Objective To evaluate the performance and clinical application value of EasyNAT nucleic acid test kits for influenza A virus(Flu A),influenza B virus(Flu B),and Mycoplasma pneumoniae(MP)based on cross-primed amplification(CPA)technology.Methods In compliance with relevant standards,the detection limits,cross-reactivity,and anti-interference abilities of the EasyNAT Flu and MP nucleic acid test kits were validated using influenza(Flu)and MP reference materials.Additionally,a total of 811 suspected Flu or MP infection patients who visited the hospital from January 1 to July 5,2024 were enrolled in this study.Their oropharyngeal swabs were collected and tested using reverse transcription quantitative polymerase chain reac-tion(RT-qPCR)as the gold standard to evaluate the concordance and compliance of the EasyNAT Flu and MP nucleic acid test kits,thus assessing their clinical application value.Results The EasyNAT Flu and MP nucleic acid test kits yielded positive results in 8 repeated tests at the detection limit concentrations of the ref-erence materials.No pathogen-specific peaks were detected in Flu and MP negative samples that had been spiked with common cross-reacting pathogens.Furthermore,the detection results of Flu or MP positive sam-ples were unaffected by the presence of interfering substances.Among the 811 clinical samples,the sensitivity of the EasyNAT Flu A test was 97.33%,and the sensitivity for Flu B was 98.47%,both with a specificity of 98.04%.The EasyNAT MP nucleic acid test showed a sensitivity of 97.95%and specificity of 99.03%.The results demonstrated a high degree of agreement with RT-qPCR(Kappa values were over 0.900).Further-more,detection rates of the EasyNAT Flu test kits showed no difference in positive samples with different Ct values(Flu A:χ2=4.20,P=0.08;Flu B:χ2=2.22,P=0.31)and MP test kits showed significant differences in positive samples with different cycle threshold values(χ2=11.84,P<0.01).Conclusion The EasyNAT Flu and MP nucleic acid test kits exhibit excellent detection performance with high sensitivity and specificity.Moreover,the products are easy to operate,offer rapid detection,and provide accurate results.These features make them suitable for primary healthcare settings,with significant potential for clinical application.

Objective:To investigate the clinical value of continuous Bougie tube use in symmetrical three-port laparoscopic sleeve gastrectomy (LSG).Methods:The retrospective cohort study was conducted. The clinical data of 105 patients who underwent symmetrical three-port LSG at The First Hospital of Shanxi Medical University from October 2021 to October 2024 were collected. There were 57 males and 48 females, aged 27(range, 19-59)years. Of the 105 patients, 52 cases with continuous Bougie tube use during the surgery were divided into continuous group, while 53 cases with intermittent Bougie tube use were divided into intermittent group. Observation indicators: (1) surgical situations; (2) complications. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Results:(1) Surgical situations. All 105 patients underwent symmetrical three-port LSG. The operation time was (57±4)minutes versus (76±4)minutes for the continuous group and the intermittent group, volume of intraoperative blood loss was (26±6)mL versus (59±9)mL, time to first out-of-bed activities was (218±8)minutes versus (299±9)minutes, time to first anal exhaust was (19.6±2.9)hours versus (25.8±2.8)hours, visual analogue scale score for pain at 6 hours postoperatively was 2.3±1.0 versus 4.7±1.0, and duration of postoperative hospital stay was (1.5±0.6)days versus (3.1±0.9)days for the two groups, respectively. There were significant differences in the above indicators between the two groups( t=26.92, 22.31, 48.91, 11.15, 13.25, 10.21, P<0.05). (2) Complications. No severe postopera-tive complication occurred in any of the 105 patients. There were 26 cases and 38 cases with nausea and vomiting at 2 hours postoperatively, showing a significant difference between them ( χ2=5.19, P<0.05). Conclusion:Compared to intermittent Bougie tube use, continuous Bougie tube use during symmetrical three-port LSG can significantly shorten operation time and duration of postoperative hospital stay, reduce intraoperative bleeding and postoperative pain, accelerate recovery of patients, and lower the incidence of complications.

Pulmonary fibrosis， chronic obstructive pulmonary disease， acute lung injury， asthma， and infectious pneumonia are common pulmonary inflammatory diseases worldwide. There is evidence that mitochondria produce a large amount of reactive oxygen species （ROS） when stimulated by inflammation， leading to oxidative stress that affects the onset and progression of pulmonary inflammatory diseases. With in-depth research， traditional Chinese medicine （TCM） has made significant progress in the treatment of pulmonary inflammatory diseases. An increasing amount of evidence indicates that single TCM and their active components， as well as TCM compound formulas， can improve mitochondrial oxidative stress status through multi-target and multi-pathway mechanisms， thereby effectively treating pulmonary inflammatory diseases. Currently， there is a lack of systematic review and summary of TCM research in this field both domestically and internationally. Therefore， this article aims to summarize and conclude the mechanisms by which TCM regulates mitochondrial oxidative stress to intervene in pulmonary inflammatory diseases， providing a scientific basis for its clinical application and offering new ideas and references for in-depth research on the prevention and treatment of pulmonary inflammatory diseases with TCM.

