Objective To investigate the effect of at-RA in macrophage accumulation in tubulointerstitium of rats with renal tubulointerstitial fibrosis.Methods Unilateral ureteral obstructive(UUO) rat animal models were used for the study.40 SD rats were randomly divided into 5 groups: sham group,UUO group,benazepril group,low-dose at-RA groups and high-dose at-RA groups.The rats were under intragastric administration by benazepril(10mg/(kg?d)) in benazepril group,and by(at-RA)(10mg/(kg?d)) in low-dose at-RA group and 20mg/(kg?d) in high-dose at-RA group and by sodium chloride in tales doses in sham group and UUO group from the day before the operation to 14 day after operation.Immunohistochemistry staining of CD68 and Col Ⅲ was used to define the macrophage accumulation and expression of interstitial Col Ⅲ.The degree of tubulointerstitial damage was scored by HE and Masson staining.Results Tubulointerstitial macrophage infiltration were all significantly reduced by(at-RA) or benazepril treatment.They also improved the histological changes of UUO rats and inhibited interstitial colⅢ deposition.Conclusion Reduction of interstitial macrophage infiltration may be an important event by which(at-RA) or benazepril prevents renal injury caused by UUO.

Objective To evaluate the effectiveness of MGIT liquid medium fluorescence instrument manual interpretation method for rapid detection of Mycobacterium. Methods Two hundred sputa with newly diagnosed tuberculosis patients were collected from October 2008 to January 2009 in the district hospitals in Shanghai. Of these 200 sputa, 67 sputa were positive AFB, 133 were negative. All the sputa were isolated by L-J, BacT / Alert 3D system and MGIT liquid medium methods. Results Of the 200 sputa specimens,105(52. 5% ) were isolated as Mycobacterium strains. The positive culture rate of the MGIT, BacT/Alert 3D and L-J method was 49. 5% ( 99/200 ), 48. 0% (96/200) and 45.0% ( 90/200), respectively. The MGIT culture positive rate was significantly higher than that of L-J method (x2 = 5.40, P = 0. 020 1 ). Of the 133 sputa with negative AFB, the positive culture rate was 24. 8% ( 33/133 ), 23. 3% ( 31/133 ) and 18. 8% (25/133) with MGIT, BacT/Alert 3D and L-J method, respectively. The MGIT culture positive rate with the AFB negative sputum was significantly higher than that of L-J method (x2 = 5. 33, P = 0. 020 9 ).The median time of detection with MGIT, BacT/Alert 3D system and L-J method was 11 days, 15 days and 22 days, respectively. Comparing the median time of detection of MGIT with BacT/Alert 3D, the difference was statistically significant ( Z = 3.414 ,P ＜ 0. 01 ). Comparing the median time of detection of MGIT with L-J method, the difference was statistically significant (Z =7.083,P＜0. 01).Conclusions MGIT liquid medium manual method is a rapid detection method of Mycobacterium with a high positive detection rate, and do not need expensive equipment This method may suitable to resource limited medical institutions due to its low cost and short round time.

Objective To investigate the value of human epididymis secretory protein 4 ( HE4 ) combined with CA125 assay in differential diagnosis of endometriosis cyst and ovarian malignant tumor.Methods The level of HE4 and CA125 were measured by enzyme-linked immunosorbent assay (ELISA) in the serum specimens of 46 cases in endometriosis cyst group,36 cases in malignant ovarian tumor group,60 cases in benign ovarian diseases and 50 women in healthy women group.Those results were shown with median level.The normal range were 0-150 pmol/L in HE4 and 0-35 kU/L,which either one was more than the threshold value defined as positive index.The sensitivity of assay was evaluated by receiver operating characteristic (ROC) curve,the relation and value of HE4 or CA125 alone and combination assay in diagnosis of endometriosis was analyzed by Mann-Whitney U test and correlation analysis.Results (1) HE4:the median levels of HE4 were 52.4,51.0,50.0 pmol/L in group of endometriosis,normal control and benign ovarian tumor,which didn't show statistical difference.However,HE4 was 507.5 pmol/L inovarian cancer group,which was significantly higher than those of 3 groups (P < 0.05 ).(2 ) CA125:there were significant different in median level of CA125 was observed as 743.0 kU/L in ovarian cancer,84.9 kU/L in endoemtriosis,15.4 kU/L in benign ovarian disease,and 11.5 kU/L in healthy women (P < 0.05).( 3 ) The single assay:when compared with that in endometriosis group,receiver operating characteristic area under the curve( ROC-AUC) were 0.933 in HE4 alone and 0.821 in CA125 alone assay in ovarian cancer group.The specificity was 95% and the sensitivity was 79.6% and 49.0%.(4) The combination assay:when compared with those in endometriosis group,the ROC-AUC was 0.936,the specificity was 95% and the sensitivity was 81.0% in ovarian cancer.Conclusions Measurement of HE4 could be used in differential diagnosis of endometriosis cyst.And the combination of HE4 and CA125 assay could discriminate ovarian endometriosis cysts from ovarian malignant tumors effectively.

