OBJECTIVE: To provide references for the establishment of academic promotion mode in domestic pharmaceutical enterprises. METHODS: The advantage and disadvantages of two chief academic promotion modes were analyzed,and the key points in the the plan for the the academic promotion were exounded. RESULTS & CONCLUSIONS: The self-construction of enterprises and academic promotion outsourcing have their own advantages and disadvantages. Suitable orientation of products and definite product promotion information,the definition of audiences for the promotion,alignment of promotion activity with market orientation,the adaptation of promotion activity to product cycle etc were the keys in making the academic promotion plan. Under the new situation,establishing academic promotion mode suitable for the development of the enterprises is indispensable for the promotion of marketing of prescription drugs.

Objective To explore the value of serum SC5b-9, anti-C1q antibody, C3 and C4 levels in the assessment of lupus activity. Methods The enzyme linked immunosorbent assay (ELISA) was used to measure SC5b-9 and anti-C1q antibody, rate nepheiometry was used to detect the serum level of C3 and C4 in sera of 62 SLE patients, 35 patients with other rheumatic diseases (including rheumatoid arthritis, ankylosing spondylitis, primary Sjogren' s syndrome, mixed connective tissue disease, dermatomyositis, polymyositis, systemic sclerosis and vasculitis) and 35 healthy controls. And the correlation between above-mentioned parameters and lupus clinical manifestations, disease activity and histological type of lupus nephritis were analyzed. Results In SLE patients, the levels of SC5b-9 and anti-C1q antibody were significantly higher than those in patients with other rheumatic diseases and healthy controls (P<0.05). The titers of SC5b-9 and anti-C1q antibody negatively correlated with C3 and C4 (P<0.05), and positively correlated with SLEDAI (P<0.05). The sensitivity and specificity of the combination of these three measurements for SLE was 95.37% and 98.46 respectively. SC5b-9 and anti-C1q antibody were associated with the presence of proliferative glomerulonephritis (P <0.05). Conclusion Taking the evaluation of all these three measurements simultaneously is valuable for the diagnosis of lupus flare. SC5b-9 and anti-C1q antibody may play major roles in the immunopathogenesis of lupus nephritis.

Objective To analyze the genotype distribution of human papillomavirus( HPV) strains and their epidemiological characteristics in cervixes of Chinese females. Methods Pertinent litera-tures published during 2004 to 2013 were screened from PubMed,China National Knowledge Infrastructure (CNKI)and Wanfang database for data analysis. Results There were 245 studies screened out for the me-ta-analysis. A total of 661 658 cases met the inclusion criteria,ranging from 16 to 87 years old. All prov-inces and territories of China were covered by the data. The overall rate of HPV infection in cervix was 25. 0% among Chinese females. The predominant high risk genotype of human papillomavirus strains was HPV16,followed by HPV52,HPV58,HPV18,HPV33 and HPV31. HPV52 and HPV58 genotypes were more prevalent than HPV18 genotype. HPV35 and HPV45 genotypes were less popular. Conclusion The study suggested that the HPV infection showed obvious regional differences in genotypes. The genotype dis-tribution of HPV infection in China was different from that in other regions of the world. There were differ-ences with genotype distribution of HPV strains among seven geographic regions of China.

Objective To compare the traumatic indicators of complete video-assisted thoracoscopic surgery (c-VATS) with traditional open surgery (TOS) for lung cancer patients, and further explore the minimal invasiveness of c-VATS. Methods From January 2010 to February 2013, 45 cases with complete video-assisted thoracoscopic surgery (c-VATS gurop) and 42 cases with traditional open surgery (TOS group) were compared in operation time, intraoperative blood loss, duration of chest drainage, the perioperative cytokine and immune cells (CRP,WBC,N,L),pain score and shoulder function score. Results There was no significant difference between groups in sex, age, pathological type, stage,operating time and the perioperative cytokine and immune cells (CRP, WBC, N, L) ( >0.05);Compared with TOS group, c-VATS group intraoperative blood loss was significantly reduced [(167.4±68.5) mL vs (288.6±84.0) mL, =0.000];Drainage time of TOS group was significantly longer than that of c-VATS group [(4.64±2.10) days vs (3.20±1.20) days, =0.000];The postoperative pain measurements in c-VATS group were less than that in TOS group, but the difference between groups was not significant on postoperative 1 day ( =0.542) and significant on postoperative 3 day,7 day,30 day ( = 0.034, 0.000, 0.000) . Patients activities of daily living scores at postoperative 7 day and 30 day in c-VATS group were significantly better than those in TOS group, with statistically significant differences ( =0.000,0.000) . Conclusion Whether the short-term effect or the long-term results,the VATS lung resection is better than the traditional open surgery. c-VATS resection of lung cancer is more invasive.

