OBJECTIVE To discuss the impact of Wenyang lishui formula on ventricular remodeling in rats with pulmonary hypertension-induced right heart failure （RHF） based on the Hippo/Yes-associated protein （YAP） signaling pathway. METHODS Ten rats were randomly selected as the control group. The remaining 63 rats were given a single intraperitoneal injection of monocrotaline to establish the pulmonary hypertension-induced RHF model. The 50 rats that successfully underwent the model establishment were randomly divided into the RHF group， low-dose group of Wenyang lishui formula （4.25 g/kg）， high-dose group of the Wenyang lishui formula （17.00 g/kg）， furosemide group （20 mg/kg）， and high-dose group of Wenyang lishui formula+ Hippo/YAP signaling pathway activator group （17.00 g/kg of Δ Wenyang lishui formula+16 mg/kg of PY-60）， with 10 rats in each group. The rats in each group were given the corresponding drug solution or normal saline by gavage or/andtail vein injection， once a day， for 4 consecutive weeks. During the experiment， the general conditions of the rats in each group were observed； after the last administration， the right ventricular diameter， right atrial diameter， end-diastolic volume， pulmonary artery blood flow acceleration time （PAAT） and its ratio to ejection time （ET） （PAAT/ET）， pulmonary artery pressure and its ratio to pulmonary arterial flow velocity （pulmonary artery pressure/velocity） were measured. The plasma levels of brain natriuretic peptide and angiotensin Ⅱ （Ang Ⅱ） were detected. The pathological changes of the right ventricular tissue were observed， and the collagen volume fraction， the phosphorylation levels of the large tumor suppressor 1/2 （LATS1/2） and YAP， and the protein expression of the transcriptional coactivator of PDZ-binding motif （TAZ） were also detected. RESULTS Compared with the RHF group， the rats in Wenyang lishui formula low-dose and high-dose groups showed improved hair color， movement， diet， and mental state. The atrophy of right ventricular myocardial cells， the increase of inflammatory cells， collagen deposition， and hypertrophy of myocardial fibers were significantly alleviated. The right ventricular internal diameter， right atrial internal diameter， end-diastolic volume， pulmonary artery pressure， pulmonary artery pressure/velocity， the plasma levels of brain natriuretic peptide and AngⅡ ， collagen volume fraction， the phosphorylation level of YAP and protein expression of TAZ were significantly decreased， while the PAAT， PAAT/ET and the phosphorylation level of LATS1/2 were significantly increased （P＜0.05）. PY-60 could significantly reverse the improvement effects of high-dose Wenyang lishui formula on the above quantitative indicators （P＜ 0.05）. CONCLUSIONS Wenyang lishui formula can restore the right heart function of pulmonary hypertension-induced RHF rats， reduce their pulmonary artery pressure， alleviate the pathological changes in their cardiac tissues， and the above effects may be related to the activation of Hippo expression and the inhibition of YAP phosphorylation.

Objectives:To investigate the relationship between total ischemic time(TIT)and the risk of major adverse cardiovascular events(MACE,including all-cause death,non-fatal myocardial infarction,non-fatal ischemic stroke)within 1 year after primary percutaneous coronary intervention(PPCI)in patients with ST segment elevation myocardial infarction(STEMI)with TIT≤720 minutes. Methods:A total of 1 812 STEMI patients who underwent PPCI and had a TIT≤720 minutes in the Chest Pain Center of the General Hospital of the Southern Theatre Command of PLA from January 1,2011 to December 31,2021 were selected as the research subjects.Logistic regression and Cox regression models were used to analyze the association between TIT and the risk of MACE in the hospital and within 1 year after discharge.The restricted cubic spline(RCS)analysis was used to analyze the dose-response relationship between TIT and the risk of MACE. Results:Among 1 812 patients,the incidence of MACE during hospitalization was 3.26%,and the incidence of MACE within 1 year after discharge was 6.84%in 1 651 patients who survived.RCS analysis showed that TIT had an approximate logarithmic linear relationship with the risk of MACE during hospitalization and within 1 year after discharge,and the risk of MACE increased with longer TIT.Multivariate logistic regression analysis showed that compared with the group with a TIT of≤480 minutes,the risk of MACE during hospitalization increased by 77.7%(OR=1.777,95%CI:1.020-2.929,P=0.038)in the group with a TIT of more than 480 minutes.Multivariate Cox proportional hazards regression analysis showed that compared with the group with a TIT of≤280 minutes,the risk of MACE within 1 year after discharge increased by 106.7%(HR=2.067,95%CI:1.384-3.089,P<0.001)in the group with a TIT of more than 280 minutes. Conclusions:In STEMI patients after PPCI,the risk of MACE during hospitalization significantly increases when TIT exceeds 480 minutes,and the risk of MACE within 1 year after discharge significantly increases when TIT exceeds 280 minutes.

