Objective To investigate the 5-and 10-year survival and complications of patients with stage Ⅱb cervical carcinoma treated by pre-operative photon radiotherapy (POPRT) plus brachytherapy (192Ir) and selective lymphadenectomy hysterectomy (SLH) plus intra-operative electron radiotherapy (IOERT). Methods From February 1997 to May 2007, 160 patients with stage Ⅱb cervical carcinoma were treated by POPRT of 20 Gy in 10 fractions to the whole pelvis, 192Ir brachytherapy of 14 Gy in 2fractions, followed by IOERT of 18 -20 Gy to the whole pelvis during SLH one week after. Results The follow-up rate was 98.1%. The number of patients followed-up for 5 and 10 years was 143 and 135,respectively. The 5-year overall survival rate, disease-free survival rate and local control rate of all patients were 89.4%, 86. 3% and 96. 3%, with the corresponding 10-year rates of 84.4%, 81.0% and 95.0%,respectively. The radiation-induced rectitis and cystitis were 5.0% and 0. 6%, respectivly. The rate of hydronephrosis and lower extremity edema was 6. 3% and 1.3%, respectively. Conclusions Combination of EBRT plus 192Ir brachytherapy and SLH plus IOERT could improve the survival and local control of patiens with cervical carcinoma, with only a few side effects.

Objective To study the effect on the environmental radioactivity level and the health of the residents in Shanghai when Qinshan Nuclear Power Station(QNPS) has been in normal operational condition for 17 years. Methods The field monitoring and the sampling analytical method were used for monitoring the radioactivity level in outdoor environment, drinking water, food and soil. Results The outdoor natural radiation level and the radioactivity level in the sample of the environmental media were on the normal background level. There was no distinct change in the environmental radiation level of Jinshan Area when QNPS was in normal operational condition. The radioactivity level in the environmental media was far lower than the limit values specified by the national standard GB. The effective dose of the outdoor natural external exposure for the residents is about 0.102 mSv/a and the effective dose of the internal exposure from the artificial radionuclides 90Sr and 137Cs in food for the residents is about 0.488 μSv/a. Conclusions There is no effect of the radioactive contamination on the environmental radioactivity level and the health of the residents in Shanghai when QNPS has been in normal operational condition for 17 years.

This study is to investigate the effect of total flavonoids of Uygur medicine bugloss (BTF) on rats with myocardial ischemia/reperfusion injury, and to explore the mechanisms by which it acts. Left anterior descending (LAD) coronary artery in rats was occluded for 30 min followed by 4 h reperfusion. Meanwhile, BTF dissolved in saline was administered intraperitoneally at dosage of 10, 30 and 50 mg x kg(-1). Electrocardiograph, infarction index, serum myocardial enzymes and heart function were determined to evaluate the effect of BTF. Some other observations were carried out to explore whether inhibiting inflammation and apoptosis is involved in the mechanisms underlying BTF. Our results showed that in ischemia/reperfusion injured rats BTF could dose-dependently reduce myocardial infarction index and myocardial enzyme leakage, and enhance heart function, indicating that it possesses significant cardio protection. ELISA analysis showed that BTF could decrease the content of myocardial inflammatory cytokines such as IL-1beta, IL-6 and TNF-alpha. Western-blotting confirmed that BTF could increase the expression of anti-apoptotic protein Bcl-2 and reduce the expression of proapoptosis protein Bax. Further more, the phosphorylation level of PI3K and Akt was upregulated by BTF treatment. BTF can protect rat against myocardial ischemia/reperfusion injury. Anti-inflammation and inhibition of apoptosis through upregulating PI3K/Akt signal pathway may contribute to the protective effect of BTF.

Thirty-six healthy Sprague-Dawley male rats were used and divided randomly into a control group (group C), a medium-dose cadmium loading group (group M) and a high-dose cadmium loading group (group H). Cadmium chloride was diluted with saline to contain 0.4 mg/ml of autoclaved cadmium solution. Groups M and H were injected in the abdominal cavity with 0.5 and 1.0 mg of cadmium per kg body weight respectively, and group C with saline of the same dosage as in group H over 7 d. Six rats of each group were killed on the 4th day and 7th day after cadmium loading, respectively, and blood, testis, liver and heart were collected. Cadmium content, changes in nitric oxide and tumor necrosis factor-alpha were studied in blood and the tissues of testis, liver and heart. Results showed that during the entire experimental period, body weight in groups M and H decreased significantly as compared with that in group C; cadmium concentration increased significantly in testis, heart and liver of groups M and H, and rose with increased dosage and time of cadmium loading; there was no obvious difference in plasma nitric oxide between groups M and C, though nitric oxide was higher in group M than in group C. Nitric oxide in group H was significantly superior to that in group C. Plasma tumor necrosis factor-alpha was markedly higher in groups M and H than in group C. Nitric oxide contents in the rat s testis, liver and heart homogenates with cadmium loading were higher than those in group C or significantly superior to group C. The same changes in tumor necrosis factor-alpha in the tissue homogenates of the testis and heart were found, but no obvious difference in tumor necrosis factor-alpha in the liver between the three groups was observed. It is suggested that the massive release of nitric oxide and tumor necrosis factor-alpha induced by cadmium loading may play an important role in the induction of malfunction of multiple systems or organs in rats.

0.05).The effective rates of patients with recurrence or metastasis were respectively 92%(12/13) and 7/9.The rate of acute radiation reaction of the rectum between the treatment group and control group were respectively 46%(13/28)and 80%(24/30),with a significant difference(P0.05),while the rate of severe bone marrow depression between two groups showed a significant difference(0 and 13%,P 0.05).Conclusion The therapeutic effect of 3DCRT is similar to that of traditional radiotherapy in the treatment of cervical carcinoma,but the former treatment method has a lower rate of acute complications.

OBJECTIVETo study the the relationship between lymphatic vessel density (LVD) and distal intramural spread (DIS), and evaluate the value of LVD in determining the length of distal resection in low rectal cancer.

METHODSNinety-two samples from patients undergone curative resection of low rectal cancer were studied. DIS was detected by HE stain. LVD was examined by immunohisto-chemical LYVE-1 (lymphatic vessel endothelial hyaluronan receptor). The association of LVD with DIS and other clinicopathological factors were examined.

RESULTSDIS (range 0.1-2.4 cm, mean 0.31 cm) was present in 44(47.8%) patients with low rectal cancer, including 23(52.3%) cases with cancer emboli in lymphatic vessels. LVD of peritumoral lesion was significantly higher than that of intratumoral lesion. LVD of DIS subgroup was significantly higher than that of non-DIS subgroup. Positive correlation was found by rank correlation test between the length of DIS and the LVD at peritumor tissue in DIS group (n=44, r=0.755, P<0.01). LVD was also positively correlated with the infiltration extent, lymphatic invasion and lymph node metastasis.

CONCLUSIONSLymphangiogenesis plays an important role in rectal cancer metastasis and cancer emboli in lymphatic vessels is the most common modality of DIS. The LVD is positively correlated with DIS, which may be helpful to determine the distal clearance length of rectal cancer.
