Objective:To investigate the computed tomography (CT) imaging features of patients with chronic hydrocephalus after intracerebral hemorrhage surgery and the difference between endoscopic third ventriculostomy (ETV) and ventricular peritoneal shunt (VPS).Methods:A total of 158 patients with intracerebral hemorrhage who received surgical treatment in the Department of Neurosurgery of the People′s Hospital of Jinan from January 2021 to June 2023 were retrospectively selected as the study objects, including 78 patients with chronic hydrocephalus after surgery as the hydrocephalus group, and 80 patients with no hydrocephalus after surgery as the non-hydrocephalus group, and the CT imaging data of the patients were statistically analyzed. Hydrocephalus group was divided into ETV group (42 cases) and VPS group (36 cases) according to different treatment methods. The efficacy and quality of life of the two groups were compared, and the incidence of complications in the two groups were counted.Results:There was no significant difference between hydrocephalus group and non-hydrocephalus group in the site of cerebral hemorrhage, hematoma morphology and the proportion of patients with mixed signs, lobular signs and black hole signs (all P>0.05). The proportion of patients with ventricular dilation and hematoma enlargement in hydrocephalus group was significantly higher than that in non-hydrocephalus group (all P<0.05). The National Institute of Health Stroke Scale (NIHSS) scores of hydrocephalus patients in the two groups were measured continuously at different time points, and there was no significant difference in NIHSS scores between the ETV group and the VPS group before treatment, at 2 weeks and 4 weeks of treatment (all P>0.05). There was no significant difference between the ETV group and the VPS group ( P>0.05). The recurrence rate of the ETV group was lower than that of the VPS group ( P<0.05). The quality of life scores of patients in ETV group were higher than those in the VPS group at 3 months and 6 months after surgery ( P<0.05). Conclusions:CT examination of patients with chronic hydrocephalus after intracerebral hemorrhage will show obvious characteristics of hematoma enlargement and ventricle enlargement. The efficacy of ETV and VPS in the treatment of chronic hydrocephalus after intracerebral hemorrhage surgery is similar, but the former has a lower recurrence rate and a higher postoperative quality of life.

Objective This study aims to explore the impacts of short-term insemination and early rescue intracytoplasmic sperm injection (E-RICSI) on clinical and neonatal outcomes for IVF patients. Methods A retrospective analysis was conducted on the clinical data from the patients who underwent fresh embryo transfer at the Reproductive Center from January 2019 to December 2023. Patients were divided into four groups based on fertilization method:short-term IVF group (n=204),conventional IVF group (n=208),E-RICSI group (n=13) and conventional ICSI group (n=92). The fertilization rates,embryo development,pregnancy outcomes,and neonatal outcomes were compared between the short-term IVF and conventional IVF groups,and between the E-RICSI and conventional ICSI groups. Results There were no statistically significant differences in embryo development,clinical pregnancy,miscarriage,ectopic pregnancy,live birth rates,neonatal sex,and birth weight between the short-term IVF group and conventional IVF group. Similarly,no significant differences were observed in the E-RICSI group compared to the conventional ICSI group (P>0.05). However,the fertilization rate (79.11% vs. 84.39%,P<0.001) and the rate of 2PN zygotes (63.98% vs. 70.83%,P<0.001) were significantly lower in the short-term IVF group compared to the conventional IVF group;The fertilization rate (65.49% vs. 91.68%,P<0.001) and the rate of 2PN zygotes (57.75% vs. 88.35%,P<0.001) were significantly lower in the E-RICSI group compared to the conventional ICSI group. Conclusions Although the fertilization rate of short-term insemination and E-RICSI is lower than that of conventional IVF and ICSI,it has no effect on embryonic development,preg-nancy outcome and neonatal outcome. Short-term insemination combined with early rescue ICSI is an effective and safe technology to prevent complete fertilization failure.
