Minimal residual disease (MRD) is one of the important variables to evaluate the outcomes of patients with leukemia, which is related to the relapse and survival of patients after treatment. This article summarizes the new progress on diagnosis and treatment of leukemia from the perspective of MRD in combination with some representative studies on MRD-based prognostic assessment and guidance on treatment options that were reported at the 62nd American Society of Hematology (ASH) Annual Meeting.

150 ml in 22 patients (31%).Ten patients (14%) had detru-sor instability.Six patients were incapable to void during the test. The volume of first bladder sensation was(203.25?107.53)ml (range,125 -630 ml) in the diabetes patients.The bladder capacity was (428.09?227.89)ml (range,220 -1350 ml).The maximum flow rate was (10.70?3.27) ml/min.The residualurine volume was (100.57?108.08) ml.In early stage group the volume of first bladder sensation was(151.67?24.07) ml;while in progressive stage group it was (268.16?13.90)ml,and bladder capacitywas (592.97?252.51)ml.The maximum flow rate was (8.61?2.04) ml/min. PQmax was (33.16?19.81)cm H2O (1 cm H2O=0.098 kPa).The residual urine volume was (169.03?137.25) ml. Theseparameters were all abnormal. In the detrusor strips test,the threshold of the tension which made the detrusorstrips contract was significantly higher in T2DM rats [(0.72?0.33) g] than in control rats [(0.32?0.18)g] (F=59.63,P

Objective To investigate the epidemiology of drug-resistant tuberculosis (TB) in five rural counties of eastern China and analyze the biological,demographic and social risk factors.Methods Subjects of this study were all the diagnosed TB patients registered in the five study sites in Shandong Province,Jiangsu Province and Zhejiang Province during one year of 2008- 2009.Questionnaire interview was conducted in all the subjects to acquire the socio-demographic and clinical information.Sputum samples were collected for culturing and isolating of Mycobacterium tuberculosis (M.TB) strains.All the M.TB isolates were further tested for the susceptibility to first-line drugs including rifampin,isoniazid,ethambutol and strepomycin by proportion method.Mantel-Haenszel chi-square test,Fisher's exact test,ANOVA and nonconditional Logistic regression modeling were applied for data analysis.Results Among the total 380 M.TB isolates,105 were resistant to at least one of the first-line drugs.The total drug resistant TB prevalence was 27.6％.Multidrug-resistant tuberculosis (MDR-TB) was observed in 8.4％ of newly treated TB patients,whereas it was 23.3％in previously treated TB patients.After adjusted by county,gender and age of the subjects,multivariate analysis showed that previous treatment history (OR=3.900,95％CI: 1.737-8.704),tuberculosis cavity (OR - 1.987,95 ％ CI: 1.001 - 3.942) were independent factors influencing the occurrence of MDR-TB.Conclusions The prevalence of drug resistant TB in rural area of eastern China is relatively low compared with the average level in China,while it is still higher than the global average level.The present study highlights that TB patients with previous treatment history,cavitaryTB are correlated with MDR-TB,and elderly patients are at high risk of MDR-TB.

Objective To evaluate the safety and feasibility of totally thoracoscopic anatomic pulmonary segmentectomy (TTAS) for the treatment of the peripheral stage ⅠA non small cell lung cancer(NSCLC).Methods The study involved 50 consecutive patients undergoing totally thoracoscopic anatomic segmentectomy (TTAS) from September 2010 to November 2012 in the First People's Hospital affiliatied to Nanjing Medical University.The diameter of the tumors were less than 2 cm [(mean diameter(1.35 ±0.48) cm].All lymph node sampling of N1 and N2 were neglive,All patients received symtematic lymph node dissection.The pulmonary vessels were individually ligated,and the bronchi were closed using an endoscopic stapler.The intersegmental plane was identified using the demarcation between the resected(inflated) and preserved(collapsed) lungs.Staplers were used for intersegmental dissection.Results The mean operative time and intraoperative bleeding were (191.5 ± 50.4) min and (49.2 ± 54.6) ml respectively.The chest tube drainage duration was (3 ± 1) days.The number of stapler cartridges used for intersegmental division was 3.9 ±0.8.The mean number of lymph nodes and nodal stations dissected were 12.6 ± 2.8 and 6.0 ± 1.5 respectively.No mortality and complications were observed 30 days after the surgery.Further,no local recurrence or metastases were observed during follow-up.Conclusion Totally thoracoscopic anatomic segmentectomy(TTAS) is a feasible and safe technique.With systematic lymph node dissection,TTAS can be a reasonable therapeutic option for stage ⅠA NSCLC.

The changes in excitability and autorhthmicity of bladder detrusor in experimental non-insulin dependent diabetes mellitus (NIDDM) rats were observed. Sixty-nine NIDDM rats as NIDDM group and 69 normal rats as control group were enrolled into this experimental study. At 6th, 10th, 14th, 18th, 22nd and 26th week after the rats were injected last time, the changes in the excitability and autorhthmicity of detrusor strips in vitro were observed. The results showed that the threshold of the tension which made the detrusor strips contract was significantly higher in NIDDM group (0.716 +/- 0.325 g) than in control group (0.323 +/- 0.177 g) (F = 59.63, P < 0.001). At different stages, the threshold of the tension resulting the contract of the detrusor strips in NIDDM group was also higher than in control group. At 18th week after STZ injection, the frequency of spontaneous contract of the detrusor strips in NIDDM was significantly higher than in control group (P < 0.05), whereas at 22nd week, that in NIDDM group was significantly lower than in control group (P < 0.05). It was concluded that the decreased excitability of the bladder detrusor was the earliest and most obvious changes in bladder function in diabetes rats and the autorhthmicity had also changed at the early stage of diabetic bladder.
