    • Comparison of CT characteristics between pulmonary cryptococcosis and lung cancer presenting as solitary nodules: a meta-analysis

      Objective To systematically review the CT characteristic differences between pulmonary cryptococcosis (PC) and lung cancer presenting as solitary nodules. Methods PubMed, Embase, Web of Science, Cochrane Library, Wanfang, China National Knowledge Infrastructure and SinoMed were searched to collect case-control studies of the patients with PC and lung cancer presenting as solitary nodules on CT. The search period was from databases establishment to December 2023. We conducted a meta-analysis on the included studies. Results A total of 7 studies were included, 342 PC patients, and 370 lung cancer patients. The meta-analysis results showed that compared with lung cancer, PC patients were more likely to have the following characteristics in CT (P<0.05): nodules located in the lower lobe of the lung [odds ratio (OR)=1.91, 95% confidence interval (CI) (1.39, 2.62)], presence of bronchial inflation sign [OR=5.79, 95%CI (1.45, 23.21)], and halo sign [OR=6.64, 95%CI (2.87, 15.38)]. Compared with PC, lung cancer patients were more likely to have the following characteristics in CT (P<0.05): nodules located in the upper lobe of the lung [OR=0.52, 95%CI (0.35, 0.78)], presence of lobulation sign [OR=0.15, 95%CI (0.08, 0.27)], spiculation sign [OR=0.48, 95%CI (0.35, 0.65)], pleural indentation sign [OR=0.15, 95%CI (0.04, 0.50)], and vascular bundle sign [OR=0.20, 95%CI (0.05, 0.77)]. There was no statistically significant difference in CT between PC patients and lung cancer patients in terms of lesion size, relationship with pleura, vacuolar sign, cavity, and whether the broad base was connected to pleura (P>0.05). Conclusions For CT showing solitary nodules, PC nodules are more likely to be distributed in the lower lobe of the lungs, with bronchial inflation sign and halo sign. Lung cancer nodules are more likely to be distributed in the upper lobe of the lungs, with lobulation sign, spiculation sign, pleural indentation sign and vascular bundle sign.

    • Effects of interleukin 10 gene modified bone marrow mesenchymal stem cells on expression of inflammatory cytokines and neuronal apoptosis in rats after cerebral ischemia reperfusion injury

      ObjectiveTo explore the effects of interleukin 10 (IL-10) gene modified bone marrow mesenchymal stem cells (BMSCs) on the expression of inflammatory cytokines and neuronal apoptosis in rats after cerebral ischemia reperfusion injury.MethodsBMSCs were cultured by whole bone marrow adherence screening method. The properties of BMSCs were identified by immunocytochemical methods. BMSCs at passage 3 were transfected with recombinant adenovirus IL-10 gene (AdIL-10-BMSCs). The model of middle cerebral artery occlusion was made in 40 adult male Sprague Dawley rats by thread embolism method. The rats were randomly divided into 4 groups (n=10). At 3 hours after modelling, the rats of groups A, B, C, and D received tail intravenous injection of 1 mL L-DMEM medium containing 10% FBS, 61.78 ng IL-10, 1 mL BMSCs suspension (2×106 cells/mL), and 1 mL AdIL-10-BMSCs cell suspension (2×106 cells/mL), respectively. The cells were labelled with BrdU before cell transplantation in groups C and D. At 7 days after reperfusion, the brain tissue was harvested to detect the expression of OX42 by immunohistochemical assay, to determine the concentration of tumor necrosis factor α (TNF-α) and IL-1β by ELISA, and to detect the apoptosis by TUNEL assay. BrdU labelled cells were observed by immunofluorescence staining in groups C and D.ResultsBrdU labelled positive cells with green fluorescence were observed in the brain tissue of groups C and D, which mainly distributed in the striatum, cerebral cortex, and subcortex around the infarction area. The number of OX42 positive cells was significantly less in groups B, C, and D than group A (P<0.05), and in group D than groups B and C (P<0.05). Compared with the other 3 groups, the contents of TNF-α and IL-1β significantly decreased in group D (P<0.05). TUNEL assay showed that the apoptotic cells (TUNEL positive cells) were mainly seen in the striatum and fronto parietal subcortical tissues (equivalent to ischemic penumbra). The number of TUNEL positive cells in group D was significantly less than that in groups A, B, and C (P<0.05).ConclusionAdIL-10-BMSCs can inhibit secretion of TNF-α and IL-1β from microglial cells and inhibit the nerve cell apoptosis around infarct brain tissue, which might contribute to its protective role upon cerebral ischemia reperfusion injury.

