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.

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.

OBJECTIVETo explore the effect of Danggui Yinzi (DY) on delayed allergy in model mice with qi-blood deficiency syndrome (QBDS).
METHODSQBDS model was established in 48 Kuming mice of SPF grade by using reserpine and acetophenone hydrazine. Forty of them were then randomly divided into the model group, the loratadine group, the high dose DY group, the middle dose DY group, and the low dose DY group, 8 in each group. Another 8 in line with the same standard were recruited as a blank group. Mice in high, middle, and low dose DY groups were administered with DY concentrated solution at 60, 30, 15 g/kg by gastrogavage. Mice in the loratadine group were administered with loratadine solution at 1.66 mg/kg by gastrogavage. Equal volume of normal saline was administered to mice in the model group and the blank group by gastrogavage. All medication was given once per day for 1 successive week. Except those in the blank group, the rest mice were evenly smeared with 1% DNCB solution on the abdomen. Five days after skin allergy, 1% DNCB solution was smeared to right ear of all mice to stimulate allergic reaction. Mice in the blank group were smeared in the same way without allergenic reaction. The auricle swelling and the inhibition ratio were determined at 24 h after attack. Blood was collected from orbit and serum IgE level detected using double-antibody sandwich ELISA.
RESULTSCompared with the blank group, auricle swelling obviously increased and serum IgE level was obviously elevated in the model group (P < 0.01). Compared with the model group, auricle swelling obviously decreased and serum IgE level was obviously reduced in the 3 dose DY groups (P < 0.05, P < 0.01). Meanwhile, the auricle swelling degree was superior in high and middle dose DY groups to that in the loratadine group (P < 0.05). The inhibition ratio of auricle swelling was sequenced from high to low as 67.3% in the high dose DY group, 56.0% in the middle dose DY group, 48.1% in the low dose DY group, 47.3% in the loratadine group.
CONCLUSIONSDY could inhibit auricle swelling and lower serum IgE level. It also could inhibit delayed allergic reaction in model mice with QBDS to some extent.
