AIM: To explore the variation of blood biochemistry and arterial blood gas of patients with systemic inflammatory response syndrome (SIRS) in the early time after trauma and improve the diagnosis and first aid. METHODS: Eighty-eight patients with trauma from August 2003 to February 2004 were divided into two groups by their AIS-ISS90 score. The data of temperature, pulse, respiratory rate, white blood cell counts, Hb, blood glucose and arterial blood gas (PaO 2, PaCO 2, HCO 3 -, AG) were collected and compared with each group by statistic methods. RESULTS: Of the 88 patients, 49 underwent SIRS, 12 in light trauma group (ISS≥16) and 37 in severe trauma group (ISS45 mmHg or 0 05). 13 patients had MODS in severe trauma group and 2 died while none had MODS or died in light trauma group. CONCLUSION: Application of AIS-ISS90 and SIRS-related blood biochemistry and arterial blood gas is beneficial for the diagnosis and treatment for patients in the early time after trauma. [

Objective To investigate whether or not the pulmonary artery participates in the blood supply of lung cancer and its change of morphology and blood flow in lung cancer. Methods Two different colors of silicone were injected separately into the bronchial and pulmonary arteries of 33 rat models with squamous cell carcinoma of lung. The origin of blood supply of lung cancer and the morphologic change of pulmonary artery were observed under a stereomicroscope. The DSA of bronchial and pulmonary artery were performed simultaneously in 28 patients with lung cancer. Results The pulmonary branch of rat and patients were reduced, thinned and occluded in the affected lung. The pulmonary artery did not form tumor vessel, and pulmonary blood flow and perfusion were reduced or absent in the affected area. Conclusion The pulmonary artery didn′t participate in the blood supply of lung cancer. It is unreasonable to perform transcatheter chemo embolization for lung cancer via pulmonary arteriay.

Objective To study the effect of Chinese Herb of Yigan Granules in different dosages on bile secretion in rats.Methods The rats were randomly divided into 5 groups: blank control group,positive control group and high,mod erate,low dosages of Yigan Granules groups.The medicines were administered thr ough duodenal intubation for the rats.Then the volume of bile were gathered by common bile duct intubations in different time,and the volume of bile and the contents of bilirubin in bile were tested before and after given drugs.Results Yigan Granules increased the bile secretion in a dose-dependent manner and promote the secretion of bilirubin.Conclusion Chinese Herb of Yigan granules has a choleretic effect.

OBJECTIVE To discuss the feasibility of signal amplification method with cationic conjugated polymers(liposome) applied during the detection of Pseudomonas aeruginosa using piezoelectric gene biosensors.(METHODS) Oligonucleotide probe for P.aeruginosa was immobilized on the surface of gene sensor array and(hybridized) by PCR production of P.aeruginosa.After hybridization,liposome was added.The frequency shifts were recorded and compared with those ones of the control groups.RESULTS The frequency shifts were(significantly) increasing when adding liposome and the compatible concentration of liposome was 0.8?g/?l.(CONCLUSIONS) Liposome signal amplification is proved to be an effective method to amplify the piezoelectric(signal).

Objective To investigate the correlation between the D-dimer level and the acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods The changes of D-dimer levels in 156 patients (AECOPD group) before and after treatment were measured and compared with the D-dimer levels of 156 healthy subjects(control group).Results The concentration of plasma D-dimer in the AECOPD group was (1.35 ± 1.46) mg/L,which was significantly higher than (0.25 ± 0.16)mg/L in the control group,and the difference was statistically significant(t =9.354,P ＜0.05).The level of plasma D-dimer in the AECOPD group was (0.69 ± 0.87)mg/L,and compared with (1.35 ± 1.46)mg/L before treatment,the difference was statistically significant(t =4.850,P ＜ 0.05).Conclusion D-dimer level is correlated to the condition of patients with chronic obstructive pulmonary disease,it can be used as one of the indicators to diagnose whether a patient is in hypercoagnlable state or suffers thrombotic diseases.

Aim To investigate the enhancing effect of L-carnitine as a sensitizer on tumor necrosis factor-re-lated apoptosis inducing ligand ( TRAIL)-induced ap-optosis in glioma cells. Methods Glioma cell U87 was used as model cell line. Cell viability was determined by CCK-8 , and apoptosis was assessed by Annexin V-FITC/PI staining, caspase-3 activity and expres-sion. The expression and transcription of nuclear factor kappa B ( NF-κB ) and FLICE inhibiting protein ( c-FLIP) were measured by RT-PCR and Western blot. In addition, NF-κB was knockdown to analyze its regu-lating effect on c-FLIP expression. Results The com-bination treatment with TRAIL and L-carnitine signifi-cantly inhibited cell proliferation and induced apopto-sis. Compared with control, combinational treatment significantly suppressed the transcription and expres-sion of c-FLIP as well as translocation of NF-κB. Through silencing NF-κB, NF-κB was found to act as upstream signaling to regulate c-FLIP. Conclusion L-carnitine sensitizes TRAIL-induced tumor cell apoptosis via suppression of NF-κB-dependent c-FLIP expres-sion.

Objective To study the expression and signficance of the osteopontin (OPN) in epithelial ovarian cancer tissue and serum. Methods Immunohistochemistry method and ELISA were used to detect the expression of OPN in 64 cases of epithelial ovarian cancer tissue and serum, 20 cases of ovarian benign tumors and 10 cases of ovarian nomal tissues. Results The OPN expression was associated with the clinical staging and histological grading of epithelial ovarian cancer tissue and serum (P < 0.01). The level of OPN in epithelial ovarian cancer tissue was significantly higher than that in benign ovarian tumor and normal control groups (P < 0.01). Conclusion OPN is remarkably correlated with the carcinogenesis and the development of epithelial ovarian cancer.
