OBJECTIVE:To compare the effects of omeprazole and esomeprazole,two kinds of proton pump inhibitors,on clopidogrel platelet inhibition following cardiac stents implantation.METHODS:Totally 180 patients with coronary artery disease underwent percutaneous coronary intervention (PCI) at the Zhujiang Hospital of Southern Medical University from June 2008 to May 2009 were selected,including 83 males and 97 females.All patients were randomly divided into 3 groups,omeprazole + clopidogrel + aspirin group (OCA group,receiving omerprazole 20 mg/d),esomeprazole+clopidogrel+aspirin group (ECA group,receiving esomeprazole 10 mg/d),and control group (No proton pump inhibitor),with 60 patients in each group.In addition,all patients received a 300 mg clopidogrel and 0.1 g aspirin prior to PCI,and received 75 mg/d clopidogrel and 100 mg/d aspirin treatment for 1 week after PCI.Blood samples from patients were obtained from cubital vein before and at 1 week after adminstration,respectively.The vasodilator stimulated phosphoprotein phosphorylation state and platelet reactivity index (PRI) were calculated by flow cytometric assay.RESULTS:The PRI had no significant difference before administration (P>0.05),which was obviously decreased at 1 week after administration (P<0.05),especially lowest in the control and ECA groups (P<0.05).However,the PRI differences between the control and the ECA group had no significant (P>0.05).CONCLUSION:The administration of omeprazole rather than esomeprazole is associated with impaired clopidogrel platelet inhibition.Esomeprazole can be used as one of the preferred proton pump inhibitor in curing gastrointestinal bleeding caused by anti-platelet therapy following cardiac stents implantation.

Objective To increase externally-assigned response, improve energy response of CR39 and develop positive fast/thermal neutron personal dosimeter applicable for occupational exposure in oil and gas field logging by using pre-recoil layer.Methods The externally-assigned response of CR39 detector was improved through increasing the track density by using the α particle induced by the reaction of 10B(n,α) 7Li with the BN as pre-recoil layer, and the increase was vilified by using both Monte-Carlo simulation and experiment exposed by standard neutron source.Results Fast/thermal neutron personal dosimeter's neutron flux sensitivity and neutron dose equivalent sensitivity were 3.46 × 10-4 track per 0.013 and 52.8 mSv.According to theoretical derivation and experiment of standard 241 Am-Be neutron source, detecting efficiency and energy response of CR39 were effectively improved, and quantitative measurement of dose contributed by thermal neutron was realized.Conclusions CR39 fast/thermal neutron personal dosimeter of high sensitivity is applicable to oil and gas field logging environment and of potential development.

OBJECTIVETo study the therapeutic effects of posterolateral depression fractures of the tibial plateau through a modified anterolateral approach.

METHODSFrom February 2011 to January 2012,13 patients with posterolateral depression fractures of the tibial plateau were treated through a modified anterolateral approach. There were 8 males and 5 females, ranging in age from 28 to 59 years old (49.2 years old on average). Data from patients were collected retrospectively as follows: X-ray, time of fracture healing and the complications of fracture healing. The patients were evaluated both clinically and radiologically according to the Rasmussen score system.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months (mean 13.7 months). All the patients got bony union. The average radiographic bony union time was 15.1 weeks (ranged, 11 to 17 weeks). No case of secondary articular depression was found. No complications such as malunion or joint stiffness were found. But 1 patient had superficial infection and 1 patient had common peroneal nerve injury. According to the Rasmussen score system,the mean radiological score was 16.50 ± 0.67 (ranged, 13 to 18), and the mean functional score was 25.20 ± 2.21 (ranged, 13 to 30). The mean range of knee motion was (125.3 ± 9.3)° (ranged, 0° to 135°).

CONCLUSIONTreatment of depression fractures of posterolateral tibial plateau with a modified anterolateral approach is a safe method with effective exposure, due to its stable fixation and relatively good outcome with minimal soft-tissue complications. It is regarded as an ideal procedure for depression fractures of posterolateral tibial plateau.

OBJECTIVETo investigate the potential protective effect of the mitochondria-targeted antioxidant Mitoquinone (MitoQ) on post-thaw human sperm.

METHODSSemen samples were collected from 60 normal fertile men, each divided into six parts of equal volume to be incubated at 37 °C in normal saline (G0, control) or in the extender with 2 nmol/L (G1), 20 nmol/L (G2), 200 nmol/L (G3), 2 µmol/L (G4), and 20 µmol/L of MitoQ (G5). After one hour of incubation, the samples were subjected to computer-assisted semen analysis (CASA) for sperm motility, flow cytometry for reactive oxygen species (ROS), thiobarbituric acid assay for the concentration of malondialdehyde (MDA), and MitoTracker fluorescent staining and flow cytometry for the sperm mitochondrial membrane potential (MMP). Then, the semen were cryopreserved with none (B0), 200 nmol/L (B1), and 2 µmol/L of MitoQ (B2), followed by detection of the changes in the ROS, MDA, and MMP of the post-thaw sperm.

RESULTSThe percentage of progressively motile sperm and total rate of sperm motility were significantly higher in G3 ([30.8 ± 10.2]% and [70.6 ± 9.0]%) and G4 ([32.7 ± 13.5]% and [70.3 ± 11.9]%) than in G0 ([17.6 ± 5.0]% and [54.9 ± 11.5]%) (P < 0.05). The level of ROS dropped markedly with the increased concentration of MitoQ, 86.5 ± 31.6 in G3, 93.6 ± 42.0 in G4, and 45.1 ± 15.0 in G5, as compared with 160.8 ± 39.7 in G0 (P < 0.05). The content of MDA was remarkably lower in G3 ([0.9 ± 0.5] µmol/mg) and G4 ([0.9 ± 0.5] µmol/mg) than in G0 ([1.9 ± 1.1] µmol/mg) (P < 0.05), but not in G5 ([1.7 ± 0.7] µmol/mg), which was even higher than in G3 and G4 (P < 0.05). The MMP showed a significant reduction in G5 (1156 ± 216) in comparison with G0 (1701 ± 251) (P < 0.05) but exhibited no remarkable difference between G0 and G1 (1810 ± 298), G2 (1995 ± 437), G3 (1950 ± 334), or G4 (1582 ± 314). The percentage of progressively motile sperm and total rate of sperm motility after freezing-thawing were significantly decreased as compared with those of the fresh semen (P < 0.01), but both were remarkably higher in B1 ([3.2 ± 2.3]% and [ 43.0 ± 9.5]%) than in B0 ([0.8 ± 0.6]% and [26.5 ± 11.4]%) (P < 0.05). The ROS level was significantly lower in B1 and B2 than in B0 (34.6 ± 12. 3 and 37.0 ± 10.5 vs 56.9 ± 14.3, P < 0.05), and so was the MDA content ([1.4 ± 0.5] and [1.4 ± 0.6] µmol/mg vs [2.6 ± 1.0] µmol/mg, P < 0.05), but the MMP was markedly higher in B1 and B2 than in B0 (1010.0 ± 130.5 and 880.6 ± 128.6 vs 721.1 ± 24.8, P < 0.05).

CONCLUSIONAddition of MitoQ to the freezing extender at 200 nmol/L may effectively improve the quality of human sperm and MitoQ is a good protective addictive for human sperm cryopreservation.
