Objective To analyze the clinical data of 112 patients with adult-measles in the Af- filiated Shanghai Sixth People's Hospital and Third People's Hospital of Shanghai Jiaotong University from January to June in 2005,and to evaluate the epidemiologieal and clinical characteristics of adult- measles.Methods To retrospectively analyze the clinical data of 112 patients with adult-measles. Results Totally,112 measles patients were involved in this study,with male 63 and female 49 re- spectively.The gender rate was 1.3:1,average age about 32 years and the proportion of non-resi- dents was 40.18%.The peak of the incidence of disease emerged in April and May,and the positive rate of measle virus IgM antibody in serum was 96.43%.There were 97 patients(86.61%)who had the fever that beyond 39℃and 36 patients(32.14%)who had measle caused viral hepatitis.Conclu- sions There is a trend that the ages of patients that suffered from measle were postponed and the in cidences of disease are increased year by year,which maybe related to the nonstandard inoculation of measle vaccine,or the decrease of IgM antibody levels and so on.Meanwhile,serious toxemie symp- toms and liver damage can be observed.

Objective Analysis of the etiological factors and the diagnostic methods of fever of unknown origin(FUO)in order to avoid misdiagnosis and missed diagnosis.Methods One hundred and twenty-eight patients with FUO were collected from our hospital.Results A final diagnosis was established in 118(92.2%)patients by using serological methods,bacteriological methods,body fluid test,bone marrow examination,tissue biopsy and diagnositic therapy.Infection(62.5%),connective tissue diseases(16.1%),malignancies(11.0%)were found to be the common causes of the fever in these patients while infection was the main cause of FUO in our research.The major pathogens responsible for the infec tion was bacteria,followed by virus and tuberculosis.Adult Still's disease was the most common connective tissue diseases in these patients.Lymphoma,malignant histocytosis and leukemia were the main forms of malignancy.Conclusion Infectious diseases was the most common cause of FUO while connective tissue disease and malignant tumors are also important in the pathogenesis of FUO.

Objective To investigate the influence of iodine excess on expression of TRAIl/TRAIL-sR1 in NOD and Balb/c mice and to study the effect of TRAIl/TRAIL-sR1 on the pathogenesis of experimental autoimmune thyroiditis(EAT). Methods Both Balb/c and NOD mice were divided randomly into control and iodine excess group by feeding with water containing no NaI or 0.05% Nal. The mice were sacrificed after 8 weeks. TRAIL and TRAIL-sR1 mRNA levels were detected by RT-PCR. The function, morphology and apoptosis of thyroids were also observed by ELISA and Tunnel stain. Results Treated by HI, enlarged follicles and flattened epithelium by accumulation of colloid were found in thyroids of both NOD and Balb/c mice. But significant lymphoid cell infiltration and local fibrosis were only found in thyroids of NOD HI group. The relative weight of thyroids of NOD mice in HI group[(104.8±14.5)mg/kg]was heavier than that of control group [(71.8±20.4)mg/kg]. The level of TT4 declined in HI group[(30.77±3.59)mmol/L]compared with control group[(36.43±2.66)mmol/L], meanwhile, the level of TSH was higher in HI group[(6.98±0.66)μg/L]than that in control group [(5.55±0.56)μg/L]. The difference being statistically significant(t=7.773,-9.526,-4.458, all P < 0.05). The relative weight of thyroids of Balb/c mice of HI group[(155.8±20.8)mg/kg]also heavier than that of control group [(105.1±22.0) mg/kg]. The level of TT4 droped in HI group [(19.75±3.32) mmoL/L]was higher than that in control group[(23.46±6.21)mmoL/L], the level of TSH in HI group[(4.14±1.71)μg/L]was higher than that in control group[(3.55±1.41)μg/L], the difference being statistically significant(t=7.554,-7.239,3.140, all P< 0.05). A great deal of apoptotie ceils observed in NOD (3.97±0.91) and Balb/c mice (1.05±0.45) by Tunnel stain were greater than control groups (0.21±0.15, 0.10±0.03), the difference being statistically significant in beth of the two species(t=-7.167,-17.772, both P < 0.05). The apoptosis index of thyroid follicular epithelium in NOD was obviously higher than Balb/c(t=-7.625, P<0.05). The level of TRAIL mRNA did not remarkably change in Balb/c between control group(0.000 59±0.000 39) and HI group(0.001 24±0.000 46, t=-1.940, P>0.05), but it increased apparently in NOD mice HI group(0.018 88±0.005 77) than that of control group(0.009 61± 0.00591, t=-2.71, P<0.05). The level of the expression of TRAIL-sR1 mRNA increased in HI groups of NOD (0.000 53±0.000 15) and Balb/c mice(0.000 42±0.000 09) than that in control groups of NOD(0.000 28± 0.000 05) and Balb/c mice (0.000 17±0.000 06) and the differences were statistically significant between the two species(t=3.050,3.990, all P<0.05). The differences of the expression of TRAIL and TRAIL-sR1 mRNA between the two species were significant(t=-3.37,-4.76, all P<0.05). Conclusions Iodine excess induces colloid goiter in beth species of mice and thyroiditis in NOD mice. The increase of TRAIL and TRAIL-sR1 influenced by iodine excess is one of the molecular bases of follicular epithelium apoptosis and inflammation in thyroids. Genetic factor is a key factor in the pathogenesis of thyroiditis.

