【Objective】 To investigate the prognostic value of tumor location in patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU), and to develop and validate a nomogram model for predicting the overall survival (OS). 【Methods】 UTUC patients undergoing RUN at our hospital during Jan.2010 and Dec.2022 were retrospectively collected, 70% of whom were included in the training group and 30% in the validation group.According to the tumor location, patients were divided into renal pelvis tumor (RPT) group and ureteral tumor (UT) group.The differences in clinicopathological features and prognosis were analyzed.Based on multivariate Cox results, a nomogram model for predicting OS was developed and validated. 【Results】 A total of 366 patients (196 RPT and 170 UT) were included in this study.There were statistically significantly differences in urine cytology (P=0.001), hydronephrosis (P<0.001), history of bladder tumor (P=0.021), pathological T stage (P<0.001) and histological structure (P=0.037) between the two groups.Multivariate Cox results showed that patients with UT had a worse prognosis (HR=2.00, 95%CI: 1.22-3.27, P=0.006).Factors of the nomogram for predicting OS included age, tumor location, lymphovascular invasion and pathological T stage.The model showed good discrimination and calibration, and performed well in internal verification. 【Conclusion】 Compared with RPT, UT has a worse prognosis and the fat around the tumor should be surgically removed more thoroughly to avoid micro-residual.We successfully coustructed a nomogram model that can be used to predict the OS of UTUC patients after RNU surgery.

Objective To evaluate the value of systemic inflammatory markers(SIM)in the prognosis of patients with bladder cancer undergoing radical cystectomy.Methods Clinical data of 233 patients with bladder cancer who underwent radical cystectomy in the Affiliated Hospital of Xuzhou Medical University during Dec.2011 and Nov.2020 were retrospectively collected,the SIM score was calculated and patients were grouped.Progression-free survival(PFS)was assessed with Kaplan-Meier analysis,and differences between groups were compared with log-rank test.Factors affecting PFS were analyzed with Cox proportional risk model.The patients were randomly divided into a training set(n=164)and a verification set(n=69)according to 7:3 ratio,and a nomogram model was established and verified.Results Cox regression analysis showed that SIM score and pathological T staging were independent predictors of PFS(P＜0.05).A predictive model was established based on SIM score and pathological T staging.The area under the receiver operating characteristic(AUC)curve for predicting 1-year,3-year,and 5-year PFS were 0.939,0.943,and 0.943,respectively.After the model was applied to evaluate the validation set,the performance was still stable.Conclusion The prediction model based on SIM score and clinicopathological T staging can accurately predict the survival of patients with bladder cancer after radical cystectomy,and can be used to guide individualized treatment of patients.

[Objective] To construct a Nomogram model for the prediction of essential hypertension (EH) risks with the use of traditional Chinese medicine (TCM) syndrome elements principles in conjunction with cutting-edge biochemical detection technologies. [Methods] A case-control study was conducted, involving 301 patients with essential hypertension in the hypertensive group and 314 without in the control group. Comprehensive data, including the information on the four TCM diagnoses, general data, and blood biochemical indicators of participants in both groups, were collected separately for analysis. The differentiation principles of syndrome elements were used to discern the location and nature of hypertension. One-way analysis was carried out to screen for potential risk factors of the disease. Least absolute shrinkage and selection operator (LASSO) regression was used to identify factors that contribute significantly to the model, and eliminate possible collinearity problems. At last, multivariate logistic regression analysis was used to both screen and quantify independent risk factors essential for the prediction model. The “rms” package in the R Studio was used to construct the Nomogram model, creating line segments of varying lengths based on the contribution of each risk factor to aid in the prediction of risks of hypertension. For internal model validation, the Bootstrap program package was utilized to perform 1000 repetitions of sampling and generate calibration curves. [Results] The results of the multivariate logistic regression analysis revealed that the risk factors of EH included age, heart rate (HR), waist-to-hip ratio (WHR), uric acid (UA) levels, family medical history, sleep patterns (early awakening and light sleep), water intake, and psychological traits (depression and anger). Additionally, TCM syndrome elements such as phlegm, Yin deficiency, and Yang hyperactivity contributed to the risk of EH onset as well. TCM syndrome elements liver, spleen, and kidney were also considered the risk factors of EH. Next, the Nomogram model was constructed using the aforementioned 14 risk predictors, with an area under the curve (AUC) of 0.868 and a 95% confidence interval (CI) ranging from 0.840 to 0.895. The diagnostic sensitivity and specificity were found to be 80.7% and 85.0%, respectively. Internal validation confirmed the model’s robust predictive performance, with aconsistency index (C-index) of 0.879, underscoring the model’s strong predictive ability. [Conclusion] By integrating TCM syndrome elements, the Nomogram model has realized the objective, qualitative, and quantitative selection of early warning factors for developing EH, resulting in the creation of a more comprehensive and precise prediction model for EH risks.

