Objective To understand the endemic situation of schistosomiasis after its transmission interruption in Baoying County,so as to provide the evidence for adjusting the prevention and control strategy. Methods The data of schistosomiasis surveillance in Baoying County from 1988 to 2015 were collected and retrospectively analyzed. Results The schistosomiasis surveillance has been established since it was interrupted in Baoying County in 1987. The total surveyed area with Oncomelania hupensis snails was 21 269.95 hm2,but no living snails were found. The number of schistosomiasis examinations of residents was 163 196 person?times,and 270 person?times were positive in serum test,26 person?times were positive in stool test. No positive cases were found since 1997. The number of schistosomiasis tests of livestock was 2 180 cattle?times but no infection was found. Conclusion No schistosome infected snails or livestock are founded in Baoying County for last 28 years,and no patients are founded for last 11 years. The effect of schistosomiasis control is steady.

Immunosenescence is a biological process featured by the structural and functional decline of immunity in ageing people,which favors the carcinogenesis by rendering the body's immune surveillance and tumor escape.Decreasing clearance of tumor cells by macrophages and natural killer cell reflects the immunosenescence of innate immune,also,the tumor antigen presentation ability of dendritic cell is decreased.While,the decline of the CD8 + T cells cytotoxic effect and the secretion of tumor growth factor accounts for the immunosenescence of adaptive immunity.Intervention of immunosenescence may produce the novelty ideas of prevention and treatment of cancer.

In view of the deficiencies of both Qi and Yin in most cases of this tumor, Jinfukang oral solution (JFK). a remedy mainly for benefiting Qi and nourishing -yin. was formulated. 96 cases were treated with one case of CR. 8 cases PR, 52 NC. the rate of PR + NC being 63. 5%. Another 52 cases were treated with chemotherapy +JFK. with 11 cases of PR, 26 cases NC, the rate of PR + NC being 71. 2%. While 25 cases were treated by chemotherapy alone, the cases of PR was 4; NC 26. the rate of PR + NC being 60. 0%, This demonstrated that the effect of JFK and JFK + chemotherapy were all superior to effect of chemotherapy alone. For 1 - and 2 - year survival rates, the JFK group was 67. 3% and 66. 7% respectively, whereas that of JFK + chemotherapy. 67. 3% and 66. 7%. For the chemotherapy group , 1 - year survival rate was 40. 3%, with no survivals within 2 years. For symptom improvement, body weight gaining, and health condition (KPS evaluation) after treatment, the JFK and JFK + chemotherapy groups were, again, superior to the chemotherapy group. The Immunity indices and blood picture in JFK group after treatment were markedly improved as compared with those before treatment, but, those in the chemotherapy group were decreased, while those of the JFK + chemotherapy group remained unchanged.

Objective To explore the effects of DNMT3b on the expression and methylation sta-tus of the promoter region of DLC-1 in human hepatocellular carcinoma cell line. Methods The SMMC-7721 cell line was divided into 2 groups. The cell line in the experimental group was transfect-ed with DNMT3b siRNA, while that in the control group was transfected with control siRNA. West-ern blot was used to detect the expression of DNMT3b and DLC-1 and MSP was employed to examine the methylation status of the promoter region of DLC-1. Results The expression of DNMT3b was significantly higher in the experimental group than in the control group, while the expression of DLC-1 was just opposite. There was no significant difference in the methylation status of the promoter re-gion of DLC-1 between the 2 groups and both were methylated. Conelnsion The inhibition of expression of DNMT3b by siRNA method can enhance the expression level of DLC-1, and the methylation status of the promoter region of DLC-1 does not change at the same time. When affecting the expression of DLC-1, DN-MT3b might not play the role of methyhransferase, but can act as a transcriptional regulatory factor.

The distribution of somatostatin (SRIF) in substantia gelatinosa of the rat spinal cord was studied by means of immuno-electron microscopy. The ultrastructural features showed that nerve terminals containing SRIF take part in forming presynap- tie elements of axe-somatic, axe-dendritic and axo-axonic synapses. The immune- reactive products locatl at the external membrane of mitochondria, around the small clear synaptie vesicles and in the large granular vesicles. Most of synaptic vesicles are round or ovoid in shape. Only a few of them are flattened. Based on the ultrastructural characteristics mentioned above and related experimental results the authors believe that SRIF in substantia gelatinosa of the rat spinal cord is probably involved as a neurotransmitter instead of neuromodulator.

Objective To explore the expression and significance of transforming growth factor-?(TGF-?),epidermal growth factor receptor (EGFR) and proliferation-related antigen Ki-67 in nephroblastoma. Methods Immunohistochemistry method was used to detect the expression of TGF-?,EGFR and Ki-67 in 8 cases of normal kidney,35 cases of nephroblastoma and 14 cases of the tissues adjacent to nephroblastoma.The differences of their expression were compared among the 3 kinds of tissues and different pathologic characteristics of nephroblastoma. Results The expression rates of TGF-?,EGFR and Ki-67 in nephroblastoma were 51.4%(18/35),62.9%(22/35) and 68.6%(24/35),respectively,which were significantly higher than those in the tissues adjacent to nephroblastoma and the normal kidney;the differences were significant (P0.05);but positive relationship was found between the expression and clinical stages (P

