It remains controversial to claim blood pressure (BP) as a leading risk factor for high risk of death in peritoneal dialysis patients, and less is known about the relationship between BP and mortality in Chinese peritoneal dialysis patients.From Zhejiang Renal Data System in China, we collected data on patients treated and followed up at 98 peritoneal dialysis centres from 2008 to 2016. The associations of BP parameters [SBP, DBP, mean arterial pressure (MAP) and pulse pressure (PP)] with all-cause and cardiovascular mortality were examined. We fitted Cox models for mortality with penalized splines using nonparametric smoothers. Several sensitivity analyses were performed to confirm the robustness of our primary findings.A total of 7335 Chinese peritoneal dialysis patients were included. During a median follow-up of 35.8 months, 1281 (17.5%) patients died. SBP, DBP, MAP follow a U-shaped pattern of both all-cause and cardiovascular mortality. PP presents a reverse L-shaped association with all-cause mortality. Either a higher (SBP141, DBP85 or MAP102 mmHg) or lower (SBP119, DBP67 or MAP88 mmHg) BP tends to have a significantly higher all-cause and cardiovascular mortality risk. Higher PP (60 mmHg) is related to a higher risk of all-cause mortality, but not cardiovascular mortality. These associations remain the same in our competing risk analysis and subgroup analyses.These data indicate U-shaped associations of SBP, DBP and MAP with all-cause mortality and cardiovascular mortality, respectively, and a reverse L-shaped association of PP with all-cause mortality. Further studies are needed to reliably establish the optimal BP targets for better hypertension control in peritoneal dialysis patients.

Background Vancomycin is the standard therapy for methicillin-resistant Staphylococcus aureus (MRSA) infection; however, nephrotoxicity happened with a high incidence of 15%~40%. Weighting the risk before receiving vancomycin treatment facilitates timely prevention of nephrotoxicity, but no standardized strategy exists for this purpose. Methods A retrospective cohort study was performed. A total of 524 hospitalized patients treated with vancomycin were included in this study. They were divided into derivation cohort (n=341) and externally validation cohort (n=183) according to their admission time. Using univariate and multivariable logistic regression, we identified potential predictors of vancomycin-associated acute kidney injury (AKI) and developed a risk score by plotting nomogram. The predictive performance of this novel risk score was assessed and validated by discrimination and calibration. Besides, the risk score was also compared with existing prediction models according to integrated discrimination index (IDI) and net reclassification index (NRI). Results The incidence of AKI was 16.1% (55/341) in the derivation cohort and 16.4% (30/183) in the validation cohort. Three factors (vancomycin serum trough concentration, piperacillin/tazobactam and furosemide) were determined as predictors for vancomycin-associated AKI. The established three-item risk score showed a comparable discrimination in both derivation cohort (AUC=0.793, 95% CI: 0.732-0.855) and validation cohort (AUC=0.788, 95% CI: 0.698-0.877). The risk score also demonstrated a good calibration in the derivation cohort (χ2=6.079, P=0.638>0.05) and validation cohort (χ2=5.665, P=0.686>0.05). Compared with prediction by Cmin alone, this risk score significantly improved reclassification accuracy (IDI=0.050, 95% CI: 0.024-0.076, P

Ravidasvir (RDV) is a novel oral hepatitis C virus NS5A inhibitor. This study aimed to evaluate the pharmacokinetics and safety of RDV and the drug-drug interactions between RDV and ritonavir-boosted danoprevir (DNVr) in healthy adults. In the 1st study, healthy volunteers were administered single oral doses of 100, 200, and 300 mg of RDV and 200 mg once daily for 7 days. The 2nd study was a randomized, double-blinded, and placebo-controlled sequential design (day 1 for 200 mg of RDV alone, day 7 for 100 mg/100 mg of DNVr, day 13 for 200 mg of RDV plus 100 mg/100 mg DNVr, followed by 200 mg of RDV once daily with 100 mg/100 mg of DNVr twice daily for 10 days). The results showed that RDV exposure increased in a dose-proportional manner following a single dose with no evidence of accumulation with multiple doses. Coadministration with DNVr (100 mg/100 mg, twice daily) resulted in a 2.92-fold and 1.99-fold increase in minimum plasma concentration at steady state (C(min,ss)) and area under the concentration-time curve at steady state (AUC(τ)) of RDV, respectively. With coadministration of RDV, maximum plasma concentration (C(max)) and area under the concentration-time curve from 0 to 12 h (AUC(0–12)) of DNV increased 1.71-fold and 2.33-fold, respectively. We did not observe any significant changes in ritonavir exposure. Both single and multiple doses of RDV with or without DNVr were well tolerated. The favorable pharmacokinetic and safety results support ravidasvir’s continued clinical development and treatment.

