Objective To study the effect of acarbose on vascular endothelial function in patients with impaired glucose tolerance (IGT).Methods Fifty-six cases with IGT were chosen by OGTT,and they were divided into control group(27 cases) and therapy group(29 cases) by systematic sampling.The patients in control group were received placebo,the patients in therapy group were given acarbose 25-50 rug,3 times daily for 12 weeks.The body mass index (BMI),blood fat,fasting blood glucose (FPG),fasting insulin (FINS),glycosylated hemoglobin (HbA1c),high sensitivity C-reactive protein (hs-CRP),von Willebrand factor (vWF),2 h post-meal glucose (2hPG),2 h post-meal insulin (2hINS) and brachial artery endothelium-dependent dilation (EDD) was detected before and after treatment in two groups.Results Compared with that before treatment,BMI,2hPG,2hINS,HbA1c,hs-CRP and vWF were decreased and brachial artery EDD was improved after treatment in therapy group[ (24.69 ± 2.62) kg/m2 vs.(22.02 ± 2.59)kg/m2,(9.26 ± 1.02) mmol/L vs.(7.43 ± 0.95) mmol/L,(42.17 ± 9.98) U/L vs.(34.76 ± 9.86) U/L,(6.03 ±0.67)％ vs.(5.37 ±0.56)％,(5.45 ± 1.93) mg/L vs.(4.52 ± 1.55) mg/L,(187.22 ±26.57)％ vs.(165.13 ± 23.86)％,(6.08 ± 1.22)％ vs.(7.94 ± 1.25)％ ] (P ＜ 0.05 or ＜ 0.01).There was no significant difference before and after treatment in control group (P ＞ 0.05).Conclusion Acarbose can improve brachial artery EDD in patients with IGT by increasing insulin sensitivity and decreasing postprandial hyperglycemia and inflammatory factor,which delays the progression of diabetic mellitus and atherosclerosis.

[Objective] To discuss the surgical treatment strategy of spinal hemangioma.[Methods]Data on 33 patients with spinal hemangioma treated from October 1997 to October 2008 were reviewed.There were 19 females and 14 males.The average age was 54 years old.Chief complaints were pain(n=13),myelopathy(n=12),radiculopathy plus local pain(n=8).Nine patients without spinal cord and radial nerve compression underwent percutaneous vertebroplasty(PVP),and 24 patients with spinal cord and radial nerve compression,paravertebral soft tissue mass or spinal unstability were treated by operation.Anterior,anteroposterior and posterior approaches were used in 9,12,and 3 patients respectively.Transarterial embolization was done in 3 patients.[Results]No perioperative complication was observed in 9 patients after PVP,with a mean follow-up of 41 months.Pain was relieved.There was no perioperative death among the 24 patients who received operation.The blood loss during operation was 2739 ml and 1619 ml for anterior and posterior approaches,respectively(P=0.12).One case of paravertebral hematoma,one case of spinal canal hematoma,and one case of wound infection were observed in this group.Pain was relieved in 89%(17/19)of the patients.According to the Frankel Scale,the neurologic situation was improved in all the 12 patients with myelopathy.By a mean follow-up of 48 months,no internal fixation failure was seen.Tumor recurrence or growth was found in 4 patients,two had no symptoms and one underwent radiotherapy for pain.Repeated operation was performed in one patient with myelopathy.[Conclusion]Most patients with symptomatic spinal hemangioma could be treated successfully by surgery.Individual surgical plan should be made according to the reason causing symptoms and the general condition of the patient.

