SP1 regulates BMSC osteogenic differentiation through the miR-133a-3p/MAPK3 axis : SP1 regulates osteogenic differentiation of BMSCs.

Background: The progression of osteoporosis (OP) can dramatically increase the risk of fractures, which seriously disturb the life of elderly individuals. Specific protein 1 (SP1) is involved in OP progression. However, the mechanism by which SP1 regulates OP progression remains unclear.

MiR-3646 accelerates inflammatory response of Ang II-induced hVSMCs via CYP2J2/EETs axis in hypertension model.

Background: Inflammatory response of human vascular smooth muscle cells (hVSMCs) is a driving factor in hypertension progression. It has been reported that miR-3646 was significantly up-regulated in serum samples from patients with coronary artery disease and acute myocardial infarction mice. However, its role and underlying molecular mechanism related to inflammatory response of angiotensin II (Ang II)-induced hVSMCs remain unclear.

The effect of additional facet joint block for analgesia in patients with thoracolumbar compression fracture undergoing percutaneous kyphoplasty surgery: A protocol for systematic review and meta-analysis.

Background: There is currently no pooled data in the literature to support whether additional facet joint block results in better clinical analgesia after percutaneous kyphoplasty. We assessed the existing evidence on the safety and efficacy of facet joint block in the treatment of patients with thoracolumbar compression fractures undergoing percutaneous kyphoplasty based on qualified trials.

Methods: We will search PubMed, Springer, ScienceDirect, Wanfang, and Cochrane Library databases through April, 2022.

Downregulation of lncRNA SNHG16 inhibits vascular smooth muscle cell proliferation and migration in cerebral atherosclerosis by targeting the miR-30c-5p/SDC2 axis.

Atherosclerosis (AS) is the basic lesion underlying the occurrence and development of cerebrovascular diseases. Abnormal proliferation of vascular smooth muscle cells (VSMCs) plays a crucial role in AS. We aimed to explore the role of SNHG16 in AS and the molecular mechanism of VSMC involvement in the regulation of AS.

[Heat-sensitive moxibustion combined with western medication for low back pain of osteoporosis with kidney- deficiency: a randomized controlled trial].

Objective: To compare the clinical therapeutic effect between heat-sensitive moxibustion combined with western medication and simple western medication for low back pain of osteoporosis with kidney- deficiency.

Methods: A total of 60 patients with osteoporosis were randomized into an observation group (32 cases, 2 cases dropped off) and a control group (32 cases, 3 cases dropped off). In the control group, alendronate sodium tablet and calcium carbonate and vitamin D tablet were taken orally.

[Comparison between pathology and computer for quantitative determination of femoral head necrosis].

Objective: To compare computer measurement semi automatic quantitative detection software system with ultra thin layer pathological section to confirm the avascular necrosis percentage of the femoral head, and provide reference for clinical treatment options.

Methods: From June 2012 to December 2013, the X-ray and MRI of 24 patients(24 hips on unilateral) were reviewed, who had avascular necrosis of the femoral head at late stage (stage III and IV) according to the ARCO international staging system, and performed by total hip arthroplasty. There were 15 males and 9 females, with an average age of (65.

[Association of Toll-like receptor 2 and 4 gene polymorphisms with risk of coronary atherosclerotic artery disease in Hunan Han population].

To explore Toll-like receptor 2 (TLR2) and TLR4 polymorphism in Han people from Hunan region and its association with coronary atherosclerotic heart disease.
 Methods: Sanger sequence and statistical analysis were performed to identify the polymorphism of TLR2 and TLR4 genes in 347 unrelated Hunan Han subjects, including 180 healthy people (control group) and 167 patients with coronary atherosclerotic heart disease (coronary atherosclerotic heart disease group).
 Results: There was no significant difference in the genotype frequency and allelic frequency for TLR2 SNP2258G>A and TLR4 SNP896A>G between the 2 groups (P>0.

Secure multiparty computation of a comparison problem.

Private comparison is fundamental to secure multiparty computation. In this study, we propose novel protocols to privately determine [Formula: see text], or [Formula: see text] in one execution. First, a 0-1-vector encoding method is introduced to encode a number into a vector, and the Goldwasser-Micali encryption scheme is used to compare integers privately.

[A comparative study on the measurement of femoral head necrosis lesions using ultra-thin layer slicing and computer aided identification].

Objective: To compare the differences between computer aided identification and ultra-thin layer slicing in measuring the lesions of femoral head necrosis,and to confirm the accuracy and practicability of computer aided method.

Methods: From June 2012 to December 2013, the X-ray and MRI of 24 patients (24 hips on unilateral) were reviewed, who had avascular necrosis of the femoral head (ANFA) at late stage (stage III and IV) according to the ARCO international staging system. There were 15 males and 9 females, with an average age of (65.

[Progress on treatment of transverse patella fractures with tension band fixation].

Transverse fracture is the most common in patella fracture and tension band fixation is one of the most effective methods. Surgical wire tension band technique is simple, the use of materials is also simple, but it is not strong and difficult to promote. Kirschner tension band technique can get satisfactory reduction with reliable fixation, but it is easy to complicate with steel wire breakage and Kirschner loosening.

[Annlication of external fixator combined with damage control treatment for open fracture of the extremities].

Objective: To investigate the application and effects of external fixator under the guidance of damage control therapy in limb open fracture.

Methods: From May 2008 to January 2013,72 cases with severe limb open fractures (Unincor- porated shock) were divided into control group and observation group (36 cases in each group). In observation group, 36 patients (including 22 males and 14 females) were treated by external fixator at stage I, as soon as possible after waiting for patients physiology conditions being stable,the stage II fracture operation was performed.

[Progress on peri-operative hidden blood loss after hip fracture].

Hip fracture patients preoperative and postoperative exist hidden blood loss which often affect patients' wound healing, increase the probability of infection, prolong rehabilitation exercise, influence postoperative effect. At the same time, the body's blood loss increase the activation of the blood clotting mechanism, promote the incidence of deep vein thrombosis, bleeding and deep vein thrombosis has become the main causes of high risk in hip operation. It is very important to stop bleeding, anticoagulation should not be ignored, so how to effectively deal with the prominent contradiction between the postoperative anticoagulation and bleeding or looking for a best balance has become a intractable problems in hip fracture treatment.
