Purpose To explore the clinical value of screening for partial agenesis of the corpus callosum(PACC)via measuring the distance from the end of the fetal corpus callosum to the occipital bone.Materials and Methods A Prospective study were performed from October 2017 to April 2023 in Ji’an Maternal and Child Health Care Hospital and Jiangxi Maternal and Child Health Hospital.A total of 33 PACC fetuses(abnormal group)and 396 normal fetuses(normal group)were selected as the research subjects.The distance(Z value)from the terminal posterior edge of the corpus callosum to the occipital bone was measured,Z value was calculated and compared between groups.The truncation value and related diagnostic efficiency indexes were calculated by receiver operator characteristic curve analysis,and the positive rate of Z value of abnormal group was compared with that of indirect signs.Results The distance from the terminal posterior edge of the corpus callosum to the occipital bone was positively correlated with the gestational age(r=0.913,P<0.001).The best regression equation was that the distance from the terminal posterior edge of the corpus callosum to the occipital bone was 3.879+1.115×gestational age,and the standard deviation was 1.670.The results of mean comparison showed that the Z value of the abnormal group was significantly higher than that of the normal group(t=11.223 9,P<0.001).When Z value 2.199 7 was used as the cut-off value for the diagnosis of PACC,the area under the curve was 0.9981,the Yoden index was 0.959 6,and the sensitivity,specificity,positive and negative predictive values were 96.97%,98.99%,88.89%and 99.75%,respectively.The positive rate of Z value in abnormal group was significantly higher than that of indirect signs(96.97%vs.63.64%,χ2=7.692 3,P<0.01).Conclusion The distance from the terminal posterior edge of corpus callosum to the occipital bone of PACC fetus is larger than that of normal fetus.The increase of Z value indicates that the end of corpus callosum moves forward,which can be used as one of the basis for screening PACC,and it has high clinical value when Z value 2.199 7 is used as the cut-off value for PACC screening.

Objective:To investigate the molecular markers involved in death related to acute myocardial infarction (AMI) and provide new targets for early intervention.Methods:Consecutive patients who hospitalized in department of cardiology, Xuanwu Hospital, Capital Medical University from January 2017 to December 2021 and diagnosed with AMI were enrolled. The clinical factors and markers associated with in-hospital death after AMI were analyzed. In addition, patients diagnosed with AMI hospitalized in department of cardiology, Xuanwu Hospital, Capital Medical University from September 2022 to April 2023 were enrolled. We prospectively analyzed the plasma protein of death related to AMI via Olink Precision Proteomics based on proximity extension assay (PEA) technology.Results:In the retrospective study, 2 325 patients with AMI were analyzed, including 75 patients in the in-hospital death group and 2 250 subjects in the survival group. The overall mortality rate during hospitalization was 3.23% (75/2325). The patients in the death group were older: 72 (64, 80) years vs. 63 (55, 71) years. And Interleukin-6 (IL-6), hypersensitive C-reactive protein (Hs-CRP), leukocyte counts and neutrophil counts were markedly higher in the death group than those in the survival group: 69.0 (26.7, 136.6) ng/L vs. 18.2 (9.4, 36.5) ng/L, 45.7 (28.7, 50.5) mg/L vs. 5.5 (2.0, 17.2) mg/L, 12.0 (9.8, 14.1) ×10 9/L vs. 8.9 (7.2, 11.2) × 10 9/L, 9.8 (7.8, 12.1) ×10 9/L vs. 6.5(4.7, 8.8) ×10 9/L ( P<0.01). In this prospective study, 86 patients with AMI were analyzed. 61 proteins including Insulin-like growth factor-binding protein 1, 2 (IGFBP-1, IGFBP-2), Chitotriosidase-1 (CHIT1), Complement component C1q receptor (CD93) were independently associated with in-hospital death related to AMI ( P<0.05). The differential proteins were mainly enriched in inflammatory response, cell adhesion, cytokine signaling pathway and apoptosis. Moreover, 22 proteins including Urokinase plasminogen activator surface receptor (U-PAR), Trefoil factor 3 (TFF3), Perlecan (PLC), Growth differentiation factor 15 (GDF-15), Junctional adhesion molecule A (JAM-A) were plotted according to a logistic regression model, and the area under the curve (AUC) was more than 0.9, showing the high accuracy in predicting in-hospital death after AMI. Conclusions:Molecular markers of the inflammatory response, cell adhesion, cell growth and apoptosis might be involved in death related to AMI, which provides new targets for early intervention.

