AIM: To study the preparation and physiological compatibility of pulmonary administration with Saponius of Panax Notoginseng (PNS) liposomes. METHODS: PNS liposomes was prepared by thin film dispersion method. The prefered formulation was determined by factorial design. Ciliary movement in situtoad palate model and the changes of pulmonary edema index and pathology of lungs in rats were investigated to evaluate the physiological compatibility of PNS liposomes. RESULTS: PNS liposomes were proved to be large unilamellar vesicle (LUV) liposomes with spherical shape .The liposomes composed of PC and Ch has a high PNS capture efficiency of 78.5% ?2.15% . The mean vesicle size of liposomes were 1546.5nm ?321.4nm which were quite homogeneous in size distribution. The lasting time of ciliary movement after the rinsing of PNS liposomes was the 92.14% of the effect of PBS buffer. The pulmonary edema index and pathological changes of lung tissue in PNS liposomes group were significantly different from those in PNS solution group and close to those in PBS buffer group. CONCLUSION: PNS liposomes has good physiological compatibility with promising market development and application.

Object To prepare Panax notoginseng saponin (PNS) liposomes and investigate their characterization of pharmaceutics and pulmonary pharmacokinetics in rats. Methods The film-disperion method was used to prepare PNS liposomes by investigating its form, vesicle size, entrapping efficiency and stability. The study of pulmonary pharmacokinetics in rats was carried out by pulmonary instillation. Results The entrapment of PNS liposomes was 78.50%. The mean vesicle size was 1.5 ?m with uniform externality. The drug leakage from PNS liposomes was slow. Low temperature was required for its storage. The pulmonary pharmacokinetics parameters were as follows: T 1/2 ?=7.00 h, T 1/2 ?=27.72 h, AUC= 2 218.9 ?g?h/mL, the absolute bioavailability was 70.14%. Conclusion PNS liposomes with high entrapment and stability can prolong its circulation in blood and improve the PNS bioavailability via lung approach.

Aim To investigate the effects of cajanonic acid A (CAA) on lipid metabolism in murine 3T3-L1 adipocytes. Methods 3T3-L1 cells induced to differ-entiated into mature adipocytes were treated with CAA in different dosages for 48 h, then total lipids as well as triglyceride, free fatty acid and glycerol were meas-ured. The expression levels of genes related to lipid metabolism were quantitatively analyzed by real-time fluorescent quantitative polymearase chain reaction ( RTFQ-PCR) . Results Total lipids and triglyceride in 3T3-L1 adipocytes were markedly reduced by CAA. The release of free fatty acid and glycerol was lower than that of control. This coincided with decreased mRNA levels of the key enzymes involved in de novo lipogenesis ( acetyl CoA carboxylase and fatty acid syn-thase) , fatty acid uptake ( lipoprotein lipase) , and li-polysis ( hormone sensitive lipase and adipose triglycer-ide lipase ) . While the expression of fatty acid oxida-tive genes including acyl CoA oxidase and carnitine palmitoyl transferase1 was increased after CAA treat-ment. Conclusion CAA may inhibit lipogenesis and lipolysis,reduce circulating free fatty acid and improve the lipid metabolism in adipocytes by regulating gene expressions.

Objective:To investigate the value of serum anti-PLA2 R as a diagnostic marker of idiopathic membranous nephropathy( IMN).Methods:All available articles about serum anti-PLA2 R as a marker of IMN which were published at home and abroad from 2009.1 to 2013.12 were pooled from the databases of PubMed,Elsevier,Springer,CNKI,VIP and Wanfang database et al. The quality of the papers were evaluated by the quality assessment for studies of diagnostic accuracy studies( QUADAS).And then a meta-analysis was conducted by the statistical softwares of Meta-Disc and Stata.The diagnostic value of serum anti-PLA2 R in IMN was evaluated by the statistical indicators of pooled sensitivity, pooled specificity, pooled likelihood ratio and summary receiver operating characteristic curve( ROC curve).Sensitivity analysis was performed by reducing a paper in order,and publication bias was tested by Egger funnel plot.Results: Seven articles were selected to the meta-analysis according to the inclusion criteria and 967 cases were included in the study ( 454 IMN patients and 513 controls ).Heterogeneity test showed no heterogeneity threshold effect ( Spearman correlation coefficient was 0.107,P=0.819),but there was heterogeneity caused by non threshold effects(Cochrane-Q was 16.89,P=0.009 7).So random model was used to pool the effect size.The overall combined effect sizes:sensitivity was 69%,95%CI:0.65-0.73;specificity:98%,95%CI:0.96-0.99;pooled positive likelihood ratio 16.37,95%CI:4.06-65.95;pooled negative likelihood ratio 0.32,95%CI:0.24-0.43;AUC of SROC:0.854 0,Q*=0.785 0.Sensitivity analysis showed that this research was stable and reliable and Egger funnel plot showed little publication bias.Conclusion: Serum anti-PLA2 R is an useful biomarker to the diagnosis of IMN.

Objective To explore the impact of preoperative neoadjuvant chemotherapy on the expressions of multi-drug resistance genes in patients with cervical cancer and its relationship with the effect of chemotherapy. Methods Ninety-eight cervical cancer patients with TP regimen selected to perform preoperative chemotherapy were enrolled in the Affiliated Hospital of Guiyang Medical College between January 2010 and June 2014. Immunohistochemisty (En vision method) was used to determine the expressions of P-gP, GST-π and TopoII of the same patients before and after neoadjuvant chemotherapy and explore the relationship with the effect of chemotherapy. Results The positive expression rates of P-gp and GST-π were 71.43% and 64.29% before chemotherapy and 80.61%and 74.49%after chemotherapy, respectively. The former two had significant differences (P<0.01). The positive expression rates of TopoII was 48.98%before chemotherapy and 28.57%after chemotherapy , respectively, showing significant differences (P < 0.01). The expressions of P-gp, GST-π and TopoⅡ gene were not affected by the clinical and pathological features of cervical cancer (P > 0.05). Before neoadjuvant chemotherapy, the positive expression of GST-π in the ineffective group was statistically higher than that in the effective group (P<0.05). The positive expressions of P-gp and Topo II showed no statistical significance between the effective group and the ineffective group (P > 0.05). There was significant correlation in the expressions of P-gp, GST-π and TopoⅡ(P < 0.05) before and after neoadjuvant chemotherapy. Conclusions The expression of P-gp, GST-πand TopoⅡgene may not be affected by the clinical and pathological features of cervical cancer, but may change expressions of multi-drug resistance genes in cervical cancer by neoadjuvant chemotherapy. Monitoring their expression has a guiding significance for drug selection, prognostic judgment, and the following treatment regimen decision. The GST-π, expression level can be used as a biological parameter to predict the effect of TP regimen neoadjuvant chemotherapy.

Weight gain, skinfold thickness, circumference and body density were measured in 30 primiparous women aged from. 23-31 years (averaged 26.3 years old).The average body weight gained 13kg from 6 to 37 weeks of pregnancy.The suprailiac skinfold thickness in 24-37 weeks and the subscapular skinfold thickness in 37 weeks increased significantly from the 6th week of pregnancy, but the triceps and biceps skinfold thickness did not change significantly. The density of the body in 24th and 37th week of pregnancy decreased significantly.The change and the body fat (%) calculated by means of 4 skinfolds increased in 3.7% (5.7kg of fat). The mean values of the hip circumference in 24th and 37th week were significantly different from that in 6th week of pregnancy. The upper thigh in the 24th and 37th week also increased slightly but not significantly different as compared with the 6th week. The mean values of arm, mid-thigh and calf circumference did not change during pregnancy.
