Objective To explore the effect of continuing care on the intermittent catheterization compliance of patients with neurogenic bladder. Methods From January to December, 2015, 60 patients with neurogenic bladder after spinal cord injury receiving intermittent cathe-terization were randomly assigned to control group (n=30) and intervention group (n=30). The control group received routine discharge in-struction, while the intervention group received continuing care in addition. The intermittent catheterization compliance, residual urine vol-ume, urinary tract infection and quality of life were assessed at discharge and three months after intervention. Results After intervention, the intermittent catheterization compliance was better in the intervention group than in the control group (χ2=7.500, P=0.006). The residual urine volume significantly decreased in both groups (t>12.040, P<0.001), and was less in the intervention group than in the control group (t=-2.190, P=0.032), as well as the urinary tract infection rate (χ2=10.800, P=0.001). The score of quality of life increased significantly after intervention in both groups (t>4.572, P<0.001), and was higher in the intervention group than in the control group (t>5.505, P<0.001). Con-clusion Continuing care could improve the intermittent catheterization compliance, reduce the residual urine volume and the urinary tract in-fection rate, and improve the quality of life in patients with neurogenic bladder after discharge.

RESULTS Comparing with the matched group,the infection rate of the experimental group was much lower after the actions.The actions prevented the increase of infection effectively. CONCLUSIONS Building and carrying out the systems are proved to be important measures to decrease the catheter infection and ensure the quality of life among patients during the therapy in hospital.

Abstract: Objective　To evaluate the effects of sunitinib on Japanese encephalitis virus (JEV) infection in vitro and vivo. Methods　The 4-week-old BALB/c mice infected with JEV by intraperitoneal injection. The infected mice were treated with sunitinib for 5 days and 10 days respectively. After that, the change of weight and survival rate were evaluated continuously. The viral load variation in mice brain were detected by qRT-PCR. Indirect immunohistochemical staining assay (IFA) was used to detect the number and distribution of CD4+/CD8+T cells in mouse brain. IFA was also used to observe the expression of virus E protein in the brain of mice. Vero cells were infected with JEV in vitro and given a certain concentration of sunitinib to observe the cell survival status. The expression of virus E protein in cells was detected by IFA. Results　Continuous administration of sunitinib significantly improved the survival rate of infected mice. Survival rate and body weight changes showed that the 5-day's administration strategy was significantly better than the 10-day's administration strategy. The treatment of sunitinib decreased the infiltration of CD4+/CD8+T cells in the brain and reduced the changes of vascular sleeve. However, the variation of viral load and E protein expression in brain were not obvious. The cytopathic effect (CPE) of infected Vero cells were slightly relieved after giving sunitinib, and the expression of E protein was also slightly changed. Conclusion　Sunitinib can significantly reduce the mortality of infected mice, and the 5-day's administration strategy is significantly better than the 10-day's administration strategy. Sunitinib decrease T lymphocyte infiltration in brain of mice, relieve the encephalitis symptoms ,and prolonged the life of mice.

Background:Pulsed radiofrequency (PRF),as a non-invasive treatment of neuropathic pain (NP),has been widely administered clinically.Previous studies have shown that PRF has the potential to improve hyperalgesia in animal models of NP.However,there have been few reports to clarify whether the mechanism of PRF treatment of NP involves intervention in the expression of substance P (SP).Therefore,this study administered PRF treatment to chronic constriction injury (CCI) model rats and observed the sciatic nerve mechanical pain threshold and SP expression in the spinal cord to explore the mechanism of PRF treatment.Methods:A total of 96 Sprague-Dawley rats were randomly divided into the sham-surgery-sham-treatment group (S-S group),the sham-surgery-PRF group (S-P group),the CCI-sham-treatment group (C-S group),and the CCI-PRF group (C-P group).The C-S group and the C-P group underwent sciatic nerve CCI,while the other groups received a sham operation.At 14 days after the operation,the C-P group and the S-P group were treated with PRF for 300 s.We recorded the hindpaw withdrawal threshold (HWT) and the thermal withdrawal latency (TWL) of rats in the various groups at baseline,before treatment (0 days),and at 1,7,14,and 28 days after treatment.L4 to L6 spinal cord tissues were taken before treatment (0 days) and 1,7,14,and 28 days after treatment.The transcription and translation of SP were measured by quantitative polymerase chain reaction and Western blotting,respectively.Results:The HWT and the TWL in the C-P group 28 days after PRF treatment were significantly higher than those in the C-S group (95％ confidence interval [CI]:5.84-19.50,P ＜ 0.01;95％ CI:2.58-8.69,P =0.01).The expression of SP in the C-P group 28 days after PRF treatment was significantly lower than that in the C-S group (95％ CI:1.17-2.48,P ＜ 0.01).Contusions:PRF may alleviate CCI-induced NP by down-regulating the expression of SP in the spinal cord of CCI model rats.

OBJECTIVETo explore the role of Compound Danshen Injection (CDI) in regulating the expression of aquaporin 3 (AQP3) in human amnion epithelium cells (hAECs), and to study the relation between c-Jun N-terminal kinase (JNK) signal pathway and AQP3.

