The present study was designed to investigate the effects of mifepristone on apoptosis of the decidual tissue cells and apoptotic correlated gene Fas/FasL expression in human early gestational period. The extent of DNA fragmentation of apoptotic cells were assessed by using an in situ terminal transferase reaction to label free 3′ ends of the DNA.The expression of Fas, FasL in the deciduas was examined by in situ hybridization with cDNA probe and immunohistochemical staining with polyclonal antibodies, respectively. The results showed that there were evident apoptosis in decidual tissues at about 40 days of gestation. Fas and FasL were strongly expressed in these decidual tissues. At about 50 days of gestation, there were a few apoptotic cells in the decidual tissues. Expression of Fas, FasL decreased at the same time. More apoptotic cells were observed in decidual tissues after adiministration of Mifepristone (RU486) in about 50 days of gestation. Fas, FasL mRNA and protein were up regulated after administration of Mifepristone. The results suggested that the induction of apoptosis by Mifepristone in decidual tissues might be one of the major mechanisms with regards to contraceptive and antigestational effects of mifepristone. Fas pathway might participate in the process of decidua apoptosis induced by RU486.

Objective To explore the imaging characteristics of neurologic complications associated with the enterovirus 71 ( EV71 ) epidemic by analyzing 25 cases and reviewing the literature. Methods Twenty-five cases of hand-foot-mouth disease with neurologic complications during the recent EV71 outbreaks of Hainan province were studied for the clinical features and imaging findings, and literature were reviewed.Results In 5 cases, acute flaccid paralysis associated with EV71-infected hand-foot-mouth disease was related to the linear high signal in the spinal cord on sagittal images. Two cases showed symmetrical, welldefined hyperintense lesions in the spinal cord on T2WI transverse. Strong enhancement of the ventral horns and root was seen on the contrast-enhanced axial T1WI. In brainstem encephalitis, all lesions presented with significant hyperintensity on T2WI and hypointense on T1WI in the posterior portions of the medulla oblongata, midbrain, and pons. The manifestations of aseptic meningitis (AM) on MRI have no characteristics, but subdural effusion, meningeal enhancement and hydrocephalus can be the indirect signs of AM. Conclusions MRI is an effective method to investigate neurologic complications associated with the EV71 epidemic. Posterior portions of the medulla oblongata and pons, bilateral ventral horns of spinal involvement are characteristic findings of enteroviral encephalomyelitis.

Objective To explore the relationship between uric acid (UA) level and cognitive function in elderly patients with Parkinson,s disease (PD) and analyze the cognition related factors.Methods The clinical data of 60 elderly PD cases in our hospital from 2001 to 2009 were retrospectively analyzed. The 60 healthy people receiving medical examination in our hospital and matched by gender and age, were as control group. The information including gender, age, illness duration, Hoehn & Yahr stage (H-Y stage), serum UA level and Mini-Mental State Examination (MMSE) scale were recorded. Results The serum UA level was significantly lower in PD group than in control group [(262±53) μmol/L vs. (332±45) μmol/L, t=-6.724, P<0.001]. In PD group, the serum UA level was slightly higher in males than in females [(271 ±48) μmol/L vs.(254±39) μmol/L, t=3. 282, P=0. 058]. The serum UA level was significantly lower in male PD patients than in male controls [(353± 62) μmol/L, t=- 5. 625, P<0. 001], and was lower in female PD patients than in female controls [( 294 ± 59) μmol/L, t = - 4. 721, P = 0. 012]. There were no significant differences in serum UA level among different H-Y stage subgroups (P>0. 05), but the serum UA level was lower in different H-Y stage subgroups than in control group (F=22. 039, P<0. 01 ). There was no correlation between the UA level and the illness duration (r=0. 961, P>0.05).The MMSE score had significant difference between elderly PD group and control group (t= -3. 168,P<0. 001). In PD patients, the MMSE score was positively correlated with serum UA level (r=0. 789, P= 0. 000), and was negatively correlated with H-Y stage (r= - 0. 577, P = 0. 019 ), age (r= -0. 333, P=0. 034), but was not correlated with illness duration (r= -0. 333, P=0. 207) and BMI (t=- 0. 410, P= 0. 115). Conclusions The level of serum UA is lower in elderly patients with PD than in normal controls. There is correlation between the serum UA level and cognitive impairment. Lower serum UA level predicts worse cognitive scores.

objective To investigate preoperative donor and recipient assessment,choice of surgical options in living donor liver transplantation(LDLT).Methods The clinical data of 95 patients who underwent LDLT from January 1995 to October 2007 in our center were retrospectively analyzed.Of all,92 recipients were benign end-stage liver disease patients (including 45 patients with Wilson disease),and 3 were malignant hepatic carcinbma patients.Results Thirty-one fight lobes without middle hepatic vein(MHV),3 right lobes with MHV,51 left lobes with MHV.and 10 left lobes or left lateral lobes without MHV were obtained.All the donors recovered after operation. Recipients with benign end-stage liver disease were followed up for 1 to 86 months,and the 1-,3-,5-year accumulative survival rates were 89%(82 cases),78%(71 cases)and 73%(67 cases),respectively. The 1-,3-,5-year survival rates of patients with Wilson disease were 92%(42 cases),89%(40 cases)and 76%(34 cases),respectively. For the 3 patients with malignant hepatic carcinoma,2 died and 1 was alive and well. The copper metabolism was back to normal in both donors and recipients. Conclusions Establishment of a system for the safety of donors is basic for LDLT. The key to raise the recipients' survival rates is to choose the optimal surgical approach. LDLT is effective in treating Wilson disease.
