CDX2 promoter activity. Bile acid treatment led to an increase in nuclear factor (NF)‑κB activity and protein expression. Treatment with GW4064 or the FXR antagonist Z‑guggulsterone enhanced or attenuated bile acid‑induced NF‑κB activity, respectively. In addition, quantitative chromatin immunoprecipitation confirmed that bile acids led to enhanced binding of p50 to the CDX2 promoter, whereas this effect was not observed for p65. Treatment with GW4064 or Z‑guggulsterone enhanced and attenuated the binding activity of p50 to the CDX2 promoter, respectively. These results indicated that bile acids may activate the FXR/NF‑κB signalling pathway, thereby upregulating CDX2 and MUC2 expression in normal gastric epithelial cells.

Root nodules in peanut (Arachis hypogaea L.) could directly utilize nitrogen (N) in the atmosphere as N source, which plays an important role in the N supply in peanut. However, little is known about the mechanism of efficient N fixation by root nodule. In this study, 15 N tracer technology was used to investigate the characteristics of N fixation by root nodule and its relationship with peanut yields of 19 varieties in a pot culture experiment. Results showed that there were significant differences in nodule number, fresh quality, internal material, N fixation amount and other related indices among different varieties. The range of number and fresh mass of root nodule was 170.59-696.15 per pot and 0.83-3.74 g per pot, with coefficients of variation (CV) of 36.1% and 41.1%, respectively. The range of leghaemoglobin content and nitrogenase activity was 15.51-23.23 mg per pot and 2.75-20.46 μmol C 2 H 4 ·h -1 per pot, with CV of 13.1% and 57.2%, respectively. The CV of nitrogenase activity was significantly higher than that of leghaemoglobin content, indicating that nitrogenase activity was not only affected by leghaemoglobin content but also other factors. The range of N fixation by root nodule and total N accumulation was 0.71-1.82 and 2.16-3.72 g per pot, with CV of 21.6% and 12.9%, respectively. The CV of the former was significantly higher than that of the latter, indicating that other N sources could automatically compensate the deficit when N fixation of root nodule was insufficient. Nitrogen fixation by root nodule was one of the main N sources for peanut, while the average N supply percentage was more than 40% of the total N, with a maximum of 50%. Cultivating the variety with high N supply capacity is an effective way for N-saving cultivation in the peanut production. Except for nodule number, there were significantly positive correlations between the other indices and peanut yield, indicating that the physiological indicators of N fixation were closely related to N fixation capacity by root nodule and the final yield. Therefore, enhancing these characters would help achieve high yield of peanut and simultaneously reduce fertilizer application.

Objectives:: To evaluate the effect of laterality, gender, age and body mass index (BMI) on fat fraction (FF) measurements of both parotid glands (PGs) and submandibular glands (SMGs) by using: Iterative decomposition of water and fat with echo asymmetry and least-squares estimation method (IDEAL-IQ)., Methods:: A total of 87 healthy participants were enrolled in our study. IDEAL-IQ image was scanned using a 3.0 T scanner. Paired t test was performed to compare the difference on FF of both PGs and SMGs between left and right side. The FF of two glands between male and female healthy participants were compared using an unpaired t-test. The correlation between the FF of two glands and participant age or BMI were analyzed by Pearson's correlation., Results:: Excellent inter- and intrareader agreements were obtained during the measurements of FF by IDEAL-IQ method (ICC, 0.952-0.981). FF values correlated positively with the age and BMI in both left and right PGs and SMGs (p < 0.05). No significant difference was found on FF between left and right PGs and SMGs (p > 0.05). There was also no difference on FF between male and female healthy participants (p > 0.05)., Conclusions:: FFs of PGs and SMGs were age- and BMI- dependent, but not laterality- and gender-dependent. The effect of age and BMI need to be considered in further studies using Ideal-IQ technology to evaluate FFs of salivary gland diseases.

Background: Our study investigated the demographic characteristics of Mayo Clinic Colon and Rectal Cancer Registry patients and sought to associate tumor location with overall survival. Methods: Using the cohort of patients seen at Mayo Clinic (Minnesota, Arizona, Florida) from 1972 to 2017, we obtained 26,908 colorectal adenocarcinoma patient records. Overall survival of patients with colorectal cancer was analyzed by sidedness (right vs. left) and location (right vs. left vs. rectum). Kaplan-Meier method was used to analyze all demographic and cancer variables available within the dataset to trace survival over a 35-year period. Subgroups within variables were compared to each other using log-rank test and considered significantly different at P < 0.05. Cox proportional hazards regression model was used to assess impact of tumor location while controlling for age, year of diagnosis, sex, tumor stage, and tumor grade. Cox regression models were used to evaluate the independent effect of cancer location on overall survival after adjusting for age, gender, year of diagnosis, and cancer stage. To further explore the potential interaction effect of cancer location with cancer stage and year of diagnosis, similar multivariable Cox model was fit stratified by cancer stage (1-3 vs. 4) and by year of diagnosis (<1980, 1980-2000, >2000). Results: Overall survival differed significantly within all variables studied after Kaplan-Meier method analysis ( P < 0.0001). Survival was higher in the left-side group when evaluated by tumor sidedness, and rectal cancer patients had the highest median survival (101.3 months). Right-sided cancer patients had the worst prognosis in both tumor location and sidedness analyses, with a median survival of 76.6 months. However, the stratified analysis showed that, the difference in survival between left- and right-sided cancer only existed in late cancer stage (stage 4) patients but not in early cancer stage; therefore, screening for CRC to pick cancer at an early stage can influence overall survival significantly. Conclusion: These observations confirm some of the previous and recent studies on sidedness of colorectal cancer patients. Our analysis is novel in that it included patients of all stages rather than just stage IV metastatic patients. This initial study provides a platform to investigate more biologic and clinical factors associated with tumor location. Merging this dataset with other available datasets and previously conducted studies within the institution will provide a robust platform for multiple future studies and collaborations. Finally, appropriate screening can result in a decrease in incidence and mortality of CRC.

Background: Grafting vessel with LIMA to the left anterior descending coronary artery plays a most important role in the long-term prognosis of OPCABG surgery. The aim of this study was to compare the effects of isoflurane preconditioning on miRs and mRNAs levels in the left internal mammary arterie (LIMA) graft with propofol in patients undergoing off-pump coronary artery bypass surgery (OPCABG)., Methods: Patients were randomly assigned to receive either propofol (n = 15), or interrupted isoflurane (n = 15). In group P, propofol administration was continued at 3-5 mg/kg/h intravenous injection for the duration of surgery. Five minutes prior to incision, patients of the isoflurane group (group Iso) received 2 cycles of 1 MAC isoflurane., Results: miR-221 were significantly lower in group Iso (P < 0 .05). E-selectin mRNA, RhoA mRNA and ROK mRNA were significantly lower at specimens of LIMA in group Iso compared with those in group P patients (P < 0 .05). The expression of NOS3 mRNA was significantly higher in group Iso patients (P < 0 .05)., Conclusion: Our findings provide some insight that prior interrupted isoflurane administration could regulate miR-221, and downstream effectors (mRNAs) and resulted in actual attenuation of inflammation and spasm of LIMA in patients undergoing OPCABG surgery., Trial Registration: NCT No. ( ClinicalTrials.gov ): NCT02678650; Registration date: January 23, 2016.

