A novel NSUN5/ENO3 pathway promotes the Warburg effect and cell growth in clear cell renal cell carcinoma by 5-methylcytosine-stabilized ENO3 mRNA.

Objectives: Clear cell renal cell carcinoma (ccRCC) cells often reprogram their metabolisms. Enolase 3 (ENO3) is closely related to the Warburg effect observed in cells during tumor progression. However, the expression and function of ENO3 in ccRCC cells remain unclear.

Regression of intervertebral disc calcification combined with ossification of the posterior longitudinal ligament: A case report.

Background: Intervertebral disc calcification (IDC) combined with ossification of the posterior longitudinal ligament (OPLL) in cervical discs is rarely reported. This case study presents a rare case of IDC combined with OPLL in the C2-C3 segment.

Case Summary: Here, we present a case of a 6-year-old Asian boy with severe neck pain and stiffness.

Efficacy and safety of electroacupuncture in treatment of cervical spondylosis: A protocol of randomized controlled trial.

Background: Cervical Spondylotic radiculopathy (CSR) is the most common spinal degenerative disease. Its clinical manifestations are pain and numbness in the neck and arm and limitation of neck movement, which greatly affects the life and work of patients. Acupuncture and electroacupuncture are commonly used in China, the efficacy of acupuncture has been confirmed.

Efficacy and safety of Biqi capsule in the treatment of knee osteoarthritis: A protocol of a randomized controlled trial.

Background: Knee osteoarthritis (KOA) is a chronic and degenerative bone and joint disease, with KOA, cartilage degeneration, destruction and subchondral bone remodeling as the main pathological features. Its clinical symptoms are knee pain, swelling, limited activity, and long course of disease can cause joint deformities. At present, the early treatment of Western medicine is mainly the use of nonsteroidal drugs for anti-inflammation and removing pain, but because the efficacy of these drugs is unstable, the disease is easy to repeat after treatment, and the clinical effect is not good.

Dynamic Alterations in Microarchitecture, Mineralization and Mechanical Property of Subchondral Bone in Rat Medial Meniscal Tear Model of Osteoarthritis.

Background: The properties of subchondral bone influence the integrity of articular cartilage in the pathogenesis of osteoarthritis (OA). However, the characteristics of subchondral bone alterations remain unresolved. The present study aimed to observe the dynamic alterations in the microarchitecture, mineralization, and mechanical properties of subchondral bone during the progression of OA.

Bactericidal properties and biocompatibility of a gentamicin-loaded Fe3O4/carbonated hydroxyapatite coating.

Postoperative implant-associated infection remains a serious complication in total joint arthroplasty (TJA) surgery. The addition of antibiotics to bone cement is used as an antimicrobial prophylaxis in cemented joint arthroplasty; however, in cementless arthroplasty, there are no comparable measures for the local delivery of antibiotics. In this study, a gentamicin-loaded Fe3O4/carbonated hydroxyapatite coating (Gent-MCHC) was fabricated according to the following steps: (i) deposition of Fe3O4/CaCO3 particles on Ti6Al4V substrates by electrophoretic deposition; (ii) conversions of MCHC from Fe3O4/CaCO3 coatings by chemical treatment; and (iii) formation of Gent-MCHC by loading gentamicin into MCHC.

[Color Doppler ultrasonic measurements of normal mesenteric lymph nodes in healthy children].

Objective: To assess the value of color Doppler ultrasound in evaluating the mesenteric lymph nodes in healthy children.

Methods: The mesenteric lymph nodes were examined with color Doppler ultrasonography for 730 randomly selected healthy children under 14 years of age, including 410 boys and 298 girls who did not report any recent medical conditions.

Results: Abdominal lymph node detection rate was higher in boys than in girls.

[Enlarged mesenteric lymph nodes in children: a clinical analysis with ultrasonography and the implications].

Objective: To compare the enlarged mesenteric lymph nodes in healthy children with those children with mesenteric lymphadenitis.

Methods: According to the diagnostic criteria defining lymph node enlargement as a 5-mm enlargement or greater in the short diameter, 137 healthy children and 148 children with mesenteric lymphadenitis were retrospectively analyzed for mesenteric lymph node enlargement based on the ultrasonographic data.

Results: The distribution of enlarged mesenteric lymph nodes was detected in the right lower quadrant (RLQ) in 46.

[Preparation of transdermal drug delivery system of felodipine-metoprolol and its bioavailability in rabbits].

To prepare transdermal drug delivery system (TDDS) of felodipine and metoprolol and to study its pharmaceutical characteristics, pharmacokinetics and bioavailability in rabbits, an HPLC assay was established for the simultaneous determination of felodipine and metoprolol in the permeation receptor and patch. The permeation rate and permeation mechanism of felodipine-metoprolol-TDDS through rabbit skin in vitro was examined. The determination of drug content, the examination of content uniformity and stability of the TDDS were carried out.
