Objective:To study the content of polysaccharide and its antitumor activity in the edible part and the disused part of asparagus. Methods:A orthogonal design of 4 factors and 3 levels was applied to optimize the solvent concentration, solid-liquid ratio, extraction duration and temperature that influencing the extraction efficiency. The difference in the polysaccharides content between the two parts was compared, and the difference in the antitumor activity against MCF-7 cells was observed with SPSS software. Results:The optimum extraction technology was used. The difference in the polysaccharide content between the edible part and disused part of asparagus was significant (P<0. 05). The antitumor activity of the two refined polysaccharides against MCF-7 cells was without nota-ble difference (P>0. 05). Conclusion:There is significant difference in the content of polysaccharide in the edible part and the dis-used part of asparagus, however, there is no significant difference in the antitumor activity in the two parts of asparagus.

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.

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.

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.

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.

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.
