Although the optimal treatment protocol for clinical N2-stage non-small cell lung cancer (NSCLC) is still uncertain, the recommended standard treatment protocol goes to radical concurrent chemora diotherapy. Concurrent chemoradiotherapy after induction chemotherapy is not superior to standard concurrent chemoradiotherapy. Neoadjuvant concurrent chemoradiotherapy followed by pulmonary lobectomy can improve overall survival ratio comparaed with preoperative neoadjuvant concurrent chemoradiotherapy. The role of concurrent chemoradiotherapy followed by consooldation chemotherapy is still controversial. Gefitinib or erlotinib failed to bring about the survival benefit from the maintenance treatment after concurrent chemoradiotherapy. Prophylactic cranial irradiation play a role merely in decreasing the risk of brain metastases, but not in the improvement of overall survival.

Objective To understand the cognitive status of urology medical staff about hematuria color.Methods The self-designed questionnaire about color cognition was adopted,and the concentration of hematuria samples were determined.The investigation was carried out in 50 health care workers about their cognition of hematuria color.Results The study found that there were differences in color perception between doctors and nurses,doctors and nurses with different titles,doctors and the standard sample,nurses and the standard sample.Conclusions There are differences in judgment and description of the urine sample color in medical personnel,they are more attempted to judge by virtue of work experience and subjective consciousness.Due to the lack of a uniform and objective standards,the medical staff can not accurately and objectively describe the development of patients' condition,thus patients' recovery was affected.Therefore,a unified objective criteria for clinical reference norms of hematuria should be developed as soon as possible to ensure that patients recover quickly and safely.

Acid-sensing ion channels (ASICs), which are activated by extracelluar H+, are H+-gated cation channels. At present, seven subunits of ASICs family have been identified. Numerous studies revealed that ASIC1a plays important roles in synaptic transmission and plasticity,spatial learning and memory, nociception, as well as cerebral ischemia under physiological and pathological conditions. This review concerns the latest research about ASIC1a to promote the understanding of its physiological and pathological functions.

AIM: To investigate the transfection efficiency of mouse liver with non-viral vector containing manganese superoxide dismutase (Mn-SOD) gene. METHODS: The eukaryotic expression vector, gWiz/Mn-SOD, encoding human manganese superoxide dismutase was constructed. The plasmids of gWiz/Mn-SOD were mixed with cationic lipids, followed by injection into mice via branch of superior mesenteric vein, to induce Mn-SOD over-expression in murine liver detected by RT-PCR, Western blotting, SOD activity and immunohistochemical staining. RESULTS: gWiz/Mn-SOD transfection resulted in the obvious expression of exogenous Mn-SOD mRNA and protein in hepatic tissues at 8 hours after injection, and elevated mitochondria SOD activity 8.4 times in transfected hepatocytes than that in non-transfected cells at 72 hours after injection. It was showed that nearly 70% of mouse hepatocytes was obviously Mn-SOD positive after transfection. CONCLUSION: High expression efficiency of Mn-SOD gene in mouse liver is achieved safely by injection of gWiz/Mn-SOD and cationic lipid mixture into branch of superior mesenteric vein. [

In recent years, great progress has been made in the pathogenesis of psoriasis, which has provided multiple new targets for the treatment of psoriasis, and ushered the treatment, especially topical treatment, of psoriasis to a new era. Some new targeted topical drugs with action mechanisms different from those of traditional drugs have been applied in clinical practice, which are mainly small -molecule inhibitors targeting cell signaling pathways or enzymes involved in the pathogenesis of psoriasis, such as the Janus kinase/signal transducer and activator of transcription(JAK/STAT) pathway, phosphodiesterase type 4 (PDE4), mitogen-activated/extracellular-signal-regulated kinase kinase (MEK), vascular endothelial growth factor receptor (VEGFR), tropomyosin receptor kinase A (TrKA), retinoic acid receptor-related orphan receptor γ (RORγ), and so on. At present, many phaseⅠ and Ⅱ clinical trials are conducted for these drugs. Some completed trials have shown that they have good effectiveness, safety and tolerance, providing more options for the topical treatment of psoriasis.

