Objective To evaluate the clinical efficacy of traditional Chinese medicine turbid phlegm obstructing lung decoction on patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)and its influence on laboratory indexes.Methods A total of 191 patients with AECOPD who were hospitalized in the First People's Hospital of Changde from January 2021 to December 2022 were selected.Patients were divided into observation group(96 cases)and control group(95 cases)according to their treatment intention.The control group received conventional treatment of western medicine,and the observation group received oral administration of traditional Chinese medicine turbid phlegm obstructing lung decoction for one week.TCM symptom scores,COPD assessment test(CAT),lung function,laboratory indicators and efficacy were compared between two groups.Results The total effective rate of observation group was significantly higher than that of control group(χ2=4.573,P=0.030).After treatment,TCM symptom score,CAT score,hypersensitive C-reaction protein(hsCRP)and interleukin-6(IL-6)of patients in both groups were significantly lower than before treatment,percentage of forced vital capacity to predicted value(FVC%)and percentage of forced expiratory volume in one second to predicted value(FEV1%)were significantly higher than before treatment(P<0.05),arterial partial pressure of carbon dioxide(PaCO2)of observation group was lower than before treatment,and arterial partial pressure of oxygen(PaO2)was higher than before treatment(P<0.05).The TCM symptom score,CAT score,hsCRP and IL-6 of observation group were significantly lower than those of control group,while FVC%,FEV1%and PaO2 were significantly higher than those of control group(P<0.05).Conclusion On the basis of western medicine treatment,traditional Chinese medicine turbid phlegm obstructing lung decoction can more effectively improve clinical symptoms of AECOPD patients,relieve the inflammation in the body,contribute to the recovery of lung function and improve the quality of life of patients.

Objective: To investigate the difference in influencing factors for diabetes between urban and rural residents in Hefei City, so as to provide the basis for control and research of diabetes. Methods: The residents aged 18 years and older were selected using the stratified multistage random sampling method from 5 districts (counties) in Hefei City from August to December 2021. Demographic information, smoking, self-rated health status and sleep duration were collected through questionnaire surveys. Height, body weight and fasting blood glucose were measured. The crude prevalence of diabetes was calculated and standardized by age using China Statistical Yearbook 2022. Factors affecting diabetes were identified using a multivariable logistic regression model. Results: Totally 10 443 residents were investigated, including 6 386 urban residents (61.15%) and 4 057 rural residents (38.85%). There were 4 690 males (44.91%) and 5 753 females (55.09%). Diabetes were detected in 1 492 cases, with a standardized prevalence of 9.57%. The standardized prevalence of diabetes among urban and rural residents were 9.21% and 12.58%, respectively, and the difference was statistically significant (P<0.05). Multivariable logistic regression analysis showed that region, age, educational level, occupation, body mass index and self-rated health status were influencing factors for diabetes. Further analysis stratified by urban and rural area showed that, in addition to the above factors, gender and smoking were influencing factors for diabetes among urban residents, while sleep duration was the influencing factor for diabetes among rural residents (all P<0.05). Conclusions There are urban-rural differences in the prevalence of diabetes among residents in Hefei City, and the prevalence of diabetes is associated with age, educational level, occupation, body mass index and self-rated health status.

Objective To study the quality comparability of human coagulation factor Ⅷ(FⅧ)produced before and after the change of factory site.Methods A comparative study was carried out on quality quantitative indexes,related im-purities and stability data of FⅧ produced before and after the change of factory site.Results The FⅧ quantitative quality before and after the change of factory site all met the quality standard,and the related impurities including aluminum resi-due,tributyl phosphate residue,polysorbate 80 residue and PEG residue all met the quality standard.Other impurities in-cluding human fibrinogen,fibronectin,plasminogen,IgA,IgM and IgG were extremely low in content and equivalent in quality.The content of VWF(von Willebrand factor)had no obvious change before and after the change of factory site,but was significantly higher than that of other domestic manufacturers'commercial products.The results of accelerated stability and long-term stability tests showed that the titer of FⅧ fluctuated within the methodological error range,and the results all met the quality standard.Conclusion The change of factory site of FⅧ has no effect on the quality.

