Ischemic stroke is an important cause of death and disability.Hemorrhagic transformation (HT) is a serious complication of acute ischemic stroke,especially in patients receiving intravenous thrombolytic therapy.Identifying patients at high risk of HT is very important for improving stroke outcomes.Some studied have shown that several serum biomarkers can be used to predict HT risk in patients with acute ischemic stroke.This article reviews the serum biomarkers of HT after acute ischemic stroke.

Objectives To analyze the relationship between the multi-organ hypoxia damage and the death of acute high altitude sickness severe case. Methods 3220 cases from 1956. 06 to 2005.06 in the hospital were reviewed by questionnaire and the cases in MODS or death were screened out. The cause of death and feature were analyzed by the data as clinical symptom, physical signs and auxiliary examination. Results 281 cases complicated by MODS (include 35 dead cases) were found out by review. The incidence with MODS is 8.73% , and the death rate was 1.09%. The masculine incidence rate of the clinical symptom, physical signs and auxiliary examination in death were 2. 86% ~65. 71% , 2. 86% ~ 100% and 14. 29% ~ 100% , respectively. The MODS incidence in dead cases was 100%. Compared with the curing group, the MODS number, cardiac functional disturbance, brain disorder and renal functional disturbance in the death group had a significantly high incidence rate in all the 281 cases with MODS( P <0.05). With dependability analysis, there were a significantly direct correlation relationship between the death in the severe cases with acute high altitude sickness and the number of MODS ( r = 0. 3473, P < 0.001). Conclusion Hypoxia to the damage of multi-organ function play an important role in death of the severe cases with acute high altitude sickness in high attitude area, and the functional disturbance of important organs as heart, brain and kidney is the most important cause to death.

Objective To explore the preparation of specific immune RMA(iRNA) on anti-rabies and further study immunotherapy of rabies virus exposure. Methods Horses were immunized with the rabi-es virus and their livers were isolated from the horse of antiserum, from which total RNA was extracted and purified by sodium lauryisulfonate, phenol, chloroform, ethyiene glycol monomethyl ether, cetyltrimethyam-moniumbromide and alcohol. Results Pure preparation physico-chemical characterization was analyzed, and it's weight was 0.15% of weight of liver. The RNA contained 2.86% DNA and 1.16% protein. The iRNA with a maximum UV absorbance at 258 nm and A_(258/280) about 2.0. The test of RNA was positive, which had a relative molecular mas of 13.7×10~3 by high performance liquid chromatography(HPLC), and its hy-perchromic effect was 50.67%. The vesults of biological activity was showed that the rate of leucocyte adher-ence inhibition(LAI) was 41.73%, The protective rate was 50% and prolonging the life was 31.62%. Conclusion The results obtained with the practical value were identical and provide a basis on medicines of anti-rabies.

Electrolyte disturbance was prominent in patients with severe acute mountain sickness. In these patients hypoxia caused water and salt retension together with vasoactive substances and excessive free radicals might play important roles in the development of multiple organ dysfunction syndrome (MODS). More attention should be given to electrolyte monitoring in dealing with these severe mountain sickness in field.

[Abstract ] Objective Chronic renal disease,a common and frequent disease,is the most cause inducing chronic renal failure. There is an important guiding significance for renal biopsy in the diagnosis,treatment and prognosis of renal disease.The aim of this study was to analyze the characteristics of renal biopsy and the relation between pathological types and clinical presentation in Tibet. Methods Between June 2011 and December 2013 in General Hospital of Tibetan Military Command, Lhasa, percutaneous renal biopsy were per-formed in 107 renal patients.In this study, the gender, age, pathologic entities, and clinical manifestation were analyzed retrospectively. The final diagnosis was made by the clinical manifestation, laboratory examination,and pathologic results. Results The mean age at renal biopsy was 29.8 ±12.2(10~66)years in 47 male cases (43.9%) and 69 female cases (56.1%).This includes 75 Tibetan cases (70.1%), 31 Han cases (28.9%), and Bai cases (1.0%).The primary glomerular disease was 95.3%and the secondary glomerular disease was 4.7%in the total 107 cases.Fourty-four point three percent of the primary glomerular disease were male cases and 100%of secondary glomerular disease were female cases.The main pathological type of the primary glomerular disease was podocyte nephropathy (43.9%), followed by membranous nephropathy (18.7%), IgA nephropathy (11.2%), focal segmental glomerulosclerosis (9.3%) and mesangiocapillary glomerulonephritis (5.6%).The clinical manifestations of 107 cases were classified as syndrome of nephrotic syn-dromn(69.1%),urinary abnormalities(14.9%),isolated macrographic haematuria (3.7%),chronic renal failure(2.8%).Among the nephrotic syndrome,podocyte disease was 63.5%,membranous glomerulopathy was 18.9%,focal segmental glomeruolsclerosis was 8.1%,and membranoproliferative glomerulonephritis was 5.4%. Conclusion The primary glomerulonephritis was the most common glomerular diseases at high altitude area in Tibet.The most frequent type of pri-mary glomerular nephritis was podocyte disease, and the most frequent type of secondary glomerular nephritis was Henoch-Schonlein purpura glomerulonephritis.

Objective To study the analysis of folic acid combined with vitamin for level two ischemic stroke prevention effect. Methods From April 2013 to January 2014 in our hospital , selected the patients with stroke in 100 cases as the research object. In digital method were randomly divided into observation group (50 cases) and control group (50 cases). The patients in the observation group was taken folic acid combined with vitamin , the control group only was given vitamins, in all patients on admission and at discharge on the plasma levels of Hcy, D-two dimer, fibrinogen, three glycerol, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol level, the effect of folic acid combined with the vitamin was observed. Results No significant differences between the two groups before treatment, plasma Hcy levels (P>0.05) in different ways, the observation group after treatment, the plasma Hcy levels were significantly lower than the control group , with significant difference ( P<0 . 05 ) . Two groups by different ways of treatment, the observation group was best accounted for 70% (35/50), the excellent and good rate was as high as 98% (49/50), significantly higher than the control group 44% (22/50) and 74% (37/50), with significant difference (P<0.05). On two groups of different ways of treatment of cerebral was stroke recurrence and score in patients with SIAS were compared, the recurrence rate of the observation group was lower than the control group, with significant difference (P<0.05), the SIAS score was significantly higher than that of the control group, with significant difference (P<0.05). Conclusion For the patients with stroke, should the use of folic acid combine with vitamin two level of prevention. The combine uses of folic acid and vitamin , can effectively reduce the incidence of stroke and recurrence rate.
