ABSTRACT

OBJECTIVE@#To analyze the clinical features and genetic basis for a Chinese pedigree affected with hereditary dyschromatosis symmetrica hereditaria (DSH).@*METHODS@#Peripheral blood samples of the proband and his mother were collected and subjected to PCR and Sanger sequencing.@*RESULTS@#The patient has conformed to the typical pattern of DSH and manifested with hyperpigmentation, hypo- and hyperpigmentation spots on the back of hands, feet and face. Sanger sequencing confirmed that the proband and his mother have both harbored heterozygous splicing variant c.2762+1G>T in exon 9 of the ADAR gene, which was unreported previously. The same variant was not detected among 100 healthy controls. According to the guidelines of the American College of Medical Genetics and Genomics, the variant was predicted to be pathogenic (PVS1+PM2+PP4).@*CONCLUSION@#The c.2762+1G>T variant of the ADAR gene probably underlay the DSH in this pedigree. Above finding has enriched the spectrum of ADAR gene mutations.

ABSTRACT

Objective To study the 137Cs source term from the Fukushima Daiichi nuclear power plant,based on inverse modeling,so as to provide reference for accident assessment and radiation protection.Methods The 137Cs source term was estimated by means of inverse modeling of nuclear accidents based on variational data assimilation combined with truncated total least squares (TTLS-VAR).The environmental monitoring data was balanced,and the dispersion model operator and monitoring data vector were corrected,in order to reduce the influence from atmospheric dispersion model error,and then improve the accuracy of inverse modeling of source term.Results The total amount of 137Cs released was estimated to be 1.74× 1016-3.73× 1016 Bq,with the highest peak of release rates estimated appearing on March 18,2011 and the average release rate in exceed of 1.00× 1012 Bq/s.The estimated total amount of 137 Cs was close to the data published by IAEA and UNSCEAR.Also,the estimated release sequences were in good consistent with Japanese analytical results of source terms and sequence of events.The highest peak of the estimated release rate curve corresponds to the leakage incident of unit 3.Conclusions In this study,the 137Cs source term from the Fukushima Daiichi nuclear power plant is estimated by using TTLS-VAR inverse modeling,which could provide the basis for accident assessment and radiation protection.

ABSTRACT

Congenital lower urinary tract obstruction in the fetus and is rare in neonates,but it is identified in-creasingly in the era of prenatal sonography and resulted in substantial perinatal mortality with lifelong morbidity. Poste-rior urethral valves,urethral atresia,and prune - belly syndrome are the frequently reported causes of lower urinary tract obstruction. Despite the completion of a randomized trial,the benefit of prenatal intervention with vesicoamniotic shunt placement remains unclear. The management of these disease in fetus and newborns requires appropriate urinary tract decompression,subspecially support,and definitive diagnosis with endoscopy and radiography. Now,the recent progress of diagnosis and treatment of congenital lower urinary tract obstruction were reviewed.

