BACKGROUND: Cardiac stem cells can differentiate into cardiomyocytes in vitro under induction of pilose antlerpolypeptides, which provides a new therapeutic idea for myocardial injury.OBJECTIVE: To explore the effect of pilose antler polypeptides on the apoptosis rate and membrane stability ofmitochondria in cardiac stem cells.METHODS: We chose healthy male Wistar rats born 2 days to extract cardiac stem cells. The culture dish was used asthe experimental unit, and extracted cells were divided into the following four groups (n=12). Blank control group: Thesame amount of buffer was added for induction; 5-azacytidine group: induced with 5-azacytidine (3 μmol/L); pilose antlerpolypeptides group: induced with pilose antler polypeptides (800 mg/L); combined group: induced with pilose antlerpolypeptides (800 mg/L) and 5-azacytidine (3 μmol/L). After 48 hours induction, apoptosis rate of cardiac stem cells ineach group was detected with flow cytometry. The membrane potential of mitochondria in cardiac stem cells wasdetected with immunofluorescence. The expression level of Nkx 2.5, GATA4, ATF-2, and MEF-2C in cardiac stem cellswas detected using western blot assay.RESULTS AND CONCLUSION: There were small, round and bright cells after 2 weeks culture, and cell colonies ofcardiac stem cells formed. The apoptosis rate of cardiac stem cells in the 5-azacytidine group increased significantly (P <0.05) and its membrane potential decreased significantly compared with the blank control group (P < 0.05). Theapoptosis rate of cardiac stem cells in the pilose antler polypeptides group and combined group decreased significantlycompared with the 5-azacytidine group (P < 0.05, P < 0.01), and their membrane potential increased significantly (P <0.05, P < 0.01). The results of western blot showed that the expression level of Nkx2.5 increased significantly in thepilose antler polypeptides group and combined group compared with the 5-azacytidine group (P < 0.05), while theexpression levels of GATA4 and ATF-2 in each group were low and there were no significant differences among groups(P > 0.05). The expression level of MEF-2C in each group was at a middle level, and there were no significantdifferences among groups (P > 0.05). To conclude, our experimental findings indicate that pilose antler polypeptidescould decrease the apoptosis rate and improve membrane stability of mitochondria in cardiac stem cells. Themechanism may be related to the increased expression of Nkx 2.5, but whether the mechanism is related to GATA4,ATF-2 and MEF-2C needs to be further studied.

ObjectiveTo investigate the relationship between the social disability and emotion disorder of the patients with irritable bowel syndrome (IBS). Methods168 patients with IBS were assessed with Social Disability Screening Schedule (SDSS), Hamilton Anxiety Rating Scale, and Hamilton Depression Rating Scale. The patients with SDSS≥2 were divided into 2 groups, and accepted the medical routine therapy and explanatory psychotherapy for 2 months, while the patients in the research group (n=35) received the antidepressive. Then they were assessed with SDSS again. ResultsThe incidence of social disability in IBS patients was 40.5%, and increased in those who combined with anxiety and/or depression. The SDSS score of the research group was lower than that of the control group after the treatment. ConclusionThe social disability can be found in the patients of IBS, especially in those with emotion disorder, and can be improved by the antidepressive.

