Objective: To understand characteristics of men who have sex with men (MSM) who applied for HIV antibody self-testing reagents through "AIDS self-testing" column of a WeChat official account named "Dark Blue Public Health Center" in Tianjin City, so as to provide insights into exploring online modes of HIV antibody self-testing for MSM. Methods: Data of MSM who were 18 years old or above, currently lived in Tianjin City, had sex with men in the past six months and applied for HIV antibody self-testing reagents through "AIDS self-testing" column from May 2018 to December 2022 were collected. Demographic characteristics, results return and positive findings were descriptively analyzed. Results: Data of 2 064 MSM were collected, including 1 052 MSM aged 20 to 29 years (50.97%), 1 522 unmarried MSM (73.74%), 545 workers (26.41%), 1 385 MSM with college education or above (67.10%), and 315 MSM without testing for HIV antibody in the past (15.26%). A total of 6 470 self-testing reagents were applied, and 5 942 testing results were returned, with a return rate of 91.84%. There were 33.28% (687/2 064) of the applicants applying for 66.32% (4 291/6 470) reagents multiple times. There were 73 MSM with positive results, accounting for 1.23%. Conclusions The MSM applying for HIV antibody self-testing reagents through "AIDS self-testing" are mainly young and highly educated, including some who have never tested for HIV. However, attention should be paid to duplicate applications and the return rate should be increased.

ObjectiveTo investigate and compare the prevalence,awareness and risk factors of chronic kidney disease (CKD) between urban and rural population in Guangxi province in order to provide information for prevention and treatment of CKD.MethodsBy a stratified multistage random sampling method,18 to 74 years old residents in Guangxi province were surveyed. They wereevaluatedbyquestionnaire,urinaryalbumin/creatinineratio, hematuria (microscopic examination of centrifuged urine sediment),kidney B-mode ultrasound,and abnormal results were reviewed 3 months later.Estimated glomerular filtration rate(eGFR) was calculated with the simplified MDRD equation modified by a Chinese coefficient.The risk factors associated with CKD were also investigated.Results There were no significant differences between urban and rural residents in the prevalence of albuminuria (5.22％ vs 5.47％) and hematuria (1.07％ vs 1.11％)(all P＞0.05).The prevalence of renal lithiasis in rural residents was significantly higher than that in the town(10.54％ vs 6.95％)(P＜0.05).The decreased renal function between urban and rural residents(3.87％ vs 4.04％,P＞0.05) had no significant difference.The prevalence of CKD was 9.58％ in urban and 9.42％ in rural(P＞0.05).The prevalence of albuminuria according to the age distribution was different between urban and rural,which increased along with the age in urban but showed two peaks(30-40 years old and 60-74 years old) in rural.Based on logistic regression analysis,the risk factors for albuminuria were diabetes,hyperuricemia,the history of cardiovascular disease,chronic tonsillitis and HBsAg positive.The risk factors for kidney function decline were age,hyperuricemia,hypertension,diabetes,renal lithiasis and history of cardiovascular disease.The awareness rate of CKD in urban was significantly higher than that in rural (14.45％ vs 6.27％,P＜0.05).Conclusions The prevalenceof CKD has no significant difference between urban and rural in Guangxi province.The awareness rate of CKD in urban is significantly higher than that in rural.It is needed to enhance the prevention and treatment of CKD in rural.

Diuretics are the first-line drugs for the treatment of hypertension. Long-term use of diuretics often causes elevated blood sugar, electrolyte disturbances (most commonly hypokalemia), abnormal lipid metabolism (such as increased triglycerides, elevated cholesterol), increased serum uric acid levels and so on. In order to clarify the specific mechanism of the adverse reactions related to diuretics which are widely used in the treatment of hypertension, many documents have reported the pharmacogenomics research of diuretics-related adverse reactions. This review discusses the related genes and their variants of adverse reactions caused by commonly used diuretics in the treatment of hypertension in hope of providing a basis for the study of individualized use of diuretics.

OBJECTIVETo evaluate the effect of Fuzheng Quxie granule (FQG) on immune cells and cytokines of populations susceptible to respiratory viral infection.

METHODSOne thousand four hundred and two subjects selected from 25 hospitals in Shanghai between May and June in 2003, were divided into the FQG group treated with FQG and the control group treated with placebo. Serum levels of interleukin 2 (IL-2), interleukin 4 (IL-4), gamma-interferon (gamma-IFN), blood lymphocyte subsets (CD3+ , CD4+, CD8+), B-cell count and natural killer cell (NK) percent ratio were measured in 130 of the FQG group and 120 of the control group before treatment, by the end of the 2nd week and two weeks after treatment.

RESULTSBy the end of the 2nd week of treatment, as compared with before treatment, the levels of IL-2, gamma-IFN, and NK percent in the FQG group increased significantly (P < 0.05), while IL-4 and CD3+, CD4+, CD8+ and B-cell count were unchanged. Besides, levels of Th1/Th2 ratio markedly increased at the end of the 2nd week and two weeks after treatment, in comparing with that before treatment and in the control group (P<0.05).

CONCLUSIONFQG could improve immune function of population susceptible to respiratory viral infection certain extent.

