OBJECTIVE: To explore the characteristics and rules of the locations of acupoints selected in weight loss after syndrome differentiation of acupuncture and moxibustion, and provide quantitative evidence for the location specificity of acupoint selection in weight loss. METHODS: Clinical research articles on acupoint selection based on syndrome differentiation of acupuncture and moxibustion in weight loss were retrieved in China National Knowledge Infrastructure (CNKI), from the inception to September 20th, 2024, and the data about acupoints and differentiated syndromes were extracted. Based on graph theory, the acupoint-syndrome network was established and its topological parameters such as node degree, value of betweenness centrality, description length and number of community were calculated. RESULTS: ①The description length of the limbs was 4 255.592, and that of the trunk was 3 274.312. The information contained in the acupoint-syndrome network for the acupoints on the limbs was greater than that for those on the trunk. ②The value of betweenness centrality and node degree showed a nonlinear relationship, with R²of 0.812 1 for the trunk and 0.321 8 for the limbs. The values of betweenness centrality for the acupoints on the trunk were uniformly distributed, and the difference among these values was much smaller than that for the acupoints on the limbs. It suggested that the distance from each trunk acupoint to network center was similar, and the importance among these acupoints to network was similar, while the importance among acupoints located on the limbs was different significantly. ③The frequency proportion of acupoints on the trunk showed uniform distribution among different syndromes, while that of some acupoints located on the limbs such as Taichong (LR3), Neiting (ST44) and Taixi (KI3) presented a correlation with the syndromes. CONCLUSION In weight loss with acupuncture and moxibustion, the correlation between the limb acupoints and syndromes is more diverse and specific than that between the trunk acupoints and syndromes. The differences in acupoint selection for simple obesity treated with acupuncture and moxibustion are mostly reflected in the acupoints on the four limbs rather than those on the trunk. It provides an approach to acupoint selection for "local weight loss" and "general regulation" in treatment with acupuncture and moxibustion.

Objective To investigate the internalized weight bias and weight control beliefs regarding the current status,influencing factors,and impacts on eating behaviors of women losing weight. Methods A convenient sampling method was used to select the females who underwent physical examination in the Peking Union Medical College Hospital from August to December 2023.The general information questionnaire,Weight Bias Internalization Scale,Weight Control Belief Questionnaire,and Chinese version of Three-Factor Eating Questionnaire were utilized for investigation.Latent class analysis was conducted to explore the potential categories based on the characteristics of internalized weight bias and weight control beliefs.Univariate analysis and multiple-factor linear regression analysis were performed to explore influencing factors of potential categories and their effects on eating behaviors. Results A total of 518 subjects were included in this study.The internalized weight bias and weight control beliefs could be classified into three potential categories: low weight bias tolerance type(53.7%),medium weight bias persistence type(29.5%),and high weight bias overcritical type(16.8%).Logistic regression analysis showed that body mass index,unmarriage,and divorce were the influencing factors of the high weight bias overcritical type.The scores of non-control eating and emotional eating in medium weight bias persistence type and high weight bias overcritical type were higher than those in low weight bias tolerance type(all P<0.001). Conclusions The attitudes of Chinese women towards body weight can be categorized into low weight bias tolerance type,medium weight bias persistence type,and high weight bias overcritical type.The high weight bias overcritical type is characterized by high weight bias and high personal responsibility attribution,and it is closely associated with negative eating behaviors.A high body mass index,unmarriage,and divorce are high-risk factors for developing the high weight bias overcritical type.

Bariatric and metabolic surgery has become a primary treatment for decompensated obesity, with the number of procedures rapidly increasing in China in recent years. Various improved and novel surgical techniques have emerged. Given the characteristics of the Chinese obese population lower body mass index compared to Western populations and frequent pancreatic islet dysfunction laparoscopic Roux-en-Y gastric bypass remains one of the mainstream procedures in China. Although the Procedural Guideline for Laparoscopic Roux-en-Y Gastric Bypass (2019 Edition) has provided standardized surgical steps, mastering and routinely implementing the procedure in clinical practice continues to pose significant challenges. Compared to laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass is more technically demanding and requires a longer learning curve. To avoid suboptimal weight loss or severe postoperative complications resulting from non-standardized techniques, this article summarizes the authors' clinical experience, emphasizing key technical steps: creation of the gastric pouch, standardization of gastrojejunal and jejunojejunal anastomoses, hiatal closure, and full serosalization. These insights aim to improve procedural safety and therapeutic efficacy by offering a set of practical process optimization strategies.

