Objective:To investigate whether the risk of intravesical recurrence increases in patients with upper urinary tract urothelial carcinoma (UUT-UC) and diabetes mellitus (DM) after radical nephroureterectomy (RNU) with bladder cuff excision. Methods:We ret-rospectively analyzed the clinicopathological data of 282 UUT-UC patients with no history of bladder neoplasm and who underwent RNU with bladder cuff excision in the Second Hospital of Tianjin Medical University from January 2005 to December 2013. The recurrence-free survival (RFS) and cancer-specific survival (CSS) were compared between the non-diabetic (233 patients) and diabetic (49 patients) patients. The factors influencing intravesical recurrence in patients with UUT-UC after RNU were analyzed. These factors included age, DM, pathologic grade, and stage. Results:Among the 282 patients included in the study, 80 (28.4%) patients developed intravesical recurrence during the median fol ow up of 41 months, and the median time to recurrence was 11 months. Non-diabetic patients had a significantly longer duration of bladder neoplasm RFS than diabetic patients (P=0.013). Multivariate analysis using Cox's regression model indicated that DM (P=0.014), renal pelvis and ureter tumor (P=0.001), and postoperative chemotherapy (P=0.024) were independent influential factors for intravesical recurrence in patients with UUT-UC after RNU with bladder cuff excision. Conclusion:DM posed an increased risk for intravesical recurrence after RNU with bladder cuff excision in patients with UUT-UC. Therefore, these patients need to be closely monitored, and their blood glucose must be controlled.

Objective To explore the suicide ideation and related factors in elderly with depressive disorder.Methods A sample of 60 old patients meeting the criteria of ICD-10 for depressive disorder and 60 normal controls were assessed by the Self-rating Idea of Suicide Scale(SIOSS),Trait Coping Style Questionnaire (TCSQ),Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS) and Pittsburgh Sleep Quality Index(PSQI).Results The score of despair factor,optimistic factor,sleep factor,conceal factor and total score of SIOSS in patients with depressive disorders (6.22±3.28,2.43± 1.47,1.87± 1.58,1.17± 1.1 1 and 10.51±4.91,respectively) were significantly higher than those of normal controls(t=5.83-14.03,P＜0.01).The scores of SIOSS in patients were significantly positively related with the scores of SAS,SDS,PSQI and N C (r=0.311-0.792,all P＜0.05),but negatively related with the scores of PC(r=-0.761,P＜0.01).Moreover,regression analysis showed that the suicide ideation was increased in accordance with serious depression,anxiety,sleep quality,higher level of education and decreased ability to positive response in elderly with depressive disorder(R 2=0.853,F=62.768,P＜0.01).Conclusion The suicide ideation in elderly with depressive disorder is more serious than that of normal people,and may be influenced by depression,anxiety,sleep quality and coping style.

Objective To study the effect of ?-scretase substrate-base peptide(BACEsp) on cellular model of Alzheimer's disease(AD).Methods The cellular model of AD established with neuroblastoma cell SK-N-SH induced by amyloid precursor protein(APP) was infected with the supernatants including recombinant retrovirus pLXSN-BACEsp.MTT assay was used to test cell viability and immunocytochemistry was used to observe APP expresion in cells before and after BACEsp treatment.Results Cell viability and APP expression in the cells that had been first infected by recombinant retrovirus pLXSN-BACEsp were apparently higher than those only transfected by APP and last infected by recombinant retrovirus pLXSN-BACEsp.Conclusion BACEsp has an obviously protective effect on APP-induced neuron toxicity of cellular model of AD.

The rutile structure titanium oxide (Ti-O) film was prepared on the pure titanium material TA2 (99.999%) surface by the magnetic filter high vacuum arc deposition sputtering source. The method can not only maintain the material mechanical properties, but also improve the surface properties for better biocompatibility to accommodate the physiological environment. The preparation process of the Ti-O film was as follows. Firstly, argon ions sputtered to the TA2 substrate surface to remove the excess impurities. Secondly, a metal ion source generated Ti ions and oxygen ions by the RF discharge. Meanwhile a certain negative bias was imposed on the sample. There a certain composition of Ti-O film was obtained under a certain pressure of oxygen in the vacuum chamber. Finally, X-ray diffraction was used to research the structure and composition of the film. The results showed that the Ti-O film of the rutile crystal structure was formed under the 0.18 Pa oxygen partial pressure. A Nano scratch experiment was used to test the coating adhesion property, which demonstrated that the film was stable and durable. The contact angle experiment and the platelet clotting experiment proved that the modified surface method had improved platelet adhesion performance, and, therefore, the material possessed better biocompatibility. On the whole, the evaluations proved the modified material had excellent performance.

Objective Through the investigation and analysis to "Chinese Medical Digest" and its relative periodicals to get a general idea of the survival and situation of these periodicals and to establish the pattern for their survival and development. Methods Such methods as telephone consultation, questionnaire survey, interview, and conference discussion were adopted to collect the relative information of medical digest periodicals and thus an analysis was made upon it. Results There were 18 kinds of "Chinese Medical Digest" periodicals originally. Of all these 18 kinds of the periodicals, 6 kinds are still publishing, 10 kinds have transferred its nature to first-hand literature periodical, and 2 kinds have ceased their publishment. Conclusion As a result of the computer, the network and the full text database development, the survival of medical digest periodicals are endangered. However, regarding to the different domain of subject, different reforming measures should be taken.

