ABSTRACT

Objective The use of targeting therapy for the treatment of gastric glandular cancer has been a hot topic in recent years. This study aims to clarify that through what ways the histone deacetylase inhibitor MS-275 completes its selectively killing effect on gastric glandular cancer cell line SGC-7901. Methods SGC-7901 cells and GES-1 cells were respectively cultured for 24h, with(10-100) μmol/L concentrations of MS-275. (1) The survival rate of SGC-7901 cells, GES-1 cells and the normal cells were analyzed by WST-1; (2) The change of the mitochondrial membrane potential in SGC-7901 was estimated by flow cytometry;(3) The expression levels of p21, p27, p57, cyclinB1, cyclinD1 were determined by Western blot and PCR methods. Results (1) MS-275 could decrease the survival rate of SGC-7901 cells, the effect was significantly enhanced with the increasing of the concentration (P<0.05), but MS-275 showed no obvious effect on normal gastric mucosa epithelial cells GES-1; (2) MS-275 treatment could decreased the mitochondrial membrane potential of SGC-7901 cells (P<0.05); (3) MS-275 treatment could increase the relative contents of p21, p27, p57 genes and their protein and, at the same time, decrease the relative contents of CyclinB1 and CyclinD1 (P<0.05). Conclusion MS-275 treatment can selectively kill gastric glandular cancer cells SGC-7901 through several possible ways, such as inducing mitochondrial apoptosis and regulating the expression levels of cell cycle-related genes and proteins.

ABSTRACT

Objective To evaluate the clinical efficacy and safety of two kinds of uterine artery perfusion chemotherapy plus embolization (UACE) in treating ectopic pregnancy (EP). Methods A single center, randomized, double-blind, controlled clinical trial was carried out at authors hospital. A total of 50 cases of EP patients were randomly and equally divided into the study group (perfusion chemotherapy of MTX and 5-FU plus embolization therapy) and the control group (perfusion chemotherapy of pure MTX plus embolization therapy). After UACE, the serumβ-HCG value, the clinical healing time and the tubal patency rate were determined at different time, and the adverse events were recorded. The results were statistically analyzed by using t test, and χ2 test, and the data were compared between the two groups. Results One patient in both groups was excluded from the study. In the remaining 48 patients, one patient of the control group failed to respond the treatment, so the overall cure rate was 97.9%. The differences in the main effect of treatment method and the time interaction of the serum β-HCG values between the two groups were not statistically significant (P > 0.05), while the difference in the time effect between the two groups was statistically significant (P 0.05). The tubal patency rate of the study group and the control group was 76.2%and 78.9%respectively, and no statistically significant difference existed between the two groups (P > 0.05). The adverse events in both groups were mild, and the occurrence of the adverse events in the study group and the control group was 58.3% and 26.1% respectively, and the difference between the two groups was statistically significant (P <0.05). Conclusion Two kinds of interventional methods have the same clinical curative effect. However, the incidence of adverse events in the control group is lower than that in the study group. Therefore, in treating ectopic pregnancy perfusion chemotherapy with MTX only is recommend.

