Objective To investigate the correlation between dose volume histogram(DVH)of tumor targets and organs at risk(OAR)at CT-image based 192Ir brachytherapy and effects and complications for patients with locally advanced cervical cancer. Methods Ten patients with FIGO stage ⅢB cervical cancer received CT image-based 192Ir intracavitary brachytherapy after 54 Gy of three-dimentional four-field pelvic external beam radiotherapy and concurrent weekly cisplatin chemotherapy. Before each brachytherapy,CT images were acquired with applicators in place. Gross tumor volume(GTV), clinical target volume (CTV)and OAR were contoured and inverse treatment planning was designed and optimized by using PLATO treatment planning system. Conventional two-dimensional plans were also designed for comparison.The total intracavitary brachytherapy dose was 30 -42 Gy in 5 -7 fractions. The patients were followed, and the local control and complications were analyzed. The biologically equivalent dose(BED)and biologically equivalent dose in 2 Gy fractions(BED2)for GTV, CTV and OAR were calculated. The minimum dose in the most irradiated tissue volume 2 cm3(D2 cm3)adjacent to the applicator of the sigmoid colon, rectum,bladder and small bowel was determined from the DVH. Results The 1-year local pelvic control rate was 90% and grade 1-2 late complication of sigmoid colon and rectum was 50%. No grade 3 or more complications developed. On CT-image based planning, the BED and BED2 to 90% of the CTV(D90)were 95.50 Gy ± 7. 81 Gy and 79. 73 Gy ± 6. 57 Gy. The BED and BED2 to 90% of the GTV(D90)were 101.86 Gy ± 7.27 Gy and 84. 95 Gy ± 6. 1 Gy. The volume enclosed by 90% of prescribed dose(V90)for GTV and CTV were 92% ±4% and 87% ±7% respectively. The D2cm3 for rectum and sigmoid colon were 74. 97 Gy ±1.64 Gy and 67. 93 Gy ± 4. 30 Gy(EQD2, α/β = 3). Comparing with 2D brachytherapy plans , CT - image based planning has improved D90 and V90 for GTV and CTV with similar dose at point A and rectum reference point. Conclusions Computer tomography-image based 192Ir brachytherapy has resulted in the better dose distribution to the tumor targets with excellent tumor control and acceptable toxicity.

BACKGROUND: The occurrence and severity of acute high-altitude disease(AHAD) are determined by the speed entering the highland, the altitude of highland and seasons. The association between obesity and AHAD has not been fully investigated.OBJECTIVE: To investigate the association between obesity and acute high-altitude in people exposed rapidly to the highland.DESIGN: Comparative observation.SETTING: Department of Cardiology, General Hospital of Chinese PLA and Department of Cardiology, Tibetan General Hospital of Chinese PLA.PARTICIPANTS: The experiment was conducted at the Department of Cardiology, General Hospital of Tibetan Military Area Command of Chinese PLA in August 2006. Totally 82 Henan subjects aged 28-45 years were selected from the male workers constructing the Qinghai-Tibet Railway and their managers with acute high-altitude exposure. They had never been to the highland before, and all agreed to the detection.METHODS: ①Every subject completed the AHAD self-report questionnaire at sea level and 12 hours and 24 hours after ascending high-altitude. The items in the questionnaire included symptoms of headache, gastrointestinal symptoms,fatigue or weakness, dizziness, and insomnia. Each symptom was graded from 0-3 with 0 as no symptoms, 1 as mild symptoms, 2 as moderate symptoms, and 3 as severe symptoms and a total score of 15. A score of 4 or more could by identified as AHAD. ②The height and body mass were measured to calculate the body mass (BMI). Those with BMI≥28 kg/m2 served as the obesity group [n =39, mean age (35±8) years], and those with BMI of 18.5-23.9 kg/m2 as the normal body mass group [n =43, mean age (35±8) years]. ③Arterial blood was taken to evaluate arterial oxygen saturation (SO2), arterial oxygen pressure (PaO2) and arterial carbon dioxide pressure (PaCO2) at baseline and 24 hours after ascending high-altitude. ④The measurement data was compared by t test.MAIN OUTCOME MEASURES: BMI, vital capacity of lungs, SO2, PaO2 and PaCO2 levels of obese and normal people.RESULTS: Totally 39 obese people and 43 normal people were involved in the result analysis. ①AHAD score: No symptom was reported at sea level in all participants (scored 0), but the AHAD scores in the obesity group were significantly higher than those in normal group 12-hour and 24-hour after ascending high-altitude. ②Blood gas analysis:At sea level, there were no statistical differences in the levels of SO2, PaO2, and PaCO2 between two groups (P ＞ 0.05).But 24 hours after ascending high-altitude, SO2 and PaO2 of the obesity group were much lower than in the normal group (P＜ 0.01), and PaCO2 was significantly higher than in the normal group (P＜ 0.01).CONCLUSION: Obese men are more vulnerable to high-altitude hypoxia than people with normal body mass. Obesity is an important risk factor for the development of acute high-altitude disease.

