| 1 | Temporal and spatial variations in hydrogeochemistry of cave percolation water and their implications for four caves in Guizhou, China显示文摘Soil water and cave drip water from four cave systems in Guizhou, Southwest China, were monitored and sampled monthly from April 2003 to May 2004 to understand spatio-temporal variations in hydro-geochemistry of cave percolation water. The results indicated that among the 5 drip water sites from the Liangfeng Cave (LFC), there were no significant differences among the hydro-geochemical parameters. In the Xiniu Cave (XNC), the drip rates were variable and responded quickly to precipitation events in the 3# (No. 3) drip site with variable water head; both bulk and variation in drip rates were smaller in the 2# with constant water head. However, in the Qixing Cave (QXC) and Jiangjun Cave (JJC), drip rates, concentrations of major ions and saturation index for calcite (SI C ) were smaller, and Mg/Ca ratios in Group I (1#, 2#, 6#, 7# and 8# in the QXC; 2# and 3# in the JJC) were larger than those in Group II (3#, 4#, 5# and 9# in the QXC; 1# and 4# in the JJC). These differences might be the result of different hydrogeological processes above the caves, which are divided into five categories based on hydro-geochemistry data. The formation of some proxies in speleothem, such as Mg/Ca, is likely to be affected by those processes. | LUO Weijun WANG Shijie XIE Xingneng ZHOU Yunchao LI Tingyu | 2013 | Chinese Journal Of Geochemistry2013，32，2： | 7 |
| 2 | Efficacy and safety of Yunxiangjing derived from Chinese herbal medicine administered as an enema in the management of acute radiation-induced proctitis in patients with pelvic malignancy显示文摘OBJECTIVE: To assess the efficacy and safety of Yunxiangjing(YXJ), derived from Chinese herbal medicine, in the management of acute radiation-induced proctitis(ARIP) in patients with pelvic malignancy.METHODS: Forty-eight patients with grade 2 ARIP were administered YXJ as an enema(1∶30 dilution)for 2 weeks and followed up for 2 years. All were assessed for response and ARIP grade. Quality of life(QOL) was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30.RESULTS: Of the 48 patients, six(12.5%) achieved complete remission of ARIP and 28(58.3%) showed a decrease from grade 2 to grade 1 ARIP. No patient experienced a grade ≥3 toxicity. At the end of radiotherapy, patients showed significant improvements in QOL(P < 0.05). Two years after treatment, 46 patients showed no late toxicity, with only two experiencing grade 1 late toxicity.CONCLUSION: YXJ can be used as an enema to manage acute radiation-induced proctitis in cancer patients undergoing radiotherapy. These findings suggest that YXJ enema may be an alternative treatment of ARIP. | Tang Huaying Huang Yinchun Mo Xingneng Yi Guisheng Wen Hui Guo Zhen Feng Kaihua Liu Yin Bu Qing Jiang Wei | 2016 | Journal of Traditional Chinese Medicine2016，36，1： | 7 |
| 3 | Three-dimensional fluorescence spectral characteristics of dissolved organic carbon in cave drip waters and their responses to environment changes: Four cave systems as an example in Guizhou Province, China显示文摘Understanding the responses of fluorescence spectral characteristics of cave drip waters to modern environment and climate changes is key to the reconstructions of environmental and climatic changes using fluorescence spectral characteristics of speleothems. The fluorescence spectral characteristics of dissolved organic carbon (DOC) in four active cave systems were analyzed with a three-dimensional (3D) fluorescence spectral analysis method. We found that the fluorescence types of DOC were mainly of fulvic-like and protein-like fluorescences, both in soil waters and cave drip waters. The intensity of fulvic-like fluorescence was positively correlated with the concentrations of DOC, suggesting that the DOC of cave drip waters was derived from the overlying soil layer of a cave system. Compared with the other cave systems, the variation range of the excitation and emission wavelengths for fulvic-like fluorescence of cave drip waters in Liangfeng cave system that had forest vegetation was smaller and the excitation wavelength was longer, while its fluorescence intensity varied significantly. By contrast, the excitation and emission wavelengths and fluorescence intensity for that in Jiangjun cave system that had a scrub and tussock vegetation showed the most significant variation, while its excitation wavelength was shorter. This implies that the variation of vegetation overlying a cave appears to be a factor affecting the fluorescence spectral characteristics of cave drip waters. | XIE XingNeng WANG ShiJie ZHOU YunChao LUO WeiJun | 2008 | Chinese Science Bulletin2008，53，6： | 5 |
| 4 | Stable Carbon Isotope Variations in Cave Percolation Waters and their Implications in Four Caves of Guizhou, China显示文摘Monitoring and sampling of main plants,soil CO2,soil water,bedrock,spring water,drip water and its corresponding speleothem were performed at four cave systems of Guizhou,Southwest China,from April 2003 to May 2004,in order to understand stable carbon isotope ratios variations of dissolved inorganic Carbon(DIC) in cave percolation waters(δ13CDIC) and their implications for paleoclimate.Stable carbon isotopic compositions and ions(Ca,Mg,Sr,SO4,Cl etc.) were measured for all samples.The results indicate that there are significant differences among the δ13CDIC values from inter-cave,even inter-drip of intra-cave in the four caves.The δ13CDIC values from the Liangfeng Cave(LFC) is lightest among the four caves,where vegetation type overlying the cave is primary forest dominated by tall trees with lighter average δ13C value(–29.9‰).And there are remarkable differences in δ13CDIC values of different drip waters in the Qixing Cave(QXC) and Jiangjun Cave(JJC),up to 6.9‰ and 7.8‰,respectively.Further analyses show that the δ13CDIC values in cave drip waters are not only controlled by vegetation biomass overlying the cave,but also hydro-geochemical processes.Therefore,accurate interpreting of δ13C recorded in speleothems cannot be guaranteed if these effects of the above mentioned factors are not taken into consideration. | LUO Weijun WANG Shijie XIE Xingneng ZHOU Yunchao LI Tingyu | 2013 | Acta Geologica Sinica(English Edition)2013，87，5： | 3 |
