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 detect the levels of oxidative stress in brain and serum of rats with chronic fluorosis and the antagonistic effects of vitamin E (VitE),and to reveal the role of oxidative stress in brain injury.Methods Thirty healthy SD rats were divided into three groups based on body weight by means of a random number table (10 rats in each group,half male and half female).In the control group,the rats were fed with drinking water containing less 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) and the VitE antagonistic group were fed with the same content of fluoride in drinking water as the fluoride group,but adding VitE (50.0 mg/kg) by intragastric administration once a day.All rats were fed with normal diet (6.2 mg/kg).After exposure to fluoride for 10 months,all rats were put to death,dental fluorosis of the rats was examined and the fluoride content in bone was determined by fluoride-ion selective electrode;the activity of superoxide dismutase (SOD) was determined by the xanthine oxidase method and glutathione peroxidase (GSH-Px) by the colorimetric method,the level of malonaldehyde (MDA) by the glucosinolates barbituric acid fluorescence method and the levels of OH-,H2O2 and O-·2 in rat serum and/or brain were detected by the colorimetric method.Results In the rats of the fluoride group,fluoride content in bone was higher as compared to control [bone fluoride:(211.07 ± 48.52) vs.(33.40 ± 9.26) mg/kg,P ＜ 0.01].The activities of SOD and GSH-Px in rat brains of the fluoride group [(20.10 ± 1.98) kU/g,(28.70 ± 19.35) kU/L] were significantly lower than those of controls [(37.05 ± 3.13) kU/g,(59.63 ± 12.83) kU/L,all P ＜ 0.01],the activity of SOD in VitE antagonistic group [(26.27 ± 1.74) kU/g] was higher than the fluoride group (P ＜ 0.01);the activities of SOD and GSH-Px in rat serum of the fluoride group were significantly decreased [(11.55 ± 1.75) kU/L,(79.50 ± 19.18) U/L] than those of controls [(20.79 ± 2.43) kU/L,(170.00 ± 14.68) U/L,all P ＜ 0.01],the activity of SOD in VitE antagonistic group [(17.23 ± 0.68) kU/L] was higher than the fluoride group (P ＜ 0.01).The levels of MDA in rat brain and serum of the fluoride group [(8.84 ± 0.69) μmol/L,(1.46 ± 0.11) nmol/L] were significantly higher than those of controls [(1.27 ± 0.74) μmol/L,(0.83 ± 0.10) nmol/L,all P＜ 0.01],VitE antagonistic groups [(4.51 ± 1.13) μmol/L,(1.29 ± 0.02) nmol/L] were lower than the fluoride groups (all P ＜ 0.01).The levels of OH-,H2O2 and O-·2 in rat brains of the fluoride group [(24.24 ± 1.80) kU/g,(15.28 ± 2.97) mmol/L,(6.53 ± 0.96) U/g] were significantly higher than those of controls [(11.44 ± 1.63) kU/g,(5.28 ± 1.20) mmol/L、,(2.93 ± 0.42) U/g,all P ＜ 0.01],VitE antagonistic groups [(14.43 ± 0.76) kU/g,(8.09 ± 0.55) mmol/L,(4.41 ± 0.49) U/g] were lower than the fluoride groups (all P ＜ 0.01).Conclusions Elevated levels of oxidative stress are found in brain and serum of the rats with chronic fluorosis,which may be a main mechanism of brain injury.VitE may play an important antagonistic role in oxidative damage induced by fluoride toxicity.

Objective To observe the expression of NF-E2-related factor 2 (Nrf2) and Kelch-like ECH-associated protein-1 (Keap1) at mRNA and protein levels in the brain of rats with chronic fluorosis and to reveal the mechanism of brain damage induced by the factors.Methods Ninety SD rats were divided into three groups (30 rats in each group,half male half female) by the random number table method according to body weight.The control group was fed with normal tap-water,high-fluoride group with 50 mg/L fluoride (NaF) added in drinking water;and the high-fluoride plus vitamin E (Vit E) group with the same dose of NaF as the high-fluoride group,but giving 5 mg/kg Vit E by intragastric administration.The experiment period was 10 months.The fluoride contents in urine and bone were detected by fluoride-ion selective electrode.The protein and mRNA levels of Nrf2 and Keap1 in brain of rats were detected by Western blotting and quantitative real time PCR,respectively.The activity of superoxid dismutas (SOD) and the content of lipid peroxidation (MDA) were measured by biochemistry methods.Results Dental fluorosis was detected in high-fluoride group.The differences of fluoride contents in urine and bone were statistically significant between groups (F =6.87,182.87,all P ＜ 0.05).The urine fluoride [(2.16 ± 0.39),(2.07 ± 0.15)mg/L] and bone fluoride [(211.07 ± 40.52),(82.09 ± 28.60)mg/kg] in the high-fluoride and high-fluoride plus Vit E groups were higher than those of the control group [(1.70 ± 0.24)mg/L,(34.67 ± 11.15)mg/kg,all P ＜ 0.05].The differences of mRNA and protein levels of Nrf2 and Keap1 in brains of rats,SOD activity,MDA content were statistically significant between groups (F =654.33,432.87,447.45,398.88,68.34,68.34,all P ＜ 0.05).The mRNA levels of Nrf2 and Keap1 [(320.18 ± 6.83)％,(267.37 t 7.22)％] were increased compared to those of control group [(100.00 ±3.00)％,(100.00 ± 2.75)％,all P ＜ 0.05];the protein levels of Nrf2 and Keap1 [(283.28 ± 6.89)％,(196.32 ± 5.57)％]were also raised compared with those of control group [(100.00 ± 8.71)％,(100.00 ± 9.23)％,all P ＜ 0.05];the activity of SOD [(22.10 ± 2.10)μ,mol/kg] in brain of rats in fluoride group was significantly lower and the content of MDA [(8.63 ± 0.77) μmol/kg] was higher than those of control group [(35.05 ± 2.98),(1.25 ± 0.64) μmol/kg,all P ＜ 0.05].In high-fluoride plus Vit E group,the mRNA levels of Nrf2 and Keap1 [(243.23 ± 5.34)％,(180.54 ± 4.48)％] and the protein levels of Nrf2 and Keap1 [(210.88 ± 4.79)％,(150.68 ± 6.49)％] were lower than those of high-fluoride group (all P ＜ 0.05);the activity of SOD [(26.33 ± 1.84)μmol/kg] was significantly higher and the content of MDA [(4.88 ± 0.84)μmol/kg] was lower than that of high-fluoride group (all P ＜ 0.05).Correlation analysis showed that increased levels of Nrf2 and Keap1 were positively correlated with the level of MDA in rat brain (r =0.69,0.33,all P ＜ 0.05),but negatively correlated with the activity of SOD (r =-0.78,-0.80,all P ＜0.05).Conclusion The expression of Nrf2 and Keap1 in brain of rats with fluorosis is significantly increased and positively correlated with the content of fluoride in bone and the level of oxidative stress,whereas vit E can attenuate these abnormal changes induced by fluoride,which might be one of the mechanisms of brain damage of the disease.
