Identification of Aurantii Fructus from different growing areas based on bionic olfaction technology / 中草药

Objective To establish odor fingerprint determination method of Aurantii Fructus from different growing areas based on bionic olfaction technology, and provide the reference for the quality control of Aurantii Fructus. Methods The bionic olfactory system (electronic nose, PEN3) was used to measure the odor of Aurantii Fructus from different growing areas; The LDA (Linear discriminant analysis) method was used to determine its odor fingerprint, and the simulation for identification was realized based on MATLAB 2013. Results Although these odor fingerprints of Aurantii Fructus from different growing areas were similar, there were significant differences in peaks' value from each other. The established odor fingerprints can achieve the 96% identification accuracy between known and unknown samples. Conclusion The method is simple, accurate and repeatable, which can be used for quality control of Aurantii Fructus from different growing areas.

The preliminary efficacy of interferon-alpha and ribavirin combination treatment of chronic hepatitis C in HIV-infected patients / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>It is internationally accepted that in drug-naïve individuals with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection, chronic hepatitis C should be treated first if the CD4 cell count does not require the initiation of anti-retroviral therapy. Present paper evaluated the clinical effect and side-effect of interferon-alpha (IFN-alpha) and ribavirin (RBV) combination therapy for Chinese patients with HCV-HIV co-infection, and compared with them for HIV infection alone.</p><p><b>METHODS</b>Ten patients with HCV-HIV and 17 patients with HCV received 5 million unit IFNalpha-2b every other day intramuscularly, and 300 mg RBV triple daily by oral. Dynamic observations were made for HCV RNA and HIV RNA loads, CD4+ and CD8+ T lymphocyte counts, liver function and blood cell measurement, and the medicine side-effects.</p><p><b>RESULTS</b>After 12-week and 24-week treatments of IFN-alpha and RBV combination therapy, mean HCV RNA levels reduced 1.14 logs and 1.56 logs from the baseline at week 0 in HCV-HIV co-infection, and reduced 1.48 logs and 1.75 logs in HCV infection, respectively. The HIV RNA levels decreased 1.22 logs and 1.32 logs from the base line; however, there were no obvious different changes at T lymphocyte counts of HCV-HIV and HCV patients through 24-week treatments. Whole 27 patients showed satisfactory biochemical response to therapy. There were some mild or mediate influence-like symptoms, intestinal uncomfortable and depressed blood cell counts in early stage of the treatments. No neuropsychiatric and auto-immune disorders were found.</p><p><b>CONCLUSIONS</b>IFN-alpha and RBV combination therapy had similar anti-HCV effects during 24-week treatment for HCV-HIV and HCV infected Chinese patients, and some anti-HIV effect. There were no obvious different biochemical responses and side-effects between two groups above.</p>

Interferon-alpha and ribavirin combination therapy for co-infection of hepatitis C virus and human immunodeficiency virus / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To evaluate the clinical effect and side-effect of interferon-alpha (IFN-a) and ribavirin (RBV) combination therapy for Chinese patients with co-infection of hepatitis C virus (HCV) and human immunodeficiency virus (HIV), and to compare them with only HIV infection patients.</p><p><b>METHODS</b>10 patients with HCV-HIV and 17 patients with only HCV infection received 5 million units of IFNalpha-2b every other day intramuscularly, and 300 mg RBV orally three times a day. Dynamic observations were done for HCV RNA and HIV RNA loads, CD4+ and CD8+ T lymphocyte counts, liver function and blood cell measures, and the side-effects of the medicines.</p><p><b>RESULTS</b>After 12 weeks and 24 weeks of IFNalpha and RBV combination therapy, mean HCV RNA levels reduced 1.14 log (t = 3.843, P < 0.01) and 2.08 log (t =6.564, P < 0.01) from the baseline at week 0 in the HCV-HIV co-infection group, and reduced 1.48 log (t = 6.438, P less than 0.01) and 2.33 log (t = 7.343, P < 0.01) in the HCV infection group. Meanwhile, the HIV RNA levels decreased 1.22 log (t = 3.662, P < 0.01) and 1.73 log (t = 6.119, P < 0.01) from the base line. However, there were no obvious different changes among T lymphocyte counts of HCV-HIV and HCV patients at week 0, week 12 and week 24. All 27 patients showed satisfactory biochemical response to therapy. There were some mild or moderate influenza-like symptoms, intestinal discomfort and decreased blood cell counts in the early stages of the treatments. No neuropsychic and auto-immune disorders were found.</p><p><b>CONCLUSIONS</b>IFNalpha-2b and RBV combination therapy showed similar anti-HCV effects during the 24 week treatment for HCV-HIV and HCV infected patients, and some anti-HIV effect was also observed. No obvious different biochemical responses and side-effects were found between the above two groups.</p>
