ObjectiveTo comprehensively evaluate the curative effect ofTCM reating type 2 diabetes with three type dialectical therapy by Fuzzy Mathematics.Methods261 cases of 2 type diabetes were divided into three groups by syndrome differentiation,as follows:type of heat with yin deficiency,type of deficiency of both qi and yin,and type of deficiency of both yin and yang,and received corresponding therapies.The course of treatment was 24 weeks,in the first 12 weeks (period 1),on the basis of western medicine treatment,patients of the three groups were respectively treated by qingrungranules,ziyigranule and shuangtiaogranules.In the next 12 weeks (period 2),all patients were only treated by western medicine.The value of FBG,P2BG,HbAlc,TC,TG,BMI of the two periods were comprehensively evaluated by the methods of fuzzy mathematics.ResultsAt the end of period 1,the total effective rate of the type of heat with yin deficiency was 91.38％,the type of deficiency of both qi and yin was 87.16％,and the type of deficiency of both yin and yang was 83.34％; while at the end of period 2,the total effective rate of the three types was 59.18％,48.65％a nd32.65％ respectively.ConclusionThe effective rate was obviously improved in period 1; while in period 2,the effective rate was decreased.

Objective To investigate the incidence of the pusher syndrome in stroke patients, and the relationship between the syndrome and the neuropsychological symptoms and location of brain lesion, and to investigate the mechanism and the physiotherapy intervention of pusher syndrome. Methods Thirty nine patients(25 male, 14 female, 62.5?9.4 years old) with pusher syndrome were examined, 91 patients(57 male,34 female, 58.4?11.6 years old) without ipsilateral pushing served as control. The lesion areas, neuropsychological syndrome and the Barthel Index(BI) were recorded, and the physiotherapy were administered in the patients. Results The incidence of pusher syndrome was 30% in the patients studied, corresponding to 17% of the total number of stroke patients in the study period. The percentage of pusher syndrome occurrence was higher in the patients with right side lesion than those with left side lesion ( P

Objective To probe the value of clinical application of three dimensional contrast enhanced magnetic resonance angiography (3D CE MRA) for diagnosis of peripheral artery occlusive diseases (PAOD) and to assess its accuracy. Methods One hundred and three cases of PAOD received 3D CE MRA before operation. And 579 vascular segments were displayed. The diagnosis of 3D CE MRA before operation were compared with the results of vascular reconstruction surgeries of lower extremities. The image quality and how 3D CE MRA revealed the abnormal blood vessels were evaluated. Results Satisfactory images of the main arteries of the lower extremities were achieved by 3D CE MRA. In 579 vascular segments of 103 patients with PAOD,the sensitivity and specificity for detection of severe stenosis and occlusions were 97.6% and 95.4%,respectively. In 206 vascular segments of tibiofibula artery,the sensitivity was 100%. In 196 vascular segments of femoral artery,the specificity was 97%. Conclusion 3D CE MRA is accurate and reliable for determination of the degree of peripheral artery stenosis. The results of 3D CE MRA are concordant with that of operation.

Objective To elevated the decontam ination properties of commercial nanoscale metal oxides against chemical warfare agents (CWA), and provide more foundation for the satisfactory materials of CWA decontamination. Methods Some nanocrystals of commercial metal oxides such an MgO, TiO2, ZnO and zinc nickel ferrite compound had been chosen to compare their decontamination properties. The nanocrystals were mixed with three representative compounds, sulfur mustard (HD), soman (GD) and S-(2-diisopropylaminoethyl) O-ethyl methylphosphonothioate (VX) at room temperature and natural light. The analogous experiments were conducted without addition of nanocrystals as negative control. After a fixed time, the samples were then analyzed by the methods of T-135, Schoeneman reaction and conversion method to determine the content of CWA. The decontamination properties of nanocrystals were compared with negative control. Results The chosen nanoscale metal oxides excepted nanoscale MgO had good decontamination properties against HD, and they all could decontaminate GD quickly. Nanoscale TiO2 had superior decontamination properties against GD and HD. At the room temperature and natural light, HD was completely decontaminated within 20 hours and GD was completely decontaminated within 4 hours by nanoscale TiO2. The nanocrystals of metal oxides didn′t decontaminate VX effectively. Compared to the activated clay group, nanoscale MgO had superior decontamination properties against VX over other nanocrystals (P<0.05), but the percentage of degradation was lower than 20% within 7 h. Conclusion The chosen nanoscale TiO2 has superior decontamination properties against GD and HD than others in natural condition, but it isn′t a promising agent for the decontamination of VX.

