With the construction of a pluralistic value system， the concept of patient autonomy has gradually been established. The paternalistic medical decision-making model has been widely questioned and criticized， gradually losing its dominant position. Due to the differences in positions and values， there are conceptual differences and decision-making conflicts between doctors and patients， and the doctor-patient game runs throughout the entire medical decision-making process. However， after analyzing the advantages and disadvantages of both the paternalistic medical decision-making model and the patient autonomous decision-making model， it can be found that blindly devaluing any medical decision-making model is not the optimal solution to maximize patients’ rights and interests. The medical side needs to fully respect patient autonomy， while the patient side should also clarify the concept of equal rights and responsibilities. Through the optimization of the policies and systems， both doctors and patients can cultivate independent decision-making personalities and rational thinking abilities， ultimately achieving doctor-patient consensus through equal dialogue and communication.

Fertilization is a crucial step for origin of life.During Assisted Reproductive Technologies (ART),total fertilization failure is complex and unpredictable.Total fertilization failure may related to some abnormal cellular mechanistic events,such as:any stage of sperm and cumulus-oocyte-complexes penetration,sperm-zona pellucida binding / penetration,sperm-oocyte membrane binding,oocyte activation,sperm discondensation or pronuclear formation.Most of total fertilization failure could be solved by intracytoplasmic sperm injection.But oocytes of some patient still can't fertilize successfully,even though assisted oocyte activation be used.As for total fertilization failure patients in ART,combining the mature of oocyte,sperm quality and some trail to improve clinical protocol in later cycle may prevent failure to happen again.

Objective: To seek the optimal acupuncture time for primary dysmenorrhea and provide clinical basis for optimal acupuncture treatment protocol. Methods:A total of 90 eligible cases were randomly allocated into three groups, 30 cases in each group. Points Guanyuan (CV 4), bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for patients in all three groups, with a different treatment duration: 15 min in group A, 30 min in group B and 45 min in group C. Then the clinical efficacy in each group was evaluated by pain symptom scoring. Results:As for the pain symptom scores, there were statistically significant intra-group differences between before and after treatment in three groups (allP<0.05); coupled with statistically significant inter-group differences between group B and the other two groups (bothP<0.05). As for clinical efficacy, there were statistical differences between group B and the other two groups (bothP<0.05), indicating that 30 min of acupuncture is the optimal duration in the treatment of dysmenorrhea. Conclusion:With the same needling manipulation, 30 min of acupuncture treatment achieves a better efficacy for primary dysmenorrhea.
