BACKGROUND:It has been reported that blast wave and haze can lead to hemodynamics disturbance.However,studies on blast-haze combined injury on hemodynamics changes are few.OBJECTIVE:To investigate the effect of blast-haze on the hemodynamics parameters during early period following cabin explosion,additionally,to evaluate the feasibility of brain natriuretic polypeptide(BNP) to serve as the damage criterion in early detection.DESIGN,TIME AND SETTING:Randomization,experimental observation of animal was performed at the Research Institute of Surgery,Daping Hospital,Third Military Medical University between August 2006 and August 2007.MATERIALS:One hundred and four healthy,male SD rats were randomly divided into the normal control(n=8),blast injury(n=48),and combined injury(n=48) groups.METHODS:The rats were fixed in the cabin according to the position of the war sitting,0.4 g cyclotrimethylene trinitramine were used to explosion in the centre of the cabin.The rats in the blast injury and combined injury group were took out immediately and 100 s after explosion,respectively.No treatment was performed in the normal control group.MAIN OUTCOME MEASURES:The heart function changes,the level of BNP,as well as the pathological change of lung tissues were analyzed by ELISA,double antibody sandwich method,and the microscope at 1,3,6,12,24,and 72 hours after injury,respectively.RESULTS:Compared with the normal control group,there were significantly differences of pathomorphological changes in the blast injury and combined injury groups,even,more severe in the combined group than the blast injury group.The level of BNP at each time point was higher than that of the normal control group(P

Objective To examine the impact of cognitive behavior intervention (CBI) on mother-infant interaction in the neonatal department. Methods Low-risk appropriate for gestational age premature infants with gestational age 28-36 weeks, who were admitted to the neonatal intensive care unit in our hospital between August 2007 and May 2008, and their mothers were assigned to intervention group and control group respectively. Intervention group mothers (n = 19)participated in CBI. Control group mothers (n= 19) were asked to read educational materials. Mothers in the intervention group, all received 4 times interventions and 2 h for each time. The CBI process include assessment, plan, implementation and evaluation. Mothers were educated for knowledge about appearance and behavioral characteristics of preterm infants and were guided about how to take care of their babies and participate in nursing care process. Mothers completed measures on mother-infant interaction (Nursing Child Assessment Feeding Scale, NCAFS) in the first follow-up after infant discharge. Results The results showed that the scores of NCAFS and total scores of the mothers in the intervention mother-infant dyads were 46.4 ± 8.5 and 35.8±6.3,higher than in the control group (42.7±5.9 and 33.3 ± 5.6), respectively, but there were no statistic difference between the two groups (t = 1.55 and 1.28, P＞ 0. 05). The scores of "mother's response to distress" were significantly higher in the intervention mother-infant group (12. 2± 1.7) than in the control group (10.7±2.4)(t=2.10,P＜0.05). Conclusions The levels of premature infant-mother interactions are low. CBI can improve mother's response to premature infant's distress. Further study is needed to investigate the effects of CBI in improving mother-infant interaction.

ObjectiveTo investigate the effects of care bundles on the lactation of mothers of preterm infants.MethodsFrom January to June 2015, postpartum women who had preterm deliveries in First Maternity and Infant Hospital Affiliated to Tongji University with the neonates hospitalized in neonatal intensive care unit were enrolled in this study. They were randomly divided into intervention group (n=25) receiving bundle care (assist the mothers to determine lactation target; pump/express breastmilk within six hours after birth and keep a lactation diary to record the times and volume of pumped/expressed milk) and control group (n=22) given normal mammary guidance only. The time of the first pumped/expressed milk, the times for pumping/expressing milk a day, the total milk volume per day and rate of breastfeeding were compared between the two groups. Statistical analyses were conducted using two independent samplest-test,Chi-square test and nonparametric test.ResultsThe initial time of pumped/expressed milk of the intervention group was (6.1±3.4) h after delivery, significantly earlier than the control group [(10.7±9.3) h](t=-2.301,P=0.026). The times for pumping/expressing milk per day were significantly more in the intervention group than in the controlgroup on the 1st, 2nd and 3rd day after delivery [(4.2±2.2) vs (3.0±1.6); (6.2±1.1) vs (4.7±1.9); and (7.1±1.9) vs (5.9±1.9) times, respectively](t=2.083, 2.564 and 2.194, allP<0.05). From the second postpartum day, the milk volume of the intervention group was more than the control group [M(range) were 10.0(25.0) vs 2.0(5.0) ml] (Z=-2.879,P=0.005); and on the 21st day, the milk volume of the intervention mothers reached 800.0(295.0) ml, still higher than the control group [300.0(155.0) ml](Z=-3.179,P=0.001). The primarily breastfeeding (adding formula milk≤2 times a day) rate in the intervention group was significantly higher than in the control group on the 42nd postpartum day [68% (17/25) vs 41% (9/22),χ2=5.874,P=0.045].ConclusionThe care bundles on lactation can improve the lactation of the mothers of preterm infants.

