Objective:To retrospectively study the effect and curative effectiveness of ethanol in treating HCC with portal vein tumor thrombus(PVVT) through transcatheter fed arterial super selective infusion and super selective arterial embolization of main tumor,appraise the effect of ethanol in local treatment,in order to improve the clinical curative effects on the patients. Methods:The data of study from 86 cases of HCC with PVVT in our hospital between 2001~2004 year,to the fed artery of portal vein tumor thrombus super selective infusion ethanol or ethanol and gelfoam or ethanol and lipiodol,also through transcatheter super selective embolizing the fed arterys of main tumors including TACE or ethanol and lipiodol in 86 cases HCC. The course of observation was between 2001 and 2007year. Results:The super selective fed arterial embolization of PVVT and main tumors were successful in all cases;After treatment,ascites disappeared or obviously reduced in 66.3%(57/86) of cases,reduce in 23.2%(20/86),did not reduce in 10.5%(9/86);After 7~10d,hepatic function obviously improve or improve in 71%(61/86),did not obviously change in 11.6%(10/86),lowered in 6%(5/86),with no obvious lowering of hepatic function or hepatic function failure.The survival rates at 3,6,12,24,36months were 97.7%(84/86),95.5%(82/86),72.7%(62/86),47.7%(41/86) and 16.3%(14/86) respectively. Conclusion:The therapy of ethanol through catheter super selective PVVT fed arterial infusion is safe and effective,combined with super selective TAE or TACE to the fed artery of main tumor,could obviously improve the quality of life of the patients and could improve the survival rate.

Objective:To retrospectively evaluate the safety,technical success rate,and effectiveness of ultratranscatheter tumor feeding arterial embolization with ethanol and lipidol for SHCC,and to explore the new therapy for SHCC. Methods:To 95 cases carry out hepatic selective arterial angiography for SHCC by CT or MRI be diagnosed and clinical very doubt be SHCC,after was diagnosed by DSA,to transcatheter ultraselective subsegmental feeding artery with microcatheter for tumor,employ ethanol and lipidol (1/1) to full fill embolized 143 tumors. Results:Technical success rate was 100% for the ultraselective subsegmental feeding artery transcatheter and embolizatoin in SHCC,There were no major complications in all cases.Before embolization ,the diameter of tumors were 0.5~3cm,average diameter 2.3 cm. after tumors were embolized,average diameter 1.2 cm. The 1,3and 5 year recurrence rates were 19%(18/95),27%(26/95),37%(35/95),and the survival rates were 100%(95/95),85%(81/95),67%(64/95) respectively. Conclusion:Its effectiveness was very notable,there were no major complications and recurrence rates was less than surgical resection in ultraselective transcatheter tumor feeding arterial embolization with ethanol and lipidol for SHCC,It should become the first selective therapy for SHCC.

Objective:To evaluate the safety,technical success rate,and effectiveness of transcatheter superselective arterial chemoembolization(TACE)for unresectable lung cancer and the metastases tumor with rich blood feeding in lung.Methods:Using Japan Shimadzu 1250Ma CCD DSA X machine,4F RH or 4F YASHIRO catheter and 3F SP microcatheter were employed in superselective chemoembolization for feeding artery of lung cancer and the metastases tumor with rich blood feeding in lung with lipiodol and 2～3 species chemodrug.The period of repetitive treatment was 4～6weeks.After treatment,the change of the symptoms,images of neoplasm and the survival rates were observed.Results:Transcatheterization and embolization were successfully completed in 88 out of 90 cases.Technical success rate was 97.8% without spinal damage occuring.After 2～3 time treatment,the symptoms of the patients obviously improved in 87cases(96.7%);neoplasm notable shrank in 82 cases(91.1%),partly shrank in 5 cases(6%),not shrinking in 3 cases(3.3%).The survival rate respectively at 6 months,12 months,24 months,36 months were 98.8%(89/90),93.3%(84/90),83.3%(75/90)and 53.3%(48/90).Conclusions:The technical success rate at Superselective transcatheter arterial chemoembolization for feeding artery of the neoplasm that rich blood fed in lung is high.Complications rate is lower.Its effectiveness is more notable than bronchial artery chemodrug infusion.

All-ceramic dental materials could meet the requirements for extraordinary aesthetics and ex-cellent biocompatibility in vivo, thus are widely utilized in prosthetic dentistry. Since the all-ceramic materials have low strength reliability and the disadvantage is recently concerned, the relevant research has been the focus in the area. The purpose of this artical is to review the relevant studies and with focus on the factors that influence the strength including material component, microstructures and manufacture process, as well as strength improv-ing approaches such as ingredient alteration, fabrication optimization and surface treatment. As for various strength testing methods, all the existing test methods are compared and evaluated.

Titanium & titanium alloy are popular in dentistry as dental material because of their good mechanical properties and extremely good biocompatibility. The bonding strength between the titanium and the resin agent is the decisive factor in evaluating the success of resin-bonded restoration. Appropriate surface treatment on the titanium is an effective way to reinforce the bending strength. The purpose of this review is to summarise the relevant studies and introduce some latest findings.

Syncope is a common pediatric emergency event,which can be caused by various metabolic disorders different from other illness. The major metabolic anomalies include hypoglycemia, hyperventilation,electrolytes imbalance,hypoxemia and others, in which hypoglycemia is caused by hyperinsulinemia,pituitary and adrenal disease, diabetes, ketotic hypoglycemia, inherited metabolic disorders of sugar, organic acids and amino-acids,etc. This article introduced the common metabolic anomalies and their causes,diagnosis and therapy.

Objective To evaluate the curative effect in treatment of hepatic metastases tumor with poorly blood supply through superselective transcatheter nutrient arterial full chemoembolization.Methods 75 cases of hepatic metastases tumors with poorly blood supply were treated by full chemoembolization through superselective transcatheter nutrient arterial infusion under DSA guided.Results After treatment 2～3 months,CT scans showed that totally 202 tumors in 75 cases,the tumors were fully filled with lipiodol in 189,large part in 11 and not well in 2.159 tumors were obviously shrunk,41 tumors were shrunk part,2 tumors were not obviously shrunk.The survival rate in 6 months,12 months,24 months,36 months and 3～5 years was 100%(75/75),85.3%(64/75),55%(41/75),42.7%(32/75)and 20%(15/75)respectively.Conclusion The transcatheter superselective nutrient arterial full filling chemoembolization for hepatic metastases tumor with poorly blood supply is a effective therapy.

Objective:To evaluate the feasibility of the 3-D surface reconstruction by multislice spiral CT(MSCT) technique in the diagnosis of impacted teeth in maxilla.Methods:Eighty two cases with impacted teeth in maxilla were examined with volumetric CT scan using MSCT,the dental reconstruction images were obtained with multiplanar reformation technique and 3D-reconstruction technique.Results:Dental surface 3D-reconstruction image could display the shape,location and eruption orientation of the impacted teeth clearly.Conclusion:3-D surface reconstruction by MSCT can provide valuable diagnostic and anatomic information of the impacted teeth in maxilla.

Neonatal inherited metabolic diseases (IMD) screening has been widely conducted worldwide. Tandem mass spectrum (MS/MS) is the main procedure of IMD screening. As a new technique, gene sequencing has been put into practice for IMD screening. Nowadays, the morbidity and disease spectrum of IMD in China is still unclear. A summary of general and single morbidity, and disease spectrum of China's IMD from publications of MS/MS screening could provide evidence for establishing neonatal IMD's genetic test and formulation of laws and regulations.
