Idiopathic intracranial hypertension (IIH) is a clinical syndrome manifested as headache,transient visual disturbance,and pulsatile tinnitus,characterized by increased intracranial pressure,and involved Departments of Neurology,Neurosurgery,Ophthalmology,Otorhinolaryngology and other disciplines.Due to increase of obese people,incidence of IIH is still increasing.With the development and application of imaging,ocular coherence tomography and transanal ultrasound detection technology,the application of stenting for purpose of protecting vision has increased,people's understanding of IIH has been improved and diagnostic criteria have been revised,and acetazolamide has been clarified as the first-line treatment,but its exact mechanism remains to be confirmed by further studies.This article is now summarized as follows for IIH,in order to allow clinicians to raise awareness of the disease.

OBJECTIVE To investigate the expression of serum miR-222-3p in papillary thyroid carcinoma and its clinical significance.METHODS Total RNA in serum was extracted from 121 patients of papillary thyroid carcinoma and benign thyroid diseases.The reverse transcription quantitative real-time polymerase chain reaction(qRT-PCR) method was used to detect the expression of miR-222-3p,and then the potential correlation between serum miR-222-3p and clinical pathological characteristics of papillary thyroid carcinoma was analyzed.The receiver operating characteristic area under the curve(ROCAUC) and their index for diagnosis evaluation were also calculated.RESULTS The median expression level of serum miR-222-3p in papillary thyroid carcinoma patients was significantly higher than that of control group (2.2188 vs 0.7022,P=0.002).Although the expressions of serum miR-222-3p was not associated with the gender,age,capsule invasion,TNM stage,but it was positively correlated with tumor size,bilateral involvement,lesion quantity and lymph node status.ROC curve analysis showed that the specificity and sensitivity of the miR-222-3p diagnosis of papillary thyroid cancer were 79.75％ and 61.90％,respectively,while the ROC-AUC was 0.717.CONCLUSION The serum miR-222-3p is over expressed in papillary thyroid carcinoma and its expression is significantly correlated with tumor progression.It will be helpful for PTC diagnosis.

Objective:To investigate the clinical significance of Delphian lymph node (DLN) dissection in papillary thyroid cancer (PTC) .Methods:The correlation of DLN detection and metastasis in 208 PTC patients with various clinical and pathological features was analyzed retrospectively. The value of DLN metastasis in predicting PTC high-risk features was evaluated, and the tendency of surgical selection for PTC with DLN metastasis was also discussed.Results:① Of 208 PTC patients, DLN was detected in 144 patients (69.23%) . The detection rate of DLN was related to gender, number of central lymph nodes (excluding DLN) removed and metastasis (all P<0.05) . Male, greater number of nodes in the central compartment (excluding DLN) was more favorable for DLN detection. ② The rate of DLN metastasis was 18.27% (38/208) . In the univariate analysis, DLN metastasis was significantly associated with the following variables:gender, whether it is microcarcinoma, isthmus involvement, number of lesions, extrathyroidal extension, tumor size, number of central lymph nodes (excluding DLN) removed and metastasis (all P<0.05) . In the multivariate analysis, tumor size larger than 1 cm, isthmus involvement and greater number of central lymph nodes (excluding DLN) metastasis were independent risk factors of DLN metastasis ( P<0.05) . ③ The sensitivity of DLN metastasis to predict extranodal invasion, central and lateral lymph node metastasis was 54.54%, 37.36% and 62.86%, with specificity of 78.69%, 92.45% and 55.56%, respectively. ④ Patients with DLN metastasis were more likely to receive total thyroidectomy, bilateral central lymph node dissection, and lateral cervical lymph node dissection. Conclusions:Due to high rate of DLN detected and metastasis, DLN should be routinely dissected. Patients with DLN metastasis predict high risk characteristics of PTC and extensive lymph node metastasis, which is of clinical significance for lymph node dissection.

Objective: To explore the correlation between obesity and the risk of colorectal adenoma, so as to provide theoretic evidence for the intervention of the high-risk population for colorectal cancer. Methods: Based on the Screen Project of Early Diagnosis and Treatment of Colorectal Cancer in Jiashan County, from August 2012 to March 2018, the results of colonoscopy and body measurement information of the high-risk population for colorectal cancer were collected. According to the results of colonoscopy, 3 895 patients with colorectal adenoma and 11 232 healthy controls were enrolled. Multivariate logistic regression was used to analyze the correlation between overweight (body mass index (BMI) 24.0 to 27.9 kg/m²), obesity (BMI≥28.0 kg/m²) and the risk of colorectal adenoma. Results: After adjusting for gender and age, compared with that of individuals with normal weight (BMI 18.5 to 23.9 kg/m²), the risk of colorectal adenoma of obese patients increased by 36% (odds ratio (OR)=1.36, 95% confidence interval (CI) 1.18 to 1.56). After stratifing by gender, compared with that of individuals with normal weight, the risk of colorectal adenoma of obese males increased by 30% (OR=1.30, 95%CI 1.07 to 1.59), the risk of colorectal adenoma of overweight females and obese females increased by 15% (OR=1.15, 95%CI 1.01 to 1.31) and 40% (OR=1.40, 95%CI 1.14 to 1.71), respectively. After stratifing by age, compared with that of individuals with normal weight, the risk of colorectal adenoma of obese patients aged between 40 and 59 years increased by 31% (OR=1.31, 95%CI 1.07 to 1.61), and the risk of colorectal adenoma of overweight and obese patients aged between 60 and 74 years increased by 13% (OR=1.13, 95%CI 1.01 to 1.27) and 39% (OR=1.39, 95%CI 1.15 to 1.70), respectively. The results of subgroup analysis according to pathological types indicated that the risk of non-advanced adenoma and advanced adenoma of obese patients increased by 35% (OR=1.35, 95%CI 1.16 to 1.57) and 39% (OR=1.39, 95%CI 1.06 to 1.83), respectively. Conclusions Obesity is correlated with colorectal adenoma, which is more significant in women, individuals aged between 60 and 74 years and advanced adenoma. The intervention of high-risk population for colorectal cancer should include body mass control.
