[Summary] Glucagon-like peptide-1 ( GLP-1 ) agents play important roles in glycemic control in type 2 diabetes. Moreover, these agents also show various protective effects on cardiovascular system. GLP-1 agents improve vascular endothelial function, ameliorate the risk factors of cardiovascular disease including obesity, hyperglycemia, dyslipidemia and hypertension, delay the occurrence and progression of atherosclerosis, and protect against cardiac ischemia-reperfusion injury and heart failure. Therefore, GLP-1 agents may have beneficial effects on cardiovascular diseases at different stages and in multiple aspects.

Neurofibromatosis type 1 is a term of Von Recklinghausenan.It is an autosomal dominant inherited disease which derived by neural crest cell.Prevalence of this disease is 1/3000 1/3500 and is a disease with the highest mutation rate.The pathogenesis of neurofibromatosis type 1 is associated with the deficiency of NF1 gene.Recently,the genetics and genomics research of neurofibromatosis make a great progress.With the development of gene linkage and position cloning technology,the gene sequence of neurofibromatosis type 1 has been found.Recent research of genetics and genomics of NF1 and the structure and function,abnormal expression,the relation of genotype and phenotype,the mutation sensitivity domain of NF1 gene were reviewed.

To study the chemical constituents of Cirsium setosum (Willd.) MB., 70% ethanol extract of the aerial parts was subjected to column chromatography. One new phenylpropanoid glycoside, sinapyl alcohol 9-O-(E)-p-coumaroyl-4-O-beta-D-glucopyanoside (1) was isolated, along with three known compounds: lycoperodine-1 (2), apigenin-7-O-(6"-(E)-p-coumaroyl)-beta-D-galactopyranoside (3) and quercetin (4). The structures were elucidated on the basis of spectral and chemical evidence. Compound 2 was obtained from Cirsium genus for the first time, compounds 3 and 4 were obtained from this plant for the first time.

Objective To investigate the relationship between exposure intensity and illumination time of blue light and replicative senescence of rat retinal pigment epithelial (RPE) ceils.Methods Thirty-six 12-14 weeks Wistar rats were kept in the cage with a blue-light bulb [(450±10) nm],and were randomly divided into four groups (no light,nature light,500 lx light and 1000 lx light illumination),each has nine rats.The rats in each group were further divided into three subgroups according to illumination time (one month,two months or three months).Eyeballs were collected after intraperitoneal injection of 10% chloral hydrate.The right eye of each rat was embedded in paraffin and sectioned for hematoxylin-eosin (HE)staining,while frozen sections of the left eye were stained for the senescence-associated β-galactosidase (SA-β-Gal).The data were analyzed by SPSS11.5 statistical software.Results The amounts of SA-β-Gal positive RPE cells were significantly different between all groups under the same illumination time 17 (P=0.000),and between all subgroups of different illumination time with same exposure intensity (P＜0.01)except for the control group (no light).Conclusion Blue-light can induce replicative senescence in rat RPE cells in an intensity and time-dependent manner.

Objective Adverse reactions to Gd-DTPA contrast media should be noticed enough.Methods Three cases of adverse reactions to Gd-DTPA contrast media were studied, and literatures were reviewed.Results The rate of adverse reactions to Gd-DTPA contrast media in our hospital was 0.206%.Conclusion Although the rate of adverse reactions to Gd-DTPA contrast media is very low, this problem must be noticed enough with the medical quality’s developement.

Objective To introduce the technique and treatment outcome of the fingertip soft tissue defect with improved transverse palmar island flap.Methods From January 2011 to February 2013,15 cases(17 fingers) fingertip defect were repaired by improved transverse palmar island flap,the vascular pedicled of flap was a side of the neurovascular bundle,the flap revolved 90° to coversoft tissue defect.Defect area:1.2 cm × 0.8 cm to 1.7 cm × 1.6 cm.The time between the injury and admission was 40 minutes to 27 hours.Five cases were repaired defection with flap immediately,10 cases were repaired defection in stage Ⅱ.Results The wounds of injury in 15 cases get primary healing,and all the flaps were successfully survived.The 13 cases were followed up for 6 months to 14 months.The blood circulation of flap was fine,and the fingertip shape as well.The two point discrimination of the skin pulp was 6 mm to 11 mm.Conclusion The improved transverse palmar island flap for repairing transverse finger pulp defect and a small area of skin defect in patients.The procedure has a simple surgery,donor area don't skin graft,postoperative appearance and hand finger satisfactory functional recovery,etc.

Objective: To investigate the effect of scalp point-through-point acupuncture on 200 kDa neurofilament protein (NF-200) in rats with acute cerebral infarction and explore its mechanism on nerve plasticity in cerebral infarction rats. Methods: Healthy male Wistar rats were randomly allocated to sham operation (Group A), model (Group B) and acupuncture (Group C) groups. A rat middle cerebral artery occlusion (MCAO) model of cerebral ischemia was made. NF-200 mRNA was measured by reverse transcriptase polymerase chain reaction (RT-PCR) in each group on the 7th, 14th and 28th days. Results: The cerebral expression of NF-200 in group C was significantly different from those in groups A and B (P＜0.05); there was a significant difference between groups C and B or A at different time windows (P＜0.01),indicating that scalp point-through-point acupuncture could improve the cerebral expression of NF-200. Conclusion: Scalp point-through-point acupuncture can improve neural function,promote the recovery of limb function and increase the expression of NF-200 after cerebral ischemia, exerting a regulative effect on neuronal plasticity in the brain.

This paper presented the practice of performance evaluation at public hospitals in Wuhu.The performance evaluation system at public hospitals should emphasize public benefits,present a true picture of work and management performance,and help build the incentive and constraint mechanism.In addition,it should encourage public hospitals to strengthen management,improve quality of care and control health care costs.The system is designed for providing a safe,effective,convenient and inexpensive medical and health services for the people.