The present research work primarily investigated whether spinosin has the potential of improving the pathogenesis of Alzheimer’s disease (AD) driven by β-amyloid (Aβ) overproduction through impacting the procession of amyloid precursor protein (APP). Wild type mouse Neuro-2a cells (N2a/WT) and N2a stably expressing human APP695 (N2a/APP695) cells were treated with spinosin for 24 h. The levels of APP protein and secreted enzymes closely related to APP procession were examined by western blot analysis. Oxidative stress related proteins, such as nuclear factor-erythroid 2-related factor 2 (Nrf2), and heme oxygenase-1 (HO-1) were detected by immunofluorescence assay and western blot analysis, respectively. The intracellular reactive oxygen species (ROS) level was analyzed by flow cytometry, the levels of Aβ1-42 were determined by ELISA kit, and Thioflavin T (ThT) assay was used to detect the effect of spinosin on Aβ1-42 aggregation. The results showed that ROS induced the expression of ADAM10 and reduced the expression of BACE1, while spinosin inhibited ROS production by activating Nrf2 and up-regulating the expression of HO-1. Additionally, spinosin reduced Aβ1-42 production by impacting the procession of APP. In addition, spinosin inhibited the aggregation of Aβ1-42. In conclusion, spinosin reduced Aβ1-42 production by activating the Nrf2/HO-1 pathway in N2a/WT and N2a/ APP695 cells. Therefore, spinosin is expected to be a promising treatment of AD.

OBJECTIVETo investigate the effect of fuzheng quxie granule (FQG) on immune cells and cytokines in populations with respiratory viral infection.

METHODSFifty-nine patients were randomly divided into 3 groups, that is, 19 patients treated with conventional western medicine (WM) plus FQG in the treated group, 19 patients treated with conventional western medicine alone in the WM group, and 21 patients treated with FQG alone in the TCM group. The levels of T lymphocyte subsets, interleukine-2,4,6,10 (IL-2, IL-4, IL-6, IL-10), tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (INF-gamma) and Th1/Th2 were determined before treatment, and at the end of 1st and 2nd week of treatment respectively.

RESULTSBefore treatment, levels of TNF-alpha, IL-2, IL-6, IL-10 and INF-gamma in all patients were significantly higher than normal range (P < 0.05). After being treated for 1 week, the levels of serum TNF-alpha, IL-6, and IL-10 were significantly decreased in all groups (P < 0.05), serum IL-2 and INF-gamma decreased to the normal level in the WM group, but in the treated and the FQG group by the end of the 2nd week, the two indexes still remained at the rather higher level (P < 0.05). The ratio of Th1 and Th2 in the treated group and the FQG group increased significantly by the end of 2nd week, reached the level higher than that in the WM group and that before treatment (P < 0.05). No significant difference in, T lymphocytes subsets (CD3+ , CD4+ , CD8+) and percentage of B and NK cells before and after treatment was found in all the 3 groups.

CONCLUSIONFQG can positively regulate the immune function of patients with respiratory tract viral infection in certain degree.

Neurovascular coupling (NVC) is the basis of neuronal activity and metabolism, and its dysfunction may be closely associated with the occurrence and development of the nervous system diseases. Functional transcranial doppler ultrasonography (fTCD) can evaluate the NVC function. FTCD researches have shown that ischemic stroke, vascular cognitive impairment and other patients have NVC dysfunction. This article reviews the methods of fTCD examination of NVC and its clinical application.

Objective:To analyze risk factors for unfavorable outcomes after recanalization of large vessel occlusion (LVO) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS-LVO who underwent recanalization treatment (including intravenous thrombolysis and endovascular intervention) at the Stroke Unit of Beijing Hospital from August 2018 to January 2022 were consecutively enrolled. According to the modified Rankin Scale (mRS) at 90-day follow-up after recanalization treatment, participants were classified as unfavorable outcomes (mRS>2) and favorable outcomes (mRS≤2). Baseline clinical data of enrolled patients was collected, and step-wise multivariate logistic regression analysis was used to identify independent risk factors for unfavorable outcomes after recanalization in AIS-LVO patients.Results:A total of 212 AIS-LVO patients were enrolled, including 86 females (41.35%), with an average age of 72.9 years. There were 75 patients in the favorable outcome group and 137 patients in the unfavorable outcome group. Compared with the favorable outcome group, the unfavorable outcome group had a higher average age, a higher proportion of females and patients with atrial fibrillation, higher baseline NIHSS, higher systolic blood pressure, and higher blood creatinine and D-dimer levels (all P<0.05). After adjusting for age and atrial fibrillation as confounding factors, multivariate logistic regression analysis showed that female ( OR=2.859, 95% CI: 1.202-6.799, P=0.018), higher baseline NIHSS ( OR=14.417, 95% CI: 6.269-33.158, P<0.001), higher pre-treatment systolic blood pressure ( OR=1.034, 95% CI: 1.015-1.054, P=0.001), higher emergency blood creatinine level ( OR=1.378, 95% CI: 1.105-1.719, P=0.005), and higher D-dimer level ( OR=3.594, 95% CI: 1.290-10.014, P=0.014) were independent risk factors for unfavorable outcomes after recanalization treatment in patients with AIS-LVO. Conclusion:Female, higher NIHSS, higher systolic blood pressure, higher blood creatinine level and D-dimer level are independent risk factors for unfavorable functional outcomes at 90 days after recanalization treatment of large vessel occlusion in patients with acute ischemic stroke.
