ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To evaluate the efficacy of defocus incorporated multiple segments (DIMS) on spherical equivalent (SE) and axial length (AL) in myopic children.Methods:Clinical studies on the progress of DIMS lens intervention in myopia reported in CNKI, Wanfang Data, VIP, China Biomedical Literature Database, PubMed, Embase, Cochrane Library, and Web of Science from the establishment of the database to June 2023 were searched.The experimental group and control group used DIMS lens and single vision lens (SVL) for intervention, respectively.Two researchers independently conducted the literature search, screening and data extraction based on the inclusion and exclusion criteria.Literature quality and risk of bias were evaluated in accordance with the requirements of the Cochrane Manual.Meta-analysis was performed using Revman 5.4 software.Results:A total of 7 clinical studies using DIMS lenses to intervene in the development of myopia were included .Seven studies provided complete SE data for analysis, with sample sizes of 1 164 eyes and 1 140 eyes for the DIMS group and SVL group, respectively.Five studies provided complete AL data for analysis, with sample sizes of 339 eyes and 315 eyes for the DIMS group and SVL group, respectively.There were statistically significant differences in SE and AL between DIMS group and SVL group (SE: WMD=0.40, 95% CI: 0.32-0.47, P<0.001; AL: WMD=-0.14, 95% CI: -0.17--0.11, P<0.001).DIMS lens could effectively delay SE progression and AL growth in myopic patients. Conclusions:DIMS lenses could delay the increase of SE and AL to a certain extent.

The Song,Jin,and Yuan dynasties marked a period of transformation in traditional Chinese medicine for visceral syn-drome differentiation,with the emergence of numerous new ideas and theories.Zhang Yuansu was a key figure in the transition from Han and Tang to Jin and Yuan medicine.His Medication Patterns for Treating Deficiency-Excess and Cold-Heat of Five Viscera embod-ies his thinking on visceral syndrome differentiation.This work breaks away from the pre-Song classification of visceral syndrome differ-entiation based on deficiency and excess,focusing on the specific physiological and pathological patterns of the five zang organs and proposing corresponding treatments for their specific syndromes.Medication Patterns propose the diagnosis and treatment of reproductive system diseases based on the Mingmen,assuming that the Mingmen undertakes some of the functions of the kidneys.This enriched the connotations of visceral syndrome differentiation and provided an important theoretical basis for identifying certain complex pathogenesis.The visceral syndrome differentiation concept in the Medication Patterns has promoted subsequent research on visceral syndrome differentiation,exemplified by works such as Li Dongyuan's"Treatise on the Spleen and Stomach",Zhu Danxi's"Treatise on the Xianghuo"and the"Mingmen Theory".In-depth exploration of the inherent differentiation logic and theoretical framework of the Medication Patterns is of great significance to current research on differentiation standards and norms.

Objective To evaluate the reliability of Vitek 2 AST-N335 card for determining the susceptibility of Acinetobacter bauman-nii(AB)to cefoperazone/sulbactam.Methods A total of 318 non-repeated clinical isolates of AB collected in 2023 were tested for antimicrobial susceptibility to cefoperazone/sulbactam using broth microdilution(BMD),the AST-N335 card,and the Kirby-Bauer(K-B)disk diffusion method.Using BMD as the reference method,the reliability of AST-N335 card was assessed,and the accuracy of K-B disk diffusion method as the confirmatory test was validated.Results Compared with BMD,the susceptibility testing of 318 AB strains to cefoperazone/sulbactam using the AST-N335 card showed categorical agreement(CA)of 87.8％(279/318),very major er-ror(VME)of 6.0％(19/318),major error(ME)of 0％(0/318),and minor error(mE)of 1.9％(6/318),which fall outside of the acceptable error range.In contrast,the K-B method achieved CA of 99.4％(316/318),VME of 0％,ME of 0.3％(1/318),and mE of 0.3％(1/318),all within acceptable limits.Of these,the errors with AST-N335 card occurred within the minimum inhibitory concentration(MIC)range of 8-32 μg/mL.Using BMD as the reference method,further analysis was performed on the 171 AB strains with AST-N335 card MIC values of 8-32 μg/mL for cefoperazone/sulbactam.It was revealed that at MIC of 32 μg/mL,the CA was 0％;at MIC of 16 μg/mL,CA was 5.3％(1/19)and VME rate was 84.2％(16/19),both of which substantially exceeded accepta-ble error ranges.At MIC of 8 μg/mL,the CA was 94.9％(131/138)and VME was 2.2％(3/138),both approaching the acceptable ranges.Conclusion The results obtained with Vitek 2 AST-N335 card in determining for cefoperazone/sulbactam are unreliable when the MIC values fall within the range of 8-32 μg/mL,which leads to an underestimation of the resistance rate to cefoperazone/sulbac-tam.This issue requires urgent attention in both laboratories and clinical practice.The K-B disk diffusion method could serve as a sup-plementary verification approach in routine laboratories.

