Objective To investigate the relationship between insulin like growth factor (IGF Ⅰ)、IGF Ⅱ and IGFBP 3 and Child Pugh classification in patients with liver cirrhosis and to determine the potential clinical markers of functional hepatic reserves. Methods Forty four patients with posthepatitic cirrhosis were divided into 3 groups according to disease severity (Child Pugh Score) and 38 healthy subjects severed as controls. Serum levels of IGF Ⅰ, IGF Ⅱ and IGFBP 3 were measured in these groups by immunoradiometric assay. Results Baseline IGF Ⅰ, IGF Ⅱ and IGFBP 3 levels were significantly lower in patients with cirrhosis than in controls, and the serum concentrations of IGF Ⅰ, IGF Ⅱ and IGFBP 3 were associated with the marked changes of liver function due to Child Pugh score. They all showed a significant correlation with the degree of hepatic dysfunction and dropped markedly during the progression of liver failure. The sensitivity of IGF Ⅱ is much higher than that of IGF Ⅰ and IGFBP 3. It was found that IGF Ⅰ

Objective To investigate the effect of specialized human tel omerase antisense oligodeoxyribonucleotides (AS-ODN) on the growth inhibition o f well, moderate and poor differentiated gastric cancer cell lines, and to explore its inhibitory mechanism and the correlation between the inhibition ratio of gastric cancer cells and differentiation of the tumor cells. Methods Under the given circumstances, three distinct differentiated gastric cancer cell lines were treated with AS-ODN. The telomerase a ctivities were measured by modified telomeric repeat amplification protocal assa y. The cell viability was detected by Trypan blue test, and the cell apoptosis was determined by cell morphological observation under light and electromicroscope, flow cytometry an d TUNEL assay. Results The telomerase activity and cell growth were apparently suppressed in MK N45 and SGC7901 cells, under defined concentrations of AS-ODN. Whilst, in MKN28 cells, only telomerase activity was suppressed at same concentration . There were no obvious changes in non-antisense oligomers treated group. The apoptotic features of MKN45 and SGC7901 were noticed by microscopic observa tion, TUNEL assay, after three distinct gastric cancer cell lines being continuo usly exposed to 10 ?mol/L AS-ODN for 96 h. Furthermore, the flow cytometric analy sis verified that the average apoptotic rate of MKN45 and SGC7901 was 44.75% and 33.56% respectively, but there were no obvious changes in non-antisense oli gomers treated group (P

Fifty four patients with chronic sinusitis (without nasal polyps) were randomly divided into two groups. Thirty patients in experimental group were treated with dirithromycin and 24 patients in control group were treated with clarithromycin. The doses was both 250 mg q. d. and the duration of treatment was 3to 6 months. The VAS scores of subjective symptoms (nasal obstruction, purulent nasal discharge,headache, smell worse ) and Lund-Mackay scores of objective signs (sinus CT ) in both groups were improved significantly compared with the baseline(P ＜0.05), and there were no statistical significances between two groups ( P ＞ 0. 05 ). The curative effect was positively correlated with the duration of treatment.The total effective rates were 73% and 67% and adverse reaction rates 7% and 21% in two groups,respectively (P ＞ 0. 05 ); but the adverse reactions in control group were more serious than those in experimental group. During the six-month follow-up, no recurrence and aggravation were observed. The results suggest that low-dose dirithromycin may be more suitable for long-term treatment of chronic sinusitis.

Objective To evaluate the brain invasion in gliomas by diffusion tensor tractography(DTT).Methods Diffusion tensor imaging was preoperatively performed in 35 patients who histologically confirmed gliomas.13 of the 35 tumors were low-grade gliomas and 22 were high-grade gliomas. Then the spatial relationship between the lesions and white matter fiber tracts around tumor was analyzed. displacement, continuity and injured conditions of white matter fiber were observed. Results White matter fiber tract in all lesions could be observed clearly. Three patterns of white matter fibers involvement were identified:displaced,infiltrated and destructed. White matter fiber tracts around low-grade gliomas were primarily displaced ,but were mainly infiltrated and destructed around high-grade gliomas. Conclusion DTT was useful for showing white matter fiber tracts,observing the shape changes stereographically,and evaluating the relationship with gliomas in vivo.

