Observation on the Efficacy of Acupuncture plus Intradermal Needle in Treating Mild-to-moderate Post-stroke Depression / 上海针灸杂志

Objective To observe the clinical efficacy of acupuncture plus intradermal needle in treating mild-to-moderate post-stroke depression (PSD). Method Ninty patients with mild-to-moderate PSD were randomized into group A, B and C, with 30 cases in each group. All the groups were intervened by selecting Baihui (GV20), Shenting (GV24) and Yintang (GV29). Group A received acupuncture plus intradermal needle; group B, intradermal needle alone; group C, acupuncture plus sham acupuncture. Hamilton depression rating scale (HDRS) score and Barthel index (BI) score in the three groups were observed before and at the end of the treatment, and the clinical efficacies of the three groups were compared. Result The HDRS score and BI score showed a significant change after the treatment in the three groups (P<0.01). After the treatment, the HDRS score and BI score in the group A and group B was significantly different from those in group C (P<0.05). The total effective rate was 90.0％ in group A versus 86.7％in group B, and 73.3％ in group C; there was a statistically significant difference between group C and group A or B (P<0.01, P<0.05). Conclusion Both acupuncture plus intradermal needle and intradermal needle alone are effective approaches in treating mild-to-moderate PSD. The treatment efficacy of these two methods is similar.

Biofiltration of ethyl acetate and amyl acetate using a composite bead biofilter.

Biodegradation kinetic behaviors of ethyl acetate and amyl acetate in a composite bead biofilter were investigated. The composite bead was the spherical PVA/peat/KNO3/GAC composite bead which was prepared in our previous works. Both microbial growth rate and biochemical reaction rate were inhibited at higher inlet concentration. For the microbial growth process, the microbial growth rate of ethyl acetate was greater than that of amyl acetate in the inlet concentration range of 100-400ppm. The degree of inhibitive effect was almost the same for ethyl acetate and amyl acetate in this concentration range. The half-saturation constant Ks values of ethyl acetate and amyl acetate were 16.26 and 12.65ppm, respectively. The maximum reaction rate Vm values of ethyl acetate and amyl acetate were 4.08 and 3.53gCh(-1)kg(-1) packed material, respectively. Zero-order kinetic with the diffusion limitation could be regarded as the most adequate biochemical reaction model. For the biochemical reaction process, the biochemical reaction rate of ethyl acetate was greater than that of amyl acetate in the inlet concentration range of 100-400ppm. The inhibitive effect for ethyl acetate was more pronounced than that for AA in this concentration range. The maximum elimination capacity of ethyl acetate and amyl acetate were 82.3 and 37.93gCh(-1)m(-3) bed volume, respectively. Ethyl acetate degraded by microbial was easier than amyl acetate did.
