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 explore the relationship between expressions of C-type lectin receptors on natural killer(NK) cells and infant human cytomegalovirus (HCMV) infection. Methods Seventynine cases of HCMV infection infants and 39 cases of HCMV non-infection control infants admitted during January 2006 to June 2008 were recruited in this study. According to HCMV pp65 antigenemia levels in the peripheral blood, 79 cases of HCMV infection infants were divided into two groups: 48cases of active HCMV infection and 31 cases of inactive HCMV infection. The 48 cases of infants with active HCMV infection were treated with ganciclovir for 2 weeks. The expressions of NKG2A,NKG2C, and NKG2D receptors on NK cells in the peripheral blood were examined by flow cytometry.Data analysis was done using SPSS 17.0 software. Comparisons among 3 groups were performed by Kruskal-Wallis nonparametric test for independent samples and comparisons between groups were done by Mann-Whiteney nonparametric test for paired samples. Results There was no difference of the inhibitory receptor NKG2A expression on NK cells among groups of active HCMV infection, inactive HCMV infection and HCMV non-infection controls (x2 = 3. 95, P＞0. 05). However, there was obvious difference of activating receptors of NKG2C and NKG2D expressions on NK cells among the three groups (x2 =24.91 and x2 =47. 80, respectively; both P＜0.01). The expressions of NKG2C and NKG2D on NK cells in the HCMV infection group were both higher than the control group (Z=-4.72 and Z=-5.15, respectively; both P＜0.01). The expression of NKG2D on NK cells in the active HCMV infection group was higher than that in the inactive HCMV infection group (Z= -5.08,P＜0.01). The expression of NKG2D on NK cells decreased after ganciclovir treatment (Z= - 1.34,P=0. 07). Conclusion Expressions of NKG2C and NKG2D on NK cells might play a significant role in regulating NK cell function and anti-HCMV immunity in infants.

Objective　To investigate the prognosis in risk of ventricular arrhythmia in coronary heart disease with heart rate variability (H RV), left ventricular ejection fraction (LVEF) and other clinical background dat a. Methods　A total of 81 patients were divided into ventricular premature beats (VPBs)≥30/h group and VPBs<30/h group. Their LVEF, HRV and cli nical data were studied and analyzed. Results　The age and blood pressure between 2 groups had no significant difference. LVEF, standard deviati on of all normal RR intervals (SDNN), SD of the average of NN interval (SDANN) a nd HRV triangular index (HRVI) were significant less in VPBs≥30/h group than in VPBs<30/h group (43.29±15.38 vs 67.33±11.47，P＜0.01；90.05±22.2 9 vs 117.90±30.32，P＜0.05；77.43±17.78 vs 105.69±28.79，P＜0.05 ；24.54±8.70 vs 32.70±10.87，P＜0.05, respectively). Incidence of myo cardial infarction (MI) was larger in VPBs≥30/h group than VPBs<30/h group. LVE F was the independent predictable factor in risk of ventricular arrhythmia with multinomial regression logistic analysis（B=0.119, P=0.032）. Co nclusion 　Our findings indicate that LVEF is an independent predictable factor i n risk of ventricular arrhythmia in coronary heart disease. Although HRV and MI history can not be used to predict VPB, significant difference is found between 2 groups. High-risk patients could be selected successfully when these data are considered in combination.

