Objective To analyze the application effect and safety of streamlined liner of the pharynx airway (SLIPA) anesthesia in painless fiberoptic bronchoscopy (FB).Methods Two hundred and eighty-two patients who undorwent FB examination in Kaifeng Second People's Hospital from January 2015 to January 2017 were selected and divided into observation group and control group,with 141 patients in each group.The patients in observation group were given SLIPA assisted anesthesia;the patients in control group were given endoscopic mask assisted anesthesia.The oxygen saturation (SpO2),systolic blood pressure (SBP),diastolic pressure (DBP) and heart rate (HR) of patients in the two groups were monitored.The changes of SBP,DBP and HR,the incidence of adverse reactions and the satisfaction of patient to the anesthesia were compared between the two groups.Results The fluctuation of HR,SBP and DBP of patients in the observation group was (3.52 ± 2.92) times · min-1,(7.04 ±5.30) mmHg(1 mmHg =0.133 kPa),(1.52 ± 1.63) mmHg respectively and in the control group was (5.52 ± 1.89) times · min-1,(30.12 ± 8.88) mmHg,(4.06 ± 5.78) mmHg respectively;the fluctuations of HR,SBP and DBP of patients in the observation group were significantly less than those in the control group(P ＜ 0.05).In the observation group,12 patients with cough,8 patients with abdominal distension,6 patients with pharyngeal pain,2 patients with SpO2 ≤90％,4 patients with SpO2 ＜ 85％;in the control group,57 patients with cough,32 patients with abdominal distension,47 patients with pharyngeal pain,28 patients with SpO2 ≤90％,19 patients with SpO2 ＜ 85％.The incidence of adverse reactions of patients in the observation group was significantly lower than that in the control group (x2 =27.10,61.82,41.59,72.46,87.75;P ＜0.05).The anesthesia satisfaction of patients in the observation group(97.87％) was significantly higher than that in the control group(82.98％) (x2 =29.97,P ＜ 0.05).Conclusion SLIPA assisted anesthesia has good clinical effect and safety in patients with painless FB.

Objective: To investigate the mechanism of liver and lung injury in mouse septic models. [Methods: Twenty-four male Kunming mice were subjected to cecal ligation and puncture (CLP) or sham operation. The permeability of microvasculature, water contents, activities of myeloperoxidase (MPO) and the apoptosis of microvascular endothelial cells in lung microvasculature and liver sinus were examined 3 h and 12 h after operation. Results: Both the liver and lung showed a significant increase in microvessel permeability at 12 h in CLP group compared with sham operation group. MPO activity and water content in CLP group were obviously higher than those in the sham operation group. The apoptosis of lung microvascular endothelial cells at 12 h in CLP group (5.03 ± 0.92)% was significantly higher than that of control group (3.48 ± 1.21)% (P< 0.01). Conclusion: Sepsis can lead to severe injury to the liver and lung. Apoptosis in lung microvascular endothelial cells might cause alteration of microvascular permeability, finally resulting in the injury of lung.

