Myocardial ischemic preconditioning and postconditioning can reduce myocardial infarct size, improve myocardial contractility, protect coronary endothelial and myocardial cell ultrastructure, as well as reduce the incidence of arrhythmias. Clinical practice has confirmed the safety and efficacy of these two methods of myocardial protection. This paper reviewed about ischemic preconditioning and postconditioning protection mechanisms in myocardial ischemia reperfusion injury and clinical research literatures in recent years, to provide a theoretical basis for finding new treatment strategies on the prevention and treatment of ischemic cardiomyopathy.

A 56-year-old female patient of Han nationality presented with generalized erythema and vesicles for 6 days,as well as high fever for 2 days.Twenty days prior to hospitalization,the patient received surgical treatment combined with oral methazolamide and glucocorticoids for glaucoma.The patient had a history of allergy to sulfanilamides.On admission,the patient presented with generalized erythema,vesicles and occasional erosions with bilateral eyelid and oral involvement.Nikolsky's sign was positive.Wheezing sound was heard over the right lung.Genetic testing showed that HLA-B5901 allele was positive.The patient was diagnosed with methazolamide-induced toxic epidermal necrolysis (TEN) complicated by pneumonia,and managed with immunoglobulin (25 g/day,5 days),glucocorticoids (the largest dose equivalent to methylprednisolone 160 mg/day),fresh plasma,antibiotics,as well as other supporting and symptomatic treatments.The condition was controlled after 2 weeks,and the patient was cured and discharged from hospital after 25 days.The fact that the patient carried HLA-B5901 allele suggests that HLA-B5901 is strongly correlated with methazolamide-induced TEN or Stevens-Johnson syndrome in Chinese descendants or Han population,besides in Japanese and Korean descendants.

BACKGROUND: The occurrenceand development of rheumatoid arthritis were strongly associated with unbalance proliferation and apoptosis of synovial cells and lymphocytes. Some synovial cell apoptosis was abnormal. OBJECTIVE: To observe effects of heterogenic double umbilical cord blood stem cell transplantation on Bcl-2 and Bax expression in mice with type Ⅱcollagen-induced arthritis. METHODS: C57BL/6(H-2b) mice were induced with Freund's complete adjuvant and type Ⅱcollagen to establish mouse models of type Ⅱcollagen-induced arthritis.At 2days after secondary immunity incubation, mice were injected with saline via tail vein in the model and normal control groups. Umbilical cord blood hemopoietic stem cells were injected into mouse tail vein in the UBSCs transplantation groups (single dose:2×106/50 g; double dose: 1×106/50 g each, totally 2×106/50 g). Mice were intragastrically administrated methotrexate in the methotrexate positive control group, 0.017 5 g/kg once, once every 5 days, totally six times. RESULTS AND CONCLUSION: Joint tissue below knee and elbow was obtained at42 days following transplantation. Histopathology displayed that smooth and glossy articular surface, no inflammatory cell infiltration in the synovial layer and normal chondrocytes in the normal control group. Hyperplasia, a lot of inflammatory cell infiltration and damaged cartilage surface were visible in the model group. Slight hyperplasia and a little inflammatory cell infiltration were detectable in the methotrexate positive controlgroup and single UBSCs transplantation group. Double UBSCs transplantation group exhibited smooth and glossy articular cartilage surface, no damage, a little inflammatory cell infiltration. Immunohistochemistry demonstrated that Bcl-2 and Bax expression was lower in the double UBSCs transplantation group compared with single UBSCs transplantation group (P < 0.05). Compared with normal control group, no significant difference was detected (P > 0.05). Results suggest that double umbilical cord blood stem cells can induce synovial cell apoptosis in mice with type Ⅱcollagen-induced arthritis in a certain number and action time, and protect synovial membrane against damage.

