In order to evaluate the applied value of soluble intracellular adhesion molecule-1 (sICAM-1) in acute rejection (AR) following liver transplantation, the expression of sICAM-1 protein was sequentially detected by using ELISA in serum and bile of 43 patients receiving liver transplantation. In AR group, the expression levels of sICAM-1 protein were increased 3 days before and immediately on the establishment of AR diagnosis, and there was significant difference in the expression of bile between AR group and control group (P<0.01). After reversion of AR with hormone intensive therapy, there was significant difference in the sICAM-1 protein expression of serum and bile between AR group and control group. It was concluded that the sequential detection of sICAM-1 protein level in serum and bile was a reliable and noninvasive method for the early diagnosis of AR after liver transplantation and was valuable to observe the curative effects of anti-AR therapy.

A rapid and simple flow-injection-catalytic spectrophotometric method using stopped-flow technique for determination of trace phenols is described. This methods is based on the catalytic effect of phenols on the reaction of rhodamine B and potassium bromate in sulfuric acid medium. The optimal experimental conditions are obtained by using the controlled and weighed centroid simplex method. The linear range of the determination is 0.60～4．00 mg/L for phenols, and the detection limit is 0.1 mg/L with the sample throughput of 34/h. The relative standard deviation of eleven replicate measurements is less than 2.0%. It has been applied for the determiantion of phenols in waste water with satisfactory results

A rapid and sensitive flow-injection spectrophotometric method was proposed for the determination of metoclopramide. This method was based on the diazotisation of metoclopramide with sodium nitrite in acidic medium and coupling with α-naphthylamine. The optimal experimental condition was obtained by using the simplex optimization method. The linear range was 0.0 ～ 30 mg/L, and the sample throughput was 160 samples h-1. The relative standard deviation of eleven replicate measurements was less than 0.6%. The method was used to determine metoclopramide in tablets and injections. The results were statistically compared with those obtained by pharmacopoeia method.

Objective To understand the source of knowledge on schistosomiasis prevention and control and the acceptable degree on different propagation patterns of population in Jingjiang City after schistosomiasis transmission?interrupted,so as to provide the evidence for the production of suitable materials for health education. Methods The permanent residents,floating population as well as the primary school students in Grade 5 and 6 in riverside regions in Jingjiang City were selected as the in?vestigation objects,the information propagation condition and the knowledge source,and the expected propagation patterns were investigated by questionnaires. Results The popularizing rates on the television,computer and mobile phone of the villag?ers were 99.81%,84.16% and 87.78%,respectively. Both the two investigated schools had the independent TV network,broad?cast and multimedia,and all the computer classroom could connected to Internet. The main sources on schistosomiasis control of permanent residents and floating population were folders and the exhibition board(62.0% and 40.5% respectively),the substan?tial material(42.0% and 33.5% respectively)and TV(40.5% and 36.0% respectively),while those of the students were video CD(100%),substantial material(99.5%)and folders and the exhibition boards(84.2%). The propagation ways with high ac?ceptable degrees among the residents and floating population were substantial material,folders and the exhibition boards and short messages by mobile phone,while those among the students were video CD,substantial material,folders and the exhibition boards. Conclusion The material on health education should be targeted to the demands of the different populations and their condition of information propagation,in addition,the Internet material should be developed and the communicational channels should be broaden.

Objective To evaluate the clinical value of early intervention of second-line treatment for advanced breast cancer patients who experienced elevated tumor marker without any evidence for progress on imaging after effective first-line treatment. Methods We recruited 42 metastatic breast cancer patients experiencing elevated tumor marker (CEA or CA-153) meanwhile, who had merely increased tumor markers again in regular review after effective first-line treatment. Patients were divided into two groups: 20 patients in treatment group were given second-line treatment (palliative chemotherapy); 22 patients in observation group insisted on regular follow-up without any changing of treatment strategy. We mainly evaluated PFSmarker , which was defined as the time between tumor markers increase and disease progression. Results CEA and CA-153 in patients with advanced breast cancer showed a tendency to decrease after first-line chemotherapy , which can be reduced again by second-line treatment while increased in regular review , and the observation group continued to rise until disease progressed. The PFSmarker in treatment group was 13.65 (6 ~ 24) months while that of the observation group was 8.18 (3 ~ 15) months. The difference of PFS between these two groups was statistically significant (P < 0.05) and the median time to disease progression in treatment group was significantly longer than that in observation group. Conclusions Early intervention of second-line treatment for advanced breast cancer patients who only experienced elevated tumor marker after effective first-line treatment could slow down disease progression and improve the quality of life.

Objective:To investigate the role of anaphylatoxin C 5 a in patients with asthma .Methods:A prospective study was performed between September 2006 and February 2007.A total of 33 patients with acute exacerbation of asthma and 13 healthy subjects were recruited into the study .The patients with acute exacerbation of asthma were also studied when they returned to the remission state .Levels of lung function, levels of C5a in induced sputum and cell differential count in induced sputum were determined . Results:The level of C5 a in induced sputum was significantly higher in patients with acute exacerbation of asthma [0.85(0.68-2.13) μg/L] than that in patients with stable asthma [0.45(0.26-0.88)μg/L, Z=-2.193, P=0.013];Sputum C5a levels in stable asthma patients were significantly higher than those in healthy controls [0.14(0.06-0.45) μg/L, Z=-2.141, P=0.015].The level of C5a in patients with severe exacerbation [2.21(1.27 -9.0) μg/L] was significantly higher than those in patients with mild exacerbation [0.34(0.17-0.63) μg/L] and moderate exacerbation [0.85(0.55-1.67) μg/L,χ2 =12.330, P=0.001].The level of C5a in induced sputum was positively correlated with the number of total cells count (r=0.797, P=0.004), neutrophils (r=0.504, P=0.032) and macrophages ( r =0.424, P=0.036 ) in acute exacerbation of asthma .Conclusion: C5a levels in induced sputum could be identified as an important prognostic biomarker , which involved in asthma ’ s pathogenesis .

Objective:To investigate the changes and clinical implications of serum procalcitonin in exacerbation of chronic obstructive pulmonary disease(COPD).Methods:We have evaluated PCT measurement in 45 patients with an exacerbation of COPD(group A) and 25 patients with stable COPD(group B),quantitative sputum culture was performed,too.PPMs were only regarded as significant if they reached a growth of ≥10~7cfu/mL,indicating the presence of bacterial infection.Results:In patients with an exacerbation,15 patients,sputum yielded a high(≥10~7cfu/mL) bacterial load(group A_1),30 patients,sputum yielded a low(0.05).Using a cut-off point of 0.155?g/L for PCT,the sensitivities and specificities for bacterial infection in patients with an exacerbation of COPD were 93.3% and 60% respectively.Conclusion: Serum procalcitonin measurements in patients of an exacerbation of chronic obstructive pulmonary disease play a role in the diagnosis of bacterial infection.
