Objective To explore the expression of ribosomal protein L6 (RPL6) in prostate cancer and its clinical sig-nificance. Methods RT-qPCR and Western blot assay were used to measure the mRNA transcription and protein expres-sion levels of RPL6 in prostate cancer tissues (n=80) and adjacent non-cancerous tissues (n=62). The relationship between RPL6 mRNA expression level and clinicopathological factors of prostate cancer was statistically analyzed. Results The mRNA and protein expression levels of RPL6 were significantly higher in prostate cancer tissues compared with those of non-cancerous tissues (P<0.05). There were higher serum expression levels of prostate specific antigen (PSA) and higher Gleason score in prostate cancer tissues. The expression level of RPL6 mRNA was significantly higher in patients with lymph node metastasis and late clinical stage (P<0.05). There were no significant differences in PSA levels between different ages, with or without seminal vesicle invasion and different surgical margin status (P>0.05). Kaplan-Meier survival analysis of biochemical recurrence (BCR)-free survival time showed the significantly lower recurrent rate in patients with high RPL 6 mRNA expression(χ2=4.530,P=0.033). Conclusion The elevated expression of RPL6 may play a role in the development of prostate cancer, and which can be used as a tumor marker to assess the prognosis of prostate cancer.

Objective To investigate the long-term effect of direct percutaneous coronary intervention (PCI) on left ventricular remodeling in patients aged ≥75 years with acute myocardial infarction (AMI).Methods 108 cases of patients with acute myocardial infarction were collected into the study.Direct PCI were completed in patients in PCI group within 12 hours of onset.Patients in non-PCI group received conventional conservative treatment with drugs.Patients were followed up for 0.5-8.0 years,and cardiac function (NYHA) and the detected ultrasonic cardiogram were evaluated during follow-up.Results The 106 patients received follow-up.Two female patients who were not treated with PCI died during follow-up,one patient died of sudden cardiac death and another patient died of severe pneumonia.Compared with non-PCI group,direct PCI group showed that cardiac function (NYHA) grade was lower(t=3.17,P＜0.05),the end-systolic and end-diastolic volume of left ventricle were less(t=3.50、3.90,all P＜0.01),the left ventricular ejection fraction was increased (t=2.00,P＜0.05),the ventricular wall motion index was smaller (t=2.96,P＜0.01).E/A ratio was higher,E wave deceleration time was shorter,and left ventricular mass index was smaller (t=4.04,4.29,4.70,respectively,all P＜0.01),the left ventricular long and short axis diameter were decreased (t=2.30,t=5.53,P＜0.05 or 0.01),and Spherical index was increased (t=2.97,P＜0.01).Conclusions Direct PCI treatment improves chronic ventricular remodeling in elderly patients with AMI and contributes to long-term improvement in cardiac function.

Objective To explore the expression level and significance of the nod-like receptor protein 3 (NLRP3) inflammasome in renal tissue with calcium oxalate stone.Methods 20 kidney specimens were collected as the experimental group from patients with calcium oxalate stone who underwent nephrectomy because of stones in our hospital between January 2008 and December 2014;another 20 renal specimens were get as the control group from patients with renal carcinoma,the renal tissues were obtained 2cm far from the tumor and proved as normal tissue.Immunohistochemical detection was carried out to analyze the expression level of NLRP3,Caspase-1,and IL-1β in the 40 renal samples.Animal experiment:fourteen male SD rats were randomly divided into calcium oxalate stone group and control group.For calcium oxalate stone group we established an ethylene glycol method induced hyperoxaluric rat model featured by crystalline material within tubule lumens;for control group normal feeding was performed.After 6 weeks,all rats were sacrificed,and the kidneys were harvested for further experiments.HE staining and Pizzolato staining were used to detect calcium oxalate crystals within tubule lumens.Western boltting and RT-PCR was applied to detect protein level and mRNA quantity of NLRP3,Caspase-1,and IL-1β from tissue lysates in rat model.Results In renal tissue samples obtained from patients with calcium oxalate stone disease,we demonstrated that the expression level of NLRP3,Caspase-1,and IL-1β were above to the normal renal tissue samples.We established a hyperoxaluric rat model character with crystalline material within tubule lumens examined by renal histology with HE staining and Pizzolato staining.And we detected that the protein and mRNA levels of NLRP3,Caspase-1 and IL-1β were remarkably increased in the lysates from the hyperoxaluric rat model (P ＜ 0.05).Conclusions The NLRP3 inflammasome has overexpression in the renal tissue of patients with calcium oxalate stone as well as in the renal tissue of hyperoxaluric rat,and it provides a new thought to reveal the formation of calcium oxalate stone.

