1.Oral cavity delivery system of unfractionated and low molecular weight heparin.
Acta Pharmaceutica Sinica 2010;45(10):1317-21
The difference between absorption of unfractionated heparin (UFH) and low molecular weight heparin (LMWH) after oral and oral cavity administration were studied respectively, and the compatible enhancer for oral cavity delivery system of both drugs was found. The LMWH and UFH films were prepared with two bioadhesive materials Carbopol and alginate sodium for oral cavity delivery. The activated partial thromboplastin time (APTT) was used to determine LMWH and UFH in plasma after oral, oral cavity and sc administration in rats. The results show that the enhancer (Labrasol) can increase the absorption of LMWH and UFH through oral cavity in rats but not obviously. The oral cavity iontophoretic delivery system is a useful method to improve the absorption of LMWH and UFH through oral cavity mucosa.

Objective To analyze the anatomic factors of the central retinal artery occlusion or the ophthalmic artery occlusion after the injection of facial cosmetic surgery.Methods Retrospectively analyzed 3 patients who occurred severely ocular complications just after facial cosmetic injection in last 2 years.The diagnosis of central retinal artery occlusion was confirmed by fundus examination and fundus fluoresce-in angiography.Analysis the blood vessel distribution of the injection site and characteristics of peri-orbit vascular anastomosis.Results All the 3 cases presented no light perception,with eye pain or (and)the eyeball pain.The fundus test and fundus fluorescein angiographies showed central retinal artery obstruction.Facial cosmetic injection pressure significantly exceeded the ophthalmic artery systolic pressure 2 seconds after injection (P <0.05).Dorsal nasal artery and angular artery were anastomotic,and the angular artery was usually anastomotic with lateral nasal branches of the posterior ciliary artery.The filler can enter the ophthalmic artery by the branches of the anastomosis,which can make ophthalmic artery occlusion,central retinal artery occlusion or get occlusion of their branches.Conclusion The injectant may get into the orbital artery and retrograde to the ophthalmic artery,which resulting in ophthalmic artery occlusion,or get into central retinal artery and posterior ciliary artery,which resulting in serious ocular complications.

Objectives To investigate preparation of gemcitabine albumin nanoparticles, and its property of slow-release, the cytotoxic effect on pancreatic cancer cells (PANC1) in vitro, for improving the effect of regional intra-arterial infusion chemotherapy in pancreatic cancer with new medicament in the future. Methods The gemcitabine albumin nanoparticles were prepared with bovine serum albumin and gemcitabine with the desolvation-crosslink method, the concentration of gemcitabine was detected by high performance liquid chromatography (HPLC). The cytotoxic effect on pancreatic cancer cells in vitro were detected with MTT colorimetric assay. Results The mean diameter of gemcitabine albumin nanoparticles was (156.2±2.2) nm, and Zeta potential was (-20.4±1.41)mV, drug loading was 10.8%, drug release time in virto was 3 hours respectively. Gemcitabine albumin nanoparticles (0.01~50 μg/ml) had a 31%~44% inhibitory rate on PANC1 cell, which was similar to the inhibitory rate of same concentration of gemcitabine (26%~47%). Conclusions The new preparation of gemcitabine albumin nanoparticles had obvious drug slow-release effect, which may help improve the effect of regional intra-arterial infusion chemotherapy for pancreatic cancer.

Objective To investigate the prognostic value of CDKN2A mRNA in glioblastoma (GBM).Methods CDKN2A gene mRNA data were obtained from three different GBM database online (TCGA,REMBARNDT and GSE16011).The correlations between overall survival (OS) and CDKN2A expression were analyzed by Kaplan-Meier method and multivariate Cox regression analysis.Results In the TCGA database (n =358),patients with high CDKN2A mRNA level got longer OS than those with low expression level [median OS:18.0 months (95 % CI 15.0-21.0 months) vs 13.9 months (95 % CI 12.4-15.4 months),P =0.001].In another two validation datasets,patients with high CDKN2A mRNA level had longer OS than those with low expression level [median OS in REMBRANT:16.6 months (95 % CI 13.3-19.8 months) vs 11.8 months (95 % CI 7.3-16.4 months),P =0.019; in GSE16011:11.9 months (95 % CI 8.3-15.6 months) vs 8.4 months (95 % CI 6.2-10.5 months),P =0.005].CDKN2A mRNA level was an independent prognostic factor for GBM.The combination of CDKN2A mRNA expression with MGMT promoter methylation status or G-CIMP status/IDH1 mutations provided an optimized prognostic factor in GBM patients.Conclusion The CDKN2A mRNA has prognostic value in GBM patients,which provided an optimized stratification strategy based on multiple biomarkers.

Objective:To investigate the effect of HSM on the immunoreaction and renal fibrosis in mice with cecal ligation and puncture (CLP).Methods: Renal fibrosis was induced by CLP;mice were divided into three groups,including sham group (sham,n =5),model group (CLP,n =11),therapy group (HSM,n =11).HSM extract [200 mg/(kg?d)] was orally administered to HSM group2 hour before surgery and repeated everyday throughout 10 days,while sham group and model group were given the same dose of normalsaline.FACS assay was used to analyze the amount of macrophages ,neutrophils and Treg in PBMC,as well as macrophages in peritonealfluid;we used Q-PCR assay to analyze the expression of inflammatory molecules (IL-1βand TNF-α) and fibrogenic cytokines (TGF-β,MMP9 and TIMP1) from renal sections.Besides,renal sections were subjected to HE stain and immunohistochemical staining with α-SMA and fibronectin.Results: The amount of model group′s macrophages and neutrophils in PBMC,as well as macrophages in theperitoneal fluid were significantly higher than sham group ′s,whereas HSM succeeded in lowering them;contrast to sham group,Tregs′amount of CLP group and HSM group in PBMC had no significant changes .The expression of inflammatory molecules (IL-1βand TNF-α) and fibrogenic cytokines (TGF-β,MMP9 and TIMP1) from CLP group′s renal sections were remarkably improved ,whereas HSM inhibitedthat.The CLP group′s HE results showed obvious renal inflammatory damage ,whereas HSM reduced the histopathologicalterations;contrast to sham group,model group′s expression of α-SMA and fibronectin was remarkably improved,while HSM groupshowed lower expression.Conclusion: HSM extract could regulate immunity response and had effect in improving renal fibrosis .
