Objective To investigate the expression and significance of Matriptase and HAI-1 protein in prostate cancer (CaP). Methods Specimens of 46 prostate cancers,20 benign prostate hyperplasias (BPH),10 high-grade intraepithelial neoplasias (PIN),and 10 normal prostates (NP) were used. Expressions of Matriptase and HAI-1 proteins in specimens were detected by SP of immunohistochemistry. The results were analyzed in relation to the clinicopathological data. Results The protein levels of Matriptase in CaP tissues were significantly higher than PIN tissues(Z=-2.150,P=0.032),and the expression of matriptase in CaP and PIN was higher than that in BPH and NP (Z=-3.270,P=0.001;Z=-2.817,P=0.005). No statistically significant difference was observed between BPH and NP group (Z=-0.895,P=0.325). A progressive increase in the protein levels of Matriptase was observed with increasing tumor grade (rs=0.583,P<0.01) and clinical stages(rs=0.611,P<0.01)in CaP specimens. The protein levels of HAI-1 in BPH and NP tissues were significantly higher than CaP and PIN tissues(Z=-3.277,-3.315,P<0.01),the levels of HAI-1 in PIN were higher than CaP (Z=-2.310,P=0.020). No statistically significant difference was found between BPH and NP (Z=-0.872,P=0.330). A progressive decrease in the protein levels of HAI-1 was observed with increasing tumor grades(rs=-0.634,P<0.01) and clinical stages(rs=-0.521,P<0.01). The expressions of Matriptase and HAI-1 in CaP tissues showed negative correlations(rs=-0.712,-0.560,-0.465,respectively,P<0.01). Conclusions The abnormal expressions of Matriptase and HAI-1 proteins may be important events during the progression of CaP in humans. Matriptase and HAI-1 Protein may be used as parameters for assessing the malignancy and prognosis of CaP.

ObjectiveTo observe the growth of BT-325 human glioma cells after interfering volume-regulated chloride channel ClC-2 gene.MethodsTwo expression recombinant vectors of ClC-2 gene were designed and constructed. The primary plasmid, pSUPER.puro-shRNA, and the two recombinant plasmids, pSUPER.puro-shRNA-ClC-21 and pSUPER.puro-shRNA-ClC-22, were transfected into BT-325 cells by LipofectamineTM2000 (Groups: control, PP1 and PP2, respectively). The mRNA expression of ClC-2 gene was detected with reverse transcription polymerasse chain reaction (RT-PCR), the cellular survival was determined with MTT assay, and the cell cycle was measured with flow cytometry (FCM). ResultsClC-2 mRNA expression and the growth of the cells in PP1 and PP2 groups were significantly lower than that of control group. The cell cycle progression was blocked in G1 phase (PP1 and PP2 vs control,P<0.01). ConclusionThe growth of BT-325 human glioma cells is prevented by knockdown of ClC-2 gene expression, which may be one of the novel targets to inhibit growth of human malignant glioma cells.

Objective To investigate the epidemiological characteristics of incipient neonatal hyperbilirubinemia. Methods The clinical data of admitted neonates with hyperbilirubinemia were retrospectively analyzed from June 2012 to May 2013. Results Two hundred and eight-four neonates with hyperbilirubinemia were enrolled and the ratio of male:female was 1.51:1. For the causes of hyperbilirubinemia, the incidences of ABO hemolytic and sepsis were higher in term infants than those in preterm infants, and the incidences of pneumonia, necrotizing enterocolitis and intracranial hemorrhage were higher in preterm infants than those in term infants (P<0.05). Compared with the preterm infants, the term infants had jaundice appearance and peak at earlier time, shorter duration of jaundice, faster decline rate of jaundice, higher levels of albumin and indirect bilirubin at the peak of jaundice (P<0.01). In the term infants, the time of jaundice appearance and peak were earlier in hemolytic group than those in non-hemolytic group (P<0.05). In preterm infants, the peak of transcutaneous bilirubin was higher in hemolytic group than that in non-hemolytic group (P<0.05). Six cases with bilirubin encephalopathy had abnormalities cranial MRI imaging, and the MRI was not entirely consistent with the peak level of bilirubin. Conclusions There are clinical differences between hemolytic and non-hemolytic hyperbilirubinemia in both term and preterm infants.

