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 systematically evaluate the effects of liraglutide combined with metformin on glucose and lipid metabolism,sex hormones,reproductive function,and gastrointestinal reactions in patients with polycystic ovary syndrome(PCOS).Methods We searched databases such as PubMed,WanFang Medical Network,WanFang Database,China National Knowledge Infrastructure(CNKI),and VIP Journals to collect randomized controlled trials published from January 2011 to August 2022 on the treatment of polycystic ovary syndrome with liraglutide combined with metformin,using Revman 5.4 for the meta-analysis.Results A total of 16 case-control studies were included,involving 1436 patients.Compared to metformin alone,the combination of liraglutide and metformin significantly lowered fasting blood sugar,postprandial blood glucoseafter 2 hours,HbA1c,HOMA-IR,FINS,BMI,as well as LH,FSH,and total testosterone in patients with PCOS.It improved lipid levels,helped establish menstrual cycles,and increased the normal ovulation rate and natural conception rate in these patients.However,there was a significantly higher incidence of gastrointestinal reactions in the liraglutide plus metformin group,and the difference was statistically significant(P＜0.05).Conclusion The combination of liraglutide and metformin can improve glucose and lipid metabolism in patients with polycystic ovary syndrome(PC OS),reduce levels of LH,FSH,and total testosterone,help establish regular menstrual cycles,and increase ovulation and pregnancy rates,but it significantly increases gastrointestinal side effects.

Objective To explore the correlation between speech fluency and diadochokinetic rate in children aged 7～11 years with cochlear implant.Methods Speech samples were collected from 62 children aged 7～11 years with cochlear implant using language retelling task and diadochokinetic rate test task.Their speech rate,articulation rate,syllable duration and pause duration were analyzed.The data were input into ICF converter to obtain the im-pairment limit of each parameter and analyze the speech fluency and diadochokinetic rate characteristics.Partial cor-relation analysis was performed for speech rate,articulation rate,syllable duration and pause duration by two tasks.Results ① For children with cochlear implant,the mean ICF impairment limit of diadochokinetic rate was 1.3± 0.1,the mean ICF impairment limit of fluency in retelling was 1.0±0.3,with various degree of impairment in both tasks.② There was a moderate or low correlation between speech rate,articulation rate,syllable duration in retell-ing task and those in diadochokinetic rate task(0.3＜|r |≤0.8).There was a low correlation between pause dura-tion in retelling task and speech rate and pause duration in diadochokinetic rate task(0.3＜|r |≤0.5).Conclusion The speech fluency and diadochokinetic rate of children aged 7～11 years with cochlear implant is underdeveloped,and the poor articulation movement ability limits their development of speech fluency.

Major depressive disorder (MDD) has become an increasingly serious public health issue, characterized by high incidence and high disability rates. It often coexists with other mental health problems and physical diseases, with a significant negative impact on patients' quality of life. In clinical practice, MDD is considered a heterogeneous disease. The complexity of the pathological mechanisms and the variability in treatment responses lead to a lack of clear therapeutic targets, which complicates the treatment process. In recent years, with advancements in neuroscience, the crucial role of microglia in the pathogenesis of MDD has been revealed. As the main immune cells in the brain, microglia are not only involved in the regulation of neuroinflammation but also play important roles in neurogenesis and neuronal regulation in MDD. This article mainly discusses the role of microglia in the pathophysiological mechanisms of MDD, aiming to provide a theoretical basis for microglia as a potential target for the treatment of MDD.

Objective:To investigate the effect of Early infarct growth rate(EIGR) on the prognosis of patients with acute large vessel occlusive ischemic stroke.Methods:A total of 164 patients with acute large vessel occlusive ischemic stroke were enrolled in the emergency department of the First Affiliated Hospital of Nanjing Medical University from January 1, 2020 to December 31, 2022.According to the change of the National Institutes of Health Stroke Scale (NIHSS) score at admission and 72 h after treatment, the patients were divided into good prognosis group and poor prognosis group. The basic clinical data of the two groups were observed and compared. The risk factors of poor prognosis were analyzed by univariate regression. The effect of EIGR on prognosis after age stratification was further analyzed.Results:Comparing the clinical data of the two groups, there was no difference in EIGR (mL/h) (7.67 vs. 8.24, P=0.211) between the two groups. The product between EIGR and age was included as the interaction term, and the result of the interaction term in the model was statistically significant ( OR=1.002, 95% CI: 1.000-1.003, P=0.032) .Moreover, the result was still statistically significant after adjusting for relevant variables (gender, history of hypertension, history of atrial fibrillation, history of diabetes, history of coronary heart disease, and history of stroke) ( OR=1.002, 95% CI:1.000-1.003, P=0.027). Subgroup analysis was performed according to the median age (71 years). In the elderly group, the proportion of poor prognosis was higher with fast core infarction growth rate defined by 25 mL/h and 15 mL/h ( P < 0.05).In the younger age group, there was no significant difference in the proportion of poor prognosis in the fast core infarction growth rate compared with the slow type ( P > 0.05). Conclusions:EIGR can predict the early clinical outcome early in elderly patients with large vessel occlusive ischemic stroke.

