Sixty patients with malignant stenosis, esophagus and anastomotic stoma fistula were selected from Jiangsu General Hospital of Armed Police Forces between January 1995 and June 2008, including 46 males and 14 females, aged 36-77 years. Following pathologic diagnosis, 50 patients had squamous cell carcinoma, 8 had adenocarcinoma, and 2 had adeno-squamous carcinoma. Of 60 patients, 33 had esophageal carcinoma stenosis and esophagus-gastric cardia carcinoma stenosis, 20 had esophageal carcinoma stenosis combined with fistula, 7 had esophageal-stomach anastomosis combined with thoracic cavity fistula; in addition, there were 22 cases of first onset of fistula and 5 of multiple fistula. All patients were treated by esophagus memory Ni-Ti alloy coated stent implantation. Of 58 patients with successful implantation, 21 developed stent blockage due to dysphagia, and were alleviated after foreign body removal; 3 developed stent dislocation (removal and re-implanted); 7 developed restenosis due to tumor tissue ingrowth 3 months after implantation. Of 5 patients with multiple fistula, 3 were re-implanted to form invagination of 2 stents, which succeeded in blocking the fistula. Of 33 patients with esophageal carcinoma stenosis and esophagus-gastric cardia carcinoma stenosis, 26 underwent radiotherapy with or without chemotherapy (mean survival time: 24 months). Twenty patients with esophageal carcinoma stenosis combined with fistula survived for 6 months averagely. Seven patients with esophageal-stomach anastomosis combined with thoracic cavity fistula survived for 3 months averagely. Of 60 patients, 42 felt retrosternal pain, and 2 patients’ stents were extracted due to severe pain; 20 patients developed esophageal reflux. No bleeding, perforation or septicemia occurred. The results indicate that memory Ni-Ti alloy stent is effective in treating malignant stenosis, esophagus and anastomotic stoma fistula, showing good biocompatibility.

It is a popular practice for Chinas academia to regard SCI(Science Citation Index)and its IF(Impact Factor)as fundamental indexes for research competency evaluatiop.This article however holds that SCI and IF are but quantitative measurements for evaluating periodicals,and whether it is scientific to evaluate research results with such indexes as they are remains to be jusfified.It also suggests that practitioners in research organizations fully comprehend the meaning of SCI and IF,and use them correctly,so as to guide researchers to contribute their works to proper publishers.

Psychological disorder has a high morbidity rate among patients with cardiovascular disease. Patients with cardiovascular disease associated with depression, especially post myocardial infarction and acute coronary syndromes associated with psychological disorder, have not only a poor prognosis, but also a high mortality . Therefore, comprehensive and perfect intervention is extremely important for patients with cardiovascular disease associated with psychological disorder. The intervention for such kind patients needs an integrated disease management. It needs to consolidate the treatment of body's disease to strengthen second-level prevention of heart disease, and pay attention to the intervention for psychological disorder as well.This paper aims to provide reference for reducing the negative effects of psychological illness in patients with cardiovascular disease during clinical treatment process, and make prospects about the significance of double heart medical model, through summarizing the interaction effects of psychological factors on patients with coronary heart disease, the significance ofdouble heartnursing mode and the specific nursing measures.

OBJECTIVE:To observe the short-term efficacy and toxicity reaction of 2 regimens of taxotere combined with epi-rubicin in the neoadjuvant chemotherapy of breast cancer. METHODS:78 patients with locally advanced breast cancer were random-ly divided into TEC group(45 cases)and TE group(33 cases). TEC group was treated with taxotere 75 mg/m2 by intravenous in-jection,d1+epirubicin 60 mg/m2 by intravenous injection,d1+cyclophosphamide 500 mg/m2 by intravenous injection d1. TE group was treated with taxotere 75 mg/m2 by intravenous injection,d1+epirubicin 60 mg/m2 by intravenous injection,d1. 21 days were a treatment course for 2 groups,and there were totally 4-6 courses. In the 2 groups,efficacy and toxicity reaction were evaluated af-ter 4 weeks at least,and survival rate of 6 months was followed-up. RESULTS:The differences were not statistically significant in the short-term efficacy and toxicity reaction and survival rate between 2 groups (P>0.05). CONCLUSIONS:TEC and TC have similar short-term efficacy and safety in the treatment of locally advanced breast cancer. Both of them can be used as adjuvant medi-cines for neoadjuvant chemotherapy.

