1.Progress in preconditioning regimen of autologous hematopoietic stem cell transplantation for treatment of multiple myeloma
Journal of Leukemia & Lymphoma 2017;26(5):313-317
High-dose melphalan (Mel) is considered as a current standard preparative regimen in autologous stem cell transplantation (ASCT) for multiple myeloma (MM). Irradiation in total body (TBI) combined with Mel is not superior to Mel alone, and the adverse reactions are increased at the same time. The efficacy of 200 mg/m2 Mel is much better than that of 100-140 mg/m2 Mel in young patients. Several regimens including MelBU, TBC, BCV, MET, MTC, MelBCNU, VMel, MTC as well as bendamustine have similar treatment outcomes compared with 200 mg/m2 Mel. Other strategies need to be evaluated in different trials.

Chinese Journal of Primary Medicine and Pharmacy 2013;20(15):2319-2321
Objective To observe the effect of levocamitine on cardiac function of patients with dilated cardiomyopathy (DCM).Methods 40 patients with DCM were randomly divided into control group (n =20) and the experimental group(20 cases).Control group was given conventional drug such as digitalis,furosemide,benazepril hydrochloride,antisterone for treatment,the experimental group was given levocarnitine on the basis of control group.The treatment efficacy and the situation of cardiac function were compared between the two groups.Results The total effective rate was 95.0% and 80.0% in the experimental group and the control group,respectively,the difference was statistically significant(x2 =10.286,P < 0.01).Compared with the control group,the parameters of stroke volume,cardiac output,ejection fraction,and left ventricular fractional shortening rate were significantly increased in the experimental group after treatment(all P < 0.05).Conclusion Levocarnitine can improve cardiac function based on the conventional treatment.
3.Serum p2PSA derivative indexes in prostate cancer: an update.
National Journal of Andrology 2015;21(1):74-77
Serum prostate-specific antigen (PSA) is composed of the PSA precursor protein (proPSA) in the absence of the leader peptide induced by human kallikrein 2 (hK2). There are many forms of PSA in the blood, including free PSA and bound PSA. Serum proPSA, as a free PSA, has many isoforms, among which, [-2]proPSA (p2PSA) cannot be activated by hK2 and therefore exists stably in the blood. Serum p2PSA is a homologous isomer of PSA. Serum prostate health index and % p2PSA, as the derivative indexes of p2PSA and molecular markers associated with the development and progression of prostate cancer, can reduce serum PSA test-induced excessive diagnosis and treatment of the malignancy and improve the accuracy of its prediction. This review summarizes recent progress in the studies of serum p2PSA and its derivative indexes in prostate cancer.

