Objective To investigate the clinical efficacy of auricular plaster therapy plus scalp acupuncture in treating post-stroke depression.Methods One hundred and twenty-five patients with post-stroke depression were randomly allocated to group A of 42 cases, group B of 42 cases and group C of 41 cases. Group A received scalp acupuncture alone; group B, auricular plaster therapy alone; group C, auricular plaster therapy plus scalp acupuncture. The Hamilton Depression Scale (HAMD) score was recorded in the three groups before and after treatment. The clinical therapeutic effects were compared between the three groups. Results There was a statistically significant pre-/post-treatment difference in the HAMD score in the three groups after two months of treatment (P<0.01). There was a statistically significant difference in the HAMD score between group C and group A or B after one and two months of treatment (P<0.05). The total effective rate and marked efficacy rate were respectively 95.0% and 33.3% in group A, versus 88.1% and 35.7% in group B, and 92.7% and 56.1% in group C, and the marked efficacy rate in group C were significantly different from that in group A and group B (P<0.05). There is not a statistically significant difference in the total effective rate among the three groups (P>0.05).Conclusion Auricular plaster therapy plus scalp acupuncture is an effective way to treat post-stroke depression.

Objective:To establish an in vitro root canal model infected by Enterococcus faecalis and to observe the morphology, distribution and relative position of Enterococcus faecalis in infected root canals.Methods: Ten human healthy premolars extracted for orthodontic reasons were collected. Following sterilization , a total of 5 specimens were aseptically transferred to separate Eppendorf tubes containing 1. 5 mL brain-heart infusion broth (BHI) inoculated with 0.1 mL Enterococcus faecalis suspension that had been adjusted to Mcfarland 5, and were incubated at 37℃ for 21 days. The other 5 specimens were as controls. The roots of all specimens were then split into two halves along the mesiodistal axis. One half was processed with light microscopic ( Brown & Brenn stain) to check the bacteria in dentinal tubules, and the other was observed with SEM to investigate the bacterial status in infected root canals. Results: Enterococcus faecalis could penetrate into the dentinal tubules about 330-1 000μm. A dense bacterial aggregation composed of Enterococcus faecalis and amorphous matrix was observed in the apical third of the root canals, whereas Enterococcus faecalis were seen free-floating or planktonic in the crown and middle third of the root canals . No microorganisms were found in the root canals of the controls. Conclusion:Enterococcus faecalis could form bacterial biofilm on the root canal walls and penetrate into the dentinal tubules. The in vitro model designed was simple, and had good practicability to make a further comparative evaluation of various antimicrobial methods in the reduction of intracanal bacteria.

Objective:To evaluate the cytotoxicity of sodium hypochlorite(NaOCl) and chloramine-T at a same available chlorine concentration. Methods: L929 fibroblasts were used to test the cytotoxicity of NaOCl and chloramine-T at a same available chlorine concentration (0.500 0%, 0.250 0%,0.200 0%, 0.150 0%, 0.125 0%, 0.062 5%). Cell viability after 2 h, 30 min or 10 min exposure were measured by MTT assay. Results: Except the 0.500 0%-2 h group and 0.062 5%-30 min group, cell viability of NaOCl groups were higher than chloramine-T group(P<0.05). Conclusion: NaOCl solution has less cytotoxicity than chloramine-T at a same available chlorine concentration lower than 0.250 0%.

Objective To survey the incidence of adverse reaction induced by traditional Chinese medicine injection and provide valuable suggestion for using traditional Chinese medicine injection.Methods Clinical data of 1860 patients who were under treatment of traditional Chinese medicine injection during January 2010 to December 2014 were studied to survey adverse reaction incidence, effected system-organs and risk factors of adverse reaction.Results Comparison of incidence adverse reaction of traditional Chinese medicine injection, Qingkailing injection adverse occurrence rate reached the highest 11.76% for all types, followed by Shenmai injection and Shuanghuanglian injection.Adverse reactions involving the organ and the performance was compared, adverse reactions mainly involved the organs for the skin and accessories, circulatory system, accounting for 56.15%, the incidence of adverse reactions of the rest of the organ system was less.Not determine the treatment based on differentiation of symptoms and signs, combined with injection, ultra treatment application and distribution of liquid static for a long time all differences were statistically significant ( P <0.05), leading to the main risk factors of the occurrence of adverse reactions.Conclusion Traditional Chinese medicine injections occurred and the incidence of adverse reactions was higher, wider range, organ involvement mainly skin and its appendages and circulatory system, not dialectical treatment and rational drug use is lead to adverse risk factors, actively preventment and timely treatment to reduce the incidence of adverse reactions.
