1.Pathological Observation on 90 Cases of Bladder Transitional Cell Carcinoma and Its Prognosis
Journal of Third Military Medical University 1984;0(01):-
Ninety specimens of pathologically confirmed transitional cell carcinoma of the urinary bladder were studied. The patients consisted of 71 male and 19 female with a male/femai ratio of 3.5:1. Their age was ranged from 32 to 79. 12 specimens were studied with electron microscope. The histopathological and ultrastructural features of transitional cell carcinoma were described. Our fol-lowup data of the cases revealed that the larger a tumor,the lower its differentiation, the deeper its invasion, and the more extensive the involvement of lymphatic and blood vessels, the poorer the prognosis of the tumor. In addition the ultrastructural characteristics of transitional oell carcinoma were briefly discussed.

Objective:To evaluate the effectiveness of hierarchical management for patients with bronchial asthma.Methods:One hundred and eighty seven patients with bronchial asthma were recruited from January 2018 to November 2019 in Daxing District People′s Hospital. Patients were randomly divided into two groups, 94 patients received disease management education and therapeutic guidance from doctors in the community hospital and district hospital (study group), and 93 patients were followed up in outpatient visits only (control group). After one year, the scores of inhalation technique, treatment adherence, disease management awareness, the Asthma Control Test (ACT), the Mini Asthma Quality of Life Questionnaire (MiniAQLQ) and pulmonary function were evaluated and compared between two groups. The annual acute attack times and time to first exacerbation were also compared between the two groups.Results:After one year of management the treatment adherence rate in study group was higher than that in control group [80.85% (76/94) vs. 51.61% (48/93), χ2=2.834, P=0.02]. The scores of inhaled corticosteroids (ICS) inhalation technique [(6.47±1.28) vs. (4.05±1.37), t=2.241, P=0.04], the correct rates of exhaling before ICS inhalation [94.68% (89/94) vs.56.98% (53/93), χ2=4.436, P=0.01],inhalation [90.43%(85/94) vs.68.82% (64/93),χ2=2.943, P=0.04],holding breath after inhalation [89.36% (84/94) vs.58.06% (54/93),χ2=4.098, P=0.02],rinsing mouth after ICS inhalation [92.55%(87/94) vs.65.59%(61/93),χ2=2.876, P=0.04] in study group were higher than those in control group. The awareness rates of chronic inflammatory airway disease [70.21%(66/94) vs.44.08% (41/93),χ2=2.673, P=0.02], causative factors [85.10% (80/94) vs. 56.99% (53/93),χ2=2.760, P=0.02],treatment misunderstanding [88.29%(83/94) vs.53.76%(50/93),χ2=4.874, P<0.01], therapeutic goal [86.17% (81/94) vs. 49.46% (46/93),χ2=4.491, P<0.01] and requiring long-term treatment [90.43% (85/94) vs.48.38% (45/93),χ2=4.503, P<0.01] in study group were higher than those in control group. The scores of ACT [(22.71±2.81) vs. (19.50±5.34), t=2.041, P=0.04] and miniAQLQ [(84.28±11.16) vs. (64.23±14.38), t=3.298, P<0.01] in study group were higher than those in control group. The number of annual acute exacerbation was less [0(0, 1) vs.2(1, 3), Z=-3.237, P<0.01] and the time to first exacerbation was longer [184(96, 284)d vs. 96(59, 177)d, Z=3.873, P<0.01] in study group than those in the control group after one year of management. Conclusion:The hierarchical management can effectively enhance the inhalation technique and treatment adherence of the patients with bronchial asthma, and improve the quality of life of patients.

