Objective:To investigate the polymorphisms at HLA-A,-B,-DRB1 loci in Dalian Han population. Methods: A total of 10 000 unrelated marrow donors who live in Dalian were genotyped by SBT and SSO methods. Haplotype frequencies and linkage dis-equilibrium values were calculated by ARLEQUIN software,and DA genetic distances between populations were calculated by poptree2 software. Results: A total of 18 HLA-A alleles, 32 HLA-B alleles and 13 HLA-DRB1 alleles were found in Dalian Han population. HLA-A?02 (31. 65% ),B?40(14. 84% ) and DRB1?15(15. 82% ) occurred most frequently. A?30-B?13-DRB1?07 (4. 56% ) was determined to be the most common three-locus haplotype and the second predominant haplotype was A?02-B?46-DRB1?09 ( 2. 43% ) . A ?30-B ?13 ( 6. 00% ) and B ?13-DRB1 ?07 ( 59. 89% ) were the most common two-locus haplotypes. Moreover,A?33-B?58 and B?13-DRB1?07 were strongest haplotypes with the linkage disequilibria values 0. 336 6 and 0. 665 1,respectively. In China,the closest genetic distances were found with Heilongjiang (0. 001) followed by Jilin (0. 002) and Shandong (0. 002),the furthest was found with Taiwan (0. 047). Compared with other populations worldwide,the closest genetic distances were found with Thailand (0. 029) and Korea (0. 03),the furthest was found with Italy (0. 183). Conclusion: Dalian Han population had rich polymorphism at HLA-A,-B,-DRB1 loci,and the distribution of HLA-A,-B and-DRB1 was in line with the charac-teristics of the northern population.

Objective To investigate the efficacy of transvenous embolization in the management of cavernous dural arteriovenous fistulas.

Results Eight of the 9 patients were cured and 1 patient showed symptomatic improvement after the operations. No deterioration or death occurred in these cases. Follow-up of the patients for 2 to 96 months found no cases of relapse or exacerbation. Conclusion Transvenous embolization is effective and safe in the management of cerebral dural arteriovenous fistulas.

Introduction: Colorectal cancer (CRC) is a common type of neoplasm. This study examined the spatio-temporal distribution of the CRC incidence in Guangzhou during 2010–2014. Methods: Colorectal cancer incidence data were obtained from the Guangzhou Cancer Registry System. Spatial autocorrelation analysis and a retrospective spatio-temporal scan were used to assess the spatio-temporal cluster distribution of CRC cases. Results: A total of 14,618 CRC cases were registered in Guangzhou during 2010–2014, with a crude incidence of 35.56/100,000 and an age-standardized rate of incidence by the world standard population (ASRIW) of 23.58/100,000. The crude incidence increased by 19.70% from 2010 (32.88/100,000) to 2014 (39.36/100,000) with an average annual percentage change (AAPC) of 4.33%. The AAPC of ASRIW was not statistically significant. The spatial autocorrelation analysis revealed a CRC incidence hot spot in central urban areas in Guangzhou City, which included 25 streets in southwestern Baiyun District, northwestern Haizhu District, and the border region between Liwan and Yuexiu Dis-tricts. Three high- and five low-incidence clusters were identified according to spatio-temporal scan of CRC incidence clusters. The high-incidence clusters were located in central urban areas including the border regions between Bai-yun, Haizhu, Liwan, and Yuexiu Districts. Conclusions: This study revealed the spatio-temporal cluster pattern of the incidence of CRC in Guangzhou. This information can inform allocation of health resources for CRC screening.

Objective To analyze the therapeutic effects of microvaseular decompression on primary trigeminal neuralgia. Methods The general clinical data,culprit vessels and therapeutic effects of the surgical interventions were analyzed in 181 patients(aged from 24 to 79 years with a mean of54.9 years,including 78 male and 103 female patients)with established diagnosis of primary trigeminal neuralgia admitted from January,2000 to Deceber,2007. Results Blood type O was present in 43.65%of the 181 patients with trigeminal neuralgia,which had an increasing tendency compared to the national norm(33.8%).The morbidity ratio between the right and left side was 1.8:l in these patients.Forty-five patients(24.86%)were identified to have more than 2 culprit vessels.The culprit vessels included the superior cerebellar artery(96 cases),posterior inferior cerebellar artery(7 cases),anterior inferior cerebellar artery(25 cases),arteries communicated with veins(25 cases),internal auditory artery (13 cases),basilar artery(15 cases),vertical artery(9 cases),exclusive veins(15 cases,mainly vena pelrosa and bridging vein)and unknown vessels(9 cases).of the 181 cases,171(94.48%)were cured within one month,9(4.97%)showed relieved symptoms but required drug therapy,and 1 was in vegetative state(0.55%). Conclusions Patients with blood type O may have greater chance of developing primary trigeminal neuralgia.Microvascular decompression is an ideal treatment for primary trigeminal neuralgia,and clear identification of the culprit vessels can be crucial for decreasing the postoperative recurrence.

