Cytochrome P450 (CYP450) is a key element in the Ganoderma triterpenoid biosynthetic pathway. The catalytic reaction process for CYP450 requires NADPH / NADH for electron transfer. After searching the genome dataset of Ganoderma lucidum, the unique sequence encoding CYP450 and NADPH were discovered, separately. The open reading frames of GLCYP450 and GLNADPH were cloned separately using RT-PCR strategy from G lucidum. The appropriate restriction enzyme cutting sites were introduced at the 5' and 3' ends of gene sequence. The genes of GLCYP450 and GLNADPH were recombined into the yeast expression vector pESC-URA, leading to the formation of the yeast expression plasmid pESC-GLNADPH-GLCYP450. This study provides a foundation for researching Ganoderma triterpene biosynthesis using the approach of synthetic biology.

Objective To construct a luciferase reporter plasmid containing interferon regulatory factor 3(IRF-3)human gene promoter and to evaluate promoter activity in human embryonic kidney(HEK)-293 cells.Methods The 1 000 bp fragment was amplified by PCR with human genomic DNA as a template and was directionally cloned into pGL3-basic multiple cloning sites to construct the luciferase repor-ter plasmid pGL3-pIRF-3.Transfection of HEK-293 cells with the promoter-driven lucife-rase construct was performed to induce lucife-rase gene expression and calculate the relative luciferase activity unit(RLU).Promoter sequence of 1 000 bp upstream of transcription initiation site of IRF-3 was analyzed by using Promoter 2.0 Prediction software.Results DNA sequencing and restriction endonuclease analysis verified the successful construction of the plasmid pGL3-pIRF-3.This IRF-3 promoter exhibited a strong promoter activity with an increase of 42.2-fold of RLU in HEK-293 cells when compared with pGL-3 basic vector.The transfection experiment confirmed that the levels of its activation were significantly higher than that in controls in HEK-293 cells.Function analysis of IRF-3 promoter disclosed seve-ral GATA-1 and specific protein 1(Sp1) sites and E2F in minimal promoter region.Conclusion The plasmid pGL3-pIRF-3 promoter is successfully constructed and has a strong basal promoter activity in HEK-293 cells.

Objective To explore the microcosmic mechanism of pingyangmycin treating infantile proliferating capillary hemangiomas so as to find the optimal method for hemangiomas′ treatment.Methods Sixty samples of infantile proliferating hemangiomas were divided into control group(30 cases,aged from 2 days to 6 months) and experimental group(30 cases,aged from 2 to 6 months).Pingyangmycin was made into emulsion and smeared on the surfaces of the leision in experimental group with 3 times every day as well as only matrix in control group.The specimens were resected on d7,then made into pathological slices and electron microscope slices in order to observe the cells microcosmic structure changes and ultrastructure changes.Furthermore,the apoptotic indexes of two groups were detected by the molecular biology method(TUNEL test).Results The number of apoptotic cells were lower in control group(apoptotic index 18.87?13.67)but higher apparently in experimental group(apoptotic index 29.52?15.33).The difference between two groups was significant(t=2.842 P