Objective To investigate the protective effect of total saponins of Panax japonicus(TSPJ)against CCl4-induced acute liver injury(ALI)in rats and explore the underlying pharmacological mechanisms.Methods Male SD rat models of CCl4-induced ALI were given intraperitoneal injections of distilled water,100 mg/kg biphenyl bisabololol,or 50,100,and 200 mg/kg TSPJ during modeling(n=8).Liver functions(AST,ALT,TBil and ALP)of the rats were assessed and liver pathologies were observed with HE staining.Immunohistochemistry was used to detect the expressions of PI3K/Akt/NF-κB signaling pathway molecules in liver tissue;ELISA was used to determine the levels of T-SOD,GSH-Px,and MDA.Western blotting was performed to detect the expression levels of PI3K-Akt and SIRT6-NF-κB pathways in the liver tissue.Results Network pharmacological analysis indicated that the key pathways including PI3K/Akt mediated the therapeutic effect of TSPJ on ALI.In the rat models of ALI,treatments with biphenyl bisabololol and TSPJ significantly ameliorated CCl4-induced increase of serum levels AST,ALT,ALP,TBil and MDA and decrease of T-SOD and GSH-Px levels(all P<0.01).The rat models of ALI showed significantly increased expression of p-NF-κB(P<0.01),decreased expressions of PI3K,p-Akt and SIRT6 proteins,and elevated expression levels of p-NF-κB,TNF-α and IL-6 proteins in the liver,which were all significantly improved in the treatment groups(P<0.05 or 0.01).Conclusion TSPJ can effectively alleviate CCl4-induced ALI in rats by suppressing inflammatory responses and oxidative stress in the liver viaregulating the PI3K/Akt and SIRT6/NF-κB pathways.

Objective To investigate the composition of symptom clusters in early postoperative breast cancer patients and analyze the sentinel symptoms of each cluster of symptoms. Methods A total of 309 patients who underwent mastectomy were conveniently sampled and surveyed using the Chinese version of the Anderson Symptom Inventory. Principal component analysis and varimax orthogonal rotation were employed to analyze the symptom clusters, and their associations were analyzed using the Apriori algorithm model to identify the sentinel symptoms of each cluster of symptoms. Results Three symptom clusters were identified in early postoperative breast cancer patients: neuro-sleep symptom cluster [fatigue (weakness)-distress-pain-sleepiness-restless sleep], sensory-perception symptom cluster (numbness-forgetfulness-shortness of breath-sadness-dry mouth), and digestive system symptom cluster (nausea-vomiting-loss of appetite). Fatigue was the sentinel symptom of the neuro-sleep symptom cluster, numbness was the sentinel symptom of the sensory-perception symptom cluster, and nausea was the sentinel symptom of the digestive system symptom cluster. Conclusion Early postoperative breast cancer patients experience multiple symptom clusters, with sentinel symptoms existing in each cluster. Healthcare staff should develop intervention measures based on sentinel symptoms to improve the efficiency of symptom management and reduce the degree of symptom distress for patients.

Objective:To isolate and culture WU polyomavirus (WUPyV), and to analyze the genome-wide evolutionary patterns, homology and population dynamics.Methods:Real-time quantitative PCR was used to detect the nasopharyngeal aspirate samples of hospitalized children with respiratory tract infection in Beijing Friendship Hospital during 2020 to 2022. Primary human airway epithelial cells cultured at the air-liquid interface were used to isolate and culture WUPyV. Whole genome sequence of the isolated strain was obtained by Sanger sequencing. For phylogenetic and evolutionary dynamics analysis, the whole genome was compared with the published whole genome sequences in GenBank database.Results:The detection rate of WUPyV was 4.7% (31/659) during 2020 to 2022, and a clinical strain BJ0593 of WUPyV type Ⅲc was successfully isolated. The homology of the whole genome and gene fragments of WUPyV was high. The average evolutionary rate of VP2 gene was about 1.256×10 -4 substitution/site every year, and the population dynamics of WUPyV tended to be flat in the last decade. Conclusions:This study successfully isolated a clinical WUPyV type Ⅲ strain for the first time, which provided the basis for further investigation on the molecular evolution and pathogenicity of WUPyV.

