High-speed counter-current chromatography (HSCCC) was used to high performance separate and prepare lignans from Schisandrae chinensis fructus. The solvent system is composed of n-hexane-ethyl acetate-methanol-water (9 : 1 : 5 : 5) and n-hexane-ethyl acetate-methanol-water (9 : 1 : 9 : 5), speed is at 900 r.min-1, and flow rate is at 2.0 mL.min-1. Five fractions from Schisandrae chinensis fructus extract were separated and prepared with one HSCCC process. They were identified as schisandrin, gomisin J, schisandrol B, schisantherin A and deoxyschizandrin by electrospray ionization-multiple tandem mass spectrometry (ESI-MSn), respectively. Their contents were obtained in 98.74%, 94.32%, 99.53%, 94.23% and 98.68% by ultra high performance liquid chromatography (UPLC), separately. The rapid and simple method can be applied for the preparation of lignans from Schisandrae chinensis fructus.

The dialysis method was employed to prepare blank and doxorubicin (DOX) loaded micelles formed by temperature- and pH- sensitive polyhistidine-co-polyDL-lactide-co-glycolide-co-polyethyleneglycol-co-polyDL-lactide-co-glycolide-co-polyhistidine (PHis-b-PLGA-b-PEG-b-PLGA-b-PHis). The critical micelle concentrations (CMC) of the copolymers were measured with Pyrene Fluorescent Probe Technique. The temperature- and pH- sensitive properties of the blank micelles solution were investigated by optical transmittance measurement. The morphology and diameter of DOX micelles were characterized by transmission electron microscopy (TEM) and dynamic light scattering (DLS). The entrapment rate and drug-loading rate were determined with dialysis method. The in vitro release study was further performed to examine the temperature- and pH-responsive drug release behavior from DOX-loaded micelles. The results indicated that the CMC, entrapment efficiency and drug-loaded amount of the micelles were 7.5 x 10(-3) g x L(-1), 85.2 +/- 3.1% and 10.4 +/- 4.5%, respectively. The DOX micelle was globular-shaped with a mean diameter of 91.1 +/- 15.8 nm. The transmittance of micelle solution consistently increased with the increasing temperature or decreasing pH. In comparison to the drug release profile at physiological conditions (37 degrees C, pH 7.4), the DOX-loaded micelles showed faster drug release rate at higher temperature (41 degrees C), lower pH (pH 7.0, pH 6.5, pH 5.0) or higher temperature and lower pH (41 degrees C, pH 5.0). This indicated that the micelles showed a temperature and pH-triggered drug release pattern. Base on the above results, it can be concluded that PHis-b-PLGA-b-PEG-b-PLGA-b-PHis block copolymer micelles which respond to temperature and pH stimuli are promising smart carriers for anti-tumor drugs with the advantages of temperature- and pH- triggered drug release.

OBJECTIVE:To provide reference for rational drug use in the clinic. METHODS:Irrational medication orders eval-uated by the Affiliated Cancer Hospital of Zhengzhou University during Oct. 2014 to Sep. 2015 were arrangemented,summarized and analyzed. RESULTS:A total of 515 inpatient medical records were reviewed and analyzed,among which there were 165 unrea-sonable medical records and 185 irrational medication orders. Irrational medical records of general surgery department were the most(38 items,accounting for 23.03%). Irrational drug use mainly included irrational usage and dosage(80.00%),drug use with-out indications or not suit indications (7.57%),inappropriate solvent selection (4.86%). Including 66.22% of single overdose, 18.92% of longer medication duration. CONCLUSIONS:There are many irrational medical orders which should be standardized in our hospital,especially overdose and longer medication duration,which increase financial burden of patient. Pharmacists should strengthen communication with clinicians,and hold rational drug use trainings regularly base on the types of the irrationality. These can help to improve rational drug use and guarantee the safety of drug use.

Objective To evaluate the therapeutic efficiency of reversed lamellar keratoplasty for bullous keratopathy, Terrien's marginal degeneration and ocular chemical burns.Methods Twenty eyes of patients with bullous keratopathy, twelve eyes with Terrien's marginal degeneration, ten eyes with chemical burns were recruited in this study.Diseased tissues were removed by means of dissection.Reversed lamellae corneal tissues which had been prepared by cryopreservation were thawed and rinsed. Then the prepared posterior corneal lamellae was turned over, endothelium facing upwards. The diameter of the graft should be 0.5~1.0mm larger than that of the recipient bed. The reversed donor posterior lamellae was sutured into the host keratectomy bed with 10-0 nylon sutures continuously or interruptedly.Results Allograft reaction episode occurred only one (chemical burn) of the total 42 eyes enrolled.The grafts of the rest 41 eyes maintained clear or semitransparent for 1~5 years. Graft edema could be observed within 2~4 weeks postoperatively. Postoperative interface separation was not found. For all 20 patients with bullous keratopathy, the symptoms of pain disappeared. The visual acuity improved 2~3 lines of Snellen among eleven of twelve patients with Terrien's marginal degeneration. The visual acuity improved 2~3 lines of Snellen with four patients with chemical burns.Conclusion The technique of reversed lamellar keratoplasty can be applied successfully for tectonic reconstruction of corneal surface such as bullous keratopathy, Terrien' s marginal degeneration and also chemical burns.The effects of therapy was satisfactory.
