The interaction between the antibody and the corresponding target molecule determines the characteristics of immunoassay. In this study, a single chain variable fragment antibody (scFv4C7) derived from the hybridoma strain 4C7 were prepared via genetic engineering technique. The recognition properties of scFv4 C7 was determined and compared to those of the parent monoclonal antibody by indirect competitive enzyme-linked immunosorbent assay(ic-ELISA). Three dimensional structure of the scFv4C7 was presented by Swiss-Model, and sulfathiazole ( STZ) was docked to the scFv4C7 model to obtain the structure of the binding complex. The results from the ic-ELISA showed that the binding properties of scFv4C7 were comparable with the parent monoclonal antibody and STZ was almost completely buried in a deep binding pocket formed by the heavy chain and light chain of the antibody. The interaction between STZ and scFv4C7 was more closely related to the heavy chain and the complementarity-determining region ( CDR ) H3 loop played more important role than other CDR loops. The study preliminary provided the necessary structural information for the preparation of antibody with broader specificity and higher affinity.

A series of quinoline-polyamine conjugates (8a-8n) were designed, synthesized and evaluated as inhibitors of cholinesterases (ChEs). Some of these compounds had potent ChEs inhibitory activity with IC50 values at micromolar range. Compound 8n exhibited the strongest inhibition on acetylcholinesterase (AChE) with an IC50 value of 8.78 micromol x L(-1), and compound 8i showed the most potent inhibition on butyrylcholinesterase (BChE) with IC50 value of 1.60 micromol x L(-1) which was slightly better than rivastigmine. The structure-activity relationship revealed that the chain length of polyamine and linker played important roles for inhibitory activity. Molecular modeling studies showed that 8i targeted both the catalytic active site (CAS) and the peripheral anionic site (PAS) of cholinesterases.

Objective To investigate the efficacy of butylphthalide on elderly patients with acute cerebral infarction and its effect on serum uric acid,c-reactive protein,and hemorheology.Methods Elderly patients (86 cases) with acute cerebral infarction in Xi'an No.1 Hospital from January 2015 to December 2015 were randomly divided into two groups.The control group was treated with conventional symptomatic treatment of acute cerebral infarction,observation group added with butylphthalide soft capsules.The NIHSS score and efficacy of the two groups,the serum uric acid,c-reactive protein,and the change of hemorheology before and after treatment were compared.Results The effective rate of observation group was 90.70%,significantly higher than that of control group 72.09% (P < 0.05);The NIHSS score,serum uric acid and c-reactive protein levels,blood viscosity and platelet aggregation rate of two groups after treatment were significantly lower (P < 0.05),the Barthel index were significantly increased (P < 0.05),and the change of observation group were more significant (P < 0.05).Conclusion Butylphthalide has high curative effect on elderly patients with acute cerebral infarction,can reduce the level of serum uric acid,c-reactive protein and the degree of nerve function defect,improve the hemorheology and life self-care activities ability,which can protect the brain.

Colorectal cancer is currently the third most common cancer worldwide,and there are still half of the patients undergoing recurrence and metastasis after surgical treatment,so it is necessary for colorectal cancer patients to receive radiation therapy routinely.Due to the side effects brought by radiotherapy,it is of great importance to solve how to minimize the radiation dose in radiation therapy and improve radiation sensitivity.In recent years,people discovered that microRNAs can not only be involved in the origins of colorectal cancer and progress,but also play a increasingly important role in cancer radiosensitivity.MicroRNAs can regulate tumor radiosensitivity by influencing tumor microenvironment and function on target genes.DNA damage response caused by radiation includes the activation of ATM,histone modification and chromatin remodeling,cell cycle arrest,damage repair and apoptosis.microRNAs can regulate tumor radiosensitivity through above processes.This review focuses on the mechanism of microRNAs in affecting DNA damage repair and prospects the future of microRNAs in influencing the sensitivity of cancer radiotherapy in clinical application.

Chinese Traditional and Herbal Drugs 2018;49(14):3287-3291
Objective: To study the effect of rice varieties on the quality for preparation of rice-washed water. Methods: The starch contents of rice-washed water were determined by acid hydrolysis-Fehling’s solution titration with the content of starch and rice-washed water characters as indicators. The characters of rice-washed water were determined by ultraviolet visible spectrophotometric method and the adsorption was verified to explore the effect of particle size of japonica rice, indica rice, round glutinous rice, and long glutinous rice on the quality of rice-washed water. Results: The comprehensive evaluation showed that the starch content and the characters of rice-washed water prepared by long glutinous rice fine powder were the highest. Verification test proved that it had the best adsorbability. Conclusion: The rice-washed water can be prepared with the flour of long glutinous rice.

Objective To study the effects of light on body weight,learning and memory of mice.Methods Fifty mice aged 20 days were randomly assigned to one of the five groups: 200 W light group,100 W light group,60 W light group,40 W light group and normal control group,with 10 in each.They were exposed to different intensities of light 8 hours per day for 1 week.Then we monitored their body weight,examined the mean latency and inaccuracy number in step-down test,and examined the mean latency using a Morris' water maze to observe the effect of light pollution on the mice's learning and memory.Results Compared with the other four groups,there were significant decelerations of body weight increase in 200 W light group.No significant difference in body weight gain was found among the other four groups.The four light-treatment groups had no significant differences from control group in the mean latency,inaccuracy number in step-down test or the mean latency,or the mean crosses to the target in the Morris' water maze.Conclusion Short time high-intensity light can inhibit body weight increase in mice,but short-time light has no effect on the learning and memory of mice.
