BACKGROUND:
The transcription factor POU2F1 regulates the expression levels of microRNAs in neoplasia. However, the miR-29b1/a cluster modulated by POU2F1 in gastric cancer (GC) remains unknown.
METHODS:
Gene expression in GC cells was evaluated using reverse-transcription polymerase chain reaction (PCR), western blotting, immunohistochemistry, and RNA in situ hybridization. Co-immunoprecipitation was performed to evaluate protein interactions. Transwell migration and invasion assays were performed to investigate the biological behavior of GC cells. MiR-29b1/a cluster promoter analysis and luciferase activity assay for the 3'-UTR study were performed in GC cells. In vivo tumor metastasis was evaluated in nude mice.
RESULTS:
POU2F1 is overexpressed in GC cell lines and binds to the miR-29b1/a cluster promoter. POU2F1 is upregulated, whereas mature miR-29b-3p and miR-29a-3p are downregulated in GC tissues. POU2F1 promotes GC metastasis by inhibiting miR-29b-3p or miR-29a-3p expression in vitro and in vivo . Furthermore, PIK3R1 and/or PIK3R3 are direct targets of miR-29b-3p and/or miR-29a-3p , and the ectopic expression of PIK3R1 or PIK3R3 reverses the suppressive effect of mature miR-29b-3p and/or miR-29a-3p on GC cell metastasis and invasion. Additionally, the interaction of PIK3R1 with PIK3R3 promotes migration and invasion, and miR-29b-3p , miR-29a-3p , PIK3R1 , and PIK3R3 regulate migration and invasion via the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway in GC cells. In addition, POU2F1 , PIK3R1 , and PIK3R3 expression levels negatively correlated with miR-29b-3p and miR-29a-3p expression levels in GC tissue samples.
CONCLUSIONS
The POU2F1 - miR-29b-3p / miR-29a-3p-PIK3R1 / PIK3R1 signaling axis regulates tumor progression and may be a promising therapeutic target for GC.

Objective:To explore the clinical phenotype and genetic basis of a child with Neutral lipid storage disease with myopathy (NLSDM).Methods:A child who was admitted to the First Affiliated Hospital of Zhengzhou University in February 2021 for a history of elevated creatine kinase (CK) for over 2 months was selected as the study subject. Clinical and laboratory examinations were carried out, and the child was subjected to whole exome sequencing. Candidate variants were validated by Sanger sequencing of her family members.Results:The patient, a 9-year-old female, had exhibited weakness in the lower limbs, elevated CK level, and refractory cardiomyotrophy. Genetic testing revealed that she has harbored c. 32C>G (p.S11W) and c. 516C>G (p.N172K) compound heterozygous variants of the PNPLA2 gene, which were respectively inherited from her mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were rated as likely pathogenic (PM1+ PM2_Supporting+ PP3+ PP4). Conclusion:The c. 32C>G (p.S11W) and c. 516C>G (p.N172K) compound heterozygous variants of the PNPLA2 gene probably underlay the myasthenia gravis and elevated creatine kinase in this child.

Protein arginine methylation is an important post-translational modification (PTM) mediated by protein arginine methyltransferase (PRMTs), which is closely related to the occurrence and development of many diseases. Methylation of arginine is closely related to inflammatory diseases and fracture healing. Decreased expression of PRMTs can lead to delayed or even non-healing of fractures. Both PRMT5 and PRMT6 play an important role in fracture healing and are closely related to the PI3K-AKT and NF-κB pathways. Exploration the relationship between protein arginine methylation and fracture healing can provide a new way to prevent delayed or even non-healing fracture.

SARS-CoV-2 may have potential effects on the male reproductive system. Evidence has shown that SARS-CoV-2 is not likely to transmit through sexual intercouse. However, male infected with SARS-CoV-2 may experience sexual dysfunction, semen quality decline, testicular damage and abnormal sex hormones. The extent and duration of these damages are still unclear, and further multidimensional research is necessary.

Objective:To summarize the clinical features, treatments and prognoses of aggressive natural killer cell leukemia (ANKL) in children.Methods:Clinical data and follow-up results were retrospectively reviewed for one hospitalized case of ANKL in June 2019.Through a literature search, the relevant items were retrieved from the databases of China National Knowledge Infrastructure, WanFang and PubMed using the Chinese and English keywords of "aggressive natural killer cell leukemia" and "children" up to December 2021.Results:This 8-year-old girl was diagnosed with ANKL by flow cytometric immunophenotype and immunohistochemical stain.Fever was the initial manifestation accompanied by sallow complexion, fatigue, enlargement of liver, spleen and lymph node and hematopenia of three lines.Allogeneic hematopoietic stem cell transplantation (allo-HSCT) was performed after chemotherapy.As of April 2022, the child stayed in a disease-free survival state after follow-ups for over 2 years.The literature search finally yielded 7 eligible Chinese and 10 English reports with a total of 17 pediatric ANKLs.In this group, there were fever (n=15), rash (n=1), perineal mass (n=1) and diarrhea, vomiting and other digestive tract symptoms (n=1). Six cases were misdiagnosed during an early stage of disease.4 cases received chemotherapy alone, 3 cases received chemotherapy regimen for acute lymphoblastic leukemia, 1 child died and one death occurred after received chemotherapy regimen of "cisplatin + vincristine + doxorubicin + ifosfamide". Allo-HSCT was performed in 5 patients after remission with chemotherapy and one child died from multiple organ failure at 9 months after allo-HSCT.Nine cases gave up treatment.Conclusions:ANKL has a rapid disease progression, diverse clinical manifestations, easy misdiagnosis and poor prognosis.For suspected ANKL cases, clinicians perform multiple bone perforations at multiple sites and immunophenotype by flow cytometry as soon as possible to confirm the diagnosis.Currently allo-HSCT offers a long-term survival of ANKL patients.

