: Insomnia is one of the most often complaints in the stroke patients and its incidence rate in the stroke patients is more higher than in general population.Insomnia can adversely affect the stroke patients' rehabilitation.Sedative hypnotics are still the most often used for insomnia after stroke currently.Furthermore,several studies have compared different pharmachotherapies and nonpharmachological treatments for insomnia after stroke.

Objective To analyze the factors contributing to local recurrence following body gamma knife radiotherapy in patients with non-small cell lung cancer(NSCLC),and to explore a standard therapeutic scheme under the circumstance.Methods 332 patients with NSCLC received body gamma knife therapy and subsequent regular follow-up.Dose per fraction and total dosage used were dependent on disease condition,tumor location,tumor features and tumor size,etc.On the basis of patients' conditions and adverse effects,biological effective dose(BED) was 56-90Gy calculated with LQ model.Univariate analyses were performed including sex,age,Karnofsky performance score,clinical stage,pathological type,tumor differentiation degree,tumor size,tumor location,target volume delineation,dose per fraction,BED and chemotherapy scheme,etc.with X2 or t test.By selecting significant clinical factors in univariate analysis,multivariate analyses were performed with COX regression model.Results Of the 332 patients,local recurrence occurred in 22 cases during regular follow-up period,with average recurrence time of 10 months,and the local recurrence rate was 6.63%.The results of multivariate analysis showed that low BED,low Karnofsky score,old age,too small delineation for target volume range and central type of lung cancer were the factors related to local recurrence.Conclusions Low BED in body gamma knife radiotherapy is the significant factor of local recurrence for patients with NSCLC.BED in body gamma knife radiotherapy should be more than 80Gy for NSCLC patients who receive the radical treatment.

Objective To evaluate the therapeutic effects and complications of whole body gamma knife conformal radiotherapy for patients with non-small cell lung cancer(NSCLC).Methods 169 patients with NSCLC received whole body gamma knife conformal radiotherapy.Total dose,fractions,and radiation time were determined based on disease course,tumor location,tumor features and tumor volume,etc.Small target volume(tumor size less than 3cm in diameter) received 5-10Gy each time,40-50Gy in 4-10 fractions;moderate target volume(tumor size 3cm-5cm in diameter) received 4-8Gy each time,48-56Gy in 4-16 fractions;and big target volume(tumor size more than 5cm in diameter) received 3-4Gy per time,40Gy in 10-14 fractions and followed by 10-30Gy using reduced fields.Results Of 269 tumors in 169 patients,complete response(CR) rate,partial response(PR) rate,and rate of no change(NC) were 41.6%(112/269),44.6%(120/269) and 13.8%(37/269),respectively.Overall response rate(CR+PR) was 86.2%(232/269),with 1-year local control rate of 92.3%.1-year and 2-year survival rate was 75.1% and 46.2%,respectively,with median survival time of 19 months.The incidence of Grade 1,2 and Grade 3 radiation pneumonia was 15.4% and 3.1%,respectively.Conclusions With minor adverse effects,whole body gamma knife conformal radiotherapy may have short-term therapeutic effects for NSCLC patients with amelioration of disease symptoms,obvious elevation of tumor local control rate,a raise of the survival rate,and improvement of life quality.

In this study ,we detected the positive rate of anti‐HBs and anti‐HBc antibody among the subject population in Fujian Medical University Union Hospital ,and to evaluate different detection methods of anti‐HBc antibody .The positive rate of anti‐HBs and anti‐HBc antibody were detected by chemiluminescent microparticle immunoassay (CMIA) and one‐step com‐petitive enzyme‐linked immunosorbent assay (ELISA) from the year 2012 to 2013 .The subject population was divided into three groups :group 1 with the age of less than 2 years old ,group 2 with the age of 2‐20 years old ,and group 3 with the age of more than 20 years old .The positive rates of anti‐HBV antibody in the different groups were analyzed .Furthermore ,anti‐HBc antibody of 92 samples selected from the immunized population was detected by CMIA and three kinds of ELISA reagents . Meanwhile ,the detection of anti‐HBc antibody by the same ELISA reagent but different operating modes were performed in these samples .The highest positive rate of anti‐HBs antibody was detected in group 1 ,and there was no significance difference of positive rate between two detection methods of anti‐HBs antibody among three groups .The positive rate of anti‐HBc anti‐body using CMIA was significantly lower than those with ELISA among group 1 and 2 .Among the 92 samples ,the positive rate of anti‐HBc antibody was 2 .2% using CMIA .With three kinds of method of ELISA reagent ,the positive rate of anti‐HBc antibody were 79 .3% ,82 .6% and 94 .6% ,respectively ,and there was no statistical significance among the results of three ELISA reagents .Anti‐HBc was not detected from 19 samples using ELISA methods with different operating modes .It's con‐cluded that the anti‐HBs antibody declined with the increase of age ,and it is necessary to discriminate the specific population to strengthen immune system .The obviously higher positive rate of anti‐HBc antibody was found by ELISA in immunized popula‐tion than that by CM IA . Concerning on the false positive of ELISA , specimen sampling with one specific test item or the CMIA method was recommended to detect the anti‐HBc antibody .

