1.Decreased fibroblast proliferation and collagen content in the wound of diabetic rats caused by streptozotocin
Chinese Journal of Pathophysiology 1999;0(09):-
AIM: To study fibroblast proliferation and collagen synthesis during wound healing in diabetic rats induced by streptozotocin. METHODS: 30 Wistar male rats were randomly divided into control group and model group. 55 mg/kg STZ were given intraperitoneally to model rats. After 3 weeks, a round skin of 2.04 cm~2 was excised on all dorsal back of rats. The healing time and healing rate were observed according to re-epithelization. The numbers of fibroblasts and the expression of proliferating cell nuclear antigen (PCNA) were observed by Hematoxylin-Eosin (HE) staining and immuno-histochemistry assay. Collagen Ⅰ and Ⅲ stained by Picric acid-Sirius red were calculated by image analysis. RESULTS: The healing time in model group was (27.13?1.81) days,significantly longer than that in control group [(15.25?1.67) days, P

Objective To observe the clinical effects of modified Shengxian decoction in the treatment of thyroid cancer postoperative hypothyroidism patients.Methods 60 patients of thyroid cancer postoperative hypothyroidism due to deficiency of spleen and kidney were randomly divided into a control group and a treatment group.The control group (28 cases) was by levothyroxine sodium tablets conventional treatment,while the treatment group (32 cases) was treated with Shengxian decoction based on thecontrol group.The changes of the symptom integral and HAMD-17 were observed between two groups before and after treatment.Results After treatment,the total effective rate was 87.5% in the treatment group and 64.3% in the control group,the clinical effect of treatment group was significantly better than the control group (x2=4.499,P< 0.05).After treatment,the total score of HAMD-17 was 6.8±2.3 in the treatment group and 15.8±2.1 in the control group,both significantly improved than that before the treatment (which were 19.4±1.45 and 18.9± 1.32 respectively).Compared with the control group,the treatment group improved significantly (P< 0.01).Conclusion Shengxian decoction plus western medicine has remarkable curative effect in the treatment of thyroid cancer postoperative hypothyroidism,it can improve the depressive state of patients and improve the quality of life.

AIM: To study the effects of Yangyu Tuji (YYTJ) on delayed healing wound of diabetic rats caused by streptozotocin (STZ). METHODS: SD male rats were randomly divided into control group (control), model group (model); and 3 different dose groups of YYTJ. 55 mg/kg STZ were given by intraperitoneal injection except for control group. After 30 days, a round skin of 1.6 cm diametre was excised on all dorsal back of rats. The healing time and healing rate were observed according to re-epithelization. The content of collagenⅠ and Ⅲ was observed by Picric acid-Sirius red staining , Matrix metalloproteinase-1, 13 (MMP-1, -13), tissue inhibitor of metalloproteinases-1 (TIMP-1) by immuno-histochemistry assay. All data were analyzed by IPP software. RESULTS: The healing time in each group treated with YYTJ was shorter than that in model group (P

The 81st annual scientific meeting of the American Diabetes Association (ADA) was held online from June 25 to 29, 2021. The conference encompassed following theme areas: Acute and chronic complications of diabetes, behavioral medicine, clinical nutrition, education and exercise, clinical diabetes/therapeutics, epidemiology/genetics, immunology/transplantation, insulin action/molecular metabolism, integrated physiology/obesity and islet biology/insulin secretions, which covers both clinical and basic aspects of diabetes mellitus and other metabolic diseases. Here is the summary of the main points of academic progress in diabetes and other metabolic diseases.
