Objective To evaluate the relationship between DJ?1 and diabetes mellitus ( DM )?caused influence on cardioprotection induced by ischemic postconditioning in rats. Methods Adult male Sprague?Dawley rats, aged 3 months, weighing 220-250 g, were used in the study. DM was induced by intraperitoneal injection of 1% streptozotocin 60 mg∕kg and confirmed by blood glucose≥16.7 mmol∕L. Forty?eight rats with DM were randomly divided into 3 groups ( n=16 each) using a random number table:sham operation group ( group DM?S ) , myocardial ischemia?reperfusion ( I∕R ) group ( DM?IR ) and ischemic postconditioning group (DM?IPO group). Another 48 normal rats received the equal volume of citrate buffer solution instead and served as control. Those rats were randomly divided into 3 groups ( n=16 each) using a random number table: sham operation group ( S group) , myocardial I∕R group ( IR group) and ischemic postconditioning group (IPO group). At 12 weeks after streptozotocin injection, myocardial I∕R was produced by 30 min occlusion of the left anterior descending branch of the coronary artery followed by 120 min reperfusion. Ischemic postconditioning was induced by 3 cycles of 10 s reperfusion followed by 10 s limb ischemia at the end of 30 min limb ischemia. At 120 min of reperfusion, the animals were sacrificed, and hearts were removed for determination of myocardial infarction size ( using TTC ) , and expression of DJ?1, phosphatase and tensin homologue ( PTEN) protein, and phosphorylated Akt ( p?Akt) in myocardial tissues ( by Western blot) . Results The infarction size was significantly increased in diabetic and nondiabetic rats during myocardial I∕R. The expression of DJ?1, PTEN protein and p?Akt was significantly higher during myocardial I∕R in nondiabetic rats, and the expression of PTEN protein and p?Akt was up?regulated, and no significant change was found in DJ?1 expression during myocardial I∕R in diabetic rats. Ischemic postconditioning reduced infarction size during myocardial I∕R and up?regulated the expression of DJ?1 and p?Akt, and down?regulated the expression of PTEN protein in nondiabetic rats, but not in diabetic rats. Compared with nondiabetic rats, the expression of DJ?1 and p?Akt was down?regulated, and the expression of PTEN protein was up?regulated after ischemic postconditioning in diabetic rats. Conclusion The mechanism by which DM abolishes cardioprotection induced by ischemic postconditioning is associated with down?regulation of DJ?1 expression in rats.

Objectives To investigate the relationship of methylenetetrahydrofolate reductase (MTHFR) and methioninesynthase reductase (MTRR) with unexplained recurrent spontaneous abortion (URSA). Methods Case control study was used to select 244 patients with URSA (miscarriage group) and 116 normal women (control group) who were admitted to Tianjin Medical University General Hospital and Tianjin Women’s and Children’s Health Center from January 2013 to March 2015. The oral mucosal epithelial cells were extracted using fluorescence quantitative PCR to detect MTHFR gene C677T, A1298C and MTRR gene loci of A66G single nucleotide polymorphisms (SNP). The relationship between folate metabolism related gene polymorphisms of MTHFR and MTRR and URSA was analysed. Results The frequency of C677T genotype MTHFR was significantly higher in URSA group than that in the control group, and the frequency of CT genotype was significantly lower than that of the control group (P<0.05). There was no significant difference in the frequencies of A1298C MTRR and A66G MTHFR between the two groups. The activity of MTHFR, red cell folate and plasma folate levels were significantly lower in URSA group than those of control group. Homocysteine levels were significantly higher in URSA group than those of control group (P<0.05). There were no significant differences in serum folic acid, red cell folate, homocysteine cysteine levels between patients <35 years old and ≥ 35 years old in URSA group. Conclusion C677TMTHFR gene polymorphism is associated with unexplained recurrent spontaneous abortion.

Objective To investigate the effects of penehyclidine hydrochloride on activities of nuclear factor kappa B (NF-kB) and activator protein-1 (AP-1) during actue lung injury induced by blunt chest trauma-hemorrhagic shock and resuscitation (HSR) in rats.Methods Thirty male Sprague-Dawley rats,aged 8 weeks,weighing 250-300 g,were randomly assigned into 3 equal groups (n =10 each) using a random number table:sham operation group (group S),blunt chest trauma-HSR group (group THSR) and penehyclidine hydrochloride group (group PHCD).The model of actue lung injury induced by blunt chest trauma-HSR was induced by dropping a 300 g weight onto a precordium in anesthetized rats.Blood was withdrawn via the femoral artery 5 min later until MAP was decreased to 35-45 mmHg within 15 min and maintained at this level for 60 min,followed by resuscitation.In PHCD group,PHCD 2 mg/kg was injected intravenously at 60 min after hemorrhagic shock.At 6 h after the model was established,blood samples were obtained for measurement of concentrations of tumor necrosis factor-alpha (TNF-α) in serum.The lungs were then removed for determination of lung water content,myeloperoxidase (MPO) activaty (by colorimetric assay),NF-κB and AP-1 activaties (using electrophoretic mobility shift assay) in lung tissues,and for microscopic examination of pathologic changes (under light microscope).The left lung was lavaged,and lung permeability index (LPI) was calculated.Results Compared with S group,lung water content,LPI,serum TNF-α level and activites of MPO,NF-κB and AP-1 were significantly increased in THSR and PHCD groups.Compared with THSR group,lung water content,LPI,serum TNF-α concentrations and activites of MPO,NF-κB and AP-1 were significantly decreased in PHCD group.The pathological damage to lung tissues was significantly reduced in PHCD group as compared with THSR group.Conclusion PHCD can inhibit activities of NF-κB and AP-1 in lung tissues,thus mitigating acute lung injury induced by blunt chest trauma-HSR in rats.