BACKGROUND: The reaction of osteoblasts is important role in the reconstruction of osteocytes, and the mechanism of bone remodeling can be known from the cytological level through analyzing the mechanical reaction of osteoblasts under different loading.OBJECTIVE: To analyze the effects of low frequency vibration on the proliferation and differentiation as well as the matrix excretion of cultured human osteoblasts.DESIGN: A comparative observation.SETTING: Department of Orthopaedics, Nanfang Hospital of Southern Medical University.MATERIALS: The experiment was carried out in the laboratory of Nanfang Hospital from January to December in 2002. Human osteoblasts were isolated from the iliac cancellous bone of adults.METHODS: The osteoblasts were cultured for 48 hours, and then treated with low frequency vibration of 0.1, 0.2, 0.5, 2 and 5 Hz. The proliferation of the osteoblasts was detected with flow cytometry, and the activity of alkaline phosphatase (ALP) and content of osteocalcin were assayed by spectrophotometric methods and radioimmunoassay respectively.MAIN OUTCOME MEASURES: ① Effects of low frequency vibration on the ALP activity and osteocalcin excretion of osteoblasts; ② Effects of low frequency vibration on the proliferation of osteoblasts detected with flow cytometry.RESULTS: ① 0.2 and 0.5 Hz vibrations could markedly increase the ALP activity of osteoblast (P ＜ 0.01), but that of 5 Hz obviously decreased the ALP activity (P ＜ 0.01). 0.1 and 2 Hz vibrations had no obvious effects on the ALP activity of osteoblasts. ② 0.2 and 0.5 Hz vibration could significantly increase number of osteoblasts at S phase from 10.4% to 12.45% and 16.12%, and the proliferative index increased from 20.14% to 26.21% and 28.75%; 0.1 and 2 Hz vibration has not obvious effects in osteoblast proliferation index; 5 Hz vibration obviously decreased the proliferative index value to 13.22% (P ＜ 0.05). 0.1 and 2 Hz vibrations had no obvious effects on the proliferative index of osteoblasts (P ＞ 0.05). ③ 0.2 and 0.5 Hz vibrations could obviously increase the amount of osteocalcin excretion to 1.87 μg/L and 2.47 μg/L(P ＜ 0.05), but 2 and 5 Hz vibrations decrease the amount of osteocalcin excretion (P ＜ 0.05), and that of 0.1 Hz had no obvious effect on amount of osteocalcin excretion (P ＞ 0.05).CONCLUSION: Low frequency vibrations of 0.2-0.5 Hz could accelerate the proliferation and differentiation as well as the excretions of active materials of osteoblasts, and it plays an instructive role for low frequency vibration to treat fracture.

Prediabetes is an abnormal condition between normal glucose metabolism and diabetes mellitus. Impaired glucose tolerance (IGT) is an indicator of high-risk state of prediabetes. Positive interventions of IGT, including life style changes and pharmacological intervention, can effectively postpone and reduce the development of prediabetes into type 2 diabetes mellitus, suggesting that IGT is a key point of diabetes prevention. Currently, pharmacological intervention for prediabetes is still at early stage. In this review, we summarizes recent clinical and preclinical studies on pharmacological intervention for prediabetes, and studies in the development of animal models with IGT and the application of new techniques. We also discuss the prospects of drugs for diabetes prevention, especially with the traditional Chinese medicine.
