ABSTRACT
Objective To investigate the service needs in relation to the related behavioral characteristics and reproductive health service for women receiving induced abortion in childbearing age in Wenzhou, providing reference for the protection of reproductive health in women of childbearing age. Methods A questionnaire survey was conducted among a total of 1 065 women of childbearing age who received artificial abortion in 12 medical institutions and maternal and child health care institutions in Wenzhou. Results Of the 1 065 women, 456 (42.82%) were under 24 years old, 609 (57.18%) were over 25 years old.815 (76.53%) with high school / technical secondary school degree or below, 250 (23.47%) with college degree or above.448 unmarried (42.07%), 617 married (57.93%).484 (45.45%) of first abortion and 581 (54.55%) of repeated abortion.Among the direct causes of abortion, 244 (54.46%) were not contraception, 382 (61.91%) were contraception failure.There was a significant difference in the direct causes of induced abortion among women with different marital status(χ2＝28.128, P < 0.05).67.51% of the surveyed women hoped that the family planning clinic would provide contraceptive and reproductive health consulting services after abortion. Conclusion Women of childbearing age with induced abortion in Wenzhou have low education level, high rate of repeated abortion, lack of contraceptive knowledge and high demand for contraceptive and reproductive health consulting services.Therefore, it is necessary to improve reproductive health education, popularize contraceptive knowledge, reduce abortion rate and promote reproductive health.
ABSTRACT
Objective To find out whether the effects of childhood physical abuse on internet addiction disorder in adolescence could be mediated by self-esteem.Methods 3798 high school students selected from 76 classes in Grade One and Grade Two,were asked to fill in the anonymous questionnaire,which including the demographic characteristics of students,Young' s Internet Addiction Scale,Parent-Child Conflict Tactics Scales and Rosenberg' s Self-Esteem Scale.Results Childhood physical abuse could directly predict less self-esteem and internet addiction disorder (r=-0.108,P＜0.01,r=0.057,P＜0.01 ) and had significant indirect effects on intemet addiction disorder which could be mediated through self-esteem (a=-0.703,standardized b=-0.104,z=5.052,P＜0.001 ).Self-esteem had mediated 22.5％ of the childhood physical abuse cases on their internet addiction disorders during the period of adolescence.Conclusion Self-esteem could partially mediate the relationship between childhood physical abuse and internet addiction disorder.The mediating roles of self-esteem suggested that salient leverage points could make a change through empowerment training,self-esteem group training on self-esteem enhancement in the stage of adolescence.
ABSTRACT
Objective To explore the correlation between induced abortion and reproductive tract infections (RTIs). Methods On the basis of keeping the representation of cities under study,53 652 fertile women aged 15-49 were surveyed by using a stratified-cluster-random sampling.Investigation and gynecological examination were conducted by two steps - firstly converging at the clinics, and then visiting those households for someone who did not show up at the clinics. Results Among all the 32.0% (n=16 800) women ever having experienced the history of induced abortion,21.1%(n= 11 090) of them had one, 7.6%(n=3976) women had two, and 4.1%(n=1734) women had at least three events. 59.0%(n=30 959) women among our studied samples had ever had RTI,with 30.9% ( n = 16 215 ) of them had only one 20.0% (n = 10 494 ) women had two and 8.1% (n =4250) had three or more RTIs. Data from x2 text and ordinal regression analysis revealed that the rural married women who underwent more induced abortions were more likely to suffer from RTIs,especially cervical infection and PID. Conclusion Our study showed that the rates of induced abortion and reproductive tract infections among married women in Anhui province were both high.Women who underwent induced abortions had a higher prevalence rate of reproductive tract infections.
ABSTRACT
Objective To study the relationship between emotional,physical abuse and internet addiction disorder(IAD)among middle school students.in order to lay foundation for the development of prevention and control programs on IAD.Methods Students selected from 76 classes in Grade One and Grade Two,filled out the anonymous questionnaire,which including demographic characteristics of students,Young's Intemet Addiction Scale,Parent-Child Conflict Tactics Scales.etc.Non-conditional multivariate logistic regression model was employed to explore the relationship between child abuse and IAD.Independent variable was child abUSe while dependent variable was IAD.Covariant variables would include demographic characteristics,as sex,age,style of household,et al.Results Among 3798 students,the overail prevalence of emotional abuse was 81.1%.with 55.1% of them reported having experienced physical abuse.Among 3507 intemet users,5.2%was diagnosed as IAD.Results from the nonconditional multivariate Iogistic regression model showed that odds ratio of severe physical abuse and moderate physical abuse were 3.02(1.63-5.58)and 4.00(2.01-7.93).Conclusion Moderate physical abuse and severe physical abuse were possible risk factors of IAD.

