Role of enriched environment in the model of maternal separation / 中国儿童保健杂志

Early life stress in humans can affect the normal development of individual neural networks, ultimately leading to diseases such as anxiety, depression, and autism in such children. The maternal separation model is commonly used to study the effects of early adverse experiences in human infants. Studies have shown that maternal separation in mice can lead to anxiety, depression, and impairments in spatial learning and memory in young mice during adulthood. However, enriched environmental interventions have been found to ameliorate the negative outcomes of early life stress by exerting a range of beneficial effects. This article provides an overview of the positive effects of enriched environmental interventions on mice in the maternal separation model.

The Influence of Shoutai Wan （寿胎丸） on Lactic Acid Content at the Maternal-Fetal Interface and Expression of Immune-Related Factors in Recurrent Miscarriage Model Mice / 中医杂志

ObjectiveTo explore the possible mechanisms of Shoutai Wan （寿胎丸） in treating recurrent miscarriage （RSA） from the perspective of immune tolerance under the acidic microenvironment at the maternal-fetal interface. MethodsFemale CBA/J mice were randomly divided into normal group， model group， progesterone group， and Shoutai Wan group， with 15 mice in each group. The mice in the normal group and model group were given 0.2 ml distilled water by gavage each day， the Shoutai Wan group given Shoutai Wan decoction 0.15 g/（10 g·d） by gavage， the progesterone group given progesterone tablets 0.44 mg/（10 g·d） by gavage. After gavage for 14 days， the mice were cohabited. Female CBA/J mice in the normal group were mated with male BALB/c mice at a ratio of 2∶1， and female CBA/J mice in the other groups were mated with male DBA/2 mice at a ratio of 2∶1 to establish the RSA mouse model. Vaginal smears were taken from the female mice the next morning， and the appearance of a large number of spermatozoa and the presence of a vaginal plug were considered as the first day of pregnancy. After the appearance of the plug， the mice were continued to be administered according to the previous method until the 10th day of pregnancy. On the 10th day of pregnancy， maternal-fetal interface tissues were collected from each group of mice， and lactate dehydrogenase colorimetric method was used to detect lactate （LA） content； qPCR method and Western blot method were used to detect the expression of immune-related factors interleukin-4 （IL-4）， interferon-gamma （IFN-γ）， transforming growth factor beta 1 （TGF-β1）， and forkhead box protein 3 （Foxp3） mRNA and protein； flow cytometry was used to detect the numbers of helper T lymphocyte 1 （Th1）， helper T lymphocyte 2 （Th2）， regulatory T cell （Treg）， classical macrophage （M1）， and alternative macrophage （M2）. The bivariate Pearson test was used to analyze the correlation between LA content and the numbers of Th1， Th2， Treg， M1， and M2 cells， as well as the correlation between LA content and the expression of IL-4， IFN-γ， TGF-β1， Foxp3 protein， and mRNA. ResultsOn the 10th day of pregnancy， compared with the normal group， the LA content decreased in the model group， and the expression of IL-4， TGF-β1， Foxp3 protein and mRNA in the maternal-fetal interface tissues decreased， while the expression of IFN-γ protein and mRNA increased. The numbers of Th1 and M1 cells increased， while the numbers of Th2， Treg， and M2 cells decreased （P＜0.05 or P＜0.01）. Compared with the model group， the LA content increased in the Shoutai Wan group and progesterone group. The expression of IL-4， TGF-β1， Foxp3 protein and mRNA in the maternal-fetal interface tissues increased， while the expression of IFN-γ protein and mRNA decreased. The numbers of Th1 and M1 cells decreased， while the numbers of Th2， Treg， and M2 cells increased （P＜0.05 or P＜0.01）. The LA content was positively correlated with the numbers of Th2， Treg， and M2 cells， and the expression of IL-4， TGF-β1， Foxp3 protein， and mRNA （P＜0.05 or P＜0.01）； the LA content was negatively correlated with the numbers of Th1， M1 cells， and the expression of IFN-γ protein and mRNA （P＜0.05 or P＜0.01）. ConclusionShoutai Wan may improve immune tolerance by regulating the expression of immune-related factors in the acidic microenvironment at the maternal-fetal interface of RSA model mice， thereby exerting its role in preventing miscarriage.

