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 This study aimed to clarify the intervention effect of salidroside(SAL)on lung injury caused by PM2.5 in mice and illuminate the function of SIRT1-PGC-1ɑ axis. Methods Specific pathogen-free(SPF)grade male C57BL/6 mice were randomly assigned to the following groups:control group,SAL group,PM2.5 group,SAL+PM2.5 group.On the first day,SAL was given by gavage,and on the second day,PM2.5 suspension was given by intratracheal instillation.The whole experiment consist of a total of 10 cycles,lasting 20 days.At the end of treatment,blood samples and lung tissues were collected and analyzed.Observation of pathological changes in lung tissue using inverted microscopy and transmission electron microscopy.The expression of inflammatory,antioxidants,apoptosis,and SIRT1-PGC-1ɑ proteins were detected by Western blotting. Results Exposure to PM2.5 leads to obvious morphological and pathologica changes in the lung of mice.PM2.5 caused a decline in levels of antioxidant-related enzymes and protein expressions of HO-1,Nrf2,SOD2,SIRT1 and PGC-1ɑ,and an increase in the protein expressions of IL-6,IL-1β,Bax,caspase-9 and cleaved caspase-3.However,SAL reversed the aforementioned changes caused by PM2.5 by activating the SIRT1-PGC-1α pathway. Conclusion SAL can activate SIRT1-PGC-1ɑ to ameliorate PM2.5-induced lung injury.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To assess the effects of intervention measures on the quality control of health examination institutions in Dalian City.Methods:This cross-sectional study encompassed a comprehensive evaluation of 40 physical examination institutions in Dalian City. Interrupted time series analysis was employed to examine the changes in level and slope of processing rates for significant abnormal health examination results, chief inspection physician qualification rates, and completion rates of basic health examination items before (January 2020 to July 2021) and after (August 2021 to July 2022) intervention.

Objective: To explore the distribution patterns of cardiometabolic diseases (CMD) in elderly patients with colorectal cancer, and provide a reference for the prevention and treatment of cardiovascular metabolic diseases in these patients. Methods: Clinical data of 3 894 elderly patients with colorectal cancer from January 2008 to March 2018 admitted in the Chinese PLA General Hospital were recruited and the incidence rate of CMD was retrospectively analyzed. The influence factors of elderly patients with colorectal cancer combined with CMD were analyzed by multivariate Logistic regression model. Results: The morbidity rate of CMD in elderly patients with colorectal cancer is 33.4% (1 301/3 894), among them, the morbidity rate of the male was 31.9% (768/2 409), and that of the female was 35.9% (533/1 485). There was not significant difference between these two sex (P=0.074). The morbidity rates of CMD in patients of 65-74 years, 75-84 years and ≥85 years were 30.6% (754/2 462), 37.0% (479/1 294) and 49.3% (68/138), respectively, with significant differences (P<0.001). Multiple Logistic regression analysis revealed that female (OR=1.213, 95%CI: 1.056-1.394), age (75-84 years group: OR=1.344, 95%CI: 1.164-1.552; ≥85 years group: OR=2.345, 95%CI: 1.651-3.331) and body mass index (BMI 18.5-24.9 kg/m(2) group: OR=1.319, 95%CI: 1.065-1.638; ≥25 kg/m(2) group: OR=2.041, 95%CI: 1.627-2.561) were independent risk factors for elderly colorectal cancer patients with CMD. Conclusion: The morbidity rate of CMD in elderly patients with colorectal cancer increases with age and it is urgent to strengthen multidisciplinary cooperation and develop reasonable treatment plans to extend the survival and life quality of these patients.

