Objective To analyze the epidemiological and pathogenic characteristics of acute respiratory in-fection in Yangpu District of Shanghai,and to provide scientific basis for the prevention and treatment of re-spiratory tract infection.Methods A total of 1 062 patients diagnosed with acute respiratory infection in the hospital from June 2023 to June 2024 were selected as the research objects.The nucleic acid of 13 pathogens in nasopharyngeal swabs of patients was detected and the positive rate was calculated.The positive rate of differ-ent age groups and seasons was analyzed.Results Among 1 062 patients,716 cases were detected positive,the total positive rate was 67.42%,of which 577 cases were single infection,the positive rate was 54.33%.The top five positive pathogens were Mycoplasma pneumoniae(MP,16.48%),human coronavirus(HCOV,9.42%),human rhinovirus(HRV,7.63%),human metapneumovirus(HMPV,5.46%)and parainfluenza vi-rus(HPIV,3.39%).A total of 139 cases were infected with multiple pathogens,with a positive rate of 13.09%.MP,HRV,and HCOV were the dominant pathogens,which were prone to multiple infections.A to-tal of 139 cases were infected with multiple pathogens,with a positive rate of 13.09%.MP,HRV,and HCOV were the dominant pathogens,which were prone to multiple infections.The total positive rate of respiratory pathogens in children was 86.38%,the positive rates of single infection and multiple infection were 65.12%and 21.26%,respectively,which were significantly higher than those in other age groups(P<0.05).Among the 577 children with single infection,MP and HRV were the main pathogens in children,MP and HCOV were the main pathogens in young and middle-aged patients,and HCOV and HRV were the main pathogens in the elderly patients.The total positive rate of pathogens was the highest in winter(69.88%),and the lowest in summer(49.54%).HRV had the highest positive rate in spring,HCOV had the highest positive rate in summer,MP had the highest positive rate in autumn,and influenza virus(including influenza A virus,influen-za A/H3N2 virus,influenza B virus)had the highest positive rate in winter(P<0.05).Conclusion MP,HCOV,HRV,HMPV and HPIV are the top five pathogens of acute respiratory tract infection in Yangpu dis-trict of Shanghai.The etiological characteristics were related to age and seasonality of patients.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective To investigate the relationship between the expression of matrix metalloproteinase(MMP)-2,MMP-9,MMP-13 and disease activity in pemphigus patients.Methods A total of 60 pemphigus patients treated in the dermatology department of the hospital from January 2021 to January 2023 were select-ed as the study group,and another 60 healthy volunteers who underwent physical examination in the same pe-riod were recruited as the control group.The levels of MMP-2,MMP-9 and MMP-13 in serum and the expres-sion of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells were compared between the two groups,and the relationship between the expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells of patients with pemphigus was analyzed.Pemphigus patients were divided into acute phase group(n=22),chronic phase group(n=23)and stable phase group(n=15)according to their disease activi-ty.The expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells of the three groups were compared,as well as the correlation between the three indexes and disease activity.Receiver operating characteristic(ROC)curve was plotted for analysis.Results The levels of MMP-2,MMP-9 and MMP-13 in serum and the expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells in the study group were higher than those in the control group,with statistical significance(P＜0.05).The expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells in severe patients were higher than those in moderate and mild patients,and the difference was statistically significant(P＜0.05).The expression of MMP-2,MMP-9 and MMP-13 and disease activity scores of mononuclear cells in acute attack group were higher than those in chronic attack group,and the differences were statistically significant(P＜0.05).The ex-pression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells were positively correlated with disease activity(rMMP-2=0.545,rMMP-9=0.592,rMMP-13=0.580,P＜0.05).ROC curve analysis showed that compared with the single diagnostic efficacy of MMP-2,MMP-9 and MMP-13 expression in peripheral blood mononuclear cells,the three combined diagnostic efficacy was better.Conclusion The expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells of pemphigus patients is related to the disease activity,and these three indicators can be used as reference indicators for the diagnosis of pemphigus disease activity.