Objective:Combined with the actual clinical situation, to introduce the application of invasive trans super minimal intercostal device closure in doubly committed ventricular septal defect(DCVSD).Methods:Between January 2017 and July 2020, 82 DCVSD children were recruited. Relevant data such as operation time, length of hospital stay, postoperative complications, etc. were analyzed, and the follow-up of the postoperative period was used to evaluate the effect of the operation.Results:Among them, 2 children’s puncture points were bleeding. Chest closure time was obviously extended. The total operation time of the remaining children was 24-72(47.54±12.06)min, among which the umbrella release time was 5-37(16.16±8.01)min, and the chest opening and closing time was 14-59(31.56±9.58) min. Pericardial effusion occurred in 2 patients after operation, and the discharge time was more than 2 weeks. The remaining children were hospitalized for 3-9(5.79±1.45)days after surgery.Conclusion:Closing DCVSDs through a super minimal intercostal incision under TEE guidance was safe, effective and less trauma.

Objective    To explore risk factors associated with mortality and restenosis after the surgery for congenital pulmonary venous stenosis (CPVS) combined with congenital heart disease. Methods    From May 2007 to August 2019, 58 patients received surgical relief of CPVS combined with congenital heart disease, including 24 males and 34 females, aged 17.2±26.3 months, weighing 8.8±8.2 kg. Endpoints were death and restenosis, and the risk factors were analyzed. A univariate and multivariate risk analyses were performed. Results    Preoperative pulmonary venous stenosis severity score (PVSSS) was 4.5±2.7. Average pulmonary vein counts with CPVS was 1.9±1.0. There were 2 (3.4%) early deaths. The mean follow-up time was 2-145 (49.8±40.0) months. The 1-, 2-, 3- and 5-year overall survival rates were 86.7%, 81.3%, 78.5% and 73.6%, respectively, and the pulmonary venous restenosis-free rates were 79.6%, 68.5%, 68.5% and 68.5%, respectively. Preterm birth was an independent risk factor for mortality. The pulmonary venous peak flow rate ≥ 1.2 m/s at discharge was an independent risk factor for mortality and restenosis. Conclusion    The prognosis of CPVS is still poor. Postoperative residual stenosis at discharge is an independent risk factor for death and restenosis.

Long non-coding RNAs (lncRNAs) are a kind of transcripts which are longer than 200nt and have not protein-coding ability due to the lack of an open reading frame. However, lncRNAs can be involved in tumorigenesis and progression in various ways at the transcriptional and post-transcriptional levels. Bladder cancer associated transcript 1 (BLACAT1) as a lncRNA located on human chromosome 1q32.1, is ectopic expression in various tumors (bladder cancer, gastric malignant tumor, lung carcinoma, et al) and can regulate tumor cell proliferation, anti-apoptosis, invasion and metastasis by different mechanisms leading to occurrence and development of tumors. In this review, we summarized current studies of the functions and mechanisms of BLACAT1 in malignant tumors.

Objective: To assess the feasibility and efficacy of a staged invasive treatment strategy for the treatment of pulmonary atresia with intact ventricular septum, in the first stage using a catheter-based stent placement, second-stage surgery, and three-stage atrial septal occlusion. Methods: Totally 19 children with pulmonary atresia with intact ventricular septum were enrolled at Department of Cardiovascular Surgery, the Children′s Hospital of Zhejiang University School of Medicine from January 2009 to December 2017, including 11 male and 8 female patients. The age was (13.8±7.7) days (ranging from 3 to 35 days). The weight was (3.4±0.5) kg (ranging from 2.8 to 4.1 kg). Among them, there were 13 cases of type Ⅱ and 6 cases of type Ⅲ. Regular follow-up visits for patients with stage Ⅰ arterial duct stenting after 1, 3, and 6 months; and routine follow-ups for 1, 3, and 6 months after stage Ⅱ surgery.The t test was used to compare the oxygen saturation between pre-operation and post-operation. Results: All 19 patients underwent arterial catheterization. The preoperative peripheral oxygen saturation was (64.4±5.3)%, while increased to (86.0±3.0)% after operation (t=16.353, P=0.000). One patient died during follow-up and 2 patients lost follow-up. One patient received stent balloon dilatation due to oxygen saturation decrease.Twelve patients completed the second-stage surgery and 1 case died after surgery. The rest were alive, including 2 cases of double-ventricular correction and 9 cases of semi-ventricular treatment in one room; 2 cases had completed three-stage atrial septal occlusion. Conclusions Stage Ⅰ arterial duct stent, stage Ⅱ surgery, and stage Ⅲ atrial septal occlusion to treat pulmonary atresia with intact ventricular septum in children is feasible and effective. The method can be used as the important treatment direction for pulmonary atresia with intact ventricular septum.
