Objective:To analyze the expression of the four mismatch repair genes protein (hMLH1,hMSH2,hMSH6 and hPMS2) of patients with colorectal cancer and its clinical significance.Methods:177 cases of patients with colorectal caner in the Third Affiliated Hospital of Guangzhou Medical University from January 2013 to December 2015 were randomly selected.Tested the expression of the hMLH1,hMSH2,hMSH6 and hPMS2 by immunohistochemistry,the relationship between protein expression and clinical parameters was analyzed.Results:Among 177 cases ofcolorectal cancer tissue,the deletion rate ofhMLH1 protein was 6.2％ (11/177),the deletion rate of hMLH2 protein was 4.0％(7/177),the deletion rate of hMSH6 protein was 1.7％(3/177),the deletion rate of hPMS2 protein was 8.0％(14/177),the sum of the four values accounted for 19.8％(35/177) of all cases of colorectal cancer.The loss of expression of the four mismatch repair genes protein were correlated to tumor location (P＜0.05),besides,the loss of expression of the hMLH1 and hPMS2 protein were correlated to degree of tumor differentiation (P＜0.05),he loss of expression of the hMSH6 protein were correlated to depth of tumor invasion(P＜0.05);But the loss was not correlated to age,sexes,lymph node metastasis and distant metastasis(P＞0.05).Conclusion:The expression of loss phenomenon with mismatch repair protein appears in part of colorectal cancer,the loss phenomenon with mis match repair protein were correlated to tumor location and degree of tumor differentiation.Mutations of four genes in hMLH1,hPMS2,hMSH6 and bMSH2,to provide a reference value for the clinical judgment of prognosis and to develop a treatment plan.

Objective To analyse the significance of proto oncogene protein in oral squamous cell carcinoma and oral leukoplakia.Methods 40 patients who were diagnosed with oral leukoplakia (OLK),40 patients who were diagnosed with oral squamous cell carcinoma(OSCC),and at the same time, 40 healthy volunteers as control group were collected.the lesions and normal oral mucosa were taken as samples, left supernatant after grinding, MDM2 protein, p53 protein and Ki-67 protein were detected by ELISA in three groups,and analyse the correlation between three groups.Results Among three groups,MDM2, p53 expression:OSCC group>OLK group>control group (P<0.05).Ki-67 expression level among three groups, OSCC group>OLK group>control group (P<0.05).MDM2, p53, Ki-67 expression had a positive correlation in OSCC group and OLK group (P<0.05), but there was no obvious correlation in control group.Conclusion When oral leukoplakia developes into oral squamous cell carcinoma, MDM2, p53, Ki-67 shows high expression, and there is a positive correlation between MDM2, p53, Ki-67.

Objective To analyze the clinical characteristics and coagulation parameters of the infants with placental abruption . Methods Analysis was made on clinical and laboratory indexes of the hospitalized children of the NICU of Bayi Clinical Medical College of South Medical University ,enrolled from August 2012 to January 2013 ,including 60 infants with placental abruption as observation group and 60 infants without placental abruption as the control group .Results From clinical manifestations and lab date ,significant differences were found in gestational age ,polyembryony ,premature rupture of membrane ,birth weight ,intrauterine growth retardation ,motherhood gestational hypertension ,mother gestational diabetes mellitus ,asphyxia ,APTT ,D-dimer on admis-sion between the observation group and control group (P<0 .05) .Conclusion Placental abruption is the result of placental insuffi-ciency ,which may cause coagulation disorder and thus show the pathological state of high condensation in infants .

