This research based on the analysis of spontaneous reporting system (SRS) data which the 9 601 case reports of Shuxuening injection adverse drug reactions (ADR) in national adverse drug reaction monitoring center during 2005-2012. Apply to the association rules to analysis of the relationship between Shuxuening injection's ADR and the characteristics of ADR reports were. We found that ADR commonly combination were "nausea + breath + chills + vomiting", "nausea + chills + vomiting + palpitations", and their confidence level were 100%. The ADR and the case reports information commonly combination were "itching, and glucose and sodium chloride Injection, and generally ADR report, and normal dosage", "palpitation, and glucose and sodium chloride injection, and normal dosage, and new report", "chills, and generally ADR report, and normal dosage, and 0.9% sodium chloride injection", and their confidence level were 100% too. The results showed that patients using Shuxuening injection occurred most of ADRs were systemic damage, skin and its accessories damage, digestive system damage, etc. And most of cases were generally and new reports, and patients with normal dosage. The ADR's occurred had little related with solvent. It is showed that the Shuxuening injection occurred of ADR mainly related to drug composition. So Shuxuening injection used in clinical need to closely observation, and focus on the ADR reaction, and to do a good job of drug risk management.

Results Lean muscle mass of whole body increased with the copy of the G allele of TNFRSF11B-rs2875845 and the T allele of TNFRSF11B-rs1485288 (P<0.05). Conclusion The G allele of rs2875845 and the T allele of rs1485288 in TNFRSF11B gene increase the level of the lean muscle mass in Chinese Han population.

Objective To investigate the effect on bioeffects such as sonoporation and cell killing that induced by domestic ultrasound contrast agent(perfluoropropane-albumin microsphere)and diagnostic ultrasound by microbubble concentration.Methods Suspensions of hepatocyte with microbubbules in different concentrations were exposed to diagnostic ultrasound.The study included blank contrast group(no microbubble,no ultrasound),exposed group(no microbubble,exposed to ultrasound)and 6 microbubble groups in different concentration(with different microbubbule/cell ratios for 1,5,10,50,100 and 200,exposed to ultrasound for 10min).The uptake of fluorescein isothiocyanatedextran(FD500)by hepatocyte was observed and the percentages of sonoporation cells were counted,the cell viability was determined by trypan blue stain immediately after exposure,and apoptosis of ceils were detected by flow cytometry,with double staining of fluorescein isothiocyanate(FITC)-labeled Annexin V/propidium iodide(PI).Results Fluorescence stain results:compared with blank contrast group or exposed group,the sonoporatin of groups with microbubble/cell ratio of 5 to 200 increased significantly(P＜0.05).Cell killing effects:compared with the blank contrast group,only the cell death percentages of microbubble groups with microbubble/cell ratio of 50,100 and 200 increased significantly(P＜0.05).Compared with the exposed group,only that of groups with microbubble/cell ratio of 100 and 200 increased significantly(P＜0.05).There was no significant different between blank contrast group and exposed group for all these results.Conclusions Sonoporation and cell killing effect can be induced by diagnostic ultrasound in HL-7702 with domestic ultrasound contrast agent(perfluoropropane-albumin microsphere).For diagnosis,the ratio of microbubbule/cell should better be under 10.While for gene transfection,the ratio should better be 50 and could be 100 if it is necessary.

OBJECTIVETo discuss the changes in Wnt pathway inhibiting factors in esophageal precancerosis lesions induced by methyl benzyl nitrosamine (MBNA) and the effect of Gexia Zhuyu decoction.

METHODWistar rats were subcutaneously injected with MBNA (3.5 mg x kg(-1) for twice per week to establish the model. Since the 1st day after the model establishment, they were orally administered with Gexia Zhuyu decoction (16, 8 mg x kg(-1)). At the 10th week, esophageal tissues were collected to observe the pathological changes of esophageal mucosa, detect SFRP1, sFRP4, Axin1, Axin2 and GSK-3β mRNA levels.by fluorescent quantitation PCR analysis and β-catenin protein level by Western blotting.

