ABSTRACT
【Objective】 To investigate the prevalence and influencing factors of feeding difficulties in preterm infants at weaning and self-feeding transition stage, so as to provide a scientific basis for the management of feeding preterm infants. 【Methods】 Preterm infants at corrected age of 6 - 24 months were recruited from the Department of Child Health of five maternal and child health hospital of Chengdu from April to May 2021, and were surveyed by using the Chinese Version of the Montreal Children Hospital Feeding Scale (MCF-FS) and the self-designed questionnaire on the influencing factors of feeding difficulties. Then the status quo of feeding difficulties and its influencing factors were analyzed. 【Results】 The prevalence rate of feeding difficulties in 231 preterm infants was 32%. Among them, the prevalence rate of mild, moderate and severe feeding difficulties was 15.2%, 7.8% and 9.1%, respectively. Binary Logistic stepwise regression analysis indicated that food allergy (OR=4.253, 95%CI: 1.430 - 12.649), anxious mood of caregivers (OR=6.064, 95%CI: 2.998 - 12.268), tease or chase during eating(OR=2.873, 95%CI: 1.382 - 5.970), recreational activities at eating (OR=2.328, 95%CI: 1.115 - 4.860), and forced feeding (OR=2.772, 95%CI: 1.239 - 6.198) were positively associated with feeding difficulty of preterm infants(P<0.05). 【Conclusion】 Feeding difficulties in the weaning and self-feeding transition period of preterm infants are prevalent, so the guidance should focus on premature infants with food allergy, anxious caregivers and improper feeding behaviors, and appropriate interventions should be taken to promote scientific feeding.

ABSTRACT
The traditional Chinese medicine (TCM) in pediatric care has a long history,proven efficacy,and distinctive characteristics.The China Association of Chinese Medicine has organized a series of youth salons to discuss the clinical advantages of treating diseases.Experts at this seminar proposed that the superior disease categories in pediatric TCM are significant for showcasing the unique strengths and advantages of TCM in the treatment of pediatric diseases,enhancing diagnostic and treatment levels,inheriting TCM knowledge,promoting the integration of TCM and Western medicine,and meeting patients' needs.The strengths of pediatric TCM are summed up as "having what others do not,excelling at what others have,being special in what others excel at,and ensuring safety in what others specialize in." The scope of superiority in pediatric TCM covers multiple systems,including respiratory,digestive,endocrine,psychological,and dermatological systems.This article summarized the advantages of TCM in treating 13 diseases discussed in the salon,such as upper respiratory tract infections,coughs,pneumonia,allergic rhinitis,bronchial asthma,atopic dermatitis,functional dyspepsia,functional constipation,enuresis,marginal short stature,simple obesity,attention deficit hyperactivity disorder,and tic disorders.The overall advantages were reflected in three aspects:First,the holistic concept and treatment based on syndrome differentiation in TCM highlight the advantage of treating the root causes of diseases,making the treatment methodical and precise.Second,most traditional Chinese herbs are natural and have strong safety profiles.Third,TCM treatment methods are abundant,especially the external treatment methods,which are widely used in pediatrics,highly accepted by parents,and have definite efficacy,as well as good safety and compliance.
ABSTRACT
【Objective:】 The co-word analysis method was used to analyze narrative medical literature studied in China in the past 10 years to explore the research status in this field and lay a foundation for further research. 【Methods:】 Using "narrative medicine" as the theme term, with the limited time interval of 2013—2022 to retrieve for relevant literature in CNKI, Wanfang, and VIP databases, and include literature that meets the research standards. Bicomb2 was used to perform keyword statistics and analysis on the downloaded literature. Ucinet6.0 and Netdraw were used to draw co-occurrence analysis graphs to visualize the co-occurrence relationship between high-frequency keywords. 【Results:】 A total of 565 papers were included and 31 high-frequency keywords were extracted. The co-occurrence relationship diagrams showed that the current research hotspots of narrative medicine in China include traditional Chinese medicine, nursing, general practice, evidence-based medicine, medical ethics, hospice care, chronic diseases, cancer and other popular disciplines and diseases. Most of them were about enhancing the empathy and humanistic caring ability of medical personnel and improving doctor-patient communication to improve the doctor-patient relationship, as well as doing well in medical humanities education and cultivating narrative ability through parallel medical records and reflective writing. The research on gerontology, improving the professional identity of medical staff, integrating literature and medicine, and the impact on patients were relatively few. 【Conclusion:】 At present, narrative medicine in China has achieved many achievements in fields such as nursing, traditional Chinese medicine, general practice medicine, chronic diseases, cancer, medical humanities education, and improving doctor-patient relationships. In the future, in-depth exploration can be conducted from the use of narrative medicine in multi-disciplinary and disease fields, trying different training methods, and synchronous cultivation of teachers and students, so as to build a more comprehensive narrative medicine system.
