A rapid and sensitive method has been developed for the simultaneous determination of four selenium species Se(Ⅵ), Se(Ⅵ), selenomethionine, and Se-methylselenocysteine in Se-enriched yeast by liquid chromatography-hydride generation atomic fluorescence spectrometry (HPLC-HG-AFS). The isolation of the analytes from yeast samples was accomplished by proteaseⅩⅣ and trypsin enzymatic digestion. The target compounds were separated on a PRP-X100 anion exchange column and analyzed by HG-AFS. The mobile phase was 20 mmol/L (NH4)2HPO4. Good linearity was obtained for all the selenium species, with linear correlation coefficients higher than 0. 9996. The LODs of the four species were between 0. 5 and 5. 0 μg/kg. Average recoveries for the four analytes were in the ranges of 82 . 5%-101 . 2%, with intra-and inter-day RSD lower than 8. 6% and 14. 5, respectively. The proposed analytical method is simple, sensitive, with low operation cost, making it applicable for the determination of the selenium species in Se-enriched feeds.

OBJECTIVETo compare the efficacy difference in treatment of myofasical pain syndrome between sparrow-pecking moxibustion and acupuncture at trigger points so as to provide the reference of the effective therapeutic method for myofascial pain syndrome.
METHODSNinety patients were randomized into a sparrow-pecking moxibustion group and an acupuncture group, 45 cases in each one. The trigger points were selected in pain areas in the two groups. In the sparrow-pecking moxibustion group, the sparrow-pecking moxibustion was applied, 30 min in each time. In the acupuncture group, the filiform needles were inserted obliquely at 45 degrees and retained for 40 min in each treatment. The treatment was given once a day and 10 treatments made one session in the two groups. The short-form McGill pain questionnaire was used as the observation index, and the changes in pain rating index (PRI), present pain intensity (PPI) and visual analogue scale (VAS) before and after treatment were used for efficacy assessment.
RESULTSThe results of PRI, PPI and VAS after treatment were reduced apparently as compared with those before treatment in the sparrow-pecking moxibustion group and the acupuncture group (all P<0.001). The differences in PRI, PPI and VAS after treatment were not significant in comparison of the two groups (both P>0.05). The curative and remarkably effective rate was 80.0% (36/45) in the sparrow-pecking moxibustion group, which was better than 40.0% (18/45, P<0.001) in the acupuncture group.
CONCLUSIONSparrow-pecking moxibustion at trigger points achieves the superior efficacy on myofascial pain syndrome as compared with acupuncture at trigger points. This therapy is simpler in operation additionally.

Objective To explore the effects of Kangshuaiyizhi capsule on ChAT/AchE and NE, DA and 5-HT levels in the brain tissue of aging model rats, and explore its effect of protecting cerebral function. Methods Totally 72 rats were randomly divided into normal group and model group. The subacutely aging model rats were made by injecting D-gal (0.125 g/kg) into abdominal cavity continually, then aging rats were divided by random number table into model group, Naofukang group and Kangshuaiyizhi high-, low-dose group. After intervented with correspongding drugs for 60 days, activity of ChAT and AchE, cerebral cortex NE, DA, and 5-HT levels were detected. Results Activity of AchE was much higher (P<0.05), but level of ChAT, NE, DA and 5-HT in model group were significantly downregulated compared with normal group (P<0.05). After treated with Kangshuaiyizhi capsule, activity of AchE was downregulated, ChAT, NE, DA and 5-HT levels were significantly upregulated (P <0.01, P <0.05). Conclusion Kangshuaiyizhi capsule can regulate cholinergic and monoamine neurotransmitter levels in the brain tissue of aging model rats, and play a very important role in protecting cerebral function.

