Body weight change and metabolic index control in patients with type 2 diabetes mellitus under standardized metabolic disease management model / 中华内分泌代谢杂志

Objective:To explore the relationship between weight change and metabolic control of type 2 diabetic patients after 1 year treatment under the standardized metabolic disease management model.Methods:From November 2017 to November 2021, 950 patients with T2DM in the Standardized Metabolic Management Center of Suzhou Municipal Hospital were recruited in this research, who were divided into normal(BMI 18.5-23.9 kg/m 2), overweight(BMI 24.0-27.9 kg/m 2), and obese(BMI≥28 kg/m 2)groups according to baseline BMI. The metabolic indicators and control rates were compared. The overweight and obese 599 patients were divided into weight reduction(<-3 kg), maintenance(-3-1 kg) and gain(>1 kg)groups according to weight changes by one year, and metabolic indicators and control rates were compared to analyze the influence of weight change on metabolic control of overweight and obese patients. Results:(1) The overweight and obese groups had worse metabolic control at baseline and the obese group was younger. After 1 year, the metabolic indicators of three groups were significantly improved. (2) After 1 year, the metabolic control was better in weight reduction group and worse in weight gain group. The control rates were increased in weight reduction and maintenance groups. (3) For every 1 kg reduction in body weight of overweight and obese patients, blood glucose, blood lipids, blood pressure and comprehensive control rate increased by 1.206, 1.046, 1.069 and 1.107 times, respectively. There was a positive linear relationship between weight reduction and metabolic improvement.Conclusion:Standardized metabolic disease management model promotes metabolic control in type 2 diabetic patients, especially in overweight and obese patients who actively lose weight. In the future we should strengthen the management of overweight and obese patients, enhance self-management ability, and manage body weight scientifically and effectively.

Sequence Analysis of cytb Gene in Echinococcus granulosus from Western China

Echinococcus granulosus is the causative agent of cystic echinococcosis with medical and veterinary importance in China. Our main objective was to discuss the genotypes and genetic diversity of E. granulosus present in domestic animals and humans in western China. A total of 45 hydatid cyst samples were collected from sheep, humans, and a yak and subjected to an analysis of the sequences of mitochondrial cytochrome b (cytb) gene. The amplified PCR product for all samples was a 1,068 bp band. The phylogenetic analysis showed that all 45 samples were identified as E. granulosus (genotype G1). Ten haplotypes were detected among the samples, with the main haplotype being H1. The haplotype diversity was 0.626, while the nucleotide diversity was 0.001. These results suggested that genetic diversity was low among our samples collected from the west of China based on cytb gene analysis. These findings may provide more information on molecular characteristics of E. granulosus from this Chinese region.

Clinical analysis of parotid gland tumor in children / 中国耳鼻咽喉头颈外科

OBJECTIVE To investigate the clinical and pathological characteristics and its diagnosis and treatment of the parotid gland tumor in children.METHODS The clinical data of 77 children with parotid gland tumor treated in Department of Head and Neck,Tianjin Cancer Hospital affiliated Tianjin Medical University from Dec.1985 to Dec.2007 were retrospectively studied.RESULTS Among the 77 cases,51 cases were benign tumor(66.2%),26 cases were malignant tumor(33.8%).Among the benign cases,hemangioma and lymphangioma were the most common diseases,which accounted for 37.3%(19/51).Mucoepidermoid carcinoma(34.6%, 9/26) was the most common malignancy.Sixty seven cases were treated surgically.Among 18 cases of the epithelial malignant tumors,7 cases treated combined with postoperative radiotherapy.During the period of following-up from 1 to 17 years,1 case of pleomorphic adenoma,1 case of malignant myoepithelioma and 1 case of mucoepidermoid carcinoma recurred. CONCLUSION The clinical and pathological features of parotid gland tumors in children were different from those in adults.The hemangioma,lymphangioma and teratoma are rare in adults but common in children.Half of the solid tumors of parotid gland in children are malignant,but only 23.7%in adults. The primary radical operation has great value to the prognosis of children parotid tumor.Although postoperative radiotherapy can reduce the risk of recurrence,oncogenesis in thyroid gland and the adverse effect on the orofacial development of radiotherapy in children need investigated clinically in future.