Two Pseudomonas strains, K80 - B and K80 - A, can use hydrocarbon as carbon source by two different mechanisms. Different effects can be observed when they are applied to 69-8 oil of Dagan Oil Field. The strain K80-B producing both hydrocarbon pseudosolubilizing factor and hydrocarbon emulsifying factor can decrease the viscosity and solidifying point of the 69-8 oil 51.6% and 2℃ respectively. Whereas the other can only decrease 43.5% and 3℃ respectively. When the two strains are mixed, synergistic effect on crude oil is obvious.

Objective To investigate the changes of enteric nervous system in gastrointestinal motility disorder in rats with severe acute pancreatitis (SAP) as well as the influence of Chaishao Chengqi Decoction on neuronal nitric oxide synthase neuron (nNOS) neuron expression in myenteric plexus of rat intestinal tract. Methods SD rats were randomly divided into 3 groups (10 for each): sham operation group, model group and Chaishao Chengqi Decoction (CSCQD) group. SAP model was established in taurocholate into the junction of the common bile duct and pancreatic duct. Model group was administered with normal saline and CSCQD group was administered with Chaishao Chengqi Decoction. The gastrointestinal transmission time was observed. Pathological changes of the pancreas were examined with HE staining under light microscope. The neuronal nitric oxide synthase neurons in the small intestines and colonic myenteric plexus were detected by the dual immunofluorescent staining. Results Compared with that in model group, transmission index was increased in CSCQD group (P<0.05). The pathological lesion of the pancreas in CSCQD group was significantly lessened (P<0.05). The percentage of NOS-immunoreactive neurons was significantly decreased (P<0.05). Conclusion By reversing the plasticity of NOS-immunoreactive neurons, Chaishao Chengqi Decoction improves the gastrointestinal motility in rats with SAP and reduces the pathological damages of the pancreas.

Objective To evaluate the role of 5-HT5A receptors (5-HT5A R) in activation of astroglia in the spinal dorsal horn in a rat model of neuropathic pain induced by vincristine. Methods Forty adult male SD rats weighing 180-200 g were randomly divided into 4 groups ( n = 10 each): control group (group C);neuropathic pain group (group P);Ad-X-HK group (group B) and Ad-5-HT5A-siRNA group (group S). Neuropathic pain was induced by repeated intraperitoneal (IP) injection of vincristine 0.1 mg/kg according to the method described by Weng et al in group P, B and S. On the 2nd day after the last IP injection, the animals received artificial cerebrospinal fluid, Ad-X-HK and Ad-5-HT5A-siRNA 25 μl administered intrathecally (IT) in group P, B and S respectively. Paw withdrawal threshold to mechanical stimulus was measured before and on the 7th day after IT administration. The animals were then sacrificed. The lumbar segment ( L4.5 ) of the spinal cord was removed for determination of 5-HT5A R and GFAP expression. Results Body weight and paw withdrawal threshold were significantly decreased after repeated IP vincristine administration in group P compared with group C. IT Ad-5-HT5A-siRNA reduced pain threshold further in group S compared with group P. Repeated IP vincristine significantly increased the expression of 5-HT5A R and GFAP in spinal dorsal horn, and IT Ad-5-HT5A-siRNA significantly decreased the expression of 5-HT5A R while increased the expression of GFAP in spinal dorsal horn in group S compared with group P. Conclusion 5-HT5AR is involved in the inhibition of astrocyte activation, resulting in reduction of vincristineinduced neuropathic pain.
