Objective:To evaluate the efficacy of remimazolam-based anesthesia in daytime laparoscopic cholecystectomy.Methods:In this multicenter, non-inferiority, randomized controlled trial, 300 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients of either sex, aged 18-60 yr, with body mass index of 18-28 kg/m 2, who underwent daytime laparoscopic cholecystectomy under general anesthesia with tracheal intubation at Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine, the Fourth Affiliated Hospital of Zhejiang University School of Medicine, Jinhua Hospital Affiliated to Zhejiang University School of Medicine, Hangzhou First People′s Hospital Affiliated to Westlake University School of Medicine, Ningbo No. 2 Hospital, and the Second Affiliated Hospital of Nanchang University from August 2021 to August 2023, were selected and divided into 2 groups ( n=150 each) using a random number table method: remimazolam group (R group) and propofol group (P group). Anesthesia was induced as follows: Sufentanil was intravenously injected at a rate of 0.5 μg/kg, remimazolam was intravenously injected at a rate of 0.3 mg/kg in group R, propofol was intravenously injected at a rate of 2.0-2.5 mg/kg in group P, and cisatracurium besilate was intravenously injected at a rate of 0.2 mg/kg after loss of consciousness in two groups. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintained as follows: Remimazolam was intravenously injected at a rate of 0.5-1.0 mg·kg -1·h -1 in group R, propofol was intravenously injected at a rate of 4-10 mg·kg -1·h -1 in group P, and remifentanil was intravenously infused at a rate of 0.25-2.00 μg·kg -1·min -1, maintaining intraoperative bispectral index value of 40-60. The success rate of sedation was recorded, and non-inferiority tests were conducted. The time to loss of consciousness, emergence time, extubation time, recovery time of orientation, time of stay in post-anesthesia care unit and occurrence of delayed emergence were recorded. Liver function and renal function were measured before operation and within 24 h after operation. The occurrence of abnormal alanine transaminase, abnormal aspartate transaminase, abnormal creatinine and abnormal urea was recorded. The occurrence of adverse reactions during and after operation was recorded. Results:The success rates of sedation were 98.6% and 99.3% in group R and group P, respectively, there was no statistically significant difference in the success rate of sedation between the two groups ( P>0.05), and the difference in the success rates of sedation between the two groups was -0.007 (95% confidence interval-0.0301-0.0161), which met the pre-set non-inferiority criteria(95% confidence interval >-0.055). Compared with group P, the time to loss of consciousness and recovery time of orientation were significantly prolonged, and the incidence of delayed emergence was increased ( P<0.05), and no statistically significant changes were found in the emergence time, extubation time, time of stay in post-anesthesia care unit and severity of postoperative nausea and vomiting in group R ( P>0.05). There was no statistically significant difference in the abnormal rates of alanine transaminase, aspartate transaminase, creatinine and urea before and after operation between the two groups ( P>0.05). Conclusions:The efficacy of remimazolam-based anesthesia in daytime laparoscopic cholecystectomy is not inferior to that of propofol-based anesthesia.

ObjectiveTo investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis， and to establish a predictive model. MethodsA total of 217 patients who were diagnosed with decompensated hepatitis C cirrhosis and were admitted to The Third People’s Hospital of Kunming l from January， 2019 to December， 2022 were enrolled， among whom 63 patients who were readmitted within at least 1 year and had no portal hypertension-related complications were enrolled as recompensation group， and 154 patients without recompensation were enrolled as control group. Related clinical data were collected， and univariate and multivariate analyses were performed for the factors that may affect the occurrence of recompensation. The independent-samples t test was used for comparison of normally distributed measurement data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed measurement data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis， and the receiver operating characteristic （ROC） curve was used to assess the predictive performance of the model. ResultsAmong the 217 patients with decompensated hepatitis C cirrhosis， 63 （29.03%） had recompensation. There were significant differences between the recompensation group and the control group in HIV history （χ²=4.566， P=0.034）， history of partial splenic embolism （χ²=6.687， P=0.014）， Child-Pugh classification （χ²=11.978， P=0.003）， grade of ascites （χ²=14.229， P<0.001）， albumin （t=4.063， P<0.001）， prealbumin （Z=-3.077， P=0.002）， high-density lipoprotein （t=2.854， P=0.011）， high-sensitivity C-reactive protein （Z=-2.447， P=0.014）， prothrombin time （Z=-2.441， P=0.015）， carcinoembryonic antigen （Z=-2.113， P=0.035）， alpha-fetoprotein （AFP） （Z=-2.063， P=0.039）， CA125 （Z=-2.270， P=0.023）， TT3 （Z=-3.304， P<0.001）， TT4 （Z=-2.221， P=0.026）， CD45⁺ （Z=-2.278， P=0.023）， interleukin-5 （Z=-2.845， P=0.004）， tumor necrosis factor-α （Z=-2.176， P=0.030）， and portal vein width （Z=-5.283， P=0.005）. The multivariate analysis showed that history of partial splenic embolism （odds ratio ［OR］=3.064， P=0.049）， HIV history （OR=0.195， P=0.027）， a small amount of ascites （OR=3.390， P=0.017）， AFP （OR=1.003， P=0.004）， and portal vein width （OR=0.600， P<0.001） were independent influencing factors for the occurrence of recompensation in patients with decompensated hepatitis C cirrhosis. The ROC curve analysis showed that HIV history， grade of ascites， history of partial splenic embolism， AFP， portal vein width， and the combined predictive model of these indices had an area under the ROC curve of 0.556， 0.641， 0.560， 0.589， 0.745， and 0.817， respectively. ConclusionFor patients with decompensated hepatitis C cirrhosis， those with a history of partial splenic embolism， a small amount of ascites， and an increase in AFP level are more likely to experience recompensation， while those with a history of HIV and an increase in portal vein width are less likely to experience recompensation.