Objective To investigate the expression of procalcitonin (PCT) and C-reactive protein (CRP),and endotoxin in bloodstream infection with different microorganisms,so as to assess the value of these inflammatory cytokines in early diagnosis of sepsis in bloodstream infections patients.Methods Data of 152 septic bloodstream infected patients with 90 male and 62 female aged from 62 to 102 years and 79.2 ± 16.3 years in average admitted from January 2012 to December 2013 were analyzed retrospectively.According to the results of blood culture,the microorganisms could be categorized into gram-negative bacteria,gram-positive bacteria and fungus groups,and the levels of serum CRP,PCT,and endotoxin were compared among these groups of bloodstream infections patients within 24 hours after admission.Results (1) A total of 152 strains of microorganisms were surveyed including 92 gram-negative strains (61.18％),43 gram-positive strains (28.29％),and 16 fungal strains (10.53％).In the gram-negative strains,Klebsiella pneumoniae (n =29),Acinetobacter baumannii (n =24),Escherichia coli (n =23),Burkholderia cepacia (n =9) and Pseudomonas aeruginosa (n =4) were the most common isolates.In the Gram-positive strains,13 strains of Staphylococcus aureus were isolated.(2) In the gram-negative bacterial bloodstream infections group,there were 60 (64.52％) patients with endotoxin positive,and there were no endotoxin positive cases with detected gram-positive bacteria and fungal bloodstream infections.The median levels of PCT were significantly different among the three groups [gram-negative strains group:7.760 (3.365,28.585) ng/mL,gram-positive strains group:0.705 (0.265,3.225) ng/mL,fungal infection group:1.245 (0.543,1.998) ng/mL].In the fungal bloodstream infection group,the mean level of CRP was higher than that in other two groups [gram-negative strains group:(126.01 ± 66.53) mg/L,gram-positive strains group:(77.58 ±54.21) mg/L,fungal infection group:(140.14 ±71.21) mg/L].(3) The receiver operating characteristic (ROC) curve of inflammatory cytokines was made for the diagnostic value in bloodstream infections.ROC curve used to distinguish between gram-positive bacterial bloodstream infections group and fungal group showed that AUCPCT+CRP =0.791.When PCT cut-off value was 0.92 ng/mL,and CRP cut-off value was 68.00 mg/L,the sensitivity was 50％ and the specificity was 95.5％.ROC curve used to distinguish between the gram-negative bacterial bloodstream infections group and fungal group showed that AUCPCT+CRP+LPS =0.947.When PCT cut-off value was 2.16 ng/mL and CRP cutoff value was 94.10 mg/L,and endotoxin was positive,the sensitivity was 82.8％ and the specificity was 100％.ROC curve used to distinguish between gram-negative bacterial bloodstream infections group and gram-positive bacterial group showed that AUCPCT+CRP+LPS =0.947.When PCT cut-off value was 2.68 ng/ mL,CRP cut-off value was 106.5 mg/L,endotoxin was positive,the sensitivity was 74.2％ and the specificity was 97.7％.Conclusions Gram-negative bacteria were the most common microorganisms in bloodstream infections in ICU patients.Compared with single inflammatory cytokine,the serum concentrations of PCT,CRP and endotoxin used together could provide more sensitivity and specificity for the early diagnosis of bloodstream infection with different microorganisms.

Objective:To investigate the value of anti-hexokinase1 antibodies (anti-HK-1) and anti-kelch-like 1 antibodies (anti-KLHL12) antibody in evaluating ursodeoxycholic acid (UDCA) response in patients with primary biliary cholangitis (PBC).Methods:112 PBC patients who had been treated with UDCA for more than 12 months with relatively complete clinical data were analyzed. Serum was collected and the expression of anti-mitochondrial antibody (AMA), anti-HK-1 and anti-KLHL12 antibodies were detected by ELISA. The response to UDCA was based on Paris standard. According to the expression of new antibodies, the patients were divided into the new antibody positive group and negative group. In addition, PBC related baseline indicators were collected, and Spearman correlation analysis was used to study the correlation between antibody expression and baseline indicators in PBC patients.Results:Positivity of anti-HK1 and anti-KLHL12 antibody in AMA-positive PBC patients were 44.7% and 41.2% respectively. Positivity of anti-HK1 and anti-KLHL12 antibodies in AMA negative PBC patients were 33.3% and 22.2%. Anti-HK1 positive patients had higher serum levels of Alaninetransaminase (ALP), aspartate aminotransferase, (AST), γ-glutamyl transpeptidase (γ-GT) and total bilirubin (TBIL) compared with anti-HK1 negative patients, with statistical significant differences ( P<0.05). Notably, correlation analysis showed significantly positive correlation between anti-HK1 antibody expression and ALP, γ-GT and TBIL serum levels ( r=0.735, P<0.05; r=0.332, P<0.05; r=0.491, ( r=0.466, P<0.05). The UDCA response rate in anti-HK-1 antibody positive group was lower than that of the negative group (36.2% vs 60%; P<0.05). Conclusion:Anti-HK-1 and anti-KLHL12 antibody can help to diagnose PBC, and the expression of anti-HK-1 antibody is correlated with the severity of PBC, which could help to predict the reaction of PBC patients to UDCA.
