OBJECTIVE:To investigate the quality differences of Betamethasone tablet from different enterprises,and provide reference for the eventual establishment of the drug relative quality evaluation system. METHODS:According to the principle and steps of the ideal point method,a mathematical model was established. And the perfect point of the 3 inspection parameters (content,content uniformity and dissolution)of Betamethasone tablet was regarded as the upper limit theoretically,and the permis-sible point as the prescribed minimum in the model. After homogenizing the initial data or ones to be quantifiable were translated in-to evaluation parameters;and the evaluation parameters were calculated by ideal point method to receive comprehensive evaluation results. RESULTS:According to variance analysis,there was no significant difference in the comprehensive evaluation results of Betamethasone tablet from different enterprises(P=0.54>0.05),indicating that the overall quality of Betamehasone tablet was good. CONCLUSIONS:The mathematical model of quality evaluation with different drug has certain feasibility and operability.

Neoadjuvant therapy has become an indispensable part of the treatment in locally advanced mild-low rectal cancer. Neoadjuvant therapy can cause the regression of the tumor body as well as drainage lymph nodes, which may influence the size, number, and metastatic status of the lymph nodes. In clinical practice, the total number of lymph nodes detected in rectal cancer treated with neoadjuvant therapy were significantly decreased, making it difficult to meet the standard of the NCCN guideline that at least 12 regional lymph nodes should be harvested. The optimal detection of yielded lymph nodes in rectal cancer is essential for accurate staging, response assessment, and adjuvant treatment decision. The lymph node diameter is significantly reduced after neoadjuvant therapy in locally advanced rectal cancer. In general, the number of detected lymph nodes is significantly reduced without additional pathological examination. The detected lymph nodes would increase by deliberate pathological examination, improvement of the detection method, or using a lymph node tracer. However, whether the number of detected lymph nodes is still needed to meet the requirements of the NCCN guideline, and the relationship between the number of detected lymph nodes and the prognosis are still controversial. At present, the number of negative lymph nodes, LNR, LODDS, etc. can be also used to predict prognosis in addition to ypN staging. For patients with ypN0 and ypN+ stage, different evaluation methods can be selected. For patients with ypN0, the number of detected lymph nodes still has important clinical significance for the prognosis and treatment decision. This article will introduce the related issues, and provide more evidence-based diagnosis and treatment practice.

Objective To investigate the most appropriate surgical methods,different surgical modes of osmidrosis and their clinical effi-cacy were observed. Methods Clinical data was collected from 200 cases of axillary osmidrosis from January 2011 to July 2013. These cases were divided into four groups of the traditional group,minimally invasive group,RF pen-frequency electric cautery group and improved curet-tage group. Results The traditional group(80 cases) has an average healing period of 18. 7 days for operative incision including 78 cured cases(97. 5%)and 2 significant improved cases(2. 5%). The minimally invasive group(60 cases)has an average healing time of 8. 6 days, among which there are 3 cured cases(5%),8 significant improved cases(13. 3%),16 improved cases(26. 7%),4 cases(6. 7%)with weak curative effect and 29 failed cases(48. 3%). In the RF pen-frequency electric cautery group(30 cases),there are 5 significant improved ca-ses(16.7%),8improvedcases(26.7%)and17failedcases(56.6%).Theimprovedcurettagegroup(30cases)withanaverageincision healingtimeof9.8dayscontains28curedcases(93.3%)and2significantimprovedcases(6.7%). Conclusion Thetraditionalgroup shows the best curative effect,nevertheless the incision needs a considerably amount of time to recover. The patients under the treatment of minimally invasive surgery or RF pen-frequency electric cautery can recover in short time but recrudescence always occur. The improved cu-rettage method,which is effective and safe,combines the advantages of traditional surgery and minimally invasive surgery. However,large scar left from this method still remains as its major disadvantage but the overall curative effect is satisfactory. The improved curettage is proved to be the most appropriate method for axillary osmidrosis.