ObjectiveTo investigate the association between albumin （Alb） and recompensation by comparing recompensation rate between hepatitis B/C virus-related decompensated liver cirrhosis patients with different Alb levels， and to provide guidance for the identification and management of high-risk patients in clinical practice. MethodsRelated clinical data were collected from 734 patients with hepatitis B/C virus-related decompensated liver cirrhosis who attended The Third People’s Hospital of Kunming from January 1， 2016 to December 31， 2022， and they were divided into three groups based on the level of Alb. The linear regression analysis and chi-square test were used for trend tests. The Kaplan-Meier curve was plotted for the cumulative incidence rate of recompensation in the three groups， and the log-rank test was used for comparison between groups. A Cox proportional-hazards regression model analysis was used to investigate the association between Alb and recompensation in patients with hepatitis B/C virus-related decompensated liver cirrhosis. ResultsAmong the 734 patients with hepatitis B/C virus-related decompensated liver cirrhosis， 270 achieved recompensation， with a recompensation rate of 36.8%. All patients had a median Alb level of 29.90 （25.90 — 34.80） g/L on admission， and according to the level of Alb， they were divided into <25.9 g/L group with 177 patients， 25.9 — 34.8 g/L group with 377 patients， and >34.8 g/L group with 180 patients； 36 patients （20.3%） in the <25.9 g/L group， 138 （36.6%） in the 25.9 — 34.8 g/L group， and 96 （53.3%） in the >34.8 g/L group achieved recompensation， and the recompensation rate increased with the increase in Alb level （χ²=41.730， P<0.001）. After adjustment for all confounding factors， compared with the <25.9 g/L group， there was a significant increase in the incidence rate of recompensation in the 25.9 — 34.8 g/L group （hazard ratio ［HR］=1.842， 95% confidence interval ［CI］： 1.274 — 2.663） and the >34.8 g/L group （HR=2.336， 95% CI： 1.575 — 3.463）. The Kaplan-Meier survival analysis showed that there was a significant difference in the cumulative incidence rate of recompensation between the three groups （χ²=41.632， P<0.001）. ConclusionAlb level is an influencing factor for recompensation in patients with hepatitis B/C virus-related decompensated liver cirrhosis， and the recompensation rate increases with the increase in Alb level.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To explore the relationship between lacune of presumed vascular origin and spontaneous HT in elderly patients with AIS.Methods A total of 671 AIS patients hospitalized in our hospital from January 2021 to September 2024 were prospectively recruited.According to the conditions of lacune of presumed vascular origin by the first cranial MRI examination after admis-sion,they were divided into 330 cases with lacune of presumed vascular origin and 341 cases with-out,and based on the re-examination of head CT or MRI during hospitalization,they were also as-signed into a HT group(139 cases)and a non-HT group(532 cases).Multivariate logistic regres-sion analysis was conducted to clarify the correlation between lacune of presumed vascular origin and spontaneous HT in the elderly AIS patients.The incidence of spontaneous HT and the differ-ences in the subtype composition of spontaneous HT were compared between the mild and severe groups of lacune of presumed vascular origin.Results Baseline NIHSS score,atrial fibrillation,white matter lesions,enlarged perivascular spaces,cerebral microbleeds,large-area cerebral infarc-tion,and ratio of lacune of presumed vascular origin were significantly higher in the HT group than the non-HT group[(10(6,13)vs 9(5,12),P=0.000;28.1％vs 18.0％,P=0.009;74.8％vs 56.0％,P=0.000;79.9％vs 57.5％,P=0.000;30.2％vs 16.9％,P=0.000;45.3％vs 13.2％,P=0.000;66.2％vs 44.7％,P=0.000].The incidence of spontaneous HT was significantly high-er in the lacune of presumed vascular origin group than the non-lacune of presumed vascular ori-gin group(27.9％vs 13.8％,P=0.000).Multivariate logistic regression analysis indicated that lacune of presumed vascular origin was an independent risk factor for spontaneous HT after AIS(OR=2.207,95％CI:1.231-3.959).Subtype analysis on spontaneous HT showed that the patients with lacune of presumed vascular origin had the largest proportion among all subtypes than the non-lacune of presumed vascular origin patients.The incidence of spontaneous HT was significantly higher in the severe lacune of presumed vascular origin group than the mild group(38.1％vs 20.9％,P=0.001).HI2 subtype was mainly observed in the severe group with sponta-neous HT,and HI1 subtype was in the mild group with spontaneous HT.Conclusion Lacune of presumed vascular origin is an independent risk factor for spontaneous HT after AIS in elderly patients.The patients with severe lacune of presumed vascular origin are prone to the occurrence and severe spontaneous HT than the mild lacunar patients.

