Our experiments have shown that bee venom possesses effects of significantly increasing the fluidity of erythrocyte membrane,markedly decreasing the whole blood and plasma viscosities,accelerating erythrocyte microelectrophoresis speed and reducing erythrocyte rigidity index in rabbit. The results showed that bee venom can markedly change some of the parameters of hemorrheology,and possess certain effects in promoting blood circulation to remove blood stasis.

Objective To explore the conventional MRI,diffusion-weighted imaging (DWI)characteristics and the pathological basis of angiomatous meningioma.Methods The conventional MRI,DWI and pathological manifestations of 7 cases with angioma-tous meningioma confirmed by surgery and pathology were analyzed retrospectively.The apparent diffusion coefficient (ADC)value of the tumors and contralateral normal brain parenchyma were measured and compared with each other.Results Among the 7 ca-ses,5 cases were in the convexity of brain (4 cases in the frontal part and 1 case in the parietal part),and 2 cases in the parasella. 6 cases showed hypointense on T1 WI and hyperintense on T2 WI,and 1 case showed isointense on both T1 WI and T2 WI.The necro-sis within the tumor was seen in 2 cases.The flowing void phenomenon was seen in 6 cases.The significant peritumoral edema was seen in 5 cases on FLAIR.Significant enhancement on contrast-enhanced T1 WI was seen in all the cases.The average ADC value of the tumors (1.35×10 -3 mm2/s)was significently higher than that of the contralateral normal parenchyma (0.92 × 10 -3 mm2/s) (t=7.21,P <0.01).Mature vessel component was seen on pathological section in all the cases.For immunohistochemically analy-sis,the expression of vimentin (Vim)was positive in 6 cases and scattered positive in 1 case.The expression of epithelial membrane antigen (EMA)was positive in all the cases.Conclusion The MRI features of angiomatous meningioma are closely correlated with rich blood vessels.The ADC value of the tumor is higher than that of the contralateral parenchyma,which is helpful for the diagno-sis.

Partial hepatectomy (PH) is an effective method for the treatment of various liver tumors,and liver regeneration dysfunction is one of the most serious complications.Therefore,liver regeneration (LR) after PH is particularly important.In this paper,we reviewed the molecular mechanisms of LR including cellular factors,growth factors,metabolism and related signaling pathways,and reviewed the research progresses of the traditional Chinese medicine (TCM) in promoting liver regeneration.The aim was to further clarify the mechanism of the occurrence and development of LR,and to provide valuable information for the development of drugs for treating liver regeneration disorders.

Objective To investigate the clinicopathologic and immunohistochemical features of gastric stromal tumors.Methods A total of 105 cases with gastric stromal tumors were included in the study.The expression of cluster of differentiation 117 (CD117),cluster of differ entiation 34 (CD34),smooth muscle actin (SMA),S-100 protein and Ki-67 in gastric stromal tumors specimens was detected by immunohistochemistry.The clinico-pathologic features of gastric stromal tumors were also analyzed.Results Of 105 gastric stromal tumors specimens,90 were positive for CD117 [85.7 ％ (90/105)],98 positive for CD34 [93.3 ％ (98/105)],21 positive for SMA [20.4 ％ (21/105)],60 positive for Ki-67 [56.1％ (60/105)],13 positive for S-100 [12.4 ％ (13/105)].Conclusion Combined detection of CD117 and CD34 can improve the diagnostic accuracy of gastric stromal tumors.The expression of Ki-67 can be used as a prognostic parameter for gastric stromal tumors as it is correlated with tumor size,risk and mitotic.

Objective:To explore the relationship between coronary slow flow (CSF) and vascular inflammatory fac-tors .Methods :A total of 229 inpatients with normal coronary angiography (CAG) results were selected as research object .According to CAG TIMI flow and corrected TIMI frame count ,patients were divided into CSF group (n=102 ,no obvious lesion in epicardial coronary artery but coronary flow was slow ) and normal coronary group (n=127 ,completely normal epicardial coronary artery and blood flow ) .General clinical data were collected ,vascular inflammatory factors were measured and their relationship with CSF was analyzed .Results:Compared with normal coronary group ,there were significant rise in levels of high sensitive C reactive protein [ (1.41+0.72 ) mg/L vs . (2.82+0.58) mg/L] ,interleukin 1 [ (0.18 ± 0.05)μg/L vs .(0.26 ± 0.06)μg/L] and interleukin 6 [ (0.363 ± 0.016) ng/L vs .(0.465 ± 0.015) ng/L] in CSF group , P<0.05 all .Logistic regression analysis indicated that vas-cular inflammatory factors were risk factor for CSF occurrence (OR= 1.008 , P= 0.015 ) .Conclusion:Coronary flow velocity is closely related to vascular inflammatory factors .

OBJECTIVE:To evaluate the clinical efficacy of amlodipine in treatment of vasospastic angina systematically.METHODS:Literatures were retrieved from MEDLINE,EMBASE,CNKI,CBM and Wanfang database,etc.Data of literatures were analyzed using RevMan 4.2 software.RESULTS:3 RCTs were included in meta-analysis and 1 RCT was involved in descriptive analysis.Compared with diltiazem,amlodipine was similar to benidipine in reducing the incidence of cardiovascular events;there was no statistical significance[OR=0.79,95%CI(0.57,1.10),P=0.16].Effective rate of amlodipine was significantly higher than isosorbide dinitrate,there were statistical significance[OR=7.33,95%CI(1.47,36.66),P=0.02].Compared with placebo,amlodipine could reduce occurrence times of angina significantly.CONCLUSION:Amlodipine is effective in treatment of vasospastic angina and can reduce the incidence of cardiovascular events in patients with vasospastic angina.

Concepts and techniques of spinal fusion as a therapeutic modality may date back to the origins of spinal surgery. Spinal fusion has been considered as the standard treatment of progressive deformities,including instability,scoliosis and trauma. In this study,we shall attempt to define and review the bone graft materials,progress on the operative techniques,postoperative complications and related therapy,the latest dynamic fixation,and minimally invasive technique to lumbar spine fusion.

After a description of ISO11620:2014 , the international criteria for library performance assessment , how to enforce the construction of military academic libraries was systematically elaborated in terms of improving the quality and use of their resources and infrastructures, and reducing their construction cost.

Objective To explore the expression of cell apoptosis regulatory elements in esophageal canceration course. Methods 60 specimens of esophageal carcinoma and corresponding adjacent no cancerous tissue were detected quantitatively by propidium iodide(PI) stain and indirect immunofluorescence of fluorescein isothiocyanate(FITC) using flow cytometry(FCM) equipment. Results Expression of bcl-2 and c-FLIP in esophageal carcinoma was significantly higher, and Fadd, Caspase-8 and Caspase-3 were significantly lower than that in adjacent tissues (P <0.01). There was positive correlation between Fadd and Caspase-8 gene (P <0.01 or P <0.05). The expression of Fadd was positively correlated to Caspase-8. Comparing with normal epithelium and dysplasia tissue, DNA content and heteroploid cells were increased significantly in esophageal carcinoma. Conclusion During the esophageal canceration course, expressions of relevant cell apoptosis regulatory elements were abnormal. DNA content and heteroploid cells were increased significantly in esophageal carcinoma.
