ObjectiveTo investigate the effect of myosin heavy chain 7 gene-derived miRNA-208b-3p on the fibrotic phenotype of cardiac fibroblasts. MethodsmiRNA chip array was performed to detect the dysregulated miRNAs in the myocardium of diabetic db/db mice and db/m control mice. Neonatal mouse ventricular cardiomyocytes (NMVCs) and cardiac fibroblasts (CFs) were isolated from C57BL/6 mice and cultured. Real-time quantitative PCR (RT-qPCR) was conducted to determine the expression of miR-208b-3p in mouse CFs and NMVCs subjected to angiotensinⅡ(AngⅡ) and high glucose plus glucose oxidase (G/Go) treatment, respectively. Cell counting kit 8(CCk8) assay, flow cytometry and determination of fibrosis-related protein, including COL1A1, COL3A1and α-SMA, were performed in mCFs transfected with miR-208b-3p. Dual luciferase reporter assay was performed to confirm the interaction between miR-208b-3p and the 3'-UTR of metal response element binding transcription factor 2 (Mtf2) and progesterone receptor membrane component 1(Pgrmc1), respectively. The expressions of Mtf2 and Pgrmc1 at the mRNA and protein levels in mCFs after miR-208b-3p mimic transfection were determined using RT-qPCR and Western blot assay, respectively. The small interfering RNA (siRNA) was used to inhibit Mtf2 and Pgrmc1 expression in mCFs, and the effects of Mtf2 siRNA, Pgrmc1 siRNA and miR-208b-3p on fibrosis-related protein expression in mCFs were investigated. ResultsResults of miRNA chip array and RT-qPCR assay showed that miR-208b-3p was up-regulated in the myocardium of the diabetic db/db mice. miR-208b precursor and the host gene of Myh7 were consistently increased in db/db mice. miR-208b-3p and Myh7 mRNA were expressed in mCFs and NMVCs, but the levels of miR-208b-3p and Myh7 mRNA in NMVCs were much higher than those in mCFs. miR-208b-3p was up-regulated in mCFs and NMVCs subjected to Ang Ⅱ and G/Go treatment, respectively. miR-208b-3p could significantly enhance fibrosis-related protein, including COL1A1, COL3A1 and α-SMA, in mCFs, without affecting the proliferation activity and cell cycle distribution of mCFs. Dual luciferase reporter assay revealed the interactions of miR-208b-3p with the 3'-UTR of Mtf2 and Pgrmc1. The results of RT-qPCR and Western blotting confirmed that miR-208b-3p inhibited Mtf2 and Pgrmc1 expression at the post- transcriptional level. Transfection with miR-208b-3p mimic, Mtf2 siRNA and Pgrmc1 siRNA could consistently enhance the fibrosis-related protein expression in the cardiac fibroblasts. ConclusionsmiR-208b-3p enhances fibrosis-related gene expression by targeting Mtf2 and Pgrmc1in mCFs.

Objective: To explore the short-term efficacy and safety of dapagliflozin in children with hereditary proteinuric kidney disease. Methods: This was a prospective cohort study. From August 2020 to December 2021, 23 children with hereditary kidney disease from Children's Hospital of Fudan University were enrolled. Patients received dapagliflozin 5 mg/d (weight≤30 kg) or initial dose 5 mg/d for 1 week, then 10 mg/d (weight>30 kg) and the dose of angiotensin converting enzyme inhibitors was stable during treatment. Clinical data including demographic parameters, primary diagnosis, estimated glomerular filtration rate (eGFR), 24 h proteinuria and characteristics in the follow-up were collected. The primary outcome was the change in 24 h proteinuria at 12 (±2) weeks, secondary outcomes included changes of 24 h proteinuria at 24 (±2) weeks, eGFR at both 12 (±2) and 24 (±2) weeks. The data were analysed by using mixed linear model. Results: Totally 23 patients were enrolled, including 16 males and 7 females. The age was (10.8±2.9) years. The primary diseases were Alport syndrome (12 cases), Dent disease (5 cases), proteinuria (4 cases), and focal segmental glomerulosclerosis (2 cases) respectively. Primary outcome showed that 24 h proteinuria decreased from baseline at 12 (±2) weeks during treatment (1.75 (1.46, 2.20) vs. 1.84 (1.14, 2.54) g/m2, P<0.05). Secondary outcomes showed that there was no significant difference in 24 h urine protein at 24 (±2) weeks (P>0.05). eGFR decreased slightly at 12 (±2) weeks ((107±21) vs. (112±28) ml/(min·1.73m2), P<0.05), and there was no significant difference at 24 (±2) weeks (P>0.05). Serum albumin increased at 12 (±2) and 24 (±2) weeks following the treatment ((39±8) vs. (37±8) g/L, (38±7) vs. (37±8) g/L, both P<0.05). No hypoglycemia event was reported during the treatment. Conclusion: The dapagliflozin had therapeutic effects on decreasing proteinuria and increasing serum albumin in short-term treatment in children with hereditary proteinuric kidney disease, no hypoglycemia or serious adverse events were observed.

