Treatment of tibial traumatic osteomyelitis with negative pressure closure drainage combined with open bone grafting or bone migration and its effect on the levels of CRP, TNF-α and IL-6 in the serum.

Objective: To observe the effect of negative pressure closure drainage combined with open bone grafting or bone migration in the treatment of tibial traumatic osteomyelitis.

Methods: Eighty-six (86) cases of tibial traumatic osteomyelitis admitted to Hospital of the Chinese people's Liberation Army from September 2017 to September 2018 were randomly divided into control group and observation group, forty-three (43) cases each. Debridement, open bone grafting or bone migration was given to the control group.

GLIM criteria represent a more suitable tool to evaluate the nutritional status and predict postoperative motor functional recovery of older patients with hip fracture: A retrospective study.

Early recognition of malnutrition is essential to improve the prognosis of older patients with hip fracture. The Nutritional Risk Screening 2002 (NRS-2002), the Short-Form Mini Nutritional Assessment (MNA-SF) and the Global Leadership Initiative on Malnutrition (GLIM) are widely used in malnutrition diagnosis. However, criteria for predicting postoperative hip joint motor function in older patients with hip fractures are still necessary.

A dynamic spatiotemporal model for fall warning and protection.

Early detection of falls is important for reducing fall injuries. However, existing fall detection strategies mostly focus on reducing impact injuries rather than avoiding falls. This study proposed the concept of identifying "Imbalance Point" to warn the body imbalance, allowing sufficient time to recover balance.

Biomechanics and finite element analysis comparing posterior T-plates with LCP for fixation of posterolateral tibial plate fractures.

The treatment for posterolateral tibial plateau fractures (PTPF) have been subjects of controversy. We conducted a study to improve the fixation of PTPF through a lateral approach. We utilized 40 synthetic tibias and categorized the fracture models into five groups based on the locking compression plate (LCP) and T-distal radius plate (TPP) via various forms of fixation with screws through the posterolateral (PL) fracture fragments.

Effect of non-pharmacological interventions on anxiety, depression, sleep quality, and pain after orthopedic surgery: A protocol for systematic review and network meta-analysis.

Background: Patients after orthopedic surgery often experience the pain, anxiety, depression, and sleep disturbances, which can be greatly reduced by non-pharmacologic interventions as alternative therapies. Randomized controlled trials of nonpharmacologic interventions for anxiety, depression, sleep quality, and pain in patients after orthopedic surgery have been reported, but the results may be conflicting. Evidence to determine the optimal non-pharmacological intervention with a high efficacy is limited.

Diosgenin inhibits Wnt/β-catenin pathway to regulate the proliferation and differentiation of MG-63 cells.

Thunb has the effect of anti-osteoporosis, but whether its active ingredient diosgenin (DIO) has an anti-osteoporosis effect is unknown. The purpose of this study is to investigate the effect of DIO on the proliferation and differentiation of MG-63 cells. MG-63 cells were treated with different concentrations of DIO (0.

TFAP2C-mediated LINC00922 signaling underpins doxorubicin-resistant osteosarcoma.

Long noncoding RNAs (lncRNAs) have been indicated as critical regulators in osteosarcoma (OS). However, the function of lncRNAs in doxorubicin (DXR)-resistant OS remain unclear. Here, present study investigated the functions of lncRNA LINC00922 on the DXR resistance in OS tumorigenesis.

Anomalous Mode Transitions in High Power Distributed Bragg Reflector Quantum Cascade Lasers.

In this paper, an anomalous spectral data of distributed Bragg reflector (DBR) quantum cascade lasers (QCLs) emitting around 7.6 μm is presented. The two-section DBR lasers, consisting of a gain section and an unpumped Bragg reflector, display an output power above 0.

Demonstration of High-Power and Stable Single-Mode in a Quantum Cascade Laser Using Buried Sampled Grating.

High-power, low-threshold stable single-mode operation buried distributed feedback quantum cascade laser by incorporating sampled grating emitting at λ ~ 4.87 μm is demonstrated. The high continuous wave (CW) output power of 948 mW and 649 mW for a 6-mm and 4-mm cavity length is obtained at 20 °C, respectively, which benefits from the optimized optical field distribution of sampled grating.

Long noncoding RNA LINC00858 promotes osteosarcoma through regulating miR-139-CDK14 axis.

Long noncoding RNAs (lncRNAs) have been identified to modulate the tumorigenesis of human cancers. The in-depth of lncRNAs on human osteosarcoma oncogenesis is still ambiguous. In present study, functional and mechanism experiments were conducted to investigate the role of long intergenic non-protein coding RNA 00858 (LINC00858) on human osteosarcoma tumorigenesis.

LncRNA DICER1-AS1 promotes the proliferation, invasion and autophagy of osteosarcoma cells via miR-30b/ATG5.

Osteosarcoma is a prevalent primary malignant tumor and long non-coding RNAs (lncRNAs) have been validated to modulate the osteosarcoma tumorigenesis. In present study, our research team investigates the role of a novel identified lncRNA DICER1-AS1 on the tumor progression and autophagy. Results showed that lncRNA DICER1-AS1 was up-regulated in osteosarcoma cells using microarray analysis and RT-PCR.

Investigation of the local dispersion change in anomalous dispersion microcavity and quantitative analysis of the phase-matching in Kerr comb generation.

We numerically simulate Kerr comb generation in an anomalous dispersion microcavity by modal expansion method and demonstrate that the initiation of comb generation is affected by the change of local dispersion possibly caused by avoided mode crossings. We also quantitatively analyze the instantaneous phase matching of different modes and reveal the characteristics of energy distribution in different modes in the dynamics of comb generation. We demonstrate that the local dispersion change can control the Kerr comb to transform between Type I and Type II combs.

Reactions of Chinese adults to warning labels on cigarette packages: a survey in Jiangsu Province.

Background: To compare reactions to warning labels presented on cigarette packages with a specific focus on whether the new Chinese warning labels are better than the old labels and international labels.

Methods: Participants aged 18 and over were recruited in two cities of Jiangsu Province in 2008, and 876 face-to-face interviews were completed. Participants were shown six types of warning labels found on cigarette packages.
