Objective To investigate the clinical effectiveness of coronary artery bypass grafting through descending thoracic aorta in elderly patients with coronary heast disease and to decrease the post-operative complication.Methods Thirteen elderly patients underwent coronary bypass surgery with minimally invasive direct coronary artery bypass (MIDCAB).Age range from 70 to 82 years with a mean of(72.1?6.0)years.Patients suffered from multi vessel disease.Many minimally invasive techniques of“Y”blood vessel graft anastomosis,anastomosis of blood vessel graft to descending aorta,minimally invasive direct,thoracoscope assist were used.Results All patients were survived.The mean duration of intubation was (6.9?0.9) hours.The average ICU stay was (2.5?0.5)days.No patients received blood transfusion.During the short-term follow-up(3 to 14 months) patients had no complaint of angina,Conclusions The technique of“Y”blood vessel graft anastomosis,descending aorta blood vessel graft,minimally invasive direct and thoracoscope assist in combination with coronary artery bypass grafting is a safe and cost-effective new procedure for elderly patients with multi-coronary artery disease.

Medical ethics is correlated with further development of affiliated teaching hospital.Our hospital took ‘ Bethune spirit’ and philosophy of forgiveness and kindheartedness as guidance and became the first batch of Bethune spirit model hospital of Chongqing.Teaching quality was improved by providing lectures about ‘ Bethune spirit’ for medical students and equally emphasizing medical knowledge and medical ethics education.Anti-corruption and academy governing movements with the subject of ‘ Bethune spirit’ were carried out to repel academic misdeed,with the result that clinical,teaching and scientific works were promoted and advanced.

ObjectiveTo observe the inhibition effect of docetaxel-loaded lipid microbubbles (DLLM) combined with ultrasound targeted microbubbles destruction (UTMD) on microvessel in rabbit VX2 liver tumor models.MethodsSixty rabbits were randomly divided into 6 groups (n= 10),i.e.Doc group (used docetaxel only),DLLM group (used docetaxel-loaded lipid microbubbles),Doc+US group (used docetaxel combined with ultrasound positioning irradiation),PLM+US group (used microbubbles combined with ultrasound positioning irradiation),DLLM+US group (used docetaxel-loaded lipid microbubbles combined with ultrasound positioning irradiation) and control group.The expression of CD34 and VEGF and microvessel density (MVD) were compared among different groups.ResultsAfter treatment,the expression of CD34 in DLLM+US group was lower,the MVD of DLLM+US group was markedly lower than that of the other groups (P＜0.01),while the expression of VEGF in this group was the lowest among all 6 groups (P＜ 0.01).ConclusionDLLM combined with UTMD can inhibit the generation of microvessels in rabbit VX2 liver tumor,thus inhibit the growth of the tumor.

Objective To describe the skeletal CT imaging manifestations in patients with tuberous sclerosis complex(TSC),and to analyze their diagnostic value so as to establish an adequate skeletal change imaging data for the diagnosis of TSC.Methods Thirteen patients fulfilling TSC diagnostic criteria were examined with CT of the brain (n=13)and abdomen (n=7).Examinations from January,2004 to July, 2006 were retrospectively analyzed.Results There were three forms of lesions being demonstrated on CT: (1)Multiple sclerosing nodule (n=13):numerous,ovoid and circular,homogeneous,small and well- defined loci and symmetrical lesions were revealed in all cases in the central marrow portion of the bones, which could mimic blastic metastases.Follow-up CT imaging showed no change in both size and number. The lesions measured approximately 2-10mm.(2)Local sclerosing bone dysplasia with little bone expansion (n=7).Symmetrical and irregular density in the radix of the posterior arch of the vertebral body (n = 5 ).(3 )The spherical periosteal proliferation demonstrating as a cortex double line sign (n=2 ),and cortical thickening of metatarsals (n = 3 ).The appearance of the skeletal manifestation was as that in adulthood.Conclusion CT imaging of the skeletal system in TSC has some characteristics,by which the diagnosis of TSC could be made if combined with other main clinical diagnostic criteria. We suggest that those particular findings can be added as primary diagnostic features in the clinical diagnosis of TSC.