ABSTRACT

OBJECTIVE@#To explore the roles of otolith organs in the occurrence and recurrence of primary benign paroxysmal positional vertigo (BPPV) by vestibular evoked myogenic potential (VEMP) test.@*METHOD@#We enrolled 17 recurrent primary BPPV patients and 42 non-recurrent primary BPPV patients between September 2014 and November 2014. All patients underwent VEMP tests, including cervical vestibular evoked myogenic potential (cVEMP and ocular vestibular evoked myogenic potential (oVEMP) tests. The abnormal case was defined as non-elicitation or asymmetry rate between bilateral sides is larger than 29%.@*RESULT@#Significant difference was found in abnormal rate between cVEMP and oVEMP (P 0.05). No significant difference was found in sex and age between recurrent and non-recurrent groups (P > 0.05).@*CONCLUSION@#The impairment of otolith organs, especially the utricle, is related to primary BPPV. Dysfunction of utricle may play a role in recurrence of BPPV. Recurrence of BPPV is not correlated with sex and age.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of ERK1/2 inhibitor AZD8330 on human Burkitt's lymphoma cell line Raji cells and its mechanism.</p><p><b>METHODS</b>Raji cells were treated with different concentrations of AZD8330. CCK-8 was used to detect the cell viability. The apoptosis rate of Raji cells was detected by flow cytometry using Annexin V/PI-staining. Real-time PCR was used to assess the expression of Bcl-2, Bcl-xl, caspase-3 and VEGF genes. The protein expression level of Bcl-2, Bcl-xl, caspase-3 and p-ERK1/2 was tested with Western blot.</p><p><b>RESULTS</b>The cell survival rate decreased to(62.09±0.86)%,(50.06±1.33)% and (39.13±2.34)% respectively after cells were treated with AZD8330 at 1.00 μmol/L in vitro for 24 h, 48 h and 72 h, and statistically significant differences were observed in groups with different time of treatment(P<0.05). Apoptosis of cells treated with AZD8330 at 0.10, 1.00, 10.00 μmol/L in vitro for 24 h, 48 h and 72 h was analyzed, and the statistically significant differences were observed in groups of different time and concentration treatment (P<0.05). AZD8330 induced Raji cell apoptosis and upregulated expression of Bcl-2, Bcl-xl, VEFG and decreased the expression of caspase-3 in a dose and time dependent manner, and statistically significant differences were observed in groups of different time and concentration treatment (P<0.05). At the same time, the Bcl-2, Bcl-xl and p-ERK1/2 proteins expression is suppressed obviously, but the expression of caspase-3 protein increased.</p><p><b>CONCLUSION</b>AZD8330 induces cell apoptosis by down-regulating the activation of ERK1/2 signal transduction pathway in Burkitt's lymphoma cell line Raji cells in a dose and time dependent manner.</p>

ABSTRACT

Objective: To investigate the effect of cobalt chloride (CoCl2) on transgene expression and viral particle titers in tumor cells infected by conditionally replicating adenovirus expression vector with hypoxia response elements(HRE)-regulated E1AE1B expression (Ad-5HRE-E1AE1B-RFP) and non-HRE regulated replication-deficient adenovirus expression vector (Ad-EGFP, Ad-Luc) in vitro and in vivo. Methods: Ad-5HRE-E1AE1B-RFP had five duplicated HRE and mini CMV acted as a promoter to drive E1AE1B expression and constitutive expression of RFP as reporter. The hypoxia model was optimized by exposing tumor cells to different concentrations of CoCl2. The hypoxia-inducible factor 1 alpha (HIF-1α) protein expression was determined by Western blotting. Under the optimized hypoxia model, the positive expression of exogenous gene and virus replication of Ad-5HRE-E1AE1B-RFP or Ad-EGFP-infected tumor cells were examined by conversed microscopic observation, FACS analysis and plaques formation test. Furthermore, transgene expression induced by combined application of hypoxia-inducible replicative adenovirus and replication deficient adenovirus (Ad-Luc) was also evaluated by examining the lucifererse activity in xenografted tumor models in nude mice by micro PET. Results: Western blotting results showed that CoCl2 at 0.4 and 0.08 μg/mL could stabilize and acumulate HIF-1α protein in gastric cancer SGC7901 cells, which could better mimic hypoxia condition. The microscopic observation and FACS analysis showed that CoCl2 at 0.4 μg/mL could remarkably increase the transduction efficacy of Ad-5HRE-E1AE1B-RFP, which was verified by significant increase in the percentage of positive expression of exogenous gene RFP and fluorescence intensity. But plaques formation test showed that Ad-5HRE-E1AE1B-RFP had no replication. CoCl2 0.4 μg/mL augmented the tranduction efficacy and expression levels of non-HRE regulated replication deficient adenovirus Ad-EGFP and Ad-Luc. Combined intratumoral injection of Ad-5HRE-E1AE1B-RFP and Ad-Luc significantly increased the expression of Ad-Luc in nude mice.Conclusion: CoCl2 markedly enhances transgene expression of recombinant adenovirus. However, the underlying mechanism is not only related to the CoCl2-induced hypoxia, but also probably related to regulation of gene transcription.

