The aberrant epigenetic reprogramme is an important cause for abnormal development of nuclear transfer embryos. The objective of this study was to investigate the CpG island methylation profiles and relative expression levels of H19 gene in different tissues of cloned goat fetus. We detected liver, placenta, kidney, lung and heart in the dead cloned goat fetus and the age-matched normal goat fetus (control) by using bisulfite sequencing and real time PCR. Results indicated that methylation levels of the fifth CpG island of H19 gene in dead cloned goat fetus was significant high compared with that in the control in placenta (70% vs 49.41%, P < 0.05), and relative expression levels of H19 gene was significant low compared with that in the control (883.3 vs 1 264.5, P < 0.05). Reversely, the methylation levels was significant low compared with that in the control in lung (63.53% vs 88.24%, P < 0.05), and relative expression levels was significant high compared with that in the control (1 003.4 vs 515.5, P < 0.05). The differences of others groups were insignificant (P > 0.05). Results showed the abnormal DNA methylation proflies of H19 gene occurred in some tissues of cloned goat fetus, which affected normal expression levels of H19 gene, indicating that aberrant DNA methylation reprogramme may be one of the important factors for the death of cloned animals.

Objective This study examined the research status and development process of FU Qingzhu’s Obstetrics and Gynecology (Fu Qing Zhu Nv Ke,《傅青主女科》, FQZNK) in the past 40 years with bibliometrics and visual analysis. Methods Retrieved all related literature in the research field of FQZNK from the domestic and foreign databases: China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Wanfang Database, and Web of Science (WOS) core database, including Science Citation Index Expanded (SCIE), Social Sciences Citation Index (SSCI), and Arts & Humanities Citation Index (A&HCI). The search range was from January 1, 1980 to March 10, 2021. In addition, bibliometrics and CiteSpace 5.7.R2 software were used to analyze literature types, published journals, cited literature, the number of author publications, co-author networks, co-institution networks, keyword co-occurrence networks, keyword clusters, and keyword bursts. Results A total of 678 valid records were included in the final dataset. Literature types, high publication journals, highly cited literature, high-yield institutions, high-yield research teams, and high-productivity scholars in this research field were found through bibliometrics. Literature types can be divided into four categories, among which 451 are theoretical studies on academic thoughts of FQZNK, accounting for 66.5% of the included journals. The Journal of Shanxi Traditional Chinese Medicine had the largest volume of published articles (61), accounting for 9.0% of the total number of the included journals. The most cited literature was ZHOU Mingxin’s article “Using the quantitative method to discuss author’s authenticity and formula characteristics of FU Qingzhu’s Obstetrics and Gynecology”, which was cited 94 times. Hunan University of Chinese Medicine, the institution with the most publications, published 45 articles, and YOU Zhaoling, the most published author, published 33 articles. Moreover, it was found that most high-yield researchers came from high-yield institutions and that Hunan University of Chinese Medicine had the most research on FQZNK. Keyword co-occurrence analysis revealed that the keyword “FQZNK” had the highest frequency (597 times) and the highest centrality (1.00). Keyword cluster analysis used the Log-Likelihood Ratio (LLR) algorithm to form eleven important clusters: #0 treatment aiming at its root causes, #1 gynecopathy, #2 Siwu Decoction (四物汤), #3 FU Qingzhu, #4 post-partum, #5 infertility, #6 dysmenorrhea, #7 sterility, #8 coordinate the heart and kidney, #9 Danggui Buxue Decoction (当归补血汤), and #10 treatment. It was found that the prescriptions of FQZNK were studied mainly before 2000, the theoretical studies were mainly conducted before 2010, and its clinical application was mainly explored from 2010 until now. Diseases such as dysmenorrhea, morbid vaginal discharge, infertility, metrorrhagia, and polycystic ovarian syndrome (PCOS) have recently become popular topics in this field. Conclusion The current study provides more scientific, accurate, and comprehensive scientific support for further research and development of traditional Chinese medicine (TCM) in FQZNK. With this foundation, people can use burst detection to ascertain the current hotspots in research, get their development trends, and forecast future research directions. In addition, infertility, morbid vaginal discharge, flooding, and PCOS treatments based on TCM syndrome differentiation are currently popular research topics for FQZNK.

