Abstract
BACKGROUND Vonoprazan (VPZ)-based regimens are an effective first-line therapy for Helicobacter pylori (H. pylori) infection. However, their value as a rescue therapy needs to be explored.
AIM To assess a VPZ-based regimen as H. pylori rescue therapy.
METHODS This prospective, single-center, clinical trial was conducted between January and August 2022. Patients with a history of H. pylori treatment failure were administered 20 mg VPZ twice daily, 750 mg amoxicillin 3 times daily, and 250 mg Saccharomyces boulardii (S. boulardii) twice daily for 14 d (14-d VAS regimen). VPZ and S. boulardii were taken before meals, while amoxicillin was taken after meals. Within 3 d after the end of eradication therapy, all patients were asked to fill in a questionnaire to assess any adverse events they may have experienced. At least 4-6 wk after the end of eradication therapy, eradication success was assessed using a 13C-urea breath test, and factors associated with eradication success were explored.
RESULTS Herein, 103 patients were assessed, and 68 patients were finally included. All included patients had 1-3 previous eradication failures. The overall eradication rates calculated using intention-to-treat and per-protocol analyses were 92.6% (63/68) and 92.3% (60/65), respectively. The eradication rate did not differ with the number of treatment failures (P = 0.433). The rates of clarithromycin, metronidazole, and levofloxacin resistance were 91.3% (21/23), 100.0% (23/23), and 60.9% (14/23), respectively. There were no cases of resistance to tetracycline, amoxicillin, or furazolidone. In 60.9% (14/23) patients, the H. pylori isolate was resistant to all 3 antibiotics (clarithromycin, metronidazole, and levofloxacin); however, eradication was achieved in 92.9% (13/14) patients. All patients showed metronidazole resistance, and had an eradication rate of 91.3% (21/23). The eradication rate was higher among patients without anxiety (96.8%) than among patients with anxiety (60.0%, P = 0.025). No severe adverse events occurred; most adverse events were mild and disappeared without intervention. Good compliance was seen in 95.6% (65/68) patients. Serological examination showed no significant changes in liver and kidney function.
CONCLUSION VAS is a safe and effective rescue therapy, with an acceptable eradication rate (> 90%), regardless of the number of prior treatment failures. Anxiety may be associated with eradication failure.

Abstract
Objectives The major problem with repair of an articular cartilage injury
is the extensive difference in the structure and function of regenerated,
compared with normal cartilage. Our work investigates the feasibility
of repairing articular osteochondral defects in the canine knee
joint using a composite lamellar scaffold of nano-ß-tricalcium phosphate
(ß-TCP)/collagen (col) I and II with bone marrow stromal stem cells
(BMSCs) and assesses its biological compatibility. Methods The bone–cartilage scaffold was prepared as a laminated composite,
using hydroxyapatite nanoparticles (nano-HAP)/collagen I/copolymer
of polylactic acid–hydroxyacetic acid as the bony scaffold, and
sodium hyaluronate/poly(lactic-co-glycolic acid) as the cartilaginous
scaffold. Ten-to 12-month-old hybrid canines were randomly divided
into an experimental group and a control group. BMSCs were obtained
from the iliac crest of each animal, and only those of the third
generation were used in experiments. An articular osteochondral
defect was created in the right knee of dogs in both groups. Those
in the experimental group were treated by implanting the composites
consisting of the lamellar scaffold of ß-TCP/col I/col II/BMSCs.
Those in the control group were left untreated. Results After 12 weeks of implantation, defects in the experimental group
were filled with white semi-translucent tissue, protruding slightly
over the peripheral cartilage surface. After 24 weeks, the defect
space in the experimental group was filled with new cartilage tissues, finely
integrated into surrounding normal cartilage. The lamellar scaffold
of ß-TCP/col I/col II was gradually degraded and absorbed, while
new cartilage tissue formed. In the control group, the defects were
not repaired. Conclusion This method can be used as a suitable scaffold material for the
tissue-engineered repair of articular cartilage defects. Cite this article: Bone Joint Res 2015;4:56–64

Abstract
The purpose of this study is to determine whether trichostatin A (TSA), a HDAC specific inhibitor, inhibited the induction and functional activity of hypoxia-inducible factor-1 a(HIF-1a) and hypoxia-induced angiogenesis in vitro in human osteosarcoma. The relationship between expression of HIF-1a proteion and angiogenesis in tumor specimens was also studied. Hypoxic regulation of VEGF was studied by RT-PCR, western blotting analysis and enzyme linked immunosorbent assay. The expression of HIF-la and VEGF in human osteosarcoma specimens was studied by immunohistochemical analysis. Under hypoxia, no regulation of HIF-1a mRNA expression was found. However, HIF-1a protein levels increased dramatically in response to hypoxia. Hypoxia increased VEGF mRNA level, but it was significantly inhibited by trichostatin A in a time- and dose-dependent manner (p < 0.05). Strongly positive immunostaining for HIF-1a and VEGF were detectable in the nuclear and cytoplasm of osteosarcoma cells. HIF-1a expressing cells were prominent in areas with high MVD. Significant correlation were found between HIF-1a expression and MVD (p = 0.005, r = 0.767), as well as between VEGF and MVD (p < 0.002, r = 0.701) by Spearman's rank coefficient analysis. These results indicated that HIF-1a is a key factor responsible for angiogenesis by the induction of VEGF. TSA downregulates hypoxia-response genes and hypoxia-induced angiogenesis by the suppression of HIF-1a activity.
