This review summarizes the research progress of lncRNA in the field of parasitology in order to find new targets for the prevention and treatment of parasitic diseases.

Objective:To explore the effect and difference of percutaneous coronary intervention (PCI) and medical therapy on quality of life and cognitive function in patients with coronary heart disease (CHD),and to investigate the relationship between quality of life and cognitive function.Methods:A total of 320 patients with CHD,who underwent coronary angiography and PCI (PCI group,n=160),or underwent coronary angiography and medical therapy (drug therapy group,n=160),were selected.The quality of life was assessed by using the Health Survey Form SF-36 (SF-36) and the Seattle Angina Questionnaire (SAQ),and the cognitive function was assessed by using the Mini-Mental State Examination (MMSE).General data of patients were collected on the day of coronary angiography.Telephone follow-up was conducted in 1 month after treatment,and the outpatient review was carried out in 3 and 6 months after treatment.Results:A total of 309 valid questionnaires were collected.The scores of quality of life in the PCI group and the drug therapy group after treatment were both increased compared with those before treatment (both P＜0.05).The SF-36 scores of four dimensions (role physical,bodily pain,vitality and mental health) in the PCI group were all significantly greater than those in the drug therapy group (all P＜0.05).The SAQscores of two dimensions (angina stability and angina frequency) were both higher in the PCI group than those in the drug therapy group in 6 months of post-operation (all P＜0.05).There was no significant difference in cognitive function before and after the treatment in the 2 groups (P＞0.05).There was no significant difference in cognitive function between the PCI group and the drug therapy group (P＞0.05).In the PCI group,physical function,role physical,bodily pain,and role emotional were positively correlated with cognitive function (r=0.207,0.182,0.184,0.176 respectively,all P＜0.05).In the drug therapy group,there was no correlation between quality of life and cognitive function.Conclusion:The quality of life for the patients is improved in the PCI group and the drug therapy group,but the improvement degree in the PCI group is more obvious.Both PCI and drug therapy do not result in the decrease of cognitive function,and there is no difference between the 2 groups.There is positive correlation between quality of life and cognitive function in the PCI group,there is no correlation between quality of life and cognitive function in the drug therapy group.

OBJECTIVETo investigate the expression and the distribution of human beta defensin (hBD)-4 in healthy gingiva.

METHODSHealthy gingival specimens were collected. The expression of hBD-4 peptides in 18 gingival specimens were detected by immunohistochemistry. The hBD-4 mRNA were determined in freshly isolated gingival tissue by real time reverse transcription-polymerase chain reaction (real time RT-PCR) in 30 gingival specimens.

RESULTSIn 18 gingival specimens, hBD-4 peptides were expressed in 13 gingival specimens. In 30 gingival specimens, hBD-4 were detected in 4 gingival specimens by real time RT-PCR.

CONCLUSIONThe distribution and the expression levels of hBD-4 are different in healthy gingiva. This result may suggest that the hBD-4 play a role in maintaining the periodontal health.

Objective:To investigate the role and mechanism of miR-143 in the proliferation and migration of gastric cancer (GC) cells. Methods:Western blot was performed to detect the expression level of avian erythroblastosis oncogene B-3 (ERBB3) in GC tissues, paired non-cancerous tissues, and SGC7901 GC cells. RT-qPCR was conducted to determine the mRNA and miR-143 of ERBB3 quantita-tively. Bioinformatics tools were used to predict the target gene of miR-143. Luciferase reporter assay was carried out to confirm the predicted target gene. Transwell and EdU assays were applied to observe the migration and proliferation of SGC7901 GC cells transfect-ed with miR-143 mimics/inhibitor/NC mimics/inhibitor. Results:Compared with the expression levels of ERBB3 and miR-143 in the paired non-cancerous tissues, the expression level of ERBB3 was upregulated and the expression level of miR-143 was downregulated in GC tissues. In the prediction of the potential target gene, miR-143 could bind to a specific sequence of the 3′-untranslated regions (UTR) of the mRNA of ERBB3. This finding was supported by luciferase reporter assay results. In vitro, ERBB3 protein expression and cell migration and proliferation were suppressed significantly in the SGC7901 cells transfected with miR-143 mimics. By contrast, these processes were remarkably enhanced when the cells were transfected with miR-143 inhibitor. Conclusion:miR-143 can suppress the migration and proliferation of GC cells by downregulating the expression of ERBB3.