Objective To explore the relationship between expected drop and postpartum depression,analysis of influence factors of postpartum depression.Methods Chinese version of Postpartum Support Questionnaire and Edinburgh Postnatal Depression Scale were used to investigate 411 puerpera of 42-56 days postpartum by the convenience sampling method.Results The incidence rate of postpartum depression was 17.03％ (70/411).The correlation coefficient r between the actual situation of postpartum social support and the score of each dimension and the score of Edinburgh Postpartum Depression Scale was 0.157 to 0.247 (P ＜ 0.01).The correlation coefficient r between the postpartum social support expectation drop and the Edinburgh Postpartum Depression Scale score was 0.173 to 0.230 (P ＜ 0.01).Regression analysis showed postpartum depression was related to emotional support,nursing mode,registered permanent residence and gender expectations for baby.Conclusions The positive rate of postpartum depression is still higher.How to reduce the incidence of postpartum depression is still a problem to be solved.According to the characteristics of social support and maternal postpartum to evaluate the importance of targeted social support can reduce the incidence of postpartum depression.

BACKGROUND: The activation of hypothalamus-pituitary-adrenal cortex axis may play key role in the increasing expression of hypothalamic corticotropin-re-leasing hormone (CRH) during stress reaction. However by what way to induce the CRH expression in hypothalamic neuron, and whether CRH can activate hypothalamic neurons are still not very clear.OBJECTIVE: To observe the changes of intracellular cyclic adenosine monophosphate (cAMP) and cytoplasmic Ca2+ concentration in the hypothalamic neurons cultured in vitro due to exogenous CRH stimulation.DESIGN: Comparative observation experiment.SETTING: Research Institute of Surgery, Daping Hospital, Third Military Medical University of Chinese PLA; Department of Neurosurgery , Tiantan Hospital, Capital University of Medical Sciences MATERIALS: This experiment was carried out in the Research Institute of Surgery, Daping Hospital, Third Military Medical University of Chinese PLA between December 1999 and March 2002. Hypothalamus was obtained from fetus rat at pregnancy of 17 days for the in vitro culture of hypothalamic neurons.METHODS: Hypothalamic neurons were co-cultured with exogenous CRH,with or without pretreatment with specific CRH 1 receptor antagonist -CP-154526. hypothalamic neurons were randomized into: ① CRH (10-12,10-10, 10-8, 10-6 mol/L) stimulation group. ② CP-154526(500 μmol/L)pretreatment aud CRH ( 10-12, 10-10, 10-8,10-6 mol/L) stimulation group. ③Hypothalamic neurons in corresponding normal control group were exposed to the isotonic saline stimulation. PTI fluorescence image system was used to determine and analyze the change of cytoplasmic free Ca2+ concentration in hypothalamic neurons due to exogenous CRH stimulation and RIA was used to detect the neuronal cAMP content.MAIN OUTCOME MEASURES: ①Cytoplasmic free Ca2+ concentration in hypothalamic neurons. ②cAMP content in hypothalamic neurons.RESULTS: The cytoplasmic free Ca2+ concentration and cAMP content were relatively lower in the hypothalamic neurons in normal control group,which obviously increased due to CRH stimulation [(240±22),(153±11)nmol/L; (3.26±0.19),(0.44±0.02) pmol/dish,P ＜ 0.01];CP-154526 could remarkably suppress the CRH (10-6 mol/L)induced increase in cytoplasmic free Ca2+ concentration and cAMP content in hypothalamic neurons [Ca2+ concentration: (240±22),(171±16)nmol/L; cAMP content:(3.26±0.19), (2.33±0.21) pmol/dish, P ＜ 0.01].CONCLUSION: CRH can directly act on hypothalamic neurons via type 1-receptor,thereby increase the cytoplasmic free Ca2+ concentration and cAMP content in hypothalamic neurons,playing the key role in the modulation of the synthesis and secretion of CRH during the activation of hypothalamic neurons.

