Objective To study the effect of metastasis-associated in colon cancer 1 ( MACC1 ) inhibition by small interference RNA( siRNA) on the formation of tumor cells that promote blood vessels, and to explore its possible molecular mechanism.Methods Synthesized MACC1 specific siRNA was transfected into human lung cancer cell lines XWLC-05. Then, the inhibitory effect of siRNA on the protein level of MET, MEK/p-MEK, ERK/p-ERK, and AKT/p-AKT was detected using Western blotting while the change in VEGF, bFGF and IL-8 protein level was detected using ELISA method. Results Western blotting results indicated that the expression level of MET, p-MEK and p-ERK was significantly decreased in the XWLC-05 cells transfected by MACC1 specific siRNA compared with control and nonsense siRNA groups, but the expression of total protein MEK and ERK did not change.Furthermore, the level of AKT and phosphorylated protein was not affected.ELISA results suggested that the secretion level of VEGF, bFGF and IL-8 was significantly suppressed at 48 h or 72 h compared with control and nonsense siRNA groups.Conclusion MACC1 may reduce the secretion levels of VEGF, bFGF and IL-8 via HGF/c-Met and MEK/ERK signal transduction pathways, and regulate angiogenesis of lung cancer.

Objective To study the effect of liensinine on the proliferation of human bladder cancer T24 cells.Methods T24 cells were treated with different concentrations of liensinine.Its influence on the cell proliferation was detected by the CCK-8 exper-iment and the clonogenic experiment.After staining of T24 cells,the influence of liensinine on the cell cycle was examined by the flow cytometry.The mRNA change of p2 1 gene was determined by real-time quantitative PCR.Results Compared with the con-trol,liensinine significantly inhibited the proliferation of T24 cells in different doses groups(1.562 5,3.125 0,6.250 0,12.500 0, 25.000 0μg/mL),the differences had statistical significance and showed the dose-dependence;the cell cycle detection results re-vealed that liensinine arrested the T24 cells at the S phase;the real-time quantitative PCR detection results showed that liensinine increased mRNA of p21 gene in T24 cells.Conclusion Liensinine inhibits the proliferation of T24 bladder cancer cells and arrests the T24 cells at S phase,its mechanism may be related with the upregulation of p21 expression.

Objective To observe the effect of perioperative rehabilitation on anterior spinal cord syndrome caused by cervical hyper-flexion injury. Methods Sixty-nine inpatients with anterior spinal cord syndrome after cervical hyperflexion injury from January, 2012 to De-cember, 2014 were reviewed. 32 cases (group A) accepted systematic rehabilitations and other 37 cases (group B) did not. They were as-sessed with Japanese Orthopaedic Association (JOA) scores preoperatively and 1-year follow-up. Results All the patients succeeded in the operation. The JOA score improved more 1 year follow-up in group A than group B (t=2.538, P=0.044). Conclusion Systematic rehabilita-tion may work in the management of anterior spinal cord syndrome after cervical hyperflexion injury.

In this study, we explored the mechanism of Huganning tablet (HGNP) in the treatment of nonalcoholic fatty liver disease (NAFLD) based on network pharmacology and computer-aided drug design. Firstly, the potential ingredients and targets of HGNP were identified from TCMSP database, Swiss Target Prediction database, Chinese pharmacopoeia (2015) and literatures, and then the targets of HGNP intersected with NAFLD disease targets that obtained in GeneCards database to acquired potential targets. The bioconductor bioinformatics package of R software was used for gene ontology (GO) enrichment and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. The network of “potential ingredient-key target-pathway” was formed in Cytoscape software to study the interactions between potential ingredients of HGNP, key targets, pathways and NAFLD. Based on the results of network pharmacology, the molecular docking analysis of the key targets and potential active ingredients in HGNP tablets with top degree in the network was conducted using Discovery Studio 2020 software, followed by molecular dynamics simulations, binding free energy calculation, drug-likeness properties analysis and ADMET (absorption, distribution, metabolism, excretion and toxicity) properties prediction. In vitro, HepG2 cells were used to establish steatosis model, and the effects of five key compounds on hepatocyte steatosis were analyzed by oil red O staining and triglyceride (TG) content determination. The results showed that 141 ingredients and 151 potential targets were obtained. A total of 2 526 items and 151 pathways were identified by GO and KEGG enrichment analysis. The molecular docking suggested that five components, isorhamnetin, salvianolic acid B, emodin, resveratrol and rhein, exhibited strong binding ability with key targets [retinoic acid receptor RXR-alpha (RXRA), tumor necrosis factor (TNF), glycogen synthase kinase-3 beta (GSK3B), serine/threonine-protein kinase 1 (AKT1)]. It was further verified that isorhamnetin and salvianolic acid B bind to key targets with good structural stability and binding affinity based on molecular dynamics simulations and binding free energy calculations. The drug-likeness properties, pharmacokinetic properties and toxicity of five key compounds were more comprehensively analyzed through drug-likeness properties analysis and ADMET properties prediction. In vitro, all five compounds, isorhamnetin, salvianolic acid B, emodin, resveratrol, and rhein, improved hepatocyte steatosis of HepG2 cells, confirming the reliability of the present study. In conclusion, based on network pharmacology, computer-aided drug design and in vitro validation, this study investigated the mechanism of HGNP for the treatment of NAFLD at multiple levels and provided a basis for its clinical application.