This study was designed to compare the curative effect, prognosis and safety of different preconditioning regimens for patients who received autologous hematopoietic stem cell transplantation (AHSCT) for malignant lymphoma (ML). The clinical data of 100 ML patients (Sep 1992 to Aug 2010 in 307 Hospital) were retrospectively analyzed, and were divided into two groups by different preconditioning regimens: the high-dose chemotherapy preconditioning group and high-dose chemotherapy/radiotherapy preconditioning group. The overall survival (OS) rate, progress free survival (PFS) rate and adverse effect were analyzed. The results showed that until Feb 2011, the median follow-up was 33.5 months. All patients were engrafted and their hematopoiesis was reconstituted. The median time of WBC recovery up to > 1.0×1.0(9)/L in high-dose chemotherapy preconditioning group and high-dose chemotherapy/radiotherapy preconditioning group were (6.0 ± 0.4) d and (8.2 ± 0.4) d, platelet up to > 20.0×1.0(9)/L in two groups were (7.1 ± 0.8) d and (11.4 ± 2.5) d (P < 0.05). The 3-year OS rate of the two groups were 67.3% and 68.9%. 5-year OS rates of two groups were 62.8% and 60.6%, 10-year OS rates of two groups were 57.6% and 56.2% respectively; 3-year PFS of two group were 63.6% and 63.2%, 5-year of two group were 59.4% and 58.3%, 10-year of two group were 50.8% and 55.3% respectively (P > 0.05). Meanwhile, the incidence of fever, infection, bleeding, secondary cancer between two groups was not significant different (P > 0.05). It is concluded that the hematopoietic reconstitution of high-dose chemotherapy/radiotherapy preconditioning group is later than that of high-dose chemotherapy preconditioning group. However, there is no significant difference in curative effect and prognosis between the two groups.

Objectives: To investigate the genetic mutation in a Chinese family with Pulmonary Arterial Hypertension (PAH). Methods: Whole exome sequencing was performed in two patients and two healthy family members in the PAH pedigree. Patient-specific variations were screened by bioinformatics methods and compared between groups. To further identify the association between these variations and PAH, Sanger sequencing was used to analyze the genotype of PAH patients and 100 healthy controls. Results: Two affected persons were found among the eight family members. The patients was presented as dyspnea after exercise, and right-heart catheterization was performed to measure the mean pulmonary arterial pressure (mPAP, 77 mmHg), cardiac output (CO, 4.92 L/min), and pulmonary vascular resistance (PVR, 13.4 Wood units). The hereditary characteristic in this family presented in mother and child, suggesting an autosomal dominant patter. Exome sequencing, mutation detection and sanger variants validation revealed a novel heterozygous frameshift mutation (c.747_748 insCCTTTGATGGAACATGA:p.V250fs) in the BMPR2 gene. Meanwhile, this heterozygous insertion mutation was absent in 100 ethnically matched control samples screened by direct sanger sequencing. Conclusions: Our study revealed a novel heterozygous frameshift mutation in the BMPR2 gene, expanding the BMPR2 mutation spectrums.

OBJECTIVE: To investigate the clinical manifestations and laboratory features of B-ALL patients with EP300-ZNF384 fusion gene positive, so as to improve the understanding of this subtype disease. METHODS: The clinical data of 3 B-ALL patients with EP300-ZNF384 fusion gene positive admitted in Department of Hematology, the first medical center of Chinese PLA general hospital from February 2017 to February 2018 were collected and analyzed retrospectively. The clinical and laboratory characteristics as well as the therapentic outcome in B-ALL patients with EP300-ZNF384 fusion gene positive were analyzed. RESULTS: The fusion gene of EP300-ZNF384 was detected in 8.1%(3/37) of B-ALL patients. All cases showed the normal karyotype and aberrant CD13 and/or CD33 expression for immunophenotype. 3 patients were sensitive to traditional chemotherapy. CONCLUSION The B-ALL with EEP300-ZNF384 fusion gene positive may be a subgroup of B-ALL with a uniqe clinical characteristis and laboatorial features. EP300-ZNF384 positive patients show a good response to conventional chemotherapy, suggesting a favorable prognosis.
