Objective To perform APACHEⅡand SOFA in assessmentof EICU patients with sepsis ,and analyze the risk factors. Methods A retrospective analysis from January 2014 to October 2015 in EICU of our hos-pital ,a total of 83 patients suffered from sepsis ,including sepsis group(30 cases)and septic shock(53 cases). PCT,PT,APTT,lactic acid,mechanical ventilation time and APACHE Ⅱ and SOFA score were collected, through the receiver-operating characteristic curve(ROC)index to predict the prognosis of patients with sepsis.Re-sults The mortality of the patients in the septic shock group,PT,APTT,APACHEⅡ,SOFA score,mechanical ventilation time and PCT were significantly higher than thosein the sepsis group(P<0.001). APTT,APACHEⅡ, SOFA score and mechanical ventilation time had significant difference (P ≤ 0.001) between survival and dead. The lactic acid level of the dead group was significantly higher than that in the survival group(P=0.038). The ar-ea under curve(AUC=0.806)of APACHEⅡscore was better than the SOFA score(AUC=0.765).The outcome of sepsis had correlation with APACHEⅡ,SOFA score,lactic acid,and mechanical ventilation time(P<0.05). Conclusion APACHE II and SOFA scores can accurately predict mortalityoutcome in emergency intensive care units patients with sepsis,especially the APACHEⅡscore.We can measure blood coagulation function,APACHEⅡ,SOFA score,PCT,lactic acid and mechanical ventilation time to assess the severity of patients with sepsis.

Objective To explore and establish the effective model of assessment for residen-cy training. Methods Totally 181 residents completed general specialist stage of resident training of Liaoning province in 2010. Assessment process was designed and implemented for general specialist training stage, including theory exam (basic knowledge, professional knowledge and public knowledge) and objective structured clinical examination (OSCE) (standardized patient(SP), computer-based case simulations(CCS) and clinical skills operation). T test and variance analysis were used and P≤0.05 stands for statistically significant difference. Results The total results consisted of two parts, theory examination results (40.00%) and OSCE results (60.00%) and two students failed the examination. The mean score of OSCE was up to standard (66.58±5.50). The mean score of SP and CCS was close to standard. The mean score of clinical skills operation reached a good level. In terms of the OSCE, SP examination and CCS examination, the performance of residents from the two universities had sig-nificant difference (t=3.818, P=0.000; t=5.581, P=0.000; t=5.419, P=0.013) and the performance of residents from the five hospitals also had significant differences. Conclusions The assessment of standardized resident training is improving gradually. Through the widespread application of OSCE in the assessment;it could be helpful to the clinical training of residents.

Stage assessment is an important part of standardized resident training.After two years of practice and exploration,Liaoning had established the complete examination and evaluation system including the theory test and skill test and this system was future improved through analyzing two years' results and summing up the experiences making it more suitable for residency training in the future.

Objective To explore the value of dexamethasone(DEX) for neuronal cell injury and death by observing the effect of DEX on excitatory amino acid(EAA) and monoamine neurotransmitter in cerebral tissue of neonatal rat with hypoxia-ischemia.Methods Hypoxic-ischemic neonatal rat models were established,the levels of EAA and monoamine neurotransmitter in cerebral tissue were analyzed by using capillary electrophoresis and fluorospectrophotometry method.The rats were divided into 4 groups: small dose DEX group pre-treated with DEX(0.5 mg/kg) prior to hypoxia-ischemia,large dose DEX group pre-treated with DEX(10 mg/kg) prior to hypoxia-ischemia,HIE group and shamful operation group.Results The levels of EAA and monoamine neurotransmitter contents in HIE group were significantly higher than those in shamful operation group(P0.05).EAA contents of large dose DEX group greatly decreased compared with HIE group (P

The aim of this study was to evaluate the effects of compound probiotics on milk performance,blood biochemical indexes,rumen fermentation parameters and nutrient digestibility of Holstein dairy cows in middle-and-later lactation.Forty-eight dairy cows with similar milk yield,days in milk and age were randomly divided into 4 groups treated with four different levels of compound probiotics as follows:the control group (0 g/d),group 1 (10 g/d),group 2 (20 g/d) and group 3 (30 g/d).The adaptation period was 7 days,and the total experimental period was 60 days.Results showed that:compared with the control group,supplementation of compound probiotics could improve milk yield and significantly increase the concentration of milk protein,lactose and total solids (P＜0.05);there was no significant effect on blood biochemical indexes (P＞ 0.05);compound probiotics could significantly increase the content of ammonia and microbial protein content (MCP) in the rumen (P＜ 0.05);the apparent nutrient digestibility of crude protein and crude fat of group 2 was significantly higher than other groups (P＜0.05);compared with the control group,the economic benefits of group 1,2,3 increased 2.28,4.80 and 4.09 yuan/d,respectively.In summary,dietary supplementation with 20 g/d of compound probiotics was the most effective method for milk performance,rumen fermentation parameters,nutrients apparent digestibility and economic benefit of Holstein dairy cows.

