Renal metastasis from differentiated thyroid cancer (DTC) is uncommon and is hard to be distinguished from primary renal cell carcinoma. There is no consensus on diagnosis and treatment, and decisions about surgery and 131I therapy doses usually depend on experience. To better understand clinical characteristics and current treatment status, this study systematically reviews existing studies, exploring epidemiological features, clinical symptoms, imaging findings (including lesions characteristics across various imaging modalities), therapeutic strategies, and prognosis of DTC renal metastases, providing evidence-based references for clinical practice.

Objective:To explore the association of cerebral venous outflow assessed by CT angiography (CTA) with first pass effect (FPE) in patients with acute anterior circulation large vessel occlusion accepted mechanical thrombectomy (MT).Methods:A retrospective analysis was performed; patients with acute anterior circulation large vessel occlusion accepted MT and CTA in Department of Neurology, Affiliated Hospital of Xuzhou Medical University from July 2018 to June 2021 were consecutively enrolled. Cerebral venous outflow in baseline CTA was evaluated using Cortical Vein Opacification Score (COVES). Patients were categorized into either FPE or non-FPE groups based on recanalization of occluded vessels after initial MT. General information, clinical features, radiological data, and surgery-related data between the 2 groups of patients were collected and compared. Significant variables ( P<0.1) from univariate analysis were included into a multivariable Logistic regression model to explore the relation between COVES and FPE. Predictive value of COVES in FPE was assessed using receiver operating characteristic (ROC) curve. Results:Out of the 143 patients enrolled in this study, 52 were into the FPE group and 91 were into the non-FPE group. Compared with the non-FPE group, the FPE group had higher COVES scores, higher proportion of patients with good cerebral venous drainage (COVES≥3), smaller core infarct volume, and shorter time from femoral artery puncture to vessel recanalization, with significant differences ( P<0.05). Multivariable Logistic regression analysis revealed that COVES was still corelated with FPE after adjusting covariates such as baseline NIHSS scores, core infarct volume, and time from femoral artery puncture to vessel recanalization ( OR=0.730, 95% CI: 0.567-0.940, P=0.015). ROC curve demonstrated that the combined model of COVES with aforementioned factors (COVES scores+baseline NIHSS scores+core infarct volume+time from femoral artery puncture to vessel recanalization) had an area under the curve of 0.757 (95% CI: 0.672-0.841, P<0.001), with sensitivity of 61.5% and specificity of 78.0%. Conclusion:Favorable cerebral venous drainage is an independent predictor for successful FPE in patients with acute anterior circulation large vessel occlusion accepted MT.

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.

Objective: To understand the epidemiological and spatial distribution characteristics of mushroom poisoning events in Zunyi, and to provide theoretical basis for the prevention of mushroom poisoning at the grassroots level. Methods: Descriptive analysis and spatial distribution of mushroom poisoning events reported by foodborne disease surveillance system in Zunyi were carried out. Results: A total of 525 cases of mushroom poisoning events were reported in Zunyi in the past ten years, with a total of 1 758 cases poisoning casesand 29 deaths. The occurrence of mushroom poisoning had seasonal fluctuation, mainly from June to October, accounting for 89.90% of the total. Family was the main place of mushroom poisoning, accounting for 96% of the total. Autochthonous gathering was the main source of mushroom poisoning events. Conclusion Mushroom poisoning is one of the main causes of food poisoning death. With the help of geographic information system(GIS), the distribution map of toadstools is preliminarily explored by combining environmental factors with the distribution of mushroom types.

Objective: To analyze the epidemiological characteristics of plant and mushroom poisoning events among people aged 0-19 in Guizhou Province from 2015 to 2019, so as to provide the basis for prevention and control of food poisoning events among children and adolescents. Methods: Data of people aged 0 to 19 involved in plant and mushroom poisoning incidents reported by the foodborne disease outbreak surveillance system in Guizhou Province from 2015 to 2019 were collected, verified, sorted and statistically analyzed. Results: From 2015 to 2019, there were 590 cases of plant and mushroom poisoning among people aged 0 to 19 in Guizhou Province, 1 441 people were poisoned and 5 died. In May and September, family and collective dining halls were the places with the highest incidence of plant and poisonous mushroom poisoning incidents, accounting for 90.68% (535/590) of the total incidents. Poisonous mushrooms and masanberry accounted for 71.69% (423/590) of the food poisoning causes, and 5 people died of poisoning were caused by poisonous mushrooms. Conclusion In the cases of plant and mushroom poisoning among people aged 0-19 years in Guizhou Province,preschool primary and middle school students in rural areas are most vulnerable population of poisoning, so it is necessary to strengthen the publicity and education on the prevention and control of toxic plant and mushroom poisoning among children and teenagers in rural areas, so as to reduce the occurrence of relevant poisoning incidents.

