Objective To analyze the correlation between non-motor symptoms (NMS) and the quality of life in the mild Parkinson's disease (PD) patients of different genders.Methods 85 mild PD patients (H-Y stage 1～2) were investigated.The PD NMS Quest was used to assess NMS.The quality of life was assessed with SF-36 questionnaire.Results Stepwise linear regression analysis showed that nocturia,restless legs,depression,daytime sleepiness,decreased interest,smell taste problems were positively correlated with the score of life quality of male and pain,increased sweating,taste smell problems,sleep problems,changes in libido,decreased memory,diplopia influenced life quality score of female.The scores of SF-36 questionnaire of the male with PD were lower than that of female patients.Conclusions The nonmotor symptom (NMS) There was a gender difference about the influence that NMS has made on PD patients.The male's life quality were lower than that of female patients about mild PD patients.

Objective To evaluate the values of combined detection of soluble mesothelin related proteins (SMRP)and carbohydrate antigen 1 25 (CA1 25)in the diagnosis of malignant peritoneal mesothelioma.Methods 20 patients with malignant peritoneal mesothelioma were selected as the malignant group,50 patients with benign ovar-ian tumor were selected as the benign group,60 healthy women were selected as the control group.Enzyme -linked immunosorbent assay(ELISA)was adopted to detect serum SMRP levels and electrochemiluminescence immunifaction (ECLI)was adopted to detect serum CA1 25 levels.The SMRP,CA1 25 levels were compared among all groups,the sensitivity,specificity of SMRP and CA1 25 in the diagnosis of peritoneal malignant mesothelioma were analyzed. Results Serum levels of SMRP,CA1 25 in malignant group were (1 4.8 ±1 .6 )μg/L,(1 89.1 ±1 5.3 )μg/Lrespectively,which were significantly higher than those in the benign group[(3.9 ±0.9)μg/L,(28.6 ±4.2)μg/L] (t =27.40,49.61 0,all P <0.01 )and the control group[(2.8 ±0.7)μg/L,(1 6.9 ±3.8)μg/L](t =29.877, 53.334,all P <0.01 ).The sensitivities of SMRP,CA1 25 detection alone for malignant peritoneal mesothelioma diag-nosis were 65.0%,50%,respectively,while their specificities were 83.6%,79.1 %.The sensitivity and specificity of combined detection of SMRP and CA1 25 for malignant peritoneal mesothelioma were 95.0% and 93.6%.Conclusion SMRP has some value in the diagnosis of peritoneal malignant mesothelioma.SMRP combined with CA1 25 detection can markedly improve the diagnostic sensitivity and specificity for malignant peritoneal mesothelioma.

Objective To investigate the relevant mechanism of different concentrations of Shenqi YiliuDecoction medicated serum on blocking cell cycle and inhibiting invasion and metastasis of gastric cancer cell lines MKN-45. Methods Sixty SPF Wistar rats were randomized intoShenqi Yiliu Decoction low-, medium-, and high-dose groups and control group, with 15 rats in each group. Low-, medium- and high-dose groups were fed with different concentrations of TCM liquid from which containing crude medicine (0.25, 0.50, 1.00 g/mL) separately for gavage. Rats in the blank group were given the same amount of drinking water for gavage, twice a day, for 7 days.2 h after the last gavage, rat blood was taken and serum was separated. After MKN-45 cells were dealt with different concentrations of medicinal serum, FCM was used to detect cell cycle and immunohistochemistry technology was used to detect the expressions of COX-2 and PTEM proteins.Results FCM analysis showed that medicated serum could increase G0-G1 phase and shorten S phase of cells; medicated serum could reduce the positive expression rate of COX-2 of the MKN-45 cells and increase positive expression rate of PTEN proteins (P<0.05).ConclusionShenqi YiliuDecoction medicated serum can block the cell cycle and inhibit invasion and metastasis of MKN-45 cell lines, which may be related to the intervention in the expression levels of COX-2 and PTEN proteins.

Immunohistochemistry was carried out for assessment of the expression of IgG4 and IgG in 29 patients with Hashimoto's thyroiditis (HT) and 26 other patients with subacute thyroiditis,thyroid adenoma,and thyroid carcinoma.HT group were divided into IgG4 HT (10/29) and non-IgG4 HT (19/29) groups.Statistical analyses of clinical and histological characteristics were also conducted in both groups.2 cases of subacute thyroiditis were IgG4 positive (2/26).The IgG4 positive plasma cells,IgG positive plasma cells,and ratio of IgG4 +/IgG + plasma cells in IgG4 HT cases were significantly higher than non-IgG4 HT ones(P＜0.05).The serum Fl4 in IgG4 HT cases were lower than non-IgG4 HT ones(P＜0.05).After operation,IgG4 HT had a greater proportion for accepting thyroxin treatment(P＜0.05).IgG4 HT is a new-found disease which has particular histological and immunological features and would have good response for cortical hormone therapy.Serum and tissue examination of IgG4 seems to be helpful to the diagnosis of IgG4 HT.

A method for simultaneous determination of 25 kinds of fungicides in cereals, vegetables and fruits using SPE-LC-Q-TOF/MS technique was developed.The samples were extracted with acetonitrile containing 1% (V/V) acetic acid, purified by solid phase extraction (SPE) with a Crabon/NH2 cartridge, eluted with acetonitrile-toluene(3∶1, V/V), separated by a reversed phase C18 column, gradiently eluted with acetonitrile and 0.1% formic acid solution (Containing 5 mmol/L ammonium acetate), determined by LC-Q-TOF/MS, and quantified by external standard method.A data base of the accurate mass numbers and a library which contains 25 kinds of fungicides were established.The automatic retrieval of detection results was carried on according to the characteristics of the compound, such as accurate mass, retention time, isotope peak distribution, isotopic ratios, and so on.Based on the above results, the qualitative identifications of the 25 new fungicides were accomplished without the contrast of standard substances.The results indicated that 25 fungicides showed good linearity in the range of 0.02-200 μg/L, and the limits of detection (LOD) and the limits of quantification (LOQ) were 0.01-5.00 μg/kg and 0.02-20.00 μg/kg, respectively.The linear relative coefficients were greater than 0.995.The recoveries were in the range 71.8%-114.0% and the relative standard deviations (RSD) were ranged from 0.1% to 21.3% (n=3).The method has some advantages such as simplicity, rapidity and high sensitivity, and is suitable for the rapid determination of the common fungicides in cereals, vegetables and fruits.
