ABSTRACT
Objective:To investigate the correlation between migraine and overall burden of cerebral small vessel disease (CSVD).Methods:Migraine patients who visited the headache clinic of Jiangyin People's Hospital from January 2021 to October 2021 were selected as the case group, and healthy people who had no previous primary headache of any type and matched age and sex in the same period were selected as the control group. Various CSVD phenotypes, including vasogenic lacuna, white matter hyperintensities (WMHs), cerebral microbleeds (CMBs) and enlarged perivascular space (EPVS) were detected by the multimodal MRI, and the overall burden score of CSVD was calculated. The detection rates of CSVD and its phenotypes and the overall burden of CSVD were compared between the case group and the control group. The subjects with CSVD were divided into mild group, moderate group and severe group according to the overall burden score of CSVD. The independent influencing factors of the overall burden of CSVD were identified by the ordinal multi-classification logistic regression model. Results:A total of 109 migraine patients and 100 healthy controls were enrolled. The detection rate of CSVD (65.13% vs. 46.00%; P=0.005) and the proportion of patients with severe CSVD overall burden (24.77% vs. 10.00%; P=0.005) in the case group were significantly higher than those in the control group. In terms of specific CSVD phenotypes, the detection rates of WMHs (48.62% vs. 33.00%; P=0.022) and CMBs (35.80% vs. 19.00%; P=0.007) in the case group were significantly higher than those in the control group, while there were no significant differences in vasogenic lacuna and moderate to severe EPVS. Univariate analysis showed that the overall burden of CSVD was significantly associated with age, migraine, hypertension, baseline diastolic blood pressure, low-density lipoprotein cholesterol (LDL-C) and glycosylated hemoglobin (all P<0.05). Multivariate logistic analysis showed that age (odds ratio [ OR] 3.731, 95% confidence interval [ CI] 1.051-1.217; P=0.001), migraine ( OR 2.812, 95% CI 1.045-5.124; P=0.012), hypertension ( OR 2.112, 95% CI 1.525-4.021; P=0.032), and LDL-C ( OR 2.512, 95% CI 1.541-4.312; P=0.023) were independently associated with the overall burden of CSVD. Conclusions:The detection rate of CSVD in migraine patients is higher than that in the general population, especially WMHs and CMBs. Migraine is independently associated with the overall burden of CSVD.
ABSTRACT
Objective:To explore the prognostic value of circulating tumor cell (CTC) for colorectal cancer.Method:We analyze the correlation between CTC and clinicopathological data, survival curve and overall survival.Results:The positive rates of preoperative and postoperative CTC in 181 colorectal cancer patients were 66.3% and 65.7% respectively ( χ2=0.012, P=0.912). The postoperative CTC positive rates for recurrence and non-recurrence of stage Ⅱ colorectal cancer were 29.2% and 8.0%, respectively ( χ2=4.303, P=0.038). The progress free survuval of CTC-positive and CTC-negative in postoperative stage Ⅱ colorectal cancer patients were 28.7 months and 34.0 months, respectively ( χ2=4.096, P=0.043). Conclusion:Postoperative CTC detection has predictive prognostic value for patients with stage Ⅱ colorectal cancer.
ABSTRACT
Objective:To evaluate the relationship between phosphorylation of glycogen synthase kinase-3β (GSK-3β) and high glucose-caused abolition of cardioprotection induced by sevoflurane postconditioning.Methods:H9c2 cells were incubated in normal glucose (5.56 mmol/L) DMEM culture medium or high glucose (33 mmol/L) DMEM culture medium.The cells were divided into 8 groups ( n=24 each) using a random number table method: normal control group (group NC), normal glucose-cultured hypoxia/reoxygenation (H/R) group (group NH/R), normal glucose-cultured sevoflurane postconditioning group (group NS), normal glucose-cultured GSK-3β inhibitor SB216763 group (group NSB), high glucose-cultured group (group HC), high glucose-cultured H/R group (group HH/R), high glucose-cultured sevoflurane postconditioning group (group HS) and high glucose-cultured GSK-3β inhibitor SB216763 group (group HSB). The model of cardiomyocyte H/R was established by subjecting cardiomyocytes to 3 h of hypoxia followed by reoxygenation.Immediately after onset of reoxygenation, cardiomyocytes were exposed to 2.4% sevoflurane for 30 min in Ns and HS groups.Before the beginning of reoxygenation, GSK-3β inhibitor SB216763 was added to the culture medium with the final concentration of 10 μmol/L in NSB and HSB groups.At 3 h of reoxygenation, the apoptosis rate was determined by Anexin V-PI flow cytometry, the expression of GSK-3β and phosphorylated GSK-3β (p-GSK-3β) was detected by Western blot, superoxide dismutase (SOD) activity was measured using xanthineoxidase method, and lactic dehydrogenase (LDH) activity and malondialdehyde (MDA) content were determined by colorimetric assay. Results:Compared with group NC, apoptosis rate, LDH activity and MDA content were significantly increased, and SOD activity was decreased in group NH/R and group HC, expression of GSK-3β was up-regulated, and expression of p-GSK-3β was down-regulated in group NH/R, expression of p-GSK-3β was up-regulated in group NS, and expression of p-GSK-3β was down-regulated in group HC ( P<0.05). Compared with group NH/R, apoptosis rate, LDH activity and MDA content were significantly decreased, and SOD activity was increased in group NS and NSB groups, and expression of GSK-3β was down-regulated, and expression of p-GSK-3β was up-regulated in group NS ( P<0.05). Compared with group HC, apoptosis rate, LDH activity and MDA content were significantly increased, SOD activity was decreased, expression of GSK-3β was up-regulated, and expression of p-GSK-3β was down-regulated in group HH/R ( P<0.05). Compared with group HH/R, apoptosis rate, LDH activity and MDA content were significantly decreased, and SOD activity was increased in group HSB ( P<0.05). Conclusion:The mechanism by which high glucose abolishes cardioprotection induced by sevoflurane postconditioning is related to inhibiting phosphorylation of GSK-3β.
