Objective To compare the efficacy and safety between hypofractionated radiotherapy(HyRt)and conventional radiotherapy after breast-conserving surgery.Methods This study was a single-center,prospective,randomized controlled study.Eighty-three patients with pTis-T2N0M0 breast cancer admitted to Tangshan People's Hospital from May 2017 to May 2019 were included.The patients received breast-conserving surgery+sentinel lymph node biopsy(SLNB).After surgery,they were treated with intensity modulated radiation therapy(IMRT).According to random table method,patients were divided into HyRt group(n=41)and conventional radiotherapy group(n=42).The dose of organs at risk,treatment efficacy,treatment failure modes,and radiotherapy related adverse reactions were analyzed in the two groups.The radiotherapy-related adverse reactions were evaluated according to NCI CTC AE Version 3.0,including radiation dermatitis,radiation pneumonia,breast/skin fibrosis,pulmonary fibrosis,etc.Results Eighty-three patients with breast cancer were included,with a median age of 44(26-67)years.There was no statistically significant difference in clinical parameters such as age(P=0.443),TNM stage(P=0.335),molecular typing(P=0.333),degree of differentiation(P=0.617),and pathological type(P=0.127)between the two groups of patients.Compared with conventional radiotherapy group,the V5(25.6％vs.33.8％,P=0.015),V20(13.3％vs.17.2％,P=0.042),and the mean radiation dose(MLD;7.4 Gy vs.10.4 Gy,P=0.020)of the affected lung of HyRt group significantly decreased.Only 3 patients in this study experienced distant metastasis,and no regional lymph node metastasis or local recurrence was observed.There was no significant difference in PFS rate at 2 years between HyRt group and conventional radiotherapy group(94.4％vs.85.2％,P=0.818).Compared with conventional radiotherapy group,the incidence of≥grade Ⅱ irradiation dermatitis in HyRt group was significantly reduced(2.4％vs.21.4％,P=0.015).There was no difference in the incidence of grade Ⅰ breast/skin fibrosis(19.5％vs.14.3％,P=0.570)between the two groups,and no grade Ⅲ radiotherapy-related side effects were observed in the two groups.Conclusions Compared with conventional radiotherapy with simultaneously integrated boosting-intensity modulated radiotherapy,the patients who received HyRt after breast-conserving surgery for early-stage breast cancer have good tolerance and low incidence of adverse reactions.HyRt can be used as the first option of radiation therapy.

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.

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.

The paper summarizes the clinical and follow-up data of percutaneous endoscopic gastrostomy (PEG) in three infants with chronic kidney disease to explore the safety and reliability of using PEG to improve the growth and development, and nutritional status. During follow-up, the weight and height of case 1 and 3 were obviously improved. Case 2 was followed up for 3 months, due to dying of cardiac arrest, and the infant's height and weight were not significantly improved. Serum albumin and prealbumin improved in 3 cases after PEG. No PEG-related infection occurred in 3 infants.

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.

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.

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.

During the traumatic brain injury (TBI), improved expression of circulatory miR-21 serves as a diagnostic feature. Low levels of exosome-miR-21 in the brain can effectively improve neuroinflammation and blood-brain barrier (BBB) permeability, reduce nerve apoptosis, restore neural function and ameliorate TBI. We evaluated the role of macrophage derived exosomes-miR-21 (M-Exos-miR-21) in disrupting BBB, deteriorating TBI, and Rg1 interventions. IL-1

Objective:Nivolumab is one of the most common programmed death 1 （PD-1） inhibitors used as an immune checkpoint inhibitor （ICI）. It brings significant therapeutic effects but often accompanied by serious drug toxicity. The pulmonary toxicities of nivolumab are not clear. This study aims to systematically explore the nivolumab-associated pulmonary toxicities and provide reference for clinical treatment. Methods:Data were extracted from US Food and Drug Administration （FDA） Adverse Event Reporting System （FAERS） database from January 1， 2016 to September 30， 2019. Two types of disproportionality analysis， information component （IC） and reporting odds ratio （ROR）， were applied in nivolumab-associated pulmonary adverse events （AEs） signal detection. Results:A total of 28 489 309 records were extracted from FAERS database and 8 181 records were associated with nivolumab. Analysis was conducted in 179 AEs and 86 signals were detected. Notably， potent signals were detected in radiation pneumonitis （IC₀₂₅： 3.99， ROR₀₂₅： 17.25）， pneumonitis （IC₀₂₅： 3.34， ROR₀₂₅： 10.64） and bronchial fistula （IC₀₂₅： 2.94， ROR₀₂₅： 8.78）. Nivolumab-associated pulmonary toxicities were more frequently reported in dyspnoea （IC₀₂₅： 0.50， ROR₀₂₅： 1.44）， pneumonia （IC₀₂₅： 0.08， ROR₀₂₅： 1.07） and pneumonitis （IC₀₂₅： 3.34， ROR₀₂₅： 10.64）. Results of IC and ROR methods were similar to each other. Most pulmonary toxicities were observed in patients with non-small cell lung cancer （N=3 711， 32.13%）， malignant melanoma （N=1 658， 14.36%） and renal cell carcinoma （N=731， 6.33%）. Conclusion:Significant pulmonary toxicities were detected in patients treated with nivolumab. Thus， it is highly important for clinicians to be vigilant about nivolumab-associated pulmonary AEs and be prepared to take immediate action for patient safety.
