OBJECTIVE To investigate the feasibility of endoscopic sinus surgery under local anesthesia.METHODS A total of 810 patients underwent endoscopic sinus surgery from January 2000 to December 2007 with complete follow-up data were included in this study.Validity of anesthesia was evaluated using VAS(visual analogous scale).Operation time,bleeding quantity during operation,operation therapeutic efficacy,hospitalization cost and patient's evaluation to the operation were recorded.RESULTS The mean VAS score of local anesthesia was 3.18?0.46.Cases with no pain and mild pain accounted for 78.28%,with moderate pain 16.71%,and with severe pain 5.01%.The average bleeding quantity during operation,operation time,complication incidence,cure rate at 6 months after operation,hospitalization cost,patients' evaluation in local anesthesia were(43.25?27.46)ml,(41.14?9.479) min,1.78%,78%,4000～6000 yuan(RMB),9.28? 2.21 respectively.CONCLUSION For the endoscopic sinus surgery,most cases can be operated under local anesthesia if the indication were selected correctly and the sophisticated skills and advanced instrument were available.

Macrophages play an important role in the pathogenesis of many diseases because of its plasticity and diversity.The Notch signaling pathway is a key regulator of the biological function of macrophage and has a complex network connection with many other signaling pathways.This paper reviews the conduction of Notch signaling pathway and its regulation on the polarization of macro-phages.

Aim To investigate the effect of ginsen-oside metabolite compound K ( CK) on migration and invasion of human hepatocellular carcinoma line HepG2, and the possible signaling pathway underlying these processes .Methods HepG2 cells were exposed to ginsenoside CK (0, 10, 20, 40, 80 μmol· L-1 ) for 24 h.The cell viability was examined by MTT as-say, and the ability of migration and invasion was ob-served with the wound healing and transwell assay .The expression of E-cadherin , N-cadherin and other related signal molecules such as p-ERK, ERK, p-Akt, Akt were detected by Western blot .Results The cell via-bility was significantly reduced by ginsenoside CK (20, 40, 80 μmol· L-1) (P<0.01).The ability of cell migration and invasion was significantly inhibited after exposure to ginsenoside CK .After treatment with ginsenoside CK (20, 40, 80 μmol · L-1 ) in HepG2 cells, the expression of E-cadherin markedly in-creased, while N-cadherin expression significantly de-creased.Meanwhile, the expression of p-ERK and p-Akt decreased after treated with ginsenoside CK .Con-clusion Ginsenoside CK inhibits the migration and invasion of human hepatocellular carcinoma line HepG2, which may be through suppression of ERK and Akt signaling .

Aim To observe the variation of T-cell subsets in spleen in different courses of disease and tis-sue histopathological changes in rats with adjuvant ar-thritis (AA).Methods The model of rat AA was in-duced by complete Freund’s adjuvant into the right hind metatarsal footpad of 20 male Lewis rats.Arthritis was evaluated by total score,arthritis index and paw swelling number. The percentage of total (CD3 +CD4 +), memory (CD4 + CD44 +), no-sensitizated (CD4 + CD62L +) and Th1 7 (CD4 + IL-1 7 +) on CD4 +T cells in spleen were detected by flow cytometry on days 1 4 and 22 after immuniozation.The his-topathological evaluation of heart,liver,spleen,lung, kidney,ankle joints and mesenteric lymph nodes were examined by hematoxylin and eosin (HE)stain.Re-sults The onset of secondary arthritis appeared on a-bout day 1 0 after immunization,with a peak onset on day 1 9.Systematic arthritis symptoms included front and hind paw swelling and redness (swelling was more apparent in the front rather than hind paws),nodule formation and redness on the ears,connective tissue swelling and redness of the nose and evident nodules and redness on the tail.Total score,arthritis index and the paw swelling numbers were enhanced in AA rats. Pathohistology of ankles joints showed hyperplasia, pannus formation,and inflammatory cells infiltration in AA rats.And pathohistology of heart,liver,spleen, kidney and mesenteric lymph nodes showed inflamma-tory changes.Compared with normal group,there was no change in the percentage of total,memory and no-sensitizated CD4 +T cell in the early stage inflammation but they were significantly enhanced in the peak of in-flammation.Th1 7 cell subsets were significantly en-hanced in both of the early and peak of inflammation. Conclusion These findings suggest that abnormal T cell responses and tissue histopathological changes are important features of AA rats.