Objective:To evaluate the efficacy of remimazolam-based anesthesia in daytime laparoscopic cholecystectomy.Methods:In this multicenter, non-inferiority, randomized controlled trial, 300 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients of either sex, aged 18-60 yr, with body mass index of 18-28 kg/m 2, who underwent daytime laparoscopic cholecystectomy under general anesthesia with tracheal intubation at Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine, the Fourth Affiliated Hospital of Zhejiang University School of Medicine, Jinhua Hospital Affiliated to Zhejiang University School of Medicine, Hangzhou First People′s Hospital Affiliated to Westlake University School of Medicine, Ningbo No. 2 Hospital, and the Second Affiliated Hospital of Nanchang University from August 2021 to August 2023, were selected and divided into 2 groups ( n=150 each) using a random number table method: remimazolam group (R group) and propofol group (P group).

Conclusions:The efficacy of remimazolam-based anesthesia in daytime laparoscopic cholecystectomy is not inferior to that of propofol-based anesthesia.

Cancer incidence in China has been rising steadily,with a particularly heavy burden from several high-prevalence malignancies.Medical examination for cancer plays a critical role in the early detection of cancer,precancerous lesions,and precursor conditions,thereby facilitating timely diagnosis and intervention.Such examination also addresses the growing demand for person-alized cancer screening services among diverse population groups.The development of evidence-based,context-specific cancer screening guidelines is essential to enhance the standardization,quality,and equity of preventive screening practices across the country,ultimately improving out-comes in early cancer detection and treatment.Guided by the Department of Medical Emergency Response of the National Health Commission,the Guidelines for Medical Examination for Cancer in Health Examination Agency(2025 Edition)were developed under the leadership of the National Cancer Center.A multidisciplinary panel of experts formulated the guidelines in accordance with the principles and methodology of the World Health Organization Handbook for Guideline Deve-lopment.The guidelines provide evidence-based recommendations on key clinical domains:target cancers and populations,overall screening workflow,screening protocols,diagnostic technolo-gies,result interpretation,follow-up procedures,and quality control.The primary objective is to standardize cancer screening practices in health examination agency and strengthen China's ca-pacity for prevention and control of high-burden cancers.

