Conclusion The QQ group follow up of nursing education can reduce the incidence of adverse reactions by radiotherapy after discharge.

Objective To investigate the effectiveness of botulinum toxin A (BTX-A) injection to the external urethral sphincter guided by ultrasound in the treatment of various types of lower urinary tract dysfunction.Methods Twenty-two patients with urinary retention caused by neurological dysfunction (neurogenic bladder) were recruited,of which 18 were men and 4 women.They had various types of lower urinary tract dysfunction including detrusor external sphincter dyssynergia (DESD) in 7,nonrelaxing urethral sphincters in 5,and detrusor underactivity in 10.BTX-A (100 U) was injected into the external urethral sphincter at three different points guided by ultrasound.Clinical effects and urodynamic parameters were compared at baseline and after treatment.Results After treatment the urinary function and urodynamic parameters in each group improved significantly compared with the baseline.Maximum efficacy was observed at the 4th week.In the DESD group,3 patients (43％) had an excellent result and 3 (43％) had significant improvement; in the nonrelaxing sphincter group 3 (60％) had excellent results and 2 (40％) showed significant improvement; in the detrusor underactivity group 5 (50％) had excellent results and 3 (30％) had significant improvement.There were no obvious side effects.Conclusions BTX-A injections guided by ultrasound can accurately locate the external urethral sphincter.It is a simple and repeatable method for the treatment of lower urinary tract dysfunction.

Objective To explore the clinical value of high-frequency color Doppler ultrasound in the diagnosis of isolated calf muscle vein thrombosis (ICMVT). Methods Sonographic features of 175 patients with isolated calf muscular venous thrombosis were analyzed retrospectively and outcome of anticoagulant therapy in 1, 3, and 6 months was followed up. Diagnosis was established with high-frequency color Doppler ultrasound examination. Results One hundred and seventy-ifve patients presenting with 190 calf muscle vein thrombosis were included. One hundred and iffty-eight cases with 173 calf muscle vein thrombosis were diagnosed by high-frequency color Doppler ultrasound, 7 cases of misdiagnosis, missed diagnosis in 10 cases. The accuracy rate was 91.1%(173/190). Seven cases were misdiagnosed with 1 euroifbromatosis, 1 mixed hemangioma, 5 gastrocnemius hematoma. After diagnosis of ICMVT, all patients prescribed thrombolysis and anticoagulation therapy. High-frequency color Doppler ultrasound for 1, 3, 6 months after treatments revealed partial or complete recanalization without calf deep vein thrombosis. Typical sonographic features included:calf muscle venous lumen dilation, tortuous anechoic lumen or hypoechoic iflling, with tubular or branched shape in the longitudinal view and oval or round shape in the transversal view. Conclusion High-frequency color Doppler ultrasound is an accurate and reliable method in the diagnosis of the isolated calf muscular venous thrombosis.

Objective To investigate anti-hypertension threapy on seasonal variability of blood pressure,urinary 8-OHdG levels in essential hypertension in order to provide a basis for seasonal antihypertensive treatment.Methods Fifty hypertensive patients admitted the hospital of Erdos Clinical Medical College of Inner Mongolia Medical University at summer 2013 were selected as our subjects.The final subjects was 42 cases due to 8 lost cases.The patients were randomly divided into two groups,including 30 cases in renin angiotensin aldosterone system inhibitors(RASI) group and 12 cases in Ca2+ channel blocker(CCB) group.Epidata 3.1 software was applied to perform statistic analysis.Urinary 8-OHdG concentration was measured by enzyme-linked immunosorbent assay (ELISA).Blood pressure was measured in spring,summer,autumn and winter.Results Systolic blood pressure(SBP) in RASI group and CCB group at winter periods were (158±20) mmHg,(158 ± 20) mmHg,higher than that in summer periods ((145 ± 12) mmHg,(141 ± 9) mmHg;P＜ 0.05).Diastolic blood pressure(DPB) in RASI group and CCB group at winter periods were (101 ± 13)mmHg and (100±4)mmHg,significant high than that in summer periods ((93 ±7) mmHg,(90±7) mmHg;P＜0.05).8-OhdG levels in RASI group at summer and autumn periods were (243.20±30.94) ng/L and (240.40±47.99) ng/L,significantly higher than that in winter and spring periods((190.80± 15.56) ng/L and (189.06± 13.56) ng/L),and the differences were significant(P＜0.001).No significant differences were seen in CCB group among 4 seasons in terms of 8-OhdG levels (P ＞ 0.05).Conclusion Blood pressure change still occur among 4 seasons in hypertensive patients after a single CCB containing RASI-based drug antihypertensive therapy.And blood pressure in winter periods is higher than that in summer,which indicates that therapy medication based on RASI might reduce the level of oxidative stress at winter periods.

