Objective To learn the present pre-hospital emergency resources allocation in Liaoning province.Methods Site survey and questionnaire survey were used to survey the basic information,number of pre-hospital emergency ambulances,human resources,and communication/control systems of 19 pre-hospital emergency centers in Liaoning province in 2014.Results The number of pre-hospital emergency sub-stations,ambulances and human resource fall short of demand.Furthermore,these resources are found with such problems as greater service radius of average pre-hospital emergency service and longer average pre-hospital response time in countryside than cities,insufficient and obsolete ambulances short of onboard equipment and communication systems,not to mention shortage of medical workers of higher degrees and academic titles.Conclusions A great gap is found between urban and rural pre-hospital emergency resource allocation in Liaoning province,with poor resources in the countryside.The government is recommended to step up financial support in increasing pre-hospital emergency substations and resources allocation,regularly update pre-hospital emergency vehicles,set up independent title promotion mechanism,perfect communication scheduling system,in order to satisfy the demands of pre-hospital first aid.

Objective To investigate the effect of penehyclidine hydrochloride (PHC) on iNOS expression in lung in septic mice.Methods Female KM mice were subjected to cecal ligation and puncture (CLP,a model of polymicrobial sepsis) or shame operation.Thirty-six KM mice weighing 20～25 g were randomly assigned into three groups:shame CLP group,CLP group and PHC group.Mice in PHC group were given PHC 0.45 mg/kg intraperitoneally at 1 h before CLP. Six hours after CLP,the lungs of each group were sampled for light and electronic microscopy.The expression of iNOS mRNA in lung tissue were detected by in situ hybridization.The survival rates were observed at 24 h after the operation. Results The CLP group was observed thickened alveolar septa,as well as mitochondrial cristae swelling and mitochondrial vacuolation under electronic microscope.Emptied lamellar bodies could be also found.Histology of lung in PHC group had little changed.Expression of iNOS in lung in PHC group was significantly lower than that of the CLP group.At 24 h after CLP challenge,70.0% of the PHC mice lived,remarkably increased compared with that of the CLP group (26.7%),P＜0.05.Conclusion PHC had effective effect for increasing the survival rates of septic mice,inhibiting the expression of iNOS and reducing the severity of lung injury.

Objective To assess the efficacy and safety of argon plasma coagulation(APC) in treating patients with Barrett's esophagus.Methods Two reviewers independently searched the Cochrane Library(Issue 2,2008),MEDLINE(January 1948 to November 2008),and CNKI(January 1999 to November 2008),respectively.The quality of the included studies was assessed according to the guidance in the Cochrane Handbook of systematic reviews of interventions.Results Six randomized controlled trials involving 253 patients with Barrett's esophagus met the inclusion criteria and were included.One trial reported that the ablation rate of patients in the APC group was significantly higher than that in the endoscopic surveillance group.Followed up one year,the ablation rate in APC group was 63% compared with 15% in the control group(P

Using MS as basic medium, supplemented with 1.0 mg · L(-1) IBA, the adventitious roots of Tripterygium wilfordii were induced, and the good adventitious root culture system was established by leaves or callus induced by leaves as explants. The adventitious roots were also induced with 2.0-4.0 mg · L(-1) NAA and the good adventitious root culture system established by using suspension cells from callus as materials to induce adventitious root. The content of triptolide of three adventitious roots culture system were exceeded in the natural root bark. The content of triptolide of AR3 adventitious roots was the highest about 5.3 times as that in the natural root bark. By using 5 L stirred fermentor during pilot enlarge cultivation, compared with 250 mL flask cultivation, the adventitious roots increment and secondary metabolites content per liter medium showed no significant difference. The accomplishment of this analysis laid a foundation by tissue culture production of the secondary metabolites of T. wilfordii.

