[ Objective/Meaning ] Based on the actual situation of the old revolutionary base areas, the path to give play to the advantages of red culture was explored, in order to provide beneficial theoretical and practical reference for the development of rural areas in the old revolutionary base areas and the realization of common prosperity.[ Methods/Procedures ] On the basis of field investigation, through the literature research and the analysis of induction, the role of red cultural resources on the rural development in the old revolutionary base areas was analyzed. Then, the value implication of developing the red culture to realize the common prosperity of the whole people, the comprehensive common prosperity, the co-construction common prosperity, and the gradual common prosperity in the old revolutionary base areas was summarized. And the realistic predicament of the development of rural red culture in the old revolutionary base areas was analyzed. Finally, the corresponding countermeasures and suggestions were put forward.[ Results/Conclusions ] There were some practical difficulties in the development of rural red culture in the old revolutionary base areas, such as the weak economic foundation, the remote geographical location, the lagging cultural construction, and the difficulties in grassroots governance. It was necessary to promote the red culture to boost the common prosperity of the old revolutionary base areas through the practical paths including creating the characteristic brand industry, building the red “nostalgic” villages, carrying forward the spirit of the old revolutionary base areas, and improving the ability of thematic governance.

Objective To explore the metabolite profile and metabolic pathways of newly diagnosed multiple myeloma (MM). Methods Gas chromatography-mass spectrometry (GC-MS) was employed for the high-throughput detection and identification of serum samples from 55 patients with MM and 37 healthy controls matched for age and sex from 2016 to 2017 collected at the First Affiliated Hospital of Soochow University. The relative standard deviation (RSD) of quality control (QC) samples was employed to validate the reproducibility of GC-MS approach. The differential metabolites between patients with MM and healthy controls were detected by partial least squares discrimination analysis ( PLS-DA), and t-test with false discovery rate ( FDR) correction. Metabolomics pathway analysis ( MetPA) was employed to construct metabolic pathways. Results There were 55 MM patients, including 34 males and 21 females. The median age was 60 years old (42-73 years old). There were 30 cases of IgG type, 9 cases of IgA type, 1 case of IgM type, 2 cases of non-secreted type, 1 case of double clone type and 12 cases of light chain type, including 3 cases of kappa light chain type and 9 cases of lambda light chain type. The result of QC sample test showed that the proportion of compounds with the RSD of the relative content of metabolites < 15% was 70.21% obtained by the reproducibility of GC-MS experimental data, which implied that the experimental data were reliable. A total of 17 metabolites were screened differently with the healthy control group, including myristic acid, hydroxyproline, cysteine, palmitic acid, L-leucine, stearic acid, methionine, phenylalanine, glycerin, serine, isoleucine, tyrosine, valine, citric acid, inositol, threonine, and oxalic acid (VIP>1, P< 0.05). Metabolic pathway analysis suggested that metabolic disorders in MM patients comprised mainly phenylalanine metabolism, glyoxylic acid and dicarboxylic acid metabolism, phosphoinositide metabolism, cysteine and methionine metabolism, glycerolipid metabolism, glycine, serine, and threonine metabolism. Conclusion Compared with normal people, patients with newly diagnosed MM have obvious differences in metabolic profiles and metabolic pathways. [ABSTRACT FROM AUTHOR]

As the background noise content in the actual measurement of horizontal centrifugal pump was large, and the fault characteristics were often submerged, resulting in poor mechanical fault diagnosis effect. In order to obtain its operation state and fault diagnosis in current time and accurately, a mechanical fault diagnosis method of horizontal centrifugal pump based on complementary ensemble empirical mode decomposition（CEEMD）-optimized k nearest neighbor（KNN） was proposed. Firstly, the mechanical fault acceleration signal of horizontal centrifugal pump was collected, and the signal was decomposed once by CEEMD to obtain the intrinsicmode function（IMF）. The correlation coefficient of IMF was obtained by the correlation coefficient method to determine the correlation component and uncorrelated component. Secondly, the uncorrelated component was processed by the improved wavelet threshold denoising method to extract the time-frequency fault features that could be analyzed by the reconstructed signal. Finally, a centrifugal pump experimental bench was built, and the above fault diagnosis methods were used to classify and diagnose the mechanical faults of the centrifugal pump.The results show that the signal-to-noise ratio（SNR） of the signal evaluation index after CEEMD noise reduction is 2.257 1, which is 0.438 1 higher than the original denoising method. After optimization, the accuracy of KNN classification for mechanical fault diagnosis of horizontal centrifugal pump can reach 96.7%, which can effectively identify faults and achieve the purpose of intelligent diagnosis.

