Objective To investigate the combined use of osteoarthritis treatment effect of lornoxicam and peptide drugs.Methods 260 patients with osteoarthritis treated in our hospital from May 2014 to June 2016 were selected, were randomly divided into study group and control group, each group of 130 cases.The patients in the control group were treated with sodium hyaluronate and lornoxicam, the study group was given bone peptide on the basis of the control group. The pain scores, knee function and adverse reactions were compared between the two groups.Results There was no significant difference in VAS and WOMAC scores between the two groups before treatment; after treatment, the improvement of VAS and WOMAC score in the study group was better than that in the control group (P<0.05). There was no significant difference in the incidence of adverse drug reactions between the two groups. Conclusion Sodium hyaluronate, bone peptide, lornoxicam and other drugs in the treatment of patients with osteoarthritis clinical efficacy is obvious, and fewer adverse reactions.

AIM: To investigate the relationship between TRPM3 and diabetes-induced painful peripheral neuropathy. METHODS: Treptozotocin (STZ) was intraperitoneal injected for establishment of diabetic mice model, behavioral tests of paw withdraw thresholds (PWTs) and paw withdraw latencies (PWLs) were conducted; Protein contents and tyrosine phosphorylation levels of TRPM3 were detected by immunoprecipitation and immunoblotting. RESULTS: The PWTs and PWLs in diabetic mice were significantly reduced; TRPM3 tyrosine phosphorylation in the dorsal root ganglia (DRG) of diabetic mice significantly increased compared with control, while the protein expression shows no statistical significance; Enhanced tyrosine phosphorylation of TRPM3 by BPV can evoke heat hyperalgesia in intact mice; Reduce of the tyrosine phosphorylation levels of TRPM3 through PP2 significantly alleviates diabetes-induced heat hyperalgesia, without affecting mechanical allodynia. CONCLUSION: The upregulation of tyrosine phosphorylation of TRPM3 plays a key role in heat related painful diabetic peripheral neuropathy.

Pentostatin is a nucleoside antibiotics with a strong inhibitory effect on adenosine deaminase, and is widely used in the clinical treatment of malignant tumors. However, the high cost hampers its application. In the past 10 years, the biosynthesis of pentostatin were focused on strain breeding, optimization of medium composition and fermentation process. To date, there are no reviews summarizing the elucidated biosynthetic mechanism of pentostatin. This review starts by introducing the various chemical route for production of pentostatin, followed by summarizing the mechanisms of pentostatin biosynthesis in different microorganisms. Finally, challenges for biosynthesis of pentostatin were discussed, and strategies for regulating and improving the microbial synthesis of pentostatin were proposed.
