Objective To estimate prenatal diagnoses strategy with abnormal results of non-invasive prenatal testing (NIPT) based on a case of mosaic for trisomy 22.Methods The pregnanct woman was recruited from Department of Prenatal Diagnosis Center of Xinhua Hospital.Ultrasound scans suggested fetal nuchal translucency was 3.5 mm.Peripheral venous blood was drawn from the pregnant woman for NIPT at 12+2 weeks gestation.For further prenatal diagnosis, amniocentesis was conducted at 16+2 weeks gestation, and karyotype analysis combination with chromosome microarray analysis (CMA) was executed to analysis amniocytes.Results NIPT results suggested that chromosome 21, 18 and 13 were normal and supplementary reports suggested that chromosome 22 were slightly above the normal range.Karyotype analyzed 35 cultured cells.Each of them revealed a normal female karyotype.However, CMA results suggested that chromosome 22 gain mosaic and its copy number was 2.26.The fetus was diagnosed as high possibility of mosaic for trisomy 22.Conclusions Combined with the NIPT results, which was slightly gain mosaic of chromosome 22, a prenatal diagnosis strategy were proposed.When NIPT results suggest chromosomal abnormities, karyotype analysis combination with CMA to diagnose were recommended.

OBJECTIVETo observe the efficacy and safety of modified Shengma Biejia Decoction (MSBD) combined with CAG program in treating elderly acute myeloid leukemia (AML) patients with yin deficiency toxin stasis syndrome (YDTSS).

METHODSTotally 46 elderly AML patients were assigned to the treatment group (24 cases; treated with MSBD + CAG) and the control group (22 cases; treated with CAG + placebos of Chinese medicine) according to random digit table. The therapeutic course of CM placebo or MSBD was 21 days. The clinical efficacy and adverse reactions were observed. Meanwhile, physical state (ECOG Score), transfusion dependency, and TCM syndrome score were compared before and after treatment.

RESULTS(1) The complete remission rate was 54% (13/24) and the objective response rate (ORR) was 71% (17/24) in the treatment group, obviously higher than those of the control group [36% (8/22); 54% (13/24)], with statistical difference (P = 0.036, 0.042). When comparing the efficacy based on risk level, the moderate and poor ORR was 71% (10/14) and 67% (6/9) in the treatment group, and 57% (8/14) and 33% (2/6) in the control group, with statistical difference between the two groups (P = 0.048; P = 0.010). (2) Compared with before treatment in the same group, the ECOG score significantly decreased, the average infusion time of red cells and platelets were markedly prolonged in the treatment group after treatment (P < 0.05). ECOG score, the average infusion time of red cells and platelets were significantly better in the treatment group than in the control group after treatment (P < 0.05). (3) Compared with before treatment in the same group, scores of fever, hemorrhage, and bone pain were markedly reduced in the control group (P < 0.05); scores of fever, fatigue, hemorrhage, dry mouth, and bone pain were markedly reduced in the treatment group (P < 0.05). Better effect in relief of fever, fatigue, hemorrhage, dry mouth, and so on was obtained in the treatment group than in the control group (P < 0.05). (4) In aspect of hematotoxicity, the incidence of neutropenia, anemia, thrombocytopenia was obviously lower in the treatment group than in the control group [29.2% (7/24) vs 54.5% (12/22); 16.7% (4/ 24) vs 45.5% (10/22); 33.3% (8/24) vs 63.6% (14/22); P < 0.05]. The incidence of fatigue and anorexia was obviously lower in the treatment group than in the control group [37.5% (9/24) vs 63.6% (14/22), 37.5% (9/24) vs 81.8% (18/22); P < 0.05].

CONCLUSIONMSBD combined with CAG program in treating elderly AML patients with YDTSS, with efficacy enhancing toxicity reducing effect, had distinct advantages in improving physical condition and clinical symptoms, and reducing transfusion dependency.

