Objective To build new management model for diabetic foot disease,and to observe the therapeutic effect of diabetic foot ulcers under the new model.Methods 52 patients with newly diagnosed diabetic foot disease were recruited and randomly divided into the experimental group (n=26) and the control group (n=26).While the experimental group adopted the interdisciplinary collaboration model (nurse-doctor jointed diabetes care management model),the control group were treated by the single department pattern.The foot ulcer healing rate,average length of stay (ALOS),fasting plasma glucose (FPG),2 h postprandial blood glucose (2 h PBG),glycosylated hemoglobin (HbA1c),and the patient awareness of the knowledge about diabetes self-management were respectively compared at 3 and 6 months.Results After receiving a multidisciplinary joint diagnosis and treatment,FPG and 2 h PBG of the patients from the experimental group [(6.44±2.93)mmol/L,(8.52± 2.09)mmol/L] were significantly decreased than those of the patients from the control group [(8.17±3.19)mmol/L,(10.77±3.27)mmol/L].HbA1c at 3 and 6 months (7.2％,7.7％) and ulcer recurrence rate (3.8％) after 6 months of patients of the experimental group were significantly reduced than those of the control group(8.9％,9.1％ and 15.4％).When compared with patients of the control group,patients of varying severity in the experimental group showed significantly shortened ulcer healing time and hospital stay.Moreover,patients from the experimental group showed statistically higher knowledge level and self management ability (P＜0.05).Conclusion Through interdisciplinary collaboration,podiatric medical joint management model can significantly improve cure rate,shorten ALOS,improve blood sugar control and patient satisfaction.

Objective The purpose of this study was to investigate the clinical significance of pre-operative combined detection of metastasis-relative genes in non-small cell lung cancer. Methods Peripheral blood lymphocyte specimens from 46 patients before operation and fresh tissue specimens after operation were examined by RT-PCR analysis of CD44v6 and nm23H1 mRNA. The results were compared to the pathological diagnosis of lymph node metastases. ROC curve was used to determine the cut-off value of pre-operative metastases prediction. Results The relative amount of CD44v6 mRNA was higher (P

Objective To investigate the clinical characteristics, diagnosis, treatment and prognosis of malignant fibrous histiocytoma (MFH) of thyroid. Methods The clinical case and follow-up data (n=3) of MFH of thyroid from our hospital between 2000 and 2007 was analyzed, with the correlating references reviewed. Results MFH of thyroid accounted for 0.574% (3/523) of malignant tumor of thyroid. MFH of thyroid progressed so fast as to invase recurrent laryngeal nerve (RLN) and /or cervical lymph nodes. Conclusions The diagnosis of MFH of thyroid is difficult, for it is easy to be misdiagnosed as thyroid carcinoma. Immunohistochemistry pathology can provide a good differential diagnostic value, with CK negative, Tg negative, and Vimentin positive to support the diagnosis of MFH. Extensive and thorough excision should be the main choice to treat MFH of thyroid. Patients of MFH of thyroid often died of recurrence or metastasis in 2 years after operation. MFH of thyroid is a kind of rare thyroid primary tumor, with malignancy of high grade and poor prognosis. The disgnosis of MFH of thyroid depends on immunohistochemistry staining, while excision should be the main choice for treatment.

Objective To assess whether the plaque volume of carotid artery evaluated by three-dimensional ultrasound can predict the risk of cardiovascular events earlier in patients with coronary heart disease, in comparison with plaque thickness.Methods A total of 99 patients were enrolled, including 66 patients with asymptomatic carotid plaque and 33 patients with coronary heart disease (CHD) and carotid plaque.Three-dimensional ultrasound was performed in all the patients.Coronary angiography was performed in all the patients in CHD group.Coronary artery Gensini score was calculated.Plaque thickness, plaque area and plaque volume were compared between the two groups.We analyzed the relationship of plaque volume with Gensini score and other cardiovascular risk factors.Results Plaque volume was significantly higher in CHD group [(1312.38±513.70)mm3] than in asymptomatic group [(947.54±321.41)mm3] (P=0.023).However, plaque thickness and plaque area were not significantly different between the two groups (P>0.05).Plaque volume was positively correlated with Gensini score (r=0.519, P=0.002), homocysteine (r=0.569, P=0.002), and cardiovascular risk factors such as diabetes, blood glucose and glycosylated hemoglobin.There was a negative correlation between plaque volume and high-density lipoprotein (HDL), a factor protecting against cardiovascular events (r=-0.387, P=0.038).Conclusion Compared with plaque thickness, the volume of carotid plaques assessed by three-dimensional imaging technique may be a better predictor of the risk of cardiovascular events in patients with coronary heart disease.

