Purpose To evaluate the value of shear wave elastic imaging of liver and spleen in predicting high risk esophageal and gastric varices in cirrhosis.Materials and Methods Sixty-four patients with cirrhosis in the First Hospital of Lanzhou University from November 2019 to April 2022 were enrolled prospectively,and underwent gastroscopy,elastography and serological examination.According to gastroscopy,patients were divided into high-risk varices(HRV,30 cases)and non-HRV group(34 cases),the differences of each clinical index and shear wave elastic imaging parameter between the groups were compared.The diagnostic efficacy of liver and spleen stiffness measurement for HRV was analyzed.And the diagnostic models were established for exploring the diagnostic effectiveness of different models with respect to excluding HRV in compensated liver cirrhosis.Results There were significant differences in platelet[(74±24)×109/L vs.(124±50)×109/L],liver stiffness[(16.1±5.6)kPa vs.(13.6±5.5)kPa]and spleen stiffness[(41.7±8.9)kPa vs.(28.1±8.6)kPa]between HRV and non-HRV groups(t/Z/χ2=5.136,-1.832,-6.206,all P<0.05).The areas under the curve of liver stiffness and spleen stiffness for predicting HRV were 0.660 and 0.858,respectively.The Baveno Ⅵ combined with the spleen stiffness model had the best performance(30.0％)for excluding HRV.Conclusion The measurement of liver and spleen stiffness by shear wave elastography has great diagnostic value for predicting HRV in cirrhosis,and spleen stiffness is better than liver stiffness.

Objective:To investigate the clinical characteristics and structural and functional cardiac changes in heart failure with preserved ejection fraction(HFpEF)complicated with atrial fibrillation(AF)in elderly patients.Methods:As a cross-sectional study, 835 patients with HFpEF aged ≥60 years admitted to the Department of Geriatric Cardiovascular Medicine of the First Hospital of Lanzhou University between April 2009 and December 2020 were divided into an HFpEF+ AF group(267 cases)and an HFpEF group(568 cases)according to whether they had AF in addition to HFpEF, and their cardiac structure and function were evaluated.The optimal cutoff point of the ratio of the peak early diastolic velocity(E)to the maximum early diastolic velocity(e')of the mitral annulus(E/e')was analysed using the receiver operating characteristic(ROC)curve.The HFpEF+ AF group was divided into two subgroups, E/e'>11 and E/e'≤11, and differences in their clinical presentation, cardiac structural and function, and the relationship between the left and right heart were compared.Results:Compared with the HFpEF group, the left atrial volume index(LAVi)was larger[(60.0±23.3)ml/m 2vs.(43.9±19.0)ml/m 2, t=10.130, P<0.01]and the left ventricular ejection fraction(EF), mitral annular septal systolic velocity(s' S)and E/e' were smaller than in the HFpEF+ AF group(all P<0.01), whereas the right ventricular diameter(RVD), right atrial diameter(RAD)and area(RAA), tricuspid regurgitation velocity(TRv), and pulmonary arterial systolic pressure(PASP)in the HFpEF+ AF group were all greater than those in the HFpEF group(all P<0.05).In the E/e'>11 subgroup of HFpEF+ AF, the prevalence of hypertension, coronary heart disease and diabetes were higher, AF courses were shorter, and the decline of s' was more severe(all P<0.05).Furthermore, E/e' was independently correlated with LAVi, as was LAVi with PASP( t=2.114, 1.963, P=0.034, 0.042).The above-mentioned features were similar to those in the HFpEF group.The E/e'≤11 subgroup had a higher proportion of women, longer duration of AF than the E/e'>11 subgroup(median: 5 years vs.1 year, P=0.003), more noticeable enlargement of the right ventricle and right atrium, higher TRv and PASP( P<0.05). Conclusions:In elderly patients with HFpEF complicated with AF, the left atrial volume is increased further, and left ventricular systolic function and right heart morphology show serious deterioration, suggesting there might be two phenotypes of HFpEF+ AF with different pathophysiological mechanisms.

