Purpose:To evaluate the efficacy of NP regimen (NVB and DDP) in advanced non-small-cell lung cancer (NSCLC). Methods:48 patients with advanced NSCLC were treated by NP regimen. All of them had stage Ⅲ-Ⅳ disease (22 of them were primary treatment, the others were subsequent treatment). The chemotherapy dosage of NVB was 25 mg/m2 iv. d1,5, That of DDP was 35 mg/m2 iv d1,3.Results:The overall response rate (RR) was 50%, medium response time 5.5 months, medium survival time 11 months. The RR of 22 patients with primary treatment was 63.6%. The other patients after multiple course therapy 38.5%. The major adverse effects were myelosuppression and vein inflammation drug infusion through deep vein could avoid the vein inflammation. Conclusions:Authors suggest that NP regimen is effective therapy for non-small-cell lung cancer and deserves further clinical observation.

Purpose:To investigate clinical effects and side reactions of advanced NSCLC by combined chemotherapy base on gemcitabine. Methods:36 cases of advanced NSCLC were divided into two groups: Group 1, 20 cases were treated by gemcitabine 1.6 g at d1,d8,d15 and 80mg/m 2 DDP at d1; Group 2,16 cases were treaded by gemcitabine 1.6 g and paclitaxel 60 mg at d1,d8,d15.Both groups were repeated every 4 weeks and clinical effects were evaluated after 3 cycles.Results:CR 1 case, PR 17 cases, SD 16 cases, PD 2 cases and CR+PR 18 cases (response rate 50 0%) in 36 cases observed. In 20 cases primary treatments:CR+PR 11cases (response rate 55 0%);In 16 cases re-treatments: CR+ PR 7 cases (response rate 43.75%); In 15 cases of advanced NSCLC re-treated by gemcitabine combined with paclitaxel: CR+PR 7 cases (response rate 46.7%). Side reaction: most cases showed bone marrow suppression and symptoms of gastrointestinal side-effects, which included 12 cases of Ⅲ-Ⅳ grades leukocytopenia (33.3%),7 cases of Ⅱ-Ⅲ grades soterocytopenia (19.4%),8 cases of Ⅲ-Ⅳ grades symptoms of gastrointestinal side-effects (22.2%),2 cases of Ⅱ grades abnormal liver function.Conclusions:Better clinical effects have been achieved in the therapy of advanced NSCLC by combined methods based on gemcitabine and side-reactions are tolerable;Nice effects were obtained in the re-treatment of NSCLC by gemcitabine combined with paclitaxel.It is valuable to investigate its Clinical effects more deeply.

Nuclear receptor transcription factors are ligand-activated proteins that control various biological events from cell growth and development to lipid metabolism, and energy and glucose homeostasis. Nuclear receptors are important drug targets for metabolic diseases. Liver X receptors (LXRs) are nuclear receptor transcription factors that play essential roles in regulation of cholesterol, triglyceride, fatty acid, and glucose homeostasis. LXR-deficient mice have shown the association of LXR-signaling pathway dysfunction with several human pathologies including atherosclerosis, hyperlipidemia, Alzheimer's disease and cancer. Thus, LXRs are promising pharmacological targets for these diseases. Synthetic LXR agonists may lower cholesterol, but increase triglyceride and induce fatty liver. The naturally occurring LXR ligands, with moderate activity, may serve as nutraceuticals for prevention or treatment of the disorders, while minimizing potential side effects. In this review, recent advances in natural LXR modulators are summarized including agonist, antagonist and the modulator of LXR pathway.

Chondroblastoma of the patella, rare occurred in patellar,is a kind of an uncommon benign bone tumor. Compared with giant cell tumor, the morbidity of chondroblastoma is lower. Meanwhile, its clinical manifestations are various, and images are very complicated. Therefore, the understanding of this kind of tumors may be limited even to the orthopedist. The differences of patellar chondroblastoma between other tumor in X-ray, CT and MRI is a spot in recent years. Sometimes patellar chondroblastoma coexists with aneurysmal bone cyst, which is a challenge to obtain an accurate pathological and radiological diagnosis. For the treatment, curettage and bone grafting is one the most popular method, but whether to perform a biopsy before surgery still remain controversy. Some new technique still has an unknown prospect for the treatment such as radiofrequency ablation.

Purpose To investigate the MRI findings and to improve the understanding of spinal epidural angiolipomas. Materials and Methods MRI findings were retrospectively analyzed in two cases of surgery and pathology proven spinal epidural angiolipomas. Relevant literatures were reviewed. Results Two cases of spinal epidural angiolipomas were located in the lumber and lower thoracic spinal canal. The tumors were elongated or spindle in shape within the epidural space, and parallel to the longitudinal axis. In both cases part of the tumors were hyperintense on T1WI and T2WI, attenuated on fat-saturated sequences with mild enhancement. Some areas were hypointenseon T1WI, hyperintenseon T2WI, unattenuated on fat-saturated sequences with apparent enhancement. Angiolipomas were classified according to the MRI features. One was type I and the other was type III. Both cases were non-infiltrative. Conclusion MRI shows the size, shape, MRI signals and the association with the adjacent structure of spinal epidural angiolipomas. The MRI classification is helpful for improving the understanding of the tumor. MRI is the best imaging modality to diagnose spinal epidural angiolipomas.

Mice infected with Schistosoma japonicum were treated with a single oral dose of levo-praziquantel 75mg/kg or racemic praziquantel 150mg/kg. 10min-7d after administration of the drugs, the infected mice were sacrificed and the parasites were studied. The tegumental antigen of the integral worms and of. the worm sections were tested by IFA.10-30 min after treatment more than 50% of the tegumental surface of adult worm showed weak and small fluorescent spots in treated groups. 1-6h after treatment, the sucker and extremity of adult worm showed brighter fluorescent spots. From 6h after treatment, there were very bright fluorescent spots on the whole worm surface. 3d after treatment, the fluorescent intensity was weaker than before, and there was no significant difference between the levo-praziquantel group and racemic praziquantel group in the exposure of tegumental surface antigen. The results demonstrated that levo-praziquantel, just like the racemic-praziquantel, could disturb the tegumental metabolic course of the schistosomes, caused tegumental damage and exposure of adult worm surface antigen.

Restenosis is a major complication after percutaneous transluminal coronary intervention. Evaluation of restenosis early and accurately can help to giude treatment, improve outcome and save costs for the patients. All kinds of imaging methods for restenosis have their merits and demerits. It is essential to choose the appropriate imaging method in clinical practice.

Objective: To establish a method for the determination of ketoconazole and miconazole nitrate in compound ketocon-azole gels. Methods:An HPLC method was developed. A Hypersil BDS C18 column(416 mm × 200 mm,5μm) was used, the mobile phases consisted of 0. 5% ammonium acetate solution-methanol(containing 0. 2% triethanolamine) (20∶80), the flow rate was 1. 0 ml ·min-1 , the detection wavelength was set at 230nm, the column temperature was 30℃ and the injection volume was 20μl. Results:There was a good linear correlation within the range of 5. 1-510. 0 mg·L-1 for ketoconazole (r=0. 999 9) and 50. 0-500. 0 mg·L-1 for miconazole nitrate (r=0. 999 9), the average recovery for ketoconazole and miconazole nitrate was 100. 3%(RSD=0. 38%, n=6) and 99. 9%(RSD=0. 79%, n=6), respectively. Conclusion:The method is simple, rapid, accurate and sensitive, and can pro-vide a method for controlling the quality of compound ketoconazole gels.