OBJECTIVE To establish a method for the determination of eriodictyol and luteolin in Xerochrysum braeteatum, and to evaluate their antioxidant activities in vitro. METHODS UPLC was used to investigate the coutent determination methodologically. Vitamin C and Trolox were used as the control, the IC50 values of eriodictyol and luteolin for scaving DPPH free radical were determined, and the antioxidant activity was compared. The kinetic characteristics of free radical scavenging reaction were preliminarily explained by the change of free radical scavenging rate within 4 h. RESULTS There was a good linear relationship (R=0.999 7) between the peak area and the concentration of eriodictyol in the range of 0.005 4-0.545 0 mg·mL-1 and luteolin in the range of 0.005 3-0.535 0 mg·mL-1. The precision, stability and recovery of the method were satisfactory. The scavenging ability of the 4 compounds from high to low was luteolin>eriodictyol>vitamin C>Trolox. Different from vitamin C and Trolox, the free radical scavenging process of eriodictyol and luteolin showed three stages:first fast and then slow. CONCLUSION The content determination method is simple and rapid, and can be used for the determination of eriodictyol and luteolin in Xerochrysum braeteatum. The resources of Xerochrysum braeteatum are worth further development because of their excellent antioxidant activities.

This study systematically and comprehensively sorted out the application status of Chinese patent medicines for the treatment of constipation in the clinic, to provide scientific evidence for future research directions and clinical drug use in this field. Based on the method of scoping review, the Chinese patent medicines for the treatment of constipation were retrieved from three drug lists to obtain the medicines that needed to be evaluated. A comprehensive and systematic search was carried out on the included studies on the treatment of constipation by Chinese patent medicines through eight Chinese and English databases, and the included studies were integrated and analyzed. The results were displayed in combination with charts. Thirty-four Chinese patent medicines and 118 studies were included in this study. According to the efficacies, Chinese patent medicines were divided into 4 categories, namely eliminating accumulation, purging fire, promoting Qi, and moistening bowels, involving 125 Chinese medicines. The overall attention of constipation research is on the rise. Marenwan (granules or soft capsules) gained the highest attention, with 42 studies, followed by Qirong Runchang oral liquid, with 21 studies, and Biantong tablets (capsules), with 19 studies. There are 10 studies on Congrong Tongbian oral liquid. Seventeen Chinese patent medicines had no corresponding clinical research. There were 8 study design types, and all drugs were mainly randomized controlled trials except Danggui Longhui pill. Among the intervention types, the comparison between Chinese patent medicines and western medicines was the most. The highest outcome indicators were efficacy, safety evaluation, and main symptoms or scores, and there was a lack of a unified core outcome indicator set. There were few studies on adverse reactions and the economy. Only 11.86% of the studies were funded. Clinically, Chinese patent medicines are widely used in the treatment of constipation, and the amount of related research shows an increasing trend. However, some Chinese patent medicines lack corresponding clinical evidence, and the published research has problems such as unrigorous design, ununified criteria for efficacy evaluation, lack of comprehensive evidence studies, and insufficient funds. It is hoped that more investment will be made in this field in the future, and more attention will be paid to drugs with relatively blank research and constipation syndromes with few treatments. Comprehensive evidence studies such as systematic reviews should be carried out actively. And the study design should be standardized to provide reliable evidence for the treatment of constipation with Chinese patent medicines.

ObjectiveTo evaluate the safety, efficacy, and economy of the four Chinese patent medicines (CPMs), including Simotang oral liquid, Liuwei Anxiao capsule, Baohe pill, and Jianwei Xiaoshi oral liquid in the treatment of functional dyspepsia (FD) by a rapid health technology assessment (RHTA), thus providing evidence support for clinical decision making. MethodChina National Knowledge Infrastructure (CNKI), WanFang Database, VIP Chinese Technology Periodical Database (VIP), China Biology Medicine disc (CBMdisc), PubMed, EMBASE, Cochrane Library, and Web of Science were searched by computer from inception to March 2022. After literature screening, data extraction, and quality evaluation, the descriptive analysis of the results combined with visual charts was performed. Nineteen studies were included, involving 18 randomized controlled trials (RCTs) and 1 Meta-analysis. Neither economic studies nor health technology assessment (HTA) reports were retrieved. ResultThe four CPMs were safe and effective in the treatment of FD, but economic research was lacking. Among them, Simotang oral liquid could be used for children with FD and FD caused by qi and food stagnation, liver and spleen disharmony, and liver and spleen stagnation. Liuwei Anxiao capsule could be used for adult patients with FD caused by food stagnation. Baohe pill could be used for the elderly with FD. Jianwei Xiaoshi oral liquid could be used for children with FD caused by spleen and stomach weakness. ConclusionThe four CPMs have their advantages in the treatment of FD. Among them, the clinical universality of Simotang oral liquid is higher. However, the quality of clinical evidence is generally low, and comparative analysis among drug dosage forms is lacking. In the future, it is necessary to improve, apply, and promote RHTA for rapid evidence production while carrying out a more standardized and scientific evidence-based demonstration of the comprehensive clinical efficacy of CPMs.

The impact of parental obesity on offspring health attracts increasing attention with the rising obese population worldwide. Much more studies have concentrated on the influences of maternal obesity, while studies regarding paternal obesity were relatively few and mainly focused on glucose and insulin regulation, adiposity, etc. Several large cohort studies and animal experiments have shown that paternal obesity can damage the neuropsychological development in offspring, which has become a risk factor for autistic spectrum disorders, cognitive disorders, and lower intelligence quotient, and epigenetic studies have explored the related mechanisms. This review summarizes the progress in this field, aiming to provide a reference for basic and clinical research in the future.
