Objective To observe the effect of transcranial low frequency electrical stimulation on the contents of monoamines in ischemic area of rats with middle cerebral artery occlusion(MCAO).MethodsPermanent MCAO model of Wistar rat was established with silk thread enveloped with polyammoniacum.The ischemic areas received various intensity of transcranial low frequency electrical stimulation for 1 hour in rats underwent 1 hour of ischemia.Then the affected tissue was processed with fluorospectrophotometry to determine the contents of dopamine(DA),noradrenalin(NE) and 5-hydroxytryptamine(5-HT).ResultsCompared with the sham-operation group,the contents of DA,NE and 5-HT in ischemic area of MCAO model rats decreased obviously(all P<0.01),while all three monoamines investigated in the sham-operation group with transcranial low frequency electrical stimulation had no significant change.In the MCAO groups stimulating with lower(10 V) and middle(30 V) intensity transcranial low frequency electrical field,the contents of DA,NE and 5-HT in ischemic area had no significant increase.But in the MCAO group stimulating with high(50 V) intensity transcranial low frequency electrical field,the contents of DA,NE and 5-HT in ischemic area increased significantly(P<0.05).ConclusionSome degree of intensity transcranial low frequency electrical field stimulation can increase the contents of DA,NE and 5-HT in ischemic area of rats subjected to MCAO.

Rheumatoid arthritis ( RA) is a chronic inflammatory disease involving progressive articular damage cause by inflam-matory cells and synoviocytes.Stat3 gene, which is confirmed to play a role in the pathogenesis of RA, regulates the metabolism and apoptosis of the fibroblast-like synoviocytes ( FLS) .SirT1 gene relating to the bone formation was indicated to play a role in the patho-genesis of RA in recent years.This review introduces the pathogenesis and targeted treatment of RA and makes a prediction about the relation between Stat3 and SirT1 gene.We hope it will provide a new direction for the research of RA.

Objective To study the effects of tetrandrine on apoptosis of HeLa cervical cancer cells qualitatively and quantitatively. Methods We measured tetrandrine-induced inhibition of HeLa cell proliferation at different concentrations and time points by MTT assay. The rate of Hela cell apoptosis induced by tetrandrine was detected by flow cytometer and confocal laser scanning microscope (CLSM). Results Tetrandrine inhibited the proliferation of HeLa cells in dosage- and time-dependent manners. Flow cytometry showed that the apoptosis rate was (51.8±0.97)% at the concentration of 15μmol/L, which was significantly higher than that in the control group (24.3±1.23)% (P<0.05). The cells treated with tetrandrine showed typical apoptotic morphology under CLSM. Conclusion Tetrandrine can inhibit proliferation and induce apoptosis of HeLa cervical cancer cells.

Objective To investigate the pathological types and features of lymph nodes in human immunodeficiency virus(HIV)/acquired immune deficiency syndrome(AIDS)patients with superficial lymphadenectasis.Methods The tissues of lymph nodes were obtained from 151 HIV/AIDS patients with superficial lymphadenectasis for pathological examination.The pathological results were observed by light microscope after Hematoxylin-Eosin(HE),acid-fast,periodic acid-Schiff (PAS),and digested-PAS(D-PAS)staining.The pathological results of lymph nodes were described and the correlation between pathological changes and CD4+T lymphocyte count was analyzed.Chisquare test was used for the statistic analysis.Results The benign lesions were found in 145 patients (96.0%),while the malignant tumors were found in 6 patients(4.0%).The pathological findings in the 151 HIV/AIDS patients included tuberculosis(72 patients),lymph node reactive hyperplasia(34patients),lymphatic fungal infections(23 patients,including penicillium diseases in 19 cases),AIDSrelated lymphadenectasis(14 cases),non-Hodgkin lymphoma(5 cases),benign fibrous histiocytoma (1 case).In addition,there were 83 patients(55.0%)with CD4+T lymphocyte count lower than 100×106/L.The frequency of penicillium diseases was higher in patients with lower CD4+T lymphocyte count(x2=7.757,P=0.021).Conclusions The major reasons for superficial lymphadenectasis in HIV/AIDS patients are infectious diseases,such as tuberculosis and fungal infections,which are common in patients with lower CD4+T lymphocyte counts.Non-Hodgkin lymphoma is the most common malignant tumor in this patient population.

