Objective To construct lentiviral expression vector of rat IP3R1 gene,and identify its silencing effect by using PC12 cell lines. Methods Oligo DNA sequences of 4 pairs of miRNA,named as miRNA1,miRNA2,miRNA3 and miRNA4,were designed according to IP3R1 gene sequence (GenBank:NM_001007235). The single strand of oligo DNA was annealed to form double strand DNA,and then connected with the empty plasmid pcDNA TM 6.2-GW/EmGFP-miR. By using gateway technology,the expression vector pcDNA TM 6.2-GW/EmGFP-miR-IP3R1 was linked into lentiviral destination vector pLenti6/V5-DEST to form the lentiviral expression vector pLenti6/V5-DEST-IP3R1,then it was transformed into infectious lentiviral particles and to infect PC12 cell lines. Silencing effect of gene IP3R1 was detected by Real-time PCR and Western blot. Results The sequence of expression vector pcDNA TM 6.2-GW/EmGFP-miR-IP3R1 was proved correct using sequencing method. After the transfection of letivirus vector pLenti6/V5-DEST-IP3R1 into PC12 cell lines,the IP3R1 mRNA and protein level were down-regulated 48h later,of which miRNA2 and miRNA3 sequence showed the best silencing effect,and the expression of IP3R1 in the blank control and negative control showed no significant changes. Conclusions Lentiviral expression vector pLenti6/V5-DEST-IP3R1 was constructed successfully. pLenti6/V5-DEST-IP3R1 may render the IP3R1 expression in PC12 cell lines down-regulated,and it provides a foundation for studying the function of calcium release channel IP3R1.

BACKGROUND: It is the most effective and economical method to reduce the incidence of stroke by conducting the health education concerning the etiological factors or risk factors and therapeutic knowledge of hypertension, diabetes mellitus and hyperlipidemia among the public and improving their knowledge level about the prevention and treatment of stroke.OBJECTIVE: To investigate the cognition of the knowledge concerning the prevention and treatment of stroke among the public in Dongguan area.DESIGN: A cluster sampling and simple randomized sampling survey.SETTINGS: Department of Neurology, the Fifth Affiliated Hospital of Sun Yat-sen University and the Department of Neurology, Affiliated Tungwah Hospital of Sun Yat-sen University.PARTICIPANTS: Between March and June in 2001, totally 2 500 cases were randomly selected by means of cluster sampling combined with simple randomized sampling from the residents and migrant populations no younger than 17 years old in the government organization, enterprises, factories of various forms, Dongguan University of Technology and senior middle schools of urban and rural Dongguan city and the administrative villages of the rural areas of Dongguan city in Guangdong province before March 2003.METHODS: The inventory was modified according to relevant literatures,including demographic data, general knowledge of stroke, and knowledge about the prevention, identification and treatment of stroke, and the pathway to obtain knowledge about the prevention and treatment of stroke.Each item for the knowledge about the prevention and treatment of stroke was marked as 1-4.5 points, and the total score was 60. There was no mark for the pathway to obtain knowledge about the prevention and treatment of stroke. One unit was investigated each time, and 300-600 questionnaires were sent out, 500 questionnaires were randomly handed out to the healthy physical examinees in the Tungwah Hospital.MAIN OUTCOME MEASURES: The correct rate of answers to the questionnaire, the total score of each kind of knowledge about the prevention and treatment of stroke, the total score of each kind of knowledge in the subgroups, and the pathways to obtain knowledge about the prevention and treatment of stroke were mainly observed.RESULTS: Totally 2 320 complete and effective questionnaires were collected back. ① The average correct rate of answers to all the questions was 49.80%, and those of knowledges about identification and treatment were lower, the total score was ＜ 60% in 48.20% of the subjects. ② The level for each knowledge about the prevention and treatment of stroke was lower in males than in females (P ＜ 0.05), but higher in the middle-age and old groups than in the young group (P＜0.05), and it was decreased from various civil servants, free agents, workers, farmers and students in order (P＜0.05), and there was significant difference between students and free agents (P＜0.01); it was also decreased in order from higher educational level to middle and lower ones in order (P＜0.05); it was also higher in the subjects with stroke history than in those without (P ＜ 0.05). ③) After the subjects were subdivided according to gender, age, profession and educational level, the pathways to obtain knowledge about the prevention and treatment of stroke in order were reading newspapers and magazines,watching TV, reading handbooks about science popularization, influence from relatives and friends, promotion and education of medical staff, and the last one was the least in all the groups.CONCLUSION: The level for the knowledge about the prevention and treatment of stroke was lower among the public in Dongguan area during the investigation, especially the knowledges about identification and treatment, so proper measures should be adopted to further develop education on the knowledge about the prevention and treatment of stroke.

