OBJECTIVETo study the therapeutic effects of posterolateral depression fractures of the tibial plateau through a modified anterolateral approach.

METHODSFrom February 2011 to January 2012,13 patients with posterolateral depression fractures of the tibial plateau were treated through a modified anterolateral approach. There were 8 males and 5 females, ranging in age from 28 to 59 years old (49.2 years old on average). Data from patients were collected retrospectively as follows: X-ray, time of fracture healing and the complications of fracture healing. The patients were evaluated both clinically and radiologically according to the Rasmussen score system.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months (mean 13.7 months). All the patients got bony union. The average radiographic bony union time was 15.1 weeks (ranged, 11 to 17 weeks). No case of secondary articular depression was found. No complications such as malunion or joint stiffness were found. But 1 patient had superficial infection and 1 patient had common peroneal nerve injury. According to the Rasmussen score system,the mean radiological score was 16.50 ± 0.67 (ranged, 13 to 18), and the mean functional score was 25.20 ± 2.21 (ranged, 13 to 30). The mean range of knee motion was (125.3 ± 9.3)° (ranged, 0° to 135°).

CONCLUSIONTreatment of depression fractures of posterolateral tibial plateau with a modified anterolateral approach is a safe method with effective exposure, due to its stable fixation and relatively good outcome with minimal soft-tissue complications. It is regarded as an ideal procedure for depression fractures of posterolateral tibial plateau.

Objective: To quantitatively evaluate the abnormal tense of parasympathetic nerve via measuring the heart rate deceleration capacity (DC) and heart rate variability (HRV) in patients with vasovagal syncope (VVS).
Methods: Our research included 2 groups: VVS group,n=28 patients with positive head-up tilt test treated in our hospital from 2013-06 to 2014-08 and Control group,n=30 patients without cardiovascular disorders. The DC and HRV were examined and compared between 2 groups.
Results:① The overall deceleration capacity (ODC) (9.4 ± 2.9) ms and daytime deceleration capacity (DDC) (8.9 ± 2.9) ms in VVS group were higher than those in Control group (7.5 ± 2.5) ms and (7.5 ± 2.5) ms respectively,P<0.05.② More patients in VVS group presented daytime-to-nighttime deceleration capacity ratio (DNratio) >1 than those in Control group (9/28, 32.1% vs 2/30, 6.7%),P=0.019.③ The SDNN (139.8 ± 34.0) ms, SDSD (29.9 ± 15.7) ms and rMSSD (40.9 ± 18.8) ms in VVS group were higher than those in Control group, (115.5 ± 29.4) ms, (21.8 ± 6.6) ms and (28.9 ± 8.4) ms respectively,P<0.05.④ Multivariate Logistic regression analysis indicated that ODC was positively related to vasovagal syncope occurrence (OR=2.045, 95% CI: 1.100-3.801,P=0.024).
Conclusion: VVS patients have abnormally increased indexes of DC and HRV, HDC is the predictor for vasovagal syncope occurrence.

OBJECTIVETo analyze the specificity, sensitivity and receiver operating characteristic (ROC) curve of plasma elafin for diagnosis of skin acute graft-versus-host disease (aGVHD), and to explore its clinical diagnostic value.

METHODSIncidence of skin aGVHD from fifty-three patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) were observed prospectively in Guangdong General Hospital from Apr 2010 to Aug 2011. The plasma concentrations of elafin were detected by enzyme-linked immunosorbent assay (ELISA). Skin biopsies were taken from 28 patients with skin rash, and elafin expression in the skin was detected by immunohistochemistry. Positive expression was defined as significant staining of at 50% of the depth of the epidermis, excluding the granular cell layer and the acrosyringium.

RESULTSAmong 28 patients with skin rash, twenty-five were considered as skin aGVHD by clinical diagnosis, seventeen were confirmed as skin aGVHD by pathological biopsy. 11 cases were elafin positive by immunohistochemical staining. Elafin protein was overexpressed in aGVHD skin tissue (P = 0.001). Plasma concentrations of elafin were significantly higher in patients with skin aGVHD (positive) group than in those without skin aGVHD (negative) group (P = 0.005), among which there being no statistically significant difference in plasma elafin level between patients with grade I skin aGVHD group and negative group(P = 0.971), but being statistically significant difference compared patients with grade II-IV skin aGVHD group with those with grade I skin aGVHD group (P = 0.02) and with negative group (P = 0.008). Using the pathological diagnosis as the gold standard, the estimated specificity and the sensitivity of clinical diagnosis criteria were 27.3% and 100%, respectively, and those of tissue elafin protein level were 100% and 64.7%, respectively. The area under the ROC curve was 0.909 (0.797 - 1.021) when plasma concentrations of elafin was used in diagnosis of skin aGVHD. The sensitivity was 82.4% and the specificity was 81.8 % when the critical value was set at 1456.043 µg/L.

