Based on the standard strain-Vibrio parahaemolyticus BJ1.1997, temperature (7?C～43?C) and salinity (0.5%～9.5% NaCl) which affected its growth status was studied with uniform design. The results showed that Logistic equation was optimal in primary models, the second was Gompertz equation, the last was Linear equation, so growth parameters can calculated from Logistic equation. The secondary model was developed by square root models, its r value was 0.9863, the lowest growth temperature was 9.0506?C and the highest growth salinity was 5.93% [the corresponding lowest growth water activity (Aw min) was 0.9227]. Through F test, residual analysis and evaluation by bias factor and accuracy factor, the model can exactly describe the relationship between the growth rate and combined effect of temperature and salinity (water activity).

Objective To observe the effect of repetitive transcranial magnetic stimunation (rTMS) on neuropathic pain after spinal cord injury. Methods From June, 2014 to December, 2015, eight spinal cord injury patiens with neuropathic pain were treated with rTMS for five weeks. They were assessed with Numerical Rating Scale of pain and Self-Rating Scale of Sleep before and after treatment. Results After treatment, the score of Numerical Rating Scale decreased 4 to 6 points, namely from severe pain to mild to moderate pain. The score of Self-Rating Scale of Sleep decreased 9 to 20 points. Conclusion rTMS may relieve neuropathic pain after spinal cord injury, and can be combined with medcine.

Background The treatment timing and method of amblyopia rely on the plasticity of visual system.Synapsin is a family of presynaptic terminal specific protein.Its role in visual developmental plasticity is below understood.Objective To investigate the dynamic expressions of synapsin (T-synapsin),and phosphorylation of synapsin (p-synapsin Ⅰ a/b) in visual cortex of normal mice and further explore the role of synapsin in plasticity of visual system.Methods Forty-two clean neonatal C57BL/6 mice were collected.The mice were sacrificed at postnatal 7,14,21,28,35,42,60 days respectively to obtain the tissue samples of visual cortex.Expression levels of T-synapsin and p-synapsin in the visual cortex following the ageing were quantitatively detected using Western blot assay.Results The expression of synapsin in normal mice showed a dynamic increase with the ageing.The T-synapsin Ⅰ a/b/β-actin value in visual cortex was (21.32 ± 3.27) ％,(56.27 ± 10.18) ％,(77.05 ± 10.05) ％,(83.75±10.52) ％,(94.69±11.46)％,(98.75±5.86) ％ of adults mice (postnatal 60 days,P60) in the mice of postnatal 7,14,21,28,35,42 days,respectively,showing a significant difference among them (F =69.538,P ＜ 0.001).Compared with the adult mice,the T-synapsin Ⅰ a/b/β-actin value in the mice of P7,P14,P21,P28 was significantly lower (all at P＜0.05),but no significant difference was found between P35 and P60,P42 and P60 (P =0.280,0.798).The development trend of different synapsin subtypes,such as T-synapsin Ⅰ a/b,T-synapsin Ⅱ a,T-synapsin Ⅱ b and T-synapsin Ⅲ a,was not quite the same during the ageing.The expression of T-synapsin Ⅱ a and Ⅲ a increasing more slowly with development,and kept increasing until P60.Significant differences were found among various age of mice in T-synapsin Ⅱ a,Ⅱ b,Ⅲa respectively(F =42.492 55.595,39.172,all at P＜0.001).The p-synapsin Ⅰ a/b level in the visual cortex elevated with the ageing of the mice,and that peaked in P21 mice,which was (2.86±0.17) times more than that in adult mice.After that,the expression level of p-synapsin Ⅰ a/b dropped rapidly.A significant difference was found in the p-synapsin Ⅰ a/b expression among different ages of mice (F =22.620,P ＜ 0.001).Conclusions Synapsin level in visual cortex presents a developmental change which correlated with the onset and decline of the critical period.Synapsin is probably involved in the regulation of neural plasticity in visual cortex in critical period.

