Objective To know the state of endemic fluorosis,running state of water improvement project in Jiangsu Province,and to provide a scientific basis for adjusting control measures against the disease.Methods Nine key counties were selected from the endemic fluorosis areas as survey spots in Jiangsu in 2012.Three villages in each spot were selected as survey villages.To known the progress and running conditions of water facilities,water samples were collected to determine the fluorosis level.All children aged 8 to 12 were tested for dental fluorosis at the survey villages.The fluorine content in water was determined with F-selective electrode (WS/T 106-1999).Dental fluorosis was diagnosed byased on the Dean method.Results Twenty-seven villages were investigated,the number of villages that had water quality improved was 26,the rate was 96.30％ (26/27);the number of villages that did not have water quality improved was 1,the rate was 3.70％ (1/27).Among the 26 facilities,21 improved-water facilities ran normally,the rate was 80.77％ (21/26);2 facilities ran with intermittently water supply,the rate was 8.70％ (2/26);3 facilities were scraped,the rate was 11.54％ (3/26).In the villages with normal improved-water facilities and qualified water fluorosis,the total rate of dental fluorosis of children aged 8 to 12 was 22.74％ (380/1 761),the index of dental fluorosis was 0.45.In the villages with abnormal improved-water facilities and excessive water fluorosis,the total rate of dental fluorosis of children aged 8 to 12 was 66.51％ (143/215),the index of dental fluorosis was 1.45.The total rate of dental fluorosis of children aged 8 to 12 was 42.86％ (12/28) in the villages which had not changed water source,the index of dental fluorosis was 0.86.Conclusion Improvement of water decreasing fluorine project in Jiangsu Province has a certain effect on children's dental fluorosis,but some of the water fluorosis projects are scrapped,and excess fluorine water should be taken seriously.

Objective To discuss the clinical value of immunofecal occult blood test in screening of colorectal cancer and its precancerous lesions in a large series of health checkup population. Methods Colorectal cancer and its precancerous lesions in 5919 subjects undergoing health checkup in our hospital were screened out by using immunofecal occult blood test from July 2006 to June 2007; positive cases with the test were subjected to colorectal endoscopy or X-ray barium enema examination. Relevant results were analyzed in combination with clinical and pathological data. Results Positive result was obtained in 314 out of the 5919 subjects undergoing health checkup with immunofecal occult blood test; the positive rate was 5.30%. 241 cases(76.75% )of them accepted colorectal endoscopic examination and 23 cases(7.32%) accepted X-ray barium enema examination. The total follow up rate was 84.08% with 50 cases out of contact. After excluding the cases out of cantact, 16 cases of colorectal cancer were found morbidity 2.37‰ including 8(50.00% )cases of Dukes A,7 cases (43.75%)of Dukes B and 1 case of Dukes C (6 .25%).The detection rate of colorectal cancer with postive imunofecal occult blood test was 6.06% (16/264). 94 cases (16.01‰) of adenomatous polyps were found including 55 cases (58.51%) of tubular adenoma, 23 cases (24.47% )of villiform- tubular adenoma and 16 cases(17.02%) of villfform adenoma. Among these cases 55 (58.51%)were solitary and 39(41.49%) multiple. In addition, 6 cases of ulcerative colitis in active phase were found. Altogether 116 (43.94%)of the 264 cases with positive immunofecal blood test and not out of contact were found to have colorectal cancer or its precancerous lesions. Conclusion Immunofecal occult blood test is suitable for screening of colorectal cancer and its precancerous lesions in large series of population. Colorectal cancer and its precancerous lesions may be found in relatively early phase and be eradicated in curable stage, thus to reduce the morbidity and mortality.