The purpose of this study was to assess the safety profile and the relative bioavailability of two FDC products containing 10 mg melitracen and 0.5 mg flupentixol from two different manufacturers, in order to acquire adequate pharmacokinetic evidence for registration approval of the test formulation.Methods: The study was designed as a single-dose, randomized, open-label, 2-period crossover study under fasted or fed conditions in healthy Chinese subjects. Twenty-four subjects (16 men and 8 women) were selected for fasted study, and another 24 cases (16 men and 8 women) were in fed study. Each subject was randomized at the beginning to receive either a single dose of the reference FDC or the test FDC tablet during the first period. Following two-week washout period, all subjects received the alternate formulation during the second period. Blood samples were collected up to 144 hrs after administration. Pharmacokinetic parameters, including Cmax, Tmax, AUC0-t, AUC0-∞, t½, CL/F, and Vd/F were acquired based on the time versus concentration profiles. Then, the geometric mean ratios (GMR) and corresponding 90% CIs were calculated for the determination of bioequivalence analysis. Safety assessment included changes in vital signs and laboratory tests, physical examination findings, and incidence or reports of adverse events (AEs).Results: The present study has clearly indicated the test and the reference FDC products are bioequivalent in terms of rate and extent of drug absorption. GMR of Cmax, AUC0–t, and AUC0-∞ for both flupentixol and melitracen between the two formulation FDC products, and corresponding 90% CIs, were all within the range of 80% to 125% under fasted or fed conditions. Both the test and the reference FDC products indicated good tolerance in all volunteers.

Ethnopharmacological usages Fructus Alpiniae oxyphyllae (A. oxyphylla) is an important medicinal plant that is used not only as an edible fruit, but also as an important traditional medicine for benefiting cognitive performance and alleviating a wide spectrum of diseases. Such as; warming kidney, securing essence and arresting polyuria, as well as warming the spleen and stopping diarrhea and saliva. Aims The purpose of this review is to provide updated, comprehensive and categorized information on the traditional uses, phytochemistry and pharmacological research of A. oxyphylla in order to explore their therapeutic potential and establish a solid foundation for directing future research. Materials and methods All the available information on A. oxyphylla was collected via electronic search (using Pubmed, SciFinder, Scirus, Google Scholar and Web of Science) and additionally a number of unpublished resources, (e.g. books, Ph.D. and M.Sc. dissertations, government reports). Results Phytochemical research on A. oxyphylla has led to the isolation of components such as essential oils, terpenes, diarylheptanoids, flavones, nucleobases and nucleosides, steroids and others. Crude extracts, fractions and phytochemical constituents isolated from A. oxyphylla showed a wide spectrum of in vitro and in vivo pharmacological activities like neuroprotective, anti-diarrheal, anti-diuretic, anti-neoplastic, anti-oxidant, anti-inflammatory, anti-allergic, viscera protective and anti-diabetic activities. Neuroprotective, anti-cancer, anti-diarrheal and anti-diuretic effects are major areas of research conducted on A. oxyphylla. Conclusions Modern pharmacological studies have supported many traditional uses of A. oxyphylla, including nervous system, urinary system and gastrointestinal system disease. There was convincing evidence in experimental animal models in support of its neuroprotection, secure essence, reduce urination, and anti-carcinogenic effects. However, all the reported pharmacological activities were carried out at pre-clinical level and the authors urge further investigation in clinical trials about these therapeutic fields of A. oxyphylla.

