OBJECTIVE: To evaluate the clinical value of heterogeneous acellular dermalmatrix with autologous bone meal in open tympanoplasty. METHOD: Twenty-eight cases (30 ears) with middle ear cholesteatoma were trea- ted by open tympanoplasty and repaired by heterogeneous acellular dermalmatrix autologous bone meal on study team. Twenty-two cases (22 ears) with middle ear cholesteatoma were treated by open tympanoplasty on control team. All patients were followed up for 12 to 18 months and assessed the fuction postoperatively. RESULT: The re- construction of external auditory canal structure is close to normal, and no narrow happens on study team. The rate of dry ear was about 90%. All cases had no recurrence of cholesteatoma. CONCLUSION Application of decellu- larized dermal matrix with autologous bone meal can rise early to cover the wound, promote wound healing and to reduce the external auditory canal, reduce the effect of granulation and scar formation. It is a kind of method of repair to be promoted.

Objective To investigate the expression of DcR3 mRNA in cells of acute leukemia(AL) and its clinical significance.Methods The DcR3 mRNA of bone marrow mononuclear cells(BMNC) in the patients with AL was detected by RTPCR.There were 28 AML cases,and 18 ALL cases.27 cases of non-malignant hematopathy were used as control group.The expression level of DcR3 mRNA in BMNC was detected with RT-PCR.Results The positive rate of DcR3 mRNA was 67.4% and gene expression level was 0.56?0.09 in AL group,while they were 40.7% and 0.39?0.19 in control group,there were significant differences(P0.05).The positive expression level of DcR3 mRNA increased when the white blood cell count was ≥30?109?L-1.Conclusion DcR3 gene might play a role by suppressing apoptosis in leukemogenesis.

Objective To study the vestibular function in patients with sudden deafness .Methods Retrospec-tive analysis of 436 cases of patients with sudden deafness ,being divided into two groups according to whether the merger of vertigo .147 cases with vertigo group ,75 cases of which were mild to moderately severe hearing loss .In-clud the rise type of 28 cases ,26 cases of flat type ,21cases of decline type .72 cases of which were severe hearing loss .In 289 cases without vertigo ,157 cases had mild moderate and severe hearing loss .Includ the rise type of 36 cases ,57 cases of flat type ,64 cases of decline type .One hundred and thirty two cases of which were severe hearing loss .Use video electronystagmogram (VNG) to test the vestibular function .Process the data with SPSS 13 .0 soft-ware .Results One hundred and twenty three(83 .7% )cases of the vertigo group suffered from vestibular function decline ,with 51 cases of mild to moderately severe hearing loss ,72 cases of severe and above .165 (57 .1% )cases of the without vertigo group suffered from vestibular function decline .There were 45 cases of mild to moderately se-vere hearing loss ,120 cases of severe and above .35 patients with vertigo patients with BPPV ,28 cases of which happened within 1 week in sudden deafness occured and 80% of which were vestibular function decline .Conclusion Patients with sudden deafness with vertigo suffered from vestibular function damage .Patients with sudden deafness without vertigo also suffered from vestibular function damage .And the more serious the hearing loss ,the higher the vestibular function decline opportunities .

Objective:To analyze the laboratory parameters and clinical characteristics of TTP patients, so as to provide reference for the timely diagnosis and death risk assessment or TTP.Methods:83 patients with TTP from June 2016 to March 2022 in our hospital were analyzed retrospectively. They were divided into survival and death groups. The differences in general information, clinical symptoms and laboratory parameters were compared between the two groups. The prognostic prediction score was constructed by combining parameters which differ between the two groups to calculate the corresponding mortality risk.Results:83 patients were included in the study, of whom 81.1% (60/74), 91.1% (72/79) and 86.2% (50/58) had increased AST, IBIL and cTnI results, and all (78/78) had higher LDH at admission. Hb was decreased in 97.5% (79/81) patients, and PLT of 97.5% (79/81) patients was less than 30×10 9/L. There were no significant differences in gender, age, blood type, presence of fever, ADAMTS-13 activity and PLASMIC score between the survival group (58 cases) and the death group (25 cases), but the proportion of neurologic symptoms in the death group was significantly higher than that in the survival group. AST, IBIL, cTnI and APTT at admission were significantly higher in the death group than in the survival group ( P<0.05). The risk of death was 4.86, 9.74, 3.71, and 5.33 for those with high AST, IBIL, APTT, and cTnI levels, respectively, compared with those with low levels at admission. At last, AST, IBIL, APTT, cTnI and neurological symptoms were included to construct a score model. For each 1 point increase, the risk of short-term death in TTP patients was 3.24. Conclusions:Multiple laboratory markers have high negative exclusion value for TTP. For TTP patients with high AST, IBIL, cTnI and APTT and neurologic symptoms, more attention and active treatment should be paid to reduce mortality.

OBJECTIVETo understand the association between multiple genetic loci identified by genome-wide association studies (GWASs) and colorectal cancer (CRC) risk, and whether these genetic factors, along with traditional risk factors, could contribute to the colorectal cancer risk prediction in a Chinese Han population.

METHODSA case-control study (1 066 CRC cases and 3 880 controls) was initially conducted to assess the association between 21 recently discovered single-nucleotide polymorphisms (SNPs) and CRC risk. Genetic risk score (GRS) and weighted genetic risk score (wGRS) were calculated to evaluate the joint effects of selected loci. Multiple models combining genetic and non-genetic factors were established and receiver operating characteristic curve analysis was used to compare the discriminatory power of different predictive models.

RESULTSThere were 7 SNPs significantly associated with CRC susceptibility. As the GRS or wGRS increased, the risk of CRC also increased (trend P=0.002 6 for GRS, trend P<0.000 1 for wGRS). The ORs for highest versus lowest quartile of GRS and wGRS were 1.33 (95% CI: 1.12-1.58, P=0.001 0) and 1.76 (95% CI: 1.45-2.14, P<0.000 1) , respectively. The model incorporating wGRS and traditional risk factors, including sex, age, smoking and drinking, was the best one to predict CRC risk in this population, with an area under curve of 0.593 (95% CI: 0.573-0.613).

CONCLUSIONMultiple genetic loci identified by GWASs jointly influenced the CRC risk. The combination of genetic factors and conventional non-genetic factors improved the performance of risk predictive model for colorectal cancer.
