OBJECTIVETo evaluate the value of normalization window of tumor vasculature (NWTV) in patients with unresectable gastric cancer undergoing neoadjuvant chemotherapy.

METHODSFrom October 2010 to March 2011, 93 patients with unresectable advanced or locally advanced gastric carcinoma were prospectively collected and randomly divided to Group A(n=30), Group B(n=29), and Group C(n=34). Group A received FOLFOX4 as conventional neoadjuvant chemotherapy. Group B received FOLFOX4 plus bevacizumab. The treatment was adjusted in Group C according to the hypothesis of NWTV with neoadjuvant chemotherapy delivered 5 days after bevacizumab treatment. The efficacy, drug toxicity and clinical outcome were assessed and compared between the three groups.

RESULTSThere were no significant differences among the 3 groups in demographics(P>0.05). All the patients completed the neoadjuvant chemotherapy. Efficacy and toxicity between the three groups were comparable(P>0.05). The rates of tumor downstaging in the three groups were 56.7%(17/30), 72.4%(21/29), 85.3%(29/34), respectively, with a significantly lower downstaging rate in Group C as compared to Group A(P<0.05). R0 resection rates were 23.3%(7/30), 27.6%(8/29), 52.9% (18/34), respectively, with significantly higher R0 resection rate in Group C as compared to Group A and Group B(All P<0.05). There was no perioperative death in this cohort. Postoperative complications were comparable among the 3 groups(P>0.05).

CONCLUSIONSAnti-angiogenesis agent can improve the efficacy of neoadjuvant chemotherapy in unresectable gastric cancer. Furthermore, administration according to NWTV may achieve better outcomes.

OBJECTIVETo explore therapeutic effects of bone setting manipulation for the treatment of over degree II supination-eversion fractures of ankle,and analyze manipulative reduction mechanism.

METHODSFrom 2005 to 2008, 95 patients with over degree II supination-eversion fractures of ankle were treated respectively by manipulation and operation. There were 43 cases [11 males and 32 females with an average age of (44.95 +/- 12.65) years] in manipulation group, and 2 cases were degree II, 11 cases were degree III, and 30 cases were degree IV. There were 52 cases [21 males and 31 females with an average age of (39.96 +/- 13.28) years] in operative group,and 6 cases were degree II, 18 cases were degree III, and 28 cases were degree IV. Bone setting manipulation and hard splint external fixation were applied to manipulative group. Operative reduction internal fixation was performed in operative group. X-ray was used to evaluate reduction of fracture before and after treatment, 2 months after treatment. Ankle joint function was evaluated according to Olerud-Molander scoring system after 6 months treatment.

RESULTSAll patients were followed up with good reduction. Three cases occurred wound complication in operative group, but not in manipulative group. In manipulation group, 19 cases got excellent results, 20 cases good and 4 cases fair; while in operative group, 30 cases got excellent results, 20 cases good and 2 cases poor. There were no significant differences in fracture reduction and ankle joint function recovery between two groups (P > 0.05). Efficacy of operative treatment was better than that of manipulative treatment at degree IV fracture (P < 0.05).

CONCLUSIONBone setting manipulation is a good method for treating supination-eversion ankle joint fractures, which has advantages of simple and safe operation, reliable efficacy. For ankle join fracture at degree IV, manipulative reduction should be adopted earlier, and operative treatment also necessary

OBJECTIVETo study the correlation between cyclin E protein overexpression and centrosome amplification in oral squamous cell carcinoma (OSCC).

METHODSFormalin-fixed, paraffin-embedded tissues from 12 normal oral epithelium cases and 46 cases of OSCC were studied. Their centrosome status was analyzed by indirect immunofluorescence double staining with antibodies to centrosome protein gamma-tubulin and cytokeratin. The expression of cyclin E protein was studied by immunohistochemical methods. The correlation between cyclin E protein expression and centrosome amplification in OSCC was statistically analyzed by SPSS 12.0.

