Objective To discuss Extracorporeal Membrane Oxygenation(ECMO) management method and effect during inter-hospital transport of potential cardiac death donors after cardiac death (DCD).Methods 8 potential donors after cardiac death with brain injury were supported by ECMO for inter-hospital transport.All donors were inserted Medtronic overall cannula into one side femoral artery and venous.The position of catheters were guided by ultrasound.The front-end of venous catheter located in the junction of atrium and inferior vena cava,meanwhile the front-end of artery catheter was below renal artery.100 IU/kg heparin was injected before inserting cannulas.Flow of ECMO maintained at 2.0～3.0 L/min,and oxygen flow was 2～3 L/min during ECMO supporting.When hemodynamics of potential donors were stable,patients were moved into ambulance with ECMO for inter-hospital transport.Results A total of 8 ECMO transports were performed for central circulatory collapse caused brain injury.Patients were previously cannulated and on ECMO prior to transport and transported a distance of more than 100 kilometer from our institution by ambulance.ECMO running times were 120 min,and operation process circulatory stable.Conclusion ECMO can ensure inter-hospital transport of potential donors after cardiac death safety.

Objective To investigate the role of c-Jun N-terminal kinase (JNK1/2) signaling pathway in enterovims 71 (EV71) infection.Methods The effects of different concentrations of SP600125 on the activity of human rhabdosarcoma (RD) cells were detected by trypanbalu staining.The levels of VP1 mRNA and protein in EV71-infected RD cells were detected by real time Q-PCR and western blot,respectively.The levels of total and phosphorylated JNK1/2,c-Fos and c-Jun protein were determined by western blot.Last,the effects of.JNK1/2 inhibitor SP600125 on EV71 replication and JNK1/2 signaling pathway were analyzed.Results The results of trypanbalu staining showed that 5 and 10 μmol/L of SP600125 didn't influence on the activity of RD cells (P ＞ 0.05),while 20 μmol/L of SP600125 decreased the survival of RD cells significantly (P ＜ 0.05).Compared with the control,the expression levels of VP1 mRNA and protein in EV71-infected RD cells decreased obviously at 8 hours post-infection (P ＜0.01).In addition,after RD cells were infected EV71,the levels of phosphorylated JNK1/2,c-Fos and c-Jun increased significantly (P ＜ 0.05).However,the pretreatment of SP600125 decreased the phosphorylation levels of JNK1/2,c-Fos and c-Jun protein obviously (P ＜ 0.05).Conclusion EV71 infection may effectively activate the JNK1/2 signaling pathway in RD cells,which may be related to EV71 replication.

Objective To investigate the expressions of acetylcholine and norepinephrine of the central nervous system in a rat model of irritable bowel syndrome (IBS), and to explore the possible roles of the classical neurotransmitters of the central nervous system in the pathogenesis of IBS. Methods The rat model of IBS was reproduced by intragastric instillation of 2.0ml water at 0-4℃ in male Wistar rats for two weeks. Both the model group and the control underwent rectal distention, then were sacrificed by deep anesthesia. Sections of the posterior horn of the spinal cord and hypothalamus were obtained and processed immunohistochemically using anti-tyrosine hydroxylase (TH) and acetylcholinesterase (AchE) antibodies respectively, and the staining results were analyzed semi-quantitatively using computerized color image analyzer. The statistical difference of the opacity density and immunoreactive areas between two groups was compared by t-test. Results Immunoreactive area, opacity density of AchE immunoreactive tissues in the posterior horn of the spinal cord and hypothalamus of the model group were all significantly higher than those in control group (P0.05). Conclusions The expressions of acetylcholine in the spinal cord and hypothalamus in the rat model of C-IBS were abnormal, which suggested that cholinergic nervous system in the central nervous system may play some roles in the pathogenesis of IBS.

Objectives To find out the effects of estrogen and clomiphene on behavior of epileptic rats induced by kainic acid (KA) and probe into some mechanisms. Methods Ovariectomized Sprague-Dawley female rats were treated with estrogen (E) or estrogen and clomiphene (C). Their behaviors when they were induced seizures were observed and compared. Indirect immunofluorescence method was used to measure the alterations of gamma-aminobutyric acid (GABA) immunoreactive cells and ?1 subunits of GABA_A receptors in the hippocampus of all groups. Results The latency and time at reaching 4/5 degrees in KA+E group ((24.63?11.44) minutes and (41.50?16.22) minutes, respectively) were reduced greatly than KA group ((46.75?14.61) minutes and (65.13?12.99) minutes), while the latency of (KA+)E+C group (adding estrogen and clomiphene, (43.50?5.75) minutes) became prolonged significantly than in KA+E group. Conclusion High-level estrogen should be proconvulsant and the clomiphene might have some antiepileptic effects, which may be related with some alterations of GABA energic function in the brain.

