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.

Chemotherapy plays an important role in advanced colorectal cancer. Patients may show various clinical response to selection different drugs. The importance of individual therapy based on pharmacogenomics has been emphasized in cancer therapy. To explore the individual therapy of colorectal cancer, the progress of molecular markers which influence the efficacy of anti-tumor drugs containing fluorouracil, oxaliplatin, CPT-11, monoclonal antibody drugs is reviewed in this article.

Forty-four guinea-pigs were sensitized by intramuscular inoculation with the same amount (0.8ml) of 5% egg albumin in water. 3 weeks after sensitization, the animals were rondomly divided into 1 groups (group J as control; group II given small dose of piperitone 0.08ml/ 100g body weight; group J given large dose of piperitone 0.12ml/100g body weight; group IX given promethazine 2.5mg 100g body weight) and subjected to anaphylactic insult by intra-cardiac injection of 1ml of 5% egg albumin in water under the protection of different dosege of piperitone, a terpene from cymbopogon distans. given intramuscularly. Results of the experiment indicates that piperitone had significant dose-effect relation protective effect against the anaphylactic insult on the guinea-pigs and suggests that piperitone might be used clinically for the treatment of asthma

Objective: To establish a HS CGC method for the analysis of residual petroleum ether (60～90?C) in Kanglaite Capsules.Methods: Headspace sampling, a fused silica analytical column with cross linked 95% dimethyl and 5% diphenyl siloxanes station phase (30m?320?m?0.25?m), column temperature at 40?C, a linear velocity of about 19 cm per second, FID detector.Results: The average recovery is 97.2% (RSD=2.87%, n=5). The minimal detection limit is 2.65?10 -8 g?mL -1 (signal/noise=1.3).Conclusion: The method is simple and accurate, and can be used as a control method for the residual organic solvent in the capsules.

Objective:To detect the changes on the ratio of T lymphocyte subgroup and immunoglobulin(Ig) in peripheral blood of patients with Primary extranodal lymphoma(PENL).Methods:The peripheral blood T lymphocyte subgroup ratio and immunoglobulin(Ig) complement C3,C4 content were detected by Flow Cytometry(FCM) and Immunoturbidimetry.Results:The numbers of CD3,CD4 or CD8 was lower(P

Thalassemia is inherited hemolytic anemia caused by globin production disorder,clinically known as beta thalassemia and alpha thalassemia resulted from beta and alpha chain synthesis disorder.Significant anemic clinical manifestations are observed in intermediate -level and severe -level patients with the 2 types of anemia, affecting greatly the growth and life quality of children patients who need blood transfusion to stay alive.The incidence rate of thalassemia is as high as 7% -20% in South China,so the prevention and standaridized treatment of thalasse-mia and the management over target population draw more attention.This paper is a review on the latest development of blood transfusion,chelation therapy,health education,birth intervention for thalassemia.

Objective To analyze the effect of Kangfuxin Liquidon on gingiva groove liquid interleukin 1β(IL-1β), prostaglandin E2 (PGE2), soluble adhesion molecule-1 (sICAM)in fixed orthodontic patients with gingivitis. Methods 96 cases of patients with fixed orthodontic gingivitis consult the draw method were divided into control group and experimental group, 48 cases in each group. The control group were treatedby gums clean, experimental group based on the control group were treattedby Kangfuxin Liquidon. The IL-1β, PGE2, sICAM-1 levels, periodontal status, the grade of swelling and pain, the clinical curative effect were compared between two groups. Results After treatment, the IL-1β, PGE2, sICAM levels of experimental group were lower than the control group (10.54±1.41) ng/L vs.(11.85±1.71)ng/L, (284.62±35.21) ng/L vs.(314.65±39.48)ng/L, (150.49±18.11) μg/L vs.(162.83±20.26) μg/L,the differences were statistically significant (P<0.05).The periodontal status, swelling and pain grading ofexperimental group were better than control group (P<0.05). Theeffective rate of experimental group was higher than the control group (95.83%vs.79.17%) (P<0.05). Conclusion Kangfuxin Liquidon can reduce fixed orthodontic patients with gingivitis gingiva groove IL-1β, PGE2, sICAM-1 levels, improve the periodontal status, relieve swelling and pain, improve the clinical curative effect.

Recent developments on separation and analysis of bacterial cells by capillary electrophoresis are reviewed. Based on bacterial surface characterization, capillary electrophoresis technique can be utilized for rapidly identify and quantify intact bacteria and microbes at a certain phase. The microbe-molecule interactions can also be described. The separation of microbes that can not be cultured in lab appears to be possible by this method. It makes profound effects on separation science and microbiology to establish capillary electrophoresis procedure for the separation and analysis of bacterial cells.

OBJECTIVE:To compare the effects and costs between metformin and acarbose when combined with insulin in treating type2diabetes mellitus.METHODS:Cost-minimization analysis in medical economy was applied to analyze the therapeutic effects,costs and cost related factors with the respect for the patients.RESULTS:There was no statistically sig?nificant difference in effects of the2therapeutic regimens.Total cost and drug cost per head in metformin group were1941.46yuan and138.86yuan respectively as compared with2308.37yuan and229.82yuan respectively in acarbose group.The analysis on cost related factors showed no statistical significance.CONCLUSION:Metformin combined with insulin is a preferable therapeutic regimen.