Depression is a mental illness characterized by persistent negative feelings， which has seriously threatened people's health. In recent years， neuronal autophagy， an important stress response， has also been regarded as a hypothesis for the pathogenesis of depression. Relevant studies have shown that either insufficient or excessive autophagy triggers neuronal damage， and activated or inhibited neuronal autophagy can be observed in animal models of depression. Therefore， neuronal autophagy may be a double-edged sword involved in the pathogenesis of depression. It is believed in traditional Chinese medicine （TCM） that the occurrence of this disease is closely related to liver depression and spleen deficiency. Chinese medicine regulates the neuronal autophagy via multiple ways. The TCM monomers that regulate neuron autophagy are capable of protecting nerves or penetrating the blood-brain barrier. TCM compounds designed for soothing liver or invigorating spleen have been proved effective against this disease， demonstrating that the core pathogenesis of depression lies in liver depression and spleen deficiency. The regulatory effects of TCM on neuronal autophagy in depression models might result from its action on multiple targets， multiple pathways， and multiple systems. This paper discussed the limitations in current research based on the involvement of neuronal autophagy in depression and its treatments， in order to provide ideas for later similar research and that concerning TCM treatment of depression.

Objective:To investigate the effect of ultrasound-guided midline catheter placement on the incidence of catheter-related bloodstream infection (CRBSI) in severe emergency patients.Methods:Five hundred and twenty-nine patients were chosen as the research objects from March 2018 to December 2019 at Emergency Intensive Care Unit, which was divided into the experimental group ( n=278) and the control group ( n=251). In the experimental group, ultrasound-guided midline catheter was used as central venous catheter (CVC) removal method of sequential, and in the control group, peripheral venous indwelling needle was used as sequential method after removal of CVC. CVC, midline catheter and the indwelling time of indwelling needle were counted. The utilization rate of CVC was compared between the two groups. Kaplan-Meier survival curve was plotted to describe the CVC indwelling time of the two groups and log-rank test was performed. Cox regression analysis was performed to analyze the influencing factors of CVC indwelling time and compare the incidence of CRBSI and other catheter-related complications. Results:The CVC indwelling time of the experimental group was significantly shorter than that of the control group (8 d vs. 13 d, P=0.000). The CVC utilization rate of the experimental group was significantly lower than that of the control group (49.83% vs. 80.45%, P=0.000). Multivariate Cox regression analysis showed that difficult intravenous access, length of ICU stay, the site of catheter placement, and midline catheter implantation without ultrasound-guidance were independent risk factors for prolonged CVC indwelling time ( P=0.000). The CRBSI rate of the experimental group was significantly lower than that of the control group (0.571‰ vs. 3.802‰, P=0.038). There was no significant difference in the incidence of other catheter-related complications between the two groups ( P=0.403). Conclusions:Ultrasound-guided midline catheter implantation can shorten the indwelling time of CVC, reduce the utilization rate of CVC, and reduce the incidence of CRBSI, which is worthy of clinical promotion.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

OBJECTIVE: To detect the expression of CRLF2 in bone marrow mononuclear cells from children with newly diagnosed acute lymphoblastic leukemia(ALL) and to explore its clinical significance in pediatric ALL. METHODS: A total of 218 children with newly diagnosed ALL who achieveal the complete remission and had the complete follow-up information were selected, and the expression level of CRLF2 in bone marrow mononuclear cells of these children was detected by real-time fluorescent quantitative PCR, and the significance of CRLF2 expression level in clinical prognosis of ALL children was analyzed by using statistical method. RESULTS: 28 cases in 218 children with complete data showed high expression of CRLF2. The cumulative recurrence rate in the CRLF2 high expression group was significantly higher than that in the low expression group (53.6% vs 12.6%) (P＜0.01). The predicted 5-year recurrence-free survival rate (RFS) of ALL children with CRLF2 high expression was significantly higher than that of low expression group (P＜0.01). There was no significant difference in the predicted 5-year RFS between ALL children with CRLF2 low and high expression in the standard-risk(SR) group (P＞0.05). The predicted 5-year RFS of ALL children with CRLF2 low expression was higher than that of ALL children with CRLF2 high expression in the intermediate-risk (IR) and high-risk (HR) groups. (P＜0.05). Cox analysis showed that CRLF2 high expression is an independent risk factor for the relapse of children with ALL. CONCLUSION The recurrence rate of pediatric ALL with CRLF2 high expression is high, and CRLF2 high expression is an important prognostic factor for high risk of relapse in ALL children with IR and HR. It is necessary to use CRLF2 expression as an indicator of risk stratification in pediatric ALL.
