Objective To compare the clinical outcome of internal fixation(IF)and total hip arthroplasty (THA)for the elderly patients with displaced femoral neck fracture. Methods A total of 128 patients with dis-placed femoral neck fracture admitted from January 2010 to December 2012 were selected and divided into IF group(61 cases)and THA group(67 cases). The operation and hospitalization index were compared between the 2 groups. All patients underwent follow-ups after operation. The functional recovery scale for hip fracture (FRS) and EQ-5D index were applied to evaluate the clinical outcomes periodically. Results Compared to THA group, the intraoperative trauma ,operation time and bed days were less in IF group(P<0.05),however the incidence of complication in IF group was higher than that in THA group. All the patients were followed up more than 3 years and mortality rate between the 2 groups showed no significant difference(P>0.05). Follow-ups at all time points revealed hip function in THE group is better than that in IF group(P<0.05),while no significant difference was found in terms of life quality(P > 0.05). Within 3 years,the costs related to fracture were 41772 yuan for IF group and 61174 yuan for THA group respectively. Conclusion Both internal fixation and total hip arthroplasty can provide satisfactory outcome for elderly patients with displaced femoral neck fracture. Compared with IF ,THA causes bigger trauma and costs more ,but ends up with lower complication incidences ,and improve hip function in a shorter period.

Objective:To compare the efficacy and side effects between simultaneous and sequential integrated boost intensity-modulated radiotherapy after operation for high-grade glioma.Methods:We retrospectively analyzed 142 patients with high-grade glioma who underwent postoperative radiotherapy from January 2010 to December 2017. All patients were divided into the simultaneous and sequential integrated boost intensity-modulated radiotherapy groups. Concurrent temozolomide chemotherapy was delivered during radiotherapy in two groups. The follow-up outcomes were statistically compared between two groups.Results:For the whole group, the median overall survival (OS) was 24 months, the median progression-free survival (PFS) was 17 months, and the median disease-free survival (DFS) was 25 months. In the simultaneous and sequential integrated boost intensity-modulated radiotherapy groups, the median OS were 27.2 and 21.0 months ( P=0.950), the median PFS were 21.2 and 15.0 months ( P=0.21), and the median DFS were 28.0 and 18.0 months ( P=0.171), and the disease control rates were 92.86% and 85.17%( P=0.541), respectively. There was no statistical difference in OS, PFS, DFS, short-term efficacy and side effects between two groups. However, the conformity index in the simultaneous integrated boost intensity-modulated radiotherapy group was better than that in the sequential integrated boost intensity-modulated radiotherapy group ( P=0.032). Conclusions:Postoperative simultaneous and sequential integrated boost intensity-modulated radiotherapy yield no statistical differences in the survival, short-term efficacy and side effects in the treatment of high-grade glioma. However, the conformity index in the simultaneous integrated boost intensity-modulated radiotherapy group is significantly better, which can be recommended for postoperative radiotherapy of high-grade glioma.

Objective:To investigate the expression of CDK6 and FOXM1 in peripheral T-cell lymphoma (PTCL), and its correlation with clinicopathologic features and patient prognosis.Methods:The Oncomine was used for data mining and analyzing the expression levels of CDK6 and FOXM1 in PTCL. Immunohistochemistry (IHC) of EnVision method was used to detect the expression of CDK6 and FOXM1 proteins in 166 cases of PTCL diagnosed at Shanxi Provincial Cancer Hospital from January 2016 to December 2018, and 30 cases of lymph node with reactive hyperplasia as control.Results:Among the PTCL patients, 104 were male and 62 were female, aged from 3 to 85 years, with an average age of 53 years. Analyses of the Oncomine 4.5 database showed that mRNA expression of CDK6 and FOXM1 in PTCL tissues was significantly higher than that in normal tissue ( P<0.05). IHC staining showed the positive rates of CDK6 and FOXM1 proteins in PTCL tissues were 27.7% (46/166) and 80.7% (134/166), respectively. The expression was mainly present in the nuclei of tumor cells, showing a diffuse, strongly positive pattern. The positive rates of CDK6 and FOXM1 proteins among the 30 cases of lymph-node reactive hyperplasia were 0 (0/30) and 30% (9/30), respectively. The expression of FOXM1 was mainly found in the lymphoid follicle germinal center, and not present in the T-zone cells. CDK6 protein, FOXM1 protein and the co-expression of CDK6 and FOXM1 proteins in PTCL were associated with higher Ann Arbor staging and international prognostication index score ( P<0.05), and inversely associated with overall survival ( P<0.05). Meanwhile, CDK6 protein expression was positively correlated with FOXM1 protein expression ( P<0.05). Conclusions:CDK6 and FOXM1 may be new targets for the diagnosis and treatment of PTCL. The overexpression of CDK6 may lead to enhanced function of the transcription factor FOXM1, while the overexpression of CDK6 and FOXM1 also promotes the development and progression of PTCL.

Objective:To evaluate the safety and efficacy of intravenous tirofiban in stent-assisted embolization of acute ruptured intracranial aneurysms.Methods:A total of 286 patients with acute ruptured intracranial aneurysms who received stent-assisted embolization in Department of Neurosurgery, Linyi People's Hospital from January 2020 to September 2022 were enrolled. According to different preoperative antiplatelet regiments, they were divided into aspirin combined with double resistant group (preoperatively taking orally loading dose of aspirin and clopidogrel, n=167) and tirofiban group (intravenously injecting tirofiban, n=119). Propensity score matching (PSM) was used to adjust for potential differences in age, gender, Hunt-Hess grading, hypertension history, diabetes history, smoking history, aneurysm location, aneurysm neck, aneurysm body-neck ratio, and stent types; incidences of perioperative hemorrhagic and ischemic complications, and neurological recovery status at discharge (scores of modified Rankin scale [mRS]≤2 as good recovery) were compared between the two groups. Results:After 1:1 PSM, 96 patients were included in each group. No significant difference in incidence of hemorrhagic complications was noted between the double resistant group (2.1%) and tirofiban group (0.0%, P>0.05). No significant difference in incidence of ischemic complications was noted between the double resistant group (9.3%, including 8 with intraoperative thrombosis and 1 with postoperative infarction) and tirofiban group (7.2%, including 6 with intraoperative thrombosis and 1 with postoperative infarction, P>0.05). No significant difference in good recovery rate at discharge was noted between double resistant group (86.4%) and tirofiban group (90.6%, P>0.05). Conclusion:In stent-assisted embolization therapy for acute ruptured intracranial aneurysms, preoperative intravenous tirofiban enjoys the same safety and efficacy compared with preoperative oral loading dose of aspirin and clopidogrel.

In recent years, with the improvement of people's awareness of physical examination and the more accurate detection equipment, the detection rate of pulmonary nodules is getting higher and higher. Surgical resection is the first choice for the treatment of malignant pulmonary nodules, but multiple pulmonary nodules, nodules in complex areas and those with surgical contraindications are not suitable for surgery. As an effective, less invasive and low-cost treatment, ablation has developed rapidly in the treatment of multiple pulmonary nodules. This article introduces the progress of several common ablation techniques (radiofrequency ablation, microwave ablation, cryoablation) in the treatment of multiple pulmonary nodules, the indications and contraindications of ablation techniques, the efficacy evaluation and complications after ablation therapy, and the prospects of ablation techniques in the treatment of multiple pulmonary nodules.
