Objective To investigate the anti-fatigue effect of complex bear gall agent in mice.Methods Different dose of complex bear gall agent(4.4ml/kg、6.6ml/kg、13.2rml/kg)were given to mice by intragastric administration. The time of climbing-pole and loaded-swimming, hepatic glycogen content, serum urea nitrogen,lactic acid and lactate dehydrogenase of mice after swim were observed. Results The experiments indicated that complex bear gall agent could greatly increase the time of loaded-swimming and climbing Pole,increase the hepatic glycogen content and serum lactate dehydrogenase activity ,decrease serum urea nitrogen and blood lactic acid content in mice. Conclusion Complex bear gall agent had a significant anti-fatigue effect.

Objective To explore the clinical curative effect of cerebral angio spasm after aneurysm rupture subarachmoid hemorrhage by Fasudil, Methods The clinical data of cerebral angio spasm after aneurysm rupture subarachnoid hemorrhage were retrospectively analyzed, which was divided into detection group and control group.Results The GCS score of detection group was better than control group;the average blood flow rate of arteria cerebri media after curing in detection group the difference had statistical significance( all P ＜0. 05 ). The mutilation rate、rate of death of detection group were lower than control goup, the difference had statistical significance ( P ＜ 0. 05 ).Conclusion The clinical curative effect was good of cerebral angio spasm after aneurysm rupture subarachnoid hemorrhage by Fasudil, and prognosis was good.

Objective To investigate the clinical manifestation characteristics of imaging,increase the diagnosis and treatment level of top of the basilar artery syndrome(TOBS). Methods Retrospective analysis of 21 clinical data with TOBS was carried out. Results More of cases were acute or subacute onset, the most common initial symptoms of vertigo, the clinical manifestation comprised unconsciousness, dismovement of the eyeballs and abnormality of the pupils. Imaging showed the feature of the TOBS was infarction in both sides of the midbrain and thalamencephalon, and multiple lesions exist. Conclusion The clinical manifestation of.TOBS were diverse, and only by grasping the characteristics of the TOBS raising awareness ,early diagnosis,standardized treatment and improving prognosis would be possibe.

Objective To observe and compare the changes of Intermedin's contents in plasma and bron-choalveolar lavage fluid (BALF) in rats with hypoxic pulmonary hypertension. Methods male Wistar rats were ran-domly divided into control group and 1,2 and 3 weeks hypoxia group. Intermedin's contents in plasma and bronchoal-veolar lavage fluid were measured by radioimmunoassay. Results Intermedin's contents in plasma and bronchoalveo-lar lavage fluid were markedly increaseded compared with control group. Meanwhile transformational trend is consist-ent between plasma and bronchoalveolar lavage. Conclusions Intermedin's contents in plasma and bronchoalveolar lavage increase ,which shows that there is protection and moderation to hypoxic pulmonary hypertension.

Objective To evaluate the curved cutter stapler in the anus-preserving surgery of low rectal cancer. Methods To retrospectively analyse the clinical data of the application of the Curved Cutter Stapler in the anus-preserving surgery of low rectal cancer from 2006 to 2008. Results All the eases of patients with low rectal cancer received the anus-preserving surgery,one of them occurred in sub-clinical small fistula who recovered by con-servative treatment,no anastomofic leakage and no local recurrence occurred,two patients were died in 12,14 months after surgery. Conclusion The Curved Cutter Stapler has an advangtageous position in the anus-preserving surgery of low rectal cancer, can increase the rate of the anus-preserving.

Objective To evaluate the clinical value of serum procalcitonin (PCT) in the diagnosis of bacte-rial infections in the critically ill patients. Methods A loud d 100 cases of critical patients were divided into bacteri-al infection group(56 cases) and non-bacterial infection group(44 cases). Serum PCT was measured by immunolu-minometric assay. Results The concentration of PCT in bacterial infection group(21.54 ±5.72) μg/L, was signifi-cantly higher than non-bacterial infection group (11. 95±4. 58)μg/L (t =2.291,P<0.05);The APACHE Ⅲ score of bacterial infection group(62. 44 ± 19. 55) cent was significantly higher than non-bacterial infection group(44. 56 ± 25. 88) cent(t = 2. 195 ,P < 0. 05). The concentration of PCT of 1.0μg/L and 2. 0 p.g/L compared to the former sensitivity (96. 5) % higher than the latter (55.2) % (X2 = 3. 94, P < 0. 05), the former specificity (41.7) % lower than the latter (95.8)% (X2 = 4. 02 ,P < 0. 05);1.5μg/L as a positive standard Youden index and the Agreement (83.0 % ,0. 65), were significantly higher than 1 μg/L and 2 μg/L(71.7%, 0. 38 ;73.6% ,0. 51) (X2 = 3.84, X2=3. 90,X2 = 3.992 = 3.91 ,P < 0. 05);The concentration of PCT in death group (38. 9 ±12. 6)μg/L was signifi-canfly higher than the survival group(11.8± 8. 3) μg/L(t =2. 398 ,P <0. 05). Conclusion Serum PCT has clinical values in the diagnosis and therapy of bacterial infections in the critical patients.