A field experiment was conducted to examine the effects of subsoiling 35 cm with maize straw returning, subsoiling 35 cm without maize straw returning, and rotary tillage without maize straw returning on soil compaction, soil bulk density, soil infiltration, soil water content in 0-100 cm depth, nutrients uptake and production of maize on sierozem in the Gansu Yellow River irrigated area in 2015-2017. Compared with subsoiling 35 cm without maize straw returning and rotary tillage without maize straw returning, subsoiling 35 cm with maize straw returning significantly decreased the soil compaction and soil density in 0-40 cm depth. Compared with that in 2015 (before experiment), soil compaction and soil bulk density in subsoiling 35 cm with straw returning was decreased by 42.6% and 7.0%, respectively, after harvest in 2017. Compared with other treatments, subsoiling 35 cm with straw returning had the lowest variation of soil compaction (6.1%) and soil bulk density (3.2%) in 0-40 cm depth before sowing and after harvest in 2016 and 2017. The soil infiltration rate in subsoiling 35 cm with straw returning was significantly improved by 33.6% compared with rotary tillage without maize straw returning. Subsoiling 35 cm with straw retention could significantly increase soil water content and decrease water variation in 0-100 cm soil depth in spring (before maize sowing) and autumn (after maize harvest). Compared with rotary tillage without maize straw returning, water storage in subsoiling 35 cm with straw retention was increased by 15.5% and 5.6% in spring and autumn, respectively. The water use efficiency was enhanced by 32.4%. Furthermore, subsoiling 35 cm with straw retention could increase maize economic yield and biomass yield by 25.6% and 33.3%, compared with rotary tillage without straw retention. Subsoilng and straw retention could promote nutrient absorption, with N, P 2 O 5 and K 2 O uptake increased by 49.6%, 51.5% and 37.6%, compared with rotary tillage. Overall, our results suggested that subsoiling 35 cm straw retention could improve soil characteristics, stabilize the phy-sical properties of the plough layer, increase soil water content in the 0-100 cm soil layer, and reduce water variation in spring and autumn. Consequently, it was the best management to promote the water and nutrient utilization of maize and achieve high yield. Our findings could provide theoretical basis for further research on the construction technology of the plough layer in Gansu irrigation area.

Background: Astaxanthin (AST) shows a large range of beneficial effects together with anti-cancer and antioxidation properties. Human Serum Albumin (HSA) is the most abundant protein in blood plasma which plays the role of a depot and transport protein for many exogenous compounds. However, whether HSA could enhance AST-induced cytotoxic effects in human ovarian cancer cells has not been examined to date., Objective: This study aims to explore the anticancer effect and the molecular mechanism of AST combine with HSA induced cytotoxicity in ovarian cancer SKOV3 cells., Methods: The ovarian cancer SKOV3 cells were treated by AST combined with HSA to study the effects of cell proliferation, cell morphology, cell cycle arrest, related protein expression, nuclear transfer, cell migration, and drug-resistant., Results: Our data confirmed that AST+HSA treatment enhanced the anticancer effects of AST, arrested G1 phase cell cycle and induced apoptosis in SKOV3 cells. AST+HSA induced apoptosis via mitochondrial apoptotic pathways was related to the increased ratio of Bcl-2/Bax and activation of caspase-3. Besides, exposure of cells to AST+HSA triggered the inactivation of NF-κB and activation p53 and MAPKs signaling pathways. Furthermore, AST+HSA significantly overcome the drug-resistant and inhibited the migration of SKOV3 cells., Conclusion: AST combined treatment with HSA considerably inhibited NF-κB expression and translocation to nucleus, thereby improving the AST-induced cytotoxic effect on SKOV3 cells. These findings may provide rationale to combine AST with HSA for the treatment of ovarian cancer., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Two new species of reticulated beetles (Cupedidae) are described: Tenomerga angulinota sp. nov. from Laos and T. helii sp. nov. from Sichuan, China. Important morphological characters of both new species are illustrated. T. angulinota sp. nov. can be easily recognized from all other Palaearctic-Oriental species by bifid anterior angles of pronotum; T. helii sp. nov. is in habitus very similar to widespread T. anguliscutis (Kolbe, 1886) and can be distinguished based on shape of pronotum, colour pattern of elytra and predominantly male genitalia. In addition, T. anguliscutis is for the first time recorded from Hainan and Jiangxi Provinces of China.

Specimen were bone marrow cells., Results: FISH detection showed that 68 cases of MM (79.07%) had at least one type of the molecular genetic abnormalities. The positive rates of IgH rearrangement, 1q21 amplification, D13S319 deletion, RB1 deletion and.P53 deletion were 62.79%, 26.74%, 24.42% ,13.95% and 1.16%, respectively. The positive rate of IgH was significantly higher than that of any other probes(P<0.01). The positive rate of IgH was 79.41% in 68 cases. Out of which the positive rate of IgH single and combined with 1, 2, 3, 4 probes was 59.26%, 24.07%, 11.11%, 5.56% and 0 respectively. The positive rate of IgH only was very signficantly higher than that of combined with any other probes(P<0.01).The positive rate of 1q21 was 33.82% in 68 cases, Out of which the positive rates of 1q21 or combined with 1,2,3,4 probes was 21.74%, 43.48%, 21.74%,13.04% and 0 respectively, the 1q21 probe showed positive as combined with other probes(P<0.01), especially with IgH(P<0.05). The positive rates of D13S319 were 30.88% in 68 cases of patients, out of which the positive rates of D13S319 single or combined with 1, 2, 3, 4 probes was 14.29%, 28.57%, 42.86%, 14.29% and 0 respectively, the D13S319 combined with other probes appeared more significant positive(P<0.01), especially with 1 or 2 probes (P< 0.01). The positive rate of RB1 was 17.65% in 68 cases, the positive rate of RB1 singl or combined with 1, 2, 3, 4 probes were 0, 25%, 50%, 25% and 0, the RB1 appeared positive always combined with other probes, especially with D13S319 probe (P<0.01). The positive rate of P53 was 1.47%, as combined with RB1 and D13S319 probes. The chromosomal karyotyping showed that 3 cases carried abnormal chromosomal and 17 cases carried normal chromosome, Out of which 17 cases showed positive by FISH. There was a significant difference of sensitivity between FISH combined with chromosome karvotyping and single chromosome karvotype (P< 0.01)., Conclusion: The genetic abnormalies display obvious heterogenicity in MM. The sensitivity of FISH is higher than that of chromosomal karvotyping. If FISH and chromosome karvotyping are combined, the positive rate of abnormality can be raised.

