Objective To investigate the long-term results of amniotic membrane transplantation for conjunctival surface reconstruction and analyze the involved microsurgical techniques and associated factors. Methods Fifty-one consecutive cases (55 eyes) with symblepharon at degree due to eye burns or Stevens-Johnson syndrome were accepted amniotic membrane transplantation after lysis of symblepharon. Results Observation time varied from 36 to 44 months (mean value, 38?4 months). Fifty-six point four percent(31/55) eyes got enough conjunctival fornix and resolution of eye movement restrict. About sixteen percent of them (9/55) recurred less symblepharon. Fifteen-five eyes of them(27.3%) recurred moderate symblepharon. The results of AMT for those patients with symblepharon at different degree and between those patients who were performed in different time after eye burns had significant difference statistically ( ? 2 test, P

Objective To evaluate the use of amniotic membrane patches for mild or moderate eye burns at the stage of acute burns and the involved microsurgical techniques.Methods Thirty-four eyes with corneal burns of Ⅱ to Ⅲ degree in which may have partial limbal necrosis were accepted amniotic membrane patching (21 eyes) or pharmaceutical treatment (13 eyes).Four amniotic patches were procured and examined by transmitting electronic microscope when the exposed corneal surface became re-epithelialization after amniotic membrane inching.Results Amniotic patches became partially melting or prolapsed 5-10 (11± 2) days after surgery.The uncovered corneal surface showed quickly re-epithehalized.There were a few thin fibrovascular membrane invaded onto corneal surface in the patients with more than a half limbal necrosis.Postoperative visual acuity increased 1 to 6 (3.3 ± 1.2) lines.The electronic findings showed that most of the infiltrated polymorphonuclear neutrophils in the anmiotic patches became apoptosis.Corneal melting presented in four of 13 eyes who received only drug treatment and lamellar keratoplasty was then performed.The other eyes manifested pseudo-pterygium or symblepharon at different extent.Conclusion Amniotic,patches may reduce the inflammation of burned cornea and corneal neovascularization,accelerate re-epithelialization of corneal surface,even improve the rehabilitation of burned limbal stem cells.

Objective:To observe the influence of schisandrone on the levels of IL-1? and iNOS mRNA in the hippocampus of rats with Alzheimer-like disease(AD) and to investigate the probable prevention and therapy effect of schisandrone on AD. Methods: Totally 30 male SD rats, 8-12 weeks old, weighing 250-300 g, were randomly divided into 3 groups: blank control group,AD model group and schisandrone intervention group(n=10). The animal model of AD was established by 10 mmol/L amyloid-beta protein(A? 25-35 ) 5 ?l stereotactic injection into lateral cerebral ventricle of rats and the rats of schisandrone intervention group were administrated with corn oil with 1 mmol/L schisandrone. And then the levels of IL-1? and iNOS mRNA in the hippocampus were detected by RT-PCR. Results: The levels of IL-1? and iNOS mRNA in the hippocampus of rats with Alzheimer-like disease (0.333 7?0.122 3, 0.266 6?0.088 5) decreased obviously after administration of schisandrone (0.969 3?0.153 9, 0.666 0?0.121 1)(P

As a vital component in an overall laboratory animal care and use program , development of a disaster plan plays a critical role for every research institution .Currently, most of domestic institutions would draw up an“emergency operation plan , EOP”, but ignoring a practicable “business continuity plan , BCP” in establishing a disaster plan.In this article, we will discusse about the definition of disaster , how to set up an EOP, and how to establish a thorough BCP , in order to show an integrated and professional disaster plan in laboratory animal care and use program .

Objective To explore the value of strain rate and dobutamine stress echocardiography(DSE) in the diagnosis of coronary heart disease. Methods High-dose DSE was performed in 18 patients with coronary heart disease and 10 healthy persons, proved by selected coronary angiography. Ten patients had single coronary lesion, and the other 8 patients had more. By strain rate technology, systolic peak strain rate(SR_ SYS ) was measured in 12 segments of healthy persons and ischemic segments of patients. Results SR_ SYS of healthy subjects enhanced by the increasement of dose of DSE. In patients with single coronary lesion, SR_ SYS enhanced on the first states of baseline, 10 and 20 ?g?kg -1 ?min -1 ,while SR_ SYS changed non-significantly on 30 ?g?kg -1 ?min -1 , and began to decrease on 40 ?g?kg -1 ?min -1 . However in patients with more than one coronary lesions, SR_ SYS of 10 ?g?kg -1 ?min -1 became larger than that of baseline, while SR_ SYS didn't increase any longer on 20 ?g?kg -1 ?min -1 , and fell significantly on 40 ?g?kg -1 ?min -1 . Conclusions Combining stain rate and DSE to quantify local myocardial motion is valuable to offer many important clinic messages, and improves the diagnosis of coronary heart disease.

