Chronic migraine is a common episodic brain dysfunction disorder, which often progresses from migraine and is frequently accompanied by sleep disorders, anxiety, depression or obesity. Extensive connections exist between the hypothalamus and other components of the central nervous system; through integrating pain signals, neural conduction and inflammatory pathways, the hypothalamus becomes an important hub for migraine chronicization. This review, combined with clinical imaging evidence, analyzes the pathogenic mechanisms of chronic migraine and its complications from perspective of the hypothalamus as the higher neural center, so as to provide useful references for prevention and treatment of chronic migraine.

Objective:To explore the predictive value of pre-treatment platelet-to-albumin ratio (PAR) in short-term prognosis of endoscopic treatment for cirrhosis with esophageal and gastric variceal bleeding(EGVB).Methods:By retrospective analysis method, the clinical data of 195 cirrhotic patients with EVGB from January 2019 to April 2022 treatment at Bengbu First People′s Hospital were collected and analyzed. The PAR was calculated according to platelet count and albumin. The independent risk factors that affecting 6-week rebleeding and death were analyzed by univariate and multivariate Cox regression, the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of PAR for rebleeding and death, and Kaplan-Meier survival analysis was used to evaluate the rebleeding rate and survival rate of patients with different PAR ratios.Results:Among 195 patients, 36 patients were rebleeding and 159 patients were non-rebleeding within 6 weeks; while 15 cases died and 180 cases survived. The platelet count, PAR in the rebleeding group were lower than those in the non-rebleeding group, the direct bilirubin, triglyceride, alanine transaminase, prothrombin time and mortality in the rebleeding group were higher than those in the non-rebleeding group: 74.0(66.5, 88.8) × 10 9/L vs. 98.0(85.0, 111.0)×10 9/L, 2.48(2.18, 2.78) vs. 3.35(2.81, 4.04), 18.5(14.0, 23.8) μmol/L vs. 16.0(11.0, 20.0) μmol/L, (4.73 ± 2.52) mmol/L vs. (3.94 ± 1.65) mmol/L, 36.0(27.0, 46.0)U/L vs. 21.0(13.3, 33.0)U/L, (14.78 ± 1.63) s vs. (13.47 ± 0.87) s, 36.11%(13/36) vs. 1.26%(2/159), there were statistical differences ( P<0.05). Cox multivariate regression showed that PAR, alanine transaminase were the independent risk factors for the rebleeding ( P<0.05), PAR was the independent risk factor for the death within 6 weeks ( P<0.05). The area under the curve (AUC) of PAR for predicting 6-week rebleeding and death was 0.876, 0.776, the cut-off was 2.94, 2.71, the specificity was 69.8%, 72.2%, the sensitivity was 94.4%, 73.3%, respectively. According to the cut-off of PAR to predict rebleeding, the 6-week rebleeding rate in the PAR≤2.94 group was higher than that in the PAR>2.94 group ( χ2 = 36.88, P<0.01). According to the cut-off of PAR to predict death, the 6-week mortality rate in the PAR≤2.71 group was higher than in the PAR>2.71 group ( χ2 = 16.44, P<0.01). Conclusions:PAR can be used as a predictor for rebleeding and death within 6 weeks of EGVB in cirrhotic patients.

Objective:To explore the expression level and clinical significance of low-density granulocytes (LDGs) in peripheral blood of patients with inflammatory bowel disease (IBD) .Methods:A cross-sectional survey was conducted. Clinical data of IBD patients admitted to the Department of Gastroenterology, the First Affiliated Hospital of Anhui Medical University from August 2022 to January 2023 were collected. A total of 45 healthy people were enrolled as the normal control group. Simple endoscopic score for Crohn′s disease (SES-CD) was used to evaluate the activity of Crohn′s disease (CD) and Mayo endoscopic score (MES) was used to evaluate the activity of ulcerative colitis (UC). Laboratory indicators included LDGs, white blood cell count (WBC), hemoglobin (HB), platelet count (PLT), C-reactive protein (CRP), neutrophil to lymphocyte ratio (NLR), and fecal calprotectin (FC). The difference in LDGs level between IBD patients and the normal control group was statistically analyzed and the relationship between LDGs level and clinical characteristics of IBD patients was analyzed. Receiver operating characteristic (ROC) curve was used to calculate the predictive value of LDGs for the disease activity of IBD.Results:A total of 130 IBD patients were included, including 83 CD patients and 47 UC. Compared with the normal control group, the LDGs levels of patients in the CD group and UC group were respectively higher[CD: 0.53% (0.32%, 1.41%) vs. 0.19% (0.12%, 0.29%), H= 57.71, P<0.001; UC: 0.87% (0.43%, 1.90%) vs. 0.19% (0.12%, 0.29%), H= 73.23, P<0.001]. Compared with the CD patients in remission phase, the level of LDGs in active CD patients was higher ( P<0.001). Compared with the CD patients in mild activity phase, the LDGs levels of CD patients in moderate and severe activity phases were higher (all P<0.05). In terms of different disease behaviours, the level of LDGs in stricturing CD patients was the highest [1.37% (0.91%, 3.06%), all P<0.05]. Compared with the UC patients in remission phase, the level of LDGs in active UC patients was higher ( P<0.001). Compared with the UC patients in mild activity phase, the LDGs levels of UC patients in moderate and severe activity phases were higher (all P<0.05). In the CD group, LDGs level was positively correlated with CRP, FC, NLR, PLT, simple Crohn′s disease activity index (CDAI), and SES-CD ( r= 0.374, 0.548, 0.345, 0.284, 0.764, 0.721, all P<0.05). In the UC group, LDG levels was positively correlated with CRP, FC, NLR, Sutherland disease activity index (DAI), and MES ( r= 0.325, 0.666, 0.474, 0.638, 0.740, all P<0.05). In CD patients, the cut-off value of LDGs was 0.565%, with the area under curve (AUC) of 0.873, sensitivity of 73.50%, and specificity of 99.30%. In UC patients, the cut-off value of LDGs was 0.545%, with the AUC of 0.877, sensitivity of 76.90%, and specificity of 100.00%. Conclusion:The expression of LDGs in IBD patients is significantly high, which correlates with the disease activity and may be used as a biological marker for the clinical evaluation of IBD patients.

