Objective To prepare sustained-release danshensu microcapsules by spray drying.Methods Encapsulation efficiency of different coating materials was compared.The spray process was optimized using a central composite design for two variables to obtain microcapsules with microcapsules yield.Furthermore, in vitro release of danshensu microcapsules was determined.Results PVA was chosen as coating material and the ratio of coating material to core material was 3:1.The inlet air temperature was 190℃,the feed flow rate was 36 r/min,encapsulation efficiency was 85.0%,and microcapsules yield was 56.1%.The particle size of more than 70%microcapsules was between 6—12?m.Conclusion The optimized conditions of spray drying are reasonable,danshensu microcapsules can be used as sustained-release preparation.

In order to study the effect of seed soaking with different aluminum solution on seed germination and seedling physiological characteristics of Platycondon grandiflorum, two P. grandiflorum varieties'seed (the white flower and the purple flower) were soaked in Al3+ solution with different concentrations (0, 10, 100, 250, 500, 750 and 1000 mg x L) for 24 h, then germinated in illumination incubator. Results showed that the aluminum toxicity on the trends of the germination rate, germination index and vigor index was positive associated with its concentration, and the Al tolerance of the purple was slightly greater than that of the white. There were some relationships between the physiological indices, which were the leakage rate of electrolyte, the malonaldehyde (MDA) content, the activities of peroxidase (POD) and superoxide dismutase (SOD) , the free praline(Pro) and the soluble sugar contents, with the concentrations of Al. It was suggested that there was Al tolerance difference between the two P. grandiflorum varieties: the purple flower was greater than the white.

Objective To study the effect different concentrations of HDAC6 inhibitor tubacin on the proliferation,morphology and membrane surface ultrastructure of bone marrow mesenchymal stem cells(BMSCs).Methods Primary BMSCs were cultured.The P4 generation cells were taken for conducting the experiment.The different concentrations of tubacin were used to treat the cells fro 24 h.The cells survival rate was detected by MTT assay.The atomic force microscopy(AFM) was applied to observe the cellular morphology and surface ultramicrostructure and detect the mechanical property in different groups.Results The MTT results showed that low concentration of tubacin had the effect for promoting BMSC proliferation;the AFM results showed that compared with the control group,the height and width of BMSCs after treating by low concentration of tubacin,the membrane surface roughness was decreased and cellular hardness was increased.Conclusion Low concentration of tubacin can promote the BMSC proliferation,causes the changes of morphology and membrane surface ultramicrostructure,enhances the mechanical property and increases the cell implantation treatment efficiency.

OBJECTIVETo summarize the general condition, regional distribution, prevalence and clinical characteristics of Shandong province based on hemophilia case registry information.

METHODSA retrospective study was carried out on 1979 hemophilia patients registered at Shandong Hemophilia Registration Center.

RESULTSThe 1979 cases have included 1704 hemophilia A and 275 hemophilia B patients. Hemophilia A was characterized as severe in 1021 patients (59.9%), moderate in 483 patients (28.4%), and mild in 200 patients (11.7%); while hemophilia B was characterized as severe in 125 patients (45.4%), moderate in 116 patients (42.2%), and mild in 34 patients (12.4%). The median age was 23 years (ranging from 1 month to 81 years), and most were young patients. Joint deformity occurred in 963 patients, and 948 patients had a family history of hemophilia. All counties of Shandong province had patients except for Changdao county and Fushan district of Yantai city. The prevalence of Heze city and Dongying city (3.39/100 000 and 3.05/100 000, respectively) were relatively higher.

CONCLUSIONThe above data revealed epidemiological and clinical characteristics of Shandong Province. Patient-centered registry system allowed a more detailed and accurate patient information, and promoted the comprehensive care of hemophilia, which also suggested the necessity for the establishment and improvement of the National Hemophilia Registry System.