Objective: To evaluate the efficacy of autologous peripheral blood hematopoietic stem cell transplantation (auto-PBHSCT) on patients with multiple myeloma( MM) after Sequential different chemotherapy., Methods: Seven cases of patients with MM were included in the A group, and 14 cases of patients received 4-6 courses of chemotherapy with VAD and MP before transplantation were included in the B group and received 4-6 courses of chemotherapy with VTD and VD before transplantation. Auto-peripheral blood hematopoietic stem cell were mobilized by G-CSF. Condition regimen were melphalan(A group) or bortezomib combined melphalan(B group).

In China, a rapid expansion of hand, foot, and mouth disease (HFMD) outbreaks has occurred since 2004, and HFMD has become an important issue in China. There are more than 20 types of enterovirus causing HFMD, of which coxsackievirus A16 (CA16) and enterovirus 71 (EV71) are the most common. This study aimed to analyze the epidemiological characteristics of HFMD caused by EV71 and CA16 in Linyi, Shandong province, China, from 2009 to 2017. The stool specimens and throat samples of 5,324 patients with HFMD were obtained for nucleic acid detection of enterovirus. A total of 4,040 HFMD cases were caused by viral pathogens. Of these, 1,706 cases were positive for EV71 and 1,266 were positive for CA16. These 2 virus strains appeared alternately in Linyi city. The incidence of EV71-positive and CA16-positive cases was highest in children aged 0-5 years, with male patients being predominant. This outbreak of HMFD caused by EV71 and CA16 mainly occurred between April and July and appeared alternately between the years 2011 and 2017. These results demonstrated that the epidemiological analysis of EV71 and CA16 can provide a scientific basis for the prevention and treatment of the disease.

Objective: To study the correlation between the BRAF V600E mutation and the clinicopathological features of papillary thyroid carcinoma(PTC), and to explore the application value of BRAF V600E mutation in PTC. Method: The BRAF V600E gene mutation was detected in 108 PTC cases and 30 control cases by qPCR. The results were statistically analyzed by using SPSS 21.0 software. Result: The BRAF V600E mutation was absent in the control group. The BRAF V600E mutation rate was 72.20% in 108 PTC cases. Compared with patients with wild type,the mean age of patients with the mutant BRAF V600E was significantly older( P <0.05). BRAF V600E mutations were associated with PTC tissue subtypes and central area lymph node metastasis( P <0.05). BRAF V600E mutations were not correlated with tumor diameter, patient gender, multifocality, tumor site, concomitant disease, lymph node metastasis in side region of neck, capsule invasion, and TNM staging( P >0.05). Conclusion: The value of BRAF V600E mutation in the prognosis of PTC remains to be studied. BRAF V600E mutation is of value for pathological diagnosis of PTC., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)

Previous studies have shown that the incidence of diabetes mellitus (DM) has increased in human immunodeficiency virus (HIV)-infected patients with long-term exposure to highly active antiretroviral therapy (HAART). However, the factors associated with DM among HIV-infected patients in Asia remain unclear in the HAART era.A nationwide cohort studyData from Taiwan's National Health Insurance Research Database (NHIRD) between 2000 and 2010 were used to investigate the incidence of and factors associated with DM among HIV-infected patients. Propensity score matching was conducted to match 4797 patients receiving HAART (HAART cohort) with 4797 patients not receiving HAART (non-HAART cohort). HAART use was treated as a time-dependent variable in a Cox regression model.HAART cohort had a significantly higher 10-year incidence of DM (7.16%; 95% confidence interval [CI], 4.30%-10.03%) than non-HAART cohort (2.24%; 95% CI, 1.28%-3.20%) (P < .001). After adjusting for age, gender, and comorbidities, receiving HAART was associated with an increased incidence of DM, with a subdistribution hazard ratio (sHR) of 2.39 (95% CI, 1.65-3.45). Hypertension (sHR = 5.27; 95% CI, 3.21-8.65), gout (sHR = 2.39; 95% CI, 1.38-4.16), and hepatitis C virus (HCV) infection (sHR = 2.43; 95% CI, 1.28-4.61) were significantly associated with a higher risk of DM. Sensitivity analyses showed exposure to HAART remained significantly associated with an increased risk of DM, particularly in those without pre-existing hypertension, gout, or HCV infection.Exposure to HAART increased the risk of DM in HIV-infected Taiwanese patients, particularly in those without pre-existing hypertension, gout, or HCV infection.

Purpose: The aim of this study was to investigate the value of quantitative DCE-MRI parameters for predicting the immediate non-perfused volume ratio (NPVR) of HIFU therapy in the treatment of symptomatic uterine fibroids., Materials and Methods: A total of 78 symptomatic uterine fibroids in 65 female patients were treated with US-HIFU therapy. All patients underwent conventional MRI and DCE-MRI scans 1 day before and 3 days after HIFU treatment. Permeability parameters K trans , K ep , V e , and V p and T1 perfusion parameters BF and BV of pretreatment were measured as a baseline, while NPVR was used to assess immediate ablation efficiency. Data were assigned to NPVR ≧ 70% and NPVR < 70% groups. Then, the predictive performances of different parameters for ablation efficacy were studied to seek the optimal cut-off value, and the length of time to calculate the variable parameters in each case was recorded., Results: (1) It was observed that the pretreatment K trans , K ep , V e , and BF values of the NPVR ≧ 70% group were significantly lower compared to the NPVR < 70% group (p < 0.05). (2) The immediate NPVR was negatively correlated with the K trans , BF, and BV values before HIFU treatment (r = - 0.561, - 0.712, and - 0.528, respectively, p < 0.05 for all). (3) The AUCs of pretreatment K trans , BF, BV values, and K trans combined with BF used to predict the immediate NPVR were 0.810, 0.909, 0.795, and 0.922, respectively (p < 0.05 for all). (4) The mean time to calculate the variable parameters in each case was 7.5 min., Conclusion: Higher K trans , BF, and BV values at baseline DCE-MRI suggested a poor ablation efficacy of HIFU therapy for symptomatic uterine fibroids, while the pretreatment DCE-MRI parameters could be useful biomarkers for predicting the ablation efficacy in select cases. The software used to calculate DCE-MRI parameters was simpler, quicker, and easier to incorporate into clinical practice.

