Objective To investigate endoscropic assist in rat orotracheal intubation.Methods 40 rats were randomly divided into two groups.The procedure time, total time, intubation frequency,the success rate of the first intubation and the survival rate in 24h were compared between the conventional group and the endoscropic group.Results The total time in two groups were nearly the same.But the procedure time and frequency of intubation were significantly less in the endoscropic group than those in the conventional group.The success rate of the first intubation in the endoscropic group was obviously higher than that of the conventional group.There was no obviously difference between the survival rate after extubation in 24h between groups.Conclusion Endoscropic assist is superior to the conventional method and worth promoting.

Objective To investigate the influences of Xuebijing injection on organs' ultra-microstructure in septic shock rats. Methods Fifteen male Sprague-Dawley (SD) rats of clean grade were selected. According to the method of random digits table, all of them were divided into three groups: sham operation group, model group and Xuebijing treated group, 5 rats being in each group. Cecal ligation and puncture (CLP) was adopted to reproduce abdominal cavity infection leading to sepsis model formation. While the rats in sham operation group just underwent abdominal median incision, abdominal exploration and closure of abdominal wall after flipping retrocecal region. In the Xuebijing treated group, within 1 hour after the operation, Xuebijing injection (4 mL/kg) was transfused through the catheter inserted in the femoral vein, and then normal saline (2 mL·kg-1·h-1) was continuously transfused until the rat being sacrificed. In the sham operation group and model group, equal volume of normal saline was given after operation. The blood pressure of all the rats was monitored continuously by a pressure device connected with a catheter inserted in the right carotid artery. The rats were observed for 12 hours, afterwards they were sacrificed, the samples of heart, lung, kidney and liver were taken, and their ultrastructural changes were observed under an electron microscope. Results The blood pressure of sham operation group was decreased a little with time extension, but within normal limits. The mean arterial pressure (MAP) of model group and Xuebijing treated group developed into a state of sepsis shock at 9 hours and 10 hours after operation respectively, and MAP were lower than 70 mmHg (1 mmHg=0.133 kPa). The MAP levels of model and Xuebijing groups at 11 hours after operation were lower significantly than those of sham operation group (mmHg:58.7±7.0, 58.7±8.3 vs. 91.0±8.2, both P<0.01), and they were persistently decreased at 12 hours after operation;the MAP in Xuebijing group was a little higher than that of model group at the same period (mmHg:55.4±4.0 vs. 48.8±12.9, P>0.05). The results of the observation with electron microscope:the structures of heart, lung, liver and kidney in sham operation group were basically normal;all the organs of model group appeared different degrees of structural damage. Compared with model group, the injury of heart and lung in Xuebijing treated group was milder, especially, the changes of cellular mitochondria were obvious;however, there was no significant difference in injury of kidney and liver between the model and Xuebijing treated groups. Conclusion Xuebijing injection can play a certain role in stabilizing the circulatory system in rats with septic shock, and can possibly ameliorate the heart and lung damage caused by infection and shock.

Objective:To investigate and analyze the current status of patient satisfaction and the influencing factors at private hospitals in Guizhou Province,and thus to provide a scientific basis for the management of medical service at private hospitals.Methods:The satisfaction scores were statistically described and analyzed by the factor analysis and multiple linear regression analysis.Results:The overall satisfaction score of patients was (3.87 ± 0.85),of which the satisfaction of medical technology,drug price,inspection fee,and medical facilities was lower.The factor analysis showed that satisfaction of patients at private hospitals could be classified into the environment,the quality of service,medical expense,and service flow.Multivariate linear regression results showed that its standardized partial regression coefficient by the parameter descending order followed as medical expense,the environment,the quality of service,and then service flow.Conclusions:Private hospitals should set up a fair medical expenditure mechanism,improve the environment and quality of medical services,and optimize service flow in order to improve patient satisfaction.

Objective To investigate the effect of 23.4% hypertonic saline(HTS)on intracranial pressure(ICP), cerebral peffusion pressure(CPP), cerebral blood flow(CBF)in poor-grade patients with subarachnoid hemorrhage(SAH).Methods Sixteen patients(Glasgow coma score ≤ 8)with poor-grade SAH received 23.4% hypertonic saline intravenously for elevated ICP.ICP, mean arterial pressure(MAP), CPP and the middle cerebral artery flow velocity(FV)were observed and recorded before and at 30, 60, 90,120, 150, 180 min after the injection respectively.Results Thirty minutes postinfusion, a significant increase in MAP, CPP, FV was seen together with a decrease in ICP(P<0.05).ICP remained reduced for 180 minutes, CPP and FV remained elevated for 90 minutes(P < 0.05).Conclusions HTS can significantly decrease ICP and improve CBF in patients with poor-grade subarachnoid hemorrhage and may be used for reversal of pathophysiologic changes caused by cerebral ischemia.

AIM:To check the physical interaction between GST-Na+-K+-ATPase domain and recombinant human augmenter of liver regeneration (rhALR) by GST pull down assay. METHODS: With PCR and genetic recombinant techniques, the coding region of ? subunit of Na+-K+-ATPase was cloned into expressing plasmid pGEX-4T and identified by endonuclease digestion and sequencing methods. Under the inducing of 0.1 mmol/L IPTG, the fusion protein GST-Na+-K+-ATPase domain was highly expressed by E.coli DH-5?. After hypersound quassating, the GST-Na+-K+-ATPase domain was purified by glutathione agarose beads and the physical interaction with rhALR was checked by GST pull down assay. RESULTS: Analysis by SDS-PAGE showed the rhALRs of monomer and dimmer in GST-Na+-K+-ATPase domain lane. The Western blotting of the GST-pull down assay showed the same results as well. CONCLUSION: The Na+-K+-ATPase domain is associated with rhALR specifically in vitro.

Objective: To investigate the factors affecting drug-induced liver injury among patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019, so as to provide insights into the prevention of drug-induced liver injury. Methods: Demographic features, presence of drug-induced liver injury, and disease history prior to anti-tuberculosis therapy were captured from patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019 through the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System and Ningbo Regional Diagnosis and Treatment Information Platform. Factors affecting drug-induced liver injury was identified using the multivariable logistic regression analysis. Results: A total of 9 397 patients with pulmonary tuberculosis were enrolled, among whom 66.43% ( 6 242 case ) were male, 65.89% ( 6 192 cases ) were at ages of <60 years, and 92.35% ( 8 678 cases ) were treatment-naïve. There were 1 425 patients with drug-induced liver injury (15.16% incidence), including 729 cases with grade 1 (51.16%), 24 cases with grade 2 (1.68%), 7 cases with grade 3 (0.49%), 7 cases with grade 4 ( 0.49% ), and 658 cases with ungraded drug-induced liver injury ( 46.18% ). The median duration between drug administration and development of drug-induced liver injury was 24 ( interquartile range, 44 ) days. Multivariable logistic regression analysis identified treatment-naïve ( OR=1.464, 95%CI: 1.153-1.859 ) and history of liver disease ( OR=2.001, 95%CI: 1.709-2.342) as risk factors for drug-induced liver injury in patients with pulmonary tuberculosis. Conclusion The incidence of drug-induced liver injury was 15.16% among pulmonary tuberculosis patients in Ningbo City from 2015 to 2019. Treatment-naïve and a history of liver disease are associated with drug-induced liver injury among patients with pulmonary tuberculosis.
