Fluorescence in situ hybridization (FISH) is a kind of technique that uses fluoreseently la-beled DNA probes to assess cells for genetic alterations. UroVysion is a technique that uses FISH to detect bladder cancer in the voided urine by four fluorescently labeled DNA probes to the pericentromeric regions of chromosomes 3 ( CEP3 ) ,7 (CEPT), and 17 (CEP17) and to the 9p21 locus ( LSI 9p21 ) location of the p16 tumor suppressor gene. It is reported that sensitivity of FISH was higher than cytology for the detection of all stages and grades of bladder cancer. FDA has approved UroVysion for the detection of recurrent bladder cancer in voided urine specimens from patients with a history of bladder cancer in the year 2001 and from pa-tients with gross or microscopic hematuria but no previous history of bladder cancer in the year 2005. Fur-thermore, UroVysion can benefit the assessment of bladder cancer patients receiving BCG treatment.

Objective To investigate expression of elastin,lysyl oxidase (LOX)and elafin in cardinal ligament of women with pelvic organ prolapse(POP) so as to determine their contributions to POP.Methods The cardinal ligament samples were obtained from 60 POP subjects and 60 non-POP control women undergoing hysterectomy.RT-PCR was used to verify the mRNA level of elastin,LOX and elafin.The protein concentration of the three genes was determined by western blotting technique,electrophoretic separation and quantification.Results The premenopansal and postmenopausal POP groups demonstrated significantly decreased expressions of elastin in cardinal ligament both in mRNA and protein levels than control group (mRNA 0.42±0.22,0.26±0.20 versus 0.79±0.30,0.63±0.23 ; protein 0.44±0.32,0.20±0.19 versus 0.89±0.27,0.78±0.25; P＜0.05).There was an identical tendency in the expression of LOX (mRNA 0.37±0.18,0.20±0.14 versus 0.65±0.22,0.53±0.20; protein 0.45±0.27,0.26±0.21 versus 0.85±0.39,0.69±0.31 ; P＜0.05).In POP group,the mRNA and protein levels of elastin and LOX in postmenopansal patients were significantly lower than premenopansal patients (P＜0.05).Inversely,POP group demonstrated an increased expression of elafin in cardinal ligament both in mRNA and protein levels than corresponding control group (mRNA 1.33±0.35,1.47±0.37 versus 0.62±0.25,0.55±0.24; protein 0.85±0.30,0.76±0.35 versus 0.21±0.15,0.29±0.22; P＜0.05). There was no significant difference in the expression of elafin between premenopansal and postmenopausal POP groups either in mRNA or protein levels(P＞0.05).There was a positive correlation between elastin and LOX both in mRNA and protein levels in POP group(r=0.9959,0.9708; P＜0.05),but there was no correlation between elastin and elafin(r=-0.0402,-0.0365;P＞0.05).Conclusions The results suggest that the decreased expression of elastin and LOX and the increased expression of elafin in the cardinal ligaments may contribute to POP.

Objective To investigate the effects of irbesartan hydrochlorothiazide combined with candesartan cilexetil in the treatment of elderly patients with hypertension and its protective effect on cardiac function.Methods 180 elderly patients with hypertension were selected,and they were randomly divided into observation group and control group according to the digital table,90 cases in each group.The observation group was given irbesartan hydrochlorothiazide combined with candesartan treatment,the control group was given candesartan.The heart function improvement after treatment,clinical efficacy and patients in hospitalization,complications,critical events and new death of the two groups were compared.Results After treatment,the heart rate,EVDD,SBP and other indicators of the two groups declined,which of the observation group[(56.14 ± 6.15)mm,(112.12 ± 20.12)mmHg,(70.45 ± 8.69/min)]were lower than the control group[(60.12 ± 6.78) mm(119.45 ± 21.45) mmHg,(82.12 ± 9.12/ min)],there were significant differences between the two groups (t1 =4.124,P =0.000;t2 =2.364,P =0.019;t3 =8.788,P =0.000).The total effective rate of the observation group was 93.33％,which was higher than 74.44％ of the control group,there was significant difference between the two groups (x2 =11.879,P =0.000).Conclusion Irbesartan hydrochlorothiazide combined with candesartan in the treatment of elderly hypertensive patients can effectively improve the heart function of patients,has significant effect.

