Objective: To study the effect of tripterygium wilfordii polyglycosidium (TWP) on atopie dermatitis (AD) by detecting the expression of IL-2,IL-4,IFN-γ and IL-IO mRNA. Methods: RT-RCR was used to detect the mRNA of IL-2,IL-4, IFN-γ and IL-10 in peripheral blood mononuelear cells (PBMC)of AD cultured with different concentrations of TWP.ResuRs:(1)The expression of IL-2 was significantly different between the high concentration group and other groups(P<0.05 or P<0.01 ), and between the control group and the middle concentration group (P<0.01). (2)The expression of IL-4 was significantly different between the three different concentration groups (P<0.01 ). (3) The expression of IFN-γmRNA was significantly different between the high concentration group and the control, the low, the middle concentration groups (P<0.05 or P<0.01 ). (4)There was no significant difference in expression of IL-10 mRNA between the high concentration group and the middle concentration group (P>0.05), there was significant difference among the other groups (P<0.05 or P<0.01).Conclusion: TWP can suppress the expression of IL-2, IL-4, IFN-γand IL-10 mRNA, but the low concentration of TWP can suppress the high-level expression of IL-4 and IL-10mRNA in vitro.

Objective To evaluate the morbidity and the influence factors of the geriatric syndrome in the elderly inpatients. Methods The characteristics of comprehensive geriatric assessment of180 elderly inpatients (83 male and 97 female) with age older than 65 in geriatric department from November 2014 to November 2015 were analyzed. Results Of 180 elderly patients, the incidences of visual loss, multiple co-morbidity, polypharmacy, impairment in activities of daily living, urinary incontinence, chronic constipation and chronic pain were 86.11%(155/180), 85.56%(154/180), 82.78%(149/180), 56.11%(101/180), 49.44%(89/180), 46.67%(75/180) and 42.22%(76/180). Female patients had more incidences compared with male in urinary incontinence [56.70%(55/97) vs. 40.96%(34/83)], chronic pain [56.70% (55/97) vs. 25.30%(21/83)] , impairment in activities of daily living [64.95%(63/97) vs. 45.78%(38/83)] and high risk of falling [43.30%(42/97) vs. 21.69%(18/83)], and there were significant differences (P<0.05). In addition, it was found that with the increasing of age, the incidences of hearing loss and chronic constipation, as well as medications were accordingly higher. When the patients′education level was higher, the incidences of urinary incontinence and impairment in activities of daily living were generally declined. Compared with non-diabetes mellitus group, diabetes mellitus group had higher incidences of comorbidities, multiple co-morbidity, medications, polypharmacy and impairment in activities of daily living:(10.59 ± 3.72) kinds vs. (8.29 ± 4.03) kinds, 94.59%(105/111) vs. 71.01%(49/69), (10.07 ± 3.77) kinds vs. (6.87 ± 3.07) kinds, 89.19%(99/111) vs. 72.46%(50/69), 62.16%(69/111) vs. 46.38% (32/69). With the increasing of the numbers of diabetes- related chronic complications, the incidences of visual loss, chronic constipation and multiple co- morbidity, comorbidities and medications were higher (P<0.05). Conclusions Geriatric syndrome such as visual loss, multiple co- morbidity, polypharmacy, impairment in activities of daily living and urinary incontinence are very common in the elderly inpatients. Elderly patients with diabetes mellitus are much easier to suffer from geriatric syndrome such as multiple co-morbidity, polypharmacy and impairment in activities of daily living.

In this study, metabolism of nobiletin in rats was studied using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS). As a result, seven major metabolites were found in bile, urine and serum of rats. Three phase I products were assigned to be demethyl and di-demethyl products, and other four phase II products were assigned to be glucuronic and sulfonic conjugates. The four phase II metabolites were reported for the first time. Among the metabolites found in the present study, the glucuronic conjugates of demethyl-nobiletin played a predominant role in the metabolic pathway, indicating that its potential role for glucuronidation-related factors, such as gene polymorphism, drug-drug interaction, etc., in changing the active and toxic effect of nobiletin and that it should be paid more attention in further development.

