Objective To systematically evaluate the risk factors for postoperative delirium (POD) in patients undergoing pneumonectomy. Methods PubMed, Web of Science, Cochrane Library, CNKI, Wanfang, and VIP databases were searched from the inception to November 7, 2024 for cross-sectional studies, case-control studies, and cohort studies on POD in patients undergoing pneumonectomy. Two researchers independently screened the literature, extracted data, and evaluated the quality of the literature. RevMan 5.4.1 software was used for meta-analysis. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the literature. Results A total of 12 studies were included, with 5 574 patients. The NOS scores of the literature were all≥6 points. Meta-analysis results showed that age (≥60 years) [OR=2.43, 95%CI (2.01, 2.93), P<0.01], American Society of Anesthesiologists (ASA) classification (Ⅳ) [OR=8.74, 95%CI (5.23, 14.61), P<0.01], history of diabetes [OR=12.81, 95%CI (10.45, 15.71), P<0.01], history of cerebrovascular disease [OR=3.00, 95%CI (2.46, 3.67), P<0.01], depression [OR=7.27, 95%CI (5.46, 9.67), P<0.01], squamous cell carcinoma [OR=4.79, 95%CI (1.83, 12.51), P<0.01], malnutrition [OR=5.25, 95%CI (3.35, 8.25), P<0.01], sleep disorders [OR=2.79, 95%CI (2.28, 3.42), P<0.01], and duration of one-lung ventilation during surgery [OR=1.32, 95%CI (1.11, 1.57), P<0.01] were all risk factors for POD, while high body mass index (BMI) [OR=0.96, 95%CI (0.95, 0.97), P<0.01] was a protective factor for POD. Conclusion Age (≥60 years), ASA classification (Ⅳ), history of diabetes, history of cerebrovascular disease, depression, squamous cell carcinoma, malnutrition, sleep disorders, and duration of one-lung ventilation during surgery are independent risk factors for POD, while high BMI is a protective factor.

Objective: To investigate the prevalence of overweight and obesity among children and adolescents in Yangzhou City, and its association with screen behaviors, so as to provide scientific evidence for weight management among students. Methods: In May 2025, an electronic questionnaire survey was conducted among children and adolescents in Yangzhou City. A total of 3 722 participants were selected from grades 4 to 12 in 18 primary and secondary schools (108 classes) by using stratified cluster random sampling. The Chi square test was used to compare the differences in the detection rates of overweight and obesity among children and adolescents with 5 types of screen behaviors (watching TV, playing electronic games, scrolling short videos, screen based learning, electronic socializing) in different time groups each day (never, >0~<2 h, ≥2 h). Multivariate Logistic regression analysis was performed to examine the associations of five types of screen behaviors, presence of electronic devices in the bedroom, and screen use during meals on the weight status of children and adolescents. Results: The prevalence of overweight and obesity among children and adolescents was 37.3%. For all five types of screen behaviors, the differences in the distribution of overweight and obesity detection rates among children and adolescents across the three time spent categories were statistically significant ( χ 2=30.76- 70.78 , all P <0.01). After adjusting for confounding factors, multivariate Logistic regression analysis revealed that frequent or always using screens during meals( OR =1.63, 95％ CI =1.14~2.31), playing video games ( OR =1.28, 95% CI =1.11-1.48), browsing short videos ( OR =1.29, 95％ CI=1.09-1.54), and screen based learning ( OR =1.26, 95％ CI =1.10-1.44) were significantly associated with overweight and obesity among children and adolescents (all P <0.05). Conclusions Excessive screen use is positively correlated with the incidence of overweight and obesity in children and adolescents. Targeted interventions on screen behaviors among children and adolescents are therefore warranted.

This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective To explore the influence of the medical and health management model based on artificial intelligence (AI) on type 2 diabetes mellitus (T2DM) combined with masked hypertension (MH). Methods A total of 342 patients with T2DM admitted to the hospital from May 2021 to August 2024 were selected as research subjects, and the incidence rate of MH was counted. All patients were classified into the reference group (routine management) and the study group (AI+medical health management) according to the random number table method, with 171 cases in each group. The self-management, glycolipid metabolism and ambulatory blood pressure were compared between both groups before and after intervention. Results Among the 342 patients with T2DM, MH occurred in 34 cases, with an incidence rate of 9.94% (34/342). The self-management ability in the two groups was improved after 6 months and 12 months of intervention, and the self-management ability was higher in the study group (P<0.05). After 6 months and 12 months of intervention, the glucolipid metabolism indexes in both groups were optimized, and the improvements in the study group were greater (P<0.05). The daytime average systolic blood pressure and diastolic blood pressure, 24 h average systolic blood pressure and diastolic blood pressure were decreased in both groups after 6 months and 12 months of intervention, and the study group showed lower indexes (P<0.05). Conclusion T2DM are prone to MH. AI medical and health chronic disease management can enhance patients' self-management ability, help improve glucose and lipid metabolism, lower blood pressure, and help reduce the risk of MH.