ObjectiveWe conducted a drug resistance and homology analysis of diarrheagenic Escherichia coli (DEC) in Fengxian District of Shanghai in order to provide a basis for clinical rational drug use, risk monitoring and early warning. MethodsDEC were isolated from diarrheal patients in Fengxian District, Shanghai from 2019 to 2022. The minimum inhibitory concentrations (MIC) of 21 drugs to the DEC were determined. Genotyping and homology analysis were conducted with pulsed-field gel electrophoresis (PFGE). ResultsThe DEC detection rate of diarrhea cases was 18.99% (131/690), including enteroaggregative E.coli (EAEC) 64.89% (85/131), enterotoxigenic E.coli (ETEC) 22.14% (29/131), enteropathogenic E.coli (EPEC) 12.21% (16/131), and enterohemorrhagic E.coli (EHEC) 0.76%(1/131). The DEC detection showed obvious seasonal characteristics with a high incidence in summer. The DEC multidrug resistance rate was 66.41% with a total of 65 drug resistance profiles. The five antimicrobial drugs with the highest resistance rate were ampicillin (60.31%), nalidixic acid (51.91%), cefazolin (50.38%), tetracycline (44.27%), and cotrimoxazole (35.11%). The rate of DEC resistance to levofloxacin was significantly increased from 2019 to 2022. Cluster analysis showed that the similarity of 85 EAEC cluster was 58.4%‒100.0%, and 69 band patterns were obtained. The similarity of 29 ETEC cluster was 58.5%‒100.0%, and 13 band patterns were obtained, including 2 dominant band types. The similarity of 16 EAEC clusters was 53.9%‒100.0%, and 15 band patterns were obtained. Five groups of homologous strains were found, consistent with the resistance phenotypes. ConclusionAmong the diarrhea cases, the DEC epidemic intensity is high, the drug resistance situation is severe, and the risk of outbreak infection is high in Fengxian District, Shanghai. Therefore, health monitoring and prevention need to be strengthened.

A method was developed for determination of thirteen amines including seven aliphatic amines, two heterocyclic amines and four aromatic amines in atmospheric particulate matter (PM) by gas chromatography-mass spectrometry (GC-MS). Samples were ultrasonically extracted with ultra-pure water and derivatized with benzenesulfonyl chloride (BSC) under alkaline conditions. The derivatives were extracted with dichloromethane and then detected by GC-MS using DB-5MS chromatographic column. The method detection limit (S/N=3) and quantitation limit (S/N=10) were 0.00008-0.017 μg/mL and 0.00026-0.0565 μg/mL respectively, and the correlation coefficients were 0.9903-0.9996, which indicated that the standard curve had good linear correlation. In addition, the relative standard deviation was less than 30% and the average recovery was 54.4%-159.7% except for methylamine and benzylamine at spiked level of 1.0 μg/mL, showing high precision and accuracy. 9 kinds of amines were detected in the PM2.5 samples collected in Guangzhou city by this method, among which dimethylamine and butylamine accounted for 90% of the total nine amines, which indicated that they were primary amines in PM2.5; while propylamine exhibited the lowest level in PM2.5 with the concentration less than 1.0 ng/m3.

ObjectiveTo study the treatment and prognosis of the breast phyllodes tumors.MethodsKG1Clinical data, and the results of follow-up in 203 cases of breast phyllodes tumors were analyzed using Logistic analysis and Cox regression in SPSS statistic software.ResultWT5”BZLocal recurrence and tumor mortality were in direct proportion to the pathologic grade of the tumor. There was a direct proportion between local recurrence and tumor infiltration; and between tumor caused-mortality and tumor mitosis and necrosis.Mitotic activity and tumor necrosis were the independent prognostic factors. After surgical resection 21 1% of patients with benign tumor, 45 2% of patients with borderline tumor, 64 3% of patients with malignant tumor suffered recurrence. The 5-year survival rate was 100% in patients with benign phyllodes tumor, 92 0% with borderline tumor, and 33 3% with malignance.KG2Conclusion Local excision is not the appropriate treatment for phyllodes tumor. Patients with benign or borderline phyllodes tumor should undergo wide local excision including a margin of uninvolved tissue, and that with local recurrent borderline and malignant phyllodes tumor receive mastectomy.
