p73 has high homology with the classical tumor suppressor gene p53. When overexpressed, p73 could lead to tumor cells growth arrest and induce apoptosis. Lost of p73 gene expression due to hypermethylation was found in about one third patients with acute lymphoblastic leukemia and Burkitt's lymphoma, but the expression level of p73 was higher in patients with acute myelogenous leukemia than that in normal white blood cells. Further research will be necessary to find out the role of p73 in leukemogensis.

Objective To compare and quantify the determinants in quantitative electroencephalogram(q-EEG) and heart rate variability power spectrum analysis(HRV-PSA) of ketamme(KTM) anesthesia for preschoolers.

Objective To analyze the trend of maternal mortality ratio (MMR) and cause of death in Shanghai from 1996 to 2015.Methods To collect the material about the maternal death and the maternal death audit from 1996 to 2015,and to analyze the MMR,the cause of death and the result of the maternal death audit of Shanghai from 1996 to 2015 retrospectively.Results (1) The change of MMR:the MMR in Shanghai decreased from 28.84 per 100000 live births in 1996 to 6.66 per 100000 live births in 2015.(2) The characteristic of maternal death:the proportion of Shanghai citizens was 27.4％(121/441) and the proportion of migrant women was 72.6％(320/441).The women with advanced maternal age was 8.2％(20/243) since 1996 to 2005,and increased to 16.7％ (33/198) since 2006 to 2015.Maternal deaths during pregnancy increased from 27.6％(67/243) in the first 10 years (1996-2005) to 35.4％(70/198) in the recent 10 years(2006-2015).The intrapartum maternal deaths was 6.2％(15/243) in the first 10 years and in the recent 10 years it was zero.The proportion of postpartum deaths in the first 10 years and in the recent 10 years were 66.3％ (161/243) and 64.6％(128/198) respectively.(3) The cause of maternal death:During the recent 10 years,indirect obstetric causes [63.1％(125/198)] was more than direct obstetric causes [36.9％(73/198)] for the first time.The death causes changed significantly.Postpartum hemorrhage remained the leading cause of maternal deaths,but the specific mortality rate (SMR) of postpartum hemorrhage decreased significantly from 7.42 per 100000 live births in the first 10 years to 1.51 per 100000 live births in the recent 10 years.The maternal deaths because of heart disease and cerebrovascular disease rose to the second and the forth reasons.(4) Maternal death audit:the avoidable maternal death ratio decreased from 3.66 per 100000 live births in the first 10 years to 1.86 per 100 000 live births in the recent 10 years.Conclusions During the past 20 years,the MMR of Shanghai decreased significantly and was close to the level of developed countries.In recent years,the causes of maternal death become more complicated.With the implementation of the second child policy,women with high risk factors increase,so government investment,policy support should be strengthened to optimize the management.

Objective To investigate the effect of hydrogen sulfide(H2S)on gene expression of adenosine triphosphate(ATP)-sensitive K+ channel(KATP)of aortic smooth muscle cells(ASMC)in rat.Methods Male Sprague-Dawley(SD)rats were used in the study.The original generation cells were obtained by modified tissue piece inoculation.The passaged cells were used.The ASMC were divided into 2 groups:H2S group of different dosages and control group.The contents of sodium hydrosulfide in the culture media of H2S group were 10-5,10-4 and 10-3 mol/L respectively,and the same volume of normal saline was added to control group.Each group was treated for 24 hours.Morphology of the cells was observed by inverted microscope and identified by immunohistochemical method employing ?-smooth muscle-actin.The expressions of SUR2B and Kir6.1 were identified by immunohistochemical SP technology.The SUR2B mRNA and Kir6.1 mRNA levels were assayed by real time fluorescence relative quantitative polymerase chain reaction.Results The passaged cells developed typical growth pattern peak and valley and the 97th percent of the cells expressed the smooth muscle specific differentiation marker ?-smooth muscle-actin.SUR2B and Kir6.1 could be detected in ASMC by immunohistochemical technology.They were both located at cytoplasmic and cytomembrane but not in at nucleus.Compared with control group,SUR2B mRNA and Kir6.1 mRNA levels in H2S groups were higher than those in control group in a dosage-dependent mode.Conclusions H2S can increased the expression KATP channel SUR2B mRNA and Kir6.1 mRNA levels of ASMC.J Appl Clin Pediatr,2009,24(1):21-23

