ObjectiveTo find out whether there is any difference in the monitoring results of mosq-ovitraps placed in different orientations in multi-storey residential areas, so as to provide a scientific basis for routine and emergency monitoring of Aedes albopictus with mosq-ovitraps in residential areas. MethodsFrom July 6th to October 26th 2023, one mosquito ovitrap was set up in each of the 4 orientations of east, south, west and north around the buildings in a multi-storey residential area in Jinhui Town, Fengxian District, Shanghai. Data was collected and recorded 72 hours after placement. The chi-square test was used to compare the mosquito ovitrap indices (MOIs) of two independent samples, and the Kruskal⁃Wallis H test was used to compare the MOIs of multiple independent samples. ResultsAfter 16 weeks of surveillance, 997 mosquito ovitraps were recovered, of which 211 were positive, with the mosquito ovitrap index (MOI) of 21.16% and the Aedes albopictus density index of 1.03 mosquitoes·ovitrap^-1. The MOIs were higher in September (24.22%) and October (23.96%), and the MOIs in the west, south and north within the two months were all above 20.00%. From July to October, the MOIs in the east, west, south and north were 20.70%, 22.20%, 25.50% and 16.20%, respectively, and the difference in MOIs among the 4 orientations was not statistically significant (χ²=6.647, P=0.084). Stratified analysis by month showed that in August, the south side of the multi-storey residential areas had the highest MOI (31.30%), the north side had the lowest MOI (1.30%), and there was a statistically significant difference in MOI in the east, west, south and north (χ²=25.986, P<0.001). In October, the MOI in the west was the highest (33.30%) and the MOI in the east was the lowest (6.30%), the difference in MOIs of the 4 orientations was statistically significant (χ²=12.007, P=0.007). The MOIs in the south side of the building in the outskirts of the residential area from the 1st week in July to the 4th week in October was lower (19.20%) than that in the south side of the inner building (31.70%), and the difference in MOI was statistically significant (χ²=5.118, P=0.024). ConclusionThe study of MOI in different orientations in a multi-storey residential area is a preliminary exploration based on field work, and the results show that there is a difference in MOIs in different orientations during the peak breeding period of mosquitoes. Further indicators such as temperature, humidity and wind speed in different orientations can be collected to explore the influencing factors of MOIs.

Objective To identify the causative variants in 5 Chinese families with tuberous sclerosis complex(TSC)to provide genetic counseling and prenatal diagnosis.Methods Genetic counseling and clinical diagnosis were performed in 8 patients from five unrelated TSC families by teleconsultation.With informed consent obtained from the participants,3 to 5 mL peripheral blood samples were collected from the probands and their family mem-bers for the extraction of genomic DNA.Candidate pathogenic variants were screened by panel sequencing(PS).The candidate pathogenic variants found in TSC1 and TSC2 by PS were validated by PCR-Sanger sequencing and bioinformatics analysis.Results All the pathogenic mutations were identified in the probands and their available family members.Causative variants in TSC1 or TSC2 were detected in all patients,including three reported variants and two novel variants.The two novel variants,TSC2:c.245G＞A and TSC2:c.235delG,which were predicted to cause the nonsense variant p.(Trp82?)and the frameshift variant p.(Val79Lysfs27?)respectively was believed to introduce premature stop codons.The analysis of family co-segregation and bioinformatics were identified as very positive factors for pathogenicity.Conclusions This result provides more evidences for the genetic counseling and prenatal diagnosis in these families and expand the spectrum of TSC2 pathogenic variants.

