Lysosomal membrane protein Sidt2 knockout induces apoptosis of human hepatocytes in vitro independent of the autophagy-lysosomal pathway / 南方医科大学学报

OBJECTIVE@#To explore the regulatory mechanism of human hepatocyte apoptosis induced by lysosomal membrane protein Sidt2 knockout.@*METHODS@#The Sidt2 knockout (Sidt2-/-) cell model was constructed in human hepatocyte HL7702 cells using Crispr-Cas9 technology.The protein levels of Sidt2 and key autophagy proteins LC3-II/I and P62 in the cell model were detected using Western blotting, and the formation of autophagosomes was observed with MDC staining.EdU incorporation assay and flow cytometry were performed to observe the effect of Sidt2 knockout on cell proliferation and apoptosis.The effect of chloroquine at the saturating concentration on autophagic flux, proliferation and apoptosis of Sidt2 knockout cells were observed.@*RESULTS@#Sidt2-/- HL7702 cells were successfully constructed.Sidt2 knockout significantly inhibited the proliferation and increased apoptosis of the cells, causing also increased protein expressions of LC3-II/I and P62(P < 0.05) and increased number of autophagosomes.Autophagy of the cells reached a saturated state following treatment with 50 μmol/L chloroquine, and at this concentration, chloroquine significantly increased the expressions of LC3B and P62 in Sidt2-/- HL7702 cells.@*CONCLUSION@#Sidt2 gene knockout causes dysregulation of the autophagy pathway and induces apoptosis of HL7702 cells, and the latter effect is not mediated by inhibiting the autophagy-lysosomal pathway.

Clinical efficacy and anti-inflammation/anti-fibrosis effect of tripterygium glycosides in the treatment of diabetic nephropathy / 中国临床药理学与治疗学

AIM: To observe the clinical efficacy of multi -glycoside of tripterygium wilfordii (GTW) on diabetic nephropathy. METHODS: Fifty-one patients with diabetic kidney disease (DKD) with a history of GTW dosing admitted to the outpatient clinic of Yijishan Hospital affiliated to Wannan Medical College from June 2019 to October 2022 were selected as study subjects, and were followed up regularly to observe the changes in laboratory indexes before and after GTW dosing and adverse drug reactions after 6 months of treatment. The t-test, Mann-Whitney U-test or χ

Retrospectively analysis of the effect of low-dose aspirin on primary prevention of non-fatal myocardial infarction and cerebral infarction in patients with type 2 diabetes mellitus / 中国临床药理学与治疗学

AIM: To investigate the effect of low-dose aspirin on primary prevention of non-fatal myocardial and cerebral infarction in patients with type 2 diabetes mellitus. METHODS: From January 2015 to December 2016,40-90 years old patients with type 2 diabetes were treated in the Department of Endocrinology of Yijishan Hospital of Wannan Medical College for more than 2 times (the interval of hospitalization was more than 3 months) , we use the hospital's his system to search out-patient and in-patient files, patients were divided into aspirin group and non-aspirin group according to the use of low-dose aspirin within 1 year after the first visit, the basic data of the first visit were collected: name, sex, age, course of diabetes, systolic and diastolic blood pressure, patients were recorded for laboratory markers including fasting blood glucose, glycated hemoglobin, triglyceride, total cholesterol, Low-density lipoprotein, high-density lipoprotein, creatinine, and platelets, complications such as hypertension, coronary heart disease, atrial fibrillation, hyperlipidemia, diabetic nephropathy and arteriosclerosis were recorded. A Chi square test and a Cox proportional hazard model were used to compare baseline data and cerebrovascular disease after the first use of aspirin. RESULTS: Of the 4 176 patients, 2 137 were type 2 diabetes, 417 were eligible for admission, including 198 males, 219 females, 224 aspirin users and 193 non-users. There was no significant difference in the incidence of cerebral infarction between the aspirin group and the non-aspirin group (χ2=0.820, P=0.365). The incidence of non-fatal myocardial infarction was lower than that of the aspirin non-aspirin group (χ2=10.099, P=0.01) , the incidence of massive hemorrhage was significantly higher than that of aspirin-free group χ2=5.425, P=0.020) . In a subgroup analysis of aspirin use, patients younger than 60 years of age had a lower incidence of ischemic stroke (cerebral infarction) and a risk ratio of 0.428 (95%CI: 0.255-0.719, P=0.001) compared with patients older than 60 years of age, the incidence of cerebral infarction was higher in female patients with a risk ratio of 1.574 (95%CI: 1.018-2.434, P=0.041). CONCLUSION: In this study of patients with type 2 diabetes, low-dose aspirin reduced the incidence of nonfatal myocardial infarction but had no significant effect on the incidence of nonfatal ischemic stroke, and significantly increase the incidence of major bleeding events, we should reconsider the use of low-dose aspirin as a potential benefit of nonfatal cerebral infarction in patients with type 2 diabetes.

Standard operation procedure and cost of primary public healthcare services / 中华健康管理学杂志

Objective To explore cost of standard operation procedure of primary public healthcare services.Methods Standard operation procedure of primary public healthcare services was put forward according to national basic public healthcare service standards (2011 edition) in 2012.Random sampling method was used to choose participants from two community sanitary service centers,two township heahhcare centers and one maternity and child heahhcare hospital.Service standard operation procedure was used to measure human cost and supportive cost of public healthcare services.Results Management of 10 thousand patients who had different diseases needed various numbers of medical staff (MS),such as health profile needed 3.4 MS,hypertension management needed 10.8 MS,diabetes management needed 10.6 MS,elderly people care needed 9.2 MS,child care needed 4.6 MS,maternal care needed 24.3 MS,psychosis management needed 13.3 MS,and planned immunity for children needed 4.6 MS.Besides,the people whole covered service projects need 2.4 MS per 100 thousand people.The research showed that managing 1 sample of different kind people needed different human cost,such as health profile needed 22.67 yuan,hypertension management needed 72.69 yuan,planned immunity for children needed 30.68 yuan,diabetes management needed 71.34 yuan,old people management needed 61.50 yuan,child care needed 30.88 yuan,maternal care needed 157.15 yuan,psychosis management needed 74.25 yuan.Besides,the people whole covered service projects needed 124.9 thousand yuan per 100 thousand people.Conclusion For primary public healthcare service project,it should be critical to modify manning regulation and labor costs.

Standardized management of hypertension in communities / 中华健康管理学杂志

Objective To confirm whether community management of hypertension could improve blood pressure control in Chongqing.Methods Cluster sampling method was used to select 5283 adults from 20 community healthcare centers in Chongqing.Matched t test was used to analyze the changes of blood pressure before and after the intervention.x2 test analysis was performed to compare the rate of normal blood pressure.Results The average age of 5283 participants was (60.5 ± 11.0) years old.Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were significantly decreased after intervention (total population:t values were 16.98 and 13.80,respectively; male:t values were 12.58 and 10.66,respectively; female:t values were 11.60 and 9.10,respectively; all P ＜ 0.05).The most significant decrease in SBP was found in 50-59 y age group (t =15.29,P ＜0.05),followed by 40-49 y age group (t =9.22,P ＜0.05).The control rate of hypertension was increased by 5.3％ after 1 year's intervention (x2 =134.5,P＜0.05),except for 60-69 y age group and ≥70 y age group (x2 values were 2.5 and 1.7,respectively ; both P ＞ 0.05).Conclusion Our results show that standardized management of hypertension in communities can decrease the level of blood pressure and increase the control rate of hypertension.
