To study the clinical effect of arthroscopic anterior cruciate ligament (ACL) construction with different transplants. From March 2006 to April 2009, 86 patients including 60 male and 26 female undergoing arthroscopic ACL reconstruction were prospectively randomized consecutively into autograft group (44 patients, using autogeneic hamstring tendons) and allograft group (42 patients, using allogenic lower extremity tendons). The age of those patients were 22 - 56 years, averaging (32 ± 7) years. The operations were made by the same doctor with the standard technology. The postoperative effects were assessed by the range of motion and tibia forward distance, Lachman test, pivot shift test, Daniel test, IKDC scores systems, Lysholm-Tegner scores. Seventy-nine patients were followed up, 41 patients in autograft groups averaged 39.6 months and 38 patients in allograft group averaged 37.4 months. The operation time of autograft group was (87 ± 11) minutes, that of allograft group was (55 ± 10) minutes (t = 15.732, P < 0.05). The time of postoperative fever of autograft group was (3.2 ± 1.4) days, that of allograft groups was (7.6 ± 5.3) days (t = 5.740, P < 0.05). The Lysholm scores of autograft group was 42 ± 7 before operation, and 89 ± 8 at final follow-up. The Lysholm scores of allograft group was 44 ± 6 before operation, and 87 ± 9 at final follow-up. There was statistic difference in both groups between before operation and final follow-up (t = 13.534 and 17.768, P < 0.05).But no statistic difference existed between the two groups (P > 0.05). The Tegner scores of autograft group was 2.9 ± 2.1 before operation, and 7.7 ± 1.2 at final follow-up. The Tegner scores of allograft group was 2.7 ± 1.4 before operation, and 7.1 ± 1.6 at final follow-up. There was statistic difference in both groups between before operation and final follow-up (t = 16.004 and 12.338, P < 0.05).No statistic difference existed between the two groups (P > 0.05). The KT2000 results showed that the anterior displacement of autograft groups was (10.7 ± 3.5) mm before operation and (5.0 ± 2.7) mm at final follow-up, the anterior displacement of allograft groups was (10.9 ± 2.9) mm before operation and (6.5 ± 2.4) mm at final follow-up, there was statistic difference between before and after operation in anterior displacement in two groups (t = 16.354 and 13.296 P < 0.05). There was no difference between two groups before operation and at final follow-up. Compared to before operation, the IKDC scores were improved greatly after operation (P < 0.05). The clinical effect of arthroscopic ACL construction with allograft transplants is near to autograft.

To investigate the correlation between Chinese medical syndrome type (CMST) and the ID4 gene promoter methylation state in the bone marrow cells of acute myeloid leukemia (AML) patients, and to discuss the correlation between ID4 gene methylation and the occurrence, development of AML. Thirty-five inpatients or outpatients from the Department of Hematology, the Affiliated Hospital of Shandong University of Traditional Chinese Medicine were recruited as the test group, while 10 healthy volunteers from the health medical center of the Affiliated Hospital, Shandong University of Traditional Chinese Medicine were recruited as the control group. The ID4 gene promoter methylation states were detected using methylation specific polymerase chain reaction (MS-PCR) in the two groups. Inter-group comparison was performed and CMSTs were compared to analyze the correlation between CMSTs and the gene promoter methylation. Twenty-seven AML patients (77.1%) had methylation of ID4 gene, showing statistical difference when compared with the control group (P < 0.01). The ID4 methylation positive rate of ID4 gene promoter methylation was sequenced from low to high as qi and yin deficiency syndrome < inter-accumulation of blood stasis and phlegm syndrome < toxic heat inflaming syndrome, showing statistical difference when compared with the control group (P < 0.05). The peripheral white blood cells and the bone marrow blast cells were higher in ID4 methylation positive patients than in the ID4 methylation negative control patients with statistical difference (P < 0.05). Patients of inter-accumulation of blood stasis and phlegm syndrome and toxic heat inflaming syndrome were more likely to have ID4 gene methylation. The ID4 methylation positive expression has verified the essence of evil domination in the early AML at the molecular level. It can also reflect the degree of malignancy of AML to some extent.

