OBJECTIVETo study the effect of ginsenoside Rb1 on GSKbeta/IDE signal transduction pathway and Abeta protein secretion in hippocampal neurons of high glucose-treated rats.

METHODHippocampal neurons of 24 h-old newly born SD rats were primarily cultured, inoculated in culture medium under different conditions, and then divided into the normal group, the high glucose group, the LiCl group and the Rb1 group. After being cultured for 72 h, the expressions of their phosphorylated GSK3beta, total GSK3beta and IDE protein were detected by Western blotting analysis. The mRNA expressions of GSK3beta and IDE were determined by RT-PCR. The ELISA assay was used to detect the secretion of Abeta protein in cell supernatant.

RESULTCompared with the normal group, the high glucose group showed increase in the p/tGSK3beta protein ratio and the secretion of Abeta protein and decrease in IDE protein and mRNA (P < 0.05). Compared with the high glucose group, both Rb1 and LiCl groups showed decrease in the p/tGSK3beta protein ratio and the expression of Abeta protein and increase in IDE protein and mRNA expression (P < 0.05). Compared with the LiCl group, the Rb1 group showed no significant difference in the expressions of p/tGSK3beta protein, IDE protein, mRNA and Abeta protein expression. In addition, the GSK3beta mRNA expression of the four groups had no significant difference.

CONCLUSIONGinsenoside Rb1 may reduce the secretion of Abeta protein in hippocampal neurons by reducing the phosphorylation of GSK3beta, down-regulating the ratio of pGSK3beta/GSK3beta and upregulating the expression of IDE.

Objective To compare the diagnostic value of the Standardized Bedside Swallowing Assessment (SSA)and the Scottish Intercollegiate Guidelines(SIC)for bedside dysphagia screening of patients after acute cerebral infarction(ACI). Methods Eighty-six ACI patients within 24 h of stroke onset were enrolled in the study.Within 48 h after hospitalization,swallowing function assessments and dysphagia screenings were carried out with the SSA and SIG,as well as video fluroseopic swallowing studies(VFSSs).The SSA and SIG assessments generated sensitivities,specificities,positive predict values(PPVs),negative predict values(NPVs),positive likelihood ratios (PLRs)and negative likelihood ratios(NLRs).These were compared with the VFSS results. Results The SSA showed a sensitivity of 89.1%,specificity of 75%,PPV of 0.804,NPV of 0.833,PLR of 3.56,NLR of 0.15,and Kappa of 0.648 compared to the VFSS results.The SIG showed a sensitivity of 60.9%,specificity of 82.5%,PPV of 0.800,NPV of 0.647,PLR of 3.44,NLR of 0.47 and Kappa of 0.425 compared to the VFSS.The sensitivity of of the SIG.Both assessments correlated well with the VFSS results. Conclusions Both the SSA and the SIG are elfective in dysphagia screening.The SSA is more sensitive than the SIG and is more suitable for early screening.The SIG is helpful in guiding dysphagia management and evaluating curative effects.

Thirty six patients with hypertriglyceridemia and impaired glucose regulation or newly diagnosed type 2 diabetes, whose fasting plasma glucose was ≤8.0 mmol/L, were treated by fenofibrate for 3 months. Lipid profile, insulin during intravenous glucose tolerance test and oral glucose tolerance test ( including glucose) were measured before and after treatment After treatment, lipid profile was significantly improved. Insulinogenic index (△I30/△G30) and acute insulin response were significantly increased (98. 9vs. 129. 2, 3558.9 vs. 4783. 3 pmol · L - 1 · min - 1, respectively, P ＜ 0. 05 ). Fasting insulin and insulin resistant index in homeostasis model assessment ( HOMA IR) decreased ( 128. 6 vs. 84. 8 pmol/L, 4. 8 vs.3.0, respectively, P ＜0. 05 ). The improvement of insulin secretory function was more significant in patients with higher triglyceride (TG ＞ 3. 3 mmol/L). These results indicate that short-term lipid-lowering treatment with fenofibrate can improve β-cell function and insulin resistance. Patients with higher triglyceride are likely to achieve more benefit from lipid-lowering treatment.

Current materials used for maxillofacial prostheses are far from ideal,and how to develop a final prosthetics material is a significant topic in the research of maxillofacial prostheses.In this paper,some pertinent research of silicone elastomeric materials,such as mechanical properties and colorant are reviewed.

Objective To investigate the ability of dental service in Yunnan province by analyzing the distribution of oral medical institutions,the distribution of oraloral medical staffs,the per capita outpatient costs,and the rate of visiting the doctor.Methods A general survey on oral medical institutions was finished by using questionnaires.Results There were 1045 dental institutions,416 of them were public dental institutions.305 were in Kunming.305 dental institutions were in Kunming,the number of dental institutions per square kilometer was 14.2,the dental manpower index wasl5,the rate of visiting the doctor was 14.19％,per capita outpatient costs were 139.9 Yuan,and the above indexes were ranked first in Kunming.Conclusions In Yunnan province,oral health resources distribution were imbalanced.Dental service ability was uneven,perfect oral disease diagnosis and treatment quality control systems needs to be established,including cultivating specialized nurses relieve the tense situation of oral health care resources,and implenting the four hand operation,so as to effectively improve the quality of medical services.

Objective To explore the effectiveness of long-acting antibacterial material that was used as an intervention in oral care cavity nursing in patients with endotracheal intubation and mechanical ventilation. Methods Patients admitted to Xuzhou Medical College Hospital neurosurgery intensive care unit between 1st December 2013 and 31st August 2014 requiring intubation and mechanical ventilation were enrolled into the study. There were 100 cases randomly selected and were assigned into control group and experimental group by random number table. Each contained 50 cases. Control group used saline for oral care by brushing and irrigation;experimental group used antimicrobial material oral spray in oral care on the top of the method used in control group. The mouth odor, mouth infection rate and ventilator-associated pneumonia (VAP) rate were used to determine. Results About oral odor, mouth infection rate, and VAP rate, the difference of incidences between experimental group and the control group was significant (χ2=4.504-13.728, P <0.05). Conclusions Antimicrobial material can effectively improve oral health in intubated and mechanical ventilated patients. It slows oral acidic environment change, reduces oral infections early onset VAP incidence. And it is worth promoting its use.

Objective To investigate the value of blood culture result in guiding clinical rational use of drugs in clinic.Methods The medical records of 100 children patients with blood culture positive in the four departments of our hospital were retrospectively analyzed.Results The empirical treatment accounted for 98%,the goodness of fit in the medication before culture with the appropriate antibacterial drugs according to final detected bacteria was only 51.6%;after issuing the level 1 report,the adding and substituting drugs in adjusting the antibacterial drugs accounted for about 20% each,60% of antibacterial drugs were not adjusted;after issuing the level 2 report,about 5% of children patients added the antibacterial drugs,the proportion for replacing antibacterial drugs reached 32%,meanwhile the proportion for reducing accounted for 3%;after issuing the level 3 report,the consistency of antibacterial drugs use with the final drug susceptibility test results reached 83%,the inconsistency was only about 5%.Conclusion Clinical pediatric doctors in this hospital still heavily rely on the results of blood culture 3 levels reports,executing antibacterial agents from the experience treatment to the target treatment is also very active.