Objective: To evaluate the feasibility and efficacy of naked-eye assessment (NA) of ultrasound-guided fine needle aspiration cytology(US-FNAC) smears, which was performed by a trained non-cytological physician. Methods: A total of 290 smears of FNAC in 143 thyroid nodules were used to evaluate the value of NA by an assistant with more than two years experience of intervention with ultrasound guidance. NA results such as the background of smear (bloody/non-bloody), thickness (thick/thin), as well as the contents (granulated/non-granulated) were recorded. The correlation between NA and cytological results was analyzed. Number of cells under microscopy, the non-diagnostic rate, and the significance between benignity and malignancy with different features of specimens were compared. Results: There was no significant difference between the NA background and cytological findings(P=0.707, 0.200, 0.705, respectively). There was significance in number of cells, non-dianostic rate between thick and thinner specimens (P=0.000, 0.001, respectively). However, there was no significance in benignity and malignancy between thick and thinner specimens (P=0.385). There was significance in cytology results between the granulated and non-granulated smears(all P=0.000). The difference was found in 51.1% of the smears with granulates were malignancy in cytology. While 77.8% of the non-granulated smears were ultimately diagnosed as benignity. Conclusions The NA could be performed by a trained non-cytological physician and contribute to preliminary predictions of cytology effect.

Objective To establish a tree shrew model of Fusarium solani keractitis by injecting Fusarium solani conidia into the corneal stroma.Methods Fusarium solani was inoculated into Sabouraud culture medium and incubated at 26℃ for 7 days.Fungal suspension was collected and the number of spores was adjusted to 1 × 1010 CFU /mL on the blood cell count plate.Forty healthy tree shrews were randomly divided into experimental group (n=30) and control group (n=10).In the experimental group, 50 μL of fungal spore suspension was injected into the cornea center with a 29G needle, and 50 μL saline was injected in the control group.The models were evaluated by anterior segment photography, in vivo confocal microscopy, histopathology, and corneal tissue culture.Results The fungal infiltration, the degree of edema of corneal epithelial and endothelial cells, and the number of mycelium were positively correlated with time.The number of infiltrating inflammatory cells, mainly, neutrophils, reached a peak on the 7th day after modeling.The mycelial growth was parallel to the stromal fibers.After the successful establishment of the model, the corneal tissue culture showed the growth of Fusarium solani.The successful rate of modeling was 86%.Conclusions The tree shrew model of Fusarium solani keratitis is established by injecting spores of Fusarium solani into the cornea.

Objective To analyze and study the relationship between plasma adhesion molecules,free amino acids and ovarian cancer.Methods A total of 67 patients with ovarian cancer in our hospital during the time of March 2015 to May 2016 were selected as the observation group,and 67 healthy women at the same time were selected as the control group.The plasma adhesion molecules and free amino acids levels of two groups were detected and compared,The detection levels of observation group with different stages and degree of differentiation of ovarian cancers were compared.The relationship between plasma adhesion molecules,free amino acids and ovarian cancer were analyzed by the Logistic analysis.Results The plasma adhesion molecules levels of observation group were all higher than those of control group (P ＜ 0.05),the plasma free amino acids levels were all lower than those of control group (P ＜ 0.05),and the detection levels of observation group with different stages and degree of differentiation of ovarian cancer plasma adhesion molecules and free amino acid levels had significant differences (P ＜ 0.05).The Logistic analysis showed that the plasma adhesion molecules and free amino acids had close relationship to the ovarian cancer (all P ＜ 0.05).Conclusions The plasma adhesion molecules and free amino acids of the patients with ovarian cancer show abnormal expression state,and the expression levels of patients with different stages and degree of differentiation of ovarian cancer have certain differences,so the detection value of those indexes in the patients with ovarian cancer is higher.
