Botanical drugs for bruises used in the Xiangxi region of China, a place rich in martial culture

Background:Xiangxi Tujia and Miao Autonomous Prefecture,located in Hunan Province,China,is a culturally rich region with a diverse population.The locals have a deep martial arts history and possess a wealth of traditional knowledge for treating bruises.Methods:In order to investigate this topic,we conducted ethnobotanical studies by visiting local medicinal markets and conducting interviews.Results:We identified 43 botanical drugs used for treating bruises,categorized into four types:sprains,contusions,strains,and bone injuries.The local people typically prefer to mash these botanical drugs freshly or make medicinal wine for external use.Treatment often involves a combination of drugs to promote blood circulation and remove blood stasis,with medications to dispel rheumatism,clear heat,and detoxify,tailored to the humid climate and high precipitation in mountainous areas.Based on the fidelity level values,the local plant resources with high acceptance,utilization,or potential value in the treatment of bruises included Sargentodoxa cuneata,Lycopodium japonicum,Dioscorea cirrhosa,Panax japonicus,Achyranthes bidentata,Lysimachia heterogenea and so on.Conclusion:Herbal medicine and related knowledge for treating bruises are diverse and rich in the Xiangxi region.However,the local traditional medicinal knowledge faces challenges regarding inheritance due to regional modernization.Therefore,it is crucial to protect and further study this knowledge in the future.

Spatial Distribution of Carbon and Nitrogen in Sediments of Xiangxi River

[Objective] This study was conducted to explore the spatial distribution of carbon and nitrogen in the sediments of Xiangxi River, which was the biggest tribu- tary near the Three Gorges Dam. [Method] Sediment samples were collected using customized cylindrical samplers at three sites along Xiangxi River estuary in May, 2015 to measure the contents of total carbon, total nitrogen and an isotope of car- bon δ^13C. [Result] The total carbon content in the sediments varied from 1.74% to 3.52%, and the total nitrogen content varied from 0.1% to 0.3%. The average total carbon content in the sediments near the estuary was lower than in the upstream. The total carbon content in the sediments near the estuary gradually decreased with depth increasing. However, the variations in total nitrogen content in both horizontal direction （along the river from the estuary to the upstream） and vertical direction were not so obvious as in total carbon content. The isotopic analysis showed the δ^13C value increased with depth increasing. The overall δ^13C near the estuary was lower than that in the upstream. [Conclusioal The results will provide scientific refer- ences for the distribution of biogenic elements in sediments of Xiangxi River and the evolution process of aquatic ecosystem.

Prediction of chlorophyll a concentration using HJ-1 satellite imagery for Xiangxi Bay in Three Gorges Reservoir

Since the impoundment of the Three Gorges Reservoir in 2003, algal blooms have frequently been observed in it. The chlorophyll a concentration is an important parameter for evaluating algal blooms. In this study, the chlorophyll a concentration in Xiangxi Bay, in the Three Gorges Reservoir, was predicted using HJ-1 satellite imagery. Several models were established based on a correlation analysis between in situ measurements of the chlorophyll a concentration and the values obtained from satellite images of the study area from January 2010 to December 2011. Chlorophyll a concentrations in Xiangxi Bay were predicted based on the established models. The results show that the maximum correlation is between the reflectance of the band combination of B4/（B2＋B3） and in situ measurements of chlorophyll a concentration. The root mean square errors of the predicted values using the linear and quadratic models are 18.49 mg/m3 and 18.52 mg/m3, respectively, and the average relative errors are 37.79% and 36.79%, respectively. The results provide a reference for water bloom prediction in typical tributaries of the Three Gorges Reservoir and contribute to large-scale remote sensing monitoring and water quality management.

Effects of different dietary energy and protein levels and sex on growth performance,carcass characteristics and meat quality of F1 Angus x Chinese Xiangxi yellow cattle

