Objective To investigate the role of IFN-γ and FOXP3 expression in subpopulation distribution and functions of tumor-infiltrating lymphocytes (TILs) in the microenvironment of renal cell cancer.Methods 30 renal cell cancer tissue samples were freshly collected from the laparoscopic radical nephrectomy in the first hospital of Jiaxing.After frozen sectioning,immunofluorescent staining was conducted to detect the infiltrating CD4 positive and CDs positive cells,and the expression of FOXP3 and IFN-γ as well.In addition,TILs were isolated from the tumor tissues by density-gradient centrifugation.TILs from tumor center or tumor invasive edge were purified independently and measured for the mRNA levels of FOXP3 and IFN-γ by qRT (quantitative reverse transcription)-PCR.Results Tumor-infiltrating CD4+ and CD8+ T cells were concentrated in the invasive edge of renal cell cancer tissues.The expression of FOXP3 was found to be inversely related to that of IFN-γ from the immunofluorescent staining.The relative FOXP3 mRNA levels for the TILs from tumor center and invasive edge were 64.6 ± 9.4 and 36.2 ± 1.8,respectively,with significant difference(P ＜0.05).The relative IFN-γ mRNA levels were 631.8 ± 151.4 and 1 726.0 ± 344.1 (P ＜ 0.05).The trend of relative expression of FOXP3 was reversed in terms of IFN-γ.Conclusions The study on the renal cell cancer tissue samples suggested that the tumor-specific cytotoxic immune cells relatively concentrated in the tumor invasive edge.

OBJECTIVE: To determine the chlorpyrifos in human blood by liquid chromatography-tandem mass spectrometry and to validate its application in poisoning cases. METHODS: The samples were extracted by a simple one-step protein precipitation procedure. Chromatography was performed on a Capcell Pack C18 MGII column (250 mm x 2.0 mm, 5 μm) using an isocratic elution of solvent A (0.1% formic acid-water with 2 mmol/L ammonium acetate) and solvent B (methanol with 2 mmol/L ammonium acetate) at 5:95 V:V). RESULTS: The linear ranged from 5 to 500 ng/mL (r = 0.998 7). The limit of detection (LOD) and the lower limit of quantification (LLOQ) were 2 ng/mL and 4 ng/mL, respectively. For this method, the precision and accuracy of intra-day and inter-day were < 10% and 97.44%-101.10%, respectively. The results in stability test of long-term frozen were satisfied. The matrix effect, recovery and process efficiency were 64.97%-86.81%, 76.70%-85.52%, and 55.57%-66.58%, respectively. CONCLUSION This method can provide a rapid approach to chlorpyrifos extraction and determination in toxicological analysis of forensic and clinical treatment.

OBJECTIVE: To explore the change rules of peak area ratio of STR loci to Amelogenin (AMEL) locus (STR/AMEL), a sex-determining gene in DNA degradation, and to evaluate the application of STR/AMEL value in the estimation of DNA degradation degree. METHODS: DNA was extracted from iliopsoas, and the variations of STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) were analyzed after the artificial degradation was made by DNase I, and the changes of these three ratios of the iliopsoas naturally degraded in an outdoor environment were also analyzed. The regression curves were analyzed using the periods of DNA degradation and outside the body as the independent variable (x) and the STR/AMEL value as the dependent variable (y) and three curve equations under two conditions were established. RESULTS: Both under the conditions of artificial and natural degradation, STR/AMEL value had a negative relationship with the degradation time. The relationship between STR/AMEL and degradation time can be well simulated by the cubic function. R2 was over 0.99 under controlled degradation condition and over 0.86 under natural degradation condition. CONCLUSION The STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) is negatively related with the DNA degradation degree, which follows mathematical regression models strictly, and it might be applied to evaluate the DNA degradation degree.

OBJECTIVETo investigate the clinical application of the ureteral dilation catheter combined with the balloon catheter under the ureteroscope in the treatment of urethral stricture in men.

