Objective: To understand the significance of serum TK1 level change during chemotherapy of patients with non-Hodgkin's lymphoma. Methods: The serum TK1 levels were detected in 37 patients with non-Hodgkin's lymphoma by enhanced chemiluminecence assay before chemotherapy and one day, four weeks after chemotherapy. Results: The changes of serum TK1 levels were significantly different at different stages of treatment (P<0.01). Conclusion: Our findings indicate that serum TK1 change might be of great value in evaluating the treatment outcomes and predicting recurrence of patients with non-Hodgkin's lymphoma.

Objective To study the related factors in diabetic patients with lOwer extremital deep vein thrombosis(DVT) and the nursing strategy. Methods 58 diabetic cases underwent lower limbs 99mTc-MAA veins imaging and/or ultrasunography. The related laboratory data such as fasting plasma glucose(FPG),blood cholesterol, blood triglycerides and clinic informations such as age, disease courses, lower limbs symptoms (swelling, erooted veins and diabetic foot) and acute complication (diabetic ketoacidosis and hyperosmolar non ketotic diabetic coma) were collected simultaneously. The relationship of each factors with DVT incidence were analyzed. Results 28 patients (48.3%) complicated with lower limbs DVT. The DVT incidence was signifi-cantly different among patients with different age, disease courses, FPG, blood cholesterol, blood triglycerides, lower limbs symptoms and acute complication, respectively. No significant difference was seen in patients with different blood pressure, body weight index, diabetes type. Conclusions Various dangerous factors accumu-lating in DM such as old age, long disease courses, high FPG, high blood cholesterol and high blood triglyc-erides contribute to the high incidence of lower limbs DVT. Early intervention, comprehensive treatment and in-tensive nursing should be applied to reduce the incidence of DVT.

Objective To investigate apoptosis of polymorphonuclear neutrophil and activity of caspase-3 in the peripheral blood and discuss their correlation with development of multiple organ dysfunc- tion syndrome (MODS) after multiple injury. Methods A total of 55 patients with multiple injury were included in the prospective study, and divided into two groups, ie, MODS group (multiple injury patients who developed MODS,) and non-MODS group (multiple injury patients who were free from MODS). The activity of caspase-3 was detected by flow cytometry and the serum levels of IL-6 and IL-10 were detected by ELISA. Then, we evaluated whether the neutrophil apoptesis was correlated with the ser- um levels of IL-6 and IL-10 in patients with MODS. Results Compared with non-MODS group, neu- trophil apoptesis was significantly reduced and activated caspase-3 decreased significantly in MODS group (P <0.05). In MODS group, serum IL-6 was increased significantly while serum IL-10 was decreased significantly compared with non-MODS group. The apoptosis of neutrophil in multiple injury patients with MODS had a negative correlation with IL-6 levels but a positive correlation with IL-10 levels. Conclu- sions The delayed apoptosis of neutrophil due to decreased activated caspase-3 may play partial roles in the development of MODS after multiple injury. IL-6 and IL-10 may contribute to the apoptotic changes.

Objective To study the related risk factors of pulmonary embolism(PE) in diabetic patients.Methods 58 diabetic cases were underwent lower limbs 99mTc-MAA veins imaging(and/or ultrasonography) and pulmonary perfusion imaging.The related laboratory data [fasting blood glucose(FBG),blood cholesterol,blood long chain triglycerides(LCT)]and clinial informations [age,disease courses,chest symptoms(chest pain and short of breathe),lower limbs symptoms(swelling,crooted veins and diabetic foot) and acute complication(diabetic ketoacidosis and hyperosmolar non ketotic diabetic coma)]were collected simultaneously.SPSS was used for χ2-test and Logistic regression analysis.Results 28 patients(48.3%) were showed to be with lower limbs deep vein thrombosis (DVT) and by 99Tcm-MAA imaging,10 cases(17.2%) with PE.The PE ratio(32.1%) of the patients with DVT was more higher than no DVT(3.3%)(χ2 = 6.53,P＜0.05).Single factor analysis showed the PE ratios had significant difference to factors of chest symptoms,lower limbs symptoms and acute complication(all P＜0.05),respectively.There were no significant difference in other factors of age,disease courses,FBG,blood cholesterol,LCT,blood pressure,weight index,DM type(all P＞0.05),respectively.Multiplicity analysis indicated:the related risk factors of PE included chest symptoms(Score = 13.316,P＜0.01) and lower limbs symptoms(Score = 7.780,P＜0.01).There were no significant differences in other factors(all P＞0.05),respectively.Conclusion The serious DM with chest symptoms,lower limbs symptoms and/or DVT could be controlled as early as possible by all kinds of treatment.It would decrease the PE complication.

