Objective To design an integrated emergency medical treatment system mounted on helicopter, which can meet the requirements of field treatment and evacuation in emergency disasters or local wars, the system has immobile form and mobile form. Methods With the characteristics of existing helicopter considered, the components of the system were supposed to include a universal stretchers, overall structure and embedded emergency devices and support transport accessories. Results The system could realize the destination of swift response and air-and ground first-aid, the new model of swift response can made the regulation and principle of first -aid more reasonable, and increases the survival rate significantly. Conclusion Critical diseases have become the latest killer in daily life. The first-aid on spot need the new model of swift response and air -and ground first -aid, the system can decrease the invalidity and mortality.

Objective To report the clinical and genetic characteristics of a dentatorubralpallidoluysian atrophy (DRPLA) pedigree with an onset of cognitive impairment.Methods Clinical data of this pedigree was collected.The numbers of CAG repeats in the exon 5 of atrophin-1 (ATN1) gene were analysed in the proband and the other 4 healthy family individuals.The polymerase chain reaction (PCR) products of the proband underwent cloning-sequencing using an original TA cloning kit.Results There were 5 patients in this family,4 with onset in adult and one in childhood.The proband had an onset manifestation of cognitive impairment,while the other 3 adult patients presented with ataxia.The two-year-old child in the pedigree had myoclonic epilepsy.The proband had 61 CAG repeats in the exon 5 of ATN1 gene.After TA cloning-sequencing of the proband ' s PCR products,there were 2 different numbers of CAG repeats,including 61 and 64.Conclusions The clinical manifestations of DRPLA can have obvious heterogeneity in one family.Some patients present with cognitive impairment.It is very important to test the numbers of CAG repeats of ATN1 gen for DRPLA diagnosis.Somatic mosaicism may be also observed in Chinese DRPLA patients.

This paper introduces a type of anaesthesia workstation which is composed of two vertical medical chests, i.e. the upper and lower parts. Taken out of the chest, the two parts are butted against and locked to make the workstation ready for operation. After operation is finished, the two parts are uncoupled and put into the chests, and then the workstation can be stored and transported with the chests closed.

Objective To investigate the nuclear factor-erythroid 2-related factor (Nrf-2),and heme oxidase 1 (HO-1) expression in acute lung injury induced by paraquat poisoning in rats and explore the mechanism of lipoic acid acting on protection of lung from paraquat poisoning.Methods Seventy-two adult healthy male Sprague Dawley (SD) rats were randomly divided into three groups with different treatments designated as:control group (control group,n =12),paraquat group (PQ group,n =30) and paraquat + lipoic acid group (LA group,n =30).PQ group and LA group were randomly divided into five subgroups (n =6 in each) according to 6 h,12 h,24 h,48 h and 72 h after modeling and treatment.The rats in PQ group and PQ + LA group were treated with intra-peritoneal injection (ip) of PQ (25 mg/kg),while the rats in control group were treated with the equal volume of saline instead.Half an hours after intra-peritoneal injection of PQ,lipoic acid (100 mg/kg) was injected into caudal vein of rats once a day until they were sacrificed.The body weight was measured everyday.The rats of each group were sacrificed at the given intervals,and lung tissues were harvested to measure lung coefficient of rats.The same part of left lung of rats in each group was taken for HE staining and immunohistochemistry in order to detect the expressions of Nrf2 and HO-1.The right lung of rats in each group was taken for the detection of GSH-Px and SOD activity.All data were analyzed by using the One-way analysis of variance (ANOVA) and SNK-q test.Results The body weight reduction in LA group (191.02 ± 0.82) g,(183.37 ± 7.74) g was significantly less than that in PQ group (183.85 ± 2.07) g,(173.13 ± 4.34) g at 48 h and 72 h after PQ poisoning,respectively (P ＜ 0.01,P ＜ 0.05).The lung coefficient in LA group (6.83 ± 0.48) mg/g,(7.61 ±0.28) mg/g,(8.29 ±0.36) mg/g was less compared with PQ group (7.39 ±0.53) mg/g,(8.48±0.23) mg/g,(9.06±0.10) mg/g at 24 h,48 h,and 72 h,respectively (P＜0.01,P＜ 0.05).The immunohistochemical expressions of Nrf-2 in LA group (3.99 ±0.50),(3.51 ±0.12) were higher than those in PQ group (1.33 ±0.22),(1.62 ±0.41) at 48 h and 72 h.The immunohistochemical expression of HO-1 in LA group (1.76 ±0.17) was higher than that in PQ group (1.31 ±0.15) at 72 h.The levels of GSH-Px activity in LA group were significantly higher in comparison with PQ group at 24h,48h,and 72h (P ＜0.01,P ＜0.05).The levels of SOD activity in the LA group were significantly higher in comparison with PQ group at 6 h,12 h,24 h,48 h,and 72 h after PQ administration (P ＜ 0.01).Conclusions Nrf2-ARE (antioxidant response element) signaling pathway is involved in the pathogenesis of acute lung injury induced by paraquat poisoning,and lipoic acid may protect acute lung injury in rats induced by paraquat poisoning through Nrf2-ARE signaling pathway.

Objective To evaluate the clinical effect of lung transplantation for pediatric pulmonary artery hypertension (PAH).Methods The recepter 1 and 2 with idiopathic pulmonary artery hypertension (IPAH) were diagnosed by right catheterization.The heart fuction was NYHA IV.The pulmonary artery pressure and mean pulmonary artery pressure were 110/70mmHg and 148/72 mmHg respectively.They underwent bilateral sequential lung transplantation with extracorporeal membrane oxygenation (ECMO) support.During operation,the ECMO support time was 550 min and 450 min and the blood loss was 3000 ml and 1200 ml respectively.The recepter 3 with end-stage congenital ventricular septal defect with Eisenmenger syndrome (ES) who had received open heart exploration underwent right single lung transplantation and ventricular septal defect repair under cardiopulmoanry bypass(CPB).There were ventricular septal defect and bidirectional shunt through UCG assessment The pulmonary artery pressure and mean pulmonary artery pressure were 110/60 mmHg.CPB time was 244 min.The three recepters had the same ABO blood group and the similar body type with the three donors.Results The recepter 1 and 2 was sustained by ECMO after operation for 16 h and 13h respectively.But unstable hemadynamics and acute left heart failure occured on 3rd and 4th day after the operation respectively.We treated them with ventilate support and tracheotomy on 3rd and 6th day respectively.They were also treated with cardiotonic; dieresis and the patients were weaned away from the ventilation on 33rd and 12ed day after the operation respectively.The transplanted lung of the receptor 3 had pneumochysis in the first 3 days.The patient was treated with ventilate support and tracheotomy on 7th day and was weaned from the ventilation on 12ed day after the operation.An acute rejection episode occurred on 14th day.The cordioform and heart function of the three cases improved and especially the receptor 3 had intact repaired of ventricular septal defect.They were discharged from the hospital on 93rd,32ed and 62ed day afer the operation.The heart function all reached NYHA I and the pulmonary artery pressure and mean pulmonary artery pressure was reduced to 54/32 mmHg,60/36 mmHg and 53/39 mmHg respectively.The three cases have been followed up for 41 months,21 months,and 82 months.They are having an excellent quality life.Conclusion Lung transplantation is effective to improve the quality of life for end-stage pediatric pulmonary artery hypertension even with slight right ventricular dysfunction with satisfying short-term results.
