During the development of therapeutic microRNAs (miRNAs or miRs), it is essential to define their pharmacological actions. Rather, miRNA research and therapy mainly use miRNA mimics synthesized in vitro. After experimental screening of unique recombinant miRNAs produced in vivo, three lead antiproliferative miRNAs against human NSCLC cells, miR-22-3p, miR-9-5p, and miR-218-5p, were revealed to target folate metabolism by bioinformatic analyses. Recombinant miR-22-3p, miR-9-5p, and miR-218-5p were shown to regulate key folate metabolic enzymes to inhibit folate metabolism and subsequently alter amino acid metabolome in NSCLC A549 and H1975 cells. Isotope tracing studies further confirmed the disruption of one-carbon transfer from serine to folate metabolites by all three miRNAs, inhibition of glucose uptake by miR-22-3p, and reduction of serine biosynthesis from glucose by miR-9-5p and -218-5p in NSCLC cells. With greater activities to interrupt NSCLC cell respiration, glycolysis, and colony formation than miR-9-5p and -218-5p, recombinant miR-22-3p was effective to reduce tumor growth in two NSCLC patient-derived xenograft mouse models without causing any toxicity. These results establish a common antifolate mechanism and differential actions on glucose uptake and metabolism for three lead anticancer miRNAs as well as antitumor efficacy for miR-22-3p nanomedicine, which shall provide insight into developing antimetabolite RNA therapies.

Primary ciliary dyskinesia (PCD) is a congenital, motile ciliopathy with pleiotropic symptoms. Although nearly 50 causative genes have been identified, they only account for approximately 70% of definitive PCD cases. Dynein axonemal heavy chain 10 (DNAH10) encodes a subunit of the inner arm dynein heavy chain in motile cilia and sperm flagella. Based on the common axoneme structure of motile cilia and sperm flagella, DNAH10 variants are likely to cause PCD. Using exome sequencing, we identified a novel DNAH10 homozygous variant (c.589C > T, p.R197W) in a patient with PCD from a consanguineous family. The patient manifested sinusitis, bronchiectasis, situs inversus, and asthenoteratozoospermia. Immunostaining analysis showed the absence of DNAH10 and DNALI1 in the respiratory cilia, and transmission electron microscopy revealed strikingly disordered axoneme 9+2 architecture and inner dynein arm defects in the respiratory cilia and sperm flagella. Subsequently, animal models of Dnah10-knockin mice harboring missense variants and Dnah10-knockout mice recapitulated the phenotypes of PCD, including chronic respiratory infection, male infertility, and hydrocephalus. To the best of our knowledge, this study is the first to report DNAH10 deficiency related to PCD in human and mouse models, which suggests that DNAH10 recessive mutation is causative of PCD.

Jingjin (muscle region of meridian) is a distal diagnosis and treatment system of the sinew/fascia disorders on the base of the concept of jin in TCM. Jin should be a particular palpable structure rather than a single anatomic structure with a specific distributing course. Yizhi weishu refers to a idea running through the whole process of diagnosis and treatment of sinew/fascia disorders, in which, the results, obtained by the overall observation and palpation of patient's sinew/fascia structure, are taken as the criteria of treatment. Yitong weishu (taking the sites of sensitivity or tenderness as the points) verifies this idea in practice. Under the guidance of yizhi weishu, through identifying the primary from the secondary, and regulating yin and yang, the spasticity and flaccidity of sinews/fascia can be cured and the induced diseases treated. The diagnosis and treatment system of jingjin, based on yizhi weishu, develops the original jingjin theory with vague concept involved, formulates a systematic thinking of treatment for sinew/fascia disorders and provides a new approach to clinical treatment.

OBJECTIVE: To investigate the anti-inflammatory activity of Radix Panacis quinguefolii root extract (RPQE) and its therapeutic effects on inflammatory bowel disease (IBD). METHODS: The 72-hour post-fertilization zebrafish was used to generate the local and systematic inflammation models through tail-amputation and lipopolysaccharide (LPS)-induction (100 µ g/mL), respectively. The Tg(zlyz:EGFP) zebrafish was induced with 75 µ g/mL 2,4,6-trinitrobenzene sulfonic acid (TNBS) for establishing the IBD model. The tail-amputated, LPS-, and TNBS-induced models were subjected to RPQE (ethanol fraction, 10-20 µ g/mL) administration for 12 and 24 h, respectively. Anti-inflammatory activity of RPQE was evaluated by detecting migration and aggregation of leukocytes and expression of inflammation-related genes. Meanwhile, TNBS-induced fish were immersed in 0.2% (W/V) calcein for 1.5 h and RPQE for 12 h before photographing to analyze the intestinal efflux efficiency (IEE). Moreover, the expression of inflammation-related genes in these fish was detected by quantitative polymerase chain reaction. RESULTS: Subject to RPQE administration, the migration and aggregation of leukocytes were significantly alleviated in 3 zebrafish models (P<0.01). Herein, RPQE ameliorated TNBS-induced IBD with respect to a significantly reduced number of leukocytes, improved IEE, and inhibited gene expression of pro-inflammatory factors (P<0.05 or P<0.01). CONCLUSION RPQE exhibited therapeutic effects on IBD by inhibiting inflammation.

