Green prescription is a written prescription aimed at improving health by promoting physical activity and improving diet， with advantages such as high cost-effectiveness， strong feasibility， and minimal harm to patients. The theory of traditional Chinese medicine （TCM） green prescription integrates the health philosophy of "following rule of yin and yang， and adjusting ways to cultivating health"， the exercise philosophy of balancing yin-yang and the five elements， and the dietary philosophy of moderation and balance， which embody core TCM concepts such as treating disease before its onset and harmony between humans and nature. It has also developed traditional exercise practices like Tai Chi， Baduanjin， Wuqinxi， Yi-Gin-Ching， and Qigong， as well as dietary adjustments like medicated diet and herbal wines. However， it is believed that the TCM green prescription currently suffers from insufficient evidence-based research， low patient awareness and acceptance， and weak basic research. Based on this， it is proposed that large-sample clinical trials should be conducted in the future to improve the quality of evidence-based medicine， basic research can be carried out with the help of artificial intelligence and other methods in research design， the hospital information system （HIS） can be used for control at the implementation level， and publicity and patient education can be strengthened through the new media， so as to promote the development and application of the TCM green prescriptions in the field of global health treatment.

Senescence, a stable state of growth arrest, affects many physiological and pathophysiological processes, especially aging. Previous work has indicated that transcription factors (TFs) play a role in regulating senescence. However, a systematic study of regulatory TFs during replicative senescence (RS) using multi-omics analysis is still lacking. Here, we generated time-resolved RNA-seq, reduced representation bisulfite sequencing (RRBS) and ATAC-seq datasets during RS of mouse skin fibroblasts, which demonstrated that an enhanced inflammatory response and reduced proliferative capacity were the main characteristics of RS in both the transcriptome and epigenome. Through integrative analysis and genetic manipulations, we found that transcription factors E2F4, TEAD1 and AP-1 are key regulators of RS. Overexpression of E2f4 improved cellular proliferative capacity, attenuated SA-β-Gal activity and changed RS-associated differentially methylated sites (DMSs). Moreover, knockdown of Tead1 attenuated SA-β-Gal activity and partially altered the RS-associated transcriptome. In addition, knockdown of Atf3, one member of AP-1 superfamily TFs, reduced Cdkn2a (p16) expression in pre-senescent fibroblasts. Taken together, the results of this study identified transcription factors regulating the senescence program through multi-omics analysis, providing potential therapeutic targets for anti-aging.

Objective:To evaluate the cerebral blood flow circulation time (CCT) by contrast-enhanced ultrasound, and to explore the change rule of CCT in different degree of intracranial pressure, so as to provide a new method for non-invasive monitoring of intracranial pressure.Methods:Ten patients with hemorrhagic stroke or acute craniocerebral trauma with increased intracranial pressure were selected from Tangdu Hospital, the Air Force Military Medical University from January to December 2019. Contrast-enhanced ultrasound was performed when the invasive intracranial pressure (iICP) increased (>20 mmHg, iICP increased group) and decreased to normal (≤20 mmHg, iICP normal group), CCT was measured and analyzed. The differences of CCTs between different iICP groups were compared and the relationship between CCT and iICP was analyzed.Results:①The CCT on the lesion sides of the same patients in the iICP increased group was significantly longer than in the iICP normal group[(9.34±2.58)s vs (6.48±1.91)s, P=0.002]. ②When iICP was increased in patients with hemorrhagic stroke or acute craniocerebral trauma, the CCTs of the diseased side and the non-pathological side were not statistically significant [(9.34±2.58)s vs (9.01±3.22)s, P=0.809]. ③Pearson correlation analysis and Spearman rank correlation analysis showed that there were no correlations between patient′s breathing, heart rate, carbon dioxide partial pressure, body temperature, GCS score and CCT (all P>0.05). Age, mean arterial pressure and CCT were moderately correlated ( r=0.518, 0.463 and P=0.023, 0.046, respectively). ④Logistic regression analysis showed that CCT was an independent risk factor related to intracranial hypertension( OR=0.7, 95% CI=0.47-0.95, P=0.036). The area under ROC curve (AUC) predicted by logistic regression was 0.750(0.588~0.912). Conclusions:Contrast-enhanced ultrasound noninvasive assessment of CCT can reflect the intracranial pressure in patients with hemorrhagic stroke or acute traumatic brain injury, and CCT has a predictive value for intracranial hypertension. When the patient has limited conditions for invasive intracranial pressure monitoring, or when the invasive monitoring probe is pulled out but still needs to evaluate intracranial pressure, the change of CCT can provide an effective reference for clinical diagnosis and treatment.

