0.05). Integrin ? 5? 1 was significantly over expressed in lymph node metastatic cancer compared with that in corresponding PGC ( t =2.45, P 0.05) and it showed no correlation with integrin ? 5? 1 expression( r = 0.156, P =0.37).Conclusion Over expression of integrin ? 5? 1 is present in GC and associates with the progression of tumor, implying that it may be viewed as the indicator of invasion and metastasis and the candidate target of gene therapy of gastric cancer. However, integrin ? 5? 1 may not play an important role in the vascularization of GC.

Objective To explore the morphological, immunohistochemical characters and prognosis in one case of patients with cutaneous anaplastic large cell lymphoma complicated with acute myeloid leukemia (C-ALCL-AML). Methods The histopathology, immunohistochemical markers and follow-up information of one case of ALCL-AML was analyzed and the correlated literature was reviewed. Results The patient, 69 year-old, female, was initially present with shin lesion on one finger and abnormal myelogram. The histopathology of shin lesion showed that tumor cells were composed of large cells with abundant cytoplasm,the nuclei were large and irregular, and were infiltrated by Neutrophil and eosinophil. The CD30,CD3 and CD43 of tumor cells were positive, but ALK negative by immunohistochemical method. The number of WBC in peripheral blood was 15.5×109/L and 51 archaeocytes were in every 100 karyotes. Bone marrow aspiration detection showed that bone marrow was hyperplasia and the ratio of myeloblast was 78 %. This patient was diagnosed as C-ALCL-AML, partly differentiation type(AML-M2a). Conclusion C-ALCL-AML is very rare. Its diagnosis is dependent on clinical data, histopathology and immunohistochemical markers. The first choice of treatment is chemotherapy, but its prognosis is poor.

Objective To determine whether color doppler ultrasonography (CDU),thyroid function or thyroid autoimmune antibodies could identify Graves' disease in pregnancy(GDP) in pregnant patients with newly diagnosed thyrotoxicosis.Methods It is an observational study.Sixty-eight pregnant patients with newly diagnosed thyrotoxicosis including gestational hyperthyroidism (GHT) subjects (GHT group,n =33) and GDP subjects (GDP group,n =35),and 62 age-and sex-matched healthy subjects (C1 group:pregnant,n =32,C2 group:non-pregnant,n =30) were recruited.Thyroid function,human chorionic gonadotropin(HCG),thyroid autoimmune antibodies were detected.Peak systolic velocity of the superior thyroid artery (STA-PSV) and diastole inner diameter(STA-D) of the superior thyroid artery were measured by CDU.A ROC curve was used to evaluate STA-PSV,STA-D,thyroid function and thyroid autoimmune antibodies for identification of GDP.Results The area under the ROC curve of STA-PSV,STA-D and thyroid stimulating hormone (TSH),free T4 (FT4) for GDP were 0.905,0.887,0.803 and 0.786,respectively.The optimal cut-off points of STA-PSV,STA-D,TSH and FT4 for GDP were 40 cm/s,2.0mm,0.03 mIU/L and 30 pmol/L with the sensitivity of 82.9％,72.1％,81.8％,76.2％ and specificity of 81.8％,87.9％,75.2％,80.3％,respectively.Conclusions Detection of STA-PSV and STA-D by CDU,as well as thyroid function,is useful in screening GDP in pregnant patients with thyrotoxicosis.

Objective:To compare the mental health between the urban mothers and rural mothers of children with cleft lip and pal-ate.Methods:1 68 mothers(including 1 24 rural and 44 urban)of the children with cleft lip and palate were included in the trial group and 82 mothers of normal children were included in the control group.The subjects were tested by the self-assessment symptom lists of SCL-90 for the evaluation and comparison of mental health.Results:The scores of nine dimensions of trial group in somatization, forcing symptoms,depression,anxiety,etc were significantly higher than those of the control group(P <0.05).The scores of nine di-mensions of rural group in somatization,forcing symptoms,depression,anxiety,etc were higher than those of the urban group,the ri-val,psychotic and total scores showed significant differences(P <0.05);Conclusion:The mental health status of mothers of children with cleft lip and palate is poorer than that of those of normal children.That of the rural mothers is poorer than that of the urban ones. Special attention should be paid to the mental health status of the parents of children with cleft lip and palate.