Objective To further clarify the pathogenesis of different types of Kaposi′s sarcoma (KS) by measuring the protein expressions of caspase-3 and E-cad in tumor tissues of Xinjiang Uygur patients with acqured immunodeficiency syndrome (AIDS)-Kaposi′s sarcoma (KS) and classical KS.Methods From July 2011 to October 2014, 38 patients with KS at the First Affiliated Hospital of Xinjiang Medical University and Urumqi Infectious Disease Hospital were enrolled, among whom 28 were male and 10 were female, and all of them were uygur.Immunohistochemical and Western blot methods were used to detect the expressions of caspase-3 and E-cad proteins in 22 cases of AIDS-KS patients and 16 cases of classic KS.The quantitative data of normal distribution were analyzed by t test, while count data were compared with χ2 test with R × C table.Results KS lesions in patients with classic KS were confined to the skin, without mucosal, lymph node or visceral involvement.Lesions in AIDS-KS patients were not only confined to the skin and superficial lymph nodes, but also oral mucosa involved in 12 cases and internal organs involved in 7 cases.Liver and lung involvement was more common.The CD4+T lymphocyte count in patients with AIDS-KS was (200.8±166)/μL.All 15 AIDS cases with CD4+ T cell count less than 200/μL developed opportunistic infections.CD4+ T lymphocyte count of patients with classic KS was (562.52±222.66)/μL and the 16 patients with CD4+T lymphocyte count greater than 350/μL had no opportunistic infections.The results of immunohistochemistry showed that the positive expression rate of caspase-3 protein in KS tissues in patients with AIDS-KS was 68.2%, in patients with classic KS was 100.0%, with significant difference between two groups (χ2=7.37, P=0.01).The positive expression rate of E-cad protein in KS tissues in patients with AIDS-KS was 72.7%, in patients with classic KS was 100.0%, with significant difference between two groups (χ2=5.18, P=0.03).Western blotting showed that the gray value of caspase-3 in the KS tissue of patients with AIDS-KS was 0.55±0.36, and that in patients with classic KS was 0.86±0.56, with significant difference between two groups (t=-2.070, P<0.05).The gray value of E-cad in the KS tissue of patients with AIDS-KS was 0.54±0.41, and that in patients with classic KS was 0.85±0.45, with significant difference between two groups (t=-2.060,P<0.05).Conclusions There are differences in the protein expressions of caspase-3 and E-cad in tumor tissues of patients with AIDS-KS and classical KS in Xinjiang Uygur patients with Kaposi's sarcoma, which may correlate with a faster progression and a higher mortality rate for AIDS-KS.

Objective To compare the traditional electrophysiological testing with modified methods for differential diagnosis of Radial Tunnel Syndrome (RTS).Methods A total of 87 selected patients were initially diagnosed as Lateral Epicondylitis (LE) or Tennis Elbow (TE) by doctors from the Outpatient Department of Orthopedics and Rehabilitation.Medical history was asked.Patients received physical examination and examinations for the sensory nerve action potential (SNAP) of superficial radial nerve,the compound muscle action potential (CMAP) of radial nerve and needle electromyography (EMG) to record the muscle Motor Unit Action Potentials (MUAPs).Then,the modified methods for CMAP of radial nerve were conducted on the forearm in the neutral,pronation and supination positions.Three values of CMAP latency were compared.RTS was diagnosed when the difference value ≥0.3 ms.The x 2 test was used to compare the positive detectable rates of the two methods for the RTS diagnosis.Results Thirteen out of 87 patients were diagnosed as RTS,among which three had interosseous nerve lesion and one had superficial radial nerve lesion.The traditional EMG failed to diagnose the remaining 9 RTS cases.These patients were finally diagnosed due to their latency difference of radial nerve CMAP ≥0.3ms when their forearms were examined in three positions.Conclusion The modified electrophysiology method shows a higher positive rate for the diagnosis of RTS.(P＜0.05).

Objectives To enhance the diagnosis of cervical epithelial neoplasia and cervical cancer at the early stage and to prevent cervical invasive carcinoma by analyzing the cervical/vaginal cytology or histopathologic results of Atypical squamous cells of undetermined significance (ASCUS).Methods From January 2014 to June 2015,a total of 4579 cases were selected in the census of gynecological diseases in Qiannan Hospital.TBS classification (the bethesda system) showed that 164 cases of ASCUS or above were found using cervical/vaginal cytology with live tissue under colposcopy.Results Among 164 cases,75 was cervical intraepithelial neoplasia level 3 (CINⅢ) accounting for 54.7％.Sixty-three cases of ASCUS and 16 of CINⅡ or above were found among patients at the age of 39 or younger (25.4％).A hundred and one cases of ASCUS and 59 of CINⅡ or above were found among women older than 40 (58.41％).Among patients with liquid-based cervical cytology positive,those older than 40 had higher risk.Liquid-based cervical cytology examination was divided into 5 levels.Spearman rank correlation analysis was applied with correlation coefficient (r =1) and positive correlation was shown (P =0.000,P＜0.01).The difference was statistically significant.The higher level of liquid-based cervical cytology examination level was required,the higher risk of cervical cancer was seen among women.Corclusion The use of liquid-based cervical cytology examination can help grassroots doctors improve CIN diagnosis rate and prevent cervical invasive carcinoma among women in the countryside.
