Objective To observe the protective effect of hydroxysafflor yellow A(HSYA) on anoxia/reoxygenation (A/R) injury of neonatal primary cardiomyocytes, and its relationship with phosphoinositide 3-kinase/protein ki-nase B/glycogen synthase kinase 3β(PI3K/Akt/GSK3β) signaling pathway. Methods Primary cardiomyocytes of neonatal rats were isolated from the rats and incubated for 48 hours. The cells were adhered to each other and then divided into five groups:control group (Con group), anoxia/reoxygenation group (A/R group),HSYA treatment group(A/R+H group),PI3K inhibitor (LY294002)treatment group(A/R+L group)and HSYA+LY294002 treat-ment group (A/R+H+L group),then to collect the supernatant fluid of each group to measure LDH.The flow cy-tometry was used to measure the apoptotic cells. The protein levels of Bcl-2,Bax,Akt,p-Akt (Ser473),GSK3β, p-GSK3β (Ser9) were evalated by Western blot. Results A/R increased LDH release,the apoptosis rate (P<0.001),and the expression of pro-apoptotic protein Bax (P <0.001) with the decrease of anti-apoptotic protein Bcl-2,p-Akt(Ser473), p-GSK3β(Ser9)(P<0.001) as compared with the control group. HSYA treatment de-creased LDH release,the apoptosis rate (P<0.001),and the expression of Bax (P<0.001) and increase the ex-pression of Bcl-2,p-Akt(Ser473),p-GSK3β(Ser9)(P<0.001). Compared with the A/R+H group,the expres-sion of Bax was increased (P<0.001),while the expression of Bcl-2, p-Akt(Ser473), p-GSK3β(Ser9)was de-creased (P<0.001) in the A/R+H+L group. Conclusions HSYA protects rats'cardiomyocytes from anoxia/reoxy-genation injury by regulating PI3K/Akt/GSK3β signaling pathway.

Objective To assess the proficiency of water monitoring laboratory at rural, county, and provincial levels in Guangdong province, to ensure the province's drinking water monitoring results accurate and reliable. Methods State quality of certified reference materials as water arsenic, fluoride and chloride of 90 copies each were numbered and distributed to 90 monitoring laboratories in the province for testing, The measurement results of the participatory labs were evaluated through normative values and expanded uncertainty, and were compared with those of robust statistics method. Results All participatory labs had timely feedback of their measurement results. The qualified rate was higher when arsenic was tested by hydride generation atomic fluorescence spectrometry and zinc-new silver salt of sulfuric acid spectrophotometric system, while fluoride and chloride by ion chromatography. The average qualified rates of water arsenic, fluoride and chloride of the province's rural drinking water quality monitoring laboratory were 66% (59/90), 72% (65/90) and 72% (65/90), respectively.Seven participatory labs failed the proficiency testing of all three analytes and unqualified rate was 7.8% (7/90)among the ninety participated monitoring labs. The qualified rates of robust statistics method for arsenic fluoride and chloride were greater than those evaluated by the expanded uncertainty, and large deviations with small sample sizes. Conclusions The testing ability of drink-water monitoring labs in Guangdong province has improved.However, by comparison with the requirements of national quality control and testing skills, there is still a gap. It is suggested that internal quality control be included in routine inspeetion to improve laboratory testing technology.

OBJECTIVETo analyze the prognostic factors in elderly patients with acute myeloid leukemia (AML).
METHODSThe clinical data of 211 AML patients with age 55 years or over and treated in Shanghai Jiaotong University Medical School affiliated Ruijin Hospital from 2007 to 2011 were collected and analyzed. Multivariate and univariate analysis of clinical data were performed using a Cox regression model and log-rank test, including age, subtype, performance status, white blood cell count, serum LDH and albumin level, and treatment strategy.
RESULTSAcute promyelocytic leukemia (APL) patients had longer survival than other subtypes. To rule out the impact of APL on the prognostic analysis, we conducted multivariate and univariate analysis excluding APL patients. The significant parameters of the univariate analysis were age (P = 0.003), achieving remission (P < 0.01), performance status (P < 0.01), organ dysfunction (P < 0.01), increased WBC counts (P = 0.022), increased LDH level (P = 0.006) and low albumin level (P < 0.01). Multivariate analysis showed that only failure of achieving remission (P < 0.01), poor performance status (ECOG 3-4) (P < 0.01) and increased WBC counts (P < 0.01) were independent prognostic factors. The patients aged 70 years or over had poor overall survival, and no significant difference of OS was observed among patients with age between 55 and 69 years. For patients aged 55 - 69 years received either DA/IA or CAG treatments had longer survival than those with palliative treatments. For those aged 70 years or over, only patients with CAG treatment had significantly longer survival than palliative treatment. For the patients with age less than 70 years and achieving complete remission after induction, intermediate-dose cytarabine consolidation might not improve survival.
CONCLUSIONElderly AML patients should be treated individually. The intermediate-dose cytarabine consolidation might not improve survival of elderly AML patients.

