Brain injury is a significant cause leading to death of neonates with a considerable variety of complications.Up to now researches have found the neuroprotective actions of erythropoietin (EPO) originally identified as erythropoiesis on neonatal brain injury.EPO has been reported to induce a broad effect in the brain directed to protect and repair neurons damage which are likely to contribute to the improvement in long-term neurological functional outcomes.EPO may provide a new approach for promoting survival and growth in nerve cells and hold great promise for the future treatments of neonatal brain injury.EPO and EPO receptor distribute in defferent parts of brain in fetus and newborns.A fundamental mechanism of EPO-induced neuroprotection is its ability to inhibit apoptosis that EPO and EPO receptor have been shown to modulate three cellular signal transduction pathways.The other neuroprotection mechanisms of EPO-induced include anti-infammatory,neurotrophy,anti-oxidation,angiogenesis,promoting neurogenesis and anti-epilepsy.

Objective To investigate mRNA expression of matrix metalloproteinase (MMP-9) and tissue inhibitor of metalloproteinase (TIMP-1) in ectopic endometriosis tissue and uterine endometrium from women with and without endometriosis. Methods Thirty-eight women with endometriosis (Revised American Fertility Society classification, RAFSⅠ-Ⅳ) were selected as study group. Thirty-eight specimens of ovarian endometrioma(ovarian chocolate cysts, OCC), 16 red peritoneal endometriotic lesions(RPL), and 35 matched eutopic endometrium(Eu) were collected from them simultaneously at the time of surgery. Twenty specimens of endometrium from reproductive women undergoing laparoscopic surgery without endometriosis were obtained as control group. The mRNA expressions of MMP-9 and TIMP-1 were detected by reverse transcription polymerase chain reaction (RT-PCR). Results Expression of TIMP-1 mRNA was detected in all samples. The level from endometriosis patients and control group was similar(2.31?1.21, 2.40?0.89). However, ectopic endometrium expressed significantly fewer TIMP-1 mRNA(OCC 1.67?0.79, RPL 1.45?0.68)compared with eutopic endometrium from both endometriosis and endometriosis-free patients(P

Objective To investigate and compare the special psychologic characteristics of the post-traumatic epilepsy patients and their spouses.Methods The complete clinical data of 244 patients and their spouses were retrospectively and constractively analyzed. There were two distinct groups because of the etiology: group A including 122 patients of post-traumatic epilepsy and their spouses, and group B including essential epilepsy. Symptom Checklist-90 (SCL-90), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) were used to evaluate the psychologic status of objects.Results All of the single-item score of SCL-90 were significantly higher than the China norm (P<0.01) in both groups, and the score in group A was higher than that in group B. But the characteristics of the abnormal data were diffierent in patient from in spouse. The scores of the post-traumatic patients were higher than that of the spouses in 3 items, and lower in 5 items. Specially the depression and anxiety emotion of the spouses were more obvious than the patients in group A (P<0.01).Conclusion Both the patient and spouse have the conspicuous psychosomatic disorder, and the appearance is diffierent from each other. The psychosomatic disorder of post-traumatic epilepsy patient and spouse is more conspicuous than the essential epilepsy.

Objective To investigate the relationship of hypothyroxinemia to gestational diabetes mellitus during early pregnancy. Methods A total of 11 365 cases of women with early singleton pregnancies were collected from Chongqing Health Center for Women and Children. The screening of thyroid function was performed. The postload glucose concentrations and the risks of gestational diabetes mellitus in hypothyroxinemia were investigated. The relationship of thyroid hormones to postload glucose concentration was evaluated. The association between thyroid peroxidase antibodies(TPOAb) and gestational diabetes mellitus was analyzed. Results Early pregnancy women with hypothyroxinemia had a higher postload glucose concentration. Comparing to normal pregnancy women, the prevalence of gestational diabetes mellitus in hypothyroxinemia was higher(42.2%vs18.4%, P<0.05). Free thyroxine(FT4) was significantly negatively correlated with postload glucose concentration. FT4 was associated with gestational diabetes mellitus. The risk of gestational diabetes mellitus was greater when FT4 was lower. The prevalence of gestational diabetes mellitus in early pregnancy women with TPOAb levels ≥500 IU/ml was significantly higher than that in normal pregnancy women (31.2%vs 18.4%, P<0.05). Conclusion Early pregnancy women with hypothyroxinemia and TPOAb≥500 IU/ml were related to the risk of gestational diabetes mellitus. Lower FT4 was the risk factor of gestational diabetes mellitus.
