Objective This study is to explore the infratentoriat-supracerebellar keyhole approach for microsurgical treatment of pineal region tumors and to evaluate its curative efficacy and safety.Methods According to hi-fi quality MRI images,individual operation schemes were designed.Microsurgical infratentori- al-supracerebellar keyhole approach was used to resect lesions in 7 consecutive patients with prone postition.A 2.0 cm?2.5 cm surgical bone window was performed with its superior margin reaching to the inferior margin of the transverse sinus and confluence sinus.Results Among the 7 pineal region tumors,there were 2 ger- minomas,2 pineocytomas,1 pineoblastoma,1 glioma and 1 chlesteatoma.All cases were re-examined with MRI after operation and it was found that 6 lesions were totally removed and 1 was subtotally removed.The outcome of the treatment was satisfying.There was no infection,bleeding or death after surgery.The follow-up result in the near future was good.Conclusion The infratentorial-supracerebellar keyhole approach for the excision of pineal region tumors was proved to be a satisfactory means with a total removal rate,an excellent curative effect and small surgical trauma.

Objective To observe the effect of revascularization on left ventricular remodelling and function in patients with myocardial infarction (MI) Methods Two hundred MI patients were studied The patients receiving revascularization were defined as group one, and those receiving medical treatment were defined as group two The structure, systolic and diastolic function index of the heart were measured by Doppler Echocardiography Results In revascularized group, LA, LAV, LVD, LVS were significantly decreased And EDV, EDVI, ESV, ESVI were much better than those in medical treatment group ( P

ObjectiveTo master the epidemic situation of drinking-water borne endemic fluorosis in Xinzhou,evaluate the effects of water improvement project to reduce fluoride,and to provide a timely scientific basis for monitoring the disease and for establishment of preventive countermeasures.MethodsAccording to the water fluoride concentration and type of the disease,after stratification 25 endemic villages were selected as survey points.Five water samples were collected in water unimproved monitoring villages according to water well locations of east,west,south,north and center.In monitoring villages with improved water,3 tap water and 1 source water samples were collected,respectively.The fluorine content in water samples was determined according to the “Standard Testing Methods for Drinking Water”(GB/T 5750-2006).All children aged 8 to 12 of the survey villages were examined for dental fluorosis by Dean method.Clinical osteofluorosis of all the resident over the age of 16 was examined,8 villages of these counties were selected,10 men and.women were randomly selected in each village,respectively,and they were examined again by X-ray using “Diagnostic Criteria of Endemic Skeletal Fluorosis” (WS/T 192-2007).Children aged 8 to 12 in 13 villages of chosen villages were selected for urine collection,6 unne samples were collected in each age group and a total of 30 samples were collected,and urinary fluoride was determined by F-ion selective electrode method(WS/T 89-2006).ResultsA total of 56 water samples were tested in water-unimproved villages,the average water fluorine was 2.7 mg/L And 52 water samples were tested in waterimproved villages,the average water fluorine was 1.6 mg/L,water fluoride content ＞ 1.5 mg/L accounted for 46.15％ (6/13) in the water-improved village.Incidences of dental fluorosis of children in the water-unimproved villages and water-improved villages were 74.75％ (622/832) and 23.67％ (241/1018),respectively.The difference was statistically significant(x2 =140,P ＜ 0.01).The prevalence rate of skeletal fluorosis was 30.02％(2803/9335) in water-unimproved villages,and 9.44％ (1230/13 022) in water-improved villages.The difference was statistically significant(x2 =1557.75,P ＜ 0.01 ).The mean of urine fluorine in a total sample was 3.31 mg/L,the urinary fluoride concentration of children in water-improved villages was significantly different from that of water-unimproved villages(t =2.27,P ＜ 0.05).ConclusionsBy reducing fluorine and improving drinking water,disease in drinkingwater borne endemic fluorosis areas in Xinzhou has been controlled to a certain degree.However,the disease is still very serious in some endemic areas.Fluoride in drinking water re-increases in some water-improved villages,the disease is also in a rise.So,the work of monitoring and prevention should be strengthened.

·Uveitis is an inflammation of any or all parts of the uveal tract including the iris, ciliary body and the choroid. Despite current advances in diagnosis and management, visual loss occurs in 35%-45% of patients with uveitis. The etiopathogenesis of uveitis remains unknown; it may be associated with environmental and immunogenetic factors. Many studies have demonstrated polymorphisms in major histocompatibility complex (MHC) genes may determine involvement in uveitis. Recently polymor-phisms in non-MHC genes, including cytokine and che-mokine genes, have been reported to play important roles in the pathogenesis of uveitis. This article reviewed the advances in the studies on cytokine and chemokine gene polymorphisms associated with uveitis.

Objective To observe the therapeutic effect of plum-blossom needle therapy and cupping therapy combined with traction on cervical spondylosis of vertebral artery type.Methods 60 patients with cervical spondylosis of vertebral artery type were randomly divided into the treatment group and control group with 30 cases in each group. The patients of the treatment group were treated with plum-blossom needle therapy and cupping therapy combined with traction, and those of the control group only with traction. The therapeutic effects of two groups were compared.Results The total effective rate of the treatment group was 83.3 %, that of the control group was 60.0%. There was a significant difference between two groups ( P<0.05).Conclusion The effect of plum-blossom needle therapy and cupping therapy combined with traction on cervical spondylosis of vertebral artery type is superior to traction therapy alone.

Objective To investigate the protective effects of ethanol-extract of Halenia elliptica D. Don on chemical hepatic injury in mice. Methods Mouse models of chemical hepatic injury were induced by intraperitoneal injection of 0.12 %CCL4. Extract of Halenia elliptica D. Don by alcohol was administered,and serum ALT,AST activities and liver glycogen level were measured in mice. Results Compared with the models,the enzyme activities of ALT and AST were significantly reduced and the content of liver glycogen was significantly increased in the ethanol-ex tract of Halenia elliptica groups. Conclusion It is indicated that ethanol-extract of Halenia elliptica D. Don has an effect in protecting the liver.
