Objective: To investigate the relation between proliferation, apoptosis and Bcl-2 in human tongue squamous cell carcinoma(TSCC). Methods: Apoptosis, prolifexation and Bcl-2 protein expression were examined in 7 cases of normal tongue mucosa, 20(10 of Han and 10 of Uygur people) of tongue squamous cell papilloma (TSCP) and 42 of TSCC (30 of well-differentiated and 12 of middle-differentiated ) with immunohistochemical and in situ cell death detection technique. Results: The apoptosis index (TI) and the proliferation index (PI) showed no significant difference between Han and Uygur people or between male and femae, TI and PI in human TSCP were heigher than those in normal tongue mucosa, The proliferation was enhanced and apoptosis was inhibited according to dysplasia degree(P

AIM: To investigate whether Janus kinase/signal transducer and activator of transcription ( JAK/STAT) signaling pathway mediates high glucose-induced damage in human umbilical vein endothelial cells ( HUVECs ) . METHODS:The cell viability was examined by CCK-8 assay.The expression levels of JAK2, STAT3, caspase-9 and en-dothelial nitric oxide synthase ( eNOS) were detected by Western blot .The intracellular levels of reactive oxygen species ( ROS) were tested by DCFH-DA staining followed by photofluorography .Mitochondrial membrane potential ( MMP) was measured by rhodamine 123 staining followed by photofluorography .RESULTS:Treatment of HUVECs with high glucose (40 mmol/L glucose) for 6~12 h enhanced the protein level of phosphorylated JAK 2, peaking at 9 h.Treatment of the cells with high glucose for 6~12 h also increased the protein level of p-STAT3 with the peak value at 12 h.Pretreatment with the inhibitor of JAK/STAT pathway AG490 for 1 h before exposure of the HUVECs to high glucose significantly inhibi-ted the high glucose -induced injury , as evidenced by an increase in the cell viability , decreases in the expression of caspase-9 and the intracellular ROS production , and increases in MMP and the expression of eNOS .CONCLUSION:JAK/STAT signaling pathway is involved in the high glucose-induced damage in HUVECs .

OBJECTIVETo explore the relationship between angiotensin converting enzyme (ACE) gene single nucleotide polymorphisms (SNP) and premature coronary heart disease (PCHD) patients with blood stasis syndrome (BSS).

METHODSrs4343, rs4293, and rs4267385 were selected at SNP from ACE gene. Allele and genotype were detected. Frequencies of allele and genotype were compared by using time-of-flight mass spectrometry technique (TOF-MS).

RESULTSCompared with the healthy control group, genotype of rs4293 and rs4267385 in ACE gene were similar, but there was statistical difference in polymorphisms and allele frequencies of rs4343 in the I and II group (P < 0.05, P < 0.01). The frequency of G allele was higher in the 3 groups than in the healthy control group (P < 0.05, P < 0.01). The relative risk analysis showed that the risk for PCHD occurrence in G allele carriers at rs4343 (GG +AG) was 3. 6 times the risk in non-G allele carriers (95% CI: 1.224-10.585, P = 0.02). There was also statistical difference in sex, age, TC, and TG after adjusted Logistic regression analysis (OR = 3.994, 95% CI: 1.230-12.974, P = 0.021).

CONCLUSIONThe polymorphism at rs4343 (G2350A) might be one of risk factors for PCHD occurrence, but not a predisposing factor for PCHD patients of BSS.

The essential medium of B115 composed of 1% tryptone, 0.25% yeast extract and 0.5% sodium chloride was determined by using an orthogonal design. The orthogonal design was also employed in testing the optimum additions. It was composed of 0.1%(NH_(4))_(2)SO_(4),1.4%K_(2)HPO_(4), 0.6% KH_(2)PO_(4) and 0.1% (Na_(3)C_(6)H_(5)O_(7)). The yield of B115 cultured in optimum medium was compared with the one in essential medium. Statistic analysis showed that the growth of B115 was most significantly improved by adding K~(+)、NH~+_(4) and (Na_(3)C_(6)H_(5)O_(7)) to essential medium. The antibacterial effect of Bacillus subtilis strain B115 on pathogenic Aeromonas was studied. The results showed different antibacterial effects of B115 on different aeromonads. There were obvious antibacterial effects on BSK-10 and CL990920, while no effect on the growth of TL970424.

Objective To investigate the features of chronic prostatitis during puberty(CPP)and the effects of pelvic floor biofeedback therapy.Methods Totally,25 CPP children (mean age,16 years) and 15 children (mean age,16 years) with normal lower urinary tract as controls were included.In CPP group,NIH-CPSI scores were evaluated,expressed prostatic secretions (EPS) were examined,and bacterial culture was done;and CPP patients were categorized based on the definitions of NIH types.In both groups, urodynamic examination was performed,including evaluation of uroflow curve,maximum flow rate (Q_(max)), post-voiding residual urine (PVR),detrusor-sphincter dyssynergia (DSD),maximum detrusor pressure (P_(det,max))and maximum urethral closure pressure (MUCP).CPP patients underwent biofeedback therapy, and 10 weeks later the effects were assessed.Results In CPP group,NIH typing showedⅡ,ⅢA andⅢB in 1,3 and 21 cases,respectively.Before treatment in CPP and control groups,the incidence of staccato voiding (20 cases vs 1 case),DSD (22 cases vs 1 case),Q_(max)(10.7?3.7 vs 15.0?4.3ml/s),PVR (7.7?4.1vs 3.2?2.6ml),P_(det,max)(115.1?33.6vs 76.8?16.6cm H_2O)and MUCP(176.5?45.7 vs 86.2?28.5cm H_2O)all showed significant differences between the 2 groups(P＜0.05).In CPP group,the differences in pain(4.6?2.2 vs 2.1?1.6),urination (7.9?2.0vs 2.2?1.7),life impact (9.4?2.2vs 2.6?2.1)and total scores(22.0?5.2vs 7.0?4.2) of NIH-CPSI and Q_(max)(10.7?3.7 vs 14.9?5.6) between pre-and post-biofeedback were significant (P＜0.05).Conclusions The main type of CPP is categoryⅢB.The primary symptom is voiding disorder,which leads to greater psychological stress in patients.Children with CPP have pelvic floor dysfunctions and multiple abnormal urodynamic param- eters.The short-term effect of biofeedback strategies for CPP is satisfactory.
