Journal of Third Military Medical University 2003;0(15):-
Objective To explore the optimal condition for the differentiation of rat bone marrow mesenchymal stem cells (MSCs) into cardiomyocyte-like cells in vitro. Methods The MSCs were purified by percoll mediated density gradient centrifugation, and then randomly divided into A, B and C groups treated with 5, 10, 20 ?mol/L 5-azacytidine, respectively. MSCs in each group were treated with 5-azacytidine for 12, 24 and 48 h, and then cultured for 28 d before examination. The morphological changes in MSCs were observed with inverted microscope. The expression of ?-actin and cTnT was determined by immunohistochemistry and the protein expression of cTnT was determined by Western blotting. Results At day 28 after induction with 5-azacytidine, scattered myogenic structure was observed in the plasma of MSC under electronic microscope. Positive expression of ?-actin and cTnT were detected with immunohistochemistry. As compared with 10 ?mol/L (48 h) and 20 ?mol/L (12, 24 and 48 h) subgroups, there was no significant difference in the expression of cardiac troponin T among 5 ?mol/L (48 h) and 10 ?mol/L (24 h) groups without effect on the biological characteristics. Conclusion MSCs could be differentiated into cardiomyocyte-like cells by 5-azacytidine in vitro. Induction with 5 ?mol/L 5-azacytidine for 48 h or 10 ?mol/L of 5-azacytidine for 24 h is the optimal condition for the differentiation of MSCs into cardiomyocyte-like cells in vitro.

Objective To investigate the effect of electroacupuncture at point Zusanli (ST36) on gastric expression of heat shock protein 70 (HSP70) mRNA in rats with stress gastric ulcer and explore the molecular mechanism of its prevention and treatment of gastric ulcer. Method Fifty-one SD rats were randomly allocated to normal control (normal), stress gastric ulcer (model) and electroacupuncture at point Zusanli (electroacupuncture) groups. A model of stress gastric ulcer was made by cold restraint. From the second day after model making, the electroacupuncture group received electroacupuncture at point Zusanli 20 min once daily for three consecutive days, with left and right points Zusanli alternately needled; the model group, the same restraint treatment as in the electroacupuncture group; the normal group, no treatment. Gastric mucosal ulcer index (UI) was calculated using the GUTH’s method. The pathological morphology of gastric tissue was observed by HE staining. Gastric HSP70 mRNA expression was determined by RT-PCR. Result Different numbers and sizes of obvious gastric mucosal ulcers were observed, UI increased significantly (P<0.001) and HSP70 mRNA expression decreased significantly (P<0.05) in the model group compared with the normal group. The pathological change in gastric tissue improved somewhat, gastric mucosal UI decreased significantly (P<0.05) and HSP70 mRNA expression increased significantly (P<0.01) in the electroacupuncture group compared with the model group. Conclusion Electroacupuncture at point Zusanli can upregulate gastric HSP70 mRNA expression and promote the repair of gastric mucosa injuries in rats with stress gastric ulcer.

AIM: To study the effect of high fat diet on the expression of sterol regulatory element biding protein-1 (SREBP-1) and transforming growth factor β_1 (TGF-β_1) in renal tubular cells and rosiglitazone intervention. METHODS: Wistar rats were treated with high fat diet and rosiglitazone for 3 months. The serum glucose, serum insulin and serum triglyceride were detected. Oil Red O staining was used to observe the renal lipid deposit and Masson staining was for the detection of ECM accumulation. SREBP-1, TGF-β_1 and FN protein were determined by the methods of immunohistochemistry and Western blotting. SREBP-1 mRNA was detected by in situ hybridization. RESULTS: Rosiglitazone prevented effectively the increase in serum glucose, serum insulin and serum triglyceride resulted from high fat diet. High fat diet led to lipid droplet formation in renal tubular cells and interstitial ECM accumulation, which was decreased by rosiglitazone treatment. Compared to normal rats, SREBP-1 protein and SREBP-1 mRNA showed high expressions in high fat diet rats that were lowered by rosiglitazone. The precursor segment and mature segment of SREBP-1 protein were decreased by 27.39% and 27.32%. Similarly, the high expressions of TGF-β_1 and FN protein in kidney of high fat diet rats were also prevented by rosiglitazone intervention. Compared to high fat diet rats, the expression of TGF-β_1 in rosiglitazone treatment rats was lowered by 19.14%. CONCLUSION: Rosiglitazone prevents effectively the over-expression of SREBP-1 and TGF-β_1 in renal tubular cells, and decreases lipid accumulation and ECM production in rats fed with high fat diet.