Objective: To analyze the impact of metabolic risk factors on the epidemiological characteristics of the reactivation of inactive HBsAg carriers (IHC) and provide effective intervention measures to standardize the management of chronic hepatitis B infections. Methods: Based on the chronic hepatitis B infection cohort established in 2010 in Jiangsu province, six follow-up visits from 2012 to 2020 were conducted to analyze the characteristics and influencing factors of the hepatitis B reactivation of IHC and the impact of metabolic risk factors, including obesity, high blood pressure, diabetes and hyperglycemia. Results: From 2012 to 2020, 2 527 IHC and 17 730 person-years were observed during a median follow-up period of 7.0 person-years. Ninety-eight cases of hepatitis B reactivation, with a cumulative reaction rate, was 3.9%, and the incidence density was 5.53/1 000 person-years. Multivariate Cox proportional risk regression analysis showed that age and baseline HBV DNA were independent risk factors of HBV reactivation. Compared with the patients ≥60 years, 40-49 age group (aHR=2.16, 95%CI:1.20-3.90) and 20-29 age group (aHR=5.48, 95%CI:2.07-14.48) were significantly associated with hepatitis B reactivation. Compared with the HBV DNA negative patients at baseline, the risk of hepatitis B reactivation was higher in the group with low HBV DNA level 100-1 999 IU/ml (aHR=1.67, 95%CI:1.11-2.52). Stratification analysis results showed that compared with those without metabolic risk factors, in the ≥50 age group, patients with ≥2 metabolic risk factors showed adjusted HR of 2.73 (95%CI:1.08-6.96). Conclusions: The risk of hepatitis B being reactive is the persistent existence of IHC in communities in Jiangsu province, especially young adults, low-level HBV DNA carriers, and IHC with ≥2 metabolic risk factors. Follow-up for these IHC should be strengthened to reduce the risk of disease progression by antiviral treatment at the right time.

Objective: To investigate the expression of VISTA and PD-L1 in triple-negative breast cancer (TNBC) and to explore its relationship with clinicopathologic features and prognosis. Methods: Ninety TNBC patients who underwent surgical resections between 2016 to 2018 in Jiangsu Province Hospital were selected. The expression of VISTA and PD-L1 in both tumor cells and immune cells was evaluated by immunohistochemistry, and the relationship with clinicopathologic parameters and prognosis was analyzed. Results: VISTA was expressed in 17.8% (16/90) of the tumors. The expression of VISTA in tumor cells was related to a higher Ki-67 proliferation index (P=0.02) and higher number of tumor-infiltrating lymphocytes (TIL, P<0.01). VISTA was expressed in 71.1% (64/90) of the immune cells and the expression correlated with smaller tumor size (P=0.02), lower T stage (P=0.04), higher number of TIL (P<0.01), higher number of CD8+T cells (P=0.03) and higher Ki-67 proliferation index (P=0.02). PD-L1 was expressed in 17.8% (16/90) of the immune cells and the expression correlated with higher histologic grade (P=0.04), higher Ki-67 proliferation index (P=0.02) and higher number of TIL (P<0.01). VISTA expression was higher in immune cells within TNBC patients than PD-L1 (P<0.01). Among 90 TNBC patients, complete follow-up was obtained in 85 patients, 8 of whom had recurrences or metastasis after surgery, and two patients cases died of recurrences or metastasis. Conclusions: The expression rate of VISTA is higher than that of PD-L1 in TNBC. The expression of VISTA in immune cells predicts a lower T stage. VISTA may act as an effective immunotherapy target.