Background and purpose:Diffuse large B-cell lymphoma(DLBCL)is subclassified into germinal center B-cell-like(GCB)and non-GCB subtypes,which differ in prognosis and treatment response.However,current distinction still relies on invasive pathological assays.This study developed radiomics and deep-learning models based on multiparametric magnetic resonance imaging(MRI)to non-invasively differentiate the two subtypes preoperatively,thereby reducing dependence on histopathological examination.Methods:This study retrospectively included patients with pathologically confirmed DLBCL diagnosed at Huashan Hospital,Fudan University,and other institutions between March 2013 and December 2024.Using multiparametric MRI data,we developed DLBCL-subtype classification models that combined 4 radiomics-based machine-learning algorithms:support vector machine(SVM),logistic regression(LR),Gaussian process(GP)and Naive Bayes(NB),with 3 deep-learning architectures[densely-connected convolutional networks 121(DenseNet121),residual network 101(ResNet101)and EfficientNet-b5].Additionally,two radiologists with different experience levels independently classified DLBCL on MRI in a blinded fashion.Model and radiologist performance were quantified using the area under the receiver operating characteristic curve(AUC),accuracy(ACC),and F1-score to evaluate their ability to distinguish GCB from non-GCB subtypes.This study was approved by the Ethics Committee of Huashan Hospital of Fudan University(No.KY2024-663),and all patients signed informed consents.Results:A total of 173 patients were enrolled(55 with GCB subtype and 118 with non-GCB subtype).Radiomics and deep learning methods effectively distinguished DLBCL subtypes.Among these,the GP radiomics model(based on T1-CE+T2-FLAIR+ADC sequences)and DenseNet121 deep learning model(based on T1-CE+T2-FLAIR+ADC sequences)demonstrated optimal performance.Both achieved excellent results on the internal validation set(GP:AUC=0.900,ACC=0.896,F1=0.840;DenseNet121:AUC=0.846,ACC=0.854,F1=0.774)and maintained robustness on the external validation set.Furthermore,the classification efficacy of the optimal AI model surpassed that of experienced radiologists(highest physician AUC=0.678).Conclusion:Radiomics and deep-learning models based on multiparametric MRI features can effectively differentiate GCB from non-GCB subtypes of DLBCL.Among them,GP and DenseNet121 exhibit outstanding performance,especially when integrating multi-sequence feature sets for classifying DLBCL subtypes on complex imaging data.

Objective:To introduce a new technique of precise exposure and preservation of membranous semicircular canal under endoscope, and to evaluate the protective effect of this method on hearing preservation of semicircular canal occlusion.Methods:The study included three patients with unilateral refractory Meniere′s disease, including 1 male and 2 females, with hearing stage 4 in 2 cases and stage 3 in 1 case, the average hearing thresholds were 72.5, 82.5 and 48.8 dBHL, respectively. All of them were treated with triple semicircular canal occlusion under continuous irrigating mode of endoscopic ear surgery (CIM-EES) in RenMin Hospital of WuHan University. The surgical procedure involved the following key steps: the bony walls of the three semicircular canals near the ampullae were gradually thinned to expose the blue line. The endoscope was positioned as close as possible to the operating area to obtain a clear, magnified view. A micro hook needle was used to create a window on the bony semicircular canals. The hook needle progressively removed the bony material while preserving the membranous canals, which were clearly visible during the procedure. The bone dust was removed out of the surgical area by the continuous exchanged insuline without the help of suction that can avoid the damage of the membranous semicircular canals caused by aspiration and the open bony canals were precisely filled with bone wax and covered with bone powder to ensure complete occlusion of the three semicircular canals. Postoperative follow-up included regular assessments of vertigo control and hearing preservation.Results:All the 3 patients obtained complete hearing preservation at 6 months after surgery, and the hearing preservation rate was 100%. The average hearing thresholds at 6 months postoperatively were 66.3, 81.3, and 50.0 dBHL, respectively. Postoperatively, all patients experienced horizontal spontaneous nystagmus toward the healthy side on the day of surgery and the first day after surgery. One patient reported complete disappearance of tinnitus, while the other two patients showed no change in tinnitus severity. Postoperative MRI revealed complete occlusion of the three semicircular canals with normal vestibular imaging. At 6 months postoperatively, none of the patients experienced any vertigo attacks, suggesting effective control of vertigo symptoms.Conclusions:Precise Semicircular canal occlusion under CIM-EES is a promising technique for the treatment of intractable vertigo in patients with refractory Meniere′s disease. This method provides clear visualization of the membranous canals, reducing the risk of inner ear damage and preserving hearing function of the patients.

Systemic mastocytosis (SM) with an associated myelodysplastic/myeloproliferative neoplasm (MDS/MPN) is a rare subtype of myeloid neoplasms. Avapritinib, a potent and selective inhibitor of KIT D816V, is approved for treating advanced systemic mastocytosis (AdvSM). We report a case of a patient with SM and an associated MDS/MPN treated with avapritinib. The patient achieved sustained complete remission (CR) of SM, with persistent molecular negativity for the KIT D816V mutation, but ultimately succumbed to disease progression to chronic myelomonocytic leukemia (CMML). Although avapritinib, a novel targeted therapy, has significantly improved outcomes for SM, the efficacy of treatment for the associated hematologic neoplasm in patients with SM-AHN may be the primary determinant of long-term overall survival and progression-free survival. This report includes a review of relevant literature to provide insights into the clinical diagnosis and management of this rare entity.
