The morphological indexes of the Scuophularia ningpoensis seedlings including the longth, diameter and weight were measured, clustering analysis was used to set up the standard quality grading of seedlings of S. Ningpoensis by SPSS. Field experiment was carried out to measure the indicators of plants growth and development, the yield and the quality. The results showed that the growth and yield of class I seedlings were better than those of class II and III. The content of main active ingredients was affected barely by seedlings classification. To ensure the quality, class II seedlings or above should be used for plantation. The established quality classification standard of S. ningpoensis seedlings was scientific and feasible, and provides the basis for the standardized cultivation of S. ningpoensis.

Objective To analyze the epidemiological characteristics of the imported malaria cases in 20 counties at the bor?der region of Yunnan Province from 2012 to 2014,so as to provide the evidence?based proof for adjusting the strategies in the elimination stage. Methods The malaria epidemic data of the 20 border counties in Yunnan Province from 2012 to 2014 were collected and analyzed by using Microsoft Excel 2010. Results From 2012 to 2014,a total of 1 558 malaria cases were report?ed in the 20 border counties in Yunnan Province,among which,1 336 were imported cases,accounting for 85.75%(1 336/1 558),and 222 were indigenous cases,accounting for 14.25%(222/1 558). The number of the imported cases in the above years took up 80.00%(544/680),89.10%(425/477)and 91.52%(367/401)of the total reported cases in the whole year,re?spectively. Among all the 1 336 imported cases,1 045(78.22%)were infected with Plasmodium vivax,284(21.26%)were in?fected with P. falciparum,3 were infected with P. malariae,3 were mixed infection and 1 was an unclassified case;2 patients died. And 95.58%of the cases were mainly infected in Myanmar(1 277 cases). Young and middle?aged adult of 20-40 years who worked overseas were the predominant(802 cases,60.03%)and most of the cases occurred from April to June of the year (679 cases,50.82%). Those cases mainly distributed in Tengchong(459 cases),Ruili(366 cases),Yingjiang(191 cases)and Mangshi(78 cases). Conclusions The epidemic situation of imported malaria is serious in the border region of Yunnan Prov?ince. Therefore,the surveillance system of malaria control needs to be well planned and managed to ensure timely case detection and prompt response at the elimination and post?elimination stage.

Bicyclol with benzyl alcohol structure, is a poorly water-soluble drug, used for the treatment of chronic hepatitis B. To increase the drug solubility and oral bioavailability, a Bicyclol-phospholipid complex was studied on its preparation, formation mechanism, and the influence on drug physicochemical properties and oral absorption. The complex was prepared by a solvent evaporation method. The optimal formulation was selected by orthogonal experimental design, and a reasonable evaluating method of the complexation rate was established. Various methods, such as differential scanning calorimetry (DSC), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and 31P nuclear magnetic resonance (31P-NMR), were used to explore the phase state and formation mechanism of the complex. The solubility of drug in complex was investigated in water/n-octanol. Preliminary study of its absorption and liver tissue distribution in rats was also carried out. The results showed that Bicyclol and phosphatidylcholine can be complexed entirely in the molar ratio 1 : 2. Bicyclol was dispersed in phospholipids as amorphous state. They were combined by intermolecular hydrogen bond due to charge transfer effect which occurred between the two polarities of the double bond between phosphorus and oxygen (P=O) of phosphatidylcholine and benzalcohol group of Bicyclol. The solubility of the complex compared to the active pharmaceutical ingredient (API) was effectively enhanced 5.75 times in water and 7.72 times in n-octanol, separately. In addition, drug concentrations were also enhanced 43 times in plasma and 13 times in liver with one hour after administering the complex to rats via oral gavage. All of these indicated that Bicyclol with benzalcohol group can interact with phospholipids to form complex, improving drug's physicochemical properties, thus further increasing its absorption and target tissue distribution. This study also provided theoretical reference for the research of other benzalcohol derivatives complexed with phospholipids.