Objective: The relationship between APE1 and XRCC1 gene polymorphism and the susceptibility to hepatocellular carcinoma (HCC) was discussed, and the effect of APE1 and XRCC1 gene polymorphism on the sensitivity of HCC to cisplatin was investigated. Method: From January 2010 to August 2014, 118 HCC patients were admitted to our hospital. 120 patients treated for non-tumor diseases during this period were recruited as controls. PCR-RFLP analyses were performed to determine the association between APE1 Asp148Glu and XRCC1 Arg194Trp polymorphism, risk of HCC, and sensitivity to cisplatin. Results: The risk of HCC in patients with Glu/Glu genotype of APE1 gene was increased by 4.510 times (95% CI: 1.235~16.472, P<0.05). Compared with Asp/Asp, the risk of cisplatin resistance in patients with Glu/Glu genotype was increased by 10.500 times (95% CI: 1.800~61.241). Compared Arg/Arg genotype, the risk of cisplatin resistance in patients with Arp/Trp genotype of XRCC1 gene was increased by 6.701 times (95% CI: 1.464~30.732, P<0.05). Conclusion: APE1 Asp148Glu polymorphism is associated with the susceptibility to HCC. APE1 Asp148Glu and XRCC1 Arg194Trp polymorphism plays a part in the cisplatin resistance of HCC cells. © 2015, E-Century Publishing Corporation. All rights reserved.

Background/Aims: SUZ12 and EZH2 are two main components of polycomb repressive complex 2 (PRC2) that is known to be of great importance in tumorigenesis. EZH2 has been reported to play a vital role in pathogenesis of human cancer. However, whether SUZ12 has equivalent roles in tumorigenesis has not been demonstrated. Here, we investigated a possible role of SUZ12 for the proliferation of gastric cancer cells. Methods: Western-blot analysis was used to detected the levels of SUZ12, H3K27me3, EZH2 and p27 in ten gastric cell lines. SUZ12 was depleted by RNA interference. Cell cycle was detected by flow cytometry. Luciferase assays was to analyze whether miR-200b directly regulate SUZ12. Results: We found that SUZ12 depletion mediated by RNA interference (RNAi) led to a reduction of gastric cell numbers and arrested the cell cycle at G1/S point. As an important G1/S phase inhibitory gene, p27 is re-induced to some extent by SUZ12 knockdown. Furthermore, we demonstrated that SUZ12 was directly downregulated by miR-200b. Conclusion: We provide evidence suggesting that SUZ12 may be a potential therapeutic target for gastric cancer. Copyright © 2013 S. Karger AG, Basel.

Objective: To observe the effect of small-dose mifepristone conservative treatment and laparoscopic combined with mifepristone in the treatment of endometriosis. Materials and Methods: Sixty-five endometriosis cases were given small-dose mifepristone conservative treatment and were assessed for the effect of this treatment; 92 cases were randomly divided into control group (taking gestrinone) and observation group (mifepristone), FSH, P, PRL and E2 levels were compared before and after treatment, and pregnancy investigation and each sex hormone level monitoring were followed-up at one year after drug withdrawal. Results: Using mifepristone, FSH, P, E2, and LH levels all significantly changed six months after treatment and recovered 12 months after drug withdrawal; when comparing the pelvic symptoms, endometrial thickness showed that mifepristone was significantly effective (p < 0.01), and the pregnancy rate was 27.69%. Comparing the two groups, none of the total effective rate, pregnancy rate one year of follow-up, and recurrence rates were significantly different; hormone levels in the both groups were significantly decreased or increased (p < 0.05) after treatment. The two groups had no significant difference (p > 0.05), but 12 months after drug withdrawal, in the control group (not in the observation group), LH level was still significantly different (p < 0.05) compared pre-treatment. Conclusions: In the conservative treatment, mifepristone can safely improve the hormone levels, reduce the thickness of the endometrium, alleviate symptoms. With laparoscopic minimally invasive combined drug therapy, mifepristone has a significant effect, with a more followed-up pregnancy rate, less recurrence, and no drug accumulation side-effects, hence it is worthy of clinical application.
