OBJECTIVE:To provide references for the accountability of civil liability induced by different causes.METHODS:Literature retrieval and case study were applied to analyze the civil liability of pharmaceutical manufacturers and medical institution in medication misadventures.RESULTS & CONCLUSIONS:At present it is difficult for patients who suffered from medication misadventures caused by drug quality defects,drug adverse reaction or medication errors to claim.The main reasons are imperfect relevant law system and the vacancy of compensation mechanism of drug-induced injury events.It is suggested to establish technology institution for evaluating medication misadventures,state relief and compensation system and encourage pharmaceutical manufacturers to buy products liability insurance.

The study investigated the effects of red clover extract (RCE) on mouse T macrophages and lymphocytes in vitro. The cell toxic effect of RCE was estimated by MTT assay. Multiple-fluorescence staining plus flow cytometry were used to detect the effect of RCE on CD69/CD25/CD71 expression of mouse T lymphocytes stimulated by Con A; CFDA-SE staining plus flow cytometry were used to analyze the effect of RCE on proliferation of T lymphocytes activated by Con A; The effect of RCE on nitric oxide(NO) secretion of mouse macrophages stimulated by lipopelysaccharide (LPS) for 24 h was assayed by Griess reagent system. We found that RCE had potent anti-inflammatory effects on mice. RCE had littl ecell toxic effect on mouse lymphocytes and macrophages. RCE strongly inhibited the excessive production of inflammatory mediators ( NO, CD69, CD25, CD71 ), in a dose-dependent manner, like cyclosporine A injection. RCE could inhibit proliferation of CD3<'+> T lymphocytes. These data suggested that RCE migh texhibit anti-inflammatory effect by inhibiting the activation and proliferation of mouse lymphocytes and the NO secretion of mouse macrophages.

Objective: To observe the effect of Trifoliumpratense Leguminosae extract (TLE) on mouse allogenetic skin transplantation. Methods: Recipient BALB/c was divided into physiologic saline (PS) group and TLE group, full-thickness skins were transplanted through back to back method from donor C57BL/6. The allogenetic transplanted skin growth condition was observed. The proliferation of lymphocytes of recipient mice in vitro were detected by CFDA-SE stain and mixed lymphocyte reaction respectively. Results: The allogenetic transplanted skin injected with TLE 25g/kg per day by vena caudalis growed better than that in PS group. The proliferation of lymphocyte in TLE group was smaller than that in PS group. Conclusion: TLE maybe participate in the regulation of mouse immune system and induce its tolerance to the allogenetic transplanted skin.

Objective To evaluate the application of the binary Logistic regression model to analyze ultrasonographie indexes of the solid breast tumors. Methods The indexes of two dimensional gray scale ultrasonography,two dimensional color Doppler flow imaging,three dimensional gray scale ultrasonography, three dimensional color Doppler flow imaging and ultrasonic elastography were evaluated in 151 breast lesions confirmed by surgical pathology. A Logistic regression model for predicting breast rnalignaney on the basis of ultrasonographic indexes was obtained. A receiver operating characteristic (ROC) curve was used to assess the performance of the Logistic regression model. Results Six ultrasonic indexes were finally entering the Logistic regression model. They were elasticity score, shape,internal echo, RI, enhancement of posterior acoustic alteration and the converging pattern in the coronal plane. The area under the ROC curve was 0. 996. The percentage correct of prediction was 97.35 %. Conclusions The multivariate analysis model of binary Logistic regression can describe and analyze the process of differential diagnosis of malignant and benign solid breast tumors by ultrasonography and can select out the valuable indexes of differential diagnosis.
