Objective To observe the effectiveness of alprostedil in treatment of diabetic nephropathy and the mechanism of the renal protection of the drug. Methods One hundred patients with diabetic nephropathy due to diabetes mellitus were randomly divided into 2 groups ,50 in treatment group ,and 50 as controls, alprostadil was used intravenously in the Treatment Group for 12 day while routine management of diabetes such as food intake control,physical exercises and oral drugs or injection of insulin was conducted in both of the 2 groups. Urinary albumin were employed for evaluation as well as the side-effects. Results By the end of the trial, urinary albumin was decreased significantly compared with those before intravenous alprostadil treatment or with those in the control group (P<0.05). Conclusion Urinary albumin was decreased significantly after intravenous alprostadil. Therefore,it is a safe and effective drug in the treatment of diabetic nephropathy.

Objective To clarify the risk,treatment and preventive measurement of transfusion related acute lung injury (TRALI) occurred in HLA half-matched hematopoietic stem cell transplantation. Methods A case of TRALI occurred in HLA half-matched hematopoietic stem cell transplantation was analyzed,including the clinical characteristics,the laboratory and instrumental examination,the treatment measure and prognosis,and then the associated literature was reviewed.Results Owing to the blood products(fresh platelet) transfusion during transplantation,the patient got TRALI. And after active rescue,the patient eventually died due to the worsen condition.Conclusion The risk of TRALI is very high in HLA half-matched hematopoietic stem cell transplantation since the blood products transfusion is inevitable,so the effective and timely treatment and preventive measurement are necessary.

Objective To investigate the causes of a suspected outbreak of lower respiratory tract infection (LR-TI)caused by carbapenem-resistant Acinetobacter baumannii (CRAB)in the general intensive care unit(ICU)of a hospital,and provide scientific evidence for effective control of healthcare-associated infection(HAI).Methods Epi-demiological investigation on patients infected with CRAB and on-site monitoring on ICU environmental hygiene from March 4 to 23,2014 were performed,active prevention and control measures were taken.Results A total of 7 patients developed CRAB infection,the total length of stay during epidemic period were 160 days,the infection density of LRTI was 43.75‰(7/160),4 of 5 patients at No.02 bed had CRAB LRTI.Univariate analysis revealed that adopting conventional sputum suction procedure was a risk factor;the qualified rate of bacterial count on the object surfaces was 31 .75% (20/63).CRAB was also isolated from outer frame of suction device of No.02 bed, which had the same antimicrobial pattern as CRAB from 7 patients’sputum.After taking a series of controlling measures,there was no CRAB infection case after March 24,2014,this outbreak was effectively controlled. Conclusion This suspected HAI outbreak may be caused by inadequate disinfection of outer frame of suction device contaminated by CRAB,and horizontally transmitted through manipulation of sputum suction by health care workers.Clean and disinfection of ICU environmental object surfaces is of great importance for preventing HAI.

Objective To evaluate the effects of pegylated interferon plus ribavirin on naive and retreated chronic hepatitis C (CHC) patients.Methods A total of 67 CHC patients were divided into naive group (n =35) and retreat group (n =32) based on their treatment history.And their virological responses [rapid virological response (RVR),early virological response (EVR),virological response to etravirine (ETR) and sustained virological response (SVR)] and risk factors were analyzed.Results ①RVR and EVR of naive group were 60％ (n =21) and 77％ (n =27),respectively,and the retreat group were 28％ (n =9),53％ (n =17).The differences between the two groups were significant (both P ＜ 0.05).On the contrary,CHC patients in both groups might achieve similar ETR and SVR rates (P ＞ 0.05) ; ② The relapse rate in the retreat group was higher than that in the naive group (22％ vs.10％).But the differences had no statistical significance (P ＞ 0.05) ; ③ CHC patients in the retreat group could achieve similar responses,including RVR,EVR,ETR and SVR (P ＞ 0.05) whether treated previously with standard interferon or pegylated interferon; ④ According to muhivariable logistic regression analysis,the retreated genotype 1 CHC patients has a lower SVR rate compared with naive genotype non-1 counterparts (OR =0.29 and 0.26,all P ＜ 0.05).Conclusions CHC patients in the naive group could achieve higher virological responses and a lower relapse rate compared to those in the retreat group.The previous treatment regimeu has no significant effect on virological responses of CHC patients retreated with Peg-IFN plus ribavirin.Genotype 1 and retreatment are both risk factors of achieving SVR.

Objective To explore the risk factors of surgical site infection(SSI)in patients undergoing selective brain tumor resection,and provide reference for clinical prevention and treatment.Methods Patients who under-went selective brain tumor resection in the neurosurgery department of a hospital during April-September 2013 and April-September 2014 were monitored prospectively,monitoring programme and individualized questionnaire were formulated,the basic data,operation condition,postoperative symptoms/signs,laboratory test results,infection-related factors,and antimicrobial use in patients were collected,risk factors for infection were analyzed.Results A total of 205 patients were investigated,23 (11 .22%)of whom had SSI;univariate analysis showed that body mass index (BMI),NNIS score,and cerebrospinal fluid leakage were related to the occurrence of SSI(all P<0.05);lo-gistic regression analysis showed that high NNIS score and cerebrospinal fluid leakage were independent risk factors for SSI in patients undergoing selective brain tumor resection(both P<0.05).Conclusion Incidence of SSI is high-er in patients with selective brain tumor resection,corresponding preventive measures should be taken according to different risk factors including cerebrospinal fluid leakage.