Objective:To explore the current situation of nurses′growth mindset ability and study its related influencing factors, so as to serve as a reference for improving nurses′ growth mindset ability.Methods:This was a cross-sectional survey, and 310 nurses from 5 tertiary hospitals in Shandong Province, Shanghai City, and Guangdong Province were selected as the survey subjects from April to June 2022 using convenience sampling method. The General Information Questionnaire, the Nurses′ Growth Mindset Assessment Scale, the Psychological Adaptability Self-Assessment Scale, the Chinese Big Five Personality Inventory Brief Version and the Team Psychological Safety Atmosphere Scale were used to investigate the growth mindset ability of nurses and its influencing factors.Results:Finally, 307 valid questionnaires were collected. There were 46 males and 261 females, aged 20-50 years old. The scores of the Nurses′ Growth Mindset Assessment Scale were (108.89 ± 29.32) points, the scores of the Psychological Adaptability Self-Assessment Questionnaire were 10.0(0.0, 20.0) points, the scores of the Chinese Big Five Personality Inventory Brief Scale were (162.37±43.82) points, and the scores of the Team Psychological Safety Atmosphere Scale were (55.84 ± 15.12) points. The highest education level ( B = 0.028, P = 0.040), professional title ( B = 0.033, P = 0.032), family economic support ( B = 0.025, P = 0.048), Chinese big five personality ( B = 0.039, P = 0.037), team psychological safety atmosphere ( B = 0.600, P<0.001) and psychological adaptability ( B = 0.313, P<0.001) had a significant effect on nurses′ growth mindset ability. Conclusions:The growth mindset ability of nurses is at the upper middle level, and the educational background, professional title, family economic support, personality characteristics, team psychological safety atmosphere and psychological adaptability of nurses are the significant influencing factors. Hospitals, social and health education systems can combine influencing factors to provide a harmonious working atmosphere for nurses, focusing on the improvement of nurses′ academic qualifications and the promotion of professional titles, cultivating nurses′ psychological adaptability, improving nurses′growth mindset ability, and improving the overall quality of the nursing service team.

BACKGROUND:The incidence of medial collateral ligament injuries in the knee joint is easy to lead to secondary meniscus and cartilage damage,and long-term chronic damage can lead to the occurrence of osteoarthritis.At present,there are few studies on the mechanics of meniscus and articular cartilage injury caused by medial collateral ligament rupture. OBJECTIVE:To investigate the effect of different degrees of medial collateral ligament injury on the biomechanics of meniscus and cartilage of knee joint. METHODS:The CT and MRI examinations of the knee joint of a healthy volunteer were performed to obtain the image data.The scanning data were imported into Mimics,Geomagic,and Solidworks software in turn.After registration and fusion,a 3D model of normal knee joint was established.On this basis,models of medial collateral ligament injury in different degrees of knee joint were simulated,which were divided into four groups,including:(1)medial collateral ligament was intact;(2)deep medial collateral ligament fracture;(3)superficial medial collateral ligament fracture;(4)complete rupture of medial collateral ligament.Finally,Ansys software was introduced to apply three modes of loads to the knee joint:(1)10 N·m valvaration torque was applied to the top of the femur.(2)A 4 N·m internal torque was applied to the top of the femur.(3)A 4 N·m external torque was applied to the top of the femur.The effects of four groups of models on knee biomechanics under different loads were analyzed. RESULTS AND CONCLUSION:(1)In the extension position of the knee joint,when a 10 N·m valgus torque was applied to the knee joint,the overall stress of the posterolateral meniscus increased with different degrees of medial collateral ligament injuries,while the stress of the articular cartilage did not change significantly.The peak stress of the posterolateral meniscus increased significantly with superficial medial collateral ligament rupture.(2)In the knee extension position,when a 4 N·m internal rotation torque was applied to the knee joint,the overall stress of the medial and lateral meniscus increased after different degrees of medial collateral ligament injury.When superficial medial collateral ligament rupture occurred,the peak stress of the meniscus shifted from the anterior horn of the medial meniscus to the anterior horn of the lateral meniscus.(3)In the knee extension position,applying a 4 N·m external rotation torque to the knee joint,the peak stress of the posterolateral meniscus increased more significantly than that of the medial meniscus,and the stress of the articular cartilage changed less.(4)These results show that the risk of meniscus injury secondary to superficial medial collateral ligament rupture is much higher than that of deep medial collateral ligament rupture when the knee is in extension,and the lateral meniscus is more vulnerable to injury than the medial meniscus.Both superficial medial collateral ligament and deep medial collateral ligament play an important role in the rotational stability of the knee joint.

