Post-traumatic stress disorder (PTSD) is a relatively common but complex mental illness with a range of diverse risk factors. Typical symptoms include the re-experience or avoidance of traumatic events, cognitive impairment, and hypervigilance. While the exact pathogenesis of PTSD is unclear, many studies indicate that epigenetic regulation plays a key role in its development. Specifically, numerous studies have indicated that the levels of histone acetylation and methylation, DNA methylation, and noncoding RNA are altered in PTSD patients. Further to this, natural products have been found to achieve epigenetic regulation of PTSD by regulating the expression of epigenetic enzymes, long noncoding RNA (lncRNA), and miRNA, thereby playing a role in improving PTSD symptoms. To date, however, no epigenetic regulation related drugs have been used in the treatment of PTSD. Furthermore, while natural products that can epigenetically regulate PTSD have received increasing levels of attention, there have not yet been any systematic reports on the topic. Here, we summarized the roles and mechanisms of natural products in the epigenetic regulation of PTSD, providing a novel and unique perspective that will help to guide the development and application of new PTSD treatments.

ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

OBJECTIVE To explore the changes of microribonucleic acid(miR)-223,miR-155 and miR-125 in the neonates with sepsis and analyze the distribution of pathogens so as to provide bases for clinical diagnosis and treatment of neonates with sepsis.METHODS A total of 39 neonates with sepsis who were treated in Jinan Second Maternal and Child Health Hospital from May 2021 to May 2023 were enrolled in the study and were assigned as the study group,meanwhile,42 healthy neonates who were born in the hospital were chosen as the control group.The distribution and drug resistance of the pathogens isolated from the neonates of the study group were statistically analyzed.The relative expression levels of peripheral blood miR-223,miR-155 and miR-125 were com-pared between the two groups,and the values of the three indexes in diagnosis of neonatal sepsis were analyzed.RESULTS Totally 46 strains of pathogens were isolated from the 39 neonates with sepsis,20 of which were Escherichia coli,and 10 were Staphylococcus aureus.The E.coli strains were resistant to ampicillin,tetra-cycline,ciprofloxacin and cefazolin;the S.aureus strains were resistant to penicillin,erythromycin,cefazolin and clindamycin,with the drug resistance rates higher than 50％.The expression level of miR-223 of the study group was 2.13±0.70,higher than that of the control group,the expression level of miR-125 of the study group was 0.92±0.30,higher than that of the control group;while the expression level of miR-155 of the study group was 2.08±0.68,lower than that of the control group(P＜0.05).The area under the curve(AUC)of the joint detec-tion of miR-223,miR-155 and miR-125 was 0.945 in diagnosis of neonatal sepsis,with the sensitivity 92.31％,the specificity 88.10％.CONCLUSIONS E.coli and S.aureus are dominant among the pathogens isolated from the neonates with sepsis.The neonates with sepsis show abnormal expressions of peripheral blood miR-223,miR-155 and miR-125,and the joint detection of the three indexes has high value in diagnosis of neonatal sepsis.

Objective:To investigate the status quo of intravenous (IV) infusion device selection among hospitalized children and provide direction for improving practices related to the selection of infusion devices.Methods:A total of 1 306 hospitalized children undergoing IV infusion treatment in 11 clinical departments of Children's Hospital of Fudan University in June 2021 were selected by convenience sampling. A self-developed data collection form for the selection of IV infusion devices in hospitalized children and criteria for the appropriateness of IV infusion device selection were used to survey and evaluate the appropriateness of IV infusion device selection among these children.Results:IV infusion devices were found to have been appropriately selected in 1 137 of the 1 306 children, while these devices were inappropriately selected in 169 children. The inappropriate selection was primarily due to the improper choice of peripheral intravenous catheters (PIVC), with 155 cases involving the administration of non-peripheral compatible medications through PIVC. No significant statistical difference was found in the appropriateness of IV infusion device selection between the infant group and the child and adolescent group ( P>0.05). Significant differences were observed in the appropriateness of IV infusion device selection based on different physicochemical properties of medications and the duration of therapy ( P<0.01) . Conclusions:The standardization of IV infusion device selection among hospitalized children needs improvement. It is urgent to apply evidence from the Clinical Practice Evidence- Based Guidelines for Pediatric Intravenous Therapy regarding recommendations for IV infusion device selection, to initiate evidence application projects, and to standardize the selection of IV infusion devices.

