OBJECTIVETo improve the methods and reduce the complications of circumcision with a disposable suture device.

METHODSThis study included 325 male patients aged 14-65 (mean 28.9) years, treated for redundant prepuce or phimosis by modified (n = 201) or conventional circumcision with a disposable suture device (n = 124). We compared the incidence of complications and the patients' satisfaction between the two surgical methods.

RESULTSCompared with conventional circumcision, the modified method showed a significantly lower incidence of postoperative bleeding (14.52% vs 2.49% , P < 0.05) and a lower rate of second surgery for penile hematoma (4.03% vs 0.50%, P < 0.05). The patients' satisfaction was markedly higher with the modified method (91.94%) than with conventional circumcision (97.51%) (P < 0.05).

CONCLUSIONModified circumcision with the disposable suture device can significantly reduce the incidence of postoperative bleeding and penile hematoma and therefore deserves wide clinical application.

Objective To investigate the difference of the protein expression in serum of rats with acute edematous pancreatitis (AEP) and acute necrotizing pancreatitis (ANP),and to investigate serum marker for acute pancreatitis severity.Methods The model of AEP and ANP was induced by retrograde injection of 4％ or 5％ sodium taurocholate into the biliopancreatic duct.Weak cation exchange (WCX2) and surface enhanced laser desorption/ionization time of flight mass spectrometry ( SELDI TOF MS) was used to investigate the difference of the protein expression in serum of rats with AEP and ANP.Results Thirty-eight spectral peak clusters which had significantly different signal intensities between AEP and ANP sera at mass charge ratio between 1000-50 000(P ＜0.05) were detected.The peak clusters at 9500 and 9700 in the sera of AEP were higher than that in ANP rata.Conclusions Serum analysis with SELDI-TOF MS can detect the difference of the protein expression in rats with AEP and ANP.The decreased expression of the protein of molecular weight of 9500 and 9700 may be a signal of AEP transition into ANP.

Glioblastoma(GBM)is one of the most common primary intracranial tumor that has high de-gree of malignancy ,invasive ability and a fatal prognosis .In recent years ,with the development of modern technol-ogy in biomedical sciences ,the understanding on GBM has developed gradually from pathological diagnosis to mo -lecular classifications ,which is based on the molecular characteristics of genetic signatures .Based on gene expres-sion and DNA methylation patterns , primary glioblastoma is divided into four subtypes , including the classical , neural,proneural and mesenchymal .These molecular classifications are closely relevant to the biological charac-teristics of glioblastoma .This review briefly introduces the molecular classifications of primary glioblastoma , but mainly focuses on the changes of the major genetic EGFR ,PTEN and PI3K,CDKN2A in the classical subtype of GBM,and discusses the treatment strategies for primary glioblastoma .

Objective To explore the clinical features and surgical management of aged patients with acute cholecystitis,and try to command the opportunity and procedure of laparoseopic cholecystectomy(LC)better.Meth- ods Clinical data of 52 aged cases with acute cholecystits undergone LC were analyzed retrospectively.Results All of the patients(within 48h of the acute attack)were successfully recovered without serious operative complications. Conclusion Aged acute cholecystitis progressed rapidly and its operative difficulty and risk were higher;only if more attention was paid to perioperative managements and operative time and technical skill were mastered,early LC for the patients was safe and feasible.Therefore.it should be recommended in the great majority of cases except the des- perate patients whose general condition was too poor to operate.

OBJECTIVETo establish the "clinical-mimetic" Chinese medicine symptom complex score method for the coronary heart disease Chinese miniature swine model with phlegm-stasis cementation syndrome, in order to observe the effect of formula of removing both phlegm and blood stasis (TYTZ) on the Chinese medicine symptom complex score for the coronary heart disease Chinese miniature swine model with phlegm-stasis cementation syndrome.

METHODTotally 36 Chinese miniature swine were randomly divided to the normal control group, the model group, the Shujiangzhi group, and TYTZ groups with doses of 2.0, 1.0 and 0.5 g x kg(-1), with six in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. After the operation, the groups were administered with drugs for eight weeks. Their main symptoms, accompanied symptoms, tongue and pulse signs of the coronary heart disease Chinese miniature swine with phlengm-stasis cementation syndrome were observed according to the symptom-graded scoring method.

RESULTCompared with the model group, TYTZ in different doses could reduce the scores of main symptoms at the 6th and 10th week. Specifically, TYTZ in low dose could reduce the scores of tongue at the 6th week and the scores of accompanied symptoms, and tongue and pulse signs at the 10th week; And TYTZ in high dose could decrease all symptom scores at the 6th and 10th week (P < 0.05 or P < 0.01).