With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

ObjectiveTo establish an objective evaluation system based on the quality characteristics of Gardeniae Fructus without relying on the origin label according to the theory of excellent shape， high quality， and superior effect of authentic medicinal materials， thus providing a scientific basis for the standardization of Gardeniae Fructus. MethodsDifferent batches of Gardeniae Fructus samples were collected from different producing areas. Through herbal textual research and a review of modern literature， fruit length， maximum fruit diameter， and chroma were selected as quantitative indicators to characterize the traditional appearance traits of Gardeniae Fructus. The above indicators were measured by a vernier caliper and a spectrophotometer. Through classical famous prescription data and literature analysis， total iridoid glycosides， total crocus glycosides， and total flavonoids were selected as the core component indicators related to efficacy， and their content was determined. Finally， through cluster analysis， the threshold ranges of the quantitative indicators of excellent shape and high quality were determined， and the applicability of the established evaluation system was verified by the determination of the indicators for each batch of medicinal materials. ResultsThe excellent shape indicators of Gardeniae Fructus were the fruit length-to-maximum fruit diameter ratio ≤1.86， 0°≤h≤45°， and L^*≥ 37.32. The content of total iridoid glycosides， total crocus glycosides， and total flavonoids should be no less than 2.2%， 0.44%， and 0.028%， respectively. The measurement results of different batches of Gardeniae Fructus showed that the evaluation system could effectively distinguish the Gardeniae Fructus samples in line with the traditional cognition of excellent shape and high quality. ConclusionThis study preliminarily constructs an excellent shape and high quality-based quality evaluation system for Gardeniae Fructus， which links appearance traits with chemical indicators and provides a methodological basis for the quality control and scientific grading of this herbal medicine.

Objective:To investigate the change trend of hepatectomy for hepatocellular carcinoma and efficacy of fluorescent laparoscopic hepatectomy in a single center from 2014?2023.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 17 232 patients of hepatocellular carcinoma who were admitted to Zhongshan Hospital of Fudan University from January 2014 to December 2023 were collected. There were 14 404 males and 2 828 females, aged 58(range, 11?94)years. Observation indicators: (1) change trend of hepatectomy for hepatocellular carcinoma and application of fluorescent laparoscopy in 2014?2023; (2) propensity score matching between patients undergoing fluorescent and conventional laparoscopic hepatectomy; (3) intraoperative and postoperative conditions of patients in the fluorescent laparoscopy group and the conventional laparoscopy group after propensity score matching. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the nonparametic rank sum test. Propensity score matching was performed using the 1∶3 nearest neighbor matching method, with the caliper value of 0.01. Results:(1) Change trend of hepatectomy for hepatocellular carcinoma and application of fluorescent laparoscopy in 2014-2023. Among 17 232 patients of hepatocellular carcinoma, 4 074 cases underwent laparoscopic surgery, and 13 158 cases underwent open surgery or conversion from laparoscopic to open surgery. From 2014 to 2023, the proportions of laparos-copic surgery in hepatectomy were 8.993%(117/1 301), 6.804%(99/1 455), 9.379%(145/1 546), 17.511%(287/1 639), 23.828%(427/1 792), 24.572%(459/1 868), 29.662%(544/1 834), 31.568%(584/1 850), 38.080%(599/1 573), and 34.246%(813/2 374), respectively. The proportions of Grade Ⅲ surgery in laparoscopic hepatectomy were 11.966%(14/117), 7.071%(7/99), 12.414%(18/145), 21.254%(61/287), 28.337%(121/427), 27.887%(128/459), 34.375%(187/544), 34.644%(214/584), 35.726%(214/599), and 42.681%(347/813), respectively. From 2016 to 2023, the proportions of the application of fluorescent laparoscopy in laparoscopic hepatectomy were 2.069%(3/145), 5.923%(17/287), 8.431%(36/427), 10.022%(46/459), 17.647%(96/544), 24.829%(145/584), 9.182%(55/599), and 12.915%(105/813), respectively. (2) Propensity score matching between patients undergoing fluorescent and conventional laparoscopic hepatectomy. Among the 4 074 patients who underwent laparoscopic liver resection, 503 cases using fluorescent laparoscopy were assigned to the fluorescent laparoscopy group, 3 571 cases using conventional laparoscopy were assigned to the conventional laparoscopy group. A total of 1 794 patients were successfully matched, with 483 cases in the fluorescent laparoscopy group and 1 311 cases in the conventional laparoscopy group. After propensity score matching, the confounding biases of the maximum tumor diameter and the year of surgery were eliminated, and the two groups were comparable. (3) Intraoperative and postoperative conditions of patients in the fluorescent laparoscopy group and the conventional laparoscopy group after propensity score matching. After propensity score matching, there was no perioperative death in either the fluorescent laparoscopy group or the conventional laparoscopy group.The operation time of patients in the fluorescent laparoscopy group was 240(150,328)minutes, the portal triad clamping time was 30(15,45)minutes, the volume of intraoperative blood loss was 50(30,100)mL, the number of patients with complication 72, respectively. For patients in the conventional laparoscopy group, the above indicators were 180(131,240)minutes, 23(15,30)minutes, 55(50,100)mL, and 248, respectively. There were significant differences in the above indicators between the two groups ( Z=?7.593, ?7.372, ?4.941, χ2=3.873, P<0.05). Conclusion:The proportion and difficulty level of laparoscopic hepatectomy for hepatocellular carcinoma in Zhongshan Hospital of Fudan University have shown an upward trend during 2014?2023. Compared with conventional laparoscopy, patients undergoing fluorescent laparoscopic hepatectomy have longer operation time and portal triad clamping time, but less intraoperative blood loss and lower iproportion of complications.