With the increasing number of obese patients worldwide, metabolic and bariatric surgery (MBS) has quickly become an effective way to treat obesity and related metabolic diseases such as type 2 diabetes, hypertension, lipid abnormalities, etc. Although MBS has become an important part of general surgery, there is still controversy regarding the indications for MBS. In 1991, the National Institutes of Health (NIH) issued a statement on the surgical treatment of severe obesity and other related issues, which continues to be the standard for insurance companies, health care systems, and hospital selection of patients. The standard no longer reflects the best practice data and lacks relevance to today's modern surgeries and patient populations. After 31 years, in October 2022, the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO), the world's leading authorities on weight loss and metabolic surgery, jointly released new guidelines for MBS indications, based on increasing awareness of obesity and its comorbidities and the accumulation of evidence of obesity metabolic diseases. In a series of recommendations, the eligibility of patients for bariatric surgery has been expanded. Specific key updates include the following: (1) MBS is recommended for individuals with BMI≥35 kg/m², regardless of the presence, absence, or severity of co-morbidities; (2) MBS should be considered for individuals with metabolic diseases and BMI 30.0-34.9 kg/m²; (3) the BMI threshold should be adjusted for the Asian population:: BMI≥25 kg/m² suggest clinical obesity, and BMI ≥ 27.5 kg/m² population should consider MBS; (4) Appropriately selected children and adolescents should be considered for MBS.

Obesity is a global public health problem that imposes a heavy economic burden on society. The current main strategies for treating obesity include lifestyle interventions, pharmacological treatments, endoscopic treatments and metabolic surgery. With the development of medical technology, weight reduction by intragastric occupancy devices represented by intragastric balloons and intragastric capsules are gradually emerging. Intragastric balloons are used to reduce weight by occupying the volume of the stomach with balloons filled with different volumes of gas or liquid, among which ReShape, Orbera, Obalon, Elipse and Spatz balloons are gradually used in patients with mild to moderate obesity due to their non-invasive, high safety and reusable advantages. Intragastric capsules are recommended in overweight and obese patients for weight loss through hydrogels with transient superabsorbent swelling properties and completely noninvasive. Both approaches achieve weight loss by limiting gastric volume, increasing satiety and reducing food intake. Despite the presence of adverse gastrointestinal events associated with nausea, vomiting, and abdominal distention, they offer new ideas for the non-invasive clinical treatment of obesity.

OBJECTIVE: To investigate the effectiveness of osteotomy of non-core weight-bearing area of the lateral tibial plateau, reduction, and internal fixation in the treatment of tibial plateau fractures involving posterolateral column collapse. METHODS: A clinical data of 23 patients with tibial plateau fractures involving posterolateral column collapse, who had undergone osteotomy of non-core weight-bearing area of the lateral tibial plateau, reduction, and internal fixation between January 2015 and June 2021, was retrospectively analyzed. There were 14 males and 9 females with an average age of 42.6 years ranging from 26 to 62 years. The causes of injury included traffic accident in 16 cases, falling from height in 5 cases, and other injuries in 2 cases. According to Schatzker classification, there were 15 cases of type Ⅴ and 8 cases of type Ⅵ. The time from injury to operation was 4-8 days with an average of 5.9 days. The operation time, intraoperative blood loss, fracture healing time, and complications were recorded. The depth of articular surface collapse of posterolateral column and posterior inclination angle (PSA) of the tibial plateau were compared before operation and at 2 days and 6 months after operation; fracture reduction of tibial plateau fracture was evaluated by Rasmussen anatomic score. The recovery of knee function was evaluated by Hospital for Special Surgery (HSS) score at 2 days and 6 months after operation. RESULTS: All 23 patients were completed the operation successfully. The operation time was 120-195 minutes, with an average of 152.8 minutes; the intraoperative blood loss was 50-175 mL, with an average of 109.5 mL. All patients were followed up 12-24 months, with an average of 16.7 months. One patient had superficial wound infection after operation, and the incision healed after dressing change; primary healing of incision of other patients was obtained. The fracture healing time was 12-18 weeks, with an average of 13.7 weeks. No failure of internal fixation, varus and valgus deformity of the knee joint, and instability of the knee joint was found at last follow-up. One patient developed joint stiffness and the range of motion of the knee joint was 10°-100°; the range of motion of the knee joint of other patients was 0°-125°. At 2 days and 6 months after operation, the depth of articular surface collapse of posterolateral column, PSA, and Rasmussen anatomic scores significantly improved when compared with those before operation ( P<0.05). There was no significant difference between the two postoperative time points ( P>0.05). The HSS score at 6 months after operation was significantly higher than that at 2 days after operation ( P<0.05). CONCLUSION For tibial plateau fractures involving posterolateral column collapse, reduction and internal fixation through osteotomy of non-core weight-bearing area of the lateral tibial plateau has the advantages of fully expose the posterolateral column fragment, good articular surface reduction, sufficient bone grafting, and fewer postoperative complications. It is beneficial to restore knee joint function and can be widely used in clinic.