Background Mooren 's ulcer is an immune-related corneal inflammatory disease,and its pathogenesis remains below understood.Previous studies showed that the imbalance of T helper cell type 1 (Th1) and Th2 cell play important roles in the development of some autoimmune diseases.Thereby the influence of Th1/Th2 cells on the pathogenesis of Mooren's ulcer is being concerned.Objective This study was to investigate the change of Th1 and Th2 subsets in periphery blood of patients with active Mooren's ulcer.Methods Eleven consecutive patients with active Mooren's ulcer and 8 age-and gener-matched healthy controls were included in Zhongshan Ophthalmic Center,Sun Yat-sen University from January 2012 to July 2013 under the approval of Ethic Committee of this hospital and informed consent of each subject.The peripheral blood samples of all the subjects were obtained separately and periphery blood mononuclear cells (PBMCs)were isolated.The percentages of Th1 and Th2 in the PBMCs were assayed by flow cytometer.The relative expressions of T-bet mRNA,GATA-3 mRNA and signal transducer and activator of transcription 5 (Stat5) mRNA in the PBMCs were examined and compared by real-time fluorescence quantitative PCR (RT-qPCR) Results The percentage of Th1 cells in CD4+ T cells and Th1/Th2 value was 0.21％ (0.11％,0.31％) and 8.01 (4.49,12.01) respectively in the Mooren's ulcer group,which were significantly lower than 0.35％ (0.22％,0.71％)and 23.90 (22.49,33.49)in the normal control group,respectively (Z =-2.01,P =0.04 ; Z =-3.06,P =0.00).However,no significant difference was found in the percentage of Th2 between the two groups (Z=-1.98,P＞0.05).The relative expressions of T-bet mRNA and GATA-3 mRNA in PBMCs were significantly lower in the Mooren's ulcer group than those in the normal control group (Z =-3.47,-3.06,both at P=0.00) ;While the relative expression of Stat5 mRNA in PBMCs was insignificant changed between the two groups (Z =-1.05,P =0.33).Conclusions Th1 and Th2 cells are unbalanced in the active Mooren's ulcer patients.In addition,the down-expression of relevant transcription factors in peripheral blood also is seen in these patients.It is inferred that Th1 and Th2 cells may participate in the progress of Mooren's ulcer.

Objective To evaluate the effects of tofacitinib on liver function in rheumatoid arthritis (RA) patients.Methods Literature search was performed in databases including PubMed,Cochrane Library,China National Knowledge Infrastructure and Wanfang to identify randomized controlled trials about RA treated with tofacitinib.The retrieval time was up to August 2016.Meta-analysis was conducted by Revman 5.5 software.Results A total of 7 studies were included,involving 2 965 patients.The results of Meta-analysis revealed that the incidence of alanine transaminase (ALT)＞1 upper limit of normal (ULN) in patients receiving both 5 mg and 10 mg bid tofacitinib was significantly higher than placebo [5 mg bid tofacitinib:RR=1.48,95％CI (1.20,1.82),P=0.000 2;10 mg bid tofacitinib:RR=1.67,95％CI (1.37,2.05),P＜0.01];there was no significant difference in the incidence of ALT＞3 ULN [5 mg bid tofacitinib:RR=1.81,95％CI (0.57,5.79),P=0.32;10 mg bid tofacitinib:RR=1.36,95％CI (0.57,5.25),P=0.49];the incidence of aspartate transaminase (AST)＞1 ULN was significantly higher than placebo [5 mg bid tofacitinib:RR=1.59,95％CI (1.25,2.03),P=0.000 2;10 mg bid tofacitinib:RR=1.90,95％CI(1.50,2.40),P＜0.01],there was no significant difference in the incidence of AST＞3 ULN [5 mg bid tofacitinib:RR=1.17,95％CI (0.27,5.17),P=0.83;10 mg bid tofacitinib:RR=0.95,95％CI (0.26,3.44),P=0.94].Conclusion Tofacitinib slightly increases ALT and AST in patient with RA.Due to the limited sources and lack of domestic studies,more randomized controlled trials are still needed to verify the above conclusion.

Objective To test the effect of different flexion angles of knee joint on the myoelectric activity and torque of quadriceps femoris and hamstring muscle when these muscles contracting.MethodsElectromyographic activities and isometric torque measurements were performed on 10 healthy subjects at 30°, 60° and 90° of knee joint flexion.ResultsThe results indicated that the greatest maximal voluntary isometric contracture-torque of quadriceps femoris occurred during knee extension at 60° of knee flexion ( P<0.01). However, no significant relationship of maximal voluntary isometric contracture-electromyography and maximal voluntary isometric contracture-torque of quadriceps femoris were found in 10 subjects. But when knee joint was at 90° flexion, hamstring muscle had a greatest neuro-myoelectric activity.ConclusionThe exercise of maximal voluntary isometric contraction of quadriceps femoris and hamstrings muscles at certain knee joint angle can help to maintain the stability of knee joint.