Objective To study protective effects of Wuzi Yanzong Fang on DNA damage induced by cyclophosphamide (CTX) in mice, and explore its mechanism. Methods BalB/c mice were randomly divided into normal group, model group, Wuzi Yanzong Fang low dose group and Wuzi Yanzong Fang high dose group. Mice in Wuzi Yanzong Fang groups were pretreated with Wuzi Yanzong Fang for 7 days, then the mice in Wuzi Yanzong Fang groups and model group were intraperitoneally injected with CTX (100 mg/kg) every other day for three times, and mice in Wuzi Yanzong Fang groups were continued administered with Wuzi Yanzong Fang. Animals were sacrificed in twelve hours after the final treatment of CTX. ELISA was used to detect 8-OHdG content in serum, and single cell gel electrophoresis to detect DNA damage in bone marrow cells. Results Wuzi Yanzong Fang low dose group and high dose group reduced the level of 8-OHdG in serum. Wuzi Yanzong Fang significantly decreased Olive tail moment, tail moment, tail length and tail DNA%in mouse bone marrow cells. Conclusion Wuzi Yanzong Fang has good protective effects on DNA damage caused by CTX.

ObjectiveTo assess negative risk factors associate with short-term and long-term poor outcome of acute heart failure syndromes(AHFS) and provide evidence to emergently proceed to AHFS low risk stratification.Methods A retrospective cohort study was conducted. 125 AHFS patients who met research criterion were enrolled from Guangxi Baise People's Hospital and Youjiang District People's Hospital of Baise City. The patients were divided into poor outcome and relatively low-risk groups by the results of short- and long-term follow-up of their outcomes. The patient's vital signs and disease history were collected at the first time after admission, and auxillary examination parameters were recorded. The poor outcomes occurring in the follow-up periods from the admission to after discharge for 30 days(short-term) and 1 year(long-term)were recorded, and Cox hazard regression was used to analyze the negative risk factor in the short- and long-term.Results There were 58 cases(46.4%)with poor outcome and 30 cases(24.0%)dead in short-term, and there were 111 cases(88.8%) with poor outcome and 39 cases(31.2%) dead in the long-term follow up. Seven negative risk factors were identified by Cox regression. They were no previous or de novo myocardial infarction〔short-term: hazard ratio(HR)=0.36, 95% confidence interval (95%CI)=0.20-0.65,P=0.001〕, lymphocyte ratio 0.20-0.40(short-term:HR=0.13, 95%CI=0.04-0.47, P=0.002; long-term:HR=0.42, 95%CI=0.26-0.68,P=0.001),oxygenation index(PaO2/FiO2)>300 mmHg (1 mmHg=0.133 kPa,short-term:HR=0.23, 95%CI=0.09-0.54,P=0.001),estimated glomerular filtration rate (eGFR)>60 mL·min-1·1.73 m-2(short-term:HR=0.31, 95%CI=0.16-0.64,P=0.002;long-term:HR=0.54, 95%CI=0.36-0.83,P=0.004),left ventricular ejection fraction(LVEF)>0.50(short-term:HR=0.29, 95%CI= 0.10-0.85,P=0.024), P wave terminal force in lead V1(PtfV1)>-0.04 mm·s(short-term:HR=0.29, 95%CI= 0.14-0.60,P=0.001), planar QRS-T angle<90°(long-term:HR=0.46, 95%CI=0.27-0.77,P=0.003). ConclusionsOur patients with AHFS cohort have very poor outcomes both in short-term and long-term follow up. Those with the following characteristics: no previous or de novo myocardial fraction, lymphocyte ratio 0.20-0.40, PaO2/FiO2>300 mmHg, eGFR>60 mL·min-1·1.73 m-2, PtfV1>-0.04 mm·s, LVEF>0.50 and planar QRS-T angle<90°are more likely to have optimal short-term and long-term outcome.

Background and purpose:Pain is one of the most common symptoms in advanced cancer patients, and morphine is a representative drug in controlling moderate to severe cancer-induced pain, but some unacceptable adverse effects limited its use in part of patients.We evaluated the effect and safety of morphine sulfate controlled-release tablet (MS-CRT) combined with celecoxib for the treatment of moderate to severe cancer pain, and assessed the life quality of patients. Methods:Retrospective analysis of 125 cancer patients with moderate to severe cancer pain who were divided into two groups, one(including 67 patients) was treated by single drug of MSCRT whose initial dosage was 20 mg/12 hrs, then evaluated by verbal rating scale within 24 to 48 hrs, dosage was adjusted personally according to the state of pain (increasing rate was 50% and declining rate was 25%) until the maintenance dosage was reached; the other(including 58 patients) was treated by MS-CRT with the same initial dosage and combined with celecoxib whose dosage was 200 mg/12 hrs at first, and increased to 400 mg/12 hrs if the pain was not relieved well, then gradually increased the dosage of MS-CRT to the maintenance dosage, and analyzed the effect, dose adjustment,side effect of drug combination and improvement of quality of life for the patients. Results:The mean of maintenance dosage for MS-CRT alone was 67.3 mg/day, and for the combination of MS-CRT and celecoxib was 51.3 mg/day, the reduction rate of MS-CRT in the drug combination group compared with MS-CRT alone was 23.77% with the same analgesia effect, and the incidence of side effects such as constipation and nausea/vomiting was statistically reduced compared with the single drug group. The quality of life in both groups was improved aftertreatment. Conclusion:The combination of MS-CRT and celecoxib can effectively control moderate to severe cancer pain, , improve the quality of life in advanced cancer patients, and reduce the consumption of MS-CRT with similar side effects as morphine alone.

