Objective To describe the operative procedures.fracture patterns and clinical outcomes of treatment of posterior column tibial plateau fractures.Methods From February 2005 to August 2006,36 patients with posterior column tibial plateau fracture were operated on.Twenty patients were treated with open reduction and buttress plate fixation via a posterior approach.They were 13 males and 7 females,with a mean age of 38.5(ranging from 29 to 52)years.The other 16 patients were operated on via anterior plus posterior approaches.They were 11 males and 5 females,with a mean age of 37.3(ranging from 27 to 49) yeam. Results All were followed up for an average of 14.5(ranging from 12 to 15)months.All frac- tures got united with an average radiographic bone union time of 15.7(ranging from 11 to 16)weeks and an average full weight-bearing time of 17.6(range from 13 to 21)weeks.The mean HSS(The Hospital for special surgery)score of all these patients at 12 months postoperatively were 83.4(ranging from 68 to 92). There were 1 case of inferior medial genicular vessel injury during the operation,1 wound dehiscence and 1 partial incision necrosis postoperatively which were all eventually healed with conservative treatments.Three cases of numbness within the posterior lower part of the calf occurred postoperatively.No screw toggle,slide, dislodging or fixation failure was found during follow-up.There were no significant differences both between TPA and PA on radiographies and between immediately after operation and 12 months psstoperatively. Conclusion Open reduction and internal fixation with buttress plates via a posterior or anterior plus posterior approaches is appropriate for treatment of posterior column tibial plateau fractures.

Covered in the paper is the development of the hospital's surgical information acquisition system during the healthcare reform and upgrading of its performance assessment scheme.Such a system is designed to precisely collect surgery scheduling, daytime surgery, and outpatient surgery workload, conducive to developing a performance assessment scheme based on surgery workload, motivating medical workers, and improving quality of care.

Tumor surface antigen human epidermal growth factor receptor 2 (Her2) is a type I receptor tyrosine kinase, which belongs to human epidermal growth factor receptor family. Her2-overexpression is associated with tumorigenesis and metastasis. Due to significant clinical effects, Her2-targeted cancer therapy especially therapeutic antibody has become the hot spot in the field of cancer treatment. Anti-Her2 antibody drugs include monoclonal antibodies, antibody-drug conjugates, bispecific antibodies and emerging "two in one" antibody. Based on structure and function of Her2, this review focuses on recent advances in active mechanisms and clinical researches of these antibodies.

Objective:To investigate the resting energy expenditure of children with mechanical ventilation and analyze their association with anthropometric indicators (height, weight, and body mass index) and serum protein markers (pre-albumin, albumin, transferrin, and retinol).Methods:An observational study was held in Pediatric Intensive Care Unit(PICU) of Beijing Children′s Hospital, Capital Medical University, from August 2015 to April 2016.Critically ill children with mechanical ventilation were enrolled in this study.Inclusion criteria were as follows: (1)pediatric critical illness score<90 scores or meet the United States PICU admission criteria; (2)age>29 days, <18 years old; (3)mechanical ventilation>24 hours; (4) tidal volume >60 mL.Resting energy expenditure was determined by US Med Graphic Company CCM/D energy metabolism test system.German Famed Zywier intensive care bed with weight scale weighing, uniform measuring bed or meter measuring height, automatic biochemical analyzer and radioimmunoassay was adopted for the determination of albumin, pre-albumin, transferrin, retinol binding protein.SPSS 20.0 software was applied for carrying out Pearson line analysis correlation. Results:A total of 68 children were included in the study, including 36 males and 32 females, body weight (22.34±14.89) kg, height (122.23±14.89) cm, resting energy consumption (784.63±278.25) kcal(1 kcal=4.185 kJ), and resting energy consumption per kilogram of body weight (48.80±31.26) kcal.In anthropometric indicators, resting energy expenditure was significantly positively correlated with height, body weight ( r=0.764, 0.734, all P<0.05), a low positive correlation with body mass index( r=0.396, P<0.05). In serum proteomics, resting energy expenditure was negatively correlated with pre-albumin, transferrin ( r=-0.318, -0.282, all P<0.05), and a moderate negative correlation with retinol protein ( r=-0.505, P<0.05), while without correlation with albumin ( r=-0.075, P>0.05). Conclusions:The height, weight and serum proteomics of children with mechanical ventilation may affect resting energy expenditure.

