Diabetic microvascular disease is a severe complication of diabetes mellitus (DM).There are many hypoth-esis for its mechanisms.This overview aimed at effect of C-peptide,coagulant factors,platelet and D-dimer in dia-betic microvascular disease,and provided evidence for its prevention and treatment in clinic.

Objective To understand change and pathogenesis of microalbuminuria(MAU) in cases of adiposity.Method MAU were measured by immunoturbidmetric methods 300 cases of adiposity and 100 cases of nomal children in morning,meanwhile blood press,blood su-gar,blood fat,blood insulin were measured.Results MAU was higher in cases of middle and severe adiposity than normal controls.The diffe-rence was significant(Pa

Objective To observe the mammographic appearance of accessory breast tissue in the axilla. Methods In the past 3 years, 7 562 women were underwent bilateral screen-film mammography. All of the mediolateral oblique(MLO) films were reviewed retrospectively to look for whether there was accessory breast tissue and what the mammographic features were like. Radiographically the accessory tissue resembled the main normal breast glandular tissue but was separated from it. Results Of the 7562 cases, accessory breast tissue in the axilla was detected in 161 cases. The prevalence was 2%. The age ranged from 17 to 70 years (mean, 39 years). 38% of them were found in the bilateral axilla, 42% only in the right, and 20% only in the left. The dimensions on the right ranged from 0.7 to 8.0 cm (mean, 3.5 cm), and that on the left ranged from 1.0 to 7.0 cm (mean, 3.3 cm). There were four types among the accessory breast tissue: patchy type was the most (35%), then the branched type(26%),mixed type(20%), and mass-like type(19%). 3 cases were proved by pathology. Conclusion It is important that the radiologist be familiar with the mammographic appearance of accessory breast tissue in the axilla in order that they could be distinguished from other pathological changes.

The importance and necessity of undergraduates participating in the training plan of the medical research was clarified.Based on the actual ability of students and the characteristic of experimental teaching plan,we think that combination of experimental teaching of small group with research training is a strategy for enhancing the ability of the medical undergraduates to do research.This proposal will speed up the medical educational goal by the activation of novel idea,the cultivation of innovatory thought and the enhancement of creative ability.

0.05).Conclusion Long-term inhaled glucocorticosteroids has no obvious effect on GH and height growth of asthmatic children.

Objective To explore the diagnosis value of cystatin C(Cyst-C) level on the renal function early impairment of Henoch-Schonlein purpura(HSP).Methods The selected serum creatinine(SCr) normal 45 sufferers,with measured their urine routine analysis,and the same time did serum Cyst-C.Compared with 30 healthy children of serum Cyst-C.Results The levels of serum Cyst-C in HSP were definitely higher than those in healthy group,and the differences were together with its signifincance(P

Aim To investigate effects of 1,25-(OH)2D3 on the differentiation of MGC-803 cells.Methods MGC-803 cells were treated by 1,25-(OH)2D3(10-6、10-5、10-4 mmol?L-1),and the rate of growth suppression was evaluated by 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl tetrazolium bromide(MTT) assay.Plate clone formation assay was carried out to detect the phenotypes of colony formation.FACS analysis was used to analyze the cell cycle.The activity of telomerase was examined by telomeric repeat amplification protocol(TRAP) PCR-silver staining.Results 1,25-(OH)2D3 showed significant inhibitory effect on growth of these gastric carcinoma cells at 24,48,72 and 96 h.Treated with 1,25-(OH)2D3 for 48 h,cell cycle showed G0/G1 phase arrest,and the activity of telomerase was inhibited significantly.The colony-forming rate was reduced drastically(P

AIM:To establish HPLC fingerprint for controlling the quality of Rubus chingii Hu. METHODS: Analysis was performed on Alltech C_(18) column(250 mm?4.6 mm,5 ?m)with a mixture of acetonitrile and water as mobile phase in gradient mode,flow rate was 1.0 mL/min,wavelength at 211 nm. RESULTS: There were 15 common peaks in the HPLC fingerprints of Rubus chingii Hu.The RSD of precision and reproducibility lay within 5%. CONCLUSION: The method has good sensitivity and repeatability.This chromatographic fingerprint method can be used to controll the quality of Rubus chingii Hu.

AIM: To study the protective effects of nimodipine liposomes for injection (NDLI) on injuries of total cerebral ischemia/reperfusion(I/R) in rats and anoxia in mice. METHODS: Acute anoxia in mice was produced by hypoxia under normal pressure and decapitation. In these two models the survival time and persistent time of gasping were observed. Ameliorated pulsinelli four-vessel occlusion method was used to make global brain ischemia model. The EEG, the time of righting reflex recovery and Evans blue content in the homogenate of the brain tissues were recorded. RESULTS: NDLI obviously prolonged the survival time and persistent time of gasping in mice subjected to acute anoxia, remarkably shortened the time of EEG recovery and righting reflex recovery, and reduced Evens blue content in the homogenate. CONCLUSION: NDLI has significantly protective effects on injuries of total cerebral I/R and anoxia.

Aim To investigate effects of Icariin in rats with acute myocardial ischemia induced by isoproterenol(ISO).Methods Icariin(12,6,3 mg?kg-1) was administrated through iv pathway for five days.Myocardial ischemia model of rats was induced by subcutaneous injection(sc) of ISO(30 mg?kg-1 for two days,once a day).The change of Electrocardiogram(ECG) was observed.The levels of lactate dehydrogenase (LDH),superoxide dismutase(SOD), malondialdehyde(MDA) and nitric oxide(NO)in serum were measured.Cardiac indexes(HW/BW and LVW/BW)and cardiac infarction area(IS/V%)were examined.Results Compared with the model group,Icariin(12,6,3 mg?kg-1) could effectively reverse the evident change of T wave and J point induced by isoproterenol,notably decrease the levels of LDH and MDA in the serum, distinctly increase the levels of SOD and NO in the serum(P
