Objective To evaluate the short-term efficacy and safety of concurrent chemoradiotherapy (CCRT) with paclitaxel and lobaplatin for advanced esophageal cancer.Methods Sixty-eight patients with advanced esophageal cancer were randomly divided into two groups according to random number table method:CCRT with paclitaxel and lobaplatin (TL group) and CCRT with DDP and 5-Fu (PF group).The CCRT regimen included radiotherapy at a total dose of 60-70 Gy,and concurrent paclitaxel 60 mg/m2 on d1,a fraction per week for 6-8 weeks,lobaplatin 30 mg/m2 on d2,a fraction per 3 weeks (TL group),and concurrent DDP 75 mg/m2 on d1,5-Fu 500 mg/m2,d1-5,CF 200 mg/m2,d1-5 (PF group).Results All 68 patients were evaluable for response.The response rates were 73.53％ in TL group and 50.00％ in PF group,the median progression-free survival were 13.0 months in TL group and 6.5 months in PF group.There were significant differences (x2 =4.023,P =0.040; x2 =4.512,P =0.034).The incidence rates of Ⅲ-ⅣW degree nausea and vomiting,granulocytopenia and thrombocytopenia were 5.88％ and 35.29％,20.59％ and 32.35％,32.35％ and 8.82％,and the differences were statistically significant (x2 ＝ 8.500,P =0.003 ; x2 =3.200,P =0.041; x2 =6.710,P =0.016).The incidence rates of Ⅲ-Ⅳ degree esophagitis in the two groups were 11.76％ and 17.65％,and there was no significant difference (x2 =1.45,P =0.493).Conclusion The efficacy of TL group in the treatment of advanced esophageal cancer is excellent,and all toxicities are well tolerated.So this protocol may be considered a main regimen in the treatment of advanced esophageal cancer.

Objective: To explore the relationship between social support and mental health,and constructing the influential model of social support and personality on mental health.Methods: Both cross-sectional and longitudinal questionnaire surveys were used on 192 university students.Results: Social support and personality had significant effect on mental health.Social support had indirect effect on later mental health via concurrent mental health and later social support,and personality was the modulating variable of social support to mental health.Conclusion: It indicates that social support can effectively predict mental health in 2 years,and it also has indirect effect on mental health via personality.

Background and purpose:Nipple secretion is one of the frequent symptoms in mammary gland disease.Clinically,about 1% breast cancer patients demonstrate with nipple secretion as initial symptom.It could be used as a screening tool for the patients with nipple secretion but no palpated mass and increase the possibility of early diagnosis for breast cancer.In 1997,our country developed a new technique——breast fiberoptic ductoscopy(FDS). It uses a ?(0.7) millimeter optic scope to insert into the nipple discharge canal orifice,and depends on introscope technology to observe and record the normal or abnormal changes in mammary gland ductus.Its advantages are not only in highly diagnostic sensitivity(above 90%),but also in accurate location of tumor,so it can be used to diagnose early breast cancer and mammary gland ductal diseases.This study evaluated the clinical effect of breast FDS in diagnosis and treatment of abnormal nipple secretion.Methods:1 000 patients had been under examination by FDS.Results:Of the 1 000 cases,there were 33 cases((3.3%)) of early breast cancer;412 cases(41.2%) of papilloma and papillomatosis;and 480 cases(48%) of either ductal ectasia and or chronic inflammation.Duct endoscoptic biopsy was successfully performed on 30 cases,220 cases(55%) with chromic inflammation were cured by perfusion.453 cases were received operation.The accordance rate with pathologic eiagnosis was 90.7%.Conclusions:FDS is a very important and new method to diagnose breast.FDS could be inserted into 5th ducta lumen of breast and significantly increase the positive detection of breast cancer.Because the position and nature of the lesions can be determined accurately by FDS,tt is used as intervening treatment for some intraductal papilloma and chronic inflammatory disease.FDS will be of great influence on early diagnoses and treatment of the breast cancer.

Objective: To develop a Constructive Thinking Scale for Chinese pupils. Methods: Data were collected from a sample of 302 primary school pupils tested with the Constructive Thinking Scale. Results: ①Item analysis showed that the Constructive Thinking Scale had satisfactory item discrimination; ②The Constructive Thinking Scale had a satisfactory reliability with a 0.83 test-retest reliability, and the Cronbach’s ? was 0.88; ③The result of EFA had five factors, and the range of factor loading was between 0.36 and 0.75. The final revised questionnaire included 23 items, which could explain 53.13% of the total variances. The scale had an ideal criterion validity. Conclusion: The Constructive Thinking Scale for pupils has ideal reliability and validity, and can be used in assessing Chinese pupils’ constructive thinking .

Objective To study the relationship between the white blood cell (WBC) count of peripheral blood at the early stage of acute myocardial infarction (AMI) and the prognosis.Methods 100 cases of AMI were divided into normal WBC counts and elevated WBC counts group.Clinical characteristics of the two groups were compared.Results The cases of AMI with leukocytosis is apt to complicate left ventricular failure,arrhythmia and excitable hyperglycemia.The peak value of CK and ECG QRS scoring as well as mortality were elevated.Conclusion The WBC has an important prognostic significance in AMI.

Objective:To investigate the changes in protein metabolism after the use of recombinant human growth hormone(rhGH) in gastrointestinal tumor patients after operation.Methods:Thirty-nine patients with gastrointestinal tumor were randomly(double-blind) divided into two groups: ①the control group(n=20),which was treated with hypocaloric parenteral nutrition and placebo,②the rhGH group(n=19),which was treated with hypocaloric parenteral nutrition and rhGH.The levels IGF-1 and protein metabolism were observed.Results:The concentrations of IGF-1,pre-albumin,transferrin and fibronectin were decreased in the two groups on the 3th day after operation.The administration of rhGH resulted to significant increase in serum levels of IGF-1,pre-albumin,transferrin and fibronectin.Conclusion:The administration of recombinant human growth hormone can increase the protein synthesis and improve the nutritional condition.

Objective:To evaluate the effects of different nutritional supports in gastric cancer patients undergoing radical resection.Methods:Sixty patients with gastric cancer were randomly divided into three groups: parenteral nutrition(PN)group,enteral nutrition(EN) group and parenteral nutrition combined with enteral nutrition(PN-EN) group.The rate of complication, recovery time of the gut function,average post-operative hospital stay,changes of liver function,levels of blood glucose,serum albumin,prealbumin and transferrin,levels of nitrogen balance and change of body weight were observed in the three groups.The therapeutic effects of post-operational nutritional support were studied.Results:There are no significant difference in the rate of complication,average post-operative hospital stay,changes of liver function and level of blood glucose.The recovery time of the gut function in EN group was shorter than that in PN and PN-EN groups(P

Syndrome of cachexia,which is a common feature of many types of cancer,characterized by loss of adipose tissue and skeletal muscle,is responsible not only for a poor quality of life and poor response to chemotherapy,but also a decreased survival time.It can not be fully explained by the accompanying anorexia,because increasing nutrient support is unable to reverse the wasting syndrome.Although patients with cachexia frequently show an elevated resting energy expenditure,cachexia can occur with a normal energy expenditure.Lipid mobilizing factor and proteolysis inducing factor,two tumor-derived factors,can directly mobilize fatty acids and amino acids from adipose tissue and skeletal muscle respectively.It is important of the knowledge about the roles and mechanism of LMF and PIF in the development of cancer cachexia,which should lead to the development of new therapeutic methods.
