Objective To evaluate the accuracy of ultrasonography and magnetic resonance imaging detection on preoperatively predicting axillary lymph node in breast cancer patients.Methods From August 2010 to February 2011,the clinical data of 293 breast cancer patients underwent preoperative breast ultrasound exam and MRI detection in Ruijin Hospital were analyzed retrospectively.Results In 293 breast cancer patients,3 suffered from bilateral breast cancer.The sensitivity,specificity,negative predictive value and positive predictive value of ultrasound were 60.0％,90.6％,78.0％ and 80.2％,respectively.The sensitivity,specificity,negative predictive value and positive predictive value of MRI test were 50.5％,90.8％,74.0％ and 77.9％,respectively.There was no significant difference between ultrasound and MRI test in these four indices (P ＞ 0.05).No significant difference on accuracy and predictive value was seen in subgroup analysis according to tumor size,tumor grade,hormone receptor and HER2 status between the two examinations.The sensitivity and specificity of ultrasound associated with MRI test were 70.6％ and 97.2％.Conclusions The accuracy and predictive value between preoperative ultrasound exam and MRI is comparable.Ultrasound associated with MRI examination can achieve high specificity,which may spare a portion of patients free from sentinel lymph nodes biopsy.

Objective To assess the latency and amplitude changes in P300 in senile patients with depression.Methods 13 domestic published study literatures meeting our criteria were searched from CBM,CNKI,and a meta-analysis on P300 latency and amplitude was performed with RenMan 4.1 soft ware.Results 1.The P300 latency in senile patients with depression was significant longer than that in senile normal controls in N1,P2,N2,P300 (N1:WMD=3.07,95 ％ CI:0.7～5.42,Z=2.55,P=0.010;P2:WMD=18.41,95％CI:15.11～21.71,Z=10.93,P＜ 0.01;N2:WMD=25.41,95％CI:12.80～29.02,Z=13.80,P＜0.01;P3:WMD=32.14,95％CI:24.14～34.88,Z=23.04,P＜0.01).2.The amplitude in senile patients with depression was significant lower than that in senile normal controls in N2,P2,P3 (P2:WMD=-0.83,95％CI:-1.07～-0.59,Z-6.78,P＜0.01; N2:WMD＝-0.34,95％CI:-0.59～-0.08,Z=2.57,P=0.01;P3:WMD=-2.54,95％CI:-2.75～-2.33,Z=23.99,P＜0.010).Conclusions P300 longer latency and lower amplitude are the statistically characterized features for senile depressive patients.

Objective To explore the role of monitoring the cellular immune function in preventing and treating the fungal infection in the recipients of liver transplantation. Methods 679 cadaveric liver transplantations (from Jan. 2004 to Jan. 2010) were retrospectively studied. All the cases were divided into 3 groups according to different treatments and preventing regimens. The patients in groups A, B, C were treated based on the clinical experiences (394 cases), T lymphocyte subsets counting (151 cases), and combination of ATP values of CD4+ T cell and T lymphocyte subsets counting (134 cases), respectively. The infection, mortality and acute rejection rate were analyzed. The relationship between fungal infection and cellular immune function was investigated.Results The fungal infection rate in groups A, B, and C was 28. 9 %, 21.2 %, and 19. 4 % (P<0. 05), the morbidity rate was 16. 7 %, 12. 5%, and 3. 8% (P>0. 05), and the acute rejection rate was 28. 4 %, 17. 2 %, and 13. 4 % (P<0. 01), respectively. The CD4+ T lymphocyte counting in all cases of fungal infection was (147±43)×106/L. The morbidity could reach 50. 0 % when the CD4+ T lymphocyte counting < 100 ×106/L, while it was 2. 4 % when the counting was between (100-200) ×106/L (P<0. 01). The CD4+ T lymphocyte counting had no linear relation with the ATP value.The ATP value in fungal infection cases was (117 ± 61)μg/L. Conclusion The cellular immune function test could be quantitatively evaluated according to the T lymphocyte subsets and ATP value of CD4+ T lymphocyte. And individualized immunosuppressive therapy could be adjusted accordingly.Therefore, cellular immune function could be instructive in preventing and treating the fungal infection after liver transplantation.

Objective To explore the monitoring and the individualized adjustment of cellular immunology function in the recipients infected with pan-drug resistant Acinetobacter baumannii(PDR-Ab)after liver transplantation.Methods We retrospectively summarized the infection and the prognosis of PDR-Ab in 299 cases of liver transplantation performed from Jan.2008 to May 2010.The absolute number of T lymphocytes and ATP level within CD4+ T cells were monitored,and T cell immunology function(TCIFS)was scored.According to different immunology adjusting proposals,14 cases of PDR-Ab infection were divided into 2 groups:(1)traditional group,routine anti-infective therapy;(2)individualized group.Individualized immunology adjustment was made according to the score of TCIFS besides routine therapy.Results There was no significant difference in age,MELD and Child-pugh score between two groups.The peri-operative bleeding volume in individualized group was more than that in traditional group(P<0.01).There was no significant difference in TCIFS score between two groups at 1st week after transplantation and the onset of the PDR-Ab infection.However,the score in individualized group was apparently higher than that in traditional group when anti-infection therapy ended(P<0.05).The difference in the recovery rate between two groups was significant(P<0.05).No rejection happened in two groups.Conclusion It is an effective way to decrease the mortality of PDR-Ab infection after liver transplantation that the individualized adjustment of immunosuppression protocols is guided by grading quantitatively the cellular immunology function according to the absolute number of T lymphocytes and ATP level within CD4+ T cells.

Objective To explore the relationship between ATP content in CD4+ T lymphocytes and acute rejection after liver transplantation(LT). Methods This study contained 77 patients who received LT from February to October 2009, They were divided into AR (acute rejection) and NAR (non-acute rejection) groups while 56 healthy people were enrolled to serve as the control group.Blood specimens were collected preoperatively and at 1, 2 and 4 weeks postoperatively. For the AR group, specimens were also collected on the day when AR occurred and 1 week after steroid bump together with that of the healthy people. ImmuKnowTM test kits for immune cell function were used to assay the ATP value. Results ATP values within CD4+T lymphocytes were elevated significantly in each group compared with those preoperatively. Peak level was reached in the AR group and was significantly higher than that of the contemporary NAR group (P＜0.05). ROC curve analysis showed that the obvious elevation of the ATP value within CD4+ T lymphocytes 1 week postoperatively had better sensitivity and specificity in diagnosing AR. The ATP sensitivity rate for early AR was 84.6 %and specificity rate 81 %. The ATP value within CD4+ T lymphocytes on the day of AR occurrence had a positive relationship with the rejection acting index(RAI), while relative index (r) was 0. 876(P＜0.05). After the steroid dump treatment, AR in all the patients was reversed and the ATP value declined significantly as compared with the control group and the day when AR occurred(P＜0. 05).Conclusion During the postoperative period, the dynamic change of ATP value within CD4 + T lymphocyte had a close relationship with acute rejection after liver transplantation. Thus, it might be used as a feasible and noninvasive monitoring index for diagnosing AR and the effectiveness of the anti-rejection treatment.
