Conclusion:Preoperative personality trait of patients undergoing bariatric and metabolic surgery can influence their depressive symptom and BMI.

ObjectiveTo explore the effect of serum containing Zhenwutang on myocardial mast cell apoptosis induced by angiotensin Ⅱ （AngⅡ） and the mechanism of the correlation between apoptosis and mitochondrial autophagy. MethodsIn this experiment， AngⅡ and serum containing Zhenwutang with different concentrations were used to interfere with H9C2 cardiomyocytes for 24 h， and the survival rate of H9C2 cardiomyocytes was detected by cell counting kit-8 （CCK-8） to screen the optimal concentration for the experiment. Enzyme-linked immunosorbent assay （ELISA） was used to detect the content of B-type natriuretic peptide （BNP） in cell culture supernatant， and immunofluorescence was used to detect the cell surface area to verify the construction of the myocardial mast cell model. Subsequently， the experiment was divided into a blank group （20% blank serum）， a model group （20% blank serum + 5×10^-5 mol·L^-1 AngⅡ）， low-， medium-， and high-dose （5%， 10% and 20%） serum containing Zhenwutang groups， an autophagy inhibitor group （1×10^-4 mol·L^-1 3-MA）， and autophagy inducer group （1×10^-7 mol·L^-1 rapamycin）. The apoptosis level of H9C2 cells and the changes of mitochondrial membrane potential were detected by flow cytometry. The lysosomal probe （Lyso Tracker） and mitochondrial probe （Mito Tracker） co-localization was employed to detect autophagy. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect Caspase-3， Caspase-9， B-cell lymphoma 2 （Bcl-2）， Bcl-2-related X protein （Bax）， and cytochrome C （Cyt C） in apoptosis-related pathways and the relative mRNA expression of ubiquitin ligase （Parkin）， phosphatase and tensin homolog （PTEN）-induced kinase 1 （PINK1）， and p62 protein in mitochondrial autophagy-related pathways. Western blot was used to detect cleaved Caspase-3， cleaved Caspase-9， Bax， Bcl-2， and Cyt C in apoptosis-related pathways， phosphorylated ubiquitin ligase （p-Parkin）， phosphorylated PTEN-induced kinase 1 （p-PINK1）， p62， and Bcl-2 homology domain protein Beclin1 in mitochondrial autophagy-related pathways， and the change of microtubule-associated protein 1 light chain 3 （LC3） Ⅱ/Ⅰ ratio. ResultsCCK-8 showed that when the concentration of AngⅡ was 5×10^-5 mol·L^-1， the cell activity was the lowest， and there was no cytotoxicity. At this concentration， the surface area of cardiomyocytes was significantly increased （P<0.01）， and the content of BNP in the supernatant of culture medium was significantly increased （P<0.05）. Therefore， AngⅡ with a concentration of 5×10^-5 mol·L^-1 was selected for the subsequent modeling of myocardial mast cells. Compared with the blank group， the model group and the autophagy inhibitor 3-MA group had a significantly increased apoptosis rate （P<0.01） and significantly decreased mitochondrial membrane potential （P<0.01）. The results of immunofluorescence co-localization showed that compared with the blank group， the model group had a significantly decreased number of red and green fluorescence spots. The results of Real-time PCR showed that compared with that in the blank group， the relative mRNA expression of Bax， Caspase-3， Caspase-9， Cyt C， and p62 in the model group was significantly up-regulated （P<0.01）， while the relative mRNA expression of Bcl-2， Parkin， and PINK1 was significantly down-regulated （P<0.01）. In addition， the relative protein expression of Bax， cleaved Caspase-3， cleaved Caspase-9， Cyt C， and p62 was significantly up-regulated （P<0.01）. The LC3Ⅱ/Ⅰ was significantly decreased， and the relative protein expression of Bcl-2， p-Parkin， p-PINK1， and Beclin1 was significantly down-regulated （P<0.01）. Compared with the model group， the serum containing Zhenwutang groups and the autophagy inducer group had significantly decreased apoptosis rate （P<0.01）， and the decrease ratio of mitochondrial membrane potential is significantly lowered （P<0.01） in a dose-dependent manner. Additionally， both red and green fluorescence spots became more in these groups. In the 3-MA group， the number of red and green fluorescence spots decreased significantly. The relative mRNA expression of Bax， Caspase-3， Caspase-9， Cyt C， and p62 was significantly down-regulated （P<0.05， P<0.01）， while that of Bcl-2， Parkin， and PINK1 was significantly up-regulated （P<0.01）. In the serum containing Zhenwutang groups， the relative protein expression levels of Bax， cleaved Caspase-3， cleaved Caspase-9， Cyt C， and p62 were significantly down-regulated （P<0.05，P<0.01）. The LC3Ⅱ/Ⅰ was significantly increased， and the relative protein expression levels of Bcl-2， p-Parkin， p-PINK1， and Beclin1 were significantly up-regulated （P<0.01）. ConclusionThe serum containing Zhenwutang can reduce the apoptosis of myocardial mast cells and increase mitochondrial autophagy. This is related to the inhibition of intracellular Bax/Bcl-2/Caspase-3 apoptosis pathway and regulation of Parkin/PINK1 mitochondrial autophagy pathway.

