OBJECTIVETo assess the effect of endostatin on growth and neoplastic angiogenesis in transplanted human lung adenocarcinoma Calu-6 tumor in nude mice.

METHODSTo treat Calu-6 tumor-bearing mice with endostatin at different doses, and to record the changes of the tumor size. The expressions of survivin, VEGF, COX-2 and MVD in tumor tissue were examined by immunohistochemistry staining, circulating endothelial cells (CECs) by flow cytometry and mRNA of CD146 and CD105 by RT-PCR and real-time PCR.

RESULTSAfter endostatin treatment, the tumor size was conspicuously shrunk, and the expressions of survivin, COX-2 and VEGF protein and MVD in tumor tissue decreased concomitantly with the significant difference between each of trial groups and control group (all P < 0.05). Both CECs and mRNA of CD146 and CD105 diminished remarkably. A positive correlation between both exhibition and change of amount of activated CECs and survivin, VEGF expression and MVD count in tumor tissue was found.

CONCLUSIONEndostatin can decrease the expression of survivin, COX-2, VEGF and MVD, and to inhibit the growth of transplanted tumor. Activated CECs may probably serve as an ideal marker to predict the efficacy and prognosis of anti-angiogenesis therapy.

Objective To establish a comprehensive method combining physical model experiment and numerical simulation for studying airflow state of upper respiratory tract. Methods Based on CT medical images published online, a three-dimensional (3D) model of human upper respiratory tract was reconstructed. Based on 3D printing technology, an experimental model of the upper respiratory tract was established and the flow process of respiration was measured. A numerical simulation model was created based on the meshing of upper respiratory tract model and the turbulent Realizable k-ε model. Results Firstly, the result of numerical simulation was compared with the experimental conditions, and good agreement was achieved. The numerical simulation results showed that the airflow in respiratory process was in a parabolic shape; the distribution of flow field, pressure on wall and vortex structure were different between inspiratory and expiratory phases; there were air residues in the upper and lower nasal passages during the respiratory exchange process. In addition, the effects of airflow on physiological environment of the upper respiratory tract were preliminarily analyzed through the steak line, pressure field and vortex structure distribution. Conclusions The method proposed in this paper has the characteristics of pertinence, rapidity and accuracy, which gives full play to the advantages of reliable physical experiments and fine numerical simulation, and is applicable for studying different problems of the upper respiratory tract in different cases, with a high value for personalized diagnosis and treatment in clinic.

OBJECTIVE: To observe the effects of acupuncture on neurologic function and serum inflammatory factors in patients after thrombolysis in acute ischemic stroke (AIS). METHODS: A total of 102 AIS patients with onset to treatment time (OTT) ≤3 h were randomly divided into an observation group and a control group, 51 cases each group. In the control group, thrombolysis and conventional medical treatment were applied. On the basis of the treatment as the control group, acupuncture at Shuigou (GV 26), Zhongwan (CV 12), Qihai (CV 6), Neiguan (PC 6), etc. was applied in the observation group, 30 min each time, once a day. Both groups were treated for 2 weeks. Before and after treatment, the scores of National Institutes of Health stroke scale (NIHSS), modified Rankin scale (mRS), modified Barthel index (MBI) and serum level of homocysteine (Hcy), hypersensitive C-reactive protein (hs-CRP) were compared, and the clinical efficacy was evaluated in the two groups. RESULTS: After treatment, the scores of NIHSS, mRS and serum level of Hcy, hs-CRP were decreased compared with those before treatment (P<0.05), while the MBI scores were increased (P<0.05) in the two groups. The scores of NIHSS, mRS and serum level of Hcy, hs-CRP in the observation group were lower than those in the control group (P<0.05, P<0.01), the MBI score in the observation group was higher than that in the control group (P<0.01). The total effective rate was 88.2% (45/51) in the observation group, which was superior to 70.6% (36/51) in the control group (P<0.05). CONCLUSION Acupuncture could promote the recovery of neurologic function in patients after thrombolysis in AIS, improve the ability of daily living, which may be related to reducing the level of inflammatory factors, thus inhibiting inflammatory response and improving cerebral ischemia reperfusion injury.

