Journal of International Oncology 2010;37(6):445-448
Deregulation of cell cycle is one of important mechanisms leading to breast cancer. It has been revealed that cyclin E and p27 are the most important regulatory factor for cell cycle control and a better marker for evaluating prognosis of breast cancer compared to other biological markers.

Objective To explore the clinical effect of ulinastatin on capillary injury improvement of renal syndrome hemorrhagic fever and renal leakage. Methods Patients were divided into 2 groups according to the random number table. The experimental group(25 cases)was given with ulinastatin and the control group(25 cases) was given 5% sugar solution as a blank control. All patients were treated with nutritional support ,rehydration , prevention of bleeding and other symptoms. In addition,according to the number of days of fever in the experimental group,the patients were divided into two groups. The experimental group A(9 cases)had fever 1 ~ 4 days;the experimental group B(16 cases)had fever 5 ~ 7 days. All patients were measured in microalbuminuria ,serum creatinine,plasma albumin and other clinical indicators after 7 day treatment. Results Compared with the control group,microalbuminuria of the experimental group was significantly decreased;Creatinine recovery rate was faster than that in the control group;Plasma albumin had significantly increased;The number of symptomatic days of concurrent perfusion of other tissues had also significantly reduced. Compared with the experimental group B , microalbuminuria of the experimental group A was significantly decreased;Creatinine recovery rate was faster than that in the experimental group B;Plasma albumin had significantly increased;The number of symptomatic days of concurrent perfusion of other tissues was also significantly reduced. Conclusion Ulinastatin could effectively treat vascular injury and syndrome due to capillary leakage caused by epidemic hemorrhagic fever virus ,and the best effect occurs in early application in the fever.

Objective To study the influence of Qingzao Runfei Huazhuo Xingxue decoction on pulmonary tissue and lung function in mouse model of lung injury induced by PM2.5, and to provide an idea of clinical prevention and treatment of respiratory diseases induced by PM2.5. Methods Totally 30 clean level male ICR mice were randomly divided into three groups: normal control group, model group and Qingzao Runfei Huazhuo Xingxue decoction intervention group, with 10 mice in each group. Model of PM2.5-induced respiratory disease in mice was reproduced by instilling nasal cavity drip PM2.5 suspension 40 mg/kg once a day for 6 weeks. In the treatment group, the mice were fed with the Qingzao Runfei Huazhuo Xingxue decoction twice a day from the 4th week of instilling PM2.5 suspension until the end of experiment. In the normal control group, the mice were fed as usual. At the end of the experiment, the total protein content in bronchoalveolar lavage fluid (BALF), and lung wet/dry weight (W/D) ratio was determined. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes in lung tissue under light microscope. The inflammatory mediators levels in lung tissue were determined by antibody-sandwich enzyme linked immunosorbent assay (ELISA). Results Respiratory system damage model was successfully reproduced by dripping of PM2.5 suspension in nasal cavity. Compared with normal control group, inflammatory changes and inflammatory cell infiltration in model group were significant, and lung W/D ratio (4.71±0.33 vs. 3.13±0.12), total protein content in BALF (mg/L: 363.98±18.24 vs. 82.13±12.78), tumor necrosis factor-α [TNF-α (ng/L): 185.72±0.23 vs. 31.03±0.16], interleukin-8 [IL-8 (ng/L): 531.85±37.83 vs. 72.64±16.72], and leukotriene B4 [LTB4 (ng/L): 931.74±48.64 vs. 483.81±41.74] in lung tissue were significantly increased (all P < 0.05). Compared with the model group, the inflammatory changes of lung tissue in Qingzao Runfei Huazhuo Xingxue decoction intervention group were significantly reduced, lung W/D ratio (3.92±0.41 vs. 4.71±0.33), total protein content in BALF (mg/L: 213.21±19.62 vs. 363.98±18.24), TNF-α (ng/L: 124.15±0.27 vs. 185.72±0.23), IL-8 (ng/L: 238.42±35.82 vs. 531.85±37.83) and LTB4 (ng/L: 582.85±31.00 vs. 931.74±48.64) levels in lung tissue in Qingzao Runfei Huazhuo Xingxue decoction intervention group were significantly decreased (all P < 0.05). Conclusion Qingzao Runfei Huazhuo Xingxue decoction can improve PM2.5-induced damage and pathological inflammatory changes in lung tissue, which provided some new ideas for the treatment of PM2.5-induced respiratory diseases.

