50% was seen in 7 cases after TACE and PEI(30%),and the 1?3?5 year′s survival rate was 52%?35%? and 9%,respectively.Conclusions Adjuvant chemotherapy was hardly beneficial to the treatment of liver cancer with parasitic blood supply after TACE, while PEI enhanced effect of TACE as a supplementary therapy as judged by long term survival. The change of sIL-2R, AFP level was a sensitive indicator for the outcome of the treatment.

Objective To investigate the effectiveness of implantation of homologous cancellous and autologous red marrow under endoscope in the treatment of traumatic bone nonunion or bone defect.MethodsTotally 25 patients with traumatic bone nonunion or bone defect were enrolled in this study.The lesion involved the tibia bone in 9 cases,the femur in 13,and the humerus in 3.The grafts were sized 1 to 6 cm in length(mean,2.7 cm).Before the implantation of the cancellous bones,the scar fibrous tissues within the nonunion were removed completely by endoscopy,and then autologous red marrow obtained from the iliac crest was injected.ResultsAll the patients were followed up for 12 to 36 months(mean,25 months).The surgical wounds healed primarily in all of the cases without injuries to the blood vessels and nerves.Bony union was achieved within 4 to 9 months(mean,5.1 months) in 23 of the patients,the other 2 failed because of breaking and loosing of internal fixators.No patient developed re-nonunion and infection.ConclusionsImplantation of homologous cancellous and autologous red marrow under endoscope is effective for traumatic bone nonunion or bone defect with a low rate of complication and high rate of bony union.Since no need to harvest the ilium bone,the method is minimally invasive for the patients.

Objective To determine enterobacteria DNA load in venous blood of febrile surgical patients using real-time quantitative polymerase chain reaction (RQ-PCR), to study the correlations between DNA load and vital signs/blood cell count, and to compare the difference between different detection methods in terms of positive rates.Methods A total of 72 blood samples were obtained for bacterial cuhure and RQ-PCR.The correlations of enterobacteria DNA load with body temperature, heart rate, while blood cell count,and percentages of leukocyte and lymphocyte were then analyzed.Results The enterobacteria positive rate determined by RQ-PCR (63.89％) was significantly higher than that by bacterial culture (9.72％) (F =4.383, P =0.036).The DNA load was significantly correlated with both body temperature and heart rate (P =0.006, r =0.323;P =0.000, r =0.411), but not with white blood cell count, percentages of leukocyte and lymphocyte, and age (P=0.438, r=0.093;P=0.825, r=0.027;P=0.451, r=-0.090;P =0.096, r =0.198).Conclusions RQ-PCR can quickly determine the enterobacteria DNA load in peripheral blood with high sensitivity.Routine blood cell count may not accurately reflect the enterobacteria DNA load in blood.Body temperature and heart rate may be influenced by various factors.

Objective To evaluate the CT and MRI imaging features of primary ventricular lymphoma ,so as to provide a reference for the diagnosis and differential diagnosis of the disease .Methods The clinical data and imaging findings of primary ventricular lymphoma in one case was retrospectively analyzed with literature review and compared with primary lymphoma in parenchymal brain .Results Slightly high density tumor presented with regular shape in the trigone of lateral ventricles on CT findings , and slightly low signal intensity on T 1 and slightly high signal intensity on T 2 appeared on MRI findings with small cystic necrosis in tumour .An enhancement scan showed obviously enriched, and there was perilesional edema.After 14 day’s dehydration treatment, rechecked indicated that the lesions were significantly en-larged, the shape were irregula , the area of cystic necrosis was enlarged , heterogeneous enhanced scanning were enhanced , perilesional ede-ma became more heavier , and the imaging feature of “closed fist” appeared .It was proved to be diffuse large B cell lymphoma with surgical pathologic examination , and there was no lymphoma in other regions of the body with whole body PET-CT examination , which was clinically diagnosed as primary ventricular lymphoma .Conclusion Primary ventricular lymphoma is rarely reported ,and it has similar imaging mani-festations with primary lymphoma in parenchymal brain .The combination of multiple imaging modalities will be helpful to diagnosis and dif -ferential diagnosis for the suspected patients .

Objective To measure the dynamic and static frictional resistances between different self-ligating orthodontic brackets and different combination of tandem archwires.Methods On standard model the upper right quadrant Damon Q self-ligating brackets was pasted as team A,3M Smart clip self-ligating brackets as team B and Forestadent Quick 3.0 self-ligating brackets as team C respectively.Nickel-titanium archwires of 0.012 inch and 0.016 inch and two nickel-titanium archwires of 0.014 inch were applied to simulate sliding in the brackets and measure the friction changes in brackets and archwires,so as to explore the frictional resistance between different combination of the tandem archwires and different self-ligating brackets.Results When using the combination of two 0.014-inch nickel-titanium tandem archwires,the static frictional resistances was significantly different (P＜ 0.05):team A ＜team B ＜team C while the kinetic frictional resistance was also significantly different (P＜0.05):team A ＜team B ＜team C,When using the combination of 0.012-inch and 0.016-inch nickel-titanium tandem archwires,the static frictional resistances was significantly different (P＜0.05):team A＜team B＜team C,while the kinetic frictional resistance was also significantly different (P＜0.05):team A＜team B＜team C.Gonclusion There are different frictional resistance in different kind of self-ligating brackets and different combination of the tandem archwires.The combination of two 0.014-inch nickel-titanium tandem archwire applied to Forestadent Quick 3.0 self-ligating brackets has the biggest frictional resistance while the combination of 0.012-inch and 0.016-inch nickel-titanium tandem archwire applied to the Damon Q self-ligating brackets has the lowest frictional resistance,which enables the teeth to move at the fastest speed and facilitates the following use of the edgewires.

