BACKGROUND:Taurine is an important non-enzymatic system antioxidant in the lens.The mechanism of its anti-oxidative effect is mainly to protect lens from oxidative injury by anti-lipid peroxidation.OBJECTIVE:This study was to observe the effect of exogenous taurine on lens epithefial cell apoptosis-induced by H2O2 in vitro.DESIGN:A randomized controlled animal experiment.SETTING:Department of Ophthalmology,Affiliated Hospital of Qingdao University Medical College.MATERIALS:Seventy-five adult New Zealand standard tabbits,of either gender,weighing 1.5-2.5 kg,were provided by Qingdao Laboratory Animal Center.Reagent kit for in situ detecting cell apoptosis(Sigma Company,USA),taurine and H2O2(Shanghai Guangda Chemical Reagent Factory,China)were included in this study.METHODS:This study was performed in the Department of Ophthalmology and Central Laboratory.Affiliated Hospital of Qingdao University Medical College from Mav 2005 to June 2007.Rabbit lenses were harvested and randomly divided into 3 groups:control group,in which,clear lenses were incubated in non-serum and non-phenolsulfonphthalein MEM medium which was renewed every 24 hours,H2O2 group,in which,clear lenses were incubated in non-serum and non-phenolsulfonphthalein MEM medium containing 1 mmol/L H2O2 with addition of 62 μL H202(30 g/L)every 6 hours,and H2O2+taurine group,in which,clear lenses were incubated in non-serum and non-phenolsulfonphthalein MEM medium containing 1 mmol/L H2O2 and 10 g/L taurine.which was renewed every 6 hours.The protocol was conducted in accordance with ethical guidelines for the use and care of animals.MAIN OUTCOME MEASURES:Observation of lens opacity 6.12,24.48 and 72 hours after culture;Lens epithelial cell apoptosis determined by DNA in situ end labeling and DNA fragment analysis.RESULTS:Lens opacity:The lens opacity in the H2O2 group was aggregrated gradually along with the time of oxidative injury.The lens opacity in the H2O2 group was severer than that in the H2O2+taurine group.Lens epithelial cell apoptosis:There were no apoptotic cells in the control group within 72 hours.The number of apoptotic cells in the H2O2 group was increased gradually with the prolonged time of oxidative injury.Till the 72nd hour,the cells were all tamed into apoptotic cells.A few aopototic celIs were found in the H2O2+taurine group since hour 24,and then were more and more,and the number of apoptotic cells accounted for about 30%at hour 72.The apoptotic rate in the H202+taurine group was significantly lower than that in the H2O group at each time point(q=8.6845,P＜0.01).There was no significant difference in apoptotic rate between the H202+taurine group and the control group (P＞0.05). Findings of DNA fragmentation assay:The DNA"ladder"was found in the H2O2 group at hours 24,36,48 and 72,while no DNA"ladder"but only normal electrophoresis straps were present in the other two groups 24 hours after culture.CONCLUSION:Taurine can inhibit the oxidative injury-induced apoptosis of rabbit lens epithelial cells,and alleviate lens opacity.

Objective To investigate the effects of lactoferrin on activity of PKG in spinal dorsal horn in a rat model of neuropathic pain(NP).Methods Thirty-two male SD rats weighing 200-250 g were randomly divided into4 groups(n = 8 each): sham operation group(group S),NP group,lactoferrin group and KT5823(an inhibitor of PKG)group.Neuropathic pain was produced by placing loosely constrictive ligatures around the common sciatic nerve in group NP,lactoferrin and KT5823,while the sciatic nerve was only exposed but not ligated in groupS.In group S and NP,normal saline 10 μl + 50% dimethyl sulfoxide(DMSO)10 μl were injected intrathecally.Lactoferrin 100 μg + 50% DMSO 10 μl were given intrathecally in group lactoferrin.Lactoferrin 100 μg + KT5823 10 μl were given intrathecally in group KT5823.The paw withdrawal latency(PWL)to a thermal nociceptive stimulus was measured every 30 min within 180 min after administration.The rats were then sacrificed and the spinal cord was removed.The activity of PKG in the spinal dorsal horn was determined by immunofluorescence.Results Compared with group NP and KT5823,the PWL was significantly prolonged after administration in group lactoferrin and the PKG activity was significantly increased in group lactoferrin(P ＜ 0.05).There was no significant difference in the parameters mentioned above between group NP and group KT5823(P ＞ 0.05).Conclusion Lactoferrin reduces NP by inhibiting the activity of PKG in spinal dorsal horn in rats.