ObjectiveTo investigate the correlation between any two of Capsule Endoscopy ScroringIndex (Lewis score),simplified Crohn Disease Activity Index (CDAI) and C-reactive protein (CRP) in small bowel Crohn disease (CD).MethodsA total of 58 consecutive patients with known small bowel CD were enrolled. We evaluated disease activity with Lewis score and simplified CDAI. Correlations among CRP,simplified CDAI and Lewis score were calculated with Spearman's rank order correlation coefficient.The optimal CRP cut-off value was calculated using the ROC curve.ResultsThe Lewis score showed inactive,mild and moderate-severe patients were 13,21 and 24,respectively.CRP of moderate-severe group was significantly higher than that in mild and inactive groups ( P ＜ 0.05 ).The optimal CRP cut-off value that differentiated patients with moderate to severe disease from the others was 13.50 mg/L with sensitivity of 87.5％ and specificity of 82.4％.The area under the ROC curve to analyze the cut-off was 0.849.Lewis score was moderately correlated with CRP (r =0.58,P ＜ 0.01 ),and weakly correlated with the simplified CDAI (r =0.40,P ＜ 0.01 ).ConclusionSerum CRP and the simplified CDAI cannot replace Lewis score for capsule endoscopy in the assessment of disease activity in small bowel CD.However,CRP may be considered as an inflammatory marker for evaluating the moderate to severe capsule endoscopic activity.

Objective To investigate the expression of apoptotic protease cysteinyl aspartate specific proteinase (caspase-3) in cortex neurons of rats with sepsis.Methods Models of rats with sepsis were established by the cecal ligation and puncture (CLP).Totally 70 cases of 30-day-old male Wistar rats were randomly divided into CLP group (n =50) and control group (n =20).In CLP group,CLP was performed in the rats.Neurobehavioral score was measured in 5 rats at 6,12,24 and 48 h after CLP surgery,respectively.Then,they were killed and their brains were removed.The immunohistochemical staining and Western blot were used to detect the apoptotic protein caspase-3 expression in cortex of rats.Control group did not undergo CLP,and the other treatment was the same as CLP group.Results Neurobehavioral scores at 12,24 and 48 h after CLP surgery were significantly lower than that in the control group(t =3.651,3.773,7.155,all P ＜ 0.05),and the scores were gradually decreased,overall situation of rats was getting worse along with the time.Caspase-3 protein expressed only in trace amounts in rat cerebral cortex in the control group by immunofluorescence analysis,however,its expression was significantly increased at 12 h after CLP surgery.Western blot test showed that caspase-3 protein expression in rat cerebral cortex at 6,12 and 24 h after CLP surgery was significantly higher than those in control group (all P ＜ 0.05).Its expression began to increase at 6 h after CLP surgery,and reached the peak at 12 h,then decreased at 48 h.Conclusion The neurobehavioral scores decreases and the expression of apeptosis protease caspase-3 increases in cortex of rats with sepsis brain injury.

Objective To evaluate the diagnostic value of virtual touch tissue quantification (VTQ) in the diagnosis of renal allograft fibrosis.Methods The renal allografts of 82 patients with biopsies or nephrectomy were assessed by virtual touch quantification.The renal allograft fibrosis was categorized according to the 2005 updated Banff criteria for a G0～G3 grade.All the results were compared among four groups.Results The mean SWV values in G0～G3 were (2.39 ± 0.31)m/s,(2.45 ± 0.34)m/s,(2.58 ± 0.18) m/s,(3.11 ± 0.40)m/s,respectively.There were no significant differences in the mean SWV value between G0 and G1 group,or between G1 and G2 group(P ＞0.05).There were significant differences in the mean SWV value between G0～G2 and G3 group,or between G0 and G2 group(P ＜0.05).Stiffness of renal allograft was significantly correlated to the mean SWV value (Spearman r =0.671,P ＜0.001).According to the area under the ROC curve,the sensitivity and specificity of SWV (area under ROC curve =0.847,cut-off=2.64 m/s) for grade ≥G2 was 78.9％ and 79.5％ respectively.Conclusions Stiffness measured by VTQ reflects the interstitial fibrosis in renal allograft.VTQ technique might be a new tool to identify patients with chronic allograft injury.

