Objective To investigate the effect of growth differentiation factor 11 ( GDF11 ) on aorta in apolipoprotein E-Null( ApoE-/-) mice and its possible mechanisms. Methods Four-week-old healthy male ApoE-/-mice were fed with high-fat diet for 1 week and were then divided into 4 groups:vehicle group(n=10), GDF11 group (n=10),adeno-associated virus-green fluorescent protein group(AAV-GFP group, n=10), and AAV-GDF11 group ( n=10 ) . The mice received intraperitoneal injection with phosphate buffered saline, GDF11 protein, a single injection of purified AAV-GDF11 or AAV-GFP through the tail vein, respectively. After 4 weeks, serum GDF11/8 level and endothelium-dependent vasodilatation were detected. After 12 weeks, serum GDF11/8, interleukin-6 (IL-6), tumor necrosis factor-α( TNF-α), total cholesterol ( TC), triglycerides ( TG), oxidized low density lipoprotein(ox-LDL), and free fatty acids(FFA)levels were measured, the plaque areas in aortic enface and cross sections were measured by oil red O or HE staining, the macrophages/T lymphocytes infiltration in plaques were detected with immunohistochemistry, and the mRNA expressions of IL-6, TNF-α, and IL-10 were determined by real-time PCR. Results Compared with vehicle or AAV-GFP groups, GDF11 and AAV-GDF11 groups presented improved endothelium-dependent vasodilatation, decreased levels of blood inflammatory factors, blood lipid, reduced plaque on face area sections[Vehicle group : GDF11 group:(31. 23 ± 3. 12)% vs (17. 18 ± 2. 17) %;AAV-GFP group : AAV-GDF11 group:(38.01±4.43)% vs(14.54±2.86)%,P<0.05]andcrosssections[Vehiclegroup :GDF11 group:(19. 87 ± 2. 11)% vs (10. 32 ± 1. 47)%;AAV-GFP group : AAV-GDF11 group:(23. 02 ± 2. 76)%vs (9.06±1.63)%, P<0. 05]. There were less macrophages and T lymphocytes infiltration in plaques and lower mRNA expressions of inflammatory factors at aortic wall. Conclusion GDF11 reduces the area of atherosclerotic lesion in ApoE-/-mice, which may be involved in endothelial protection, such as to reduce inflammatory reaction, and to change cellular composition in plaques.

Objective To investigate the effects of growth differentiation factor 11 ( GDF11 ) on β-cell function in db/db mice and its possible mechanism. Methods Twenty eight-week-old male db/db mice were randomizedtoi.p. administration of GDF11(0.3mg·kg-1·day-1)or equivalent PBS(n=10)for 6 weeks.10age-matched male db/m were used as normal control, received equivalent PBS injection for 6 weeks. Blood glucose levels, body weights and food intake were monitored weekly. IPGTT and glucose-stimulated insulin secretion ( GSIS) were analyzed. After 6 weeks of intervention, serum HbA1C , TG, TC, and FFA were measured respectively. The concentrations of hormones in serum and pancreas were evaluated. The mRNA expression of Pdx-1, MafA, Nkx6. 1, and insulin2 were determined by RT-PCR. The expression of phosphorylated Smd2 (P-Smad2), Smad2 in islet were examined by western blot. Results Compared with NC group, GDF11 administration decreased FBG, HbA1C , modified lipid profiles. GDF11 improved glucose tolerance and augmented GSIS. Moreover, GDF11 increased serum insulin and pancreatic insulin content, while decreased serum glucagon concentration. The expression of Pdx-1, MafA, Nkx6. 1, and Insulin2 were significantly increased in GDF11 group. GDF11 elevated the expression of P-Smad2 in islets. Conclusion s GDF11 may preserve β-cell function and facilitate the secretion and production of insulin. Diminishing the metabolic abnormalities, alleviating the secretion of glucagon, as well as maintaining the key transcript factor activation may contribute to the amelioration of β-cell function after GDF11 administration. Smad2 pathway may be related to the protective effects of GDF11.

