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 investigate the efficacy and safety of transcutaneous electrical acupoint stimulation(TEAS)in reducing the consumption of analgesics after total knee arthroplasty(TKA).Methods Totally 124 patients undergoing unilateral TKA were included and divided into an intervention group and a control group according to random number table method,with 62 cases in each group.Both groups received routine postoperative analgesic protocols,with the intervention group additionally receiving TEAS treatment,30 min per time,twice a day.The additional doses of intravenous patient-controlled analgesia pumps and opioid analgesic consumption in two groups of patients after surgery were analyzed,as well as the adverse events and laboratory test results(WBC,PLT,SCr,BUN,ALT and AST)in both groups.Results The number of additional doses in the intervention group with the patient-controlled analgesia pump and the consumption of opioid analgesic were both lower than those in the control group(P<0.05);the incidence of postoperative nausea symptoms in the intervention group was lower than that in the control group,while other adverse reactions showed no significant difference(P>0.05).There was no significant difference in laboratory test results(WBC,PLT,SCr,BUN,ALT and AST)between the two groups on the day before surgery and on the 1st and 7th days after surgery(P>0.05).Conclusion TEAS can reduce the consumption of analgesics after TKA,decrease some adverse reactions associated with the use of analgesics,and has good safety.

Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.

Objective:To investigate the clinical efficacy and safety of Pseudomonas aeruginosa injection in preventing reurrent urinary tract infection in women. Methods:This was a multicenter, randomized, open, positive-controlled, non-inferiority trial involving female patients with recurrent urinary tract infections (rUTIs) who were admitted to 11 medical centers in China. Inclusion criteria: ①Aged 18-70 years, with verifiable clinical data showing at least 3 episodes of acute UTIs within 1 year and at least 2 episodes within 6 months, and cured by antimicrobial therapy; ② At the time of enrollment, the patients had no obvious symptoms of urinary tract irritation, normal white blood cell count in midstream urine routine (within the normal range of laboratory standards of each unit) or ≤3HP by centrifuge microscopy, negative leucocyte esterase and nitrite, and negative urine culture; ③No abnormal urinary anatomic function (such as urinary obstruction, calculus or congenital urinary malformation) and residual urine volume ≤50 ml were detected by B-ultrasound of urinary system; ④Informed consent signed by the person or agent; ⑤Clear consciousness, able to answer questions independently, according to the requirements of the test plan to complete the research questionnaire. Exclusion criteria: ①Patients allergic to the above drugs; ②Any complex signs of urinary tract infection or pyelonephritis (manifested as low back pain, fever ≥37.3℃, systemic symptoms); ③Drugs affecting immune function were used within 7 days before randomization; ④Patients with basic diseases of urinary system such as obstruction, calculus, urinary stenosis, vesicoureteral reflux or other functional abnormalities, urine diversion, indwelling catheter or stent tube or intermittent catheterization; ⑤Combined with or existing systemic lupus erythematosus, AIDS and other diseases that can lead to systemic immune function abnormalities; ⑥Patients who are known or suspected to be pregnant, breastfeeding, or planning a pregnancy within 3 months of stopping the drug; ⑦Patients with malignant tumors and mental patients; ⑧Persons who have received any other investigational drug treatment or participated in another interventional clinical trial within 4 weeks prior to screening; ⑨Failure to comply with the trial protocol or other conditions deemed unsuitable for enrollment by the investigator. Patients were randomly divided into 2 groups. The experimental group was given Pseudomonas aeruginosa injection for 5 times, 0.5 ml for the first time, and 1 ml/ time per week for the following 4 weeks. The control group was given fosfomycin aminotriol 3g orally, once every 10 days, for 9 consecutive times. The patients were followed up for 6 to 8 months, during which urinary tract symptoms developed and routine urine tests showed abnormally elevated white blood cells, which was defined as recurrent UTIs. Urine routine, liver and kidney function, and urinary secretory immunoglobulin A(SIgA) were reviewed 0-2 days (V2) after the 5th administration of the experimental group and the 4th administration of the control group. Urine routine and urine SIgA were reviewed at (90±10) d (V3) and (180±10) d (V4) after treatment. At (270±10) d (V5) after treatment, the recurrence (re-infection caused by the same species of bacteria) or re-infection (re-infection caused by non-same species of bacteria) of the two groups were compared, and non-inferiority analysis was performed, and the non-inferiority threshold was set at 0.2. Results:From March 2021 to May 2022, a total of 152 rUTIs patients were enrolled in this study, including 80 patients in the experimental group, 71 patients in the intention-to-analysis set (ITT) and 66 patients in the protocol analysis set (PPS). In the control group, 72 cases met ITT in 69 cases and PPS in 67 cases. There were no significant differences in age, body mass index, marital status, duration of urinary tract infection, history of diabetes, history of previous major surgery, history of infection, and urinary SIgA between the two groups (all P>0.05). The recurrence rates of the experimental group and the control group at V5 time point were 44.78% (30/67) and 42.65% (29/68), respectively ( P=0.803) (ITT data set analysis results showed that the difference in recurrence rates between the two groups was 0.0213(95% CI-0.1460-0.1886, P=0.0048). PPS data set analysis showed that the difference of recurrence rate between the two groups was -0.0021(95%CI -0.1711-0.1670, P=0.0109), and the recurrence rate of the experimental group was not worse than that of the control group. At V2 time points, there were no significant differences in liver and kidney function indexes between test group and control group ( P>0.05). At V2 to V4 time points, urinary SIgA of test group and control group were 0.90 (0.37, 2.89) mg/L and 1.32 (0.34, 3.08) mg/L, 1.54 (0.44, 3.23) mg/L and 1.71 (0.27, 2.92) mg/L, 1.11 (0.65, 3.42) mg/L and 2.18 (0.43, 3.26) mg/L, there was no statistical significance ( P>0.05). The incidence of adverse events in the experimental group was 30.0% (24/80), including 14 cases of redness, pain and discomfort at the injection site, 5 cases of fever, 2 cases of allergic rash, and 1 case of urticaria, headache and constipation each. The incidence of adverse events in the control group was 5.6% (4/72), all of which were diarrhea, and the difference between the two groups was statistically significant ( P<0.01). No life-threatening serious adverse events occurred in both groups, and all adverse events were self-healing without additional intervention. Conclusions:Compared with fosfomycin aminotriol, Pseudomonas aeruginosa injection has the same clinical effect in preventing rUTI and has good safety.
