The number of people living with HIV/AIDS (PLHIV), new HIV infections, and deaths due to HIV in China were estimated. These data provided evidences for the analysis on current HIV/AIDS epidemic in China, development of AIDS prevention and control strategies and public health education. However, whether the estimation results could be fully used in practice depends on appropriate interpretation. Since the differences in estimation methods and data to produce the estimates for each year, it is not suitable to directly use the estimation results of different years to conclude the HIV/AIDS epidemic trends. The 2018 estimation results indicated that the number of PLHIV is already beyond one million by the end of 2018 and would keep growing, causing much pressure of for HIV/AIDS prevention and control. With the increased burden of case management, innovative strategies are needed to reduce secondary transmission of HIV and control the aggravating spread to general population. Less than 70%, which is significantly lower than the goal of China’s 13th Five-year Action plan for AIDS prevention and control. All local governments have the necessity of analyzing percentage of PLHIV who know their status, to conduct targeted strategies and measures for the improvement of HIV case finding. New HIV infection is the core indicator for HIV epidemic evaluation. The number of estimated new HIV infections is around 80 000 in 2018. It is necessary to further improve the strategy and increase the intensity to effectively reduce the new infection of HIV.

Objective:To evaluate the association between the efficacy and safety of metformin and the influence of variants in SLC47A1 rs2289669 G>A polymorphism in the treatment of systemic lupus erythematosus (SLE).Methods:A multicenter, randomized, double-blind, placebo-controlled trial was conducted. Patients were consented at enrollment for blood donation for genotyping, and their peripheral blood were used to detect the distribution frequency of SLC47A1 mutations. The major or mild/moderate flares defined by modified safety lupus erythematosus national assessment (SELENA)-systemic lupus erythematosus disease activity index (SLEDAI) Flare Index (SFI) and adverse events were recorded at 12 months of follow-up. The correlation between efficacy/safety and genotype was analyzed. Student's t test and χ2 test was used to assess the continuous variables and categorical variables. Results:Between May 24, 2016, and Dec 13, 2017, a total of 31 patients in the metformin group and 35 in the placebo group were detected. There were no statistical significant differences in the clinical manifestations, SELENA-SLEDAI scores, and therapy of the participants at baseline. There was no significant difference in the frequency of AA genotype, GA genotype, and GG genotype of SLC47A1 rs2289669 distribution between the metformin group and the placebo group. In the metformin group, patients who flared had a lower frequency of A alleles than those non-flared [25%(4/16) vs 61%(28/46), χ2=6.116, P=0.019 8]; the flare rate was significantly lower in patients with AA genotype than in GG genotype [0%(0/8) vs 57%(4/7), χ2=6.234, P=0.012 5]. The infection rate was lower in the metformin group than that in the placebo group [38%(12/31) vs 69%(24/35), χ2=5.913, P=0.015 0], but there was no significant difference among different genotypes in the metformin group. Compared to GG geno-type, AA genotype showed a trend of decrease in infection rate[38%(3/8) vs 72%(5/7), χ2=1.727, P=0.188 8]. Conclusion:Metformin has a favorable safety profile and may reduce the frequency of flares in SLE patients with low-grade lupus disease activity. The metformin therapeutic efficacy in SLE is relevant to the SLC47A1 gene polymorphism. Patients of the AA genotype may benefit most from metformin than those of the GG and GA genotypes.

Objective To explore the risk factors of pulmonary artery hypertension (PAH) and the its relationship with T cell subsets to provide a foundation for the prevention and treatment of PAH.Methods 154 maintained hemodialysis (MHD) patients in our dialysis center were recruited according to the criterion and divided into two groups subsequently:PAH group (pulmonary artery systolic pressure,PASP ＞ 35 mmHg) and non-PAH group (PASP≤35 mmHg).The related clinical,biochemical and ultrasonic cardiogram data were collected and peripheral blood was acquired to detect the expressions of the surface antigen CD3,CD4,CD8 and CD69 with flow cytometry.Logistic regression analysis was used to find out the relationship between PAH and T cell subsets.Results There was no significant difference between 56 cases of PAH and 98 cases of non-PAH as regards gender,age,mean systolic and diastolic pressure,dialysis durations,morbidities of hypertension and diabetes,smoking rate,and left ventricular diameter.Compared with the non-PAH group,the PAH group demonstrated a lower percent of CD8 T cells and CD8 CD69 T cells,but a much higher left atrial diameter (LAD),Interventricular septum thickness,left ventricular posterior wall thickness,and NT-proBNP.The percentage of T cells,CD4 T cells and CD4 CD69 T cells showed no difference between the two groups.Multivariate analysis confirmed that PAH was negatively independently associated with the percentage of CD8 T cells and CD8CD69 T cells.Conclusions The decreased percentage of CD8 T cells and CD8CD69 T cells in the peripheral blood is a risk factor of PAH in maintained hemodialysis patients,and CD8 T cells may play an important role in the genesis of PAH.

