Objective To observe the effects of resistant starch (RS) on insulin resistance (IR) in type 2 diabetes mellitus rats. Method Male Wistar rats (n=40) were used.Ten were fed with normal diets (normal control group) and the others with high fat (safflower oil, 59% of total energy) diet (model group) . Ten weeks laters, the model group was injected with streptozotocin (20mg/kg bw) and divided into 3 groups: diabetes control group, high fat and RS intervention group, RS intervention group. After 5 w, oral glucose tolerance test (OGTT) was carried out in each group and the metabolism of glucose and lipid, insulin sensitivity, pathological changes of liver and kidney were observed. Results Compared with diabetes control group, insulin sensitivity index (ISI) was higher and area under curve (AUC), fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), low density-lipoprotein cholesterol (LDL-C) were significantly lower in RS intervention groups. Besides, the fatty degeneration of liver was much lighter but glycogen synthesis was significantly increased. Conclusion RS is effective in improving IR of type 2 diabetes mellitus rats.

Objective:To investigate the effect of modified Dihuang decoction on expression of c-fos positive neuron in hippocampal CA1 area in diabetic rats. Methods:The diabetic rat models were induced by intraperitoneal injection of streptozotocin(STZ) . 4 weeks later,the expression of c-fos was detected by immuno-histochemistry. Results:Compared with diabetes group(9.25?2.36,0.56 ?0.06) ,the positive cell's density and average light density(8.13?1.70,0.46?0.08) of c-fos positive neuron in hippocampal CA1 area in diabetic rats which were prevented and treated with modified Dihuang decoction both decreased(P

Tuberculosis of bone and joint most commonly occurs in spine, and the main treatment method is anterior debridement, bone grafting and internal fixation. Autologous bone is still considered the "gold standard" when the anterior reconstruction of spine after debridement is needed. Allogeneic bone, artificial bone and artificial intervertebral support bodies such as titanium mesh and some biological materials also have a broad clinical application, but still can not completely replace the autologous bone because of their defects. In the aspect of internal fixation, anterior fixation has become a conventional method for the patients who suffer from active spinal tuberculosis and need anterior debridement of the focus, because this method can provide good support. This review summarizes the present situation of choice for supporting and bone grafting material for anterior reconstruction after debridement of spinal tuberculosis.

The CAPN10 gene, which encodes calpain-10 ( CAPN10 ), a nonlysosomal cysteine protease expressed in many tissues, including skeletal muscle, liver, and pancreas, was positionally cloned within the NIDDM1 region. This putative diabetes susceptibility gene encodes a 672 amino-acid protein. Horikawa et al, determined that the CAPN10 gene consists of 15 exons and spans 31 kb. Recently, researchers in many countries have examined the impact of CAPN-10 gene on T2DM. The three SNPs existence simultaneously can increase threefold risk of T2DM. The correlation between them with racial diversity is also reviewed.

[Objective] To discuss the expression and meaning of NOS and BDNF in the lateral zone of rats’ hypothalamus with diabetes. [Method] Inject STZ 50mg/kg into the abdomen for rats model of diabetes, after 1 month, observe the positive neuron expression of LH NOS in rats’ hypothalamus with diabetes with NADPH-d enzyme histo-chemical method, to the positive neuron expression of LH BDNF with NADPH-d immunohisto-chemical method. [Result] The expression of NOS and BDNF is both lowered compared with normal group, P

Objective: To observe the efficacy and safety of apatinib combined with chemotherapy or endocrine therapy in the treatment of relapsed and refractory breast cancer. Methods: The clinical records of two patients with relapsed and refractory breast cancer treated with apatinib combined with chemotherapy or endocrine therapy were analyzed, and the related literatures were reviewed. Results: Two patients with relapsed and refractory breast cancer were treated with apatinib combined with chemotherapy or endocrine therapy and followed up for 10 months. The treatment outcome was stable disease. Major adverse reaction was hypertension, and the use of antihypertensive drugs could control the blood pressure in a normal range. Conclusion: Apatinib combined with chemotherapy or endocrine therapy in the treatment of relapsed and refractory breast cancer is effective, and the adverse effects are tolerated. Large-scale studies should be implemented to further determine the efficacy of this treatment protocol.

Objective:The glucemic index(GI)and insulin index(II)of wheat flour, oat fiber and resistant starch (RS) were studied.Method:Ten healthy subjects consumed 4 kinds of carbohydrate foods: glucose powder,wheat flour food, oat fiber food and RS food.Up to 120 min after consumption of test materials, blood samples were taken for glucose and insulin analyses.Results:The GI value of wheat flour food, oat fiber food, RS food was 88.24?20.84,60.16?14.16,47.05?10.22 respectively,regarding glucose powder as 100 . The II value of them was 83.06 ? 10.68 , 68.32 ? 17.08, 60.26 ? 30.1 respectively.The area and peak level under the glucose-response curve and insulin-response curve of RS food were significantly lower than those of glucose powder and wheat flour food (P

Objective: To examine the effects of RS on serum cholesterol and expression of genes associated with cholesterol metabolism in rat liver for understanding its mechanism. Method: Eighteen rats were randomly assigned to three groups, six rats each. They were fed with chemical purified normal diet (control group), low RS (15%Hi-maize 1043) diet and high RS (30%Hi-maize 1043) diet respectively. Six weeks later, serum cholesterol and short chain fatty acid (SCFA) in the cecum were measured. Likewise, hepatic cholesterol 7?-hydroxylase, LDL receptor, and SR-B1 mRNA levels were measured by realtime PCR. Results: Hepatic cholesterol 7a-hydroxylase, LDL receptor, SR-B1 mRNA levels and cecal acetate, propionate and n-butyrate concentrations in the high RS group were significantly higher than those in the control group (P

Objective To assess the diagnostic value of the latent membrane protein 1(LMP-1)gene detection for diagnosing na-sopharyngeal carcinoma(NPC).Methods The related researches on the detection of LMP-1 gene in the nasopharyngeal swab secre-tion for diagnosing NPC by PCR were entirely collected by using the computer retrieval or manual inquiring.Two estimators screened the literature according to the criteria of inclusion and exclusion.The quality evaluation was performed by adopting the QUADAS scale.The heterogeneity test was conducted by using Meta-Disc 1.4 software.According to the heterogeneous character-istics,the corresponding effect model was selected for calculating the pooled sensitivity and specificity and the summary receiver op-erating character(SROC)curve was drawn.Results 139 related articles were retrieved,in which 6 articles were finally included. 394 cases of NPC were definitely diagnosed by the pathological golden standard,802 cases were in the control group.The pooled sensitivity and specificity of the LMP-1 gene for diagnosing NPC were 0.90[95%CI (0.87,0.93)]and 0.98[95%CI (0.96,0.99)] respectively.The area under SROC(AUC)was 0.973 7.Conclusion LMP-1 gene has the higher diagnostic value for NPC and could be used for screening and auxiliary diagnosis of NPC.