Purpose To explore the influence of thrombolysis therapy before percutaneous coronary intervention(PCI)on long-term left ventricular global and regional function in ST segment elevation myocardial infarction(STEMI)patients by cardiac magnetic resonance(CMR).Materials and Methods A retrospective analysis was conducted on 67 STEMI patients who were enrolled in a prospective study from November 2021 to August 2022 in the First Affiliated Hospital with Nanjing Medical University,the First People's Hospital of Lianyungang,the Affiliated Hospital of Jiangnan University,Changzhou No.2 People's Hospital and Huai'an Second People's Hospital and underwent CMR examination one year later.STEMI patients were divided into thrombolysis group and non-thrombolysis group according to whether a single half-dose of 5 mg recombinant staphylokinase(r-SAK)was given within two hours before the first medical contact and PCI.Based on CMR cine images,the traditional left ventricular function,global and segmental functional parameters were measured,and the differences between the two groups were compared.According to the degree of late gadolinium enhancement involvement,myocardial segments were divided into the following four types:transmural infarcted segments,non-transmural infarcted segments,locally infarcted segments,and non-infarcted segments.The parameters of the two groups were compared across these different segments.Results At the patient level,the cardiac index,left ventricular wall thickening and left ventricular wall motion in r-SAK thrombolysis group were higher than those in non-thrombolysis group(t/Z=-2.426,-4.307,-2.735,all P<0.05).At the segment level,compared with non-thrombolysis group,patients received r-SAK before primary PCI showed greater segmental radial strain in non-transmural infarcted segments(Z=-2.117,P=0.034);larger segmental wall motion in locally infarcted segments(Z=-2.235,P=0.025),and better segmental circumference strain in the non-infarcted segments(Z=-3.869,P<0.001).Conclusion The thrombolytic therapy before PCI in STEMI patients retain better long-term left ventricular global and regional function evaluating by CMR.

Objective To investigate the effects of different administration times on the efficacy and safety of subcutaneous immunotherapy using dual mite extracts in patients with allergic rhinitis(AR).Methods This study was designed as a retrospective cohort analysis.Thirty-nine mite-sensitized AR patients who completed three years of standardized dual-mite subcutaneous immunotherapy(SCIT)were included.Based on self-selected and consistently maintained injection schedules,patients were non-randomly assigned to either a morning dosing group(MD group,8:00-12:00,n=19)or an afternoon dosing group(AD group,14:00-18:00,n=20),with further subgroup stratification conducted at 2-hour intervals.Nasal and ocular symptoms were evaluated before and after treatment using the visual analog scale(VAS),and all adverse reactions were systematically recorded.Results The AD group exhibited significantly greater improvement in nasal itching compared to the MD group(median difference:-2 vs.0,U=118.5,P=0.04,effect size r=0.33).The AD group also demonstrated favorable trends toward improved sneezing,nasal congestion,rhinorrhea,and total VAS score,although these differences did not reach statistical significance.In the subgroup analysis by 2-hour intervals,the 16:00-18:00 subgroup showed greater symptom relief than the 8:00-10:00 subgroup,though the difference was not statistically significant.No significant differences were observed between the two groups in the incidence of total,local,or systemic adverse reactions(P>0.05),and no moderate or severe systemic adverse events occurred.Conclusions This preliminary retrospective analysis indicates that afternoon administration of dual-mite SCIT,particularly between 16:00 and 18:00,may enhance the improvement of nasal symptoms without elevating safety concerns.The timing of SCIT administration could therefore represent a promising avenue for treatment optimization.

