Objective To find the chemical elements whose contents are abnormal in the soil of the high prevalence areas of birth defects in Shanxi Province. Methods 131 soil samples were collected from the high and low prevalence areas of birth defects respectively in 2005, the contents of 16 elements were determined with inductively coupled plasma (ICP)machine. The data were analyzed with regression and nonparametric tests. Results The total content of elements in the soil of the high prevalence areas was significantly higher than that of the low prevalence area. Compared with the low prevalence area, in a high prevalence area, the content of Mo, As, Pb, Ni, V and Se in soil was abnormal, Mo, As, Ni and Pb showed a significant relationship to the prevalence rate of birth defects, in another high prevalence area, the content of Sn, Se, Mo, Zn, Sr, Pb, Ni, Fe, V, Ca, Cu, Al, Mg and Na was abnormal, Pb, Mg, Ca, Al and Zn showed a significant relationship to the prevalence rate of birth defects. Conclusion Maybe the abnormal content of Mo, As, Ni, Pb, Mg, Ca, Al and Zn in the soil is one of the risk factors for birth defects.

This study was aimed to establish X-ray diffraction (XRD) Fourier fingerprint of mineral Chinese medicine Actinolitum, in order to provide a new method for evaluating the quality of Actinolitum. Actinolitum samples were analyzed by the technology of powder XRD. And the XRD Fourier fingerprint was determined. Accord to the fingerprints and the intensity of each characteristic peak in XRD patterns of Actinolitum, the similarity of different samples were calculated using the law of cosines and the correlation coefficient method. Systematic cluster analysis was also used for the data. The results showed that XRD patterns of 10 certified products, 3 doping products and 2 counterfeits of Actinolitum were obtained. The geometric and topological characteristics of 10 certified products were consistent. XRD fingerprint of Actinolitum from 10 certified products had 18 common characteristic peaks. The similarity analysis showed that the similarity of XRD patterns common peak of certified products were higher among 15 samples (> 0.98). The similarity of doping products was slightly lower (0.85-0.97). And the counterfeits had the lowest similarity (< 0.2). These three had significant differences which can be distinguished. The results of cluster analysis were consistent with the similarity analysis results. It was concluded that XRD fingerprint had good specificity and feasible. It was accurate and reliable, which can be used to distinguish and evaluate Actinolitum.

OBJECTIVE: To explore the nature of pathology of sluggishness of lung-defensive qi and to offer objective experimental indexes for weifen syndrome (defensive phase syndrome). METHODS: According to the completely random design, the plasma levels of vasoactive intestinal peptide (VIP) and thromboxane B2 (TX2) of 19 patients with weifen syndrome and 13 patients with qifen syndrome (qi phase syndrome) were detected by radioimmunoassay. The plasma levels of VIP and TX2 at different stages of weifen syndrome and qifen syndrome were observed. RESULTS: The plasma levels of VIP in weifen syndrome and in the late stage of weifen syndrome increased greatly at different stages as compared to qifen syndrome and the blank group (P < 0.01), while the plasma level of TX2 of weifen syndrome was higher only at the late stage than the blank group and qifen syndrome (P < 0.01). As for the levels of VIP and TX2 in weifen syndrome with different internal organs infected, there was no significant difference (P > 0.05). CONCLUSION: VIP may be an index reflecting the pathology of weifen syndrome, and it is one of the material foundations of sluggishness of lung-defensive qi, but it has nothing to do with the infected internal organs. The level of TX2 increases only after the fever of patients with weifen syndrome subsided, so it can not be the basis for diagnosis of the early stage of weifen syndrome. It doesn't increase in qifen syndrome either, the mechanism remains to be further studied.

ObjectiveTo investigate the mechanism of Atractylodis Macrocephalae Rhizoma(AMR) in the treatment of slow-transmission constipation(STC) by observing the effects of AMR on short-chain fatty acids and intestinal barries in STC mice. MethodForty-eight male KM mice were randomly divided into blank group, model group, AMR low-, medium-, high-dose groups(2.5, 5, 10 g·kg-1) and mosapride group(2.5 mg·kg-1). Except for the blank group, all groups were gavaged with loperamide suspension(5 mg·kg-1) twice daily for 14 d to construct the STC mouse model. At the same time, each drug administration group was given the corresponding drug by gavage for consecutive 14 d, the blank and model groups were gavaged with equal volume of distilled water. The effects of the treatment of AMR on body mass, defecation frequency, fecal water content and intestinal propulsion rate of mice were observed, the pathological changes of mouse colon were observed by hematoxylin-eosin(HE) staining and periodic acid-Schiff(PAS) staining, the levels of gastrin(GAS) and motilin(MTL) in serum were detected by enzyme-linked immunosorbent assay(ELISA), gas chromatography-mass spectrometry(GC-MS) was used to detect the contents of short-chain fatty acids(SCFAs) in mouse feces, real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to determine the mRNA and protein expression levels of zonula occludens-1(ZO-1), Occludin, and Claudin-1 in the colon of mice. ResultCompared with the blank group, the body mass, defecation frequency, fecal water content and intestinal propulsion rate of mice in the model group were significantly decreased(P<0.05, P<0.01), the arrangement of colonic tissues was disordered, and the number of goblet cells was reduced, the levels of GAS and MTL in serum were significantly decreased(P<0.01), and the levels of SCFAs in the feces were on a decreasing trend, with the contents of acetic acid, propionic acid, butyric acid, isobutyric acid and valeric acid were significantly decreased(P<0.05, P<0.01), the mRNA and protein expression levels of ZO-1, Occludin and Claudin-1 in the colonic tissues were significantly decreased(P<0.01). The above results suggested that STC mouse model was successfully constructed. Compared with the model group, the body mass, defecation frequency, fecal water content and intestinal propulsion rate of mice in AMP administration groups all increased significantly(P<0.05, P<0.01), the mucosal layer of the colonic tissues was structurally intact without obvious damage, and the number of goblet cells increased, serum levels of GAS and MTL were significantly increased(P<0.01), the contents of SCFAs in the feces were all on a rising trend, with the contents of acetic, propionic, butyric and isobutyric acids rising significantly(P<0.05, P<0.01), the mRNA and protein expression levels of ZO-1, Occludin and Claudin-1 in the colonic tissues were significantly increased(P<0.05, P<0.01). ConclusionAMR is able to improve the constipation symptoms in STC mice, and its mechanism may be related to increasing the contents of SCFAs in the intestine as well as promoting the mRNA and protein expression levels of ZO-1, Occludin and Claudin-1 in the colon.
