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.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background::China is one of the countries with the largest burden of gastrointestinal and liver diseases (GILD) in the world. The GILD constitutes various causes of mortality and disability. The study aimed to investigate the trend of GILD in China using the Global Burden of Diseases Study 2019 (GBD 2019) data resources from 1990 to 2019.Methods::The data on the age-standardized mortality rates (ASMR) and disability-adjusted life years (DALYs) for GILD in China from 1990 to 2019 were collected from the GBD 2019 data resources. Furthermore, the ranking of the main causes of deaths and DALYs, as well as the trends of ASMR, DALYs, years of life lost (YLLs), and years of life lost due to disability (YLDs) per 1,000,000 in GILD were reported.Results::The ASMR and DALYs for stomach cancer, liver cancer, and esophageal cancer, which ranked top three among the GILDs from 1990 to 2019, were gradually decreasing. Significant decreases in the ASMR and DALYs were found in diarrheal diseases and acute hepatitis (A, E, and C). However, noteworthy increases were found in those of colon and rectum cancer (CRC) and pancreatic cancer. Trend of DALYs, mortality, and YLLs rates for most of GILD were decreasing from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trend. The DALYs, mortality and YLLs of most GILD diseases showed decreasing trends from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trends.Conclusions::The result of the GBD 2019 showed that the rates of most GILDs decreased in China; however, gastrointestinal and liver cancer, such as stomach cancer still held the top ranking. Furthermore, the shift from infectious diseases to non-communicable causes among GILD burden is occurring.

OBJECTIVE: To explore characteristics of contrast-enhanced ultrasound (CEUS) images features and diagnostic value of rotator cuff tear subtypes. METHODS: From January 2019 to March 2022, percutaneous ultrasound-guided subacromial bursography (PUSB) with persutaneous ultrasound-guide tendon lesionography (PUTL) was performed on 114 patients with suspected rotator cuff injury were evaluated, including 54 males and 60 females ranged in age from 35 to 75 years old with an average of (58.8±8.7 ) years old;76 patients on the right side and 38 patients on the left side;the course of disease ranged from 0.13 to 111 months with an average of (10.2±9.8) months. GE LOGIQ E9 color doppler ultrasound diagnostic high frequency(6 to 12 MHz) was used to CEUS Using arthroscopy as gold standard, receiver operating characteristic (ROC) curve was used to evaluate diagnostic efficacy of US, MRI and CEUS for rotator cuff injury, also sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated. RESULTS: The sensitivity of US in diagnosing full-thickness tears was 72.1%, specificity was 93.0%, and accuracy was 85.1%. The sensitivity, specificity and accuracy of MRI diagnosis of full-thickness tear were 90.9%, 92.6% and 92.1% respectively. The sensitivity, specificity and accuracy of CEUS in diagnosis of full-thickness tear were 100%. The sensitivity, specificity and accuracy of US in the diagnosis of partial tear were 85.7%, 77.2% and 79.8% respectively. The sensitivity, specificity and accuracy of MRI diagnosis of partial tear were 83.7%, 81.7% and 82.5% respectively. The sensitivity, specificity and accuracy of CEUS in diagnosis of partial tear were 95.7%, 92.6% and 93.9% respectively. There were significant differences in diagnosis results of US, MRI and CEUS for rotator cuff bursa tear (P<0.001). Kapp test showed good consistency between CEUS and arthroscopy in diagnosing rotator cuff tear subtypes (full-thickness and partial tears). CONCLUSION Using PUSB/PUTL to observe distribution of contrast media in bursa, tendon and joint cavity to evaluate the type of rotator cuff tear, its diagnostic performance is significantly better than US and MRI. Therefore, percutaneous contrast-enhanced ultrasound can be a reliable method for diagnosing subtypes of rotator cuff tears.

