ObjectiveThe expression and significance of interleukin(IL)-17 in a murine model of experimental systemic sclerosis(SSc) was studied and its correlation with transforming growth factor-beta 1 (TGF-β1) was explored.Methods Thirty female BALB/c mice were randomly divided into 3 groups,including a control group, bleomycin(BLM) injection for 4 weeks group(model 1 group) and a termination injection of BLM 4 weeks group(model 2 group).The pathological changes of skin and lung were detected.The mRNA expressions of IL-17A,RORγt,TGF-β1 mRNA were evaluated by real-time PCR.Enzyme linked immunosorbent assay was used to measure the levels of IL-17 and TGF-β1 in the serum and bronchoalveolar lavage fluid(BALF).Comparisons among groups were performed by variance analysis.ResultsSkin and lung of the model groups showed evident inflammatory cell infiltration and increased deposition of collagen fibers.The score of dermal inflammation and lung fibrosis was significantly higher in the model 1 and model 2 groups (2.5±0.8,3.0±1.8), (2.4±0.8,3.1±1.2) as compared to that of the control group (0.9±0.7,0.9±1.0),(F=12.19,8.367,25.11,4.641; all P＜0.05).The amount of hydroxyproline was markedly increased in the model groups than in the control group.Compared with those of the control group,the mRNA levels of IL-17A,RORγt,TGF- 31 in the skin and lung of the model 1 group were higher.The levels of IL-17 in serum and BALF of the model 1 group was significantly increased and the levels of TGF- β1 were increased in BALF and decreased in the serum (all P＜0.05).The mRNA levels of IL-17A in skin and lung had a positive correlation with the mRNA levels of TGF- β1,score of dermal inflammation and lung fibrosis.The levels of IL-17 in serum had a positive correlation with hydroxyproline of the skin and lung.ConclusionIL-17 may participate in systemic immune-mediated inflammation and changes of skin and lung in SSc and when combined with TGF-β1 togetter will cause damage to skin and lung in SSc.

Background and purpose:Primary malignant melanomas of the uterine cervix and vagina are rare neoplasms with very poor prognosis. This article aimed at investigating the clinicopathologic characteristics, treatment and prognosis of primary malignant melanomas of the cervix and vagina. Methods:The clinical data of 51 patients with primary malignant melanomas of the cervix and vagina treated at Fudan University Shanghai Cancer Center from Dec.1998 to Jul. 2011 were reviewed. Results:The 2-and 4-year progression-free survival (PFS) rates were 32.8%and 13.1%, respectively. The 2-and 4-year overall survival (OS) rates were 67.2%and 39.8%, respectively. Three patients survived more than 5 years. Twenty-nine (56.9%) patients had a recurrence. The common sites were vaginal stump/pelvis (10 patients, 34.5%), liver (4 patients, 13.9%), lung (3 patients, 10.3%), bone (3 patients, 10.3%) and vulva (3 patients, 10.3%). Larger tumor size and lymphovascular space invasion were the independent predictors of poor OS (P<0.05). Pelvic lymph nodes metastases were associated with shorter PFS (P=0.05). Among them, those who received combined immunotherapy and chemoradiotherapy achieved longer median time to progression (TTP) (17 months) compared with patients who had chemotherapy alone (9 months) or immunotherapy alone (11 months). Conclusion:Primary melanomas of cervix and vagina have a very poor prognosis. The multidisciplinary treatment of combining surgery, chemoradiotherapy, and immunotherapy can improve the patients’ prognosis.

Objective To describe the effects of allergic and nonallergic rhinitis on patients with bronchial inflammation by comparing the bronchial inflammation characteristics . Methods All patients enrolled in the study were categorized into two groups according to rhinitis diagnostic criteria , 377 cases in the allergic rhinitis ( AR) group, 262 cases in non-allergic rhinitis ( NAR) group and another 264 patients without rhinitis as control group .Induced sputum differential cytology tests , exhaled nitric oxide concentration measurements and methacholine bronchial provocation tests were performed .The characteristics and differences in lower airway inflam-mation among the three groups were compared . Results The exhaled nitric oxide level and the positive rate of the exhaled nitric ox-ide were different significantly in AR group and NAR group than the control group (P<0.05);Bronchial provocation positive rate was 12.20%in AR group, and 6.10%in the NAR group, the difference was significant (P<0.05), and the levels in the two groups were significantly higher than the control group (P<0.05).AR group and NAR group has a significant different (P<0.05) propor-tions of eosinophil in induced sputum , while the positive rate of eosinophil in induced sputum was not different significantly ( P >0.05). Conclusion Bronchial inflammation may be aggravated by AR and NAR , so all patients with AR and NAR need treatment , and the degree of inflammation was higher in AR patients than the NAR patients .