Objective: To investigate the effects of interleukin ( IL) -10 on the proliferation of HaCaT cells and CaCl2 induced expression of differentiation markers and its possible molecular mechanisms． Methods: HaCaT cells were treated with various concentrations of IL-10 (0，3，10，30 ng / ml) for different time (0，24，48，72 h) ，cell proliferation was measured using MTS，and cell cycle was determined by flow cytometry．HaCaT cells were pretreated with IL-10 (final concentration 10 ng / ml) for 1 h，then incubated with or without CaCl2 (final concentration 1. 2 mmol / L) for 24，48，72 h ，Western blot was performed to detect the effect of IL-10 on the expression of HaCaT keratinocyte differentiation markers．After pretreatment of HaCaT cells with PD98059，an inhibitor of mitogen-activated kinase-ERK1 /2，and LY294002，an inhibitor of phosphatidylinositol kinase-serine / threonine kinase (PI3K-AKT) ，the total RNA and proteins were extracted separately，real time quantitative polymerase chain reaction (RT-qPCR) and Western blot were used to examine the influence of IL-10 on the expression of differentiation markers (Keratin1，Keratin5，Involucrin) . Results : MTS results revealed that IL-10 (30 ng / ml and lower doses) did not alter the proliferation of HaCaT cells in 72 h．Flow cytometry analysis demonstrated that IL-10 had no significant influence on cell cycle progression．The results of Western blot showed that IL-10 upregulated the expression of differentiation markers Involucrin，while there was no significant effect on Keratin1 and Keratin5 ．Mechanism research analysis demonstrated that IL-10 could activate ERK1 /2 and AKT ，increase their phosphorylation levels ; RT-qPCR and Western blot results showed that PD98059 and LY294002 partially blocked IL-10 induced Involucrin expression． Conclusion At a particular concentration range，IL-10 has little effect on HaCaT proliferation ，but it partially upregulates the expression of differentiation marker Involucrin via the MAPKs-ERK1 /2 and PI3K-AKT pathways.

Objective:To explore the clinical effectiveness of hemostatic bandage on wound safety and comfort after transradial coronary angiography and/or interventional therapy.Methods:This was a experimental study. A total of 400 consecutive patients who underwent transradial coronary angiography and/or interventional therapy in the Department of Cardiology, Peking University Third Hospital from July to October 2022 were enrolled and randomly divided into the hemostatic bandage group and the hemostatic balloon compressor group by the envelope method with 200 cases in each group. The hemostatic bandage group and the hemostatic balloon compressor group were treated with hemostatic bandage and hemostatic balloon compressor as transradial artery hemostatic device, respectively, to observe and compare postoperative hemostatic effect, hemostat use time, complication rate, postoperative pain, the degree of numbness in the finger on the operated side and wristband comfort between the two groups.Results:The hemostatic success rate was 98.5% (197/200) and 99.0% (198/200) in the hemostatic bandage and the hemostatic balloon compressor group, respectively, with no statistical difference ( χ2=0.20, P>0.05). The hemostat use time in the hemostatic bandage group and the hemostatic balloon compressor group was (6.23 ± 0.47) h and (17.01 ± 7.74) h, respectively, and the difference was statistically significant ( t=-19.66, P<0.01). The incidence of complications in the hemostatic bandage group and the hemostatic balloon compressor group was 13.5%(27/200) and 29.5%(59/200), respectively, and the difference was statistically significant ( χ2=8.01, P<0.05). Among the complications, swelling occurred in 21 individuals of the hemostatic bandage group and 54 individuals of the hemostatic balloon compressor group with statistically significant differences ( U=16 689.50, P<0.01). Besides, the hemostatic bandage group was significantly better than the hemostatic balloon compressor group with statistically significant differences in wound pain at immediate postoperative ( U=13 669.50, P<0.01), in finger numbness at immediate postoperative and 1-hour postoperative (immediate postoperative: U=17 838.00, P<0.05; 1-hour postoperative: U=13 342.50, P<0.01), in comfort at immediate postoperative, 4-hours, 8-hours and 12-hour postoperative(immediate postoperative: U=9 966.50, P<0.01; 4-hour postoperative: U=12 851, P<0.01; 8-hour postoperative: U=14 900, P<0.01; 12-hour postoperative: U=15 920, P<0.01). Conclusions:The hemostatic bandage shows better hemostatic effect, shorter compression time, lower complication rate, less wound pain, less numbness of the finger on the operation side, and higher comfort of the wrist band compared to hemostatic balloon compressor after transradial coronary angiography and/or interventional therapy, which is worthy of clinical promotion.

