Background
Ocular motor dysfunction is one of the most common postoperative complications of petroclival meningioma. However, its incidence, recovery rate, and independent risk factors remain poorly ...explored.
Methods
A prospective analysis of 31 petroclival meningiomas was performed. Operative approaches were selected by utilizing a new 6-region classification of petroclival meningiomas we proposed. Two scores were used to evaluate the functions of the oculomotor and abducens nerves. Pearson correlation analysis and binary logistic regression analysis were used to identify independent risk factors for intraoperative oculomotor and abducens nerve injury.
Results
Postoperative new-onset dysfunctions in the pupillary light reflex and eye/eyelid movements as well as abducens paralysis were detected in eight (25.8%), ten (32.3%) and twelve (38.7%) cases, respectively. Their corresponding recovery rates after 6 months of follow-up were 75% (6/8), 80% (8/10), and 83.3% (10/12), respectively, and their mean times to start recovery were 4.03, 2.43, and 2.5 months, respectively. Tumor invasion into the suprasellar region/sphenoid sinus was the only risk factor for dysfunctions in both the pupillary light reflex (
p
= 0.001) and eye/eyelid movements (
p
= 0.002). Intraoperative utilization of the infratrigeminal interspace was the only risk factor for dysfunction in eyeball abduction movement (
p
= 0.004).
Conclusions
Dysfunctions of the oculomotor and abducens nerves recovered within 6 months postoperatively. Tumor extension into the suprasellar region/sphenoid sinus was the only risk factor for oculomotor nerve paralysis. Eye/eyelid movements were more sensitive than the pupillary light reflex in reflecting nerve dysfunctions. Intraoperative utilization of the infratrigeminal interspace was the only risk factor for abducens nerve paralysis.
The interactions between fluoroquinolones and human serum albumin (HSA) were investigated by affinity capillary electrophoresis (ACE) and fluorescence quenching technique. Based on the efficient ...separation of several fluoroquinolones using a simple phosphate buffer, the binding constants of fluoroquinolones with HSA were determined simultaneously during one set of electrophoresis by ACE method. The thermodynamic parameters were obtained from data at different temperatures, and the negative Δ
H and Δ
S values showed that both hydrogen bonds and van der Waals interaction played major roles in the binding of fluoroquinolones to HSA. The interactions were also studied by fluorescence quenching technique. The results of fluorescence titration revealed that fluoroquinolones had the strong ability to quenching the intrinsic fluorescence of HSA through the static quenching procedure. The binding site number
n, apparent binding constant
K
b and the Stern–Volmer quenching constant
K
sv were determined. The thermodynamic parameters were also studied by fluorescence method, and the results were consonant with that of ACE.
•Postoperative radiotherapy was significantly associated with longer progression-free survival and overall survival.•Gross-total resection was a favourable factor for progression-free survival and ...overall survival.•Homogeneous contrast on magnetic resonance imaging may be a better prognostic factor for progression-free survival.
Anaplastic meningiomas (AMs)tend to have a higher local recurrence rate and metastasize. but few studies have reported on the prognosis and management of patients with AM, this study aimed to increase the understanding of the prognosis, management and history of AM.
All patients (n = 56) underwent surgeries in our hospital between December 2008 and January 2016. Postoperative pathology reports confirmed the diagnosis of AM. Prognostic factors and the management were analysed in this study. AM was then divided into two groups. One group was primary AM, the other group was secondary AM.
Of all the 56 AM patients, 31 were male and 25 were female (male to female ratio of 1.24:1). The 1-, 3-, and 5-year progression-free survival (PFS) rates were 78.6%, 41.1% and 29.7%, respectively, and the corresponding overall survival (OS) rates were 82.1%, 50.1% and 45.0%, respectively. Homogeneous contrast might be a potential better prognostic factor for PFS (HR = 1.824, P = 0.083). Treatment with postoperative radiotherapy (PRT) was significantly associated with longer PFS (HR = 0.390, P = 0.007) and OS (HR = 0.376, P = 0.008) according to univariate analysis. Gross-total resection (GTR) was a favourable factor for PFS (HR = 2.059, P = 0.035) and OS (HR = 2.802, P = 0.004).
Achieving GTR is a favourable treatment strategy for patients with AM in our study and patients receiving PRT after resection is essential.