Objective: To examine the association between high body fat mass and elevated blood pressure in children,so as to provide scientific evidence for the prevention and treatment of childhood hypertension. Methods: Participants were recruited from the second follow up survey of the Huantai Childhood Cardiovascular Health Cohort Study conducted in 2021 in Huantai County, Zibo City, Shandong Province, China. A total of 1 266 children aged 10-15 years old were included. The study categorized fat mass (FM), fat mass percentage (FMP), fat mass index (FMI), subcutaneous fat mass (SFM), and visceral fat mass (VFM), respectively, into normal and elevated groups based on age and gender specific median values ( P 50 ) in the study population. The multivariate Logistic regression model was used to analyze the association between the status of body mass and elevated blood pressure. A restrictive cubic spline (RCS) model was used to examine the dose response relationship between the levels of body mass and elevated blood pressure. Results: The detection rates of elevated blood pressure in children with elevated FM, elevated FMP, elevated FMI, elevated SFM, and elevated VFM were all significantly higher than those in the normal group ( P <0.05). After adjusting for all potential covariates, compared to the normal group, elevated FM ( OR =4.51, 95% CI =3.28-6.28), elevated FMP ( OR =4.51, 95% CI =3.28-6.27), elevated FMI ( OR =4.40, 95% CI =3.20-6.12), elevated SFM ( OR =4.52, 95% CI =3.29- 6.30 ), and elevated VFM ( OR =4.48, 95% CI =3.28-6.18) were all positively associated with elevated blood pressure ( P <0.05). The RCS analysis demonstrated that the high levels of FM, FMP, FMI, and SFM showed linear doseresponse relationships with elevated blood pressure ( P non linear >0.05), and elevated VFM was associated with elevated blood pressure in a nonlinear dose response relationship ( P non linear <0.05). Conclusions Children with elevated body fat have a higher risk of elevated blood pressure. There was a dose response relationship between high body mass content and elevated blood pressure in children. It is essential to take appropriate measures to reduce the elevated body fat in children, in order to prevent the occurrence of high elevated blood pressure in children.

Objective:To explore the association between changes in brain structural network during the early stage of stroke recovery and the onset of post-stroke depression (PSD).Methods:A total of 87 acute ischemic stroke patients scheduled for discharge, who were admitted to the Yixing Hospital Affiliated to Jiangsu University from March 2020 to May 2021, were prospectively collected. During the same period, 34 healthy control subjects matched with the stroke patients were also collected. All participants underwent systematic magnetic resonance imaging scans and scale assessments, and were followed up longitudinally for 2 years. Based on the occurrence of depression during follow-up, the stroke patients were divided into PSD group and post-stroke non-depression (PSND) group. Graph theoretical analysis was used to analyze the topological characteristics of brain structural network. Analysis of variance was used to explore the differences in brain structural network attributes among groups. Logistic regression model was used to analyze the predictive power of differential brain network attributes for PSD. Linear regression analysis was conducted to investigate the relationship between the synergism of non-rich-club regions and changes in rich-club connectivity.Results:The rich-club connectivity and synergism of the non-rich-club regions were significantly lower in the PSD group than in the PSND group (rich-club connectivity, P<0.01; synergism of feeder/local, P<0.001). The regression model demonstrated that the synergism of non-rich-club regions had a good predictive power for the occurrence of PSD ( OR=1.195, 95%CI 1.073-1.471, P<0.001). Furthermore, linear regression analysis revealed a significant correlation between the synergism of non-rich-club regions and Δrich-club connectivity ( r=-0.691, P<0.001). Conclusion:The good synergism of non-rich-club regions during the early stage of stroke recovery promotes the repair of rich-club connectivity and inhibits the onset of PSD.

