Background:
and Purpose Patients presenting with clinical characteristics that are strongly suggestive of neuromyelitis optica spectrum disorders (NMOSD) have a high risk of developing definite NMOSD in the future. Little is known about the clinical course, treatment, and prognosis of these patients with likely NMOSD at disease onset.
Methods:
This study prospectively recruited and visited 24 patients with the limited form of NMOSD (LF-NMOSD) at disease onset from November 2012 to June 2021. Their demographics, clinical course, longitudinal aquaporin-4 immunoglobulin G (AQP4-IgG) serology, MRI, therapeutic management, and outcome data were collected and analyzed.
Results:
The onset age of the cohort was 38.1±12.0 years (mean±standard deviation). The median disease duration was 73.5 months (interquartile range=44.3–117.0 months), and the follow-up period was 54.2±23.8 months. At the end of the last visit, the final diagnosis was categorized into AQP4-IgG-seronegative NMOSD (n=16, 66.7%), AQP4-IgG-seropositive NMOSD (n=7, 29.2%), or multiple sclerosis (n=1, 4.2%). Seven of the 24 patients (29.2%) experienced conversion to AQP4-IgG seropositivity, and the interval from onset to this serological conversion was 37.9±21.9 months. Isolated/mixed area postrema syndrome (APS) was the predominant onset phenotype (37.5%). The patients with isolated/mixed APS onset showed a predilection for conversion to AQP4-IgG seropositivity. All patients experienced a multiphasic disease course, with immunosuppressive therapy reducing the incidence rates of clinical relapse and residual functional disability.
Conclusions
Definite NMOSD may be preceded by LF-NMOSD, particularly isolated/ mixed APS. Intensive long-term follow-up and attack-prevention immunotherapeutic management is recommended in patients with LF-NMOSD.

Objective:To investigate the expression of forkhead box protein O3(FOXO3) in pancreatic cancer and its effect on the motility and proliferation of pancreatic cancer cells.Methods:The FOXO3 expression in pancreatic cancer and adjacent tissues was retrieved from LinkedOmics database. Western blotting and real-time quantitative polymerase chain reaction were used to detect FOXO3 expression in pancreatic cancer cells and human pancreatic stellate cells. PANC-1 and MIAPaCa-2 pancreatic cancer cells with low FOXO3 expression were selected to transfect FOXO3 overexpression plasmid and negative control plasmid, respectively. The motility and proliferation ability of pancreatic cancer cells were detected by colony formation assay, cell scratch assay, Transwell assay and flow cytometry.Results:In the LinkedOmics database, the relative expression of FOXO3 protein in the cancer tissues of 64 patients with pancreatic cancer was significantly lower than that in the adjacent tissues ( t=8.36, P<0.001). The number of clones in PANC-1 cell line was (30.0±6.6) after overexpressed FOXO3, which was lower than that in negative control cells (92.7±6.7), and the difference was statistically significant ( t=11.54, P<0.001). After overexpressed FOXO3 in PANC-1 and MIAPaCa-2 cell lines, the scratch repair rate was significantly decreased compared with the control group. In Transwell experiment, the number of cells in FOXO3 overexpressed group in PANC-1 cell lines was (21.0±6.6), which was lower than that of negative control groups (55.7±8.5), and the difference was statistically significant ( t=5.59, P=0.005). The results of MIAPaCa-2 cell line were consistent with that of PANC-1 cell line. After overexpressing of FOXO3 in PANC-1 and MIAPaCa-2 cell lines, the proportion of cells in the G0/G1 phase decreased, while the proportion in the S phase increased. Conclusion:The expression of FOXO3 was decreased in pancreatic cancer. Overexpression of FOXO3 could significantly inhibit the proliferation, migration and invasion of pancreatic cancer cells and induce cell cycle arrest, which is a potential target for the treatment of pancreatic cancer.

In order to improve the clinical attention to the poisoning of chlorfenapyr, the diagnosis and treatment strategy of chlorfenapyr poisoning were discussed. This paper collected 4 cases of chlorfenapyr in the emergency department of the Second Hospital of Hebei Medical University and 4 cases of literature review, summarized the clinical characteristics of pesticide poisoning cases containing chlorfenapyr in China, and summarized and analyzed the clinical data of the cases. Seven of the 8 patients died from poisoning by chlorfenapyr. Exposure to chlorfenapyr through respiratory tract and digestive tract showed high mortality. Fever, hyperhidrosis, elevated muscle enzymes and progressive central nerve damage were its prominent clinical characteristics. Most of the initial symptoms of exposure were not serious. Some patients, especially those with low exposure dose, had a relatively stable stage with or without clinical diagnosis and treatment. In case of sweating, obvious fever and disturbance of consciousness, the condition would deteriorate rapidly, respiratory and circulatory failure and eventually die. With the increase of production capacity and market launch, people have more opportunities to be exposed to chlorfenapyr. It is urgent to strengthen the basic and clinical research of chlorfenapyr poisoning; Attention should be paid to the observation and treatment in the initial stable stage of poisoning, which can be used as a reference for the treatment of oxidative phosphoric acid dissolving coupling agent (sodium pentachlorophenol) poisoning.

Objective:To investigate the expression of IKBKE and NF-κB in pancreatic cancer, and to explore the effect of IKBKE on pancreatic cancer proliferation and migration.Methods:Immunohistochemistry staining was used to study the expression of IKBKE and NF-κB in tissues of 61 pancreatic cancer patients admitted to the Second Hospital of Tianjin Medical University from January 2012 to January 2017 and 13 normal pancreatic tissues. The correlations between those expression to clinicopathological features were analyzed. Lentivirus mediated RNAi was transfected into pancreatic cancer cells to block IKBKE. Western blot was performed to test the silencing effeciency; CCK-8 and plate clone and scratch assays were used to investigate the proliferation and migration of pancreatic cancer.Results:Immunohistochemical staining showed that 60 (98.4%) of IKBKE staining were weakly positive, positive, and strongly positive in pancreatic cancer tissues, which were significantly higher than normal pancreatic tissues(76.9% cases were weakly positive and the rest were negative), and the differences were statistically significant ( P<0.05). All cases of NF-κB exhibited weakly positive expression and above in pancreatic cancer tissues, which was markedly higher than normal tissues (30.8% cases were weak positive and the rest were negative staining), statistically significant ( P<0.05). Survival analysis showed that patients with high level of IKBKE showed a shorter overall survival ( P<0.05). CCK-8, plate cloning and scratch assays showed that the proliferation and migration of were significantly decreased in IKBKE knocking down group ( P<0.05). Conclusions:IKBKE and NF-κB are highly expressed in pancreatic cancer, and IKBKE is correlated with NF-κB in pancreatic cancer. Blocking of IKBKE could distinctly inhibit the proliferation and migration of pancreatic cancer.
