OBJECTIVE: To investigate a nwe, simple technique for preparation of interferon-alpha-liposomes, which may be suitable for industrial use. METHODS The uniform design coupled with computerized optimization was utilized to screen the formulation and preparation procedure of interferon-alpha-liposomes. Pro-liposomes were prepared by the powder bed grinding method and combined with interferon-alpha-solution to form interferon-alpha-liposomes. Liposome size was determined by the particle size analyzer. Free interferon-alpha and interferon-alpha-liposome were separated by gel filtration. Then the recovered activity of interferon-alpha was analyzed by enzyme-linked immunosorbent assay. RESULTS The result demonstrated that the best interferon-alpha-liposome formulation was as follows: the protectant was sorbitol; weight ratio of protectant to lipid was 5:1; weight ratio of octadecytamin to lipid was 1:9; weight ratio of sobey phosphatidylcholine to cholesterol was 9:1 respectively. Interferon-alpha-liposome size determined by the particle size analyzer was 80.8+/-36 nm and the encapsulation efficiency was 59.0+/-3.3%. CONCLUSION The powder bed grinding method can be used to prepare pro-liposomes which can be easily combined with interferon-alpha-solution to form interferon-alpha-liposomes.

A collection of neurons in the upper lumbar spinal cord (lumbar segments 3 and 4) of male rats project to the lower lumbar spinal cord (lumbar segments 5 and 6) and release a gastrin-releasing peptide (GRP) to the somatic and autonomic regions, which are known to regulate male sexual reflexes. The GRP plays some special functions when bound to the specific GRP receptor (GRPR). The spinal GRP system is regulated by androgens. Accumulating evidence shows that GRP plays an important role in rat penile erection and ejaculation, and pharmacological stimulation of GRPRs with a specific agonist can restore penile reflexes and ejaculation in castrated male rats. Therefore, the GRP system appears to be a potential therapeutic target for the treatment of erectile dysfunction or ejaculatory dysfunction. The present paper briefly reviews the recent studies on the role of the spinal GRP system in regulating the sexual function of males.

Plant bioreactor called mocular farming has enormous potential to produce recombinant protein infinitely. Products expressed in plants has nature physico-chemical property and bioactivity. Plant bioreactor could be an safe, economic and convenient production system which has been widely applied in industries and agriculture, especially in the life science and pharmaceutical industry. The application of recombinant transgenic plant in the production of vaccines, antibodies and pharmaceutical proteins has become a hot point in the plant genetic engineering both at home and broad. However, there are some limiting factors of application such as yield, downstream processing and so on. The advantages and research progress for the mocular farming of pharmaceutical proteins recent three years was discussed, focusing on the existing problems and new strategies in this area.

Objective To investigate the proliferation and identification of dendritic cells(DC)de- rived from peripheral blood of patients with bladder cancer in vitro.Methods The mononuclear cells were prepared from peripheral blood of patients with bladder cancer by Ficoll-Hypaque centrifugation method,and were induced by the recombinant cytokines hGM-CSF(50 ng/ml),hlL-4(10 ng/ml)and hTNF-?(50 ng/ ml)for 2 weeks.The growth and morphology of DC were observed through the phase contrast or electron mi- croscope,and their pheuotypes were determined by flow cytometry.The capacity of DC to activate T cell-de- pendent anti-tumor immune responses was tested by MTT method.Results The DC cultured in vitro turned into suspensive growth from adhesive situation on the 6th day,then the number of DC increased con- tinuously and the cells showed the irregular morphologic appearance of DC with veiled edges on the 8th day. Flow cytometry showed that the mature DC expressed high levels of specific markers such as CD_(1a),CD_(83), CD_(86)and HLA-DR.T cells activated by DC showed strong cytotoxicity to bladder cancer cell line BIU87 with a killing rate of(48.8?3.7)%,while the killing rate of T cells which were not activated by DC was(25.7?1.5)%;the difference of the rate between them was significant(P＜0.01). Conclusions The DC can be cultured from peripheral blood of patients with bladder cancer by induction of rhGM-CSF,rhIL-4 and hT- NF-?in vitro.This may lay an experimental foundation for further research on DC vaccine.

