4. CLINICAL APPLICATION OF AXIAL LOAD MECHANICAL TESTING IN REMOVING EXTERNAL FIXATOR AFTER TIBIA AND FIBULA FRACTURES SURGERY
Chinese Journal of Reparative and Reconstructive Surgery 2016;30(9):1085-1088
OBJECTIVE: To explore the efficacy and safety of the axial load mechanical testing for removing external fixator. METHODS: Between January 2014 and August 2015, 27 patients with tibia and fibula fractures caused by trauma underwent an external fixation. Of 27 patients, 21 were male and 6 were female with the average age of 45 years (range, 19-63 years), including 7 cases of closed fracture and 20 cases of open fracture. X-ray film results showed spiral unstable fracture in 4 cases and comminuted unstable fracture in 23 cases. All patients underwent an external fixation. Bone nonunion occurred in 3 cases because of infection, and bone nonunion combined with bone defect occurred in 1 case, who received tibial osteotomy lengthening surgery. When X-ray film showed continuity high density callus formation at fracture site, axial load mechanical test was performed. If the axial load ratio of external fixator was less than 10%, the external fixator was removed. RESULTS: At 21-85 weeks after external fixation (mean, 44 weeks), axial load mechanical test was performed. The results showed that the axial load ratio of external fixation was less than 10% in 26 cases, and the external fixator was removed; at 6 weeks after removal of external fixator, the patients could endure full load and return to work, without re-fracture. The axial load ratio was 14% in 1 case at 85 weeks, and the X-ray film result showed that fracture did not completely heal with angular deformity; re-fracture occurred after removing external fixator, and intramedullary fixation was used. CONCLUSIONS: External fixator axial load mechanical testing may objectively reveal and quantitatively evaluate fracture healing, so it is safe and reliable to use for guiding the external fixator removal.

Objective: To study the dynamic changes of type Th22 cell immunological response during atherosclerosis process in experimental mice in order to provide a new theoretical basis for atherosclerosis therapy. Methods: 8 weeks C57BL/6J mice were divided into 2 groups: Experiment group,n=24 ApoE-/- mice and Control group, n=24 normal mice. All animals received high fat diet and the following indexes were compared between 2 groups at 0, 4, 8, 12 weeks after treatment: aortic atherosclerotic lesions were deifned by Oil red O staining, dynamic changes of Th22 cells in spleen were measured by lfow cytometry, mRNA expressions of interleukin-22 (IL-22), IL-22R1, AhR and T-bet in aorta were examined by RT-PCR, blood levels of IL-22 was detected by ELISA. Results: Compared with Control group, Experiment group had the increased area of aortic atherosclerosis (the ratio of plaque area/lumen area) and Th22 cell (CD4+ IL-22+/CD4+T cell) amount, elevated mRNA expressions of IL-22, IL-22R1, AHR, T-bet in aorta and higher blood levels of IL-22 at all time points, the differences between each time point (except 0 week) had the statistic meaning,P<0.05. In Experiment group, the differences between 2 adjacent time points, for the area of aortic atherosclerosis and mRNA expressions of AHR, T-bet: 4 weeks vs 0 week, 8 weeks vs 4 weeks, 12 weeks vs 8 weeks all had statistic meaning; for Th22 cell amount: 4 weeks vs 0 week, 8 weeks vs 4 weeks had statistic meaning and 12 weeks vs 8 weeks had no real distinction; for mRNA expressions of IL-22, IL-22R1 and blood levels of IL-22: 4 weeks vs 0 week had statistic meaning and 8 weeks vs 4 weeks, 12 weeks vs 8 weeks had no real distinctions. Conclusion: Hyperactive immunological response of Th22 cells might be involved in atherosclerosis process, the relevant mechanism should be further studied.

