Objective To investigate the curative efficacy of Guipi granule in treatment of elderly patients osteoporosis with malnutrition and its effects on serum ion levels.Methods A total of 80 patients of osteoporosis with malnutrition in Huzhou Central Hospital from July 2013 to July 2016 in this study were selected and randomly divided into the observation group and the control group with 40 cases in each group.The control group was treated with routine treatment, while the observation group was treated with Guipi granule on the basis of the control group.After three months of treatment, the bone mineral density, leptin, blood calcium, blood phosphorus, alkaline phosphatase, score of TCM syndrome and the treatment effect were compared. Results After treatment, the bone mineral density and leptin in the observation group (0.78 ±0.09)g/cm2, (12.45 ±1.85)ng/mL were higher than the control group (0.69 ±0.07)g/cm2, (9.85 ±1.52 ng/mL)(P <0.05), the blood calcium, blood phosphorus, alkaline phosphatase in the observation group (2.56 ±0.08)mmol/L, (1.43 ±0.13)mmol/L, (33.41 ±9.31)U/L were better than the control group (2.27 ±0.06)mmol/L, (1.85 ±0.21)mmol/L, (39.12 ±10.21)U/L(P<0.05), the total score of TCM syndrome in the observation group (2.85 ±0.32) were lower than the control group (5.03 ±0.49) (P<0.05), the total effective rate of clinical efficacy in the observation group 95.00%(38/40) was higher than the control group 67.50%(27/40)(P<0.05).Conclusion Guipi granule is well for osteoporosis with malnutrition patients, which can effectively improve bone mineral density, maintain the blood calcium and blood phosphorus balance, reduce the level of alkaline phosphatase, relieve the clinical symptoms.

OBJECTIVEThe purpose of this study was to evaluate the color masking ability of Computer Aided Design/Computer Aided Manufacture(CAD/CAM) machining ceramic Vita Mark II, this ability was affected by thickness and shade.

METHODSEach of 5 specimens of 0.5 mm, 1.0 mm and 1.5 mm Vita Mark II A3C/18 and A2C/18 were prepared and the color change was measured after the substrate simulating stained teeth was covered with the specimen.

RESULTSStatistically significant differences (P < 0.01) were recorded in the substrates covered with different thickness and shade of Vita Mark II. The color changes (delta E) were 15.181, 17.691, 19.667 and 15.653, 16.880, 18.002 after the substrates were covered with 0.5 mm, 1.0 mm and 1.5 mm Vita Mark II A3C/18 and A2C/18.

CONCLUSIONAs a dental material, CAD/CAM Vita Mark II has high quality to mask the underlying color. Being a veneer, the masking ability with A2C/18 is better than that with A3C/18, but being an inlay, the result is reverse.

OBJECTIVETo evaluate the resulting color of veneers affected by adding a layer of veneering porcelain on Procera aluminium oxide core.

METHODSFifteen aluminium oxide disks were randomized into three groups. Each of five disks was veneered with porcelain of the Vita shade Al, A2 and B4 respectively. The color of the substrate covered with non-veneered disks and the veneered disks was measured separately and the color differences were calculated.

RESULTSStatistically significant differences (P < 0.01) in color coordinates of dark substrate were recorded between the substrate covered by an aluminium oxide disks and the addition of veneering porcelain to aluminium oxide disks. Mean coordinates color difference (DeltaE, DeltaL *, Deltaa *, Deltab *) after adding the three shades of veneering porcelain showed increase from Al (2.311) to A2 (4.313) to B4 (8.778) in DeltaE, decrease from Al (-1.530) to A2 (-3.369) and B4 (-3.358) in DeltaL *, and increase from Al (-1.440) to A2 (2.198) to B4 (7.955) in Deltab *. The direction of the color modification correlated with values obtained from the liberation. The resulting color was also affected by the color of the underlying structure.

CONCLUSIONThis study illustrates that color of aluminium oxide shell could be modified with feldspathic veneering porcelain, which may be used by practitioners to alter the esthetic outcome of porcelain veneers.

Objectives: The primary aim of this study is to discern the association between specific clinical parameters and low muscle mass (LMM). We endeavor to elucidate the determinants of LMM and the predictive potency of individual factors. Methods: In this retrospective cross-sectional study, we encompassed 450 older adult Chinese participants (252 males and 198 females). Muscle mass quantifications were performed using bioelectrical impedance analysis.Comprehensive data encompassing demographic details (age, sex, height, and weight) and laboratory results (complete blood count, thyroid function, liver function, and renal function) were systematically recorded. Lo gistic regression models, coupled with receiver operating characteristic curve analytics, were employed to ascertain the variables influencing LMM and to evaluate the predictive validity of each parameter on LMM. Results: Upon confounding adjustment for age, gender, body mass index (BMI), and free thyroxine (FT4) persisted as a determinant of LMM. Specifically, individuals with an FT4 exceeding 1.105 ng/dL exhibited a 1.803-fold increased propensity for LMM relative to those with FT4 values below the specified threshold. Incorporating age, gender, BMI, and FT4 in the diagnostic algorithm enhanced the precision of LMM. The results differ between men and women. In the male population, we can still observe that FT4 has a certain value in the diagnosis of LMM, but this phenomenon is not found in the female population. Conclusions Elevated FT4 concentrations, albeit within clinically accepted limits, are inversely associated with muscle mass. As such, FT4 could be postulated as a potential biomarker for LMM in geriatric individuals, especially in the male group.
