ObjectiveTo study the clinical effect of locking compression plate fixation in treatment of the elders with unstable fractures of the distal radius. Methods17 cases with unstable distal radius fractures were treated by volar locking compression plate. The function of the carpal joints and the bone healing conditions were evaluated after operations. ResultsAll cases were followed-up for 7 to 16 months ( mean 12. 6 months). Union was obtained in all the patients after 11.4 weeks. The clinical outcomes were evaluated according to modified X-rays and wrist assessment. 12 cases were graded as excellent and 4 as good. 1 case were graded as poor. The overall satisfactory rate was 94. 1％. ConclusionThe unstable distal radial fractures could be effectively treated with open reduction and LCP fixation through volar approach.

Objective To investigate the effects of down-regulation of Netrin-1 expression on cell proliferation,apoptosis and migration of a cutaneous squamous cell carcinoma(CSCC)cell line SCL-1.Methods Unspecific(control)small interference RNA(siRNA)and Netrin-1-targeting siRNA were designed and constructed.SCL-1 cells were divided into 3 groups to remain untreated(control group 1),be transfected with control siRNA(control group 2)and Netrin-l-targeting siRNA(experiment group)by using Lipofectamine 2000 respectively.After 48 hours of additional culture,flow cytometry was performed to detect the apoptosis of cells,Western blot to determine the protein expression of caspase-3 and-9,Netrin-1 and matrix metalloproteinases (MMP)in these cells,and Boyden chamber was utilized to evaluate the migration of cells.Enzyme linked immunosorbent assay(ELISA)was performed with cholecystokinin-8(CCK-8)kit to estimate the proliferation of cells at 24,48,72 and 96 hours after the transfection.Results The expression of Netrin-1 protein was significantly downregulated in SCL-1 cells in the experiment group compared with the control group 1 and 2 (0.207 ± 0.044 vs.0.741 ± 0.111 and 0.716 ± 0.109,F =31.43,P ＜ 0.05).The Netrin-1-targeting siRNA significantly downregulated the proliferation of SCL-1 cells,but induced the apoptosis in SCL-1 cells with significant differences in the percentage of early apoptotic cells and late apoptotic cells between the control group 1,2 and experiment group(11.74 ± 0.33 vs.11.55 ± 1.22 vs.24.74 ± 2.43,F=68.63,P＜ 0.01;3.82 ± 0.32 vs.4.69 ± 0.68 vs.5.33 ± 0.18,F =8.58,P ＜ 0.05).The experiment group showed a significant increase in the expression of caspase-3 and-9(1.458 ± 0.111 vs.0.398 ± 0.057 and 0.412 ± 0.049,F =183.99,P ＜ 0.01;0.967 ± 0.099 vs.0.234 ± 0.036 and 0.205 ± 0.033,F =138.11,P ＜ 0.01),but a statistical decrease in the expression of MMP-2(0.235 ± 0.038 vs.0.862 ± 0.040 and 0.892 ± 0.035,F =291.07,P ＜ 0.01)compared with the control group 1 and 2.Conclusions The down-regulation of Netrin-1 expression can suppress the proliferation and migration of SCL-1 cells,but promote the apoptosis in SCL-1 cells.

Objective To deduce the interactions between genes from time series microarray data.Methods We used inter-transaction association rules mining technique and GO (Gene Ontology) annotation to analyze the microarray data. Results Using 2-fold-change method, 119 differential expression genes were identified from total 10 080 genes or ESTs, whose expression levels varied significantly on 6 periods of fetus cerebellar development. As a result, about 1 300 inter-transaction association rules were extracted and 10 top rules were kept for their maximum J-measure values. A genes association network graph was deduced based on the 10 top rules. Conclusion Inter-transaction association rules are able to deduce the interactions between genes from time series microarray data and the gene expression status can be predicted based on the association rules.