BACKGROUNDPatients with severe full-thickness burn injury suffer from their inability to maintain body temperature through perspiration because the complete destructed sweat glands can not be regenerated. Bone marrow-derived mesenchymal stem cells (BM-MSCs) represent an ideal stem-cell source for cell therapy because of their easy purification and multipotency. In this study, we attempted to induce human BM-MSCs to differentiate into sweat gland cells for sweat gland regeneration through ectodysplasin (EDA) gene transfection.
METHODSThe dynamic expression of EDA and EDA receptor (EDAR) were firstly observed in the sweat gland formation during embryological development. After transfection with EDA expression vector, human BM-MSCs were transplanted into the injured areas of burn animal models. The regeneration of sweat glands was identified by perspiration test and immunohistochemical analysis.
RESULTSEndogenous expression of EDA and EDAR correlated with sweat gland development in human fetal skin. After EDA transfection, BM-MSC acquired a sweat-gland-cell phenotype, evidenced by their expression of sweat gland markers by flow cytometry analysis. Immunohistochemical staining revealed a markedly contribution of EDA-transfected BM-MSCs to the regeneration of sweat glands in the scalded paws. Positive rate for perspiration test for the paws treated with EDA-transfected BM-MSCs was significantly higher than those treated with BM-MSCs or EDA expression vector (P < 0.05).
CONCLUSIONSOur results confirmed the important role of EDA in the development of sweat gland. BM-MSCs transfected with EDA significantly improved the sweat-gland regeneration. This study suggests the potential application of EDA-modified MSCs for the repair and regeneration of injured skin and its appendages.

Human xanthine oxidase is considered to be a target for therapy of hyperuricemia. Cichorium intybus is a Chinese plant medicine which widely used in Xinjiang against various diseases. In order to screen the inhibitors of xanthine oxidase from C. intybus and to explore main pharmacological actions of cichory a compound collection of C. intybus was built via consulting related references about chemical research on cichory. The three-dimensional crystal structure of xanthine oxidase (PDB code: 1N5X) from Protein Data Bank was downloaded.. Autodock 4.2 was employed to screen the inhibitors of xanthine oxidase from cichory 70 compounds were found to possess quite low binding free energy comparing with TEI (febuxostat). C. intybus contains constituents possessing potential inhibitive activity against xanthine oxidase. It can explain the main pharmacological actions of cichory which can significantly lower the level of serum uric acid.

Objective To study the influence of CYP3A5 genetic polymorphism on tacrolimus metabolism in renal transplantation recipients and evaluate the methods of detecting CYP3A5* 3 polymorphism. Methods Ninety-seven renal recipients receiving the triple immunosuppressive (tacrolimus + mycophenolate mofetil + prednison) were genotyped for CYP3A5* 3 polymorphisms by the Pyrosequencing TM assays. Tacrolimus trough concentration of the patients was measured by enzyme multiplied immunoassay technique, and concentration/adjusted dose ratio (C/D) was investigated at the 7th day, 14th day, 1st month, 3rd month and 6th month after renal transplantation. Results The Pyrosequencing TM assays allowed for quick and accurate detection of CYP3A5* 3 genotypes. There were CYP3A5* 1/* 1 genotype in 17 cases (17. 5%), * 1/* 3 in 35cases (36. 1 %) and *3/* 3 in 45 cases (46.4 %) identified in 97 renal recipients. The C/D of CYP3A5 * 1/* 1 and * 1/* 3 patients was significantly lower than that of * 3/* 3 patients (P<0. 01)after renal transplantation. Conclusion The CYP3A5* 3 polymorphisms are significantly correlated with tacrolimus pharmacokinetic in renal transplant recipients. Detecting the CYP3AS* 3 genotype of the recipient before the transplantation by the Pyrosequencing TM assays can be used to help determine the optimal initial dosage after transplantation, resulting in individualized drug therapy.

The auricular (including auricular acupoints) adjuvant diagnostic method, besides inspection (including dyeing method), palpation (including thermometric method), tenderness method (including impressing method) and electrical detection, includes the adjuvant diagnostic method of stimulating auricular points as well, it has been mostly studied and used by specialists of western medicine or doctors of integrated Chinese and western medicine. But it hasn't been introduced in the published Chinese monographs of auricular acupuncture yet. This article briefly introduces the adjuvant diagnostic method of stimulating auricular points combined with X-ray radiography; application in fetal heart electronic monitoring and fetal biophysical monitoring; and diagnostic methods of auricle reflex, vascular autonomous signals, and auricle and somatic 7 frequency response regions, which began to be researched abroad 35 years ago. The authors hope it will give some invigoration or illumination to my colleagues in acupuncture, especially those who are interested in auricular acupuncture.
