Objective To investigate the role of the pulmonary function, arterial blood gas analysis, the St George respiratory questionnaire (SGRQ) score and nutritional status in evaluating the development of chronic obstructive pulmonary disease (COPD). Method Changes of the above-mentioned parameters were analyzed in hospitalized patients suffered from moderate to severe COPD and compared with parameters of those who had acute exacerbations when admitted to hospital. Results The forced expiratory volume in one second (FEV1)% pred and oxygenation index of the patients declined significantly with the development of the disease after one, two, three, four times in hospital [(68.43 ± 3.09)%, (61.27 ± 3.38 )%, (42.05 ± 4.16)%, (33.64 ± 3.34)% and 435.55 ± 10.23, 404.35 ± 11.56, 358.38 ± 13.21, 321.29 ± 11.78] (P < 0.05), while the level of PaCO2 increased significantly in moderate COPD [(36.23 ± 3.62), (45.44 ± 4.67), (57.82 ± 4.12), (78.28 ± 5.21 )mm Hg (1 mm Hg = 0.133 kPa) ] (P<0.05). The oxygenation index was declined significantly in severe COPD. The scores of SGRQ score declined significantly in all patients while the level of hemoglobin, albumin and body mass index did not change significantly. Conclusions Acute ex-acerbation attributes to the deterioration of pulmonary function and life quality of COPD patients. Monitoring the changes of pulmonary function, arterial blood gas analysis and SGRQ score may be useful in the evaluation of the development of COPD.

Gastric cancer can spread to the liver through hematogenous metastasis,lymphatic metastasis and serosal invasion of primary tumor.The occurrence of gastric cancer with liver metastasis is only second to the occurrence of peritoneal metastasis.Liver metastasis is one of the main distant metastasis of gastric cancer,and is a major cause of cancer-related death.The treatment of gastric cancer with liver metastasis still remains controversial.The optimal treatment strategies should be based on the clinicopathological characteristics of each patients and evidence-based medicine,and the individualized plan should be set through multidisciplinary team discussions.Before the more results of prospective studies released,multidisciplinary treatment is the main method,and the appropriate patients should be cautiously choosed for surgery.

In order to study the cause why the patients with psoriasis are susceptible to complicate with cardiovascular diseases, we have determined the levels of serum apolipoprotein A I, B 100, cholesterol and triglyceride in 30 cases of patients with psoriasis vulgaris by immunoquantitative, enzyme and triazole methods. The results showed that in comparison with the control group the levels of apolipoprotein A I and triglyceride were normal, the levels of apolipoprotein B 100 and cholesterol increased (both P

OBJECTIVE: To establish a HPLC assay for determining cassiaside B in rabbit plasma .METHODS: The proteinin sample was first denatured with methanol .The ?-- Bondapak C_(18) colurnn(3.9mm?300mm, 10?m) was used with a mobilephase of acetonitrile -- water -- THF -- glacial acetic acid(20:76.5:3.0:0.5) .The flow rate was 1.0ml/ min .Detecting wave-length was 278nm .RESULTS: The caliblation curve of cassiaside B was C=9.102?10~(-2)+4.871?10~(-5)R(r=0.9999) .Theaverage recovery of cassiaside B in plasma was (100.8?1.139)% .The relative standard deviations of intra -- day and inter -- dayassay were less than 2.08% .The detection limit in plasma was 0.05?g/ml .CONCLUSION: The method is sensitive and accu-rate. It is suitable for the pharmacokinetic study of cassiaside B.

The serine protease HtrA2/Omi is released from the mitochondrial intermembrane space following apoptotic stimuli.Once in the cytosol,HtrA2/Omi has been implicated in promoting cell death in caspase-dependent or caspase-independent pathway.On the other hand,HtrA2/Omi can refold and degrade misfolded proteins in the mitochondria during cell stress.

Objective To detect the change of precursor protein of sol in breast cancer before and after the neoadjuvant chemotherapy,so as to find the serum protein marker of chemotherapy drug resistance in breast cancer.Methods Breast cancer patients with Ⅲ period neoadjuvant chemotherapy were enrolled in the study.The serum specimens of the patients were obtained.Two-way gel electrophoresis was used to get the gel map before and after chemotherapy,then the image map was analyzed by gel analysis software.The differentially expressed proteins point was screened before and after chemotherapy.Serum protein differences were identified with matrix auxiliary laser disi ntegrate series time of flight mass spectrometer (MALDI-TOF-MS),including coagulation sol precursor protein.Western blot was used to test the variation trend of them before and after chemotherapy.Results Coagulation sol precursor protein levels fell after neoadjuvant chemotherapy in resistance group.The variation trend of the results of western blot and that of the proteomics were consistent.Conclusion Coagulation sol precursor protein can be as the candidate serum marker of chemotherapy drug resistance in breast cancer.

Objective To make clear of the mechanism of metastasis and recurrence of primary liver cancer, and to make sure of the preventive value of transeatheter arterial immun- ehemoembolization (ICE) in treatment of liver cancer. Methods The study is a double-blinded, controlled, prospective, randomized trial. 146 patients were randomly divided into 3 groups. Group A: regular surgery of primary liver cancer;group B: TACE 1month after surgery, treatment proposal was: ADM + DDP + 5-Fu + LP; group C:transeatheter arterial immun-chemoembolization 1 month after surgery, treatment proposal : ADM + DDP +5-Fu+LP+Octreotide+IFN. Results CD3+, CD4+, CD4+/CD8+ increased 1 month after surgery in group A; In group B: CD3+, CD4+, CD4+/CD8+ decreased but CD8+ increased 1 week after TACE; CD3+, CD4+, CD4+ /CD8+ increased but CD8+ decreased 4 weeks after TACE(P<0.05); In group C: CD3+ , CD4+, CD4+/CD8+ increased slightly 1 week after TACE, but increased significantly 4 weeks later(P<0.05). In group A, the level of VEGF was high before surgery but decreased 1 month after surgery; In group B, the level of VEGF decreased 1 week after TACE, decreased more significantly 4 weeks after TACE than that in group B(P <0.05). 1 year survival rate, 2 year survival rate and 3 year survival rate in group C ware higher than those in group A; 1 year survival rate was higher in group B than that in group A, however, 2 year survival had and 3 year survival rate had no differ-ences between group B and group A. Conclusion Transcatheter arterial ICE can prevent metastasis and recurrence after surgery of primary liver cancer increase the 1,2,3 year survival rate. It not only has the role of TACE,but can increase the immunefunction,and inhibit tumor angiogenesis, then increase the therapeutic effect.
