Cancer Research and Clinic 2011;23(5):328-330
Objective To analysis the clinical characteristics, treatment and prognosis for patients with cervical cancer with lymph lode of paraaortic and /or supraclavicular metastasis after combined treatment in two years. Methods Data of 20 patients with lymph lode of paraaortic and /or supraclavicular metastasis of cervical cancer were analyzed retrospectively. Results There was no evidence of lymph node of paraaortic and supraclavicular metastasis before the first combined treatments according to the MRI/CT/SPECT scans in these 20 patients. However, lymph lode of paraaortic and/or supraclavicular metastasis were seen in two years after treatments, the shortest is two months. One patient was progressing during treatment whose pathologic diagnosis is mucinous adenocarcinoma, died in 6 months from treatment start. There was only paraaortic metastasis in 15 patients, among these, 4 patients were found lymph lode of left supraclavical metastasis after retreatments in 3-6 months. Both paraaortic and left-supraclavical lymph node metastasis in 4 cases. Among these 20 cases, recurrence and to give up treatment, whose median survival time is 7.50 months, recurrence and to gain treatment, whose median survival time is 18.98 months, there was significant difference (x2=7.23, P<0.01). Conclusion Patients with cervical cancer with lymph lode of paraaortic and/or supraclavicular metastasis after combined treatment will obviously extend survival time after retretments, which has positive therapy significance.

Objective To compare the clinical application between peripherally inserted central catheterization(PICC) and subclavian central venous catheterization in severely ill patients.Methods A prospective study was carried out in 80 severely ill patients who had been randomly divided into two groups: receiving either PICC(PICC Group,40 patients) or subclavian central venous catheterization(Subclavian Group,40 patients).The success rate,the puncturing time,and the incidence of adverse reactions in the two groups were observed.Results The rate of successful puncture on one session was higher in the PICC Group(92.5%) than in the Subclavian Group(75.0%)(?2=4.501,P=0.034).And as compared with the Subclavian Group,the PICC Group reported a shorter puncturing time(15.7?5.3 min vs 23.9?6.3 min;t=-6.263,P=0.000) and a lower rate of adverse reactions(10.0% vs 27.5%;?2=4.021,P=0.045).Conclusions Use of peripherally inserted central catheterization is simple and safe to perform,superior to subclavian central venous catheterization.

Objective To investigate circulating betatrophin levels in non-alcoholic fatty liver disease patients (NAFLD). To explore its association with various metabolic parameters in Chinese subjects. Methods From August 2014 to April 2015 , 58 patients with NAFLD and 41 non-NAFLD control subjects with age and sex matched were enrolled in the Department of Endocrinology of Zhujiang Hospital. Results In NAFLD group, serum betatrophin concentrations significantly increased (781.96 vs. 431.89 pg/mL, P < 0.05) and associated only with HDL-cholesterol level. In normal group, betetrophin levels are associated with multiple metabolic parameters, such as fasting glucose, insulin, C peptide, HOMA-IR, QUICK index and HDL-C levels. Conclusions Serum betatrophin concentration significantly elevated in non-alcoholic fatty liver disease patients and was negatively correlated with HDL-C level (r = -0.479, P < 0.001).

Objective To investigate the value of shear wave elastography (SWE)for differential diagnosis of benign and malignant thyroid nodules.Methods A total of 1 56 patients referred for surgery of thyroid nodules underwent standard ultrasound as well as elastography.The following characteristics of all the nodules were assessed:location,size,shape,margin,echogenicity,calcification and blood flow.The SWE elasticity indices of maximum (Emax),mean (Emean),minimum (Emin),and standard deviation (Esd) were automatically calculated by the US system.Thresholds were calculated by receiver operating characteristic (ROC ) curve analysis.The diagnostic performance of conventional US and SWE were compared.Histopathologic examination was used as the reference standard.Results Among a total of 1 56 nodules,1 1 8 were malignant and 38 were benign.SWE elasticity indices were significantly higher in malignant than in benign nodules (P ≤0.001 ).Sensitivity and specificity for predicting malignancy were 83.9%,92.1 % respectively using Emean with a threshold of 32.1 kPa,the specificity was significantly higher than using conventional ultrasound (P <0.05 ).Area under the ROC curve (Az)of Emean was highest (0.880,95% CI:0.81 7,0.943),however the differences were not significant(P >0.05).Conclusions SWE provides higher specificity for predicting malignancy without losing sensitivity.

