Objective To evaluate the safety and local control rate and short term survival status of the treatment for primary liver cancer by microwave ablation.Methods From January 2006 to January 2014,a total of 209 lesions in which the average diameter was 3.92 cm in 187 patients was performed the microwave ablation therapy.There were 12 lessions adjacent to lung,diaphragm,abdominal wall,stomach,colon and gallbladder area. Enhanced CT examination was performed one month after ablation and the imaging data,liver function,AFP level and quality of life were followed up every three month to evaluate the effectiveness.Results 88.99 percent of le-sions achieved complete elimination after an average 1.35 times ablation.The completed elimination ratio for small lesions less than 3 cm was up to 100%.Local tumor progression occurred in 23 lesions.Seventheen patients had mild complications.The slight complication rate was about 5.82%.Death and other serious complications did not occur in this study.Conclusion Microwave ablation is safe and feasible for the lesions of liver cancer with live cancer less than 5 cm,which is located in the special dangerous area of liver cancer.Microwave ablation can significantly prolong the survival time of patients,especially for small HCC patients with <3cm.

Objective To explore the effect of palliative care on dyspnea and negative emotions in patients with lung cancer. Methods According to admission sequence, 100 lung cancer patients with dyspnea received palliative care both for 2 weeks. The differences of dyspnea and negative emotions before and after intervention were observed. Result After the intervention, the degree of dyspnea and negative emotions were significantly lower than that before (P<0.05). Conclusion The palliative care not only makes lung cancer patients physiologically and psychologically happy , but also lowers the level of anxiety and negative emotions , relieves dyspnea, and thus improves the quality of life.

Objective To evaluate the endocrine glands derived VEGF (EG-VEGF) influence on growth, migration and apoptosis of pancreatic cancer cells MiaPaCa Ⅱ. Methods MiaPaCa Ⅱ were treated by 100,200 ng/ml EG-VEGF for 24, 48, 72, 96 h, and MTT assay was used to determine the proliferation; and cell scratch experiment was used to investigate the percentage of cell migration distance, flow cytometry was used to measure the apoptosis of the cancer cells. Results After MiaPaCa Ⅱ cells were treated by 0, 100,200 ng/ml EG-VEGF for 72 h, the proliferation of MiaPaCa Ⅱ was 0. 253 ± 0. 012 , 0. 374 ± 0.013,0. 383 ±0.015, respectively EG-VEGF could significantly promote the proliferation of MiaPaCa Ⅱ ( P ＜ 0. 05 ). After MiaPaCa Ⅱ cells were treated by 0, 100 ng/ml EG-VEGF for 24 h, the percentage of cell migration distance was (27.40 ± 3.45 ) % and ( 13.21 ±4.65 ) % ,respectively with statistical difference ( P ＜ 0.05 ), EG-VEGF could significantly promote the migration ability of MiaPaCa Ⅱ cells and inhibite the apoptosis. Conclusions After EG-VEGF treatment, the growth and migration ability of MiaPaCa Ⅱ cells increases, apoptosis decreases.

Objective To investigate the clinical effects of autologous tumor immune cells (DC-CIK)assisted interventional therapy in the treatment of advanced primary liver cancer.Methods Totally 76 patients with advanced primary liver cancer were divided into 2 groups with 38 cases in each group by random number table method.The control group were merely treated with interventional therapy while the ob-servation group were treated with autologous DC-CIK cell assisted interventional therapy.The short-term curative effect,adverse reactions,liver function indexes before and after treatment,alpha fetal protein (AFP)and changes of immune function were compared between the 2 groups. Results There was no statistically significant difference in short-term curative effect and incidence of adverse reactions between the 2 groups (P >0.05).After treatment,the levels of AST,ALT and AFP in the observation group [(30.4 ±6.0)u/L,(45.2 ±3.8)u/L,(168.5 ± 49.3)mg/L]were significantly lower than those in the control group [(65.1 ±6.3)u/L,(61.8 ±5.3)u/L,(315.2 ±39.5)mg/L],and the differences were statistically significant (P <0.05).After treatment,CD3 +,CD4 + and CD4 +/CD8 + in the observation group were significantly higher than those in the control group (P <0.05).Conclusion Autologous DC-CIK cell assisted interventional therapy can sig-nificantly improve the liver function of patients with advanced primary liver cancer,and it can reduce the level of tumor marker AFP and sig-nificantly improve the immune function of patients.

