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 diagnostic value of gastrin?17( G?17) and pepsinogen( PG) for gastric cancer. Methods A multicenter cross?sectional study of patients with continuous stomach discomfort from four centers including Changhai Hospital Affiliated to Second Military Medical University, the First Hospital Affiliated to Anhui Medical University, Qinghai Provincial People′s Hospital and the First Hospital Affiliated to Zhejiang University of Chinese Medicine from May 2014 to September 2015 was conducted. Before gastroscopy, fasting serum gatrin?17 and pepsinogen were analyzed by enzyme?linked immunosorbent assay(ELISA). The efficacy of G?17 and PG were evaluated according to endoscopic and pathological results. Results Based on the results of the pathological diagnosis, 1 122 cases were enrolled and divided into chronic atrophic gastritis group ( 548 cases ) , chronic non?atrophic gastritis group ( 370 cases), and gastric cancer group(204 cases). Serum G?17 and PGⅡ levels significantly increased(P<0?05) and PGR significantly decreased( P<0?05) in gastric cancer group compared with other groups. There was no significant difference in PGⅠlevel among three groups. The cut?off value of G?17 to diagnose gastric cancer was 7 pmol/L. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of G?17 for gastric cancer were 59?31%, 70?59%, 68?54%, 30?95% and 88?65% respectively. The cut?off value of PG Ⅰ/PG Ⅱ( PGR ) to diagnose gastric cancer was 7. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PGR for gastric cancer were 41?18%, 83?01%, 75?40%, 35?00% and 86?39% respectively. The cut?off value of PGⅡto diagnose gastric cancer was 10 μg/L. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PGⅡfor gastric cancer were 73?53%, 53?05%, 56?77%, 25?82% and 90?02% respectively. If G?17>7 pmol/L and PGR<7 was regarded as the cut?off value of diagnosis of gastric cancer, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 25?00%, 91?29%, 79?23%, 38?93%and 84?56%respectively. If G?17>7 pmol/L and PGⅡ>10μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 48?04%, 79?74%, 73?98%, 34?51% and 87?35% respectively. If PGR<7 and PGⅡ>10 μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 33?82%, 84?86%, 75?58%, 33?17% and 85?23% respectively. Based on logistic regression analysis of the independent variables of high serum G?17 value(>7 pmol/L), low serum PGR value(<7) and high serum PGⅡvalue(>10 μg/L), their OR value were 2?592, 2?237 and 1?864 respectively, and high serum G?17 value showed the highest risk of gastric cancer. Conclusion High serum G?17 and PGⅡ, low PGR are indicators of gastric cancer. Combination of G?17 and PGR has the best diagnostic value for gastric cacer. Gastric cancer can be screened in large scale by combining G?17 and PGR in order to improve the early diagnostic rate of gastric cancer and reduce the mortality of gastric cancer in our country.

Aim To investigate the effect of piperine (PIP)on triglycerides(TG),free fatty acid(FFA), tumor necrosis factor-α(TNF-α)and leptin of model rats with insulin resistance syndrome(IRS).Methods By feeding rats with high-fat,high-glucose and high-salt diet,IRS model rats were established.Triglycer-ides(TG)was observed dynamically every 4 weeks, treating on the 4th weeks and 8 weeks continuously. TG (method of GOD-POD),FFA (method of colori-metric),TNF-αand leptin (method of ELISA)were measured.Results After 8 weeks treatment,the level of TG,FFA,TNF-αand leptin in PIP group decreased obviously,while it increased in model group signifi-cantly.Conclusions PIP could reduce TG and FFA and improve abnormal lipid metabolism of model rats with IRS significantly.Perhaps the mechanism is relat-ed with the down-regulation of cytokine TNF-αand leptin.

Allergic rhinitis (AR) is a noninfectious inflammatory response in nasal mucosa caused by allergens, which is contacted by a specific individual. The immune imbalance of Th1/Th2 plays an important role in the pathogenesis of AR. In?terleukin (IL)-33, the novel cytokine of IL-1 family, is an important regulatory factor of allergic diseases, autoimmune diseas?es and various inflammatory diseases. IL-33 is a kind of alarm, which is mainly secreted and released by damaged tissues and cells, especially impaired epithelial cells and endothelial cells. IL-33 binding to its receptor ST2L can activate a variety of immune cells to produce Th2 cytokines, precipitating and maintaining Th2 polarization, increasing AR immune inflamma?tion, which is the new target of AR in research and treatment. In this article, we have done a brief overview for the biological functions of IL-33 and its receptor ST2L and the research progress in the AR.

To discover the novel compounds with biological activity, N-hetercycle substituted derivatives were synthesized based on the structure of benzofuran. A series of novel N-hetercycle substituted benzofuran derivatives(2a-2j)were synthesized by the reaction of 2-(4′-florobenzoyl)benzofuran with N-heterocyclic compounds. And the structures were characterized by 1H NMR, 13C NMR and HRMS. Their anti-tumor activities were studied in vitro against a panel of human tumor cell lines(HeLa, A549 and H1975)by the MTT assay. The results indicate that compounds 2a, 2f and 2j are the most potent within this series of compounds against human tumor cell lines, showing that they are promising lead compounds for further structural modifications and biological evaluation.

OBJECTIVE: To study the expression of IL-33 and its receptor ST2 in the nasal mucosa of allergic rhinitis (AR) patients, and to explore the role of IL-33 and ST2 in the pathogenesis of AR. METHOD: Collected 24 cases of nasal septum deviation of patients with AR as AR group,and selected 20 patients with simple septum deviation as normal control. In addition, collected 20 cases diagnosed with AR, who accepted standardized specific immunotherapy(SIT). RESULT: Immunohistochemical results found more positively stained cells of IL-33 and ST2 in AR patients than normal control group, the difference was statistically significant (P < 0.05), Western-Blot detected that IL-33 and ST2 protein level were significantly higher in AR than the normal control group (P < 0.01), PCR detected that the expression of IL-33mRNA and ST2mRNA were increased in AR group compared with the control group, the difference was statistically significant (P < 0.05). While, the serum IL-33 levels in AR were decreased before treatment (72.37 ± 16.18) ng/L than after six months of SIT (47.35 ± 10.59) ng/L,and the difference was statistically significant (P < 0.05). CONCLUSION IL-33 and its receptor ST2 were highly expressed in the nasal mucosa of patients with AR, suggesting that IL-33/ST2 may play an important role in the pathogenesis of allergic rhinitis. Serum levels of IL-33 were significantly decreased after SIT treatment, suggesting that IL-33 may have a positive correlation with the severity of AR.
