Objective To evaluate the effect of comfortable nursing intervention on the stress response of the elderly female patients with thyroid surgery in preoperative period. Methods From January 2010 to February 2014 ,109 elderly female thyroid disease patients with thyroid surgery were divided into two groups according to nursing types ,53 cases of routine nursing group and 56 cases of comfortable nursing group. Results The blood pressure and heart rate in two groups had no significant differences after operation(P>0.05). Respiratory rate had no significant differences in two groups before and after operation(P>0.05). Compared with the routine nursing group,blood pressure and heart rate sig-nificantly decreased,postoperative pain was significantly relieved on the first day after operation and the satisfaction rate was higher in the comfortable nursing group (P<0.05 or P<0.01).Conclusion Comfortable nursing can obviously de crease the stress response of elderly female patients with thyroid surgery in preoperative period by providing both men-tal and physical security for the patients.

Objective To analysis the MRI features of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), to improve the understanding of MRI manifestations of this disease. Meth?ods The clinical manifestations, neuroimaging analysis and genetic analysis were performed in the CADASIL pedigree proband and his families. Results Five of six cases were confirmed with C2182T mutation on exon 14 of the NOTCH3, of which three cases were diagnosed by MRI. Brain MRI findings included bilateral symmetric distributed confluent lesions in the subcortical and periventricular white matter in the frontal lobe, hypointensity on T1WI and hyperintensity on both T2WI and T2 FLAIR imaging in four cases. The external capsule was involved in three cases, with hyperintensity on T2WI. Subcortical lacunar lesions (SLLs) were shown in three cases. Lacunar infarction in the basal ganglia and thalamus were presented in four cases. T2WI hyperintensity at the brain stem was found in two cases. Cerebral microbleeds were re?vealed in three cases. There was no O’Sullivan sign in all the six cases. Conclusions There is characteristic change of MRI in CADASIL patients, which may play a very important role in screening these cases.

Objective To investigate the plasma vitamin D3 level and its association with B cell subsets of patients with primary Sj(o)gren's syndrome (pSS).The role of vitamin D3 levels in the pathogenesis of pSS was explored.Methods The expression of plasma vitamin D3 levels of 55 patients with pSS and 32 controls were analyzed by ELISA.Frequencies of peripheral blood CD19+CD27-na(i)ve B cells,CD19+CD27+ memory B cells and CD19+CD27high plasma cells were analyzed by flow cytometry in 34 pSS patients without therapy and 22 controls.The relationship between the vitamin D3 levels and B cell subsets,SSDAI,tear flow rate,saliva flow rate,rheumatoid factor,immunoglobulin was analyzed in pSS patients.Non-parametric test,t test,one-way ANOVA,x2test,Pearman's and Spearman's correlation analysis were used for statistical analysis.Results ① There was significant difference in the levels of plasma 1,25 (OH)2D3 between the pSS patients group and normal control group,1,25 (OH)2D3 was significantly lower in pSS patients than that in the normal control group [24.17(22.20,28.41) pg/ml and 41.25(23.38,62.18) pg/ml,P＜0.05],and that was also obviously lower in the active group [22.64(20.74,24.90) pg/ml] than that in the normal control group (P＜0.05),and that was also obviously lower in the active disease group than that in the inactive disease group [25.39 (23.16,33.09) pg/ml,P＜0.05],but there was no difference between the inactive group and the normal control group (P＞0.05).② The percentage of peripheral blood of CD19+CD27high plasma cells and CD19+CD27+ memory B cells in CD19+ cells was reduced in patients in the pSS group compared with the control group [(0.89±0.30)％ and (1.72±0.43)％,(24±8)％ and (34±5)％; P＜0.05],and that was also significantly lower in the active group [(1.03±0.59) ％ ; (26± 10)％] and inactive group [(1.00±0.16)％,(26± 3)％] than that in the normal controls (P＜0.05).However,there was no difference between the active group and the inactive group (P＞0.05),but the frequency of peripheral blood of CD19+ CD27-naive B cells in CD19+ B cells was increased in patients with pSS compared with normal control group [(75.4±7.5)％ and (63.9±5.2)％,P＜0.05],and that was also significantly higher in the active group [(73.4±9.7)％] and inactive group [(73.3±2.9)％] than that in the normal control (P＜0.05),there was no difference between the active group and the inactive group.③ Significant negative correlation was observed between 1,25 (OH)2D3 and the percentage of peripheral blood CD19+CD27+ memory B cells in CD19+ cells as well as immunoglobulin G(r=-0.627,P=0.039; r=-0.657,P＜0.01) level.Conclusions These results demonstrate that abnormality of vitamin D levels may play an important role in the pathogenesis of pSS.

Objective To explore the association of galactose-deifcient IgA1 levels with clinical features, and further to provide guidance for individualized treatment of HSP. Methods According to the clinical symptoms and curative effect, 57 children with HSP were divided into four groups:non-HSPN group (n=26), HSPN group (n=7), refractory HSP group (n=7) and remission group (n=17). In non-HSPN group, 12 cases received glucorticoid therapy and 14 cases did not. Serum galactose-de-ifcient IgA1 (Gd-IgA1) concentrations were detected using a Helix aspersa-lectin-based enzyme-linked immunosorbent assay (ELISA), and the total IgA1 levels were measured by ELISA. Results The serum Gd-IgA1 level was signiifcantly higher in 40 HSP children who were not cured than that in remission group and control group (P<0.05). However, there was no difference in Gd-IgA1 level between remission group and control group (P>0.05). Compared with the control group, the serum Gd-IgA1 level was signiifcantly higher in HSPN group, non-HSPN group and refractory HSP, and children with refractory HSP had signiifcantly higher Gd-IgA1 level than children in non-HSPN group (P<0.05). No signiifcant difference in Gd-IgA1 level was found either between HSPN group and refractory HSP group or between HSPN group and non-HSPN group (P>0.05). Furthermore, in non-HSPN group, the serum Gd-IgA1 level in HSP children who were not treated with glucorticoid was signiifcantly higher than that in HSP children treated with glucorticoid (P<0.05). Conclusions The serum Gd-IgA1 level is associated with the disease activ-ity and curative effect of HSP, especially in children with refractory HSP, and it is thus likely to be a new non-invasive disease activity marker for guiding the proper usage of glucocorticoid and immunosuppressants in HSP children.

ObjectiveTo explore the relationship between brain iron deposition and pathogenesis of tardive dyskinesia (TD) in schizophrenia.MethodsThe corrected phase (CP) of basal ganglia was measured in schizophrenia with TD( n=18) and without TD( n =18 ) using susceptibility weighted imaging MRI.Abnormal Involuntary Movement Scale (AIMS) was applied for clinical assessment of TD.ResultsAfter adjusting for age,sexual,and antipsychotic dosage,the mean CP of substantia nigra (SN) and caudate nucleus (CN) were significantly lower in schizophrenia patients with TD ( ( - 0.194 ± 0.040 ) rad,( - 0.089 ± 0.023 ) rad) than those without TD ( ( - 0.163 ± 0.033 ) rad,( - 0.076 ± 0.013 ) rad ; P =0.022,0.023 ).Lower mean CP in CN correlated with higher severity score of AIMS in TD patients ( r =- 0.468,P =0.034).Logistic regression analysis showed that the lower CP vaule in SN (β=-72.12,P=0.029) and CN(β=- 156.43,P=0.037),aging (β=0.379,P=0.042)were associated with the onset of TD.ConclusionThe results imply that the excess iron accumulation in basal ganglia may be associated with pathogenesis of TD in schizophrenia.
