Objective To determine the cut-off points of Psychological Distress Scale of Cancer Patients by using the ROC curve, in order to provide reference for clinical application of it. Methods A questionnaire containing both the Psychological Distress Scale of Cancer Patients and Symptom Checklist-90 (SCL-90) were filled by 364 cancer patients in Beijing Cancer Hospital. Later the cut-off points of the four latitudes of the Scale were evaluated by ROC curve through comparing the two scales. Results By using the latitudes of the SCL-90 scale as a reference, the areas of all the four latitudes of the Scale were:anxiety (0.815, P<0.01); depression (0.790, P<0.01); interpersonal disability (0.829, P<0.01);suspiciousness (0.670, P<0.01) respectively. The following cut-off points could result in the most ideal sensitivity and specificity: 11 for anxiety; 14 for depression; 7 for interpersonal disability and 4 for suspiciousness. Conclusions The Psychological Distress Scale of Cancer Patients can provide great values to the diagnosis of psychological problems related with anxiety, depression, and interpersonal disability, while low valuable reference for diagnosis of suspiciousness. It can provide good diagnosis value which contributes to evaluation of psychological problems of cancer patients.

Objective: To investigate the changes in the levels of interleukin-6 (IL-6) and let-7e in rats induced by coal mine dust, so as to provide the basis for the mechanism of coal worker's pneumoconiosis (CWP). Methods: Sixty-four clean and healthy male Sprague-Dawley rats were randomly divided into the control group, coal dust group, mixed dust group (mixed coal and silica dust) and quartz group. The rats in the control group were exposed to 1 mL physiological saline by non-exposure tracheal perfusion, and the rats in the dust-exposed groups were exposed to 1 mL dust suspension. Rats were sacrificed by anesthesia after 1 month and 6 months, lung tissue was observed using hematoxylin-eosin staining, the pathological change in the lungs was scored using the Szapiel scoring system, the levels of IL-6 in the bronchoalveolar lavage fluid were detected using enzyme-linked immunosorbent assay, and the expression of let-7e was determined by quantitative real-time PCR. Results: A month after exposure, a small amount of coal spots and inflammatory exudation were observed in the lung tissue of the coal dust group and the mixed dust group. The quartz group showed tissue structure destruction and mild fibrosis and thickening of alveolar septum. Six months after exposure, there were more coal spots and slightly thickened alveolar septum in the coal dust group, and hyperplasia of pulmonary interstitial fibers, destruction of alveolar structure and silica nodules were observed in the mixed dust group. In the quartz group, the alveolar structure was obviously destroyed, the interstitial fiber proliferation was significant and silica nodules were seen. Two-factor analysis of variance showed that the interaction between duration of exposure and dust type significantly influenced the pathological score of lung tissue, IL-6 levels, and let-7e expression levels (P<0.05). Under the same dust type, the pathological score of lung tissue and IL-6 levels were higher at 6 months after exposure than at 1 month, while the relative expression of let-7e was lower at 6 months after exposure than at 1 month (all P<0.05). Under the same duration of exposure, the pathological score of lung tissue and IL-6 levels were higher in the dust-exposed groups than in the control group, while the relative expression of let-7e was lower in the dust-exposed groups than in the control group (all P<0.05). Conclusions Coal dust can cause an increase in levels of IL-6 and a decrease in let-7e expression in rats. The type of dust and duration of exposure can interactively affect IL-6 and let-7e.

