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 development of the pancreatic surgeon technique in a high-volume center. Methods: A total of 284 cases receiving pancreatic surgery by a single surgeon from June 2015 to December 2020 were retrospectively included in this study. The clinical characteristics and perioperative medical history were extracted from the medical record system of Zhongshan Hospital,Fudan University. Among these patients,there were 140 males and 144 females with an age (M (IQR)) of 61.0 (16.8) years(range: 15 to 85 years). The "back-to-back" pancreatic- jejunal anastomosis procedure was used to anastomose the end of the pancreas stump and the jejunal wall. Thirty days after discharge,the patients were followed by outpatient follow-up or telephone interviews. The difference between categorical variables was analyzed by the Chi-square test or the CMH chi-square test. The statistical differences for the quantitative data were analyzed using one-way analysis of variance or Kruskal-Wallis H test and further analyzed using the LSD test or the Nemenyi test,respectively. Results: Intraoperative blood loss in pancreaticoduodenectomy between 2015 and 2020 were 300,100(100),100(100),100(0),100(200) and 150 (200) ml,respectively. Intraoperative blood loss in distal pancreatectomy was 250 (375),100 (50),50 (65), 50 (80),50 (50),and 50 (100) ml,respectively. Intraoperative blood loss did not show statistical differences in the same operative procedure between each year. The operative time for pancreaticoduodenectomy was respectively 4.5,5.0(2.0),5.5(0.8),5.0(1.3),5.0(3.3) and 5.0(1.0) hours in each year from 2015 to 2020,no statistical differences were found between each group. The operating time of the distal pancreatectomy was 3.8 (0.9),3.0 (1.5),3.0 (1.8),2.0 (1.1),2.0 (1.5) and 3.0(2.0) hours in each year,the operating time was obviously shorter in 2018 compared to 2015 (P=0.026) and 2020 (P=0.041). The median hospital stay in 2020 for distal pancreatectomy was 3 days shorter than that in 2019. The overall incidence of postoperative pancreatic fistula gradually decreased,with a incident rate of 50.0%,36.8%,31.0%,25.9%,21.1% and 14.8% in each year. During this period,in a total of 3,6,4,2,0 and 20 cases received laparoscopic operations in each year. The incidence of clinically relevant pancreatic fistula (grade B and C) gradually decreased,the incident rates were 0,4.8%,7.1%,3.4%,4.3% and 1.4%,respectively. Two cases had postoperative abdominal bleeding and received unscheduled reoperation. The overall rate of unscheduled reoperation was 0.7%. A patient died within 30 days after the operation and the overall perioperative mortality was 0.4%. Conclusion: The surgical training of a high-volume center can ensure a high starting point in the initial stage and steady progress of pancreatic surgeons,to ensure the safety of pancreatic surgery.

Clinical pathway is an important quality management tool for regulating medical behavior both at home and abroad, and an important means of controlling medical costs in the reform of medical insurance payment methods.The author reviewed the current development status of clinical pathways both at home and abroad, focusing on summarizing the development experience of foreign countries, and analyzing the shortcomings in the development of clinical pathways in China from the perspectives of formulation, implementation, and evaluation. It is proposed that China should establish and improve the regulatory and incentive mechanisms for clinical pathways, accelerate the construction of supporting medical security systems, explore new incentive transmission models, attach importance to the role of patient participation in the formulation and implementation of clinical pathways, and so on, in order to provide reference for promoting the efficient development of clinical pathways in China.

Although the guiding principles for molecular identification of traditional Chinese medicines (TCM) using DNA barcoding have been recorded in the Chinese Pharmacopoeia, there is still a lack of systematic research on its application to commercial TCM decoctions. In this study, a total of 212 commercial TCM decoctions derived from different medicinal parts such as root and rhizome, fruit and seed, herb, flower, leaf, cortex, and caulis were collected to verify applicability and accuracy of the method. DNA barcodes were successfully obtained from 75.9% (161/212) of the samples, while other samples failed to be amplified due to genomic DNA degradation. Among the 161 samples, 85.7% of them were identified as recorded species in the Chinese Pharmacopoeia (2020 edition). In addition, 14 samples could be identified as species recorded in the Chinese Pharmacopoeia and their closely related species in the same genus. Morphological identification for the unconfirmed samples showed that eight were genuine species and three were adulterants, while the other three were unidentifiable due to lack of morphological characteristics. Furthermore, the DNA barcodes of seven samples accurately mapped to the sequences of adulterants. Remarkably, counterfeit products were detected in two samples. These results demonstrate that DNA barcoding is suitable for the identification of commercial TCM decoctions. The method can effectively detect adulterants and is appropriate for use throughout the industrial chain of TCM production and distribution, and by the supervisory agencies as well.

