Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To explore the reliability of the reagent burstbead for field blood transfusion compatibility testing by applying it to bloodtype detection,antibody screening and cross matching tests and conduting parallel contrast with the existing arrays.Methods A field treatment shelter was used as the testing site to simulate the scene of emergency blood transfusion for the wounded under the conditions of field blood station,and 1 358 pieces of blood samples sent to some hospital for examination before transfusion were considered as the objects.Parallel contrast tests were carried out between the reagent burstbead method and the tube method for bloodtype detection and between the reagent burstbead method and the manual polybrene method for antibody screening and cross matching.The reagent burstbead method was compared with other methods in terms of the coin-cidence rate of the bloodtype detection results,the detection rate of positive samples for antibody screening and crossmatch incompatibility.Results The reagent burstbead method and the tube method had high consistency when used for bloodtype detection,with the coincidence rate being 100％.During antibody screening and cross matching tests,the reagent burstbead method found 5 cases of antibody-positive samples leading to major crossmatch incompatibility(positive rate being 0.37％),the manual polybrene method detected 2 cases of irregular antibody-positive samples(positive rate being 0.15％),and the two methods both identified 3 cases of minor crossmatch incompatibility.Conclusion The reagent burstbead has high accuracy and reliability when applied to bloodtype detection,antibody screening and cross matching tests,and thus can be used for blood transfusion compatibility testing in field conditions.[Chinese Medical Equipment Journal,2025,46(2):39-42]

Hypokalemia,a common clinical electrolyte disorder,can affect multiple systems and can be life-threatening in severe cases.Identifying the cause of hypokalemia is crucial for its prevention and treatment.However,the etiology of hypokalemia is complex and often requires detailed differential diagnosis.This article reports a rare clinical case of hypokalemia caused by long-term excessive consumption of strong tea and discusses its pathogenesis.The aim is to raise clinical awareness and understanding of the etiology of such cases of hypokalemia and reduce misdiagnosis and missed diagnosis.

Objective:To observe the early efficacy of intense pulsed light(IPL)combined with non-ablative fractional laser(NAFL)in preventing postoperative pathological scar formation and intervention of inflammatory factors.Methods:93 patients with postoperative pathological scar formation who were admitted to our hospital from March 2022 to September 2024 were selected,they were divided into control group A(silicone gel treatment,n=31),control group B(NAFL on the basis of control group A,n=31)and study group(IPL on the basis of control group B,n=31)using the random number table method.The clinical efficacy,simple quality of life scale(SF-36),vancouver scar scale(VSS),inflammatory factors[interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)],and adverse reactions among three groups were compared.Results:The clinical total effective rate in the study group were higher than those in the control group A and control group B(P＜0.05).SF-36 increased sequentially and VSS decreased sequentially in control group A,control group B,and study group after treatment(P＜0.05).CRP,IL-6,and TNF-α decreased sequentially in control group A,control group B,and study group after treatment(P＜0.05).There was no significant difference in the incidence of adverse reactions among the three groups(P＞0.05).Conclusion:IPL combined with NAFL in preventing postoperative pathological scar formation,can effectively reduce scar formation,reduce inflammatory factors levels,improve patients' quality of life,and be safe and reliable.

Objective To establish a risk prediction model of continuous renal replacement therapy(CRRT)withdrawal failure in patients with infectious shock complicating acute kidney injury(AKI)based on the decision tree algorithm,and to explore the influencing factors of CRRT withdrawal failure in patients with infectious shock complicating AKI.Methods 220 patients with infectious shock complicating AKI admitted to our hospital from May 2020 to May 2023 were retrospectively analyzed,and divided into success group and failure group according to the success or failure of the withdrawal,univariate and multivariate Logistic regression analysis were used to screen risk factors of CRRT withdrawal failure in patients with septic shock complicated with AKI,C-reactive protein/albumin(CRP/ALB)at admission and sepsis-related organ failure assessment(SOFA)score at withdrawal,acute physiology and chronic health evaluation(APACHE Ⅱ)score,N-terminal B-type natriuretic peptide(NT-proBNP)level at the beginning of CRRT,mean arterial pressure(MAP)grading,urine volume after withdrawal,and serum creatinine(Scr)level after withdrawal were taken into constructing a decision tree model and validating the model efficacy.Results In this study,there were 41.82％of patients failed to withdrawal.Combination of univariate and multivariate Logistic regression analysis showed that SOFA score at withdrawal,APACHE Ⅱ scores,urine volume after withdrawal,Scr level after withdrawal,NT-proBNP at the beginning of CRRT,and MAP grading,CRP/ALB at the time of admission were an independent risk factor for CRRT withdrawal failure in patients with septic shock complicated with AKI(P＜0.05).The results showed that the higher CRP/ALB was the most important influencing factor on the failure of CRRT evacuation in patients with infectious shock complicating AKI,and the area under the receiver operating characteristic curve was 0.965.Conclusion The decision tree model constructed by CRP/ALB at admission,SOFA score at withdrawal,urine volume after withdrawal,Scr level after withdrawal,APACHE Ⅱ score,and MAP grading has a better predictive efficacy of CRRT withdrawal failure in patients with infectious shock complicating AKI,which is a guideline for patients'prognostic assessment.
