Dried roots and rhizomes of Salvia miltiorrhiza (Danshen) are among the most commonly used traditional Chinese medicines in clinic. The material basis for its efficacy mainly includes hydrophobic tanshinones and hydrophilic salvianolic acids. The traditional effects of Danshen are "removing stasis and relieving pain, activating blood to promote menstruation, clearing heart fire and tranquilization". According to modern pharmacological studies, Danshen and its main components have cardiovascular and cerebrovascular protective effect. Recent studies showed that Danshen and its main components also demonstrated protective effects on liver injury models induced by carbon tetrachloride, D-galactosamine, acetaminophen and alcohol. In this paper, the hepatoprotective effect and mechanism of Danshen were summarized and studied.

Post-stroke depression(PSD) is one of the most common complications after stroke,and seriously influenced the quality of life of hemiplegic patients.The article would review the associated factors and mechanism of PSD.

OBJECTIVETo summarize the method and experience of cardiopulmonary bypass (CPB) with vacuum-assisted venous drainage technology (VAVD) in the minimally invasive cardiac surgery (MICS).

METHODS35 cases of patients undergoing MICS were achieved femoral arterial cannula and femoral venous cannula. During the course of the CPB, we used the VAVD technology. At the same time, we selected 35 cases as control group.The time of the CPB, mechanical ventilation and ICU, and the amount of the urine, blood products, and chest drainage were recorded.

RESULTSThe time of mechanical ventilation and ICU staying, the volume of the blood products and the volume drainage within 48 h postoperatively in the MICS group were significantly shorter and less than that in control group (P < 0.05).

CONCLUSIONThe use of VAVD in the MICS can increase the vena cava drainage effectively, and ensure the surgery safe and successful.

OBJECTIVETo study the relationship between collgen (Col) IV, VEGF secreted by the tumor cells and vasculogenic mimicry (VM).

METHODS158 bi-phase differential malignant tumor specimens were alloted and made into tissue microarray. These tissue microarray sections were stained with CD31, periodic acid-Schiff (PAS) and Col IV. Subsequently, distributive trait of Col IV and the difference of VEGF expression were analyzed.

RESULTSThe basement membrane of VM was PAS and Col IV positive. The expression of VEGF in bi-phase differential malignant tumor with VM was less than that in those without VM. The difference of VEGF expression in malignant melanoma and alveolar rhabdomyosarcoma was significant (P < 0.05).

CONCLUSIONCollgen IV and periodic acid-Schiff positive material take part in constructing the basement membrane of vasculogenic mimicry. The difference of the VEGF expression proves that vasculogenic mimicry can sustain the tumor blood supply.

UNLABELLEDOBJECTIVE To assess the efficacy of concurrent chemoradiation with paclitaxel and platinum and external irradiation, and to compare the effect of extensive regional field irradiation with conventional local field irradiation for locally advanced esophageal cancer.

METHODSFrom Oct. 2000 to Jan. 2006, 89 patients with locally advanced esophageal cancer were registered in this study. All patients were inoperable or refused to undergo operation. Patients were divided into two groups: extensive regional field group (51 patients) and conventional field group (38 patients). Patients received radiotherapy at a total dose of 60 Gy in 30 fractions within 7 weeks,and concurrent paclitaxel 125 mg/m2 on D1, cisplatin 20 mg/m2 on D1-D3, or oxaliplatin 130 mg/m2 on D2 in the fist and fourth week of external radiation.

RESULTSOf these patients, 87.6% completed the treatment regimen with a response rate of 75.5% and 66.7% in the extensive regional field group and conventional field group, respectively. Grade 3 or severe toxicities of leucopenia (33.3% vs. 23.7%), thrombocytopenia (76.0% vs. 2.6%), and esophagitis (17.7% vs. 26.3%) were observed in extensive regional field group and conventional field group, respectively. Major late toxic effect was lung fibrosis. There were no statistically significant differences in the incidence of the toxicity profile between two groups. The overall 3-year survival rates was 32.8%, and the overall 3-year recurrence and metastasis-free survival rates was 34.5%. The overall 3-year locoregional control rate was 44.0%. No significant difference was found between two groups in the 3-year survival (38.2% % vs. 28.1%, P = 0.59). For the patients with stage II and stage III cancers who completed the planned treatment, large regional field radiotherapy significantly improved the 3-year survival (57.3% vs. 22.2% , P = 0.03) or 3-year recurrent and metastasis-free survival (55.5% vs. 23.0%, P = 0.03) or 3-year locoregional control (65.9% vs. 30.2%, P = 0.02) than conventional field radiotherapy.

CONCLUSIONhistorical results, the combination of paclitaxel/platinum and radiation in this study can improve the survival for locally advanced esophageal, and the side effect is well tolerated. Compared with the conventional field group, concurrent chemoradiotherapy with the large regional field can significantly improve 3-year survival and locoregional control for stage II or stage III esophageal cancer.

These active components and monomes inhibit thrombosis aimed directly at activation, adhesiveness and aggregation of platelet, thus preventing and curing ischemic cardiovascular and cerebrovascular diseases. Here we summarized the effect of active components and monomes of the traditional Chinese medicine targeted platelet on ischemic cardiovascular and cerebrovascular diseases, to provide references for drug investigation and clinical application.

Objective To evaluate the quality of the portal images acquired by computed radiography(CR)system and conventional screen-film system,respectively.Methods imaging plates (IP)and X-ray films of a home-devised lead phantom with a leakage of 6.45% were acquired,and modulation transfer function(MTF)curves of the both images were measured using edge method.Portal images of 40 nasopharyngeal cancer patients were acquired by IP and screen-film system respectively.Two doctors with similar experience evaluated the damage degree of petrosa] bone,the receiver operating characteristic(ROC)curve of CR images and general images were drawn according to two doctors evaluation results.Results The identification frequency of CR system and screen-film system were 1.159 and 0.806 Lp/mm respectively.For doctor one,the area under ROC curve of CR images and general images were 0.802 and 0.742 respectively.For doctor two,the area under ROC curve of CR images and general images were 0.751 and 0.600 respectively.The MTF curve and ROC curve of CR are both better than those of screen-film system.Conclusion The image quality of CR portal imaging is much better than that of screen-film system.The utility of CR in linear accelerator for portal imaging is promising in clinic.