One major strategy to generate genetically modified mouse models is gene targeting in mouse embryonic stem (ES) cells, which is used to produce gene-targeted mice for wide applications in biomedicine. However, a major bottleneck in this approach is that the robustness of germline transmission of gene-targeted ES cells can be significantly reduced by their genetic and epigenetic instability after long-term culturing, which impairs the efficiency and robustness of mouse model generation. Recently, we have established a new type of pluripotent cells termed extended pluripotent stem (EPS) cells, which have superior developmental potency and robust germline competence compared to conventional mouse ES cells. In this study, we demonstrate that mouse EPS cells well maintain developmental potency and genetic stability after long-term passage. Based on gene targeting in mouse EPS cells, we established a new approach to directly and rapidly generate gene-targeted mouse models through tetraploid complementation, which could be accomplished in approximately 2 months. Importantly, using this approach, we successfully constructed mouse models in which the human interleukin 3 (IL3) or interleukin 6 (IL6) gene was knocked into its corresponding locus in the mouse genome. Our study demonstrates the feasibility of using mouse EPS cells to rapidly generate mouse models by gene targeting, which have great application potential in biomedical research.

Objective To evaluate the value of lung ultrasound score (LUS) in the quantitative assessment of the severity of neonatal respiratory distress syndrome (NRDS) and the value of clinical diagnosis and treatment.Methods Totally 74 NRDS cases and 30 normal neonates were studied.LUS was compared with X-ray examination,clinical data,ventilator assisted ventilation and ventilator parameters.ROC curve was used to calculate sensitivity and specificity of LUS to predict the severity of NRDS and application of invasive ventilator treatment.Results The main findings of the lung ultrasound in NRDS included diffuse distribution of dense B line,disappeared A line,pleural line abnormalities,decreased pulmonary slip sign and pulmonary consolidation.LUS in patients with NRDS was significantly correlated with X ray grades,clinical grades,assisted ventilation mode grades,number of days on ventilator and ventilator parameters (all P＜0.05).LUS value to predict mild,moderate and severe NRDS were 13.0,22.5,and 29.5,respectively.The best cutoff point for LUS to predict the adoptation of invasive assisted ventilation was 22.5,which had sensitivity of 86.0 ％ and specificity of 64.5 ％.Conclusion LUS can be used to diagnose and evaluate the severity of the desease,and to guide the clinical diagnosis and treatment.

Objective To investigate the clinical value of coronary artery Z-scores on echocardiography in diagnosing coronary artery abnormalities. Methods The echocardiography results of 612 patients with Kawasaki disease (KD) at the acute and recovery phase were retrospectively studied. Coronary artery luminal diameters were converted to body-surface-area-adjusted Z-scores. According to coronary Z-scores classiifcation, all the subjects were divided to four groups:415 cases with no dilation (ND), 133 cases with small coronary artery abnormalities (SCAAs), 47 cases with large coronary artery abnormalities (LCAAs), and 17 cases with giant coronary artery abnormalities (GCAAs). Clinical features (gender, age, typical clinical manifestations, fever duration) and laboratory results (CRP, ESR, WBC, PLT) were compared among all the four groups. Coronary artery diameters and the Z-scores were compared between acute and convalescence phase. Results Along with the increase of coronary Z-score, fever duration was prolonged [ND group:(7.75±3.12) d, SCAAs group (8.50±4.12) d, LCAAs group: (8.57±3.58) d, GCAAs group: (11.88±4.33) d, F=22.375, P<0.05]. With coronary Z-score increasing, PLT also increased (F=22.029, P=0.000), and the highest PLT was observed in GCAAs group. There were no significant differences in the CRP, ESR and WBC among all the four groups (F=0.236, 1.116, 0.121, all P>0.05). No significant different coronary diameters were found in ND cases between recovery and acute phase [(2.24±0.34) mm vs (2.33±0.36) mm, t=1.926, P > 0.05]. But there were significant difference in the coronary Z-scores of ND patients between recovery and acute phase (0.41±0.82 vs 1.17±0.75, t=8.332, P < 0.05). The coronary Z-scores in SCAAs group (1.32±0.89 vs 3.40±0.62, t=11.073, P < 0.05), LCAAs group (3.12±2.27 vs 6.20±1.28, t=4.579, P<0.05) and GCAAs group (11.88±6.77 vs 20.4±9.70, t=3.480, P<0.05) at recovery phase were smaller than values at acute phase. Conclusions The KD coronary Z-scores are the body-surface-area-adjusted standard value, and not subject to the influence of children growth and development. Therefore, it may accurately evaluate the severity of coronary artery abnormalities and its recovery process. Accurate quantitative of the coronary artery luminal dimensions is important in KD clinical management and prognosis prediction.

