Objective To prove that valve sparing aortic root reconstruction may have an impact on the outcome and longevity of the repair for patients with acute type A aortic dissection.Methods Clinical data of 98 consecutive AAAD patients undergoing the valve sparing aortic root reconstruction were analyzed.The postoperative follow-up and the clinical effect of the procedure were retrospectively analyzed.Results Pre-operative grade of aortic insufficiency was(2.3 ± 0.5), CPB-time was (217.8 ± 43.1)min, aortic cross clamp time was(142.7 ± 37.4)min and stay on ICU (11.1 ± 5.7) days, while hospitalisation was(14.3 ± 3.2) days.8 patients(8.2％) died peri-operatively.None of the early deaths were valve-related.Rethoracotomy rate was 3.1％.All patients followed up(19.3 ± 7.6) (6-68) months.Survival at 1 year was 90.8％.Freedom from valvular reoperation was 97.9％ at 3 years.At last investigation, mean grade of aortic insufficiency for AADA was 0.5 ± 0.3 (0-3).Conclusion Regardless of the underlying indication, the aortic valve preserving reimplantation technique can be performed with favourable functional results.

Purpose To study the expression of HNF-1β in different type ovarian carcinoma and to explore the diagnostic value of HNF-1β in the diagnosis of ovarian clear cell carcinoma. Methods Immunohistochemical EnVision method was used to detect the ex-pression of HNF-1βin 27 clear cell carcinomas, 35 high-grade serous carcinomas, 21 endometrioid adenocarcinoma, 10 mucious carci-nomas, 13 metastatic Krukenberg tumors, and 2 transitional carcinomas. Results All of ovarian clear cell carcinomas variably ex-pressed HNF-1β and the positive rate of HNF-1β in ovarian cleat cell carcinoma was 85. 2%. Of 21 ovarian serous carcinomas, the nuclear positive of HNF-1β was 4 and HNF-1βpositive rate was 2. 9%. There was 5 HNF-1βexpression in endometrioid adenocarci-noma and the positive rate of HNF-1β was 23. 8%. The positive rate of HNF-1β in mucious carcinoma and metastatic Krukenberg tumor was 60. 0% and 53. 8%, respectively. No HNF-1βexpression was seen in transtional cell carcinoma. The sensitivity and speci-ficity of HNF-1β in the diagnosis of ovarian clear cell carcinoma was 85. 2% and 76. 5%. Conclusions HNF-1β may be a higher sensitive marker for the diagnosis of ovarian clear cell carcinoma. The diffuse and strong positive of HNF-1βmay have higher specific for diagnosis of ovarian clear cell carcinoma.

Objective To study the changes and clinical significance of serum kalium,natrium,chlorine,calcium and glucose in children with febrile convulsion(FC).Methods Serum kalium,natrium,chlorine,calcium and glucose concentrations were measured in 41 children with FC(FC group),30 children with fever and without convulsion(fever group) and 30 normal children(normal group) by automatic biochemical detector.Results Serum kalium and calcium concentrations had no significant difference between FC group and fever group,but they were significantly lower than those of normal group(F=5.965,3.048 P0.05).Conclusions There are hyponatremia,hyperglycemia and lowered blood kalium and calcium in patients with FC.Hence,while treating the patient with FC,the disturbance of blood electrolytes and glucose need be corrected to avoid the recurrence of FC and the progressive injury of important organs such as brain.

OBJECTIVEThis study aims to investigate the caries status of the first permanent molar and primary tooth among 7- to 9-year-old children in Tangshan city and the correlation between caries of primary tooth and the first permanent molar.

METHODSA stratified cluster sampling method was used on the basis of the Basic Approach of Oral Health Survey of WHO and the Guideline of the Third National Oral Health Survey. A total of 10 primary schools were randomly sampled in clusters that included 51 primary school sampling spots in Tangshan. The caries status of 1 794 children aged 7 years to 9 years was examined.

RESULTSThe prevalence rate of the first permanent molar caries was 47.49% (852/1 794), the mean number of DMFT was 1.30 ± 1.59, the mean number of DMFS was 1.96 ± 3.40, and the filling rate was only 2.35% (20/852). The preva- lence rate and mean DMFT of the first permanent molar caries showed significant difference between different ages and genders (P < 0.05). However, the mean DMFS of the first permanent molar caries only showed significant difference between the various ages (P < 0.05). The prevalence rate of the primary tooth caries was 83.11% (1 491/1 794), the mean number of dmft was 4.82 ± 3.55, the mean number of dmfs was 6.51 ± 5.61, and the filling rate was 12.41% (185/1 491). Caries of primary tooth was the first permanent molar caries risk factor [r = 0.277, OR = 5.736, P = 0.00, 95% CI (4.175, 7.881)]. Significant correlation was found between the caries of primary tooth and first permanent molar (r = 0.274, P < 0.001).

