BACKGROUND: Chronic myeloid leukemia (CML) is characterized by the clonal expansion of hematopoietic stem cells. Without effective treat ment, individuals in the indolent, chronic phase (CP) of CML will undergo blast crisis (BC), the prognosis for which is poor. Therefore, it is important to clarify the mechanism underlying CML from a whole-genome perspec tive. OBJECTIVE: To investigate the gene expression profile of bone marrow mononuclear cells from CML with Applied Biosystems Expression Array System.DESIGN: Observation and controlled analysis.SETTING: Institute of Gene Engineering, Southern Medical University PARTICIPANTS: Samples of two cases of bone marrow (a chronic myeloid leukemia patient and a healthy person).METHODS: This experiment was conducted at the Institute of Gene Engineering, Southern Medical University from October 2004 to September 2005.The total RNAs were extracted and purified from bone marrow mononuclear cells derived from a CML patient and a healthy person. mRNAs were purified using an oligo (dT)-cellulose mRNA purification kits and labeled using reverse transcription, in vitro transcription (RT-IVT), then hybridized with microarray. Gene expression differentiation of the bone marrow mononuclear cells were examined by ABI 1700 Chemiluminescent Microarray Analyzer. Reproducibility of microarray results was assessed by comparing data sets obtained from the same sample and analyzed by two different arrays.MAIN OUTCOME MEASURES: ①Assessment of quality of total RNA and labled cRNA. ②Reproducibility of microarray. ③ Hybridization of array.④Results of semi-quantitative reverse transcription-polymerase chain reaction RESULTS: ①Using statistical data analysis tools, we identified 6 706 genes that were up- or down-regulated in CML patient compared with the healthy person. In these genes, we found that 17 genes were up-regulated while 51 genes were down-regulated among 68 genes closely related to CML. ②most differentially expressed genes in C/EBPalpha mediated path way and CD40L signaling pathway had reduced expression. ③Good repro ducibility of microarray was confirmed by analysis of correlation and detection concordance in technical replicates. The correlation coefficient of the detectable probe in technical replicates was 0.991 for the CML patient and 0.988 for the healthy person. ④The results of semi-quantitative RT-PCR experiments supported the reliability of our microarray analysis.CONCLUSION: By comparing expression patterns of CML with those of the healthy person, we identified a large number of genes that, were up- or down-regulated in CML patients. These data should provide useful information for finding candidate genes whose products might serve as molecular targets for treatment of CML patients.

Objective To summarize the successful experience of three cases of heart-lung transplantations performed in our institute.Methods From July 2003 to August 2012,three patients,with diagnosis of end-stage heart-lung diseases,received heart-lung transplantation in our institute.One case was diagnosed as congenital atrial septal defect,Eisenmanger syndrome,NYHA class Ⅳ; one was dilated cardiomyopathy with moderate/severe pulmonary arterial hypertension,NYHA class Ⅲ-Ⅳ,one was diagnosed as double outlet left ventricle (DOLV) with ventricle septal defect and stenosis of pulmonary artery and its left and right branches,NYHA class Ⅲ-Ⅳ.Donor hearts were preserved with UW solution,donor lungs were preserved with Euro-Collin solution in case one and with low potassium dextran containing prostaglandin E1 in the others.Extensive disinfection and strict scrutiny were implemented postoperatively.Immunosuppressive therapy included administration of zenapax or basiliximab preoperatively,methylprednisolone during the operation,and cyclosporine a/tacrolimus + prednisone + mycophenolate postoperatively.Surgical hemostasis is of great importance,as the total pleural effusion reaches 14 640 ml within 31 days postoperatively in case two.Strict postoperative disinfection and isolation were implemented,and management of the respiratory tract was intensified.Therapeutic bronchoscopy was performed frequently for sputum suction.In case two,bronchoscopy was used thirteen times within 40 days after transplantation.Broad-spectrum antibiotics and antifungal antibiotics were used for infection control.Results All three patients were discharged after recovery from operation.Case one died of obstructive bronchitis and lung failure caused by chronic rejection four years and ten months postoperatively.Case two died of sudden cerebrovascular accident 68 days after operation.Case three survives more than one year postoperatively so far and is still alive.Conclusion Proper preservation of the donor heart and lung,perfect surgical hemostasis,strict infection control,frequent application of bronchoscopy and appropriate immunosuppressive management are critical to the success of heart-lung transplantation.

