Objective To discuss the contrast-enhanced ultrasonography diagnostic value of the liver low-density focus on contrast-enhanced CT. Methods The contrast-enhanced ultrasonography results of 47 cases of the liver low-density focus on contrast-enhanced CT. were retrospectively analyzed. Results The pathological diagnosis in 47 focuses was metastatic carcinoma 20 cases, inflammatory pseudotumour 9 cases,hepatic hemangioma 6 cases, primary liver carcinoma 4 cases, cyst 2 cases, abscess 2 cases, tuberculosis 2 cases, FNH (focal liver nodular hyperplasia) 1 case, local adipose tissue infiltration of liver 1 case. 45 cases of contrast-enhanced ultrasonography diagnosis was consistent with pathological or clinical diagnosis. Cysts and inflammatory pseudotumour had not ultrasound contrast enhancement in the entire phase, but the crossed blood vessels was observed in inflammatory pseudotumour. The local adipose infiltration of liver had synchronous ultrasound contrast enhancement accompanied with liver tissue enhancement. 80% (12/15) of liver metastases of lack of blood supply showed fast contrast enhancement around the tumour edge and homogeneous and light contrast enhancement in the tumour center. 80 % (4/5) of liver metastases of rich of blood supply showed heavy and rapid contrast enhancement in the whole tumour. The enhancement degree in bscess and tuberculosis in the ultrasound contrast enhancement was correlated with necrosis degree, which showed fast and uneven contrast enhancement, hepatic hemangioma showed gradually contrast enhancement from its edge to center, whose enhancement time lasted for longer time than that of metastatic tumour with a statistically difference. FNH showed a typical contrast enhancement pattern, fast enhancement and fast weakening from center to edge. Hepatic cell carcinoma showed fast enhancement and fast weakening in the whole tumour. Conclusion Contrast-enhanced ultrasonography have diagnostic value of CT liver focus of low-density, which is helpful for the differential diagnosis of such focus.

The changes of zine content in serum and feces observed after intragastric administration of a certain dose of dithizone to the pregnant rats in their third trimester for one week, and the developing status of brain of their pups were studied. The result showed that the total fecal exerction of zine during 24 hours increased and serum zine content decreased significantly aftcr continual administration of dithizone for one week in maternal rats. It suggested that dithizone may be used for making animal model of zine deficiency. The body and brain weights, brain protein content and RNA/DNA ratio of the newborn delivered by the zine-deficiency maternal rats decrcased significantly. This indicates that the maternal zine dificiency in third trimester gives side effects on the development of their fctal brain.

Objective To investigate the changes of immunologic functions and life qualities after the auto-cytokine induced killer (CIK) cells combined with interleukin-2 (IL-2) being transfused back to the patients with non-small cell lung cancer (NSCLC).Methods Thirty-eight NSCLC patients were enrolled,and 19 patients received not only chemotherapy and radiotherapy but also adoptive immunotherapy with CIK cells combined with IL-2 compared with the other 19 patients who only accepted radiotherapy and chemotherapy.The changes of immunologic functions and life qualities after the CIK cells combined with IL-2 being transfused back to the patients with NSCLC were observed.Immune targets of the treatment group and control group,such as peripheral blood CD3 +,CD4 +,CD8 + T cell percentage,ratio of CD4 +/CD8 + and Th1/Th2,were observed at the end and after 3 month of the radiation and chemotherapy.Results Both of the two groups were neither having obvious adverse reactions.After CIK cells combined with IL-2 treatment,the life qualities of patients improved,such as 18 cases of mental improvement,15 cases of appetite improvement,12 cases of sleep improvement,and 3 cases of fatigue symptoms improvement.The percentage of CD3 +,CD4 + cells in the treatment group increased [(66.39 ± 9.22) ％ vs (42.98 ± 7.23) ％,t =5.45,P =0.00 ; (32.27 ± 3.75) ％ vs (26.38 ±2.51)％,t =5.73,P =0.00],the percentage of CD8 + cells declined [(17.51 ± 1.85)％ vs (20.90 ± 2.31) ％,t =5.21,P =0.00],the rate of CD4 +/CD8 + increased and the rate of Th1/Th2 obversed [(1.86±0.32) vs (1.27±0.19),t=7.13,P=0.00;(1.15±0.48) vs (0.91 ±0.30),t=2.42,P=0.02].There were significant differences between the two groups.Conclusion Adoptive immunotherapy with CIK cells combined with IL-2 is safe in clinical,which can improve the immunologic functions and life qualities of the patients with NSCLC.

