Hepatitis C virus (HCV) is a blood-borne virus transmitted through contact with blood and blood products,and it is a major cause of liver cirrhosis and hepatocellular carcinoma.Many epidemiological studies have confirmed the association between HCV infection and renal disease.Membranoproliferative glomerulonephritis associated with mixed cryoglobulinemia is the most common type of HCV-related renal disease manifesting as nephropathy or nephritic syndrome,proteinuria,hematuria,and reduced glomerular filtration rate.The treatment of HCV-related renal disease includes antiviral therapy,B cell clearance,and non-specific immunosuppressive therapy.At the same time,the launch of rnew antiviral drugs has brought hope to the patients who cannot tolerate conventional regimens.This article reviews the research advances in epidemiology,clinical manifestations,pathogenesis,and treatment of HCV-related renal injury.

BACKGROUND: Reports regarding adipose-derived stern cells (ADSCs) differentiation into dopaminergic (DN) neurons are few in addition, there is not experimental evidence of the effect of ADSCs on maintaining the survival of DN neurons.OBJECTIVE: To investigate the effect of glial cell-derived neurokophic factor (GDNF)-modified adipose-derived stem cells on survival of DN neurons under co-cultured condition.DESIGN, TIME AND SETrlNG: The in vitro cytology experiment was conducted at the Institute of Otolaryngology-Head and Neck Surgery and Key Laboratory of Zoonoses of Ministry of Education between March and December 2007.MATERIALS: Wistar rats with 3-weeks-old, or 14 days of pregnancy were provided by Norman Bethune College of Medicine, Jilin University.METHODS: The GDNF recombinant adenovirus was constructed by using pAdTrackCMV and pAdEasy-1 system. DN neurons were obtained from the rostral mesencaphalic tegmentum of Wistar rat embryos by using trypsin and collagenase method. ADSCs isolated from rat inguinal fat pads were digested with collagenase Ⅱ, cultured and passaged in vitro. When the cells reached 60% cenfluency at the 3rd passage, cells were transfectad with 1×109vp/mL of Ad-GDNF for 1 hour and then transferred into growth medium for another 24 hours, and GDNF level in cell supematant was detected by ELISA assay. Meanwhile, the co-cultured of ADSCs and DN neurons were carried out for following 7 days. With GFP-modified ADSCs was served as a control group.MAIN OUTCOME MEASURES: The effect of co-cultured condition on the survival of DN neurons, as well as the differentiation of GDNF-modified ADSCs was detected by immunofluorescence staining.RESULTS: GDNF appeared in ADSCs supematant at 24 hours after Ad-GDNF transfection and reached a peak at 72 hours.There was approximately 80% GFP-positive labeled in ADSCs. The tyrosinase hydroxylase staining results demonstrated that the rate of survival DN neurons were significantly increased than in DA neurons cultured alone, co-cultured group of GFP-modified ADSCs and GDNF-modified ADSCs groups (55%, 15%, 25%, P < 0.01). However, there were no co-expressing TH and GFP positive cells appeared at 7 days of co-culture, which indicated that the co-cultured condition was not available to ADSCs differentiation.CONCLUSION: The co-cultured of GDNF modified ADSCs and DN neurons can promote the survival and growth of cultured DN neurons, however, it can not induce ADSCs differentiate into DN neurons.

Objective To investigate the functional ankle instability in nurses,and provide references for increase preventive and protective awareness and establishment of preventive measures.Methods 100 nurses recruited from 10 wards of Provincial Hospital Affiliated to Shandong University were included into this study.Chinese version of the Cumberland Ankle Instability Tool (CAIT) was used to investigate the condition of functional ankle instability of these nurses.A self-designed questionnaire was used to investigate cognitive degree of ankle sprain prevention and treatment knowledge.Results Only 16％ of these nurses had no unstable problems in both of their two ankles.There were functional ankle instable problems in either single or both of the two ankles of the other 84％ nurses.And most of the nurses had little knowledge of how to prevent or treat ankle sprain properly.Conclusions There is a high rote of functional ankle instability in nurses.It is necessary to pay great attention to the prevention of ankle sprain and instability in nurses,which is of great importance to health and occupational safety assurance of nurses.

Objective To investigate the clinical significance of c-myc、Bcl-2 protein expression, DNA ploidy and their relationship in breast cancer. MethodsWT5”BZ The expression of c-myc、Bcl-2 protein in 146 breast tumor tissues was examined by using immunohistochemical methods(S-P)and DNA ploidy in 72 cases of breast carcinoma by flow cytometry. ResultsKG1 Nuclear expression of c-myc protein was detected in 9 6% of tumors, and it was related to the DNA aneuploidy and prognosis. Cytoplasmic expression of c-myc protein was present in 91 8% of the carcinomas. Moderate to strong c-myc protein expression in cytoplasmic was associated with the positive status of ER. Bcl-2 protein was positive in 78 8% of cancers. Overexpression of Bcl-2 protein was associated with ER(+) status and the lack of axillary lymph node metastasis. DNA aneuploidy was found in 51 4% of 72 cancers, it was related to nuclear expression of c-myc protein and prognosis.WT5”HZConclusion Nuclear expression of c-myc protein and DNA ploidy are important prognostic factors.