Objective:To investigate the features of the brain structural network in patients with postpartum depression (PPD).Methods:This cross-sectional study included PPD patients who visited the mental health counseling clinic after delivery at the Jiangsu University Affiliated Yixing Hospital from June 2013 to September 2022 (PPD group). Matched non-PPD postpartum women based on age, years of education, and body mass index who came for postpartum follow-up (non-PPD postpartum group), and non-pregnant women who visited the hospital or underwent physical examinations during the same period (non-pregnant group) were also included. Demographic data and diffusion tensor imaging (DTI) data were collected for all three groups. The brain was partitioned into 90 regions using an anatomical template to construct the brain structural network. Network-based statistics (NBS) were applied to further screen and construct subnetworks. The efficacy of the subnetworks in identifying PPD was evaluated through multivariable logistics regression models and receiver operating characteristic curves. A comparison of the connectivity strength of white matter tracts and topological attributes of brain structural network parameters was conducted using independent samples t-tests, and the results were corrected using the false discovery rate (FDR) method. Results:(1) A total of 116 subjects were included, with 40 in the non-pregnant group, 40 in the non-PPD postpartum group, and 36 in the PPD group. PPD group had higher Edinburgh Postnatal Depression Scale (EPDS) scores than the non-pregnant and non-PPD postpartum groups [(18.0±4.1) scores vs. (2.5±1.2) and (6.1±2.1) scores, F=340.40; t=24.65,10.60 and 16.16 in pairwise comparison; all P<0.001]. (2) Compared to the non-pregnant group, there was a decrease in the connectivity strength of nine white matter tracts within the brain structural network of the postpartum group (including left dorsolateral superior frontal gyrus-left anterior cingulate and paracingulate gyrus, left dorsolateral superior frontal gyrus-right amygdala, left dorsolateral superior frontal gyrus-left insula, left insula-left lentiform nucleus, left insula-left hippocampus, left hippocampus-right amygdala, left hippocampus-left precuneus, left anterior cingulate and paracingulate gyrus-right amygdala, and right amygdala-right hippocampus) (all P<0.05, FDR corrected). No increased connection strengths were observed. There were no significant differences in the connection strengths of these nine tracts between the non-PPD and PPD groups. (3) A characteristic subnetwork for the maternal group was successfully constructed based on the nine tracts, which exhibited typical small-world properties (σ>1). Compared to the non-PPD maternal group, the characteristic path length in the PPD group was increased [(3.904±0.328) vs. (4.130±0.433), t=－2.58], and global efficiency was decreased [(0.361±0.036) vs. (0.331±0.053), t=2.91] (both P<0.05). Local property comparisons showed that the node efficiency values for the left dorsolateral superior frontal gyrus, left insula, left anterior cingulate and paracingulate gyrus, left hippocampus, right hippocampus, right amygdala, left precuneus and left putamen in the PPD group were significantly reduced [(0.273±0.023) vs. (0.267±0.030), t=0.98; (0.299±0.035) vs. (0.276±0.041), t=2.64; (0.265±0.019) vs. (0.258±0.025), t=1.38; (0.318±0.028) vs. (0.305±0.031), t=1.92; (0.312±0.027) vs. (0.302±0.031), t=1.50; (0.322±0.030) vs. (0.298±0.026), t=3.71; (0.356±0.040) vs. (0.338±0.056), t=1.62; (0.346±0.028) vs. (0.331±0.036), t=1.74; all P<0.05]. However, only the differences in node efficiency values for the left insula and right amygdala remained significant after FDR correction (corrected P=0.041 and 0.003). (4) Global efficiency, as well as node efficiency for the left insula and right amygdala, demonstrated good value for identifying PPD [areas under the curve (AUC) and their 95% CI were 0.827 (0.732-0.922), 0.741 (0.628-0.854), and 0.761 (0.653-0.867), respectively], with even better performance when combined [0.897 (0.828-0.969)]. (5) In the PPD group, global efficiency ( r=－0.43, P=0.008), node efficiency for the left insula ( r=－0.39, P=0.019), and node efficiency for the right amygdala ( r=－0.42, P=0.011) were all negatively correlated with EPDS scores. Conclusion:Aberrations in global efficiency, node efficiency for the left insula, and node efficiency for the right amygdala may serve as characteristic neuroimaging biomarkers for PPD.