Background Plasticity of visual system is one of the mechanisms of deprivation amblyopia.Our previous study showed that synapsin plays a role during visual developmental plasticity,and conventional protein kinase C-γ (cPKC-γ) probably is one of upstream kinases of synapsin.However,whether or how the cPKC-γ plays its effects on visual developmental plasticity is below understood.Objective This study was to investigate the dynamic expression of cPKC-γ in visual cortex of normal mice and explore the effects of abnormal visual experience on cPKC-γ expression.Methods The bilateral visual cortex tissues were obtained from 36 clean C57BL/6 mice at postnatal (P) 7,14,21,28,35,42 days respectively and 6 mice for each for the researching of cPKC-γ dynamical expression in visual cortex over aging.Other 24 C57BL/6 mice were randomized into developmental phase group and adult phase group,12 for each group.The monocular deprived (MD) models were established by suturing the upper and inferior eyelides in P14 mice for 14 days in 6 mice in the developmental phase group and 6 healthy mice served as controls,and MD models were established in the same way in 6 P60 mice in the adult phase group,and the same aged mice (6 mice) were used as controls.The mice were sacrificed and bilateral visual cortexes were obtained.The expression of cPKC-γ protein in the visual cortex was quantitatively detected using Western blot assay.The study protocol was approved by Ethic Committee of Tongren Eye Hospital.The use and care of the experimental mice followed the ARVO Statement.Results The cPKC-γ protein was faintly expressed in visual cortex in normal P7 mice,with the related expressing level of (39.74± 11.22)％ and (40.78± 10.37)％ in the left and right cortex,respectively.The expressing level of cPKC-γ protein was gradually increased over aging,with the peak value of (138.68±15.73)％ and (138.47±23.48)％ in P21 mice.A significant difference was found in the expression of cPKC-γ protein in various ages of mice (Fage =57.174,P =0.000),and the expression of cPKC-γ protein was not significantly different between the left and right visual cortexses (Flateral =0.059,P =0.809).No significant differences were found in the expression of cPKC-γ protein on bilateral visual cortexes among the mice of the developmental phase group and adult phase group (Fage =1.798,P =0.159) or among the MD group and normal control group (Fgroup =0.104,P=0.749).Conclusions The dynamic expression of cPKC-γ in the visual cortex of normal mice presents a consistant tend with the aging and development of visual critical period.MD does not affect the expression of cPKC-γ protein in bilateral visual cortexes.Further researches should be performed in the activity of cPKC-γ protein in MD mice.

Objective To explore the effect of comprehensive intervention on anxiety in patients of acute myocardial infarction (AMI) undergoing intra-aortic balloon pump (IABP). Methods 50 patients with AMI undergoing IABP with the score of Hamilton Anxiety Rating Scale (HAMA) more than 14 points, were divided into conventional intervention group (n=25) and comprehensive intervention group (n=25). The conventional intervention group received all the conventional nursing measures including cognitive behavioral intervention, and the comprehensive intervention group received propofol intravenous pumping in addition with Ramsay sedation at II-III level. The vital signs, HAMA scores, major cardiovascular events, and vascular complications were recorded before and the 1st-5th days after intervention. Results The HAMA scores, systolic blood pressure, diastolic blood pressure and mean pressure decreased in most of the time points after intervention in the comprehensive intervention group (P<0.05). And there was no complication such as low blood pressure, respiratory depression. The incidence rates of cardiac arrhythmias, puncture hematoma/bleeding and catheter displacement were lower in the comprehensive intervention group than in the conventional intervention group (P<0.05). Conclusion Comprehensive intervention can improve the symptoms of anxiety in the patients with AMI undergoing IABP, and reduce the incidence of arrhythmia, vascular complications and catheter displacement.

Objective:To investigate the differences in related indices of ulcerative colitis (UC) respectively induced by free drinking and intragastric administration of dextran sodium sulfate (DSS) in mice to provide experimental reference for the optimization of UC model.Methods:Totally 30 C57BL/6 mice were randomly divided into the normal control group,free drinking group and intragastric administration group with 10 ones in each.The mice drank water freely with free drinking or intragastric administration of 3% DSS solution at the dose of 4 g·kg-1·day-1 for 7 days to establish the UC model.The differences in disease activity index (DAI),histological damage sore and activity of myeloperoxidase (MPO) among the groups were compared.Results:Two mice died during the experiment in the free drinking group,and DAI of survival mice was (8.8±1.6).There was no death of mice in intragastric administration group,and DAI was (9.0±0.8),and there was no significant difference in DAI between the groups (P>0.05),while the coefficient of variation in the free drinking group was higher than that in the intragastric administration group (18.7 vs 8.6).The colonic histological damage score of the free drinking group and the intragastric administration group was 24.8±4.2 and 27.0±2.8,respectively,which was typical inflammatory change with no significant difference (P>0.05),while the coefficient of variation of the free drinking group was higher than that of the intragastric administration group (16.9 vs 10.4).MPO of the normal control group,free drinking group and intragastric administration group was (0.41±0.03),(2.32±0.34) and (2.05±0.18) U·g-1,respectively.Compared with the normal control group,significant difference in MPO was shown in the free drinking group and the intragastric administration group (P<0.01),while there was no significant difference in MPO between the groups (P>0.05),and the coefficient of variation in the free drinking group was higher than that in the intragastric administration group (14.7 vs 8.8).Conclusion:Both free drinking and intragastric administration of DSS can successfully induce the UC model in mice.Compared with the free drinking group,the intragastric administration group has low mortality rate and low coefficient of variation.Therefore,intragastric administration has more advantages than free drinking in inducing the UC model in mice.
