Effect of electroacupuncture on serum melatonin and dopamine in aged insomnia / 中国针灸

OBJECTIVE@#To observe the clinical effect of electroacupuncture (EA) on aged insomnia, and explore its possible mechanism.@*METHODS@#A total of 60 patients with aged insomnia were randomly divided into an EA group (30 cases) and a sham EA group (30 cases, 1 case dropped off). The patients in the EA group were treated with acupuncture at Baihui (GV 20), Yintang (GV 29), Shenmen (HT 7), Sanyinjiao (SP 6), Xinshu (BL 15) and Shenshu (BL 23), and EA was used at Baihui (GV 20) and Yintang (GV 29), with intermittent wave, 2 Hz in frequency. In the sham EA group, the acupoints and the EA connection acupoints were the same as those in the EA group, 2-3 mm in depth, but no current was connected. The intervention was given 30 min each time, once every other day, 3 times a week for 4 weeks in the both groups. Before and after treatment, the Pittsburgh sleep quality index (PSQI) and Montreal cognitive assessment (MoCA) scale were used to assess sleep quality and cognitive function, and serum melatonin (MT) and dopamine (DA) levels were detected.@*RESULTS@#After treatment, the total score and sub-item scores of PSQI in the EA group were lower than those before treatment (@*CONCLUSION@#Electroacupuncture can improve sleep quality and cognitive function in aged insomnia patients, and its mechanism may be related to regulating serum MT and DA levels.

Besides electroacupuncture (EA) applied to Baihui (GV 20) and Yintang (GV 29) in all of the three groups, acupuncture was added at Shenmai (BL 62) and Zhaohai (KI 6), Shenmen (HT 7) and Sanyinjiao (SP 6) as well as back-@*RESULTS@#After treatment, the score of each of 6 factors, named sleep quality, sleep latency, sleep time, sleep efficiency, sleep disturbance and daytime dysfunction, as well as the total score of PSQI scale were all reduced as compared with the scores before treatment in the patients of each group (@*CONCLUSION@#All of the three acupuncture combinations, named

Expression and Clinical Prognostical Significance of RIP2 in Diffuse Large B Cell Lymphoma / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To investigate the expression and prognosis significance of receptor interacting protein 2 (RIP2) in diffuse large B-cell lymphoma (DLBCL).</p><p><b>METHODS</b>The expression of RIP2 in DLBCL GCB and non-GCB type was detected by immunohistochemistry, at same time the expressions of BCL-2 and C-MYC were detected. Then, the role of RIP2 in development of DLBCL was analyzed by related clinical and pathological parameters.</p><p><b>RESULTS</b>The expression of RIP2 was related with middle-high risk group by IPI score, the An Arbor stage III+IV and intranodal lesions, and the differences were statistically significant (P<0.05). Besides, the single factor survival analysis suggested that GCB-type DLBCL showed a higher survival rate than that in non-GCB type(P<0.05). Patients with RIP2showed a lower survival rate as compared with patients with PIP2(P<0.05), among which the patients receiving R-CHOP had a higher survival rate than that of those receiving CHOP (P<0.01). The expression of RIP2 in DLBCL cell lines was higher than that in peripheral mononuclear cells of normal subjects (P<0.01) and expressed differently in DLBCL of GCB and non-GCB type (P<0.01).</p><p><b>CONCLUSION</b>The expression of RIP2 may relate with the poor prognosis and specific subtype of DLBCL.</p>

Expression and relationship of Ezh2, Runx3 and caspase-3 in endometrial adenocarcinoma / 中华病理学杂志

<p><b>OBJECTIVE</b>To investigate the role of the expression of Ezh2, Runx3 and caspase-3 proteins and their correlation in the pathogenesis of endometrial carcinoma.</p><p><b>METHODS</b>Expression of Ezh2, Runx3 and caspase-3 proteins was examined by tissue microarray technique and immunohistochemistry (SP method) in 72 cases of endometrial adenocarcinomas, 60 endometrial hyperplasia and 30 normal endometrial tissues.</p><p><b>RESULTS</b>The positive expression rates of Ezh2, Runx3 and caspase-3 proteins in endometrial adenocarcinomas were 83.3% (60/72), 26.4% (19/72) and 33.3% (24/72), respectively. The positive rate of Ezh2 protein in endometrial carcinomas was higher than that in normal endometrium and endometrial hyperplasia (16.7%, 33.3%, 63.3%;P < 0.05). However, the positive rate of Runx3 in endometrial carcinomas was lower than that in normal endometrium and endometrial hyperplasia (80.0%, 56.7%; P < 0.01). The positive rate of caspase-3 protein in endometrial carcinomas was lower than that in normal endometrium and endometrial hyperplasia (86.7%, 73.3%, 63.3%; P < 0.01). Positive expression of Ezh2 and Runx3 was related to the histological grade, FIGO stage, and depth of invasion of endometrial adenocarcinomas (P < 0.05), but it was not related to the lymph node metastasis (P > 0.05). Positive expression of caspase-3 protein was related to the histological grade (P < 0.05), but it was not related to the FIGO stage, depth of invasion and the lymph node metastasis of endometrial adenocarcinomas (P > 0.05). The expression of Ezh2 protein was negatively correlated to that of Runx3 (r(s) = -0.262, P < 0.05).</p><p><b>CONCLUSIONS</b>Abnormal expression of Ezh2, Runx3 and caspase-3 proteins is associated with the development and progression of endometrioid adenocarcinoma. Combined analysis of Ezh2, Runx3 and caspase-3 may offer prognostic information for patients with endometrial cancer.</p>

Effects of 1,25-dihydroxyvitamin D_3 on regulatory T cells and airway inflammation in asthmatic rats / 上海第二医科大学学报

Objective To investigate the effects of 1,25-dihydroxyvitamin D3[1,25(OH)2D3] on regulatory T cells(CD4+CD25+ Foxp3+ T cell)and airway inflammation in asthmatic rats. Methods Asthmatic models were established in 28 rats with ovalbumin as sensitinogen,and four groups were randomly divided(n=7).1,25(OH)2D3 was orally administered 1 h before challenge in treatment group 1,dexamethasone was subcutaneously injected 1 h before challenge in treatment group 2,both 1,25(OH)2D3 and dexamethasone were given 1 h before challenge in treatment group 3,while no medicine was administered 1 h before challenge in group 4(asthmatic control group).The levels of IL-4 and IL-10 in bronchoalveolar lavage fluid(BALF) were detected,the total cell numbers were obtained and the eosinophil count was performed.The ratios of Treg to CD4+ T cells in peripheral blood and spleen mononuclear cells were measured with flow cytometry,and the mRNA expression of IL-10 and Foxp3 in lung tissues was detected.Wistar rats without asthma were served as normal controls(n=7). Results There were significant differences between asthmatic control group and normal control group in each parameter.Compared with asthmatic control group,the total cell number and eosinophil count decreased,the level of IL-4 decreased and the level of IL-10 increased in BALF in treatment groups.The ratios of Treg to CD4+ T cells in peripheral blood and spleen mononuclear cells significantly increased,and the mRNA expression of IL-10 and Foxp3 in lung tissues increased in treatment groups compared with asthmatic control group.There was no significant difference between treatment groups and normal control group in each parameter. Conclusion Administration of 1,25(OH)2D3 increases the proportion of Treg and expression of Foxp3 mRNA in peripheral blood and spleen in asthmatic rats.1,25(OH)2D3 has a regulatory effect on Treg,and may serve as a potential therapeutic approach against asthma.
