The general procedure in designing a grand style timber structure is to start with the grade that defines the basic module (dou kou); next comes with the number of bracket set (cuan), the number of longitudinal bays and the number of purlins which affect its plan and cross section; thirdly choose a roof type that determines its longitudinal section and the facade as well. A series of formulae are conducted to help depict the layout, cross sectional roof curvature and special longitudinal treatments in 4 sloped and 9 spined roofs respectively.展开更多

The herbal medicine Qing Dai has traditionally been used in Chinese medicine to treat UC patients, but there is a lack of published data on the efficacy of Qing Dai in UC treatment. We report several cases of patients with intractable UC who take Qing Dai in a retrospective observational study. Furthermore, we explore the mechanisms of action of Qing Dai. Nine patients with active UC who received conventional medications but wished to receive Qing Dai as an alternative medication were included in our analysis. The UC severity level was determined based on the clinical activity index (CAI). Additionally, 5 of the 9 patients were endoscopically evaluated according to the Matts grading system. Each patient received 2 g/d of Qing Dai orally and continued taking other medications for UC as prescribed. Electron spin resonance was applied to explore the mechanisms of action of Qing Dai. After 4 mo of treatment with Qing Dai, the CAI score decreased from 8.3 ± 2.4 to 2.4 ± 3.4 (mean ± SD; P < 0.001). Similarly, the endoscopic Matts grade decreased from 3.4 ± 0.5 to 2.2 ± 0.8 (P = 0.02). Six of 7 patients who were on prednisolone upon enrollment in the study were able to discontinue this corticosteroid. Electron spin resonance revealed that Qing Dai possesses strong hydroxyl radical scavenging activity. Qing Dai showed significant clinical and endoscopic efficacy in patients who failed to respond to conventional medications. Scavenging of hydroxyl radicals appears to be a potential mechanism through which Qing Dai acts, but the significance of the scavenging ability of Qing Dai with respect to the anti-inflammatory effect in UC patients warrants further investigation.展开更多

Our preliminary studies confirmed that Qing＇e formula （QEF） could effectively increase serum 25 hy- droxyvitamin D concentration in patients with postmenopausal osteoporosis （PMOP）, but the effect of supplementation with QEF on serum sclerostin is unknown. This study investigated the effects of sup- plementation of QEF on serum sclerostin levels in patients with PMOP. Totally 120 outpatients and in- patients with PMOP treated in our hospital between January and October 2012 were randomly divided into QEF＋calcium group, alfacalcidol＋calcium group, and placebo＋calcium group （n=40 each）, with a follow-up period of 2 years. The serum levels of sclerostin, 25 hydroxyvitamin D, and bone turnover markers （β-CTX, N-MID and T-PINP） at baseline and at the 6th month, 1st year, 1.5th year, and 2nd year after treatment were measured. The results showed that the levels of circulating sclerostin were in- creased significantly at the 6th month after treatment in QEF＋calcium group and alfacalcidol＋calcium group as compared with placebo＋calcium group （P〈0.05）, but there was no significant difference be- tween the former two groups （P〉0.05）. The levels of β-CTX, N-MID and T-PINP in serum were de- creased in both QEF＋calcium group and alfacalcidol＋calcium group at the 6th month after treatment, without significant difference between the two groups （P〉0.05）. BUt the levels were significantly lower than that in placebo＋calcium group （P〈0.05）. These results suggest that the mechanism by which QEF modulates bone metabolism in patients with PMOP might be related with the effect of QEF in increas- ing sclerostin expression. Our findings provide a scientific rationale for using QEF as an effective drug to prevent bone loss in PMOP.展开更多

This article attempts to extract characteristics of the weathering pits by descriptive statistics and orientation rose diagrams, investigate the multi-phase evolution by the modified gnamma morphological analysis （GMA） method, and shed new light on the possible genesis and the influencing factors. Following the modified GMA method, weathering pits in Qing Mountain have been divided into six groups and compared with analogous sites to deduce their approximate age, which might be no older than 30 ka B.P., and explore the possibility that the multi-phase evolution of weathering pits may arise from responses to climate change. In consequence, we suggest that the combination of weathering, especially salt weathering, and wind erosion, both of which are closely related to climatic variation, take the main responsibility for the formation and development of weathering pits in Qing Mountain.展开更多

