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 relationship between the expression levels of thyroid transcription factor-1(TTF-1)and Galectin-3 in differentiated thyroid carcinoma(DTC)tissues and clinical manifestations and prognosis of patients.Methods A total of 76 DTC patients admitted to the hospital from January 1,2017 to May 30,2020 were selected as the study objects.Cancer tissue specimens obtained during surgery were in-cluded in the DTC group(n=76),and corresponding paracancer tissue specimens were included in the para-cancer group(n=76).The expressions of TTF-1 and Galectin-3 in DTC group and paracancer group were de-tected by immunohistochemistry,and the relationship between the expression levels of TTF-1 and Galectin-3 and the clinicopathological characteristics of DTC patients was analyzed.Multivariate Cox regression analysis was used to investigate the prognostic factors of DTC patients.Results The positive expression rates of TTF-1 and Galectin-3 in DTC group were higher than those in paracancer group,and the difference was statistically significant(P＜0.05).The TTF-1 positive expression rate and Galectin-3 positive expression rate in DTC pa-tients with TNM stage Ⅲ to Ⅳ,low differentiation,tissue type of papillary thyroid carcinoma and lymph node metastasis were higher than those in DTC patients with TNM stage Ⅰ to Ⅱ,medium/high differentiation,tis-sue type of thyroid follicular carcinoma and no lymph node metastasis.The difference was statistically signifi-cant(P＜0.05).The 3-year overall survival rate of TTF-1 negative and Galectin-3 negative DTC patients was higher than that of TTF-1 positive and Galectin-3 positive DTC patients,and the difference was statistically significant(P＜0.05).Multivariate Cox regression analysis showed that lymph node metastasis,positive TTF-1 and positive Galectin-3 were prognostic factors in DTC patients(P＜0.05).Conclusion TTF-1 and Galectin-3 are related to TNM stage,differentiation degree,tissue type,lymph node metastasis and 3-year sur-vival rate of DTC patients,and have important reference value for the diagnosis and prognosis evaluation of DTC patients.

This study was aimed at understanding the detection rate,drug resistance characteristics,virulence characteris-tics,multi-locus sequence typing,and other molecular epidemic and pathogenic characteristics of Campylobacter jejuni and Campylobacter coli in children in Guangdong Province from 2020 to 2022.Anal swabs or stool samples of suspected infection cases in children from 2020 to 2022 were collected from two hospitals in Guangzhou,Guangdong Province.Campylobacter was isolated and cultured through the filtration method,and identified with a microbial mass spectrometry system;antibiotic resist-ance was analyzed with the agar dilution method;bacterial genome nucleic acids were extracted,and whole-genome sequencing was conducted;and drug resistance genes,virulence genes,multi-locus sequence typing,and phylogenetic analysis based on whole-genome single nucleotide polymorphisms were analyzed from whole-genome sequencing results.First,53 strains of Campy-lobacter were detected through continuous routine monitoring in this study,with a positive detection rate of 2.94％.Among them,Campylobacter jejuni accounted for 81.13％(43/53)and Campylobacter coli accounted for 18.87％(10/53).In addition,16 strains of Campylobacter were screened through multi-pathogen surveillance,including 11 strains of Campylobacter jejuni and 5 strains of Campylobacter coli.Drug resistance ex-periments and whole genome sequencing were conducted on 46 Campylobacter isolates,including 33 isolates of Campylobacter jejuni and 13 isolates of Campylobacter coli.The resistance rate of Campylobacter to erythromycin,a widely used clinical treatment,was21.73％(10/46);that to tetracycline was 80.43％(37/46);those to the quinolone antibiotics nalidixic acid and ciprofloxacin were 76.08％(35/46)and 71.73％(33/46)respectively;and that to chloramphenicol was lowest,at 2.17％(1/46).The drug resistance rate was generally higher for Campylobacter coli than Campylobacter jejuni,and the differences in the indicators of erythromycin,gentamicin,streptomycin,telithromycin,and clindamycin were statistically significant.A total of 30 isolates of multidrug-resistant Campylobacter were detected,including nine multidrug-resistant phenotypes.Whole-ge-nome sequence analysis indicated that 46 Campylobacter isolates carried antibiotic resistance genes for antibiotics such as quino-lones,tetracyclines,β-lactams,and aminoglycosides,and carried 128 virulence factor genes in five categories.All 46 isolates of Campylobacter were identified as 35 ST type through MLST typing,and phylogenetic analysis indicated no obvious dominant ST type.Campylobacter coli had more SNPs than Campylobacter jejuni.In conclusion,the positive detection rate of Campy-lobacter in Guangzhou City,Guangdong Province stabilized from 2020 to 2022,and the detection rate of Campylobacter jejuni was higher than that of Campylobacter coli.Campylobacter isolates were resistant to tetracyclines and quinolone,and showed a wide spectrum of multi-drug resistance,which was relatively severe among Campylobacter coli.Resistance genes and drug-resistant phenotypes were correlated and had predictive significance.The virulence genes of Campylobacter jejuni were more a-bundant than those of Campylobacter coli,possibly because of the higher detection rate and pathogenicity of Campylobacter jejuni.The phylogenetic tree showed clear branches with high genetic diversity and no clearly dominant clonal group.