In China,surgery and drug treatment received more attention, but the overall rehabilitation was ignored. This article summarized the status of breast cancer patients's rehabilitation in lymphoedema, upper limb dysfunction, psychological problem, sexual dysfunction, childbirth trouble,dystrophy, follow-up visit and family-society support, and so on.

Objective Acute massive pulmonary embolism(PE)is a clinical emergency requiring rapid and supportive measures.With the development of interventional technology and devices,percutaneous mechanical thrombectomy(PMT)is considered to be an alternative for the treatment of PE,though there is still relative lack of clinical experience.The purpose of this study is to evaluate the clinical efficacy and safety of PMT in the management of acute massive PE.Methods The clinical data of massive PE patients treated with interventional methods were collected and analyzed in a retrospective way.From Jan.2003 to Jan.2008,6 patients(5 males and one female,with a mean age of 62 years)with acute massive PE,which was initially diagnosed by computed tomography and finally confirmed by pulmonary angiography,were treated with percutaneous catheter fragmentation and/or Straub Rotarex thrombectomy device.Results The improvement of clinical status and restoration of blood flow in the main branches of pulmonary artery were obtained in all patients.Oxygen saturation(SaO2)increased from preoperative(79.5±5.3)%to postoporative (92.8±3.4)%,with P＜0.01.Partial arterial oxygen pressure(PaO2)increased from preoperative(58.0±9.8)mmHg to postoperative(88.7±4.1)mmHg(P＜0.01).After PMT treatment,the mean pulmonary artery pressure(PAP)decreased from preoperative(40.8±7.8)mmHg to postoperative(29.8±8.0)mmHg (P＜0.01).Miller index decreased from preoperative 0.54±0.03 to postoperative 0.18±0.07(P＜0.01).During a clinical follow-up period ranged from 1 to 5 years,four patients showed no recurrence of PE,the other two patients lost touch with the authors.Conclusion The preliminary experience in onr series suggests that PMT is an easy,effective and safe therapy in the clinical management of acute massive PE,especially when thrombolysis is contraindicated.

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.

BACKGROUND:The study confirmed that adding tricalcium phosphate or pearl powder in polylactic-co-glycolic acid can complement the performance of both, which provides a good environment for cels and makes a faster and better growth of cels. OBJECTIVE:We used polylactic-co-glycolic acid as matrix, composited with pearl powder or tricalcium phosphate to prepare scaffolds by low-temperature deposition manufacturing. METHODS:Low-temperature deposition manufacturing was utilized to prepare composite scaffold of polylactic-co-glycolic acid/pearl powder or polylactic-co-glycolic acid/tricalcium phosphate at the ratio of 10:0, 5:2, 7:3 and 6:4. Microstructure, contact angle and compression modulus of elasticity of scaffolds were detected. MC3T3-E1 cels basicaly fused at 1×104/cm3 were seeded in the pure nonporous polylactic-co-glycolic acid scaffold, pure polylactic-co-glycolic acid scaffold with holes, polylactic-co-glycolic acid/pearl powder at 5:2 and polylactic-co-glycolic acid/tricalcium phosphate at 5:2 separately for 1 and 3 hours. Cel adhesion rate was detected using flow cytometry. After incubation for 1, 4 and 7 days, cel proliferation was measured using Alamar Blue method. RESULTS AND CONCLUSION:Pure polylactic-co-glycolic acid scaffold had cross-linked microporous structure, with pore size of 3-15 μm. Scaffolds ofpolylactic-co-glycolic acid/pearl powder at 5:2 or polylactic-co-glycolic acid/tricalcium phosphate at 5:2 had good continuous porous structure, with pore size of 10-25 μm. With increased content of pearl powder or tricalcium phosphate, the hydrophilicity of the composite scaffold increased. The addition of pearl powder or tricalcium phosphate could elevate compressive mechanical properties of the composite scaffold. With increased content, the mechanical property of the scaffold enhanced and then reduced. The addition of pearl powder or tricalcium phosphate improved the celular affinity of polylactic-co-glycolic acid and the biocompatibility of the scaffold. The biocompatibility of polylactic-co-glycolic acid/pearl powder scaffold at 5:2 was the best.

