Objective:To observe the effect of warm-unblocking acupuncture plus fluticasone propionate nasal spray on the pulmonary ventilation, level of interferon-γ (IFN-γ) and sleep quality in patients with allergic rhinitis (AR). Methods: A total of 112 AR patients were enrolled between January 2013 and August 2018 and were divided into an observation group and a control group by the random number table method, with 56 cases in each group. Patients in the observation group received warm-unblocking acupuncture plus fluticasone propionate nasal spray, and patients in the control group only received fluticasone propionate nasal spray. The nasal symptom score, pulmonary function indexes, the levels of IFN-γ and interleukin (IL)-4 in serum, and sleep quality in the two groups were compared. Results: After treatment, the total effective rate in the observation group was higher than that in the control group (P＜0.05). The nasal symptom score dropped in both groups after treatment (both P＜0.05), and the score in the observation group was lower than that in the control group (P＜0.05). The pulmonary ventilation indexes all increased significantly after treatment in the observation group (all P＜0.05); the forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio (FEV1/FVC) and the forced expiratory flow at 50%, 75% and 25%-75% of the vital capacity (FEF50%, FEF75%, FEF25%-75%) increased after treatment in the control group (all P＜0.05); the pulmonary ventilation indexes were higher in the observation group than those in the control group (all P＜0.05). The level of IFN-γ increased significantly after treatment in the two groups (both P＜0.05) and the level of IL-4 dropped significantly (both P＜0.05); the observation group had a higher IFN-γ level (P＜0.05) and a lower IL-4 level (P＜0.05) compared with the control group. Regarding the Pittsburgh sleep quality index (PSQI), the scores of subjective sleep quality, habitual sleep efficiency and sleep disturbances and the general PSQI score decreased significantly after treatment in both groups (all P＜0.05), and the scores in the observation group were significantly lower than those in the control group (all P＜0.05). Conclusion: Warm-unblocking acupuncture plus fluticasone propionate nasal spray can effectively control the clinical symptoms and improve pulmonary function in the treatment of AR; this approach can regulate the levels of IFN-γ and IL-4 towards the normal range in AR patients; it can also improve patient’s sleep quality. This method can produce more significant efficacy than fluticasone propionate nasal spray used alone.

OBJECTIVETo analyze the relationship of anxiety state with CD4(+) level and CD4(+)/CD8(+) ratio and to observe the effect of Chinese medicine (CM) treatment on anxiety in chronic hepatitis B (CHB) patients.

METHODSThe anxiety state of 120 CHB patients was evaluated based on Hamilton Anxiety Scale (HAMA) scoring. According to the scores, 63 patients with scores ≥14 were classified to anxiety and 57 patients with scores <14 to non-anxiety. The differences in CD4(+) cells and CD4(+)/CD8(+) ratio between patients with anxiety and non-anxiety were analyzed. Moreover, 63 patients with anxiety were randomized into two groups: 31 in the control group were treated with lamivudine (100 mg per day) alone and 32 in the observation group were given equal dosage lamivudine combined with CM treatment depending on syndrome differentiation, all for 12 weeks. The effects of treatment on anxiety state and T-lymphocyte subsets as well as its impact on some CHB-related indices were observed and compared.

RESULTSThe anxiety state of CHB patients was negatively correlated with CD4(+) and CD4(+)/CD8(+); the level of CD4(+) in patients with anxiety was significantly lower than that in non-anxiety patients (P<0.01 or P<0.05). After treatment, anxiety state in the observation group was significantly improved, with their HAMA scores significantly lowered (P<0.01), and the levels of CD4(+) and CD4(+)/CD8(+) were significantly higher than those in the control group (P<0.05 or P<0.01). Moreover, the alanine transaminase recovery rate and the HBV-DNA-negative conversion rate in the observation group were significantly higher than those in the control group, respectively (P<0.05).

CONCLUSIONSThe anxiety state of CHB patients was related to CD4(+) and CD4(+)/CD8(+) levels. CM treatment could improve the anxiety state and showed certain regulatory effect on the patients' immune system.

