A total of 115 patients with Hoshimoto thyroiditis were classified under 2 groups: one group being treated with selenium and L-throxine (L-T4) and other group with L-T4 alone.All patients were followed up for 3 months.In the selenium treated group thyroid peroxidase antibody level was decreased in 33 patients (56%) and thyroglobulin antibody level was decreased in cases.

Objective To verify the effectiveness of electrical impedance tomography (EIT) with multi-layer electrodes in gastric emptying measurement by simulation experiments using EIT with three-layer electrodes.Methods Firstly,EIT system with three-layer electrodes and gastric emptying measurement simulation equipment was designed and constructed to simulate gastric emptying process and obtain EIT reconstruction images.Secondly,the region where the electrical characteristic of gastric changes was selected as region of interest.Finally,the relative impedance change rate in region of interest for every image obtained from all three layers was consecutively recorded,then the gastric emptying curve was formed and gastric emptying time was calculated.Results There are obvious differences among the sharp of impedance change curves of interested region for three layers,and the gastric emptying time and process of each layer is also different from one another.It is suggested that the passing path and emptying manner of food in gastric emptying process reflected by EIT images varied from layer to layer.Therefore,the necessity and feasibility of using EIT with three-layer electrodes in gastric emptying measurement study is verified.Conclusions EIT with three-layer electrodes can provide more abundant information of gastric motility function associated with gastric emptying pathology and physiology state.It is likely to be a noninvasive,convenient and effective imaging method for the detection and evaluation research on gastric emptying and gastric motility.

Eight-weeks old C57BL/6J male mice were treated with normal or high fat diet for4 weeks,and then bone mass,number and activity of osteoclasts,differentiation of osteoblasts from bone marrow mesenchymal cells and the change in lipid genes expression were studied.Compared with the normal diet treated group,bone mass of femur from high fat diet treated animal was decreased,but there were increased number and activity of osteoclasts and raised lipid genes expression levels.Besides,no obvious change was found in differentiation of osteoblasts from bone marrow mesenchymal cells.The loss of bone mass induced with high fat diet in young mice was mainly due to increased activity of osteoclasts and bone resorption.

Objective:To study the incidence, clinical features, diagnosis, and treatment of angioimmunoblastic T-cell Lymphoma (AITL). Methods:We retrospectively analyzed the clinical data of 31 patients with AITL treated in the tumor hospital of Harbin Medical University between January 1995 and January 2008. We also analyzed the incidence, clinical features, diagnosis, and treatment of AITL. Results:The complete response rate and partial response rate of the entire group were 54.8%and 16.1%, respectively. The overall response rate was 70.9%, and the median survival time was 27.3 months. The five-year survival rate of the entire group was 35%. The response rate was 76.5%in the CHOP group and 75%in the COP group. No significant differences were detected between two groups (P>0.05). Con-clusion:The symptoms and signs of ATIL differ in different sites. The COP and CHOP regimens have similar efficacy and tolerable side effects.

This study was aimed to analyze compatibility rules of Chinese drugs and prescription design in the pre-vention and treatment of scleroderma. The database of scleroderma treated by Chinese medicine was set up. And then, association rules were used to analyze the prescription compatibility rules. The results showed the highest fre-quency of drugs in the treatment of scleroderma were Astragalus, Angelica sinensis and Salvia. The tonifying and re-plenishing medicinal, blood-activating and stasis-resolving medicinal and exterior-releasing medicinal were with the highest frequency. The commonly used formula in the treatment of scleroderma was Y ang-He decoction. For herbal groups, occurrence of the highest was the combinations of Ramulus Cinnamomi-Astragalus and Carthamus tinctorius L.-Astragalus. Three kinds of herbals were commonly coupled, such as Polygonum multiflorum Thunb. and Caulis Spatholobi with Salvia, P. multiflorum Thunb. and R. Cinnamomi with Salvia, P. multiflorum Thunb. and Astragalus with Salvia, prepared Radix Rehmanniae and Codonopsis with C. tinctorius L., prepared Radix Rehmanniae and Codonopsis with R. Cinnamomi, Codonopsis and Radix paeoniae rubra with R. Cinnamomi. Four kinds of herbals such as R. Cinnamomi, Glycyrrhiza uralensis Fisch., Astragalus and Codonopsis were commonly coupled. It was con-cluded that compatibility rules of Chinese medicine in the prevention and treatment of scleroderma laid the founda-tion for herbal medicine selection and prescription design.

Objective To discuss the influence of team-based learning (TBL) on autonomous learning ability of undergraduate nursing students. Methods 160 undergraduate nursing students of Grade 2010 were randomly divided into experimental group and control group with 80 students in each group. Students in the experimental group were taught with TBL while students in the control group were taught with lecture-based learning (LBL). The score of autonomous learning ability was measured by scale of self-directed learning ability for nurses. Results Scores of autonomous learning ability in experimental group (120.33 ±16.09) was higher than that of control group (110.87 ±11.89) (P=0.000) and also higher than that of experimental group (100.35±11.15) before the implementation of TBL (P=0.000). The differences were statistically significant. Conclusion Team-based learning (TBL) can be helpful in improving the autonomous learning ability of undergraduate nursing students.

Objective To evaluate the vestibular function in patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Methods Seventeen CADASIL patients were recruited in the present study and 17 healthy volunteers served as control subjects. Electronystagmogram examinations including gaze nystagmus test, spontaneous nystagmus test, saccade test, pursuit test, optokinetic nystagmus test and caloric test were performed in the subjects. Results Neither patients nor controls had gaze nystagmus or spontaneous nystagmus. There was no difference in the latency and velocity of saccade movement between patients and controls. The accuracy of the saccade movement, the accuracy in leftward saccade, was significantly lower in CADASIL group compared with controls. The pursuit movement gains was also significantly lower in CADASIL group than in control group(G_L:0.79±0.08, G_R:0.76±0.12)(t=-3.739、-2.911,P <0.05) compared with controls(G_L:0.87±0.04, G_R:0.86±0.06).The optokinetic nystagmus gains were significantly decreased in CADASIL group(G_L:0.79±0.17,G_R:0.78±0.18)(t=-2.342、-2.335,P<0.05) compared with controls(G_L:0.90±0.08,G_R:0.89±0.09). The caloric test was performed in one CADASIL patient and the result revealed an incomplete fixing inhibition. CADASIL group was further divided into normal subgroup and abnormal subgroup based on the pursuit curve. The comparison between those two subgroups demonstrated a significant correlation between the pursuit movement and the symptoms of vertigo or dizziness(P<0.05). Conclusions The central vestibular function is impaired in CADASIL patients and the abnormal vestibular function is related to the symptom of vertigo or dizziness in CADASIL patients.