The improvement of hemophilia treatment is attributed to the development of transfusion medicine, and the discovery of cryoprecipitate has opened up a new era of hemophilia treatment, laying the foundation for the development of modern hemophilia therapies. But with the further improvement of hemophilia treatment and the emergence of new treatment methods, transfusion medicine no longer plays a dominant role in hemophilia treatment. The new technologies and methods for hemophilia treatment can provide reference for the development of transfusion medicine, thereby better serving clinical practice and patients.

Hemophilia is a hereditary bleeding disorder where the only effective treatment is factor replacement therapy. The main contradiction of hemophilia in China is the contradiction between the increasing demand for quality of life of hemophilia patients and insufficient medical insurance, medical treatment and medicine. Expensive treatment costs are the main reason for patients to "be impoverished due to illness" and "return to poverty due to illness". This article analyzes the current status of the hemophilia aid system through the existing literature data and existing patient aid projects. Cooperation of social insurance, social relief and high-quality medical services is critical to a complete hemophilia comprehensive medical aid system, so that hemophilia patients can receive standardized diagnosis and treatment, and try to achieve the close quality of life as normal.

OBJECTIVETo investigate the mechanism of N- Arachidonoylethanolamine (ANA) on inhibiting platelets (PLT) apoptosis under standard blood bank storage conditions.

METHODSSamples taken from collected apheresis PLT by the Amicus instrument were split into three parts. An aliquot of 0.5 μmol/L ANA were added to one part of storage PLT as the ANA group; an aliquot of 0.5 μmol/L ANA and 1 μmol/L SR141716 was added to the another part as the ANA + SR141716 group; and the third part without ANA and SR141716 as the control group. These samples were stored on a flat-bed shaker at (22 ± 2) ⁰C for 7 days. The expression of phosphatidyl serine (PS) positive, phospho (p)-Akt, Akt, p-Bad, Bad, caspase-3, caspase-9, cytochrome C (Cyt-C) and BCL-XL interaction with Bak were detected.

RESULTSThe rate of PLT PS positive in ANA group decreased significantly than that in control group[ (8.29 ± 1.44) % vs (14.24 ± 2.47) %, P<0.05]. The release of Cyt-C from mitochondria to cytosol in ANA group decreased significantly compared with control group[ (3.29 ± 1.44) % vs (15.24 ± 3.40) %, P<0.05]. Also the expressions of p-Akt and p-Bad in ANA group increased significantly than those in control group[ (71.33 ± 10.26) % vs (35.00 ± 6.00) %, P<0.05; (39.00 ± 9.64) % vs (10.33 ± 1.53) %, P<0.05, respectively]. Higher amounts of Bak protein were co-precipitated with BCL-XL in ANA group than that in control group (about 2.6 fold, P<0.05). The expressions of cleaved caspase- 9 and caspase- 3 in ANA group decreased significantly than those in control group[ (9.63 ± 1.47) % vs (23.24 ± 2.47) %, P<0.05; (6.30 ± 1.40) % vs (13.20 ± 2.50) %, P<0.05, respectively]. There were no significantly changes between ANA+SR141716 and control groups (P>0.05).

CONCLUSIONANA protected PLTs from apoptosis as a result of inhibiting the release of Cyt-C from mitochondria to cytosol by modifying the expressions of apoptosis-relative proteins.

Professor 's experience of acupuncture combined with medication for epilepsy is summarized, which is explained from epilepsy's etiology and pathogenesis, diagnosis and treatment of acupuncture and medication, respectively. Besides, the theoretical foundation and use instruction of acupuncture technique "-" for epilepsy are introduced. Professor highly values the adherence to etiology and pathogenesis, pays attention to syndrome differentiation and searches for the primary disease cause. He proposes the wind, phlegm, stasis and deficiency are the pathogenesis of epilepsy, and points out acupuncture could be applied during attack stage and remittent stage, but electroacupuncture should be used with caution. Regulating spirit is the key for treating epilepsy. The combination of acupuncture and medication could regulate the governor vessel and guide to the origin, which have significant curative effect.