Objective To detect the expression of Cytokeratin 19 (CK19) and human mammaglobin (hMAM) mRNA in the peripheral blood of breast cancer patients dynamically and to evaluate its clinical significance.Methods The expression of CK19 and hMAM mRNA was evaluated by real-time fluorescent quantitative reverse transcriptase pelymerase chain reaction in the peripheral blood of 40 breast cancer patients and 10 healthy volunteers.Results The expression of CK19 and hMAM in the peripheral blood of 40 breast cancer patients were higher than healthy donors.The positive expression rate of CK19 and hMAM was descending tendency during treatment.The different staging expression rate had no differences between before treatment and during treatment,but after treatment the expression rate had remarkably differences (CK19:P=0.044;hMAM:P=0.005).If the expression of CK19 and hMAM was continual positive,the rate of recurrence and metastasis would be higher (P<0.001).Coneluslons Real-time fluorescent quantitative RT-PCR may detect the expression of CK19 and hMAM in the peripheral blood of breast cancer patients,and it is a sensitive and specific technique.The resuits suggest a possible use of this approach for evaluating prognosis,monitoring recurrence.

Aim To investigate the effect of Tetramethylpyrazine (TMP) on the proliferation of airway smooth muscle cells (ASMCs). Methods Primary ASMCs of rats were cultured. The absorbance (A490) value of ASMCs treatment with platelet-derived growth factor (PDGF) in the presence of TMP was detected by MTTto observe the anti-proliferation of TMP. The levels of ERK1/2 and p-ERK1/2 proteins were determined by Western blot.Results In presence of the TMP with different concentrations (12.5,25,50,100 and 200 ?mol?L-1) at 6,12,24,36 and 48 hours,compared with control groups,the average inhibitory rates of cell proliferation in all groups were increased significantly (P

Objective To examine the advanced oxidation protein products (AOPP) in patients with acute coronary syndrome(ACS) and discuss the relationship between oxidative stress with the development of atherosclero-sis(AS). Methods Plasma were collected in 59 acute myocardial infarction (AMI) patients including 35 patients underwent selective PCI,24 patients underwent emergency PCI,43 unstable angina pectoris(UA) patients and 10 non-coronary artery disease (non-CAD) patients. All cases underwent coronary angiography (CAG). Plasma was collected immediately,post-24 hours and post-48 hours after admission. AOPP was determined by measurements of absorbance (A) at 340 nm under acidic conditions via spectrophotometry. Results AOPP was (236.42±30.41) ( n = 35 ), ( 207.84±29.50 ) mmol/L ( n = 35 ), ( 227.79 ± 35.18 ) mmol/L ( n = 31 ) respectively immediately, post-24 hours and post-48 hours after admission in AMI ( selective PCI ), ( 239.95 ±39.94 ) mmol/L ( n = 43 ), (175.92 ±29.46) mmol/L(n =38) ,and (156.54 ±28.29) mmol/L(n =35) in UA group and (57.41 ± 13.60) mmol/L( n = 9 ), (56.11 + 11.90) mmol/L ( n = 10 ) and ( 61.75 ± 12.28 ) mmol/L ( n = 8 ) in non-CAD group. Compared with normal group ( without CAD ) , significantly higher plasma AOPP was detected in AMI ( selective PCI) and UA patients ( P < 0.05 ). AOPP level was significantly increased in AMI selective PCI patients as compared with that of emergency PCI group immediately and post-24 hours after admission( P <0.01 ) ,and post-48 hours after admission( P < 0.05 ), but there was no statistical significance between emergency PCI and UA group( P > 0.05 ). Conclusions Oxidative stress is an important step in the development of atherosclerosis, and the higher levels of AOPP in ACS patients show that AOPP may be as good markers in these patients.
