  • Magnetic resonance imaging and differential diagnosis of perihepatic malignant peritoneal mesothelioma

    Malignant peritoneal mesothelioma is a very rare serous malignant tumor, which often manifests as multiple soft tissue masses in peritoneum and omentum, most of which are accompanied by ascites. In this study, a case of peritoneal malignant mesothelioma confirmed by pathological examination was presented. The case was rarely confined to the perihepatic peritoneum and grew into the liver. Without ascites, it was easy to be confused with intrahepatic lesions. Through case analysis, on the one hand, the MRI manifestations of malignant peritoneal mesothelioma are displayed. On the other hand, the main points of differentiation between extrahepatic and intrahepatic origin lesions are discussed, so as to improve the understanding and differential diagnosis ability of this disease.

  • Efficacy of orthopedic robot-assisted sacroiliac joint screws in the treatment of posterior pelvic ring fractures

    Objective To investigate the clinical effect of orthopedic robot-assisted sacroiliac joint screws in the treatment of posterior pelvic ring fractures. Methods Patients who underwent sacroiliac joint screw fixation in People’s Hospital of Deyang City between January 2018 and August 2021 were included, and the patients were divided intoa robotic group and a manual group by randomization. The robot group used robot-assisted insertion of sacroiliac joint screws, and the manual group used manual insertion of sacroiliac joint screws. The general condition, time of sacroiliac joint screw placement, intraoperative fluoroscopy times, guide needle drilling times, surgical blood loss, and Majeed pelvic function score were compared between the two groups. Results A total of 42 patients were included, and there was no significant difference in gender, age, body mass index , injury type or injury cause between the two groups (P>0.05). Finally, 21 screws were placed in 19 patients in the robotic group and 23 screws in 23 patients in the manual group. The wounds of the two groups were completely healed after operation, and there was no wound infection, iatrogenic vascular and nerve injury, and no loosening of internal fixation. There was no significant difference in screw placement time, blood loss or Majeed score between the two groups (P>0.05). The number of fluoroscopy (14.53±4.54 vs. 19.87±5.48) and drilling times (1.00±0.00 vs. 7.24±3.77) in the robotic group were less than those in the manual group, and the differences were statistically significant (P<0.05). Conclusion Orthopedic surgical robots have the advantages of minimally invasive, less fluoroscopy, and accurate screw placement in sacroiliac joint screw placement, and have good clinical results in the treatment of pelvic fractures.

  • Risk factors for new-onset atrial fibrillation after coronary artery bypass grafting under non-extracorporeal circulation alone: A retrospective cohort study

    Objective To explore the risk factors for new-onset atrial fibrillation (POAF) after off-pump coronary artery bypass grafting (OPCAB) alone. Methods A retrospective analysis was conducted on the clinical data of patients who underwent OPCAB in the Department of Cardiac Surgery Ward No.1 of Zhengzhou Seventh People’s Hospital from January 2020 to January 2024. Patients were categorized into POAF and non-POAF groups based on the occurrence of POAF. The clinical data of both groups were analyzed. Parameters underwent single-factor analysis, and variables with P≤0.05 in single-factor analysis were further analyzed through binary logistic regression to identify independent risk factors. Results A total of 496 patients were included. There were 312 males and 184 females, with age ranging from 50 to 78 years. There were 148 patients in the POAF group and 348 patients in the non-POAF group. The incidence of POAF after isolated OPCAB surgery was 29.8%. Results of univariate analysis showed that there was statistical difference in the incidence of diabetes (P=0.012), >75% stenosis of the left circumflex artery (LCX) (P=0.036), shock (P<0.001), graded left ventricular diastolic function (P<0.001), left ventricular ejection fraction (P<0.001), age (P<0.001), preoperative resting heart rate (P<0.001), left atrial diameter (P<0.001), E/A ratio (P<0.001), postoperative K+ concentration (P<0.001), and postoperative Mg2+ concentration (P<0.001). Binary logistic regression multifactor analysis revealed that age (OR=1.436, 95%CI 1.094 to 1.884, P=0.009), diabetes (OR=2.032, 95%CI 1.094 to 1.884, P=0.043), preoperative resting heart rate (OR=1.008, 95%CI 1.001 to 0.018, P=0.018), left atrial diameter (OR=4.409, 95%CI 1.711 to 11.359, P=0.002), E/A ratio (OR=1.713, 95%CI 1.115 to 2.633, P=0.014). The occurrence of POAF significantly prolonged mechanical ventilation time and ICU stay (both P<0.001). Conclusion Age, diabetes, left atrial diameter, EA ratio, and preoperative resting heart rate are potential independent risk factors for POAF following OPCAB surgery. Additionally, the occurrence of POAF post-surgery can lead to prolonged mechanical ventilation and extended stay in the intensive care unit.

