Objective To study the changes in the endothelial reserve capacity to release tissue plasminogen activator (tPA) and nitric oxide (NO) and its relation to vasodilation and to diabetic angiopathy. Methods The capacity of vascular endothelium to release tPA and NO was examined by venous occlusion of the upper arm. Brachial artery diameter was measured at baseline, during postocclusion reactive hyperemia (flow-mediated endothelium-dependent), and after sublingual nitroglycerol administration (endothelium-independent), using a high resolution ultrasound technique in 15 control subjects and 23 patients with type 2 diabetes mellitus. Vasodilation was expressed as the percentage change relative to the baseline diameter, while endothelial tPA and NO release was expressed as the percentage change relative to the baseline tPA and NO levels. Thickness of the intima of carotid artery was measured using ultrasound imaging. Results There was no significant difference in endothelium-independent vasodilation between control subjects and diabetics. However, significant reductions in endothelium-dependent vasodilation (P

With the development of mass spectrometer,protein and peptide separation technology,and data analysis tools,the study on protein expression profiling of various tissues,organs or cells has been developed rapidly.The most basic purpose of proteomics is qualitative and quantitative identification of the whole protein in a cell or tissue.Therefore,how to make full use of mass spectrometry data has an important significance in proteome.Recently years,proteomics has begun to be applied in allograft rejection and discovery of rejection related biomarkers in organ transplantation.Through the extensive application of the technology in organ transplantation,graft rejection can be earlier detection and treatment.Therefore,the proteomics research have potential application prospects in the diagnosis of the organ transplant rejection.

Objective This research is proposed to improve the recognition of the clinical features, therapy and prognosis of palindromic rheumatism.Methods We analyzed the clinical data of 63 palindromic rheumatism patients.Their response to therapy was observed,and they were followed up for 1.5 to 3 years. Results The average onset age of the patients was(40?11)years and the average disease duration was(8?7) years.They were characterized by recurrent attacks of sudden-onset acute arthritis and(or)periarticular tis- sue inflammation,in which most joints were involved.In 46 percent of the patients,the attacks were incited by some events.In 67 percent of them,the attacks recurred more and more frequently.Nonsteroidal anti-in- flammatory drugs and disease modifying anti-rheumatic drugs(DMARDs)was effeeive in variant extents,to palindromic rheumatism patients.Five percent of patients achieved complete remission.Nine percent of them had relapses for a long time.And 5% of them evolved to RA.Conclusion Palindromic rheumatism is a syn- drome characterized by recurrent attacks of sudden-onset acute arthritis and(or)periarticular tissue inflam- mation.The therapy of DMARDs,especially penicillamine and chloroquine diphosphate,is effective on the syndrome.The outcomes of palindromic rheumatism is diverse.

[Summary] The basic data and serum targets of 3 349 residents were collected by multi stage stratified cluster random sampling and analyzed by correlation and regression analysis to access its association with cardiovascular risk factors. The result showed that morbidity of hyperuricemia was 18. 85% . The risk of hyperuricemia was raised in people with high triglycerides, high low-density lipoprotein-cholesterol ( LDL-C), low high-density lipoprotein-cholesterol(HDL-C), and low estimated glomerular filtration rate(eGFR). The people with hyperuricemia are usually accompanied with many cardiovascular risk factors.

Objective To establish a Loop-mediated Isothermal Amplification (LAMP) for Pseudomonas aeruginosa rapid detection. Method 152 P. aeruginosa strains isolated from nasal swabs and 30 reference strains were applied. P. aeruginosa ATCC15442 was used to develop LAMP amplification and evaluate sensitivity and specificity. Results Sensitivity of LAMP was 103 times higher than PCR, with DNA amount as 132 fg. When LAMP was applied to 30 reference strains and 152 P. aeruginosa strains , the specification was 100% while iden-tification rate reached 94.7%. Conclusion The establishment LAMP showed a promising prospect in P. aerugi-nosa rapid detection.

Mixed saponin molecules in the extraction of Panax notoginseng(PNE) can be effectively desorpted into the molecular ionization for measurement and analysis by mass analyzer from matrix assisted laser desorption ionization-time of flight-mass spectrometry(MALDI-TOF MS). The saponin samples with chromatography purity were directly analyzed by MALDI-TOF MS, which indicated that the sensitivity of the method was higher than that of RP-HPLC. A technology of MALDI-TOF MS was directly employed to analyze the saponin kinds and their relative contents in Panax notoginseng(PN) while the saponins were perfectly extracted from the Chinese traditional medicine of PN. It was indicated that there were at least 20 saponins consisting of different molecular structure and that the content of both ginsenoside Rg1 and notoginsenoside R1 in PNE was relative high. R1 saponin was extracted and identified to follow its metabolism pathway by both thin layer chromatography and MALDI-TOF MS, respectively. The saponin fingerprinting maps in PNE can be established to evaluate the quality of PE and to study both metabolism pathway and mechanism of extra minim saponins in vivo.

