Objective To evaluate the role of delta and kappa opioid receptors in sufentanil preconditioning (SPC)-induced attenuation of myocardial ischemia-reperfusion (I/R) injury in rats.Methods Forty adult male Sprague-Dawley rats,aged 2-3 months,weighing 250-330 g,were randomly divided into 5 groups (n =8 each) using a random number table:sham operation group (group S),group I/R,group SPC,δ receptor antagonist naltrindole + SPC group (NTD + SPC group),and κ receptor antagonist nor-binaltorphimine (nor-BNI) + SPC group (BNI + SPC group).Myocardial I/R was induced by 30 min occlusion of left anterior descending branch of coronary artery followed by 120 min reperfusion.In group SPC,5 min infusion of sufentanil 3μg/kg was repeated 3 times at 5 min interval before myocardial ischemia.In NTD + SPC group,naltrindole 5 mg/kg was intravenously injected,at 10 before SPC.In BNI + SPC group,nor-BNI 5 mg/kg was injected intravenously at 15 min before SPC.Arterial blood samples were collected at 120 min of reperfusion for measurement of the serum cardiac troponin I (cTnI) and creatine kinase isoenzyme-MB (CK-MB) concentrations.The rats were then sacrificed and hearts removed for determination of myocardial infarct size (IS) and area at risk (AAR).IS/AAR ratio was calculated.Results Compared with S group,the serum cTnI and CK-MB concentrations were significantly increased in I/R,NTD + SPC and BNI + SPC groups,and the serum CK-MB concentrations were increased in SPC group,and IS/AAR ratio was increased in I/R group (P ＜ 0.05 or 0.01).The serum cTnI and CK-MB concentrations were significantly lower in SPC,NTD + SPC and BNI + SPC groups and IS/AAR ratio was lower in SPC and BNI + SPC groups than in I/R group,and higher in NTD + SPC and BNI + SPC groups than in SPC group (P ＜ 0.05 or 0.01).Conclusion Both κ and δ opioid receptors mediate SPC-induced attenuation of myocardial I/R injury in rats.

Objective To observe the early clinical efficacy of PFC fixed platform and RP rotating platform prosthesis two kinds of artificial knee replacement system for the treatment of knee osteoarthritis.Methods 39 cases (39 knees)with knee osteoarthritis were treated with total knee arthroplasty(TKA).According to intraoperative use of different types of prosthesis,the cases were divided into two groups:fixed platforms group 16 cases and rotating platform group 23 cases.The wound healing,patients with gait and knee activity after operation were observed.Results Three cases took place postoperative deep vein thrombosis,after conservative treatment,the symptoms improved and discharged,two cases of postoperative wound fat liquefaction,by dressing wound healing,time stitches discharged.3 to 12 months follow-up visit(average 10 months),all patients could walk uptight without noticeable limp.Last follow-up group,fixed platforms,rotating platform group Knee Score (HSS) and knee activity (ROM) were (83.17 ± 7.12),(81.32 ± 5.39) points and (109.73 ± 6.35) °,(103.12 ± 4.28) °,compared with the preoperative differencewasstatisticallysignificant (AgroupHSS:t =22.10,ROM:t =9.21 ; BgroupHSS:t =30.69,ROM:t =9.54,all P ＜ 0.01),but the difference between groups was not statistically significant(HSS:t =0.88,ROM:t =3.63,all P ＞ 0.05).Conclusion Using PFC and RP prosthesis after total knee replacement system in early has a good effect,both of which improve joint function early with no significant difference,but long-term effects need further observation.

