Objective: To explore the possible relationships of adolescent personality traits, personality deviation and parental rearing pattern. Methods: 393 students from a high school in ShanDong were tested by PACL and EMBU. Re- sults: Generally, adolescent personality traits showed different profiles while factors of EMBU varied in different levels; Antisocial personality deviation was greatly influenced by parental warmth and understanding factor, father's punishment and rigor, father's overprotection. Schizoid personality deviation was mainly influenced by parental warmth and under- standing. Passive- aggressive personality dysfunction was influenced by father's warmth and understanding. Conclusion: Adolescent personality deviation is greatly influenced by parental rearing.

Objective:To investigate the feasibility of using shear wave dispersion (SWD) imaging in evaluating acute graft-versus-host disease (aGVHD) of the liver.Methods:A total of 42 Wistar rats were used as receptors and 10 Fischer 344 rats were used as donors for bone marrow transplantation to establish aGVHD models. Six rats were randomly selected every week for clinical observation and scoring. Then, ultrasonic SWD was performed to obtain shear wave speed (SWS) and shear wave dispersion slope (SWDS). Then, the histological characteristics were used as a reference standard, and the rats were divided into two groups: the group without aGVHD (nGVHD group) and the group with aGVHD. The differences in the clinical score and SWD values between the two groups were compared, the meaningful indexes were screened by binary Logistic regression analysis, and the joint prediction parameters were obtained. The ROC curve was plotted and the diagnostic efficiency was compared. The correlations between SWS, SWDS, clinical score and pathological grade were analyzed.Results:Clinical score, SWS, and SWDS in aGVHD group were higher than those in the nGVHD group (all P<0.05). The correlation between SWDS and pathological grade ( r=0.774, P<0.001) was higher than those between SWS, clinical score and pathological grade ( r=0.579, P=0.005; r=0.452, P=0.034). Logistic regression showed that SWDS was a significant indicator. In addition, the AUC values determined by SWDS and predictive parameters were (0.859, 0.886), which were significantly higher than the AUC of the clinical score (0.760, P<0.05). Conclusions:SWD imaging technology may become a promising method to evaluate hepatic aGVHD.

OBJECTIVETo accomplish a kind of therapeutic gene for hemophilia A, and observe the expression of human factor VIII (hF VIII) in vivo.

METHODSHuman clotting factor VIII cDNA with B-domain deleted (Delta760aa approximately 1639aa) was inserted into vector pRC/RSV to form pRC/RSV-hF VIII BD, which conjugated with in vivo liposome transfection reagent (DOTAP-Cholesterol) to accomplish a kind of therapeutic gene, pRC/RSV-hF VIII BD-DOTAP-Cholesterol. Mice were injected with pRC/RSV-hF VIII BD-DOTAP-Cholesterol i.m. and sacrificed 48 hours, 10 days, 20 days, 30 days, 40 days and 50 days later, respectively. Tissues such as heart, liver, spleen, lung, kidney and muscle were harvested, the distribution and transcription as well as expression of hF VIII BD cDNA were detected by means of PCR, RT-PCR and immunohistochemistry techniques. In addition, the antigen and antibody of hF VIII in plasma were measured.

RESULTSThere was high expression of hF VIII in plasma and tissues at the 48(th) hour after injection. On day 10, antigen level of hF VIII in plasma reached its peak, 17.55 ng/ml, and gradually reduced later. The antibody of hF VIII in plasma emerged on day 10 after injection, and increased and gradually reached 37.06 U/ml on day 50 after injection. PCR, RT-PCR and immunohistochemistry showed that hF VIII BD cDNA and its transcription as well as expression existed in all kinds of tissues, and lasted longer in spleen, lungs and kidneys than in heart, liver and muscle.

CONCLUSIONTherapeutic gene, pRC/RSV-hF VIII BD-DOTAP-Cholesterol, produced by combination of pRC/RSV-hF VIII BD and DOTAP-Cholesterol liposome can express human F VIII successfully in vivo, which lays an experimental foundation for curing hemophilia A by gene-drug in clinic.

Objective:To explore the effects of neonatal stimulator of interferon genes (STING) innate immune signaling pathway of HBsAg-positive mothers on non/hypo-response to hepatitis B vaccine (HepB) in their infants.Methods:From November 2019 to June 2022, HBsAg-positive mothers and their infants in the Third People's Hospital of Taiyuan were recruited as the study subjects. The epidemiological and clinical data were collected by questionnaire survey and medical records review. The key molecular proteins of STING innate immune signaling pathway (STING, pIRF3) and immune cells associated with vaccine response (DC, T and B and plasma cells) in neonatal cord blood were detected by flow cytometry. Follow up was conducted for infants for 1-2 months after the full vaccination of HepB. Serum hepatitis B surface antibody (anti-HBs) was detected by chemiluminescence microparticle immunoassay. Unconditional logistic regression model, nomogram and Bayesian network model were used to evaluate the effect of STING innate immune signaling pathway on non/hypo-response to HepB and related factors in infants, and the relationship between various factors.Results:A total of 195 pairs of HBsAg-positive mothers and infants were recruited, the rate of non/hypo-response to HepB in the infants was 12.31% (24/195). High maternal HBV DNA load, low expression of neonatal STING, low expression of pIRF3 and low percentage of plasma cells were risk factors for non/hypo-response to HepB in the infants ( OR=4.70, 3.46, 3.18 and 2.20, all P<0.05). The nomogram constructed by these factors had good predictive efficacy (area under curve=0.81, 95% CI: 0.63-0.83). The results of Bayesian network model showed that the infants with a high maternal HBV DNA load had a higher conditional probability of low STING expression (62.50%) and a higher conditional probability of low pIRF3 expression (58.54%). The conditional probabilities of low expression of DC, T, B and plasma cells were 53.16%, 60.20%, 68.42% and 57.14%, respectively. Conclusion:Maternal HBV DNA might inhibit STING innate immune signaling pathways in infants and immune cells associated with HepB response, resulting in non/hypo-response to HepB in infants of HBsAg-positive mothers.