Objective:To analyze the characteristics of adults (non-pregnant women) infected with Listeria monocytogenes and to provide evidence for diagnosis and treatment of this disease. Methods:Patients admitted in West China Hospital of Sichuan University between January 2008 and April 2020 with Listeriadisease were enrolled in this study. The clinical data of patients including age, symptoms, underlying diseases and prognosis, as well as the laboratory results of WBC, neutrophil ratio (N%), procalcitonin (PCT), interleukin-6 (IL-6) and C-reactive protein (CRP), were obtained for analyzing the clinical infection and prognosis characteristics of the patients. Results:A total of 57 patients were included, patients were 18-83 (52.8±15.9) years old, percent of over 60 years old patients accounted for 35.09% (20/57). The incidence rate in summer season was the highest (45.61%, 26/57). There were 48 cases with comorbidities, sepsis occurred in 31 cases and meningitis in 18 cases. The time of diagnosis of Listeriosis was (6.1±2.9) days. After diagnosis, the target therapy was applied: such as carbapenem (26.32%, 15/57) and penicillins (22.81%, 13/57). The levels of WBC (6.77 [2.99, 9.54]×10 9/L vs 10.23 [6.71, 16.55]×10 9/L), NLR (3.07 [1.66, 8.16] vs 11.26 [5.66, 20.08]) and CRP (40.7 [16.9, 91.9] g/L vs 92.8 [59.9, 142.7] g/L) were significantly lower after treatment than those before treatment in 47 hospitalized patients (all P<0.05). Thirty-eight patients were treated according to the guidelines, 33 cases improved, 2 cases had poor prognosis and 2 cases died. Conclusion:The main risk factors of Listeria monocytogenes infection in adults (non-pregnant women) are underlying diseases, especially autoimmune diseases and pulmonary infections. Penicillins can be used as the first choice for empirical therapy. Carbapenems and erythromycin serve as the combination medications during the full course of treatment.

Objective: To compare the reliability of Internet Addiction Impairment Index (IAII), Revised Chen Internet Addiction Scale(CIAS-R)-Taiwan Revision, CIAS-R-Mainland Revision, Young Diagnostic Questionnaire (YDQ) and the consistency of Internet addiction using the four scales in college students. Methods: A total of 1 004 undergraduates from 3 universities in Hefei were selected to measure the tendency of internet addiction simultaneously using the four scales, and 122 students were re tested two weeks after the initial assessment. Correlation coefficient, coincidence rate and Kappa value were used to analyze the consistency of the four scales. Analysis of variance, t test and Logistic regression were used to determine the consistency of the factors related to internet addiction scale. Results: The reliability of the four Internet addiction scales were greater than 0.7( P <0.01). The correlation coefficient among all scales was greater than 0.5( P <0.01). The agreement between YDQ and CIAS-R-Mainland Revision was 0.87. The Kappa value of YDQ and CIAS-R-Taiwan Revision in the consistency analysis was 0.51( P <0.01), the Kappa value between the other scales was less than 0.5. Results showed that the four scales were consistent in Internet addiction prevalence by gender, grade and major, while CIAS-R-Taiwan Revision and YDQ were not consistent with the other two scales in sleep disorder. Conclusion The four Internet addiction scales all have good reliability, while low agreement in Internet addiction assessment, suggesting further improvement and revision in Internet addiction scales.
