Aim To observe the intervention effects of sodium aescinate on acute lung injury model of rats induced by oleate. Methods Fifty four male SD rats were randomly divided into five groups: normal control group, sodium aescinate control group (without oleate) , oleate model control group,medrol interventional group and sodium aescinate interventional group. Acute lung injury models of rats were made by injecting oleate (OA, 0. 1 ml · kg~(-1) ) through caudal veins, and then rats were observed and killed to detect correlated in-dice. The observation indice were the histomorphology of lung, the wet and dry weights of lung ( W/D), score of injury of lung under light microscope (IQA ) , partial pressure of oxygen in artery ( PaO_2) , the levels of SOD and MDA in blood plasma and lung tissue. Results ① Histomorphology of lung: Lung surface hyperemia relieved obviously and pink secretion from trachea of rats in sodium aescinate interventional group and medrol interventioal group decreased significantly compared with oleate model control group. Under light microscope , compared with oleate model control group, effusion of inflammatory cells in alveolar space of rats in sodium aescinate interventional group and medrol interventional group decreased. ② The wet and dry weights of lung ( W/D ) ; W/D of rats in oleate control model group increased obviously compared with those in normal control group, W/D of rats in sodium aescinate interventional group and medrol interventional group decreased obviously compared with those in oleate model control group. ③ Score of injury of lungs under light microscope (IQA) ; IQA of rats in oleate model control group advanced obviously compared with that in normal control group. IQA of rats in sodium aescinate interventional group and medrol interventional group lowered significantly compared with that in oleate model control group.④ Partial pressure of oxygen in artery (PaO_2) : PaO_2 of rats in oleate model control group lowered significantly compared with that in normal control group. PaO_2 of rats in sodium aescinate interventional group and medrol interventional group improved significantly compared with that in oleate model control group. ⑤ The levels of SOD and MDA in blood plasma and lung tissue:The levels of SOD in plasma and lung tissue of rats in oleate model control group lowered significantly compared with those in normal control group. SOD in plasma and lung tissue of rats in sodium aescinate in-terventional group and medrol interventional group increased significantly compared with that in oleate model control group. The levels of MDA in plasma and lung tissue of rats in oleate model control group lowered significantly compared with those in normal control group. MDA in plasma and lung tissue of rats in sodium aescinate interventional group and medrol interventional group increased significantly compared with that in oleate model control group. Conclusion Sodium aescinate can improve W/D, IQA and PaO_2 by adjusting oxidization of the acute lung injury model of rats, which may provide a possible path for treating acute lung injury in clinical practice.

Objective:To evaluate the application value of electrical impedance tomography(EIT)imaging combining bedside bronchoscopy sputum suction by observing the changes of pulmonary ventilation, tidal volume and dynamic pulmonary compliance after bedside bronchoscopy sputum suction in elderly stroke-associated pneumonia(SAP).Methods:A randomized controlled study was conducted.Patients with SAP admitted to the respiratory intensive care unit of Henan Provincial People's Hospital from January 2017 to December 2018 were enrolled as research objects.They were divided into the control group versus observation group with the only difference in receiving bedside bronchoscope sputum suction replacing control's receiving conventional sputum suction.Impedance imaging region of interest 4(ROI4)values collected by using EIT at admission and 1, 3, 5 days after fiberoptic bronchoscope sputum suction were compared between the two groups.Meanwhile, the tidal volume, dynamic lung compliance, the duration of mechanical ventilation and hospitalization time in intensive care unit were recorded in the two groups.Results:A total of 78 patients meeting an inclusion and exclusion criterion were enrolled, with 37 cases in the control group and 41 cases in the observation group.Compared with control group, the bronchoscope sputum suction group showed the significantly increased regional gas distribution values(2.24±0.77% vs.0.49±0.65%, 7.05±0.77% vs.2.49±0.87%, 12.34±1.47% vs.5.57±0.50%, t=10.85, 24.56 and 26.54, respectively, all P<0.001)at 1, 3, 5 days after fiberoptic bronchoscope sputum suction.The tidal volume and dynamic lung compliance were significantly higher in the observation group than in the control group at 1, 3, 5 days after fiberoptic bronchoscope sputum suction.The duration of mechanical ventilation and hospitalization time in the intensive care unit were shorter in the observation group than in the control group(12.22±0.88 d vs.14.65±0.92 d, 18.41±1.12 d vs.21.14±1.06 d, t=11.91 and 11.01, both P< 0.001). Conclusions:For patients with SAP, an intermittent bedside fiberoptic bronchoscope sputum suction can effectively improve the pulmonary ventilation in the dorsal area, optimize pulmonary respiratory dynamics, facilitate the early withdrawal of the mechanic ventilation, and shorten the hospitalization time in the intensive care unit.