OBJECTIVE:To study the effects of Modified liuwei dihuang decoction on kidney/bone injury of chronic kidney disease-mineral and bone disorder(CKD-MBD)model rats. METHODS :The male SD rats were randomly divided into normal group(n=10),high phosphorus group (n=30),model group (n=30),calcitriol group (positive control ,0.09 μg/kg,n=30), Modified liuwei dihuang decoction group (10 g/kg by crude drug ,n=30). CKD-MBD model was established by high phosphorus and adenine diet for 6 weeks. After modeling ,normal group and model group were given normal diet/high phosphorus diet and intragastric administration of water. Administration groups were fed with normal diet and given corresponding solution intragastrically(water as solvent ),0.1 mL/kg,once a day ,for consecutive 6 weeks. Blood sample of rats in the normal group were collected ,and they were sacrificed after the last administration. Blood sample of 10 rats in each other group were collected , and they were sacrificed at 2,4 and 6 weeks after administration. The contents of blood urea nitrogen (BUN),serum creatinine (Scr),calcium,phosphorus,iPTH,FGF-23,RANKL and osteocalcin in serum were detected in each group. The bone mineral density(BMD)of femoral was measured ,the morphological changes of renal tissue and bone tissue were observed ,and the percentage of renal tubular injury and the score of renal interstitial fibrosis were calculated. RESULTS :Compared with normal group,above indexes in high phosphorus group had no significant change at different time points (P>0.05). There was no abnormal change in renal/bone tissue. Compared with high phosphorus group at the same time point ,the contents of BUN ,Scr, phosphorus,iPTH,FGF-23,RANKL and osteocalcin in serum ,the percentage of renal tubular injury and the score of renal interstitial fibrosis in the model group were significantly increased ,while the contents of calcium in serum and the BMD of femoral were significantly decreased (P<0.05 or P<0.01). The renal tissue showed diffuse fibrosis. The width of trabecular bone was increased and the number of osteoblasts was decreased. Compared with the model group at the same time point ,the contents of BUN(except for Modified liuwei dihuang decoction group after 2 weeks of administration ),Scr,serum phosphorus ,iPTH, FGF-23,RANKL and osteocalcin ,the percentage of renal tubular injury and the score of renal interstitial fibrosis in Modified liuwei dihuang decoction group and calcitriol group were decreased significantly at each time point ;serum calcium content and BMD(except for 2 weeks of administration )were significantly increased (P<0.05 or P<0.01),and the pathological changes of renal/bone tissue were significantly improved ;there was no statistical significance in above indexes between Modified liuwei dihuang decoction group and calcitriol group (P>0.05). CONCLUSIONS :Modified liuwei dihuang decoction can improve kidney/ bone injury of CKD-MBD model rats ,and improve BMD and regulate disorder of calcium and phosphorus metabolism.

Due to the virtues of no stutter peaks, low rates of mutation, and short amplicon sizes, insertion/deletion (InDel) polymorphism is an indispensable tool for analyzing degraded DNA samples from crime scenes for human identifications (Wang et al., 2021). Herein, a self-developed panel of 43 InDel loci constructed previously by our group was utilized to evaluate the genetic diversities and explore the genetic background of the Han Chinese from Beijing (HCB) including 301 random healthy individuals. The lengths of amplicons at 43 InDel loci in this panel ranged from 87 to 199 bp, which indicated that the panel could be used as an effective tool to utilize highly degraded DNA samples for human identity testing. The loci in this panel were validated and performed well for forensic degraded DNA samples (Jin et al., 2021). The combined discrimination power (PD) and combined probability of exclusion (PE) values in this panel indicated that the 43 InDel loci could be used as the candidate markers in personal identification and parentage testing of HCB. In addition, population genetic relationships between the HCB and 26 reference populations from five continents based on 19 overlapped InDel loci were displayed by constructing a phylogenetic tree, principal component analysis (PCA), and population genetic structure analysis. The results illustrated that the HCB had closer genetic relationships with the Han populations from Chinese different regions.