Exploration of “Burnt Needle” and “Red-hot Needling” in the Inner Canon of Yellow Emperor （《黄帝内经》） / 中医杂志

“Burnt needle” and “red-hot needling” are both mentioned in the Inner Canon of Yellow Emperor （《黄帝内经》）， although they possess distinct characteristics and are not identical. Subsequent generations have erroneously employed them as interchangeable with “fire needles”， which is an incorrect designation. This article mostly relies on the original text of the Inner Canon of Yellow Emperor and provides an interpretation of their significances as follows： “burnt needle” is a broad phrase referring to needles that have been intentionally burned in order to heat them； the term “burnt needle and rapid needling” can be more accurately described as “the act of rapidly puncturing with a needle， without burning the needle if the disease exhibits hot characteristics， but requiring burning if the disease exhibits cold characteristics， and it is appropriate to puncture rapidly before burning the needle”. “Red-hot needling” refers to the process of first burning the needle and then puncturing with it， which is specific. This paper clarified the origins and differences among burnt needles， red-hot needling， red-hot needle， burning needle， warm needles and fire needle， pointing out the doctrinal diagnostic and therapeutic system based on “burnt Needle” and “red-hot needling”， can be a track for the integration of acupuncture and moxibustion.

Research Progress on the Effect of Abnormal Thyroid Function on the Coagulation System and the Interaction of Therapeutic Drugs / 医药导报

For patients with abnormal thyroid function,the detection of peripheral blood coagulation indicators may be irregular,and there is a potential risk of thrombosis or bleeding.Patients with hyperthyroidism have significant endothelial dysfunction and risk of thrombosis.However,the reports on the effect of hypothyroidism on coagulation function are still controversial.The potential risk of abnormal thyroid function to the coagulation system may interfere with the safety of anticoagulant therapy,and the interaction between thyroid disease treatment drugs and anticoagulant drugs also affects the safety of the patient's medication.Therefore,this article is based on previous research literature,analyzes the correlation between abnormal thyroid function and coagulation function,and evaluates and discusses the impact of abnormal thyroid function on the coagulation system and related therapeutic drug interactions.It is expected to provide a reference for diagnosing and treating patients with thyroid dysfunction and abnormal coagulation function.

Recent advances in small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase / 药学学报

Influenza virus causes serious threat to human life and health. Due to the inherent high variability of influenza virus, clinically resistant mutant strains of currently approved anti-influenza virus drugs have emerged. Therefore, it is urgent to develop antiviral drugs with new targets or mechanisms of action. RNA-dependent RNA polymerase is directly responsible for viral RNA transcription and replication, and plays key roles in the viral life cycle, which is considered an important target of anti-influenza drug design. From the point of view of medicinal chemistry, this review summarizes current advances in diverse small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase, hoping to provide valuable reference for development of novel antiviral drugs.

Single-shot AAV-vectored vaccine against SARS-CoV-2 with fast and long-lasting immunity

Due to the insufficient long-term protection and significant efficacy reduction to new variants of current COVID-19 vaccines, the epidemic prevention and control are still challenging. Here, we employ a capsid and antigen structure engineering (CASE) strategy to manufacture an adeno-associated viral serotype 6-based vaccine (S663V-RBD), which expresses trimeric receptor binding domain (RBD) of spike protein fused with a biological adjuvant RS09. Impressively, the engineered S663V-RBD could rapidly induce a satisfactory RBD-specific IgG titer within 2 weeks and maintain the titer for more than 4 months. Compared to the licensed BBIBP-CorV (Sinopharm, China), a single-dose S663V-RBD induced more endurable and robust immune responses in mice and elicited superior neutralizing antibodies against three typical SARS-CoV-2 pseudoviruses including wild type, C.37 (Lambda) and B.1.617.2 (Delta). More interestingly, the intramuscular injection of S663V-RBD could overcome pre-existing immunity against the capsid. Given its effectiveness, the CASE-based S663V-RBD may provide a new solution for the current and next pandemic.