Background：The experiment evaluated the effect of nutrition levels and sex on the growth performance,carcass characteristics and meat quality of F1 Angus × Chinese Xiangxi yellow cattle.Methods：During the background period of 184 d,23 steers and 24 heifers were fed the same ration,then put into a2×2×2 factorial arrangement under two levels of- dietary energy（TON：70/80%DM）,protein（CP：11.9/14.3%DM）and sex（S：male/female） during the finishing phase of 146 d.The treatments were-（1） high energy/low protein（HELP）,（2） high energy/high protein（HEHP）,（3） low energy/low protein（LELP） and（4） low energy/high protein（LEHP）.Each treatment used 6 steers and 6 heifers,except for HELP- 5 steers and 6 heifers.Results：Growth rate and final carcass weight were unaffected by dietary energy and protein levels or by sex.Compared with the LE diet group,the HE group had significantly lower dry matter intake（DMI,6.76 vs.7.48 kg DM/d）,greater chest girth increments（46.1 vs.36.8 cm）,higher carcass fat（19.9 vs.16.3%） and intramuscular fat content（29.9 vs.22.8%DM）.The HE group also had improved yields of top and medium top grade commercial meat cuts（39.9 vs.36.5%）.The dressing percentage was higher for the HP group than the LP group（53.4 vs.54.9%）.Steers had a greater length increment（9.0 vs.8.3 cm）,but lower carcass fat content（16.8 vs.19.4%） than heifers.The meat quality traits（shear force value,drip loss,cooking loss and water holding capacity） were not affected by treatments or sex,averaging 3.14 kg,2.5,31.5 and 52.9%,respectively.The nutritive profiles（both fatty and amino acid composition） were not influenced by the energy or protein levels or by sex.Conclusions：The dietary energy and protein levels and sex significantly influenced the carcass characteristics and chemical composition of meat but not thegrowth performance,meat quality traits and nutritive profiles.

Study on Phosphorus Characteristics in Sediments of Xiangxi Bay, China Three-Gorge Reservoir

To explore the environment influence of the sediments in Xiangxi Bay (China Three-Gorge Reservoir), spatial and temporal distribution characteristics of total phosphorus (TP), phosphorus fractions, dissolved total phosphorus (DTP) of pore water and overlying water in the sediments were investigated. In surveys, the sampling was undertaken from six sites of Xiangxi Bay on 29 March 2009 and 28 March 2010. TP contents ranged from 1111.29 mg/kg to 1941.29 mg/kg with the mean value of 1533.09 mg/kg in 2009 spring and 1600.48 mg/kg in 2010 spring. Five fractions of sedimentary phosphorus, including loosely sorbed phosphorus (NH4Cl-P), redox-sensitive phosphorus (BD-P), metal oxide bound phosphorus (NaOH-P), calcium bound phosphorus (HCl-P), and residual phosphorus (Res-P), were separately quantified. DTP of pore water and overlying water all have positive correlations with NH4Cl-P and BD-P, which indicated that NH4Cl-P and BD-P were the main fractions that can easily release phosphorus in the sediments of Xiangxi Bay.

TEMPORAL AND SPATIAL DISTRIBUTION OF PHOSPHORUS IN THE XIANGXI RIVER

The phosphorus in water and sediment collected at different time from the Xiangxi River were analyzed. The results indicated that the phosphorus pollution have significant relations to human activities (especially the phosphorus industry). The concentrations of total-phosphorus (TP), total dissolved phosphorus (TDP) and dissolved phosphorus (DP) in Dec.2004 were higher than those in Jul. 2005; the TP contents of sites 15 and 16 were much higher than others’, the TP content of the largest site 16 was 1946.29mg/kg in Dec. 2004 and 1756.11mg/kg in Jul. 2005, respectively, which was much higher than the average (1497.51mg/kg and 1369.38mg/kg, respectively). The TP content in the sediment of the Xiangxi River was from 1179.53mg/kg to 1851.20mg/kg. The TP contents of most sites except site 18, 19 and 20 were higher in Dec. 2004 than those in Jul. 2005. The aluminium-phosphorus (Al-P) content in the sediment was obviously higher in Jul. 2005 than that in Dec.2004, which indicated that the stability of Al-P has a significant relation to the change of season.

Influence Factors Analysis to Chlorophyll a of Spring Algal Bloom in Xiangxi Bay of Three Gorges Reservoir

To study the relationship between environmental variables and chlorophyll a of spring algal bloom in Xiangxi Bay of Three Gorges Reservoir, stepwise multiple binomial regression and grey relative analysis methods were adopted. In surveys, 13 stations have been investigated and 143 samples were collected weekly from March 4 to May 13 in 2007. The study shows environmental variables (turbidity, total nitrogen, dissolved oxygen, total phosphates and silicate) are key factors during algal bloom. The grey relative values and their permutation indicated that turbidity was the most important factor and had comprehensive effect on chlorophyll a. The more number of interactive variables is found to be an indication of biochemical activity during spring algal bloom in Xiangxi Bay such as DO×TN, Turb×TP and so on. There was good linear relationship between chlorophyll a and the interaction of DO with TN ( , ).The interac-tion of nutrients (TP×TN, TP×SiO4, TN×SiO4) had significant influence to chlorophyll a and probably determined the inter-specific competition at different nutrient concentrations.
