Objective　To analyze the current situation and influencing factors of health-care seeking delay among pulmonary tuberculosis patients in Qingpu District of Shanghai from 2011 to 2022, and to provide a scientific basis for tuberculosis prevention and control. Methods　The data of pulmonary tuberculosis patients in Qingpu District of Shanghai from 2011 to 2022 was collected through the China Tuberculosis Information Management System to describe the distribution and change trend of the delay in health-care seeking. Univariate analysiswas performed using the chi-square (χ²) test, and the time trend of rates was tested with the trend chi-square (trend χ²) test. Multivariate logistic regression model analyzed the influencing factors of the delay in health-care seeking. Results　From 2011 to 2022, there were 3 488 cases of pulmonary tuberculosis in Qingpu District, with 1 438 patients experiencing health-care seeking delay. The median (quartile) number of days of delay was M (P25, P75) = 10 (2, 24) days, and the rate of health-care seeking delay was 41.23%. The annual rate of health-care seeking delay fluctuated between 33.88% and 50.45% from 2011 to 2022, with statistically significant differences between different years (χ²=38.355, P<0.001), and an upward trend in the health-care seeking delay rate was observed from 2020 to 2022 (χtrend²=13.290, P<0.001). Multivariate logistic regression analysis showed that compared to male, those under 25 years old, with local household registration, and detected through health check-ups, females (OR=1.21, 95%CI:1.04-1.41), those aged 45 to <65 (OR=1.36, 95%CI:1.06-1.75), intra-city migrants (OR=1.35, 95%CI:1.09-1.68), inter-provincial/overseas migrants (OR=1.50, 95%CI:1.23-1.83), and patients who directly sought medical care (OR=3.52, 95%CI:2.27-5.47), transfer treatment (OR=2.07,95%CI：1.31-3.25), referral (OR=2.16, 95%CI:1.36-3.44), follow-up (OR=3.07, 95%CI:1.74-5.44) patients with pulmonary tuberculosis were more likely to delay health-care, and the differences were statistically significant (P<0.05). Compared to sputum-positive patients, those with sputum-negative tests (OR=0.76, 95%CI: 0.59-0.97) were less likely to experience delayed health-care, and the difference was statistically significant (P<0.05). Conclusions　Health-care seeking delay of pulmonary tuberculosis patients is relatively common in Qingpu District of Shanghai. Corresponding intervention measures should be adopted for risk factors and key populations to further improve the health-care seeking delay.

Objective:To reveal the effect of β-sitosterol on cerebral ischemia-reperfusion injury (CIRI) in rats and whether its mechanism is related to endoplasmic reticulum stress (ERS).Methods:Fifty-three CIRI rats (CIRI models established by modified Longa method) were randomly divided into model group ( n=14), β-sitosterol low-dose group ( n=13), β-sitosterol medium-dose group ( n=13) and β-sitosterol high-dose group ( n=13); 12 rats underwent the same operation without blocking the middle cerebral artery were selected as sham-operated group. Rats in the sham-operated group and model group were given intragastric administration of 1 mL 5 g/L sodium carboxymethyl cellulose daily. Rats in the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group were given intragastric administration of 1 mL β-sitosterol at 10, 20 and 40 mg/kg/d (dissolved in 5 g/L sodium carboxymethyl cellulose), respectively, for 14 consecutive d. Neurological function was evaluated according to Zea Longa 5 method. Rats were sacrificed and brain tissues were collected. Volume of cerebral infarction was measured by 2,3,5-triphenyl tetrazolium chloride (TTC) staining. Brain injury and neuronal apoptosis were evaluated by HE staining, Nissl staining and TUNEL. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) contents were detected by water-soluble tetrazolium 1 (WST-1) method, colorimetric method or thiobarbituric acid (TBA) method, respectively. The mRNA and protein expression levels of protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme-1 (IRE-1), activated transcription factor-6 (ATF-6), glucose-regulated protein 78 (GRP78), C/EBP homologous protein (CHOP) and Caspase-12 in the brain tissues were detected by qRT-PCR or Western blotting. Results:Compared with the sham-operated group, the model group had significantly increased neurological function score, cerebral infarction volume and TUNEL positive rate, decreased SOD and GSH-Px content, increased MDA content, and increased mRNA and protein expressions of PERK, IRE-1, ATF-6, GRP78, CHOP and Caspase-12 ( P<0.05). Compared with the model group, the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group had significantly decreased neurological function score, cerebral infarction volume, and TUNEL positive rate, increased SOD and GSH-Px content, and decreased MDA content ( P<0.05); the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group had significantly decreased mRNA and protein PERK expressions (mRNA: 2.17±0.17, 1.79±0.07 and 1.33±0.07; protein: 5.11±0.52, 2.91±0.26 and 1.98±0.17), IRE-1 expressions (mRNA: 1.75±0.18, 1.65±0.08 and 1.32±0.08; protein: 5.00±0.31, 4.05±0.27 and 1.98±0.14), ATF-6 expressions (mRNA: 2.24±0.12, 1.77±0.14 and 1.37±0.13; protein: 4.93±0.45, 4.04±0.30 and 3.10±0.20), GRP78 expressions (mRNA: 2.67±0.16, 2.11±0.16 and 1.69±0.11; protein: 5.02±0.38, 2.97±0.26 and 2.05±0.22), CHOP expressions (mRNA: 2.01±0.16, 1.70±0.19 and 1.40±0.10; protein: 4.92±0.39, 4.02±0.27 and 3.08±0.22) and Caspase-12 expressions (mRNA: 1.85±0.09, 1.61±0.09 and 1.30±0.09; protein: 3.03±0.20, 2.19±0.11 and 1.82±0.11) compared with the model group (mRNA: 2.99±0.28, 2.27±0.12, 2.57±0.21, 3.46±0.20, 2.50±0.23 and 2.35±0.16; protein: 6.98±0.48, 6.03±0.58, 5.98±0.63, 7.10±0.45, 6.00±0.53 and 5.02±0.43, P<0.05). Conclusion:β-sitosterol attenuates CIRI in rats, whose mechanism may be related to inhibition of ERS signal pathway.

