Complement-induced polymorphonuclearcytes (PMN) aggregate in microvasculature of vital organs, produce microemboli, and block microcirculation blood flow. Activated PMN release oxygen free radicals, prostaglandins and proteases, in turn, damage endothelial and parenchyma cells. This is an important factor in pathogenesis of multiple system organ failure. We have found that Sinomeuine and Sodium Ferulate prevented PMN aggregation induced by activated complement. Adding the drugs into PMN suspension treated with cytochalasin B, the zymosan activated plasma, PMN aggregation was prevented. The changes of light transmission were smaller than those of control without drugs recorded with platelet aggregometer. The 50% of PMN aggregation inhibition with Sinomeuine was 0.76mg/ml (1.gmmol/L), and 0.82mg/ml (3.8mmol/L) with Sodium Ferulate.

ObjectiveTo evaluate the retinal function with central serous chorioretinopathy (CSC) and the fellow eyes (mf-ERG).MethodsTwenty patients (40 eyes) with unilateral CSC, diagnosed by fluorescein angiography, were examined on each eye of the patients by mf-ERG multifocal electroretinography. The patients aged from 31 to 53 (13 men, 7 women; mean age, 41 years), and the CSC eyes had visual acuities of 0.2 to 0.8. None of the patients had significant abnormality in the fellow eyes with visual acuities of 0.8 to 1.5. Twenty-four healthy people (29 normal eyes with visual acuities of 1.0 and more and without any retinal diseases) were studied simultaneously as the normal control. The stimulus matrix of 61 hexagonal elements were grouped into 5 concentric rings from the fovea outward to 30? of the degree of visual field. The first-order responses of mf-ERG were recorded. The first negative wave (N 1-wave) and positive wave (P-wave) of the mf-ERG were measured. Amplitude intensities and latechies for the two configurations were calculated and compared.ResultsCompared with the control eyes, the responses were not only depressed severely in P 1- and N 1-wave amplitude intensities in the ring 1~3 in the CSC eyes with CSC (P0.05). There were no significant differences in N 1- and P 1-wave latencies in 5 concentric rings among the control eyes, the fellow eyes or the CSC eyes.ConclusionsCSC is a kind of macular disease involving both eyes. It may cause the decrease of retinal function in macular area of CSC eyes and also influence the retinal function in macular area of the fellow eyes. mf-ERG is a sensitive way in examining visual function.

Objective To discuss the early diagnosis of severe perioperative biliary infection complicated with DIC and efficacy of comprehensive treatment for it. Methods Comprehensive treat-ment was conducted in 21 patients who had intensive biliary infection complicated with DIC. The he-moglutination function was monitored before and after treatment. Results Of the 21 patients, 19 were cured and 2 dead. The curative rated was 90.5 %. The hemorrhage tendency was controlled, abdomi-nal bleeding stopped, prothrombin time (PT) obviously reduced, content of fibrinogen (Fbg)in-creased, level of D-dimer and FDPs obviously dropped. Conclusion The patients who have biliary in-fection in the perioperative period are easy to suffer from DIC and the mortality is high. Early diagno-sis and comprehensive therapy, especially the application of the cryofibrinogen and heparin, are very important.

Objective To compare fentanyl and sufentanil in total intravenous anesthesia for liver resection. Methods 100 patients undergoing liver resection were randomly received either sufentanil (group S, n = 50) anesthesia or fentanyl (group C, n = 50). Hemodynamic variables, time to spontaneous eye opening and extubation were recorded. VAS-scale was used to assess postoperative pain. The incidence of nausea & vomiting, agitation and respiratory depression was recorded and compared. Results Patients in group S had a more stable hemodynamic variables, and the incidence of postoperative pain (VAS: group S 4. 2± 1.1, group C 6. 1 ± 1.2), agitation (group S 2 cases, group C 11 cases) and respiratory depression (group S 1 case, group C 5 cases)was lower. Conclusions Both sufentanil and fentanyl were safe and efficacious in total intravenous anesthesia for liver resection. Compared with fentanyl, Sufentanil had higher hemodynamic stability, and lower incidence of postoperative pain, respiratory depression and agitation.

Objective To study the neuroprotective effect of sevoflurane on controlled hypotension in patients with coronary heart disease undergoing craniocerebral surgery. Methods Twenty-six patients with coronary heart disease undergoing craniocerebral surgery were randomly divided into two groups,receiving either inhaled 2%-5%sevoflurane plus intravenous sodium nitroprusside (treatment group,n=13) or intravenous sodium nitroprusside 3-8 μg·kg-1 alone (contorl group,n=13) for blood pressure control. The hemodynamic changes were recorded during the operation. Patient satisfaction with surgeons and the duration hospital stay after surgery were recorded. The levels of cardiac troponin I (TNI),creatine kinase-MB (CK-MBM),neuron specific enolase ( NSE) and S100 calcium binding proteinβ( S-100βprotein) in serum were detected at one day pre-operation,the end of the operation,and one day post-operation. Results The duration of hospital stay after surgery was significantly shortened in treatment group [(20. 3±3. 8) versus (23. 9±4. 6) d,P<0. 05) compared with control group. The average heart rate significantly decreased, patient satisfaction significantly increased, and serum levels of NSE and S-100β protein one day post-operation significantly decreased as compared to control group (all P<0. 05). Compared with the day before operation,serum levels of NSE and S-100βprotein in the two groups increased significantly at the end of surgery (P<0. 05),and the levels of TNI,CK-MBM,NSE and S-100βsignificantly elevated one day post-operation (P<0. 05). Compared with the end of operation,serum levels of NSE and S-100βin contorl group incarcerated remarkably (P<0. 05) Conclusion Sevoflurane plays an important neuroprotective role,as evidenced by improving patients' satisfaction,reducing hospital stay after surgery,and maintaining the balance of myocardial oxygen delivery and consumption in craniocerebral surgery patients with coronary heart disease during controlled hypotension. However,it can not prevent postoperative myocardial injury in these patients.

Objective To investigate the protective effect and it's possible mechanism of Tanshinone ⅡA in radiation-induced pulmonary fibrosis.Methods Having the right hemithorax of female Wistar rats irradiated(30?Gy) in 10 fractions within 14 days by 6 ?MV photons,the radiation-induced pulmonary fibrosis animal model was established.In the treatment group,sodium Tanshinone ⅡA sulfonate(15?mg/kg) was given by intraperitoneal injection 1 hour before each fraction of irradiation.Five months after irradiation,the difference of the histopathological changes,the hydroxyproline content and expression of TGF-?1 between the radiation alone group,tanshinone plus radiation and control group were analyzed by HE stain,Massion stain,immunohistochemical methor and reverse transcriptase polymerase chain reaction(RT-PCR) method.Results The histopathological comparison revealed the protective effect of Tanshinone ⅡA.The content of hydroxyproline was(21.99?3.96),((38.25?)(7.18)),(28.94?4.29)??g/g in the control group,radiation alone group and radiation plus Tanshinone ⅡA.The expression of TGF-?1(mRNA and protein) was reduced by Tanshinone ⅡA.Pathological changes of the pulmonary fibrosis was reduced by Tanshinone ⅡA yet.Conclusions Our study shows that Tanshinone ⅡA can inhibit radiation-induced pulmonary fibrosis,and the possible mechanism of its may be made possible through down-regulating the expression of TGF-?1 in the irritated lung tissue.
