Abstract: Objective To evaluate the application of TB laboratory detection technology in Liaoning Province from 2016 to 2022, and to provide scientific basis for further improving the detection rate of Mycobacterium tuberculosis in the province. Methods The medical records of registered tuberculosis patients in Liaoning Province from 2016 to 2022 were collected from the "Tuberculosis Information Management System" in the "China Disease Prevention and Control Information System" subsystem. Statistical analysis was performed for sputum coating, sputum culture, and molecular biology testing. Results From 2016 to 2022, a total of 152 778 patients with pulmonary tuberculosis were registered in Liaoning Province. The detection rate of sputum smear microscopy was 98.03% (149 775/152 778), the detection rate of sputum culture was 20.72% (31 661/152 778), and the detection rate of molecular biology testing was 20.21% (30 737/152 778). From 2018 to 2022, the rate of molecular biological detection showed an increasing trend (χ2trend=7 104.466, P<0.01), while from 2016 to 2021, the detection rate of sputum culture showed an increasing trend, with statistical significance (χ2trend=3,068.701, P<0.01). The sputum smear detection rate showed a downward trend(χ2trend=689.913, P<0.01). . There were significant differences in the results of sputum smear microscopy, sputum culture, and molecular biology testing, as confirmed by the McNemar test (P<0.01). The positive rate of pathogenic academics increased from 26.27% in 2016 to 51.55% in 2022, showing a yearly upward trend (χ2trend=5 262.863, P<0.01), with significant differences between each year (χ2=5 686.935, P<0.01). Among pulmonary tuberculosis patients with positive pathogenic microorganisms, the proportion of sputum smear-positive cases decreased from 94.32% to 52.36%, showing a downward trend (χ2trend=5 010.104, P<0.01). The proportion of culture-positive cases increased from 5.68% in 2016 to 12.83% in 2022, showing an upward trend (χ2trend=122.501, P<0.01). In Liaoning Province, molecular biology testing has been carried out since 2018, and the proportion of molecular biology-positive cases increased from 11.51% to 34.81%, showing an increasing trend (χ2trend=1 969.326, P<0.01). The number of positive patients in molecular biological tests in municipal hospitals accounted for 18.69% (8 386/44 778) of etiological positive patients, while the number of positive patients in county-level hospitals accounted for 13.61% (2 439/17 924) of etiological positive patients, with significant differences (χ2=231.594, P<0.01). Conclusions The implementation of molecular biology testing for tuberculosis in Liaoning Province is one of the main measures to improve the positive rate of etiology, and it helps to diagnose tuberculosis patients timely and accurately

Objective:To explore the value of magnetic resonance diffusion tensor imaging (DTI) in evaluating cerebrovascular small vessel disease (CSVD) in patients with systemic lupus erythematosus (SLE).Methods:Eighty-two patients with SLE combined with CSVD treated at Yixing People's Hospital from January to December 2022 were selected. They were divided into acute phase infarction group (16 cases), chronic phase infarction group (26 cases), and chronic ischemic lesion group (40 cases) based on routine MRI examination results. All patients underwent DTI examination to obtain the average diffusion coefficient (DCavg) and anisotropy score (FA) of the affected and contralateral normal white matter areas, and the evaluation value of DTI for CSVD in SLE patients was analyzed.Results:The DCavg value on the affected side of 82 patients was significantly higher than that on the healthy side: (11.10 ± 3.48) 10 -3 mm 2/s vs. (8.18 ± 2.42) 10 -3 mm 2/s, and the FA value on the affected side was significantly lower than that on the healthy side: 0.28 ± 0.05 vs. 0.45 ± 0.08, with a statistical significant differences ( P<0.05). The DCavg values of the acute infarction group, chronic infarction group, and chronic ischemic focus group were (11.88 ± 3.50), (9.69 ± 3.24) and (8.52 ± 2.34) 10 -3 mm 2/s, respectively, with statistical significant differences ( P<0.05). The FA values of the acute infarction group, chronic infarction group, and chronic ischemic focus group were 0.28 ± 0.04, 0.33 ± 0.06 and 0.40 ± 0.07, respectively, with statistical significant differences ( P<0.05). The receiver operating characteristic curve was drawn, and the results showed that the area under the curve (AUC) of the acute phase infarction group and the chronic phase infarction group evaluated by DCavg and FA alone and in combination were 0.757, 0.756, and 0.820, respectively. The AUC of the chronic phase infarction group and the chronic ischemic focus group evaluated by DCavg and FA were 0.772, 0.776, and 0.813, respectively. The AUC value of the combined evaluation was relatively large. Conclusions:DTI has good evaluation value for CSVD in SLE patients and can accurately determine the type of CSVD.