Objective:To develop and validate the Pain nursing Competency Evaluation Questionnaire for Nursing Students to provide an effective tool for measuring the pain management competency of nursing students in China.Methods:The questionnaire was constructed through literature review, semi-structured interviews, focus group discussions, Delphi expert consultation, and a pre-survey. From September 2023 to January 2024, a convenience sampling method was used to select 250 nursing students from Hangzhou Normal University and Lishui University in Zhejiang Province for the survey. Reliability and validity of the developed questionnaire were tested. A random sample of 30 nursing students was selected for retesting after two weeks.Results:A total of 10 female experts were consulted through correspondence. The Pain Care Competency Evaluation Questionnaire for nursing students consists of 36 items. Through exploratory factor analysis, five common factors were extracted: pain health education, comprehensive pain assessment, pain screening and assessment, analgesic interventions, and analgesic side effects nursing, which together explained 61.695% of the variance. The content validity of the questionnaire was 0.96, and the item-level content validity index ranged from 0.900 to 1.000. The overall Cronbach′s α coefficient was 0.924, and the Cronbach′s α coefficients for the five dimensions ranged from 0.856 to 0.915. The test-retest reliability was 0.831. Conclusions:The Pain Care Competency Evaluation Questionnaire for nursing students developed in this study has good reliability and validity. It can be used as a tool to assess nursing students′ competency in pain care and provides a reference for the design and optimization of pain care courses and clinical practice programs for nursing students in undergraduate institutions.

Objective:To investigate the correlation between oral cleanliness and secondary Pulmonary infection in patients with severe chronic obstructive pulmonary disease (COPD) in mechanical ventilation, and to investigate the predictive effect of oral cleanliness on the risk of secondary pulmonary infection.Methods:Using the cross-sectional survey method, the purposeful sampling method was adopted to select 216 patients with severe COPD who were hospitalized in Hangzhou First People′s Hospital from June 2020 to December 2023 and received mechanical ventilation. The oral cleanliness index and general clinical data of patients at admission were collected using the hospital electronic medical record system. The independent influencing factors of secondary lung infection were analyzed by univariate analysis and multivariate Logisitic regression. The predictive value of oral cleanliness index on secondary lung infection was analyzed by patient operating characteristic (ROC) curve.Results:216 patients with severe COPD who underwent mechanical ventilation were included.Patients aged 37-84 (66.81 ± 8.98) years were included, including 125 males and 91 females.Among them, 89 cases developed secondary pulmonary infection, with an infection rate of 41.20%.Univariate analysis and multivariate Logistic regression analysis showed that, Beck Oral Rating Scale (BOAS) score ( OR = 1.371), visual simulation score of oral odor ( OR = 1.405), gum index ( OR = 3.508), plaque index ( OR = 14.357), smoking history ( OR = 6.772), duration of disease ( OR = 1.391), COPD assessment test score ( OR = 1.269) and mechanical ventilation time ( OR = 1.302) were independent factors for secondary pulmonary infection (all P<0.05). ROC curve analysis showed that oral cleanliness index combined with infection prediction was effective (the area under the ROC curve was 0.833) . Conclusions:Oral cleanliness was closely related to secondary pulmonary infection in patients with severe COPD with mechanical ventilation. BOAS score, visual simulation score of oral odor, gingival index and plaque index could predict secondary pulmonary infection independently, and combined test could predict secondary pulmonary infection.