OBJECTIVETo examine the changes of expressions of orexin A, orexin receptor-1 (OX1R), prepro-orexin (Prepro-OX) mRNA, OX1R mRNA and ob-R of hypothalamus in rats with chronic renal failure (CRF).

METHODSSixty-two male Wister rats weighing 200-250 g were divided into three groups, including group 1 (normal, n = 5), group 2 (sham-operated, n = 25) and group 3 (CRF, n = 32). Hypothalamus orexin A was assayed by radioimmunoassay. Serum leptin was assayed by enzyme linked immunosorbent assay. The expression of Prepro-OX mRNA and OX1R mRNA of hypothalamus were measured by reverse transcription polymerase chain reaction, and expression of orexin A, OX1R and ob-R by immunohistochemistry. Automatic biochemical analyzer was used to measure the serum creatinine.

RESULTSHypothalamus orexin A levels were negatively correlated (r = -0.63, P < 0.001) with serum leptin levels in the rats. The expression of hypothalamus Prepro-OX mRNA in CRF rats was significantly lower than that of sham-operation at week 12 (P < 0.01). Hypothalamus Prepro-OX mRNA levels were negatively correlated (r = -0.81, P < 0.001) with the levels of serum leptin and serum creatinine (r = -0.68, P < 0.05) in the rats at week 12. The expression of hypothalamus OX1R mRNA in CRF rats was lower than that of sham-operation at week 12 (P > 0.05). Specific immunoreactivity for orexin A was present in perikeryon of the hypothalamus neuron. Specific OX1R-like immunoreactivity was observed in some nerve fibres. Specific immunoreactivity for ob-R was present in membranes of the hypothalamus neuron. Hypothalamus neurons of orexin A-like specific immunoreactivity in CRF rats were significantly fewer than those in shamoperated rats at week 8. Hypothalamus neurons of OX1R-like specific immunoreactivity in CRF rats were similar to those in sham-operated rat at week 8. Hypothalamus neurons of ob-R-like specific immunoreactivity in CRF rats were significantly more than those in sham-operated rats at week 8.

CONCLUSIONSThe lower hypothalamus orexin A levels may be induced by high serum leptin level in CRF rats. The lower expression of hypothalamus Prepro-OX mRNA in CRF rats may be one of the main causes inducing lower hypothalamus orexin A. The expression of OX1R in hypothalamus neurons is somewhat reduced and the expression of ob-R in hypothalamus neurons is somewhat raised in CRF rats. These remain to be studied further.

OBJECTIVETo explore the application value of morphology assessment of sperm from fresh semen in routine in vitro fertilization (IVF).

METHODSWe analyzed the morphology of the sperm from fresh or optimized semen samples and, based on the sperm morphology of the raw semen, allocated 908 IVF cycles due to the pure tubal factor to different groups: morphologically normal sperm (MNS) ≤ 4%, > 4% - ≤ 15%, and > 15% in Trial 1 and MNS ≤ 1%, > 1% - ≤ 2%, > 2% - ≤ 3%, and > 3%-- ≤ 4% in Trial 2. We compared the rates of fertilization, cleavage, high-quality embryo, -blastocyst formation, and pregnancy among different groups.

RESULTSThe total fertilization rate was significantly lower in the MNS ≤ 4% than in the MNS > 4% - ≤ 15% and >15% groups (74.40% vs 78.61% and 80.03%, P < 0.01). Compared with the MNS ≤ 1%, > 1% - ≤ 2%, and > 2% - ≤ 3% groups, the MNS > 3% - ≤ 4% group showed remarkably increased rates of 2PN normal fertilization (77.23%, 78.97% and 78.99% vs 85.47%, P < 0.01), cleavage (95.71%, 96.01% and 97.27% vs 98.73%, P < 0.05), and blastocyst formation (53.85%, 49.01% and 49.55% vs 63.41%, P < 0.01). No statistically significant differences were observed in the rates of clinical pregnancy, implantation, early abortion, live birth, or malformation at birth among different groups (P > 0.05).

CONCLUSIONMNS ≤ 4% affected the total rate of fertilization while MNS ≤ 3% reduced the rate of normal fertilization in IVF. However, even MNS ≤ 1% did not result in fertilization disorder or failure. Therefore, teratozoospermia alone was not an indicator of ICSI and sperm mor- phology assessment had no obvious value for predicting the rates of embryo quality, clinical pregnancy, and live birth in IVF.