The effects of multiple-dose administration of tenofovir disoproxil fumarate (TDF) on the pharmacokinetics of morinidazole (MOR) were compared in healthy subjects. MOR exposure was similar, with an area under the curve from 0 h to infinity (AUC0-∞) treatment ratio for MOR+TDF/MOR of 1.01 (90% confidence interval, 0.97 to 1.06). No relevant differences were observed regarding plasma exposure of metabolites. Renal clearances of MOR and its metabolites were not affected by TDF., The effects of multiple-dose administration of tenofovir disoproxil fumarate (TDF) on the pharmacokinetics of morinidazole (MOR) were compared in healthy subjects.

No unexpected safety or tolerability issues were observed.

Background and Objective This study was performed in healthy Chinese subjects to evaluate the safety and pharmacokinetic/pharmacodynamic characteristics of a novel injection formulation of dexlansoprazole in the context of single and multiple administration, compared with the original lansoprazole injection. Methods Helicobacter pylori-negative healthy volunteers were recruited, and 70 participants were enrolled into five dosing groups (seven males and seven females in each group), including 15 mg once daily (qd), 15 mg every 12 h (q12h), 30 mg qd and 30 mg q12h of dexlansoprazole treatment for 5 days, as well as 30 mg q12h of lansoprazole treatment for 5 days. Blood samples were collected at scheduled time spots postdose on day 1 (first dose) and day 5 (last dose). Twenty-four-hour intragastric pH was continuously monitored on day 0 (baseline) and days 1 and 5. Dexlansoprazole and S-lansoprazole in human plasma were determined by validated chiral liquid chromatography with tandem mass spectrometry, and the pharmacokinetic parameters were determined by a non-compartmental method using Phoenix WinNonlin software. Safety assessment included changes in vital signs and laboratory tests, physical examination findings, and incidence or reports of adverse events. Results The half-life (t½) and clearance (CL) of dexlansoprazole were 1.76–2.06 h and 4.52–5.40 L/h, respectively, while the t½ and CL of S-lansoprazole were 0.87–1.02 h and 34.66–35.98 L/h, respectively. No drug accumulation after repeated administration was noted. Administration of lansoprazole 30 mg resulted in higher area under the concentration-time curve from time zero to the last measurable concentration (AUCt) of dexlansoprazole than that of dexlansoprazole 15 mg (p = 0.026). Zero to 24 h after q12h multiple dosing, median and mean intragastric pH, percentage of time with the intragastric pH above 4.0 [TpH ≥ 4.0(%)] and percentage of time with the intragastric pH above 6.0 [TpH ≥ 6.0(%)] in the dexlansoprazole 15 mg q12h group were 6.07 ± 0.61, 5.70 ± 0.76, 83.58 ± 12.34, and 53.70 ± 17.06, respectively, which was similar to the lansoprazole 30 mg q12h group, i.e. 6.15 ± 0.62, 5.88 ± 0.67, 87.26 ± 12.08 and 57.00 ± 16.35, respectively. A weak positive correlation between dexlansoprazole AUCt and baseline-adjusted TpH ≥ 4.0(%) over 0–24 h was observed, with Pearson correlation coefficients of 0.437 (p = 0.029), while no correlation was observed between AUCt and baseline-adjusted TpH ≥ 6.0(%) over 0–24 h. Conclusion Every 12 h intravenous dosing of dexlansoprazole up to 30 mg for 5 days was safe and well-tolerated in healthy Chinese subjects. Every 12 h dosing of dexlansoprazole 15 mg has a comparable effect of gastric acid inhibition as lansoprazole 30 mg q12h. Trial Registration ClinicalTrials.gov ID NCT03120273.

