Hemorrhage after prostate biopsy is common, but hemorrhagic shock is rare. We reported a case of sudden severe hematuria on the third day after prostate biopsy, which was considered to be bleeding at the puncture site. Conservative treatment was ineffective, and interventional embolization was performed. Bilateral bulbar urethral arteries were embolized, and the bleeding was stopped successfully. On the 4th day after embolization, the patient developed hypovolemic shock. Angiography showed bilateral prostatic artery bleeding, and the bleeding site and its superior branch arteries were embolized immediately. At 4 months after embolization, no bleeding related events occurred.

Objective To analyze the constituent of the 32 kD protein band and its expression in schizophrenia se?rum. Methods Sixty schizophrenia patients and 58 health controls were recruited. The serum samples were collected and precipitated with 7%PEG. The sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was used to ob?tain the abnormal 32 kD proteins band in patients. This protein band was cut and then analyzed using mass spectrometric technique. Results The 32 kD protein band was present in 38 schizophrenia patients but not in control and positive rate was 63.33%. The mass spectrometric analysis showed that 32 kD protein band contained 14 proteins ranging from 30 kD to 35 kD, including 6 high-frequency proteins (cDNA coded protein 1 and 2, Apolin protein A-1, Isoform 2 of ficolin-2, Complement factor H and clusterin) and 8 low-frequency proteins (IgG H chain, zinc-alphg-2-glycoprotein, fermitin,family apolin protein L-1, isoform 10 of collectin-1, purine nucleoside, anne xin and cDNA coded protein 3). Three cD?NA coded unknown proteins were highly similar to complement C4-B, β2-glycoprotein and erythrocyte band 7 integral membrane protein. Conclusion There is a unknown specific 32 kD protein that is consisted mainly of fourteen proteins in serum of schizophrenia.

Objective To investigate the association between gasification and duration and power of radiofrequency ablation in porcine muscle and liver and compare the effects in these tissues in an in vitro study. Methods Radiofrequency ablation was performed on fresh muscle and liver tissue,and the maximum cross-sectional volume of gasification was used to compare the effects according to duration and power of ablation. The experiment was repeated three times,and data were averaged. Results Within a certain range,gasification volume increased significantly with increases in ablation duration and power (P < 0.05). Gasification volumes differed significantly between tissues (P < 0.05). The gasification volume was smaller in muscle than in liver at 15 W and 30 W,while the affected volume in muscle was greater than in liver at 45 W (P < 0.05). Conclusion Under conditions of the same duration and power,the gasification volumes were different in muscle and liver. Therefore,the power and time required for maximum gasification in different tissues may be different.

Objective To understand the variation of arsenic concentration in underground water at the endemic arsenic poison disease area of Jianghan Plain so as to better understand the spatial distribution of high arsenic groundwater,hydro-chemical evolution and source of arsenic in this region.Methods Thirty underground water samples were collected respectively around 3 km radius of the two houses where arsenic poisoning patients lived,in Xiantao and Honghu.Sediment cores of three drillings were collected as well.Both paired t-test or paired Wilcoxon Signed Ranking Test were used to compare the arsenic concentration of water.Results The arsenic concentration in 2011-2012 appeared lower than that in 2006-2007 at the Nanhong village of Xiantao (t=4.645 3,P＜0.000 1),but was higher(S=-150,P＜0.000 1) in the Yaohe village of Honghu.The pH value showed weak acidity with Eh as weak oxidated.Positive correlations were observed between arsenic concentration and C1,HCO3-,Fe,Mn.However,negative correlations were found between As and SO42-,NO3-.The range of arsenic content in the sediment was 1.500 mg/kg to 17.289 mg/kg.The maximum arsenic content existed in the soil layer,while the minimum arsenic content existed in the sand layer.Conclusion The concentration of arsenic varied widely with time and space at endemic arsenic poison disease area of Jianghan Plain.Characteristics of these water chemicals showed significant differences,when compared to the groundwater from Datong Basin,Shanxi Shanyin and Hetao Plain of Inner Mongolia,which presented a typical environment with high arsenic contents in the groundwater.The arsenic content in the sediment samples seemed related to the lithologic structure.

