A series of methods has been tested successfully for the improvement of targeting to reticuloendothelial system.

Objective To screen and clone the target genes transactivated by nonstructural protein 5A (NS5A) of hepatitis C virus (HCV). Methods The mRNA was isolated from HepG2 cells transfected with pcDNA3.1(-)-NS5A and pcDNA3.1(-) empty vector, respectively. Suppression subtractive hybridization (SSH) method was employed to analyze the differentially expressed DNA sequence between the two groups. The obtained sequences were searched for homologous DNA sequence from GenBank. The new gene with no homology with known genes in this database was confirmed, and electric polymerase chain reaction was conducted for cloning the full-length DNA of the new gene and in conjunction with Kozak rule and the terminus of polyadenyl signal sequence. The reverse transcription PCR (RT-PCR) was used to amplify the new gene from mRNA of HepG2 cell as the template. The coding sequence of the new gene was deduced according to the nucleotide sequence. Results A new gene with unknown function was named as NS5ATP3. The nucleotide sequence of the NS5ATP3 gene and its corresponding amino acid have been determined, which contained 1 572nt and 524aa. The sequence of the NS5ATP3 gene was deposited into GenBank, with the accession number AF529364. Conclusions NS5ATP3 gene transactivated by HCV NS5A protein was cloned and identified successfully by combining molecular biological technology and bioinformatics technique. These results will pave the way for the study of the molecular mechanism of the transactivating effects of HCV NA5A protein and the development of new therapy for chronic hepatitis C.

0.05).The CC10 levels in lung homogenate of the allergic asthma group were significantly decreased than that of control group(P0.05).Conclusion The CC10 levels in lung homogenate is decreased,and has negative correlation with AIPs,which suggests that CC10 may take part in the onset of asthma,and work as an important endogenous anti-inflammatory factor.

Objective To discuss the surgical interference of chronic suppurative otitis media and it's long-term results.Methods In 113 cases of mastoidectomy with tympanoplasty followed up for 3 years,We discuss the results of recurrence and hearing levle of the open-mastoidectomy with tympanoplasty(OMT)and combined approach tympanoplasty(CAT).Results There is no significant difference between OMT(improved 12 dB HL)and CAT(improved 9.5 dB HL)in the improved hearing threshold leve.The recurrence rate of OMT was 5.8%,but the CAT was 24.4%,the difference is significant.Conclusion The effect of OMT is better than that of CAT for the long-term resulls in these cases.

OBJECTIVE:To observe the curative effect of Xiaoer chiqiao qingre granule in treating child common cold fever (stagnant type).METHODS:A total of 118 cases with child common cold fever(stagnant type) were randomly assigned to receive Xiaoer chiqiao qingre granule (treatment group,n=60) or ribovirin tablet,Ertangganmao granule(control group,n=58) tid for 3 days.The antipyretic time, clinical effective rate, and improvement in clinical symptoms were compared between the two groups. RESULTS: There outcome indexes including the antipyretic time,the clinical effective rate,and the improvement in clinical symptoms in the treatment group was significnatly better than in the control group(P

Objective To optimize the extracting process of the mixture of Feining.Methods Orthogonal design was used to optimize extracting process.The content of glycyrrhizicac,Ephedrine and Pseudoephedrin,and the extractive rate of water and n-butyl alcohol were indexes.Results The optimum water-extracting factors were 8 times of water,refluxing and extracting for 1 h,for 2 times.Conclusion The optimal extraction process is precise and repeatable,which can be used in industrial production.

Objective · To extract and identify exosomes in follicular fluid from patients with polycystic ovary syndrome in order to determine the existence of exosomes in follicular fluid, to isolate and extract miRNAs in exosomes, and to detect relative expression of miRNAs. Methods · Exosomes in follicular fluid were collected with membrane affinity chromatography and their size and morphology were observed with the transmission electron microscope. Exosome protein markers CD63 and CD81 were detected with flow cytometry. miRNAs in purified exosomes were extracted and expressions of miR-125b, miR-19b, and miR-222 were measured with TaqMan real-time PCR. Results · Exosomes in follicular fluid were circular or elliptic under the transmission electron microscope with diameters of around 30-100 nm. They had complete membrane structure and contained low density matter. Flow cytometry showed that CD63 and CD81 were positively expressed in exosomes. Real-time PCR detected expressions of miR-125b, miR-19b, and miR-222. Conclusion · Exosomes can be collected in follicular fluid from patients with polycystic ovary syndrome. Transmission electron microscopy and flow cytometry can be used to identify exosomes in follicular fluid. miR-125b, miR-19b, and miR-222 can be detected in exosomes.

Objective To investigate the changes of peroxynitrite(ONOO-)in acute myocardial infarction during ischemia-reper fusion.Methods Thirty patients with actute myocardial infarction(single coronary arterial stenosis of left anterior descending in proximal-middle segment) and twenty-four healthy cases were enrolled as the control in our research.Peripheral blood were taken at the time of 24 h and 72 h after primary percutaneous coronary intervention.The patients were further divided into 2 groups according to their serum cTnI level(mild myocardium injury group with cTnI 0.05).Conclusion Plasma peroxynitrite(ONOO-) is related to myocardium injury during ischemia-reperfusion in actue myocardial infarction which suggest that peroxynitrite may aggravate myocardium injury in acute myocardial infarction during ischemia-reperfusion.

Objective To investigate the the effect of long-term glucocorticoid on bone mineral density (BMD) and bone turnover makers in patients with glomerular diseases. Methods The dual-energy x-ray absorptiometry (DXA) was used to measure the bone mineral density of lumbar spine (L1~L4), femoral neck and trochanter of the 97 patients treated with glucocorticoid and the 20 patients in the control group. In addition , ELISA assay was used to measure the concentrations of bone turnover makers including serum PINP and CTX-I. Results (1)Compared with the control group, the BMD of lumbar spine (L1 ~ L4), femoral neck and trochanter and the concentrations of PINP were significantly lower, while the concentration of CTX-I was increased (P < 0.05);(2) Following up the passage of time and the accumulation of the amount of GC application , the BMD of lumbar spine , femoral neck and trochanter , and the concentrations of PINP decreased , while the concentration of CTX-I steadily increased (P<0.05);(3)Multiple linear regression analysis indicated that the BMD of lumbar spine and trochanter were negatively correlated with the time of GC application (P<0.01),and the concentrations of PINP and CTX-I were correlated with the cumulative doses of GC (r = -0.310 vs 0.221, P < 0.05);(4)The incidence of bone abnormalities in patients received vitamin D and calcium was markedly reduced (P<0.05). Conclusion The long-term glucocorticoid treatment for the patients with glomerular diseases can lead to bone mass reduction or osteoporosis , it can be helpful for early prevention and treatment of glucocorticoid osteoporosis with bone mineral density and bone turnover makers.