Purpose To analyze the expression of SNAP23 in esophageal squamous cell carcinoma(ESCC)and its influence on invasion of ESCC cells.Methods A total of 41 cases of ESCC and paired normal adjacent tissue(NAT)were collected.The expression and localization of SNAP23 were detected by immunohistochemical EnVision method.The differences of SNAP23 expression levels between ESCC tissues and NAT tissues were compared to analyze the relationship between SNAP23 expression and clinicopathological characteristics.The expression level of SNAP23 in human immortalized esophageal epithelial cells SHEE and ESCC cell lines TE-1,TE-13 and KYSE150 were detected by Western blot.Lentiviral vector transfection technique was used to construct stable transfection cell lines with knock-down and overexpression of SNAP23 gene.The effect of SNAP23 on invasion of ESCC cell line TE-13 was evaluated by cell invasion experiment.Results The expression of SNAP23 in ESCC was significantly higher(53.7％,22/41)than that in the NAT group(19.5％,8/41),the difference was statistically significant(x2=10.303,P＜0.01).The expression level of SNAP23 in ESCC tissues was significantly correlated with maximum tumor diameter(x2=4.193,P＜0.05)and invasion depth(x2=7.264,P＜0.05),but was not correlated with patient gender,age,tumor site,tumor type,pathologic grade,vascular embolus,nerve invasion and lymph node metastasis(P＞0.05).Compared with human immortalized esophageal epithelial cells SHEE,SNAP23 was highly expressed in ESCC cell lines(P＜0.000 1).Compared with the sh-NT group,the invasion of ESCC cell line TE-13 was inhibited when SNAP23 expression was knocked down(P＜0.000 1);compared with the Vector group,the invasion of ESCC cell line TE-13 was enhanced after overexpression of SNAP23(P＜0.000 1).Conclusion SNAP23 is highly expressed in ESCC tis-sue and cell lines,and its expression level in ESCC tissues is positively correlated with tumor maximum diameter and invasion depth;SNAP23 promotes the invasion of ESCC cells.

Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.

Aim To evaluate the tyrosine nitration modification of specific proteins in vascular endothelial cells and its impact on mitochondria-mediated apoptosis.Methods Human umbilical vein endothelial cells were cultured in vitro and divided into three groups:control group(treatment with dimethyl sulfoxide),3-morphansulam(SIN-1)group,and SIN-1+Fe(Ⅲ)5,10,15,20-(tetraphenyl)porphyrin(FeTPP)group.After 24 h,the levels of hexokinase 1(HK1)nitration modification,mitochondrial membrane potential,reactive oxygen species(ROS)production,and endothelial cell proliferation and apoptosis were assessed.A human umbilical vein endothelial cell line knockout of HK1 was constructed using gene editing technology,and its proliferation and apoptosis levels were detected.Results After treatment of hu-man umbilical vein endothelial cells with peroxynitrite generator SIN-1,the level of HK1 protein nitration modification sig-nificantly increased(P＜0.01),reactive oxygen species production significantly increased,mitochondrial membrane poten-tial significantly decreased,endothelial cell proliferation ability significantly decreased,and endothelial cell apoptosis level significantly increased(all P＜0.01).Peroxynitrite decomposition catalyst FeTPP could reverse the above effect(P＜0.01).In addition,HK1 gene knockout also exhibited similar antioxidant effects,with a significant decrease in endothe-lial cell proliferation ability and a significant increase in apoptosis levels(P＜0.01).Conclusion Peroxynitrite can induce an increase in the level of nitration modification of HK1 in vascular endothelial cells,which may be achieved by pro-moting the production of mitochondrial reactive oxygen species,thereby accelerating the process of endothelial cell apoptosis.