Background/objective: Degenerative diseases of the lumbar spine were managed with discectomy or laminectomy. This study aimed to compare these two surgical treatments in the postoperative revision rates., Design: A population-based cohort study from analysis of a healthcare database., Setting: Data were gathered from the Taiwan National Health Insurance Research Database (NHIRD)., Participants: We enrolled 16 048 patients (4450 women and 11 598 men) with a mean age of 40.34 years who underwent lumbar discectomy or laminectomy for the first time between 1 January 1997 and 31 December 2007. All patients were followed up for 5 years or until death., Results: Revision rate within 3 months of the index surgery was significantly higher in patients who underwent discectomy (2.75%) than in those who underwent laminectomy (1.18%; p<0.0001). This difference persisted over the first year following the index surgery (3.38% vs 2.57%). One year afterwards, the revision rates were similar between the discectomy (9.75%) and laminectomy (9.69%) groups. The final spinal fusion surgery rates were also similar between the groups (11.25% vs 12.08%)., Conclusion: The revision rate after lumbar discectomy was higher than that after laminectomy within 1 year of the index surgery. However, differences were not identified between patient groups for the two procedures with respect to long-term revision rates and the proportion of patients who required final spinal fusion surgery., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2018.

This article reports a female type Ⅱ Lynch syndrome patient who suffered from colon cancer and endometrium carcinoma consecutively. We also briefly elucidate the pathogenesis,clinicopathological features,screening,and management of Lynch syndrome. Regular screening and early diagnosis and treatment may help to reduce the incidences and mortality rates of tumors associated with Lynch syndrome.

Background: Knowledge on periprosthetic infection and mortality rate following total knee arthroplasty (TKA) is essential for justifying this treatment in patients with cancer; however, relevant data from population-based studies are lacking. Therefore, we examined 1-year periprosthetic infection, mortality, and 5-year relative survival rates in cancer patients who underwent TKA., Methods: This is a population-based cohort study based on analysis of the Taiwan National Health Insurance Research Database. We enrolled a total of 2294 cancer patients and 131,849 patients without cancer (control group) who underwent TKA between January 1, 1997, and December 31, 2011. All patients were followed until death, infection, withdrawal from the National Health Insurance, or December 31, 2012., Results: The periprosthetic knee joint infection rate in cancer patients (1.73%) was not significantly higher than that in the control group (1.87%). However, the 1-year mortality rate was significantly higher (p < 0.05) in the cancer group (4.10%) than in the control group (1.66%). The overall 5-year survival rate was 93.10% as compared with those without cancers., Conclusion: Low periprosthetic knee joint infection rates and high 5-year relative survival rates indicate the feasibility of TKA in cancer patients. However, the surgeon should take into account a higher mortality rate in the first year following TKA.

Objective: To explore the correlation between JAK/STAT signaling pathways and pathogenesis of immune thrombocytopenia(ITP)., Methods: Twenty-six newly-diagnosed ITP patients was included in this study. They all meet the clinical and hematological criteria for the diagnosis of ITP, and patients with coronary heart disease, severe refractory hypertension, diabetes or with severe liver or kidney function incompetence were ruled out. 24 healthy control without autoimmune diseases, viral infectious diseases and with normal liver and kidney functions were also included. The expressions of Jak3, p-Jak3 mRNA, Stat3, and p-Stat3 were tested and the changes in levels of IL-21 mRNA, IL-21 cell secretion after DEX intervention and AG490 blockade were measured., Results: Compared with the healthy control, patients with ITP had significantly high expressions of Jak3, p-Jak3 mRNA, Stat3 and p-Stat3 protein, which significantly reduced after AG490 blocking (P<0.01). The expression of IL-21 mRNA and the secretion of IL-21 obviously decreased after DEX intervention, but increased after AG490 blocking(P<0.01)., Conclusion: The pathogenesis of ITP associates with the activation of JAK/STAT signaling pathways, and IL-21-mediated JAK/STAT signaling pathways play regulatory role in ITP.

Haishengsu (HSS) is an active natural extract isolated from Tegillarca granosa, which has previously been demonstrated to inhibit the proliferation of several types of cancer cells in vitro. Our previous study indicated that HSS may induce apoptosis to suppress growth of human hepatocellular carcinoma BEL‑7402 cells by activating Fas pathway. The present study demonstrated that HSS treatment induces the in vitro apoptosis of BEL‑7402 cells via the mitochondrial‑mediated apoptotic pathway detected by DNA fragmentation assay, caspase activity assay and transmission electron microscopy assay, and inhibits tumor xenograft growth in vivo. Alterations in apoptotic regulatory proteins were detected, including decreased expression of B‑cell lymphoma2 (Bcl‑2), upregulation of Bcl‑2‑associated X protein and mitochondrial cytochrome c release, and downstream activation of apoptotic signaling. Furthermore, apoptotic induction was caspase‑dependent, as indicated by cleavage of the caspase substrate, poly (ADP‑ribose) polymerase. Oral administration of 62.5‑250 mg/kg HSS markedly educed the growth of hepatocellular carcinoma tumor xenografts in nude mice. In addition, immunohistochemical staining for caspase‑3 protein and transmission electron microscopy further indicated the induction of apoptosis in these tumor tissues. Taken together, the present study demonstrated that HSS may effectively induce apoptosis to suppress the growth of BEL‑7402 cells in vitro and in vivo, and therefore may hold promise for further development as a novel cancer therapy.

This study aims to explore the correlation between serum 25-hydroxyvitamin D and thyroid hormones during the second trimester. In total, 277 pregnant women at 13-28 weeks of gestation were enrolled. According to the level of thyrotropic-stimulating hormone, they were divided into a reduced TSH group, a normal TSH group and an elevated TSH group. In this study, we found that the prevalence of vitamin D deficiency was as high as 94.58%. The 25-hydroxyvitamin D level in the reduced TSH group was lower than that in the normal thyroid function group (p = .0005), and the 25-hydroxyvitamin D level in the elevated TSH group was higher than that in normal TSH group (p=.0339). A positive correlation was observed between 25-hydroxyvitamin D and thyrotropic-stimulating hormone (r = 0.3034, p = .0000). Furthermore, 25-hydroxyvitamin D was negatively correlated with the free thyroxine level (r = -0.1286, p = .0323) as well as the free triiodothyronine level (r = 0.1247, p = .0380). These data suggest that the relationships between 25-hydroxyvitamin D and thyroid parameters were characterized during the second trimester. Pregnant women in the second-trimester who are diagnosed with transient hyperthyroidism should be evaluated for the possibility of vitamin D deficiency.

