Objective To explore the application of “PBL -Seminar” teaching method in nursing teaching for undergraduates majoring in nursing.Methods 54 nursing undergraduates from July 2012 to April 2013 were set as control group receiving the traditional teaching method, and another 52 nursing undergraduates from July 2013 to April 2014 at internship were set as experimental group, receiving “PBL -Seminar” teaching method, and then the two groups were compared in terms of teaching effects.Results The patient satisfaction was obviously improved, and the qualification rate of the nursing students and the comprehensive evaluation score were significantly higher as com-pared with the control group (p <0.5).Conclusion “PBL -Seminar” teaching method can effectively improve the effect of the nursing internship of nursing undergraduates and the teaching quality for the nursing undergraduates.

OBJECTIVE: To analyze the occupational hazardous factors in hospital pharmacy so as to enhance pharmacist’s awareness of self-protection against such hazards. METHODS: The occupational hazardous factors including physical factors, chemical factors and psychological factors etc were analyzed and the countermeasures were discussed. RESULTS & CONCLUSIONS: Pharmacists should be cautious to the occupational hazards, strengthen traning and education, raise awareness of self-protection to guard against the occupational hazard event.

Third-generation aromatase inhibitors (AIs) have been considered as standard adjuvant endocrine therapy for hor-mone-responsive breast cancer in postmenopausal women. Aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) are prevalent among patients undergoing AI therapy;these symptoms result in reduced quality of life and poor dependence to AI treatment. The mechanisms mediating AIMSS and the effective management of AIMSS have not been extensively investigated. This article re-views the incidence, clinical characteristics, possible mechanisms, and treatment of AIMSS.

Objective To characterize the effects of AQP1 expression on kidney damage in rat disseminated intravascular coagulation(DIC) caused by lipopolysaccharide(LPS) dosing. Method Fifty male Wistar rats (clean grade) were randomly assigned into 5 groups of 10 rats. The 10 control rats were dosed with 10 ml of 0.9%NaCl solution by a drip via the vena caudalis within 4 h, and blood and tissues were obtained after treatment completion. In the DIC groups, the rats were dosed with LPS (30 mg/kg body weight in 10 ml of 0.9% NaCl solution) by a drip via the vena caudalis within 4 h, and blood and tissues were obtained at 4, 6, 8 and 10 h. The blood platelet(PLT) count, prothrombin time(PT) , activated partial thromboplastin time(APTT), fibrin(FIB) and D-dimer(D-D) were detected. Hematoxylin and eosin(HE) staining was used to examine the pathologic changes in the lung and kidney tissues of each group (both hematologic parameters and tissue pathologic changes were used to judge the course of DIC). The AQP1 gene expression levels in the kidney tissues from the groups were evaluated by the mRNA levels using RT-PCR. Statistical analyses were performed by the SNK- q method. Results The PLT count, PT, APTT, FIB and D-D examinations revealed remarkable changes in all DIC groups compared with the control group (P < 0.01). The AQP1 mRNA level was significantly decreased in the DIC group at 4 h compared with the control group (P < 0.01) , and further decreased to the minimum level in the DIC group at 6 h. Moreover, cloudy swelling of renal tubular cells was observed at 6 h and cell degeneration and necrosis were observed at 8 h among the DIC groups. Conclusions Downregulation of AQP1 mRNA expression occurred before damage to the renal tubular cells in DIC, indicating that AQP1 expression may be involved in the kidney damage observed in rat DIC.

Objective To investigate the CT imaging findings of thymus and thyroid gland involved in Langerhans cell histiocytosis(LCH) of pediatric patients. Methods CT image findings in pediatric patients with LCH confirmed by pathology and clinical diagnosis from January 2006 to February 2015 were retrospectively analyzed. By radiography, 38 cases' thymus gland were involved and 8 cases' thyroids gland were involved. Results Plain CT scan for thymus gland involved patients revealed 9 cases were shown as hyperplasia, 17 cases were shown as calcification, 9 cases were shown as hyperplasia with calcification, 1 case was shown as cavity, 1 case was shown as hyperplasia with calcification and cavity and 1 case was shown as hyperplasia with calcification and low density. Enhanced CT scan for thyroid gland involved patients showed bilateral or unilateral enlargement of thyroid gland with heterogeneous low density and unobvious enhancement. Conclusions Finely calcifications were the most common CT findings on thymus gland involved in LCH and might without hyperplasia. CT imaging of thyroid LCH exhibited an enlarged or normal size and abnormal density in the thyroid gland with adjacent soft tissues involved.

