  • An Introduction to Methods for Economic Evaluation of Marketed Medicines I: Setting up an Economic Framework and Reviewing Existing Evidence

    Medicine is a very important health resource in China. Although numerous efforts are paid to pre-marketed medicines, little is done to address practical problems in marketed medicines. The rational use and allocation of marketed medicines remain a major concern for decision-makers in China. It has been recognized that economic evaluation is an efficient tool for prioritizing the choice, and optimizing the use of medicines. This paper has explored the methods and principles for conducting economic evaluation of marketed medicines. Different strategies will be adopted for economic evidence for marketed medicines in terms of adequacy and sufficiency.However, a standard study pathway should be applied in economic evaluation of marketed medicines. Besides, the aspects for developing economic framework and the methods for reviewing existing economic evidence are also introduced in this paper, particularly, for marketed medicines within the same therapeutic group.

  • Effect of Tumor Initiating Cells and Epithelial-Mesenchymal Transition in Tumor Metastasis and Drug Resistance

    Objective To summarize the roles of tumor initiating cells (TICs) and epithelial-mesenchymal transition (EMT) in tumor metastasis and drug resistance. Methods Domestic and international publications online which involving TICs,EMT,and its roles in tumor metastasis and drug resistance in recent years were reviewed. Results TICs were self-renewal cells and had the ability to give rise to more differentiated cell types,and played an important role in tumor metastasis and drug resistance. Various markers had been used to identify TICs,such as CD133,CD44,and so on. EMT was the process by which epithelial cells losed polarity and detach from the epithelial sheet, and acquired a motile mesenchymal phenotype,usually observed in embryo development and wound healing. It also could promote tumor progression and metastasis,and may also be responsible for the ability of tumors to evade the body’s immune response. EMT may be the reasons of TICs that drived tumor metastasis and recurrence. TICs or EMT as a target for treatments may effectively prevent tumor recurrence and improve patient’s survival. Conclusions EMT is probably the mechanism that TICs promote tumor metastasis and drug resistance. More effective target therapies for cancer may be found if we know more about TICs and EMT.

  • Acids-Suppressive Drugs and Ventilator-Associated Pneumoni

    为预防应激性溃疡和消化道出血, 质子泵抑制剂( PPI) 、组胺H2 受体拮抗剂( H2 RA) 以及硫糖铝在ICU中的应用非常普遍。既往的研究认为以PPI 或H2RA 为代表的抑酸剂( ASD) 可致胃液pH 值增高, 为细菌在胃腔内定植创造了条件, 并进而增加医院获得性肺炎( HAP) , 尤其是呼吸机相关性肺炎( VAP) 发生的风险。我们通过文献复习发现,ASD 与VAP 的关联性迄今仍无明确的证据, 已有的临床研究结论互为矛盾; 另一方面, 既往研究多集中于硫糖铝与H2RA 的比较, 有关PPI 和H2RA 导致VAP 的风险比较研究仍然缺乏, PPI 是否比H2 RA 更易发生VAP 也缺乏研究可资证明。为此我们将有关内容综述如下, 以供同道参考。

  • Effects of Different Doses of Atorvastatin on Pulmonary Fibrosis of Rats

    Objective To observe the effects of different doses of atorvastatin on bleomycin-induced pulmonary fibrosis in rats. Methods Seventy-five healthy female SD rats were randomly divided into five groups ( 15 rats in each group) , ie. a normal group , a model group, a 10 mg/ kg atorvastatin-treated group, a 20 mg/ kg atorvastatin-treated group, and a 40 mg/ kg atorvastatin-treated group. The rats in the model group and treatment groups were instilled with bleomycin in trachea( 5 mg/kg) , and the normal group were instilled with equal volume of normal saline. The treatment groups were gastric gavaged with different doses of atorvastatin each day from2 nd day on after instillation, and the normal group and model group were gavaged with normal saline. Blood samples were obtained from abdominal aorta in five rats in each group and blood gas analysis was performed on1st week, 2nd week and 4th week respectively after BLM instillation. Then the animals were killed and lung tissue samples were harvested for histopathology study. HE and Masson staining were used to determine the extent of alveolus inflammation and pulmonary fibrosis respectively.Histoimmunochemical stain were used to determine the protein levels of transforming growth factor-β1 ( TGF-β1 ) and connective tissue growth factor( CTGF) in pulmonary tissues. Results The arterial partial pressure of oxygenate ( PaO2 ) in the treatment groups were increased gradually with the increasing of therapeutic dose at each time point and decreased with prolongation of time in the same group. The protein levels of TGF-β1 and CTGF in pulmonary tissues were decreased gradually with prolongation of time. TGF-β1 and CTGF expressed obviously less in the treatment groups than those in the model group at each time point .The higher therapeutic doses were, the less the expressions of TGF-β1 and CTGF were. Conclusion Atorvastatin has remarkable inhibitory effects on BLM-induced pulmonary fibrosis of rats in a dose- and timedependentmanner.