5.Efficient iris recognition via ICA feature and SVM classifier
Journal of Pharmaceutical Analysis 2007;19(1):29-33
To improve flexibility and reliability of iris recognition algorithm while keeping iris recognition success rate, an iris recognition approach for combining SVM with ICA feature extraction model is presented. SVM is a kind of classifier which has demonstrated high generalization capabilities in the object recognition problem. And ICA is a feature extraction technique which can be considered a generalization of principal component analysis. In this paper, ICA is used to generate a set of subsequences of feature vectors for iris feature extraction. Then each subsequence is classified using support vector machine sequence kernels. Experiments are made on CASIA iris database, the result indicates combination of SVM and ICA can improve iris recognition flexibility and reliability while keeping recognition success rate.
6.The comparison of diagnostic value of FNAB and CNB in the treatment of patients with invasive breast cancer
International Journal of Laboratory Medicine 2017;38(17):2421-2423
Objective To investigate and compare the diagnostic value of fine needle aspiration biopsy(FNAB) and core needle biopsy(CNB) in the treatment of patients with invasive breast cancer.Methods Given 100 cases of patients with newly diagnosed breast cancer biopsy in our hospital from November 2015 to November 2016,50 cases of patients with FNAB into the observation group,50 cases of patients with CNB into the control group.Taken the pathologic results as a diagnostic gold standard and compared the diagnostic value of two diagnostic methods in invasive breast cancer.Detected the human epidermal growth factor receptor 2(Her-2),estrogen receptor(ER) and progesterone receptor(PR) preoperatively and compared the adverse reactions of puncture of patients in two groups.Results 30 cases of patients in the observation group showed axillary lymph node metastasis and 20 cases of patients had no axillary lymph node metastasis,21 cases of patients were positive cases of axillary lymph node metastasis accepted FNAB examination,the sensibility was 70.00%.29 cases of patients in the control group showed axillary lymph node metastasis while 21 cases of patients didn′t have axillary lymph node metastasis,23 cases of patients were positive cases of axillary lymph node metastasis accepted FNAB examination,the sensibility was 74.19%.Compared the ER、PR、Her-2 antibody with the testing result of primary tumor after operation.The diagnostic accordance rates in the observation group were 93.55%,91.67%,92.86% respectively.The diagnostic accordance rates in the control group were 94.12%,92.31%,86.67%,the differences in two groups were not statistical significance(P>0.05).The adverse reaction rate was 4.00% in the observation group and 0.00% in the control group after puncture.Conclusion The diagnostic sensibility of FNAB is poorer than CNB in the diagnostic procedure of invasive breast cancer.ER,PR,Her-2 in two diagnostic methods keep a high consistency with the testing result of primary tumor after operation.
7.The economic effects of rural residents' health in China: Empirical analysis based on endogeneity
Chinese Journal of Health Policy 2017;10(4):71-76
As a sort of human capital, health is a concrete manifestation of human productivity.At home and abroad, there are many empirical studies focusing on the economic effects of health that have been conducted, but the research methods have not paid enough attention to the endogeneity of health in those studies.This paper evaluates the effects of health on the income of rural residents in China with the micro panel data from China Health and Nutrition Survey.To get reliable results, the paper controls the endogenity of health by using simultaneous equation model and solves the parameters by using the three-stage least squares method.The study found that health has significantly positive effects on the income of rural residents in China, a conclusion which is in conformity with the economic effects of health.To improve the health of rural residents and fully implement the economic effects of health, the study recommends the government to put more efforts on promoting healthcare services, health-related education, and improving the living standards of rural residents in China.

9.Prevention and treatment of nephrotic syndrome associated bone metabolic abnormality in children
Chinese Journal of Applied Clinical Pediatrics 2015;30(17):1358-1360
Metabolic bone disease in nephrotic syndrome(NS) are increasingly being renal physician's attention.As calcium binding protein and VitD binding protein losing with a large number of protenuria, the bone metabolic biochemical abnormalities had happened at the beginning of the onset of the nephrotic syndrome, and is further exacerbated by therapeutic high-dose or long course of glucocorticoids (GC) application.The main mechanism of the glucocorticoid-induced osteoporosis (GIOP) is for GC to inhibit the activity of osteoblasts and promote apoptosis of osteoblasts and formation of osteoclasts, resulting in secondary hyperparathyroidism,leading to increasing the risk of osteoporosis,slow growth and fracture,seriously harm to children's physical and mental health.The biomarkers of bone transform can prompt the NS with bone metabolic abnormalities early;vertebral body bone dual-energy X-ray absorptiometry bone mineral density detection is the best method and position to determine GIOP.As the most commonly used and effective means to prevent and control metabolic bone disease, calcium supplements and VitD were always taken when GC was treated for NS, even the dosage of GC was very low.So far, it is still lack of guideline of prevention and treatment of bone metabolic abnormalities in NS in children.
10.Variability and clinical application of metabolic markers of bone
Tianjin Medical Journal 2015;(2):221-224
Metabolic markers were released in the process of bone resorption and formation during bone remodelling. These markers have been extensively studied in trials of osteoporosis and other metabolic bone disorders during the past de?cades. Bone metabolic markers can replenish bone mineral density in the management of osteoporosis, but their use in clini?cal practice is challenged by their variability. Recently, there are many great progress in research of bone metabolic markers application in non metabolic bone disorders.
