Objective To investigate the role of glargine in glucose metabolism improvement and antiinflammation of skeletal muscle in Caveolin-1 silenced type 2 diabetic mice.Methods Multiple low doses of streptozotocin (STZ) intraperitoneal injection and high-fat high-glucose (HFHG) were used to induce type 2 diabetic mice model.The mice were divided into normal control group (NC group) and type 2 diabetic model group (T group).Then according to virus injection and glargine treatment,T group were further divided into type 2 diabetes group (T2DM group),type 2 diabetes with insulin treatment group (insulin group),Caveolin-1 silenced with insulin treatment group (LV-CAV1 group),and scramble virus with insulin treatment group (LV-GFP group).Glucose metabolism was accessed by the fluctuation of blood glucose.TNF-α protein expression in skeletal muscle was detected by Western blot.Results The glycemic control of LV-CAV1 group needed more dosages of glargine (P ＜ 0.05).The expression of TNFαin skeletal muscle was elevated in LV-CAV 1 group than that in LV-GFP and insulin group (P ＜ 0.05).Conclusion The anti-inflammation function and glycemic metabolism improvement of glargine may be associated with the expression of Caveoin-1 in skeletal muscle.

Objective To investigate the relationship between blood glucose levels and severity of coronary stenosis in hypertensive patients. Methods Blood pressure, fasting plasma glucose, 2 h plasma glucose, clinical features and coronary angiographic findings were analyzed retrospectively in 540 patients with essential hypertension. Acoording 2 h plasma glucose, patients were stratified into three group: group 1: 2h plasma glucose

Objective To detect the epidemiologic features of pediatric patients with fall from height injury in an effort to provide a reference for prevention and scientific treatment.Methods Data of pediatric patients with fall from height injury treated from January 2011 to December 2012 were collected in the form of questionnaires.Epidemiologic features and relationship of associated factors were measured.Results Pediatric fall injury occurred very often in warmer season,namely on April and May,and in a day,it was more likely to happen when parents slacked at noon and night.Stairs and balconies were the most common sites of falls and head was most vulnerable to the injury.Falling height was the primary factor to the severity of injury.Conclusion To strengthen the protection reform in key areas,the supervision in peak time for falls and the care to children of the migrant workers can reduce fall injury in a certain extent.

Leprosy is a chronic granulomatous infection caused by Mycobacterium leprae, which primarily affects the skin and peripheral nerves. In this article, we present a 45-year-old man and a 39-year-old women who suffered from asymptomatic irregular erythemas on their trunk and extremities. Since both patients denied the history of exposure to leprosy patients and were absent clinical signs of superficial sensation dysfunction and enlarged peripheral nerves, they were diagnosed of mycosis fungoides and livedo reticularis clinically. Nevertheless the biopsies of erythemas showed perineural and periadnexal foamy-cell granulomas in the dermis and Fite staining revealed a large number of acid-fast bacilli. A diagnosis of multibacillary leprosy was made finally. These cases revealed that since leprosy is still epidemic in some remote area in China and in other developing countries and its clinical manifestations may be very weird sometimes, the dermatologists should be alert of it and skin biopsy could confirm the diagnosis.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

Objective: To explore the action mechanism of electroacupuncture (EA) in improving the gastric motility of rats with diabetic gastroparesis (DGP). Methods: Forty-eight healthy Sprague-Dawley (SD) rats were randomly assigned into four groups: a normal group (group A), a model group (group B), a group of EA at acupoints (group C), and a group of EA at non-acupoints (group D), 12 rats in each group. The animal model of DGP was established by intraperitoneal injection of streptozotocin (STZ) plus high glucose and fat diet. The blood glucose, urine glucose and gastric emptying rate (GER) were observed. The content of insulin (INS) in serum and ghrelin in gastric antrum tissue were detected by enzyme linked immunoassay (ELISA). The expression of growth hormone secretagogue receptor mRNA (GHSR mRNA) in gastric antrum tissue was detected by real-time fluorescent quantitative polymerase chain reaction (PCR). Results:Compared with group A, blood glucose and urine glucose increased significantly (P<0.01), GER, content of serum insulin, the content of ghrelin and expression of GHSR mRNA in gastric antrum tissue decreased significantly (P<0.05 orP<0.01) in group B. Compared with group B, blood glucose and urine glucose decreased significantly (P<0.05), GER, the content of insulin in serum, the content of ghrelin and expression of GHSR mRNA in gastric antrum tissue increased significantly (P<0.05 orP<0.01) in group C. Conclusion: EA at acupoints can down-regulate the content of blood and urine sugar, and promote gastric emptying, which is possibly related to the regulation of serum insulin, and the expressions of ghrelin and GHSR mRNA in gastric antrum.

Objective To study the relationship among apoptosis,NF-KB activation and uPA expres- sion in human colon carcinoma cell line HCTll6 induced by 5-fluorouracil,and to observe the effect of in- hibiting activity of NF-KB by PDTC on apoptosis as well as expression of uPA.Methods Cell apoptosis was analysed by Annexin V-FITC.Fluctuation of NF-KB and uPA was detected by semi-quantitative immuno- histochemistry.Results 5-fluorouracil could induce apoptosis and activate NF-KB.PDTC could significantly increase the apoptosis and suppress the activation of NF-KB induced by 5-fluorouracil.There was a positive correlation between the changes of uPA and NF-KB.Conclusion 5-fluorouracil could induce apoptosis,ac- tivate NF-KB and up-regulate expression of uPA of HCT116 cells.The mechanism of enhanced apoptosis by PDTC may be related to suppressing activation of NF-?B and down-regulating expression of uPA.