Methods： Ten patients with chronic hemorrhagic radiation proctitis between January 2005 to January 2008 were treated with Qing Dai. Qing Dai was administered orally at a dose of 1.5 g, bid for 5 consecutive days, every 2 weeks for two courses. Patients were followed up every 3 months. The clinical response and side-effects were evaluated. Results： Six patients showed improvement of rectal bleeding to grade 0-1 after 1 course of Qing Dai therapy. Four patients had reduced rectal bleeding to grade 0-1 after 2 courses of the therapy. The median follow-up time was 10 months （range： 6-24）. During the follow-up period, 1 patient experienced recurrent rectal bleeding and was managed with topical formalin dabbing, which controlled the symptom. No treatment toxicity was observed. Conclusion： Qing Dai may be a safe and effective treatment for chronic hemorrhagic radiation proctitis.展开更多

Qing Dai showed significant clinical and endoscopic efficacy in patients who failed to respond to conventional medications. Scavenging of hydroxyl radicals appears to be a potential mechanism through which Qing Dai acts, but the significance of the scavenging ability of Qing Dai with respect to the anti-inflammatory effect in UC patients warrants further investigation.
文摘AIM To observe the changes in oxygen free radical (OFR) and the curative effect of traditional Chinese medicine 'Qing Yi Tang' in acute necrotizing pancreatitis (ANP).METHODS After induction of ANP by injection of sodium taurocholate into pancreatic duct, 16 dogs were randomly divided into control group and Chinese medicine group. Serum amylase, SOD and MDA were determined on postoperative day 1, 2, 4 and 7. The animals were sacrificed on day 7. SOD and MDA in organs were determined, and pathological changes in pancreas were observed.RESULTS As compared with control group, the serum level of amylase (734U/L vs 2783U/L) and MDA (7.8nmol/ml vs 14.8nmol/ml) in Chinese medicine group were decreased on day 7 (P＜0.05), while SOD increased significantly (281nU/ml vs 55nU/ml, P＜0.01), and similar changes occurred in MDA and SOD in organs, especially in the pancreas; the pathological changes in the pancreas were alleviated as well.CONCLUSION 'Qing Yi Tang' is effective in clearing OFRs and alleviating pathological changes in ANP.

文摘Summary： Serum sclerostin is positively associated with serum 25 hydroxyvitamin D concentration. Our preliminary studies confirmed that Qing＇e formula （QEF） could effectively increase serum 25 hy- droxyvitamin D concentration in patients with postmenopausal osteoporosis （PMOP）, but the effect of supplementation with QEF on serum sclerostin is unknown. This study investigated the effects of sup- plementation of QEF on serum sclerostin levels in patients with PMOP. Totally 120 outpatients and in- patients with PMOP treated in our hospital between January and October 2012 were randomly divided into QEF＋calcium group, alfacalcidol＋calcium group, and placebo＋calcium group （n=40 each）, with a follow-up period of 2 years. The serum levels of sclerostin, 25 hydroxyvitamin D, and bone turnover markers （β-CTX, N-MID and T-PINP） at baseline and at the 6th month, 1st year, 1.5th year, and 2nd year after treatment were measured. The results showed that the levels of circulating sclerostin were in- creased significantly at the 6th month after treatment in QEF＋calcium group and alfacalcidol＋calcium group as compared with placebo＋calcium group （P〈0.05）, but there was no significant difference be- tween the former two groups （P〉0.05）. The levels of β-CTX, N-MID and T-PINP in serum were de- creased in both QEF＋calcium group and alfacalcidol＋calcium group at the 6th month after treatment, without significant difference between the two groups （P〉0.05）. BUt the levels were significantly lower than that in placebo＋calcium group （P〈0.05）. These results suggest that the mechanism by which QEF modulates bone metabolism in patients with PMOP might be related with the effect of QEF in increas- ing sclerostin expression. Our findings provide a scientific rationale for using QEF as an effective drug to prevent bone loss in PMOP.