RESULTBeing induced by MBNA, rats in the model group showed slight atypical hyperplasia in the histopathological examination. Compared with the normal group, Gexia Zhuyu decoction dose high and low groups showed no significant pathomorphological and histological changes. The model group showed lower gene transcription levels of esophageal tissues sFRP1, sFRP4, Axin1 and Axin2 (P < 0.05 or P < 0.01) and higher β-catenin protein expression level (P < 0.01) than the normal control group. The Gexia Zhuyu decoction low dose group showed higher gene transcription levels of esophageal tissues sFRP1, sFRP4, Axin1 and Axin2 (P < 0.05 or P < 0.01) and lower β-catenin protein expression level (P < 0.01) than the normal control group.

CONCLUSIONUp-regulated β-catenin protein level and down-regulated Wnt pathway could enhance Wnt pathway activity of MBNA-induced esophageal precancerous lesions. Gexia Zhuyu decoction could down-regulate the β-catenin protein level and up-regulate the transcription level of Wnt pathway inhibiting factors, but could not block MBNA-induced esophageal precancerosis lesions.

Objective To analyze epidemiological and clinical characteristics of chronic hepatitis C (CHC) patients. Methods The clinical data of 323 CHC patients were collected. The transmission modes, clinical manifestations and virological features were recorded. The liver histological change was also analyzed in 39 cases whose liver biopsy samples were available. The comparison between two groups was performed by t test. Results Among the 323 CHC patients, 135 cases (41. 8%) had history of blood or blood products transfusion. Sixty-seven cases (20. 7%) had undergone surgery and trauma operation. Nineteen cases (5. 9%) had history of Chinese medicine acupuncture. Eighteen cases (5.6%) had undergone hemodialysis. Two patients (0.6%) were infected through vertical transmission. Twenty-one cases (6. 5%) had history of intravenous drug use and two cases (0. 6%) had history of unsafe sexual contact. The possible transmission routes for the other 78 cases (24.1%)were unknown. Fourteen patients (4. 3%) were co-infected with hepatitis B virus (HBV). The major prevalent genotypes were hepatitis C virus ( HCV) genotype lb and 2a, which were 145 cases (65. 3%) and 21 cases (9. 5%) respectively. HCV viral loads were as high as 1 × 105 IU/mL in 74 cases (26. 1%) and 1× 106 IU/mL in 103 cases (36. 4%). Twenty-three patients (7.1%) developed obvious clinical manifestations. Among 39 patients undergoing liver biopsy, 14 cases (35. 9%) had hepatic inflammation activity index (HAI)≥4, six cases (15. 4%) had fibrosis stage (F) ≥3, four cases (10. 3%) had HAI≥4 and F≥3. Conclusions The most common HCV transmission modes are blood transfusion and use of blood products. However, surgery and trauma operation should be paid more attention. Besides blood transfusion, the transmission modes of intravenous drug injection, hemodialysis and traditional Chinese medicine acupuncture are increasing. The major HCV genotypes are lb and 2a. The viral loads of most patients are relatively high. Most patients infected with HCV don't show any obvious hepatitis symptoms and physical signs. However, the liver biopsy results from 39 patients suggest that most patients develop liver histological changes.

Objective To evaluate the value of the real-time tissue elasticity imaging quantitative method in differential diagnosis of thyroid nodules.MethodsSeventy-three patients with thyroid nodules，including 95 lesions,were included in the study.A total of thyroid nodules were examined with traditional ultrasonography and elastosonography from which the strain ratios(SR)were derived，with pathologic results as the reference standard.And a receiver-operating charaeterisitc(ROC)curve was used to identify the value of optimal operating point for differential diagnosis of thyroid nodules.Results①The strain ratio of the benign lesions was 2.06 ±1.01，which was significantly different from the value of malignant lesions 5.05±2.23(P＜0.05).②The area under the curve was 0.929，which showed a high statistical significance.③It showed that the optimal operating point of ROC curve was 3.17，with high sensitivity(96.7%)，specificity(90.8%)，postive predictive value (93.3%)and negative predictive value(96.9%).Conclusions The real-time tissue elasticity imaging can provide a quantitative,noninvasive and convenient tool for evaluating the thyroid nodules.
