ABSTRACT
Objective:To investigate the safety and effectiveness of Solitaire FR with intracranial support catheter for mechanical thrombectomy (SWIM) in the treatment of cerebral venous sinus thrombosis (CVST).Methods:Patients with progressive CVST treated with SWIM technology in the Neurology Department, Zhongshan Hospital of Chinese Medicine Affiliated to Guangzhou University of Chinese Medicine from June 2019 to March 2022 (including 4 patients with intracranial hemorrhage) were retrospectively included. The venous sinus recanalization after procedure and during follow-up was observed. The modified Rankin Scale (mRS) was used to evaluate the outcome at 3 months after procedure.Results:A total of 9 patients with progressive CVST were treated with SWIM technology, including 6 males with a median age of 37.0 years (range, 15-78). Immediately post-procedural angiography showed complete recanalization of the venous sinuses in 6 cases and partial recanalization in 3 cases. At 3 months after procedure, the mRS score showed that 3 cases was 0, 3 cases was 1, 2 cases was 2, and 1 case was 4.Conclusion:SWIM technology may be a safe and effective method in the treatment of progressive CVST.
ABSTRACT
Objective:To investigate the risk factors for futile recanalization in patients with acute anterior circulation large vessel occlusion after endovascular mechanical thrombectomy (EMT), and establish a nomogram model predicting futile recanalization in these patients.Methods:One hundred and eighty-eight patients with acute anterior circulation large vessel occlusion after EMT were enrolled from Department of Neurology, Zhongshan Hospital of Chinese Medicine, Guangzhou University of Chinese Medicine from January 2018 to December 2021. Patients were divided into futile recanalization group and effective recanalization group according to whether futile recanalization occurred; futile recanalization was defined as successful recanalization showed by immediate postoperative DSA (modified thrombolysis in cerebral infarction [mTICI] ≥2b), but poor functional outcome (modified Rankin Scale [mRS] scores>2 90 d after surgery). The clinical data were compared between futile recanalization group and effective recanalization group. Multivariate Logistic regression analysis was used to screen the risk factors for futile recanalization. R software was used to establish a nomogram model for futile recanalization. C-index was used to evaluate the differentiation of the model, and correction curve was used to evaluate the accuracy of the line graph model prediction. Receiver operating characteristic (ROC) curve was used to evaluate the predictive efficiency of the nomogram model.Results:Ninety-two patients had futile recanalization. Compared with the effective recanalization group, futile recanalization group had significantly older age, significantly higher hemoglobin A1c on admission, significantly longer time from puncture to vascular recanalization, significantly higher proportions of patients with hypertension history and poor collateral circulation, and significantly different severities of stroke and white matter hyperintensities (WMHs) and distribution of occlusive sites ( P<0.05). Multivariate Logistic regression analysis showed that age, history of hypertension, time from puncture to vascular recanalization, poor collateral circulation, severe WMHs, and moderate-severe stroke were independent risk factors for futile recanalization after EMT in patients with acute anterior circulation large vessel occlusion ( P<0.05). A nomogram model of futile recanalization was established according to the above 6 factors, with C-index of 0.862 ( 95%CI: 0.809-0.914); the calibration curve of the model was highly coordinated to the ideal model curve; area under the ROC curve of futile recanalization was 0.862 ( 95%CI: 0.809-0.914, P<0.001). Conclusions:Acute anterior circulation large vessel occlusion patients with older age, history of hypertension, longer time from puncture to vascular recanalization, poor collateral circulation, severe WMHs, and moderate-severe stroke trend to have futile recanalization after EMT. This nomogram can predict futile recanalization after EMT.
ABSTRACT
ObjectiveTo investigate the correlation and expression of fragile histidinetriad gene(FHIT) and p53 expressed in normal cervix,cervical intraepithelial neoplasia( CIN),cervial cancer( CC),and the significance of FHIT and p53 in the chnical diagnosis,treatment and prognosis of cervical cancer.MethodsIt was performed immunohistochemieal analysis of formalin fixed,paraffin-embedded 20 normal cervical(NC) biopsies,10 CIN1 samples、20CIN Ⅱ samples、20 CINⅢ samples and 70 cervical cancer samples to detect FHIT、p53expression.ResultsFHIT expressed 100％ (20/20) of normal cervical,60％ (6/10) of CIN Ⅰ,40％ (8/20) of CIN Ⅱ,25％ (5/20) of CINⅢ and 3％ (2/70) of cervical cancer;positive rate among the groups was different (P ＜ 0.05 ).p53 positive expressed in 0％ (0/20) of normal cervical,20％ (2/20) of CIN Ⅰ,35 ％ ( 7/20 ) of CIN Ⅱ,55％ ( 11/20 ) of CIN Ⅲ and 70％(49/70) of cervical cancer:positive rate among the groups was different (P ＜ 0.05 ).FHIT and p53 expression was negatively correlated with CIN and cervical cancer in the cervix ( P ＜ 0.05 ).ConclusionFHIT deletion and p53 overexpression was the early and common cases with the cervical cancer,which were negatively correlated in the pathogensis and development of cervical cancer:FHIT could screen the high risk of CIN,and give the basis of cervical cancer gene therepy.
ABSTRACT
Objective To explore the ovarian tumor's characteristics, diagnosis and treatment during pregnancy.Methods A retrospective analysis of 156 cases of ovarian tumor was carried out.Results About 152 cases were dignosed as benign,accounting for 97.44%.The majority of which were demoid cysts and grout cystadenomas,two cases were bordline grout papillary cystaadenoma,other 2 cases,one was some of immature teratoma, another was immature teratoma.67 cases were diagnosed by ultrasound during the first trimester, accountting for 80.72%, among 17 urgent operations,10 cases caused by torsion,7 cases caused by rupture.43 cases operated by term,among which 39 cases were tradion operations,4 cases were laparoscopic surgery.18 cases made the examination of CA125 before operation,as a result,13 cases elevated,AFP examination were made in 10 cases,7 cases elevated.Full-term birth was in 152 patients, accounting for 97.44%.Conclusion Majority ovarian tumor during prenaney were benign;Ultrasound examination combined with tumor marker were important in diagnosis and detection ovarian tumor during pregnancy; The individual operation therapy should be chosen, according to the tumor's properties, gestational weeks, and patients' will;Timely open surgery or laparoscopic surgery should not affect the pregnancy outcome.
ABSTRACT
ObjectiveTo explore the clinical characteristics of pregnancy and delivery in older pregnant women. MethodsRetrospectively analyzed the clinical deta of old group ( age ＞ = 35, n = 636) and non-old group ( age ＜ 35, n = 4 202) in same time, compared the incidence of pregnant complications and delivery complications, situation of perinatal infants between the two groups. ResultsThe incidence rates of gestational diabetes,hypertension disease, placenta previa, cesarean section, postpartum hemorrhage, fetal macrosomia were higher in old group and neonatal deformity,neonatal asphyxia were not different in two groups. CondusionThe complications during pregnancy and delivery increased in older pregnant women,which had no benifits for mother son.