RESULTSThirty-seven of the 46 OSCC cases (80.4%) studied showed evidence of centrosome amplification, as signified by enlargement and/or increase in number of centrosomes, while normal oral epithelium possessed centromeres of normal size and number. Positive staining for cyclin E protein was observed in 30 of the 46 OSCC cases (65.2%), while all the normal oral epithelium cases were cyclin E protein-negative. The percentage of centrosome amplification in OSCC with positive cyclin E protein staining (90.0%, 27/30) was higher than that in OSCC with negative cyclin E protein staining (62.5%, 10/16) (chi(2) = 5.014, P < 0.05). Centrosome amplification showed positive correlation with cyclin E protein overexpression (r = 0.330, P < 0.05).

CONCLUSIONUp-regulation of cyclin E protein may represent one of the possible mechanisms for centrosome amplification in OSCC.

OBJECTIVETo evaluate the expression of HDGF and its implication in patients who undergone radical resection for stage I non-small cell lung cancer.

METHODSImmunohistochemical technique was applied to detect the expression of HDGF in 118 lung cancer tissues and 30 normal lung tissues as control. At the same time, the expression of VEGF and Ki-67 labeling rate of the tumors was evaluated.

RESULTSHDGF expression was observed in all cases, and significantly higher than that in normal lung tissues (52.23 +/- 10.35 vs. 156.73 +/- 70.95, P < 0.01). Expresson of HDGF was closely related to histological classification, and the expression in adenocarcinoma was much stronger than that in squamous cell cancers (P = 0.001), but not related to other clinicopathological factors. VEGF expression was closely related to the expression of HDGF. HDGF expression in the VEGF high expression group was much higher than that in VEGF low expression group (171.77 +/- 81.07 vs. 142.81 +/- 59.84, P = 0.028). Ki-67 expression was also closely related to the expression of HDGF, the labeling rate of Ki-67 in high HDGF expression group was much higher than that in low HDGF expression group (30.49% +/- 7.88% vs. 17.80% +/- 5.63%, P = 0.001). Univariate analysis showed that the patients with high HDGF expression had a shorter overall survival than that with low HDGF expression (40.0% vs. 77.5%, P = 0.008), and multivariate Cox regression analysis showed that HDGF was a significantly independent predictive factors for patients with stage I NSCLC (RR = 1.011, P = 0.002).

CONCLUSIONHDGF expression is upgraded in postoperative stage I non-small cell lung cancer patients. HDGF is a significantly independent predictive factor for patients with stage I NSCLC. HDGF may play an important role on carcinogenesis and development of stage I NSCLC through promoting cell proliferation and neoangiogenesis of the tumor.

OBJECTIVETo explore the role of monitoring sex chromosome chimeric status by fluorescence in situ hybridization (FISH) in the identification of leukemic extramedullary relapse and post-transplant lymphoproliferative disease (PTLD) in acute lymphocytic leukemia (ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSSix ALL patients who received sex-mismatched allo-HSCT and manifested extravisceral lymphadenectasis or local lump were investigated. The sex chromosome chimeric status in tumor tissues and bone marrows (BM) were monitored by FISH, and EBV-RNA in the tumor tissues were detected by in situ hybridization (ISH).

RESULTSThe sex chromosomes in BM of all 6 patients were 100% donor-derived. Among the sex chromosome chimeric status of tumor tissues, three patients were mainly recipient-derived, and the percentage of sex chromosomes derived from recipients were 100%, 100% and 98.0%, respectively, and then they were diagnosed leukemic extramedullary relapse. The other 3 patients were donor-derived, the percentage was 98.5%, 96.0% and 91.5%, respectively, and were diagnosed PTLD. EBV-RNA and latent membrane protein (LMP-1) were positive in 2 patients with PTLD and negative in the other 4 patients. One patient with extramedullary relapse obtained partial remission, one with PTLD gained complete remission, and the others died eventually after therapy.

CONCLUSIONMonitoring the sex chromosome chimeric status by FISH is an effective method to distinguish leukemic extramedullary relapse from PTLD in ALL received sex-mismatched donor HSCT.