This paper is in order to discussion with the composition and characteristics of Tibetan medicine plant resources, and promote the reasonable protection and utilization of the resources of Tibetan materia medica. Statistical analysis of species, distributions, and others of Chinese endemic seed plant from Tibetan medicine plants and usually used in the clinic of Tibetan medicine. The results showed that there are 523 species (25%) of Chinese endemic seed plant, belonging to 65 families and 162 genera, in about 2 000 varieties of Tibetan medicine plants recorded in relevant literatures. There are 180 Chinese endemic seed plant species (28%) belonging to 42 families and 72 genera from 625 medicine plants usually used in the clinic of Tibetan medicine. Specifically, the most of these Chinese endemic seed plant species are characteristic crude drug used in Tibetan medicine, and mainly or only distributed in Qinghai-Tibet Plateau. And a few species of them were intersected with traditional Chinese medicines (TCM) and other ethnic medicines. In addition, about 10% are listed in China Species Red List. The Qinghai-Tibet Plateau is the most abundant areas of Areal-types of the Chinese endemic seed plant. This is the biological and ecological reason formation the characteristics of Tibetan medicine plant resources. Therefore, strengthen the research of Chinese endemic seed plants used in Tibetan medicine is great significance for the reasonable protection and utilization of Tibetan medicine plant resources.

Objective: To investigate the status of knowledge about acquired immune deficiency syndrome(AIDS) among college freshmen in Jiangsu Province, and to analyze the influences of AIDS-related knowledge on their sexual attitudes and behaviors. Methods: A total of 8 633 freshmen from 20 colleges and universities in Jiangsu Province were enrolled by multi-stage stratified sampling. The questionnaire for young students about the eight items of AIDS basic knowledge were used to investigate the AIDS-related knowledge, sexual attitudes and behaviors. Multivariate Logistic regression model was used to analyze the influencing factors of the AIDS-related knowledge and to adjust the influences of AIDS-related knowledge on sexual attitudes and behaviors. Results: The overall qualified rate of AIDS-related knowledge among college freshmen in Jiangsu Province was 87.6% and the qualified rate of 8 items were between 59.8% and 98.3%. The types of schools, nationality, mother s education level and whether only child or not were identified as independent factors for qualified rate of AIDS-related knowledge(P<0.05). The awareness of AIDS-related knowledge had significant impacts on the sexual attitudes and behaviors of college freshmen. Students with insufficient knowledge were more likely to approve premarital sexual behaviors(OR=1.31, 95%CI=1.11-1.63), willing to use condoms consistently(OR=1.67, 95%CI=1.43-1.92) and to accept the HIV tests(OR=4.54, 95%CI=3.13-6.52). Students with unqualified knowledge were more likely to have sexual behavior(OR=1.89, 95%CI=1.42-2.49), while those with sexual experiences and insufficient AIDS knowledge were more likely to use condoms consistently(OR=2.13, 95%CI=1.22-3.78). Conclusion The education on AIDS-related knowledge for teenagers was helpful to construct correct sexual concepts and develop healthy sexual behaviors. However, the AIDS-related knowledge of college freshmen in Jiangsu Province is not sufficient and needed to improve.

OBJECTIVE: In order to understand which kind of function genes play an important role for estimating wound age, the variation of difference genes' mRNA expression were compared after injury. METHODS: The mRNA expression levels of seven candidate genes (ICAM-1, NF-κB, MX2, MT1, MT2, sTnI, and Cox6c) were analyzed in contused rat skeletal muscle at different time points using real-time fluorescent quantitative PCR (RT-qPCR). The raw Ct values were normalized relative to that of RPL32 mRNA, and converted to standard Ct values. At each time point after injury, the standard deviations (SD) of the standard Ct values were calculated by SPSS. RESULTS: The expression trends of the seven genes were all found to be related to wound age, but there were lower variation coefficients and greater reliability of s TnI and Cox6c when compared with other genes. CONCLUSION The genes encoding structural proteins or proteins that perform basic functions can be suitable for wound age estimation.