The main purpose of the National Nutrition and Health Systematic Survey for children 0-17 years of age in China (CNHSC) was to collect basic data on the nutrition, development, and health status for children in different regions across China using evidence-based, reliable, and cost-effective approaches. Children and their parents or guardians from seven regions (south, southwest, north, northwest, eastern, central, and northeast China) in China were recruited. A multi-stage stratified randomized sampling method was used. Two provinces were randomly sampled from each of the seven regions, from which one urban district and one rural country were also randomly sampled, resulting in a total of 28 survey counties/districts. Dietary surveys, health examinations, laboratory testing, and questionnaires were used to collect dietary intake, nutritional status, child development, and health status information. Nutrition, health, and lifestyle assessment of children and their parents was determined using the Knowledge Attitude Practice (KAP) survey. Greater than 100,000 children (38,000 children < 6 years of age and 66,000 children 6-17 years of age) completed the survey. The survey provided comprehensive data on child nutrition and health status for future studies and will serve as the basis for an integrated nutrition and health improvement strategies proposal for children in China.

Objective:To report two cases of post-transplantation lymphoproliferative disorders (PTLD) after kidney transplantation in children and review the literature, and to improve clinicians' understanding of PTLD in children.Methods:The clinical data of two children with PTLD admitted to the Children's Hospital of Fudan University were collected and analyzed. The PTLD-related literature of PubMed, Embase, Web of Science, Scopus, Cochrane Library, Wanfang, CNKI, Weipu Database and China Biomedical Literature Service System from the establishment of the database to January 2020 were collected for literature review. Multivariate logistic regression analysis method was used to analyze the influencing factors of prognostic in children with PTLD.Results:Both of the patients had negative Epstein-Barr virus (EBV) and Cytomegalovirus (CMV) before transplantation and anti-thymocyte immunoglobulin (ATG) were induced during transplantation. PTLD in case 1 and case 2 was diagnosed at 3 and 12 months after transplantation, respectively, with positive EBV and CMV serological reaction. The pathological diagnosis was monomorphic PTLD in case 1 and the case 2 was clinically considered as non-hodgkin lymphoma. They all received thrapies of immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. PTLD was relieved and graft function was normal in 2 cases, while case 1 died two and half years after transplantation due to intracranial fungal infection. According to the analysis of 56 children (including 2 cases in this study) with PTLD from the literature review, the median time of PTLD from transplantation was 41.8 months. The initial involved organs were digestive tract [17 cases (30.4%)], respiratory system [8 cases (14.3%)], nervous system [7 cases (12.5%)] and pharyngeal lymph ring [7 cases (12.5%)], respectively. The main pathologic type of PTLD was monomorphic [34 cases (60.8%)]. Fifty-six cases were all positive in EBV serological reaction when PTLD was diagnosed. The treatment included immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. Forty-eight cases of PTLD were relieved, while 8 cases lost graft function. Eleven cases died, including 3 cases due to infection and the other 8 cases due to PTLD. Multivariate logistic regression showed that monomorphic PTLD was a risk factor of death for PTLD children ( OR=21.616, 95% CI 1.007-464.107, P=0.049). Conclusions:PTLD in children with kidney transplantation is mostly associated with EBV infection, and the clinical manifestations are diverse. Monomorphic PTLD has a poor prognosis and high mortality.

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

BACKGROUND:
Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China.
METHODS:
The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD.
RESULTS:
A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05).
CONCLUSION
Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.
