Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

Objective To investigate the risk factors of hemodynamic instability after carotid artery stenting by meta-analysis.Methods Ten databases were searched:PubMed,ProQuest,ScienceDirect,Embase,Cochrane Library,Web of Science,China Knowledge Network,Wanfang Data,VIP Information Database,and China Biomedical Database.The search date was from inception until 2 February 2024,and meta-analysis was performed using Stata 16.0 statistical software.Results A total of 27 studies with 4199 subjects and 22 influencing factors were included.The studies showed a 37.4％(95％CI 30.3％-44.8％)incidence of haemodynamic instability after carotid stenting,Meta-analysis determined that age＞60 years(P＜0.001),hypertension(P＜0.001),calcified plaque(P＜0.001),stenosis＞70％(P=0.008),eccentric plaque(P=0.002),distance from the largest stenosis to the carotid bifurcation≤ 10 mm(P＜0.001),stenosis involvement of the balloon or bifurcation(P＜0.001),balloon post-dilation(P=0.003),open-loop stenting(P＜0.001),dilated balloon diameter≥5 mm(P=0.002),repeat balloon dilation(P=0.011)and balloon dilation pressure≥8 atm(P＜0.001)are risk factors for intraoperative and postoperative haemodynamic instability in patients undergoing carotid artery stenting surgery.Statin use was a protective factor(P＜0.001).Conclusions Medical staff working in the clinic should assess the patient's condition preoperatively,identify risk factors that may lead to haemodynamic instability,and avoid unnecessary intraoperative stimulation of patients who are already in a high-risk state.Reduce postoperative clinical complications in patients with carotid artery stenosis and improve patient recovery.

Objective To explore the effects of modified prone ventilation combined with bronchoscopic alveolar lavage on respiratory mechanics and hemodynamics in children with Acute Respiratory Distress Syndrome(ARDS),as well as to evaluate the clinical treatment efficacy.Methods A total of 96 ARDS children receiving mechanical ventilation treatment in the emergency intensive care unit of Kunming Children's Hospital from January 2021 to December 2023 were selected and randomly assigned into three groups:Group A(prone ventilation group,n=32),Group B(modified prone ventilation group,n=32),and Group C(modified prone ventilation combined with bronchoscopic alveolar lavage group,n=32).The changes in the following parameters before and after treatment among the three groups were compared:oxygenation indicators:arterial oxygen partial pressure(PaO2),arterial oxygenation index(PaO2/FiO2);respiratory mechanics indicators:lung compliance,mean airway pressure,plateau airway pressure,and total airway resistance;hemodynamic indicators:cardiac output,cardiac index,systemic vascular resistance index,and mean arterial pressure;clinical efficacy indicators time to disappearance of rales,mechanical ventilation duration,and length of hospital stay;and incidence of complications:arrhythmia,airway obstruction,pressure injuries,total incidence of catheter dislodgment,and gastric content reflux.Results The oxygenation indicators in Group C after treatment were superior to those in Groups A and B(P<0.05).The respiratory mechanics indicators in Group C after treatment were also better than those in Groups A and B(P<0.05).In terms of hemodynamics,there were no statistically significant differences in cardiac output,cardiac index,and mean arterial pressure among Groups A,B,and C after treatment(P>0.05).However,the SVRI in Group C was better than that in Groups A and B(P<0.05).Curative effect for Group C were also better than those for Groups A and B(P<0.05).The incidence of complications in Group C showed no significant difference compared to Groups A and B(P>0.05).Conclusion The modified prone ventilation combined with bronchoscopic alveolar lavage treatment scheme demonstrates better therapeutic effects compared to traditional treatment methods,significantly improving oxygenation and respiratory mechanics indicators as well as the systemic vascular resistance index in children,and is worthy of clinical promotion.

OBJECTIVE: To evaluate the efficacy and safety of a hospital-made resuscitation pack, a Chinese medicinal herbal compound formula designed to enhance recovery in post-bronchoscopy patients. METHODS: In this randomized, single-blind, placebo-controlled clinical trial, eligible patients were randomly assigned 1:1 to either the treatment or control groups. The patients in the treatment group applied the resuscitation pack, which contained aromatic compounded Chinese herbs. The patients in the control group applied a hospital-made, single herb placebo pack. Packs were placed on the Tiantu (CV 22) acupuncture point for 4 h as soon as the bronchoscopy finished. Efficacy indicators, such as recovery time, patients' symptoms including nausea and dizziness, and adverse events (AEs) were observed and compared. The outcome indices were evaluated at baseline, 1 and 24 h after the bronchoscopy. Subgroup analysis was further performed by patients' age and depth of sedation. RESULTS: When applying generalized estimating equations (GEE) to evaluate the intensity of post-bronchoscopy nausea and vomiting, the intensity was lower in the treatment group (163 cases) compared with the control group (162 cases; 95% CI: 0.004, 0.099, P=0.03]. Also, significantly lower intensity of nausea was observed in the 60-70 years of age subgroup (95% CI: 0.029, 0.169, P=0.006) and deep sedation subgroup (95% CI: 0.002, 0.124; P=0.04). There was no significant difference in dizziness between two groups by GEE (95% CI: -0.134, 0.297; P=0.459). In addition, no serious AEs were observed in either group. CONCLUSIONS Our study found that the resuscitation pack markedly improved patients' symptoms by reducing nausea and vomiting after bronchoscopy without AEs, compared with placebo in the perioperative period.

