Methods: 108 patients diagnosed with prehypertension in our hospital were divided into a control group and an experimental group. The control group was not given management measures, while the experimental group was given health management. The incidence of hypertension and cognition level of hypertension knowledge were compared between the two groups after management. Results: The incidence of hypertension in the experimental group was 7.41% lower than that in the control group 29.63%. The cognitive level of hypertension in the patients (66.54 ± 1.25) was significantly higher than that in the patients without health management (41.45 ± 2.45), and P < 0.05;Conclusion: For patients with prehypertension, the implementation of health management is helpful to improve their cognition of hypertension, master related prevention knowledge, and reduce the incidence of hypertension.展开更多

The study aimed to examine the lives of mothers raising children with autism spectrum disorder (ASD) and investigate their sources of support. Method: We conducted a qualitative inductive study using semi-structured interviews to identify characteristics of the lives that mothers have created. Results: Semi-structured interviews were conducted with 11 mothers having children with ASD. The analysis comprised three stages of coding and yielded eight categories. The lives of these mothers contained three themes: preoccupation with parenting children with ASD and their siblings;evolving mother;and using social resources. Mothers engaged in “assessing the characteristics, growth, and changes in the child with ASD”, had a “preoccupation with parenting children with ASD”, and were “thinking about the future of the child with ASD”, and “having goals and plans for parenting” while having “consideration toward the child’s siblings”. During this process, mothers experienced “changes in perspective or approach” and created lifestyles while “receiving help from people around them” and engaged in the “use of social resources”. Conclusions: To avoid becoming preoccupied with parenting and being burdened by their lifestyle, mothers require social support to monitor their perceptions. Furthermore, the utilization of social resources requires the supporting individuals to understand the characteristics of children with ASD, provide appropriate information, and assist in decision-making.展开更多

However, no study has been reported on the effect of these movements on the cerebral cortex. In this study, using functional near infrared spectroscopy(f NIRS), we attempted to investigate cortical activation generated during bilateral arm raising movements. Ten normal subjects were recruited for this study. f NIRS was performed using an f NIRS system with 49 channels. Bilateral arm raising movements were performed in sitting position at the rate of 0.5 Hz. We measured values of oxyhemoglobin and total hemoglobin in five regions of interest: the primary sensorimotor cortex, premotor cortex, supplementary motor area, prefrontal cortex, and posterior parietal cortex. During performance of bilateral arm raising movements, oxyhemoglobin and total hemoglobin values in the primary sensorimotor cortex, premotor cortex, supplementary motor area, and prefrontal cortex were similar, but higher in these regions than those in the prefrontal cortex. We observed activation of the arm somatotopic areas of the primary sensorimotor cortex and premotor cortex in both hemispheres during bilateral arm raising movements. According to this result, bilateral arm raising movements appeared to induce large-scale neuronal activation and therefore arm raising movements would be good exercise for recovery of brain functions.展开更多

They were divided into 2 groups: a SLR group (group S) and a control group (group C) randomly, with each group having 20 animals. All rabbits were subjected to total laminectomy in the site of S1. Every 5 rabbits in each group selected randomly were killed at the 1st, 2nd, 4th, and 8th week after the surgery. Segments of spines from L,7 to S2 were removed en bloc. After gross evaluation, specimens were sliced up. The slices were stained by HE and Masson's trichrome methods respectively for histological examination. Our results showed that formation process of scar in group S was retarded as compared with that of group C at the time of the 2nd-week, but there was no statistical difference between groups in the adhesion degree (P≥0.05). At the 4th and 8th week, the epidural fibrosis of group S was more serious than that of group C. Since the 2nd-week, the area of scar in group S was larger than that of group C. The number of fibroblasts and inflammatory cells in group S were larger than those of group C at early stage. But in later stage, there was no statistical significance between the two groups. It is concluded that SLR movement after laminectomy may promote the formation of epidural fibrosis and retard the maturity of scar. SLR movement can also aggravate scar adhesion.展开更多

文摘The study of thermal characteristics during startup is one of the most important aspects for safety analysis of supercritical water-cooled reactor(SCWR).According to the given sliding pressure mode of SCWR,thermal analysis on temperature-raising phase and power-raising phase of startup are carried out.Considering the radial heterogeneity of power distribution,thermal characteristics for different assemblies during startup are also put forward.The results show that,during temperature-raising phase with core power increased only,the temperature of moderator,coolant and fuel cladding in inner assemblies are increased with little amplitude.During power-raising phase with core power and feed-water flow rate increased,the coolant temperature keeps unchanged,but the moderator temperature is decreased.With a greater variation of power,fuel cladding temperature shows a greater increase.Furthermore,considering the uneven distribution of radial power,thermo-hydraulic characteristics with uneven cladding temperature distribution shows a certain horizontal heterogeneity for different fuel assemblies,which becomes serious as flow rate and power increase.By adjusting flow rate distribution in different fuel assemblies or changing power setting during startup,the cladding temperature difference could be effectively reduced,which provides a certain reference for startup optimization of SCWR.

