Objective:To investigate the effectiveness and safety of endovascular therapy for acute progressive stroke caused by large vessel occlusion (LVO).Methods:Patients with progressive stroke caused by LVO admitted to the Department of Neurology, Yueyang Central Hospital from January 2019 to February 2022 were retrospective included. Patients with an Alberta Stroke Program Early CT Score (ASPECTS) or posterior circulation ASPECTS (pc-ASPECTS) ≥6 after progression were selected for endovascular therapy, including mechanical thromboectomy, thrombus aspiration, balloon angioplasty, stenting, or a combination of the above methods. Patients in the time window (anterior circulation within 12 h and posterior circulation within 24 h) and outside the time window (anterior circulation >12 h, posterior circulation >24 h) as well as those in the anterior and posterior circulation were compared.Results:A total of 20 patients with progressive stroke caused by LVO received endovascular treatment were included. There were 17 males and 3 females, aged 59.45±12.06 years. Three patients (15%) developed asymptomatic intracranial hemorrhage, and 12 (60%) had a good outcome 3 months after procedure. There were no statistically significant differences in the rate of successful vascular recanalization, incidence of intracranial hemorrhage, and the rate of poor outcomes between patients within and outside the time window and between the patients with anterior and posterior circulation.Conclusion:Endovascular therapy may be safe and effective for patients with progressive stroke caused by LVO with ASPECTS or pc-ASPECTS scores ≥6.

Infertility is gradually becoming a major problem affecting health worldwide, and male factors also play an important role in infertility. Extracellular vesicles (EVs) are ultramicro membranous vesicles released by cells during activation or apoptosis, which play an important role in cell communication. Relevant studies have shown that extracellular vesicles contain a variety of bioactive substances and participate in infertility related pathophysiological processes by influencing the content of intercellular transmission. Therefore, we reviewed the relationship between extracellular vesicles and male infertility, and expounded the occurrence and potential treatment of male infertility from another perspective.

Objective:To summarize the clinical characteristics and treatment effect of patients with acute oral 84 disinfectant poisoning, so as to improve the understanding, diagnosis and treatment of the disease.Methods:In January 2022, 25 hospitalized patients with acute oral 84 disinfectant poisoning admitted to our department from March 2016 to August 2021 were selected as the research objects, and their general conditions, poisoning reasons, poisoning time, dose of poisoning, clinical manifestations, blood routine and biochemical indicators, diagnosis, treatment and prognosis were selected.Results:A retrospective analysis was performed. Among the 25 patients, there were 4 males and 21 females, aged from 20 to 91 years, and M ( Q1, Q3) was 38.7 (27, 46) years; The poisoning time (from exposure to poison to treatment) was 1~72 h, and M ( Q1, Q3) was 10.5 (3, 11.5) h. The length of stay was 1~20 days, and M ( Q1, Q3) was 5.72 (2, 7) days.The dose was 40-500 ml, and the M ( Q1, Q3) was 219.6 (100, 330) ml. Chest CT showed exudative changes in both lungs in 4 patients, excessive decreased permeability in 1 case and pleural effusion in 1 case. Gastroscope showed 2 cases of erosive inflammation of gastric body and antrum, 1 case of esophageal ulcer and cardiac ulcer, 1 case of corrosive gastritis, gastric fundus ulcer and esophageal stenosis. Abdominal X-ray showed 1 case of abdominal intestinal dilatation and pneumatosis with multiple gas-liquid planes.There were 1 case of type I respiratory failure, 6 cases of gastrointestinal bleeding and 1 case of incomplete intestinal obstruction. There were 19 cases of nausea and vomiting, 9 cases of abdominal pain, 6 cases of pharyngeal pain and 6 cases of retrosternal burning pain, 1 case of cough and 2 cases of fatigue.

OBJECTIVE: To explore the genetic basis for a case of Lamb-Shaffer syndrome. METHODS: Genomic DNA was extracted from peripheral blood samples and subjected to whole exome sequencing(WES). Suspected variant was verified by Sanger sequencing. RESULTS: The patients was found to harbor a heterozygous c.1495delA(p.Thr499Glnfs*5) frameshift variant of the SOX5 gene by WES. Sanger sequencing confirmed that the same variant was a de novo variant. Based on the American College of Medical Genetics and Genomics guidelines, c.1495delA(p.Thr499Glnfs*5) variant of the SOX5 gene was predicted to be pathogenic (PVS1+PS2+PM2). CONCLUSION The c.1495delA(p.Thr499Glnfs*5) variant of the SOX5 gene probably underlies the Lamb-Shaffer syndrome in this patient.

