Objective To search for lymph node metastasis-associated proteins in human lung squamous carcinoma (hLSC).Methods Laser capture microdissection (LCM) was used to purify the target cells from lung primary tumor and matched lymph node metastatic tumor in hLSC. Two-dimensional gel electrophoresis (2-DE) was performed to separate the total proteins of microdissected tumor cells from lung primary tumor and matched lymph node metastatic tumor. PDQuest software was applied to analyze 2-DE images. Differential protein spots between the two types of tissues were identified by matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS). The expression of Rho-GDIα, one of the differential proteins, in the microdissected lung primary tumor cells (LPTC) and matched lymph node metastatic tumor cells (LNMTC) was detected by Western blot. Results In the present study, 2-DE patterns of microdissected LPTC and LNMTC were established, and 22 differential proteins in the above two tissues were identified, of which 14 were down-regulated in LNMTC and 8 were up-regulated in LNMTC.Conclusion The 22 differential proteins may play some roles in the process of lymph node metastasis in hLSC, and the data provide new clues for metastasis-associated biomarker screen and mechanism of hLSC.

OBJECTIVETo study the expression of NFkappaB p65 and its target genes in intestinal metaplasia (IM), dysplasia (Dys), gastric cancer (GC) infected with Helicobacter pylori (Hp) and explore the mechanism of infection by cytotoxin-associated antigen A expressing Hp (CagA(+)Hp) in the development of gastric cancer.

METHODSCagA antibody in blood sample of 289 patients was determined by ELISA. Hp was detected by rapid urease test and Warthin starry staining. Expression of NFkappaB p65 and its target genes in IM, Dys and GC was examined by immunohistochemistry.

RESULTSIn IMI approximately II, IMIII, DysI, DysII approximately III and GC, the expression of NFkappaB p65 was significantly higher in patients with CagA(+)Hp infection than those without CagA Hp infection. In IMIII and DysII approximately III, the expression of NFkappaB p65, c-myc, CyclinD(1) and bcl-xl was significantly higher in patients with CagA Hp infection than those without CagA Hp infection. In gastric cancer infected with CagA(+)Hp, the expression of NFkappaB p65, c-myc, CyclinD(1) and bcl-xl was significantly higher in intestinal type than in diffuse type.

CONCLUSIONThere are different mechanisms in intestinal type and diffuse type in the development of gastric cancer. The occurrence of intestinal type gastric cancer is associated with CagA(+)Hp infection which by NFkappaB p65 upregulating the expression of c-myc, CyclinD(1),bcl-xl in patients with IMIII, DysII approximately III. It may be an effective method to prevent gastric cancer by inhibiting NFkappaB p65.

OBJECTIVETo characterize the HA1 regions of hemagglutinin gene of influenza viruses (H3N2) isolated from children in Beijing from 1998 - 2004.

METHODSThe HA1 regions of hemagglutinin gene were amplified by RT-PCR from the viruses isolated and identified as A3 (H3N2) from clinical samples collected from infants and children during the peak seasons of influenza between 1998 and 2004. PCR products were sequenced or cloned into T-A vector and were analyzed after being sequenced.

RESULTSThe HA1 regions of hemagglutinin genes amplified from those isolates were 987 bp in length, encoding a protein of 329 amino acids in length. The identities of nucleotides and amino acids among these H3N2 isolates in Beijing and vaccines strains from 1998 - 2004 were 95.5% - 100.0% and 93.0% - 100.0%, respectively. The homology of the HA1 regions were related to the date of virus isolation, meaning the homology was higher among those strains isolated in nearer dates than others. Seven potential N-linked glycosylation sites in the HA1 regions located at amino acid positions 8, 22, 38, 63, 126, 165 and 285 were conserved in all the viruses analyzed. Two sites at 122 and 133 were inserted in those virus isolated after 1997, and another site at 144 appeared in those isolated after 1999. More amino acid substitutions located in the five putative antigenic sites or receptor binding sites were found more in the isolates than the isolates from previous year. Phylogenetic analysis showed new branches appeared continuously during 1998 - 2004. The strains isolated during winter in 2004 belonged to different branches, suggesting the appearance of new variants.

CONCLUSIONAmino acid substitutions continuously occurred in the HA1 regions of hemagglutinin genes in influenza virus (H3N2) isolated from children in Beijing from 1998 - 2004, which might have resulted in antigenic drift and led to the appearance of new variants.

OBJECTIVETo observe and compare the influence of acupoint sticking therapy in dog days and in non-dog days to the quality of life of allergic rhinitis patients.

