Risk factors for tubal patency and their impact on pregnancy rate after partial salpingectomy and end-to-end anastomosis.

Objectives: To explore the risk factors for tubal patency after partial salpingectomy and end-to-end anastomosis, and their impact on pregnancy outcomes.

Methods: A total of 300 patients with tubal pregnancy who underwent partial salpingectomy and end-to-end anastomosis in Zhengzhou Maternal and Child Health Hospital from January 2020 to April 2023 were enrolled in the study. Hysterosalpingography was performed after surgical treatment to examine the tubal patency.

Uterine adenomatoid tumor: a clinicopathologic study of 102 cases.

Objective: Uterine adenomatoid tumors (UATs) are tubercle without significant clinical features. The study aims to summarize the clinicopathological characteristics of UATs to improve diagnostic accuracy.

Methods: Between January 2014 and December 2015, 4326 uterine specimens were collected from patients who received hysterectomy or myomectomy, of which 102 cases were pathologically confirmed as UATs.

Effectiveness of estrogen treatment before transcervical resection of adhesions on moderate and severe uterine adhesion patients.

Intrauterine adhesion (IUA), also known as Asherman's syndrome, is a common disease for among women. The extent of adhesion and pre-surgery hormone therapy greatly affects the function of uterine cavity. This current study investigates the association of different doses of estrogen before transcervical resection of adhesions (TCRA) surgery and clinical outcome in serious IUA.

Genetics and Epigenetics of Glioblastoma: Applications and Overall Incidence of IDH1 Mutation.

Glioblastoma is the most fatal brain cancer found in humans. Patients suffering from glioblastoma have a dismal prognosis, with a median survival of 15 months. The tumor may develop rapidly de novo in older patients or through progression from anaplastic astrocytomas in younger patients if glioblastoma is primary or secondary, respectively.

Review: Effect study of sex hormone in the multiple sclerosis of common neurological disorders.

Multiple sclerosis (MS) is one of most common neurological disorders, mainly affecting women. The central nervous system (CNS) of this autoimmune disease is characterized by intermittent or chronic damage to the myelin sheaths (demyelination), local inflammation and axonal degeneration. During the early relapsing/remitting stages of MS, myelin can regenerate.

[Primary application and evaluation of a technology for objective measurement of accommodation of human eyes].

Objective: To evaluate the practical value of a new technology for objective measurement of accommodation of human eyes.

Methods: It was a comparative study of some techniques for measuring the accommodation of human eyes. Twenty-six outpatients (20 male, 6 female, 10-37 years old) that were suspected to be abnormal in accommodation were examined with Nidek ARK-730 (with software AA-1 inside).

Study of hypoxia-induced expression of HIF-1alpha in retina pigment epithelium.

It was shown that the expression of HIF-1alpha in retinal pigment epithelium increased under hypoxic conditions. Eight hours after the start of hypoxic exposure, the expression of HIF-1alpha reached the peak and sustained after 24-hour hypoxia. However, the morphology of PRE cells began to change and the expression of HIF-1alpha decreased after long-term (48-hour) hypoxia.

Clinical analysis of endophthalmitis after phacoemulsification.

Background: Most cases of exogenous endophthalmitis occur after intraocular surgery. Although phacoemulsification is quick and convenient, there are some risks involved, and infection is one of them. This study investigated the associated factors and methods of prevention and treatment of endophthalmitis after phacoemulsification.

Biomechanical characteristics investigation on long-term free graft with expanded porcine skin.

Background: Free skin graft has to be used when the large area skin are burned. The objective of this study is to quantify the influence of free graft and expansion on the skin biomechanical remodeling.

Method: Four white pigs (weighing from 17 kg to 23 kg) were used.