Objective To investigate the clinical significance of the antenatal detection of four indices of coagulation(PT,APTT, TT,FIB),D-dimer(DD)and platelet(PLT)in the judgment of parturient coagulation function and bleeding risk.Methods 795 pregnant women and childbearing age non-pregnant women with physical examination in this hospital from June 2012 to September 2013 were collected and divided into the normal pregnancy group(early pregnancy,middle pregnancy,late pregnancy,parturient pe-riod),obstetric accident group,pregnancy complicating other disease group and healthy control group.At the same time,PT, APTT,TT,FIB,DD and PLT were detected and the related statistical analysis was conducted.Results DD and FIB in the normal pregnancy group were significantly higher than those in the healthy control group(P<0.05),PT and APTT were significantly low-er than those in the healthy control group(P <0.05),TT had no statistically significant difference between these two groups(P >0.05 );DD and FIB in the obstetric accident group and the pregnancy complicating other disease group were significantly higher than those in the normal pregnancy group(P <0.05),while PT was significantly lower than that in the normal pregnancy group(P <0.05).PLT in the obstetric accident group and the pregnancy complicating other disease group was significantly lower than that in the normal pregnancy group(P <0.05).The sensitivity and specificity of the combined detection of 3 indices in diagnosing the ob-stetrical accidents were greatly superior to those of the single index detection or the combined detection of two indices.Conclusion The prenatal combination detection of four coagulation indices,DD and PLT can preliminarily judge the coagulation status of preg-nancy period in pregnant women,help to treat abnormal bleeding of pregnant women an possess the important guidance significance in formulating the labor scheme and preventing the occurrence of obstetric accidents.

Objective To assess the nutritional risk of patients with inflammatory bowel disease (IBD).Methods The nutritional status of 112 IBD patients from PUMC Hospital were evaluated by Nutritional Risk Screening 2002 (NRS 2002).Using Chinese standard,a body mass index (BMI) that was lowered than 18.5 kg/m~2 according to clinical material was regarded as malnutrition,and the score was recorded as 3.The se-verity of ulcerative colitis (UC) was evaluated using True-Love criteria as mild,moderate,and severe.Crohn's disease (CD) was evaluated using Harvey-Bradshaw Index as in remission stage (≤4),moderately active stage (4-8),and severely actively stage (≥9).Results All these 112 patients,including 70 UC cases and 42 CD cases,were evaluated by NRS2002.Forty-five patients (40.2%) were judged as at the risk of malnutrition.The incidence of malnutrition was significantly higher in CD patients than in UC patients (52.4% vs.32.9%,P<0.05).It was also significantly correlated with the severity of disease.In patients with severe IBD,the rate of mal-nutrition evaluated by BMI according to clinical material was significantly lower than the rate of nutritional risk.Con-clusions The risk of malnutrition is high in IBD patients.NRS 2002 can be used for nutritional risk screening.

AIM The effects of GW501516, a peroxisome proliferator-activated receptor β (PPARβ) agonist, in long term diet induced obesity (DIO, high fat and maltose diet for 4 months) mice were evaluated, and the efficacy of GW501516 against insulin resistance and the involved mechanism was investigated. METHODSMice were divided into 3 groups: normal control, DIO model and DIO model+GW501516. GW501516 (10 mg·kg-1·d-1) was administered by ig once a day for 14 d. During the treatment, body weight and food intake were monitored every other day. The oral glucose tolerance test, and the serum biochemical parameters including the serum triglyceride, total cholesterol and high density lipoprotein cholesterol (HDL-C) levels were measured according to the specifications. To confirm the GW501516-mediated PPARβ activation, the mRNA levels of downstream genes related to glucose, lipid metabolism and energy expenditure was measured. RESULTS GW501516 treatment effectively improved the glucose intolerance, increased the area under the glucose curves[DIO model, (32.4±4.6) mmol·h·L-1 compared with DIO model+GW501516, (23.4±2.5) mmol·h·L-1, n=7-8, P<0.05], normalized the fasted blood glucose, and increased serum HDL-C level, besides, histological analysis revealed the decreased hepatic lipid accumulation and hypertrophy of hepatocyte in DIO mice. Moreover, RT-PCR results indicated that carnitine palmitoyltransferase 1b, uncoupling protein 2, uncoupling protein 3 and glucose transport protein 4 were all upregulated. CONCLUSIONGW501516 significantly ameliorates glucose intolerance, decreases fasted blood glucose and hepatic steatosis, which might be related to ① the enhancement of fatty acid oxidation and energy uncoupling in muscle, and ②the improvement of insulin-stimulated glucose transportation in skeletal muscle in the long term DIO mice.