Objective To explore the expression of P53 and mettl-9 gene in colon cancer tissues and inflammation tissues and normal adjacent tissues and study its relationship with colon cancer.Methods The morphologic situation of histiocyte after H.E.stained was observed.The real-time fluorescent quantitative PCR was applied to detect the gene expression of P53 and METFL-9.Results The expression of P53 gene in inflammation tissues was significantly higher than that in cancer tissues and adjacent tissues(P ＜0.05).The expression of P53 gene in cancer tissues was significantly lower than adjacent tissues and infiammation tissues.METTL-9 gene expression in inflammation tissues was significantly lower than cancer tissues and adjacent tissues(P ＜0.05).In cancer tissues,P53 gene and METFL-9 gene were negative related.Conclusions The mutations of P53 gene played an important role in the course of colon cancer,its downstream gene METTL-9 was highly expressed in colon cancer,and the 9-methyl-converting enzyme which produced by transcription and translation might lead gene hypermethylation in the colon cancer,and thereby promoted the development of colon cancer.

Objective To evaluate the immunogenicity of group A and C meningococcal polysaccharides conjugates using different proteins as carriers. Methods Heat-labile enterotoxin B subunit (LTB)pentamer form was expressed in E. coli. The target protein was identified and purified by cation-exchange chromatography. Then biological activity of rLTB was tested using GM1-ELISA. GCMP was conjugated to rLTB with the chemical method (ADH). Furthermore, the mice were immunized with GAMp-TT/GCMP-TT conjugates and GAMP-TT/GCMP-rLTB conjugates via peritoneal. Finally the anti-polysaccharide antibody was detected. Results The GAMP-TT/GCMP-rLTB conjugate elicits remarkably higher serum antibodies in mice than GAMP-TT/GCMP-TT conjugate. Conclusion These results indicated that polysaccharide conjugates using different proteins as carriers were superior to those using only one protein as carrier.

Objective To evaluate the immune effects of virus-like particles ( VLPs) of VP1 pro-teins derived from norovirus GⅠ. 1 and GⅡ. 4 genotypes expressed in Hansenula polymorpha expression sys-tem. Methods SDS-PAGE and Western blot assay were performed to detect the purity of GⅠ. 1 and GⅡ. 4 VP1 proteins after purification. Morphologies of the recombinant VLPs were observed under transmission electron microscopy ( TEM) . Sizes and distributions of the VLPs were analyzed by dynamic light scattering analyzer. BT50(50% of blocking titer) was detected by HBGA (histo-blood group antigen) blocking assay in BALB/c mice immunized with different regimens. Results SDS-PAGE analysis of the purified recombinant GⅠ. 1 and GⅡ. 4 VP1 proteins showed that their purity were greater than 90%. Western blot assay con-firmed the specific bands of VLPs. TEM images showed that the sizes of purified GⅠ. 1 and GⅡ. 4 VP1 VLPs were at a mean diameter of 30-50 nm with clear border and high homogeneity, which was similar to that of wild virus. BT50 significantly increased in the groups, in which Al( OH) 3 was used as adjuvant. Con-clusion Animal studies have shown that administration of GⅠ. 1 and GⅡ. 4 VP1 VLPs in the presence of Al( OH) 3 induces detectable HBGA-blocking antibody, indicating that GⅠ. 1 and GⅡ. 4 VP1 VLPs are promising candidates for norovirus vaccine.

