Spatial statistics plays an important role in spatial epidemiology studies of echinococcosis .Spatial statistics can be used to describe the spatial distribution ,predict the prevalence ,identify disease clusters ,and analyze the influencing factors of echinococcosis .To describe spatial distribution and predict the prevalence ,we can use spatial interpolation ,empirical bayes smoothing and ellipsoidal gradient .Spatial autocorrelation always used to identify disease clusters .Moran's I value ,Getis'G val‐ue and spatial scan statistics are used to judge spatial autocorrelation .Molding plays an important role on analyzing risk factors of echinococcosis .Generalised linear mixed models and Bayesian model are always performed with both spatial factors ,such as geomorphologic features ,climatic characteristics ,vegetation index and factors which make great effect on disease transmission . To figure out the spatial distribution of echinococcosis is significant for echinococcosis control and prevention .

To evaluate the inhibitory effects of fas gene transduction on oesophageal cancer cells in vitro, the eukaryotic expression vector fas pBK was constructed and transfected into oesophageal carcinoma cells EC109. Western blot results showed high expression of Fas protein in gene transfected cells Fas EC109. Cell growth curve and plating efficiency test revealed that Fas EC109 had longer population doubling time and lower plating efficiency compared with control cells. Results of MTT assay showed increased sensitivity of Fas EC109 cells to CDDP, VCR and 5 FU. All these data suggested that transgenic expression of fas gene could effectively inhibit the proliferation and increase the drug sensitivity of oesophageal carcinoma cells in vitro.

Objective To investigate the mechanism of high phosphate - stimulated calcification in vascular smooth muscle cell. Methods The cell culture of bovine aortic smooth muscle was performed. Osteocalcin (OC) mRNA expression and calcium deposition in different phosphate concentrations [normal phosphate (Pi 1. 5mmol/L), high phosphate (2.0mmol/L)] were determined by radioimmunoassay, RT-PCR, and 0-cresolphthalein complexone method respectively. Results After 72 hours,high phosphate treatment of smooth muscle cells(SMC) enhanced the expression of osteocalcin protein [Pi 2. 0 mmol/L versus Pi 1. 5 mmol/L: (15. 03?2. 60) pg/u-g protein versus (2. 98 ?0.84) pg/ug protein, P

Objective To ascertain the causes of priapism and to differentiate between the ischemic low-flow type and nonischemic high-flow type so as to improve the clinicians' ability for emergency treatment of priapism. Methods Ten cases of priapism were included.Their mean age was 41 years (range,22～64 years).The priapism lasted 8 to 212 h with a mean of 21.2 h.Of them 1 case had received prostaglandin E,papaverine and phentolamine injection into cavernous body of penis,which led to ED;1 had priapism when experiencing sexual intercourse after taking sildenafil;1 had primary sarcoma of the penis;1 had transitional cell carcinoma of bladder, which metastasized to the penis;1 had leukemia; 2 had traumatic history;and 3 had unknown causes.The types,causes,treatment and outcomes of priapism were analyzed. Results Of the 10 cases,8 were of ischemic low-flow type and 2 of nonischemic high-flow type. In the 8 cases of ischemic low-flow type priapism, 4 achieved detumescence after receiving metaraminol injection (2～8 mg) at the root of cavernous body,and perfusion of haparinized saline at glans and root of cavernous body of the penis by contrecoup if necessary (1 had ED).One case undergoing glandular-cavernosal shunting achieved detumescence with preservation of erectile function.One case with leukemia was cured after chemotherapy.One case suffered from penile sarcoma and the rest 1 from metastasis of transitional cell carcinoma; the prognoses of both were unfavorable.Of the 2 cases of high-flow type,1 achieved detumescence after selective embolization of internal pudendal artery;the other was discharged after conservative treatment,but experienced ED. Conclusions Blood gas analysis of cavernosal blood,color Doppler ultrasound,and internal pudendal arteriography are useful in differentiating the types of priapism.If conservative treatment fails to achieve detumescence of the penis,surgical treatment should be performed immediately for both types of priapism.

