Objective To analyze satisfaction of the clinical practice content of nursing postgraduates with different characteristic, and to provide transformative suggestions for the construction of clinical practice scheme of nursing postgraduates. Methods Using judgment sampling and snowball sampling, the questionnaire survey was conducted among 101 nursing postgraduates, and comparing satisfaction of clinical practice content of postgraduates with different age, work experience and teaching mode. SPSS 17.0 software package was used for data description and t test. Results The total satisfaction of clinical practice content of nursing postgraduates was low, and different postgraduates′satisfaction was different. On practical operation opportunity,> 30 years old of postgraduates′satisfaction was (3.95±0.87), which was higher than those 20~30 years old, (3.35±0.90), and the difference was statistically significant, t=2.748, P<0.01. On clinical practice assessment methods and frequency, the satisfaction of postgraduates with a fixed teacher was higher than those without a fixed teacher (3.40±0.74) vs. (2.83±0.87), and the difference was statistically significant, t=3.310, P<0.01. Conclusions At present, the clinical practice content of nursing postgraduates is in shortage, and need to be further improved.

OBJECTIVE: To analyze the features of orbital fracture and to discuss its forensic expertise points. METHODS: One hundred and thirty cases of simple orbital fracture from 2010 to 2012 collected from one public security bureau were retrospectively analyzed such as age, gender, tools, position and morphology of the fracture, periorbital and orbital compound injury and the follow-up results after 6 months. RESULTS: In the 130 cases, the wounded were mainly young men and hit by fist. The fracture of simple medial orbital wall accounted for up to 81.5% in all cases. In the periorbital and orbital compound injury, laceration and contusion of eyelid and ethmoidal cellules and maxillary sinus always occurred. After 6 months follow-up, there were 30 cases of comminuted fracture remained enophthalmos compared with the uninjured side. CONCLUSION It is inappropriate to judge the fracture of simple medial orbital wall as minor injury. We should judge the degree of simple orbital fracture after the injury is stable. Detailed ophthalmology inspection is necessary for forensic expertise of simple orbital fracture.

Objectives To compare the effect of one-stage revision and two-stage revision for the treatment of culture-negative peripros-thetic joint infection after total hip arthroplasty.Methods A retrospective study was conducted with the clinical data of 41 patients who had chronic periprosthetic joint infection after total hip arthroplasty and then underwent one or two-stage revision surgery from February 2006 to February 2014.The patients were divided into two groups according to different surgical way,namely the 16 patients who received the one-stage revision surgery were regarded as the OSR group,and the other 25 cases who underwent the two-stage revision surgery were regarded as the TSR group.The clinical efficacy of the two surgical way were assessed with Harris Hip score,visual analogue scale (VAS),and rate of infection clearance.Results The average duration of follow up was 29.7 months (9 to 48 months).At the last follow-up,Harris Hip score of TSR group was higher than that of the OSR group,and the difference was statistically significant (P =0.04),and the VAS score of TSR group was lower than that of the OSR group with statistical differences (P =0.02).Additionally,the rate of infection clearance in TSR group was significantly higher than OSR group (P =0.04).Conclusion Culture-negative periprosthetic joint infection can be effectively controled by one or two-stage revision surgery.However,patients got a better prognosis after two-stage revision surgery.

BACKGROUND:Retinoid X receptor (RXR) plays a central role in the regulation of intracellular receptor signaling pathways. The activation of RXR has protective effect on H2O2-induced apoptosis of H9c2 ventricular cells in rats. But the protective effect and mechanism of activating RXR in cardiomyocytes against hypoxia/reoxygenation (H/R)-induced oxidative iniury are stillunclear. METHODS:The model of H/R injury was established through hypoxia for 2 hours and reoxygenation for 4 hours in H9c2 cardiomyocytes of rats. 9-cis-retinoic acid (9-cis RA) was obtained as an RXR agonist, and HX531 as an RXR antagonist. Cultured cardiomyocytes were randomly divided into four groups:sham group, H/R group, H/R+9-cis RA -pretreated group (100 nmol/L 9-cis RA), and H/R+9-cis RA+HX531-pretreated group (2.5 μmol/L HX531). The cellviability was measured by MTT, apoptosis rate of cardiomyocytes by flow cytometry analysis, and mitochondrial membrane potential (ΔΨm) by JC-1 fluorescent probe, and protein expressions of Bcl-2, Bax and cleaved caspase-9 with Western blotting. Allmeasurement data were expressed as mean±standard deviation, and analyzed using one-way ANOVA and the Dunnett test. Differences were considered significant whenP was <0.05. RESULTS:Pretreatment with RXR agonist enhanced cellviability, reduced apoptosis ratio, and stabled ΔΨm. Dot blotting experiments showed that under H/R stress conditions, Bcl-2 protein level decreased, while Bax and cleaved caspase-9 were increased. 9-cis RA administration before H/R stress prevented these effects, but the protective effects of activating RXR on cardiomyocytes against H/R induced oxidative injury were abolished when pretreated with RXR pan-antagonist HX531. CONCLUSION:The activation of RXR has protective effects against H/R injury in H9c2 cardiomyocytes of rats through attenuating signaling pathway of mitochondria apoptosis.