Objective:To discuss the effect of radiation of Nd:YAG laser in apical retrograde filling. Methods: 50 similar roots were randomly divided into 5 groups.The anatomical crowns were removed at the cementoenamel junction and the remaining roots were treated endodontically with conventional methods before the apical 2 mm were cut and a dish-like hole made in the cutting surface by high speed round bur. Except the first group,each hole were radiated by the Nd:YAG laser for different time or with different patterns and after that,the glass ionomer cement were retrofilled into the hole. A microleakage measurements were carried out and the result were measured and recorded. The hole surface was also observed under electron microscopy. Results:The leakage of the groups with Nd:YAG radiation were decreased significantly(P

OBJECTIVE:To investigate the way to provide suitable pharmacecaical care for antineophastic drug-induced ADR by clinical pharmacists. METHODS:For one case of 5-FU chemotherapy-induced neutropenia associated with fever and diarrhea, clinical pharmacists provided advices on antibacterial treatment,including imipenem/cilastatin 0.5 g,q6 h,ivgtt;norvancomycin 0.4 g,q6 h,po;levofloxacin 0.4 g,qd,ivgtt;loperamide with initial dose of 4 mg for anti-diarrheal medication,maintaining at 2 mg,q4 h. RESULTS:After 22 days of appropriate antibacterial and anti-diarrheal treatment,the patient's body temperature and he-mogram returned to normal,diarrhea stopped and β-HCG decreased to 61.58 U/L;then the patient was discharged from hospital. CONCLUSIONS:It is beneficial to optimize chemotherapy plan and ADR disposal,and ensure the safety of the treatment that clini-cal pharmacists assist physicans to optimize therapy plan and provide pharmaceutical care.

Objective To investigate whether nimodipine could reduce complications after microvascular decompression in patients with hemifacial spasm. Methods 220 patients with hemifacial spasm , admitted into our hospital from May 2011 to Oct. 2013 , were all treated by microvascular decompression. They were divided randomly into two groups. Patients in the treatment group were treated with nimotop 50 mg/d after the operation for the first 3 days, then was orally taken 30 mg/d for a week. Patients in the control group were treated with the same after the operation without nimodipine. The postoperative complications including hearing deficit and peripheral facial paralysis were closely observed within three months after operation. Results The total effective rate was 100% in both groups. The incidence rate of peripheral facial paralysis and hearing deficit in treatment group was significant lower than that of the control group (P < 0.05). Conclusion Nimodipine has significant effect on reducing the incidence rate of peripheral facial paralysis and hearing deficit after microvascular decompression in patients with hemifacial spasm.

Objective To explore the clinical effect of posterior indirect reduction and internal fixation and laminectomy in the treatment of thoracolumbar vertebrae burst fracture complicated with spinal cord injury.Methods Eighty patients with thoracolumbar vertebrae burst fracture and spinal cord injury treated in our hospital from March 2014 to March 2015 were selected as the objects,and they were divided into reset group and laminectomy group with forty cases in each group according to surgical method.All the patients were followed up for 1 year,the lumbar function of two groups at 1 week and 1 year after operation were observed respectively,and the pain degree was observed in 1month,3 months and 6 months after operation.The amount of bleeding,operation time,hospitalization time and fracture healing time were observed.Neurological function was assessed by classification criteria of the American Spinal Cord Injury Association(ASIA),and incidence of complications was figured in the two groups.Results The anterior heights of the injured vertebra were higher than those before the operation,and the Cobb's angles were lower than those before the operation,the differences were significant(P ＜ 0.05);while there was no significant differences in the anterior heights of the injured vertebra between the two groups at 1 week and 1 year after operation(P ＞ 0.05).VAS scores of the two groups after 1 month,3 months and 6 months decreased significantly when compared with the preoperative scores(P ＜ 0.05),and VAS scores of each time in the reset group were significantly lower than those in the laminectomy group(P ＜ 0.05).The amount of bleeding,operation time,hospitalization time and fracture healing time in the reset group were less than those in the laminectomy group (P ＜ 0.05).The neurological function recovery of the two groups were significantly improved when compared with that before the operation(P ＜0.05).There was no significant difference in recovery of neurological function between the two groups(P ＞ 0.05).The complication rate was 7.50％ in the reset group,lower than 12.50％ of the laminectomy group,the difference was significant (P ＜ 0.05).Conclusion Posterior indirect reduction and internal fixation of lamina both have a certain effect in the treatment of thoracolumbar vertebrae burst fracture complicated with spinal cord injury.But posterior indirect reduction has less complications and less amount of bleeding,which is beneficial to postoperative recovery.