Objective There have been a few reports on chronically recurrent and generalized superficial mycosis caused by trichophyton rubrum.This article was to investigate the cause, diagnosis and therapy of the mycosis. Methods 5 patients with chron-ically recurrent and generalized superficial mycosis caused by trichophyton rubrum were collected from June 2012 to June 2014 in our hospital.Bacterioscopic examination and cultivation were made on skin lesions of the patients.A typical patient who had 7-year course of desease with toenails seriously infected and widespread skin eruption was selected for histopathology examination on skin lesions, mi-crobiology and molecular biology study on 4 bacterial strains isolated from skin lesions in different parts, and in vitro chemosensitivity assay for drug selection.PCR (rDNA ITS sequence analysis) was performed for diagnosis and early treatment. Results Microscopic examintion on skin lesions demonstrated numerous septate, branched hyphae.Cultivation and molecular biology study identified tricho-phyton rubrum.The strain was identified as trichophyton rubrum by ITS sequence analysis and the isolated strains from different lesions were the same fungal species.Histopathology examination revealed slight hyperplasia of squamous epithelium , epidermal hyperkeratini-zation and the upper dermis presented a sparse perivascular lymphocytic infiltrate.The PAS-stain confirmed the presence of few hyphae in the horny layer.The pathogen of this case was trichophyton rubrum. A combination therapy with systemic itraconazole and topically applied terbinafine hydrochloride cream was successful.A follow-up examina-tion one year later showed no recurrence of symptoms. Conclusion The isolation and identification of pathogen is the key to the diagnosis of chronically recurrent and generalized superficial mycosis, with ad-ditional attention to all or none toenail infection.The therapy should not focus simply on the tinea corporis, while comprehensive treatment combined with chemosensitivity assay is preferred.

OBJECTIVETo observe the sedative and analgesic effects of transcutaneous electrical acupoint stimulation (TEAS) in patients with artificial abortion operation.

METHODSNinety patients, with American Society of Anesthesiologists (ASA) physical status I - II, and scheduled for artificial abortion operation, were randomly divided into three groups, 30 cases in each group. The patients in group A were treated with TEAS on Neiguan (PC 6) and Taichong (LR 3), in group B with paracervical block anesthesia (BA), and in group c with both TEAS and BA. Continuous monitoring of the mean arterial blood pressure (MAP), heart rate (HR), oxygen saturation and bispectral index (BIS) of the patients lasted to 30 min after the operation. The BIS, Visual Analogue Scale (VAS) during the operation and the adverse reactions after the operation were analyzed.

RESULTSAfter 15 minutes TEAS, the BIS in group A and C were decreased significantly, with no significant difference between the two groups (P > 0.05) and being both better than that in group B (both P < 0.05), which had no significant change. There were no significant differences in the VAS among the three groups (all P > 0.05), while the adverse reactions in both group A and C were lower than that in group B (both P < 0.05).

CONCLUSIONTEAS has sedative and analgesic effect during artificial abortion operation and can decrease the adverse reactions.

OBJECTIVETo study the effects of hermap gene on kinases in erythroid signal transduction pathway and investigate the mechanism of hermap on erythroid differentiation.

METHODSThe K562 cells expressing hermap and hermap-siRNA respectively were established for up- and down-regulating the expression of hermap gene. These K562 cells were then induced by Ara-C to erythroid differentiation and analyzed at 0, 24, 48, 72 and 96 h, respectively, for cell morphology and biphenylamine staining positive cells, determination of CD235a, CD36, kinases p-STAT5, p-Akt, p-MAPK and p-c-JUN by FCM; and quantification of hermap gene and γ (Aγ,Gγ) globin gene by FQ-PCR.

RESULTSWith up-regulating hermap gene and inducing by Ara-C, K562 cells were changing to low ratio of nucleus to cytoplasm, cytoplasm colour from basophilic to pinkish or amethyst tinge, increase of number of biphenylamine positive cells and expression of CD235a, CD36, γ (Aγ,Gγ) globin gene, hermap gene and p-STAT5 from 0 to 96 h. At 0, 24, 48, 72 and 96 h of culture, the positive rates of p-STAT5 cells were detected of 0.46%, 4.54%, 20.01%, 23.65% and 33.08%, respectively. This results demonstrated that there was a positive correlation between expression of p-STAT5 and hermap gene expression (P < 0.05).

CONCLUSIONhermap gene can stimulate erythroid differentiation of Ara-C induced K562 cells mainly through JAK/STAT5 signal transduction pathway.

A two-dimensional liquid chromatography method was developed for the analysis of rice leaves proteomics based on the coupling of hydrophilic interaction liquid chromatography-reversed-phase liquid chromatography with online tandem mass spectrometry. The influence of pH value of chromatographic mobile phase on the orthogonality of the hydrophilic interaction-reversed-phase two-dimensional liquid chromatography was evaluated by the changes of standard peptide retention. The results indicated that the better orthogonality (R2=0.34113) was achieved from the system with hydrophilic interaction columns(pH 9.3) in the first and C18columns(pH 3.3) in the second LC dimension. Coupled with multiple fraction concatenation strategy,the orthogonality of two-dimensional liquid chromatography was further evaluated in the analysis of complex rice leaf proteins. The results showed that more than 50% of the total peptides were identified less than two times, and the peptides obtained from first-dimension were well distributed across the elution window,indicating that the method showed significant orthogonality in the identification of complex rice leaf proteins. Based on the proteome discoverer software,207345 peptides belonged to 2930 protein clusters were identified.
