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.

Objective:To investigate procalcitonin and C-reactive protein levels in diarrheal patients who underwent irinotecan che-motherapy. Methods:Procalcitonin and C-reactive protein were detected among 85 diarrheal and 63 non-diarrheal patients after irinote-can chemotherapy. Results:According to WHO classification, patients without diarrhea are classified as grade 0, whereas patients with diarrhea can be classified as gradesⅠ-Ⅳ. In grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣpatients, the levels of procalcitonin were 0.29 ± 0.17, 0.30 ± 0.18, 0.36 ± 0.20, 1.24 ± 0.22, and 2.15 ± 0.26 ng/mL on the second day, respectively. However, on the fourth day, the procalcitonin lev-els were 0.28 ± 0.15, 0.30 ± 0.14, 0.34 ± 0.18, 2.00 ± 0.22, and 2.40 ± 0.28 ng/mL, respectively. Moreover, in grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣ, the levels of C-reactive protein were 6.06 ± 1.85, 6.12 ± 1.16, 6.20 ± 1.68, 22.62 ± 4.55, and 31.26 ± 5.23 mg/L on the second day, respectively. On the fourth day, the C-reactive protein levels were 5.80 ± 1.82, 5.94 ± 1.14, 6.15 ± 1.55, 30.52 ± 4.74, and 38.67 ± 5.68 mg/L, respectively. No significant difference was found between the procalcitonin and C-reactive protein levels of stagesⅠandⅡpa-tients (P>0.05), but a significant difference was found between stagesⅠ, andⅡpatients and stagesⅢandⅣpatients (P<0.05). Con-clusion: Monitoring levels of procalcitonin and C-reactive protein may be helpful in the early evaluation of the severity of diarrhea. This process has prognostic effect and can be used to assess whether patients have enterogenous bacterial infection. Monitoring the lev-els of these proteins has certain clinical value and can be used to guide early anti-infection therapy.

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.

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 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.
