With the progress of science technology,the 3D technology has raised comprehensive attention for its application value in medical field,especially in the orthopedic field.It has been mainly used before complicated orthopedic surgeries,and several studies have focused on 3D duplicated materials used in the treatment of bone defect.However,there are seldom studies about the 3 D technology used during surgeries,such as whether it is possible to 3D print internal fixation materials of bone fracture (the materials have biodegradability and excellent biomechanical characteristics),which can not only promote the healing of fracture,but also reduce the pain of second surgery for the patient.This paper reviews and summarizes the exploration of foreign and domestic scholars about the application value of 3 D printing technology used in complicated bone fracture,and proposes a forecast to the developing trend of the technology used in future orthopedic surgeries.

Objective To explore the trend of mortality and years of life lost due to Esophageal Cancer in residents in Tieling,so as to provide the basis data on preventing Esophageal cancer in Tieling.Methods The data of residents in Tieling dying of Esophageal cancer from 2007 to 2015 was collected and cleared up to calculate the evaluation indexes including the mortality rate,the average percentage change of mortality rate.GM(1,1) model was used to predict the future mortality.Results From 2007 to 2015,the Average Esophageal cancer Mortality Rate of in residents in Tieling was 5.26 per 100000 persons,and especially 1.95% raised a year.The Mortality Rate would increase from 2016 to 2019.Conclusion Tieling Esophageal Cancer mortality rate is on the rise,especially for elder men more than 60.So that the proper prevention measures should be car ried and strengthened.

Objective To examine plasma levels of protease C1 inhibitor (SERPING1) in adult patients with latent autoimmune diabetes (LADA), and their clinical significance thereof. Methods The levels of SERPING1 were detected and compared between LADA, type 1 diabetes (T1DM), type 2 diabetes (T2DM) and healthy control groups. The correlation between plasma levels of SERPING1 and other clinical indicators such as age, disease course, glycosylated hemoglobin (HbA1c), fasting blood glucose (FPG), 2 h postprandial plasma glucose (2 hPG), fasting c-peptide (FCP) and 2 h postprandi-al C peptide (2 hCP) was analyzed. Multi-factor regression analysis and receiver operating characteristic (ROC) were used to evaluate the predictive effect of SERPING1 in LADA at the early stage. Results The level of SERPING1 was significantly higher in LADA group than that of T2DM group and control group (P < 0.05). There was a negative correlation between SERPING1 and FCP, and a positive correlation between SERPING1 and HbA1c, FPG and 2 hPG (P<0.05). There were no significant correlation between SERPING1 and age, disease course and 2 hCP. FCP was analyzed by regression equation (P<0.05), and which was the main influence factor of the plasma level of SERPING1. The area under the ROC curve (AUC) of SERPING1 was 0.613 (P<0.05), 95%CI 0.514-0.712. The optimal cut-point of SERPING1 for early prediction of LADA was 289.71 mg/L, and the sensitivity and specificity were 69%and 48%respectively. Conclusion SERPING1 combined with other indicators will be useful for identifying LADA from T2DM at the early stage.

Objective To investigate the association between nonalcoholic fatty liver disease (NAFLD) and metabolism or carotid intima-media thickness (CIMT) in Type 2 diabetic(T2DM). Methods According to the liver B-ultrasonography, a total of 321 T2DM patients were divided into two groups, with or without NAFLD. Metabolic indexes such as BMI, BP, blood glucose, blood lipid, uric acid ( UA ), insulin, C-peptipe,insulin resistance index(HOMA-IR) between the two groups were compared, and the relationships between alanine aminotransferase (ALT) and the above indexes were analyzed. Furthermore,the CIMT of the two groups were compared, and the relationships between NAFLD, ALT and CIMT were investigated by correlation and regression analysis. Results Compared with the group without NAFLD, the patients with NAFLD had higher level of BMI, triglyceride ( TG ), UA, fasting blood glucose ( FBG ), fasting insulin ( FIns ), fasting C peptide (FCP) ,HOMA-IR,and lower level of high density lipoprotein ( HDL-C ) significantly; BMI ( OR = 1.25, P <0. 001 ), TG ( OR = 1.74, P = 0. 008 ) and HOMA-IR ( OR = 2. 33, P = 0.010) were independent risk factors of NAFLD while H DL-C was independent protective factor; ALT was positively correlated with BMI (r = 0. 255, P <0. 001 ) ,TG(r =0. 156,P <0. 018) ,UA(r =0. 239,P <0. 001 ) ,FIns(r =0. 213,P =0. 001) ,FCP(r =0. 199,P <0. 003), HOMA-IR ( r = 0. 247, P < 0. 001 ) and negatively correlated with HDL-C ( r = - 0. 199, P =0. 002) ,and BMI (β =0. 456,P =0. 048) ,UA (β =0. 021 ,P =0. 025) and HOMA-IR(β =3.634 ,P =0. 004)were independent associated facrors. The difference of CIMT between the two groups didn't reach statistical significance, while mutiple regression analysis revealed that ALT was independently associated with CIMT(β =0. 002,P = 0. 013). Conclusion T2DM patients with NAFLD show more serious disorder of metabolism and insulin resistance. ALT is an independent risk factor of CIMT in T2DM patients.

Objective To explore the traits of improved polyacrylamide gel electrophoresis (PAGE)-ethidium bromide(EB) staining in the detection of genotype polymorphisms.Methods The methods of PAGE-silver staining,agarose gel electrophoresis (AGE)-EB staining and improved PAGE-EB staining in polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were used to detect the μ-opioid receptor (OPRM1) A118G genotypes in case group (n =167) infants with intracranial hemorrhage (ICH),and control group(n =163) infants without ICH,to conduct a case study analysis.And the application traits of three methods were compared.Results Genotypes of OPRM1 A118G were GG (169 bp),AG (193 bp,169 bp),AA (193 bp).Both the electrophoresis methods of PAGE-silver staining and PAGE-EB could be used to detect the genotypes of OPRM1 A118G clearly in this study.There was no statistically significant difference between the resolutions of DNA fragments (P =0.884).The first method,which had 13 experiment steps,consuming 4-5 hours,involving 12 kinds of chemical reagents,and the pictures were taken with the camera,was complex,with difficult operation,more time consuming; Compared with the first method,the secondmethod was simple,which had 6 test procedures,consuming 2 hours with 8 reagents,and the pictures were taken by using an automatic gel imager.AGE-EB could not be used to detect genotypes of OPRM1 A118G.Conclusions The method of improved PAGE-EB has the advantages of fast,easy operation,and high resolution,which is worthy of wider application.
