Investigation into the application of remimazolamin conjunction with low-dose propofolfor pediatricfiberoptic bronchoscopy.

This study delves into the effectiveness of combining remimazolam with low-dose propofol in pediatric fiberoptic bronchoscopy. Ninety children scheduled for fiberoptic bronchoscopy in our hospital were enrolled as research participants. Based on the intraoperative anesthetic drug regimen, the children were divided into three groups: group R (remimazolam 0.2-0.4 mg/kg), group P (propofol 1-3 mg/kg), and group RP (remimazolam0.2 mg/kg, propofol 0.5 mg/kg). Immediately post-anesthesia, group P exhibited lower blood pressure and heart rate (HR) compared to both group R and group RP (P < 0.05). As bronchoscope approached the glottis and epiglottis, group P continued to display lower blood pressure and HR compared to group R and group RP (P < 0.05). During lavage, group P maintained lower blood pressure and HR compared to both the R and RP groups (P < 0.05). Immediately post-anesthesia, group P demonstrated lower SpO2 compared to the R and RP groups (P < 0.05).During lavage, group P maintained lower SpO2 than group R and group RP (P < 0.05). In comparison with group R and group PR, group P showed shortened induction and recovery times (P < 0.05). The one-time entry success rate into the microscope was higher in group R than in group P, with the RP group showing an intermediate decreased (P < 0.05). Moreover, the cough score in R group was higher than in the P and RP groups (P < 0.05). Furthermore, the satisfaction rates of the RP group exceeded those of the R and P groups (P < 0.05). Remimazolam combined with low-dose propofol effectively balances the strengths and weaknesses of remimazolam and propofol, ensuring more stable hemodynamics, a lower incidence of adverse reactions, and optimal surgical conditions in pediatric fiberoptic bronchoscopy.

Circulating cell-free DNA as a biomarker for diagnosis of Schistosomiasis japonica.

BACKGROUND: Schistosomiasis, a neglected tropical disease, remains an important public health problem. Although there are various methods for diagnosing schistosomiasis, many limitations still exist. Early diagnosis and treatment of schistosomiasis can significantly improve survival and prognosis of patients. METHODOLOGY: Circulating cell-free (cf)DNA has been widely used in the diagnosis of various diseases. In our study, we evaluated the diagnostic value of circulating cfDNA for schistosomiasis caused by Schistosoma japonicum. We focused on the tandem sequences and mitochondrial genes of S. japonicum to identify highly sensitive and specific targets for diagnosis of Schistosomiasis japonica. RESULTS: Through data screening and analysis, we ultimately identified four specific tandem sequences (TD-1, TD-2, TD-3. and TD-4) and six mitochondrial genes (COX1(1), COX1(2), CYTB, ATP6, COX3, and ND5). We designed specific primers to detect the amount of circulating cfDNA in S. japonicum-infected mouse and chronic schistosomiasis patients. Our results showed that the number of tandem sequences was significantly higher than that of the mitochondrial genes. A S. japonicum infection model in mice suggested that infection of S. japonicum can be diagnosed by detecting circulating cfDNA as early as the first week. We measured the expression levels of circulating cfDNA (TD-1, TD-2, and TD-3) at different time points and found that TD-3 expression was significantly higher than that of TD-1 or TD-2. We also infected mice with different quantities of cercariae (20 s and 80 s). The level of cfDNA (TD-3) in the 80 s infection group was significantly higher than in the 20 s infection group. Additionally, cfDNA (TD-3) levels increased after egg deposition. Meanwhile, we tested 42 patients with chronic Schistosomiasis japonica and circulating cfDNA (TD-3) was detected in nine patients. CONCLUSIONS: We have screened highly sensitive targets for the diagnosis of Schistosomiasis japonica, and the detection of circulating cfDNA is a rapid and effective method for the diagnosis of Schistosomiasis japonica. The levels of cfDNA is correlated with cercariae infection severity. Early detection and diagnosis of schistosomiasis is crucial for patient treatment and improving prognosis.

An Evidence-Based Nursing Intervention Decreases Anxiety, Depression, Sleep Quality and Somatic Symptoms of Patients with Acute Ischemic Stroke.

Purpose: This study aimed to explore the effects of evidence-based nursing (EBN) intervention on anxiety, depression, sleep quality and somatic symptoms of patients with acute ischemic stroke (AIS). Methods: The eligible AIS patients were randomized into the intervention group and control group in a 1:1 ratio. Patients in both groups received routine nursing care. On the basis of routine nursing, patients in the intervention group also received EBN. Self-rating anxiety scale (SAS), self-rating depression scale (SDS), Pittsburgh Sleep Quality Index (PSQI), and the Patient Health Questionnaire-15 (PHQ-15) were used to assess patients' anxiety, depression, sleep quality, and somatic symptoms at baseline (T0) and 6 months after intervention (T1), respectively. Results: There was no difference in SAS, SDS, PSQI, and PHQ-15 scores at T0 between the 2 groups (all P > 0.05). Comparing to the control group, the intervention group had significantly lower SAS and SDS scores at T1 (P = 0.002, P < 0.001, respectively). The SAS and SDS score changes (T1-T0) were more evident in the intervention group than in the control group (all P < 0.001). No difference of PSQI or PHQ-15 score between the 2 groups was observed at T1. However, the PSQI and PHQ-15 score changes were more evident in the intervention group than in the control group (P = 0.044 and P = 0.007, respectively). Conclusion: EBN invention significantly improved anxiety, depression, sleep quality and somatic symptoms of patients with AIS.

