Objective：To investigate the effect of comprehensive pulmonary rehabilitation therapy on pulmonary and motor function in children after pneumonia. Method：Children with improved acute symptoms of community-acquired pneumonia who were hospitalized in PKUFH-Ningxia Women and Children's Hospital from September 2020 to January 2021 were selected and divided into experimental group (n=30) and control group (n=30) according to the treatment intention of patients and parents. Comprehensive pulmonary rehabilitation therapy was provided to the patients in the experimental group. The pulmonary function and motor function of the two groups were assessed prior to intervention and 3 months after intervention. The forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and the ratio of forced expiratory volume in one second to forced vital capacity (FEV1/FVC), Borg scores and 6min walking test (6MWT) results were recorded and statistically analyzed. Result：After intervention, FEV1/FVC in experimental group was significantly higher than control group (P＜ 0.05); the FVC, FEV1 and 6MWT of the experimental group were significantly higher than those before intervention (P＜0.05). There were significant differences in FVC, FEV1, Borg scores and 6MWT between the experimental group and the control group before and after intervention (P＜0.05). Conclusion：Comprehensive pulmonary rehabilitation therapy is helpful to the recovery of pulmonary and motor function in children after community-acquired pneumonia. [ABSTRACT FROM AUTHOR]

Sepsis is a life-threatening organ dysfunction caused by the imbalance of host immune response to infection, which immune regulation mechanism is complex and has not been clarified. Programmed death receptor-1 （PD-1）/programmed death receptor ligand-1 （PD-L1） is a negative co-inhibitory molecule that has attracted much attention in recent years. Studies have shown that PD-1/PD-L1 signaling pathway plays an important immunosuppressive role in sepsis. There are differences in immune regulation mechanisms in heart, liver, spleen, lung and kidney, which has not been clarified. Immune regulation of PD-1/PD-L1 in different organs of sepsis is reviewied in this article, which could to provide a new direction for the study of sepsis. [ABSTRACT FROM AUTHOR]

In order to solve the problem of clutch slip caused by excessive pressure loss of rotary joint seal in marine field, a mechanical seal with V-shaped groove in end face which can reduce the pressure loss was proposed. This proposed seal can enhance the sealing performance of rotary joint, ensure the normal operation of rotary joint, and reduce the rotating machinery failure caused by the failure of rotary joint seal. In this research, the numerical model of the flow field of the rotary joint mechanical seal was firstly constructed, and then the accuracy of the model was verified by the pressure loss test bench of the rotary joint. Finally, the V-shaped groove type, micro-pit type and arc-shaped groove type of the rotary joint mechanical seal proposed in this research were compared and analyzed. The results show that compared with the original grooveless rotary joint mechanical seal, the pressure loss of the V-shaped groove type rotary joint mechanical seal can be reduced by about 10 %, the pressure loss of the micro-pit type rotary joint mechanical seal can be increased by about 4 %, and the pressure loss of the arc-shaped groove type rotary joint mechanical seal can be increased by about 21%.

Redox-sensitive cysteine (RSC) thiol plays an important role in many biological processes such as photosynthesis, cellular metabolism, and transcription. Therefore, it is necessary to identify redox-sensitive cysteine accurately. However, traditional redox-sensitive cysteine identification is very expensive and time-consuming. At present, there is an urgent need for a mathematical calculation method to identify sequence information and redox-sensitive cysteines quickly and accurately. Here, we developed an effective predictor called iRSC-PseAAC, which used the dimension reduction algorithm LDA combined with the support vector machine to predict redox-sensitive cysteine sites. In the cross-validation results, the specificity (Sp), sensitivity (Sn), accuracy (Acc) and Matthews correlation coefficient (MCC) were 0.841, 0.868, 0.859 and 0.692 respectively. In the independent dataset results, the Sp, Sn, Acc and MCC were 0.906, 0.882, 0.890 and 0.767 respectively. compared with existing prediction methods, iRSC-PseAAC had obvious improvement effect. The method proposed for this study can also be used for many problems in computational proteomics. [ABSTRACT FROM AUTHOR]

