[Influence of wind, cold and dampness on clinical manifestation of knee osteoarthritis patients based on the stratifications of traditional Chinese medicine constitution].

Objective: To explore influence of external factors of wind, cold and dampness on clinical symptoms in knee osteoarthritis (KOA) patients with different constitutions of traditional Chinese medicine.

Methods: A cross-sectional stratified study was performed to select 108 patients with GradeⅡKOA in Kellgren & Lawrence (K-L) classification, including 22 males and 86 females, aged from 47 to 75 years old with an average of (60.7±6.

Artificial intelligence method for predicting the maximum stress of an off-center casing under non-uniform ground stress with support vector machine.

Unlabelled: The situation of an off-center casing under non-uniform ground stress can occur in the process of drilling a salt-gypsum formation, and the related casing stress calculation has not yet been solved analytically. In addition, the experimental equipment in many cases cannot meet the actual conditions and the experimental cost is very high. These comprehensive factors cause the existing casing design to not meet the actual conditions and cause casing deformation, affecting the drilling operation in Tarim oil field.

[Effect of acupuncture therapy on patients with low back pain: a Meta-analysis].

Objective: To systematically review the clinical efficacy of acupuncture on the patients with low back pain (LBP).

Methods: Randomized controlled trials (RCTs) about pure acupuncture therapy versus other treatments in treating LBP were electronically searched in PubMed, CBM, EMbase, The Cochrane Library, CNKI, VIP and Wanfang Data from January 2004 to May 2014. The observed index on the results were the changed scores of VAS, ODI, JOA and RMDQ.

[Regulating effect of anodonta glucan HBP-A on chondrocytes through Wnt pathway].

Objective: To investigate regulation function of anodonta glucan HBP-A on chondrocytes through Wnt pathway in vitro.

Methods: Rat chondrocytes were cultured and differentiated induced with IL-1beta (10 ng/ml) in vitro. Chondrocytes were divided into five groups:IL-13 group,IL-1beta + IWP-2 (5 microM,Wnt pathway inhibitor) group, IL-1beta + HBP-A (0.