Objective: To evaluate the safety, efficacy and tolerability of China-made sildenafil citrate (Jinge) in the treatment of ED. METHODS: We conducted a multi-center, randomized, double-blind and placebo-controlled clinical trial among 222 ED patients in five urological or andrological clinics of China. The patients were randomly assigned to receive sildenafil citrate (SC, n = 111) or placebo (n = 111) for 8 weeks. We obtained and analyzed the demographic and clinical characteristics of the patients, the scores of International Index of Erectile Function (IIEF), the success rate of sexual intercourse, and the incidence of adverse events. RESULTS: No statistically significant differences were found between the patients of the SC and those of the placebo group in the mean age (［47.2±11.32］ yr vs ［46.67±13.08］ yr, P>0.05), psychological etiology (27.93% vs 23.42%, P>0.05), organic etiology (21.62% vs 29.73%, P>0.05) or mixed etiology (50.45% vs 46.85%, P>0.05), nor in height, weight, nationality, or history of smoking, drinking or allergy. Compared with the placebo controls, the SC-treated patients showed significant increases in the excellence rate of effectiveness (29.91% vs 78.90%, P<0.01), success rate of sexual intercourse (29.16% vs 63.87%, P<0.01), and total effectiveness rate (34.58% vs 77.98%, P<0.01). The effectiveness rates on organic, psychogenic and mixed types ED were remarkably higher in the SC group (64.52%, 83.33%, and 82.14%) than in the placebo control (46.15%, 21.21%, and 25.00%) (P<0.01). Mild or temporary adverse events were observed in 32 cases in the SC group as compared with 13 in the placebo control. CONCLUSIONS China-made sildenafil citrate is an effective, safe and well-tolerated drug for ED of different etiologies in the Chinese population.

Farnesyl diphosphate synthase(FPPS) is a key enzyme at the branch point of the sesquiterpene biosynthetic pathway, but there are no reports on the transcriptional regulation of FPPS promoter in Pogostemon cabin. In the early stage of this study, we obtained the binding protein PcFBA-1 of FPPS gene promoter in P. cabin. In order to explore the possible mechanism of PcFBA-1 involved in the regulation of patchouli alcohol biosynthesis, this study performed PCR-based cloning and sequencing analysis of PcFBA-1, analyzed the expression patterns of PcFBA-1 in different tissues by fluorescence quantitative PCR and its subcellular localization using the protoplast transformation system, detected the binding of PcFBA-1 protein to the FPPS promoter in vitro with the yeast one-hybrid system, and verified its transcriptional regulatory function by dual-luciferase reporter gene assay. The findings demonstrated that the cloned PcFBA-1 had an open reading frame(ORF) of 1 131 bp, encoding a protein of 376 amino acids, containing two conserved domains named F-box-like superfamily and FBA-1 superfamily, and belonging to the F-box family. Moreover, neither signal peptide nor transmembrane domain was contained, implying that it was an unstable hydrophilic protein. In addition, as revealed by fluorescence quantitative PCR results, PcFBA-1 had the highest expression in leaves, and there was no significant difference in expression in roots or stems. PcFBA-1 protein was proved mainly located in the cytoplasm. Furthermore, yeast one-hybrid screening and dual-luciferase reporter gene assay showed that PcFBA-1 was able to bind to FPPS promoter both in vitro and in vivo to enhance the activity of FPPS promoter. In summary, this study identifies a new transcription factor PcFBA-1 in P. cabin, which directly binds to the FPPS gene promoter to enhance the promoter activity. This had laid a foundation for the biosynthesis of patchouli alcohol and other active ingre-dients and provided a basis for metabolic engineering and genetic improvement of P. cabin.