Forsythiae Fructus (FF), the fruit of
Forsythia suspensa
(Thunb.) Vahl. (Lianqiao), is one of the most fundamental herbs in Traditional Chinese Medicines (TCM), mainly due to its heat-clearing and ...detoxifying effects. There are two types of FF, the greenish fruits that start to ripen (GF) and the yellow fruits that are fully ripe (RF), called “Qingqiao” and “Laoqiao” referred to the Chinese Pharmacopoeia, respectively. It undergoes a complex series of changes during the maturation of FF. However, the clinical uses and preparation of phytopharmaceuticals of FF have not been distinguished to date. Moreover, there is limited information on the study of the difference in pharmacological activity between RF and GF. In this study, a rat model of bile duct ligation (BDL)-induced cholestasis was used to compare the differences in their effects. RF was found to have better results than GF in addressing toxic bile acids (BAs) accumulation and related pathological conditions caused by BDL. The underlying mechanism may be related to the interventions of gut microbiota. The results of the present study suggest that the better detoxifying effect of RF than GF may be indirectly exerted through the regulation of gut microbiota and thus the improvement of BAs metabolism.
AIM:To investigate the role of pre-B-cell leukemia homeobox(PBX)3 in migration and invasion of colorectal cancer(CRC)cells.METHODS:We detected PBX3 expression in five cell lines and surgical ...specimens from 111 patients with CRC using real-time reverse transcription-polymerase chain reaction.We forced expression of PBX3 in low metastatic HT-29 and SW480 cells and knocked down expression of PBX3 in highly metastatic LOVO and HCT-8 cells.Wound healing and Boyden chamber assays were used to detect cell migration and invasionafter altered expression of PBX3.Western blot was performed to detect the change of signaling molecule ERK1/2 following PBX3 overexpression.RESULTS:High level of PBX3 expression was correlated with the invasive potential of CRC cells,and significantly associated with lymph node invasion(P=0.02),distant metastasis(P=0.04),advanced TNM stage(P=0.03)and poor overall survival of patients(P<0.05).Ectopic expression of PBX3 in low metastatic cells was shown to promote migration and invasion,while inhibited PBX3 expression in highly metastatic cells suppressed migration and invasion.Furthermore,upregulation of phosphorylated extracellular signal-regulated kinase(ERK)1/2 was found to be one of the targeted molecules responsible for PBX3-induced CRC cell migration and invasion.CONCLUSION:PBX3 induces invasion and metastasis of CRC cells partially through activation of the MAPK/ERK signaling pathway.
Background: Several studies were published to assess the association between serum uric acid levels and atrial fibrillation risk, but no consistent results were reported. We performed a meta-analysis ...to evaluate the evidence of the association between hyperuricemia and atrial fibrillation risk. Material/Methods: Pubmed and Embase databases were searched for prospective cohort studies assessing the association between hyperuricemia and atrial fibrillation risk. Relative risks (RRs) with corresponding 95% confidence intervals (95%CIs) were pooled using random-effect of meta-analysis to assess the risk of atrial fibrillation in individuals with hyperuricemia. Results: Six cohort studies were finally included into the meta-analysis. Meta-analysis of those 6 studies showed that hyperuricemia was significantly associated with increased risk of atrial fibrillation (RR = 1.49, 95%CI 1.24-1.79, P < 0.001). Sensitivity analysis by omitting single study sequentially by turns did not have any obvious influence on the pooled risk estimates. There was no obvious risk of publication bias in the meta-analysis. Conclusions: Based on the currently available data, hyperuricemia is associated with increased risk of atrial fibrillation.
The tripartite motif (TRIM) family proteins exhibit oncogenic or anti-oncogenic roles in various cancers. As a TRIM family member, TRIM36 is expressed in lung adenocarcinoma (LUAD), but its roles ...remain unexplored. Here, we set to investigate the clinical relevance and the biological actions of TRIM36 in LUAD. mRNA levels of TRIM36 and the Kaplan-Meier survival analysis for patients with LUAD were analyzed from The Cancer Genome Atlas (TCGA) database. Real-time PCR and western blotting were utilized to measure TRIM36 levels both in vivo and in vitro. We demonstrated that TRIM36 levels were significantly decreased in LUAD patients. The low expression of TRIM36 was correlated with a poor prognosis. Overexpression and knock-down studies illustrated that TRIM36 inhibits cell proliferation and promotes apoptosis in LUAD cell lines. LUAD cells were irradiated with 60Co. In addition, TRIM36 enhanced radiosensitivity in LUAD cell lines. Moreover, we found that TRIM36 expression was negatively associated with RAD51. Co-overexpressing RAD51 blocked TRIM36's effects on proliferation and apoptosis. TRIM36 formed a complex with RAD51, promoting its ubiquitination. Inhibiting hsa-miR-376a-5p enhanced apoptosis and the effects were mediated by TRIM36 in response to radiation. In conclusion, our results indicated that TRIM36 is anti-oncogenic in LUAD by promoting RAD1 ubiquitination. Hsa-miR-376a-5p acts upstream of TRIM36. TRIM36 and RAD1 may serve as prognostic indicators for LUAD. The interactions between TRIM36, RAD1 and hsa-miR-376a-5p can be future therapeutic targets to increase radiation sensitivity in LUAD patients.
