An ultra-performance liquid chromatography-quadrupole/time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) combined with reference herb method was developed to rapidly screen commercial sulfur-fumigated ginseng. Sufur-fumigated ginseng reference herb was prepared using genuine ginseng by conventional procedure. Then the reference sulfur-fumigated ginseng sample was analyzed by UPLC-Q-TOF-MS/MS to identify characteristic marker components. 25-hydroxyl-Re sulfate with higher abundance was se- lected as marker compound from 8 characteristic components identified in sulfur-fumigated ginseng reference herb. The fragmentation of 25-hydroxyl-Re sulfate was extensively investigated, fragment ion m/z 879.44 with higher intensity was chosen as the characteristic ion of sulfur-fumigated ginseng. The response of ion m/z 879. 44 was improved by optimizing the MS conditions so that this ion could be used as the characteristic marker ion for screening purpose in ion extracting screening mode. The established approach was successfully applied to inspect 21 commercial ginseng samples collected from different cities in China It was found that the chemical profiles of 9 samples were similar to that of sulfur-fumigated ginseng reference herb, and the characteristic ion m/z 879. 44 of 25-hydroxyl-Re sulfate was also detected in these samples, suggesting that there were nearly 43% ginseng samples analyzed being sulfur-fumigated. This findng agreed well with the results of sulfur dioxide residues of these 21 commercial ginseng samples determined with the method documented in Chinese Pharmacopeia Compared with the method documented in Chinese Pharmacopeia, the proposed approach is more rapid and specific for screening sulfur-fumigated ginseng. SFDA of China should strengthen the enforcement to prohibit ginseng being sulfur-fumigated, so that ginseng and it preparations could be effectively and safely benefit to the health of human beings.

Objective To evaluate the feasibility of intra-utero fetal lamb surgical repair. Methods Six twin lambs underwent surgery intra-utero at 112 days of gestation (term 140～160 days). After maternal laparotomy and Hysterotomy, fetal lamb′s toe was excised or its cleft lip was repaired in one of twin. Results At 30 to 32 days post operation,five lambs were spontamcously delivered and the other was cesarean delivery to full term gestation. Fetal wounds healed without inflammation and scar formation. Conclusions The methods of fetal lamb intro utero surgical repair is feasible.

To investigate the expression of vascular endothelial cell growth factor (VEGF) and its receptors in vitreous of patients with diabetic retinopathy ( DR), and to discuss its role in the development of DR.
●METHODS: Selected 13 patients (16 eyes) with DR and 15 healthy people (15 eyes), the expression of VEGF and its receptors (fms-like tyrosine kinase-1, Flt-1 and kinase insert domain containing receptor, KDR) were evaluated by immunohistochemistry in vitreous. The levels of VEGF, the Flt-1 and KDR in vitreous of patients with DR were examined with enzyme linked immunosorbent assay (ELlSA).
● RESULTS: lmmunohistochemical staining showed that the expression of VEGF, Flt-1 and KDR in vitreous vessel membrane of patients with DR was increased significantly. And the levels of VEGF, Flt - 1 and KDR in vitreous of patients with DR were obviously higher than that in the control group (P<0. 05 or P<0. 01).
● CONCLUSlON: VEGF, Flt - 1 and KDR were widely expressed in vitreous of patients with DR, and were positively related to micro-angiogenesis of DR patients. lt proved that VEGF and its receptors played important roles in the occurrence and development of DR.

Objective To explore risk factors of different locational leukoaraiosis in elderly patients with cerebral infarction.Methods Patients were collected who aged 60 to 85 with cerebral infarctions came to the Fourth Affiliated Hospital of China Medical University and took cerebral magnetic resonance imaging (MRI) [fluid-attenuated inversion recovery (FLAIR), T1, and T2].The patients were divided into periventricular white matter changes (PVWMCs) and deep white matter changes (DWMCs), and scored by Fazekas scale, respectively.We registered past medical history, medical systems and neurological examination, blood lipids, regular blood test, and resting blood pressure measurements in the morning.Univariate analysis was used to choose risk factors which ~fected white matter changes.After that, rank multivariate logistic regression analysis was used to test risk factors of PVWMCs and DWMCs, respectively.Results There were significant age differences in both PVWMCs and DWMCs, the degree of risk was associated with age.Conclusions PVWMCs and DWMCs risk factors vary, and we should take control of risk factors actively for the elderly in order to reduce the harm arising from WMC.

