Objective To study the influence of partial internal sphincterotomy on the postoperative pain after cutting seton treatment in patients with perianal infection. Methods A controlled study was carried out on 40 cases of cutting seton insertion with (Group A) or without (Group B) partial internal sphincterotomy. The subjects reported their postoperative pain at defecation and at rest respectively using a visual analogue scale (VAS). The intensity of pain between the two groups was compared. Results All the 40 patients were cured, without recurrence or fecal incontinence. During the period of cutting seton treatment, the pain scores at defecation and at rest were lower in the Group A than in the Group B ( P 0.05). Conclusions Internal sphincterotomy can significantly relieve anal pain after cutting seton treatment, being an effective method.

Objective To investigate the relationship between chronic prostatitis (CP) and male infertility. Methods 120 cases of male infertility patients with chronic prostatitis and 120 cases of male infertility patients with-out chronic prostatitis were analyzed. Results The differences of sperm quality、sperm movement function, partial bio-chemical indicator in semen and sperm aggregation in the two groups are significant (P<0.05). Conclusion CP plays an important negative role in male infertility.

Objective MicroRNAs (miRNAs) are endogenous short stranded RNAs with a length of about 22 NT, which are highly conserved and have no coding function.Mature miRNAs play a role by specifically binding to the 3′untranslated region of the target gene, degrading the mRNA of the gene or hindering its translation at the post transcriptional level, so as to negatively regulate the expression of the target gene and play a biological role.In recent years, the research of miRNAs in cardiovascular diseases is increasingly in-depth.A large number of evidences show that miRNAs play a role in the pathogenesis of many cardiovascular diseases, and will become a potential marker and new treatment target for the diagnosis and prognosis evaluation of cardiovascular diseases.

Objective To detect the expression of interleukin (IL)-18 of the peripheral blood cells and IL-18 receptor α chain(IL-18Rα) on the surface of CD_3~+ cells in patients newly diagnosed as immune thrombocytopenia (ITP) before medication and to explore the roles of IL-18 and IL-18Rα in the development of ITP. Methods Eighteen out-patients or inpatients with acute ITP accepting treatment in Qilu Hospital were enrolled in this study and 15 matching healthy subjects were taken as control. Plasma IL-18 level was detected with enzyme linked immunosorbent assay (ELISA), the expression of IL-18Rα on CD_3~+ lymphocytes and total lymphoeytes were measured with flow cytometry; T-bet and GATA-3 mRNA were measured with reverse transcriptase polymcrase chain reaction (RT-PCR). Results The expression of IL-18 in acute ITP plasma was (468. 57 ± 141.62) ng/L and IL-18Rα on the surface of CD_3~+ cells and lymphocytes were (8.50 ±3. 16)% and (9. 16±2.98)% respectively. The levels of IL-18 and IL-18Rα were increased in active ITP patients as compared with those in the controls (P <0. 05). The levels of IL-18 mRNA (0. 12 ±0. 02) and T-bet mRNA (0. 07 ±0. 02) were significantly increased in patients with active ITP as compared with those in the controls (P <0.05), while GATA-3 mRNA (0.0039±0.0014) were significantly decreased in patients with active ITP (P < 0. 05). The balance between T-bet and GATA-3 was significantly disturbed in ITP. Conclusions Through the variation of the levels of gene and protein, our study showed that IL-18 and IL-18Rα might upregulate the expression of Th1-cytokines in ITP patients. It is also suggested that IL-18 has potential association with the development of ITP. Especially, it may provide a new treatment method for ITP by regulating the ratio of T-bet and GATA-3 and resuming the balance of Th1/ Th2.
