Objective To investigate the surgery opportunity choice of congenital esotropia.Methods A retrospective research was taken using the clinical data and the results of the treatment of 146 inpatients with congenital esotropia in our department from Mar 2012 to Mar 2015.The correction rate,lackingcorrection rate,and over-correction rate were compared between early surgery group and late surgery group on time of 1 week after surgery and 6 months after surgery,respectively.Results In all the 146 patients,88 (60.3％) had an esotropia deviation greater than or equal to 40 pupil distance (PD),38 (26.0％) combined with amblyopia,12 (8.2％) combined with nystagmus,30 (20.5％) combined with inferior oblique muscle overaction,6 (4.1％) combined with dissociated vertical divergence (DVD).There was no significant difference between early surgery group and late surgery group on correction rate,lacking-correction rate,and over-correction rate on the time of 1 week after surgery and 6 months after surgery,respectively.Conclusions Congenital strabismus should take surgery at the early-stage,especially for those have large angles.It is better to be operated before 2-year old for a better formation and recovery of binocular visual function.

Objective To investigate the expression of microRNA-134 ( miR-134 ) , CREB and pCREB in the temporal lobe tissue of patients and epileptic rats and to explore their roles in pathogenesis of epilepsy.Methods Tempo-ral lobe tissue samples of 14 patients with refractory epilepsy and 10 non-epileptic patients, and hippocampus and brain tis-sue samples of 42 rats were used in this study.Forty-two healthy adult male Sprague-Dawley rats were randomly divided in-to 6 epilepsy groups (24 h, 72 h, 7 d, 14 d, 30 d, and 60 d after kindling epilepsy) and a normal control group (n=6 for all groups) .The rat model of epilepsy was generated by intraperitoneal injection of 127 mg/kg lithium chloride and 16-20 h later, 35 mg/kg pilocarpine.In the temporal lobe tissue of patients and hippocampal tissue of rats, the expression level of miR-134 was detected by real-time polymerase chain reaction.The expression levels of CREB and pCREB were de-termined by Western blot, and CREB and pCREB localization was assessed by immunohistochemistry.Results Compared with the control rats, the expression of miR-134 was significantly decreased in the temporal lobe tissue of experimental rats at 72 h,7 d,14 d, 60 d after kindling (P＜0.05),and no significant change at 24 h and 30 d after kindling (P>0.05). Expression of miR-134 in patients with refractory epilepsy was significantly lower than that of the controls ( P＜0.05 ) , while up-regulation of CREB expression was at the same time points (P＜0.05).Up-regulation of pCREB expression was at all the time points after kindling (P＜0.05).CREB and p-CREB expressions were seen in the nuclei of neurons, and significantly higher in patients with refractory epilepsy and epileptic rats.Conclusions The expression of miR-134 is sig-nificantly decreased and that of CREB and pCREB was significantly increased in the temporal lobe tissue of patients with re-fractory epilepsy and the hippocampal tissue of epileptic rats.These findings indicate that the signaling pathway of miR-134/CREB/pCREB may play an important role in the pathogenesis of epilepsy.

Objective The article was to speed up the dissolution rate of poorly soluble drugs, reduce the configuration time and improve the allocative efficiency by analysis on factors influencing dissolution and adoption of proper allocative approaches accord-ing to different characteristics of insaluble drugs. Methods 5 insaluable drugs were chosen for the study, which were ornithine as-partate, mezlocillin sodium and sulbactam sodium, teicoplanin, omeprazole sodium injection and imipenem and cilastatin sodium.The control group were allocated by routine configuration approach, while the experiment group were improved by increasing the amount of solvent, loosing the powder inside the bottle before configuration, reducing the bubble, adopting special solvent and increasing the dis-solution temperature.Observation and comparative experiment were made on two groups along with the timing from configuration to com-plete dissolution into clear transparent liquid. Results As to the average complete dissolution time of 5 drugs, significant difference was found between two groups([42±5]s vs [246±35]s, [3±1]min vs [30±3]min, [5±1]min vs [10±3]min, [5±3]min vs [10± 5]min, [2±1]min vs [10±1]min, P<0.05).Compared with the control group, the dissolution time of 5 drugs was cut down by 83%, 90%, 50%, 50%, 80%in experiment group. Conclusion Appropriate increase of solvent, loose powder, bubble reduction, special solvent and increased solution temperature contribute to shortening the dissolution time of insoluble drugs and improving the configura-tion efficiency of pharmacy intravenous admixture.

objective To determine the existence of virulence-associated invA gene in different genospeeies of Leptospira interrogans reference strains in China.and to understand the alterations of invA gene transcription and expression of L.interrogans strain Lai before or after infecting cells.Methods PCR was applied to detect the invA gene of four L.interrogans strains belonging to four different genospecies and L.biflexa strain Patoc Ⅰ.The entire invA genes from the L.interrogans strains were cloned and then sequenced.The prokaryotic expression system of invA gene of L.interrogans serogroup Icterohaemorrhagiae serovar Lai strain Lai was constructed.Using Ni-NTA affinity chromatography,the target recombinant protein rInvA was extracted and purified.Rabbits were immunized with rInvA to obtain antiserum and the titer of antiserum was determined by immunodiffusion test.A model of L interrogans strain Lai infecting human embryo kidney cell line HEK293 was established to detect the alterations of invA gene transcription and expression of the leptospiral strain before or after infecting the host cells by real-time fluorescent quantitative RTPCR and western blot assay.Results All the four tested L.interrogans strains had invA gene whereas L.biflexa strain Patoc Ⅰ not.The similarity of nucleotide and putative amino acid sequences of invA genes from the four L.interrogans strains belonging four different genospecies were 99.33%-100%and 98.66%-100%,respectively.The constructed prokaryotic expression system could efficiently express rInvA and the immunodiffusion titer of rabbit anti-rInvA serum was 1:16.After L.interrogans strain Lai infecting HEK293 cells for 30 min or above,the microbe could adhere the surface of the cells.On the 30 min after the infection,the mRNA level of invA gene of L.interrogans strain Lai was remarkably upregulated,and on the 45 min after infection the mRNA level presented a peak value and then graduated decreased.On the 45 min or 60 min after L.interrogans strain Lai infecting HEK293 cells,InvA protein could be detectable but before infection or after infection for over 90 min the InvA protein expression was negative.Conclusion The invA gene is a unique gene for pathogenic L.interrogans.The invA gene of L interrogans has characteristics of cell-touched expression and transient expression,which may have a close correlation with adhering and invading host cells.