CONCLUSIONTYTZ can improve the scores of the main symptoms, accompanied symptoms, tongue and pulse signs in coronary heart disease Chinese miniature swine with phlegm-stasis cementation syndrome. It is suggested that the "clinical-mimetic" objective scoring for syndromes of Chinese miniature swine is of great significant to the development of new traditional Chinese medicine drugs.

OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.

METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.

RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).

CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

Objective:To investigate the expression status of Sonic Hedgehog signaling genes and molecules in human hepatocellular carcinomas(HCC),and to explore the relationship between these genes and clinical prognosis.Methods:HCC tissue and adjacent normal tissue from 29 HCC patients were assayed for the expression of hedgehog signaling genes by reverse transcription-polymerase chain reaction chain reaction(RT-PCR) techniques and for the expression of hedgehog signaling molecules by immunohistochemistry.The expressions of Shh,Ptch,Smoh,Gli-1 mRNA were assayed as well as Shh,Ptch proteins in 29 cases of HCC and in 29 liver tissues adjacent to the tumor.Results:Expression of Shh mRNA was detectable in about 51% of HCCs examined.Consistent with this,hedgehog target genes Ptch,Smoh and Gli-1 mRNA were expressed in over 68%,48% and 62% of the tumors,respectively,and the expressions of Shh and Ptch proteins in HCC tumor tissues correlated with those of Shh and Ptch mRNA in tumor tissues(P=0.041 and P=0.035).This suggested that the hedgehog pathway was frequently activated in HCCs.The simultaneous expression of Gli-1 in HCC and liver tissues adjacent to the tumor had significantly relationship with poor prognosis.Conclusion:Hedgehog signaling activation is an important event for development of human HCCs.It also suggests that markers for hedgehog signaling activation may be useful for the determination of prognosis.

Recombinant Fl-V (rFl-V) fusion protein is the main ingredient of the current candidate vaccine against Yersinia pestis infection, which has been under investigation in clinical trial in USA. We investigated the soluble expression conditions of rF1-V in Escherichia coli BL21 (DE3) that we constructed before. After scale-up and optimization of fermentation processes, we got the optimized fermentation process parameters: the culture was induced at the middle exponential phase with 50 µmol/L of IPTG at 25 °C for 5 h. Soluble rFl-V protein was isolated to 99% purity by ammonium sulfate precipitation, ion exchange chromatography, hydrophobic chromatography and gel filter chromatography. The protein recovery was above 20%. Protein identity and primary structure were verified by mass spectrometry and Edman sequencing. Results of purity, quality and western blotting analysis indicated that the target protein is a consistent and properly folded product. Furthermore, the immunogenicity of various antigens formulated with aluminum hydroxide adjuvant was evaluated in mice. Serum antibody titers of 4 groups including 20 µg rFl, rV and rFl-V and 10 µg rFl+10 µg rV, were assayed by ELISA after 2 doses. The antibody titers of anti-Fl with 20 µg rFl-V were obviously higher than titers with other groups; meanwhile there were no significant difference of anti-V antibody titers among them. These findings confirm that rFl-V would be the active pharmaceutical ingredient of the plague subunit vaccine.

Objective To investigate the preliminary clinical outcome following PCL-retaining total knee arthroplasty (TKA) with 0°or 5°posterior tibial slope. Methods From Jan 2008 to Mar 2009, 84 patients (84 knees) with osteoarthritis (OA) underwent primary PCL-retaining TKA operations by the same surgical team. Among them, 27 patients (7 males, 20 females, with the average age of 69.5 years) underwent TKA using a cutting block and intramedullary cutting guide designed to impart a 5° posterior tibial slope (group A); 57 patients (15 males, 42 females, with the average age of 67.4 years) underwent TKA using a cutting block and intramedullary cutting guide designed to impart a 5°posterior tibial slope (group B). The preoperative demographic data and functional data had no statistical differences. The postoperative tibial posterior angle, maximum extension, maximum flexion and Knee Society Score (KSS) were compared between the two groups. Results All patients were followed up 12～24 months with an average of 15.7 months. No paralysis, wound infection, prosthesis dislocation and loosening were found. The postoperative tibial posterior angle was 5.7°±2.1° in group A and 0.9°±0.6°in group B (P＜ 0.05). The postoperative maximum extension was 0.8°±0.3°in group A and 1.2°±0.4°in group B (P ＞0.05). The postoperative maximum flexion was 115.7°±4.8°in group A and 101.1°±5.6°in group B (P＜ 0.05). The postoperative KSS was 87.6±5.9 in group A and 83.3±7.2 in group B (P ＞0.05). Conclusion Increasing tibial posterior slope improved the postoperative maximum flexion, but not the maximum extension and KSS, in PCL-retaining TKA.
