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.

Objective:To evaluate the safety and effectiveness of rubber band-assisted endoscopic submucosal excavation (RB-ESE) for gastric submucosal tumors (SMT).Methods:A retrospective study was conducted on data of gastric SMT patients who underwent ESE in Affiliated Hospital of Yangzhou University from January 2017 to August 2022. A total of 48 patients were selected and divided into two groups: RB-ESE group ( n=20) and the conventional ESE (C-ESE) group ( n=28). The operation time, bleeding rate and perforation rate during operation, the retention rate of the mucosal cap, the number of clips, postoperative complications, and the hospitalization time were analyzed. Additionally, correlations between complications and tumor size/location and between bleeding and perforation were evaluated. Results:No significant difference was found in the general conditions between the two groups ( P>0.05). The operation time of RB-ESE group (14.82±2.31 min) was significantly shorter than that of C-ESE group (23.70±3.67 min) ( t=-9.539, P<0.001). The intraoperative bleeding rates were 20.0% (4/20) and 42.9% (12/28) in the RB-ESE group and C-ESE group respectively ( χ2=2.743, P=0.098), while the intraoperative perforation rates were 25.0% (5/20) and 46.4% (13/28) respectively ( χ2=2.286, P=0.131). Furthermore, the mucosal cap preservation rate was notably higher in the RB-ESE group at 60.0% (12/20) compared with 7.1% (2/28) in the C-ESE group ( χ2=15.777, P<0.001). The number of clips applied to close the wound was 8.05±1.40 and 10.43±1.96 in the RB-ESE group and C-ESE group respectively ( t=4.925, P<0.001). The postoperative hospital stays were 4.35±0.75 days and 5.00±0.86 days respectively in two groups ( t=2.724, P=0.009). No postoperative bleeding or perforation occurred in either group. The results showed that the occurrence of perforation and bleeding were associated with tumor diameter. Patients with tumor size ≥2 cm showed increased proportions of intraoperative bleeding [68.4% (13/19), P<0.001] and perforation [78.9% (15/19), P<0.001]. There was a correlation between intraoperative bleeding and perforation ( P<0.001). Conclusion:RB-ESE proves to be an effective and safe approach for managing gastric SMT, offering advantages such as reduced operation time and hospital stays, improved retention of the mucosal cap post-operation, and less clips use. The results suggest that RB-ESE could be widely adopted for treating SMT.

Objective To study the therapeutic effect of Chaiqi Yigan granules on H22 liver cancer-bearing mice and its effect on intestinal flora.Methods The mouse model of liver cancer was constructed by subcutaneous inoculation of H22 cell suspension.The rats were divided into normal group,model group(H22 liver cancer-bearing model),positive control group(50 mg·kg-1 Sorafenib)and experimental-L,-H groups(12.42,49.68 g·kg-1 Chaiqi Yigan granules).Stripping the tumor,weighing the tumor.The serum marker alpha-fetal protein(AFP)of liver cancer was detected by enzyme-linked immunosorbent assay(ELISA)method.The intestinal flora was detected by 16 s rRNA.The expression of tight junction proteins Occludin and zonula occludens protein-1(ZO-1)in colonic mucosa and the changes of intestinal mucosal permeability were observed by immunohistochemical staining.Results The tumor weights in model group,experimental-L group,experimental-H group and positive control group were(1.18±0.08),(1.13±0.10),(0.84±0.13)and(0.55±0.07)g;the expression of AFP were(7.93±0.21),(7.74±0.23),(7.25±0.53)and(5.59±0.03)ng·mL-1,respectively.There were significant differences in the above indexes between the experimental-H group and the model group(P＜0.01).The Bacteroidota in normal group,model group,experimental-L group,experimental-H group and positive control group were(32.10±8.67)％,(12.72±4.31)％,(50.34±13.48)％,(28.37±6.17)％and(44.47±2.85)％;Firmicutes were(67.18±4.20)％,(82.47±4.64)％,(38.16±12.88)％,(68.39±5.83)％and(52.61±2.86)％;Lactobacillaceae were(12.20±3.25)％,(1.85±0.63)％,(9.17±2.47)％,(3.56±0.74)％and(27.83±6.77)％,respectively.There were significant differences in the above indexes between the experimental-H group and the model group(P＜0.01,P＜0.05).The results of colonic immunohistochemistry showed that the cells in the model group were loosely arranged,the intercellular proteins were reduced,and the intercellular space was increased,resulting in increased mucosal permeability.With the increase of the dose of Chaiqi Yigan granules,Occludin protein and ZO-1 protein gradually increased,making the cells arranged neatly and orderly,the intercellular space became smaller,and the permeability of the mucosa gradually returned to normal.Conclusion Chaiqi Yigan granules may play an anti-hepatocellular carcinoma role by improving intestinal mucosal permeability and regulating intestinal flora.

