Objective: To identify the risk factors in mortality of pediatric acute respiratory distress syndrome (PARDS) in pediatric intensive care unit (PICU). Methods: Second analysis of the data collected in the "efficacy of pulmonary surfactant (PS) in the treatment of children with moderate to severe PARDS" program. Retrospective case summary of the risk factors of mortality of children with moderate to severe PARDS who admitted in 14 participating tertiary PICU between December 2016 to December 2021. Differences in general condition, underlying diseases, oxygenation index, and mechanical ventilation were compared after the group was divided by survival at PICU discharge. When comparing between groups, the Mann-Whitney U test was used for measurement data, and the chi-square test was used for counting data. Receiver Operating Characteristic (ROC) curves were used to assess the accuracy of oxygen index (OI) in predicting mortality. Multivariate Logistic regression analysis was used to identify the risk factors for mortality. Results: Among 101 children with moderate to severe PARDS, 63 (62.4%) were males, 38 (37.6%) were females, aged (12±8) months. There were 23 cases in the non-survival group and 78 cases in the survival group. The combined rates of underlying diseases (52.2% (12/23) vs. 29.5% (23/78), χ2=4.04, P=0.045) and immune deficiency (30.4% (7/23) vs. 11.5% (9/78), χ2=4.76, P=0.029) in non-survival patients were significantly higher than those in survival patients, while the use of pulmonary surfactant (PS) was significantly lower (8.7% (2/23) vs. 41.0% (32/78), χ2=8.31, P=0.004). No significant differences existed in age, sex, pediatric critical illness score, etiology of PARDS, mechanical ventilation mode and fluid balance within 72 h (all P>0.05). OI on the first day (11.9(8.3, 17.1) vs.15.5(11.7, 23.0)), the second day (10.1(7.6, 16.6) vs.14.8(9.3, 26.2)) and the third day (9.2(6.6, 16.6) vs. 16.7(11.2, 31.4)) after PARDS identified were all higher in non-survival group compared to survival group (Z=-2.70, -2.52, -3.79 respectively, all P<0.05), and the improvement of OI in non-survival group was worse (0.03(-0.32, 0.31) vs. 0.32(-0.02, 0.56), Z=-2.49, P=0.013). ROC curve analysis showed that the OI on the thind day was more appropriate in predicting in-hospital mortality (area under the curve= 0.76, standard error 0.05,95%CI 0.65-0.87,P<0.001). When OI was set at 11.1, the sensitivity was 78.3% (95%CI 58.1%-90.3%), and the specificity was 60.3% (95%CI 49.2%-70.4%). Multivariate Logistic regression analysis showed that after adjusting for age, sex, pediatric critical illness score and fluid load within 72 h, no use of PS (OR=11.26, 95%CI 2.19-57.95, P=0.004), OI value on the third day (OR=7.93, 95%CI 1.51-41.69, P=0.014), and companied with immunodeficiency (OR=4.72, 95%CI 1.17-19.02, P=0.029) were independent risk factors for mortality in children with PARDS. Conclusions: The mortality of patients with moderate to severe PARDS is high, and immunodeficiency, no use of PS and OI on the third day after PARDS identified are the independent risk factors related to mortality. The OI on the third day after PARDS identified could be used to predict mortality.

