Objective To investigate the loss of heterozygosity at 17 microsatellites of 10 chromosome arms in 68 resected specimens of esophageal cancer, and the relationship to the clinicopathological phenotypes of patients. Methods 68 tumor specimens (20 well-differentiated squamous carcinomas, 30 moderately differentiated carcinomas and 18 poorly differentiated carcinomas) and their matched blood samples were analyzed for LOH at 17 microsatellites by using PCR and fluorescence-based DNA sequencing technology, and the association of LOH with the clinicopathological phenotypes of patients was compared statistically. Results The lowest detection frequency of LOH in our subjects was observed at D8S261 with 33. 3%, and the highest frequency was at D9S125 with 85. 2%. There were 12 markers with the frequency of LOH higher than 50.0%, and 3 markers (D3S1597, D3S1285 and D9S125) with the frequency higher than 75. 0%. There was a significant difference in the frequency of LOH at D9S111 and D13S153 between tumors with different histological grades. LOH at D9S111 was observed in 2 of 12 tumors with well differentiation in 14 of 20 tumors with moderate differentiation, and in 14 of 16 tumors with poor differentiation. LOH at DI3S153 was observed in 2 of 8 tumors with well differentiation, in 12 of 28 tumors with moderate differentiation, and in 11 of 12 tumors with poor differentiation. There was a significant difference in the frequency of LOH at D8S261 between tumors with lymph node metastasis and without lymph node metastasis. LOH at D8S261 was found in 1 of 14 tumors with lymph node metastasis, and in 12 of 22 tumors without lymph node metastasis. Conclusions The widespread and frequent loss of heterozygosity may exist in esophageal cancer, and the candidate genes located in the site of frequent LOH may be involved in the development of this cancer; LOH at D9S11 and D13S153 are more commonly observed in the patients with higher histological grades, the tumors with LOH at D8S261 may have a low tendency to lymph node involvement.

Objective:To evaluate the efficacy of remimazolam-propofol-sufentanil for anesthesia in patients undergoing painless gastroscopy.Methods:Eighty American Society of Anesthesiologists physical statusⅠor Ⅱ patients, aged 20-59 yr, weighing 44-69 kg, scheduled for elective painless gastroscopy, were divided into 2 groups ( n=40 each) using a random number table method: remimazolam-propofol-sufentanil group (group RPS) and propofol-sufentanil group (group PS). The patients in group RPS received successive intravenous injection of sufentanil 0.1 μg/kg, remimazolam 0.15 mg/kg and propofol (at a rate of 4 mg/s). The patients in group PS received intravenous injection of sufentanil 0.1 μg/kg and propofol (at a rate of 4 mg/s). When Observer′ s Assessment of Alertness/Sedation Scale score was 0, gastroscopy was performed.The consumption of propofol, time of anesthesia, time for gastroscopy, emergence time and discharge time were recorded.The number of intraoperative assisted respiration cases, body movement and occurrence of adverse reactions at the time of discharge were observed. Results:Compared with group PS, the consumption of propofol was significantly decreased, and the time of anesthesia, emergence time and discharge time were shortened in group RPS ( P<0.05). There was no significant difference in the time for gastroscopy, the number of intraoperative assisted respiration cases, body movement and the occurrence of adverse reactions at discharge time between the 2 groups ( P>0.05). Conclusion:Remimazolam-propofol-sufentanil produces better efficacy for anesthesia than propofol-sufentanil in patients undergoing painless gastroscopy.

