Positron emission tomography-computed tomography (PET-CT) is widely used in the diagnosis and grading of FDG-uptake lymphoma,particularly in the extranodal lesions.Baseline PET-CT improves the accuracy of subsequent response assessment.Focal FDG uptake within the bone or bone marrow is highly sensitive for involvement in Hodgkin' s lymphoma (HL) and diffuse large B-cell lymphoma (DLBCL) and is better than bone marrow biopsy.Many international trials suggest that interim scan is prognostic,but not proven as a method to guide therapy.A negative PET-CT scan at the end of therapy is the best predictor of a good outcome.However,surveillance PET-CT scan should not be done routinely.

This paper reports serum ?_2 microglobiln (?_2M in abbreviation) in 216 normal children of different ages. Urin ?_2M in 60 normal adults; and both in 50 cases of common glomerular disease in children were detected by RIA. The results showed that serum ?_2M is more accurate than BUN in judging the renal function. The elecating serum ?_2M is coincidence with the elevating of diastolic pressure of the sick children. The dynamic observation on delayed cases examination of serum ?_2M and urin ?_2M may be of help in monitoring the pathological changes in glomerular and tubule.

Objective:To observe the relationship between the vascular endothelial growth factor (VEGF) and the survival of flap in the rat back which received radiotherapy. Methods: Forty Wistar rats were divided into four groups. A 3×4 cm~2 full thickness dorsal flap with pedicle was prepared at the posterior end. The skin flaps were given~(60)Co radiotherapy in the 2, 4, 6 day postoperation. Group A was given of VEGF in the third, fifth, seventh day. Group B was given a high quantity of VEGF. Group C was the control of Group A,Group D was the control of Group B. Control groups received normal saline. Results: Pathological observation revealed that the survival of flap and blood vessel lumen diameter of group A were higher than that of group B(P<0.05). Group A showed remarkable difference compared with group C(P<0.01). Group B showed remarkable difference compared with group D(P<0.05). Results of fluorescence staining and SDH examination showed that three times injection had better results than one time injection. Conclusion: Three times injection of VEGF has better effect on the viability of rat skin flap than one time injection.

Objective To study whether the positive psychological capital intervention could improve the level of psychological capital and the will of retention of clinical nurses. Methods A randomized controlled trials was conducted. The control group did not take any psychological intervention;Intervention group was given psychological capital intervention, which was conducted for 7 weeks (once a week, 1-2 hours per time).It used Nurses′ Psychological Capital Questionnaire and Nurses′ Retention Intention Questionnaire to evaluate the participants before and after intervention. Results There were no statistical differences between intervention group and control group in the score of Nurses′Psychological Capital Questionnaire (84.74 ± 10.04 vs. 86.16 ± 8.57,P > 0.05 ) and Nurses′ Retention Intention Questionnaire ( 19.21±3.47 vs. 18.54±3.41,P>0.05 ) on the day before intervention. The score of Nurses′Psychological Capital Questionnaire of intervention group was 93.89 ± 7.10 on the intervention day and 93.60 ± 6.88 three months later while the control group scored 84.41 ± 6.58 and 83.92 ± 9.31.The intervention group was statistically lower than the control group (t=6.156, 5.155, P<0.05) .And the score of Nurses Retention Intention Questionnaire was 22.42±2.66 on the intervention day and 22.24±2.61 three months later while the control group scored 18.61 ± 3.08 and 19.21 ± 3.47. The intervention group was statistically lower than the control group (t=5.866, 4.292, P<0.05). Conclusions Positive psychological capital intervention can improve the the will of retention of clinical nurses.

In this study, polyelectrolyte microcapsules have been fabricated by biocompatible ferrosoferric oxide nanoparticles (Fe3O4 NPs) and poly allyamine hydrochloride (PAH) using layer by layer assembly technique. The Fe3O4 NPs were prepared by chemical co-precipitation, and characterized by transmission electron microscopy (TEM) and infrared spectrum (IR). Quartz cell also was used as a substrate for building multilayer films to evaluate the capability of forming planar film. The result showed that Fe3O4 NPs were selectively deposited on the surface of quartz cell. Microcapsules containing Fe3O4 NPs were fabricated by Fe3O4 NPs and PAH alternately self-assembly on calcium carbonate microparticles firstly, then 0.2 molL(-1) EDTA was used to remove the calcium carbonate. Scanning electron microscopy (SEM), Zetasizer and vibrating sample magnetometer (VSM) were used to characterize the microcapsule's morphology, size and magnetic properties. The result revealed that Fe3O4 NPs and PAH were successfully deposited on the surface of CaCO3 microparticles, the microcapsule manifested superparamagnetism, size and saturation magnetization were 4.9 +/- 1.2 microm and 8.94 emu x g(-1), respectively. As a model drug, Rhodamin B isothiocyanate labeled bovine serum albumin (RBITC-BSA) was encapsulated in microcapsule depended on pH sensitive of the microcapsule film. When pH 5.0, drug add in was 2 mg, the encapsulation efficiency was (86.08 +/- 3.36) % and the drug loading was 8.01 +/- 0.30 mg x m(L-1).

Objective To study the effects of erythropoietin(EPO) and angiotensin receptor blocker on the expression of eNOS and Bcl-2 after cerebral ischemia.Methods The model of focal cerebral ischemia was made by occluding middle cerebral artery(MCA) for 2h and reperfusing for 48h in healthy Sprague-Dawley rats.The rats received EPO 3 000u · kg-1 · d-1 or valsartan 40mg · kg-1 · d-1 by intraperitoneal injection just before the beginning of reperfusion and after reperfusion.The expression of eNOS and Bcl-2 was detected.Results Compared with ischemia group,Bcl-2 and eNOS expressions in EPO-treated group and EPO-ARB treated group were significantly increased (P ＜ 0.05).eNOS expression in ARB-treated group was significantly increased (P ＜ 0.05),Bcl-2 expression was up-regulated,but it had no significant difference.Conclusion EPO had protective effects on cerebral ischemia-reperfu-sion injury in rats,which partially mediated by up-regulating of Bcl-2 and eNOS expression.Angiotensin receptor blocker had protective effects on cerebral ischemia-reperfusion injury in rats,which partially mediated by up-regulating of eNOS expression.

Aim To test the strength of Kraekow bilateral locking stitchfor tendon or ligament free end fixation and evaluate the stitch which wasused in reconstruction of cruciate ligament or secure fixation of soft tissue tobone. Methods Twenty-four specimens of patellar tendon free end, whichwere divided into 3 groups according 2 or 3 stitches and 6 subgroups ac-cording No1 Ethilon or 0.4 mm diameter stainless steel wire different suturematerials, fixed with Krackow locking stitch, were undertaken the tensiletest respectively, so as to find out the least stitches and efficient suture pat-tern. Results 2 Krackow locking stitches had more strength than that of0.4 mm diameter stainless steel wire, the fixation strength of 2 stitcheswhich used No1 Ethilon was more than 80 N, superior to the failure strengthof material itself, it still maintained the same strength if the first stitch wasacross the tendon tissuetransversely. There was no significant differencebetween 2 and 3 Krackow locking stitches in suture strength statistically, thefixation strength was superior to the suture material, it could reduce the'suture exposure when the first stitch is across the tendon tissue while main-tains a comparable strength to other suture. Conclusion If attempt to makea higher strength of suture, we should focus on selecting a stronger materialsor adding the suture materials in number rather than the stitch number.