Objective:To investigate the early diagnostic value of human olfactomedin 4 (OLFM-4), signal peptide-CUB-epidermal growth factor-like domain-containing protein 1 (SCUBE-1), and liver-type fatty acid binding protein (L-FABP) in severe pneumonia complicated with acute kidney injury (AKI).Methods:A total of 162 patients with severe pneumonia admitted to the Haikou Third People′s Hospital from January 2020 to May 2023 were prospectively selected and divided into an AKI group (54 cases) and a non AKI group (108 cases) based on whether they developed AKI. Among AKI patients, there were 23 cases of AKI stage 1, 18 cases of AKI stage 2, and 13 cases of AKI stage 3. Enzyme linked immunosorbent assay was used to measure the changes in urinary OLFM-4, SCUBE-1, and L-FABP levels of patients at 12, 24, and 48 h after admission to the intensive care unit (ICU). The receiver operating characteristic (ROC) curve was applied to analyze the early diagnostic value of urinary OLFM4, SCUBE-1, and LFABP levels at different time points for AKI in patients with severe pneumonia.Results:There were statistically significant differences in ICU admission time, serum creatinine, urea nitrogen, uric acid, serum albumin, C-reactive protein, procalcitonin, Sequential Organ Failure Assessment (SOFA) score, and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score between the AKI group and the non AKI group (all P<0.05). At 12, 24, and 48 h after admission to the ICU, the urinary OLFM-4, SCUBE-1, and L-FABP levels in the AKI group were significantly higher than those in the non AKI group, and the differences were statistically significant (all P<0.001). The levels of urinary OLFM-4, SCUBE-1, and L-FABP in AKI stage 3 patients were significantly higher than those in AKI stage 1 and AKI stage 2 at all time points after admission to the ICU (all P<0.001), and the highest levels of urinary OLFM-4, SCUBE-1, and L-FABP were observed at the 24 h time point. The combination of 24 h urine OLFM-4 and SCUBE-1 with L-FABP had the highest area under the curve (AUC) for diagnosing severe pneumonia complicated with AKI (AUC=0.964, 95% CI: 0.908-0.997), with a sensitivity of 98.2% and specificity of 88.3%. Pearson correlation analysis showed that urinary OLFM-4 and SCUBE-1 levels in AKI patients were positively correlated with L-FABP ( r=0.870, 0.775, all P<0.001). Conclusions:Urine OLFM-4, SCUBE-1, and L-FABP are significantly elevated in the early stage of severe pneumonia complicated with AKI. The combined detection of these three parameters at 24 h has high value for the early diagnosis of AKI.