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Objective To explore the protective mechanism of RNA binding protein LIN28 on diabetic nephropathy(DN).Methods LIN28 was overexpressed or knocked down by adenovirus in HEK 293T cells.The gene and functional signaling pathway significantly changed after overexpression of LIN28 were obtained through RNA Seq transcriptome sequencing and bioinformatics analysis.HEK 293T cells were divided into the Control group,the Treatment group,the Adv-LIN28-OE+D-ribose group and the Adv-LIN28-NC+D-ribose group in in vitro LIN28 overexpression studies.And HEK 293T cells were divided into the Control group,the Treatment group,the Adv-shRNA LIN28+D-ribose group and the Adv-shRNA NT+D-ribose group in in vitro LIN28 knockdown studies.ELISA was used to detect the levels of human advanced glycation end products(AGEs)of cells supernatants in the above groups.Western blot was used to detect the expression levels of RAGE,NF-κB and MMP-2 of cells in the above groups.Results The results of RNA-Seq transcriptome sequencing,GO analysis and KEGG analysis showed that overexpression of LIN28 resulted in a significant down-regulation of AGE-RAGE signaling pathway in HEK 293T cells(P<0.05).The results of ELISA showed that compared with the Control group,the cell in the Treatment group produced a large amount of AGEs(P<0.05);compared with the Treatment group,the AGEs level of cells in the Adv-LIN28-OE+D-ribose group was significantly decreased(P<0.05),while the AGEs level of cells in the Adv-shRNA LIN28+D-ribose group was increased(P>0.05).The results of Western blot showed that compared with the Control group,the expression levels of RAGE,NF-κB and MMP-2 of cells in the Treatment group were significantly increased(P<0.05);compared with the Treatment group,the expression levels of RAGE,NF-κB and MMP-2 of cells in the Adv-LIN28-OE+D-ribose group were significantly decreased(P<0.05),while the expression levels of RAGE,NF-κB and MMP-2 of cells in the Adv-shRNA LIN28+D-ribose group were significantly increased(P>0.05).Conclusion Overexpression of LIN28 by adenovirus at the cellular level in vitro can lead to significant differential expression of thousands of genes.In particular,it can inhibit the diabetes and complications-related AGE-RAGE signaling pathway,which is critical in the progression of DN disease,and play a role in protecting DN.

Objective: To examine the clinical effect of minimally invasive duodenum preserving pancreatic head resection(DPPHR) for benign and pre-malignant lesions of pancreatic head. Methods: The clinical data of patients with diagnosis of benign or pre-malignant pancreatic head tumor were retrospectively collected and analyzed,all of them underwent laparoscopic or robotic DPPHR between October 2015 and September 2021 at Division of Gastrointestinal and Pancreatic surgery,Zhejiang Provincial People's Hospital. Thirty-three patients were enrolled with 10 males and 23 females. The age(M(IQR)) was 54(32) years old(range: 11 to 77 years old) and the body mass index was 21.9(2.9)kg/m²(range: 18.1 to 30.1 kg/m²). The presenting symptoms included abdominal pain(n=12), Whipple triad(n=2), and asymptomatic(n=19). There were 7 patients with hypertension and 1 patient with diabetes mellitus. There were 19 patients who were diagnosed as American Society of Anesthesiologists class Ⅰ and 14 patients who were diagnosed as class Ⅱ. The student t test,U test, χ² test or Fisher exact test was used to compare continuous data or categorized data,respectively. All the perioperative data and metabolic morbidity were analyzed and experiences on minimally invasive DPPHR were concluded. Results: Fourteen patients underwent laparoscopic DPPHR,while the rest of 19 patients received robotic DPPHR. Indocyanine green fluorescence imaging was used in 19 patients to guide operation. Five patients were performed pancreatico-gastrostomy and the rest 28 patients underwent pancreaticojejunostomy. Pathological outcomes confirmed 9 solid pseudo-papillary neoplasms, 9 intraductal papillary mucinous neoplasms, 7 serous cystic neoplasms, 6 pancreatic neuroendocrine tumors, 1 mucous cystic neoplasm, 1 chronic pancreatitis. The operative time was (309.4±50.3) minutes(range:180 to 420 minutes),and the blood loss was (97.9±48.3)ml(range:20 to 200 ml). Eighteen patients suffered from postoperative complications,including 3 patients experienced severe complications(Clavien-Dindo Grade ≥Ⅲ). Pancreatic fistula occurred in 16 patients,including 8 patients with biochemical leak,7 patients with grade B pancreatic fistula and 1 patient with grade C pancreatic fistula. No one suffered from the duodenal necrosis and none perioperative death was occurred. The length of hospital stay was 14(7) days (range:6 to 87 days). The follow-up was 22.6(24.5)months(range:2 to 74 months). None suffered from recurrence or metastasis. During the follow-up,all the patients were free of refractory cholangitis. Moreover,in the term of endocrine dysfunction,no postoperative new onset of diabetes mellitus were observed in the long-term follow-up. However,in the view of exocrine insufficiency,pancreatic exocrine insufficiency and non-alcoholic fatty liver disease (NAFLD) was complicated in 2 and 1 patient,respectively,with the supplement of pancreatic enzyme,steatorrhea and weight loss relieved,but NAFLD was awaited to be seen. Conclusions: Minimally invasive DPPHR is feasible and safe for benign or pre-malignant lesions of pancreatic head. Moreover,it is oncological equivalent to pancreaticoduodenectomy with preservation of metabolic function without refractory cholangitis.

