To preliminarily determine the appropriate dosage of carboplatin (CBP) at AUC of 5 mg.Ml(-1).min(-1) in the combination chemotherapy for Chinese senile patients with non-small cell lung cancer (NSCLC). Thirty-five Chinese senile patients with NSCLC in advanced stage (III/IV) were given 96 cycles of combination chemotherapy. Chemotherapy schedules included Taxol+CBP, Gemzar+CBP and NVB+CBP. The dose of CBP was at 5 mg.mL(-1).min(-1) of area under the concentration-time curve (AUC). Side effects and quality of life were observed before and after the chemotherapy. Myelosuppression was severe and commonly observed. Grade 3/4 of granulocytopenia was found in 47.9% (46/96) of the patients and grade 3/4 of thrombocytopenia was noted in 28.1% (27/96) of the subjects. However, other side effects were slight. The mean score of quality of life (QOL), according to the criteria of QOL for Chinese cancer patients had reduced 6.8. At 5 mg.mL(-1).min(-1) by AUC, the hematological toxicity of CBP was severe and it had some negative effects on the QOL. The administration of CBP at 5 mg.mL(-1).min(-1) by AUC may be too high for Chinese senile patients with non-small cell lung cancer.

BACKGROUND:cellmarker technology has been widely applied in many studies concerning celltransplantation. Chlormethylbenzamido-1,1-dioctadecyl-3,3,3’3’-tetramethylin-docarbocyamine (CM-DIL) and 4’,6-diamidino-2-phenylindole (DAPI) are commonly used for labeling cells. To our knowledge, there are few reports on comparing the two fluorescent dyes.
OBJECTIVE:To compare the effects of CM-DIL and DAPI on labeling bone marrow mesenchymal stem cells in vitro and in vivo.
METHODS:Isolation and expansion of bone marrow-derived mesenchymal stem cells were performed according to attachment culture. The cells were labeled by CM-DIL and DAPI, respectively. cellviability was assessed via trypan blue exclusion assay. Growth curves of bone marrow-derived mesenchymal stem cells were depicted using MTS assay. The reduction of fluorescent intensity was observed under an inverted fluorescent contrast phase microscope from passage 1 to passage 3 after labeling. Myocardial infarction was induced by left anterior artery ligation in Sprague-Dawley rats. One week later, bone marrow-derived mesenchymal stem cells labeled by CM-DIL or DAPI were injected randomly into the border area of infarct myocardium. After 3 days, transplanted celldistribution was examined under the fluorescent microscope through paraffin sections and frozen sections respectively.
RESULTS AND CONCLUSION:In vitro, bone marrow-derived mesenchymal stem cells labeled by both CM-DIL and DAPI showed decreased cellproliferation during the early period;the percentage of fluorescent-positive cells was approximately 100%in the two groups;however, the fluorescent intensity was significantly reduced from passage 1 to passage 3 in bone marrow-derived mesenchymal stem cells labeled by DAPI. In vivo, the transplanted cells were detected in a concentrated way both on the paraffin sections and frozen ones;the background color of frozen sections was lower in the CM-DIL group than in the DAPI group;false positive results of fluorescent expression could be eliminated in the CM-DIL group by using fluorescent mounting medium with the fluorescence of DNA staining. These data indicates that CM-DIL is more appropriate to in vivo tracing cells than DAPI.

