Objective To analyze the effects of puerperium pelvic floor muscle training on pelvic floor muscle strength and its clinical significance. Methods One hundred postpartum women were included, with full-term singleton pregnancies and with complete follow-up records from Obstetrics Department of Peking University First Hospital between March 1, 2013 and October 31, 2013. Women with vaginal birth and cesarean birth commenced pelvic floor muscle training twice a day from 24 and 72 h after delivery, respectively. According to the different training frequencies, the subjects were divided into three groups: never-training group, occasional-training group (<6 times per week) and regular-training group (≥6 times per week). All patients received pelvic floor muscle strength measurement 6-8 weeks after parturition. And the strength of type Ⅰ and type Ⅱ pelvic floor muscle fiber was divided into 0, Ⅰ, Ⅱ, Ⅲ, Ⅳ and Ⅴgrade. The abnormal strength of typeⅠand typeⅡpelvic floor muscle fiber standed for the grades lower thanⅢ. We compared the general conditions, delivery modes and abnormal ratio of type Ⅰ and type Ⅱ pelvic floor muscle fiber among the three groups, analyzed the relativity between the level of pelvic floor muscle fiber strength and pelvic floor muscle training frequency, and analyzed the influential factors of pelvic floor muscle fiber strength. Statistical analyses were performed by one-way ANOVA, rank-sum test, Pearson χ2 test, Kruskal-Wallis nonparametric test, Nemenyi test, Spearman rank correlation analysis and multivariate Logistic regression analysis. Results There was no statistical difference in age, gestation at delivery, parity, body mass index before delivery, neonatal birth weight and delivery mode among the never-training group (21 cases), occasional-training group (30 cases) and regular-training group (49 cases) (all P > 0.05). There was no statistical difference in labor time of first, second and total stage and episiotomy rate among the vaginal birth cases of the three groups. The abnormal ratio of type Ⅰ muscle fiber strength among the three groups was 100% (21/21), 77% (23/30) and 6% (3/49), respectively, while that of type Ⅱ muscle fiber strength was 100% (21/21), 53% (16/30) and 20% (10/49), respectively. And there were significant statistical differences among the three groups (F=119.16 and 77.84, both P<0.01). Spearman rank correlation analysis indicated that the level of typeⅠand typeⅡmuscle fiber strength had a significant positive correlation with pelvic floor muscle training frequency (r=0.88 and 0.79, both P<0.01). Multivariate Logistic regression analysis showed that pelvic floor muscle training was an influential factor for pelvic floor muscle strength level (95%CI:0.000-0.193, P<0.01). Conclusions Puerperium pelvic floor muscle training can help enhance the tension force of pelvic floor muscle, might benefiting the postpartum recovery of pelvic floor muscle function.

AIM: To study the effects of insulin and glucose on tissue-type plamingen activator (tPA) and its inhibitor-1 (PAI-1) secretion in cultured human endothelial cells. METHODS: Human endothelial cell line ECV-304 was cultured with glucose and/or insulin at different concentrations with or without hypoxic exposure. RESULTS: The tPA, PAI-1 secretion and ratio of tPA/PAI-1 increased in endothelial cells during hypoxia. Insulin and glucose increased the tPA and PAI-1 secretion in endothelial cells exposed to hypoxia, and increase in tPA/PAI-1 ratio was also observed at 4 h and 8 h. CONCLUSION: Hypoxia stimulates the release of tPA and PAI-1. Insulin and glucose also stimulate the tPA and PAI-1 secretion during hypoxia.