CONCLUSIONPlasma concentration of elafin is significantly higher at the onset of skin aGVHD. It can be used as biochemical marker of skin aGVHD and has higher value in diagnosis of skin aGVHD.

This study was purposed to investigate the efficacy and safety of intravenous injecting itraconazole (ITCZ) as empirical antifungal therapy in the patients with hematological malignancies. According to recommendation in IDSA guidebook, the patients suffered from fever during neutropenia and inefficacy of treatment using broad-spectrum antibiotics for 4 days should receive intravenous injection of ITCZ as empirical antifungal therapy. The results showed that the overall clinical response rate to ITCZ injection was 62.9% (22/35), and the success rate of achieving composite endpoints was 54.3% (19/35). Mild adverse reactions were observed in 6 patients (17.1%). The injection of ITCZ was stopped in 2 patents (5.7%) due to adverse reaction. Further analysis revealed that the response rate was higher in patients with fever prior to the start of ITCZ within five days than beyond five days (P = 0.031). The response rate was higher in patients with possible invasive fungus infection (IFI) than that in patients with probable and confirmed IFI (P = 0.002). The prophylactic antifungal treatment during neutropenia displayed no significant influence on efficacy of empirical antifungal therapy with itraconazole (P = 0.054). It is concluded that the good efficacy and safety of empirical ITCZ injection for hematological malignancies patients is efficient and safe.

The aim of this study was to investigate the renal function in 149 patients receiving myeloablative allogeneic hematopoietic stem cell transplantation (allo-HSCT) from June 2005 to June 2010 in our hospital, and analyze the risk factors resulting in kidney insufficiency and experience in diagnose and therapy. The creatinine clearance (CrCL) and serial creatinine level were evaluated before and after allo-HSCT within 100 days and 1 year. Non-radiation conditioning regimens were used for any patients. The acute kidney insufficiency (AKI) was defined as at least a 1.5-fold rise in serum creatinine level after allo-HSCT within the first 100 days. The chronic kidney insufficiency (CKI) was defined as the creatinine clearance < basal level within 3 months to 1 year after allo-HSCT. The results showed that the kidney insufficiency was found in 41 patients, in which the incidence of AKI was 32/149 (21.5%). CsA, amphotericin B (P = 0.025) and ES (P = 0.022) were defined as risk factors for AKI. The incidence of CKI was 18/138 (13%). cGVHD (P = 0.013) and TA-TMA (P = 0.012) were associated with the development of CKI. The 2-year survival was lower in patients with kidney dysfunction than that in patients without kidney dysfunction (39% vs 74.1%, P < 0.001). The main factors resulting in kidney insufficiency were defined as infection (52%), GVHD (20%), TA-TMA (12%) and tumor relapse (12%). It is concluded that kidney insufficiency is an important complication of allo-HSCT. Careful monitoring kidney function, minimizing the use of amphotericin B, prophylaxis and effective treatment of fungal infection, GVHD and TA-TMA may be effective preventive measures to decrease the incidence of kidney insufficiency.

OBJECTIVETo evaluate the effects of cervical vertebrae degeneration on traumatic cervical cord injury.

METHODSFrom January 2009 to December 2010, 24 patients with cervical cord injury without obvious fractures and dislocations were treated with operation, and their data were retrospectively analyzed. Among them, 16 males and 8 females, aged from 46 to 70 years old with an average of 59.1 years. Patients were divided into light degeneration group (6 cases), moderate degeneration group (10 cases) and severe degeneration group (8 cases), according to the preoperative degenerative degree of cervical vertebrae. Preoperative neurological dysfunction and postoperative neurological recovery were compared according to the JOA scores of Japanese Orthopaedic Society; quality of life were evaluated according to SF-36 scale (36-item Short Form Health Survey, SF-36).

RESULTSAll patients were followed up from 4 to 16 months with an average of 12 months. The JOA score of light, moderate, severe degeneration group were 12.1 +/- 1.5, 10.3 +/- 1.8, 7.3 +/- 1.0, respectively; and were respectively increased to 16.3 +/- 1.0, 15.3 +/- 1.4, 13.0 +/- 2.3 at the 3 months after operation. Postoperative JOA score showed the improvement rate of mid-long-term neurological level was light degeneration group (89.8%) > moderate degeneration group (76.6%) > severe degeneration group (58.8%). The results of preoperative SF-36 scale showed light degeneration group > moderate degeneration group > severe degeneration group; there was significant difference in comparison of two groups (P < 0.05 ).

CONCLUSIONCervical degeneration is an important pathologic basis and risk factor in traumatic cervical cord injury, and the degenerative degree will directly influence the injury degree and prognosis of neurological function, the clinical relationship between them should be sufficiently paid attention to.
