Two lab-scale expanded granular sludge bed reactors were operated using granular sludge and river sediments as seed sludge respectively, through gradually lowering down the inner pH values, acid-tolerant methanogenic granular sludge with good methanogenic activity were acquired and formed. Two EGSB reactors could be operated steadily under the condition of pH 5.8~6.2, and their volumetric loading rates were about 5.5~7.5 kg COD/(m3/d), the COD removal efficiencies were about 90%. The granular sludges taken from two reactors could maintain relatively higher methanogenic activity under low pH, and the relative activities of the granular could be 51.78% and 55.6% of the value with the condition of pH 7.0 when pH was 5.5. Studies on the diameter distribution, settling velocities, concentrations of different metal elements and microbiological characteristics of these acid-tolerant granular sludges were also conducted.

OBJECTIVETo observe the clinical efficacy of comprehensive Western medical treatment plus Compound Yindan Decoction (CYD) in treatment of acute cholestatic hepatitis (ACH).
METHODSUsing randomized controlled study, 60 ACH patients in line with inclusive criteria were randomly assigned to the treatment group (treated by comprehensive Western medical treatment plus CYD) and the control group (treated by comprehensive Western medical treatment alone), 30 in each group. Scores for symptoms and levels of liver functions [total bilirubin (TBIL), direct bilirubin (DBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT), total biliary acid (TBA)] were observed before and after treatment.
RESULTSCompared with before treatment in the same group, total scores for symptoms decreased in the treatment group and the control group at the end of the 1st and the 4th week after treatment (all P < 0.05). Compared with the control group, total scores for symptoms decreased in the treatment group at the end of the 1st week (P < 0.05). Compared with before treatment, serum levels of TBIL, DBIL, ALP, GGT, and TBA all decreased in the two groups at the end of the 4th week after treat- ment (P < 0.01). Compared with the control group, serum levels of TBIL, DBIL, ALP, GGT, and TBA all decreased in the treatment group at the end of the 1st and the 2nd week after treatment (P < 0.05). Compared with the control group, the average time for TBIL and DBIL decreasing to the level less than five times the normal value was significantly shorter in the treatment group (P < 0.05).
CONCLUSIONCYD could significantly improve clinical symptoms of ACH patients, decrease serum levels of TBIL and DBIL, reduce serum levels of ALP, GGT, and TBA, obviously improve cholestasis, and promote the recovery.

Background The establishment of diabetic animal model is a crucial step for the study about diabetic eye diseases. At present,the main modeling method include the injection of streptozotocin and alloxan. But the shortcoming of the former is an expensive price, and that of the later is high death rate of animals. Objective This experiment was to discuss the way which decrease the death of alloxan-injected animal and explore the effects of high blood glucose on the posterior capsular opacification (PCO). Methods Forty clean healthy male New Zealand white rabbits were randomly divided into 2 groups. 90mg/kg of alloxan were injected via ear vein once in 20 rabbits to create the diabetic animal models,and the equivalent amount of normal saline solution was injected at the same way as normal blood glucose group. The successful models were selected in the animals with the blood glucose level over 12. 0 mmol/L two weeks later, and PCO of lens were graded based on the method of Odrieh under the slit lamp. Extracapsular lens extraction was then performed on the right eye of rabbits in both groups, and the posterior capsules were obtained from these eyes at the 6th, 10th and 14th days after operation. The expression of proliferating cell nuclear antigen ( PCNA ) in posterior capsular lens epithelial cell was detected by immunohistochemistry. Results The modeling successful rate was 70% after injection of alloxan. The body weight of rabbits in high blood glucose group was significantly lowed and the blood glucose was significantly elevated in comparison with normal blood glucose group ( all P<0. 05). Two weeks after surgery ,2 eyes occurred 2 grade of PCO and only one eye showed the 1 grade of PCO in the high blood glucose group. However, 1 grade of PCO was found in 3 eyes in the normal blood glucose group. Biopsy revealed that PCNA was positively expressed in the cell nuclei of LECs in high blood glucose group rather than the normal blood glucose group from the 10th day after surgery. The proliferation index of PCNA was 0. 86±0. 04 and 0. 25±0. 03 respectively in high blood glucose group and normal blood glucose group, showing a significant difference between them (t = -16. 171 ,P = 0. 000). Conclusion Stable diabetic models of rabbits can be created by intravenous injection of 90 mg/kg alloxan. High blood glucose level is one of the important factors for the development of PCO.