Objective:To investigate the correlation of neutrophil-to-albumin ratio (NAR) and glucose-to-lymphocyte ratio (GLR) with in-hospital death in patients with acute myocardial infarction (AMI).Methods:The clinical data of 2 657 patients with AMI from January 2017 to December 2022 in Xuanwu Hospital, Capital Medical University were retrospectively analyzed. Using receiver operating characteristic (ROC) curve to determine the optimal cutoff values of GLR and NAR (6.02 and 0.25) for predicting in-hospital mortality in patients with AMI, the patients were divided into high GLR group (GLR≥6.02, 768 cases) and low GLR group (GLR<6.02, 1 889 cases), high NAR group (NAR≥0.25, 547 cases) and low NAR group (NAR<0.25, 2 110 cases) according the optimal cutoff values. The baseline characteristics and occurrence of in-hospital major adverse cardiovascular events (MACE) were recorded. Multivariate Logistic regression was used to analyze the independent risk factors for in-hospital death in patients with AMI.Results:Among the 2 657 patients with AMI, 265 patients had in-hospital MACE (10.0%), and 50 patients (1.9%) died. The age, proportion of Killip≥ 2 grade, proportion of diabetes, proportion of myocardial infarction, proportion of cerebral infarction history, proportion of ST-elevation myocardial infarction (STEMI), thrombolysis in myocardial infarction clinical trial score (TIMI score), global registry of acute coronary event score (GRACE score), fibrinogen, fasting blood glucose, glycated hemoglobin, high-density lipoprotein cholesterol (HDL-C), cardiac troponin I (cTnI) peak, N-terminal B-type natriuretic peptide (NT-proBNP), hypersensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), NAR, GLR, neutrophil count, left ventricular end-diastolic diameter (LVEDD) in high GLR group were significantly higher than those in low GLR group, the proportion of males, body mass index (BMI), proportion of smoking history, proportion of non-ST elevation myocardial infarction (NSTEMI), albumin, estimated glomerular filtration rate (eGFR), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), lymphocyte count, monocyte count and left ventricular ejection fraction (LVEF) were significantly lower than those in low GLR group, and there were statistical differences ( P<0.01 or <0.05). The proportion of Killip≥2 grade, proportion of STEMI, TIMI score, GRACE score, fibrinogen, fasting blood glucose, TC, LDL-C, cTnI peak, hs-CRP, IL-6, NAR, GLR, white blood cell count, neutrophil count and monocyte count in high NAR group were significantly higher than those in low NAR group, the age, proportion of myocardial infarction history, proportion of NSTEMI, albumin, lymphocyte count, left atrial diameter (LAD) and LVEF were significantly lower than those in low NAR group, and there were statistical differences ( P<0.01 or <0.05). The incidences of in-hospital MACE, death, ventricular fibrillation or pulseless ventricular tachycardia, atrial fibrillation, cardiac arrest and bleeding in high GLR group were significant higher than those in low GLR group: 15.2% (117/768) vs. 7.8% (148/1 889), 4.6% (35/768) vs. 0.8% (15/1 889), 5.3% (41/768) vs. 2.9% (54/1 889), 6.9% (53/768) vs. 4.0% (75/1 889), 4.7% (36/768) vs. 1.4% (26/1 889) and 2.3% (18/768) vs. 0.7% (13/1 889), and there were statistical differences ( P<0.01); there was no statistical difference in the