Objective: To investigate the epidemiological characteristics of newly reported HIV/AIDS cases at ages of 50 years and older in Zhengzhou City from 2017 to 2021, so as to provide the evidence for formulating the AIDS control measures among the elderly. Methods: Epidemiological data of newly reported HIV/AIDS cases at ages of 50 years and older in Zhengzhou City from 2017 to 2021 were collected through the Zhengzhou Municipal Intelligent Public Health Management System. The epidemiological characteristics including population distribution, transmission route and route of detection were analyzed using a descriptive epidemiological method. Results: A total of 533 newly reported HIV/AIDS cases at ages of 50 years and older were diagnosed in Zhengzhou City from 2017 to 2021, accounting for 25.94% of all HIV/AIDS cases. There were 400 male cases and 133 female cases, with a male-to-female ratio of 3.01∶1, 288 cases at ages of 50 to 59 years (54.03%), 467 cases with an educational level of junior high school and below (87.62%), 391 cases with household registered residence in Zhengzhou City (73.36%), and 333 farmers (62.48%). Sexual contact was the main route of transmission (524 cases, 98.31%), and HIV/AIDS cases were predominantly detected by medical institutions (305 cases, 57.22%), followed by counseling and testing (167 cases, 31.33%). The proportion of HIV/AIDS cases diagnosed by medical institutions appeared a tendency towards a decline in Zhengzhou City from 2017 to 2021 (χ2trend=10.953, P=0.001), while the proportion of HIV/AIDS cases diagnosed by counseling and testing showed a tendency towards a rise (χ2trend=5.438, P=0.020). Conclusions The newly reported HIV/AIDS cases at ages of 50 years and older were predominantly local male farmers in Zhengzhou City from 2017 to 2021, with sexual contact as the main transmission route and medical institutions as the predominant route of detection. The proportion of newly reported HIV/AIDS cases appeared a tendency towards a rise.

OBJECTIVE:To compare the efficacy and safety of ferrous succinate or Shengxuening in the adjuvant treatment of renal anemia in patients with diabetic nephropathy peritoneal dialysis (CAPD). METHODS:64 diatetic nephropathy CAPD pa-tients with renal anemia were randomly divided into observation group (32 cases) and control group (32 cases). All patients re-ceived subcutaneous injection of insulin for blood glucose control (adjusted the insulin dosage based on fasting blood glucose lev-els),hypertension patients actively controlled blood pressure,corrected acid-base and electrolyte balance disorders,orally received fo-lic acid and vitamin B12,ambulant CAPD,then rhEPO was subcutaneously injected with initial dose of 100-150 U/(kg·week) for 2-3 times and other conventional treatment. Based on it,observation group received 1 g of Shengxuening tablet,3 times a day;control group received 0.2 g Ferrous succinate tablet,3 times a day. The treatment course for both groups was 16 weeks. The rhEPO dose was monthly adjusted to make Hb 100-120 g/L. Clinical efficacy,serum iron,serum ferritin,total iron binding capacity,transfer-rin saturation before and after treatment,Hb,Hct,hs-CRP,rhEPO dose before treatment and after 4,8,12 and 16 weeks of treat-ment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:There was no significant difference in the total effective rate between 2 groups (P>0.05). After treatment,serumiron,total iron binding capacity,transferrin saturation,Hb and Hct in 2 groups were significantly higher than before,and it gradually increased by treatment time,serum ferritin,hs-CRP was sig-nificantly lower than before,and it gradually decreased by treatment time,the differences were statistically significant(P<0.05);but there was no significant difference between 2 groups(P>0.05). The rhRPO dose in observation group 8,16 and 16 weeks af-ter treatment and in control group 8 weeks after treatment were significantly lower than 4 weeks after treatment,and 12 and 16 weeks after treatment in observation group were lower than control group,the differences were statistically significant (P<0.05). The incidence of adverse reactions in observation group was significantly lower than control group,the difference was statistically significant(P<0.05). CONCLUSIONS:Based on conventional treatment,both ferrous succinate and Shengxuening show good ef-ficacy in the adjuvant treatment of renal anemia with diabetic nephropathy CAPD,both can improve anemia and iron metabolism, while Shengxuening is superior to ferrous succinate in terms of improving microinflammatory state and reducing rhEPO dose,with better safety.
