Objective To investigate the protective effects of morphine preconditioning on the lungs against ischemia-reperfusion (I/R) injury and the possible mechanisms.Methods Twenty-four Japanese long-ear white rabbits weighting 2.5-3.0 kg were used in this study. The animals were anesthetized with intramuscular atropine 0.5 mg and intravenous 3 % pentobarbital 30 mg ?kg-1, tracheostomized and mechanically ventilated ( VT 10 ml?kg-1, RR 30 bpm, FiO2 100% , PEEP 1 cm H2O) . Right carotid artery was cannulated for BP monitoring and blood sampling. An elastic band was placed around the hilum of left lung via thoracotomy to perform lung ischemia. Body temperature was maintained at 36-38℃( rectal) . The animals were randomly allocated to one of 3 groups (n = 8 each) : (1) Sham group; (2) I/R group was subjected to 2 h in situ left hilar occlusion followed by 2 h reperfusion and (3) morphine preconditioning group received morphine 4 mg?kg-1 via pulmonary artery 30 min before I/R. Mean pulmonary artery pressure (MPAP) and peak inspiratory pressure (PIP) were monitored and recorded. Arterial blood samples were taken before occlusion of lung hilum (baseline) and at 5, 30, 60, 90 and 120 min of reperfusion for blood gas analysis, and determination of plasma endothelin-1 concentration. The animals were killed at the end of 120 min reperfusion. The lungs were removed for determination of lung water content (W/ D ratio), percentage of neutrophils in the broncho-alveolar lavage fluid ( BALF) and microscopic examination.Results MPAP and PIP were significantly lower while PaO2 was significantly higher at 30, 60, 90 and 120 min of reperfusion in morphine preconditioning group than in I/R group. Plasma endothelin-1 concentration was significantly lower at 60 and 120 min of reperfusion in morphine preconditioning group than in I/R group ( P

Objective To explore the role of mouse dermis-derived mesenchymal stem cells (mdMSC) on skin repair. Methods mdMSC and human dermal fibroblasts were isolated and identified. Human dermal fibroblasts were cultured alone or eoeultured with mdMSC in Transwell chambers with the density ratio of human dermal fibroblasts to mdMSC being 2/5, 1/1, and 2/1. On day 4 and 8 of culture, the expression levels of hydroxyproline and transforming growth factor-beta (TGF-beta) 1 were measured in the supematant of monoculture and coculture by alkaline hydrolysis and ELISA respectively. Results The level of hydro-xyproline was significantly higher in the supematants of coculture system with a density ratio of 2/5 and 1/1 than that in monoculture supematants of human dermal fibroblasts on day 8 (both P < 0.05). Elevated level of TGF-betal was observed in all coculture supematants on day 8 (all P < 0.01) and in the supernatants of coculture system with a density ratio of 1/1 on day 4 (P < 0.05). There was no significant correlation between the expression level of TGF-betal and hydroxyproline in the coculture supernatants (r = 0.108, P ＞ 0.05). Conclusion In vitro coculture with mdMSC can increase the production of hydroxyproline and TGF-betal by fibroblasts, which may be a mechanism underlying the facilitation of skin repair by mdMSC.

Objective To investigate the clinical features of divergence paralysis improve the diagnostic and therapeutic ability,and evaluate the effect of surgical and non-surgical treatment.Methods It was a retrospective case series study.11 cases with complete data,diagnosed and treated as divergence paralysis in Tianjin Eye Hospital from September 2014 to January 2016,were summarized.The observation items included general date,neurologica consultation,comprehensive eye examination,and the eye position and movement,deviation degree,binocular vision,AC / A,diplopia examination of pre-treatment and post-treatment.The patients were followed up from 3 months to 1.5 yeas,averaged 6.9 months.Results In our study,1 patient was MillerFisher syndrome,3 cases had a history of hypertension,and 1 case had the history of intaking sleeping pills for about 3 months.The rest of the patients denied the nervous system disease,cardiovascular disease and other medical history.All patients complained about uncrossed diplopia only at distance.All of the 11 patients had a sudden onset of their symptoms.Each patient was examined by same neurologist,meanwhile MRI or CT were performed.All the results showed normal.All patients had refractive error.The angle of esotropia for distance of 5 meters was from + 25 △ to + 55 △ and was from + 8 △ to + 40△ for near(33 cm)before treatment while changed into-4△ ～ + 12△ for distance (5m) and to-8△ ～ +8△ for near (33 cm) after treatment.The ratio of AC / A ranged from 1.3 to 4.0,with an average of 2.6.Conclusion The clinical characteristics of divergence paralysis are a greater angle of esotropia and ipsilateral diplopia.Lateral rectns resection and non-surgical treatment have better effects on the improvement of diplopia and esotropia.

