Objective\ To investigate the cardiovascular distribution of orphanin FQ (OFQ) and OFQ precursor mRNA in spontaneously hypertensive rat(SHR) and rabbit. Methods\ Reverse transcription polymerase chain reacrtion(RT PCR), and immunohistochemical method were used. Results\ The expression of OFQ precursor mRNA was detected from aorta, pulmonary artery, renal artery and vein of rat at a high level comparable with the amounts of brain, and a weak expression signal could also be observed in the atrium. The positive immunoreactive OFQ was detected in the tissues of aorta, atrium and renal of rabbit, as well as in smooth cells, endothelium and glomerulus. Conclusion\ These observations suggest that orphanin FQ might play a role in regulating the function of cardiovascular system and kidney, but the exact underlying mechanism needs further studying.

Obstructive sleep apnea hypopnea syndrome (OSAHS) is characterized by repeated episodes of upper airway obstruction that results in brief periods of breathing cessation (apnea) or a marked reduction in airflow (hypopnea) during sleep. Asthma is a chronic inflammatory disease of the airways characterized by revesible air-flow obstruction and bronchial hyperresponsiveness. This article reviewed related reseaches progress of relationship between the obstructive sleep apnea hypopnea syndrom and asthma in the vascular endothelial growth factor, systemic inflammation, leptin, obesity, gastroesophageal reflux disease and upper airway diseases, excessive daytime sleepiness and asthma control.

The primary etiopathology of pediatric OSAHS includes tonsil or adenoid hypertrophy. Severe OSAHS contributes to or aggravates thoracic deformity, which is rarely reported. In the current report, This children sleep snoring more than 4 years, increasing with thoracic severe depression during sleep 2 days. Clinical examination indicated tonsil and adenoid hypertrophy, and polysomnography revealed OSAHS . The symptoms of OSAHS and severe inhalation-related sternum depression disappeared rapidly after tonsillectomy. Our findings indicated that OSAHS were the major causes underlying funnel chest in children. The rarity of the incidence may result in missed diagnosis or misdiagnosis. Polysomnography was recommended for the child diagnosed with funnel chest accompanied by upper airway stenosis.

Objective: To investigate the effects of Wuling Capsule, a compound traditional Chinese herbal medicine, on hippocampal neurogenesis by examining the expressions of brain-derived neurotrophic factor (BDNF) and connexin 43 (Cx43) in rats with depression induced by chronic unpredictable mild stress (CMS), and thereby to explore its antidepressant mechanism. Methods: Forty-five adult male Sprague-Dawley rats were randomly divided into three groups: control group (n=15), untreated group (n=15) and Wuling group (n=15). All rats except those in the control group were subjected to 3-week CMS to induce depression. At the same time Wuling Capsule was daily added to the diet of the rats in the Wuling group at a dose of 100 mg/kg body weight for 21 days. The degree of depression was determined by sucrose preference test. BDNF expression and neurogenesis were tested by using immunohistochemical staining with BDNF and 5-bromodeoxyuridine (BrdU) antibodies; and the mRNA and protein expression levels of Cx43 in hippocampus were examined by semi-quantitative reverse transcription-polymerase chain reaction and Western blotting. Results: The numbers of BDNF-positive neurons and BrdU-positive particles in dentate gyrus (DG) were significantly decreased in CMS rats as compared with the normal rats, and the same changes were found in Cx43 mRNA and protein expressions. After Wuling Capsule treatment, the depressed behaviors were improved. Moreover, the reduced expression levels of Cx43 mRNA and protein and fewer newborn neurons induced by CMS were recovered to the normal levels. However, BDNF-positive cells remained low in DG. Conclusion: Wuling Capsule can improve the low hippocampal neurogenesis in rats subjected to CMS and the antidepressant effects are related to enhancing the Cx43 expression but not through BDNF mediation.

Objective To evaluate the effect of umbilical cord mesenchymal stem cell (UC-MSC) transplantation on cognitive function in endotoxemic rats.Methods Seventy-two pathogen-free male Wistar rats,aged 180-250 g,were randomly divided into 4 groups (n=18 each) using a random number table:control group (group C),endotoxemia group (group E),UC-MSC group (group M),and endotoxemia+ MSC group (group PM).Cognitive function was assessed using Morris water maze test.At 4 h before training on 2nd day of place navigation test,lipopolysaccharide 100 μg/kg was injected intraperitoneally in group E,the equal volume of normal saline was given in group C,UC-MSC suspension 300 μl (5× 105cells,the fluid was normal saline) was injected via the tail vein immediately after intraperitoneal lipopolysaccharide in group PM,and UC-MSCs were injected via the tail vein in group M.At 4 h after injection,Morris water maze test was continued.At 4,24 h and 5 days after intraperitoneal injection or injection via the tail vein (T1-3),6 rats were selected,and blood samples were collected from hearts.The rats were then sacrificed,and the hippocampus was removed.The levels of interleukin-lbeta (IL-1β),IL-6 and tumor necrosis factor-alpha (TNF-α) in serum and hippocampus were determined.Results Compared with group C,the escape latency was significantly prolonged on 2nd and 3rd days of Morris water maze test,the number of crossing the platform was significantly decreased,the percentage of swimming distance in 1 st quadrant in the total swimming distance was significantly decreased,and the levels of IL-1 β,IL-6 and TNF-α in serum and hippocampus were significantly increased at T1,2 in group E (P＜0.05).Compared with group E,the escape latency was significantly shortened on 2nd and 3rd days of Morris water maze test,the number of crossing the platform was significantly increased,the percentage of swimming distance in 1st quadrant in the total swimming distance was significantly increased,and the levels of IL-1β,IL-6 and TNF-α in serum and hippocampus were significantly decreased at T1,2 in group PM (P＜0.05).Conclusion UC-MSC transplantation can improve the cognitive decline in endotoxemic rats.

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.
