BACKGROUND:Studies have found that the glass fiber splint which is embedded into the groove on the lingual surface of the affected tooth plus fluid resin fixation between the gap of mobile teeth can achieve more satisfactory clinical effects on the stabilization of loose front teeth.
OBJECTIVE:To observe the clinical effects of glass fiber splints prepared using two tooth preparation methods on splinting loose front teeth and their debonding rate through a 5-year fol ow-up visit.
METHODS:Ninety-four chronic periodontal disease patients, who had received periodontal treatment, were enrol ed in this study for their loose front teeth of degree II-III. Al the enrol ed patients were good candidates for periodontal splinting strictly in accordance with the indications for periodontal splinting. According to whether the fluid resin was used to seal the gap between the mobile teeth, the 96 patients were divided into two groups:patients undergoing glass fiber splint+fluid resin between the mobile teeth served as experimental group, and those only undergoing glass fiber splint as control group. Al the patients were fol owed by regular clinical referral or telephone fol ow-up for 5 year, to evaluate the fixed effects.
RESULTS AND CONCLUSION:During the 5 years of regular clinical referral or telephone fol ow-up, seven of the 76 cases and 12 of the 18 cases were found in the experimental and control groups, respectively, to have debonding between the abutment and the splint. Compared with the control group, the probing depth and attachment loss of affected teeth were improved significantly (P<0.05), and the percentage of alveolar bone height accounting for the root length increased significantly in the experimental group (P<0.05) after 5 years of fol ow-up. Patients in the experimental group felt comfortable without foreign body sensation. The results confirmed that the glass fiber splinting plus fluid resin fixation between the gap of mobile teeth was a better treatment for loose front teeth during the 5-year fol ow-up.

Background and purpose:The symptoms of pancreatic neuroendocrine neoplasms (PNENs) are complicated, that might lead to misdiagnosis. This study aimed to detect the expression level of DJ-1 in PNENs and explore the clinical significance of DJ-1 in PNENs.Methods:DJ-1 protien levels in the serum of 16 cases of PNENs patients and 25 cases of healthy persons were detected by ELISA analysis; The expressions of DJ-1 in 78 cases of PNENs tissues were detected by immunohistochemical staining.Results:The DJ-1 level in the serum of PNENs patients was signiifcantly higher than healthy persons (36.19±6.71vs 24.68±5.94 ng/mL;P<0.001);53.8% (42/78) cases of PNENs tissues showed DJ-1 positive staining; DJ-1 expression level in PNENs tissues had signiifcantly positive correlation with lymph node metastasis (P=0.033), distant metastasis (P=0.017), TNM stage (P=0.012), and pathology grade (P=0.049); As a dependent risk factor, DJ-1 expression was signiifcantly associated with shorter OS (P=0.003) and DFS (P=0.018) of PNENs patients.Conclusion:High expression of DJ-1 protein correlated with invasion and metastasis, disease progression, and poor prognosis in PNEN.

ObjectiveTo explore the influence of narcissism of mothers of middle school students on maternal consciousness and their rearing patterns,and to provide theoretical support for family education.Methods361 pairs middle school students and their mothers were sampled randomly and tested by middle school students' mother maternal consciousness scale and the narcissistic personality Inventory for the mothers,and the mother's subscale of EMBU for the students respectively.The data were analyzed by ANOVA,product-moment correlation and path analysis.Results 1 ) Overt narcissism had significant differences among different levels of income(F=6.501,P＜0.001 ); 2)overt narcissism was correlated positively with emotional warmth and understanding of mother and mother' s over-interference,over-protection ( r =0.121,0.126,P ＜ 0.05 ) ; covert narcissism was correlated negatively with maternal consciousness and emotional warmth and understanding of mother,and positively with over-protection,refusal and deny,and severe punishment; 3 )narcissism of mothers not only would influence their rearing patterns through maternal consciousness indirectly( β=0.319,P=0.000),but would influence that directly ( covert narcissism:β =0.281,P =0.000 ; overt narcissism:β =- 0.278,P =0.000) ; and overt narcissism had positive effect,while covert narcissism had negative effect.ConclusionNarcissism of mothers of middle school students influences maternal consciousness and rearing patterns,and effect of overt narcissism is positive,and that of covert narcissism is negative.So it is important to perfect mother's character for ameliorating their rearing pattern.

Objective: To investigate the effects and mechanism of transhinone on calcium overloaded injuried models.Methods: Three injured models induced by caffeine, KCI, and NMDA, respectively, were used to assay the action of tanshinone in cultured primary cortex neurone of baby rats. Results: It was found that tanshinone possessed obvious protective effects on primary neurone in injured models by the way of morphological examination. Crystal violet staining and lactic dehydrogenase (LDH) measurement in supernate also indicated that tanshinone increased number of live neurone and reduced the extent of cell injury significantly.Conclusion: Tanshinone protected rat cortex cells from three kinds of calcium overloadied injured effectively in vitro.