OBJECTIVESTo investigate the impact of previous abdominal operations on the outcome of laparoscopic colorectal cancer surgery and to evaluate the feasibility and safety of laparoscopic reoperation in treatment for colorectal cancer.

METHODSAccording to the statistical standards, 653 consecutive patients treated from March 2002 and March 2009 were enrolled in this study. The patients were divided into three groups: upper abdominal surgery group (n = 48), middle-lower abdominal surgery group (n = 110) and non-previous abdominal surgery group (n = 495). Demographic, pathoanatomical and surgical data were compared among the three groups.

RESULTSThere was no significant differences in demographic, pathoanatomical data and post-operative complications among the three groups. Compared with the other two groups, middle-lower abdominal surgery subgroup had a higher intra-operative conversion rate due to intra-abdominal adhesion (4.2%, 11.8% and 3.8% in upper abdominal surgery group, middle-lower abdominal surgery group and non-previous abdominal surgery group, respectively). And no significant differences was found in operating time [(132 ± 36), (141 ± 42), (132 ± 36) min], intra-operation blood loss [(58 ± 50), (81 ± 99), (57 ± 57) ml], blood transfusion rate (6.3%, 10.9%, 7.9%), low sphincter-preserving surgery rate (47.1%, 44.7%, 55.2%), time of first flatus passage [(2.5 ± 1.4), (2.9 +/- 1.7), (2.5 ± 2.1) d], fasting time [(5 ± 4), (5 ± 4), (4 ± 3) d], hospital stay [(17 ± 9), (15 ± 8), (16 ± 10) d] between the three groups.

CONCLUSIONSThe history of previous abdominal operations should not be regarded as a contraindication for laparoscopic colorectal cancer reoperation. The laparoscopic reoperation for colorectal cancer is safe and feasible.

OBJECTIVETo explore the role of Notch signaling in human breast cancers, the expression of Notch1 and its ligand JAG1 in human breast cancers and their relationships with clinical stages of breast cancers were analyzed.

METHODSRT-PCR was used to detect the expression of Notch1 and JAG1 in 62 breast cancer specimens and 22 normal breast tissues at the margin of tumor sections, and the statistical difference of expression rates and standardized coefficient between the two groups were analyzed. To compare the expression intensity of Notch1 and JAG1 at different development stages of the illness and at different stages with or without axillary node metastasis.

RESULTSThe expression rate and standardized coefficient of Notch1 in human breast cancers were significantly higher than those of normal breast tissues at the margin of tumor sections. The expression rate of JAG1 in human breast cancers was 15%, while JAG1 was not detected in normal breast tissues at the margin of tumor sections. The standardized coefficient of Notch1 in cases with axillary node metastasis was significantly higher than that in cases without axillary node metastasis. The standardized coefficient of Notch1 at stage I was significantly lower than that at stage II, and stage II was significantly higher than stage III. There was no statistically significant difference between stage I and stage III.

CONCLUSIONNotch1 and JAG1 are highly expressed in human breast cancers, indicating that the aberrant expression and activation of Notch1 may be related with tumorigenesis of human breast cancer. Notch1 may play different roles at different developmentl stages of human breast cancer.

OBJECTIVETo investigate the value of the HCT-CI score in chemotherapy risk assessment and prognosis of elderly patients with acute myeloid leukemia (AML).

METHODSThe clinical data of 116 AML patients older than 60 years in the department of Hematology, Henan Provincial People's Hospital from January 2000 to December 2010 were analyzed retrospectively. All patients received cytarabine-based regimens, including protocol DA, MA, IA, AA or CAG, followed by cytarabine-based postremission treatment. (1) Comorbidities were evaluated by using HCT-CI score, the early death rates and median survival time were compared among these different groups. (2) These prognostic factors were analyzed by univariate and multivariate analyses.

RESULTS(1) All 116 cases were followed-up. The patient cohort was divided into those with HCT-CI scores of 0, 1 or 2, or ≥ 3. Early death rates were 3.7%, 12.1% and 23.21% in above three groups, respectively (P < 0.01). Overall survival were 345, 225 and 113 days, respectively (P < 0.01). (2) HCT-CI score ≥ 3 (P < 0.01), antecedent MDS history (P = 0.035), high-risk karyotype (P = 0.018), white blood cells at diagnosis ≥ 100×10(9)/L (P = 0.041) were independent adverse prognostic factors with multivariate analysis.

CONCLUSION(1) The HCT-CI score can objectively assess elderly AML patients with comorbidities and predict chemotherapy risk in older patients receiving AML induction therapy. (2) Antecedent MDS history, high-risk karyotype, high white blood cell, and HCT-CI score ≥ 3 are independent adverse prognostic factors of elderly AML patients.
