Background and purpose:Recently, a large number of researches have shown that cruciferous plants have the chemopreventive effect on tumor. Mechanisms of antitumorigenesis were investigated on antioxidation, antimutation, immunity and inducing apoptosis, and so on. Mustard seeds (MS) are the seeds belong to the cruciferous plants. This study aimed to investigate antioxidation and immune deviation of MS on colorectal tumor in rats induced by 1, 2-dimethylhydrazine (DMH). Methods:A total of 48 male Wistar rats were randomly divided into four groups:DMH alone, DMH+5%MS, DMH+7.5%MS, and the untreated control group(Saline). Colorectal tumorigenesis was induced by intraperitoneal injecting 30 mg/kg DMH once a week for 20 weeks. At the end of 32 weeks, the rats were sacrificed, then colorectal tumor incidence was observed and histological type was determined by HE staining. A colorimetric assay was used to detect levels of the lipid peroxidation product malondialdehyde (MDA) and the activity of antioxidant enzymes in the serum of all rats. The levels of Th1 and Th2 cytokines were detected with Luminex200. Results: No tumorous lesion was found in the untreated control group. However, the total tumor incidence in DMH+5%MS group and DMH+7.5%MS group was signiifcantly decreased 33.3%and 58.3%respectively, compared with the DMH group’s (100%, P<0.05). As DMH induced colorectal tumorigenesis, MDA and Th2 cytokines in the serum were signiifcantly higher in the DMH group than those in the untreated control group (P<0.05), but the activities of antioxidant enzymes were signiifcantly lower (P<0.05). While the MS treatment, compared with the DMH group, signiifcantly suppressed the MDA level but enhanced the activities of antioxidant enzymes and levels of Th1 cytokines (P<0.05). Conclusion: MS significantly decrease prevalence rates of DMH-induced colorectal tumor in rats. The mechanism may be related with the antioxidation and immune balance deviation.

Objective To investigate the influence of proprioceptive training of hemiplegic stroke patients on their visually compensatory dependence.Methods Twenty stroke patients without vestibular abnormalities were recruited.They were able to walk for 10 meters.All the patients underwent 4 weeks of rehabilitation training including proprioceptive training,treadmill exercises and isometric muscle strengthening.Static standing balance test was performed before and after 4 weeks of treatment.The parameters such as the anteroposterior and mediolateral sway of the center of gravity,center of gravity distribution were analyzed before and after the treatment,taking into consideration of visual feedback (eyes open or closed) by using t-test and multiple linear regression analysis.Results Visual feedback had significant no influence on the anteroposterior sway of center of gravity before and after training (P ＞ 0.05) ; Visual feedback had significant influence on mediolateral sway of center of gravity.Rehabilitation training significantly improved the mediolateral sway in opened-eye standing (P ＜ 0.05) but not closedeye standing (P ＞ 0.05).Visual feedback played significant role in center of gravity distribution after training (P ＜ 0.05).Conclusions Visual compensation is of significant influence on the mediolateral sway.Proprioceptive training can help decrease the patient's dependence on visual feedback and enhance the patient's balance ability.

AIM To investigate the effect of cisplatin on apoptosis in Scaber cell. METHODS The apoptotic cells were detected by TUNEL,HE,eletronic micrpscopy. RESULTS Treatment of Scaber cells with CDDP resulted in characteristics typical of apoptosis. CDDP induced apoptosis of Scaber cells in time and concentration dependent manner. To further investigate the mechanism of apoptosis induced by CDDP, the expressions and activity of apoptosis associated proteins such as bcl 2, bax and caspase 3 were examined using S P method.The results showed: CDDP caused time and concentration dependent decreases in bcl 2 and increased in bax proteins.CDDP bcl 2 and its translocation to perinuclei and nuclei. The expression of caspase 3 in Scaber cell were determined during apoptosis induced by CDDP. CONCLUSION Our investigetion showed that the apoptosis induced by CDDP is related to the increase of bax protein, and the decrease of bcl 2 protein. and its translocation to perinuclei and nuclei.

OBJECTIVE:To explore the method and efficacy of occlusion with medicinal albumin gel for esophageal fistula. METHODS:Over the recent 5 years,a total of 11 patients with esophagus -respiratory fistula or esophagus-neck fistula confirmed by iodine imaging and / or gastroscopy were occluded with medicinal albumin gel under endoscope. RESULTS:The occlusion with medicinal albumin gel for esophageal fistula was successful in all the 11 cases,and 9 out of 11 were completely healed after one time occlusion treatment and the other 2 cases were completely healed after the second occlusion treatment. The average hospital stay was 27 days and the average cost was 24,500 yuan. There was no recurrence after follow-up of 3 to 6 months,nor was there any adverse complication. CONCLUSION:Compared to the conventional conservative treatment,occlusion with medicinal albumin gel for esophageal fistula under endoscope can reduce the length of hospital stay and the cost of hospitalization.