Risks of postoperative respiratory failure in elderly patients after hip surgery: a retrospective study.

BACKGROUND: The purpose of this retrospective study was to investigate the determinants of postoperative respiratory failure in elderly patients with hip fracture. METHODS: The subjects of this study were 663 elderly patients who had hip fracture and had been treated with total hip arthroplasty at our hospital from January 2014 to May 2020. According to the occurrence of postoperative respiratory failure, 626 patients with no respiratory failure were retrospectively included in the control group, and 37 cases combined with respiratory failure were enrolled in the PRF group. The clinical and surgical data of the two groups were collected and analyzed to evaluate the determinants of respiratory failure by logistic regression analysis. RESULTS: There were no significant differences in the demographics and baseline variables including age, gender, fracture type and location between the groups (P > 0.05). All patients received hip surgery including total hip arthroplasty (THA), hemiarthroplasty (HA) and internal fixation with PFNA (proximal femoral nail anti-rotation). There were no significant differences in operative time and intraoperative blood loss between the groups (P > 0.05). However, close associations were found between pulmonary hypertension (univariate analysis: OR = 3.792, 95% CI = 1.421-10.203; multivariate analysis: OR = 1.132, 95% CI = 1.003-1.251), obstructive pulmonary disease (OR = 1.119, 95% CI = 1.009-1.238; multivariate analysis: OR = 13.298, 95% CI = 4.021-43.298), bronchiectasis and emphysema (OR = 4.949, 95% CI = 1.919-9.873; multivariate analysis: OR = 11.231, 95% CI = 187.87), and history of respiratory failure (OR = 6.098, 95% CI = 2.012-12.198; multivariate analysis: OR = 8.389, 95% CI = 2.391-21.982) with postoperative respiratory failure (P < 0.05). CONCLUSION: Pulmonary hypertension, abnormal lung texture, obstructive pulmonary disease, bronchiectasis, emphysema, history of respiratory failure, and hypoproteinemia may be risk factors for postoperative respiratory failure in elderly patients with hip fracture.

LncRNA miR143HG inhibits the proliferation of glioblastoma cells by sponging miR-504.

AIM: It is known that miR-504 can target p53 to promote cancer progression. Our bioinformatics analysis revealed that miR-504 could bind miR-143 host gene (miR143HG), suggesting that miR143HG might also have crosstalk with p53 in cancer progression. This study aimed to analyze the function of miR143HG in glioblastoma (GBM). METHODS: This study selected 64 GBM patients. GBM and non-tumor tissues were obtained from the patients. RT-qPCR was used to analyze gene expression. Survival curve analysis was performed to analyze the prognostic values of miR143HG for GBM. The crosstalk between miR143HG and miR-504 was analyzed by overexpressing them in GBM cells, followed by RT-qPCRs to detect their expression. CCK-8 assay was used to detect the cell proliferation ability. RESULTS: We found that miR143HG was downregulated in GBM and predicted poor survival. The mRNA expression levels of miR143HG and p53 were positively correlated in GBM tissues. Bioinformatics analysis suggested that miR143HG could form base paring with miR-504, which has been reported to target p53. Overexpression experiments revealed that miR143HG overexpression upregulated the expression of p53, while miR-504 overexpression inhibited the effect of miR143HG overexpression on the expression of p53. Moreover, overexpression of miR143HG and p53 decreased GBM cell proliferation, while overexpression of miR-504 increased GBM cell proliferation. In addition, overexpression of miR-504 attenuated the effect of miR143HG overexpression on GBM cell proliferation. CONCLUSION: Therefore, miR143HG may decrease the proliferation of GBM cells by sponging miR-504 to upregulate p53.

Transmembrane-4-L-six-family-1, a potential predictor for poor prognosis, overexpressed in human glioma.

Transmembrane-4-L-six-family-1 (TM4SF1), a tumor-associated antigen, is expressed in various human epithelial malignancies including breast, ovarian, lung, and colon carcinomas. The aim of the present study was to measure TM4SF1 gene expression in human glioma tissues and to investigate its relationship with patient outcome. We measured TM4SF1 expression in tumor tissue from 72 patients with glioma and in eight control brain tissues by means of quantitative reverse transcription-PCR, western blotting, and immunohistochemistry. The survival data including age, sex, Karnofsky performance scores, epilepsy, size of tumor, extent of resection, pathological grade, and TM4SF1 expression were analyzed using Kaplan-Meier analysis and the multivariate test method (Cox's proportional hazards model). We observed a higher level of TM4SF1 expression in human glioma tissues than in control brain tissues. Furthermore, TM4SF1 expression increased with ascending tumor grade (rs=0.950, P<0.05). Kaplan-Meier analysis with the log-rank test indicated that high TM4SF1 expression had a significant negative impact on overall survival (P<0.001). Moreover, multivariate Cox regression analysis revealed that TM4SF1 was an independent prognostic marker in glioma patients. These findings indicate that (a) TM4SF1 is overexpressed in human gliomas in general and (b) the precise level of expression might predict outcome and could be of clinical value.
