Purpose:To explore the role of terminal restric tion fragments (TRFs), telomerase activity and expression of human telomerase re verse transcriptase (hTERT) in colorectal carcinoma. Methods:The telomere length, telomerase activity and expression of hTERT were studied with Southern-blot, TRAP and immunohistochemistry, respe ctively. Results:TRFs in cancer tissue was much shorter than in the adja cent tissues and normal mucosa, and TRFs was decreased gradually along with the development in cancer stage.The expression of Telomerase in colorectal carcinoma tissue was significantly higher than that in other tissues (P

ObjectiveTo study the effects of liver cancer vaccine activated TIL on primary liver cancer (PLC).Methods Twenty-six patients with PLC were treated with stimulated TIL by liver cancer vaccine. The CD3?CD4?CD8?CD4/CD8, NK activity and levels of serum sIL-2R were assayed before and after the treatment, the survival tates of 1, 2 and 3 year were analysed. ResultsCD3?CD4?CD4/CD8 and the activity of NKC were 55?3?76?5;28.3?1.6?44.6?2.3;1.19?0.22?2.21?0.36;9.8?1.2?17.4?2.2, at 19th and 30th day, respectively after treatment of TIL. The difference was all significant compared with the controls (P

Objective To observe the application effect of wuhuangyou in the prevention of radiodermatitis for tumor patients undergoing chemotherapy and evaluate its applicability. Methods We divided 203 tumor patients undergoing chemotherapy into 3 groups.Application of wuhuangyou,meibao and routine health education were used in each group. Results Statistical difference existed in the incidence rate and degree of radio-dermatitis between the three groups,among which wuhuangyou proved to possess the best effect,P ＜ 0.01. Conclusion The application of wuhuangyou was safe,effective,economical in the prevention of radio-dermatitis.It could relieve the pain of patients and guarantee the smooth process of chemotherapy.

Objective To measure hepatic blood flow of the normal liver and cirrhotic liver with hepatocellular carcinoma using multi-slice spiral CT(MSCT),and to evaluate the feasibility of the quantitative judgement of classification of liver cirrhosis with CT perfusion imaging.Methods CT dynamic perfusion imaging was performed in 53 subjects,including 32 patients of liver cirrhosis with hepatocellular carcinoma and 21 patients without liver disease(control subjects).The patients of liver cirrhosis with hepatocellular carcinoma were divided into three groups by CT morphologic classification :17 were classified as light liver cirrhosis group,8 as moderate group,7 as severe group.The parameters of CT perfusion included blood flow(BF),blood volume(BV),mean transit time(MTT),hepatic arterial fraction(HAF)and impulse residue function to(IRF To).The parameters were analyzed by the CT perfusion 3 software package(GE)with deconvolution method,and the correlation of the CT morphologic classification of liver cirrhosis with Child-Pugh functional classification was further evaluated.100 g-1,(17.81±6.59)ml/100 g,(9.52±3.08)s,0.20±0.08 and(4.38±2.35)s,respectively,while 0.27±0. 09 and (4. 14±2. 16)s, respectively. The mean BF, BV and HAF between normal livers and liver cirrhosis were statistically significant (P＜0. 05), and there were significant statistical differences in BF, BV and HAF among light, moderate and severe liver cirrhosis (P＜0. 05). The CT morphologic classification of liver cirrhosis was correlated positively with Child-Pugh classification (r=0. 935, P=0. 001 ). Conclusions Hepatic perfusion with MSCT can reflect the change of blood flow of cirrhotic liver, and MSCT perfusion can quantitatively evaluate the liver cirrhosis degree of patients with hepatocellular carcinoma.

Objective　To study the applicable value of resection of segment VIII after cryotherapy for hepatocarcinoma. Methods　As for 8 patients with hepatocarcinoma in segment VIII, the turnor was dealt with cryotherapy before resected. Results　All the tumors were resected smoothly after cryotherapy with less bleeding (mean 430ml), less time (mean 138min) and without severe complications or postoperative death in this series. Conclusions　Resection of segment VIII after cryotherapy for hepatocarcinoma is proved safe and feasible, whitch can decrease blood loss, save time, reduce tissue injury, and decrease postoperative recurrence.

Objective To investigate expression and promoter methylation status of BRCA1 in sporadic breast cancer .Meth-ods The expression of BRCA1 mRNA and protein were detected in 60 cases of sporadic breast cancer ,the adjacent breast tissues , and 30 cases of breast benign lesion tissue by RT-PCR and and immunohistochemical staining respectively .The methylation status of BRCA1 promoter in those tissues were detected using bisulfite genomic sequencing PCR (BSP) combined with TA clone for se-quencing .The relation between BRCA1 expression in sporadic breast cancer and promoter methylation status was analyzed .Results The expression level of BRCA1 mRNA and protein were down-regulated in sporadic breast cancer tissues compared to the corre-sponding adjacent breast tissues and breast benign lesion tissue(P<0 .001) .The positive rates of BRCA1 protein was 51 .7% (31/60)in sporadic breast tissue ,which were significantly lower than those of in the adjacent breast tissues 71 .7% (43/60)and breast benign lesion tissue 66 .7% (20/30)(P< 0 .001) .The methylation rate of BRCA1 promoter CpG was 31 .7% (19/60)in sporadic breast ,while it wasn′t found in adjacent breast tissues and breast benign lesion tissue(P=0 .000) .The statistical analysis showed the expression of BRCA1 had significant negative correlation with promoter methylation(r= -0 .345 ,P=0 .007) .Conclusion The hypermethylation of BRCA1 promoter could induce BRCA1 down-regulating ,which may be involved in the occurrence and develop-ment of sporadic breast cancer .

Objective To ummarized the clinical characteristics of lactic acidosis combined with hypoglycemic coma,diabetic ketoacidosis and hyperkalemia,so to improve the physician's treatment ability by summary the clinical feature of lactic acidosis combined with hypoglycemic coma,diabetic ketosis and hyperkalemia.Methods Analyzed the clinical characteristics and disease development of one case with lactic acidosis combined with hypoglycemic coma,diabetic ketoacidosis and hyperkalemia,and reviewed literature.Results The patient had hypoglycemia and acidosis at the same time due to taking phenformin and glibenclamide.After 2 days,the patient was better through correcting acidosis,intravenous fluid therapy,lowering blood potassium and controlling blood glucose.Conclusion Because acidosis caused the potassium transfer from intracellular to extracellular,the latter leads to hyperpotassemia,lactic acidosis caused by phenformin should be treated with intravenous fluid therapy,correcting acidosis.

Conclusions Resection of segment VIII after cryotherapy for hepatocarcinoma is proved safe and feasible, whitch can decrease blood loss, save time, reduce tissue injury, and decrease postoperative recurrence.

Lung cancer,a malignant tumor with high incidence and mortality rate,is characterized by multiple types,high malignancy and poor prognosis.Immunotherapy is to stimulate and enhance immune system of the host to achieve the purpose of controlling and killing tumor cells,and has been proven to have good therapeutic effects on many types of cancer.Immunogenic cell death(ICD)is a programmed cell death characterized by the release of large amounts of damage-associated molecular pat-terns(DAMPs).After treatment of certain chemotherapy drugs,physical therapy,biological therapy or combination therapy,lung cancer cells will undergo ICD,altering from non-immunogenic to immunogenic.Immune cells will then be recruited and ac-tivated,and finally activate and enhance anti-tumor immune response in the body.This article reviews the mechanism of ICD and the application of ICD inducers in the treatment of lung cancer.