Objective:To investigate the application effect of Press-Z-track-Turn (PZT) intramuscular injection on the extravasation, local reaction, local pain after injection and patient satisfaction after Fulvestrant injection.Methods:Used a self-controlled study, 63 patients who underwent bilateral intramuscular injection of Fluvastatin in the outpatient injection room of Tianjin Medical University Cancer Hospital from August to October 2022 were conveniently selected. The observation time was two treatment cycles after inclusion in this study. Before the injection of the first treatment cycle, a coin toss was used to randomly decide to use traditional intramuscular injection and PZT intramuscular injection method for injection and record. After 28 days, another injection method was used, with a total of 126 injections per injection method. Observed the extravasation of drug solution and local reactions at the injection site within 7 days after injection using two injection methods, as well as the pain and satisfaction of patients within 7 days after injection.Results:The extravasation rate of drug solution for the PZT intramuscular injection was 1.59% (2/126), which was lower than 7.14% (9/126) for the traditional intramuscular injection, and the difference was statistically significant ( χ2=4.66, P<0.05); the incidence of mild and moderate local reactions for the PZT intramuscular injection was 3.97% (5/126) and 1.59% (2/126), respectively, lower than that for the traditional intramuscular injection 11.11% (14/126) and 5.56% (7/126), and the difference was statistically significant ( χ2=8.26, P<0.05); the pain score of the PZT intramuscular injection was (2.08 ± 0.85) points, lower than that of the traditional intramuscular injection (5.03 ± 1.06) points, and the satisfaction score of the PZT intramuscular injection was (23.68 ± 1.64) points, higher than that of the traditional intramuscular injection (20.10 ± 2.58) points. The difference was statistically significant ( t=-17.24, 9.16, both P<0.01). Conclusions:PZT intramuscular injection can effectively reduce the overflow rate, the incidence of grade 1 and 2 local reactions and the degree of pain of patients, and improve patient satisfaction, which is worthy of clinical application.

We describe a case of fetal sacrococcygeal teratoma detected by ultrasound at 14 gestational weeks. The tumor was classified as "type Ⅰ" by ultrasonography combined with MRI. The cystic part accounted for over 60% of the mass before 26 weeks and ruptured spontaneously at 28 weeks. The size of the tumor was 12.8 cm×9.7 cm×12.3 cm at 36 +5 gestational weeks. A female newborn was born through cesarean section at 37 weeks of gestation and had the tumor removed surgically on the postnatal day 4. Postoperative follow-up showed that the neonate had a good prognosis without physiological dysfunction.

Objective:To explore the value of liver stiffness and spleen stiffness measured by two-dimensional shear wave elastography (2D-SWE) in predicting high-risk varices (HRV) with compensated cirrhosis patients.Methods:Seventy patients with compensated cirrhosis who attended the First Hospital of Lanzhou University from November 2019 to April 2022 were recruited. All patients underwent examinations of liver stiffness measurement (LSM) and spleen stiffness measurement (SSM) by 2D-SWE. Binary logistic regression was used to analyze the risk factors affecting the occurrence of HRV. The diagnostic performances of LSM, liver stiffness (by 2D-SWE)-spleen length-to-platelet (LSPS) score, and SSM in predicting HRV were compared.Results:SSM was not technically feasible in 6/70 (8.6%) patients due to small volume of spleen.Among 64 patients with compensated cirrhosis, 30/64 (46.9%) were HRV. Binary multivariate Logistic regression analysis showed that SSM and platelet counts were independent influencing factors for predicting HRV, with OR values of 1.126 ( P=0.006) and 0.971 ( P=0.039), respectively. The area under the receiver operating characteristic curve (AUC) of LSM, LSPS score, and SSM were 0.660, 0.828 and 0.858, respectively. The AUCs of SSM and LSPS score were significantly higher than that of LSM ( P<0.05), but there was no statistical difference between SSM and LSPS score ( P=0.608). Conclusions:LSM and SSM measured by 2D-SWE have high success rate. SSM and LSPS score have high value in predicting HRV in patients with compensated cirrhosis, and the diagnostic performances of the above two methods are significantly higher than that of LSM.

We describe a rare case of fetal mediastinal capillary hemangioma presenting as pleural effusion and a huge pleural occupying lesion during late pregnancy. The patient was admitted at 36 +3 weeks of gestation, with a fetal chest occupying lesion for 11 days. Routine prenatal ultrasound and MRI indicated right pleural effusion and a huge chest occupying lesion in the fetus. The woman was administered oxytocin and delivered a live baby boy at 36 +5 weeks of gestation. The baby was diagnosed as mediastinal hemangioma by postnatal CT, angiography and 3D reconstruction and was discharged after oral propranolol treatment. However, he was readmitted one month after birth due to "pneumonia and tachypnea". After multidisciplinary consultation, the baby underwent a right-side thoracic mediastinal mass resection, and a mediastinal capillary hemangioma was confirmed by pathology. The child continued taking propranolol orally and received regular follow-up and rehabilitation after the operation up to 7 months old, by which time no obvious abnormalities were found.