Objective To investigate the proliferation rule after autografl vein in autografl of vein and repairing arterial defect,discuss the minuteness structure changes related to time,and provide morphological date for the prevention and treatment of restenosis in clinic application.Methods Sixty canine femoral veins (3.5 cm and 5.5 cm) were excised,reversed and grafted to repairing femoral arterial defect using end- to-end anastomosis.During the period of 30-180 days excised the grafted veins,observed ultrastrural changes of endothelium,microstructural components relative content and patency in grafted veins through angiography, lipht microscope.Results Angiography show that the grafted vein wall get gradually thicker,vascular cavity get slender,and vessel elasticity shrinkage.Light microscope chalrify the ultrastructural changes of endotheh- um,the three lamine structure of grafted vascular wall could not be identified.Conclusion Grafted femoral veins had obviously arteriosclerosis trend after it was transplanted to the arterial system.Two months after the transplantation is the crisis time of the proliferation of the vascular wall.The effect of the proliferation of the grafted veins vascular wall and the impact of the hi-pressure of blood can lead some canine ruptured to die from pseudoaneurysms.

Nine pediatric patients (4 females,5 males) with huge hemangioma of head and neck complicated with Kasabach-Merritt phenomenon,aged 15-135 days,undergoing elective radical resection for huge hemangioma of head and neck,were selected from June 2012 to June 2016 in our hospital.Two pediatric patients were sensitive to preoperative hormone treatment,the platelet count almost increased to the normal value,7 pediatric patients were not sensitive to preoperative hormone treatment,and the increase in platelet count was not obvious.When the platelet count ＜ 40× 109/L,platelet was infused at 12 h before operation until the platelet count ＞ 100× 109/L.Two pediatric patients with larger haemangioma in maxillofacial region kept spontaneous breathing,and anesthesia was induced by inhaling high-concentration of sevoflurane.Anesthesia was induced with intravenous midazolam,sufentanil and cisatracurium in the other seven pediatric patients.Pediatric patients were mechanically ventilated in pressure-controlled mode after endotracheal intubation with airway pressure of 9-12 cmH2O.All pediatric patients inhaled sevoflurane,and anesthesia was maintained by infusing remifentanil.Heart rate and systolic blood pressure were maintained within the normal range during operation.Fluid and blood products were infused according to the blood loss,urine volume,physiological requirement and central venous pressure,etc.Pediatric patients were transferred to pediatric intensive care unit (PICU) at the end of operation,and the endotracheal tube was removed after the patients were completely awake.One pediatric patient developed pulmonary infection after operation,was discharged from PICU on day 7 after operation,then cured and discharged from hospital after healing on day 20 after operation.The other eight pediatric patients were discharged from PICU on day 2 after operation,then cured and discharged from hospital on days 5-10 after operation.After a followup period of 1 yr,the pediatric patients recovered well,the platelet count was normal,and the tumor recurrence was not found.

OBJECTIVETo analyse the association between polymorphism in human synaptosomal-associated protein of 25 000 (SNAP-25) gene and attention deficit hyperactivity disorder (ADHD) in Han Chinese children.

METHODSThe study samples were comprised of 100 integrated ADHD trios (included proband and biological parents) and 97 unrelated controls. Association of polymorphism with ADHD and its subtype was examined by: (1) comparing cases and controls; (2) using family-based association study in transmission disequilibrium test (TDT).

RESULTSCase-control analysis of short tandem repeat (STR) showed that there was no significant difference between the two groups in allele gene frequency and genotype frequency (P > 0.05); TDT analysis of the rs363006 SNP and the rs362549 SNP revealed no association between SNAP-25 polymorphisms and ADHD (P > 0.05). But after a stratification by ADHD subtype, the rs362549 SNP A allele showed a tendency to preferentially transmitted to ADHD-I subtype (chi(2) = 8.00, P < 0.01); and the rs362549 SNP G allele had a tendency to preferentially transmitted to ADHD-C subtype (chi(2) = 4.122, P < 0.05).

CONCLUSIONSNo association was found between SNAP-25 polymorphisms and ADHD. There was a possible association between rs362549 SNP polymorphism and ADHD subtypes, but the findings require replication before drawing a definitive conclusion.