The peeled stems of Syringa pinnatifolia(SP) is a representative Mongolian folk medicine with the effects of anti-depression, heat clearance, pain relief, and respiration improvement. It has been clinically used for the treatment of coronary heart disease, insomnia, asthma, and other cardiopulmonary diseases. As part of the systematic study on pharmacological substances of SP, 11 new sesquiterpenoids were isolated from the terpene-containing fractions of the ethanol extract of SP by liquid chromatography-mass spectrometry(LC-MS) and proton nuclear magnetic resonance(~1H-NMR) guided isolation methods. The planar structures of the sesquiterpenoids were identified by MS, 1D NMR, and 2D NMR data analysis, and were named pinnatanoids C and D(1 and 2), and alashanoids T-ZI(3-11), respectively. The structure types of the sesquiterpenoids included pinnatane, humulane, seco-humulane, guaiane, carryophyllane, seco-erimolphane, isodaucane, and other types. However, limited to the low content of compounds, the existence of multiple chiral centers, the flexibility of the structure, or lack of ultraviolet absorption, the stereoscopic configuration remained unresolved. The discovery of various sesquiterpenoids enriches the understanding of the chemical composition of the genus and species and provides references for further analysis of pharmacological substances of SP.

Objective:To investigate the efficacy of oblique lumbar interbody fusion (OLIF) combined with percutaneous transforaminal endoscopic decompression (PTED) and posterior pedicle fixation through Wiltse approach in the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis.Methods:From June 2017 to February 2022, 103 patients (50 males and 53 females) of lumbar spondylolisthesis accompanied with lumbar spinal stenosis were performed with OLIF combined with PTED and posterior pedicle fixation. The mean age was 64.1±5.2 years (range, 42-87 years). All involved cases were single-segment and included 83 cases of L 4, 5, 17 cases of L 3, 4, and 3 cases of L 2, 3. Among them, 94 cases were performed for the first time, and other 9 were revision surgery treated by posterior lumbar laminectomy previously. The visual analog scale (VAS) was used to evaluate the low back pain and leg pain, and the Oswestry disability index (ODI) was used to evaluate the lumbar function. The VAS and ODI scores were recorded respectively before the operation, at discharge, 1, 3, 6 months after the operation and at the last follow-up. Macnab criteria was used to evaluate the clinical efficacy at the last follow-up. At the same time, imaging measurements were conducted, including the anterior and posterior disc height, segmental lordotic angle, percentage of slip on lateral X-ray film and the vertebral canal area on axial MRI before and after surgery. Results:All of 103 patients were successfully operated in one stage with an average operation time of 177.7±21.5 min (range, 155-220 min), and an average intraoperative blood loss of 55.9±18.3 ml (range, 30-150 ml). The mean follow-up time were 15.1±2.6 months (range, 6-36 months). There were significant differences in both VAS scores of back and leg and ODI scores at each postoperative time point when compared with preoperative ( F=508.25, F=1524.82, F=1148.68, P<0.001). Macnab criteria of the last follow-up was evaluated as follow: excellent in 85 cases, good in 14, fair in 4, and the excellent and good rate was 96.1%. The radiographic results showed the mean immediate postoperative anterior disc height, posterior disc height, segmental lordotic angle, percentage of slip and axial area of the vertebral canal were 15.23±2.97 mm, 9.32±2.31 mm, 14.36°±4.18°, 3.89%±3.11%, 113.37±47.27 mm 2, and thus all of those increased significantly compared to the mean preoperative 11.93±3.17 mm, 7.21±2.03 mm, 6.15°±3.99°, 23.66%±7.79%, 57.63±28.91 mm 2, respectively ( t=7.84, t=7.07, t=14.91, t=27.62, t=9.68, P<0.001). All cases achieved bony fusion during 6-12 months after operation. The incidence of surgery-related complications was 10.7% (11/103). There were 3 cases of end plate fracture and 2 cases of dural injury, which had no complaint after operation. There was 1 case of pedicle screw entering into the spinal canal by mistake, and the symptoms of nerve damage appeared after operation. After 1 year it basically returned to normal. There were 2 cases of thigh numbness and 1 case of psoas major weakness after operation, all of which relieved after 4 weeks. There was 1 case continuous pain of abdominal incision after surgery. There was 1 case of cage subsidence at the last follow-up. Conclusion:OLIF combined with PTED and posterior pedicle fixation through Wiltse approach is a minimally invasive surgical method for the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis. With the combined minimally invasive techniques, the decompression, fusion and fixation of the lumbar spine can be fulfilled perfectly. It has the advantages of minimally invasive, good clical outcome, few complications and rapid rehabilitation.