OBJECTIVETo evaluate effectiveness therapeutic regimens for obstructive sleep apnea hypopnea syndrome (OSAHS) children at an acceptable cost.
METHODThis study was performed at Yuying Children's Hospital of Wenzhou Medical University from Mar. 2008 to Dec. 2010. Prospective random number table method was used for the analysis; 60 children with mild OSAHS were divided into Mild OSAHS Montelukast Treatment (MM) group and Mild OSAHS Adenotonsillectomy Treatment (MAT) group. 32 children in MM group were treated with leukotriene receptor antagonists (LTRAs), while 28 children in MAT group were treated with adenotonsillectomy. Also, 58 children with moderate and severe OSAHS were divided into severe OSAHS Montelukast Treatment (SM) group and severe OSAHS Adenotonsillectomy Treatmen (SAT) group. Twenty-two children in SM group were treated with LTRAs, while 36 children in SAT group were treated with adenotonsillectomy. All selected children were evaluated by polysomnography (PSG) and Obstructive Sleep Apnea-18 (OSA-18) items before and after a six-month treatment. Both records were taken and analyzed, surgical complications and the reason for non-remission after operation were also analyzed. Two therapies were compared based on economic consideration and therapeutic effect. Result (1) PSG: A significant change of a significant change of Apnea Hypopnea Index (AHI) was observed in MM group after the treatment (before receiving the treatment 4.56 ± 1. 26, and after receiving the treatment 3. 48 ± 1. 52, t =3. 50, P <0. 05). But for oxygen desaturation Index (ODI) (MM group 2. 18 ± 2. 19, and MAT group 1. 80 ± 2. 34) and Lowest Oxygen satuation (LSaO2) (MM group 91. 66 ± 2. 34, and MAT group 92. 79 ± 2. 18), there was no significant difference in MM group and MAT group after the treatment (ODI, t =0. 65, and LSaO2 t = - 1. 93, P >0. 05). (2) OSA-18 scores: Significant differences were found in sleeping disorder (before 14. 81 ± 6. 28, and after 10. 56 ± 3. 57), the degree of familial stress (before 13. 56 ± 3. 54, and after 8. 97 ± 2. 96), and OSA-18 total scores (before 52. 66 ± 1. 11, and after 42. 56 6. 48) in MM group after the treatment (sleeping disorder Z - 3. 14, the degree of familial stress Z = -4. 50, and OSA-18 total scores Z= -4. 01, P <0. 05). (3) In addition to the cost of drugs, groups with surgical treatment had a larger economic burden than those with LTRAs treatment. (4) Treatment was totally effective for 28 children (88%) in MM group, and 28 children (100%) in MAT group. Meanwhile, treatment also achieved an obvious effect on 2 children (9%) in SM group, and in 35 children (97%) in SAT group. In MAT group, 3 children improved (11%). And in SAT group, 7 children improved (19%), but treatment was found to be ineffective in 1 case (3%). Among those effective and ineffective cases in groups with surgical treatment, there were 9 children with nasal diseases.
CONCLUSION(1) Surgical treatment is recommended as the first choice for children with moderate and severe OSAHS. And for those who also suffer from nasal diseases, treatment combining drugs with surgery is necessary. (2) LTRAs therapy has a good effect for mild OSAHS. Surgery is also recommended when drugs could not achieve any obvious improvement in clinical symptoms of children with mild OSAHS.

Objective To investigate the effect of different amplification methods and probes with various length on the results of comparative genomic hybridization (CGH) analysis of pre-implanted single blastomere and to establish the basis for preimplantation genetic diagnosis.Methods Twenty blastomeres of embryo at 6-8 cells stage were randomly divided into A and B group with 10 in each.Twenty peripheral blood lymphocytes from a healthy man were similarly divided into C and D group with 10 in each.Degenerate oligonucleotide primed polymerase chain reaction (DOP-PCR) was used to amplify whole genomic DNA in group A and C,and multiple displacement amplification (MDA) was used in group B and D for whole genome amplification (WGA).The specificity of resultant products was confirmed by amplification of TBX1 gene exon 2.CGH was performed respectively with 250-750 bp and 750-2000 bp probes prepared from the amplified whole genomic DNA.The result of CGH was verified by sex-determining region of Y (SRY).Results (1) Nine of the 10 samples in group A and all in group C were amplifiable by DOP-PCR,but there were multiple non-specific bands in the amplification of TBX1 exon 2 when WGA products were used as templates.When 250~750 bp probe was used in CGH,1 of the 5 blastomeres was failed and another one had different karyotype from that analyzed by SRY.(2) All samples in group B and D were successfully amplified by MDA,and the non-specific bands were significantly less in the amplification of TBX1 exon 2.All 5 blastomeres were successful in CGH with the 250~750 bp probe.Moreover,the karyotype was in agreement with that of SRY.(3) When 750 ~ 2000 bp probe was used,the CGH results were suboptimal.Conclusions In WGA of single blastomere,MDA is superior to DOP-PCR in the stability and specificity.The karyotype image detected by CGH with the 250~750 bp probe is clear and homogenous.
