Interleukin 33 (IL 33),one member of the IL-1 family,is expressed in many types' tissue and regulation of multiple target cells via its suppression of tumorigenicity 2 (ST2) receptor.Therefore,the crucial roles of the novel cytokine IL-33 in allergic,endocrine diseases,infectious diseases and cancer are becoming characterized.The function of IL-33 in different parasite infection is distinctive in parasitic infections,due to the difference in pathogenic mechanism and in the time course of IL-33 expression.

Objective To investigate the related factors on effects of uterine artery embolization (UAE) in the treatment of dysmenorrhea in patients with adenomyosis, and to construct and validate the efficacy prediction model. Methods A total of 127 cases of adenomyosis patients with symptoms of dysmenorrhea in Guangzhou No.1 People′s Hospital and Nanfang Hospital of Southern Medical University from June 1999 to December 2009 were reviewed. The evaluation standard was to improve the degree of dysmenorrhea, the related factors of efficacy were analysed. Combined with artificial neural network theory, the effect prediction model was constructed, and the effectiveness of the model was evaluated using receiver operating characteristic (ROC) curve, and the effectiveness of the cut-off point was calculated. The model was validated by 68 cases of patients with adenomyosis in the Nanfang Hospital from January 2010 to November 2014. Results (1) In 127 cases of dysmenorrhea patients, UAE treatment was effective in 98 cases, effective rate was 77.2% (98/127). (2) Age was an independent predictor of effective UAE treatment (HR=1.129, P=0.026);in the range of this study, the greater the age, the higher the UAE treatment efficiency. (3) The developing situation of ovary branches of uterine artery was an independent predictor of effective UAE treatment (HR=0.460, P=0.020), the efficiency of patients whose intraoperative bilateral uterine artery ovarian branch did not develop was 89.7%(35/39), the efficiency of patients whose unilateral uterine artery ovarian branch was developing was 84.1% (37/44) and the efficiency of patients whose bilateral uterine artery ovarian branch were developing was 59.1% (26/44). (4) Blood supply of adenomyosisis was an independent predictor of effective UAE treatment (HR=0.313, P=0.001). Type Ⅰ (bilateral predominated) patients, efficiency was 93.5%(43/46);typeⅡ(bilateral balanced) patients, efficiency was 78.0%(39/50);type Ⅲ (unilateral predominated) patients, efficiency was 51.6% (16/31). (5) UAE for the treatment of adenomyosis efficacy of artificial neural network prediction model was constructed, the model′s area under the ROC curve was 0.808, the optimal cut-off point was 0.669 13. Actual verification of the model, sensitivity was 96.5%, specificity was 81.8%, positive predictive value was 96.5%and negative predictive value was 81.8%, the total accuracy was 94.1%. Conclusions (1) Age, the developing situation of ovary branches and blood supply of adenomyosis are the independent predictors of effective UAE treatment. (2) The artificial neural network prediction model is satisfied with the accuracy and the accuracy of prediction.

Objective: Diabetic retinopathy (DR) is the retinal consequence of chronic progressive diabetic microvascular leakage and occlusion. Non-proliferating diabetic retinopathy (NPDR) is the early stage of DR. It eventually occurs to some degree in all patients with diabetes mellitus. In recent years, many clinical trials have shown that Compound Danshen Dripping Pill (CDDP) may be associated with the improvement of NPDR symptoms. The aim of this study was to quantitatively summarize the association between CDDP and the therapeutic effects of NPDR. Methods: It was conducted that a systematic literature search of PubMed, Web of Science, CNKI, VIP and Wanfang Data updated in June 2020 with the following search terms: “diabetic retinopathy” or “retinopathy” or “DR” or “NPDR”, in combination with “Compound Danshen Dripping Pill” or “Salvia miltiorrhiza” or “Danshen”. Risk ratio (RR) and weighted mean difference (WMD) with their 95% confidence interval (CI) was calculated between treatment and control groups. The sensitivity analyses were undertaken by removing each individual study when high heterogeneity appeared. Subgroup analysis, Meta-regression, and publication bias analysis were also conducted. The strength of evidence was evaluated with the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) method. Results: Twenty-six RCTs involving 2047 subjects were included to conduct a Meta-analysis after screening the studies, extracting the data, and assessing the study quality. The Stata15.0 software was utilized for processing. Meta-analysis indicated that curative effects of treatment group with CDDP was significantly better than control [RR = 0.54, 95% CI (0.40, 0.73); moderate-quality evidence]. In addition, the results showed that CDDP was significantly associated with improving retinal hemorrhages [WMD = −0.62, 95% CI (−0.78, −0.46); low-quality evidence], the vision [WMD = 0.14, and 95% CI (0.09, 0.19), low-quality evidence], fundus fluorescence angiography [RR = 0.37 and 95% CI (0.23, 0.60); low-quality evidence], reduction of retinal microaneurysm [WMD = −3.74 and 95% CI (−4.38, −3.11); moderate-quality evidence], hemangioma volume [WMD = −3.15, 95%CI (−3.45, −2.85); moderate-quality evidence], macular thickness [WMD = −5.52, 95%CI = (−64.27, −48.78); low-quality evidence], mean defect [WMD = −1.65 and 95% CI (−1.95, −1.34); very low-quality evidence], fasting blooding glucose [WMD = −0.95, 95% CI (−1.19, −0.70); low-quality evidence), hemoglobin A1c [WMD = −0.62, 95% CI (−0.93, −0.30); low-quality evidence], high sensitive C reaction protein [WMD = −5.66, 95% CI (−8.01, −3.31); low-quality evidence]. Sensitivity, subgroup, and Meta-regression analyses were also assessed. Conclusion: The study demonstrated that CDDP has beneficial clinical effects for treating NPDR and improve the vision. Moreover, it indicated that oral CDDP in NPDR patients led to significant regulation of serum level of fasting blooding glucose, hemoglobin A1c and high sensitive C reaction protein, which was associated with the pathogenesis of NPDR. However, high-quality and large randomized clinical trials will be needed to prove the consequence in future.
