Abstract：

Objective To detect the serum level of interleukin (IL)-1 1, lymphocyte subsets and NK cells in patients with idiopathic thrombocytopenic purpura (ITP), and explore the related factors in the pathogenesis of ITP. Methods The serum level of IL-11, lymphocyte subsets and NK cells were detected by double antibody sandwich enzyme linked immunosorbent assay (ELISA) and flow cytometry in 50 ITP patients (ITP group) and 30 controls (control group). Results The platelet in ITP group [ (30.21 ± 19.40) ×109/L] was lower than that in control group [ (207.21 ± 31.55 ) × 109/L] obviously (P ＜ 0.05 ); the serum level of IL-11 in ITP group [(255.72 ± 163.43) ng/L] was significantly higher than that in control group [ (40.60 ± 5.57 ) ng/L ] (P ＜ 0.05 ). The correlation analysis indicated that the blood serum levels of IL- 11 had negative relationship with the platelet (r = -0.557 ,P ＜ 0.05). The percentage of CD3+ and CD4+ T lymphocyte percentage, CD4+/CD8+ in ITP group were lower and the percentage of CD8+ T lymphocyte was higher than those in control group obviously (P ＜ 0.05 ). The percentage of CD3- CD(16+56) +NK cell in ITP group was lower than that in control group (P ＜ 0.05). Conclusion IL-11, lymphocyte subgroup and NK cell change correlate with ITP morbidity closely, and the IL-11 level and the platelet possibly have the negative feedback control action.

Abstract：

Objective To evaluate the effects of Taoist cognitive psychotherapy on depression of aged patients with cerebral stroke hemiplegia convalescence. Methods Seventy-seven hemiplegia convalescence patients with depression were divided into general treatment group (38 patients, received general back-up psychology therapy) and combined treatment group (39 patients, received general back-up psychology therapy and Taoist cognitive psychotherapy) by random digits table. All patients were treated for 8 weeks and followed up for 6 months. Two groups were evaluated with HAMD and SS-QOL before treatment and at the end of the 2 weeks,4 weeks, 8 weeks and 6 months after treatment. The results were analyzed with statistics. Results In general treatment group, the HAMD scores were gradually decreased, and the HAMD scores of patients after 8 weeks' treatment were significantly lower than those before treatment[(22.35 ± 4.69)scores vs. (29.62 ± 5.95 ) scores,t = 6.425 ,P ＜ 0.01]. At the end of 6 months after treatment, the scores increased [(24.48 ± 4.12 ) scores vs. (22.35 ± 4.69 ) scores, t = 2.014, P ＜ 0.05], but they were lower than those before treatment(t = 4.836, P ＜ 0.01 ). At the end of 6 months after treatment, the SS-QOL scores were lower than those after 8 weeks' treatment (t =2.543,P ＜0.05),but they were higher than those before treatment (t = 2.790,P ＜ 0.05 ). In combined treatment group, the HAMD scores decreased continuously,and the scores after 8 weeks' treatment [(20.08 ± 4.60) scores] and 6 months' treatment [( 15.21 ± 3.42)scores] were significantly lower than those before treatment [( 30.14 ± 4.92 ) scores] (t = 8.341,15.443, P ＜0.01). Meanwhile,the HAMD scores after 6 months'treatment were significantly Iower than those after 8 weeks' treatment (t =4.724,P ＜ 0.01 ). The SS-QOL scores after 8 weeks' treatment [( 117.56 ± 26.22)scores] and 6 months' treatment [(126.57 ±21.82) scores] were significantly higher than those before treatment[(86.54 ± 23.90) scores] (t = 6.716,8.916,P ＜ 0.01 ) ,and there was significantly difference(t=2.378,P ＜ 0.05). The HAMD scores of combined treatment group after 8 weeks' and 6 months' treatment were significantly lower than those of general treatment group at the same time(t = 2.118, P ＜ 0.05 ;t = 8.405,P＜ 0.01 ) ,and SS-QOL scores were significantly higher than those of general treatment group at the same time (t = 3.123,P ＜ 0.05 ;t = 6.580,P ＜ 0.01 ). Conclusions General back-up psychology therapy combined with Taoist cognitive psychotherapy can improve depression and life quality of cerebral stroke hemiplegia convalescence in aged patients. The effects of Taoist cognitive psychotherapy is slower, but it is more beneficial in the long time.

Objective To investigate the effects of ω-3 fatty acids (FA) on inflammatory reaction and immunologic function of patients after hepatectomy. Methods Totally 82 patients were randomized into control group and ω-3 FA group. Both groups received parenteral nutrition (PN) with equal nitrogen and calories. Patients in the control group received medium and long-chain lipid emulsion, and those in the ω-3 FA group received ω-3 FA combined with medium and long-chain lipid emulsion. Liver function test (serum total protein, prealbumin, albumin ,aspartate aminotransferase, alanine aminotransferase) , blood coagulation function (international normalized ratio) , immune globubin (IgA, IgG, and IgM) , CD3 and CD4/CD8 were measured on the first, third, and seventh post-operative day. Results Serum total protein in the ω-3 FA group [(61. 40 ±5. 12) g/L] was significantly higher than in the control group [(58. 54 ± 5. 53 ) g/L] (P = 0. 018 ) . Aspartate aminotransferase in the ω-3 FA group [(32. 37 ± 11. 92) U/L] was significantly lower than in the control group [(42. 50 ± 29. 97) U/L] (P = 0. 048). IgA in the ω-3 FA group [(2. 67 ± 1. 01) g/L] was significantly higher than in the control group [(2. 15 ±0.77) g/L] (P=0.027). IL-1β in the ω-3 FA group [(7.88 ±6.45) pg/ml] was significantly lower than in the control group [(12. 98 ± 11. 07) pg/ml] (P = 0.034). IL-2 in the ω-3 FA group [(24.98±20.38) pg/ml] was significantly lower than the control group [(43. 09 ± 20. 74) pg/ml] (P = 0.002). The white blood cell counts and coagulation function were not significantly different between two groups. Conclusion Total PN containing ω-3 FA can effectively improve immunologic function and liver function of patients after hepatectomy.
