Exploring the action targets (groups) of traditional Chinese medicine (TCM) is an important proposition to promote the innovation and development of TCM, but it has attracted a lot of attention as to whether it is related to the efficacy or the disease. Our team found that the metabolomic signature molecules in the development of diabetes mellitus (DM) were significantly associated with the clinical efficacy of Yuquan Pill through a large clinical sample study. Taking this as a clue, our team intends to expand the information on the omics features of DM development, and discover the key targets (groups) and their lead compounds for the hypoglycemic effect of Yuquan Pill. The project includes: ① Based on the retrospective clinical trials, using omics technology integrated with generative artificial intelligence, mining the characteristic information of proteome and microbiome, forming driving factors together with metabolome characteristic molecules, and characterizing the molecular trajectories of diabetes evolution and their interference by Yuquan Pill; ② Taking the evolving molecular trajectories as a link and pointer, using anthropomorphic modeling and molecular biology techniques such as chemical proteomics to discover the key targets (groups) of Yuquan Pill's hypoglycemic effect, with the prospective clinical samples for validation; ③ Evaluate the overall response of key targets (groups) using graph neural network technology, and search for drug-derived/endogenous lead compounds with proven clinical pathologies and clear mechanisms of action, so as to provide a new paradigm and technology for the discovery of complex active ingredient targets (groups) of TCM that are related to their clinical efficacy, as well as for the discovery of innovative medicines.

OBJECTIVE: Appraisal of treatment outcomes in integrative medicine is a challenge due to a gap between the concepts of Western medicine (WM) disease and traditional Chinese medicine (TCM) syndrome. This study presents an approach for the appraisal of integrative medicine that is based on targeted metabolomics. We use non-alcoholic fatty liver disease with spleen deficiency syndrome as a test case. METHODS: A patient-reported outcome (PRO) scale was developed based on literature review, Delphi consensus survey, and reliability and validity test, to quantitatively evaluate spleen deficiency syndrome. Then, a metabonomic foundation for the treatment of non-alcoholic fatty liver disease with spleen deficiency syndrome was identified via a longitudinal interventional trial and targeted metabolomics. Finally, an integrated appraisal model was established by identifying metabolites that responded in the treatment of WM disease and TCM syndrome as positive outcomes and using other aspects of the metabonomic foundation as independent variables. RESULTS: Ten symptoms and signs were included in the spleen deficiency PRO scale. The internal reliability, content validity, discriminative validity and structural validity of the scale were all qualified. Based on treatment responses to treatments for WM disease (homeostasis model assessment of insulin resistance) or TCM syndrome (spleen deficiency PRO scale score) from a previous randomized controlled trial, two cohorts comprised of 30 participants each were established for targeted metabolomics detection. Twenty-five metabolites were found to be involved in successful treatment outcomes to both WM and TCM, following quantitative comparison and multivariate analysis. Finally, the model of the integrated appraisal system was exploratively established using binary logistic regression; it included 9 core metabolites and had the prediction probability of 83.3%. CONCLUSION This study presented a new and comprehensive research route for integrative appraisal of treatment outcomes for WM disease and TCM syndrome. Critical research techniques used in this research included the development of a TCM syndrome assessment tool, a longitudinal interventional trial with verified TCM treatment, identification of homogeneous metabolites, and statistical modeling.

Objective:To analyze the status quo and development of the Hope Houses for individuals with spinal cord injury (SCI) in Shanghai. Methods:In June, 2018, the organizers and managers of Hope Houses from 16 districts in Shanghai were investigated with the self-designed questionnaires, which covered the personal characteristics, knowledge of related policy, development of projects and obstacles, and rehabilitation recognition. The descriptive analysis and correlational analyses were conducted. Results:Totally, eleven organizers and 16 managers were investigated. The knowledge of related policy for organizers was not good enough. Eight Hope Houses in 16 districts in Shanghai were operated by social organizations. The average implementation rate of projects in Hope Houses was 60.6%, and the highest was rehabilitation knowledge education (96.3%). There was insufficient provision in legal services, job skills training, rehabilitation nursing guidance, job referral, medical referral and education referral, etc. The main related factors limiting the development of the Hope Houses were lacks of budgets, social consensus and professionals. The rehabilitation cognition of organizers and managers was generally good, but the cognition of rehabilitation principles and rehabilitation value needed to be strengthened. Conclusion:The Hope Houses for individuals with SCI in Shanghai work well, and the rehabilitation cognition of organizers and managers is satisfactory. It should be strenghened in resource input, comprehensive rehabilitation and standard of management, to expand the service timely.

