Objectives:To investigate the effect of body mass index(BMI)on perioperative and long-term prognosis of patients with severe aortic stenosis(AS)after transcatheter aortic valve replacement(TAVR). Methods:This retrospective study imcluded 180 patients with severe AS who received TAVR in Fujian Provincial Hospital from January 2019 to January 2022.According to the BMI,patients were divided into four groups:low weight group(BMI<18.5 kg/m2,n=23),normal weight group(18.5 kg/m2≤BMI<24.0 kg/m2,n=65),overweight group(24.0 kg/m2≤BMI<28.0 kg/m2,n=57),obesity group(BMI≥28.0 kg/m2,n=35).The general clinical characteristics,imaging parameters,perioperative indexes,all-cause death and the incidence of other adverse cardiac events during(18.0±6.8)months follow-up were compared among different groups.Risk factors for the perioperative complications and long-term outcomes of TAVR were evaluated. Results:The prevalence of hypertension and diabetes,left ventricular end-diastolic diameter,ventricular septal thickness and left ventricular posterior wall thickness were significantly higher in the obese group than in normal weight group(all P<0.05).The level of prealbumin in low weight group was lower than in normal weight group(P<0.05).The total perioperative complications in low weight group were higher than in normal weight group(60.9%vs.12.3%,P=0.042).During(18.0±6.8)months follow-up,the incidence of all-cause death in the low weight group was significantly higher than that in normal weight group,overweight group and obese group(17.4%vs.4.6%vs.3.5%vs.5.7%,P=0.003).Kaplan-Meier survival analysis evidenced higher mortality rate in low weight group at 18 months after TAVR(log-rank P<0.01).Multivariate Cox regression analysis showed that the risk of long-term adverse cardiovascular events was significantly higher in low weight group than in normal weight group(HR=7.633,95%CI:1.012-57.564,P=0.049). Conclusions:Low weight patients with severe AS have a higher incidence of perioperative complications and a poor long-term prognosis.Such patients should appropriately strengthen their nutritional intake and adjust their body weight to normal levels before performing TAVR.

This study was aimed to verify the hypothesis that Ge-Xia Zhu-Yu (GXZY) decoction protects liver from porcine serum-induced oxidative stress through the thioredoxin system.SD rats were randomly divided into the blank control group,model group,normal rat + GXZY decoction group,model rat + GXZY group.The rat autoimmune hepatic fibrosis model was induced with porcine serum by intraperitoneal injection (0.5 mL/each rat) twice a week.And GXZY decoction (7.37 g raw material/kg· d) was simultaneously administered daily by gavage.Lipid peroxidation (LPO) levels and thioredoxin reductase (TrxR) activity in liver tissues were determined by the colorimetric method.Polymerase chain reaction (PCR) was used to analyze the transcription factor nuclear factor erythroid 2-related factor 2 (Nfe2l2,previously known as Nrf2) mRNA expression.And the western blot was used to analyze the thioredoxin-1 (Trx1) protein expression and Akt phosphorylation in the liver.The results showed that compared to the model control group,the GXZY decoction group attenuated porcine serum-induced oxidative stress,as indicated by the LPO level,in liver tissues.Furthermore,GXZY decoction significantly enhanced TrxR activity,Trx1 protein expression,Nfe2l2 mRNA expression,and Akt phosphorylation (all P＜0.05).It was concluded that the strong antioxidant properties of GXZY decoction in the porcine serum rat model was due to the enhancement of the hepatic thioredoxin system via activating Akt-Nrf2 signaling pathway.The study results provided experimental evidences for the supporting of this hypothesis.

Objective To develop plantar force model of patellofemoral pain (PFP), so as to provide theoretical references for the assessment of PFP rehabilitation. Methods The case-control study was conducted, and a total of 126 patients with PFP and 126 healthy controls matched by gender and age were enrolled in the study. The participants were tested for plantar force and pressure during level walking, and twelve plantar regions were divided and recorded. Whether the participants suffered PFP was analyzed as dependent variable, meanwhile the peak force and peak pressure in 12 plantar regions of participants at selected speed during level walking were analyzed as independent variables. Conditional logistic regression (CLR) equations of peak force and peak pressure with PFP were established, respectively. The receiver-operating characteristic (ROC) curve of the corresponding equations was derived, and the area under ROC curve was calculated to analyzed the validity of different equations on PFP assessment. Results The CLC equation of peak force in 12 plantar regions of the participants with FFP was constructed, and only peak force of lateral heel was in the equation. The CLC equation of peak pressure in each plantar region included medial heel, midfoot, 1st and 2nd metatarsals. Meanwhile, the area under ROC curve of the pressure equation was larger than that of the force equation. Conclusions Peak force and pressure at different plantar regions can be used to assess PFP during level walking, and peak pressure is more effective for assessment.

Objective: To observe the killing and clearance effect of an Er:YAG laser combined with sodium hypochlorite on Enterococcus faecalis at different depths of the root canal in vitro to provide a reference for clinical application. Methods : A total of 75 models of Enterococcus faecalis infection were successfully established and randomly divided into three groups (25 per group). Ten random samples per group underwent no processing. The remaining models in group A were treated with an Er:YAG laser combined with sodium hypochlorite 52.5 g/L. Group B was treated with 52.5 g/L sodium hypochlorite (positive control), and group C was treated with normal saline (negative control). The bacterial reduction rate was calculated for each group. The bactericidal effect on the surface of the root canal wall was observed in 5 samples by scanning electron microscopy. Results: There was no statistically significant difference (P > 0.05) between group A (100.00 ± 0.00) and group B (98.62 ± 2.01) but was a statistically significant difference between group A (100.00 ± 0.00) and group C (64.37 ± 2.45) (P < 0.05). The percentage reduction in bacteria was higher in group A (99.46 ± 2.31) than in groups B (92.89 ± 3.07) and C (56.72 ± 4.96) (P < 0.05). The decrease in bacteria was greater in group A (97.62 ± 3.73) than in groups B (72.49 ± 2.35) and C (44.42 ± 4.78) (P < 0.05). The bacterial reduction rate in group A (95.89 ± 2.46) was higher than that in groups B (63.88 ± 1.08) and C (33.31 ± 5.21) (P < 0.05). There were significant differences at different dentin depths in the bacterial reduction rates among groups A, B and C (P < 0.05). Electron microscopy analysis showed that the Er:YAG laser combined with 52.5 g/L sodium hypochlorite was better than either treatment alone at removing bacteria from the surface of the root canal wall. Conclusion An Er:YAG laser can effectively enhance the bactericidal effect of sodium hypochlorite on the inner wall of the root canal.
