Objective To observe the effect of spleen-strengthening and qi-invigorating prescription(SQP) on serum inflammatory mediators in type 2 diabetes mellitus rats with spleen-qi deficiency syndrome. Methods Rat models were induced by intraperitioneal injection of streptozocin(STZ,30 mg/kg) combined with overstrain,abnormal meals,and greasy foods. Model rats were randomly allocated to three groups:model group was treated with purified water; western medicine(WM) group was treated with aspirin enteric-coated tablet,and traditional Chinese medicine(TCM) group was treated with SQP. And the normal rats were allocated to the normal control group. The course of treatment lasted 6 weeks.Parameters such as fasting blood glucose(FBG),fasting insulin(FINS),C-reactive protein(CRP),interleukin-6(IL-6)and tumor necrosis factor-?(TNF-? ) were measured after treatment,and insulin sensitive index(ISI) was also calculated. Result After treatment for 4 weeks,the above observation indexes were higher in model group than those in the normal control group. In TCM group,the serum levels of FBG,FINS,CRP,IL-6,and TNF-? were significantly lowered,while ISI was increased,and the effect being better than that in the WM group(P

BACKGROUND: How to choose traditional Chinese remedy to treat cerebrovascular disease, not only improving the brain blood supply but also not affecting the blood pressure and heart rate, has been a promising research.OBJECTIVE: To study the role of yangyintongnao granule on average blood pressure and heart rate in anaesthetized dog.DESIGN: Complete grouping design and randomized controlled study based on hybrid dog.SETTING: Department of Anesthesiology, Xijing Hospital, Fourth Military Medical University of Chinese PLA and Department of Pharmacology, Faculty of Preclinical Medicine, Fourth Military Medical University of Chinese PLA MATERIALS: The experiment had finished by Cardiovascular Laboratory of Physiology Department in the Fourth Military Medical University of Chinese PLA from March to June 2003. Totally 23 healthy hybrid dogs in either sex were selected. These dogs were divided randomly into 4 groups: high dose group of yangyintongnao( n = 8), moderate dose group of yangyintongnao ( n = 6), low dose group of yangyintongnao( n = 5) and saline group( n = 4).METHODS: Anesthetic dogs in high, moderate and low dose group of yangyintongnao granule were given different doses of yangyintongnao granule: 2 g/kg, 1 g/kg and 0. 5 g/kg respectively. All doses of drug were calculated based on the body mass of dogs, and the drugs were dissolved in 100 mL saline and given through the gastric canal. Dogs in saline group were perfused with equal saline. Aortic average blood pressure was measured by femoral artery intubation via a piezometric transducer. Heart rate was obtained from R-R intervals of a standard Ⅱ lead of electrocardiograph(ECG). The mean blood pressure and heart rate were recorded 0. 5, 1, 1.5, 2.0,3.0, 4. 0, 5.0, 6. 0 hours after treatment.MEAN OUTCOME MEASURES: The changes of blood pressure and heart rate at different time before and after medication.RESULTS: Totally 29 dogs were brought into the final analysis. Blood pressure: The mean blood pressure was reduced -5.4% to -6. 2% respectively in high dose group and moderate dose group after treatment. But in low dose group the average blood pressure sometimes increased sometimes decreased, mainly decreased. It increased by 6.6% ( P ＞ 0. 05) and decreased by -4. 1% ( P ＞ 0.05) at maximum. The average blood pressure in saline group changed by - 9.6% ( P ＞ 0.05). Heart rate: The heart rate in high and medium dose group gradually reduced as time went on. It reduced by - 4. 4%, - 12.2% and - 9.5% respectively in high, moderate and low doses group. The change in each group was not statistically significant as the same in saline group( P ＞ 0.05).CONCLUSION: Yangyintongnao granule has no significant influence on average blood pressure and heart rate.

?Proliferative diabetic retinopathy ( PDR ) is a group of disease characterized by neovascular disease complication of diabetes mellitus. Neovascular diseases of eye are one of the major causes of blindness of the world. Recent studies showed that vascular endothelial growth factor ( VEGF) and pigment epithelium-derived factor ( PEDF ) are now accepted as the key cytokine in the development of diabetic retinopathy. Recent progress in the investigation of VEGF and PEDF of PDR are summarized in this review.

Objective To establish an accurate method for determining the content of three components in Fufang Buwu Syrup. Methods TLC scanner was selected to detect three components with silica gel G thin layer plate. The sample was separated by using cyclohexane-ethyl acetate-methylenechloride-formic acid (3∶1∶1∶0.2),λS=300 nm. Results The linearity between peak area and ferulic acid was achieved in the range of 0.36-0.84μg, psoralen was achieved in the range of 0.12-0.28 μg, emodin was achieved in the range of 0.01-0.05 μg. The average recovery was 100.7%, 100.8%, 101.0%, and RSD was 1.26%, 1.44%, 1.86%, respectively. Conclusion The method is simple and accurate, which can be used for quality control of Fufang Buwu Syrup.

AIM　To analyze tanshinone IIA in Salvia miltiorrhiza Bunge by supercritical fluid extraction (SFE) coupled with capillary gas chromatography (CGC). METHODS　The solution pressure was predicted by solubility parameter theory, the extraction conditions were confirmed by orthogonal design in which temperature, volume of modifier and dynamic extracting volume had been studied in three levels. RESULTS This method is quick, convenient, precise and accurate, added sample recovery is 95.3%, RSD=4.27%. CONCLUSION　Compared with the method of ultrasonic extraction, significantly better qualitative and quantitative result could be obtained by SFE-CGC and expend less organic solvent then make less pollution.

Objective To analyze the etiology of diabetes ketoacidosis(DKA) in children with type 1 diabetes.Methods Totally 850 person-time of type 1 diabetes children in recent 20 years in our hospital were selected as studied subjects. Two hundred and twenty-five person-time of them were hospitalized because of DKA.Fifty-six cases (131 person-time) were due to recurrent DKA.These patients were classified into 2 groups according to onset time: group 1(diagnosed from 1982 to 1991) and group 2(diagnosed from 1992 to 2001).Results The analysis of recurrent DKA suggested that 71.8 % of them was due to infection, 20.4 % of them did not obey diabetic diet and 9.2 % of them discontinued insulin injection. The etiology of DKA showed no difference in two groups. The number of recurrent DKA in two groups was significantly different (P

Objective To study the diagnosis and treatment of bochdalek′s hernia in children, especially to introduce the methods of repairing the defect of diaphragm using rib-flap and terylene fabric.Methods The diagnosis, misdiagnosis and methods of repairing of diaphragm in 10 cases of bochdalek′s hernia were retrospectively reviewed, and the findings of reconstruction of diaphragm in 2 cases of defect of diaphragm were analyzed.Results All of the 12 cases were misdiagnosed for the first time. Ten cases were cured through abdominal surgery and 2 cases were cured through reconstruction of diaphragm.Conclusions Bochdalek′s hernias in children are lack of specific clinical manifestation and often misdiagnosed before operation. Early surgical treatment is necessary once the diagnosis is established, and the defect of diaphragm should be reconstructed. The repairment of diaphragm using rib-flap and terylene fabric is a practical methods.
