Circulating cell-free nucleic acids are defined as extracellular DNAs or RNAs in blood with physiological or pathological origins. Previous studies showed that the concentration of cell-free nucleic acids in the blood of cancer patients is significantly higher than in healthy people. Further studies showed that the genetic and epigenetic alterations of circulating cell-free nucleic acids are relevant to cancer development and progression, including mutation, hypermethylation, loss of heterozygosity, change of integrity, and abnormal expression of microRNAs. Detection of circulating cell-free nucleic acids shows promising potential in cancer screening, diagnosis, personalized treatment, and prognosis.

Objective To evaluate male bulbourethral sling procedure for the treatment of post prostatectomy urinary incontinence. Methods 7 male patients with severe post prostatectomy incontinence underwent the male bulbourethral sling procedure,the patients being completely incontinent before treatment. Results The patients have been followed up for 14~26 months with a mean of 20.Ideal continence has been achieved in 6 and significantly improved in 1. Conclusions Bulbourethral sling procedure is effective for post radical prostatectomy and intrinsic sphincter deficiency urinary incontinence.

AIM: To observe the effect of Jianpixiaoshi Pill (Rhizoma Atractylodis Macrocephalae, Fructus Aurantii Immaturus, Radix Aucklandiae, etc.) METHODS: We conducted the humoral immunity test, intestine peristal sis test, gastric emptying test, gastric analysis test on rat's and mouse's mode ls of splee n weak by oral administration of Rhubarb root lard and cabbag e, respectively. RESULTS: On mice fed on Rhubarb root, Jianpixiaoshi i Pill can effectively potentiate immunity, improve the velocity of stomach and intestine, expedite the advance speed of ink in the small intestine and the velo city of gastric emptying, reduce the residual rate of methyl orange in stomach. On rats fed on lard and cabbage, J ianpixiaoshi Pill can gain mouse's weight improved, increase the total acidity of the gastric juice and the activity of pepsin. CONCLUSION: Jiah pixiaoship Pill has remarkable effect on improvin g the function of intestine and stomach.

Objective To investigate the methods and effects of anterolateral thigh flap reconstruction of the complicated hip decubitus.Methods The study contained 24 cases of grade Ⅳ hip decubitus reconstructed with anterograde pedicled anterolateral thigh flaps through May 2010 to July 2014.There were 13 males and 11 females,aged 26-64 years (mean 54 years).Defects ranged in size from 12 cm×6 cm to 24 cm× 12 cm.Dimensions of flaps harvested were 14 cm ×8 cm to 30 cm× 14 cm.Eighteen cases of the donor sites were directly sutured and six covered with full thickness skin.Results Twenty-two flaps survived completely,and wound was healed by the first intension.Two flaps developed partial distal necrosis,and wound was healed after dressing treatment.Period of follow-up was 6 months to 2 years.Shape,texture and color of the flaps were well matched with the recipient area.Conclusion The anterolateral thigh flap transplantation has advantages of similarity to the recipient area,large enough flap area and sound expected effective and is a good method for repair of hip decubitus.

Objective To explore the effect of hepatitis B virus(HBV) on the expression of complement 3 (C3) and complement 4 (C4) and its regulatory mechanism.Methods Differentially expressed genes between HepG2 and HepG2.2.15 cells was screened by gene chip,serum complement component 3 (C3) and 4 (C4) levels in patients with HBV infection and in healthy individuals were measured by Immunoturbidimetry,HBV infectious clone pHBV1.3 was transfected into HepG2 cells,and expression of C3 and C4 was measured by RT-PCR and Western blot.Results Expression of C3 and C4 mRNA was lower in HepG2.2.15 cells than in HepG2 cells,serum C3 and C4 levels was much lower in patients with chronic hepatitis B and hepatic carcinoma as compared to healthy individuals (P<0.05 ).HBV could downregulate the expression of C3 and C4 at mRNA and protein levels.Conclusion HBV may inhibit the expression both in vivo and in vitro.

Porcine circovirus type 2 (PCV2) can cause immunosuppression on herds. PCV2, as an essential pathogen of PCV2-systemic disease (PCV2-SD), has caused considerable economic losses in pig industry worldwide. Here we review and address the evolution, viral protein and immunolesion of PCV2 and preventive techniques of PCV2-SD.

Objective To investigate the research quality of present medical graduates and propose suggestions for improvement.Method A self-designed questionnaire entitled Investigating Questionnaire for Research Quality Analysis of Medical Graduates in Peking Union Medical College Hospital was distributed to the clinical and academic medical graduates in the hospital from July to August 2015.Among 276 collected questionnaires,270 were validated as effective.SPSS 18.0 software was used to statistically describe the result and to perform t test on different subgroups.Results The research quality average of the surveyed hospital was 10.28.Results revealed that in regard of the three aspects of research quality,research consciousness ranked first,followed by the research ability,while scientific spirit was the weakest.Academic medical graduates showed significantly higher scores than clinical graduates in terms of total research quality and every single aspect (P values less than 0.05).Conclusions To better cultivate the academic leaders in medical research,it is necessary to strengthen the research training for the graduates,practice their scientific thinking especially the clinical graduates,reinforce tutors' guidance,and promote communication and collaboration.