Objective To evaluate the effects on the mineral bone disorder using different calcium concentration citrate-based dialysate in maintenance hemodialysis (MHD) patients.To compare the concentrations of intact parathyroid hormone(PTH) with biointact PTH(1-84) in these patients.Methods Citrate dialysate with different calcium concentration (DCa 1.75,DCa 1.5,DCa 1.25 mmol/L)were used in turn in 15 stable MHD patients each week.Serum tCa and iCa were measured by automatic biochemistry analyzer.The concentrations of iPTH and bio-iPTH were compared.Results (1) The patients treated with DCa 1.75 citrate dialysate had increased serum iCa and tCa after dialysis,and PTH did not change significantly as compared to those findings before the dialysis.With the DCa 1.5 citrate dialysate,serum iCa and tCa were kept stable and PTH level was increased.With DCa 1.25 citrate dialysate,serum iCa and tCa decreased significantly and PTH decreased.(2)iPTH and bioPTH had excellent correlations.Variation of bio-iPTH was more correlated with the changes of calcium than iPTH.Conclusions Serum levels of iPTH,tCa and iCa can be kept stable in MHD patients treated with DCa 1.75 ～ 1.5 citrate dialysate.Bio-iPTH is a more sensitive marker for mineral bone disease than iPTH.

Objective To determine the normal position of the fetal conus medullaris and assess its clinical significance.Methods A total of 550 singleton pregnant women who were examined by fetal ultrasonography in the Department of Ultrasound at the Second Hospital of Fujian Medical University from June 1, 2013 to September 31, 2014 were included.Inclusion criteria were pregnancies with regular menstruation cycle and known last menstrual period, gestational age (GA) confirmed by ultrasonographic examinations, and neonate abnormality excluded by pediatrician after born.Routine obstetric ultrasound examinations were performed to measure the biparietal diameter (BPD), femur length (FL), head circumference (HC) and abdominal circumference (AC).The conus distance (CD) was determined by measuring the distance between the distal end of the conus medullaris and the caudal end of the last vertebra.The average value was calculated for each group according to GA.Fifty normal fetuses were randomly selected for quality control.For inter-observer reliability assessment, the same data were collected and analyzed by two different operators.For intra-observer reliability assessment, the data were collected and analyzed twice by the same operator with an interval of half an hour.Linear regression correlation analysis was performed to analyze the relationship between CD and GA, BPD, FL, HC and AC.Intraclass correlation coefficient (ICC) and Bland-Altman analysis were used to analyze the repeatability of the analysis.Results In 518 (94.2％) of 550 fetuses, the CD was successfully measured.Positively correlations between the conus distance and the gestational age was observed.The CD was (10.0± 3.3) mm at ＞ 14-≤ 15 weeks (n=17), (27.7±3.8) mm at ＞ 20-≤ 21 weeks of gestation (n=18), (41.5±2.4) mm at ＞ 26-≤ 27 weeks (n=8), (54.7±3.0) mm at ＞ 32-≤ 33 weeks (n=17), and (71.9±2.7) mm at ＞ 41-≤ 42 weeks (n=6).Linear regression correlations between CD (mm) and FL, AC, HC, BPD and GA were:CD=1.04× FL (mm)-8.71, CD=0.23 × AC (mm)-10.11, CD=0.28× HC (mm)-18.10, CD=0.90× BPD (mm)-17.65, CD=2.34× GA (weeks)-20.94 (r=0.990, 0.985, 0.978, 0.974 and 0.973, respectively, all P ＜ 0.01).The measurement of the conus distance exhibited good reproducibility between different operators (ICC=0.984, 95％CI: 0.972-0.991) and for the same operator (ICC=0.992, 95％CI: 0.985-0.995) with the 95％ limits of agreement of-1.8 to 3.5 mm and-4.3 to 2.1 mm.Bland-Altman analysis showed that most of the measured values were within 95％ confidence interval suggesting good consistency.Conclusions The distance, between the end of the conus medullaris and the end of the last vertebral body under ultrasound scan, is positively correlated with FL and other ultrasonographic indicators, which implies that it could be used as a new index for position of fetal conus medullaris.

Objective To assess the prediction value of nonbronchial systemic arterial supply in hemoptysis patients with non-enhanced CT. Methods Fifty-six consecutive patients with hemoptysis underwent non-enhanced CT. Thickness of pleural adjacent to parenchymal lesion larger than 3 mm was regarded as index of nonbronchial systemic arterial supply. Conventional angiography was used as the standard of reference. CT findings were compared with those of conventional angiography. The sensitivity, specificity, and accuracy of CT for predicting nonbronchial systemic arterial supply were assessed. Results The sensitivity, specificity and accuracy of CT for predicting nonbronchial systemic arterial supply were 72.73%, 95.00% and 91.11%, respectively. Sensitivity was higher when nonbronchial systemic arterial supply located in superolateral and posterolateral lung, and lower in anteromedial and inferior lung. Specificity and accuracy were high for predicting nonbronchial systemic arterial supply in every locations. Conclusion Non-enhanced CT can predict nonbronchial systemic arterial supply in patients with hemoptysis, which is helpful for selecting angiography and embolization.
