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.

The formation of physique was influenced by many factors and was closely related to the disease, especially by the social and cultural factors. According to the characteristics of physique, physique conditioning was conducive to rehabilitation of the disease. It was also the internal evidence for individualized treatment of rehabilitation. Traditional Chinese medicine (TCM) rehabilitation advocated functional rehabilitation as the main treatment purpose. Attentions were paid to promoteqi circulation. The psychological characteristics of the rehabilitation subject were especially emphasized on, in order to improve the therapeutic effect of rehabilitation. There were many classifications of physical evaluations, which were widely used in a variety of clinical diseases rehabilitation. The pathological physique correction and adjustment cannot be ignored in rehabilitation. Therefore, the application of physical evaluation in the guidance of rehabilitation therapy can enrich the content of TCM rehabilitation evaluation. It further improved TCM physical evaluation system to meet the needs for clinical practice and TCM modernization.

Objective: To analyze the pathogenic spectrum of infectious diarrhea among children in Zhengzhou City in 2020, so as to provide insights into the management of childhood infectious diarrhea. Methods: A total of 230 stool samples were collected from children with diarrhea in the Diarrhea Clinic of Zhengzhou Municipal Children's Hospital in 2020. Diarrheagenic Escherichia coli, Salmonella, Shigella, Vibrio parahaemolyticus, Campylobacter and Aeromonas were isolated. Salmonella was typed using pulsed-field gel electrophoresis ( PFGE ) and antimicrobial resistance was tested in Salmonella. The main types and drug resistance of pathogens were descriptively analyzed. Results: The 230 children with diarrhea included 152 males and 78 females, with a male to female ratio of 1.95∶1. There were 173 cases at ages of 3 years and below ( 75.22% ), and 82 cases seen between June and August ( 35.65% ). A total of 71 pathogenic bacteria strains were isolated, with a detection rate of 30.87%. Salmonella was the most frequently isolated pathogen ( 35 strains, 15.22% prevalence ), following by diarrheagenic E. coli ( 20 strains, 8.70% ). Eleven serotypes of Salmonella were identified, which mainly included S. enteritidis and S. typhimurium. PFGE typing revealed 25 band patterns of Salmonella, with a similarity ranging from 11.85% to 100%. Salmonella were sensitive to imipenem, meropenem, polymyxin B and amikacin and highly resistant to streptomycin ( 85.71% ), ampicillin ( 80.00% ) and sulfaisoxazole ( 80.00% ). A 82.86% proportion of multi-drug resistance was detected in the 29 Salmonella strains. Conclusions A wide range of pathogenic bacteria were detected from the childhood infectious diarrhea in Zhengzhou City in 2020, which mainly included Salmonella and diarrheagenic E. coli. A high polymorphism level was seen in PFGE fingerprints of Salmonella, which presented high-level resistance to antimicrobial agents.

Objective: To investigate the serotypes and drug resistance of non-typhoidal Salmonella in Zhengzhou City, so as to provide insights into prevention and control of non-typhoidal Salmonella infections. Methods: Salmonella isolates were collected from diarrheal patients in Zhengzhou municipal sentinel hospitals from 2017 to 2021. Salmonella serotypes were identified using slide agglutination test and soft agar colony formation assay, and antimicrobial susceptibility test was performed using the broth micro-dilution method. Results: Five serogroups and 37 serotypes were identified among 446 non-typhoidal Salmonella isolates, with S. enteritidis (210 isolates, 47.09%) and S. typhimurium (133 isolates, 29.82%) as dominant serotypes. Non-typhoidal Salmonella showed high resistance to ampicillin (79.60%), ampicillin/sulbactam (58.74%), naphthyric acid (56.05%), tetracycline (54.26%) and doxycycline (54.04%), respectively. There were 290 multidrug-resistant Salmonella isolates (65.02%), and the multidrug resistance rates were 70.48% for S. enteritidis and 67.67% for S. typhimurium, respectively. Conclusions Multiple serotypes of non-typhoidal Salmonella were identified in Zhengzhou City from 2017 to 2021, with S. enteritidis and S. typhimurium as dominant serotypes. Widespread drug resistance and multidrug resistance was seen in non-typhoidal Salmonella.

