Objective To investigate the effects of recombinant human osteoprotegerin(rhOPG) on RANKL ,OPG protein expression in alveolar bone tissue of rats with periodontitis to provide the experimental evidence for the application of rhOPG in pe‐riodontitis treatment .Methods Totally 22 Wistar rats were enrolled .The random number table was adopted to select two healthy rats as the healthy group .The rest 20 rats were selected as the experimental group for establishing the rat models of periodontitis , and then subdivided into the experimental control group (n=10) and rhOPG group (n=10) .Rats in the rhOPG group were locally injected by rhOPG 10 mg/kg at periodontal pocket gap of maxillary second molar ,while those in the experimental control group were injected by sterile water for injection at the same site and some volume .The streptavidin‐perosidase(SP) method was em‐ployed to detect the expression of RANKL ,OPG protein in alveolar bone tissue .Results Compared with the healthy group ,the ex‐pression levels of OPG in alveolar bone tissue of rats in the experimental group were lower with statistically significant difference (P<0 .05) ,while the difference of RANKL expression levels between the two groups showed no statistical significance(P>0 .05) . Compared with the experimental control group ,the expression level of OPG protein in alveolar bone tissue of rats in the rhOPG group was significantly up‐regulated ,while that of RANKL protein was significantly down‐regulated(P<0 .05) .The OPG expres‐sion level after treatment in the rhOPG group was markedly enhanced ,while the RANKL expression level was reduced compared with before treatment ,the difference was statistically significant (P<0 .05) .Conclusion rhOPG may regulates the expression of RANKL and OPG in alveolar bone tissue of rats with periodontitis .

Objective To study the relationship between viral infection and chronic obstructive pulmonary disease (COPD),and the effect of viral infections on the changes of Th1/Th2 in COPD patients. Methods The se-ra from 81 patients with acute exacerbations of COPD,25 patients with stable COPD and 22 healthy subjects were tested for specific IgM of respiratary syncytial virus(RSV) ,herpes simplex virus type 1 (HSV-1), parainfluenza vi-rus (PIV), adenovirus (ADV) and cytomegalovirus (CMV) by indirect enzyme-linked immunosorbent assay (ELISA). Supernatant INF-γ and IL-4 cultured with PHA were determined. Results The positive rates of IgM in patients with acute exacerbations of COPD compared with those in patients with stable COPD and healthy subjects were significantly different(P <0.001 ). The level of INF-γ, and IL-4 in patients with acute exacerbations of COPD and stable COPD compared with normal control group;the level of INF-γ (242±43) and the of IL-4(42±9) in pa-tients with acute exacerbations of COPD was not significantly different as compared with the level of INF-γ( 198±32) and the level of IL-4(56±11 ) in patients with stable COPD (P<0.05), but the level of INF-γ was increased (90±18)and IL-4 was decreased (141±24) in control group (P<0.05). Compared with those in IgM negative group, the levels of INF-γ were significantly higher and the levels of IL-4 were significantly lowerIL-4 in lgM positive group( P<0.01 ). Conclusion Virus infection is a rather important factor in acute exacerbations of COPD, and COPD is characterized by a predominance of Th1-type response,and there is more significant Th1 response predomi-nance in COPD with virus infection.

Objective: To observe the influence of acupuncture at Zusanli (ST 36) and Xuanzhong (GB 39) on cerebral vasomotoricity of ischemic stroke and its possible mechanism.Methods: All the appropriate cases were randomly divided into treatment and control groups with 80 cases in each group. The routine treatment of cerebral apoplexy was given to the two groups. Zusanli (ST 36) and Xuanzhong (GB 39) were added to the treatment group. The change of velocity of blood blow of the cerebral central artery was observed by transfrontal Doppler ultrasound detecting method before and after treatment to evaluate the cerebral basomotoricity of the patients. Results: The cerebral vasomotoricity in the treatment group was greatly improved compared with pre-treatment (P＜0.05) and there was a significant difference compared with the control group (P＜0.05). Conclusion: Acupuncture at Zusanli (ST 36) and Xuanzhong (GB 39) could obviously improve the cerebral vosomotoricity of the patients with cerebral ischemic stroke, which might be one of the action mechanisms of acupuncture treatment for cerebral ischemic stroke.