ABSTRACT
ObjectiveTo investigate the distribution of traditional Chinese medicine (TCM) syndrome types and syndrome elements of nonalcoholic fatty liver disease (NAFLD). MethodsRelated databases (CNKI, Wanfang Dota, and VIP)were searched for articles on the syndrome differentiation of NAFLD published up to July 2020. Two investigators independently performed literature screening and collection and summarization of syndrome types based on the inclusion and exclusion criteria, and an Excel 2010 database was established after the standardization of syndrome names, re-decomposition of syndrome types, and extraction of syndrome elements. The data were imported into SPSS 25.0 statistical software for the analysis of frequency distribution. ResultsA total of 45 qualified articles were collected, with a total of 8703 cases reported. A total of 14 syndrome types were obtained after standardization, and 10 syndrome elements reflecting the nature of disease and 4 syndrome elements of disease location were obtained after the syndrome types were disassembled. Stagnation of liver Qi and spleen deficiency syndrome (26.47%) and damp-heat accumulation syndrome (22.16%) were the most common syndrome types, followed by stagnation of phlegm dampness, intermingled phlegm and blood stasis, and stagnation of liver Qi and Qi stagnation. Dampness (23.75%), Qi stagnation (19.82%), Qi deficiency (17.12%), phlegm (15.43%), and heat (12.13%) were the most common syndrome elements reflecting the nature of disease, followed by stasis, Yin deficiency, and Yang deficiency, while fire and cold were relatively uncommon. Qi stagnation and Qi deficiency (26.63%), dampness and heat (22.30%), phlegm and dampness (16.17%), and phlegm and stasis (12.19%) were the most common combinations of syndrome elements. The liver and the spleen were the most common syndrome elements of disease location, accounting for 90.95% of the constituent ratio, and the combination of the liver and the spleen with the same disease accounted for 54.01%. The combination of one, two, three, or four syndrome elements was observed, and the combination of two syndrome elements accounted for 76.03%. ConclusionStagnation of liver Qi and spleen deficiency are the basic pathogeneses of NAFLD, and liver, spleen, dampness, Qi stagnation, Qi deficiency, phlegm, and heat are common syndrome elements. Dampness, phlegm, and heat are important factors for the development and progression of this disease.
ABSTRACT
Objective To explore the clinical and neuroimaging features in a Chinese family with hereditary diffuse leukoencephalopathy with neuroaxonal spheroids (HDLS) caused by mutation of the colony stimulating factor 1 receptor gene (CSF1R). Methods The proband and another patient from a HDLS pedigree were assessed respectively through standardized clinical evaluation (medical history inquiry, physical examination),neuropsychology assessment,MRI,genetic sequencing, as well as brain PET imaging with carbon11-labelled Pittsburgh compound-B(11C-PIB). Results A HDLS pedigree with three patients was recruited to this study. Apathy, memory decline, slow behavior were the first symptoms for two of the patients. Being bedridden, urinary incontinence and epilepsy were developed at the later stage. A missense mutation c. 2381T>C(p. I794T) in exon 18 of the CSF1R gene of chromosome 5 was identified in the proband. The brain DWI illustrated multiple patchy high signal in periventricular white matter and centrum semiovale which was characterized by persistence, and the corpus callosum was affected in the early stage. Conclusion The multiple patchy high signal with persistence in periventricular white matter and centrum semiovale of DWI is helpful for the early diagnosis of HDLS.
