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.

Diseases of glucose and lipid metabolism disorder,presented rather complicated pathological mechanism,often with clinical pattern of multiple concurrent diseases.Therefore,the traditional single-disease based on treatment methods need improving.In view of plenty of clinical practice,theatrical and fundamental researches,the pathological mechanisms of some chronic disorders,such as hyperlipidemia,nonalcoholic fatty liver disease,type 2 diabetes,hypertension,atherosclerosis and severe cardiovascular complications,resulted from the impairment in the metabolism of glucose and lipid were investigated using the method of integrated Chinese and western medicine.Overall,the features of these diseases and their common characteristics were discovered,and accordingly we defined the new concept of glucolipid metabolic disease (GLMD) and put forward the concept of pivot liver of metabolic regulation system.In addition,we developed the therapeutic strategy of modulating liver,starting pivot and cleaning turbidity,for the comprehensive and integrated treatment and prevention of these diseases.The theory of GLMD shared the critical characteristics with precision medicine,taking its own specialty.Finally,the content and approaches for the research of GLMD were proposed,and some essential and core fields in the precision medical research for GLMD were profoundly analyzed and prospected.

Objective To explore the clinical effect of single use or combination of dydrogesterone and progestin in treatment of threatened abortion caused by uteal phase defect.Methods Totally 186 patients with threatened abortion caused by uteal phase defect accepted in The First Affiliated Hospital of Henan from April 2015 to April 2016 were selected and randomly divided into groups A,B,and C with 62 cases in each group.Patients in group A were given dydrogesterone,those in group B were given progestin,and those in group C were given dydrogesterone combined with progestin.Then the clinical effect,expression of hormones,treatment outcome,and adverse reaction were observed and compared.Results The total effective rates of groups A and B were 72.58％ and 66.13％,respectively,which were obviously lower than 90.32％ of group C with statistically significance (P ＜0.05).The expression levels of P,E2,and hCG of three groups after treatment were higher than those before,those in group C were the highest among them (P ＜ 0.05).The successful treatment rates of groups A,B,and C were 83.87％,82.26％,and 95.16％,respectively,which had no great difference.Conclusion Combination use of dydrogesterone and progestin has better effective rate in treatment of threatened abortion caused by uteal phase defect compared to single use of these two drugs,which has good safety and worth of clinical application.

Objective To assess the relationship between serum uric acid (SUA)and metabolic syndrome and coronary artery disease(CAD).Methods 232 untreated subjects with essential hypertension were divided into two groups(CAD and no CAD)by coronary angiography.All subjects were free of myocardial infarction,cardiomyopathy,valvular disease, atrial fibrillation,aortic dissection,and renal disease.Results Compared to no CAD group,age,diabetes,triglycerides and SUA in CAD group were higher.There was a significant association between SUA and the severity of CAD (P=0. 015).However,after adjustment for concomitant risk factors of cardiovascular disease,SUA was not an independent risk factor of CAD(P=0.151).In sex-specific analysis,there was a trend of SUA to be an independent risk factor of CAD in women(P=0.062),but it was no statistic significance.The highest quartile level of $UA tended to be associated with increased risk for CAD,but it was not statistically significant either(OR=2.52,P=0.075).SUA was closely associated with metabolic syndrome and diabetes in woman.Conclusion In untreated patients with essential hyperteusion,SUA was associated with metabolic syndrome and the severity of CAD,but it is not an independent risk factor of CAD,the raised SUA may be only a marker of insulin resistance.

Objective To isolate and culture human adipose-derived stem cells (hADSCs),investigate the influence of hADSCs on the cellular morphology,survival rate,and function of human islet cells under the in vitro non-contact co-culture conditions,and explore its mechanism.Method hADSCs were isolated by collagenase digestion method,then cultured,and identified by morphology,immunofluorescence and multi-directional differentiation.Adult islet cells were separated and purified by Liberase enzyme and Ficoll 400,then divided into co-culture group and individual group.The cellular growth morphology of islet cells was observed by inverted phase contrast microscope.The survival rate of islet cells,insulin secretory volume,insulin stimulation index and concentration of growth factor in the supernatant were compared between the two groups.Result hADSCs of the third generation showed uniform long spindle fibrocyte-like morphology,and had multi-directional differentiational potentials of osteogenesis and adipogenesis.Immunofluorescence test of surface antigens on hADSCs revealed CD44 + and CD49d +,CD31-,CD34-and CD106-.After 14-day culture,the islet cellular morphology in co-culture group was more intact than that in individual group.The survival rate of islet cells in co-culture group was (82.83 + 2.32) ％,and that in individual group was (53.00 + 2.82) ％ (P＜0.01).Insulin secretory volumes were (23.66 + 2.11) and (7.82 +1.09) mU/L respectively in co-culture group and individual group under high glucose concentration,and 13.22 + 0.77 and 6.40 + 0.44 mU/L respectively under low glucose concentration (P＜0.01 for all).Insulin stimulation index was decreased from 1.67 + 0.10 (at 3rd day) to 1.77 + 0.13 (at 14th day) in co-culture group,and from (1.67 + 0.10) (at 3rd day) to (1.77 + 0.13) (at 14th day) in individual group (P＜0.01).After 14-day culture,the concentrations of HGF,TGF-β,VEGF and bFGF in the supernatant were higher in co-culture group than in individual group (P＜0.01).Conclusion hADSCs were isolated and cultured successfully from adult adipose tissue.They could increase the survival rate and improve the function of islet cells when co-culture with the adult islet cells in vitro through secreting HGF,TGF-β,VEGF and b-FGF.

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.
