Resumo: Antecedentes: Com o contínuo aumento da prevalência da doença de Alzheimer (DA), a reconciliação medicamentosa no tratamento de pacientes portadores da doença é também iminente. Objetivo: Explorar o papel e a importância da reconciliação medicamentosa no tratamento de DA. Métodos: 100 pacientes com mais de 65 anos de idade com diagnóstico de DA foram divididos aleatoriamente em dois grupos: tratamento convencional (CON) e mudança medicamentosa (MED). A relação das prescrições médicas de todos os indivíduos foi obtida dentro das 24 horas após a admissão, usando-se os critérios Beers, os critérios STOPP / START, e a Farmacopéia Chinesa foi usada como intervenção no grupo MED. A reconciliação medicamentosa foi realizada em 2 semanas, 1 mês e 2 meses após a admissão hospitalar. O número de medicamentos prescritos, a quantidade de medicamentos, a taxa de erro de medicação, o efeito terapêutico, as reações adversas a medicamentos e os níveis de satisfação dos familiares e cuidadores principais foram comparados entre os dois grupos. Resultados: Após a intervenção, os tipos e a quantidade de medicação no grupo MED foram menores em comparação com o grupo CON, juntamente com uma taxa de erro de medicação reduzida. A pontuação do mini-exame do estado mental (MEEM) e a proporção de pacientes bem nutridos no grupo MED foram maiores do que no grupo CON. Observou-se também que o escore da habilidade física de autocuidado e a proporção de pacientes com deglutição alterada foram menores quando comparados ao grupo CON. A incidência de reações adversas a medicamentos no grupo MED foi menor do que no grupo CON. Por outro lado, o índice de satisfação foi superior ao do grupo CON. Conclusão: A reconciliação medicamentosa pode reduzir os erros de medicação em pacientes com DA.

ABSTRACT Background: With the continuous increase of Alzheimer's disease (AD), it is also imminent to treat patients with AD for medication reconciliation. Objective: To explore the role and value of medication reconciliation in AD treatment. Methods: 100 patients over 65 years of age diagnosed with AD were randomly separated into two groups: conventional treatment and medication reforming. The list of medical orders of all subjects was obtained within 24 hours after admission with Beers criteria, STOPP/START criteria, and Chinese Pharmacopoeia used as the MED intervention criteria. Medication reconciliation was performed at 2 weeks, 1 month, and 2 months after hospital admission. The number of medications prescribed, the quantity of the medication, medication error rate, therapeutic effect, adverse drug reactions, and satisfaction levels of family members and main caregivers were compared between the two groups. Results: After the intervention, the types and amount of medication in the MED group were less compared to the CON group along with a reduced medication deviation rate. The Mini-mental state examination (MMSE) score and the proportion of well-nourished patients in the MED group were higher than those in the CON group. It was also observed that the physical self-care ability score and the proportion of patients with abnormal swallowing were lower when in comparison with the CON group. The incidence of adverse drug reactions in the MED group was lower than that in the CON group. However, the satisfaction rate was higher than that in the CON group. Conclusion: Medication reconciliation can reduce the medication deviation in AD patients.

ABSTRACT Urban rainfall runoff pollution has become a major reason for water eutrophication problem in the process of urbanization in China, while phosphorus is a significant restrictive factor that influences primary productivity of freshwater system. It's rather significant to conduct phosphorus control in waste water with engineering measures. This research, based on material balance research of phosphorus in artificial wetlands, HRT (hydraulic retention time) and analysis of wetland plant photosynthesis and removal rate of phosphorus, simulates purification of phosphorus in urban runoff sewage by artificial wetland system. Experiment shows that removal rate of total phosphorus in urban runoff sewage by artificial wetland system reaches 42.23%-60.89%, and contribution rate in removal of phosphorus which is assimilated and absorbed by plants is 14.74%; contribution rate in removal of phosphorus which is accumulated and absorbed by substrates is 43.22%; contribution rate in removal of phosphorus which is absorbed by means like microorganisms is 2.93%. Pollutant absorption by substrates is a process of dynamic equilibrium. With extension of HRT, phosphorus removing effect of wetlands present an increasing and then decreasing tendency; Net photosynthetic rate and TP removal rate of canna and reed have significant positive correlation, and correlation coefficients are respectively 0.941(P<0.001) and 0.915(P<0.05). Substrates and plants are main pathways for phosphorus removal of artificial wetlands, covering 95% of the total removing effect.

