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 study the efficacy, safety and related characteristics of ethylcellulose microcapsules containing tubeimoside as a vascular embolization agent. Methods The ethylcellulose microcapsules containing tubeimoside was prepared using tubeimoside from bolbostemma paniculatum of Chinese medicinal herb as the core, and ethylcellulose as the shell. Transcatheter renal arterial embolization was performed with the microcapsules in 30 New Zealand white rabbits. Results The microcapsules were white, spherical, and smooth particles, with its size to range from 40-180 μm, and its drug content was 36%(W/W); It was divergened best in 40% meglucamine diatrizoate and suspended stably, easily injected through 3 F catheter without occlusion. All of the microcapsules ruptured in about 20 days when immersed in physiological saline at 37℃. The embolized kidneys were smaller than the normal kidneys in weight and volume after 30 days(tw=102.1, tv=38.0, P<0.001). Serial slices of the kidneys showed that the microcapsules remained mainly at the interlobular artery and the arterial arch, which measured from 110 μm to 350 μm in diameter. The vessels maintained occlusive after 30 days without formation of collateral circulation. Conclusion Ethylcellulose microcapsules containing tubeimoside were safe and effective with angioembolic function and slow-release. It was a potential peripheral artery embolization agent.

ABSTRACT

Objective To enhance the cognition about the adult contagious atypical pneumonia for an expectation of earlier diagnosis, prevention and treatment.Methods We analyzed and summarized X-ray lung and clinical characteristics of 34 patients with contagious atypical pneumonias who were admitted to our hospital from Feb to April. 2003.Results X-ray findings of lung were characterized by mostly involving unilateral and presenting ill defined cloud or patches-form opacities. These lesions progressed and varied rapidly. The clinical manifestations were characterized by the onset of fever (34/34), mostly associated with systemic and joint aching pains (29/34) and dry coughs (29/34). Leucocyte counts showed normal or lower than normal. Patient with a continuing high fever might tend to develop ARDS (2/34). All the 34 patients recovered after combined therapies (anti-inflammation, anti-virus and promoting immunity ) and were discharged from hospital. The average in-hospital days were (10.6?4.2) days. Conclusion X-ray examination is the main method for the early diagnosis and observing state-variation. The predominant clinical features of this disease are fever, dry cough, aching pain in extremities, unconspicuous pulmonary signs as well as hemogram not rising, a continuing high fever may lead to the tendency of ARDS.

ABSTRACT

Objective To evaluate the factors of influence on the prognosis and survival rate in patients of primary hepatic cellular carcinoma(HCC) after interventional therapy.Methods 258 cases of HCC were treated with interventional therapy,the data of these cases and the survival rate were analysed.Results The prognosis in patients with HCC was relation to the hepatic function,therapeutic methods and accumulation of iodized oil by analysis of Cox Regression.The cumulative survival rate was different in HCC with different pathological type,different grade of hepatic function,with or without tumor embolus in portal vein,different cumulation of iodized oil and different therapetic methods,there was significance in statistics between most of them.Conclusion Cox Regression model can be used to analyse synthetically the factors that significantly affected the survival period in the patients with HCC.

ABSTRACT

Objective To increase the ability to recognize the characteristic MRI features of multiple sclerosis (MS) in the spinal cord. Methods Fifteen patients with MS underwent MR examination of the cervical spine. The MS plaques were evaluated for lesion location, length,size on cross-section and lesion enhancement. MRI features of intraspinal tumor of spinal cord, cervical spondylopathy of myeloid form and transverse myelitis were analyzed and compared. Results The lesion mainly developed in cervical cord in the 15 patients. The lesions were less than five vertebra body in length. MRI features showed that involved cord segment was mild swollen with smooth periphery in sagittal section;the plaques showed iso-mild hypointense on T 1WI and hyperintense on T 2WI; the plaques were located peripherally and occupied less than 50%of the cross-sectional area of the cord; the lesions in active stage were enhanced by Gd-DTPA or no enhancement, the enhanced size of plaque was smaller than the extent showing hyperintense on T 2WI. The case of several onset showed various enhancement. Conclusion MS of spinal cord has characteristic feature on MRI, this can provide reliable proof for clinical diagnosis.
