Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.

Objective: To explore the current situation of anxiety, subjective well-being in occupational population and the mediating effect of resilience. Methods: From March 24th to 26th, 2020, a cross-sectional survey was conducted among occupational population aged ≥18 years old using online questionnaires. A total of 2134 valid questionnaires were obtained, with respondents from 30 provinces, autonomous regions, and municipalities directly under the Central Government. Their general demographic data, subjective well-being, anxiety, and resilience were collected. Pearson χ(2) test and Spearson correlation analysis were used for data analysis, and structural equation model was used to explore the mediating effect of resilience on anxiety and subjective well-being. Results: The age of the respondents ranged from 18 to 60 years old, with an average age of (31.19±7.09) years old, including 1075 (50.4%) women and 1059 (49.6%) men. The positive rates of low subjective well-being and anxiety were 46.5% (992/2134) and 28.4% (607/2134), respectively. Anxiety scores were significantly negatively correlated with subjective well-being scores and resilience scores (r(s)=-0.52, -0.41, P<0.05), while resilience was significantly positively correlated with subjective well-being (r(s)=0.32, P<0.05). Structural equation models showed that anxiety had a negative predictive effect on subjective well-being, while resilience not only had a positive predictive effect on subjective well-being, but also played a mediating role between anxiety and subjective well-being, with a mediating effect of 9.9%. Conclusion: The situation of anxiety and well-being in the occupational population is still not optimistic, and resilience has a mediating effect between anxiety and subjective well-being.

Objective:To explore the effect of upregulating CXC-chemokine receptor 7 (CXCR7) in endothelial progenitor cells (EPCs) on angiogenesis after cerebral ischemia-reperfusion injury. Methods:EPCs were isolated and cultured from human umbilical cord blood and identified. Then, the EPCs were transfected with CXCR7 overexpression lentiviral vector, and the expression of CXCR7 was identified with real-time PCR and Western blotting. The tube-like structure formation and apoptosis of EPCs under oxidized low density lipoprotein (ox-LDL) were detected with tube-like structure formation test and Annexin V/PI staining. Cerebral ischemia-reperfusion injury model in rats was established, and the qualified model rats were randomly divided into three groups after 24 hours reperfusion: PBS group (n = 12) was injected with phosphate buffers through tail vein, control group (n = 12) was injected the EPCs infected with control lentiviral vector, and CXCR7 group (n = 12) was injected with EPCs infected with CXCR7 overexpression lentiviral vector. Neurological function scores were determined seven and 14 days after transplantation. The cerebral infarct volume was measured, the number of GFP-positive cells in the ischemic site and the density of capillary were observed. Results:The expression of CXCR7 in EPCs increased after transfection (P < 0.01). Overexpression of CXCR7 improved tube formation and reduced apoptosis of EPCs under ox-LDL (P < 0.05). Compared with PBS and control groups , neurological function improved in CXCR7 group, with less infarct volume, more GFP-positive cells and density of capillary (P < 0.05). Conclusion:Up-regulating CXCR7 can improve the survival and angiogenesis of EPCs, and improve the repair of cerebral ischemia-reperfusion injury.

OBJECTIVE: Evidence of the brain network involved in cognitive dysfunction has been inconsistent for major depressive disorder (MDD), especially during early stage of MDD. This study seeks to examine abnormal cognition connectivity network (CCN) in MDD within the whole brain. METHODS: Sixteen patients with MDD and 16 health controls were scanned during resting-state using 3.0 T functional magnetic resonance imaging (fMRI). All patients were first episode without any history of antidepressant treatment. Both the left and right dorsolateral prefrontal cortex (DLPFC) were used as individual seeds to identify CCN by the seed-target correlation analysis. Two sample t test was used to calculate between-group differences in CCN using fisher z-transformed correlation maps. RESULTS: The CCN was constructed by bilateral seed DLPFC in two groups separately. Depressed subjects exhibited significantly increased functional connectivity (FC) by left DLPFC in one cluster, overlapping middle frontal gyrus, BA7, BA43, precuneus, BA6, BA40, superior temporal gyrus, BA22, inferior parietal lobule, precentral gyrus, BA4 and cingulate gyrus in left cerebrum. Health controls did not show any cluster with significantly greater FC compared to depressed subjects in left DLPFC network. There was no significant difference of FC in right DLPFC network between depressed subjects and the health controls. CONCLUSION: There are differences in CCN during early stage of MDD, as identified by increased FCs among part of frontal gyrus, parietal cortex, cingulate cortex, and BA43, BA22, BA4 with left DLPFC. These brain areas might be involved in the underlying mechanisms of cognitive dysfunction in MDD.

