The treatment of hereditary retinal disease is still one of the contemporary scientific problems.Leber congenital amaurosis (LCA) is one type of congenital retinal diseases.Desirable results have been achieved in ongoing clinical trials of gene therapy for LCA,and the efficacy and safety in the intraocular injection of a gene inserted in an adeno-associated virus (AAV) have been verified abroad.These results bring hope and opportunity to LCA patients.China has more hereditary retinal disease patients,but gene therapy for hereditary retinal disease and LCA is lacking.Rightly interpreting and objectively evaluating the clinical trials of gene therapy of LCA will provide us with many important references and useful clues to further help us organize and implement clinical trials of gene therapy for hereditary retinal disease in the future.

Objective To investigate the clinical value of King's College Hospital Criterion (KCH),Canadian Waitlisting Algorithm Criterion (CanWAIT) and Japanese Liver Transplantation Criterion (JLT) in predicting the prognosis of the patients with chronic severe hepatitis in China. Methods Fifty-five patients with chronic severe hepatitis were classified respectively by the three liver transplantation criteria.Those who were in line with the criterion were ascribed the matched criteria group (MCG),while those who were not in line with the criterion were ascribed the unmatched crite ria group (UCG).The end point of observation was the 90th day after their admission.The survival time and the mortality were compared between the MCG and UCG.The predictive ability for each cri- terion and their correlation with the clinical stages of chronic severe hepatitis were analyzed.Results Seventeen cases accorded with KCH and CanWAIT,while 38 cases did not accord with KCH and CanWAIT.The median survival time (MST) and their mortality in MCG group were 17.5 days and 100.0% respectively,while those in UCG group were 69.2 days and 34.2% respectively.Twenty- one cases accorded with JLT,while 34 cases did not accord with JLT.The MST and their mortality in MCG were 17.7 days and 95.2% respectively,while those in UCG group were 75.2 days and 29.4% repsectively.There were significant differences in MST and mortality between MCG group and UCG group with the 3 criteria (P

Objective To investigate the effect of palato-pharyngo-plastry on patients with coronary heart disease (CHD) plus obstructive sleep apnea hypopnea syndrome (OSAHS). Methods The 113 OSAHS patients with CHD after palato-pharyngo-plastry from January 2001 to December 2006 were enrolled and followed up. The other 125 cases treated with continuous positive airway pressure (CPAP) were as control group. Results The fundmental factors of CHD including cholesterol, triglyeride, fasting blood glucose and body mass index (BM1) showed no statistical differences between two groups (x2 or t= 4.788, 0.479, 0.541, all P>0.05) . Only the oxyhemoglobin saturation during sleep was higher in study group than in control group [(91.2± 2.5)% vs. (87.6±4.2)%, P=0.046]. The angiography showed that 87 cases (77.0%) retained stable, 24 cases (21.2%) became severe in study group. As compared with control group, there were no statistical differences (both P>0.05). 37 cases (32.7%) in study group and 58 cases (46.4%) in control group who suffered from angina became severe with statistical differences between two groups (x2=4.615, P=0.032). The incidences of myocardial infarction and sudden death were lower in study group (3.5% and 0.8%) and in control group (5.6% and 2.4%), showed no statistical, difterences be tween twogroups. x2=0.571 and 0.495, P>0. 05). Conclusions Compared with CPAP, the palato-pharyngo-plastry can improve oxyhemoglobin saturation and reduce angina symptom, but has no better effect on progress of coronary atherosclerosis and acute coronary disease than CPAP.

Objective Intranuclear forkhead/winged helix transcription factor p3(Foxp3) plays a key role in T cell-mediated immunosuppression.The present study was performed to investigate the effects of high mobility group box-1 protein(HMGB1) on Foxp3 gene as well as protein expressions in splenic regulatory T cells(Tregs) and their potential regulating mechanisms in mice.Methods CD4+CD25+Tregs isolated from the spleens of male BABL/c mice by magnetic beads were seeded on 96-well(1?105 cells/well) cell culture plates coated with anti-CD3(1 ?g/ml) and soluble anti-CD28(1 ?g/ml),and the cells were stimulated with HMGB1 at various intervals or at different concentrations.After being stimulated,the Foxp3 mRNA/protein expressions in the Tregs were determined.The time-dependent and dose-dependent responses between HMGB1 and intranuclear Foxp3 expression were analyzed by flow cytometry,and the expressions of Foxp3 mRNA of Tregs were analyzed by quantitative PCR of SYBR GREEN.Results After stimulation with HMGB1,the intranuclear Foxp3 protein and mRNA expressions of splenic Tregs in mice were markedly down-regulated in 24 h to 72 h(P

AIM: To observe the expression of apoptosis-related proteins in hippocampal neurons of (ovariectomized) (OVX) rats and explore the neuroprotective mechanism of the App17-mer peptide. METHODS: Female Wistar rats were randomly divided into three groups. Bilaterally ovariectomized rats with injection of App 17P peptide (3.5 ?g in 0.1 mL/per rat, three times a week) formed the experimental group (17P+ OVX group). Anti-AIF, Bcl-2 and Bax antibodies were applied in the immunohistochemistry experiment. TUNEL was employed to detect apoptosis. RESULTS: The number of apoptotic neurons was clearly higher in hippocampal and cortex in OVX group than that in OVX+17P group. Immunohistochemistry demonstrated the increased expression of AIF, Bax in hippocampal neurons of OVX group. OVX group showed a significantly reduced expression of Bcl-2 in hippocampal neurons. Hippocampal tissue from OVX group showed the increased expression of AIF, Bax, and showed diminished expression of Bcl-2, treating with App17-mer peptide normalized the expression of these proteins. CONCLUSIONS: The expression of apoptosis-related proteins were abnormal in the OVX rats, App17-mer peptide normalized these changes. Estrogen deficiency induced neuronal apoptosis, and App17-mer peptide diminished apoptosis.
