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 clinical features of coronavirus disease 2019 (COVID-19) in patients with aplastic anemia (AA) undergoing immunosuppressive therapy (IST) . Methods: In this prospective cohort study, we collected the demographic and clinical data of patients with AA and COVID-19 from December 1, 2022, to January 31, 2023. We described the clinical features of COVID-19 among patients with AA and evaluated the effects of IST on the signs and severity of COVID-19. Results: A total of 170 patients with AA and COVID-19 were included. The common early symptoms, including fever, dizziness or headache, muscle or body aches, and sore throat, disappeared within 1-2 weeks. Approximately 25% of the patients had persistent fatigue within 2 weeks. Many patients experienced cough after an initial 1-3 days of infection, which lasted for more than 2 weeks. There were no differences in the duration of total fever episodes and maximum body temperature when patients were stratified according to whether or not they underwent IST, by IST duration, or by use of anti-lymphocyte globulin (ALG) (P>0.05). No differences were observed in the occurrence of symptoms in either the early or recovery stages when patients with AA were stratified according to whether or not they underwent IST, or by IST duration (P>0.05). However, patients who received ALG had fewer fever episodes within 1 week after infection (P=0.035) and more sore throat episodes within 2 weeks after infection (P=0.015). There were no other significant differences in clinical symptoms between patients who did and patients who did not receive ALG (P>0.05) . Conclusion: The majority of patients with AA and COVID-19 recovered within 2 weeks of noticing symptoms when treated with IST.

Objective:To evaluate the therapeutic effect and safety of microwave ablation plus curettage.Methods:Clinical data of a single group of 12 patients admitted to our hospital from June 2015 to June 2019 who underwent microwave ablation for bone metastasis were retrospectively analyzed. There were 7 males and 5 females, with an average age of 59.5±10.1 (range from 43 to 79) years old. Curettage plus bone cement after microwave ablation was performedand when the lesion involved the sacroiliac joint surface and impaired the bearing arch, the internal fixation was performed with plate and screws. 8 among the 12 patients underwent curettage, bone cement and metal internal fixation after microwave ablation. After microwave ablation, and 4 patients underwent curettage and reconstruction with bone cement alone. The patients were followed up aftersurgery. The observational indicators included: patient survival rate, local recurrence rate, perioperative complications, Operation time, intraoperative blood loss, VAS score, SF-36 score, and MSTS function score. VAS scores and SF-36 scores were recorded before surgery, 1 week after surgery and 3 months after surgery.Results:12 patients were followed up for 4-27 months, with an average follow-up time of 14.2 months and a median follow-up time of 9 months. During the follow-up, 7 patients died and 5 survived, with a 6-month survival rate of 81.8%, a 1-year survival rate of 40.9% and a 2-year survival rate of 27.3%. The mean survival time of the dying patients was 8.8 months (5-18 months), and the median survival time was 7 months. Operation time was 101±21 min and intraoperative blood loss was 295±108 ml. During the follow-up period, local recurrence rate was 8.3% (1/12), and the average postoperative time to recurrence was 4 months. There were no complications such as wound nonunion, wound infection, deep infection, vascular nerve heat injury and internal fixation failure. VAS score before surgery was 7.5 (7, 8) points, VAS score 1 week after surgery was 5 (4, 5) points, and VAS score 3 months after surgery was 5 (4, 5.75) points ( P<0.05). Preoperative SF-36 score was 23 (21, 24.75) points, 1 week after surgery SF-36 score was 47 (46, 54) points, and 3 months after surgery SF-36 score was 50.5 (47, 55.25) points ( P<0.05). 3 months after the operation, the MSTS score was 20.5 (16.25, 21.75) points, of which excellent 16.7% (2/12), good 50% (6/12), medium 16.7% (2/12), poor 16.7% (2/12), and the overall excellent and good rate was 66.7% (8/12). Conclusion:Microwave ablation plus curettage for pelvic metastasis of malignant tumor can significantly relieve local pain, rebuild limb function and improve patients' quality of life, and it`s an alternative treatment for pelvic metastases.

To construct a quality management model for the whole industry chain of compound Danshen Tablets,and quality control system for all key links in the production of compound Danshen Tablets. In this paper,with salvianolic acid B as internal reference substance,three batches of mix standards were prepared,and three sets of relative correlation factors between salvianolic acid B and other phenolic acids were calculated in parallel. Finally,the correlation factors are obtained on average. The quality transfer process was studied by optimizing the concentration of Salvia miltiorrhiza extract. The results showed that RSD among three sets of relative correlation factors ranged between 1. 7%-4. 1%,with no significant difference between the quantitative result of two methods. In addition,the quality transfer study showed that with the rise of the concentration temperature,the content of phenolic acid components changed,which had a significant effect on the salvianolic acid B at more than 80 ℃. It was suggested to rationally control the concentration temperature during the industrial production. The results of this study provide a methodology for the establishment of the quality control system for the whole industry chain of compound Danshen Tablets,and quality control methods for the improvement of the quality of medicinal materials and finished medicine products.