The effects of high-intensity pulsed electromagnetic stimulation (HIPEMS) on proliferation and differentiation of neonatal rat neural stem cells in vitro were investigated. Neural stem cells derived from neonatal rats were exposed to 0.1 Hz, 0.5-10 Tesla (T) [8 groups of B-I, respectively], 5 stimuli of HIPEMF. The sham exposure controls were correspondingly established. Inverted phase contrast microscope was used to observe the cultured cells, MTT assay to detect the viability of the cells as expressed by absorbance (A) value, and flow cytometry to measure differentiation of neural stem cells. The results showed that A values of neural stem cells in both 3.0 T and 4.0 T groups were significantly higher than the other groups 24 to 168 h post HPEMS, indicating a strong promotion of the growth of neural stem cells (P<0.05). The A values of neural stem cells in the 6.0 T, 8.0 T, and 10.0 T groups were lower than the sham exposure control group, indicating a restraint of the growth of neural stem cells. The rate of neuron-specific enolase-positive neurons revealed by flow cytometry in HPEMS groups was the same as that in control group (P>0.05). It was suggested that 0.1 Hz, 5 pulses stimulation of HPEMS within certain scale of intensity (0.5-10.0 T), significantly promoted the growth of neural stem cells with the rational intensity being 4.0 T.

ObjectiveTo elucidate the association between aquaporins (AQPs) expression in kidney tissue and edema of nephrotic syndrome(NS) patients.MethodsNS patients were divided into edema group (14 cases) and non-edema group (8 cases).Ten patients without NS were used as control group.Expressions of AQP1,AQP2,and AQP4 in renal tissues of 3 groups were detectedbyimmunohistochemistrywithstandardtechniquesandsemi-quantitativeanalysis.Association between AQPs expression and edema was examined.ResultsThe positive index of AQP1 expression in proximal tubules in edema group was 0.0373±0.0110,which was significantly lower as compared to non-edema group (0.0510±0.0120) and control group 0.0574±0.0100),while the difference between non-edema and control groups was not significant.The positive index of AQP1 expression in glomerulus was 0.0106±0.0037 in edema group,which was significantly higher than that in non-edema group(0.0021±0.0013) and control group(0.0020±0.0012),while no significant difference was found between the last two groups.AQP2 mainly localized in the collecting duct system.The positive indexes of AQP2 expression were 0.0498±0.0081,0.0370± 0.0072 and 0.0255±0.0103 in edema group,non-edema group and control group,respectively.The differences were significant among 3 groups.AQP4 expression was not found in the renal cortex and collecting duct system.ConclusionsAQPs expression is different in renal tissues of NS patients.AQP2 may play an important role in the edema of NS patients,and AQP1 may involve in the occurrence of edema.

Objective To explore the personality change in patients with epilepsy during the interictal period and the correlation between clinical features and personality change. Methods One hundred and fifteen patients with idiopathic or cryptogenic epilepsy were chosen as the epileptic group and 42 age- and sex-matched healthy subjects served as controls. All participants were evaluated by Mini Mental Status Examination and Brief Psychiatric Rating Scale to ensure the normality of cognition and mental state.Personality was evaluated by adult version of Eysenck Personality Questionnaire (EPQ)in interictal epilepsy patients and healthy controls.Scores of psychoticism (P),extraversion (E),neuroticism (N) and lie (L)were obtained using computer software. Pearson correlation analysis and logistic regression were used to investigate the scores of EPQ and influential factors.Results P and N scores were significantly elevated in epilepsy patients compared with controls ( P scores:50.48 ± 9.55 vs 46.59 ± 7.28,N scores:51.13 ±12.89 vs 46.83 ± 9.40 ; t =2.374,2.266,both P ＜ 0.05 ),while E scores were significantly decreased (51.74 ± 10.74 vs 60.37 ± 9.84;t =- 4.511,P ＜ 0.01 ).There were no significant differences in L scores.Multivariate analysis showed that disease duration was independently correlated to P scores (β =0.043,P＜0.05),while education was correlated to E scores (β =0.109,P ＜ 0.05 ).There were no significant correlations between personality scores,patient age,gender,age of onset,frequency,seizure type,National Hospital Seizure Severity Scale scores,family history,history of status epilepticus and antiepileptic drugs usage.Conclusions High psychoticism and neuroticism and low cxtraversion scores are correlated to patients with epilepsy during the interictal period.Disease duration is an independent risk factor for psychoticism personality,and education level is an independent risk factor for extraversion personality in epilepsy patients.
