股骨头坏死区三维数字化模型建立及体积估算

BACKGROUND: Core decompression and autogenous bone grafts are widely used in treatment of early avascular necrosis of femoral head. According to the report, the success rate of this therapy has obvious difference; the reasons may be related to inaccurate puncture location and secondary damnification of repeated puncture.      

No association between polymorphisms in the calcium homeostasis modulator 1 gene and mesial temporal lobe epilepsy risk in a Chinese population

PurposeMesial temporal lobe epilepsy (MTLE) is one of the most common forms of epilepsies in adults. The calcium homeostasis modulator 1 gene (CALHM1) has been considered one of the candidate genes that play a role in epileptogenesis due to its function in calcium homeostasis and amyloid β (Aβ) regulation. Recently, the association of a single nucleotide polymorphism (rs11191692) of CALHM1 has been reported to be associated with MTLE in Han Chinese, but independent replication is needed. In the present study, rs11191692 and rs2986017 of CALHM1 were determined in 512 MTLE patients and 412 control subjects to investigate the possible involvement of CALHM1 in the etiology of MTLE.MethodGenotyping was determined by polymerase chain reaction-restriction fragment length polymorphism method. Major statistical analyses were performed by SAS.ResultsNo significant differences in the genotypic or allelic frequencies of both single-nucleotide polymorphisms were revealed between subjects with and without MTLE (rs11191692: P = 0.890 and 0.230; rs2986017: P = 0.581 and 0.072). Further stratification analysis by gender and age, and analysis of clinical features in relation to MTLE also yielded negative results.Conclusionrs11191692 and rs2986017 of CALHM1 do not contribute substantially to MTLE in Han Chinese.

Long non-coding RNA SNHG15 is a competing endogenous RNA of miR-141-3p that prevents osteoarthritis progression by upregulating BCL2L13 expression

Increasing evidence has demonstrated that the dysregulated expression of long noncoding RNAs (lncRNAs) has important roles in the progression of osteoarthritis (OA), but the function of the lncRNA SNHG15 remains unclear. In the present study, we observed that SNHG15 was downregulated in OA cartilage tissues and IL-1β-induced chondrocytes. The lower expression of SNHG15 was negatively associated with the observed modified Mankin scale scores, extracellular matrix (ECM) degradation and chondrocyte apoptosis. Downregulated expression of SNHG15 increased chondrocyte viability and decreased chondrocyte apoptosis and ECM degradation in vitro and reduced damage to articular cartilage in vivo. Mechanistically, we demonstrated that SNHG15 overexpression promotes the expression of BCL2L13 by sponging miR-141-3p. The higher expression of miR-141-3p was negatively correlated with SNHG15 and BCL2L13 levels in OA cartilage tissues, and a positive correlation was also shown between SNHG15 and BCL2L13 levels. Furthermore, ectopic expression of miR-141-3p or knockdown of BCL2L13 expression could both reduce the effects of SNHG15 on chondrocyte proliferation, apoptosis and ECM degradation. Collectively, these findings reveal that SNHG15 inhibits OA progression by acting as an miR-141-3p sponge to promote BCL2L13 expression, suggesting that knockdown of SNHG15 expression in chondrocytes can be a potential therapeutic strategy to ameliorate OA progression.     

Meta-analysis on the treatment options and outcomes of carotid blood blister aneurysms

ObjectiveCarotid blister aneurysms remain a formidable surgical challenge with varied surgical options. There have been significant advancements in the endovascular management of these aneurysms with the introduction of flow diverters. The comparative risk profiles for different endovascular options compared to surgical management of these lesions is not completely understood.MethodsThe study is a comprehensive systematic review and meta-analysis on the treatment of carotid blood blister aneurysms. Pubmed searches were used to identify relevant articles and patient level data was extracted. Two and three group analyses were conducted comparing surgical and endovascular strategies and surgical, stent coil and flow diversion techniques respectively. Patient outcomes were graded on the modified Rankin Scale with a score of 2 or less defined as favorable.ResultsIn total, 83 studies (41 and 42 studies on surgical and endovascular interventions, respectively) with 1119 patients met our inclusion criteria. A statistically significant difference (at the 5% level of significance) in the effect among three different interventions was not found (Q = 3.41, p = 0.1815) under the random-effect model. Our results did show summary proportions of favorable outcomes were higher in the stent coil (0.87, 95% CI: 0.79 – 0.94) and flow diversion (0.87, 95% CI: 0.75 – 0.96) than that of surgery (0.76, 95% CI: 0.71 – 0.83).ConclusionsOur results suggest a trend towards improved patient outcomes with endovascular techniques compared to surgical strategies but statistical significance was not achieved. We also found that endovascular techniques compare favorably. Increasing retreatments were found to negatively affect patient outcomes.
