Objective To compare the efficacy of percutaneous radiofrequency ablation (PRFA) and repeat hepatectomy for solitary recurrent hepatocellular carcinoma (HCC) with the diameter≤3 cm. Methods The clinical data of 151 patients with recurrent HCC (diameter≤3 cm) who were admitted to the Cancer Center of Sun Yat-Sen University from January 1999 to December 2009 were retrospectively analyzed. Of all the patients, 79received PRFA (PRFA group) and 72 received repeat hepatectomy (repeat hepatectomy group). The survival rate, morbidity and recurrence of the tumor between the two groups were compared. All data were analyzed using t test, chi-square test or Log-rank test, and the survival of the patients were analyzed using the Kaplan-Meier method. Results The mobidities of the PRFA group and repeat hepatectomy group were 13% (10/79) and 36%(26/72), respectively, with a significant difference between the two groups (x2=11.411, P＜0.05). The cumulative 1-, 2-, 3-, 4-, 5-year survival rates were 89.7%, 75.2%, 67.1%, 61.5%, 56.6% in the PRFA group, and 86.0%, 67.6%, 53.6%, 44.1%, 40.2% in the repeat hepatectomy group, with no significant difference between the two groups (x2=1.610, P＞0.05). The cumulative 4-, 5-year survival rates of the PRFA group were significant higher than those in the repeat hepatectomy group (x2=4.682, 4. 196, P ＜ 0.05). The local tumor recurrence rate of the PRFA group was 5% (4/79), and the incisal margin recurrence rate was 3% (2/72) in the repeat hepatectomy group, with no significant difference between the two groups (x2=0.565, P＞0.05). Conclusion As a less invasive treatment method, PRFA is superior to repeat hepatectomy for solitary recurrent HCC with the diameter≤3 cm.

Objective This retrospective study was to explore the efficacy and determine the risk factors of survival for recurrent hepatocellular carcinoma ( HCC) treated by repeat hepatectomy. Methods From January 1995 till December 2010, 60 patients with recurrent HCCs, were treated by repeat hepatectomy.The significance of seventeen clinical or pathological variables in the risk factors of overall survival were assessed. Results The overall survival 1,3, and 5-year survival rates were 76. 3% , 40.7% and 25. 0% (from repeat hepatectomy), and 95. 0% , 62. 6% and 43. 3% ( from initial hepatectomy) , respectively.Univariate analysis indicated that tumor size at initial hepatectomy, recurrence interval from initial hepatectomy, serum albumin(ALB) level, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors(P <0. 05, Kaplan-Meier Log-rank test). Multivariate analysis showed recurrence interval from initial hepatectomy, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors(P<0.05, Cox proportional hazards model).Conclusion Repeat hepatectomy is effective for recurrent HCC. Recurrence interval from initial hepatectomy, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors.

Objective To discuss the allocation of oral medical resource in west area of Chongqing,and investigate the caries prevalence in these population.Methods Study samples was raised with the multistage stratified random cluster sampling method,then data was analyzed to compare the allocation of oral medical.Resource,awareness degree on oral health and caries prevalence in each age grade between urban and rural area.Results In west area of Chongqing,the allocation of oral medical resource and awareness degree on oral health were better in urban area than those in rural area.In each age grade,the caries prevalence is higher in rural area,when compared with that in urban area.In addition,the caries prevalence of 5 years old group and 12 years old group is the same between male and female in both urban area and rural area (P＞0.05).Nevertheless,in 35-44 years old and 65-74 years old group,the caries prevalence was higher in female compared with male in both urban area and rural area (P＜0.05).Conclusion In west area of chongqing,the rural allocation of oral medical resource is bad and needs improvement,the awareness of oral hygiene is weak among population of rural area.In west area of Chongqing,women in 35-44 years and 65-74 years old should pay more attention to caries prevention and treatment.

Objective To compare the advantages and disadvantages of 3D BRAVO and TRICKS for detecting cerebral venous sinus thrombosis (CVST) and to explore the MR scanning methods on CVST.Methods A retrospective analysis was conducted on 40 patients who were diagnosed with CVST in the Fourth Affiliated Hospital of Kunming Medical University from January 2011 to June,2014.All the patients underwent TRICKS scan and 3D BRAVO examination and were classified into 3 groups based on dural venous sinuses,deep cerebral vein and superficial cerebral vein.Detection rates of TRICKS and BRAVO were evaluated and the results were analyzed.Result Detection rates of dural venous sinuses by TRICKS and BRAVO were 98.0％ and 100％ respectively.Detection rates of deep cerebral vein were 92.9％ and 100％ respectively.No significant difference was found (P＞0.05).Detection rates of superficial cerebral vein were 66.7％ and 100％ respectively.Significant difference was found between the two (P＜0.05) Conclusion BRAVO technology can clearly demonstrate the details of CVST,especially in superficial cerebral vein.With the combination use of TRICKS sequences,it will be of higher diagnostic value.

Objective To investigate the correlation between developmental function and pathological behavior in children with autism. Methods A total of 154 children with autism were tested with Revised Chinese Version Psycho-Educational Profile (C-PEP) during 2011 to 2014. Results The scores of fine movement, hand-eye coordination, and oral language of developmental function were lower in the girls than in the boys (t>2.120, P<0.05). Among the children with autism aged 2-7 years, the developmental function was better in the older group than in the younger group (P<0.05);however, it was not better in the children aged 8-10 years and>10 years than in those aged 6-7 years. There was no difference in the scores of pathological behavior between the girls and the boys (P>0.05). Some pathological behaviors were milder in the older group than in the younger group (P<0.05). The scores ofP(pass) in developmental function were positively correlated with the scores ofA(absence) in pathological behavior (P<0.01), and negatively correlated with the scores ofS(severe) in pathological behavior (P<0.01). The scores ofF(fail) in developmental function were negatively correlated with the scores ofA(absence) in patho-logical behavior (P<0.01), and positively correlated with the scores ofS(severe) in pathological behavior (P<0.01). Conclusion Develop-mental function of children with autism is highly correlated with pathological behavior, and the rehabilitation and education of children with autism aged above 7 years should be concerned.

