Effect of Ultrasonic Cleaning Combined with Antibacterial Polypeptide Periodontal Gel on Inflammatory Reaction and Incidence of Adverse Reactions in Patients with Chronic Gingivitis.

The purpose of this investigation was to evaluate the efficacy of ultrasonic subgingival curettage in conjunction with antibacterial polypeptide periodontal gel in the management of chronic periodontitis of moderate to severe severity. Methods included dividing 500 hospitalised patients with moderate to severe chronic periodontitis evenly between an observation group and a control group. Subgingival ultrasonic curettage was performed on the placebo group.

[Efficacy and Safety of Bortezomib or Thalidomide Combined with rhEPO in the Treatment of Multiple Myeloma].

Objective: To explore the efficacy and safety of bortezomib or thalidomide combined with recombinant human erythropoietin (rhEPO) in the treatment of multiple myeloma (MM).

Methods: A total of 80 patients with MM who were treated in the Second People's Hospital of Wuhu from January 2013 to December 2018 were selected as the research subjects, and they were divided into bortezomib group (=40) and thalidomide group (=40) by the simple randomization method. The bortezomib group received bortezomib regimen combined with rhEPO therapy, and the thalidomide group was given thalidomide regimen combined with rhEPO therapy, and all patients were treated for 3 courses with every 3 weeks as a course of treatment.

Noise spectrum characteristics of marine pump units induced by different excitation sources.

To study the noise spectrum characteristics of marine pump units induced by different excitation sources, a computational aeroacoustic (CAA) model of the internal and external field noise of a marine pump was established. The coupled acoustic-vibration method was used to obtain the spectrum characteristics of internal and external field noise. The accuracy and feasibility of the simulation method for noise prediction were confirmed through a noise test.

Interleukin-35 suppresses antitumor activity of circulating CD8 T cells in osteosarcoma patients.

: Interleukin (IL)-35 is a newly identified IL-12 cytokine family member and reveals immunosuppressive activity to CD8 T cells in inflammation, infectious diseases, and cancers. However, little is known regarding IL-35 function in osteosarcoma. Thus, the aim of the current study was to investigate the regulatory function of IL-35 to CD8+ T cells in osteosarcoma.

[Research on the synthesis and luminescence characterization of deepen red emission novel polymer].

A deep red emission polymer (PPV-Q) was synthesized successfully. The photoluminescence, electroluminescence and absorption performance of this polymer were studied in detail. The experimental results show that the polymer has strong absorption in the ultraviolet and blue emission wavelength region.
