In this paper,the candida carrier rate of 1996 healthy infants and juveniles of the Han,Dai and Zang nationalities was reported.The specimens were taken from the tongue,cheek mucosa,stool,urine,finger web and vagina.The carrier rate of C.albicans in the mouth was significantly higher than that in the other regions. C.albicans at the tongue of the Han,Dai and Zang people was 4.5%,5.3%, 1.07% respectively.Therefore,C.albicans' residence in the mouth was probably an important source of the internal infection of candidiasis.Of the 1996 healthy individuals none had C.albicans isolated from the urine.The carrier rate of C. albicans isolated from the vagina was only 0.15% in the Han and zero in the Dai and Zang.The carrier rate of candida was least in the newborn.Our data also suggested that the carrier rate of candida at the tongue was much higher than that at the cheek mucosa.Regard must be paid when isolating fungi from the mouth.

Objective To investigate the significance of orthotopic liver transplantation in the management of primary hepatocellular carcinoma (PHC) ; To evaluate the survival and prognostic factors of liver transplantation for PHC.Method The clinical data from 194 consecutive PHC patients who underwent OLT were retrospectively analyzed.Result The 1-,3-and 5-year cumulative survival rate of the 194 patients was 92.78％,78.07％ and 76.80％ respectively.There were 37 cases of recurrence or metastasis of the tumor with the incidence rate being 19.1％ (37/194).The tumor TNM stage (P=0.026 667),tumor diameter (P =0.0045),tumor number (P =0.0318),vascular invasion (P =0.006 059),and AFP level before transplantation (P =0.003 426) were significantly related with tumor recurrence.Multivariate analysis revealed that tumor diameter (P =0.0081,OR =0.789,95％ CI:2.1233-6.124),vascular invasion (P＜0.001,OR =5.928,95 ％ CI:1.173-86.789),and AFP level before transplantation (P =0.019,OR =2.601,95％ CI:2.196-5.658) were independent risk factors for tumor recurrence.There was statistically significant difference in survival rate and tumor-free survival rate between Milan criteria group and beyond-UCSF criteria group (P＜0.01),and between UCSF criteria group and beyond-UCSF criteria group (P＜0.01).There was no significant difference in survival rate and tumor-free survival rate between Milan criteria group and UCSF criteria group (P ＞0.05).Conclusion Liver transplantation is an effective treatment for PHC.The tumor diameter ＞8 cm,vascular invasion and AFP level significantly affect the survival of PHC patients.

Objective To investigate the expressions and clinicopathological significance of 3q27-3q29-related p63 protein in diffuse large B-cell lymphoma (DLBCL). Methods An immunohistochemical Envision~(TM) method was used to detect the expressions of p53 and 3q27-3q29-related p63 protein in 102 cases of DLBCL and 15 cases of reactive hyperplasia of lymph node (RHL). Results The tumor cell expressions of p53(62 %) and p63(56 %) in DLBCL were significantly higher than that in RHL (0 and 13 % P < 0.05). The expressions of p53 and p63 were significantly different (1) between stage Ⅰ + Ⅱ (the positive rate 48.3 % and 41.4 %, respectively) and stage Ⅲ+Ⅳ(the positive rate 79.5 % and 75 %, respectively; P <0.05), (2) between GCB type (the positive rate 28 % and 28 %, respectively) and non-GCB type(the positive rate 72.7 % and 64.9 %, respectively; P <0.05). The expressions of p53 and p63 had no relationship to gender, age, B symptoms and locations. The expression of p53 was positively correlated with that of p63 in DLBCL (P <0.05, Cp=0.629). p53 and p63 protein expression in negative group the 5-year overall survival rate is higher than that in positive group (38 % and 6 %, 51% and 4 %, respectively), the difference was statistically significant (P <0.05). Conclusion It was likely that p63, as the oncogene, participated in the occurrence and development of DLBCL together with p53. Also, p63 and p53 might play a synergistic role in the occurrence DLBCL. Combined detection of 3q27-3q29-related 1963 protein and p53 protein in DLBCL, might be one of the indicators to the prognosis of DLBCL.

OBJECTIVETo study the role of integrin-linked kinase (ILK) on the proliferation and differentiation of human fibroblast in hypertrophic scar and its effect on the scar formation.

METHODSThe human scar fibroblasts were isolated and cultured in vitro. The cells were divided into 4 groups. (1) control group: only contains DMEM; (2) jetPRIME group: DMEM with 200 microl jetPRIME buffer and 4 microl jetPRIME; (3) ILK siRNA group: DMEM and ILK siRNA; (4) ILK cDNA group: DMEM and ILK cDNA. The cell proliferation was detected by XTT assay and the mRNA and protein expressions of ILK and alpha-SMA were detected by Real-time qPCR and Western blot.

RESULTS(1) XTT results showed that the cellular proliferation level after 48 h in four groups were 0.820 +/- 0.065, 0.873 +/- 0.041, 0.554 +/- 0.013 and 1.296 +/- 0.094, respectively. The cellular proliferation curve showed that the cellular proliferation level was very flat in ILK siRNA group while the cellular proliferation level gradually increased from 12 h. 48 h after transfection, the cellular proliferation level in ILK siRNA group was significant lower than those in other groups (P value were 0.021, 0.034, 0), while the cellular proliferation level in ILK cDNA group was the highest among all 4 groups (P value were 0.017, 0.009, 0). (2) The Real-time qPCR showed that the expressions of ILK mRNA and alpha-SMA mRNA were 0.693 +/- 0.412 and 0.422 +/- 0.037 in control group, were 0.621 +/- 0.183 and 0.388 +/- 0.005 in jetPRIME group, were 0.052 +/- 0.019 and 0.073 +/- 0.023 in ILK siRNA group, were 240.193 +/- 35.170 and 138.056 +/- 24.060 in ILK cDNA group. The expressions of ILK mRNA and alpha-SMA mRNA in ILK siRNA group were significantly lower than those in other three groups (P < 0.05). And the expressions of ILK mRNA and alpha-SMA mRNA in ILK cDNA group were significantly higher than those in other three groups (P < 0.05). (3) The Western blot also showed that the expression of ILK and alpha-SMA proteins were decreased in ILK siRNA group and increased in ILK cDNA group.

CONCLUSIONILK may promote the proliferation and differentiation of human scar fibroblast. It may play an important role in scar formation and contracture.