ABSTRACT
Objective:To explore the application effect of parent-child emotional regulation and resilience group training in adolescent depression patients.Methods:From August 2020 to September 2021, a total of 118 adolescent depression patients were enrolled and randomly divided into the intervention group(66 cases) and the control group(66 cases) by a random number table method.The intervention group received medication therapy and parent-child group emotional regulation and psychological resilience training, while the control group received medication therapy and commonly used individual, family or group therapy in clinical practice.The Hamilton Depression rating scale(HAMD-24 version), Herth hope scale(HHS), Connor-Davidson resilience scale(CD-RISC), and family adaptability and cohesion evaluation scale, second edition Chinese version(FACES-Ⅱ-CV) were adopted to investigate participants at baseline, 12-week, 24-week, and 36-week after intervention.SPSS 26.0 statistical software was used to perform repeated measurement analysis of variance on the data.Results:(1)The interaction effect between two groups of HAMD scores( F=54.0, P<0.001), group main effect( F=401.4, P<0.001), and time main effect( F=116.6, P<0.001) were all significant.Further simple effect analysis showed that there were statistically significant differences in HAMD scores at various time points after intervention between the intervention group(26.2±6.5, 19.3±5.9, 11.3±5.6) and the control group(33.1±9.1, 30.3±7.9, 25.0±8.4)(all P<0.05). Intragroup comparison showed the HAMD scores of the intervention group and control group at each time point after intervention were lower than those before intervention (all P<0.05). (2)The interaction effect of CD-RISC scores between two groups of patients( F=72.1, P<0.001), group main effect( F=48.9, P<0.001), and time main effect( F=174.9, P<0.001) were significant.Further simple effect analysis showed that the CD-RISC score of the intervention group at each time point after intervention were higher than those of the control group(all P<0.05). Intragroup comparison showed the scores of CD-RISC at each time point after intervention in the intervention group and the control group were higher than those before intervention(all P<0.05). (3)The interaction effect of HHS scores( F=121.6, P<0.001), group main effect( F=57.4, P<0.001), and time main effect( F=208.1, P<0.001) of the two groups of patients were significant.Further simple effect analysis showed that the HHS scores of the intervention group were higher than those of the control group at all time points after intervention(all P<0.05). Intragroup comparison showed the HHS scores of the intervention group and the control group at each time point after intervention were higher than those before intervention(all P<0.05). (4)The interaction effect of FACES-Ⅱ-CV scores( F=45.0, P<0.001), group main effect( F=20.3, P<0.001), and time main effect( F=154.5, P<0.001) of the two groups of patients were significant.Further simple effect analysis showed that the FACES-Ⅱ-CV scores of the intervention group were higher than those of the control group at all time points after intervention(all P<0.05). Intragroup comparison showed the FACES-Ⅱ-CV scores of the intervention group and the control group at each time point after intervention were higher than those before intervention(all P<0.05). (5)The total effective rate of the intervention group was higher than that of the control group(95.1%, 87.7%)( P<0.001). Conclusion:In adolescents with depression, parent-child group emotional regulation and resilience training can effectively reduce depression emotion, increase the level of hope and resilience of patients and enhance family intimacy and adaptability.
ABSTRACT
We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.