OBJECTIVETo observe effects of serum Bushen Huoxue prescription(Chinese characters) on classic Wnt/β-catenin signaling pathways of osteoblasts, and explore mechanism of Bushen Huoxue prescription (Chinese characters) for preventing osteoporosis.
METHODSTwenty health female rats were randomly divided into two groups, including Bushen Huoxue (Chinese characters) group and saline group,10 in each group. Bushen Huoxue (Chinese characters) group and Saline group were gavaged Bushen Huoxue and saline every day for 1 week. Bushenhuoxue containing serum and saline containing serum were got according to methods of serum preparation of drug-containing. The osteoblasts was cultured with neonatal rat skull according to Enzyme Consumer Law, and was identified by Wright-Giemsa staining (R-J) and alkaline phosphatase staining (ALP). The third generation of osteoblasts was divided into three groups, including saline group, normal group,Bushen Huoxue (Chinese characters) group. Each group were added to 15% appropriate medium. ALP activity of osteoblasts and osteoblasts proliferation rate were tested, mineralized nodules were observed, the expression of β-catenin, Runx2, Osx mRNA of osteoblasts were tested by RT-PCR.
RESULTSThere was blue granules in cytoplasm, cell nucleus was flint with 1 to 3 nucleoli showed by R-J staining, morphology of osteoblasts were cultured. ALP staining showed cytoplasm with purple granules, the results showed that the cultured cell was osteoblasts. The content of ALP in Bushen Huoxue (Chinese characters)group was (6.272±0.131) ,appreciation rate was (0.81? 0.172), and could significantly improve differentiation and proliferation activity of osteoblasts compared with Saline group (P< 0.01). There were four different size orange nodules, the Maximun nodule was 1.0 x 1.0 cm in Bushen Huoxue (Chinese characters) group after Alizarin red staining, the results showed Bushen Huoxue (Chinese characters)group could obviously improve mineralization of osteoblasts. The expression of mRNA of β-catenin, Runx2 and Osx in Bushen Huoxue (Chinese characters)group were (1.782±0.944), (1.935±0.994) and (1.610±0.811) by RT-PCR,it was significantly increased compared with saline group (P<0.01), but there was no difference between Bushen Huoxue (Chinese characters)group and normal group (P>0.05).
CONCLUSIONBushen Huoxue (Chinese characters)group could obviously promote differentiation, proliferation and mineralization of osteoblasts through activation of Wnt, β-catenin signaling pathway. It suggested that the mechanism of action of Bushen Huoxue (O'f f Il.t)particle clould prevent osteoporosis through the activation of Wnt, β-catenin signaling pathway.

OBJECTIVETo investigate the pathogenic infection and its drug resistance in expressed prostatic secretion (EPS) and its correlation with serum PSA, and provide some evidence for the systematic and normalized diagnosis and treatment of prostatitis.
METHODSThree EPS swabs were collected from each of the 320 prostatis patients following measurement of the serum PSA level, 1 for bacterial culture and identification, 1 for detection of Mycoplasma and drug sensitivity, and the other for examination of Chlamydia trachomatis antigen by colloidal gold immunoblot.
RESULTSTotally 244 strains were isolated from the 320 EPS samples, including 188 bacterial strains (dominated by Staphylococcus and sensitive to vancomycin or linezolid) and 44 Mycoplasma and Chlamydia strains (mainly Ureaplasma urealyticum and susceptible to josamycin or doxycycline). The serum PSA level was significantly higher in the pathogen-positive than in the pathogen-negative group ([6.98 +/- 0.56] microg/L vs [2.32 +/- 0.12] microg/L, P < 0.05).
CONCLUSIONProstatitis may lead to the elevation of the serum PSA level and the pathogens involved vary in their resistance to different antibacterial spectrums. Therefore, appropriate and individualized antibiotic therapy should be selected according to etiological diagnosis and the results of drug sensitivity test.
