Donor shortage in corneal transplantation is an emerging issue.Recent studies showed that compared with other organ transplantation,the rejection of corneal transplantation is weak due to the immune privilege,and the anatomical and biomechanical properties of human corneas are similar to pig corneas,so genetically engineered pigs have great potentials as a new source for clinical transplantation.This review discussed current knowledge of the pathogenesis of the rejection mechanism,recent advances in gene engineering pig,and feasibility of porcine xenocorneal graft.

Asymmetric dimethylarginine(ADMA)is a nitric oxide synthase(NOS)inhibitor.ADMA is formed by methylation of L-arginine residues.It innbits the formation of vasoactive substances(nitric oxide),resulting in endothelial dysfunction and vaseular diseases.A number of studies have suggested that ADMA may be a risk factor for stroke.The expression of ADMA increases significantly in patients with hyperhomocysteinemia,carotid stenosis and cardiovascular disease.

ObjectiveTo study the effect of nutritional intervention combined with aerobic exercises on serum adiponectin and insulin resistance in nonalcoholic fatty liver (NAFL) patients.Methods32 patients confirmed as NAFL between April 2008 and August 2009 were enrolled into NAFL group and 31 health people into control group.NAFL group received nutritional intervention and followed aerobic exercise program.The changes of body mass index (BMI),serum adiponectin,fasting blood glucose (FBG),fasting insulin (FINS) and serum lipids were recorded before and after interventions.Insulin resistance index (HOMA-IR) was calculated.Inter-group difference,changes after intervention,and correlation between serum adiponectin and the other indexes were analyzed.ResultsCompared with the control group,BMI [ (29.84 ±3.16) kg/m2 vs.(22.22 ± 1.81 ) kg/m2,P =0.000],total cholesterol (TC) [ (5.09 ±0.86) mmol/L vs.(4.38 ±0.85) mmol/L,P =0.002],triglyceride (TG) [ (1.99±0.86) mmol/Lvs.(1.10±0.38) mmol/L,P=0.000],FBG[ (6.02±0.63) mmol/Lvs.(5.02±0.71) mmol/L,P=0.000],FINS[ (13.73±3.24) mU/Lvs.(9.55±1.99) mU/L,P=0.000],HOMA-IR [ (3.74±1.21) mmol/L vs.(2.08 ±0.27) mmol/L,P=0.000] in the NAFL group were significantly higher,while serum adiponectin in the NAFL group was significantly lower [ (4.89 ± 1.81 ) ug/L vs.( 12.97 ± 3.15 ) ug/L,P =0.000 ].After nutritional intervention and aerobic exercises,BMI [ ( 26.65 ± 2.39 ) kg,/m2 vs.(29.84 ±3.16) kg/m2,P =0.000] 、FBG [ (5.61 ±0.47) mmol/L vs.(6.02 ±0.63) mmol/L,P =0.004 ],and FINS [ ( 11.12 ± 2.01 ) mU/L vs.( 13.73 ± 3.24) mU/L,P =0.000 ] in the NAFL group were decreased significantly,while serum adiponectin [ (6.54 ±2.12) ug/L vs.(4.89 ± 1.81 ) ug/L,P =0.001 ] was significantly higher than the level before intervention.Serum adiponectin was negatively correlated with BMI,FBG,FINS,HOMA-IR,and TG (P =0.004,0.000,0.000,0.000,and 0.010),and positively correlated with high density lipoprotein cholesterol (P =0.026),but not correlated with TC (P =0.101 ).ConclusionThe combination of nutritional intervention and aerobic exercises can improve the level of serum adiponectin,adjust the level of serum glucose and serum lipids,and alleviate insulin resistance in NAFL patients.

This article defined a set of communication skills that are expected of second-year medical students conducting history and physical examinations on hospitalized patients.In order to teach the skills,an educational strategy was devised that included training sessions for medical teachers and the development of an innovative videotape tool used to train the teachers and their students.The majority of teachers and students felt that the educational design stimulated discussion and improved their understanding of communication skills.This useful teaching technique is transferable to other institutions.

Cancer cells can change metabolic pathways, including glycolysis and glutamine metabolism, and produce the raw materials needed for rapid proliferation and survival. Therefore, research on metabolic pathways of cancer cells might help find the targets of cancer therapy. In this review, we outlined the metabolic features of aerobic glycolysis, glutamine metabolism and (tricarboxylic acid) TCA cycle in cancer. We also described metabolic targets for cancer therapy and therapeutic agents for the corresponding targets in these metabolic pathways, and finally discussed some of the challenges related to tumor metabolism as a therapeutic target in cancer therapy.

Objective]To observe the clinical effect in treating cystic acne with combination of Yu Shi San Gen Tang and minocycline. [Methods] 120 patients with cystic acne were randomly divided into 3 groups,40 cases in treatment group treated with Yu Shi San Gen Tang and minocycline,40 cases in control group1treated with minocycline and 40 cases in the control group 2 treated with Yu Shi San Gen Tang.

Objective: To optimize the molding technology for Compound Yizhihao Dropping Pills. Methods: Box-Behnken central composite design was adopted; The matrix ratio, the ratio of extract to matrix, and dropping speed were taken as the independent variables; The weight variation of pills and general normalized value were taken as dependent variables. The response surface methodology (RSM) was used to estimate the relationship between the dependent and independent variables and to validate the optimal formulation. Then the differences of dissolution behaviors between the granule and dropping pills were investigated by in vitro dissolution test. Results: The optimized conditions were as follows: the ratio of PEG 4000 to PEG 6000 was 3.8:1, the ratio of extracts to matrix was 1:2.5, the dropping speed was 28 drops/min. Under these conditions, the measured value was consistent with the predicated value with RSD < 5%. The dissolution rates of dropping pills was significantly higher than those of the granule. Conclusion: The molding technology of dropping pills is optimized, which is simple and feasible.