Positive and meaningful exploration was conducted by related teachers to improve the teaching quality of oral clinical pharmacology.Case based teaching method was applied in the teaching of adverse reactions and bilingual teaching was employed in the teaching of local anesthesia.Correlation and comparison of the key knowledge points were emphasized in the teaching process. Students′ interests were aroused and satisfactory results were achieved through implementing these measures.

Objective To analyze the related factors of medical order compliance in patients with chronic prostatitis. Methods 482 patients with chronic prostatitis were investigated by using the National Institutes of Health chronic prostatitis symptom index(NIH-CPSI)、Eysenck personality qusetionnaire( EPQ)and the self-de-signed medical order compliance questionnaire and the patients' disease characteristics and personality were also analyzed.The related factores of medical order compliance in patients were analyzed through hierarchical multiple regression analysis. Results Patients with chronic pwstatitis were younger and their disease condition was seri-ous. Their personality was introverted. They had many psychological problems, such as anxiety, depression, sus-pect, et al. All these were related with patients' compliance. Conclusions Attention should be paid to the patients' personality, and psychotherapy should be given to patients with introverted personality to improve pa-tients' compliance,so that the treatment effect will be increased for patients with chronic prostatitis.

Objective To establish a gas chromatography method which will be suitable for determination of one time of the benzene, toluene, dimethylbenzene in the adhesives. Methods DMF was used for dissolving the sample, polyethylene glycol chrom-atographic column, hydrogen flames detector gas chromatography were employed to separate the compounds, determine the nature of serve time, quantify apex area. Results The contents of benzene, toluene, dimethylbenzene in gooey were 7.33-146.50, 7.23-144.50 and 7.21-144.20 mg/L respectively, with a good linear relativity (r=0.999), the rate of recovery were 96.45%-100.09%, 98.45%-100.76%, 97.81%-100.14%, the detection limits of the three chemicals were 0.22, 0.24 and 0.24 mg/L respectively, RSD were 1.60%-2.85% . Conclusion The method is accurate, feasible and suitable for determination of the benzene, toluene, dimethylbenzene in the adhesives.

Objective:To develop an HPLC method for the content determination of paeoniflorin, tetrahydropalmatine and osthole in Gujinwan capsules. Methods:The determination was performed on an Eclipse XDB-C18 column (250 mm × 4. 6 mm,5 μm) with the mobile phase consisting of 0. 1％ phosphoric acid (adjusting pH to 6. 6 with triethylamine)-acetonitrile with gradient elution. The flow rate was 1. 0 ml·min-1 . The column temperature was 30 ℃. The detection wavelengths were set at 230 nm and 280 nm. Re-sults:The calibration curves were found to be linear within the range of 9. 56-33. 65 μg· ml-1 for paeoniflorin(r=0. 9998), 3. 65-12. 86 μg· ml-1for tetrahydropalmatine(r=0. 9999) and 5. 81-20. 45 μg· ml-1for osthole(r=1. 0000). The average recovery of paeoniflorin, tetrahydropalmatine and osthole was 98. 8％(RSD=1. 1％), 98. 4％(RSD=0. 8％) and 99. 1％(RSD=1. 4％)(n=6),respectively. Conclusion:The method is simple, accurate and reproducible, which can be used for the quality control of Gujinwan capsules.

CENP-Fisacell-cycledependentkinetochoreprotein,whoseexpressionandlocalization patterns are regulated in a cell cycle-dependent manner.CENP-F plays an important role in the development and progress of malignant tumor.The expression of CENP-F is up-regulated in many tumors.It serves as an important marker in cell proliferation.Studies have demonstrated that CENP-F is involved in tumor genesis, progress,invasiveness,relapse and prognosis.CENP-F might be a valuable prognostic marker and potential therapy target in cancer treatment.
