Methods We searched the CNKI, SinoMed, Wanfang data, VIP, PubMed, Web of Science, EMbase, The Cochrane Library database from inception to September 2022. Case-control studies, and cohort studies on risk factors for postoperative delirium after surgery for Stanford type A aortic dissection were collected to identify studies about the risk factors for postoperative delirium after surgery for Stanford type A aortic dissection. Quality of the included studies was evaluated by the Newcastle-Ottawa scale (NOS). The meta-analysis was performed by RevMan 5.3 software and Stata 15.0 software. Results A total of 21 studies were included involving 3385 patients. The NOS score was 7-8 points. The results of meta-analysis showed that age (MD=2.58, 95%CI 1.44 to 3.72, P＜0.000 01), male (OR=1.33, 95%CI 1.12 to 1.59, P=0.001), drinking history (OR=1.45, 95%CI 1.04 to 2.04, P=0.03), diabetes history (OR=1.44, 95%CI 1.12 to 1.85, P=0.005), preoperative leukocytes (MD=1.17, 95%CI 0.57 to 1.77), P=0.000 1), operation time (MD=21.82, 95%CI 5.84 to 37.80, P=0.007), deep hypothermic circulatory arrest (DHCA) time (MD=3.02, 95%CI 1.04 to 5.01, P=0.003), aortic occlusion time (MD=8.94, 95%CI 2.91 to 14.97, P=0.004), cardiopulmonary bypass time (MD=13.92, 95%CI 5.92 to 21.91, P=0.0006), ICU stay (MD=2.77, 95%CI 1.55 to 3.99, P＜0.000 01), hospital stay (MD=3.46, 95%CI 2.03 to 4.89, P＜0.0001), APACHEⅡ score (MD=2.76, 95%CI 1.59 to 3.93, P＜0.000 01), ventilation support time (MD=6.10, 95%CI 3.48 to 8.72, P＜0.000 01), hypoxemia (OR=2.32, 95%CI 1.40 to 3.82, P=0.001), the minimum postoperative oxygenation index (MD=−79.52, 95%CI −125.80 to −33.24, P=0.000 8), blood oxygen saturation (MD=−3.50, 95%CI −4.49 to −2.51, P＜0.000 01), postoperative hemoglobin (MD=−6.35, 95%CI −9.21 to −3.50, P＜0.000 1), postoperative blood lactate (MD=0.45, 95%CI 0.15 to 0.75, P=0.004), postoperative electrolyte abnormalities (OR=5.94, 95%CI 3.50 to 10.09, P＜0.000 01), acute kidney injury (OR=1.92, 95%CI 1.34 to 2.75, P=0.000 4) and postoperative body temperature (MD=0.79, 95%CI 0.69 to 0.88, P＜0.000 01) were associated with postoperative delirium after surgery for Stanford type A aortic dissection. Conclusion The current evidence shows that age, male, drinking history, diabetes history, operation time, DHCA time, aortic occlusion time, cardiopulmonary bypass time, ICU stay, hospital stay, APACHEⅡ score, ventilation support time, hypoxemia and postoperative body temperature are risk factors for the postoperative delirium after surgery for Stanford type A aortic dissection. Oxygenation index, oxygen saturation, and hemoglobin number are protective factors for delirium after Stanford type A aortic dissection.

