		                        			 AIM: To investigate the clinical value of serum vitamin A(Vit A)and basic fibroblast growth factor(bFGF)levels predicting retinopathy of prematurity(ROP).METHODS: Prospective cohort studies. A total of 411 premature or low birth weight infants with gestational age less than 37 wk or birth weight less than 2 500 g who were delivered in Hainan Branch, Shanghai Children's Medical Center Affiliated to Shanghai Jiao Tong University School of Medicine from January 2020 to December 2022 were selected as subjects. The Vit A and bFGF levels in peripheral blood were detected at 7 d and 35 d after birth, respectively.RESULTS: A total of 392 premature infants or low birth weight infants completed clinical study, including 51 cases in stage 1-2 ROP group, 23 cases in stage 3-5 ROP group and 318 cases in the group without ROP. At 7 d postnatal, the serum Vit A(0.44±0.17 μmol/L)and bFGF(0.53±0.16 ng/L)levels in stage 1-2 ROP group were lower than those in the group without ROP(0.50±0.12 μmol/L and 0.63±0.15 ng/L; all P<0.05). The serum Vit A(0.34±0.18 μmol/L)and bFGF(0.44±0.18 ng/L)levels in stage 3-5 ROP group were lower than those in the group without ROP(P<0.05). The serum Vit A and bFGF levels in stage 3-5 ROP group were lower than those in stage 1-2 ROP group(P<0.05). At 35d postnatal, the serum Vit A(0.33±0.19 μmol/L)and bFGF(0.39±0.19 ng/L)levels in stage 3-5 ROP group were lower than those in stage 1-2 ROP group(0.43±0.16 μmol/L and 0.48±0.17 ng/L; all P<0.05). According to the ROC curve drawn by serum Vit A, the AUC value was 0.853, the maximum Youden index was 0.68, the best sensitivity was 73%, and the best specificity was 95%. According to the ROC curve drawn by serum bFGF, the AUC value was 0.828, the maximum Youden index was 0.58, the best sensitivity was 90%, and the best specificity was 68%. According to the ROC curve drawn by serum Vit A combined with bFGF, the AUC value was 0.917, the maximum Youden index was 0.70, the best sensitivity was 70%, and the best specificity was 100%.CONCLUSION: Serum Vit A and bFGF levels are sensitive and effective indicators for predicting ROP. If the serum Vit A or bFGF levels are lower in premature infants or low birth weight infants, it may indicate the higher probability of ROP and its pathological stages. In addition, the clinica value of serum Vit A combined with bFGF in the diagnosis of ROP is higher than that of Vit A or bFGF alone, and the misdiagnosis rate is reduced.

		                        			Cancer genomics has led to the discovery of numerous oncogenes and tumor suppressor genes that play critical roles in cancer development and progression.Oncogenes promote cell growth and proliferation,whereas tumor suppressor genes inhibit cell growth and division.The dysregulation of these genes can lead to the development of cancer.Recent studies have focused on non-coding RNAs(ncRNAs),including circular RNA(circRNA),long non-coding RNA(lncRNA),and microRNA(miRNA),as therapeutic targets for cancer.In this article,we discuss the oncogenes and tumor suppressor genes of ncRNAs associated with different types of cancer and their potential as therapeutic targets.Here,we highlight the mechanisms of action of these genes and their clinical applications in cancer treatment.Understanding the molecular mechanisms underlying cancer development and identifying specific therapeutic targets are essential steps towards the development of effective cancer treatments.