Objective To refine the technique and improve the efficacy of seminal vesiculoscopy in the diagnosis and treatment of seminal vesicle disease.Methods The refined techniques of seminal vesculoscopy,using a patent catheter into the slit-like ejaculatory duct orifice through the verumontanum and another patent catheter introduced into seminal vesicle lumen,were performed in 58 cases,including intractable hematospermia in 42 cases and azoospermia in 16 cases.Results Seminal vesiculoscopy was successfully entered into the seminal vesicular lumen in 46 patients (79％) within 2-3 min.There was no obvious ejaculatory duct orifice in 12 of 16 azoopermia cases,and transurethral resection of verumontanum was performed,then seminal vesiculoscope was directly entered into seminal vesicle lumen.Symptoms of hematospermia were disappeared in 25 cases (60％),improved in 11 cases (26％),and azoospermia were cured in 6 cases (37％),improved in 5 (31％),unchanged in 5 (31％) during the follow-up period of 6-36 months (average 18 months).There were no major or minor complications in this series,and no urine reflux into ejaculatory duct in 19 cases demonstrated by contrast medium.Conclusion Refined seminal vesiculoscopy was technically safe,efficient,simple,and potentially widely used in the cases of hematospermia and ejaculatory duct obstructions.

Objective To investigate the effects of intrathecal morphine remote preconditioning (MRPC) on protein-serine-threonine kinases-endothelial nitric oxide synthase (Akt/eNOS) signaling pathways and cardiac myocyte apoptosis in rats.Methods Male SD rats weighing 280-320 g were used in this study.A needle was inserted through a surgically created hole into the sub-dural space of spinal cord.Thirty-six rats in which intrathecal needle was successfully placed without complication were randomly divided into 3 groups (n =12 in each).In group Ⅰ sham operation was performed (Sham).In group Ⅱ myocardial I/R was produced (I/R).In group Ⅲ morphine was given intrathecally in 3 repeated doses of 1 μg/kg at 5 min intervals before ischemia (MRPC).Myocardial I/R was produced by occlusion of left anterior descending branch (LAD) of coronary artery for 30 min followed by 120 min reperfusion.The animals were then sacrificed and hearts removed for measurement of area at risk (AAR) and infarct size area (IS).IS/AAR ratio was calculated.Myocardial apoptosis was detected by TUNEL and apoptotic index (the number of apoptotic myocardial cells/the total number of myocardial cells) was calculated.The levels of Akt,phosphorylated Akt (p-Akt) and eNOS was determined by Western blot.Results The infarct size,myocardial cell apoptotic index and pAkt level were higher and eNOS level was significantly lower in I/R group than those in group Sham (P ＜ 0.01).MRPC significantly reduced the infarct size and myocardial cell apoptotic index,and pAkt and eNOS level up-regulated in group RMPC compared with group I/R (P ＜ 0.01).Conclusions Akt/eNOS signaling pathways probably participate in the protective effects of intrathecal morphine remote preconditioning against myocardial I/R injury and myocardial cell apoptosis in rats.

The purpose of this study is to investigate the enantioselectivity of norgestrel (NG) transdermal permeation and the potential influence of linalool and lipids on the enantioselectivity. In vitro skin permeation studies of NG across the excised rat skins were performed with Valia-Chien diffusion cells, and the permeation samples were analyzed by enantioselective HPLC. The possible enantioselective permeation of NG across intact rat back skin and lipids extracted rat back skin and the influence of linalool were evaluated. The skin permeation rate of dl-NG was two times higher than that of l-NG when donor solutions (EtOH/H2O 2 : 8, v/v) containing l-NG or dl-NG. It may be mainly attributed to the solubility discrepancy between enantiomer and racemate. The enantioselective permeation of dl-NG across intact rat skin was observed when the donor solutions containing dl-linalool. The permeation flux of l-NG was 22% higher than that of d-NG. But interestingly, the enantioselective permeation of dl-NG disappeared under the same experimental condition except that the lipid extracted rat skin was used. Attenuated total reflection-fourier transform infrared spectroscopy analysis of stratum corneum showed that the wave number for asymmetric CH2 stretching vibrations of lipids treated with dl-linalool was greater than that of the control. The results indicated that the enantioselective permeation of NG may be contributed by the interaction between dl-linalool and lipids. More than half of lipids were composed of ceramides. The stereospecific interaction maybe existed among chiral enhancer (linalool), lipids (ceramides) and/or chiral drugs (NG).