Objective:To investigate the efficacy and safety of endoscopic ligation and injection sclerotherapy for internal hemorrhoids.Methods:From April 2020 to October 2023, 106 patients with grade Ⅰ to Ⅲ internal hemorrhoids who underwent endoscopic ligation or injection sclerotherapy in the First Affiliated Hospital with Nanjing Medical University (Jiangsu Province People's Hospital) were consecutively enrolled in the retrospective cohort study. Patients were divided into the ligation group ( n=70) and the injection sclerotherapy group ( n=36) according to the endoscopic treatment methods. The effective rate, hospital stay, postoperative pain, the incidence of complications, patient satisfaction and the recurrence rate of the two groups were assessed. Results:The effective rate was 95.7% (67/70) and 100.0% (36/36) respectively in the ligation group and the injection sclerotherapy group without significant difference ( P=0.549). The hospital stay was 6.0 (4.0, 7.3) days and 3.0 (2.0, 4.0) days respectively in the ligation group and the injection sclerotherapy group with significant difference ( Z=4.305, P<0.001). The incidence of 24-hour postoperative pain was 58.6% (41/70) and 11.1% (4/36) in the two groups respectively and the difference was statistically significant ( χ2=20.020, P<0.001). There were no serious postoperative adverse events such as anal stenosis or thrombotic external hemorrhoids in the two groups. Only the incidence of anal distension was significantly different between the ligation group and the injection sclerotherapy group [38.6% (27/70) VS 5.6% (2/36), χ2=11.431, P<0.001]. The patient satisfaction rate of the two groups showed no significant difference [87.1% (61/70) VS 86.1% (31/36), P=1.000]. There was 1 patient and 15 patients lost to follow-up respectively in the ligation group and the injection sclerotherapy group, and the recurrence rate of the two groups showed no significant difference [14.5% (10/69) VS 33.3% (7/21), P=0.064]. Subgroup analysis of grade Ⅰ-Ⅱ internal hemorrhoids: there were 43 patients and 29 patients in the ligation group and the injection sclerotherapy group, respectively. No significant difference was found between the two groups in terms of the effective rate, incidence of postoperative hemorrhage, incidence of uroschesis, or patient satisfaction rate ( P>0.05). The incidences of postoperative pain [65.1% (28/43) VS 10.3% (3/29), χ 2=19.016, P<0.001] and anal distension [41.9% (18/43) VS 3.4% (1/29), χ 2=11.252, P<0.001] of the ligation group were significantly higher than those of the injection sclerotherapy group. Forty-three patients in the ligation group and 17 patients in the injection sclerotherapy group completed follow-up, and the recurrence rate was 11.6% (5/43) and 23.5% (4/17), respectively, without significant difference ( P=0.256). Subgroup analysis of grade Ⅲ internal hemorrhoids: there were 27 patients in the ligation group and 7 patients in the injection sclerotherapy group, and 26 and 4 patients completed follow-up, with a recurrence rate of 19.2% (5/26) and 75.0% (3/4), respectively. Conclusion:Endoscopic ligation and injection sclerotherapy are both safe and effective for grade Ⅰ-Ⅲ internal hemorrhoids. Injection sclerotherapy demonstrates shorter hospital stays and lower incidences of postoperative pain and anal distension. For grade Ⅰ-Ⅱ internal hemorrhoids, injection sclerotherapy is recommended due to its efficacy and fewer complications. Conversely, for grade Ⅲ internal hemorrhoids, ligation is suggested to reduce recurrence rates.

