Objective To evaluate the merits and demerits of three different closure methods for femoral artery access site in the interventional therapeutic procedures for senile patients with coronary artery disease. Methods We managed the femoral artery access sites in 60 cases undergoing interventional operation using three different hemostasias, including manual compression, Femostop equipment and Perclose suture (20 cases for each group). The procedure time, time for patients staying in bed, expenditure obedience, the percentage of procedure failure and vagal vascular reflex, and local vascular complications were observed and analyzed statistically. Results The study showed that the procedure time in Perclose suture group was about 12 minutes, much shorter than that in finger pressing and Femostop equipment groups (respectively 23 and 55 minutes, P

Objective To investigate the clinical significance of antinucleosome antibody (AnuA) in the patients with lupus erythematosus (LE) through detecting the serum level of AnuA in different types of LE patients before and after treatment. Methods Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum level of AnuA in 31 SLE patients, 26 SCLE patients, 7 DLE patients, 6 scleroderma patients, 5 dermatomyositis patients and 30 healthy controls. Among them, the serum levels of AnuA before and after treatment were detected in 15 SLE patients and 10 SCLE patients. Clinical data, laboratory test results and the scores of SLE disease activity index (SLEDAI) were analyzed with SPSS11.0 software. Results The serum levels of AnuA in SLE patients were higher than those in SCLE, DLE, scleroderma, dermatomyositis patients and healthy controls(P

Objective We reported previously that single nucleotide polymorphisms SNP) + 11G ＞ A in intron 3 of the human urate transporter 1 (hURAT1) gene are associated with hyperuncaemia in Han Chinese.The aim of the present study was to evaluate the effect of the variants on hURAT1 function.Methods The wild-type,mutant-type hURAT1 and exon 5-null hURAT1 were constructed,and respectively microinjected into the zebrafish embryo yolks.The subcellular localization of different genotypes of hURAT1 was detected by confocal laser scanning microscope.Results Compared with wild type,the mutant recombinant plasmid transcribed two types of mRNA spliceosome,the wild type and the exon 5-null type.The hURAT1 wild type protein was prominent localized on cell membrane,while the mutant type and exon 5-null hURAT1 proteins were distributed uniform in the cytoplasm but not on the cell membrane.Conclusion The hURAT1 variant + 11 G ＞ A resulted in an alternative splicing of hURAT1 mRNA-exon 5-null type.Its protein product exhibited a different subcellular localization compared with that of wild type.

ObjectiveTo discuss the value of immunochemical fecal occult blood test (IFOBT) in diagnosis of colorectal diseases.Methods Two hundred and fifty-one patients who taken IFOBT and chemical fecal occult blood test(CFOBT) from January 2008 to August 2011 were enrolled in this study.They were definitely diagnosed by total colonoscopy combined with pathology.ResultsThe positive rate of IFOBT and CFOBT in colorectal cancer patients was 100.0％(57/57) and 84.2％(48/57),there was significant difference (P ＜ 0.05).The positive rate of IFOBT and CFOBT in colorectal polyp patients was 38.6％ (32/83) and 10.8％(9/83 ),there was significant difference(P ＜ 0.05 ).The positive rate of IFOBT and CFOBT in inflammatory bowel disease patients was 100.0％(31/31) and 80.6％(25/31),there was no significant difference (P ＞ 0.05).Thepositive rate of IFOBT and CFOBT in non-specific enteritis patients were 86.8％ (33/38) and 73.7％ (28/38),there was no significant difference (P ＞ 0.05 ).The positive rate of IFOBT and CFOBT in normal colorectal cases was 2.4％(1/42) and 19.0％(8/42),there was siguificant difference (P ＜ 0.05).ConclusionsIFOBT is better than CFOBT in diagnosis of colorectal cancer and colorectal polyp.IFOBT has lower false positive rate.

OBJECTIVETo observe the effects of moxibustion with different temperatures on cholesterol and skin around "Shenque" (CV 8) in mice with acute hyperlipidemia, and to explore the correlation between moxibustion effect and transient receptor potential vanilloid 1 (TRPV1).

METHODSEight mice among 32 mice of C57BL/6J wild type (WT) were selected into a blank group, and the remaining 24 mice were made into the acute hyperlipidemia model by injection of egg yolk. After model establishment, the mice were randomly divided into a model group, a 38 °C moxibustion group and a 46 °C moxibustion group, 8 mice in each group. The temperature was (38 ± 1) °C in the 38 °C moxibustion group and (46 ± 1) °C in the 46 °C moxibustion group. "Shenque" (CV 8) and "Zusanli" (ST 36) were selected in the two groups; moxibustion was given for 10 min per time, once a day for 2 times. Mice in the blank group and model group were treated with immobilization and moxibustion was not given. After treatment, the level of serum cholesterol was tested by oxidase method; the morphology of skin around "Shenque" (CV 8) was observed by HE staining; the expression of TRPV1 in skin was measured by immunohistochemistry.

RESULTS(1) Compared with the blank group, the level of serum cholesterol was increased in the model group (P < 0.001); compared with the model group, the level of serum cholesterol was reduced in the 46 °C moxibustion group (P < 0.001); compared with the 38 °C moxibustion group, the level of serum cholesterol was reduced in the 46 °C moxibustion group (P < 0.01). (2) There was slight change of morphology and structure in skin tissue in the 38 °C moxibustion group, while obvious change was observed in the 46 °C moxibustion group, indicating specific change. (3) The difference of the expression of TRPV1 in skin was significantly different between 46 °C moxibustion group and blank group, model group (both P < 0.01); it was also different from the 38 °C moxibustion group (P < 0.05).

CONCLUSIONMoxibustion temperature is one of the important factors affecting the cholesterol and acupoint skin. The effects of moxibustion are related to TRPV1.

OBJECTIVE: To explore the expression and significance of programmed cell death 5 (PDCD5) and Bcelllymphoma/lewkmia-2(Bcl-2) in sinonasal squamous cell carcinoma (SNSCC). METHOD: Immunohistochemical method and Western Blot method was used to determine the expression of PDCD5 and Bcl-2 in specimen of SNSCC in thirty cases, sinonasal inverted papillomas (SNIP) in thirty-eight cases, and normal nasal mucosa in twenty cases. RESULT: (1) The expression of PDCD5 protein in SNSCC significantly decreased compared with SNIP and normal nasal mucosa. (2) The expression of Bcl-2 protein in SNSCC up-regulated obviously compared with SNIP and normal nasal mucosa. (3) Positive rate of PDCD5 protein and Bcl-2 protein in well, moderate and low differentiatied group is respectively 100.00%, 83.33%, 38.89% and 50.00%, 70.83% and 100.00%, the difference was statistically significant (P < 0.05). (4) In the follow-up cases, the survival rate of the patients with higher expression of PDCD5 protein was higher, but that with lower expression of Bcl-2 protein was higher. CONCLUSION The inactivation of PDCD5 protein and the activation of Bcl-2 protein may play an important role in the development of SNSCC, and there are a positive correlation between PDCD5 and Bcl-2 protein in SNSCC, which may be identified as a new therapeutic target.