Hepatocarcinoma is one of the most lethal malignancy haunting the Chinese population, which is partially due to the difficulties in diagnosis at an early stage. The search for a biomarker that could signify the presence and progress of hepatocarcinoma is never ended. MicroRNAs are 22-nt RNAs that could bind to 3' UTR of target mRNAs, mediating degradation of mRNAs or inhibiting the translation. Although much has been investigated, the role of miR-124 in hepatocarcinoma remained elusive. We first detected aberrant expression level of miR-124 in HCC tissues of 112 patients. By exploring the clinical parameters, we found a significantly inverse correlation between miR-124 level and TNM stages. Consistent with this, the survival analysis indicated the association of low miR-124 with longer survival time. Subsequent forced expression miR-124 resulted in reduced cell viability of Hep3B and SMMC-7221, which cell lines have high and low background expression of miR-124, respectively. TargetScan prediction rendered a subset of target candidates, which were selected for experimental validation, KLF4 was subject to luciferase assay. Ectopic expression of KLF4 increased the sphere formation ability and CD44/133-positive cell numbers, which can be reversed by abundant expression of miR-124, suggesting that KLF4 is a functional target of miR-124 in tumourigenesis and cancer progression of HCC.

Escherichia coli (E. coli) O157:H7 is an important food‑borne pathogen with a low infective threshold and high resistance to treatment. There are currently a number of detection methods available, however, the majority are time‑consuming, complex and expensive, thus it is hard for these methods to be applied in routine detection. Therefore, there is urgent requirement to develop more sensitive, rapid and specific detective techniques. In the present study, an immuno‑biosensor based on the interference of load to the F0F1‑ATPase rotation, indicated by the fluorescence fluctuation, was constructed to detect O157:H7. The results demonstrated a good linear relationship (R2=0.9818) between antigen concentration (range, 102 cfu to 104 cfu) and the fluorescence intensity. The detection signals of the samples containing 102 cfu/well and 104 cfu/well E. coli O157:H7 were significantly stronger than the signal produced by the control sample (P<0.01). Due to its higher sensibility and simplicity when compared with the current methods applied, the results of the present study indicate a promising future for the application of this technique in detecting food source pathogens.

Objective: To construct a cell model of 4.1R gene knockout in murine macrophage cell line RAW264.7 using CRISPR/Cas9 technique., Methods: Three high?grade small?guide RNAs (sgRNAs) that could specifically identify 4.1R gene were synthesized and inserted into lentiCRISPRv2 plasmid. RAW264.7 cells were infected with sgRNA?Cas9 lentivirus from 293T cells transfected with the recombinant sgRNA?lentiCRISPRv2 plasmid, and the positive cells were screened using puromycin and the monoclonal cells were obtained. The expression of 4.1R protein in the monoclonal cells was measured by Western blotting, and the mutation site was confirmed by sequence analysis. Result A 4.1R gene knockout RAW264.7 cell line was obtained, which showed a 19?bp deletion mutation in the 4.1R gene sequence and obviously enhanced proliferation., Conclusion: We successfully constructed a 4.1R gene knockout macrophage cell line using CRISPR/Cas9 technique, which may facilitate further investigation of the function of 4.1R in macrophages.

In the present study, quercetin (QUR)-loaded mixed micelles (QUR-M) were prepared with the aim of improving the physicochemical and anticancer efficacy of QUR in lung cancer cells. The mixed micelles comprised tocopheryl polyethylene glycol 1000 succinate (TPGS) and a 1,2-distearoyl- sn -glycero-3-phosphatidylethanolamine derivative of polyethylene glycol. The nanosized QUR-M exhibited a pH-responsive and controlled release of QUR that is likely to be beneficial in cancer treatment. The results of an MTT assay clearly demonstrated that the anticancer effect of QUR-M in A549 cancer cells was stronger compared with that of free QUR at 24 and 48 h time points. The half-maximal inhibitory concentrations of QUR and QUR-M were observed to be 12.45 and 6.42 µg/ml, respectively. When stained with Hoechst 33342 and observed using a confocal laser scanning microscope, A549 cells treated with QUR-M exhibited severe chromatin condensation and apoptotic body formation of the nuclei. Overall, high intracellular uptake, sustained drug release and the presence of TPGS in the mixed micelles may result in an increased inhibitory effect against cell proliferation and improved therapeutic efficacy in lung cancers.

Objective: The aim of this study was to investigate whether corticosteroid use increases the incidence of repeated PVP or kyphoplasty patients older than 50 years., Methods: This study enrolled the data of 2,753 eligible patients from the Taiwan National Health Insurance Research Database who were exposed to systemic corticosteroids for at least 3 months during the first year preceding the first PVP or kyphoplasty. These steroid users were matched 1:1 in age, sex, and the index date of surgery with non-user controls during the enrollment period. All patients were followed for 1 year after the first PVP or kyphoplasty. The incidence of repeated PVP or kyphoplasty was compared between the steroid users and controls. A Cox proportional hazards model was developed to account for multiple confounding factors., Results: The number of patients receiving repeated PVP or kyphoplasty was 233 (8.46%) and 205 (7.45%) in the corticosteroid and control groups, respectively. The Cox proportional hazards model revealed no association between corticosteroid use and repeated PVP or kyphoplasty., Conclusions: Systemic corticosteroid use for longer than 3 months is not associated with repeated PVP or kyphoplasty within one year of surgery in patient older than 50 years old., Level of Evidence: Level III, Therapeutic study., (Copyright © 2017 Turkish Association of Orthopaedics and Traumatology.

Objective: To evaluate the efficacy and safety of neoadjuvant dose-dense or standard schedule chemotherapy with anthracyclines and taxanes for Luminal B (HER2-)Breast Cancer. Methods: From January 2010 to December 2014, 168 Luminal B (HER2-) breast cancer patients with stageⅡA-ⅢC confirmed by pathology were randomly assigned to receive one of the following regimens: (group A) concurrent TEC× 4 every 3 weeks, ( group B ) sequential EC× 4-T × 4 every 3 weeks, (group C ) dose-dense TEC× 4 every 2 weeks with G-CSF, (group D) sequential EC× 4(dose-dense)-T × 4 with dose-dense every 2 weeks . Results: A total of 168 patients completed the neoadjuvant chemotherapy as planned. The pathologic complete response (pCR) was 16.8% in the 4 groups.The pCR were 30.9% and 26.1% in the group C and group D respectively, significantly higher than patients with group A and group B(9.5%and 7.1%) ( P <0.05). Median follow-up was 43 months (IQR 3-63). The 3-year disease free survival (DFS) rate was 64.7%, 55.5%, 87.8% and 92.1% and the 3-year overall survival(OS)rate was 79.4%, 77.7%, 95.1%, 97.3% in the 4 groups respectively. Patients in the dose-dense group had better 3-year DFS and 3-year OS than those with the regular group.The side-effects could be evaluated in 154 patients.The incidence of neutropenia was 29.2% and 21.9% in the group C and group D versus 65.7%and 51.3% in the regular group( P <0.05), the incidence of nervous toxicity was 54.2%, 18.9%, 60.0%, 26.8% in the 4 groups respectively. The incidence of nervous toxicity in the dose-dense group was lower than that in the regular regimen group( P <0.05). Conclusion: Neoadjuvant dose-dense chemotherapy with anthracyclines and taxanes for Luminal B (HER2-)Breast Cancer was effective and can improve the pCR, DFS and OS.Comparing the two dose dense regimens, sequentially with anthracyclines and taxanes, the incidence of nervous toxicity were lower.

