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.

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 study the release characteristics of Evening primrose oil microspheres in vitro. METHODS:UV spectrophotometry was adopted to determine the accumulated release of microspheres under different media,and the drug release behaviors in vitro were fitted using zero-order,first-order and Higuchi equations.

CONCLUSION:This method is simple,accurate and reproducible,and it can be used for the determination of the release rate of the Evening primrose oil microspheres.

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.

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: An automatic seamless stitching method with spinal X-ray image sequence is presented in this paper. Methods: First, biorthogonal wavelet transform is used to implement decomposing of the multi-resolution and the effective edge of the image can be extracted by this method combined with Canny operator. The feature points of the image can be obtained by calculating the edge contour matrix E and the value matrix H. Second, the roughly matching of feature points can be achieved by using Normalized Cross Correlation (NCC) algorithm and the random sample consensus (RANSAC) algorithm is introduced to remove false matching pairs and to achieve precisely matching. Third, the image sequence is automatically sorted with the improved genetic algorithm to achieve automatic stitching. At last, the weighted average fusion algorithm is appfied to achieve smooth and seamless image stitching. This algorithm is robust for the weak-contrast X-ray image sequence. Results: Experimental results show that high-quality and fast image sequence stitching can be obtained automatically by using this method. Conclusions: To a certain extent, it overcomes the shortcomings of X-ray image sequence such as the strong image noise, concentration of values ofpixels, blurred boundaries, large overlap area and the sequence constraint, and therefore it may be applied to in medical imaging field widely.

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.