Objective　To investigate the predictive value of TOAST（Trial of Org 10172 in Acute Stroke Treatment） and lipoprotein-associated phospholipase A2（Lp-PLA2） for early recurrence of ischemic cerebrovascular disease after transient ischemic attack（TIA）and minor ischemic stroke of anterior circulation. Methods　A total of 190 patients with TIA and minor ischemic stroke of anterior circulation were selected and the general information and supplementary examinations were recorded. The patients were classified etiologically into large-artery atherosclerotic stroke（LAA） group and non-LAA group according to TOAST. According to the recurrence of ischemic cerebrovascular disease within 30 days，the patients were divided into positive event group and negative event group，and the differences between the two groups were compared. ROC curve was used to determine the best cutoff value of Lp-PLA2 for predicting positive event. Multivariate analysis was performed to identify potential predictors of recurrence. Finally，ROC curve was used to analyze the predictive value of Lp-PLA2 and LAA alone or in combination for recurrent ischemic cerebrovascular disease in the early stage of TIA and minor ischemic stroke of anterior circulation. Results　For positive event group，the age，proportion of TIA or cerebral infarction history，proportion of LAA and the level of Lp-PLA2 were higher than those of negative event group（P<0.05）.The best cutoff value of Lp-PLA2 was 304.50 ng/ml（sensitivity and specificity were 0.645 and 0.711 respectively）. LAA and Lp-PLA2 ≥ 304.50 ng/ml were independent risk factors for recurrent ischemic cerebrovascular disease within 30 days after TIA and minor ischemic stroke of anterior circulation. The area under ROC curve of LAA，Lp-PLA2≥ 304.50 ng/ml and combination of both were 0.671，0.678 and 0.729 respectively. The area under ROC curve of combined prediction of LAA and Lp-PLA2 was the largest. Conclusion　LAA combined with Lp-PLA2≥304.50 ng/ml could predict the risk of early recurrence of ischemic cerebrovascular disease in TIA and minor ischemic stroke of anterior circulation.

Purpose: Seroma formation is a common complication in breast cancer patients undergoing mastectomy, and it negatively affects patient recovery after surgery. The present study aimed to evaluate a simple method using fascia suture technique to fix the flap and reduce the incidence of seroma. Methods: A single-center, prospective, randomized controlled trial was carried out among 160 patients who had undergone mastectomy from May 2018 to September 2019. All patients were randomly divided into the fascia suture group (n = 80) or control group (n = 80) and were followed up for at least 3 months for the assessment of immediate and late complications after surgery. Results: No significant differences were observed between the 2 groups with regard to the basic characteristics. Duration of surgery in the fascia suture group was longer by about 6 minutes compared with that in the control group (114.93 ± 13.67 minutes vs. 108.81 ± 15.20 minutes, p = 0.008). The fascia suture group had a shorter duration of drain placement (10.99 ± 3.26 days vs. 13.85 ± 5.37 days, p < 0.001), a smaller volume of the total drainage (460.95 ± 242.92 mL vs. 574.83 ± 285.23 mL, p = 0.007), and the first 3-day drainage (224.96 ± 101.01 mL vs. 272.3 ± 115.47 mL, p = 0.006), compared with the control group. The incidence of seroma formation (G2 or G3) was significantly lower in the fascia suture group compared with the control group (28.8% vs. 12.5%, p = 0.033). Besides, there was no statistical difference between the 2 groups in the assessment of other complications, including postoperative pain, hematoma, surgical site infections, flap necrosis, and skin dimpling (all p > 0.050). Conclusion The fascia suture technique is a simple and effective method for reducing seroma formation and should be used to prevent seroma formation after mastectomy.

The aim of this study was to provide a summary estimate of depression prevalence among people with ankylosing spondylitis (AS) in comparison to those without AS. A systematic literature search was conducted using PubMed, Embase, PsycINFO, Web of Science, the Cochrane database library, China National Knowledge Infrastructure, and Wanfang Database from their inception to December 2016. The results showed that thirty-one eligible studies involving 8,106 patients were analyzed. Fifteen methods of defining depression were reported. The overall pooled prevalence of depression was 35% (95% CI, 28–43%), with high between-study heterogeneity (I²=98.8%, p<0.001). The relative risk of depression among people with AS was 1.76 (95% CI: 1.21–2.55, eight studies, n=3,006) compared with people without AS. The depression score [standardized mean difference (SMD)=0.43, 95% CI: 0.19–0.67, seven studies, n=549] was higher in AS patients than in controls. The main influence on depression prevalence was the sample size and country of origin. In conclusion, one-third of people with AS experience symptoms of depression. Depression was more prevalent in AS patients than in controls. Further research is needed to identify effective strategies for preventing and treating depression among AS patients.