Objective:To evaluate the effect of obesity on the displacement of a left-sided double-lumen tube (DLT) during positional changes.Methods:This was a prospective cohort study. Six hundred and two patients who underwent elective chest surgery and required insertion of a left-sided DLT from February 2020 to November 2023 in our hospital were selected and divided into 2 groups based on the body mass index (BMI): obesity group (BMI≥28 kg/m 2,n=208) and non-obesity group (18.5 kg/m 2≤BMI<28 kg/m 2,n=394). General characteristics of patients, history of chest surgery, DLT model, depth of DLT placement in supine position, height/depth of placement (H/D) ratio, and distance of DLT displacement were recorded. DLT displacement was defined as a displacement distance of ≥15 mm. The logistic regression was used for analysis of the relationship between BMI and left DLT shift during positional changes. The receiver operating characteristic curve was used to evaluate the accuracy of BMI in predicting the left-sided DLT displacement during positional changes. Results:Compared with non-obese group, the depth of DLT placement was significantly reduced, the H/D ratio was increased, the distance of DLT displacement was increased, and the incidence of DLT displacement was increased in obese group ( P<0.05). The results of binary logistic regression analysis showed that a BMI≥28 kg/m 2 was an independent risk factor for DLT displacement ( OR value [95% confidence interval]=4.18 (2.36-7.38), P<0.001). The sensitivity of BMI in predicting the left-sided DLT displacement during positional changes was 77.4%, and the specificity was 69.6%, with an optimal cutoff value of 27.48 kg/m 2 and an area under the receiver operating characteristic curve of 0.757. Conclusions:Obesity can increase the probability of the left-sided DLT displacement during positional changes.

Objective:To compare the effects of left paratracheal pressure (LPP) and cricoid pressure (CP) during mask ventilation in obese patients.Methods:Sixty patients of either sex, aged 18-60 yr, with 28 kg/m 2≤body mass index<35 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for general anesthesia, were divided into 2 groups ( n=30 each) using a random number table method: LPP group and CP group. In LPP group, pressure was applied beside the trachea, above the clavicle towards the vertebral direction, while in CP group, pressure was applied downwards to the cricoid cartilage, with a force of pressure between 25-35 N. The spatial relationship between the esophagus, trachea, and cricoid cartilage, the presence of air shadows in the gastric antrum during mask ventilation, and the cross-sectional area (CSA) of the gastric antrum before and after mask ventilation as well as the airway pressure during mask ventilation were observed. Results:In both groups, the esophagus was located in the left of the trachea in the supraclavicular region. There were no statistically significant differences in the airway pressure during mask ventilation and the CSA of the gastric antrum prior to mask ventilation between the two groups ( P>0.05). Compared to LPP group, the proportion of patients with air shadows in the gastric antrum during mask ventilation was significantly increased, and the CSA of the gastric antrum was increased after mask ventilation in CP group ( P<0.05). Conclusions:Compared to CP, LPP can decrease the development of air entering the stomach during mask ventilation and reduce the CSA of the gastric antrum after mask ventilation in obese patients.

Objective To compare the clinical effects of minimally invasive percutaneous plate osteosynthesis (MIPO) and minimally invasive intramedullary nailing osteosynthesis (MINO) in the treatment of humeral shaft fractures. Methods The clinical data of 53 patients with humeral shaft fractures treated with MIPO and MINO were retrospectively analyzed. The patients were divided into MIPO group of 25 patients and MINO group of 28 patients according to differed surgical approaches. The operation time, blood loss, length of hospital stay, fracture healing time, University of California at Los Angeles (UCLA) shoulder function score at 1 year postoperatively, and Mayo elbow performance score at 1 year postoperatively were compared between the two groups. Results All 53 patients successfully completed the surgery, and no postoperative complications such as surgical site infection, radial nerve injury, fracture nonunion, implant breakage, or loosening occurred. There were no statistically significant differences between the two groups in terms of operation time, blood loss, length of hospital stay, fracture healing time, and Mayo elbow performance score at 1 year postoperatively (P>0.05). The UCLA shoulder function score at 1 year postoperatively was better in the MIPO group than in the MINO group (P < 0.05). One patient in the MIPO group experienced wound fat liquefaction, and one patient in the MINO group experienced radial nerve palsy. Conclusion Both MIPO and MINO can achieve satisfactory results in the treatment of humeral shaft fractures, and both minimally invasive techniques are worthy of clinical promotion. However, MIPO has lesser impact on shoulder function.

