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.

Objective:To evaluate the utility of the 9-gene panel as a differential diagnostic method for thyroid nodules within determinate cytological diagnosis and as a parallel diagnostic method for thyroid fine-needle aspiration (FNA) cytology.Methods:579 liquid-based cytology samples from 544 patients were collected after thyroid FNA diagnosis in our hospital from December 2014 to April 2021. Mutations at any site of 9 genes, namely, BRAF, NRAS, HRAS, KRAS, GNAS, RET, TERT, TP53, and PIK3CA as recorded by the Catalogue of Somatic Mutations in Cancer (COSMIC), were analyzed by next-generation sequencing. Taking postoperative histopathology and cytology results with definite benign or malignant diagnosis as the gold standard, the diagnostic efficacy of the 9-gene panel as a reclassified method for thyroid nodules with indeterminate cytological diagnosis and as a parallel diagnostic method for thyroid FNA cytology were evaluated and compared with that of the BRAF V600E single-gene detection method.Results:Of the 579 thyroid nodules, 196 (33.85%) were Bethesda Ⅱ, 11 (1.90%) were Bethesda Ⅲ, 31 (5.35%) were Bethesda Ⅳ, 27 (4.66%) were Bethesda Ⅴ, and 314 (54.23%) were Bethesda Ⅵ, as diagnosed by thyroid FNA cytology. Among these 579 thyroid nodules, 275 were tested positive for 9-gene mutations, with a mutation rate of 47.5%. Of the 329 thyroid nodules surgically removed, 30 (9.12%) were benign, 5 (1.52%) were borderline, and 294 (89.36%) were malignant. Regarding borderline nodules as malignant nodules, the mutation rates of the 9 genes in the 299 malignant thyroid nodules from high to low were BRAF 62.21% (186/299), NRAS 5.02% (15/299), HRAS 1.00% (3/299), PIK3CA 0.67% (2/299), GNAS 0.67% (2/299), KRAS 0.33% (1/299), TP53 0.33% (1/299), TERT 0.33% (1/299) and RET 0.00% (0/299). The malignant risks of the 9 genes from high to low were BRAF 100% (186/186), PIK3CA 100.00% (2/2), GNAS 100.00% (2/2), TERT 100.00% (1/1), TP53 100.00% (1/1), NRAS 78.95% (15/19), HRAS 75.00% (3/4), and KRAS 50.00% (1/2). For thyroid nodules of Bethesda Ⅲ-Ⅳ (indeterminate diagnosis), the sensitivity (SN) of the 9-gene panel in diagnosing thyroid cancer is 34.48% (10/29), the specificity (SP) is 61.54% (8/13), and the accuracy is 42.86% (18/42); whereas the SN of the BRAF V600E detection method is 0%. Therefore, the diagnostic efficiency of the 9-gene panel is significantly better than that of BRAF V600E single gene detection. For thyroid nodules of Bethesda Ⅱ-Ⅵ, the SN of the 9-gene panel in diagnosing thyroid cancer was 68.83% (254/369), the SP was 90.00% (189/210), the accuracy was 76.51% (443/579), and the area under the curve (AUC) was 0.79; whereas the SN of BRAF V600E single-gene detection in diagnosing thyroid cancer was 63.69% (235/369), the SP was 99.52% (209/210), the accuracy was 76.68% (444/579), and the AUC was 0.82. The SP of BRAF V600E detection is higher than that of the 9-gene panel ( P<0.01), but there is no significant difference in SN, accuracy (both P>0.05), and AUC ( Z=0.85, P=0.396) between them. Gene mutations indicating poor prognosis were detected in 4 nodules of papillary thyroid carcinoma and 1 nodules of follicular thyroid carcinoma, including 2 nodules with TERT and BRAF V600E co-mutations, 1 nodule with TP53 mutation, and 2 nodules with PIK3CA mutation. Conclusions:As a reclassified method for thyroid lesions with indeterminate cytological diagnosis, the 9-gene panel is better than BRAF V600E single gene detection. As a parallel diagnostic method of thyroid FNA cytology, the 9-gene panel has similar diagnostic efficacy as BRAF V600E single-gene detection. The 9-gene panel can detect individual cases with gene mutations indicating poor prognosis. The identification of patients with these special gene mutations has certain implications for the clinical management of them.

6.Evaluation and management of heart failure with arrhythmias in children
Chinese Pediatric Emergency Medicine 2023;30(1):19-24
Heart failure is the end-stage clinical manifestation of various functional or structural heart diseases, which is an acute and critical condition in the field of pediatrics.Arrhythmias are often complicated with heart failure in children and could also trigger heart failure exacerbation, affecting the prognosis of children.The clinical manifestations of arrhythmias in children are atypical except the malignant types, and children with heart failure should always be alerted to the possibility of arrhythmias.Therefore, it is important for improving the prognosis of children with heart failure by raising awareness of these diseases, thus making a rational assessment of disease and actively managing it.