Background::Psychological stress has been reported to be a potential risk factor for hypertension among females, but it remains unclear whether spousal chronic stress levels alter the risk of hypertension among women. We examined the associations between stress within the family and hypertension among married women.Methods::Reproductive-aged women who were planning for pregnancy and their husbands were recruited from the National Free Pre-pregnancy Checkup Projects (NFPCP) across 31 provinces in China in 2016 and 2017. Perceived stress of wives or husbands was measured with a 5-point Likert-type scale, and assessed from three domains: work/life-related stress, economic stress, and overall stress. Multivariable-adjusted logistic regression models were used to assess the associations between stress status and the prevalence of hypertension.Results::Of 10,027,644 couples, 261,098 (2.60%) women had hypertension. The results showed that higher stress levels among themselves or their husbands were associated with a higher prevalence of hypertension in women ( Pfor trend <0.001). Compared with non-stressed participants, female participants with the highest stress themselves were at a greater risk of hypertension, with adjusted odds ratio (OR) of 1.31 (95% confidence interval [CI]: 1.25-1.37); and compared with participants whose husbands had no stress, those whose husbands had the highest stress level were at a higher risk of hypertension with adjusted OR of 1.24 (95% CI: 1.20-1.29). Moreover, compared with non-stressed status for both couples, only-wife-stressed, only-husband-stressed, and both-stressed couples were found to be significantly associated with increased risks of wives’ hypertension, with adjusted ORs of 1.28 (95% CI: 1.25-1.31), 1.19 (95% CI: 1.17-1.21), and 1.28 (95% CI: 1.26-1.31), respectively. Conclusion::Moderate to severe stress in both spouses might be associated with female hypertension prevalence, which highlights the importance of paying attention to the psychological stresses of couples within the family.

Objective·To verify the performance and explore the clinical application value of a multi-modal pulmonary nodule diagnosis model combined with metabolic fingerprints,protein biomarker CEA and Image-AI via random forest(MPI-RF).Methods·This study enrolled 289 patients with pulmonary nodules who were admitted to the Shanghai Chest Hospital,Shanghai Jiao Tong University School of Medicine and were detected by low-dose helical computed tomography(LDCT).The patients were divided into malignant nodule group(n=197)and benign nodule group(n=92)based on postoperative pathological results,and the basic information of the two groups was collected and compared.Electrochemiluminescence was used to detect the preoperative serum CEA levels of the patients in the two groups,matrix-assisted laser desorption/ionization mass spectrometry(MALDI-MS)was used to detect the serum metabolic fingerprints,and the CT image artificial intelligence model Image-AI was used to calculate the image scores.CEA data,serum metabolic fingerprints data and image scores were integrated and input into MPI-RF to calculate the malignant probability score of each patient.The receiver operator characteristic curve(ROC curve)and area under the curve(AUC)were used to evaluate the performance of different models,and the DeLong test was used for comparative analysis,including the diagnostic performance of MPI-RF in different types(solid nodule,pure ground-glass nodule and part-solid nodule)and sizes(diameter<8 mm and diameter≥8 mm)of pulmonary nodules,the diagnostic performance comparison of MPI-RF with Mayo Clinic model,veterans administration(VA)model and Brock model,and the diagnostic performance comparison of MPI-RF with lung imaging reporting and data system(Lung-RADS)in benign and malignant nodules.Results·MPI-RF had good diagnostic performance in the differentiation of benign and malignant pulmonary nodules(AUC=0.887,95%CI 0.848?0.925,sensitivity 81.22%,specificity 83.70%).Among them,the AUC of MPI-RF for solid nodules was 0.877(95%CI 0.820?0.934),for part-solid nodules was 0.858(95%CI 0.771?0.946),and for pure ground-glass nodules was 0.978(95%CI 0.923?1.000).The AUC of MPI-RF was 0.840(95%CI 0.716?0.963)for nodules within 8 mm diameter and 0.891(95%CI 0.849?0.933)for nodules larger than 8 mm diameter.Compared with the existing models,the diagnostic performance of MPI-RF was better than that of Mayo Clinic model,VA model and Brock model(all P=0.000).Compared with Lung-RADS,MPI-RF had better diagnostic performance in the total samples and different types of nodules(all P=0.000).Conclusion·MPI-RF is a model for the differential diagnosis of benign and malignant pulmonary nodules with excellent performance,and has potential clinical application value.

