Objective To explore the nursing effect evaluation of vacuum sealing drainage based latissimus dorsi bridge free skin flap to repair refractory wound. Methods Thirty-seven cases of patients with intractable wounds were chosen as the observe group from January 2009 to January 2012, and 26 cases accepting the traditional way of wound care with intractable wounds were selected as control group from January 2006 to December 2008. Control group adopt conventional methods wound and the observation group accepted VSD accessories line wound negative pressure closed drainage before the wound phase 2 latissimus dorsi bridge free skin flap repairment. After treatment, the dressing time, interval and dressing change, the time of hospitalization were observed, and the nursing effect were compared after skin flap to repair for 8 days and 16 days between patients of two groups. Results The dressing time and hospitalization days in observation group after treatment were significantly less than that in control group ( <0.05), the number of dressing have significantly shortened compared with control group ( <0.01), and the dressing change interval in control group had significantly difference ( <0.01) . The effect of 2 patients in control group after skin flap to repair was poorer, but the observation group did not appear significant necrosis. Compared the good rate of two groups, the observation group patients was significantly higher than control group ( <0.01) . The therapy good rate of observation group was significantly better than that of control group (<0.01) . Conclusion The negative pressure closed drainage based ascending latissimus dorsi bridge free skin flap repairment has contributed to cure the refractory wound recovery significantly.

[Objective] To discuss the cure effect of conjunctiva valve combined with tarsorrhaphy and standardized medication on refractory keratohelcosis. [Method] Choose 37 cases with 37 eyes of the disease above, divide them into control group, n=17, and observation group, n=20; the control one take conjunctiva valve combined with tarsorrhaphy and routine medicine intervention; other group, standardized drug intervention instead of routine medicine. Observe the therapeutic effect after 6m. [Result] In observation group, 18 cases were cured(90%), 2 better(10%); for other group, they were 9(52.9%) and 4(23.5%) respectively, and 4 cases had no effect(23.5%). Comparing both cure effects, the difference had statistical meaning. [Conclusion] The conjunctiva valve combined with tarsorrhaphy could markedly improve the cure effect if intervened with standardized drug.

The peak plantar pressure and percentage of peak time were evaluated using the Foot scan Plate System in the walking patients without footwear. Diabetic patients with peripheral neuropathy have abnormal plantar pressure distribution, with higher peak plantar pressure in the third and fifth caput of metatarsus and hallux, and longer percentage of peak time.

Aim To investigate the effect of Dicranostiga Leptodu (Maxim) Fedde (DLF) on experimental liver injury induced by Calmette Guerin bacillus vaccine (BCG) and Lipopolysaccharide (LPS) in mice. Methods Experimental liver injury was induced by Calmette Guerin bacillus vaccine and Lipopolysaccharide in male mice by injecting via tail vein (50 ?g?kg -1 ), and administering LPS (10 ?g?mouse -1 ) 10 d later. Therapeutic groups were given respectively with DLF (0 5,1 0,2 0 g?kg -1 ) before administration of LPS. The level of ALT, AST and LDH and the concentration of ALB and GLB in serum were measured by automatic biochemistry analyzer, and MDA in liver plasma was measured by TBA method and the level of SOD was measured by pyrogallol auto oxidation method. Pathological morphological changes in liver tissue were observed. Results The three experimental groups were found with significant decrease in the elevation of serum GPT and LDH level and the content of MDA in the liver plasma. The liver tissue damages were also ameliorated. Conclusion DLF has protective effect against the experimental liver injury induced by BCG and LPS in mice.

