Objective To compare the efficacy of tamsulosin and nifedipine for the adjunctive expulsive therapy in patients with lower ureteral stones. Methods A total of 180 patients with stones (0.4-1.0 cm in diameter) located in the lower ureter (juxtavesical or intramural tract) were randomly divided into 3 groups (60 cases in each group). Group 1 served as controls; group 2 received nifedipine (10mg, 3 times daily) ; and group 3 received tamsulosin (0.4 mg, once daily). All patients were observed for 2 weeks. Results During 2 weeks, expulsion of stones was observed in 26 cases (43. 3% ) of group 1, in 44 (73. 3% ) of group 2, and 49 (81. 1% ) of group 3. The difference in expulsion rates between groups 2, 3 and group 1 was statistically significant (P 0. 05). In groups 1 , 2 and 3, renal colic recurred within 2 weeks and analgesics were used in 5 cases (8.3%), 1 (1.7% ) and 0, respectively, with significant difference between the groups (P

Objective To estimate the expressions of cyclin D1 and Ki67 in esophageal squamous cell carcinomas and their clinical significance. Methods The expressions of cyclin D1 and Ki67 were detected by immunohistochemistry in 28 specimens esophageal squamous cell carcinoma (ESCC) and 33 samples esophagitis tissue. Results The positive expression rate of cyclin D1 in ESCC and esophagitis tissues was 60.7% (17/28) and 33.3% (11/33) respectively (?2=4.573,P=0.032),while the mean Ki67 label index (Ki67 LI) was (49.21?25.15)% and (11.62?9.87)% respectively (t=7.908,P=0.000). The positive expression rate of cyclin D1 in TNM stage I tissues was 14.3% (1/7),which was significantly lower than that in stages Ⅲ and Ⅳ tissues[85.7% (6/7) and 100% (5/5),P=0.029 and 0.015,respectively]. In cases with lymph node metastasis,the positive rate of cyclin D1 expression was 90.9% (10/11) that was significantly higher than that in those without lymph node metastasis (P=0.016). The 28 patients with ESCC were followed up for 6 to 34 months [mean,(25.0?4.2) months],during which 19 patients survived,4 patients died of deterioration of the primary diseases (3 cases) or cerebrovascular affair (1 case),and the other 5 patients was lost to follow-up. Conclusions The expression of cyclin D1 is correlated with advanced tumor and lymph node metastasis. The Ki67 is highly expressed in ESCC tissues; no relationship exists between the level of the expression and the pathological differentiation type and TNM stage of ESCC.

Monoamine oxidase(MAO) is a kind of mitochondrial outer membrane enzyme that degrades biogenic amines,such as catecholamine and serotonin.It has a variety of biological functions,and can be found in various human tissues,including nervous system.Two MAO enzymes,MAO-A and MAO-B have been identified.MAO gene has polymorphisms,and some of which have a close relationship with certain psychic diseases,such as major depression,alcoholism,antisocial personality disorder and so on.MAO gene can acts as a new forensic individual identification and parentage testing genetic marker or legal psychiatry testing referential genetic marker.

Objective:To develop the Abusive Behavior Scale for Superiors under the Chinese context (ABSSC) and test its validity and reliability.Methods:Based on literature analysis and the open questionnaire survey in 32 employees,this study defined the construct of ASBSS,and compiled the preliminary questionnaire.A sample of 200 employees coming from companies was selected for item analysis.A sample of 445 employees was investigated with this questionnaire,223 of them were assessed for exploratory factor analysis and 222 of them were assessed for confirmatory factor analysis and internal consistency test with 2 week interval.Results:The ABSSC consisted of 11 items in 3 factors,which were neglect and slander,obstructionism and hard on subordinates.The 3 factors explained 55.45％ of the total variance.Furthermore,the result of CFA indicated that the model fitted the data with well constmct validity (RMSEA =0.06,GFI =0.94,NFI =0.92,CFI =0.96,IFI =0.96).The Cronbach α coefficient of the whole scale and its three facts were 0.87,0.79,0.78,and 0.76,respectively.Conclusion:It suggests that the Abusive Behavior Scale for superiors under the Chinese context (ABSSC) is reliable and valid enough to be applicable to measure superiors' abusive behavior under the background of Chinese culture.

