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.

Depression is a common mental illness in adolescents, and some patients do not respond well after medication, which may be partly related to vitamin D deficiency and insufficient calcium intake. This paper reports a 15-year-old patient with depression, whose condition was still unstable and the effect was not good despite routine use of antidepressant drugs and psychological intervention. After adequate supplementation of vitamin D and calcium, the patient's depression improved significantly, and the follow-up for 4 months, the condition was stable and did not recur.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

OBJECTIVETo observe the effect of Schistosoma japonicum cysteine protease inhibitor (rSjCystatin) for treatment of lipopolysaccharide (LPS)-induced sepsis in mice.

METHODSAfter a week of adaptive feeding, 54 BALB/c mice were randomly divided into normal control group (group A), sepsis group (group B), and rSjCystatin intervention group (group C). The mice in group A received an intraperitoneal injection of PBS (100 µL), and those in groups B and C were injected with PBS (100 µL) containing LPS (10 mg/kg); the mice in group C were also intraperitoneally injected with 25 µg sjCystatin in 100 µL PBS 30 min after LPS injection. From each group, 10 mice were randomly selected 24 h after PBS or LPS injection for detecting serum levels of TNF-α, IL-6, and IL-10 using ELISA and the levels of ALT, AST, BUN, and Cr using automatic biochemical analyzer; the pathological changes in the liver, lung and kidney were observed with HE staining. The remaining 8 mice in each group were used for observing the changes in the general condition and the 72-h survival.

RESULTSThe 72-h survival rates of the mice was 100% in group A, 0 in group B, and 36% in group C, showing a significant difference among the 3 groups (P<0.05). Compared with those in group A, the mice in group B exhibited obvious liver, lung, and renal pathologies with increased levels of ALT, AST, BUN, Cr, IL-6, and TNF-α (P<0.05). Treatment with sjCystatin significantly lessened LPS-induced organ pathologies, lowered the levels of liver and renal functional indexes and the pro-inflammatory cytokines, and increased the serum level of IL-10 in the mice (P<0.05).

CONCLUSIONSjCystatin can produce a significant therapeutic effect on sepsis induced by LPS in mice.

Objective To investigate the effects and mechanisms of carbon monoxide-releasing molecule-2 (CORM-2) on LPS induced barrier injure of Caco-2 cells.Methods The model of Caco-2 monolayer cells damage induced by LPS was established by using 50 &mu;g/ml LPS for 24 hours.After preconditioning with different concentrations (10 &mu;mol/L,50 &mu;mol/L,and 100 &mu; mol/L) of CORM-2 for 1 hour,the cultured well-grown Caco-2 monolayer cells were stimulated with 50 &mu; g/ml lipopolysaccharides (LPS) for 24 hour.The 100 &mu;mol/L CORM-2 was put into 37℃ and 5％ CO2 incubator for 18 hours until the CO has been fully released,and it became an inactive CORM-2(iCORM-2).The cultured Caco-2 monolayer cells were divided into six groups:the control group,the LPS group,the LC1(10 &mu;mol /L CORM-2 preconditioning) group,the LC2(50 &mu;mol/L CORM-2 preconditioning) group,the LC3(100 &mu;mol/L CORM-2 preconditioning) group,and the LC4 (iCORM-2 preconditioning) group.The apoptosis rates of different groups of Caco-2 monolayer cells were detected using flow cytometry.Cytokines (TNF-α,IL-1β and HMGB-1) levels of different groups were detected using ELISA kits.The levels of tight junction proteins (occludin ZO-1,claudin-1 and claudin-4) of every group were detected using Western blotting with specific antibodies.The structural changes of tight junction proteins were visualized by immunofluorescence technique.Results Compared with control group,cell apoptosis rate and release of inflammatory cytokines such as TNF-α,IL-1β and HMGB-1 in LPS group were significantly higher,and the levels of tight junction proteins were apparently decreased (P＜0.05) in LPS group.Compared with LPS group,cell apoptosis rate and release of inflammatory cytokines such as TNF-α,IL-1β and HMGB-1 decreased,and the levels of tight junction proteins were attenuated obviously,P＜0.05,in CORM-2 preconditioning groups.And the higher the concentration of CORM-2,the more obvious the protective effects.Conclusions This study demonstrates that CORM-2,as one of exogenous CO-releasing molecules,has the capacity to protect the barrier damage of LPS-stimulated Caco-2 monolayer cells in a concentration dependent manner.The higher the concentration of CORM-2 was,the stronger the protective effects were.The protective effects of CORM-2 include reducing Caco-2 monolayer cells apoptosis rate,inhibiting inflammatory cytokines production and release,and restoring distribution and levels of tight junction proteins.
