This review highlights the currently understood mechanism and regulation of miR-198 in different diseases, and its possible diagnostic and therapeutic potential.Tumor-associated macrophages (TAMs), which could be classified into the classical (M1-like) and alternatively activated (M2-like) phenotype, were considered to be important tumor-promoting components in lung cancer microenvironment. Several studies reported that TAMs in lung tumor islet or stroma are usually correlated with poor prognosis. Further studies showed that TAMs could promote the initiation of tumor cells, inhibit antitumor immune responses, and stimulate tumor angiogenesis and subsequently tumor metastasis of lung carcinoma. Currently, TAMs have been considered as penitential targets of lung cancer. This review summarizes from the fundamental information of TAMs to the its role in metastasis and present evidence for TAMs as a potential target of cancer therapy.Differentiating small cell neuroendocrine (NE) carcinoma (SCNC) of the prostate from adenocarcinoma with NE differentiation based on morphological features alone sometimes can be challenging. Given that treatment strategies vary depending on histological type, an accurate diagnosis is critical. This study aimed to identify the accurate diagnostic factors for SCNC of the prostate. Furthermore, the possibility of novel treatment strategies through genetic analysis was also investigated. Prostate biopsies conducted in our hospital between January 2017 and May 2020 were included. Consequently, seven cases of SCNC and four cases of adenocarcinoma with NE differentiation were identified. No significant differences in the serum neuron-specific enolase, pro-gastrin-releasing peptide, and prostate-specific antigen (PSA) levels were observed between both tumors. The Ki-67 labeling index was significantly higher, and PSA immunoreactivity tended to be lower in SCNC. Although the morphology was undetectable, genetic analysis confirmed several mutations, including those of PIK3CA and TP53. The fact that morphological findings are not apparent indicates that genetic investigation rather than only morphological findings would be important in the future. In conclusion, given the heterogeneity of serum NE markers in SCNC, diagnosis based on these markers alone is challenging. A high Ki-67 labeling index and low PSA immunoreactivity may be useful for diagnosis, but p53 immunoreactivity is insufficient in distinguishing. Although further studies are required to interpret the results of the genetic analysis involving ALK, PIK3CA, and TP53 mutations, the results of our genetic analysis suggest that PIK3CA mutations in SCNC of the prostate may provide a novel therapeutic strategy.Breast cancer (BC) is the most prevalent cancer in females and the second reason of cancer-related mortality in females in the world. It is thought to be a complex interaction of variables like personal lifestyle, climate, genetics, and reproductive factors. Many polymorphisms have been linked to cancer in genome-wide association experiments, and they are linked to long non-coding RNAs (lncRNAs). LncRNAs, which have > 200 nucleotides in their transcripts, affect many biological processes, including differentiation, migration, apoptosis, cell cycle, and cell proliferation. Different lncRNAs with tumor suppressor and oncogenic roles have been shown to have elevated expression levels in the development of BC. Single-nucleotide polymorphisms (SNPs) in lncRNAs can affect the expression level, structure, and function of lncRNAs. LncRNA polymorphisms are predictive of cancer incidence, making them useful for early detection and customized therapy control. SNPs may affect genetic susceptibility to BC. This study was set to see whether there was a link between lncRNA polymorphisms and the risk of BC. Accordingly, the individual and combined genotypes of lncRNA-related variants could predict BC and clinical and care outcomes. However, further large-scale trials of diverse ethnic groups and comprehensive health records should be performed to validate the results. Furthermore, adequate functional assessments should be carried out to shed light on the etiology of BC. DATA AVAILABILITY Not applicable.

We retrospectively analyzed a cohort of patients treated at our Centre with bone marrow concentrated (BMC) injection for aneurysmal bone cyst (ABC) of the spine, in order to propose this treatment as a valid alternative for the management of ABCs.

Fourteen patients (6 male, 8 female) were treated between June 2014 to December 2019 with BMC injection for ABC of the spine. The mean age was 15.5 years. The mean follow up was 37.4 months (range 12-60 months). The dimension of the cyst and the degree of ossification were measured by Computed Tomography (CT) scans before the treatment and during follow-up visits.

