1.0~(?)1.5 cm(14.81%)(P=0.10).There was no lymph node metastasis in tumors less than 1.0 cm in diameter. The 5-year survival rates for cases with or without lymph node involvement were 92.31% and 60.0%,respectively,the difference was significant(P=0.000).The 5-year survival rates of 12 patients showing ground-glass opacity(GGO)on chest CT was 91.67% without any lymph node involvement.Conclusions:There is mediastinal and hilar lymph node involvement even with tumor diameter less than 2 cm.The results of the present study suggested that routine lymph node dissection is necessary even for cases with tumor diameter less than 2 cm.However,if the tumor is within 1.0 cm in diameter with obvious GGO showing on chest CT,these are good candidates for partial resection without mediastinal lymph node dissection.

Genuine medicinal materials with special characteristics of Traditional Chinese Medicine (TCM), is recognized as high quality medicine. Both ancient records and modern research considered that the origin is an important reason for the formation of genuine medicinal materials. However, blindly transplanting of genuine medicinal materials has led to the quality decline and counterfeit medicines appeared in production or sale progress, which may increase the risk of accidents in TCM. Frequent accidents emerged in Chinese herbal affects its export. What's more, it is a great threat to the medication safety in TCM clinical. There is an urgent need to implement traceability systems of TCM, which could provide convenient information record and traceability of TCM circulation. This paper reviews a variety of technical methods for genuine medicinal materials traceability, and proposed the establishment of genuine medicinal materials traceability system based on two-dimensional code and network database.

Objective To confirm the distribution of high arsenic drinking water and the situation of endemic arsenism in Hubei Province, to provide reference basis for prevention and control of endemic arsenic disease. Methods Using typical investigation and sample investigation in 2006 and 2007, the arsenic content of water was detected sampled from 19 counties(cities or communities). And those water samples which were close to or exceeded the stipulated standard were rechecked by the national standard method. Furthermore, the situation of endemic arsenism was investigated in the cities having high arsenic contents of water. Results In 2006,10 028 water samples of 446 villages in 6 counties (cities or communities) were tested, the wells of high arsenic (> 0.05 mg/L) were found in 5 counties (cities or communities) and the proportion of the well that exceeded stipulated standard was 5.29%(530/10 028); In 2007,19 086 water samples of 1282 villages in 17 counties(cities or communities) were tested, the wells of high arsenic were found in 11 counties(cities or communities), and the proportion of the well that exceeded stipulated standard was 1.74%(333/19 086). In these two years, 29 114 water samples were tested, in which 863 water samples were exceeding the stipulated standard. The 2.96% of total wells exceeded stipulated standard and mainly distributed in 179 villages of 12 counties(cities or communities). And the highest arsenic content of water sample was 2.012 mg/L. In the endemic arsenism area, 2 critical, 1 moderate and 1 mild arsenism patients had been found. Conclusions The water of high arsenic content are scattered in Hubei Province and the situation of endemic arsenism disease is mild. Improving water aiming at decreasing arsenic and establishing patient files should be carried out immediately.

OBJECTIVETo evaluate the effect of Feiji Recipe (FJR) on quality of life (QOL) of patients with non-small cell lung cancer (NSCLC).
METHODSOne hundred and two patients with NSCLC were randomly assigned into 2 groups. The 61 patients in the combined treated group were given FJR and chemotherapy and the 41 patients in the control group were treated with chemotherapy alone. They were observed for two treatment courses with QOL estimated by EORTC QLQ-C43 questionnaire and FACT-L questionnaire, the two international questionnaires as the tools for measurement, and referred to the traditional evaluating indexes of clinical efficiency.
RESULTSQOL in the combined treated group was improved after treatment with the improvement of scores in all domains, including functional and symptom sub-domain, while it in the control group deprived significantly, showing significant difference between the two groups (P < 0.05). Similar results were also shown in the evaluation of physical performance by Eastern Cooperative Oncology Group (ECOG) and Karnovfsky performance scoring. The gastrointestinal reaction and myelo-suppression were slighter in the combined treated group than those in the control group (P < 0.05), and no significant difference was shown between the response rate of the two groups (P > 0.05).
CONCLUSIONFJR can improve QOL of patients with NSCLC, reduce the adverse reaction of chemotherapy, and improve patients' physical performance.

