Objective To explore causal relationship between 25-hydroxyvitamin D[25(OH)D]and ankylosing spondylitis(AS).Methods Genetic data of 25(OH)D and AS were extracted from the genome-wide association study.The causal effect of 25(OH)D on AS was estimated by MR-Egger regression method,weighted median,inverse variance weighted(IVW),simple mode and weighted mode,and sensitivity analysis was conducted for verification.Results The IVW results indicated that there was a causal relationship between 25(OH)D concentration and AS(OR=0.805,95％CI:0.686-0.944,P=0.008),and the maximum likelihood ratio(OR=0.799,95％CI:0.678-0.940,P=0.007)showed consistent results.The IVW results of the reverse Mendelian randomization study showed that there was no causal relationship between the two(OR=1.019,95％CI:0.995-1.043,P=0.110).In addition,MR-Egger intercept,Cochran Q test,"leave-one-out"and MR-PRESSO analysis showed no horizontal pleipotency or heterogeneity.Conclusion There may be a genetic causal relationship between the concentration of 25(OH)D and the onset of AS.AS cannot cause changes in the concentration of 25(OH)D in the body.

Objective To investigate the relationship between sleep disorders and coronary heart disease through big data combined with Mendelian randomization analysis.Methods Data from 2005 to 2018 National Health and Nutrition Examination Survey in the United States were utilized.Logistic regression analysis was employed to evaluate the association between sleep disorders and coronary heart disease,while analyzing relevant influencing factors.A two-sample Mendelian randomization approach was implemented using Genome-Wide Association Studies to establish causal relationships.Results Logistic regression analysis demonstrated a significant association between sleep disorders and coronary heart disease(P＜0.001),with the neutrophil-to-lymphocyte ratio serving as a mediating factor in this relationship(P＜0.001).Mendelian randomization analysis revealed a positive correlation between sleep disorders and coronary heart disease(OR=1.030,95％CI:1.01-1.04).Conclusion Sleep disorders can increase the risk of coronary heart disease by activating inflammatory factors.

Objective To investigate the effect of butorphanol combined with parecoxib sodium on patient-controlled intravenous analgesia(PCIA)after uvulo-palato-pharyngo-plasty(UPPP).Methods Eighty patients who were admitted to our hospital from October 2021 to May 2023 and planned to receive UPPP were collected,and they were randomly assigned to the paroxicib sodium group(D group),the butorphanol low-dose group(B1 group),the butorphanol medium dose group(B2 group),and the butorphanol high-dose group(B3 group),with 20 cases in each group.Patients in the D group received 40 mg of paroxycoxib sodium with 0.9% sodium chloride injection for analgesia,and patients in the B1 group,the B2 group,and the B3 group were combined with 3.0 μg·kg-1·h-1,4.0 μg·kg-1·h-1,and 5.0 μg·kg-1·h-1 of butorphanol respectively on the basis of D group.The heart rate and mean arterial pressure before PCIA and 2 hours,12 hours,24 hours,and 48 hours after PCIA were compared among the four groups;the pain visual analogue scale(VAS)score,Ramsay score 2 hours,12 hours,24 hours,and 48 hours after PCIA were compared among the four groups;the number of PCIA compression,and incidence of adverse reactions were recorded.Results There was no statistically significant difference in the heart rate or mean arterial pressure before PCIA and 2 hours,12 hours,24 hours,and 48 hours after PCIA among the four groups(P>0.05).Compared with the D group,the VAS scores 2 hours,12 hours,24 hours,and 48 hours after PCIA of the B1,B2,and B3 groups significantly decreased(P<0.05),and the higher the dose of butorphanol,the lower the VAS score(P<0.05).Compared with the D group,the Ramsay scores 2 hours,12 hours,24 hours,and 48 hours after PCIA of the B1,B2,and B3 groups obviously increased(P<0.05),and the higher the dose of butorphanol,the higher the Ramsay score(P<0.05).The total incidence of adverse reactions in the B3 group was obviously higher than that in the D group,the B1 group,and the B2 group(P<0.05).Compared with the D group,patients in the B1,B2,and B3 groups had significantly fewer PCIA compressions(P<0.05),and the higher the dose of butorphanol,the fewer the PCIA compressions(P<0.05).Conclusion The effect of butorphanol combined with parecoxib sodium in PCIA after UPPP is better,and combined with 4.0 μg·kg-1·h-1 parecoxib sodium has more significant analgesic effect and higher safety.

