To investigate the effects of Tongxinluo capsule on sciatic nerve apoptosis in spontaneous type II diabetic KK/Upj-Ay mice, in order to explore its mechanism for improving diabetic peripheral neuropathy (DPN). KK/Upj-Ay mice were selected as the DPN animal model and randomly divided into the model, Tongxinluo low, middle and high group (1, 2, 4 g x kg(-1)). C57BL/6 mice were selected as the control group. Mice were given intragastrically for 12 weeks. Paw withdrawal latency, motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) were detected. Apoptotic rate were detected by FCM. Bcl-2, Bax, Caspase-3 mRNA and protein expression in sciatic nerve were examined by Real-time PCR and Western blot. p38MAPK, p-p38MAPK expression were examined by Western blot. In this study,the authors found that Tongxinluo capsule could increase paw withdrawal latency, MNCV and SNCV. Apoptotic rate of sciatic, the expression of Bax and caspase-3 were lower, while Bcl-2 expression was higher in Tongxinluo group than those in model mice. The expression of p-p38MAPK significantly decreased in Tongxinluo group. The results showed that Tongxinluo capsule has protective effects on diabetic peripheral neuropathy of mice via inhibiting cell apoptosis and suppressing the expression of p-p38MAPK.

Objective To discuss two simulation studies on the closed and open peritoneum in abdomenal operations. Meth-ods We selected 120 domestic female rabbits from animal laboratory of Qi Qi Ha’er Medical College at random and divided them into four groups(according to whether the peritoneum was open or not,the degree of peritoneum defect at the right side of incision and the existence of peritoneum hemorrhagic focus ),with 30 cases in each group. Group Ⅰ: no peritoneum suture and making a defect of 4cm?3cm at the right side of the incision; Group Ⅱ: no peritoneum suture and making a defect of 4cm?3cm at the right side of the incision,with a hemorrhagic focus at peritoneum defect;Group Ⅲ: with peritoneum suture; Group Ⅳ:with dense and compact peritoneum suture.And then we analyzed postoperative peritoneum healing progress. Results Observeations of the incision infection by the naked eye were that one case was identified in group Ⅰ,Ⅲ and Ⅳ;and a significant difference of occurrence rate was identified between the fallowing groups: groupⅠandⅡ(P

Objective To investigate the effects of angiotensin Ⅱ (Ang Ⅱ) on the expression of vascular endothelial growth factor (VEGF) in human hepatic cancer cell line Hep G2.Methods Cultured Hep G2 cells were treated by AngⅡ with various concentrations and were collected at different time points.Then total RNA was extracted.The expression of VEGF mRNA in cultured Hep G2 was determined by relative quantitative reverse transcription polymerase chain reaction(RT-PCR),and the proliferation was detected by methyl thiazolyl tetrazolium (MTT).Results AngⅡ stimulated the proliferation of HepG2 cells,and enhanced the expression of VEGF mRNA (P

Objective:To explore the relationship among blood glucose,blood lipid levels,peripheral blood white cells and slow coronary flow (SCF).Methods:Clinical data of 183 patients receiving angiography in our hospital from Apr 2010 to Apr 2013 were retrospectively analyzed.Patients with TIMI grade 2 or lower coronary blood flow were defined as SCF;patients were divided into SCF group (n=93)and normal control group (n=90).Levels of blood lipid,glycosylated haemoglobin (HbA1c),hematocrit,and peripheral blood white cell levels were measured and compared between two groups.Results:Compared with normal control group,there was significant reduction in high density lipoprotein cholesterol (HDL-C) level [(1.21 ± 0.26)mmol/L vs.(1.12 ± 0.28)mmol/L,P =0.043],and significant rise in HbA1c level [(5.41±0.50)% vs.(5.83±0.45)%,P =0.01],hematocrit [(0.41 ±0.04)vs.(0.43±0.07),P =0.01]and white blood cell count [(6.1±1.6)109/L vs.(6.7±1.7)109/L,P <0.05]in SCF group.Logistic analysis indicated that white cell count was the risk factor of SCF (OR 1.920,95% CI 1.234~2.987,P =0.004).Conclusion:Levels of high density lipoprotein cholesterol,glycosylated haemoglobin, hematocrit and white blood cell count are related to slow coronary flow,and elevated white blood cell count may be a risk factor aggravating slow coronary slow.

