The use of human biological specimen has great significance to the development of biomedicine. Meanwhile, the powerful electronic data set with sophisticated analytic techniques creates challenge to the protec-tion of private information. As for the research with human biological specimen, how to facilitate the research con-duct on the basis of ethical principles is one of the key considerations when the US Department of Health and Hu-man Service initiated the revision of Code of Federal Regulations ( CFR) -theCommon Rule for subject protec-tion. The Notice of Proposed Rulemaking ( NPRM) proposed:Respect for autonomy will be enforced by broad con-sent to enforce and waiver of consent intend to be rare;If the research risks only involve privacy protection, review process will be simplified under the premise of ensuring the implementation of privacy laws and other protective measures. The paper introduced the revisions related to the researches using human biological specimen in NPRM, analyzed the terms of broad consent, exemption and exclusion, and explored the elicitation to ethical review prac-tice in China.

Objective To observe the clinical effect of Yangyin Tongluo Pills combined with acupuncture for the treatment of cerebral infarction sequela. Methods One hundred patients with cerebral infarction sequela were evenly randomized into treatment group and control group. The control group was given acupuncture therapy combined with oral use of clopidogrel, and the treatment group was given acupuncture therapy combined with oral use of Yangyin Tongluo Pills (mainly composed of Fructus Lycii, Flos Chrysanthemi, Radix Rehmanniae, Cortex Moutan, Radix Salviae Miltiorrhizae, Flos Carthami, Semen Persicae, Pheretima, Rhizoma Gastrodiae, Ramulus Uncariae cum Uncis, Spica Prunellae, Radix Glehniae, Radix Ophiopogonis, Fructus Schisandrae Chinensis, Radix Pseudostellariae) . One month constituted a treatment course, and the treatment covered 2 courses. After treatment, the therapeutic effect of the two groups was evaluated, and the changes of National Institute of Health Stroke Scale ( NIHSS) scores and Barthel Index Scale for activities of daily living ( ADL) , and hemorrheology indexes were observed before and after treatment. Results (1) After treatment for 2 courses, NIHSS scores were decreased, ADL scores were increased in the two groups (P<0.01 compared with those before treatment) , and the improvement of the treatment group was superior to that of the control group ( P<0.01) . ( 2) After treatment, hemorrheology indexes were much improved in the treatment group ( P<0 . 05 or P<0 . 01 ) , but remained unchanged in the control group ( P>0.05) . The treatment group had better effect on improving hemorrheology indexes than the control group (P<0.05) . (3) The total effective rate of the treatment group was 90.00% and that of the control group was 64.00%, the overall therapeutic effect of the treatment group being superior to that of the control group (P<0.05) . Conclusion Yangyin Tongluo Pills combined with acupuncture are effective for the treatment of cerebral infarction sequela, and the effect is superior to that of acupuncture combined with clopidogrel.
