Objective To evaluate the survival of patients with diffuse large B-cell lymphoma(DLBCL)after chemotherapy using Fuzheng Jiedu Formula and to explore the intrinsic correlation between the lymphocyte subset level and the survival of patients with DLBCL.Methods A total of 234 patients with DLBCL who had completed chemotherapy and achieved complete or partial response in the Department of Hematology,Longhua Hospital Shanghai University of Traditional Chinese Medicine and Shanghai East Hospital,Tongji University from January 1,2013,to December 31,2023,were recruited.A cohort study design was adopted,with"whether to receive continuous Fuzheng Jiedu Formula treatment for≥6 months after chemotherapy"as the exposed factor.Patients meeting this exposed factor were divided into the traditional Chinese medicine(TCM)cohort,whereas those who did not meet this exposed factor were divided into the observation cohort.The 1-and 2-year progression-free survival(PFS)rate,overall survival(OS)rate,and duration of response(DOR)of the two cohorts were compared.The survival curves of PFS and OS of the two cohorts were drawn,and subgroup survival analysis was performed to determine factors affecting disease progression.The effect of Fuzheng Jiedu Formula on lymphocyte subset count level was observed.Results The study included 126 and 108 patients in the TCM and observation cohorts,respectively.Compared with the observation cohort,the 2-year PFS rate,2-year OS rate,and DOR were increased in the TCM cohort(P<0.05).The PFS in the TCM cohort was higher than that in the observation cohort[HR=0.542,95%CI(0.345-0.853),P<0.01].The result of subgroup analysis showed that PFS in the TCM cohort was higher than that in the observation cohort in the age≥60 years,AA stage Ⅲ-Ⅳ,CD4+

Following the principles of evidence-based medicine,in accordance with the structure and drafting rules of standardized documents,based on literature research,according to the characteristics of chronic cough in children and issues that need to form a consensus,the TCM Guidelines for Diagnosis and Treatment of Chronic Cough in Children was formulated based on the Delphi method,expert discussion meetings,and public solicitation of opinions.The guideline includes scope of application,terms and definitions,eti-ology and diagnosis,auxiliary examination,treatment,prevention and care.The aim is to clarify the optimal treatment plan of Chinese medicine in the diagnosis and treatment of this disease,and to provide guidance for improving the clinical diagnosis and treatment of chronic cough in children with Chinese medicine.

Objective:To investigate the clinical features and prognosis of hypertrophic cardiomyopathy（HCM）in children.Methods:The clinical data of 184 children diagnosed as HCM,who visited Beijing Children's Hospital of Capital Medical University from January 1，2006 to August 31，2022 were retrospectively analyzed.The children were divided into primary HCM group and secondary HCM group according to the etiology of HCM，and their clinical characteristics and prognosis were compared.Results:A total of 184 children[115（62.50%）males and 69(37.50%) females] with HCM were included.The median age at first diagnosis was 4.54（0.50，10.25）years.Among the participants，141（76.63%）cases had primary HCM，and 43（23.37%）cases had secondary HCM.Compared with the patients in primary HCM group，the patients in secondary HCM group had lower age of onset，with a higher proportion of the children under 1 year of age.Most cases had atypical symptoms，including a higher proportion of first-onset heart failure，higher proportion of enlarged cardiac shadow on chest radiograph，and lower left ventricular ejection fraction in the secondary HCM group（ P<0.05）.The proportion of older children，ratio of ventricular septal thickness to left ventricular posterior wall thickness，and the detection rate of left ventricular outflow tract obstruction in the primary HCM group was higher than those in patients with secondary HCM group（ P<0.05）.The survival curve for two groups showed that the secondary HCM group had significantly lower 1-year，2-year，3-year，5-year，and 10-year survival rates than those in the primary HCM group（ P<0.05）. Conclusion:The clinical manifestations of HCM in children are heterogenous due to different etiology，and it is necessary to actively clarify the etiology，improve risk assessment，and provide personalized management and treatment method.

Objective To explore the clinicopathological characteristics,prognosis and influencing factors of different pathological subtypes of gastric signet ring cell carcinoma(GSRC).Methods A retrospective analysis was performed on the clinical data of 232 patients with GSRC collected from January 2016 to December 2018 in Lanzhou University Second Hospital.According to the WHO classification criteria for GSRC,the patients were divided into pure gastric signet-ring cell carcinoma(pGSRC,n=36)and mixed gastric signet-ring cell carcinoma(mGSRC,n=196).The follow-up as of September 30,2022,the survival analysis was done using Kaplan-Meier method,the univariate and multivariate Cox regression were performed to analyze the risk factors affecting the prognosis of GSRC patients.Results The median survival time of pGSRC and mGSRC patients was 41.0(6.0-70.0)months and 24.0(2.0-74.0)months,respectively.Kaplan-Meier analysis showed that combination with diabetes,anemia,tumor diameter,nerve invasion,lymphovascular invasion,T stage,N stage,GSRC pathological subtype,CA125 and tumor diameter could affect the overall survival(OS)of patients with GSRC after radical gastrectomy(P＜0.05),but Her-2,whether adjuvant chemotherapy or not and others elements had no significant effect on OS of GSRC patients after radical gastrectomy(P＞0.05).Univariate Cox regression analysis showed that the combination with diabetes(P=0.031),anemia(P=0.028),tumor diameter＞5 cm(P=0.009),nerve invasion(P=0.002),lymphovascular invasion(P=0.002),mGSRC pathological type(P=0.039),T2-T4 stage(P=0.001),N1-N4 stage(P=0.004),pTNM stage Ⅲ(P=0.044),the number of lymph node metastasis＞30(P=0.044)and CA125 positive(P=0.009)were related to the prognosis of patients with GSRC after radical gastrectomy.Multivariate Cox regression analysis showed that mGSRC pathological type(P=0.035),T2-T4 stage(P=0.003),CA125 positive(P=0.010)were independent risk factors for poor prognosis of patients with GSRC after radical gastrectomy.Conclusion Compared with pGSRC,patients with mGSRC at diagnosis have higher pTNM stages,more aggressive,and shorter median survival time.mGSRC pathological type,T2-T4 stage,and CA125 positive were all independent factors affecting the prognosis of patients with GSRC.

