Objective To analyze stress distributions of alveolar bone around implants with different types of implant thread shapes and thread depths during dental immediate implantation, so as to provide references for the design and selection of implants. Methods The simplified model of mandible bone block, implants and mandibular molar were established by Geomagic Studio, SolidWorks and ANSYS Workbench, and vertical and oblique loads were applied on this model, respectively. Stress distributions on implants with different thread shape and thread depth as well as alveolar bone around implants were calculated. Results Under vertical loading, the peak stresses of implants, cortical bone and cancellous bone were in the range of 120.51-129.63 MPa, 9.94-13.25 MPa and 3.92-8.01 MPa, respectively. And the stress of cortical bone around V-shaped, rectangular, buttress or reverse buttress implant remained stable in the range of 0.40-0.45 mm thread depth. Under oblique loading, the peak stresses of implants, cortical bone and cancellous bone were in the range of 220.23-286.51 MPa, 33.39-45.08 MPa, 4.96-12.5 MPa, respectively. Among the models, V-shaped, buttress, reverse buttress implant with 0.45 mm thread depth showed the minimum stress. Conclusions The V-shaped, buttress or reverse buttress implant with a thread depth of 0.45 mm, or the rectangular implant with a thread depth of 0.40 mm had better biomechanical properties.

Objective:To explore the clinical effects of tuina therapy of Yinyang Ruyin combined with aromatherapy on insomnia and quality of life in patients receiving perichemotherapy for breast cancer.Methods:Totally 199 inpatients with insomnia who received perichemotherapy for breast cancer from June 2018 to December 2019 and met inclusion and exclusion criteria were selected and divided into the control group ( n=48) , the tuina therapy of Yinyang Ruyin group ( n=50) , the aromatherapy group ( n=52) , and the combined treatment group ( n=49) according to the computer-generated random sequence. Patients in the control group received routine care; patients in the tuina therapy of Yinyang Ruyin group received tuina therapy of Yinyang Ruyin on this basis; patients in the aromatherapy group received aromatherapy on this basis; patients in the combined treatment group received both tuina therapy of Yinyang Ruyin and aromatherapy. After 6 cycles of chemotherapy, Pittsburgh Sleep Quality Index (PSQI) , Hamilton Depression Scale (HAMD) , and Functional Assessment of Cancer Therapy: General (FACT-G) were used to evaluate the intervention effects of the four groups. Results:The amelioration rates of insomnia in the 3 and 6 chemotherapy cycles after the intervention of the tuina therapy of Yinyang Ruyin group, the aromatherapy group, and the combined treatment group were higher than that of the control group ( P<0.05) ; the amelioration rates of insomnia in the 3 and 6 chemotherapy cycles after the intervention of the combined treatment group was higher than those of the tuina therapy of control group, Yinyang Ruyin group and the aromatherapy group ( P<0.05) . The repeated measures analysis of variance showed that the main effects of intervention in the PSQI, HAMD, and FACT-G scores of the four groups were statistically different ( P<0.05) ; the time of main effects of PSQI, HAMD, and FACT-G scores was significantly different ( P<0.05) ; there was an interaction between the intervention factors of PSQI, HAMD, and FACT-G scores and the time factor ( P<0.05) . Conclusions:Tuina therapy of Yinyang Ruyin combined with aromatherapy can ameliorate the symptoms of insomnia and depression, thereby improving the quality of life of patients.

Purpose: Drug resistance is one of the main causes of chemotherapy failure in patients with small cell lung cancer (SCLC), and extensive biological studies into chemotherapy drug resistance are required. Materials and Methods: In this study, we performed lncRNA microarray, in vitro functional assays, in vivo models and cDNA microarray to evaluate the impact of lncRNA in SCLC chemoresistance. Results: The results showed that KCNQ1OT1 expression was upregulated in SCLC tissues and was a poor prognostic factor for patients with SCLC. Knockdown of KCNQ1OT1 inhibited cell proliferation, migration, chemoresistance and promoted apoptosis of SCLC cells. Mechanistic investigation showed that KCNQ1OT1 can activate transforming growth factor-β1 mediated epithelial-to-mesenchymal transition in SCLC cells. Conclusion Taken together, our study revealed the role of KCNQ1OT1 in the progression and chemoresistance of SCLC, and suggested KCNQ1OT1 as a potential diagnostic and prognostic biomarker in SCLC clinical management.

Objective To retrospectively compared the hospitalization days and hospitalization costs of patients with thyroid tumor and breast cancer between patients who accepted selective hospitalization management and patients who accepted routine hospital management, and analyze the effect of selective hospitalization management to shorten the average hospitalization days.Methods A total of 419 patients with thyroid tumor and 318 patients with breast cancer who were treated in Fujian Provincial Hospital from March 2013 to February 2016 were chosen as the study object, and they were divided into the control group and the study group according to whether accepting the selective hospitalization management. Evaluating indicators included the total hospitalization days, preoperative hospitalization days, postoperative hospitalization days and hospitalization costs.Results Compared with the control group, the average total hospitalization days [(6.56±2.94)d vs (8.09± 3.71)d,(12.44±3.91)d vs (14.73±6.66)d)] and preoperative hospitalization days[(2.42±1.94)d vs (4.17± 2.68)d,(2.98±1.70) vs (5.29±4.00)d] in the study group were all reduced (P<0.05). There was no significant difference in the postoperative hospitalization days and the average hospitalization costs between two groups ( P > 0. 05 ) . Conclusions Selective hospitalization management could effectively shorten the hospitalization days of patients undergoing selective operation, and increase beds turnover rate. So the new management method would produce good social and economic benefits for the hospital.
