Obesity is a major global public health challenge and a leading cause of multiple metabolic disorders,including hypertension and diabetes.In China,more than half of the adult population is overweight or obese.While anti-obesity pharmacotherapies(such as GLP-1 receptor agonists)and bariatric surgery have both advanced rapidly,strategies for integrating these two modalities remain unclear.In particular,controversies persist regarding surgical eligibility after drug discontinuation,and standardized clinical guidelines are lacking.In July 2025,the International Federation for the Surgery of Obesity and Metabolic Disorders released the world's first statement focusing on"metabolic bariatric surgery after pharmacotherapy-induced weight loss",which emphasizes the chronic disease model of obesity management and clarifies the synergistic relationship between pharmacotherapy and surgery.This article interprets the statement from the perspectives of treatment strategies,surgical eligibility,and drug-surgery coordination,aiming to provide evidence-based reference for clinicians and to promote standardized,integrated obesity management.

Objective:To evaluate the clinical efficacy of"Shibao Decoction"in the management of late-onset hypogonadism(LOH)caused by deficiency of kidney essence.Methods:Sixty male patients with late-onset hypogonadism of kidney essence defi-ciency type were randomly assigned to the treatment group and the control group,each with 30 cases.The patients in treatment group were treated with oral Shibao Decoction,while the control group was treated with oral Testosterone Undecanoate Capsules.The patients in both groups were treated for 12 weeks.The PADAM symptom score,TCM syndrome score,serum total testosterone(TT),serum free testosterone(FT),sex hormone binding globulin(SHBG),body mass index(BMI),total skeletal muscle mass index(SMI),appendicular skeletal muscle mass index(ASMI),FBG,FINS,and insulin resistance index(HOMA-IR)levels were compared be-tween the two groups.Results:After treatment,PADAM scores for each item and TCM symptoms score decreased,TT and FT in-creased in both groups,all with statistically significant differences from those of pre-treatment(P＜0.05).The level of SHBG in the control group decreased(P＜0.05),which had not changed significantly in the treatment group(P＞0.05).After treatment,SMI and ASMI increased in both groups significantly(P＜0.05).BMI decreased in the control group(P＜0.05),which had not changed significantly in the treatment group(P＞0.05).The level of FINS decreased in the control group(P＜0.05),which had not changed significantly in the treatment group(P＞0.05).FPG had not changed significantly in both groups(P＞0.05),and the insulin resist-ance index(HOMA-IR)had significantly improved in both groups,all with statistically significant differences from those of pre-treat-ment(P＜0.05).After treatment,the total effective rates of PADAM score and TCM syndrome score in the treatment group were 73.3％and 86.6％respectively,and the total effective rates in the control group were 66.7％and 76.6％respectively.The total ef-fective rates of the two scores in the treatment group were slightly higher than those in the control group(P＞0.05).There was no sig-nificant difference in the indicators between the two groups after treatment,and the treatment group is generally comparable with the control group in the therapeutic effects(P＞0.05).And no adverse reactions occurred during treatment in both groups.Conclu-sion:The"Shibao Decoction"has a remarkable therapeutic effect on late-onset hypogonadism caused by deficiency of kidney essence and has good safety.It can be used as an alternative to testosterone undecanoate and is worthy of clinical promotion and application.

Background and Aims:Gastroesophageal reflux disease(GERD)is a common complication following sleeve gastrectomy(SG),particularly in patients with concomitant hiatal hernia,where symptoms tend to be more persistent and refractory,significantly impairing postoperative quality of life.This study aimed to evaluate the efficacy of laparoscopic hiatal hernia repair combined with gastroesophageal fixation in SG patients with severe GERD and hiatal hernia,providing clinical reference for revisional surgical strategies.Methods:The clinical data of 9 patients with severe GERD after SG who underwent laparoscopic hiatal hernia repair and gastroesophageal fixation at Huashan Hospital,Fudan University,between January 2023 and June 2024 were retrospectively analyzed.GerdQ scores,proportion of endoscopically confirmed reflux esophagitis,and proton pump inhibitor(PPI)usage were compared before and after surgery.Surgical parameters and follow-up outcomes were also recorded.Results:All patients successfully completed the surgery without major intraoperative complications,and the mean postoperative hospital stay was 5.22 d.After a mean follow-up period of 15.27 months,the GerdQ score significantly decreased from 11.67±2.00 to 7.22±1.48.The proportion of patients with GerdQ score≥8 decreased from 100.00％to 44.44％,and the rate of endoscopically confirmed GERD dropped from 88.89％to 11.11％;PPI use also significantly declined,with all differences reaching statistical significance(all P＜0.05).Conclusion:Laparoscopic hiatal hernia repair combined with gastroesophageal fixation can effectively alleviate reflux symptoms in SG patients with coexisting hiatal hernia,demonstrating favorable short-term efficacy and high safety.This approach may be a preferable surgical option for selected patients.