OBJECTIVE:
To identify the key outcome indexes in treatment of migraine with acupuncture and moxibustion.
METHODS:
Using literature research, questionnaire survey and consensus conference, the key outcome indexes in treatment of migraine with acupuncture and moxibustion were screened and prioritized.
RESULTS:
The critical outcome indexes for the treatment in attack stage of migraine included 6 effectiveness outcome indexes (headache intensity, headache duration, headache relieve time, effectiveness and level of headache relief within 2 h, headache-related quality of life, level of headache relief within 24 h) and 1 safety outcome index (incidence of serious adverse reactions). The critical outcome indexes for prophylactic treatment included 6 effectiveness outcome indexes (headache day, headache frequency, headache intensity, effective rate, headache-related quality of life, health-related quality of life) and 1 safety outcome index (incidence of serious adverse reactions).
CONCLUSION
In terms of the attack stage treatment and prophylactic treatment with acupuncture and moxibustion, the outcome indexes are different, among which, those can directly reflect the conditions of migraine should be optioned in priority. To assess the effectiveness of attack stage, the headache intensity is preferred, using the visual analogue scale (VAS) score, and the preferred time is 2 hours after treatment. Regarding the effectiveness of prophylactic treatment, the headache day, headache frequency and headache intensity should be firstly considered in the assessment, in which, the preferred time for assessment is 12 weeks into treatment, while, the best time for follow-up should be 12 weeks after treatment completion. When the quality of life is considered, the migraine-specific quality of life questionnaire (MSQ) is the top option. For either the attack stage treatment or the prophylactic treatment, the high attention should be laid on the outcome indexes for safety and medical economics evaluation.

OBJECTIVETo study the inhibitory effect of paeoniflorin (PAE) on TNF-α-induced TNF receptor type I (TNFR1)-mediated signaling pathway in mouse renal arterial endothelial cells (AECs) and to explore its underlying molecular mechanisms.
METHODSMouse AECs were cultured in vitro and then they were treated by different concentrations PAE or TNF-α for various time periods. Expression levels of intercellular cell adhesion molecule-1 (ICAM-1) were detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 6-h TNF-α 30 ng/mL), the low dose PAE group (cultured by 2-h PAE 0.8 μmo/L plus 6-h TNF-α 30 ng/mL), the middle dose PAE group (cultured by 2-h PAE 8 μmol/L plus 6-h TNF-α 30 ng/mL), the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 6-h TNF-α 30 ng/mL) with Western blot analysis. Nuclear translocation of transcription factor NF-κB (NE-κB) was detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 45-mm TNF-α 30 ng/mL), and the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 45-min TNF-α 30 ng/mL) by immunofluorescent staining. Expression levels of the phosphorylation of extracellular signal-regulated (protein) kinase (ph-ERK) and p38 (ph- p38) were detected in the normal group (cultured by serum-free culture media) and the high dose PAE group (2-h PAE 80 μmol/L culture) by Western blot. NF-κB inhibitor-α (IκBα) protein expressions were detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 30-min TNF-α 30 ng/mL), the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 30-min TNF-α 30 ng/mL), the p38 inhibitor group (SB group, pretreatment with SB238025 25 μmol/L for 30 min, then treated by PAE 80 μmol/L for 2 h, and finally treated by TNF-α 30 ng/mL for 30 min), the ERK inhibitor group (PD group, treated by PD98059 50 μmol/L for 30 min, then treated by PAE 80 μmol/L for 2 h, and finally treated by TNF-α 30 ng/mL for 30 min) by Western blot.
RESULTSCompared with the normal group, ICAM-1 protein expression levels obviously increased (P < 0.01). Compared with the TNFα group, ICAM-1 protein expression levels were obviously inhibited in the high dose PAE group (P < 0.05). Protein expression levels of ph-p38 and ph-ERK were obviously higher in the hIgh dose PAE group (P < 0.05). Compared with the normal group, IκBα protein expression levels obviously decreased in the TNF-α group (P < 0.01). Compared with the TNFα group, TNF-α-induced IκBα degradation could be significantly inhibited in the high dose PAE group (P < 0.01); the inhibition of PAE on IκBα degradation could be significantly inhibited in the SB group (P < 0.05). NF-κB/p65 signal was mainly located in cytoplasm in the normal group. NF-κB/p65 was translocated from cytoplasm to nucleus after stimulated by 45 min TNF-α in the TNF-α group, while it could be significantly inhibited in the high dose PAE group.
CONCLUSIONSPAE inhibited TNF-α-induced expression of lCAM-1. Its action might be associated with inhibiting TNFR1/NF-κB signaling pathway. p38 participated and mediated these actions.

