Background Intrauterine growth restriction (IUGR) is closely associated with placental dysfunction. However, the effects of preconception co-exposure to β-cypermethrin (β-CYP) and emamectin benzoate (EMB) on fetal growth and placental function remain unclear. Objective To investigate the effects of prenatal exposure to β-CYP and EMB on embryonic development in female rats and to elucidate the mechanisms by which these substances cause IUGR from the perspectives of placental structure, progesterone synthesis, and mitochondrial autophagy. Methods Forty-eight specific pathogen-free (SPF) adult female Sprague-Dawley (SD) rats were randomly assigned to a control group, a β-CYP group, an EMB group, and a co-exposure group (n=12 per group). A whole-body dynamic inhalation exposure system was used to simulate greenhouse exposure. Rats in the control group were exposed to clean air, whereas those in the exposure groups were exposed to β-CYP (55 mg·m⁻³), EMB (7.8 mg·m⁻³), or their combination for 2 h per day for 90 consecutive days. After exposure, ovarian and serum estradiol (E₂) levels were determined in six rats from each group, while the remaining six rats were mated. Of the mated rats, three per group were sacrificed on gestational day 18, and the other remaining three were allowed to deliver naturally. Pregnancy outcomes and fetal development were evaluated. Placental morphology, progesterone (Prog) levels, progesterone synthesis-related factors, oxidative stress, mitochondrial function, and mitophagy-related indicators were subsequently assessed. Results Compared with the control group, fetal body weight on gestational day 18 and neonatal body weight were significantly decreased, whereas the incidence of IUGR was significantly increased in the β-CYP, EMB, and co-exposure groups (P<0.05). The EMB and co-exposure groups exhibited an increased proportion of the placental junctional zone thickness to total placental thickness and a reduced proportion of the labyrinth zone (P<0.05). Ovarian E₂ and placental Prog levels were decreased in all three exposure groups. In addition, the placental expression of cytochrome P450 family 11 subfamily A member1(CYP11A1)、3β-hydroxysteroid dehydrogenase type 1(HSD3B1)、progesterone receptor(PgR) was downregulated, catalase (CAT) activity and adenosine triphosphate (ATP) content were reduced, and lactate dehydrogenase (LDH) activity was increased in all exposure groups (P < 0.05). Furthermore, the expression of translocase of outer mitochondrial membrane 2 was decreased, whereas the expression levels of microtubule-associated protein 1 light chain 3 (LC3), PTEN-induced kinase 1 (PINK1), parkin RBR E3 ubiquitin-protein ligase (Parkin), and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) were increased in all exposure groups (P<0.05). Conclusion Prenatal exposure to β-CYP and EMB can cause structural damage to the rat placenta, affect the expression of markers related to progesterone synthesis, and is accompanied by oxidative stress, mitochondrial dysfunction, and alterations in PINK1/Parkin-mediated mitochondrial autophagy, ultimately affecting the intrauterine growth and development of the fetus.

Objective To evaluate the effect of multi-disciplinary team(MDT)management mode on the preven-tion and control of carbapenem-resistant Enterobacterales(CRE)infection after lung transplant surgery,and explore the influencing factors for CRE infection after lung transplant.Methods A total of 654 lung transplant recipients from Lung Transplant Center of Wuxi People's Hospital from January 2014 to July 2023 were selected as the re-search subjects.According to the time nodes of the implementation of MDT management mode,lung transplant re-cipients from January 2014 to December 2019 were assigned to the control group without implementation of MDT management mode.Lung transplant recipients from January 2020 to July 2023 were in the intervention group with MDT management mode implementation.Kaplan-Meier method was used to calculate the risk of CRE infection in lung transplant recipients 90 days after surgery.Cox regression model was used to adjust variables such as length of hospital stay,surgical duration,and catheterization days of three catheters,and the effect of implementing MDT management mode on the risk of CRE infection was analyzed.Results Among 654 lung transplant recipients,215 had healthcare-associated infection(HAI),including 158 cases from the control group and 57 from the intervention group,with HAI rates of 38.54％and 23.36％,respectively.The incidence of HAI in lung transplant recipients in the intervention group was lower than that in the control group(x2=15.965,P＜0.001).A total of 74 cases of CRE infection were confirmed,and CRE infection rate in the intervention group was lower than that in the control group(7.79％[19/244]vs 13.41％[55/410];x2=4.828,P=0.028).By the end of the 90-day follow-up period,the cumulative infection risks of the control group and intervention group were 14.67％and 8.26％,respectively,with a statistically significant difference between the two groups(P＜0.05).The implementation of MDT manage-ment mode was a protective factor for post-operative CRE infection in lung transplant recipients,while duration of surgery,duration of ventilator use,and duration of urinary catheterization were risk factors for CRE infection(all P＜0.05).Conclusion Implementing MDT management mode in lung transplant recipients can effectively reduce the risk of post-operative CRE infection.Continuously standardizing and implementing MDT management of multidrug-resistant organisms in hospitals is an important mean of preventing CRE infection and controlling transmission.

