The Chinese classical novel Jin Ping Mei abounds with a large number of slangs,which correspondingly leads to the difficulty of the novel’s English translation and also gives rise to the emergence of diversified English versions.The two English translators,Clement Egerton and David Roy,adopted completely different translation strategies when dealing with Chinese slangs in the novel.Their different translation purposes account for the significant disparity concerning the slang translation.Clement Egerton pays more attention to the novel’s plot in his English version The Golden Lotus,rather than the unique expressions of the original language,so that in the concrete translation process,a domestication strategy is adopted for the sake of the target language readers’understanding,resulting in distortion and omission of the slang expressions in the translated text.By contrast,the translation purpose which guides David Roy’translation The Plum in the Golden Vase is to convey the complexity and literariness of the original Chinese text,and hence the foreignization strategy is employed concerning slang translation,which aims to accurately reproduce the unique expressions of slangs in the original text.Comparatively speaking,David Roy’s translation succeeds in preserving the Chinese slangs to the greatest extent both in form and meaning,and can shed light for the slang translation in other Chinese literary works. 展开更多

Heidan disease(black jaundice)is a kind of jaundice,which is caused by lingering and chronic jaundice,often with blood stasis and damp-heat,etc.The clinical symptoms of Heidan disease(black jaundice)are similar to those of cirrhosis caused by multiple chronic liver diseases in Western medicine.Heidan disease(black jaundice)generally belongs to yin jaundice type,and the pathogenesis is mostly related to blood stasis and dampness stagnation,often with damp-heat residue.According to Zhongjing Zhang,the prescription Xiaoshi Fanshi powder for the treatment of Heidan disease(black jaundice)is based on the understanding that the nature of Heidan disease(black jaundice)is inseparable from the two key pathological factors of dampness and blood stasis.The treatment of jaundice should be based on removing blood stasis and dampness,supplemented by soothing the liver and promoting the transportation function of spleen,removing blood stasis and harmonizing the collaterals,and promoting diuresis and reducing jaundice.In the treatment of jaundice,removing blood stasis and purging turbidity should be stressed,and powerful tonification should be used with caution.Since blood stasis and turbidity are always intermingling and often complicated with damp heat,the method of warm drying should be used with caution.For promoting blood circulation,removing blood stasis,and dredging the liver-biliarycollaterals,drasticmedicine shouldbeused withcaution. 展开更多

From the isotopic dating study of gneissic granodiorite, the authors discovered magmatism of the Jinning cycle. 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

Objective To investigate the effectiveness of compound Chai Jin Jie Yu Tablets(CJJYT)in ameliorating cognitive impairment associated with depression and its potential mechanism of action.Methods In vitro experiments,the hippocampus was isolated from the whole brain of the fetal rat and cultured into hippocampal neuron cells.50μM corticosterone(CORT)was added to each group 18 h before the experiment for modeling depression,with the exception of the control group.After modeling,the blank serum group was added with 10%blank serum,the CJJYT group and the venlafaxine group were added with the corresponding 10%drug-containing serum,and the control group and the model group were added with equal volumes of culture medium.The intracellular Ca^2+mean fluorescence intensity,miniature excitatory postsynaptic current(mEPSC)current amplitude,and frequency of different hippocampal neurons were evaluated as indicators of synaptic function in the hippocampal neurons.In addition,the expression of synaptic plasticity related proteins,synaptophysin-α(SYN-α),N-methyl-D-aspartate receptor 2A(NR2A),N-methyl-Daspartate receptor 2B(NR2B),post synaptic density 95 protein(PSD-95),calcium/calmodulin dependent protein kinaseⅡ(CaMKⅡ)and synaptic associated protein(SynGAP)were detected in the hippocampal neurons by immunofluorescence staining and high content analysis(HCA)system.Then,reverse transcription-polymerase chain reaction(RT-PCR)was used to detect the mRNA expression levels of SYN-α,NR2A,NR2B,PSD-95,CaMKⅡand SynGAP.For in vivo experiments,except for those in the blank control group,all rats were treated within a single cage for chronic unpredictable stress-induced depression modeling and subjected to corresponding drug interventions.Behavioral tests were used to detect depressive behavior and determine learning,memory and other cognitive abilities,whereas enzyme-linked immunosorbent assay(ELISA)was used to detect the CORT levels.Golgi-Cox staining was used to observe changes in the synaptic morphology of parahippocampal gyrus CA1 area(CA1)and dentategyrus(DG).Results In vitro,CJJYT treatment reduced the intracellular Ca^2+mean flurorescence intensity in the hippocampal neurons(P<0.05),causing a reduction in the frequency and current amplitude of mEPSC(P<0.05),and thus inhibited the excessive activation of post-synaptic receptors.CJJYT treatment reduced the protein and mRNA expression of SYN-α,NR2A,NR2B and PSD-95 in the hippocampal neurons(P<0.05),increased the mRNA and protein expression of CaMKⅡand SynGAP(P<0.05),and thereby improved the synaptic plasticity of the hippocampal neurons.In vivo,CJJYT intervention improved sucrose preference,voluntary activity,learning and memory ability of Morris water maze test,and suppressed appetite(P<0.05),and increased the despair feeling of forced swimming test(P<0.05).The CORT level was reduced(P<0.05),leading to the repair of synaptic damage in the hippocampal neurons.Conclusions CJJYT can improve the synaptic function of hippocampal neurons and has obvious protective effects on neurons.It can repair the structural damage in the hippocampal neurons,improving the cognitive ability of the depressed model rats.The mechanism of CJJYT improving cognition in depressed rats may be related to the transmission and function of SYN-α/NR and its downstream neurotransmitters. 展开更多

Lonicerae japonicaeFlos (LJF) is widely used in traditional Chinese medicines for the treatment of various diseases, which is now in great demand every year and has a broad development prospect. 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

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. 展开更多
