Objective To observe and analyze the therapeutic effect of focal uterine adenomyosis treated with percutaneous microwave ablation by contrast-enhanced ultrasound and dynamic contrast enhanced MRI (DCE-MRI).Methods From January 2013 to July 2016,42 patients with focal uterine adenomyosis voluntarily underwent percutaneous microwave ablation in the tumor hospital of Liaocheng.Contrast-enhanced ultrasound and DCE-MRI were performed before and after percutaneous microwave ablation.The therapeutic effects of percutaneous microwave ablation in treatment of uterine adenomyosis lesions were observed.Results After percutaneous microwave ablation of the 42 cases,the ablated zone showed no enhancement with contrast-enhanced ultrasound and DCE-MRI.Contrast-enhanced ultrasound showed that the volume and ablation rate of ablated zone were (49.0±29.5) cm3 and (91.6± 7.1)％,and that of DCE-MRI were (49.4 ± 29.9)cm3 and (91.9 ± 6.7)％,respectively.The results showed that percutaneous microwave ablation could cure focal uterine adenomyosis at the rate over 90％.Contrast-enhanced ultrasoundand DCE-MRI are in accordance in observing the ablation rate.Conclusions Contrast-enhanced ultrasound can accurately show the ablation rate of focal uterine adenomyosis treated with percutaneous microwave ablation,which is quite consistent with DCE-MRI.Contrast-enhanced ultrasound has its advantages such as identifying the lesions which need immiedately supplemental ablation.

Objectives To investigate the value of hepatobiliary scintigraphy in evaluation of the hepatic uptake and excre-tion function in neonatal intrahepatic cholestasis caused by citrin deifciency (NICCD). Methods Hepatobiliary scintigraphy with SPECT was used to detect the hepatic uptake and excretion function of 12 patients with NICCD conifrmed by SLC25A13 gene analysis, and the results were compared with the results of blood biochemical tests. Results The hepatic uptake and excretion function were obviously impaired in all of 12 NICCD patients in the initial scintigraphy. The scintigraphy were performed again in 5 patients in the follow-up after treatment, and showed that the hepatic uptake and excretion function was recovered. It was sug-gested that the hepatic uptake and excretion function was consistent with the level of liver enzymes and the degree of cholestasis. Conclusions Hepatobiliary scintigraphy is of value in evaluation of the hepatic uptake and excretion function in NICCD patients.

Objective To investigate the correlation between executive function(EF) and characteristic of symptom in children with Tourette′s syndrome(TS).Methods EF were measured with Wisconsin Card Sorting Test(WCST) in 53 patients with TS,and symptom characteristics were evaluated with Achenbach Child Behavior Checklist(CBCL) and Yale Global Tic Severity Scale(YGTSS).Results Compared with healthy control,TS had poor executive performances significantly in WCST(all P

OBJECTIVE: To analyze the case characteristics of poisoning by exhaust gas of the imperfect combustion of natural gas and provide references for forensic identification and prevention of such accidents. METHODS: Twenty-two cases of poisoning by exhaust gas of the imperfect combustion of natural gas in Minhang District during 2004 to 2013 were collected. Some aspects such as general conditions of deaths, incidence time, weather, field investigation, and autopsy were retrospectively analyzed. RESULTS: In the 22 cases, there were 15 males and 16 females. The age range was between 2 and 82 years old. The major occurring time was in January or February (8 cases in each) and the cases almost occurred in small area room (21 cases). There was wide crack next to the exhaust port when the gas water heater was been used in all cases. CONCLUSION There are more prone to occurrence of exhaust gas poisoning of imperfect combustion of natural gas in small area room with a ventilation window near the exhaust port of gas water heated. It shows that the scene of combustion exhaust gas poisoning should be more concerned in the cold season.

OBJECTIVE: To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence. METHODS: The rat heroin dependent model was established by increasing intraperitoneal injection of heroin. DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group. RESULTS: DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time. CONCLUSION Heroin dependence can affect postsynaptic density of hippocampus, amygdala and frontal cortex. The changes become more apparent with extension of heroin dependence time.

Objective To study the effects of pulsed electromagnetic fields(PEMFs)of 15Hz and lmT on osteoblast differentiation of bone marrow mesenchymal stem cells.Methods The bone marrow mesenchymal stem cells were isolated and cultured in vitro,the third passage cells were harvested and half of them was exposed to PEMFs,another half exposed to sham PEMFs served as the control.The activity of ALP was measured.And the ex- pression of osteoblast and adipogenesis was measured with the semi-quantitative RT-PCR,adipogenic differentiation was observed with the Oil Red O Staining.Results When compared with the control,PEMFs of 15 Hz and 1 mT significantly increased the activity of ALP(P

OBJECTIVETo study the effect of CEA gene regulation on the anti-tumor activity of oncolytic adenovirus H101 to esophageal carcinoma, and to explore the intrinsic factors influencing H101 sensitivity.

METHODSStable human esophageal cancer cell line EC9706 cells with lower (EC9706-SCEA) and higher CEA expression (EC9706-CEA) were chosen, thawed and cultured, and then to analyse the influence of CEA expressed at different levels on cell growth. The cytotoxic effect of H101 was assayed by in vitro and nude mouse in vivo.

RESULTSThe cell growth experiment showed that the population doubling time of EC9706-SCEA, EC9706-CEA and EC9706 cells were (30.9 ± 2.0) h, (31.1 ± 2.5) h and (29.1 ± 2.6) h, respectively, showing no significant difference among them (P > 0.05). The cytotoxic activity of H101 was higher on EC9706-SCEA than on other four groups, when MOI was ≥ 0.01 PFU (P < 0.05). The mouse experiment showed that H101 inhibited the growth of transplanted tumors in all experimental groups. Its effect on CEA-silenced tumors (inhibition rate was 61.5% to 74.5%) was significantly higher than that on CEA-overexpression tumors (32.3% to 38.5%) and control EC9706 transplanted tumors (35.5% to 44.8%). There was a significant difference between them (P < 0.05).

CONCLUSIONSThe results in vitro and in vivo experiments show that H101 can enhance the cytotoxic effect on EC9706 cells with lower CEA expression. To silence the expression of CEA may provide a novel strategy for target gene therapy of esophageal carcinoma.

Background About one third of congenital cataract is associated with inheriting factor.The inherited heterogeneity has been found in congenital cataract.To seek the pathogenic gene is essential for the gene therapy. Objective Present study was to map and identify the causal gene for autosomal dominant congenital cataract (ADCC) in a Chinese family. Methods The clinical features of all affected members in this family were examined.Blood samples were collected from eleven family members for genetic linkage analysis.Polymorphic microsatellite markers were selected from the regions which harbor all known loci linked with ADCC.Universal fluorescent-labeled M13 primer was used in linkage analysis.Direct genomic sequencing was used to evaluate the candidate gene for example CRYBB2 gene.This study followed Helsinki Declaration and was proved by Tianjin City Ethic Committee.Written informed consent was obtained from each SUbject before any medical procees. Results The maximum two-point LOD score of 1.20 was obtained for marker D22S315 (θ=0).The LOD score of 0.6 was obtained for marker D16S3068.No mutation in all exons of CRYBB2 gene was found in the family. Conclusion CRYBB2 gene associated with ADCC was excluded from the family.A genome-wide linkage screening should be conducted.Genotyping with microsatellite markers using Universal fluorescent-labeled M13 primer can decrease the cost and obtain the same result.