ABSTRACT

Objective To evaluate the efficacy of the combination of percutaneous transhepatic embolization of gastroesophageal varices (PEGV) and partial splenic embolization(PSE) for the treatment of variceal bleeding. Methods Fifty patients with cirrhosis who fit in with the requirements of the study were randomly divided into dual-interventional group and surgical group. The patients in dual-interventional group were treated with PEGV together with PSE, and the patients in surgery group were treated with Hassab's operation. After the procedure all the patients in two groups were followed up periodically. The endoscopy, B ultrasonography, liver function tests and hematologic examinations were performed 24 months after the therapy, and the results were statistically analyzed. Results Fifty patients were enrolled in this study. The procedures of embolization and surgery were successful in all patients. In dual-interventional group, the whit eblood cell and platelet counts were (2.33±0.65) 10~9/L and (3.63±1.05) ×10~9/L respectively before the treatment and were (7.98±3.0) ×10~9/L and (163±91)× 10~9/L respectively 24 months after the treatment (P<0.05). The diameter of theportal vein was (1.47±0.25) cm before the treatment and was(1.31±0.23) cm 24 months after the treatment (P<0.05). The severity of esophageal varices decreased from grade Ⅲ to lower grade Ⅱ in 11 patients, and from grade Ⅱ to lower grade Ⅰ in 6 patients 24 months after procedure. Portal thrombosis occurred in 1 case. The recurrent bleeding rate was 16% (4/25) 24 months after treatment. Three patients died of the recurrent bleeding, one patient died of hepatic failure. In surgical group, the white blood cell and platelet counts were (2.2±0.60) ×10~9/L and (41±12.5) ×109/L before treatment, and were (9.3±2.56)×10~9/L and (321±12.5)×10~9/L 24 months after treatment (P<0.05). The diameter of the portal vein was (1.43±0.22) cm before the treatment and was (1.28±0.18) cm after the treatment (P<0.05). The severity of esophageal varices decreased from grade Ⅲ to lower grade Ⅱ in 13 patients, and from grade Ⅱ to lower grade Ⅰ in 7 patients. Four patients developed portal thrombosis after the procedure. The recurrent bleeding rate was 20%(5/25), 2 patients died of hepatic failure after the surgery, 2 died of recurrent bleeding. Conclusion In treating patients with cirrhosis, the combination of PGEV and PSE, regarded as dual-interventional therapy, is very effective, especially in controlling recurrent bleeding and in improving white blood cell and platelet counts.

ABSTRACT

BACKGROUND: Negative pressure of limbs is a convenient, safe and unwound way to treat peripheral arterial occlusion and to relieve pain.Prostaglandin E1 can directly rellax vascular smooth muscles and relieve pain on nerve.OBJECTIVE: To observe the effect of negative pressure of limbs immunologic reaction positive nerve fiber of prostaglandin E1 in sensory nerve fiber of central nervous system of dogs with peripheral arterial occlusion.DESIGN: Randomized controlled animalstudy.SETTING: Tumor Center of Zhujiang Hospital affiliated to Southern Medical University, the Third General Surgery of Xijing Hospital affiliated to the Fourth Military Medical University of Chinese PLA.MATERIALS: The experiment was carried out in the Animal Laboratory of Xijing Hospital affiliated to the Fourth Military Medical University of Chinese PLA from April 2003 to May 2004. A total of 17 healthy adult hybrid dogs were randomly divided into three groups: treatment group (n=10),non-treatment group (n=5) and normal control group (n=2), according to randomly digital table.METHODS: Ischemic models of left hindlimb were established in treatment group and non-treatment group. Fourteen days later, dogs in treatment group were given negative pressure (-12kPa) treatment for 15 minutes. The negative pressure was done once a day for 10 successive days.However, negative pressure was not done in non-treatment group. Animals were not interfered in normal control group.MAIN OUTCOME MEASURES: Twenty-four days later, dogs in each group were anesthetized and sacrificed. L1-L5 spinal cord and ganglia of dorsal root were selected and stained with immunohistochemical method to detect average giay value of immunologic reaction positive nerve fiber of prostaglandin E 1.RESULTS: A total of 17 dogs were involved in the final analysis. Average gray values of immunologic reaction positive nerve fiber of prostaglandin E1 in spinal cord were 75.23±4.3 in non-treatment group, 43.22±3.7 in treatment group and 22.00±5.8 in normal control group; average gray values of immunologic reaction positive nerve fiber of prostaglandin E1 in ganglia of dorsal root were 67.12±2.3, 40.08±3.8, 27.64±2.7, respectively.There was no significant difference among the three groups (P<0.01).CONCLUSION: After onset of peripheral arterial occlusion, amount of immunologic reaction positive nerve fiber of prostaglandin E1 in spinal cord and ganglia of dorsal root of distal limbs is increased remarkably, and this may be a kink of auto-protective mechanism of organism. Negative pressure can relieve pain of limbs and decrease damaged-stimulated transmission of peripheral arterial occlusion.
