A strain of Cellulosimicrobium cellulans Ha8 was studied on its morphological, biological characteristics and its utilization of several kinds of benzoic compounds, the results showed this strain was Gram-positive, the long rod-shaped cells were changed into short rod-shape gradually. pH value from pH 6.0 to pH 9.0 and the temperature from 20 ℃ to 40 ℃ were good for its growth. It could not only hydrolyze protein and starch, use cellulose and pectin, decomposite chitin, liquify gelatin and fix nitrogen, but also use phenol, xylene, benzoic, cinnamic acids and diphenlamine as the sole carbon resource for its growth. It could tolerate 0 mmol/L~30 mmol/L, 0 mmol/L~8 mmol/L, 0 mmol/L~30 mmol/L, 0 mmol/L~15 mmol/L and 0 mmol/L ~ 40 mmol/L of benzoic acids, phenol, xylene, cinnamic acids and diphenlamine seperately, but could not use 2,4-dinitrophenol, o-Nitrophenol, 2-Methoxyphenol, aminobenzenesulfonic acid, catechol and o-Phenanthroline as its sole carbon resource.

AIM:To perform a new method for orbital implant and contracted socket through one time and its results. ·METHODS:Totally 114 patients 114 eyes, from January 2008 to June 2014, with contracted socket participated in this study. We incised the bulbar conjunctiva horizontally and excised scar tissue, then implanted the hydroxyapatite in the four extraocular muscles and tightly sutured the Tenon ' capsule. After that, we put the superior and inferior conjunctival petals backwards and sutured them to the Tenon ' s capsule. All the patients were divided into four groups according to the vertical diameter length of the conjunctival defect area:GroupⅠ:≤5mm; Group Ⅱ: 6-10mm; Group Ⅲ: 11-15mm; and Group Ⅳ: ≥16mm. These patients were followed up for 6mo to 3y to observe the conjunctival sac shaping and growth of conjunctiva. ·RESULTS:There were 64 cases in GroupⅠ, 31 cases in Group Ⅱ, 16 cases in Group Ⅲ and 3 cases in Group Ⅳ. All patients ' conjunctival defect was covered by new conjunctiva and scar tissue 4 to 6wk after surgeries. Ten cases had contracted socket; 2 cases had orbital implant exposure, requiring reoperation. Of the 114 cases, 8 had contracted socket and could use a smaller conformer, 106 could use a normal size conformer. ·CONCLUSION: When the conjunctival defect was ≤15mm, this new method can address the orbital implant and contracted socket at the same time. While it was ≥16mm, flap transplantation is necessary.

The market and literature were studied to understand the existing situation of Magnoliae Officinalis Cortex goods, and the collected samples were analyzed, combined with the actual production, a new standard of Magnoliae Officinalis Cortex commercial specification and grade was drafted. Magnoliae Officinalis Cortex goods was divided into two categories according to the source in the old standard. Then each category was divided into four kinds of specifications according to the site. Each kind of specification was divided into several grades according to the length and weight. To judge the quality of Magnoliae Officinalis Cortex goods was mainly based on the appearance quality. In the new standard, the classification of commercial specification and grade is based on the thickness, magnolol and honokiol content. The goods of Magnoliae Officinalis Cortex can be divided into three specifications: Tongpu, Genpu and Doupu. Tongpu is divided into three grades, the remaining two are not graded.

In order to construct a eukaryotic co-expression plasmid containing membrane-anchored Sjcl4FABP and Sjc26GST genes and identify their expression in vitro, Sj14 and Sj26 genes were obtained by RT-PCR with total RNA of Schistosoma japonicum adult worms as the template and cloned into eukaryotic expression plasmid pVAC to construct recombinant plasmids pVAC-Sj14 and pVAC-Sj26. Then a 23 amino-acid signal peptide of human interleukin-2 (IL-2) upstream Sj14 or Sj26 gene and a membrane-anchored sequence containing 32 amino-acids of carboxyl-terminal of human placental alkaline phosphatase (PLAP) downstream were amplified by PCR as the template of plasmid pVAC-Sj14 or pVAC-Sj26 only to get two gene fragments including Sj14 gene and Sj26 gene. The two modified genes were altogether cloned into a eukaryotic co-expression plasmid pIRES, resulting in another new recombinant plasmid pIRES-Sj26-Sj14. The expression of Sj14 and Sj26 genes was detected by RT-PCR and indirect immunofluorescent assays (IFA) when the plasmid pIRES-Sj26-Sj14 was transfected into eukaryotic Hela cells. Restriction enzyme analysis, PCR and sequencing results revealed that the recombinant plasmids pVAC-Sj14, pVAC-Sj26 and plRES-Sj26-Sj14 were successfully constructed and the expression of modified Sj14 and Sj26 genes could be detected by RT-PCR and IFA. A bivalent membrane-anchored DNA vaccine encoding Sj14 and Sj26 genes was acquired and expressed proteins were proved to be mostly anchored in cellular membranes.

