ObjectiveTo study the influence of preoperative transcatheter arterial chemoembolization (TACE) on liver resection in patients with resectable hepatocellular carcinoma (HCC).MethodsTACE was performed before liver resection in 62 out of 126 patients, and perioperative risk factors were compared with that of the 64 patients without TACE including liver perioperative function alterations, average blood loss during operation, the average time of clamping porta hepatis and operation, abdominal drainage at 1-, 2-, and 3-days post-op, mortality and morbidity. ResultsThere was not significant difference in liver function alteration in the two groups, there was no mortality in the two groups. Liver cirrhosis in TACE group was more serious than that in no TACE group, the operation time was longer in TACE group. Blood loss, and abdominal drainage were much more in TACE group than in no TACE group. However postoperative complications did not differ.Conclusion Preoperative TACE for resectable HCC increases surgical difficulty and risk. Preoperative TACE for resectable HCC needs to be used on baseis of strict selection.

Objective: To study the influence of preoperative transcatheter arterial chemoembolization (TACE) by selection on survival rate of resectable hepatocellular carcinoma (HCC) patients. Methods: Jan. 1996 to Jan. 1997, TACE was performed before surgery in 62 of 126 patients undergoing resection and the other 64 patients without TACE from. Results were retrospectively analyzed with regard to the changes of pathological examination after operation, recurrence rate and survival rate 1, 2, 3 years after operation. Results: Pathological examination showed that there were 13 total necrosis in TACE group, but no one in contrast group. There were no significant difference of recurrence rate 1, 3 years after operation between 2 groups. Recurrence rate 2 years after operation was 29.8% in TACE group, but 58.3% in contrast group. There were significant difference of recurrence rate 2 years after operation between 2 groups (P<0.05). Survival rate 3 years after operation was 54.4% in TACE group, but 33.3% in contrast group. Survival rate of TACE group was higher than that of contrast group (P<0.05). There were not significant difference of recurrence rate 1, 2 years after operation between 2 groups. Conclusion: Proper preoperative TACE for resectable HCC can improve the outcome of the operation to some extent.

OBJECTIVETo evaluate the acute effects of indoor and outdoor particulate matter on lung function and respiratory symptoms of college students in winter.

METHODSA panel of 37 college students aged 19-21 in Wuhan were included and the investigation was carried out from 12/23/2009 to 01/05/2010. Daily morning/evening forced expiratory volume in one second (FEV1) and respiratory symptoms (cough, phlegm and runny) were measured and reported by subjects, respectively. Meanwhile, daily data of indoors and outdoors PM10, PM2.5, temperature, and relative humidity were collected. Generalized Estimating Equations (GEEs) were used to estimate the association between particulate matters exposure and respiratory symptoms and FEV1).

RESULTSAverage daily concentrations of indoor, outdoor PM2.5 during the study period were (110.6 ± 42.3), (143.5 ± 51.2) µg/m³, (148.2 ± 43.2) and (239.1 ± 71.3) µg/m³ for indoor, outdoor PM10, respectively. Outdoor exposure to PM2.5 on lag 0 had little effect on evening FEV1). However, researchers observed a significant lagging effect (lag 1 d) and accumulative effect (lag 0-1 d and lag 0-2 d). A rise in the PM2.5 concentration of 10 µg/m³ resulted in the change of evening FEV1) of -0.28% (95% CI: -0.52%, -0.03%), -0.45% (95% CI: -0.81%, -0.08%) and -0.63% (95% CI: -1.15%, -0.11%), respectively. For respiratory symptoms of coughing up phlegm, 10 mg/m³ increase of indoor/outdoor PM2.5 concentration were associated with odds ratio of 1.18 (95% CI: 1.02-1.36) and 1.08 (95% CI: 0.97-1.19), respectively. Moreover, risk of coughing up phlegm increased with lagging time, and accumulative time of indoor and outdoor PM2.5 and PM10.

CONCLUSIONOur study suggested that short-term exposure to particulate matters in winter was significantly associated with acute changes of respiratory symptoms and FEV1) of college students in Wuhan. Moreover, the effects of particulate matters tended to be larger as the increase of lagged and accumulative days.
