RESUMO
Objective To observe the effect of acupoint thread-embedding at Neiguan (PC6) and Zusanli (ST36) on anxiety and sleep disorders after heroin withdrawal. Method Sixty-seven patients with heroin addiction were randomized into a Neiguan group (25 cases), a Zusanli group (22 cases) and a Neiguan plus Zusanli group (20 cases), to receive corresponding treatments once every 20 d, for 4 sessions in total. The Self-rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) were adopted to observe the anxiety and sleep condition before and after the treatment. Result After 60 d thread-embedding treatment, the total and standard SAS scores, sleep initiation time and total PSQI score were significantly decreased in the 3 groups (P Neiguan group >Zusanli group (P0.05). Conclusion It's effective to use thread-embedding at Neiguan and Zusanli independently or together for anxiety and sleep disorders after heroin withdrawal, but the efficacy is more significant when the two points are used in combination, indicating the synergy of acupoints.
RESUMO
Objective To study the clinical efficacy of both acupuncture combined with flames and simple acupuncture and moxibustion treatment of nerve root cervical spondylosis,so as to provide appropriate basis for the improvement of nerve root cervical spondylosis treatment. Methods A total of 60 cases of nerve root cervical spondylosis were enrolled for the study and randomly divided into two groups with the treatment of acupuncture combined with dragon moxibustion group(treatment group,n=30)and simple acupuncture group(control group,n=30). The clinical symptoms before and after treatment,and signs changes between the two groups were compared. Results Patients of both two groups showed significant im?provement after treatments(P<0.05);CSR simplify McGill Pain Scale scores inquiry(P<0.05). The total effective rate of the treatment group was 96.67%,which was 90.0%in the control group,with statistically significant difference(P<0.05). It indicated that the combined use of acupuncture and moxibustion therapy had better efficacy than simple acupuncture treatment. Conclusion The combined use of acupuncture and moxibustion therapy with flames in nerve root cervical spondylosis showed better clinical effect,which can be used as a preferred method of clinical treatment pro?grams.
RESUMO
Objective To establish cell strain expressing the genes of HIV vpr and mutant HIV vpr-FS, and to explore cell apoptosis ability by HIV Vpr and Vpr-FS. Methods The recombinant plasmids were constructed by cloning HIV vpr and HIV vpr-FS genes into the eukaryotic expression vector pcDNA3.1respectively. To determine the primary structures of HIV vpr and HIV vpr-FS, plasmids were cleaved by restriction enzymes. After the plasmids were transfected into HeLa cells by liposome, the HeLa cells were selected with G418 selective medium, mRNA expression of HIV vpr or HIV vpr-FS of transfected cells was detected by RT-PCR, and Vpr and Vpr-FS protein expression were detected by Western blot assay respectively. The DNA content and the percentage of apoptosis in HeLa HIV vpr cell, HeLa HIV vpr-FS cell and HeLa pcDNA3.1 cell were monitored by flow cytometry and the DNA fragmentation was analyzed by agarose gel electrophoresis. Results BamH Ⅰ and Hind Ⅲ cleavaged products of pcDNA3.1-vpr and pcDNA3.1-vpr-Fincluded 342 bp length fragments suggesting that the length of DNA sequence containing HIV vpr (HIV vpr-FS) within pcDNA3.1 was the same as theoretical length. The HeLa cells transfected by pcDNA3.1-vpr or pcDNA3, l-vpr-FS and selected with G418 could express HIV vpr or HIV vpr-FS by RT-PCR, and express HIV Vpr or HIV Vpr-FS protein by Western blot. The results of flow cytometry and DNA fragmentation showed that there was significant different in the number of apoptotic cells between HeLa HIV vpr cell and HeLa HIV vpr-FS cell, but the difference between HeLa HIV vpr-FS cell and control group was not obvious. Conclusion Recombinant plasmids pcDNA3.1-vpr and pcDNA3. 1-vpr-FS were constructed successfully, and the cell strain expressing HIV Vpr and HIV Vpr-FS proteins was established. The HIV Vpr could induce host cell apoptosis, while the mutant of Vpr did not or weakened this ability. This study provides foundation for further study on HIV vpr gene.
