1.The attribution of acute exacerbation in the development of chronic obstructive pulmonary disease
Chinese Journal of Postgraduates of Medicine 2009;32(4):23-25
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.
2.Clinicopathological characteristics and treatment of stomach neoplasms with liver metastasis
Journal of International Oncology 2013;(4):290-293
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 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.

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 investigate the relationship between the CD+4 CDHigh25 regulatory T cells and cytokine IL-10 and acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Flow cytometric was used to detect the percentage of CD+4 CDHigh25Foxp3High Treg cell and CD+4 CDHigh25 CDLow127 Treg cell in CD+4 T cells and at the same time ELISA was used to test the serum IL-10 levels in corresponding period. Results 13 patients have received hematopoietic function reconstruction. aGVHD group of CD+4 CDHigh25 CDLow127/CD+4 and CD+4 CDHigh25 Foxp3High/CD+4 ratio were significantly lower than non-aGVHD group, the difference was statistically significant (P <0.01); Ⅲ-Ⅳ degree of aGVHD subgroup was lower than Ⅰ - Ⅱ degree of aGVHD subgroup, but no statistical significance(P >0.05); the same as between-group CD+4 CDHigh25 CDLow127/CD+4 and the CD+4 CDHigh25 Foxp3High/CD+4 has no significant difference;aGVHD group of IL-10 concentration was significantly lower than non-GVHD group, the difference was statistically significant (P <0.01). Treg cell and IL-10 changes in correlation, r = 0.557, P <0.05. Conclusion The level of Treg cell was closely related to the occurrence of aGVHD after allo-HSCT. So it is very important to monitor the Treg cell level for clinical early diagnosis of aGVHD and predict prognosis of aGVHD and guide the application of immunosuppressant. CD127 can serve as a Treg cell surface-specific marker, to promote the detection of Treg cell and purification. IL-10 was an important negative regulator. Treg cell and IL-10expression in patients with aGVHD was correlation, which may provide some basis for Treg cell immunosuppressive mechanism.
