Objective To analyze the complications and clinical effects of interventional embolization and surgical clipping for the treatment of posterior communicating artery aneurysms, and to compare the results between the two methods.Methods A total of 90 patients with confirmed posterior communicating artery aneurysm, who were admitted to the Second Affiliated Hospital of Zhengzhou University during the period from August 2013 to March 2015, were enrolled in this study. Of the 90 patients, 49 received interventional embolization therapy (interventional embolization group) and 41 underwent surgical clipping treatment (surgical clipping group). Before the treatment the patient's condition was evaluated according to Hunt-Hess classification, after the treatment the therapeutic effect was assessed with Glasgow prognosis scale (GOS). The postoperative GOS scores and complications in patients with different Hunt-Hess classification were compared between the two groups. Results In patients of Hunt-Hess 0-Ⅲ grade, no statistically significant differences in postoperative GOS scores existed between the interventional embolization group and the surgical clipping group (t=0.842,P>0.05), while the postoperative GOS scores in patients of Hunt-HessⅣgrade of the interventional embolization group was remarkably higher than that in patients of Hunt-HessⅣgrade of the surgical clipping group, the difference was statistically significant (t=1.713,P<0.05). The incidence of complications in the interventional embolization group was significantly lower than that in the surgical clipping group (x2=1.036,P<0.05). Conclusion For the treatment of Hunt-Hess 0-Ⅲgrade posterior communicating artery aneurysms, the interventional embolization and the surgical clipping show no difference in their therapeutic effects; while for the treatment of Hunt-Hess Ⅳ grade posterior communicating artery aneurysms, the interventional embolization in superior to the surgical clipping, as the interventional embolization carries lower operation risk and complication incidence, and it also has reliable effect.

Objective To investigate the effect of early application of clean intermittent catheterization(CIC) in infants with neurogenic bladder(NB).Methods Eighty-seven children with NB diagnosed in our urodynamic center were less than 1 year old when they first came to hospital from January 2007 to January 2010, and CIC was carried out at different age.Sixty-four patients were followed up for a long time and divided into early CIC group(less than 1 year old children) and late CIC group(more than 3 years old children) according to the treatment time.Early CIC group included 29 patients [19 boys and 10 girls with the mean age of (7.5 ±2.8) months].And 4 cases were suffering from postoperative spina bifida manifesta;22 cases with spina bifida occulta;2 cases with sacral dysplasia;1 case with meningitis.Late CIC group included 35 patients [20 boys and 15 girls with the mean age of (8.0 ±2.9) months].2 cases were suffering from postoperative spina bifida manifesta;28 cases with spina bifida occulta;4 cases with sacral dysplasia;1 case with postoperative pelvic surgery.Before the treatment, there were no significant differences of the bladder compliance (BC), the maximum cystometric capacity (MCC) and the safety bladder capacity (SBC) between two groups.Urodynamic parameters and complications of 64 patients who were successfully followed up for 6 years were compared.Results After 3 years follow up, BC, SBC and MCC in early CIC group [(8.5 ± 1.9) ml/cmH2O, (140 ±25) ml, (142 ±29) ml]were significantly higher than those of late CIC group [(7.0 ± 2.2) ml/cmH2O, (110 ± 31) ml, (120 ± 28) ml;all P ＜ 0.05].After 6 years follow up, BC, SBC and MCC in early CIC group [(12.0 ±2.5) ml/cmH2O, (210 ±26) ml, (230 ±30) ml] were significantly higher than those of late CIC group [(9.3 ± 2.3) ml/cmH2O, (192 ± 31) ml, (205 ± 35) ml;all P ＜ 0.05], and the vesicoureteral reflux rate [24.1％ (7/29)] in early treatment group was significantly less than that in late treatment group [54.3％ (19/35), P ＜ 0.05].Increases in BUN and serum creatinine were found in 6 cases (20.7％) in early CIC group and 17 cases (48.6％) in late CIC group, the difference was significant (P ＜ 0.05).Conclusion For NB patients, the effect of early CIC is better than that of late CIC.

