Objective To identify risk factors associated with the severity of acute kidney injury (AKI) in-duced by crush syndrome and whether the patient required hemodialysis (HD). Method A retrospective study was designed. Within 19 days after the Chinese Wenchuan earthquake (May 12, 2008), 63 victims (33 men, 30women) of 2139 cases were hospitalized at Mianyang Central Hospital (Siehuau, China) because of crush syn-drome caused by crush injuries. The patients with renal dysfimcfion before the earthquake were excluded. Totally 63 patients with AKI associated with crush syndrome were included in this study and were divided into two groups: group 1, 25 patients, requiring HD (when urine volume <250 mL/d;serum potassium> 6 mmol/L) ; and group 2, 38 patients, without HD. The following data were collected retrospectively for all patients: (1) epidemiological parameters: age, gender, race, time under the rubble, liquid treatmem before being rescued; (2) clinical param-eters: blood pressure, body area crushed, amputation, fasciotomy, blood transfusion, quantity of fluid infusion, urine output in the first 24 hours; (3) initial laboratory data: complete blood count, urine analysis, serum chem-istry, arterial blood gas analysis. Comparisons between the two groups were made using SPSS 10.0. The quantita-tive data and categorical data were analyzed using t tests and χ2 tests, respectively. P -values < 0.05 were consid-ered to indicate significant differences. The significant variables were entered into logistic regression models to de-termine the risk factors for the severity of AK1 in patients with crush syndrome and whether the patient required HD. Results Four significant risk factors with P -values < 0.05 were identified: fasciotomy, cystatin C (Cys C)level, myoglobin (MB) level and lactic acidosis. The odds ratios (95% confidence intervals) were 8.641 (3.027～76.479), 6.956 (3.027～76.479), 5.379 (3.027～76.479) and 4.833 (2.569～32.764), respectively. Conclusions In addition to urine output and potassium levels, we found that four risk factors, namely faseiotomy, Cys C and MB levels, and lactic acidosis, were significanfly associated with the severity of AKI and whether the patient required hemodialysis.

Objective To study the CT findings of ovarian sertoli-leydig cell tumor (SLCT),to improve the understanding of SLCT imaging features.Methods CT images of 6 cases were reviewed retrospectively.CT plain scan was performed in 6 patients;CT enhancement scan was performed in 4 patients.Results All tumors were unilateral.On non-enhanced CT,5 cases showed cystic-solid masses with clear margin,and 1 case showed solid mass.After contrast administration,the cystic walls,septum and solid portions showed progressively obvious enhancement.Of these 6 cases, 3 cases showed increased testosterone levels,2 cases had high prolactin level,and 1 case was with raised AFP in plasma.Positive expressions of immunohistochemical markers were as following:Inhibin-α (6 cases),Vimentin (4 cases),Calretinin (2 cases), CD99 (1 case), Ki-67 (1 case), CK20 (1 case).Conclusion CT findings of SLCT have some certain characteristics, especially a unilateral, cystic-solid and well-defined mass, and marked solid part enhancement on contrast CT.Combined with clinical findings, especially increased plasma testosterone levels, SLCT should be included in the differential diagnosis of regional tumors.

Objective To explore the mechanism of skeletal fluorosis via observation on the expression of bone γ-carboxyglutamic acid-containing protein (BGP) and osteoprotegerin (OPG) in the residents of coal-burning fluorosis regions, and to provide a basical data for further monitoring and evaluating the effects of fluoride-reducing projects. Methods Stratified sampling was applied, the 6 villages of fluorosis were chosen as focusing areas for investigation. The residents of villages underwent clinical examination of the skeletal fluorosis. And according to the degree of skeletal fluorosis, villages were divided into three groups, namely light, moderate and severe villages. Radio-Immunoassay and Enzyme-linked immunosorbent assay were used to check the expression of BGP and OPG in the serum. Results The levels of serum BGP in the severe skeletal fluorosis cases[(6.78±4.43)μg/L] were significantly higher(P<0.05) than those in the normal, moderate and the severe groups [ (3.58±1.53), (3.44±2.66), (3.41±2.20)μg/L], respectively. The expression of OPG in the light, moderate and the severe groups [(1251.55±998.31), (1265.94±931.77), (1560.55±858.07)ng/L] were significantly higher (P<0.05) than those in the normal[(520.81±385.05)ng/L], respectively. The levels of BGP in mixed type[(6.09±2.62)μg/L] were much higher(P<0.05) than no mixed type[(3.97±1.53), (3.20±2.12)μg/L]. The levels of OPG in the osteosclerosis, osteoporesis and mixed type[(1321.63±1017.00), (1205.42±852.22), (1529.01±402.83)ng/L] were significantly higher(P<0.05) than those of the normal, respectively. The levels of OPG in the light villages [(452.06±338.10)ng/L] were significantly lower(P<0.05) than moderate and severe villages[(1266.30±899.14), (1851.80±956.08 )ng/L], respectively. The levels of OPG in the severe villages were significantly higher(P<0.05) than moderate villages. Conclusions It indicates that OPG can be used as an early indicator in coal-burning pollution endemic fluorosis results in biochemical changes in the composition of bone.

OBJECTIVETo investigate the role of CCL28 in hypoxia-induced cell migration of hepatocellular carcinoma (HCC).

METHODSResected liver tissues from 50 HCC patients were subjected to real-time (rt)-PCR analysis to evaluate the mRNA expression levels of the hypoxia-induced factor HIF-1a and the chemokine CCL28. Patient data on treatment and outcome were analyzed. The human HCC cell lines HepG2 and HCCLM3 were used to investigate effects of hypoxic conditions on HIF-1a and CCL28 expressions by rt-PCR, western blotting, and enzyme-linked immunoassay. The CCL28-mediated effects of hypoxic conditions on cell mobility and invasion were assessed by trans-well and matrigel assays, respectively, in HCCLM3 with CCL28 expression silenced by small-interfering (si)RNA transfection. Spearman's rank test was used to assess the correlation between CCL28 and effects on disease- and treatment-related factors.

RESULTSThe mRNA levels of CCL28 (0.025 +/- 0.075) were found to be strongly correlated with HIF-1a(0.065 +/- 0.098) in human clinical samples of HCC (r = 0.595, P less than 0.01), with higher expressions of both related to recurrence after surgery (P = 0.011 and 0.019, respectively). In vitro hypoxic conditions stimulated HIF-1a and CCL28 expression in a time-dependent manner in both HepG2 (HIF-1a: F = 873.5; CCL28: F = 151.6) and HCCLM3 (HIF-1a: F = 964.5; CCL28: F = 285.8) (all P less than 0.01). siRNA inhibition of CCL28 in HCCLM3 cells led to a significant reduction in hypoxia-induced invasion and migration (all P = 0.011).

CONCLUSIONChemokine CCL28 expression is up-regulated in human HCC and under in vitro hypoxic conditions, and may play an important role in hypoxia-induced HCC migration and invasion.