OBJECTIVETo observe the effect of Qubi Recipe (QR) on the expression of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), and hypoxia-inducible factor (HIF)-1alpha in rats with type II collagen-I induced arthritis (CIA), and to explore its therapeutic roles and mechanism.

METHODSTotally 72 male SD rats of SPF grade were recruited. Twelve were randomly selected as the blank control group. The CIA model was established in the rest 60 rats by subcutaneously injecting type II collagen of bovine emulsion from the tail root and induction of incomplete Freund's adjuvant. On day 15 after primary immunization rats were randomly divided into four groups, i.e., the CIA model group, the Tripterygium Glycosides (TG) group (at the daily dose of 9.68 mg/kg body weight), the high dose QR group (at the daily dose of 6.66 g/kg body weight), and the low dose QR group (at the daily dose of 3.33 g/kg body weight), 15 in each group. Corresponding medication was given to rats in all groups by gastrogavage once daily for 4 successive weeks. An equal volume of pure water was given to rats in the blank control group and the CIA model group by gastrogavage, once daily for 4 successive weeks. The swelling degree of the joints was measured. Rats were sacrificed after 4-week treatment. Plasma levels of SOD, MDA, and GSH-Px were measured with colorimetric method. The expression of HIF-1alpha was detected by immunohistochemistry.

RESULTS(1) Compared with the CIA model group, the swelling degree of the joints was significantly alleviated in the TG group and the high dose QR group (P < 0.01, P < 0.05), and it was obviously milder in the high dose QR group than in the TG group (P < 0.05). (2) Compared with the CIA model group, the activities of GSH-Px could be obviously elevated and activities of MDA lowered in the TG group, the high dose QR group, and the low dose QR group (P < 0.05). Plasma activities of SOD could be obviously elevated in the high dose QR group and the TG group (P < 0.05). (3) Compared with the CIA model group, the expression of HIF-1alpha obviously decreased in the TG group and the high dose QR group (P < 0.05), and it showed a decreasing tendency in the low dose QR group with no statistical difference (P > 0.05).

CONCLUSIONSQR could markedly alleviate the swelling degree of ankle joints in CIA model rats. Its therapeutic efficacy was superior to that of TG. Its mechanism might be achieved through down-regulating expression of HIF-1alpha in the joint, and regulating activities of SOD, MDA and GSH-Px in the plasma.

To study the effect of Fuzheng Huayu recipe (FZHY) on five types of isozymes of cytochrome P450 (CYP450) of normal and liver fibrosis rats by using the cocktail probe method. Dimethylnitrosamine ( DMN) was injected to induce the liver fibrosis model. After the tail vein injection with Cocktail probe solutions prepared with five CYP450s probe substrates (phenacetin-CYP1A2, omeprazole-CYP2C9, tolbutamide-CYP2C19, dextromethorphan-CYP2D6, midazolam-CYP3A4), the plasma concentrations of the five probe substrates were determined by LC-MS/MS, and the pharmacokinetic parameters were calculated by PK solutions 2. After the oral administration with FZHY, normal rats given phenacetin, omeprazole, tolbutamide and dextromethorphan showed increase in AUC(0-t) and decrease in CL to varying degrees, indicating that FZHY obviously inhibited the activities of CYP1A2, CYP2C9, CYP2C19 and CYP2D6 in normal rats, but with no obvious effect on the activity of CYP3A4. After the oral administration with FZHY, liver fibrosis rats treated with CYP2C9 showed the significant increase in AUC(0-t) and significant decrease in Vd, hut with no obvious changes in the pharmacokinetic parameters of other four types of prove substances, suggesting that FZHY could significantly inhibit the activity of CYP2C9 in rats but had no effect on the activities of CYP1A2, CYP2C19, CYP2D6 and CYP3A4. The changes in the activity of CYP450 isozymes in liver fibrosis rats may be the reason for FZHY's different effects on CYP450 isozymes in normal and liver fibrosis rats.
