Objective By using estradiol(E2) as positive control to observe the effects of genistein(GST) on the matrix metalloproteinase inhibitor 1 mRNA levels of HSC-T6 cell in vitro.Methods HSC-T6 cells were exposed to different concentrations of E2 0.1?mol/L and GST 0.5-50?mol/L for 36 hours.The TIMP-1 mRNA levels were measured by the quantitative reverse-transcription polymerase chain reaction(RT-PCR).Results The TIMP-1 mRNA levels of HSC-T6 cells at different concentrations of E2 and GST were lower than those of the normal control(P

Apolipoprotein C3 (APOC3) is a multifunctional protein.Its concentration is positively correlated with triglyceride (TG) levels and is an independent risk factor for coronary heart disease (CAD) prediction and development.Recent studies showed that APOC3 could not only regulate triglyceride-rich lipoproteins (TRL) metabolism,but also regulated endothelial function,that is,it could induce endothelial dysfunction and disorders of lipid metabolism.Gradually,APOC3 induces atherosclerosis (AS),increases the risk of the occurrence of CAD and other related diseases.APOC3 polymorphisms are also closely related to related diseases.

Objective To study clinical features, treatment and prognosis of nasal NK/T cell lymphoma associated Hemophagocytic Syndrome (HPS).Methods Retrospectively analysis method was used to analyze the clinical data of 3 patients with nasal NK/T cell lymphoma associated HPS. Results 3 patients with nasal NK/T cell lymphoma fulfilled the criteria of HPS. All patients had adverse prognostic factors of lymphoma.1 patient developed HPS as the main primary manifestations of underlying lymphoma,the other 2 patients developed HPS during lymphoma progression. In three cases, bone marrow was infiltrated with lymphoma cells.When HPS occurred,the disease progressed rapidly.The most obvious clinical features were fever,pancytopenia,hypofibrinogenemia,hyperferritinemia,and hemophagocytosis in bone marrow. After being treated according to the HLH-2004 combined with chemotherapy, all patients showed a clinical response,but with the progression of lymphoma,HPS quickly relapsed,and all patients died of severe hepatic dysfunction,coagulopathy,or DIC.Conclusion Nasal NK/T lymphoma associated HPS is an invariably fatal disease with poor prognosis,typically occurring at advanced stage or the terminal phase of the disease.HLH-2004 based protocol in combination with chemotherapy is helpful for nasal NK/T cell lymphoma associated HPS,which may delay disease progression and provid opportunities for the treatment of primary disease.

Bring up high quality medical talents with innovative consciousness and practical ability is the aim of high medical ed- ucation.Improving the innovative ability of teachers and quality of teaching with the perfect combination of science and humanities, so as to improve our understanding of the importance and necessity of innovation education,and carry out an overall quality edu- cation which chiefly works for the training of students' innovative consciousness and practical ability during practicing period.

Objective To compare the clinical outcomes of percutaneous cannulated lag screws versus posterior buttress plate in the fixation for posterior malleolar fractures.Methods We reviewed the 167 patients who had been treated between January 2010 and December 2014 for ankle fracture involving larger than 25％ of the articular surface of the posterior malleolus.They received posterior malleolus fixation with percutaneous cannulated lag screws or with a buttress plate.In the cannulated screw group (84 patients),there were 47 males and 37 females,aged from 23 to 72 years (average,49.7 ±9.1 years),and 39 cases of type B and 45 ones of type C according to the Dennis-Webber classification.In the buttress plate group (83 patients),there were 38 males and 45 females,aged from 31 to 69 years (average,52.3 ± 8.3 years),and 45 cases of type B and 38 ones of type C according to the Dennis-Webber classification.At 6 and 12 months postoperation and the final follow-up,the ankle motion was evaluated using American Orthopaedic Foot and Ankle Society (AOFAS) score and range of motion (ROM).Results The average operation time for the cannulated screw group was significantly shorter than for the buttress plate group (Z =-9.145,P ＜ 0.001).No fracture nonunion,reduction loss or incision infection happened in either group.In the cannulated screw group,we detected malunion with a step-off beyond 2 mm in 5 patients,and penetration of one cannulated lag screw into the tibiofibular syndesmosis in 3 patients.In the buttress plate group,we detected toe flexion contracture in 4 patients,and uncomfortable feeling in ankle motion in 7 patients.At the final follow-up,X-rays and CT scans in the 2 groups showed no obvious post-traumatic osteoarthritis of the ankle.There were no significant differences between the 2 groups regarding the AOFAS scores at 6 and 12 months postoperation and the final follow-up(P ＞ 0.05);the AOFAS scores at the final follow-up for all the patients were significantly different from those at 6 and 12 months postoperation (P ＜ 0.05).At the final follow-up,there were no significant differences between the 2 groups regarding ROMs of dorsal flexion,plantar flexion,varus or valgus (P ＞ 0.05).Conclusions As there are no significant differences between the percutaneous cannulated lag screws and posterior buttress plate in AOFAS score and ROM of the ankle after fixation for posterior malleolar fractures,the 2 fixation methods can both achieve good clinical outcomes.Fixation with cannulated lag screws has advantages of indirect reduction and minimal invasion but also a disadvantage of uncertain quality of reduction;fixation with buttress plates has an advantage of anatomical reduction under direct vision but also shortcomings of relatively large invasion and high cost.

ObjectiveTo detect the expression levels of macrophage migration inhibitory factor (MIF) in peripheral blood mononuclear cells (PBMCs),sera and skin tissue fluid from patients with vitiligo vulgaris,and to investigate their clinical significance.MethodsThirty-nine patients with vitiligo vulgaris and 31 age- and sex-matched normal human controls were recruited in this study.Real-time reverse transcription-PCR was employed to assess the expressions of MIF mRNA in PBMCs,enzyme-linked immunosorbent assay (ELISA) to detect the concentrations of MIF in sera and skin tissue fluid from these subjects.ResultsPatients with vitiligo vulgaris showed a significantly higher level of MIF mRNA in PBMCs (6.70 (2.64 - 8.65) vs.1.67 (1.24 - 2.45),Z=5.895,P＜ 0.05),MIF protein in sera (32.76 (10.67 - 40.98) μg/L vs.7.89 (6.13 - 9.54) μg/L,Z=5.936,P ＜ 0.05 ) and skin tissue fluid ( 167.80 ( 107.40 - 219.60) μg/L vs.42.44 (32.29 - 49.74) μg/L,Z =4.715,P ＜ 0.05) compared with the normal human controls.The expression levels of MIF mRNA in PBMCs,and MIF protein in sera and skin tissue fluid were also higher in patients with progressive vitiligo than in those with stable vitiligo (7.89 (3.89 - 9.12) vs.5.62 (2.23 - 7.29),Z=2.213,P＜ 0.05; 37.80 (29.50 - 45.70) μg/L vs.22.70 (9.36 - 37.78) μg/L,Z=2.141,P＜ 0.05; 211.50 (131.70 - 248.75) μg/L vs.144.65 (89.13 - 167.30) μg/L,Z =2.100,P ＜ 0.05).In addition,the vitiligo area severity index (VASI) score was positively correlated with the expression levels of MIF mRNA in PBMCs (r =0.486,P ＜ 0.05)and MIF protein in sera (r =0.453,P ＜ 0.05).ConclusionMIF might play a certain role in the pathogenesis of vitiligo vulgaris.
