OBJECTIVETo evaluate the efficacy and toxicity of Serratia marcescens (S311) vaccine in the treatment of malignant pleural effusion.
METHODSThirty-four patients with malignant pleural effusion were given S311 as intrapleural injection with a dose of 10(9) U (0.32 mg) on D 1, 8 and 15, and observed for four weeks.
RESULTSThe overall response rate (CR + PR) was 97.1% (CR in 12 patients and PR in 21 patients). The systemic toxicity was mild, including fever (82.4%), pleuritic pain (50.7%), nansea (26.5%), dyspnea (17.5%) and chills (5.9%).
CONCLUSIONSerratia marcescens vaccine is effective for malignant pleural effusion, with tolerable toxic effects. Further study is warranted.

BACKGROUNDTo evaluate the activity and toxicity of paclitaxel as second-line treatment for advanced non-small cell lung cancer (NSCLC).
METHODSForty patients with recurrent advanced NSCLC were enrolled. Thirty-six patients were managed with regular regimen. Paclitaxel 135 mg/m², 3 h, on day 1; DDP 75 mg/m² or carboplatin 300-350 mg/m² on day 2. Four patients were managed with weekly regimen. Paclitaxel 60 mg/m²,3 h, on days 1,8,15; DDP 75 mg/m² on day 2. It was repeated every three or four weeks, up to two to four cycles.
RESULTSThirty-six cases were evaluated for response and 27 for survival. The objective response rate was 13.9% (5/36). At least one tumor-related symptom relief was observed in 21 patients (58.3%). The median survival duration was 26.4 weeks and 1-year survival rate was 8% (4/36). The main toxicities included myelosuppression, fatigue and myalgia-arthralgia neuropathy.
CONCLUSIONSPaclitaxel has advantage to be well-tolerated and improve tumor-related symptom. Further studies with standardization of dose and regimen will be needed to clarify its role in the second-line treatment.

BACKGROUNDTo evaluate the efficacy, side-effects, median survival duration and survival rate of vinorelbine (NVB) combined with cisplatin (DDP) in the treatment of non-small cell lung cancer (NSCLC).
METHODSA total of 220 patients with inoperable NSCLC received NVB and DDP combined chemotherapy: NVB 25-30 mg/(m²*d) on days 1 and 5 (or 8), DDP 60-80 mg/(m²*d) on day 2. The schedule was repeated every 28 days. The efficacy and side-effects were analysed and followed-up after at least two cycles of chemotherapy.
RESULTSThe overall response rate (CR+PR) was 30.9% (68/220). The response rate was 31.3% (51/163) in initial treatment group, and 29.8% (17/57) in retreatment group. The median survival duration was 8.3 months. The 1-, 2- and 3-year survival rates were 39.23%, 19.31% and 6.32%, respectively. The main side-effects were myelosuppression and digestive tract reactions.
CONCLUSIONSVinorelbine plus cisplatin is an effective and well-tolerated regimen for non small cell lung cancer and myelosuppression is its dose-limiting toxicity.

OBJECTIVETo examine the influence of China's economic reforms on population health and regional mortality rates.
METHODSLongitudinal study measuring the mortality trends and their regional variations. Using data from the three most recent national censuses, we used the model life table to adjust the mortality levels within the population for each census, and to calculate life expectancy. We then examined the variation in patterns of mortality and population health by economic status, region and gender from 1980-2000.
RESULTSLife expectancy varied with economic status, province, and gender. Results showed that, although life expectancy in China had increased overall since the early 1980s, regional differences became more pronounced. Life expectancy for populations who live in the eastern coastal provinces are greater than those in the western regions.
CONCLUSIONDifferences in life expectancy are primarily related to differences in regional economic development, which in turn exacerbate regional health inequalities. Therefore, it is necessary to improve economic development in less developed regions and to improve health policies and the public health system that address the needs of everyone.

BACKGROUNDEndostar™ (rh-endostatin, YH-16) is a new recombinant human endostatin developed by Medgenn Bioengineering Co. Ltd., Yantai, Shandong, P.R.China. Pre-clinical study indicated that YH-16 could inhibit tumor endothelial cell proliferation, angiogenesis and tumor growth. Phase I and phase II studies revealed that YH-16 was effective as single agent with good tolerance in clinical use.The current study was to compare the response rate , median ti me to progression (TTP) ,clinical benefit andsafety in patients with advanced non-small cell lung cancer ( NSCLC) , who were treated with YH-16 plus vi-norelbine and cisplatin (NP) or placebo plus NP.
METHODSFour hundred and ninety-three histologically or cy-tologically confirmed stage IIIB and IV NSCLC patients , withlife expectancy > 3 months and ECOG perform-ance status 0-2 , were enrolledin a randomized ,double-blind ,placebo-controlled , multicenter trial ,either trialgroup : NP plus YH-16 (vinorelbine 25 mg/m² on day 1 and day 5 ,cisplatin 30mg/m² on days 2 to 4 , YH-167.5mg/m² on days 1 to 14) or control group : NP plus placebo (vinorelbine 25 mg/m² on day 1 and day 5 ,cis-platin 30 mg/m² on days 2 to 4 ,0.9% sodium-chloride 3 .75 ml on days 1 to 14) every 3 weeks for 2-6 cycles .The trial endpoints included response rate ,clinical benefit rate ,time to progression,quality of life and safety .
RESULTSOf 486 assessable patients , overall response rate was 35.4% in trial group and 19.5% in controlgroup (P=0 .0003) . The median TTP was 6 .3 months and 3 .6 months for trial group and control group respectively (P < 0 .001) . The clinical benefit rate was 73 .3 %in trial group and 64.0% in control group (P=0 .035) .In untreated patients of trial group and control group ,the response rate was 40 .0% and 23.9%(P=0 .003) ,the clinical benefit rate was 76 .5 % and 65 .0 % (P=0 .023) ,the median TTP was 6 .6 and 3 .7months (P=0 .0000) ,respectively .In pretreated patients of trial group and control group ,the response ratewas 23.9% and 8.5%(P=0 .034) ,the clinical benefit rate was 65.2% and 61.7%(P=0 .68) ,the median TTP was 5 .7 and 3 .2 months (P=0 .0002) ,respectively . The relief rate of clinical symptoms in trial groupwas higher than that of those in control group ,but no significance existed (P > 0 .05) . The score of quality oflife in trial group was significantly higher than that in control group (P=0 .0155) after treatment . There were no significant differences in incidence of hematologic and non-hematologic toxicity , moderate and severe sideeffects betweentrial group and control group .
CONCLUSIONSThe addition of YH-16 to NP regimen results in significantly and clinically meaningful improvement in response rate , median time to tumor progression,and clinical benefit rate compared with NP alone in advanced NSCLC patients . YH-16 in combination with chemotherapy shows a synergic activity and a favorable toxic profile in advanced cancer patients .
