AIM: To detect the protein expression of protein gene product (PGP9.5) in cervical carcinoma samples, and to explore its relationship with clinicopathological features and prognosis of cervical carcinoma patients.The potential value of PGP9.5-siRNA in the treatment of cervical cancer was preliminarily investigated in vitro.METHODS:The clinical data of cervical cancer patients ( n=180 ) who received surgical treatment in Department of Gynecology of Tianjin Fifth Central Hospital and Tianjin Central Hospital of Gynecology and Obstetrics from January 2008 to June 2015 were retrospectively analyzed.Immunohistochemical staining for PGP9.5 in all pathological specimens from cervical cancer biopsy was performed.The patients were divided into high expression of PGP9.5 group and low expression of PGP9.5 group.The relationship between PGP9.5 expression and clinicopathological parameters, such as age, HPV infection, path-ological grade, tumor diameter, lymph node metastasis, depth of invasion and clinical stage, were analyzed.The overall survival was analyzed by Kaplan-Meier method and the log-rank test.The PGP9.5-siRNA, NC-siRNA, PGP9.5 eukaryotic expression plasmid and empty vector were transfected into the SiHa cells, and the effects of PGP9.5 expression on the abili-
ties of colony formation and cell invasion were determined by Western blot, colony formation assay and Transwell experi-ment.RESULTS:The relationships between the expression level of PGP9.5 and patients’ pathological characteristics in-cluding grade, tumor size, lymph node metastasis, depth of invasion, vascular involvement and clinical stage were statisti-cally significant ( P<0.05) .The overall survival rates of 3 and 5 years in PGP9.5 high expression group were significantly lower than those in PGP9.5 low expression group ( P<0.05 ) .Compared with control group, the protein expression of PGP9.5, the number of colony formation and the number of invasive cells in si-PGP9.5 group were significantly decreased. The protein expression of PGP9.5, the number of colony formation and the number of invasive cells in PGP9.5 group were significantly increased.CONCLUSION:Over-expression of PGP9.5 protein indicates poor prognosis of cervical cancer, which may be a good predictor for the prognosis of cervical cancer patients.Inhibition of PGP9.5 expression may be an ef-fective way of gene therapy for cervical cancer.

Objective To investigate the effect of methylprednisolone on the expression of glial fibrillary acidic protein (GFAP) and proliferating cell nuclear antigen (PCNA) in M?ller cells of rats' retinae injured by laser. Methods Forty SD rats were randomly divided into two groups and inflicted with laser photocoagulation.The rats in treatment group were given methylprednisolone by intraperitoneal injection with a dose of 30 mg/kg for 3 days.At the 3rd,7th,14th,and 28th day after photocoagulation respectively, the eyes were enucleated,fixed and cut into sections.Immunohistochemical examination was used to detect the expression of PCNA and GFAP. Results After photocoagulation the M?ller cells expressed PCNA both in the treatment and control group,and the expression of PCNA decreased sharply after 3 days. The expression of PCNA in treatment group was less than that in control group. After photocoagulation the M?ller cells also expressed GFAP and the expression of GFAP lasted for at least 28 days ,and the expression of GFAP expression in the treatment group was less than that in the control group. Conclusion Methylprednisolone can reduce the expression of GFAP and PCNA in M?ller cells of rats' retinae injured by laser.

Objective To assess the prevalence of c-Kit and FLT3 gene mutations in core binding factor related acute myeloid leukemia (CBF-AML) and analyze the karyotype characteristics of the CBF-AML patients. Methods Mutations of c-Kit, FLT3-ITD and FLT3-TKD were detected by genomic DNA PCR and sequencing, and the karyotype changes were analyzed in 48 newly diagnosed CBF-AML patients. Results c-Kit aberrations were detected in 13(27.1 %) out of 48 patients, including 5 cases with exon 8 mutation and 8 cases with exon 17 mutation. c-Kit was more prominent in t(8;21) AML patients than in inv(16) AML patients [(33.3 %(9/27) vs 19.0 %(4/21), P<0.05]. Only 1 case (2.1 %) had FLT3-ITD mutation (FLT3-ITD+) and 3 cases (6.3 %) had FLT3-TKD mutation (FLT3-TKD +). Prevalence of RUNX1-RUNX1T1 with additional chromosome abnormality was as high as 25.9 %(7/27), in which sex chromosome elimination was the most common one, while prevalence of CBFβ-MYH11 with additional chromosome abnormality was low. Conclusion c-Kit gene mutations and RUNX1-RUNX1T1 additional chromosome abnormalities are common in patients with CBF-AML and would be helpful for individualized treatment studies.
