As the increasing of digital imagilag modalities,a close-at-hand challenge to deal with is the storage and transmission requirement of enormous data of medical images.Compression is one of the indispensable techniques to solve this problem.A comprehensive review and discussions are made in this paper over the medial image compression techniques applied in medical image domain,including the latest achievements in this field.Different compression algorithm including ROI-based coding,lossless compression,DWT,neural net are introduced and some quality evaluation methods are introduced.Foreground of the field is given from our point of view.

There has been great progress in seizure control with the development of antiepileptic drugs,but 30％ of epileptic children are refractory to antiepileptic drugs.In order to control intractable epilepsy and improve neurodevelopment prognosis,the non-drug therapy such as surgery,vagus nerve stimulation and ketogenic diet (KD) can be taken.Despite its indisputable effectiveness,the functioning of the KD has not been explained.Now the antiepileptic mechanism and neuroprotective mechanisms are studied mainly.It is reported that KD is effective in variety of refractory epilepsy,and recent studies have shown that KD promising in the treatment of children with autism.Although KD is effective,it is worth further study that including its mechanism,recipe,clinical application,and so on.

Drug-induced lupus (DIL) is a lupus-like illness that has been recognized as a side effect of over 80 drugs since its first description in association with sulfadiazine in 1945. The epidemiology and clinical course of idiopathic systemic lupus erythematosus and DIL differ markedly, and prognosis is generally favorable in the latter although occasional life-threatening cases have been reported in the literature. Constant pharmacovigilance is crucial for prompt diagnosis and cessation of offending therapy, hence achieving the best outcome. This review discusses the clinical presentation, diagnosis and treatment of DIL so as to call for vigilance of medical workers.

A simple, rapid and accurate method is described for the determination of icariin in Fuchun Tablets by reversed-phase high-efficiency liquid chromatography. The samples were first extracted with 70% alcohol for 50 minutes The resulting solutions were chromatographed on aYWG-C18 column.By using a mobile phase of methanoltetrahydrofuran-water (26.5:15.9:56.7) and a detection wavelength at 274 nm, the recovery for 101.02%, CV=2.4%,are obtained.The method can be employed for the quality control of Fuchun Tablets.

Objective:To make a prospective study on the effectiveness and safety of toremifene (TOR) combined with novelbine/cisplatin (NP) in the treatment of patients with advanced non-small cell lung cancer (NSCLC) whose first line platinum-based chemotherapy was failure. Methods:Forty-four patients with stage ⅡB-Ⅳ NSCLC, who failed in the first line cisplatin-based chemotherapy from January 2004 to February 2006, were enrolled in this study. All the patients received TOR combined with NP second line chemotherapy for two cycles. The response rate and adverse reaction were evaluated. The survival rate was analyzed.Results:The 44 patients received average 1.8 cycles of chemotherapy (1-3 cycles). The response of 37 patients could be evaluated including 21 patients who received NP regimen before and 16 patients who received platinum-based chemotherapy. After second line therapy, 4 of the 37 patients had partial response (PR), 19 had stable disease (SD), 14 had progressive disease (PD), and no patient had complete response (CR). The total response rate (CR+PR) was 10.8% (4/37). The disease-controlling rate (CR+PR+SD) was 62.2% (23/37). The response rate and disease-controlling rate of squamous cell lung cancer (SCC) were 27.3% (3/12) and 72.7% (8/12), which were significantly higher than adenocarcinoma [0% (0/18) and 44.4% (8/18), P<0.05]. The median survival time was 8.2 months, the median time for SD was 4.0 months (1.0-10.2 months), and the 1-year survival rate was 24.4%. The median survival time and 1-year survival rate of SCC patients had no significant difference compared with adenocarcinoma patients (9.2 vs 7.1 months; 33.3% vs 27.7%, P＝0.72). There was no significant difference in survival rate between male and female patients. One patient stopped therapy for liver function injury (hyperbilirubinemia). The adverse reactions induced by chemotherapy mainly included gastrointestinal reaction, bone marrow suppression, and liver function injury. No serious adverse reaction occurred. Conclusion:The clinical efficacy of second line TOR combined with NP regimen is similar with the first line regimen for NSCLC patients, especially for SCC patients. The frequency of adverse reaction is not increased.

Objective To study the inhibitory effects of stachyose on the hyperacute rejection in pig-to-human heart xenotransplantation.Methods A pig-to-human xenogeneic heart transplantation model was established based on an in vitro free heart blood perfusion system.The pig hearts were di- vided into two groups:group A(pig hearts treated with human blood perfusion as control)and group B(pig hearts treated with human blood plus stachyose perfusion).After perfusion for 1h,the heart xenografts were examined for deposit of lgG and IgM by immunohistochemistry and pathological analy sis.Results The mean survival time of perfusion hearts in groups A and B was(9.5?2.5)min and (46.8?8.1)min respectively(P
