Objective To determine the significance of change of insulin-like growth factor-1(IGF-1) and study the effect of IGF-1 on expression of Bcl-2 and Bax.Methods Male Balb/c mice were randomly divided into control group,coxsackie B3(CVB3) infection group(infection group),CVB3 infection with IGF-1 treated group.Animals were killed at d7,d14.The immunohistochemical studies and medical imagine analysis system were performed to evaluate the expression of Bcl-2 and Bax in myocardial tissue.Serum IGF-1 concentrations were assayed by radioimmunoassay(RIA).Results In infection group,the concentrations of IGF-1 were more decreased than that of control group and the expression of Bcl-2 reduced and Bax increased(P

Objective To investigate change of chemokine mRNA and protein in the patients with diabetes mellitus(DM)complicated infection.Methods Fourty-eight patients with DM complicated infection were studied.Expression of mRNA and protein of monocyte chemoattractant protein-1(MCP-1)and interleukin 8 (IL-8)were measured by FQ-PCR,RT-PCR and ELISA.The relationship between hs-CRP,PMNL,IL-8 and MCP-1 were analyzed.Results Expression of mRNA and protein of MCP-1 and IL-8 were increased in the DM patients complicated infection.MCP-1 mRNA(mesured by FQ-PCR)was positively correlated with the protein(IL-8 r = 0.33;MCP-1 r = 0.88;P

Objective: To study the chemical constituents in the aerial parts of Euphorbia royleana. Methods: The constituents were isolated and purified by chromatographic of silica gel, Sephadex LH-20, RP18, and MCI columns, and their structures were elucidated by spectroscopic analyses. Results: Twelve compounds were isolated from the 70% acetone extracts in the aerial parts of E. royleana and their structures were identified as (6S, 9R)-roseoside (1), 13-carboxyblumenol C 9-O-β-glucoside (2), 3, 3'-dimethylellagic acid-4-O-β-D-glucopyranoside (3), cycloart-23-ene-3β, 25-diol (4), 23(E)-25-methoxycycloart-23-en-3β-ol (5), α-amyrin (6), triptohypol F (7), 9(11), 12-dieneoleana-3β-ol (8), friedelane-3β, 29-diol (9), D:A-friedoolean-29-ol-3-one (10), dischidiol (11), and lupeol (12). Conclusion: Compounds 1, 2, 7-11 are obtained from the plants in Euphorbia L. for the first time and compounds 3-5 and 12 are isolated from this plant for the first time.

Sixteen compounds were isolated from the aerial parts of Euphorbia sikkimensis by means of various chromatographic techniques such as silica gel, Sephades LH-20 and RP-18, and their structures were elucidated as naringenin (1), kaempferol (2), quercetin (3), kaempferol-3-O-alpha-L-arabinopyranoside (4), quercetin-3-O-alpha-L-arabinopyranoside (5), quercetin-3-O-(2"-galloyl)-alpha-L-arabinopyranoside (6), 5alpha, 8alpha-epidioxy-(22E, 24R)-ergosta-6,22-dien-3beta-ol (7), stigmast-5-ene-7-one-3beta-ol (8), 3beta-hydroxy4a, 14alpha-dimethyl-5alpha-ergosta-8, 24(28)-dien-7-one(9), beta-sitosterol (10) , 10-cucurbitadienol( 1) , scopoletin(12) , ethyl gallate(13), p-hydroxybenzaldehyde (14), 3 betahydroxybenzeneethanol( 15) ,and 2,4-dihydroxy-6-methoxy-acetophenone (16) on the basis of spectroscopic data analysis. All the compounds are isolated from this plant for the first time, and compounds 1, 4-8, 15 are obtained from Euphorbia species for the first time.

OBJECTIVETo investigate the clinical application of free superficial iliac circumflex artery skin flaps, as well as the management of donor site defects.

METHODS17 free superficial iliac circumflex artery skin flaps were applied for the traumatic defects or deformities on face, neck, foot, hand, ankle and lower leg, respectively. The donor site defects were closed directly or covered by paraumbilical island flaps.

RESULTSThe 17 flap size ranged from 5 cm x 3 cm to 19 cm x 14 cm. 16 flaps survived completely except 1 flap with partial necrosis, which was closed by free skin graft. The donor site defects were closed directly in 10 cases, and covered by paraumbilical island flaps in 7 flaps without no flap necrosis. The abdomen had a good appearance.

CONCLUSIONSGood appearance can be achieved with free superficial iliac circumflex artery skin flaps for the defects on face, neck, foot, hand, ankle and lower leg. Paraumbilical island flap can be used for the donor site defects.

ObjectiveTo study the situation of grasping knowledge on Cardiopulmonary Resuscitation ( CPR ) among the medical undergraduate interns before going to the clinic.MethodsEighty-five interns enrolled in 2011 were investigated by theory and skill exams to evaluate the cognition level on CPR and the survey results were analyzed by x2.ResultsThe average correct rate of the whole interns' theory and skill was only 44.8％.Theory exams of the clinical group performed better than non-clinical group (x2=8.57,P＜ 0.01 ).There was also no statistically significant difference between the clinical group and the non-clinical group about the average correct rate of the skill (x2=2.72,P＞0.05 )as well as between the female group and the male group (x2=0.03,P＞0.05 ).ConclusionThe medical undergraduate interns'theory and skill of CPR were generally poor,they should be trained before internship.

Objective To investigate the effect of gastrodin on rat vascular smooth muscle cell (VSMC) migration induced by platelet-derived growth factor-BB (PDGF-BB) and its possible mechanisms.Methods Enzyme digestion method wasused to obtain rataorticVSMCs and be purified bypassage.Immunofluorescence staining was used to identify VSMC marker proteins.A PDGF-BB induced cell migration model was established.Transwell chamber assay was used to evaluate the effect of gastrodin on PDGF-BB induced VSMC migration.Western blots were performed to detect the phosphohorylation levels of c-jun N-terminal kinase (JNK).Results The purity of primary cultured VSMC was more than 99％.The VSMC migrated number in the PDGF-BB group was 85.2 ± 3.486 per field.It was significantly more than 42.5 ± 1.927 per field in the control group (t =9.981,P＜0.001),and gastrodin was enable to make PDGF-BB induced the number of VSMC migration significantly reduce to 71.3 ± 1.783 per filed (t=3.550,P =0.002).Western blots analysis showed that gastrodin inhibited PDGF-BB induced JNK phosphorylation (0.190 ± 0.015 vs.0.190 ± 0.015; t =14.548,P =0.000).Conclusions Gastrodin inhibits PDGF-BB induced VSMC migration,its mechanisms may be associated with the inhibition of the JNK signaling pathway activation.