Objective To observe the signal transducers and activator of transcriptions (STATs) protein expression changes and investigate the functional role of STATs pathway in case of high glucoseinduced cardiac fibroblasts (CFs) proliferation and collagen deposition in vitro.Methods Rat cardiac fibroblasts were isolated from 1-to 3-day-old SD rats,cells from the second to fourth passages were used for the experiment.CFs were cultured in Dulbecco's modified Eagle's medium,supplemented with 5.5 mmol/L glucose(NG),5.5 mmol/L glucose plus 19.4 mmol/L mannose(OC) or 25 mmol/L glucose(HG) in the presence of absence of STAT1 inhibitor (fludarabine,FLU) and STAT3 inhibitor (S3I-201).After 24 h and 48 h culture in vitro,the proliferation of CFs was measured by 3-(4,5-dimethyl-2 thiazoyl)-2,5-diphenyl2H-tetrazolium bromide (MTT) assay.After 12 h and 24 h culture in vitro,the production of type Ⅰ and Ⅲ collagen was evaluated using real-time quantitative PCR and ELISA.After 0,30,60 and 120 min culture in vitro,the phosphorylated expression of STAT1 and STAT3 was analyzed by Western blot.Results CFs proliferation was significantly enhanced post 24 h and 48 h HG stimulation,and procollagen Ⅰ and Ⅲ mRNA expression was significantly upregulated post 12 h and 24 h HG stimulation.Deposition of collagen Ⅰ and Ⅲ was also significantly increased post 24 h and 72 h HG stimulation.STAT1 phosphorylation in CFs was increased after 120 min HG stimulation and STAT3 phosphorylation in CFs was increased post 60 min and 120 min HG stimulation.FLU and S3I-201 could inhibit HG-induced CFs proliferation and suppress of which was stimulated by FLU and S3I-201 could both suppress upregulated procollagen Ⅰ and Ⅲ mRNA expression and the deposition of collagen types Ⅰ and Ⅲ post HG stimulation.STAT1 phosphorylation inhibition resulted in less mRNA downregulation of procollagen type Ⅱ than that of procollagen type Ⅰ post 12 h HG stimulation.The STAT3 phosphorylation inhibition resulted in more significantly upregulated procollagen type Ⅲ mRNA expression than procollagen type Ⅰ mRNA expression at 12 h post HG stimulation.Conclusion HG could enhance the protein expression of phosphorylated STAT1 and STAT3 in CFs,which are responsible for HG-induced increased CFs proliferation and collagen deposition in vitro.

Human infections with Lophomonas blattarum are rare. However, the majority of the infections occurred in China, 94.4% (136 cases) of all cases in the world. This infection is difficult to differentiate from other pulmonary infections with similar symptoms. Here we reported a case of L. blattarum infection confirmed by bronchoalveolar lavage fluid smear on the microscopic observations. The patient was a 21-year-old female college student. The previous case which occurred in Chongqing was 20 years ago. We briefly reviewed on this infection reported in the world during the recent 20 years. The epidemiological characteristics, possible diagnostic basis, and treatment of this disease is discussed in order to provide a better understanding of recognition, diagnosis, and treatment of L. blattarum infection.

OBJECTIVETo investigate the relationship between 8 endocrine-disrupting chemicals in the serum and insulin resistance in patients with polycystic ovary syndrome (PCOS).

METHODSThis study was conducted among 60 patients with PCOS, including 23 with insulin resistance (PCOS-IR) and 37 without insulin resistance (PCOS-NIR), and 29 non-PCOS women seeking medical attention for infertility or menstrual disorder (control group). The serum levels of 6 phthalic acid esters (PEAs), bisphenol A (BPA) and octylphenol (OP) were measured in all the subjects.

RESULTSThe levels of PAEs, BPA and OP showed no significant differences between PCOS patients and the control group (P>0.05). The serum level of OP was significantly lower in patients PCOS-IR than in those with PCOS-NIR (47.89 ng/ml vs 60.24 ng/ml, P<0.05).

CONCLUSIONPEAs and BPA do not produce obvious effect on the pathogenesis of PCOS or contribute to insulin resistance, but OP may play a role in insulin resistance in PCOS patients.