This study was to investigate the effects of the combination of deoxynivalenol (DON) and zearalenone (ZON) on pigs. Twenty-four weaning piglets were divided into a control group fed a diet free of mycotoxins and a toxin group fed a diet containing 1 mg/kg DON and 250 microgram/kg ZON. The results showed that supplementation of DON and ZON in diets had extensive effects on pigs. More specifically, DON and ZON caused levels of total protein, albumin, and globulin in sera to decrease (p < 0.05) by 14.5%, 6.5% and 11.3%, respectively, and at the same time increased (p < 0.05) the serum enzyme activities of gamma-glutamyltransferase, aspartate aminotransferase and alanine aminotransferase by 72.0%, 32.6% and 36.6%, respectively. In addition, DON and ZON decreased (p < 0.05) the level of anticlassical swine fever antibody titers by 14.8%. Real-time PCR showed that DON and ZON caused the mRNA expression levels of IFN-gamma, TNF-alpha, IL-2, to decrease (p < 0.05) by 36.0%, 29.0% and 35.4%, respectively. Histopathological studies demonstrated that DON and ZON caused abnormalities in the liver, spleen, lymph nodes, uterus, and kidney. The concentrations of DON and ZON used in this study are in line with the published critical values permitted by BML. Our study clearly put the standard and adequacy of safety measures for these toxins into question. The authors suggest that with the increasing availability of cellular and molecular technologies, it is time to revisit the safety standards for toxins in feeds so as to make feeds safer, providing consumers with safer products.

OBJECTIVE: To investigate the protective effect of a non-specific NMDA receptor antagonist memantine on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. METHODS: Healthy male mice were divided into 4 groups: a normal group, a memantine group, an ALI group and a memantine+ALI group. The ALI group was induced by intraperitoneal injection of LPS (10 mg/kg). Memantine (10 mg/kg) was injected intraperitoneally before the injection of LPS to determine the effect of blockade of NMDA receptor in the memantine+ALI group. The lung wet/dry ratio was detected. HE staining was preformed to show the morphological changes in the lung tissue. Myeloperoxidase enzyme (MPO) activity and malondialdehyde (MDA) content in the lung tissue were detected. ELISA was used to detect the tumor necrosis factor-α (TNF-α) content and lactate dehydrogenase (LDH) activity in the bronchoalveolar lavage fluid (BALF). RESULTS: Memantine pretreatment improved the LPS-induced ALI lung tissue morphological changes, reduced their lung wet/dry ratio, the levels of TNF-α and LDH activity in BALF, and also reduced the MPO and MDA content in the lung tissue. CONCLUSION Blockade of NMDA receptors can ameliorate LPS-induced mice ALI.

Objective:To observe any effect of repeated magnetic stimulation of the spine on lower urinary tract function and the life quality of patients with neurogenic bladder after suprasacral spinal cord injury (SCI).Methods:Fifteen suprasacral SCI patients whose lower urinary tract function was not improving were enrolled. In the first 2 weeks, all received water drinking management and intermittent catheterization, while in the following 4 weeks they were additionally provided with daily transspinal magnetic stimulation at the level of the spinous process of the first lumbar vertebra five times a week. The stimulation frequency was 1Hz. The patients kept voiding diaries. Their urodynamics were quantified using neurogenic bladder symptom scoring (NBSS) and a life quality scale.Results:The frequency of catheterization and the average voided volume, as well as the maximum detrusor pressure during the storage phase, maximum bladder capacity, maximum urethral pressure during the voiding phase and voiding efficiency at the end of the sixth week were significantly different from those at the end of the second week and before the intervention. The average NBSS and life quality scores then showed significant differences from the earlier time points.Conclusion:Repeteitive transspinal magnetic stimulation of the spine can improve lower urinary tract functioning and the life quality of persons with neurogenic bladder after a suprasacral SCI.