The species belonging to the genus Ptomaphagus Hellwig, 1795 (Coleoptera, Leiodidae, Cholevinae, Ptomaphagini) from eastern Asia are assigned to three species groups. Group yasutoshii has a single species: P. (s. str.) yasutoshii Nishikawa, 1993 from Taiwan, China. Group nepalensis with three species: P. (s. str.) nepalensis Perreau, 1988 from Nepal and P.

Specimens of other undescribed species of the group sibiricus are also recorded, revealing a high diversity of this genus in eastern Asia, especially in central and north Sichuan, China, which essentially remains to be investigated. Relevant morphological characters of the examined species are illustrated with colour plates, and their known distributions are mapped. A key to species of Ptomaphagus from eastern Asia is provided.

The prognostic effect of chemoradiotherapy in gastric cancer has been evaluated for decades while the results are still in debate and heterogeneous. We thus comprehensively updated the evidence through systematic review and meta-analysis to evaluate chemoradiotherapy in gastric cancer to determine its effect. Pubmed, EMBASE, and Cochrane Library from the earliest possible year to April 2017 were searched. Randomised controlled trials (RCTs) that assessed the effects of combined chemoradiotherapy for patients with gastric cancer compared with that of single chemotherapy were included. The main outcome measure was 5-year overall survival (OS) and the second was disease-free survival (DFS) or recurrence-free survival (RFS). Fifteen RCTs involving 3347 patients were included into this meta-analysis. Compared with single chemotherapy, the relative risk (RR) for 5-year OS for chemoradiotherapy was 1.05 (95% CI 0.88 to 1.25), with moderate heterogeneity across eligible trials ( I 2 = 55.7%, p = 0.016). Subgroup analyses and sensitivity analyses confirmed the consistent findings. We found that significant survival benefit for 5-year DFS/RFS for chemoradiotherapy over single chemotherapy (RR 0.89 95% CI 0.81 to 0.98) for patients with gastric cancer. This updated meta-analysis does not provide strong evidence for a 5-year survival benefit of chemoradiotherapy over chemotherapy alone in patients with gastric cancer. A clear advantage of chemoradiotherapy over chemotherapy has not been established. Further larger RCTs should be conducted to determine its true effect., Competing Interests: CONFLICTS OF INTEREST The authors declare no competing financial interests.

Omoglymmius ( s. str. ) wukong sp. n. (Coleoptera: Rhysodidae: Omoglymmiini) is described from Xizang, China. Relevant morphological characters of the new species are illustrated with colour plates, and known distribution of the subgenus Omoglymmius in the Himalayan region is mapped.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. BCL2 apoptosis regulator (BCL2) and marker of proliferation Ki-67 (Ki-67) are established prognostic markers, which have traditionally been assessed separately in DLBCL. However, no studies have evaluated the prognostic value of the combination of BCL2 and Ki-67 index. Thus, the present study aimed to analyze the prognostic value of combination of these two markers. Immunohistochemical analysis was used to assess the expression of BCL2 and Ki-67 in 274 cases of DLBCL. The BCL2/Ki-67 index demonstrated a significant association with decreased overall and progression free survival of patients with DLBCL, particularly for the germinal center B-cell-like subtype of DLBCL. Following multivariate analysis, the BCL2/Ki-67 index retained prognostic significance. Patients with coexpression of BCL2 and Ki-67 constituted a unique group with poor survival, thus novel therapies targeting BCL2 protein and high proliferative activity may improve the outcome of these patients.

Background and study aims  Previous studies describing the incidence of infection after colonoscopy and sigmoidoscopy are limited. The aim of this study was to determine the incidence of infection, and to propose a nomogram to predict the probability of infection following colonoscopy and sigmoidoscopy in symptomatic patients. Patients and methods  A nationwide retrospective study was conducted by analyzing the National Health Insurance Research Database of Taiwan. The incidence of infection within 30 days after colonoscopy and sigmoidoscopy was assessed and compared with a control group matched at a ratio of 1:1 based on age, sex, and the date of examination. Results  In all, 112 543 patients who underwent colonoscopy or sigmoidoscopy and 112 543 matched patients who did not undergo these procedures were included. The overall incidence of infection within 30 days after colonoscopy and sigmoidoscopy was 0.37 %, which was significantly higher than that of the control group (0.04 %; P  < 0.001). Diverticulitis, peritonitis, and appendicitis were the most common infections. Patients who underwent colonoscopy or sigmoidoscopy had a 9.38-fold risk of infection (95 % confidence interval, 6.81 - 12.93; P  < 0.001) compared with the control group. The predicted infection-free rates of the nomogram were closely aligned with the actual infection-free rates, with a bootstrapping concordance index of 0.763. Conclusions  Colonoscopy and sigmoidoscopy are associated with an increased risk of infection, which may occur after these procedures. Our nomogram may provide clinicians with an easy tool to evaluate the risk of infection after colonoscopy and sigmoidoscopy in symptomatic patients., Competing Interests: Competing interests: None, (© Georg Thieme Verlag KG Stuttgart · New York.)

Objective: There is initial evidence that the use of volatile anesthetics can reduce the postoperative release of cardiac troponin I, the need for inotropic support, and the number of patients requiring prolonged hospitalization following coronary artery bypass graft (CABG) surgery. Nevertheless, small randomized controlled trials have failed to demonstrate a survival advantage. Thus, whether volatile anesthetics improve the postoperative outcome of cardiac surgical patients remains uncertain. An adequately powered randomized controlled trial appears desirable., Design: Single blinded, international, multicenter randomized controlled trial with 1:1 allocation ratio., Setting: Tertiary and University hospitals., Interventions: Patients (n=10,600) undergoing coronary artery bypass graft will be randomized to receive either volatile anesthetic as part of the anesthetic plan, or total intravenous anesthesia., Measurements and Main Results: The primary end point of the study will be one-year mortality (any cause). Secondary endpoints will be 30-day mortality; 30-day death or non-fatal myocardial infarction (composite endpoint); cardiac mortality at 30day and at one year; incidence of hospital re-admission during the one year follow-up period and duration of intensive care unit, and hospital stay. The sample size is based on the hypothesis that volatile anesthetics will reduce 1-year unadjusted mortality from 3% to 2%, using a two-sided alpha error of 0.05, and a power of 0.9., Conclusions: The trial will determine whether the simple intervention of adding a volatile anesthetic, an intervention that can be implemented by all anesthesiologists, can improve one-year survival in patients undergoing coronary artery bypass graft surgery., (Copyright © 2017 Elsevier Inc.