Objective:To investigate the effects of maternal malnutrition on the expression of the insulin signal transduction proteins in the liver of perinatal rats.Methods:(1)The dams were semi-starvation from the first day during pregnancy to build the animal model of intrauterine growth retardation(IUGR).On days 15,17,19,21(E15,E17,E19,E21)of gestation,the fetuses were delivered by cesarean section.The fetal rats,placenta,fetal liver and the fetal brain were weighed respectively.And the placenta weight to the body weight ratio(PWR),the liver weight to the body weight ratio(LWR),the brain weight to the body weight ratio(BWR)were calculated;The expressions of the hepatic insulin receptor(IR),insulin receptor substrate-1(IRS-1),insulin receptor subtrate-2(IRS-2),phosphatidyl inositol 3-kinse(PI3K)mRNA in the rats during perinatal period were detected by RT-PCR.Results:(1)The PWR of the IUGR fetus on E15 was lower than that in the control(P0.05).Conclusion:(1)In order to protect the development of brain,the fetus that suffered maternal malnutrition throughout the pregnancy had liver weight and body weight reduced much more than brain weight,which was known as "brain spare effects".(2)The expressions of hepatic IR mRNA and PI3K mRNA of the fetus were in normal ranges;But the expressions of the hepatic IRS-1 mRNA and IRS-2 mRNA of the IUGR fetus were decreased during the perinatal period.These may be related to the growth retardation and insulin resistance of the adult IUGR rats.

Objective:To investigate the expressions of the insulin receptor(IR),insulin receptor substrate-1(IRS-1),insulin receptor substrate-2(IRS-2),phosphatidyl inositol 3-kinase(PI3K) and insulin-like growth factor-1(IGF-1) of the livers of the male adult rats born with intrauterine growth retardation(IUGR),and to find out the relationship between IUGR and insulin resistance in their adult life.Methods:The foods were available ad libitum throughout the pregnancy to the control group and the rats in the experimental group were fed 50% of the control group to build the IUGR animal model.Liver samples were collected when the male offspring grew up to 12 weeks old.The mRNA expressions of hepatic IR,IRS-1,IRS-2,PI3K,and IGF-1 were detected by RT-PCR.The protein expressions of hepatic IR,IRS-1,and IRS-2 were analyzed by immunohistochemistry.Results:The mRNA expressions of hepatic IR in the adult male rats with IUGR were significantly lower than control group[(0.41?0.06) vs(0.62?0.11),P0.05] in both groups.The mRNA and protein expressions of the hepatic IRS-1[mRNA:(0.77?0.20) vs(1.32?0.42),P0.05].The expressions of hepatic IGF-1 mRNA of the rats with IUGR were significantly lower than those in control group [(0.55?0.12) vs(1.22?0.34),P

BACKGROUND:Polycaprolactone as a polymer material has poor biocompatibility, and needs to be combined with other natural biological materials to increase biocompatibility, thereby promoting tissue regeneration.OBJECTIVE:To develop a novel honeycomb-like polycaprolactone-calcium silicate crystal compound scaffold, and observe its osteogenic effects in Sprague-Dawley rats with skull defects.METHODS: Eighteen Sprague-Dawley rats were used to make skull defect models and randomized into three groups: blank control group with no implantation, control group with implantation of normal polycaprolactone-calcium silicate crystal compound scaffold, and experimental group with implantation of the novel honeycomb-like polycaprolactone- calcium silicate crystal compound scaffold. Six weeks after implantation, bone regeneration effect in the defect region measuredvia X-ray scanning, Micro-CT three-dimensional reconstruction, and histological analysis.RESULTS AND CONCLUSION: (1) X-ray scan: in all the rats, the size of bone defect was reduced, the fracture line became vague, and the marginal bone density was increased. The percentage of new bone area was highest in the experimental group, successively followed by the control group and blank control group. (2) Micro-CT three-dimensional reconstruction: new bones in the blank control group were mainly distributed on the both sides of the defect, but those in the control and experimental groups distributed in the defect region. The bone regeneration capacity was ranked as follows: experimental group > control group > blank control group (P < 0.05). (3) Histological analysis: new bone ingrowth was visible in all the three groups to different extents. Compared with the other two groups, new bone formation and microvessel density were significantly higher in the experimental group (P < 0.05). To conclude, this novel honeycomb-like polycaprolactone-calcium silicate crystal compound scaffold can obviously promote bone formation in the skull defect region.
