AIM: To investigate the role of fatty acid translocase/CD36 (FAT/CD36) in adipose tissue in-flammation induced by a high-fat diet.METHODS:C57BL/6J mice were fed with a normal-chow diet ( NCD) or a high-fat diet ( HFD) for 14 weeks.The content of free fatty acid ( FFA) in the serum was measured by ELISA.The expression of CD36, cytokines and chemokines at mRNA and protein levels in the adipose tissues was determined by real-time poly-merase chain reaction and Western blotting.Immunohistochemical staining was used to examine the macrophages infiltration in the adipose tissues.The inflammatory responses in CD36 knockout mice and wild type mice with high-fat diet were ana-lyzed.RESULTS:The levels of FAT/CD36 were higher in HFD group than that in NCD group.HFD feeding enhanced the mRNA and protein expression of IL-1β, IL-6, TNF-α, MCP-1 and MIP-1, as well as promoted macrophage infiltration in the adipose tissues.Interestingly, as fed with HFD, the expression of cytokines/chemokines and macrophage infiltration were significantly reduced in adipose tissues of the CD36 knockout mice, compared with the wild type mice.CONCLU-SION:High-fat diet promotes adipose tissue inflammation in the mice in a FAT/CD36-dependent manner.

Objective:In order to improve the treatment methods of laryngotracheal atresia, several improved surgical procedures were used.Method:From 1986,the 48 patients with laryngotracheal atresia accepted surgical treatment in our hospital.Laryngo-fissure with laser cauterization of the glottis, laryngotracheal reconstruction using surgical flaps with or without particles, laryngo-tracheal reconstruction using itself′s cicatrices, tracheal end-to-end anastomosis, two-stage laryngotracheal reconstruction using aqueduct method, bronchotracheal reconstruction through the chest. Result:46/48 cases were cured breathing without tracheal cannula.Following-up survey is 1～12 years.Conclusion:The treatment of cicatriceal laryngotracheal atresia was difficult, but if the surgical methods were selected carefully according to the situation of each patient, we also can get a good result.

Objective To evalue the ability of detecting the resistance of cefoxitin-sensitive,penicillin-resistant Staphylococcus by different methods and analyze the antibiotic susceptibility spectrum of coagulase-negative Staphylococcus which are non-mecA-mediated oxacillin resistance. Methods All the isolates were collected from Huashan hospital between 2007 and 2009. The isolates were recovered from various clinical sources, including respiratory tract, urine, secretion and sterile fluids samples. The oxacillin susceptibility of Staphylococcus aureus was determined by cefoxitin disk diffusion test, cefoxitin MIC test,oxacillin disk diffusion test and oxacillin MIC test Likewise, the oxacillin susceptibility of coagulasenegative Staphylococcus was determined by cefoxitin disk diffusion test and oxacillin MIC test. All the isolates with sensitive to cefoxitin were screened for the mec A gene by PCR Finally, the MIC of non-mecA-mediated oxacillin-resistant Staphylococcus were determined. Results Among 255 cefoxitin disk diffusion test sensitive and penicillin-resistant Staphylococcus aureus, 6 isolates were intermediated to oxacillin and 4 were resistant by oxacillin disk diffusion test, but all the isolates were sensitive by the cefoxitin disk diffusion test,cefoxitin MIC test and oxacillin MIC test. Among 75 cefoxitin disk diffusion test sensitive and penicillin-resistant coagulase-negative Staphylococcus, 16 isolates were resistant to oxacillin by oxacillin MIC method and 4 carried mecA gene. Among 12 non-mecA-mediated oxacillin-resistant Staphylococcus, the susceptible isolates of gentamicin is 10, clindamycin is 8, ciprofloxacin is 11, erythrornycin is 6, trimethoprim/sulfamethoxazo]e is 11 ,and cephalosporins, teicoplaninl, vancomycin, piperacillin/tazobactam, tetracycline are all 12. Conclusions The cefoxitin disk diffusion test can reliably predict mecA-mediated oxacillin resistant Staphylococcus aureus. It would be best to combine cefoxitin disk diffusion test and oxacillin MIC test to improve accuracy of detection of mecA-mediated oxacillin resistant coagulase-negative Staphylococcus.Furthermore, infections due to the non-mecA-mediated oxacillin resistant coagulase-negative Staphylococcus can be treated by penicillinase-stable penicillins, β-lactam/β-lactam inhibitor combinations, relevant cephems and carbapenems.

