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.

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 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.

Background and purpose:The expression of ERβin triple negative breast cancer(TNBC) might be associated with good prognosis in TNBC patients. ERβand ERαhave considerable homology. FOXA1 plays an important role in ERαexpression and function. The aim of this study was to analyze the expression of FOXA1 and ERβin TNBC and the relationship between them and the clinicopathologic characteristics and prognosis. Methods:The breast cancer samples in Peking Union Medical College Hospital were collected from Nov. in 2011 to Dec. in 2013, and TNBC were screened out based on the expression of ERα, PR and HER-2. Thirty ERβ-negative samples and 30 ERβ-positive samples were selected randomly according to the ERβexpression. We used immunohistochemical method to detect the expression of FOXA1. Finally, 48 TNBC samples were obtained to analyze the results. Results:The total positive rate of FOXA1 was 35.4%(17/48). In the ERβ-positive group, the positive rate of FOXA1 was 35.7%(10/28),and in the ERβ-negative group, the positive rate of FOXA1 was 35% (7/20). The expression of FOXA1 in these 2 groups had no signiifcant difference (P=0.83), which indicated that there was no relation between ERβand FOXA1. The FOXA1 positive group and FOXA1 negative group also showed no signiifcant difference in age, tumor size, and lymphatic metastasis number in axilla, tumor grade, tumor stage, NPI and DFS. However, Ki-67 showed negative correlation with FOXA1 expression (P<0.01). Conclusion:FOXA1 expression had no relationship with ERβexpression in TNBC. Ki-67 showed negative correlation with FOXA1 expression, which might hint that the proliferation of tumor cell was lower in FOXA1 positive TNBC.

BACKGROUND: Scholars disagree with each other about the small saphenous vein effects on skin flap and how to dispose vascular proximal pedicles.OBJECTIVE: To analyze effects of different methods of the small saphenous vein disposal on flap survival using sural neurocutaneous island flap retrograde metastasis for repairing defects of soft tissue of instep, heelstick and ankle.DESIGN, TIME AND SETTING: The case control observation experiment was performed at the General Hospital of Guangzhou Military Area Command of Chinese PLA from March 1998 to April 2007.PARTICIPANTS: A total of 56 patients with defects of soft tissue of instep, heelstick and ankle were divided into 2 groups,small sapbenous vein deligation in proximal pedicle flap group (group A) (n=38), and proximal small saphenous vein and great saphenous vein or tributaries at recipient site anastomosis flap group (group B) (n=18).METHODS: During sural neurocutaneous island flap retrograde metastasis for repair,(3.5×4.0)cm-(4.0×4.5) cm flap was obtained in 35 cases, and (4.0×4.5) cm -(10.0×12.0) cm in 21 cases.MAIN OUTCOME MEASURES: Outcome of flap survival at different incision area and implanted methods.RESULTS: No vein articulo occurred in 21 cases, which flap areas were (4.0×4.5) cm -(10.0×12.0) cm. Five of 35 cases which flap areas were (3.5×4.0) cm -(4.0×4.5) cm developed vein articulo.The necrotic rate of flaps in group B was significantly lower compared to the group A (P=0.017 67).CONCLUSION: When the area of skin flap is smaller than (4.0×4.5) cm, the proximal end of the small saphenous vein should be anastomosed with the great saphenous vein or tributaries connecting with the great saphenous vein at recipient site.The small saphenous vein is not a superficial vein, which only cross the skin flap, but it has trophic action on the skin flap.
