The following document is a translation of the first national mental health law of the People''s Republic of China, which was adopted by the National People''s Congress on October 26, 2012. The original Chinese version of the law is available at the official government website: http://www.gov.cn/jrzg/2012-10/26/content_2252122.htm. The translation was completed by a team of translators at the Shanghai Mental Health Center at the Shanghai Jiao Tong University School of Medicine. The translators have added footnotes at the end of the document that explain their choices in sections where alternative translations are possible and that provide background information for sections that may be confusing to readers unfamiliar with China. This translation should be cited as follows:ChenHH, Phillips MR, Cheng H, Chen QQ, Chen XD, Fralick D, Zhang YE, Liu M, Huang J, Bueber M.

This study aims to evaluate the drug distribution, tissue concentrations, penetration depth, pharmacokinetic properties, and toxicities after rotational intraperitoneal pressurized aerosol chemotherapy (RIPAC) in pigs. Because relevant medical devices have not been introduced, we developed our prototype of pressurized intraperitoneal aerosol chemotherapy (PIPAC) and RIPAC by adding a conical pendulum motion device for rotating the nozzle. RIPAC and PIPAC were conducted using 150 ml of 1% methylene blue to evaluate the drug distribution and 3.5 mg of doxorubicin in 50 ml of 0.9% NaCl to evaluate the tissue concentrations and penetration depth, pharmacokinetic properties, and toxicities. All agents were sprayed as aerosols via the nozzle, DreamPen® (Dalim Biotech, Gangwon, South Korea), with a velocity of 5 km/h at a flow rate of 30 ml/min under a pressure of 7 bars, and capnoperitoneum of 12 mmHg was maintained for 30 min. As a result, RIPAC showed a wider distribution and stronger intensity than PIPAC. Compared with PIPAC, RIPAC demonstrated high values of the tissue concentration in the central, right upper, epigastrium, left upper, left lower, right lower, and right flank regions (median, 375.5–2124.9 vs. 161.7–1240 ng/ml; p ≤ .05), and higher values of the depth of concentrated diffusion and depth of maximal diffusion (median, 232.5–392.7 vs. 116.9–240.1 μm; 291.2–551.2 vs. 250.5–362.4 μm; p ≤ .05) in all regions except for bowels. In RIPAC, the pharmacokinetic properties reflected hemodynamic changes during capnoperitoneum, and there were no related toxicities. Conclusively, RIPAC may have the potential to enhance drug delivery into the peritoneum compared to PIPAC. 相似文献

Objective
This study analyzed the characteristics of tinnitus identified in anemia patients with cohort- and population-based studies in a single institute and suggests a management algorithm.Methods
Fifty patients who were treated for anemia and referred for tinnitus treatment were included in a single institute retrospective study. Characteristics of tinnitus were investigated in a correlation analysis with demographic and audiologic parameters. For the population-based study, data from the Korea National Health and Nutrition Examination Survey collected between 2010 and 2011 were analyzed. The study population consisted of 11,402 individuals aged 20–97 years with complete tinnitus-related data. The prevalence of tinnitus in anemia patients was investigated using the questionnaire, and associations between tinnitus and blood/urine parameters were evaluated by binary logistic regression analysis.Results
In a single-institute study, patients with non-pulsatile tinnitus were significantly older and their initial hemoglobin was higher than those with pulsatile tinnitus (p = 0.001, 0.008, respectively). In pulsatile tinnitus, age and difference between initial and post-treatment hemoglobin were significantly associated with a subjective improvement in tinnitus (p = 0.002, 0.016, respectively). There were no significant audiologic or hematologic parameters associated with the improvement of non-pulsatile tinnitus. In the population-based study, there was no significant correlation between anemia and tinnitus (p = 0.064). In a multivariate analysis, age was the only parameter associated with tinnitus in participants with anemia.Conclusion
The therapeutic strategy and prognosis of tinnitus in anemia patients differ according to the characteristics of tinnitus and the severity of anemia. 相似文献80.
