Chinese Traditional Patent Medicine 1992;0(01):-
AIM: To establish chromatogram figerprints of fresh Magnoliae officinalis and their processed product by HPLC-DAD-MS method. METHODS: A HPLC-DAD-MS method was proposed for quality assessment of Magnoliae officinalis and their processed product,the HPLC columm,mobile phase,elution mode and gradient program were optimized in order to obtain high quality HPLC profile.HPLC analysis was performed on a LC-18 colunm(5 ?m,250 mm?4.6 mm) with the mixture of H_2O(A) and acetonitrile(B) as mobile phase in gradient mode.The colunm temperature was set up at 30 ℃ and the flow rate was 1 mL/min. RESULTS: The HPLC fingerprint was established based on the analysis of ten fresh Magnoliae officqinalis herbal samples.Twenty-two characteristic peaks were found in all ten samples.The main characteristic peaks were identified based on the comparison of UV and MS spectra of each analyte with that of authentic compounds and literature data.The HPLC fingerprint of processed Magnoliae officinalis was established.Comparing with corresponding fresh herbal samples,twent-three characteristic peaks were found in all ten processed herbal samples.Moreover,gingerol was found in processed Magnoliae officinalis. CONCLUSION: The fingerprint chromatograms from HPLC method can be used to evaluate the quality of Magnoliae officinalis and their processed products.
2.Adaptive behavior among patients with breast cancer during treatment period: qualitative research
Chinese Journal of Practical Nursing 2011;27(4):11-15
Objective To explore the characteristics and trends of adaptive behavior among patients with breast cancer during the treatment periods. Methods Phenomenological research method was used. 15 women accepted modified radical mastectomy in the Provincial Hospital of Anhui Medical University were interviewed during the whole treatment periods. Results 6 adaptive behavior models were found: over-cautiousness, compliance, escape-avoidance, specific social circles, social re-adaptation and dietary behavior change. These six behavior models dynamicly varied during the treatment trajectory. Conclusions Diagnosis and treatment of breast cancer are strong negative life events, the unalterable trauma of body and the periodic shocks by chemotherapy force patients' self-positioning shifting between "wellness"and "illness"and this shift is the main reason that caused changes of behaviors.

Objective:To evaluate the efficacy and safety of amisulpride and risperidone in the treatment of schizophrenia. Meth-ods:The RCTs literatures on amisulpride and risperidone in the treatment of schizophrenia were retrieved and screened, and the quali-fied ones were analyzed by meta-analysis. Results:A total of 10 literatures were included involving 802 patients. Meta-analysis results showed that the difference between the two groups after the treatment was not statistically significant by comparing the clinical efficien-cy, PANSS score and TESS score. About the incidence of adverse reactions, amisulpride was better than risperidone in the endocrine function, extrapyramidal symptoms, weight gain and cardiovascular system. The incidence of nausea and vomiting of amisulpride was more than that of risperidone. There was no statistical significance in insomnia, headache, dizziness and the others. Conclusion:Ex-isting literature analysis shows that amisulpride is safe and effective in the treatment of schizophrenia.

Objective To investigate the significance of antibody to Ro-52 in patients with autoim-mune liver disease(AILD). Methods One hundred and fifteen patients with abnormal liver functions, who had anti-Ro-52 detection by immunological blotting, were reviewed retrospectively. According to types of AILD, the clinical features were compared between patients with and without anti-Ro-52, respectively, κ test of concordance was used to provide a chance-corrected valve for immune-serological results. Results The rates of anti-Ro-52 in autoimmune hepatitis( AIH), primary sclerosing cholangitis(PBC) and AIH/PBC o-verlap syndrome groups were 32.43%, 24.56% and 33.33%, respectively, there were no significant differ-enees among three groups ( x2 = 0. 949, P >0. 05). The rate of anti-soluble hver antigen/liver-pancreas ( an-ti-SLA/LP) in AIH patients with anti-Ro-52 (58.33%) was higher than AIH patients without anti-Ro-52 ( 16.00% ,P < 0.05 ). The rate of anti-SLA/LP in AIH/PBC overlap syndrome patients with anti-Ro-52 (85.71%) was also higher than that of control group (28.57% ,P <0.05). Anti-Ro-52 and anti-SLA/LP had concordance according to κ test( κ >0.40, P <0.05). The average level of IgG in AIH/PBC overlap syndrome patients with anti-Ro-52 was higher than patients without anti-Ro-52 ( t = 2. 508, P < 0.05 ). Conclusion The rates of anti-Ro-52 in AIH, PBC and AIH/PBC overlap syndrome were of no significant differences. Anti-Ro-52 may have correlation with anti-SLA/LP. AIH/PBC overlap syndrome patients with anti-Ro-52 shewed higher IgG level than patients without anti-Ro-52.
