Objective:To explore the therapeutic effects of different anticoagulant therapies on intracranial venous si-nus thrombosis.Methods:A total of 150 patients with intracranial venous sinus thrombosis in our hospital from Jan 2011 to Jun 2013 were selected.According to random number method,they were divided into low molecular weight heparin (LMWH)group (n=50),unfractionated heparin group (UFH group,n=50)and interventional thrombol-ysis group (n=50,received interventional thrombolysis,patients received LMWH anticoagulant therapy after their conditions were stable).Therapeutic effects and incidences of complications were observed and compared among three groups.Results:After three-month treatment,total effective rate of interventional thrombolysis group was significantly higher than those of LMWH group and UFH group (98% vs.82.0% vs.72.0%),P <0.05 or <0.01;compared with LMWH group and UFH group,there were significant reductions in Rankin scale (mRS)score [(1.3 ±0.3)scores,(1.6±0.4)scores vs.(1.0±0.2)scores]and incidence rate of adverse reactions (16.0%,18.0%vs.4.0%)in interventional thrombolysis group (P <0.05 or <0.01),and there were no significant difference be-tween LMWH group and UFH group (P >0.05).Conclusion:Anticoagulant therapeutic effect of LMWH is better than that of UFH,but pure anticoagulant therapy cannot relieve patient′s condition completely.Interventional thrombolysis combined anticoagulant therapy possess good therapeutic effect,which is worthy of extension in clinic.

This experiment was based on a full-length SAMDC sequence from the drought stress induced cDNA library of Cleistogenes songorica.Two methods,absolute quantification and relative quantification,were used to analyze the gene expression under different tissue and drought stress treatment by real-time quantitaive PCR experiments and were compared each other,while CsSAMDC gene was used as a case.Leaves and roots tissue were sampled from the plants at 0,4,6,8,and 10 d of drought stress and 1 and 4 d after rewatering.The 2-CT method was used to analyze the relative changes in gene expression from quantitative real-time PCR experiments.A standard curve was generated by the purified plasmid DNA.The primer concentration in the realtime PCR was optimized.All absolute quatification data were normalized by the normalization factor from the most stable house-keeping genes in C.songorica.Relative quantification results using 2-CT method showed that CsSAMDC transcripts increased 5.93?0.71 fold in roots,down regulated 0.62?0.13 fold in leaves,under drought stress.Absolute quantification results showed that CsSAMDC transcripts up-regulated in roots significantly under drought stress as 1ong as 8 to 1 0 days after drought stress,while down-regulated in both roots and leaves after drought stress within 6 days and 1 to 4 days after rewatering,compared with control.CsSAMDC transcipt showed similar tendency of gene expression compared by using relative and absolute quantification methods.

In Alzheimer's disease there is obvious evidence of insulin resistance in the brain. Thiazolidinediones,a kind of insulin sensitizer,not only improves insulin sensitivity,but also decreases inflammation,promotes release and clearance of?-amyloid protein,all are beneficial to the improvement of memory.

Objective To observe the clinical effects of hyperbaric oxygen combined large dose ganglioside on delayed encephalopathy after acute carbon monoxide poisoning(DEACMP).Methods A totol of 72 patients of DEACMP were randomly divided into the observation group(37)and the control group(35).The patients of control group were given the routine treatment with hyperbaric oxygen.In the treatment group patients were given large doses of gangliosides 100 mg,1 times a day,for a period of 20 to 30 days additionally to the routine treatment of hyperbaric oxygen.All patients were examined before and after treatment in EEG examination (EEG),mini-mental state examination(MMSE).Results The abnormal rate of EEG was 37.83％(14/37) in the control group,which was significantly lower than that of 65.71％(23/35) in the treatment group((x2 =5.60,P ＜ 0.05).In the treatment group,the MMSE was(15.45±2.93) and(23.70±2.13) before and after treatment,respectively; in the control group,the MMSE was(14.88±2.84) and(20.33±2.09) before and after treatment.The MMSE was significantly impoved after treatment in both group(t =3.18 and 2.91,Ps ＜0.05).Furthermore,the MMSE impoved more significantly in the treatment group compared to the control group (t =6.28,P ＜ 0.05).The effective rate of treatment group was 86.48％(32/37),which was significantly higher than that of 51.43％(20/35) in the control group(x2 =7.72,P ＜ 0.01).Conclusion Application of large dose ganglioside treatment had significant clinical effects in delayed encephalopathy after acute car-bon monoxide poisoning,which is better than the effect of routine hyperbaric oxygen treatment.

BACKGROUND: Absorbable material is a hotspot in orthopedics, which is biodegradable, avoids fixation residues and second surgical trauma compared with the traditional internal fixation.OBJECTIVE: To investigate the clinical efficacy and safety of K-wires, screws and absorbable rods for the internal fixation of Mason II-III radial head fractures.METHODS: Totally 45 patients with Mason Ⅱ-Ⅲ radial head fractures were collected from January 2010 to December 2015 admited in Zhangjiagang First People's Hospital and Zhangjiagang Hospital of Traditional Chinese Medicine, and were then divided into three groups (n=15 per group), followed by implanted with K-wires (group A), screws (group B)and absorbable rods (group C), respectively. The baseline data, operation time, blood loss, healing time, Mayo and Broberg-Morrey scores were compared among groups.RESULTS AND CONCLUSION: (1) There were no significant differences in the baseline data, operation time, blood loss,and healing time among groups (P > 0.05). (2) The Mayo scores in the groups A, B, and C were (88.45±6.22),(92.37±5.60), and (90.82±6.58), respectively; the Broberg-Morrey scores in the groups A, B, and C group were ((90.82±6.83), (93.05±6.54), and (91.68±7.15), respectively; all above scores showed no significant differences among groups (P > 0.05). (4) The total incidence rate of complications in the groups A, B, and C was 20％ (2/15), 13％ (2/15),and 7％ (1/15) respectively, showing no significant difference among groups (P > 0.05). (4) These results indicate that the absorbable rods can obtain satisfactory treatment outcomes for Mason II-III radial head fractures, which is equivalent to the traditional internal fixation. Moreover, it can avoid secondary operation for removing internal fixators and the adverse impact of stress shielding, so it is recommended to be used in clinic.

