Osteoarthritis(OA) is a kind of osteoarticular degenerative disease. The most common joint involvement of OA is knee and hip joint. The incidence rate of OA increases with age. Meta analysis shows that moxibustion is superior to other therapies in treating knee osteoarthritis(KOA). In this study, the effects of moxibustion materials from different places of origin(Hubei Qichun, Henan Nanyang, Hunan) and storage periods(5, 3, 1 years) on knee osteoarthritis in rats were compared. The swelling degree of knee joint and the histopathology of knee joint cartilage were measured. The mechanism of moxibustion in the treatment of knee osteoarthritis was discussed from the perspective of Wnt/β-catenin signaling pathway. The results showed that the swelling degree of knee joint in the moxibustion material group of Hubei Qichun and Henan Nanyang was significantly lower than that in the model group, the diffe-rence was statistically significant(P<0.05), and it was better than that in the moxibustion material group of H and MMP-13 genes in knee cartilage, suggesting that moxibustion could inhibit cartilage base by regulating Wnt/β-catenin signal pathway. It may be one of the mechanisms of moxibustion in the treatment of OA.
Paraoesophageal hernia (PEH) is often symptomatic and reduces patients' quality of life (QoL). There is ongoing debate regarding the most effective surgical technique to repair giant PEH. This study aimed to see if an elective laparoscopic non-mesh composite technique of giant PEH repair offered an advantage in symptom control, hernia recurrence, QoL, morbidity and mortality.

Data were extracted from a prospectively maintained database of patients undergoing hiatal hernia repair. Composite hernia repairs from inception for giant PEH between March 2009 and December 2015 were included. Perioperative mortality, complications, hernia recurrence rates, prevalence, recurrence of symptoms and QoL were included in analysis.

Inclusion criteria were met by 218 patients. Mean age was 70 (49-93). The average hernia size was 62% (range 30-100%; SD 21). There was one perioperative death and three significant complications (Clavien-Dindo grade III and IV). Recurrence rate was 24.8%. Without recurrence, QoL improved significantly across all domains. Recurrence of hiatus hernia reduced QoL. Surgery resulted in resolution of symptoms other than dysphagia which was incompletely improved. Patients' overall satisfaction with surgery was high.

Composite repair of giant PEH is safe with overall good outcomes. Majority of hernia recurrence are small and asymptomatic. Hernia recurrence negatively affected long-term QoL scores.

Microemulsion is an alternative drug delivery system that emerged as a valuable tool to achieve safe formulations for insoluble compounds and to improve their biopharmaceutical properties and pharmacokinetics. This review aims to present the state of the art of microemulsion systems, bringing an overview about their origin and how they can be properly produced and thoroughly characterized by different approaches. Furthermore, comments on regulatory issues regarding stability assessment and toxicity evaluation are discussed. The review concludes with a current opinion on microemulsion systems. The overall objective of this work was to describe all the potentialities of microemulsion systems as a drug carrier for therapeutic purposes, highlighting the unique features of this nanotechnological platform.

Burnout in clinicians is receiving significant attention. Some have proposed that clinicians are experiencing symptoms of moral injury, defined as "perpetrating, failing to prevent, bearing witness to, or learning about acts that transgress deeply held moral beliefs and expectations." Current efforts to improve the electronic health record (EHR) have focused on improving the user experience to reduce burden that has been identified as a contributing factor to provider burnout. However, if EHRs are contributing to moral injury, improvements to user experience will not eliminate the effects on providers. Current research has not evaluated the risk for moral injury resulting from the use of EHRs. This Perspective reviews the differences between burnout and moral injury, discusses the implications for clinicians using EHRs, and highlights the need for research to better define the problem.Spectral CT has great potential for a variety of clinical applications due to the improved material discrimination with respect to conventional CT. Many clinical and preclinical spectral CT systems have two spectral channels for dual-energy CT using strategies such as split-filtration, dual-layer detectors, or kVp-switching. However, there are emerging clinical imaging applications which would require three or more spectral sensitivity channels, for example, multiple exogenous contrast agents in a single scan. Spatial-spectral filters are a new spectral CT technology which use x-ray beam modulation to offer greater spectral diversity. The device consists of an array of k-edge filters which divide the x-ray beam into spectrally varied beamlets. This design allows for an arbitrary number of spectral channels; however, traditional two-step reconstruction-decomposition schemes are typically not effective because the measured data for any individual spectral channel is sparse in the projection domain. Instead, we ons of spectral CT.
