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 efficacy of interventional embolization of middle meningeal artery(MMA)for the treatment of chronic subdural hematoma(CSDH).Methods The clinical data of 14 patients with CSDH(17 lesions in total),who were treated with simple embolization of MMA at the Yijishan Hospital of Wannan Medical College of China between July 2021 and July 2022,were retrospective analyzed.After superselective catheterization of MMA using a microcatheter was accomplished,Onyx-18 glue,a liquid embolization agent,was used to embolize the main trunk and the branches of MMA.Imaging follow-up was adopted at 30 days and 90 days after discharge from hospital to evaluate the absorption of hematoma,and the improvement of clinical symptoms was defined as the modified Rankin Scale score(mRS)being decreased≥1 point from the baseline value.Results Successful embolization of MMA was accomplished for all the 17 lesions in the 14 patients,and no procedure-related complications occurred.During the follow-up period,the clinical symptoms and signs were remarkably improved in all patients.The postoperative 90-day hematoma volume was reduced by more than 90%in 11 patients and by more than 40%in one patient,and in 2 patients the postoperative 30-day hematoma volume was reduced by more than 30%.Complete absorption of hematoma was seen in 11 patients,and partial absorption of hematoma was observed in 3 patients.Conclusion For the treatment of newly-developed or recurrent CSDH,interventional embolization of MMA is clinically safe and effective.(J Intervent Radiol,2024,32:12-16)

OBJECTIVE To analyze the current status， hotspots and development trends of research on the treatment of non-alcoholic fatty liver disease （NAFLD）， providing reference for subsequent research. METHODS Searching the Web of Science database， the literature related to the treatment of NAFLD from the establishment of the database to December 31， 2022 were collected. CiteSpace 6.1.R6 was used to construct a visual atlas， perform collaborative network analysis on authors， countries and institutions， and conduct keyword co-occurrence， clustering and emergence analysis to explore its research status and hotspots. RESULTS A total of 3 882 articles were included， and the number of publications had been increasing year by year. The top three countries in terms of publication volume were China， the United States， and Japan. The author with the highest volume of publications was Sanyal from the United States （37 articles）， while the institution with the highest volume of publications was the University of California， San Diego （75 articles）. A closely connected research team abroad mainly conducted large-scale randomized controlled trials （RCT） to evaluate the effectiveness and safety of various interventions， including medication and lifestyle， in treating NAFLD. However， domestic researches mainly focused on basic researches about the treatment of NAFLD with effective medicinal ingredients， and were characterized by traditional Chinese medicine. There were relatively few high-quality large-scale RCT studies related to it. Keyword analysis showed that researches in various countries mainly focused on regulating liver oxidative stress and inflammation， improving the overall balance of glucose and lipid metabolism. Except for hypoglycemic drugs， drugs that act on various comprehensive metabolic homeostasis targets in the body had entered clinical research， and had enormous therapeutic potential. CONCLUSIONS The research on NAFLD treatment continues to grow in popularity and tends to research targets and drugs for regulating systemic metabolic homeostasis. As the main force of research， China should strengthen communication with the international community， grasp the trends and directions of basic research， attach importance to clinical research， and continuously tap the therapeutic potential of traditional Chinese medicine.

Objective:To understand the clinical characteristics of rivaroxban-related adverse events (AE) in perioperative patients.Methods:The relevant databases at home and abroad (as of April 20, 2020) were searched and the case reports of AE associated with rivaroxban used during perioperative period were collected. Relevant information in patients (nationality, gender, age, medical history, application of rivaroxaban, combined drugs, and the occurrence, treatment, and outcome of AE, etc.) was extracted and analyzed descriptively.Results:A total of 42 case reports of AE caused by rivaroxban during perioperative period were collected, involving 46 patients from 11 countries. Of the 46 patients, 25 (54.3%) were male and 21 (45.7%) were female with an age of 16-96 years. In terms of the reasons for medication, 34 patients used rivaroxban before operation for prevention of postoperative venous thrombosis, 7 used rivaroxban after operation for prevention atrial fibrillation, stroke, or systemic thrombosis after operation, 4 discontinued rivaroxban during perioperative period, and 1 did not explain the reason for using rivaroxban. Past medical history were described in 21 patients, including hypertension, hyperlipidemia, and diabetes, etc. Combined medication was described in 22 patients, including antibiotics, non-steroidal anti-inflammatory drugs, analgesics, cardiovascular and cerebrovascular drugs, etc. The onset time of AE was recorded in 31 patients, which was 2 hours to 2 months after medication and most within 1 month. AE associated with rivaroxban were bleeding in 29 patients, liver injury in 7 patients, anaphylaxis in 6 patients, kidney injury in 3 patients, thrombosis in 3 patients, thrombocythemia in 2 patients, thrombocytopenia, pulmonary embolism, acute attack of coronary atherosclerotic heart disease, and visual loss in 1 patient each. After the occurrence of AE, 31 patients were improved after rivaroxban withdrawn, switching to other anticoagulants, and receiving symptomatic treatment; 1 patient improved after changing concomitant medications as well as reducing the dose of rivaroxban; 2 patients did not stop the drug in time and developed new allergic reaction; 2 patients were improved after using rivaroxban again; 1 patient died of hemorrhagic shock due to gastrointestinal bleeding; 9 patients′ outcome were unknown. Among the 46 patients, 18 had medication errors, of which 16 had dose error and 2 had compatibility errors.Conclusions:Hemorrhage is the most common AE related to rivaroxban in the perioperative use of rivaroxban, which mainly occurs within 1 month after medication. The overall prognosis is good after rivaroxban withdrawal, switching to other anticoagulants, and symptomatic treatment. Medication error is one of the causes of AE related to rivaroxban in perioperative period.

