Objective To effectually record cardiopulmonary resuscitation (CPR) procedure, analyze and compare the CPR performance of all medical and nursing staffs to find out the existed information for the improvement of the quality of CPR and its survival rate. Methods The medical data were collected according to the Utstein Criteria and CPR event was automatically recorded by a digital video-recording system, by which hands-off times within 10 minutes of CPR and times for installation of chest compression machine, establishment of endotracheal intubation and establishment of the venous channel were analyzed. Multiple regression analysis was conducted to analyze the factors affecting CPR effect. Results ① During the period from December 2009 to December 2015, a total of 376 patients with cardiac arrest (CA) was registered, including 248 males and 128 females, with a median age of 68 (53, 78) years. Estimated median time interval from CA to CPR initiation was 5.0 (0.1, 20.0) minutes and there were 189 cases less than or equal to 5 minutes. The acute myocardial infarction (AMI) with 145 cases (38.6%) was the main etiology of CA. Initial shockable rhythm was found in 16 patients (7.0%) out of 230 out-of-hospital cardiac arrest (OHCA) patients, of whom 13 underwent ventricular fibrillation (5.7%), 3 underwent ventricular tachycardia (1.3%). Initial shockable rhythm was found in 47 patients (32.2%) out of 146 in-hospital cardiac arrest (IHCA) patients, of whom 40 underwent ventricular fibrillation (27.4%), and 7 underwent ventricular tachycardia (4.8%). CPR by a mechanical device (Thumper) was performed in 219 patients (58.2%). In 376 patients, 186 patients had return of spontaneous circulation (ROSC, 49.5%), a successful CPR (ROSC ≥ 24 hours) was found in 110 patients (29.3%), 99 patients was hospitalized alive (26.3%) and 40 patients were discharged alive (10.6%). In 146 cases of IHCA, 89 patients had ROSC (61.0%), a successful CPR was found in 63 patients (43.2%), 56 patients were hospitalized alive (38.4%), and 29 patients were discharged alive (19.9%). In 230 patients of OHCA, 89 patients had ROSC (38.7%), 65 patients received pre-hospital CPR (28.3%), a successful CPR was found in 47 patients (20.4%), 43 patients were hospitalized alive (18.7%), and 11 patients were discharged alive (4.8%). There were 37 patients had a successful CPR (69.8%), and 25 patients were discharged alive (47.2%) in 53 patients with ventricular fibrillation. ② There were 77 patients with valid video information for analysis of CPR performance, with 48 patients of OHCA, and 29 patients of IHCA. Delay median time from the patients presence in the resuscitation room to be placed in rescue bed was 22 (0, 33) seconds. Hands-off median times during 10 minutes of CPR was 41 (18, 90) seconds. Thumper installment median times was 43 (31, 69) seconds. Median time for endotracheal intubation was 59 (35, 109) seconds. Median time of venous catheter placement was 112 (70, 165) seconds. It was shown by multivariate regression analysis that there was a significant correlation between estimated time interval from CA to CPR performed, hands-off time and success rate of CPR (t1 = -3.452, t2 = -2.729), rate of discharge alive (t1 = -2.328, t2 = -2.736, all P < 0.05). In 48 OHCA patients, success rate of CPR was significantly correlated with estimated time interval from collapse to CPR performed (t = -2.409, P = 0.021). In 29 IHCA patients, success rate of CPR and rate of discharge alive was significantly correlated with hands-off times (t1 = -3.412, t2 = -2.536, both P < 0.05). Conclusions Survival to hospital discharge following CA is significantly correlated with the time interval from collapse to CPR performed and hands-off times in CPR. Installment and usage of Thumper should be postponed in order to reduce hands-off times during CPR in IHCA.

And the inhibition ratio of retortion of mice by 0.6%acetic acid was 50.5%,68.8%,58.1%,respectively, at the high,medium and low dose groups. In addition,the high,medium and low dose groups reduced the pain reaction latency of mice in the hot-plate tests. Conclusion Chaigeshubiao granules have antipyretic,anti-inflammatory and analgesic actions.

Objective To develop a real-time fluorescence quantitative PCR method for detection of Legionella pneumophila as a tool for environmental and clinical examination. Methods A pair of degen-erated primers and one TaqMan-MGB probe were designed to test the conserved region at the macrophage in-fective potentiation (mip) gene of Legionella pneumophila. TaqMan MGB real-time quantitative PCR assay was developed with pMD-19T plasmid including mip gene of Legionella pneumophila as standard sample. The sensitivity and specificity of the real-time quantitative PCR was evaluated using the standard sample and dif-ferent strains. Results The detection limit of 0.71 copy/μl was obtained for the standard sample in a reac-tion system of 0.6μl of sense and antisense primers (20μmol/L), respectively, 0.4μl of probe (20μmol/L) and 6.0μl of DNA temple. Conditions for the PCR reactions were as follows. After an initial de-naturation at 95℃ for 20s, 40 amplification cycles were performed. Each cycle consisted of denaturation at 95℃ for 10 s, primer annealing at 50℃ for45s. The PCR Ct value of a standard strain and 12 isolates was in a scale of 13.23 and 16.04. However, the Ct values of the strains of Staphylococcus aureus, Salmonella typhimurium, Vibrio parahaemolyticus, Escherichia coli, Pseudomonas aeruginosa and Shigella sonnei were greater than 30. Conclusion The real-time quantitative PCR method has good sensitivity and specificity and the result has potentiality of applying for detecting Legionella pneumophila.

PURPOSE: The purpose of the present study was to investigate the aberrance of histone H3 lysine 4 trimethylation (H3K4me3) in patients with IgA Nephropathy (IgAN). MATERIALS AND METHODS: In this study, H3K4me3 variations in peripheral blood mononuclear cells (PBMCs) from 15 IgAN patients and 15 healthy subjects were analyzed using chromatin immunoprecipitation linked to microarrays analysis (ChIP-chip). ChIP real-time PCR was used to validate the microarray results. Expression analysis by quantitative real-time PCR (qRT-PCR) revealed correlations between mRNA and H3K4me3 levels. DNA methylation status was analyzed by quantitative methylation-specific PCR. RESULTS: We found that 321 probes displayed significant H3K4me3 differences in IgAN patients compared with healthy controls. Among these probes, 154 probes displayed increased H3K4me3 and 167 probes demonstrated decreased H3K4me3. For further validation, we selected 4 key relevant genes (FCRL4, GALK2, PTPRN2 and IL1RAPL1) to study. The results of ChIP real-time PCR coincided well with the microarray data. Quantitative RT-PCR revealed the correlations between the mRNA expression and the methylation levels of H3K4me3. Different degrees of DNA methylation alterations appeared on the selected positive genes. CONCLUSION: Our studies indicated that there were significant alterations in H3K4me3 in IgAN patients. These findings may help to explain the disturbed immunity and abnormal glycosylation involved in IgAN patients.
