Background: Richter's syndrome (RS) defines the transformation of chronic lymphocytic leukemia into high-grade lymphoma, which usually involves lymph nodes and bone marrow. Extranodal involvement of the heart is an extremely rare condition. Patients with heart involvement tended to have a low response to chemotherapy and relative poor prognosis.

The regioselective [3 + 2] cycloaddition reaction of 2-benzylidene-1-indenones with functional olefins was established with DABCO as a base under mild conditions. Using this approach, a series of diversely substituted indanone-fused cyclopentane polycycles with highly crowded multiple substituents were synthesized in high yields.

Spinal muscular atrophy (SMA) is a rare hereditary neuromuscular disease with a high lethality rate in infants. Variants in the homologous genes survival of motor neuron (SMN)1 and SMN2 have been reported to be SMA pathogenic factors. Previous studies showed that a high inclusion rate of SMN2 exon 7 increased SMN expression, which in turn reduced the severity of SMA.

To compare pregnancy outcomes between patients with gestational diabetes mellitus (GDM) with and without their own blood glucose meter.We conducted a retrospective-cohort study of 835 women with GDM at the Second Hospital of Tianjin Medical University, Tianjin, China from 1 January 2016 to 31 December 2018. Perinatal outcomes of these patients were monitored and collected in the Tianjin Maternal and Child Health System.

Perceiving pitch is a central function of the human auditory system; congenital amusia is a disorder of pitch perception. The underlying neural mechanisms of congenital amusia have been actively discussed. However, little attention has been paid to the changes in the motor rain within congenital amusia.

Purpose: Myocardial ischemia/reperfusion injury (IRI) induces cardiomyocytes death and leads to loss of cardiac function. Circular RNAs (circRNA) have gain increasing interests in modulating myocardial IRI. In this study, we aim to investigate the role and exact mechanism of circTLK1 in the pathogenesis of myocardial IRI.

The present study focused on exploring the inhibitory mechanism of microRNA (miR)-23a in endometrial cancer. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used to investigate miR-23a expression in endometrial tissues and endometrial cancer cells. A colony formation assay using crystal violet staining was performed to compare cell proliferation, while wound-healing and Transwell assays were performed to compare cell migration and invasion.

Background: Cervical cancer is the most common gynecological malignancy with low terminal cure rate, and therefore new therapeutic targets are urgently needed to combat this disease. SMYD2, as an oncogene, is abnormal highly expressed in multiple types of tumors and further affects the occurrence and development, but the potential correlations between SMYD2 expression and cervical cancer progression is still unclear.

Methods: We first used the bioinformatics website to screen the data of cervical cancer in (The Cancer Genome Atlas) TCGA and survival analysis was used to find the different survival rates in the SMYD2 high expression group and low expression group.

Cervical cancer is one of the most common malignant neoplasms in gynecology. Protein tyrosine kinase 7 (PTK7) with an inactive kinase domain is an important regulator of multiple Wnt pathways under normal and various pathological conditions and overexpressed in various tumors; however, the clinical and biological significance of PTK7 in cervical cancer is still unknown. In the present study, the protein expression level of PTK7 was detected in clinical cervical cancer patient samples, and the relationship between PTK7 expression and clinicopathological features was analyzed.

Background: Myocardial infarction (MI) is a common cardiovascular disease caused by myocardial ischemia. Also, microRNA (miRNA) participates in the pathophysiology of many cardiovascular diseases, which can affect stem cell transplantation in the treatment of MI. In this study, our aim is to explore effect of miR-26b on inflammatory response and myocardial remodeling through the MAPK pathway by targeting PTGS2 in mice with MI.

Cardiac rupture and ventricular remodeling are recognized as the severe complications and major risk factors of acute myocardial infarction (AMI). This study aims to evaluate the regulatory roles of interleukin-1 receptor-associated kinase 3 (IRAK3) and nuclear factor-κB (NF-κB) signaling pathway in cardiac rupture and ventricular remodeling. Microarray analysis was performed to screen AMI-related differentially expressed genes and IRAK3 was identified.

Objective: To compare the advantages and disadvantages of the Foley catheter draining method versus the urethral stent plus gastric tube draining method for urine drainage following urethroplasty for hypospadias.

Methods: We retrospectively analyzed the clinical data of 361 cases of hypospadias treated by urethroplasty. After operation, 91 of the cases received urine drainage with the Foley catheter (group A) and 270 with a urethral stent plus a gastric tube (group B).

Objective: To explore the value of on-pump beating-heart coronary artery bypass grafting (OnP-BH CABG) for left-main patients with coronary heart disease through a comparative study with conventional coronary artery bypass grafting (CCABG).

Methods: The clinical data were retrospectively analyzed for 66 patients of OnP-BH and 48 control cases undergoing CCABG from January 2009 to January 2012 at Department of Cardiac Surgery, People's Hospital of Zhengzhou University.

Results: OnP-BH group had a better clinical outcome than CCABG group.

Objective: To assess recovery of renal parenchymal thickness and urinary protein levels in patients with severely hydronephrotic kidneys after nephrostomy placement.

Methods: Fourteen patients (median age 1 year, range 6 months-7 years) who underwent nephrostomy placement for unilateral ureteropelvic junction obstruction at our hospital between May 2007 and January 2009 were included in a retrospective analysis. All patients had severe hydronephrosis, with a median parenchymal thickness of 1.

Article Synopsis
  • The study aimed to evaluate the effects of a gene therapy using recombinant adeno-associated virus carrying the human endostatin gene on endometriosis in a mouse model.
  • The method involved creating endometriosis in nude mice by transplanting human endometrial tissue and then treating these mice with different viral vectors over three weeks to measure changes in ectopic lesions.
  • Results showed that the treatment led to a significant reduction in the number of glands in the ectopic lesions, indicating the therapeutic potential of endostatin gene therapy for endometriosis.

Several experiences with laparoscopic management of müllerian duct remnants (MDRs) have been reported to date. This report outlines our experience and reviews the present literature to evaluate the results of laparoscopic excision of MDR. Between April 2003 and December 2007, 4 male patients (age range, 6-20 years) with MDR underwent laparoscopic excision in our center.

Objective: To assess interleukin (IL)-1alpha, beta and interferon (IFN) gamma expression in macrophages in eutopic and ectopic endometrium of women with endometriosis.

Methods: In situ hybridization was used to examine the expression of IL-1alpha and beta and IFN-gamma in macrophages from eutopic and ectopic endometrium of 40 women with endometriosis and 15 control women. Eutopic endometrial samples were histologically classified into proliferative and secretary phases.

Effect of surfactant on the evaporative loss of benzene, toluene and ethylbenzene from static water was researched and the mechanism of surfactant was studied, so as try to supply theoretical reference for the effect of surfactant on the evaporation of complex pollution in water system. Sodium dodecylbenzene sulfonate (SDBS), cetyltrimethyl ammonium bromide (CTMAB) and polyoxyethylene(4) lauryl ether(Brij30) were used in the experiment. The results show when the surfactant concentrations exceeded their critical micelle concentrations (CMCs) and were set above 1 000mg/L, 2 000mg/L and 3 000mg/L respectively, the evaporative loss velocity of ethylbenzene, toluene and benzene began to decrease and their half-lives prolonged consequently.

The sorption behavior for organobentonites to sorb organic pollutants from metal-organic pollutant systems were investigated. The results suggested that in organobentonite/Pb2+/p-nitrophenol solute systems, Pb2+ can slow the sorption velocity of organobentonite to adsorb p-nitrophenol from water. Pb2+ and p-nitriphenol exhibit a competitive effect.
