Objective: To analyze the phenotypic-genotypic characteristics of hereditary deafness caused by OTOA gene variations. Methods: Family histories, clinical phenotypes and gene variations of six pedigrees were analyzed, which were diagnosed with hearing loss caused by OTOA gene variations at the PLA General Hospital from September 2015 to January 2022. The sequence variations were verified by Sanger sequencing and the copy number variations were validated by multiplex ligation-dependent probe amplification (MLPA) in the family members. Results: The hearing loss phenotype caused by OTOA variations ranged from mild to moderate in the low frequencies, and from moderate to severe in the high frequencies in the probands, which came from six sporadic pedigrees, among which a proband was diagnosed as congenital deafness and five were diagnosed as postlingual deafness. One proband carried homozygous variations and five probands carried compound heterozygous variations in OTOA gene. Nine pathogenic variations (six copy number variations, two deletion variations and one missense variation) and two variations with uncertain significance in OTOA were identified in total, including six copy number variations and five single nucleotide variants, and three of the five single nucleotide variants were firstly reported [c.1265G>T(p.Gly422Val),c.1534delG(p.Ala513Leufs*11) and c.3292C>T(p.Gln1098fs*)]. Conclusions: OTOA gene variations can lead to autosomal recessive nonsyndromic hearing loss. In this study, the hearing loss caused by OTOA defects mostly presents as bilateral, symmetrical, and postlingual, and that of a few presents as congenital. The pathogenic variations of OTOA gene are mainly copy number variations followed by deletion variations and missense variations.

Anterior cervical fusion surgery is the first choice for spine surgeons in the treatment of cervical spine diseases. It has significant effects in treating cervical degenerative diseases, trauma and tumors and other cervical diseases. In anterior cervical fusion, it is necessary to use a distractor to properly distract the intervertebral space, so as to fully expose and relieve the compressive factors, restore the physiological height, curvature and stability of the lesion segment, and achieve the best surgical effect. However, there is currently no consensus on the standard distraction height for the intervertebral space during anterior cervical surgery. This article reviewsed the progress of intervertebral space height in anterior cervical fusion from three dimensions:the relationship between intervertebral space height and cervical disc degeneration mechanism, the selection of intervertebral space height during operation, the recovery of intervertebral space height and the postoperative effect, so as to provide theoretical basis and reference for spinal surgeons when performing intervertebral distraction during operation.

Abstract: The loop-mediated isothermal amplification (LAMP) technique is a technique for the specific and efficient amplification of target fragments at a constant temperature using two pairs of specially designed primers and a strand displacement activity DNA polymerase. LAMP technique is a simple, rapid, specific, sensitive and cost-effective nucleic acid amplification method, and therefore has a promising future in the field rapid detection of Mycobacterium tuberculosis and grassroots applications. In this review, the basic principles and characteristics of the LAMP technique, the main molecular markers for the diagnosis of tuberculosis, and the use of different molecular markers and various types of novel techniques in the diagnosis of pulmonary tuberculosis, extrapulmonary tuberculosis, and drug-resistant tuberculosis were described. The LAMP technique has been widely used in the diagnosis of tuberculosis with high sensitivity and specificity, but the technique still has some shortcomings. This paper reviews the progress of its application in tuberculosis in recent years and provides an outlook on its development, with a view to providing a rational research direction for rapid diagnosis of tuberculosis in a resource-limited environment.

OBJECTIVE Only limited number of drugs are currently available for treating ischemic stroke. Therapeu?tic angiogenesis has recently emerged as one of the most promising therapies for cerebral ischemic injury. Isopropyl-β-(3,4-dihydroxyphenyl)-α-hydroxypropanoate (IDHP) is a metabolite derived from the botanical formulation for Dantonic?. Here, we investigated the angiogenic efficacy of IDHP in cerebral ischemia. METHODS The in vivo effects of IDHP were evaluated in the C57BL/6 mouse Matrigel plug and rat transient middle cerebral artery occlusion (tMCAO) models. Primary human umbilical vein endothelial cells (HUVEC) and human brain microvascular endothelial cells (HBMEC) were used to explore the effects of IDHP on stimulating proliferation, migration and tube formation in vitro. ELISA and Western blotting were used to quantitate the release and expression of relevant target molecules and signaling path?ways. RESULTS IDHP reduced infarct volume and improved sensorimotor function in rats subjected to tMCAO by pro?moting angiogenesis, and promoted Matrigel neovascularization in mice. Moreover, IDHP produced a biphasic modula?tion on proliferation and migration both in HUVEC and HBMEC. It also induced tube formation in a 12-day HUVEC-HDF co-culture model and in Matrigel assays. IDHP-induced angiogenesis was accompanied by increased levels of p-AMPKα (Thr172) and p-eNOS (Ser1177) both in vitro and in vivo, and the decreased level of VEGF in rat brains on day 1 whereas enhanced level of VEGF on day 3 and 7 after tMCAO. Mechanistically, AMPK knockdown or pharmacologi?cally inhibiting AMPK and its upstream kinases (CaMKKβ) inhibited the eNOS phosphorylation induced by IDHP in HUVEC. Furthermore, selective eNOS inhibitor (L-NIO), selective CaMKKβ inhibitor (STO) and AMPKa inhibitor (Com?pound C) blocked the capillary-like tube formation in the co-culture model induced by IDHP (10 nmol · L-1). CONCLU?SION Collectively, these findings showed that IDHP protected rats from cerebral ischemia-reperfusion injury by promot?ing angiogenesis via activating CaMKKβ/AMPK(Thr172)/eNOS(Ser1177) signaling, and suggest it to be a promising new drug candidate for the prevention and/or treatment of cerebral ischemia and other vascular occlusive diseases.

The incidence rate of lung cancer is one of the highest incidence of malignancies in China. The gold standard for diagnosis requires pathological examination or cytological examination of biopsy. The invasive and sensitive nature of the two limits their use. Sputum contains a large number of nucleic acids and proteins, which is a good reflection of lung function. Lung cancer tissue will also affect the biological components in sputum. The detection of bioactive substances in sputum can contribute to the diagnosis of lung cancer. Based on the current research results at home and abroad, this paper reviews the bioactive substances in sputum that can be used for the diagnosis of lung cancer.
