BACKGROUND:In various clinical treatments of soft tissue defects, vacuum sealing drainage technology can effectively control wound infection, shorten the treatment time, and accelerate wound healing. OBJECTIVE:To further understand the features and characteristics of hydrated ethanol polyethylene foam vacuum sealing drainage treatment, and compare the treatment effects against soft tissue defects with the conventional dressing change treatment. METHODS:A total of 140 cases of large soft tissue defects were divided randomly into two groups. Observation group received hydrated ethanol polyethylene foam vacuum sealing drainage treatment, while control group was treated by conventional dressing change. The degree of pain relief during treatment, the family satisfaction, the survival rate of first skin-grafting, the time needed before skin-grafting, the hospitalization time, the number of operations, the readmission rates, the complication rate and other clinical effectiveness indicators were compared between the two groups. RESULTS AND CONCLUSION: In the observation group, visual analog scale scores decreased 5.76±0.68, in the control group visual analog scale score decreased 2.85±0.53, with significant differences between the two groups (P < 0.05), and family satisfaction degree of the observation group was higher (P < 0.05). The survival rate of first skin-grafting of the observation group was higher than the control group (P < 0.05), the time needed before skin-grafting, the hospitalization time, the number of operations, the readmission rates, and the complication rate were lower than the control group (P < 0.05). The results showed that, compared with conventional dressing change treatment, hydrated ethanol polyethylene foam vacuum sealing drainage has advantages of light pain, short treatment time, low rate of complications, and high efficacy.

Objective To find out the correlation between MMP-13 and clinicopathological parameters of breast cancer and identify clinical significance of MMP-13 overexpression on overall survival of breast cancer.Methods Immunohistochemistry was performed on paraffin-embedded tissue microarray containing 159 tissue dots from breast cancer patients.The intensity and the extent of IHC were scored by pathologists blind to clinicopathological parameters of the specimens.Different expression profiles of MMP-13 in breat cancer tissues and paraneoplastic tissues,and correlation between MMP-13 and breast cancer clinicopathological parameters were analyzed for statistical significance respectively.The impact of MMP-13 overexpression on overall survival of breast cancer.Results MMP13 expression were significantly higher in breast cancer tissues(54.4％) than in their corresponding paraneoplastic tissues(27.5％)(P =0.003).Expression of MMP-13 in breast cancer positively correlated with lymphma node metastasis(r =0.257,P =0.006),clinical TNM classification (r =0.310,P =0.001),HER2 expression (r =0.192,P =0.041).However,no significant correlation were oberserved between MMP-13 expression and tumor size,MMP-13 expression and tumor grade,MMP-13 expression and ER expression,MMP-13 expression and PR expression respectively.Conclusions Overexpress of MMP-13 is more common in breast cancer tissues than in their corresponding paraneoplastic tissues,and is an independent prognosis indicator of breast cancer.

Objective To observe the application effect of comfortable nursing in percutaneous coronary intervention for patients with acute myocardium infarction.Methods 112 patients with acute myocardium infarction receiving the treatment of percutaneous coronary intervention were randomly divided into the observation group and the control group,each group including 56 cases.The control group was given conventional nursing,and the observation group was given comfortable nursing.Hospitalization time,nursing satisfaction degree,psychological status before and after treatment and life quality for patients in two groups were evaluated.Results The nursing satisfaction degree,nursing effect and life quality for 56 patients in the observation group were higher evidently than those in the control group.And the average hospitalization time of the observation group was lower than that of the control group.The comparison between two groups had statistical significance.Conclusions Comfortable nursing in percutaneous coronary intervention for patients with acute myocardium infarction can evidently improve medical quality,and can provide strong guarantee for the life and safety of patients.

Purpose To investigate the clinicopathological changes, immuniohistochemistry and molecular genetics phenotypic charac-teristics of the alveolar soft part sarcoma ( ASPS) . Methods 16 cases of ASPS were studied with clinicopathological, cytochemistry technique and immunohistochemical staining, two cases of ASPS were studied by FISH. Results There were 6 males and 10 females with the age 8~58 years (median age 31. 7 years). The tumors were located at limbs, shoulder and back, tongue, vocal cords, lung, cervix, and ureter. The clinical manifestations of the patients was a slowly growing mass. Histopathologically the tumor showed typical organ-like or acinar-like structure with sinus-like blood vessels and the fibrous septa formation. Sometime the clear or abundant eosino-philic granular cytoplasm of the tumors were obvious. The tumor cells had a crystalline substance formation by PAS staining. The tumor cells were positive for TFE3 and Cathepsin K by immunohistochemical staining. The ASPL-TFE3 gene fusion detection of tumor cells were present. Conclusion ASPS often located on the limbs of young patients. It may misdiagnosed as malignant epithelial tumors, primary or metastatic adenocarcinoma and paraganglioma when the tumor locate on a rare anatomical parts or an organs, such as tongue, vocal cords, cervix, ureter, etc. It is valueable that the typical alveolar-like structure of the tumor and the expression for TFE3 and Cathepsin K for the pathological diagnosis of ASPS. It is an important indicator that the ASPL-TFE3 gene fusion detection by FISH for the tumor.

OBJECTIVE:To study the adsorbability of plastic transfusion bottle and infusion set to diazepam. METHODS:With the reference of plastic-bottled 5% glucose injection,HPLC was used to determine the changes of mass concentration of diazepam adding into plastic-bottled 5% glucose injection at different time;disposable plastic infusion set was connected to simulate intrave-nous infusion and determine the changes of mass concentration of diazepam in the liquid effluent at different time. RESULTS:The mass concentration of diazepam in glass infusion bottles group was higher than in plastic transfusion bottles group. The adsorbabili-ties of solutions showed the strongest at the time of 15-20 min. The mass concentration of the effluent liquid from the glass bottle group was about 80% of the original concentration and plastic bottle group was about 67%. As the time went on,the adsorbability was gradually saturated at 60 min and the concentration rose again;the mass concentration of the effluent liquid from the glass bot-tle group returned to 95%of the original concentration at 80 min and the plastic bottle group was about 75%of the original concen-tration. CONCLUSIONS:Both plastic infusion bottle and infusion set have strong adsorbability to diazepam. It is suggested that the dosage of diazepam should be increased by 25% to 33% while plastic-bottled 5% glucose injection is used as solvent for intrave-nous drip.