Exploring neural markers that predict trust behavior may help us to identify the cognitive process underlying trust decisions and to develop a new approach to promote interpersonal trust. It remains unknown how trust behavior may be predicted early in the decision process. We used electrophysiology to sample the brain activity while participants played the role of trustor in an iterative trust game. The results showed that during the trust generation stage, the trust condition led to higher frontocentral beta band activity related to cognitive inhibition compared to the distrust condition (item level). Moreover, individuals with higher frontocentral beta band activity were more likely to perform trust choices at the single-trial level (individual level). Furthermore, after receiving reciprocity feedback on trial

Objectives To evaluate the effectiveness of cognitive behavior therapy for insomnia (CBT-i) in chronic insomnia patients in terms of the improvements of psychological and sleep diary parameters. Methods Patients who met the diagnostic criteria of chronic insomnia, were divided into primary group or comorbid group. Both groups received standard CBT-i interventions. Psychological scales and sleep diaries were used to evaluate participants' severity of insomnia and psychological conditions related to insomnia at four time points:before intervention (baseline), immediate after intervention, 4 weeks and 16 weeks after intervention. Results Both groups achieved significant improvements after intervention on psychological measurements and sleep diary parameters. Such improvements were maintained at 4-week and 16-week follow-ups. The sleep diary data indicated that by the end of the intervention, there were significant differences on sleep onset latency(51.72 min to 10.53 min in primary group, P<0.01;59.26 min to 15.67min in comorbid group, P<0.01)and sleep efficiency (71%to 95%in primary group, P<0.01;68%to 90%in comorbid group, P<0.01). There were differences on sleep onset latency (10.00 min vs. 13.93 min,P<0.05), total sleep time (355.71 min vs. 327.85 min, P<0.05) and sleep efficiency (95%vs. 91%, P<0.01) in primary group and comorbid group respectively. No differences were found on wake after sleep onset in the two groups. Conclusions Chronic insomnia patients with or without comorbidities both have improvements after CBT-i. Sleep diary parameters rather than psychological measurements are different in two groups. Thus, CBT-i is an effective non-pharmaceutical therapy inpatients with chronic insomnia.