BACKGROUND: Through what signal pathway does corticotropin release hormone (CRH) regulate hypothalamic neuronal neuroendocrine activity during acute stress?OBJECTIVE: To probe into the regulatory effects of CRH on CREB secretion in hypothalamic neurons.DESIGN: Repetitive measurement design.SETTING: At Field Surgery Research Institute of Daping Hospital, Third Military Medical University of Chinese PLA; Neurosurgery Department,Tiantan Hospital Affiliated to the Capital University of Medical Sciences.MATERIALS: This experiment was carried out in Daping Hospital of Third Military Medical University of Chinese PLA between December 1999and March 2002. Rat fetuses were selected from Wister rats of 17-day gestation.METHODS: In vitro cultured cells were divided into the following groups:① CRH (10-12, 10-10, 10-8 and 10-6 mol/L) stimulation groups. ② Pretreated with nimodipine (5 μmol/L) or CP-154526 (500 μmol/L) followed by CRH (10-12, 10-10, 10-8 and 10-6 mol/L ) stimulation groups. ③ Corresponding control groups stimulated with isotonic physiological saline. PTI fluorescence imaging system was used to detect the changes of neuronal cytoplasmic free calcium concentration; meanwhile, Western blot technique was used to determine the changes of neuronal P-CREB content.MAIN OUTCOME MEASURES: ① Changes of neuronal cytoplasmic free calcium concentration. ② Changes of neuronal P-CREB content.RESULTS: The content of cytoplasmic free calcium in hypothalamic neurons was lower in normal control group, and it increased immediately after exogenous CRH stimulation. However, such increase could be suppressed by pretreatment with nimodipine or CP-154526 before CRH stimulation,and the increase of neuronal P-CREB content was also obviously suppressed.CONCLUSION: During acute stress, the combination of CRH with hypothalamic neuronal CRH 1 receptor leads to the opening of membrane Ltype calcium ions channels, thus enhancing the influx of calcium ions and increasing cytoplasmic free calcium ions content, which would further activate P-CREB signal transduction pathway in neurons. It suggests that CRH may play a vital role in hypothalamic neuronal activation.

Objective To discuss the clinical correlation between chronic prostatitis (CP) and erectile dysfunction (ED).Methods A retrospective analysis was made on the clinical data from patients who were diagnosed as CP in urology department of the First People's Hospital of Yunnan Province and the First Affiliated Hospital of Sun Yat-sen University.Patients' data were collected from July 2005 to July 2012.All the patients were diagnosed as CP based on their clinical manifestation,the NIH Chronic Prostatitis Symptom Index,prostatic fluid examination,routine urine examination and ultrasonography.The condition of erectile function was inquired on every patient and recorded.Results There were 4 315 patients diagnosed as CP in present study,while their age ranged from 17 to 64 years (average,31 years).Sixty-one (1.41％) patients were identified as moderate and severe types of ED (International Index of Erectile Function 5 ≤ 11),while 42 (0.97％) patients were confirmed as ED after they got CP.435/4 315 patients (10.08％)felt obviously sexuality descent after they got CP,and the sexuality was reported improved in 426/435 pa-tients after prostatitis symptomatic relief.Conclusions The incidence rate of ED in CP patients is not ob-viously higher than that in common community.And sexuality descent in patients might be caused by localindisposition and anxiety after CP.