Objective:To investigate the effects of long non-coding RNA (lncRNA) Gm13568 on the activation of A1 astrocytes and the progress of experimental autoimmune encephalomyelitis (EAE) in mice.Methods:A recombinant lentiviral vector (LV-Inhibit-Gm13568) carrying astrocyte-specific promoter of glial fibrillary acidic protein (GFAP) was established to inhibit the function of endogenous Gm13568. A control vector (LV-ctrl) was established as well. The recombinant vectors were packaged. C57BL/6 mice were injected with 1×10 7 transforming units of viral suspension via the tail vein and 7 d after the injection, myelin oligodendrocyte glycoprotein 35-55 (MOG 35-55) was used to establish the mouse model of EAE. Four groups, PBS group, EAE group, LV-ctrl+ EAE group and LV-Inhibit-Gm13568+ EAE group, were included in this study. Clinical signs of the mice were monitored daily in a double-blinded manner. The mice were sacrificed 23 d after the EAE model was established and the spinal cord tissues were collected. The expression of Serping 1, C3, Srgn and H2-T23 at mRNA level was detected by real-time PCR. Changes in the expression of IL-6, TNF-α, macrophage chemotactic protein-1 (MCP-1) and interferon-inducible protein-10 (IP-10) were measured. Western blot was used to investigate the expression of GFAP and Notch1 in spinal cord tissues and the phosphorylation of signal transduction and transcription activator 3 (STAT3). The expression of Notch1 intracellular domain (NICD) and GFAP in spinal cord tissues was detected by immunofluorescence. Furthermore, the infiltration of inflammatory cells and the demyelination of spinal cord were observed using HE and Luxol fast blue (LFB) staining methods. Results:Compared with PBS group, A1 astrocytes were activated and Notch1 expression was significantly up-regulated in EAE group and LV-ctrl+ EAE group. The clinical score of mice in LV-Inhibit-Gm13568+ EAE group was decreased from an average score of 3.5 to less than 1 on 23 d after antigen induction and the clinical symptoms were alleviated as compared with the mice in LV-ctrl+ EAE group. Meanwhile, the activation of A1 astrocytes was down-regulated, and the production of inflammatory cytokines and chemokines was also reduced. The expression of Notch1, GFAP and NICD at protein level and the phosphorylation of STAT3 were significantly reduced. Moreover, the infiltration of inflammatory cells and demyelination of spinal cord tissues were alleviated significantly.Conclusions:LncRNA Gm13568 might regulate the activation of A1 astrocytes via the Notch1/STAT3 pathway, thus affecting the production of inflammatory cytokines and chemokines and participating in the process of EAE.
ABSTRACT
OBJECTIVE@#To investigate the underlying molecular mechanisms by which silence information regulator (SIRT) 2 and glutaminase (GLS) in the amygdala regulate social behaviors in autistic rats.@*METHODS@#Rat models of autism were established by maternal sodium valproic acid (VPA) exposure in wild-type rats and SIRT2-knockout ( SIRT2 -/-) rats. Glutamate (Glu) content, brain weight, and expression levels of SIRT2, GLS proteins and apoptosis-associated proteins in rat amygdala at different developmental stages were examined, and the social behaviors of VPA rats were assessed by a three-chamber test. Then, lentiviral overexpression or interference vectors of GLS were injected into the amygdala of VPA rats. Brain weight, Glu content and expression level of GLS protein were measured, and the social behaviors assessed.@*RESULTS@#Brain weight, amygdala Glu content and the levels of SIRT2, GLS protein and pro-apoptotic protein caspase-3 in the amygdala were increased in VPA rats, while the level of anti-apoptotic protein Bcl-2 was decreased (all P<0.01). Compared with the wild-type rats, SIRT2 -/- rats displayed decreased expression of SIRT2 and GLS proteins in the amygdala, reduced Glu content, and improved social dysfunction (all P<0.01). Overexpression of GLS increased brain weight and Glu content, and aggravated social dysfunction in VPA rats (all P<0.01). Knockdown of GLS decreased brain weight and Glu content, and improved social dysfunction in VPA rats (all P<0.01).@*CONCLUSIONS@#The glutamate circulatory system in the amygdala of VPA induced autistic rats is abnormal. This is associated with the upregulation of SIRT2 expression and its induced increase of GLS production; knocking out SIRT2 gene or inhibiting the expression of GLS is helpful in maintaining the balanced glutamate cycle and in improving the social behavior disorder of rats.

