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 understand the current knowledge, attitude, and practice (KAP) on influenza and influenza vaccine among pregnant women in Suzhou and to analyze its influencing factors to provide technical support data for public health strategies for promoting influenza vaccination in pregnant women.Methods:A questionnaire was designed, and a stratified sampling method was used to conduct a face-to-face survey among pregnant women at different stages of pregnancy who received antenatal examinations at different levels of medical institutions in Suzhou, Jiangsu Province, in 2023. KAP status and influencing factors were analyzed by χ2 test and logistic regression analysis. Results:A total of 2 195 valid questionnaires were collected in this survey. The M( Q1, Q3) of knowledge about influenza and influenza vaccine among pregnant women in Suzhou was 7.60 (5.23, 9.80) points, and the score range was 0.20-14.71 points, the passing rate was 34.12%, the awareness rate of influenza vaccine was 57.45%, and the vaccination rate of influenza vaccine was 1.91% within one year before the survey. The willingness to receive influenza vaccine during pregnancy was only 3.57%. Multivariate analysis of influenza and influenza vaccine-related knowledge scores showed that the passing rate was positively correlated with education level and gestational age. In contrast, family income was negatively correlated with living in rural areas, working as migrant workers, and having no medical insurance. Multivariate analysis of vaccination intention showed that decreased effectiveness of influenza vaccine and increased adverse reactions decreased vaccination intention during pregnancy. Conclusions:The pregnant women in Suzhou pay more attention to influenza, and vaccination rates and intentions are generally low. Pregnant women with early and second trimester of pregnancy, low education, living in rural areas, working as migrant workers, and not purchasing medical insurance are the key groups to popularize the knowledge about influenza and influenza vaccine.

Discordance, such as overlap, repetition and inconsistent, of standards is one of the major problems in current standardization affair in China. Therefore, improving the unity and authority of standards through reduction of overlap, repetition and inconsistency has become the main goal of deepening standardization reform in China. This paper summarizes the discordance in public health standards in China, analyzes the major reasons and provides specific strategic suggestions through case analysis of public health standards in the ways of comparisons of same kind standards of other deparments and standards in administration documents and guidelines or technical specifications of academic associations or societies.

Objective To investigate the effect of 5-hydroxytryptamine serotonin receptor-1A (5-HT1 A) agonists on micturition dysfunction in rats with chronic spinal cord injury (SCI).Methods Female SD rats weighing 175 -200 g were used.Seven of the rats were modified for a spinal cord injury model (transsection at T10).Eight weeks later,control rats and SCI rats were tested.Rats were anesthetized with urethane ( 1.3 g/kg ).A polyethylene (PE) -50 catheter was placed in the left jugular vein for intravenous drug administration.A PE-90 catheter was inserted through the bladder dome,and the other end of the bladder catheter was connected to a syringe pump for continuous infusion of saline and to a pressure transducer for intravesical pressure monitor.Dose-response curves for 8-OH-DPAT were followed by the WAY-100635 test.The capacity,residual volume,micturition volume,and EUS-EMG were measured.Results With an increasing dose of 8-OH-DPAT,the capacity of the bladder decreased from 33.2 ± 8.3 ml to 22.8 ± 2.4 ml.The micturition volume was increased from 0.14 ± 0.08 ml to 0.38 ± 0.09 ml.The residual volume decreased from 3.68 ± 1.36 ml to 1.84 ± 0.21 ml,and peak intravesical pressure changed from 27.1 ± 3.6 mm Hg to 22.8 ± 2.4 mm Hg.Control rats showed little significant change in the cystometric variable.Effects of 8-OH-DPAT were reversed by WAY-100635.That 8-OH-DPAT induced phasic relaxation occured in spinal cord-injured rats but the control group showed no significant change.ConclusionsThe 5-HTIA/7 receptor agonist 8-OH-DPAT may induce periodic EUS relaxation during voiding in urethane-anesthetized chronic spinal cordinjured rats.And this could result in an increase in micturition volume,a decrease in bladder capacity,and thus an increase in voiding efficiency.

Objective To observe the efficacy of WS-frequency spectrum in treating second degree burn wounds. Methods 350 cases of second degree burn were treated in the whole couse with WS-frequency spectrum in association with systemic treatment including anti-shock,anti-infection and expecant treatment. Results All the patiens healed,only 23 cases with deep burn area over 20% TBSA resulted in superficial pigmentation and scar formation without dysfuntion. Conclusion WS-frequency spectrum is a good remedy for treating second degree burn. This method is easy and simple to apply and has very good efficacy.

Objective To construct recombinant human Bcl-2 adenoviral vector. Methods Sense human Bcl-2 cDNA fragment from plasimid pcDNA3 1/bcl-2 was cloned into adenovirus shuttle vector pAdCMV. pAdCMV/bcl-2 and plasmid pJM17 were cotransfected into 293 cells with lipofectamine 2000. Replication defective adenovirus was reproduced and purified. Adenoviral virus DNA was detected with polymerase chain reaction(PCR), and plaque assay was performed to determine the titer of virus. Results Recombinant adenovirus containing bcl-2 target gene was obtained. The titer of virus was 2 0?10 10 pfu/ml. Conclusion High titer of adenovirus containing target gene was successfully obtained by recombinant adenovirus vector.