AIM: To observe the effects of Shexiang Baoxin Pill supplement on the patients with unstable angina pectoris(UAP),and study its mechanism. METHODS: Subjects recruited from 56 patients with UAP were randomly divided into control group and Shexiang Baoxin Pill group.The former received such therapy as expanding coronary artery,anticoagulation,adjusting lipemia 2 pills of Shexiang Baoxin Pill were given to each cases of the latter for 3 times every day orally besides routine therapy,3 months later,to review their plasm von Willebrand Factor(vWF) and fibrnogen 1(Fbg) and brachial artery endotheliumdependent dilation,its results were compared with the control group. RESULTS: Plasm vWF and Fbg of the control-group and Shexiang Baoxin Pill group decreased significantly((192.56%)?(27.37%) vs(179.23%)?(24.98%) P

Objective To evaluate the role and safety of continuous vano-venous hemofiltration(CVVH) in treating critical patients. Methods We summarized 109 cases of critical patients treated by CVVH in our ICU from 2002 to 2006. Results The therapy time ranged from 18 to 72 hours. Of all patients, there were 13 cases of hypotension, 5 cases of filter occlusion,2 cases of bleeding and 3 cases of local or blood infection. Conclusion CVVH can be appli-Gated in critical patients with good safety and efficiency. High-quality management plays an important role in the carry--out of CVVH.

Objective To evaluate the clinical applications of noninvasive mechanical ventilation in the treatment of acute cardiogenic pulmonary edema. Methods From Jan.2002 to Apr.2004 60 patients in Dalan Municipal Central Hospital were randomly assigned to receire conventional oxygen therapy or NMV supplied by a standard ventilator through a face mask,with adjustment of pressure support at 8-15 cm H_2O in addition to a positive end-expiratory pressure of 5-8 cmH_2O.Blood gas and vital signs were obtained at 1 h,2 h,3 h,4 h,and 12h.Results Endotracheal intubation was required in 5(16.7%)of 30 patients assigned to receire NMV and in 12(41.4%)of 29 assigned to receive conventional oxygen therapy(P=0037). Resolution time was significantly shorter in the NMV groupmedian 40(5~77)vs145(49~263)min,P

AIM:To investigate the protective effects of Danshen Tablet on the brachial artery flow-mediated dilatation(FMD)in the subjects accompanied with risk factors of coronary heart disease(CHD). METHODS: Fifty-five subjects were randomly assigned to two groups,therapy group(32 cases)were administrated Danshen Tablet(three tablets once,three times a day),the control group(23 cases) were received placebo and then observed their brachial artery FMD before and after three months' therapy.Meanwhile 19 healthy cases were compared with the subjects. RESULTS: The brachial artery endothelium-dependent dilation(EDD) of the subjects accompanied with risk factors of CHD was significantly lower than that in the normal group[(5.98?1.13)%,(5.95?1.14)%vs((8.11?1.25)%,) P

Objective To investigate the pharmacological action of Shuanglong Prescription on cardiac function in dogs and to study its mechanism. Methods The changes of the parameters such as coronary blood flow, myocardial oxygen consumption and heart rates were observed in normal anesthetic dogs. Results Compared to those in the normal group, the coronary blood flow increased and the heart rates decreased in Shuanglong Prescription group. Conclusion Shuanglong Prescription can regulate and improve the cardiac function of dogs.

Objective: To evaluate the long-term effectiveness of sulindac on the pathology of colorectal adenomas of familial adenomatous polyposis (FAP) patients. Methods: FAP patients were treated with sulindac 400 mg per day. The change of colorectal polyps was assessed every 3 months in the first year. After the significant regression of colorectal polyps was achieved, sulindac was used to maintain the effects. The patients received colonoscopy examination regularly. Biopsies of remnant polyps and other lesions were obtained. The type and dysplasia grade of biopsies were evaluated and compared with baseline. Results: Before the study, 90.8% of adenoma biopsies were tubular, while 9.2% was tubulovillous adenoma. The dysplasia of grades Ⅰ, Ⅱ and Ⅲ were 42.1%, 45.6% and 12.3%, respectively. After sulindac treatment, 99.8% of adenoma biopsies were tubular, while 0.2% tubulovillous adenoma. There was significant difference compared with baseline (P
