OBJECTIVETo explore the feasibility of IGF2 imprinting system in target gene therapy for tumors.

METHODSThe mouse H19 enhancer, DMD and promoter H19 were amplified by PCR from mouse genomic DNA and then cloned into the plasmid pDC312. The EGFP and DT-A fragments were amplified by PCR and cloned into the recombinant plasmid, and then the shuttle plasmid were transfected into HEK293 cells together with the adenoviral vector Ad5, namely, Ad-EGFP and Ad-DT-A. Adenovirus hexon gene expression was applied to confirm the presence of adenovirus infections. The effect of the IGF2 imprinting system was tested by fluorescence microscopy. RT-PCR and Western blotting after transfection of the recombinant adenoviral vectors into cancer cells were used to show loss of IGF2 imprinting (LOI) and maintenance of IGF2 imprinting (MOI), respectively. The anti-tumor effect was assessed by MTT and flow cytometry after the HCT-8 (LOI). Human breast cancer cell line MCF-7 (MOI) and human normal gastric epithelial GES-1 (MOI) cell line were transfected with Ad-DT-A in vitro. The anti-tumor effect was detected by injecting the Ad-DT-A in nude mice carrying HCT-8 tumors.

RESULTSThe expression of EGFP protein, DT-A mRNA and DT-A protein were seen to be positive only in the HCT-8 tumor cell line. Infection with Ad-DT-A resulted in obviously growth inhibition in HCT-8 cells (75.4 ± 6.4)% compared with that in the control group, and increased the percentage of apoptosis in the HCT-8 cells (20.8 ± 5.9)%. The anti-tumor effect was further confirmed by injecting the recombinant adenoviruses in HCT-8 tumor-bearing nude mice, and the results showed that the Ad-DT-A inhibited the tumor growth, with on inhibition rate of 36.4%.

CONCLUSIONSThe recombinant adenoviruses carrying IGF2 imprinting system and DT-A gene have been successfully constructed, while Ad-DT-A can effectively kill the tumor cells showing loss of IGF2 imprinting. It might play an important role in future target gene therapy against malignant tumors based on loss of IGF2 imprinting.

OBJECTIVETo summarize clinical and molecular features of two children with autosomal recessive chronic granulomatous disease caused by CYBA mutations.

METHODThe clinical records and CYBA mutations were reviewed for analysis of infections and inflammatory complications.

RESULTThe first case was a girl diagnosed with "liver and spleen abscess" in our hospital when she was 2.9 years old, with past history of neonatal impetigo and recurrent purulent lymphadenitis and positive family history. The results of DHR123 flow-cytometry showed that positive phagocytes after phorbol ester (PMA) stimulation was 84.63%. CYBA mutation analysis showed that she had heterozygous 35C > T, Q3X and IVS-2A > G. The second case was a boy diagnosed with "sepsis (salmonella D)" when he was 4 years old with a past history of impetigo, sepsis, perianal abscess, skin infection and positive family history. The results of flow cytometry showed that positive phagocytes after PMA stimulation was 96.13%. CYBA mutation analysis showed that he had homozygous 35C > T, Q3X and his parents were all carriers. All of them had BCG related axillary lymphnode calcification.

CONCLUSIONA22CGD cases had recurrent purulent infections (skin, lymphnode, liver and spleen, lung, blood), DHR123 flow cytometric analysis helped the diagnosis of CGD, CYBA mutation analysis ascertained the diagnosis of A22CGD.

OBJECTIVE To investigate the characteristics of hypopharyngeal carcinoma detected by narrow band imaging(NBI)endoscopy and evaluate the value of NBI in the early diagnosis of hypopharyngeal carcinoma. METHODS Between December 2008 and July 2009,a total of 46 consecutive patients with hypopharyngeal squamous cell carcinoma were enrolled in this study. High performance endoscopic system equipped with the white light mode and NBI mode was introduced in the examination of pharynx and larynx. The quality of visualization of morphologies of epithelial capillary and demarcation line of each lesion under NBI view was evaluated in comparison with conventional white light endoscopy. RESULTS Among the 46 patients,a total of 86 lesions were detected. The notable characteristic of hypopharyngeal squamous cell carcinoma is the well demarcated brownish area and scattered brown dots. The NBI laryngoscope could provide better visualization of morphologies of epithelial capillary and demarcation line in superficial carcinoma of hypopharynx than the white light mode(P

OBJECTIVETo investigate the effects of the epidermal growth factor on the mRNA expression of endothelin-1 and its receptors (ET(A)R, ET(B)R) in hormone refractory prostate cancer (HRPC) PC-3 cell lines.

