Objective To study the relationship between receptor interacting protein (RIP)1 and hepatocyte necropto?sis in isoniazid (INH) induced mouse model. Methods Kunming male mice were randomly divided into three groups. Con?trol group (C) received 0.3 mL of normal saline one time per day. INH group (INH) was injected intraperitoneally INH 100 mg/kg body weight, one time per day. Nec-1+INH group was injected intraperitoneally Nec-1 in 0.1%DMSO and 1 mg/kg body weight one time/12 hours, and INH was injected intraperitoneally at the same dose with that of INH group. All animals were treated for 7 days. Pathological changes of liver tissues were studied by HE staining. RIP1 expression was detected by immunohistochemical, Western blot and real-time PCR analysis. Levels of malondialdehyde (MDA), reactive oxygen species (ROS), glutathione (GSH) and superoxide dismutase (SOD) in liver homogenate were determined by colorimetric method. Re?sults Hepatocytes were arranged orderly in C group. The degeneration and necrosis of hepatocytes were found in Nec-1+INH group, and severe degeneration and necrosis of hepatocytes were found in INH group. Compared with C group, the ex?pression levels of RIP1, ROS and MDA were increased significantly, and the expression levels of GSH and SOD were de?creased significantly in INH group (P<0.05). INH-induced acute liver necroptosis was significantly alleviated after treat?ment with Nec-1. Compared with INH group, the expression levels of RIP1, MDA and ROS were significantly decreased, and the expression levels of GSH and SOD were significantly increased in Nec-1+INH group (P<0.05). Conclusion These re?sults suggest that RIP1 is involved in INH-induced hepatocyte necroptosis in mice. The inhibition of RIP1 expression might be a treatment strategy for prohibition of INH-induced acute liver necroptosis.

OBJECTIVE:To optimize the formulation of Dimemorfan phosphate tablets. METHODS:Using 60 min dissolution rate of dimemorfan phosphate as index,L9(34) orthogonal test was used to optimize the amount of starch,microcrystalline cellu-lose,croscarmellose sodium and concentration of HPMC E5 solution. The friability,hardness,60 min dissolution rate and main component were detected. The similarity of dissolution curves of Dimemorfan phosphate tablets was compared with that of imported tablets in 0.1 mol/L hydrochloric acid,pH 6.8 phosphate buffer,water and pH 4.0 acetate buffer. RESULTS:The optimized formu-lation of Dimemorfan phosphate tablet(1 000 tablets)was composed of dimemorfan phosphate 10 g,starch 60 g,microcrystalline cellulose 40 g,10% HPMC E5 solution and croscarmellose sodium 25 g. The friability,hardness,60 min dissolution rate and main component of 3 batches of Dimemorfan phosphate tablets prepared by optimized prescription were 0.42%-0.58%,9.8-10.5 kg,94.89%-96.21% and 99.21%-99.52%,respectively. In 4 dissolution mediums,similar factors f2 of dissolution curves between prepared tablets and imported tablets were above 50. CONCLUSIONS:Dimemorfan phosphate tablets were prepared successfully. The optimized formulation is rational. The dissolution behavior of prepared tablets is similar to that of imported tablets in vitro.

Objective To analyze the results of the final aviation medical examination of 1281 students recruited into Air Force youth aviation schools in Hunan and Hubei provinces in order to provide reference for establishing the items and standards of medical selection .Methods The data of 1281 students who participated in final aviation medical examination of Air Force youth aviation schools in 2016 were collected , who came from 28 cities in the above two provinces .The disqualification rate and related unqualified medical items were calculated , and the differences of the disqualification rate and medical geographical areas in the 28 cities were analyzed .Results According to the disqualification rate , the top five departments were ophthalmology , otolaryngology, surgery, radiology and ultrasonic departments .The top 10 unqualified items were the lack of distant vision , fundus diseases , nasal anomaly , ametropia and strabismus , spine abnormality , audition abnormality, vestibular function badness , vitreous opacity, and lens abnormalities.There was no significant difference between the 28 cities in the disqualification rate (P >0.05) or between the two provinces (P >0.05). Conclusion The results of the final aviation medical examination reflect the quality and efficiency of the initial aviation medical examination .To improve the quality of medical selection , further research is needed to set a scientific standard for the initial aviation medical examination while strengthening the scientific protection and intervention of distant vision .The efficiency of selection depends on improving the accuracy of initial aviation medical examination in nasal cavity structure, body shape ,and lens opacity .With a better understanding of the disqualification rate and abnormal items in different cities , a scientific arrangement of professional staff and technical force can make the initial aviation medical examination better, thus effectively reducing the rate of false elimination rate and misdiagnosis .