    Objective To evaluate the efficacy of normalization management on prognosis in elderly patients with coronary artery disease, in aspects of drug compliance, readmission rate and quality of life. Methods A total of 110 patients above 65 years old with coronary artery disease visiting West China Hospital from August 2010 to February 2011 were investigated. The patients were divided into two groups: the intensive management group (n=55) and the general management group (n=55). The measures such as regular follow-up, regular examination and medical education were conducted in the intensive management group, and the two groups were observed in aspects of drug compliance, readmission rate and quality of life. Results After 1-year follow-up, the percentages of patients taking aspirin/clopidogrel (98.18% vs. 67.27%, Plt;0.05), nitrate (85.45% vs. 40.00%, Plt;0.05), ACEI/ARB (56.36% vs. 18.18%, Plt;0.05), β receptor blocker (58.18% vs. 29.09%, Plt;0.05) and statin (94.55% vs. 32.73%, Plt;0.05) were higher in the intensive management group than those in the general management group. Also, the readmission rate was lower (12.73% vs. 41.42%, Plt;0.05) and the score of quality of life was higher in the intensive management group than that in the general management group. Conclusion The normalization management guided by evidence-based medicine for the elderly patients with coronary artery disease is helpful to improve the drug compliance, reduce the readmission rate, and improve the quality of life.

  • Distribution Characteristics of Colorectal Cancer with Liver Metastases on CT Images

    Objective To investigate the relation between the sites of colorectal cancer and liver metastatic distribution. Methods The enhanced multiple-slice spiral CT images and clinical data of 105 cases diagnosed colorectalcancer with liver metastases admitted from January 2010 to April 2012 were analyzed retrospectively. Primary site of the tumor, numbers of the metastases on CT images, and the anatomical position of the inferior mesenteric vein (IMV) terminates were recorded. Results ①The ratio of metastases in the right and left hemiliver was 2∶1 for 38 right-sided primary tumors as compared with 1.2∶1 for 67 left-sided primary tumors. The pattern of lobar distribution was significantly different in the two groups (χ2=8.709, P=0.003). ②In the left-sided colon cancer group, the ratio of metastases in the right and left hemiliver was 65∶98 for 28 patients with IMV terminating in splenic vein (SpV), 116∶52 for 36 patients with IMV terminating in superior mesenteric vein (SMV), and 13∶15 for 3 patients with IMV terminating in the junction of SMV and SpV. The pattern of lobar distribution was significantly different among the three groups (χ2=28.575, P=0.000). Further comparison between the former two groups, the difference was statistically significant (χ2=27.951, P=0.000). ③In 25 patients with IMV terminating in SpV, the metastases of 19 cases were mainly distributed in the left lobe of liver (P=0.001);In 34 patients with IMV terminating in SMV, the metastases of 25 cases located mainly in the right hepatic lobe (P=0.000). Conclusions Right-sided colon cancers selectively involve the right lobe of liver, while left-sided tumors selectively involve the right lobe of liver when its IMV terminates in SMV and involve the left lobe when its IMV terminates in SpV, respectively. The discovery may help shorting the diagnostic workup in patients presenting with liver metastases from an unknown primary site, and may improve the detection rate of metastases in initial diagnosis and follow-up.