Objective:To investigate the feasibility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)parameters in differentiating musculoskeletal tumors with different behaviours of pathological findings before therapy.Methods:A total of 34 subjects of musculoskeletal tumors were in-volved in this retrospective analysis.DCE-MRI was performed using a fat-saturated 3 D VIBE (volumetric interpolated breath-hold exam)imaging sequence with following parameters:FA,10 degree;TR/TE, 5.6/2.4 ms;slice thickness,4.0 mm with no intersection gap;field of view,310 mm ×213 mm;ma-trix,256 ×178;voxel size,1 .2 mm ×1 .2 mm ×4.0 mm;parallel imaging acceleration factor.The ac-tuation time for the DCE-MRI sequence was 255 s with a temporal resolution of 5 s and 40 image vo-lumes.Using pathological results as a gold standard,tumors were divided into benign,borderline and malignant tumors.Toft’s model was used for calculation of Ktrans (volume transfer constant),Ve (extra-vascular extracellular space distribute volume per unit tissue volume)and Kep(microvascular permeability reflux constant).Those parameters were compared between the lesions and the control tissues using paired t-tests.The one-way analysis of variance was used to assess the difference among benign,border-line and malignant tumors.P values <0.05 difference was statistically significant.Results:Based on the WHO Classification of Tumours of Soft Tissue and Bone(2012)criteria,34 patients were divided into three groups:1 1 for benign tumors,12 for borderline tumors,and 1 1 for malignancies.Compared with control tissues,Ktrans and Kepshowed no difference,but Ve was increased in benign tumors,Kep showed no diffe-rence,butKtransandVewereincreasedinborderlinetumors, Ktrans,KepandVewereincreasedin malignant tumors.Ktrans(P<0.001 )and Kep (P<0.01 )were significantly higher in malignant tumors than in benign and borderline tumors,but did not show any difference between benign tumors and border-line tumors.Ve was significantly higher in malignant tumors than in benign (P<0.05),but did not show any difference between malignant and borderline tumors,benign tumors and borderline tumors (P >0.05 ).Conclusion:DCE-MRI technique is useful to evaluate the pathological behaviour of musculoske-letal tumors.The quantitative analysis of DCE parameters in conjunction with conventional MR images can improve the accuracy of musculoskeletal tumor qualitative analysis.

Objective To analyze the clinical and imaging features of pulmonary metastasis of giant cell tumor of bone for clinical diagnosis and treatment.Methods Five patients with histologically proven pulmonary metastasis from giant cell tumor of bone were reviewed,the imaging features and the progression of the pulmonary metastasis were evaluated.Results The first operation of primary tumor was curettages and then local recurrence was seen in all 5 cases.The interval to metastasis ranged from 5 to 26 months.Pulmonary metastasis was diagnosed by chest radiographs in 4 cases and CT in all 5 cases.The imaging findings included solitary solid nodule (n =1),multiple solid nodules and mass (n =5),multiple groundglass nodules (n =1) and complex form (n =2).The dynamic follow-up CT findings showed spontaneous regress nodules (n =1),metastasis occurring again 19 months after surgery of solitary nodule (n =1),some solid nodules unchangable for a long time in 3 patients with multiple nodules.Conclusions The dynamic follow-up CT findings of pulmonary metastasis of giant cell tumor of bone are specific.The regular follow-up could play an essential role in early detection and prognosis of pulmonary metastasis within 2 years after primary tumor diagnosed.

Objective To analyze the CT and magnetic resonance imaging (MRI) manifestations of the pelvic osteosarcoma. Methods The CT and MRI manifestations of 15 cases with pelvic osteosarcoma from January, 2013 to December, 2015 proved by histology were ret-rospectively analyzed. Results There were 10 males and 5 females in them. The median age was 27.0 years. Ilium was involved in 11 cases. A mixed lytic/sclerotic pattern of bone destruction was found in 11 cases, and the sclerotic type in 2 cases, the osteolytic type in 2 cases. Ra-dial periosteal reaction was found in 5 cases and immature bone formation in 8 cases. Soft tissue masses were seen in 13 cases. MRI showed enhancement in 15 cases and the CT showed no enhancement in 2 cases with sclerotic type. Conclusion The typical imaging manifestations of pelvic osteosarcomainclude mixed lytic/sclerotic appearance, radial periosteal reaction, soft tissue masses and immature bone formation.

Objective To compare the efficacy and adverse effects of 5 days' and 7 days' course of combination chemotherapy regimen HA in the treatment of chronic phase of chronic myelogenous leukemia (CML-CP). Methods 18 cases of CML-CP had received 5 days' course of combination chemotherapy regimen HA including homoharringtonine 4 mg/d and cytarabine 200 mg/d for 5 days. At the same time,another 18 patients diagnosed as CML-CP who were given 7 days' course of HA regimen including homoharringtonine 4 mg/d and cytarabine 200 mg/d for 7 days were compared on the efficacy including peripheral white blood cells, spleen size and cytogenetic responses and adverse effects. Results The complete remission(CR) rate was 50.0 % and 61.1 % in 5 days' and 7 days' treated groups, respectively (P >0.05). The incidence of severe bone marrow suppression in 7 days' group(16.7 %) was higher than that in 5 days' group(0)(P <0.05). Conclusion The 5 days' course of combination chemotherapy HA regimen is same as 7 days' course of HA regimen about their curative effects in CML-CP. But the incidence of severe bone marrow suppression in 7 days' group(16.7 %) was higher than that in 5 days' group (0).
