The enriched soybean high branched chain amino acid mixture (II) was a special hydrolytic soybean protein enriched with a small amount of individual amino acids. The content of its essential amino acids was 68.89% and branched chain amino acids 42.85%.The results of this experiment show that the mixture (II) can improve negative nitrogen balance and elevate the level of serum albumin, and is a good nitrogen source for elemental diet after trauma.

ObjectiveTo investigate the expression of a disintegrin-like and metalloproteinase 8 ( ADAM8 ) in breast cancer and in normal breast tissues and its negative regulation role in tumorigenesis and progress of breast cancer.MethodsThe expression of ADAM8 in breast cancer and normal breast tissues was detected by immunohistochemistry (IHC),qRT-PCR,and Western blot.The relation between ADAM8 expression and the clinicopathological parameters of breast cancer patients was analyzed.ResultsADAM8 was expressed in breast cancer and normal breast tissues.The expression of ADAM8 mRNA and protein was significantly lower in breast cancer than in normal breast tissues (qRT-PCR:P =0.015,IHC:P =0.044,Western blot:P =0.000).The expression rate of ADAM8 was related to lymph node metastasis,tumor stage and tumor size,although the difference had no statistical significance.IHC results showed that ADAM8 expression level was lower in stage Ⅲ + Ⅳthan in stage Ⅰ + Ⅱ ( P =0.574 ).qRT-PCR showed ADAM8 mRNA expression was lower in stage Ⅱb + Ⅲ than in stage Ⅰ + Ⅱ a ( P =0.247).ADAM8 expression was lower in the breast cancer tissues with lymph node metastasis than in those without lymph node metastasis (P =0.560 by IHC and P =0.592 by qRT-PCR).ADAM8 expression was lower in tumors whose size ＞ 2 cm than in tumors whose size ≤ 2 cm,however,the difference had no statistical significance ( P ＞ 0.05 ).ConclusionsADAM8 is significantly lower-expressed in breast cancer than in normal breast tissues,which is associated with clinical stages and lymph node metastasis.The reduced expression of ADAM8 may play a role in the pathogenesis and progress of breast cancer.

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 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 develop an Emotional Intelligence Scale for Chinese pupils.Methods:Data were collected from a sample of 288 primary school students tested by the Emotional Intelligence Scale.Results:①Item analysis showed that the Emotional Intelligence Scale had satisfactory item discrimination.② The Emotional Intelligence Scale had a satisfactory reliability with a 0.90 test-retest reliability and the Cronbach's ? was 0.89.③The result of EFA had five factors,and the range of factor loading was between 0.40 and 0.77.The final revised questionnaire included 25 items,explaining 54.33% of the total variances.④The result of independent-sample t test showed significant gender differences in emotional intelligence.Conclusion:The Emotional Intelligence Scale for pupils has ideal reliability and validity.

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 explore the role of medical insurance in the treatment of the coronary heart disease(CHD) out-patients with or without medicare. Methods 92 CHD out-patients from the medicare department and 92 CHD out-patients from general department of Shandong Taishan Chronic Disease Hospital were investigated and comparatively analyzed on their clinical data in the past 1 year,including the times of hospital visiting,compliance with doctor's instruction,blood pressure,serum lipids and blood glucose control and evaluation of treatment effect based on their clinical symptoms and ECG records.Results The compliance with doctor's instruction,blood lipids,blood pressure control of out-patients in medicare department were significantly better than those in general department(P

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.