Objective To evaluate the clinical efficiency and complications of deferred limited TURP for treating urinary retention after 125I seed implantation.Methods From Jan.2006 to Jan.2014,36 prostate cancer patients with severely dysuria or retention were performed with deferred limited TURP 6 months after 125I seed implatation.The average age was 66 (57 to 82) years.The average PSA was 8.5 (3.5 to 25.6) μg/L before seed implantation.The average prostate volume was 78 (45 to 110) ml.Before limited TURP,the average IPSS was 16.5 (13 to 32),the average QOL score was 5.5 (5 to 6),the Qave was 5.6 (2 to 9) ml/s,the average PVR was 285 (120 to 550) ml.The urination state,QOL and complications were evaluated the second day after catheter removal and one,three and six months after limited TURP.Results Limited TURP was successfully performed in all 36 patients.The average operation time was 45 (35 to 60) min.The average fellow-up time was 42 (6 to 84) mon.The second day after catheter removal,the average IPSS was 4.5 (3 to 6),the average QOL score was 2 (1 to 3),the Qave was 14.5 (12 to 21) ml/s,the average PVR was 35 (20 to 50) ml.One month later,the average IPSS was 3.5 (2 to 5),the average QOL score was 2.0 (1 to 3),the Qave was 15.5 (12 to 23) ml/s,the average PVR was 30 (20 to 40) ml.Three months later,the parameters continued to improve and stabilized.The second day after catheter removal and one,three and six months after limited TURP,all parameters had significant improvement compared with those before limited TURP with statistical significance (P ＜ 0.05).Four cases had mild incontinence,no case had urethral ischemia and necrosis.Conclusions 6 months after 125I seed implatation,prostate cancer patients with severely dysuria or retention can be safely and effectively treated with limited TURP.

Objective To observe the effect of MAP4K4 targeted shRNA on biological characteristics such as proliferation,invasiveness,and apoptosis in human bladder cancer cell.Methods Differentially expressed genes was screened out through cDNA microarray analysis in 5 pairs of fresh-frozen muscle-invasive bladder cancer(MIBC) and adjacent normal tissue obtained from radical cystectomy.Combining the results of genechip and literature review,MAP4K4 was picked up for further analysis.To verify the result of microarray analysis,16 pairs of fresh muscle-invasive bladder cancer (MIBC) and adjacent tissues were assessed for the expression of MAP4K4 mRNA and protein through RT-PCR,qRT-PCR and Western-blot.T24 cell line was stably trasfected with MAP4K4 targeted shRNA and control shRNA,respectively.The effects of MAP4K4 silencing on proliferation,invasiveness and apoptosis of T24 cells transfected with MAP4K4 targeted shRNA and control shRNA were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT),transwell and flowcytometry (FCM) assay.Results MAP4K4 was overexpressed in muscle invasive bladder cancer than in normal tissue.Down regulation of MAP4K4 expression decreased bladder cancer cell proliferation(MAP4K4-targeted versus control,P＜0.001),invasiveness(MAP4K4-targeted versus control,P=0.004)and promoted cell apoptosis(MAP4K4-targeted versus control,P=0.023).Conclusions MAP4K4 is overexpressed in muscle invasive bladder cancer than in normal tissue.Down-regulation of MAP4K4 expression inhibits the invasive ability of bladder cancer.Therefore,MAP4K4 might be a potential therapeutic target for bladder cancer.

Objective To understand the genetic characteristics of Enterovirus 71 ( EVT1 ) circu-lating strains of Guangdong province in 2008. Methods We isolated an EV71 strain from the fatal case of the hand, foot and mouth disease during an epidemic of Guangdong in 2008. Its complete genome was se-quenced and analyzed comparatively. Results The results showed that the full length of EV71 GDFS-3 ge-nome( not including poly A tail ) is 7405 bp. No insertion or deletion is detected in the coding region. There are several insertions and deletions in 5'and 3'UTR. Phylogenetic analysis of GDFS-3 and reference strains showed GDFS-3 strain shares the highest nueleotide homology with TW984 strain(96.0% ) but low homology with SIN5865, MS and BrCr( about 81.0% ). GDFS-3 strain also shares the highest amino acid homology with TW984 strain(99.0% ). It clustered with reference strains of CA subgenotype in the phylogenetie tree. The nucleotide identity with CA reference strains is 91.0% -95.0%. Conclusion The phylogenetic analysis based on the entire genome demonstrates that GDFS-3 strain has the nearest genetic relationship with TW984 strains ( isolated in 2004). GDFS-3 may belong to the same subgenogroup ( CA ) with Taiwan predominant strains. Otherwise,Some mutations in 5'UTR of EV71 may play the very important role in heightened viru-lence.

Objective To analyze the genetic characterization(evolution, antigenicity, enzyme activity sites and glycosylation sites)of the neuraminidase(NA)gene of the novel influenza virus A/H1N1 in 2009 pandemic in Guangdong Province. Methods The viral RNA was extracted from 69 isolates of influenza virus A/H1N1 from patients in 2009 pandemic in Guangdong Province. NA gene fragments were amplified by reverse transcription polymerase chain reaction (RT-PCR) and sequenced. The other 52 NA gene sequences of influenza virus A in different years and different regions were retrieved from GenBank. The analysis of evolution and amino acid sequences were analyzed by MEGA 4.0 software. Results The homology of 2009 novel H1N1 influenza viruses in Guangdong and avian H5N1 influenza virus strains was high(＞85 % ). The amino acid distributions of potential antigenic sites were identical. The enzyme activity sites of NA genes of all virus strains were strictly conserved, which had eight glycosylation sites. But there were amino acid substitutions in 5 glycosylation sites, while it was identical with the 2001 avian H5N1 influenza virus. Conclusion The NA genes of 2009 novel H1N1 influenza viruses in Guangdong are high homologous with avian H5N1 influenza virus and the viral specific binding sites of neuraminidase inhibitor are not changed.