•Downregulation of TRIM36 contributed to the poor prognosis of LUAD.•TRIM36 inhibited proliferation and promoted apoptosis in LUAD cells.•TRIM36 was negatively related to DNA repair in LUAD cells.•TRIM36 increased radiation-sensitivity by promoting RAD51 ubiquitination.•miR-376a-5p acted as an upstream regulator of TRIM36.
The estimated glomerular filtration rate (eGFR) based on creatinine is crucial for the risk assessment of contrast-associated acute kidney injury (CA-AKI). In recent, the difference between cystatin ...C-based eGFR (eGFRcys) and creatinine-based eGFR (eGFRcr) has been widely documented. We aimed to explore whether intraindividual differences between eGFRcys and eGFRcr had potential value for CA-AKI risk assessment in patients undergoing elective percutaneous coronary intervention (PCI).
From January 2012 to December 2018, we retrospectively observed 5049 patients receiving elective PCI. To determine eGFR, serum creatinine and cystatin C levels were measured. CA-AKI was defined as serum creatinine being increased ≥ 50% or 0.3 mg/dL within 48 h after contrast agents exposure. Chronic kidney disease (CKD) was defined as the eGFR < 60 mL/min/1.73 m
.
Approximately half of the participants (2479, 49.1%) had a baseline eGFRdiff (eGFRcys-eGFRcr) between -15 and 15 mL/min/1.73 m
. Restricted cubic splines analysis revealed a nonlinear relationship between eGFRdiff and CA-AKI. Multivariable logistic regression analysis indicated that compared with the reference group (-15 to 15 mL/min/1.73 m
), the negative-eGFRdiff group (less than -15 mL/min/1.73 m
) had a higher risk of CA-AKI (OR, 3.44; 95% CI, 2.57-4.64). Furthermore, patients were divided into four groups based on CKD identified by eGFRcys or eGFRcr. Multivariable logistic analysis revealed that patients with either CKDcys (OR, 2.94; 95% CI, 2.19-3.95,
< 0.001) or CKDcr (OR, 2.44; 95% CI, 1.19-4.63,
< 0.001) had an elevated risk of CA-AKI compared to those without CKDcys and CKDcr.
There are frequent intraindividual differences between eGFRcys and eGFRcr, and these differences can be used to forecast the risk of CA-AKI.
BackgroundHaemorrhages of brainstem cavernous malformations (CMs) can lead to neurological deficits, the natural history of which is uncertain. The study aimed to evaluate the neurological outcomes ...of untreated brainstem CMs and to identify the adverse factors associated with worsened outcomes.MethodsFrom 2009 to 2015, 698 patients (321 women) with brainstem CMs were entered into the prospective cohort after excluding patients lost to follow-up (n=43). All patients were registered, clinical data were collected and scheduled follow-up was performed.ResultsAfter a median follow-up of 60.9 months, prospective haemorrhages occurred in 167 patients (23.9%). The mean modified Rankin Scale scores at enrolment and at censoring time were 1.6 and 1.2. Neurological status was improved, unchanged and worsened in 334 (47.9%), 293 (42.0%) and 71 (10.2%) patients, respectively; 233 (33.4%) recovered to normal levels. Lesions crossing the axial midpoint (relative risk (RR) 2.325, p=0.003) and developmental venous anomaly (DVA) (RR 1.776, p=0.036) were independently significantly related to worsened outcomes. The percentage of worsened outcomes was 5.3% (18 of 337) in low-risk patients (neither DVA nor crossing the axial point) and increased to 26.0% (13 of 50) in high-risk patients (with both DVA and crossing the axial point). The percentage of worsened outcomes significantly increased as the number of prospective haemorrhages increased (from 1.5% (8 of 531, if 0 prospective ictus) to 37.5% (48 of 128, if 1 ictus) and 38.5% (15 of 39, if >1 ictus)).ConclusionsThe neurological outcomes of untreated brainstem CMs were improved/unchanged in majority of patients (89.8%) with a fatality rate of 1.7% in our cohort, which seemed to be favourable. Radiological features significantly predicted worsened outcomes. Our results provide evidence for clinical consultation and individualised treatment. The referral bias of our cohort was underlined.
The stochastic generalized equation provides a unifying methodology to study several important stochastic programming problems in engineering and economics. Under some metric regularity conditions, ...the quantitative stability analysis of solutions of a stochastic generalized equation with the variation of the probability measure is investigated via Brouwer’s fixed point theorem. In particular, the error bounds described by Hausdorff distance between the solution sets are established against the variation of the probability measure. The stability results obtained are finally applied to a stochastic conic programming.
