Objective To investigate the level of coronary endothelial injury and dysfunction, the jeopardy score of coronary artery lesion by angiography, and their correlations in patients with stable angina (SA) or unstable angina (UA). Methods The 20 patients with UA, 17 patients with SA and 18 patients excluding coronary heart disease (control) were studied. Blood samples were collected during percutaneous coronary intervention (PCI). To investigate the coronary endothelial injury and dysfunction, we measured the concentrations of nitric oxide (NO)? endothelin (ET) and the number of circulating endothelial cells (CEC) in coronary sinus blood. The jeopardy score for coronary artery lesion was evaluated according to the method by Califf. Results In angina patients, especially in UA patients, NO concentration in coronary sinus blood was lower, while ET concentration and CEC number were markedly higher than those in control group. The jeopardy scores showed no difference between UA and SA. The coronary endothelial injury and dysfunction showed a positive correlation with jeopardy scores. Conclusion The coronary endothelial injury and dysfunction is not only the initiation factor, but may play a key role in the progression of atherosclerosis and coronary heart disease. Coronary angiography combined with detection of coronary endothelial injury and dysfunction may better describe the lesion of coronary artery, and evaluate the prognosis of patients with coronary heart disease.

Objective To summarize our experience with combined cardiac pacing and beta-blocker therapy in patients with long-QT syndrome. Methods Nine patients with long-QT syndrome were treated with Propranolol. Its effectiveness was analyzed during matched periods before and after starting beta-blocker therapy. If sinus bradycardia, sinus arrest and atrioventricular occurred during the Propranolol treatment, DDD pacemaker were implanted. Results After initiation of beta-blockers, there was a significant reduction in the rate of cardiac events [(0.86?0.92) to (0.34?0.69) events per patient per year, P

Objective To explore the cyclase-associated protein 2 (CAP2) expression in hepatocellular carcinoma (HCC).Method The expression of CAP2 was determined by reverse transcription PCR,Western blot,and immunohistochemistry in normal liver,cirrhotic liver,and HCC.Results According to reverse transcription PCR and Western Blot,the level of CAP2 was up-regulated in HCC and was further up-regulated in progressed HCC than in early HCC.CAP2 expression was almost absent in normal and cirrhotic liver.The same results were seen in immunohistochemical examination.Also,CAP2 showed stronger expression in medium and poor-differentiated HCC than in well-differentiated HCC.Conclusion CAP2 is an up-regulated gene in HCC and may relate to the stages of hepatocarcinogenesis.Therefore,CAP2 could be used as a valuable molecular marker for HCC diagnosis in the future.

The ongoing health reform is bringing reforms of public hospitals under spotlight in China, attracting growing attention onto its progress and roadblocks. Probing into the "three steps" of public hospital system reform in Wuxi, this article analyzed such a reform in the city. It described the measures and initial outcomes gained in such fields as the hospital trusteeship reform, the separation of hospital regulation from its administration, and the hospital board system. Citing the case of Wuxi No. 2 People's hospital as an example, the authors introduced the innovative efforts made in hospital internal mechanism, management innovation, medical service model, hospital connotation construction, and talents cultivation.

Objective: To assay the content and stability of vitamin C(VC) in serum by a simple, specific method. Methods: Serum samples were extracted by metaphosphoric acid, and analyzed on a column C 18 of HPLC with DAD detector at 234 nm. Mobile phase was 100 mmol/L KH 2PO 4, pH3.00. The flow rate was 1 ml/min. Results: Under this condition, the retention time of VC was 5.76 min. The within run and between run reproducibilities tests were 0.42% and 2.11% respectively, and the recovery rate ranged from 82% to 88.5%. Stored at -70 ℃ and compared to that of its metaphosphoric acid extract, serum VC content was stable only for two days, and then decreased rapidly, whereas it did not decrease in metaphosphoric acid extract until the fifth day. Conclusion: A simple, sensitive and reliable method of HPLC with DAD detector is established for measuring VC in either serum or fruit, such as orange juice. VC should be determined immediately or should be extracted with metaphosphoric acid as soon as possible, then the extracts are kept at -70 ℃, and analysed within 5 d.

Objective To investigate the clinical application and surgical techniques of lateral-orbital keyhole approach to clip ruptured tiny aneurysms.Methods A retrospective analysis was performed on the clinical data of 56 patients with ruptured tiny aneurysms, including examination methods, imaging features, diagnosis and treatment process, and operation effect, which underwent lateral-orbital keyhole approach from January 2013 to April 2014.Results Among 56 patients with a total of 61 aneurysms(56 tiny aneurysms) was examined by CT angiography (CTA) and/or digital stubtraction angiography (DSA), all achieved successful clipping with a rupture rate of 16％(13 cases).Forty-two cases got a good recovery,8 cases owned the self-care ability, and 6 cases could carry out daily lives with help.There was no rebleeding and mortality, according to a 2-28 months' follow-up of 49 patients.Conclusion As a surgical approach for Willi'S cycle aneurysm,the lateralorbital approach is simple,rapid,minimally-invasive way.It is available in the clipping of ruptured tiny anterior communicating aneurysms.The option of operative time, perfect microdissection and exquisite intraoperative microinvasive operative skills, will be the key point of clipping aneurysms, preventing and controlling of intraoperative bleeding.

Aim To study the absorption mechanism of apigenin-7-O-glucronide, 3,4-Dihydroxycinnamic acid and chlorogenic acid in Erigeron breviscapus extract ( Ebe) by Caco-2 cell monolayer model. Methods The three active ingredients were quantified by UPLC-MS/MS method, and the effect of Ebe concentrations, conveying times, pH values and P-glycoprotein inhibi-tor on the transport of three active ingredients were also investigated. Results Apigenin-7-O-glucronide and chlorogenic acid in Caco-2 cell monolayer model were time-dependent and concentration-dependent. The 3, 4-Dihydroxycinnamic acid in Caco-2 cell uptake was concentration-saturate and P-glycoprotein inhibitor was involved in the uptake process. Conclusion The mechanism of apigenin-7-O-glucronide and chlorogenic acid absorption in cells is mainly through passive trans-port, and the absorption of 3, 4-Dihydroxycinnamic acid is mainly realized by the carrier transport.

Objective To investigate the clinicopathological significance of the expression of annexin A2 (ANXA2) in liver fibrosis and hepatocellular carcinoma (HCC).Methods The expression level of ANXA2 in normal liver,liver cirrhosis and HCC were examined by Western blot.The correlation between ANXA2 expression and clinicopathological parameters in liver fibrosis and HCC were analyzed by immunohistochemistry.Results Compared with the normal liver tissue,ANXA2 protein expression level increased significantly in HCC and liver cirrhosis,with the highest expression in HCC (P =0.000).There was significantly positive relationship between ANXA2 protein expression and stages for liver fibrosis (P ＜ 0.01).The expression of ANXA2 protein in HCC was closely associated with HBV infection,differentiation degree and the recurrence (P ＜ 0.05).In some cases,ANXA2-positive cancer cells were often dispersed in the periphery of cancer nodules and were adjacent to stromal cells.Conclusion Overexpression of ANXA2 may be involved in liver fibrosis and play a role in the development of HCC,indicating ANXA2 may serve as a diagnostic biomarker for liver fibrosis and tumor differentiation in HCC.
