HuangDi NeiJing, the Yellow Emperor's Classic of Internal Medicine, a foundational classic of Chinese medical theory, is ranked as the first among the four most important classics of traditional Chinese medicine. Translation of culture-specific Lexicon is a pivot, also a nodus in translating Huangdi Neijing, so, chewing over it is of important meaning for English translation of the Chinese classic or even for that of whole Chinese medicine. In expectation of somewhat contribution to the development of the Chinese medical English discipline, the classification and translation strategy for culture-specific lexicon were discussed by the authors in this paper through an empirical study on comparing the different terms translated in two versions of Huangdi Neijing translation.

Objective To understand the influencing factors of the post competency of health technical personnel in township hospitals in a prov-ince,so as to provide scientific reference for improving health professionals'post competency. Methods Using stratified cluster random sam-pling,1242 health professionals from township health centers and village clinics of 14 cities were extracted and then surveyed with questionnaire. Results The average score of the respondents'post competency was 3.43,which meant they could afford most of the work. Multiple linear re-gression analysis showed that the main influencing factors of the professionals'post competency included gender,age,specialty,and training. The female,senior,nursing and health-care professionals with training exhibited a better post competency. Conclusion To realize the further develop-ment of professionals'post competency,medical students should not only be early clinical and more clinical,but also actively participate in the training and continue the education after entering the clinic. On the other hand ,the government should define the function orientation of the town-ship healthy centers and explore human resource management mode based on the post competency.

OBJECTIVE: To study the effect of Danshen injection and Xinkeshu tablets on the metabolism of CYP1A2, CYP2C9, CYP2C19, CYP2D6 and CYP3A4 in rabbits by cocktail probe substrates method. METHODS: Sixteen healthy fasted male rabbits were simultaneously given cocktail probe substrates including caffeine, tolbutamide, omeprazole, dextromethorphan and midazolam. The metabolic rates of cocktail probe substrates were determined by LC MS/MS methods at some specific time following the administration. Then the rabbits were randomly assigned to receive either Danshen injection or Xinkeshu tablets. The whole self-control trial was consisted of 3 cycles. The low, middle and high dosage (0.5, 1 and 2 mL · kg^-1) of Danshen injection group would be administrated in 3 cycles in sequence. The low, middle and high dosage (90, 180 and 360 mg · kg^-1) of Xinkeshu tablets group would be administrated in 3 cycles in sequence. Each cycle includes wall-out period of 7 d followed by administration of the 2 herbal medicines for consecutive 7 d. On the 15th day the cocktail probe substrates were administrated and the metabolic rates were determined. The differences of the metabolic rates between after and before admininstration of the 2 herbal medicines were assessed by one-way analysis of variance (ANOVA). RESULTS: After taking the agents of Danshen injection and Xinkeshu tablets, the metabolic rates of the five cocktail probe substrates had a tendency to decline compared with the before-administration. CONCLUSION: The outcome in vivo is in accordance with that in vitro. Danshen injection and Xinkeshu tablets can inhibit the metabolism of five CYPs (1A2, 2C9, 2C19, 2D6 and 3A4) activities in rabbits. At sometimes precautions are needed to co-administrate either Danshen injection or Xinkeshu tablets for-possible herb-drug interactions.

The dynamic changes of germination percentage, germination potential, thousand-seed weight, antioxidase activity in Desmodium styracifolium seeds with different storage time were tested, and electrical conductivity, contents of soluble sugar, soluble protein, starch in seed leach liquor were also determined in order to reveal the mechanism of seed deterioration. The results as the following. (1) The germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds declined, while the seed coat color darkened with the extension of storage time. (2) The activities of superoxide dismutase (SOD) and peroxidase (POD) decreased with the prolongation of storage period. The SOD activity declined fastest in 1,095-1,185 d of storage, while the POD activity declined significantly in 365-395 d of storage. (3) The electrical conductivity and the contents of soluble sugar, starch in seed leach liquor increased, while the content of soluble protein declined with the extension of storage time. (4) Correlation analysis indicated that the germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds have a significantly positive correlation with SOD and POD activity, while have a significantly negative correlation with the electrical conductivity, contents of soluble sugar and starch. It can be concluded that during the storage of D. styracifolium seeds, physiological and biochemical changes including decrease in antioxidase activity, rise in electrical conductivity, degradation effluent of soluble sugar and starch, degradation of soluble protein were the main factors leading to the seed deterioration.

