The research on clinical efficacy evaluation of traditional Chinese medicine (TCM) is a hot and difficult issue in the field of TCM. However, the overall level of current related research also needs to be improved. There are still a lot of academic controversies in the field of TCM clinical efficacy evaluation. The author believed that before conducting research, it is necessary to sort out core issues of TCM clinical efficacy evaluation, which in-clude the concept of TCM clinical efficacy and its evaluation. In recent years, Chinese scholars have conducted a series of studies on these issues and have some achievements. To think and answer these questions will play an important role for the ultimate resolution of problem of TCM clinical efficacy evaluation.

Objective:
To describe the epidemiological characteristics of suicide death and self-harm/suicide in China from 2006 to 2016.
Methods:
Data in this study are from the datasets of National Death Cause Surveillance from 2006 to 2016 and the National Injury Surveillance Dataset 2016. The age-standardized death rate based on the population census in 2000 was used to describe the trend of suicide over years. This study also described the epidemiological characteristics of suicide death and the demographic characteristics, suicide methods and severity of patients who sought medical help after committing suicide or self-inflicted injury in 2016.
Results:
Age-standardized suicide mortality had been declining from 9.23/100 000 in 2006 to 5.33/100 000 in 2016 by 42.25%. Suicide mortality increased with age. In 2016, the suicide mortality in China was 7.05/100 000, and among people over 85 years old was 49.49/100 000. In 2016, the dominant two suicide methods were poisoning (39.12%) and sharp injury (25.62%). The first leading method of suicide in rural population, urban population and young people aged 10-to 17-year-old was poisoning (65.13%), sharp injury (29.90%) and fall (25.47%), respectively. As age increased, the severity of suicide/self-inflicted injury increased. The proportions of serious cases among young people aged 10-to 17-year-old and older people aged 60 years old and above who sought medical help after committing suicide or self-inflicted injury were 4.88% and 26.86%, respectively.
Conclusion
China′s suicide mortality has been declining and special attention should be given to the suicide of old people.

Objective:
To analyze the characteristics distribution of falls among students aged 6-17 in 2018, and to provide data support for preventing falls among students and formulating the corresponding policies.
Methods:
Data of falls among students aged 6-17 in China in 2018 were collected from the the National Injury Surveillance System (NISS) for analyzing its demographic characteristics, injury occurrence and clinical traits of falling.
Results:
In total, 42 735 cases of fall aged 6-17 were collected from the NISS in China in 2018, which accounted for 54.03% of all cases, with a sex ratio of 2.34∶1, the proportion of students aged 6-11 was the highest(53.78%). The proportion of falls from March to June was the highest(42.12%), and the peak time when falls occurred was forenoon 10:00-10:59(8.40%). School and school-related area(40.40%), home(18.96%) and public residential institution (15.35%) were the sites where falls mainly occurred. The top three activities when falls occurred were leisure activities(47.41%), sports activities(23.90%) and walking(9.77%). Bruise/scrape(54.49%), sprain/strain(21.98%) and fracture(12.69%) were the major nature of injury. The most common body parts falls involved were lower limbs(34.71%), head(29.85%) and upper limbs(25.10%). The injury of falling was mainly characterized by mild ones(83.44%).
Conclusion
There were more cases of falls on students aged 6-17 from the NISS in China in 2018, mainly males. The epidemiological characteristics were relatively variable, so targeted prevention program of falls should be conducted.