Objective To investigate the spatio-temporal expression of P2X3 receptor ( P2X3R) in rats with diabetic mechanical allodynia ( DMA ) .Methods DMA model in rats was induced by intraperitoneal injection of streptozocin ( STZ) .The von Frey filaments were applied to identify the changes of the paw withdrawal threshold ( PWT) in DMA rats.Immunofluorescence was employed to detect the spatio-temporal expression of P2X3R in the spinal dorsal horn (SDH), dorsal root ganglion (DRG) and hind paw skin on different time points after intraperitoneal injection of STZ , respectively.The protein expression of P2X3R in SDH and DRG was further semi-quantitatively analyzed by Western blotting.Results Compared with control group , intraperitoneal injection STZ induced significant mechanical allodynia indicated by the reduced PWT from 7 days, and which reached the peak on 14d and maintained to 28days (P<0.05). The expression of P2X3R in DRG neurons was significantly increased on 14 days and 21 days (P<0.05), while that in SDH and skin was markedly increased on 21 days and 28 days, compared with control group (P<0.05).Conclusion With the progress of DMA, the expression of P2X3R was significantly increased in the SDH, DRG and skin, which was almost parallel with the mechanical allodynia , but the changes in SDH and skin were 1 week later than that in DRG .These results suggest that P2X3R may play a key role in the maintenance of the DMA .

Objective To compare the outcomes in pregnancy between the patients with poor ovarian reservation receiving ultra-long-term down-regulation protocol and modified long-term protocol who were undergoing in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI),aiming at screening an optimal ovulation induction scheme.Methods Retrospectively analyzed the clinical data of 78 patients with poor ovarian reservation who underwent IVF or ICSI from October 2010 to July 2012.Forty-three patients received modified long-term protocol treatment (group A),with 0.375 mg long-acting triptorelin during the midluteal phase as well as superovulation start date plus alarelin (0.15 mg/d) to intramuscular injection of human chorionic gonadotropin (HCG) day.Thirty-five patients received ultra-long-term down-regulation protocol (group B).Triptorelin was injected intramuscularly in mid-luteal phase twice followed by triptorelin at a dose of 1.2-1.3 mg after 28 days of long-acting triptorehn treatment (1.5 mg).Gonadotropin was started 16 days after the second GnRHa injection.The dose of Gn,number of oocytes retrieved,number of embryos available,implantation rate,pregnancy rate,and miscarriage rate were recorded and compared between the two groups.Results There was no significant difference between the two groups in the mean age of participants,basal follicular number,FSH,the dose of Gn used,number of oocytes retrieved,number of embryos available,number of implanted embryos,Pregnancy rate(32.56％ vs.34.29％),implantation rate(18.75％ vs.20.97％) and miscarriage rate (0 vs.8.33％)(P ＞ 0.05).Conclusion No significant difference was found between the two groups in clinical pregnancy rate and abortion rate.But modified long-term protocol needs a shorter treatment period than the ultra-long-term protocol.Moreover,it reduces the risk of excessive suppression of pituitary function.Therefore,it takes advantages over the other in the clinical application.

Objective To investigate the relationship between adiponectin combined with the ultrasound blood flow index of the umbilical artery and perinatal outcome in women with severe preeclampsia. Methods Placental tissues were obtained from normal term pregnancies (control group, n=50) and severe preeclampsia patients (PE group, n=50) in Third Affiliated Hospital of Zhengzhou University from February 2014 to October 2014. The expression of adiponectin was examined using immunohistochemical methods and real-time polymerase chain reaction. The umbilical artery was measured by color Doppler, and the umbilical artery systolic/diastolic ratio (UA-S/D), umbilical artery resistance index (UA-RI) and umbilical artery pulsatility index (UA-PI) were determined. The relationship between the expression of adiponectin in placental tissues, UA-S/D and perinatal outcome were analyzed. The data were analyzed using two dependent-sample t test, the log-rank test and Spearman correlation analysis. Results Compared with the control group, infants in the PE group had lower birth weight and placental weight, shorter height, and greater umbilical artery indices including UA-S/D, UA-RI and UA-PI (all P<0.05). The expression of adiponectin and its mRNA in placentae of the PE group was significantly higher than that of the control group (adiponectin: 0.326±0.011 vs. 0.116±0.011, t=99.144, P=0.000;mRNA:4.18±1.80 vs. 1.00±0.51, t=11.985, P=0.000). UA-S/D had a negative correlation with birth weight, onset gestational age and gestational age at birth (r= - 0.897, - 0.469 and - 0.524, all P<0.01). The expression of adiponectin mRNA had a negative correlation with birth weight, onset gestational age, and gestational age at birth (r=-0.580,-0.407 and-0.449, all P<0.01). The expression level of adiponectin had positive correlations with body mass index of the mothers and the UA-S/D (r=0.261 and 0.788, both P<0.01). Conclusions The expression of adiponectin in placental tissues and blood flow index of the umbilical artery both increase in severe preeclampsia, and are associated with poor perinatal outcome.