Depression is primarily characterized by persistent low mood,emotional disorders,and loss of interest.Somatization disorder is a type of neurotic disorder,primarily featuring recurrent,varied,and non-organic physical discomfort symptoms.In traditional Chinese medicine,depression with somatization disorder can be classified under the category of"depression"and"hysteria"according to its clinical symptoms.This article focuses on the dynamic evolution of the functions of the kidney,spleen,and liver,and explains the core pathogenesis of depression with somatization disorder based on the theory of"cold water,damp earth,and stagnant wood"proposed by HUANG Yuanyu.It explores the causes and related manifestations.Symptoms mainly characterized by cramps and convulsions can be attributed to the liver;symptoms primarily characterized by heaviness,distension,and dull pain accompanied by weakness can be attributed to the spleen;symptoms primarily characterized by stiffness,reluctance to move or inability to move,and reluctance to extend outward can be attributed to the kidney.Liver depression and spleen dampness,as well as wood depression and earth congestion,are treated by strengthening the spleen and soothing the liver,drying dampness and calming wind,and the modified Xiaoyao Powder combined with Yueju Pill is recommended.Spleen dampness and kidney coldness,earth failure and water overflow,are treated by tonifying the spleen and kidney,warming water and transforming dampness,and the modified Jingui Shenqi Pill combined with Linggui Zhugan Decoction is recommended.Kidney coldness and liver hyperactivity,water not nourishing wood,are treated by warming the kidney and enriching essence,replenishing water and nourishing wood,and the modified Dihuang Yinzi is recommended.This article explores the corresponding etiology,pathogenesis,treatment methods,and prescriptions for depression with somatization disorder,with the aim of providing new insights for clinical diagnosis and treatment.

Objective:To measure and estimate the radiation dose to breast cone-beam CT (CBCT) -scanned examinees, which can provide a dose reference for the selection of mammography equipment in the clinic.Methods:In this study, using a 400 cm 3 Alderson radiation therapy (ART) breast phantom and thermoluminescent detectors (TLDs), the distribution of absorbed dose, and the average glandular dose (AGD), to the examined breasts caused by a breast CBCT scanner was measured and calculated scanner at 50 and 100 mA tube currents. Results:At 50 and 100 mA tube currents, the range of breast absorbed dose inside the examined breast measured based on the phantom was 2.25-7.97 mGy and 3.88-15.68 mGy, respectively, with breast absorbed dose decreasing from the periphery to the centre of the phantom, and the related AGDs were 4.87 and 9.81 mGy, respectively.Conclusions:The AGDs to the breast of CBCT-scanned examinees measured in this study was higher than in the case of commonly used digital mammography. This will be meaningful to provide the guidance on the rational choice of imaging equipment in future clinical practice.