Objective To evaluate the role of autophagy in inflammatory response in the lungs of silicosis rats. Methods The specific pathogen-free healthy male Wistar rats were randomly divided into four groups with 10 rats in each group. The rats in the control group were given an equal volume of 0.9% sodium chloride solution; all rats in the silicon dioxide (SiO2 ) group, the SiO2 + 3-methyladenine (3-MA) group, and the SiO2 +rapamycin (RAPA) group were given a mass concentration of 0.05 mg/L of SiO2 suspension (1.0 mL/rat) to establish a rat model of silicosis using non-exposed tracheal instillation method. Two days before SiO2 exposure, the rats in SiO2 +3-MA group were intraperitoneally injected with 3-MA at a dose of 2.5 mg/kg body weight. The rats in the SiO2 +RAPA group were intraperitoneally injected with a dose of RAPA 1.0 mg/kg body weight, once a day, and once every other day after modeling, for a total of 10 injections. The pathological changes in the lung tissue of the rats in each group were evaluated using hematoxylin-eosin and Masson staining. The relative expression levels of transforming growth factor-β (TGF-β) , interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the lung tissue of the rats in each group were detected using enzyme-linked immunosorbent assay. The relative expression levels of microtubule-associated protein 1 light chain 3 (LC3) and yeast autophagy-related gene 6 (Beclin1) in lung tissue of rats in each group were detected by Western blotting. Results The pathological observation of rat lung tissue showed that scattered inflammatory nodules and interstitial inflammatory cells were found in the lung tissue of the rats in the SiO2 group. In the SiO2 +3-MA group, the inflammation in the lung tissue was more severe and the alveolar cavity had viscous secretions. The rats in the SiO2 +RAPA group had less inflammation and smaller inflammatory nodules than the SiO2 group. Compared with the control group, the TNF-α, IL-1β, TGF-β, Beclin1 protein relative expression levels and LC3 Ⅱ/Ⅰ ratio in the lung tissue were increased in the SiO2 group (all P<0.05). Compared with the SiO2 group, the relative expression levels of TGF-β and TNF-α in the lung tissue of the rats increased (all P<0.05), and the ratio of LC3 Ⅱ/Ⅰ and Beclin1 protein relative expression decreased in the SiO2+3-MA group (all P<0.05). Compared with the SiO2+ 3-MA group, the relative expression levels of TNF- α, IL-1β and TGF- β in the lung tissue of the SiO2 +RAPA group were decreased (all P<0.05), and the LC3Ⅱ/Ⅰ ratio and the relative expression level of Beclin1 protein were increased (all P<0.05). Conclusion Autophagy occurs when inflammatory reaction occurs in the lungs of silicosis model rats; autophagy has inhibitory effect on pulmonary inflammation.

OBJECTIVE:To investigate the characteristic and regularity of antineoplastics-induced ADR,and to provide refer-ence for safety use of antineoplastics in clinic. METHODS:In retrospective study,309 cases of antineoplastics-induced ADR col-lected from a special hospital during Jan.-Dec. 2015 were summarized and analyzed statistically. RESULTS:Among 309 ADR cas-es,female (58.25％) was more than male (41.75％). The patients aged more than 40 years old occupied the highest proportion (78.64％). Main route of administration was intravenous dripping(94.82％). There were 225 cases of severe ADR(72.82％). To-tal 268 cases were improved after drug withdrawal or treatment(86.73％). A total of 24 kinds of antineoplastics were involved in 309 ADR cases;most of ADR were induced by docetaxel,followed by cisplatin,cyclophosphamide. Most common organs/system involved in ADR was hemopoietic system (64.24％),main clinical manifestation was myelosuppression. CONCLUSIONS:It is necessary to strengthen ADR monitoring,prevent,discover and treat antineoplastics-induced ADR timely,in order to reduce the harm to the patients and ensure the safety and effectiveness of drug treatment.