OBJECTIVETo investigate the estrogen-like activities of icariin (ICA), icaritin (ICT) and desmethylicaritin (DICT) and their structure/activity relationships.

METHODSICT was hydrolyzed from ICA by cellulase and then DICT was demethylated from ICT in boron tribromide and dichloromethane system. Estrogen-sensitive MCF-7 cells and T47D cells were co-incubated with different concentrations of test compounds for 6 and 9 d respectively, and the cell proliferation was measured by MTT.

RESULTSICT and DICT both markedly enhanced cell proliferation. Compared with estradiol (10.(-9) mol/L), the proliferative effects of 10.-6 mol/L ICT and DICT on MCF-7 cells were 90.0% and 94.0% (P<0.01), respectively, and those of T47D cells were 65.6% and 50.0%. (P<0.01). But this phenomenon was not observed with ICA. Cell proliferation induced by ICT and DICT was completely antagonized by 10.(-7 )mol/L pure estrogen receptor antagonist, ICI182,780.

CONCLUSIONICT and DICT possess estrogen-like activity of enhancing proliferation in MCF-7 and T47D cells. However, ICA appears to have no estrogenicity on MCF-7 and T47D cell lines in vitro.

To evaluate the efficacy and safety of acupuncture combined with traction therapy for lumbar disc herniation, providing the basis for future research strategies. Randomized control trials. (RCT) of acupuncture combined with traction therapy for lumber disc herniation at home and abroad from 2000 to 2013 were searched, analysis and evaluation of literature and strength of evidence were based on the principles and methods of Evidence-based Medicine. The total effective rate and curative rate were considered as primary outcome measures; pain improvement, quality of life, relapse rate and adverse effects were considered as secondary outcome measures. Seventeen RCTs were identified, Meta-analysis showed that (1) total effective rate and curative rate: acupuncture combined with traction therapy was better than single therapy (acupuncture or traction); (2) pain improvement: acupuncture combined with traction therapy was better than traction therapy; (3) relapse rate: current evidence could not support the conclusion that acupuncture combined with traction therapy was better than traction therapy. Acupuncture combined with traction therapy for lumbar disc herniation was effective. However, the included studies were with high risk of bias, important outcome measures such as quality of life, relapse rate and adverse effects were not found in most of the studies. Current evidence has not yet been able to fully reflect acupuncture combined with traction therapy for lumbar disc herniation is better than single therapy, so more RCTs of higher quality are needed to further confirm its efficacy and safety.

During the washing process of coarse bear gall powder extracts, it is necessary to adjust the amount of ethyl acetate according to the properties of raw materials, which aims to improving the yield and purity of the final product. In the research, using NIR spectra to reflect the comprehensive properties of coarse bear gall powder extracts, the process is optimized in a flexible way. Forty batches experiments are designed according to the weight ratio of ethyl acetate and coarse extracts of bear gall powder. The NIR spectra of the coarse extracts of bear gall powder are collected and processed using principal component analysis (PCA) method. The first 8 principal components combined with the amount of the ethyl acetate are used as the input variables, and calibration models are established to predict the yield and purity of the final product 30 batches are used as calibration set, which is used to establish the models, and other 10 batches are used as validation set, which is used for the performance appraisal of the established models. The correlation coefficients of the calibration, inner cross-validation and external validation for the purity model are 0.902, 0.896 and 0.883, respectively, and the RMSEC, RMSECV and RMSEP are 1.22%, 1.48% and 1.59%, respectively. The correlation coefficients of the calibration, inner cross-validation and external validation for the yield model are 0.921, 0.859 and 0.916, respectively, and the RMSEC, RMSECV and RMSEP are 1.39%, 1.65% and 1.53% respectively. This work demonstrated that NIR spectra combined with technology parameter could be used to predict the yield and purity of the final product. Using the established models, the most appropriate amount of the ethyl acetate can be determined according to the properties of the coarse bear gall powder extracts, and the yield and purity of the final product can be improved.
