1.Research status and analysis of English translation of package instruction of Chinese medicine
International Journal of Traditional Chinese Medicine 2017;39(5):385-390
Through approaches of literature statistics and content analysis, the English translation studies of package instruction of Chinese medicine from Chinese literature database were summarized and analyzed, including China National Knowledge Infrastructure (CNKI), Wangfang Data and VIP Database. It was found that there existed four main problems in English translation of package instruction of Chinese medicine. First, there were relatively few studies in this field. Second, the papers were distributed unevenly in the relevant periodicals. Third, most studies were practice-based studies. Fourth, the research methods were simple. Theoretical guidance, research system and empirical research should be paid attention in English translation studies of package instruction of Chinese medicine.

Objective To investigate the clinical application and effect of micro-planting nail anchorage in orthodontics.Methods Fifty-six patients with oral orthodontic were randomly divided into two groups.29 patients in the observation group were used micro-planting nail anchorage,27 patients in the control group were used the strong non-implant anchorage.Results The reduction of upper incisor inclination and distance in observation group was significantly higher than control group.In another hand,displacement of molars in observation group was significantly lower than control group,the difference was significant(t =9.714,4.491,17.172,all P <0.05).Conclusion Micro planting nail can provide the ideal anchorage and orthodontic treatment,and it has the advantages of easy and flexible operation,and it can be instantly afterburner,reliable quality,worthy of clinical application and promotion.

Objective To establish a novel real-time PCR method to detect HCV RNA using Selfreporting duplex mutation primers.Methods The recombinant vector pMD18-T-HCV 5′-NCR was used as the calibrator.The Self-reporting duplex mutation primers were designed according to the gene sequence.And then the PCR reaction system was optimized and evaluated.The specificity,sensitivity and reproducibility of real-time PCR were estimated,The serum specimens from 90 cases(30 cases of HCV,30 cases of other viral hepatitis and 30 healthy volunteers) were tested with this real-time PCR; Results were compared with those obtained using a commercial TaqMan kit.Results The assay was established.It showed linearity over a wide range from 20 - 109 IU/ml.Intra-experimental coefficients of variation(CVs) were 1.37% -4.59%,and inter-experimental CVs were 1.58% -4.81%,respectively.There was no significant difference of HCV genome number tested by the two methods(R2 = 0.95) in 30 hepatitis C patients; HCV DNA was not detected in any serum samples of 30 healthy volunteers by the two methods.The specificity was 100%(60/60).All the samples in patients with clinically confirmed HCV infections showed HCV RNA positive.There wass good correlation between the quantitaive results and results obtained using the commercial TaqMan kit.Conclusions It is demonstrated that real-time PCR is a reliable,accurate and feasible assay for HCV.The establishment of this assay provided alternative technology for clinical diagnosis or therapeutic drug monitoring in the field of HCV infection and epidemiologic survey.

With polyethylene glycol vitamin E succinate (TPGS) as the carrier materials, and berberine hydrochloride ( BER) as model drug, we formed berberine hydrochloride (BER) -loaded TPGS nanomicells (BER-PMs) using filming-rehydration method to improve its solubility and in vitro anti-tumor effect. The transmission electron microscope (TEM) was used to observe the particle appearance; particle detector was used to detect the diameter and Zeta potential; and ultracentrifugation was utilized to determine the encapsulation efficiency (EE) and drug-loading (DD); dynamic dialysis method was used to study the in vitro release behavior of BER-PMs, and the anti-tumor activity against MCF-7 cells was determined by MTT method. Results showed that the average particle size of BER-PMs was (12.45 ± 1.46) nm; particle size was uniform and spherical; drug loading and encapsulation efficiency were (5.7 ± 0.22)% and (95.67 ± 5.35)%, respectively. Zeta potential was (-1.12 ± 0.23) mV; release rate within 24 h was 37.20% and 41.14% respectively in pH 7.4 and pH 6.5 phosphate buffer in vitro; compared with BER, BER-PMs can significantly inhibit MCF-7 cell proliferation (P < 0.05), promote cell apoptosis and improve the anti-tumor activity of BER in vitro. Therefore, the formed berberine hydrochloride micelle can more effectively promote the apoptosis of MCF-7 cell, and improve the drug's in vitro anti-tumor effect.

Objective To evaluate the effects of endogenous NO on the chemosensitivity of human breast cancer cell. Methods MCF-7 cells were cultured as monolayer, incubated with cytokine IL-1β. The pro-duction of NO was detected by NO assay. The expression of iNOS protein was measured by Western blotting. Establishing control group and experimental group, the chemosensitivity of MCF-7 cells incubated by L-NMMA and L-Arg to ADM and 5-Fu was studied by MTT assay. Results There was a positive correlation of dose-dependence between NO production and IL-1β concentration. MCF-7 cells expressed plenty of iNOS by induetion of IL-1β. There was no significant difference on iNOS whether L-NMMA and L-Arg existed or not. Incubating MCF-7 cells with 0. 5 μmol/L or 1 μmol/L ADM, the survival rate of experiment group was remarkablely decreased(P < 0.05) ; L-NMMA significantly increased survival rate of experiment group(P < O. 05) ; L-Arg decreased survival rate of experiment group(P < 0.05). Conclusion The induction of IL-113 in MCF-7 cells can increase the production of endogenous NO, which increases MCF-7 cells' sensitivity to chemotherapy.