Objective To summarize the imaging characteristics and clinical diagnostic value of computed tomography (CT) examination in colon cancer combined with obstruction.Methods The clinical data of 33 patients with colon cancer combined with obstruction who were admitted to the Wuxi No.2 People's Hospital from June 2012 to March 2015 were retrospectively analyzed.All the patients received abdomianl plain scan and dualphase enhanced scan of CT,and the imaging data were summarized.Results Of 33 patients with colon cancer combined with obstruction,obstruction was located at the ascending colon in 9 patients,hepatic flexure of the colon in 2 patients,colon transverse in 7 patients,splenic flexure of the colon in 3 patients,descending colon in 3 patients,sigmoid colon in 7 patients and proctosigmoid in 2 patients.Thirty-three patients had irregular and thickened colonic wall at the obstructive segment and irregular constriction of colonic lumen,with a mean coloric wall thickness of 1.9 cm (range,0.6-3.2 cm).The length of constriction was 2.0-3.0 cm in 3 patients,3.1-4.0 cm in 3 patients,4.1-5.0 cm in 11 patients,5.1-8.0 cm in 12 patients and more than 8.0 cm in 4 patients.The mean length,diameter and mean diameter of the constriction of 33 patients were 5.8 cm,0-0.5 cm and 0.2 cm.The performance at the junction of the normal wall and the stenosis was scuff syndrome in 7 patients and shoulder symptoms in 5 patients.Colonic dilatation above the obstructive segment was detected in 26 patients with multiple gas-fluid levels and in 7 patients with mainly gas.Twenty-nine patients had colonic dilatation at the proximal end of obstruction with the diameter of right colonic dilatation of 6.0 cm,diameter of left colonic dilatation of 4.0 cm and colonic collapse at the distal end of obstruction.Thirty-three patients had different grades of cecal dilatation with a mean diameter of 6.9 cm.Three patients had ischemic colitis including 1 patient with colonic perforation and free underarm gas.The serosal invasion or organ involvement of colon cancer was detected in 25 patients with unclear boundary and cable-strip or nodular opacities.Fourteen patients had lymph node metastases,with surrounding tumor or retroperitoneal heterogeneous enhancement,sacvariable necrosis area,short-tempered edge of lymph node,bar-type exudation surrounding some of lymph node.There was 3 patients with hepatic metastases and 1 with pulmonary metastasis.Conclusion Irregular and thickened colonic wall,irregular constriction of colonic lumen,scuff syndrome and shoulder symptoms at the junction of the normal wall,colonic dilatation above the obstructive segment and multiple gas-fluid levels are mainly characterics of CT examination for colon cancer combined with obstruction.

In order to investigate the clinical value of multi-slice computed tomography (MSCT) in the diagnosis of colonic neoplasms,the clinical data of 57 patients who were confirmed as with colonic neoplasms were admitted to the Wuxi No.2 People's Hospital from June 2013 to June 2014.Patients received plain and enhanced scan of MSCT,multiplannar reconstruction (MPR),sliding thin-slab maximum intensity projection (STS-MIP) and curved planar reformation (CPR),and the results of these examinations were compared with the postoperative TNM stage.Of the 57 patients,tumors located at the cecum in 1 patient,ascending colon in 23 patients,hepatic region of the colon in 9 patients,transverse colon in 11 patients,splenic region of the colon in 1 patient,descending colon in 3 patients and sigmoid colon in 9 patients.The results of the CT examination were in accordance with the results of exploratory laparotomy.The wall of the intestine was irregular ring-like thickened in 57 patients.The thickening of the intestine ranged between 0.6-3.2 cm,and patients had intestinal stricture in different degrees.Sixteen patients had gas-fluid level and dilatation of the intestine and were presented with intestinal obstruction signs.Forty-two patients had nodular or mass shadow in sofi tissues,and the nodules or mass protruded into the intestinal cavity or outside of the intestinal cavity,and resulting in intestinal stricture.The junction of the mass and the adjacent intestinal wall was blurred or clear,and the thickness of the intestinal walls was normal.Carcinomatous ulcer was observed in 20 patients.The shape of the ulcer was crateriform.The serosa and (or) adjacent organs were invaded by the tumors in 47 patients.Twenty-seven patients had lymph node metastasis,including 6 had distal metastasis,4 had hepatic metastasis and 2 had pulmonary metastasis.The sensitivity and accuracy of the preoperative CT examination for T stage were 100.0％ (57/57) and 77.2％ (44/57),respectively.The sensitivity,specificity and accuracy of the CT examination for N stage were 67.9％ (19/28),72.4％ (21/29) and 70.2％ (40/57),respectively.The sensitivity,specificity and accuracy of the CT examination for M stage were 100.0％ (6/6),100.0％ (51/51) and 100.0％ (57/57),respectively.The results of CT examination for TNM stage were well correlated with the pathological examination for TNM stage (κ =0.592,0.514,1.000,P ＜0.05).MSCT scanning and post-processing technique are of important clinical value in depicting tumor location,size and morphology,delineating tumor extension,revealing lymph nodes and metastases,and confirming preoperative tumor TNM stage in patients with colonic neoplasms.