Objective To compare effect of three therapies( modified constraint-induced movement therapy (mCIMT), constraint-induced movement therapy (CIMT) and Bobath therapies)on the recovery of motor function in upper-extremities of patients with apoplexy hemiparalysis. Methods Fifty-seven patients with apoplexy hemiparalysis were randomly divided into CIMT treatment group ( n = 19), mCIMT group (n = 19) and Bobath group (n = 19). Patients in Bobath group exercised 2 h/d, 5 d/week for 6 weeks. CIMT group and mCIMT group had restriction of movement at the unimpaired upper extremity by placing it in a sling a whole day for training using impaired extremity. Patients in CIMT treatment group exercised 6 h/d,5 days a week for 2 weeks in a row; mCIMT treatment group exercised for 1 h/d, 3 days a week, and also exercised in daily life at least 2 hours every day, for ten consecutive weeks. The patients in all three groups were assessed for upper-extremities motor function using FMA of Fugl-Meyer, for recovery of upperextremities motor speed using STEF and for recovery of daily ability at respective time-points of pre-treatment and the second week, sixth week and tenth week of post-treatment. Results In 3 assessments in the 3 groups there was no obvious change before treatment, while the FMA score was 45. 2 ± 5.1 (F = 1. 107 ,P =0. 382), BI score was 63. 1 ± 10. 3 ( F = 0. 930, P = 0. 401 ), STEF score was 63.4 ± 8.6 ( F = 1. 843, P =0. 168). At the second week, sixth week and tenth week of the treatment, the difference of assessment in the three groups was significant. The improvement in CIMT group was better after 2 weeks treatment compared with Bobath and mCIMT group, while the Bobath group showed better results than mCIMT group did after 6 weeks treatment. After 10 weeks treatment, the FMA, STEF in mCIMT and CIMT groups were improved better than Bobath group, while the BI score in mCIMT group was better than that in Bobath and CIMT group. Conclusions The mCIMT and CIMT therapy are better in improving the upper limb function in stroke patients compared with Bobath, while the mCIMT therapy is more effective in improving the abilities of daily life in stroke patients compared with the other two treatments.

Taxa-4(5),11(12)-diene is the precursor for paclitaxel biosynthesis. The diterpenoid paclitaxel (marketed as Taxol), a plant secondary metabolite isolated from yew, is an effective drug widely used in the treatment of numerous cancers. However, further application of taxol has been restricted due to its low yield in plants and the difficulties in extraction. To increase the intact isoprene flux, we constructed the fusion gene plasmid pBgGGTS and individual cassette plasmid pBgGGgTS to enhance the expression levels of geranylgeranyl diphosphate synthase gene (ggpps) and a taxadiene synthase gene (ts) in Coprinopsis cinerea. These two plasmids were separately transformed into C. cinerea LT2 strain, resulting in several putative transformants. Putative transformants were determined by PCR technique, indicating that 5 out of 13 putative transformants transformed by pBgGGTS and 6 out of 13 putative transformants transformed by pBgGGgTS, respectively. Additionally, the Southern blotting analysis of these 10 transformants confirmed that both ggpps and ts gene were stably integrated into the genome of C. cinerea. Crude extracts from each of the transformants were analyzed. There is no difference in the mycelium extracts among the wild-type LT2 and two types of transformants. However, analysis of culture filtrates indicated that an additional GC peak was found at the retention time of 16.762 min which was absent in the wild type control. The mass fragmentation pattern of this peak had the same diagnostic ions with taxa-4(5),11(12)-diene. According to peak area, the amounts of taxa-4(5),11(12)-diene in each fermented broth were 44 ng/L (transformed with pBgGGgTS) and 30 ng/L (transformed with pBgGGTS), respectively. In conclusion, co-expression of the ggpps and ts gene could increase the taxadiene production in C. cinerea.