Objective To investigate the calculation method and its inlfuencing factors of Z scores in the aortic root diameters measured by echocardiography in children. Methods A total of 105 children with median age 19 months, who came to Shenzhen Children′s Hospital from March 2012 to October 2012 were included. The diameters of aortic ring (ARD) and aortic sinus (ASD) were measured by two dimension echocardiography, Z scores of ARD and ASD were calculated using two different normal reference values regression equation and mean square error derived from Shenzhen children′s hospital (C method) and Pettersen et al (P method). The regression equation from C method and body surface area (BSA) formula from P method were adopted to calculate Z scores of ARD and ASD (ZH method). The Z results of ARD and ASD calculated by those three methods were compared and were analyzed for their normality probability distributions. Results Z scores of ARD and ASD derived from C method were all showed as normal distribution (P=0.067 and 0.650). Z scores of ARD and ASD derived from P method were all showed as normal distribution (P=0.208 and 0.970). Z score of ARD derived from ZH method was showed as non-normal distribution (P=0.027), but Z score of ASD was normal distribution (P=0.430). There were no significant differences in ARD-Z calculated by C method (0.41±0.89), P method (0.23±0.85) and ZH method (0.36±0.94) (F=1.117, P=0.309). There were signiifcant differences in the Z scores of ASD calculated by C method (0.38±0.89), P method (0.58±0.71) and ZH method (0.36±0.84) (F=5.443, P=0.005). Z scores of ARD (r=0.917, P=0.000) and ASD (r=0.900, P=0.000) calculated by C method correlated well with that by P method. Conclusions Calculation method of BSA and normal reference values regression equation were the main influencing factors of Z score value in quantifying children aortic root diameters by echocardiography. For the clinical applications. The normal reference value should be used which is suitable for the Chinese children.

The event-related potential (ERP) P300 was recorded to analyze the temporal sequences character and the P300 compositions in premeditated and temporary deception. When 15 healthy undergraduates watched the stolen, familiar but not stolen and strange object pictures, the reaction time was recorded and EEG data were collected to analyze the amplitudes of N1, N2 and P3 sub-component of P300 in honesty and deception group respectively through analog theft paradigm. The results showed that the amplitudes of N1, N2 and P3 in premeditated deception group were markedly larger than those in temporary deception, and the reaction time of deception group was longer than that of honesty group. Compared with temporary deception, more attention resources were invested and intensely response conflict was induced by premeditated deception.

Objective To explore factors influencing the prognosis of hepatocellular carcinoma (HCC) patients after hepatectomy. Methods From May 1994 to January 1998, 189 patients who underwent hepatectomy for HCC were enrolled for reviewing their clinical characteristics, treatment and prognosis. Twenty-two parameters contributing to long-term survival rate (SR) and disease-free SR were analysed. Results The 3,5-year cumulative SR of the whole group was 63%,45%, respectively. The 3,5-year SR and disease-free SR in the curative resection (CR) group ( n =162) were 67%,47% and 45%,26% respectively. Results showed that the way by which a tumor was found, tumor size, portal tumor thrombi, satellite nodule, TNM stage, cirrhosis type, recurrent and treatment, blood transfusion, differentiation grade,and CR were risk factors by individual variable analysis( P =0.0000～0.0034); A multivariable analysis showed that CR, tumor size, tumor finding mode and reoperation were significant factors associating with prognosis( P =0.0000～0.0024). Blood transfusion and type of cirrhosis were closely correlated with tumor-free survival ( P =0.0001). Conclusions Curative resection, tumor size, reoperation for recurrence were important factors for recurrence by multivariate analysis. The severity of concomittant liver cirrhosis and perioperative blood transfusion were closely correlated with postoperative tumor free survival.