Objective:To investigate the regulatory effects of sphingosine kinase-2 (SphK2) on the function of activated astrocytes and the progression of experimental autoimmune encephalomyelitis (EAE) in mice.Methods:Primary mouse astrocytes were isolated from wild-type (WT) C57BL/6 mice and sphk2 gene knock-out ( sphk2 -/-) mice and stimulated in vitro with interleukin 17 (IL-17). Real-time PCR was used to measure the expression of inflammatory cytokines and chemokines at mRNA levels. Western blot and immunofluorescence were used to detect the expression of glial fibrillary acidic protein (GFAP) and the phosphorylation of signal transducer and activator of transcription 3 (p-STAT3). An EAE mouse model was constructed using myelin oligodendrocyte glycoprotein 35-55 (MOG 35-55) polypeptide. Western blot was used to detect the expression of GFAP and p-STAT3 at protein level and real-time PCR was used to detect the expression of inflammatory cytokines and chemokines at mRNA level in spinal cords. Hematoxylin-Eosin (HE) and Luxol fast blue (LFB) staining were used to observe the changes in inflammatory cell infiltration and demyelination in spinal cords. Results:Compared with the WT group, the phosphorylation of STAT3 was obviously reduced in in vitro activated mouse astrocytes of sphk2 -/- mice, and the expression of inflammatory cytokines and chemokines including monocyte chemotactic protein 1 (MCP-1), TNF-α and IL-6 at mRNA level was also significantly decreased. Compared with the WT EAE group, changes in the above-mentioned cytokines and relative proteins in sphk2 -/- EAE mice in vivo were similar to those in vitro. Moreover, inflammatory cell infiltration and demyelination were significantly reduced in spinal cords of sphk2 -/- EAE mice. However, no significant difference in in vitro or in vivo GFAP expression was observed between WT and sphk2 -/- mice. Conclusions:SphK2 might regulate the function of reactive astrocytes through STAT3 molecular pathway, thereby regulating the production of inflammatory cytokines and chemokines and participating in the pathological process of EAE.

ABSTRACT
Objective:To evaluate the teaching effect of moral education materials implied in scientific research cases in the teaching of "Experimental Traditional Chinese Medicine (TCM)".Methods:The moral education materials implied in scientific research cases of "Experimental TCM" were extracted and skillfully integrated into the teaching of professional knowledge. A questionnaire survey was conducted with questions as "whether it is good to demonstrate the potential humanistic spirit by case teaching, whether this helps improve your interest in science and whether this teaching form affects your study, life and work attitude in the future" "Ten specific items from scientists' moving deeds that touch students and their recognitions" to assess the teaching effect.Results:95.8 percent of students affirmed this teaching form and thought it helped improve their interest in scientific exploration. 87.5 percent of students considered the humanistic spirit would affect their study, life and work in the future. 77.1-89.6 percent of students held a positive attitude to the ten items derived from the scientists' moving stories. Among these items, the percentages of the two items, "the spirit of being able to endure loneliness, work hard to make contributions selflessly without seeking for rewards or reputations" and "having respect forpeople and their scientific research achievements with courage to challenge the authorities of scientific research" are the lowest and highest, respectively.Conclusion:It is good to apply the moral education materials implied in the scientific research cases in the teaching of "Experimental TCM", which basically achieves the teaching goal, but there is still room for improvement.
ABSTRACT
Experimental Traditional Chinese Medicine is an emerging discipline that plays an important role in cultivating innovative talents of traditional Chinese medicine (TCM). In recent years, with the rapid development of TCM and the new requirements of positioning, and also combined with the college students' cognitive characteristics, we have revised and republished the "Experimental TCM" (Third Edition) textbook, which focuses on introducing knowledge by adopting relevant scientific research cases. This test book was used in the teaching of undergraduates of batch 2013 in the eight-year program in Shanghai University of Traditional Chinese Medicine. After-class questionnaires showed that this teaching mode, guided by scientific research case, is not only helpful for students to develop their quality and ability of adopting modern experimental methods initially in the study and development of TCM, but also able to spread the great achievements of TCM researches. The teaching mode is also conducive to enhancing students' sense of responsibility for the modernization of TCM. Therefore, it is suggested that the course of Experimental TCM should be promoted in the colleges and universities of TCM.
