BACKGROUND:Immortalized cervical epithelial cels H8 can become cancerous under the induction of carcinogenic agent, and may cause cervical cancer when there is a cofactor interaction. However, there is stil a lack of effective intervention for female patients with precancerous lesions, and this treatment is blank in the clinic. OBJECTIVE: To explore the effects and mechanism of astragalus injection on apoptosis of human immortalizedcervical epithelial cels H8. METHODS: This study contained two groups: astragalus drug group and the blank control group. (1) Enzyme linked immunosorbent assay (ELISA) was used to detect DNA fragments of apoptotic H8 after astragalus injection. (2) Enzyme-labeling instrument was used to analyze the changes in caspase-3 and caspase-9 activities a fter astragalus injection. (3) Western blot assay was used to detect the protein expression changes of caspase-3, caspase-9 and PARP in H8 cels after astragalus injection. RESULTS AND CONCLUSION: (1) ELISA results showed that at 0, 6, 12 and 24 hours after 20 g/L astragalus injection, DNA fragments were gradualy increased with time prolonged in a time-dependent effect (P < 0.05). (2) Enzyme-labeling instrument demonstrated that at 0, 6, 12 and 24 hours after 20 g/L astragalus injection, caspase-3 and caspase-9 activities increased in a time-dependent manner (P < 0.05). (3) At 0, 6, 12 and 24 hours after 20 g/L astragalus injection, the expression of cleaved caspase-3 and cleaved caspase-9 were gradualy increased in H8 cels (P < 0.05). Cleaved PARP protein expression was gradualy decreased (P < 0.05). These findings indicate that astragalus injection could obviously induce H8 apoptosis, which may be associated with the upregulated protein expression of caspase-3 and caspase-9.

BACKGROUNDTo investigate the relationship between expression of fragile histidine triad gene protein, Fhit, and clinicopathological characteristics of human lung cancer.
METHODSFhit protein expression was detected in 92 cases of formalin-fixed, paraffin-embedded human lung cancer by citrate-microwave-SP immunohistochemical method, of which 52 were non-small cell cancer (NSCLC) and 40 small cell cancer (SCLC). Its relationship to histological grade, lymph node metastasis and histological classification were analysed.
RESULTSThe loss of Fhit protein expression were found in 62.0% (57/92) and 4.3% (4/92) of cancer tissue and normal lung tissue, respectively and there was a significant difference in the expression of Fhit protein between cancer and normal tissue (P=0.000). 53.8% (28/52) of the cases of NSCLC showed a marked loss or absence of Fhit expression, 46.2% (24/52) of cases were negative, 7.7% (4/52) showed a higher expression and 38.5% (20/52) equal to the level of Fhit expression compared with the matched normal tissues. The loss of Fhit expression was closely related to histological grade (P=0.003), to lymph node metastasis (P=0.029), and to histological classification of the cases (P=0.003). There was a significant difference between grade I+II (38.2%; 13/34) and grade III cancer (83.3%; 15/18), between cancers with lymph node metastasis (70.8%; 17/24) and those without (39.3%; 11/28), and between squamous cell carcinoma ( 68.6%; 24/35) and adenocarcinoma (23.5%; 4/17). The loss of Fhit protein expression was found in 33 of 40 cases of SCLC (82.5%) and the remainder 7 cases (17.5%) showed the same quantity of expression of Fhit, compared with the normal bronchial mucosa.
CONCLUSIONSThe expression of Fhit protein may be associated with the decreasing differentiation, lymph node metastasis and histological classification in NSCLC, and be corresponding to the occurrence and evolution of SCLC. These results suggest that the decreased Fhit expression plays an important role in the development and progression of the tumor, and thus may become a new prognostic marker in human lung cancer.

