Objective:To investigate diagnostic and prognostic value of actin-binding protein ANLN in clear cell renal cell carcinoma(ccRCC)and its relationship with tumor microenvironment.Methods:Gene expression data and clinical data for ccRCC were downloaded from The Cancer Genome Atlas(TCGA).Relationship between ANLN expression and clinicopathological features was assessed by Wilcoxon rank sum test and Logistic regression.Receiver operating characteristic(ROC)curve was used to assess diagnostic value of ANLN expression in ccRCC.Kaplan-Meier and Cox regression analysis were used to investigate effect of ANLN expression on overall survival.Gene set enrichment analysis(GSEA)was used to identify signaling pathways associated with ANLN in ccRCC.Relationship between ANLN expression and immune infiltration was analyzed by ESTIMATE algorithm,tumor immune estima-tion resource(TIMER)and CIBERSORT algorithms.Relationship between ANLN and drug sensitivity was calculated using CellMiner database.Results:ANLN expression was significantly upregulated in ccRCC tissues.ANLN expression in ccRCC was correlated with clinicopathological features.ROC analysis showed that ANLN had a high diagnostic value in ccRCC.High ANLN expression was signifi-cantly associated with poor prognosis.Multivariate Cox regression analysis showed that high ANLN expression was an independent risk factor for overall survival in ccRCC patients.GSEA showed that ANLN was associated with multiple signaling pathways.In terms of immunity,ANLN was closely associated with tumor microenvironment,immune infiltration and immune checkpoint molecules in ccRCC.ANLN expression was negatively correlated with sensitivity of most antitumor drugs.Conclusion:ANLN is a potential diagnos-tic and prognostic biomarker and immunotherapeutic target for ccRCC.

Objective:To evaluate the optimization effect of transcutaneous electrical acupoint stimulation (TEAS) combined with moderate sedation with propofol (TEAS-propofol balanced anesthesia) for gastrointestinal endoscopy.Methods:This was a single-blind randomized controlled trial. American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 18-64 yr, undergoing elective gastrointestinal endoscopy at the Endoscopic Diagnosis and Treatment Center of the Affiliated Hospital of Qingdao University from May to August 2022, were divided into 2 groups using the block random allocation method: conventional anesthesia group (group C) and TEAS-propofol balanced anesthesia group (group TPB). Patients received moderate sedation with propofol plus routine anesthesia with fentanyl 50 μg in group C. In TPB group, TEAS was performed at bilateral Neiguan, Hegu and Zusanli acupoints before surgery until the end of surgery, and patients received propofol for moderate sedation (Modified Observer′s Assessment of Alertness/Sedation scale score was 3). The efficacy and safety of anesthesia and parameters related to outcomes were observed and recorded.Results:In this study, 66 patients were recruited, with 33 in each group, the failure rate of anesthesia in both groups was 3%, and no reflux or aspiration was found. Compared with group C, no significant changes were found in the patients′ satisfaction on the same day, intraoperative pain response score, incidence of intraoperative adverse reactions (tachycardia, hypertension, bucking and body movement), awake time, consumption of propofol, rate of intraoperative awareness and rate of patients hoping to receive the same anesthesia method again postoperatively ( P>0.05), the patients′ satisfaction was significantly increased on the next day ( P<0.05), the incidence of intraoperative respiratory depression, physician satisfaction, and degree of postoperative dizziness and nausea were significantly reduced ( P<0.05), and the discharge time and time to the complete recovery of normal behavior function was significantly shortened in group TPB ( P<0.05). Conclusions:The combination of TEAS at bilateral Neiguan, Hegu and Zusanli acupoints with moderate sedation using propofol for gastrointestinal endoscopy is not only safe and effective, but also beneficial to the postoperative outcome of patients, and the effect is better than that of conventional anesthesia with propofol and fentanyl.

