Objective To improve the clinical practice ability and the comprehensive ability to assist in the rescue of the medical staff by the medical cooperation mode.Methods 30 nurses and 12 doctors in department of emergency were divided into 6 combinations and 4 combinations,each group consisted of 1-2 doctors and several nurses,who following the 2010 USA Heart Association guidelines for cardiopulmonary resuscitation and emergency cardiovascular care and America Heart Association advanced cardiovascular life support curriculum (AHA ACLS) training method.Theory teaching and Sub skill practice and Comprehensive simulation training and Summarize and analyze the feedback pattern,training,exercises and assessment to rescue patients with sudden cardiac respiratory arrest of simulations were carried out with the team combat form in scenario.Results Implementation of health cooperation cardiopulmonary resuscitation team training exercise improved the rescue team support ability.97.6％ (41/42) trainees were considered to improve the order of the rescue while 100.0％ (42/42) trainees were considered that this training model was worthy to popularize.Conclusions The medical cooperation cardiopulmonary resuscitation team training exercise improves the timeliness and comprehensive help rescue ability.

Objective To investigate the role of receptor for advanced glycation end - products nuclear factor - κB(RAGE - NF - κB)signaling pathway in the lipopolysaccharide - induced acute lung injury(ALI)in neo-natal rats. Methods Thirty - two SD rats were divided into 4 groups by complete randomization method(8 cases in each group).(1)Lipopolysaccharide(LPS)group was given intraperitoneal injection of 9 g/ L saline and 3 mg/ kg LPS 1 h later.(2)Bortezomib group was given intraperitoneal injection of Bortezomib(0. 2 mg/ kg)and 3 mg/ kg LPS 1 h later.(3)Anti - RAGE mAb group was given intraperitoneal injection of anti - RAGE mAb(15 mg/ kg)and 3 mg/ kg LPS 1 h later.(4)Control group was given 9 g/ L saline was given at each time point. All the rats were sacrificed and observed 24 h later. Levels of tumor necrosis factor(TNF) - α in the plasma and bronchoalveolar lavage fluid(BALF) were detected by enzyme linked immunosorbent assay. RAGE and NF - κB levels in tissue homogenates were detected by Western blot and mRNA levels were detected by reverse transcription - polymerase chain reaction. The pathological assessment of the lung tissues was performed by HE staining. Results (1)Among 4 groups,there were significantly differences in TNF - α in serum and BALF(F = 150. 70,P ﹤ 0. 001;F = 165. 83,P ﹤ 0. 001). Levels of TNF - α in LPS group were significantly higher than those of two pretreatment groups(all P ﹤ 0. 05).(2)Western blot figures il-lustrated that the concentrations of RAGE mRNA and NF - κB in anti - RAGE mAb group and bortezomib group were lower than those of the LPS group.(3)Reverse transcription - polymerase chain reaction analysis showed that there were significant differences in the expression of RAGE mRNA and NF - κB mRNA among 4 groups(F = 175. 14,P ﹤0. 05;F = 188. 65,P ﹤ 0. 05). Levels of RAGE mRNA and NF - κB mRNA in the LPS group were significantly higher than those of two pretreatment groups(all P ﹤ 0. 05).(4)Lung injury score differences among 4 groups were statistical-ly significant(F = 106. 01,P ﹤ 0. 001). Pathological changes in two pretreatment groups reduced compared to those of the LPS group(all P ﹤ 0. 05). Conclusions RAGE - NF - κB signaling pathway regulates the LPS - induced ALI in neonatal rats. Anti - RAGE mAb and Bortezomib both have a protective effect on LPS - induced ALI.

ObjectiveTo explore and establish the liver injury risk prediction model of indirect toxicity of Chinese medicinals under the condition of compound formulas， and provide new ideas and methods for the study of evaluation of liver injury of Chinese medicinals based on indirect toxicity. MethodsTaking Buguzhi （Fructus Psoraleae） pre-parations as model drug， the combined Chinese medicinals with Buguzhi （Fructus Psoraleae） of high frequency are screened out， and their components and action targets were obtained through TCMSP， TCMIP and PharmMapper databases. The association strength value and risk value of Chinese medicinals that acted on the nuclear factor κB （NF-κB） pathway were analyzed. For those having greater values than the median association strength value and risk value were regarded as indirect Chinese medicinals of liver injury risk. In this way， a prediction model of liver injury risk of Chinese medicinals was constructed based on immune activation-related indirect liver injury process （taking NF-κB pathway as an example）. And verification of the prediction model was performed using Heshouwu （Radix Polygoni Multiflori） preparations. ResultsThe prediction model of liver injury risk based on important immunoactivated pathway （taking NF-κB pathway as an example） found that Yinyanghuo （Herba Epimedii） （association strength value = 0.18， risk value = 0.25） was a Chinese medicinal with potential risk of indirect liver injury within Buguzhi （Fructus Psoraleae） prepartions， which may increase the risk of liver injury by positively regulating Bruton's tyrosine kinase （Btk） and protein kinase C theta （PKCθ） on NF-κB pathway. Further verification of prediction model by Heshouwu （Radix Polygoni Multiflori） preparations showed that Buguzhi （Fructus Psoraleae） （association strength value = 0.25， risk value = 0.33） and Tusizi （Semen Cuscutae） （Semen Cuscutae， association strength value = 0.34， risk value = 0.33） may increase the liver injury risk of Heshouzu. ConclusionThe liver injury risk prediction model of indirect toxicity of Chinese medicinals has been constructed in this study， providing metho-dological reference for the identification of Chinese medicinals of indirect liver injury risk under the condition of compound formulas.

Objective: To investigate the feasibility of long noncoding RNA (lncRNA)_AK096792 as a clinical predictor of bronchopulmonary dysplasia (BPD) in preterm infants. Methods: All the cord blood(2-5 mL) of very low birth weight (VLBW) preterm infants born in Huai′an First Hospital Affiliated to Nanjing Medical University were collected from December 1, 2015 to December 1, 2017.Moreover, the peripheral blood(2 mL) of those VLBW infants diagnosed with BPD was also collected.A total of 36 infants with BPD were collected.Another 36 cases of premature children with VLBW were chosen as control group according to random number table.The relative content of lncRNA_AK096792 in cord blood and peripheral blood was detected by using real-time quantitative PCR (qPCR). Additionally, the correlation of lncRNA_AK096792 levels between cord and peripheral blood of BPD infants was analyzed.The sensitivity and specificity of lncRNA_AK096792 for BPD were analyzed by using receiver operating curve test. Results: (1)LncRNA_AK096792 was a common, evolutionarily conserved, non-coding RNA present in both mouse and human.(2) The expression level of lncRNA_AK096792 in peripheral blood was significantly higher than that in cord blood in BPD group[(463.3±352.0)% vs.(50.0±37.5)%], and the difference was significant(P<0.001), and they were highly correlated (r=0.825, P<0.001). (3) The level of lncRNA_AK096792 in cord blood in BPD group was signi-ficantly higher than that in non-BPD group [(484.3±280.5)% vs.(101.2±28.6)%], and the difference was significant(P<0.001). (4)When lncRNA_AK096792 served as a clinical predictor for BPD, the specificity was 83.3%, the sensitivity was 75.6%, and an area under the receiver operating characteristic curve was 0.88(P<0.001). Conclusions LncRNA_AK096792 is highly correlated with the development of BPD.The level of lncRNA_AK096792 in umbilical cord blood of premature infants can be used as an early predictive marker for BPD, it calls for further study.
