Objective To measure anatomical parameter of internal carotid artery in petrous bone, and provide anatomical basis for operations Methods The anatomical study of the internal carotid artery (ICA) in petrous bone and related landmarks was studied in 15 adult cadaver brain specimens under the microscope Results The petrous segment of the ICA can be divided into ascending,bend and horizontal portion The great superficial petrous nerve was the best landmark through which the petrous segment of ICA can be exposed in operations. Conclusions If we are familiar with the anatomy of the petrous segment of the ICA and related landmarks,the petrous segment of the ICA can be protected very well in operations with less complications and better prognosis.

The methods and technology of immunopharmacology for Chinese Materia Medica have been progressing rapidly in recent years. The regulation of Chinese Materia Medica on the activity of cytokine and effector cells is reviewed in this article. Many clinical studies indicate that Chinese Materia Medica can regulate the production and activity of IFN, ILs, TNF, etc., and affect the cytotoxieity of NK. LAK, CTL, etc. The immunopharmcological research of Chinese Materia Medica in molecular and cellular levels is useful for explaining the mechanism of whole regulation and two-way regulation depending on the function of the body. In this article, the relations between quantity and effect, the study in vivo and in vitro, and the whole drug and its component are also reviewed.

Objective To isolate and identify the aseites-derived exosomes from patients with ovarian epithelial carcinoma,and explore the relationship between exosomes and the prognosis of ovarian epithelial carcinoma.Methods Ascites-derived egosomes were isolated by ultraeentrifugation on sucrose and D2O gradients from 41 ovarian epithelial carcinoma patients,and identified by transmission electron microscope and western blot analyses.Ascites-derived exosomes were evaluated for effect on prognosis of ovarian epithelial carcinoma.Resulls Exosomes were isolated and purified from the ascites in 85% (35/41)of ovarian epithelial carcinoma patients;major histocompability complex-I(MHC-I)could be detected in 100%(35/35)of the aseites-derived exosomes samples,heat shock protein-70(Hsp70)in 91%(32/35),and CD81 in 86%(30/35).The patients with positive ascites-derived exosomes had no significant difference in age,pathological type and the degree of differentiation of tumor,surgical-pathological staging,the optimal operation and the responsibility to chemotherapy(P>0.05).The patients with positive ascites-derived exosomes,the reduction of CA125 level after cytoreduetive surgery was(66±27)%,which was more than that of the patients without ascites-derived exosomes(37±86)%and all the whole patients not considering the condition of exosomes(61±44)%(P<0.01),and there were also no difference whether or no optimal operation ration(P<0.01).Conclusions There are ascites-derived exosomes in ascites from most patients with ovarian epithelial carcinoma.While the relationship between exosomes and prognosis of ovarian epithelial carcinoma needs further research.

Objective: To obtain anatomical parameters for surgery of the cavernous sinus. Methods:The anatomical study of nerves and triangles of the cavernous sinous was made in 15 adult cadaver brians by microanatomical methods. Results: Ten triangles of the cavernous sinus and 3rd cranial nerve, 4th cranial nerve in each cavernous sinus were studied. It was discovered that almost all content could be shown through Hakuba triangle and Parkinson triangle. Conclusion: The anatomical parameters of cavernous sinus is obtained, it is useful for surgical treatment of cavernous diseases. [

OBJECTIVE To introduce the characteristic and advantage of a kind of therapeutic method for chronic tibial osteomyelitis by cleaning the focus,iodophor sterilizing and then bone grafting at some selective time.METHODS Ribbon-gauze immersed with iodophor was used for tamponade and constant hydropathic compress after a surgery of debridement,then intramedullary bone grafting was performed.RESULTS This treating manner was applied in 18 patients with chronic tibial osteomyelitis and 17 cases(94.4%) healed,1 case recrudesced.CONCLUSIONS It is reliable for this kind of therapeutic method by debriding the focus,followed by an open and constant hydropathic compress with iodophor,and then grafting bone,which may promote the healing rate of chronic tibial osteomyelitis.

Electrophysiological monitoring of the activity of the penile sympathetic skin responses (PSSR) in healthy men and patients with erectile dysfunction (ED). Methods: PSSR were recorded from the skin of penis with disk electrodes at the time of electric stimulation of left median nerves. Results: PSSR were recorded from all the healthy men and almost all the patients. In healthy men the latency of P0, the latency of N1, the duration of N1 and the amplitude of N1 were 1249 ± 111 ms, 2239 ± 286 ms, 1832 ± 505 ms and 470 μV (median), respectively. In ED patients the latency of P0, the latency of N1, the duration of N1 and the amplitude of N1 were 1467 ± 183 ms ( P ＜ 0.01), 2561±453 ms (P ＜0.05), 2560±861 ms (P ＜0.01) and 91 μV (P ＜0.01), respectively. The normal latency of P0 was less than 1471 ms. The normal amplitude of N1 was more than 235 μV. According to this normal value, of 20 patients 11 showed longer latency of P0, and 14 showed lower amplitude of N1 as compared with those of normal subjects.Conclusion: PSSR can be used as an electrophysiological method in assisting the diagnosis of ED.

Objective To investigate the association between carotid-femoral pulse wave velocity (cfPWV) and composition of the ascending aorta in patients with coronary heart disease (CAD),Methods The study population comprised 60 consecutive CAD patients who underwent coronary artery bypass graft (CABG) surgery in Qilu Hospital of Shandong University.cfPWV vas measured using an automatic device (Complior,Artech,France).A quantitative study was conducted on ascending aorta specimens by histological observation (Masson staining and weigert's resorcin-fuchsin staining) and computer image analysis.Bivariate analyses were performed to study the association between composition of the ascending aortic media and cfPWV.Results cfPWV of the CAD patients was higher (14.2±2.0) m/s than that of the normal subjects.On Masson's-stained specimen slides,disorganization of smooth muscle and focal accumulations of collagen (44.1 ± 3.9)％ were visible alongthe medial aorta of the CAD patients.Weigert's-stained cross sections of the ascending aortic media in CAD patients frequently exhibited focal breakdown or discontinuous segments of elastic fibers(18.4±3.2)％,cfPWV had a positive correlation with relative contents of collagen in the ascending aorta(r=0.68,P＜0.01)and a negative correlation vith relative contents of elastin in the ascending aorta (r=-0.59,P＜0.01),but no relation with relative contents of smooth muscle(r=0.01,P＞0.05).Conclusions The reduced aortic elasticity in CAD patients can be partly ascribed to decreased elastin,increased collagen,and their disorganization.cfPWV can reflect the quantitative changes of collagen and elastin in the ascending aortic media in CAD patients.

Aim To amplify P30 gene and express P30 fusion with GST Methods P30 gene was smplified from T. gondii chromosomal DNA and ligated to pGEM-T and pGEX-4T-1. Screening-positive recombinants were induced for expression, which was subsequently detected by WB Results P30 gene was amplified and GST-fusion was confirmed by rabbit antiT. gondii serum. Conclusions The construction of pGEM-T-P30 and pGEX-4T-1-P30, together with the recombinant protein would lay a base for further investigation of P30 at a molecule-level and application to diagnosis and vaccination