Objective To investigate the problem of adverse effects in common AIDS patients and AIDS patients with tuberculosis after highly active antiretroviral therapy (HAART). Methods The case group was composed of 106 patients with both AIDS and tuberculosis. The control group was composed of 134 common AIDS patients. The rates of adverse effects and the increase of CD4 + T cell count in those groups after first year HAART were observed and compared. Results The rates of adverse effects in the case group was 36. 8% ,which was more than that in the control group (26. 9%), but the difference was not significantly different(x2 =2.715, P =0. 099). The count of CD4+ T cell in most of the patients was increased after HAART (P ＜ 0. 01). The increase of CD4 + T cell count in the case group [(147.2 ±137.6)/μl] was higher that in the control group[(142. 1 ± 127. 0)/μl after six months HAART vs. (166. 5±133. 1)/μl in case group], and it was lower than that in control group after nine months HAART [(172.7±107.5)/μl], however the difference was not significant(P ＞0.05). Conclusions HAARTcould reconstruct the immunition of AIDS patients. The increase of CD4 + T cell count did not show significant difference between common AIDS patients and AIDS patients with tuberculosis after HAART. AIDS patients with tuberculosis might not increase the risk of development of adverse effects during HAART.

Objective To investigate the expression and clinical significance of CD28 and CD160 in patients with chronic HIV infection.Methods 50 patients with HIV from January 2016 to January 2017 were selected as the observation group, and 50 healthy volunteers were recruited as control group.Observe and record general information of all participants, the expression of CD28, CD160 in CD4+and CD8+T cells, initial T cells (TN), the expression of CD160 in central memory T cells (TCM), effector memory T cells (TEM), end effector memory T cells (TEMRA), mean fluorescence intensity (MFI), viral load of two kinds of the cells, analyze the correlation between the expression level of CD28 and CD160 and CD4+T cell count and viral load.Results With the increase of CD160 expression of CD4+T cells, CD4+T cells showed a downward trend, there is a negative correlation between them (r=-0.561, P＜0.05), CD8+T cell number is on the rise, there is a positive correlation between them (r=0.619, P＜0.05), and HIV-RNA copy number increased with the increase of CD160 expression on CD4+T cells and CD8+T cells, both positive (r=0.684, P＜0.05, r=0.459, P＜0.05);with the increase of CD28 cells on the expression of CD4+T, CD4+, CD8+T cells showed a rising trend, there is a positive correlation between them (r=0.621, P＜0.05, r=0.527, P＜0.05, HIV-RNA) and the copy number decreased with the increase of the expression of CD28 and CD4+T on CD8+T cells, there is a negative correlation between them (r=-0.634, P＜0.05, r=-0.582, P＜0.05).There was no significant difference in the positive rate of expression in TEMRA subgroup and MFI of CD160 in CD8+T cell in two groups (P＞0.05).The positive rate and MFI of CD8+T cell CD160 in TN, TCM and TEM subgroups in observation group were significantly higher than those in control group (Tcm), with statistical significance.Conclusion The expression of CD28 in patients with chronic HIV infection is decreased, and the expression of CD160 is increased, which may be related to the decrease of HIV CD4+T and CD8+T cells, in which CD160 mainly affects the memory CD8+T.

Objective To investigate the expression of arginase Ⅰ (.Arg Ⅰ) in peripheral superficial lymph nodes of HIV-infected individuals and to explore their correlation with HIV/AIDS disease progression.Methods All the patients were divided to two groups according to the CD4 + T cell counts in peripheral blood,immunohistochemistry was used to detect expression of Arg Ⅰ in peripheral superficial lymph node of non HIV-infected and HIV-infected individuals.The data were statistically analyzed with SPSS17.0.Results Levels of Arg Ⅰ expression in peripheral superficial lymph node of HIV-infected individuals were higher than those of non HIV-infected lymph nodes (P ＜ 0.01).The expressions of Arg Ⅰ in patients with AIDS in different CD4 + T lymphocyte counts were distinct.Levels of Arg Ⅰ expression in peripheral superficial lymph nodes of CD4 + T lymphocyte counts ≥350/ μl and 200/ μl ≤ CD4 + T lymphocyte counts ＜ 350/ μl AIDS patients had no significant difference (P ＞ 0.05),while there was significant difference between expression of Arg Ⅰ in CD4 + T lymphocyte counts ≥ 350/ μl,200/ μl ≤ CD4 + T lymphocyte counts ＜ 350/ μl and CD4 + T lymphocyte counts ＜ 200/ μl AIDS patients (P ＜ 0.05).In addition,statistical analysis of the above results showed that CD4 +T cell counts in peripheral blood were negatively correlated with expression level of Arg Ⅰ.Conclusions Levels of Arg Ⅰ expression in peripheral superficial lymph node of AIDS patients were significantly high and associated with disease progression.