Objective To explore the role of glucose-regulated protein 78 (GRP78),p38 mitogen-activated protein kinase(p38MAPK) signal pathway in seizure-reduced brain injures and the regulatory effect of Nimodipine on it.Methods Sprague-Dawley(SD) rats were randomly divided into status convulsion group (SC group),Nimodipine group(NM group),and a normal control group(NC group).The expressions of GRP78/Bip and p38MAPK mRNA and protein were detected by reverse transcription(RT)-PCR and immunohistochemistry.The expression of apoptosis cells was observed by TdT-mediated dUTP nick end labeling (TUNEL).Results (1) Immunohistochemistry:at 4 h after induction of status convulsion,the expression of GRP78 protein in the hippocampus CA1 domain began increasing slightly,and reached a maximum at 24 h,and then began decreasing slowly ; at 4 h after induction of status convulsion,the expression of p38MAPK protein in the hippocampus CA1 domain began increasing,and reached a maximum at 24 h,and decreased remarkably at 48 h.(2) RT-PCR:at 4 h after induction of status convulsion,the expression of GRP78 protein in the hippocampus CA1 domain began increasing slightly,and reached a maximum at 24 h,and then began decreasing slowly.The NM group was much higher than the SC group and the NC group(all P ＜ 0.05) ; at 4 h after induction of status convulsion,the expression of p38MAPK protein in the hippocampus CA1 domain began increasing,and reached a maximum at 24 h,and decreased remarkably at 48 h;the NM group was much lower than the SC group,and higher than the NC group (all P ＜ 0.05).(3) TUNEL:at 4 h after induction of status convulsion,the expression of the TUNEL positive cells in the hippocampus CA1 domain began increasing slightly,and reached a maximum at 48 h,and then began decreasing,and there was no difference between SC group and NC group;the NM group was much lower than the SC group(all P ＜ 0.05).Conclusions The correlation of the increased expression of p38MAPK and neuronal apoptosis indicates that GRP78 signal pathway may be mediated to cell apoptosis through p38MAPK.Nimodipine can affect the expression of GRP78/Bip and p38MAPK,and relieve endoplasmic reticulum stress,and lessen the pathologic damage to the hippocampus.

Objective: To provide an important tool for the study of diagnose and treatment of prostate cancer (PCa) osseous metastasis and change of bone stress force on prostate cancer (PCa) osseous metastasis and a platform, which is more congruous to clinical process, for prevention and cure of neoplastic bone metastases, and to carry out the construction and improvement of animal models of PCa with different positional osseous metastasis in vivo.Methods: Different gradient concentrations of RM-1 cells were inoculated into the cavity of left femoral bone or lumbar vertebra of mice (C57BL/6) respectively.The change of mouse activity, tumor formation, tumor size and survival time were observed respectively.And the femur tissue and spinal tissue were obtained from the mice after death.The gray value of iconography were measured by imageological examination of femur tissue, and the final histopathological examination were taken to determine the tumor type in both femur and spinal tissue.Results: The tumor growth could be touched at the puncture site in all the mice after inoculated for 7 days.There were no obvious differences in the time of tumorigenesis, the rate of tumor growth and tumor size among the mice in the same group (P>0.05).As the result, the construction femoral bone and lumbar vertebra metastatic models of PCa had been confirmed by iconography and pathology detection.At the same time, the survival time of the mice inoculated with low concentrations of PCa cells was obviously longer than that of high concentrations of PCa cells (at least 2 weeks longer).Conclusion: The animal models with different positional osseous metastasis (limbs and axial skeleton) of PCa using the same PCa cells (RM-1) had been first constructed successfully in our study.At the same time, a high success rate of construction of PCa animal model with bone metastasis was obtained by femoral bone marrow cavity injection of PCa cells.The rate of tumor growth was rapid, animal survival time was appropriate, and the PCa animal model with bone metastasis can be stably reproduced by our method.These animal models can be used to explore the pathogenesis of different positional PCa bone metastasis and provide a new platform, which were more congruous to clinical process, for prevention and cure of neoplastic bone metastases.