Recent studies demonstrate that the long non-coding RNAs (lncRNAs), pseudogenes, circular RNAs (circRNAs) and so on can be used as competitive endogenous RNAs (ceRNAs), binding to microRNAs (miRNAs), to regulate the expression level of their targets.This novel interplay optimizes traditional liner miRNA→RNA pattern and has become a research hotspot in the scientific community.Dysregulation of ceRNA interplay will influence the body′s normal life activities, leading to the occurrence of diseases, and even tumor formation.This article briefly introduces the key components of ceRNA crosstalk and its research progress in gastric cancer pathogenesis, so as to provide a new thought for cancer research, clinical diagnosis and therapeutics.

OBJECTIVETo compare the clinical therapeutic effects between ozone and triamcinolone acetonide for the treatment of mild meniscal injury.

METHODSFrom January 2008 to December 2012, 119 patients with meniscal injury diagnosed as type I or II by MRI were divided into three groups. In the triamcinolone acetonide (A) group, there were 38 males and 2 females, with an average age of (25.34 +/- 6.34) years old, ranging from 18 to 48 years old; 36 patients had single knee injuries, 4 patients had double knee injuries and 44 knees with joint effusion. In the ozone (B) group,there were 37 males and 2 females, with an average age of (26.98 +/- 7.20) years old, ranging from 19 to 50 years old; 33 patients had single knee injuries, 6 patiens had double knees injuries and 40 knees with joint effusion. In the combination of ozone and triamcinolone acetonide (C) group, there were 37 males and 3 females,with an average age of (26.44 +/- 6.38) years old, ranging from 18 to 47 years old; 33 patients had single knee injuries, 7 patients had double knees injuries and 39 knees with joint effusion. The patients were treated with injection of 3 mg triamcinolone acetonide alone, 30 ml (30 microg/ml) ozone alone, or both two drugs respectively in knee joint cavity. All the treatment methods were carried out weekly and 4 times injections were required for a treatment course. Knee joint function was evaluated by Lysholm scale and knee joint effusion was examined by MRI before and after treatment.

RESULTSThe scale of knee joint function was 35.68 +/- 4.15 and 65.55 +/- 7.66 in group A, 36.35 +/- 6.83 and 74.39 +/- 8.47 in group B, 36.62 +/- 6.03 and 95.47 +/- 4.78 in group C before and after treatment. Compared with that before treatment, the total scale of knee joint function improved after treatment in every group. The total scale of group C was better than that of the other groups after the treatment,but there was no significant difference between group A and group B. The effective rate of these drugson joint effusion was 68.18% in group A, 62.5% in group B and 87.18% in group C. The effect of co-injection on joint effusion in group C was significantly better than that of triamcinolone acetonide or ozone alone, but the difference between group A and group B was not significant.

CONCLUSIONOzone and triamcinolone acetonide are effective in the treatment of mild meniscal injury, which can relieve symptoms and promote the recovery of joint function. Campared with the single injection, the combination of ozone and triamcinolone acetonide is better.

