Objective To explore the role and mechanisms of ω-3 polyunsaturated fatty acids (ω-3PUFA) alone or in combination with dexamethasone ( DEX) in inducing cell apoptosis and anti -proliferation in multiple myeloma(MM).Methods DEX resistance MM cell line MM1R were treated with different concentra-tions of Eicosapentaenoic acid(EPA)or Docosahexaenoic acid(DHA)alone or in combination with DEX for 24hrs or 48hrs.Cell proliferation was detected by MTT .Cell cycle and apoptosis were measured by flow cytometry .The levels of apoptosis related proteins were analyzed by Western blot .Results The proliferation of MM1R was in-hibited by different concentrations (10,20,50,100μM)of EPA or DHA alone or in combination with 10μM DEX in a dose-and time-dependent manner .Inhibition effect was significantly higher in combinative groups than in single agent groups(P<0.05).The percentage of G0/G1 phase and cell apoptosis rate in MM1R treated with dif-ferent concentrations of EPA or DHA alone was increased in a dose -dependent manner ,and being significantly higher in combinative groups than in single agent groups (P<0.05).The expressive levels of cleaved caspase -3 and Bax were up-regulated ,while pro-caspase-3 and BCL-2 were down-regulated in a dose-dependent manner.Conclusion ω-3PUFA can inhibit DEX resistant MM cell proliferation ,arrest cell cycle and induce cell apoptosis ,and has a synergistic anti -resistant effect in combination with DEX ,may serve as a new ,effective MM drugs.

Objective To investigate the effect of small dose of dexmedetomidine on the development of postoperative nausea and vomiting in the patients undergoing laparoscopic gynecologic surgery.Methods A total of 207 patients,aged 18-60 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective laparoscopic gynecologic surgery under general anesthesia,were randomly divided into either dexmedetomidine group (group D,n=103) or control group (group C,n=104) using a random number table.Before induction of anesthesia,dexmedetomidine 0.1 μg/kg was injected intravenously over 1 min in group D,while the equal volume of normal saline was given instead in group C.At 20 min before the end of surgery,dexmedetomidine 0.04 μg/kg was injected intravenously over 30 s in group D.For the patients requiring patient-controlled analgesia (PCA),PCA solution contained sufentanil 125 μg in 125 ml of normal saline.The PCA pump was set up with a 2 ml bolus dose,a 8 min lockout interval and background infusion at a rate of 1 ml/h.Pethidine was used for PCA after surgery in the patients who did not require PCA.Numeric rating scale scores were maintained ＜4 after surgery.Sufentanil 3 μg was injected intravenously as rescue analgesic in postanaesthesia care unit (PACU).The occurrence of nausea and vomiting was recorded within 0-1 h,1-6 h,6-12 h,and 12-24 h periods after surgery.The occurrence of hypotension and bradycardia during surgery,emergence time,Ramsay sedation score on admission to PACU,requirement for sufentanil as rescue analgesic in PACU,requirement for PCA and antiemetics,and occurrence of somnolence and shivering were recorded.Results Pethidine was not given in the patients who did not require PCA in the two groups.Somnolence and shivering were not found in the two groups.Compared with group C,the incidence of bradycardia was significantly increased,the requirement for antiemetics in PACU and incidence of nausea and vomiting within 1 h after surgery were significantly decreased (P＜0.05),and no significant change was found in the emergence time,Ramsay sedation score,requirement for sufentanil as rescue analgesic,requirement for PCA and total incidence of postsurgical nausea and vomiting in group D (P＞0.05).Conclusion For the patients undergoing laparoscopic gynecologic surgery,small dose of dexmedetomedine can only decrease the development of nausea and vomiting in the early postsurgical period (in PACU),and does not influence the recovery from anesthesia.

Objective To introduce the outcomes of tracheal resection combined with primary end-to-end anastomosis for benign cervical tracheal stenosis,and to discuss the strategy for prevention of surgical complications.Methods The clinical data of 22 patients due to different causes benign cervical tracheal stenosis surgery were analyzed retrospectively.Results The length of cervical tracheal stenosis ranged was 2.2-4.2 cm.Grade Ⅱ stenosis was present in 6 patients.Grade Ⅲ stenosis was present in 11 patients and grade Ⅳ stenosis in 5 patients.Successful extubation was achieved in all 22 cases.After surgery,temporary hoarseness occurred to 1 case;unilateral pulmonary atelectasis with pleural effusion occurred to 1 case; subcutaneous emphysema with infection occurred to 1 case; mild dysphagia occurred to 3 cases;a slight deepening of the tone of voice in 10 patients with women occurred to 5 cases,granulation tissue growth near the suture occurred to 3 cases,and suture dehiscence did not occur in any patient.The follow-up period ranged from 6-45 months,no patient developed restenosis.Conclusions It presents a high success rate and good functional result of tracheal resection combined with primary end-to-end anastomosis.Therefore,it is an effective and reliable approach for the management of benign cervical tracheal stenosis.To avoid complications,the preoperative assessment,patients selection and postoperative management should be emphasized.

