Objective: To analyze the characteristics of pneumoconiosis patients and the basic status of medical treatment. Methods: Research objects were chosen by stratified sampling method and typical survey method from existing pneumoconiosis patients in China. The survey was carried out from March 2017 to January 2018 in nine provinces including provinces from east, medium and western region in China. Source of pneumoconiosis cases were inpatient cases, outpatient or physical-examined cases and household-investigation cases. The survey mainly included demographic and sociological characteristics, economic status, occupational history and dust exposure history, disease status, work-related injury insurance and social security status and related indicators of pneumoconiosis treatment. Results: Investigated 1037 pneumoconiosis cases which included 186 (19.9%) household-investigation cases, 212 (20.4%) outpatient or physical-examined cases and 639 (61.7%) inpatient cases. Demographic and sociological characteristics, individual monthly income, economic source, occupational history and work-related injury insurance were statistically significant among different source of pneumoconiosis patients (P<0.05) . Among all of the household-investigation cases, there were 74 cases (40.2%) had no income, 117 cases (62.9%) used to work in private enterprises, 36 cases (19.4%) had work-related injuries insurance, 95 cases (51.1%) were at three phase of pneumoconiosis, 108 cases (59.0%) haven't had any drugs for pneumoconiosis. 65 cases (39.4%) haven't went to the clinic, 53 cases (28.5%) hadn't seek medical advice although they needed medical treatment very much. Among all of the outpatient or physical-examined cases, there were 95 cases (46.1%) had no income, 36 cases (17.0%) had work-related injuries Insurance, 139 cases (65.6%) went to the clinic for treatment of pneumoconiosis, 81 cases (38.2%) went to the clinic for more than ten times. Among all the inpatient cases, 310 cases' (49.3%) personal monthly income was above 2000 yuan, 352 cases (55.1%) had work-related injuries Insurance, 588 cases (92.2%) were taking drugs for treatment of pneumoconiosis, 153 canses (24.2%) had hospitalization for than ten times. Conclusion Household-investigation cases have lower economic conditions, lower rates of Insurance coverage for work-related injuries, severer pneumoconiosis and higher clinical service utilization. Clinical or physical-examined cases have lower economic conditions, lower rates of Insurance coverage for work-related injuries and higher clinical service utilization. Hospitalized cases have better economic conditions, higher rates of insurance coverage for work-related injuries and higher hospitalization service utilization.

Objective:To investigate the efficacy and safety of recombinant tissue plasminogen activator (rt-PA) in patients with wake-up ischemic stroke (WUIS) of anterior circulation non-major arteries.Methods:Sixty-seven patients with WUIS of anterior circulation non-major arteries (time from falling asleep/last use of bathroom at night to intravenous thrombolysis≤9 h and >4.5 h) admitted to Department of Neurology, Beijing Shijingshan Hospital and Department of Neurosurgery, Beijing Muyangliu Hospital from January 1 st, 2017 to December 31 st, 2021 were chosen; these 35 patients accepted routine antiplatelet therapy after intravenous thrombolytic therapy were chosen as control group, and the other 32 patients accepted rt-PA arterial thrombolysis after intravenous thrombolytic therapy were chosen as study group. Vascular recanalization after arterial thrombolysis was observed in study group (cerebral infarction thrombolysis grading 2 and 3: good vascular recanalization). Neurological deficit improvement during treatment, clinical prognoses (modified Rankin scale scores of 0-2: good prognosis) and hemorrhagic transformation incidence 3 months after treatment were compared between the 2 groups. Results:The vascular thrombolytic recanalization rate of study group was 81.25% (26/32). Patients in study group had significantly decreased National Institute of Health stroke scale scores compared with those in control group 1, 7, and 14 d after thrombolytic therapy ( P<0.05). The good prognosis rate of study group (62.50%, 20/32) was significantly higher than that in control group (37.14%, 13/35, P<0.05). No significant difference in hemorrhagic transformation rate was noted between the 2 groups (15.6% [5/32] vs. 5.71% [2/35], P>0.05). Conclusion:Patients with WUIS of anterior circulation non-major arteries (time from falling asleep/last use of bathroom at night to intravenous thrombolysis≤9 h and >4.5 h) benefit from arterial thrombolysis with rt-PA, and risk of secondary intracerebral hemorrhage is not obviously increased.

Objective: To investigate the expression and role of LINC00052 during glycidyl methacrylate (GMA) -induced malignant transformation of 16HBE cells. Methods: Human bronchial epithelial (16HBE) cells were divided into GMA transformation group and corresponding DMSO control group, and the 10th, 20th and 30th generation cells of each group were collected LncRNA microarrays were used to analysis expression of LINC00052 in different stage of malignant transformation. Bioinformatics analysis was applied and the relative expression of LINC00052 and its potentially target genes was detected by real-time quantification PCR (qPCR) . Results: The results of microarray analysis showed that LINC00052 was up-regulated by 1.32-fold, down-regulated by 1.64-fold and down-regulated by 4.92-fold in the malignant transformation early (P10) , middle term (P20) and late (P30) , respectively, The results of qPCR showed that compared with the DMSO control group, the expression of LINC00052 was up-regulated by 1.55 times, down-regulated by 1.20 times and down-regulated by 2.35 times in P10, P20 and P30, respectively, and the difference was statistically significant (P<0.05) . There was a statistically significant difference in the relative expression of NTRK3 between the GMA transformation group of P10 and P30 generations with the corresponding DMSO control group (P<0.05) . Conclusion LINC00052 is highly expressed in early time of GMA-induced malignant transformation of 16HBE, and down-regulated in the middle and last stage of malignant transformation and may play a protective role in GMA-induced malignant transformation of 16HBE by influencing the expression of its target gene NTRK3.