Objective To evaluate the value of quantitative analysis of contrast‐enhanced ultrasonography (CEUS) in differentiating acute rejection(AR) from acute tubular necrosis(ATN) of transplant kidney. Methods Total of 67 kidney recipients were examined with conventional US and CEUS. Biopsies were performed in 37 patients, 26 patients were with AR, 11 with ATN, 30 patients as control group. The hemodynamic parameters (PSV and RI) were measured on infrarenal artery with conventional US, while CEUS quantitative analysis was performed on the cortex, pyramid and interlobar artery by time‐intensity curve (TIC). TIC parameters including rise time (RT ), time to peak (TTP), mean transit time (mTT ) were compared among three groups. In addition, the reproducibility of TIC parameters was evaluated. Results The RI in AR group was significantly higher than that in control group, but there were no significant differences of RI between AR and ATN groups. TIC parameters including RT, TTP were with high reproducibility (ICC> 0 7.5). Compared to the other two groups, the RT and TTP of the pyramid, ΔRTm‐c, and ΔTTPm‐c were significantly longer in AR group, the receiver operating curves (ROC) analysis demonstrated that ΔRTm‐c had the highest accuracy and RI had the lowest accuracy for detecting AR(areas under the curve were 0 7.86, 0 7.56, 0 7.49, 0 7.36 and 0 4.98, respectively). High sensitivity and specificity(78 3.% and 73 5.%, respectively) were shown when using 4 6.2 s as a cutoff point of ΔRTm‐c to diagnose AR. Conclusions Quantitative analysis of CEUS could detected the changes of the microcirculation perfusion in kidney grafts with AR and ATN, which might be superior in the diagnosis of AR compared with conventional US.

Objective:To study immunosuppression mediated by the porcine FcγRⅢ in porcine reproductive and respiratory syndrome virus ( PRRSV ) infection to pulmonary alveolar macrophages ( PAMS ).Methods: In this study pulmonary alveolar macrophages cells were treated with containing 200 TCID50 PRRSV,lipopolysaccharide (LPS) (100 ng/ml) and purified mouse anti-pig FcγRⅢIgG (550 μg/ml) separately,simultaneously,PAM cells treated with purified mouse anti-pig FcγRⅢIgG (550 μg/ml) was infected by 200 TCID50 PRRSV ,untreated PAM cells as the control group.Each group were post-cultured 12,24,36,48,60,72 h, the cells and the supernatant were collected.The dynamic variation of PRRSV RNA copies in inoculation group were detected by using real-time fluorescence quantitative PCR method.mRNA level of IFN-αand TNF-αin each group were detected by using relative fluorescence quantitative PCR.Results:The result showed that mRNA level of IFN-αwas improved during PRRSV infection to PAMS 12-24 h,and mRNA level of IFN-αwas inhibited during 36-72 h,then mRNA level of IFN-αrecovered normally; mRNA level of TNF-αwas increased slightly post-infection 12-72 h.IFN-αand TNF-αmRNA levels of PAM cells treated with LPS were both up-regu-lated,using the purified mouse anti-pig FcγRⅢ IgG to treat the PAM cells,selective activation of porcine FcγRⅢ in the PAM cells down-regulated significantly mRNA levels of IFN-αand TNF-α.PRRSV infection assay mediated by selective activation FcγRⅢof the PAM cells inhibited antiviral cytokine ( IFN-αand TNF-α) mRNA levels.Conclusion:The results show selective activation of FcγRⅢinhibited significantly mRNA levels of the antiviral cytokine IFN-αand TNF-αof host cells,and innate antiviral immune response to PRRSV infection.

Interleukin-8 (IL-8) is an inflammatory cytokine with chemotaxis and there is a significant increase in the expression of IL-8 in autoimmune liver diseases. It participates in disease progression by binding to its receptors CXCR1 and CXCR2, promoting chemotaxis of inflammatory cells, angiogenesis, and fibrosis, and inducing cell proliferation. This article reviews the research advances in the association between IL-8 and autoimmune liver diseases.
