Objective: To assess the risk factors for peri-procedural myocardial infarction (PMI) occurrence in patients after percutaneous coronary intervention (PCI) based on the new standard of US Society for cardiovascular angiography and interventions (SCAI). Methods: According to SCAI standard, a total of 3371 relevant patients with 3516 elective PCI in our hospital were enrolled. The baseline clinical features, coronary angiography (CAG) findings and PCI procedural elements were retrospectively studied, the independent risk factors for PMI occurrence were identified by multivariate Logistic regression analysis. Results: There was 108/3516 (3.1%) PMI occurred in all patients. Multivariate Logistic regression analysis presented that age (OR=1.037, 95% CI 1.016-1.058), treating multi-vessel lesions (OR=1.697, 95% CI 1.095-2.629), treating at least 1 bifurcation lesion (OR=1.869, 95% CI: 1.213-2.878) and the total length of lesion (OR=1.016, 95%CI 1.009-1.024) were the independent risk factors for PMI occurrence. Conclusions: Age, treating multi-vessel lesions, at least one bifurcation lesion and the total length of lesion were the independent risk factors for PMI occurrence in patients after elective PCI.

It has been suggested that melatonin is involved in learning and memory. In the present study, we investigated the effects of melatonin on spatial learning and memory in rats, using Morris water maze and electrophysiological methods. The results are as follows. (1) During a six-day water maze training, the mean escape latency of melatonin group in the last 4 days was 30.02+/-3.6 s, and that of control group was 18.44+/-2.7 s (P<0.01). The crossing annulus coefficient of melatonin group was 25.68+/-2.32%, and that of control group was 43.33+/-2.85% (P<0.01). (2) Microinjection of melatonin into CA1 area inhibited long-term potentiation (LTP). Sixty minutes after tetanus, the field excitory postsynaptic potentials (fEPSP) slope of group C (n=7 0.5 microliter saline) was 169.71+/-6.48 % of the baseline, and that of group M2 (n=6, 2 microgram melatonin) was 114.28+/-1.80% of the baseline. The difference is significant (P<0.01). (3) We also investigated the effects of melatonin on LTP after administration of scopolamine. Sixty minutes after tetanus, the fEPSP slope of group SM (n=6, 2 microgram scopolamine before 2 microgram melatonin) was 113.70+/-5.55% of the baseline. It showed a significant decrease compared with group C (P<0.01). However, there was no difference between groups SM and M2 (P>0.05, i.v.). The results obtained by applying melatonin after bicuculline were different from those after scopolamine. Sixty minutes after tetanus, the fEPSP slope of group BM (n=7, 1 microgram bicuculline before 2 microgram melatonin) was 162.29+/>10.52% of the baseline. Compared with group C, there is no significant difference (P>0.05); but compared with group M2, the difference is significant (P<0.01). Our results showed that application of melatonin in rats significantly inhibited not only spatial learning and memory, but also LTP in CA1 area. Furthermore, the results indicate that the inhibition of LTP by melatonin may not be mediated by cholinergic system, but may be through the modulation of GABAergic system.

Objective: To observe the effect of amlodipine on bone marrow endothelial progenitor cell (EPC) mobilization, neo-vascularization and cardiac function in diabetic rats after myocardial infarction (MI) with the possible mechanisms.
Methods: A total of 60 male SD rats were divided into 2 groups. Normal group, n=20. Diabetic group, n=40, the rats were fed with high fat diet (HFD) for 4 weeks and then received streptozotocin followed by left anterior descending coronary artery ligation to establish MI model, those rats were further divided into 2 sub-groups:Control group, the rats received sodium carboxymethylcellulose 1 ml/day with HFD and Treatment group, the rats received amlodipine 2 mg/kg/day with HFD, n=20 in each sub-group, all animals were treated for 4 weeks. The EPC level in peripheral blood CD45-/low+/CD133+/KDR+ at before and 1, 3, 5, 7, 14, 28 days after operation were examined by lfow cytometry, plasma vascular endothelial growth factor (VEGF) level was measured by ELISA, capillary density in MI area was determined by CD31 staining, EPC related protein expressions were detected by western blot analysis and the cardiac function was evaluated by echocardiography.
Results: EPC in CD45-/low+/CD133+/KDR+in Treatment group at 7 days after operation was increased than Control group at 5 days after operation (112 ± 30/106) vs (55 ± 10/106), plasma VEGF in Treatment group was higher than Control group (5.63 ± 1.33) ng/L vs (3.68 ± 0.98) ng/L; Treatment group presented increased expressions of protein kinase B, endothelial nitric oxide synthase (eNOS) and matrix metallopeptidase-9, increased capillary density in MI area, higher LVEF and left ventricular fractional shorting, all P<0.05-0.01.
Conclusion: Amlodipine improves EPC mobilization, neo-vascularization and cardiac function in diabetic-MI rats, it may be related to VEGF/eNOS cascade activation.

