Double investigation of gene therapy / 中国医学伦理学

From the biological point of view,genes are the key to being human.With the continuous advancement of human gene technology,gene therapy has become a frontier topic with great vitality and controversy in the field of life science:it has brought more hope for the cure of diseases to human beings,but it has also triggered many ethical debates.This paper sorts out the ethical questions faced by gene therapy,extracts the challenges faced by individual rights,social justice,natural order and so on,and responds one by one,which shows that the development of gene therapy does not violate these ethical values in principle.However,the occurrence of gene editing events has sounded the alarm for us:where should the implementation boundary of gene therapy be?Through the comparative analysis of the gene editing incident and the Berlin patient case,the article points out that the study of technical safety is the key to safe application of gene therapy in clinical applications.

A panel study on the effect of atmospheric PM2.5 exposure on the gut microbiome in healthy elderly people aged 60-69 years old / 中华预防医学杂志

Objective: To analyze the short-term effect of individual atmospheric PM2.5 exposure on the diversity, enterotype, and community structure of gut microbiome in healthy elderly people in Jinan, Shandong province. Methods: The present panel study recruited 76 healthy elderly people aged 60-69 years old in Dianliu Street, Lixia District, Jinan, Shandong Province, and followed them up five times from September 2018 to January 2019. The relevant information was collected by questionnaire, physical examination, precise monitoring of individual PM2.5 exposure, fecal sample collection and gut microbiome 16S rDNA sequencing. The Dirichlet multinomial mixtures (DMM) model was used to analyze the enterotype. Linear mixed effect model and generalized linear mixed effect model were used to analyze the effect of PM2.5 exposure on gut microbiome α diversity indices (Shannon, Simpson, Chao1, and ACE indices), enterotype and abundance of core species. Results: Each of the 76 subjects participated in at least two follow-up visits, resulting in a total of 352 person-visits. The age of 76 subjects was (65.0±2.8) years old with BMI (25.0±2.4) kg/m2. There were 38 males accounting for 50% of the subjects. People with an educational level of primary school or below accounted for 10.5% of the 76 subjects, and those with secondary school and junior college or above accounting for 71.1% and 18.4%. The individual PM2.5 exposure concentration of 76 subjects during the study period was (58.7±53.7) μg/m3. DMM model showed that the subjects could be divided into four enterotypes, which were mainly driven by Bacteroides, Faecalibacterium, Lachnospiraceae, Prevotellaceae, and Ruminococcaceae. Linear mixed effects model showed that different lag periods of PM2.5 exposure were significantly associated with a lower gut α diversity index (FDR<0.05 after correction). Further analysis showed that PM2.5 exposure was significantly associated with changes in the abundances of Firmicutes (Megamonas, Blautia, Streptococcus, etc.) and Bacteroidetes (Alistipes) (FDR<0.05 after correction). Conclusion: Short-term PM2.5 exposure is significantly associated with a decrease in gut microbiome diversity and changes in the abundance of several species of Firmicutes and Bacteroidetes in the elderly. It is necessary to further explore the underlying mechanisms between PM2.5 exposure and the gut microbiome, so as to provide a scientific basis for promoting the intestinal health of the elderly.

Health risk assessment of exogenous harmful pollutants in Chinese medicine: a review / 中国中药杂志

In recent years, the quality and safety problems have been limiting the internationalization of Chinese medicine. The pollutants in Chinese medicine, particularly the exogenous harmful pollutants mainly including mycotoxins, pesticide residues, heavy metals, harmful elements, and sulfur dioxide, are of high risks for people. Therefore, the World Health Organization(WHO) and relevant national organizations have clearly defined the maximum residue limits(MRLs) of such pollutants. Chinese Pharmacopoeia(2020 edition, volume Ⅳ) also demonstrates the detection methods, MRLs and preliminary risk assessment methods for four typical exogenous harmful pollutants in Chinese medicine. Therefore, continuous optimization of the health risk assessment system can further help further raise the quality and safety of Chinese medicine. This paper reviews the research on the health risk assessment of four typical exogenous harmful pollutants in Chinese medicine and discusses the problems of and challenges for the assessment system, which is expected to lay a scientific basis for the establishment of the risk warning mode and response measures suitable for specific types of Chinese medicine.