Objective To explore the change of sexual life quality and its influencing factors of premenopausal breast cancer patients.Methods 94 premenopausal breast cancer patients were included. Changes in Sexual Functioning Questionnaire short-form (CSFQ-14) was used and part of its items was changed. Their sexual life was evaluated before and after treatment by using depth interview and anonymous methods. Results 94 cases received face-to-face communication and study. 88 (93.6%) questionnaires were received, in which 81 (92.1%) questionnaires were effective. Their sexual life quality and sexual satisfaction significantly decreased and there was significant difference in the CSFQ-14 score (P<0.001) before and after treatment. The ratio of bad, worse, and worst sexual life were 39.5%, 29.6%, and 14.8% respectively after treatment. 65.4% of the patients had no sexual activity. The reasons included medical related factors, fear of cancer metastasis and recurrence, physical discomfort, poorer body image, partner sexual attitudes changed, life stress, common psychological problems, traditional ideas and so on. Conclusion Sexual dysfunction was obvious and sexual life quality significantly decreased in premenopausal breast cancer patients after treatment. Patients' physical and mental damage, the change of body image and spouse's attitude are significant influencing factors. It is necessary to give sexual rehabilitation guidance to patients and their spouses.

Objective To investigate the association between 5-hydroxytryptamine 2A receptor (HTR2A)gene T102C locus polymorphism and schizophrenia,and to provide basis for evidence-based medicine for the genetic background of schizophrenia.Methods PubMed,EMbase,CNKI,WanFang and Vip information databases were used to search full text of all the relevant studies about the association between HTR2A gene T102C locus polymorphism and schizophrenia,which were published during 2003 to 2012.Based on reviewing full text,the data were selected, evaluated and accessed. RevMan 5.1 and Stata 1 2.0 were used to perform the statistical analysis of those studies that were in accordance with the inclusive criteria. According to the different ethnicities, the obj ects were divided into two subgroups as European and Asian to analyze respectively. Also, depending on different inheritances, the obj ects were divided into five patterns including C/T allele, CC/TT, CC/CT+TT, CC+CT/TT and CC+ TT/CT genotypes to analyze respectively, including heterogeneity inspection, effect consoliating and publication bias assessment. Results A total of 11 studies were available for this analysis, including 2 443 schizophrenia patients and 2 469 controls.The Meta-analysis results showed that the allele of all people were OR=1.12,95%CI=0.96-1.31,P>0.05;CC/TT of all people were OR=1.11,95%CI=0.80-1.53,P>0.05;CC/CT+TT of all people were OR=1.13,95%CI=0.99-1.30,P>0.05;CC+CT/TT of all people were OR=1.18, 95%CI=0.93-1.50,P>0.05;CC+TT/CT of all people were OR=0.95, 95%CI=0.84-1.06,P>0.05.Conclusion Current evidence is insufficient to show that HTR2A gene T102C locus polymorphism may be associated with schizophrenia, suggesting that the gene polymorphism has no significantly genetic association with schizophrenia.

Objective To investigate the protective effect of a COX inhibitor,flurbiprofen (Flurb) on hepatic ischemia/reperfusion (IR) injury in rats and the action mechanism.Method C57BL/6 mice were randomized into sham,IR and Flurb (4 different doses) groups.The model of segmental (70％) warm hepatic ischemia was established in IR and Flurb groups.Flurbiprofen of different doses (5,7.5,10 and 15 mg/kg) was injected via the tail vein 20 min before ischemia.At different time points after reperfusion,liver cell necrosis and apoptosis were evaluated by HE and TUNEL staining.The COX and inflammatory cytokine gene expression was detected by using realtime PCR.Liver mitochondria were separated and mitochondrial permeability transition (MPT) pore sensitivity was examined by using swelling assay and fluorescence spectrophotometry assay.Result In flurbiprofen groups of different doses,the serum AST and ALT levels were significantly decreased at 6 h after reperfusion as compared with IR group.Moreover,10 mg/kg Flurb pretreatment significantly inhibited the mitochondrial permeability transition (MPT) pore opening,and thus alleviated liver cell damage and prevented mitochondria-related cell death and apoptosis by inhibiting COX-2 and inflammatory factor genes expression such as IL-1β,IL-6 and TNF-α.Conclusion Flurbiprofen protects mice from hepatic I/R injury possibly by inhibiting mitochondrial permeability transition and IL-1β,IL-6 and TNF-α expression,which may provide experimental evidence for clinical use of flurbiprofen to protect liver function in surgical settings other than its conventional use for pain relief.
