In addition, it could decrease cholesterin content.

Objective To discuss the role of matrix metalloproteinase-8(MMP-8) mRNA in apical granuloma and periapical cyst by detecting the its expressions in the periapical granuloma and periapical cyst.Methods Reverse transcription polymerase chain reaction(RT-PCR) technique was used to measure the expressions of MMP-8 mRNA in 22 cases of periapical granuloma,11 cases of periapical cyst and 10 cases of normal periapical tissues.Results The positive rates and the levels of MMP-8 mRNA expression in apical granulomas and periapical cysts were significantly higher than those in normal tissues(P0.05).Conclusion The expression of MMP-8 may play an important role in the pathogenesy of apical granuloma and periapical cyst,and it may be involved in the process of bone destruction.

Objective To investigate the efficacy and side effects of MINE regimen, as a salvage regimen, in treating patients with recurrent and refractory intermediate grade non-Hodgkin lymphoma(NHL).Methods 45 patients failing to CHOP or CHOP-like regimen were treated with MINE regimen and every patient had received 2-6 cycles of treatment. IFO 15 g/m2, ivgtt on d1-3, combined with mesna 400 mg iv for3 times on Oh, 4h, 8h after IFO ivgtt; MIT 10 mg/m2 ivgtt on dl; VP1665 mg/m2 ivgtt on d1-3. 21-28 daysconsisted of one cycle. The therapeutic effects and side effects were evaluated according to the WHO criteria.Results In all 45 patients, 53.3 % of overall response rate were achieved CR for 9 cases, 15 cases PR, 13 cases SD and 8 cases PD. Main side effects were myelosuppression, nausea, vomit, alopecia, etc. Conclusion MINE regimen is an effective and safe salvage regimen in treating patients with recurrent and refractory intermediate grade NHL. Further clinical study on the application of MINE regimen is recommended.

Objective To investigate the effect of infrasound on the growth of bone marrow mescenchymal stem cells (BMSCs) and seek the most reasonable duration for using infrasound. Methods The primary BMSCs were obtained from Sprague-Dawley rats through whole bone marrow adherent cultivation.The cells of passage 3 were divided into trial groups treated with infrasound for 10 min,30 min or 60 min,and control groups which were not treated with infrasound but exposed to air for the same durations.The vitality of cell proliferation was measured using the CCK8 method.Apoptosis and the cell cycle were analysed with flow cytometry (FACS). Results After cultivation for 72 h,the optical density (OD) values for BMSCs treated with infrasound for 10 min,30 min and 60 min were 1.480 ± 0.030,1.348 ± 0.030,1.493 ± 0.030 respectively and after 96 h they were 1.774 ± 0.030,1.731 ± 0.030 and 1.833 ± 0.030.All of which were significantly greater than in the control groups ( 1.479 ± 0.030,1.267 ±0.030 and 1.227 ± 0.030 after 72 h and 1.567 ± 0.030,1.563 ± 0.030 and 1.632 ± 0.030 after 96 h).With the extension of the treatment duration,the OD values of the BMSCs increased or increased after decreasing,and the OD value for BMSCs treated with infrasound for 60 min was the highest.The FACS results indicated no effect of infrasound on apoptosis of BMSCs when the treatment duration was 30 min,but that cell apoptosis could be inhibited when the treatment duration was 10 min or 60 min.The early phase apoptosis rates were 1.07％ ± 0.12％ and 0.97％ ±0.21％ in the trial groups treated for 10 min and 60 min respectively,and 1.43％ ± 0.06％ and 3.33％ ± 0.15％ in the respective control groups,a highly significant difference.The results of cell cycle analysis showed infrasound could disturb the cell division of BMSCs significantly when the treatment duration was less than 30 min,but there was no significant effect when the treatment duration was 60 min. Conclusions Infrasound can promote cell proliferation and disturb cell division,but it did not cause apoptosis of BMSCs.When the treatment duration was 60 min,cell proliferation improved steadily,the apoptosis rate decreased,and the cell cycle did not change.So 60 min is the most reasonable treatment duration for infrasound.

Objective To observe the effects of melatonin on synaptic plasticity impaired by spinal cord injury in rats. Methods A total of 54 female Sprague-Dawley rats were divided into sham group (n=18), control group (n=18) and melatonin group (n=18). Spinal cord inju-ry model was established with modified Allen's method at T10 (10 g from 25 mm height). The number of neurons and the expression of the Nissl body were detected with immunofluorescence and Nissl staining. The expression of neurofilament-200 (NF-200), brain-derived neuro-trophic factors (BDNF), Synapsin I and growth-associated protein-43 (GAP-43) was detected with Western blotting. Results Seven days af-ter injury, the number of motoneurons, the expression of Nissl body in motoneurons, and the expression of BDNF, Synapsin I and GAP-43 decreased in the control group compared with those in the sham group, and they increased in the melatonin group compared with those in the control group. Conclusion Melatonin can repair the impaired synaptic plasticity, which might promote the functional recovery after spi-nal cord injury.

