Objective To observe the clinical effect and the incidence of neuralgia of acupoint injection with nerve growth factor onRamsay Hunt syndrome. Methods 65 patients with Ramsay Hunt syndrome were divided into treatment group (n=33) and control group(n=32). All the patients were treated with the anti-virus and glucocorticoid medicine, and were acupunctured at the similar points with electroacupuncturewith the disperse dense wave. The treatment group was injected with mouse nerve growth factor at the acupoints. 2 days offevery 5 times, 10 times as a course for 2 courses. The treatment effect and the incidence of sequelae neuralgia after 3 months were compared.Results The total effective rate of treatment group (93.9%) was significantly higher than control group (71.9%) (P<0.01). The incidenceof sequelae neuralgia of the treatment group (6.3%) was significantly lower than the control group (26.7%) (P<0.01). ConclusionAcupoint injection of mouse nerve growth factor can improve the efficacy and reduce the incidence rate of sequelae neuralgia in patientswith Ramsay Hunt syndrome.

Objective To study the application of waveforms in treatment of peripheral facial paralysis with electroacupuncture. Methods 66 patients with peripheral facial paralysis were divided into two groups: treatment group (34 cases) and control group(32 cases). All the patients were acupunctured at the similar points with electroacupuncture, while the disperse-dense wave and the discontinuous wave were used successively in the treatment group, and the disperse-dense wave was used alone in the control group. Results There were significant differences between the two groups in the total effective rate and the days for cure (P<0.01). Conclusion The effect of alternate disperse-dense wave and discontinuous wave is superior to that of disperse-dense wave alone in electroacupuncture treatment for peripheral facial paralysis.

Myoblast transplantation has been carried out for a certain period,but its efficiency in repairing inherited myopathy or severe muscular injury is not satisfactory.The improvements in myoblast culture,transplantation approach,recipient and cell preparation before transplantation,scaffold material and its selection,and body immunity can positively influence transplantation efficacy,and improve recipient function.In addition,these improvements influence the prospect of myoblast transplantation or cell-mediated gene therapy.

Objective To explore the size changes of erythrocytes infected with Plasmodium malariae,so as to improve the basic?level experimenters’microscopy capabilities for P. malariae identification in thin blood smears. Methods The micro?scopic features of erythrocytes infected with P. malariae in thin peripheral blood smears were observed,and a microscope image processing software was used to measure and analyze the diameter changes of the erythrocytes infected with P. malariae. Re?sults The diameter of erythrocytes infected with P. malariae decreased significantly compared with that of the normal erythro?cytes. The three parameters in this study:the diameter of erythrocytes,the value of diameter variation,and the ratio of diameter variation varied at different developmental stages of P. malariae,and the differences were statistically significant(all P<0.01). The variances of the three parameters grouped by different cases or different developmental stages in different cases were ana?lyzed,all showing statistically significant differences(all P<0.01). Conclusion All the developmental stages of P. malariae will cause the decrease of the diameters of infected erythrocytes in peripheral blood smears,but the influence on the diameter of erythrocytes,value of diameter variation,and ratio of diameter variation varies at different developmental stages in different cases.

Polyamidoamine (PAMAM) dendrimers is considered a better genetic carrier for its ability to form with DNA a nano-sized polyelectrolyte complex of high stability and dissolubility. The mechanism of PAMAMmediated gene endocytosis has been fairly clear and the researches in vitro have confirmed that PAMAM had high transfection efficiency and low cytotoxicity. The researches in vivo have further confirmed that PAMAM had a potential application foreground in the field of gene therapy including in the prevention and treatment of ewing's sarcoma and pulmonary fibrosis, in heart transplantation, and in the preparation of falciparum malaria vaccine.

OBJECTIVE:To explore the treatment effect and complication prevention of various stent materials for intracranial arteriostenosis.METHODS:A computer-based online search of Science Direct and Ei database (1998-01/2009-10) was performed for English articles with the key words of "intracranial arteriostenosis,stent placement" In addition,CNKI and CBM database (1998-01/2009-10) were searched for related Chinese articles with the same key words in Chinese.Moreover,related works were manually searched.Studies regarding various stent materials for intracranial arteriostenosis were included,including basic and clinical experiments.RESULTS:Multicenter studies of worldwide show that stent implantation displays obvious advantages in treating carotid artery stenosis compared with carotid endarterectomy.Recently,with developing of balloon and stent compliance,as well as stent technology,and application of various novel materials and cerebral protection device,stent has become a safe and effective therapy for intracranial arteriostenosis.However,complications following stent implantation,such as restenosis,ischemic stroke,cerebral hemorrhage hypertransfusion syndrome,and cerebral angiospasm,limit its application.CONCLUSION:The safety and efficacy of intracranial stent implantation remains validation of multicenter and perspective studies.High incidence of restenosis following stent implantation requires further improvement.