BACKGROUND:Some studies have shown that hyperlipidemia can lead to osteoporosis in rats, and exercise can increase the bone mineral density of rats. But the effect of short-time exercise on the bone mineral density of hyperlipdemia induced osteoporosis male rats is unclear yet.
OBJECTIVE:To investigate the effect of short-time middle-load treadmil exercise on the bone mineral density of hyperlipidemia male rats.
METHODS:Twenty-six male Sprague Dawley rats were randomly divided into three groups:control group (n=8), hyperlipidemia group (n=9) and exercise intervention group (n=9). The rats in the control group were fed with normal diet, and the rats in the other two groups were fed with high-fat diet and lasted for 4 weeks to establish the hyperlipidemia models. The rats in the exercise intervention group received treadmil exercise 5 days per week for 4 weeks according to the fol owing schedule:15 m/min for 15 minutes in the 1st week, 15 m/min for 20 minutes in the 2nd week, and then 20 m/min for 20 minutes in the last 2 weeks. Slope grade of the treadmil was adjusted at 0°. At the end of experiment, the rats were sacrificed, and the bone mineral density of the right femur, the morphological change of tibia, the level of plasma alkaline phosphates and calcium content were examined.
RESULTS AND CONCLUSION:Compared with the control group, the distal femur bone mineral density in hyperlipidemia group was significantly decreased (P<0.05);histological analysis of the proximal tibia showed thinning and loss of bony trabeculae arrangement, the gap was widened, and a large amount of fat cel s infiltration or integration into vacuoles in the marrow was observed, the plasma alkaline phosphates was significantly increased (P<0.01). Compared with the hyperlipidemia group, distal femur bone mineral density in the exercise intervention group was increased (P<0.05). After adjust body weight, the whole femur bone mineral density was significantly greater in exercise intervention group compared to hyperlipidemia group (P<0.05). The histological analysis of the proximal tibia showed that the spaces of bone trabeculae decreased and the structure of bone trabeculae compacted, the alkaline phosphates activities were increased (P<0.01). There were no significant differences in serum calcium and phosphates levels between groups. The results show that short-time middle-load treadmil exercise can increase the bone mineral density of hyperlipidemia male rats.

OBJECTIVE:To analyze intervention effect of Drug Rational Usage Guidelines System(DRUGS)on antibacterial agents use in department of obstetrics and gynecology in our hospital. METHODS:The application of antibacterial agents in depart-ment of obstetrics and gynecology in our hospital during Jan.-May(before intervention)and Jun.-Nov. 2012(after intervention)were extracted in respects of drug name,preoperative medication duration,perioperative additional condition,postoperative drug with-drawal time,drug combination,usage and dosage,average hospitalization stay,hospitalization cost. The intervention effects were analyzed. RESULTS:After intervention,the type of antibacterial agents were more in line with national regulations;the proportion of type Ⅰ incision surgery without antibacterial agents increased from 57.8% to 75.2%;the prophylactic application of antibacteri-al agents in type Ⅱ incision surgery within 0.5-2 h increased from 80.2% to 97.0%. The rate of reasonable antibacterial selection, drug combination,usage and dosage increased from 76.9%,64.9%,71.3% to 89.3%,84.6%,90.2%,respectively. The average hospitalization stay and antibacterial cost per capita decreased significantly. There was statistical significance among above indica-tors before and after intervention(P<0.05 or P<0.01). CONCLUSIONS:DRUGS effectively change irrational use of antibacterial agents in department of obstetrics and gynecology,which provide a new method for the management of antibacterial agents.

Objective To study the changes and significance of the frequencies of circulating follicular helper T cells (cTfh) and circulating regulatory follicular T cells (cTfr) as well as the cTfh/cTfr ratio in neuromyelitis optica spectrum disorder (NMOSD).Methods The frequencies of cTfh,cTfr and B cells in patients with NMOSD and health controls(HCs) were measured by flow cytometry.Enzyme-linked immunosorbent assay was used to detect the level of IL-21 and AQP4-Ab in patients and HCs.Results The frequencies of cTfh and B cells,the cTfh/cTfr ratio and the plasma level of IL-21 werc significantly higher in the relapsing patients than those in the remitting patients and HCs(P ＜ 0.05),and the cTfr level in the relapsing patients was lower than that in the remitting patients and healthy population (P ＜ 0.05).But no statistical differences were observed in the above indexes between the remitting paticnts and HCs.There was also no significant difference in AQP4-Ab level between the patients with relapse and remission (P ＞ 0.05).The frequency of cTfh in the patients wasc positively correlated with the level of B cells and IL-21(P ＜ 0.05),and the frequency of cTfr was negatively correlated with B cells and IL-21 (P ＜ 0.05).The ratio of cTfh/cTfr was positively correlated with B cell frequency and IL-21 level (P ＜ 0.05).AQP4-Ab level had no correlation with the frequencies of cTfh cells and B cells,cTfh/cTfr ratio and IL-21 concentration (P ＞ 0.05).Conclusion The changes in the frequencies of cTfh and cTfr as well as the imbalanced cTfh/cTfr ratio may promote the activation of humoral immunein NMOSD and participate in the pathogenesis of this disease.