Objective:To investigate the tissue methylation features of adenocarcinoma patients presenting as pulmonary nodules on CT scans.Methods:A retrospective analysis was conducted on 70 adenocarcinoma patients with pulmonary nodules diagnosed at the Shanghai General Hospital from June 1, 2022 to January 20, 2024. Participants were assigned to two groups using the random number table, with 40 in the discovery group and 30 in the validation group. In the discovery group, tissue samples were analyzed using reduced representation bisulfite sequencing (RRBS) technology to compare the average methylation levels between cancer tissues and paired adjacent non-cancerous tissues. Differentially methylated regions (DMRs) were screened for analysis of their distribution across various genomic functional elements, and hierarchical clustering was plotted. GO and KEGG pathway enrichment analyses were further conducted on the DMRs. Subsequently, candidate DMRs associated with lung adenocarcinoma were validated using TCGA lung adenocarcinoma cohort and targeted bisulfite sequencing technology in the validation group. The comparison of methylation levels between groups was conducted using t-tests or non-parametric tests, while rates and composition ratios were analyzed using chi-square tests or Fisher′s exact test.Results:In discovery cohort, the average methylation level in cancer tissues was lower compared to adjacent normal tissues [(42.369±4.627) vs (44.370±4.046), t=?2.059, P=0.043]. A total of 37 995 DMRs were identified, including 16 889 upregulated regions and 21 106 downregulated regions, predominantly locating in promoter regions (48.917%), introns (36.457%), and exons (10.812%). The DMR clustering heatmap revealed two distinct clusters corresponding to cancer tissues and adjacent non-cancerous tissues. GO analysis showed that DMRs associated genes were mainly located in the cell membrane and nuclear chromatin, and were primarily involved in RNA polymerase Ⅱ-related transcription and regulation. KEGG pathway enrichment analysis indicated that DMRs associated genes were mainly involved in neuroactive ligand-receptor interaction, cancer pathways, calcium signaling pathway, cAMP signaling pathway, and MAPK signaling pathway. Validation in the TCGA cohort confirmed 11 potential characteristic DMRs. In the validation group, TBS confirmed that the methylation levels of DMRs associated with MIR10B, DMRTA2, HOPX, TFAP2B and MARCH11 in cancer tissues were significantly higher than those in adjacent non-cancerous tissues [11.200(4.305, 27.088) vs 2.650(1.298, 4.645), Z=?4.539, P<0.05; 18.610(13.600, 33.025) vs 8.675(5.488, 13.085), Z=?4.554, P<0.05; 17.600(2.183, 76.015) vs 1.085(0.898, 1.835), Z=?5.131, P<0.05; 5.250(3.220, 7.693) vs 3.495(2.165, 4.383), Z=?2.861, P<0.05; 11.515(7.525, 21.033) vs 7.830(5.518, 11.488), Z=?2.440, P<0.05 ], and the differences were statistically significant. Conclusions:Lung adenocarcinoma tissue exhibits different methylation patterns compared with adjacent normal lung tissue. The identified DMRs are involved in the regulation of several key pathways. Results from the TCGA cohort and an independent validation group support the potential diagnostic value of DMRs such as MIR10B, DMRTA2, HOPX, TFAP2B, and MARCH11 in lung adenocarcinoma, though their clinical application requires further validation.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of three children with Menkes disease. METHODS: Three children who had presented at the Children's Medical Center, the Affiliated Hospital of Guangdong Medical University from January 2020 to July 2022 were selected as the study subjects. Clinical data of the children were reviewed. Genomic DNA was extracted from peripheral blood samples of the children, their parents and sister of child 1. Whole exome sequencing (WES) was carried out. Candidate variants were verified by Sanger sequencing, copy number variation sequencing (CNV-seq), and bioinformatic analysis. RESULTS: Child 1 was a 1-year-and-4-month male, and children 2 and 3 were monozygotic twin males aged 1-year-and-10-month. The clinical manifestations of the three children have included developmental delay and seizures. WES showed that child 1 has harbored a c.3294+1G>A variant of the ATP7A gene. Sanger sequencing confirmed that his parents and sister did not carry the same variant, suggesting that it was de novo. Children 2 and 3 had carried a c.77266650_77267178del copy number variation. CNV-seq results showed that their mother has carried the same variant. By searching the HGMD, OMIM and ClinVar databases, the c.3294+1G>A was known to be pathogenic. No carrier frequency has been recorded in the 1000 Genomes, ESP, ExAC and gnomAD databases. Based on the Standards and Guidelines for the Interpretation of Sequence Variants: A Joint Consensus Recommendation of the American College of Medical Genetics and Genomics (ACMG), the ATP7A gene c.3294+1G>A variant was predicted to be pathogenic. The c.77266650_77267178del variant has involved exons 8 to 9 of the ATP7A gene. ClinGen online system score for it was 1.8, which was also considered to be pathogenic. CONCLUSION The c.3294+1G>A and c.77266650_ 77267178del variants of the ATP7A gene probably underlay the Menkes disease in the three children. Above finding has enriched the mutational spectrum of Menkes disease and provided a basis for clinical diagnosis and genetic counseling.