Objective: To understand the changes in pain and its effects in patients with the diagnosis of herpes zoster. Methods: A total of 3 487 patients diagnosed with herpes zoster (HZ) for the first time at the outpatient department of Miyun District Hospital from January 1, 2017, to December 31, 2019, were included in the study. The information of patients was registered and issued with a record card. Patients were required to record the time of pain and rash by themselves. Telephone follow-up was conducted at 21, 90, 180 and 365 days after the onset of rashes, including hospitalization, location of rash and pain, and the time of start and end. The impact of pain on life was evaluated by the Zoster Brief Pain Inventory (ZBPI). Results: The age of 2 999 HZ patients included in the analysis were (53±16) years old, including 1 377 (45.91%) males and 1 903 (63.45%) patients aged 50 years and older. After 21 days of rash, mild, moderate and severe pain accounted for 20.87% (626 cases), 37.98% (1 139 cases) and 33.81% (1 014 cases), respectively. Only 5.07% (152 cases) had no pain or discomfort, and 2.27% (68 cases) had no pain but discomfort. Most of the pain sites were consistent with the rash sites. The chest and back and waist and abdomen were the most common, accounting for 35.58% (1 067 cases) and 29.18% (875 cases), respectively, followed by the limbs and face and neck, accounting for 16.74% (502 cases) and 16.40% (492 cases), respectively. The M (Q₁, Q₃) of pain days in the HZ patients was 14 (8, 20) days, and the incidence of post-herpetic neuralgia (PHN) was 6.63% (171/2 580) (excluding 419 patients who refused to visit or lost to visit on 90 days after the onset of rash). The pain score of HZ patients within 21 days after the rash was (5.19±2.73) points, and the pain score of PHN patients was (7.61±2.13) points, which was significantly higher than that of non-PHN patients [(5.04±2.69) points] (P<0.001). Daily activities, emotions, walking ability, work, social interaction, sleep and recreation were affected for 21 days after the rash in HZ patients, ranging from 60.79% to 83.83%, with sleep being the most affected (83.83%). The impact scores of pain and life dimensions in PHN patients ranged from 4.59 to 7.61 points on the ZBPI scale, which were higher than those in non-PHN patients (2.49-5.04) (t values ranged from 8.86 to 11.67, all P values <0.001). Conclusion: The proportion of pain in HZ patients after the diagnosis is high, and the pain is more obvious in patients with PHN and HZ patients aged 50 and older, which has a greater impact on their daily lives.

Cystine/glutamate antiporter [system Xc(-)] is a sodium independent amino acid transporter, which is a heterodimer composed of light chain subunit xCT and heavy chain subunit 4F2hc (CD98) through covalent disulfide bond. System Xc(-) typically mediates cystine uptake and glutamate output, helps to maintain the balance of glutamate, cystine and cysteine inside and outside the cell, regulates the level of glutamate inside and outside the membrane and the synthesis of intracellular glutathione, thus affecting oxidative stress and glutamate neurotoxicity. This review expounds the structure and function of system Xc(-), analyzes the role of the transporter in physiology and pathology, discusses the role and mechanism in different diseases, and discusses the specific research progress of system Xc(-) as a drug target. This review summarizes the research status of system Xc(-) and provides theoretical guidance for further research on system Xc(-) and drug discovery.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.
