Objective To explore the anti-cancer function of old drugs from the perspective of the concept of Chinese herbal nature combination, and provide method and a new thinking style for the new function discovery from old drugs under the guidance of the theory of traditional Chinese medicine (TCM). Methods Using lung cancer with qi and yin deficiency as the example, the therapeutic principles of TCM anti-lung cancer treatment were analyzed and Chinese herbal nature combination patterns (CHNCP) for cancer treatment were extracted based on the relationship between function and Chinese herbal nature combination. The chemical medicines were re-screened with the cancer CHNCP and the candidates were identified. Results The therapeutic principle of TCM anti-lung cancer treatment is invigorating qi and nourishing yin. Fifteen chemical medicines were identified as the anti-cancer candidates, including 2 anti-cancer drugs being used in clinics and 4 drugs having the anti-cancer activity. Conclusion The method for finding the anti-cancer function of old drugs based on the Chinese herbal nature combination is feasiable, which provide new clues for application of old drugs.

It is significant for theory and application to study on marine microbial exopolysaccharides with differential structures and activities endowed by the specific marine environment.The recent progress of the research on the structures and bioactivities of marine microbial ex- opolysaccharides was reviewed,and the prospect of the research and development of the marine microbial exopolysaecharides was also expec- ted.

On the basis of the development of a new CE method for the analysis of α-lactalbumin (α-Lac), β-lactoglobulin A(β-LgA) and β-lactoglobulin B(β-LgB), different concentrations of acetic acid (HAc) and trichloroacetic acid (TCA) for the removal of proteins in raw milk, infant formula A and B, and yogurt were investigated.It was shown that TCA is better than HAc for eliminating of proteins in the above four samples.The proteins in 2 g of raw milk could be eliminated by 3 mL of 100 g/L TCA.0.5 g of infant formula A and B needs 5 mL of 10 g/L and 20 g/L TCA to remove the proteins, respectively.For 2 g of yogurt, 3 mL of 20 g/L TCA is enough.The present research may provide valuable information for protein-containing sample (such as raw milk, infant formula and yogurt) pretreatment.

Medical genetics is one of the important basic courses in medical education. The teaching reform in course content, teaching method and experimental teaching was carried out to arouse their enthusiasm in study, cultivate their capabilities of analyzing of medical practice problem.

Objective To investigate the effect of repeated ketamine administration on long-term potential ( LTP) in area CA1 of hippocampus. Methods Thirty SD rats of either sex aged 35-45 days were randomly divided into 2 control groups (C) and 3 ketamine groups (K). The animals in control groups received intraperitoneal (IP) normal saline (NS) 2 ml once (C1) or once every 3 days?5 times (C2); while in ketamine groups received IP ketamine 70 mg?kg-1 in 2 ml NS once (K1) or once every 3 days ?3 times (K2) or ? 5 times (K3). Seven days after the last injection the animals were killed and hippocampus slices were prepared. Electrical stimulation was delivered to the Schaffer commissural fiber system and extracellular recoding was performed at the pyramidal cell layer in hippocampal slices. LTP and population spike amplitude (PSA) after tetanus stimulation were measured and recorded.Results There was no significant difference in both PSA after tetanus stimulation and the induction ratio of LTP in area CA1 of hippocampus slices between group C1, C2 and K1. But the PSA and induction ratio of LTP were significantly decreased in group K3 as compared with group C1 and C2 ( P

Objective To design a private cloud storage system to guarantee intranet and internet data security and realize data sharing between multi platforms.Methods The idea and solution for building the system were proposed by analyzing the difficulty during hospital informatization.The infrastructure based on the idle computing resources in the existing virtual pool and the application platform by private cloud storage software were involved in the development of the system,and related software and hardware were integrated after adjustment and customization,and then the system came into being with easy operation and high performance-cost ratio.Results The system developed realized freely data storage and sharing,and implemented file encryption to control the applied range.Conclusion The system has the functions of malicious code scanning,cooperative office system and data auto-backup,synchronization,transmission,sharing and etc,which executes intranet and intemet data sharing based on physical isolation.

Objective To detect the expression of Th17 levels about peripheral blood in patients with bron-chial asthma in bronchoalveolar lavage fluid,and to investigate its effect in pathogenesis of bronchial asthmaand. Methods Patients with acute bronchial asthma from 2014 April to 2014 November were collected in the experiment. There are 52 cases as observation group (group of patients with asthma),and the patients were then divided according the severity (mild,moderate,severe);in addition,select 50 healthy people in the same period in our hospital as con-trol group healthy control group.Collect peripheral blood and bronchoalveolar lavage fluid,the expression of specific transcription factors ROR gamma T and cytokine IL -17 in the peripheral blood and bronchoalveolar lavage fluid in Th17 cells levels were detected by real -time fluorescent quantitative PCR.Results The expression of IL -17,ROR gamma T in peripheral blood and bronchoalveolar lavage fluid of the observation group were higher than the control group;the expression of IL -17,ROR gamma T in alveolar lavage fluid quantity and peripheral blood with severe patients in the observation group were higher than that in the mild patients,differences were statistically significant (P <0.05).Conclusion There are 17 auxiliary T lymphocytes in patients with bronchial asthma in vivo (Th17) advantage of expression,Th17 may play an important role in the pathogenesis of bronchial asthma.Bronchial asthma patients body may have advantage to heip expression of T lymphocytes 17 (Th17).Th17 may play an important role in the pathogenesis of bronchial asthma.
