ObjectiveTo investigate the effects of Xinfeng capsules combined with chronic disease management of traditional Chinese medicine (TCM) on rapid disease control and short-term prognosis of patients with rheumatoid arthritis (RA). MethodsA total of 80 RA patients hospitalized in the Department of Rheumatology of The First Affiliated Hospital of Anhui University of Chinese Medicine from January 2022 to March 2024 were enrolled and randomly divided into an observation group (40 cases) and a control group (40 cases). The control group was treated with conventional methotrexate combined with standard chronic disease management, while the observation group was additionally treated with Xinfeng Capsules combined with TCM chronic disease management. The treatment course lasted 24 weeks. The outcomes were compared between two groups, including disease activity [28-joint disease activity score (DAS28), clinical disease activity index (CDAI), simplified disease activity index (SDAI)], visual analogue scale (VAS) for pain, TCM syndrome score, tender joint count (TJC), swollen joint count (SJC), morning stiffness duration, Health Assessment Questionnaire (HAQ), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), American College of Rheumatology (ACR) 20%, 50% and 70% response rates (ACR20/50/70), erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hs-CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide antibody (CCP-Ab), interleukin (IL)-6, IL-1β, tumor necrosis factor-α (TNF-α), and serum immunoglobulin G (IgG). The Chronic Disease Self-Management Scale (CDSMS) was used to evaluate patients’ self-management ability, self-care ability, and nursing satisfaction. Patients were followed up for 12 weeks to assess prognosis, and COX regression analysis was performed to determine the impact on short-term prognosis. ResultsAfter treatment, TJC, SJC, morning stiffness duration, DAS28, CDAI, SDAI, VAS, TCM syndrome score, ESR, hs-CRP, RF, CCP-Ab, IL-6, IL-1β, TNF-α, IgG, HAQ, SAS, SDS, chronic disease self-management behavior, self-efficacy, and self-care ability all improved significantly in both groups compared with baseline (P<0.05,P<0.01). Compared with the control group, the observation group showed more significant improvements in TJC, SJC, morning stiffness duration, DAS28, CDAI, SDAI, VAS, TCM syndrome score, ESR, IL-1β, IgG, HAQ, SAS, SDS, self-care ability, chronic disease self-management behavior, and self-efficacy (P<0.05 or P<0.01). The ACR70 response rate and nursing satisfaction were significantly higher in the observation group than in the control group (P<0.01). COX regression analysis showed that Xinfeng capsules combined with TCM chronic disease management reduced the risk of poor short-term prognosis in RA patients. ConclusionXinfeng capsules combined with TCM chronic disease management facilitates rapid disease control in RA patients, effectively improves short-term prognosis, and plays an important role in the treatment of the disease.

This article reports the clinical features and gene mutation types of a large family with Nascimento form of syndromic X-linked intellectual developmental disorder (MRXSN), involving 9 individuals across 3 generations, and a literature review was conducted. In this family, 9 individuals had similar manifestations including mental retardation and unusual facies, and 4 of them had passed away. Genetic testing showed that the proband had the deletion of exons 2-3 of the UBE2A gene, which was inherited from the mother. Fluorescent quantitative polymerase chain reaction showed that the proband and his uncle had the deletion of exons 2-3 of the UBE2A gene; the proband's mother, grandmother, and great-aunt had a heterozygous deletion of exons 2-3 of the UBE2A gene; the proband's father, sister, and aunt had a normal copy number of exons 2-3 of the UBE2A gene. The 34 patients reported in the literature had diverse clinical phenotypes, and UBE2A gene mutations (22/34, 65%) and large fragment deletions (12/34, 35%) were the main mutation types. Moderate to severe mental retardation (34/34, 100%), speech and language impairment (33/34, 97%), and unusual facies (32/34, 94%) were the main clinical manifestations of MRXSN patients. The disease has obvious phenotypic heterogeneity, and early diagnosis facilitates optimal prenatal and postnatal management to improve reproductive outcomes.

Objective:To investigate the application of endoscopic ultrasound-guided liver biopsy (EUS-LB) to liver transplant recipients.Methods:In this retrospective cohort study, a total of 12 liver transplant recipients who underwent EUS-LB by the same endoscopist and specimens were diagnosed and reported by the same pathologist due to abnormal liver function or need to be evaluated for graft fibrosis in the Organ Transplantation Center of the Affiliated Hospital of Qingdao University were enrolled into the EUS-LB group from December 2021 to March 2022, meanwhile, a total of 23 patients whose PLB was completed by the same hepatologist and specimens were diagnosed by the same pathologist during the same period were enrolled in the PLB group. Acquisition of liver specimens and postoperative adverse events of the two groups were compared.Results:Patients in both groups were punctured 1-2 times on average, and the median total length of liver specimens in the EUS-LB group was significantly longer than that in the PLB group (61 mm VS 17 mm, Z=11.362, P=0.002). There was no significant difference in the length of the longest liver specimens between the two groups (17.6±6.9 mm VS 13.7±3.5 mm, t=2.382, P=0.086), while the number of liver specimens in the EUS-LB group was more than that in the PLB group (4.8±2.1 VS 2.3±1.2, t=9.271, P=0.001). The number of complete portal tracts was 11.3±4.6 in the EUS-LB group and 6.2±3.3 in the PLB group ( t=8.457, P=0.003). Abdominal pain was the only postoperative adverse event, and only 1 patient in the EUS-LB group had postoperative abdominal pain, which was fewer than that in the PLB group [8.3% (1/12) VS 43.5% (10/23), χ2=4.893, P=0.036]. Conclusion:Compared with PLB, EUS-LB delivers longer liver biopsy specimens with more complete portal tracts in liver transplant recipients, and fewer recipients complain about postoperative pain in EUS-LB group. Therefore, EUS-LB is a safer, more effective and more comfortable liver biopsy method.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System(BRICS)were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute(CLSI). WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period,9 035 strains of Gram-negative bacteria were collected from 51 hospitals,of which 7 895(87.4%)were Enterobacteriaceae and 1 140(12.6%)were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli( n=4 510,49.9%), Klebsiella pneumoniae( n=2 340,25.9%), Pseudomonas aeruginosa( n=534,5.9%), Acinetobacter baumannii complex( n=405,4.5%)and Enterobacter cloacae( n=327,3.6%). The ESBLs-producing rates in Escherichia coli, Klebsiella pneumoniae and Proteus spp. were 47.1%(2 095/4 452),21.0%(427/2 033)and 41.1%(58/141),respectively. The prevalence of carbapenem-resistant Escherichia coli(CREC)and carbapenem-resistant Klebsiella pneumoniae(CRKP)were 1.3%(58/4 510)and 13.1%(307/2 340);62.1%(36/58)and 9.8%(30/307)of CREC and CRKP were resistant to ceftazidime/avibactam combination,respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)complex was 59.5%(241/405),while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa(CRPA)was 18.4%(98/534). There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions,with statistically significant differences in the prevalence of CRKP and CRPA( χ2=20.489 and 20.252, P<0.001). The prevalence of CREC,CRKP,CRPA,CRAB,ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals( χ2=11.953,81.183,10.404,5.915,12.415 and 6.459, P<0.01 or <0.05),while the prevalence of CRPA was higher in economically developed regions(per capita GDP ≥ 92 059 Yuan)than that in economically less-developed regions(per capita GDP <92 059 Yuan)( χ2=6.240, P=0.012). Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend,and Escherichia coli is ranked in the top,while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different,and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.
