Objective To determine whether regional arterial infusion (RAI) of 5-Fu and imipenem could decrease infection and mortality of acute necrotic pancreatitis (ANP) or not. Methods Fifty three patients with ANP were devided into three groups, group A, 16 patients who received intravenous 5-Fu and imipenem, group B, 22 patients who received 5-Fu by RAI and imipenem intravenously, and group C, 15 patients who received both 5-Fu and imipenem by RAI. Results The incidence of infection of ANP in group C (0%) was significantly lower than that in group A (50.0%) and B (27.2%), and the mortality rates in group B (18.1%) and C (13.3%) were significantly reduced as compared with group C (43.8%). Conclusion RAI of 5-Fu and imipenem was effective in reducing ANP infection and mortality rates.
ObjectiveTo establish the Z-score reference ranges of fetal arterial ductus (DA) inner diameter of normal fetus at 20 to 40 weeks’ gestation.MethodsA cross-sectional study was conducted in 781 normal singleton pregnancies with 20-40 weeks of gestation who underwent fetal echocardiography in the Third Affiliated Hospital of Henan University of Chinese Medicine from November 2018 to September 2019. The DA diameter, biparietal diameter (BPD), and femoral diaphysis length (FL) were measured and used to estimate gestational age (GA). With BPD, FL, and GA as independent variables and DA as dependent variables, linear regression analyses were conducted on the mean and standard deviation of each parameter to construct the best Z-score models.ResultsThe linear regression equations reflected strong positive correlations between the fetal biological growth parameter BPD, FL, GA, and fetal DA inner diameter. The heteroscedasticity of standard deviations was eliminated by the weighted regression of absolute stagger, and the best Z-score models were constructed. The linear regression equations of GA (week), BPD (mm), FL (mm), and DA inner diameter (mm) were as follows: Y=−2.661+0.217×GA, Y=−2.505+0.084×BPD, Y=−1.734+0.100×FL; the linear regression equations of GA (week), BPD (mm), FL (mm), and the standard deviation of DA inner diameter (mm) were as follows:Y=−0.273+0.025×GA, Y=−0.440+0.013×BPD, Y=−0.180+0.012×FL. According to the models, Z-score normal range reference values of fetal DA inner diameter were calculated.ConclusionsThere are good linear relationships between fetal DA inner diameter and GA, BPD and FL. The Z-score reference ranges of fetal DA diameter during mid- and late-pregnancy are constructed, which are helpful to quantitatively evaluate the normal development of fetal DA and provide a reference for clinical diagnosis of fetal DA abnormality.
ObjectiveTo evaluate the safety and feasibility of laparoscopic hepatectomy. Methods A total of 25 patients with hepatocellular carcinoma or liver hemangioma received laparoscopic hepatectomy, and perioperative results were analyzed. ResultsOnly one patient was converted to open hepatectomy because of massive hemorrhage. Blood loss of all patients during operation ranged from 100-1 200 ml with an average of 400 ml. The total blood volume of transfusion was 200-1 000 ml (mean 400 ml) in 14 patients. The operative time was 0.8-4.0 h (mean 2.3 h). All patients had no complications such as bile leakage and infection, and discharged from hospital in 5-10 d (mean 8 d) after operation. ConclusionLaparoscopic hepatectomy is safe and feasible to some liver diseases, but should be used with caution for the patients with tumor diameter over 9 cm and hepatic large vessels invaded by cancer.
ObjectiveTo investigate the value of chest high-resolution computed tomography (HRCT) score in evaluating the severity of hip fracture-induced early acute lung injury (ALI) in the elderly patients.MethodsThe clinical data of 289 elderly hip fracture patients in Chongqing Traditional Chinese Medicine Hospital from July 2014 to April 2020 were retrospectively analyzed. All patients were divided into two groups, including an ALI group (n=114, 36 males and 78 females at age of 82.94±6.85 years) and a non-ALI group (n=175, 51 males and 124 females at age of 84.42±6.31 years). General information, chest HRCT scores and PaO2/FiO2 were compared between the two groups. Correlation analysis was used to compare the relationship between chest HRCT scores and PaO2/FiO2. Multiple linear stepwise regression analysis was applied to evaluate the effective extent of the diffuse ground glass opacity (DGGO), intense parenchymal opacification (IPO), and reticulation HRCT scores to the overall HRCT scores.ResultsThe DGGO scores, IPO scores, reticulation scores, overall HRCT scores and PaO2/FiO2 were higher in the ALI group than those in the non-ALI group (P<0.001). In the ALI group, correlation analysis showed that DGGO, overall HRCT scores were in significantly negative correlation with PaO2/FiO2 (P<0.001). In addition, the correlation among PaO2/FiO2 and overall HRCT scores was more significant than that of DGGO scores. Multiple stepwise regression analysis indicated that DGGO, IPO, and reticulation scores were independent influencing factors for overall HRCT scores. Among the influencing factors, DGGO scores had the greatest impact, then IPO scores and reticulation scores. The HRCT signs of DGGO, IPO, and reticulation appeared simultaneously had the greatest effects on the overall HRCT scores.ConclusionThe chest HRCT score, which is associated with PaO2/FiO2, also can be used in the severity assessment of elderly patients with early ALI caused by hip fracture.