Objective:To explore the application value of patient data-based real-time quality control (PBRTQC) in enhancing the effectiveness of internal quality control (IQC) management.Methods:From the PBRTQC real-time quality control intelligent monitoring platform integrated with the laboratory information system (LIS), a total of 35,631 test results of red blood cell (RBC) count, white blood cell (WBC) count, and dehydroepiandrosterone sulfate (DHEA-S) were collected from patients of the Department of General Xi'an Area Medical Laboratory Center from August 1, 2023, to April 1, 2024. The platform was used in patient data distribution characteristics test, EWMA real-time quality control chart procedure establishment, performance validation, effect evaluation, best procedure selection, and real-time operation. The performance evaluation indexes of the best PBRTQC procedure establishment, the cut-off limit range, weighting coefficient, cumulative mean, standard deviation (SD), coefficient of variation ( CV) of the EWMA real-time quality control chart, and the cumulative mean, SD, and CV of its internal quality control data in the same period were counted, and at the same time compared with the quality target (1/3TEa). Coefficient of variation analyses were performed to compare the quality control status of PBRTQC and conventional internal quality control in the presence of warning or alarm prompts based on quality control process records, and alarm messages. Results:The evaluation indexes of the optimal procedures for RBC count, WBC count, and DHEA-S were the probability of error detection (Ped) between 93%-97% and greater than 90%, the false positive rate (FPR) between 0.0%-0.5%, the false negative rate (FNR) between 3.0%-7.0%, and the average number of the patient sample until error detection (ANPed) between 5-11, which is in line with the optimal quality control efficacy quality requirements for the PBRTQC procedure. The patient outcome cut-off concentrations for the optimal procedure EWMA quality control charts ranged from RBC count (3.92-5.16)×10 12/L, WBC count (4.28-7.50)×10 9/L, and DHEA-S (830-2 160) μg/L; (2 160-4 210) μg/L. The weighting coefficients were 0.05, 0.03, and 0.03, respectively. The real-world application of the EWMA real-time quality control charts showed stable and excellent analytical performance of the measurement system, such as out-of-control alarm: RBC count, 1 true alarm, Ped of 95.85%, and FPR of 0%. The cumulative CV of EWMA was less than the quality target; the cumulative CV of DHEA-S was 7.66% and 9.47%, respectively, and the cumulative CV of low level was greater than the quality target (8.33%), and the cumulative CV of high and low levels were 4.12% and 6.25%. Conclusion:The PBRTQC EWMA method can monitor the patient data - in real-time and continuous way. It can also dynamically identify and provide early indication of small changes in analytical performance during the analysis process, and can be used as a supplement to quality control products to improve the efficacy of laboratory quality management.

A composite nystagmus classification framework enhanced by dual attention mechanism is proposed to address the problem that the existing researches only identify whether nystagmus occurs in a horizontal,vertical,or axial direction,but fail to consider the issue of composite nystagmus composed of multiple directions with various intensities in clinical practice.A spatiotemporal concentration algorithm for nystagmus videos is presented,and it combines convolutional neural networks and Hough transform to remove interference from invalid frames and regions and to improve the quality of nystagmus videos.Then,a dense optical flow algorithm is used to extract the optical flow field of eye movement.Finally,a composite nystagmus classification network based on dual attention mechanism enhancement is constructed.An improved efficient channel attention module is used to effectively obtain the direction and intensity of nystagmus in different channels of the optical flow map;and a temporal attention module is added at the end of the bidirectional long short-term memory network to achieve significant expression of classification results based on different temporal features.On the nystagmus dataset provided by the cooperating hospital,the proposed method has an accuracy rate of 83.17%for composite nystagmus classification,and achieved accuracy rates of 91.03%,89.74%,and 86.05%for individual horizontal,vertical,and axial nystagmus classifications.The proposed method realizes the intelligent classification of composite nystagmus and is valuable in clinic.

