Objective To explore the correlation between personality traits in children and parental rearing patterns.Methods Two hundred and seventy-nine middle school students were investigated with egma minnenav bardndasnauppforstran(EMBU)and Eysenck personality questionnaire,and then Pearson correlation was analyzed.Results High positive correlation were found among scores of parental rearing patterns and those of neuroticism(N)and psychoticism(P).P score correlated significantly with parent's punishment,rejection and negative reaction,over interference and over protection,while high negative correlation with the score of parent's emotional warmth.N correlated significantly with parent's punishment,overprotection and rejection,high positive correlated the score of lie with parent's emotional warmth.Conclusion Parental rearing patterns play very important roles in children's personality development.

Objective To develop a child neglect scale with Chinese culture background to assess the status of the neglected children in China,and examine the reliability and validity of the child-neglect scale(CNS).Methods Considering the cultural background of China,an item pool was established by revising items in correlative literatures and scales.Then,the first draft of the CNS was improved by reserving the effective items well graded by professional experts.A total of 871 students from 2 junior high schools and a vocational and technical college were involved in the study.Those students were surveyed with Parental Rearing Patterns scale and child neglect scale.Exploratory and confirmatory factor analysis were applied to the development and evaluation of the structure of the scale.Results The findings were as follows:the general Cronbach′s Alpha reliability was 0.85,the split-half reliability was 0.81,the test-retest reliability was 0.90. The CNS was made of the 4 sub-scales which was safe neglect scale,physical neglect scale,communion neglect scale and affection neglect scale.the general Cronbach′s Alpha reliability of the child neglect scale was 0.79-0.85,the split-half reliability was 0.64-0.81,and the test-retest reliability was 0.82-0.90.The item loadings of the neglect scale were over 0.30.The confirmatory factor analysis indicated that the ratio of Chi-square to degrees of freedom were 1.766,the goodness of fit index was 0.917,the Tucker-Lewis index was 0.916,and the root mean square error of approximation was 0.047.Criterion-related validity studies indicated that the scores of the CNS were significantly correlated with the rearing patterns as well(r=0.049,-0.465 P

reliability, content validity, construct validity, and criterion - related validity of the CNS are entirely in accordance with the psychometric demands.

BACKGROUND: Whether nighttime surgery will affect the safety and prognosis of patients has been controversial. OBJECTIVE: To compare the safety and prognosis of daytime surgery versus nighttime surgery in patients receiving total knee arthroplasty. METHODS: Data of 712 patients who received unilateral total knee arthroplasty from January 2015 to January 2018 in the Binzhou Medical University Hospital were retrospectively analyzed. Of the patients, 615 cases were treated by total knee arthroplasty during daytime hours (8:00-18:00) and the other 97 patients were treated by total knee arthroplasty during nighttime hours (18:01-7:59). The perioperative and postoperative conditions of the two groups of patients were compared. This study was approved by the Medical Ethics Committee of Binzhou Medical University Hospital, China (approval No. LW2016013). RESULTS AND CONCLUSION: (1) Perioperative period: The operation time in the nighttime surgery group was shorter than that in the daytime surgery group (P < 0.05). The amount of intraoperative bleeding and 24 hours postoperative drainage were more in the nighttime surgery group than that in the daytime surgery group (P < 0.05) There was no statistically significant difference in blood transfusion rate, the incidence of deep vein thrombosis, postoperative infection rate, postoperative periprosthetic infection rate, postoperative fever rate, and length of hospital stay between the two groups (P > 0.05). (2) Prognosis: There was no significant difference in motion range and knee joint function KSS score between the two groups (P > 0.05). (3) The results showed that nighttime surgery did not increase the incidence of adverse reactions after total knee arthroplasty, and did not affect the prognosis of patients.

OBJECTIVETo evaluate the effect of Herba Epimedii Brevicornus (HEB) and prepared Radix Rehmannia (RR), the representative Chinese herbs for warming yang and nourishing yin on glucocorticoid receptor (GR) in GR down-regulated rats.

METHODSThe GR down-regulated model was established by subcutaneous injection of hydrocortisone. Seventy-two SD male rats were randomly divided into four groups: the normal group; the model group (MG) ; the HEB group, and the RR group. And every group was subdivided to 3 batches depending on the time points (the 3rd, 7th and 14th day after modeling) of observation, with 6 rats in each batch. Changes in blood level of corticosterone (GS), as well as protein expression and binding power of GR in splenic lymphocytes at corresponding time points of the batches were determined by RIA and flow cytometry.

RESULTSNo significantly difference was found in blood GS levels of the model group at all the time points, as compared with that of the normal group (P > 0.05), while that in the RR group was significantly lowered at the 14th day, and showed significant difference from that in the model group (P < 0.05). The protein expression and binding power in the model rats were lower than those in normal ones (all P < 0.01), but they were significantly higher on the 7th and 14th day in the RR group (P < 0.01), and on the 14th day in the HEB group higher than those in the model group, respectively (all P < 0.01).

CONCLUSIONBoth HEB and RR, in dosage-form of water decoction, could up-regulate the protein expression and binding power of GR in GR down-regulated model rats, but different in acting time.

