Objective To investigate the influence of IVIG on immunologic function and cytokines levels in children with EV71 infection associated high-risk pulmonary hemorrhage. Methods According to the inclu-sion criteria , 64 children were enrolled and randomly divided into two groups: 39 cases in the IVIG treatment group and 25 cases in the general treatment group. The alternations of blood and immune cytokine markers before and after treatment were detected in the patients. Results (1) Before treatment, the peripheral blood T cells, TH and B cells in the IVIG group were higher than those in the general group , but the peripheral blood IgA was lower than that in the general group(P < 0.05); (2) In the IVIG group, the NK cells and IgG increased and T cells, TH cell and B cells significantly decreased after receiving IVIG therapy (P < 0.05); (3)No significant difference was observed in the levels of IL-6 and IL-10 in the two treatment groups before treatment. However , after IVIG treatment, IL-6 and IFN-γ levels reduced, IL-10 level increased (P < 0.05). After the general treat-ment, no significant difference was found in levels of IL-6,IL-10 and IFN-γ in peripheral blood (P > 0.05). Conclusion Disorders of cellular immunity and humoral immunity appeared in children with EV71 infection-re-lated high-risk pulmonary hemorrhage. It has clinical value to use IVIG timely to regulate the immune disorder.

BACKGROUND:Knowledge of retropedtoneal space communications might influence catheter placement,and understanding the normal anatomy of the retroperitoneal space is a prerequisite for predicting the distribution of inflammation or other fluid collections in this region. Until recent years,the media/ attachment of the posterior renal fascia remained controversial. The multiple detector spiral CT can show the abdominal anatomic details. So,using the multiple-detector spiral CT to study the anatomy of posterior renal fascia has clinical significance. OBJECTIVE:To describe the medial attachment of the posterior renal fascia by using multiple-detector spiral CT. DESIGN,TIME AND SETTING:A retrospective case analysis was performed at Department of Radiology,Affiliated Hospital of Weifang Medical College between June 2003 and November 2007. PARTICIPANTS:A total of 52 patients with retropedtoneal inflammatory diseases were retrospectively reviewed through analysis of their CT data. METHODS:Toshiba Akuilion 16-detector spiral CT was employed for scanning. Of the 52 patients,15 were proved by clinical and laboratory findings and 37 were proved by surgery and pathology. Among the 52 patients,17 suffered from appendicitis,1 from ureteritis,2 from abscesses in the perirenal space,3 from abscesses in the posterior pararenal space,and 29 from pancreatltis. MAIN OUTCOME MEASURES:Medial attachment of the bilateral posterior renal fascia. RESULTS:At the level of the upper pole of kidney,the posterior renal fascia fused with the fascia of the ipsilateral quadratus lumborum muscle. Forty-six patients manifested the attachment site of the left posterior renal fascia transforming from the quadratus lumborum muscle fasciae to the psoas major muscle fascia at the level of the lower pole of kidney or the infrarenal space. Fifty patients showed the attachment site of the right posterior renal fascia transforming from the quadratus lumborum muscle fascia to the psoas major muscle fascia at the level of the lower pole of kidney or the infrarenal space. CONCLUSION:The posterior renal fascia attachment site is not the same all the time. At different levels,the attachment site of the posterior renal fascia is distinct.

The experiment was conducted to examine the effect of zinc toxicity on the peripheral blood T-lymphocyte by the method of flow cytometry(FCM) and ANAE.200 one-day-old Avian broilers were divided into four groups,and fed with the diets as follows:①control group(Zn 100 mg/kg diet) and ② zinc toxic groups(Zn 1 500 mg/kg diet,zinc toxic group Ⅰ;Zn 2 000 mg/kg diet,zinc toxic group Ⅱ;Zn 2 500 mg/kg diet,zinc toxic group Ⅲ) for seven weeks.The ANAE positive ratios of the peripheral blood T-lymphocytes were much lower in the three zinc toxic groups than that in control group at 7 weeks of age.CD4+ T cell numbers were reduced from 2 to 7 weekds of age in zinc toxic group Ⅲ and from 6 to 7 weeks of age in zinc toxic group Ⅱ,as compared with that of control group.The numbers of CD8+ T cell decreased at 2 and 4 weeks of age in zinc toxic groups Ⅱ and Ⅲ,and at 7 weeks of age in zinc grups Ⅰ and Ⅲ.CD4+/CD8+ ratio was higher at 2 and 4 weeks age,and lower at 6 and 7 weeks of age in zinc toxic groups Ⅰ,Ⅱ and Ⅲ than in control group.The results showed that zinc toxicity would suppress the development of T-lymphocytes and reduce the peripheral blood T-lymphocyte populations.Potential mechanism underlying these observations are also discussed.

The experiment was conducted to examine the effect of copper toxicity on the peripheral blood T-lymphocyte using the flow cytometry(FCM) and ANAE.180 one-day-old Avian broilers were divided randomly into three groups,and fed diets as follows:(1)Controls(Cu 11.97 mg/kg diet) and (2)copper toxic(Cu 650 mg/kg diet,copper toxic group Ⅰ;Cu 850 mg/kg diet,copper toxic group Ⅱ) for six weeks.The ANAE positive ratios of the peripheral blood T-lymphocytes were much lower in the two copper toxic groups than in control group from 1 to 6 weeks of age(P＜0.05 or P＜0.01).Also,there was significant difference between copper toxic groups Ⅰ and Ⅱ at 1,3,5 and 6 weeks of age(P＜0.05 or P＜0.01).CD+4 T cell numbers reduced from 2 to 6 weeks of age in both copper toxic group Ⅰ and copper toxic group Ⅱ as compared with those of control group(P＜0.05 or P＜0.01).At the same time,there was significant difference between copper toxic groups Ⅰ and Ⅱ at 6 weeks of age(P＜0.05).But the numbers of CD+8 T cell were not varied from 2 to 6 weeks of age in copper toxic groups Ⅰ and Ⅱ in comparison with those of control group(P＞0.05).The CD+4/CD+8 ratio was lower from 2 to 6 weeks of age in copper toxic groups Ⅰ and Ⅱ than in control group.The results showed that copper toxicity could suppress the development of T-lymphocytes and reduce the peripheral blood T-lymphocyte populations.Potential mechanisms underlying these observations are also discussed.

Objective To research whether the inhibitory oligonucleotides could improve the immune status of the BXSB mice. The purpose was to provide a valuable direction for treating systemic lupus erythematosus. Methods 3-month-old BXSB lupus mice were divided into three groups (including inhibitory oligonucleotides group, saline group and blank control group). The 24 hours urine proteins were determined before treatment. After treatment,the urine protein, anti-dsDNA, peripheral blood lymphocytes apoptosis and immune complex in renal glomeruli were measured. Results Before treatment,the urine proteins had no statistical differences among the three groups ( P > 0.05 ).After treatment,the urine protein, anti-dsDNA levels in inhibitory oligonucleotides group were significantly lower than that of control group(P < 0.01 ). Apoptosis of peripheral blood lymphocytes in inhibitory oligonucleotides group was significantly higher than that of control group( P < 0.05 ) ,immune complex in renal glomeruli in inhibitory oligonucleotides group was significantly lower than that of the other groups ( P < 0.05 ). Compared with saline group, inhibitory oligonucleotides had prolonged life period of BXSB mice ( P < 0.01 ). Conclusion The inhibitory oligonucleotides could improve immune status of BXSB, and could put off the disease progression.