ObjectiveTo investigate the antidepressant effect of Sinisan （SNS） by regulating glycogen aynthase kinase-3β （GSK-3β）/tumor necrosis factor alpha-induced protein 3（A20）/CCAAT enhancer binding protein β（C/EBPβ） to inhibit the activation of microglia. MethodA total of 72 male C57/6J mice were randomly divided into the normal group， model group， fluoxetine group （5.0 mg·kg^-1）， low-dose Sinisan group （4.9 g·kg^-1）， medium-dose Sinisan group （9.8 g·kg^-1）， and high-dose Sinisan group （19.6 g·kg^-1）， with 12 mice in each group. After one week of adaptive feeding， chronic unpredictable mild stress （CUMS） was performed to establish the depression model. In the fifth week， drug treatment was conducted for four weeks. In the ninth week， behavioral tests were performed， including sucrose preference test （SPT）， open field test （OPT）， elevated plus maze （EPM） test， and forced swimming test （FST）. Western blot was used to detect the expression levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， nitric oxide synthase （iNOS）， GSK-3β， A20， and C/EBPβ in the cortex. The expression of M1-polarized ionized calcium-binding adapter molecule 1 （Iba1） and cluster of differentiation 68 （CD68） in microglia was detected by immunofluorescence. ResultAfter eight weeks of CUMS， compared with the normal group， the mice in the model group had a significantly reduced sucrose preference rate （P<0.01）， and the activity in the central area of the OPT was significantly reduced （P<0.01）. The activity in the open arm area of the EPM test was significantly reduced （P<0.05）， and the immobility time of FST was increased （P<0.01）. The expression levels of inflammatory proteins IL-1β， IL-6， and iNOS were increased （P<0.01）， and the fluorescence co-localization index of Iba1 and CD68 was increased （P<0.05）. The protein expression levels of GSK-3β and C/EBPβ were significantly increased （P<0.05， P<0.01）. After four weeks of SNS intervention， compared with the model group， the mice in the SNS group had significantly increased sucrose preference rate （P<0.01）， significantly increased activities in the central area and the open arm area in the OPT and the EPM test （P<0.05）， and significantly reduced immobility time in the FST （P< 0.01）. The protein expression levels of IL-1β， IL-6， and iNOS were significantly decreased （P<0.05）， and the fluorescence co-localization index of Iba1 and CD68 was decreased in the high-dose SNS group （P<0.05）. The protein expression levels of GSK-3β and C/EBPβ in the medium-dose and high-dose SNS groups were significantly decreased （P<0.01）， and that of A20 was significantly increased （P<0.01）. ConclusionThe antidepressant effect of SNS is related to the regulation of GSK-3β/A20/C/EBPβ protein expression and the inhibition of M1-type activation of microglia.

ObjectiveTo investigate the mechanism of salvianolic acid F （Sal F） in repairing the high glucose-induced injury in human kidney-2 （HK-2） cells via the B-cell lymphoma-2 （Bcl-2）-associated X protein （Bax）/cysteinyl aspartate-specific proteinase 3 （Caspase-3）/gasdermin-E （GSDME） pathway. MethodThe cell counting kit-8 （CCK-8） was used to measure the relative viability of HK-2 cells exposed to high glucose and different concentrations （2.5， 5， 10， 20 μmol·L^-1） of Sal F and the relative viability of HK-2 cells treated with Sal F for different time periods. The levels of lactate dehydrogenase （LDH） and interleukin-1β （IL-1β） in the supernatant of the cell culture were measured by the LDH assay kit and enzyme-linked immunosorbent assay （ELISA） kit， respectively. Flow cytometry combined with Annexin V-FITC/propidium iodide （PI） and Hoechst 33342/PI staining was employed to reveal the proportion of PI-positive HK-2 cells exposed to high glucose. Western blotting was employed to determine the protein levels of Bax， Bcl-2， cytochrome C， cysteinyl aspartate-specific proteinase （Caspase）-9， Caspase-3， and GSDME in the HK-2 cells exposed to high glucose and treated with Sal F. The 2，7-dichlorodihydrofluorescein diacetate fluorescence probe （DCFH-DA） and mitochondrial membrane potential assay kit （JC-1） were used to determine the production of reactive oxygen species （ROS） and the mitochondrial membrane potential in the HK-2 cells exposed to high glucose and treated with Sal F. ResultCompared with the blank group， the model group showed decreased cell viability （P<0.01）， elevated levels LDH and IL-1β， increased proportion of PI-positive cells （P<0.01）， up-regulated protein levels of Bax， cytochrome C， Caspase-9， Caspase-3， and GSDME （P<0.01）， down-regulated protein level of Bcl-2 （P<0.01）， decreased mitochondrial membrane potential， and excessive ROS accumulation. Compared with the model group， Sal F repaired the high glucose-induced injury in HK-2 cells （P<0.05）， lowered the levels of LDH and IL-1β （P<0.05， P<0.01）， and decreased the proportion of PI-positive cells （P<0.01）. In addition， Sal F down-regulated the protein levels of Bax， cytochrome C， Caspase-9， Caspase-3， and GSDME and up-regulated the protein level of Bcl-2 （P<0.05， P<0.01）， increased the mitochondrial membrane potential， and decreased the accumulation of ROS in HK-2 cells. ConclusionSal F can reduce the production of ROS， restore the balance of mitochondrial membrane potential， and inhibit pyroptosis via the Bax/Caspase-3/GSDME signaling pathway to repair the high glucose-induced injury in HK-2 cells.
