Objective To investigate the effect of valsartan combined with ginkgo biloba extract (EGB) in the treatment of early diabetic nephropathy (DN). Methods All of 112 cases of early stage DN patients were randomly divided into treatment group (58 cases) and control group (54 cases). Two groups were given insulin to control blood gluoose and valsartan 80 mg/d. Meanwhile the treatment group was given EGB by intravenous infusion. The changes of urinary protein excretion rate (UAER), urinary β_2-microglobulin (β_2-MG), blood pressure, fasting glucose, serum creatinine (SCr), blood urea nitrogen (BUN), total cholesterol (TC), triglyceride (TG) were compared. Results There was no significant difference in UAER, β_2-MG, systolic blood pressure, diastolic blood pressure, FPG, BUN, SCr, TG and TC before treatment between two groups (P> 0.05). After treatment, they were improved in two groups compared with those before treatment(P < 0.05). Except for systolic blood pressure[(130 ± 13) mm Hg(1 mm Hg = 0.133 kPa) vs(129 ± 11) mm Hg], the improvement in treatment group was superior to that in control group(P<0.05). Conclusions Valsartan combined with EGB in treatment of early DN has significant synergies, and they can play roles with each other to prevent further deterioration of DN. This strategy is worthy to be popularized.

The human plasma lipoprotein-associated phospholipase A2 (Lp-PLA2) is secreted, by the mature macrophages and lymphocytes, which predominantly binds to low-density lipoprotein. Studies in recent years have demonstrated that Lp-PLA2 plays an important role in the process of atherogenesis. Its gene polymorphisms are associated with the occurrence of ischemic stroke, and its specific inhibitor has anti-atherogenic effects. Lp-PLA2 may be a novel independent risk factor and a therapeutic target for ischemic stroke.

Objective To analyze the influence of different types of seizures and nonepileptic events on peripheral white blood cell (WBC)counts. Methods We prospectively collected blood samples from all patients and detered WBC count to evaluate the relation of each type of seizure,duration,frequencies,and ttme lapse between a seizure and collection of blood sample to peripheral WBC count. Results Peripheral WBC count was elevated in about 50% cases after a generalized seizure. The length of a seizures was positively associated, whereas its frequencies and the lapse time was negatively correlated with the increase in WBC counts. Conclusion Peripheral WBC counts increase significantly after a generalized seizure.

Chronic pancreatitis is a chronic inflammatory disease of the pancreas,whichcan lead to irreversible damage to the morphology and function of the pancreas ultimately.So the early diagnosis and treatment for chronic pancreatitis are very important.And the differentiation between mass-forming chronic pancreatitis and pancreatic cancer is also a difficult problem in clinic.MRI as a noninvasive and nonradiative examination with excellent soft tissue resolution,is very valuable for the diagnosis of chronic pancreatitis.And the combination of functional MRI and conventional MRI is very helpful for the differentiation between pancreatic carcinoma and mass-forming chronic pancreatitis,which is of great significance to the clinical management.The application and progresses of function MRI in the diagnosis and identification of chronic pancrea titis were reviewed in this article.

Objective To evaluate the hypoxia selectivity of 99 Tcm O?labeld MAG3?nitroimidazole complexes with different spacers. Methods Four kinds of 99 Tcm O?labeled MAG3?2?nitroimidazole hypoxia imaging agents with different spacers were synthesized and radiolabeled. The stability and lipid solubility of BzMAG3?2NIEA(1), BzMAG3?2NIPA(2), BzMAG3?2NIHA(3) and BzMAG3?2NIUA(4) were measured. The uptake was investigated by biodistribution experiment using S180?bearing mice. Two?sample t test was used for statistical analysis. Results All 4 99 Tcm O?MAG3 complexes were stable and negatively charged, showing an increasing trend in fat solubility with the increase of spacer length. In biodistribution study, tumor uptake of 99TcmO?1 and 99TcmO?2 with medium? and short?carbon chain were (0.67±0.18) and (0?65±0.18) %ID/g 2 h post injection, which were (0.19±0.03) and (0.39±0.05) %ID/g for 99TcmO?3 and 99TcmO?4 with long?carbon chain (t=2.78-5.88, all P<0.05). Conclusion Molecular structure of spacers has a significant effect on the physicochemical properties and tumor targeting of 99 Tcm O?labeled MAG3?2?nitroimidazole hypoxia imaging agents, such that the medium?and short?carbon chain spacers show the best hypoxia?selective property.

