Objective To explore the efficacy and safety of Linagliptin in combination with Metformin in newly diagnosed T2DM patients. Methods A total of 140 newly diagnosed T2DM patients were enrolled in this study. All the patients were admitted in the Endocrinology and Metabolism department of our hospital from January 2013 to October 2013. Random number table method was used in patients’ selection. All the patients were divided into two groups :Linagliptin plus Metformin group (Linagliptin group ,n=70) and Glipizide plus Metformin group (Glipizide group ,n=70) ,and followed up for 12 weeks. Efficacy and safety of treatment were compared between the two groups. Results The difference of FPG ,2 hPG and HbA1 c did not reach the statistical significance between the two groups at baseline treatment (P>0.05). FPG ,2 hPG and HbA1 c were significantly lower after treatment compared with baseline in both groups (P<0.05). FC-P ,2 hC-P ,HOMA-β,HOMA-IR ,IAI and adiponectin level at baseline were similar between the two groups ( P> 0.05 ). All these indicators were improved after treatment in both groups (P< 0.05) ,and were significant better in Linagliptin group than in Glipizide group. Adverse events rate were significantly higher in Glipizide group than in Linagliptin group (18.57%vs 5.71% ,χ2 = 5.423 ,P= 0.020 ). Conclusion The efficacy of Linagliptin in combination with Metformin in newly diagnosed T2DM patients was similar with Glipizide plus Metformin. The β cell function improvement was better and APN level was higher after Linagliptin treatment.

BACKGROUND:Current cardiac bioprostheses and mechanical valves are shown to have some flaws and shortcomings, and tissue-engineered heart valves which can avoid these problems are becoming an ideal choice for valve replacement.
OBJECTIVE:To explore the experimental progress in the construction of tissue-engineered heart valves.
METHODS:Experimental studies related to tissue-engineered heart valves were retrieved in databases. Three main elements for tissue-engineered heart valves are seed cells, scaffold materials, and cellseeding.
RESULTS AND CONCLUSION:Cardiac valve repair and replacement is the primarily surgical treatment for valvular heart disease. At present, seed cells mainly for construction of tissue-engineered heart valves include vascular endothelial cells, endothelial progenitor cells and bone marrow mesenchymal stem cells. The acellular scaffold has good biomechanical properties and histocompatibility. After cellseeding, a continuous celllayer wil form on the scaffold surface, which makes it possible to construct tissue-engineered heart valves. Tissue-engineered heart valve has a good prospect, but it is stil in the early stage of research and there are stil many problems that need to be solved.

Background In previous study,peripheral retinal nerve fiber layer (RNFL) thickness is considered to be the earliest structural changes which can be detected.3D-OCT can measure the thickness of macular ganglion cell complex (mGCC),which makes the detection of primary glaucoma possible in the early stage.Objective This study was to measure the thickness of mGCC and disc-peripheral RNFL in early stage of primary glaucomous eyes by 3D-OCT and assess the anatomic basis of glaucoma-induced optical nerve damage.Methods 3D-OCT images from 10 patients with advanced stage primary glaucoma in one lateral eye and early stage glaucoma in fellow eye from December 2010 to December 2012 were prospectively analyzed in China-Japan Friendship Hospital.The patients were diagnosed based on the recommended standard of National glaucoma group (1987 version) and received routine eye examination.3D-OCT scanning was performed using 3D-macular mode,3D-macular Wide mode and 3D-disc mode with TOPCON 3D-OCT 2000 system,and the images at macular 6 mm×6 mm area were analyzed.The posterior pole area was divided into 5 concentric rings from fovea toward periphery and equally subdivided into 100 small checks,with the area of 0.6 mm×0.6 mm for each.The probable values in each check were calculated as the ratio of each figure and corresponding normal value.The probable values were expressed as red color (P＜ 1％),yellow color (P＜5％) and gray color (P≥ 5％).Then the disc-periphery RNFL thickness and disc cup were evaluated.Results No evident abnormality was found in the thicknesses of photoreceptors layer and bipolar cell layer in both advanced glaucomous eyes and the early stage of glaucomous eyes in the 10 patients.Serious damage of visual field was seen in the advanced glaucomous eyes and presented with red color in the parapapillary RNFL area,mGCC area and macular RNFL area,showing an evidently attenuation of the thicknesses of parapapillary RNFL,mGCC and RNFL.However,the visual field was close normal in the early stage glaucomous eyes,and mGCC and macular RNFL showed yellow color,while green or yellow color was exhibited in the parapapillary RNFL area,indicating mGCC and macular RNFL thickness was reduced,but parapapillar RNFL thickness was near normal.Conclusions The change of mGCC thickness is earlier than that of peripheral RNFL at optic disc in primary glaucomaous eyes,which may imply that the disappear of macular ganglion cell body is earlier than that of the axon.

