Nursing experience in the therapy of 45 cases of Rh blood group incompatibility was reported,and the nursing requirements were raised as follows:(1)good nurse patients relationship is important and psychological nursing should be done well.(2)Teach the patient to insist of systematic treatment,master timely intrauterine state of fetus.(3)Observe progressions and regression of jaundice,and general statement of newborn.(4)Enhance newborn nursing in the phototherapy.(5)Observe newborns physical signs in the course of blood exchange,predict the occurrence of complications.Results:one case was labor induced sine fetal death,40 cases lived without complications,4 cases died,the cure rate reached 88.9 percent.Conclusion:Though Rh blood group incompatibility is severe,most of them can be cured through timely treatment and careful nursing.

Objective To study telomerase activity in cervical cancer and it′s precursor lesion Methods Thirty six cervical cancer and 16 cervical intraepithelial neoplasia (CIN) specimens were measured for telomerase activity using TRAP ELISA, and 11 normal cervix, 6 chronic cervicitis and 8 adjacent normal tissue specimens as controls Results Mean telomerase activity in CIN, cervical cancer, and controls were 0 398?0 293, 1 580?0 819, 0 050?0 012 There was statistically significant difference among three groups ( P

Objective Genecology is making great progress in the 21th Century. At the same acupuncture will play and inportant role in the postgenome thmes. So it is considered that acupuncture mechanism have certain experence to draw on modern genetic theories and techniques, especially in crucial functional gene control. And the opinion ablut establishing acupuncture and geneti expression pedigree database is brorght up.

In this paper the causes of deficiency of public welfare were analyzed in medical research,and some strategies were proposed to enhance the public welfare of public health care services according to the cardinal principles of new healthcare reform package in 2009.These were benefit to maintain the public welfare of public medical and health care services,and to reach the goal of medical research served as the clinic and the patients.

Objective To elucidate the relationship between Ca2+/calmodulin-dependent protein kinaseⅡ(CaMKⅡ)and autophagy during the development of cardiac hypertrophy. Methods Rat embryonic cardiac cell line H9c2 cells was treated by angiotensin Ⅱ to establish cardiomyocyte hypertrophy model in vitro and using antagonists and gene function gain and loss to analyze AMPK-LC3Ⅱ autophagy signaling pathway. Results The phosphorylation of CaMKⅡ and autophagy related signaling-AMPK and autophagy marker LC3Ⅱ were rapidly increased by angiotensinⅡtreatment at early stage. However ,the above changes were highly blocked by CaMKⅡinhibitor and HDAC4 inhibition. Conclusion CaMKⅡ is the center factor of regulating cardiac hypertrophy ,it mediates autophagy through directly regulating AMPK or indirectly regulating HDAC4 during the development of cardiac hypertrophy.

As the demand of the research administration to the library is clear and periodical,there forms fixed information service modes based on the working procedures of the research administration.It includes the services for making research plans and constructing long- or short-term management systems,and peer communication andcoordination.

Objective: To investigate the intelligence development of the low birth weight babies and related factors. Method: The development ability of 190 low birth weight babies was assessed with the Revised Gesell Development Schedule. The result was compared with that of normal control. Result: The development quotients (DQ) of low birth weight infants in motor, adaptive and personal/social areas at 1 and 2 years of age and in language at 2 years of age were significantly lower than that of the normal controls. The stepwise regression analysis showed that all performances in motor, adaptive, language and personal/social areas were significantly related to age, sex, head circumstance, low birth weight and feeding way of infants, and education of their parents. Conclusion: Low birth weight infants have poorer intelligence at the age of 1 and 2 years than normal controls.

Objective To study the clinical value of heat shock protein (HSP)70 in the diagnosis of neonatal asphyxia and the correlation of HSP70 and Neonatal Behavioral Neurological Assessment (NBNA)score.Methods From January 2014 to June 2016,full-term neonates born in our hospital were enrolled in the study and assigned into mild and severe asphyxia groups.Normally delivered full-term infants were assigned to the control group.Blood from umbilical artery were extracted immediately after birth and HSP70 levels were detected using ELISA.The NBNA scores were recorded at the 7th,14th and 28th-day after birth.Results HSP70levels in both mild (n =46 )and severe (n =35 )asphyxia groups were significantly higher than the control group(n =50)[(14.4 ±2.7)ng/ml、(17.7 ±4.5)ng/ml than(11 .9 ± 2.3)ng/ml,P <0.05].The severe asphyxia group had even higher HSP70 levels than the mild asphyxia group (P <0.05).The NBNA scores of both asphyxia groups were significantly lower than the control group (P <0.05).The umbilical pH values of both two asphyxia groups were also significantly lower than the control group(P <0.05).Correlation analysis showed that HSP70 level was negative correlated with NBNA score (7th,14th,28th-day)(r =-0.574、-0.493、-0.208,P <0.05).The HSP70 level was negatively correlated with umbilical pH (r =-0.576,P <0.05).The area under curve(AUC)for HSP70 levels to predict asphyxia was 0.798(95%CI 0.722 ~0.874,P <0.05).Conclusions HSP70 level in umbilical cord blood can be used as an indicator for neonatal asphyxia.The more severe the asphyxia,the higher the HSP70 levels and the lower NBNA score and umbilical pH.