This research mainly analysed the section of clinical experience in the reporl of"A panoramic snapshot of medical students'education at the beginning of the 21st century"and gave a brief introduction to the mainstream medical education in No,hem Amercia according to the literature.At last,the enlightment from the report and reformation of our clinical practice were put forward.

Objective To observe the effectiveness of dexamethasone combined with azasetron for the prevention of postoperative nausea and vomiting(PONV) in patients after laparoscopic cholecystectomy(LC).Methods A total of 150 ASA(Ⅰ~Ⅱ) patients undergoing an elective LC were randomly divided into three groups with 50 patients in each group: Group D+A was given intravenous dexamethasone 5mg and azasetron 10mg(2ml) at the end of surgery,Group A received intravenous azasetron 10mg(2ml) at the end of surgery,and Group C received normal saline(NS) 2 ml as the control.Episodes of nausea and vomiting were recorded for 24 h following the surgery.Results The incidence of nausea was 4% in the Group D+A(2/50),which was significantly lower than in the Group A(16%,8/50) and the Group C(34%,17/50)(?~2=4.00 and 14.62;P=0.046 and 0.000).The incidence of vomiting was 2% in the Group D+A(1/50),which was significantly lower than in the Group A (14%,(7/50)) and the Group C(32%,16/50)(?~2=4.89 and 15.95;P=0.027 and 0.000).The incidences of nausea and vomiting were significantly lower in the Group A than in the Group C(?~2=4.32 and 4.57;P=0.038 and 0.033).Conclusions Use of a low dose of dexamethasone in combination with azasetron is more effective than azasetron prophylaxis alone for a successful control of PONV after LC.

Objective:To study the effect of BuShen Prescription on metabolism of collagen Ⅰ in ovariectomized rats,which will provide experimental evidence for treating osteoporosis. Methods:50 Ovariectomized SD rats were randomLy divided into 5 groups,including normal control group,model group,positive control (OVX) group,Zuogui Wan group and Yougui Wan group,each group with 10 rats. After 12 weeks' routine feed,normal control group and model group were intragastric administrated with pure water,positive control group was intragastric administrated with conjugated estrogens water-solution,Zuogui Wan group was intragastric administrated with Zuogui Wan decoction,and Yougui Wan group was intragastric administrated with Yougui Wan decoction,then the PINP,DPYD/Cr,NTX/Cr were detected after ovariectomized rats were intragastric administrated with the schedule for 12 weeks. Results :There was statistically significant difference between Zuogui Wan,Yougui Wan group and model group in decreasing the PINP,DPYD/Cr and NTX/Cr (P

Objective:To observe the bone regeneration capacity of bone defects around BLB implants covered with or without membranes.Methods:Implants were installed into femoral bone of grown-up dogs.Near implants,3 mm horizontal width,5 mm vertical depth and 1,2,3,4 mm horizontal length(along the macroaxis of femoral bone) standard gradient bone defects were made.On one side,the incisions were directly sutured by lamination,and on the other side the incisions were sutured by lamination after using collagen membrane to cover on the defects.Three months after the operation the specimens were observed by stereomicroscopy.Results:In the groups with 1,2 and 3 mm defects,the defect areas had been filled completely with new bone which was mainly compact cortex.In the group with 4 mm defects,the defect areas were filled with new bone which was mainly trabecular bone.Bigger lacunes could be observed in the groups without membranes.Conclusion:If the defect is less than 3 mm,whether bioresorbable collagen membrane is used or not,osseointegration is well in the implant-bone interface.Improving bone regeneration should be done when the bone defect extension is bigger.
