Objective To explore the effect and mechanism of sleeve gastrectomy （SG） for type 2 diabetes mellitus （T2DM） in Goto-Kakizaki （GK） rats. Methods Thirteen male GK rats at 12 weeks of age were randomly divided into SG group （n=7） and sham operation group （SO group， n=6）， receiving SG surgery and sham operation respectively.Body weight， food intake in 24hours， fasting plasma glucose， plasma glucagon-like peptide-1 （GLP-1）， and plasma Ghrelin of rats in 2 groups were measured or tested before operation， 1， 4， 10， and 26 weeks after operation. In 10 weeks after operation， fecal energy content of rats in 2 groups was tested， in addition， oral glucose tolerance test （OGTT） and insulin tolerance test （ITT） were performed to investigate the glucose tolerance and insulin sensitivity. Results ①Body weight：there were no significant difference on body weight between the 2 groups （P＞0.05）. Compared with time point of before operation， the body weight of both 2 groups decreased in 1 week after operation （P＜0.01）， but increased in 10 weeks and 26 weeks （P＜0.01）. ②Food intake in 24 hours：compared with SO group， the food intake of SG group were lower in 4 weeks and 10 weeks after operation （P＜0.05）. Compared with time point of before operation， the food intake of SG group were lower in 1， 4， and 10 weeks after operation （P＜0.05）， but lower only in 1 week in SO group （P＜0.05）. ③Value of fasting glucose：compared with SO group， the value of fasting glucose in SG group were lower after operation （P＜0.01）. Compared with time point of before operation， the value of fasting glucose of SG group were lower after operation （P＜0.01）， but decreased in 1 week only in SO group （P＜0.01）. ④Level of serum GLP-1：compared with SO group， the levels of serum GLP-1 in SG group were higher in 4， 10， and 26 weeks after operation （P＜0.05）. Compared with time point of before operation， the levels of serum GLP-1 in SG group were higher in 4， 10， and 26 weeks after operation （P＜0.05）， but levels of serum GLP-1 in SO group didn’t change significantly （P＞0.05）. ⑤Level of serum Ghrelin：compared with SO group， the levels of serum Ghrelin in SG group were lower at alltime points after operation （P＜0.01）. Compared with time point of before operation， the levels of serum Ghrelin in SGgroup were lower at all time points after operation （P＜0.001）， but levels of serum Ghrelin in SO group didn’t change significantly （P＞0.05）. ⑥Areas under curves （AUC）：the AUC of OGTT and ITT test in SG group were both lower than those of SO group （P＜0.01）. Conclusion SG surgery can induce the level of fasting plasma glucose， and canimprove glucose tolerance and insulin sensitivity with significant changes of levels of plasma GLP-1 and Ghrelin， sugg-esting that SG surgery may be a potential strategy to treat patient with T2DM but without obesity or insulin resistance.

Objective To establish and evaluate the hind limb ischemia model in type 2 diabetic rats， and to providea platform for subsequent intervention experiment. Methods Fifteen SD rats were randomly divided into 3 groups：normal control group， diabetes group， and diabetic ischemia group， each group enrolled 5 rats. The 10 rats of later 2 groups were fed with high fat diet for 4 weeks， and then received intraperitoneal injection of streptozotocin （40 mg/kg） to establish type 2 diabetic model. Three days later， the rats of diabetic ischemia group underwent ligation of the bilateral common iliac artery to establish the hind limb ischemia model， but iliac artery of rats in other 2 groups didn’t received ligation. Ultrasound and color Doppler flow imaging detection was used to determine the peak velocity and acceleration time of femoral artery in rats of 3 groups in 2 weeks after operation， and triceps tissues and quadriceps tissues were collected to perform HE staining and SP staining for the observation on status of nutrition and vascular regeneration respectively. Results The peak velocity of femoral artery in rats of normal control group， diabetes group， and diabetic ischemia group were （22.49±3.02） cm/s， （17.36±2.60） cm/s， and （11.23±1.26） cm/s， the acceleration time were （0.080±0.009） s，（0.120±0.009）s， and（0.160±0.020） s， the arteriolar density measured by immunohistochemistry SP method were 6.80±0.84/HPF， 4.60±0.55/HPF， and 1.40±0.55/HPF respectively. The peak velocity of femoral artery and arteriolar density of rats in diabetic ischemia group were both lower （P＜0.05）， but acceleration time was longer （P＜0.05）. Results of HE staining showed that structure of triceps tissues was damaged， with infiltration of lots of inflamm-atory cells， which was worse than normal control group and diabetes group. Conclusion Method of high-fat diet in combination with small dose of streptozotocin can induce type 2 diabetic rat model， and hind limb ischemia model can be successfully established by ligation of common iliac artery on this model.
Objective To investigate and analyze the incidence and clinical characteristics of malnutrition in patients with tuberculosis and type 2 diabetes. Methods four hundred patients with tuberculosis and type 2 diabetes were diagnosed in the tuberculosis Department of West China Hospital of Sichuan University from June 1, 2018 to April 30, 2023. The incidence and clinical characteristics of malnutrition were analyzed using the nutritional risk Screening 2002 score and the Global Malnutrition Leadership Initiative criteria. Results 170 patients (42.5%) were malnourished. In malnourished patients, 78 cases (45.9%) had fever, 132 cases (77.6%) had cough, 44 cases (25.9%) had hemoptysis, and 36 cases (21.2%) had night sweating. Compared with the non-malnourished patients, the difference was statistically significant (P<0.05). Lymphocyte count was (1.0±0.5)×109/L, albumin was (31.4±20.5)g/L; CD3 count 792.7±205.0, CD4 count 535.4±15.0, CD8 count 429.5±123.0, CD3%: 65.5%±11.1%, CD4%: 39.1%±9.6%, CD8%: 19.1%±9.6%, CD4/CD8: 1.3±0.2, which were significantly lower than those in the group without malnutrition. Pulmonary cavity occurred in 44 cases (25.9%), lesions in 2 - 4 lung fields in 76 cases (44.7%) and lesions in ≥5 lung fields in 52 cases (30.6%), all of which were significantly higher than those in the non-malnutrition group. The above differences were statistically significant.Conclusion We should pay more attention to the screening of malnutrition in patients with tuberculosis and type 2 diabetes. Patients with malnutrition have more obvious clinical symptoms, lower immunity, and more serious imaging lesions.