Objective This study was designed to investigate the expression changes of osteopro-tegerin (OPG), tartrate-resistant acid phosphatase (TRAP) and vascular endothelial growth factor (VEGF) mRNA in collagen induced arthritis(CIA) rats. Methods After CIA was induced in Sprague-Dawley rats, the experimental animals were treated with PBS or rAAV-EGFP or rAAV-hOPG (100 μl/day) intra-articular injection for 10 days. Messenger RNAs (mRNAs) were obtained from CIA synovium 40days after first immun-ization. Reverse transcriptase-polymerase chain reactions (RT-PCR) were carried out to detect the mRNA encoding OPG, TRAP, VEGF and β-actin, which acted as inner control. The genes detected clearly by RT-PCR were quantified using real-time PCR. Results The expression of all genes was confirmed by specific single bands in RT-PCR. Real-time PCR showed that the expression levels of TRAP and VEGF were increased, whereas those of OPG mRNA were decreased in CIA group compared with normal controls. The intra-articular gene transduction markedly increased the gene copies of OPG by 128.21% (P<0.01). The expression change of OPG in synovium also caused the decrease of the expression levels of TRAP and VEGF by 58.79% (P<0.01)and 17.85% (P>0.05) respectively, however, the expression change of VEGF was not statistically significant. Conclusion OPG gene mediated by rAAV can be successfully tranfered to knee joint synovium in vivo. The results of this study suggest that gene transfer using rAAV-OPG may be a feasible and effective therapeutic approach to treat or prevent joint destruction in inflammatory arthritis.

OBJECTIVETo establish a methodology of protein misfolding cyclic amplification (PMCA) and utilize in the detection of PrP(Sc) in brain tissues from prion diseases.
METHODSDifferent amounts of Scrapie 263K agent bulk were mixed with brain homogenates of health hamsters and treated with repeated incubation/sonication for 10 to 15 cycles. The proteinase K-resistant PrP(Sc) was evaluated with Western Blot.
RESULTSIn this experimental situation, 263K agent replicated rapidly in vitro, utilizing hamsters' brains as the medium. With the established PrP(Sc)-PMCA technique, PrP(Sc) signals in the preparations containing less than 10(-5) diluted 263K bulk could be detected. Compared with conveniently used immuno-blot assay, the sensitivity of PrP(Sc)-PMCA for PrP(Sc) was 10(5) to 10(6)-fold increased. It has been also shown that homogenates of cerebellar and brain stem could be used as the medium for PrP(Sc) replication.
CONCLUSIONA rapidly replicating method for PrP(Sc), PrP(Sc)-PMCA, was successfully established, providing a new approach for early diagnosis of prion diseases and research on the biological features of prion.

OBJECTIVETo investigate the relationship between the vasoactive substances including endothelin-1 (ET-1), calcitonin gene-related peptide (CGRP), and nitric oxide (NO) in myocardium and the cardiac functions in chronic renal ischemia rats.
METHODSMale Wistar rats weighting 180-200 g were randomly divided into 2 groups: operation group (n=30) and sham operation group (n=10). A ligation of abdominal aorta between right and left renal artery was made by silk suture in operation group and the necrosis degree of aorta was about 50%. Aorta was not ligated in sham operation group. Sixteen weeks after operation, invasive measurement of blood pressure and cardiac function were performed, and content of ET-1, CGRP, and NO in myocardium were determined.
RESULTSCompared with sham operation group, blood pressure significantly increased in the operation group after ligation, along with decreased cardiac systolic and diastolic function, increased left ventricular mass index. After 16 weeks, compared with sham operation group, the content of ET-1 in cardiac tissue were significantly elevated in operation group [(361.0+/-118.7) vs. (503.4+/-139.6 ) pg/ml, P<0.01), along with significantly decreased CGRP content [(74.4+/-24.8) vs. (45.4+/-15.1) pg/ml, P<0.01). The content of ET-1 in cardiac tissue was negatively correlated with the maximum pressure rise rate of left ventricular r=-0.37, P<0.05).
CONCLUSIONSChronic kidney ischemia caused by abdominal aorta ligation may result in the increase of ET-1 content in cardiac tissue and decrease of CGRP decreased. The content of ET-1 in cardiac tissue is also negatively correlated with left ventricular systolic function.