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.

Objective To evaluate the role of minimum apparent diffusion coefficient(MinADC) values in peritumoral edema based on magnetic resonance diffusion weighted imaging in the differential diagnosis between primary central nervous system lymphoma(PCNSL) and glioblastoma(GBM).Methods ADC values in peritumoral edema were measured in 16 patients with PCNSL(diffuse large B cell lymphoma) and 31 patients with GBM(WHO grade 4) confirmed by pathology.Regions of interests were manually drawn on ADC maps on peritumoral edema regions to obtain the MinADC value.Independent samples t-test and receiver operating characteristic analysis were performed for statistical analysis.Results The MinADC value [(1.20-1.45)×10 mm/s,mean(1.35±0.68)×10 mm/s] in PCNSL was significantly higher than that in GBM [(0.95-1.31)×10 mm/s,mean(1.12±0.09)×10 mm/s](t=9.977,P=0.000).The area under the receiver operating characteristic curve was 0.986,and the cutoff value of MinADC was 1.245×10 mm/s for the differentiation between PCNSL and GBM,with the best combination of sensitivity(94.1%) and specificity(94.1%).Conclusion MinADC value can be a simple and effective measure for the differential diagnosis between PCNSL and GBM.

Objective To compare urodynamic studies (UDS) and perineal sonography for assessing mixed urinary incontinence (MUI) in women. Methods A total of 118 adult females with MUI and 30 controls were enrolled from September, 2010 to December, 2017. Their baseline clinical characteristics were recorded. The MUI patients were divided into stress-predomi-nant (S-MUI, n=51), urge-predominant (U-MUI, n=34) and equal predominance (E-MUI, n=33) according to King's Health Questionnaire. Both UDS and perineal sonography were performed in all the subjects. Tolerability of the two methods was compared. Results For sonography parameters, compared with the controls, S-MUI patients had greater dynamic posterior urethral angle, dynamic angle of urethral inclination, dynamic pubo-urethral distance and descent of bladder neck (P<0.001), U-MUI patients had greater detrusor thickness (P<0.05), and E-MUI patients had greater descent of blad- der neck (P<0.05). For UDS parameters, compared with the controls, S-MUI patients had lower Pure.clos.max and functional urethral length; U-MUI patients had lower Qmax, smaller bladder volume, higher Pdet.open, high-er Pdet.Qmax and higher incidence of detrusor overactivity; and E-MUI patients had higher Pdet.Qmax and low-er Pure.clos.max (P<0.05). All UDS and sonography parameters differed significantly between S-MUI and U-MUI patients. The descent of the bladder neck, dynamic angle of urethral inclination, and dynamic puboure-thral distance were negatively correlated with detrusor pressure at maximal flow and functional urethral length, while detrusor wall thickness was positively correlated with detrusor pressure at maximal flow and functional urethral length. Perineal ultrasound was better tolerated than UDS in 82.3% patients. Conclusion Perineal sonography parameters show good correlation with UDS parameters. Ultrasonography is better tol-erated than UDS and provides additional morphologic data. Perineal sonography could facilitate to diagnose U-MUI.

Objective To cxplore the optimal levels of serum calcium,phosphorus and intact parathyroid hormone (iPTH) in peritoneal dialysis (PD) patients.Methods This study is a single center,retrospective cohort study.The associations between serum calcium,phosphorus and iPTH and all-cause mortality in 217 PD patients were analyzed.All patients started PD between January 1,2008 and April 30,2016 were enrolled and followed up to December 31,2016.At baseline and every 3 months,biochemical and therapeutic information was collected.Cox proportional hazard regression models and cubic splines analysis were employed to assess the lowest mortality risk ranges in serum markers of bone metabolism.Results There was no significantly difference between patients within target ranges based on KDOQI or KDIGO guideline and those outside the target ranges by Kaplan-Meier survival analysis.The lowest mortality risk ranges were 2.17-2.40 mmol/L for serum calcium,1.20-1.67 mmol/L for serum phosphorus and 180-350 ng/L for serum iPTH by using Cox models and cubic splines analysis.Moreover,cumulate survival had significant difference between patients within the descriptive ranges and those out of the descriptive ranges at time-averaged values but not at baseline values.Conclusions The optimal time-averaged ranges of PD patients are 2.17-2.40mmol/L for serum calcium,1.20-1.67 mmol/L for serum phosphorus and 180-350 ng/L for serum iPTH.These ranges need further validation by large population studies to further conform.
