AIMTo explore the effect of ligustrazine injection on the expression of heme oxygenase-1 (HO-1) in rabbits with pulmonary ischemia/reperfusion injury after.
METHODSSingle lung ischemia/reperfusion injury animal model was used in vivo. Twenty rabbits were randomly divided into two groups( n = 10, in each), pulmonary ischemia/reperfusion injury (I/R) group and I/R + ligustrazine injection (LGT) group. The tissue slides were stained by immunohistochemistry (IHC) and in situ hybridization (ISH) for HO-1 to detect the expression of HO-1 in lung and to analyze the absorbance, wet to dry ratio of lung tissue weight (W/D) and the injured alveoli rate (IAR) were measured at 180 minutes after lung reperfusion. Meanwhile the lung tissue slide was prepared for electron microscopic observation at 180 minutes after reperfusion.
RESULTSHO-1 expression was upregulated in two groups in the pulmonary endothelial cells, part of pulmonary vascular smooth muscle cells, extima of vessels and epithelial cells of airway, the absorbance was 0.168 +/- 0.016 (0.148 +/- 0.013), 0.186 +/- 0.014 (0.158 +/- 0.012) respectively.The LGTI group showed higher absorbance than those of the I/R group (P < 0.01), lower W/D and IAR values than those of the I/R group (P < 0.01) significantly and lighter abnormal changes of the lung tissue in morphology than those of the I/R group.
CONCLUSIONLigustrazine injection possesses notable protective effects on I/R in rabbits by increasing the expression of HO-1 in lung.

OBJECTIVETo investigate the effects of cyclosporine A (CsA), a powerful inhibitor of mitochondrial permeability transition pore (MPTP), on pneumocyte apoptosis, the release of cytochrome C and the activity of caspase-3 after lung ischemia/reperfusion, and explore the mechanisms.
METHODSSingle lung in situ ischemia/reperfusion animal model was used. 30 SD rats were randomly divided into three groups (n = 10): sham (S) group, ischemia/reperfusion (I/R) group and cyclosporine A (CsA) group. Apoptosis of pneumocyte was assessed by TUNEL method, cytochrome C (CytC) in cytoplasm was detected by immunohistochemistry techniques, and the activity of caspase-3 was measured with spectrophotometer.
RESULTSThe content of CytC in cytoplasm, the activity of caspase-3, and the value of apoptosis index (AI) in ischemia/reperfusion group were evidently higher than that in S group (P < 0.01). CsA suppressed apoptosis as well as CytC release and caspase-3 activity (P < 0.01).
CONCLUSIONCsA can prevent the release of cytochrome C, block the apoptosis of pneumocyte accordingly maybe by closing the MPTP.

OBJECTIVETo explore the quality of the embryos, clinical outcomes and birth defects resulting from intracytoplasmic sperm injection (ICSI) treatment using sperms of different origins and parameters.
METHODSA total of 980 ICSI-ET (embryo-transfer) cycles were divided into 4 groups, namely normal sperm or mild oligozoospermia group (group A), severe oligozoospermia group (group B), epididymal aspirates group (group C) and testicular biopsies group (group D). The cleavage rate, embryo quality, fertilization rate, clinical pregnancy rate, and rates of birth defects were compared between the groups.
RESULTSThe fertilization rate, cleavage rate and good-quality embryo rate were not significantly different among the 4 groups (P>0.05), and the embryo implantation rate and clinical pregnancy rate were significantly higher in group C than in groups A and B (P<0.05). Groups A, B and C showed no significant differences in the rates of birth defects (P>0.05), and no birth defects occurred in group D.
CONCLUSIONSSperms of different parameters and origins used in ICSI treatment can achieve similar fertilization rate, good-quality embryo rate and delivery rate. The embryo implantation rate and clinical pregnancy rate of epididymal sperm group are higher than those of ejaculated groups, possibly due to the younger age of the patients and a greater number of oocytes retrieved in group C than in groups A and B.

OBJECTIVETo explore the effects of hepatitis B virus X gene and p53 on hepatocellular growth.
METHODSTwo kinds of plasmids containing sense and antisense human wild p53 gene respectively were constructed. SMMU-7721 cells were transfected with HBx, sense-wtp53 antisense-wtp53 separately or cotransfected with either HBx and sense-wtp53 or HBx and antisense-wtp53. Flow cytometry was adopted to measure the apoptosis rates and the effects of HBx on cell cycle progression. The activity of p21(Waf1) promoter-luciferase construct was detected. Growth curves for SMMU-7721 stably transfected with pcDNA3 and pcDNA3HBx were analyzed.
RESULTSAfter doxorubicin administration, HBx was noticed able to initiate apoptosis of the liver cells. The apoptosis rate was 5.32% in the pcDNA3 transfected and 12.66% in the pcDNA3HBx transfected groups respectively. HBx could also abrogate p53-mediated apoptosis. The apoptosis rate in groups transfected with pcDNA3, pcDNA3wtp53 and pcDNA3HBx + pcDNA3wtp53 was 5.32%, 11.72% and 4.67% respectively. In compared with the normal group, the number of cells in transiently HBx-expressed group and HBx-transfected group decreased 4.79% and 10.25% respectively. HBx inhibited the activity of p21(Waf1) promoter-luciferase constructed (P < 0.05) and promoted cell growth. The growth rate of HBx expression cells was faster.
CONCLUSIONUnder DNA damage, HBx reduced expression of p21(Waf1) by repressing the activity of p53 protein, followed by disturbing the regulation of G(0)-G(1) cell cycle checkpoint, and promoted the growth rate of hepatoma cells.