The aim was to understand the anatomical features of the venous valve in Macaca fascicularis and to compare it with that of humans. The bilateral lower limbs (24 limbs from 12 animals) of Macaca fascicularis cadavers were dissected, and the femoral veins (FVs) were equally divided into distal, intermediate, and proximal sections. The external diameter of the FV in each section was measured. The venous valves were observed microscopically and stained with hematoxylin and eosin as well as trichrome. Data describing the human venous valve were collected from the current literature. No great saphenous veins were found among the 24 lower limbs from the Macaca fascicularis cadavers. The external diameters of the FVs in the distal, intermediate, and proximal sections were 3.53 ± 0.37 mm, 3.42 ± 0.55 mm, and 3.37 ± 0.54 mm, respectively. In most cases, there was one venous bivalve located in the FV approximately 0-2.71 mm below the junction of the FV and the deep femoral vein. Endothelium covered the luminal and sinusal surfaces of the leaflets. Abundant collagen fibers were found under the endothelial cells beneath the luminal surface of the leaflets. An elastin fiber network was located under the sinus endothelial surface. Smooth muscle cells in the FV extend to the edge of the valve. The venous valve of Macaca fascicularis is similar to that of humans, both morphologically and histologically. However, there is only one venous bivalve and no great saphenous vein in Macaca fascicularis.

El objetivo fue comprender las características anatómicas de la válvula venosa en Macaca fascicularis y compararla con la de los humanos. Fueron disecados bilateralmente los miembros pélvicos (24 miembros de 12 animales) de cadáveres de Macaca fascicularis; las venas femorales (VF) fueron divididas en secciones distal, media y proximal. Se midió el diámetro externo de las VFs en cada sección. Las válvulas venosas se observaron microscópicamente y se tiñeron con H-E y tricrómico. Los datos para describir la válvula venosa humana se obtuvieron desde la literatura. No se encontraron venas safenas magnas entre los 24 miembros inferiores. Los diámetros externos de las VFs en las secciones distal, media y proximal fueron 3,53±0,37 mm, 3,42 mm±0,55, y 3,37±0,54 mm, respectivamente. En la mayoría de los casos, hubo vena bivalva situada aproximadamente 0-2,71 mm debajo de la unión de la VF y la vena femoral profunda. El endotelio cubrió las superficies luminal y sinusal. Se observaron abundantes fibras de colágeno en las células endoteliales bajo la superficie luminal de las válvulas. Una red de fibras de elastina se encontró bajo la superficie del seno endotelial. Las células musculares lisas en las VFs se extiendían hasta el margen de la válvula. La válvula venosa del Macaca fascicularis es similar a la de los seres humanos, morfológica e histológicamente. Sin embargo, sólo hubo una vena bivalvular, y no se observaron venas safenas en Macaca fascicularis.

Thymosin alpha 1 (Tα1) has been shown to have beneficial effects on numerous immune system parameters, but little is known about the effects of Tα1 on patients with gastric carcinoma. The objective of this study was to determine the effect of Tα1 on subpopulations of Th1, Th2, Th17, and regulatory T cells (Tregs) in vitro, and to evaluate its efficacy as an immunoregulatory factor in patients with gastric carcinoma. We compared the effect of Tα1 on the frequency of CD4+ and CD8+ T cells, especially the CD4+CD25+Foxp3+ Tregs in peripheral blood mononuclear cells (PBMCs) from gastric carcinoma patients (N = 35) and healthy donors (N = 22). We also analyzed the changes in the proliferation of PBMCs in response to treatment with Tα1, and examined the production of Th1, Th2, and Th17 cytokines by PBMCs and tumor-infiltrating lymphocytes. The treatment of PBMCs from gastric cancer patients, with Tα1 (50 µg/mL) alone increased the percentage of CD4+CD25+Foxp3+ (suppressive antitumor-specific Tregs) from 1.68 ± 0.697 to 2.19 ± 0.795% (P < 0.05). Our results indicate that Tα1 increases the percentage of Tregs and IL-1β, TNF-α, and IL-6 in vitro.

