BACKGROUND: Most of the dental metal repair materials contacting Ti implants will cause galvanic corrosion and local environment with positive electricity on the implant interface, which directly affects the status of the tissues, especially bone resorption.OBJECTIVE: To evaluate the galvanic corrosion of commercially pure Ti (TA2 type) coupled with Au alloy, CoCr alloy, Ti alloy, and NiCr alloy in vitro. METHODS: Circuit of commercially pure Ti contacting with Au alloy, CoCr alloy, Ti alloy, and NiCr alloy was simulated in vitro in artificial saliva, and the common potential and galvanic current in 15 hours were recorded to draw current-time curves. RESULTS AND CONCLUSION: The galvanic current became stable after 8 hours of contacting. The galvanic current was the greatest in Ti/Au, followed by Ti/CoCr, Ti/Ti alloy, and then Ti/NiCr. Results indicated that the galvanic corrosion of the couple of Ti and Au alloy is the lowest. Au alloy is the most suitable material for implant superstructure. The galvanic corrosion of the couple of Ti and NiCr alloy is the highest, so NiCr alloy is not acceptable for implant superstructure.

Object An attempt to seek after an intrinsic inhibitor present in the seed of Astragalus membranaceus (Fisch.) Bge.. Methods Crude ethereal extract of the seed was prepared and treated on paper chromatography. Inhibitory effects of different fractions with different Rf value were tested on Brassica chinensis L. and wheat germination. Effect of steeping the seed in warm water at 41 ℃ or 45 ℃ for different periods of time was also studied.Results Seed of A. membranaceus does contain strong intrinsic inhibitor. The portion of its ethereal extract with Rf 0.9 showed the most strong inhibition for the germination of Brassica, and the fraction with Rf 1.0 can inhibit the growth of the tender Brassica root, steeping with warm water can remove most of the intrinsic inhibitor, which also inhibits the growth of both aerial and underground parts of wheat sprouts, but without effect on its seed germination. It also showed strong inhibition of seed germination and growth of tender root of A. membranaceus. Conclusion Besides the low water permeability of the seed peel, the intrinsic inhibitor present in A. membranaceus is another essential factor that retard its germination.

The advances on novel immunotherapeutic targeted agents in NHL will be comprehensively reviewed in this paper from three aspects, including the targeted monoclonal antibody of cell surface antigen, the targeted therapy of cell signal transduction pathway and lymphoma microenvironment.

Objective Based on the 2012 Atlanta classification criteria, to study the value of C-reactive protein (CRP) and procalcitonin (PCT) in the early forecasting acute pancreatitis (AP). Methods Eighty-three patients with AP were selected. The patients were divided into mild AP (MAP) group (39 cases), moderately severe AP (MSAP) group (31 cases) and severe AP (SAP) group (13 cases) according to the 2012 Atlanta classification criteria. Twenty-seven healthy people were selected as control group. The levels of serum CRP and PCT were measured. The predictive value of serum CRP and PCT levels for SAP, infectious pancreatic necrosis (IPN), organ failure and death risk was assessed using the area under the curve (AUC). Results The serum CRP and PCT levels in MAP group, MSAP group and SAP group were significantly higher than those in control group: (49.84 ± 12.26), (89.77 ± 22.10) and (123.69 ± 37.09) mg/L vs. (3.92 ± 1.37) mg/L, (1.15 ± 0.42), (2.44 ± 0.61) and (3.27 ± 0.96)μg/L vs. (0.41 ± 0.13)μg/L, and those in MSAP group and SAP group were significantly higher than those in MAP group, those in SAP group were significantly higher than those in MSAP group, and there were statistical differences (P<0.05). The Spearman correlation analysis result showed that AP severity was positively correlated with serum CRP and PCT levels (r = 0.652 and 0.714, P<0.05). The accuracy of serum CRP level for forecasting SAP and IPN was medium (AUC = 0.73 and 0.76), and for forecasting organ failure accuracy was low (AUC = 0.67). Serum CRP showed no significance in forecasting death risk (AUC = 0.46). The accuracy of serum PCT level for forecasting SAP, IPN and death risk accuracy was medium (AUC = 0.71, 0.86 and 0.80), and for forecasting organ failure accuracy was low (AUC =0.64). Conclusions Based on the 2012 Atlanta classification criteria, the accuracy of serum CRP level for forecasting SAP is higher than that of serum PCT level, the accuracy of serum PCT level for forecasting IPN and death risk is higher than that of serum CRP level, and accuracy of serum CRP and PCT levels for forecasting organ failure are low.

Toll-like receptors are an important pattern recognition receptors that recognize specific components of microbes and certain host molecules.Through initiated cell signaling pathway,they can induce immunocyte.Their activation triggers the innate immune response,and is crucial to the successful induction of Th1/Th2-phenotyped adaptive immunity.This review will give a brief overview of our current knowledge of TLRs as key components in immune responses and their regulation in respiratory tract diseases such as asthma.

With the development of computer techniques and medical imaging examining methods , precise radiotherapy is becoming the major direction of radiotherapy for tuomors. Both of tumor control probability and normal tissue complication probability are improved with precise radiotherapy. This paper critically review the value of PET-CT and breathing control in precise radiotherapy for non-small-cell lung cancer (NSCLC).

AIM: To study central corneal thickness ( CCT ) and correlation in different degrees of diabetic retinopathy ( DR) .
METHODS:A total of 65 cases (130 eyes) with different degrees of DR and 35 normal cases (70 eyes) as the age-and gender-matched control group were examined by corneal endothelial microscope, to measure CCT and statistics
RESULTS: Compared to control group, there were no significant difference of CCT both mild and medium nonproliferative diabetic retinopathy ( NPDR) groups ( P>0. 05 ). While the CCT of severe NPDR group and proliferative diabetic retinopathy ( PDR ) group were thicker than control group, and the differences were statistically significant (P<0. 05); Pairwise comparison in different degrees of DR groups: the CCT of severe NPDR and mild NPDR groups were thicker than PDR group, and the differences were statistically significant ( P<0. 05 );compared to medium NPDR, the CCT of PDR was thicker (P<0. 05);The thickness of CCT increases with severity of DR, there was positive linear correlation ( r=0. 173, P<0-05).
CONCLUSION: The CCT increases with severity of DR. Taking care of protecting corneal endothelium is very important in the time of therapeutic measure, especially intraocular operation, to decrease complication.
