Objective To study the characteristics of intestinal flora between diarrhea-predominant irritable bowel syndrome(IBS-D)and healthy population,and to provide a clinical basis for the basic research of IBS-D.Methods A total of 32 IBS-D patients admitted to Wenzhou People's Hospital,the Wenzhou Third Clinical Institute Affiliated to Wenzhou Medical University from January 2023 to June 2024 were selected as IBS-D group,and 33 healthy during the same period as control group.Cluster diversity was determined by 16S rDNA of clusters in feces and quantification of DNA.Results The diversity of IBS-D group decreased significantly than control group,and the relative abundance of proteobacteria increased in the IBS-D group,and the relative abundance of E.coli-Shigella and Klebsiella increased in the IBS-D group.Conclusion Intestinal microbiota diversity in IBS-D patients reduced and proteobacteria is the potential pathogen of IBS-D.

This study summarized the nursing experience of a patient with right-sided aortic arch and kommerell's diverticulum and thoracic aortic aneurysm complicated with acute coronary syndrome after thoracic endovascular aortic repair.The nursing points are as follows:optimizing emergency procedures to improve the quality of rescue;monitoring the condition of the patient dynamically to prevent postoperative complications;developing personalized rehabilitation training to promote postoperative recovery;implementing"Internet+"follow-up management to improve treatment compliance.After the comprehensive management of a multidisciplinary team and careful nursing care,the patient was discharged 12 days after operation.During 18-month follow-up,the patient was in good condition.

Objective:To summarize the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) infected with Delta variant, so as to provide further references for clinical diagnosis and treatment.Methods:A real-world study was conducted to analyze the characteristics of 166 COVID-19 patients infected with Delta variant at Guangzhou Eighth People’s Hospital, Guangzhou Medical University.Results:The study enrolled 5 asymptomatic cases, 123 non-severe cases (mild and moderate type), and 38 severe cases (severe and critical type). Among these patients, 69 (41.6%) were male and 97 (58.4%) were female, with a mean age of 47.0±23.5 years. Thirty-nine cases (23.5%) had received 1 or 2 doses of inactivated vaccine. The incidence of severe COVID-19 cases was 7.7% in 2-doses vaccinated patients, which was lower than that of 11.5% in 1-dose and 26.8% in unvaccinated patients. The proportion of severe cases in 2 dose-vaccinated patients was 7.7%, which was lower than that of 11.5% in 1-dose vaccinated patients and 26.8% in unvaccinated patients, but the difference was not significant ( P>0.05). The most common clinical symptom was fever (134 cases, 83.2%), and 39.1% of cases presented with high-grade fever (≥39 °C); other symptoms were cough, sputum, fatigue, and xerostomia. The proportion of fever in severe cases was significantly higher than that of non-severe cases (97.4% vs. 76.4%, P<0.01). Similarly, the proportion of severe cases with high peak temperature (≥39 ℃) () was also higher than that of non-severe cases (65.8% vs. 30.9%, P<0.01). The median minimal Cycle threshold (Ct) values of viral nucleic acid N gene and ORFlab gene were 20.3 and 21.5, respectively, and the minimum Ct values were 11.9 and 13.5, respectively. Within 48 h of admission, 9.0% of cases presented with decreased white blood cell counts, and 52.4% with decreased lymphocyte counts. The proportions of increased C-reactive protein, serum amyloid A, interleukin 6, and interleukin 10 were 32.5%, 57.4%, 65.3%, and 35.7%, respectively. The proportions of elevated C-reactive protein, serum amyloid A and interleukin-6 in severe cases were significantly higher than those in non-severe cases ( P<0.01). Logistic regression analysis showed that older age and higher peak temperature were associated with a higher likelihood of severe cases ( OR>3, 95% CI: 2-7, P<0.01). In terms of treatment, traditional Chinese medicine (TCM) was used in 97.6% of non-severe cases and 100% in severe cases. Other treatments included respiratory and nutritional support, immunotherapy (such as neutralizing antibodies and plasma of recovered patients). The median times from admission to progression to severe cases, of fever clearance, and of nucleic acid conversion were 5 days, 6 days and 19 days, respectively. No deaths were reported within 28 days. Conclusions:The symptoms of Delta variant infection in Guangzhou are characterized by a high proportion of fever, high peak temperature, long duration of fever, high viral load, a long time to nucleic acid conversion, and a high incidence of severe cases. The severe cases exhibit a higher percentage of elderly patients, a longer duration of fever and have a higher fever rate and a higher hyperthermia rate than non-severe cases. Age and hyperthermia are independent risk factors for progression to severe disease. The combination of TCM and Western medicine can control the progression of the disease effectively.

Objective: To investigate the situations of AIDS related knowledge, sexual behavior with various partners among HIV positive patients in Shenzhen before highly active anti-retroviral therapy, and to provide evidences for health education intervention. Methods: Questionnaire survey and information collection were carried out among HIV positive patients, under the informed consent, during the first physical examination before highly active anti-retroviral therapy. Results: The overall awareness rate of AIDS knowledge was 91%, 94.46% and 80.95% respectively for homosexual and heterosexual populations, with significant difference between the two groups (χ²=21.254, P<0.001). In addition, there were significant differences in the factors related to education, income, route of infection, marital status, residence and other related factors (P<0.05). In HIV positive MSM, primary sexual behavior occurred mainly at the age of less than 30 (96.8%) and in university or earlier stage (58.3%), college students as the first sexual partner accounted for 44.9%, and once used Rush accounted for 42.7%. There were significant differences in the number of temporary sexual partners and condom use frequency between homosexual and heterosexual subjects (P<0.05). Conclusions Individuals infected with HIV via different routes are variant on AIDS cognition. Health education on AIDS related knowledge and sexual security before and after antiviral treatment can not only improve the awareness rate of HIV/AIDS infection, but also can reduce the risk of the spread of HIV/AIDS.

OBJECTIVE:To observe therapeutic efficacy and safety of budesonide and formoterol in the treatment of acute exacerbation of mild to moderate asthma.METHODS:A total of 89 patients with acute exacerbation of mild to moderate asthma were randomized divded into study group (45 cases) and control group (44 cases).Study group was given Budesonide and formoterol dry powder inhalation,one inhalation,q6 h,gargling 5 times after inhalation,6 inhalation per day at most+Montelukast tablet 10 mg orally,once a day.Control group received Prednisone tablet 25 mg orally after breakfast,once a day,d1-5+Theophylline sustained-release capsule 0.2 g,twice a day+Montelukast tablet 10 mg,once a day in the evening.Both groups were treated for 5 d.Acute AQLQ score,FEV1,PEF％pred and SpO2 were observed in 2 groups before and after treatment,and the occurrence of ADR was recorded.RESULTS:Before treatment,there was no statistical significance in acute AQLQ score,FEV1,PEF％pred or SpO2 between 2 groups(P＞0.05).After treatment,acute AQLQ score,FEV1,PEF％pred and SpO2 of 2 groups were significantly higher than before treatment,with statistical significance (P＜0.05),but there was no statistical significance between 2 groups (P＞ 0.05).There was statistical significance in the incidence of ADR between 2 group(P＜0.05).CONCLUSIONS:Budesonide and formoterol can improve pulmonary ventilation function and prognosis in patients with acute exacerbation of mild to moderate asthma with good safety.