OBJECTIVETo investigate whether gender is an independent predictor of in-hospital death in hospitalized patients with acute myocardial infarction (AMI).
METHODSThis retrospective study compared baseline characteristics, therapeutic approaches and the occurrence rate of angina pectoris, reinfarction, heart failure and death during hospitalization between 1501 male and 635 female hospitalized patients with AMI. Multivariate logistic regression analysis was performed to identify risk factors predicting in-hospital death.
RESULTSIn-hospital death rate was significantly higher in female than male patients with AMI (11.7% vs. 6.3%, P < 0.01). Female patients with AMI were significantly older than male patients [(67.8 +/- 9.2) years vs. (61.1 +/- 11.9) years, P < 0.01] had a higher incidence of hypertension (52.1% vs. 41.1%, P < 0.01), diabetes mellitus (35.4% vs. 17.3%, P < 0.01), cardiac function > or = Killip class III (11.7% vs. 5.1%, P < 0.01) and TC > 4.68 mmol/L (71.3% vs. 55.0%, P < 0.01). Cigarette smoking, however, was more common in males than in females (69.4% vs. 15.7%, P < 0.01). Reperfusion therapy within the first 24 hours after symptom onset, beta-blockers and statins use during hospitalization were significantly fewer in females compared with males (22.2% vs. 31.5%, P < 0.01; 64.6% vs. 71.2%, P = 0.003; 43.1% vs. 48.0%, P = 0.041, respectively). An increased mortality was demonstrated in females during the hospitalization phase of AMI (11.7% vs. 6.3%, P < 0.01). The results of logistic regression demonstrated that age, diabetes mellitus, hypertension, Killip classification of cardiac function, administration of reperfusion therapy and beta receptor blockers use were significant predictors of in-hospital death in patients with AMI, with odds ratios being 1.06 (95% CI: 1.04 - 1.08), 1.96 (95% CI: 1.32 - 2.90), 1.80 (95% CI: 1.25 - 2.58), 2.86 (95% CI: 2.35 - 3.48), 0.44 (95% CI: 0.30 - 0.66) and 0.51 (95% CI: 0.36 - 0.74), respectively.
CONCLUSIONSThe in-hospital mortality of females is significantly higher than that of males in this patient cohort. Older age, higher risk factor rates, less reperfusion therapy and beta-blockers use contributed to the higher in-hospital mortality in female patients with AMI compared to males.

OBJECTIVETo investigate the association of the clinical characteristics and the outcome of in vitro fertilization and embryo transfer (IVF-ET) in infertile women with polycystic ovarian syndrome (PCOS) of different subtypes.
METHODSA total of 189 infertile women with PCOS undergoing IVF-ET were enrolled in this study. According to Rotterdam PCOS diagnosis criteria, the patients were classified into 3 PCOS subtypes, namely type I with PCO ultrasonography and oligo-ovulation/anovulation and hyperandrogenism (54 women, for whom 58 fresh IVF-ET cycles were performed); type II with PCO ultrasonography and oligo-ovulation/anovulation (117 women with 126 cycles); type III with PCO ultrasonography and hyperandrogenism (18 women with 18 cycles). The number of retrieved oocytes, fertilization rate, implantation rate, clinical pregnancy rate, spontaneous abortion rates and incidence of ovarian hyperstimulation syndrome (OHSS) were compared between the 3 groups.
RESULTSExcept for the baseline serum T concentration in the early phase of menstrual cycle, which was significantly higher in groups I and III than in group II, no significant difference was found in the clinical characteristics between the 3 groups (P>0.05). Group I had the highest initial Gn dose, and the oocyte retrieval rates were significantly lower in groups I and III (P<0.05). The patients in group I had lower implantation rate and the clinical, on-going and cumulative pregnancy rates than groups II and III, but the differences were not statistically significant; the embryo early loss rate and spontaneous abortion rate appeared to be higher in groups I and III (P>0.05). Significantly elevated incidence of OHSS were noted in groups I and III (P<0.05).
CONCLUSIONThe women with different PCOS subtypes according to the Rotterdam criteria all have similar IVF-ET outcomes, and the increased embryo loss rate and spontaneous abortion rate in groups I and III might be associated with excessive androgen that disturbs oocyte and embryo development.