Objective To investigate the relationship between spinal neuronal microRNA 212 (miR-212) and phosphorylation of cAMP response element-binding protein (CREB) in a mouse model of bone cancer pain (BCP).Methods Thirty-two male SPF C3H/HeJ mice, aged 4-6 weeks, weighing 20-25 g, were randomly divided into 4 groups (n=8 each) using a random number table: sham operation group (group S), BCP group, BCP + intrathecal negative control locked nucleic acid (LNA) group (group BC) , and BCP + intrathecal miR-212 antisense LNA group (group BL).After the mice were anesthetized with intraperitoneal pentobarbital sodium, 20 μl of α minimal essential medium containing NCTC 2472 cells 2×105 was injected directly into the medullary cavity of the distal femur.In BC and BL groups, negative control LNA and miR-212 antisense LNA 12 pmol/5 μl were intrathecally injected, respectively, once a day for 7 consecutive days, starting from day 14 after inoculation.In S and BCP groups, the equal volume of DNAse/RNAse-free water was given instead.The number of spontaneous flinches (NSF) and mechanical paw withdrawal threshold (MWT) were measured on 1 day before inoculation and 4, 7, 10, 14 and 21 days after inoculation.The mice of each group were sacrificed after measurement of pain threshold on 21 days after inoculation, and the lumbar enlargement segments of the spinal cord were harvested to detect the expression of phosphorylated CREB (p-CREB) and CREB using Western blot.Results Compared with group S, the MWT was significantly decreased, and the NSF was increased on 7-21 days after inoculation, and the expression of p-CREB was up-regulated in BCP, BC and BL groups.Compared with group BCP, the MWT was significantly increased, and the NSF was decreased on 21 days after inoculation, and the expression of p-CREB was down-regulated in group BL, and no significant change was found in the parameters mentioned above in BC group.There was no significant difference in the expression of CREB between the four groups.Conclusion Spinal neuronal miR-212 is involved in the maintenance of BCP probably by promoting phosphorylation of CREB in mice.

CD127 is the interleukin7 receptor ?(IL7R?),it regulates the specific respond of T lymphocytes to IL7.CD127 plays an indispensable role in the development of thymocytes into T lymphocytes,the survival and homeostatic proliferation of memory T cells.There are only two phases of the life period of T cells that do not express CD127:immature CD4+8+double positive(DP)thymocytes and activated T cells.Recently,it was found that CD127 play an important role as the specific marker of memory T cells and regulator T cells.The role and mechanism of CD127 in the life period of T cells were discussed herein.

Using uniform design to optimize some relative factors influencing the expressing of t-PA variant-rPA(K) in E.coli system, and found the best expressive conditions. They were(by using 300ml culture fask): the volume of media was 25ml, inducing time was 5.3 hours, pH was 6.0, the concentration of IPTG was 0.1mmol/L, inducing time was 25℃, and best culture media was HD. After being optimized, the yield of expression had been improved from 0.16 to 0.48, and it was as 3 times as before. The results above will offer the basement for purification and renaturation of rPA(K).

In order to study the regularity of shedding virus from infected SPF chickens and the formation of aerosol of H9N2 subtype AIV, SPF chickens were bred in a positive and negative pressure isolator. Aerosol samples were collected by AGI-30 (All Glass Impinger-30) extractor, and simultaneously trachea and cloaca samples were collected by tracheal swabs and cloacal swabs in different periods after challenged with vi- ruses. The above-mentioned samples were detected by HI, Dot-ELISA and RT-PCR methods. The results in- dicated that aerosols were isolated from the 4 days to the 43 days after inoculation. It was proved that H9N2 subtype AIV could copy themselves in respiratory passage and cloaca, and then could formation of aerosols. AIV H9N2 subtype could be isolated from cloacal and tracheal swabs 3 days after inoculation and lasted for 45 days, viruses were detected from all infected SPF chickens on 7 days.

The skin ulceration syndrome of sea cucumber is a kind of desease induced by bacterium.In order to investigate the bacterium of infected sea cucumber and detect the N-acyl-homoserine lactones(AHLs) se-cretion of the bacterium,7 bacterial strains were isolated from the infected sea cucumber.These strains were identified by physiological-biochemical characteristics and 16S rDNA sequence.Results show that strain C6 belongs to Tenacibaculum,strain 4 belongs to Shewanella putrefaciens group,strain TB belongs to Vibrio,strain BP2,BP3,BP4 and BP6 belong to Pseudoalteromonas,respectively.AHLs were detected with strain Agrobacterium tumefaciens KYC55.Among these bacterial strains,strain C6,4,TB,BP3 and BP4 can se-cret AHLs,while strain BP2 and BP6 can’t.And the AHLs activity differs,from the highest to the lowest are 4,TB,BP4,BP3 and C6.