Objective To investigate the effect of video-assisted thoracoscopic surgery( VATS) in thoracic disease,and the feasibility to carry out VATS for basic hospital. Methods The data of VATS treatment were collected to compare the differences between study group and control group,and evaluate the the feasibility to carry out VATS for basic hospital. Results The operation time was (100. 75±22. 72) min, blood loss was (54. 27±26. 21) mL,postoperative drainage was (920. 67±171. 99) mL. The postoperative complications were fewer,post-operative hospital stay was shorter,incision time was shorter(P=0. 000) and pain scores was lower(P=0. 000) in study group than that in control group. Basic hospital has the capacity to conduct this technical. Conclusion VATS is feasible to carry out in basic hospital.

Objective To investigate the effects of Krüppel like factor 4 (KLF4)on matrix metalloproteinase 9 (MMP9)ex-pression in hepatocellular carcinoma(HCC).Methods A total of 50 primary hepatocellular carcinoma samples and their correspond-ing adjacent tissues specimens were collected.The expression of KLF4 and MMP9 were detected by IHC,Western blot and qRT-PCR.After KLF4 gene was transfected into hepatocellular carcinoma cell line (HepG2 cell line),the expressions of KLF4 and MMP9 were conformed by qRT-PCR and Western blot.Migration and invasion of HepG2 cell line transfected by KLF4 were detec-ted by wound-healing assay and invasion assay.Results Compared to corresponding adjacent tissues,The expression of KLF4 was significantly lower in HCCs(P <0.05),and MMP9 expression was remarkably higher in HCCs(P <0.05).KLF4 over-expression inhibited the expression of MMP9 on the protein and mRNA levels.Wound-healing assay and invasion assay confirmed that KLF4 regulated cell invasion and migration through regulating MMP9 expression.Conclusion KLF4 showed low expression in HCCs,and MMP9 was overexpressed.Up-regulation of KLF4 could decrease the expression of MMP9 in HepG2 cell line,which inhibited inva-sion and migration.

Objective To investigate serum galectin-3 levels in patients with chronic heart failure and evaluate its clinical significance for heart failure.Methods A total of 108 chronic heart failure patients were selected.The selected patients were divided into three groups according to the classification of New York Heart Association (NYHA,from degree Ⅱ to Ⅳ).In addition,30 healthy persons were chosen as control group.All the patients received cardiac ultrasound examination.Plasma levels of N-terminal probrain natriuretic peptide (NT-proBNP),serum levels of galectin-3 and interleukin-6 (IL-6) were measured and analyzed.Results Galectin-3 levels were significantly higher in chronic heart failure patients compared with control group(P ＜ 0.05).In chronic heart failure group,the increase of serum concentration of galectin-3 was correlated with the degree of NYHA function classification.Correlation analysis showed that blood level of galectin 3 was strongly positive correlation with concentration of NT-proBNP and IL-6.There was no correlation between galectin-3 with the cause of heart failure,left ventricular diameter(LVD),and left ventricular ejection fraction (LVEF).Conclusions The levels of galectin-3 was significantly increased in chronic heart failure,and was correlated with degree of heart failure.Galectin-3 might be a new biomarker of heart failure and could provide additive value to NT-proBNP levels in the diagnosis of heart failure.
