OBJECTIVE: Newer medicine therapies have been proved efficacy in patients with intermittent claudication. With rapid advances of intervention devices and techniques for peripheral vessels in recent years, which has improved the therapy of peripheral artery disease (PAD). To review the clinical developments in treatment of PAD so as to provide references for optimal integrated therapy of medicine with proper interventional treatment, which enable PAD patients to achieve the greatest long-term prognosis. DATA SOURCES: A computer-based search for literatures related to PAD from 1991 to April 2006 was conducted in Medline databasewith the of "peripheral arterial disease, catheterization, peripheral, genetics", and the language was limited to English. Meanwhile, Chinese relevant literatures between 1994 and April 2006 were searched in Journal Full-text Database and Wanfang Database by computer with the keywords of "peripheral arterial disease, intermittent claudication, management". STUDY SELECTION: Primary selection was performed by following inclusive criteria: PDA and drug treatment, stent, angioplasty, genetic therapy, surgery, and articles related to PDA were selected. Scientific criteria of treatment for PDA were looked for in basic researches, clinical studies and those published in formal organizations. Exclusive criteria: Repetitive studies, reviews and Meta analytical literatures were excluded. DATA EXTRACTION: A total of 60 literatures about the treatment for PDA were collected, 30 enrolled articles in which were reviewed. Thirty repetitive studies, reviews and Meta analytical literatures were excluded. DATA SYNTHESIS: ①The prevalence of PAD depends on the diagnosis. Given the inaccuracy of physical examination, use of pulse examination as the sole criterion would grossly overestimate the prevalence. In contrast, a historical query for intermittent claudication would underestimate the prevalence of PAD. The ankle-brachial index (ABI) has been validated by angiography with the sensitivity of 95% and the specificity of 100%.②The risk factors of PAD were similar to those in patients with cardiovascular disease and cerebrovascular disease. The goals of therapy for patients with PAD are to prevent systemic atherosclerotic disease progression and clinical cardiovascular events as well as prevent limb loss and improve the functional status of patients with intermittent caludication.③Medical therapy of PAD should include manipulations of risk factors for atherosclerotic heart disease, including smoke-stopping, body mass reducing, blood glucose controlling, blood pressure controlling and hypercholestermia reducing etc. Instructive exercise therapy is the most effective way in non-interventional therapy, while medicine therapy mainly included antiplatelet therapy, angiotenic therapy and anticoagulation therapy. If the patients has obvious clinical ischemia symptoms and cannot be relieved by medical treatment, then interventional therapy or surgery is necessary. CONCLUSION: Patients with PAD can achieve the best long-term prognosis by an instructive exercise treatment integrated with optimal medicine therapy and proper interventional therapy.

Objective To investigate the psychological characteristics and personality of perinatal women, and to provide evidence for effective psychological intervention. Methods Five hundred and seventy pregnant women were randomly selected from the out-patient department from October, 2002 to March, 2003. Eysenck Personality Questionnaire(EPQ) , Self-rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS) were applied for their personality, psychological characteristics and the influencing factors. Psychological surveys were performed in 216 cases in labor, and 300 cases were followed up during 1-5 days and 42-60 days postpartum. Results During pregnant period, the incidence of anxiety and depression was 10. 5% and 10. 2%, respectively, while 4. 0% and 5. 3% during early stage of puerperium. The rate of depression was 40. 7% and 10. 0% during late stage of puerperium and after puerperium. Pregnant women with personality of stability were less likely to have psychological disorder. Conclusions The rate of psychological disorder varies in different per sonallity. Proper intervention among high risk pregnant women is important in perinatal psychological

Objective To explore the diagnostic value of NAP activity detection in SLE.Methods Technique of AS-BI was used to NAP staining of peripheral blood smear in patients with newly-diagnosed SLE(30 cases)and normal healthy women(30 cases),to observe positive rate and positive score of NAP.Results The positive rate was(22.1±8.8)% in group SLE,(56.8±9.4)% in group normal;The positive score was(22.2±8.9)in group SLE,(58.2±9.8)in group normal.The positive rate and positive score were much lower in patients with SLE comparing with those in group normal.Differences were statistically significant(P＜0.01).Conclusions The detection of NAP is useful in the patients with newly-diagnosed SLE,but we must go on researching the pathogenesis of NAP activity decreased in SLE.

Objective To explore the biological effects of the luteinizing hormone receptor (LHR) and vascular endothelial growth factor (VEGF) on the ovary of mice during peri-implantation. Methods The immunohistochemistry SABC method and image analysis were used to study the distribution and changes of the LHR and VEGF in Kunming mouse( n =28) ovary during estrous,pregnancy of day 1, day 4 and day 6 stage. Results The expression of LHR-immunoreactive substance and that of VEGF-immunoreactive substance had the same distribution and changes. Compared with other groups,the level of LHR-immunoreactive substance and that of VEGF-immunoreactive substance increased highly on the stroma cells around largergrowing follicles in estrous group ( P <0.05). Along with the pregnancy, the positive immunostaining for LHR and VEGF increased gradually on the granulosa lutein cells, and reached the highest level on day 6 of pregnancy. Positive immunostaining for LHR or VEGF on some endothelia and blood cells were observed in day 1 of pregnancy or estrous group respectively. Form day 1 of pregnancy, the theca cells had positive immunostaining for LHR. Conclusion The expression of LHR and VEGF is closely related with the process of follicle growing, ovulation and corpus luteum formation.

Objective To investigate the mechanism of a dipeptidyl-peptidase-4 (DPP-4) inhibitor, saxagliptin, pro?moting the regeneration of islet beta cells in diabetic rats. Methods The male SD rats were randomly divided into three groups including control group (NC, n=10), diabetes group (DM, n=10) and diabetes treated with saxagliptin group (DM-S, n=10). DM-S group was treated with saxagliptin 1 mg/(kg·d) for twelve weeks. The pancreaticβcell function was analysed by hyperglycemic clamps. Immunohistochemistry with anti-PCNA was performed to observe the proliferation rate of pancreaticβcells. Immunofluorescence double staining with anti-insulin, anti-glucagon, anti-DPP-4 and anti-SDF-1 were performed to observe the expression of insulin, glucagon, DPP-4 and SDF-1 in pancreatic tissue. Western blot assay was performed to test the expression of Akt, p-Akt,β-catenin and free-β-catenin protein, and RT-PCR was performed to test the expressionlevels of c-myc and cyclinD1 mRNA in pancreatic tissue. Results Compared with NC group, there were significantly in?creased blood glucose, decreased islet function andβcell mass in DM group. Compared with DM rats, saxagliptin treatment significantly inhibited the expression of DPP-4, decreased the degradation of SDF-1, stimulated the proliferation ofβcells, and ultimately improved the islet function and histopathological changes of pancreas. Conclusion DPP-4 inhibitor saxa?gliptin can significantly improve islet function, which involved in the inhibition of the expression of DPP-4, the decreased degradation of SDF-1 and the stimulation of the proliferation ofβcells.
