ObjectiveTo investigate the relationship between colorectal neoplasia and nonalcoholic fatty liver disease (NAFLD).MethodsData of 809 patients who had undergone colonoscopy and epigastric CT scan in the same period were reviewed for gender,age,history of diabetes,hypertension,hyperlipidemia,NAFLD,colonoscopy and pathology results.Correlation of colorectal adenoma (CRA),colorectal carcinoma (CRC) and NAFLD were studied with multivariate Logistic analysis.Results NAFLD (P ＜0.0001,OR 2.06,95％ CI 1.53-2.76) was the independent risk factor for CRA,where the incidence of CRA was higher than that in the control group.ConclusionPatients with NAFLD is the risk population of colorectal adenomas.

Nerve agents (NAs) belong to the class of organic phosphorus compounds which are acetylcholinesterase ( AChE) inhibitors, including soman, sarin, tabun,VX, etc.NAs are extremely toxic and considered as the most danger-ous chemical warfare agents.The current standard treatment for poisoning by nerve agents consists of the combined adminis-tration of anticholinergic drugs such as atropine sulphate, AChE reactivators such as pralidoxime, obidoxime and HI-6 and diazepam for anticonvulsant effects, but oximes are therapeutic antidotes against nerve agent intoxications which exert the therapeutic purposes primarily by reactivating the NAs-inhibited AChE.In this paper, the mechanism of nerve agents, the main working procedure of anti-NAs drugs, the chemical structure of classic reactivator, the corresponding antitoxic action, in vivo and in vitro effects and metabolic kinetics are reviewed.

The chemiluminescence reaction of amidopyrine-potassium permanganate with formaldehyde as an enhancer was investigated by flow injection system. A method for the determination of amidopyrine on the basis of this technique was proposed. The detection limit is 3.0×10－8 g/mL, the relative standard deviation is 1.3% (4.0×10－6 g/mL amidopyrine,n=11).The linear range is 1.0×10－7～8.0×10－5g/mL amidopyrine.　The method has been applied to the determination of amidopyrine in the antondin injection.

Objective To differentiate Chinese medical syndromes of chronic renal Failure by objective laboratory indexes. Method Data of 312 cases were collected through a retrospective survey and these cases were divided into five Chinese medical syndromes according to an authorized criterion. Laboratory examination indexes of all syndromes were disposed with analysis of variance and discriminant analysis in turn. Result Discriminant functions of four syndromes were worked out and the accuracy of the functions was 60%. Conclusion Differentiation of Chinese medical syndromes should use modern techniques for reference on the base of traditional methods. And through it, a new way even a new system of diagnosis for Chinese medical syndromes in which traditional and modern methods are perfectly combined may be found out.

Objective To determine the content of heavy metals and harmful elements in commercially available Yuanhu Zhitong Capsule. Methods The determination of lead, cadmium, arsenic, mercury, copper and chromium by atomic absorption spectrometry and atomic fluorescence spectrometry was established.Results The recovery rate of the method was between 91.2% and 111.2%, and the precision of the experiment was less than 5%, and the range of each element was good.The stability and reproducibility of the method were good.Lead and cadmium and copper of Yuanhu zhitong capsule in different degree exceeded the standard, while the content of arsenic, mercury and chromium was in accordance with the requirements. Conclusion The method is simple and easy to operate, convenient and quick.The content of the current limit of Yuanhu zhitong capsule still need to establish the quality standard of lead and cadmium, arsenic, mercury, copper and chromium.In this paper, the establishment of the heavy metals and harmful elements determination method of Yuanhu zhitong capsule provide quality control and safety evaluation of reference.

The geo-herbalism of Cangzhu, Atractylodes lancea (Thunb.) DC. , was studied for itsstrict quality control. Samples of typical and representative populations of geo-herbal and non-geo herbalorigin were collected, examined and cultivated through field work. Volatile oils from samples of varioushabitats were determined by GC/MS, and their respective bacteriostatic minimum inhibitory concentration(MIC)determined. Results of the study showed that both the size of capitulum and cleft on the leaves var-ied greatly even in species of the same population. The main components in their volatile oil also variedgreatly with Maocangzhu (MCZ) contains atractylone (29.54%) and atractylodin (17.82%); that of Nan-cangzhu (NCZ) contains hinesol (61.86%) and β-eudesmol (19.79%), and Baicangzhu (BCZ) cantains βeudesmol or mixture of β-eudesmol and atractylone (over 30%). Volatile oils of speciaes from Luotina,Taibai, and Huanglong showed potent bacteriostatic activity against Streptococcus hemolyticus (SH), com-parable to penicillin or streptomycin. In conclusion, A. lancea is a polymorphic complex greatly influencedby geographic environment and a reasonable proposal is to name them by geo-herbal names such as: MCZas A. lancea var. maoshanensis Hu et Feng; NCZ as A. lancea subsp. luotianensis Hu et Feng; and BCZ asA. lancea var. chinensis (Bunge) Kitam other than independent species as A. chinensis Bunge. It was in-correct to say that MCZ has no atractylone in its volatile oil and therefore differs from A. macrocephalaKoidz. (Baizhu). Inhibitory activity of the volatile oils against SH and Pseudomonas aeruginosa (PA) arealso quite different due to the habitats and imply that the rhizome from Luotian may be used to cure infec-tion diseases caused by SH and PA besides their traditional uses.

AIM To study the protective effect of curcumin (Cur) on PC12 cells damage induced by oxidative stress. METHODS Using H 2O 2-induced PC12 cells damage as the model of neuron damage induced by oxidative stress, the proliferation of PC12 cells was observed by 3-[4,5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide(MTT)assay, the apoptosis of PC12 cells was detected by propidium iodide stain flow cytometry (FCM), the mitochondrial membrane potential (△?m) was analyzed by rhodamine123 stain FCM and the level of reactive oxygen species (ROS) in PC12 cells was analyzed by dihydrohodamine123 stain FCM. RESULTS In the presence of Cur (20 and 40 ?mol?L -1), the inhibitory rates of PC12 cells induced by H 2O 2 from 25 to 400 ?mol?L -1 and the apoptosis of PC12 cell induced by 100 and 200 ?mol?L -1 H 2O 2 for 24 h were decreased. The level of △?m was decreased significantly in PC12 cells after 100 and 200 ?mol?L -1 H 2O 2 treatment for 24 h, however, those decreases were significantly ameliorated by Cur (20 and 40 ?mol?L -1) treatment. The level of ROS was significantly increased in PC12 cells exposed to H 2O 2 (100 and 200 ?mol?L -1) for 12 h, whereas 40 ?mol?L -1 of Cur prevented the rise induced by H 2O 2. CONCLUSIONS Cur has protective effect on PC12 cells damage induced by oxidative stress and the effect might be attributed to its removal of ROS and increase of △?m level.
