OBJECTIVETo investigate the effect of Busheng Huoxue Capsule (BHC) on the quality of life (QOL) in senile male osteoporosis (OP) patients, and to explore its mechanisms.

METHODSTotally 200 senile primary OP patients were randomly assigned to two groups according to random digit table method, 100 in each group. Patients in the treatment group took BHC plus caltrate-D (600 mg CaCO3), while those in the control group took alendronate (70 mg per week) plus caltrate-D. The therapeutic course was 12 months for all. Chinese medical symptom score and quality of life (QUALEFFO-41) score, bone mineral density (BMD) of lumbar vertebra (L2 -L4) and left femoral neck were compared between the two groups before and after treatment. Serum free testosterone (FT) and estradiol (E2) were also measured.

RESULTSChinese medical symptom scores and QUALEFFO-41 scores, serum FT and E2 levels increased in the two groups after treatment (P < 0.05, P < 0.01). The therapeutic effect was superior in the treatment group (P < 0.05, P < 0.01). After treatment the BMD of lumbar vertebra (L2 -L4) and the left femoral neck were somewhat improved (P < 0.05), but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONBHC could effectively improve the QOL of senile male OP patients, which might be correlated with elevating the BMD levels and regulating the levels of sex hormones.

Objective To further prove the multipotentiality of rabbit bone mesenchymal stem cells (MSCs) by inducing it into cardiomyocytes with 5-azacytidine. Methods MSCs from rabbit were abstracted, isolated, cultured. Then MSCs were induced by 5-azacytidine in vitro for 24 hours. After cultured for 4 weeks, MSCs’ differentiation was studied by immunohistochemistry and electron microscopy technique. Results Some of MSCs induced by 5-azacytidine expressed troponinT . Electron microscopy showed myofilaments. Conclusion MSCs which exist in bone marrow are mutipotential stem cells, and they can be induced into cardiomyocytes by 5-azacytidine in vitro.

BACKGROUND: It was uncertain that the migration, differentiation and survival of transplanted bone marrow mesenchymal stem cells (BMSCs) into myocardium after the acute myocardial infarction. OBJECTIVE: To investigate the migration, differentiation and survival of rabbit transplanted autologous BMSCs in myocardium after the acute myocardial infarction. METHODS: Rabbit BMSCs were isolated and labeled by DAPI in vitro. Rabbit left anterior descending branch was ligated to establish acute myocardial infarction models. Following successful model establishment, 30 New Zealand rabbits were assigned to BMSC and control groups (n = 15). In the BMSC group, autologous BMSCs were infused into the surrounding sites of the infracted region by 4 points 1 hour following coronary artery ligation. In the control group, the same region was injected with an equal volume of saline. Injection volume was 30 μL in each point. Five animals from each group were sacrificed 10 minutes, 3 days and 4 weeks following transplantation. The heart was obtained to undergo frozen sections. The distribution of DAPI-labeled BMSCs was observed using fluorescence microscope. Immunofluorescence method was used to examine the troponin Ⅰ and α-actin. RESULTS AND CONCLUSION: DAPI-labeled BMSCs with blue nuclei were distributed extensively in the myocardium of the cell transplantation group, ovoid in shape and arranged in parallel with the cardiac muscle fibers. Troponin Ⅰ and α-actin were positive immunofluorescently in the cytoplasm of the labeled BMSCs. Results indicated that transplanted BMSCs in the ischemic myocardium could differentiate into myocardial cells under stimulation of local microenvironment.

Objective To investigate the effects of CD4+CD25high regulatory T cells(Treg)and the imbalance of helper T lymphocyte subsets(Th1/Th2)on the immunological mechanism of IgA nephropathy(IgAN)patients. Methods The percentage of Treg and helper T cells subpopulation (Th1/Th2)in the peripheral blood of IgAN patients and healthy controls was examined by flow cytometry.The FOXP3 expression was detected through intracellular staining.The correlation of Treg or Th1/Th2 with clinical parameters of IgAN was analyzed by Spearman or Pearson rank correlation test. Results The percentages of Treg and Th2 cells were significantly higher in peripheral blood of IgAN patients compared to that of healthy controls[Treg (2.14±0.82)%vs[1.59±0.53)%,Th2(2.57±0.72)%vs(1.81±1.10)%,all P＜0.05].Th1/Th2 ratio was significantly reduced in IgAN patients(5.75±1.89 vs 12.73±9.79,P＜0.05).The percentage of circulating Treg cells was positively correlated with serunl IgA concentration(r=0.397,P＜0.05),and was negatively correlated with eGFR(r=-0.376,P＜0.05).The percentage of circulating Th2 cells was positively correlated with serum IgA(r=0.468,P＜0.05). Conclusions There is a disorder of T lymphocyte population in the peripheral blood of IgAN patients.The increased Treg and Th2 cells may play an important role in the pathogenesis of IgAN.

