Objective To understand the trend of occurrence,diagnosis,and prognosis of breast cancer in the cases treated in Peking Union Medical College Hospital(PUMCH) between 1975 and 2006.Methods A total of 1092 cases of breast cancer treated in the PUMCH from 1975 to 2006 were classified into six groups by time span and reviewed for a comparative study on the parameters of gender,age,menstruation status,tumor size,mumber of positive axillary nodes,pathologic stage,recurrence and metastasis and disease-free survival rate.Results The average age of breast cancer patient has risen from 50.90 to 53.92,while 40-49 year-old group was the largest age group of breast cancer patients,and the percentage of menopause female was the highest.Tumor size has gradually been smaller especially since 2000.The number of positive axillary nodes showed no significant change during the time periods.In all 6 groups,stage-II cases were more frequent,although the percentage of stage-0 and stage-I cases was on the rise,while the percentage of stage-III declined,and that of stage-IV remained stable.In all 6 groups,the 5-year and 10-year disease free survival rate had steadily increased.Conclusions The early diagnostic rate of breast cancer has been improving and subsequently the prognosis has improved as well.

Objective To identify the typical imaging features of steatocystoma multiplex on mammography.Methods Mammographic findings in 9 patients with clinical and pathological diagnosis of steatocystoma multiplex were analyzed along with a review of the current literature.Results Four of the nine patients with steatocystoma multiplex had a positive family history.Nine patients showed multiple,round,thin-walled fatty,radiolucent nodules with well-defined margin.These nodules are located in the superficial layer of the axilla bilaterally.They are also seen on the skin of breast(7 cases),the anterior chest wall (4 cases) and the upper arm (3 cases).Conclusion Recognition of the characteristic mammographic features of Steatocystoma multiplex is important in the management of these patients.

Objective To evaluate the effect of home-based care alongside with health promotion on Wechat towards disabled centenarians, to provide the basis for improving the home and community based care towards the oldest old. Methods A total of 158 indigious centenarians in Hainan were surveyed and 78 of them who were considered disabled by Barthel criteria were selected and then divided into intervention group (with health education on Wechat platform and nursing visit) and control group (with nursing care handbook) by the serial number of them. The living quality,incidence of adverse health events and positive feeling of family care givers of two group were evaluated and compared after 6 months intervention. Results After 6 months of home- care intervention, significant statistical differences in incidence of adverse health events were found between intervention group and control group, which compromise falls (2 cases vs. 13 cases, χ2 = 8.91, P = 0.00), pain (1 case vs. 17 cases, χ2 = 17.28, P =0.00) and constipation (6 cases vs. 15 cases, χ2 = 4.75, P = 0.03). When it came to positive feeling of care givers, the scores of intervention groupwere (33.44±3.72), (36.46±4.06) points, control groupwere (28.10± 3.25), (28.15±3.15) points, significant differences were found at 3rd and 6th month′s follow-up between two groups, which t value represent 4.955 (P=0.00) and 10.142 (P=0.00), respectively. It also suggested that the differences in living quality of the elderly were statistical significant when refered to discomfortble or pain scored 1.58±0.50 and 2.37±0.63 (t=-6.154,P=0.00), and anxiety or depression scored1.73±0.64 and 2.32 ± 0.70 (t=- 3.889,P=0.00). Conclusions Health education on Wechat platform with nursing visit can enhance the effect of home- based care by improving the living quality, incidence of adverse health events of the elderly and positive feeling of family care givers.

Objective To investigate the expression of vascular endothelial growth factor (VEGF) and platelet drived endothelial cell growth factor (PD-ECGF) and their influence on the clinicopathological characteristics and the prognosis in aged patients with gastric carcinoma. Methods The expression of VEGF and PD-ECGF were examined with immnunohistochemical technique through preoperative biopsied specimens in 92 cases.

Objective To investigate the effects of sevoflurane wash-in during cardiopulmonary bypass (CPB) on myocardial injury in patients undergoing coronary artery bypass grafting(CABG).Methods Forty ASA Ⅱ or Ⅲ patients aged 50-64 yr,weighing 53-90 kg undergoing scheduled for CABG under CPB were randomly divided into 2 groups (n =20): control group (group C) and sevoflurane group(group S).Anesthesia was maintained with propofol 3-5 mg·kg-1 ·h-1 and sufentanil 0.5-1.0 μg·kg-1 ·h-1 in both groups.Sevoflurane 1％-2％ was washed into extracorporeal circuit during CPB in group S.Blood samples were taken from central vein after the induction of anesthesia (T0,baseline) and at 6,12 and 24 h (T1-3) after operation for determination of plasma cardiac troponin I(cTnI) concentration and creatine kinase-MB (CK-MB) activity.Myocardial specimens were obtained from right auricle before aortic cross-clamping and at the end of CPB for ultrastructure examination.The severity of mitochondria injury was assessment and scored (0 =normal,4 =impaired inner mitochondrial membrane integrity).Results CPB significantly increased plasma cTnI concentration at T1-3 as compared with the baseline values at T0 before CPB.Plasma cTnI concentration was significantly lower at T2 and T3 in group S than in group C.Mitochondrial injury index was significantly lower at the end of CPB in group S than in group C.There was no significant difference in plasma CK-MB activity between the 2 groups.Conclusion Wash-in of sevoflurane during CPB can attenuate myocardial injury in patients undergoing CABG.

In order to develop potent antidiabetic agents that have inhibitory effect to a-glucosidase, twelve β-acetamido ketone derivatives such as N-{[(substituted-4-oxo-thiochroman-3-yl)phenyl]-methyl}acetamide are designed and synthesized through one-pot Dakin-West reaction. Their chemical structures are confirmed by 1H NMR, 13C NMR, IR and HR-MS. In vitro α-glucosidase inhibition assays of compounds 4a-41 were carried out using glucose oxidase method. The result indicated that most of them possess inhibitory activity in vitro. Compound 4k showed the most potent inhibitory activity with 87.3% inhibition of α-glucosidase at the concentration of 5.39 mmol x L(-1). The structure-activity relationship of these β-acetamido ketone derivatives was discussed preliminarily. Moreover, the molecular docking method was used to study the interaction mode of compound 4k and α-glucosidase. Our results will be helpful for designing of α-glucosidase inhibitors in the future.

AIM: To determine whether the eukaryotic initiation factor-4E (eIF-4E) inhibition facilitates the degradation of heparanase mRNA and alters heparanase protein expression in human colon adenocarcinoma cell line, LS-174T. METHODS: A 20-mer antisense s-oligodeoxynucleotide (asODN) targeted against the translation start site of eIF-4E mRNA were introduced into LS-174T cells by lipid-mediated DNA-transfection. eIF-4E protein and mRNA levels were detected by Western blot and RT-PCR, respectively. The mRNA levels of heparanase were determined by Northern blot. The alterations of heparanase expression were confirmed by Western blot analysis. RESULTS: The 20-mer asODN against eIF-4E specifically and significantly inhibited eIF-4E protein expression. Following eIF-4E inhibition, a significant reduction of heparanase mRNA was observed on Northern blot, and at the same time, heparanase protein expression significantly decreased as well. CONCLUSIONS: The results indicate that the inhibition of eIF-4E strongly reduces the stability of heparanase mRNA in colon adenocarcinoma cell line, LS-174T and resultes in an apparent reduction in the expression of heparanase protein.