Objective:To investigate the clinical effectiveness of anastomosis fixation method of lifting the suborbicularis oculi fat (SOOF) and fixing with the orbital septum and fat to correct eyelid bags with tear trough deformity.Methods:A retrospective analysis was conducted on patients treated at Hunan Provincial People’s Hospital (the First Affiliated Hospital of Hunan Normal University) from January 2019 to January 2021. The patients underwent lower eyelid blepharoplasty via a sub-lower eyelid skin approach. During the surgery, the SOOF was lifted and fixed with the orbital septum and fat, correcting the eye bags, filling the tear troughs, and lifting the midface. Postoperative observations included incision healing and complications. The correction of eye bags, tear troughs, and midface sagging was followed up. Adobe Photoshop CS6 software was used to measure the vertical distance from the nasolabial and buccal fat prominent point to the lower eyelid margin before surgery and at the last follow-up to evaluate the correction of midface sagging. Data were expressed as Mean ± SD, and pre- and post-operative comparisons were analyzed using paired t-test, with P<0.05 indicating statistical significance. Patients’ and nurses’ satisfaction evaluations of surgical outcomes were classified into three levels: satisfied, basically satisfied, and dissatisfied, requiring consensus between the two evaluators. Results:A total of 132 patients (264 eyes) were included, consisting of 23 males and 109 females, with an average age of (50.3±6.0) years. Hirmand tear trough classification included 178 type Ⅱeyes and 86 type Ⅲ eyes. Postoperative wound healing was well, with no hematoma, infection, diplopia, corneal foreign body sensation, and discomfort from external eye corner tightness. Follow-up ranged from 6-12 months, with 252 out of 264 eye bags disappeared and 12 eye bags reduced. Among the 86 type Ⅲ tear trough eyes, 10 improved to type Ⅰ, while the remaining 76 type Ⅲ and 178 type Ⅱ tear troughs disappeared postoperatively. All 264 midface sagging cases showed improvement, with the vertical distance from the nasolabial fat prominence point to the lower eyelid margin significantly shortening postoperatively [(29.23±1.58) mm vs. (34.08±3.23) mm, t=22.88, P<0.001)]. Satisfaction evaluation result showed 118 cases were satisfied (satisfaction rate of 89.4%), and 14 cases were basically satisfied. Conclusion:The anastomosis fixation method of lifting the SOOF and fixing with the orbital septum and fat effectively removes eyelid bags, smooths tear troughs, and lifts the midface, achieving a rejuvenated appearance and renders a high patient satisfaction rate.

The training of lunar rover driving skills for astronauts requires the simulation of realistic motion perception characteristics.The key lies in understanding the differences of driving motion perception between ground and moon.A high-fidelity simulation scene was created to compare the driving characteristics of a lunar rover on the moon and on Earth.Additionally,a software framework based on spatial orientation model was developed to simulate and compare the differences in forward motion perception between lunar and ground driving.The results indicate that under lunar conditions the lunar rover experiences reduced acceleration changes and slower acceleration and deceleration,which increases the displacement of sideslip.Additionally,limited visual information leads to a significantly larger dynamic pitch angle perception compared to ground conditions,while static pitch angle perception is greatly reduced.However,this difference could be greatly reduced when visual information is available.The differences in motion perception characteristics were revealed between lunar and ground driving rover,providing a basis for optimizing lunar rover driving motion simulation strategies.

OBJECTIVES: Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model. METHODS: The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention. RESULTS: The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful. CONCLUSIONS Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.

Peritoneal dialysis (PD) catheter-related infections are important risk factors for catheter loss and peritonitis. 2023 International Society for Peritoneal Dialysis (ISPD) catheter-related infection recommendations have revised and clarified definitions and classifications of exit site infection and tunnel infection, such as cause-specific catheter-related infection, culture-negative catheter-related infection, refractory catheter-related infection, and infection- related catheter removal. A new target for the exit site infection rate should not exceed 0.40 episodes per year at risk. The recommendation about topical antibiotic cream or ointment to catheter exit site has been downgraded. New recommendations for exit site infection include clarified suggestion of exit site dressing cover and revised topical antibacterial agents as well as antibiotics treatment duration. In addition to catheter removal and reinsertion, new salvage options for catheter are suggested. The paper outlines the updated main content of the guide.

Objective: Schizophrenia (SCZ) is one of the most common and severe mental disorders. Modified electroconvulsive therapy (MECT) is the most effective therapy for all kinds of SCZ, and the underlying molecular mechanism remains unclear. This study is aim to detect the molecule mechanism by constructing the transcriptome dataset from SCZ patients treated with MECT and health controls (HCs). Methods: Transcriptome sequencing was performed on blood samples of 8 SCZ (BECT: before MECT; AECT: after MECT) and 8 HCs, weighted gene co-expression network analysis (WGCNA) was used to cluster the different expression genes, enrichment and protein-protein interaction (PPI) enrichment analysis were used to detect the related pathways. Results: Three gene modules (black, blue and turquoise) were significantly associated with MECT, enrichment analysis found that the long-term potentiation pathway was associated with MECT. PPI enrichment p-value of black, blue, turquoise module are 0.00127, <1×10-16 and 1.09×10-13, respectively. At the same time, EP300 is a key node in the PPI for genes in black module, which got from the transcriptome sequencing data. Conclusion It is suggested that the long-term potentiation pathways were associated with biological mechanism of MECT.