Objective: To describe the distribution and drug resistance of pathogens at hematology department of Jiangsu Province from 2014 to 2015 to provide reference for empirical anti-infection treatment. Methods: Pathogens were from hematology department of 26 tertiary hospitals in Jiangsu Province from 2014 to 2015. Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or agar dilution method. Collection of drug susceptibility results and corresponding patient data were analyzed. Results: The separated pathogens amounted to 4 306. Gram-negative bacteria accounted for 64.26%, while the proportions of gram-positive bacteria and funguses were 26.99% and 8.75% respectively. Common gram-negative bacteria were Escherichia coli (20.48%) , Klebsiella pneumonia (15.40%) , Pseudomonas aeruginosa (8.50%) , Acinetobacter baumannii (5.04%) and Stenotropho-monas maltophilia (3.41%) respectively. CRE amounted to 123 (6.68%) . Common gram-positive bacteria were Staphylococcus aureus (4.92%) , Staphylococcus hominis (4.88%) and Staphylococcus epidermidis (4.71%) respectively. Candida albicans were the main fungus which accounted for 5.43%. The rates of Escherichia coli and Klebsiella pneumonia resistant to carbapenems were 3.5%-6.1% and 5.0%-6.3% respectively. The rates of Pseudomonas aeruginosa resistant to tobramycin and amikacin were 3.2% and 3.3% respectively. The resistant rates of Acinetobacter baumannii towards tobramycin and cefoperazone/sulbactam were both 19.2%. The rates of Stenotrophomonas maltophilia resistant to minocycline and sulfamethoxazole were 3.5% and 9.3% respectively. The rates of Staphylococcus aureus, Enterococcus faecium and Enterococcus faecalis resistant wards vancomycin were 0, 6.4% and 1.4% respectively; also, the rates of them resistant to linezolid were 1.2%, 0 and 1.6% respectively; in addition, the rates of them resistant to teicoplanin were 2.8%, 14.3% and 8.0% respectively. Furthermore, MRSA accounted for 39.15% (83/212) . Conclusions: Pathogens were mainly gram-negative bacteria. CRE accounted for 6.68%. The rates of Escherichia coli and Klebsiella pneumonia resistant to carbapenems were lower compared with other antibacterial agents. The rates of gram-positive bacteria resistant to vancomycin, linezolid and teicoplanin were still low. MRSA accounted for 39.15%.

Purpose: Studies on the association between continuous positive airway pressure (CPAP) treatment and liver diseases such as non-alcoholic fatty liver disease (NAFLD) and cirrhosis in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS) are limited. To the best of our knowledge, none exists that makes use of a national database in an Asian population. This study aims to evaluate the effects of CPAP treatment on patients with these two disorders in a retrospective, population-based study in Taiwan., Methods: Using the Taiwan National Health Insurance claims database, this study collected the data of OSAHS patients diagnosed between 2000 and 2008 and divided them into CPAP treatment and non-CPAP treatment groups. All subjects were followed up until 2010. Liver disease incidence and risk were calculated., Results: The CPAP group had a lower cumulative incidence rate of developing liver disease than the non-CPAP group within the observation periods (p < 0.001). After adjusting for age, gender, urbanization level, and comorbidities, the CPAP treatment group showed a lower risk of developing liver disease compared with the non-CPAP treatment group (sub-aHR of 0.66 (95% CI 0.55-0.80), p < 0.001)., Conclusions: Our observations suggest that CPAP treatment may play an important role to delay the progression of liver disease in OSAHS patients and decreases the incidence of liver disease among OSAHS patients. Thus, CPAP therapy may be a feasible way to decrease the risk of liver disease among patients with OSAHS.

A new species of flanged bombardier beetles is described from Jiangxi and Sichuan, China, Paussus (Scaphipaussus) zhouchaoi sp. n. (Coleoptera, Carabidae, Paussinae, Paussini).

Objective: To investigate potential value of fibrin related markers in patients with femoral fracture during perioperative period. Methods: Ninety-five patients were enrolled, including 39 males with (53±24) years old and 56 females with (73±13) years old, of which 44 fracture on caput femoris, 34 collum femoris and 17 shaft of femur. Sampling on the day before operation and 1(st,) 3(rd,) 5(th) days after operation, fibrin monomer (FM), D-dimer(DD), fibrinogen degradation product (FDP) and other coagulation assays were detected by reagents from Stago. Difference in day-to-day and between surgical sites were analyzed with general linear model (repeated measures). Results: FDP level on pre-operation, 1(st,) 3(rd,) 5(th) day after operation were 7.88(5.19, 12.12), 15.68(9.84, 29.48), 8.44 (6.27, 12.49) and 10.28 (7.56, 14.00) mg/L, the value of fibrin monomer were 5.00 (5.00, 6.03), 9.89(5.04, 30.12), 5.00 (5.00, 6.04) and 5.02(5.00, 5.76) mg/L. The value of D-Dimer were 2.24(1.41, 3.60), 4.78(2.74, 9.18), 2.60(1.79, 3.88) and 2.91(2.20, 3.85) mg/L, respectively, each parameter changs statistically during observation ( Z =4.758, 6.027, 3.238 respectively, P <0.05). On the 5th day after surgery, fibrin monomer in patients with venous thrombus embolism (VTE) were higher than that in patients without VTE, 10.18(7.24, 28.11) mg/L vs 5.10(5.00, 6.73) mg/L ( Z =-1.580, P <0.05), which showed potential value evaluating of post-operative VTE. No statistical changes were found in prothrombin time or thrombin time (TT) ( P >0.05), but activated partial thromboplastin time (APTT) varied from day to day in (38.1±4.9), (40.8±5.2), (45.1±6.2) and (41.9±6.3)s with statistically difference ( F =7.127, P <0.05). Similarly, fibrinogen changed statistically in (5.01±0.94), (4.99±1.35), (6.00±1.75), (5.81±1.38)g/L ( F =8.927, P <0.05). Conclusion: Fibrin monomer, additional to markers as D-dimer, shows its value on activated coagulation associated to post-operative thromboembolism for patients receiving femoral surgery.