Objective·To compare the safety and short-term outcomes of robot-assisted versus laparoscopic-assisted proximal gastrectomy combined with double-flap esophagogastrostomy in the treatment of early upper gastric cancer.Methods·A retrospective cohort study was conducted to analyze the clinical and pathological data of 31 early gastric cancer patients who underwent proximal gastrectomy combined with double-flap esophagogastrostomy for gastrointestinal reconstruction at the Department of Gastrointestinal Surgery,Renji Hospital,Shanghai Jiao Tong University School of Medicine,from September 2023 to March 2024.Based on the surgical approach,patients were divided into the robot-assisted surgery group(robotic group,20 cases)and the laparoscope-assisted surgery group(laparoscopic group,11 cases).General clinical data,intraoperative conditions,and postoperative recovery between the two groups were compared.At the 6-month postoperative follow-up,upper gastrointestinal radiography and esophagogastroscopy were performed to assess anastomotic stricture and gastroesophageal reflux disease.Additionally,the gastric cancer-specific module of the European Organization for Research and Treatment of Cancer(EORTC),Quality of Life Questionnaire-Stomach 22(QLQ-STO22),was used to evaluate the patients' quality of life.Results·The general data of the two groups,including gender,age,preoperative comorbidities,American Society of Anesthesiologists(ASA)classification,Siewert classification,and pathological staging of tumors,showed no statistically significant differences(all P>0.05).All patients successfully underwent the procedure without conversion to open surgery.The time for gastroesophageal anastomosis was significantly shorter in the robotic group compared to the laparoscopic group[(31.09±8.23)min vs(43.73±8.83)min,P<0.001],while there were no statistically significant differences in other intraoperative and postoperative parameters,including operative time,intraoperative blood loss,number of lymph nodes removed,duration of gastric tube placement,time to start a liquid diet,length of postoperative hospital stay,and incidence of postoperative complications(all P>0.05).At the 6-month postoperative follow-up,30 patients completed the follow-up,with one patient lost to follow-up in the robotic group.Upper gastrointestinal radiography and esophagogastroscopy results showed that only one patient in the laparoscopic group developed an anastomotic stricture,while one patient in the robotic group developed grade A and one developed grade B gastroesophageal reflux disease(GERD).In addition,one patient in the laparoscopic group also developed grade B GERD.The incidences of GERD and anastomotic stricture showed no statistically significant differences between the two groups(both P>0.05).EORTC QLQ-STO22 results indicated that the robotic group had significantly lower scores in the dimensions of dysphagia,gastroesophageal reflux,and dietary restrictions,as well as in the total score,compared to the laparoscopic group(all P<0.05).Conclusion·Robot-assisted proximal gastrectomy combined with double-flap esophagogastrostomy is safe and feasible.It shortens anastomosis time and offers potential advantages in postoperative functional recovery and quality of life improvement.

Background and purpose:Accurate preoperative differentiation between vagal nerve cervical schwannomas(SCCS)and sympathetic chain cervical schwannomas(SCCS)in the neck is crucial because of their different postoperative complication.This study aimed to construct and validate a Diagnosis Score and vascular displacement nomogram for the preoperative differentiation of VNCS from SCCS in the neck.Methods:This cross-sectional study retrospectively analyzed patients with pathologically confirmed VNCS and SCCS at Fudan University Shanghai Cancer Center from January 2017 to April 2022.This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(approval number:1612167-18).Inclusion criteria:① histopathological diagnosis of VNCS or SCCS through biopsy or surgical resection;② patients with complete clinic data;③availability of preoperative contrast-enhanced computed tomography(CT)or magnetic resonance imaging(MRI)examinations.Patients were excluded for:① contrast agent contraindications;② poor image quality;③ severe artifacts;④ non-standard scanning protocols.The cohort was randomly divided into training and validation sets in a 7∶3 ratio.Two radiologists(one resident and one attending physician)independently evaluated tumor characteristics(location,size and vascular displacement patterns)on preoperative imaging.Independent predictors were selected using LASSO regression analysis to construct a diagnostic scoring system and nomogram,with model performance evaluated by the receiver operating characteristic(ROC)curve.Results:A total of 110 patients were enrolled,with 77 cases allocated to the training set and 33 cases to the validation set.The age range was 24-78 years,and the mean age was(51.22±12.36)years.There were no statistically significant differences in baseline characteristics including age,gender,tumor location and size between the two patient groups(P＞0.05).ICA/ECA splaying was significantly associated with SCCS(P＜0.001),while the ICA/IJV splaying was significantly associated with VNCS(P＜0.001).Lateral and posterior ICA displacement were significantly associated with SCCS(P＜0.001),and medial and anterior ICA displacement were significantly associated with VNCS(P＜0.001).Five features including tumor size,ICA displacement direction,IJV displacement direction,ICA/ECA splaying and ICA/IJV splaying were used to establish the Diagnosis Score and nomogram.The nomogram combined imaging features showed favorable preference value for differentiating VNCS from SCCS,with area under curve(AUC)values of 0.953(95%CI:0.912-0.994)and 0.939(95%CI:0.885-0.993)for the training and validation cohorts,respectively.Conclusion:The Diagnosis Score and vascular displacement nomogram showed favorable predictive efficacy for differentiating VNCS from SCCS in the neck,and might be useful for clinical decision-making.

Conclusions:DIMS lenses could delay the increase of SE and AL to a certain extent.

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.