METHODSUnder the ureteroscope, 45 male patients with urethral stricture received placement of a zebra guide wire through the strictured urethra into the bladder and then a ureteral dilation catheter along the guide wire, followed by dilation of the urethra from F8 initially to F14 and F16. Again, the ureteroscope was used to determine the length of the strictured urethra, its distance to the external urethral orifice, and whether it was normally located. An F24 balloon catheter and then a metal urethral calibrator was used for the dilation of the strictured urethra. After removal of the F18-F22 urethral catheter at 8 weeks, the urinary flow rate was measured immediately and again at 3 months.

RESULTSAll the operations were successfully performed without serious complications. The maximum urinary flow rate was (13.3-29.9) ml/s (mean [17.7 ± 3.2] ml/s) at the removal of the catheter and (15.2-30.8) ml/s (mean [19.8 ± 3.9] ml/s) at 3 months after it. Smooth urination was found in all the patients during the 6-24 months follow-up.

CONCLUSIONThe application of the ureteral dilation catheter combined with, the balloon catheter under the ureteroscope is a good option for the treatment of male urethral stricture for its advantages of uncomplicatedness, safety, effectiveness, few complications, less pain, high success rate, and repeatable operation.

This paper describes a new technique in the repair of the hand defect with digital extensor tendon injury. The anterolateral thigh flap with the thick femoral fascia has been used in the reconstruction of the composite defect of the dorsal hand, especially the defect of tendon. This technique requires short period of treatment and hence causes less damage to the donor site but shows a better recovery of the hand function. A favorable curative effect has been obtained in this patient.

Objective To evaluate whether Ly294002,suppressing phosphatidylinositol 3 kinase (PI3K)/AKT survival signaling pathway,can change the sensitivity of breast cancer cells to radiotherapy. Methods Breast cancer cultured MCF7 cells treated with:radiation alone;Ly294002;or the combination of radiation and Ly294002.The inhibition of PI3K/AKT by Ly294002 was confirmed by Western blot.Clo- nogenic assay was used quantitatively to measure the mitotic cell death,and caspase-3 assay was used to e- valuate apoptosis.Results 1.Ly29400 could partially inhibit phosphorylated AKT but not radiation,the combination of both could enhance the inhibition of phosphorylated AKT,2.Timing of exposing cells to Ly294002 had some impact on clonogenic survival by radiation,one hour pre-radiation and 10 days post-ra- diation exposing to Ly294002 could maximally sensitize the cells to irradiation,3.Ly29400 combined with radiation could synergistically enhance mitotic death and apoptosis of MCF7 cells,with SER of SF_4 and D_0, being equal to 1.25 and 1.42.Conclusions PI3K/AKT pathway may be a potential target for enhancing the response of breast cancer cells to radiotherapy.

ObjectiveTo evaluate the trauma care effect and the value of trauma and injury severity score (TRISS) in prediction of the mortality by using TRISS to calculate the survival probability of trauma patients in five hospitals from Zhejiang province in 2009.MethodsA retrospective study was done on trauma patients (study group) firstly admitted to Emergency Department of five hospitals from Zhejiang province in 2009.The relevant information was collected,including demographic data,trauma types and injury causes.The TRISS score was obtained through calculating injury severity score (ISS) and revised trauma score (RTS) on admission into emergency department.With the major trauma outcome study (MTOS) as control group,M value,standardized Ws value and 95％ confidence interval (CI) were calculated to compare actual survival rate and anticipation survival rate.ResultsA total of 2 193 patients at mean age of 44.39 years were enrolled in the study,including 1 661 male patients (75.74％).Traffic accident injury was the most common,followed by fall injury.The mortality rate according to TRISS was 13.22％,but the actual mortality rate was 9.75％.For all the patients,M =0.80 indicated that the injury severity of the study group was significantly different from that of the control group.At the same time,Ws =2.15,95％ CI for Ws:1.54-2.77 showed that the actual survival rate of the study group was significantly higher than that of the control group.Besides,the survival rate of trauma patients in the affiliated hospitals and three hospitals at class A grade was significantly higher fian that of the control group,but there was no significant difference between three hospitals at class B grade and control group. ConclusionsTRISS overestimates the mortality of the study group,which is probably associated with the rapid development of traumatology and the old coefficients of TRISS.Setting up local trauma database and renewing coefficients of TRISS may improve the ability of TRISS in predicting mortality of the trauma patients.
