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.

The incidence of aortic valve disease gradually increases with age,and has become an upward trend in recent years.Transcatheter aortic valve replacement(TAVR)has become the first-line treatment for aortic stenosis(AS)due to minimal surgical trauma and fast postoperative recovery.But TAVR is a complex and high-risk technology,and the operation requires multidisciplinary collaboration and a comprehensive nursing team.Nursing care is crucial during the perioperative period of TAVR.This article aims to provide a comprehensive review of perioperative nursing for TAVR patients,based on the latest research progress both domestically and internationally,in order to enhance the care of TAVR patients during the perioperative period,especially for postoperative complications.

OBJECTIVE: To carry out amniocyte karyotyping analysis and chromosomal microarray analysis (CMA) for women with anomalies revealed by fetal echocardiography. METHODS: From January 2019 to December 2021, genetic testing was carried out for 205 fetuses including 97 with soft marker anomalies and 108 with structural heart abnormalities. Among these, 138 only had abnormal fetal echocardiography, whilst 38 and 29 were complicated with extracardiac soft marker anomalies and extracardiac structural malformation, respectively. RESULTS: No significant difference was detected in the detection rate of genetic anomalies between fetuses with heart-related soft markers and those with abnormal heart structures (P > 0.05). Compared with those with abnormal fetal echocardiography alone, the detection rates of chromosomal aneuploidies in those with abnormal extracardiac soft markers or abnormal extracardiac structures were significantly higher (P < 0.05). Twenty-eight chromosomal aneuploidies (including a rare mosaicism), 2 balanced translocations and 1 supernumerary marker chromosome were detected by karyotyping analysis. Twenty-seven aneuploidies, 19 copy number variations (CNVs) and 1 uniparental disomy were detected by CMA. CONCLUSION Prenatal diagnosis has attached great importance to the suggestive role of fetal heart-related soft markers, and chromosomal aneuploidies are more common among fetuses with abnormal extracardiac soft markers and extracardiac structural abnormalities. Chromosomal Karyotyping is useful for the detection of balanced translocations and mosaicisms. CMA is helpful for the detection of CNVs. Identification of the genetic causes can facilitate genetic counseling for the affected couples.

Objective To compare the effects of different doses of sufentanil on theα1?band of quantitative pharmaco?electroencephalography (QPEEG)during the induction of general anesthesia by tracheal intubation(TI). Methods Forty selected patients under general anesthesia were randomly divided into two groups,with 20 patients per group. Patients in group Ⅰ were administered 0.2μg/kg sufentanil,whereas patients in group Ⅱ were administered 0.3μg/kg sufentanil. Subsequently,the patients were administered 2 mg/kg propofol and 0.15 mg/kg cisatracurium. HR,MAP,and QPEEG were recorded before induction(T0),after induction(T1),and after insertion of the cannula(T2). Using the method of power spectrum analysis,theα1?band power percentage of QPEEG was calculated. Results In comparison with T0,the values of HR,MAP,andα1?band power percentage in most areas of the brain were both decreased at T1(P<0.05). Furthermore,in comparison with T1,the parameters were increased in group Ⅰ at T2(P<0.05),but no significant changes were observed in group Ⅱ (P>0.05). Conclusion The administration of 0.3μg/kg sufentanil during anesthesia induction can effectively depress the cardiovascular response to TI and stabilize theα1?band power per?centage. This suggests that theα1?band power percentage of QPEEG can be an effective means to monitor the depth of sedation.

Objective To investigate the effects of transcutaneous electrical acupoint stimulation (TEAS) on electroencephalography (EEG) in piglets anesthetized with sevoflurane.Methods Twelve piglets,aged three to seven days,weighing 1.5 to 3.5 kg,were randomly divided into 2 groups:TEAS (group T,n =6) and control (group C,n =6).Group T received continuous TEAS at points baihui and tianmen for 30 minutes.Anesthesia was induced with 8.0％ sevoflurane over 3 minutes and maintained with 3.5％ sevoflurane in both groups.The changes were observed on EEG.Results The heart rates (HR) at intubation and extubation were lower in group T than group C (P ＜ 0.05).Compared with group C,the EEG spike frequency was lower in group T during anesthesia induction and maintenance (P ＜ 0.05).Conclusion Sevoflurane can induce EEG spikes in piglets,which can be reduced by TEAS.

Objective To study the etiology, clinical and pathological characteristics, therapy and prognosis of acute renal failure (ARF). Methods The literature of 80 treated children with ARF from 1988. 1 to 2003.10 was reviewed. Results Sixty three cases (78.8%)suffered from mtrarenal ARF;47 glomerulonephritls (58. 8%); 15(18. 8%)prerenal ARF;2(2 5%)postrenal obstructive ARF. Twenty three cases with renal biopsy,9(39. 1%)MsPGN;4 (17. 4% ) MPGN; 4 (17. 4%) crescentic glomerulonephntis; 3 (13% ) endocapillary glomerulonephritls;2(8 7% )proliferative and sclerosing glomerulonephritis; 1(1. 3% )minimal changes. According to the different etiologic and pathological characteristics,different therapies were applied,infusion,oral prednisone ,and intravenous pulses of methylprednisone and cyclosphosphamide ,dialysis, or diuretic therapy and lowering blood. Thirty one (38. 8% )cases recov-ered;27(33 8% )cases improved; 10( 12.5% ) cases gave up treatments;21 (26 3% )died. The mortality of ARF from 1996 to 2003 was significantly lower than that from 1988 to 1995(x2 = 7.85 P
