ABSTRACT
Liver is no longer the only organ in the concept of anatomy,but it is a concept that has some specific functions in the visceral manifestations of liver.Liver is wood in the five element theory.It is yang of yin.Liver qi connects to the spring qi.Therefore,the liver function is to dredge and smooth qi of the whole body,which influences the blood and body fluid operation,the operation of the spleen and stomach,emotional changes and reproductive function and many other aspects.Suwen said "liver stores blood",which means that liver has the function of storing,regulating and controlling blood."Liver corresponds to the spring",which means changes in four seasons can affect the function of organs,but also contain the disease occurrence with a seasonal concept,which is an important part of visceral manifestation of liver.Modern medical research achieved some results from the nerve-endocrine-immune network,traditional four-axis,liver-blood vessels as the starting point for the liver as the theoretical mechanism of in-depth study.It was found that depression due to liver failed in soothing was related to the central cortex,the marginal system and the hypothalamicpituitary-adrenal (HPA) axis.The study covered neuropeptide and neurotrophic factor,monoamine neurotransmitter,central amino acid level,and etc.Liver stores blood,which is related to human coagulation system,EPO pathway and hemorheology.Liver corresponds to the spring,which is related to the neuroendocrine-immune network.And the pineal gland may be the highest regulatory site.At present stage,the study was conducted on the microcosmic mechanism of liver visceral manifestations from the gene and protein level.It was used to verify the regulation of liver function abnormality caused by the regulation of liver function in order to greatly explore the biological basis of traditional Chinese medicine (TCM) theory.
ABSTRACT
Depression and anxiety is one of common mental illness that are being seriously harm to the physical and mental health of human being in recent years.Depression and anxiety are difficult to be well treated with a single and targeted drug,owing to its biological-psychological-social interaction pathogenic feature.Due to its own multicomponent characteristics,traditional Chinese medicine (TCM) compound Xiao-Yao (XY) powder can exert the antidepression and anxiety effects from multi-level,multi-link and multi-target.Based on previous studies on effect and mechanism of XY powder on anti-depression and anxiety of our group,we proposed that XY powder had two main characteristics when treating depression and anxiety,which were "two-way adjustment" and "multi-target,multisystem,multi-level".Additionally,to further clarify the pharmacodynamic material basis of XY powder,more importance is that we should depend on the variety of disciplinary research methods,focused on the TCM syndrome and the combination of disease and TCM syndrome,brought both disease evaluation and syndrome evaluation method,took the importance of gut-brain axis (GBA),and combined with the correlation between the formula and the syndrome.
ABSTRACT
OBJECTIVE:To investigate the medication safety status of Chinese patent medicines and related influence factors for residents in Guangdong province,and provide reference for better guarantee of medication safety for residents. METHODS:Questionnaires were randomly sent out among the residents in 3 cities of Guangdong province. The cognition,utilization habit and safety awareness,the ways to get the related information of Chinese patent medicines and purchase way were surveyed and ana-lyzed statistically. RESULTS:Totally 530 questionnaires were sent out and 514 valid questionnaires were collected with effective re-covery of 96.98%. There are 64.01% of respondents didn’t know the composition of Chinese patent medicines;50.39% didn’t know the contraindications of Chinese patent medicines;48.44% didn’t know the adverse drug reactions of Chinese patent medi-cines that they were using;23.47% had once broken the tablets when took them;65.18% didn’t know that the old people had less dosage than teenagers and 44.75% didn’t know that Chinese patent medicines couldn’t be taken with some western medicines. There were many ways to get the related information of Chinese patent medicines and purchase them,and the main sources were from doctors and pharmacists in drug stores;90.08% had purchased Chinese patent medicines in drug stores. CONCLUSIONS:During daily medication of Chinese patent medicines,the biggest problem for residents is that the weak awareness of medication safety,unreasonable medication behavior and habit caused by lack of related knowledge of medication safety,which may cause safety risks or happen medication safety problems. Therefore,the residents’education of self-medical knowledge should be intensi-fied,the management of prescription in drug stores should be enhanced,pharmaceutical service function of pharmacists should be played,supervision management of drug advertisement should be strengthened and the contents in drug instructions should be regu-lated.
ABSTRACT
Objective To investigate any correlation between diffusion tensor imaging (DTI) results and Montreal cognitive assessment (MoCA) scores after severe traumatic brain injury (TBI).Methods Eight male pa-tients with chronic severe TBI were given the MoCA (including memory,attention,speech and executive function).DTI was used to quantify the fractional anisotropy (FA) of white matter fiber tracts in the radial and longitudinal fasciculus,under longitudinal fasciculus,internal capsule,corpus callosum genu and body,and the cingulate cortex.Pearson correlation coefficients were calculated to quantify the correlation between the FA values and MoCA scores.Results There was a positive correlation between FA in the corpus callosum body,corpus callosum genu and the superior longitudinal fasciculus and MoCA total scores.Conclusion The MoCA scores of patients with chronic severe TBI are related to white matter damage in the corpus callosum body,corpus callosum genu and the superior longitudinal fasciculus.
ABSTRACT
Objective To observe the influence of Qizhi Yifei containing serum on the expression of MMP-9 and TIMP-1 mRNA in lung fibroblasts, and explore its mechanism. Methods Trypsin digestion method was used to extract fibroblasts from lung tissue in rats. All fibroblasts were cultured and trained to the fourth generation. Then they were randomly divided into control group, model group and drug serum group. The model group and drug serum group were firstly treated by DMEM with 0.002 5 μg/mL TGF-β1. The control group was treated by DMEM only. The control group and model group were then treated by DMEM with blank drug serum in concentration of 5%, and the drug serum group was treated by DEME with Qiahi Yifei containing serum in same concentration. After 48 and 72 hours, RT-PCR was performed to test the expression of MMP-9 mRNA and TIMP-1 mRNA of each group. Results After 48 hours, MMP-9 and TIMP-1 mRNA were significantly increased in model group and drug serum group compared with control group. There was no difference between model group and drug serum group. After 72 hours, MMP-9 mRNA was up-regulated in model group and was decreased in drug serum group compared with control group. There was no significant difference among the three groups on the expression of TIMP-1 mRNA. Conclusion Qizhi Yifei containing serum can decrease the up-regulated expression of MMP-9 mRNA in lung fibroblasts stimulated by TGF-β1.
