Elemene is widely recognized as an effective anti-cancer compound and is routinely administered in Chinese clinical settings for the management of several solid tumors, including non-small cell lung cancer (NSCLC). However, its detailed molecular mechanism has not been adequately demonstrated. In this research, it was demonstrated that elemene effectively curtailed NSCLC growth in the patient-derived xenograft (PDX) model. Mechanistically, employing high-throughput screening techniques and subsequent biochemical validations such as microscale thermophoresis (MST), microRNA-145-5p (miR-145-5p) was pinpointed as a critical target through which elemene exerts its anti-tumor effects. Interestingly, elemene serves as a binding stabilizer for miR-145-5p, demonstrating a strong binding affinity (dissociation constant (K _D) = 0.39 ± 0.17 μg/mL) and preventing its degradation both in vitro and in vivo, while not interfering with the synthesis of the primary microRNA transcripts (pri-miRNAs) and precursor miRNAs (pre-miRNAs). The stabilization of miR-145-5p by elemene resulted in an increased level of this miRNA, subsequently suppressing NSCLC progression through the miR-145-5p/mitogen-activated protein kinase kinase kinase 3 (MAP3K3)/nuclear factor kappaB (NF-κB) pathway. Our findings provide a new perspective on revealing the interaction patterns between clinical anti-tumor drugs and miRNAs.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective:To investigate the effects of miRNA-628-3p (miR-628-3p) on the proliferation, apoptosis and invasion of non-small cell lung cancer H1299 cells and its targeting relationship with insulin-like growth factor 1 receptor (IGF-1R).Methods:The blank control group (untreated H1299 cells), miR-NC group (H1299 cells transfected with empty plasmid), miR-628-3p-M group (H1299 cells transfected with miR-628-3p mimic sequence plasmid) and miR-628-3p-I group (H1299 cells transfected with miR-628-3p inhibitory sequence plasmid) were established. The cells in each group were cultured for 72 h, and the cell proliferation ability was detected by methyl thiazol tetrazolium (MTT) method, the number of cell monoclonal formation was determined by crystal violet staining, the level of cell apoptosis was determined by flow cytometry, and the cell invasion ability was determined by Transwell method. The mRNA levels of miR-628-3p and IGF-1R in cells were determined by real-time fluorescence quantitative reverse transcription polymerase chain reaction (qRT-PCR), and the protein level of IGF-1R in cells was determined by Western blotting.Results:Compared with the blank control group and miR-NC group, the cell survival rate [(42±7)% vs. (78±6)%, (76±7)%], the number of monoclonal formation [235±35 vs. 614±89, 618±75], the number of invasive cells [(265±85) cells vs. (693±185) cells, (703±119) cells], relative expression of IGF-1R mRNA (2.17±0.14 vs. 3.38±0.15, 3.37±0.13) and relative expression of IGF-1R protein (0.34±0.13 vs. 0.89±0.19, 0.88±0.18) in the miR-628-3p-M group were lower (all P < 0.05), but the apoptosis rate [(9.30±3.51)% vs. (3.30±1.54)%, (3.10±1.94)%] and relative expression of miR-628-3p (6.93±0.17 vs. 3.29±0.15, 3.30±0.16) were higher (all P < 0.05); the cell survival rate [(90±6)%], the number of monoclonal formation (1 063±102), the number of invasive cells [(1 985±426) cells], relative expression of IGF-1R mRNA (4.30±0.18) and relative expression of IGF-1R protein (1.47±0.17) in the miR-628-3p-I group were higher (all P < 0.05), but the apoptosis rate [(0.90±0.20)%] and the relative expression of miR-628-3p (1.93±0.18) were lower (both P < 0.05). Compared with the miR-628-3p-M group, the miR-628-3p-I group had higher cell survival rate, the number of monoclonal formation, the number of invasive cells, and the relative expressions of IGF-1R mRNA and protein (all P < 0.05), but the apoptosis rate and relative expression of miR-628-3p were lower (both P < 0.05). Conclusions:After regulation of miR-628-3p level, the proliferation, migration and invasion of H1299 cells are affected. miR-628-3p may have a targeting relationship with IGF-1R.

Radiation exposure is an ongoing and serious threat in military and public health concern, and there is an unmet need for effective preventative or mitigative treatment against radiation-induced injuries. The handful of FDA approved radiation protection agents cannot be widely used due to their side effects. Some natural non-toxic compounds such as bee products have been reported to prevent and treat radiation-induced injuries of oral mucosa, esophagus, skin, liver, intestine and hemopoietic system by reducing radiation-induced oxidative stress, apoptosis and DNA damage, indicating that they may be potential options of safe radioprotective agents. In this paper, the experimental and clinical studies on prevention and treatment of radiation injury by bee products were reviewed.

