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.

BACKGROUND: Previous evidence showed that ambient air pollution and cardiovascular mortality are related. However, there is a lack of evidence towards the modification effect of long-term lifestyle on the association between short-term ambient air pollution and death from cardiovascular events. METHOD: A total of 14,609 death from major adverse cardiovascular events (MACE) were identified among the China Kadoorie Biobank participants from 2013 to 2018. Ambient air pollution exposure including particulate matter 2.5 (PM_2.5), SO₂, NO₂, CO, and O₃ from the same period were obtained from space-time model reconstructions based on remote sensing data. Case-crossover design and conditional logistic regression was applied to estimate the effect of short-term exposure to air pollutants on MACE mortality. RESULTS: We found MACE mortality was significantly associated with PM_2.5 (relative percent increase 2.91% per 10 µg/m³ increase, 95% CI 1.32-4.53), NO₂ (5.37% per 10 µg/m³ increase, 95% CI 1.56-9.33), SO₂ (6.82% per 10 µg/m³ increase, 95% CI 2.99-10.80), and CO (2.24% per 0.1 mg/m³ increase, 95% CI 1.02-3.48). Stratified analyses indicated that drinking was associated with elevated risk of MACE mortality with NO₂ and SO₂ exposure; physical inactivity was associated with higher risk of death from MACE when exposed to PM_2.5; and people who had balanced diet had lower risk of MACE mortality when exposed to CO and NO₂. CONCLUSIONS The study results showed that short-term exposure to ambient PM_2.5, NO₂, SO₂, and CO would aggravate the risk of cardiovascular mortality, yet healthy lifestyle conduct might mitigate such negative impact to some extent.

Objective:To compare the efficacy and safety of Changsulin ? with Lantus ? in treating patients with type 2 diabetes mellitus (T2DM). Methods:This was a phase Ⅲ, multicenter, randomized, open-label, parallel-group, active-controlled clinical trial. A total of 578 participants with T2DM inadequately controlled on oral hypoglycemic agents were randomized 3∶1 to Changsulin ? or Lantus ? treatment for 24 weeks. The efficacy measures included changes in glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2h postprandial plasma glucose (2hPG), 8-point self-monitoring of blood glucose (SMBG) profiles from baseline, and proportions of subjects achieving targets of HbA1c and FPG. The safety outcomes included rates of hypoglycemia, adverse events (AEs) and anti-insulin glargine antibody. Results:After 24 weeks of treatment, mean HbAlc decreased 1.16% and 1.25%, FPG decreased 3.05 mmol/L and 2.90 mmol/L, 2hPG decreased 2.49 mmol/L and 2.38 mmol/L in Changsulin ? and in Lantus ?, respectively. No significant differences could be viewed in above parameters between the two groups (all P>0.05). There were also no significant differences between Changsulin ? and Lantus ? in 8-point SMBG profiles from baseline and proportions of subjects achieving the targets of HbA1c and FPG (all P>0.05). The rates of total hypoglycemia (38.00% and 39.01% for Changsulin ? and Lantus ?, respectively) and nocturnal hypoglycemia (17.25% and 16.31% for Changsulin ? and Lantus ?, respectively) were similar between the two groups (all P>0.05). Most of the hypoglycemia events were asymptomatic, and no severe hypoglycemia were found in both groups. No differences were observed in rates of AEs (61.77% vs.52.48%) and anti-insulin glargine antibody (after 24 weeks of treatment, 6.91% vs.3.65%) between the two groups (all P>0.05). Conclusions:Changsulin ? shows similar efficacy and safety profiles compared with Lantus ? and Changsulin ? treatment was well tolerated in patients with T2DM.

BACKGROUND AND PURPOSE: Both genetic factors and smoking are associated with ischemic stroke (IS) risk. However, little is known about the potential interaction of these factors. We aimed to assess whether smoking and a positive family history interact to increase the risk of IS. METHODS: The nationwide prospective study recruited 210,000 men and 300,000 women in 2004 to 2008 at ages 30 to 79 years. During 9.7 years of follow-up, we documented 16,923 and 20,656 incident IS cases in men and women without major chronic diseases at baseline, respectively. Multivariable Cox regression models were used to examine associations between family history and IS. Likelihood ratio tests were used to test the smoking-family history interactions on IS. RESULTS: About 67.8% (n=135,168) of men ever smoked regularly compared with 2.7% (n=7,775) of women. Among men, a significant interaction between family history and smoking on IS was observed (P for interaction=0.03), with more pronounced association between family history and IS among ever-regular smokers (hazard ratio [HR], 1.21; 95% confidence interval [CI], 1.16 to 1.27) than among never-smokers (HR, 1.11; 95% CI, 1.01 to 1.23). The association between family history and IS among ex-smokers after more than 10 years of cessation (HR, 1.01; 95% CI, 0.85 to 1.20) appeared similar to that among never-smokers. Among women, a similar but not significant interaction between family history and smoking on IS was observed. Ever-regular smokers who had a family history of stroke had the highest risk of IS. CONCLUSIONS: Among Chinese men, the association of family history with IS was accentuated by smoking, and such accentuation tended to be lowered by cessation.

