Objective:This study aimed to analyze the prognostic factor of bilateral hydronephrosis caused by advanced cervical cancer and evaluate its value of treatment. Methods:A total of 40 patients with bilateral ureteral obstruction secondary to cervical cancer were diagnosed through computerized tomography, radioactive nephrogram, and blood tests for renal function. The placement of retrograde internal double-J ureteral stents was performed under a cystoscope in 13 patients. The placement of antegrade internal double-J ureteral stents via percutaneous nephrostomy was performed in 25 patients. Two cases had external ureteral stents via percutaneous nephrostomy. Twenty-nine patients underwent radiotherapy after normalization of their blood urine nitrogen and creatinine levels. The prognostic value of the treatment and renal function before placement of ureteral stents and radiotherapy after placement of ureteral stents were analyzed. Results:The normalization rate of renal function after ureteral stenting was 91.3%(21/23). The median survival time was longer in patients with untreated cervical cancer than that in patients with recurrent cervical cancer (χ2=9.379, P=0.009). After ureteral stenting, the median survival time was longer in patients who underwent radiation therapy than that in patients untreated with radiation (χ2=17.329, P=0.000). The median survival time was not significantly influenced by renal function before placement of ureteral stents (χ2=1.37, P=0.242). Conclusion:The patient with bilateral ureteral obstruction from untreated cervical cancer or from recurrent pelvic disease after surgical therapy should be considered for ureteral stenting followed by appropriate radiation.

Objective To investigate the clinical effect of using leukocyte filter to prevent nonhemolytic febrile transfusion reactions(NHFTR) in hematologic patients who were trarisfused erythrocyte suspension. Methods Select 720 inpatients need erythrocyte transfusion and have transfusion records. The patients were randomly divided into investigation group and control group. We made a routine examination and recorded the patients' body temperature, heart rate, blood pressure, respiration rate and transfusion adverse reaction before and after erythrocyte suspeusion transfusion. Results Before blood transfusion, the body temperature of patients between two groups were normal, but after blood transfusion, there were 35 patients with NHFTR in the control group, while only 5 cases in the investigation group which used leucocyte filter, the difference between two groups is significant( P<0.01 ). The change of the patients' body temperature were compared between two groups before and after transfusion, the changes in the control group was significantly higher than the investigation group( P<0.01 ). Compared the changes of serum total bilirubin level in all patients before and after transfusion,there was no difference in both groups. The incidence of NHFTR increased with increasing of the transfusion times, but compared with the investigation group,the incidence of the control group was higher significantly(P<0.01 ). Conclusion Leukocyte filter can prevent the occurring of NHFTR efficiently, enhance the quality of transfusion,guarantee the blood transfusion safety.

AIM: To detect the mRNA and protein level of HIF-1 alpha in the tissues of rat's radiated mucosa. METHODS: The left buccal mucosa was irradiated and excised. The right buccal mucosa was excised to serve as own control tissue. The mRNA of HIF-1 alpha was determined by using the semi quantitative RT-PCR. SABC method was employed to immunostain and to elucidate the localization, intensity and distribution of HIF-1 alpha protein.RESULTS: A Sprague-Dawley rat's model of radiation-induced oral mucositis (ROM) was successfully established. The results of RT-PCR indicated that the left buccal mucosa expressed HIF-1 alpha mRNA while the right buccal mucosa did not or seldom expressed it. Immunohistochemical analysis of HIF-1 alpha demonstrated that the left side mucosa expressed HIF-1 alpha protein.CONCLUSION: The mucosa of ROM expresses the mRNA and protein of HIF-1 alpha. The expressions of HIF-1 alpha are correlated with the severity of ROM.

Objective To establish the genetic test technique of trisomy 21 concurrently conducts with prenatal diagnosis for hereditary hearing loss. Methods Fifty-four pregnant women who underwent prenatal diagnosis for hearing loss of their fetuses in Chinese People's Liberation Army General Hospital from March 2009 to May 2010 were enrolled in this study. All probands from the deaf families have confirmed the causative mutation for hearing loss in Genetic Testing Center in Chinese People's Liberation Army General Hospital. The mean age of 54 pregnant women is 31 years at pregnancy of 18 - 26 weeks, 5 cases > pregnancy of 23 weeks, 9 cases ≥ 35 years. All subjects did not conduct the serologic tests for trisomy 21before. Fifteen to twenty ml amniotic fluid was drawn from 49 cases at pregnancy of 18 - 23 weeks and 5 cases > pregnancy of 23 weeks. One to two ml umbilical blood was drawn from 5 cases > pregnancy of 23 weeks. For 9 cases ≥ 35 years, amniotic fluid cell culture and karyotyping analysis were conducted concurrently. A multiple quantitative fluorescent ( QF) PCR and six microsatellite markers were applied to as trisomy 21. Results (1) Fifty-four fetuses were successfully conducted prenatal genetic diagnosis for hearing loss (included GJB2 and SLC26A4). Ten fetuses copied the exactly same genotypes as the probands. The other 44 cases fetuses did not copy the same genotypes as the probands and won't develop hearing loss. The hearing test showed normal hearing for the neonates. (2) All the 54 fetuses were excluded of trisomy 21 by QF-PCR and were verified after birth. Five fetuses with advanced maternal age were performed karyotyping analysis and showed normal. The diagnostic results of QF-PCR can be obtained in 1 - 3 days without misdiagnosed. Conclusions QF-PCR is an efficient, rapid and accurate technique for detection of trisomy 21 without increasing sample amount. It can be used for fetuses who were undertaken hearing loss gene test or other prenatal gene test.
