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 explore the long-term effect of Zhenzhu Tiaozhi capsule（FTZ） on hemoglobin A1c（HbA1c）in patients with type 2 diabetes mellitus （T2DM） based on real-world data. Method:T2DM patients who were provided with FTZ （FTZ group） and those receiving conventional hypoglycemic drugs （control group） were extracted from the hospital information system （HIS） of the First Affiliated Hospital of Guangdong Pharmaceutical University， followed by propensity score matching （PSM） for balancing the confounding factors between groups. With HbA1c as the efficacy evaluation index， the difference in efficacy between the two groups was compared using t-test and χ² test. For repeated measurement data of the same patient， the difference in efficacy and the stability of FTZ against HbA1c were analyzed by generalized estimating equation （GEE）. The factors that might affect the efficacy of FTZ against HbA1c were subjected to multivariate linear regression analysis （MLRA）， and the subgroup analyses were then conducted after the stratification of relevant factors. Result:There were 46 patients included in the FTZ group and 1 208 patients in the control group. PSM yielded 42 pairs of samples with balanced covariates between groups. As revealed by one-year observation， ① HbA1c in the FTZ group after treatment was 6.51%±1.09%. No significant difference was observed either in pre- and post-treatment comparison in the FTZ group or in its comparison with the control group. At the same time， the HbA1c compliance rate in the FTZ group was 73.8% after treatment. No significant difference was observed either in pre- and post-treatment comparison in the FTZ group or in its comparison with the control group. ② The GEE results showed that the post-treatment HbA1c levels in the two groups were not significantly different from each other. Moreover， the HbA1c level remained stable over treatment time. ③ MLRA and subgroup analyses results demonstrated that FTZ was more effective in patients with high baseline HbA1c ［β=-0.530，95% confidence interval（CI） -0.850～-0.209，P<0.01］ or those who were complicated with hypertension （β=-0.918，95%CI -1.614～-0.222，P<0.05）. Conclusion:In the real world， FTZ is able to control the blood sugar， and its effect is similar to those of conventional hypoglycemic drugs. Besides， it is capable of stabilizing the blood sugar for a long time.

AIM:To explore the effects of mammalian target of rapamycin (mTOR) double inhibitor AZD8055 on autophagy and apoptosis of human cholangiocarcinoma cell line HuCCT1. METHODS:The effect of AZD8055 on the viability of HuCCT1 cells was detected by MTT assay. Autophagosome was detected by acridine orange (AO) staining. Af-ter treated with AZD8055, the expression levels of apoptosis-related proteins Bcl-2, Bax and cleaved caspase-3 and auto-phagy marker proteins beclin 1, LC3 and p62 were determined by Western blot. Apoptotic rate was analyzed by flow cyto-metry with Annexin V-FITC/PI double staining. RESULTS:AZD8055 significantly inhibited the viability of HuCCT1 cells (P<0.05). AO staining showed that AZD8055 significantly increased orange granules in the cytoplasm. After treated with AZD8055, compared with the control group, the protein level of beclin 1 and the ratio of LC3-Ⅱ/LC3-Ⅰ were enhanced, while p62 was attenuated (P<0.05). The protein expression level of pro-apoptotic regulator Bax was down-regulated and anti-apoptotic regulator Bcl-2 was increased. The protein level of cleaved caspase-3 was reduced (P<0.05). The results of flow cytometry showed that AZD8055 inhibited cell apoptosis. CONCLUSION:AZD8055 inhibits the viability of cholangiocarcinoma cells, and the mechanism is closely related with autophagy induced by AZD8055.

OBJECTIVETo observe wet cupping therapy (WCT) on local blood perfusion and analgesic effects in patients with nerve-root type cervical spondylosis (NT-CS).

METHODSFifty-seven NT-CS patients were randomly divided into WCT group and Jiaji acupoint-acupuncture (JA) group according a random number table. WCT group (30 cases) was treated with WCT for 10 min, and JA group (27 cases) was treated with acupuncture for 10 min. The treatment efficacies were evaluated with a Visual Analogue Scale (VAS). Blood perfusion at Dazhui (GV 14) and Jianjing (GB 21) acupoints (affected side) was observed with a laser speckle flowmetry, and its variations before and after treatment in both groups were compared as well.

RESULTSIn both groups, the VAS scores significantly decreased after the intervention (P<0.01), while the blood perfusion at the two acupoints significantly increased after intervention (P<0.05); however, the increasement magnitude caused by WCT was obvious compared with JA (P<0.05).