Objective The study was to compare the effect of sufentanil and morphine preconditioning on ischemia /reperfusion-induced ventricular arrhythmias and the expression and distribution of myocardial Cx43 in rats.The regulation mechanisms that how sufentail and morphine lead to the change of Cx43 were also studied.Methods 32 male SD rats were randomly divided into 4 groups:sham operation group (group C),ischemia/reperfusion (group I/R),morphine preconditioning group(group M) and sufentanil preconditioning group(group S),each group had 8 rats.Established myocardial ischemia/reperfusion model,continuous recorded Ⅱ ECG,mean arterial pressure(MAP) and heart rate(HR).The ventricular arrhythmias at the 30 min before reperfusion was observed and the ventricular arrhythmias score of each group was calculated by ECG analysis; expression and distribution of Cx43 protein were observed by immunohistochemical technique.Results Compared with group C,the HR,MAP,RPP of group I/R were decreased obviously (P ＜ 0.05),while the arrhythmia score was significantly higher(P ＜ 0.05).Compared with group I/R,the extent of the declined of HR,MAP,RPP of group M and group S were eased significantly(P ＜ 0.05) and arrhythmia score was significantly lower(P ＜ 0.05).The HR,MAP,RPP of group M and group S are closer(P ＞ 0.05).Compared with the group C,Cx43 expression level in group I/R was significantly reduced (P ＜ 0.05) and the distribution was disordered,while compared with the group I/R,Cx43 expression level in group M and group S were significantly increased (P ＜ 0.05),and its distribution was structured.In group M and group S,Cx43 expression level were closer(P ＞ 0.05) and so as their distribution.Conclusion Sufentanil and morphine could inhibit the reduction of myocardial Cx43 expression level and improve its distribution which could played an important role in anti-arrhythmic during ischemia-reperfusion.

OBJECTIVETo determine the role of asymmetric dimethylarginine (ADMA) in acute lung injury induced by cerebral ischemia/reperfusion (I/R) injury in rats.

METHODSAdult male SD rats were randomly divided into 4 groups, namely the sham-operated group (S), cerebral I/R model group, ADMA+I/R group, and dimethylarginine dimethylaminohydrolase (DDAH)+I/R group. In the latter 3 groups, acute lung injury was induced by left middle cerebral artery occlusion for 120 min. After a 24-h reperfusion, the rats were sacrificed and the activities of nitric oxide synthase (NOS) and contents of nitric oxide (NO) were measured using reductase and colorimetric assay. The mRNA and protein expressions of protein kinase C (PKC) and myosin light chain kinase (MLCK) in the lung tissues were detected with RT-PCR and Western blotting, respectively. The contents of ADMA in the bronchoalveolar lavage fluid (BALF) and blood flowing into and out of the lungs were measured by ELISA.

RESULTSCerebral I/R injury caused significantly elevated ADMA levels in the BALF and blood flowing into the lungs, and obviously lowered the NO concentration and NOS activity in the lung tissues (P<0.05). Following cerebral I/R injury, MLCK and PKC mRNA and protein expressions were significantly upregualted in the lung tissues (P<0.05). Exogenous DDAH obviously decreased the levels of ADMA in the BALF and blood flowing into the lungs, increased NO concentration and NOS activity, and down-regulated MLCK and PKC mRNA and protein expressions in lung tissues of rats with cerebral I/R injury (P<0.05).

CONCLUSIONADMA contributes to the development of acute lung injury following cerebral I/R injury in rats by upregulating MLCK and PKC expression. ADMA may serve as a novel therapeutic biomarker and a potential therapeutic target for acute lung injury induced by cerebral I/R injury.