Objective To investigate the changes and pathogenic significance of serum interleukin-12p70 (IL-12), intefferon-γ,(IFN-γ) and IL-4 in the course of hemorrhagic fever with renal syndrome(HFRS). Methods Twenty five eases were divided into mild group (14 eases) and severe group (11 cases) according to the severity of illness. Blood samples were collected in various stages(fever, hypotensian and oliguria,diuresis stage). Serum IL-12 and IFN-γ levels were determined by enzyme-linked immunoserbent assay(ELISA), IL-4 by radioimmunoassay (RIA), blood urea nitrogen (BUN) and platelet by automatic biochemical analyzer and blood analyzer. Results Serum IL-12 levels in mild and severe groups were significantly different during various stages of HFRS (F=5.765, P<0.01). The IL-12 level of both patient groups significantly increased(P<0.01) in fever[ (0.87±0.38), (1.08± 0.77)μg/L], hypotension and oliguria [ (0.77±0.21), (2.11±2.13)μg/L] ,and diuresis stage [ (1.42±1.10), (1.20±0.88)μg/L], compared with control group [(0.56±0.10)μg/L]. In various stages, IFN-γ levels of both case groups were respectively (8.04±13.05), (5.94±8.24), (15.95±18.05), (4.41±4.10), (1.09±1.24), (1.38±1.74), (1.12±1.26), (0.19±1.29)μg/L, and the difference was statistically significant compared with control [ (0.27±0.15)rig/L]. K,-4 levels did not change significantly in the stages(F=0.682, P0.05), while the ratios of IFN-γ and IL-4 contents in mild and severe cases were significantly higher than control [(0.36±0.26) μg/L] in fever[ (2.46±3.52), (16.92±22.77)p.g/L], hypotension and oliguria[(2.52±2.72), (1.77±2.06) μg/L],diuresis stage [(1.45±2.28), (2.32±3.98)μg/L], the difference had statically significant (P<0.05 or 0.01).The curve of IL-12 was similar to that of BUN, but was contrary to blood platelet count. Conclusions The elevated levels of IL-12 and IFN-γ, with the imbalance of Th1/Th2 might be the main cause of systemic inflammatoryresponse and involved in the pathogenesis of HFRS.

Objective To assess the various features of Budd-Chiari syndrome(BCS)on three- dimensional contrast-enhanced magnetic resonance angiography(3D CE MRA)and to evaluate the potential value of this new technique.Methods Thirty-three patients with BCS underwent 3D CE MRA examination. In 23 cases,BCS was secondary to hepatocellular carcinoma(21 patients)or right adrenal carcinoma (1 patient)or thrombophlebitis(1 patient).Ten patients had primary BCS.The patency of the hepatic veins,inferior vena cava(IVC)and portal veins were assessed.The presence of intra-and extrahepatic collaterals,liver parenchymal abnormalities and porto-systemic varices were evaluated.The diagnosis on 3D CE MRA was correlated with that on inferior vena cavography and right hepatic venography,which were available in 10 and 2 cases respectively.Results Various features of BCS were displayed on 3D CE MRA. Hepatic venous findings included tumor thrombosis(19 patients),tumor compression(2 patients), nonvisualization(4 patients)and focal stenosis(4 patients)of the hepatic veins.IVC findings were severe stenosis or occlusion(10 cases),tumor direct invasion(2 cases),tumor thrombosis(3 cases), thrombophlebitis(1 case)and web formation(3 cases).Intrahepatic collaterals were demonstrated in 9 patients including 2 with "spider web" sign.Detected extrahepatic collaterals included dilated azygos and hemiazygos veins(13 cases)and left renal-inferior phrenic-pericardiophrenic collaterals(2 cases).The occlusion of the left portal vein and the presence of porto-systemic varices were depicted in 2 and 10 patients respectively.Liver parenchymal abnormalities identified by 3D CE MRA consisted of caudate lobe enlargement(7 cases),heterogenous enhancement(18 cases)and associated tumors(18 cases). Compared with inferior vena cavography and hepatic venography,the accuracy of 3D CE MRA in the diagnosis of IVC obstruction or hepatic venous stenosis was 100%.Conclusion 3D CE MRA can display various features of BCS and has the potential to provide an accurate diagnosis.

AIM:To explore the association of the mutation in PPP2R3A exons and retinoblastoma.METHODS:Hospital-based case control study was taken.Retinoblastoma patients (15 cases, as case group) and matched controls (30 controls, as control group) were recruited in this study.Genomic DNA obtained from formalin fixed paraffin embedded (FFPE) and peripheral blood were used as template.PPP2R3A gene exon sequences were detected by PCR-sequencing.Homology analysis was performed using blastn in GenBank.RESULTS:Analyzing PPP2R3A DNA sequences (1001bp) from 15 cases, two reported SNPs had been detected, including rs34629706 and rs144802055.Rs34629706 also occurred in the control group.Rs144802055 appeared only in the case group.CONCLUSION:PPP2R3A gene SNPs of rs34629706 is unrelated to the incidence of retinoblastoma.Relations between rs144802055 and RB needs to be further explored.