OBJECTIVE: We aimed to determine the burden of bacillary dysentery in China, its cross-regional variations, trends in morbidity and mortality, the causative bacterial species and antimicrobial resistance patterns. METHODS: We extracted and integrated governmental statistics and relevant medical literature published from 1991 to 2000. Data were also collected from one general hospital each for the six provinces and Jin-an district, Shanghai, representative of six geographical regions and a modern city. FINDINGS: In 2000, 0.8-1.7 million episodes of bacillary dysentery occurred of which 0.5 to 0.7 million were treated at health-care facilities and 0.15-0.20 million patients were hospitalized. The highest morbidity and mortality rates were among the youngest and oldest age groups. Bacillary dysentery peaked during the summer months. The major causative species was Shigella flexneri (86%) and the predominant S. flexneri serotype was 2a (80%). About 74-80% of Shigella isolates remained susceptible to fluorinated quinolones. CONCLUSION: We conclude that while morbidity and mortality due to bacillary dysentery has decreased considerably in China in the past decade due to increasing access to affordable health care and antibiotics, a considerable burden exists among the youngest and oldest age groups and in regions with low economic development. We suggest that while a vaccine would be effective for short- and medium-term control of bacillary dysentery, improved water supply, sanitation, and hygiene are likely to be required for long-term control.

OBJETIVO: Decidimos determinar la carga de disentería bacilar en China, las diferencias interregionales en ese sentido, las tendencias de la morbilidad y la mortalidad, las especies bacterianas causantes, y la distribución de la resistencia a los antimicrobianos. MÉTODOS: Procedimos a extraer e integrar estadísticas gubernamentales y publicaciones médicas relacionadas aparecidas entre 1991 y 2000. También obtuvimos datos de un hospital general de cada una de las seis provincias consideradar y del distrito de Jin-an, Shanghai, como información representativa de seis regiones geográficas y una ciudad moderna. RESULTADOS: En 2000 se produjeron entre 0,8 y 1,7 millones de episodios de disentería bacilar, de los cuales 0,5 - 0,7 millones fueron tratados en establecimientos de salud, y 0,15 - 0,20 millones fueron hospitalizados. Las mayores tasas de morbilidad y mortalidad fueron las registradas entre los grupos más jóvenes y en las personas mayores. La disentería bacilar alcanzó la máxima cota en los meses de verano. La principal especie causante fue Shigella flexneri (86%), con la variante 2a como serotipo predominante (80%). Aproximadamente un 74% - 80% de las colonias de Shigella seguían siendo vulnerables a las quinolonas fluoradas. CONCLUSIÓN: Aunque la morbimortalidad por disentería bacilar ha disminuido considerablemente en China durante el último decenio, gracias al mayor acceso a la atención sanitaria y los antibióticos, sigue habiendo una carga considerable de la enfermedad entre los grupos más jóvenes y de mayor edad, así como en las regiones con bajo desarrollo económico. En nuestra opinión, aunque una vacuna sería una opción eficaz para controlar la disentería bacilar a corto y medio plazo, todo control a largo plazo exigirá probablemente mejoras del abastecimiento de agua, el saneamiento y la higiene.

OBJECTIF: L'étude visait à déterminer la charge de dysenterie bacillaire en Chine, les variations interrégionales, les tendances de la morbidité et de la mortalité, les agents étiologiques bactériens et les schémas de résistance aux antimicrobiens. MÉTHODES: Les statistiques publiques et les documents médicaux pertinents publiés de 1991 à 2000 ont été extraits et pris en compte dans l'étude. On a également recueilli des données auprès d'un hôpital général de chacune des six provinces considérées et du district de Jin an à Shanghai, ces hôpitaux étant représentatifs de six régions géographiques et d'une ville moderne. RÉSULTATS: En 2000, 0,8 à 1,7 million d'épisodes de dysenterie bacillaire on été enregistrés, dont 0,5 à 0,7 million ont été traités dans des établissements de soins et 150 000 à 200 000 ont donné lieu à des hospitalisations. Les taux de morbidité et de mortalité les plus élevés ont été relevés parmi les classes d'âge correspondant aux plus jeunes et aux plus âgés. La dysenterie bacillaire a atteint un pic au cours des mois d'été. Le principal agent étiologique était Shigella flexneri (86 %) et le sérotype prédominant de S. flexneri était le sérotype 2a (80 %). De 74 % à 80 % des isolements de Shigella étaient sensibles aux quinolones fluorés. CONCLUSION: Malgré une baisse considérable de la morbidité et de la mortalité dues à la dysenterie bacillaire en Chine au cours de la dernière décennie, imputable à l'amélioration de l'accès à des soins de santé et à des antibiotiques à des prix abordables, une importante charge de morbidité subsiste chez les classes d'âge extrêmes et dans les régions faiblement développées sur le plan économique. Si un vaccin constituerait un moyen efficace à court et à moyen terme pour lutter contre la dysenterie bacillaire, il est probable que la lutte à long terme contre cette maladie exige une amélioration de l'approvisionnement en eau, des installations d'assainissement et de l'hygiène.