Objective To systematically evaluate the risk factors for new-onset atrial fibrillation after off-pump coronary artery bypass grafting (OPCABG). Methods PubMed, EMbase, The Cochrane Library, CNKI, Wanfang, VIP, SinoMed were searched to collect published literature on risk factors for new-onset atrial fibrillation after OPCABG from inception to September 2022. Two authors independently screened, extracted data and evaluated the quality. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the included studies, and Stata 12.0 and RevMan 5.4 softwares were used for meta-analysis. Results A total of 18 researches were included, including 6 354 patients of OPCABG. The NOS scores of the included studies were 6-8 points. Meta-analysis showed that age [MD=2.56, 95%CI (1.61, 3.52), P<0.001], hypertension [OR=1.77, 95%CI (1.18, 2.66), P<0.001], EuroSCORE Ⅱ score [MD=0.70, 95%CI (0.34, 1.06), P<0.001], frequent atrial premature beats or atrial tachycardia [OR=3.77, 95%CI (2.13, 6.68), P<0.001], left atrium diameter (LAD) [MD=1.64, 95%CI (0.26, 3.03), P=0.010], left ventricular ejection fraction (LVEF) [MD=−1.84, 95%CI (−2.85, −0.83), P<0.001], right coronary stenosis [OR=2.49, 95%CI (1.29, 4.81), P=0.006], three-vessel coronary artery lesions [OR=0.73, 95%CI (0.54, 0.97), P=0.030], not using β blockers [OR=0.81, 95%CI (0.69, 0.96), P=0.010], operation time [MD=10.13, 95%CI (8.15, 12.10), P<0.001], duration of mechanical ventilation [OR=2.85, 95%CI (1.79, 3.91), P<0.001] were risk factors for new-onset atrial fibrillation after OPCABG. Conclusion Advanced age, hypertension, high EuroSCOREⅡ score, frequent atrial premature beats or atrial tachycardia, increased LAD, decreased LVEF, right coronary stenosis, three-vessel coronary artery lesions, not using β blockers, prolonged operation time and mechanical ventilation are risk factors for new-onset atrial fibrillation after OPCABG. Due to factors such as the methodology, content and quality of the included literature, the conclusion of this study need to be supported by more high-quality studies.

Objective To evaluate the effectiveness of multi-disciplinary team (MDT) mode in the prevention and control of multidrug resistant organism (MDRO) infection in lung transplant recipients. Methods Lung transplant recipients admitted to the hospital from 2019 to 2022 were enrolled. MDT expert group was established in January, 2020. A series of prevention and control measures were conducted. The implementation rate of MDRO prevention and control measures and the detection rate of MDRO on the environmental surface from 2020 to 2022, and the detection rate of MDRO in lung transplant recipients from 2019 to 2022 were analyzed. Results The overall implementation rate of MDRO prevention and control measures for medical staff was increased from 64.9% in 2020 to 91.6% in 2022, showing an increasing trend year by year (P<0.05). The detection rate of MDRO on the environmental surface was decreased from 28% in 2020 to 9% in 2022, showing a downward trend year by year (P<0.05). The detection rate of MDRO in lung transplant recipients was decreased from 66.7% in 2019 to 44.3% in 2022, showing a decreasing trend year by year (P<0.001). Conclusions MDT mode management may enhance the implementation of MDRO prevention and control measures for medical staff, effectively reduce the infection rate of MDRO in lung transplant recipients and the detection rate of MDRO on the environmental surface, which is worthy of widespread application.