METHODSFifty-five cases were divided into group A (the acupoint sticking therapy in dog days group, 28 cases) and group B (the acupoint sticking therapy in non-dog day group, 27 cases) randomly. The acupoint sticking therapy description (Dazhui (GV 14), Fengmen (BL 12), Feishu (BL 13) etc. was used in both groups. Five times of acupoint sticking therapy were given to patients in group A during dog days in 2010, while another 5 times of acupoint sticking therapy were given to patients in group B before the dog days. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was used to evaluate the effects before, after and half a year after treatment.

RESULTSThe scores of behavior problems, nasal symptoms and quality of life in RQLQ of both groups all decreased after treatment (all P < 0.01). The score of emotion reaction of group A in the follow-up period decreased compared with that before treatment (P < 0.05). The scores of non-nasal-or-ocular symptoms, ocular symptoms and emotion reaction after treatment and in the follow-up period all decreased than those before treatment (P < 0.01, P < 0.05). The decreasing degrees of scores of non-nasal-or-ocular symptoms, ocular symptoms, emotion reaction and quality of life after treatment and in the follow-up period in group A were all greater than those in group B (P < 0.01, P < 0.05).

CONCLUSIONIn the same season, both acupoint sticking therapy in dog days and in non-dog dags can improve the symptoms of allergic rhinitis, but the improving degree to quality of life in the method of acupoint sticking in dog days is greater.

OBJECTIVETo analyze the alterations of serum proteomic pattern in esophageal squamous cell carcinoma (ESCC) by SELDI-TOF-MS, to establish a diagnostic model of ESCC screening in high incidence area and investigate its clinical value.

METHODSSELDI-TOF-MS and CM10 proteinChip were used to detect the serum proteomic patterns of 36 cases of ESCC and 38 healthy control subjects in high incidence area. The data were analyzed and a diagnostic model was established by using support vector machine (SVM). The diagnostic model was evaluated by leave-one-out cross validation.

RESULTSAt the molecular weight range of 2000 to 20,000, 31 protein peaks were significantly different between ESCC and controls (P < 0.01). A diagnostic model consisting of 4 protein peaks could do the best in diagnosis of ESCC and controls. The accuracy was 85.1%, sensitivity was 86.1%, specificity was 84.2%, and positive value was 83.8%.

CONCLUSIONThe diagnostic model formed by 4 protein peaks, established in this study, can well distinguish ESCC from healthy subjects. It provides a new approach for ESCC screening in high incidence area.

OBJECTIVETo explore the characteristics of the whole genome of the influenza H1N1 virus of the mild and severe cases in Beijing.

METHODSA total of 21 samples of throat swabs were collected from surveillance-designated hospitals between June and December in 2009, including 10 severe cases (4 death cases) and 11 mild cases. RNA of the virus were extracted,and the amplified primers of the whole genome were designed.Reverse transcription and PCR were performed to the RNA and then the PCR product was sequenced by software to analyze the evolution of the viral genes and the variation of the amino acids.

RESULTSCompared with the reference vaccine strain A/California/07/2009 (H1N1), the genetic nucleotide homology in the eight segments of the pandemic H1N1 virus in Beijing in 2009 was higher than 99%, without significant variation. Among them,the genetic distance of hemagglutinin (HA), neuraminidase (NA) and nucleoprotein (NP) was comparatively far, separately 0.0050, 0.0040 and 0.0040.The gene of HA, P83S, the gene of NA, N248D, the gene of polymerase (PA), P224S and the gene of NP, V100I and L122Q were found to mutate in all the samples. Genes of HA, NA, NP, PA, PB 2 and nonstructural protein (NS1) in severe cases showed obviously clustered evolution. The mutation of gene S128P and S203T of HA, gene R269R and D547E of PA, gene T588I of PB 2 and gene I123V of NS mainly happened in severe cases, separately counting 6, 9, 6, 7, 9 and 6 cases. The relevance between the mutation happened in S203T of HA, R269K and D547E of PA and the severeness of the cases showed statistical significance (P < 0.05). The mutations of HA gene were mainly on the Ca and Cb antigene domains. No drug resistant mutation was found on NA gene but happened on matrix protein 2 (M2 gene). None of the mutations were found on the virulence related genes.

CONCLUSIONA high homology was found between the pandemic H1N1 virus in Beijing in 2009 and the reference vaccine strain A/California/07/2009(H1N1). Mutational sites related with the severe and fatal cases were found, but not the virulence related mutation.
