ABSTRACT
Radiation-induced brain injury (RBI) is the most serious complication of head and neck tumor after radiotherapy. The pathogenesis of RBI is complicated, and the clinical course is irreversible, while no effective treatment available. The activation of glial cells is one of the main theories of RBI, and the prevention and treatment of RBI by targeting glial cells is the focus of current research. As a post-transcriptional regulatory factor, microRNA (miRNA) has been confirmed to be involved in regulatingglial cell radiosensitivity, inflammation type transformation, autophagy, exosomatic, long non-coding RNA (lncRNA), circular RNA (circRNA) and other related pathways, thereby mediating the occurrence and development of cascade reaction of inflammatory injury and neurological function repair of central nervous system (CNS) disease. Therefore, the establishment of miRNA - glial regulatory network may provide a new strategy for the prevention and treatment of RBI.
ABSTRACT
[Objective] To explore the effects of the traditional Chinese drugs Chaiyuwendantang(CYWDT) and its component on the plasm levels of ACTH,COR and cAMP in hippocampus of depressed mode.[Methods] Eighty——four male rats were divided into seven groups: control group,depressed model group,group of CYWDT,group of HuaTan,group of TiaoQiXue,group of YangXinPi,group of maprotiline equally and made up models in chronic unpredictable mild stress(CUMS).The plasm levels of ACTH,COR and the level of cAMP in hippocampus were detected by radioimmunoassay.[Results] We found that the plasm levels of ACTH,COR were significantly increase and cAMP in hippocampus was significantly decreasd in depression model of rat.CYWDT and TiaoQiXue could significantly decreased the level of ACTH(P
ABSTRACT
Objective:To study the effects of effective herbs in Yinchenhao Decoction(YD)on fatty deposition and TNF-?secretion of hepatic lipo-toxicity model in vitro.Methods:TG and TNF-?as the inspection target,apply the steatosis with TNF-?secretion lipo-toxicity model in vitro of HepG2 induced by long-chain FFA and uniform design U7(76)form for YD,which had 3 herbs,to compound 6 kinds of different prescriptions,in order to look for the effective herbs or optimized group in YD.Results:The Chinese medicine Yinchen and its optimized group-Yinchen and Zhizi combination can remarkably reduce the TG and TNF-?content.Conclusion:The Chinese medicine Yinchen and its optimized group-Yinchen and Zhizi combination were effective herbs in YD for inhibiting fatty deposition and TNF-?secretion of hepatic lipo-toxicity model in vitro.
ABSTRACT
Objective:To study the anti-depression mechanism of Chaiyuwendan Decoction(CYWDD).Methods:Rat models were established by separation and chronic unpredictable mild stress(CUMS).Ethology of rats were detected by open-field test and sucrose consumption test,contents of monoamine neurotransmitters were detected by HPLC-ECD.Results:Compared with normal group,the weight,the frequency of crossing,rearing and the contents of consumption to sucrosum water in depressive disorder rats decreased significantly(P
ABSTRACT
Objective To explore effective ways for community health service institutions to change patients' health service seeking patterns. Methods Yuetan Community Health Service Center of Fuxing Hospital affiliated to Capital Medical University and 9 community health service stations under its subordination in the 1996～2002 period were selected as a representative of the community health service institutions to be studied and intervened while the headquarters of Fuxing Hospital in the same period was selected as a representative of the third-tier hospitals to be studied. A comparison was made between the two in outpatient volume change. Questionnaires were distributed randomly to residents of the Yuetan area where Fuxing Hospital is located in order to study their health service seeking behaviors each year from 1996 to 2002. Results As a result of hard work in the 6 years, Yuetan Community Health Service Center saw a steady increase in outpatient volume whereas the headquarters of Fuxing Hospital witnessed a steady decrease in outpatient volume. Survey via questionnaires sent randomly to permanent residents of the Yuetan area indicated a change in residents' health service seeking patterns. Conclusion It is effective and viable for community health service institutions to change patients' health service seeking patterns through providing social-psychological-biological community medical services, enhancing health education and setting up a two-way referral system with third-tier hospitals.
