Objective To study the influence factor of recurrence in breast cancer.Methods The grouping treatment and tumor by stages,tumor transfer were observed in 105 cases with primary breast cancer.Results Among 105 patients,the inside of 2 years relapse was 47.6%(50/105);Tumor Ⅱ period recurrence rate was 40.0%(10/25),Ⅲ period recurrence rate was 28.0%(7/25);Among 105 cases,the distant place transfer to recurrence rate was 31.4%(33/105);Among 105 patients for surgical operation,its relapsing rate was 40.0%,but in 25 cases after operation putting radiation treatment,relapse rate was 16.0%;The part recurrence rate totally was 58.0%(61/105),among them the chest wall recurrence rate was 13.3%(14/105);The supraclavilar lymphonodes transfer was 20.9%(22/105),the axlla lymphnides transfer was 23.8%(25/105);The distant place transfer was 31.4%(33/105).Conclusion The recurrence rate of association treatment obviously is lower than that pure surgical operation,the relapsing of tumor with tumor by stages and transfer relevanted.

Objective To explore the effrciency of intra-arterial neoadjuvant chemotherapy before radical excision in patients with cervical cancer.Methods 50 cases with cervical cancer were enrolled into the study and were treated with a 2～3 course of intra-arterial neoadjuvant chemotherapy immediately after the pathological diagnosis.The regime included Then radical excision was performed in those who were good for the operation.Results Complete recovery(CR) was acquired in 12 patients and partial recovery(PR) in 26 patients.The total response rate was 76.0 %.The tumor size reduced significantly(P

Objective To explore the feasibility of low-dose multi-slice computed tomography(MSCT) scan on pulmonary artery three-dimensional angiography, and the relationship between pulmonary VR image quality and the SD value of plain scan. Methods Pulmonary artery CT examination was performed in 87 patients. 63 volunteers were administered with low dose as a low-dose group, and the other 24 were scanned with conventional dose as a routine group. Both plain scans were use conventional dose of pulmonary scan with 150 mAs, and the low-dose pulmonary enhanced scans were used with 60 mAs. The images were post-processed with volume rendering(VR) and classified into three grades A, B and C, and VR image quality levels of both groups compared. The receiver operating characteristic curve( ROC) was used to analyze the relationship between VR image quality level and SD value of plain scan image SD value. Results The VR image level of A-class was 100% in the conventional dose group, and 85. 7% was in the low dose group . According to the correlation analysis between the standard deviation(SD) value of plain scan image and pulmonary artery VR image quality, the area under curve in receiver-operated characteristic analysis was 0. 906. Conclusions The low-dose scan of pulmonary artery three-dimensional angiography is feasible. Using 60 mAs low-dose in pulmonary artery enhanced scan could ensure better image quality. With the SD value of the plain scan decreased, the pulmonary artery VR image quality is improved.

Objective To observe the effect of angiotensin-converting enzyme inhibitors (ACEI) on anemia and erythropoietin (EPO) requirements in maintenance hemodialysis patients. Methods Ninety maintenance hemodialysis patients with hypertension and anemia were divided into 2 groups by random digits table, observation group (45 cases, using ACEI as antihypertensive treatment), control group [45 cases,using calcium channel blocker (CCB) as antihypertensive treatment]. The follow-up period after starting ACEI or CCB therapy was one year. The hemoglobin concentration, serum EPO, EPO requirements were compared after 0, 2, 4, 6, 8, 10, 12 months' treatment. Results In response to ACEI, the mean hemoglobin value in observation group decreased progressively, reaching statistical significance after 6 months, and it had significant difference compared with that in control group [6 months: (94.21±9.20) g/Lvs. (105.55±9.16) g/L,12 months: (95.90±6.75) g/L vs. (105.81±4.45) g/L,P <0.05]. The EPO requirements experienced a progressive increase in observation group and reached statistical significance after 8 months, compared with those in control group [8 months: ( 10 090.75±1918.35) U/week vs. (7010.32±1600.15) U/week, 12 months: (11 586.39±2009.76) U/week vs. (7068.48±1615.35) U/week,P<0.05].Serum erythropoietin concentration remained stable during the study in two groups. Conclusion ACEI can worsen anemia and reduce the efficacy of EPO in maintenance hemodialysis patients.

