Objective To evaluate the therapeutic effects of three-dimensional conformal radiation therapy (3DCRT) in combination with transcatheter arterial chemoembolization (TACE) for stage Ⅱ primary liver cancer. Methods Eighty-one patients were retrospectively analyzed, including 36 received 3DCRT combined with TACE (Group A) and 45 received TACE alone (Group B). The short-term therapeutic effects and 1-, 2-, 3-year survival rates, average survival time of the dead patients, and side effects were compared between the two groups. Results The follow-up rate was 100%. The numbers of patients finished 1-, 2- and 3-year follow-up were 55,19 and 6,respectively. The reponse rates were 72% in group A, and 60% in group B, which were not significant different (χ~2= 1.32, P > 0.05). The 1-, 2- and 3-year survival rates of the dead patients were 83%, 63% and 25% in group A and 75%, 37% and 8% in group B. The corresponding average survival time was 21 months and 16 months, respectively. The differences of 2- and 3-year survival rates were significant between group A and B. (χ~2= 4.87, P < 0. 05 ). The incidence and se-verity of side effects did not differ significantly between the two groups. Conclusions In patients with stage Ⅱ primary liver cancer, 3DCRT combined with TACE, being more effective than TACE alone, can prolong the long-term survival without increasing the toxicities.

Objective:To study the effects of the overexpression of hsa-miR-202 on the proliferation and molecular mechanism of lung cancer A549 cells. Methods:A sequence of hsa-miR-202 with ppG/miR/eGFP/Blasitidin pasmid was directionally connected and a eukaryotic expression vector pmiR-202 of the target hsa-miR-202 gene was constructed. pmiR-202 was transtected to A549 cell with Lipofectamine 2000. The WST assay was used to detect the cell proliferation rate, and RT-PCR was used to detect the relative gene expression levels. Western blot analysis was used to detect the IL-10 protein expression levels. The interaction between miR-202 and IL-10 was examined using a luciferase reporter assay. Results:The design from the DNA sequencing results shows that a eukaryot-ic expression vector of miR-202 was successfully constructed. The proliferation inhibition rates of A549 cells by Pmir-202 were 12%, 38%, and 52%. The differences in the treatment group compared with the blank control and negative control groups were statistically significant. The RT-PCR results showed that the relative expression levels of miR-202 increased after transfection with pmiR-202. Over-expression of miR-202 can downregulate the relative gene and protein expression levels of IL-10, and the relative levels were 25%and 0.75, respectively. Compared with the blank control and the negative control groups, the difference was statistically significant (P<0.05). The fluorescent activity was reduced when transfection was performed with miR-202 mimics, and IL-10-3'UTR plasmid was cloned. Conclusion: pmiR-202 effectively inhibited the proliferation of A549 cells and exhibited a time-effect relationship with miR-202 by targeted combination with IL-10 3'UTR to downregulate IL-10 expression in A549 cells.

OBJECTIVE:To establish the quality criterion for Qingning capsules.METHODS:Rhizpma cyperi,pericarpium citri reticulatae in Qingning capsules were identified by TLC,The content of hyperoside was determined by HPLC.RESULTS:The TLC revealed clear spots in diagnostic characteristics.Hyperoside showed good linear relationship in the range of 0.3～1.5?g(r=0.999 3),with a recovery rate of 100.2%(RSD=1.11%).CONCLUSION:The quality of Qingning capsules could be controlled.

Fanconi anemia (FA) is an rare autosomal recessive inherited disease which manifests progressive marrow failure, congenital bone malformation, high risk to cancers and so on. Chromatin of FA cells display auto-instability and high hypersensitivity to interstrand DNA cross-links such as mitomycin C. As normally FA develop into acute myeloid leukemia easily, it has been regarded as pre-leukemia state. Till now 11 FA genes have been found and play a role in sustaining stability of gene groups through the same mechanism. As an active connecting protein, FANCF protein play an important part in correct FA complex formation. Which makes FANCD2 single ubiquitin. Ubiquitin FANCD2 induces chromatin and BRCA1 interact, and repair injured DNA. FA gene defect makes gene group instable and increases the risk of chromatin collapse, which finally leads to acute myeloid leukemia and myelodysplastic syndrome.

Objective To investigate the effect of castration on heart function in male rabbits postinfarction congestive heart failure model. Methods 32 male 4-5 months old New Zealand rabbits were randomly assigned to ligation of first branch of left coronary artery or sham operation (sham group, n=8). 3 weeks later 20 survived MI model rabbits were randomly subjected to castration (castration group, n=10) or sham operation (MI group, n=10). Serum FT, DHEAS levels and LVEF were checked at week 0, 3 and 15. Heart diameter and left ventricular wall thickness were measured at week 15. Results The serum FT and DHEAS levels decreased significantly at week 3. In MI group and castration group serum androgen level was lower and heart weight, ventricular diameters, ventricular wall thickness corrected by body weight were higher than that in sham group at week 15. The androgen level and body weight of castration group were lower than that in MI group. But LVEF in castration group was not higher than MI group. Conclusion There was no benefit effect of castration on heart function in male rabbits postinfarction congestive heart failure model.

Objective To investigate the clinical therapeutic effect of acupuncture on pulmonary infection after acute cerebral infarction.Methods Seventy patients with pulmonary infection after acute cerebral infarction were randomly allocated to treatment and control groups, 35 cases each. The control group received routine medication and the treatment group, acupuncture in addition. Pre-treatment and post-treatment National Institutes of Health Stroke Scale (NIHSS) scores and clinical pulmonary infection scores (CPIS) were compared between the two groups. The correlation between the NIHSS score and the CPIS score was observed.Results There were statistically significant pre-/post-treatment differences in the NIHSS score and the CPIS score in the two groups (P<0.05,P<0.01). There were statistically significant post-treatment differences in the NIHSS score and the CPIS score between the treatment and control groups (P<0.05). The correlation between the NIHSS score and the CPIS score was low in the treatment group after treatment (r=0.417,P<0.05).Conclusions Acupuncture plus medication is an effective way to treat pulmonary infection after acute cerebral infarction. It can improve the NIHSS score and the CPIS score in the patients.

Objective To research the brain hemodynamic changes in hyperacute cerebral infarction. Methods Focal cerebral ischemia models were presented in 42 healthy New Zealand rabbits by obstructing the unilateral middle cerebral artery with modified O’Brein method. Dynamic scans with intravenous bolus injection of contrast were performed at 0.5, 1, 2, 3, 4, 6h separately after operation by Siemens Somatom Plus 4 Power spiral CT scanner. Then data were input into Siemens Magic View 50 workstation and processed with perfusion CT/VA 10B system. Six cerebral blood functional perfusion maps were obtained. rCBF, rCBV, rTP, rTS of bilateral symmetric interesting regions were calculated. Results Between 0.5-6 hours after operation, the rCBF and rCBV of ischemic cores and peri-ischemic areas decreased subsequently along with times of ischemia developing. rTP、rTS of cores increased at first, then decreased to 0. rTP, rTS of peri-ischemic areas prolonged at all times. Conclusion The ischemic degree, perfusion state of ischemic tissues in brain can be estimated by hemodynamic parameters, which provide useful information for the diagnosis, therapy and prognosis of hyperacute cerebral infarction.
