Objective To investigate the possibility of reserving uterus during severe postpartum hemorrhage. MethodsA retrospective analysis was conducted on the clinical data of 138 cases of severe postpartum hemorrhage (blood loss ≥2000 ml) from January 1, 2003 to December 31, 2009. Results Among 138 cases of severe postpartum hemorrhage, uterine atony (n= 60, 43. 38 ％ ) was the first cause and the second was placental factor (n= 55, 39.86 ％). The blood loss varied from 2000 ml to 10 000 ml and the mean level was about (3004± 1473) ml. The volume of blood transfusion for these patients varied from 800 ml to 7200 ml. Among these patients, the blood loss of 108 cases reserved uteri was from 2000 ml to 7500 ml, with the average of (2564±932) ml； while for 30 cases performed with hysterectomy, the blood loss was about 2500 to 10 000 ml averagly (4653± 1857) ml (t=8. 57, P=0.00). These patients were divided into two groups according to time series. Twelve cases of hysterectomy were performed during 2003to 2005, and the hysterectomy rate was 0. 47‰; 18 cases of hysterectomy were performed during 2006 to 2009, and the hysterectomy rate was 0. 36‰. The average blood loss of the above two groups was (3783±861) ml and (5233±2124) ml respectively (t=2. 234, P=0. 034). Among all the cases with blood loss ≥ 3000 ml, uteri were reserved in 24 cases with the average blood loss of (3818 ± 1284) ml； while hysterectomy were performed in 27 cases with average blood loss of (4900 ± 1789) rnl (t = 2. 453, P =0. 018). The time for blood loss to 3000 ml in the two groups was (160±129) min and (100±67) min,respectively, and the difference was significant (t=2. 113, P = 0.04).The uteri of six cases with postpartum hemorrhage over 4000 ml were successfully reserved, and average bleeding amount was 5570 ml.Two patients among the 138 women died of amniotic fluid embolism.The perinatal mortality rate was 3. 73％.ConclusionsThe postpartum hemorrhage volume and velocity is the key point to decide whether to reserve the uterus or not.For the population with high risk factors,prophylaxis treatment with prostaglandins should be initiated to reduce the bleeding volume.Uterine packing might be an effective treatment to stop postpartum hemorrhage, especially for those bleeding due to placenta previa.

5-Fluorouracil(5-FU)has been widely used to treat gastrointestinal,head,neck,chest and ovarian malignant tu-mors since 1957. As an analogue of pyrimidine,5-FU plays anti-cancer roles by inhibiting thymioylate synthase and integrating its me-tabolites into DNA and RNA. Although 5-FU is one of the first-line therapeutic compounds for gastrointestinal malignant tumor as a sin-gle drug or in combination with other drugs,its effectiveness is hindered by its low efficiency,which may be due to chemotherapy re-sistance. 5-FU chemotherapy resistance may stem from enzyme abnormality,genetic abnormality and tumor microenvironment. In this paper,we make a review about 5-FU actions and the mechanisms underlying chemotherapy resistance.

Cranial irradiation is routinely used for the treatment of almost all brain tumors,but it may cause disastrous injury in brain,especially in the hippocampus that has cognitional and emotional regulation functions.Several studies have investigated the mechanisms of radiation-induced hippocampal dysfunctions such as hippocampal neurogenesis,neurotrophin and neuroinflammation,and provided effective prevention strategies such as exercise,environmental enrichment,anti-inflammatory and intrahippocampal transplantation of neural stem cells.This review discussed the curent progresses and challenges of hippocampal dysfunction induced by cranial irradiation and provided new insights for preclinical and clinical researches.

Through demonstrating the satisfaction evaluation system of Singapore hospitals,the article analyzed the differences between the satisfaction evaluation system of Singapore and the system made by Shanghai Municipal Commission of Health and Family Planning.It was concluded that the humanized evaluation methods should be highlighted,the conformity of establishment of evaluation system and policy be focused on,staff incentive mechanism be focused on and perfected,and patients' expectation indicator and perceived quality be considered as strategic tools to improve the healthcare system performance.

Epilepsy is one of the major clinical features of tuberous sclerosis complex, and it is drug-resistant in the majority of cases.Surgical resection is an effective way to resolve the seizures.Precise preoperative evaluation is critical to the surgical outcome.Preoperative evaluation mainly aims to determine the range of the epileptogenic zone and the functional areas that should be preserved.Because of the complexity of the epileptogenic mechanism and brain network, there isn′t a single and specific measure that can accurately position the epileptogenic zone, so it is necessary to comprehensively evaluate and localize the epileptogenic zone by using multiple methods, including collection of a detailed medical history, symptomatic analysis during the attack of seizures, magnetic resonance imaging, positronemission tomography, electroencephalogram, neuropsychological evaluation, etc.In this paper, the rational use of above-mentioned approaches and comprehensive analysis of their results were summarized, which play an essential role in contro-lling seizures in children with tuberous sclerosis complex and refractory seizures.

OBJECTIVE To investigate the status of nosocomial infection in community health services and offer a scientific basis for nosocomial infection control.METHODS Totally 5738 outpatients were investigated retrospectively for nosocomial infection in community.RESULTS The most frequently nosocomial infection sites were lower respiratory tract,and next upper respiratory tract and urinary tract(2131,1045 and 934,respectively).The major reasons of causing the nosocomial infection were irrational usage of antibacterial drugs(39.0%),invasive procedures(31.0%) and using glucocorticoids(10.0%).Most of the pathogenic bacteria of the nosocomial infection were Gram-negative and the next were Gram-positive and fungi.74.4% of the pathogens were resistant to most of antibioties.CONCLUSIONS Alzeimer′s disease patients in the community health centers are popular and susceptible to infection.

Objective To study the effects of Nerve Regeneration Factor on the neurite growth and Neurofilament-H expression of rat dorsal root ganglions in vitro. Methods DRG was cultured and treated with NRF,observation made by fluorescent immunocytochemistry and the mRNA and protein level of NF-H of DRG neurons was detected by real-time fluorescence quantitative RT-PCR and Western blot. Results NRF can promote the neurite growth of DRGs in vitro.The mRNA and protein levels of NF-H of DRG neurons can be up-regulated by NRF in a dose-dependent manner,with the best concentration of 2.0?(mg/L.) Conclusion\ NRF can promote the neurite growth of DRGs in vitro.NRF exerts a neurotrophic action on developmental sensory neurons.