Objective To assess right ventricular systolic function in normal subjects and patients with pulmonary arterial hypertension (PAH) by using 2-dimensional strain (2DS) and tissue Doppler imaging(TDI), and to investigate the feasibility of 2DS for quantitative assessment of myocardial longitudinal systolic function. Methods Longitudinal peak systolic velocity (V), peak systolic strain(ε), peak systolic strain rate(SRS) were measured in right ventricular free wall for basal,mid and apical segment in 42 patients with PAH and 31 healthy controls by 2DS and TDI from the apical 4-chamber view and compared between 2DS and TDI. Results ①Compared with controls,ε and SRS of the mid segment of the right ventricular free wall by TDI were significantly reduced in patients with PAH (P<0.05),but these of the basal and apical segment were normal (P>0.05). ε and SRS of all segments by 2DS were markedly reduced in patients with PAH (all P<0.05), V of all segments by TDI and 2DS were not decreased (P>0.05). ②In normal subjects,values(V,ε,SRS) of basal and apical segment of right ventricular free wall measured by 2DS were significantly different from those by TDI (P<0.05), Values of mid segment by 2DS and TDI were not significantly different (P>0.05); In patients with PAH, values (V, ε, SRS) of apical segment of right ventricular free wall by 2DS were significantly different from those by TDI,values of basal and mid segment by 2DS and TDI were not significantly different. ③ There were good correlations between 2DS and TDI in patients with PAH (r = 0.406~0.760, P<0.05 for all). Conclusions Right ventricular longitudinal systolic function in patients with PAH was decreased, 2DS is more accurate and objective than TDI in assessment of right ventricular longitudinal systolic function.

To evaluate the feasibility of real-time myocardial contrast echocardiography (RTMCE) by quantitative analysis of myocardial perfusion in rabbits, transthoracic RTMCE was performed in 10 healthy rabbits by using continuous infusion of SonoVue into the auricular vein. The short axis view at the papillary muscle level was obtained. The duration of the time that the contrast took to appear in right heart, left heart and myocardium was recorded. The regional myocardial signal intensity (SI) versus refilling time plots were fitted to an exponential function: y(t) =A(1-e(-beta(t-t0))) + C, where y is SI at any given time, A is the SI plateau that reflects myocardial blood volume, and beta is the slope of the refilling curve that reflects myocardial microbubble velocity. The A, beta and Axbeta values at different infusion rate of SonoVue were analyzed and the A, beta and Axbeta values in each segment in the short axis view at the papillary muscle level were compared. All the animal experiments were successful and high-quality images were obtained. The best intravenous infusion rate for SonoVue was 30 mL/h. The contrast appeared in right heart, left heart and myocardium at 7.5+/-2.2 s, 9.1+/-2.4 s and 12.2+/-1.6 s respectively. After 16.6+/-2.3s, myocardial opacification reached a steady state. The mean A, beta and Axbeta value in the short axis view at the papillary muscle level were 9.8+/-3.0 dB, 1.4+/-0.5 s(-1) and 13.5+/-3.6 dBxs(-1) respectively. A, beta and Axbeta values showed no significant differences among 6 segments. It was suggested that RTMCE was feasible for quantitative analysis of myocardial perfusion in rabbits. It provides a non-invasive method to evaluate the myocardial perfusion in rabbit disease models.

Quantification of right ventricular (RV) volume and function remains a challenge because of RV complex geometry by conventional echocardiography. The purpose of this study was to assess RV global longitudinal function in patients with tetralogy of Fallot (TOF) by 2-dimensional ultrasound speckle tracking imaging (STI). Thirty-eight patients with TOF were enrolled in this study and divided into child group (n=25) and adult group (n=13) according to age. Thirty-eight age- and sex-matched normal subjects were selected as control groups including child control group (n=25) and adult control group (n=13). RV global longitudinal peak systolic strain (GLS), strain rate (GLSR(s)), early diastolic strain rate (GLSR(e)) and late diastolic strain rate (GLSR(a)) were measured in all subjects by STI from the apical 4-chamber view and compared between groups. Furthermore, the main factors affecting the RV global longitudinal functional parameters were assessed. Compared with those in controls, RV GLS, GLSR(s) and GLSR(e) were significantly reduced in patients with TOF (P<0.05 for all). RV GLSR(s) was significantly decreased in adult patients with TOF as compared with that in child patients (P<0.05). There was no significant difference in RV GLS, GLSR(e) and GLSR(a) between child and adult TOF groups (P>0.05). The diameter of right ventricle, main pulmonary artery and ventricular septum defect had correlations with RV GLSR(s) (r ( 1 )=-0.490, r ( 2 )=0.580, r ( 3 )=-0.528, respectively, P<0.05 for all). Tricuspid annular plane peak systolic velocity (Sm) was the independent predictor of RV global strain and strain rate (beta(1)=0.355, P (1)=0.031, beta(2)=0.307, P (2)=0.021). RV global longitudinal function is decreased in patients with TOF, especially in adult patients. STI is a sensitive and accurate technique in RV global functional assessment.