incidence of heart rupture between two groups ( P>0.05). The incidence of in-hospital MACE, death, ventricular fibrillation or pulseless ventricular tachycardia, cardiac arrest, cardiac rupture and bleeding in high NAR group were significantly higher than those in low NAR group: 16.6% (91/547) vs. 8.2% (174/2 110), 5.9% (32/547) vs. 0.9% (18/2 110), 8.0% (44/547) vs. 2.4% (51/2 110), 5.9% (32/547) vs. 1.4% (30/2 110), 1.6% (9/547) vs. 0.4% (9/2 110) and 2.4% (13/547) vs. 0.9% (18/2 110), and there were statistical differences ( P<0.01); there was no statistical difference in the incidence of atrial fibrillation between two groups ( P>0.05). Multivariate Logistic regression analysis result showed that the Killip 3 and 4 grades, high NAR, high GRACE score, high fasting glucose and low LVEF were independent risk factors for in-hospital death in patients with AMI ( OR = 3.827, 4.660, 3.779, 1.020, 1.095 and 0.962; 95% CI 1.158 to 12.649, 1.184 to 18.344, 1.856 to 7.649, 1.009 to 1.032, 1.027 to 1.167 and 0.932 to 0.993; P<0.05 or <0.01). Conclusions:The NAR can independently predict the risk of in-hospital death in patients with AMI.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Purpose To explore the clinical value of screening for partial agenesis of the corpus callosum(PACC)via measuring the distance from the end of the fetal corpus callosum to the occipital bone.Materials and Methods A Prospective study were performed from October 2017 to April 2023 in Ji’an Maternal and Child Health Care Hospital and Jiangxi Maternal and Child Health Hospital.A total of 33 PACC fetuses(abnormal group)and 396 normal fetuses(normal group)were selected as the research subjects.The distance(Z value)from the terminal posterior edge of the corpus callosum to the occipital bone was measured,Z value was calculated and compared between groups.The truncation value and related diagnostic efficiency indexes were calculated by receiver operator characteristic curve analysis,and the positive rate of Z value of abnormal group was compared with that of indirect signs.Results The distance from the terminal posterior edge of the corpus callosum to the occipital bone was positively correlated with the gestational age(r=0.913,P<0.001).The best regression equation was that the distance from the terminal posterior edge of the corpus callosum to the occipital bone was 3.879+1.115×gestational age,and the standard deviation was 1.670.The results of mean comparison showed that the Z value of the abnormal group was significantly higher than that of the normal group(t=11.223 9,P<0.001).When Z value 2.199 7 was used as the cut-off value for the diagnosis of PACC,the area under the curve was 0.9981,the Yoden index was 0.959 6,and the sensitivity,specificity,positive and negative predictive values were 96.97%,98.99%,88.89%and 99.75%,respectively.The positive rate of Z value in abnormal group was significantly higher than that of indirect signs(96.97%vs.63.64%,χ2=7.692 3,P<0.01).Conclusion The distance from the terminal posterior edge of corpus callosum to the occipital bone of PACC fetus is larger than that of normal fetus.The increase of Z value indicates that the end of corpus callosum moves forward,which can be used as one of the basis for screening PACC,and it has high clinical value when Z value 2.199 7 is used as the cut-off value for PACC screening.