Objective: To investigate and analysis the correlation between the expression levels of serum Interferon-γ (IFN-γ), erythrocyte sedimentation rate (ESR) and soluble interleukin receptor (sIL-2R) in children with acute lymphoblastic leukemia (ALL). Methods: From February 2017 to October 2020, 62 cases of children with acute lymphoblastic leukemia who were diagnosed and treated in the Department of Hematology of our hospital were selected as the ALL group, and the other 62 cases of healthy children who had physical examination in our hospital during the same period were selected as the control group. The serum IFN-γ, ESR, and sIL-2R levels were used to determine the immunophenotype and chromosome analysis of children in the ALL group, followed up the prognosis of the children and given correlation analysis. Results: The proportions of CD34+, CD117+, and karyotype abnormalities in the ALL group were 77.4 %, 58.1 %, 54.8 %, respectively, which were higher than those of the control group (27.4 %, 17.7 %, 14.5 %)(P<0.05). The levels of serum ESR and sIL-2R in the ALL group were higher than those in the control group, and the levels of IFN-γ were lower than those in the control group (P<0.05). In children in the ALL group, followed-up until December 1, 2021, the average follow-up time were 29.14± 4.28 months, the overall survival time were 18.29± 1.22 months, and the event-free survival time were 10.48± 0.33 months; there were 22 cases were died and 40 cases were survived, the mortality rate were 35.5 %. Spearman correlation analysis showed that serum IFN-γ, ESR, sIL-2R levels were correlated with CD34+ positive, CD117+ positive, abnormal chromosomal karyotype, overall survival time, event-free survival time (P<0.05). Multivariate logistic regression analysis showed that IFN-γ, ESR, sIL-2R were important factors affected the prognosis and death of children with acute lymphoblastic leukemia (P<0.05). Receiver operating characteristic curve (ROC) showed that the area under the curve of IFN-γ, ESR, sIL-2R predicted the prognostic death of children with acute lymphoblastic leukemia were 0.867, 0.735, and 0.796, respectively. Conclusion: Children with acute lymphoblastic leukemia are mostly accompanied by high expression of serum IFN-γ and low expression of serum ESR and sIL-2R. All three of them are related to the immune phenotype and chromosome karyotype of the child, and are also the important factors for the prognosis of children. [ABSTRACT FROM AUTHOR]

Liver fibrosis is the common consequence of various chronic liver injuries and is mainly characterized by the imbalance between the production and degradation of extracellular matrix, which leads to the accumulation of interstitial collagen and other matrix components. Matrix metalloproteinases ( MMPs) and their specific inhibitors, i.e., tissue inhibitors of metalloproteinases ( TIMPs), play a crucial role in collagen synthesis and lysis. Through a literature review, this article reviews the experimental studies of liver fibrosis based on MMPs/ TIMPs, summarizes the components that may exert an anti - liver fibrosis effect by affecting the expression or activity of MMPs/TIMPs, and attempts to clarify the mechanism of MMPs/TIMPs in regulating collagen homeostasis, so as to provide support for the development of anti - liver fibrosis drugs.

Objective　To investigate the correlation of pulmonary function indexes and bronchial wall thickness measured as computed with high resolution computed tomography in patients with chronic obstructive pulmonary diseases. Methods　Eighty COPD patients were assigned to four groups based on the new COPD Global Initiative Classification, meanwhile，fifty normal people with physical examination in the hospital were selected as controls simultaneously. All subjects underwent chest HRCT scanning to measure the bronchial wall thickness at the bilateral apical bronchial opening，and the correlation between the bronchial wall thickness and lung function was studied. Results　Bronbronchial wall thickness was significantly increased in COPD patients compared with normal population，and the difference was statistically significant （ P < 0.05）. From the mild group to the very severe group， the bilateral bronchial wall thickness gradually increased，FEV1，FVC，FEV1/FVC gradually decreased，with statistically significant differences （ P < 0.05） . Correlation analysis： bilateral bronchial wall thickness was significantly inversely associated with each index of lung function （ P < 0.05）. Conclusions　HRCT can be used to measure bronchial wall thickness and evaluate the degree of bronchial wall remodeling in COPD patients. With the deepening of the disease grade，the thickness of the bronchial wall of COPD patients gradually increased. There is a significant correlation between lung function indexes and bronchial wall thickness，that is，the thickening of bronchial wall，the decline of lung function indexes and the deterioration of lung function. HRCT measurement of bronchial wall thickness in COPD patients has clinical significance for the evaluation of the severity of the disease. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To probe into the effects of Zishen Tiaochong method and growth hormone on outcome of in vitro fertilization and embryo transfer (IVF-ET) in women with diminished ovarian reserve (DOR) at different age. METHODS: Pregnancy outcomes of 217 patients with DOR undergoing IVF-ET in Guangdong Women and Children Hospital from Jan. 2017 to Jan. 2019 were analyzed retrospectively, including 105 patients < 35 years old and 112 patients ≥35 years old. All patients were on antagonist regimens and were on the first cycle of superovulation. In each age group, according to different pretreatment methods, all patients were divided into the traditional Chinese medicine group, the GH group and the control group. The traditional Chinese medicine group was given intervention of Zishen Tiaochong method, the GH group was pretreated with GH, and the control group was not pretreated with TCM or GH. Differences in clinical and laboratory indexes and pregnancy outcomes were observed in the three groups within the two age groups. RESULTS: There was no significant change in ovarian response and clinical outcome in patients with DOR aged <35 years old after GH intervention. The thickness of intrauterine membrane on the day of transplantation, number of harvested eggs and two prokaryotes (2PN) fertilization rate of the traditional Chinese medicine group were slightly higher than those of the GH group and the control group, but the difference was not statistically significant (P>0. 05). For patients with DOR aged ≥35 years old, the total application time and total dose of Gonadotropin (Gn) in the CH group were significantly lower than those in the traditional Chinese medicine group and the control group; the optimal embryo rate in the GH group was significantly higher than that in the traditional Chinese medicine group and the control group, with statistically significant difference (P<0. 05). Regardless of patients aged ≥35 years old or aged <35 years old, the endometrial thickness of patients in the traditional Chinese medicine group was the lowest during menstruation, which was significantly different from the GH group and the control group (P<0. 05). Within the two age groups, there was no statistically significant difference in the implantation rate, pregnancy rate and clinical pregnancy rate in the traditional Chinese medicine group, CH group and the control group, the difference was not statistically significant (P>0. 05). CONCLUSIONS: The intervention of GH in the elderly (≥35 years old) patients with DOR can improve the ovarian reactivity to a certain extent, while Zishen Tiaochong method is more effective in younger (< 35 years old) patients with DOR, and Zishen Tiaochong method can promote the endometrium spallation during menstruation and increase the endometrium thickness on the day of transplantation.