BACKGROUND: Matrix metalloproteinase (MMP) degrades extracellular matrix, which is a necessity of joint destruction in rheumatoid arthritis patients. MMP-2 and MMP-9 can evaluate rheumatoid arthritis and serve as an index to predict progressive destruction of the joint. OBJECTIVE: To observe heterogenous allogeneic umbilical cord blood stem cell (UBSC) transplantation on MMP-2 and MMP-9 expression in the spleen of mice with type Ⅱ collagen-induced arthritis. METHODS: Fetus cord blood was sterilely obtained and cord blood stem cells were separated. The C57BL/6(H-2b) mice were assigned to five groups (n=10). Except normal control group, models of collagen-induced arthritis were established using complete Freund's adjuvant + type Ⅱ collagen. Mice from the methopterin group were intragastrically administered methopterin suspension 0.017 5 g/kg, once every 5 days. Other groups used caudal vein injection. Mice from the model and normal control groups were injected with saline. Mice from the mono-UBSCs group and double-UBSCs group were injected with 2×106/kg UBSCs from one and two parents. At 42 days following injection, animals were sacrificed and the ankle joint was obtained for histopathological detection. MMP-2 and MMP-9 mRNA expression in the spleen was examined using reverse transcription-polymerase chain reaction. RESULTS AND CONCLUSION: Double-UBSC transplantation could significantly inhibit inflammatory cell infiltration in synovial tissue of mice with type Ⅱ collagen-induced arthritis, repaired impaired cartilage tissue. The repair effect was better than that in methopterin group and mono-UBSCs group. MMP-2 and MMP-9 mRNA expression in the spleen was significantly lower in the double-UBSCs group than the mono-UBSCs group (P < 0.01). These suggest that heterogenous allogeneic double-UBSCs transplantation participated in pathological changes in rheumatoid arthritis cartilage and in synthesis of cartilage extracellular matrix and effectively treated rheumatoid arthritis by regulating MMP-2 and MMP-9 mRNA expression.

Objective Through the detection of the levels of serum betatrophin,anthropometric and biochemical indices,to determine the alteration of betatrophin levels in patients with polycystic ovary syndrome (PCOS) and the relationship between betatrophin levels and metabolic indexes such as 25-hydroxy vitamin D3 [25 (OH) D3].Methods The study group was composed of 24 women with PCOS and 20 age-natched healthy women as controls.Following general physical examination of the subjects,anthropometrie measurements were performed (height,weight,waist circumference,hip circumference).Body mass index (BMI) and waist-hip ratio were calculated;25 (OH) D3,Ca2+,fasting blood glucose,fasting insulin,triglycerides,high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C) were also measured and homeostasis model assessment of insulin resistance (HOMA-IR) were evaluated in all subjects.Serum betatrophin levels were examined with an enzyme-linked immunosorbent assay (ELISA).Using independent sample T test to compare the differences between groups,the linear correlation analysis was performed to study the correlation of betatrophin with anthropometric and biochemical indices,the influencing factors of betatrophin were analyzed by multiple linear regression.Results Circulating betatrophin levels [(0.341±0.034) ng/ml vs.(0.810±0.162) ng/ml,t=4.271,P<0.001] and HDL-C [(1.014±0.321) mmol/L vs.(1.419±0.287) mmol/L,t=2.218,P<0.05] significantly decreased in women with PCOS compared with controls,and BMI [(27.691±4.392) kg/m2 vs.(23.310±4.781) kg/m2,t=-2.073,P<0.05],fasting blood glucose [(5.950±0.411) mmol/L vs.(4.883±0.314) mmol/L,t=-2.142,P< 0.05],HOMA-IR [(4.946 ± 0.741) vs.(3.387± 0.397),t=-2.493,P<0.05],triglycerides [(1.510± 0.848) mmol/L vs.(1.037±0.402) mmol/L,t=-2.223,P<0.05],LDL-C [(3.431±0.479) mmol/L vs.(2.396±0.435) mmol/L,t=-2.433,P<0.05] were obviously increased.Moreover,there was a postive correlation between betatrophin and HOMA-IR (r=0.425,P<0.05) as well as 25(OH)D3 (r=0.577,P<0.05) and Ca2+ (r=0.448,P<0.05),while the betatrophin was negatively related to BMI (r=-0.451,P<0.05),triglycerides (r=-0.454,P<0.05),LDL-C (r=-0.551,P<0.05).Circulating betatrophin levels were higher when 25 (OH) D3 levels were beyond 35 nmol/L in PCOS patients [(0.539±0.092) ng/ml vs.(0.199±0.031) ng/ml,t=3.072,P<0.001],and the multiple linear regression analysis showed that the main factors affecting the levels of betatrophin were BMI (OR=-0.260),HOMA-IR (OR=0.218),25(OH)D3 (OR=0.238),and glycerol (OR=-0.162).Conclusion It is speculated that betatrophin may be a valuable predictive factor of PCOS because betatrophin is closely associated with insulin resistance,lipid metabolism disorders and the lack of 25-hydroxy vitamin D3 in PCOS patients.