Objective To study the state of doctors' psychological capital in public hospitals,and to analyze the characteristics of such capital,so as to better leverage the capital as a hospital management tool.Methods A quantitative and qualitative research was made on the state of doctors＇ psychological capital.Results The doctors' task-oriented psychological capital scored 4.25,and guanxi-oriented psychological capital 4.41; “modesty and prudence”scored the highest in all dimensions of the doctors' psychological capital,“optimism and hope”lowest; the doctors with different genders,ages,seniority,and monthly average income have a difference in psychological capital.However,no significant difference was found with varying titles,hospital levels,and employment models.Conclusion The doctors were found with a strong psychological capital to cope with stress.Better psychological capital will raise quality of care in practice.

Objective To evaluate the clinical efficacy of percutaneous transhepatic biliary drainage (PTBD) and pcrcutaneous transhcpatic insertion of biliary stent (PTIBS) for malignant biliary obstruction.Methods PTBD or PTIBS were performed in 56 patients with malignant biliary obstruction, which were aused by hepatic carcinoma (n = 14), biliary duct carcinoma (n = 11), gallbladder carcinoma (n = 5),stomach carcinoma accompanied with metastasis of lymph node (n = 14), carcinoma of ampulla (n = 1 ) or carcinoma of pancreatic head (n = 11 ). The diagnosis was confirmed by ultrasonography, CT or MRI in all patients. The obstructed site was well identified, including high obstruction in 19 patients and lower obstruction in 37 patients. Based on the imaging findings, suitable interventional procedure was employed.Results PTBD or PTIBS were performed successfully in all 56 patients, of them PTBD was adopted in 11,PTIBS in 40 and both PTBD and PTIBS in 5. The serum total bilirubin decreased from (295.65±152.86)μmol/L before the procedure to (151.05 ± 107.36) μmol/L after the procedure, (P < 0.01 ). Postoperative infection could affect the fading of jaundice (P < 0.01 ), but the location of the obstruction carried no relationship with the fading of jaundice (P = 0.063). Conclusion Both PTBD and PTIBS are safe and effective palliative therapies for malignant biliary obstruction, which can markedly relieve patient of jaundice,improve the quality of life and elongate the survival period.

Objective To analyze the MR imaging features of pyocephalus. Methods MR imaging features!of pyocephalus in 5 cases with clinically proved were analyzed retrospectively. All patients were undergone no-contrast MR imaging. 3 patients received diffusion weighted-imaging(DWI). Results In all five patients,the debris and pus with pus-fluid level were shown inside the lateral ventricle.The debris or pus was slightly hyperintense on T1WI, slightly hypointense on T2WI relative to cerebrospinal fulid(CSF). On DWI, the debris was hyperintense in 1 case and isointense in 2 cases.Conclusion The features of MR imaging of pyocephalus is specific. MR imaging is valuable in the diagnosis of pyocephalus.

Objective Exploration of TSH, FT3, FT4 changes in critical condition prior to death.Methods 84 patients that were anti-tumor therapy acceptable and not associated with the treatment of thyroid disease in patients with terminal tumors. Age from 24 to 85-year-old, male 56, female 28. The use of SELDI technology (surface-enhanced laser description / ionization time-of-flight mass spectrometry protein chip technology) checks to M/Z for the 11 100 + H～11 900 + H peak of the cluster, divided into the positive group for critically ill patients with early warning protein (LGT) and the negative group for it. All patients were given TSH, FT3, FT4 inspection. The results were statistically analyzed. Results TSH, FT3, FT4 in the LGT positive group was significantly lower than in the negative LGT group. There was no correlation between TSH,FT3 and FT4 in the LGT positive group;In the negative LGT group FT3 and FT4 had a positive correlation,and FT3 and TSH no relevance. Conclusion Thyroid function is normal in the stage of cancer patients stable condition. Possible pituitary-hypothyroidism may occur as the disease advances to the end or before death.This may be an important factor causing the acceleration to the death of the patients. However, the cause and effect between this phenomenon and the early warning of protein fingerprint group(LGT) is still not clear. In critical condition checking thyroid function and render supplementary amount of thyroid hormone in accordance with the checking results may be beneficial.