Objective: To investigate the efficacy of enticavir and lamivudine in preventing rituximab-associated hepatitis B virus(HBV) reactivation in patients with B-cell non-Hodgkin lymphoma complicated with resolved hepatitis B during chemotherapy. Methods: This retrospective study included 216 B-cell non-Hodgkin lymphoma patients with complete data from January 2012 to January 2018 treated in 3 hospitals.Of 78 patients with resolved hepatitis B, they were divided into lamivudine prophylactic group(17 cases), entecavir prophylactic group(11 cases) and control group(50 cases). The changes of HBVM, HBV DNA and liver function before or after rituximab combination chemotherapy were analyzed.The incidence of HBV reactivation, liver function injury and chemotherapy delay were compared. Results: Compared to the other 71 patients, 7 cases experienced HBV reactivation in 78 patients with resolved hepatitis B. There were no statistically significant differences between the two groups in patient demographics, pathological pattern, chemotherapy regimen.Six patients in the control group developed HBV reactivation(12%) and 1 patient in lamivudine prophylactic group(5.88%), none had HBV reactivation in enticavir prophylactic group.There was statistically significant difference among three groups(Fisher P=0.016). A total of 7 cases experienced HBV reactivation in 78 patients with resolved hepatitis B respectively, 2 cases in the first chemotherapy period, 2 cases in the third chemotherapy period, 1 case in the fifth chemotherapy period, the last one occurred after the completion of chemotherapy.Four patients had HBsAg reverse seroconversion, occurred in the 1, 3, 5 cycles during and after the completion of chemotherapy.Twenty patients (40.0%) experienced liver function parameters abnormal in the control group, 4 cases(23.5%) in lamivudine prophylaxis group, 2 cases (18.2%) in enticavir prophylaxis group during chemotherapy. Conclusion Antiviral prophylaxic therapy can potentially prevent rituximab associated HBV reactivation in patients with resolved hepatitis B. Entecavir can more reduce the risk of rituximab associated HBV reactivation than lamivudine.

Objective:To ascertain the activity concentration of gross α and β in foods around Fuqing nuclear power plant (NPP) site.Methods:Totally 167 food samples of 25 kinds within 6 categories were collected from the surveillance areas and control areas around Fuqing NPP site. The total radioactivity was analyzed using the food samples. Paired rank sum test was used to determine the influence of the operation of Fuqing NPP on the total radioactivity in foods in surrounding areas. The multiple local rank sum test was used to assess the difference in total radioactivity in different types of foods.Results:The average gross α in poultry meat, vegetables, crops, aquatic products, milk and tea was 0.65, 1.96, 1.41, 3.80, 1.33, 7.67 Bq/kg in surveillance areas and 0.56, 3.24, 2.04, 3.70, 2.24, 9.05 Bq/kg in reference areas, respectively, around Fuqing NPP site. The average gross β (subtracting 40K) in poultry meat, vegetables, crops, aquatic products, milk and tea was 7.0, 10.5, 6.1, 23.5, 24.7, 8.6 Bq/kg in surveillance areas and 7.4, 8.3, 14.5, 22.1, 21.3, 11.0 Bq/kg in reference areas, respectively, around Fuqing NPP site. The Wilcoxon paired rank test showed that there was no significant difference in the gross α and β in foods between surveillance and reference areas around Fuqing NPP site ( P>0.05). The Kruskal-Wallis H test showed that the radioactivity of gross α and β in different foods was statistically significant ( χ2=23.325, 13.918, P<0.05). Conclusions:The increase was not found in total radioactivity in the surrounding foods since the operation of Fuqing NPP in 2015.

OBJECTIVE: To report a patient with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) manifesting as lumbago, hunchback and Parkinson's syndrome. METHODS: A 49-years-old male CADASIL patient was reported. Results of clinical examination, neuroimaging and genetic testing were analyzed. His family members were also subjected to genetic testing. Related literature was reviewed. RESULTS: The patient had no typical symptoms of CADASIL such as headache, repeated stroke, dementia and emotional disorders, but progressive Parkinson's syndrome, late onset lumbago, hunchback, dysphagia, and diplopia. Brain MRI showed left basal ganglia and external capsule lacunar infarction. Genetic testing revealed a point mutation c.1630C>T (p.R544C) in exon 11 of the NOTCH3 gene. A heterozygous mutation was detected in the same gene in his mother, elder sister and younger brother, all of whom showed different clinical phenotypes. CONCLUSION The clinical features of CADASIL are heterogeneous. Lumbago, humpback, and Parkinson's syndrome may be a rare clinical phenotype of CADASIL.
