Objective To explore the effects of exogenous methionine on arsenical distribution in liver,blood and brain of mice exposed to sodium arsenite through drinking water. Methods The female Kunming mice were randomly divided into control group, the alone arsenic exposure group , the low level methionine intervention group, the moderate level methionine intervention group and the high level methionine intervention group, eight mice in each group . The mice in the experimental groups were exposed to sodium arsenite through drinking water at 50 mg/L arsenic for four consecutive weeks. And at the fourth week the 5 groups were treated intraperitoneally with saline solution (control and As group),100 mg/kg b.w,200 mg/kg b.w or 400 mg/kg b.w methionine,respectively . Twenty-four hours after cessation of methionine administration,mice were anaesthetized and rapidly dissected. The samples of blood,liver and brain were removed immediately for arsenic species analysis. Levels of inorganic arsenic (iAs),monomethylarsonic acid (MMA) and dimethylarsenic acid (DMA) were determined by HG-AAS method. Then total arsenic speciation( TAs), primary methylation ratio( PMR)and secondary methylation ratio( SMR)in each tissue were calculated. Results Compared with the control group, the levels of iAs, MMA, DMA and TAs in liver, brain and blood, were significantly higher in all experimental groups ( P

Objective:To summarize the current policies and measures in curbing health corruption in China, and to evaluate the implementation results of these policies and measures.Methods:We made a systematic review to search and screen the literatures, with related thematic information extracted, compared and classified to form an integrated view by the data integration method of thematic synthesis.Results:A total of 147 literatures were included, covering such health policies and measures as the basic drug system, the centralized bidding and purchasing and centralized drug purchasing, the " two-invoice system" , hospital information disclosure system, adverse records of commercial bribery, doctor′s virtue evaluation system and no bribery agreement. These five policies and measures prove effective in curbing the corruption, but some types of corruption tend to evade such restrictions.Conclusions:The five types of policy measures summarized in the study have effectively curbed the high risk exposure of corruptions found in drugs, medical consumables and medical devices, and also guided and restrained the profit-oriented behaviors of the behavior subjects. Stronger measures should be integrated into a broader reform of the healthcare system, in combination with institutional compensation and operational mechanism reform, medical personnel compensation and incentive system, and modern pluralistic governance reform. Meanwhile, studies in the field of corruption need to focus on the direct and indirect effects of multi-level medical reform policies on corruption governance from an integrated perspective, while attention needs to cover more types of corruption behaviors, and to diversify research methods, so as to provide more practical policy support.

ObjectiveTo analyze the relationship between the patients' psychological factors and esthetics satisfaction of all-ceramic restoration of anterior teeth.MethodsThe N scales of Eysenck personality questionnaires (EPQ) were filled at the first visit,and the total scores of N scales were calculated.After restorative treatments,the satisfaction questionnaire was used to evaluate the patients' aesthetic satisfaction on material quality,color,geometry,profile,self-confidence,etc,and to analyze the relation between psychological factors and satisfaction of the patients.ResultsThe scores of EPQ N scale of the patients in this study were as follows:Nmax=23,Nmin =3,Navg =9.35±5.714.The patients had high satisfaction with restoration.Aesthetic satisfaction,color and self-confidence were in relation to the N scales scores,satisfaction of color was in relation to sickness suspicion,satisfaction of profile was in relation to enthrallment extent and guilty consciousness,and satisfaction of self-confidence improvement was in relation to anxiety and self-determination.Conclusions The psychologic factor of the patients has some influence on the esthetics satisfaction of all-ceramic restoration of anterior teeth.

BACKGROUND:Stem cels from the apical papila are a new kind of mesenchymal stem cels, and whether it can
be used in root regeneration is the key to the present study. OBJECTIVE:To culture rat stem cels from the apical papila and periodontal ligament stem celsin vitro, and to compare the biology behaviors of these two kinds of cels, thereby providing experimental basis for the application of stem cels from the apical papila in root regeneration. METHODS:The apical papila, as wel as the periodontal ligament tissues from the healthy mandibular teeth of young rats were digested and cultured. Immunophenotypes of stem cels from the apical papila and periodontal ligament stem cels were detected by immunofluorescence technique. Then, cel growth curves were determined by MTT method and mineralized nodule formation was observed by alizarin red staining. RESULTS AND CONCLUSION:Stem cels from the apical papila and periodontal ligament stem cels were both positive for STRO-1. Stem cels from the apical papila were positive for CD90 and weakly positive for CD146. Periodontal ligament stem cels were positive for CD146 and weakly positive for CD90. The absorbance values of stem cels from the apical papila and periodontal ligament stem cels increased with the increasing of time and became stable at 8 days. Since the 4th day, the proliferation capacity of stem cels from the apical papila was significantly stronger than that of periodontal ligament stem cels (P < 0.05). Both of stem cels are visible to have mineralized nodule formation. Compared with the periodontal ligament stem cels, stem cels from the apical papila were stained obviously deeper and had more mineralized nodules. These results show that stem cels from the apical papila have stronger proliferation capacity and mineralization ability than periodontal ligament stem cels.

Objective To investigate the risk factors for early neurological deterioration (END) in patients with ischemic stroke. Methods The consecutive patients with new acute ischemic stroke within 24 h were enrol ed. They were divided into either an END or a non-END group. Their relevant medical history, baseline clinical data, imaging examinations and laboratory test results in both groups were compared. Results A total of 95 patients with acute ischemic stroke were enrol ed, including 32 in the END group and 63 in the non-END group. There were significant differences in the proportion of patients in diabetes mel itus (χ2 =6. 081, P=0. 014), baseline National Institutes of Health Stroke Scale (NIHSS) score >15 (χ2 =9. 851, P=0. 002), baseline infarct volume >30 cm3 (χ2 =10. 815, P=0. 001), and fever (χ2 =6. 642, P=0. 010), as wel as the fasting glucose (t=2. 632, P=0. 010), homocysteine (t =2. 997, P=0. 003), C-reactive protein (t=2. 349, P=0. 021), baseline NIHSS (Z=497. 5, P=0. 001), and baseline infarct volume (Z=544. 5, P<0. 001) between the 2 groups. Furthermore, there were significant differences in the proportions of patients in large artery atherosclerotic stroke (χ2 =24. 539, P<0. 001 ) and smal arterial occlusive stroke (χ2 = 27. 913, P< 0. 001 ) in the TOAST classification, as wel as the total anterior circulation stroke (χ2 =7. 578, P<0. 006) and partial anterior circulation stroke (χ2 =4. 818, P<0. 028) in the OSCP classification. Multivariate logistic regression analysis showed that fasting glucose >6. 0 mmol/L (odds ratio [OR] 6. 951, 95%confidence interval [CI] 2. 159-22. 348; P=0. 001), homocysteine >15 μmol/L (OR 3. 301, 95% CI 1. 028-10. 595; P=0. 045), NIHSS score >15 (OR 4. 174, 95% CI 1. 772-14. 870;P=0. 028), infarct volume >30 cm3 (OR 4. 996, 95% CI 1. 334-18. 717; P=0. 017), and fever (OR 4. 528, 95% CI 1. 334-15. 372;P=0. 015) were the independent risk factors for occurring END in patients with acute ischemic stroke. Conclusions The baseline glucose, NIHSS score, infarct volume, homocysteine, and increased body temperature are the independent risk factors for occurring EDN in patients with acute ischemic stroke.
