Objective To evaluate the role of radiotherapy in the management of dermatofibrosarcoma protuberans. Methods Between 1995 and 1999, 18 patients with pathologically confirmed dermatofibrosarcoma protuberans were retrospectively analyzed. Nine patients were referred to our hospital for primary treatment and the remaining 9 patients came with recurrent disease. Fifteen of 18 patients received surgery followed by radiotherapy. Among them, 14 patients underwent complete resection and 1 partial resection. Majority of patients received 50～60 ?Gy. One patient received 37.5 ?Gy because he refrained from further treatment. Two patients received 52 ?Gy and 50 ?Gy due to unresectable extensive lesion. One of 18 patients was treated by total resection alone.Results The median of follow up time was 26 months with a range of 0.5～5 years. Sixteen patients (8.9%) are disease free. One patient developed local recurrence and one died of malignant progression. These two patients were treated with radiotherapy alone or surgery only. The local control rates were 100% (15/15) for patients who were treated with surgery and radiotherapy. Conclusions Postoperative radiotherapy is able to decrease the local recurrence rate in dermatofibrosarcoma protuberans.

The personnel training is one of the core tasks of clinical Chinese pharmacy.Since the professional training of clinical Chinese pharmacy has started relatively late in China,the teaching contents and curriculum still need further improvements.This paper is aiming at analyzing the post tasks of personnel of clinical Chinese pharmacy,defining the knowledge structure of them,and learning from the characteristics of clinical Chinese pharmacy teaching systems of the foreign and domestic universities.On such basis,the paper proposes the ideas about constructing the curriculum system of clinical Chinese pharmacy,to provide a reference for the higher educational personnel training of clinical Chinese pharmacy.

The quail model of hyperuricemia combined with abdominal obesity was induced by high purine diet.Body weight in model group showed no change.Serum uric acid level in model group was increased significantly on 7,14,21,and 28 d( P＜0.05 or P＜0.01 ).Abdominal fat index in model group increased significantly on 28d.On 7 d and 28 d,serum free fatty acid level was increased significantly.Acetyl-CoA carboxylase( ACC ) protein expression in the liver of model quail was increased as shown by ELISA and immunohistochemisty ( P＜0.05 or P＜0.01 ),suggesting that the alteration of ACC expression contributes to the pathogenesis of hyperuricemia combined with abdominal obesity.

Objective To study the optimal time of MRI follow-up after transsphenoidal surgery in patients with nonfunctional pituitary macroadenoma. Methods MRI records of 50 patients before surgery,within 1 postoperative week (early stage),at 3 months (intermediate stage) and 1 year after surgery (late stage),respectively,were retrospectively analyzed.Dynamic changes in the sella turcica were observed and the degrees of tumor excision were studied before and after MRI T 1-weighted enhanced scans at different postoperative stages. Results In the early stage MRI images showed that the size of sellar contents decreased by 8%～32%,tumor disappeared in 22 cases,and suspected residual tumor was found in 28 cases.At 3 months after surgery,MRI scans revealed that sellar contents decreased by 11%～85% in size.On coronal position MRI scans,the size of sellar contents decreased more than 50% in 11 cases,30%～50% in 9 cases,less than 30% in 8 cases.Out of the 28 cases that were suspected of residual tumor in the early stage,confirmation of residual tumor in the sella turcica was made in 23 cases.MRI findings 1 year after surgery showed no change in the sella turcica in 46 cases and continuing to decrease in 4 cases. Conclusions Re-examination of MRI in intermediate stage after transsphenoidal surgery in patients with nonfunctional pituitary macroadenoma facilitates the detection of residual tumor and recurrence.

Hyperuricemia is closely associated with abdominal obesity .The prevalence of hyperuricemia combined with abdominal obesity has been increased significantly in recent years , along with the improvement of daily life and the changes in dietary structure .The state of hyperuricemia combined with abdominal obesity is most harmful , and becomes a common and high risk metabolic disease .Animal model with hyperuricemia combined with abdominal obesity is very impor-tant for the research of pathomechanism and treatment of this disease .

In view of the deficiency of traditional teaching methods and teaching resources in clinical practice, our department has designed cases according to diagnosis, diagnosis basis, laboratory examination and treatment, and deploys the case based learning with PPT files according to such teaching process as case introduction, guiding discussion, summary and teaching, introspection and expansion as well as homework. Meanwhile contrast experiment was carried out. The results have showed the case based learning probably has the positive impact on improving teaching quality of clinical practice , mainly reflected in: ①contributing to the completion of the teaching outline;②contributing to the transform of theoretical knowledge from systemic structure to applied structure;③contributing to establishing the teaching model and assessment system which are more complete and standard than the traditional teaching methods; ④contributing to improving students' interest and mo-tivation;⑤contributing to improving the teaching efficiency, which makes students have more time to participate in the application and training of clinical skills.

Background:In the treatment of many gastric diseases,eradication of Helicobacter pylori( Hp)is important. With the increasing in antibiotic resistance of Hp,the eradication efficacy of conventional triple and quadruple therapy for Hp is decreasing in recent years. Aims:To assess the efficacy and safety of quadruple therapy combined with astragalus membranaceus for Hp eradication. Methods:A total of 395 Hp-infected patients with chronic gastritis/dyspepsia and peptic ulcer diagnosed by gastroscopy were enrolled,of them 185 patients were of chronic gastritis/dyspepsia group and 210 patients were of peptic ulcer group. Patients in the two groups were subdivided into trial group and control group. Patients in trial group were given quadruple therapy combined with astragalus membranaceus for 14 days,and patients in control group were given quadruple therapy only for 14 days. Hp eradication was assessed by 13 C-urea breath test 4 weeks after treatment. Results:A total of 358 patients(90. 6%)completed the study. In chronic gastritis/dyspepsia group,the eradication rate was significantly higher in trial group than in control group by PP analysis(P<0. 05),but no significant difference was found by ITT analysis(P>0. 05). In peptic ulcer group,the eradication rates by PP and ITT analysis showed no significant differences between trial group and control group(P>0. 05). In control group,the eradication rates by PP and ITT analysis were significantly higher in peptic ulcer group than in chronic gastritis/dyspepsia group( P <0. 01). In trial group,the eradication rates by PP and ITT analysis were not significantly different between chronic gastritis/dyspepsia group and peptic ulcer group( P >0. 05 ). The incidence of adverse effects was not significantly different between chronic gastritis/dyspepsia group and peptic ulcer group as well as trial group and control group( P>0. 05). Conclusions:Quadruple therapy combined with astragalus membranaceus could increase the eradication rate of Hp in chronic gastritis/dyspepsia group safely.

Knowledge Discovery in Databases is gaining attention and raising new hopes for traditional Chinese medicine (TCM) researchers. It is a useful tool in understanding and deciphering TCM theories. Aiming for a better understanding of Chinese herbal property theory (CHPT), this paper performed an improved association rule learning to analyze semistructured text in the book entitled Shennong's Classic of Materia Medica. The text was firstly annotated and transformed to well-structured multidimensional data. Subsequently, an Apriori algorithm was employed for producing association rules after the sensitivity analysis of parameters. From the confirmed 120 resulting rules that described the intrinsic relationships between herbal property (qi, flavor and their combinations) and herbal efficacy, two novel fundamental principles underlying CHPT were acquired and further elucidated: (1) the many-to-one mapping of herbal efficacy to herbal property; (2) the nonrandom overlap between the related efficacy of qi and flavor. This work provided an innovative knowledge about CHPT, which would be helpful for its modern research.
