Following the core outcome set standards for development(COS-STAD), this study aims to construct core outcome set(COS) for clinical research on traditional Chinese medicine(TCM) treatment of simple obesity. Firstly, a comprehensive review was conducted on the randomized controlled trial(RCT) and systematic review(SR) about TCM treatment of simple obesity that were published in Chinese and English databases to collect reported outcomes. Additional outcomes were obtained through semi-structured interviews with patients and open-ended questionnaire surveys for clinicians. All the collected outcomes were then merged and organized as an initial outcome pool, and then a preliminary list of outcomes was formed after discussion by the working group. Subsequently, two rounds of Delphi surveys were conducted with clinicians, methodology experts, and patients to score the importance of outcomes in the list. Finally, a consensus meeting was held to establish the COS for clinical research on TCM treatment of simple obesity. A total of 221 RCTs and 12 SRs were included, and after integration of supplementary outcomes, an initial outcome pool of 141 outcomes were formed. Following discussions in the steering advisory group meeting, a preliminary list of 33 outcomes was finalized, encompassing 9 domains. Through two rounds of Delphi surveys and a consensus meeting, the final COS for clinical research on TCM treatment of simple obesity was determined to include 8 outcomes: TCM symptom scores, body mass index(BMI), waist-hip ratio, waist circumference, visceral fat index, body fat rate, quality of life, and safety, which were classified into 4 domains: TCM-related outcomes, anthropometric measurements, quality of life, and safety. This study has preliminarily established a COS for clinical research on TCM treatment of simple obesity. It helps reduce the heterogeneity in the selection and reporting of outcomes in similar clinical studies, thereby improving the comparability of research results and the feasibility of meta-analysis and providing higher-level evidence support for clinical practice.

The efficacy mechanism of the alcoholic extract of Gnaphalium affine was investigated by observing its influence on oxidative stress and intestinal flora in rats modeled for chronic obstructive pulmonary disease(COPD). UPLC-MS was used to evaluate the quality of the alcoholic extract of G. affine, and 72 rats were randomly divided into six groups, with COPD models established in five groups by cigarette smoke combined with airway drip lipopolysaccharide, and the rats were given the positive drug of Danlong Oral Solution, as well as low-, medium-, and high-doses alcoholic extract of G. affine, respectively. After two weeks of continuous gastric gavage, the body weights and general morphology observations were performed; HE staining and Masson staining were used to verify the effects of the alcoholic extract of G. affine on alveolar inflammation and collagen deposition area in COPD rats; the oxidative stress indexes CAT and GSH in serum and SOD and MDA in lung tissue of the rats were measured, and the mRNA expression of HO-1, Nrf2, and NQO1 were determined by qRT-PCR. The protein expressions of HO-1, Nrf2, and NQO1 were determined by the Western blot method, and the mechanism by which the alcoholic extract of G. affine affected oxidative stress in COPD rats was explored. Finally, the influence of G. affine on the changes in intestinal flora caused by COPD was studied by 16S rRNA sequencing. The results showed that a total of 121 chemical components were identified by UPLC-MS, including 70 positive and 51 negative ion modes. In animal experiments, it was found that the alcoholic extracts of G. affine were able to reduce the percentage of collagen deposition, affect the oxidative stress indexes such as CAT, GSH, SOD, MDA, as well as the mRNA and protein expression of Nrf2, HO-1, and NQO1. The 16S rRNA sequencing results showed an increase in the level of Lactobacillales and a decrease in the level of Desulfovibrio and Desulfovibrionales, suggesting that the alcoholic extracts of G. affine could reverse the changes in intestinal flora caused by COPD. In conclusion, the alcoholic extracts of G. affine may exert anti-COPD effects by affecting the oxidative stress pathway and modulating the changes in intestinal flora.

OBJECTIVE: To investigate the clinical characteristics and prognosis of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). METHODS: Clinical data of 10 patients with PTCL-NOS in Gansu Provincial Hospital from May 2016 to June 2023 were collected. The treatment outcomes were evaluated, and the factors affecting prognosis were analyzed. RESULTS: The median age of onset for the 10 patients was 60.7 (47-75) years, with 7 males and 3 females. Nine cases received chemotherapy, while one case died suddenly after diagnosis, and the median course of chemotherapy was 6.9 (1-13) courses. Assessing the efficacy, 3 patients achieved complete remission (CR) while 7 patients showed progression. Age, sex, lactate dehydrogenase (LDH) level, Ki-67 and the presence of hemophagocytic lymphohistocytosis (HLH) were not statistically correlated with CR rate ( P >0.05). Patients with IPI score 3-5, and Ann Arbor stage III-IV had statistically lower CR rates (both P <0.05). Age, B symptoms, LDH level ,hemoglobin, Ki-67 index and PLR value were not statistically correlated with overall survival (OS) time ( P >0.05). Male, platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, presence of HLH, NLR≥4.05, and LMR <2.81 were statistically correlated with shorter OS (all P <0.05). Among the 10 patients, 3 cases have survived and are still in CR status, while 7 cases have died, with a median survival time of 7.5 (1-85) months. CONCLUSIONS Patients with IPI score 3-5 and Ann Arbor stage III-IV have low CR rate and poor prognosis. The OS of patients who are male, with platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, complication of HLH, NLR≥4.05, and LMR <2.81 is short, and prognosis is poor.

