The known members of inhibitor of growth (ING) gene family are considered as candidate tumor suppressor genes. ING4, a novel member of ING family, is recently reported to regulate brain tumour angiogenesis through transcriptional repression of NF-?B-responsive genes, induce G2/M arrest by the increased p21 expression in a p53-dependent manner, suppress the loss of contact inhibition and represses activation of the hypoxia inducible factor, which plays an important role in the progression of tumorigenesis. However, seldom studies about ING4 inducing tumor cells apoptosis were reported.The C6 cells (mouse glioma cells) were infected respectively with the blank adenovirus carrying GFP (Ad) and the recombinated Ad-hING4-His, then RT-PCR assay was used to detect the transcriptions of hING4, as well Western-blotting assay was ued to detect the expressions of hING4. The effects of hING4 expression upon C6 cells were observed, and the growth curve was drawed and tumor control rates were calculated. The C6 cells, which were affected by blank Ad and Ad-hING4-His, were respectively observed by LSCM (laser scan confocal microscope) and transmission electron microscope (TEM), detected by flow cytometry; and the genomic DNA of both groups were extracted and electrophoresised in agarose gel to examinate the DNA fragments. The results showed hING4 can significantly inhibit the growth of C6 cells by promoting the cell’s apoptosis, which probably is the first one to prove this property of ING4.The experimental and theoretical foundation for gene therapy for gliomas with ING4 in the future was established.

BACKGROUNDDifficult airway remains not only a challenge to the anesthesiologists, but also a life-threatening event to the patients. Awake intubation is the principal choice to deal with difficult airway, and a key point for awake intubation is airway topical anesthesia. Yet, so far there is no ideal topical anesthesia approach for awake intubation. This study aimed at evaluating the effect of pressure-driven (by 10 L/min oxygen flow) lidocaine spray on airway topical anesthesia in order to find a powerful and convenient method for airway topical anesthesia for conscious sedation intubation.

METHODSThirty adult patients referred for elective surgery under general anesthesia, aged 18 - C60 years and Mallampati class I or II, were recruited for the study. Before topical anesthesia, the observer's assessment of alert and sedation (OAA/S) scale was controlled between 3 and 4 by intravenous midazolam (0.03 mg/kg), propofol (2 mg×kg(-1)×h(-1)) and remifentanil (0.05 µg×kg(-1)×min(-1)). Ten minutes after sedation, topical anesthesia was performed with the pressure-driven lidocaine spray; the driving pressure was achieved by an oxygen flow of 10 L/min. After topical anesthesia, tracheal intubation was performed and the intubation condition was assessed with modified the Erhan's intubation condition score by an experienced anesthesiologist, and a score of less than 10 was considered to be satisfactory. Attempts to intubate the patient were recorded, and the complications such as local anesthetic toxicity, mucosa injury, and respiration depression were also recorded. The mean arterial blood pressure (MAP), heart rate (HR) and pulse oxygen saturation (SpO2) were recorded at different time points before and after intubation. Patients were asked 24 hours after the operation whether they could recall the events during intubation.

RESULTSAll patients were intubated at the first attempt, the average intubation condition score was 7.0 ± 1.1, from 6 to 10, satisfied intubation condition. MAP and HR increased significantly but mildly immediately after the tracheal intubation (P < 0.05), and decreased to the pre-intubation level soon after intubation. There were no related complications and patients had no recall of the intubation procedures.

CONCLUSIONSTopical anesthesia with pressure driven 2% lidocaine spray, where pressure is achieved by 10 L/min oxygen flow, can offer satisfactory intubation conditions for conscious sedation intubation.

BACKGROUND AND OBJECTIVEAmyloid deposition is rare. If there was a great amount of amyloid depositions in the skin tissue, it would be considered to be amyloid deposition disease at first, and then primary cutaneous marginal zone B-cell lymphoma (PCMZL). This study was to analyze the diagnosis and differential diagnosis of two cases of PCMZL with amyloid deposition.

METHODSClinicopathologic characteristics and follow-up of two cases of PCMZL were analyzed. Immunohistochemical staining was performed by EnVision method using antibodies LCA, CD19, CD20, CD79a, CD3, CD7, MUM1, kappa, lambda, Ki-67. IgH and TCRgamma gene rearrangement was detected by polymerase chain reactive (PCR).

RESULTSCase 1, a 71-year-old Chinese male, had a subcutaneous mass on the right elbow that was initially diagnosed with "amyloidosis" in 2004. Three years after the initial diagnosis, he developed recurrences on the right para-auxillary that was still diagnosed with "probably amyloidosis". Four years after the first diagnosis, the patient presented a lesion on the right para-auxillary with a diameter of 2 cm and a lesion on the temporal-parietal dural with a size of 6.0 cmx3.0 cmx3.0 cm. Case 2, a 68-year-old Chinese male, had a subcutaneous mass next to back of the left ear with a size of 9.0 cmx5.0 cm, and he underwent a operation one year previously because of subcutaneous mass in the same site. Microscopically, the tumors of both cases were located in dermis and subcutaneous, tumor cells were medium size with a nodular or diffuse distribution, and some of tumor cells were plasmacytoid/plasma cells. Morphologically, the temporal-parietal dural lesion was similar to subcutaneous lesion and infiltrated into cranial (case 1). Juxtaposed the tumor cells of two cases, there were the large amyloid deposits of amorphous hyaline material and concentrically laminated hyaline spherules in case 1, while cord-like amyloid deposits in case 2. Reactive lymphoid follicles with germinal centers and foreign body giant cells in the stroma were found surrounding the amyloid deposits. Congo red staining showed positive of amyloid deposition in tumor tissues of both cases. Immunohistochemical staining revealed that LCA, CD19, CD20, CD79a and MUM1 expressions were positive in tumor cells, and Ki-67 expression was about 8%-10%. IgL restricted expression as kappa positive while lambda negative was found in both cases. PCR results showed monoclone gene rearrangement of IgH gene in both cases.