OBJECTIVETo investigate the hypoglycemic characteristics of hospitalized elderly patients with type 2 diabetes mellitus (T2DM).

METHODSFrom January, 2014 to December, 2015, the data of 58 565 blood measurements using a standard blood glucose monitoring system (BGMS) were collected from 1187 cases of patients with type 2 diabetes during hospitalization in the Department of Endocrinology, Guangdong General Hospital (Guangzhou, China). Stratified analyses were conducted by dividing the patients into 3 age groups, namely <45 years group (128 cases), 45-64 years group (594 cases), and ≥65 years group (465 cases). The incidence and time distribution of hypoglycemia in these patients were compared among the 3 age groups.

RESULTSThe risk of hypoglycemia increased with age. Compared with those below 45 years of age, the patients beyond or equal to 65 years had a significantly increased hypoglycemic density (0.95% vs 0.40%, P<0.001), a higher proportion of patients with hypoglycemia (28.17% vs 10.94%, P<0.001), and greater patient-days with hypoglycemia (4.48% vs 1.76%, P<0.001). In the elderly patients, hypoglycemia occurred most frequently before dawn, at which time the hypoglycemic density was 2.66% in patients ≥65 years of age, significantly higher than that in patients below 45 years (1.09%, P<0.05) and between 45 and 64 years (1.90%, P<0.05); the proportion of patients with hypoglycemia was also significantly higher in the elderly patients (14.57%) than in those below 45 years (3.77%, P<0.02) and between 45 and 64 years (9.42%, P<0.02). The proportion of patients with recurrent hypoglycemia (≥2 times) was significantly higher in patients ≥65 years (13.33%) than in younger patients (2.34% in <45 years group and 9.43% in 45-64 years group, P<0.05).

CONCLUSIONThe hypoglycemic risk in hospitalized elderly patients with T2DM is significantly higher than that in younger patients, especially before dawn and in terms of recurrent hypoglycemia. Clinicians should develop differential blood glucose monitoring and management strategies for these elderly patients to improve the clinical safety.

Objective: To explore deep vein thrombosis (DVT) occurrence in patients after right heart catheterization and the effect of anticoagulant therapy. Methods: A total of 171 consecutive patients with electrophysiological study (EPS) and/or radiofrequency catheter ablation (RFCA) in our hospital from 2015-01 to 2016-05 were enrolled. All patients had supra-ventricular tachycardia and completed a venous surgery, they were randomly divided into 2 groups: Anticoagulation group,n=87 and Non-anticoagulation group,n=84. Lower extremity vascular Doppler ultrasonography was performed at (24-48) h post-operation to compare the incidence of DVT between 2 groups. Results: There were 13/171 patients were excluded for not completing post-operative lower extremity vascular Doppler ultrasonography including 9 patients in Anticoagulation group and 4 in Non-anticoagulation group. 158 patients finished post-operative examination and follow-up study. Anticoagulation group had 7/78 (8.97%) patients suffered from DVT, Non-anticoagulation group had 41/80 (51.3%) patients suffered from DVT,P<0.001. Conclusion: The incidence of DVT was higher after right heart catheterization without anticoagulation; heparin treatment may reduce DVT occurrence in relevant patients.

BACKGROUNDOff-label application of drug-eluting stents (DES) during percutaneous coronary intervention (PCI) was not uncommon in daily practice, however DES in treating Chinese patients with complex lesion subset was under-investigated. The primary objective of the FIREMAN registry was to evaluate the long term efficacy and safety of the Firebird sirolimus-eluting stent (SES) in treating patients with complex coronary lesions. Here we report the mid-term of one-year clinical outcomes and eight-month angiographic follow-up results of FIREMAN registry.

METHODSThe FIREMAN registry was a prospective multi-center registry, which included 1029 consecutive patients undergoing PCI with Firebird SES implantation between September 2006 and July 2007 in 45 centers in China. The clinical follow-up was designed to be performed at 1, 6, 12, 18, 24, 30 and 36 months post index procedure, and non-mandatory angiographic follow-up at 8 months was planned. One hundred percent site monitoring was conducted.