Objective:In general, patients with seropositive rheumatoid arthritis (RA) are considered to show an aggressive disease course. However, the relationship between the two subgroups in disease severity is controversial. Our study is aimed to compare the clinical characteristics and prognosis of double-seropositive and seronegative RA in China through a real-world large scale study.Methods:RA patients who met the 1987 American College of Rheumatology (ACR) classification criteria or the 2010 ACR/European Anti-Rheumatism Alliance RA classification criteria, and who attended the 10 hospitals across the country from September 2015 to January 2020, were enrolled. According to the serological status, patients were divided into 4 subgroups [rheumatoid factor (RF)(-) anti-cyclic citrullinated peptide (CCP) antibody (-), RF(+), RF(+) anti-CCP antibody(+), anti-CCP antibody(+)] and compared the disease characteristics and treatment response. One-way analysis of variance was used for measurement data that conformed to normal distribution, Kruskal-Wallis H test was used for measurement data that did not conform to normal distribution; paired t test was used for comparison before and after treatment within the group if the data was normally distributed else paired rank sum test was used; χ2 test was used for count data. Results:① A total of 2 461 patients were included, including 1 813 RF(+) anti-CCP antibody(+) patients (73.67%), 129 RF(+) patients (5.24%), 245 RF(-) anti-CCP antibody(-) patients (9.96%), 74 anti-CCP antibody(+) patients (11.13%). ② Regardless of the CCP status, RF(+) patients had an early age of onset [RF(-) anti-CCP antibody(-) (51±14) years old, anti-CCP antibody(+) (50±15) years old, RF(+) anti-CCP antibody(+) (48±14) years old, RF(+)(48±13) years old, F=3.003, P=0.029], longer disease duration [RF(-) anti-CCP antibody(-) 50 (20, 126) months, anti-CCP antibody(+) 60(24, 150) months, RF(+) anti-CCP antibody(+) 89(35, 179) months, RF(+) 83(25, 160) months, H=22.001, P<0.01], more joint swelling counts (SJC) [RF(-) anti-CCP antibody(-) 2(0, 6), Anti-CCP antibody(+) 2(0, 5), RF(+) anti-CCP antibody(+) 2(0, 7), RF(+) 2(0, 6), H=8.939, P=0.03] and tender joint counts (TJC) [RF(-) anti-CCP antibody(-) 3(0, 8), anti-CCP antibody(+) 2(0, 6), RF(+) anti-CCP antibody(+) 3(1, 9), RF(+) 2(0, 8), H=11.341, P=0.01] and the morning stiff time was longer [RF(-) anti-CCP antibody(-) 30(0, 60) min, anti-CCP antibody(+) 20(0, 60) min, RF(+) anti-CCP antibody(+) 30(10, 60) min, RF(+) 30(10, 60) min, H=13.32, P<0.01]; ESR [RF(-) anti-CCP antibody(-) 17(9, 38) mm/1 h, anti-CCP antibody(+) 20(10, 35) mm/1 h, RF(+) anti-CCP antibody(+) 26(14, 45) mm/1 h, RF(+) 28(14, 50) mm/1 h, H=37.084, P<0.01] and CRP [RF(-) anti-CCP antibody(-) 2.3 (0.8, 15.9) mm/L, Anti-CCP antibody(+) 2.7(0.7, 12.1) mm/L, RF(+) anti-CCP antibody(+) 5.2(1.3, 17.2) mm/L, RF (+) 5.2(0.9, 16.2) mm/L, H=22.141, P<0.01] of the RF(+)patients were significantly higher than RF(-) patients, and RF(+) patients had higher disease severity(DAS28-ESR) [RF(-) anti-CCP antibody(-) (4.0±1.8), anti-CCP antibody(+) (3.8±1.6), RF(+) anti-CCP antibody(+) (4.3±1.8), RF(+) (4.1±1.7), F=7.269, P<0.01]. ③ The RF(+) anti-CCP antibody(+) patients were divided into 4 subgroups, and it was found that RF-H anti-CCP antibody-L patients had higher disease severity [RF-H anti-CCP antibody-H 4.3(2.9, 5.6), RF-L anti-CCP antibody-L 4.5(3.0, 5.7), RF-H anti-CCP antibody-L 4.9(3.1, 6.2), RF-L anti-CCP antibody-H 2.8(1.8, 3.9), H=20.374, P<0.01]. ④ After 3-month follow up, the clinical characteristics of the four groups were improved, but there was no significant difference in the improvement of the four groups, indicating that the RF and anti-CCP antibody status did not affect the remission within 3 months. Conclusion:Among RA patients, the disease activity of RA patients is closely related to RF and the RF(+) patients have more severe disease than RF(-) patients. Patients with higher RF titer also have more severe disease than that of patients with low RF titer. After 3 months of medication treatment, the antibody status does not affect the disease remission rate.
