ObjectiveTo observe the clinical efficacy of the stasis-dispelling and detoxifying therapy in endometriosis （EMs） patients with the syndrome of kidney deficiency and blood stasis and the effects of this therapy on the expression levels of proteins related to the c-Jun N-terminal kinase （JNK） signaling pathway. MethodsA total of 72 patients with EMs due to kidney deficiency and blood stasis who met the criteria at the Integrated Traditional Chinese and Western Medicine Center for Reproduction and Genetics of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from March 2024 to February 2025 were selected and randomized into a treatment group and a control group， with 36 patients in each group. Another 36 patients undergoing in vitro fertilization-embryo transfer （IVF-ET） due to male factors alone were selected as the blank group. The treatment group took the Zishen Quyu Jiedu formula orally， while the control group and the blank group took placebos. The treatment course encompassed the cycle before ovarian stimulation and the oocyte retrieval cycle. The TCM syndrome score of kidney deficiency and blood stasis， as well as the serum level of cancer antigen 125 （CA125）， were evaluated at the time of enrollment （before treatment） and on the trigger day （after treatment）. Serum levels of sex hormones were measured on day 2 of the menstrual cycle. On the trigger day， the duration and dosage of gonadotropin （Gn） administration and the serum levels of hormones on the day of human chorionic gonadotropin （HCG） injection were assessed. Embryo outcomes were evaluated 3 days after oocyte retrieval， and clinical pregnancy rates were assessed 28 days after embryo transfer. The baseline data of three groups were observed. The TCM syndrome scores and serum CA125 levels before and after treatment were compared between the treatment and control groups. The baseline endocrine levels， Gn days， Gn dosage， hormone levels on the day of HCG administration， number of oocytes retrieved， number of 2 pronucleus （2PN） fertilizations， number of available embryos， high-quality embryo rate， and clinical pregnancy rate were also assessed in all three groups. Six patients from each group were selected for determination of the protein levels of JNK， c-Jun， and nuclear receptor subfamily 4 group A member 2 （NR4A2） in ovarian granulosa cells （GCs） on the day of oocyte retrieval by Western blot. Results（1） There were no statistically significant differences in the baseline data among three groups， indicating comparability. （2） Compared with the baseline within the same group， the treatment group showed a decrease in the syndrome score of kidney deficiency and blood stasis after treatment. After treatment， serum CA125 levels decreased in both groups （P<0.05）， with a more substantial reduction in the treatment group， resulting in a difference between the two groups （P<0.05）. （3） There were no significant differences among three groups in terms of baseline serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， and progesterone （P）， as well as the duration and dosage of Gn administration and the serum levels of LH， E₂， and P on the day of HCG administration. （4） For embryo outcomes， the number of oocytes retrieved， 2PN fertilizations， available embryos， and high-quality embryo rates in the treatment group and the blank group were higher than those in the control group （P<0.05）， and the treatment group and the blank group had similar 2PN fertilizations. （5） There were differences in clinical pregnancy rate among three groups （P<0.05）， and the treatment group had higher pregnancy rate than the control and blank groups. （6） The protein levels of JNK， c-Jun， and NR4A2 in the GCs of the treatment group were lower than those in the control group （P<0.01） and close to those in the blank group （P<0.01）. （7） No obvious adverse reactions were observed in any of the subjects during the clinical observation process. ConclusionZishen Quyu Jiedu formula can ameliorate the clinical symptoms of patients with EMs due to kidney deficiency and blood stasis， reduce the serum CA125 level， increase the number of oocytes retrieved， 2PN fertilizations， available embryos， and high-quality embryo rate， and improve pregnancy outcomes. The mechanism may involve downregulating the levels of JNK， c-Jun， and NR4A2 to reduce the apoptosis of ovarian GCs and improve the ovarian function in the patients.

Objective To investigate whether successful percutaneous coronary intervention(PCI)could improve symptoms and quality of life(QOL)in left main disease and/or 3-vessel disease patients with diabetes.Methods Patients with left main disease and/or 3-vessel disease who underwent PCI in the First Affiliated Hospital of Air Force Medical University from April 2018 to May 2021 were consecutively enrolled and subdivided into 2 groups:diabetes and no diabetes.Detailed baseline characteristics,symptoms,including dyspnea and angina,assessed with the Rose dyspnea scale(RDS),Seattle angina questionnaire(SAQ),the European quality of life-5 dimensions(EQ-5D)and 12-item short-form health survey(SF-12)questionnaire respectively,procedural details,and 1 month and 1 year follow-up data were collected.Results Among 440 left main disease and/or 3-vessel disease patients,disease was present in 176(40.00％),who had more hypertension,peripheral artery disease,and LCX lesion(all P＜0.05).The incidence of major adverse cardiovascular events(MACE)and all-cause mortality were similar between the two groups(both P＞0.05)at 1 month follow-up,while all-cause mortality in diabetes patients was significantly higher than those without diabetes at 1 year follow-up(P=0.013).Low left ventricular ejection fraction was an independent risk factor for MACE and all-cause mortality at 1 month and 1 year follow-up after successful revascularization(all P＜0.05).Most importantly,symptoms,including dyspnea and angina,and QOL were markedly improved regardless of diabetes both at 1 month and 1 year follow-up(all P＜0.05).Diabetes patients showed improved dyspnea and QOL at similar degree to the non-diabetes patients(all P＞0.05)and a more significantly relieved angina(P=0.013).Additionally,the number of chronic total occlusion(CTO)per patient was identified as an independent risk factor of dyspnea(OR 0.723,95％CI 0.525～0.997,P=0.048)and angina relief(OR 0.686,95％CI 0.473～0.995,P=0.047),and the contrast volume(OR 0.995,95％CI 0.992～0.999,P=0.008)as an independent risk factor of QOL improvement in diabetic patients.Conclusions Successful PCI is beneficial for relieving symptoms and improving quality of life in patients with diabetes who have left main disease and/or 3-vessel disease.

