Objective To screen for nonresponding cases of superficial transitional cell carcinoma of the bladder at an early stage of intravesical bacillus Calmette Guetin(BCG) therapy. Methods IL 8 and urine pH were assayed both before intravesical BCG instillation and after the 1st and 6th instillation for 32 cases of superficial transitional cell bladder cancinoma following TURB or partial cystectomy.Urinary IL 8 was measumed by chemiluminescence enzyme immunomeric assay and urine pH by routine examination.The result was studied with reference to the clinical outcome of the patients. Results All the patients have been followed up for 6～25 months with tumor recurrence in 5.Urinary IL 8 in these 5 dropped to 161.3?64.5 ng/L after the 1st instillation whereas it was 579.4?77.8 ng/L in the others ( P

Objective To investigate whether IL-17 could stimulate the vascular endothelial growth factor (VEGF) production on HaCaT cells alone. We also investigated whether shikonin could inhibited the proinflamation effects of interleukin-17(IL-17) acting on HaCaT cells. MethodsWe examined the expression of VEGF by double antibody sandwich enzyme-linked immunosorbent assay ( ELISA ) and realtime polymerase chain reaction(RT-PCR) in HaCaT cells and the cell supernatant. The viability of HaCaT cells in the drug group was detected by the Cell Counting Kit-8 (CCK-8). ResultsThe expression of VEGF in different time IL-17-stimulated groups on HaCaT cells and the cell supernatant were higher than the control group( P＜0.001 ). The expression of VEGF in different drug treatment groups on HaCaT cells and the cell supematant were lower than the stimulated group by IL-17 ( P＜0. 001 ). The cell viability of different drug treatment groups have no significant difference( P＞0.05 ). ConclusionWe show that IL-17 specifically and time-dependently augmented and induced VEGF expression on HaCaT cells and the cell supernatantThen shikonin markedly inhibited the increase tengency of IL-17 effection on HaCaT cells and the cell supematant level.

Objective:To explore the expression level of serum interleukin-17 (IL-17) in the patients with psoriasis vulgaris and the changes of interleukin-6 (IL-6) and interleukin-23 (IL-23) levels secrered by the HaCaT cells after stimulated with IL-17,and to clarify its clinical significance and the intervention effect of shikonin.Methods:Twenty-five normal controls,29 patients with psoriasis vulgaris and different groups of HaCaT cells (blank control group,IL-17-24 h group,IL-17-36 h group,IL-17-48 h group,shikonin+-IL-17 group,CsA+-IL-17 group and IL-17 group) were used as the subjects.The levels of serum IL-17 in the patients with psoriasis vulgaris and the levels of IL-6 and IL-23 in supernatant of HaCaT cells in various groups were measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction RT-PCR was used to detect the expression levels of IL-6 and IL-23 p19 mRNA in HaCaT cells in various groups.At the same time,Cell Counting Kit-8 (CCK-8) method was used to detect the viabilities of HaCaT cells in various groups.Results:The level of serum IL-17 of the patients in psoriasis vulgaris group was increased compared with nomral control group,especially in the severe skin lesion group (P＜0.05).The levels of IL-6 and IL-23 in HaCaT cells and supernatant and their mRNA expression levels in IL-17-24 h,IL-17-36 h and IL-17-48 h groups were significantly higher than those in blank control group (P＜0.01).The expression levels of IL-6 and IL-23 in HaCaT cells and supernatant and their mRNA expression levels in shikonin+IL-17 and CsA+IL-17 groups were lower than those in IL-17 groups (P＜0.05).No statistical differences were found in the cell viabilities between each drug treatment group and blank control group (P＞0.05).Conclusion:The expression level of IL-17 in the patients with psoriasis vulgaris is significantly increased,especially in the patients with severe psoriasis vulgaris.IL-17 can promote the secretion of IL-6 and IL-23 in HaCaT cells in a time-dependent manner.Shikonin can inhibit the proinflammatory effect of IL-17.