Objective:To explore the influence of selective fetoscopic laser occlusion of chorioangiopagous vessels (FLOC) versus Solomon surgery in the management of twin-to-twin transfusion syndrome (TTTS) on procedure-related complications, fetal survival rate, and residual anastomoses.Methods:A total of 59 pregnant women with TTTS who underwent FLOC in the Third Affiliated Hospital of Zhengzhou University from May 2018 to March 2020 were retrospectively enrolled and divided into Solomon ( n=33) and selective FLOC groups ( n=26) based on the FLOC operation method. Placentae of 25 pregnant women (15 in the Solomon group, 10 in the selective FLOC group) with both survival twins were perfused to observe the type and diameter of the residual anastomoses. Fetal survival rate, procedure-related complications, and the type and diameter of residual anastomoses were analyzed and compared between the two groups using two independent samples t-test, Mann-Whitney U test, χ2 test and Fisher's exact test. Results:(1) The operating time of Solomon was shorter than that of selective FLOC [74 min (60-90 min) vs 95 min (81-123 min), Z=2.906, P=0.004]. But no statistically significant differences in the gestational week at operation, time of pregnancy end, and the interval between operation and pregnancy end was observed between the two groups (all P>0.05). (2) There was no statistically significant difference in the survival rate of both twins, one fetus, at least one fetus, and the incidence of postoperative twin anemia-polycythemia sequence (TAPS) and recurrent TTTS in the Solomon group and selective FLOC group [64%(21/33) vs 50%(13/26), χ2=1.107; 15%(5/33) vs 35%(9/26), χ2=3.044; 79%(26/33) vs 85%(22/26), χ2=0.326; 3%(1/33) vs 12%(3/26), χ2=1.368; 0% (0/33) vs 4%(1/26), χ2=1.118; all P>0.05]. (3) There was no statistically significant difference in the number of placentae with residual anastomoses or the number of artery-to-vein, vein-to-artery, artery-to-artery, and vein-to-vein anastomoses between the two groups (7/15 vs 6/10, 2/8 vs 4/15, 3/8 vs 4/15, 2/8 vs 5/15, 1/8 vs 2/15; Fisher's exact test, all P>0.05), but the diameter of the residual anastomoses in the Solomon group was smaller than that in the selective FLOC group [(0.8±0.3) and (2.2±0.7) mm, t=0.764, P=0.034]. (4) Among the four pregnant women developed TAPS after operation, one patient had two residual artery-to-vein anastomoses in the placenta with diameter of 0.54 mm and 0.43 mm, respectively; one patient had one artery-to-vein anastomosis with a diameter of 0.64 mm; one had one artery-to-artery and one vein-to-vein anastomosis with diameter of 1.56 mm and 1.89 mm, respectively. Conclusions:Compared with selective FLOC, Solomon surgery can reduce the vessel diameter of residual anastomoses in women with TTTS, but does not reduce postoperative complications, nor improve the pregnancy outcomes.

Osteoarthritis (Osteoarthritis, OA) is a common clinical degenerative joint disease with increased incidence rate in recent years. Animal experiment is one of the important ways to explore pathogenesis and treatment of OA, while induced animal model is the most important part in animal experiment. Intra-articular injection of drugs is a classical method for establishing animal model of OA. Choose of animal should follows the principle of correlation, appropriateness and practicability, injections should perform in accordance with experimental purposes and subject, detections means and evaluation methods also should corresponding to experimental reality. The gold standard of OA animal model and intra-articular injections has not build, need further study.