OBJECTIVE: To observe the changes of relative expression of myocardial various RNAs in rats died of different causes and their relationship with PMI. METHODS: The rat models were established in which the rats were sacrificed by broken neck, asphyxia, and hemorrhagic shock. Total RNAs were extracted from myocardium. The quantitative real time PCR was used to calculate threshold cycle values of RNAs including glyceraldehyde-3-phosphate dehydrogenase (GAPDH), beta-actin, inducible nitric oxide synthase (iNOS), hypoxia-inducible factor-1 (HIF-1), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and U6 small nuclear RNA (U6 snRNA) and to study the changes of the relative expressions of various indexes with PMI. RESULTS: U6 snRNA with stable expression level could be used as appropriate internal control. In the early PMI, the relative expression of GAPDH, HIF-1, iNOS, TNF-alpha, and IL-6 more characteristically increased in groups of asphyxia and hemorrhagic shock than in group of broken neck, but the quantity of beta-actin decreased in all groups. In the late PMI, all the relative expressions significantly declined in correlation with the degradation of RNA. CONCLUSION The characteristic changes of each RNA expression can be used as references to estimate PMI in deaths by different causes.

BACKGROUNDCyanotic congenital heart defects with decreased pulmonary blood flow due to lung ischemia, hypoxia, and others lead to infant morbidity and mortality more than acyanotic heart disease does. Despite the great effort of medical research, their genetic link and underlying microRNAs molecular mechanisms remain obscure. In this study, we aimed to investigate microRNAs regulation during cyanotic defects in lung of immature piglets.

METHODSCyanotic piglet model was induced by main pulmonary artery-left atrium shunt with distal pulmonary artery banding. Four weeks later, hemodynamic parameters confirmed the development of cyanotic defects and pulmonary lobe RNA was extracted from all animals. We studied the repertoire of porcine lung microRNAs by Solexa deep sequencing technology and quantified highly expressed microRNAs by microarray hybridization. Furthermore, we quantitated selected microRNAs from cyanotic and control piglets by quantitative RT-PCR.

RESULTSAfter surgical procedure 4 weeks later, the cyanotic model produced lower arterial oxygen tension, arterial oxygen saturation, and higher arterial carbon dioxide tension, hematocrit and hemoglobin concentration than controls (all P < 0.05). In 1273 miRNAs expressed in the immature piglets lungs, 2 most abundant microRNAs (miR-370 and miR-320) demonstrated significant difference between cyanotic and control group (all P < 0.05).

CONCLUSIONOur results extended lung microRNA profile in immature piglets and suggested that miR-370 and miR-320 are significantly up-regulated in cyanotic lung tissues.

BACKGROUNDCyanotic patients have potential growth retardation and malnutrition due to hypoxemia and other reasons. Ghrelin is a novel endogenous growth hormone secretagogue that has effects on growth and cardiovascular activities. The aim of this study was to evaluate the plasma level and myocardial expression of ghrelin and insulin-like growth factor-1 (IGF-1) using an immature piglet model of chronic cyanotic congenital heart defects with decreased pulmonary blood flow.

METHODSTwelve weanling Chinese piglets underwent procedures of main pulmonary artery-left atrium shunt with pulmonary artery banding or sham operation as control. Four weeks later, hemodynamic parameters were measured. Enzyme-linked immunosorbent assay for plasma ghrelin and IGF-1 level measurement were performed. Ventricular ghrelin and IGF-1 mRNA expressions were measured by quantitative real-time polymerase chain reaction.

RESULTSFour weeks after surgical procedure, the cyanotic model produced lower arterial oxygen tension ((68.73 ± 15.09) mmHg), arterial oxygen saturation ((82.35 ± 8.63)%), and higher arterial carbon dioxide tension ((51.83 ± 6.12) mmHg), hematocrit ((42.67 ± 3.83)%) and hemoglobin concentration ((138.17 ± 16.73) g/L) than the control piglets ((194.08 ± 98.79) mmHg, (96.43 ± 7.91)%, (36.9 ± 4.73) mmHg, (31.17 ± 3.71)%, (109.83 ± 13.75) g/L) (all P < 0.05). Plasma ghrelin level was significantly higher in the cyanotic model group in comparison to the control (P = 0.004), and the plasma IGF-1 level was significantly lower than control (P = 0.030). Compared with control animals, the expression of ghrelin mRNAs in the ventricular myocardium was significantly decreased in the cyanotic model group (P = 0.000), and the expression of IGF-1 mRNAs was elevated (P = 0.001).

