Microarray analysiswas used to identify a panel of candidate target genes for SL-4 acting on PLinducedulceration. Genes included some complement and coagulation cascadeand retinol metabolism pathways that are closely associated with inflammatoryresponses and gastric mucosal protective mechanisms. qRT-PCR showed thataltered expression of the selected genes, such as CYP2b2, UGT2b1, A2m, andMASP1 was consistent with the microarray results.CONCLUSIONSL-4 exerts protective effects against PL-induced gastroduodenal ulcers viareducing inflammatory cytokines and elevating expression of gastric acidinhibitory factors. Downregulation of CYP2b2 and UGT2b1 genes in retinolmetabolism and upregulation of A2m and MASP1 genes in the complement andcoagulation cascades pathways are possibly involved in SL-4-mediated protectionagainst gastroduodenal ulcer.展开更多

文摘BACKGROUND Delayed inflammatory reactions(DIRs)in alloplast rhinoplasty are a rare complication that may occur several months to years after surgery.The exact causes and mechanisms are unclear,but several triggering factors,including infections,trauma,dental procedures,and vaccination,have been reported.CASE SUMMARY A 39-year-old male patient who had undergone augmentation rhinoplasty 8 years ago had DIRs after the administration of the first dose of the mRNA Pfizer coronavirus disease 2019(COVID-19)vaccine.He suddenly had tender,erythematous swelling on his face 6 d after vaccination.As there was no improvement in the patient’s condition after the conservative treatment,surgical removal of an alloplastic nasal implant was performed.Immediately after the surgery,the DIRs and accompanying symptoms ameliorated rapidly.A histological study conducted during surgery was fibrosis and small fragments of the hyaline cartilage.CONCLUSION The correlation between DIRs and COVID-19 vaccination has not been reported yet and the exact mechanism is unclear.Because the uncontrolled inflammatory reactions on the nose leave serious sequelae,surgeons should be conscious of the correlation between COVID-19 vaccines and DIRs associated with nasal alloplastic implants.And further histological or microbiological studies should be performed to determine the cause of DIRs.

文摘BACKGROUND Thoracoscopic-assisted technology can ensure that doctors can implement minimally invasive treatment through the right intercostal incision or small incision of the lower sternum.This approach not only can achieve a cardiac correction effect equivalent to that of a thoracotomy but also has the benefit of a clear surgical field ensuring the safety of surgical treatment.AIM To investigate the effect of thoracoscopic tricuspid valvuloplasty in patients with tricuspid valve disease.METHODS A total of 41 patients with tricuspid valve disease underwent traditional thoracotomy treatment between January 2018 and June 2020.Forty-one patients with tricuspid valve disease who underwent thoracoscopic tricuspid valvuloplasty treatment between July 2020 and June 2021 in our hospital were selected as controls for our retrospective analysis.The study group underwent thoracoscopic tricuspid valvuloplasty,while traditional thoracotomy was performed in the control group.The operation conditions(the duration of extracorporeal circulation,aorta blocking,endotracheal intubation,and surgery),inflammatory response-related indices(C-reactive protein and white blood cell count)before and after surgery,parameters related to myocardial injury(myocardial troponin T,creatine kinase isoenzyme,creatine kinase,and lactate dehydrogenase),and the incidence of adverse events in the two groups was counted.RESULTS The duration of extracorporeal circulation(109.35±50.31 min),aortic occlusion(94.26±59.61 min),endotracheal intubation(12.59±3.54 h),and hospital stay(5.29±2.34 d)in the study group were shorter than those in the control group(114.91±46.98 min,101.37±61.44 min,13.11±4.01 h,7.09±3.11 d,respectively).The difference in hospital stay between the two groups was statistically significant(P<0.05).Serum C-reactive protein level(4.69±1.35 mg/L)and white blood cell count(6.21±1.97×10^(9)/L)in the study group were found to be not significantly different than those in the control group(5.01±1.18 mg/L,5.98±2.01×10^(9)/L,respectively;P>0.05).Myocardial troponin T(0.04±0.02 ng/mL),creatine kinase isoenzyme(4.02±1.11 mg/mL),creatine kinase(91.35±10.44 U/L),and lactate dehydrogenase(179.81±60.04 U/L)in the study group were also not statistically significant different than those in the control group(0.05±0.03 ng/mL,3.97±1.05 mg/mL,89.69±13.05 U/L,186.35±56.96 U/L;P>0.05).After the operation,serum C-reactive protein level(7.89±1.73 mg/L)and white blood cell count(10.76±2.35×10^(9)/L)in the study group were significantly lower than those in the control group(9.96±2.04 mg/L,14.84±3.07×10^(9)/L,respectively)(P<0.05).In addition,myocardial troponin T(0.89±0.32 ng/mL),creatine kinase isoenzyme(26.96±4.95 mg/mL),creatine kinase(608.32±202.33 U/L),and lactate dehydrogenase(282.56±101.34 U/L)in the study group were lower than those in the control group(2.61±0.69 ng/mL,34.37±6.87 mg/mL,689.94±214.64 U/L,369.15±114.46 U/L)(P<0.05).The incidence of adverse events in the study group(4.88%)was lower than that in the control group(19.51%)(P<0.05).CONCLUSION Thoracoscopic tricuspid valvuloplasty can achieve good results in treating patients with tricuspid valve disease,reduce the risk of adverse events,and promote the rapid recovery of patients.