OBJECTIVE: To study the characteristics of a novel variant of the α-1,3-N-acetylgalactosaminyltransferase gene in a family through serological and gene sequence analyses of a proband with ABO subtype and her family members. METHODS: Blood samples of the proband and four family members were collected. The ABO phenotypes were detected by serological methods, and the ABO blood group genotyping was performed by fluorescence PCR. Direct sequencing was carried out for exons 1-7 of the ABO gene in the proband and family members, and cloning sequencing was conducted for exons 6 and 7. RESULTS: The serological test showed that the blood group phenotype of the proband was Ael type, and the ABO blood group genotyping result was A/O. Sequencing results indicated that on the basis of the ABO*A1.01 sequence, there were simultaneous variations of c.467C>T and c.664G>A in exon 7 of the A allele, which belonged to a novel variation of the A allele and had been registered in GenBank with the accession number MZ076784.1. Family investigation revealed that the proband, her son and granddaughter all had this novel variation. CONCLUSION On the basis of the ABO*A1.01 sequence, the new variation of the combination of c.467C>T and c.664G>A in exon 7 is a heritable variation. It is speculated that this variation is the cause of the weakened expression of the A antigen.

Aim To investigate the role of corylin in angiotensin Ⅱ(Ang Ⅱ)-induced cardiomyocyte hy-pertrophy and its underlying mechanisms.Methods An Ang Ⅱ-induced cardiomyocyte hypertrophy model was established and treated with corylin.Real-time PCR was employed to assess hypertrophic gene mRNA expression,and immunofluorescence was used to meas-ure cardiomyocyte surface area.Western blot and en-zyme activity assay kits were used to evaluate SIRT1 expression and activity.Results Corylin markedly mitigated Ang Ⅱ-induced hypertrophic gene expression and cardiomyocyte surface area enlargement.Moreo-ver,it prevented the Ang Ⅱ-mediated decline in SIRT1 protein levels and deacetylase activity.Further investi-gation indicated that corylin inhibited Ang Ⅱ-driven NF-κB transcriptional activity and the expression of its downstream target genes,such as TNF-α,IL-6,and IL-1β.Notably,SIRT1 silencing abolished the protective effects of corylin against cardiomyocyte hypertrophy,as well as its regulation of the SIRT1/NF-κB signaling pathway.Conclusion Corylin suppresses cardiomyo-cyte hypertrophy by modulating the SIRT1-dependent NF-κB signaling pathway.