ObjectiveTo investigate the diagnostic efficiency of FibroTouch, FibroScan, and acoustic radiation force impulse (ARFI) for liver fibrosis in patients with primary biliary cholangitis (PBC). MethodsA retrospective analysis was performed for the patients who underwent liver biopsy and were then diagnosed with PBC in Beijing Friendship Hospital, Capital Medical University, from September 2014 to October 2018, and the METAVIR scoring system was used to evaluate the degree of liver fibrosis and inflammation. Within 1 week after liver biopsy, FibroTouch, FibroScan, and ARFI were used to measure liver stiffness (LS); with pathological results as the gold standard, the area under the ROC curve (AUC) was used to compare the value of FibroTouch, FibroScan, and ARFI in the diagnosis of liver fibrosis in PBC patients, and related influencing factors were analyzed; Youden index was used to calculate the cut-off values of LS for different degrees of liver fibrosis. The Kruskal-Wallis H test was used for comparison between multiple groups, and P value corrected by the Bonferroni method was used for further comparison between two groups. A Spearman correlation analysis was performed, and a multiple linear regression model was used for multivariate analysis. ResultsA total of 68 patients with PBC were enrolled in the study, among whom 13 had F0 liver fibrosis, 15 had F1 liver fibrosis, 18 had F2 liver fibrosis, 12 had F3 liver fibrosis, and 10 had F4 liver fibrosis. LS obtained by FibroTouch (FT-LS), LS obtained by FibroScan (FS-LS), and LS obtained by ARFI (ARFI-LS) were strongly positively correlated with the degree of liver fibrosis (r=0.798, 0.782, and 0.742, all P＜0.001). FT-LS had AUCs of 0.922, 0.881, and 0.926, respectively, in the diagnosis of F≥2, F≥3, and F=4 liver fibrosis, and the corresponding cut-off values were 10.5 kPa, 15.8 kPa, and 17.5 kPa, respectively; FS-LS had AUCs of 0.918, 0.878, and 0.939, respectively, in the diagnosis of F≥2, F≥3, and F=4 liver fibrosis, and the corresponding cut-off values were 10.1 kPa, 12.9 kPa, and 18.2 kPa, respectively; ARFI-LS had AUCs of 0.904, 0.869, and 0.928, respectively, in the diagnosis of F≥2, F≥3, and F=4 liver fibrosis, and the corresponding cut-off values were 1.45 m/s, 1.83 m/s, and 2.08 m/s, respectively. There was no significant difference in diagnosing the same stage of liver fibrosis between FibroTouch, FibroScan, and ARFI (P＞0.05). The multivariate analysis showed that degree of liver fibrosis (β=0.399, P＜0.001), total bilirubin (β=0.466, P＜0.001), and prothrombin time activity (β=-0.195, P=0.020) were influencing factors for FT-LS; degree of liver fibrosis (β=0370, P＜0.001), aspartate aminotransferase (β=0.450, P＜0.001), prothrombin time activity (β=-0.303, P=0.001), and alkaline phosphatase (β=-0.187, P=0.042) were influencing factors for FS-LS; degree of liver fibrosis (β=0.489, P＜0.001), aspartate aminotransferase (β=0.467, P＜0.001), and platelet count (β=-0.188, P=0.028) were influencing factors for ARFI-LS. ConclusionFibroTouch has similar efficiency to FibroScan and ARFI in the diagnosis of liver fibrosis in PBC patients, with relatively high diagnostic efficiency for significant liver fibrosis (F≥2) and liver cirrhosis (F=4), and therefore, it can be used as a reliable method for the diagnosis of liver fibrosis in PBC patients.

