[Analysis of the effect of double button plate combined with strengthened anchor in the treatment of acromioclavicular dislocation].

Objective: To evaluate the efficacy and prognosis of double button plate combined with strengthened anchor technique and clavicular hook plate internal fixation for complete acromioclavicular joint dislocation.

Methods: From July 2017 to September 2020, a total of 42 patients with acromioclavicular joint dislocation treated by surgery were choosen as study objects and divided into observation group (21 cases) and control group (21 cases). In the observation group, there were 14 males and 7 females, aged 21 to 63 years old, with an average of (45.

RNF38 inhibits osteosarcoma cell proliferation by binding to CRY1.

The PI3K/AKT pathway plays an important role in the development of osteosarcoma. RNF38 interferes with activation of the AKT pathway. Cryptochrome1 (CRY1) inhibits osteosarcoma proliferation through the AKT pathway.

LncRNA PRNCR1 regulates CXCR4 expression to affect osteogenic differentiation and contribute to osteolysis after hip replacement.

Background: Osteogenic differentiation plays an essential role in the pathogenesis of osteolysis, which is a complication of hip orthroplasty. The roles of lncRNA PRNCR1 in osteogenic differentiation and osteolysis were dissected in this study.

Methods: The expression of PRNCR1, miR-211-5p and C-X-C chemokine receptor-4 (CXCR4) protein in wear particles and mesenchymal stem cells (MSCs) were determined by qRT-PCR and Western blot, separately.

LncRNA PRNCR1 regulates osteogenic differentiation in osteolysis after hip replacement by targeting miR-211-5p.

Osteogenic differentiation and osteolysis after hip replacement are both associated with bone metabolism. Interaction between the long non-coding RNA (lncRNA) prostate cancer non-coding RNA 1 (PRNCR1) and miR-211-5p was analyzed to illuminate their roles in osteogenic differentiation and osteolysis. The expression of PRNCR1, miR-211-5p and C-X-C chemokine receptor-4 (CXCR4) protein in tissues and mesenchymal stem cells (MSCs) were determined by qRT-PCR and western blot, separately.

miR-411 suppresses acute spinal cord injury via downregulation of Fas ligand in rats.

Objective: To explore the role of miR-411/FasL in acute spinal cord injury (ASCI).

Methods: The ASCI rat model was established, and expression of miR-411 and Fas ligand (FasL) was examined. Basso, Beattie and Bresnahan (BBB) score was used to evaluate the rats' neurological function.

[The Advancement of Attenuated Total Reflection Fourier Transform Infrared Technology in Clinical Application].

The authors systemically reviewed the fast development of attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy and its clinical application in the past decades. The advantages of this objective technique include real time scanning, easy manipulation and no harm to the subjects examined. Combined with pattern recognition methodology and further confirmation with the clinical and pathological diagnosis, the goal of fast differentiation of malignancy from benign lesions could be achieved.

A reliable, compact, and repetitive-rate high power microwave generation system.

A compact high power microwave (HPM) generation system is described in this paper. The main parts of the HPM system are a Marx generator with a pulse forming line and a magnetron with diffraction output. The total weight and length of the system are 250 kg and 120 cm, respectively.

[Type A/H1N1 influenza: a clinical summary of 24 imported cases].

Objective: To study the clinical characteristics and laboratory results of 24 confirmed H1N1 influenza cases.

Methods: The characters of clinical, laboratory, iconography and etiology of 24 patients with A/H1N1 were studied, and the changes of T-lymphocyte subsets that between the pre- and post-treatment were evaluated.

Results: The ages of patients were ranged from 6 to 65 years old; average age was 26 years old.