RESULTSLong lesions (59.2%), multi-vessel disease (50.4%), and small vessel disease (31.6%) were mostly found in angiography. Major adverse cardiac events (MACE) occurred in 51 (5.1%) patients at 1 year clinical follow-up, including cardiac mortality in 6 (0.6%), non-fatal myocardial infarction in 11 (1.1%), and target lesion revascularization in 36 (3.5%) of the patients. Definite and probable stent thrombosis (ST) by Academic Research Consortium (ARC) definition occurred in 12 (1.36%) patients at one-year clinical follow-up. The 8-month binary restenosis rate was 5.7% in-segment and 4.3% in-stent, respectively. Late lumen loss was (0.21 ± 0.40) mm in-segment and (0.23 ± 0.36) mm in-stent, respectively. Furthermore, Cox regression analysis revealed that diabetes, small vessel diameter, and chronic total occlusion were independent predictors of ST.

CONCLUSIONSThe results showed that the Firebird SES was effective and safe in treating Chinese patients with complex coronary lesions and occurrence of ST rate at one-year clinical follow-up was acceptable, however further long-term follow-up was still necessary. (NCT00552656)

BACKGROUNDAttention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders during childhood, characterized by the core symptoms of hyperactivity, impulsivity and inattention and puts great burden on children themselves, their families and the society. Osmotic release oral system methylphenidate (OROS-MPH) is a once-daily controlled-release formulation developed to overcome some of the limitations associated with immediate-release methylphenidate (IR-MPH). It has been marketed in China since 2005 but still lacks data from large-sample clinical trials on efficacy and safety profiles. The aim of this study was to evaluate the effectiveness and safety of OROS-MPH in children aged 6 to 16 years with ADHD under naturalistic clinical setting.

METHODSThis 6-week, multi-center, prospective, open-label study enrolled 1447 ADHD children to once-daily OROS-MPH (18 mg, 36 mg or 54 mg) treatment. The effectiveness measures were parent-rated Inattention and Overactivity With Aggression (IOWA) Conners I/O and O/D subscales, physician-rated CGI-I and parent-rated global efficacy assessment scale. Blood pressure, pulse rate measurement, adverse events (AEs) and concomitant medications and treatment review were conducted by the investigator and were served as safety measures.

RESULTSA total of 1447 children with ADHD (mean age (9.52 ± 2.36) years) were enrolled in this trial. Totally 96.8% children received an OROS-MPH modal dose of 18 mg, 3.1% with 36 mg and 0.1% with 54 mg at the endpoint of study. The parent IOWA Conners I/O score at the end of week 2 showed statistically significant (P < 0.001) improvement with OROS-MPH (mean: 6.95 ± 2.71) versus the score at baseline (10.45 ± 2.72). The change in the parent IOWA Conners O/D subscale, CGI-I and parent-rated global efficacy assessment scale also supported the superior efficacy for OROS-MPH treatment. Fewer than half of 1447 patients (511(35.3%)) reported AEs, and the majority of the events reported were mild (68.2%). No serious adverse events were reported during the study.

CONCLUSIONThis open-label, naturalistic study provides further evidence of effectiveness and safety of OROS-MPH in school-aged children under routine practice.

Objective To assess the prognosis and effect on renal function of pediatric urolithiasis caused by melamine-contaminated milk powder (PUMMP) in a long-term follow-up.Methods One hundred and two of 8335 children (≤ 6-year-old) with history of consuming melamine-contaminated milk powder screened in our hospital were followed up for eighteen months after diagnosis. Urinary system ultrasonography, urinalysis, urinary microprotein profiles [microalbumin (ALBU), immunoglobulin G (IgG), and N-acetyl-β-D-glucosidase (NAG)], urinary melamine and cyanuric acid were examined in the first visit and at the end of follow-up. Results Follow-up was completed in 91 children and the stone was excreted in 82 children (90.1%).Stones less than 5 mm in diameter were most vulnerable to discharge, and stones larger than 10 mm could not be expelled without interventions. At the end of follow-up, no melamine or cyanuric acid was found in the urine samples of 74 patients. Urinalysis showed that incidences of proteinuria, microscopic hematuria and leukocyturia were 0%, 5.1% and 2.0%, which were significant different from those in the first visit (Pproteinutria=0.123, Phemnatuna=0.038 and Pleukocyhuris=0.005).Urinary microprotein profiles revealed that some children whose urinalysis was normal still presented glomerular and renal tubular injury and the abnormal rates were 8.8% and 12.1%respectively. The glomerular injury was mainly related to persistent stone, male and younger.Conclusions 90.1% of children with PUMMP passes urinary stones at the end of follow-up.Stone size is the major risk factor of discharge. No melamine or cyanuric acid is found in the urine of children. After eighteen months, glomerular and renal tubular injury is still found in some patients. Further follow-up is necessary.