Equisetin (EQST) belongs to polyketide (PKS)-nonribosomal peptide synthetase (NRPS) type compound with an inhibitory effect of 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) enzyme activity. This study investigated anti-obesity effect and insulin resistance improvement effect of EQST on high-fat diet (HFD)-induced ob/ob mice model. EQST treatment effectively reduced the body weight gain, fat weight gain and blood lipid content of model mice. All animal experiments were approved by the Medical Ethics Committee of Capital Institute of Pediatrics. EQST alleviated adipose tissue expansion and hepatic ballooning degeneration of model mice, and also effectively controlled the blood glucose content after glucose load and insulin load, showed a significant improvement in obesity and insulin resistance. EQST inhibited adipogenic proteins fatty acid-binding protein 4 (FABP4) and peroxisome proliferators-activated receptor γ (PPARγ), and upregulated thermogenic protein (uncoupling protein 1, UCP1) through suppressing 11β-HSD1 protein expression. In addition, EQST widely upregulates mitochondrial respiratory metabolism related proteins in adipose tissue and may improve insulin resistance through phosphatidylinositol-3-kinase (PI3K) pathway. Therefore, EQST plays an anti-obesity role by promoting adipose tissue thermogenesis and improving insulin resistance, which may provide reliable clues for improving obesity and diabetes.

Objective To discuss the uhrasonography and hemodynamic characteristics of carotid atherosclerosis in elderly patients with coronary heart disease (CHD).Methods The 548 people were divided into CHD group (n = 373) and control group (n = 175) by the coronary angiography.And the patients in CHD group were sorted into myocardial infarction (MI) group (n= 160) and non-MI group (n= 213).All patients were above 60 years of age, and underwent carotid artery ultrasound examination.The data of carotid sonography and hemodynamics were classified and analyzed using SPSS 10.0 software.Results The carotid intima-media thickness (IMT), plaque thickness and score were much more in CHD group than in control group [(0.96±0.24) mm vs.(0.78±0.11) mm, (1.90±0.36) mm vs.(1.66±0.13)mm, (2.2±0.7) vs.(1.9±0.4), t= 14.81, 27.89 and 27.83, all P=0.00].A total of 161 (43.2%) patients had atherosclerotie plaques in CHD group, and there were 7 (4.0%) people with plaques in healthy control group(χ~2 =337.18, P =0.00).And there were 81.3% of patients with plaques in MI group, it was more than non-MI group, in which there were 12.9% of patients with plaques (χ~2 =60.88, P=0.00).The carotid peak systolic velocity (PSV) and resistance index (RI) were both higher in CHD group than in control group [(77.0±11.9) cm/s vs.(65.2±3.1) cm/s and 0.77±0.06 vs.0.67±0.08, (t= 12.26 and 50.43, P=0.00)].Conclusions Carotid ultrasonography could evaluate not only CHD, but also CHD severity in the elderly.

Objective To study the proctective effect of heme oxygeanse-1(HO-1) on cirrhotic rats after hepatic ischemia reperfusion injury.Methods All the rats were randomly divided into 5 groups as follows: normal group(N),liver cirrhosis group(LC),sham operation group(S), ischemia reperfusion group(I/R),and I/R+hemin group.Except for N group,the other groups were injected with 40% CCl4 twice a week.After 11 weeks,the model of liver cirrhosis was formed.The segmental(70%) hepatic ischemia reperfusion operation was carried out one week later.The animals were sacrificed 6h after reperfusion.Blood was collected to measure the liver function,antioxidative ability,NF-?B and caspase-3,and HO-1 expressions were studied by immunohistochemistry method. Results Administration of hemin to induce high HO-1 expression could lessen hepatic injury,increase MnSOD enzyme level,and decrease caspase-3 and NF-?B expresssion.Conclusion HO-1 plays an important role in protecting liver cirrhosis against ischemia reperfusion injury by increasing MnSOD enzyme level and decreasing expression of caspase-3 and NF-?B.

