This paper aims to establish a method for the determination of sulfur dioxide in sulfur fumigation Chinese herbs. Sample powder and hydrochloric acid solution were isolated by paraffin layer in order to avoid early reactions, with the generation of sulfur dioxide, headspace with airtight needle was used to transfer sulfur dioxide into gas chromatograph, and detected with thermal conductivity detector. The analytical performance was demonstrated by the analysis of 12 herbs, spiked at four concentration levels. In general, the recoveries ranging from 70% to 110%, with relative standard deviations (RSDs) within 15%, were obtained. The limit of detection (LOD) was below 10 mg x kg(-1). Standard addition can be used for low recovery samples. The method is simple, less time-consuming, specific and sensitive. Methods comparison revealed that gas chromatography is better than traditional titration in terms of method operability, accuracy and specificity, showing good application value.

A method of LC-QTOF/MS combining with chemical synthesis has been used to determine the structures of three novel bile acids from bear bile powder. Reference substances of tauroursodeoxycholic acid and taurochenodeoxycholic acid were oxidized by pyridinium chlorochromate. The products were analyzed by LC-QTOF/MS. Total 4 products including 3 isomers were predicted and identified according to the PCC oxidation theory and LC-QTOF/MS results. Bear bile powder samples were dissolved by methanol and analyzed by LC-QTOF/MS. Three unknown peaks were found and identified as 2-[[(3beta, 5beta)-3-hydroxy-7, 24-dioxocholan-24-yl]amino]-ethanesulfonic acid, 2-[[(5beta)-3, 7, 24-trioxocholan-24-yl]amino]-ethanesulfonic acid and 2-[[(5beta, 7beta)-7-hydroxy-3, 24-dioxocholan-24-yl]amino]-ethanesulfonic acid, separately, by matching their results with that of oxidation products above.

Objective To evaluate the clinical significance of the detection of the Human Papilloma Virus (HPV) DNA typing in therapy of cervical diseases. Methods 780 cases have been studied. These cases which showed HPV-DNA positive and were diagnosed by biopsy as cervical cancer or cervical intraepithelial neoplasia( CIN Ⅰ-Ⅲ) were treated by operation or physical therapy. And 6 months and 12 months after the treatment,TCT and HPV DNA test were carried out. Results The prevalence of HPV-DNA types among the 780 cases descended from HPV 16 to 52,58,18,33 and 31. Detection rates of HPV-52 and 58 were highest among the patients with CIN Ⅰ. In patients with CIN Ⅱ,CIN Ⅲ,carcinoma in situ and invasive carcinoma,the positive rate of HPV-16 was obviously higher than other genotypes,and the difference was significant (P＜0. 01 ). 520 cases were followed-up after treatment,we found that HPV-DNA subsided within 3 months to 1 year in 432 cases. 88 cases still showed the HPV-DNA positive, among this group 48 cases were cytology diagnosed as normal or inflammation,but 14 cases were ASC-US,22 cases were LSIL and 4 cases were HSIL. Cytology abnormal cases were mere often detected in patients with persistent HPV-positive than in patients with HPV-negative. Conclusion Referring patients with cervical diseases the common HPV genotypes are 16,52,58,18,33 and 31. Especially HPV-16 are closely related with cervical cancer and high-level cervical intraepithelial neoplasis. HPV-DNA turn negative in most patients in 12 months after treatment. Persistent infection of HPV-DNA is related with the pathological changes persist.

AIM: The multi-residues method was used to determine organophosphorus pesticides in traditional Chinese herbal medicines (TCHMs).METHODS: Fifty three pesticides were extracted by high-speed homogenization,and then cleaned sequentially by C_(18) and Carb/NH2 solid phase extraction (SPE) cartridges.The residues were simultaneously identified and quantified by GC-FPD equipped with dual tower,dual column and two FPD detectors.RESULTS: The analytical performance was demonstrated by the analysis of 6 TCHMs samples extracts,spiked at three concentration levels for each pesticide.In general,the recoveries ranging from 70% to 120%,with relative standard deviations (RSDs) less than 15%,were obtained.The limit of detection (LOD) for most of the targeted pesticides tested was below 0.01 mg/kg.CONCLUSION: The method has good extraction efficiency,purification effect and good reproducibility,which can be applied to the determination of organophosphorus pesticide residues in the routine analysis of TCHMs.

Objective To study the effect of mind mapping on cognitive ability in elderly with mild cognitive impairment(MCI).Methods A total of 60 elderly aged were randomly divided into training group (30 cases) and control group(30 cases).Elderly in control group received routine maintenance of living habits.The elderly in the training group received miud mapping training intensively for 30 minutes every day for 12 months.The training effects were evaluated by mini-mental state examination(MMSE) and abilities of daily living scale(ADL).Results After training,the score of MMSE in the training group( six months:25.55 ± 1.17;one year:26.30 ±1.64) were significantly higher than before intervention( P＜ 0.05 ) and higher than that of control group(24.90 ± 1.97) (P＜0.05).The score of ADL in the training group( 14.47 ±0.64) were significantly lower than before intervention( 14.47 ±0.64) and that of control group( 15.47 ± 1.19) ( P＜ 0.05).Conclusion Mind mapping training can improve the cognitive abilities of MCI older people.