Objective To investigate the value of urinary neutrophil gelatinase-associated lipocalin (NGAL) and liver-type fatty acid-binding proteins (L-FABP) in early diagnosis of acute kidney injury (AKI) after liver transplantation. Methods During 2007-2008, 25 liver transplant recipients were recruited. Blood and urinary samples were collected before operation and at 2, 4, 6,12, 24, 48, 72, 120 h after portal vein opening, and used to determine serum creatinine (Scr), as well as urinary NGAL and L-FABP, which were normalized to urinary creatinine. According to the Acute Kidney Injury Network (AKIN) criteria of AKI, all the patients were divided into AKI and non-AKI groups. Standard statistics were used along with ROC analysis to evaluate the diagnose value of selected markers. Results There were no significant differences in clinical parameters between non-AKI (n=14) and AKI (n=11) groups. Both groups had a transient rise in Scr 2-12 hours after surgery, but the rise lasted longer in AKI patients (2-24 hours). While urinary L-FABP rose transiently in both groups 2-120 hours following surgery, urinary NGAL was only slightly elevated at 2 h in the non-AKI group, but rose and stayed high from 2 to 6 h in the AKI group.ROC analysis revealed that NGAL (cut-off 43.02, 26.97 and 17.19 ng/mgCr, AUC 0.766, 0.773 and 0.773 at 2, 4 and 6 h, respectively) was better than L-FABP (cut-off 3451.75 ng/mgCr, AUC 0.760 at 4 h). Conclusion Urinary NGAL appears to be a sensitive and specific marker of AKI in liver transplant recipients, but these data need to be validated in larger prospective studies.

Objective:To investigate the diagnostic value of vaginal color Doppler flow parameters in patients with epithelial ovarian cancer in different FIGO staging.Methods:178 patients with ovarian tumors who were treated by surgery in Dingzhou People’s Hospital from Jul. 2016 to Jul. 2022 were selected, and they were divided into ovarian cancer group (65 cases) and ovarian cyst group (113 cases) according to the results of postoperative pathological diagnosis. According to FIGO staging standards, ovarian cancer was divided into FIGO stage I (18 cases) , FIGO stage II (16 cases) , FIGO stage III (16 cases) and FIGO stage IV (15 cases) . The blood flow parameters of vaginal color Doppler ultrasound were measured, including arterial pulsatility index (PI) , end diastolic flow velocity (EDV) , resistance index (RI) , peak flow velocity (PSV) , serum vascular endothelial growth factor (VEGF) and human epididymal epithelial secretory protein 4 (HE4) . The levels of PI, EDV, RI, PSV, VEGF and HE4 were compared between the two groups and patients with different FIGO stages, and the value of ROC analysis of vaginal color Doppler flow parameters in predicting the occurrence of ovarian cancer was analyzed. The correlation between FIGO stage and vaginal color Doppler flow parameters and serum VEGF and HE4 levels was analyzed by person coefficient.Results:PI and RI levels in ovarian cancer group were (0.79 ± 0.15) , and (0.39 ± 0.12) , lower than those in ovarian cyst group (1.51 ± 0.17) , (0.72 ± 0.16) ; EDV, PSV, HE4, VEGF levels were (13.88 ± 4.18) cm/s, (25.61 ± 4.53) cm/s, (283.92 ± 28.97) pmol/L, and (372.55 ± 38.96) ng/mL, higher than those in ovarian cyst group ( P<0.05) . According to ROC analysis, the best cutoff values of transvaginal color Doppler blood flow parameters for predicting the occurrence of ovarian cancer were PI<1.235, EDV≥10.985 cm/s, RI<0.580, PSV≥22.975cm/s, all P<0.05. The levels of PI and RI in patients with different FIGO stages showed a decreasing trend with the increase of the severity of the disease, while the levels of EDV, HE4 and VEGF showed an increasing trend ( P<0.05) . There was no significant difference in PSV levels between patients with different FIGO stages ( P>0.05) . The correlation analysis showed that FIGO stage was positively correlated with the blood flow parameters EDV and the levels of serum HE4 and VEGF. FIGO stage was negatively correlated with PI and RI ( P<0.05) . Conclusions:There were significant differences in the levels of PI, RI and EDV in patients with ovarian cysts and ovarian cancer at different FIGO stages. The levels of PI, RI and EDV are closely related to the malignant degree of ovarian cancer.