Objective To investigate the role of TLR4/NF-κB signaling pathway under the action of TAK-242 in the cardiomyocyte apoptosis after coronary micro-embolism (CME) in rats.Methods Fortyfive rats were randomized (random number) into three groups:sham operation,CME and CME plus TAK242 groups (n =15 per group).CME was induced by injecting polyethylene microspheres (42 μm) into the left ventricle except the sham group.CME plus TAK-242 group was treated with TAK-242 (2 mg/kg) via the tail vein of mice 30 min before CME modeling.Cardiac function was evaluated 6 h after operation.Tissue biopsy was stained with HBFP to measure the size of infarction area.TUNEL assay was used to detect cardiomyocyte apoptosis.Western blot and qPCR were used to evaluate the protein levels and mRNA expressions of TLR4,NF-κB p65 and cleaved caspase-3,respectively.Statistical analysis was performed using one-way analysis of variance followed by LSD-t test.Results Compared with the sham group,left ventricular ejection fraction (LVEF) in the CME group was significantly decreased [(68.91 ± 4.12) ％ vs.(84.80 ± 2.51) ％,P ＜ 0.05],and the infarction area (P ＜ 0.05),the apoptosis index [(3.36 ± 0.63) ％ vs.(0.19 ± 0.08) ％,P ＜0.05],the mRNA expressions of TLR4,NF-κB p65 and cleaved caspase-3 in CME group were increased significantly (all P ＜ 0.05).Compared with CME group,LVEF in the CME plus TAK-242 group was significantly improved [(75.58 ± 5.01) ％ vs.(68.91 ± 4.12) ％,P＜0.05],and the infarction area [(8.58 ± 2.12) ％ vs.(14.65 ± 4.23) ％,P＜0.05],the apoptosis index [(1.43 ± 0.51) ％ vs.(3.36 ± 0.63) ％,P ＜ 0.05],the mRNA expressions of TLR4,NF-κB p65 and cleaved caspase-3 in CME + TAK-242 group were decreased significantly (all P ＜ 0.05).Conclusions TAK-242 effectively improved CME-induced cardiac dysfunction by regulating TLR4/NF-κB signaling pathway and then reducing the cardiomyocyte apoptosis.

ObjectiveThis clinical study is aimed to investigate whether levetiracetam (LEV) can improve electrocorticogram (EEG) in epileptic children epilepsy patients with better clinical manifestation but abnormal EEG findings.MethodsTotally 39 children from our neurological clinic with partial or complex partial epilepsy seizure were included in present study and assigned equally into three groups receiving different treatment:control group,sodium valproate (VPA) group,and LEV group.Their clinical symptoms had been controlled for over one year by carbamazepine ( CBZ),but EEG results showed clearly abnormal.Epileptiform discharges were observed in routine EEG exams half a month before recruiting.After recruiting,they continued to receive CBZ alone (control group) or co-treated with VPA ( VPA group) or LEV (LEVgroup),respectively.Six months later,EEG was taken again and results were analyzed.ResultsImprovement rate were 9.1％ ( control group),23.1％ ( VPA group),and 66.7％ (LEV group),respectively;Overall statistical difference was reached among three groups ( P＜0.01 ) and between control group and LEV group( P＜0.012 5 ),but no statistical difference between control group and VPA group was reached ( P＞0.0125).ConclusionCo-treatment of LEV in child epilepsy patients receiving CBZ can significantly decrease abnormal EEG discharge frequency during interictal period.

Objective: To clarify the importance and practical significance of the standardized rate in primary healthcare work by comparing the differences in the prevalence of myopia in districts in Beijing before and after standardization. Methods: This study recruited a total of 41 029 students from 107 primary and secondary schools and 35 kindergartens from the 16 districts of Beijing municipality. All participants underwent distance vision and refractive testing. The presence of myopia was defined as naked eye vision of <5.0 and non-ciliary muscle paralysis under computer optometry with a spherical equivalent objective refractive error of <-0.50 diopters (<-0.50 D). The student composition outlined in the 2018-2019 Beijing Education Development Statistics Summary was used as a standard group to standardize the prevalence of myopia in students from various districts of Beijing. The difference in the pre-and post-standardization rates was used to compare the change in myopia in each district before and after standardization. Results: In 2018, the prevalence of myopia in students from Beijing was 57.3%. Stratified by school period, the prevalence of myopia in preschool, primary school, junior high school, ordinary high school, and vocational high school students was 12.1%, 38.4%, 77.2%, 88.3%, and 73.1%, respectively. Although the prevalence of myopia in Daxing District was the highest both before and after standardization, the difference in the prevalence rate was 13.8 percentage points. The prevalence of myopia in Miyun District was the lowest before standardization. However, after standardization, the prevalence of myopia was lowest in Huairou District. Conclusion The prevalence of myopia among Beijing students is generally high. Before and after standardization, the prevalence of myopia in different districts was quite different. The results show that, in practice, the standardized prevalence can reveal the true epidemiological characteristics of specific disease.