Objective:To describe the family resilience experience of colorectal cancer patients′ spouses in the process of care, and to provide reference for making effective clinical nursing interventions.Methods:Objective sampling method was used to select the spouses of colorectal cancer patients who were hospitalized in Shanghai East Hospital from March to April 2023. A phenomenological research was used. Semi-structured, in-depth interviews were conducted with 10 spouses of colorectal cancer patients undergoing colostomy. Data was transcribed and analyzed using Colaizzi′s method.Results:Three themes were extracted: family crisis and coping pressure including increased burden of care, accompanying emotional internal friction, heavy economic pressure; internal adjustment and adaptation within the family including positive family beliefs, timely adjustment of family roles, clear and effective communication and interaction; integration and utilization of external resources including active access to information, medical professional support, social external support.Conclusions:With the help of the perspective of family advantage, medical staff should pay attention to the evaluation of care needs and family resilience of colorectal cancer patients′ spouses, to fully mobilize advantage resources and give effective intervention measures to improve the family and social adaptation level of patients and their spouses.

Objective:To compare the proportion of abnormal renal function indexes in outpatients with chronic hepatitis B (CHB), and to further explore the correlation between the history of nucleos(t)ide analogues (NA) antiviral therapy and abnormal renal function indexes.Methods:A cross-sectional design was adopted for renal function screening. Baseline characteristics, history of antiviral treatment, and renal function indexes were collected, including glomerular filtration rate (eGFR), blood urea nitrogen, blood creatinine, blood uric acid, and urine β2- microglobulin α 1-microglobulin and urinary protein. According to the definition and standard of abnormal renal function indexes, the correlation between chronic kidney disease (CKD) - 1/2 and related risk factors, renal tubular indicators and risk factors, and the correlation between antiviral treatment duration and renal tubular risk were analyzed. The data were analyzed by single and multi-factor regression.Results:2703 outpatients from 47 hospitals across the country were enrolled. 70.7% were males with an average age of 47.5 years. 15.5% of cases had hypertension, 14.6% cases had chronic kidney disease, 11.3% cases had diabetes, and 15.4% had CKD 1/2. Retinol-binding protein, urinary β2-microglobulin or urinary α1-microglobulin showed renal tubular damage rates of 10.4%, 27.1% and 18.4%, respectively. Renal tubular damage risk was related to the antiviral treatment duration ( OR = 1.06, 95% CI = 1.028 ~ 1.093). Multivariate analysis results showed that the risk factors related to eGFR < 90 ml/min in male were 40-60 or > 60 years old, high viral load, poorly controlled hypertension, use of nephrotoxic drugs, liver fibrosis status, family history of hepatitis B; while the risk factors related to eGFR < 60 ml/min in female were decompensated cirrhosis, poorly controlled diabetes, and family history of hepatitis B. Conclusion:CHB outpatients have a high proportion of chronic kidney damage, including early renal tubular damage, which suggests that baseline renal function should be assessed before NA use and closely monitored during the treatment. Regular monitoring of the renal tubular damage index can detect the risk of kidney damage earlier than the estimated eGFR.

Objective To explore the needs of clinical nursing manager leadership skills, so as to provide a reference for the training and promotion. Methods Semi-structured interview was adopted in 15 nursing managers in 4 Jinan level three class A hospitals, and data were analyzed by Colaizzi′s phenomenological procedures. Results Four aspects were exacted for leadership skills: leadership power skills, management skills, professional skills, personal qualities. Conclusions The requirement of clinical nursing manager leadership skills is necessary and urgent, mainly concentrated on the management skills. The management skills should be strengthened, and pay attention to the power of leadership, professional skills and personal qualities at the same time, in order to adapt to the management requirements, and improve the quality of nursing management.