BACKGROUND: Acellular dermalmatrix (ADM), as a new material, is generally applied to tissue repair after head and neck tumorectomy. However, hypopharyngeal carcinoma surgery always involves in repair and functional reconstruction of defected tissue; therefore, the application effect of ADM needs to be further studied for repairing laryngopharynx defect. OBJECTIVE: To evaluate the clinical effect of ADM in repairing laryngopharynx defect following tumorectomy. DESIGN, TIME AND SETTING: A retrospective case analysis was performed at the Department of Otolaryngology-Head and Neck Surgery, Institute of Battle Surgery, Daping Hospital, the Third Military Medical University of Chinese PLA from May 2005 to June 2006.PATICIPANTS: A total of 25 male cases aged 45-68 years including 22 patients with tumor in the lateral wall of the unilateral piriform fossa and 3 patients with in the posterior wall of laryngopharynxat were finally diagnosed as squamous cell carcinoma. METHODS: According to clinical stages, patients underwent partial or complete laryngopharyngectomy. ADM was used to repair oropharynx mucosa following the laryngopharyngectomy. However, ADM alone was used to repair piece-shaped oropharynx mucosa, limiting by being unable to complete reconstruction of spatial structure. Therefore, myocutaneous flap or other materials combined with ADM was beneficial for reconstruction of laryngopharyngeal cavity following complete laryngopharyngectomy. MAIN OUTCOME MEASURES: The effect of ADM on functional reconstruction of swallowing, breathing, and pronouncing. RESULTS: A total of 25 patients were included in the final analysis. No patients suffered with the pharyngeal fistula. Only one case encountered the subcutaneous infection at day 20 after surgery, but recovering after regular change of dressing and treatment of antibiotics. About 15 patients who accepted the surgery of partial laryngopharyngectomy suffered with bucking, but after 30-60 days, the symptom relieved, even disappeared, in spite of 3 cases still bucking when they swallowed liquid diet. Breathing function was recovered, and tracheal cannula was removed 6-12 months after surgery. Ten of them who accepted total laryngopharyngectomy had resumption of normal oral diet after 20 days. The follow-up periods after the surgery lasted 12-30 months. The allograft became normal mucosa finally, without rejection or scar formation. The follow-up of 10 patients lasted more than 24 months, one case had relapse of tumor, still alive after the second surgery. CONCLUSION: ADM with perfect histocompatibility and easy operability, can be applied to repair deletion of laryngeal or pharyngeal tissue and recover functions of pronouncing, breathing, and swallowing after tumorectomy. The combined use of ADM and musculo-cutaneous flap was effective and satisfactory.

Objective: To develop novel targeted anticancer medicines for effective treatment of nasopharyngeal carcinoma ( NPC) , a prevalent malignant disease in southern China and southeast Asia.Methods: CNE cells were treated with a novel indolinone IF239 synthesized by our research group. Cell viability was determined by the acid phosphatase assay ( APA). Morphologic changes and adhesion status of CNE cells treated with IF239 were observed under a light microscope. Flow cytometry was used to analyze the cell cycle phases . Key regulating molecules in the cell cycle progression were detected by Western blotting. Results: IF239 had potent cytotoxic effect on CNE cells. The possible antitumor mechanisms of IF239 involved inhibition of cell adhesion and cell cycle arrest in the G2_/M phase. Moreover,G2_/M arrest caused by IF239 was related to up-regulation of both cyclin B1 and the phosphorylation level of CDK1. Conclusion: IF239 has high anticancer activity over CNE cells, and has unique anticancer mechanisms, suggesting that IF239 has promising application potentials.

Since 2007, a number of published population-based studies have shown that stroke epidemiology has changed. There are some differences in morbidity, mortality, risk factors and clinical prognosis of stroke between the high-income countries and the less developed countries.

Objective To investigate whether the gamma-aminobutyric acid (GABAB) receptor genes,including gabbr1 gene and gabbr2 gene,are the susceptible genes for simple febrile seizures (sFS) by screening mutation of gabbr1 gene and gabbr2 gene and to study the possible association between sFS and the 2 genes.Methods All exons and flanking introns of gabbr1 gene and gabbr2 gene were amplified with polymerase chain reaction (PCR) and sequenced to screen the possible mutation on 60 children with sFS in the northern China in Han nationality population.One hundred and one healthy children from the same area were selected as controls,and the genotypes of single nucleotiole polymorphisms (SNPS) (rs29220,rs29230,rs29267 on gabbr1 gene and rs1000440,rs3205936,rs2304391 on gabbr2 gene) were typed by PCR-restriction fragment length polymorphism.EH1.20 software was used to estimate haplotype frequency to study the association with the haplotype as genetic marker between case group and control group.Results No mutation associated with sFS was found in the 60 sFS cases.In all sequenced regions,23 SNPs were identified in both genes:6 SNPs in gabbr1 gene and 17 SNPs in gabbr2 gene.The frequencies of the 6 SNPs were complied well with the Hardy-weinberg equilibrium in sFS group and normal group.Genotype proportions and allele frequencies of 6 SNPs were not significantly different between both groups.The haplotypes of 3 SNPs in gabbr1 gene and in gabbr2 gene distributions were not significantly different between 2 groups.Conclusions No mutations and associations were identified between sFS with both GABAB receptor genes(gabbr1 gene and gabbr2 gene).They may not be the susceptibility gene for simple febrile seizures in Han nationality population in northern China.
