The cell-free plasma DNA (cfpDNA) has been suggested as a useful tumor marker for its quantitative and qualitative tumor-specific alterations that reflect the biological characteristics and the progression and outcomes of tumors.Therefore,it has been used as liquid biopsy to detect cfpDNA in peripheral blood for the diagnosis,monitoring of clinical effects,and prognosis of malignancies

Objective To study whether ORF3 coded by fap1-orf4 gene locus of Streptococcus pa-rasanguis is involved in the regulation of Fap1 glycosylation and maturation and to investigate whether ORF3 influences Streptococcus parasanguis adhesion. Methods A gene replacement strategy was adapted to con-struct orf3 alleic replace mutant of Streptococcus parasanguis. Complementation assay and Western blot were used to test Fap1 expression levels. Whole saliva-coated hydroxyapatite (SHA) adhesion assay was adapted to determine Streptococcus parasanguis adhension. Results (1) Non-polar was found in strain VT1774, the orf3 alleic replace mutant of Streptococcus parasanguis. (2) Western blot showed that mature Fapl (Mr about 220 × 103) disappeared and were substituted with high molecular weight Fapl (Mr about 470 × 103) in strain VT1774, furthermore, complementation assay showed VT1775, the complementation strain of VT1774, re-stored mature Fapl expression. (3) The binding ability reduced significantly in strain VT1774. Conclusion ORF3 coded byfapl-orf4 gone locus was required for Fap1 glycosylation and maturation in Streptococcus pa-rasanguis, orf3 alleic replacment resulted in Fap1 glycosylation and mature disorder and decreasing of adhen-sion ability of Streptococcus parasanguis.

Objective To investigate whether glucosyltransfernse(GTF) and open reading frame 4 (ORF4) coded by fap1-orf4 gene locus of Streptococcus parasanguis was involved in the regulation of Fap1 glycosylation, and mature and to determine whether there was interaction between GTF and ORF4. Methods A gene replacement strategy was adapted to construct gtf and orf4 allele replace mutant of S. Parasanguis. Complementation assay and Western blot were used to test fap1 expression levels. Yeast two-hybrid analysis and GST pull down assays were adapted to determine the interaction between GTF and ORF4. Results (1) Compared with wild S. Parasanguis, mature Fapl (Mr about 220×103) disappeared and were substituted with high molecular weight Fapl (Mr about 360×103) in gtf or orf4 alleie replace mutants of S. Parasan-guis. Complementation assay showed that pVPT-GFP-gtf and pVPT-GFP-orf4 restored mature fap1 expression in gtf or orf4 alleie replace mutants, respectively. (2) With Yeast two-hybrid analysis, the eotransformants, AH109/pAD-Gtf+pBD-orf4 and AHlOg/pAD-orf4+pBD-gtf growed on SD-LTHA selective ngar plate after streaked, reversely, the eotransformants, AH109/pAD+pBD-orf4,AH109/pAD+pBD-gtf、AH109/pBD+ pAD-orf4、AH109/pBD+pAD-gtf did not grow on SD-LTHA selective agar plate, furthermore, the cotrans-formants, AH109/pAD+pBD-orf4 and AH109/pAD-orf4+pBD-gtfshowed blue during X-α-gal assay. (3) GST pull down assay confirmed the direct interaction between GTF and ORF4. Conclusion There is inter-action between GTF and ORF4 coded byfapl-orf4 gene locus of S. Parasangnis and the formation of the GTF and ORF4 complex was required for the glycosylation and mature of Fapl in S. Parasanguis.

Objective To investigate the relationship between arsenic in drinking water and skin lesions in endemic arsenism area in Shanyin County of Shanxi Province,in order to provide epidemiologic data for further arsenism research.Methods One hundred and eighty-nine endemic arsenism patients and 59 controls were randomly selected in 17 endemic amenism countries in Shanyin County of Shanxi Province.The content of arsenic in drinking water which wa8 collected indoom was half-quantitatively screened by a kit made by Chinese Center for Disease Control and Prevention,then quantitatively determined by HPLC-ICP-MS.Patients of endemic arsenism were diagnosed by "The Standard of Diagnosis for Endemic Amenism"(WS/T 211-2001).Results There were 64.9% (87/134)samples above the arsenic level(50μg/L)of drinking water and the median value of arsenic in drinking water was 91.43 μg/L in 134 water samples.The OR(95%CI)value between arsenic in drinking water and hyperkeratosis,hyperpigmentation,depigmentation was 2.46(1.22-4.94),3.34(1.50～7.44)and 2.86(1.50-5.46),respectively.The prevalence of hyperkeratosis,hyperpigmentation and depigmentation increased,as the arsenic in drinking water increased(≤10,≤50,≤200,＞200μg/L),especially in＞200μg/L group(OR=6.15,13.96,11.41,P＜0.05).The arsenic level in drinking water of Ⅲ degree of depigmentation patients(318.300μg/L)was higher(P＜0.05)than that of 0,Ⅰ and Ⅱ degree groups(86.670,131.800,1 10.590μg/L,P＜0.05).Conclusions Shanyin County is a medial arsenic pollution area. Arsenic in drinking water is considered as a risk factor of skin lesion. The degree of skin lesions increased,as the arsenic in drinking water increased.

OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.

METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.

RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).

CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

OBJECTIVETo investigate the effects of simvastatin (SIM)on cardiac hypertrophy and association with calcium channel modulation in rats with myocardial hypertrophy.

METHODSMyocardial hypertrophy was induced by abdominal aortic constriction (AAC) in adult SD rats. Following groups were studied (n=8 each): sham group, AAC group, AAC+ verapamil group (10 mg x kg(-1) x d(-1) per gavage for 4 weeks), AAC +SIM group (10 mg x kg(-1) x d(-1) per gavage for 4 weeks) AAC + SIM + mevalonic acid (50 mg x kg(-1) x d(-1) per gavage for 4 weeks) group. Systolic blood pressure (SBP), echocardiography, heart weight/body weight (HW/BW) and left ventricle weight/body weight (LVW/BW) ratios were measured. The protein and mRNA expressions of L-type calcium channel subunit alpha1 C and T-type calcium channel subunit alpha1 G and alpha1 H were detected by Western blot and RT-PCR respectively.

RESULTSSBP, HW/BW, LVW/BW, IVS and LVPW thickness, left ventricular weights were significantly increased in AAC rats and these effects could be significantly reduced by verapamil and SIM. The protein and mRNA expressions of alpha1 G and alpha1 H were significantly increased in AAC rats which could also be significantly inhibited by SIM or verapamil. The effects of SIM could be blocked by cotreatment with mevalonic acid. Protein and mRNA expressions of L-type calcium channel alpha1 C were similar among groups.

CONCLUSIONSimilar as verapamil, SIM could prevent AAC induced cardiac hypertrophy, possibly via inhibiting T-type calcium channel subunit alpha1 G and alpha1 H re-expression.

Objective To explore the changes in cardiac index and oxygenation index in sepsis piglets after nitric oxide (NO) gas inhalation. Methods A piglet model of sepsis was induced by intravenous infusion of Gram-negative bacterial endotoxin (LPS), then the piglets were randomly divided into two groups. NO group (n=8) was administered with inhaled nitric oxide of 80ppm via volume control (VC) mechanical ventilation for one hour, while the control group (n = 4) received mechanical ventilation with VC and was observed for one hour to assess the stability of the model. The parameters of oxygenation and hemodynamics were measured by PICCO and arterial blood gas analysis every fifteen minutes for one hour. Results Injection of endotoxin induced a stable pig model of sepsis. PH, HCO3-, arterial oxygen pressure (PaO2), mean arterial pressure (MAP) and cardiac index in this model were significantly lower the baseline values (P < 0.01). Arterial oxygen pressure and cardiac index were significantly higher in N0 group than in the control group (P<0.01). Heart rate (HR), central venous pressure (CVP), global end-diastolic volume index (GEDI) and intrathoracic blood volume index (ITBI) did not significantly differ between NO group and the control group. Conclusions Inhalation of nitric oxide gas can significantly improve oxygenation and cardiac function in piglets with sepsis.

Objective To compare complications of ureteroneocystostomy and end-to-end ureteroureterostomy after kidney transplantation. Methods Eighty allograft renal transplantation patients between January 2005 and October 2008 were divided into two groups according to urinary tract reconstruction approach: ureteroneocystostomy group (40 cases) and ureteroureterostomy group (40 cases). Complications including leakage of urine,vesicoureteral reflux,obstruction of ureter and urinary tract infection were recorded.Results In ureteroneocystostomy group and ureteroureterostomy group,the patients were followed up for 13 - 46 (24.5 ± 8.9), 13 - 46 (26.0 ± 7.2) months postoperatively, urinary complications were recorded for 10 eases (25.0%, 10/40) and 4 cases (10.0%, 4/40)(P > 0.05), incidence of leakage of urine were 2.5%(1/40)and 5.0%(2/40) (P > 0.05), vesicoureteral reflux were 10.0% (4/40) and 0 (P ＜ 0.05), obstruction of ureter were 0 and 5.0% (2/40) (P > 0.05), and urinary tract infection were 12.5% (5/40) and 0 (P < 0.05).Conclusions Compared with ureteroneoc ystostomy, ureteroureterostomy can reduce the incidence of vesicoureteral reflux and urinary tract infection,it can be regarded as the first choice for urinary tract reconstruction after kidney transplant recipients.