ObjectiveTo investigate the clinical characteristics,epidemiology of patients with severe fever with thrombocytopenia syndrome bunyavirus (SFTSV) infection and genetic sequences of SFTSV.MethodsClinical data of five cases of severe fever with thrombocytopenia syndrome (SFTS)from Zhoushan Hospital during May 2011 to July 2011 were retrospectively analyzed.SFTSV gene was amplified by polymerase chain reaction (PCR).CD3+ CD4+ and CD3+ CD8+T lymphocytes were detected by flow cytometry (FCM).The sequences of isolated SFTSV strains were compared with those in GenBank. ResultsThe symptoms of continuous high fever,sore muscles,enlarged superficial lymph nodes,abdominal pain,diarrhea with gastrointestinal hemorrhage were observed.The white blood cells,platelets and CD3+ CD4+ T lymphocytes were progressive decreased in acute phase with the minimum of (0.97-2.00) × 109/L,(12-42) × 109/L and 7.52％-20.39％,respectively.The SFTSV was isolated from the sera of two patients.The sequences were compared with SFTSV sequences in GenBank.The homology of RNA-dependent RNA polymerase gene was 96％ compared with BX-2010,L-WWG,LN3,JS4,SD4,HN6 and AH12; the glycoprotein gene was 94％ ; N protein gene was 95％ compared with JS4,SD4 and LN4.The homology of the above three genes between two isolates was 99％.ConclusionsOur results suggest that SFTSV is sporadic in Zhejiang Province which is probably from native epidemic focus.SFTS is progressive and severe with acute onset.Multiple organ dysfunction is common in severe eases.

OBJECTIVE: To compare the symptoms and lower airway inflammatory factors of patients with allergic rhinitis (AR), and to observe the effect of nasal irrigation in the treatment of allergic rhinitis. METHOD: Sixty-one cases diagnosed as AR after skin prick test (SPT)were selected and randomly divided into three groups: 17 patients in group A used nasal steroid spray; 21 cases in group B used nasal irrigation; 23 patients in group C combined ir rigation with nasal steroid. Before and after 3 months treatment, nasal visual analogue scale (VAS) score, rhino conjunctivtis quality of life questionnaire (RQLQ) score, fractional exhaled nitric oxide (FENO) values were observed and compared in each group. RESULT: Before treatment, there is no statistically difference between three groups (P > 0.05). After 3 months of treatment, VAS, RQLQ, FENO of all patients was significantly decreased (P < 0.05); VAS, RQLQ score was not significantly different among the three groups (P > 0.05), FENO value has no statistically significant difference between group A and group B (P > 0.05), but were less than that in group C (P < 0.05). CONCLUSION Nasal irrigation can ameliorate nasal symptoms, improve quality of life, decrease lower airway inflammation of allergic rhinitis patients. Nasal irrigation is an effective treatment of allergic rhinitis. Nasal irrigation combined with nasal steroid can achieve more significant efficacy.

Objective:To explore the expression of long-chain noncoding RNA (lncRNA) and myocardial infarction-associated transcription (MIAT) in Leukocyte differentiation antigen (CD)4+T cells in peripheral blood of gastric cancer patients and its value of clinical application.Methods:Peripheral blood CD4+T cells were collected from 124 patients with gastric cancer, 90 benign gastric diseases patients and 80 healthy controls enrolled in Taizhou People′s Hospital from January 2019 to April 2021. The expression levels of MIAT and N6-methyladenosine(m6A) binding to MIAT promoter in CD4+T cells were detected by real-time fluorescent quantitative polymerase chain reaction (qPCR) and Chromatin immunoprecipitation (ChIP)-qPCR, respectively. Spearman test was used to analyze the correlation between MIAT and clinicopathological features, as well as between MIAT and regulatory T cell levels. The receivor operating characteristic curve (ROC) of the subjects was used to evaluate the MIAT expression level in the auxiliary diagnostic value of gastric cancer.Results:The relative expression levels of MIAT in the gastric cancer patients, the benign gastric diseases patients, and the healthy controls were 2.849 (2.131, 4.062), 1.511 (0.916, 1.855) and 0.963 (0.729, 1.432), respectively. The difference among the three groups was statistically significant ( H=158.25, P<0.001). The relative expression level of MIAT in the gastric cancer patients was significantly higher than the levels in the benign gastric diseases patients and healthy controls. The difference was statistically significant ( Z=100.63, 145.14, P<0.001). The binding activity of m6A to MIAT promoter in patients with early stage (stage Ⅰ and Ⅱ) and end stage (stage Ⅲ and Ⅳ) gastric cancer was 8.590±1.483 and 4.274±0.425, respectively. The difference was statistically significant ( t=6.255, P=0.002). Furthermore, the binding activity of m6A to MIAT promoter in the gastric cancer patients was significantly lower than that in patients with benign gastric diseases (17.267±3.106) and healthy controls (27.637±3.945) ( t=-7.331,-12.832, P<0.001). The relative expression of MIAT in CD4+T cells in peripheral blood of the gastric cancer patients had no significant difference in age(χ2=0.000, P=1.000), gender(χ2=0.000, P=1.000), CEA (χ2=0.648, P=0.421) and CA199(χ2=1.554, P=0.213), but had significant difference with tumor size expression(χ2=9.443, P<0.01), TNM stage(χ2=23.571, P=0.002) and lymph node metastasis (χ2=45.248, P<0.01). In addition, there was a significant positive correlation between the relative expression of MIAT in CD4+T cells and Treg level ( r2=0.76, P<0.001). The diagnostic efficacies of MIAT in CD4+T cells, CEA and CA199 in the gastric cancer patients were analyzed by ROC curve. When compared with patients with benign gastric diseases, the areas under the curve were 0.879, 0.635 and 0.611, respectively. When compared with healthy patients, the areas under the curve were 0.953, 0.784 and 0.598, respectively. Conclusions:The level of MIAT in CD4+T cells in peripheral blood of patients with gastric cancer is significantly higher than the levels in patients with benign gastric diseases and the healthy controls, which may be related with the decreased activity of m6A binding to the promoter of MIAT. The level of MIAT in CD4+T cells may be a relevant biomarker for the diagnosis and prognosis of gastric cancer.