Objective:To evaluate the relationship between postoperative delirium and preoperative frailty in elderly patients undergoing non-cardiac surgery.Methods:Elderly patients undergoing non-cardiac surgery at our hospital from March 2019 to July 2022 were collected and their age, comorbidities, gender, smoking history, type of surgery, preoperative albumin, duration of surgery, duration of anesthesia, postoperative hypotension, educational level, nutritional status, American Society of Anesthesiologists (ASA) Physical Status classification, postoperative admission to ICU or not, intraoperative bleeding and preoperative frailty status were collected. The patients were divided into delirium group and non-delirium group according to whether postoperative delirium occurred. The risk factors for postoperative delirium were analyzed by multivariate logistic regression analysis, and the receiver operating characteristic curve was drawn to analyze the value of risk factors in predicting postoperative delirium.Results:There were 74 cases in delirium group and 321 cases in non-delirium group, and the incidence of postoperative delirium was 18.7%. There were statistically significant differences in terms of age ≥70 yr, education level of junior high school and below, poor nutritional status, ASA Physical Status classification Ⅲ, postoperative admission to ICU, proportion of frailty and intraoperative bleeding volume between delirium group and non-delirium group ( P<0.05). The results of logistic regression analysis showed that age, educational level, nutritional status, ASA Physical Status classification, intraoperative bleeding and frailty were all independent risk factors for delirium ( P<0.05). The area under the receiver operating characteristic curve of preoperative frailty predicting postoperative delirium was 0.672 (95% confidence interval 0.605-0.740). Conclusions:Preoperative frailty is an independent risk factor for postoperative delirium in elderly patients undergoing noncardiac surgery, which can predict the occurrence of postoperative delirium to some extent.

Kawasaki disease ( KD) is an acute febrile illness that preferentially affects children youn-ger than 5 years old and the primary cause of acquired heart disease during childhood. Coronary artery aneu-rysms ( CAA) is a serious complication of KD, leading to ischemic heart disease, myocardial infarction, and sudden cardiac death. Timely initiation of treatment with intravenous immunoglobulin ( IVIG) has reduced the incidence of CAA from 25％ to 4％. Nitrogen-terminal B-type natriuretic peptide ( NT-proBNP ) , originally used for the management of adults with heart disease, was shown to be useful in the diagnosis and management of patients with KD. NT-proBNP is released by cardiomyocytes in response to mechanical factors, such as the dilation of cardiac chambers, and to pro-inflammatory cytokines. Patients with KD have higher NT-proBNP at the time of diagnosis than febrile controls. Moreover, patients with resistance to IVIG treatment and CAA were found to have higher levels of NT-proBNP, suggesting a prognostic role. This review summarizes the signifi-cance of NT-proBNP in the diagnostic value of KD in recent years.

Objective To explore the dynamic changes in brain natriuretic peptide (BNP) concentration and the diagnostic value of BNP for heart failure at different time points in the early phase of acute myocardial infarction (AMI). Methods AMI patients who were admitted in our department between January 1, 2016 and July 31, 2016 and underwent emergency percutaneous coronary intervention (PCI) within 12 h after onset were enrolled in this study. All the patients received bedside examinations of BNP concentration and clinical cardiac function within 1 h after PCI and at 12, 20, 24 and 48 h after the onset of AMI. According to the peak BNP concentration, the patients were divided into high peak BNP group (>400 pg/mL) and normal peak BNP group (≤400 pg/mL). Results Seventy patients were enrolled in the study. Within 48 h after AMI onset, BNP concentration variations followed a pattern of an initial increase till reaching the peak concentration at 20 to 24 h, with subsequent gradual decrease. BNP concentrations differed significantly among the indicated time points (χ2=141.7, P<0.05) except for those between 20 h and 24 h (χ2=0.173, P>0.05). Compared with those in normal peak BNP group, the patients in high peak BNP group had an older age, a lower BMI, a longer time to perfusion, and a higher likeliness of anterior myocardial infarction and pulmonary infection (P<0.05). Logistic regression analysis showed that age, BMI and anterior myocardial infarction were independently associated with the increase of peak BNP concentration. ROC curve analysis showed that BNP concentration within 1 h after emergency PCI was unable to diagnose heart failure at that time (P>0.05), while BNP concentrations at 12, 20, 24 and 48 h after AMI onset had significant diagnostic values for heart failure (P<0.05) with areas under ROC of 0.860, 0.786, 0.768 and 0.863, and optimal cutoff values of 156.5, 313.7, 240.9 and 285.9 pg/mL, respectively. Conclusions BNP concentration increases first and then decreases in the early phase of AMI, and the peak concentration occurs at 20-24 h after the onset. The diagnostic values of BNP concentrations at different time points also vary.