Objective:To observe the clinical efficacy of combining electroacupuncture with long needle sacral nerve acupuncture in the treatment of diabetic overactive bladder.Methods:A total of 90 patients with diabetic overactive bladder were randomly divided into an observation group and a control group, each of 45. In addition to the basic treatment for diabetes, the observation group received electroacupuncture combined with long needle sacral nerve acupuncture 5 times a week for 4 weeks, while the control group was given 5mg of oral solinax succinate once a day as a course of treatment. One week before the beginning of the experiment and one week before its end, urination diary cards were used to record the average number of times of daytime and nighttime urination daily, as well as any urgent urination and urinary incontinence during the week. Bladder overactivity syndrome score (OABSS), the bladder overactivity quality of life questionnaire (OAB-q), maximum urine flow rate (Qmax) and mean urine flow rate (Qave) were employed to quantify urination status, life quality and the urodynamics of the 2 groups before and after the treatment.Results:After the treatment, significant improvement was observed in the average weekly incidence of daytime and nighttime urination, of urgent urination and of urinary incontinence. The average OABSS, OAB-q, Qmax and Qave scores improved in both groups, but the experimental group showed significantly better improvement than the control group.Conclusion:Electroacupuncture combined with sacral nerve needling can significantly reduce the frequency of urination, relieve the symptoms of urgent urination and incontinence, and improve the rate of urine flow, improving the life quality of patients with diabetic overactive bladder.

Objective:To evaluate the value of Sonazoid contrast enhanced ultrasound (CEUS) in preoperative prediction of proliferating cell nuclear antigen 67 (Ki-67) level of hepatocellular carcinoma (HCC) by establishing predictive model based on radiomics features of Kupffer phase.Methods:From October 2020 to August 2021, patients with histologically confirmed HCC lesion and who underwent Sonazoid CEUS examination 1 week before surgery were prospectively enrolled. The radiomics signatures were extracted from the whole tumor region on gray scale images and Kupffer phase images. Two predictive radiomics models were constructed using radiomic method. The predictive performance of 2 models was compared.Results:A total of 50 patients with histologically confirmed single HCC lesions were prospectively enrolled in this study. Among them, histological results revealed 24 HCC lesions with high level representation of Ki-67 (>20%) and 26 HCC lesions with low level representation of Ki-67 (≤20%). Two radiomics predictive models were established based on gray scale images and Kupffer phase images respectively. While compared with model based on B-mode ultrasound images, model based on Kupffer phase images showed significantly higher area under receiver operating characteristic curve (0.753 vs 0.535, P=0.017), accuracy (0.720 vs 0.580, P=0.023) and sensitivity (0.458 vs 0.250, P=0.043). Calibration plot indicated that Kupffer phase model showed better consistency with the actual Ki-67 level than gray scale model. Conclusions:The radiomics model based on Kupffer phase features of Sonazoid CEUS is a preoperative and noninvasive prediction the presentation level of Ki-67 in HCC lesions.

Objective:To quantitatively evaluate the stiffness of pancreatic parenchyma and lesions by virtual touch tissue imaging and quantification (VTIQ) technique, and to investigate the potential usefulness of ultrasound shear wave elastography (SWE) in the prediction of clinically relevant post-operative pancreatic fistula (CR-POPF) after pancreatectomy.Methods:Patients who scheduled to receive pancreatectomy were prospectively enrolled in Zhongshan Hospital, Fudan University from March 2021 to December 2021. VTIQ assessment was applied to patients within one week before the scheduled surgery to make quantitative SWE evaluation of target tissue. The SWV values of body part pancreatic parenchyma and lesions were measured and recorded. The palpation stiffness of pancreas was qualitatively evaluated during the operation by the surgeon.CR-POPF was diagnosed according to 2016 International Study Group of Pancreatic Fistula (ISGPF) standard.Grade B/C pancreatic fistula was defined as CR-POPF positive. Recognized peri-operative risk factors of CR-POPF were analyzed. ROC curve analysis was used to evaluate the diagnostic efficacy of SWV value in predicting CR-POPF.Results:A total of 72 patients were finally enrolled in this study, including 47 (65.3%, 47/72) patients who received pancreaticoduodenectomy (PD) and 25 (34.7%, 25/72) patients who underwent distal pancreatectomy. CR-POPF occurred in 22 (30.6%, 22/72) patients after pancreatectomy. The SWV value of body part pancreatic parenchyma was significant lower in CR-POPF positive group than in CR-POPF negative group ( P<0.001). There was no significant difference in lesion SWV value between CR-POPF positive and negative groups ( P=0.664). Besides, the palpation stiffness was no difference between the two groups ( P=0.689). Taking SWV value of pancreatic parenchyma >1.16 m/s as a cut-off value for predicting CR-POPF, the area under the ROC curve (AUROC) was 0.816 with 0.760 of sensitivity, 0.634 of specificity, 67.5% of positive predictive value and 72.5% of negative predictive value, respectively. Conclusions:The VTIQ method may improve the objectivity and accuracy of CR-POPF prediction via pre-operative, non-invasive and quantitative evaluation of pancreatic stiffness, which has potential value in clinical applications.