Clinical characteristics of crystal deposits in joints and tendons in patients with gout / 北京大学学报(医学版)

OBJECTIVE@#To explore the abnormal manifestations and clinical features of patients with gout according to the location of crystal deposits: in articulars or in tendons.@*METHODS@#A total of 105 patients with gout who were continuously treated in the Department of Rheumatology and Immunology of Peking University People's Hospital from June 2019 to December 2019 were selected and their knees, ankles, toes and painful joints and tendons were examined by high-frequency ultrasound. Then we grouped them according to the presence or absence of sodium urate crystals and the location of the crystals, collected their clinical data, and analyzed the clinical characteristics.@*RESULTS@#Among the 105 patients, 25 patients had no crystal deposits in the joints or tendons (as the non-crystal group), 43 patients had intra-articular crystals (as the joint group), and 37 patients had intra-tendon crystals with or without intra-articular crystals (as the tendon group). Among them, the most involved part of sodium urate crystals deposited in the joints was the metatarsophalangeal joint (29 cases, 67.4%), followed by knee joints (10 cases, 23.2%), ankle joints (9 cases, 20.9%). The most involved part of sodium urate crystals deposited in the tendon was the quadriceps tendon (16 cases, 43.2%), followed by the Achilles tendon (13 cases, 35.1%), the patellar tendon (12 cases, 32.4%), and the three heads of brachii tendons (5 cases, 13.5%). The three groups were compared using multi-sample analysis of variance/multi-sample rank sum test. Age, age of first increase in uric acid (UA), serum glucose (Glu) level and C reactive protein (CRP) were all significantly different. After multiple comparisons, compared with the non-crystal group, age, the age of first increase in uric acid, and CRP were significantly higher in the tendon group. There was no significant difference between the non-crystal group and the joint group. There was no significant difference between the tendon group and the joint group.@*CONCLUSION@#In patients with gout, it is common for ultrasound to find crystals deposited in joints or tendons. The most commonly affected parts include the metatarsophalangeal joint, knee joint, ankle joint, quadriceps tendon, Achilles tendon, patellar tendon, and triceps tendon. There were significant differences among the three groups in age, age of first increase in uric acid, CRP and blood glucose, and the proportion of urinary calculi in patients with crystal deposits was significantly higher than those without crystal deposits.

Clinical observation of deep electroacupuncture at Baliao points for female stress urinary incontinence / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of deep electroacupuncture (EA) at Baliao points in treating stress urinary incontinence (SUI). Methods: A total of 60 female patients with SUI were divided into two groups according to the order of consultation, with 30 cases in each group. The control group was treated with pelvic floor muscle training. The treatment group was treated with deep EA at Baliao points [Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33) and Xialiao (BL 34)]. Results: The total effective rate was 93.3％ in the treatment group, versus 33.3％ in the control group, and the total effective rate of the treatment group was significantly higher than that of the control group (P<0.05). After treatment, the scores of international consultation on incontinence questionnaire-short form (ICIQ-SF) and the volume of urinary leakage in both groups were lower than those before treatment (all P<0.05), and the ICIQ-SF score and the volume of urinary leakage in the treatment group were lower than those in the control group (both P<0.05). Conclusion: Deep EA at Baliao points with long needles can improve the clinical symptoms in female patients with SUI, and it has a better curative effect than pelvic floor muscle training.

The role and mechanism of leucyl-tRNA synthetase in the regulation of protein synthesis in aging skeletal muscle / 生理学报

The imbalance of protein metabolism is the major cause of skeletal muscle atrophy, and the decrease of protein synthesis directly leads to the occurrence and development of age-related sarcopenia. The canonical role of leucyl-tRNA synthetase (LeuRS) is ligating leucine to the cognate tRNA, and thus it plays a central role in genetic coding. With the further studies of LeuRS in recent years, LeuRS has been found to control protein homeostasis in aging skeletal muscle via its non-canonical role. In this paper, we reviewed the structure and biological features of aminoacyl-tRNA synthetase and LeuRS, and summarized the recent advances in studies on the effects of LeuRS in regulating aging skeletal muscle protein synthesis as an intracellular leucine sensor. Moreover, we also analyzed the potential role of LeuRS in activation of mammalian target of rapamycin complex 1 (mTORC1) signaling transduction pathway in response to anabolic stimuli such as exercise and amino acids ingestion. This paper may provide some new ideas for the prevention, diagnosis and treatment of age-related sarcopenia.

The rats in group F, G and H were treated with the extracts of Acorus tatarinowii Schott at the doses of 0.12, 1.20 and 4.80 g. kg by ig. Learning and memory of rats were tested by the method of water maze experiment, and the expression levels of p-ERK1/2 and p-CREB protein in hippocampus of rats were tested by the method of Western blot in the end of the experiment.@*RESULTS@#The escape latencies of E and H groups were lower than those of groups B, C, D, F and G; and the numbers of plateau crossing were more than those of groups B, C, D, F and G and the expression levels of p-ERK1/2, p-CREB protein were higher than those of groups B, C, D, F and G , respectively(P ＜ 0.01). There was no significant difference in the above indexes among groups A, E and H(P＞0.05) except that the expression levels of p-ERK2 protein in group E were lower than those in group A and H (P＜0.05).@*CONCLUSION@#Acorus tatarinowii and its active component- HMF can improve the learning and memory of rats with exercise-induced fatigue, and the mechanism is related to the up-regulation of ERK / CREB signal in hippocampus of rats with exercise-induced fatigue.