Objective To investigate the clinical efficacy and complications of minimally invasive transforaminal lumbar-interbody fusion (TLIF) in the treatment of lumbar spondylolisthesis. Methods Total 142 patients with single level spondylolis-thesis who treated by TLIF from 2010.01 to 2015.06 were included in this study, with 68 cases in minimally invasive TLIF (MIS-TLIF) group and 74 cases in traditional open TLIF group. The general information (age, gender, isthmic or degenerative type, per-centage of slip degree, levels), operative time, blood loss, length of postoperative hospital stay, Visual Analogue Scale (VAS) of low-back pain and leg pain, and Oswestry Disability Index (ODI) were recorded and collected. The posterior height of the interverte-bralpace and segmental lordosis, reduction of spondylolisthesis and cross-sectional area of spinal canal were measured. Results There was no statistically significant difference between the two groups in age, gender ratio, percentage of slip degree, and sur-gicallevels distribution. Total of 66 cases in MIS-TLIF group and 71 cases in Open TLIF group finished 2 years follow up, and 25 cases in MIS-TLIF group and 31 cases in Open TLIF group finished 5 years follow up. The blood loss of the MIS-TLIF group was 164.7±51.7 ml, significantly lower than the open TLIF group of 239±69.3 ml(P<0.001). The length of postoperative hospital stay was 5.9 ± 1.5 days in MIS-TLIF group, significantly shorter than the open TLIF group of 7.3 ± 3.1 days(P<0.001). The operative time of MIS-TLIF and Open TLIF was 146.3±21.9 mins, 152.0±20.4 mins, respectively, and no significant differ-ence was found between them. The VAS ofback pain, leg pain, ODI in MIS-TLIF group was 1.76±1.16, 1.91±1.36 and 23.5± 7.3 at 2 years follow up, and in Open TLIF was 1.73±1.10, 1.83±1.36 and 23.8±6.7, respectively, all of them were significant-ly different to pre-operation, however, no significant difference was found between two groups. The VAS of back pain, leg pain, ODI in MIS-TLIF group was 1.73±1.21, 1.93±1.48, and 25.4±6.8 at 5years follow up, and in Open TLIF was 1.85±1.02, 1.85± 1.33 and 26.1 ± 6.5, respectively, no significant difference between twogroups. The posterior height of the intervertebral space and segmental lordosis of MIS-TLIF was 9.52±1.67 mm and 12.11°±3.44° at 2 years follow up, while the open TLIF was 9.88± 1.54 mm and 12.98 ± 3.83° , all of them were significantly different to pre-operation,however, no significant difference between two groups. The posterior height of the intervertebral space and segmental lordosis of MIS-TLIF was 9.37 ± 1.46 mm and 11.55° ± 2.77° , while the open TLIF was 9.66 ± 1.68 mm and 12.59° ± 4.23° , no significant difference between two groups. The percentage of slip degree was reduced to 5.2％±4.6％ in MIS-TLIF and 5.6％±4.3％ in open TLIF, the cross-sectional area of spinal canal was enlarged to 139.7±19.5 mm2 and 141.7±20.7 mm2, no significant difference between two groups either. Con-clusion MIS-TLIF has less blood loss, shorter postoperative hospital stay than open TLIF, and similar clinical pain and function-al outcomes. MIS-TLIF is suggested to be a safe and effective choice in the treatment of lower grade lumbar spondylolisthesis (Grade II or less).