Objective To study the clinical significance of antinuclear antibody (ANA),anti-thyroid peroxidase antibody (TPO-Ab) and antithyroglobulin antibody (Tg-Ab),thyroid stimulating hormone (TSH),free triiodothyronine (FT3),free thyroxine (FT4) in patients with recurrent spontaneous abortion (RSA).Methods 46 women with RSA diagnosis in out patient department in Peking University Shenzhen Hospital from March 2015 to December 2016 were recruited as the study group,20 women with normal childbirth history were enrolled as the control group,ANA was detected by indirect immunofluorescence (IIF) assay and ELISA,TSH,FT3 and FT4 were detected by chemiluminescence immunoassay technology.Results The positive rates of ANA(IIF),TPO-Ab and Tg-Ab in patients with RSA were 24％,24％ and 15％ respectively which were significantly higher than those in healthy control (P＜0.05).Serum levels of TSH,TPO-Ab and Tg-Ab in patients with RSA were 2.70 ± 1.38 mIU/L,38.99 ± 10.18 IU/ml and 3.07 ± 1.69 IU/ml respectively,which were significantly higher than those in healthy cases (P＜0.05).Conclusion ANA and antithyroid antibodies were closely related with RSA.It is very important to screen ANA and antithyroid antibodies for etiological diagnosis and appropriate intervention in patients with RSA to reduce the incidence of abortion.

Objective Long non-coding RNA(lncRNA),with more than 200 nucleotides in length,is closely related to many endocrine and metabolic diseases as a functional RNA.Researches has shown that lncRNA can regulate gene expression in multiple levels,including participation in chromatin imprints,in combination with apparent modified complexes or transcription factors to play a transcriptional regulation,and binding with miRNA,mRNA or protein to play the role of post-transcriptional regulation.The disorder of lncRNA expression and the mutation of the primary sequence or variation of the secondary structure are associated with many human diseases.The study of lncRNA in diabetic kidney disease is still in its infancy.In addition,since some lncRNA can be detected in human body fluid and have good specificity and accessibility,it is speculated that lncRNA can be used as a new potential biomarker for the diagnosis and prognosis of diabetic kidney disease.

Objective To explore the clinical application value of 64-layer spiral CT three-dimensional imaging in sty-loid process syndrome. Methods Imaging data of three-dimensional imaging of 42 patients with styloid process syn-drome who were examined from 2013 to 2014 were collected and retrospectively analyzed. The thickness and spacing of scanning layer were both 1 mm, and the tread pitch was 1. Reconstruction techniques of MIP and VR were applied for processing. Results Three-dimensional images of 42 patients(MIP image,VR image)all distinctly manifested the over-all picture of styloid process and imaging findings. Conclusion The combined application of MIP and VR reconstruc-tion techniques, as well as the comprehensive analysis of axial imaging are able to significantly improve the accurate diagnosis of styloid process syndrome via spiral CT, which provides significant values for clinical diagnosis of diseases and surgery.

Objectives To investigate the epidemiological and clinical characteristics of dyslipidemia as well as its treatment and influence on accompanying diseases in impaired glucose status among inpatients. Methods A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day in 2004. The fasting blood glucose (FBG), lipid profiles, BMI, waist to hip ratio (WHR) and concomitant disorders of the first screen during the hospitalization period were recorded. Those who had FBG level from 5.6 to 6. 9 mmol/L and not been previously diagnosed diabetes (PDM) underwent oral glucose tolerance test (OGTF). Results Of the 8753 inpatients investigated, 1067 eases had complete medical records(CMR case) including PDM cases and previously non-diagnosed diabetes ones with FBG ≥ 5. 6 mmol/L. Of the previously non-diagnosed diabetes cases with FBG levels from 5.6 to 6.9 mmmol/L, 65.8% accepted OGTT. Of the CMR cases, 41.9% had PDM, 21.7% was newly diagnosed diabetes mellitus (NDM), 29. 1% had impaired glucose regulation (IGR) and only 7.3% had normal glucose tolerance (NGT). The TG levels in NDM and PDM group were higher than those in IGR and NGT group (P < 0.05, respectively). The HDL-C levels in IGR, NDM and PDM group were lower than those in NGT group (P < 0.05, respectively). Sixty-nine point six percent of the diabetes mellitus (DM) inpatients was accompanied with dyslipidemia and the rate was higher than those in NGT (56.4%) and IGR inpatients (52.5%, P <0.05, respectively). Only 22. 8% of the PDM inpatients underwent treatment of dyslipidaemia and just 3.4% achieved the target suggested by the guideline of ATP-Ⅲ. BMI was higher and waistline longer in the PDM and NDM inpatients than those in the NGT cases (P <0.05, respectively). Seventy-two point eight percent of the PDM inpatients was complicated with more than one type of vascular diseases. Nine point seven percent and 0. 2% of the NDM inpatients were tormented by diabetic nephropathy and diabetic retinopathy respectively. Conclusions More inpatients with accompany DM or IGR had concomitant dyslipidemia than those with NGT, which included hypertriglyccridemia, hypo-high-density lipoproteinemia and metabolic syndrome. Concomitant vascular diseases were more frequently found in PDM inpatients than in the others. Some of the NDM and IGT inpatients were complicated with microvascular diseases.