Objective To analyze the characteristics of conventional ultrasound and contrast-enhanced ultrasound(CEUS)in hypovascular renal tumors,and to explore the application value of combining the 2 methods in diagnosing benign and malignant hypovascular renal tumors.Methods The conventional ultrasound and CEUS data of 104 hypovascular renal tumors(76 benign lesions[benign group]and 28 malignant lesions[malignant group])from 99 patients,who were confirmed by postoperative pathology,biopsy pathology or computed tomography(CT)/magnetic resonance imaging(MRI)enhancement combined with long-term follow-up in Ruijin Hospital,Shanghai Jiao Tong University School of Medicine and its Wuxi Branch from Oct.13,2009 to Oct.26,2022,were retrospectively analyzed.The location,size,internal echo,morphology,internal and peripheral blood supply of the lesions were observed by conventional ultrasound,and the perfusion mode,regression pattern,perfusion uniformity and ring enhancement signs were observed by CEUS.Taking the pathological results or confirmed results of CT/MRI enhancement combined with long-term follow-up as the gold standard,the value of conventional ultrasound combined with CEUS in the differential diagnosis of benign and malignant hypovascular renal tumors was analyzed.Results There were significant differences in gender,age of patients and internal echo,contrast agent regression and ring enhancement signs of lesions between the 2 groups(all P＜0.05).The malignant tumors were mostly found in males(78.6％,22/28)with an average age of(58.29±11.76)years old;the masses were mostly hypoechoic(64.3％,18/28),and rapid washout was predominant with CEUS(60.7％,17/28).In the benign group,most of the patients were female(55.3％,42/76),with an average age of(50.64±14.88)years old;the majority of the masses were hyperechoic(64.5％,49/76),and CEUS showed simultaneous washout as the main lesion(56.6％,43/76).Three patients(10.7％,3/28)with ring enhancement signs were all malignant.The diagnostic accuracy(82.7％)and specificity(88.2％)for benign and malignant hypovascular renal tumors were relatively high when combining the diagnostic indicators of ring enhancement signs and hypoechoic.The diagnostic sensitivity(85.7％)and negative predictive value(92.3％)were relatively high when combining the 3 diagnostic indicators of ring enhancement,hypoechoic,and rapid washout.Conclusion Conventional ultrasound combined with CEUS has significant clinical practical value in the differential diagnosis of benign and malignant hypovascular renal tumors.The ring enhancement sign is highly specific in the diagnosis of malignant hypovascular renal tumors.However,if this sign is not significant and conventional ultrasound shows hypoechoic or CEUS exhibits rapid washout,there is a strong suggestion that the mass may be a malignant lesion.

ObjectiveTo compare the differences in intestinal absorption of nanophase（NP） formed by single decoction and combined decoction of Ginseng Radix et Rhizoma（GRR） and Zingiberis Rhizoma Recens（ZRR） in rats， and to investigate the effects of new NP formed by the combined decoction on the absorption of main components in GRR and ZRR. MethodDifferential centrifugation and dialysis techniques were used to enrich NP in the single and combined decoctions of GRR and ZRR， respectively. The microstructure， particle size， Zeta potential and concentration of the NP were analyzed by transmission electron microscope， particle size analyzer and nanoparticle tracking analyzer. Based on everted gut sac model， the index components in the intestinal absorption solution of NP from the single and combined decoctions were analyzed by ultra-performance liquid chromatography-triple quadrupole tandem mass spectrometry（UPLC-QqQ-MS/MS）. The per unit area actual value of cumulative intestinal absorption（Q_actual）， absorption rate constant（K_a） and apparent permeability coefficient（P_app） were used as the evaluating indexes to investigate the absorption characteristics of the aforementioned NP in the duodenum， jejunum， ileum and colon. ResultIrregularly spherical NP was present in the single and combined decoctions， and the contents of components in NP of the combined decoction were mostly lower than those in the single decoction. In these NP， ten components could be absorbed into the intestinal sac， with the main absorption site being the small intestine， and the P_app was greater than 1×10^-5 cm·min^-1. Compared with NP in the single decoction， the Q_actual and K_a of ginsenoside Rb₁， ginsenoside Rf， 4-gingerol and 6-shogaol were significantly increased in NP of the combined decoction， while ginsenoside Re and 6-gingerol were significantly decreased（P<0.01）. Except for ginsenoside Re and ginsenoside Rd， the P_app of the remaining constituents was significantly increased in NP of the combined decoction（P<0.01）. In addition， the maximum intestinal segment site of Q_actual was shifted forward for ginsenoside Rb₁， ginsenoside Rd and ginsenoside Ro， while shifted backward for ginsenoside Rg₁， ginsenoside Re and 8-gingerol. The maximal intestinal segment sites of K_a and P_app of ginsenoside Rb₁， ginsenoside Rg₁， ginsenoside Rd and ginsenoside Ro shifted forward， while ginsenoside Re and 4-gingerol were shifted backward. ConclusionThe combined decoction of GRR and ZRR is helpful to promote the absorption of the effective components of the two， and changes the absorption behavior of the effective components in some intestinal segments. This study provides a reference for the subsequent research on the compatibility mechanism of the two medicines.