Genomic epidemiology of Vibrio parahaemolyticus from acute diarrheal patients in Shenzhen City from 2013 to 2021 / 中华预防医学杂志

Objective: To characterize the prevalence and genomic epidemiology of Vibrio parahaemolyticus from acute diarrheal patients in Shenzhen City from 2013 to 2021. Methods: Based on the Shenzhen Infectious Diarrhea Surveillance System, acute diarrheal patients were actively monitored in sentinel hospitals from 2013 to 2021. Whole-genome sequencing (WGS) of Vibrio parahaemolyticus isolates was performed, and the genomic population structure, serotypes, virulence genes and multilocus sequence typing were analyzed. Outbreak clusters from 2019 to 2021 were explored based on single-nucleotide polymorphism analysis. Results: A total of 48 623 acute diarrhea cases were monitored in 15 sentinel hospitals from 2013 to 2021, and 1 135 Vibrio parahaemolyticus strains were isolated, with a positive isolation rate of 2.3%. Qualified whole-genome sequencing data of 852 isolates were obtained. Eighty-nine serotypes, 21 known ST types and 5 new ST types were identified by sequence analysis, and 93.2% of strains were detected with toxin profile of tdh+trh-. 8 clonal groups (CGs) were captured, with CG3 as the absolute predominance, followed by CG189. The CG3 group was dominated by O3:K6 serotype and ST3 sequence type, while CG189 group was mainly O4:KUT, O4:K8 serotypes and ST189a and ST189 type. A total of 13 clusters were identified, containing 154 cases. About 30 outbreak clusters with 29 outbreak clusters caused by CG3 strains from 2019 to 2021. Conclusion: Vibrio parahaemolyticus is a major pathogen of acute infectious diarrhea in Shenzhen City, with diverse population structures. CG3 and CG189 have been prevalent and predominant in Shenzhen City for a long time. Scattered outbreaks and persistent sources of contamination ignored by traditional methods could be captured by WGS analysis. Tracing the source of epidemic clone groups and taking precise prevention and control measures are expected to significantly reduce the burden of diarrhea diseases caused by Vibrio parahaemolyticus infection in Shenzhen City.

Preface to the special issue: biotechnology of plastic waste degradation and valorization / 生物工程学报

Synthetic plastics have been widely used in various fields of the national economy and are the pillar industry. However, irregular production, plastic product use, and plastic waste piling have caused long-term accumulation in the environment, contributing considerably to the global solid waste stream and environmental plastic pollution, which has become a global problem to be solved. Biodegradation has recently emerged as a viable disposal method for a circular plastic economy and has become a thriving research area. In recent years, important breakthroughs have been made in the screening, isolation, and identification of plastic-degrading microorganisms/enzyme resources and their further engineering, which provide new ideas and solutions for treating microplastics in the environment and the closed-loop bio-recycling of waste plastics. On the other hand, the use of microorganisms (pure cultures or consortia) to further transform different plastic degradants into biodegradable plastics and other compounds with high added value is of great significance, promoting the development of a plastic recycling economy and reducing the carbon emission of plastics in their life cycle. We edited a Special Issue on the topic of "Biotechnology of Plastic Waste Degradation and Valorization", focusing on the researches progress in three aspects: Mining microbial and enzyme resources for plastic biodegradation, Design and engineering of plastic depolymerase, and biological high-value transformation of plastic degradants. In total, 16 papers have been collected in this issue including reviews, comments, and research articles, which provide reference and guidance for further development of plastic waste degradation and valorization biotechnology.