		                        			Background::Hepatic ischemia-reperfusion injury (HIRI) remains a common complication during liver transplantation (LT) in patients. As a key downstream effector of the Hippo pathway, Yes-associated protein (YAP) has been reported to be involved in various physiological and pathological processes. However, it remains elusive whether and how YAP may control autophagy activation during ischemia-reperfusion.Methods::Human liver tissues from patients who had undergone LT were obtained to evaluate the correlation between YAP and autophagy activation. Both an in vitro hepatocyte cell line and in vivo liver-specific YAP knockdown mice were used to establish the hepatic ischemia-reperfusion models to determine the role of YAP in the activation of autophagy and the mechanism of regulation. Results::Autophagy was activated in the post-perfusion liver grafts during LT in patients, and the expression of YAP positively correlated with the autophagic level of hepatocytes. Liver-specific knockdown of YAP inhibited hepatocytes autophagy upon hypoxia-reoxygenation and HIRI ( P <0.05). YAP deficiency aggravated HIRI by promoting the apoptosis of hepatocytes both in the in vitro and in vivo models ( P <0.05). Attenuated HIRI by overexpression of YAP was diminished after the inhibition of autophagy with 3-methyladenine. In addition, inhibiting autophagy activation by YAP knockdown exacerbated mitochondrial damage through increasing reactive oxygen species ( P <0.05). Moreover, the regulation of autophagy by YAP during HIRI was mediated by AP1 (c-Jun) N-terminal kinase (JNK) signaling through binding to the transcriptional enhanced associate domain (TEAD). Conclusions::YAP protects against HIRI by inducing autophagy via JNK signaling that suppresses the apoptosis of hepatocytes. Targeting Hippo (YAP)-JNK-autophagy axis may provide a novel strategy for the prevention and treatment of HIRI.

		                        			Objective:To investigate the clinic opathological features, treatment and prognosis of children newly diagnosed with ependymoma.Methods:Clinical data of 127 pediatric ependymoma (EPN) patients (0-16 years old) treated with tumor resection and postoperative radiotherapy at Xinhua Hospital Affiliated to Shanghai Jiao Tong University between 2001 and 2021 were retrospectively analyzed. Among them, 53 children were female and 74 were male. Local control (LR), event-free survival (EFS) and overall survival (OS) rates were analyzed by Kaplan-Meier method. The relationship between clinic opathological factors and clinical prognosis, and the effect of treatment on clinical prognosis of patients were analyzed by Cox proportional hazards model.Results:At a median follow-up time of 29 months (3-251 months), the 3-year OS and EFS rates were 89.5% and 71.5%, respectively. For patients undergoing incomplete resection followed by postoperative adjuvant radiotherapy, the 3-year LR, OS and EFS rates were 78.3%, 65.8% and 85.7%, respectively. A total of 43 children were aged <3 years old when diagnosed and 84 aged ≥3 years old. The interval time between surgery and radiotherapy in children aged <3 years old was 91 d, and 35.5 d in those aged ≥3 years old ( P<0.001). For patients <3 years old, the median EFS was 90 months when initiating radiotherapy within ≤70 d after surgery, compared to 43 months for those who initiated radiotherapy at >70 d after surgery ( P=0.053). According to fifth edition of the WHO classification of tumors of the central nervous system (WHO CNS5), 39 children were classified as posterior fossa ependymoma group A (PFA group). The OS and EFS rates in the PFA group were significantly less than those in other groups (3-year OS rate were 69.2% vs. 94.6%, P<0.001; 3-year EFS rate were 46.9% vs. 79.1%, P<0.001). In the PFA group, 12 patients received postoperative adjuvant chemotherapy, 14 did not receive chemotherapy, and whether chemotherapy was given was unknown in 13 cases. No significant differences were observed in OS and EFS between patients treated with and without chemotherapy ( P=0.260, P=0.730). Univariate Cox analysis showed that tumor location and WHO CNS5 molecular classification were significantly associated with EFS, and WHO CNS5 molecular classification was significantly correlated with OS. Multivariate Cox analysis showed that tumor location in the posterior fossa was an independent risk factor for EFS ( HR=2.72, 95% CI=1.1~6.71, P=0.03). Conclusions:Patients newly diagnosed with pediatric ependymoma can obtain favorable survival after surgery combined with postoperative adjuvant radiotherapy. Patients with residual tumors can achieve favorable LC and survival after postoperative adjuvant radiotherapy. Delaying of radiotherapy tends to lead to poor survival for patients aged <3 years old when diagnosed. Children in the PFA group obtain worse prognosis compared to their counterparts in other groups. The tumor location in the posterior fossa is an independent risk factor for pediatric ependymoma.