Objective To study the role of suppressor of cytokine signaling ( SOCS ) in the pathogenesis of primary biliary cirrhosis( PBC),the levels of SOCS protein and the changes of function of dendritic cell(DC) were respectively observed from PBC patients.MethodsThe study population consisted of 10 patients of PBC and 8 healthy controls.Phenotypic analysis of cultured peripheral blood mononuclear cells (PBMC)-derived DC was performed by flow cytometry (FCM),such as CD83,CD86 and human leukocyte antigen DR (HLA-DR).The levels of interleukin-10 (IL-10),interferon-γ( IFN-γ) and IL-12 in culture supematant of DC were measured by enzyme linked immunosorbent assay ( ELISA ).The protein levels of SOCS1 and SOCS3 were detected by Western blot ( WB ).The features of changes in these parameters were analyzed between the two groups.ResultsThe expression of CD83,CD86 and HLA-DR in PBC patients were ( 79.4 ± 4.8 ) ％,( 86.5 ± 6.3 ) ％ and (90.0 ± 3.5 ) ％,which were significantly higher than those in healthy control group[ (68.3 ±4.1 )％,(74.2 ±6.3)％ and (83.6 ±7.6)％ ],respectively (t =5.340,4.120,2.514,P ＜0.05).The levels of IL-12 and IFN-γin PBC patients were (53.5 ± 11.1)and (32.0 ±9.0) ng/L,which were significantly higher than those in healthy control group[ (32.1 ± 10.7) and (15.4 ± 8.1 ) ng/L; t =4.123,3.818,P ＜ 0.01 ].There were not any significant difference of IL-10 level between PBC patients [ (7.0 ± 4.6) ng/L ] and the healthy controls [ ( 5.8 ± 4.2) ng/L; t =0.563,P ＞ 0.05 ].The proteins levels of SOCS1 and SOCS3 in PBMC-derived DC from PBC group were decreased significantly than those in healthy control group.ConclusionsThe results suggest that the PBMC-derived DC in PBC patients has greater ability of potent maturation and antigen presentation function.The decreased expression of SOCS levels may be associated with the excessive immunological reaction and the breakdown of self-tolerance.

Objective To explore the relationship between quality life and TCM constitutions of elderly patients with hypertension in a community in Shanghai; To provide the basis for the suitable and feasible community elderly hypertension management method. Methods Through multistage stratified sampling method, 808 elderly patients with hypertension in the community were investigated for their life quality and TCM constitutions on the basis of inform consent and voluntary participation. The life quality and TCM constitution characteristics as well as the relationship were analyzed by applying the statistic analysis software. Results Among the investigated elderly patients with hypertension in the community, 97.28% cases’ overall life quality was above the middle level and 91.46% cases’ self-evaluated health and quality of life scores were above the middle level. 54.70% cases were gentleness type, and the biased constitution was dominated by qi deficiency, yang asthenia, yin asthenia and phlegmatic hygrosis. The relationship between life quality and TCM constitutions may be existent. If TCM constitutions tended to be gentleness type, the physical score and the psychological score would be higher, which leaded to better quality of life. Conclusion TCM constitution characteristics are associated with quality life of elderly hypertension patients in the community. Intervention targeted on the results of TCM constitution identification would be better to prevent and control hypertension and improve health level and quality of life.

Mechanical properties and biological evaluation of buffalo horn material were examined in this study. The effects of sampling position of buffalo horn on mechanical properties were investigated with uniaxial tension and micron indentation tests. Meanwhile, the variation of element contents in different parts of buffalo horn was determined with elemental analysis, and the microstructure of the horn was measured with scanning electron microscopy. In addition, biological evaluation of buffalo horn was studied with hemolytic test, erythrocyte morphology, platelet and erythrocyte count, and implantation into mouse. Results showed that the buffalo horn had good mechanical properties and mechanical characteristic values of it gradually increased along with the growth direction of the horn, which may be closely related to its microstructure and element content of C, N, and S in different parts of the buffalo horn. On the other hand, because the buffalo horn does not have toxicity, it therefore does not cause hemolysis of erythrocyte and has a good affinity with it. Buffalo horn has good histocompatibility but meanwhile it may induce the platelet adhesion and aggregation. Even so, it does not continue to rise to induce a large number of platelet to aggregate with resulting blood clotting. Therefore, the buffalo horn material has been proved to possess good blood compatibility according to the preliminary evaluation.
