Objective To develop a new method, capillary electrophoresis(CE) based on molecular beacon(MB),for rapid detection of polymerase chain reaction(PCR).To explor the roles of the IL-13 gene exon4 A2044G single nucleiotide polymorphism(SNP) in the pathogenesis of bronchial asthma.Methods The IL-13 exon 4 was amplified by PCR with genomic DNA used as templates from 20 healthy persons and 32 patients with dominantly allergic familial history living in the north of china.Then separating the amplification with capillary electrophoresis followed by hybridization of molecular beacons into the PCR product which were sequenced in the end. Results Detected with CE-MB method,there was significant difference in the distribution of A/G in IL-13exon 2044,A allele frequency was higher in asthma compared with normal controls,same as sequencing. Conclusion The method of capillary electrophoresis based on molecular beacon(MB-CE) is able to be developed as a clinical detecting method for genetic variation diseases.IL-13 A2044G SNP is important in the asthmatic mechanism.

Objective To investigate the regulation expression of leukemia inhibitory factor(LIF)in hu- man and animal osteoarthritic(OA)tissues and its clinical relevance.Methods 1)Thirty-five Japanese rabbits, aged eight months,were used to make models of experimental osteoarthritis.Operations were performed at the right knee and the sham ones at the left knee in each rabbit.Rabbits were sacrificed on the 3,7,14,28,42,56 and 84 days after operation respectively.Cartilage and synovium of the knee were collected to observe histological changes of osteoarthritis at different times;immunohistochemistry analysis was conducted to observe the LIF expression and distribution in the cartilage and synovium of the animals.2)From April 2003 to October 2003,32 samples of human articular tissues(cartilage,subchondral bone and synovium)were obtained in the operational procedures and a good quantity of RNA was isolated using Magnetic Beads.The patients who underwent articular operations donated the samples.In the reverse transcription-polymerase chain reaction(RT-PCR),the mRNA expression of LIF was mea- sured by semi-quantity analysis and the location of LIF protein was determined by enzyme-linked immunosorbent assay (ELISA).Results A slight expression of LIF was seen in normal cartilage but less in synovium.However,the expression of LIF was remarkable in synovial lining cells,superficial and middle layers of cartilage in animal os- teoarthritis.There was a significant difference in expression between the animal osteoarthritis and the control group (P＜0.05 ).In human tissue study,LIF mRNA was expressed to a very low level in normal articular tissues and there was no significant difference(P＞0.05)between different anatomical locations.In moderate degrading sub- chondral bone,LIF mRNA was expressed to its highest level.LIF was expressed to the highest level in seriously degrading cartilage tissues.The results were similar to ELISA testing results.LIF extents varied in different articular tissue sections.Conclusions LIF is an important mediator that can contribute to tbe pathogenesis of OA.The different temporal and spatial distributions of LIF in normal and OA tissues imply that LIF may play some important roles in pathogenesis of OA.

Objective To evaluate the feasibility and safety of endoscopic intraluminal closure of small colon perforation with metal clips in porcine model.Methods A 2 cm full-thickness colon perforation was made in 4 bama mini-pigs.One did not receive local closure as a control, while 3 others underwent closure with bi-and tri-arm clips, one of which received additional fibrin glue injection after closure.Necropsy was done on day 14 after the procedure, and dye leak test, peritoneal fluid bacteria culture and histological examination were performed.During the 2 week observation period, the body temperature and blood leukocytes count were recorded and compared.Results Endoscopic closure of the colon perforation was technically successful in all 3 pigs.The body temperature and blood leukocyte count of these pigs were both lower than those of the control.Necropsy showed that the perforation in control pig was not completely closed and with multiple adhesions around.Perforation complete closure and pathological healing without adhesion were observed in 2 pigs with clip closure only, while adhesion and incomplete pathological healing was detected in the other one with clip closure plus fibrinogen injection (P＜0.05).Conclusion Endoscopic intraluminal closure of a 2 cm colon perforation with metal clips is feasible and safe, while further study is needed to evaluate the effect of combined local fibrinogen injection.

Objective To observe the action of narcotrend monitoring for perioperative anesthesia management in donor and acceptor with living donor renal transplantation. Methods 80 pairs of receptor and donor haing electie living donor renal transplantation surgery, 28 ~ 56 years. The ASA of receptor Ⅲ ~ Ⅳ, and the donerⅠ ~ Ⅱ. The receptor and donor were randomly divided into four groups , the narcotrend monitoring receptor group (R-N), the clinical experience receptor group (R-C), the narcotrend monitoring donor group (D-N), and the clinical experience donor group (D-C). Record the vital signs, the last time of anesthesia induction, operation , extract the endotracheal catheter , and the observation time in post anesthesia care unit , the dosage of propofol and dopamine, the adverse reaction, and postoperative visual analogue scale. Results The dosage of propofol in R-N group is less then the R-C group (P < 0.05). The time of extract the endotracheal catheter,and the observation time in post anesthesia care unit in R-N group was shorter then the R-C group (P < 0.05). No statistical differences between the D-N group and D-C group. Conclusions Narcotrend monitoring can significantly reduce the dosage of propofol , the observation time in post anesthesia care unit , and the postoperative adverse reactions. But there is little effect to the donor.

Objective To study the SRSF2 mutations in acute myeloid leukemia (AML) patients by using high-resolution melting analysis (HRMA). Methods PCR-HRMA analysis was performed to screen SRSF2 mutations in 140 cases with AML, and the direct DNA sequencing was used to confirm the HRMA results. Results Five percent (7/140) of AML patients were found with heterozygous SRSF2 mutations, including one case of P95R mutation, two case of P95L mutation, and four cases of P95H mutation, the above mutations were confirmed by direct DNA sequencing. The maximal sensitivity of HRMA in detecting SRSF2 mutation was close to 10%. There were no difference in gender, age and blood parameters among cases with or without SRSF2 mutations (P > 0.05). The overall survival (OS) of patients with SRSF2 mutations was inferior to those without SRSF2 mutations in AML patients (P=0.016). Conclusions HRMA analysis was a convenient, rapid, specific, high-throughput technique for scanning of SRSF2 gene mutations in AML patients. SRSF2 mutation may predict the adverse prognosis in AML patients.