Objective To observe the relationship between serum uric acid and brachial ankle pulse wave velocity (ba-PWV) in Beijing community individuals.Methods This epidemiological survey was performed in residents of two communities from Shijingshan District in Beijing from 2007 to 2008.Cardiovascular risk factors and ba-PWV were measured. Two thousand five hundred and forty three individuals with both ba-PWV and serum uric acid measurements were included.Ba-PWV ≥ 1400 cm/s was defined as abnormal.The individuals were divided into four groups (Q1,Q2,Q3 and Q4 group) according to the gender-specific quartiles of serum uric acid. Univariate logistic regression was used to evaluate the relation between various cardiovascular risk factors and ba-PWV abnormality.Multivariate logistic regression was used to evaluate the relation between serum uric acid and ba-PWV abnormality after adjusting for other cardiovascular risk factors.Results Body mass index,triglyeride and prevalence of hypertension increased with increasing levels of serum uric acid (all P <0.01 ).Univariate logistic regression analysis showed that age,gender,smoking,hypertension,systolic blood pressure,diastolic blood pressure,diabetes,body mass index,total cholesterol,triglyeride and estimated glomerular filtration rate were related with ba-PWV abnormality( all P <0.01 ).Compared with Q1 group,ba-PWV abnormality OR value of Q4 group was 1.73 (95% CI:1.34- 2.22,P <0.01 ).Multivariate logistic regression revealed that ba-PWV abnomality OR value of Q4 group was 1.66 (95% CI:1.16 -2.37,P<0.01 ) after adjusting for age,gender,smoking,hypertension,systolic blood pressure,diastolic blood pressure,diabetes,body mass index,total cholesterol,triglyeride and estimated glomerular filtration rate when compared with Q1 group and OR values were 1.55 (95% CI:0.88 -2.74,P>0.05) and 1.65 (95% CI:1.04-2.64,P<0.05) in male and female respectively.Conclusion Increased serum uric acid was independently associated with ba-PWV abnormality in Beijing community residents.

Objective To investigate the specific roles of gap junction and ATP in mechanical stimulation induced calcium transfer in osteoblasts. Methods The isolated osteoblastic pattern without gap junctions was established by using the micropatterning method. Then fluid shear stress was applied on cells using the flow chamber to observe and analyze the characteristic parameters of calcium response. Results Multiple calcium response still occurred in osteoblastic pattern without gap junction, but the response time to the first responsive peak was much longer than that with gap junction. When the intracellular and extracellular calcium ions were removed, only 40% cells responded to the mechanical stimulation, with single peak and multiple peaks accounting for 50%, respectively. If ATP pathway was blocked, only 20% cells responded, most of which showed single peak. Conclusions ATP was the major pathway mediating intercellular calcium transfer, while the gap junction was not the necessary one.

OBJECTIVETo identify zebrafish mutants with myelopoiesis defects by ENU mutagenesis and large-scale forward genetic screening.
METHODSMale zebrafish were mutagenized with N-ethyl N-nitrosourea to induce mutations in the spermatogonial cells to generate the founders, which were outcrossed with AB to raise F1 fish. The F1 fish from different founders were mated to generate the F2 families. The F3 embryos from F2 sibling crosses were screened by Sudan black B staining and neutral red staining.
RESULTSA total of 350 F2 families from F1 sibling crosses were screened, and 1424 F2 crosses were analyzed. Six mutations were identified resulting in abnormal Sudan black B staining and neutral red staining, indicating the involvement of neutrophil deficiency or macrophage abnormalities.
CONCLUSIONIt is simple and cheap to induce and screen myelopoiesis deficiency in zebrafish by ENU chemical mutagenesis and Sudan black B staining and neutral red staining. These mutants shed light on the identification of the genes important to myelopoiesis in zebrafish.
