The medical insurance is provided by the Unified Health System (SUS) covering most of Brazilians and alsocombined with private insurance, and every Brazilan could get access to basic health services. The major diseaseas leading to death in Brazil are ischemic heart disease, stroke and lower respiratory infection. The incidence of AD, chronic kidney disease and diabetes are increasing in recent years. Traditional Chinese Medicine (TCM), which was represented by acupuncture, was introduced to Brazil in the early 19th. At present, acupuncture has been widely accepted and used, which was included in SUS. A number of universities have acupuncture courses. However, the specialities and advantages of TCM needs to be strengthened, the local practioners lack the understanding of TCM theory, the appropriate use of herbal medicine, and there lacks TCM education standards, all these limit the development of TCM. Thus, in order to promote the development and dissemination of TCM in Brazil, it is suggested to give full play of the characteristics of TCM in preventing disease, increase the research and development input of herbal medicine, standardize the education stystem of TCM, etc.

Objective: To understand the characteristics relating to the etiology and complications of hand, foot and mouth disease (HFMD) based on data from the pilot National Sentinel Surveillance (NSS) program so as to explore the feasibility, advantages and disadvantages of the NSS. Methods: Data were extracted from the NSS system, conducted in 11 provinces of China from November 2015 to October 2016. Characteristics regarding the etiology, complications of HFMD and factors related to the positive rates of HFMD specimens were analyzed under the logistic regression method by SPSS 20.0 software. Results: A total of 4 783 specimens were collected, including 3 390 from mild, 1 390 from severe and 3 from death cases. The overall positive rate was 81.43% (3 895/4 783). Other enteroviruses (non EV71/Cox A16 enteroviruses) appeared the major serotype (52.68%, 1 482/2 813) for mild infection of the disease while EV71 was for the severe cases (65.31%, 706/1 081). The serotype spectrum revealed by the pilot NSS was almost identical with the existing surveillance system. Other enteroviruses tended to infect younger children (χ²=130.17, P<0.001) than EV71 and Cox A16, in China. The multivariate logistic regression results showed that higher positive rate was associated with specimens which were collected from males, at children’ hospitals, in peak seasons, timely and in stools. The positive rates presented downwarding trends with the extension of the onset-sampling interval (χ²=14.47, P<0.001 in stool specimen; χ²=31.99, P<0.001 in throat swab; χ²=24.26, P<0.001 in anal swab). Aseptic meningitis, non-brainstem encephalitis and brainstem encephalitis appeared the top three complications of both EV71-associated and other enteroviruses-associated severe HFMD cases. Conclusions Factors as gender, season/place/timeliness of specimen collection, and types of hospital all appeared independently influenced the positive rates. NSS seemed feasible to be used as an alternative or supplement tool to the existing surveillance program in China.

Objective To explore the feasibility of bioelectrical impedance analysis in assessing resting energy metabolism(REM)and the association of REM with anthropometry in hemodialysis patients.Methods Adult hemodialysis patients from 11 hemodialysis facilities in Guizhou Province were enrolled in this study.Bioelectrical impedance analysis was used to measure the rest metabolic rate(RMR)and body composition of 765 patients undergoing regular dialysis.A standard method was used to measure their height,weight,upper arm circumference,triceps skinfold thickness,left calf circumference and grip strength.The upper arm muscle circumference was also calculated.The level of RMR and body composition in hemodialysis patients were compared by gender grouping.The patients were then divided into four groups according to the RMR quartile.Spearman correlation analysis and multiple linear regression analysis were derived to analyze the relationship between RMR and anthropometry.Results The level of RMR in male patients was significantly higher than that in female patients[1591(1444,1764)Rcal/d and 1226(1104,1354)Rcal/d,P ＜ 0.001].Compared with the first quartile of RMR group,upper arm circumference,upper arm muscle circumference,left calf circumference and grip strength in the fourth quartile group were increased significantly(all P ＜ 0.05).Multiple linear regression analysis showed that height(β=0.572),left calf circumference(β=0.273),upper ann muscle circumference(β=0.092)and suffering from protein energy wasting(PEW,β=-0.184)were independent influential factors of RMR(all P ＜ 0.05).Conclusions RMR levels in patients with maintenance hemodialysis are associated with left calf circumference and upper ann muscle circumference,which may become a new index to evaluate energy consumption and malnutrition in MHD patients.

