Objective To compared intensity modulated radiation therapy (IMRT) with conventional radiotherapy(CR) for the left side breast cancer after breast-conserving surgery in regard to the homogeneity of dose in the target area, cardiac dose and irradiation volume in the target area. Methods Thirty-eight patients received inverse planning of IMRT with dynamic multi-leaf collimation (dMLC). Prescription dose was 46Gy in breast volume with X-ray, and added electron boost dose was 14Gy in the tumor bed, with a total dose of 60Gy. Clinical target volume(CTV) and heart were evaluated with dose-volume histograms(DVH) in the two plans, with the t test taken with SPSS 11.0. Results Average received dose of 95% breast volume(D 95) was (4541?34),(4517?62)cGy, volume of 105% of dose prescription(V 105%) was 17.5%?17.6%,29.4%?26.3%, while V 110% was 0.3%?0.8%,3.7%?8.2% with IMRT and CR, respectively. Received 30Gy by the heart(V 30) was 4.6%?4.3%,18.8%?12.2%(P

Objective To explore the method for early diagnosis of masked polycythemia vera (mPV) by comparing and analyzing the features of mPV and polycythemia vera (PV). Methods A total of 200 newly diagnosed male patients were collected based on diagnostic criteria, including 100 cases of PV and 100 cases of mPV. Erythropoietin (EPO), neutrophil alkaline phosphatase (NAP) score, bone marrow biopsy (BMB), and JAK2 V617F mutation were evaluated in all cases. After 6 months, hemoglobin (Hb) and JAK2 V617F mutation load were detected in patients without special treatment in two groups during follow-up. Results EPO, NAP score, BMB hematopoietic volume and the number of megakaryocyte had no statistical differences between PV group and mPV group [(3.4 ± 0.7) U/ml vs. (3.2±0.6) U/ml, (276±20) score vs. (278±21) score, (78±10) % vs. (76±9) %, (53±6) vs. (51±5), respectively], while JAK2 V617F mutation load in PV group was higher than that in mPV group[(89.2±9.4) % vs. (78.1±8.6) %, P<0.05]. In mPV patients without special treatment, Hb ≥185 g/L was found in 37 patients after 6 months, and the level of Hb and JAK2 V617F mutation load in these 37 patients reached (194±8) g/L and (90.7±9.1) %, respectively. Conclusions There is no significant difference in EPO, NAP score and BMB between PV and mPV, but the JAK2 V617F mutation load is different. In mPV patients without special treatment, Hb level can reach the typical PV diagnostic criteria after 6 months, meanwhile, JAK2 V617F mutation load is also increased.

Objective To study the diagnostic value of coronary disease with 16-slice spiral CT.Methods 35 patients with coronary heart disease(CHD) were divided into two groups according to the risk rate of CHD:group 1 with acute coronary artery syndrome(ACS)(including acute myocardial infarction,AMI;unstable angina,UA);group 2 with stable angina(SA).They were studied by 16-slice spiral CT(retrospectively ECG-gating,0.5 s ratation),the images were reconstructed by survey methods to display the coronary artery atherosclerosis plaques,then to evaluate the nature of plaques by detecting CT value of plaque(using the standard of the CT value of the coronary artery atherosclerosis plaque of Schroeder)and to analyze the degree of the stenosis of coronary artery caused by the different type of plaque.Results There were 19 soft plaqes,11 middle plaques and 7 calcification plaques in ACS group;3 soft plaqes,3 middle plaques and 11 calcification plaques in SA group.There was a positive relation between soft plaqes and middle plaques with the risk rate of CHD,especially soft plaque(P

Objective To analyze the dosimetfic benefits, clinical effect and side-respond of whole breast using intensity modulated radiotherapy for early breast cancer after conservative surgery. Methods From Oct.2004 to Aug. 2005,103 patients received the whole breast intensity modulated radiation therapy (IMRT). A dosimetric comparison of IMRT with conventional radiotherapy (CR) was performed on each patient. The cosmetic results, clinical effect and side-respond were observed. Results The average volume proportion of 95% and 107% prescribed dose was 95.8% ± 4.90% and 84.0% ± 20.7% (t = 9.60, P < 0.01) with IMRT and CR in clinical target volume, respectively. The V20 (lung volume of aceepted> 20 Gy/all lung volume × 100%) of the ipsilateral lung were 15.70% ± 4.64% and 23. 11% ± 7.88% (t = - 13.3, P < 0.01). The V30of the heart were 4.44% ±3.93% and 15.55% ± 10.89%(t = - 11.3, P< 0.01) with IMRT and CR respectively for sixty-three left side breast cancer patients. The 1- and 2-year excellent rate of good cosmetic outcome was both 100%. The 1-, 2- and 3-year local control rate was 99% ,99% and 98% ,respectively. The 1-, 2- and 3-year disease-free survival rate was 99% ,99% and 96% ,respectively. The Grade 1 and 2 acute radiation skin reaction rate was 95.1% and 4.9%, respectively. Conclusion Compared with conventional radiotherapy, IMRT improves dose distribution of CTV and reduce the dose of normal tissue around CTV;but with better clinical effects and lower side-respond for early breast cancer patients after breast conservative surgery.

Objective To study the correlation between sleep quality and anxiety in patients with chronic kidney diseases (CKD).Method Toally 118 patients with CKD were investigated with Pittsburgh sleep quality index (PSQI) and self-rating anxiety scale (SAS).Results About 75.42％ (89/118) patients had poor quality of sleep.The scores by PSQI and the dimensions were higher than those of the norms (all P＜0.05),but the total scores by PSQI and the factors of sleep quality,time of falling sleep,duration of sleep,use of hypnosis drugs were all significantly lower than those of the insomnia group (all P＜0.01).35.59％ (42/118) of the patients had anxiety and the score of SAS was significantly higher than that of the national norm (P＜0.01).The total scores of PSQI,sleep quality,sleep time,sleeping time,sleep disorder,daytime function were positively related to the score of SAS (P＜0.01).Conclusions The quality of sleep is poor in the CKD patients and there is a positive correlation between the quality of sleep and the anxiety.It is necessary to strengthen the knowledge-related health education and to provide emotional support and individualized nursing services for CKD patients so as to relieve their anxiety and improve their sleep quality.

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.

Objective:To analyze the use status of antibiotics and the resistance of clinic isolate bacteria against the commonly used antibiotics before and after the intervention. Methods:Using the information retrieval systems, the consumption of antibiotics in the inpatients during the 1st quarter of 2012(before the intervention) and the same period of 2013(after the intervention) was com-pared. According to the defined daily dose ( DDDs) , the antibiotics were ranked, and the resistance rate against the commonly used antibiotics was analyzed. Results:Compared with the top ten before the intervention, the top ten after the intervention was changed sig-nificantly, however, cephalosporins was still the main species. After the intervention, the overall decline in DDDs was significant, the separation rate and distribution of bacteria remained stable. ESBLs enzyme production rate of Enterobacteriaceae Escherichia coli was re-duced by 7. 61%, and that of Klebsiella pneumoniae was reduced by 1. 34%, and the resistance rate against the commonly used antibi-otics was in an overall downward trend. The resistance rate of Gram-positive staphylococci against the commonly used antibiotics was de-creased, while that of Gram-positive enterococci showed notable difference. Conclusion:The DDDs of antibiotics and bacterial resist-ance rate are in an overall downward trend in our hospital after the intervention;however, there is still exception. Therefore, the clini-cal antimicrobial susceptibility tests should be performed as soon as possible to help the choice of antibiotics.
