Objective To understand the clinical characteristics of patients with advanced schistosomiasis in Yingcheng City,so as to provide evidences for the assistance work of advanced schistosomiasis. Methods The clinical data of all the ad?vanced schistosomiasis patients in Yingcheng City were collected and analyzed. Results Up to December 30,2014,there were 96 advanced schistosomiasis patients in Yingcheng City,among which,68 cases(70.8%)were male,28 cases(29.2%) were female,and their average age was 64.2 years. Most of the patients(90.6%)were ascitic type,followed by splenomegaly type(5.2%),colon proliferation type(2.1%),and dwarf type(2.1%). Totally 48 cases(50.0%)were positive in immunologi?cal detections,among which 8 cases(8.3%)were positive in ELISA and 12 cases(12.5%)were positive in IHA. For all the 4 indexes of hepatic fibrosis(HA,LN,CIV and PCⅢ),only 15 cases(15.6%)were normal. Conclusions Though Yingcheng City has reached the criteria of transmission control,the hepatic fibrosis of some patients continues to progress. Therefore,the intensity of the treatment and assistance could not be weakened,especially for those of the ascitic type patients.

OBJECTIVETo investigate the relationship between (GT)n polymorphism and esophageal cancer by analyzing the connection between microsatellite polymorphisms in the promoter of heme oxygenase-1 and the clinicopathological characteristics of esophageal squamous cell carcinoma (ESCC) in Han chinese population.

METHODSThe (GT)n repeats in HO-1 gene in 83 male and 43 female hospital-based patients with ESCC (aged between 40 and 79 years with a mean of (61 ± 8) years) and 134 healthy control individuals were obtained by DNA sequencing. Polymorphisms of the (GT)n repeats were generally grouped into three classes based on allele frequencies: class S alleles (<25 repeats), class M alleles (25 to 29 repeats), and class L alleles (≥30 repeats). The correlation between susceptibility and clinicopathological characteristics of ESCC were analyzed by χ2 test. For in vitro experiments, the transient-transfection assay was performed to explore the correlation between different lengths of (GT)n repeats and promoter activity by assessing the promoter activities of HO-1 gene in cultured Ecal09 cells treated with H2O2 by analysis of cariance.

RESULTSHigher frequencies of L-allele (25. 8% vs. 14. 9%, χ2 = 9. 520, P = 0. 002), L-allele carrier (41. 3% vs. 27. 6%, χ2 = 5. 381 , P = 0. 020) were found in patients with ESCC. Furthermore, the lymphatic metastasis rate (63. 5% vs. 41. 8%, χ = 5. 685, P = 0. 017) and the detection rate of poorly differentiated ESCC cell (53. 8% vs. 28. 4%, χ2 = 8. 335, P = 0. 004) was significantly higher in L-allele carriers compared to non-L-allele carriers. In transfection experiments, promoter activities of 5'-flanking regions of the HO-1 gene in Eca109 cells transfected with the recombinant gene carrying (GT)16 repeat after treatment with H2O2 increased (F = 23. 615,P = 0. 008). In H2O treated control group, compared to (GT)26 and (GT)36, the basal promoter activities of HO-1 gene carrying (GT)16 repeat increased (F =41. 376, P = 0. 003; F = 50. 761, P = 0. 002).

CONCLUSIONThe long (GT)n repeats of HO-1 gene promoter can increase the susceptibility of esophageal squamous cell carcinoma and the risk of lymphatic metastasis.

Objective To observe the therapeutic effects of lung transplantation for diffuse pulmonary disease. Methods From September 2002 to April 2009, lung transplantation was performed on 72 cases in our hospital. Thirty-seven cases of these recipients were suffered from diffuse pulmonary disease, including idiopathic pulmonary fibrosis (30/37), pneumosilicosis (4/37), vascular leiomyoma (2/37) ,diffuse panbronchiolitis (1/37),30 males and 7 females with age ranging from 22 to 73 years old (mean 52.9 ± 13.2). All the patients received pulmonary function test and echocardiography (ECHO) to test the pulmonary artery systolic pressure before transplantation and artery blood gas to calculate the oxygenation index (PaO2/FiO2 ). Results The systolic pulmonary artery pressure (Ppa,syst) was monitored by Swan-Gans catheterization one week post-transplant, and decreased significantly from 54. 30 ± 17. 41 to 41.52 ± 9. 36 mm Hg (P＜0. 05). Simultaneously, oxygenation index was improved from 185. 89 ± 77. 25 to 392. 12 ± 98. 23 (P＜0. 05). The pulmonary function was also improved significanzly one month post-operation. The volume in the first second was improved from (1.33 ± 0. 64) to (1.81 ± 0. 57) L, and the diffusion capacity of carbonmonoxide was increased from (2. 87 ± 1.26) to (4. 22 ± 2. 05) L. Conclusion Lung transplantation is feasible and efficient to deal with diffuse pulmonary disease.