Objective To explore the role of clinical pharmacists in nutrition support therapy in the patients with hyperemesis gravidarum. Methods The clinical pharmacist played a positive role in nutrition support care of a patient with hyperemesis gravidarum by analysising disease characteristics and adverse drug reactions, providing suggestion on the selection of fat emulsion and offering an individualized pharmaceutical care. Results The clinical pharmacist recognized the potential risk in nutrition support plan, took modifications timely, and prevented the occurrence of unfavorable clinical outcomes. Conclusion The participation of clinical pharmacists in nutrition support therapy of the patients with hyperemesis gravidarum is beneficial to improve the efficacy and safety of nutrition support and promote the rational use of drugs.

0.05). Conclusions Our study does not support a positive association between Chlamydia pneumoniae infection or reinfection and MS. Chlamydia pneumoniae may be a bystander pathogen.

ObjectiveTo evaluate the value of application of spiral CT with 3D reconstructure on diagnosis and treatment of tibial plateau fractures.Methods15 cases of tibial fractures treated with x-ray and 16-slices spiral CT,3 D images were made,fractures were classified and evaluated with 3D images and treated with correct treatment.ResultsAll of the 15 patients got correct diagnosis by 16-slices spiral CT with 3D reconstructure,1 failed by x-ray.10 fractures were operated under 3D reconstructure guide and operation proved fractures revealed by 3D reconstructure finally.ConclusionSpiral CT with 3D reconstructure could offer more accurate location and classification of tibial plateau fractures,and it had obvious advantage on demonstration of spatial relationship,and it also could provide better planning and management for the tibial plateau fractures.

AIM: To study and analyze the clinical efficacy of diclofenac sodium eye drops combined with sodium hyaluronate eye drops in treating dry eyes after ophthalmic surgery.METHODS: Totally 94 eyes from 94 patients with dry eyes were slected, and they were randomly divided into orbervation group and control group.Fouty-seven patients in the control group using conventional treatment combined with sodium hyaluronate eye drops.Other 47 patients in orbervation group were treated with diclofenac sodium eye drops on the basis of control group.We compared symptoms, fluorescein station, tear film break time, Schirmer Ⅰ test between the two groups.RESULTS: Compared with before treatment, patients of both groups with sympotom, fluorescein station score, BUT, and Schirmer Ⅰ test were significantly improved(P<0.05).At the same time, sympotom, fluorescein station score, BUT and Schirmer Ⅰ test of control group were better than observation group(P<0.05).The cure rates of the orbervation group (98%) were more significant than control group (74%)(P<0.05).CONCLUSION: Diclofenac sodium eye drops combined with sodium hyaluronate eye drops have significant efficacy in treatment of dry eyes after ophthalmic surgery, which can effectively relieve clinical symptoms, improve BUT and Schirmer Ⅰ test.

Objective To investigate the expression and clinical significance of p27 protein in stage Ⅱ colon cancer.Methods The expression of p27 protein in 57 samples of stage Ⅱ colon cancer tissue from BeijingCancer Hospital was detected by immunohistochemistry and tissue microarray technique.Survival was analyzed by the Kaplan-Meier method,and the correlation between the expression of p27 protein and the prognosis of patients was analyzed by Pearson chi-square test.Multivariate analysis was done by using Cox proportional hazard regression model.Results The rate of high expression of p27 protein in stage Ⅱ colon cancer was 60%(34/57).The differentiation.location and distal metastasis of the tumor were correlated with the expression of p27 protein(X2=5.97,5.93,5.05,P＜0.05);while age,tumor size,growth patterns of tumor were not correlated with the expression of p27 protein(X2=0.64,0.49,0.33,P＞0.05).The 5-year survival rate of the patients with high expression of p27 protein was 94%(32/34),which was significantly higher than the 78%(18/23)of the patients with low expression of p27 protein(X2=3.86,P＜0.05).Multivariate analysis showed that low expression of p27 protein and tumor penetrating serous membrane are the independent adverse prognostic factors for stage Ⅱ coloR cancer.Conclusions Low expression of p27 protein is one of the independent adverse prognostic factors for stage Ⅱ colon cancer,and the expression of p27 protein should be consulted when screening out the patients who are in the high risk group of stage Ⅱ colon cancer.