Neuropathic pain, a debilitating condition caused by dysfunction of the somatosensory nervous system, remains difficult to treat due to limited understanding of its molecular mechanisms. Bioinformatics analysis identified cerebellin 2 (CBLN2) as highly enriched in human and murine proprioceptive and nociceptive neurons. We found that CBLN2 expression is persistently upregulated in dorsal root ganglia (DRG) following spinal nerve ligation (SNL) in mice. In addition, transcription factor SOX11 binds to 12 cis-regulatory elements within the Cbln2 promoter to enhance its transcription. SNL also induced SOX11 upregulation, with SOX11 and CBLN2 co-localized in nociceptive neurons. The siRNA-mediated knockdown of Sox11 or Cbln2 attenuated SNL-induced mechanical allodynia and thermal hyperalgesia. High-throughput sequencing of DRG following intrathecal injection of CBLN2 revealed widespread gene expression changes, including upregulation of numerous NF-κB downstream targets. Consistently, CBLN2 activated NF-κB signaling, and inhibition with pyrrolidine dithiocarbamate reduced CBLN2-induced pain hypersensitivity, proinflammatory cytokines and chemokines production, and neuronal hyperexcitability. Together, these findings identified the SOX11/CBLN2/NF-κB axis as a critical mediator of neuropathic pain and a promising target for therapeutic intervention.

OBJECTIVES: To report the development, validation, and findings of the Multi-dimensional Attention Rating Scale (MARS), a self-report tool crafted to evaluate six-dimension attention levels. METHODS: The MARS was developed based on Classical Test Theory (CTT). Totally 202 highly educated healthy adult participants were recruited for reliability and validity tests. Reliability was measured using Cronbach's alpha and test-retest reliability. Structural validity was explored using principal component analysis. Criterion validity was analyzed by correlating MARS scores with the Toronto Hospital Alertness Test (THAT), the Attentional Control Scale (ACS), and the Attention Network Test (ANT). RESULTS: The MARS comprises 12 items spanning six distinct dimensions of attention: focused attention, sustained attention, shifting attention, selective attention, divided attention, and response inhibition.As assessed by six experts, the content validation index (CVI) was 0.95, the Cronbach's alpha for the MARS was 0.78, and the test-retest reliability was 0.81. Four factors were identified (cumulative variance contribution rate 68.79%). The total score of MARS was correlated positively with THAT (r = 0.60, P < 0.01) and ACS (r = 0.78, P < 0.01) and negatively with ANT's reaction time for alerting (r = -0.31, P = 0.049). CONCLUSIONS The MARS can reliably and validly assess six-dimension attention levels in real-world settings and is expected to be a new tool for assessing multi-dimensional attention impairments in different mental disorders.

Objective:This study aims to analyze the current status and risk factors of suicidal ideation in inpatients with schizophrenia and develop prediction models to improve the identification of individuals at high risk of suicide attempts.Methods:A total of 252 inpatients with schizophrenia were grouped with a 7∶3 ratio into modeling group ( n=176) and validation group ( n=76). The Beck Scale for Suicide Ideation (BSI), the Hamilton Anxiety Scale (HAMA), the Hamilton Depression Scale (HAMD), the Social Support-Rating Scale (SSRS), the Brief Psychiatric Rating Scale (BPRS), the Pittsburgh Sleep Quality Index (PSQI) were used to assess suicidal ideation, anxiety symptoms, depressive symptoms, social support, psychotic symptoms, and sleep quality, respectively. According to the presence of suicidal ideation, all patients were classified into those with and without suicidal ideation. The difference in each potential risk factor between the two groups was tested using the independent sample t-test and χ 2 test as appropriate. Multivariate Logistic stepwise regression analysis was used to identify independent risk factors of suicidal ideation. The R 4.1.2 software was used to construct the risk prediction model and draw a nomogram to visualize the Logistic regression model. The receiver operating characteristic (ROC) and the area under curve (AUC) were calculated to evaluate the predictability of this model. Internal validation of the model was examined using the Boostrap validation method. Results:Of the 252 inpatients with schizophrenia, 92 patients experienced suicidal ideation, with an incidence of 36.51%. The Logistic regression model revealed that gender (β=0.70, OR=3.66, 95% CI=1.02-3.85), education (β=-0.54, OR=0.85, 95% CI=0.19-0.89), chaperonage (β=1.32, OR=6.72, 95% CI=1.38-10.16), anxiety symptoms (β=0.08, OR=3.98, 95% CI=1.01-1.18), depressive symptoms (β=0.11, OR=28.30, 95% CI=1.07-1.16) were independent risk factors of suicidal ideation in inpatients with schizophrenia (all P?0.05). The AUC of the modeling group and validation group were 0.83 and 0.82, respectively. Conclusion:The incidence of suicidal ideation was high in inpatients with schizophrenia. The Logistic risk prediction model constructed in this study has good predictive efficacy, which can provide a theoretical basis for early identification of individuals at high risk of suicide attempts.

Pyroptosis is the programmed death of cells accompanied by an inflammatory response and is widely involved in the development of a variety of diseases, such as infectious diseases, cardiovascular diseases, and neurodegeneration. It has been shown that cellular scorching is involved in the pathogenesis of pulmonary arterial hypertension ( PAH) in cardiovascular diseases. Patients with PAH have perivascular inflammatory infiltrates in lungs, pulmonary vasculopathy exists in an extremely inflam-matory microenvironment, and pro-inflammatory factors in cellular scorching drive pulmonary vascular remodelling in PAH patients. This article reviews the role of cellular scorch in the pathogenesis of PAH and the related research on drugs for the treatment of PAH, with the aim of providing new ideas for clinical treatment of PAH.
