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.

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

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.

Autophagy is an important pathway in the body to remove damaged cell organelles and dysfunctional proteins to maintain protein equilibrium and intracellular homeostasis by the lysosomal system .As a degenerative disease of central nervous system , the main feature of Alzheimer ’ s disease is abnormal protein aggregation .However , the role of autophagy in the pathogenesis of Alzheimer ’ s disease is not fully clear yet .The aim of this paper is to take β-amyloid peptide as a starting point to explore the relationship between autophagy and β-amyloid peptide in the pathogenesis of Alzheimer’s disease.

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.

To test whether Con A has antirejection effect on mouse islet allograft, 600-700 handpicked islets of C57BL/6 mice was transplanted beneath the kidney capsule of the streptozotocin induced diabetic BALB/C recipients. In control group the mean survival time (MST) of the grafts was 14.1?2.4 days. Treatment with Con A significantly prolong the MST of the islet allografts. In group with Con A treatment of the donor islets prior to the transplantation the MST was 25?5.4 days. The MST increased sigificantly after ip injection of Con A to recipient mice. The combined treatment of islet and recipient with Con A resulted in a prolongation of MST to 25.2?4.4 days. The experiments concerning the mechanisms of the antirejection effect of Con A showed that Con A was able to combine with the islet cell membrane well masking perhaps the histocmpatibility antigen. Furthermore the lymphocytes of mice after i. p Con A injection suppressed the lymphocyte proliferation reaction of the svnergic mice to mitogen.

Objective To compare the clinical effect of different treatment methods for the patients with great saphenous vein varicosity.Methods 140 patients with great saphenous varicose veins were selected,and according to random number table method they were divided into observation group and control group,70 cases in each group.The control group was given conventional stripped surgery,the observation group adopted high ligation joint int-racavitary laser treatment.The clinical effects of the two groups were compared.Results The operating time,intraop-erative blood loss,postoperative length of hospital stay,postoperative recurrence rate of the observation group were (51.32 ±4.97)min,(40.03 ±9.67)mL,(6.77 ±1.14)days,4.29%,respectively,which of the control group were (72.45 ±8.79)min,(108.68 ±17.75)mL,(11.69 ±2.68)days,20.00%,there were statistically significant differ-ences between the two groups(t =17.507,28.415,14.134,χ2 =8.101,all P <0.05).The incidence rate of postop-erative complications of the observation group was 4.29%,which of the control group was 14.29%,there was statisti-cally significant difference between the two groups(χ2 =4.155,P <0.05).The intervention pain score,the quality of life score of the observation group were (1.46 ±0.54)points,(90.04 ±9.77)points,which of the control group were (2.67 ±1.15)points,(78.61 ±6.82)points,there were statistically significant differences between the two groups (t =7.968,8.026,all P <0.05).Conclusion High ligation joint intracavitary laser in the treatment of great saphe-nous varicose veins is superior to the traditional operation method in operation time,intraoperative hemorrhage,length of hospital stay,and complications,and it can effectively relieve patients'pain and improve the quality of life.

Objective To sum up the clinical experience in the diagnosis and treatment of recurrent retroperitoneal malignant fibrous histiocytoma (RMFH). Methods[WT5”BZ] Clinical data of 29 recurrent RMFH from 1990 to 2002 were retrospectively analyzed. ResultsTwelve (41.4%) cases underwent total tumor resection after the first recurrence. Seven cases underwent multiple viscera resection,of which two did after the first recurrence,three after second and the other two after third recurrence. Twenty-five patients were followed up for 6 months to 8 years,The 1,3 and 5 year survival rate was 73.2%,46.7% and 19.8% respectively. [WT5”HZ]ConclusionTotal tumor resection is an effective way to treat RMFH,and multiple viscera combined resection increases the success rate of total tumor resection.
