Retreatment of hepatitis C patients with pegylated interferon combined with ribavirin in non-responders to interferon plus ribavirin. Is it different in real life?

Background  

More than 50% of hepatitis C viruses (HCV)-infected patients do not respond to the classical Interferon (IFN)/Ribavirin (RBV) combination therapy. The aim of this study was to evaluate the efficacy of retreatment with Peg-Interferon alpha-2b (PEG-IFN alpha-2b) plus RBV, in patients with HCV, genotypes 1 or 3, who were non-responders to the previous standard treatment with IFN/RBV.

Local therapy in endometrial cancer: evidence based review

KEY POINTS: (1) Surgery is the standard primary treatment for early stage endometrial cancer, with local adjuvant therapies such as pelvic radiotherapy and vaginal brachytherapy most often used in patients with high risk of recurrence. (2) There are currently very few well designed studies evaluating local therapies in endometrial cancer. (3) To date, the available evidence suggests that adjuvant external beam radiotherapy reduces locoregional recurrence in stage I disease but not the risk of death. Considering the high survival rate and low recurrence risk of patients with early stage disease, postoperative adjuvant radiotherapy should perhaps be limited to patients with high risk of recurrence, particularly since such radiotherapy is associated with increased long-term complications and toxicity. (4) Adjunctive chemotherapy has so far failed to demonstrate any improvement over radiotherapy in terms of overall survival in patients with intermediate and high-risk endometrial cancer. (5) Further well controlled studies are required in order to confidently establish the optimal use of local treatments and other therapies in endometrial cancer.     

高效液相色谱法测定消痰咳片的含量

目的：采用反相色谱法同时测定消痰咳片中两种主要成分甲氧苄啶和磺胺体的含量。方法：以乙腈：0.1%H3PO4(15:85)为流动相，检测波长254nm，HPLC法测定含量。结果：试验表明，甲氧苄啶和磺胺林在0.8-8ug范围内呈良好的线性关系，回归方程分别为Y＝－1127.1＋110.2x(r=0.9994),Y=-1852.3 256.2x(r=0.9996),相对标准偏差分别为2.1%和0.8%。结论：该方法简便、准确、可靠。
