Objective:To systematically evaluate the diagnostic value of fine-needle aspiration washout fluid for measuring thyroglobulin (FNA-Tg) and fine-needle aspiration cytology (FNAC) in cervical lymph node metastasis of papillary thyroid carcinoma.Methods:Chinese Journal Full-Text Database, Wanfang Database, VIP Chinese Science and Technology Journal Database and other databases from January 2016 to December 2020 were retrieved. And then diagnostic trials from the databases regarding the comparison of FNA-Tg and FNAC in the diagnosis of papillary thyroid carcinoma with neck lymph node metastasis based on the histopathological diagnosis as the gold standard were included. The literatures were screened out according to the diagnostic test inclusion criteria recommended by the Cochrane Collaboration Screening and Diagnostic Test Methods Group; and then the quality of the included literatures was evaluated and feature information was extracted. Review Manager 5.0 and MetaDiSc software were used to conduct Meta analysis, and a summary receiver operating characteristic (SROC) curve of FNAC and FNA-Tg in the diagnosis of lymph node metastasis was drawn to calculate the area under the curve and to judge the diagnostic efficacy.Results:A total of 19 articles and 2 792 cervical lymph nodes were finally included. The sensitivity of FNAC and FNA-Tg in the diagnosis of cervical lymph node metastasis in papillary thyroid carcinoma was 0.80 (95% CI 0.78-0.81) and 0.92 (95% CI 0.91-0.93), respectively; the specificity was 0.93 (95% CI 0.92-0.95) and 0.91(95% CI 0.89-0.93); the diagnostic odds ratio was 51.55 (95% CI 38.61-68.81) and 110.03 (95% CI 82.18-147.32), respectively; the areas under the SROC curve was 0.900 and 0.968, respectively. Conclusions:The accuracy of FNA-Tg in the diagnosis of cervical lymph node metastasis of papillary thyroid carcinoma is higher than that of FNAC. FNA-Tg can be used as an important diagnosis supplement to FNAC and it can be widely used in clinical practice.

Objective:To analyze the functional connectivity (FC) characteristics of sensory motor network (SMN) in patients with bipolar disorder type Ⅰ (BD-Ⅰ) by independent component analysis (ICA), and explore the correlation between abnormal SMN and clinical symptoms.Methods:Eighteen patients with BD-Ⅰ (BD-Ⅰ group) and 20 matched normal controls (HC group) were included.Both groups received resting state fMRI (rs-fMRI) scanning.Based on ICA-fMRI data, one-sample t-test and two-sample t-test were used to analyze the components of SMN and to explore abnormal brain regions between the two groups.Functional network analysis (FNC) was also used to explore the functional connectivity between SMN and other brain networks.Pearson correlation analysis were conducted by SPSS 17.0 to measure the potential associations between intra-and inter-network functional connectivity and age, education, score of Bech-Rafaelsen mania rating scale (BRMS), score of positive and negative syndrome scale (PANSS) and other indicators. Results:In BD-Ⅰ group, the functional connection in the right paracentral lobule (MIN: x=8, y=-32, z=68, t=4.86, P<0.001) and the right postcentral gyrus (MIN: x=41, y=-26, z=53, t=3.33, P<0.001) in SMN were higher than those in HC group.Compared with HC group, the connectivity value in patients with BD-Ⅰ increased between SMN-DAN (0.247±0.073, -0.078±0.080, t=-2.974, P<0.01, FDR adjusted), while the connectivity value decreased between SMN-DMN(-0.037±0.054, 0.272±0.067, t=3.520, P<0.01, FDR adjusted) and between SMN-rFPN(-0.034±0.055, 0.231±0.070, t=2.939, P<0.01, FDR adjusted). Conclusion:The sensorimotor network of patients with BD-Ⅰ has abnormal functional connections within and between networks, and FC values in some networks are positively correlated with manic symptoms, which may be part of the neural mechanisms of patients with BD-Ⅰ.

Inflammatory bowel disease (IBD) is a chronic intestinal inflammatory disease, and its treatment includes traditional medicines and biological agents. Therapeutic drug monitoring is an important tool to optimize the treatment of biological agents. Therapeutic drug monitoring of tumor necrosis factor inhibitors has been used to guide the clinical decision ⁃ making. However, the value of therapeutic drug monitoring of novel biological agents (vedolizumab and ustekinumab) in IBD remains unclear. This article summarized the pharmacokinetics, drug concentration and treatment outcome, optimization of the novel biological agents in the treatment of IBD.

