Objective To evaluate the role of mitochondrial fission in anoxia-reoxygenation injury to rat hippocampal neurons.Methods Neurons were enzymatically isolated from hippocampi of newborn Sprague-Dawley rats (less than 24 h old).The primary hippocampal neurons were cultured and seeded in 25 mm × 25 mm culture flasks at a density of 7 × 105/ml.The cultured neurons were randomly assigned into 3 groups (n =18 each) using a random number table:control group (C group),anoxia-reoxygenation group (I/R group),and mitochondrial fission inhibitor mdivi-1 group (M group).In group I/R,the vehicle dimethyl sulfoxide (DMSO,final concentration ＜ 0.1％) was added prior to anoxia and the cells were then incubated for 40 min.In group M,mdivi-1 (dissolved in DMSO,final concentration of DMSO ＜ 0.1％) was added prior to anoxia and the cells were then incubated for 40 min.The hippocampal neurons were subjected to oxygen-glucose deprivation (OGD) for 6 h followed by restoration of O2 supply for 20 h.After 20 h of reoxygenation,the level of reactive oxygen species (ROS) (by ELISA),cell apoptosis (using flow cytometry),and expression of mitochondrial fission protein Drp1,Bcl-2 and Bax (by Western blot) were measured.The apoptosis rate and the ratio of Bcl-2 to Bax were calculated.Results Compared with C group,ROS content and apoptosis rate were significantly increased,the expression of Drp1 and Bax was up-regulated,the expression of Bcl-2 was down-regulated,and the ratio of Bcl-2 to Bax was decreased in I/R group (P ＜ 0.05).Compared with I/R group,ROS content and apoptosis rate were significantly decreased,the expression of Drp1 and Bax was down-regulated,the expression of Bcl-2 was up-regulated,and the ratio of Bcl-2 to Bax was increased in M group (P ＜ 0.05).Conclusion Mitochondrial fission is involved in anoxia-reoxygenation injury to rat hippocampal neurons via mitochondria-mediated apoptotic pathway.

Aim: To prepare a novel contraceptive patch containing gestodene(GEST) and ethinylestradiol(EE), and to study the in vitro characterization and in vivo contraceptive effect. Methods: Double-layer technique was applied to sustain steady 7-day permeation flux of drugs. Polariscope examination was carried out to observe the drug distribution behavior in the patch. Uniformity, adhesion, skin irritation, release and permeation tests were conducted to evaluate in vitro characterization. Anti-implantation and anti-fertility experiments were carried out to investigate its contraceptive effect. Results: The in vitro release profiles of both drugs were in accordance with Higuchi equation. The daily permeated amount of GEST per 10 cm2 patch was about 75 μg while the amount of EE was 30 μg.The in vitro transdermal permeation of both drugs from the patches displayed a zero-order process. Permeation rate constants were 0. 377 μg/(cm2·h) for GEST, and 0. 092 μg/(cm2· h) for EE, respec-tively. After transdermal administration, the embryonic number of the test groups was zero, and the uterus coefficients of those groups were significantly reduced compared with those of the control group (P < 0. 01). Conclusion: Double-layer transdermal drug delivery system(TDDS) could allow the steady 7-day permeation flux of drugs when the drug ratio between the immediate-release layer and the reservoir layer was 1:4. In vivo charac-terization demonstrated its contraceptive effects. The prepared novel patch might be a promising non-oral contra-ceptive preparation.

Objective To investigate positive picobirnaviruses(PVBs)infection and its association with unex-plained diarrhea in children. Methods From January to December 2015,the Clinical Microbiology Testing Center of Xuzhou Central Hospital as the sampling location,7 PVB reverse transcription - polymerase chain reaction(RT - PCR)- positive fecal samples with diarrhea were collected from children under 6 years old and 4 samples from healthy chil-dren were obtained and all the samples were analyzed by viral metagenomics to investigate the relationship between PVBs and diarrhea in children. Phylogenetic analysis of RdRp in the isolated PVB sequences was carried out to clarify the relationship between PVB classification and diarrhea. Results All the 7 diarrhea feces contained high titers of PVB sequences,while 3 of the controls were negative,and 1 with low titers of PVB. RdRp analysis was carried out on the iso-lated PVB sequences,which displayed that 7 RdRp sequences caming from 7 fecal samples separately,so named ChXz- 1 to ChXz - 7 respectively. Phylogenetic analysis based on the predicted amino acid sequences of RdRp from this study and whole RdRp sequences available in the GenBank database indicated that the 7 RdRp sequences belonged to 3 genogroups,in which ChXz - 1,ChXz - 2,ChXz - 3 belonging to genogroup Ⅰ,ChXz - 4,ChXz - 5,ChXz - 7 belong-ing to genogroup Ⅱ,and ChXz - 6 belonging to genogroup Ⅲ. Conclusions PVBs might be the cause of diarrhea in children in this study,and all the 3 different PVBs may lead to diarrhea.