Objective To investigate the status of knowledge,attitude and behavior of schistosomiasis control of rural resi-dents in Wanjiang River region after a flood,so as to provide the reference for targeted health education. Methods The multi-stage sampling was applied to select the respondents in rural residents in Wanjiang River region,and the self-designed question-naire was used to investigate the current situation of knowledge,attitude and behavior of schistosomiasis prevention and control of the rural residents. Results The total awareness rate of knowledge about the prevention and control of schistosomiasis was 47.92%. The age,education,family income,relatives and friends with medical background,and health education significantly influenced the awareness rate(χ2=12.76,89.19,18.19,50.83 and 92.60 respectively,all P<0.05). The accuracy rates of at-titude and behavior in schistosomiasis control were 62.89%and 52.37%respectively. Conclusion The awareness rate of knowl-edge about the prevention and control of schistosomiasis,and the accuracy rates of attitude and behavior in schistosomiasis con-trol of the rural residents in Wanjiang River region are all inefficient,and therefore,the targeted health education should be strengthened to decrease the risk of schistosomiasis transmission.

objective To explore the mechanism of Naotaitong granule on ischemic apoplexy by observing the effect of Naotaitong granule on ischemic apoplexy model. Methods128 rats were randomly divided into sham operation group, console group, experimental group and control group. Ischemic apoplexy model were established in all the animals. Different disposal was given to different group. In the 7 d、 10 d、 14 d、21 d and 28 d after drug administration, immunohistochemistry were used to evaluate the expression of Slit2 and VEGF. In addition, behavior alteration and HE staining were applied to evaluate the variation of brain tissue neuron. ResultsAll the animals revealed hemiplegia and cerebral tissue softened after successfully establishing apoplexy model. The morphology of experimental group and control group was improved after drug administration with softened focus obviously reduced. Longa grade of console group in the 7 d、 10 d、 14 d、 21 d and 28 d was (2.92±0.20)、 (2.58±0.20)、 (2.25±0.27)、 (1.83±0.26) and (1.42±0.20) respectively.

Objective To construct Z-score models for normal fetal heart size measurements derived from fetal echocardiography.Methods Fetal echocardiography were performed in 910 normal singleton fetuses from 14th to 40th gestational weeks.Fetal transverse heart diameter (HD),heart length (HL),heart circumference (HC) and heart area (HA) were derived from a standard four-chamber view during end diastole.Using fetal somatic sizes as independent variables and heart sizes as dependent variables,the regression analyses of the mean (M) and the standard deviation (SD) for each parameter were calculated separately.A group of fetal heart diseases were assessed using these models.Results Strong correlations were found between fetal heart sizes and somatic sizes.Linear-cubic regression equations were each fitted to the models of the means of the heart sizes,whereas linear-quadratic equations were fitted to the models of the SDs.HD (r =0.984-0.986) was a dependent variable that provided the highest correlation coefficient with all of the fetal sizes,followed by HL (r =0.981-0.984),HC (r =0.981-0.982) and HA (r =0.978-0.979).All fetuses with Ebstein' s anomaly and most with homozygous α thalassemia-1 demonstrated Z scores reflective of increased heart sizes.Conclusions The fetal heart sizes Z-scores models had been constructed.The calculation of Z-scores for heart sizes as a function of fetal somatic size is feasible and simple.They might be useful for quantitative assessment of some cardiac diseases and used as new predictive indicators for homozygous α-thalassemia-1 particularly.
