Pelvic fracture is a complex fracture,unstable pelvic fracture needs surgical operation.Early open reduction and internal fixation would be benefit for functional rehabilitation,help to reduce mortality,blood loss and late complications.Surgical approaches include iliac-groin approach and Kocher Langenbeck approach.There are many iatrogenic injuries of surgery,including vessels,nerves and viscerals injuries.Once the injuries happened the consequences are very serious.So,preventing these iatrogenic injuries is crucial.Only if we are familiar with surgical approach and research the clinical anatomy much more,we could reduce the occurrence of iatrogenic injury utmostly.

Objective To determine the protein and mRNA levels ofinterleukin-17 (IL-17) and the proportion of Th17 cells in the peripheral blood of patients with systemic lupus erythematosus (SLE) and their clinical significance is analyzed. Methods Twenty-five hospitalized SLE patients were recruited and twentytwo healthy volunteers were enrolled as normal controls. Plasma protein and mRNA of IL-17 in the peripheral blood were measured by enzyme-linked immunosorbent assay and real time-PCR respectively. Flow cytometric assay was used to analyze the percentage of Th17 cells in SLE patients. The relationship between IL-17/Th17 cells and clinical or laboratory parameters of SLE patients was explored. Students' t-test and Spearman's correlation was used to evaluate the relationship between mRNA level and inflammatory parameters. Results The plasma concentration and mRNA level of IL-17 was significantly elevated in SLE patients as compared to the normal controls (P＜0.05). The percentage of Th17 cells in patients with SLE was higher than that of normal controls and was significantly increased in more active SLE patients and SLE with nephritis than less active SLE and SLE without nephritis (P＜0.05). Both plasma levels of IL-17 and the proportion of Th17 cells were positively correlated with SLEDAI (r=0.681, P＜0.01; r=0.426, P=0.034). Conclusion Plasma IL-17 protein and mRNA expression level and the percentage of Th17 cells in SLE patients are all significantly elevated and the close relationship between IL-17/Th17 cells and disease activity suggests that IL-17/Th17 may play an important role in the pathogenesis of SLE.

[Objective]To construct arecombinant eukaryotic expression plasmid carrying human BMP-7 gene which was transfected into bone marrow stromal cells(BMSCs) in vitro and expressed.[Method]Clone human BMP-7 cDNA from a Chinese woman placenta was recombinanted with plasmid pcDNA3.1,to construct eukaryotic expression carrier of recombinaut pcDNA3.1-hBMP-7.The BMSCs were isolated from rabbit bone marrow and cultured in vitro.They were divided into three groups: pcDNA3.1-hBMP-7 transduced group;pcDNA3.1 transduced group;untransduced group.The expression of hBMP-7 was detected by RT-PCR,Immuneohistochemistry.ALP,Collogen,Osteocalcin production were detected.[Result]The pcDNA3.1-hBMP-7 transduced BMSCs expressed hBMP-7 at both mRNA and protein levels.ALP activity was detected in pcDNA3.1-hBMP-7 transduced cells from day 2 to day 10,peaking on day 8.Collogen,osteocalcin production were elevated significantly too(P

Objective To determine the protein and mRNA levels of interleukin-17 (IL-17) in the peripheral blood of patients with systemic lupus erythematosus (SLE), and to analyze the relationship between IL-17 and disease activity. Methods Twenty-six hospitalized SLE patients and twenty-one normal controls were studied. Plasma protein and mRNA of IL-17 in peripheral blood were measured by ELISA and Real-time RT-PCR respectively. Results IL-17 level and its mRNA level increased in SLE patients compared with that in normal controls. Plasma concentration of IL-17 showed a significant positive correlation with SLEDAI score and anti-dsDNA antibody level, and a significant negative correlation with serum C3 level. Conclusions Plasma IL-17 protein and mRNA expression level in SLE patients increased significantly and had close relationship with disease activity, which might suggest that IL-17 play an important role in the pathogenesis of SLE.

Medical and health equipment are rapidly developing in the direction of intelligence and portability. As a representative of them, wearable devices are playing an more and more important role in medical service. To this end, this review discussed the development process of wearable devices, and defined the concept of wearable devices. The existing wearable devices were divided into four categories according to their shapes: hand wear, head wear, lower limb wear and trunk wear. The application of them in medical service were particularly introduced. The 4 future development trends of wearable device, included adding fashionable element, focusing on a particular area, new interactive model and invisible portability, were analyzed and reviewed. Based on above analysis, we could got a comprehensive understanding for the application of current wearable device in medical treatment, and could hold the development direction of wearable device in medical treatment of hospital. While, for above products, there were some differences in technique level between domestic manufacturer and developed country, and there is a larger potential in the relevant products and arithmetic aspects.

Objective To resolve the problem of low speed and high failure rate of SMS.Methods The SMS module was separated,and the appointment registration system and SMS device were taken apart.Results The separate SMS platform for appointment registration system was established.Conclusion The response speed of the appointment registration system is enhanced greatly.

Objective To measure and conduct statistic analysis of normal eyes by Pentacam. Methods Two hundred and twenty-one healthy people (442 eyes) underwent examinations of Pentacam, and they were divided into 5 groups by age: <40 years old group (50 people, 100 eyes), 40-49 years old group (50 people, 100 eyes), 50-59 years old group (50 people, 100 eyes), 60-69 years old group (50 people, 100 eyes) and >70 years old group (21 people, 42 eyes). Results With the increase of age, there were significant differences in chamber volume, chamber angle and anterior chamber depth among age groups (P<0.05). In elder age groups, there were significant differences in these parameters between males and females (P<0.01). Conclusion Anterior segment parameters are significantly correlated with age. After 60 years old, the anterior segment parameters become significantly different with gender.

Objective To explore the changes and significances of serum leptin and interleukin-1?(IL-1?)before and after treatment with risperidone in children with schizophrenics.Methods Thirty-one cases with first-episode children with schizophrenia were chosen in patient group.Their body weight and height were measured before and 8 weeks after treatment with risperidone to calculate the body mass index(BMI),and their fasting serum leptin and IL-1? were assayed radio-immunity method.Thirty-one healthy controls were measured at the same time.Results BMI and the level of serum leptin in patients of post-treatment increased significantly compared with those of pre-treatment(all P

Objective To investigate the amount of CD4+CD_(25)~+ regulation T cells(Tr cells) and the expression of Foxp3 in peripheral blood in children with acute idiopathic thrombocytopenic purpura(AITP),and analyze the relationship between CD4+CD_(25)~+ Tr cells and the immunopathogenesis of AITP.Methods CD4+CD_(25)~+ Tr cells were detected by flow cytometry in peripheral blood from AITP children and health children.Besides,related cytokine in peripheral blood were assigned by enzyme linked immunosorbent assay(ELISA).The expression of Foxp3 were detected by reverse transcriptase-polymerase chain reaction(RT-PCR).Results CD4+CD_(25)~+ Tr cells decreased obviously in peripheral blood in children compared with that of control group [(2.83?1.05)% vs (5.07?0.59)%,P