Objective    To compare the effects of transthoracic device closure and surgical closure on ventricular septal defect systemically. Methods    A systematic literature search was conducted using the PubMed, EMbase, The Cochrane Library, VIP, CNKI, CBM, Chinese Clinical Trial Register, ClinicalTrials. gov and Wanfang Database up to July 31, 2016. Quality was assessed and data of included articles were extracted. The meta-analysis was conducted using RevMan 5.0 and Stata 14.0 software. Results    Eleven studies were identified, including 5 RCTs and 6 cohort studies involving 2 504 patients. For success rate, there was no statistical difference between the transthoracic closure group and the surgical closure group in RCT (RR=0.99, 95%CI 0.96 to 1.03, P=0.70); the success rate in the transthoracic closure group was lower than that in the surgical closure group in the cohort study (OR=0.21, 95%CI 0.08 to 0.55, P=0.002). Both  results of RCTs and cohort studies showed that compared with surgical closure, transthoracic device closure reduced duration of the operation (RCT MD=–79.38, 95%CI –95.00 to –63.76, P<0.000 01; cohort study MD=–66.26, 95%CI –71.20 to –61.31, P<0.000 01) and hospital stay (RCT MD=–2.10, 95%CI –2.65 to –1.55, P<0.000 01; cohort study MD=–3.99, 95%CI –6.03 to –1.94, P=0.000 1), and the patients with blood transfusion (RCT RR= 0.04, 95%CI 0.01 to 0.11, P<0.000 01; cohort study OR=0.01, 95%CI 0.00 to 0.13, P=0.001). In the transthoracic closure group the risk of postoperative arrhythmia reduced (RCT RR=0.20, 95%CI 0.13 to 0.32, P<0.000 01; cohort study OR=0.46, 95%CI 0.31 to 0.67, P<0.000 1). In the transthoracic closure group a higher postoperative valvular regurgitation risk in RCT induced (RR=1.45, 95%CI 1.07 to 1.96, P=0.02) and the rate of postoperative valvular regurgitation in cohort study reduced (OR=0.43, 95%CI 0.20 to 0.92, P=0.03). However, there was no statistical difference in postoperative residual shunt (RCT RR=0.96, 95%CI 0.57 to 1.62, P=0.89; cohort study OR=0.52, 95%CI 0.12 to 2.25, P=0.38). Conclusion    Transthoracic device closure can shorten duration of the operation, hospital stay and reduce the patients with blood transfusion and post- and intraoperative arrhythmia risk. Therefore, transthoracic device closure may be a better approach for some ventricular septal defect patients.

Objective To explore the correlation between the self-management and self-efficacy of senile patients with chronic heart failure (CHF). Methods In this study, the conveninent sampling method was adopted. From June to December 2016, totally 416 senile CHF patients hospitalized in the Department of Cardiology of 5 general class Ⅲ grade A hospitals in Xi'an were investigated with the general demographic data questionnaire, self-management scale for CHF patients and chronic disease self-efficacy scale. Results The score of self-management in the senile CHF patients in Xi'an totaled (50.76±9.98), with a scoring rate of 63.5%; the scores of medication management, food and beverage management, psychological and social management and symptom management were (13.38±3.38), (7.89±2.14), (12.81±2.91) and (16.69±4.26), with the scoring rates of 66.9%, 65.8%, 64.1% and 59.6%, respectively, showing a medium level; and there was statistically significant difference in the total self-management score between patients with different marital status, per capita income and heart function grading (t=-2.443, 10.906, 16.229;P<0.05). The score of self-efficacy totaled (34.30±11.90), with a scoring rate of 57.17%, showing a medium level. The correlation analysis showed that there was a positive correlation between self-efficacy and self-management (r=0.161, P< 0.05). Conclusions The self-management and self-efficacy of the senile CHF patients in Xi'an remain at a medium level, which could be possibly improved, and the two are closely correlated. The results suggest that we should pay more attention to the patient's management confidence in the disease itself, attach importance to their psychological and social support and enhance their self-efficacy, thus improving their self-management. This is of great significance in controlling CHF and improving the patient's quality of life.

Objective To study the effect of lithium chloride on the gap junction in the myocardium under chronic hypoxia.Methods Twenty-five C57BL/6J mice were randomly divided into normoxia group,hypoxia group,normoxic control group,hypoxia + saline group and hypoxia + lithium chloride group.Hypoxia group was treated with 10％ oxygen concentration for 4 weeks.Hypoxia + saline group and hypoxia + lithium chloride group were intraperitoneal injection of saline and lithium chloride.Electrophysiology and cardiac catheterization were used to assess arrhythmias,heart rate and ejection fraction.The expression of Cx43,phosphorylated glycogen synthase kinase 3β(p-GSK-3β) and glycogen synthase kinase 3β (GSK-3β) were detected by Western blot.Results Compared with the normoxia group,the hypoxia group had a faster heart rate [(448 ± 18) bpm vs.(401 ± 13) bpm,P＜0.05),and the ejection fraction was decreased [(56±5)％ vs.73±4)％,P＜0.05],arrhythmia score increased [(3.4±0.5)％ vs.(0.6±0.5)％,P＜0.05],Cx43 expression was decreased.Compared to hypoxia + normal saline group,the heart rate decreased[(412±11)bpm vs.(454±18)bpm,P＜0.05],ejection fraction increased[(69±3)％ vs.(55±4)％,P＜0.05],the score of arrhythmia decreased [(1.8±0.4) ％ vs.(3.0±0.7)％,P＜0.05] in hypoxia + lithium chloride group,the expression of Cx43 and the rate of p-GSK-3β to GSK-3β were increased.Conclusion During the chronic hypoxia,lithium chloride can sustain the gap junction through inhibition of GSK-3β signaling way,which can also reduce the rate of arrhythmia.