BACKGROUND: In the central nervous system(CNS) of normal adults there are neural stem cells or neural progenitor cells, which are capable of self-renewing and multiple differentiating. In normal physiological conditions, intrinsic neural stem cells are in a resting state. What state will they be in during cerebral ischemia?OBJECTIVE: To observe the distribution, proliferation and differentiation of intrinsic neural stem cells in focal transient ischemia in rats.DESIGN: A randomized controlled exploratory trial based on the rats.SETTING: Neurobiological department, histological and embryological department of a medical college.MATERIALS: The experiment was conducted in the Neurobiological Department of Luzhou Medical College from July 2001 to July 2002. Altogether 41 healthy adult SD rats of either gender, weighting 250 g - 300 g, were selected.INTERVENTIONS: The focal ischemia model was made by blocking middle cerebral artery(MCA) and reperfusing for 0.5 hour, 3 hours, 6 hours, 12 hours, 1 day, 2 days, 3 days, 5 days and 10 days. Sham-operation group was treated by the same method, but the filament was not long enough to block MCA, and normal rats served as control group. The rats were sacrificed at given time points, and their brains were made into cerebral slices. The single-and double-labeled immunohistochemical staining was employed to detect the proliferation, distribution and differentiation of intrinsic neural stem cells.MAIN OUTCOME MEASURES: The distribution, proliferation and differentiation of intrinsic neural stem cells.RESULTS: Immunoreactivity of proliferating cell nuclear antigen(PCNA)was present in most ependymal cells in ventricular zone(VZ), and PCNA-positive cells were sparsely distributed in the parenchyma in normal and sham-operation groups. At 3 hours of reperfusion, PCNA-labeled cells were first detected in rostral subventricular zone. At 12 hours of reperfusion and onward, PCNA-positive cells appeared in some choroid plexus cells in bilateral lateral VZ. At day 3 to day 10 of reperfusion, PCNA-labeled cells significantly increased in infarct boundary in preoptic area, striatum and deep layer of frontoparietal cortex. PCNA-labeled cells were first detected in subgranular zone of dentate gyrus 3 days after reperfusion, and increased with time. A very small number of double-positive cells expressed with PCNA and glial fibrillary acidic protein(GFAP) were first detected in infract boundary in preoptic area on day 3 and onward. No double-PCNA and NF-positive cells were detected within 10 days of reperfusion.CONCLUSION: Focal cerebral ischemia activates intrinsic neural stem cells, which proliferate and differentiate, and migrate toward ischemic striatum and frontoparietal cortex. This may help clarify the mechanism of functional recovery after ischemia.

BACKGROUND: There is few studies addressing the long-playing dynamic observation of cysteinyl aspartate specific protease 3 (Caspase-3) expression following cerebral ischemia/reperfusion.OBJECTIVE: To investigate the effect of transplantation of the neural stem cells (NSCs) modified with gene of glial cell line-derived neurotrophic factor (GDNF) on expression of Caspase-3 in adult Sprague Dawley rats with transient cerebral ischemia.DESING: Randomized controlled animal study.MATERIALS: Sixty Sprague Dawley rats were divided randomly into normal control group (N, n =5), ischemia/reperfusion group (IR, n=5), neural stem cell group (NSCs, n=25) and NSCs modified with gene of GDNF group (GDNF/NSCs, n =25). Several clean neonatal Sprague-Dawley rats were selected to harvest NSCs.METHODS: With the exception of normal control group, models of transient cerebral ischemia were created by modified suture method in other groups. At day 3 following reperfusion, 20 μL NSC suspension containing (4.0-5.0)×10~5 NSCs was infused into rats of the NSC group via right lateral ventricle. An equal volume of GDNF-modified NSC suspension was injected into rats of the GDNF/NSC group. 20 μL saline was infused into the rats of the ischemia/reperfusion group. Animals were anesthetized and sacrificed at week 1 following ischemia/reperfusion in the normal control and ischemia/reperfusion groups. Animals were anesthetized and sacrificed at weeks 1, 2, 3, 5, 7 following ischemia/reperfusion in the NSC and GDNF/NSC groups, 5 rats in each time point.MAIN OUTCOME MEASURES: The strept avidin-biotin immunostaining method was used to observe the distributive characteristics of Caspase-3 in the hippocampus and frontal parietal cortex.RESULTS: Immunohistochemical method (SP) showed that positive capase-3 products expressed in nucleus, cytoplasm and partial neurite. In hippocampus, number of Caspase-3-positive cells was decreased in NSC and GDNF/NSC groups. With the exception of at 1-week reperfusion, number of Caspase-3-positive cells was significantly lessened in the GDNF/NSC group compared with the NSC group at other time points (P < 0.05). In frontoparietal cortex, number of Caspase-3-positive cells was reduced in the NSC and GDNF/NSC groups over time. Except 1 and 2 weeks following ischemia/reperfusion, number of Caspase-3-positive cells was significantly lessened in the GDNF/NSC group compared with the NSC group (P < 0.05).CONCLUSION: Transplanting NSCs modified with gene of GDNF can improve remarkably neural function by deceasing Caspase-3 expression and reducing the nervous cell apoptosis. The transplantation of NSCs modified with gene of GDNF obtained better outcomes compared with NSC transplantation.