Objective To investigate the expression of connective tissue growth factor (CTGF) and heat shock protein 47 (HSP47) in peritoneum fibrosis rats,and the mechanism of 1,25-dihydroxyvitamin D3 [1,25-(OH)2-VitD3] in inhibiting the peritoneum fibrosis.Methods Adult male Sprague-Dawley rats were randomly divided into 3 groups:control group (n=8),model group (n=8) and 1,25-dihydroxyvitamin D3 group (VitD3,n=8).The model of peritoneum fibrosis rats were induced by daily intraperitoneally injection of 15％ chlorhexidine gluconate (CHX) 0.2 ml/d with 0.1％ glucose for 4 weeks.Rats in VitD3 group were also treated with 1,25-(OH)2-VitD3 [i.p.6 ng· (100 g) 1 · d-1].Peritoneal transport function,renal function,peritoneum thickness and serum level of 25hydroxyvitamin D3 were detected.In vitro,primary cultured peritoneal mesothelial cells were divided into control group,high glucose group (HG,2.5％),CTGF siRNA intervention group (CTGF siRNA+HG),VitD3 intervention group (VitD3+HG) and combined intervention group (CTGF siRNA+VitD3+HG).Real-time PCR,Western blotting and immunofluorescence were applied to measure the expression of CTGF and HSP47,also ELISA was used to detect the protein level of FN in peritoneum and peritoneal mesothelial cells.Results Compared with control group,the peritoneal ultrafiltration in peritoneum fibrosis rats were significantly decreased (P ＜ 0.05),the absorbance level of peritoneal fibrosis,peritoneum thickness,the rate of dialysate urea nitrogen and blood urea nitrogen (DUN/BUN) and the expressions of CTGF and HSP47 were increased (all P＜0.05).After application of 1,25-dihydroxyvitamin D3,peritoneal fibrosis lesion was significantly improved,the peritoneum thickness,the expressions of CTGF and HSP47 were decreased (all P ＜ 0.05).In vitro,2.5％ high glucose induced-peritoneal mesothelial cells were respectively treated by CTGF siRNA,1,25-(OH)2-VitD3 and combined interventions,the expression of FN,CTGF and HSP47 was significantly lower than that in high glucose group (all P ＜ 0.05).Conclusions The expression of CTGF and HSP47 is significantly increased in peritoneal fibrosis rats.1,25-(OH)2-VitD3 may ameliorate the progression of peritoneal fibrosis via reducing the expression of CTGF,decreasing the expression of HSP47 and FN.

Objective To apply 3D printing technology to fabricate patient-specific silicone tissue compensators for the chest wall and compare the advantages and clinical characteristics between conventional bolus and 3D-printed PLA materials. Methods The chest wall data of two breast cancer patients undergoing mastectomy were obtained based upon the CT images. A patient-specific 3D printing silicone rubber bolus (3D-SRB) was designed and fabricated. The conformability of 3D-SRB,3D-PLA and conventional bolus to the chest wall were validated. Ecipse8. 6 planning system was adopted to statistically compare the dosimetric parameters of virtual plan with those after using three tissue compensators. Results The 3D-SRB was successfully designed and fabricated with a similar hardness to conventional bolus. During the process of validating conformability and radiotherapy planning,3D-SRB and 3D-PLA were superior to conventional bolus in terms of conformability to chest wall and planning dosimetric distribution.3D-SRB was advantageous in repeatability, conformability and comfortable experience compared with 3D-PLA. Regarding dosimetric parameters,3D-SRB yielded the highest repeatability with the virtual plan, followed by 3D-PLA and conventional bolus. Conclusion It is applicable to utilize 3D-SRB as the patient-specific compensators for the chest wall,which is of significance in clinical practice.

Background and purpose:Pathogenic gene polymorphism may affect the function of gene, leading to the difference of individual tumor susceptibility and heterogeneity of bioactive substances in individuals. The purpose of this study was to investigate the interrelationship betweenHER-2 gene polymorphism and its protein expression, and to evaluate their association with the clinicopathological characteristics of breast cancer.Methods:The data from a total number of 303 female breast cancer patients of Han ethnicity were collected. The MassARRAY platform was used to examineHER-2 gene rs2517954 and rs2517955 single nucleotide polymorphisms. Meanwhile immunohistochemistry was used to detect HER-2 protein expression and corresponding estrogen receptor (ER), progesterone receptor (PR), P53 and Ki-67 expressions in breast cancer tissues. Pearson chi-square test was used to study the relationship of the two loci and the protein expression, and their correlation with clinicopathological features of breast cancer was analyzed.Results:Under the codominant model,HER-2 gene rs2517954 and rs2517955 loci polymorphisms were associated with its protein expression (χ2=9.613,P=0.008;χ2=9.613,P=0.008). And under the dominant model,HER-2 gene rs2517955 loci TT homozygous and CT heterozygous mutant was associated with its protein expression (χ2=8.894,P=0.003). There were no signiifcant correlations betweenHER-2 gene rs2517954, and rs2517955 loci polymorphisms, and breast cancer patients’ clinical stage, tumor size, histological grade, lymph node metastasis, ER, PR, Ki-67 and P53 expressions (P>0.05).Conclusion:HER-2 gene rs2517955 loci polymorphism is correlated with its protein expression. Further studies may be helpful to elucidate the mechanism of HER-2 protein expression in breast cancer.
