Objective To evaluate the efficacy and safety of Xuebijing combined with corticosteroid injection treating paraquat poisoning with regression analysis. Methods 146 patients of paraquat poisoning in 3 years were divided into two groups: control group and therapeutic group. 50 patients in the control group were treated with Methylprednisolone, while 96 patients in the therapeutic group were treated with Xuebijing injection (300～400 ml/d, intravenous drip) and Methylprednisolone. The patients' clinical symptoms, signs and the levels of white blood cell (WBC), Neutrophils (N), C-reactive protein (CRP), glutamic-pyruvic transaminase (ALT), aspartate aminotransferase (AST), serum creatinine (Scr) and arterial partial pressure of oxygen were collected. And patients did chest CT examinations every three days. All the data were compared between the two groups. Results ① The biochemical indicators of the control group in the 14th day [WBC,N,CRP, and PaO2 is (16.49±4.30), (84.22±21.07), (24.58±7.06), and (83.20±22.95) respectively]were better than those in the third day[WBC, N, CRP, and PaO2 is (19.21 ±5.34), (85.04± 12.33), (27.98±6.51), and (73.42±11.43)respectively], but there was not significant difference between them(P>0.05). While the biochemical indicators of the therapeutic group in the 14th day [WBC,N, CRP, and PaO2 is (9.16 ± 3.23 ), (70.48 ± 10.79), ( 17.48 ± 4.7), and (95.04± 11.93) respectively] were much better than those in the third day [WBC,N,CRP, and PaO2 is (16.96±9.95),(84.82±9.34), (27.34± 10.03), and (89.12±9.47) respectively], and there was significant difference between them( P< 0.05 ). ② The survival rate in the control group was 32% comparing to 67.71% in the therapeutic group, showing significant difference between the two group (x2=9.588, P<0.05) . ③ The patients' chest CT examinations in the therapeutic group were better than those in the control group. Conclusion Xuebijing injection combined with methylprednisolone had good effects m treating paraquat poisoning.

BACKGROUND:With the extensive application of cone-beam CT in oral and craniofacial surgery, a clear hyoid bone position indicator for normal population has important implications for the change of hyoid bone position before and after orthodontics. OBJECTIVE:To determine the cone-beam CT measurement range of hyoid bone position in populations aged 6-19 years from Shandong, so as to provide a reference marker for the change of hyoid bone position before and after orthodontics in local children and adolescents. METHODS:Totaly 254 healthy children (120 males and 134 females) aged 6-19 years from Shandong Province were subjected to cone-beam CT scan of the hyoid bone. Mimics10.01 was used to evaluate the linear and angular measurements of hyoid bone position, and then the normal value range was confirmed. Independent-samplet-test was used for analysis of gender difference and 95% confidence interval was calculated. RESULTS AND CONCLUSION: There were gender differences in a part of indicators of hyoid bone position among 14-15 years, 16-17 years, 18-19 years groups (P < 0.05). For children aged 12-13 years, the hyoid bone position vertical to the base of skul and upper jaw bone is lower in males than in females. For children aged 14-15 years and 18-19 years, the hyoid bone horizontal to the cervical spine is more forward in males than in females.

BACKGROUND:Bioglass has good biocompatibility and biological activity, which can be combined with calcium phosphate bone cement to form an absorbable bioglass that has the advantages of both materials and is expected to have a better use of space. OBJECTIVE:To explore the mechamism of the new type of absorbable bioglass injection for vertebral body supporting and osteogenic induction in osteoporosis rats. METHODS:Twenty-seven female Sprague-Dawley rats were selected to make osteoporosis models by bilateral ovariectomy, and after 1 month, the rats were randomized into three groups. Bone defect models were established in the lumbar L4 segment of al the rats. Rats in the experimental group were subjected to absorbable bioglass injection; rats in the control group 1 underwent polymethylmethacrylate bone cement injection; and rats in the control group 2 were given injectable calcium phosphate. Twelve weeks after implantation, the compressive strength, degradation and osteogenesis of the implant materials were detected, and levels of serum bone morphogenetic protein-2 and transforming growth factor-β were measured. RESULTSAND CONCLUSION: The compressive strength, hydroxyapatite deposition amount, and weight loss ratio in the experimental group were significantly higher than those in the two control groups (P < 0.05); the relative volume, thickness and number of bone trabeculae in the experimental group were significantly higher than those in the control groups (P < 0.05); the bone morphogenetic protein-2 and transforming growth factor-β protein levels in the experimental group were significantly higher than those in the two control groups (P < 0.05). These findings indicate that the new-type absorbable bioglass can greatly strengthen the vertebral body supporting and promote osteogenic effect in osteoporosis by enhancing the bone morphogenetic protein-2 and transforming growth factor-β protein levels.

[Objective]To investigate the prognostic value of 18F-FDG PET/CT with different metabolic parameters in newly diagnosed limited-disease(LD)small cell lung cancer(SCLC).[Methods]Retrospective analysis was carried out in the patients between June 2005 to December 2016 in our hospital confirmed of LD SCLC by pathology or cytology and comprehensive imaging. Fifty-four patients were recruited. Record the general characteristics of patients,pre-treatment KPS score,smoking status,weight loss,serum LDH,NSE,OS,PFS. All lesions(primary lesions + metastases)were sketched out within one VOI,and the SUVmax, SUVmean and SUVpeak in the VOI were automatically measured and recorded. The automatic measurement was performed by the fixed threshold method. The thresholds of tumor of MTV and TLG were 40% and 50% of SUVmax. The TLG and MTV were identified as TLG40%,TLG50%,MTV40% and MTV50% respectively. Kaplan-Meier method was used for survival analysis. All the prognostic factors were analyzed by Cox model.[Result]The median SUVmax was 13.92(2.61~43.28),the median of SUVmean was 8.31(1.71~26.85) and the median of SUVpeak was 10.51(1.49 ~ 27.48). The median of TLG40% was 340.22(16.58 ~ 2827.26),the median of TLG50%was 215.645(1.70 ~ 2270.36),the median of MTV40% was 36.71(1.15 ~ 259.47 cm3),the median of MTV50% was 19.65(0.93 ~1900.00)cm3. Univariate and multivariate analysis of metabolic index and prognosis showed that TLG50% was the prognostic factor of OS(P = 0.013),but not of PFS(P > 0.05). The SUVmax,SUVmean and SUVpeak were not the prognostic factors of OS and PFS(P >0.05).[Conclusion]The volume metabolic parameters TLG50%was the independent prognostic factor of the overall survival time of the LD SCLC. The volume metabolic parameters (TLG and MTV) of 18F-FDG PET/CT were related to the prognosis of SCLC ,which could provide the basis for individual chemotherapy.