Objective:To understand and compare the clinical characteristics of children and adults infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant BA.5 and BA.2 subtypes in Shanghai City.Methods:The clinical data of 524 children hospitalized with coronavirus disease 2019(COVID-19) at the Children′s Hospital of Fudan University during the period of BA.5 predominance from December 1, 2022 to January 20, 2023 were collected, which included age, gender, clinical symptoms and laboratory examination results. And the clinical data of household close contacts were also collected. The clinical data of children and their household contacts infected with Omicron BA.2 subtypes during the period of BA.2 predominance from April 4 to April 30, 2022 were collected and compared.The clinical characteristic of critical and non-critical cases, child and adult cases during the period of BA.5 predominance were compared.Statistical analyses were conducted using independent samples t-test, Mann-Whitney U test, chi-square test or Fisher′s exact test. Results:The age of 524 hospitalized children was five days to 16 years old. Among them, 301(57.4%) were male and 223(42.6%) were female. Additionally, there were 29 critical cases (5.5%) and 495 non-critical cases (94.5%). Critical cases had significantly higher fever peak, more shortness of breath occurrence, more pneumonia and underlying diseases compared to non-critical cases, with statistically significant differences ( t=12.06, χ2=34.90, 10.04 and 31.10, respectively, all P<0.05). Regarding laboratory examinations, critical cases exhibited significantly higher frequencies of decreased lymphocyte count, elevated levels of C-reactive protein, procalcitonin and interleukin-6, abnormal liver function and kidney function, and abnormal creatine kinase isoenzyme compared to non-critical cases, with statistically significant differences ( χ2=8.18, Z=-4.61, Z=-4.28, Z=-5.13, χ2 =195.90, Fisher′s exact test and χ2=136.13, respectively, all P<0.05). Non-critical children cases infected with Omicron variant BA.5 subtype exhibited a higher proportion of symptomatic infections compared to adults. Among children, the occurrence rates of fever and gastrointestinal symptoms (nausea, vomiting, diarrhea) were higher, whereas among adults, the occurrence rate of cough was higher. The differences were statistically significant ( χ2=11.16, 11.83, 8.50 and 28.14, respectively, all P<0.05).From December 1, 2022 to January 20, 2023, a total of 588 children cases and 791 adult cases were collected, while from April 4 to April 30, 2022, a total of 355 children cases and 755 adult cases were collected.In the children group, the occurrence rates of cough, convulsions and critical cases were higher in BA.5 subtype-infected children compared to those infected with the BA.2 subtype, with statistically significant differences ( χ2=37.95, 40.78 and 15.54, respectively, all P<0.001).In the adult group, BA.5 subtype-infected individuals had higher fever peak, longer duration of fever, and higher occurrence of fever, cough and gastrointestinal symptoms, compared to those infected with the BA.2 subtype.The differences were statistically significant ( t=-4.40, Z=-9.64, χ2=47.29, 124.09 and 29.90, respectively, all P<0.001). Conclusions:During the peak periods of BA.5 subtype of the Omicron variant in Shanghai City, critical cases have severe systemic symptoms and a higher prevalence of underlying diseases compared to non-critical cases. Among non-critical cases infected with BA.5 subtype, the proportion of symptomatic infections in children is higher than adults, with fever and gastrointestinal symptoms more common than adults, while cough symptoms are more common seen in adults.The occurrence rate of convulsions and critical cases is higher in children infected with variant BA.5 subtype compared to those infected with BA.2 subtype.The systemic symptoms are more severe in adults infected with BA.5 subtype compared to those infected with BA.2 subtype.