Objective To analyze the magnetic resonance imaging (MRI) of the spinal cord and clinical characteristics in patients with autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy.Methods A total of 1 040 samples of cerebrospinal fluid (CSF) and sera collected in the Second Affiliated Hospital of Guangzhou Medical University from March 2013 to June 2018 were tested with tissue-and cell-based assays,and 42 patients were found positive for GFAP-IgG.The clinical data and MRI characteristics of the spinal cord of 19 patients who were positive for GFAP-IgG in CSF with autoimmune GFAP astrocytopathy and lesions in the spinal cord were retrospectively reviewed.Results There were 12 females and seven males among the 19 patients,with onset age of (44±17) years.The main manifestations of these patients included limb weakness (14/19),abnormal vision (5/19),headache (4/19),seizure (4/19),dementia (3/19),etc.On MRI of the spinal cord,five patients showed involvement in the cervical cord alone,eight showed involvement in the thoracic cord alone and six had both cervical and thoracic segment involvement.Fifteen patients had longitudinally extensive myelitic abnormalities (≥3 vertebral segments long).Seven enhancement patterns were encountered.Lesions were displayed in the spinal cord and brain in eight patients.Central gray matter involvement in the spinal cord was found in all the 19 patients.Conclusions Autoimmune GFAP astrocytopathy more frequently presents in females than in males.MRI of the spinal cord has complex presentations and longitudinally extensive myelitic abnormalities usually.Patients often show central gray matter involvement in the spinal cord.Myelitic abnormalities present more often in thoracic segment than in cervical segment.Abnormalities in lumbar segment are less encountered.

Objective:To conduct a scope review on the application of ICU diaries in critically ill patients, laying the foundation for further exploration and construction of ICU diary patterns and frameworks that were in line with the national conditions and tailored to different regions and cultural backgrounds.Methods:The Joanna Briggs Institute Reviewer′s Manual was used as the methodological framework, and a computer search was conducted in nine domestic and international databases, including China National Knowledge Infrastructure, Wanfang Database, China Biomedical Literature Database, Cochrane Library, PubMed, and Embase, etc. The search period was from the inception of the databases until March 13, 2023. The included literature was screened, summarized, and analyzed.Results:A total of 19 articles were included. ICU diaries were commonly recorded using a combination of text and visuals, with the involvement of both healthcare professionals and family members. Most patients received ICU diaries approximately one month after their transfer from the ICU. Out of the 15 studies, ICU diaries were found to be effective, while 4 studies indicated no significant improvement in patients′ psychological issues. However, ICU diaries were still considered acceptable by patients and their families.Conclusions:The application of ICU diaries has shown positive significance in critically ill patients, but further research and exploration are needed to investigate its impact on issues such as post-traumatic stress disorder, anxiety, depression, and quality of life. In the future, a combination of multiple forms and high-quality research designs with large samples, long periods, and structured approaches should be employed to explore its application effects and long-term outcomes on psychological problems.

Objective Our study aimed to delineate the clinical and radiological features of patients with anti-myelin oligodendrocyte glycoprotein antibody (MOG-Ab)positive neuromyelitis optica spectrum disorder (NMOSD). Methods Fifty-seven patients with NMOSD and 29 patients with multiple sclerosis (MS) were collected. Data on clinical and radiological features of MOG-Ab positive patients with were analyzed retrospectively. Results MOG-Abs were present in 9/57 (15.8%) NMOSD patients and 2/29 (6.9%) MS patients. Both MOG and aquaporin-4 (AQP4) antibodies were positive in one case of NMOSD. There was no significant difference between the two groups (P＞0.05). There were more females than males having MOG-Ab positive NMOSD (females: males=7:1) and the average onset age was 41.4 ± 11.5 years. There was no significant difference in gender and age between MOG-Ab negative and AQP4-Ab positive groups(P＞0.05). The durations of disease were significantly shorter in either MOG-Ab positive NMOSD patients or MOG-Ab negative NMOSD patients than in AQP4-Ab positive group (P<0.05). Recurrence was the main disease pattern of all three groups and the frequency of recurrence was not significant different among three groups (P＞0.05). The incidence of optic neuritis was 62.5% in NMOSD patients with MOG-Ab positive and 43.5% in AQP4-Ab positive NMOSD patients (P＞0.05). There was no significant difference in the morphology and location of brain lesions among the three groups (P＞0.05). MOG-Ab positive NMOSD patients had long segment spinal cord lesions. The median length of the spinal cord lesions in the MOG-Ab positive group was similar to the other two groups (P＞0.05). Conclusions MOG-Ab positive NMOSD patients have higher proportion of females with shorter recurrence course, more likely complicated with optic neuritis. And the radiological features of brain and spinal cord were not specific to patients with AQP4-Ab positive.
