Objective To know the levels of polychlorinated dibenzo-p-dioxins(PCDDs),polychlorinated dibenzo-p-furan (PCDFs)and polychlorinated biphenyl(PCBs)in milk and milk powder.Methods From Feb.2007 to Jun.2007,the milk and milk powder samples were collected and PCDDs,PCDFs and PCBs were extracted from the samples by Soxhlet extraction,cleaned up by FMS and quantified by HRGC-HRMS,using isotope dilution methodology.Results PCDDrFs and PCBs were detected in all samples.The mean levels of PCDD/Fs and dl-PCBs TEQ in the milk powder were 0.43 pg/g lipid(median:0.34 pg/g lipid),and in the packed milk were 3.83pg/g)lipid(median:2.04 pg/g lipid).The mean levels of PCDD/Fs and dl-PCBs TEQ in all samples were 2.13 pg/g lipid(median:0.815 pg/g lipid).The levels of PCDD/Fs and dioxin-like PCBs in the detected samples were far below the limitation of EU except of two milk samples,and the levels of PCDD/Fs and dioxin-like PCBs were higher in the packed milk than those in the milk powder.Conclusion Some of the milk and milk powder in the investigated city has been polluted by polychlorinated dibenzo-p-dioxins(PCDDs),polychlorinated dibenzo-p-furan(PCDFs)and polychlorinated biphenyl(PCBs).

OBJECTIVETo investigate clinical outcomes of Kirschner wire as blocking screws combined with interlocking intramedullary nail internal fixation in treating tibial metaphyseal fractures (AO 43A).

METHODSFrom March 2011 to June 2012, 9 patients with tibial metaphyseal fractures were treated with blocking screws Kirschner wire combined with interlocking intramedullary nail, including 7 males and 2 females aged from 23 to 54 years old with an average of 37.4. Postoperative complications, X-ray were observed, AOFAS scoring were used to evaluate function after operation at 12 weeks.

RESULTSAll patients were followed up from 6 to 40 weeks (mean 20.1), and healed at stage I. No serious swelling, infection and skin necrosis occurred. No fracture instability and displacement appeaered at 4 and 8 week after operation. AOFAS score was (95.2±4.6) at 12 weeks after operation and 7 patients gained excellent result and 2 patients good.

CONCLUSIONKirschner wire as blocking screws with interlocking intramedullary nail for treatment of tibial metaphyseal fractures can fix well and perform simply.

AIM:To report the safty and efficiency of intravitreal injection of bevacizumab (Avastin) in patients with macular edema (ME) due to branch retinal vein occlusion (BRVO).METHODS: A consecutive series of patients with ME due to BRVO who were treated with intravitreal bevacizumab injection (2.5g/0.1L) were retrospectively studied. Patients underwent complete ophthalmoscopic examination, including Snellen visual acuity testing, optical coherence tomography (OCT) imaging, and/or flurescence angiographic testing at baseline and follow-up visits.RESULTS: There were 32 eyes of 32 consecutive patients who received at least one intravitreal bevacizumab injections (range from 1 to 3). The mean length of follow-up was 4.7 (range from 3 to 8) months. The mean visual acuity improved from 20/200- at baseline to 20/100- at 1 month and 20/100+ at 3 months and last follow-up (P＜0.01). The mean central 1mm macular thickness was 483μm at baseline and decreased to 275, 314,and 301μm at 1 month,3 months, and last follow-up (P＜0.01)respectively.No adverse side effects were observed following injections in any eyes.CONCLUSION: Intravitreal bevacizumab (Avastin) showed a marked decrease in ME secondary to BRVO, improvement in visual acuity and lack of adverse side effects.

ObjectiveTo observe effect of head and body acupuncture and moxibustion on stroke.Methods183 stroke patients were randomly divided into 3 groups, head acupuncture and moxibustion, body acupuncture and moxibustion, and head body acupuncture and moxibustion. After two months treatment, effects of 3 groups were evaluated.ResultsThere were no differences between head group and body group, body group and head body group, but there was significantly difference between head body group and head group (P<0.05).ConclusionThe head body acupuncture and moxibustion can gain the best clinical effect on stroke patients compared with simply head or body acupuncture and moxibustion.

Objective To investigate the application of two-factor theory of nursing students to improve the quality of teaching.Methods for nursing students of 2009,through the application of two-factor theory,to take effective measures to meet the health factors,and use incentives to improve nursing students to learn initiative and enthusiasm,for the nursing students of 2008,using the traditional clinical teaching methods.Results The 2008 nursing students theory test scores for (83.94 ±8.21 )points,operation test scores for (81.28 ±6.54)points,zongping scores for (82.47 ± 6.89 )points; The 2009 nursing students theory test scores for (87.17 ± 5.13 )points,operation test scores for (85.24 ± 4.61 )points,zongping scores for (86.27 ± 7.14)points,two groups of comparisons were statistically significant differences(t =-3.72,-4.14,-3.97;P ＜0.05).Conclusions Thetwo-factor theory can improve nursing students to learn initiative and enthusiasms to improve the quality of teaching.

Background and purpose:Three-dimensional power Doppler angiography (3D-PDA) is a new technique to investigate the vessels in the organs, but the research in thyroid is limited. The purpose of this research was to investigate three-dimensional power Doppler angiography (3D-PDA) in differentiating malignant from benign thyroid nod-ules.Methods:This study prospectively evaluated 103 lesions in 94 patients who were scheduled for surgery. The patients underwent preoperative 3D-PDA scanning. Analysis of the 3D-PDA characteristics includes blood flow pattern, the num-ber of blood vessels, the shape of vessels, the spatial distribution of the vessels, the existence of rich local blood flow within nodules or in the parenchyma surrounding the nodules. This study also analyzed the difference between the benign lesions and the malignant lesions.Results:There were 50 benign lesions and 53 malignant lesions. The sensitivity and specificity of irregular vessels, the asymmetry spatial distribution, rich local blood flow within nodules or in the parenchyma surround-ing the nodules were 64.2%, 96.0%; 56.0%, 88.0%; 54.7%, 96.0%; 60.4% and 94.0%, respectively. The sensitivity, speci-ficity, positive predictive value, negative predictive value and accuracy of 3D-PDA were 83.0%, 94.0%, 93.6%, 83.9% and 90.3%, respectively.Conclusion:3D-PDA provides a useful tool to investigate vascularization of thyroid leisions.This technique is feasible for clinical application and plays an important role in diagnosis of thyroid nodules.

Xuzhou Cancer Hospital explored a development and reform of the hospital in the PPP framework,while adhering to the principles of Public nature as before,staff status as before,and government supervision as before. The reform features proactive attempts in operation and management,personnel management,and remuneration system,in an effort to build an operation system featuring board governance,total cost accounting,and dynamic total salary management in its reform toward building an innovative mixed ownership.
