Methods Seventeen patients with bladder neoplasms were treated with modified total cystectomy and Mainz Ⅱ neobladder for urinary diversion. The paries posterior allantois with intestinum rectum and colon sigmoideum were taken 10 cm respectively, split the mesenterium edges, conduplicated and bilayer sutured from the junction of intestinum rectum and colon sigmoideum, bilateral ureters antireflux anastomosed respectively with colon sigmoideum and rectal papilla, then bilayer sutured paries anterior became Mainz allantois. Results There was no surgical mortality. The operative time was 340 ～ 420 mins (mean, 350 mins).Blood transfusion was 400 ～ 800 ml ( mean 600 ml). The follow-up was 4 ～ 18 months, urine and dejecta were shunt, uresis continence was fine and the operation had fewer severe complications. Conclusion Modified total cystectomy and Mainz Ⅱ neobladder to be an effective method for urinary diversion because of its simple operation, fewer severe complications, good uresis continence and high quality of life.

The solvent extraction of rare earths with mixtures of di-( 2-ethylhexyl) phosphoric acid (D2EHPA,H2A2) and sec-nonylphenoxy acetic acid (CA100,H_2B_2) has been carried out. The separation abilities among rare earths were determined and compared with those with D_2EHPA alone. The mechanism of synergistic extraction of lanthanum was discussed. The methods of slope analysis and constant mole were used to examine the extraction stoichiometry. Effects of acidities,concentrations of extractants,and temperature on the extractabilities have been investigated. The results showed that the synergistic effects decrease with increasing atomic numbers of rare earths. At proper ratios of the extractants,the separation abilities of some rare earths with D2EHPA +CA100 were higher than those with D2EHPA alone,which may be applied to the separation of these rare earths. The extracted complex of lanthanum with D2EHPA + CA100 was determined as LaH5A6B2. The synergistic extraction is endothermically driven.

Objective:To evaluate the application value of left ventricular pressure-strain loop (PSL) in patients with rheumatoid arthritis (RA) by the PSL.Methods:From April 2020 to June 2021, 75 RA patients(case group) and 35 healthy physical examination person(control group) were selected from the Affiliated Hospital of Inner Mongolia Medical University.According to the disease activity scores 28(DAS28) joint disease range of activity score, the patients were divided into low range of activity group (16 cases), medium range of activity group (35 cases) and high range of activity group (24 cases). Echocardiographic examinations were performed on all patients, conventional ultrasound data were collected and the left ventricular PSL technology was used to analyze the myocardial work parameters, including global work index (GWI), global constructive work (GCW), global waste work (GWW) and global work efficiency (GWE). The mean values of myocardial work index (MWI), constructive work (CW), waste work (WW) and work efficiency (WE) were calculated. The differences of myocardial work parameters between the case groups and the control group were compared, and the correlation analysis of myocardial work parameters with global longitudinal strain of left ventricle(LVGLS), left ventricular ejection fraction(LVEF) and DAS28 scores were conducted.Results:①There were no statistically significant differences of clinical data between each case group and the control group (all P>0.05). ②Compared with the control group and low disease activity group, the LVGLS of medium and high disease activity groups decreased obviously (all P<0.05). ③The GWI and GCW of the medium and high disease activity groups were significantly lower than those of the control group (all P<0.05), and there were no statistically significant differences of GWW and GWE between the case groups and the control group (all P>0.05). The mid-segment MWI, apical MWI and CW of the medium and high disease activity case groups, and the mid-segment CW of the medium disease activity case group were lower than those of the control group (all P<0.05). ④In the case group, GWI, GCW and LVEF were significantly and positively correlated ( rs1=0.253, P=0.008; rs2=0.261, P=0.024), and were significantly negatively correlated with LVGLS ( rs1=-0.525, P<0.001; rs2=0.455, P<0.001). There were no significant correlations between myocardial work parameters and DAS28 score (all P>0.05). Conclusions:PSL can early reflect to the impaired cardiac function of RA patients with moderate and high disease activity, and provide a new imaging method for clinical evaluation of the cardiac function of patients.