Objective: To investigate the efficacy of autologous peripheral blood hematopoietic stem cell transplantation(auto-PBHSCT) combined with adoptive immunotherapy for patients with B lymphocyte malignant lymphoma(ML)., Methods: A total of 110 cases of ML treated with adoptive immunotherapy after auto-PBHSCT from January 2000 to December 2009 were enrolled in adoptive immunotherapy group (treated group), while 74 cases of ML treated without adoptive immunotherapy after auto-PBHSCT from January 1995 to December 1999 were used as control group. The efficacy of 2 groups were analyzed and compared, 110 case of ML in treated group included 78 cases of non-Hodgkin's lymphoma(NHL), 32 cases of Hodgkin's lymphoma(HL),74 cases of ML in control group included 52 NHL and 22 HL. All of the patients were treated sequentially with chemotherapy regimens for 6 courses. After that, all the patients received auto-PBHSCT. After hematopoietic reconstruction, the patients in treated group were given 6 courses of adoptive immunotherapy(rhIL-2 100 WU/day for 10 days monthly for each course), while the patients in control group were not given immunotherapy. All the patients were followed-up for more than 5 years., Results: There was one patient in each group, who died of liver failure and cerebral hemorrhage respectively within 3 and 2 months, and all the other patients achieved hematopoietic reconstruction. Following-up for 1, 3, 5 years, the disease-free survival (DFS) rate in treated group was 97.3%,93.6%,87.3% while 91.9%, 73.0%, 64.9% in control group. Following-up for 3 and 5 years, there was very significant difference in DFS between 2 groups(P<0.01). The 1,3 and 5 year DFS rate of patients in stage I/II and III/IV in the treated group were 100%,100%,91.7% and 96.5%,91.9%,86.0% respectively while DFS of control group was 100%, 93.3%, 86.7% and 89.8%, 67.8%, 59.3%, there was a significant difference in 3 and 5 years DFS of III/IV stage patients between 2 groups (P<0.01). The 1,3 and 5 year DFS rate of HL patients were 100%, 93.8%,84.4% in treated group and 100%,72.7%,59.1% in control group respectively. There was significant difference in 3 and 5 years DFS of HL between 2 groups (P<0.05). The 1,3 and 5 year DFS rate of stage I/II HL patients were 100%,100%,88.9% in treated group and 100%,100%,80.0% in control group. The 1,3 and 5 year DFS of HL patients in stage III/IV was 100%,91.3%,82.6% and 94.1%,64.7%,52.9% respectively. There was significant difference in 3 and 5 years DFS of III/IV stage of HL patients between 2 groups (P<0.05). The 1,3 and 5 year DFS rate of NHL patients is 96.2%, 93.6%,88.5% in treated group and 90.4%,73.1%,65.4% in control group respectively. There was a significant difference in 3 and 5 years DFS of NHL between 2 groups(P<0.01). The 1,3 and 5 year DFS rate of stage I/II NHL patients was 100%, 100%, 93.3.9% in treated group and 100%, 90%, 90.0% in control group, respectively. The 1,3 and 5 year DFS of NHL patients in stage III/IV is 95.2%, 92.1%,87.3% and 88.1%,69.0%, 59.5% respectively. There was significant difference in 3 and 5 years DFS of III/IV stage NHL patients between 2 groups (P<0.05)., Conclusion: Therapeutic efficacy is satisfactory for the patients of B lymphocyte ML treated with adoptive immunotherapy after auto-PBHSCT, especially benefited the patients of stage III/IV significantly.

A total of twenty genotypes of peanut (Arachis hypogaea) were used to investigate the differences in nitrogen (N) utilization characteristics in a pot experiment with 15 N isotope tracing analysis. Results showed the main N sources for peanut in high fertility soils following as soil N source > N fixed by root nodule source > fertilizer N source. The N uptake and accumulation in peanut from total N and the three N supplied sources (fertilizer N, soil N and N fixation) varied among the different genotypes. N fixation source had the largest genetic variation among the twenty genotypes while genetic variation for fertilizer N source and soil N source were lower and similar. Significant differences showed among the twenty genotypes in pod producing efficiency of N and N use efficiency, and the highest values were respectively 3.6 and 2.1 times of the lowest values. There were also significant differences among the twenty genotypes in the harvest indexes of total N, fertilizer N source, soil N source and N fixation source, and the largest variation showed in the harvest index of N fixation source. The pod yields significantly or extremely significantly corrected with N accumulation amounts from different N sources, N harvest index, pod producing efficiency of N, and N use efficiency. According to N uptake and accumulation and pod yield, four major types of peanut were classified, namely high total N accumulation high yield type, high fertilizer N source high yield type, high soil N source high yield type, and high N fixation source high yield type. Four of the twenty genotypes had all characteristics of the four major types.

Background: The activation of the arginine vasopressin system may be involved in the pathology of stroke and diabetes. In this study, we therefore evaluated the short-term prognostic value of early measurement of plasma copeptin levels in Chinese patients with type 2 diabetes mellitus (T2DM) and acute ischemic stroke (AIS)., Methods: From July 2014 to June 2015, all T2DM patients with first-ever AIS were included. Plasma levels of copeptin were tested at admission. The prognostic value of copeptin to predict the functional outcome and mortality 3months after stroke was compared with the National Institutes of Health Stroke Scale score and with other known outcome predictors., Results: We recorded 247 stroke patients with T2DM. The copeptin levels were obtained in those patients with a median value of 14.3pmol/L (IQR, 9.5-17.1pmol/L). At 3-month follow-up, a favorable functional outcome was found in 86 patients (34.8%). Plasma copeptin levels in patients with an unfavorable outcome were significantly greater than those in patients with a favorable outcome (16.2 [IQR, 12.2-20.3] vs. 12.4 [IQR, 8.6-15.2] pmol/L; Z=5.399; P<0.0001). In univariate logistic regression analysis, with an unadjusted OR of 1.123 (95% CI, 1.072-1.177, P<0.001), copeptin had a strong association with unfavorable functional outcome. In multivariate analyses, a copeptin level in the highest inter-quartile (>17.1pmol/L) was associated with a higher risk of unfavorable functional outcome (OR=4.62; 95% CI=2.63-9.21; P<0.001). After adjusting for other outcome predictors, a copeptin level in the highest inter-quartile (>17.1pmol/L) was associated with a higher risk of mortality (OR=5.12; 95% CI=2.20-11.38; P<0.001)., Conclusion: Our study suggested that copeptin levels may reliably predict short-term stroke prognosis at its onset in Chinese patients with T2DM and stroke., (Copyright © 2016 Elsevier Inc.
