In order to find applicable approaches to solve this problem, the current situations of the Chinese higher education reform and the resulted rapid growth of student numbers whereby the requirement of lodgings is greatly increased are discussed. It is elucidated that in providing enough accommodations for staff and students, Chinese universities are confronted with difficulties including demand too big, lack of funding support, time limitation and incapability in both project management and facilities management. Industrialized building approach is demonstrated to be a desirable access to build large quantities of accommodations of good quality in limited time, and Private Financial Initiative (PFI) appears to be a prosperous solution to the fund shortage. Regarding project and facilities management, qualified professionals are available by either employing exterior consultants or training related staff of universities for such occupations.展开更多

METHODS： A prospective, non-randomized, case-control study was performed from September to October 2016. Eighty-three children with myopia were divided into two groups. One group was treated with the rigid contact lens for overnight Ortho-k, and the other was treated with single-vision spectacle lens（SVL）. Accommodation function were assessed by accommodative amplitude（AA）, accommodative sensitivity（AS）, accommodative lag（Lag）, negative relative accommodation（NRA）, and positive relative accommodation（PRA） before and 1, 3, 6 and 12 mo after treated. RESULTS： Totally 72 myopic children were finished the follow-up： 37 in Ortho-k group and 35 in SVL group. Wearing time had a significant effect on AA, AS, Lag, and NRA of myopic children in two groups（all P〈0.05）. Meanwhile, there was an interaction effect between wearing time and wearing types（FAA=5.3, FAS=45.5, FLag=7.0, FNRA=3.7, all P〈0.05）. However, the between-group difference of AA（F=0.1）, AS（F=3.2）, Lag（F=1.1）, NRA（F=0.3）, and PRA（F=0.1） showed no significance. AA, AS, NRA, Lag and PRA were improved significantly in Ortho-k group within 1 to 6 mo after wearing. CONCLUSION： Wearing Ortho-k can improve the accommodation function of myopic children, which might be one of the mechanisms for myopia control.展开更多

The term gastric accommodation has at least three different meanings： The accommodation process, the accommodation reflex, and the accommodation response. The gastric accommodation process is a complex phenomenon that describes how the size of the gastric compartment changes in response to a meal. The electronic barostat is considered the gold standard in assessing gastric accommodation. Imaging methods, including MRI, SPECT, and ultrasonography may also be used, particularly in patients who are stress-responsive, e.g. functional dyspepsia patients, as a non-invasive and less stress-inducing method is favourable. Ultrasonography satisfies these criteria as it does not by itself distort the physiological response in stress-responsive individuals.展开更多

METHODS: Between April 2011 and March 2012, 45 patients with FD and 27 healthy volunteers were enrolled in this study. Two-dimensional ultrasound (2DUS) and 3-dimensional ultrasound (3DUS) were performed sequentially to measure proximal gastric area (PGA), maximal proximal gastric diameter (MPGD), and proximal gastric volume (PGV). These values were measured separately in the two groups every other 5 min for a duration of 25 min after the beginning of ingestion of a test meal. Air pocket grading was done separately for images of 2DUS and blocks of 3DUS obtained at five scanning time points. RESULTS: Both PGA and PGV of patients were significantly smaller than healthy controls (P = 0.000 and 0.002, respectively). Comparing the two parameters between the groups at each time point, the differences were also statistically significant (P = 0.000-0.013), except at 10 min for the PGV (P = 0.077). However, no overall difference was found between the groups in the MPGD measurements (P = 0.114), though it was statistically significant at a 20-minute examination point (P = 0.026). A total of 360 sets or blocks of images were obtained for both 2DUS and 3DUS. For the images analyzed by 2DUS, none were excluded because of gastric gas, and 50 (13.9%) and 310 (86.1%) sets were determined as air pockets grades 1 and 2, respectively. For the images analyzed by 3DUS, 23 (6.4%) blocks were excluded from the measurement due to presence of a large fundus air pocket (grade 3); fifty (13.9%) and 287 (79.7%) blocks were also graded as 1 and 2, respectively. CONCLUSION: Measurement of both PGA and PGV by 2DUS and 3DUS could be useful for assessment of the proximal gastric accommodation.展开更多