ObjectiveTo investigate inhibitory effect of extracts from Veronica peregrina （EVP） on the osteoclastic bone metastasis induced by breast cancer cells. MethodBone metastasis model was established by injection of MDA-MB-231 cells， a human breast cancer cell line， into the left ventricle of BALB/c nude mice. The expression of human cytokeratin-19 （Ck-19） gene in mouse bone marrow was determined by nested polymerase chain reaction（PCR） to assess the bone metastasis of MDA-MB-231 cells. To assess the effects of EVP on the activation of bone marrow macrophages （BMMs）， we counted the multinuclear cells and measured the secretion of Cathepsin K. Western blot was adopted to assess the effects of EVP on receptor activator of nuclear factor-κB （RANK）， Runt-related transcription factor 2 （ Runx2 ）， phosphorylated Runx2 （p-Runx2）， and matrix metalloproteinase-9 （MMP-9） in BMMs. Gelatin zymography was employed to determine the activities of matrix metalloproteinases （MMPs）. ResultCompared with that in the blank group， Ck-19 expression was down-regulated in EVP groups （P<0.05）. The multinucleated cells increased when the BMMs were induced by soluble receptor activator of nuclear factor-κB ligand （sRANKL）， which was inhibited by EVP （P<0.05）. The level of cathepsin K in the supernatant of sRANKL group increased compared with that of the blank group， while EVP groups had lower cathepsin K levels than sRANKL group （P<0.05）. Compared with the blank group， the sRANKL group showed up-regulated RANK expression， Runx2 phosphorylation， and MMP-9 expression （P<0.05）， while the expression levels of RANK， p-Runx2， and MMP-9 were down-regulated when the cells were incubated with EVP （P<0.05）. Furthermore， exposure of BMMs to sRANKL resulted in an increase in gelatin hydrolyzation compared with the blank group （P<0.01）， which， however， was reversed in EVP groups （P<0.05）. ConclusionEVP significantly inhibits bone marrow metastasis of MDA-MB-231 cells， which may be associated with the suppression of osteoclast activation by inhibiting Runx2 phosphorylation.

OBJECTIVE: To investigate the effectiveness and safety of low concentration dithiothreitol (DTT) in removing the interference of monoclonal anti-CD38 on transfusion compatibility testing, and develop a reasonable clinical transfusion strategy. METHODS: The blood type, direct antiglobulin testing (DAT) and antibody screening were tested according to standard methods. Antibody screening cells and donor's red blood cells were treated by DTT 0.2, 0.1, 0.05, 0.02, 0.01 and 0.005 mol/L, and antibody screening and cross-matching of serums after monoclonal anti-CD38 treatment were performed by anti-human globulin card. RESULTS: The 0.01 mol/L DTT at 37℃ for 30 minutes could remove the effect of monoclonal anti-CD38 on antibody screening and cross-matching, meanwhile retain their effectiveness in detecting anti-K, anti-LW, anti-JMH, anti-Lu^b, anti-e, anti-Di^a and anti-Jk^a alloantibodies. All the 10 patients had no acute or delayed haemolytic transfusion reactions and their routine blood tests showed that the red blood cells transfusion was effective. CONCLUSION The 0.01 mol/L DTT is a safe and effective method for removing the interference of monoclonal anti-CD38 with transfusion compatibility testing, while retaining the ability to detect most alloantibodies.

Objective:To determine the epidemiological characteristics and incidence trends of sexually transmitted diseases （STD） in Mengla County of Yunnan Province， and provide evidence for future prevention and control of STD. Methods:STD case information from 2005 to 2017 was extracted from the National Notifiable Infectious Disease Report Information System. Data were collected by year and disease type，and the incidence rate， epidemic characteristics and suspicious contact history of STD were statistically analyzed. Results:A total of 1 251 STD cases were reported in Mengla county from 2005 to 2017， including 490 gonorrhea， 483 syphilis， 216 condyloma acuminatum， 16 genital chlamydial infection and 46 genital herpes. The average annual incidence of STD was 35.57/100 000. The majority of STD cases were 20-29 years old （n=541，43.25%）， married （n=603，48.20%）， Han people （n=638，50.10%）， with education of middle school （n=536，42.85%）， and occupation of farmers （n=702， 56.12%）. The 42.61% of STD cases had non-marital sexual contact history， in which the proportion was significantly higher among male （55.05%） than female （28.98%）. In addition， the proportion of non-marital sex among STD cases increased gradually by year and significantly differed. Conclusion:The epidemic status of STD in Mengla county is relatively low. However， STD incidence increased gradually by year， which warrants more and specific measures on the STD control and prevention.