    • Causes for and countermeasures against day surgery cancellations

      Objective To analyze the causes for day surgery cancellations before admission or on the same day of operation, and put forward targeted measures to improve the medical resource utilization and patient satisfaction. Methods The basic information and clinical data of patients who had been scheduled for surgery in the Day Surgery Center of West China Hospital, Sichuan University between January 2018 and September 2021 were collected. The reasons for the surgery cancellations before admission or on the same day of operation were analyzed. Results From January 2018 to September 2021, a total of 45176 patients were successfully scheduled for day surgery, and 44300 patients completed surgery as planned. A total of 876 operations (1.94%) were cancelled after being scheduled, including 546 (1.21%) before admission and 330 (0.73%) on the surgery day. Ranked from high to low according to the cancellation rates, the top five departments were Department of Dermatology, Department of Vascular Surgery, Department of Hepatobiliary Surgery, Department of Otorhinolaryngology, Head and Neck Surgery, and Department of Gastroenterology, with a cancellation rate of 3.38% (8/237), 2.90% (25/863), 2.85% (101/3548), 2.48% (171/6893), and 1.91% (260/13578), respectively. In the reasons for cancellations, patient factors accounted for 57.31% (502/876) and medical management factors accounted for 42.69% (374/876). Conclusions The cancellations of day surgery mainly occur before admission, and are mainly caused by patient factors. It is necessary to strengthen the preoperative education for day surgery patients, and enhance the communication and cooperation between surgery physicians, nurses and technicians, in order to reduce the operation cancellation rate and make reasonable and efficient use of medical resources.

    • Automatic measurement of acetabular cup anteversion angle using an accurate recognition technology based on improved Otsu algorithm and feature point

      The orientation of the acetabular cup in hip joint anteroposterior radiograph is a key factor in evaluating the postoperative outcomes of total hip arthroplasty (THA). Currently, measurement of the acetabular cup anteversion angle primarily relies on manual drawing of auxiliary lines by orthopedic surgeons and calculations using scientific calculators. This study proposes an automated computer-aided measurement method for the acetabular cup anteversion angle based on hip joint anteroposterior radiograph. The proposed method segments hip prosthesis images using an improved Otsu algorithm, identifies feature points at the acetabular cup opening by combining circle-fitting theory and the cup’s geometric characteristics, and fits an ellipse to the cup opening to calculate the anteversion angle. A total of 104 hip joint anteroposterior radiographs, including 71 right-sided and 81 left-sided prostheses, were analyzed. Two orthopedic surgeons independently measured the postoperative anteversion angles, and the results were compared with computer-generated measurements for correlation analysis. Spearman and Pearson correlation analyses demonstrated significant correlations between the proposed method and manual measurements for both the right group (r = 0.795, P < 0.01) and the left group (r = 0.859, P < 0.01). This method provides a reliable reference for orthopedic surgeons to assess postoperative prognosis.

    • Clinical application and discussion of same-day discharge in day surgery

      Objective To investigate the safety and effect of same-day discharge in injection sclerotherapy for children with hemangioma (IJCH) and tension-free hernioplasty for adults with inguinal herinia (TFHA). Methods A retrospective analysis was conducted on patients undergoing IJCH or TFHA in the Day Surgery Center of West China Hospital of Sichuan University between November 2020 and October 2021. According to the patient’s condition and willingness, they were divided into same-day discharge group (162 children and 180 adults) and overnight hospitalization group (68 children and 271 adults). The amount of intraoperative bleeding, length of hospital stay, hospitalization expenses, pain before discharge, and short-term postoperative complications were compared between the two groups. Visual analogue scale was used for pain assessment in adults and children over 6 years old, and smiley face score was used in children below 6 years old. Results Compared with those in the overnight discharge group, the amount of intraoperative bleeding in the same-day discharge group was less [IJCH: (0.45±0.05) vs. (2.76±1.21) mL, P<0.05; TFHA: (1.20±0.05) vs. (6.76±2.30) mL, P<0.05], length of hospital stay was shorter [IJCH: (7.99±1.22) vs. (23.10±1.42) h, P<0.05; TFHA: (6.13±1.79) vs. (22.75±1.80) h, P<0.05], hospitalization cost was lower [IJCH: (5094.00±1320.14) vs. (6263.52±1220.20) yuan, P<0.05; TFHA: (7199.21±1535.84) vs. (7976.82±1967.82) yuan, P<0.05], pain before discharge was milder (IJCH: 0.05±0.02 vs. 0.50±0.01, P<0.05; TFHA: 1.20±0.01 vs. 2.01±0.20, P<0.05). There was no significant difference in the incidence of postoperative complications or unplanned revisit within 30 days between the two modes (P>0.05). Conclusions The same-day surgery mode is safe and feasible in IJCH and TFHA, and can shorten the length of hospital stay and reduce the cost of hospitalization. It is suggested to popularize this mode in clinical practice.