文摘The incidence of premature ovarian failure,which is related to women’s excessive pressure and mental tension,has increased in recent years.Premature ovarian failure has become one of the diseases that seriously disturb women’s physical and mental health,and its incidence can be regarded as liver depression and qi stagnation.Patients have an increasing demand for treatment,not only for fertility with the improvement of social living standards and the development of healthcare technology.Exosomes,as small membrane vesicles containing complex RNA and proteins,have the function of mediating cell communication and transmitting information in the pathological state caused by liver-qi stagnation.Exosomes in the hypoxic microenvironment can protect cells from damage and promote the pathological process.Moreover,exosomes in an inflammatory environment can play an active anti-inflammatory role.Exosomes can reduce the apoptosis of granulosa cells by expressing miRNA and so on to restore ovarian function.The purpose of treating premature ovarian failure can be achieved in this way.This paper introduced the relationship between the three,discussed the guiding significance of Chinese medicine theories in the treatment of exosomes and premature ovarian failure,and provided new research ideas for the treatment of integrated traditional Chinese medicine and western medicine.

文摘Peroxisome proliferator-activated receptorsγ(PPARγ)is a master regulator that controls energy metabolism and cell fate.PPARγ2,a PPARγisoform,is highly expressed in the normal prostate but expressed at lower levels in prostate cancer tissues.In the present study,PC3 and LNCaP cells were used to examine the benefits of restoring PPARγ2 activity.PPARγ2 was overexpressed in PC3 and LNCaP cells,and cell proliferation and migration were detected.Hematoxylin and eosin(H&E)staining was used to detect pathological changes.The genes regulated by PPARγ2 overexpression were detected by microarray analysis.The restoration of PPARγ2 in PC3 and LNCaP cells inhibited cell proliferation and migration.PC3-PPARγ2 tissue recombinants showed necrosis in cancerous regions and leukocyte infiltration in the surrounding stroma by H&E staining.We found higher mixed lineage kinase domain-like(MLKL)and lower microtubule-associated protein 1 light chain 3(LC3)expression in cancer tissues compared to controls by immunohistochemistry(IHC)staining.Microarray analysis showed that PPARγ2 gain of function in PC3 cells resulted in the reprogramming of lipid-and energy metabolism-associated signaling pathways.These data indicate that PPARγ2 exerts a crucial tumor-suppressive effect by triggering necrosis and an inflammatory reaction in human prostate cancer.