Objective To learn the status quo of core competency of registered nurses in tertiary level first-class hospitals in Liaoning Province and compare the level and characteristics of core competency of registered nurses in different working years in order to supply evidence to establish contrapuntal training protocol.Methods "The Competency Inventory for Registered Nurse scale"(CIRN,by LIU Ming)was distributed to investigate the core competency of registered nurses,the data underwent analysis.Results The overall score of core competency level was (174.11±31.89),the score of the nurses with 16～20 years of working experience was the highest,while the score of nurses working for 1～5 years was the lowest.The core competency varied with working years,evident difference existed in different dimensions and total scores.Conclusions The overall core competency is at the upper middle level for registered nurses from five tertiary level first-class hospitals in Liaoning Province.They are competent enough to provide health care.With the increasing length of working time,nurses' core competency level will strengthen gradually.

OBJECTIVE: To prepare solid supersaturatable self-emulsifying drug delivery system of vinpocetine(VIN-S-sSEDDS) and to study its characteristics in vitro and in vivo.METHODS: VIN-S-sSEDDS was prepared by spray drying using hydroxypropyl methyl cellulose(HPMC) as supersaturation promoter and dextran-40 as solid carrier.VIN-S-sSEDDS was compared with conventional self-emulsifying drug delivery system containing vinpocetine(VIN-SEDDS) in respects of particle size,in vitro dissolution and bioavailability in rats(ig.).RESULTS: The particle size of VIN-S-sSEDDS(58.78 nm) was smaller than that of VIN-SEDDS(65.12 nm).The accumulative dissolution of VIN-S-sSEDDS within 2 h(88.7%) was higher than that of VIN-SEDDS(58.2%).The bioavailability of VIN-S-sSEDDS in rats(2.30) was higher than that of VIN-SEDDS(1.63).CONCLUSION: Prepared VIN-S-sSEDDS could apparently improve the dissolution and bioavailability of VIN,and it is superior to conventional self-emulsifying preparation.

Purpose To evaluate the clinical and pathological features of extramammary Paget’ s disease ( EMPD) and to investigate the related prognostic factors. Methods The clinical and pathological data of 30 patients with EMPD were reviewed retrospectively. The HE slides in the file were rechecked. Immunohistochemical stains were performed on archival paraffin-embedded sections with En-Vision method in 20 cases. Follow-up data were recorded. The relationship between the clinicopathological parameters and prognosis was statistically analyzed. Results Among the 30 patients, there were 26 males and 4 females, aged from 53 to 88 years with median age 70. Macroscopically, typical presentations of EMPD were eczematoid lesions. Microscopically, Paget’s cells were distributed sin-gly or in groups ( as glandular or nests patterns) within the epidermis. Immunohistochemical stains showed that Paget’ s cells were pos-itive for CK7, and negative for CK5/6 and p63. Follow-up data were available in 23 cases, 8 cases recurred resection, among them, 6 patients had positive resected margin and 4 died. The recurrent rate and mortality between the groups of dermal invasion and no der-mal invasion (P<0. 01 and P<0. 05), the groups of lymphatic metastasis and no lymphatic metastasis (P<0. 01), and the groups of positive and negative resected margin (P<0. 01 and P<0. 05) were statistically different. There were no statistically different with age and extent of lesion (P>0. 05). Conclusions CK7 is a sensitive and specific marker of Paget’s cells. Dermal invasion, lymphatic metastasis and positive resected margin are poor prognostic factors in EMPD.

Objective: To discuss the role of clinical pharmacists played in the pharmaceutical care for osteomyelitis patients. Methods:Clinical pharmacists participated in the treatment for a special patient with osteomyelitis. Taking the disease features, medi-cal history, adverse drug reactions into account, clinical pharmacists provided consultant opinions for establishing and adjusting the ap-propriate therapeutic regimens and individualized pharmaceutical care. Results:The drug treatment regimens for the patient were safe, effective and rational. By the individualized pharmaceutical care, clinical pharmacists were able to find the problems in the drug treat-ment and implement the efficient solutions. Conclusion: Clinical pharmacists show their own advantages in individual pharmaceutical care, and play an important role in improving the rational drug use.
