Objective To analyze the application of flipped classroom in the practical teaching of rehabilitation assessment courses for rehabilitation therapy majors,and to explore a new teaching method for rehabilitation therapy.Methods Eighty students majoring in rehabilitation therapy from the Department of Rehabilitation Medicine of Guangzhou Xinhua University in grade 2020 were selected as the research objects.They were assigned into observation group or control group according to the random number table method,with 40 cases in each group.The observation group adopted the flip classroom teaching mode,and the rehabilitation assessment course teaching based on flipped classroom was carried out,while the control group adopted the traditional teaching mode.The students'theoretical and operational assessment results,teaching effect,and teaching model satisfaction were analyzed.Results No statistically significant differences were found in theoretical test scores between the two student groups(by gender/course).The students in the observation group had higher theoretical scores[(80.25±11.65 vs 72.50±14.28)score].The observation group showed significantly higher satisfaction scores than the control group across all three dimensions:classroom learning enthusiasm,teacher-student interaction,and overall teaching satisfaction.(P<0.05).Conclusion The application of flipped classroom in the rehabilitation therapy teaching is helpful to improve the professional theoretical level of students,and to a certain extent,it is beneficial to improve the professional level of teachers.

Sepsis is a complex syndrome caused by multiple pathogens and involves multiple organ failure, particularly spleen dysfunction. In 2017, the worldwide incidence was 48.9 million sepsis cases and 11 million sepsis-related deaths were reported (Rudd et al., 2020). Inflammation, oxidative stress, and apoptosis are the most common pathologies seen in sepsis. Liensinine (LIE) is a bisbenzylisoquinoline-type alkaloid extracted from the seed embryo of Nelumbo nucifera. Lotus seed hearts have high content of LIE which mainly has antihypertensive and antiarrhythmic pharmacological effects. It can exert anti-carcinogenic activity by regulating cell, inflammation, and apoptosis signaling pathways (Manogaran et al., 2019). However, its protective effect from sepsis-induced spleen damage is unknown. In this research, we established a mouse sepsis model induced by lipopolysaccharide (LPS) and investigated the protective effects of LIE on sepsis spleen injury in terms of inflammatory response, oxidative stress, and apoptosis.

Objective:To explore the effect of taxifolin on H2O2-induced pyroptosis in H9C2 cells and the possible mechanisms.Methods:The H9C2 cells was divided into 3 groups:a control group,a hydrogen peroxide (H2O2) group and a taxifolin group.The morphology of H9C2 cells was observed by inverted phase contrast microscope.The mitochondrial membrane potential was measured by JC-1 staining and flow cytometry.The alteration of the level of reactive oxygen species (ROS) was detected by specific mitochondrial probe.The protein levels of cysteinyl aspartate specific proteinase-1 (caspase-1) was determined by Western blot.The mRNA levels of interleukin-18 (IL-18),interleukin-1a (IL-1a),interleukin-1b (IL-1b),absent in melanoma 2 (AIM2),apoptosis-associated apeck-like protein (ASC),nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3)and nucleotide-binding oligomerization domain-like receptor family caspase recruitment domaincontaining protein 4 (NLRC4) were determined by reverse transcription-polymerase chain reaction (RT-PCR).Results:Compared with the control group,the morphology of H9C2 cells obviously changed in the H2O2-treated group,which was guadually improved in the presence of taxifolin.Compared with the control group,the mitochondrial membrane potential was markedly decreased in the H2O2-treated cells,accompanied by the increase of ROS (both P＜0.05).Compared with the H2O2 group,the mitochondrial membrane potential changes in the taxifolin group was increased while the ROS was decreased,with significant difference (both P＜0.05).Compared with the control group,the protein level of caspase-1 and the mRNA levels of IL-18,IL-1a,IL-1b,AIM2,ASC,NLRP3 and NLRC4 in the H2O2-treated group were significantly increased (all P＜0.05),which were attenuated in the presence of taxifolin (all P＜0.05).Conclusion:Taxifolin can protect H9C2 cells from oxidative injury,and it is able to suppress the H2O2-induced H9C2 cell pyroptosis through inhibition of AIM2,NLRP3 and NLRC4 in flammasome.

BACKGROUNDPaclitaxel plus cisplatin is an effective regimen in the treatment of non-small cell lung cancer (NSCLC), but it has severe adverse toxicities. The aim of this clinical trial is to evaluate the effect and safety of paclitaxel plus oxaliplatin compared with paclitaxel plus cisplatin in the treatment of advanced NSCLC.

METHODSFrom January, 2002 to October, 2004, 83 initially treated patients with advanced NSCLC were randomized into two groups: the trial group was treated with paclitaxel 175mg/m², and oxaliplatin 130mg/m² on day 1;and the control group was treated with paclitaxel 175mg/m² and cisplatin 80mg/m² on day 1. Both of them were repeated every 21 days and 2-6 cycles were given to patients. The evaluation of efficacy and safety was performed after chemotherapy regularly.

RESULTSAll patients were evaluable and received 2 cycles chemotherapy at least. The response rate of the trial group and control group was 34.1% (14/41) and 33.3% (14/42) respectively, median time to progression of them was 6.0 months and 5.5 months, median survival time was 10.7 months and 10.5 months, 1-year survival was 39.0% (16/41) and 40.5% (17/42) respectively. The following adverse effects of the two groups were different: the incidence rate of III+IV leukopenia was 4.9% and 28.6% in the trial group and the control group respectively, III+IV thrombocytopemia was 0 and 14.3%, III+IV nausea and vomiting was 7.3% and 26.2%. The difference of the incidence rate of III+IV nerve abnormality (9.8% and 9.5%), imparied renal function (0 and 7.1%), myalgia and anthralgia (0 and 2.4%) was insignificant.

CONCLUSIONSThe regimen of paclitaxel plus oxaliplatin have the similar efficacy and less adverse toxicities as compared to Paclitaxel plus Cisplatin in treatment of advanced NSCLC.