Objective:To investigate the effect of spinopelvic sagittal alignment and lordosis distribution index on adjacent segment degeneration (ASD) after short-segment lumbar interbody fusion.Methods:A total of 234 patients who underwent posterior lumbar interbody fusion due to lumbar degenerative diseases in the Affiliated Changzhou Second People's Hospital of Nanjing Medical University and Affiliated Drum Tower Hospital, Medical School of Nanjing University from January 2009 to January 2019 were retrospectively analyzed. There were 102 males and 132 females, aged 60.1±10.0 years (range, 41-78 years). The patients were divided into ASD group and non-ASD group according to whether ASD occurred after operation. The general data, pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), lumbar lordosis (LL), distal lordosis (DL), segmental lordosis (SL), lordosis distribution index (LDI) and sagittal vertical axis (SVA) before and after operation were compared between the two groups. Independent risk factors for the occurrence of ASD after lumbar fusion were analyzed using binary logistic regression. The receiver operating characteristic curve (ROC) was plotted, and the area under the curve was calculated for each independent risk factor.Results:All patients successfully completed the operation and were followed up for 70.6±11.9 months (range, 60-121 months). Among the 234 patients, 116 patients developed ASD after operation. Age ( t=2.697, P=0.008), fusion segment (χ 2=16.439, P<0.001), preoperative PT ( t=2.268, P=0.024), preoperative LL ( t=2.042, P=0.042), preoperative DL ( t=2.724, P=0.007), postoperative DL ( t=3.104, P=0.002), postoperative LDI ( t=2.063, P=0.040) and the difference of SVA before and after operation ( Z=2.001, P=0.045) were statistically significant. Binary logistic regression analysis showed that LDI decreased ( OR=0.971, P=0.002), two-level fusion ( OR=3.477, P<0.001), and increased SVA difference before and after operation ( OR=0.992, P=0.039) were independent risk factors for ASD after lumbar fusion. The ROC curve showed that the area under the curve and 95% CI of the number of fusion segments, postoperative LDI, and the difference of SVA before and after operation were 0.633 (0.561, 0.704), 0.583 (0.510, 0.656) and 0.576 (0.502, 0.649), respectively. The area under the curve of the combined prediction model was 0.702, and the prediction value was medium. Conclusion:Two-level fusion, decreased LDI after operation, and increased SVA difference before and after operation are independent risk factors for ASD after lumbar fusion, and the combined prediction of the three has good predictive efficiency.

Patients with acute heart failure (AHF) often experience dyspnea, and monitoring and quantifying their breathing patterns can provide reference information for disease and prognosis assessment. In this study, 39 AHF patients and 24 healthy subjects were included. Nighttime chest-abdominal respiratory signals were collected using wearable devices, and the differences in nocturnal breathing patterns between the two groups were quantitatively analyzed. Compared with the healthy group, the AHF group showed a higher mean breathing rate (BR_mean) [(21.03 ± 3.84) beat/min vs. (15.95 ± 3.08) beat/min, P < 0.001], and larger R_RSBI_cv [70.96% (54.34%-104.28)% vs. 58.48% (45.34%-65.95)%, P = 0.005], greater AB_ratio_cv [(22.52 ± 7.14)% vs. (17.10 ± 6.83)%, P = 0.004], and smaller SampEn (0.67 ± 0.37 vs. 1.01 ± 0.29, P < 0.001). Additionally, the mean inspiratory time (TI_mean) and expiration time (TE_mean) were shorter, TI_cv and TE_cv were greater. Furthermore, the LBI_cv was greater, while SD1 and SD2 on the Poincare plot were larger in the AHF group, all of which showed statistically significant differences. Logistic regression calibration revealed that the TI_mean reduction was a risk factor for AHF. The BR_ mean demonstrated the strongest ability to distinguish between the two groups, with an area under the curve (AUC) of 0.846. Parameters such as breathing period, amplitude, coordination, and nonlinear parameters effectively quantify abnormal breathing patterns in AHF patients. Specifically, the reduction in TI_mean serves as a risk factor for AHF, while the BR_mean distinguishes between the two groups. These findings have the potential to provide new information for the assessment of AHF patients.

Objective:To construct a biospecimen bank of patient derived organoids (PDOs) from pancreatic cancer tissues and to explore the feasibility of PDOs drug sensitivity assay technology to guide chemotherapy drug selection for pancreatic cancer.Methods:Pancreatic cancer tissue specimens obtained after surgical resection and puncture biopsy from Mar 2020 to Dec 2022 at Drum Tower Hospital, Nanjing University School of Medicine were collected. Pancreatic cancer PDOs were cultured in vitro and histologically identified; PDOs were treated with gemcitabine, Nab-paclitaxel, fluorouracil, Oxaliplatin, and Irinotecan and cell viability was measured to analyze the correlation between PDOs drug sensitivity and the actual clinical treatment response.Results:The PDOs can reproduce the pathological features of corresponding tumor tissues; the sensitivity of different PDOs to the same chemotherapeutic drug is significantly different; The sensitivity of PDOs was highly consistent with the actual treatment effect of the corresponding patients 75.76% (25/33); organoid organ-based susceptibility testing had predictive value for the treatment response of patients (AUC=0.733, 95% CI: 0.546-0.919, P<0.05). Conclusion:A biobank of pancreatic cancer PDOs was successfully constructed, and the drug susceptibility test results were significantly correlated with the actual medication response of patients, suggesting that the drug susceptibility test technology based on PDOs has the potential to guide individualized chemotherapy for pancreatic cancer.