Objective: To assess the activity of cathepsin D (CAT-D) and alpha-1 antitrypsin (AAT) in blood in patients with hip or knee osteoarthritis, and to explore whether these two enzymes could be served as serum biomarkers for cartilage degeneration. Methods: hTe activity of CAT-D and AAT in blood serum of 44 women and 26 men with hip or knee osteoarthritis was determined by the method of ELISA before total joint replacement and on the 10th day atfer the surgery. One hundred healthy volunteers were chosen as the control. All datawere analyzed by using SPSS19.0 sotfware. Results: Compared with the controls, the activity of CAT-D in patients with osteoarthritis was decreased by 25% (P<0.05) and 50% (P<0.05) before and atfer the surgery, respectively. hTe activity of AAT in the osteoarthritis patients before the surgery was not signiifcantly changed compared with the control group (P>0.05), but it was increased by 80% after the surgery than that in the control group (P<0.05). hTere was no signiifcant difference in the activities of 2 enzymes between hip and knee osteoarthritis (P>0.05). hTe gender, hypertension, diabetes and age did not affect the activities of the 2 enzymes (P>0.05). Conclusion: AAT might be a possible inflammatory indicator in the osteoarthritis. CAT-D and AAT enzymes are not affected by gender, age, hypertension and diabetes, etc, and they might be served as potential biomarkers for cartilage degradation.

OBJECTIVE To evaluate the therapeutic effect of intranasal endoscopic surgery on inverted papilloma of the nasal cavity and paranasal sinuses in stage Ⅰ-Ⅲ. METHODS According to the staging system developed by John H.Krouse,30 cases with inverted papilloma in the nasal cavity and paranasal sinuses in stage Ⅰ-Ⅲ were analyzed retrospectively. All patients were treated by intronasal endscopic surgery and were followed up for 24 months. RESULTS The inverted papilloma was removed completely and no serious complications occurred. One case recurred at 10 month after surgery and pathologically proved to be cancerated. Another 2 case recurred at 6 and 7 month after surgery respectively. Recurred tumors were removed again, no recurrences occurred in the following up period. The recurrence rate was 10 % and canceration rate was 3.3 %. CONCLUSION Endoscopic surgery is an effective method in management of the inverting papilloma in nasal cavity and paranasal sinuses in stage Ⅰ-Ⅲ.

OBJECTIVETo study the duration of prourokinase gene expression in vein grafts and the role of the prourokinase gene in protecting vein grafts from neointimal hyperplasia.

METHODSFifty-four Wistar rats were used in this study. In each rat, the jugular vein was excised and distended for 30 minutes using a solution containing either Adv(5)-CMV (control group) or Adv(5)-CMV/Pro-UK (treatment group). Next, the jugular vein was reversed and interposed into the divided carotid artery of the same rat. On the 14th day after transfection, vein grafts of the control group were collected in order to perform a fibrinolysis test for prourokinase (Pro-UK) activity. On the 2nd, 7th, 14th, 28th, and 60th day, the vein grafts of the treatment group were likewise collected in order to detect prourokinase activity. On the 28th day, the vein grafts of both groups were explanted to evaluate the (3)H-TDR incorporation so that pathologic analysis could be performed.

RESULTSPro-UK activity could not be detected in the control group, while in the treatment group, the Pro-UK activity could be detected from the 2nd day onwards, peaking on the 7th day and declining from the 14th day, but yet persisting at a low level for a further month. The amount of (3)H-TDR incorporated in the control group was higher than that in the treatment group. Pathologic analysis demonstrated that vein grafts of both groups exhibited wall thickening, but that the degree of graft neointimal hyperplasia and reduction of the graft lumen was greater in the control group than that in the treatment group. The occlusion rate of grafts in the control group was 20%. All grafts in the treatment group were patent.

CONCLUSIONSPro-UK gene transfer before vein grafting in vitro results in a high level of gene expression in the vein graft from the 7th day to 14th day. And its gene expression in the vein graft could reduce neointimal hyperplasia in the vein graft.