Purpose: The aim of this study was to compare the pharmacokinetics and safety between two vinorelbine formulations [a new oil-in-water emulsion formulation (ANX) versus a previously marketed solution formulation (Navelbine)] in Chinese patients with advanced non-small cell lung cancer (NSCLC). Method: This was a single-center, randomized, open-label study. Eligible patients aged 18-70 years who had histologically or cytologically confirmed NSCLC were enrolled. In cycle 1, the patients alternatively received the two formulations (30 mg/m2, given as a 10-min infusion) with a 7-day interval. Samples for pharmacokinetic analysis were taken during cycle 1. For all subsequent 21-day cycles (maximum four cycles), ANX was administered on days 1 and day 8. Bioequivalence analysis was performed on Cmax, AUClast, and AUCinf. The safety profiles and anti-tumor effects were also determined. Results: From March 2013 to January 2015, 24 patients were enrolled and 20 were eligible for pharmacokinetic evaluation. The 20 subjects in the pharmacokinetic analysis set had a median age of 61 years (range, 37-70 years), and 15 patients were male (75%). Mean vinorelbine Cmax values for ANX and Navelbine were 1,317.40 and 1,446.30 ng/mL, respectively. Corresponding AUClast values were 797.08 and 924.26 ng·h/mL, respectively. AUCinf values were 830.14 and 957.16 ng·h/mL, respectively. Treatment ratios of the geometric means were 90.00% (90% CI, 83.22-99.07%) for Cmax, 86.92% (90% CI, 80.91-93.37%) for AUClast, and 87.44% (90% CI, 82.08-93.16%) for AUCinf. These results met the required 80-125% bioequivalence criteria. The most frequently reported adverse events after vinorelbine administration were neutropenia, leucopenia, neutropenic fever, and constipation. Conclusion: At therapeutic dosage levels, pharmacokinetic behavior and safety profiles were similar for both formulations. Chinese National Registry Code: ChiCTR-IPR-15005856.

Thus, the porous media pre-cooler could be applicable to the turboramjet.

Supplemental Digital Content is available in the text, To develop a classification model for accurately discriminating common infectious diseases in Zhejiang province, China. Symptoms and signs, abnormal lab test results, epidemiological features, as well as the incidence rates were treated as predictors, and were collected from the published literature and a national surveillance system of infectious disease. A classification model was established using naïve Bayesian classifier. Dataset from historical outbreaks was applied for model validation, while sensitivity, specificity, accuracy, area under the receiver operating characteristic curve (AUC) and M-index were presented. A total of 146 predictors were included in the classification model, for discriminating 25 common infectious diseases. The sensitivity ranged from 44.44% for hepatitis E to 96.67% for measles. The specificity varied from 96.36% for dengue fever to 100% for 5 diseases. The median of total accuracy was 97.41% (range: 93.85%–99.04%). The AUCs exceeded 0.98 in 11 of 12 diseases, except in dengue fever (0.613). The M-index was 0.960 (95%CI 0.941–0.978). A novel classification model was constructed based on Bayesian approach to discriminate common infectious diseases in Zhejiang province, China. After entering symptoms and signs, abnormal lab test results, epidemiological features and city of disease origin, an output list of possible diseases ranked according to the calculated probabilities can be provided. The discrimination performance was reasonably good, making it useful in epidemiological applications.