Objective To investigate the relationship between serum homocysteine ( Hcy ) and cognitive impairment in patients with cerebral infarction combined chronic obstructive pulmonary disease (COPD) after stroke, and observe the plasma Hcy levels and cognitive function improvement when treated with folic acid and vitamin B12 .Methods 87 acute cerebral infarction combined with COPD patients as the research object, then the general clinical data were recorded, hematology indexes ( Hcy, folic acid, vitamin B12 ) were determined, and their cognitive function with a simple mental state scale (MMSE) was assayed.According to the plasma Hcy levels, the subjects were divided into Hcy-normal group (n =21) and Hcy-increased group (n=66), then compare the cognitive function between the two groups.Hcy-increased subjects were randomly divided into intervention group (conventional treatment +folic acid 2.5 mg +VitB12 0.5 mg) and control group (conventional treatment).After six months follow-up, we retested plasma Hcy levels and MMSE assessment, comparison of plasma Hcy concentration change and cognitive function improvement between two groups.Results Compared with Hcy-normal group, plasma folic acid, VitB12 levels significantly decreased in Hcy-increased group (P<0.05).And Hcy concentration was negatively correlated with folic acid(r=-0.351,P =0.000)and VitB12(r=-0.242,P=0.015)levels.In addition, the MMSE, directional force and delayed recall score decreased in Hcy-increased group compared with the Hcy-normal group ( P<0.05 ).Hcy levels were significantly lower than the baseline level (P<0.05), MMSE and the sub-project of cognitive function score increased after treated with folic acid and VitB12 for six months, although there was no statistically significant difference.Conclusion Plasma Hcy level is associated with cognitive impairment in patients with cerebral infarction combined chronic obstructive pulmonary disease (COPD), patients treated with folic acid and VitB12 may help slow the recent cognitive dysfunction after stroke in the near future.

Objective To compare the characteristics of sleep disorder and its effect on health-related quality of life in patients with Parkinson's disease (PD) between early-stage and middleand late-stages.Methods One hundred and fifty-one patients collected in our hospital from September 2014 to May 2016 were divided into PD patients at early stage (grading 1-2,n=82) and PD patients at middle-and late-stages (grading 3-5,n=69) according to Hoehn-Yahr (H-Y) grading.Mini-Mental Status Examination (MMSE),Hamilton Anxiety Rating (HAM-A) scale and Hamilton Depression Rating (HAM-D) scale,Unified Parkinson's Disease Rating Scale Ⅲ (UPDRSⅢ),H-Y grading,Non-motor Symptoms Questionnaire (NMS) and Parkinson's Disease Sleep Scale (PDSS) were used to evaluate cognition states,emotion states,movement functions,disease severity,nonmotor symptoms and sleep disturbances of patients from the two groups.The 39-item Parkinson's Disease Questionnaire (PDQ-39)was used to evaluate the quality of life of PD patients.Results The incidence of sleep disorder in PD patients at middle-and late-stages was significantly higher than that in PD patients at early stage (P＜0.05),and the total scores of PDSS in PD patients at middle-and late-stages were significantly lower than those in PD patients at early stage (P＜0.05).Fragmented sleep (31.7％ and 47.8％) and excessive sleepiness at daytime (38.7％ and 43.5％) were the most common problems in patients from the two groups.Sleep disorder was negatively correlated with duration,and scores of HAM-A,HAM-D,UPDRSⅢ and H-Y grading,while it was positively correlated with MMSE scores in patients from the two groups (P＜0.05).Sleep disorder was negatively correlated with NMS scores and daily levodopa equivalent dose in PD patients at middle-and late-stages (P＜0.05).Multivariate regression analysis indicated that PDSS total scores were negatively correlated with HAMD scores and positively correlated with MMSE scores in all patients (P＜0.05).PDSS total scores were negatively correlated with duration in PD patients at middle-and late-stages (P＜0.05).Sleep disorder was negatively correlated with total scores of PDQ39,mobility,activity of daily living,communication ability and body discomfort in PD patients at middle-and late-stages (P＜0.05).Conclusions The quality of sleep disorder in PD patients at middleand late-stages is worse than that in PD patients at early stage,and the quality of life is further reduced than that in PD patients at early stage.The course of disease has a great influence in sleep disorder of PD patients.
