Aim To explore the effects and mechanism of ginsenoside-Rg1 on SK-N-SH cells treated with chronic morphine and naloxone-precipitated withdrawal. Methods Cells were pretreated with ginsenoside-Rg1 1,2,4,8,16,32 ?mol?L-1 for 24 h,then incubated for 24 h with morphine ( 100 ?mol?L-1 ) . MTT colorimetr was used to study the effects of ginsenoside-Rg1 on the multiplication of the cells treated with chro-nic morphine. After stimulated by the same concentra-tion of morphine,cells were added with different concentrations of Rg1 1,2,4 ?mol?L -1 for 24 h before stimulated with 10 ?mol?L -1 NAL. Fuorospectrophotometry RT-PCR and Western blot techniques were used to detect the effects of ginsenoside-Rg1 on the [Ca2+ ]i,CaMKⅡ ? mRNA and protein expression of the SK-N-SH cells treated with chronic morphine and naloxone-precipitated withdrawal. Results ① Compared with control group,morphine significantly inhibited cell multiplication and resulted in calcium overload,and the expression of CaMKⅡ-? mRNA and protein noticeably increased ( P

Objective To explore the association between urinary lactate/creatinine ratio and neonatal asphyxia,and to clarify the application value of urinary lactate/creatinine ratio in forecasting the hypoxie-ischemic encephalopathy (HIE)in neonates.Methods Using case-control study design method,40 cases of neonatal asphyxia infants were selected as asphyctic group and 40 healthy infants were used as control group.The urinary lactate/creatinine ratio in the first day after birth, urinary N-Acetyl-β-D-glucosaminidase (NAG)/creatinine and the score of Apgar of 80 infants were detected.The relationship between the urinary lactate/creatinine ratio,urinary NAG/creatinine ratio, as well as the score of Apgar and HIE were analyzed and compared in asphyctic group and control group.Results The Apgar scores at 1 and 5 min in asphyctic group were significantly lower than those in control group (P<0.01). The urinary lactate/creatinine ratio and urinary NAG/creatinine ratio in asphyctic group 1 d after birth were significantly higher than those in control group(P<0.01).There was significantly negative correlation between the urinary lactate/creatinine ratio and the 1-min and 5-min Apgar scores(r=-0.636,P<0.001;r=-0.883,P<0.01),but there was a significantly positive correlation between the urinary lactate/creatinine ratio and urinary NAG/creatinine ratio(r=0.433,P<0.01).Conclusion The urinary lactate/creatinine ratio may have decisive roles in prognosis evaluation of neonatal asphyxia,and so as the important foundation for the prediction of HIE.

Objective: To investigate the awareness and identify the influencing factors of sexual knowledge among primary and middle school students in Butuo County, Sichuan Province, so as to provide insights into sex education. Methods: Six primary and middle schools were randomly sampled from 40 primary and middle schools in Butuo County using the cluster sampling method on March and April, 2021, and a class was randomly sampled from each of grades 4 to 6 of primary schools and grades 1 to 3 of junior high schools, with all students from the class as study subjects. Students' demographic features and awareness of sexual knowledge were investigated using self-designed questionnaires, and the factors affecting the awareness of sexual knowledge were identified among primary and middle school students using multivariable linear regression analysis. Results: A total of 980 questionnaires were allocated, and 957 valid questionnaires were recovered, with an effective recovery rate of 97.65%. The respondents included 458 boys ( 47.86% ) and 499 girls ( 52.14% ), and included 908 students with Yi Ethnicity. The respondents included 802 primary school students ( 83.80% ) and 155 junior high school students ( 16.20% ). The awareness of sexual knowledge was 21.94% among the primary and middle school students, and their sexual knowledge was predominantly derived from parents ( 338 students, 35.32% ) and teachers ( 335 students, 35.01% ). The awareness of sexual knowledge was significantly lower in boys than in girls ( 17.69% vs. 25.86%; χ2=8.344, P=0.004 ), and the awareness of sexual knowledge appeared a tendency towards a rise with age ( χ2trend = 63.908, P<0.001 ). Low awareness of sexual knowledge was seen in students with fathers going out for labor ( 19.54% ), mothers going out for labor (11.24%) and living in the countryside ( 14.32% ) ( χ2=7.790, 9.224 and 34.144, all P<0.01 ). Multivariable linear regression analysis showed that students living in the countryside, students’ mothers going out for labor, ages of 12 to 14 years and ages of over 14 years were factors affecting the score of sexual knowledge ( β'=-0.072, 0.341, 0.645 and 0.843, all P<0.05 ). Conclusions The awareness of sexual knowledge is low among primary and middle school students in Butuo County. Health education of sexual knowledge should be emphasized on male students, those living in the countryside and students with mothers going out for labor.

Objective To study the effects of early mechanical strain magnitude on formation and differentiation of osteoclasts. Methods RAW 264.7 cells induced by macrophage colony-stimulating factors and osteoclast differentiation factors were subjected to 0, 1 000, 1 500, 2 000, 2 500 and 5 000 με mechanical straining for three days. The morphological changes, number of osteoclasts and proliferation of precursor cells were determined at day 7. The activity of the tartrate-reaistant acid phosphatase (TRAP) in the culture medium was detected at days 4 and 7. Results The number of osteoclasts was decreased in 2 500 με group, while it was increased in 5 000 με group. The proliferation of precursor cells was increased in 2 000 and 2 500 με group, while it was decreased significantly in 5 000 με group. There was no significant difference in the number of osteoclasts and proliferation of precursor cells among 1 000 με group, 1 500 με group and 0 με group. The activity of TRAP was decreased in 1 000, 1 500, 2 000, 2500 and 5 000 με groups at days 4 and 7 when compared with με group. Conclusions Early mechanical straining plays a direct role in formation and differentiation of osteoclasts. The high strain magnitude within physiological load inhibits osteoclast formation, while high strain magnitude beyond physiological load stimulates osteoclast formation. Low strain magnitude has nearly no impact on formation of osteoclasts. Early mechanical straining may inhibit differentiation of osteoclasts.

Objective To evaluate the validity and reliability of learning attitude scale among nurses in continuing nursing education in hospital.Methods We designed a nurse learning attitude scale in continuing education on the basis of a learning attitude questionnaire for teacher-training by Jiao Weiting. In July 2015, totally 207 nurses of the Third Hospital of Mianyang who received continuing education in hospital were selected as the research object by cluster sampling method. We investigated their learning attitudes. The reliability of the scale was assessed by Cronbach's α coefficient and test-retest reliability. The validity was assessed by factor analysis and Pearson's correlation.Results The test-retest reliability of the scale were as the following:cogni-tive level (0.82),experience of emotion (0.89),tendency of behavior (0.91),total scale (0.88);Cronbach's α co-efficients were as the following:cognitive level (0.85),experience of emotion (0.94),tendency of behavior (0.83), total scale (0.89). According to the result of Pearson's correlation,the total scale of learning attitude exhibited a positive correlation with cognitive level,experience of emotion and tendency of behavior (P<0.01). Four prin-cipal components were extracted by factor analysis and the constructs of the instrument obtained were consistent with the conceived concept in essence.Conclusions The scale learning attitude could measure the learning attitude of nurses in continuing nursing education with better reliability and validity.
