Objective To discuss the value of preoperative digital design of struetund bone graft for acetabular wall defects. Methods The . dieom data from spiral CT scans were imported into Mimics 10.0 to build the 3D solid model of the pelvis of an old female patient with left acetabular wall defects. The 3D solid model of the defect area was built by Mirror and 3D mask editing. A simulated bone graft was conducted on the 3D model by segmentation and trimming according to the data measured on the reconstructed model. Results The reconstructed 3D model of the patient's pelvis could be presented in different colors, transparenees, or combinations of interested tissues. The acetabular wall defects could be visualized very clearly at different angles. The geometric data of the bone graft could be measured to ensure the bone graft would fit the defects accurately. Conclusion Preoperative digital design based on 3D com-puterized reconstruction of acetabular wall defects may provide a valuable aid to clinical treatment, because it is a simple, rapid, and accurate method of increasing the fitness of bone graft and the defects,

Objective To compare the values of the mangled extremity syndrome index (MESI), the mangled extremity severity score (MESS) and the limb salvage index (LSI) in deciding amputation or salvage in the management of the mangled extremity syndrome (MES). Methods Clinical data of 353 MES patients including 95 with amputation and 258 with salvage admitted in recent eight years were retrospectively evaluated by using MESI, MESS and LSI, the value of which in deciding amputation or salvage was assessed with receiver operating characteristic ( ROC ). Results There was statistical difference in aspect of mean scores of three grading systems between patients with amputation or salvage (P＜0. 01). For MESI, MESS and LSI, the sensitivities was 89.47%, 85.26% and 83.15% respectively, the specificities was 100%, 96.89% and 96.12% respectively, the coincidence was 97.16%,93.76% and 92.63% respectively, the areas under ROC curves was 0. 924, 0905 and 0. 861 respectively and the cut-off points were equal or over 20, 7 and 6 respectively. Conclusions Three scoring systems are all highly capable of predicting early amputation or not in MES management. The MESI is recommended as a quantitative criterion for determining amputation or salvage.

Objective:To evaluate the clinical efficacy and safety of topical hydrocortisone butyrate cream combined with a skin cream dressing in the treatment of mild to moderate atopic dermatitis (AD) .Methods:From July 2019 to June 2020, a randomized, open, controlled clinical study was conducted in Beijing Friendship Hospital, Capital Medical University. Sixty patients with mild to moderate AD were enrolled into this study, and randomly divided into 2 groups by using a random number table. The patients in test group topically applied a skin cream dressing (trade name FORENéE) followed by hydrocortisone butyrate cream, and those in control group topically applied the vehicle of the cream dressing followed by hydrocortisone butyrate cream. The treatment was carried out twice a day for 4 weeks. Visits were scheduled at baseline and after 2 and 4 weeks of treatment, efficacy was evaluated, and adverse reactions were recorded. Repeated measures analysis of variance and chi-square test were used to compare efficacy and safety between the 2 groups.Results:Before treatment, there was no significant difference in eczema area and severity index (EASI) , visual analogue scale (VAS) or investigator global assessment (IGA) scores between the 2 groups (all P < 0.05) . After 2 and 4 weeks of treatment, the response rate was significantly higher in the test group (86.67%[26/30], 93.33%[28/30], respectively) than in the control group (60.00%[18/30], 73.33%[22/30]; χ2=5.455, 4.320, respectively, both P < 0.05) . After 2 and 4 weeks of treatment, the remission rate of pruritus ( χ2=4.320, 4.022, respectively, both P < 0.05) and treatment success (IGA 0/1) rate ( χ2=6.667, 15.429, respectively, both P < 0.05) were significantly higher in the test group than in the control group. There was no drug-related adverse reactions in the 2 groups. Conclusion:Hydrocortisone butyrate cream combined with FORENéE skin cream dressing is safe and effective in the treatment of mild to moderate AD, and can be applied to clinical practice.

Objective To evaluate the clinical efficacy and safety of topical glucocorticoids combined with a moisturizer containing antimicrobial peptides in the treatment of persistent localized eczema. Methods A total of 60 patients with localized eczema were divided into 2 groups. Group 1 topically applied Fuqing gel (an antimicrobial dressing) and hydrocortisone butyrate cream twice a day for 2 weeks, and group 2 topically applied the vehicle of Fuqing gel and hydrocortisone butyrate cream twice a day for 2 weeks. Recovered patients were followed up once every 4 weeks for 12 weeks. Bacterial culture was performed for 5 patients with suspected local Staphylococcus. aureus infection, including 3 patients in group 1 and 2 in group 2, before and after the 2?week treatment. Therapeutic effects were evaluated and compared between the two groups. Results Compared with group 2, group 1 showed a signifi?cantly higher response rate after 1?week treatment(χ2 = 5.455, P < 0.05), but significantly lower eczema area and severity index(EASI)scores after 1? and 2?week treatment(both P < 0.05). Before the treatment, S. aureus was detected in all the 5 patients. After 2?week treatment, S. aureus was undetected in all the 3 patients in group 1, but was still detected in the other 2 patients in group 2. The treatment was rated as ineffective in none of 7 recovered patients in group 1 during the 12?week follow up, but in 2 of 5 recovered patients in group 2 at week 10. Conclusion Fuqing gel combined with glucocorticoid ointment is safe and effective for the treatment of localized eczema, and can be applied in clinic.

TWO average expense control(TAEC) is the method that the hospital want to control the increasing breadth of medicine expense by limiting the total expense which include both clinic expense and hospitalize expense.TAEC will fake great help to improve the relationship of docfor and patient and to promote the hospital work.But the method of TAEC will also to be optimize further.

It is important to put the professional quality training into the course of specialties in higher vocational education of the Rehabilitation Therapy, including the thinking mode of rehabilitation medicine, team working, communication, and personality of love, patience and responsibility and so on.
