Objective:To research the relationship of urinary cytology positive rate with the grade and stage of primary ureter uroepithelium cancer.Methods:A total of 104 cases of primary ureter uroepithelium cancer were recruited in this study.The urine of all paitents was collected for preoperative urinary cytology de-tection.The urinary cytology detection rates were compared among different grades and stages of primary ureter uroepithelium cancer.Results:The overall unnary cytology positive rate of primary ureter uroepithelium cancer was 34.26%.The overall urinary cytology positive rate was 43.59%in the advanced stage group and 11.54%in the low stage group,with a significant difference(X2=8.740, P=0.003).The difference in positive rate between the advanced stage group and the low stage group in the high grade with inferior segment group of primary ureter uroepithelium cancer was statistically significant(X2=10.628,P=0.001).The difference in positive rate between the advanced stage group and the low stage group in the high grade group of primary ureter uroepithelium cancer was statistically significant(X2=5.678,P=0.01 7).The difference in positive rate be-tween the high grade group and the low grade group in low stage group of primary ureter uroepithelium can-cer was statistically significant(X2=12.860,P=0.001).Conclusion:The unnary cytology positive rate of primary ureter uroepithelium cancer of high grade and low stage is higher.

Objective To investigate the clinical features of early postoperative inflammtory small bowel obstruction,and discuss its diagnosis,treatment and preventive measures.Methods The clinical data of 68 cases of early postoperative inflammatory small bowel obstruction were analyzed retrospectively.Results Within the 68 cases,65 cases were cured by non-operative treatment including gastrointestinal decompression,anti-inflammatory drugs,somatostatin,total parenteral nutrition(TPN) and traditional Chinese medicine.The mean time from the onset of symptoms to the recovery of bowel function was 14 days.Three cases were cured by transferring to operation.One case of them was transferred to operation for strangulated intestinal obstruction during the period of conservative treatment.One case underwent oper.ion because the patient didn t recover after 4 weeks expectant treatment.One case underwent operation for the impatience with the conservative treatment of both the doctors and the patient.Conclusion Non-operative therapy should be the first choice for the treatment of early postoperative inflammatory small bowel obstruction,and its therapeutical effect was well-accepted.

Objective To explore the clinical of value minimally invasive therapy for elderly gastric carcinoma patients with malignant obstructive jaundice after gastrectomy in improving the survival quality.Methods 12 gastric caecinoma patients with malignant obstructive jaundice after gastrectomy were treated by percutaneous transhepatic cholangial drainage(PTCD) plus biliary stenting.Results 12 patients were successfully accomplished the procedure of bile duct puncture and stenting.The life quality of 11 patients was promoted in varying degrees proved by reduced jaundice and normalization with transaminase level.One patient died of cardiac failure in a week.The one-year survival rate was 25 ％ (3/12),tow-year survival rate was 8.3 ％ (1 / 12).Complications occurred in 25 ％ of patients,including 1 case of hemobilia,and 2 cases of cholangitis.Conclusion The minimally invasive therapy of PTCD plus biliary stenting provided safe and effective bile drainage for elderly patients with malignant obstructive jaundice.

Objective To investigate the NOx(nitrogen oxides,esp.NO2) output of household ozone generator and the control method.Methods Ion chromatogram,pH detection and iodine titration were used to study the outputs of ozone and the by-product,NOx,generated by some certain household ozone generator in normal operation condition.The method of controlling NO2 simply by pure water absorption was also studied.Results At about 15 min,the ozone generator produced NO2 and turned into NO3-,the amount increased along with the operating time.After 60 min,the NO3-was almost in proportion to the operating time,the pH value decreased clearly.pH value was a proper and simple substitute parameter to display the generation and accumulation of NO2.NO2 could be efficiently controlled by pure water absorption.NO3-absorbed in a 0.1 mol/L NaOH solution was less than 0.01 mg/L after a pure water absorber which had an effective depth of 12cm,with little influence of ozone production.Conclusion NO2 will be generated inevitably and the amount of the by-product increases with the running time of the household ozone generator.Pure water absorption is efficient to control NO2 generation.

Objective To discuss effects of Wugong Baidu Drink on expressions of Bcl-2, NF-κB mRNA genes related to the apoptosis of HaCaT in psoriasis. Methods Wistar rats were randomly divided into 6 groups:blank group, Western medicine control group, TCM control group, and Wugong Baidu Drink high, medium, and low dose groups. They were given normal saline, methotrexate suspension, compound natural indigo capsule suspension, and the different doses of Wugong Baidu Drink for gavage, respectively. Drug-containing serum of each group was prepared, and was put in the HaCaT respectively to subculture. The intervention effect of different Drug-containing serums on expressions of objective genes were detected through PR-PCR method. Results Drug-containing serum of each group could decrease the expressions of Bcl-2 mRNA and NF-κB mRNA. The most obvious effects were shown in the groups of Western medicine control group and Wugong Baidu Drink high dose group. All Wugong Baidu Drink groups showed a dose-response relationship. Conclusion Wugong Baidu Drink probably can promote the apoptosis of HaCaT by reducing the gene expressions of Bcl-2 and NF-κB. It can also decrease immune response by regulating serum factors related to T cells to play the role of anti-psoriasis.