ABSTRACT

BACKGROUND: Genetically engineered cells have been used in the replacement therapy and gene therapy. However, how to select proper donor cells, target cells, and corresponding viral vectors is the most difficult in the therapy.OBJECTIVE: To compare the transduction efficiency of recombinant adenovirus Ad5 and AdSF35, adeno-associated virus rAAV1/2 and rAAV2, and lentivirus LV in bone marrow mesenchymal stem cells (BMSCs) and exogenous gene expression level so as to select the vectors, which can efficiently transduce BMSCs.DESIGN, TIME AND SETTING: Gene engineering controlled observation, performed in the Central Laboratory, Shanghai First People's Hospital between October 2006 and March 2007.MATERIALS: Ten Sprague Dawley rats of clean grade were used to prepare BMSCs. All recombinant viral vectors carded enhanced green fluorescent protein (EGFP) report gene. Ad5 was prepared by the Central Laboratory, Shanghai First People's Hospital. Ad5F35 was gifted by professor Qian Qi-jun from the Second Military Medical University of Chinese PLA. rAAV2 and rAAVI/2 were the products of Benyuan Zhengyang Gene Technique Co.,Ltd. LV was gifted by professor Cuo Li-be from Shanghai Institute of Biochemistry and Cytobiology, Chinese Academy of Sciences.METHODS: Rat BMSCs were in vitro isolated and cultured by density gradient centrifugation. BMSCs of passage 4 were inoculated into 24-well plate at lxlO5/well. One day later, ceils adhered to the wall and allocated to 5 groups. Ad5-EGFP [10, 100,1 000 multiplicity of infection (MOI)], Ad5F35-EGFP (10,10, 1 000 MOI), rAAVI/2-EGFP (1×104,1x10× vg), rAAV2-EGFP(1×104, 1x105vg), and LV-EGFP (30 TU) were respectively added into the 5 groups. BMSCs were transduced for 2 days with Ad virus and separately for 6 days with rAAV and LV virus.MAIN OUTCOME MEASURES: EGFP-positive expression and fluorescence intensity.RESULTS: After twenty-four hours of Ad5-EGFP transduction, EGFP-positive cells were visible under the microscope. With virus dose increasing, EGFP-positive cells increased and fluorescence intensity strengthened. Twelve days later, EGFP-positive cells gradually reduced and fluorescence intensity weakened. For Ad5F35-EGFP, its transduction was basically similar to Ad5-EGFP, but EGFP-positive cell number and fluorescence intensity were increased. After 6 days of rAAV1/2-EGFP or rAAV2-EGFP transduction, EGFP-posidve cell number and fluorescence intensity were decreased. For LV-EGFP transduction, a small amount of EGFP-positive cells could be visible on the second day, and then EGFP-positive ceils and fluorescence intensity were gradually increased until the sixth day.CONCLUSION: Ad5, Ad5F35 and LV could effectively transduce BMSCs cultured in vitro and express exogenous gene.Furthermore, transduction efficiency was correlated with virus dose in dose-dependent manner, rAAVI/2 and rAAV2 had poor/in vitro transduction efficiency.

ABSTRACT

Total hip replacement is a primary therapy for hip-joint disease.Well-matched prosthesis is important for success replacement.Biomechanical performance of the artificial joint following replacement is closely related to the service life.In addition,the effect of total hip replacement is highly correlated with acetabular anteversion angle,femoral head rotation center and eccentricity,and force.Prosthesis force includes normal stress and shear stress.The normal stress is beneficial to prosthesis fixation and force transfer,while shear stress may cause prosthesis loosening.Bone and bone mass changes surrounding the prosthesis,prosthesis loosening or dislocation,prosthesis peripheral fracture,material wearing,and infection are common complications influencing mid-and long-term effect of total hip replacement.
