Objective To detect the expression of Id1 and p53 in human breast cancer and study their relationship. Methods To choose 80 cases of breast cancer from the surgical department of Tangshan people's hospital. All patients didn't get radiotherapy and chemotherapy before surgery. The expression of Idl and p53 of breast cancer were studied by using SABC immunohistochemistry. Results The expressions of Id1 were found in cytoplasm, while the expression of p53 was found in cell nucleus. The positive rates of Id1 and p53 were 87.5 %(70/80)and 90.0%(72/80) respectively in breast cancer tissues. The expression of Id1 and p53 were significantly higher in breast cancer tissue than those in adjacent non-tumor breast tissues,benign tumor tissues and normal breast tissues(P ＜0.05). The positive rates and expression intensity of Id1 in breast cancer had significant correlation with lymph node metastasis and pTNM stage of the tumor, but had no significant correlation with age, histological differentiation and tumor size. The positive rates and expression intensity of p53 in breast cancer had significant correlation with lymph node metastasis of the tumor, but had no significant correlation with age, histological differentiation,tumor size and pTNM stage. Conclusion Expression of Id1 in human breast cancer is up-regulated. Its expression is associated with lymph node metastasis and TNM stage and represents an independent marker for prognosis of breast cancer. To reduce the expression of Id1 will become the strategy of curing breast cancer. Expression of Id1 and p53 in human breast cancer have the same clinic significance. Each of them can represent an independent marker for prognosis of breast cancer.

The β-adrenergic receptor has close relationship with the occurrence and development of tumor.The β-adrenergic receptors were expressed in a variety of tumors.Its activation can stimulate tumor growth by promoting cell proliferation,inhibite apoptosis,promote angiogenesis,and enhance tumor invasion and metastasis.The β-adrenergic receptor blockers can suppress the tumor growth,which may become one of the effective methods of cancer prevention and treatment.

Objective To investigate the effectiveness of intensive sit-to-stand training in improving the balance and walking of hemiplegic stroke patients. Methods Sixty hemiplegic stroke patients were randomly divided into an observation group and a control group with 30 cases in each.Both groups were treated with routine rehabilitation.The observation group also underwent extensive sit-to-stand training.The training lasted for 15 min/time,6 times/week for 4 weeks.All of the patients were assessed with respect to their body weight distribution,Berg balance scale (BBS) scores,timed up & go test (TUGT) times and using footprint gait analysis,before the treatment and 4 weeks post treatment. Results After 4 weeks of treatment body weight distribution,BBS scores,TUGT times and gait improved significantly in both groups.The BBS,TUGT and gait improvements were significantly greater in the observation than in the control group.There was no significant difference between the two groups in terms of body weight distribution. Conclusions Extensive sit-to-stand training combined with routine rehabilitation can distinctly improve the balance and walking of hemiplegic stroke survivors.

As the largest protective barrier of the body,gastrointestinal tract helps the organism resist the invasion and attacks of harmful substances from the outside world.There are three kinds of protective barriers:mechanical barrier,biotical barrier,and immune barrier.In recent years,increasing researches indicate the importance of gastrointestinal immune barrier and the important immunologic mechanism of enteral nutrition in improving the clinical outcome.This article reviews the effect of gut immunity in the improvement of clinical outcome by enteral nutrition.

Objective To investigate the biological effect of GM-CSF on splenic dentritic cells (DCs)when used to treat severe sepsis and the influence on the prognosis.Methods All 160 male Kunming mice were randomly(random number)divided into four groups:control group(n =50),the mice didnt receive special treatment; CLP group(n =42),the mice underwent cecal ligation and puncture;conventional treatment group(n =34),the mice received intraperitoneal injection of 5 mg/kg ceftriaxone at 12,24,36,48,60,72 and 84 h after surgery; GM-CSF treatment group(n =34),the mice received hypodermic injection of 20 μg/kg GM-CSF besides ceftriaxone at 12,36,60,and 84 h after surgery.The mice were sacrificed at 0,12,24,48 and 72 h after CLP by cervical dislocation.The amount of splenic DCs and apoptosis rate were measured by flow cytometry,and the serum concentrations of IL-12 were detected by ELISA in each group.Meanwhile the survival prognosis was observed at 96 h.Results At every time point,the apoptosis of splenic DCs increased and the amount markedly reduced in severe sepsis(P ＜0.05),the serum concentration of IL-12 increased on an one-way curve type(P ＜0.05).The treatment of cephalosporin exacerbated the loss of DCs(P ＜ 0.05),while hadnt any effect on IL-12(P ＞ 0.05).GMCSF treatment increased the amount of DCs(P ＜ 0.05),and decreased IL-12 concentrations(P ＜ 0.05).The OR of GM-CSF was 0.079 computed by Logist regression analysis.Conclusions GM-CSF treatment severe sepsis can increase the amount of splenic DCs,decrease serum levels of IL-12,and improve prognosis.
