OBJECTIVETo improve the accuracy of preoperative evaluation of cervical lymph node metastasis in thoracic esophageal squamous carcinoma.

METHODSForty-two patients with thoracic esophageal squamous carcinoma underwent neck ultrasonography. Enlarged lymph nodes with their long axis greater than 10 mm and a short-to-long axis ratio greater than 0.5 were considered as metastatic.

RESULTSPreoperative neck ultrasonography revealed the enlarged lymph nodes in 16 patients, but only in 5 (31%) cases the nodes were palpable. Among them 9 were classified as metastatic (cM(1-LN)), including 4 patients with palpable nodes. In 5 cM(1-LN) patients surgical intervention was canceled and the remaining 37 patients underwent trans-thoracic esophagectomy. Cervical node metastasis (pM(1-LN)) was confirmed pathologically in 6 surgical patients, 4 with tumors invading the adventitia (pT3) and the other 2 into the surrounding structure (pT(4)) (pT(1), pT(2) vs. pT(3), pT(4), P = 0.020). All 6 pM(1-LN) patients had concomitant mediastinal node metastasis and 4 of them had upper abdominal node metastasis. Statistically significant relationship was detected between cervical and abdominal nodal status (r = 0.536, P = 0.007). In comparison with the results of pathological examination and treatment response, the accuracy and sensitivity were 81% and 95% (P = 0.043), 36% and 82% (P = 0.081), respectively, for palpation and ultrasonography. Five out of 39 (13%) patients had their therapy changed due to ultrasonographic findings.

CONCLUSIONSNeck ultrasonography for cervical lymphadenopathy is of high sensitivity and accuracy, which plays an important role in the preoperative evaluation and therapeutic decision-making.

OBJECTIVETo study DNA and nucleus damage in human embryo lung fibroblast (HLF) exposed to hydroquinone (HQ) and its genotoxicity.

METHODSHLF were treated with HQ (0, 10, 20, 40, 80 micro mol/L, respectively) for 3 h and DNA damage was detected by comet assay. HLF was also treated with the same concentrations of HQ for 1 h and micronucleus test was performed after they were cultured for 24 h.

RESULTSComet assay showed that percentage of cells with tails in each groups treated with varied doses of HQ was 12%, 19%, 42%, 79% and 95%, respectively, with mean tail length of 7.87, 9.35, 11.03, 19.28 and 23.32 micro m, respectively, in an obvious dose-dependent manner (P < 0.05). Very significant increase in percentage of cells with tails and length of their comet tail were observed in those groups treated with HQ of 20, 40 and 80 micro mol/L (P < 0.01). And, proportion of high and severe DNA damage increased with dose of HQ. HQ could also induce formation of micronucleus and abnormal nucleus in all groups treated by varied doses of HQ, with rates of micronucleus and abnormal nucleus of 2%, 3%, 10%, 9% and 15%, and 6%, 7%, 16%, 27% and 28%, respectively, in a significant dose-dependent manner. There was significant increase in rates of micronuclei and abnormal nuclei in cells treated with HQ at doses of 20, 40 and 80 micro mol/L (P < 0.05).

CONCLUSIONSExposure to HQ could cause DNA and nucleus damage inducing genotoxic effects on HLF.

OBJECTIVETo evaluate the incidence of Ketoconazole associated hepatotoxicity and related factor.

METHODSLiterature retrieval was conducted by using multi-databases for meta-analysis on Ketoconazole associated hepatotoxicity. The data were collected with a standardized form. Overall estimation of incidence of hepatotoxicity for specific study type was calculated by using a DerSimonian-Laird random-effects model owing to the substantial differences among the studies.

RESULTSTotally 204 eligible studies were included in the analysis. The incidence of Ketoconazole associated hepatotoxicity was 3.6%-4.2%. The dosage and duration specific subgroup analyses did not show any significant difference among groups, while the age specific subgroup analysis showed the incidence in children and people aged >60 years was 1.4% (95% CI: 0.5%-4.2%) and 3.2% (95% CI: 1.1%-8.7%) respectively. Additionally, the incidence of the hepatotoxicity was higher in people who had oral administration of ketoconazole beyond the provisions of the usage instructions, and the incidence was 5.7% (95% CI: 4.5%-7.2%).

CONCLUSIONKetoconazole associated hepatotoxicity was common. Off-label use might increase the risk of liver damage. Well-designed large sample studies are needed to identify the risk factors in future.
