Purpose:To observe the efficacy of capecitabi ne in the treatment of relapsed breast cancer. Methods:21 patients with relapsed breast cancer were treated. C apecitabine was administered twice a day at the dose of 2 500 mg/(m 2?d) f or two weeks. 21 days was one cycle. Patients could be evaluated after at least 2 cycles treatment. Results:20 patients could be evaluated. There were no complete response but 6 partial response, 8 stable disease and 6 progressive disease in t he group. The response rate was 30.0%. The common toxic effects were hand-foot syndrome (61.1%), nausea and vomiting(66.7%), leucopenia (42.9%) and skin pigm entation (23.8%). Conclusions:Capecitabine is effective for the relapsed breast c ancer patients who have been treated with anthracycline and taxanes. The toxic e ffects are mild and the tolerance is well. Capecitabine can be used as the secon d line regimen for relapsed breast cancer.

Objective To investigate the right ventricular function of patients with chronic pulmonary hypertension using Doppler tissue imaging(DTI)and to evaluate the relationship between DTI parameters and pulmonary artery systolic pressure(PASP).Methods Thirty-five patients with chronic pulmonary hypertension and thirty-five healthy subjects underwent Doppler tissue echocardiographic evaluation of right ventricular function.The tricuspid lateral annular systolic velocity(Sm),early(Em)and late(Am)peak diastolic velocities,isovolumic contraction time(IVCT)and isovolumic relaxation time(IVRT)were acquired from apical 4-chamber view.Results When compared with control group,Sm,Ea and Em/Am values were found to be lower and Am,IVRT values higher in patients with chronic pulmonary hypertension.When all patients were analyzed,there was a significant positive correlation between PASP and IVRT(r=0.78,P

Objective To investigate the therapeutic and preventive method of foreignbodies in esophagus.Methods Clinical date of 78 cases of foreignbodies in esophagus were analyzed retrospectively.Results Among the 78 foreignbodies in esophagus,76 cases were removed from esophagus in different way.2 cases fulled into mastach.No severe complication occurred.The cure rate was 97％.Conclusions Foreignbodies in esophagus should be removed as soon as it is diagnosed.It is important that correctly treating foreignbodies in esophagus can reduce the incidence of severe complications.

Objective To investigate the clinical values and characteristics of whole body bone ima-ging (SPECT/CT)in detecting bone metastases in the preoperative patients with lung adenocarcinoma or squa-mous cell carcinoma for staging and determining the best treatment plan.Methods Eighty-two preoperative patients with primary pulmonary adenocarcinoma or squamous cell carcinoma performed 99 Tcm-MDP SPECT/CT whole-body bone imaging.One week before surgery,parts of positive lesions performed MRI scan.The differ-ence of the incidence of bone metastasis was analysed by χ2 test.Results In all 82 patients with lung cancer, there were 38 adenocarcinomas and 44 squamous cell carcinomas.Bone metastases were detected in 38 cases, the incidence rate was 46.3%.Of which,among lung adenocarcinoma,the incidence rate was 57.9% (22 /38),and the incidence rate was 36.4% (1 6 /44)in lung squamous cell carcinoma,and the difference was sta-tistically significant (χ2 =1 2.66,P =0.027).The most common area was bilateral ribs,followed by vertebra, pelvis,bones of the extremities and skull.Conclusion Lung adenocarcinoma compared with squamous cell carcinoma is prone to bone metastases,and bone metastases are more common in bilateral ribs.It has important value that whole body bone imaging in screening for bone metastases of pre-operative patients with lung cancer for staging and making the treatment plan.

