ObjectiveTo determine the effect of telmisartan on the levels of serum adiponectin and C-reactive protein(hs-CRP)in elderly hypertensive patients with unstable angina pectoris. MethodsOne hundred and twenty elderly hypertensive patients with unstable angina pectoris were randomized into two groups, telmisartan(n=60) and perindopril(n=60) groups.The levels of hs-CRP,adiponectin, lipid factors, fasting plasma glucose (FPG), insulin and insulin sensitivity index (ISI) were measured before and 6 months after telmisartan and perindopril treatments.ResultsAt the end of 6 months, the telmisartan group showed more reduction in plasma levels of hs-CRP and more increment in serum adiponectin concentrations and ISI significantly. The frequency of cardiovascular events was significantly lower in the patients of the telmisartan group than that of the perindopril group.ConclusionsCompared with perindopril, telmisartan significantly decreases plasma levels of hs-CRP and increases serum adiponectin concentrations in elderly hypertensive patients with unstable angina pectoris. It also significantly decreases the frequency of cardiovascular events in these patients.

This study is to investigate the effects of paeoniflorin on cerebral blood flow and the balance of PGI2/TXA2 of rats with focal cerebral ischemia-reperfusion injury. A total of 72 SD rats (3) were randomly divided into 6 groups: sham operation group, cerebral ischemia-reperfusion model group (I/R gourp), low (10 mg.kg-1), middle (20 mg.kg-1) and high (40 mg.kg-1) doses of paeoniflorin groups and nimrnodipine group. Focal cerebral ischemia in rats was made by inserting a monofilament suture into internal carotid artery for 90 min and then reperfused for 24 h. The effects of paeoniflorin on neurological deficit scores and the infarction volume of brain were detected. Relative regional cerebral blood flow (rCBF) was continuously monitored over ischemic hemispheres by laser-Doppler flowmetry (LDF). The expression of COX-2 in hippocampal CAl region was estimated by immunohistochemistry and the contents of prostacyclin I2 (PGI2), thromboxane A2 (TXA2), and ratio of PGIJ2/TXA2 in serum were measured by ELISA kits. Paeoniflorin significantly ameliorated neurological scores, reduced the infarction volume, and increased regional cerebral blood flow relative to the I/R group. In addition, paeoniflorin could inhibit COX-2 expression and the release of TXA2 and prevent the downregulation of PGI2 induced by I/R injury. The neuroprotective effects of paeoniflorin against focal cerebral ischemia-reperfusion rats might be attributed to improve the supply of injured hemisphere blood flow and adjust the balance between PGI2/TXA2.

Objective To investigate the association between prodromal headache and the propensity of rebleeding after aneurysmal subarachnoid hemorrhage.Method Prodromal headache was defined as a sudden attack of severe headache lasting at least one hour with or without accompanying symptoms,not leading to a diagnosis of SAH 4 weeks before the confirmation of subarachnoid hemorrhage.Two hundred and nine patients with aneurymal subarachnoid hemorrhage were enrolled in this research.Age,gender,Hunt-Hess grade,D-dimer, (FBG),site and number of aneurysms and prodromal headache were recorded.Patients were divided into rebleeding group and non-rebleeding group.Comparing the above survey components between two groups was carried out by using case control study method.Age,aneurysm number,D-dimer and fibrinogen of the two groups were analyzed by t test.Prodromal headache,gender,site of aneurysms were analyzed by chi square test.Hunt- Hess grade was analyzed by rank test.Results Twenty-two(10.5%)patients had rebleeding.In the rebleeding group,10 patients(45.5%)had prodromal headache,while in the non-rebleeding group(n=187),21 patients (11.2%)had prodromal headache.Patients with prodromal headache had greater propensity of rebleeding compared with those without prodromal headache(P

The genes of maltooligosyl trehalose synthase (MTSase) and maltooligosyl trehalose tetrahydrolase(MTHase) from Sulfolobus solfataricus ATCC 35092 were amplified using PCR. The expression plasmids, pTrc99a-MTSase and pTrc99a-MTHase, were constructed by inserting these two DNA fragments into E. coli expression vector pTrc99a. The specific activity of MTSase and MTHase in E. coli BL21(DE3) at optimal fermentation conditions reached 31.3U/g (wet cell) and 403U/g (wet cell), respectively. The biotransformation of partially hydrolyzed starch to trehalose catalyzed by MTSase and MTHase was carried out at 75℃ and pH 5.0. The highest yield of trehalose (ca. 53.6%) was gained when the original starch concentration was 15%(w/v) and the DE value was 10.

This paper is discussed about course system construction of Microbiology, teaching method, in- struction means and experimental teaching mode. Teaching practice indicated that reform the pattern of Mi- crobiology educational mode can stimulate students’ interest in studying the course, cultivate their inde- pendent ability to solve questions, develop their creative thinking. It is an important way to train high-caliber talents.

Objective The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hardening agent localization.Methods From December 2010 to January 2012,27 patients with 29 solitary pulmonary nodules who had undergone CT-guided hardening agent localization and video-assisted thoracoscopic surgery (VATS) were studied.Results All cases were underwent CT-guided hardening agent localization successfully,and no patient had serious complication that required any intervention.The diameter of nodules ranged from 3 to 21 mm as measured by CT[mean (11.27 ± 6.32) mm].The distance between the center of nodule and visceral pleural ranged from 4 to 38 mm[mean (14.45 ± 4.32) mm].Conversion from VATS to thoracotomies was not necessary during the diagnostic resection procedure nodules.29 solitary pulmonary nodules underwent thoracoscopic wedge resection,and no intra-or postoperative mortality or morbidity was recorded.Conclusion CT-guided hardening agent localization before video-assisted thoracoscopic solitary pulmonary nodule resection is a safe and effective procedure for accurate diagnosis and resection of indeterminate solitary pulmonary nodules.

OBJECTIVETo discuss the effect of surgical staging and using craft bone with vancomycin for the treatment of calcaneal fractures.

METHODSFrom January 2006 to December 2012,13 patients with open calcaneal fractures were treated including 9 males and 4 females with an average of 35.2 years old ranging from 23 to 66. All cases were emergency cases. According to Sanders classification of calcaneal fractures, 2 cases were type II, 7 cases were type III, 4 cases were type IV. According to Gustilo-Anderson soft tissue injury classification, 8 cases were type II, 2 cases were type III A, 2 cases were type III B, 1 case were type III C. Firstly a thorough debridement or VSD procedures were applied,secondly calcaneal fracture were treated with open reduction, plate fixation and bone graft complex with antibiotics. Based on clinical examination, radiographic evaluation, and American Foot and Ankle Surgery Society (AOFAS), ankle function were evaluated after operation.

RESULTSOpen wounds were headed after dressing and repairing,, lateral calcaneal wound were healed during the first period. All patients were followed up for 6 to 36 months (means 14.5 months). Fracture healing time was 14 to 20 weeks (means 16.2 weeks). Last follow-up AOFAS ankle-hindfoot score was (80.0 +/- 7.4) ranging from 55 to 95.

CONCLUSIONFor patients with open fractures, through reasonable clinical evaluation, staging operation, using bone graft with antibiotics can reduce the incidence of postoperative wound infection and promote fracture healing.
