Metheds 79 porcelain laminate veneers in front teeth in 38 cases were observed after finished repair and 18-month follow-up. The evaluator examined the restoration for shade, surface lubricity, marginal fit, plaque index and gingival index. Results Shade satisfaction was 82 % and 87 %, surface lubricity satisfaction was 100 % and 100 %, marginal fit satisfaction 84 % after restoration and 18-month follow-up. The plaque index of experince atal groups was 0.73?0.45 and the gingival index of experinceatal groups was 0.28?0.67. There was no statistically significant difference with regard 82 % and to plaque index and gingival index. Conclusion The effect of porcelain laminate veneer in front teeth is satisfactory.

So far,thoracoscopy(video-assisted thoracic surgery) has been maturely used in the field of thoracic and cardiovascular surgery,and already has achieved satisfactory results.In compare,the developing cardioscopy technique to perform intracardiac surgery,due to its own characteristics,was rarely applied as an supplementary clinical means over a long period of time.But more and more studies suggested that cardioscopy technique has it's own advantages in cardiovascular surgery,such as not extend the operation time and aortic clamping time,can provide a clearer operative field,and cause less tissue damage.Although there are a few cases reported completely cardioscopy technique treatment experience,it has not been widely used in clinical because of it's limitations.Even no such kind of research has been reported in China yet.This article aims to review the status of cardioscopy technique and its development prospects,to investigate the feasibility of its'widely clinical application in the future

Objective Cardiac valve replacement with cardiopulmonary bypass ( CPB ) can induce myocardial ischemia-reperfusion injury , which is bad for cardiac function recovery .The aim of the study was to evaluate the myocardial ischemia-reperfusion injury effect of breviscapine intravenously injected before CPB in patients undergoing cardiac valve replacement with CPB . Methods 40 patients scheduled for cardiac valve replacement were randomly divided into two groups :control group and breviscapine group ( n=20).Normal saline 15 mL and breviscapine 0.75 mg/kg was administered with pump within 30 mins after the induction of anesthesia in control group and breviscapine group respectively .Blood samples were taken from jugular vein at each of the five time points: before surgical incision (T0) and at 30mins, at 6, 12, 24h after aortic unclamping (T1-T4) for determination of plasma concentration of car-diac troponin-I (cTnI), creatine kinase isoenzyme (CK-MB) and superoxide dismutase (SOD). Results Compared with T0, the cTnI and CK-MB in both groups significantly increased at T 1-T4 and peaked at T 2 , the SOD in both groups significantly decreased at T 1-T4(P<0.05).Compared with control group, cTnI and CK-MB significantly decreased, while SOD activity significantly increased at T1-T4in breviscapine group (P<0.05). Conclusion The intravenous infusion of breviscapine 0.75 mg/kg before the staring of CPB can relieve myocardial ischemia-reperfusion injury in patients undergoing cardiac valve replacement with CPB , and the mechanism may be related to the anti-oxidative stress effect .

Objective To observe and analyze the oral and maxillofacial appearance of patients with acquired immune deficiency syndrome(AIDS)and to explore the effective detection methods of hunman immunodeficiency virus(HIV)infection,aimed at early diagnosis of HIV infection and AIDS,providing reference for treatment and prevention.Methods 21 6 cases of suspected HIV infec-tion and AIDS therapy-naive patients in the department of infection disease in this hospital,from January 2012 to March 2014,were selected.Oral and maxillofacial appearances,detection methods and its results were retrospectively analysed.Results The main clinical manifestations of patients with HIV infection and AIDS were oral candidiasis,oral hairy leukoplakia,herpes simplex virus infection,Kaposi′s sarcoma,periodontal disease,ulcer disease and other abnormal attribute.All of the 21 6 samples were positive in the preliminary screening,214 cases were confirmed by western blotting(WB),and the sensitivity,specificity and false positive rate were 99.07%,100.00% and 0.926%,repectively.Conclusion Focusing on clinical symptoms and signs in oral and maxillofacial re-gion of patients with HIV infection and AIDS could provide significant references for clinical diagnosis,and combing detection meth-ods of enzyme linked immunosorbent assay(ELISA)and WB could make a definite diagnosis,which might be benefit to make effec-tive prevention and treatment measures and in order to control the infection and improve the prognosis.

[Objective]To observe the degradation process of PDLLA in the intervertebral fusion.[Method]Twenty goats were divided into 4 groups as experimental group,and their L_(3~4)intervertebal spaces were implanted with PDLLA cage containing pieces of graft bone.Animals were sacrificed at 4,8,12,16 wks and specimens were taken for observation of the degradation process and bone fusion by gross observation and electronic microscope.Another 12 goats were used as normal fusion control group.Their L_(3~4)space were grafted with bone block for fusion.[Result]The degradation rate was non-lineal.In the early stage of fusion,the main degradation and decrease of molecular weight was shown at the superficial decomposition.With the proceeding of fusion and degradation,as the kydrolyzation speeding-up,internal decomposition by self-catalyse resulted into the collapse and total disassemble of the PDLLA.The PDLLA cage maintained its shape in the early stage and its biomechanical strength decrease in late stage but was still enough to keep the structure from collapse,till the fusion was achieved in the bone implant area.[Conclusion]The velocity of degradation of PDLLA is slower than the speed of bone regeneration of bone fusion,so the PDLLA cage could provide sufficient support during the process of intervertebal fusion and is a suitable choice of degradative material for cage in the intervertebal fusion.

Objective: Self-enhancement is a kind of motive that urges people to attend exclusively to the positive aspects of himself,it is so intense that individuals even tend to distort the threatening information to some degree so that they can maintain a positive self-view. This research is to investigate the pattern of self-enhancement of Chinese people. Methods: Self-enhancement was measured by requiring participants to make self attribution as well as other attribution of their success and failure on eight factors. Results: There existed strong self-enhancement motive in Chinese individuals. Specifically,Chinese undergraduates attribute their success to inner factors such as personality and effort. This trends also evident in the conditions in which participants were asked to speculate the attribute pattern of other people like his/her mother on their own success and failure. Conclusion: Chinese undergraduates tend to enhance the self-image in other people's eyes.