OBJECTIVE To investigate the clinical characteristics,treatment and prognosis of laryngotracheal stenosis due to relapsing polychondritis (RP).METHODS The clinical data of 6 patients with laryngotracheal stenosis due to RP were reviewed retrospectively.RESULTS From 1996 to 2006,6 patients with laryngotracheal stenosis due to RP were managed in our hospital.Respiratory tract lesions were diffuse and extensive.Of them,4 patients accepted laryngotracheal reconstruction using surgical flaps with or without pedicle,2 accepted dilation of trachea in thoracic segments.Five patients were cured without recurrence.CONCLUSION Treatment of laryngotracheal stenosis due to RP is very difficult.If the surgical opportunity and methods were selected correctly according to each patient,good results can also be obtained.

Under the background of dual-track training mode, the current clinical program of professional master's graduate education lacks complete and unified content and requirements. We set out a unified teaching scheme of subspecialty, in the main subject acupuncture. We identified the teaching management and innovated the teaching and examination methods in the scheme. Our research gradually formed a multidisciplinary talents training system, as the foundation of developing the standardization training. This method could help to cultivate qualified graduates as the high quality talents for the national medicine development.

Objective To investigate whether methamphetamine (METH) can enhance human immunodeficiency virus 1 (HIV-1) infection in macrophages and the possible mechanism.Methods Peripheral blood samples were collected from eight healthy adult donors.Monocytes were isolated from blood samples and then cultured in vitro to induce differentiation to macrophages.These macrophages were treated with METH and/or dopamine receptor D1 (DRD1) antagonist,and then infected with HIV Bal strains.The levels of HIV RNA were measured in HIV Bal-infected macrophages by RT-PCR analysis.The real-time RTPCR was performed for the quantification of cellular DRD1.Results METH promoted HIV replication in macrophages in a dose and time dependent manner.This METH-mediated enhancement of HIV infection and replication in macrophages could be blocked by the DRD1 antagonist (SCH23390).Moreover,METH could induce the expression of DRD1.Conclusion METH might play a co-factor role in HIV infection in human macrophages by up-regulating the expression of DRD1.

T,P=0.008; Genotype:P=0.031)of DISC1 gene were significantly associated with schizophrenia.The haplotypes constructed by these two markers were significantly associated with schizophrenia,such as AT(?2=7.065,P=0.008,OR=1.42,95%CI=1.10~1.83)and GA(?2=6.009,P=0.014,OR=0.80,95%CI=0.68~0.96).When the subjects examined with the positive and negative syndrome scale(PANSS),the risk haplotype AT was not significantly correlated with positive,negative,excitement,depression and cognitive impairment factors of PANSS. Conclusion:These findings provide further evidence for DISC1 as a predisposing gene involved in schizophrenia in the Chinese Han Population.However,no positive association is found between DISC1 polymorphisms with schizophrenia clinical symptoms.

A total of 60 non-acupuncture master postgraduates were divided into control class and experimental class randomly, 30 postgraduates in each class. The control class was taught by traditional teaching methods and experimental class was taught by new teaching methods. The test was conducted after one month later. All the scores were analyzed by SPSS17.0. The result showed that the oretical score ,the practical score and disease recognition rates in the experimental class were significantly higher than those in the control class (P<0.05). The questionnaires showed experimental class had obvious advantage than control class (P<0.05). The new teaching methods of acupuncture has obvious advantage than traditional teaching methods and can provide a new way for teaching acupuncture during resident standardization training.

Objective To detect chromosomal aberrations of autism spectrum disorder (ASD), we performed karyo?types analyses in 632 ASD trios and then investigated whether copy number variants and neurodevelopment related genes are present in the regions of chromosomal aberrations. Methods Karyotypes analyses were performed in 632 ASD trios (1896 individuals). In addition, we investigated whether there were pathogenic copy number variants located in the rele?vant regions of detected aberrant karyotypes by using the database of the International Standards for Cytogenomic Arrays (ISCA) and the Genomic Variation and Phenotype in Humans using Ensembl Resources (DECIPHER) for ASD patients. Results We detected aberrant results in 22 of 632 patients (3.48%) by karyotypes analyses. Of these 22 aberrant karyo?types, 5 were de novo (0.79%), including the duplication, the translocation, karyotypes of Turner syndrome and the addi?tional material with unknown origin. Seventeen children affected with autism had aberrant karyotypes inherited from one of their parents. By using the ISCA and the DECIPHER database, we found that several copy number variants with high pathogenicity were located in 1q25 and 3p24. Further, these copy number variants consisted of several genes related to neurodevelopment such as TNR, ASTN1, and NMNAT2. Conclusion There are a few de novo chromosomal aberrations in some patients affected with ASD. Copy number variants of several pathogenic neurodevelopmental related genes may exist in the regions of chromosomal aberrations. Karyotypes analyses may be applied to explore the genetic etiology in some patients affected with ASD.