To investigate the neuroprotective effect and possible mechanism of masitinib on cerebral ischemia-reperfusion injury in rats, healthy adult male Sprague-Dawley rats were divided into sham group (n = 12), model group (n = 12), masitinib low dosage group (n = 12), masitinib middle dosage group (n = 12), and masitinib high dosage group (n = 12). All rats was subjected to middle cerebral artery occlusion (MCAO) for two hours and reperfusion except sham group, and received treatment twice per day for 7 days once reperfusion started.Neurological score, infarct volume, and brain water content were detected; some autophagic markers, apoptotic and inflammatory cytokines were evaluated by Western blot and PCR after 7 d of reperfusion. Treatment with masitinib significantly ameliorated neurologic deficit, infarct volume and brain water after I/R injury. Masitinib also decreased the ratio of LC3II/I and the expression of Beclin-1 and increased the expression of p62 in the brain tissues of rats with I/R injury.Furthermore, it could inhibit apoptosis-related proteins and NF-κB expression. Masitinib could relieve the cerebral ischemia-reperfusion injury in rats through inhibiting autophagy and apoptosis.

This paper introduced a liver normothermic machine perfusion repair and assessment system. This system consists of a liver normothermic machine perfusion device, a fluorescence imaging system and a tissue oxygen detector. The normothermic machine perfusion device can continuously perfuse the donor liver and monitor and control the perfusion parameters in real time. The fluorescence imaging system can detect the indocyanine green metabolized by the liver to evaluate the microcirculation and the metabolism function of hepatocytes. The tissue oxygen detector can monitor the change of oxygen partial pressure of liver tissue in real time to evaluate the state of cell oxygen consumption.

Objective:To explore the diagnostic value of the combined detection of galactomannan (Gm) in bronchoalveolar lavage fluid (BALF) and IgG of aspergillus fumigatus in blood for pulmonary aspergillosis.Methods:Seventy-four patients with pulmonary aspergillosis admitted to Haiyan People′s Hospital from February 2017 to September 2019 were divided into chronic pulmonary aspergillosis group (35 cases) and invasive pulmonary aspergillosis group (39 cases). The BALF of ttwo groups were collected, the Gm level of BALF was tested, and the IgG level of blood aspergillus fumigatus was detected by using the aspergillus IgG enzyme-linked immunosorbent assay (ELISA) kit, and the positive prediction rate, negative prediction rate, diagnostic sensitivity, specificity and accuracy of the two methods was compared.Results:The Gm I value of BALF and the IgG level of blood in invasive pulmonary aspergillosis group were lower than those in chronic pulmonary aspergillosis group: 0.65 ± 0.09 vs. 0.98 ± 0.12, (118.95 ± 12.31) kAU/L vs. (147.63 ± 15.32) kAU/L, and there were significant differences ( P<0.05). The positive predictive rate and negative predictive rate in combined detection of detection of GMI and IgG in BALF and blood were significantly higher than those in the single detection of GMI and IgG in BLAF and blood: 92.50%(37/40) vs. 61.90%(26/42) and 61.54%(24/39), 88.24%(30/34) vs. 53.13%(17/32) and 51.43%(18/35), and there were significant differences ( P<0.05). There was a certain correlation between the severity of pulmonary aspergillosis and the Gm I value of BALF and the IgG level of blood aspergillus fumigatus. The sensitivity and accuracy of the diagnosis in combined detection of Gm I and IgG in BALF and blood were higher than those in the single detection of Gm I and IgG in BALF and blood: 92.86%(39/42) vs. 65.00%(26/40) and 67.57%(25/37), 83.78%(62/74) vs. 75.68%(56/74) and 75.68%(56/74), the diagnostic specificity was lower than that of the single detection of GM I and IgG in BALF and blood: 71.88%(23/32) vs. 88.24%(30/34) and 83.78%(31/37), and there were significant differences ( P<0.05). Conclusions:There is a certain correlation between Gm in BALF and aspergillus fumigatus IgG in blood and the symptoms of pulmonary aspergillosis. The combined detection of Gm in BALF and aspergillus fumigatus IgG in blood is of great significance for the clinical diagnosis and treatment of pulmonary aspergillosis.

OBJECTIVETo investigate the incidence and risk factors for hypertension among taxi drivers working different shifts.

METHODSUsing the cluster sampling method, 415 day-shift and 304 night-shift taxi drivers in Jinan, China were selected and investigated. The influencing factors for hypertension were analyzed.

RESULTSThe incidence of hypertension in all taxi drivers was 33.2%. The incidence of hypertension in night-shift drivers was significantly higher than that in day-shift drivers (37.8% vs 29.9%, P<0.05). According to multivariate analysis, the incidence of hypertension in day-shift drivers was closely related to body mass index (BMI), working years, working hours, sleep duration, rest days, diet quality, water intake, and smoking, while the incidence of hypertension in night-shift drivers was closely related to BMI, working years, working hours, part-time job, sleep duration, rest days, and drinking.

CONCLUSIONBMI, working years, and working hours are the common risk factors for hypertension in day-shift and night-shift drivers. Sleep duration and rest days are the common protective factors. The risk factors for hypertension in taxi drivers vary with different shifts.
