Effect of warm joint needling plus rehabilitation on the balance function and quality of life of patients with spastic hemiplegia after ischemic cerebral stroke / 针灸推拿医学（英文版）

Objective:To observe the effect of warm joint needling plus rehabilitation techniques on the balance function and quality of life (QOL) of patients with spastic hemiplegia after ischemic cerebral stroke.Methods:Ninety patients with spastic hemiplegia after ischemic cerebral stroke were randomized into a rehabilitation group,a warm joint needling group and an observation group,with 30 cases in each group.The rehabilitation group was intervened by Bobath therapy,the warm joint needling group was treated with joint needling on the affected side plus warm needling,and the observation group was given the same rehabilitation treatment as the rehabilitation group together with the same warm joint needling as the warm joint needling group.The three groups were treated once another day,1 month as a treatment course for 6 months.Before the treatment,and respectively after 2-week,1-month,3-month,and 6-month treatment,the modified Ashworth scale (MAS) was used to measure the anti-spasm ability of the lower limb,the Berg balance scale (BBS) was adopted to evaluate the balance function,and the stroke-specific quality of life scale (SS-QOL)was employed to estimate the QOL.Results:After 3-month and 6-month treatment,the lower-limb MAS scores in the observation group were significantly better than those in the rehabilitation group and the warm joint needling group (all P＜0.05).After 1-month,3-month and 6-month treatment,the BBS scores in the observation group were significantly better than those in the rehabilitation group and the warm joint needling group (all P＜0.05).After 2-week,1-month,3-month and 6-month treatment,the SS-QOL scores in the observation group were markedly better than those in the rehabilitation group and the warm joint needling group (all P＜0.05).Conclusion:Warm joint needling plus rehabilitation can effectively improve the lower-limb spasticity state,balance function and QOL in patients with spastic hemiplegia after ischemic cerebral stroke.

Expression of proteasome immunosubunit in labial glands of patients with primary Sjogren's syndrome.

OBJECTIVE: To investigate the expression of proteasome immunosubunit low molecular weight polypeptide (LMP)2 and LMP7 in labial glands of patients with primary Sjogren's syndrome patients, and thus explore their role in the diagnosis, differential diagnosis and pathogenesis of primary Sjogren's syndrome (pSS). METHODS: Labial specimens were collected from 40 patients with pSS, 15 patients with connective tissue diseases other than pSS, and 9 healthy controls. The expressions of LMP2 and LMP7 in labial specimens were determined using immunohistochemical approaches and analyzed using semi-quantitative methods. The positive rate of acinar was calculated. After the square arcsine transformation of data, the differences of the positive rate in acinar between LMP2 and LMP7 were compared among three groups. Spearman's rank correlation coefficient was used for analyzing the correlation of clinical manifestations with LMP2 and LMP7 expressions. RESULTS: The expressions of LMP2 and LMP7 within the acinar and ductal epithelial cells were confirmed. Although the LMP2 expression in labial specimens was not significantly different among three groups(P=0.369), the expression of LMP7 was significantly higher in pSS patients compared with patients with connective tissue disease and healthy controls (P<0.01). Only in pSS group, LMP7 was found to be with higher positive rate in acinar than LMP2 (P<0.01). No significant correlation was found between LMP2/LMP7 and clinical manifestations (P>0.05). CONCLUSION: In patients with pSS, the expression of LMP7 (but not LMP2) is up-regulated in labial gland, indicating these two proteins have different genetic regulation mechanisms.

T-2 toxin-induced apoptosis involving Fas, p53, Bcl-xL, Bcl-2, Bax and caspase-3 signaling pathways in human chondrocytes / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

<p><b>OBJECTIVE</b>To investigate the effects of T-2 toxin on expressions of Fas, p53, Bcl-xL, Bcl-2, Bax and caspase-3 on human chondrocytes.</p><p><b>METHODS</b>Human chondrocytes were treated with T-2 toxin (1-20 ng/ml) for 5 d. Fas, p53 and other apoptosis-related proteins such as Bax, Bcl-2, Bcl-xL, caspase-3 were determined by Western blot analysis and their mRNA expressions were determined by reverse transcriptase-polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>Increases in Fas, p53 and the pro-apoptotic factor Bax protein and mRNA expressions and a decrease of the anti-apoptotic factor Bcl-xL were observed in a dose-dependent manner after exposures to 1-20 ng/ml T-2 toxin, while the expression of the anti-apoptotic factor Bcl-2 was unchanged. Meanwhile, T-2 toxin could also up-regulate the expressions of both pro-caspase-3 and caspase-3 in a dose-dependent manner.</p><p><b>CONCLUSION</b>These data suggest a possible underlying molecular mechanism for T-2 toxin to induce the apoptosis signaling pathway in human chondrocytes by regulation of apoptosis-related proteins.</p>

Protective effect of selenium against T-2 toxin-induced inhibition of chondrocyte aggrecan and collagen II synthesis / 南方医科大学学报

<p><b>OBJECTIVE</b>To study the inhibitory effect of T-2 toxin on the expression of aggrecan and collagen II in chondrocytes and the protection of selenium against this effect.</p><p><b>METHODS</b>Human chondrocytes cultured in vitro were treated with T-2 toxin at different concentrations for varied time periods (1-5 days), and the cell viability was measured by MTT assay. Aggrecan expression was detected by toluidine blue staining and collagen II expression by immunostaining using monoclonal antibody of collagen. Aggrecan and collagen II mRNA expressions were measured by semiquantitative RT-PCR.</p><p><b>RESULTS</b>T-2 toxin dose- and time-dependently affected chondrocyte viability within the concentration range of 0.001-2 mg/L, the prolonged treatment time further enhanced the dose dependence of the inhibitory effect. T-2 toxin lowered aggrecan and collagen II synthesis in the chondrocytes and reduced their mRNA expressions. Selenium could partly attenuate the inhibitory effects of T-2 toxin on aggrecan mRNA expression, but showed no such effect against T-2-induced collagen II expression.</p><p><b>CONCLUSION</b>T-2 toxin can obviously inhibit aggrecan and collagen II synthesis in human chondrocytes, and selenium can partly antagonize the inhibitory effects of T-2 toxin on aggrecan.</p>
