OBJECTIVE:To investigate chemotherapeutic efficacy and safety of Paclitaxel combined with lobaplatin by inter-ventional embolization for cervical cancer. METHODS:Totally 68 cases of cervical cancer patients selected from our hospital dur-ing May 2010-Mar. 2014 were divided into control group and observation group according to therapy plan,with 34 cases in each group. Control group was given Paclitaxel liposome for injection 175 mg/m2 added into 5% Glucose injection 250 mL,ivgtt+Loba-platin for injection 80 mg/m2 added into 5% Glucose injection 250 mL,ivgtt. Observation group was given Paclitaxel liposome for injection 175 mg/m2+Lobaplatin for injection 80 mg/m2+5% Glucose injection 10 mL via percutaneous catheter after selecting uter-ine artery and tumor vessel by arterial catheterization arteriography,gelfoam embolization. Both groups were treated in the first day of every treatment course,21 d as a treatment course,for 3 courses. Clinical efficacies were observed in 2 groups as well as the levels of T lymphocyte subsets(CD4+,CD8+,CD4+/CD8+)before and after treatment. The occurrence of ADR during treatment,lo-cal recurrence and metastasis after 2 years,and survival situation were recorded. RESULTS:The total response rate of observatio group(85.29%)was significantly higher than that of control group(61.76%),with statistical significance(P<0.05). Before treat-ment,there was no statistical significance in the levels of CD4+,CD8+ or CD4+/CD8+ between 2 groups (P>0.05). After treat-ment,CD4+and CD4+/CD8+of 2 groups were increased significantly,while CD8+was decreased significantly;above indexes of ob-servation group were improved significantly compared to control group,with statistical significance (P<0.05). The survival time of observation group [(22.58±0.61)months] was significantly longer than that of control group [(17.61±1.32)months],and 2-year survival rate(70.59%)was significantly higher than control group(47.06%),with statistical significance(P<0.05). There were no statistical significance in incidence of disease control,incidence of total ADR and incidence of local recurrence and metastasis between 2 groups (P>0.05). CONCLUSIONS:Paclitaxel combined with lobaplatin by interventional embolization show definite chemotherapeutic efficacy for cervical cancer,and can improve the levels of T lymphocyte subset with good safety.

Objective:To study the effects of deoxyadenosine(dAdo) on methotrexate (MTX) induced suppression of inflammatory bone destruction.Methods:The culture system of whole bone marrow cells (WBMCs) was utilized to evaluate osteoclastogenesis.TRAP staining and μCT analysis were utilized to evaluate osteoclastogenesis and bone destruction in adjuvant arthritis rats.Results:In the bone marrow culture system,MTX-induced suppression of osteoclastogenesis was abrogated by the addition of dAdo.dAdo canceled MTX-induced suppression of osteoclastogenesis in the rats with arthritis,and significantly abolished the therapeutic effects of MTX on inflammatory bone destruction in the rats.Conclusion:The accumulation of dAdo may be one cause of the losing effectiveness of MTX in bone destruction.

Objective:To explore the effect of Rho kinase inhibitor on intestinal injury in septic rats and its possible mechanism.Methods:Thirty-two male Sprague-Dawley (SD) rats were randomly divided into sham operation group (Sham group), Rho kinase inhibitor Y-27632 control group (Y+Sham group), sepsis model group [cecal ligation and puncture (CLP) group] and Y-27632 pretreatment group (Y+CLP group), with 8 rats in each group. Rat sepsis model was reproduced by CLP. The rats in the Sham group and Y+Sham group were only separated and moved the cecum without ligation and perforation. The rats in the Y+Sham group and Y+CLP group were pretreated with intraperitoneal injection of Y-27632 solution 5 mg/kg 15 minutes before operation; the rats in the Sham group and CLP group were intraperitoneally injected with the same amount of phosphate buffered saline (PBS). Twenty-four hours after operation, the heart blood was collected and the serum diamine oxidase (DAO) content was determined by enzyme-linked immunosorbent assay (ELISA). Then the small intestine tissue was collected, the pathological changes of the intestinal tissue were observed under the light microscope after hematoxylin-eosin (HE) staining, and Chiu's score was performed. The positive expressions of Rho-related coiled-coil kinase 1 (ROCK1) and nuclear factor-κB (NF-κB) in intestinal tissue were detected by immunohistochemistry. ELISA was used to detect the levels of tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) in intestinal tissue homogenate.Results:The intestinal tissue structure of the Sham group and Y+Sham group was intact and the mucosa was arranged neatly. Compared with the Sham group, the intestinal mucosa of the CLP group was arranged disorderly, with a large number of inflammatory cells infiltration, and the Chiu's score was significantly increased (3.83±0.27 vs. 0.12±0.11, P < 0.05), indicating that those rats suffered from septic intestinal injury. Compared with the CLP group, the degree of necrosis of intestinal epithelial cells in the Y+CLP group was reduced, a small amount of inflammatory cells infiltration was seen, and the Chiu's score was significantly decreased (2.85±0.21 vs. 3.83±0.27, P < 0.05), indicating that Y-27632 pretreatment could alleviate intestinal injury in septic rats. Compared with the Sham group, the positive expressions of intestinal tissue ROCK1 and NF-κB, the contents of serum DAO and intestinal homogenate TNF-α in the CLP group were significantly increased [ROCK1 expression ( A value): 0.19 (0.18, 0.22) vs. 0.10 (0.09, 0.11), NF-κB expression ( A value): 0.40±0.02 vs. 0.15±0.01, DAO (ng/L): 287.81±23.31 vs. 144.92±17.72, TNF-α (ng/L): 101.08±5.62 vs. 74.81±5.56, all P < 0.05], the level of intestinal homogenate IL-10 was significantly decreased (μg/L: 55.16±5.20 vs. 95.95±7.53, P < 0.05). Compared with the CLP group, the positive expressions of intestinal tissue ROCK1, NF-κB, the contents of serum DAO and intestinal homogenate TNF-α in the Y+CLP group were significantly decreased [ROCK1 expression ( A value): 0.15 (0.13, 0.18) vs. 0.19 (0.18, 0.22), NF-κB expression ( A value): 0.28±0.01 vs. 0.40±0.02, DAO (ng/L): 243.34±19.76 vs. 287.81±23.31, TNF-α (ng/L): 90.41±8.79 vs. 101.08±5.62, all P < 0.05], while the level of intestinal homogenate IL-10 was significantly increased (μg/L: 66.15±5.74 vs. 55.16±5.20, P < 0.05), indicating that the protective effect of Y-27632 pretreatment on sepsis intestinal injury rats might be related to the regulation of RhoA/ROCK1/NF-κB signaling pathway. Conclusion:Rho kinase inhibitors can reduce intestinal injury in septic rats, and the mechanism may be related to inhibiting RhoA/ROCK1/NF-κB signaling pathway and reducing intestinal inflammation in septic rats.