BACKGROUND: Studies regarding synthesizing composite bone repair materials with organic macromolecules as mineralizers template are the hot research spot. However, reports concerning using agar as bone repair materials are few. OBJECTIVE: To synthesize a novel agar-hydroxyapatite composite material, and to evaluate its physical and chemical properties as well as cytocompatibility.METHODS: ①A certain amount of the non-nano-hydroxyapatite in hydrochloric acid solution was added into a certain amount of agar sol, and the reaction system was adjusted with PH value of 7-8. And then the precipitate was lyophilized to obtain the composite of agar-hydroxyapatite.②The third generation of rat bone marrow stromal cell (BMSC) was co-cultured with agar-hydroxyapatite. And the growth of cells was observed at days 1, 3 and 5 after culture. RESULTS AND CONCLUSION: The results of X-ray diffraction patterns, Fourier transform infrared spectrometer (FTIR), thermal analyzer, transmission electron microscope, and scanning electron microscope showed that agar could manipulate the growth of hydroxyapatite, and hydroxyapatite nanocrystals was equably formed on the agar-fibers with high porosity. The BMSC grew well in the composite and form a clear cytoskeletal at days 3 and 5 after culture. The results reveal that agar-hydroxyapatite composite has good physical and chemical properties and cytocompatibility.

Objective To evaluate the clinical effects of platelet-rich plasma in treatment of DeepⅡburn wounds. Methods Sixty eight cases of inpatients with Deep Ⅱburns were selected, whose age were from 1 to 65 years and their burn areas were between 5%~62%of total body surface area (TBSA). Deep gradeⅡburn of each sample was divided into two parts. Part A was the treatment group and part B was the control group.The burn wounds in the treatment group were treated with platelet-rich plasma and the counterpart in the control group were treated with SD-Ag. Healing time ,recovering rate and the frequency of dressing changes,frequency of changing the most innerlayer gauze and the rate of wound infection were also analyzed. Finally the laboratory abnormalities and adverse effect were monitored regularly. Results The healing time of the treatment group (16.5±3.1 ) d was shorter than that of the control group (19.5±3.8 ) d. The recovering rate of the treatment group was higher than that of the control group on the 14th and 17th day after treatment. There were statistically sig?nificant differences between these two groups (P<0.05). After two weeks’treatment, the internal and external dressing per?meability into wet gauze layers were 20.6 ± 1.7, which were significantly decreased than that in the control group 23.3 ± 5.9. The frequency of dressing changes was(7.2±1.1)times in treatment group versus(9.2±1.4)times in control group and the frequency of changing the inner most layer gauze was( 2.3±0.6)times in the treatment group versus(5.3±1.3)times in con?trol group. There were 5 inflammation reaction cases in the treatment group, but 13 cases in the control group. However, there was no statistic significance between the two group in the outcomes of bacterial culture, the laboratory abnormalities and the adverse effect. Conclusion Platelet-rich plasma can remarkably shorten the healing time,improve healing rate,re?duce frequency of dressing change and promote wound healing for deepⅡburn wound. PRP is a potential safety reagent in treating deepⅡburn wound.

The construction of a network resource data base for clinical skill teaching aiming at sharing excellent teaching resources was completed by integrating all kinds of teaching resource including characters,eourseware,pictures,cartoons,videos and examination questions,etc.In view of the generally weak situation of the current domestic education resource data base construction,the contents,guiding ideology,principle,object,orientation,function and the management mechanism of the network resource data base construction were devised for clinical skills teaching.Suggestions for specific ideas and construction problems were proposed to promote the construction and optimization of the network resource database for clinical skills teaching.
