Objective To investigate the expression of H1 protein in the prefrontal cortex of comatose rats which have suffered traumatic brain injury (TBI) after electrical stimulation of the median nerve (MNS).Methods Seventy-two Sprague-Dawley rats (weighing 250 to 300 g) were randomly divided into a stimulated group (MNS+ TBI),an antagonist group (MNS+TBI+OXR1 antagonist),a model group (TBI) and a control group,with 18 rats in each group.Traumatic brain injury was modeled in all of the rats except those of the control group.After the modeling,the stimulated group was given MNS,the antagonist group was provided with MNS and an OXR1 injection,and the model group was given MNS with a current intensity of 0.One hour after the experiment,the consciousness of each rat was evaluated using a double-blind method.Animals were sacrificed at 6,12 and 24 hours after the intervention and brain tissue was removed.H1 protein expression was examined using immunohistochemistry.Results One hour after the experiment,significant differences were observed in the consciousness of the 4 groups,with the 18 rats of the control group on consciousness level one.Thirteen rats in the stimulated group exhibited a righting reflex,compared with 9 in the antagonist group and 5 in the model group.Immunohistochemistry showed that H1 expression was strongest in the stimulated group,followed by the antagonist,control and model groups.The H1 expression was highest at 24 hours after the experiment,followed by that at 6 h and 12 h,but those differences were not statistically significant.Conclusion Median nerve electrical stimulation might modulate wakefulness after traumatic brain injury by promoting H1 expression via orexin-A in the prefrontal contex.

Objective:To investigate the expression of 5-HT 2A receptor in the prefrontal cortex of traumatic brain injuryinduced coma rats after median nerve electrical stimulation.Method:A total of 72 SD rats (weighing 250-300g) were randomly divided into 4 groups:a stimulationgroup,an antagonist group,a sham-stimulation group and a control group.This traumatic brain injury model was established by a weight-drop head injury,and we evaluated the change of behavior through the six classical levels of consciousness.The animals were sacrificed and their brain tissues were removed at 6,12,and 24 hours after injury.5-HT 2A protein expression was examined by immunohistochemistry.Result:Thirteen rats exhibited righting reflex in the stimulation group.In the antagonist group,9 rats exhibited righting reflex.5 rats in the sham-stimulation group had the same response.The mean rank of consciousness degree were degree 9.50 in the control group,degree 52.75 in the sham-stimulation group,degree 37.61 in the stimulation group,degree 46.14 in the antagonist group.Comparison among groups presented an increasing consciousness degree:control group＜stimulation group＜antagonist group＜sham-stimulation group(P＜0.01).Resuits from immunohistochemistry showed that significant differences in the 5-HT 2A expression among the four groups (sham-stimulation＜control＜antagonist＜stimulation))(P＜0.05),and a within-group comparison showed that the 5-HT 2A expression level was as follows:6 hours＜24 hours ＜12 hours(P＜0.05).Conclusion:Median nerve electrical stimulation might modulate wakefulness by promoting the 5-HT 2A expression via orexin-A in the prefrontal cortex of rats with traumatic brain injury-induced coma.

blood stasis vessel obstruction syndrome among all cases,occupying 40.91%,31.31% and 13.89% respectively;the groups of damp-heat of liver and gall and stagnation of the liver Qi and deficiency of the spleen have very active replication of virus;however,insufficiency of both the spleen and the kidney are in lower-lever replication.[Conclusion]There is significant correlation between damp-heat of liver and gall and stagnation of the liver Qi and deficiency of the spleen and activity replication of HBV.In Chronic Hepatitis B,the dampness has a close relation with HBV.

The morbidity and mortality of cardiovascular diseases(CVD)are still high in our country,they severely threaten peopleS health and quality of life.A dysregulated or reduced autophagy is associated with ischemic heart disease,cardiac hypertrophy,heart failure and arrhythmia.Autophagy is a key regulator in CVD development,and is essential for maintenance of heart function and improvement of prognosis.Thus,modulating autophagy represents an attractive future therapeutic target for treating cardiovascular disease.This article reviewed the research progression about effects of autophagy on ischemic heart disease,cardiac hypertrophy,heart failure and arrhythmia.

This article introduced the biological characteristics of N-methyl-D-aspartate (NMDA), and reviewed the relationship be-tween NMDA receptor and neurological disease, including cerebral trauma, cerebral ischemia, epilepsy, neuropathic pain, depression and Al-zheimer disease.

Castration-resistant prostate cancer is a fatal disease with rapid progress. This malignancy usually presents with metastasis and poor prognosis. This type of disease also often causes 100%mortality, of which the median survival time is less than 20 months. Thus, treatment of castration-resistant prostate cancer remains challenging, and the underlying mechanisms of this cancer have yet to be identified. Several new therapies for castration-resistant prostate cancer have been proposed, such as androgen receptor antago-nists, immunotherapeutic drugs, taxanes, antiangiogenic agents, radionuclides, and bone-targeting drugs. These therapies can im-prove the survival time of patients. The advances in the treatment of castration-resistant prostate cancer are briefly reviewed in this ar-ticle.

With the development of modern society,children get more and more attention from their parents.However,this situation often leads to parents' overprotection during their child-raising,especially when they have a child with pediatric diseases.Parents' inappropriate parenting may even affect the prognosis and outcome of their children's disease.According to recent studies about parenting of pediatric disease children,the parents would inevitably take overprotection,which might affect children's physical and mental health.Therefore,It is recommended that parents should correctly understand the diseases and their children,and choose appropriate parenting.

AIM: To evaluate the clinical effects of modified hydroxyapatite implant in scleral shell.
METHODS: Thirty - four cases were performed eye evisceration, autogenous sclera shell anterior and posterior petaloid shape with posterior sclera fenestration, hydroxyapatite artificial eyeballs were implanted at stage I, and conjunctival wound, orbital activity and other complications were observed after surgery.
RESULTS:The follow-up was 6 ~12mo. There was no patients with implant exposure, sclera dissolution, conjunctival wound dehiscence, conjunctival sac constriction noted. All the patients got good activity of artificial globe, and the active range of side motion of the HA was 10o ~15o. The artificial eyes looked symmetrical, and the eyes socket were full.
CONCLUSION: The modified hydroxyapatite implant in scleral shell can maintain the normal anatomy of the orbital tissue, and also can get full eyes socket and good activity, It was an easy and simple surgery which could obtain satisfactory clinical effect and less complications.
