Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Objective:To investigate the association between baseline hemoglobin level and early neurologic deterioration(END)after intravenous thrombolysis in patients with acute ischemic stroke(AIS).Methods:Data of AIS patients who received intravenous thrombolytic therapy at multiple hospitals across the country between January 2017 and July 2020 were collected from the online database Acute Stroke Patients for Stroke Management Quality Evaluation(CASE-Ⅱ,NCT04487340).Binary logistic regression analysis was used to study the factors affecting the occurrence of END after intravenous thrombolytic therapy,and the correlation between baseline hemoglobin level and END was investigated by limiting cubic spline curve analysis.Results:A total of 8162 patients were included.Patients with END had lower baseline hemoglobin levels(136 and 140 g/L,P<0.01)and higher rates of anemia(24.2%and 16.9%,P<0.01)compared with non-END patients.Binary logistic regression analysis showed that baseline hemoglobin level(OR=0.995,95%CI:0.991-0.999,P<0.05)and anemia(OR=1.238,95%CI:1.055-1.454,P<0.01)were independently correlated with the occurrence of END after intravenous thrombolysis in AIS patients.Restricted cubic spline regression showed that there was a U-shaped relationship between hemoglobin level and the risk of END after intravenous thrombolysis in AIS patients(P<0.01),although this relationship was only significant in male patients(P<0.05)and not in female patients(P>0.05).Conclusion:There is a correlation between baseline hemoglobin level and the risk of END in AIS patients after intravenous thrombolysis,especially in male patients,in whom both lower and higher hemoglobin level may increase the risk of END.

Esophageal squamous cell carcinoma (ESCC) is one of the leading causes of cancer death worldwide. It is urgent to develop new drugs to improve the prognosis of ESCC patients. Here, we found benzydamine, a locally acting non-steroidal anti-inflammatory drug, had potent cytotoxic effect on ESCC cells. Benzydamine could suppress ESCC proliferation in vivo and in vitro. In terms of mechanism, CDK2 was identified as a target of benzydamine by molecular docking, pull-down assay and in vitro kinase assay. Specifically, benzydamine inhibited the growth of ESCC cells by inhibiting CDK2 activity and affecting downstream phosphorylation of MCM2, c-Myc and Rb, resulting in cell cycle arrest. Our study illustrates that benzydamine inhibits the growth of ESCC cells by downregulating the CDK2 pathway.

BACKGROUND:Slow growth of peripheral nerve, muscle denervation atrophy and fossilization of motor end plate fol owing sciatic nerve injury cause irreversible limb function disorders. Umbilical cord mesenchymal stem cells have been widely used in multi-disciplinary research, but studies concerning umbilical cord mesenchymal stem cells delaying denervated muscle atrophy in rats fol owing peripheral nerve injury are rarely reported.
OBJECTIVE:To observe the value of human umbilical cord mesenchymal stem cells transplantation to delay denervated muscle atrophy of rats after sciatic nerve injury.
METHODS:Umbilical cord blood was col ected from healthy parturient woman after ful-term delivery. In the experimental group, the rat’s Sunderland IV degree sciatic nerve injury model was established by 5 mm denervation, epineurial repair, and 5 mm smal gap transplantation of umbilical cord mesenchymal stem cells. In the control group, after modeling, the same volume of normal saline was injected into the smal gap. The main outcome measures included the sciatic nerve function index, the wet weight of triceps surae,sciatic nerve latency, action potential conduction velocity and amplitude,and skeletal muscle fiber cross section area maintenance rate.
RESULTS AND CONCLUSION:After 4, 8 and 12 weeks of modeling, the sciatic nerve function index values, the wet weight of triceps surae and skeletal muscle fiber cross section area maintenance rates in the experimental group were significantly higher than those in the control group (P<0.05). After 12 weeks of modeling, electromyography results showed sciatic nerve latency was significantly lower, but action potential conduction velocity and amplitude were dramatical y higher in the experimental group than the control group (P<0.05, P<0.001). Human umbilical cord mesenchymal stem cells transplantation in denervated muscle atrophy rats after sciatic nerve promotes nerve growth, delays denervated muscle atrophy, maintains the denervatied neuromusle’s morphology and function.
