Objective: This work aimed to evaluate the influence of smear layer on the bonding effectiveness and durability of the self-adhesive resin cements to dentin.

Methods: A total of 48 fresh caries-free third molars with exposed dentin surface were divided into two groups. The dentin surfaces were treated using a standard grit diamond bur (group A) or further polished using a fine grit diamond bur (group B) and then bonded with either of the two self-adhesive resin cements, namely, Clearfil SA Cement (CSA, Kuraray) and Multilink Speed (MS, Ivoclar Vivadent).

Purpose: To investigate the influence of different light irradiation modes on microhardness of dual-curing resin cements.

Methods: The cylindrical specimens (1 mm in thickness and 7.5 mm in diameter) of 5 self-adhesive resin cements (Biscem, Clearfil SA Cement, G-CEM LinkAce, Maxcem Elite and RelyX U100) and 2 universal resin cements(DUOLINK and Nexus 3) were irradiated respectively by a continuous mode (light-curing for 20 s) and a delayed mode (light-curing 5 s + auto-curing 60 s + light-curing 20 s), and then they were placed dry in a light-proof thermostat at 37 degrees centigrade.

Objective: To evaluate the efficacy and safety of acupuncture and moxibustion in the treatment of post-stroke depression (PSD) by regulating the liver and strengthening the root prescription.

Methods: In light of the random controlled trial principle, 123 cases were randomized into an acupuncture-moxibustion group (42 cases), a medication group (40 cases) and an acupuncture + medication group (41 cases). In the acupuncture-moxibustion group, the therapy of regulating the liver and strengthening the root was applied.

Objective: To observe the overexpression of dentin sialophosphoprotein (DSPP) in mouse bone marrow mesenchymal stem cells (BM-MSC) and the expression of specific gene involved in odontogenic and osteogenic differentiation in transfected cells.

Methods: Mouse bone marrow mesenchymal stem cells (BM-MSC) were cultured and then transfected with DSPP gene by adenovirus-mediated way in vitro. The transfection efficiency of DSPP gene was assessed by the marker gene green fluorescent protein (GFP).