Objective To explore the effect of different cold ischemia (CI)times on the patterns of intra-graft T cell activation gene-3 (TCA-3) expression early after isogeneic half liver transplantation (PLT)in mice. Methods The models of C57BL/6 full-size(FS) and PLT were established.The CI time was 1,4 and 8 h.Specimen were collected at 4 and 24 h post-reperfusion.Ribonuclease protection assays (RPA)was used to evaluate serial mRNA expression of the TCA-3 chemokine in all mice.Histopathology was used to examine cold ischemia injury in the liver grafts. Results A total of 45 control and 30 PLTs were performed.The survival rate at 7 day after control and PLT was 100％.Quantitative analysis demonstrated the levels of TCA-3 mRNA expression were low at 4 h after reperfusion in control group with 1,4,8 h CI.The levels of TCA-3 significandy increased at 4 h after reperfusion in PLT group with CI of 1,4,8 h and the difference between the two groups was statistically significant ( F =7.41,P ＜ 0.05 ). TCA-3 mRNA expression significantly decreased at 24 h after reperfusion in two groups. But the difference was not statistically significant ( P ＞ 0.05 ). Histopathology showed severer cold ischemia injury in PLT grafts compared with control grafts. Conclusions The expression of TCA-3 significandy increased early after PLT and played an important role in cold ischemia injury.TCA-3 could be used as the early therapeutic target for reducing ischemia injury in PLT grafts.

Objective At present, there is no study on effect of levetiracetam(LEV) on the gray matter structure remodeling in benign epilepsy children with central temporal spikes(BECTS).The purpose of this study was to study the influence of LEV on the gray matter structure in BECTS and to evaluate the mechanism of LEV on the brain structure of BECTS through using voxel-based MRI morphological(VBM) methods.Methods From January 2014 to September 2016, twenty-four BECTS treated with LEV(LEV group), twenty-four drug-na?ve BECTS(untreated group) and twenty-four normal children(normal group) consulted in department of Neurology, Nanjing Children′s Hospital and the Nanjing Military Region, Nanjing General Hospital were continuously included to receive three-dimensional T1-weighted imaging with 3T MRI and the gray matter volume was calculated by VBM.We compared the difference of grey matter volumes of the three groups and analyzed their correlation with epilepsy duration, age of onset and medication time and other clinical index.Results Compared with the normal group, the grey matter volume of bilateral thalamus were decreased, and the volume of bilateral Rolandic areas, anterior insula/frontal operculum/frontal triangle, left supplementary motor area, paracentral lobule, precentral gyrus, superior frontal gyrus and right middle frontal gyrus were increased in the untreated group, but the grey matter volume of the bilateral Rolandic areas, frontal operculum and left supplementary motor area were decreased in the LEV group.Compared with the untreated group, the grey matter volume of bilateral supplementary motor, left paracentral lobule, precentral gyrus, bilateral anterior insula/frontal operculum/frontal triangle, left superior frontal gyrus and right middle frontal gyrus in the LEV group were decreased.The grey matter volume of left anterior insula/frontal operculum areas was negatively correlated with the medication time in LEV group(r=-0.527, P<0.01).Conclusion T The mainly representations of BECTS are thalamic gray matter damage and epileptic-related cortical area irritation structural abnormalities, but the LEV could reshape the epilepsy-related cortical area and the gray matter in the brain area associated with clinical symptoms.