  • Clinical features of allergic and non-allergic asthma in adults

    Objective To investigate the clinical characteristics of allergic and non-allergic asthma in Chinese adult asthmatic patients. Methods Consecutive treatment-naive adult outpatients with asthma were retrospectively analyzed in West China Hospital, Sichuan University from October 2014 to June 2016. The patients were classified into a non-allergic asthma (NAAS) group and an allergic asthma (AAS) group by skin prick test or antigen-specific IgE test. The differences between allergic and non-allergic asthma were compared in respect of gender, age, asthma control test (ACT) score, lung function, fractional exhaled nitric oxide (FeNO) level, body mass index (BMI), disease severity,etc. Results A total of 131 patients were enrolled in which 72 cases (54.96%) were allergic asthmatics and 59 cases (45.04%) were non-allergic asthmatics. The level of FeNO was statistically different (t=–2.762,P=0.007) between the NAAS group and the AAS group [(51.1±32.6)ppbvs. (69.1±41.7)ppb]. Seventeen cases of the NAAS group and 48 cases of the AAS group were complicated with rhinitis with statistically significant difference (χ2 =19.396,P=0.000). Airway limitation reversibility test showed that there were 37 cases in AAS and 20 cases in NAAS with no airway obstruction (NAO), 26 cases in AAS and 22 cases in NAAS with reversible airflow obstruction (RAO), 9 cases in AAS and 17 cases in NAAS with irreversible airflow obstruction (IAO), respectively, with statistically significant difference between two groups (Z=–2.461,P=0.014). There were 20 cases (33.9%) in NAAS and 37 cases (51.4%) in AAS with mild intermittent or persistent asthma, 18 cases (30.5%) in NAAS and 19 cases (26.4%) in AAS with moderate persistent asthma, 21 cases (35.6%) in NAAS and 16 (22.2%) in AAS with severe persistent asthma, respectively, with statistically significant difference (Z=–2.115,P=–0.034). The age, ACT score, FEV1%pred, and BMI had no statistical difference between two groups (allP>0.05). Conclusion Compared with allergic asthma, non-allergic asthma has less rhinitis, lower FeNO levels and higher prevalence of irreversible airflow obstruction.

    Objective To explore the clinical effect of multidisciplinary team (MDT) in elderly patients with hip fracture under the model of close-type medical alliance. Methods The elderly patients with hip fracture treated in the Department of Orthopedics of Deyang People’s Hospital between January 2015 and December 2020 were included retrospectively. According to different treatment modes, the patients were divided into traditional mode treatment group (traditional group) and MDT mode treatment group (MDT group). The waiting time for operation, hospitalization time after operation, total hospitalization time, total hospitalization cost, and death and loss of follow-up were analyzed. Results A total of 661 patients were enrolled, including 275 in the traditional group and 386 in the MDT group. There was no significant difference between the two groups in terms of gender, age, Charlson comorbidity index, types of fracture or surgical methods (P>0.05). The waiting time for operation [5.50 (3.50, 7.50) vs. 6.00 (4.00, 6.00) d; Z=−3.473, P=0.001], hospitalization time after operation [7.44 (6.27, 8.67) vs. 8.34 (6.72, 13.70) d; Z=−4.996, P<0.001] and total hospitalization time [12.95 (10.46, 16.30) vs. 15.49 (11.77, 19.91) d; Z=−5.718, P<0.001] in the MDT group were shorter than those in the traditional group. The total hospitalization cost of the MDT group was higher than that of the traditional group, but the difference was not statistically significant [39 300 (33 400, 46 400) vs. 38 000 (31 800, 44 000) Yuan; Z=1.524, P=0.128]. There was no significant difference in the lost follow-up rate between the traditional group and the MDT group (9.82% vs. 6.48%; χ2=2.474, P=0.116). Except in-hospital mortality and 30-day postoperative mortality (P>0.05), there was significant difference between the traditional group and the MDT group in 6-month (6.45% vs. 2.77%; χ2=4.875, P=0.027) and 1-year (11.29% vs. 6.37%; χ2=4.636, P=0.031) postoperative mortality. Conclusion Under the model of close-type medical alliance, MDT can reduce the waiting time for operation, hospitalization time after operation, total hospitalization time, as well as 6-month and 1-year postoperative mortality.
