Objective To estimate the association of the single nucleotide polymorphism (SNP) and the serum concentration of interleukin (IL)-18 with ulcerative colitis (UC) . Methods Samples collected from 50 patients with UC and 128 healthy controls were detected for SNPs of IL-18 gene including rs187238, rs5744228, rs360718 and rs360717 using polymerase chain reaction (PCR) and direct sequencing. Meanwhile, the serum level of IL-18 was measured. ResultsSerum concentration of IL-18 was higher in patients with UC than in healthy controls [(3029.9±111.7) pg/ml vs ( 133.2±39.4) pg/ml,(P<0.01)], rs187238 C, rs360718 C and rs360717 A were significantly related to UC (X~2=9.26, P<0.01). There was significant difference in frequencies of rs187238 C, rs360718 C and rs360717 A between patients with UC and healthy controls (X~2=9.26, P<0. 01). Serum concentration of IL-18 was higher in UC patients with C allele than in healthy controls (P<0.05).Conclusions There is correlation between SNP and serum level of IL-18 , which may involve in susceptibility to UC.

?Objective:To study the influence of composite Danshen droplet pills on hemorheology in peripheral blood of patients with oral lichen planus (OLP).Methods:46 patients with OLP were treated by composite Danshen droplet pills for 8 weeks (oral administration,3 times/day,10 granules/time).The venous blood was taken and the hemorheology was studied with a LBY N6A hemorheology test machine before and after the treatment.Results:Effective results were observed in 33 patient and obvious effective results in 5,while no treating effect was found in 8 after treatment.Whole blood viscosity,blood plasm viscosity,erythrocyte aggregation indexs,thrombocyte aggregation rate,fibrinogen and ESR of the OLP patients were decreased ( P 0.05).Conclusion:The composite Danshen droplet pills may improve the hemorheology of OLP patients.

Object To provide a basis for the identification and quality control of the crud drugs of Costus L.. Methods Morphological and histological characters of the rhizomes of Costus spectosus (Koen.) Smith, Costus lacerus Gagnep.and Costus tonkinensis Gagnep. were described and illustrated, respectively. TLC of the above drugs was finished. Microscopical characters of the epidemis of leaves of these species were also compared. Results The characters involving the vessel order in vascular bundle ring at the inner side of pericycle in the transverse section, calcium oxalate crystals occurred in the vessel, the characteristic calcium oxalate crystals in the cortex and cork cell and the TLC qualitative analysis for diosgenin, etc. are important for identification of Costus L.. Conclusion These three crude drugs can be identified by the above research results.

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.

Objective To observe the expression of cysteine rich-protein 61 (Cyr61) on renal tubular cells,to explore its effects against hypoxic induced kidney injury and the underlying mechanisms.Methods A stably Cyr61 expressed tubular cell line Cyr61-HK2 was established based on HK2 cells and recombinant Cyr61-lentivirus.BrdU incorporation assay was used for cell proliferation.The apoptosis of cells was analyzed by flow cytometry with Annexin V and propidiumiodide staining.Western bloting was used to detect the protein expression of BAD,Akt and ERK.Results (1) Cyr61-HK2 cells displayed more proliferation ability than HK2 cells.(2) Under hypoxia condition,the apoptosis of both HK2 and Cyr61-HK2 cells increased,but the apoptosis of Cyr61-HK2 cells was lesser than HK2 cells.(3) The expression of Cyr61 led to the phosphorylation of BAD,Akt and ERK on 0 h,0.5 h,1 h (all P ＜ 0.05).Conclusion The expression of Cyr61 can promote cell proliferation and dampen cell apoptosis induced by hypoxia,which may be involved in the Akt/ERK signal pathway.

Objective To determine whether mutation of Hepatitis B virus (HBV) X gene is associated with hepatitis B virus-associated glomerulonephritis (HBV-GN).Methods The venous blood was collected from 50 patients with HBV-GN and 60 patients with asymptomatic HBV carriers (control group).Serum HBV DNA was extracted to determine the serum titer of HBV-DNA and then polymerase chain reaction (PCR) was used to detect the HBV X gene mutation.Results (1)There were not statistical significance between age and gender in HBV-GN group and control group (P ＞0.05).There were not statistical significance of serum replication level of HBV DNA in HBV-GN with X gene mutation and control group (P ＞ 0.05).Urine protein excretion in HBV-GN group with or without X gene mutation was found with statistical significance (P ＜ 0.05).(2)Nucleotide mutations [84％ (42/50)] resulted in amino acid substitution in HBV-GN.Nucleotide mutations changed in transfunction control region of X gene,including position nt1653,nt1726,nt1727,nt1730,nt1753,nt1762 and nt1764.(3)Nucleotide mutations [8％(5/60)] resulted in amino acid substitution in control group.Nucleotide mutations changed in position nt1632 and nt1635,located in non-functional region.Conclusions HBV X gene mutations and the subsequent amino acid substitutions are found in HBV-GN.The urine protein excretion level increases in patients with X mutation,suggesting that these mutations may play an important role in the pathogenesis of HBV-GN.