OBJECTIVE: Flavonoids are the bioactive compounds in safflower (Carthamus tinctorius), in which chalcone synthase (CHS) is the first limiting enzyme. However, it is unclear that which chalcone synthase genes (CHSs) are participated in flavonoids biosynthesis in C. tinctorius. In this study, the CHSs in the molecular characterization and enzyme activities were investigated. METHODS: Putative chalcone biosynthase genes were screened by the full-length transcriptome sequences data in C. tinctorius. Chalcone biosynthase genes in C. tinctorius (CtCHSs) were cloned from cDNA of flowers of C. tinctorius. The cloned gene sequences were analyzed by bioinformatics, and their expression patterns were analyzed by real-time PCR (RT-PCR). The protein of CtCHS in the development of flowers was detected by polyclonal antibody Western blot. A recombinant vector of CtCHS was constructed. The CtCHS recombinant protein was induced and purified to detect the enzyme reaction (catalyzing the reaction of p-coumaryl-CoA and malonyl-CoA to produce naringin chalcone). The reaction product was detected by HPLC and LC-MS. RESULTS: Two full-length CtCHS genes were successfully cloned from the flowers of safflower (CtCHS1 and CtCHS3), with gene lengths of 1525 bp and 1358 bp, respectively. RT-PCR analysis showed that both genes were highly expressed in the flowers, but the expression of CtCHS1 was higher than that of CtCHS3 at each developmental stage of the flowers. WB analysis showed that only CtCHS1 protein could be detected at each developmental stage of the flowers. HPLC and LC-MS analyses showed that CtCHS1 could catalyze the conversion of p-coumaryl-CoA and malonyl-CoA substrates to naringin chalcone. CONCLUSION CtCHS1 is involved in the biosynthesis of naringin chalcone in safflower.

Objective:To explore the value of multiparametric ultrasonography consisting of gray-scale ultrasound(US), color Doppler flow imaging (CDFI), real-time strain elastography(RTE), and contrast-enhanced ultrasound(CEUS) in the differential diagnosis of testicular lesions.Methods:Forty patients (40 lesions) detected by ultrasonography examination at the Ultrasound Medical Center of Lanzhou University Second Hospital from June 2020 to June 2022 were retrospectively analyzed, and further the CDFI, CEUS and RTE were performed. The presence of vascularization in the lesion was determined by CDFI and CEUS, avascular lesions were defined as benign, vascularization lesions were defined as malignant. The lesion tissue elasticity was assessed by real-time strain elastography, tissue stiffness was encoded as red(soft), green(intermediate), and blue(hard), and the hard lesions were defined as malignant, soft lesions were defined as benign. All lesions were subjected to pathological histologic examination after surgical resection or puncture biopsy as a reference standard. The correct classification rate, sensitivity, specificity and likelihood ratio of the multiparametric ultrasonography imaging for the diagnosis of benign and malignant testicular lesions were analyzed by ROC.Results:Of 40 testicular lesions, 24 (60.0%) were benign and 16 (40.0%) were malignant. The sensitivity of CDFI, CEUS and RTE in the diagnosis of testicular lesions was 0.875, 1.000 and 1.000, and the specificity was 0.833, 0.750 and 0.708, respectively. The correct classification rate was 85.0%, 85.0% and 82.5%, and the positive likelihood ratio was 5.24, 4.00 and 4.42, respectively. AUC was 0.781, 0.802, 0.771, respectively. By combining RTE and CDFI, a sensitivity of 1.000 and specificity of 0.875 and correct classification rate of 92.8% and positive likelihood ratio of 8.00 and AUC of 0.915 ( P<0.001) were achieved in differentiating testicular lesions. And combining RTE and CEUS, achieved sensitivity of 1.000 and specificity of 0.917 and correct classification rate of 95.0% and positive likelihood ratio of 12.0 and AUC of 0.958( P<0.001). Conclusions:Multiparametric US is of great value in the differential diagnosis of benign and malignant testicular lesions.
