Purpose Discover new prostate cancer-related single nucleotide variants.Methods Tissue wax blocks from 21 prostate cancer patients who underwent radical surgery and had relatively complete clinical data were collected for somatic mutation detection to analyze new mutated genes associated with prostate cancer.The levels of cor-responding proteins in the urine of prostate cancer patients were tested according to the results of the selected genes.Results All 21 prostate cancer patients showed obvious somatic mutations,and the mutation types were dominated by C＞T and G＞A.The number of somatic mutations was 521,of which 27 genes had high mutation proportions(≥2 ca-ses),including ZSWIM6(5/21),FOXA1(4/21),SPTA1(2/21),FAM47C(2/21),FLG2(2/21),PRSS3(2/21),TP53(2/21),FLG(2/21),UBR4(2/21),and the mutations occurring in ZSWIM6 were all deletion muta-tions,and the mutations occurring in FOXA1 were missense mutations,deletion mutations,and deletion insertion mu-tations.The urinary levels of UPF1,SPTA1,and IDH1 proteins of the 10 prostate cancer patients were significantly different than those of the healthy controls.Correlation analysis showed that FOXA1 was positively correlated with UBR4(r=0.669,P=0.001),SPTA1 was positively correlated with FLG2(r=1.000,P＜0.001),FAM47C was positively correlated with PRSS3(r=1.000,P＜0.001),and there was a significant positive correlation between TP53 and FLG(r=1.000,P＜0.001).ZSWIM6 and FOXA1 were not correlated with biochemical recurrence.SP-TA1 mutation affected progression-free survival(PFS)[(66.0±0)months vs(30.0±7.8)months,P=0.008].FAM47C was positively correlated with PFS[(66.0±0)months vs(19.0±0)months,P＜0.001].ZNF676 was correlated with PFS[(66.0±0)months vs(26.0±5.0)months,P=0.008].FLG2 was correlated with PFS[(66.0±0)months vs(30.0±7.8)months,P=0.008].PRSS3 was correlated with PFS[(66.0±0)months vs(19.0±0)months,P＜0.001].Conclusion All 21 prostate cancer patients harbored somatic mutations,including ZSWIM6(5/21)and FOXA1(4/21)mutations.SPTA1,FAM47C,ZNF676,FLG2,and PRSS3 may be associated with prognosis.

The British and French language analogy method in bilingual teaching was applied to the clinical students who were learning medical French in Kunming Medical University. Based on the students' good English foundation , a series of problems were solved properly such as contradictions between the professional course and foreign language classes , unmatched textbooks and teaching con-tents, the teachers' quality by lexical analogy and textual analogy and the rational allocation of the British and French language analogy teaching content. The teaching contents and methods were also properly worked out and good results were got.

