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:To explore the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in ruptured anterior communicating wide-necked aneurysms.Methods:Thirty-two patients with ruptured anterior communicating wide-necked aneurysms accepted Neuroform Atlas stent assisted coil embolization in Department of Neurosurgery, People's Hospital Affiliated to Shandong First Medical University from January 2022 to June 2023 were chosen. DSA was performed immediately after surgery, and aneurysm embolization was assessed using Raymond grading. Prognoses were assessed by modified Rankin Scale (mRS, mRS scores≤2 as good prognosis and mRS scores>2 as poor prognosis) at last follow-up. DSA was performed again 6 months after surgery to assess the aneurysm healingResults:Neuroform Atlas stents were successfully implanted in all 32 patients; Postoperative DSA showed that aneurysm embolization reached Raymond grading I in all 32 patients(100%). No such complications as in-stent thrombosis, cerebral vasospasm, or poor opening of the stent were noted excepted for one with intraoperative aneurysm rupture hemorrhage. At the last follow-up, 31 patients had good prognosis and 1 had poor prognosis; in 22 patients underwent DSA re-examination, Raymond grading I was noted in 20 patients (90.91%) and grading II in 2 (9.09%).Conclusion:Neuroform Atlas stent-assisted coil embolization for ruptured anterior communicating wide-necked aneurysms seems safe and effective.

Objective:To investigate the effects of bracket-free invisible orthodontic technique versus traditional fixed orthodontic technique on the levels of inflammatory factors in the gingival crevicular fluid of orthodontic adolescents. Methods:A total of 67 orthodontic patients who received their first orthodontic treatment in Huzhou Central Hospital from June to September 2020 were included in this study. They were randomly divided into an observation group ( n = 34) and a control group ( n = 33). The control group was treated with traditional fixed orthodontic treatment. The observation group was treated with invisible orthodontic treatment without brackets. At 0, 1, 2, 4, and 6 months of treatment, the level of inflammatory factors and periodontal index were compared. Results:At 0 and 1 month of treatment, there were no significant differences in the levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in the gingival crevicular fluid between the observation and control groups (all P > 0.05). At 2, 4, and 6 months of treatment, the levels of IL-1β, IL-6, and TNF-α in the observation group were significantly lower than those in the control group (IL-1β: t2 months = 5.56, P = 0.042; t4 months = 8.14, P = 0.019; t6 months = 9.87, P = 0.002. IL-6: t2 months = 7.15, P = 0.029; t4 months = 7.94, P = 0.021; t6 months = 9.16, P = 0.007. TNF-α: t2 months = 6.87, P = 0.039; t4 months = 7.65, P = 0.026: t6 months = 9.89, P = 0.001). In each group, gingival index (GI), sulcus bleeding index (SBI), probing depth (PD), and plaque index (PLI) increased significantly after treatment. At 0 and 1 month of treatment, there were no significant differences in GI, SBI, PD, and PLI between the two groups (all P > 0.05). At 2, 4, and 6 months of treatment, GI, SBI, PD, and PLI in the observation group were significantly lower than those in the control group (GI: t2 months = 3.62, P = 0.073; t4 months = 8.16, P = 0.018; t6 months = 8.54, P = 0.016. SBI: t2 months = 5.65, P = 0.042; t4 months = 7.56, P = 0.027; t6 months = 8.15, P = 0.019. PD: t2 months = 5.652, P = 0.042; t4 months = 7.56, P = 0.027, t6 months = 8.15, P = 0.019. PLI: t2 months = 9.57, P = 0.006; t4 months = 9.98, P = 0.002. t6 months = 9.94, P = 0.010). In addition, at 1 month of treatment, PLI in the observation group was significantly lower than that in the control group ( t = 9.99, P = 0.001). Conclusion:Bracket-free invisible orthodontic treatment provides better protection on periodontal tissue and has less impact on periodontal health than traditional fixed orthodontic treatment.

Objective:To investigate the current situation of medication near-miss reporting barriers for pediatric nurses for pediatric nurses and analyze its influencing factors.Methods:Using a multi-stage cluster sampling method, clinical pediatric nurses from 13 hospitals of Henan Province were selected as research objects from July to October 2020. General situation questionnaire, Hospital Safety Atmosphere Questionnaire, Medication Near-miss Reporting Barriers Scale, Multiple Leadership Style of Head Nurse Scale and Patient Safety Competency Nursing Staff Self-rating Scale were used for investigation, and related factors affecting medication near-miss reporting barriers for pediatric nurses were analyzed. A total of 1 104 questionnaires were distributed and 1 070 were effectively returned, with the effective recovery rate of 96.92%.Results:The reporting rate of 1 070 pediatric nurses who actively reported medication near-miss reporting barriers was 14.42%, and the score of Medication Near-miss Reporting Barriers Scale was (98.1±21.46) . The total scores of Hospital Safety Atmosphere Questionnaire was (77.36±12.97) , score of Multiple Leadership Style of Head Nurse Scale was (74.4±15.89) , and score of Patient Safety Competency Nursing Staff Self-rating Scale was (107.81±2.59) . The results of multiple linear regression analysis showed that educational background, entry length, job title, marital status, leadership style, patient safety competence, and hospital safety atmosphere were the main influencing factors of medication near-miss reporting barriers for pediatric nurses ( P<0.05) . Conclusions:The medication near-miss reporting barriers for pediatric nurses are common, which are influenced by educational background, years of employment, leadership style, hospital safety atmosphere and other factors. Nursing managers should strengthen pediatric nurses' awareness of medication near-miss reporting, implement transformational leadership style and improve patient safety competence and hospital safety atmosphere, so as to promote drug use safety of children.
