Objectives:To evaluate the clinical value of the Paris system for reporting urinary cytology (TPS) in the diagnosis of urothelial carcinoma (UC).Methods:A total of 1 744 cytological diagnostic records (from 751 cases) were collected retrospectively. All specimens were voided urines and histopathology as the gold standard. The sensitivity and specificity of urinary cytological diagnosis of UC and risk of high grade malignant (ROHM) in each diagnostic category were compared.Results:There were 360 cases with histopathology. The percentage of negative for high-grade urothelial carcinoma (NHGUC) was 30.1% (226/751), atypical urothelial cells (AUC) was 29.8% (224/751), suspicious for high-grade urothelial carcinoma (SHGUC) was 16.8% (126/751), high grade urothelial carcinoma (HGUC) was 21.2% (159/751), and non-urothelial malignancy (NUM) was 2.1% (16/751). The histpathologic ROHM corresponding to each cytological diagnosis category were 27.3% for NHGUC, 32.7% for AUC, 74.7% for SHGUC, 96.6% for HGUC and 100.0% for NUM, respectively. ROHM of SHGUC was significantly higher than that of AUC group, and the difference between the two groups was statistically significant ( P＜0.001). ROHM of HGUC group was significantly higher than that of SHGUC group, and the difference was statistically significant ( P＜0.001). With SHGUC as the cut-off value, the sensitivity and specificity of cytological diagnosis of HGUC were 76.7% (165/215) and 85.7% (18/21), and with HGUC as the cut-off value, the sensitivity and specificity of cytological diagnosis of HGUC were 53.0% (114/215) and 100.0% (21/21), respectively. Conclusions:Urine cytology has high sensitivity and specificity in the diagnosis of HGUC. The malignant risk of TPS varies with different diagnosis category. The high malignant risk population in cancer hospital leads to the relatively high malignant proportion and ROHM in each diagnosis category. Urinary cytology TPS reporting system is helpful to clinical management and has good clinical application value.

Parkinson's disease(PD)is the most common neurodegenerative disease in middle-aged and elderly people.Constipation is one of the most common non-motor symptoms of PD.Anorectal manometry can objectively reflect anorectal movement and sensory function,and is one of the necessary tests to check anorectal function,judge the type of constipation,and evaluate the effect of constipation treatment.This paper expounds the detection indicators and significance of anorectal manometry,and summarizes the characteristics of anorectal manometry in PD patients with constipation:decreased maximum anal systolic pressure,insufficient rectal propulsion,decreased rectal sensitivity,and the type of constipation in PD patients is mainly outlet obstruction with contradictory anal contraction or insufficient relaxation during defecation.

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 report on the clinical characteristics of a family of short-rib polydactyly syndrome type III and its pathogenic variants. METHODS: Muscle samples from the the third fetus was collected after the induction of labor, and peripheral blood samples of its parents and grandparents were also collected. Whole exome sequencing (WES) was carried out for the pedigree. Candidate variants were verified by Sanger sequencing of the family. RESULTS: The proband was found to harbor a c.9819+1G>A variant and a c.4625C>A variant of the DYNC2H1 gene, which were respectively inherited from its mother and father. Sanger sequencing verified that the family has fit the autosomal recessive inheritance. CONCLUSION The c.9819+1G>A and c.4625C>A variants of the DYNC2H1 gene probably underlay the short-rib polydactyly syndrome type 3 in the proband.

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.

Autoantibody-related congenital heart block (ACHB) is a passively acquired autoimmune disease developing in fetuses after exposuring to maternal anti-Ro/Sj?gren's syndrome type A (SSA) antibody and/or anti-La/SSB antibody transported across the placenta, which contributes to fetal heart conduction system damage and signal conduction block at the atrioventricular node. However, fetal atrioventricular block does not necessarily occur with the presence of maternal autoantibodies, indicating its complex pathogenesis. This review focuses on the theories of calcium channels and apoptosis, the influence of other maternal factors and environmental changes on ACHB and the roles of natural killer cells and human leukocyte antigen in ACHB, aiming to provide reference for further study on the pathogenesis.

As for the treatment of microtia, the status quo is as follows. The ear reconstruction with autologous costal cartilage has been generally accepted as the therapeutic strategy for type Ⅲ/Ⅳ patients with only small ear lobe remaining or complete absence of auricle, and the outcomes are improved steadily with the advances in technology; but for type Ⅰ/Ⅱ patients with larger remnant ear, there is insufficient evidence to be able to support any specific treatment methods as the potential unified approach for surgeons to choose from. Non-surgical treatment with appliance wearing may play an auxiliary role in the treatment of microtia, which is worthy of further research. The authors proposed a serialized treatment system based on their clinical practice and literature review. It is expected to be helpful for the treatment of microtia.