Tannery meat residue solid waste is a kind of protein-rich waste, which is easy to corrupt and stink and pollute the environment for a long time. Therefore, how to develop its value is a problem that tannery enterprises pay more attention to. In this study, the solid waste of tannery meat residue was pre‐ pared into meat residue hydrolysate by biological enzyme method. The preparation process of meat resi‐ due hydrolysate dry powder was determined by experiments. The inlet temperature was set at 140 ℃ and the flow rate was 17 r/min. The meat residue hydrolysate dry powder can obtain the maximum yield. This dry powder was used as a nitrogen source for the fermentation production of JW-3 dehairing enzyme. On the basis of single factor experiment, the response surface analysis method was used to screen out the best addition ratio of dry powder of meat residue hydrolysate and optimize the culture medium. The re‐ sults showed that the optimal medium for the enzyme production of the genetically engineered strain WB800N/pHT43-npr was as follows: dextrin 30 g/L, dry powder of meat residue hydrolysate 20 g/L, MnSO4 26 mg/L, CaCl2 0.05 g/L. The protease fermentation activity was 1 203.5 U/mL, which was about 10% higher than that of the basic fermentation medium. This opens up a new way for the resource utiliza‐ tion of tannery meat residue solid waste. [ABSTRACT FROM AUTHOR]

Objective To investigate the difference of electrocardiographic (ECG) features between total left main artery (LM) occlusion and subtotal occlusion, and analyze risk factors of in-hospital mortality. Methods A total of 94 patients with left main complete occlusion and 99 patients with subtotal occlusion were included. ECG characteristics, coronary angiography and other clinical data were compared, and factors of hospital death were analyzed. The receiver operating characteristics (ROC) curve was used to analyze the predictive value of ECG characteristics in hospital death risk in patients with LM occlusion. The relationship between ECG characteristics, shock and collateral circulation were analyzed in patients with LM occlusion. Results Compared with the subtotal occlusion group, patients with LM occlusion presented with more ST-segment elevation (STE) in Ⅰ, avL, V2-V5, more STE in avR and avL, more left anterior fascicular block + right bundle branch block, prolonged QRS duration, less STE in avR and less STE in avR+V1.The in-hospital mortality was 46.8% (44/94) in LM occlusion and 14.1% (14/99) in LM subtotal occlusion. STE in avR+avL predicted total LM occlusion with a specificity of 0.97, and left anterior branch + right bundle branch block predicted total LM occlusion with a specificity of 1.00. In patients with total LM occlusion, STE in Ⅰ, avL, V2-V5, prolongation of QRS duration, shock, no collateral circulation, STE in Ⅰ, avL, V2-V5 combined with left anterior fascicular block + right bundle branch block, and STE in Ⅰ, avL, V2-V5 combined with shock predicted in-hospital mortality, with the area under the curve of 0.716, 0.619, 0.766, 0.688, 0.572, 0.785, respectively. The diagnostic specificity of STE in Ⅰ, avL, V2-V5 combined with shock was 0.82, and the sensitivity was 0.75. STE in Ⅰ, avL, V2-V5 combined with left anterior fascicular block+right bundle branch block predicted in-hospital death in LM occlusion with a specificity of 0.94. The proportion of shock was higher in patients with STE in Ⅰ, avL, V2-V5, left anterior fascicular block+right bundle branch block and collateral flow absence (P＜0.05). In patients with total occlusion, no collateral flow was observed in patients with STE in Ⅰ, avL, V2-V5. In patients with STE in avR (including avR+V1), 82.4% of patients presented with right coronary collateral circulation supplying the left anterior descending coronary artery and left circumflex artery territory. In patients with STE in avR+avL, 69.2% of patients presented with right coronary collateral circulation supplying left anterior descending coronary artery territory. Conclusion Total LM occlusion presents with different ECG features compared with subtotal occlusion. In LM total occlusion, the ECG features predict in-hospital mortality and are associated with different collateral circulation. [ABSTRACT FROM AUTHOR]