The elevated expression of the hyaluronan-mediated motility receptor (HMMR) is known to be highly associated with tumor progression in prostate cancer, but the molecular mechanisms underlying the regulation of HMMR expression remain unclear. Here, we report that mammalian target of rapamycin (mTOR) is a key regulator of HMMR expression, for which its kinase activity is required. Pharmacological inhibitors of mTOR, such as rapamycin and Torin2, markedly suppressed the mRNA level as well as the protein level of HMMR in LNCaP and PC-3 cells. Our data demonstrate that such regulation occurs at the transcription level.HMMR promoter reporter assays revealed that the transcription factor SRF is responsible for the mTOR-mediated transcriptional regulation of HMMR gene. Consistently, the suppression of HMMR expression by Torin2 was noticeably reversed by the overexpression of SRF. Moreover, our findings suggest that the SRF binding sites responsible for the transcriptional regulation of HMMR through the mTOR-SRF axis are located in HMMR promoter sequences carrying the first intron, downstream of the translational start site. Furthermore, the upregulation of HMMR by DHT was abolished by stimulation with rapamycin, prior to DHT treatment, suggesting that mTOR activity is required for the induction of HMMR expression by androgen. Collectively, our study provides new mechanistic insights into the role of mTOR/SRF/AR signaling in HMMR regulation in prostate cancer cells.

Objective:To analyze and summarize the basic characteristics and clinical features of botulism patients caused by cosmetic injection of botulinum toxin.Methods:Retrospective investigation and analysis method were used to analyze the data of botulism patients caused by cosmetic injection of botulinum toxin admitted to the Poisoning Treatment Center of the PLA from March 2016 to June 2019.Results:Total of 380 cases were included in this study, including 114 hospitalized cases and 266 emergency cases. The majority patients (97.4%) were female, and most of them (39.5%) were among 30-39 years old. Most of the cases occurred in beauty salons or beauty studios, and most of the botulinum toxin injected was fake and inferior products. Onset latency were mainly distributed in 3 to 6 days. Common clinical symptoms included dizziness, blurred vision, eyes open weakness, dysphagia, chest tightness of breath, fatigue, diplopia, nausea, bilateral eyelid drooping, and dysarthria. The "4D" sign of cranial nerve injury occurred less frequently, mainly with mild and moderate poisoning; The occurrence rates of dysarthria, dysphagia, eyes open weakness, blurred vision, choking in drinking water, chewing weakness, bilateral eyelid drooping, decreased limb muscle strength, and chest tightness of breath in the hospitalized case were significantly higher than those in the emergency cases (all P < 0.05). Three hundred and nine patients received botulinum antitoxin therapy. The dose of botulinum antitoxin was 20 000 (20 000-30 000) U, with a total treatment duration of 4 (3-7) days in the emergence cases, and 30 000 (30 000-50 000) U with a total treatment time of 8 (5-11) days in the hospitalized cases, and there were significant differences between the two groups ( P < 0.05). All cases were followed up with good prognosis. Conclusions:Cosmetic injection of botulinum toxin has certain risk. If symptoms of poisoning occur such as dizziness, blurred vision, eyes open weakness and dysphagia, patients should be treated promptly, and early treatment with botulinum antitoxin can improve the prognosis.

Objective: To explore an effective long non-coding RNA (lncRNA) signature in predicting the prognosis of hepatocellular carcinoma through the analysis on RNA sequencing data of hepatocellular carcinoma patients and peritumoral tissues in the Cancer Genome Atlas (TCGA) database. Methods: The clinical characteristics and RNA sequencing data of 377 hepatocellular carcinoma patients were obtained from TCGA database by the end of February 2018. Then, differentially expressed lncRNAs between 50 pairs of tumor and peritumoral tissues were explored using student’s t-test. Next, a lncRNA signature was established through LASSO Cox regression analysis. All the patients were divided into four groups (<P₂₅, P₂₅-, P₅₀-, ≥P₇₅) based on the cut-off quartiles signature. Finally, compared with the control group (<P₂₅), the hazard ratios (HRs) of three groups (P₂₅-, P₅₀-, ≥P₇₅) were calculated by using Cox regression. The survival outcomes of patients in the four groups were compared to evaluate the capacity of the lncRNA signature model. Results: A total of 951 differentially expressed lncRNAs were identified between tumor and peritumoral tissues. A three-lncRNA signature, including LNCSRLR, MKLN1-AS and ZFPM2-AS1, was established to predict the prognosis of hepatocellular carcinoma patients. The outcome suggested that the death risk of the ≥P₇₅ group was 1.57 times larger than that of the <P₂₅ group (95%CI: 1.06-2.31, P<0.05). Conclusion The three-lncRNA signature, which established by LNCSRLR, MKLN1-AS and ZFPM2-AS1, was significantly associated with the prognosis of hepatocellular carcinoma patients based on TCGA database data.