Objective To discuss the clinicopathologic characteristics and risk factors for lung metastasis of early-stage cervical cancer after radical hysterectomy. Methods The complete clinicopathologic data of patients with lung metastasis of cervical cancer after radical surgery from January 2008 to December 2013 admitted in Zhejiang Cancer Hospital were retrospectively analyzed by univariate and multivariate analysis. Results (1)There were 38 cases of early cervical cancer suffered from lung metastasis after radical hysterectomy during the period. The median age at diagnosis of cervical cancer was 46 years, the average lung metastasis time was 13 months after operation, 50.0%(19/38) cases occurred in the first year. Thirty-one cases were squamous cell carcinoma and 7 cases were non-squamous cell carcinoma.(2)Univariate analysis showed that age,clinical stage, manner of tumor growth, tumor grade, perineuronal invasion, para-aortic lymph node metastasis were not significant effect on postoperative lung metastasis(all P>0.05). But tumor size, histologic types, depth of stromal invasion, uterine body infiltration, lympho-vascular space invasion,pelvic lymph node metastasis, positive margin and abnormal tumor markers were significantly correlated with postoperative lung metastasis(all P<0.05). Multivariate analysis showed that only tumor size, histologic types and pelvic lymph node metastasis were independent risk factors for lung metastasis of cervical cancer(P<0.05). Conclusions Patients of early-stage cervical cancer with lung metastasis mostly occurs within 1 year after radical hysterectomy. Local large tumor lesions (tumor size>4 cm), non-squamous cell carcinoma and pelvic lymph node metastasis were more likely to have lung metastasis.

Objective To explore the interaction between warfarin and antiepileptic drugs such as carbamazepine and oxcarbazepine.Methods A 78-year-old woman suffered from warfarin resistance after initial warfarin dosing for several days.Based on her medication review,clinical pharmacist found that the warfarin resistance resulted from co-administered carbamazepine.Her warfarin dosage was increased,and the international normalized ratio (INR) increased to the target range.Another woman had been taking warfarin therapy for long time with a stable maintenance dose.She consulted clinical pharmacist for the influence of co-administered oxcarbazepine on warfarin.The patient was advised to maintain the dose and monitor her INR more closely.Her INR did not fluctuate.Results Carbamazepine induced warfarin metabolism.As a result,the patient needed increased dosage of warfarin to maintain the INR in the therapeutic target range.Oxcarbazepine does not induce liver enzymes,and therefore the INR did not fluctuate.Conclusion Carbamazepine may reduce the efficacy of warfarin.Oxcarbazepine offers a clinical advantage over carbamazepine,especially when co-administration of warfarin is required.

ObjectiveTo examine the effects of temsirolimus, an inhibitor of mammalian target of rapamycin, on bladder cancer cell lines T24 and BIU-87 in vitro and in vivo for purpose of evaluating the probability of mTOR targeted therapy for bladder cancer.MethodsAfter being treated by a different concentration of temsirolimus, T24 and BIU-87 cells were tested by MTT assay for cell proliferation activity.Cell cycle and apoptosis analysis were performed with flow cytometer. Wound scratch assay was used for cell migration activity and transwell motility assay. Western blot analysis was used to test the mTOR phosphorylation. Subcutaneous inoculation of 6-week-old nude mice was performed using 1 × 106 T24 cells in 50％ matrigel for both control (n = 10) and temsirolimus (n = 10) groups. The volume of tumors was examined and then the expression of Ki-67 was detected by immunohistochemistry.ResultsTemsirolimus significantly inhibited proliferation of T24 and BIU-87 cells in a dose- and time-dependent manner. After administration of temsirolimus on T24 and BIU-87 cell lines for 24 h, the rate of wound healing in 0 nmol/L groups were (88.9 ± 14. 1 ) ％ and ( 83.6 ± 16.3)％ , which were higher than in the 5 nmol/L groups, which were (42.7 ± 11.6) ％ and ( 36.9 ± 9.7 ) ％ ( P ＜ 0.05 ). In the transwell motility assay, the number of cells in the 0 nmol/L group was 26.5 ± 5.8 and 28.2 ± 4.6, which was higher than in the 5 nmol/L group ( 19.0 ±3. 8 and 21.3 ± 5.1, respectively) (P ＜ 0. 05). When temsirolimus was administered on T24 and BIU-87 cell lines for 48 h the percentages of cells delayed in phase G0/G1 in 5 nmol/L group were ( 77.46 ±6.11)％ and (73. 39 ± 4. 94)％ respectively, and higher than in the 0 nmol/L group, which were (65.99 ±5.01 )％ 、(60.15 ±3.98)％ (P ＜0.05). There was no statistically significant difference in the apoptosis rate between the two groups (P ＞ 0.05 ). In Western blot analysis, the ratios of p-mTOR/β-actin were 0.92 ±0.09 and 1.01 ± 0.08 in 0 nmol/L group, and higher than in the 5 nmol/L group (0.47 ±0.05、0.04 ±0. 01 ) (P ＜ 0.05 ). After administration of temsirolimus for 21 days, the tumor volume in nude mice in the control group were 351.1 ± 139.9 mm3 , which was larger than 351.1 ± 139.9 mm3 in the temsirolimus group ( P ＜ 0.05 ). The positive rate of Ki-67 expression was ( 67.3 ± 8.4 ) ％ in the control group, which was higher than in the temsirolimus group ( 35.5 ± 6.7 ) ％ ( P ＜ 0.05 ).ConclusionsThis study provides in vitro and in vivo evidence that temsirolimus may inhibit the viability of bladder cancer cells and temsirolimus could be exploited as a potential therapeutic strategy in bladder cancer.