Objective To investigate the correlation of bone mineral density (BMD) with plasma Klotho levels and its related factors in type 2 diabetic patients (T2DM) . Methods BMD was measured by Dual-energy X-ray absorptiometry (DEXA) in 159 T2DM patients. The patients were divided into three groups:normal bone mass, reduced bone mass and osteoporosis. The fasting plasma levels of Klotho were detected in these patients using enzyme linked immuno sorbent assay (ELISA), clinical and biochemical parameters also were tested, the difference and related factors were compared and analyzed in each group. Results Plasma Klotho levels were not significantly different among the three groups (4.95±0.48 vs 4.96±0.47 vs 4.91±0.49,P>0.05) . BMD at the first, second, third, fourth and total lumbar spine, femoral neck, trochanter and total body were not associated with plasma Klotho levels in these patients (P>0.05) . Age, diabetic duration, HDL-C and BMI were independent determinants for BMD in T2DM patients. Conclusions BMD might be not associated with plasma Klotho level in T2DM patients. But age,diabetic duration,HDL-C and BMI are associated with reduced BMD and osteoporosis in T2DM patients.

Objective To study the effects of chloroquine on proliferation and cell cycle of hepatocellular carcinoma cell line HepG2 cultured in vitro and provide basis for research on chloroquine in therapy for liver cancer.Methods HepG2 cells were divided into six groups:control group and chloroquine (8.00,16.00,32.00,64.00 and 128.00 mmol?L-1 )groups.The cell viability was determined by MTT,the cell cycle and apoptosis were detected by flow cytometry.Results Compared with control group,the cell viabilities were inhibited significantly 24 h after treated with chloroquine (32.00-128.00 mmol?L-1) or 48-72 h after treated with chloroquine (8.00-128.00 mmol?L-1) ( P

Objective To select the proper enhanced methods of histogram egualization for the medical digital image. Methods By means of the full-frame histogram equalization(FFHE),local-area histogram equalization(LAHE) and adaptive-meighborhood histogram equalization(ANHE),medical digital images were enhanced,and the characteristics of these three methods were compared. Results Through the gray-level histogram equalization,the detail and the edge of medical digital images could be enhanced. Conclusion Toenhance the detail of local issue,it is better to use ANHE method.To enhance the edge of full image,which the full information must been taken into account,it is better to use FFHE method.

Objective To compare imaging quality and radiation dose of different anode filter combination for full-field digital mammography.MethodsThe image of FLUKE NA 18-220 phantom were taken at full-field digital mammography (FFDM),system with Mo/Mo,Mo/Rh,Rh/Rh anode/filter combination by automatic exposure control,record the exposure factors and doses.The images on monitor with the best window width and window level were read by 4 independent radiologists,the images of specks groups,nylon fibers and masses was assessed by the 4 experienced readers at the criterion of American College of Radiology 1999 mammography quality control manual.Statistical analysis was performed using analysis of variance.ResultsThe nylon fibers scores of Mo/Mo,Mo/Rh and Rh/Rh were 5.50 ± 2.12,4.50 ± 1.85 and 4.38 ± 1.38 ; the specks groups scores of Mo/Mo,Mo/Rh and Rh/Rh were 5.38 ± 1.98,4.25 ± 1.56 and 4.38 ± 1.38;the masses scores of Mo/Mo,Mo/Rh and Rh/Rh were 5.38 ± 1.98,4.38 ±1.68 and 4.25 ± 1.56,the detection of specks groups,nylon fibers was not statistically significant ( F =4.56 and 4.32,P ＞ 0.05 ),but the detection of masses was statistically significant ( F =36.65,P ＜ 0.05).The radiation doses were different,the entrance surface dose (ESD) and average glandular dose (AGD) of Rh/Rh were (5.11 ± 1.89) and ( 1.08 ± 0.13 ) mGy,the ESD and AGD of Mo/Mo were (6.66 ± 2.33 )and ( 1.29 ± 0.38 ) mGy,the ESD and AGD of Mo/Rh anode/filter combination were (5.67 ± 2.02) and ( 1.29 ± 0.38) mGy.ConclusionsThe radiation dose of Rh/Rh and Mo/Rh anode/filter combination of FFDM were lower,and the imaging was clear,so Rh/Rh and Mo/Rh anode/filter combination of FFDM prefer to mostly patients,especially when the thinkness is large,Rh/Rh anode/filter combination is preferred,because the kV values was higher,the penetration of X-ray was stronger.The Mo/Mo anode/filter combination was used when the needs of high-resolution,because the detection of masses of it was better.
