Objective Aim to explore how severe chyle blood serum effects on the End-point method of colorimetry,velocity method,immunological transmission turbidimetry(TIA)three types of common biochemical tests and their different influ-ences.Methods Collected 20 normal appearance serums,divided each pooled serum into A,B,C,D,E,F and G 7 experimen-tal groups and one control group.Each group contented for 1ml serum.Added intralipid 10,20,40,80,160μl and 320μl to the experimental groups from A to G in turn to prepare into different concentrations of simulate chylous samples.Tested each group by the End-point method of colorimetry,velocity method and TIA which represented by Glucose (Glu),uric acid (UA),Total bilirubin (TBil),aspartate aminotransferase (AST),gamma-glutamyl transpeptidase (GGT),lactate dehydro-genase (LDH),hypersensitive C reactive protein (hs-CRP),Apolipoprotein A1 (apoA1 )andβ2-microglobulin (β2-MG). Used pair T test for both experimental group and their control group.Results In terms of TIA,there were statistical differ-ences between all the experimental groups and their control groups in the three projects (t=-2.842~29.465,P<0.05).In terms of the End-point method of colorimetry,there were statistical differences between all the experimental groups and their control groups (t=-34.942~13.884,P<0.05)except for A group in Glu experiment (t=1.875,P=0.068>0.05).In terms of velocity method,there were no statistical differences between all the experimental groups and their control groups (t=-1.532~1.619,P>0.05)except for the B and C groups in GGT experiment (t=2.234&5.006,P<0.05).Conclusion Severe chyle blood serum had significant influence on the End-point method of colorimetry and TIA,as well as less influ-ence on velocity method.

【Objective】To explore the relationship of precancerous lesions of uterine cervix with human papillomavirus(HPV)DNA content in high risk women detected by the method of hybrid capture Ⅱ(HC2).【Methods】From September of 2003 to January of 2005,433 outpatients were collected in gynecology department of the Second Affiliated Hospital of Guangzhou University of TCM.Cervical HPV-DNA contents were detected by HC2.For those with HPV-DNA positive,Thinprep cytologic test(TCT)was done and further examination under colposcope such as multiple cervical biopsy and endocervical scraping smear was performed if TCT showed abnormalities of cytology.【Results】There were 128 patients with HPV-DNA positive,and 98(76.56%)with abnormal cytologic changes such as atypical squamous cell of undetermined significance(ASCUS),low-grade squamous intraepithelial lesion(LSIL)and high-grade squamous intraepithelial lesion(HSIL),which was more than those(23.44%)with normal cervical cells.For the patients with abnormalities of cytology,HPV-DNA content was higher than those with normal cervical cells(P

Fibroblast activation protein (FAP) is a marker protein of cancer-associated fibroblasts(CAFs). It is highly expressed in more than 90% of epithelial cancers and hardly expressed in normal tissues. Therefore, FAP is a very promising target. Radionuclide labeled FAP targeted molecular probes can be used for PET or SPECT imaging. In particular, 68Ga-FAP inhibitors (FAPIs) PET/CT has shown good prospects in the clinic, providing a new idea for early diagnosis, accurate staging and radionuclide treatment of tumors. In addition, FAP is also highly expressed in certain non-tumor diseases, especially those related to fibrosis. In this article, the research progress of radionuclide-labeled FAP targeted molecular probes is reviewed.

Background Constipation is a common complication after stroke, and the results investigated overseas showed the incidence was about 30% ～60%. The difference of results is so significant because the time investigated and the diagnosis criterion used are different. There are less relative report about risk factors of constipation and no report about the impact of constipation on pragnosis. The study is to investigate the incidence and risk factors of new-onset constipation after stroke in the patients with acute stroke and to evaluate the impact of new-onset constipation occurrence on the prognosis in the patients.Methods A prospective cohort study of new-onset constipation was performed to investigate 154 cases of acute stroke patients who were hospitalized from December 2003 to October 2004 in the department of neurology, the first Affiliated Hospital of Sun Yat-sen University. We recorded the demographics, medical history,stroke severity and medication used. National Institutes of Health Stroke Scale (NIHSS), Barthel Index (BI)and Modified Rankin Scale (MRS) were evaluated in the 1st week and 4th week after stroke to evaluate the neurological function and ability of an independent life. BI and MRS were recorded at the 12th week after stroke.Patients were then followed for the development of stroke, the event such as recurrence or death. Constipation was defined by Rome Ⅱ criteria.Results The incidence of new-onset constipation after stroke within 4 weeks was 55. 31%, and the highest risk was within seven days after onset of stroke. Cox regression showed that the incidence of constipation occurrence was strongly related to neurological functional status of patients in the 1st week assessed by BI and the transform of surrounding for defecation. In the 4th week and 12th week after stroke, the rates of poor prognosis in patients with constipation in middling state were both higher than patients without constipation, and the difference was statistically significant respectively(P ＜ 0. 01 ;P = 0. 012).Conclusions The new-onset constipation occurrence in acute stroke is very common and its main risk factor is functional status assessed by Barthel Index at the 1st week after onset and the transform of surrounding for defecation. The results indicate that the new-onset constipation occurrence after stroke has negative effects on the outcome of partial stroke patients.

Objective:To observe the effects of orbital bone density on the stress distribution of implant-bone surface.Methods:The 3D finite element analysis craniofacial model with eight HU values(300 -1 0 000)was established.A force of 20 N along the im-plant axis was applied on the model.The stress values and distribution were calculated and analyzed.Results:The peak of stress val-ue and displacement discreased as HU value increased.In the range of HU value 800 -1 000 HU,the peak of stress value and dis-placement of bone interface did not significantly change with the increasing of HU value.Conclusion:Orbital bone density is an im-portant factor on orbital implant failure when HU value below 800.

Objective:To investigate the mechanisms of decoy oligodeoxynucleotides(decoy-ODN) blockading Stat3 that inhibit breast cancer cells MDA-MB-231 proliferation.Methods:Stat3 decoy-ODN and scramble control were transfected into breast cell line MDA-MB-231, respectively. The cell proliferation capability was detected by cell counting; flow cytometry was applied to detect MDA-MB-231 cell cycle; FITC labeled decoy was observed by Reflected Light Fluorescence Microscope; the expression of the gene controlled by Stat3 was examined by means of RT-PCR and Western blot assay.Results:Stat3 decoy-ODN could be internalized into MDA-MB-231 cells and inhibit the growth of MDA-MB-231 cell via inducing its apoptosis. Stat3 decoy-ODN also could significantly reduce the expression of Stat3 controlling genes such as Bcl-xl,c-myc and CylinD1.Conclusion:Stat3 decoy-ODN can inhibit breast cell line MDA-MB-231 proliferation by blockading JAK/STAT pathway. This suggests that transcription factor decoy-ODN may serve as a novel therapeutic strategy for breast cancer.

By using microwave extraction, a GC/MS method was developed for the determination of polycyclic aromatic hydrocarbons ( PAHs) content in soil which is around the discharge ditch of oily wastewater, and a correlation analysis of the content of organic matter in soil was carried out. The results showed that PAHs in the surface soil pollution were mainly from 2 to 4 rings of low molecular PAHs, and the PAHs with high molecular were not detected. Each sampling point belongs to slight or moderate pollution and the overall assessment is moderate pollution, which is middle and low lever in comparison with soil data of central regions. The origin may be the low molecular PAHs of oil pollution along with the atmospheric transmission, but it cannot be completely excluded the possibility of fuel combustion pollution. No obvious correlation was found between the content of polycyclic aromatic hydrocarbons and organic matter.