CONCLUSIONSOur findings suggest that amyloid deposition rarely present in both primary and metastatic tumors in PCMZL, and its diagnosis should be considered to avoid misdiagnosis. The patients with PCMZL should undergo regular examinations and chemotherapy as well as a long-term follow-up since it is apt to recur or relapse.

OBJECTIVETo investigate the value of 3-dimensional CT in the treatment of developmental dislocation of hip (DDH).

METHODSFrom 2003.6 to 2007.6, the femoral neck anteversion (FNA) and morphology of acetebulum in 53 patients with DDH (61 hips) were studied by three-dimensional CT imaging. Among the patients, 12 patients were male and 41 patients were female, ranging in age from 3 to 16 years (mean 5.6 years). Thirty-four patients had dislocation in left hip joint, 11 patients had dislocation in right hip joints, and 8 patients had double dislocations. The patients were treated with Pemberton or Chiari acetabuloplasty and femoral osteotomy. After operation all the cases were obeserved by 3-dimensional CT again. The femoral neck anteversions were measured and the shapes of new acetabulum were observed.

RESULTSAmong 61 hips of DDH, the maximum femoral neck anteversion was 90 degrees. The minimum was 35 degrees and the average was (45.6 +/- 11.4) degrees. Among 45 normal hips, the average femoral neck anteversion was (23.5 +/- 10. 2) degrees. The acetabulum were dysplastic according with what were found in the operation. After operation the femoral neck anteversions decreased and averaged (15.6 +/- 5.8) degrees. The femoral head containment improved.

CONCLUSIONThe advantages of 3D CT scan includes manifestation of acetebular morphology, correct measurement of femoral neck anteversion and evaluation of operative procedure and efficacy. The 3-dimensional CT method is deserved to use widely in the treatment of developmental dislocation of hip in children.

OBJECTIVE: To establish an acuity inspection system with sweep pattern visual evoked potential (SPVEP) so as to provide the evidence for acuity objective inspection. METHODS: Based on the domestic sweep pattern visual evoked apparatus, sections of hardware were reformed and a manipulation program possessing false random control software was compiled. The SPVEP acuity for the 78 eyes (10 normal eyes, 10 ametropia eyes, 48 prevalence eyes, 10 false ametropia eyes) was estimated with our acuity objective inspection system, then compared with the E visual acuity of those eyes by statistical procedure. RESULTS: There was a close correlation between the SPVEP acuity and E visual acuity for 78 eyes (r2 = 0.946). CONCLUSION SPVEP acuity inspection system can be applied to estimate objective acuity.

OBJECTIVETo investigate the expression and pathobiological implications of angiotensin II type 1 receptor (AT1R) in development of myocardial fibrosis of rats.

METHODSRat myocardial necrosis model was established using isoproterenol injection (15 mg/kg). Rat serum aspartate transaminase (AST), lactate dehydrogenase (LDH), creatine kinase (CK) and creatine kinase isoenzymes (CK-MB) were detected by MD-100 automatic biochemical analyzer. Masson staining was used to evaluate the morphological changes. The expression of AT1R protein was determined by immunohistochemistry and its mRNA expression was analyzed by RT-PCR. The expression of collage type I and III was determined by immunohistochemistry.

RESULTSSerum LDH, CK and CK-MB reached their peaks at 4 h (chi2 = 16.90, P < 0.05), and AST achieved its peak in 6 h (chi2 = 16.90, P < 0.05). AT1R mRNA expression was increased 2 - 12 h after isoproterenol injection, but no statistical significance (P > 0.05) was observed comparing with the control. However, a significant AT1R mRNA increase was present at 24 h and decreased gradually after 48 h, and back to the control level after 3 weeks. Protein expression of AT1R increased proportionally with the severity of the fibrosis.

CONCLUSIONSAT1R mRNA and protein expressions increase significantly during myocardial ischemia, and is closely correlated with the fibrosis. These findings indicate that AT1R may play an important role in the pathogenesis of myocardial fibrosis.

AIMA series of triazole antifungal agents were synthesized to search for novel triazole antifungal agents with more potent activity, less toxicity and broader spectrum.

METHODSTwenty-one 1-(1H-1, 2, 4-triazolyl)-2-(2, 4-diflurophenyl)-3-(4-substituted-1-piperazinyl)-2-propanols were synthesized, on the basis of the three dimensional structure of P450 cytochrome 14alpha-sterol demethylase (CYP51) and their antifungal activities were also evaluated.

RESULTSResults of preliminary biological tests showed that most of title compounds exhibited activity against the eight common pathogenic fungi to some extent and the activities against deep fungi were higher than that against shallow fungi. In general, phenyl and pyridinyl analogues showed higher antifungal activity than that of the phenylacyl analogues.

CONCLUSIONSeveral title compounds showed higher antifungal activities than fluconazole and terbinafine. Compound VIII-1, 4, 5 and IX-3 showed the best antifungal activity with broad antifungal spectrum and were chosen for further study.