Objective To discuss the influent factors and managements of lower urinary tract injury caused by tension-free vaginal tape (TVT) procedure. Methods From Mar.2001 to Feb.2011,609stress urinary incontinence (SUI) patients were trested by TVT.Lower urinary tract injury appeared in 39 cases (6.4％),which age from 39 to 78 years (average age 52.7 ± 18.3).The history of disease was 2 to 12 years.Preoperative SUI types were 12 cases of Ⅱ type SUI,22 cases of Ⅱ/Ⅲ type SUI and 5 cases of Ⅲ type SUI.The patients who had low urinary tract injury were retrospective analyzed to figure out the causes and influent factors,and recorded the treatments and follow-ups. Results 39 patients (6.4％) suffered from low urinary tract injury,including 36 oases (5.9％) of bladder perforation and 3 cases of urethral injury.In these 39 patients,34 (87.2％) patients had history of pelvic surgeries,including 18 (52.9％) cases of total hysterectomy,9 (26.5％) cases of cesarean section delivery,4 (11.8％) cases of hysteromyomectomia and 3 (8.8％) cases of ovarian surgery.All of the 36 bladder peeroration patients were re-punctured and the catheter was kept for 4 - 5 d.Three urethral injury patients were re-punctured after the urethral rupture was sutured and the catheter was kept for 2 weeks.All the 39 patients were cured and discharged.No urinary fistula,infection or other postoperative complications occurred. Conclusions The history of pelvic surgery may be an important risk factor of the lower urinary tract injury,which should pay attention.If the bladder perforation occurred,re-puncture should be taken by adjust the direction.If there was a urethral injury,the re-puncture should be taken after the suturing of the urethral rupture.

Objective To investigate the effects of penehyclldine hydrochloride postconditioning on hind limb ischemia-reperfusion (I/R) injury in rats. Methods One hundred and forty-four male Wistar rats weighing 220-250 g were randomly divided into 4 groups (n = 36 each): control group (group C), I/R group, ischemic postconditioning group (group IPO) and penehyclidine hydrochloride postconditioning group (group PHPO). Limb ischemia was induced by occlusion of bilateral hind limb for 3 h followed by 24 h reperfusion. In group IPO, the animals were subjected to three cycles of 30 s reperfusion and 30 s ischemia on the proximal part of the hind limb,while in group PHPO, the animals received iv injection of penehyclidine hydrochloride 0.15 mg/kg (in normal saline 1 wl) via the caudal vein immediately after reperfusion. Blood samples from the inferior vena cava were taken for determination of activities of serum LDH and CK and concentrations of TNF-α and IL-10 at O, 1, 3, 6, 12 and 24 h of reperfusion. Then 6 rats were sacrificed at each time point respectively and the quadriceps femoris tissues of the hind limb were removed for determination of MDA content, activities of SOD, MPO, Na+ -K+-ATPase and Ca2 + - Mg2+ -ATPase, and HIF- 1 α expression and microscropic examination. Results Compared with group C, the activities of serum LDH and CK and concentrations of TNF-α and IL-10 were significantly increased, the activities of SOD, Na+-K+-ATPase and Ca2+-Mg2+-ATPase were decreased, MPO activities and MDA content were increased, HIF-1α expression was up-regulated in group I/R, IPO and PHPO (P ＜0.05 or 0.01). Compared with group I/R, the serum activities of serum LDH and CK and TNF-α concentration were significantly decreased, IL- 10concentration was increased, activities of SOD, Na+ -K+ -ATPase and Ca2+ -Mg2+ -ATPase were increased, and MPO activity and MDA content were decreased, HIF-1α expression was down-regulated (P ＜ 0.01), and the pathologic changes was reduced in group IPO and PHPO. Compared with group IPO, the serum LDH activity and TNF-α concentration were significantly decreased, CK activity and IL-10 concentration were increased, activities of SOD and MPO and MDA content were decreased and HIF-1α expression was down-regulated (P ＜ 0.05 or 0.01).Conclusion Penehyclidine hydrochloride postconditioning can reduce hind limb I/R injury in rats, and the mechanism is related to inhibiting inflammatory response and lipid peroxidation, reducing calcium overload and improving cellular energy metabolism.
