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.

Primary endometrioid adenocarcinoma of the rectovaginal septum is rare. Its pathogenesis is not clear and there is no standard treatment. One patient with endometrioid adenocarcinoma of the rectovaginal septum arising from deep infiltrative endometriosis was admitted to Qingdao Municipal Hospital. The patient presented with incessant menstruation and abdominal distension. She had bilateral ovarian endometriotic cystectomy 6 years ago. Imaging findings suggested a pelvic mass which might invade the rectovaginal septum. Pathological results of primary surgery confirmed endometrioid carcinoma of the pelvic mass arising from the rectovaginal septum. Then she had a comprehensive staged surgery. Postoperative chemotherapy was given 6 times. No recurrence or metastasis was found during the 2-year follow-up. The possibility of deep infiltrating endometriosis and its malignant transformation should be considered in the differential diagnosis of a new extragonadal pelvic lesion in a patient with a history of endometriosis, which would avoid misdiagnosis and missed diagnosis.

Objective Cisplatin(DDP)is widely used in the chemotherapy of lung cancer. However, cisplatin resistance represents a major obstacle in its effective treatment. Our preliminary work has demonstrated that inactivated Sendai virus(HVJ-E)shows that it induces apoptosis in murine melanoma cells(B16)and obviously inhibites the tumor growth in tumor-bearing BALB/c nude mice. This study aims to investigate whether inactivated HVJ-E has an effect of inducing apoptosis in cisplatin-resistant A549/DDP lung adenocarcinoma cells in vitro and in vivo. Methods HVJ-E and A549/DDP cells were co-cultured in vitro,and the effect of HVJ-E on the apoptosis in A549/DDP cells was detected by flow cytometry. In addition,HVJ-E was injected into the tumor in vivo, and its oncolytic effect was observed by TUNEL assay of tissue sections and measurement of tumor size. Results After co-cultured with HVJ-E for 12 h,24 h and 36 h, the apoptosis rate of A549/DDP cells in late stage detected by flow cytometry was 7.7%, 12.6% and 18.9%,respectively,showing a significant difference between 12 h and 24 h, and between 24 h and 36 h. TUNEL assay showed that there was more apoptosis in tumor cells in vivo in the experimental group than in the control group. Meanwhile, intratumoral injection of HVJ-E induced a significantly smaller tumor volume in the experimental group compared with the control group(P ﹤ 0.05). Conclusions Our findings indicate that inactivated HVJ-E can induce apoptosis in A549/DDP cells both in vitro and in vivo, and intratumoral injection of inactivated Sendai virus significantly reduces the tumor growth in vivo.

Objective To evaluate bone cement longer handle artificial femoral head replacement treatment the clinical effect of the treatment of femoral fractures between rotor-instability.Methods There were 98 patients with fracture of instability-between the femur rotor ,women 60 cases,38 cases,male,aged 75 to 94 years old,average 83.5 years.Fractured by Tronzo-Evans type III 56 cases,type IV 42 cases.All use of bone cement longer handle arti-ficial femoral head replacement therapy ,to observe clinical therapeutic effect .Results All cases of postoperative X-ray showed both fracture reduction and fixation well between the rotor and prosthesis position is good .96 cases of post-operative for 6 to 24 months followed-up,the average 15 months.Harris score was 85.4%.Conclusion Bone cement longer handle artificial femoral head replacement has quick postoperative functional recovery ,weight-bearing activities earlier,which can avoid the advantages of long-term complications in bed ,instability is treatment of older femoral frac-tures between rotor reasonable operation method .
