0.05). There was only 2/109 cases (5.8%) need a second course of antibiotics because of likely infection and 102/109 cases (93.5%)need not any moor antibiotics. The mean period of antibiotic treatment in group Ⅰ, group Ⅱa and group Ⅱb were (1.2?0.5) days,(4.8?0.8) days and (9.3?1.8) days,respectively.There were significant differences(all P

Objective To evaluate the effect of transcatheter arterial chemoembolization (TACE) and delayed surgery for infant hepatoblastoma.Methods TACE was performed with the initial digital subtractive angiography (DSA) under general anesthesia 1-3 times in 8 infants with huge hepatoblastoma, whose age was 2 to 12 months. DSA was done via arterials in hepatoblastoma each time before chemoembolization. The arterials were perfused with chemodrugs and suspensions in ultrasome iodized oil , and were blocked with spring rings. DSA findings indicated that the tumor shrank without new tumorous arterials after 1 month in 6 cases, and 4 of them showed no tumorous staining, and the delayed surgery was performed successfully 1 week later in 6 infants. One boy underwent systemic chemotherapy alone during 6 months after 3 times of TACE. Results TACE therapy did not encounter any major technical problem or toxic reaction caused by chemotherapy. The following DSA test 4 weeks later did not detect any new tumorous vessels in 6 cases. Six children received TACE and surgery had been followed-up with no tumor recurrence for months averagely. The boy underwent TACE and venous chemotherapy for 6 months , without surgery , had been followed-up for 48 months until the present report. CT, AFP and DSA did not show any hints of tumor recurrence. Six cases receiving 3 times TACE combined with surgery survived without tumor recurrence. Conclusions TACE is a very effective, safe and helpful therapy for hepatoblastoma, which stressed the repeated use of spring ring to block tumor vessels lastingly if necessary. If surgery is required, DSA test is needed beforehand to detect new tumorous vessels or neoplasm. If there is any , TACE is repeated. TACE combined with surgery may provide an additional promising choice in the treatment of hepatoblastoma, and repeated TACE alone may cure hepatoblastoma in infants.

Objective To explore the association of ubiquitin-specific proteases 24 (USP24) gene polymorphisms with susceptibility to sporadic Parkinson's disease (PD) in the Han Guangdong population. Methods From August, 2006 to January, 2014, single nucleotide poly-morphisms (SNPs) of rs12138592 and rs6671533 in the intron region of USP24 were genotyped in 200 patients with sporadic PD and 200 healthy controls using the SNaPshot technique. Results There was significant difference in the allele and genotype frequency of rs12138592 between the patients and the controls (P<0.01), and no significant difference was found in the allele and genotype frequency of rs6671533 (P>0.05). Conclusion The SNP of rs12138592 in the intron region of USP24 is associated with the susceptibility to sporadic PD in the Han Guangdong population, and the A allele may contribute a protective roles to PD.

Objective To study three-dimensional reconstruction system (IQQA-Liver) in evaluation of resection volume and margin of hepatocellular carcinoma.Method Data of 51 hepatocellular carcinoma patients undergoing hepatectomy from March 2014 to October 2015 were analyzed retrospectively.All patients received preoperative ultrasound and CT/MIR evaluation.Three-dimensional reconstruction system (IQQA-Liver) was used to reconstruct tumor shape and location,the relationship between tumor and adjacent vessels or bile ducts.Then liver volume,liver resection volume,residual liver volume and surgical margin were calculated and compared with the actual resection liver values and actual margin.Results Images of three-dimensional reconstruction system (IQQA-Liver) were accurate,clear and directly perceived.In terms of the resection liver volume and resection margin,there was no significant difference between the predicted results and actual results [resection liver volume:(412.93 ± 471.26)cm3 vs.(487.02±529.01)cm3,t=0.75,P=0.46,resection margin:(13.72 ± 4.58) mm vs.(13.92 ±4.21)mm,t =0.23,P =0.82].The predicted resection liver volume was significantly correlated with the actual resection volume (r =0.91,P ＜ 0.01),the predicted resection margin was also correlated with the actual resection margin (r =0.89,P ＜ 0.01).Conclusion Three-dimensional reconstruction system (IQQALivcr) could accurately assess the resection volumc and margin of hepatocellular carcinoma.

Methods81 PD cases and 100 ethnically matched controls were investigated USP24 gene rs12138592 A/G polymorphism with polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). ResultsThe incidence of GG genotype was 77.8% in the cases and 62.0% in the controls (χ2=5.213,P=0.022), and the G allele was 88.3% in the cases, 79.5% in the controls (χ2=4.980，P=0.026). ConclusionThe G allele and GG genotype of USP24 gene rs12138592 A/G polymorphism can increase the risk of suffering from PD.

OBJECTIVETo explore evolution rules of phlegm and blood stasis syndrome ( PBSS) in hyperlipidemia and atherosclerosis (AS) using NMR-based metabolic profiling and metabonomic approaches based on formulas corresponding to syndrome.

METHODSTotally 150 SD rats were divided into the normal group, the model group, the Erchen Decoction (ED) group, the Xuefu Zhuyu Decoction (XZD) group, the Lipitor group, 30 in each group. The hyperlipidemia and AS rat model was duplicated by suturing carotid artery, injecting vitamin D3, and feeding with high fat diet. ED and XZD were used as drug probes. Blood samples were withdrawn at week 2, 4, and 8 after modeling. Blood lipids, blood rheology, histopathology and metabolomics were detected and analyzed. Results Results of blood lipids and pathology showed hyperlipidemia and early AS rat models were successfully established. At week 2 after modeling, levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) significantly increased, which reached the peak at week 4 and maintained at higher levels at week 8. ED exerted obvious effect in improving TC and LDL-C levels of early models, while XZD could greatly improve levels of TC and LDL-C of late models. Rheological results showed at week 2, there was no significant difference in whole blood viscosity, plasma viscosity, or hematocrit between the model group and the normal group (P > 0.05). At week 4 partial hemorheological indicators (such as plasma viscosity) were abnormal. Till week 8 whole blood viscosity, plasma viscosity, and hematocrit were significantly abnormal (P <0. 05, P < 0.01). As time went by, whole blood viscosity, plasma viscosity, and hematocrit showed gradual increasing tendency in the ED group, while they showed gradual decreasing tendency in the XZD group. Results of metabonomics showed significant difference in spectra of metabolites between the normal group and the model group. As modeling time was prolonged, contents of acetyl glucoprotein and glucose in the model group increased in late stage, which was in. line with results of blood lipids and hemorheology. ED showed more obvious effect in early and mid-term modeling (at week 2 and 4), and increased contents of partial metabolites (such as choline, phosphatidyl choline, glycerophosphocholine), but these changes in the XZD group were consistent with those of the model group. In late modeling (at week 8) XZD showed more obvious effect in improving contents of lactic acid, acetyl glycoprotein, LDL, creatine, choline, and glucose.

CONCLUSIONSED and XZD not only showed regulatory effects on lipid disorders, but also could improve dysbolism of Chos. In formulas corresponding to syndrome, damp-phlegm was main pathogenesis of hyperlipidema and AS in early and mid stages. Blood stasis syndrome began to occur along with it progressed. Phlegm can result in blood stasis and intermingles with stasis. Phlegm turbidity runs through the whole process.