CONCLUSIONCaries status of the first permanent molar among 7- to 9-year-old children in Tangshan city is serious. Caries status of primary tooth may play an important role in predicting the first permanent molar caries in clinic and prevention.

Objective:To evaluate the effects of the flowable resin used as pit and fissure sealant using different etching adhesive systems.Methods:60 caries-free extracted human premolars were randomly divided into 4 groups(n =1 5)and treated by Gluma, NT and 3M-Z350 flowable resin(group A);Clearifil SE Bond adhesive and 3M-Z350 flowable resin(group B),phosphoric acid etching,3M-Z350 flowable resin and phosphoric acid etching(group C)and 3Mconcise sealant(group D)respectively.After pro-cessing the tooth surface the pit and fissue of 1 0 sample in each group were sealed.The microleakage was measured by 1 % methyl-ene blue staining(n =8).The material-enamel interface was observed by SEM(n =2).The shear bond strength of the column-shaped samples with the diameter and the height of 3 mm(n =5)on the mesial or dental surface was examined by a test machine. The sealant cartridges and flowable resin cartridges with the diameter and height of 4 mm were used for the crushing strength exami-nation(n =1 0).Results:There was no significant difference in the microleakage among the 4 groups.SEMobservation showed that the resin tags of group A were long and dense and the resin tags of group B were short and sparse,bubbles and cracks were found on the local site in group A and B.The resin tags of group C were long and thin,but combined with tooth tightly;the resin tags of group D were short and dense;the penetration was poor at the bottom of the fissures in the 4 groups.The shear bond strength of Group A was the highest(P <0.01 ),that of group C was higher than that of group B and D(P <0.05).There was no significantly difference between group B and D(P >0.05).The compressive strength of flowable resin groups was higher than that of fissure seal-ant group(P <0.05).Conclusion:The shear bond strength and compressive strength of all-etching bonding system combined with flowable resin is superior to that of self-etching bonding system combined with flowable resin and the traditional sealant.Using Prime&Bond NT bond after acid etching may improve the shear bonding strength.

Objective The aim of this study was to assess the value of △Np63α in predicting tumor recurrence after curative resection in esophageal squamous cell carcinoma (ESCC) patients.Methods We analyzed △Np63α protein cxpression in 304 clinicopathologically characterized ESCC cases by immunohistochemistry.Results We found △Np63α expression was positive in 122 (40％) of 304 cases.△Np63α expression was higher in the cancer tissue than in non-tumorous control tissue at protein level(P =0.034).There was a significant difference of △Np63α expression in patients categorized according to invasive depth (P =0.001),tumor position (P =0.001) and lymph nodes metastasis condition (P =0.001).Multivariate analyses showed that △Np63α was an independent prognostic marker for ESCC recurrence.Conclusion △Np63α is associated with outcome of ESCC and can be a novel predictor for poor prognosis of ESCC patients after curative resection.

Objective To analyze the effect of the false lumenstatus of different methods in a single center.Methods From January 2010 to December 2015,391 cases of acute Stanford A aortic dissection were treated in our center.139 cases(of which 108 malesand 31 females) were finally selected after excluding the cases who died during hospitalization,whose perioperative clinical data were incomplete,follow-up information were incomplete,and DeBakey type Ⅱ aortic dissection and the cases with descending aorta dilatation.The average age was(50.3 ± 11.6) years(22-76 years).According to the methods for aortic arch and descending aorta,139 cases were divided into 5 groups:24 cases in AR(including ascending aorta replacement,ascending aorta + hemi-arch replacement and ascending aorta + island-arch replacement),9 cases in AR + SET (including ascending aorta + hemi-arch replacement + stent elephant trunk and ascending aorta + island-arch replacement + stent elephant trunk),42 cases in Arch + SET(ascending aorta + arch replacement + stent elephant trunk),22 cases in AR + TBS (ascending aorta + triple branched stent) and 42 cases in AR + FS(ascending aorta + arch fenestrated stent).Statistical analysis the size of true lemen and the status of false lumen among these five groups in the level of aortic arch,the distal end of stent,diaphragm,celiac artery,renal artery and iliacartery postoperatively.Results Different levels of descending aorta in each group have showed arying degrees of true lumen open and thrombosisof false lumen during follow-up period.Among them,cases with aortic arch treatment and stent implantation have showed higher ratio of thrombosis of false lumen.Effects of different stents were similar,which all promoted the process of thrombosis of false lumen.Conclusion Three methods for aortrc arch and desc ending aorta repair including Cronus (R),triple branched stent and arch fenstrafed stent had similar clinical aortic false lumen closure rate.Three methods had similar long term effect.