Objective:To analyze the time point when patients with fatty liver disease had a significantly higher risk of elevated fasting blood glucose than those without in the physical examination group in Karamay Central Hospital, factors affecting the incidence of elevated blood glucose in patients with fatty liver disease, and the influence of the number of influencing factors on it.Methods:Physical examination data from Karamay Central Hospital during September 2008 to April 2017 were retrospectively analyzed. Combined with the survival analysis, the 1-,3-, 5-, and 7-year prevalence rates of elevated fasting glucose occurs in people with and without fatty liver disease were analyzed. Z-test was used to compare the survival rate difference at each time point. Cox regression model was used for multivariate analysis.Results:10 802 people were in the fatty liver group. The elevated fasting blood glucose incidence density was 61/1 000 person-years, and the 1-, 3-, 5-, and 7-year prevalence rates were 2%, 16%, 28%, and 38%, respectively. 29 579 people were in the non-fatty liver group. The elevated fasting blood glucose incidence density was 23/1000 person-years, and the 1-, 3-, 5-, and 7-year prevalence rates were 1%, 7%, 11%, and 16%, respectively. The short-term and long-term elevated fasting blood glucose incidence risk were significantly higher in fatty liver group than non-fatty liver group( P < 0.001). The elevated fasting blood glucose incidence risk was apparently higher in fatty liver group than that of non-fatty liver group from the first year onward ( P < 0.001). Age≥50 year’s old ( HR = 1.954, 95% CI :1.792-2.132), elevated body mass index ( HR = 1.397, 95% CI : 1.198-1.629), blood pressure ( HR = 1.284, 95% CI : 1.181-1.397), triglycerides ( HR = 1.171, 95% CI: 1.077-1.274) were independent risk factors, which promoted the elevated fasting blood glucose incidence risk in patients with fatty liver disease. Fatty liver combined with the above 2, 3, and 4 risk factors had apparently increased the incidence risk of elevated fasting blood glucose ( P < 0.001). Conclusion:People with fatty liver disease had a higher risk of elevated fasting blood glucose from the first year than those without. Age≥50 year’s old, elevated blood pressure, body mass index and triglyceride might increase risk of elevated fasting blood glucose in patients with fatty liver disease, combined with the above 2,3 or 4 risk factors can increase the risk of elevated fasting blood glucose.

Objective To investigate the effects of software follow-up mode application on stigma sense,social function and survival quality in the patients with schizophrenia.Methods A total of 100 inpa-tients with schizophrenia in the psychiatric department of this hospital from January to December 2023 were selected as the study subjects and divided into the observation group(software follow-up)and the control group(telephone follow-up)according to different follow-up modes,50 cases in each group.At discharge from hospital and in 4,8,12 weeks after discharge,the Chinese version of Stigma Scale for Mental illness(SSMI-C)was adopted to evaluate the stigma sense of the patients,the Social Disability Screening Schedule(SDSS)was used to evaluate the patients'social function,the patients'survival quality was evaluated by the Generic Qual-ity of Life Inventory-74(GQOLI-74).The changes of above scores were compared between the two groups.Results The SSMI-C,SDSS and GQOLI-74 scores at discharge from hospital had no statistical difference be-tween the two groups(P＞0.05).Compared with at discharge from hospital,the SSMI-C and SDSS scores in 4,8,12 weeks of follow up in the two groups were decreased,the GQOLI-74 score was increased,moreover the scores of SSMI-c and SDSS in the observation group were lower than those in the control group,the GQOLI-74 score was higher than that in the control group,and the differences were statistically significant(P＜0.05).Conclusion Conducting the regular follow-up on discharged patients with schizophrenia by the follow-up soft-ware could reduce the stigma of the patients,improve the social functional defect and improve the survival quality.
