In the current study, we scrutinized the effect of sevoflurane and halothane on cognitive and immune function in young rats. The rats were divided into following groups: sevoflurane, halothane and sevoflurane + halothane groups, respectively. The rats were regularly treated with the pre-determined treatment. We also scrutinized the serum proinflammatory cytokines including IL-10, IL-4 and IL-2; brain level IL-1β; hippocampal neuronal apoptosis concentration were estimated. The water maze test was performed in rats for the estimation of cognitive ability. During the water maze test, on the 1st day the sevoflurane group showed the latency; sevoflurane and sevoflurane + halothane group demonstrated the declined latency gradually as compared to the control group rats after the 3 days. The latency of the control, halothane, sevoflurane + halothane group rats showed the reduced latency and also showed the reduced crossing circle times. The hippocampal neuron apoptosis was significantly increased in halothane and sevoflurane + halothane group as compared to control group rats, respectively. Control group rats demonstrated the increased neuron apoptosis. The proinflammatory cytokines including IL-10 and IL-4 was significantly higher in sevoflurane, halothane and sevoflurane + halothane group rats after anesthesia and the whole brain IL-1β was significantly decrease in the sevoflurane, halothane and sevoflurane + halothane as compared to control group. Sevoflurane can inhibit the anesthesia effect of halothane on the immune and cognitive function of rats. 相似文献

Although the current glucocorticoids (GCs) treatment for systemic lupus erythematosus (SLE) is effective to a certain extent, the difference in therapeutic effect between patients is still a widespread problem. Some patients can have repeated attacks that greatly diminish their quality of life. This study was conducted to investigate the relationship between HSP90AA2 polymorphisms and disease susceptibility, GCs efficacy and health-related quality of life (HRQoL) in Chinese SLE patients. A case–control study was performed in 470 SLE patients and 470 normal controls. Then, 444 patients in the case group were followed up for 12 weeks to observe efficacy of GCs and improvement of HRQoL. Two single nucleotide polymorphisms (SNPs) of HSP90AA2 were selected for genotyping: rs1826330 and rs6484340. HRQoL was assessed using the SF-36 questionnaire. The minor T allele of rs1826330 and the TT haplotype formed by rs1826330 and rs6484340 showed associations with decreased SLE risk (T allele: PBH?=?0.022; TT haplotype: PBH?=?0.033). A significant association between rs6484340 and improvement of HRQoL was revealed in the follow-up study. Five subscales of SF-36 were appeared to be influenced by rs6484340: total score of SF-36 (additive model: PBH?=?0.026), physical function (additive model: PBH?=?0.026), role-physical (recessive model: PBH?=?0.041), mental health (dominant model: PBH?=?0.047), and physical component summary (additive model: PBH?=?0.026). No statistical significance was found between HSP90AA2 gene polymorphisms and GCs efficacy. These results revealed a genetic association between HSP90AA2 and SLE. Remarkably, HSP90AA2 has an impact on the improvement of HRQoL in Chinese population with SLE. 相似文献

Examinations were made on the morphology of caryopses of 324 grass species representing over 109 genera and 31 tribes. The evolutionary tendency of the important characteristics and the relation with distribution areas and habitats are discussed. According to the
shape of caryopses, the morphology of ventral faces and hilum, the proportion of embryos to
caryopses in size, the existence or absence of the top fine hairs, the persistence or shedding of
styles, the size of fruits and especially the outline of the middle cross section, etc., the caryopses
may be divided into three major types and seven subtypes: Bambusoid (including True Bambusoid,
Arundinoid, Oryzoid, Stipoid), Panicoid (including True Panicoid, Eragrostoid) and Pooid
(including the Subtype Pooid only). In this study, the different types of caryopses are found to
be correlated with the characteristics of embryos, seedlings, habits and chromosomes, and on
these grounds, the genera of the Gramineae are grouped into seven corresponding subfamilies:
Bambusoideae, Oryzoideae, Arundinoideae, Stipoideae, Eragrostoideae, Panicoideae and Pooideae. 相似文献

The classification and the relationships among the genera of Chinese
Triticeae were studied based on morphological characters with reference to geographical distribution and habitat conditions.
The spike of Triticeae might have been derived from a panicled inflorescence like
that in the Bromeae through a racemose inflorescence like the one in the Brachypodieae. There might be three evolutionary lines in the tribe.
1. Pedicels of the panicled inflorescence have become short and bracts decreased
in size, which has resulted in a panicled spike with indefinite spikelets or false solitary
spikelets at each node of rachis. The middle ribes of both glumes and lemmas and rachilla are not in a single plane. 2. A simple spike with usual solitary spikelets at each
node of rachis has been derived from the raceme. The middle ribe of both glumes and
lemmas and rachilla are in a single plane. 3. A cymose spike with 3-spikelets at each
node of rachis has evolved from the cymose panicle. The glume on the central spikelet
is behind the lemma, while those on the lateral spikelets are on lateral sides of the lemmas.
From what we have described above Triticeae may be divided into three subtribes:
Elyminae, Triticinae and Hordeinae. Then according to the morphological characters
of glume, lemma and other organs as well as the habitats and distribution, the native and
introduced triticeous plants are classified into 13 genera (Leymus, Elymus, Roegneria,
Elytrigia, Aegilops, Triticum, Agropyron, Eremopyrum, Secale, Haynaldia, Psathyrostachys, Hordeum and Hystrix) and their relationships are also discussed meanwhile. 相似文献