Objective:To evaluate the effect of esketamine combined with ultrasound-guided dorsal penile nerve block (DPNB) on negative postoperative behavioral changes (NPOBCs) in pediatric patients undergoing circumcision under general anesthesia.Methods:One-hundred and ninety-five pediatric patients, aged 4-8 yr, with body mass index of 10-35 kg, of American Society of Anesthesiologists Physical Status classificationⅠ or Ⅱ, undergoing elective circumcision under general anesthesia, were selected and divided into 3 groups ( n=65 each) using a random number table method: esketamine group (group E), DPNB group (group D) and esketamine combined with DPNB group (group ED). Propofol 1.5 mg/kg was intravenously injected, and the patients were admitted to the operating room after consciousness disappeared in the 3 groups. Esketamine 0.5 mg/kg was intravenously injected in E and ED groups, and the equal volume of normal saline was given in group D. D and ED groups underwent bilateral DPNB with 0.25 % ropivacaine 0.15 ml/kg under ultrasound guidance, with the maximum total amount of the drug not exceeding 10 ml. Fentanyl 1.0 μg/kg and propofol 2.0 mg/kg were intravenously injected prior to the skin incision in the three groups. If intraoperative body movement occurred, propofol 10 mg was added, which could be repeated. The occurrence of intraoperative body movement, respiratory depression and amount of propofol added was recorded. When postoperative pain (FLACC score >4) occurred, flurbiprofen 1 mg/kg was intravenously injected for analgesia, and the usage of flurbiprofen was recorded. When emergence agitation(PEAD score>10) occurred, propofol 1 mg/kg was intravenously injected for sedation, and the occurrence of emergence agitation was recorded. Parents were followed up by telephone at 1, 7 and 30 days postoperatively to assess the occurrence of NPOBCs using the PHBQ scale. Results:Fifty-six patients in group E and 59 patients in D and ED groups finally completed the study.Compared with group E, the incidence of intraoperative body movement was significantly decreased, the amount of additional propofol was reduced, the emergence agitation score, incidence of emergence agitation and severe agitation and usage rate of postoperative flurbiprofen were decreased, and the incidence of separation anxiety at 7 and 30 days postoperatively was decreased in D and ED groups, and the incidence of intraoperative respiratory depression was significantly decreased, and the incidence of NPOBCs at 7 and 30 days postoperatively was decreased in group ED ( P<0.05). Compared with group D, the incidence of intraoperative respiratory depression was significantly decreased, the amount of additional propofol was decreased, the usage rate of postoperative flurbiprofen and incidence of sleep anxiety at 1 day postoperatively were decreased ( P<0.05), and no significant change was found in the incidence of NPOBCs at each time point after operation in group ED ( P>0.05). Conclusions:Esketamine combined with ultrasound-guided DPNB can reduce the occurrence of NPOBCs in pediatric patients undergoing circumcision under general anesthesia.

Objective:To analyze the distribution and drug resistance of wound pathogenic microorganisms in outpatients of wound healing center so as to provide a basis for the standardized construction of wound healing centers.Methods:A retrospective case series study was used to analyzed the data of 365 outpatients treated at Ruijin Hospital, Shanghai Jiaotong University School of Medicine from December 2017 to October 2019. There were 220 males and 145 females, aged (58.8±18.9)years (range, 18-98 years). The patients included 92 first-visit patients and 273 re-visit patients. The culture results (positive rate of pathogenic microorganisms, bacterial species, bacterial distribution) and drug sensitivity results of the wound secretions were compared and analyzed.Results:(1) Among 365 samples of wound secretions, 198 patients were positive for pathogenic microorganisms with a positive rate of 54.3%. A total of 107 strains (51.0%) of Gram-positive bacteria were detected, mainly Staphylococcus aureus (70 strains, 33.3%); 95 strains (45.2%) of Gram-negative bacteria were detected, mainly Escherichia coli (20 strains, 9.5%), followed by Pseudomonas aeruginosa (17 strains, 8.1%); 8 strains (3.8%) of fungi were detected. (2) A total of 26 (28.3%) first-visit patients were positive for pathogenic microorganisms, and 172 (63.0%) re-visit patients were positive for pathogenic microorganisms. The rate of positive microorganism detection had significant differences between first-visit and re-visit patients ( P<0.05). (3) A total of 29 strains were detected in first-visit patients, including 16 strains (55.2%) of Gram-positive bacteria, 11 strains (37.9%) of Gram-negative bacteria and 2 strains (6.9%) of fungi. A total of 181 strains were detected in re-visit patients, including 91 strains (50.3%) of Gram-positive bacteria, 84 strains (46.4%) of Gram-negative bacteria and 6 strains (3.3%) of fungi. The microbial distribution was significantly different between first-visit and re-visit patients ( P<0.05). (4) Compared with first-visit patients, the resistance of Staphylococcus aureus isolated from the re-visit patients to spenicillin, oxacillin, ciprofloxacin, tetracycline, clindamycin, moxifloxacin, erythromycin, and levofloxacin were increased variably. No vancomycin-resistant Staphylococcus aureus was detected, indicating that the staphylococcus aureus presented in the wound was highly sensitive to vancomycin. Conclusions:Staphylococcus aureus is the most common microorganism in wound secretions in outpatients of wound healing center. The rate of positive pathogenic microorganisms in wound secretions of re-visit patients is significantly higher than that of first-visit patients, and the distribution of pathogenic microorganisms of first-visited and revisited patients differs significantly. The Staphylococcus aureus detected in re-visit patients has a higher resistance to common antibiotics compared with first-visit patients. It is suggested that timely detection of pathogenic microorganisms in outpatients and effective control and supervision of outpatient infections are important contents that cannot be ignored in the construction of wound healing center.