Objective:To evaluate the effect of autologous hematopoietic stem cell transplantation (ASCT) on the treatment of relapsed/refractory multiple myeloma (RRMM) with chimeric antigen receptor T cell (CAR-T) therapy.Methods:A retrospective cohort study. The clinical data of 168 patients with RRMM who underwent CAR-T therapy at the Department of Hematology, Xuzhou Medical University Hospital from 3 January 2020 to 13 September 2022 were analyzed. Patients were classified into a transplantation group (TG; n=47) and non-transplantation group (NTG; n=121) based on whether or not they had undergone ASCT previously. The objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and the levels of CD3, CD4, CD8, CD19, CD56 and natural killer (NK) cells before CAR-T infusion were analyzed by χ2 test, Kaplan-Meier method and independent sample t-test. Results:Among 168 patients with RRMM, 98 (58.3%) were male. The median age of onset was 57 (range 30-70) years. After CAR-T therapy, the ORR of patients was 89.3% (92/103) in the NTG and 72.9% (27/73) in the TG. The ORR of the NTG was better than that of the TG ( χ2=5.71, P=0.017). After 1 year of CAR-T therapy, the ORR of the NTG was 78.1% (75/96), and that of the TG was 59.4% (19/32). The ORR of the NTG was better than that of the TG ( χ2=4.32, P=0.038). The median OS and PFS in the NTG were significantly longer than those in the TG (OS, 30 vs. 20 months; PFS, 26 vs. 12 months; both P<0.05). The CD4 level before CAR-T infusion in the TG was significantly lower than that in the NTG (25.65±13.56 vs. 32.64±17.21; t=-2.15, P=0.034), and there were no significant differences in the counts of CD3, CD8, CD19, CD56, and NK cells between the TG and NTG (all P>0.05). Conclusion:Among patients suffering from RRMM who received CAR-T therapy, patients who did not receive ASCT had significantly better outcomes than those who had received ASCT previously, which may have been related to the CD4 level before receiving CAR-T therapy.

Objective:This study aimed to investigate the effect of lipohypertrophy induced by insulin injection on blood glucose fluctuation in patients with type 1 diabetes mellitus.Methods:A total of 80 patients with type 1 diabetes mellitus were recruited between June 2021 and December 2021 from the First Affiliated Hospital of Nanjing Medical University. And these patients all received insulin injection more than six months. Lipohypertrophy was assessed by ultrasound scanning, and blood glucose fluctuation was evaluated using the flash glucose monitoring system(FGM). Univariate analysis and multivariate linear regression were used to analyze the relationship of lipohypertrophy and and core indicators of blood glucose fluctuation.Results:Compared with patients without lipohypertrophy, patients with lipohypertrophy had higher mean amplitude of glycemic excursions(MAGE), coefficient of variation(CV), mean of daily differences(MODD), standard deviation(SD) of blood glucose, time above range(TAR), and high blood glucose index(HBGI; all P<0.05), while time in range(TIR) of glucose markedly become lower( P<0.01). Moreover, multivariate linear regression analysis showed that lipohypertrophy detected by ultrasound was an independent influencing factor of TIR( β=-9.423, P=0.032), MAGE( β=1.114, P=0.039), CV( β=4.304, P=0.041), MODD( β=0.717, P=0.046) after adjusting for age at diagnosis, duration of insulin injection, fasting C-peptide, and daily dose of insulin per unit weight. Conclusion:Lipohypertrophy increases glycemic variability and imposes negative impact on glycemic control rate in patients type 1 diabetes mellitus.

Objective:To investigate the ego-depletion level of adolescents with type 1 diabetes mellitus (T1DM) and to explore its association with glycemic control and quality of life.Methods:This was a cross-sectional survey study. A total of 195 adolescents with T1DM were recruited from the First Affiliated Hospital of Nanjing Medical University from March to September 2022 by convenient sampling method. The Self-Regulatory Fatigue Scale (SRF-S) and Short Form of the Chinese version Diabetes Quality of Life for Youth Scale (C-DQOLY-SF) and the general information questionnaire were collected and the glycated hemoglobin (HbA 1c) value was detected. Results:The total score of self-regulatory fatigue for 195 adolescents with T1DM was (42.23 ± 9.94) points, with a scoring rate of 52.79%, which was at a medium level. Pearson correlation analysis showed that the total score of self-regulatory fatigue was positively correlated with HbA1c ( r = 0.25, P<0.01), and negatively correlated with quality of life ( r = -0.61, P<0.01). The hierarchical linear regression results showed that after controlling for demographic sociolagy and disease variables, ego-depletion had a positive predictive effect on HbA1c ( t = 3.69, P<0.01), while ego-depletion had a negative predictive effect on Quality of life ( t = -8.48, P<0.01). Conclusions:Ego-depletion of adolescents with T1DM may affect their blood glucose control and quality of life, which should be noticed by medical workers.
