Objective: To establish the database on typing of Chin es e condyle head by skull base position X ray analysis. Methods: 51 Chinese volunteers (male 33, 65 condyles; female 18, 35 condyles) accep ted skull base position X ray inspection. Then the 100 condyle images were ana lyzed and the contribution of the types among sexes and sides were also analyz ed. Results: The types of condyle were divided into A,B,C, D,E(E1,E2) and F(F1,F2).Among all condyle types, type A was accounted for 41.0% , while type F1 only 1%. The contribution of the types between left and right si des was almost the same. 51% (26 pairs) of the two condyles in the same person share the same type, the other 23 pairs of condyles were in different types (mal e 39.1 %, female 60.9%). Conclusion: The morphology typ ing of condyle heads by skull base position X ray analysis may be reference to clinical application.

objective: To evaluate the embolization effect of 5 Fu gelatin microsphere(FGM) in oral and maxillofacial region.Methods: FGM was prepared with drug load of 12% and encapsulation of 85%. After irridiated with 60 Co, FGM was suspended into 76% of meglumine diatrizoate, and then perfused into external maxillary artery and lingual artery in 8 dogs under X ray observation. 4 dogs were used in each artery embolization. Blood flow velocity and volume in the arteries were tested at different time after embolization; all the data were analyzed statistically. The sections of embolized tissue at different time were examined microscopically. Results: Before and 1 h, 48 h and l month after ombolization the blood flow volume(ml/min) in external caroted artery was 43?5.0, 31.0?4.5, 26.5?4.0 and 35.0?30; that in external maxillary artery 5.0?1.5, 0.5?1.0, 2.5?1.0 and 3.0?1.5; in ligual artery 3.5?1.0, 0.5?0.5, 0 and 0; in internal maxillary artery 17.0?4.0, 19.5?4.0, 19.0?4.5 and 21.0?3.5, respectively. Stuff of the cavity of the corresponding arteries by FGM were found with histological examination. Conclusion: FGM can embolize artery completely.

Objective: To analyse the acuracy of color doppler ultrasound examination in the measure- ments of blood vessels in tissue flaps. Methods: 110 pieces of associated blood vessel in tissue flaps in 64 cases were measured with color doppler ultrasound examination before operation. The quality of blood vessel, its diameter, blood stream filling, the vascular pedicle length and its depth were measured. The results were checked and compared with the findings in operation. Results: Of all 110 pieces of associated blood vessel evaluated by doppler, the accurate ratio confirmed by the finding in operation was 100%. The inner diameter of 38 pieces of blood vessel measured in operation was coincident with that measured by doppler before operation, or with little difference. Conclusion: The color doppler ultrasound examination is a reliable method for evaluating the blood vessel both of the donor and host areas in maxillofacial reconstruction surgery with tissue flap.

Objective:To evaluate 2D ultrasonography(2DUS), color Doppler flowing imaging(CDFI) and color Doppler energy (CDE) in the differential diagnosis of benign and malignant tumors of salivary glands.Methods:According to the characters of 2DUS and CDFI examination, benign and malignant tumors in 142 cases of salivary glands were distinguished. The results of ultrasound examination and postoperative biopsy were checked and compared. Meanwhile the same tumor's blood flow information and hemodynamics index were compared. Results:In 2DUS examination, the inter echo and post echo of benign and malignant were different. In CDFI examination, the blood flow form could be displayed clearly. Besides Warthin tumors, the blood supply ranking of benign tumors was usually levelⅠor Ⅱ-(78.7%), and that of malignant tumors was levelⅡ+ or Ⅲ(80.0%). The artery's peak systolic velocity(PSV) of malignant tumors was higher than that of benign tumors. The rates(%) of sensitivity, specificity,accuracy,false negative, false positive, positive predicting and negative predicting of 2DUS were 70.2,87.4,81.7,29.8,12.6,73.3 and 85.6,those of CDFI 80.9,65.2,70.4,19.1,34.7,53.0 and 87.3,those of the integrated usage of ultrasonic methods 89.3,90.5,90.1,10.6,9.5,82.4 and 94.5 respectively.Conclusion:With the integrated usage of ultrasonic methods, higher accuracy of differential diagnosis for benign and malignant salivary glands tumors may be obtained.