文摘The anti-tumor effect of anti-PD-1 antibody has long been shown to be strongly related to the tumor immune microenvironment(TIME).This study aimed to mechanistically assess whether Chang Wei Qing(CWQ)Decoction can enhance the anti-tumor effect of PD-1 inhibitor therapy.PD-1 inhibitor therapy showed the significant anti-tumor effect in patients with mismatch repairdeficient/microsatellite instability-high(dMMR/MSI-H)colorectal cancer(CRC),rather than those with mismatch repairproficient/microsatellite stable(pMMR/MSS)CRC.Hence,immunofluorescence double-label staining was utilized to explore the difference in the TIME between dMMR/MSI-H and pMMR/MSS CRC patients.Flow cytometry was used to analyze T-lymphocytes in tumors from mice.Western blot was used to measure the expression of PD-L1 protein in mouse tumors.The intestinal mucosal barrier of mice was evaluated by hematoxylin-eosin staining and immunohistochemistry.16S rRNA-gene sequencing was used to examine the structure of the gut microbiota in mice.Subsequently,Spearman’s correlation analysis was used to analyze the relationship between the gut microbiota and tumor-infiltrating T-lymphocytes.The results showed that dMMR/MSI-H CRC patients had more CD8+T cells and higher expression of PD-1 and PD-L1 proteins.In vivo,CWQ enhanced the anti-tumor effect of anti-PD-1 antibody and increased the infiltration of CD8+and PD-1+CD8+T cells in tumors.Additionally,the combination of CWQ with anti-PD-1 antibody resulted in lower inflammation in the intestinal mucosa than that induced by anti-PD-1 antibody alone.CWQ and anti-PD-1 antibody co-treatment upregulated PD-L1 protein and reduced the abundance of Bacteroides in the gut microbiota but increased the abundance of Akkermansia,Firmicutes,and Actinobacteria.Additionally,the proportion of infiltrated CD8+PD-1+,CD8+,and CD3+T cells were found to be positively correlated with the abundance of Akkermansia.Accordingly,CWQ may modulate the TIME by modifying the gut microbiota and consequently enhance the anti-tumor effect of PD-1 inhibitor therapy.

文摘A total of 80 weathering pits （gnammas）, located on granite surfaces of Qing Mountain （青山）, Hexigten （克什克腾） Global Geopark, Inner Mongolia, were identified and measured in terms of dimensional and orientational features. This article attempts to extract characteristics of the weathering pits by descriptive statistics and orientation rose diagrams, investigate the multi-phase evolution by the modified gnamma morphological analysis （GMA） method, and shed new light on the possible genesis and the influencing factors. Following the modified GMA method, weathering pits in Qing Mountain have been divided into six groups and compared with analogous sites to deduce their approximate age, which might be no older than 30 ka B.P., and explore the possibility that the multi-phase evolution of weathering pits may arise from responses to climate change. In consequence, we suggest that the combination of weathering, especially salt weathering, and wind erosion, both of which are closely related to climatic variation, take the main responsibility for the formation and development of weathering pits in Qing Mountain.
文摘The determination of channel evolutions and the causes is important for reconstructing the evolutionary history of river landforms.This study aimed to elucidate the downstream channel evolution of the Yuan River in Hunan Province,China,during the Qing Dynasty via Landsat 8 satellite image data and relevant literature.The objective was to establish the modes of channel evolution and discuss the significance of historical climate change.The downstream paleochannel of the Yuan River was identified in the Late Ming Dynasty and Early Qing Dynasty(1600–1644 AD),the Kangxi-Qianlong periods of the Qing Dynasty(1661–1796 AD),the Late Qing Dynasty(1840–1912 AD),and the World War II(1939–1945 AD),and three main modes of river evolution were determined.Using remote sensing data and the ancient literature,the evolution characteristics of the paleochannel in the Lower Yuan River were analyzed and its distribution across historical periods was comprehensively revealed.The findings reveal a strong correlation between channel evolution,flood events,and climate change.Numerous flood events that occurred from the Late Qing Dynasty to the World War II caused a high rate of channel evolution,demonstrating the combined effects of climate change and human activities.These findings will help adopt robust and resilient hydrological management methods in the future of a changing climate.
文摘Objective： To evaluate the efficacy and safety of Qing Dai （indigo naturalis）, a traditional Chinese medicine, in the treatment for chronic hemorrhagic radiation proctitis. Methods： Ten patients with chronic hemorrhagic radiation proctitis between January 2005 to January 2008 were treated with Qing Dai. Qing Dai was administered orally at a dose of 1.5 g, bid for 5 consecutive days, every 2 weeks for two courses. Patients were followed up every 3 months. The clinical response and side-effects were evaluated. Results： Six patients showed improvement of rectal bleeding to grade 0-1 after 1 course of Qing Dai therapy. Four patients had reduced rectal bleeding to grade 0-1 after 2 courses of the therapy. The median follow-up time was 10 months （range： 6-24）. During the follow-up period, 1 patient experienced recurrent rectal bleeding and was managed with topical formalin dabbing, which controlled the symptom. No treatment toxicity was observed. Conclusion： Qing Dai may be a safe and effective treatment for chronic hemorrhagic radiation proctitis.