Background and purpose: Lymph node (LN) metastasis of esophageal cancer of neck rate higher, but there is little bulk reports. This article aimed to analyze the characteristics of cervical lymph node metastasis (CLN) in thoracic esophageal squamous cell carcinoma (TE-SCC) and the clinical role. Methods:A total number of 1 131 TE-SCC patients underwent radical esophagectomy plus three-ifeld lymph node dissection at Fujian Provincial Tumor Hospital between Jan. 1993 to Dec. 2003, during which, 367 patients had pathological metastasis of CLN. Results:The metastatic rate of CLN was 33.2%for the entire group, 43.7%, 33.0%and 16.0%for the upper, middle and lower TE-SCC respectively. Single factor analysis showed that the metastatic rate of CLN was relevant with the tumor site, pathological differentiated degree, lesion length showed in X-ray, pT stage and the number of CLN (P<0.05). But multivariate regression analysis showed that the metastatic rate of CLN was just relevant with the tumor site, pT stage and the number of CLN (P<0.05). Metastasis of cervical paraesophageal lymph nodes was the most common, and Background and purpose: Lymph node (LN) metastasis of esophageal cancer of neck rate higher, but there is little bulk reports.

This study is to explore whether the Wnt/beta-catenin signaling pathway is involved in the process of tripchlorolide (T4) protecting against oligomeric Abeta(1-42)-induced neuronal apoptosis. Primary cultured cortical neurons were used for the experiments on day 6 or 7. The oligomeric Abeta(1-42) (5 micromol x L(-1) for 24 h) was applied to induce neuronal apoptosis. Prior to treatment with Abeta(1-42) for 24 h, the cultured neurons were pre-incubated with T4 (2.5, 10, and 40 nmol x L(-1)), Wnt3a (Wnt signaling agonists) and Dkk1 (inhibitors) for indicated time. Then the cell viability, neuronal apoptosis, and protein levels of Wnt, glycogen synthase kinase 3beta (GSK3beta), beta-catenin and phospho-beta-catenin were measured by MTT assay, TUNEL staining and Western blotting, respectively. The result demonstrated that oligomeric Abeta(1-42) induced apoptotic neuronal cell death in a time- and dose-dependent manner. Pretreatment with T4 significantly increased the neuronal cell survival and attenuated neuronal apoptosis. Moreover, oligomeric Abeta(1-42)-induced phosphorylation of beta-catenin and GSK3beta was markedly inhibited by T4. Additionally, T4 stabilized cytoplasmic beta-catenin. These results indicate that tripchlorolide protects against the neurotoxicity of Abeta by regulating Wnt/beta-catenin signaling pathway. This may provide insight into the clinical application of tripchlorolide to Alzheimer's disease.

Tetradrine-tashionone II(A)-PLGA composite microspheres were prepared by the SPG membrane emulsification method, and the characterization of tetradrine-tashionone II(A) -PLGA composite microspheres were studied in this experiment. The results of IR, DSC and XRD showed that teradrine and tashionone II(A) in composite microspheres were highly dispersed in the PLGA with amorphous form. The results of tetradrine-tashionone II(A) -PLGA composite microspheres in vitro release experiment showed that the cumulative release amounts of tetradrine and tashionone II(A) were 6.44% and 3.60% in 24 h, and the cumulative release amounts of tetradrine and tashionone II(A) were 89.02% and 21.24% in 17 d. The process of drug in vitro release accorded with the model of Riger-Peppas. Tetradrine-tashionone II(A) -PLGA composite microspheres had slow-release effect, and it could significantly reduce the burst release, prolong the therapeutic time, decrease the dosage of drugs and provide a new idea and method to prepare traditional Chinese medicine compound.