METHODSPC-3 cells were cultured in vitro. After the treatment with EGF, the mRNA expressions of endothelin-1, ET(A)R and ET(B)R were detected by RT-PCR in PC-3 cell lines. The levels of the mRNA expression of endothelin-1 and its receptors were examined at different time points by RT-PCR.

RESULTSThe expressions of endothelin-1 and ET(A)R mRNA but not the mRNA expression of ET(B)R was observed in PC-3 cell lines. After 24 hours of treatment with EGF, the expressions of endothelin-1 and ET(A)R in PC-3 cell lines were both up-regulated and there was significant difference (P < 0.05) between the experimental and control groups. Different expression levels of endothelin-1 and ET(A)R mRNA were noted at different time points of EGF intervention, up-regulated with the increase of treatment time, and with significant difference (P < 0.05).

CONCLUSIONEGF can up-regulate the mRNA expressions of endothelin-1 and ET(A)R in PC-3 cell lines and play a great role in prostate cancer progression, which may offer a substructure of molecular biology for the treatment of HRPC.

OBJECTIVETo investigate the availability of serum level of macrophage clony stimulating factor (M-CSF) as a marker for early diagnosis of Alzheimer's disease (AD).

METHODSThe serum levels of M-CSF in 70 patients with AD, 52 healthy controls, 22 patients with VAD (vascular dementia) were measured and the serum levels of IL-1 beta, IL-6, TNF-alpha in 32 patients with AD and 20 controls were measured as well.

RESULTSSerum levels of M-CSF were significantly elevated in patients with AD when compared with healthy controls (P < 0.01) and VAD controls (P < 0.05) respectively. At the early stage of mild dementia and middle dementia, serum levels of M-CSF were significantly elevated, but at the later stage of severe dementia, they returned to normal level. Serum levels of IL-1 beta were significantly elevated in AD patients compared with controls (P < 0.05), and serum levels of TNF-alpha and IL-6 were within the normal range in patients with AD.

CONCLUSIONSThe results suggest that serum M-CSF level may provide a convenient and sensitive means for the early diagnosis of Alzheimer's disease.

Objective To estimate the intangible cost and associated factors on patients with hepatitis B-related diseases, so as to explore the differences of the three elicitation techniques on the health economics-related information by trained investigators, using a structured questionnaire. WTP was employed to estimate the intangible cost while an open-ended question format, together with iterative bidding game and payment card were respectively used to elicit WTP for the hypothetical cure of hepatitis B-related diseases. A Multiple linear stepwise regression model was determined to identify those factors potentially affecting the intangible cost. Results A total of 564 subjects from 641 patients with hepatitis B-related diseases were identified for the inclusion of this study. The average annual intangible cost of patient with hepatitis B-related diseases was 54 320.4 Yuan (Ren Minbi).The intangible cost accounted for 53.0% of the total cost, which was much more than the proportions of the direct and indirect costs (38.5% and 8.5%, respectively). Among annual personal and the household income of the patient, proportions of intangible cost were 262.6% and 67.6% respectively,suggesting that the patients were under huge spiritual and psychological pressure. Response rate of the approach, combined open-ended questions with iterative bidding game, was the highest (76.6%) among the three elicitation formats. Considered the characteristics of data being gathered, the approach seemed to be more reasonable. Further studies were needed to examine the results yielded from other WTP elicitation formats. We also noticed that the progression of disease was associated with the increase of direct and indirect costs, but not with the intangible cost. Data from the multiple linear stepwise regression analysis indicated that the types of hospital and commercial medical insurance were significantly different in explaining the variation of the intangible cost. Conclusion Measures should be taken to reduce the intangible cost of hepatitis B-related diseases. The approach regarding the combination of open-ended questions with iterative bidding game should be recommended when carrying our further WTP studies of this kind.

OBJECTIVETo analyze the correlation between pressure-derived collateral coronary flow (PDCF) and Rentrop grade of patients with acute myocardial infarction (AMI).

METHODSPDCF, determined by the ratio of P(w)/P(a), was measured in 29 patients with AMI of the first onset who received primary percutaneous coronary intervention (PCI) within 12 h after the onset. Sufficient collateral flow (group A, n=19) was defined as PDCF>0.24 and insufficient collateral flow (group B, n=10) as PDCF< or =0.24. Rentrop grade of the collateral flow was evaluated by coronary angiography. Echocardiography was performed on the 3rd and 30th day after PCI. The left ventricular ejection fraction, end-systolic and end-diastolic volumes, and the related indexes were obtained.

RESULTRentrop grade was significantly related to PDCF (r=0.75, P<0.01), but a wide range of PDCF was observed in patients with Rentrop grade< or =1.

CONCLUSIONPDCF measurement allows quantitative evaluation of the collateral flow in patients with AMI.
