Herpes simplex keratitis (HSK),which is caused by infection of herpes simplex virus,is a kind of disease with high incidence and blinding rate.The mechanism of HSK is complex and always attracts the attention of researchers.It is considered as an immune response to viral infection and is related to several factors,such as pathway of infection and immunoregulation.This review reveals the latest advance of the mechanism of HSK in the aspects of viral infection and latency,apoptosis,immunity.

Objective To explore the impact of intrapartum mild asphyxia on motor development in infants. Methods 30 infants with any of the following were as asphyxia group: heart rate more than 160 beats/min in the process of childbirth, and then down to 70-80 beats/ min, no cyanose; Apgar score 1 min more than 8. Other 30 normal infants were as control group. They were assessed with Neuropsychological Development Scale for 0-6 Years Old 3, 6 and 9 months after birth. Results Opisthotonos was more frequent in the asphyxia group than in the control group (P<0.01) 3 months after birth, but there was no significant difference in total score (P>0.05). Sitting forward was more frequent in the asphyxia group 6 months after birth, and the score of motor was less in the asphyxia group than in the control group (P< 0.05). More of the asphyxia group couldn't stand with help, and with poor motor score 9 months after birth (P<0.05). Conclusion Intrapartum mild asphyxia may infulence the motor development of infant in long-term.

The Effects of hydrogen peroxide(H2o2) on the ultrastructure, cellular pea-meability barrier and 3H-TdR-DNA leakage of C. albicans were studied. Damage of the cell, especially leakage of cytoplasm were found under transmission electron microscope. Morphological changes and small hole like structures were also found under scanning electron microscope. Radioactivity assay of the leakage of 3H-TdR-DNA leakage of C. albicans further suggested that the 3H-TdR-DNA leakage of C. albicans was directly due to the damage of cellular permeability barrier. Negative correlation (r=+0.8392--0.9915)between the extent of 3H-TdR-DNA leakage and the number of surviving colony-forming units was found. This indicated that the damage of cellular permeability barrier and leakage of DNA of C. albicans caused by H2o2 was one of the most importent causes of cell killing.

Lysophosphatidic acid is a intermediary metabolite in lipid metabolism, mainly produced from activated platelets. It may cause the apoptosis of hippocampal neurons, abnormal phosphorylation of tau protein and increased permeability of the tight junction of endothelial cells, which is closely correlated with pathological changes of ischemic cerebrovascular diseases, Alzheimer's disease and vascular dementia. It is shown that lysophosphatidic acid may induce the opening of the blood-brain barrier under pathological conditions, and enters central nervous system through the blood-brain barrier, and causes different effects of pathological changes by acting on various cells.

Objective]To investigate the application value of four-dimensional ultrasound with high definition flow(HD flow) in the observation of fetal pulmonary vein.[Methods]From June 2015 to June 2016,130 fetuses in our hospital underwent prenatal fetal echocardiography were included in this study. Color Doppler and high definition flow imaging were used to observe and count the number of pulmonary veins in the fetal four chamber view. In the condition of opening HD flow ,the 3D volume data was collected from the heart of the fetal four chamber view,and the 3D images of the fetal pulmonary vein were obtained by using the post processing software. Comparisons were made between the three methods for visualization numbers of the normal fetal pulmonary veins. For 5 cases of abnormal pulmonary venous drainage,STIC combined with HD flow technique was used to carry out three-dimensional reconstruction of pulmonary veins,to observe the abnormal drainage.[Results]The display rate of HD flow on fetal pulmonary veins was higher than that of color Doppler. For the 17~32 weeks fetal,four-dimensional ultrasound combined with HD flow could better observe the spatial location of pulmonary veins.[Conclusions]STIC combined with HD flow technology can display fetal pulmonary veins better in the second and early-third trimester of pregnancy ,and three-dimensional reconstruction of the image is more intuitive ,helpful to understand the spatial relationship.

Objective To optimize the formulation of sinomenine hydrochloride pulsatile drug delivery tablets by central composite design-response surface method.Methods The tablets containing sinomenine hydrochloride were prepared by dry-compression coating technique.The influence factors included the amount of sodium carboxymethyl starch in core tablets, the ratio of HPMC/carrrageenan,and the amount of matrix materials in coating film.The evaluation parameter was lag time.Experiments were done on the central composite design,and the data were simulated using multi-linear equation and second-order polynomial equation.The possibly optimal formulation was predicted by response surface method.The lag time of the tablets prepared under the optimum condition was compared with the predicted.Results The lag time was simulated using second-order polynomial equation and the regression coefficient was 0.993 7.The lag time in vitro of the tablets prepared under the optimum conditions was about 6 h,then drug released in pulsatilerelease character.Bias between the observed and predicted values of the lag time was within ?4.43%.Conclusion The sinomenine hydrochloride pulsatile tablets could release drug quickly in vitro at the predetermined time.Central composite design-response surface method can be used to optimize the formulation and the model developed in this study proves to be highly predictable.
