Objective To understand the epidemiological characteristics of malaria in Wuxi City,and explore effective strat?egies and measures for malaria elimination. Methods The data on malaria cases in Wuxi from 2005 to 2014 were collected and analyzed. Results In Wuxi City,from 2005 to 2014,201 malaria cases were reported,of which,there were 52 local cases and 149 imported cases. Totally 156 malaria cases were reported from 2005 to 2009,of which 6 cases were infected with Plasmodi?um falciparum,and 45 malaria cases were reported from 2010 to 2014,of which 23 cases were infected with P. falciparum. From 2005 to 2009,the ratio of male to female was 2.39:1. Migrant workers,farmers and workers were the major infected popu?lations,with a proportion of 41.03%,17.95% and 9.62%,respectively. From 2010 to 2014,the ratio of male to female was 10.25:1. Workers,farmers and migrant workers were the major infected populations,with a proportion of 37.78%,11.11%and 6.67%,respectively. The peak of malaria incidence was observed from May to October. From 2005 to 2009,most cases were re?ported by CDCs,and from 2010 to 2014,most cases were reported by medical institution. There was an increase in proportion of P. falciparum. Conclusion The control and prevention of malaria should focus on imported cases in the future in Wuxi. The doctors should improve the capacity of malaria diagnosis and treatment.

Manganese(Mn) is one of the essential trace elements in biologic metabolism.With proper quantity,Mn acts as some enzymes’active groups,reactivators,and participates in the physiological functions of central nervous system.Overdose exposure to Mn in industry may result in occurrence of occupational manganism,which can cause damage of many aspects of the body such as nerve,immunity and reproduction.The aim of present essay is to review the current studies on nerval behavior function and biomarkers of manganism both in China and other countries.

0.05).The third day after SE,the expressions of MVP in CA1 and CA3 in adult rats experiment group increased,and in CA3,the value reached up to(4.0?1.41)in adult experiment group,which had significant differences compared with control groups(P

Objective To study the effects of He-Ne laser irradiation on histological changes and the expression of proliferating cell nuclear antigen ( PCNA ) and B-cell lymphoma/leukemia-2 ( Bcl-2 ) in the gastric mucosa of rats with chronic atrophic gastritis (CAG) so as to elucidate the relationship of He-Ne laser irradiation with precancerous lesions and apoptosis in the gastric mucosa. Methods The rats were divided into a normal group,a model group and a laser group.A model of CAG was established by gastric perfusion with a mixture of sodium salicylate and alcohol combined with irregular fasting and forced exercise.A He-Ne laser was used to irradiate the rats at 3.36 J/cm2 for 7 min daily for 20 d.Histopathological changes including the severity of inflammation in the gastric mucosa and the morphology and structure of the parietal cells were observed with a light microscope,and the expression of PCNA and Bcl-2 was detected with immunohistochemical methods. Results The pathologic morphological changes in the gastric mucosa of the model group were atrophy of the glands of the gastric mucosa and notable inflammatory infiltration.But in the laser group inflamed cells decreased,and the morphology,structure and volume of the cells all recovered close to normal.The immunohistochemistry results showed that during the atrophy of the gastric mucosa the expression of PCNA and Bcl-2 was elevated,and it was significantly higher in the model group than in the normal group.After irradiation the expression of PCNA and Bcl-2 was significantly lower. Conclusions There was hyper-proliferation in the gastric mucosa of the CAG model rats,with high expression of apoptosis suppressor PCNA and Bcl-2 proteins.Laser irradiation can reduce the expression of PCNA and Bcl-2,enhance cell proliferation and induce apoptosis,preventing the development of cancer.Laser irradiation has a good adjuvant therapeutic effect for all the pathological changes observed.

Objective To investigate the pancreas size and echo characteristics of patients with glucose metabolism disorders including type 2 diabetes,and to study its related factors.Methods One hundred and fifty-seven patients from Nanjing Drum Tower Hospital with normal glucose metabolism,impaired glucose regulation,newly diagnosed type 2 diabetes and established type 2 diabetes were collected.The average gray scale intensity of the liver,kidney,pancreas region of interest was measured by using the histogram method.Then the liver and kidney echo ratio,liver attenuation coefficient was calculated,and the fat content of liver was determined by using formula.The size of pancreas head,body and tail was detected by ultrasound,and the sum of three values was used as the pancreas size indicator.Univariate and multivariate logistic regression analysis was performed on the size of pancreas and intensity of echo.Results The size of pancreas ranged from 2.39 ～ 6.09 cm with a mean size of (4.43 ± 0.59) cm,and the size was ≤ 5 cm in 130patients,＞5 cmin 27 patients.The intensity of echo ranged from 41.0 ～ 190.6 with a mean number of 120.0 ±31.1,and the intensity of echo was ≤120 in 83 patients,＞ 120 in 74 patients.The content of liver fat ranged from-1.11％ ～ 62.50％ with a mean number of (15.67± 11.97)％.Univariate logistic regression analysis suggested the size of pancreas was related to age and obesity,and pancreas echo was related to obesity degree,types of participants,the level of blood glucose,and grade of fatty liver (all P ＜ 0.05).Multivariate logistic regression analysis indicated obesity degree is the most important factor for prediction of pancreas size and echo (P ＜ 0.05).Conclusions Quantitative ultrasound measurement of pancreas size and echo can reflect the degree of fat infiltration of pancreas,and it has some clinical value.

Breast cancer is a multistep process with abnormalities of some biomarkers.Knowledge of biomarkers can provide prognostic information in addition to the clinicopathologic factors,and is useful to carry out the indiviual treat- ment.In this review,we summarized the most recent work in the field of biological markers used for the prognosis,such as Her-2/neu,P53,BRCA1,Angiogenesis,LOH,et al

Tamoxifen and letrozole are two of the most effective pharmaceuticals mainly used in hormonal dependent) breast cancer therapy. A trace analytical method using ultra performance liquid chromatography/tandem mass spectrometry(UPLC-MS/MS) was developed to simultaneously detect these two drugs in both influent) and effluent of municipal sewage treatment plant. Sewage samples were passed through an Oasis HLB cartridge, then an amino solid phase extraction cartridge was connected with Oasis HLB cartridge. Target compounds) was firstly eluted with 6 mL methanol and then 3 mL methanol was used to elute the amino solid phase extraction cartridge, collected and pooled the elutants. After concentration, target compounds were separated) on a BEH C_(18)) column using a gradient elution profile with a mobile phase consisting of 0.1% formic acid aqueous) solution and acetonitrile and detected by an electro spray ionization tandem mass spectrometry with multiple reactions monitoring(MRM). Satisfactory linearity(R~2>0.997) was obtained over the range of 1.0-100 μg/L) and 0.1-100 μg/L for tamoxifen and letrozole, respectively, with limits of quantification(LOQ) of 1.0 and 0.1 ng/L. Mean recoveries of two target compounds(spiked in sewage samples at three concentration levels) ranged from 68.8% to 103.0%, with relative standard deviations(RSD) less than 15%. This method can be applied for the analysis of target drugs sewage samples.