Objective To compare the clinical characteristics and the outcomes of severe hyperlipidemic pancreatitis (SHLP) and severe acute gallstone pancreatitis (SAGP).Methods The clinical data of 22 patients with SHLP and 91 patients with SAGP admitted from January 2009 to December 2015 were retrospectively reviewed.The clinical manifestations,laboratory tests,organ dysfunction,medical treatment,complications and outcomes in 30 d after admission were analyzed and compared between two groups of patients.Results There were 16 males and 6 females with a mean age of (60.5 ± 9.1) years in SHLP group;while 32 males and 59 females with a mean age of (54.3 ± 5.4) years in SAGP group.The blood and urine amylase levels in SHLP group were significantly lower than those in SAGP group [(715 ±99) U/L vs.(1 551 ± 107) U/L,t =4.65,P =0.00;(382 ±56) U/L vs.(773 ± 66) U/L,t =4.52,P =0.00,respectively].The incidence of circulation insufficiency,respiratory insufficiency,renal dysfunction,and long-term puhnonary infection in SHAP patients was significantly higher than that in SAGP patients [36 ％ (8/22) vs.14 ％ (13/91),x2 =5.22,P =0.01;41％ (9/22) vs.7 ％ (6/91),x2 =9.46,P =0.01;23％(51/22) vs.5％ (5/91),x2 =4.20,P=0.03;55％(12/22) vs.32％ (29/91),x2 =7.02,P =0.01].Two cases died in the SHLP group and 9 cases died in SAGP group due to critical infection,cardiac events and bleeding.Conclusion Compared to SAGP patients,the blood and urine amylase levels are usually not remarkably high in SHLP patients,and the prevention and management of multi-organ failure and lung infection are more important for SHLP patients.

Objective To identify genes associated with hepatocellular carcinoma (HCC) as candidate diagnostic markers in a genome-wide scale. Methods The gene expression profiles of 40 pairs of HCC tumor tissue and peripheral non-tumorous liver tissue were analyzed by using gene chip technology.The gene chips were fabricated at the National Cancer Institute (NCI). Each gene chip contained 9 180 genes. The fluorescent targets were prepared by a direct labeling approach using two kinds of fluorescences as following: 100 ?g of total RNA from non-cancerous liver tissue was labeled with Cy3-dUTP and 200 ?g of total RNA from HCC was labeled with Cy5-dUTP. The targets were mixed together and hybridized with genes on the gene chips. Unsupervised hierarchical clustering analysis was done by CLUSTER and TREEVIEW software using median centered correlation and complete linkage. Results A total of 10 genes were found up-regulated in over 80% of primary tumors comparing with that of their corresponding non-tumorous liver tissues at a two-fold filter with an unsupervised hierarchical clustering algorithm, including protocadherin-alpha 9, ESTs, Homo sapiens cDNA FLJ, KPNA2, RPS20, SNRPE, CDKN2A, UBD, MDK and ANXA2. Conclusion These genes are supposed to be candidates for the diagnosis of HCC. Further investigation of these genes in a large scale of patients with HCC and patients with non-malignant hepatic diseases will be needed to disclose whether they could be used clinically as novel diagnostic tumor markers for HCC.

PurposeTo explore the value of gemstone spectral imaging (GSI) in diagnosis of thyroid nodule hemorrhage.Materials and Methods Seventeen patients with surgery and pathology confirmed thyroid nodule hemorrhage underwent thyroid spectrum CT scan. The CT value, iodine concentration value, water concentration value and the effective atomic ordinal value as well as spectral curve slope of hemorrhagic nodules and surrounding normal thyroid tissue were measured respectively.Results Hemorrhagic thyroid nodules showed equal or high CT value, low concentration of iodine, high concentration of water, low spectral curve slope, and low effective atomic ordinal value on spectral CT imaging. There were statistically significant differences in concentration of iodine value, concentration of water value, and spectral curve slope between hemorrhagic nodules and surrounding normal thyroid tissue (Z=-5.438,-4.679 and-5.317,P<0.01), and there were statistically significant differences in CT value and effective atomic ordinal value (Z=-2.097 and-2.230,P<0.05).Conclusion Energy spectrum CT scan is important in detection and accurate diagnosis of thyroid nodule hemorrhage.