Staphylococcus aureus has the ability to invade bovine mammary epithelial cells and cause persistent intracellular infections.For diagnosing mastitis in cows caused by the bacterial in-fections,it is necessary to determine whether there is a persistent intracellular infection by S.au-reus within mammary epithelial cells,and to establish scientific treatment strategies and imple-ment proactive management decisions.The content of this study is the establishment of a brand new diagnostic method aimed at confirming this type of bovine disease efficiently and cost-effec-tively.The diagnostic procedure is as follows:Add 100 μL S.aureus liquid culture with a concentra-tion of 8.5 ×1010 CFU/mL to the well-grown bovine mammary epithelial cell line and co-culture at 37 degrees Celsius for 2 h to establish an intracellular infection model;After the co-cultivation is completed,add 100 μL of lysostaphin to the dish to thoroughly eliminate extracellular S.aureus.It can be confirmed that the model has been successfully established that black spherical bacteria with a diameter of approximately 1μm are observed within the sample cells using a transmission e-lectron microscope.Intracellular infection is evidenced by the observation of DNA-staining positive material within the cytoplasm of DAPI-stained sample cells,as observed through a laser confocal microscope.The sample is subjected to gram staining after being treated with 200 μL of 0.5％Tri-tonX-100 for 15 min,and intracellular infection is observed within the cytoplasm of the sample cells with Gram-positive results under oil immersion microscopy.The results of the novel"Tri-tonX-100 & gram staining method"validate that the presence of Staphylococcus aureus individu-als within bovine mammary epithelial cells is consistent with images observed under transmission electron microscopy and laser confocal microscopy.The verification results indicate that the"Tri-tonX-100 & gram staining method"is suitable for the diagnosis of S.aureus persistent intracellu-lar infection in bovine mastitis.Later,somatic cells from milk were extracted by gradient centrifu-gation and purified to obtain bovine mammary epithelial cells for clinical testing of 70 S.aureus positive mastitis cattle,which showed a positive rate of 82.9％and a negative rate of 17.1％.

Objective To evaluate the effectiveness and safety of edaravone combined with oxiracetam in the treatment of acute cere-bral infarction.Methods PubMed,Embase,Cochrane Library,CNKI,Wanfang Data and other databases were comprehensively searched from database inception until October 27,2022,to collect randomized controlled trials of edaravone combined with oxiracetam in the treatment of acute cerebral infarction(ACI).RevMan5.4software was used to analyze the collected data.Results A total of9studies involving 887 patients were included.Meta-analysis results showed that the overall effective rate and Barthel index in the observation group were significantly higher than those in the control group(OR=4.66,95％CI:2.74-7.93,P＜0.001;MD=14.57,95％CI:8.58-20.56,P＜0.001),the NIHSS scores in the observation group were significantly lower than that in the control group(MD=-5.28,95％CI:-6.42--4.13,P＜0.001).There was no significant difference in adverse effect rate between the two groups(RR=1.11,95％CI:0.63-1.95,P=0.72).Conclusion The combination of edaravone and oxiracetam in the treatment of ACI can significantly reduce NIHSS scores,and improve Barthel index and overall effective rate.The efficacy is better than edaravone alone,and a more comprehensive evaluation of safety is needed in the future.