Objective To investigate diagnostic efficiency of vascular parameters in the diagnosis of BI-RADS Ⅳ breast masses using three-dimensional power Doppler ultrasound (3D-PDUS).Methods After adjusting the ultrasonic instrument under property conditions,3D-PDUS were applied to scan BI-RADS Ⅳ breast masses before surgery with QLab software,the following parameters of breast masses were obtained:total tumor volume,vascularization index (VI),flow index (FI),and vascularization flow index (VFI).According to the pathological results,the diagnostic value of vascular parameters from 3D-PDUS were assessed with receiver operating characteristic (ROC) curve,and the diagnostic efficiency were analyzed by best cut-off limits of various vascular parameters.Results The volume and vascular parameters of benign group were remarkably lower than those of malignant group (all P ＜0.001).The area under the ROC curve (AUC) of VI (0.873) ＞VFI (0.866) ＞FI (0.778).AUC of FI was significantly smaller than that of VI (P =0.016) and of VFI (P =0.039),while no statistical difference between that of VI and of VFI (P =0.294).The diagnostic accuracies of VI (cut-point:1.2,sensitivity:84.1％,specificity:83.3 ％,accuracy:83.8 ％) and of VFI (cut-point:0.5,sensitivity:82.5 ％,specificity:85.2％,accuracy:82.9％) were higher than that of FI (cut-point:35.3,sensitivity:74.6％,specificity:70.4 ％,accuracy:72.6 ％).AUC of VI (P =0.001) and of VFI (P =0.033) in small-volume group (＜2cm3) were both larger than those of large-volume group (≥2 cm3),no significant difference in AUC of FI between these two groups (P =0.09).Conclusions Vascular parameters obtained using 3D-PDUS have affirmative value in the diagnosis of BI-RADS Ⅳ breast masses,especially in masses less than 2 cm3 in volume.

Objective To measure volume of breast cancer , calculate tumor volume doubling time (TVDT), and analyze the correlated factors affecting TVDT using three-dimensional ultrasound (3D-US). Methods We applied 3D-US to measure the volume of breast cancer of BI-RADS-US 4A classified by conventional ultrasound. The breast cancer case scanned by 3D-US at least twice (the interval is 3 months at least) without any medical intervention were included in the study. We calculated TVDT according to the formula, and analyzed the affecting factors of TVDT using multiple linear regression. Results Sixty-nine cases were enrolled in the study. The TVDT of breast cancer were from 66 to 521 days , in an average of 185 ± 126 days and the median time of 164 days. We found that: ① there were no statistics significances in TVDT between different breast cancer pattern , smoothing border lines , speculated sign , hyperechoic halo , microcalcification and different rear echo (P > 0.05). ② TVDT of different age groups, lymph node metastasis, pathological grade and NPI score were significantly different (P < 0.05), while menstrual cycle, family history of breast cancer and molecular typing showed no difference (P > 0.05). ③ TVDT of patients with different expression of ER, PR and Ki-67, molecular typing showed statistically difference (P < 0.05), but there was no significant difference between different level of HER2 (P >0.05). ④ multi-factor analysis showed that the NPI score, lymph node metastasis, Ki-67 and molecular typing of breast cancer were relative factors in TVDT (P < 0.05). Conclusions The NPI score , lymph node metastasis , Ki-67 and molecular typing significantly correlate with TVDT of breast cancer. Triple-negative breast cancer in molecular typing has the fastest growth rate.

This study is to screen the Chinese herbal compounds which could inhibit the production of Abeta and investigate the underlying mechanism. Ten types of compounds which have potential value in the treatment of AD were selected as initial screening trial. The cell models which used could overexpress Abeta and beta-secretases or Abeta and gamma-secretases. Extracellular Abeta was determined by ELISA after the cell models treated with different concentrations of compounds (0.5-100 micromol x L(-1)), separately. Then the compounds were selected which could inhibit extracellular Abeta and their best concentration ranges were decided, too. Furthermore, the cell viability and apoptosis rate, the level of intracellular Abeta, beta and gamma-secretases were determined after the cell models treated with different concentrations of selected compounds. The results showed that 4 of the 10 compounds could reduce the level of extracellular Abeta; they were cryptotanshinone, astragalosides, gastrodin and paeoniflorin, and their best concentration ranges were 0.5-5.0, 0.5-5.0, 5.0-50, 1.0-25 micromol x L(-1), respectively. Further study indicated that the 4 selected compounds were nontoxic to the cellular models and lowering intracellular Abeta were more effective compared with extracellular; of which astragalosides and gastrodin showed dose-dependent inhibition to the activities of beta and gamma-secretases, with the maximum inhibiting rates of 78.2% and 80.3%, respectively. In conclusion, cryptotanshinone, astragalosides, gastrodin and paeoniflorin could inhibit the expression and secretion of Abeta, and the underlying inhibiting mechanism of astragalosides and gastrodin were related with the reduction of the beta and gamma-secretase activities, respectively.