Objective: A generic vaginal progesterone gel has recently been developed in China. Little is known about its pharmacokinetic properties in Chinese subjects. The purpose of our study was to investigate the pharmacokinetics of three forms of vaginal progesterone gel (test formulations at 4 and 8% strength vs. a reference formulation: Crinone 8%) in Chinese healthy post-menopausal women. Methods: This study consisted of two parts study. The part 1 study was a single-center, open-label, 3-period study. Twelve healthy post-menopausal women were to evaluate the safety and pharmacokinetics of 45 mg vaginal progesterone gel (Test 4%) following single dose and multiple doses administered once every other day (q.o.d.) for six times or once daily (q.d.) for 6 days. The part 2 study was a randomized, open-label, 3-stage crossover study. Twelve post-menopausal women received 90 mg vaginal progesterone gel (Test 8%) or 90 mg Crinone (Reference 8%) following single dose and multiple doses (q.o.d. or q.d.). Plasma concentrations of progesterone were measured up to 72 h by using a validated liquid chromatography tandem-mass spectrometry method. The primary pharmacokinetic parameters, maximum plasma concentration (Cmax) and area under the plasma concentration–time curve (AUC) from time zero to last measurable concentration (AUC0-t) and extrapolated to infinity (AUC0-∞) were compared by an analysis of variance using log-transformed data. Results: Totally 24 subjects were enrolled in and completed the study. Following single dose, The geometric mean Cmax values for Test 4%, Test 8%, and Crinone 8% were 6.35, 10.34, 10.45 ng/mL, and their geometric mean AUC0-t (AUC0-∞) were 113.73 (118.00), 169.39 (173.98), and 190.07 (201.13) ng⋅h/mL, respectively. The mean T1/2 values of progesterone were 11.00, 10.92, and 11.40 h, respectively. For 8% test formulation vs. reference, the 90% CIs of the least squares mean test/reference ratios of Cmax, AUC0-t, and AUC0-∞ were 78.32–124.85%, 54.31–146.24%, and 53.64–137.75, respectively. The most frequent adverse events were increased vaginal secretions, most of which were of mild intensity and considered related to treatment. Conclusion: Results with single and multiple doses of vaginal progesterone gel suggest similar pharmacokinetics properties between test formulations and Crinone 8%. Overall, vaginal progesterone gel was well tolerated.

Highlights? Presented a novel inter-domain communication approach (IVCOM) for virtual machine. ? Using bypassing protocol stacks, shunning page flipping methods. ? IVCOM applies a direct communication channel between domain 0 and U. ? IVOCM can improve the latency and throughput in para-virtualized environment. ? IVCOM can greatly reduce the VM entry/exit operations. In virtualization technology field, researches mainly focus on strengthening the isolation barrier between virtual machines (VMs) that are co-resident within a single physical machine. At the same time, there are many kinds of distributed communication-intensive applications such as web services, transaction processing, graphics rendering and high performance grid applications, which need to communicate with other virtual machines at the same platform. Unfortunately, current inter-VM communication method cannot adequately satisfy the requirement of such applications. In this paper, we present the design and implementation of a high performance inter-VM communication method called IVCOM based on Xen virtual machine environment. In para-virtualization, IVCOM achieves high performance by bypassing some protocol stacks and privileged domain, shunning page flipping and providing a direct and high-performance communication path between VMs residing in the same physical machine. But in full-virtualization, IVCOM applies a direct communication channel between domain 0 and Hardware Virtualization based VM (HV2M) and can greatly reduce the VM entry/exit operations, which has improved the HV2M performance. In the evaluation of para-virtualization consisting of a few of benchmarks, we observe that IVCOM can reduce the inter-VM round trip latency by 70% and increase throughput by up to 3 times, which prove the efficiency of IVCOM in para-virtualized environment. In the full-virtualized one, IVCOM can reduce 90% VMX transition operations in the communication between domain 0 and HV2M.

The pharmacokinetics (PKs) of febuxostat varies among individuals, while the main causes are still unknown. We investigated whether the polymorphisms of UGT1A1 and UGT1A3 played an important role in the disposition of the drug after oral administration of febuxostat tablet in Chinese subjects. A total of 42 healthy subjects were from two previous independent clinical bioequivalence (BE) trials of febuxostat, in which the same reference formulation (ULORIC® tablet, 80 mg) was taken, and thus the PK data were combined for the evaluation of pharmacogenomic effect on febuxostat PKs. Our study clearly indicated that the area under the plasma concentration-time curve (AUC) in the heterozygote and homozygote of UGT1A1*6 (c.211G > A, rs4148323) was significantly higher than that in the wild-type. Meanwhile, the clearance (CL/F) exhibited a significant reduction by 22.2%. Interestingly, UGT1A1*28, in perfect linkage disequilibrium (LD) with UGT1A3*2a, significantly increased its clearance. These results indicate that UGT1A1*6 was an important factor influencing the drug disposition, thus providing a probable explanation for interindividual variation of febuxostat PKs in Chinese subjects. In addition, by considering of the different allele distribution of UGT1A1*6 and *28 in Eastern and Western populations, these findings might further interpret the ethnic difference of febuxostat PKs.