OBJECTIVE:To investigate the correlation of total saponins and total polysaccharides content in the roots of Pari-dis rhizoma genus plants with Arbuscular mycorrhizal fungi(AMF)infection rate and rhizosphere soil nutrients. METHODS:Tak-ing 16 pieces of Paridis rhizoma herbs and rhizosphere soil in Three Gorges Reservoir Area as the research object,mycorrhizal in-fection rate and infection intensity,the contents of total saponins and total polysaccharides in roots and stem,and rhizosphere soil nutrient contents were all determined. SPSS18.0 software was adopted for data multiple comparison and correlation analysis. RE-SULTS:Paridis rhizoma genus plants roots in Three Gorges Reservoir Area could form a good symbiotic relationship with AMF. In-fection rate ranged from 85.19% to 99.80%,and infection intensity ranged from 16.55% to 72.27%. Paridis rhizoma from differ-ent origins and varieties had significant difference in the contents of total saponins and total polysaccharides (P<0.05). Soil pH was moderate,the average content of total nitrogen was in insufficient level,the average concentration of the remaining nutrients belonged to middle levels or above. Correlation analysis showed that the mycorrhizal infection rate and infection intensity of Paridis rhizoma were not significantly correlated with its quality. The total saponins were significantly negatively correlated with organic matter and available nitrogen. The total saponins and total polysaccharides were positively correlated with available phosphorus,po-tassium and pH value,but they were not significantly correlated with the other soil nutrients. CONCLUSIONS:Paridis rhizoma is selective to different soil nutrients. Rich soil available phosphorus and potassium supply are in favor of the synthesis and accumula-tion of total saponins and total polysaccharides in Paridis rhizoma roots.

2 cm).Immunohistochemistrical stain slice of operative specimen showed a lots of vascular endothelial cells and small vessels,which correlated with the tumor angioimaging area on CT images.The sensitivity,specificity,and positive predictive valve of tumor angioimaging in the lung cancers were 47.2%,91.3%,and 95.5%,respectively.Conclusion The “tumor angioimaging” sign can be regarded as another specific feature in peripheral lung cancer with contrast CT.

Objectives To investigate the pathophysiologic mechanisms and the clinical character- istics and variations of nutcracker esophagus(NE).Methods Clinical data obtained from 22 patients with NE were retrospectively analyzed.Seven followed-up patients had esophageal motility,multi-channel electrogastrography(MEGG),the autonomic nervous system(ANS) and psychology tests and were com- pared to 10 healthy subjects(HS).Results①In NE group,12 patients had reflux symptom(55%),7 patients had chest pain(32%)and 3 patients had dysphagia(13%).There was no statistical difference in mean contraction amplitude(MCA) between patients with reflux symptom and chest pain.②Eight out of the 13 patients with NE who received 24 h pH monitoring were positive reflux,and 4 out of 17 patients had reflux esophagitis in endoscopic examinations.The symptoms were improved in 58%patients(7/12) by regular acid-suppression therapies.③There was no statistical difference beween NE and HS groups in dominant frequency and power of MEGG.However,the percentages of normal rhythm in preprandial and slow wave coupling in pre and postprandial of NE patients were significantly decreased than those in HS.④The ANS function in NE group had no statistical difference compared to those in HS.⑤In follow- up group,no difference was found before and after nitroglycerin sublingually.Four patients had depres- sion.Conclusions The clinical presentations of NE are vary.The symptoms of NE were poorly correla- ted with MCA,but partially correlated with GER,which may represent a special subtype of GERD. Gastric dysmotility and psychological factors might contribute to the pathogenesis of NE.