Introduction: The demanding nature of medical school causes students to experience stress, anxiety, and depressive episodes that may cause students to gain or lose weight. This study aimed to determine the association of weight changes and stress levels among a private medical school students. Methods: Data were collected two times with an interval of 30 days through on-site measurement of the students’ anthropometrics using a stadiometer and utilization of online survey questionnaires accessed via QR code. Demographics and disease states were identified in the first round of data collection while the Perceived Stress Scale-10 (PSS-10) and identification of stressors was integrated in the second round of data collection. Results: Among the 212 individuals, 69.8% were categorized into having perceived moderate stress levels, 22.2% with high stress, and 8% with low stress. Of the 212 cases, 86 gained weight, 91 lost weight, and 35 had no change in weight. Fear of failure, poor motivation, and difficulty understanding lectures are among the top overall stressors. The study noted that there is a moderate association between stress and weight changes but it is not enough to reach statistical significance (0.161), as the sample size was not reached. The study revealed that the prevailing diseases were Polycystic Ovarian Syndrome, Hypothyroidism, and Hypertension, which have varying degrees of impact on weight change. Conclusion There is an association between weight changes and stress levels among first to fourth year medical students of a private medical school from A.Y. 2023-2024.

OBJECTIVES: To compare the effect of different frequency of acupoint thread-embedding on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention. METHODS: A total of 126 subjects with overweight/obesity of spleen deficiency and dampness retention were randomized into a 2-week group(63 cases, 13 cases dropped out)and a 3-week group(63 cases, 11 cases dropped out, 1 case was eliminated). The two groups were treated with acupoint thread-embedding once every 2 weeks and once every 3 weeks respectively, Zhongwan(CV 12), Shuifen(CV 9), Qihai(CV 6), Guanyuan(CV 4) and bilateral Zhangmen(LR 13), Tianshu(ST 25), Liangmen(ST 21), Daheng(SP 15), Fujie(SP 14), Pishu(BL 20), Yinlingquan(SP 9)were selected. Four times were required in the two groups. Before and after treatment, follow-up after 2 months of treatment completion, the body mass index(BMI), body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, fat percentage(F%), skin fold thickness were observed in the two groups. RESULTS: After treatment and in follow-up, the BMI, body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, F%, skin fold thickness in the two groups were decreased compared with those before treatment (P<0.001, P<0.01), the changes of BMI, body weight, obesity degree, F%, skin fold thickness in the 2-week group were larger than those in the 3-week group(P<0.05, P<0.01, P<0.001). CONCLUSIONS The effect of acupoint thread-embedding once every 2 weeks on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention is superior to that once every 3 weeks.

OBJECTIVE: To investigate the effect of acute graft-versus-host disease (aGVHD) mouse models established respectively by total body irradiation (TBI) and busulfan combined with cyclophosphamide (BU/CY) conditioning regimens after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: Bone marrow cells and splenic mononuclear cells were isolated respectively from femur, tibia, and spleen of C57BL/6 male mice (H-2Kb) which were selected as donors. After TBI pretreatment, BALB/c female mice (H-2Kd) were injected with donor bone marrow cells 1×10⁷/50 μl and splenic mononuclear cells 2×10⁷/100 μl through caudal vein, while CB6F1 female mice (H-2Kd/b) with donor bone marrow cells 2×10⁷/100 μl and splenic mononuclear cells 1×10⁸/500 μl after BU/CY pretreatment. The successful establishment of the aGVHD models were determined by post-transplant manifestations, rate of chimerism, target organ damage, etc. Results: After transplantation, mice of both groups showed listlessness, low activity, continued weight loss, and typical manifestations of aGVHD such as alopecia, hunched posture, diarrhea, and anal swelling. and died within 4 weeks. Flow cytometry detection showed complete chimerism in all the mice. Pathological examination of skin, intestines, liver, lung, and spleen tissues showed obvious aGVHD pathological changes. However, the weight loss, ruffled fur, and alopecia combined with severe scurf on those hair-free areas were significantly apparent in TBI group than BU/CY group, as well as higher aGVHD score, and the differences were statistically significant (P<0.05). CONCLUSION Both TBI and BU/CY as conditioning regimens can successfully establish stable mouse models of aGVHD after fully allo-HSCT and haploidentical HSCT for further research about mechanism of aGVHD. BU/CY conditioning regimen can more truly simulate physiological status in vivo of patients with chemotherapy based conditioning regimen, while TBI conditioning regimen shows significantly more typical aGVHD symptoms and easier to operate.

With the increasing prevalence of obesity and the popularity of bariatric surgery, more and more patients with obesity are undergoing bariatric surgery. "Precision Medicine" is a new generation of medical concepts. We introduce the concept of "precision medicine" into precision bariatric and metabolic surgery, in order to optimize and integrate modern surgical theory and technology with traditional surgical methods under the requirements of high precision and high efficiency standards, so as to achieve minimal trauma and invasion, maximal organ protection, minimal medical cost and best weight loss effect. Chinese Society for Metabolic and Bariatric Surgery (CSMBS) organized some domestic bariatric surgery experts to conduct four relevant problem-oriented and 36 clinically practical problems, including precise preoperative assessment, precise perioperative management, precise surgical operation, and precise postoperative management. Based on domestic and foreign literature evidence and combined with Chinese conditions and clinical experience, CSMBS has formulated a Chinese expert consensus on precision obesity metabolic surgery, aiming to provide guidance for the clinical practice of precision obesity metabolic surgery in our country.
