The rise of advanced nursing practice in the developed countries promotes the development of nursing science, nursing postgraduate education arises at the historic moment. Professional nursing postgraduate education started late in our country and its development is not mature, there exists some problems in the training plan and professional positioning, such as training process not realizing the training objectives, unreasonable curriculum setting and evaluation system, unclear professional direction, disconnection of vocational orientation and the professional qualification and specialist nurse certification. Therefore, nursing professional degree graduate education mode needs further exploration and unity.

Objective To investigate the effects of low dose radiation on the level of oxidative damage and antioxidant in population of high background radiation area of Guangdong.Methods A total of 48 male residents who lived in high background radiation area(HBRA) of Guangdong province and 48 male residents who lived in neighboring Enping control area were chosen as the objectives and control respectively.The peripheral venous blood of two groups was collected,and then the levels of 8-OHdG and TrxR were determined by enzyme linked immunosorbent assay (ELISA).Results Compared with the CA group [(315.39 ± 100.59) ng/ml],the level of 8-OHdG [(272.64 ± 96.85) ng/ml] decreased significantly in HBRA (t =2.121,P ＜0.05).Compared with the CA group [(0.467 ±0.056) ng/ml],the level of TrxR [(0.496 ± 0.044) ng/ml] increased significantly in HBRA (t =-2.823,P ＜ 0.05).The results of multiple linear regression analysis demonstrated that the chronic exposure to low dose of radiation had significant effects on the expression level of 8-OHdG and TrxR (t =-2.327,2.367,P ＜ 0.05) after adjustment for confounding factors such as age,drinking,tea drinking,smoking,medical exposure and stressful events.Conclusions Chronic exposure to low dose radiation may decrease the level of oxidative and enhance the level of antioxidant.

Objective To explore the current research status and existing problems in severe burn nursing by reviewing relevant literature of severe burn nursing published in 6 kinds of nursing core journals. Methods Search 6 kinds of nursing core journals using the following key words: severe burn critical burn serious burn large area burn intensive burn and nursing. Applying bibliometrics to conduct descriptive analysis of the external and internal characteristics of these papers. Results Two hundred and nine papers were included;the main literature research type of thess articles was clinical experience summary, the content of these literature was extensive. Conclusions Severe burn nursing research focus on clinical symptomatic nursing; clinical nurse scientific research ability needs to be strengthened, and subject aspects should be paid more attention to children, the elderly, and clinical nurse physical and psychological conditions.

Objective To investigate the in vitro susceptibility of Minocycline and polymycin B against clinical islates of pan-drug resistant Acinetobacter baumanii ,to provide laboratory support for clinical treatment for drug selection.Methods The susceptible test of Minocycline and polymycin against 39 isolates of pan-drug resistant Acinetobacter baumanii were determined by K-B meth-od.Results 38 strains of pan-resistant Acinetobacter baumanii were sensitive to polymyxin B,sensitive rate was 97.4%,20 strains sensitive to minocycline,the sensitivity rate was 51.3%.polymyxin B sensitivity was more sensitive than Minocycline (P < 0.05). Conclusion Polymycin B had strong activit ies against pan-drug resistant Acinetobacter baumanii .

ObjectiveTo investigate the action mechanism of CD20 lymphocyte infiltration in the renal allograft biopsy with chronic allograft nephropathy (CAN).MethodsCAN cases confirmed by renal biopsy within 2 years after renal transplantation served as study subjects. By using immunohistochemistry,the deposition of C4d and the CD20-positive lymphocytes infiltration in the renal grafts were examined.The clinical follow-up data were analyzed.ResultsForty-four cases of CAN were enrolled in the study, including 13 cases (29.5％ ) of CD20-positive lymphocytes infiltration,and 31cases (70.5％ )of CD20-negative lymphocytes infiltration. CD20-positive lymphocytes in biopsy showed nodular and scattered lymphocytes infiltration.There were 5 (26.3％)cases of CAN Ⅰ,4 cases (25.0％) of CAN Ⅱ,and 4 (44.4％) of CAN Ⅲ in CD20-positive group.There was no statistically significant difference between the only CAN group and CAN with AR group in CD20-positive rate.Immunohistochemical staining showed there were 12 cases (27.3％) with C4d linear deposition in peritubular capillary endothelial cells (PTC).C4d positive rate had no significant difference among the CAN classifications. There was no significant relationship between C4d deposition and CD20-positive lymphocytic infiltration.The average serum creatinine in CD20-negtive group and CD20-posigtive group was 140.8 ± 22.0 and 183.5 ± 25.5μmol/L before biopsy,and 165.6 ± 37.6 and 242.2 ± 59.1 μmol/L one year after biopsy.The average serum creatinine level in CD20-positive group was higher than in CD20-negtive group before and after biopsy.ConclusionProgressive chronic humoral immunity is high risk in the process of CAN. The CD20-positive lymphocyte infiltration has no relevance with CAN grade and C4d deposition in PTC,but is associated with circulating antibody PRA and allograft long-term outcome. Pathogenetic mechanism may not contribute to chronic humoral immune,but B cells presenting donor antigens,are recognized and activated by T cells as antigen-presenting cells.

OBJECTIVETo compare the clinical effects of different surgical methods for the epicanthus corrective surgery.

METHODSCanthoplasty with asymmetric Z-flap is applied in 46 cases, Y-V advancement procedure for epicanthoplasty is applied in 42 cases. The epicanthus aesthetic measurement were measured and calculated by software before and after surgery, the diameter of the iris was measured as a reference value,and the postoperative scar was assessed by VSS scale. At the same time, by measuring the lateral canthal distance, the accuracy of the measurement method can be verified.

RESULTSAll patients were satisfied with the long-term results and there were no recurrences of the epicanthal fold. The shortening ratio of the ICD is 8.36% in the group with the Z-plasty, and 5.88% in Y-V plasty. the lateral canthal distance have no diffrence before and after surgery.

CONCLUSIONSTwo surgical methods can get good results. The magnitude of correction in Z-plasty may larger than Y-V plasty, but postoperative retraction may existed in Z plasty.

Objective To discuss CT and MRI manifestations and the differential diagnosis of hepatic tuberculosis.Methods The imaging manifestations of hepatic tuberculosis proved by pathology in 2 cases were analyzed retrospectively with literatures review.The plain and contrast-enhanced CT scans were performed in 2 cases and 1 case underwent plain MRI.Results On plain CT scan,the lesion was non-homogeneous low density with even more low density in the center in 1 case,and nearly isodensity in another case.On contrast-enhanced CT scan,the lesions were no enhancement in arterial phases,and slight enhancement in venous phase and balance phase.In 1 case,slight enhancement was also shown surrounding the necrotic area.On MR plain scan,the lesion demonstrated low signal intensity on T_1WI,iso-and high mixed signal intensity on T_2WI.Conclusion Hepatic tuberculosis is rare seen,so it is easy to misdiagnosis.CT and MRI scanning can demonstrate some features of hepatic tuberculosis,especially dynamic enhanced scanning is very helpful in diagnosis and differential diagnosis.