Objective To investigate the anti-apoptosis effects of EG-VEGF on pancreatic cancer cell MiaPaCa and its molecular mechanism. Methods The cells were treated with 50, 100, 200 ng/ml EG-VEGF. Flow cytometry was used to determine the apoptosis. The expression of p42/44MAPK, STAT3 protein and the phosphorylation, and anti-apoptosis protein Mcl-1 was evaluated by Western blot. Non-specific G protein-coupled receptor antagonist PTX, Rsa/ERK signal transduction blockade PD98059, JAK/STAT3 signal transduction blockade AG490 were used to treat the cells for 1 h, and the change of Mcl-1 protein was observed. Results After treated with 50 ng/ml EG-VEGF, the apoptosis rate of MiaPaCa was decreased from (28.4 ±4.6)% to (13.21 ±4.65)% (P<0.05) ; the phosphorylation of p42/44MAPK increased by 1.735 ± 0.019 folds; the phosphorylation of STAT3 increased by 21.810 ± 0.052 folds; the expression of Mcl-1 protein increased by 3.460 ±0.002 folds when compared with that of control group,and the difference was statistically significant (P < 0.05 ). But the degree of phosphorylation and the expression of Mcl-1 were not further increased with 100, 200 ng/ml EG VEGF treatment. After PTX pre-treatment, the increase of Mcl-1 protein expression was completely inhibited, and after PD98059, AG490 pre-treatment, the increase of Mcl-1 expression was inhibited to 52% and 68%. Conclusions EG-VEGF can inhibit MiaPaCa cell from apoptosis,and the mechanism may be related with activation of Ras MAPK and JAK STAT3 signal transduction pathway and up-regulation of Mcl-1.

Objective: To study the relationship between Framingham risk score for coronary artery disease (CAD) and cognitive function in healthy community elders.
Methods: A total of 276 healthy community elders were evaluated by Framingham score to predict the risk for suffering from CAD in 10 years. The subjects were divided into 3 groups. High risk group (the risk > 20%), n=46, Mid risk group (the risk at 10%-20%), n=76 and Low risk group (the risk < 10%), n=154. The cognitive function was measured by mini-mental state examination (MMSE) and China adult intelligence scale (CISA). The differences of cognitive function levels to 3 CAD risk groups were studied.
Results: With the increased CAD incidence from Low risk, Mid risk to High risk groups, the MMSE score reduced accordingly (26.9 ± 1.45) vs (24.3 ± 1.53) vs (22.2 ± 1.43), P=0.014. Pearson analysis presented that MMSE score was negatively related to Framingham risk score (r=-0.213, P<0.001). There were several elements of cognitive function related to Framingham risk score including MMSE score, question answering, grid filling, oral arithmetic and word distinguishing (r=-0.247), (r=-0.167), (r=-0.132), (r=-0.152) and (r-0.256), all P<0.05.
Conclusion: CAD risk level was negatively related to cognitive function, the higher Framingham risk score resulted in the lower cognitive function in healthy community elder subjects.

Objective To identify the GNAS gene mutation resulting in pseudohypoparathyroidism type Ⅰa (PHP-Ⅰa) in one patient. Methods The clinical data of a patient with pseudohypoparathyroidism type Ⅰa was retrospectively analyzed. All the 13 exons of GNAS were sequenced using Sanger method for the patient and the parents. The distribution of suspected causal mutation was screened in 478 healthy controls. To clarify the origin of the mutation, we performed targeted high-depth sequencing of GNAS exon harboring the mutation for the patient and the parents. Results The clinical data of the patient with the laboratory results of hypocalcaemia, hyperphosphataemia, elevated serum PTH, together with the features of AHO, conformed to the characterization of PHP-Ⅰa. The sequencing of GNAS exons identified a missense mutation (c.479G>C, p.R160P) located at exon 6 in the patient, which was absent in DNA of the parents. The mutation was not reported previously and was not found in the 478 healthy controls. We obtained about 8000-fold coverage from high-depth sequencing of DNA from peripheral blood of the patient and the parents. The disease-associated allele C identified in the patient was not observed in the parents. The number of reads with G allele (3984 reads) was roughly equal to that of C allele (4019 reads) from the targeted reanalysis of DNA of the patient. The results from high-depth sequencing indicated a de novo mutation in maternal germ cells. Conclusions We identified a new GNAS gene mutation (c.479G>C, p.R160P) caused PHP-Ia in a patient. Our results suggested the mutation was a maternal germline de novo mutation.

Objective To evaluate the difference between CT and CT/MR DWI images for gross tumor volume (GTV) delineation in precision radiotherapy for esophageal squamous cell carcinoma.Methods 20 patients with pathologically confirmed as esophageal squamous cell carcinoma were selected for target delineation.The GTV based on CT and CT/MR DWI images of the patients were delineated by six radiation oncologists.The mean,standard deviation,coefficient of variation (CV =standard deviation/mean) of GTV volume,the ratio of minimum value and maximum value (ratio =maximum value/minimum value) of the GTV volume were calculated.And the CV and ratio of the GTV by the two methods were compared.Results The biggest difference of GTV volume on CT and on CT/MR DWI images was 55.71 and 13.89 cm3 (F =12.80,P ＜ 0.05).The CV on CT and CT/MR DWI images were 0.30 ± 0.08,0.11-±0.04 (Z =-3.92,P ＜ 0.05),and the ratio of GTV volume were 2.38 ± 0.62,1.34 ± 0.13,respectively (Z =-3.92,P ＜ 0.05).Conclusions CT/MR DWI images could display GTV more directly,which may help to increase consistency of GTV for esophageal squamous cell carcinoma delineation among different radiation oncologists.