Objective To retrospectively evaluate the mammographic features of breast ductal carcinoma in situ (DCIS)and DCIS with small invasive foci,and to analyze the correlation between the mammographic findings and the prognostic biologic factors.Methods The mammographic examination was performed in 95 consecutive women with breast DCIS(n = 50)and DCIS with invasive foci(n = 45 ).The prognostic biologic factors including progesterone receptor(PR),C-erbB-2,and p53 were evaluated in 62 of 95 cases.Categorical data were expressed as percentages and analyzed by using the X~2 test,and furthermore the odds ratio was measured.Results(1)Only one abnormality was seen on mammography in 62 patients. Combined two abnormalities on mammography were seen in 26 patients.Mammograms were normal in 7 patients.(2)Calcifications with or without other abnormality were noted in 62 cases.Of them,73% (n =45)had higher probability of malignancy calcifications and the others were intermediate concern calcifications.Clustered calcifications(36 lesions)was the most common distribution,which usually accompanied by another abnormality.And then were segmental(18 lesions)distributed pattern.As far as the shape of mass (n = 22)was concerned,the oval shaped lesion(13 cases)was the most common,and the margin of the mass appeared as ill-defined in 15 eases,microlobulated in 1,circumscribed in 4,and obscured in 2,respectively.Isodensity mass had a higher frequency in this group(12/22,55%).Other non-calcification findings included architecture distortion(7 cases),local asymmetry (15 cases),global asymmetry (5 cases),and solitary dilated duct (3 cases),and most of them accompanied with other signs. (3)For expression profile of the biological factors,significant differences were found among malignant calcification group,intermediate concern calcification group,and non-calcification group. The odds of PR positive for the lesions noted as non-calcification were 11.00 times higher (X~2 =8.571 ,P=0.003 ;95% CI, 1.998—60.572)than the lesions noted as intermediate concern calcifications,and 8.80 times higher (X~2 = 9.748,P=0.002 ;95% CI,2.024—38.253)than the lesions noted as malignant calcifications.The odds of C-erbB-2 positive for the lesions showed as malignant calcifications were 12.35 times higher (X~2=7.353, P=0.007 ;95% CI,1.447—105.443)than the lesions showed as non-calcification,and 5.74 times higher (X~2=4.977,P = 0.026;95% CI,1.110—29.645)than the lesions showed as intermediate concern calcifications.Conclusion The mammographic features of DCIS and DCIS with small invasive foci were characteristic.Mammographic findings could be a prognostic markers,which could provide a possibility for making a treatment plan.

Objective: To discuss the application principle in tuina manipulation for lumbar intervertebral disc herniation (LIDH) in Chinese literatures published in recent 30 years. Methods: The three major Chinese databases, Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and China National Knowledge Infrastructure (CNKI), were searched to collect the studies of tuina manipulations in treatment of LIDH published in recent 30 years. Clustering analysis was applied to analyze the top 20 tuina manipulations for LIDH. Results: The top 20 most frequently used manipulations for LIDH were Gun-rolling, Rou-kneading, Dian-digital pressing, oblique Ban-pulling, An-pressing, Tanbo-plucking, Bashen-pulling and extending, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Dou-shaking, Yao-rocking, Ca-scrubbing, Pai-patting, post-extension Ban-pulling, Mo-rubbing, Zhen-vibrating, Nie-pinching, fist-back Ji-tapping, and dorsal Shen-extending methods. The involved manipulations can be divided into two categories by the treated body areas. One category is applied to the soft tissues, including Gun-rolling, Rou-kneading, Dian-digital pressing, An-pressing, Tanbo-plucking, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Ca-scrubbing, Pai-patting, Mo-rubbing, Zhen-vibrating, Nie-pinching, and fist-back Ji-tapping methods. The other category is applied to bones and joints, including oblique Ban-pulling, Bashen-pulling and extending, Dou-shaking, Yao-rocking, post-extension Ban-pulling, and dorsal Shen-extending methods. Conclusion: Based on the treated body area, the tuina manipulations applied to treat LIDH are predominated by the ones performed on soft tissues, assisted by those on bones and joints. From the way of force exertion, the involved manipulations are majorly the swinging methods, followed by squeezing and pressing ones. The manipulations applied to bones and joints are predominated by the Ban-pulling ones, followed by the Bashen-pulling and extending ones.