OBJECTIVE:To determine serum concentrations of western medicines in patients treated with "traditional Chinese antiepileptic medicine" alone and to evaluate the curative effects.METHODS:A total of 60 epileptic patients who visited our hospital between Feb.1997 and June 2006 were subjected to plasma drug level monitoring and during which the patients were treated with "traditional Chinese antiepileptic drugs" alone.Plasma concentrations of 4 kinds of western medicin-es were determined by FPIA.RESULTS:Of the 60 cases,valproic acid,carbamazepine,phenytoin and phenobarbitone were detected in 18,40,41,and 47 cases/times,respectively.On average,more than two kinds of western medicines were detected in every patient,and the blood concentrations were mostly beyond effective plasma drug concentration.The total curative effects were unsatisfactory.CONCLUSION:The fact that western medicine ingredients detected in these traditional Chinese antiepileptic medicines is inconformity with medication principle of epilepsy.Traditional Chinese antiepileptic medicines should be used with caution in the clinic in the treatment of epileptic patients.

Objective To summarize and analyze the relationship between exposure to rabies and its prevalence in Jurong City from 2003 to 2007,and discuss further the possible solutions to it.Methods The data of people vaccinated after being biten by animals were collected,manipulatd,and analyzed,with their illness records dealt with accordingly from 2003 to 2007 in Jurong City.Results Not a single one of 21 596 cases was that of rabies with proper treatment in the last 5 years.The sex ratio was 1.47∶1.The highest probability of exposure was the preschoolers under the age of 10.The disease occurred throughout the year,with the peak in July and September.Those biten by dogs accounted for 86.85% of the exposure to rabies,and among them,people biten by domesticated animals were in the majority.Wounds by the domesticated dogs reached 74.60%.Not a single case was treated properly among the 9 rabies cases reported in the same period.Conclusions Strengthening the management of domesticated dogs,publicizing the knowledge of rabies,treating the wound properly and thoroughly,innoculation with vaccine from the very beginning and administering rabies immune globulin are the effective ways to prevent rabies.

Background and purpose:Now 3-dimensional conformal radiotherapy(3DCRT)and intensitymodulated radiotherapy(IMRT)are widely used in the treatment of head and neck tumor.For the parotid,this target area is located on the side of the head and the tumor has a concave shape.What kind of radiation method can be used more eriectively to achieve dose uniformity and protection organs at risk is the topic of much discussion.The postoperative irradiation of parotid tumor is varied in the techniques used.In this study,3-dimensional conformal radiotherapy (3DCRT),intensity-modulated radiotherapy(IMRT)and simplified forward planned multi-segment radiotherapy (MSRT)were compared to conventional planning techniques in order to investigate the potential advantages of these new treatments.Methods:The conventional planning included the large opposed lateral fields with 2 or 3 weight ratio at the target lateral(2F-2D)and the unilateral field with mixture of 6 MV photon and electron beams(X+E).The 3D techniques included 3DCRT,MSRT and IMRT.Their dose distributions were calculated and compared for 8 patients treated in our center.Different beam arrangements were used for 3D techniques.In each case.the dose of PTV was prescribed to 60 Gy.All plans were compared using dose-volume histogram data.The conformity index(CI)and heterogeneity index(HI)of dose were used to evaluate the dose coverage of the target volume.Dose sparing of brain stem.spinal cord and the contra lateral parotid was also compared.To compare IMRT and MS RT,the timing ofplanning and radiation delivery was recorded.Results:Compared to conventional planning,the 3DCRT,MSRT and IMRT plans produced adequate target coverage,and the CI showed 3DCRT plans(0.78)produced poorer target coverage than MSRT(0.81)and IMRT(0.85).MRST and IMRT plans showed a significant reduction in maximum dose to the spinal cord,brainstem and the contra lateral parotid,compared to the conventional plans,while the 3DCRT plan did not show significant sparing of these structures.MSRT and IMRT plans produced better dose coverage among all the techniques.The efficacy of beam delivery comparing between two modulated planning showed MSRT was better.Conclusion:For postoperative irradiation of parotid cancer,3D planning techniques generated better target dose-coverage,without compromising the dose-sparing advantages of important structures.A satisfactory dose distribution can be obtained using MSRT and such a simple technique may be suitable for replacing IMRT.