The frequency of MTH?FR A1298C genotype and allele frequencies in Xiangtan is 4.8%which is lower than Qionghai(7.1%)but higher than Zibo (1.4%),Zhengzhou(2.4%), Yantai(1.8%), Zhenjiang(3.5%)and Songzi(2.6%)with statistically significant difference. The frenquency of MTRR A66G genotype and allele frequencies in Xiangtan is 6.8%which is higher than Zibo (4.8%) but lower than Qionghai (9.3%) with statistically signifcant difference. Plasma Hcy concentration correlate with MTHFR C677T, Hcy concentration in TT population is higher than that in CT and CC population(μmol/L:8.52±2.01 vs 5.94±1.47 vs 5.71± 0.18);Plasma Hcy concentration also correlate with MTHFR A1298C and Hcy concentration in CC population is higher than AA and AC population(μmol/L:9.83 ± 2.26 vs 6.35 ± 2.13 vs 5.55 ± 1.75);Plasma Hcy concentration does not correlate with MTRR A66G. Conclusion The gene polymorphism of MTHFR C677T, A1298C and MTRR A66G among the Han women in Xiangtan was statistically different from other selected regions of China. Mutation in MTHFR C 677T and A1298C were associated with elevated plasma levels of Hcy.

Objective To study effects of Rupixiao granules on contraction of uterus of mice in vitro. Methods Mouse model with isolated uterine contraction was established. The mice pretreated with estradiol benzoate were sacrificed and then the uteri were taken out. The normal contractions were recorded by the biological function system. Effects of 10, 20, 30, 40, 50, 60 mg.mL-1 Rupixiao granules on spontaneous and oxytocin-induced (5 U.L-1) uterine contractions were recorded,inhibition of Rupixiao granules on mean constriction amplitude,constriction frequency and contraction activity of pitocin-pretreated uterus was observed and the inhibition rates were calculated. Results Compared with the baselines, the amplitude, frequency, activity of spontaneous uterine contraction were significantly down-regulated by Rupixiao solution at a range of 10-60 mg.mL-1 ,as well as it could inhibit oxytocin-induced spasmodic contraction of isolated uterus at 10-50 mg . mL-1 ( P<0. 01 ) . Conclusion The Rupixiao granules inhibits spontaneous contraction of isolated mouse uteri and oxytocin-induced spasm of uterine smooth muscle in vitro.

Objective To evaluate the effectiveness of professional nurses in atrial fibrillation (AF) anticoagulation management system.Methods 217 consecutive patients with nonvalvular AF were enrolled.All patients received warfarin therapy for 3-6 months after catheter ablation for AF,who were divided into experimental group (n=102) and control group (n=115) by random digits table.The patients of control group adjusted their warfarin doses by following doctor's advice when discharged and by visiting the outpatient clinic regularly after discharged.The patients of treatment group adjusted their warfarin doses under the guidance of one well-trained nurse.Days of the international normalized ratio (INR) value achieved therapeutic anticoagulation range (2.0-3.0) for the first time,the effective anticoagulation rate that defined as more than 70％ of INR values between 2.0-3.0 after titration period,the ratio of times of INR value 2.0-3.0 to total times after titrating and INR monitoring frequency were compared between the 2 groups.Results In treatment group,days of the INR value achieved therapeutic 2.0-3.0 for the first time were less than that in control group (8 d vs.15 d,P＜0.01),the effective anticoagulation rate [45.1％(46/102)] and the ratio of times of INR value 2.0-3.0 to total times after titrating (67.6％±18.5％) was significantly higher than that in control group [31.3％(36/115) and 62.0％±23.1％ respectively,P＜0.05].INR monitoring during the whole period and after titrating were more frequently in treatment group [(9.4±2.2)times vs.(8.4±2.7) times,P＜0.05;(7.9±2.4) times vs.(6.3±2.8) times,P＜0.01].The number of patients in treatment group who monitor INR less than 3 times after titrating was larger than that in control group (18 vs.1,P＜0.01).Conclusions The participation of professional nurses in atrial fibrillation anticoagulation management system was helpful not only in achieving INR 2.0-3.0 more quickly but also in improving the effective anticoagulation rate.

Objective:To investigate the anti-inflammatory and analgesic effects of Rupixiao granules. Methods:Activity of Rupixi-ao granules against xylene-induced ear edema in mice was measured to evaluate the anti-inflammatory effect, while the analgesic effect was evaluated by acetic acid induced writhing test and hot plate test in mice. Results:Compared with the control group, Rupixiao gran-ules groups (1. 0, 2. 0 and 4. 0 g·kg·d-1) could significantly inhibit ear swelling in mice(P<0. 05 or 0. 001), and reduce the acetic acid induced writhing times(P<0. 01 or 0. 001). Rupixiao granules at medium and high dose could significantly increase the pain thresh-old of mice in the hot plate test. Conclusion:Rupixiao granules exhibit significant anti-inflammatory and analgesic activities.

PURPOSE: The purpose of this study was to develop and preliminarily evaluate the reliability and validity of the Symptom-Management Self-Efficacy ScaleeBreast Cancer (SMSES-BC) related to chemotherapy. METHODS: The study included three stages. This paper presents the results of stage 2 and stage 3. In total, 34 items in the SMSES-BC were found during stage 1 from qualitative findings, a literature review, and expert suggestions; the 34 items were used for the psychometric properties test. Test-retest reliability and Cronbach alpha were assessed in the first sample, which included 45 participants for the pilot test (stage 2). The second sample, which included 152 patients, was used to assess the construct validity and concurrent validity (stage 3). RESULTS: The pilot test results revealed a test-retest reliability of .73 (p < .001) and Cronbach alpha coefficient of .96 for the total scale. Three factors (managing chemotherapy-related symptoms, acquiring problem solving, and managing emotional and interpersonal disturbances) were identified from exploratory factor analysis. Correlation coefficient r was .40 (p < .001), which supported the association between SMSES-BC and the General Self-Efficacy Scale for concurrent validity. CONCLUSIONS: The study results demonstrate acceptable reliability and validity for the SMSES-BC that was developed for measuring symptom-management self-efficacy related to chemotherapy for patients with breast cancer. This study suggests further research to validate the construct of the SMSES-BC.