Objective: To trace and characterize the whole genome of SARS-CoV-2 of confirmed cases in the outbreak of COVID-19 on July 31, 2021 in Henan Province. Method: Genome-wide sequencing and comparative analysis were performed on positive nucleic acid samples of SARS-CoV-2 from 167 local cases related to the epidemic on July 31, 2021, to analyze the consistency and evolution of the whole genome sequence of virus. Results: Through high-throughput sequencing, a total of 106 cases of SARS-CoV-2 whole genome sequences were obtained. The results of genome analysis showed that the whole genome sequences of 106 cases belonged to the VOC/Delta variant strain (B.1.617.2 clade), and the whole genome sequences of 106 cases were shared with the genomes of 3 imported cases from Myanmar admitted to a hospital in Zhengzhou. On the basis of 45 nucleotide sites, 1-5 nucleotide variation sites were added, and the genome sequence was highly homologous. Conclusion: Combined with the comprehensive analysis of viral genomics, transmission path simulation experiments and epidemiology, it is determined that the local new epidemic in Henan Province is caused by imported cases in the nosocomial area, and the spillover has caused localized infection in the community. At the same time, it spills over to some provincial cities and results in localized clustered epidemics.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:To analyze the clinical efficacy of Ganlu Xiaodu decoction combined with western medicine in the treatment of common coronavirus disease-2019（COVID-19）. Method:With the propensity score matching method，the clinical data of patients with common COVID-19 admitted to Wuhan Third Hospital from January 25，2020 to March 18，2020，were screened out. 115 patients with Ganlu Xiaodu decoction combined with conventional therapy were enrolled in the treatment group according to the inclusion and exclusion criteria，and 115 patients treated with conventional therapy were enrolled in the control group. The disappearance rate of main symptoms（fever，cough，expectoration，chest tightness，fatigue and panting），days of syndrome disappearance，effective rate and disappearance rate of other symptoms，laboratory indexes before treatment and after 7 days' treatment，effective rate in computed tomography（CT） of the lungs，rate of conversion to severe illness and total hospitalization time were compared between the two groups. Result:The baseline data between the two groups showed no statistically significant difference，but were comparable. After 7 days of treatment，the symptom disappearance rate of fever，cough，expectoration，chest tightness，fatigue and panting in the treatment group was significantly higher than that in the control group（P<0.01）.The average number of days to disappearance of main symptoms in treatment group was significantly less than that in the control group（P<0.01）. The effective rate of main symptoms was 93.9%（108/115）in treatment group, significantly higher than 75.7%（87/115，P<0.01）in control group. In the treatment group，the rate of conversion to severe illness was 0, significantly lower than 16.5% (19/115) in the control group (P<0.01). After treatment for 7 days，the white blood cell count，red blood cell count，c-reactive protein，calcitonin，and D-dimer in treatment group were significantly reduced（P<0.05），while lymphocyte count was significantly increased as compared with those before treatment（P<0.01）, the lymphocyte count in control group was also increased significantly in control group（P<0.01），while C-reactive protein，calcitonin and D-dimer were significantly reduced（P<0.05）. As compared with the control group，C-reactive protein and calcitonin levels in the treatment group were significantly down-regulated（P<0.01），and lymphocyte count rose significantly（P<0.05）.The improvement rate of pulmonary CT in the treatment group was 93.9%（108/115），which was significantly higher than 75.7%（87/115）in the control group（P<0.001）. After treatment，the patients in both groups were cured and discharged，and the average length of stay in the treatment group was（14.70±2.76） d，significantly less than（15.80±4.37） d in the control group （P<0.05）. No adverse events occurred in the treatment group but 6 cases occurred in the control group. Conclusion:Ganlu Xiaodu decoction combined with western medicine can significantly improve the clinical symptoms of common COVID-19 patients such as fever，cough，expectoration，chest tightness，fatigue, panting and shortness of breath，alleviate the main symptoms effectively，reduce the rate of conversion from common to serious COVID-19，regulate the expressions of relevant peripheral inflammation factors，promote absorption of lung inflammation，shorten hospitalization time，and improve the cure rate，indicating that Ganlu Xiaodu decoction can be effective in the treatment of patients with common COVID-19.
