1.Interleukin-17 induces the production of inflammation and bone erosion related factors via signal transducer and activator of transcription 3 pathway in fibroblast-like synoviocytes of rheumatoid arthritis
Chinese Journal of Rheumatology 2017;21(5):338-341
Objective To study the regulatory effect of interleukin-17 on the production of inflammation and bone erosion related factors of fibroblast-like synoviocytes (FLSs) from rheumatoid arthritis (RA) patients and to investigate whether signal transducer and activator of transcription 3 (STAT3) is implicated in this regulatory effect.Methods FLSs were acquired through primary culture from RA patients.Receptor activator for nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) expression in FLSs were determined using western blot analysis.The level of IL-6,granulocyte-mac rop hage colony stimulating fac tor (GM-CSF)and IL-8 were determined by enzyme linked immunosorbent assay (ELISA) assay.Statistical product and service solutions (SPSS) 17.0 statistical software was used for single factor analysis of variance and LSD-t comparison between each two groups.Results IL-17 stimulated FLSs and promoted the release of IL-6,GM-CSF and IL-8 (t=2.135,P<0.01) and increased the production of RANKL (t=2.105,P<0.01) and reduced the production of OPG (t=2.502,P<0.01).However,targeted silencing of STAT3 could inhibit the effect of IL-17 on FLSs [control group:IL-6 (512±18) pg/ml;GM-CSF (591±25) pg/ml;IL-8 (473±10) pg/ml;RANKL (2.310±0.096);OPG (0.614±0.311);IL-17 group:IL-6 (1 630±39) pg/ml;GM-CSF (1 825±18) pg/ml;IL-8 (2 804±41) pg/ml;RANKL (4.010±0.256);OPG (0.131±0.101);STAT3 silent group:IL-6 (405±21) pg/ml;GM-CSF (451±12) pg/ml;IL-8 (370±9) pg/ml;RANKL (0.850±0.298);OPG (1.120±0.342)].Conclusion STAT3 pathway is critical to IL-17-induced regulatory effect on the release of inflammation and bone erosion related factors of FLSs.IL-17 can induce the inflammation and bone erosion of RA via STAT3.

Objective To investigate the subthreshold depression for long-term survivors after breast cancer surgery and its effect on their quality of life (QOL). Methods The self-made general questionnaire, Centre for Epidemiological Studies Depression Scale (CES- D), Hamihon Rating Scale for Depression and Functional Assessment of Cancer Therapy- Breast were used to investigate the subthreshold depression and its effect on their QOL for 210 long-term survivors after breast cancer surgery. The difference in general conditions and score of QOL between the subthreshold depression and non-subthreshold depression groups was also compared. Results The subthreshold depression with incidence rate of 46.67%(98/210) was observed for the log-term survivors after breast cancer surgery in this study. The results indicated that the age (≤50) (OR=5.627, 2.662,P<0.01), marriage (unmarried, divorced or widowed) (OR=5.087, P<0.01), employment (unemployed, sick leave or retired) (OR=2.077,P<0.05) and low income (<3000 RMB/month) (OR=3.375,P<0.01) were the key factors that led to the occurrence of subthreshold depression. The score of QOL for the subthreshold depression group were lower than those of the non-subthreshold depression group (t=-6.653--2.926,P<0.01), and had a significantly negative correlation with score of depression and QOL (β=-0.362--0.132). Conclusions A high incidence rate of subthreshold depression for long-term survivors after breast cancer surgery was observed. The incidence rate of subthreshold depression increased for the patients with younger age, low income,unmarried or unemployment. Due to their low QOL, attentions should be paid to the early detection and early prevention for the long-term survivors with subthreshold depression after breast cancer surgery.

Acute ischemic stroke has become one of the important causes of death and disability in human beings, especially in elderly patients. Intravenous thrombolysis with alteplase is an important treatment. However, there are many underlying diseases and poor overall conditions in elderly patients, which increase the risk of intracranial hemorrhage. Intracranial hemorrhage transformation makes the patient′s condition worse, which is the most serious complication of alteplase intravenous thrombolysis, and also one of the important reasons for the low treatment rate of alteplase intravenous thrombolysis in elderly patients. Therefore, we need to pay close attention to the occurrence mechanism and risk factors of intracranial hemorrhage transformation after alteplase intravenous thrombolysis in elderly patients, so as to reduce the risk of intracranial hemorrhage transformation, improve the prognosis and reduce the risk of morbidity and mortality.

Objective To investigate the influences of different factors on postpartum pelvic floor muscle injury, and provide clinical evidence to the early prevention of pelvic floor dysfunction (PFD). Methods A total of 65 630 women, who participated the postpartum pelvic floor function screening in Tianjin, from December 2011 to December 2014 were selected in this study. The uniform detect methods was used in this study. The analysis based on the PFD was diagnosed by physi?cians of Women’s and Children’s Health Center in each district. The influences of different factors on postpartum pelvic floor muscle were analyzed. Results There were 19 452 (29.6%) women suffering from postpartum pelvic floor muscle inju?ry, with the abnormal rate 29.6%, which was higher in rural areas than that in urban areas (33.9%vs 27.8%). The abnormal rate was higher in women with junior middle education or below (34.1%) than that in women with senior middle or polytech?nic schooling (30.4%), and women with college or higher education (27.7%). There was a higher abnormal rate in women with vaginal surgery delivery (40.8%) than that in women with natural delivery (32.5%) and women with caesarean section (27.2%). The muscle abnormal rate was higher in women having given two or more than two times of deliveries (34.6% , 31.5%) than those having initial delivery (29.1%). Multiple factor analyses showed that city residency, higher education and less delivery times were protecting factors for postpartum pelvic floor muscle while vaginal surgery was a risk factor for post?partum pelvic floor muscle. Conclusion There is a high incidence of postpartum pelvic floor muscle injury in the region of Tianjin. Analyzing the risk factors and strengthening the management of pelvic floor muscle injury by early prevention or ear?ly treatment would help to reduce the incidence of PFD effectively during pre-pregnancy and perinatal periods.