Objective To explore the imaging features on chest radiograph and CT in children with Influenza A H1N1 pneumonia. Methods The imaging data of chest radiograph and CT in six children with Influenza A H1N1 pneumonia confirmed by real-time RT-PCR assay was retrospectively analysis. All patients had chest radiograph at first examination and 4 of them re-examed. One children took CT. Results All cases showed thick lung markings with varied degrees of pulmonary infiltration and interstitial changes on chest radiograph. Among them, 3 cases showed bilateral pulmonary infiltration and 3 cases showed infiltration in left lung; enlarged hilar was observed in 3 cases. The imaging findings of the pneumonia changed quickly during the follow-up accompanied with the improvement of clinical symptoms. The only one chest CT examination showed bilateral infiltration, multiple ground-glass opacities,small subpleural nodulars, right pleural effusion and lymphadenopathy of lung hila and mediastinum. Conclusions Chest radiograph and CT revealed certain typical imaging features in the children with influenza A H1N1 pneumonia. However, the final diagnosis of influenza A H1N1 pneumonia still should be made based on epidemiology and laboratory examination.

Objective To find an ideal method of DNA isolation from blood and especially from clotted blood and to minimize the volume of blood collected for laboratory and clinical tests.Methods DNAs were isolated from antiagglutinated and agglutinated blood samples from auricular veins of 30 healthy subjects. The DNAs of these samples were obtained by a nonenzymatic, nontoxic procedure optimized by us and determinated by agarose gel electrophoesis and PCR. Results The yields of DNA isolated from clotted blood and antiagglutinated blood were (40.2?8.86)mg DNA/L and (39.1?10.2)mg DNA/L, and purities were 1.87?0.11 and 1.92? 0.12. The DNAs that we isolated from all samples had high molecular weight and by PCR the dimorphism of ALU alleles of the 8th intron of t-PA was easy to be obtained, so they were complete and reliable. Conclusion This method is rapid, easy, efficient and nontoxic for isolation of DNA from clotted and fresh blood and meets requirements for clinical testing and molecular biology study.

Animal models of pulmonary artery hypertension (PAH),aiming to simulate human characteristics of the disease,have contributed extensively to understanding the pathophysiology of PAH and the investigation of experimental treatments.The classical models include monocrotaline models,chronic hypoxia model and so on,more new models were investigated in recent years.These animal models were not able to perfectly mimic human pathological characteristics of PAH because of the defect in different aspects.In this review,both typical and novel methods of PAH modeling were summarized and evaluated to provide a suitable guidance for the settlement of animal models which can meet human characteristics comprehensively.

Objective To investigate the incidence and risk factors of acute kidney injury (AKI). Methods The clinical data of 438 patients with severe pneumonia who were admitted in the intensive care unit in 2016 were retrospectively analyzed for analysis of AKI and assessment of risk factors. Results Among the 438 patients with severe pneumonia,the incidence of AKI was 53.42%. Within 72 hours after admission into the ICU, 86.75% of them developed AKI mainly from hypovolemic or septic shock(accounting for 80.34%). The detection rate of AKI by the standards of RIFLE and AKIN was lower than by the standards of KDIGO (45.89%,48.17%vs. 53.42%). Anemia ,shock /hypotension ,drugs ,RRT ,APPACHE II scores were the predictors of AKI. Conclusions The incidence of severe pneumonia complicated with AKI is high. Most of the patients develop it in 72 hours after admission into the ICU. Anemia,shock/hypotension,drugs,RRT,APPACHE II scores are its risk factors.