Objective To observe the clinical effect of therapy of strengthening Qi, resolving phlegm and dissipating mass for middle-late non-small cell lung cancer. Methods Sixty patients with middle-late non-small cell lung cancer were randomly divided into 3 groups according to the results of intention-to-treat and genetic test. All of the 3 groups were given fundamental supportive and asymptomatic treatment, and additionally Group Ⅰ was mainly given oral use of Jinfuan Decoction with the actions of strengthening Qi, resolving phlegm and dissipating mass based on syndrome differentiation, group Ⅱ was treated with molecular targeted therapy with Gefitinib Tablets and /or Erlotinib Hydrochloride Tablets, and groupⅢ was only given the fundamental supportive and asymptomatic treatment. The 3 groups were treated for 3 cycles(84 days), and then we compared the tumor size, clinical symptoms, quality of life, distant metastasis, and the toxic and adverse effect in each group. Results (1) GroupⅠand group Ⅱhad stronger effect on relieving cough, shortness of breath and lassitude than groupⅢ(P<0.05); groupⅡand groupⅢwere more effective on relieving bloody sputum and chest pain than groupⅠ(P<0.05); groupⅠand groupⅢwere more effective on relieving fever than groupⅡ(P < 0.05). (2) In aspect of quality of life, KPS scores of groupⅠand group Ⅱwere much increased after treatment (P < 0.05), but the scores of group Ⅲ showed no obvious increase (P > 0.05). The improvement of KPS scores in groupⅠand groupⅡwas superior to that in groupⅢ(P<0.05). (3) GroupⅡhad a higher effective rate on stabilizing tumor size, the rate arrived to 65.0％, and was superior to that in groupⅠand groupⅢ(P <0.05) , and the effective rate in group Ⅰ was superior to that in group Ⅲ(P < 0.05). Group Ⅰ and group Ⅱhad a higher stabilizing rate than group Ⅲ(P < 0.05) , but the difference between group Ⅰ and group Ⅱ was insignificant (P>0.05). (4) GroupⅠhad less adverse reaction and higher safety. (5) The distant metastasis rate in groupⅠand groupⅡwas obviously lower than that in groupⅢ(P<0.05), but the difference of distant metastasis rate beetween group Ⅰ and group Ⅱ was insignificant (P > 0.05). Conclusion Therapy of strengthening Qi , resolving phlegm and dissipating mass is effective on relieving tumor-related symptoms , improving the quality of life, stabilizing the tumor, and controlling the distant metastasis in middle-late non-small cell lung cancer patients.

BACKGROUNDIn-stent restenosis is a common complication after stent implantation. However, the assessment of stent lumen in computed tomography (CT) coronary angiography is limited by multiple factors. Our study aimed to evaluate the accuracy and the suspected affecting factors in diagnosing coronary in-stent restenosis by dual-source CT (DSCT) compared with coronary angiography.

METHODSOne hundred and fifteen stents in 50 patients were evaluated with DSCT before coronary angiography for the detection of coronary in-stent restenosis (≥ 50% luminal narrowing). Patency of each stent was analyzed by two independent expert radiologists blinded to the results of coronary angiography. The relationship between diagnostic accuracy and the suspected factors including age, body mass index (BMI), heart rate, variation of heart rate, radiation dose, image quality, location and stent characteristics (type, material, diameter, length and strut thickness) was assessed with both univariate and multivariate analysis. The fitting of a Logistic regression model was evaluated using a receiver operating characteristic (ROC) curve.

RESULTSMean stent diameter was (2.9 ± 0.4) mm. Sensitivity, specificity, positive and negative predictive values and accuracy of DSCT in detection of in-stent restenosis were 69.2%, 91.2%, 50.0%, 95.9%, and 88.7%, respectively. In a subgroup of stents with a diameter ≥ 3.0 mm, sensitivity, specificity, positive and negative predictive values and accuracy were 100.0%, 96.5%, 75.0%, 100.0%, and 96.8%, respectively. Stent diameter < 3.0 mm and poor image quality were associated with poor diagnostic accuracy (P < 0.05). The area under curve of ROC was 0.79.

CONCLUSIONDSCT can provide high accuracy for the assessment of in-stent restenosis in stents with a diameter = 3.0 mm, and can play an important role in ruling out in-stent restenosis.

Objective To observe the effects of cell cycle inhibitor on astrocytic proliferation and scar formation and to study neuronal apoptosis after focal cerebral ischemia in rats.Methods Ischemic model was established by photochemistry method.T_2-weighted MRI was performed on the 3rd, 7th, and 30th day after focal cerebral ischemia.The expression of glial fibrillary acidic protein(GFAP)and apoptosis was observed by immunofluorescence.The protein levels of GFAP and proliferation cell nuclear antigen (PCNA), CyelinA and CyclinB1 were measured by Western blotting from the ischemic and sham animals finished on the 3rd, 7th, and 30th day.Results A marked and significant reduction of brain infarction volume was found in Olomoucine-treated ischemic animals(2.27%?0.28% , 1.87%?0.19%, 1.08%? 0.18%)as compared with controls(5.10%?0.35%, 4.60%?0.26%, 3.96%?0.28%, P

OBJECTIVETo prepare polyelectrolyte multilayer film-coated microbubble ultrasound contrast agent (UCA) and evaluate its effects in contrast imaging on normal rabbit's liver parenchyma.

