[Biomechanical study on femoroplasty-augmentation for prevention of osteoporotic hip fractures].

Objective: To explore whether femoral plasty can improve the fracture resistance of osteoporotic femoral specimens and prevent hip fracture, and to compare the difference of mechanical strength changes between two different femoral plasty methods in osteoporotic femoral specimens, so as to determine the best strengthening area of the plasty.

Methods: Eighteen pairs of fresh osteoporotic femur specimens were collected and divided into two groups, A and B, 9 pairs in each group. Nine fresh osteoporotic femur specimens in each group were randomly selected for enhancement, and the corresponding contralateral specimens were used as control group.

rhPDGF-BB combined with ADSCs in the treatment of Achilles tendinitis via miR-363/PI3 K/Akt pathway.

To investigate the mechanism of recombinant human platelet-derived growth factor-BB (rhPDGF-BB) and human adipose-derived stem cells (hADSCs) in the treatment of Achilles tendinitis. Biomechanical indices of stiffness, stress, and maximum load-to-failure were detected by biomechanical test. mRNA and protein levels of miR-363, p-PI3K/AKT, tendon-related genes Collagen I, Scleraxis (Scx), and Tenascin C (TNC) were measured by qRT-PCR and western blot.

[Iincidence of postoperative delirium after hip surgery in elderly patients: a meta-analysis].

Objective: To evaluate incidence of postoperative delirium after hip surgery in elderly patients by meta-analysis.

Methods: From January 1, 2014 to December 31, 2013, clinical literatures about postoperative delirium after hip surgery in elderly patients,were searched from the Pubmed. Literature extract table were formed according to inclusion and exclusion criteria.

Apo E gene polymorphism affects development of type 2 diabetic nephropathy in Asian populations, especially in East Asians: an updated meta-analysis.

Background: Many studies have determined the correlation between the Apolipoprotein E (APO E) gene polymorphisms and diabetic nephropathy, but their results are inconclusive.

Material/methods: With the aim to confirm this correlation, we performed a meta-analysis of 16 studies. The dichotomous data are presented as the odds ratio (OR) with a 95% confidence interval (CI).

Partial greater trochanter osteotomy for hip reduction in total hip arthroplasty for high dislocated hip: a preliminary report.

Background: Hip reduction in total hip arthroplasty for high dislocated hips is difficult. Various femur osteotomy procedures have been used for hip reduction, but these methods increase operative time and risk of nonunion. We investigated the efficacy of a novel partial greater trochanter osteotomy technique for hip reduction in total hip arthroplasty for patients with high hip dislocation.

First report of Endoclita signifer (Lepidoptera: Hepialidae) as a new pest on Eucalyptus.

Endoclita signifier Walker (Lepidoptera: Hepialidae) has become a new wood borer pest in Eucalyptus plantations in southern China. This article documents survey results of its geographic distribution and host plant range in Guangxi and its morphological measurements, life cycle and behavior. In total, 83 Eucalyptus growing counties were surveyed.