文摘The selection of twin variants plays a critical role in shaping the deformation texture and mechanical properties of magnesium alloys that are limited by slip systems and diverse twinning modes.In this study,we investigated the twin variant selection and the effect of twinning activity on the strain hardening of a hot-rolled AZ31 magnesium alloy by quasi-in-situ EBSD.Moreover,the Schmid factors and the displacement gradient tensors were computed to evaluate the activation of twin variants.The results reveal that the yield strength increased progressively after each deformation step,driven by grain subdivision and texture hardening induced by extension{1012}twinning and the Basinski effect at large strains.The nucleation and growth of the{1012}twins occurred either sequentially or simultaneously during the plastic deformation.At low plastic strains,the activation of most twin variants followed the high Schmid factor criterion while the other twin variants with lower Schmid factors were activated due to the interactions with preexisting twins characterized by high misorientation angles(around 60°).Additionally,this non-Schmid factor scenario was also attributed to low coordinated strain requirements from neighboring grains,showing the critical role of local deformation accommodation in the twinning process.These findings advance the fundamental understanding of the twin variant selection and its implications for the microstructure-property relationship in magnesium alloys for structural applications.

文摘Patients with liver cirrhosis exhibit several features of gut dysfunction which may contribute to the development of cirrhosis complications as well as have an impact on nutritional status and health-related quality of life.Gastrointestinal symptoms are common in cirrhosis and their pathophysiology probably involves factors related to liver disease severity,psychological distress,and gut dysfunction(e.g.,increased gastric sensitivity to distension and delayed gut transit).They may lead to reduced food intake and,thus,may contribute to the nutritional status deterioration in cirrhotic patients.Although tense ascites appears to have a negative impact on meal-induced accommodation of the stomach,published data on gastric accommodation in cirrhotics without significant ascites are not unanimous.Gastric emptying and small bowel transit have generally been shown to be prolonged.This may be related to disturbances in postprandial glucose,insulin,and ghrelin levels,which,in turn,appear to be associated to insulin resistance,a common finding in cirrhosis.Furthermore,small bowel manometry disturbances and delayed gut transit may be associated with the development of small bowel bacterial overgrowth.Finally,several studies have reported intestinal barrier dysfunction in patients with cirrhosis(especially those with portal hypertension),which is related to bacterial translocation and permeation of intestinal bacterial products,e.g.,endo-toxin and bacterial DNA,thus potentially being involved in the pathogenesis of complications of liver cirrhosis.

文摘AIM： To study effects of orthokeratology（Ortho-k） on accommodation function in myopic children. METHODS： A prospective, non-randomized, case-control study was performed from September to October 2016. Eighty-three children with myopia were divided into two groups. One group was treated with the rigid contact lens for overnight Ortho-k, and the other was treated with single-vision spectacle lens（SVL）. Accommodation function were assessed by accommodative amplitude（AA）, accommodative sensitivity（AS）, accommodative lag（Lag）, negative relative accommodation（NRA）, and positive relative accommodation（PRA） before and 1, 3, 6 and 12 mo after treated. RESULTS： Totally 72 myopic children were finished the follow-up： 37 in Ortho-k group and 35 in SVL group. Wearing time had a significant effect on AA, AS, Lag, and NRA of myopic children in two groups（all P〈0.05）. Meanwhile, there was an interaction effect between wearing time and wearing types（FAA=5.3, FAS=45.5, FLag=7.0, FNRA=3.7, all P〈0.05）. However, the between-group difference of AA（F=0.1）, AS（F=3.2）, Lag（F=1.1）, NRA（F=0.3）, and PRA（F=0.1） showed no significance. AA, AS, NRA, Lag and PRA were improved significantly in Ortho-k group within 1 to 6 mo after wearing. CONCLUSION： Wearing Ortho-k can improve the accommodation function of myopic children, which might be one of the mechanisms for myopia control.
文摘Gastric accommodation is important for the understanding of the pathophysiology in functional dyspepsia and is also relevant for symptom generation in other disorders. The term gastric accommodation has at least three different meanings： The accommodation process, the accommodation reflex, and the accommodation response. The gastric accommodation process is a complex phenomenon that describes how the size of the gastric compartment changes in response to a meal. The electronic barostat is considered the gold standard in assessing gastric accommodation. Imaging methods, including MRI, SPECT, and ultrasonography may also be used, particularly in patients who are stress-responsive, e.g. functional dyspepsia patients, as a non-invasive and less stress-inducing method is favourable. Ultrasonography satisfies these criteria as it does not by itself distort the physiological response in stress-responsive individuals.