Objective:To analyze the impact of adolescent pregnancy on maternal and infant outcomes.Methods:A retrospective cohort study was conducted on 5 765 parturbirths in Jining Medical College Hospital from January 1, 2019 to December 31, 2020. The parturbirths were divided into adolescent group (maternal age<20 years, 280 cases), age group 1 (maternal age 20-24 years, 1 733 cases) and age groups 2 (maternal age 25-34 years, 3 752 cases). All information was collected through the hospital′s electronic case system. General data, pregnancy characteristics and outcomes were compared among the three groups by analysis of variance (ANOVA), χ 2 tests and binary logistics regression analysis was used to analyze the impact of adolescent pregnancy on maternal and infant outcomes. Results:In the adolescent group, the proportion of women with an education of junior high school or below, rural residence, no fixed income, unmarried, and no history of induced abortion were all significantly higher than those in age group 1 and age group 2 (82.50% vs 17.37%, 14.37%; 59.29% vs 42.70%, 43.36%; 80.71% vs 15.52%, 14.71%; 75.71% vs 12.23%, 9.97%; 82.50% vs 71.84%, 71.91%) (all P<0.05); there was no significant differences in age at menarche, body mass index before pregnancy, and weight gain during pregnancy among the three groups (all P>0.05). The proportion of preterm birth, low birth weight infants and transferring to neonatal intensive care unit (NICU) in the adolescent group were all significantly higher than those in age group 1 and age group 2 (5.36% vs 1.10%, 1.57%; 5.00% vs 0.23%, 0.05%; 21.79% vs 6.12%, 15.17%); the incidence of anemia in pregnancy in the adolescent group was significantly higher than that in age group 1 (15.36% vs 9.75%), and the incidence of postpartum hemorrhage was significantly higher than that in the age group 2 (10.71% vs 6.08%). The incidence of failed vaginal trials leading to cesarean section, amniotic fluid contamination, and episiotomy was significantly lower in the adolescent group than those in age group 2 (8.57% vs 15.22%, 10.71% vs 18.10%, 33.95% vs 40.01%) (all P<0.05). The incidence of failed vaginal trials leading to cesarean section was inversely associated with gestational age (adolescent group, OR=0.252, 95% CI: 0.123-0.515; age group 1, OR=0.673, 95% CI: 0.567-0.799) (both P<0.05); the risks of low birth weight infants (adolescent group, OR=7.440, 95% CI: 3.426-16.156; age group 1, OR=0.103, 95% CI: 0.032-0.330) and transferring to the NICU (adolescent group, OR=1.661, 95% CI: 1.120-2.463; age group 1, OR=0.360, 95% CI: 0.290-0.448) showed a U-shaped distribution in different pregnancy age groups, they were both higher in the adolescent group than those in the age group 2 (both P<0.05); the risk of episiotomy (adolescent group, OR=0.002, 95% CI: 0-0.016; age group 1, OR=1.308, 95% CI: 1.151-1.485) showed an inverted U-shape distribution across the different pregnancy age groups, it was lower in the adolescent group than that in age group 2 (both P<0.05). Conclusion:Adolescent pregnancy is associated with a lower risk of conversion to cesarean section and episiotomy due to failed vaginal delivery, but may increase the risk of low birth weight infants and transferring to NICU.