文摘To determine the effect of straight-leg-raising (SLR) movement on epidural fibrosis after laminectomy, 40 adult New Zealand rabbits were selected as laminectomy models in the study. They were divided into 2 groups: a SLR group (group S) and a control group (group C) randomly, with each group having 20 animals. All rabbits were subjected to total laminectomy in the site of S1. Every 5 rabbits in each group selected randomly were killed at the 1st, 2nd, 4th, and 8th week after the surgery. Segments of spines from L,7 to S2 were removed en bloc. After gross evaluation, specimens were sliced up. The slices were stained by HE and Masson's trichrome methods respectively for histological examination. Our results showed that formation process of scar in group S was retarded as compared with that of group C at the time of the 2nd-week, but there was no statistical difference between groups in the adhesion degree (P≥0.05). At the 4th and 8th week, the epidural fibrosis of group S was more serious than that of group C. Since the 2nd-week, the area of scar in group S was larger than that of group C. The number of fibroblasts and inflammatory cells in group S were larger than those of group C at early stage. But in later stage, there was no statistical significance between the two groups. It is concluded that SLR movement after laminectomy may promote the formation of epidural fibrosis and retard the maturity of scar. SLR movement can also aggravate scar adhesion.

文摘[Objective] The aim was to o research the control effect to Varroa destructor and Tropilaeplaps clareae whit new raising management methods, and reduce the pollution caused by drug treatment of bee. [ Metkod] We took the method that was replace the hive and comb on test col- onies with the comb Formalin soaking liquid used three days after the dry and sterilization in advance with the hive. The test groups were 10 colonies randomly selected from the disinfected comb in the breeding. This was the first kind of method. The control groups were 10 colonies randomly se- lected by the conventional breeding management methods. From January 20th, statistic analysis on parasitic situation of bees once every month be- tween the two methods, and take corresponding measures to prevent and control the varroa mite according to the varroa mite parasitic number in time, then the control effect of mite between the two methods were compared with. [ Result] The results showed that the first method was better than the second one in V. destructor, the control time of T. clareae delayed about one month [ Conclusion] Good breeding method could restrain I V. destructor and T. clareae parasitism, speeded up the colony development, and reduced the pollution of chemical drugs on bee products, regar- dod as a kind good method of controlling bee mites to make use of the feeding and management technology.
文摘This paper expounds the application of machine vision theory, composition and technology in the sow breeding process monitoring, auxiliary judgment, and growth of young monitoring. It also points out the problems and deficiency in the application of machine vision technology, and discusses the development trends and prospects of the machine vision technology in agricultural engineering. The application of machine vision is a process in which dynamic original image from the sows estrus is collected with a CCD camera, and then black and white ash three binarization image in adjournments of the threshold value is made by using image acquisition card, through the median filtering and gray processing. The practitioners can extract respective image information from the sow estrus, pregnancy and birth delivery. Applying the computer vision system in the sow farm effectively enhances the practitioners’ objectivity and precision in their efforts to assess the whole process of sow birth delivery.

文摘● From the start of nationwide fund raising for power construction after the Document No. 111 issuedby the State Council in 1987 to the start of power institutional reform early this century, duringthese 20 years, China's power industry developed rapidly and made great achievements.● The 20- year history of raising funds for power construction indicates that this policy is very wiseand correct. It aroused enthusiasm from both the central government and the local government,and contributed greatly to the historic leap of installed capacity from 100 GWin 1987 to 600 GWin 2006.● The practice of 20 years can be summarized as follows. Adhering to power institutional reform wasa strong impetus to promote the development of power industry; "breaking up monopoly and intro-ducing competition" was the only way for power institutional reform ; raising funds for powerconstruction promoted the power institutional reform ; while separating grid and plants propelledthe marketization of generation side, so was the fundamental reform of the management system inpower industry.