Objective To investigate the expression of indoleamine 2,3-dioxygenase(IDO)in renal tissues of crescent nephritis and its correlation with cell proliferation and pathologic tubulointerstitial lesion.Methods Immunohistochemistry was used to detect IDO expression in renal tissues of crescent nephritis and normal renal tissues.The correlation between IDO expression and the number of proliferating cell nuclear antigen(PCNA)positive cells or pathologic tubulointerstitial lesion were analyzed.Results IDO expression was found in the renal tubular epithelial cells of crescent nephritis,while that in the normal renal tissues was negative by immunohistochemical staining.The expression of IDO protein in tubular epithelial cells showed a significantly negative correlation with the number of PCNA positive cells or tubulointerstitial lesion of crescent nephritis.Conclusion IDO may participate in the pathogenesis of crescent nephritis by inhibiting the cell proliferation.

Objective To explore and analyze the risk factors affecting psychological status of adolescent orthodontic patients in stomatology department, and to develop intervention strategies according to the results. Methods A total of 186 cases of adolescent orthodontic patients in stomatology department from September 2012 to September 2015 were selected, and psychological status was investigated by Chinese Middle School Students Mental Health Scale (MMHI-60 scale) and Symptom Self-rating Scale (SCL-90).The patients were divided into observation group (with psychological problems) and control group (without psychological problems) according to the psychological status scale scores. Univariate descriptive analysis and multivariate Logistic regression analysis were used to determine related factors of the possible influencing factors, and the intervention strategies were developed. Results The factors such as social roles, living area, single parent, only child, internal and external tropism, neuroticism, being given health education, malocclusion severities of the deformities were closely related to psychological status of adolescent orthodontic patients in stomatology department (χ2=2.534-44.297, P<0.05 or 0.01). The independent risk factors were classified as high to low according to the degrees of danger: severe malocclusion (OR=3.578, P=0.000), instability emotional (OR=2.934,P=0.000), workers (OR=1.857, P=0.011) and rural life (OR=1.632, P=0.014), while the factors such as outgoing personality (OR=0.628, P=0.008) and being given health education (OR=0.746, P=0.010) were protective factors. Conclusions The factors such as severe malocclusion, instability emotional, workers,rural life,outgoing personality and health education are the related risk factors affecting psychological status of adolescent orthodontic patients in stomatology department, and psychological health intervention should be strengthened in the clinical practice to improve the psychological status and compliance.

Tumor-associated macrophages (TAMs) exist in the tumor microenvironment,and can be affected by various anticancer treatments and further affect tumor progression.Increasing evidence suggests that many of the clinical antitumor measures can play a unique and effective antitumor effect by regulating the recruitment,polarization and related pro-tumor behavior of macrophages in the tumor microenvironment.Now,tumor microenvironment immune remodeling has become a hot spot in the research of anti-tumor therapy.This paper reviews the related research progress on antitumor effects of TAMs as an therapeutic target.

By analyzing the mechanism of pronunciation, traditional acoustic parameters, including fundamental frequency, Mel frequency cepstral coefficients (MFCC), linear prediction cepstrum coefficient (LPCC), frequency perturbation, amplitude perturbation, and nonlinear characteristic parameters, including entropy (sample entropy, fuzzy entropy, multi-scale entropy), box-counting dimension, intercept and Hurst, are extracted as feature vectors for identification of pathological voice. Seventy-eight normal voice samples and 73 pathological voice samples for /a/, and 78 normal samples and 80 pathological samples for /i/ are recognized based on support vector machine (SVM). The results showed that compared with traditional acoustic parameters, nonlinear characteristic parameters could be well used to distinguish between healthy and pathological voices, and the recognition rates for /a/ were all higher than those for /i/ except for multi-scale entropy. That is why the /a/ sound data is used widely in related research at home and abroad for obtaining better identification of pathological voices. Adopting multi-scale entropy for /i/ could obtain higher recognition rate than /a/ between healthy and pathological samples, which may provide some useful inspiration for evaluating vocal compensatory function.