Objective To explore the characteristics of food preferences in children with autism spectrum disorder,in order to provide some reference for treating the odd diet habits.Methods Comparing food selection styles through a self-made parents questionnaire including 113 kinds of common food in six categories in China in 162 cases of neurotypical children (NC) and 162 cases of children with autism (AC) to investigate the food preference characteristics of autistic children.Results Compared with NC,AC had narrow food repertoire in grain (NC refuse 0.0(1.0),AC refuse 1.0(2.0),P＜0.001),beans(NC refuse 0.0(1.0),AC refuse 1.0(2.0),P＜ 0.05),meat (NC refuse 0.0 (0.0),AC refuse 0.0 (2.0),P＜ 0.05),vegetables (NC refuse 3.0 (5.0),AC refuse 6.0(1.0),P＜0.001) and fruits(NC refuse 0.0(1.0),AC refuse 2.0(5.0),P＜0.001).There was no difference in the food preferences in neurotypical children of different gender.However,AC boys were more selective in the grain (NA girls refuse 0.0 (1.0),AC boys refuse 1.0 (2.0),P＜ 0.05) and vegetables (NA girls refuse 3.5 (5.0),AC boys refuse 7.0(11.0),P＜0.05) than AC girls.Moreover,AC had higher preference to lower acceptance in most of food than NC,but not instant noodles(NC acceptance 71.01％,AC acceptance 81.02％,P＜0.05) and chilli (NC acceptance 20.71％,AC acceptance 28.47％,P＜0.05).Conclusion Compared with NC,AC have narrower food repertoire.On the other hand,AC have significantly higher acceptance of stimulating food like chili and instant noodle.

Objective To investigate the research status of domestic TCM systems biology in recent ten years, and provide reference for further research. Methods TCM systems biology literatures published in domestic journal were retrieved and screened. The data were analyzed from the annual distribution, regional distribution, research institutions, source journals, research fields, and so on. Results The total literature of TCM systems biology showed an increasing tendency. The research mainly distributed in TCM chemical matteromics, TCM genomics, TCM proteomics, TCM metabolomics, and TCM informatics. Beijing, Guangdong and Shanghai were in the leading position. Conclusion The development trend of domestic study on TCM systems biology is rising year by year, and the understanding of the subject is continuously improving.

Heparin and low molecular weight heparin have been widely used in clinical therapy as anticoagulants in cardiovascular disease and in hemodialysis. Crude heparin is usually prepared from porcine intestinal mucosa. Purified heparin is a mixture of polysaccharides consisting mainly of repeating GlcNS(6S)-IdoA2S disaccharides and other disaccharides with different GlcNAc/GlcNS±3S±6S-GlcA/IdoA±2S residues. Heparin injections are drugs prepared from heparin active pharmaceutical ingredient ( API ) that is prepared from crude heparin. Low molecular weight heparins are dominant heparin-based drugs used clinically, which are prepared by degrading heparin into smaller sizes. As a result, low molecular weight heparins are sharing the same major disaccharides but have different reducing and non-reducing ends. In current study, we focused on the disaccharide compositional analysis of clinically used heparin and heparin-based drugs. HeparinaseⅠ,II, and Ⅲ were used to degrade all heparin and heparin-based drugs including heparin sodium injection, Enoxaparin sodium injection, Nadroparin calcium injection, Dalteparin sodium injection, Fondaparinux sodium into disaccharides. All the degraded products were analyzed by strong anion high perforance liquid chromatography ( SAX-HPLC) coupled with an UV-detector. Commercially available unsaturated disaccharide standards were then used for structral identification. Furthermore, unusual disaccharides present in Nadroparin, Dalteparin, and Fondaparinux were confirmed by reversed-phase ion pair HPLC coupled with mass spectrometry. The developed method produced detailed structural information, which should be useful for quality control of heparin and heparin-based drugs.

The mode of action of V-type organophosphate poisons on acetylcholinesterase has been studied. It shows that the leaving group of V-type poisons is dialkylamino-ethyl-thio radical,and the phosphonyla-ting site on the enzyme molecule is similar to that of the G-type poison soman, as shown by the competition experiments.
