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.

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 prepare and evaluate the reference materials for plasma von Willebrand Factor antigen testing with fresh frozen plasma.Methods The candidates were prepared by low temperature centrifugation in 5 different concentration levels.The homogeneity and stability of the preparation was evaluated according to the ISO Guide35 and CNAS-GL03.The comparability between STAGO and IL system was evaluated according to the WS/T 356-2011.Then the preparations were characterized by six laboratories with the Secondary Coagulation Standard established by NIBSC(SSCLOT4).Results Homogeneity evaluation of the preparation showed that there was no statistically significant difference between the groups (P >0.05),the F values of factor analysis of variance were 0.317~0.844,the uncertainty range was 1.01% ~2.06%.A linear regression based on stability evaluation indicated that the linear trend (within 24 weeks)was insignificant (P >0.05). The uncertainty range of long-term (within 24 weeks)stability was 0.79% ~ 1.20%.The results of the preparations on STAGO and IL system were comparable.The certificated values of the candidates were range from 12.2% to 138.9% with uncertainties were 0.06%~0.09%,respectively.The range of combined standard uncertainty was 0.03% ~ 0.16% while the expanded uncertainty was 2.2%~6.7%.Conclusion The reference materials for von Willebrand Factor antigen testing were stable and homogenous with comparability between STAGO and IL.The method of characterization was accurate and reliable.

Objective To improve the knowledge,diagnostic level on concealed penis in children,and explore the operative treatment methods of concealed penis.Methods Ten children with concealed penis were reviewed retrospectively in the First Hospital of Jilin University from Jun.2005 to Jul.2007.Patients were 6-12 years old.Penis length was 1.2-2.6 cm.Patients growthing and micturition were normal,the results of androgne and estrogen examination were normal.The etiology was simple obesity in one case,fiber streak of penis sarcolemma in 9 cases.The clinical symptoms and signs,diagnosis and operative method were analyzed.Results The diagnosis of 10 children were correct,and all patients were treated by Devine's operation and 10 cases patients had healed in one stage.There was no vessel,nerve and urethra injury during the operation.The length of penis was 3.0-5.5 cm,average in 3.6 cm after operation.Followed up 3 months to 2 years,10 children's phimosis were removed,the micturition were normal;the appearance of penis was also satisfactory after operation.One patient with under-developed penis had a amelioration after treatment with HCG postoperatively.The penis contour was dissatisfactory in 1 obesity patient,but it was ameliorated gradually while growing up.Conclusions The correct diagnosis and differential diagnosis are very important for operative treatment depend on the different etiology and pathologic changes of concealed penis.Suitable operation can extend the length;moreover,ameliorate the symptom of micturition and the appearance of the penis.

OBJECTIVE:To know the residual characteristics of organochlorine pesticides and 5 kinds of heavy metals (Cu, As,Cd,Hg and Pb) in Panax notoginseng. METHODS:P. notoginseng samples with 3 years were collected from Baiyi Town, Songming County and Liushao Township,Xundian County of Yunnan Province in Apr. 2013. 60 strains of P. notoginseng and 1 kg rhizosphere soil samples were also collected. The organochlorine pesticide residues and 5 kinds of heavy metals on its various parts and soil samples were detected. Pesticide residues determination method in Chinese Pharmacopoeia(2010 edition,volumeⅠ)was conducted to determine the organochlorine pesticides and 5 kinds of heavy metals (Cu,As,Cd,Hg and Pb). RESULTS:There was pentachloronitrobenzene in different parts of P. notoginseng from Baiyi Town,Songming County,and the contents were root bark>fibrous≥notches>ribs>leaves;there were pentachloronitrobenzene only in the root bark and fibrous of P. notoginseng from Liushao Township,Xundian County,and the contents were root bark>fibrous. No Hg was detected in any part of P. notoginseng samples,and the other heavy metals were highest in root bark;As and Pb were relatively high in soil,the contents of As and Pb in samples were far lower than in soil. CONCLUSIONS:The contents of pesticide residues and heavy metals in different parts of P. notoginseng are different,and those in root bark are relatively high. P. notoginseng sample contains organochlorine pesticides, which is mainly pentachloronitrobenzene;P. notoginseng sample has relatively strong accumulation of Cd.