Objective:To investigate the influence of pre-pregnancy body mass index (BMI), gestational weight gain and early feeding behavior on delayed onset of lactogenesis stage Ⅱ(DOL Ⅱ).Methods:This was a prospective study involving puerperae from Women's Hospital of Nanjing Medical University from March 2020 to June 2020. Demographic data and delivery data were obtained using questionnaires and breastfeeding behavior and milk secretion were followed up every day after delivery. According to whether the lactation initiation was longer than 72 h or not, all subjects were divided into DOL Ⅱ group or non-DOL Ⅱ group. Differences in general condition and breastfeeding between the two groups were compared using independent sample t-test, Chi-square test, and Mann-Whitney U test. Multivariate logistic regression analysis was used to analyze the risk factors of DOL Ⅱ. Results:During the study period, a total of 390 cases were enrolled and 334 cases among them were analyzed due to lost of follow-up in 56 cases. The incidence of DOL Ⅱ was 19.2% (64/334). Univariate analysis showed that body mass index [lean:18.8% (12/64) vs 13.3% (36/270); fit:56.2% (36/64) vs 74.8% (202/270); overweight: 25.0% (16/64) vs 11.9% (32/270); χ2=9.78], mode of delivery [vaginal delivery: 37.5% (24/64) vs 52.6% (142/270); cesarean section: 62.5% (40/64) vs 47.4% (128/270); χ2=4.71], nipple type score in LATCH score [2.0 (1.0-2.0) vs 2.0 (2.0-2.0), U=－2.08], frequency of breastfeeding in 24 h [(6.3±3.0) vs (8.3±3.6) times per day, t=－3.94], adding formula within 24 h [71.9% (46/64) vs 56.3% (152/270), χ2=5.20] and the proportion of attending breastfeeding clinic during pregnancy [73.4% (47/64) vs 85.6% (231/270), χ2=5.44] were significantly different between the DOL Ⅱ and non-DOL Ⅱ groups (all P<0.05). Multivariate logistic regression analysis showed that pre-pregnancy overweight was an independent risk factor for DOL Ⅱ ( OR=2.240, 95% CI:1.020-4.918, P=0.044), either was pre-pregnancy overweight with appropriate gestational weight gain ( OR=5.595, 95% CI:1.492-20.985, P=0.011), while breastfeeding frequency within 24 h ( OR=0.867, 95% CI: 0.780-0.963, P=0.008) and attending breastfeeding clinic during pregnancy ( OR=0.377, 95% CI: 0.173-0.820, P=0.014) were independent protective factors for DOL Ⅱ. Conclusions:Women who were overweight before pregnancy are more likely to suffer from DOL Ⅱ. Extra guidance should be given to this population during early breastfeeding. Attending prenatal breastfeeding consultation and increasing the frequency of breastfeeding in the early postpartum period may prevent DOL.