Objective: To compare the effects of pericardium patch aortoplasty and pulmonary patch aortoplasty for treating the infants with aorticcoarctation (AC) combining hypoplastic aortic arch in order to provide a better surgical choice in clinical practice.
Methods: A total of 57 patients with AC combining hypoplastic aortic arch treated in our hospital from 2009-01 to 2014-12 were retrospectively studied. The patients were divided into 2 groups: Pericardium patch aortoplasty group,n=26 and Pulmonary patch aortoplasty group,n=31. The changes of the pressure gradient at post-operation and follow-up period were compared.
Results: There were 2/57 (3.5%) patients died, 1 in Pericardium patch aortoplasty group by pulmonary hypertension crisis, the other 1 in Pulmonary patch aortoplasty group by respiratory distress syndrome. No renal failure or neurological complication occurred in neither groups. The cardiopulmonary bypass time, aortic clamping time, ventilator time and ICU stay time were similar between 2 groups,P>0.05. Selective cerebral perfusion time in Pericardium patch aortoplasty group was shorter than Pulmonary patch aortoplasty group (30.5 ± 8.6) s vs (35.6 ± 10.3) s,P<0.05. By ultrasound estimation, the post-operative AC pressure gradients were decreased than they were before, as in Pericardium patch aortoplasty group (9.5 ± 7.5) mmHg vs (39.9 ± 15.5) mmHg and in Pulmonary patch aortoplasty group (11.8 ± 11.3) mmHgvs (39.2 ± 14.5) mmHg, bothP<0.05; while post-operative pressure gradients were similar between 2 groups,P>0.05. Follow-up study was conducted in 51 patients for (17.6 ± 16.6) months, Pericardium patch aortoplasty group had 6 patients with re-stenosis, 3 of them would receive balloon angioplasty and 3 would be continuously followed-up; Pulmonary patch aortoplasty group had 6 patients with re-stenosis, 2 of them ifnished balloon angioplasty and their pressure gradients were obviously decreased, 4 would be continuously followed-up. Kaplan-Meier curves presented that Pulmonary patch aortoplasty group was superior to Pericardium patch aortoplasty group in re-stenosis occurrence during follow-up period.
Conclusion: Both pericardium patch aortoplasty and pulmonary patch aortoplasty were effective for treating the patients with AC combining hypoplastic aortic arch, the early post-operative efifcacy was similar, while the mid-term follow-up result was better in pulmonary patch aortoplasty.

Objective: To summarize the early- and med-term outcomes of modified Fontan operation in patients with functional single ventricle and separate hepatic venous (SHV) drainage. Methods: A total of 39 patients with functional single ventricle and SHV drainage received modified Fontan operation in our hospital from 2009-01 to 2015-12 were retrospectively analyzed. There were 26 (66.7%) male, the average age was (6.98±3.62) years, body weight was (20.79±9.66) kg and pre-operative mean pulmonary artery pressure was (9.77±2.51) mmHg. Based on if SHV combining Apicocaval Juxtaposition (ACJ), the patients were divided into 2 groups: SHV group,n=29 and SHV+CAJ group,n=10. The early (3 months) - and med (5 years)-term post-operative outcomes were analyzed. Results: General clinical data was similar between 2 groups,P>0.05. There were 20/39 patients with one-stage operation, 19 with two-stage operation (18 after Glenn operation and 1 after B-T operation). Modified Fontan operation method was mainly used extracardiac conduit-common open technique (30 patients, 76.9%). 19 patients had CPB with aorta clamping, CPB time was 72-446 (189.74±84.96) min and aorta clamping time was 26-171 (89.05±43.96) min; the other 19 patients had CPB without aorta clamping, CPB time was 60-209 (109.99±98.86) min. 10 patients received re-surgery due to early post-operative complications. 3 patients died at early post-operation with the mortality at 7.7%. The average follow-up time was 3.9 (0.83-7.17) years, 1 patient had cardiac function at NYHA II and the others at NYHA I; the 5-year survival rate was 100%. Conclusion: The early- and med-term outcomes of modified Fontan operation were good in patients with functional single ventricle and SHV drainage. Selection of modified Fontan operation method should be based on the distance form inferior vena cava to SHV and presence of ACJ.
