BACKGROUND: Basic fibroblast growth factor (bFGF) possesses multiple functions such as promoting neuronal survival and growth of cell processes in vitro and antagonizing the toxicity of excitatory amino acids,thereby playing import roles in functional recovery of the central nervous system (CNS). But whether bFGF offers neuroprotection on ischemic brain tissues by modulating intracellular free calcium content remains unknown.OBJECTIVE: To explore the effect of bFGF on intracellular free Ca2+ in the neural cells in the event of focal cerebral ischemia-reperfusion (IR)injury.DESIGN: Randomized controlled study.SETTING: Department of Neurology of Second Hospital Affiliated to Zhengzhou University.MATERIALS: This study was conducted in the Laboratory of the Department of Neurology, Second Hospital Affiliated to Zhengzhou University between August and December 2003. Totally 24 SD were randomized into sham operation group, ischemic group, IR group and bFGF exposure group with 8 rats in each group.METHODS: Middle cerebral artery occlusion (MCAO) model was established in rats in IR group and bFGF exposure group by inducing arterial thrombosis with thread, which was not preformed in rats in the sham operation group. Rats in bFGF exposure group received intraperitoneal injection of 10 μg/kg bFGF immediately after ischemia,which was replaced by the same volume of physical saline in the other two groups. Free Ca2+ in brain cells was detected at 24 hours of IR.MAIN OUTCOME MEASURES: Free Ca2+ in the brain cells at 24hours of IR.RESULTS: All the 24 rats survived the experiment. Free Ca2+ in IR group was significantly higher than that of the sham operation group [(673.46±18.44) vs (224.71±10.58) nmol/L, F=1 329.06, P ＜ 0.01], and also significantly higher in bFGF exposure group [(378.37±21.08) nmol/L,F=1 329.06, P ＜ 0.01].CONCLUSION: Intracellular free calcium can be obviously depressed by bFGF following IR injury, which benefits cell membrane stability and help prevent intracellular Ca2+ overload.

Endothelial glycocalyx is a hairy-like structure covered the endothelial cell surface,which consists of multiple functional elements.It has been proved that glycocalyx can regulate vascular permeability,mediate shear-induced release of NO by endothelial cells,and exert wide array of vasculoprotective effects via inhibition of coagulation and leucocyte adhesion.Degradation of glycocalyx may be associated with many cardiovascular diseases.In this review,the relationship between the endothelial glycocalyx and cardiovascular disease will be discussed.

20 % . In both groups CH was induced with infusion of 0.01 % NTP at a rate 0.5-6.0 ?g?kg-1?min-1 to maintain MAP at 55-65 mm Hg. MAP, HR, CVP and CO were continuously monitored. Arterial lactate concentration was measured by enzyme assay. Arterial and mixed venous blood gases were analyzed, and oxygen delivery (DO2 ) and consumption (VO2) were calculated before AHH (T0) after AHH was performed (T1), 30 min after CH was induced (T2) and 30 min after termination of CH (T3) in group Ⅰ and in group Ⅱ before CH (T1), 30 min after induction of CH (T2) and 30 rain after termination of CH (T3 ) .ResultsIn group Ⅰ(AHH + CH) compared with the baseline values (T0 ) HR significantly decreased while CVP significantly increased after AHH (T1 ) ; cardiac output (CO) significantly increased after AHH (T1 ) and during CH (T2) while DO2 was significantly decreased after AHH (T1) and CH (T3 ) but arterial lactate concentration was significantly decreased during and after CH (T2, T3). In group Ⅱ (CH alone) compared with the baseline values (T1) HR significantly increased while CVP significantly decreased during and after CH (T2, T3 ) ; there was no significant change in CO and DO2 at T2 and T3 but arterial lactate concentration significantly increased during and after CH (T2, T3). There was significantly less blood loss during operation in group I than in group Ⅱ . ConclusionThere was tissue deoxygenation during and after deliberate hypotension as shown by increased arterial lactate concentration while AHH combined with CH can improve tissue perfusion and oxygenation. AHH can also maintain hemodynamic stability during CH.

AIM　Five Isoflavonoid glycosides were isolated from the pericarps of Sophora japonica L. and their structures were elucidated by chemical and spectral method as genistein 7,4′-di-O-β-D-glucoside(Ⅰ), sophorabio-side(Ⅱ), prunetin 4′-O-β-D-glucoside(Ⅲ), sophororicoside(Ⅳ) and genistin(Ⅴ). Among them, compounds Ⅰ, Ⅲ and Ⅴ were isolated from in S. japonica for the first time.

AIM: To study the effect of sphingosine 1-phosphate (S1P) on the increase in microvessel permeability induced by platelet activating factor (PAF). METHODS: The microvessel permeability was assessed by measuring hydraulic conductivity (Lp). To observe the effect of S1P and PAF on vascular endothelial-cadherin (VE-Cadherin), the microvessels were stained with immunofluorescence and examined by laser confocal microscopy. RESULTS: After giving PAF at concentration of 10 nmol/L, the Lp value of rat mesentery microvessel was significantly increased. However, after pretreatment with S1P, PAF did not give rise to a further significant change. The effect of PAF on microvascular endothelial cells could be seen: the formation of endothelial gap was induced, the microvascular fluorescence intensity significantly increased, a large number of fluorescent microspheres (FMs) distributed in the space among the endothelial cells. However, after pretreated with S1P, no obvious gap opening and the FMs accumulation were observed. Compared to normal control, no significant difference of the microvascular fluorescence intensity was found. CONCLUSION: PAF changes the structure of VE-Cadherin, leading to detachment of adherent junction, formation of intercellular gaps, which contributes to the increase in the permeability. S1P improves the increase in the microvessel permeability caused by PAF, which might be mediated by strengthening adherent junction and inhibiting the formation of endothelial gaps.