CONCLUSIONSChronic cyanotic congenital heart defects model was successfully established. Plasma ghrelin level and myocardial IGF-1 mRNA expression were significantly up-regulated, while plasma IGF-1 level and myocardial ghrelin mRNA expression were down-regulated in the chronic cyanotic immature piglets. The ghrelin system may be an important part of the network regulating cardiac performance.

BACKGROUNDThe non-operation treatment of intra-abdominal trauma guided contrast enhanced ultrasound (CEUS) is one of the hottest research topic. Gelatin/thrombin/calcium (GTC) was developed as a novel haemostatic agent for non-operable intra-abdominal trauma. We hypothesized that GTC can achieve haemostasis (without the use of pressure) within a short time in a large wound model by percutaneous injection under CEUS guidance.

METHODSForty Wister rats received large liver injuries by haemostatic clamp and were randomly divided into four groups, according to the haemostatic agent used. These included normal saline (NS) group A, lyophilising thrombin powder (LTP) group B, GTC group C, and absorbable α-cyanoacrylate (ACNA) group D. Each injury site was treated with one of the above materials and total bleeding time was recorded. All liver wounds were evaluated using CEUS at three periods: pre-injury, injury and post-treatment. The liver wounds were also evaluated by histology 3, 6, and 9 days after injury and the extents of abdominal adhesions were recorded.

RESULTSThe sensitivity of CEUS (100%) in detecting blunt traumatic liver lesions was significantly higher than conventional ultrasound (42.5%). Bleeding times at the injury site in the GTC group C ((129.3 ± 14.0) seconds) and ACNA group D ((5.2 ± 1.0) seconds) were significantly shorter than those in the NS group A ((369.5 ± 48.8) seconds, P < 0.01) and LTP group B ((324.7 ± 52.22) seconds, P < 0.01). The LTP group B showed no significant difference compared with the NS group A. Gross examination of liver tissue revealed that there were fewer intra-abdominal adhesions in the GTC group C (10%) than in the ACNA group D (100%). Histopathologic examination showed that GTC was completely absorbed after nine days.

CONCLUSIONSGTC, delivered by percutaneous injection under CEUS, may achieve haemostasis (without the use of pressure) within a short time in a large wound model. GTC is absorbable and may prevent intra-abdominal adhesions. Therefore, it may be the optimal choice for first aid treatment of large abdominal wounds in the setting of blunt trauma.

BACKGROUNDRhoA/Rho kinase (ROCK) pathway is involved in pulmonary arterial hypertension (PAH) and pulmonary artery smooth muscle cell (PASMC) proliferation. Inhibition of ROCK has been proposed as a treatment for PAH. But the mechanism of RhoA/ROCK pathway and its downstream signaling in proliferation of human PASMCs is unclear. We investigated the effect of fasudil, a selective ROCK inhibitor, on platelet-derived growth factor (PDGF) induced human PASMC proliferation, and the possible association between RhoA/ROCK and extracellular signal-regulated kinase (ERK), p27(Kip1).

METHODSHuman PASMCs were cultured with the stimulation of 10 ng/ml PDGF, and different concentrations of fasudil were added before the addition of mitogen. Cell viability and cell cycle were determined with MTT and flow cytometry respectively. ROCK activity, ERK activity and protein expression of proliferating cell nuclear angigen (PCNA) and p27(Kip1) were measured by immunoblotting.

RESULTSBy MTT assay, PDGF significantly increased the OD value that represented human PASMC proliferation, and pretreatment with fasudil significantly reversed this effect in a dose-dependent manner. After PDGF stimulation, the percentage of cells in S phase increased dramatically from 15.6% to 24.3%, while the percentage in G(0)/G(1) phase was reduced from 80.6% to 59%. And pretreatment with fasudil reversed the cell cycle effect of PDGF significantly in a dose-dependent manner. PDGF markedly induced ROCK activity and ERK activity with a peak at 15 minutes, which were significantly inhibited by fasudil. In addition, fasudil significantly inhibited PDGF-induced PCNA expression and fasudil also upregulated p27(Kip1) expression in human PASMCs, which decreased after PDGF stimulation.

CONCLUSIONRhoA/ROCK is vital for PDFG-induced human PASMC proliferation, and fasudil effectively inhibited PDGF-induced human PASMC proliferation by up-regulation of p27(Kip1), which may be associated with inhibition of ERK activity.