Objective To explore the value of expression levels of serum thioredoxin-interacting protein(TXNIP)and baculoviral IAP repeat-containing protein 5(BIRC5)in clinical staging and efficacy monitoring in patients with primary laryngeal cancer(PLC).Methods From June 2020 to January 2023,a total of 68 pa-tients with PLC accepted by the hospital were collected as PLC group,and 80 patients with benign lesions were set as the benign tumors group.After six months of treatment,patients in the PLC group were separated into the treatment effective group(50 cases)and the treatment ineffective group(18 cases)according to the RECIST solid tumor efficacy evaluation criteria.Enzyme linked immunosorbent assay(ELISA)was applied to detect the levels of TXNIP and BIRC5 in serum of each group;the diagnostic efficacy of TXNIP and BIRC5 in staging PLC and the predictive efficacy of PLC patients were analyzed using the receiver operating characteris-tic(ROC)curve.Results There were statistically significant differences in the expression levels of TXNIP and BIRC5 in the serum between the PLC group and the benign tumors group(P＜0.05).The level of serum TXNIP in the treatment effective group[(99.52±14.12)pg/mL]was obviously higher than that in the treat-ment ineffective group[(85.19±15.17)μg/mL],and the difference was statistically significant(t=3.621,P＜0.05),while the BIRC5 expression level[(15.26±3.65)pg/mL]was obviously lower than that in the treatment ineffective group[(19.13±3.74)pg/mL],and the difference was statistically significant(t=3.833,P＜0.05).The serum TXNIP expression level in early PLC patients[(101.39±12.85)pg/mL]was obviously higher than that in late stage patients[(91.27±13.36)μg/mL],and the difference was statistically significant(t=3.154,P＜0.05),while the BIRC5 expression level[(14.43±3.07)pg/mL]was obviously lower than that in late stage patients[(17.74±3.04)pg/mL],and the difference was statistically significant(t=4.439,P＜0.05).The area under the curve(AUC)of serum TXNIP and BIRC5 in diagnosing PLC stag-ing was 0.829(95％CI:0.718-0.909)and 0.795(95％CI:0.679-0.883),respectively,with sensitivity of 81.58％and 89.47％,and the AUC of TXNIP combined BIRC5 in diagnosing PLC staging was 0.899(95％CI:0.802-0.959),with sensitivity of 94.74％.The AUC of serum TXNIP and BIRC5 in predicting the effi-cacy of PLC patients was 0.818(95％CI:0.705-0.901)and 0.761(95％CI:0.642-0.856),respectively,the AUC of the combination of the two was 0.921(95％CI:0.830-0.973),which had higher predictive efficiency(P＜0.05).Conclusion TXNIP is lowly expressed in the serum of patients with PLC,while BIRC5 is highly expressed in the serum of patients with PLC.The combination detection of TXNIP and BIRC5 has certain effi-cacy in the diagnosis of PLC staging and predicting the efficacy of PLC patients.

Objective To study the effect of interleukin-15(IL-15)on lipopolysaccharide(LPS)-induced apoptosis of septic cardiomyocytes and its related mechanism.Methods H9C2 cells were divided into control group(H9C2 cells in conventional culture),apoptosis group(LPS-induced myocardial cell injury model was established),and intervention group(10 ng/ml recombinant rat IL-15 was used in myocardial H9C2 cell injury model for 6 h).The effects of IL-15 on H9C2 cell proliferation and apoptosis were detected by methyl thiazolyl tetrazolium(MTT)assay and flow cytometry,the level of mitochondrial membrane potential was detected by staining of tetramethylrhodamine ethyl ester(TMRE).The sepsis mouse model was established by intraperitoneal injection of 10 mg/kg LPS,and 100 μl of normal saline containing 100 μg/ml IL-15 was injected intraperitoneally.HE staining was used to evaluate the pathological injury of mouse myocardium.The indexes of oxidative stress in mouse myocardium were detected by ELISA.The effects of IL-15 on the expression of heme oxygenase 1(HO-1)and NF-E2-related factor 2(Nrf2)mRNAs and proteins in myocardium of mouse sepsis model were detected by real-time fluorescence quantitative PCR and Western bloting.Results The apoptosis rate of H9C2 cells in the apoptosis group was significantly higher than that in the control group(47.9%±5.1%vs.2.1%±0.3%,P<0.05).The apoptosis rate of H9C2 cells in the intervention group was 20.7%±2.7%,which was significantly lower than that in the apoptosis group(P<0.05).LPS could significantly inhibit the proliferation of myocardial cells,while IL-15 could inhibit LPS-induced decrease in myocardial cell viability(P<0.05).The relative mitochondrial membrane potential of myocardial H9C2 cells in the apoptosis group was significantly lower than that in the control group(2.6±4.6 vs.7.4±5.2,P<0.05).The relative mitochondrial membrane potential of myocardial H9C2 cells in the intervention group was 4.2±4.9,which was significantly higher than that in the apoptosis group(P<0.05).LPS significantly enhanced the loss of mitochondrial membrane potential of myocardial H9C2 cells,and IL-15 intervention weakened the loss of mitochondrial membrane potential of H9C2 cells induced by LPS(P<0.05).HE staining revealed obvious myocardial tissue damage and inflammatory cell infiltration in mouse sepsis model.IL-15 ameliorated LPS-induced myocardial injury in mice.The expression levels of superoxide dismutase(SOD)and total antioxidant capacity(T-AOC)in myocardium of sepsis mice were significantly lower than those in normal mice,while the expression level of malondialdehyde(MDA)in sepsis mice was significantly higher than that in normal mice(P<0.05).After IL-15 intervention,the expression of SOD and T-AOC in myocardium of sepsis mice was increased,and the expression of MDA was decreased(P<0.05).The mRNA and protein expression levels of HO-1 and Nrf2 were low in myocardium of normal mice.The mRNA and protein expression levels of HO-1 and Nrf2 in myocardium of sepsis mice were significantly higher than those in normal mice(P<0.05).After IL-15 intervention,the mRNA and protein expression levels of HO-1 and Nrf2 were significantly increased in myocardium of sepsis mice(P<0.05).Conclusion IL-15 can protect cardiomyocyte apoptosis induced by sepsis and decrease myocardial injury in sepsis mice.The mechanism may be related to the activation of HO-1/Nrf2 signaling pathway and the inhibition of myocardial oxidative stress in septic mice.