ABSTRACT
Objective:To explore the association between vitamin A, E and recurrent respiratory tract infections (RRTIs) in children.Methods:1 853 children with RRTIs and 2 695 health children were separately selected as cases and controls. Propensity score matching (PSM) analysis were conducted to reducing confounding bias between groups. Blood samples were collected to measure serum levels of vitamins A and E by high performance liquid chromatographie (HPLC). Paired logistic regression was used to determine odds ratios ( OR) and 95% confidence intervals ( CI) to evaluate the association of RRTIs with the serum levels of vitamin A and E. Results:After propensity score estimation and 1∶1 matching, the study cohort included 1 507 cases with RRTIs and 1 507 health children as controls. The main characteristics between the two groups were all not significantly different after matching ( P>0.05). The average levels of vitamin A in two groups were different ( P<0.05). Paired logistic regression analysis showed that greater serum levels of vitamin A had a lower risk of RRTIs ( OR=0.46, 95% CI: 0.22-0.98), similarly, deficiency of vitamin A would also increase the risk of RRTIs ( OR=1.18, 95% CI: 1.00-1.38). The statistical difference was not found between VitE and RRTIs ( P>0.05). Conclusions:The serum levels of vitamin E didn′t have a statistically significant association with RRTIs. However, we observed an obvious association between vitamin A and RRTIs. Hence vitamin A clinical monitoring and supplementation are vital for preventing and treating RRTIs.

ABSTRACT
"If slight diarrhoea, replacing Ephedra with Daphninae"under the article 40 of Treatise on Febrile Diseasesis is controversial. There are two different opions in all physicians, one explaination it is in line with Zhang Zhongjing but without the evidence about"replacing Ephedra with Daphninae"; the other is that Daphninae is too strong to apply in diarrhoea. According to the analysis on Treatise on Febrile and Miscellaneous Diseases, the slight diarrhoea is the phenomenon of Vital qi exorcism. The reason why replacing Ephedra owing to exogenous evil disappearance, the construction of Daphninae Pinellia ternate and Paeony is to expell the water on the leaving way. And we draw a conclusion that the function of Paeony in Xiaoqinglong decoction is inclined to be expelling Water Qi.

ABSTRACT
Objective Intrauterine growth retardation (IUGR) is characterized by low birth weight of neonates. The aim of this study was to provide a reference for the establishment of IUGR models in scientific research, by comparing the experimental data of different rat models of IUGR established by three commonly-used methods. Methods A total of 20 pregnant rats on the day 0 of gestation were divided into 4 groups, with 5 rats in each group (n=5). Among them, 3 groups of rats were treated with alcohol intervention (group A), uterine artery ligation (group U), and low protein diet (LP group), respectively, to establish rat models of IUGR, and the fourth group served as the normal control group (CON group). Fetal rats were taken through cesarean section on the 20th day of gestation. The body mass, brain mass, placental mass, two-kidney mass, body length and tail length of the fetal rats were measured, and the incidence rate of IUGR, stillbirth rate and their brain to placenta ratio were calculated. The fetal rats in each group were continuously raised and the body mass, perirenal fat pad mass and some organ masses were determined at the 3rd, 6th and 12th weeks. Results The average body mass of the fetal rats in the groups A, U and LP group was significantly lower than that of the normal control group (P< 0. 05), and the incidence rate of IUGR of the fetal rats was significantly higher than that of the normal control group (P< 0. 05). In addition, the stillbirth rate of pregnant rats in the group U was significantly higher than those of the group A and LP group (P < 0. 05). After raising the rats for 3 weeks, the average body mass of rats in the three experimental groups was significantly lower than that of the normal control group (P < 0. 05), and after raising for 6 weeks, the average body mass in the three experimental groups was still lower than that of the normal control group, but with a non-significant difference (P> 0. 05). However, after raising for 12 weeks, the average body mass of the rats in the group A and LP group was significantly higher than that of the normal control group (P < 0. 05). Conclusions Rat models of IUGR can be successfully established either by alcohol intervention, uterine artery ligation or low protein diet. The IUGR model established by low protein diet has the advantages of a higher incidence rate of IUGR and lower stillbirth rate, being more suitable for animal model research. As regards the catch-up growth, the average body mass of the rats during the postpartum period and lactation period after delivered by cesarean section in the group A and LP group is lower than that of the normal control group, but after lactation the rats grow faster than those in the normal control group, indicating the existence of a catch-up growth in the group A and LP group.