Objective To detect the changes of function of blood-aqueous barrier in different Syndrome stages of patients with Vogt-Koyanagi-Harada (VKH) syndrome in order to provide the appropriate therapy. Methods According to clinical manifestation, 77 patients (144 eyes) with VKH syndrome were divided into 4 groups: 10 cases in posterior uvietis stage group (20 eyes), 27 in anterior uveal involvement stage group (50 eyes), 23 in recurrent anterior uvitis stage group (41 eyes), and 17 in convalescent stage group (33 eyes). The other 50 cases (100 eyes) were in the control group. Flare and cells of anterior chamber in patient with VKH Syndrome at different stages were graded and measured by laser flare and cell meter (LFCM) and slitlamp microscope. Results According to the results of slitlamp biomicroscopy, anterior chamber flare and cells were at the 0 grade in the patients at posterior uvietis stage (20 eyes). The results of LFCM examination revealed that the flare value and cells were (9.7?3.4) pc/ms and (0.9?0.6)/0.5 mm3 in posterior uvietis stage group, and (5.3?2.3) pc/ms and (0.8? 0.6)/0.5 mm3 in the control group. The differences between the two groups were significant (P

Objective To investigate effect of double end-to-side neuroanastomosis for bilateral obsolete proper digital nerve injuries.Methods From November 2000 to October 2009,40 patients with bilateral obsolete proper digital nerve injuries were admitted to our center.Fifteen patients underwent double end-to-side neuroanastomosis.During operation,the injured digital nerve was excised,then bilateral distal ends and proximal ends were sutured,respectively; consequently,the distal and proximal nerve bows were formed.A cutaneous antebrachii lateralis nerve was freed and obtained from the homolateral forearm,then divided equally to 2 parts which were used to bridge the 2 nerve bows.Thirteen patients underwent single end-to-side neuroanastomosis,while other 12 patients underwent end-to-end neuroanastomosis.Results Thirty one patients were successfully followed up for 6 to 8 months.In double end-to-side neuroanastomosis group,12 patients were successfully followed up; anaesthesia and pain of the injured fingers disappeared completely; finger pulp was plump with good flexibility; the average result of sensation measurement was S(4.21 ±1.97),which was significantly higher than those of the other 2 groups; the average result of two point discrimination was 5.4±0.9 mm which was significantly lower than those of the other 2 groups.In single end-to-side neuroanastomosis group,10 patients were successfully followed up; anaesthesia relieved and spontaneous pain disappeared completely,but there was still tenderness; the average result of sensation measurement was S(1.57±0.72); the average result of two point discrimination was 7.2±1.2 mm.In end-to-end neuroanastomosis group,9 patients were successfully followed up; anaesthesia and pain relieved; the average result of sensation measurement was S(3.19± 1.04); the average result of two point discrimination was 7.68±0.8 mm; there were significant differences in results of sensation measurement and two point discrimination between the latter two groups.Conclusion The double end-to-side neuroanastomosis is a valuable method for repairing bilateral obsolete proper digital nerve injuries.

Objective: To explore influence of nursing strategies based on evidence based medical theory on negative emotion and daily behavior in aged patients with coronary heart disease (CHD).Methods: A total of 88 CHD patients, who were treated in our department from Oct 2012 to Mar 2015, were selected.According to random number table, they were randomly and equally divided into routine nursing group and evidence based nursing group (received evidence based nursing based on routine nursing group).Unhealthy lifestyles, scores of self-rating anxiety scale (SAS) and self-rating depression scale (SDS), satisfaction for nursing and incidence rate of major adverse cardiovascular events (MACE) were measured and compared between two groups before and four months after intervention.Results: Compared with routine nursing group after four-week intervention, there were significant reductions in percentages of smoking (40.9% vs.22.7%), drinking (54.5% vs.38.6%), high-fat diet (43.2% vs.29.5%), physical inactivity (45.5% vs.25.0%) and overweight (52.3% vs.29.5%), scores of SAS [(50.4±3.3) scores vs.(45.8±3.2) scores] and SDS [(53.4±4.7) scores vs.(48.0±4.2) scores], and incidence rate of MACE (25.0% vs.11.4%), and significant rise in satisfaction for nursing (86.4% vs.97.7%) in evidence based nursing group (except for the P of overweight was <0.01, others were P<0.05 all).Conclusion: Evidence based nursing mode can improve unhealthy lifestyle and relieve negative emotional status in aged patients with coronary heart disease, which is worth extending in clinic.

Adjuvant treatment, which includes chemotherapy and endocrine therapy, for early breast cancer may impair bone den-sity, resulting in bone loss. The third generation bisphosphonate-zoledronic is an anti-resorptive agent that inhibits osteoclast-mediated bone resorption. This drug can be mainly used in the treatment of hypercalcemia caused by bone metastases of the cancer. The Zome-ta-Femara Adjuvant Synergy Trial revealed that immediate zoledronic acid and endocrine therapy not only prevents bone loss, but also reduces recurrence. The Austrian Breast and Colorectal Cancer Study Group-12 (ABCSG-12) also confirmed that zoledronic acid, when combined with endocrine therapy, could reduce the risk of cancer disease progression and death. Moreover, preclinical studies and clini-cal trials have demonstrated the synergistic antitumor effects of chemotherapy and zoledronic acid. Neo-adjuvant zoledronic acid to re-duce recurrence trials showed that the addition of zoledronic acid to adjuvant chemotherapy significantly reduced the risk of disease pro-gression and death in postmenopausal women more than five years postmenopause at the beginning of the study or over 60 years of age at the baseline. The ABCSG-12 subgroup analysis based on age (≤40 years or>40 years) also showed that zoledronic acid can signifi-cantly improve the prognosis in women who were over 40 years at the study entry. These results suggest that zoledronic acid administra-tion in patients with lowered estrogen levels (naturally or as a consequence of adjuvant treatment) easily exerts anti-tumor effects. How-ever, the optimal dose and duration of zoledronic acid requires further studies. More clinical trials should be performed to provide suffi-cient evidence to support the effectiveness of zoledronic acid in the treatment of early breast cancer.