Objective To investigate the normal ranges of RET-He and reticulocyte grouping parameters of healthy adults in Wenzhou. Methods A total of 1 000 samples from healthy adults were collected in Wenzhou from August 2008 to February 2010. There were 506 males and 494 females. The individuals were stratified based on age into three groups:20 to 40-year-old group (n = 341 ), ＞40 to 60-year-old group (n =316), and ＞60-year-old group (n =343). All blood samples were drawn in EDTA-K2 anticoagulated blood. Peripheral RET-He and reticulocyte grouping parameters ( IRF, LFR, MFR, HFR)were determined by Sysmex XE-2100 automated hematology analyzer. The instrument was calibrated and validated before testing All specimens were analyzed within 2 hours. RET-He, RET absolute value and RET percentage were normal distribution, the normal range was established by using ((x)-1.96s,(x)+ 1.96 s)method. IRF, LFR, MFR and HFR data were skewed distribution,the normal range was established by using (P2.5 ,P97.5 )percentile method. Results The mean and normal range of RET-He were (33.91 ± 1.77) pg and (30.44 - 37.38) pg in male, (33.97 ± 1.85) pg and (30.34 - 37.60) pg in female,respectively. There was no significant difference between the two groups ( t =-0.533, P＞0.05 ). The mean and normal range of RET absolute value were (0.051±0.023) × 1012/L and (0.006 -0.096)×1012/L in male,which were (0. 037 ±0. 026) × 1012/L and (0 -0. 088) × 1012/L in female, there was significant difference between the two groups ( t = 8. 409, P ＜ 0. 05 ) . The mean and normal range of RET percentage in male were(1.041 ±0.459)% and (0. 141 -1.941)% , and in female were (0.869±0.603)% and (0-2. 051 )%, which showed significant difference (t =5.074,P ＜0. 05). The normal ranges of LFR,MFR,HFR,IRF in male were 0. 951 (0.866 -0.988) ,0.046(0.010 -0.114) ,0. 003(0 -0.023) ,0. 050(0.012-0.134), and in female were 0.096(0.880 -0.991) ,0.039(0.008 -0.113) ,0.002(0-0.016) ,0.040(0.009-0.121), respectively. There were significant differences between the two groups (Z values were -5.044, -4.793, -3.559, -5.075, respectively,all P＜0.05). The means of RET-He in 20 to 40-year-old group, ＞40 to 60-year-old group, ＞ 60-year-old group and all age group were (33.38±1.49),(34.36 ±1.46), (34.12±2.21) and (33.94 +1.81) pg, respectively. The normal ranges were(30.46-36.30), (31.50 -37.22), (29.79 - 38.45) and (30.39 - 37.49) pg, which showed statistical difference( F =28. 072,P ＜0. 05). In addition, the normal range of RET-He in 20 to 40-year-old group was lower than that of ＞ 40 to 60-year-old group and ＞ 60-year-old group ( q values were 9. 970, 7. 791,respectively, P＜0. 05). The normal ranges of LFR, MFR, HFR, IRF in ＞ 60-year-old group were 0.961(0. 878 -0. 992) ,0. 037(0. 007 -0. 105 ) ,0. 002(0 -0. 020) and 0. 039(0. 008 -0. 117) ,while they were 0.953(0. 867 -0.990), 0.045(0.009 -0. 116) ,0.003(0 -0.019) ,0. 050(0. 010 -0. 133) in 20 to 40 -year-old group , and 0. 951 (0.855 -0.989) ,0.047 (0.010 - 0.133 ) ,0.003 ( 0-0.020), 0.049 (0.011-0.149)in ＞40 to 60-year-old group, which showed statistical difference (Z values were -3. 949, -4.236,-4. 373, -4. 973, - 2. 747, - 3. 275, - 3.901, - 4. 185, respectively, all P ＜ 0. 05). There was nodifference between male and female for RET-He, the same normal ranges could be used, but there was significant difference between different age groups. LFR, MFR, HFR and IRF were statistically different between different age groups and different sex groups. The normal ranges should be established by gender and age. Conclusion The normal ranges of RET-He and reticulocyte grouping parameters about healthy adults in Wenzhou are established, which plays an important role in clinical value of RET parameters.

Objective To study the relation of the porin at the out membrane with resistance to cefoxitin in Enterobacter cloaceae. Methods The extended spectrum beta lactamase(ESBLs) was detected by phenotypic confirmatory test according to NCCLS M100 S9;the beta lactamase and out membrane protein(OMP) was extracted by ultrasonication,the beta lactamase was detected by ultraviolet spectrophotometer,the composition of OMP was analyze by SDS PAGE. Results The 6 strains in 9 strains of Enterobacter cloaceae with resistance to cefoxitin lost 18 kda protein band and did not product hydrolase to cefoxitin and 5 strains was ESBLs positive. 2 strains producing hydrolase to cefoxitin did not lose the 18 kda protein. One strain with resistance to cefoxitin was producing ESBLs but did not defect the 18kda protein band and product hydrolase to cefoxitin. Conclusion The defect of the 18 kda protein band is nearly relation with resistance to cefoxitine in Enterobacter cloaceae.

Methods A total of 1 440 medical college students were tested by self-rating depression scale (SDS), automatic thoughts questionnaire (ATQ) and Eysenck personality questionnaire (EPQ). Results ①27.5% medical college students had different degree depressive mood. ② Compared with the non-depression group students, the depression group had higher scores in ATQ, EPQ-N(neurosism) and EPQ-P(psychoticism), lower scores in EPQ-E(extroversion), EPQ-L(lie) (P