Gene editing technology utilizes artificial nucleases to insert, replace, or delete specific sequences in desired genomic regions. The discovery of CRISPR/Cas9 nucleases was a milestone in the development of advanced gene editing tools, which revolutionized the field due to their simplicity and versatility. However, the limited precision of Cas9 nucleases remains a notable obstacle. Recently, derivative technologies such as prime editing have earned considerable attention for their enhanced efficiency and precision. The prime editing system consists of two components: the SpCas9 nickase (H840A) fused with reverse transcriptase (MLV-RT) and an engineered prime editing guide RNA (pegRNA). This system can irreversibly introduce various types of genetic changes into the genome, including 12 possible types of point mutations, as well as insertions, deletions and their combinations, without the need for DNA double-strand breaks (DSBs) or donor DNA templates. Prime editing offers several advantages in terms of editing accuracy, versatility, PAM constraints, and off-target effects. The editing results of prime editing system is highly accurate and can be tailored to specific needs. In addition, the system can be edited near or far from PAM sites, making it less constrained by PAM site restrictions. Moreover, it demonstrates high genome-wide specificity. The system also supports a variety of edits, demonstrating immense potential, especially in large DNA fragment editing—an area that relied heavily on CRISPR/Cas9 nucleases before. The development of prime editing, especially bi-direction prime editor, shed new light on large DNA fragment manipulations, including deletions, insertions, replacements, gene integration, as well as chromosomal translocations, inversions, and tandem duplications. Despite the significant progress made with prime editing technology, its application still faces challenges, especially low editing efficiency, which limits its potential in broader research and clinical settings. Consequently, researchers are exploring strategies to enhance the efficiency of prime editing. This review highlights several approaches to improving prime editing efficiency. These include optimizing pegRNA by refining PBS and RT parameters, increasing pegRNA stability and expression levels, and developing automated pegRNA design software. Additionally, efforts are being made to optimize the prime editing system proteins, such as screening for Cas9 and reverse transcriptase variants and performing codon optimization. The final aspect is the regulation of endogenous factors, including the inhibition of mismatch repair mechanisms and the modulation of chromatin environment. These approaches significantly enhance the practicality of prime editing in research and clinical contexts. In conclusion, prime editing represents a major advancement in the field of gene editing, offering powerful tools and methods for both basic research and clinical applications. This review will introduce the discovery, improvement and applications of prime editors, with a focus on prime editing mediated large DNA fragment manipulations. Hopefully, these insights will serve as valuable references for future research and applications of prime editing technology.

Objective:To understand the current situation of the quality of life of medical staff in the context of responding to public health emergencies and discuss its influencing factors,so as to scientifically mobilize the enthusiasm and stability of medical staff in response to public health emergencies and promote the new quality productivity of the medical system under public crises. Methods:The convenient sampling and snowball-sampling were used to investigate medical staff with using World Health Organization Quality of Life Brief Scale,the Utrecht Work Engagement Scale and the Practice Environment Scale,and establish decision tree and neural network models to analyze the factors affecting the quality of life of medical staff. Results:Quality of life of medical staff was (62.61±14.99). The practice environment,work engagement,work willingness,educational background had influence on the quality of life of medical staff (P<0.05),and the influence degree was gradually reduced by the results of the neural network model. Conclusion:The quality of life of medical staff is not high. The practice environment,the work engagement,work willingness is the main influencing factor. Two models have their advantages and disadvantages,which combined use makes the results more meaningful.

Platelets are reprogrammed by cancer via a process called education, which favors cancer development. The transcriptional profile of tumor-educated platelets (TEPs) is skewed and therefore practicable for cancer detection. This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n = 3; Netherlands, n = 5; Poland, n = 1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, and early-stage ovarian cancer. However, these observations warrant prospective validations in a larger population before clinical utilities.

Objective: To understand the current status of diagnosis and treatment of chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL) among hematologists, oncologists, and lymphoma physicians from hospitals of different levels in China. Methods: This multicenter questionnaire survey was conducted from March 2021 to July 2021 and included 1,000 eligible physicians. A combination of face-to-face interviews and online questionnaire surveys was used. A standardized questionnaire regarding the composition of patients treated for CLL/SLL, disease diagnosis and prognosis evaluation, concomitant diseases, organ function evaluation, treatment selection, and Bruton tyrosine kinase (BTK) inhibitor was used. Results: ①The interviewed physicians stated that the proportion of male patients treated for CLL/SLL is higher than that of females, and the age is mainly concentrated in 61-70 years old. ②Most of the interviewed physicians conducted tests, such as bone marrow biopsies and immunohistochemistry, for patient diagnosis, in addition to the blood test. ③Only 13.7% of the interviewed physicians fully grasped the initial treatment indications recommended by the existing guidelines. ④In terms of cognition of high-risk prognostic factors, physicians' knowledge of unmutated immunoglobulin heavy-chain variable and 11q- is far inferior to that of TP53 mutation and complex karyotype, which are two high-risk prognostic factors, and only 17.1% of the interviewed physicians fully mastered CLL International Prognostic Index scoring system. ⑤Among the first-line treatment strategy, BTK inhibitors are used for different types of patients, and physicians have formed a certain understanding that BTK inhibitors should be preferentially used in patients with high-risk factors and elderly patients, but the actual use of BTK inhibitors in different types of patients is not high (31.6%-46.0%). ⑥BTK inhibitors at a reduced dose in actual clinical treatment were used by 69.0% of the physicians, and 66.8% of the physicians had interrupted the BTK inhibitor for >12 days in actual clinical treatment. The use of BTK inhibitors is reduced or interrupted mainly because of adverse reactions, such as atrial fibrillation, severe bone marrow suppression, hemorrhage, and pulmonary infection, as well as patients' payment capacity and effective disease progression control. ⑦Some differences were found in the perceptions and behaviors of hematologists and oncologists regarding the prognostic assessment of CLL/SLL, the choice of treatment options, the clinical use of BTK inhibitors, etc. Conclusion: At present, a gap remains between the diagnosis and treatment of CLL/SLL among Chinese physicians compared with the recommendations in the guidelines regarding the diagnostic criteria, treatment indications, prognosis assessment, accompanying disease assessment, treatment strategy selection, and rational BTK inhibitor use, especially the proportion of dose reduction or BTK inhibitor discontinuation due to high adverse events.