Objective:To evaluate the cardiac function and systolic dyssynchrony of fetuses exposed to maternal autoimmune antibodies (anti-SSA/Ro60, anti-SSA/Ro52 and anti-SSB/La) by using two-dimensional speckle tracking imaging (2D-STI).Methods:A total of 52 pregnant women with singleton pregnancy in the Affiliated Hospital of Inner Mongolia Medical University from July 2018 to November 2020 were selected. Eighteen fetuses of mothers with autoimmune antibodies were enrolled as autoimmune disease (AD) group and 34 fetuses of healthy mothers without antibodies were included as control group. Maternal baseline characteristics, fetoplacental Doppler parameters, and conventional echocardiographic data of two groups were prospectively collected. The systolic global and regional longitudinal strain of left and right ventricles (LV and RV) and the time to peak strain of regional myocardium were measured using 2D-STI. The differences in time to peak strain between the LV free wall and RV free wall (two-chamber dyssynchrony, 2C-DYS) and between the septum and LV free wall (one-chamber dyssynchrony, 1C-DYS) were also calculated.Results:There were no significant differences between the two groups in conventional systolic and diastolic functional parameters for the LV and RV(all P>0.05). The myocardial deformation parameters and 2C-DYS obtained by 2D-STI showed no statistical differences between two groups(all P>0.05). However, 1C-DYS was significantly more prolonged in the AD group than control group[28.50(13.50, 39.25)ms vs 19.50(8.00, 29.25)ms, P=0.042]. Conclusions:LV systolic mechanical dyssynchrony in fetuses of mothers with autoimmune antibodies suggests in-utero subclinical damage of the cardiac conduction system.

Objective:To observe the feasibility of evaluating right ventricular (RV) function by the method based on left ventricle (LV) pressure-strain ring (PSL) technique in patients with systemic lupus erythematosus (SLE), and to evaluate the efficacy of non-invasive PSL in the diagnosis of dysfunction of both LV and RV.Methods:Thirty-nine patients were enrolled with SLE who were admitted to the Affiliated Hospital of Inner Mongolia Medical University from March 2020 to September 2021 and 57 sex- and age-matched healthy controls underwent assessment by conventional echocardiography, two-dimensional speckle tracking imaging (2D-STI) and myocardial work (MW). The echocardiographic parameters were compared between the groups. The correlations between RVMW parameters and conventional echocardiographic parameters, and between MW parameters and SLEDAI-2K score were analyzed by Spearman correlation analysis.Results:①The two groups did not show any difference at the conventional echocardiographic parameters of the LV systolic function ( P>0.05). In the SLE group, tricuspid regurgitation maximal velocity (TR V max) and right ventricular index of myocardial performance (RIMP) increased, tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular S′ (S′ tv) decreased (all P<0.05), and others did not show statistical difference (all P>0.05). ②The 2D-STI parameters: There were no significant differences in left ventricular global longitudinal strain (LV GLS) ( P>0.05), however RVGLS decreased ( P<0.05). ③The MW parameters of LV and RV: including global constructive work (GCW), global work index (GWI), global wasted work (GWW), and global work efficiency (GWE). In SLE group, LV GWE, RV GWE decreased and LV GWW, RV GWW increased ( P<0.05), others were no significant differences ( P>0.05). ④The correlation analysis: RV GWI positively correlated with TR V max ( rs=0.481). RV GCW positively correlated with TR V max ( rs=0.587). RV GWW positively correlated with right atrial area (RAA) and TR V max ( rs=0.429, 0.610), negatively correlated with S′ tv ( rs=-0.342). RV GWE positively correlated with S′ tv ( rs=0.326) and negatively correlated with RAA ( rs=-0.462) (all P<0.05). SLEDAI-2K score was negatively correlated with LV GLS ( rs=-0.333) and LV GWI ( rs=-0.326) ( P<0.05). Conclusions:The study has shown the impaired systolic function of both LV and RV in patients with SLE. PSL technique, especially RVMV based on LV PSL technique might emerged as a novel measure to evaluate systolic dysfunction in SLE patients.