OBJECTIVETo evaluate the efficacy and safety of three different spinal rotation manipulations for the treatment of lumbar disc herniation.

METHODSFrom September 2011 to April 2013,180 patients diagnosed as lumbar disc herniation were randomly divided into seat fixed rotation group (A), lateral position rotation group (B) and supine position rotation group (C) by using a digital table. Finally 10 patients were excluded and dropped, 170 patients were included in the study. There were 57 patients in group A, 57 patients in group B and 56 patients in group C. Baseline demographic characteristics of patients, clinical findings and indexes of health status had no statistically differences among three groups (P > 0.05). The manipulation was performed every other day, and the treatment duration for all patients was 3 weeks. Body pain (BP), Physical function (PF) in SF-36, Oswestry Disability Index (ODI) and adverse reactions were observed statistically 6 weeks, 3 months, 6 months, one year and two years after finishing treatment.

RESULTSBP, PF scores in 3 groups were significantly improved and ODI scores were significantly lower than those before treatment and the differences were statistically significant (P < 0.05); However, there was no significant difference among three groups in the BP, PF and ODI scores (P > 0.05). There were no obvious and serious adverse reactions among these groups.

CONCLUSIONBased on the theory of dislocation of bone joints in TCM, three kinds of spinal rotation manipulations can be used safely for the treatment of lumbar disc herniation, and the efficacy was similar.

OBJECTIVETo summarize the experience of intercostal video-mediastinoscopy (VMS) in treatment for mediastinal masses, malignant pleural effusion and palmar hyperhidrosis.

METHODSThe clinical data of 701 patients received intercostal VMS from November 2001 to June 2007 were summarized retrospectively. Forty-eight patients with mediastinal masses and 46 patients with suspected malignant pleural effusion underwent intercostal VMS pleural biopsy (39 cases with talc pleurodesis) and 607 patients with palmar hyperhidrosis underwent bilateral intercostals VMS thoracic sympathectomy.

RESULTSNo mortality and morbidity were reported in this group. Definitive pathologic diagnosis had been made through VMS mediastinal masses biopsy in mediastinal masses and pleural biopsy in pleura effusion. The efficiency of talc pleurodesis was 100% for 39 cases. The symptoms of sweating of hands in 607 patients with palmar hyperhidrosis disappeared completely, all patients' hands became dry with a 1.5 degrees C to 3.0 degrees C increase of the skin temperature immediately after operation. No recurrence occurred during the follow-up.

CONCLUSIONVMS is a simple, convenient and alternative procedure for the treatment of mediastinal masses, malignant pleural effusion and palmar hyperhidrosis.

To explore a new lyophilized preservation methods for human platelets, platelets were pre-treated with aldehyde, human albumin or trehalose was added to the system of condensed cooling as protectant to stabilize the structure of platelets. The optimal resuspending buffer was also selected in the study. The morphological changes of platelets were observed by using electron microscopy after lyophilization, and the expression of membrane proteins on platelets was detected also after lyophilization. The results indicated that the recovery rate of platelets treated with aldehyde was generally more than 60%. Aggregative ability was reduced a little than the platelet untreated. 5% of human albumin had an advantage over 40 mmol/L of trehalose in respect of the preservation effect. In the way of keeping aggregative ability, PPP was obviously better than PBS. The results of electron microscopy displayed that organelles including mitochondria and excreted granules could be observed distinctly. Whereas, expression of membrane proteins of platelet treated with aldehyde was evidently dropped as compared with those of the fresh platelet. In conclusion, aldehyde as a novel protective agent, has excellent effects on lyophilization of platelets and is worthy to be further studied.