Objective:To mine and analyze the signals of the adverse event (AE) of erenumab and provide reference for the safe application of the drug.Methods:The reports of AE from 2004 to the first quarter of 2023 were extracted from the US FDA Adverse Event Reporting System database, and the full data and data after 2018 were analyzed respectively. AEs were classified according to preferred term (PT) and the system organ class (SOC) of Medical Dictionary for Regulatory Activities (MedDRA) 23.0 version for statistical analysis. The reported odds ratio (ROR) method and Bayesian confidence progressive neural network (BCPNN) method were used to mine the AE risk signals.Results:A total of 38 348 AE reports with erenumab as the primary suspect drug were collected, involving 2 629 PTs. The number of risk signals screened by the ROR and BCPNN methods from the full data and data after 2018 was 99 and 115, respectively, involving 19 SOCs. Among them, the most frequently reported AEs were injection site reactions and constipation, which were consistent with the label. Among the top 30 PTs, 13 were not recorded in the label, including pineal cyst, postural tachycardia, positive histone antibody, spastic eye movements, fear of injection, post-concussion syndrome, Raynaud effect, psychogenic seizures, coronary artery dissection, premature menopause, trichorrhexis, collagen disease, and blepharospasm.Conclusion:In clinical application of erenumab, in addition to the adverse reactions recorded in the label, attention should also be paid to the adverse events mined in this study.

Objective:To explore the association between grip strength and cognitive function in elderly people aged 65 years and over.Methods:Information on grip strength, cognitive function, and lifestyle in the elderly population aged 65 years and over in Wuhan was collected by unified professionally trained investigators.A total of 533 study subjects aged(70.7±5.1)years were grouped by quartile into four grip strength groups of Q1(<18.6 kg), Q2(18.6~24.1 kg), Q3(24.2~31.1 kg), Q4(>31.1 kg).Multiple linear regression and Logistic regression analyses were used to analyze the relationship of grip strength with cognitive function scores and cognitive impairment.Results:The mean grip strength of the 533 subjects was(24.94±9.15)kg.After adjusting for sociodemographic characteristics, lifestyle factors, history of diseases, as compared with grip strength Q1 group, the linear regression coefficients(Beta value)of cognitive scores and 95% confidence intervals(95% CI)showed statistically significantly positive correlation[0.45(-0.36, 1.26)、0.40(-0.52, 1.32)and 1.19(0.07, 2.31), all P<0.05]only between cognitive scores and grip strength Q2、Q3 and Q4 value; and the odds ratio and 95% CI of incidence of cognitive impairment were 0.97(0.43, 2.21)for grip strength Q2, 0.79(0.30, 2.06)for grip strength Q3, and 0.22(0.05, 0.92)for grip strength Q4.Considering grip strength as the continuous variable, the risk of cognitive impairment was decreased by 6% and the cognitive score was increased by 0.07 with per 1kg increase of grip strength. Conclusions:The results of this study suggest that there is a positive correlation between grip strength and cognitive function in the elderly population, and a lower grip strength is related to increased risk of cognitive impairment.More attention should be paid to the grip strength of the elderly in the community.

Objective:To explore the association between resting heart rate(RHR) and all-cause mortality among the Chinese oldest-old aged more than 80.Methods:Using a total of seven surveys or follow-ups data (1998, 2000, 2002, 2005, 2008, 2011 and 2014) from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). A total of 17 886 elderly over 80 years old were selected as subjects, their resting heart rate were measured though baseline survey and the survival outcome and death time of the subjects were followed up. The subjects were divided into 6 groups according to their resting heart rate. Cox regression model was used to estimate the effect of resting heart rate on mortality risk. The interaction of age, gender and resting heart rate was also analyzed by likelihood ratio test.Results:The age of subjects M( P25, P75) was 92 (86, 100) years old, including 10 531 females (58.9%) and there were 13 598 participants died, the mortality rate was 195.5 per 1 000 person-years. Multivariate Cox regression analysis showed that compared to the control group (60-69 pbm/min), the hazard ratio of the elderly are 1.06 (95% CI: 1.02, 1.11), 1.09 (95% CI: 1.04, 1.15), 1.23 (95% CI: 1.14, 1.34), 1.25 (95% CI: 1.08, 1.44) in the group of RHR between 70-79, 80-89, 90-99 and ≥100 pbm/min and Pvalues are all less than 0.05. Likelihood ratio test showed that RHR and age had an interaction effect. ( P for interaction=0.011). Conclusion:The risk of all-cause death increased with the increase of resting heart rate and this relationship was stronger between the 80-89 years old people.