Objective:To analyze the risk factors for postoperative cardiovascular events (PCE) after renal transplantation and their impact on transplant kidney function.Methods:The clinical data of 120 patients who underwent kidney transplant at Xuanwu Hospital, Capital Medical University from March 2020 to March 2022 were retrospectively analyzed. Among them, 23 cases occurred PCE (PCE group), and 97 cases did not occur PCE (non-PCE group). The relevant preoperative and postoperative data were recorded. Multivariate Logistic regression was used to analyze the independent risk factors of PCE in kidney transplant patients.Results:The incidence rate of PCE in kidney transplant patients was 19.17% (23/120). There were no statistical differences in the gender composition, preoperative dyslipidemia rate, preoperative hypertension rate and immunosuppressant use between two groups ( P>0.05); the age, preoperative body mass index>30 kg/m 2 rate, preoperative dialysis time>12 months rate, preoperative diabetes rate, preoperative cardiovascular disease rate, preoperative diabetic nephropathy rate, cadaver kidney transplant rate, postoperative dyslipidemia rate, postoperative serum creatinine >200 μmol/L rate, postoperative new-onset diabetes rate, postoperative delayed failure rate and postoperative acute reaction rate in PCE group were significantly higher than those in non-PCE group, and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis showed that age, preoperative diabetes, preoperative cardiovascular disease, preoperative diabetic nephropathy, postoperative serum creatinine >200 μmol/L and postoperative acute reaction were independent risk factors of PCE in kidney transplant patients ( OR = 2.40, 3.42, 3.85, 1.98, 2.62 and 2.11; 95% CI 1.67 to 3.58, 1.61 to 7.05, 2.61 to 5.55, 1.05 to 3.85, 1.25 to 4.52 and 1.20 to 4.78; P<0.01 or <0.05). There was no statistically significant difference in serum creatinine 3 months after surgery between two groups ( P>0.05); the serum creatinine 6 and 12 months after surgery in PCE group was significantly higher than that in non-PCE group: (139.58 ± 31.54) μmol/L vs. (105.36 ± 21.05) μmol/L and (198.32 ± 40.12) μmol/L vs. (107.63 ± 24.64) μmol/L, and there were statistical differences ( P<0.01). Conclusions:The incidence of PCE in kidney transplant patients is higher, and there are many risk factors for PCE. If relevant measures are taken to correct or remove risk factors, it may reduce the incidence of PCE and prolong survival time in kidney transplant patients.

Objective:To investigate the relationship between body mass index (BMI) and gestational hypertension using two-sample Mendelian randomization analysis.Methods:The summary level data for BMI and gestational hypertension were obtained from the genome-wide association study (the deadline for data inclusion was October 31, 2023). All data were analyzed by inverse variance weighting, MR-Egger regression, weighted median, simple model and weighted model methods. Cochrane Q test was used to evaluate heterogeneity, MR-Egger regression intercept test and funnel plot were used to assess horizontal pleiotropy. Results:Inverse variance weighting result under fixed effects and random effects models showed that the risk of gestational hypertension increased with the increase of BMI ( OR = 1.62 and 1.62, 95% CI 1.39 to 1.88 and 1.39 to 1.88, P<0.01). Sensitivity analysis results including MR-Egger regression, weighted median and weighted model methods showed that BMI increased the risk of gestational hypertension ( OR = 1.51, 1.56 and 1.71; 95% CI 1.01 to 2.26, 1.23 to 1.99 and 1.09 to 2.69; P<0.05 or <0.01). Although Cochrane Q test result showed evidence of heterogeneity ( P = 0.04), inverse variance weighting under a random model suggested that BMI increased the risk of gestational hypertension. Horizontal pleiotropy was not observed in the above analysis ( P = 0.73). Conclusions:Obesity may increase the risk of gestational hypertension. Pregnant women should pay attention to weight control to decrease the risk of gestational hypertension.

The polyfoliate perforator flap is a new type of flap that was developed on the basis of the traditional polyfoliate myocutaneous flap, polyfoliate fascial flap and perforator flap. It overturns the traditional idea that the deep fascial vascular network is the fundamental for a survival of the flap, and enables the flaps to achieve the best profile and function of the recipient areas with minimal damage to the donor area. In order to improve the understanding of the polyfoliate perforator flap and further standardise its clinical application, this paper forms a consensus on the definition, classification, indications, operative points and precautions of the polyfoliate perforator flap, so as to provide references in diagnosis and treatment process and practical application for the surgeons.