Objective To evaluate the cognitive dysfunction and its influential factors in patients with symptomatic and asymptomatic lacunar infarction(LI). Methods Mini-mental state examination (MMSE), MoCA and P300 were carried out among 70 patients with first attack of LI 1 week after, 66 patients with asymptomatic LI and 54 patients for control at first visit. The tests were performed again in the follow-up of half a year and one year. Results (l)The scores of MMSE and MoCA at 1 week, half a year and one year of LI at acute stage were lower than asymptomatic LI(P＜0. 01) and control group(P＜0. 01). Latent periods of P300 at each time point were longer than those in patients with asymptomatic LI (P＜0. 05) and control group (P＜0. 01). (2)The scores of MMSE and MoCA at first visit, half a year of follow-up and one year of follow-up in patients with asymptomatic LI were lower than those in control group(P＜0. 01), and the latent period of P300 was longer than that in control group(P＜0. 01). (3)The scores of MMSE and MoCA at 1 week of LI at acute stage and first visit of asymptomatic LI were higher than those after one year(P＜0. 05). The latent periods of P300 were shorter than those after one year(P＜0. 05). Compared with those half a year after, MMSE and MoCA one year after decreased more and the latent period of P300 prolonged(P＞0. 05). (4) The scores of MoCA in the aspects of visuospatial and executive function, abstract thinking and attention were lower than those in control group (P＜0. 01). (5)The score of MoCA in LI patients with multiple foci was lower than that in LI patients with single focus(P＜0. 01). The scores of MoCA in patients with foci in basal ganglia, frontal lobe, temporal lobe and thalamus were lower than those in patients with foci in other parts (P＜0. 01). Conclusion LI (both symptomatic and asymptomatic) is easily accompanied with cognitive dysfunction. The cognitive damage becomes more severe as time prolongs. The common symptoms include damages of visuospatial and executive function, abstract thinking and attention. Patients with multiple foci and with LI in key parts easily suffer from cognitive dysfunction. Thus, it needs to evaluate and prevent early.

OBJECTIVE: To investigate the efficacy of brain-targeted rapamycin (T-Rap) in treatment of epilepsy in rats. METHODS: Rapamycin nanoparticles targeting brain were prepared. The epilepsy model was induced by injection of pilocarpine in rats. The rats with pilocarpine-induced epilepsy were treated with rapamycin (Rap group) or brain-targeted rapamycin (T-Rap group). Seizure activity was observed by electroencephalography; the effect on mTOR signaling pathway was detected by Western blot; neuronal death and moss fiber sprouting were analyzed by Fluoro-Jade B (FJB) and Timm's staining, respectively. RESULTS: Electroencephalography showed that both preparation of rapamycin significantly reduced the frequency of spontaneous seizures in rats, and the effect of T-Rap was stronger than that of conventional rapamycin (<0.05). Western blot showed that the phosphorylation levels of S6K and S6 in T-Rap group were lower than those in Rap group (all <0.05), indicating that T-Rap had a stronger inhibitory effect on mTOR signaling pathway. FJB staining showed that T-Rap significantly decreased neuronal death, but there was no significant difference as compared with Rap group. Timm's staining showed that both preparations of rapamycin significantly reduced the germination of mossy fibers, while the effect of T-Rap was more pronounced than Rap group (<0.05). The inhibition of body weight gain of T-Rap group was less than that of Rap group (<0.05). CONCLUSIONS T-Rap has a better therapeutic effect on epilepsy than conventional rapamycin with a less adverse effects in rats.

Accumulating data have revealed that abnormal activity of the mTOR (mammalian target of rapamycin) pathway plays an important role in epileptogenesis triggered by various factors. We previously reported that pretreatment with perifosine, an inhibitor of Akt (also called protein kinase B), abolishes the rapamycin-induced paradoxical increase of S6 phosphorylation in a rat model induced by kainic acid (KA). Since Akt is an upstream target in the mTOR signaling pathway, we set out to determine whether perifosine has a preventive effect on epileptogenesis. Here, we explored the effect of perifosine on the model of temporal epilepsy induced by KA in rats and found that pretreatment with perifosine had no effect on the severity or duration of the KA-induced status epilepticus. However, perifosine almost completely inhibited the activation of p-Akt and p-S6 both acutely and chronically following the KA-induced status epilepticus. Perifosine pretreatment suppressed the KA-induced neuronal death and mossy fiber sprouting. The frequency of spontaneous seizures was markedly decreased in rats pretreated with perifosine. Accordingly, rats pretreated with perifosine showed mild impairment in cognitive functions. Collectively, this study provides novel evidence in a KA seizure model that perifosine may be a potential drug for use in anti-epileptogenic therapy.