?AIM:To analyze the clinical features of Terrien marginal degeneration ( TMD) .?METHODS:Fifty-six patients(90 eyes) admitted in our hospital from January 2013 to January 2015 were selected as observation group.At the same period, 56 healthy (88 eyes) for corneal examination were as control group to analyze the clinical features of TMD. With immunohistochemistry and enzyme linked immunoassay method ( ELISA), the levels of HLA-DR, HLA-DQ and tumor necrosis factor-α( TNF-α) in blood samples of TMD patients were tested.?RESULTS:The transparent degree of the eye, lipid deposition in TMD patients with early, advanced, swelling and hole-wearing period were significantly different (χ2=10.85,χ2=65.32, P<0.05).Astigmatism in TMD patients with early and advanced, swelling and hole -wearing period were significantly different (P<0.05).The levels of HLA-DR, HLA-DQ and TNF-αin blood samples between the two groups were significantly different ( t=45.326, t=23.564, t=19.86, P<0.05).?CONCLUSION: Terrien's marginal degenerative is an inflammatory disease characterized by increased levels of TNF-α, HLA-DQ, and HLA-DR in peripheral blood, decreased corneal transparency, astigmatism and lipid deposition.This research provides experiment evidence for the mechanism of TMD.

Iodine, an essential component of the hormones produced by the thyroid gland, is widely but unevenly distributed in the earth's environment. Great difference exists in the iodine nutritional status of populations residing in different region. Both iodine deficiency and iodine excess can injure the thyroid gland. Iodine deficiency tigers endemic goiter, cretinism, and hyperthyroidism, while iodine excess can result in high iodine goiter, chronic lymphocytic thyroiditis, iodine-induced hyperthyroidism, and hypothyroidism; also, iodine deficiency or excess may affect the histological type of thyroid cancer. In 1996, China began to implement the universal salt iodization policy, which has basically eliminated the iodine deficiency disorders nationwide; however, it also caused the changes in the spectra of other thyroid diseases including iodine-induced hyperthyroidism, autoimmune thyroid disease, and papillary thyroid carcinoma. Individualized iodine nutritional status assessment for the populations, particularly those with thyroid diseases, will be beneficial.

OBJECTIVETo investigate the different expressions of cytoskeletal organizer ezrin and cytoskeleton protein beta- and gamma-actin in hepatocellular carcinoma (HCC) cell lines with different metastatic potentials and to explore the role of ezrin in cell growth and metastasis in HCC cell lines SF7721 and MHCC97-H.

METHODSImmunofluorescence, RT-PCR and Western blot were used to detect the gene and protein expressions of ezrin and actin in hepatocellular carcinoma cell lines with different metastatic potentials. RNA interference (RNAi) was applied to down-regulate the ezrin expression in SF7721 and MHCC97-H. Changes of the cell growth and metastasis potentials after the RNAi treatment were studied. MTT assay was used to detect cell proliferation changes and Transwell assay was applied to observe the changes of cell motility and invasiveness.

RESULTSBoth ezrin and cytoskeleton protein were demonstrated in the cytoplasma of the cells at the same time. The expression of them in cell lines with high metastatic potential, such as SF7721, MHCC-1 and MHCC97-H was obviously higher than in those with low metastatic potentials, such as SMMC-7721, Hep3B and HepG2 (chi2= 13.277, P = 0.010; chi2= 21.815). The mRNA and ezrin and cytoskeleton protein gamma-actin were over-expressed in HCC cell lines with high metastatic potentials. The expressions of beta-actin of cell lines with different metastatic potentials showed no differences. Ezrin protein was successfully down-regulated and the proliferation and the invasiveness of the cells decreased with low ezrin protein level in SF7721 and MHCC97-H.

CONCLUSIONOver-expression of ezrin and cytoskeleton protein gamma-actin are associated with the process of metastasis of hepatocellular carcinoma cells. The growth and invasiveness of SF7721 and MHCC97-H cells can be inhibited by down-regulating ezrin expression.
