Biotech is currently the fastest growing sector in drug industry. Globally biotech products generated revenues of $55bn in 2004, in a total drug market worth $550bn. The USA is the primary market of biotech products, being the source of approximately half of sales in 2004. About 55% of biopharmaceuticals’ sales in 2004 came from the five leading products (Erythropoietin,Interferon,Human insulin,G-CSF,Rituximab).Great progress has been made in the biotech market of China over the last few years. About 60%~70% of recombinant protein biopharmaceuticals are expressed in mammalian cells in USA and EU, while most recombinant protein biopharmaceuticals are expressed in E.coli in China. Most biopharmaceuticals expressed in mammalian cell can’t be manufactured in China. The biotech industry comprise numerous, mostly small organizations. These organizations typically employ less than 100 people. Most biotech companies have never brought a product to market before they disappear. Therefore, it is very important for biotech companies to make an appropriate development strategy.

Objective To investigate the changes and clinical significance of serum procalcitonin (PCT) level in children with acute phase of Kawasaki disease (KD). Methods The serum PCT levels and their changes before and after the treatment in 120 children with KD at acute phase were retrospectively analyzed. According to the results of ultrasonic echocardiography, all children were divided into coronary artery damage (CAL) group and no coronary artery lesion (NCAL) group. According to the presence of gastrointestinal symptoms, patients were divided into two groups (A: yes and B: no ). According to the presence of abnormal liver function, patients were divided into two groups (C:yes and D:no). PCT levels were compared between groups. Results The serum PCT levels were increased at acute phase in 56 (46.67%) patients before the treatment than those in normal children, which were decreased obviously after treatment (P<0.05). There were 31 cases combined with CAL, the rising rate of PCT was 38.71%, which was no significant difference compared with that of NCAL group (49.44%, P>0.05). There was no significant difference in serum PCT value between CAL group and NCAL group (P>0.05). The serum C-reactive protein level was significantly higher in CAL group than that of NCAL group. There were 35 patients combined with gastrointestinal symptoms in 120 KD patients. There was no significant difference in the rising rate of PCT between patients with gastrointestinal symptoms (62.86%) and patients without gastrointestinal symptoms (40.00%, P<0.05). There was no significant difference in serum PCT level between these two groups of patients. There were 42 cases with liver dyfunction in 120 KD patients, the PCT rising rate (52.38%) was no statistically significant difference compared with that of patients with no liver dyfunction (43.59%, P>0.05). And there was no significant difference in serum PCT value between the two groups (P>0.05). Conclusion PCT can reflect the acute phase of KD patients. The increased PCT level may be related with the emergence of gastrointestinal symptoms, even though it cannot predict CAL and the occurrence of liver damage.

Objective To explore the influence of blocking B7/CD28 co-stimulatory pathway by RNA interference on the rejection response in mice heterogeneous heart transplantation and its mecha- nism.Methods siRNA of which sequence specified to CD80 and CD86mRNA was synthesized in vitro respectively and transfected into donor derived myeloid dendritic cells (DCs).The expression levels of CD80 and CD86 mRNA and surface antigen CD80,CD86 were assayed by semi-quantitative reverse transcription polymerase chain reaction and flow cytometry before and after CD80siRNA and CD86siRNA transfection.Seven days prior to heterogeneous heart transplantation in mice,DCs modi- fied by siRNA were transfused into recipients intraveneously (DC interference group).At the same time,group of allograft transplantation,cyclosporine A (CsA)-treated (CsA injected subcutaneously postoperatively,5 mg.kg~(-1)?d~(-1)) group,group of isograft transplantation,and non-interference DC group (transfusion of non-interfered DCs pre-transplanting) were assigned.The graft survivals were individually recorded and the graft rejection grading was pathologically evaluated.Interleukin 2 (IL- 2),interferon?(IFN-?),and IL-10 mRNA expression levels in grafts tissue were determined.Results After siRNA transfected into DC,the expression levels of CD80 and CD86 mRNA were down- regulated significantly and the the antigen CD80~+ and CD86~+ reduced from 84%,67% to 35% and 30% respectively.As compared with groups of allograft and non-interference DC,survival of the grafts was significantly longer in DC interference group (P＜0.01),pathological grade of rejection significantly lower (P＜0.01),IL-2 and IFN-?mRNA expression levels lower,and IL-10 mRNA ex- pression levels higher in grafts tissue (P＜0.01).Conclusion Knocking down the molecule B7 expres- sion level in donor-derived myeloid DCs through RNAi,which could block B7/CD28 co-stimulatory pathway,could exhibit inhibitive effect on rejection response in mice heart transplantation.The mechanism might be due to induction of T lymphocyte anergy and Th cell differentiation deviating to T_H2.