Background The different incisions in phacoemulsification,including the length,location and shape etc.,can cause surgery-induced astigmatism ( SIA ).But the SIA caused by 2.2 mm,3.0 mm corneal limbal incision after phacoemulsification,especially the change of posterior corneal surface astigmatism is still rarely reported. Objective This study was to investigate the anterior,posterior and total corneal SIA and compare their differences between phacoemulsification and foldable intraocular lens (IOL) implantation with 2.2 mm and 3.0 mm corneal limbal incisions. Methods Seventy-one eyes of 47 cases were randomly divided into two groups with matched age,visual acuity and astigmatism degree.Phacoemulsification and IOL implantation with 2.2 mm incision at the steepest corneal meridian was performed on the patients of 2.2 mm incision group,and the same surgery was adopted with 3.0 mm incision as 3.0 mm incision group.Corneal curvature radius and central corneal thickness were measured by Pentacam at 1 day before surgery and 1 week,1 month and 3 months after surgery respectively.The anterior and posterior corneal surface SIAs were calculated according to the flat axis and steep axis of corneal curvature and the air and the cornea refractive index.Based on the anterior and posterior surface SIAs,the total corneal SIA was then calculated using the vector analysis method.Jaffe/Clayman vector method was used to calculate the anterior and posterior and total corneal SIAs in the different time points,and the differences were compared between the two groups.Oral informed consent was obtained from each subject prior to the trial. Results The mean anterior and posterior surface corneal SIAs appeared to be lower in 2.2 mm incision group compared with 3.0 mm incision group at postoperative 1 day,1 week,1 month and 3 months but were not significantly different among groups at various time points ( anterior SIA:P =0.290 ; posterior SIA:P =0.740 ; total SIA:0.434 ).The mean anterior corneal surface SIAs were significantly lower at the postoperative 3 months than those at postoperative 1 day,1 week in both groups(2.2 mm incision group:P=0.020,0.036;3.0 mm incision group:P=0.006,0.023 ).The posterior corneal surface SIAs were (0.70±0.43 ) D and (0.75 ±0.54 ) D at 1 day in 2.2 mm incision group and 3.0 mm inscision group,respectively,and significantly decreased posterior corneal surface SIAs were found in postoperative 1 week,1 month and 3 months compared with 1 day in both groups ( 2.2 mm incision group:all P =0.001 ; 3.0 mm incision group:P=0.028,0.044,0.032).The total corneal surface SIA showed significant differences between 1 day and 1 week,1 month,3 months after surgery ( 2.2 mm incision group:P =0.015,0.002,0.002 ; 3.0 mm incision group:P =0.049,0.007,0.016 ). Conclusions There are no significant differences in the anterior,posterior and total corneal surface SIAs between 2.2 mm and 3.0 mm incisions after phacoemulsification with IOL implantation.The SIA is gradually reduced with the prolongation of postoperative time.

Aim To establish experimental colitis model in Balb/c mice by Trinitrobenzene Sulfonic Acid (TNBS) enema. Methods Several doses of TNBS instilled into mice colon induced experimental colitis, then mortality rates of mice were observed. Severity of colitis was evaluated by the Disease Activity Index (DAI),Morphologic and Histologic analysis and Myeloperoxidase (MPO) analysis. We also observed the T cell proliferation of spleen. Results It showed that the mice mortality rate was increased when the mice were given the higher dose of TNBS. Most survived mice showed chronic inflammation in reduction colon. Histological examinations of the colon showed multiple erosive lesions and inflammatory cell infiltration composed of macrophages, lymphocytes, neutrophils in lamina propria and beyond mucosal layer. Some colon showed crypt distortion or reduction and high vascular density. Conclusion A TNBS dose of 1.5mg for each mouse was chosen for an appropriate experimental dose since the group showed less mortality rate and appropriate experimental colitis.
