Vitamin B6 related epilepsy is a group of epileptic diseases,seizures in which could not be con-trolled by antiepileptic drugs,but could be controlled or obviously improved by vitamin B6 .It comprises of pyridoxine dependent epilepsy and pyridoxine responsive epilepsy predominantly,and the latter includes vitamin B6 responsive in-fantile spasms,pyridox(am)ine -5′-phosphate oxidase (PNPO)deficiency,hyperphosphatasia mental retardation syndrome (Mabry syndrome)and so on.The clinical presentations of the diseases above are nonspecific,manifesting as refractory seizures onset in neonatal or infantile period,which need to be distinguished from other diseases such as new-born hypoxic ischemic encephalopathy,Ohtahara syndrome and non -ketotic hyperglycinemia.Pyridoxine dependent epilepsy,PNPO deficiency and Mabry syndrome have relative specific biomarkers and known disease -causing genes, which are helpful for diagnosis.It is suggested that pyridoxine or pyridoxal phosphate should be tried first for all patients started seizures early (including all infantile spasms patients),avoiding missing these diseases.And once diagnosed,vi-tamin B6 should be maintained long -term or all the life according to the detailed disease.

Objective To study the proctective effect of heme oxygeanse-1(HO-1) on cirrhotic rats after hepatic ischemia reperfusion injury.Methods All the rats were randomly divided into 5 groups as follows: normal group(N),liver cirrhosis group(LC),sham operation group(S), ischemia reperfusion group(I/R),and I/R+hemin group.Except for N group,the other groups were injected with 40% CCl4 twice a week.After 11 weeks,the model of liver cirrhosis was formed.The segmental(70%) hepatic ischemia reperfusion operation was carried out one week later.The animals were sacrificed 6h after reperfusion.Blood was collected to measure the liver function,antioxidative ability,NF-?B and caspase-3,and HO-1 expressions were studied by immunohistochemistry method. Results Administration of hemin to induce high HO-1 expression could lessen hepatic injury,increase MnSOD enzyme level,and decrease caspase-3 and NF-?B expresssion.Conclusion HO-1 plays an important role in protecting liver cirrhosis against ischemia reperfusion injury by increasing MnSOD enzyme level and decreasing expression of caspase-3 and NF-?B.

Objective To study the protective effects of the polyphenols of vitis amurensis Rupr(PVAR) on rat heart mitochondria injury induced by oxygen radicals.Methods Experiment was designed into 5 groups:normal group,injury group and 25,50,100 mg?L-1PVAR+injury group.In experiment of rat heart mitochondria injury in vitro,vitamin C and FeSO4 played as an injury agent,PVAR played as a protective agent.The cardiolipin and MDA level of the mitochondria were determined.The membrane fluidity,ATPase activity and swelling of the mitochondria were examined.Results Compared with injury group,the cardiolipin was increased(P

BACKGROUND: There is yet no evidence about whether internal carotid artery stenting with cerebral protection devices is beneficial to reducing neurological complications. OBJECTIVE: To explore the safety and efficacy of carotid angioplasty and stenting with cerebral protection devices for carotid stenosis. DESIGN, TIME AND SETTING: Non-randomized concurrent control trial was performed at Hospital Affiliated to Medical College of Chinese People’s Armed Police Force from June 2005 to January 2007. PARTICIPANTS: Seventy-four patients with carotid artery stenosis underwent stenting, including 21 with cerebral protection devices (16 males and 5 females; average age of 66.4 years, range 50-79 years), and 53 with no protection devices (36 males and 17 females; average age of 69.2 years, range 52-83 years). METHODS: Size of cerebral protection devices was confirmed according to the diameter of normal vessel at distal carotid artery stenosis. The guide wire was sent into distal stenosis under guidance of pathway picture followed by cerebral protection device release. The stent passed over the stenosis and released to appropriate site. The protection device was removed when the stenosis was relieved confirmed by routine angiography. MAIN OUTCOME MEASURES: Features of stenting process; frequency of stroke attack perioperatively and during 12-month follow-up. All of them took periprocedual anticoagulation treatment, cerebral vascular angiograpgy. RESULTS: Seventy-six self-expandable stents were delivered in 74 patients with carotid stenosis. Twenty-one cerebral protection devices were employed including 8 Angioguard and 13 Filterwire. The patients without cerebral protection devices were predilated 20 times (37.7%) with the balloons, and all were postdilated; 3 cases (5.6%) developed brief decreased heart rate and hypotension after stent release. The patients with cerebral protection devices were predilated 6 times (28.5%) with balloons, and all were postdilated; 2 cased (9.5%) developed brief decreased heart rate and hypotension after stent release and 2 (9.5%) developed angiospasm. One patient (4.7%) with cerebral protection devices had cerebral infarction (4.7%) perioperatively and another had cerebral infarction (4.7%) during the follow up. While four patients in the group without cerebral protection devices had cerebral infarction (7.5%) perioperatively, and five had cerebral infarction (9.4%) during the follow up. There were no significant differences between two groups. CONCLUSION: The results of the study show that cerebral protection devices are not helpful to reduce neurological complications in patients with carotid artery stenosis after stenting.

Intravenous thrombolysis is the only treatment that has the evidence of evidence-based medicine in acute ischemic stroke. However, the narrow time window has limited the treatment opportunities of many patients. Transcranial ultrasound thrombolysis is a very promising thrombolysis-assisted method, and transcranial ultrasound plus microbubble-assisted thrombolysis is the research hotspot in recent years. At present, more suitable ultrasonic instruments for thrombolysis and a number of ways of ultrasound-assisted thrombolysis are being developed.

Objective To study the relationship between EZH2 and Ki-67 expression and both in ameloblastoma and normal oral mucosa.Methods EZH2 and Ki-67 were detected by immunohistochemical SP method in 50 cases of ameloblastoma (30 cases primary,20 cases recurrence) and expression in 20 cases of normal oral mucosa.Results The positive expression of EZH2 protein in recurrent ameloblastoma was (36.25±7.24) ％,significantly higher than that of primary ameloblastomas (25.26±4.28) ％ (P ＜ 0.001).Ki-67 in recurrent positive expression in ameloblastoma was (34.96±5.28) ％,significantly higher than that of primary ameloblastomas (29.68±3.27) ％ (P ＜ 0.05).There was positively corTelated on EZH2 and Ki-67 (P ＜ 0.05),but not on the size of tumor and gender (P ＞ 0.05).Conclusions There are high expression of EZH2 and Ki-67 in ameloblastoma,and their play key role in the occurrence and development of ameloblastoma.They can be used as a reference index for the prognosis.The combined detection of EZH2 and Ki-67 protein expression with clinical evidence and its prognosis may contribute to the process of ameloblastoma and recurrence.

The corneal transparency is one of the important basic conditions for realizing normal physiological functions of visual organs. Also corneal endothelial cells are important conditions for maintaining normal corneal transparency. Therefore, only to ensure the morphology and physiological integrity of the corneal endothelial, can have normal vision. However, intraocular surgeries inevitably cause damage to corneal endothelial cells. This paper will review the effects of glaucoma surgery on corneal endothelial cells.