Objective To investigate the relationship between the expression of Toll-like receptor 4 (TLR4) on mononuclear cells in peripheral blood and changes of serum vitamin D level in children with bronchiolitis.Methods The children who were diagnosed as bronchiolitis and received treatment in the Second Affiliated Hospital of Harbin Medical University from October 2013 to January 2014 were chosen as the pre-treatment group,and then divided them into moderate group and severe group according to the clinical symptoms,20 cases for each group.Then the cases in pre-treatment group who recovered after treatment were recruited as the after-treatment group,and the children who were healthy and medical examination in the Second Affiliated Hospital of Harbin Medical University in the same period were recruited as the healthy control group.The expressions of TLR4 on CD14 labeled mononuclear cells in the periphera were measured by flow cytometry.The level of 25 (OH) D in serum was detected by enzyme linked immunosorbent assay (ELISA).Results (1) The expression level in children with bronchiolitis of TLR4:the mode-rate group [(18.98 ±2.29)％] and severe group [(30.13 ±2.13)％] increased significantly (P ＜0.05) compared with control group [(1.17 ± 0.57) ％].And the expression level of moderate group [(2.02 ± 0.48) ％] and severe group [(11.43 ± 1.52) ％] decreased significantly after treatment (P ＜0.05).(2) Serum vitamin D level in children with bronchiolitis of the moderate group[(17.16 ± 3.34) μg/L] and severe group [(6.56 ± 2.28) μg/L] were lower than healthy control group [(53.69 ± 20.18) μg/L] before treatment (P ＜ 0.05),especially the severe group [(6.56 ±2.28) μg/L].The level of moderate group [(9.59 ± 2.31) μg/L] and severe group [(4.70 ± 0.67) μg/L] became lower after treatment (P ＜ 0.05).(3) Both severe group (r =-0.491,P ＜ 0.05) before treatment and moderate group (r =-0.436,P ＜ 0.05) after treatment showed negative correlation between TLR4 on mononuclear cells in peripheral blood and serum 25 (OH)D level in children with bronchiolitis.And no correlation was found among healthy control group,moderate group before treatment and severe group after treatment (P ＞ 0.05).Conclusions The conditions of children with bronchiolitis was positively correlated with the expression level of TLR4,and negatively correlated with the vitamin D level.The serum 25 (OH) D decreased steadily during the treatment.The expression of TLR4 in monocytes has a certain correlation with the level of vitamin D in children with bronchiolitis.

ObjectiveTo study the relationship between C-erbB-2 and estrogen (ER) and progesterone (PR) receptors, and the relationship between C-erbB-2, ER, PR with histologic grade. MethodsTo detect ER, PR and C-erbB-2 states by using immunohistochemical analysis and fluorescence in situ hybridization for C-erbB-2 in 163 unselected invasive breast carcinomas. ResultsC-erbB-2, ER ,PR were expressed in 21.5％ ,64.4％ ,44.2％ of 163 cases respectivly . 5 pure mucinous carcinomas , 3 tubular carcinomas and 1 micropapillary carcinoma were ER + ( 100.0％ ) 、C-erbB-2 - ( 100.0％ ) and PR + (40.0％ ,66.7％, 100.0％ ). C-erbB-2 was positive in 22.3％ of grade Ⅱ and 27.0％ of grade Ⅲ invasive ductal carcinomas and negative in all grade Ⅰ invasive ductal carcinomas.ER and PR expression were decreased significantly in C-erbB-2 + tumors compared with C-erbB-2 - tumors( ER,25. 7％ vs 75.0％ ; PR,25.7％ vs 49.2％ ). Although ER or PR expression is decreased in C-erbB-2 + tumors, a substantial proportion of them still express ER or PR. ConclusionC-erbB-2 overexpression or amplifcation was limited to a minority of invasive breast carcinomas. Tumour grade was an independent predictor for ER expression. ER was expressed in small number of high-grade and in large number of grade Ⅰ invasive ductal carcinomas. C-erbB-2 overexpression or amplification essentially was limited to grades Ⅱ and Ⅲ ductal carcinomas and correlated inversely with ER or PR expression.

A simple and convenient procedure for stereoselective synthesis of (Z)-allyl selenides has been developed by a one-pot reaction of diselenides with Baylis-Hillman adducts in the presence of samarium metal-trimethylsilyl chloride under mild conditions. Presumably, the diselenides are cleaved by Sm/TMSCl system to form selenide anions, which then undergo S(N)2' substitution of Baylis-Hillman adducts to produce the (Z)-allyl selenides.