The study aims to investigate the effects of adding different proportions of Codonopsis radix compound crude extracts to the rabbit diet on growth performance,immune status,intesti-nal enzyme activity,structure,and microbial composition.A total of 96 5-week-old New Zealand White rabbits were randomly divided into 4 groups,with 6 replicates per group.The control group(BC)was fed a basal diet,while the experimental groups(CM-H and CM-L)were fed a basal diet supplemented with 1 000 mg/kg and 500 mg/kg of Codonopsis radix compound crude extracts,re-spectively.The antibiotic group(CK)was fed a basal diet supplemented with 300 mg/kg of keto-tifen.The experimental period was 42 days.Blood samples were collected at days 21 and 42,and se-rum biochemical and immune markers were determined.Intestinal segments and contents were col-lected at day 42 for analysis of intestinal health.The results showed that compared with the BC group,the average daily gain,feed-to-gain ratio,and diarrhea rate were significantly higher(P＜0.05)in the CM-H and CM-L groups.The total cholesterol(Tchol)content in the serum was sig-nificantly lower in the CM-H group at day 21 and the CM-L group at day 42(P＜0.05).The high-density lipoprotein(HDL)was significantly higher in the CM-H and CM-L groups than in the CK group at day 42(P＜0.05),and the total protein(TP)in the serum was significantly higher in the CM-H and CM-L groups than in the BC group(P＜0.05).The IgG and IgM levels in the serum were significantly higher in the CM-H and CM-L groups than in the BC group(P＜0.05).In the CM-H and CM-L groups,the content of acetic acid in the colon was significantly higher than that in the BC group(P＜0.05).The content of propionic acid in the colon of the CM-L group was also significantly higher than that in the BC group(P＜0.05).The content of α-amylase in the duode-num,the content of trypsin in the duodenum,the pancreas,and the ileum of the CM-H group were significantly higher than those in the BC group(P＜0.05),and the content of trypsin in the duode-num of the CM-H group was significantly higher than those in the BC group and the CM-L group(P＜0.05).Compared with the BC group,the content of GPX1 in the ileum and jejunum of the CM-L group and the ileum of the CM-H group was significantly increased(P＜0.05),and the length of the villi in the duodenum of the CM-H group was significantly increased(P＜0.05).Compared with the BC group,the expression level of ZO-1 in the ileum of the CM-H group was significantly upregulated(P＜0.05),and the expression level of Claudin in the jejunum of the CM-H group and the CM-L group was significantly higher than that in the CK group(P＜0.05).The high-throughput sequencing results showed that the Sob index was significantly higher in the CM-L group compared to the BC group(P＜0.05).At the phylum level,the Firmicutes and Bacteroid-ota phyla were the main phyla.At the genus level,Akkermansia and Ruminococcus were the main genera.The relative abundance of Papillibacter and Eubacterium_ruminantium_group in the CM-L group was significantly higher than that in the CK group(P＜0.05).In summary,adding a Codonopsis radix compound crude extract to the diet can improve the growth performance,immu-nity,antioxidant capacity,integrity of intestinal mucosal structure,enzyme activity in the intestine,and increase the diversity of microorganisms in the blind intestine when the diet is supplemented with 500 mg/kg of Codonopsis radix compound crude extract.

OBJECTIVE The aim of the study was to investigate and analyze the resource allocation and surveillance status of hospital-associated infections in secondary and above healthcare facilities in Anhui province.METHODS Secondary and above healthcare institutions in 16 cities were selected in Mar.2023 by convenient sampling meth-od,and self-designed questionnaire was administered by'wenjuanxing'to investigate the characteristics of health-care facilities,the management and surveillance of hospital-acquired infections.RESULTS A total of 302 medical facilities,including 88 tertiary and 195 comprehensive facilities,completed the survey.All tertiary healthcare fa-cilities set up the independent departments for hospital-associated infections,while 12.15%of secondary health-care facilities did not.Totally 17.22%of healthcare facilities did not meet the standard requirements of ratio of full-time equivalents to beds,while the unqualified rate of tertiary healthcare facilities(25.00%)was higher than that of secondary healthcare facilities(14.02%).The full-time equivalents were mainly in nursing(64.89%),and relatively insufficient in other specialties.All tertiary healthcare facilities had carried out comprehensive surveil-lance,however,secondary healthcare facilities still needed to be improved.The allocation ratio of surveillance in-formation for system hospital-associated infection was 37.42%in tertiary healthcare facilities,but only 18.69%in secondary.CONCLUSIONS The hospital-associated infection management system of certain healthcare facilities in Anhui province still calls for improving,more personnel numbers and specialties are required.Besides,the con-struction of information system urgently needs to be strengthened.At the same time,more attention should be paid to secondary healthcare facilities,which should be supplied for more resources,carry out basic monitoring work to reduce hospital-associated infections and ensure patients'safety.

OBJECTIVE To evaluate the changes in monitoring indicators related to healthcare-associated infections(HAIs)management in Anhui Province in 2018 and 2022,to provide a scientific basis for optimizing HAI control strategies.METHODS A cross-sectional survey was conducted in 2019 and 2023 across 48 secondary and tertia-ry medical institutions,HAI data were collected and analyzed.RESULTS The two-year averages of monitoring indi-cators were as follows:the incidence rate of HAIs was 0.66％,the prevalence rate of HAIs was 1.69％,the inci-dence rate of surgical site infection for class I incisions was 0.20％,the antibiotic usage rate was 44.59％,the pathogen detection rate for therapeutic antibiotics was 43.76％,the incidence rate of catheter-related blood-stream infection(CRBSI)was 0.64‰,the incidence rate of ventilator-associated pneumonia(VAP)was 5.81‰,and the incidence rate of catheter-associated urinary tract infection(CAUTI)was 0.79‰.By 2022,significant im-provements were observed in most indicators(P＜0.05).Compared to tertiary hospitals,secondary hospitals ex-hibited low rates of hospital infection incidence,prevalence,class I incision infections,antibiotic utilization and CRBSI,but high rates of VAP and CAUTI(P＜0.05).CONCLUSIONS Significant improvements have been made in monitoring indicators related to HAI managements in Anhui Province.However,secondary hospitals still need to enhance their capabilities of monitoring indicators and detecting pathogens.