Background/Aims:
The shortage of donor liver hinders the development of liver transplantation. This study aimed to clarify the poor outcomes of functionally marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) after FML transplantation.
Methods:
Propensity score matching was used to control for confounding factors. The outcomes of the control group and FML group were compared to demonstrate the negative impact of FMLs on liver transplantation patients. We compared the clinical improvements of the different surgical types. To elucidate the underlying mechanism, we conducted bioinformatic analysis based on transcriptome and single-cell profiles.
Results:
FMLs had a significantly greater hazard ratio (HR: 1.969, P=0.018) than did other marginal livers. A worse 90-day survival (Mortality: 12.3% vs. 5.0%, P=0.007) was observed in patients who underwent FML transplantation. Patients who received FMLs had a significant improvement in overall survival after IFLT (Mortality: 10.4% vs 31.3%, P=0.006). Pyroptosis and inflammation were inhibited in patients who underwent IFLT. The infiltration of natural killer cells was lower in liver grafts from these patients. Bulk transcriptome profiles revealed a positive relationship between IL-32 and Caspase 1 (R=0.73, P=0.01) and between IL-32 and Gasdermin D (R=0.84, P=0.0012).
Conclusions
FML is a more important negative prognostic parameter than other marginal liver parameters. IFLT might ameliorate liver injury in FMLs by inhibiting the infiltration of NK cells, consequently leading to the abortion of IL-32, which drives pyroptosis in monocytes and macrophages.

To investigate the changes of aortic stiffness and its influencing factors in patients with chronic kidney diseases (CKD).Eightyfour patients with CKD from Department of Nephrology, Zhejiang Provincial People's Hospital were divided into the dialysis group (CKD stage 5,=48) and non-dialysis group (CKD stage 3-5,=36). Clinical data, biochemical parameters and echocardiography findings were collected. SphygmoCor pulse wave analysis system was used to obtain pulse wave analysis (PWA) parameters including central aortic systolic blood pressure (CSP), central pulse pressure (CPP), augmented pressure (AP), augmentation index (AIX), and heart rate 75-adjusted augmentation index (HR75AIX). The influencing factors of aortic stiffness were analyzed by spearman correlation analysis and multiple regression analysis.CSP, CPP, AP, AIX and HR75AIX in dialysis patients had no significant differences compared with those in non-dialysis group (all>0.05). Spearman correlation analysis showed that CSP was positively correlated with systolic blood pressure, diastolic blood pressure, cholesterol, low-density lipoprotein cholesterol, left atrial diameter (LA),left ventricular systolic diameter (LVDs), left ventricular diastolic diameter (LVDd), and negatively correlated with calcium and hemoglobin levels. CPP was positively correlated with systolic blood pressure, age, LA, LVDd, and negatively correlated with diastolic blood pressure and hemoglobin levels. AP was positively correlated with systolic blood pressure, age, LA, LVDd, and negatively correlated with hemoglobin levels. AIX was positively correlated with systolic blood pressure, age, sodium, and negatively correlated with phosphorus levels. HR75AIX was positively correlated with systolic blood pressure, sodium, cholesterol, and negatively correlated with hemoglobin and albumin levels. Multiple regression analysis showed that higher systolic blood pressure was the independent risk factor for CSP (β=0.944,<0.01); lower diastolic blood pressure (β=0.939,<0.01) and higher systolic blood pressure (β=-1.010,<0.01) were the independent risk factors for CPP; older age (β=0.237,<0.01) and higher systolic blood pressure (β=0.200,<0.01) were the independent risk factors for AP; higher systolic blood pressure (β=0.163 and 0.115,<0.05 and<0.01) and higher sodium (β=0.646 and 0.625, all<0.05) were independent risk factors for both AIX and HR75AIX.No significant correlation is observed between aortic stiffness and CKD of different stages. Control blood pressure and restrict sodium intake may be effective means of delaying arterial stiffness in patients with CKD.