METHODShAECs were isolated and primarily cultured from term pregnancy with normal amniotic fluid volume and from term pregnancy with oligohydramnios, and then hAECs were further divided into four groups, i.e., the blank control group (A), the SP600125 group (B), the CDI group (C), and the SP600125 +CDI group (D). The cell viability was measured by cell counting kit-8 assay (CCK-8). The expression of total JNK, phosphorylated JNK, and AQP3 were determined by Western blot.

RESULTS(1) In hAECs with normal AFV or with oligohydramnios: There was no statistical difference in the cell viability or the expression of total JNK among the 4 groups (P > 0.05). But there was statistical difference in the expression of p-JNK (P < 0.05). Compared with A group, the expression of p-JNK was obviously down-regulated in B group, but obviously up-regulated in C group (P < 0.05). The expression of p-JNK was significantly lower in D group than in C group, but higher than that in A group or B group (P < 0.05).The AQP3 expression in the hAECs with normal amniotic fluid volume of C group and D group were higher than that in the A group (P < 0.05). However, there was no statistical difference in the AQP3 expression between C group and D group (P > 0.05). In hAECs with oligohydramnios, the expression of AQP3 obviously decreased in B group, but up-regulated in C group (both P < 0.05). The expression of AQP3 was lower in D group than in C group, but higher than in B group (P < 0.05).

CONCLUSIONCDI could regulate the AQP3 expression in hAECs with oligohydramnios via activating the JNK signal pathway.

Objective To study the different expressions of receptor activator of nuclear factor-kappa B ligang(RANKL) mRNA in spleens of rats fed with diet of low calcium and high fluoride. Methods A 2× 2×2 factorial design was used and the factors were calcium, fluoride and action time. In the design, 40 Wistar rats [average body mass(118.9±13.5)g] were divided into four groups randomly by weight: control with normal diet (0.790%, calcium), low calcium group with low calcium intake(0.063%, calcium), high fluoride group with normal diet and high fluoride intake(100 mg/L, fluoride) and low calcium and high fluoride group with low calcium and high fluoride intake. After 4 and 8 months, 5 rats of each group were sacrificed and total RNA was extracted from spleen. And the expression levels of RANKL mRNA were determined by reverse transcription polymerase chain reaction (RT-PCR). Results At time of 4 months, the expression level of RANKL mRNA was 0.13± 0.05,0.13± 0.03,0.17±0.02,0.27± 0.05 and at time of 8 months, it was 0.11 ± 0.01,0.16 ± 0.02,0.16± 0.03,0.36 ± 0.07 in control group, low calcium group, high fluoride group, low calcium with high fluoride group, repectively. The factorial design AVONA showed that low calcium and high fluoride had significant effects on RANKL mRNA expression(F = 40.224,56.679, all P < 0.05) while action time had not(F = 2.850, P > 0.05 ). The interactions of low calcium with high fluoride or high fluoride with action time were signifieant(F = 7.247, 18.789, all P < 0.05) while the interaction of high fluoride with action time was not(F = 1.751, P > 0.05). Conclusions Low calcium alone or high fluoride alone or low calcium with high fluoride or low calcium with action time can increase the the RANKL mRNA expression level. High fluoride does not affect the RANKL mRNA level as the action time is prolonged.

Objective To investigate the correlation between the biomarkers related to radio-sensitivity and preoperative radiotherapy in rectal cancer patients, and to establish a logistic regression model to predict the effect of the preoperative radiotherapy through detecting the expression levels of the molecular markers. Methods 33 patients with rectal cancer who received preoperative radiotherapy from January 2010 to January 2015 were retrospectively analyzed. Patients' information was also collected including the serum level of carcino-embryonic antigen (CEA), the immune-histochemical expression levels of vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), thymidylate synthase (TS) and Ki-67, and image data (CT or magnetic resonance imaging) before radiotherapy, preoperative clinical staging and the postoperative pathologic staging. According to the postoperative pathological remission, the treatment effects of preoperative radiotherapy included effective (CR+PR) and ineffective (PD+SD) were evaluated. The relationship between these molecular markers and the curative effect of preoperative radiotherapy was analyzed by logistic regression analysis using SPSS v17.0 software, and a logistic curative effect prediction model was established. Results As a result of single factor and multiple factors logistic binary regression analysis, CEA, VEGF and Ki-67 were recognized as the interested factors for the radio-sensitivity predicting in patients with rectal cancer who received preoperative radiotherapy. A molecular markers predictive model for radio-sensitivity in preoperative radiotherapy in rectal cancer is as follow: log P=1.700-0.276×CEA-0.238×VEGF-0.135 ×EGFR+1.377 ×TS+0.080 ×Ki-67. Serum CEA level and the expression of VEGF might associate with radio-resistant, and the expression of Ki-67 might associate with better reaction to preoperative radiotherapy. Conclusion The levels of serum CEA, VEGF and Ki-67 may be the predictors of radio-sensitivity in rectal cancer patients who received preoperative radiotherapy.