Objective: To summarize the adverse effects of pegaspargase in the treatment of lymphoid malignancies and management experience. Methods: Clinical data of patients who received chemotherapy including pegaspargase in the Department of Hematology of Beijing Tongren hospital during August 2011 to December 2015 were retrospective analyzed, and the adverse effects of pegaspargase and the management experience was summarized. Results: A total of 129 patients with 443 times of pegaspargase used during this period. The common adverse reactions included allergic reactions in 2 cases (1.6%), acute pancreatitis in 19 (14.7%) including 6 acute symptomatic pancreatitis and 13 chemical pancreatitis with elevated pancreatin, hypertriglyceridemia in 15 cases(11.6%), hyperglycemia in 85 (65.9%), hypoglycemia in 7 (5.4%), elevated aminotransferase in 25 (19.4%), hyperbilirubinemia in 21 (15.5%), hypoalbuminemia in 62 (48.1%), prolonged APTT in 61 (47.3%), prolonged PT in 22 (17.1%), prolonged TT in 15 (11.6%), hypofibrinogen in 75 (58.1%), thrombus in 11 (8.5%) and bleeding in 3 (2.3%). The above adverse reactions were improved by symptomatic treatment of anti allergy, inhibition of secretion of pancreatic juice, lipid lowering, hypoglycemic, liver preservation, supplementation of plasma and hemostasis, respectively. Some serious adverse reactions affected the application of pegaspargase, even lead to discontinuation of the aspartate. Conclusion Though adverse effects associated with pegaspargase are extensive, most patients can successfully complete the chemotherapy containing the pegaspargase with close monitoring and timely treatment.

Objective To explore the effect of exercise on vascular smooth muscle cell(VSMC) phenotype switching in hypertensive arteries and to figure out the regulatory mechanisms of mircroRNA (miR)-143/145 on Akt signaling during the process.Methods Three-month old(Wistar Kyoto rats) WKY and (spontaneously hypertensive rats) SHR were divided into 4 groups:WKY-C,SHR-C,WKY-E,and SHR-E,which were subjected to 8wk moderate treadmill training (E) or sedentary as control (C) with blood pressure being monitored.After the last bout of exercise,mesenteric arteries were isolated to determine VSMC phenotypic marker,miR143/145 expression and Akt phosphorylation.In transfection experiment in vitro,miR-145 mimic and miR-145 inhibitor were transfected into cultured VSMC,and given immunofluorescent staining using α-actin to detect the cell morphology.VSMC phenotype marker,Akt phosphorylation,and mRNA expressions of the insulin-like growth factor Ⅰ receptor (IGF-IR),Insulin receptor substrate 1 antibody(IRS-1),and p70S6K were determined.Results The blood pressure of SHR-E reduced significantly compared with that of SHR-C(P＜0.05),and the arterial thicknessof SHR-E decreased significantly (P＜0.05).The VSMC contractile marker calponin in SHR-E increased significantly when compared with SHR-C(P＜0.05),while the proliferative marker osteoppontin (OPN) in SHR-E reduced significantly than that in SHR-C(P＜0.05).The miR-145 of SHR-E was significantly enhanced(P＜0.05),while there was no significant difference in the miR-143.The Akt of SHR-E was activated more significantly than SHR-C(P＜0.05).The miR-145 overexpression by transfecting miR-145 mimic into VSMC increased α-actin significantly(P＜0.05),while miR-145 inhibitor made α-actin a decrease.Akt activation was significantly inhibited by miR-145 mimic and enhanced by miR-145 inhibitor(P＜0.05).The miR-145 significantly inhibited IRS-1 and IGF-1R mRNA(P＜ 0.05),but the targeting effects were not significant on p70S6K mRNA.Conclusions Exercise ameliorates the high blood pressure and remodels arterioles,which may rely on its regulatory role on VSMC switching from proliferative to contractile phenotype,and miR-145 is involved in this process.However,the Akt activation is not caused by the overexpression of miR-145,but through other means to promote the above VSMC switching.