Objective To evaluate clinical efficiency and quality-of-life outcomes in treatment of severe pelvic organ prolapse by the Xiehe pelvic floor reconstruction surgery. Methods From Jun. 2006 to Dec. 2008, 277 severe pelvic organ prolapse patients with stage Ⅲ to Ⅳ from 8 hospitals in China were enrolled in this prospective study. Pelvic organ prolapse quantitative examination (POP-Q) and anatomic improvement in these patients after surgery were analyzed in this interim study. Comparisons of pelvic floor impact questionnaire-short form 7 (PFIQ-7) and pelvic floor distress inventory-short form 20 (PFDI-20) in these patients before and after surgery was used to evaluate quality of life. Comparison of pelvic organ prolapse-urinary incontinence sexual questionnaire (PISQ) in these patients before and after surgery was used to evaluate quality of sexual life. Results With a median follow-up of 14. 0 months (6 -28 months),twenty-three patients showed recurrent prolapse (8. 3%, 23/277), and anatomical success ( ＜ stage 2 in the treated compartment) was 91.7% (254/277). In this series, mesh exposure or erosion rate was 6. 9% (19/277). The postoperative de novo stress incontinence rate was 6. 5% (18/277). The scores for PFIQ-7 and PFDI-20, and its subscales were significantly improved, the scores of before treatment were lower than those after treatment (P ＜0. 01 ). And there was no significant difference in the average score of PISQ before and after the surgery (76. 6 ± 15.4 versus 75.5 ± 14. 5 versus 73.6 ± 12. 6, P ＞0. 05 ), but the rate of de novo dyspareunia was 11% (9/80). Conclusions Xiehe pelvic floor reconstruction surgery was safe and efficacy in treatment of pelvic organ prolapse. It could improve quality of life remarkably with less cost when compared with the traditional total pelvic floor reconstruction surgery.

Objective To analyze the genome sequencing of mumps virus strain 79 purified from working seeds plague and examine its phylogenetic relationship with wild type virus strain isolated in China,and to explore the efficacy of vaccine at molecular level.Methods Whole genome sequences of two substrains of S79(major and minor),were obtained with fragment amplification by RT-PCR.Genetic distances between S79 and strains identified in China were analyzed based on the phylogenic analysis of small hydrophobic protein(SH) sequences.Results The nucleotide homologies of two S79 substrains(major and minor),with a ratio of 2:5 during culture,with Jeryl Lynn(JL) strain were 99.7% and 100%,respectively.There were scattered non-homologous recombination between two substrains.The genetic distances between strain S79,which was genotype A,and wild type virus strain identified in China,which were genotype F,was 11.2% -20.0%.S79 live vaccine was composed of two substrains,major and minor component,which were highly similar to JL strain in their genome sequences,but different from JL in their ratios during culture.Conclusion Different from wild type virus strain identified in China,the genotype of S79 was A,and phylogenetically distant from other strains,which may account for the low efficacy of S79 live vaccine.The ratios of two substrains might also be of interest for further study of the vaccine protection and efficacy.

OBJECTIVETo analyze CYP21A2 gene mutation in two families with 21-hydroxylase deficiency (21-OHD) and to explore the correlation between genotype and clinical phenotype.

METHODSTwo patients with 21-OHD and their families were investigated. CYP21A2 gene mutation was analyzed by PCR and direct sequencing.

RESULTSThe probands from family 1 and 2 have been respectively diagnosed with simple virilizing and non-classical 21-OHD. Both showed increased baseline serum 17hydroxyprogesterone, testosterone and adrenocorticotropic hormone (ACTH), but had no evidence of salt loss. Computer tomography revealed bilateral adrenal hyperplasia in both patients. After 1 year treatment, both had conceived successfully. DNA sequencing revealed that the proband of family 1 had compound heterozygous mutations for IVS2 13 A>G and Ile172Asn. Her father was heterozygous for Ile172Asn, whilst her mother and brother were heterozygous for IVS213A/C>G. In family 2, the proband was heterozygous for Arg341Trp and Gln318X. Her father, sister and nephew were heterozygous for Arg341Trp, whilst her mother was heterozygous for Gln318X. her brother and niece were non-affected. Carriers of single heterozygous mutations in both families had no clinical sign.

CONCLUSIONIn both families, the disease has been caused by compound heterozygous mutations, for which there has been a good genotype-phenotype agreement. Screening of CYP21A2 gene can facilitate both diagnosis and genetic counseling.
