RESUMO
@#Objective To investigate the clinical effect of 3D computed tomography bronchial bronchography and angiography (3D-CTBA) and guidance of thoracoscopic anatomic pulmonary segmentectomy by Mimics software system. Methods A retrospective analysis was performed on patients who underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of Affiliated People's Hospital of Jiangsu University from June 2020 to December 2022. The patients who underwent preoperative 3D-CTBA using Materiaise's interactive medical image control system (Mimics) were selected as an observation group, and the patients who did not receive 3D-CTBA were selected as a control group. The relevant clinical indicators were compared between the two groups. Results A total of 59 patients were included, including 29 males and 30 females, aged 25-79 years. There were 37 patients in the observation group, and 22 patients in the control group. The operation time (163.0±48.7 min vs. 188.8±43.0 min, P=0.044), intraoperative blood loss [10.0 (10.0, 20.0) mL vs. 20.0 (20.0, 35.0) mL, P<0.001], and preoperative puncture localization rate (5.4% vs. 31.8%, P=0.019) in the observation group were better than those in the control group. There was no statistically significant difference in the thoracic tube placement time, thoracic fluid drainage volume, number of intraoperative closure nail bin, postoperative hospital stay, or postoperative air leakage incidence (P>0.05) between the two groups. Conclusion For patients who need to undergo anatomical pulmonary segmentectomy, using Mimics software to produce 3D-CTBA before surgery can help accurately identify pulmonary arteriovenous anatomy, reduce surgical time and intraoperative blood loss, help to determine the location of nodules and reduce invasive localization before surgery, and alleviate patients' pain, which is worthy of clinical promotion.
RESUMO
Objective:To analyze the hospitalization costs of delivery for postpartum women with different delivery methods, ages and comorbidities or complications, for references for medical institutions and medical insurance management departments to develop payment and compensation standards for inpatient delivery.Methods:The first page of medical records of hospitalized delivery women admitted to 8 large tertiary hospitals in Beijing from January 2018 to December 2021 were selected. Descriptive analysis was made on the mode of delivery, age, hospitalization expenses and cost structure of puerpera, as well as the hospitalization expenses of puerpera with different complications or complications. Wilcoxon rank sum test, Kruskal-Wallis H test, and Chi-squared test were used to statistically compare the level and structure differences between groups. Results:A total of 23 320 pregnant women were included, with an average age of 32.3 years. There were 13 605 cases of natural delivery and 9 715 cases of caesarean section. The median cesarean section rate in the right age group (<35 years old) and the elderly group (35-50 years old) were 36.73% and 56.58%, respectively, and the median hospital expenses were 5 865 yuan and 7 042 yuan, respectively. The median hospital expenses for natural delivery and caesarean section were 4 452 yuan and 10 033 yuan, respectively. The highest proportion of hospitalization expenses for natural delivery and cesarean section were treatment expenses (23.45%) and medicine expenses (29.19%), respectively. The median of hospitalization cost for women with≥2 comorbidities or complications (6 736 yuan) was higher than that for women with 1 comorbidities or complications (5 794 yuan).Conclusions:The hospitalization cost of cesarean section was significantly higher than that of natural delivery and the rate of cesarean section and the cost of delivery in women aged 35 and above were higher than those under 35 years old. The structure of hospitalization cost was different in different delivery modes, and the complications or complications had a greater impact on the average hospitalization expenses.
RESUMO
Objective To explore the relationship between case mix index ( CMI ) and the bed allocation in clinical departments, and to evaluate the performance of bed scale of departments at tertiary hospitals based on CMI. Methods Based on the HIS system of a tertiary hospital, the authors collected the disease treatment information and bed allocation information of each clinical department in 2015. The CMI value was calculated by means of diagnosis-related group( DRG) , while the proportion of cases and average daily beds occupancy corresponding to the quartile of the CMI value of each department was also counted. Then the bed occupancy and distribution of various patients were analyzed. Results The hospital′s overall CMI value, DRG groups, DRG cases at the departments, days of stay, DRGs, CMI values and its quartiles were calculated. It was found that the medical and surgical CMIs had a linear relationship with the critical proportion (r=0. 998, 0. 996, P<0. 001). The main influencing factors of average daily bed occupancy were ranged from high to low as followed: the number of cases that were allocated in the group, employee numbers and CMI (F=87. 656, P<0. 001). Conclusions CMI is an ideal indicator for the difficulty of medical services at different departments and for evaluating the bed scale performance. Hence it can be used as an important reference for bed number adjustment in hospitals.
RESUMO
Objective To investigate the effects of 17-β estradiol on hepatocyte apoptosis and the expression of Bcl-2 and Bax in hepatic tissue after reduced-size ischemia reperfusion injury and its mechanism in liver protection.Methods A rat model of reduced-size hepatic ischemia-reperfusion injury was established in 75 male Sprague-Dawley rats.They were randomly allocated into three groups:Sham group,ischemia-reperfusion(IR)group,and 17-β estradiol(E2 + IR)group.Liver functions,liver histology and hepatocellular apoptosis rates were observed after reperfusion.Hepatocellular ap optosis was determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL)method and the expression of Bcl-2 and Bax were determined by Western blotting.Results The levels of ALT and AST were higher and peaked after 12 h of reperfusion in the IR group compared with the sham group.The histological changes in the liver of the IR group consisted of hepatocyte swelling,hepatic sinusoids narrowing,inflammatory cell infiltration and hepatocyte necrosis in some areas of the livers.The IR group also exhibited an increased rate of hepatocellular apoptosis at 12 h after reperfusion.The protein expression of Bcl-2 decreased while the expression of Bax increased.In the 17-β estradiol group,the levels of ALT and AST were lower,the pathological changes were milder and the rate of hepatocellular apoptosis was lower at 12 h in comparison to those of the IR group.The expression of Bcl-2 was higher and the expression of Bax was lower in the 17-β estradiol group in comparison to those of the IR group.Conclusions 17-β estradiol can relieve the hepatic ischemia reperfusion injury in rat livers.17-β estradiol may inhibit apoptosis in hepatic tissue by up regulating Bcl-2 and down-regulating Bax,thus producing a protective effect on hepatic ischemia-reperfusion injury.