Objective To observe the protective effect of Xiaohuangdecotion against liver damage inα-naphthylisothiocyanate (ANIT)- induced cholestasis in rats and probe the potential mechanisms.Methods Male Wistar rats (40) were randomly divided into a normal group, a model group, aXiaohuangdecotion treatment group, and a UDCA control group (10 for each). Except for rats in the normal group, ANIT solution (6 ml/kg) was administered in other rats by gavages for cholestasis model. After ANIT treated 48 h, rats inXiaohuangdecotion group and UDCA group were treated withXiaohuangdecotion (1.73 g/kg) and UDCA (10 mg/kg) respectively for 1 week. And, rats in the normal group and the model group were given an equal volume of saline. At the end of the experiment, liver function rats were examined. Liver histology was examined by HE staining, and CD68 factor was tested by immunohistochemistry and Western blot.Results Compared with the model group, the content of ALT (164.6 ± 53.4 U/Lvs. 208.4 ± 28.5 U/L), AST (247.6 ± 76.1 U/Lvs. 341.8 ± 32.8 U/L), ALP (601.0 ± 101.1 U/Lvs. 720.6 ± 123.3 U/L), TBiL (96.5 ± 18.1μmol/Lvs. 149.6 ± 30.2μmol/L), DBiL (73.7 ± 16.6μmol/Lvs. 140.3 ± 28.6μmol/L) and TBA (93.4 ± 13.0μmol/Lvs. 146.5 ± 38.9μmol/L) were significantly reduced in the treatment group (P<0.01 orP<0.05). Compared with the model group, CD68 level (7.08 ± 0.19 vs. 17.42 ± 0.48)were significantly reduced by intervention ofXiaohuangdecotion (P<0.01).ConclusionsXiaohuangdecotion could improve liver functions and reduce CD68 expression, leading to a good hepatoprotective and jaundice-relieving effects.

Objective To evaluate the relationship between long non-coding RNAs (LncRNA) in tumor tissues and clinico-pathological features of hepatocllular carcinoma (HCC).Methods Using hepatocellular carcinoma gene database GSE36376,we conducted a study on eight LncRNAs which are associated with liver diseases and analyzed the correlation between these LncRNAs and HCC clinico-pathological characteristics.We also evaluated the potential effect of LncRNAs on HCC development.Results H19 was overexpressed in non-tumorous tissues of HCC (P ＜ 0.05),while MEG3,HOXA13,KCNQ1OT1 were all upregulated in tumorous tissues (all P ＜ 0.05).HULC level in HCC tumorous tissues was negatively correlated with AJCC staging,BCLC staging and tumor size (all P ＜ 0.05).UCA1 was positively correlated with BCLC staging (r =0.135,P ＜ 0.05).Univariate analysis and multivariate logistic analyses showed that UCA1 was a risk factor of intrahepatic metastasis of HCC (OR =6.054,95％ CI =1.429 ～ 25.642,P ＜ 0.05); in contrast,HULC overexpression in tumorous tissues played a positive role in HCC tumor size (OR=0.805,95％CI=0.678 ～0.956,P＜0.05).Conclusion HULC in tumorous tissues suppressed HCC proliferation,while UCA1 was a risk factor of HCC aggressiveness.

Objective To analyse distribution of age and gender characteristics of specific IgG(sIgG)antibodies and specific IgE (sIgE)antibodies of 13 types of food allergens in patients with food anaphylaxis,and to explore the relationship between sIgG and sIgE in food anaphylaxis.Methods 314 cases of patients from 2009 to 2012 were selected as subjects,and divided into underage group(1 63 cases)and adult group(1 5 1 cases).Serum sIgG of 13 types of food allergens were detected by using enzyme linked immu-nosorbent assay,serum sIgE of these food allergens were detected by using immune capture.Results 80.25% of the patients were sIgG-positive,and no obvious gender differences were found;while the positive rates of sIgG in the underage group(94.48%)were higher than that in the adult group(64.90%),there were statistically significant differences(P < 0.05 ).34.39% of the patients were sIgE-positive.The positive rates of sIgE in male patients(40.68%)were higher than that in female patients(26.28%),and that in the underage group(55.21%)were also higher than that in the adults group(1 1.92%),there were statistically significant differences(P <0.05).Conclusion The total positive rates and its distribution characteristics of sIgG and sIgE of same food aller-gens were obviously different.Food anaphylaxis might be associated with age,gender,food types and individual diversity.

Objective:To evaluate the quantity and function changes of dendritic cells ( DC) in peripheral blood of patients with repeated implantation failure ( RIF).Methods:30 patients with RIF and 15 normal controls were enrolled in this study,and the peripheral blood was collected during the mid-luteal phase.The percentage of DC subsets and the expression levels of functional molecules were assessed by flow cytometric analysis.Results:Compared with normal controls,the percentage of lin-HLA-DR+DC cells accounting for leukocytes in patients with RIF was not significantly different ( P>0.05).There were also no significant differences in the expression levels of co-stimulatory molecules ( CD80 and CD86) and immune tolerant molecules CD200 on DC cells surfaces between patients with RIF and normal controls ( all P>0.05).In addition,the percentage of CD11c+CD123-mDC accounting for DC cells was significantly increased in patients with RIF (P<0.05),however,the percentage of CD11c-CD123+pDC was similar (P>0.05). Conclusion:The percentage of mDC accounting for DC cells was significantly increased in patients with RIF, which may be one of factors affecting pregnancy outcomes.