Objective To analyze the risk factors of cerebral microbleeds (CMBs) in acute cerebral infarction patients. Methods We consecutively included 255 acute cerebral infarction patients who were admitted in Neurology Department of the First Affiliated Hospital of Fujian Medical University from January 2014 to December 2016. According to the number and location of CMBs, the patients were divided into infratentorial, cortical and deep cerebral groups, each of which included non-mild and moderate-severe subgroups. The differences of the level of glomerular filtration rate (eGFR) and some common arteriosclerotic risk factors were analyzed between subgroups, and the multiple logistic regression analysis was performed. Results A total of 140 subjects (54.9%) had CMBs. In the infratentorial group, the proportion of patients who were with low eGFR level in the moderate-severe CMBs subgroup was higher than in the non-mild CMBs subgroup (P=0.024). The low eGFR level (OR=3.874, 95% CI:1.261～11.901, P=0.018) and the long duration of hypertension (OR=2.128, 95%CI: 1.004～4.510, P=0.018) were the independent risk factors of the moderate-severe infratentorial CMBs. Conclusion The low eGFR level and long duration of hypertension are risk factors for the moderate and severe infratentorial CMBs after acute ischemic stroke.

Objective To summarize the phenotypic spectrum of cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) in Fujian population,evaluate the efficiency of the scale and try to adjust it.Methods Thirty-eight CADASIL patients and 64 CADASIL-like patients were recruited based on the CADASIL scale and gene tests,who visited the First Affiliated Hospital of Fujian Medical University and Fujian Neurology Research Institute from May 2011 to November 2017.Their clinical and neuroimaging characteristics were analyzed.Results The migraine,migraine with aura,transient ischemic attack / stroke,early onset age,psychiatric disturbances,cognitive decline,leukoencephalopathy,subcortical infarcts showed no statistically significant differences between the two groups.Instead,compared with CADASIL-like patients (10/64,15.6％;47/64,73.4％;10/64,15.6％),CADASIL patients demonstrated higher percentages of temporal pole involvements (13/38,34.2％;x5=4.716,P=0.030),external capsule involvements (36/38,94.7％;P=0.008) and family history in at least two generations (13/38,34.2％;x2=4.716,P=0.030).According to the scale,the scores showed statistically significant difference between CADASIL (14.84 ± 3.03) and CADASIL-like patients (13.34 ± 3.31;t=2.282,P=0.025) with an area under receiver operating characteristic curve of 0.622.Conclusions CADASIL showed no specific symptoms in Fujian population.The neuroimaging features were proposed to be focused on,especially the external capsule involvements.CADASIL scale could improve diagnostic efficiency,but still needs to be adjusted for Fujian population.The weight value of migraine,migraine with aura and cognitive decline was suggested to be decreased.

Cell-free DNA (cfDNA) is the DNA fragment existing in human extracellular fluid. In specific physiological process (such as pregnancy) or pathological conditions (such as human malignancies), the contents of cfDNA in extracellular fluid will abnormally change. The contents and molecular characteristics of cfDNA make it have the potential as a kind of biomarker for diseases′ diagnosis. With the development of cfDNA detection technology such as sequencing and mass spectrometry, liquid biopsy based on cfDNA detection has been widely used in clinical tumor diagnosis, tumor treatment, prenatal examination, and research in autoimmune diseases. A systematic summary of the latest research progress in the development of cfDNA detection technology and the clinical application of liquid biopsy, as well as the research progress of cfDNA in the diagnosis and treatment of related diseases is summarized in this review.

【Objective】 To investigate changes in thalamus structure and function and their associations with cognitive impairment in patients with amyotrophic lateral sclerosis (ALS). 【Methods】 3D high-resolution structural imaging and resting-state fMRI were applied in 78 ALS patients and 49 healthy volunteers. The shape of the thalamus was assessed using a vortex analysis and functional connectivity between the thalamus subregion and cortex was evaluated by a seed-based correlation analysis. Partial correlation analysis was used to evaluate the correlation between focal thalamus alterations and clinical assessments. 【Results】 Compared with the control group, vertex analysis showed significant atrophy in the prefrontal and temporal subregions of bilateral thalamus in the ALS group. Patients exhibited increased functional connectivity of motor-sensory ROI with the right motor cortex, of temporal ROI with the bilateral lateral occipital cortex, precuneus and right temporal subregion. In contrast, decreased function connectivity was found mainly between temporal ROI and paracingulate gyrus, left dorsomedial prefrontal lobe and left caudate. Partial correlation analysis showed that the functional connectivity of the precuneus, paracingulate cortex, left caudate nucleus and left prefrontal lobe was correlated with multiple cognitive performances. 【Conclusion】 Selective damage of thalamic structure and function in ALS plays an important role in cognitive and behavioral disorders.