Objective To evaluate the application value of DSA diagnosis and interventional therapy in gas-trointestinal hemorrhage. Methods 36 cases of gastrointestinal hemorrhage used DSA examination, according to the reason and position,26 cases of the patients that were positive of DSA opacification utilized interventional therapy with different embolic agents or vasopressin peffusion. Results 26 cases of patients in 36 had gastrointestinal hemorrhage, 12 cases of patients in 16 that have extravasation of contrast media were hemostasis by treating with embolization ther-apy and vasopressin peffusion, hemorrhage of eholecyst and biliary tract after operation,the patients of small intestinal hemorrhage, gastroduodenal hemorrhage after the operation of pancreatic carcinoma were embolized with gelfoam ,PVAand/or colis were done. The stopped bleeding immediately oceured in 84. 6% (22/26). Conclusion DSA are more valuable methods for the diagnosis of gastrointestinal hemorrhage. Arterial embolization and/or perfusion of vasoconl-rictor substance for treatment of hemorrhage of digestive tract is safe, effec is reliable.

Objective To compare the antalgic effects of ropivacaine in various doses on brachial plexus nerves. Methods 87 patients undergoing upper arm surgery were enrolled in this study. The patients were unpremed-itated. The patients were randomized to receive ropivacaine of 0.30,0.25 or 0.20% (group Ⅰ,Ⅱ and Ⅲ) with mor-phine of 0.1mg/ml and Lidocaine of 10mg/ml. In order to analygesia of brachial plexus nerves,the rejecting of load dose is firstly 10ml,the total dose is 10ml/24h interval every time,the antalgic time is about 50 hours. To compare the antalgic effects of ropivacaine in various doses based on standard of VAS. Based on standard of Bromage to assess the situation of motor neuron blocking. Results According to standard of VAS in 6,12,24 and 48 hours after underwent surgery, the group Ⅲ is more effective than group Ⅰ and group Ⅱ ; according to standard of Bromage, the group Ⅰ is more effective than group Ⅱ and group Ⅲ. it has no adverse reactions to patients. Condusion 0. 25% of ropiva-eaine with morphine of 0.1mg/ml and lidocaine of 10mg/ml have obtained good antalgic effects for patients after un-dergoing upper arm surgery,it is fit for applying in clinic.

Objective To evaluate the influence of gestational diabetes mellitus(GDM) on the pregnancy outcome. Methods 84 cases with GDM by the clinical data of patients with GDM were analyzed retrospectively;84 cases were divided into untreated group(A group)42 cases and diet plus insulin treatment group(B group)45 cases, compared 2 groups of pregnancy outcome. Results In B group of pregnancy - induced hypertension, placental abrup-tion, polyhydranmios,when the middle class bleeding, puerperal infection (19.6%, 0%, 0%, 2.0%, 3.9%) were lower than A group (42.9%, 7.1% ,4.8% ,7.1%, 9.5%) (t=2.123,t =2.241,t =2.135,t =2. 312,t =2.309,P <0.05) ;In B group of gestational age(33.3%) was significantly lower than A group(23.8%) (χ2 = 3.95, P <0.05) ; In A group of cesarean section rate (69.0%) was significantly higher than the B group (22.2%) (χ2=4.01, P <0.05) ;in B group of stillbirth group (0%) was significantly lower than A group (9.5 %) (χ2= 7.89, P <0.01) ;In B group of birth weight was higher than A group(t = 2.209, P < 0.05), neonatal complications was lower than A group(χ2 =6.89,χ2 =7.09,χ2 =7.49,χ2=6.99,χ2 =7.29,χ2=7.39,P <0.01). Conclusion Pregnan-cy with diabetes is harmful to mother and infant. Diagnosing and treating the eases earlier can decrease the complica-tions of mother and infant as well as the death rate of perinatal fetus.