Objective:To investigate the effects of compound Duzhong Jiangu Granules on joint function and gut microbiota in patients with Kashin-Beck disease.Methods:A single group pre- and post-experimental design was conducted, the patients with Kashin-Beck disease were selected as the subjects in Xunyi County, Xianyang City, Shaanxi Province; and treated with oral administration of compound Duzhong Jiangu Granules (12 g/bag, 1 bag/time, 3 times/day) for a period of 1 month. The improvement of joint function was evaluated using the joint dysfunction index scoring method before and after treatment. Morning stool samples of patients were collected and the changes in gut microbiota were analyzed before and after treatment using 16S rDNA sequencing technology.Results:A total of 87 patients with Kashin-Beck disease were included, including 44 males and 43 females; the age was (60.38 ± 7.12) years old, and the body mass index was (23.67 ± 3.59) kg/m 2. The comprehensive scores of joint dysfunction index for patients with Kashin-Beck disease before and after treatment were (7.27 ± 2.05) and (5.86 ± 2.01) points, respectively, and the difference was statistically significant ( t = 5.88, P < 0.001). The sequencing results of gut microbiota showed that there were statistically significant differences in the alpha diversity (chao1, observed species index) and beta diversity of gut microbiota in patients with Kashin-Beck disease before and after treatment ( Z = - 5.08, - 5.03, R = 0.09, P < 0.001). In the distribution of gut microbiota, Firmicutes was the dominant phylum, with relative abundances of 50.21% and 52.09% before and after treatment, respectively; the Bifidobacterium was the dominant bacterial genus, with relative abundances of 16.83% and 18.81% before and after treatment, respectively. At the genus level, a total of 17 gut microbiota genera were screened out, among which the relative abundances of Hafnia-Obesumbacterium, Gammaproteobacteria_unclassified, Acinetobacter, Pantoea, Leuconostoc, and Akkermanisia were significantly higher than before treatment ( Z = - 2.40, - 2.24, - 2.06, - 3.59, - 2.24, - 2.11, P < 0.05). The relative abundances of Dubosiella, Selenomonas, Anaeroplasma, Lachnospiraceae_ NK4A136_group, Rikenella, Prevotella, Megasphaera, Lactobacillus, Prevotella-9, Phascolarctobacterium, and Desulfovibrio were significantly lower than before treatment ( Z = - 9.38, - 2.61, - 2.18, - 8.43, - 2.45, - 2.46, - 2.49, - 7.29, - 2.29, - 2.55, - 2.08, P < 0.05). Conclusions:Compound Duzhong Jiangu Granules can effectively improve the joint function of patients with Kashin-Beck disease, and alter the diversity and richness of the gut microbiota community. It may reduce clinical symptoms in patients by regulating the structure of gut microbiota.

Objective To explore the molecular epidemiological characteristics of carbapenem-resistant Klebsiella pneumoniae(CRKP),and reveal its mechanism of resistance to ceftazidime/avibactam(CZA).Methods CZA-re-sistant CRKP strains initially isolated from the Affiliated Hospital of Xuzhou Medical University from January 2021 to September 2023 were collected.The carriage of 5 carbapenemase genes(blaKPC,blaNDM,blaOXA,blaVIM,blaIMp)were detected with gene amplification method and colloidal gold method.The relative copy number and expression level of Klebsiella pneumoniae(KP)carbapenemase-producing KP(KPC-KP)was detected with real-time quantita-tive polymerase chain reaction(RT-qPCR),mutation sites of KPC mutation strains were analyzed with whole-ge-nome sequencing,and epidemic characteristics of CRKP and resistance mechanism to CZA were analyzed.Results A total of 73 CZA-resistant CRKP strains were isolated,with 37(50.68％)being KPC and NDM co-producing strains,33(45.21％)NDM-producing alone(23 strains producing NDM-5 and 10 strains producing NDM-1),and 3 KPC-producing alone.KP-2842 strain was identified as ST11-type KPC-33 variant,KP-2127 and KP-2189 strains produced KPC-2.Compared with KP ATCC BAA-1705,the copy number of blaKPC in these strains up-regulated by 1.04-3.86 fold,and the expression increased by 6.66-12.93 fold,respectively.Colloidal gold and PCR methods demonstrated good consistency and the ability to detect the enzyme co-producing and KPC-33 variant.Conclusion In this hospital,the resistance of CRKP to CZA is primarily mediated by the metalloenzyme NDM,with co-produc-tion of NDM and KPC being a characteristic of CRKP.High copy number and expression level of blaKPC-2 also con-tribute to CZA resistance.This study identified the KPC-33 variant for the first time in ST11-type CRKP in Jiangsu Province.