Part 3: Virtualization and Cloud Computing Technologies; International audience; To provide elastic cloud services with QoS guarantee, it is essential for data centers to provision Virtual Machine(VM) instances rapidly. Due to bandwidth bottleneck of centralized model, the P2P-like distribution schemes are recently adopted. However, most of them just focus on the transmission speed, but ignore the impact on network bandwidth, especially for cloud data centers which are connected by Wide Area Network(WAN). In this paper, we propose a bridgehead-employed VM image distribution system(BIDS), which aims to minimize the repetitive data flows of WAN while speeding up the image distribution. In BIDS, we also design a version based image sharing mechanism, which tries to make a balance between efficiency and management complexity. Besides, we implement a Remote Management Console(RMC). The final evaluation shows that BIDS is of high efficient and low overhead.

Background Genes in inflammatory pathways play a pivotal role in the development of colorectal cancer. We conducted a two-stage case-control study and aimed at screening the colorectal cancer-associated genetic variations in inflammatory genes. Methods Twenty-three candidate variants were genotyped in 952 primary colorectal cancer cases and 875 cancer-free controls from eastern China. Promising single nucleotide polymorphisms were further genotyped in 518 cases and 554 controls from middle China. Expression quantitative trait loci and differential gene expression analyses were performed for the associated gene. Results rs2282151 presented consistently significant associations with the risk of colorectal cancer in both stages (odds ratio (95 % confidence interval) = 1.30 (1.16–1.46), risk allele = C, P combined = 8.9E-6). Gene expression quantitative trait loci analyzes uncovered consistent cis-regulatory signals which showed that the C allele of rs2282151 was associated with increased expression level of heat shock protein 90 alpha family class B member 1 (HSP90AB1). Then we found that the mRNA expression levels of HSP90AB1 were significantly higher in tumor tissues than normal tissues (fold-change = 1.83) in 28 pairs of colorectal tissue samples. The expression difference was consistent with data from online datasets. Additionally, we observed notable peaks of H3K27ac and H3K4me3 near the first intron of HSP90AB1 using ChIP-seq data from multiple cell lines (including HCT116). Conclusions Our findings indicate that the C allele of the novel colorectal cancer-associated variant rs2282151 is associated with increased expression levels of HSP90AB1, which is expressed higher in colorectal tumor tissues than in normal tissues.

Background Previous studies indicated that type 2 diabetes mellitus (T2DM) might be associated with the risk of cancer. The aim of this study was to investigate the association between T2DM and the risk of developing common cancers in a Chinese population. Methods A population-based retrospective cohort study was carried out in the Nan-Hu district of Jiaxing city, Zhejiang province, China. The incidence of cancer cases among type 2 diabetic patients were identified through record-linkage of the Diabetic Surveillance and Registry Database with the Cancer Database from January 2002 to June 2008. The standardized incidence ratio (SIR) and 95% confidence interval (CI) were estimated for the risk of cancer among the patients with type 2 diabetes. Results The overall incidence of cancer was 1083.6 per 105 subjects in male T2DM patients and 870.2 per 105 in females. Increased risk of developing cancer was found in both male and female T2DM patients with an SIR of 1.331 (95% CI = 1.143-1.518) and 1.737 (1.478-1.997), respectively. As for cancer subtypes, both male and female T2DM patients had a significantly increased risk of pancreatic cancer with the SIRs of 2.973 (1.73-4.21) and 2.687 (1.445-3.928), respectively. Elevated risk of liver and kidney cancers was only found in male T2DM patients with SIRs of 1.538 (1.005-2.072) and 4.091 (1.418-6.764), respectively. Increased risks of developing breast cancer [2.209 (1.487-2.93)] and leukemia SIR: [4.167 (1.584- 6.749) ] were found in female patients. Conclusions These findings indicated that patients with T2DM have an increased risk of developing cancer. Additional cancer screening should be employed in the management of patients with T2DM.
