Objective To evaluate clinical efficacy of treating femoral intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures using anatomic locking plate.Methods From January 2009 to June 2011,we treated 72 cases of femoral intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures using anatomic locking plate.Sixty-four cases were followed up.There were 50 males and 14 female,with an average age of 42.8 years (range,21-79).All patients suffered from closed femoral unilateral fractures.The interval between injury and surgery was 2 h-16 d (average,4.6 d).All patients were followed up at regular interval.During the follow-up period,clinical and radiographic data were recorded.The clinical efficacy was evaluated with Harris hip function score.Results The mean operative time was 65 min (range,45-120 min); the mean blood loss was 210 ml (range,50-650 ml).All patients began to walk with crutches 3-35 d after surgery.During the follow-up period,no infection,deep vein thrombosis,screwed cut-out and implant failure occurred in all patients.Coxa vara with shortening deformity was noted in 2 cases,solid bone union was found in all the cases.The mean time of fracture healing was 5.2 months (range,3.6-10.5 months).According to Harris hip score,45 cases were classified as excellent,14 as good and 5 as fair,with excellent and good rate being 92.19％ (59/64).Conclusion Anatomic locking plate fixation provides stable fixation,with a high union rate and a minimal complication rate in treatment of intertrochanteric and subtrochanteric fractures combined with femoral shaft fracture.

OBJECTIVE: To investigate the down-regulation effect of let-7b-5p on the expression of FTO in acute myeloid leukemia cell line THP-1 and inhibitory effect on THP-1 proliferation via m METHODS: The acute myeloid leukemia cell line THP-1 and the normal human peripheral blood mononuclear cells (PBMNC) were selected as subjects. The expression of let-7b-5p and FTO mRNA in those cells was detected by qPCR, further the expression of FTO protein in those cells was detected by Western blot. And, the luciferase reporter gene assay was used to verify the targeting effect of let-7b-5p on FTO. Finally, THP-1 cells were transfected respectively with let-7b-5p mimic, and PBMNC with let-7b-5p inhibitor, there after the C-MYC mRNA m RESULTS: Compared with PBMNC, the expression of let-7b-5p in THP-1 significantly decreased, while the expression of FTO was significantly increased (P<0.05). After transfection with let-7b-5p mimic combined with FTO 3'-UTR, the luciferase activity of transfected THP-1 cells significantly decreased, but the luciferase activity significantly increased after transfection with mutant 3'-UTR, which was significantly different from the negative control group(blank vector) (P<0.05). Let-7b-5p inhibitor down-regulated c-MYC mRNA m CONCLUSION Human acute myeloid leukemia cell line THP-1 low expresses the let-7b-5p, which regulates c-MYC expression through let-7b-5p-/FTO-/m

Objective To investigate the effect of continual care on postoperative medication compliance of patients with osteoporotic vertebral compression fractures (OVCF) after vertebroplasty.Methods A retrospective case control study was performed to analyze the clinical data of 150 patients with OVCF who underwent vertebroplasty in Guizhou People's Hospital from January 2016 to May 2017.There were 38 males and 112 females,aged 47-88 years,with an average of 67.5 years.Seventy-five patients were given continual care such as telephone follow-up and home visit (continual care group).Seventy-five patients were given routine health education (routine care group) when they were discharged from hospital.Visual analogue scale (VAS) and Oswestry dysfunction index (ODI) before operation,1 day,1,3,6 and 12 months after operation,as well as medication compliance and vertebral re-fracture at 1,3,6 and 12 months after operation were compared between the two groups.Results The preoperative VAS of the routine care group was 6 (6-7),1 (0-1),1 (1-3),2 (1-3) and 3 (2-5) points at 1 day and 1,3,6 and 12 months after operation,respectively.The preoperative ODI was 21 (18-27),0 (0-0),2 (1-4),5 (3-7),7 (5-10),10 (7-14) points at 1 day,1,3,6 and 12 months after operation.In the continual care group,VAS was 7 (6-7) points before operation,0 (0-1),1 (0-1),1 (0-2) and 2 (1-3) points at 1 day,1,3,6 and 12 months after operation,respectively.ODI of the continual care group was 18 (22-28) points before operation,0 (0-1),2 (0-4),4 (1-5),4 (3-6) and 6 (4-9) at 1 day,1,3,6 and 12 months after operation.The VAS and ODI of the two groups were lower than those before operation,and the scores of the continual care group were lower than those of the routine care group at 1,3,6 and 12 months after operation (P ＜ 0.05).The medication compliance rates of continual care group were 93％,89％,91％ and 84％ at 1,3,6 and 12 months after operation,while those of routine care group were 44％,40％,47％ and 40％ respectively (P ＜0.05).The incidence of vertebral re-fracture was 1％,1％,3％ and 3％ in continual care group and 3％,5％,5％ and 7％ in routine care group at 1,3,6 and 12 months after operation respectively (P ＜ 0.05).Conclusion Continual care can improve the medication compliance of OVCF patients after treatment with vertebroplasty,relieve pain,improve the quality of life,and reduce the incidence of vertebral re-fracture,which is worthy of clinical promotion.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.