Advances in methods for detecting plastics biodegradation / 生物工程学报

The pollution caused by improper handling of plastics has become a global challenge. In addition to recycling plastics and using biodegradable plastics, an alternative solution is to seek efficient methods for degrading plastics. Among them, the methods of using biodegradable enzymes or microorganisms to treat plastics have attracted increasing attention because of its advantages of mild conditions and no secondary environmental pollution. Developing highly efficient depolymerizing microorganisms/enzymes is the core for plastics biodegradation. However, the current analysis and detection methods cannot meet the requirements for screening efficient plastics biodegraders. It is thus of great significance to develop rapid and accurate analysis methods for screening biodegraders and evaluating biodegradation efficiency. This review summarizes the recent application of various commonly used analytical techniques in plastics biodegradation, including high performance liquid chromatography, infrared spectroscopy, gel permeation chromatography, and determination of zone of clearance, with fluorescence analysis techniques highlighted. This review may facilitate standardizing the characterization and analysis of plastics biodegradation process and developing more efficient methods for screening plastics biodegraders.

Synthesis, biodegradation and waste disposal of polylactic acid plastics: a review / 生物工程学报

With the escalation of plastic bans and restrictions, bio-based plastics, represented by polylactic acid (PLA), have become a major alternative to traditional plastics in the current market and are unanimously regarded as having potential for development. However, there are still several misconceptions about bio-based plastics, whose complete degradation requires specific composting conditions. Bio-based plastics might be slow to degrade when it is released into the natural environment. They might also be harmful to humans, biodiversity and ecosystem function as traditional petroleum-based plastics do. In recent years, with the increasing production capacity and market size of PLA plastics in China, there is an urgent need to investigate and further strengthen the management of the life cycle of PLA and other bio-based plastics. In particular, the in-situ biodegradability and recycling of hard-to-recycle bio-based plastics in the ecological environment should be focused. This review introduces the characteristics, synthesis and commercialization of PLA plastics, summarizes the current research progress of microbial and enzymatic degradation of PLA plastics, and discusses their biodegradation mechanisms. Moreover, two bio-disposal methods against PLA plastic waste, including microbial in-situ treatment and enzymatic closed-loop recycling, are proposed. At last, the prospects and trends for the development of PLA plastics are presented.

Advances in biotransformation of methanol into chemicals / 生物工程学报

Methanol has become an attractive substrate for the biomanufacturing industry due to its abundant supply and low cost. The biotransformation of methanol to value-added chemicals using microbial cell factories has the advantages of green process, mild conditions and diversified products. These advantages may expand the product chain based on methanol and alleviate the current problem of biomanufacturing, which is competing with people for food. Elucidating the pathways involving methanol oxidation, formaldehyde assimilation and dissimilation in different natural methylotrophs is essential for subsequent genetic engineering modification, and is more conducive to the construction of novel non-natural methylotrophs. This review discusses the current status of research on methanol metabolic pathways in methylotrophs, and presents recent advances and challenges in natural and synthetic methylotrophs and their applications in methanol bioconversion.

New drug for thyroid-associated ophthalmopathy——Teprotumumab-trbw / 国际眼科杂志(Guoji Yanke Zazhi)

Teprotumumab-trbw,a monoclonal antibody that acts on the insulin growth factor-Ⅰ receptor, was approved in 2020 for the treatment of thyroid-associated ophthalmopathy, but little is known about it in China. It is hoped to provide guidance for clinical use through the review of its molecular structure, pharmacokinetics, therapeutic mechanism, clinical research and safety. It inhibits immune inflammation by blocking thyroid-stimulating hormone receptor /insulin growth factor-Ⅰ receptor crosstalk signaling, so as to reduce the production of hyaluronic acid and inflammatory factors in response. It can also promote the apoptosis of retro-orbital fibroblasts/adipocytes and inhibit the expression of genes related to the synthesis of thyroid hormones, thereby significantly improving the clinical symptoms such as exophthalmos and diplopia. The common adverse reactions of Teprotumumab-trbw are muscle spasm, hyperglycemia, hearing loss and so on. Teprotumumab-trbw is effective and durable in the treatment of thyroid-associated ophthalmopathy, and patients with secondary treatment can also benefit from it, which provides a new way and hope for the treatment of thyroid-associated ophthalmopathy.
