Erosion, a dynamic process with periods of demineralisation and remineralisation, has become a common problem in modern societies, owing to changes in life style and dietary habits. Although fluorides have been included in toothpastes that claim to prevent demineralisation and aid remineralisation, their ability to remineralise is limited by low concentration of calcium and phosphate ions available in saliva. Hence, a new paste based on casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF), nanohydroxyapatite and bioactive glass (BAG) were introduced.

To evaluate and compare the effects of BAG, nanohydroxyapatite and CPP-ACPF pastes on surface microhardness of demineralised enamel.

48 enamel specimens were randomly divided into five groups Group I positive control - intact specimens and Group II - demineralised specimens. The test groups, Group III, IV and V, comprised CPP-ACPF, nanohydroxyapatite and BAG, respectively. The test specimens were demineralised with 0.1% citric acid followed by remineralisation using either of the three prepared slurries. The specimens were subjected to pH cycling regime for 15 times. The remineralisation potential of the specimens was studied by evaluating the surface microhardness. One specimen from each group was analysed under SEM. Data was tabulated and analysis performed by one way ANOVA and post hoc Scheffe test.

Statistically significant difference was found between the negative control and three test groups based on microhardness evaluation. Nanohydroxyapatite had the least remineralising potential as compared to CPP-ACPF and BAG.

Comparatively, BAG and CCP-ACPF paste showed better remineralising potential.

Incretin hormones, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), can re-sensitize insulin signaling. In a recent phase II clinical trial, the first GLP-1 mimic, exendin-4, has shown reliable curative effect in patients with PD. DA-CH5 is a novel GLP-1/GIP receptor unimolecular co-agonist with a novel peptide sequence added to cross the blood-brain barrier. Here we showed that both exendin-4 and DA-CH5 protected against 6-hydroxydopamine (6-OHDA) cytotoxicity, inhibited apoptosis, improved mitogenesis and induced autophagy flux in SH-SY5Y cells via activation of the insulin receptor substrate-1 (IRS-1)/alpha serine/threonine-protein kinase (Akt)/cAMP response element-binding protein (CREB) pathway. We also found that DA-CH5 (10 nmol/kg) daily intraperitoneal administration for 30 days post-lesion alleviated motor dysfunction in rats and prevented stereotactic unilateral administration of 6-OHDA induced dopaminergic neurons loss in the substantia nigra pars compacta. However, DA-CH5 showed curative effects in reducing the levels of α-synuclein and the levels of pro-inflammatory cytokines (tumor necrosis factor-α, interleukin-1β). It was also more effective than exendin-4 in inhibiting apoptotic process and protecting mitochondrial functions. In addition, insulin resistance was largely alleviated and the expression of autophagy-related proteins was up-regulated in PD model rats after DA-CH5 treatment. These results in this study indicate DA-CH5 plays a therapeutic role in the 6-OHDA-unilaterally lesioned PD rat model and is superior to GLP-1 analogue exendin-4. The study was approved by the Animal Ethics Committee of Shanxi Medical University of China.A new nerve matrix membrane derived from decellularized porcine nerves has been shown to retain the major extracellular matrix components, and to be effective in preventing adhesion between the nerve anastomosis sites and the surrounding tissues in a rat sciatic nerve transection model, thereby enhancing regeneration of the nerve. The effectiveness of the membrane may be attributed to its various bioactive components. In this prospective, randomized, single-blind, parallel-controlled multicenter clinical trial, we compared the safety and efficacy of the new nerve matrix membrane with a previously approved bovine tendon-derived type I collagen nerve wrapping. A total of 120 patients with peripheral nerve injury were recruited from Beijing Jishuitan Hospital, The First Bethune Hospital of Jilin University, and Yantai Yuhuangding Hospital, China. The patients were randomly assigned to undergo end-to-end and tension-free neurorrhaphy with nerve matrix membrane (n = 60, 52 male, 8 female, mean age 41.34 years, exp the results of routine blood tests, liver and renal function tests, coagulation function tests, or immunoglobulin tests at 14 and 180 days postoperatively between the two groups. These findings suggest that the novel nerve matrix membrane is similar in efficacy to the commercially-available bovine-derived collagen membrane in the repair of peripheral nerve injury, and it may therefore serve as an alternative in the clinical setting. The clinical trial was approved by the Institutional Ethics Committee of Beijing Jishuitan Hospital, China (approval No. 20160902) on October 8, 2016, the Institutional Ethics Committee of the First Bethune Hospital of Jilin University, China (approval No. 160518-088) on December 14, 2016, and the Institutional Ethics Committee of Yantai Yuhuangding Hospital, China (approval No. 2016-10-01) on December 9, 2016. The clinical trial was registered with the Chinese Clinical Trial Registry (registration number ChiCTR2000033324) on May 28, 2020.