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.

METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.

RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).

CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.

Objective To explore the parental personality traits and affective expression in abuse children.Methods The investigation was carried out in 3 villages in Xinxiang,Henan province,with a total of 1 310 households,of which there were altogether 370 households that had children at 10-15 years old.From them,200 households were randomly selected to screen the children for child abuse,and the Eysenck Personality Questionnaire (EPQ) and Toronto Alexithymia Scale(TAS) assessment were made among the parents who were primary caregi-vers.Independent samples t-test and Chi-square test were conducted to the 196 valid questionnaires.Results The average educated years of parents in abuse group and non-abuse group were (7.75?5.437)years old and (7.28? 2.532) years old,there was no significant diffe-rence (P=0.413).The average age of fathers in abuse group and non-abuse group were (36.16?8.96)years and (39.06?7.99)years repectively,there was no significant difference(P=0.170),and those of mothers in both groups were (36.06?5.15)years and (37.62?5.70) years respectively,there was no significant difference(P=0.121).There were 31 fathers and 49 mothers who were guardian in abuse group,while there were 35 fathers and 81 mothers in non-abuse group (?2=1.56 P=0.212).No significant differences were found in parental psychoticism [t(father)=1.221 P= 0.227;t (mother)=-0.471 P=0.639],neuroticism[t (father)=-0.524 P=0.602;t(mother)=-0.556 P=0.579],extraversion/ introversion[t(father)=-0.449 P=0.655;t(mother)=-0.859 P=0.392] and lie [t(father)=-1.263 P= 0.211;t(mother)=0.733 P= 0.465],the ability to identify and describe feelings[t(father)=0.946 P=0.348;t(mother)=0.815 P=0.417],to distinguish between bodily sensations[t(father)=0.215 P=0.831;t(mother)=2.107 P=0.037],to daydream [t(father)=-0.088 P=0.930;t(mother)=-0.971 P=0.333]and to focus on externally oriented thinking[t(father)=-0.648 P= 0.519;t(mother)=-0.164 P= 0.870] in TAS.Conclusions In a general way parents who abuse their children do not necessarily have problems with their personalities or affective expression.Not only abnormal parents are likely to assault their children,but also normal parents may do it as well.

Introduction:The 2010 targets of the China Hepatitis B Prevention Programme were a prevalence of hepatitis B surface antigen (HBsAg) less than 1.0% for children less than five years old and less than 6.0% for the total population. This survey assessed the prevalence of Hepatitis B infection in Lianyungang, Jiangsu province, China in 2009–2010.Methods:Multistage sampling was used with 2372 subjects among 17 selected villages. Blood specimen collection and testing by enzyme-linked immunosorbnet assay (ELISA) were completed using the following markers for hepatitis infection: HBsAg and antibody to HBsAg (anti-HBs); hepatitis B e antigen (HBeAg) and antibody to HBeAg (anti-HBe); and hepatitis B core antibody (total anti-HBc). The data were analysed with Epi Info, version 3.3.2.Results:The prevalence of HBsAg was 2.4% (95% Confidence Interval [CI]: 1.8–3.0; Adjusted Prevalence [AP] 2.9%); anti-HBs prevalence was 51.1% (95% CI: 49.1–53.1; AP 49.2%) and total anti-HBc prevalence was 41.7% (95% CI: 39.8–43.7; AP 45.5%). The prevalence of HBsAg and total anti-HBc positivity increased from young to older age groups, yet the prevalence of anti-HBs positivity decreased from young to older age groups (P< 0.001 for all). There was no difference in the prevalences of HBsAg and anti-HBs among females and males (P= 0.108 and 0.089), but females had a higher prevalence than males for total anti-HBc positivity (P< 0.001). Discussion: This survey showed that in 2010 the prevalence of HBsAg among children aged less than five years was lower than the national target of 1.0% and that the prevalence of HBsAg for the total population was lower than the national target of 6.0%.

OBJECTIVETo study the mutagenicity and teratogenicity induced by ammonium dinitramide(ADN).

METHODSAccording to technical specifications for toxicity determination of chemicals, Salmonella typhimurium reverse mutation assay (Ames assay), in vivo mammalian erythrocyte micronucleus test, sperm malformation test and teratogenesis test were used to detect the mutagenicity and teratogenicity induced by AND.

RESULTSWhen the exposure doses of AND were 8-5000 pg/plate, the result of Ames assay was negative. As compared with control group, the micronucleus rate of mice exposed to 113.8 mg/kg AND significantly increased(P<0.05), the sperm malformation rates of mice exposed to 54.4-272.0 mg/kg AND did not increased significantly. The survival rate of fetuses decreased, the rate of assimilated fetuses increased, the rate of fetus sternum agenesis enhanced in mice exposed to 319 mg/kg AND, as compared with controls. The rates of in the 4th-6th fetus sternum agenesis in groups exposed to 21.3, 79.7 and 319 mg/kg AND were higher than that in control group. The malformation rate of fetus bowels in groups exposed to 319 mg/kg AND was higher than that in control group. The teratogenic index of ADN was 30.

CONCLUSIONAND may be a mutagen and induce the teratogenic effect.