Objective:To understand the clinical characteristics of human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) patients with renal injury after antiviral therapy in Henan Province, and to explore the risk factors of renal injury.Methods:A cross-sectional study was conducted to investigate HIV infection/AIDS patients receiving antiviral therapy in Zhengzhou Sixth People′s Hospital, Anyang Fifth People′s Hospital, Hebi Third People′s Hospital, Luo Yang Zhoushan Hospital and Lankao Central Hospital in Henan Province from April 1 to September 30, 2023. The clinical information including basic data, antiviral therapy regimens and comorbidities, and laboratory test results (blood urea nitrogen, serum creatinine, blood uric acid, urine routine, urine microalbumin, urine α 1-microglobulin (α 1-MG), urine β 2-microglobulin (β 2-MG), urine retinol binding protein (RBP), urine creatinine, HIV viral load, CD4 + T lymphocyte count) were collected. Multivariate binary logistic regression was used to analyze independent risk factors for renal injury. Results:A total of 2 526 HIV infection/AIDS patients were included, with the age of (45.52±14.28) years and 2 156 (85.4%) males. The main route of transmission was sexual transmission (91.6%, 2 314/2 526). The duration of antiviral therapy was 5.00(2.92, 8.00) years. Tenofovir (TDF)+ lamivudine (3TC)+ non-nucleoside reverse transcriptase inhibitors (NNRTI) accounted for 55.3%(1 396/2 526) of the current antiviral therapy regimen. The percentage of HIV viral load <50 copies/mL was 93.0%(2 350/2 526). The CD4 + T lymphocyte count was 476(337, 645)/μL. There were 156 patients (6.2%) complicated with hepatitis B and/or hepatitis C, 205 patients (8.1%) with diabetes, 379 patients (15.0%) with hyperlipidemia, and 189 patients (7.5%) with hyperuricemia. A total of 1 040 patients (41.2%) with renal injury were found through renal function test, including 355 cases (14.1%) with estimated glomerular filtration rate (eGFR) <60 mL/(min·1.73 m 2) or urine protein positive or urine albumin creatine ratio (UACR) ≥30 mg/g, 682 patients (27.0%) with pure tubular injury presented with only positive for urinary α 1-MG, urinary β 2-MG, or urinary RBP. eGFR< 60 mL/(min·1.73 m 2) was found in 71 cases (2.8%), eGFR from 60 to 89 mL/(min·1.73 m 2) was found in 509 cases (20.2%), and eGFR≥90 mL/(min·1.73 m 2) was found in 1 946 cases (77.0%). A total of 138 patients (5.5%) were identified as having combined chronic kidney disease (CKD). Among them, 110 patients (79.7%) were in CKD stages 1 to 2, and 117 patients (84.8%) were in urinary albumin A2 grade. Multivariate analysis of 355 patients with renal injury who had eGFR<60 mL/(min·1.73 m 2) or positive urine protein in urine routine or UACR ≥30 mg/g showed that ages of 50 to 69 years old (odds ratio( OR)=2.189, 95% confidence interval ( CI) 1.333 to 3.596, P=0.002)), ≥70 years old ( OR=5.190, 95% CI 2.912 to 9.248, P<0.001), female ( OR=1.685, 95% CI 1.241 to 2.286, P=0.001), combined opportunistic infection ( OR=2.521, 95% CI 1.567 to 4.056, P<0.001), combined hepatitis B ( OR=1.962, 95% CI 1.110 to 3.467, P=0.020), combined hepatitis C ( OR=1.883, 95% CI 1.043 to 3.400, P=0.036), combined diabetes ( OR=2.703, 95% CI 1.911 to 3.821, P<0.001), using TDF for two to four years ( OR=1.674, 95% CI 1.103 to 2.459, P=0.015), using TDF for greater than or equal to five years ( OR=1.880, 95% CI 1.287 to 2.746, P=0.001), using TDF combined with lopinavir/ritonavir (LPV/r) ( OR=3.610, 95% CI 2.273 to 5.734, P<0.001) and using TDF combined with non-LPV/r ( OR=1.495, 95% CI 1.036 to 2.157, P=0.031) were the risk factors of renal injury. Conclusions:There is a high proportion of renal injury among HIV infection/AIDS patients after antiviral therapy in Henan Province, including CKD and simple renal tubular injury. Older age, female, comorbidities, and long-term use of TDF are risk factors for renal injury.

