Intrusive rocks were formed in the Neoproterozoic, whose Pb Pb ages range from (913±4) Ma to (1 011±4) Ma and U Pb concordia age is (703±15) Ma. The tectonic settings of the rocks are volcanic arc or syn collision. After the formation of the intrusive rocks, these rocks also experienced reconstruction of Caledonian metamorphism. Based on the Ar Ar dating of metamorphic mineral of muscovite, the metamorphic time is determined to range from (386.8±0.8) Ma to (389.44±3.70) Ma.展开更多

However, the flowering phase of common LJF varieties is so short, which seriously restricts the development of LJF industry. As a new cultivated kind of Lonicerae japonicae Flos, “Hua Jin 6” has characteristics in long flowering phase and conveniently picking, which makes it have a broad development prospect. The aim of this study is to provide scientific guidance for its suitable harvest period by measuring yield and quality of “Hua Jin 6” from different harvest time. Studies show that flower size had a slowly rising trend from the first day to the seventh day, and then slowly declined or kept stable. There were no significant differences of total phenolic acid contents in different samples from different days, but contents of total flavonoids were on the rise and up to maximum in the ninth day. The contents of total iridoids had an increasing tendency from the first day to the fifth day and then kept relatively stable in other days. We demonstrated that the quality of “Hua Jin 6” is relatively stable and suitable for harvesting in all flower buds white stage in term of HPLC fingerprints. Our findings can make it possible to select the suitable time for different harvest purpose.展开更多

文摘Objective:To investigate the characteristics of'Jin Shang',a specialized term in traditional Chinese medicine(TCM)theory,in young adults with chronic neck pain(CNP)and investigated the correlation of'Jin Shang'with pain intensity and living disabilities using cross-section study.Methods:The thickness of the bilateral splenius capitis and semispinalis capitis were measured by ultrasound imaging(USI)as the objective performance of'Jin Shang'.The visual analogue scale(VAS)and Northwick Park Questionnaire(NPQ)were used to assess pain intensity and living disability.The Student's t test was used to investigate the difference in neck extensor muscle(NEM)thickness between CNP patients and healthy controls.Pearson's correlation and multiple linear regression were applied to investigate the relationship between NEM thickness,pain intensity and disability.Results:Fifty-nine young adult CNP patients and 16 healthy controls were recruited in this study,in accordance with specific inclusion and exclusion criteria.The student's t test showed that in CNP patients,the thickness of the semispinalis capitis during isometric contraction was significantly thinner than that of healthy controls(P=.04).Pearson's correlation analysis also revealed significant relationships between NEM thickness,VAS,and NPQ,while multiple linear regression showed that the thickness of the NEM in CNP patients was a significant predictor of pain intensity and disability.Conclusion:There was a significant difference in the thickness of the NEM in young adults with CNP when compared to healthy controls.Alterations in the NEM thickness in both rest and contraction are moderately related to neck pain and living disabilities.Our results investigated the characteristics of'Jin Shang'using USI and revealed a correlation between'Jin Shang'and CNP symptoms,which demonstrates that NEM plays an important role in CNP.

文摘Objective Ultraviolet B(UVB)mainly acts on the skin epidermis,causing oxidative damage and apoptosis of keratinocytes.Jin Bai Mei Yan Prescription(JBMYP)comprises a variety of antioxidant traditional Chinese medicines(TCM).In this study,we aimed to evaluate the effects of JBMYP on the oxidative damage induced by UVB in human immortalized epidermal keratinocytes(HaCaT)cells.Methods HaCaT cells were divided into six groups:control group,model(UVB)group,positive(UVB+vitamin E)group,UVB+JBMYP low dose group(160μg/mL),UVB+JBMYP moderate dose group(800μg/mL),and UVB+JBMYP high dose group(1600μg/mL).HaCaT cells were irradiated with UVB and treated with JBMYP for 24 h.Methyl thiazolyl tetrazolium(MTT)assay and real-time unlabeled cell function analyzer were used to assess the cell survival and proliferation rates,respectively.At the same time,the levels of intracellular reactive oxygen species(ROS),lipid peroxide malondialdehyde(MDA),glutathione(GSH),and hydroxyproline(HYP),as well as the activities of antioxidant enzyme superoxide dismutase(SOD)and catalase(CAT)were evaluated using enzyme linked immunosorbent assay(ELISA).Results Compared with the model group,the survival rate of HaCaT cells in each dosage group of JBMYP was significantly improved(P<0.05).Further,JBMYP could promote the proliferation of HaCaT cells,leading to a reduction in the contents of MDA and ROS,and increase in the contents of SOD,CAT,GSH and HYP in HaCaT cells.Conclusions JBMYP has enhanced protective effect on oxidative damage induced by UVB in HaCaT cells.

文摘A rapid method based on rapid resolution liquid chromatography(RRLC) coupled with a diode array detector(DAD) was developed for the simultaneous determination of six major constituents(magnoflorine,jatrorrhizine,coptisine,palmatine,berberine and evodiamine) in traditional Chinese medicine(TCM) Zuo Jin Pill(ZJP).The satisfactory chromatographic separation was carried on an Eclipse Plus C18 column(1.8 μm i.d.,150 mm×4.6 mm) by linear gradient elution with a mobile phase of acetonitrile-acetate buffer.All the calibration curves show good linearity(r2 0.9998).The detection limits and quantification limits ranged in 1.4―12 ng and 4.8―30 ng,respectively.The intra-and inter-day precisions were less than 0.63% with accuracies 98.60%―100.78%,and the recoveries were from 99.45% to 100.46%.Furthermore,hierarchical cluster analysis(HCA) was used to evaluate the variation of the herbal prescription.The results demonstrate that this analytical method is simple,sensitive and reliable for rapidly analyzing six major bioactive compounds in ZJPs and is helpful to comprehensively evaluating the quality of this TCM.
文摘This paper introduced the origination of seclusion culture, analyzed historical background, causes, and aesthetic performances of hermit culture, took living style and life attitude of Tao Yuanming for example to summarize the location characteristics of villas under the impact of hermit culture in the Wei and Jin Dynasty. On this basis, site selection of Tianquan Julong International Eco-villa in Longquanyi District, Chengdu City was analyzed, and profound influence of hermit culture on the location aesthetics of modern villa explored.