Abstract: Objective　To analyze the survival status of HIV/AIDS patients aged above 50 years receiving antiviral therapy (ART) in Shanxi Province from 2011 to 2019, and to provide evidence for further improvement of antiviral therapy. Methods　Basic information and follow-up information of HIV/AIDS patients aged above 50 years who first received HIV/AIDS antiviral therapy in Shanxi Province from 2011 to 2019 were collected. Excel database was established and SPSS23.0 software was used for analysis. Retrospective cohort study was conducted. Cox proportional risk regression model was used to analyze the factors influencing survival time. Results　A total of 1 183 subjects were included, of which 172 died, including 84(48.84%) from other causes, 74(43.02%) AIDS-related death and 14 (8.14%) from accidents, suicides and undetermined deaths. Setting AIDS-related deaths as an outcome event, life table analysis showed that the cumulative survival rates at 1, 3, 5, 7 and 9 years after receiving ART were 96.61%, 93.59%, 90.35%, 87.57% and 83.44%, respectively. Multivariate Cox proportional risk model analysis showed that the risk of death in patients aged 60-<70 years group and over 70 age group was 2.53 times (95%CI: 1.51-4.23) and 3.59 times (95%CI: 1.74-7.40) for patients aged the 50-<60 group , respectively. The risk of death in patients with baseline CD4+T lymphocyte (CD4) counts of ≥200/mm3, 50-<200 /mm3 was 0.22 times (95%CI: 0.12-0.41) and 0.37 times (95%CI: 0.21-0.67) for patients with CD4+T lymphocyte counts of <50/mm3. The risk of death in patients with opportunistic infections at baseline was 1.99 times (95%CI: 1.16-3.39) for patients without baseline opportunistic infections. Conclusions　The survival rate of HIV/AIDS patients aged above 50 who received antiviral therapy (ART) in Shanxi Province from 2011 to 2019 was relatively high. To further improve the quality of antiviral treatment in our province, the strategy of "early detection and early treatment" should be continued and improved in the future, and information collection of specific causes of non-AIDS-related deaths among this population should be further strengthened.

BACKGROUNDStent thrombosis is one of severe complications after sirolimus-eluting stent implantation. Rapamycin (sirolimus) promotes arterial thrombosis in in vivo studies. However, the underlying molecular and transcriptional mechanisms of this adverse effect have not been thoroughly investigated. This study was designed to examine the effects of rapamycin on the expression of the gene, Kruppel-like factor 2 (KLF2), and its transcriptional targets in mice.

METHODSMice were randomly divided into four groups: the control group (intraperitoneal injection with 2.5% of dimethyl sulfoxide (DMSO) only), rapamycin group (intraperitoneal injection with 2 mg/kg of rapamycin only), Ad-LacZ + rapamycin group (carotid arterial incubation with Ad-LacZ plus intraperitoneal injection with 2 mg/kg of rapamycin 10 days later), and Ad-KLF2 + rapamycin group (carotid arterial incubation with Ad-KLF2 plus intraperitoneal injection with 2 mg/kg rapamycin 10 days later). The carotid arterial thrombosis formation was induced by FeCl3 and the time of arterial thrombosis was determined. Finally, the RNA and protein of carotid arteries were extracted for KLF2, tissue factor (TF), plasminogen activator inhibitor-1 (PAI-1), endothelial nitric oxide synthase (eNOS), thrombomodulin (TM) mRNA and protein analysis.

RESULTSCompared with controls, treatment with rapamycin inhibited KLF2, eNOS and TM mRNA and protein expression, and enhanced TF and PAI-1 mRNA and protein expression, and shortened time to thrombotic occlusion from (1282 ± 347) seconds to (715 ± 120) seconds (P < 0.01) in vivo. Overexpression of KLF2 strongly reversed rapamycin-induced effects on KLF2, eNOS, TM, TF and PAI-1 expression. KLF2 overexpression increased the time to thrombotic occlusion to control levels in vivo.

CONCLUSIONSRapamycin induced an inhibition of KLF2 expression and an imbalance of anti- and pro-thrombotic gene expression, which promoted arterial thrombosis in vivo. Overexpression of KLF2 increased KLF2 expression and reversed time to thrombosis in vivo.

BACKGROUNDAirway symptoms in asthma are related to decrease of epinephrine secretion, which may be ascribed to elevated nerve growth factor (NGF) in the organism. The aim of this study was to monitor the neuroendocrine alteration in the adrenal medulla of asthmatic rats.

METHODSSixteen rats were randomly divided into two groups (n = 8), control group and asthma group, and the asthmatic rats were sensitized and challenged with ovalbumin (OVA). The levels of NGF, epinephrine and norepinephrine in serum were detected by enzyme linked immunosorbent assay (ELISA), the NGF expression in adrenal medulla was detected by immunohistochemistry, and the changes in the ultrastructure of the adrenal medulla was observed by electron microscopy.

RESULTSThe NGF expression was increased in asthmatic rats compared with control rats. Compared with control rats, the results indicated that the epinephrine level was decreased in asthmatic rats, but no significant difference was found in norepinephrine levels. We found more ganglion cells in the adrenal medulla of asthmatic rats than in control rats, with NGF immunostaining mainly located in these ganglion cells. Electron microscopic images showed the density of chromaffin granula decreased and there was shrunken nucleolemma in the adrenal medullary cells of asthmatic rats.

CONCLUSIONThe innervation of the adrenal medulla is changed in asthmatic rats, and it may contribute to the epinephrine decrease in asthma.