OBJECTIVE: To evaluate the function of tubomanometry (TMM) in forcasting the progonosis of acute otitis media with effusion (OME). METHOD: We used the technique of TMM to quantify the degree of eustachian tube (ET) dysfunction in 65 patients with OME. The opening of the ET and the transportation of gas into the middle ear were registered by a pressure sensor in the occluded outer ear after applying the stimulus of a controlled gas bolus into the nasopharynx during swallowing. Three excess pressure values were tested subsequently (30, 40, and 50 mbar). If tube opening was registered, the time of opening in relation to pressure applied was measured. The TMM calculated the opening latency index or index R. An R value of < 1 indicated early opening of the tube at the start of application of the stimulus, which was considered optimal. A value > 1 indicated late opening of the tube occurring after the initial stimulus and was interpreted as suboptimal. Inability to calculate the index R value indicated that the tube was unable to actively open at all. The TMM results, were weighted as follows: no R with 0 points, R > 1 with 1 point and R < 1 with 2 points for the measurements at 30, 40, and 50 mbar, respectively. The points of these three tests were added so the ET score (ETS) ranges from 0 (worst value) to 6 (best value). According to the medical history, the patients were divided into two groups, chronic OME group (defined as positive control group), 30 cases with 38 ears; and acute OME group, 35 cases with 46 ears. The healthy ears of all patients were defined as normal control group, 46 cases with 46 ears. The same regular treatments, including classic medical treatments and intratympanic dexamethasone injections, were used to acute OME group in the following 1-2 months. On the basis of therapeutic effect, acute OME group was subdivided into valid group (26 cases with 33 ears) and invalid group (9 cases with 13 ears). RESULT: The ETS of normal control group was 5.11 ± 1.32 while it was 1.08 ± 1.32 in positive control group. It was found marked differences between the two groups (P < 0.01). The ETS of both valid and invalid subgroup of actue OME group were significantly lower than normal control group (P < 0.01), but in valid subgroup it was significantly higher than positive control group (P < 0.01), and no marked difference was found between the invalid subgroup and positive control group. After treatments, a significant improvement of the ETS was found in both valid and invalid subgroup (P < 0.05) there was no marked difference between valid subgroup and normal control group. But in invalid subgroup it was still significantly lower than normal cohtrol group (P < 0. 01). CONCLUSION TMM could forecast the prognosis of acute OME. Patients with acute OME suffered from ET dysfunction of varied degrees. Those with high ETS could be cured by classic medical treatments and intratympanic dexamethasone injections. But those with poor ETS could not be cured in short period, tube insertion should be considered. If ETS could not be improved by ventilation tube placement, more active treatment, for example, balloon Eustachian tuboplasty (BET), should be used to prevent transforming into chronic OME.

Objective To investigated the effects of long term use of very low protein diet(VLPD,0 3 g?kg-1?d-1) treatment on patients with chronic renal insufficiency without essential amino acids(EAAs) or related ketoacids supplement.Methods Thirty seven patients with established severe chronic renal failure (CRF)[Scr(588 2?123 5)?mol/L, Ccr(9 77?3 48)ml?min-1?(1 73m2)-1]were divided into 2 groups according to their actual protein intake: 20 patients with protein intake of (0 33?0 04)g?kg-1?d-1 were used as VLPD group, while other 17 CRF patients whose protein intake was 0 6 g?kg-1?d-1 were served as low protein diet group (LPD). Results All patients in VLPD group showed good compliance to this very low protein diet,and no one presented signs of protein malnutrition during the observation. The concentrations of serum albumin and transferrin were maintained in normal ranges during the follow up period despite the transferrin levels in both groups gradually decreased as time went on. The serum concentration of transferrin was higher in VLPD patients than that in LPD patients at the end of study (P
