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.

Tooth extraction is a common and widely employed therapeutic procedure in oral and maxillofacial surgery.Minimally invasive tooth extraction can reduce both physical and psychological trauma to the patients,and is widely recommended as a first-line clinical treatment.But currently no guidelines or consensus has been available to provide a systematic introduction of minimally invasive tooth extraction to guide the clinical practices.To address this issue,this consensus,based on a comprehensive literature review and clinical experiences of experts,systematically summarizes the indications,target patients,and contraindications of minimally invasive tooth extraction,the overall workflow of this procedure(preoperative preparation,surgical steps,postoperative management,postoperative instructions,medications,and follow-up),and its common postoperative complications to provide a comprehensive guidance for clinical application of this technique.

Objective To evaluate the effectiveness and safety of domestically manufactured disposable pressure monitoring sensor in clinical application.Methods The self-parallel control was adopted.A total of 128 patients undergoing surgery for cardiovascular related disease requiring both invasive arterial blood pres-sure and central venous pressure simultaneously monitoring in the two collaborating hospitals of Chongqing Kanghua Zhonglian Cardiovascular Disease Hospital and the Second Affiliated Hospital of Army Medical Uni-versity from January to March 2021 were selected as the study subjects.The two kinds of disposable invasive pressure sensors were simultaneously utilized for continuous monitoring and recording invasive arterial blood pressure and central venous pressure prior to anesthesia induction(T1),at 1 min after the last intravenous an-esthetic drug injection(T2)and at tracheal intubation completion(T3).Additionally,the performance,safety indicators of the product,and success rate of arterial blood collection were recorded.Results At different time points T1,T2 and T3,the the consistency rates of systolic blood pressure measured by two sensors were both 100.0％.The consistency rate of diastolic blood pressure at T1 measured by the two kinds of sensors was 99.2％,which at T2 and T3 was 100.0％.The consistency rates of central venous pressure at 3 time points by the two kinds of sensors were both 100.0％.The correlation coefficient showed that the two kinds of sensors kept the high consistency in measuring systolic blood pressure,diastolic blood pressure and central venous pressure.The concordance rates of arterial blood gas analysis indexes pH,PO2 and PCO2 reached 100.0％,94.5％and 99.2％respectively.Conclusion The effectiveness,accuracy and safety of domestically produced dis-posable invasive blood pressure sensor meet clinical needs.

OBJECTIVE To establish the fingerp rint of decoction pi eces and dispensing granules of Gardenia jasminoides ，to determine the contents of 6 components，so as to evaluate its quality combined with chemical pattern recognition. METHODS High performance liquid chromatography （HPLC）was used. Using geniposide as the reference ，Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 edition）was used to draw the fingerprints of 20 batches of G. jasminoides decoction pieces and 10 batches of G. jasminoides dispensing granules. Similarity evaluation and common peaks identification were conducted. The same HPLC method was adopted to determine the contents of deacetyl asperulosidic acid methyl ester ，geniposide， picrocrocin，rutin，crocin-Ⅰ and crocin- Ⅱ. ORIGIN 9.1 software was used for hierarchical clustering analysis ，and SIMCA 16.0 software was used for principal component analysis （PCA） and partial least squares-discriminant analysis. The differential components affecting the quality of decoction pieces and dispensing granules were screened by taking the variable importance in projection（VIP）value＞1 as the standard. RESULTS There were 24 common peaks for both 20 batches of G. jasminoides decoction piece and 10 batches of G. jasminoides dispensing granules ；a total of 22 common peaks were found in the fingerprints of 30 batches of samples ，and the similarity was not lower than 0.96；six common peaks were identified ，i.e. deacetyl asperulosidic acid methyl ester （peak 2），geniposide（peak 6），picrocrocin（peak 9），rutin（peak 11），crocin-Ⅰ（peak 15），crocin-Ⅱ（peak 17）. Average contents of above 6 components in G. jasminoides decoction pieces were 1.04，57.00，1.30，1.03，9.63 and 0.99 mg/g， respectively；those of G. jasmin oides dispensing granules were 0.96，17.04，0.37，0.27，0.73 and 0.04 mg/g，respectively. PCA results showed that G. jasminoides decoction pieces and G. jasminoides dispensing granules were clustered into respective one category ，which was consistent with results of cluster analysis. There were 9 common peaks with VIP value ＞1， which were 16，14，3，17（crocin-Ⅱ），15（crocin-Ⅰ），18， 22， 2 （deacetyl asperulosidic acid methyl ester） and 21. CONCLUSIONS The estab lished fingerprint and content determination method are simple and reproducible. Combined with chemical pattern recognition ，it can be used to evaluate the quality of decoction pieces and dispensing granules of G. jasminoides . Nine corresponding components represented by peak 16 and so on are the differential components that affect the quality of them.