BACKGROUND: Parkinson disease(PD) is a series of clinical symptom induced by decreased dopamine (DA) in the striatum due to nigral dopaminergic neuronal degeneration. The intracerebral transplantation of secretory DA can reverse or improve the symptoms to a certain extent, but immunologic rejection is still existed.OBJECTIVE: To probe into cell transplantation with immunoisolation in treatment of in rats without application of immunosuppress and observe its mechanical intensity and the biocompatibility of microcapsule .DESIGN: Randomized controlled experiment was designed.SETTING: Biomedical Material Engineering Group, Dalian Institute of ChemicalPhysics , Chinese Academy of Sciences, and Department of Neurology, Second Hospital of Jilin University.MATERIALS: The experiment was performed in Animal Experimental Center of Second Hospital of Jilin University from August 2003 to February 2004, in which, 40 male Wistar rats were employed. PC12 cell was provided from Shanghai Institute of Cellular Biology of Chinese Academy of Sciences.METHODS: 6-hydroxydopamine solution was infused in the striatum to prepare animal model of Parkinson disease. Twenty-five rats of those had been prepared successfully and were randomized into microencapsulated cell transplantation group (12 rats), in which, 25 μL cell-loading sodium alginate-chitosan-solium alginate(ACA)microencapsul suspension (equal to 2.5×104 cells) was injected stereotaxically on two points of the right (affected side) striatum of animal model; non-microencapsulated cell transplantation group (7 rats), in which, 25 μL PC12 cell suspension (equal to 5×104cells) was injected; and empty microcapsul transplantation group (6 rats),in which, 25 μL empty microcapsules suspension was injected . On the 7th day after transplantation, in every group, apomorphine (APO) prepared with saline solution was injected (0.05 mg/kg) subcutaneously in the neck; afterwards, the revolving behavior was recorded for each rat, once per week,totally for 12 weeks. In the 12th week after operation, the rats were sacrificed with anesthesia. The brain tissue was collected for pathological observation and microcapsule were retrieved to evaluation of biocompatibility and immunoisolation.numbers before and after transplantation of each group.RESULTS:Twenty-five rats entered result analysis and the rest was sule: the retrieved ACA microcapsule was integrative in morphology,munoisolation of microcapsule: microencapsuled PC12 cells were prolifercycles before and after transplantation of each group: the records of lateral revolving of rats in every group before transplantation were not significantly different (P ＞ 0.05). In microencapsuled cell transplantation group, 2weeks later, the average number of revolving was significantly lower than that before the transplantation, or even the revolving stopped; the improved symptoms were maintained till the 12th week after transplantation. In nonmicroencapsulated cell transplantation group, the average revolving number was also significantly lower than that before the transplantation, but that on the 8th and 12th weeks was in tendency of increase, without obvious change compared with that before the transplantation (P ＞ 0.05). The revolving number before and after transplantation in non-microencapsulated transplantation group was similar[(10.5±1.4), (10.5±1.3) cyclos/min, P ＞ 0.05].microcapsule provides immune protection. The grafted encapsulated PC12cells survive for along term in the brain of rats with PD, maintain continuously the normal physiological function and improve the symptoms of PD by synthesizing and releasing DA.