Six patients received a single dose of BMC, five patients received two doses and in three patients three doses of BMC were administered. The mean ossification of the cyst (expressed in Hounsfield units) increased statistically from 43.48±2.36 HU to 161.71±23.48 HU during follow-up time and the ossification was associated to an improvement of the clinical outcomes. The mean ossification over time was patients treated with multiple injections. No significant difference in ossification was found between cervical and non-cervical localization of the cyst. Moreover, the initial size of the cyst was not statistically associated with the degree of ossification during follow-up CONCLUSIONS Results of this paper reinforce our previous evidence on the use of BMC as a valid alternative for spinal ABC management when SAE treatment is contraindicated or ineffective.Sepsis often leads to multiple organ failure or even death and is a significant health problem that contributes to a heavy economic burden. The lung is the first organ to be affected by sepsis. Presently, there is no specific drug or method to treat sepsis and sepsis-induced acute lung injury (ALI). H2S, along with CO and NO, is a physiological gas that acts as a signaling molecule and plays an active role in fighting various lung infections. GYY4137 is a novel H2S donor that is stable in vivo and in vitro. However, particularly in the context of ferroptosis, GYY4137 affects cecal ligation and puncture (CLP)-induced ALI by a mechanism that is not understood. Ferroptosis is a new form of cell necrosis. The primary mechanism is the accumulation of cellular lipid ROS in an iron-dependent manner. The principal objective of this project was to investigate the effects of GYY4137 on ferroptosis and autophagy in a mouse model of sepsis-induced ALI. We divided the experimental mice randomly into 5 groups (1) sham grous inhibited by treatment with GYY4137, indicating that GYY4137 could inhibit the activation of autophagy in sepsis-induced ALI by blocking mTOR signaling.

Most research on mucosal contact headache has focused on mucosal contact between the nasal septum and middle or inferior turbinate. However, rarely have any studies explored how headache is related to the only one contact point between superior turbinate and nasal septum.

To explore how headache is related to the only one contact point between superior turbinate and nasal septum.

80 patients with headache were selected. The mucosal contact between superior turbinate and nasal septum was removed to study the relationship between the contact point and headache, with a follow-up of 12months.

Headache symptoms in 56 cases disappeared entirely. Significant relief was observed in 20 patients, and unsatisfactory results in only 4 patients, with the success rate being 95%.

Some patients with headaches who had intranasal mucosal contact areas benefitted from the surgery. Satisfactory results were achieved by endonasal surgery in 95% of our patients in whom intranasal contact points were believed to be the cause of their headaches who had a mucosal contact point between the superior turbinate and the septum.

We explored the outcomes and voice parameters of patients undergoing plasma radiofrequency (RF) ablation to treat intubation granulomas.

Prospective case series.

Patients with intubation granulomas who met the inclusion criteria underwent RF ablation. The complete remission rate and voice function were evaluated preoperatively and at 6months postoperatively.

We enrolled 13 patients with 25 intubation granulomas. The mean time between intubation and initial diagnosis was 38.6days and that between intubation and surgical diagnosis was 2.7months. All 25 granulomas were successfully removed and histologically confirmed. No surgical remnant was evident on the vocal folds and complete glottal closure was observed at 2weeks postoperatively. No recurrence or RF ablation-related complications were observed during the 6-month follow-up. The complete remission rate was 100% (13/13). In addition, the mean hoarseness, roughness, breathiness, asthenia, and strain (GRBAS) scores, and the maximum phonation time (MPT), improved significantly after treatment (all P<0.05).

RF ablation is effective and safe for patients with intubation granulomas who failed medical management or request the procedure. In this study, the complete resolution rate was high and voice restoration outcomes were good.

Inner ear hemorrhage (IEH) is a rare cause of sudden sensorineural hearing loss (SSNHL). This study aimed to evaluate the lesional patterns in patients with presumed IEH from morphological and functional aspects.

Seventeen patients with SSNHL and presumed IEH who completed audio-vestibular tests were included. The main outcome measures included clinical characteristics, radiology, and functional test results.

The morphological findings and functional tests revealed differences in locations and lesional spectrums. The magnetic resonance imaging (MRI) hyperintensity was likely to involve the vestibule (88.2%), the cochlea (76.5%), and the posterior and lateral semicircular canals (76.5% and 70.6%, respectively). Furthermore, 70.6% of cases showed abnormality in the entire labyrinth, and abnormalities in the vestibule/semicircular canals were observed in 17.6% of cases. Meanwhile, dysfunction was sequentially detected in the cochlea (100%), semicircular canals (94.1%), and vestibule (70.6%); 64.7% of cases showed combined deficit in the entire labyrinth, and 29.4% of cases showed combined deficit in the cochlea/semicircular canals. Although lesions in the labyrinth were frequently detected, the results of the radiological and functional tests did not always match and significantly differed in either cochlear or superior semicircular canal damage detection (p<0.05 each).

In this cohort, IEH preferentially caused sudden audio-vestibular impairment, which was well demonstrated by a combination of MRI and functional tests. The specific lesional configurations revealed in this study may suggest a possible pathomechanism that could be further explored as a therapeutic target.
