The traditional Chinese medicine (TCM) literature database of jaundice is an important means of the realization of the standardization and digitalization of TCM liver disease syndrome differentiation and treatment.
This article analyzed the background of jaundice literature database and its establishment and significance . The building of TCM jaundice database was described in this paper from literature data source, TCM jaundice the-saurus, literature collection and analysis. A brief introduction was made on contents of the database and the function. Deficiencies of the literature database such as the standardization, quality, daily maintenance, talent and team training were also explained .

Retinitis pigmentosa (RP) is a hereditary disease characterized by the progressive loss of photoreceptor cells. Disease pathology primarily affects rod photoreceptor cells first but light-insensitive cone photoreceptor bodies can survivor longer. Delivered by adeno-associated viral vector or lentiviral vector, expression of microbial-type rhodopsin, channelrhodopsin-2 or archaebacterial halorhodopsin in the survived retinal cells can substitute for the native phototransduction cascade in mouse models of retinitis pigmentosa. It can also restore light sensitivity and activate all retinal cone pathways and drive sophisticated retinal circuit functions. Thus, expression of channelrhodopsins or halorhodopsin might be a potential strategy for the restoration vision of patients with RP.

Objective To investigate the changes of expression of quinone oxidoreductase-1 (NQO1) and heme oxygenase-1 (HO1) at protein and mRNA levels in the brains of rats with chronic fluorosis,effect on NF-E2-related factor 2/antioxidant response element (Nrf2/ARE) signal pathway,and reveal the mechanism of brain damage induced by the disease.Methods SD rats were randomly divided to two groups of 30 each (half females and half males),e.g.the normal control group (drinking water containing less than 0.5 mg/L of fluorine) and fluoride exposed group (drinking water containing 50.0 mg/L sodium fluoride,NaF).All rats were examined at the 10 months after feeding NaF.Dental fluorosis of rats was observed; the fluoride contents in urine and bone were detected by fluoride-ion selective electrode; protein and mRNA levels of NQO1 and HO1 in brains were detected by Western blotting and quantitative real timePCR,respectively.Results The dental fluorosis was observed,and contents of fluoride in urine [(2.16 ± 0.39)mg/L] and bone [(211.07 ± 40.52)mg/kg] determined in the rats of the fluoride group were higher than those of controls [(1.70 ± 0.24)mg/L,(34.67 ± 11.15)mg/kg,t =2.11,3.23,all P＜ 0.05].The protein expression levels of NQO1 and HO1 in the brains of rats with fluorosis [(255.2 ± 14.3) ％ and (187.2 ± 11.1)％] were also higher than those of controls [(100.0 ± 12.2)％,(100.0 t 8.9)％,t =2.14,2.05,all P ＜ 0.05]; the mRNA levels of NQO1 and HO1 [(210.2 ± 9.8)％ and (154.5 ± 7.4) ％] in the rats of the fluoride group were increased as compared to those of controls [(100.0 ± 10.4)％,(100.0 ± 9.7)％,t =2.33,2.75,all P ＜ 0.05].Conclusion The expression of NQO1 and HO1 in brain of rats with fluorosis are significantly increased,which may be due to the activation of Nrf2/ARE signal pathway and may play a compensative role in enhancing antioxidant ability.

Objective To detect the expression of muscarinic acetylcholine receptors (mAChRs) at mRNA and protein levels in the brain of rats with chronic fluorosis and to reveal the role of the receptors in brain injury and learning and memory deficits.Methods Sixty healthy SD rats were divided into two groups (30 rats in each group,half males and half females) by random number table method according to body weight.In the control group,the rats were fed with drinking water containing no more than 0.5 mg/L fluoride; in the fluoride group,the rats were fed with high doses of sodium fluoride in drinking water (50.0 mg/L).Each group was fed with normal diet (6.2 mg/kg).After being exposed to fluoride for 10 months,behavioral performance was measured with Morris water maze,including the escape latency time and the numbers of crossing platforms.After being sacrificed,rat brains were taken and weighted.M1 and M3 subunits at mRNA and protein levels were detected by real-time PCR and Western blotting,respectively; the correlation between protein levels of the receptor subunits and the ability of learning and memory was analyzed.Results In fluoride group,the escape latency time [(21.68 ± 2.90)s] was significantly longer than that of control group [(6.14 ± 1.71)s,t =0.289,P ＜ 0.05]; and the number of crossing platforms [(11.62 ± 2.26)times] was significantly decreased as compared to that of control group [(19.00 ± 3.69)times,t =0.352,P ＜ 0.05].Furthermore,the mRNA expression [(17.07 ± 6.89)％,(12.25 ± 5.03)％] and the protein levels [(71.07 ± 6.89)％,(32.25 ± 4.66)％] of M1 and M3 receptors in rat brains were significantly lower as compared to those of controls [(100.00 ± 3.00)％,(100.00 ± 2.15)％ and (100.00 ± 9.01)％,(100.00 ± 10.33)％,t =0.210,0.157,0.095,0.296,all P ＜ 0.05].The escape latency and M1,M3 protein levels were negatively correlated (r =-0.683,-0.700,all P ＜0.05),and the number of space exploration and M1,M3 protein levels were positively correlated (r =0.867,0.837,all P ＜ 0.05).Conclusion Declined expression of mAChRs at mRNA and protein levels have been detected in the brain of rats with chronic fluorosis,which may be one of the main mechanism concerning the learning and memory deficits.