Objective To investigate the relationship between the genetic polymorphisms of glutathione S-Transferase M1,T1 and the susceptibility to sporadic colorectal adenocarcinoma(SCRAC) and smoking and alcohol consumption in Chinese Hans.Methods Multiplex polymerase chain reaction (M-PCR) was used in the study of genetic polymorphisms of GSTM 1,T1 gene.Logistic analysis was performed to elucidate the roles of GSTM1,GST1,smoking and alcohol.Results The null GSTM1,T1 genotypes could increase the susceptibility to SCRAC(OR=1.711,95% CI:1.043~2.805;OR=1.734,95% CI:1.057~2.843),but smoking and alcohol consumption made no significant effect on SCRAC(OR=0.584,95% CI:0.356~0.958;OR=0.378.95% CI:0.217~0.657).Further stratification of the SCRAC patients by chnical features showed that there were no relationship between the GST M1,T1 genotype and the age of the SCRAC patients.But the frequency of null GSTM1 genotype was significantly associated with distal colon adenocarcinoma (P=0.021),colorectal adenocarcinoma of Dukes C classification (P=0.003) and poor difierentiation (P=0.020),respectively.The frequency of null GSTF1 genotype was only higher in colorectal adenocarcinoma of Dukes C classification(P=0.041).No relationship was found between the location,the degree of differentiation and the frequency of null GSTF1 genotype(P>0.05).Furthermore,the frequencies of homozygous deletion in GSTM1,T1 genes were found to be significantly increased in SCRAC patients than those in healthy controls(38.9%VS25.7%.P=0.023).Conclusion The GST genotype is strongly correlated with SCRAC incidence in Chinese Hans.The null GSTM1,T1 genotypes can enhance the genetic susceptibility to SCRAC.while smoking and alcohol consumption have no significant effect on the susceptibility to SCRAC.

Objective To construct eukaryotic expression plasmid pIRESneo3-pigment epithelium-derived factor (PEDF) and detect its transient expression in SP2/0 cells. Methods Specific primers were designed based on the mature peptide sequence of human PEDF cDNA in the GenBank. Human PEDF gene was cloned into the eukaryotic expression vector pIRESneo3. The PEDF DNA was transfected into SP2/0 with LipofectamineTM 2000. The recombinant human PEDF protein expressed in SP2/0 cell culture supernatant was identified by Western blot and enzyme-linked immunosorbent assay. The biological activity of the recombinant human PEDF was measured by 3-(4,5-dimethylthiazol-z-y1)-2,5-diphenytetrazolium bromide(MTT) method. Results PCR amplification, restriction enzyme digestion and DNA sequencing confirmed that the mature peptide sequence of human PEDF cDNA was successfully cloned into the eukaryotic expression vector pIRESneo3. And the plasmid was transfected into SP2/0 cells, which could secret PEDF. Western blot analysis showed that there was only one obvious band at the position of relative molecular weight of 50 000, and it is equivalent to the expected value. Enzyme-linked immunosorbent assay suggested that the content of PEDF began to rise after transfection, and peaked at 36 h [(0.92±0.04) μg/ml]. The proliferation of human umbilical vein endothelial cell line was significantly inhibited by supernatant after transfection of 36 h (P<0.05). Conclusions The eukaryotic expression plasmid pIRESneo3-PEDF had been successfully constructed and active human PEDF was transiently secreted, which made a foundation for further study of stable expression and purification of PEDF. This protein could be a potential medication for preventing and managing retinopathy of prematurity.