Objective To investigate the effects of maternal long-term exposure to low-dose trichlorfon on the serum paraoxonase (PON) activity of pregnant mice and development of embryos. Methods Female ICR mice (n=120) were randomly divided into control group and trichlorfon groups of different doses,and were managed by intragastric injection with trichlorfon of 0,2,10 and 50mg/kg,respectively. All the mice were managed once a day for a consecutive of 27 days,and were subjected to mating. The pregnant mice were continued to be managed with trichlorfon for 3 days,and were sacrificed on day 3 of gestation. The serum PON and acetylcholinesterase (AchE) activities were detected,and the development of embryos was evaluated. Results The serum PON activity of 2,10 and 50mg/kg trichlorfon group were (14.15?1.22),(12.78?1.80) and (10.45?1.95)IU/mL,respectively,and that of 50mg/kg trichlorfon group was significantly lower than that of control group [(13.37?2.31)IU/mL] (P0.05),while the the percentage of abnormal embryos of 50mg/kg trichlorfon group had an increased tendency. Conclusion Long-term exposure to low-dose trichlorfon can inhibit serum PON and AchE activity in pregnant mice without obvious effect on the development of embryos.

Objective To report a new method of fluorescent labeling technique in microarray studies: universal primer U2 labeling( UPL). The efficiency was compared of the UPL with that of random primer, restriction display labeling method and the reverse transcription coupled random primer spiking labeling method(RT-PSL). Methods Influenza viral RNA was labeled with both UPL and the conventional random primer labeling method as well as two other more laborious labeling methods( RD-direct and RD-incorporate), and hybridized with influenza virus oligonucleotide microarrays. The signals extracted from the microarrays were analyzed using SPSS 10.0 software. Results The fluorescent intensity, signal-to-noise ration(SNR), true positive ratio(TPR) of probes and labeling reproducibility of UPL were demonstrated to be higher than those of the Random primer approaches.Conclusion These results established that UPL is a valid new labeling protocol, which may have wide applications in the research and development of the microarray technology.

BACKGROUNDPolypharmacy and potentially inappropriate medications (PIMs) are prominent prescribing issues in elderly patients. This study was to investigate the different prevalence of PIM use in elderly inpatients between 65-79 years of age and 80 years or older, who were discharged from Geriatric Department in West China Hospital.

METHODSA large-scale cohort of 1796 inpatients aged 65 years or over was recruited. Respectively, 618 patients were 65-79 years and 1178 patients were 80 years or older. Updated 2012 Beers Criteria by the American Geriatric Society was applied to assess the use of PIM among the investigated samples.

RESULTSA review of the prescribed medications identified 686 patients aged 80 years or older consumed at least one PIM giving a rate of 58.2%. Conversely, 268 (43.4%) patients aged 65-79 years consumed at least one PIM (χ2 = 40.18, P < 0.001). Patients aged 80 years or older had higher hospitalization expenses, length of stay, co-morbidities, medical prescription, and mortality than patients aged 65-79 years (all with P < 0.001). Patients aged 80 years or older were prescribed with more benzodiazepines, drugs with strong anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin. In multiple regression analysis, PIM use was significantly associated with female gender, age, number of diagnostic disease, and number of prescribed medication.

CONCLUSIONSThe finding from this study revealed that inpatients aged 80 years or older encountered more PIM use than those aged 65-79 years. Anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin are medications that often prescribed to inpatients aged 80 years or older. Doctors should carefully choose drugs for the elderly, especially the elderly aged 80 years or older.

Objective To observe the state of endemic flurosis, construction and running status of water improvement projects in order to provide a scientific basis for prevention and treatment fluorosis. Methods Water samples of the diseased and nondiseased villeges were collected from east, west, south, north and centre of each villege in 2005, and fluoride concentration was determined for each surveyed village with unimproved-water. At the same time, all the tap water and source water samples were collected to determine fluoride concentration in each water-improved village surveyed. In 2008, all the endemic fluorosis villages in Guied county were divided into slight, medium and heavy types according to the water fluoride content before water improved, and 1,1,3 survey villages were chosen from each type. In all of the village children aged 8 to 12 years were tested for dental fluorosis by Dean method. Six copies of the urinary fluoride were sampled in different age groups. The fluorine content in water and urine was determined by F-ion selective electrode. The situation of clinical skeletal fluorosis of adults over 16 years of age was investigated, 20 adults (evenly divided between men and women) in the villages of medium and heavy types were examined by X-ray for skeletal fluorosis. Results In 3 village fluoride content of drinking water exceeded the national drinking water standards ( <1.0 mg/L) of 85 surveyed villages with improved-water. Among the 16 projects, 8 were intermittently running and 3 were retired, leaving only 31.25% of the projects active. Theprevalence of enamel fluorosis was 41.13%( 116/282), that of skeletal flurosis was 47.95%(969/2021) and that of X-ray checked was 20.73% (17/82). The median of urine fluoride was 1.06 mg/L and the scope was 0.20 - 9.44 mg/L.Conclusions Most of the improved-water projects do not normally supply water in the disease ward of Guide county. Therefore, there is an increasing trend of the disease, so further control measures are needed.