Objective To explore the influence of allergic rhinitis (AR) on patients with systemic onset juvenile idiopathic arthritis (SoJIA).Methods The study involved 44 cases with SoJIA from Department of Pediatrics,Renji Hospital affiliated to School of Medicine of Shanghai Jiaotong University from July 2008 to November 2013.The Clinical and laboratory data of all patients were recorded respectively.This was a retrospective cohort study.According to the diagnosis of allergic rhinitis (AR),children were subdivided into AR group (16 cases) and Non-AR group (28 cases).ACR Pediatric criteria (ACR Pedi) 30/ 50/70 and related indicators of SoJIA between the two groups were compared.In the AR group,the correlation between AR scores and DAS28 was analyzed.When SoJIA of the two groups relapsed,the AR group (the treatment group) received anti-rheumatism for arthritis as well as nasal spray and oral antihistamines for AR.The non-AR group (control group) only received the anti-rheumatism for arthritis.The improvement of SoJIA between the two groups was analyzed.The continuous variables were analyzed by Student's t-test or the MannWhitney U-test as appropriate.Categorical data were compared between different groups by the Chi-square test.Correlations were determined by Pearson or Spearman's ranking.Results ① In the retrospective analysis:the physician's and patients'/parents' general assessment on a 10 cm visual-analogue scale (VAS),number of joints with res-triction of movement,number of swollen joints,ESR,serum ferritin(SF) and childhood health assessment questionnaire (CHAQ) score were significantly elevated in the AR group compared with Non-AR group at the disease onset [(6.7±1.0) cm vs (4.8±1.9) cm; (6.5±1.4) cm vs (3.2±1.5) cm; 4.1±2.7 vs 2.7± 1.7; 3.4±2.4 vs 1.4±1.5; (87±35) mm/1 h vs (61±40) mm/1 h; (888±1 043) μg/L vs (311±324) μg/L; 1.6±0.5 vs 0.7±0.3,respectively; all P＜0.05].At the 3 and 6 months follow-up after disease onset,the proportion of patients who reached ACR pedi 50,70 in AR group were lower than the Non-AR group,while the cumulative glucocorticoid dose was higher in the AR group than that of those without AR [at 3 months 38％ vs 71％; 13％ vs 46％; (76±35) mg/kg vs (43±36) mg/kg,respectively; at 6 months 25％ vs 71％; 19％ vs 64％; 127±57 vs 67±58,respectively,all P＜0.05]; In the AR group,at the disease onset,3 and 6 months follow-up after disease onset,the scores of AR was positively correlated with DAS28(r=0.741,0.703,0.680,respectively; all P＜0.05).② In the prospective study:when SoJIA was relapsed,systemic feature score,the physician's and patients' /parents' general assessment on a l0 cm VAS,number of joints with restriction of movement,number of swollen joints,ESR,SF and CHAQ score were significantly elevated in the treatment group compared with the control group [3.8±1.5 vs 2.1±1.1; (5.6±1.5) cm vs (4.5±1.6) cm; (4.6±1.9) cm vs (3.1±1.5)cm; 3.9±1.9 vs 2.5±1.4; 2.4±0.9 vs 1.5±1.2; 92±27 vs 53±37; 565(339,1 192) μg/L vs 171(85,284) μg/L; 13(0.8,1.6) vs 0.7(0.5,1); respectively; P＜0.05].The improvement rate of the physician's and patients'/parents' general assessment on a 10 cm VAS,number of swollen joints,number of joints with restriction of movement,ESR and CHAQ score at the follow-up 3 months were higher in treatment group than the control group [71(55,86)％ vs 46(0,75)％; 67(45,81)％ vs 28(-4,62)％; 92(77,96)％ vs 70(27,88)％; 65(48,81)％ vs 0(-17,67)％; 100(46,100)％ vs 42(0,100)％; 67(49,85)％ vs 37(0,75)％; P＜0.05].At the follow-up 6 months,the improvement rate of ESR,patients'/ parents' general assessment on a 10 cm VAS,number of joints with restriction of movement and CHAQ score were higher than control group [94(85,96)％ vs 73(33,85)％; 89(65,99)％ vs 63(5,85)％; 100(100,100)％ vs 100(0,100)％; 91(69,100)％ vs 72(11,91)％; respectively,P＜0.05].Conclusion AR may exert an adverse influence on SoJIA.SoJIA patients who are treated with combined with AR may have better outcome than those who are only treated for arthritis.

Objective To investigate the expression and significance of Smad4 and Smad7 in newborn rats with hyperoxia-induced chronic lung disease(CLD).Methods Sixty-four newborn Wistar rats 12 h after birth were divided into high-oxygen group (n =32) and air group (n =32,control group) by random number table method.The high-oxygen group was placed in the oxygen glass tank with continuous infusion of oxygen.And 1,3,7,14 d after experiment,tracheal separated,the chest opened to expose heart and lung,slices were Masson staining,undergo dynamic observation of the pulmonary pathological changes under light microscope.Lung fibrosis score was carried out to determine the degree of pulmonary fibrosis,and immunohistochemical technique was used to detect Smad4 and Smad7 protein expression in lung tissue.The expression levels of Smad4 and Smad7 protein in lung tissue were detected with Western blot.Results Compared with the air group,there was statistically significant difference in pulmonary fibrosis score on day 7 (2.67 ± 0.21 vs 0.58 ± 0.17) and day 14 (4.48 ± 0.24 vs 0.63 ± 0.13) in high-oxygen group (P ＜ 0.05) ; Smad4 and Smad7 was main in visible lung epithelial cells and interstitial fibroblasts.Smad4 expression in the high-oxygen group gradually enhanced,compared with the air group (P ＜ 0.05) on day 7 (122.35 ± 10.3 vs 140.08 ±7.77) and day 14(129.7 ± 7.33 vs 144.99 ± 6.49).Smad7 expression in the high-oxygen group first increased and then decreased,expression in the high-oxygen group increased on day 7 (122.35 ± 10.29 vs 130.56 ±9.8),and compared decreased with the air group(P ＜0.05) on day 14(132.16 ±4.38 vs 126.22 ±6.49).Conclusion The newborn rat exposed hyperoxia,the up-regulation of Smad4 protein expression and the down-regulation of Smad7 protein expression are imposible closely related to the happen and development of CLD pulmonary fibrosis.
