Novel circular RNA 2960 contributes to secondary damage of spinal cord injury by sponging miRNA-124.

Recent studies have shown that circular RNAs (circRNAs) are involved in many human diseases, but their roles in secondary damage after spinal cord injury (SCI) remain unclear. In the current study circRNA sequencing was performed in the damaged tissues of SCI rats on the seventh day after injury, and related molecular mechanisms were investigated. Quantitative PCR validations of molecules that exhibited significantly altered expression in SCI mice were performed.

[Research on coronavirus disease 2019 field disinfection technology for prevention and control].

The coronavirus disease 2019 (COVID-19) epidemic has had a serious impact in the world. In the absence of vaccines and therapeutic drugs, disinfection has become an important technical means to block the spread of the virus. By analyzing the characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we studied a series of disinfection technologies for COVID-19.

Research on Subdivision System of Sin-Cos Encoder Based on Zero Phase Bandpass Filter.

A novel high-precision subdivision system for high-speed encoders is designed in this work. The system is designed with an arc second of Sin-Cos Encoder (SCE) based on zero phase bandpass filter. The system collects the analog output signals of an encoder with a high-speed data acquisition system (DAS); the noise of a digital signal can be effectively eliminated by zero phase bandpass filter with appropriate prior parameters.

Treatment for early postoperative esophageal fistula complicated with anterior cervical surgery.

Object: To investigate the efficacy of debridement, open drainage, and early feeding to treat early esophageal fistula complicated with anterior cervical surgery.

Methods: Retrospective analysis was conducted on data from 3154 patients who had undergone anterior cervical surgeries for cervical vertebra diseases between January 2006 and January 2013, in which eight patients had esophageal fistula with five males and three females. Four patients had cervical spinal injuries and four patients had cervical spondylosis.

[Emission characteristics of PM2.5 from blast furnace iron making].

Electrical low pressure impactor (ELPI) was used to online analyze the PM2.5 particle size and mass concentration distribution in the trapping field and ore tank of blast furnace iron-making plant. Results showed that the grain number concentration of PM2.

[Comparative study of different operating methods in treating old thoracolumbar fractures with spinal cord injury].

Objective: To compare the surgical efficacy of different operating methods for treating old thoracolumbar fracture with spinal cord injury.

Methods: From September 2000 to March 2006, 34 cases of old thoracolumbar fractures with spinal cord injury were treated. Patients were divided into 2 groups randomly.

Treatment of spinal tuberculosis with ultrashort-course chemotherapy in conjunction with partial excision of pathologic vertebrae.

Background Context: The ultrashort-course chemotherapeutical scheme of less than 6 months has been used for part of patients with pulmonary tuberculosis and satisfactory curative effects have already been achieved. However, few systematic and clinical reports so far about medical treatment of spinal tuberculosis by using ultrashort-course chemotherapeutical schemes have been published in the spine-care literature.

Purpose: To assess the results of ultrashort-course chemotherapy (UCC) in conjunction with partial excision of pathological vertebrae for spinal tuberculosis.

[The research of bone morphogenetic protein expression, CT value and mature degree of ossification in the thoracic ossification of ligamentum flavum].

Objective: To investigate the correlation of pathology, bone morphogentic protein (BMP) expression, CT value with the ossification of thoracic ligamentum flavum (TOLF) to afford the evidence to choose appropriate treatment methods.

Methods: Twenty-three patients aged 35 - 65 years old had TOLF in my hospital as case. Their courses of disease were 2 months to 9 years.

[The clinical causes of the thoracic ossification of ligamentum flavum].

Objective: To assess the different causes of thoracic ossification of the ligamentum flavum (TOLF).

Methods: From July 1989 to November 2005, 142 cases were diagnosed the TOLF, in which 121 were operated. The lesions were classified into three types on the basis of the clinical result: (1) In such primary group (Group 1, 90 cases), without incorporation disease and Ca, P and AKP was all normal; (2) In systemic ossified TOLF group (Group 2, 30 cases), 6 cases ankylosing spondylitis, 3 cases DISH, 10 cases fluorosis, 11 cases OPLL; (3) In local spine disease group (Group 3, 22 cases), 5 cases fracture in spine, 4 cases spine TB, 13 cases posterior marginal intraosseous cartilaginous node.