Objective To follow up the rehabilitation, education, and assistive devices utilization of school age children with cerebral palsy. Methods From 2012 to 2015, 80 children with cerebral palsy were called their parents with telephone and filled in the questionnaires. Results 69 children (85.25%) continued to receive rehabilitation, 11 children (13.75%) stopped rehabilitation. 42 children (56.25%) received education in ordinary schools, 15 children (18.75%) received education in special schools, 4 children (5.00%) were nursed in nursing institu-tion, 16 children (20.00%) stayed at home and did not receive any education. The main problem and needing at present were receiving reha-bilitation, receiving school education, relief the rehabilitation cost of more than one institution, etc. 61 children (76.25%) ever applied for as-sistive devices, 19 children (23.75%) did not. The feedback of application process in order were smoothly;applied, but didn't get;the assis-tive devices that received was inappropriate. 29 children (73.75%) needed assistive devices currently, 21 children (26.25%) did not. When asked the category of needed assistive devices at present, 19 parents (20%) answered that they did not know the category of assistive devices well or they did not know which kind of assistive devices they needed. Conclusion It is important to provide quality and quantity rehabilita-tion and education service, popularize the knowledge of assistive devices and their clinical application for cerebral palsy children. Assistive devices providing departments should do more communication with cerebral palsy children and their parents, in order to reduce the waste of resources, and increase the rational use of resources, and provide more benefits for children with disabilities.

Objectives To investigate the correlation between dietary fatty acids intake of pregnant women and neonatal anthropometry at birth. Methods Women in early pregnancy were recruited with appropriate value of weight gain in pregnancy. Instant photography was used to assess the dietary situation in both the second trimester and the third trimester to calculate the intakes of food, energy, macronutrients, and fatty acids. The body weight, height and BMI at birth were evaluated with Z scores. The correlation between dietary fatty acids of pregnant women and neonatal anthropometry at birth were analyzed. Results There were 516 pregnant women recruited in this study. The average intakes of polyunsaturated fatty acids (PUFA) and the proportion of total fatty acids in the two trimesters were 15 . 09 g/d, 23 . 93% and 17 . 18 g/d, 24 . 86%. In the second trimester the intakes of n-6 and n-3 PUFA were 14 . 23 g/d and 3 . 45 g/d, and in the third trimester, n-6 and n-3 PUFA were 16 . 08 g/d and 3 . 81 g/d, the average intakes in the third trimester were signiifcantly higher than those in the second trimester (P??0 . 05 ). The intake of DHA ( 64 . 43 mg/d) in the second trimester was lower than that in the third trimester 75 . 12 mg/d, (P??0 . 05 ).The dietary intakes of n-3 PUFA, n-6 PUFA and n-6/n-3 ratio in the second trimester were positively correlated with neonatal BMI r=0 . 142~0 . 189 , P??0 . 05 ). Conclusions The dietary ratio of n-6/n-3 PUFA in the second trimester was positively correlated with neonatal BMI, suggesting that moderately increasing the intake of n-3 PUFA may play a positive role in reducing childhood obesity.

Fever and sweating are the most common clinical symptoms, which are important parts in the inquiry of traditional Chinese medicine (TCM). Just as Zhang Jingyue said, Firstly inquire for cold and heat and secondly in-quire for the sweating. It placed both symptoms as priorities in the collection of disease history. In the clinical prac-tice, febrile diseases refer to acute exogenous diseases infected by warm evil with the main symptom of fever. And fever is almost throughout the entire process of febrile diseases. It is also known as Han-Bing for the visible varia-tion of sweating in its entire disease process. It is important to identify the abnormality of sweating for the determina-tion of the severity febrile diseases and the level of body fluid shortage. Therefore, two main symptoms for the diag-nosis of febrile diseases are particularly prominent and important. The reasons of sweating and fever in febrile dis-eases have been explored so much but the relationship between them is less which is extremely essential to learn more about febrile diseases. So we are expected to explore this topic to make better use of theories of febrile dis-eases.

Objective To investigate the preliminary experience of mechanical thrombectomy with a tri-axial system of the Solitaire AB stent through a Neuro delivery catheter to treat intracranial large artery occlusion. Methods A tri-axial system was used to deliver the Solitaire AB stent through a Neuro delivery catheter to provide intracranial aspiration in close proximity to the stent. This technique was used in 1 case of acute middle cerebral artery occlusion and 1 case of acute basilar artery occlusion. Results Successful revascularization was achieved in these 2 cases. Thrombolysis in cerebral infarction (TICI)score was 3. The clot length of acute middle cerebral artery occlusion was 3 cm and the modified Rankin Scale (mRS)score of this case was 3 at 90 days follow-up. Another patient with acute bilateral vertebral occlusion was revealed successful recanalization by angiography. Conclusion The results suggest that this technique of a tri-axial system used of the Solitaire stent through a Neuro delivery catheter can effectively retrieve clots from the occlusive artery and minimize the chance of antegrade blood flow dislodging the thrombus.