Injectable lipid emulsions have been routinely used in patients since 1960s as a nutritional supplement for patients requiring parenteral nutrition. In recent years, lipid injectable emulsions have been extensively studied as a kind of novel drug carrier, also the quality problems of the lipid emulsion attract more and more attentions gradually. Large diameter tail of injectable lipid emulsions as a significant quality control indicator should pay more attention. Regarding to the defect of detecting large diameter tail of lipid injectable emulsions in our country, the purpose of this article is to summarize the techniques of detecting large diameter tail, illustrate the impacts of large lipid droplet on the quality of lipid injectable emulsions, emphasize the importance of detecting large diameter tail in lipid emulsions and provide guidance for researching and developing lipid emulsions in domestic market.

Objective To evaluate the results of rotary self-locking intramedullary nail (RSIN) for treating long tubular bone fracture of extremities, and discuss the current problems. Methods One hundred and twenty-two patients with long tubular bone fracture of extremities,including 59 femoral fractures,57 tibial fractures and 6 humeral fractures,who had been treated by RSIN were retrospectively investigated. Results All of the patients achieved clin-ical healing,with an average time of 24 weeks. Nobody was found to appear maluniun,infection and the break of inter-nal fixture. Internal fixations were removed after the fracture healing,with an average time of 14 months. It was diffi-cult to remove the internal fixations in 5 cases, and one case refractured after removing the internal fixations. Conclu-sion RSIN has the advantages such as easy operation,less trauma,no pendulum effect,early motion after operation and so on, except the characters of general interlocking intramedullary nail such as anti-rotation, anti-crispition and anti-displacement.

OBJECTIVETo explore the effect of Bushen Huoxue Compound (BHC) on lactate dehydrogenase (LDH) leakage, expressions of vascular endothelial growth factor (VEGF) and VEGF mRNA in retinal Muller cells under high glucose condition or advanced glycosylation end products (AGEs) condition by using serum pharmacological method.

METHODSThe retinal Müller cells of 5-7 days post-natal Sprague Dawley (SD) rats were cultured with modified enzyme-digestion method. Purified retinal Muller cells were cultured in normal conditions, high glucose condition (50 mmol/L) or AGEs (50 mg/L and 100 mg/L) conditions, and BHC-containing serum was added to culture medium. The LDH leakage and VEGF expressions were measured by enzyme-linked immunosorbent assay (ELISA). In addition, the relative expression of VEGF mRNA was tested by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSCompared with the normal control group, expressions of VEGF and VEGF mRNA were significantly increased in the high glucose group, the low dose AGEs group and the high dose AGEs group (all P < 0.01). The LDH leakage was obviously increased in the high dose AGEs group, when compared with the normal control group and the high glucose group (P < 0.01). The LDH leakage, expressions of VEGF and VEGF mRNA were obviously decreased by BHC-containing serum both in high glucose and AGEs conditions (P < 0.05, P < 0.01). BHC-containing serum had no significant effect on the LDH leakage and expressions of VEGF and VEGF mRNA in normal conditions (P > 0.05).

CONCLUSIONSAGEs intervention could obviously lower the stability of Müller cell membrane. Up-regulated expressions of VEGF and VEGF mRNA in cultured Müller cells could be induced by AGEs or high glucose. BHC-containing serum could stabilize the stability of Müller cell membrane, inhibit the transcription of VEGF mRNA and decrease the protein expression of VEGF, which might be one of important mechanisms for preventing and treating diabetic retinopathy.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

[ ABSTRACT] AIM: To observe the effect of circadian rhythms on wound healing of mouse corneal epithelium. METHODS:The C57BL/6 male mice were used in the study.A part of corneal epithelium (2 mm in diameter) was struck off by a golf-like knife to form a round wound area.The dynamics of epithelial healing in the wound area were ob-served under microscope with fluorescein staining.In addition, with related antibodies and DAPI, the dynamic changes of the neutrophils, platelets and dividing cells were also investigated.RESULTS:The healing rates in LL group (12 h light/12 h light) and DD group (12 h dark/12 h dark) were obviously slower than that in LD group (12 h light/12 h dark), mainly showing delayed re-epithelialization, decreased epithelial cells, increased diameter of blood vessel, and delayed re-cruitment of neutrophils and platelets, but more cell number.CONCLUSION:Disruption of circadian rhythms significant-ly inhibits the wound healing of corneal epithelium, mainly through delaying the inflammation and re-epithelialization, but aggravating the inflammatory responses.