Objective To investigate the expression of tumor metastasis associated protein I (MTA1) in esophageal cancer tissue and its relationship with clinicopathological features and 3-year survival rate.Methods Ninety-six postoperative pathological samples of esophageal cancer and 40 samples of paracancerous tissue conforming to the inclusion standard collected by the pathological department of this hospital from January 2010 to December 2012 were selected and performed the immunohistochemical staining.Then the relationship between MTA1 protein expression with the clinicopathological features and long term survival rate was analyzed.Results The MTA1 protein expression rate in the esophageal cancer tissueswas 73.96％,which was significantly higher than 2.50％ in paracancerous tissues (P＜0.05);esophageal cancer tissues MTA1 protein expression mainly had significant correlation with TNM stage and lymph node metastasis(P＜0.05);the 3-year survival rate in the patients with esophageal cancer tissue MTA1 protein positive expression was 33.80 ％,which was significantly lower than 60.00 ％ in the patients with MTA1 protein negative expression (P＜0.05);the long-term survival rate in the patients with esophageal cancer had significant relationship with TNM staging and MTA1 protein expression (OR=1.638,OR=1.433,P＜0.05).Conclusion MTA1 protein is highly expressed in esophageal cancer tissue,and has the relationship with TNM stage and lymph node metastasis,MTA1 protein high expression is an independent risk factor for the prognosis in the patients with esophageal cancer.

To investigate the presence of integrated Epstein-Barr virus (EBV) DNA in the NK/T cell lymphoma (NKTCL) ge-nome and analyze the integration information in the genome of NKTCL cell lines. Methods: PCR and in situ hybridization were used to detect EBV infection in five EBV (+) NK/T samples and four EBV (-) NK/T samples provided by the biobanks of the First Affiliated Hospi-tal of Zhengzhou University. Whole-genome DNA of the samples was sequenced and subjected to bioinformatics analysis. Whole-ge-nome sequence alignment was used to identify the EBV integration sequence. BLAST analysis was used to compare EBV fasta files of the samples and EBV fasta library. CREST software was used to extract softclip reads, filter all paired reads, and enumerate their distri-bution on chromosomes. The integrated genomics viewer (IGV) was used to compare the distribution of reads in partial regions of chromosome. PCR was used to amplify the high-frequency integration region of the EBV DNA. The amplified fragments were sanger se-quenced. Results: EBV DNA and EBER expression were detected in five EBV (+) NK/T samples but not in the four EBV (-) NK/T samples. Sequencing depth, coverage depth, proportion of coverage, and proportion of alignment all met the requirements for subsequent re-search. Sequence alignment revealed that the captured sequences were viral sequences. Filtered reads were most numerous in EBV (+) NKTCL cell line SNK, YTS, and EBV (+) nasal NKTCL tissue. The reads were non-randomly enriched in chromosome 2. EBV DNA inte-gration in the 400 bp region of chr2:30234084-30234483 caused insertion or deletion in the chr2p23.1 site. Conclusions: EBV DNA is highly integrated in the chr2p23.1 site of EBV (+) NKTCL cells and may affect the expression of related genes.

Objective: To investigate the expression and clinical significance of programmed death-ligand 1 (PD-L1), programmed death-ligand 2 (PD-L2), and their receptor programmed cell death protein 1 (PD-1) in EBV-positive T/NK lymphoproliferative disease [Epstein-Barr virus-positive T/natural killer (NK)-cell lymphoproliferative disease, EBV(+)-T/NK-LPD]. Methods: The pathological paraffin-embedded tissues of 17 patients with EBV(+)-T/NK-LPD from the First Affiliated Hospital of Zhengzhou University from January 2013 to December 2017 were collected. These patients include 12 males and 5 females, aged 10-82 years old, the average age being 29 years, 4 people in gradeⅠ, 7 in gradeⅡ, 3 in gradeⅢ, and 3 people with hydroa vacciniforme-like lymphoproliferative disorders. Immunohistochemical SP method was used to detect the expression of PD-1, PD-L1, and PD-L2 in human EBV(+)-T/NK-LPD tissues. The relationship between PD-1, PD-L1, PD-L2 expression, and clinicopathological parameters, pathological grades and prognosis were analyzed by Fisher's exact probabilities and Spearman rank correlation. Result: After statistical analysis, the results showed that in 17 cases of tissue samples, there were 12 cases with positive PD-1 expression, 6 cases with positive PD-L1 expression and 5 cases with positive PD-L2 expression. There was no significant correlation between PD-1 and PD-L2 expression and prognosis (P>0.05). PD-L1 expression showed a positive correlation with prognosis (P<0.05). There was no significant correlation between the expression of PD-L1 and PD-L2 with age, sex, as well as LDH and Ki-67 levels (P>0.05). Moreover, there was no significant correlation of PD-1 and PD-L2 expression with pathological grade (r=0.141, r=-0.149, both P>0.05). However, there was a negative correlation between the PD-L1 expression and pathological grade (r=-0.563), and the correlation between the PD-L1 ex-pression and pathological grade was statistically significant (P<0.05). Conclusions: PD-1, PD-L1, and PD-L2 are abnormally expressed in the pathological tissues of EBV(+)-T/NK-LPD. Although there was no significant correlation between the expression of PD-1 and prognosis or pathological grade, it was significantly higher in EBV+T/NK-LPD. PD-1/PD-Ls associated signaling pathway is expected to be a potential new target for EBV(+)-T/NK-LPD immunotherapy.
