1.Importance of secondary exploitation for Chinese materia medica in traditional Chinese medicine field
Chinese Traditional and Herbal Drugs 1994;0(07):-
To explore the Chinese materia medica (CMM) for the second time has been attached increasingly importance in recent years. The author discusses the importance of the secondary exploitation to the development of traditional Chinese medicine (TCM). At the same time, the author analyzes the current situation of TCM, and points out that the advantages and disadvantages of TCM. They are complicated with each other, and this complicated situations have brought about the difficulties of development of TCM. So the author brings forward that the secondary exploitation for CMM is a positive approach to solve the current problems, for it not only adapts to the complexion of exploring the new drug, but also keeps inherent characteristic of TCM, and aims at the disadvantages of the traditional techniques of TCM. In addition, the author recounts the method of secondary exploitation for CMM from choosing the object, deepening the base research to reforming the techniques. In the end, the author tables some proposals for the secondary exploitation for CMM.

Objective:To investigate the gene expression variety of different genotype of F-ATPase subunit uncEBF in Streptococcus mutans (S.mutans) and to evaluate the relationship among uncEBF gene expression levels, genotypes and the acidurance ability of S.mutans. Methods:The relative expression quantity of uncEBF gene against the housekeeping gene recA was determined by the two-step method of semi-quantitative RT-PCR in 18 clinical isolates of S.mutans(7 with genotype A uncEBF and 11 with genotyp B,10 with high acidurance and 8 with low). A gel documentation system and QUANTITY ONES software were used to assay the data. Results:uncEBF mRNA expression level in the isolates with genotype A uncEBF was higher than that in those with genotype B(P

Purpose: To observe the therapeutic effect of plum-blossom-magnet-needle synthetic therapy on benign prostatic hyperplasia (BPH). Method: 219 cases of BPH patients were randomly divided into two groups. There were 149 cases in treatment group, which treated by pressing, needling with plum-blossom-magnet-needle and putting effect-increasing pads on Prostate Reflex Area, bilateral Zhongliao (BL 32), Neck 1, Neck 7, Mingmen (GV 4) and Yongquan (KI 1). There were 70 cases in control group, which treated by orally taken Terazosin Hydrochloride (Gaoteling) tablets, 2 mg/time, twice a day. The therapeutic course was 4 weeks.After one therapeutic course, the therapeutic effect was evaluated. Results: The marked effect rate was 63.3% and total effective rate was 91.8%; in the control group, there were no markedly effective cases and the total effective rate was 72.7%. There was a significant difference between two groups (P<0.05). Conclusion: The plum-blossom-magnet-needle synthetic therapy had a significant therapeutic effect for the treatment of benign prostatic hyperplasia (BPH), so it was a safe and effective therapy for BPH.

Antimicrobial peptides ( AMPs) are a kind of micromolecular peptides with antibacterial , antivirus and anti-tumor activities.Unlike conventional antibiotics , acquisition of resistance by a sensitive microbial strain against AMPs is surprisingly improbable .AMPs are not widely used clinically due to their toxicity , susceptibility to proteolysis and high manufacturing cost .Researchers have obtained some AMPs with high activity and low toxicity by structure modifications . The molecular design of AMPs as well as their development in the future are reviewed .

As a normative technical term, “nine needles” appears repeatedly inThe Internal Canon of Medicine, in which Miraculous Pivot set theNine Needles and Twelve Source Acupoints as the first passage. Therefore, the significance of “nine needles” is evident. This article expounded “nine needles” from the following six aspects:the origin, the name, the types, the functions, the use and the application, with a purpose to standardize the contents of “nine needles”, and analyse the connotation.

Objective To investigate the relationships between occupational coping self-efficacy, job stress and core competence of nurses. Methods A total of 493 registered nurses were recruited in the survey with the Chinese nurse job stressors scale, occupational coping self-efficacy scale for nurses and competency inventory for registered nurse (CIRN). The correlations were analyzed using Pearson correlation analysis. Results The total scores on occupational coping self-efficacy, job stress of nurses and core competence of nurses were (31.94 ± 6.39), (90.29 ± 17.41) and (159.93 ± 34.31), respectively. Nurses′occupational coping self-efficacy negatively correlated with (r=-0.267, P<0.01) and positively correlated with the core competence of nurses (r=0.355, P<0.01). Conclusions The occupational coping self-efficacy of the nurses can be improved by successful experiencing, verbal persuasion and positive feedback. In this way, nurses core competence can be enhanced and their job stress can be relieved and consequently the quality of nursing can be enhanced.

Resveratrol synthase (RS) plays a key role in resveratrol (Res) biosynthesis. RS gene has been formerly reported to be transformed into many plant species and microorganisms, and to play certain roles in metabolic and regulation processes. In this paper, the transformations of RS gene in plants, and the related changes of biological properties, such as metabolites, anti-pathogen activities, anti-radical properties, and developmental characters in transgenic plants, as well as the production of resveratrol in microbes by utilizing RS gene were summarized. Moreover, the application prospects of RS gene in bioengineering were also addressed.

Objective:To prepare capsaicin liposomes and study the feasibility by in vitro percutaneous penetration test. Meth-ods:Capsaicin liposomes were prepared by a film-ultrasonic method. The best formula was screened by orthogonal test based on single factor studies with the entrapment efficiency as the index. The improved Franz diffusion cells were used to study the transdermal pene-tration of capsaicin suspensions, capsaicin liposomes and capsaicin ointments, and the cumulative penetration amount through the isola-ted rat skin was compared. Results:The optimal formula of capsaicin liposomes were as follows:the ratio of capsaicin to lipids was 1∶5;the amount of Tween-80 was 100 mg;the amount of vitamin E was 50 mg;10 ml dichloromethane was used as the solvent. The op-timal pH value of the external phase was 6. 5 with the volume of 10 ml. The ultrasonic time was 8 min. The order of 12-hour cumulative penetration amount was capsaicin liposomes>capsaicin-PBS suspensions>capsaicin ointments. Capsaicin liposomes had the highest 12-hour cumulative penetration amount and showed obvious sustained-release property. Conclusion:Capsaicin liposomes have high en-trapment efficiency, good percutaneous penetration and sustained-release property, and the preparation technology is simple.