文摘AIM: To assess the value of ultrasonography (US) in evaluation of proximal gastric accommodation disorder in patients with functional dyspepsia (FD). METHODS: Between April 2011 and March 2012, 45 patients with FD and 27 healthy volunteers were enrolled in this study. Two-dimensional ultrasound (2DUS) and 3-dimensional ultrasound (3DUS) were performed sequentially to measure proximal gastric area (PGA), maximal proximal gastric diameter (MPGD), and proximal gastric volume (PGV). These values were measured separately in the two groups every other 5 min for a duration of 25 min after the beginning of ingestion of a test meal. Air pocket grading was done separately for images of 2DUS and blocks of 3DUS obtained at five scanning time points. RESULTS: Both PGA and PGV of patients were significantly smaller than healthy controls (P = 0.000 and 0.002, respectively). Comparing the two parameters between the groups at each time point, the differences were also statistically significant (P = 0.000-0.013), except at 10 min for the PGV (P = 0.077). However, no overall difference was found between the groups in the MPGD measurements (P = 0.114), though it was statistically significant at a 20-minute examination point (P = 0.026). A total of 360 sets or blocks of images were obtained for both 2DUS and 3DUS. For the images analyzed by 2DUS, none were excluded because of gastric gas, and 50 (13.9%) and 310 (86.1%) sets were determined as air pockets grades 1 and 2, respectively. For the images analyzed by 3DUS, 23 (6.4%) blocks were excluded from the measurement due to presence of a large fundus air pocket (grade 3); fifty (13.9%) and 287 (79.7%) blocks were also graded as 1 and 2, respectively. CONCLUSION: Measurement of both PGA and PGV by 2DUS and 3DUS could be useful for assessment of the proximal gastric accommodation.

文摘AIM:To explore the photopic pupil size behavior in myopic children undergoing overnight orthokeratology(ortho-k)over 1-year period and its effects on the axial elongation.METHODS:A total of 202 Chinese myopic children were enrolled in this prospective clinical trial.Ninetyfive subjects in ortho-k group and eighty-eight subjects in spectacle group completed the 1-year study.Axial length(AL)was measured before enrollment and every 6mo after the start of ortho-k.The photopic pupil diameter(PPD)was determined using the Pentacam AXL and measured in an examination room with lighting of 300-310 Lx.Stepwise multiple linear regression analysis was used to identify variables contribution to axial elongation.RESULTS:Compared with spectacle group,the average 1-year axial elongation was significantly slower in the ortho-k group(0.25±0.27 vs 0.44±0.23 mm,P<0.0001).In ortho-k group,PPDs significantly decreased from 4.21±0.62 mm to 3.94±0.53 mm after 1mo of lens wear(P=0.001,Bonferroni correction)and the change lasts for 3-month visit.No significantly change during the other follow-up visits was found(P>0.05,Bonferroni correction).The 4.81 mm PPD may be a possible cutoff point in the ortho-k group.Subjects with PPD below or equal to 4.81 mm tended to have smaller axial elongation compared to subjects with PPD above 4.81 mm after 1-year period(t=-3.09,P=0.003).In ortho-k group,univariate analyses indicated that those with older age,greater degree of myopia,longer AL,smaller baseline PPD(PPDbaseline)experienced a smaller change in AL.In multivariate analyses,older age,greater AL and smaller PPDbaseline were associated with smaller increases in AL.In spectacle group,PPD tended to be stable(P>0.05,Bonferroni correction)and did not affect axial growth.CONCLUSION:PPDs experience significantly decreases at 1-month and 3-month ortho-k treatment.Children with smaller PPD tend to experience slower axial elongation and may benefit more from ortho-k.