This study aims to investigate the effect of bovine leukemia virus encoded microRNAs(BLV-miRNAs)on lactoperoxidase(LPO)in bovine mammary epithelial cells(BMECs).Firstly,the LPO content in the milk of BLV-positive cows,categorized by different viral loads,was quanti-fied by enzyme-linked immunosorbent assay(ELISA).Subsequently,BMECs were cultured in vitro and infected with(1 MOI)full-length BLV and BLV lacking miRNAs(BLV-ΔmiRNAs).Va-rious analytical techniques,including fluorescent quantitative PCR and ELISA,were used to assess LPO expression levels in different BMEC cohorts.Ten BLV-miRNAs were computationally predic-ted to target LPO using software tools such as StarMir.Based on these predictions,transfections of BLV-miRNAs were carried out and preliminary verification of their effects on target genes were performed.The results showed that compared to that of BLV-negative counterparts,the LPO levels in the milk of BLV-positive cows,stratified by high and low viral load,decreased by 8.73％and 9.68％,respectively.Invitro experiments further corroborated these trends,revealing a significant increase(P＜0.05)in LPO expression within BMECs following the deletion of BLV-miRNAs compared to the group infected with full-length BLV-infected group.Computational target site pre-dictions implicated BLV-miR-B1-5p,B3-3p,and B4-5p in the collective regulation of the LPO gene.Transfection of BLV-miR-B1-5p into BMECs resulted in a significant downregulation of LPO gene expression(P＜0.05),with the effect intensifying proportionally with the transfection dose.Simi-larly,the transfection of BLV-miR-B4-3p into BMECs significantly reduced LPO gene expression(P＜0.05)without showing a dose-dependent behavior.In conclusion,this research indicates that BLV-miRNAs can suppress LPO expression in BMECs.

Objective To explore the clinical efficacies of different surgical methods for elderly patients with lumbar tuberculosis.Methods The clinical data of 289 elderly patients with lumbar tuberculosis admitted to Hebei Chest Hospital from August 2018 to August 2021 were retrospectively analyzed.According to surgical methods,the patients were divided into the posterior group(109 cases),the anterior and posterior combination group(81 cases),and the anterior group(99 cases).The time of bone graft and fusion,operation time,hospital stay,intraoperative blood loss,and complications of the three groups were collected and compared among the three groups.The spine Cobb angle was regularly determined,the correction degree was calculated;the levels of erythrocyte sedimentation rate(ESR),white blood cell count(WBC),and C-reactive protein(CRP)were collected and compared among the three groups;and the Frankel grading and visual analogue scale(VAS)scores of the three groups were compared.Results After a 2-year follow-up,there was no significant difference in the time of bone graft and fusion among the three groups(P>0.05),the anterior group had the shortest operation time,the posterior group had the shortest hospital stay,and the lowest intraoperative blood loss and incidence of complications,with statistically significant differences(P<0.05).The correction degree of the anterior and posterior combination group was better than that of the posterior group and the anterior group(P<0.05),and the Cobb angles after operation and at the last follow-up in the posterior group was better(P<0.05).The anterior and posterior combination group had better improvement effect on CRP and ESR at the last follow-up(P<0.05),the WBC level of the posterior group was lower(P<0.05).The proportions of patients in grade E of Frankel grading at the last follow-up in the three groups were higher than those after surgery(P<0.05);compared with the preoperative period,the VAS scores at the last follow-up of the three groups decreased(P<0.05),and the VAS score of the posterior group was lower(P<0.05).Conclusion The effects of anterior surgery,posterior surgery and anterior and posterior combined surgery in the treatment of elderly lumbar tuberculosis are good,and the approach method can be scientifically and reasonably formulated according to patients' physical condition to improve the clinical treatment effect.

Objective To investigate the effect of pristimerin(PM)on adriamycin(ADM)resistance in osteosarcoma cells and its mechanism.Methods The ADM resistant cells MG-63/ADR was established in vitro by using the ADM increasing concentration gradient long-term culture method,CCK-8 was used to detect the effects of different concentrations of ADM on the viability of osteosarcoma cells MG-63 and MG-63/ADR cells to verify the drug resistance of ADM;subsequently,MG-63/ADR cells were randomly divided into the MG-63/ADR group(normal culture),low-dose PM group(adding 0.5 μmol/L PM),middle-dose PM group(adding 1.0 μmol/L PM)and high-dose PM group(adding 2.0 μmol/L PM).The cell viability of each group under different concentrations of ADM treatment was detected by CCK-8;the sensitivity of cells to ADM in each group was detected by plate clone formation assay;the cell morphology of each group was observed under microscope;the cell apoptosis level was detected by flow cytometry;Western blot was used to detect the expression of phosphorylated mammalian STE20-like protein kinase 1(p-MST1),MST1,phosphorylated large tumor suppressor 1(p-LATS1),LATS1,phosphorylated Yes associated protein(p-YAP)and YAP proteins.Results With the intervention of 25,125,625,3 125 and 15 625 ng/mL ADM,the activity of MG-63/ADR cells was significantly higher than that of MG-63 cells(P＜0.05),which indicated that the ADM resistant cell model was successfully established.Compared with the MG-63/ADR group,the number of cells in the low,middle and high-dose PM groups decreased,and the cells gradually shrank,the spacing between cells became larger,and the cell viability,cell clonal formation rate and p-YAP/YAP level decreased(P＜0.05),the apoptosis rate and the levels of p-MST1/MST1 and p-LATS1/LATS1 significantly increased(P＜0.05).Conclusion The inhibitory effect of PM on ADM resistance in osteosarcoma cells may be related to the activation of Hippo pathway and the downregulation of YAP signal.