CONCLUSIONSWCT could improve analgesic effects in patients with NT-CS, which might be related to increasing local blood perfusion of acupunct points.

We summarized our experience in transurethral seminal vesiculoscopy (TSV) for recurrent hemospermia by introducing surgical techniques, intraoperative findings, and treatment outcomes. TSV was performed in 419 patients with an initial diagnosis of persistent hemospermia at Shanghai Changhai Hospital (Shanghai, China) from May 2007 to November 2015. TSV was successfully performed in 381 cases (90.9%). Hemospermia was alleviated or disappeared in 324 (85.0%) patients by 3 months after surgery. Common intraoperative manifestations were bleeding, obstruction or stenosis, mucosal lesions, and calculus. Endoscopic presentation of the ejaculatory duct orifice and the verumontanum was categorized into four types, including 8 (1.9%), 32 (7.6%), 341 (81.4%), and 38 (9.1%) cases in Types A, B, C, and D, respectively. TSV is an effective and safe procedure in the management of seminal tract disorders. This study may help other surgeons to become familiar with and improve this procedure. However, further multicentric clinical trials are warranted to validate these findings.

OBJECTIVETo summarize experience of using screws and cement to rebuild tibial bone defect in primary total knee arthroplasty (TKA) and to discuss the relationship between the number of required screws and the severity of tibial bone defects.

METHODSFrom July 2009 to May 2015, 34 patients (40 knees) with varus knees underwent TKA, and the screw and cement technique was used to rebuild medial tibia plateau during operation. There were 8 males (8 knees) and 26 females (32 knees), and the average age was (65.00 +/- 7.25) years old (ranged,55 to 82 years old). One to 6 screws were used in each case. Extension stems were used in 2 cases (4 and 5 screws was used respectively). The area percentages of the bone defects measured as defect area/tibia plateau area, depth of each defect, the number of screws needed in each case, were all used to determine the relationship between the number of screws and the area percentage in certain depth of bone defect by statistic methods, as well as the relationship between screw number and defect depth.

RESULTSAll the patients were followed up and the average duration was 24 months (ranged, 1 to 72 months). The average preoperative HSS score was 43.33 +/- 6.11 (ranged, 32 to 51 scores). Whereas the average postoperative HSS score was 92.15 +/- 4.64 (ranged,83 to 96 scores). The preoperative individual scores including pain, function, activity, nuscle strength, flexion deformity and stability were all improved compared with preoperation,and the differences were statistically significant. All the patients received normal alignment postoperatively, femoraltibial angle was improved from (167.00 +/- 6.39) degrees preoperatively to (175.00 +/- 2.69) degrees postoperatively, the tibial angle was improved from (78.09 +/- 4.51) degrees preoperatively to (88.75 +/- 1.24) degrees postoperatively. Both area percentage and depth of bone defect in a fitting Ologistic model had a significant statistical relationship with the screw number, and a rectangular coordinate system could be formed according to the relationship.

CONCLUSIONScrews and cement technique is a simple, safe and convenient method to rebuild tibial bone defects in primary TKA and its short-term and midterm effect are both reliable. During opera- tion, according to the rectangular coordinate system, the screw number needed in the operation can be inferred form th area and depth of tibia defect, which could have a guiding function in surgery.

Although gene therapy was regarded as a promising approach for glioma treatment, its therapeutic efficacy was often disappointing because of the lack of efficient drug delivery systems. Mesenchymal stem cells(MSCs) have been reported to have a tropism for brain tumors and thus could be used as delivery vehicles for glioma therapy. Therefore, in this study, we attempted to treat glioma by using MSCs as a vehicle for delivering replication-competent adenovirus. We firstly compared the infectivity of type 3, type 5, and type 35 fiber-modified adenoviruses in MSCs. We also determined suitable adenovirus titer in vitro and then used this titer to analyze the ability of MSCs to deliver replication-competent adenovirus into glioma in vivo. Our results indicated that type 35 fiber-modified adenovirus showed higher infectivity than did naked type 3 or type 5 fiber-modified adenovirus. MSCs carrying replication-competent adenovirus significantly inhibited tumor growth in vivo compared with other control groups. In conclusion, MSCs are an effective vehicle that can successfully transport replication-competent adenovirus into glioma, making it a potential therapeutic strategy for treating malignant glioma.