METHODSPerfluorocarbon (PFC) -containing microbubble UCA (ST68-PFC) were prepared by sonication-based on surfactants (Span 60 and Tween 80). Subsequently, the resulting ST68-PFC microbubbles were coated using oppositely charged polylysine (PLL) and alginate (Alg) by microbubble-templated layer-by-layer self-assembly technique via electrostatic interaction. The enhancement effects in contrast imaging on normal rabbit's liver parenchyma were assessed.

RESULTSThe obtained microbubble UCA exhibited a narrow size distribution. The polyelectrolytes were successfully assembled onto the surface of ST68-PFC microbubbles. In vivo experiment showed that polyelectrolyte multilayer film-coated UCA effectively enhanced the imaging of rabbit's liver parenchyma.

CONCLUSIONSThe novel microbubble UCA obtained via layer-by-layer self-assembly, when enabling more functions, has no obvious difference in enhancement effects compared with the premodified microbubbles. The polymers with chemically active groups (such as amino group and carboxyl group) can be used as the outermost layer for the attachment of targeting ligands to microbubbles, which allows the selective targeting of the microbubbles to desired sites.

BACKGROUNDThe primary reasons for local recurrence and therapeutic failure in the treatment of malignant gliomas are the invasion and interactions of tumor cells with surrounding normal brain cells. However, these tumor cells are hard to be visualized directly in histopathological preparations, or in experimental glioma models. Therefore, we developed an experimental human dual-color in vivo glioma model, which made tracking solitary invasive glioma cells possible, for the purpose of visualizing the interactions between red fluorescence labeled human glioma cells and host brain cells. This may offer references for further studying the roles of tumor microenvironment during glioma tissue remodeling.

METHODSTransgenic female C57BL/6 mice expressing enhanced green fluorescent protein (EGFP) were crossed with male Balb/c nude mice. Then sib mating was allowed to occur continuously in order to establish an inbred nude mice strain with 50% of their offspring that are EGFP positive. Human glioma cell lines U87-MG and SU3 were transfected with red fluorescent protein (RFP) gene, and a rat C6 glioma cell line was stained directly with CM-DiI, to establish three glioma cell lines emitting red fluorescence (SU3-RFP, U87-RFP, and C6-CM-DiI). Red fluorescence tumor cells were inoculated via intra-cerebral injection into caudate nucleus of the EGFP nude mice. Tumor-bearing mice were sacrificed when their clinical symptoms appeared, and the whole brain was harvested and snap frozen for further analysis. Confocal laser scanning microscopy was performed to monitor the mutual interactions between tumor cells and host brain cells.

RESULTSAlmost all the essential tissues of the established EGFP athymic Balb/c nude mice, except hair and erythrocytes, fluoresced green under excitation using a blue light-emitting flashlight with a central peak of 470 nm, approximately 50% of the offsprings were nu/nu EGFP+. SU3-RFP, U87-RFP, and C6-CM-DiI almost 100% expressed red fluorescence under the fluorescence microscope. Under fluorescence microscopic view, RFP+ cells were observed growing wherever they arrived at, locating in the brain parenchyma, ventricles, and para-vascular region. The interactions between the transplanted tumor cells and host adjacent cells could be classified into three types: (1) interweaving; (2) mergence; and (3) fusion. Interweaving was observed in the early stage of tumor remodeling, in which both transplantable tumor cells and host cells were observed scattered in the tumor invading and spreading area without organic connections. Mergence was defined as mutual interactions between tumor cells and host stroma during tumorigenesis. Direct cell fusion between transplantable tumor cells and host cells could be observed occasionally.

CONCLUSIONSThis study showed that self-established EGFP athymic nude mice offered the possibility of visualizing tumorigenesis of human xenograft tumor, and the dual-color xenograft glioma model was of considerable utility in studying the process of tumor remodeling. Based on this platform, mutual interactions between glioma cells and host tissues could be observed directly to further elucidate the development of tumor microenvironment.