Objective:To investigate the effect of drug therapy on heart failure caused by supraventricular tachycardia(SVT) in infants.Methods:Fifty-five infants with heart failure caused by SVT, including 24 boys and 31 girls, were treated at Beijing Children′s Hospital of Capital Medical University from January 2014 to December 2021.The drug treatment effects of heart failure caused by SVT were analyzed.Results:The average age of 55 infants at the first diagnosis was 5.8 months(1-11 months). All of them had heart failure, including three cases of atrial flutter, 23 cases of atrial tachycardia(13 cases of disordered atrial tachycardia and ten cases of monomorphic atrial tachycardia), and 29 cases of paroxysmal supraventricular tachycardia.Ultrasonic cardiogram showed that the left ventricular diameter increased and/or left ventricular systolic function decreased.Anti-heart failure therapy was effective in 55 cases(100.0%). Anti-arrhythmic drug therapy: atrial flutter and atrial tachycardia were mainly treated by controlling ventricular rate, digitalis combined with metoprolol was effective in 21 cases(80.8%, 21/26), digitalis alone was effective in four cases(15.4%, 4/26), and sotalol was effective in one case(3.8%, 1/26); paroxysmal supraventricular tachycardia was mainly treated with sinus rhythm conversion.The success rates of conversion were: ATP 20.7%(6/29), ATP combined with digitalis 26.1%(6/23), propafenone combined with digitalis 42.9%(3/7), amiodarone combined with digitalis 60.0%(3/5), and sotalol 92.9%(12/13). During follow-up period for 1 to 12 months, heart failure symptoms of all 55 cases(100.0%) improved, and ultrasonic cardiogram of 53 cases(96.3%)returned to normal.Conclusion:Anti-heart failure and anti-arrhythmic drugs for infants with heart failure caused by SVT need to be selected individually.Atrial tachycardia, especially disordered atrial tachycardia, is sensitive to digitalis.Sotalol can be used to treat refractory SVT.

Objective:To investigate the molecular genetic etiology of two fetuses with short rib-polydactyly syndrome type Ⅲ (SRPS Ⅲ).Methods:Next-generation sequencing (NGS) was used to detect 226 known genes related to inherited skeletal dysplasia in two fetuses with SRPS Ⅲ diagnosed in the First Affiliated Hospital of Zhengzhou University in August 2015 and June 2020. Suspect pathological variants were verified in the pedigree members using Sanger sequencing. The prenatal genetic diagnosis of the high-risk fetus in pedigree one was conducted to identify the confirmed pathogenic variation.Results:The homozygous mutation of DYNC2H1 gene c.5881A>G(p.Lys1961Glu) was identified in the proband in pedigree one, and the parents were the carriers. The proband in pedigree two carried compound heterozygous mutations in the DYNC2H1 gene with c.10606C>T(p.Arg3536*) inherited from the father and c.8954T>G(p.Val2985Gly) from the mother. Autosomal recessive inheritance was confirmed in both pedigrees. Mutations of c.5881A>G(p.Lys1961Glu) and c.8954T>G(p.Val2985Gly) in the DYNC2H1 gene were likely pathogenic variants and had not been reported before. The prenatal diagnosis did not identify the DYNC2H1 gene c.5881A>G(p.Lys1961Glu) mutation in the fetus (Ⅱ-7) in pedigree one, which was confirmed by the umbilical cord blood sample after birth. Conclusion:DYNC2H1 gene mutation underlies the fetal skeletal dysplasia in the two pedigrees.

Objective:To evaluate the clinical effect of Guanxin Tongmai plaster combined with conventional western medicine in the treatment of phlegm and blood stasis syndrome of coronary heart disease and angina pectoris.Methods:A total of 60 patients in the Department of Cardiology of the Affiliated Hospital of Liaoning University of Traditional Chinese Medicine (TCM) from February to August 2020 who met the inclusion criteria were randomly divided into two groups with 30 in each group. Both groups were treated with conventional western medicine. On this basis, Guanxin Tongmai plaster was applied at the acupoints in the treatment group and placebo plaster was applied in the control group. TCM syndrome score was performed before and after treatment, angina score was evaluated from three aspects of angina attack frequency, duration and pain degree, and blood lipid TG, TC, LDL-C and HDL-C were detected by enzyme quantitative method. The blood homocysteine (Hcy) was detected by enzyme circulation method, the ECG and the nitroglycerin reduction rate were recorded, and the safety index was detected according to the ECG changes.Results:In the treatment period, 2 patients in the treatment group fell off, 3 in the control group. A total of 28 patients in the treatment group and 27 in the control group were analyzed. The total effective rate of ECG efficacy in the treatment group was 67.9% (19/28) and the control group was 48.1% (13/27). There was significant difference between the two groups ( χ2=4.46, P=0.040). After treatment, the TCM syndrome score and angina score in the treatment group were significantly lower than those in the control group ( t values were 9.12 and 4.45, P values were 0.004 and 0.042, respectively). The reduction rate of nitroglycerin in the treatment group was 82.1% (23/28) and 55.6% (15/27) in the control group. There was significant difference between the two groups ( χ 2=4.72, P=0.030). After treatment, the plasma TG, TC, LDL-C in the treatment group were significantly lower than those in the control group ( t values were 4.17, 6.57 and 6.52, P<0.05 or P<0.01), the level of HDL-C was significantly higher than that of the control group ( t=7.07, P=0.010), and the level of plasma Hcy was significantly lower than that in the control group ( t=6.70, P=0.012). There was no significant difference in liver, kidney and coagulation function between the two groups. Conclusion:Guanxin Tongmai plaster combined with conventional western medicine can improve the clinical symptoms of patients with coronary heart disease and angina pectoris, reduce the level of blood lipid and Hcy, and improve the clinical curative effect.

OBJECTIVE:
To explore the genetic basis for a child featuring congenital insensitivity to pain (CIP).
METHODS:
Targeted capture and next generation sequencing (NGS) was carried out for the proband. Suspected pathogenic variants were confirmed by Sanger sequencing of the proband and his parents.
RESULTS:
The proband was found to harbor compound heterozygous variants of SCN9A gene, namely c.1598delA (p.N533Ifs*31) and c.295_296delCGinsAT (p.R99I), which were respectively inherited from his father and mother. Both variants were predicted to be pathogenic, and neither was reported previously.
CONCLUSION
The compound heterozygous variants of the SCN9A gene probably underlay the CIP in this child. Above finding has enabled genetic counseling for this family.
