Glomerular hypertrophy is the main pathological characteristic in the early stage of diabetic nephropathy (DN), and its regulatory mechanism is closely related to mammalian target of rapamycin (mTOR) signaling pathway activity. mTOR includes mTOR complex 1 (mTORC1) and mTOR complex 2(mTORC2), in which, the upstream pathway of mTORC1 is phosphatidylinositol-3-kinase (PI3K)/serine-threonine kinase(Akt)/adenosine monophosphate activated protein kinase(AMPK), and the representative signaling molecules in the downstream pathway of mTORC1 are 4E-binding proteins(4EBP) and phosphoprotein 70 S6Kinase(p70S6K). Some Chinese herbal extracts could improve cell proliferation via intervening the expressions of the key molecules in the upstream or downstream of PIK/Akt/mTOR signaling pathway in vivo. As for glomerular mesangial cells(MC) and podocyte, mTOR plays an important role in regulating glomerular inherent cells, including adjusting cell cycle, energy metabolism and matrix protein synthesis. Rapamycin, the inhibitor of mTOR, could suppress glomerular inherent cell hypertrophy, cell proliferation, glomerular basement membrane (GBM) thickening and mesangial matrix deposition in model rats with DN. Some Chinese herbal extracts could alleviate glomerular lesions by intervening mTOR signaling pathway activity in renal tissue of DN animal models or in renal inherent cells in vivo and in vitro.

OBJECTIVETo analyze the maternal mortality ratio (MMR) of residential and migrant women in Beijing.
METHODSA retrospective study from 1995 to 2004 was performed to analyze data from the maternal death cases.
RESULTSThe MMR of resident and migrant of Beijing from 1995 to 2004 were 17.9 and 51.3 per ten thousand respectively. The main reasons of maternal deaths among residents were embolism (21.2%), hypertensive disorder complicating pregnancy (18.3%), postpartum hemorrhage (14.4%) and ectopic pregnancy/heart disease (9.6%). The main reasons of migrant maternal deaths were postpartum hemorrhage (25.2%), embolism (19.7%), hypertensive disorder complicating pregnancy (17.3%) and liver disease (9.5%). The avoidable deaths were accounted for 18.9%.
CONCLUSIONThe MMR in Beijing local residents was close to that in developed countries. To further reduce MMR in Beijing would depend on the better administration of related issues among floating population. Poor quatily delivery must be banned together with strengthening the training programs on health workers. It is also important to improve the knowledge and skills of medical staff for rescuing the complications of pregnancy and ectopic pregnancy.

This study was aimed to investigate the effects of xenogeneic antigen neu-Fc in combination with the recombinant human granulocyte-macrophage colony stimulating factor (GM-CSF) and Bacillus Calmette-Guerin (BCG) on the regulation of Th1 and Th2 immune response in vitro. The rat neu L2-S2 domain was engineered as a chimeric protein with human IgG Fc. The eukaryotic expression vector was constructed. The recombinant protein was stably expressed in CHO cells and purified by rProtein A Sepharose Fast Flow column. The recombinant protein was identified by SDS-PAGE and Western blot. Peripheral blood mononuclear cells (PBMNCs) were obtained by means of standard Ficoll separation from the blood of healthy donors. Neu-Fc-induced PBMNC proliferation was tested by MTT. The production of IL-12 and IL-10 was measured by ELISA. The results showed that the level of IL-12 decreased and IL-10 increased after PBMNCs were incubated with MCF-7 cultural supernatant. 10 nmol/L neu-Fc strongly induced the cell proliferation. Compared with neu-Fc or GM-CSF or BCG treatment alone, neu-Fc in combination with GM-CSF and BCG significantly stimulated IL-12 production and inhibited IL-10 production (p < 0.01). It is concluded that the neu-Fc can stimulate the proliferation activity of PBMNCs. neu-Fc, GM-CSF and BCG costimulation efficiently induces Th1 immune response.

OBJECTIVETo analysis the trend of maternal death time and explore the impact of the variety of death causes and birth place to maternal death time.
METHODSAccording to the data provided by Beijing Maternal and Children Health Hospital, the 372 death cases of pregnant and lying-in women from 1995 to 2010, a retrospective study was performed to analyze the death causes, maternal death time and the influencing factors.
RESULTSThe MMR declined from 27.9 per 100 000 live births from 1995 to 2000 to 14.8 per 100 000 live births from 2006 to 2010, with a decline of 46.9%. Among the maternal death within 24 hours of delivery, 79.7% (106/133) died of obstetric hemorrhage, hypertensive disorder complicating pregnancy and amniotic fluid embolism. It took up 47.8% (64/134) from 1995 to 2000, reduced to 37.5% (45/120) from 2006 to 2010. At the same time, the maternal mortality ratio within 24 hours reduced from 40.2%(54/134) to 28.3% (34/120), the variation of death time was consistent with the causes of maternal mortality (χ² = 59.109, P < 0.05). Indirect obstetric causes increased significantly from 2006 to 2010, 53.2% (33/62) of pregnant women with heart disease, cerebrovascular disease and pulmonary embolism died in prenatal or more than 120 hours postnatal. Among the maternal death delved in hospital, 29.0% (29/100) died within 24 hours, 52 cases delved at home or in private clinics, 43 cases (82.6%) died within 24 h postnatal. There were significant differences between birth place and death time (χ² = 24.500, P < 0.05).
CONCLUSIONMaternal death time changed from 24 hours of delivery to prenatal or postnatal a long time. The maternal mortality causes and hospital delivery is an important factor affecting maternal time.

Objective To provide evidence for further reducing the maternal mortality rate (MMR) through analyzing the causes of death and influencing factors on the issue.Methods Every maternal death from 1996 to 2010 was audited by experts and relevant information was collected and analyzed,retrospectively.Results (1) The overall MMR among Beijing residents was 20.2 per 100 000 live births in 1996-2000 while decreased to 14.2 per 100 000 live births from 2006 to 2010.At the same time,the MMR of migrating people decreased from 47.7 to 15.2 per 100 000 live births.(2) The proportion of women having received middle school education and above,increased from 59.8% to 78.8% and the non-prenatal care maternal ratio decreased from 39.1% to 12.7%.(3) Among the 349 deaths in the period of 1996-2010,209 (59.9%) were caused by direct obstetric reasons.Proportion of obstetric hemorrhage declined from 14.4% to 9.2% and the amniotic fluid embolism declined from 20.7% to 15.0%.Prolific,non-prenatal care and private clinics/home deliveries were important factors on direct obstetric reasons.71.4% maternal mortality of indirect causes appeared abnormal during pregnancy.(4) The WHO twelve-grade classification standard on maternal deaths was adopted.Our data showed that the main reasons causing maternal deaths of Beijing residents were related to the skills of medical staffs (62.4%) and healthcare management (19.7%).The main reasons of maternal deaths among migrating people would include:poor knowledge (41.4%),inappropriate attitude(32.3%) and resources of the families(24.0%).Conclusion The MMR in Beijing continuously declined from 1996 to 2010.However,in order to keep up with the changing causes related to maternal deaths as well as to the increasing service requirements,it is necessary to develop a new model on service and management of the issue.
