Objective To study interleukin-1 receptor(IL-1R) and connexin(Cx36) gene expression following Mg 2+-free-induced seizures in cultured developing neuron. Methods Rat embryo cortical neurons cultured for 6 and 17 days were exposed to Mg 2+-free media to induce seizure. At different time after Mg 2+-free treatment, real-time RT-PCR was used to detect IL-1R and Cx36 mRNA expression. Results 1. IL-1R mRNA expression transiently decreased after Mg 2+-free treatment in neurons cultured for 6 and 17 days in vitro. Then the levels of IL-1R mRNA expression recovered in neurons cultured for 6 days, but IL-1R mRNA expression were increased in neurons cultured for 17 days compared with control group and the peak was at 24 hours. 2. In neurons cultured for 6 days in vitro, Cx36 mRNA expression increased after Mg 2+-free treatment compared with control group, the peak was at 24 hours. But in neurons cultured for 17 days in vitro, Cx36 mRNA expression decreased at 6 hours after Mg 2+-free treatment compared with control group, the peak was at 24 hours. Conclusions IL-1R mRNA and Cx36 mRNA expression following Mg 2+-free-induced seizures are different between the neurons cultured for 6 and 17 days in vitro. This is possibly related to the different neuron injury between 6 and 17 days in vitro following seizures.

Objective:To investigate whether radiotherapy should be delivered before the application of immune checkpoint inhibitor PD-1 in patients with advanced non-small cell lung cancer (NSCLC) and evaluate the effect of previous radiotherapy on the efficacy and pulmonary toxicity of PD-1 inhibitor.Methods:Clinical data of patients with stage Ⅳ NSCLC who received immunotherapy in Henan Cancer Hospital from March 2015 to September 2019 were retrospectively analyzed. The baseline data of patients, the status of radiotherapy and immunotherapy and the pulmonary toxicity were collected. According to whether radiotherapy was given before PD-1 inhibitor application, all patients were divided into the previous radiotherapy and non-radiotherapy groups. Survival analysis was performed by Kaplan- Meier method. Results:A total of 90 patients were enrolled including 39 cases in the previous radiotherapy group and 51 cases in the non-radiotherapy group. The median follow-up time was 22.9 months. The median progression-free survival (mPFS) in the previous radiotherapy group was 7.5 months (95% CI 5.4-9.5 months), significantly longer compared with 4.1 months (95% CI 3.1-5.1 months) in the non-radiotherapy group ( P=0.003). The median overall survival (mOS) significantly differed between two groups[15.2 months (95% CI 12.3-18.1 months) vs. 9.3 months (95% CI 6.1-12.5 months)]( P=0.040). The incidence of pulmonary toxicity showed no significant difference between two groups ( P=0.154). Conclusions:Patients with stage Ⅳ NSCLC patients in the previous radiotherapy group obtain significantly better mPFS and mOS and similar pulmonary toxicity compared with their counterparts in the non-radiotherapy group. Nevertheless, the findings remain to be validated by subsequent investigations with larger sample size.

Background Studies demonstrated that human amniotic epithelial cells (AECs) have some characteristics of embryonic stem cells and they were used to re-establish the surface of eyes. Human AECs may serve as new seed cells in tissue engineering for corneal epithelium reconstitution in the future. Objective The present study was to investigate the application value of human amniotic epithelium cells transfected by lentiviral vectormediated enhanced green fluorescent protein (EGFP) gene as new seed cell source for engineering the corneal surfacelayer. Methods Lentiviral vector carrying the objective gene EGFP was transfected into human amniotic epithelial cells (pLenti6/V5-DEST),and the transient expression of the transgene in the human amniotic epithelial cells was observed under the fluorescence microscope. Flow cytometry was used to detect the positive expression rates of EGFP in transfected cells. The transfected human amniotic epithelial cells were seeded onto the fresh corneal stromal surface of New Zealand white rabbit and cultured in vitro. The stem cell deficiency ( SCD ) models were established by cutting off the limbus of cornea in 20 eyes of New Zealand white rabbits, and the model rabbits were then divided into 2 groups randomly. The transplanted grafts carrying the pLenti6/V5-DEST-EGFP gene-transferred human amniotic epithelium cells were regarded as the pLenti6/V5-DEST-EGFP group, and the corneal stroma graft without any epithelial cell served as the control group. The opacity of stroma and corneal conjunctivalization and vascularization were observed daily. The rabbits' eyes were extracted one month after operation. The expression of EGFP in the cornea was detected under the fluorescence microscope, and the expression of CK8, CK18 and CK12 in cornea was detected by immunohistochemical staining. Results The shape of the transferred human amniotic epithelial cells resembled normal human amniotic epithelial cells. 48 hours after the transient transfection of EGFP presented with the highest expression level throughout the observation duration, with a positive expression rate of EGFP of 61.5% ,showing significant differences in comparison with that of 12 ( 5.24% ) , 24 ( 38.27% ) or 96 ( 39. 10% ) hours ( P <0. 05) post-transfection; but no obvious difference was found in the positive rate of transiently transfected EGFP between 48 hours and 72 hours ( 58.36% ) ( P>0. 05 ). Six cornea grafts were clear in 1 month and two corneas were rejected during the observation period in the pLenti6/V5-DEST-EGFP group. A few new blood vessels were seen around the graft. Ten corneas of the control group became opaque and cloudy with new blood vessels growth around the grafts. Imunohistochemistry revealed the positive expressions of CK8, CK1 8 and CK12 in the corneal epithelial layer in the pLenti6/V5-DEST-EGFP group. However,the expression of CK12 was absent in the control group. Conclusion Human amniotic epithelium cells transfected with the pLenti6/V5-DEST-EGFP gene is a new and ideal feed cell type to reconstruct the corneal surface layer. Lentivirus is a relatively safe gene transfection vector.

OBJECTIVERett syndrome (RTT) is a neurodevelopmental disorder which causes severe mental retardation. This study aimed at elucidating clinical features of 66 Chinese RTT cases diagnosed by The Department of Pediatric Neurology, Peking University First Hospital since 1987, and at analysis of the MeCP2 genotype / phenotype correlation.
METHODSSixty-six RTT cases were followed up every one to two years to get the information of their clinical manifestations and the response to the L-carnitine treatment which was administered to the patients at a dose of 80-100 mg/(kg d). MeCP2 mutation analysis by PCR and sequencing were performed on 39 cases.
RESULTSIn this cohort of cases, the onset of the disease occurred between 3 and 38 months of age, 89% of the cases lost their purposeful hand use at 7 months to six years of age, all the cases had stereotype hand movement which presented at 1 to 5 years of age, 85% of the cases lost language ability at 11 months to eight years of age, 21% of the cases lost the ability of walking at ages of 2 years and 9 months to 15 years. The symptoms/signs such as small head circumference, seizures, breathing irregularities, teeth grinding, scoliosis/ kyphosis were presented in many of the cases. The clinical manifestations were improved in 6 cases after L-carnitine treatment. MeCP2 gene mutation was found in 64% of the cases. Two cases with non-sense mutation C502t (amino acid change R168X) died, two cases with missense mutation C397T (amino acid change R133C) and one case with missense mutation A398T (amino acid change R133H) preserved several words.
CONCLUSIONDeceleration of the head growth, loss of acquired purposeful hand use, stereotype hand movement and language deterioration were the main characteristics of RTT. L-carnitine could improve the clinical manifestation of some cases. There are some correlations between MeCP2 genotype and phenotype.