Objective To investigate the potential of AFP-targeted ultrasmall superparamagnetic particles of iron oxide (USPIO) molecular probe in specific detection of hepatocellular carcinoma (HCC) with MRI.Methods The targeted probe was synthesized by conjugating AFP antibody with modified USPIO.Two groups treated with AFP-USPIO and USPIO were set up in the study.The HepG2 cells were incubated with AFP-USPIO or USPIO (100 μg/ml) respectively with the dosage of 50 μ1,100 μl or 150 μl for 4 hours,followed by MR imaging in vitro.The signal-noise ratio (SNR) of the cells on T2-weighted image (T2WI) was measured.The rat models with orthotopic HCC were divided into two groups with 5 rats for each group at random.Pre-and post-contrast enhanced (after 1 hour) MR imaging were performed with caudal vein injection at a dosage of 20μg/ml.The contrast noise ratio (CNR) on T2WI and the difference of CNR between pre-and post-enhancement or between both groups were calculated.The relationship of SNR or CNR with the iron particles in cells or tumors was confirmed by Prussian blue iron staining.Results Cytology experiment showed the SNR in both groups was decreased with the increase of the dosage of AFP-USPIO or USPIO,indicating statistically significantdifference in SNR among three different doseage groups (P＜0.05).Prussian blue iron staining showed that the iron particles in cells were increased with the increase of AFP-USPIO dosage,and was negatively correlated with SNR (P=0.00,r=-0.926).However,the iron particles were less in cells in USPIO group.The CNRs of liver tumors in Wistar rat of pre-and post-AFP-USPIO injection were 2.05±0.88 and 0.96±0.31 respectively,indicating a significant difference (P=0.028,t=3.380).However,the CNRs in USPIO group,2.25±1.50 and 2.57±1.49,showed no statistical difference (P=0.275,t=1.263).The CNR after enhancement also had a statistical difference between both groups(P=0.042,t=3.487).Pathological results confirmed more iron particles in tumor tissues in AFP-USPIO group,whereas less in USPIO group.Conclusion AFP-USPIO molecular probes can initiatively target to the HepG2 cells and the liver cancer of rat models expressing AFP,which may help to achieve the specificity of MR imaging in the diagnosis of HCC.

Objective:The benefits of postoperative adjuvant therapy method for low-risk early-stage cervical squamous cell carcinoma were investigated. Methods:A total of 133 patients with low-risk early-stage cervical squamous cell carcinoma were treated at Shandong Cancer Hospital&Institute from February 2008 to March 2012. All patients received adjuvant therapy:42 were treated with pelvic ra-diotherapy (RT), 47 were treated with adjuvant chemotherapy (CT)+intracavitary radiotherapy (ICRT), and 44 were treated with concurrent chemoradiation (CCRT). Disease-free survival (DFS) and complications of the therapy were evaluated. Results:No significant differences in DFS were observed in the patients treated with RT, CT+ICRT, and CCRT (P>0.05), and the three-year DFS rates were 94.0%, 93.4%, and 97.6%, respectively. The frequencies of grade III to IV acute toxicities were significantly higher in patients treated with CCRT (34.1%) than in those treated with RT (9.5%) or CT+ICRT (16.7%) (P<0.05). No statistically significant difference was observed between the RT group and the CT+ICRT group (P>0.05). Grade I to II late toxicity was significantly more frequent in the CCRT (25%) and RT (19.0%) groups compared with the CT+ICRT group (4.3%) (P>0.05), but no statistically significant differences were observed between the CCRT and the RT groups (P>0.05). Conclusion:CT+ICRT or RT has a three-year DFS rate equivalent to CCRT but with fewer therapy com-plications for low-risk early-stage cervical squamous cell carcinoma.
