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.

Objective To investigate whether there is a correlation of serum interleukin 18 (IL 18) and nitric oxide (NO) with Fulminant Hepatic Failure(FHF) and the effect of N acetylcysteine (NAC) on IL 18 and NO levels. Methods The level expression and dynamic changes of serum IL 18 and NO in 65 FHF patients serum were measured by ELISA. IL 18 and NO and their expression levels were observed comparatively in NAC treatment group (29 cases) and composite treatment group (36 cases). Results Serum IL 18 and NO concentrations in patients with FHF in both groups (NAC and Combination) were significantly higher than the control ( P

Objective To investigate the preventative effect of perioperative intervention to lower extremity deep venous thrombosis (DVT) after gynecologic surgery. Methods The 1062 patients, who received gynecologic surgery during 2007 June to 2008 June, were derided into intervention and nonintervention groups randomizely. According to the risk factors of DVT, the patients in intervention group were divided into 4 subgroups: low, mid, high and extremely high rise Each group had its own preventive measures. If patients had spontaneous pain, tenderness and swelling, positivity of Neuhof or Homan syndrome, and extension of one low extremity superficial vein, the low extremity color Doppler ultrasound would be carried out immediately. The ultrasound would also be routinely carried out in the high and extremely high risk groups in intervention group after 2 and 7 days after surgery. A prospective study was carried out investigating incidence of DVT and coagulation function perioperation. The vein blood samples were taken at in a week before surgery and 48 hours post-operation. Results The incidence of DVT of intervention group was 1.10% (6/546), and in nonintervention group, the incidence was 3.29% (17/ 516). There was significant difference between two groups (P<0.05). The incidence of DVT in extremely high risk subgroup was 21.05% (4/19), which was significantly higher than that of low(0), mid(0) and high risk groups[2.13% (2/94), P<0.05]. D-dimer, antithrombin-Ⅲ(AT-Ⅲ) post-operation were all higher than that pre-operation in the two groups, but there was no significant difference (P>0.05). The indexes of coagulation system, such as blood platelet count, prothrombin time (PT), active partial throraboplastin time (APTT), fibrinogen (Fbg), thrombin time (TT), tissue-plasminogen activator (t-PA), plasminogen activator inhibitor(PAI), were not significantly changed perioperation (P>0.05 in all pre-or post-operation indexes). Conclusions Perioperative intervention measurement according to different risk of DVT could cut down the incidence of DVT. DVT preventive intervention is suggested to high and extremely high risk people.

OBJECTIVETo observe the clinical effects and the serous estradiol change of patients with menopause syndrome using Xianling Gubao capsules for treatment.
METHOD110 patients with manopause syndrome who were diagnosized by clinic index were recruited for the study. They were divided into two groups randomly. The treatment group were dealed with Xianling Gubao capsules and the control group with placebo of starch capsules for 8 weeks. The menopausal Kupperman index was used to assess change in menopausal symptoms before and after treatment. At the same time, serous estradiol and the thickness of uterine endometrium was evaluated.
RESULTThe Kupperman index were improved apparently in treatment group after treatment (P < 0.01). The serous estradiol level of treatment group was increased apparently after treatment (P < 0.05). However, There were no statistical deference in the thickness of uterine endometrium in the treatment and the control group before and after treatment.
CONCLUSIONThe treatment using Xianling Gubao capsules for patients with menopause syndrome could improve the clinic symptoms, increase the serous estradiol level, but do not increase the risk of endometrial hyperplasia.