Objective To compare the effect of left transradial approach(TRA)with right TRA in performing transcatheter arterial chemoembolization(TACE)for the treatment of hepatocellular carcinoma(HCC).Methods The clinical data of a total of 174 HCC patients,who received conventional TACE via radial access at Henan Provincial Hospital of Traditional Chinese Medicine of China between June 2021 and May 2022,were retrospectively analyzed.Among the 174 patients,104 patients were ≤65 years old,of whom 52 received TACE by using left TRA and 54 received TACE by using right TRA;68 patients were＞65 years old,of whom 32 received TACE by using left TRA and 36 received TACE by using right TRA.The complications,fluoroscopy time spent for catheterization into celiac trunk,surgical total fluoroscopy time and radiation dose were compared between the left TRA group and right TRA group.Results In the patients ≤ 65 years old,there were no statistically significant differences in the fluoroscopy time spent for catheterization into celiac trunk,the surgical total fluoroscopy time,the radiation dose and the incidence of complications between the left TRA group and the right TRA group.In the patients＞65 years old,no statistically significant difference in the incidence of complications existed between the left TRA group and the right TRA group(P＞0.05),while the fluoroscopy time spent for catheterization into celiac trunk((60.3±28.3)s vs(86.3±45.2)s,P=0.003),the surgical total fluoroscopy time((11.2±4.5)min vs(14.3±6.3)min,P=0.030)and the radiation dose((452.2±121.7)mGy vs(563.8±181.5)mGy,P=0.022)in the left TRA group were remarkably lower than those in the right TRA group,the differences were statistically significant.Conclusion In conventional TACE,there is no obvious difference in the incidence of puncture point-related complications between using left TRA and using right TRA;but in the patients ≤ 65 years old,the use of left TRA can significantly reduce the surgical total fluoroscopy time and radiation dose.(J Intervent Radiol,2023,32:1226-1229)

Objective To study the mechanism of restenosis following percutaneous transluminal coronary angioplasty(PTCA),and to replicate a dynamic model of cell proliferation and remoulding of vascular wall at different time points in rabbits after intimal injury.Methods The model of restenosis in common carotid artery was established by balloon injury in 70 rabbits.The indexes such as lumen area,thickness and area of intima and media,and cross sectional area bounded by the external elastic lamina(EELA) were respectively measured by computer image analysis technology at the 1st,3rd,5th, 7th,14th,28th and 35th day after the injury.Results Endothelial cells were denudated at the 1st day after injury.The proliferation of vascular smooth muscle cell(VSMC) was detected on the surface of lumen at 3 days after injury.At the 7th day after injury,the neointima was formed and continuously thicken.The thickness and area of the neointima as well as extracellular matrix were gradually increased after 14 days,and were maximal after 35 days.The thickness and area of media were also gradually increased during 3～14 days and decreased after 28 days.Compared with non-injured vessel,the medial area was obviously increased at the 14th day.The lumen area was decreased at the 5th～7th day after injury and was obviously less than that of non~injured vessel after 14 days.The EELA was gradually increased at the 1st～7th day after injury,and reached its maximum at the 14th day.The EELA was declined gradually after 28 days.Conclusion The progress of restenosis(RS) can be simulated through the model of restenosis in common carotid artery of rabbit established by balloon injury.The intimal proliferation and vascular remodeling are the leading pathogenesis of restenosis.

Objective:To explore the relationship between proactive personality, resilience and achievement motivation of military cadets, and to explore the mediating role of resilience between proactive personality and achievement motivation, as well as the moderating effect of cadets’leading ability on this mediating role.Methods:In this study, 109 military cadets were measured with proactive personality scale, Connor-Davidson resilience scale (CD-RISC) and achievement motivation scale. SPSS 26.0 was used for descriptive statistical analysis and correlation analysis.Results:①There was a significant correlation among the total scores of proactive personality, resilience and achievement motivation ( Ps<0.01). ②Proactive personality could significantly predict the level of achievement motivation ( a=0.454, P<0.001), and resilience could significantly predict the level of achievement motivation ( b=0.231, P=0.019). ③Resilience significantly mediated the relationship between proactive personality and achievement motivation ( c′=0.3, P=0.003). ④Cadets' leading ability moderated the effect of resilience on achievement motivation (index=0.338, 95% CI: 0.057 to 0.881). The mediating effect of resilience between proactive personality and achievement motivation was significant for cadets' leaders (Effect=0.381, 95% CI: 0.085 to 1.005), but not significant for other students (Effect=0.043, 95% CI: -0.069 to 0.252). Conclusion:The proactive personality of military cadets can affect the level of achievement motivation through psychological resilience, which is also moderated by cadre identity, suggesting that military education should improve the level of achievement motivation in many ways.
