BACKGROUND:Hypoxia inducible factor-2 α(HIF-2α)is one of the key regulators in articular cartilage degeneration and endochondral osteogenesis. OBJECTIVE:To review the regulatory mechanism and application development of HIF-2α in articular cartilage degeneration. METHODS:A computer-based retrieval of PubMed and CNKI databases was performedforrelevant literatures published from January 1990 to October 2015 ,using the key words of “hypoxia inducible factor-2α; osteoarthritis; cartilage” in Chinese and English, respectively. RESULTS AND CONCLUSION:HIF-2α is a transcription factor encoded by the Epas1 gene, which is one of the key regulators in articular cartilage degeneration and endochondral osteogenesis by directly regulating the expressions of various catabolic genes to strengthen cartilage destruction in osteoarthritis. It has been reported that HIF-2α acts on the chondrocytes by regulating the expressions of Wnt/β-Catenin, nuclear factor-κ B, and interleukin-6.

OBJECTIVETo study the clinical efficacy of semiextended intramedullary nailing of the tibia using a suprapatellar approach for proximal tibial fractures.
METHODSFrom January 2013 to January 2014, a total of 16 patients with unilateral proximal tibial fractures, 14 males and 2 females, underwent closed reduction and internal fixation with TRIGEN™ META-NAIL™ via the suprapatellar approach. The average age was 42.2 years old (ranged, 26 to 57 years old). Radiographic and clinical follow-up examinations were performed at a minimum of 1 year after surgery. Measurements included surgery time, complications, bone healing time, tibial alignment, knee range of motion, pain scoring (visual analogue scale) and functional outcome (Lysholm knee score).
RESULTSThe average surgery time was (75.7±8.3) minutes (ranged, 65 to 95 minutes). No obvious complications were recorded. Average duration of follow-up was (15.6±8.1) months (ranged, 12 to 24 months). Fifteen patients attained radiological bone union for a mean time of (3.6±1.8) months (ranged, 3 to 5 months). At the final follow-up, all tibial alignments were good, and no patients complained of anterior knee pain. Mean arc of knee motion was (124.4±18.8) degrees for the affected extremity compared with (127.5±16.7) degrees for the contra-lateral knee. The total scores of Lysholm knee score ranged from 77 to 92, average 86.4±12.3.
CONCLUSIONFor proximal tibial fractures,the semiextended intramedullary nailing technique via a suprapatellar approach can obtain satisfactory clinical outcomes with simplicity in reduction and fixation, minimal complications, and good recovery of limbs function.

Objective To investigate the species composition and quantitative dynamic state of rodent and parasitic flea in Huairou District of Beijing City,and to carry out serologic monitoring of animal plague.Methods Rodent density was investigated at different habitats in eight villages and towns between 2009 and 2011.Serum samples from captured rodents were detected by indirect hemagglutination test,and genotypes of collected parasitic fleas were identified.Results A total of 709 rodents which belong to eight different kinds were captured with a rodent density of 2.52% (83/3 300),and Rattus niviventer and Apodemus peninsulae were dominant species,acounted for 46.4% (329/709) and 18.1%(128/709),respctively.Five hundred and sixty-three serum samples of rodents were tested by plague indirect hemagglutination,and all of them were plague antibody negative.Two hundred fleas were checked with a flea infected rate of 29.63% (48/162),and a flea index of 1.23; Paraceras crispus and Leptopsylla pavlovskii were dominant flea species,a total of 30 and 27,respectively.Conclusion Some environment conditions are suitable for rodents survival,even though there is no sign of animal plague epidemic.
7. Preparation and in vitro evaluation of vitamin K1-loaded erythrocyte drug delivery system
Journal of International Pharmaceutical Research 2020;47(6):444-449
Objective: To establish a vitamin K1(VK1)-delivery system with red blood cells as carrier. Methods: The VK1 self-emulsifying nano-emulsion, micelle and plasma solution were prepared to investigate the VK1 loading on red blood cells. The VK1- chitosan(CS)nanoparticles were prepared with different particle size by the 3 different preparation methods, and the effect of the particle size and charge property on the VK1-loading on red blood cells was investigated with the prepared VK1-CS nanoparticles. The encapsulation efficiency and drug loading were used as main indicators to investigate the appropriate drug loading method. Results: Due to the solubility of VK1 or the charge properties of nanoparticles, the drug loading and encapsulation efficiency of the red blood cell-encapsulated VK1 were quite low, and a large amount of drugs could not be loaded on the red blood cells. The ability of red blood cells to load VK1 was likely related to its Zeta potential. The VK1-CS nanoparticles prepared by the ion condensation method showed a good drug loading performance. Each milliliter of red blood cells could load 174.46 μg VK1 in the nanoparticles, and the loading rate was 85.11%. Conclusion: The VK1 loading by the red blood cells could be achieved by the electrostatic interaction between the positively charged chitosan nanoparticles and the negatively charged erythrocyte membrane.

BACKGROUND: A number of studies have shown that long non-coding RNA DANCR can play an important role in various pathophysiological processes through Wnt/β-catenin signaling pathway.OBJECTIVE: To explore the effect of long non-coding RNA DANCR on the proliferation and chondrogenesis of synovium-derived mesenchymal stem cells.METHODS: Passage 3 synovium-derived mesenchymal stem cells were obtained and transfected with pcDNA3.1-GP (control) and pcDNA3.1-GP(DANCR Homo) (experimental). Cell viability was estimated at 1, 2, 3, 4, 5, 6 and 7 days after DANCR transfection. The passage 3 cells were cultured in the chondriogenic medium for 14 days. And the chondrogenesis potential of cells was examined by toluidine blue staining. The chondrogenic-specific marker genes Aggrecan, Type II collagen (Col2) and Sox9 were determined by Real-time PCR.RESULTS AND CONCLUSION: The synovium-derived mesenchymal stem cells exhibited S-shaped curves in the two groups, with cell arrest at 1-2 days and rapid proliferation beginning at 3 days. Cell counting kit-8 assay and toluidine blue staining showed overexpressing DANCR significantly promoted proliferation in synovium-derived mesenchymal stem cells. The aggregates from synovium-derived mesenchymal stem cells in the experimental group had a greater amount of toluidine blue staining than the control group. In addition, we detected the higher expression of chondrogenic specific marker genes, such as Col2, Sox9 and Aggrecan, in the experimental group than the control group at 14 days after chondrogenic induction (P < 0.05). These results demonstrate that long non-coding RNA DANCR could enhance chondrogenic differentiation and proliferation of human synovium-derived mesenchymal stem cells and increase the expression of chondrogenic specific marker genes.