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 investigate the correlation of red blood cell distribution width-to-platelet ratio (RPR) with clinical features and prognosis of patients with multiple myeloma (MM).Methods:The clinical data of 137 patients with MM who were admitted to the Affiliated Hospital of Xuzhou Medical University from April 2013 to July 2019 were collected. The receiver operating characteristic (ROC) curve was used to determine the best cut-off value of RPR. According to the best cut-off value of RPR, the patients were divided into high RPR group and low RPR group, and the differences in clinical characteristics and prognosis between the two groups were analyzed.Results:The best cut-off value of RPR was 0.10, and according to the best cut-off value, the patients were divided into high RPR group (RPR ≥ 0.10, 52 cases) and low RPR group (RPR < 0.10, 85 cases). There were statistical differences between the high RPR group and low RPR group in the proportion of patients between different stratification of Durie-Salmon (DS) staging ( χ2 = 17.110, P < 0.01), International Staging System (ISS) staging ( χ2 = 10.817, P = 0.001), red blood cell distribution width standard deviation(RDW-SD) ( χ2 = 26.937, P < 0.01), hemoglobin ( χ2 = 17.140, P < 0.01), lactate dehydrogenase (LDH) ( χ2 = 7.926, P = 0.005), erythrocyte sedimentation rate (ESR) ( χ2 = 9.513, P = 0.002), β 2-microglobulin (β 2-MG) ( χ2 = 7.726, P = 0.005), and bone marrow plasma cell ratio (BMPC) ( χ2 = 6.621, P = 0.010). The overall response rate (ORR) in the low RPR group was higher than that in the high RPR group [82.4% (70/85) vs. 71.2% (37/52)], but the difference was not statistically significant ( χ2 = 2.366, P = 0.124). The deep remission rate in the low RPR group was higher than that in the high RPR group [56.5% (48/85) vs. 19.2% (10/52)], and the difference was statistically significant ( χ2 = 18.327, P < 0.01). The results of multivariate analysis showed that the albumin, RPR and degree of remission were independent influencing factors for the overall survival (OS) of newly treated MM patients (all P < 0.05). Conclusion:MM patients with elevated peripheral blood RPR have shorter OS time, and RPR may be one of the indicators for evaluating the prognosis of MM.

【Objective】 To investigate the hepatitis E virus(HEV) infection among voluntary blood donors in Liuzhou, Guangxi. 【Methods】 Qualified blood donations in Liuzhou from October to November 2019 were tested for anti-HEV IgG and IgM and.HEV antigen. HEV RNA test was performed on samples positive for HEV antigen and/or anti-HEV IgM. and the test results were analyzed statistically. 【Results】 The seroprevalence rates of HEV antigen and anti-HEV IgG and IgM among 5 751 qualified donations were 0, 26.03% (1497/5 751), and 1.67% (96/5 751), respectively.None of the 91 anti-HEV IgM positive samples was positive for HEV RNA, whereas 60.41% of anti-HEV IgM positive samples were anti-HEV IgG positive. The HEV antibody prevalence varied significantly by gender, age, and nationality (P<0.05). 【Conclusion】 The prevalence of anti-HEV IgG / IgM among blood donors in Liuzhou was higher than that in other domestic regions. Significant increase in HEV antibody prevalence was observed among ethnic minorities, such as Miao and Dong, and age group of more than 45 years.Follow-up studies with larger sample size could be conducted to estimate potential risks of HEV transmission by blood transfusion, which may provide references for selective screening of HEV infection marker among high-endemic population.

Objective:To explore the application of psychological resilience intervention combined with prospective nursing in patients with free skin flap transplantation to repair skin and soft tissue defects of extremities.Methods:Using the convenient sampling method, a total of 65 patients with soft tissue injury in the skin of extremities after undergoing free skin flap transplantation who were admitted to Henan Provincial People's Hospital from October 2019 to October 2020 were selected. According to the admission time, they were divided into the observation group (34 cases) and the control group (31 cases) . Patients in the observation group received psychological resilience intervention combined with prospective nursing, while patients in the control group only received prospective nursing. The surgical success rate, flap necrosis rate, incidence of vascular crisis and complications were compared between the two groups. Symptom Checklist-90 (SCL-90) was used to evaluate treatment effects of patients in two groups before and after the intervention.Results:There was no statistically significant difference in the surgical success rate, flap necrosis rate and incidence of vascular crisis between the observation group (100.00%, 2.94%, 2.94%) and the control group (96.77%, 12.90%, 16.13%) ( P>0.05) . The observation group had 1 case of deep venous thrombosis (DVT) and 2 cases of other complications, and the control group had 3 cases of pressure injury, 1 case of infection, 2 cases of DVT and 3 cases of other complications. The complication rate in the observation group was 8.82%, which was lower than 29.03% in the control group, and the difference was statistically significant ( P<0.05) . After intervention, the scores of anxiety and paranoia in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Psychological resilience intervention combined with prospective nursing has a good application effect on patients with free skin flap transplantation to repair skin and soft tissue defects of extremities. The complication rate is reduced, and mental health of patients is good.