ABSTRACT
Objective To understand health seeking behavior and its influential factors to reproductive tract infections (RTIs) on women at reproductive age in the rural areas. Methods 54 540 fertile women aged 15-49 were surveyed by a stratified-cluster-random sampling method and gynecological examination were conducted in two steps: converging at the clinics, and then visiting their households, later, 31 624 women who had at least one RTI symptom were chosen. Results Among all the women at reproductive age, the rate of having at least one RTI symptom was 59.8% with the means of RTI symptom as 1.66±0.89. 15 989 women went to see doctors out of the 31 624 women who had RTI symptoms, with a proportion of 50.6 %. The results of logistic regressy showed that those women whose husbands having higher education level, higher income, more RTI symptoms and better knowledge on RTI were more easily to go to the hospitals. However, those women whose husbands working out of the county, having older first bearing age and more numbers of pregnancy were less likely to go to the hospitals. Reasons that refrained them from going to see a doctor would include: 2137(13.7%) did not know that RTI was a disease; 7443(47.6%) of them thought that every woman were bound to have at least one symptom and it did not matter; 1629 (10.4%) of them felt shameful; 349 (2.2%) learned that the diseases were incurable; 975 (6.2 % ) felt the cost of treatment was too expensive; 2101 (13.4 %) had no time; 1001 (6.4 %) would treat themselves through buying medicines over the counter. Conclusion RTI symptoms were quite prevalent among women at reproductive age but the rate of seeing a doctor was low and caused by multi-factors. Health education and gynecological census in increasing the curable rate of RTIs should to be strengthened.
ABSTRACT
<p><b>OBJECTIVE</b>To study the newborn's Apgar score in 'one minute' and relevant factors.</p><p><b>METHODS</b>One year inpatient woman from a Maternal and Child Health Hospital of Anhui province were selected by cluster sampling method and newborn asphyxia situation was investigated using Apgar score and self-designed questionnaire.</p><p><b>RESULTS</b>The Apgar score in 'one minute' which marking 8 to 10, 4 to 7 and 0 to 3 were found in 1875 (73.78%), 426 (16.77%) and 240 infants (9.45%) respectively. The average Apgar score in 'one minute' and five minutes were (7.69 +/- 2.27) and (9.01 +/- 1.89) respectively, The Apgar score in 'one minute' was significantly correlated with that of five minutes (Pearson coefficient correlation r = 0.841, P = 0.00). Ordinal regression analysis revealed that parturient age (OR = 1.04), being farmer (OR = 2.22), parity (OR = 1.26), assistant vaginal delivery (OR = 4.93), caesarean section (OR = 1.95), pregnancy-induced hypertension syndrome (OR = 1.42), albuminuria in gestational period (OR = 1.44), newborn being male (OR = 1.23), low birth weight (OR = 2.94), inborn abnormality (OR = 12.12), premature birth (OR = 1.22) and complications of delivery (OR = 5.04) were risk factors while the number of years under study (OR = 0.91), prenatal check-up (OR = 0.48), body length of newborn infant (OR = 0.88) and single birth (OR = 0.57) were protective factors.</p><p><b>CONCLUSION</b>Apgar score in 'one minute' of newborn infant was affected by several factors as stated above. Health care program in earlier period toward community parturient should be strengthened in order to discover and control high risk factors of duration of pregnancy in earlier period.</p>

Regulation of P2X7 receptor expression is of interest because activation of this receptor by extracellular ATP triggers a wide variety of cell functions in leukocytes. However, its expression and modulation in human peripheral blood mononuclear cells (PBMC) and monocytes remain unclear. RT-PCR was used to detect the constitutive level of P2X7 receptor and the levels upon stimulation with bacteria, bacterial product, mitogen and various cytokines in human PBMC and monocytes. P2X7 receptor mRNA was detected in PBMC and monocytes. P2X7 receptor expression in PBMC was up-regulated by interleukin-2, -4, -6 (IL-2, IL-4, IL-6) tumour necrosis factor-alpha (TNF-alpha), lipopolysaccharide (LPS) and heat-inactivated Staphylococcus aureus Cowan strain I (SAC). However, interferon-gamma (IFN-gamma), granulocyte-macrophage colony-stimulating factor (GM-CSF), macrophage colony-stimulating factor (M-CSF) and phytohemagglutinin-M (PHA-M) had little effect on the expression of P2X7 receptor. Furthermore, LPS and M-CSF could up-regulate P2X7 receptor expression in monocytes, while IFN-gamma, TNF-alpha and GM-CSF had weak effects, but pretreatment with these inducers could not further enhance LPS-stimulated P2X7 receptor expression in monocytes. The results obtained demonstrate that inflammatory stimuli drive P2X7 expression, thus supporting the hypothesis that P2X7 receptor may play a role in the inflammatory responses against bacteria infection, which need further verification.