Objective To investigate the clinical features of and gene mutations in a Chinese Han pedigree with piebaldism. Methods Clinical data were collected with informed consent from a pedigree with piebaldism, processed and documented. A clinical genetic analysis was conducted and pedigree chart was drawn. Genomic DNA was extracted from the peripheral blood of 14 patients and 40 unaffected individuals in the family as well as 50 unrelated human controls, and subjected to the amplification of 21 exons and flanking sequences of the KIT gene by PCR. Sequence analysis was performed by Mutation SurveyorTM. Results There were 73 members in the family, and of them, 14 were diagnosed with piebaldism according to typical clinical features. Piebaldism was inherited in an autosomal dominant pattern in this family. A heterozygous 4-base insertion mutation 1900insATGA in exon 13 of KIT gene was identified in all the 14 affected family members, which resulted in a frame-shift mutation at codon 634 and produced a premature translation termination codon. This mutation was undetected in either the unaffected family members or unrelated controls. Up to the time of this writing, this mutation had not been previously reported. Conclusion The novel mutation 1900insATGA in the KIT gene may be the cause of clinical phenotype of piebaldism in the family.

The purpose of this study is to investigate the intracellular transporters effect and the cytotoxicity of carboxyl nanodiamond (CND) - podophyllotoxin (PPT). Nanodiamond (ND) was treated with mixed carboxylic acid and finally got 64 nm CND by centrifugation, and then it was reacted with PPT to form CND-PPT. UV spectrophotometry was used to calculate the content of PPT in CND-PPT, the particle size distribution and zeta potential were measured by Dynamic laser scattering instrument. CND, PPT, CND-PPT and CND + PPT (physical mixture of CND and PPT) were characterized by Fourier transform infrared spectroscopy, at the same time, thermal analysis and element analysis were used to estimate the content of the PPT in CND-PPT. The affect of CND, PPT, CND-PPT on HeLa cell was measured with MTT assay. The results showed that content of PPT combined with CND accounted for about 10%. MTT assay showed that CND has low cytotoxicity and CND-PPT can increase the water soluble of PPT. As a conclusion, CND as a hydrophilic pharmaceutical carrier combined with PPT is able to increase the water solubility of PPT, at low concentration, CND-PPT can enhance the antitumor activity in comparison with PPT, so CND can be used as a potential anticancer drug carrier.

AIM: To establish the fingerprint chromatography of Yujin Injection (Herba Houttuyniae, Flos Lonicerae) by GC. In the paper the authors examine the similarity among standard and sample chromatogra-phies. METHODS: GC was used to analyze the volatile ingredients, SGE 30QC3 colume (30m? 0.32mm? 0.5?m) was used with column temperature from 100℃ to 170℃ with 2℃?min -1 below 150℃ and 5℃?min -1 above 150℃, flow rate at 1.0mL?min -1 and detector temperature at 200℃. RESULTS: Standard fingerprint consisted of 17 marker peaks, the comparison of similarity's RSD to the injection of different batch had no more than 2%. CONCLUSION: According to the selected chromatographic conditions, a good fingerprint of the injection has been described. The method is simple, accurate with good reproducibility. It may be practical for the quality control of Yujin Injection.

Objective To investigate the morbidity,clinical feature,diagnosis and therapy of ovarian disease in children.Methods Eighty-two children with ovarian disease were admitted and treated in Nanjing children's hospital from Jan.1992 to Jan.2007,were analyzed retrospectively with age,emergency admissions or not,dwell,pathology and method of operation.Results The age of 82 patients ranged from 1 day to 14 years old and the mean age was 6.7 years old.Thirty-one cases(37.8%) were emergency admissions and 51 cases(62.2%) were routine admissions.Twenty-seven cases(32.9%) were rural patients and 55 cases(67.1%) were urban patients.Forty-five cases(54.8%) were nontumorous disorder,31 cases(37.8%) were benign tumor and only 6 cases(7.4%) were malignant tumor.About the morbidity,12 patients(14.6%)were admitted from 1992 to 1996,24 patients(29.5%) from 1997 to 2001 and 46 patients(55.9%) from 2002 to 2007.Chemotherapy were carried out in 6 cases with malignant tumor in internal medicine,2 cases with sexual precosity kept observation,the others were cured.Conclusions Ovarian disease can occur at any age in children.The clinical manifestation is characterized mainly by acute abdomen.The incidence of ovarian disease of children in urban areas is higher than that children in rural areas.The morbidity continues to show an upward tendency and the pathologic manifestations are mostly benign,laparoscopic operation has obviously superiority.
