On the basis of literatures and standards relating to Tibetan medicine, the varieties, origin, standards and efficacy of Saxifragaceae plant used in Tibetan medicine were summarized. According to the findings, 75 species(including varieties) in 8 genera of Saxifragaceae plants, involving 21 varieties, are used in Tibetan medicine. Among them, 9 commonly used varieties, namely Songdi, Sedi, Yajima, Aoledansaierbao, Jiansidawu, Saiguo, Katuer, Sangdi, Maoqinghong, are recorded in Chinese Pharmacopoeia, Ministry Standards for Tibetan Medicine, Tibetan Medicine Standards and other local standards, accounting for 42.9% of the total number of varieties. Tibetan names, Tibetan translation of Chinese names, as well as original plant of Tibetan medicine varieties are quite different in relevant Tibetan medicine standards and literatures, which resulted in common phenomena of synonym and homonym. The standards of most varieties only involve characters, and microscopic, physical and chemical identification, with low quality standards. Based on the results of the analysis, this paper suggests strengthening surveys on herbal textual research, resources and current utilization of Saxifragaceae plants used in Tibetan medicine, summarizing the varieties, establishing improved quality standards, and perfor-ming a comparative study on therapeutic material basis and biological activity of different original plants, in order to promote rational use of these medicinal plant resources, and ensuring the accuracy, safety, and effectiveness of clinical medication.

2.Standard operating procedure for microscopic tooth preparation.
Chinese Journal of Stomatology 2021;56(4):318-323
Tooth preparation is the primary and core operation technique for prosthodontics. Microscopic tooth preparation can improve the accuracy and efficiency of the operation. Experts from Society of Prosthodontics, Chinese Stomatological Association formulated the standard operating procedure for microscopic tooth preparation, so as to standardize its design points and operating procedures, highlight the difference between this novel technique and the traditional naked eye tooth preparation and promote the application of microscopic tooth preparation.

OBJECTIVE:
To explore the clinical characteristics and genetic basis for a pair of twins affected with hyaline fibromatosis syndrome (HFS).
METHODS:
Clinical data of the twins were retrospectively analyzed. High-throughput sequencing was carried out to detect potential pathogenic variants. CLUSTALX was employed to analyze cross-species conservation of the mutant amino acids. Impact of the mutations was predicted by using software including PolyPhen-2 and Mutation taster.
RESULTS:
The pair of twins have featured growth and intelligence retardation, and were found to carry compound heterozygous variants of the ANTXR2 gene including c.1214G>A and c.1074delT, among which c.1214G>A was unreported previously. Both variants were predicted to be pathogenic. In addition to growth and mental delay, the pair of twins also featured hyperplasia of the gum and soft tissue-like masses of the auricle. The younger brother had rupture of the auricle mass during follow-up.
CONCLUSION
The patients' condition can probably be attributed to the compound heterozygous variants of the ANTXR2 gene. Above finding has facilitated molecular diagnosis of the patients.

Chinese Journal of Medical Genetics 2021;38(5):503-505
OBJECTIVE:
To investigate the genetic polymorphisms of 21 non-combined DNA index system short tandem repeat (STR) loci in Hainan Li population.
METHODS:
DNA samples from 339 unrelated healthy individuals of Li population from Hainan Province were extracted and amplified with fluorescence labeled multiplex PCR system. PCR products were electrophoresed on an ABI3130 Genetic Analyzer following the manufacturer's instructions. Allele designation was performed with a GeneMapper ID-X by comparison with the allele ladder provided by the corresponding kit.
RESULTS:
A total of 173 alleles and 489 genotypes were observed for the 21 STR loci, respectively. The frequencies of alleles and genotypes were 0.0010-0.5434 and 0.0020-0.3274, respectively. The heterozygosity varied from 0.639 to 0.833. Discrimination power (DP) was 0.803-0.948, power of exclusion for trio-paternity was 0.416-0.584, power of exclusion for duo-paternity was 0.140-0.238, the polymorphism information content(PIC) was 0.57-0.81, respectively. The total discrimination power (TDP), cumulative probability of exclusion for trio-paternity testing(CPE-trio) and cumulative probability of exclusion for duo-paternity testing (CPE-duo) were 0.999 999 999 999 99, 0.999 999 883 211 752, and 0.987 266, respectively.
CONCLUSION
The 21 STR loci are highly polymorphic and informative in the studied population and can be employed as supplementary loci in duo-paternity testing or cases with variant circumstances.

Biomedical and Environmental Sciences 2021;34(6):425-438
Objective:
This study was aimed at examining the trends and correlates of physical activity (PA) and sedentary behaviors among Chinese children.
Methods:
A total of 4,341 subjects (6,936 observations) aged 6-17 years who participated in the China Health and Nutrition Survey (2004-2015) were included. Of the subjects, 41% participated in the survey twice or more. Random-effects ordinal regression models and repeated-measures mixed-effects models were used to examine the PA trends. Quantile regression models were applied to examine the factors influencing PA and sedentary behaviors.
Results:
From 2004 to 2015, the prevalence of physical inactivity among Chinese children aged 6-17 years increased by 5.5% [odds ratio (
Conclusions
A declining PA trend among Chinese children aged 6-17 years was observed from 2004 to 2015, and certain subgroups and geographical areas are at higher risk of physical inactivity.