Objective To investigate the effection of Shenfu Injection (Ginseng-radix aconitum Injection)to the blood coagulation system and its prognosis in the patient of multiple trauma complicated with shock.Methods We prospectively studied 90 patients of multiple trauma complicated with shock,who came from the emergency center of the Second Affiliated Hospital of Medicine' s college of Zhe-Jiang University and emergency department of Lishui People' s Hospital from February 2007 to December 2011,and excluded those suffered with the dysfunction of coagulation system and uncontrolled ongoing bleeding before trauma.And then these eligible patients were randomly divided into two groups:treatment group ( 45 cases ) and control group (45 cases),the control group were received the routine treatment,the treatment group were received Shenfu Injection in early stage based on the routine treatment.The two groups were measured the platelet count (PLT),prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT),fibrinogen (FIB) before treatment and 3,7 days after treatment.Results The differences of the PLT,PT,APTT,TT,FIB between the treatment group and control group at 3,7 d after the treatment was statistically significant (P ＜ 0.05 ). Conclusions Shenfu Injection has positive regulation to the coagulation system in the patient of multiple trauma complicated with shock.

Aim To investigate the protective effects of sphingosine 1-phosphate ( S1 P ) postconditioning on hypoxia/reoxygenation( H/R) injury in human umbili-cal vein endothelial cells ( HUVEC ) and its mecha-nisms. Methods HUVECs cells were divided into five groups: normal ( control) group, S1P low concentra-tion group ( L ) , S1 P medium concentration group (M), S1P high concentration group ( H) and H/R group. MTT method was used to measure cell survival. Using flow cytometric analysis, the rate of cell apopto-sis was determined. The activities of total superoxide dismutase ( T-SOD) , copper/zinc superoxide dismuta-se ( CuZn-SOD ) , manganese superoxide dismutase ( Mn-SOD) activity, nitric oxide ( NO) and malondial-dehyde ( MDA ) content in cell culture medium were measured with colorimetry. Mitochondrial membrane potential in cells was observed with fluorescence micro-scope. Bax/Bcl-2, eNOS protein expression levels in HUVECs cells were observed with Western blot. Re-sults Compared with H/R group, S1P low, medium and high concentrations in the intervention group could significantly increase the cell survival rate after H/R injury, and increase activity of T-SOD, CuZn-SOD, Mn-SOD and decrease content of MDA. Moreover, S1 P could significantly increase NO content and in-crease eNOS protein expression, decrease apoptosis rate and inhibit the reduction of mitochondrial mem-brane potential. Conclusions S1P can decrease cell apoptosis rate of HUVECs after H/R injury with a cer-tain concentration dependence. The protection of S1P for cell apoptosis of HUVECs after H/R injury may be related to decreasing the intracellular MDA content and improving intracellular SOD activity, increasing mito-chondrial membrane potential and enhancing expres-sion of Bcl-2, anti-apoptotic protein.

Objective To study the therapeutic effect of EUS-guided biliary drainage (EUS-BD) on patients with malignant obstructive jaundice when ERCP failed.Methods From January 2014 to January 2016,all patients with malignant obstructive jaundice during hospitalization underwent EUS-guided biliary drainage (group A,36 cases) or PTCD treatment (group B,30 cases) by draw after failed ERCP.Operation success rate,liver function recovery time,complication rates,length of hospital stay and hospital costs were observed and compared.Results There was no significant difference in the operation success rates between two groups [94.44％ (34/36) VS 86.67％ (26/30),P＞0 05)].And there were significant differences in liver function recovery time (25.79± 6.48 d VS 30.24 ± 8.49 d),incidence of complications [5.56％ (2/36) VS 23.33％ (7/30)],length of hospital stay (21.54±4.73 d VS 25.68 ± 8.56 d) and hospitalization costs (23.5±8.4 thousand yuan VS 32.8±6.5 thousand yuan,P＜0.05).Conclusion EUS-guided biliary drainage could be the first option for its noninvasiveness and efficacy,when ERCP failed in patients with malignant obstructive jaundice.

Objective To evaluate the safety and diagnostic accuracy of preoperative endoscopic ultrasound-guid﹣ed fine-needle aspiration in patients with pancreatic cancer. Methods 256 patients with pancreatic cancer from Jan﹣uary 2010 to December 2014, 82 were considered resectable on the basis of cross-sectional imaging findings. Of these patients, 54 underwent EUS-FNA before surgery (FNA+group) and 28 underwent surgery without preoperative EUS-FNA (FNA- group), the diagnosis result of EUS-FNA and the survival time of the two groups were observed. Results All 54 lesions were visible on EUS, and all 54 attempts at FNA were technically successful. The diagnostic accuracy according to cytology and histology findings was 94.44 % (51/54) and 88.89% (48/54), respectively, and the total accuracy was 94.44 % (51/54). Two patients developed mild pancreatitis and two hemorrhage after EUS-FNA but were successfully treated by conservative therapy. No severe complications occurred after EUS-FNA. In the FNA+and FNA- groups, the median relapse-free survival (RFS) was 282 and 265 d, respectively (P>0.05), and the median overall survival (OS) was 568 and 557 d, respectively (P>0.05). RFS and OS were therefore not inferior in the FNA+group. These data indicate that the usage of EUS-FNA did not influence RFS or OS, nor did it increase the risk of other complications. Conclusions Preoperative EUS-FNA is a safe and accurate diagnostic method.