Objective To evaluate the inlluence of atopy on juvenile idiopathic arthritis (JIA).Methods The study involved 117 cases with JIA from Department of Pediatrics,Renji Hospital Affiliated to School of Medicine of Shanghai Jiaotong University from Jul.2008 to Jul.2013.These patients were enrolled for retrospective cohort study,and subdivided into JIA and atopic group or JIA and non-atopic group.There were 34 cases combined with atopy,83 cases without atopy.Based on the diagnosis of allergic rhinitis (AR),those JIA children in the atopic group were organized into AR group (19 cases) and non-AR group (15 cases).The clinical and laboratory data were recorded and analyzed to compare the differences of the remission of American College of Rheumatology Pediatric (ACR Pedi) 30/50/70 between atopic group and non-atopic group,AR group and non-AR group.In AR group,the correlation between AR scores and disease activity score (DAS28) was analyzed.Results 1.The physician's and patients'/parents' general assessment on a 100 mm visual-analogue scale (VAS),number of joints with restriction of movement and childhood health assessment questionnaire (CHAQ) were significantly elevated in atopic group compared with controls at the beginning (all P ＜ 0.05).In the follow-up 3 months after disease onset,the proportion of reaching ACR Pedi 30,50 and the proportion of reaching ACR Pedi 50,70 in 6 months later in JIA with atopy were lower than JIA children without atopy (all P ＜ 0.05) ; In the follow-up 3 and 6 months,the cumulative glucocorticoid dose was higher in atopy group compared with Non-atopy,which showed a statistical significance (all P ＜ 0.05).2.Among the AR group,at the disease onset,the physician's and patients'/parents' VAS,number of joints with restriction of movement and CHAQ were elevated in AR group compared with controls with statistical significance (all P ＜ 0.05).In the follow-up 3 months,the proportion of reaching ACR Pedi 30 and 50 was lower in AR group compared with non-AR group.In the follow-up 6 months,the cumulative glucocorticoid dose was higher in AR group compared with non-AR,which showed a statistical significance.But the ratio of ACR Pedi 30,50 and 70 were lower in AR group compared with non-AR group (all P ＜ 0.05).Among JIA combined with AR,at the beginning,follow-up 3 and 6 months after disease onset,the scores of AR positively correlated with DAS28 (r =0.671,0.518,0.496,all P ＜ 0.05).Conclusion Atopy or AR may exert an adverse influence on JIA.

Objective: To study the effect of casein hydrolysate (CH) on hypertensive rats. Method: Hydrolysate of casein was desalinated by macroporous adsorption resins DA201C. Angiotensin converting enzyme (ACE) inhibitory activity and antihypertensive activity of casein hydrolysate at the dose of 500, 1 000 mg/kg were measured. Results: CH had significant inhibitory activity against ACE (the inhibitory rate 80.1%), and low concentration (500 mg/kg bw?d) had remarkable antihypertensive activity on spontaneously hypertensive rats (SHR), and extremely remarkable at high concentration (1 000 mg/kg bw?d). Conclusion: Casein hydrolysate showed antihypertensive activity in SHR.

Objective To explore the upper bound of Ⅱb region in the clinical target volume ( CTV ) for intensity?modulated radiotherapy ( IMRT ) for nasopharyngeal carcinoma ( NPC ) , and to establish a standard for personalized reduction in the range ofⅡb region. Methods A retrospective analysis was performed on the IMRT results of 142 patients newly diagnosed with NPC who were admitted to our hospital from 2012 to 2014. According to the American Joint Committee on Cancer 2010 staging system, there were 8 patients with stageⅠ disease, 37 stage Ⅱ, 41 stage Ⅲ, and 56 stage Ⅳ. The distribution pattern of cervical lymph nodes in NPC was studied based on the imaging results. Comparison of the dose to parotid glands between patients with and without reduction in the range ofⅡb region was made by t test and t'test. Results The metastasis rates of the most common diseased lymph nodes, lateral retropharyngeal lymph node and Ⅱb lymph node, were 75?4% and 67?6%, respectively. In the patients with metastases inⅡb region, 51?0% had high?risk positive lymph nodes and 6?3% had positive lymph nodes beyond the upper bound of Ⅱb region defined by the Radiation Therapy Oncology Group system. It was safe to narrow down Ⅱb region in patients who met the formulated standard. The D50 and V26 values for parotid glands were significantly reduced after optimization of CTV ( P=0?000) . Conclusions The upper bound ofⅡb region, in principle, should reach the lateral skull base during the delineation of the cervical CTV for NPC. In order to protect the parotid glands, however, personalized reduction in the upper bound of Ⅱb region is recommended for patients who meet the formulated standard.
