2.Report on recent insight into molecular genetic alterations and target therapy in T-cell acute lymphoblastic leukemia in the 54th ASH annual meeting
Journal of Leukemia & Lymphoma 2013;22(1):1-3,7
T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy associated with poor prognosis.Increasing data regarding to alteration of gene expression signatures of oncogenes and tumor suppressors involved in the pathogenesis of T-ALL and the major mechanisms of T-cell transformation may contribute to define the biological markers for treatment response and prognosis,and has important clinical implications.In this review,advance knowledge concerning the characteristics of early T-cell precursor ALL,the alteration of TAL1 and NOTCH1 related genes and target inhibiton effects based on these alterations from 2012 the 54th ASH annual meeting ars summarized.
5.Relationship between serum elevation of N-terminal pro-brain natriuretic peptide and malnutrition in very old male patients with normal ejection fraction
Chinese Journal of Geriatrics 2015;34(1):3-7
Objective To investigate the association between malnutrition parameters and serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level in male patients aged ≥ 80 years with normal ejection fraction.Methods A total of 197 elderly male patients aged 80 95 years (average 85.4±9.7) were enrolled.Each patient received echocardiograms following admission,and ejection fraction was calculated.Serum concentrations of NT-proBNP were measured by electrochemiluminescence immunoassay.Multiple Logistic regression analyses and receiver operating characteristic (ROC) curves were used to assess the association between malnutrition parameters and serum level of NT-proBNP.Results Serum NT-proBNP level was higher in patients with malnutrition than in the controls [(711.9±1063.3) ng/L vs.(1375.2-±1891.7) ng/L,P=0.006].Pearson correlation analysis showed that the malnutrition parameters such as body mass index (BMI),blood hemoglobin,albumin and pre-albumin were negatively correlated with serum NT proBNP level (all P<0.05).Logistic regression analysis showed that BMI and serum pre albumin level were independently associated with serum NT-proBNP level elevation (P=0.028 and 0.006,respectively).ROC curve analysis showed that the malnutrition parameters could predict the serum NT-proBNP level elevation.The area under the ROC curves for BMI,levels of blood hemoglobin,albumin and prealbumin in predicting serum NT proBNP level elevation was 0.7 (P=0.002),0.7 (P=0.004),0.6 (P=0.036),0.6 P=0.002),the sensitivity was 75.5%,51.0%,38.8%,89.8%,and the specificity was 54.4%,70.2 %,84.2% and 31.6 %,respectively.Conclusions The malnutrition parameters including BMI,blood hemoglobin,albumin and pre-albumin can predict serum NT-proBNP level elevation.BMI and serum pre-albumin level are independently associated with serum NT-proBNP level elevation in male patients aged ≥ 80 years with normal ejection fraction.

Objective To reconstruct the soft tissue defect in the back or neck after excision of hypertrophoc scar or giant nevus by using transmidline pre expanding scapula flap vascularied by ipsilateral circumflex scapular artery. Methods The reconstruction can be accomplished in two stage procedures. First, scapular flaps were expanded for 4 6 weeks prior to transfer in 8 patients. Second,the pedicled flaps were designed across the entire back to incorporate both scapular territories but were rotated on a single vascular pedicle. Results All flaps survived. Only two flaps had marginal necrosis, and the wound healed well by dressing. Conclusion Flap expansion produces a delay that augments blood supply and increases the area of skin that survives on a single vascular pedicle. This technique may be useful in selected patients in whom a large and thin fasciocutaneous flap is required and there is sufficient time to allow flap expansion prior to thansfer. It is easy to harvest, and donor site morbidity is negligible. The patients can get better functions and quality of life.

The donated organ after cardiac death would undergo warn ischemia injury inevitably,and the incidences of primary non-function of donated organs,transplanted organ loss and ischemic-type biliary lesions were increased.It is a paramount research dilemma to devise how to avert,lessen and recover the warm ischemia organs after donation of cardiac death (DCD).Since February 2009,the Liver Transplantation Center of Guangzhou General Hospital of Guangzhou Military Command of PLA has applied the extracorporeal membrane oxygenation (ECMO) to protect the organs of DCD.The mechanism of recovering the donors from warm ishemia by ECMO has good prospects in the field of international organ donation,and it is an important method to solve the problem of donor shortage in China.Spreading the application range of ECMO in DCD and establishing the standard procedures and techniques in China is of great importance.

Objective To compare the different effects of two rehabilitative therapies on cardiac rehabilitation of patients with acute myocardial infarction after interventional program.Methods Eighty AMI patients with no complications after interventional treatment were randomized equally into the observation group and the control group.The patients in the control group were given two-week cardiac rehabilitative training in line with the clinical nursing pathway.Besides the treatment in the control group,those in the observation group were given 10-day cardiac rehabilitative training by optimizing the nursing pathway.The two groups were compared in terms of left ventricular ejection fraction,self-care ability,heart function grading,incidence of complications,hospital stay and hospitalization cost.Results At discharge,The observation group was significantly better than the control group in terms of left ventricular ejection fraction,self-care ability and grading of cardiac function(all P<0.05).In regard to the incidence of complications,there was no statistically significant difference between the groups.Hospital stay in the observation group was obviously shorter than that in the control group and the hospitalization cost significantly less than that in the control group(P<0.01).Conclusion The 10-day cardiac rehabilitation program can promote patients’recovery,shorten the hospital stay and reduce the medical expense.
9.Analysis of the Puzzle between Acupuncture Community and Acupuncture Clinical Trials.
Chinese Journal of Integrated Traditional and Western Medicine 2016;36(3):261-265
Recently a number of acupuncture clinical trial projects mainly conducted by conventional scientists have generated many negative results. A large meta-analysis of patient-level acupuncture data for the treatment of chronic pain conditions have demonstrated that the effects of verum acupuncture on pain improvement have statistically significant, but small, differences compared with sham-acupuncture procedures and no difference between acupuncture points and non-points. These conclusions have puzzled the acupuncture community and made confusion for acupuncture research and practices. The purpose of this paper was to compare differences between acupuncture clinical practices and the trial studies, which include "acupuncture technical principles", "acupuncture clinical trial design", and "acupuncture practice based on the theory of traditional Chinese medicine". These factors contribute to the puzzle between the acupuncture community/practice and acupuncture clinical trials, which can be improved in future studies.
