Objective To explore the clinical value of serological indicators in diagnosis of patients with different degree of liver cirrhosis.Methods 50 patients with liver cirrhosis and 50 patients with decompensate cirrhosis were selected.The control group had 50 patients.The serological indicators were statistically analyzed.Results TBIL and ALT in the decompensated liver cirrhosis group were (69.5 ± 7.0) μmol/L,(143.1 ± 14.2) U/L,which were higher than those of compensated liver cirrhosis group (44.6 ± 5.8) μmol/L,(77.4 ± 8.6) U/L (P ＜ 0.05),and those two groups were higher than the control group(P ＜ 0.05).Alb and ChE of decompensated liver cirrhosis group were (28.2 ± 3.7) g/L and (2024.39 ± 211.40) U/L,which were lower than those of the control group (36.1 ±3.7) g/L,(6169.36 ± 607.42) U/L and the compensated cirrhosis group [(34.7 ± 4.3) g/L,(3571.27 ± 310.01)U/L] (P ＜0.05).ChE of compensated cirrhosis group was lower than the control group (P ＜0.05).PA and ADA of decompensated and compensated liver cirrhosis group were (0.14 ±0.04)mg/L,(16.17 ± 1.94)U/L and (0.21 ±0.05) mg/L,(34.20 ± 3.29) U/L,the differences were statistically significant (P ＜ 0.05).A/G of decompensated and compensated liver cirrhosis group were (0.64 ± 0.29) and (1.06 ± 0.30),which were lower than the control group (1.51 ± 0.21) (P ＜ 0.05),and that of the decompensated cirrhosis group was lower than that of the compensated cirrhosis group(P ＜0.05).Ⅳ-C and LN of decompensated cirrhosis group were (97.4 ±9.8) μg/L and (205.7 ±20.1) μg/L,which were higher than those of compensated liver cirrhosis group (68.7 ± 7.5) μg/L and (124.1 ±11.8) μg/L and the control group(52.3 ±6.1) μg/L and (83.8 ±7.6) μg/L(P ＜0.05).And those of the compensated cirrhosis group were higher than the control group (P ＜ 0.05).HA and PC Ⅲ of decompensated cirrhosis group were (211.3 ± 16.4) μg/L and (168.1 ± 16.2) μg/L,which were higher than the control group (51.2 ±5.3) μg/Land (79.1 ± 8.0) μg/L (P ＜ 0.05).Conclusion The serological indicators had the important reference value for clinical diagnosis and prognosis of cirrhosis.

AIM:To develop a HPLC method for determining scutellarin and geniposide in Yinshanlian Granules(Herba Artemisiae scopariae,Herba Scutellariae barbatae, Fructus Gardemiae,etc). METHODS: The analysis was performed on Diamonsil C_(18)(200 mm?4.6 mm,5 ?m) with mixture of acetonitrile(A) and 0.1% phosphoric acid solution as mobile phase in gradient mode.The concentration of solvent A were 5%,33%,5% and 5% at 0,30,31 and 35 min,respectively.The detection wavelength was set at 240 nm and the column temperature was at 30 ℃.(RESULTS:)The linear calibration curves were obtained in the concentration range of 0.032-0.288 mg/mL for scutellarin and 0.009 6-0.086 4 mg/mL for geniposide.The average recoveries of scutellarin and geniposide were 100.6%(RSD=0.80%,n=9),102.6%(RSD=1.1%,n=9),respectively.CONCLUSION: The method is quick,simple,and reproducible,which can be used to control the quality of Yinshanlian Granules.

The massive water and steam are consumed in the production of cellulose ethanol, which correspondingly results in the significant increase of energy cost, waster water discharge and production cost as well. In this study, the process strategy under extremely low water usage and high solids loading of corn stover was investigated experimentally and computationally. The novel pretreatment technology with zero waste water discharge was developed; in which a unique biodetoxification method using a kerosene fungus strain Amorphotheca resinae ZN1 to degrade the lignocellulose derived inhibitors was applied. With high solids loading of pretreated corn stover, high ethanol titer was achieved in the simultaneous saccharification and fermentation process, and the scale-up principles were studied. Furthermore, the flowsheet simulation of the whole process was carried out with the Aspen plus based physical database, and the integrated process developed was tested in the biorefinery mini-plant. Finally, the core technologies were applied in the cellulose ethanol demonstration plant, which paved a way for the establishment of an energy saving and environment friendly technology of lignocellulose biotransformation with industry application potential.

Objective To study the influence of GM1 on hyperbilirubinemia-induced brain injury in neonatal rats and its possible mechanism.Method A total of 120 7-day-old Sprague-Dawley (SD) rats were randomly assigned into normal control group (n =40),hyperbilirubinemia group (n =40) and GM1 group (n =40).According to the different duration of hyperbilirubinemia,each group was further assigned into 5 subgroups,6 h,12 h,24 h,48 h and 72 h group (n =8).The model of neonatal rat with hyperbilirubinemia was established injecting bilirubin solution (100 μg/g) intraperitoneally.GM1 (10 mg/kg) was injected intraperitoneally immediately after the model was established in GM1 group.Immunohistochemical method was used to determine the expression of Bax in hippocampus.TUNEL method was used to measure the neural cell apoptosis index (AI) in the brain.Result Six hours after the hyperbilirubinemia model was set up,the expression of Bax and AI in hyperbilirubinemia group and GM1 group were examined.The median of AI were 33.5％ and 15.4％ respectively and the average grey value of Bax positive cells were 157.4 ± 2.8 and 162.9 ± 2.3.Both apoptosis cells and the expression of Bax were gradually increasing,and peaked at 72 h after the model was established.The median of AI were 55.5％ and 35.5％ respectively,and the average grey value of Bax positive cells were 127.8 ± 3.6 and 141.5 ±2.7 in hyperbilirubinemia group and GM1 group.And the expressions of Bax and AI in the control group were nearly undetectable.The expression of Bax and AI in GM1 group were lower than hyperbilirubinemia group,but higher than the control group,the differences were statistically significant (P ＜ 0.001).Conclusion Brain cells apoptosis is influenced by hyperbilirubinemia-induced brain injury and Bax may be involved in the process.GM1 may reduce the brain damage by inhibiting the expression of Bax to reduce the apoptosis of the brain cells.