A 56-year-old female patient of Han nationality presented with generalized erythema and vesicles for 6 days,as well as high fever for 2 days.Twenty days prior to hospitalization,the patient received surgical treatment combined with oral methazolamide and glucocorticoids for glaucoma.The patient had a history of allergy to sulfanilamides.On admission,the patient presented with generalized erythema,vesicles and occasional erosions with bilateral eyelid and oral involvement.Nikolsky's sign was positive.Wheezing sound was heard over the right lung.Genetic testing showed that HLA-B5901 allele was positive.The patient was diagnosed with methazolamide-induced toxic epidermal necrolysis (TEN) complicated by pneumonia,and managed with immunoglobulin (25 g/day,5 days),glucocorticoids (the largest dose equivalent to methylprednisolone 160 mg/day),fresh plasma,antibiotics,as well as other supporting and symptomatic treatments.The condition was controlled after 2 weeks,and the patient was cured and discharged from hospital after 25 days.The fact that the patient carried HLA-B5901 allele suggests that HLA-B5901 is strongly correlated with methazolamide-induced TEN or Stevens-Johnson syndrome in Chinese descendants or Han population,besides in Japanese and Korean descendants.

Objective To evaluate the therapeutic effect of lentinan combined with conventional antituberculous therapy in women with pelvic tuberculosis.Methods A total of 90 women with pelvic tuberculosis were enrolled and recruited into a control group and a treatment group by random number table,45 in each group.The control group was treated with anti-tuberculosis program (2HRZE/4HRE),while the treatment group was treated with lentinan tablets on the basis of the control group.Both groups were treated for 6 months.Serum levels of carbohydrate antigen 125 (CA125) and erythrocyte sedimentation rates (ESRs) were determined before and after treatment,and the therapeutic effect was evaluated.Results After treatment,the serum CA125 level (28.61 ± 9.08 U/ml vs.39.72 ± 12.13 U/ml;t=4.919,P＜0.01) and the ESR (36.13 ± 8.33 mm/h vs.41.35 ± 12.45 mm/h;t=2.338,P＜0.05) in the treatment group were significantly lower than those in the control group.The negative rate of serum CA125 after treatment than before treatment in the treatment group (93.3％ vs.20.0％;X2=46.335,P＜0.01) and the control group (82.2％ vs.8.9％;X2=37.396,P＜0.01);but there was no difference in negative rate of serum CA125 after treatment between two groups (X2=1.6571,P=0.198).The total effective rate in the treatment group was significantly higher than that in the control group (93.3％ vs.77.8％;X2=4.406,P=0.036).Conclusion Lentinan combined with conventional antituberculous therapy is effective in treatment of pelvic tuberculosis in women.

Objective:To explore the effect of endothelin-1 on atrial ifbrosis in patients with atrial ifbrillation (AF).
Methods: A total of 72 patients with thoracotomy were studied, the patients were divided into 2 groups:AF group, n=39 and Sinus rhythm (SR) group, n=33. The mRNA and protein expressions of endothelin-1 (ET-1), platelet derived growth factor-B (PDGF-B) and collagen I (COL1) in right atrial appendage (RAA) tissue were measured by RT-PCR and Western blot analysis;meanwhile, the impact of ET-1 stimulation and non-selective ET-1 receptor antagonist (sulfafurazole SIZ) on PDGF-B mRNA and protein expressions in H9c2 cells were measured.
Results: ①The RAA tissue mRNA and protein expressions in AF group were higher than those in SR group, as for ET-1 (2.830 ± 2.276) vs (1.220 ± 0.887) and (0.835 ± 0.241) vs (0.286 ± 0.083), both P<0.01;for PDGF-B (2.568 ± 2.348) vs (1.567 ± 0.831) and (0.807±0.241) vs (0.381 ± 0.105), both P<0.05;for COL1α1 (3.376 ± 1.598) vs (1.629 ± 0.833) and (0.652 ± 0.210) vs (0.312 ± 0.12), both P<0.05.②The protein expressions of ET-1 and COL1 had positive correlation (r=0.580, P<0.01).③ET-1 promoted PDGF-B secretion in H9c2 cells in a concentration and time-dependent manner;SIZ could reduce such promotion.
Conclusion: ET-1 plays an important role in AF occurrence which might be related to PDGF-B regulation.

Objective To evaluate the feasibility and accuracy of real-time three-dimensional transesophageal echocardiography(TEE) in assessment of left atrial appendage(LAA) function. Methods Forty-two atrial fibrillation patients underwent real-time three-dimensional TEE. LAA ejection fraction based on two-dimensional area measurements(EFA-2D), three-dimensional area measurements(EFA-3D) and three-dimensional volume measurements(EFv-3D) were calculated and related to LAA peak empty velocity (PEV). The variability within observer and interobserver were tested. Results EFA-2D was significantly higher than EFA-3D[(62.84 ± 17.27)% vs (45.39 ± 16.58)%, P = 0.000] and EFv-3D [( 62.84 ±17.27) % vs (48.35 ± 19.37) %, P = 0.001 ], whereas EFA-3D and EFv-3D had no significant difference ( P = 0.158). In a simple linear correlation,the degree of association between EFv-3D and PEV was higher as between EFA-3D and PEV ( r = 0.662 vs 0.604,both P ＜0.05). No significant correlation was observed between EFA-2D and PEV ( r = 0.529, P = 0.130). Variabilities within observer and interobserver were no significant differences by the three methods( P ＞0.05). Conclusions LAA ejection fraction calculation by real-time three-dimensional TEE is feasible and more accurate than by 2D TEE.
