BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Against the backdrop of frequent regional conflicts and natural disasters worldwide，emergency medical rescue for mass casualty events faces significant challenges. To address critical issues such as rapid triage for polytrauma，optimization of treatment strategies，and determination of intervention priorities，the International Trauma Medicine Community has established multiple trauma scoring systems to guide clinical decision-making. Intelligent portable ultrasound，leveraging its technical advantages of lightweight portability，non-invasiveness，safety，and real-time imaging，demonstrates increasingly prominent clinical value in prehospital trauma assessment. This study systematically reviews relevant literature from the past two decades，summarizing advancements in the application of intelligent portable ultrasound within prehospital emergency care and disaster medicine. Based on research focus considerations，this paper specifically examines the diagnostic efficacy and clinical value of this technology across three core domains：chest trauma，abdominal trauma，and musculoskeletal trauma.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Aim To explore the mechanism of Bushen Tongfu prescription(BSTF)regulating gut microbiota and improving learning and memory ability of Alzhei-mer's disease(AD)model mice.Methods APP/PS1 mice were administered by BSTF for eight weeks.The spatial learning and memory ability of mice were detected by Morris water maze.The changes in the gut microbiota abundance and diversity of mice were detec-ted by 16S rDNA technology.The morphological chan-ges of hippocampus were observed by HE staining.The expression of the activation of microglia in hippocampus was detected by immunofluorescence.The expressions of pro-inflammatory factors of TLR4,NF-κB and IL-6 in brain tissue were detected by Western blot.Results Compared with the model group,the escape latency and swimming path were shortened,the times of target crossings after removing the platform increased in BSTF groups(P＜0.05),the α-diversity increased and the abundance of gut microbiota was regulated,the mor-phological structure and pathological damage of hipp-ocampal cells were improved,the co-expression of iN-OS/Iba1 decreased and the co-expression of Arg1/Iba1 increased significantly(P＜0.01),the transformation of M1 to M2 of microglial cells was promoted,and the expression of TLR4,NF-κB and IL-6 protein decreased significantly.Conclusions BSTF can improve the learning and memory ability of APP/PS1 mice,and its mechanism may be related to regulating the gut micro-biota and the LPS/TLR4/NF-κB pathway,inhibiting the activation of pro-inflammatory microglia,reducing inflammation in hippocampus and improving the patho-logical damage of hippocampal cells.

Objective:In accordance with the urban spatial structure and functional positioning outlined in the General Plan for the Overall Urban Development of Beijing(2016-2035),this study analyzed the allocation and equity of human resources in the Beijing Center for Disease Control and Prevention(CDC)system from 2019 to 2023,aiming to provide a reference for future planning.Methods:Based on the Plan,Beijing was divided into five structural regions.Descriptive statistical analysis,the Gini coefficient,and the Theil index were used to comprehensively evaluate the allocation and equity of regional human resources.Results:From 2019 to 2023,the total number of human resources in the Beijing CDC system showed a slow growth trend,with an overall shortage in staffing;however,the quality structure of personnel was relatively good.Equity among the structural regions gradually improved,as indicated by the annual decrease in both the Gini coefficient and the total Theil index.The contribution of inter-group differences to the total Theil index was greater than that of intra-group differences.Conclusions:There is a certain gap between the current human resource allocation in the Beijing CDC system and the requirements of non-capital function relocation and functional positioning of each structural region.It is recommended to align with urban planning,increase the number of personnel performing public health functions,and establish human resource allocation standards,plans,and working mechanisms that meet the development needs of each structural region,thereby better serving the functional positioning of the capital city and the health of its residents.

Objective:To investigate lymph node metastasis(LNM)in the prostatic anterior fat pad(PAFP)of PCa patients after robot-assisted radical prostatectomy(RARP),and analyze the clinicopathological features and prognosis of LNM in the PAFP.Methods:We retrospectively analyzed the clinicopathological data on 1 003 cases of PCa treated by RARP in the Department of Urolo-gy of PLA General Hospital from January 2017 to December 2022.All the patients underwent routine removal of the PAFP during RARP and pathological examination,with the results of all the specimens examined and reported by pathologists.Based on the pres-ence and locations of LNM,we grouped the patients for statistical analysis,compared the clinicopathological features between different groups using the Student's t,Mann-Whitney U and Chi-square tests,and conducted survival analyses using the Kaplan-Meier and Log-rank methods and survival curves generated by Rstudio.Results:Lymph nodes were detected in 77(7.7％)of the 1 003 PAFP samples,and LNM in 11(14.3％)of the 77 cases,with a positive rate of 1.1％(11/1 003).Of the 11 positive cases,9 were found in the upgraded pathological N stage,and the other 2 complicated by pelvic LNM.The patients with postoperative pathological stage≥T3 constituted a significantly higher proportion in the PAFP LNM than in the non-PAFP LNM group(81.8％[9/11]vs 36.2％[359/992],P=0.005),and so did the cases with Gleason score ≥8(87.5％[7/8]vs 35.5％[279/786],P=0.009).No statisti-cally significant differences were observed in the clinicopathological features and biochemical recurrence-free survival between the pa-tients with PAFP LNM only and those with pelvic LNM only.Conclusion:The PAFP is a potential route to LNM,and patients with LNM in the PAFP are characterized by poor pathological features.There is no statistically significant difference in biochemical recur-rence-free survival between the patients with PAFP LNM only and those with pelvic LNM only.Routine removal of the PAFP and inde-pendent pathological examination of the specimen during RARP is of great clinical significance.