Objective To compare the effect of serratus anterior plane block(SAPB)and thoracic para-vertebral block(TPVB)on acute and chronic pain and plasma tumor necrosis factor-α(TNF-α)level after breast cancer modified radical operation.Methods A total of 99 patients with elective breast cancer modified radical operation,aged 35-70 years,American Society of Anesthesiologists physical status(ASA):grade Ⅰ-11,Body Mass Index(BMI):18-25 kg/m2,were randomly divided into three groups:the simple patient-con-trolled intravenous analgesia(PCIA)group(C group),PCIA combined with TPVB group(TC group)and PCI A combined witj SAPB group(SC group).TPVB and SAPB were performed before induction in the TC group and the SC group,and the relevant situation of regional blocking operation was recorded.The Visual Analogue Scales(VAS)scores in rest and activity at 2,4,8,12,24,48 h after operation,effective pressing times of analgesic pump and remedial analgesia situation after operation were recorded.The TNF-α levels be-fore anesthesia and at postoperative 12,48 h,in postoperative 3,6 months were measured by enzyme linked immunosorbent assay(ELISA).Results Compared with the TC group,the block operation time in the SC group was shorter(P＜0.05).Compared with the C group,the VAS scores in the state of rest and activity at postoperative 2,4,8,12,24 h in the TC group and SC group were significantly decreased(P＜0.05),and the dosage of remifentanil during operation,incidence rates of postoperative nausea and vomiting,effective press-ing times of analgesic pump and rate of remedial analgesia were all decreased(P＜0.05).There was no statis-tical difference in the incidence rate of post-mastectomy pain syndrome(PMPS)among the three groups(P＞0.05).Compared with the C group,the levels of plasma TNF-α in the TC group and SC group were decreased at postoperative 12,48 h,in postoperative 3,6 months,moreover the VAS score in the patients with PMPS was lower(P＜0.05).Compared with the patients without PMPS occurrence,the levels of plasma TNF-α in postoperative 3,6 months in the patients with PMPS were significantly up-regulated(P＜0.05).Conclusion By blocking the afference of pain signals caused by peripheral injury and reducing plasma TNF-α level,SAPB or TPVB may relieve the acute and chronic pain degree in the patients with breast cancer modified radi-cal operation.

Objective:To explore the correlation between right atrial function parameters and prognosis in patients with chronic obstructive pulmonary disease(COPD) complicated with pulmonary hypertension.Methods:Eighty-four patients with COPD combined with pulmonary arterial hypertension treated with bosentan combined with milrinone admitted to the First Affiliated Hospital of Xinjiang Medical University during the period of February 2020 to June 2022 were selected as the study subjects, and they were divided into the effective group (63 cases) and the ineffective group (21 cases) according to the treatment effect. Right cardiac function parameters were measured by Philips iE33 color ultrasonography before treatment and 72 h after treatment. Logistic regression was used to analyze the risk factors affecting the treatment outcome of patients, and receiver operating characteristics (ROC) curve was used to analyze the predictive value of right atrial function parameters in the poor prognosis of patients with COPD complicated with pulmonary hypertension.Results:The main pulmonary artery diameter (MPA), right ventricular base transverse diameter (RVd1), right ventricular middle transverse diameter (RVd2), right atrial diameter (RAd) and right ventricular free wall thickness (RVWT) in the effective group were lower than those in the ineffective group: (2.65 ± 0.23) cm vs. (2.90 ± 0.44) cm, (3.46 ± 0.43) cm vs. (3.76 ± 0.72) cm, (3.48 ± 0.42) cm vs. (3.88 ± 0.69) cm, (3.53 ± 0.81) cm vs. (4.03 ± 1.20) cm, (0.63 ± 0.12) cm vs. (0.72 ± 0.21) cm; end-diastolic to end-systolic tricuspid ring displacement (TAPSE) was higher than that in the ineffective group: (2.08 ± 0.32) cm vs. (1.82 ± 0.46) cm, there were statistical differences( P<0.05). Logistic regression analysis showed that RVd1 increased ( OR = 3.717, P<0.05), RVd2 increased ( OR = 2.162, P<0.05), RAd increased ( OR = 2.838, P<0.05) and TAPSE reduction ( OR = 1.704, P<0.05) were risk factors for treatment failure in patients. The results of ROC curve showed that the area under the curve of RVd1, RVd2, RAd, TAPSE in predicting the therapeutic effect of COPD patients with pulmonary hypertension were 0.820, 0.831, 0.872, 0.909, respectively. Conclusions:The independent influencing factors of ineffective patients with COPD combined with pulmonary arterial hypertension treated with bosentan combined with milrinone are the increase of structural parameters of the right heart and the decrease of systolic function parameters. The therapeutic effect of patients can be evaluated clinically according to the level of each parameter.