Objective:To examine the structural network changes in participants with amnestic mild cognitive impairment(aMCI)and investigate the correlation between these changes and the onset of Alzheimer's disease(AD).Methods:In this prospective study, a total of 100 individuals with amnestic mild cognitive impairment(aMCI)were enrolled as the research group.Additionally, 25 healthy individuals who were matched in terms of age and sex were enrolled as healthy controls.Upon enrollment, all participants underwent MRI scans, neuropsychological assessments, and clinical evaluations.The participants were then followed every 6 months for a period of 36 months or until they withdrew from the study.Based on the outcome of the follow-up(whether Alzheimer's disease occurred), the aMCI participants were divided into two groups: stable aMCI group and progressive aMCI group.The Chinese version of the Brief Mental State Examination(MMSE), the Montreal Cognitive Assessment(MoCA), the Clinical Dementia Rating Scale(CDR), and the Auditory Word Learning Test(AVLT)were utilized to evaluate the overall mental and cognitive status of the subjects.Pearson correlation analysis was employed to investigate the relationship between structural network changes and cognitive decline.Logistic regression was performed to analyze the predictive ability of structural network changes in determining the onset of AD.Results:Compared to the stable aMCI group, the progressive aMCI group exhibited lower levels of global efficiency( P=0.002), local efficiency( P=0.007), feeder connections( P=0.003), local connections( P=0.008), and right precuneus nodal efficiency( P=0.010).Correlation analysis revealed that global efficiency( r=0.604, P=0.002), feeder connections( r=0.513, P=0.012), and right precuneus nodal efficiency( r=0.504, P=0.014)were correlated with AVLT-delay scores(baseline)in the progressive aMCI group.A logistic regression model demonstrated that global efficiency, feeder connections, and right precuneus nodal efficiency could significantly predict the onset of AD(all P<0.05, AUCunited=0.797, 95% CI: 0.684-0.884, sensitivity=73.91, 95% CI: 51.6-89.8, specificity=76.60, 95% CI: 62.0-87.7). Conclusions:Among participants with aMCI, individuals who exhibit lower global efficiency, feeder connections, or right precuneus nodal efficiency are at a higher risk of developing AD.These indicators are anticipated to serve as new targets for clinical intervention.

Objective:To investigate whether Lycopi Herba can serve as a viable alternative to Alismatis Rhizoma in the treatment of heart failure (HF) through network pharmacology and molecular docking techniques.Methods:TCMSP database was used to filter active components of Lycopi Herba and Alismatis Rhizoma. SwissTargetPrediction database was used to predict potential targets. HF-related targets were collected from databases such as GeneCards, OMIM, and DisGeNET. Venny 2.1.0 was used to draw a Venn diagram illustrating the intersection of targets between Lycopi Herba and Alismatis Rhizoma and HF. A protein-protein interaction (PPI) network was established using the String database, and key targets for the treatment of HF with Lycopi Herba and Alismatis Rhizoma were selected using Cytoscape 3.9.1 software to construct a component-intersection target network. The intersection targets were then analyzed for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways using Metascape. Molecular docking techniques were used to evaluate the affinity between active components and key targets.Results:Lycopi Herba primarily targeted pivotal proteins such as HMGCR and CYP27B1, while Alismatis Rhizoma had a broader target spectrum, including PPARA, JAK2, among others. Shared key targets between the two included HMGCR and ESR1, which were primarily involved in cholesterol synthesis and steroid hormone biosynthesis. Enrichment pathway analysis showed similarities in steroid metabolism between the two; Alismatis Rhizoma, however, was more likely to act through protein phosphorylation regulation and modulating the PI3K-Akt signaling pathway for HF treatment. A unique target for Lycopi Herba in treating HF was CHRM4, indicating its potential for blood pressure regulation and myocardial protection.Conclusions:Both Lycopi Herba and Alismatis Rhizoma exhibit certain commonalities in the treatment of HF, but Alismatis Rhizoma has a wider range of targets and signaling pathways, implying more extensive therapeutic potential. However, considering the nephrotoxicity of Alismatis Rhizoma, Lycopi Herba could be considered as an alternative treatment for HF, especially in patients with renal insufficiency or in the early stages of HF.