The Chinese and English published literature regarding the effects of acupuncture on microcirculation in recent years were analyzed, and it was found out that the theory of TCM meridian had subtle connection with microcirculation on structure and function, which could provide a possible breakthrough for the research of meridian essence. Acupuncture, through multiple links, multiple paths and multiple levels, could regulate microcirculation under physiological or pathological condition, which was a bidirectional benign adjustment function, and reflected the characteristic of acupoint specificity. Due to many shortcomings in the current studies, studies with rigorous design, large sample size and multicenter are expected in the further to make a standard systematized research.

Objective:
To investigate the proportion of achieving the blood lipid control target and its influencing factors among residents at a high risk of atherosclerotic cardiovascular disease (ASCVD), so as to provide insights into management of blood lipid among residents at a high risk of ASCVD.
Methods:
Residents at a high risk of ASCVD and at ages of 35 to 70 years were sampled using a multi-stage cluster sampling method from 6 counties (districts) in Shaoxing City from May to July 2021. The residents' demographics, smoking, alcohol consumption and medical history of chronic diseases were collected using questionnaires, the height, weight, waist circumference (WC) and blood pressure were measured, and the total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and fasting blood glucose were detected. The proportion of blood lipids achieving the control target was analyzed, and factors affecting the proportion of blood lipids achieving the control target were identified using a multivariable logistic regression model.
Results:
A total of 1 695 individuals at a high risk of ASCVD were enrolled, including 940 men (55.46%) and 755 women (44.54%), with a mean age of (62.56±6.08) years. There were 285 participants that achieved the target of blood lipid control (16.81%). Multivariable logistic regression analysis identified gender (male, OR=1.962, 95%CI: 1.396-2.758), age (OR=1.037, 95%CI: 1.013-1.061), WC (OR=0.979, 95%CI: 0.964-0.995), diastolic blood pressure (OR=0.981, 95%CI: 0.967-0.994), smoking (OR=1.485, 95%CI: 1.034-2.133), alcohol consumption (OR=0.684, 95%CI: 0.498-0.941), hypertension (OR=1.428, 95%CI: 1.006-2.207), administration of hypoglycemic drugs (OR=2.326, 95%CI: 1.720-3.144) as factors affecting the achievement of the target for blood lipid control among residents at a high risk of ASCVD.
Conclusions
Individuals at a high risk of ASCVD with higher WC, higher diastolic blood pressure and alcohol consumption are less likely to achieve the target for blood lipid control, while male individuals with older age, hypertension and administration of hypogcemic drugs are more likely to achieve the target for blood lipid control.

To identify the cause of an outbreak of acute hemorrhagic conjunctivitis (AHC) in Jiangxi (China) in 2010, 20 eye conjunctival swabs were first collected from AHC patients. Then, viruses were isola- ted and tested for human enterovirus 70, coxsackievirus A24 variant (CV-A24v) and adenovirus using the polymerase chain reaction. All CV-A24v isolates underwent sequencing of 3C and VP1 coding regions. Then, a phylogenetic tree was constructed for Jiangxi CV-A24v and worldwide CV-A24v based on,3C and VP1 regions, respectively. Ten out of 20 specimens were positive for CV-A24v, implying that the outbreak was caused by CV-A24v. The phylogenetic tree based on the 3C region showed that Jiangxi CV- A24v belonged to cluster 5 in genotype IV (GIV-C5) with strains isolated throughout the world after 2010, and were divided further into A and B lineages. Phylogenetic analyses of the VP1 region showed that all of the worldwide CV-A24v strains isolated after 2000 could be divided into five groups (1-5). Jiangxi CV-A24v was classified into group 5 and also divided further into A and B lineages upon analyses of the 3C region. These data suggested that CV-A24v causing AHC outbreaks in China in 2010 belonged to GIV-C3 and GIV-C5. At least two transmission lineages were circulated in Jiangxi in 2010. The classification of CV-A24v isolated after 2010 worldwide using the phylogenetic tree based on the VP1 region was almost consistent with that based on the 3C region and also had significant chronological clustering.