Methods:28 pregnant women with GDM were selected for the study group from May 2020 to December 2021, and 45 pregnant women with normal glucose tolerance were selected for the control group. 25-(OH)D 3, APN, chemerin, islet resistance index (HOMA-IR), fasting blood glucose, fasting insulin, and HbA1c were compared between the two groups. The correlation between 25-(OH)D 3, APN, chemerin, and GDM insulin resistance was analyzed. Results:Fasting blood glucose, fasting insulin, HOMA-IR, and chemerin in the GDM group were higher than those in the control group (all P<0.05), while 25-(OH)D 3 and APN were lower than those in the control group (all P<0.05). There was no statistical difference in HbA1c between the two groups. Logistic regression analysis showed that serum 25-(OH)D 3, APN, and chemerin were all related influencing factors of GDM (all P<0.05). Spearman's correlation analysis showed that serum 25-(OH)D 3 was negatively correlated with fasting blood glucose and HOMA-IR (all P<0.05), chemerin was positively correlated with fasting insulin and HOMA-IR (all P<0.05). ROC curve analysis showed that the AUC of 25-(OH)D 3 was 0.841 (95% CI: 0.746~0.967). AUC of APN was 0.678 (95% CI: 0.545~0.812). AUC of chemerin AUC was 0.360 (95% CI: 0.233~0.487). Conclusions:The levels of 25-(OH)D 3, APN, and chemerin have a certain correlation with the pathogenesis of GDM, which has a certain reference value for the prediction of GDM.

The General Information Questionnaire, the Medication Knowledge and Medication Belief Questionnaire, and the Chinese version of the 8-item Morisky Medication Adherence Scale (MMAS-8) were used to investigate the elderly. A total of 600 questionnaires were distributed, 510 valid questionnaires were recovered, and the valid recovery rate was 85.0%.Results:Among the 510 elderly patients with polypharmacy in the community, 191 elderly patients (37.5%) had good adherence, 187 elderly patients (36.7%) had moderate adherence, and 132 elderly patients (25.9%) had poor adherence. The results of univariate analysis showed that there were statistical differences in age, gender, educational level, family monthly income, type of medication, medication belief and medication knowledge ( P<0.05) . Logistic regression analysis showed that educational level, medication knowledge, and medication belief were the independent influencing factors of medication adherence among the elderly with polypharmacy, and the difference was statistical difference ( P<0.05) . Conclusions:Medication adherence among the elderly with polypharmacy in the community of Hangzhou is poor, and medication knowledge and medication belief need to be improved. Medical and nursing staff should strengthen medication guidance, and use comprehensive interventions to conduct regular follow-up and health guidance, so as to improve medication adherence of elderly patients with polypharmacy.

Bortezomib (5ng/mL, 10ng/mL, 20ng/mL and 40ng/mL) treatment for 24h, 48h and 72h, the apoptosis rate of Jurkat cells increased with the increase of drug concentration and the prolongation of action time, the differences were statistically significant( F=1 288.571, 223.378, 251.175, all P<0.05). The expression of Bax mRNA in Jurkat cells increased with the increase of drug concentration and time( F=258.446, 518.929, 276.764, all P<0.05). The Bcl-2 mRNA and Cox-2 mRNA expression levels decreased with the increase of drug concentration and the prolongation of action time( FBcl-2 mRNA=236.848, 264.849, 343.968, FCox-2 mRNA=679.404, 1288.681, 1541.850, all P<0.05). Conclusion:Bortezomib can inhibit the proliferation and induce apoptosis of Jurkat cells.Bortezomib can increase the expression of Bax mRNA and decrease the expression of Bcl-2 and Cox-2 mRNA, which may be the molecular mechanism of bortezomib to promote apoptosis.
