AIM: To investigate the effect of human amniotic fluid on the release of thromboxane A 2 (TXA 2), prostaglandin I 2 (PGI 2) and Leukotriene C 4(LTC 4) from blood cells. METHODS: 1 mL human amniotic fluid and 10 mL oneself blood collected from 38-41 weeks with cesarean section were cultured at 37℃ for 30 min, and then centrifuged. The supernatants were taken and stored at -70℃. TXB 2 and 6-Keto-PGF 1? of the superntants were determined by radioimmunoassay and LTC 4 by enzyme immunoassay. RESULTS: It was found that the levels of TXB 2 and LTC 4 in blood were elevated from (63.5?52.0) ng/L and (40.1?39.2) ng/L to (189.1?102.0) ng/L and (293.5?206.1) ng/L respectively (P0.05).CONCLUSION: Amniotic fluid might stimulate the release of TXA 2 and LTC 4 from blood, it might affect the balance of TXA 2 and PGI 2 in blood, which might play an important role in the pathogenesis of amniotic fluid embolism.

Objective To study the effects of cripto on migration, invasion, and liver metastasis of colorectal cancer cell. Methods After human colorectal cancer cell line SW480 was transfected by cripto small interfering RNA (siRNA), the mRNA and protein level were determined by Real-time RT-PCR and Western blot, respectively. The migration and invasion ability were evaluated by wound-healing assay and boyden chamber model, respectively. Thirty nude mice model of liver metastasis from colorectal cancer was established by splenectomy. Results The siRNA could down-regulate the level of mRNA and protein of cripto in a dose- and time-dependent manner. Suppression of cripto expression could inhibit migration and invasion ability of human colorectal cancer cell in vitro. The metastastic rate and tumor nodules were lower in transfection with cripto siRNA than in two control groups in vivo. Conclusions Cripto gene might play an important role in regulation of liver metastasis from colorectal carcinoma cell, and suppression of cripto gene by siRNA can inhibit liver metastasis of colorectal cancer.

Objective To evaluate the feasibility and indications of endoscopic submucosal dissection (ESD) by analyzing the early gastric cancer cases.Methods All the pathological materials of radical gastric resections in Huashan hospital from 2007 to 2011 were retrieved and the EGC cases were selected.All the cases in EGC group which met the extended ESD criteria were reviewed.Extended ESD criteria were cited from Treatment guidelines for gastric cancer in Japan edited by JGCA in 2001.The risk factors relevant with regional metastasis,such as invasive depth and differentiation degrees,were also analysed.Results In the recent five years,there were 1159 cases of gastric cancer undergoing radical gastrectomy in Huashan hospital including 210 EGC.According to the extended criteria of JGCA,151 cases could be candidates for ESD while 126 cases could be candidates for ESD according to the typical criteria for ESD.The local metastases of lymphatic or vascular involvement for mucosa cancer,muscularis mucosae cancer,sm1 and sm2 cancer were 6.75％,15.00％,23.25％,and 39.62％ respectively (P ＜0.05).Twenty-five cases had local metastases that met the extended criteria for ESD.Within the 210 EGC cases,the local metastases of differentiated type and undifferentiated type were 13.95％ and 47.37％ respectively (P ＜ 0.05).Conclusion Most EGC cases undergoing radical gastrectomy can be cured by ESD.Its metastases are highly correlated with invasion depth and differentiation,so indications of ESD should be assessed.

The diversity in Tibetan kefir grains and dynamics of the microbial community during the fermentation of Tibetan kefir by PCR-DGGE fingerprinting technique were studied.The results showed that bacterial community of Tibetan kefir grains was more complex than that of yeast.The bacteria communities between different Tibetan kefir grains showed 78%～84% similarity, and yeast 80%～92%.Bands B, E and N of DGGE profiles of the microbial community during fermentation of Tibetan kefir were present throughout the fermentation.Analysis of sequence date showed the majority of the DGGE bands of bacteria community corresponded to LAB, and the most intense band (band E) was completely homology to Lactococcus lactis.

Objective To investigate the abnormal situation and the characteristics of body mass index(BMI),blood pressure (BP),blood lipid(BL),and fasting plasma glucose(FPG) in residents of Chongqing.Methods Data of BMI,BP,BL and FPG were obtained from 16 367 residents receiving regular health examination in our Hospital in 2006.Results These metabolic indicators of this group were abnormal:The detection rate was 33.2%(42.5% in male and 17.6% in female)for overweight;7.4%(9.7% in male and 3.5% in female) for obesity;25.4%(30.0% in male and 17.6% in female) for hypertension;,38.9%(41% in male and 35.5% in female) for total cholesterol;26.1%( 34% in male and 12.8% in female) for triglyceride;23.7%(26.8% in male and 18.6% in female) for low-density lipoprotein;8.2%(11.8% in male and 2.2% in female) for high-density lipoprotein;3.2%(3.8% in male and 2.2% in female) for impaired fasting glucose;and 3.2%(3.9% in male and 2.0% in female) for diabetes meUitus.The detection rate of these metabolic disorders was significantly higher in men than those in women,and increased with age,which was significantly higher in people aged 30-40 years than in people aged less than 30 years.Conclusion The levels of BMI,BP,BL and FPG of health examination residents in Chongqing had its unique characteristics,and were abnormal significantly,it was very important to take regularly health examination after 30 yrs old.

Objective To establish a rabbit model of lumbar laminectomy and bone grains replantation and provide experimental evidence for the clinical application.Methods Eighteen healthy male New Zealand rabbits were selected and randomly divided into two groups:the control group (n=6) and experimental group (n=12).The rabbits of control group were given general anesthesia, and taking the L5 spinous process as the center to perfom left L5 laminectomy, using a micro lancet forceps to slowly bite the lamina and ligamentum flavum for fenestration and exposed to an approximately 0.8 cm x 0.3 cm sized bone window and then sutured the skin.The rabbits of experimental group were exposed to an approximately 0.8 x 0.3 cm sized bone window as well, and bone fragments were cut into small grains.Then the small bone grains were embedded in medical collagen sponge, to form an arch shape, and replanted them to the site of epidural fenestration.CT scan and histological changes were observed at 4, 8 and 12 weeks after operation.Results At 8 weeks after operation, CT examination showed that in the experimental group, a thin bone plate was formed by the bone grains.At 12 weeks after operation, the bone plate became thicker and was connected with the vertebral bone, and with continuous bone trabeculae.The spinal canal and volume were not obviously changed, and no spinal cord compression was observed. The rabbits of control group showed segment lamina defects, a small scar protruding into the spinal canal, and the vertebral canal was not completely reconstructed. Conclusions The bone grains replantation can effectively promote bone reconstruction in the laminectomized rabbits, and the formed bone plate can prevent epidural scar from intruding into the spinal canal, and can reduce the postlaminectomy adhesion.

0.05). There was only 2/109 cases (5.8%) need a second course of antibiotics because of likely infection and 102/109 cases (93.5%)need not any moor antibiotics. The mean period of antibiotic treatment in group Ⅰ, group Ⅱa and group Ⅱb were (1.2?0.5) days,(4.8?0.8) days and (9.3?1.8) days,respectively.There were significant differences(all P
