Objective: To establish the quality standard for Ganmaoyangkeling Tablets(Radix Isatidis, Herba Solidaginis, Radix Glycyrrhizae, Rhizoma Zingiberis Recens, etc.). Methods: Radix Glycyrrhizae and Herba Solidaginis were identified by TLC, and the content of quercetinum was determined by HPLC. Results: Quercetinum shows a good linear relationship in the range of 0.05～0.40?g ( r =0.99997), and the average recovery is 101.9%, RSD is 2.07%. Conclusion: These methods is simple, accurate and specific and can be used for the quality control of Ganmaoyangkeling Tablets.

It is the requirement to change the utility reading of medical undergraduates and to realize the functions of medical academic library for medical academic library to popularize reading service .The serial reading populari-zation service practice was thus described in this paper with certain feasible suggestions put forward for the further reading popularization activities.

Objective To investigate the characteristics of mesenteric vascular thrombosis (MVT) in patients with antiphospholipid antibody syndrome (APS).Methods The cases reports about MVT in patients with APS were searched in Pubmed and Chinese biomedical database (1983.1-2007.7) and then were analyzed.Results There were 13 males and 8 females in 21 patients.The average age was (37±17) years (5months～69 years).Three cases (14%) had a history of deep venous thrombosis and 4 (19%) had spontaneous abortions.The course of disease was 4 hours to 4 months.The clinical manifestations included abdominal pain 18 (86%),hemafecia or melaena 4 (19%),vomiting 3 (14%),diarrhea 2 (10%),hematemesis 2(10%).Physical signs included abdominal tenderness in 10(48%),peritoneal irritation signs in 5 (24%),shifting dullness in 3 (14%) anddecreased bowel sounds in 3 (14%).Mesenteric vascular thrombosis were detected through B uhrasonography (3/10,33%),abdominal CT (9/13,69%),MRI (4/4,100%),Doppler ultrasound (4/4,100%),angiography (6/6,100%).Eighteen cases (86%) had positive anti-cardiophospholipin antibody and 14 (67%) were IgG-subtype.Lupus anticoagulants were detected in 4 (19%).Sixteen cases reee-ived exploratory laparotomy,lsehemia or necrosis of intestine were found in 9(56%).In 21 cases,superior mesenteric vein thrombosis,suprior mesenteric artery thrombosis,inferior mesenteric vein thrombosis,inferior mesenteric artery thrombosis were discovered in 17 (81%),4 (19%),0 (0%),1 (5%)patients respectively.Portal vein was also involved in 7 (33%) cases who had superior mesenteric vein thrombosis.Conclusion Superior mesenteric vein is usually involved in patients with APS who have MVT.MVTs are always occurr in middle-age male patients.Some patients have deep vein thrombosis or spontaneous abortion before MVT.The disease may be fulminant or had is insidious in onset.Abdominal pain and intestinal obstruction are the most common manifestations.IgG-subtype anticardiophospholipin antibodiesare the common antibodies discovered in these patients.Combined more than one image methods can detect the thrombi effectively.Anticoagulation and essential exploratory laparotomy are effective interventions in most cases.

Objective The objective of this study is to describe the clinical features and outcomes of connective tissue disease (CTD) patients with mycophenolate mofetil (MMF) and with Pneumocystis jirovecii pneumonia (PJP).Methods We retrospectively reviewed the characteristics,clinical features,treatment and outcomes of PJP in patients with CTD.The clinical variables were compared between groups using t-test.Results ① A total of 17 cases were reviewed.② Sixteen patients were treated with glucocorticoids(GCs) plus immunosuppressive drugs.Only one patient had GCs without immunosuppressive drugs.Sixteen patients were with PJP,10 (63％) patients had MMF.③ Ten MMF patients and 7 non-MMF patients had absolute lymphocyte counts with the average being (557±170)/` and (926±162)/μl,respectively (t=-4.481,P＜0.05).④ Six of 17 patients died during the hospitalization.Five patients of 10 patients with MMF died 1 of 7 patients without MMF died.Fifteen of 17 patients were treated by trimethoprim-sulfamethoxazole (TMP-SMX).Conclusion MMF may be risk factors of PJP in CTD.

Objective To study relationship of expression of Survivin and cyclooxygenase(COX)-2 in the tissue of non-small cell lung cancer (NSCLC) with differentiation, lymph node metastasis and clinical stage. Method The expression of Survivin and COX-2 were detected by immunohistochemical SP staining in the specimens of 43 cases of NSCLC and 20 cases of para-cancerous lung tissue. Results The positive rate of Survivin and COX-2 was 67.4% (29/43) and 55.8% (24/43) respectively in NSCLC,was 0 respectively in the para-cancerous lung tissue. Compared with para-cancerous lung tissue,there was statistically significant difference(P< 0.01). Both Survivin and COX-2 had significantly higher expression in NSCLC with poor differentiation,lymph node metastasis and clinical stage of Ⅱ-Ⅲ than those with well differentiation,without metastasis and clinical stage of Ⅰ (P <0.05). Conclusion The expression of Survivin and COX-2 are high in NSCLC,they both have relationship with differentiation,lymph node metastasis and clinical stage of NSCLC.

This study revealed that the content of intra and extracellular polysaccharides may be related to the cultural conditions.With decreasing NaHCO 3 or NaNO 3 concentration,the content of intracellular polysaccharide was reduced,Reduction of NaNO 3 concentration still caused the rise of extracellular polysaccharides.The K 2HPO 4 or NaCl concentration also had an effect on the production of both intracellular and extracellular polysaccharides.When PH value of media maintained at 8.0,there was the highest content of intra and extracellular polysaccharides.The same high content also occurred after culture of nine days.In addition the content of intracellular polysaccharide was higher under continuous light than under the light/dark circle.

By using electron microscopy histochemical method, light microscopy histochemical method and microspectrophoto meter, we studied the ACP activity of the principal cell of epididymal duct in the postnatal 10-90 days rats. The results revealed that ACP activity increased with the increase days. We also observed the following phenomena: in the postnatal 10 days rats the ACP activity was only localized on GERL and vesicles around GERL; by in the postnatal 19 days rats, the ACP activity was localized on lysosome; and 35 days later, the ACP was also localized on the saccules on the forming face of Golgi complex. The significance of the above changes in ACP activity of the principal cell of epididymal duct in postnatal rats was discussed in this paper.

Based on the construction and its rational theories of Habermas's living-world,this paper analyzes the characteristics of plague and adjusts them according to Chinese social framework and realistic conditions during plagues.The social rescuing system and its sociological rational evolution style are also analyzed based on the functional framework of government,social culture and individuals.Individual's life style and behaviors have both been adjusted due to high pressures of plagues and government's standardization and interferences to the plagues.But seen in the long run,rational evolution of individual's life style depends on the accumulation of time,civilization,and the recognition of medical ethics among general public.
