OBJECTIVE:To study the effects and mechanism of rapamycin on invasion and metastasis of cervical cancer HeLa cell. METHODS:HeLa cells were divided into control group and rapamycin low-dose,medium-dose and high-dose groups (10, 30,100 nmol/L). After treated for 48 h,cell viability was measured by MTT assay,and inhibitory rate was calculated;migration and invasion of cell was tested by Transwell assay. The expression of matrix metalloproteinase 2(MMP-2),MMP-9,Vimentin and E-cadherin,and phosphorylation of protein kinase B (Akt),mammalian target of rapamycin (mTOR) were detected by Western blot. RESULTS:Compared with control group,the inhibition rate of cell viability was increased in rapamycin groups(P<0.01);the number of invasion and metastasis cells decreased(P<0.01);the expression of MMP-2,MMP-9 and Vimentin were decreased (P<0.01 or P<0.05);the expression of E-cadherin was enhanced(P<0.01 or P<0.05);the phosphorylation of Akt and mTOR were reduced (P<0.01). CONCLUSIONS:Rapamycin could inhibit invasion and metastasis of HeLa cell via Akt/mTOR signal pathway.

Objective To investigate the expression of endothelin converting enzyme (ECE) mRNA in patients with acute cerebral infarction (ACI) and its clinical significance.Methods Blood samples from 40 patients with ACI (patient group) within 72 hours after the onset of ACI and 28 gender and age-matched healthy subjects (control group) were collected on admission. Plasma concentrations of endothelin-1 (ET-1) as well as the serum levels of cholesterol, triglyceride, low density lipoprotein,high density lipoprotein, apoA1, apoB, lipoprotein a and fasting plasma glucose in each sample were measured and analyzed. Additionally, semi-quantitative RT-PCR was performed to check the ECE mRNA level in the blood cells. European stroke scale (ESS) was used to evaluate ACI patients' neurological deficit on admission.Results (1) ECE mRNA could be detected in every blood sample from either patient group or control group. However, the ECE mRNA level increased significantly in the patient group compared with that in the control group (0.31?0.092 versus 0.25?0.10, t=2.46, P=0.016). (2) The plasma ET-1 concentration in patient group was also significantly higher than that of control subjects (183.27?56.63pg/ml versus 156.47?34.24 pg/ml, t=2.23, P=0.029). (3) Plasma ET-1 concentration was negatively correlated with ECE mRNA level in the control group (r=-0.452, P=0.021). However, the result in the patient group was not the same as the control group. (4) The ET-1 concentration and ECE mRNA level in the patients had histories of hypertension, diabetes mellitus and stroke were not significantly different from those in the patients without these histories. (5) No significant correlation existed between plasma ET-1 concentration and ECE mRNA level and age of the patient, ESS score, fasting plasma glucose and serum lipid. Conclusions ECE mRNA level is significantly increased in the early stage of ACI, which may be associated with the acute-phase reaction of cerebral infarction and may have deleterious effects on the development of neuronal injury. Our results suggest the protective reflection in the endothelin system of normal human body may be disturbed by the onset of ACI. The relationship between ECE mRNA level and neurological deficit degree, stroke risk factors is worthy for further study.

Objective To investigate the preventive effect of fibroblast growth factor on infection after tooth extraction among type 2 diabetes mellitus patients. Methods 76 patients with infection prevention were treated with basic fibroblast growth factor, and 90 patients in the control group(n= 324). The intervention group was treated with basic fibroblast growth factor and treated with recombinant bovine basic fibroblast growth factor gel. The routine treatment group was treated with routine rinsing liquid for disinfection to prevent infection. Follow-up observation of infection after 1 week. Results In the group of basic fibroblast growth factor, the infectious rate was 2.63%, which was not significantly lower than that of the control group. The level of white blood cells in the group treated with basic fibroblast factor was (6.67±1.08)×109/L, which was significantly lower than that of the control group. The CRP level was (90.33±12.95) mg/L, which was significantly lower than that of the control group Group level (P<0.05). The incidence of fibroblast infection was 2.7% in men and 6.38% in control group. Although there was no significant difference between the two groups, the difference in the total WBC count and CRP level between the two groups was significant different (P<0.05). The group which use of basic fibroblast growth factor, the total white blood cell count and CRP level of the infection prevention intervention group were significantly lower than the control group (P<0.05). Similar results were found in women. Conclusion Fibroblast growth factor can be used to prevent postoperative infection, and achieve satisfactory results.

Objective To investigate the effects of stress intensity and the expected duration of stress on the inhibition ability of individual responses to stress. Methods A total of 60 cases of hospitalized patients in respiratory department were selected in the study,including 31 male cases and 29 female cases. Incorporated patients were divided into the high-stress group and the low-stress group ( 30 cases in each group) according to whether the patient accepted a invasive examination or not. Then,within each group,pa-tients were further randomly sub-divided into the acute expectation group and the chronic expectation group ( 15 cases in each group) in the form of a lottery. Detection risk disclosure was conducted at 2 hours and at 24 hours before the examination. Visual analogue scale ( VAS) and stop-signal task were used to detect the level of psychological fear and the inhibition ability of individual responses to stress of each group following informing of the detection risk,and the comparative analysis was conducted afterwards. Results ( 1) The score of psychological fear in the high-stress group was significantly increased when compared to the low-stress group ((3.90±2.71) vs (0.80±1.24)),showing statistical difference (F(1,58)=30.16, P<0.01);addi-tionally,there was no statistical difference in the score of psychological fear in subjects between the acute and chronic expectation group ((2.60±2.90) vs (2.10±2.41);F(1,58)=0.785, P>0.05);meanwhile,no statisti-cal difference of the interaction between stress intensity and the expected duration of stress on the level of psychological fear (F(1,58)=0.031, P>0.05). (2) As for stop-signal task,the signal execution error rate of the high-stress group was significantly increased than that in the low-stress group ((9.40±5.80)%vs (8.30± 12.60)%),and the statistical difference was significant (P<0.01).Signal execution responses duration was obviously prolonged in the acute expectation group than that in the chronic expectation group ((677.25±201. 26)ms vs (588.24±127.10)ms),and the difference was statistically significant (P<0.05); meanwhile,stop-signal error rate at 400 ms was significantly decreased ((57.00±26.00)% vs (70.00±23.80)%),and the difference was statistically significant (P<0.05). There was no statistical significance in the interaction be-tween stress intensity and the expected duration of stress (P>0.05) . Conclusion There is no interaction be-tween the effect of the stress intensity and the expected duration of stress on the inhibition ability of individu-al responses to stress. The stress intensity is more important than the expected duration of stress to exert more important influence in the inhibition ability of individual responses to stress.