Objective To study the short-term clinical efficacy of treating patients with advanced gastrointestinal cancer with lentinan injection and javanica oil emulsion injection.Methods Clinical information of 42 patients with advanced gastrointestinal cancer were retrospectively collected.The 42 patients were divided into two groups according to treatments,with 21 case in the control group who were treated with javanica oil emulsion injection,as well as 21 case in the treatment group treated with lentinan injection and javanica oil emulsion injection.The efficacy,quality of life (QOL) and adverse effects were observed after treatment for 3 weeks.Results 81.0％ (17/21)of patients in the treatment group improved in QOL,which was much higher than that in the control group 47.6％ ( 10/21 ) ( x2 =5.081,P =0.024 ).The objective remission rate was 19.0％ (4/21)and 14.3％ (3/21)in the treatment group and the control group respectively,with no significant differece bwtween the two groups( x2 =0.171,P =0.679 ).the disease control rate was 85.7％ (18/21)in the treatment group,which was significantly higher than that of 61.9％ (12/21)in the control group( x2 =4.200,P =0.040 ).The incidence of adverse effect related to hematological toxicity,liver and kidney function,the digestive tract and itching of skin were similar between the two groups (Ps ＞ 0.05 ).Phlebitis in the treatment group was not as frequent as that in the control group(P ＜0.05).Conclusion Treating patients with advanced gastrointestinal cancer with lentinan injection and javanica oil emulsion injection had high efficacy than treating only with javanica oil emulsion injection,and it improved QOL signifiantly with safety.

Objective To explore the clinical efficacy of treating pains suffered from metastatic bone cancer with composite kushen injection and pamidronate disodium injection.Methods The clinical information of 60 cases of metastatic bone cancer patients suffered with pains was collected retrospectively.Thirty patients were assigned to the treatment group and 30 to the control group according to the treatment they underwent.The control group were treated with pamidronate disodium injection for 3 cycle,the treatment group were additionaly treated with composite kushen injection.The differences of two groups cases were compared in respect of the relief of pains and the changes of performance status (PS) and the incidence of adverse effects after treatment for 3 cycles.Results The objective remission rate of bone pain was 60.0％ (18/30) in the treatment group,which was significantly higher than that of 30.0％ (9/30) in the control group was higher( x2 =5.455,P=0.020 ).The incidence of adverse effect was 40.0％ (12/30) in the treatment group and 46.6％ (14/30) in the control group,with no significant difference between the two groups( x2 =0.271,P =0.602).In the treatment group the performance status of patients was( 2.30 ± 0.70 ) after treatment,which was better than that of( 1.80 ± 0.80 )before treatment(t =15.000,P =0.042),wheras there was no significant difference on performance status in the control group.Conclusion Kushen injection has synergistic effect with pamidronate disodium injection in treating pains with matstatic bone cancer.It could improve the short term efficacy,and significantly relief the pain and improve the quality of life.

The research of sleep staging is not only the basis of diagnosing sleep related diseases, but also the precondition of evaluating sleep quality, and has important clinical significance. In recent years, the research of automatic sleep staging based on computer has become a hotspot and made some achievements. Feature extraction and feature classification are two key technologies in automatic sleep staging system. In order to achieve effective automatic sleep staging, we proposed a new automatic sleep staging method which combines the energy features and least squares support vector machines (LS-SVM). Firstly, we used FIR band-pass filter to extract the energy features of Pz-Oz channel sleep electroencephalogram (EEG) signals, and compared them with those from wavelet packet transform method. Then we designed an LS-SVM classifier to realize the automatic sleep stage classification. The research showed that FIR band-pass filter (with the Kaiser window) performed better than wavelet packet transform (WPT) for energy feature extraction just in terms of the data from the Sleep-EDF Database and the LS-SVM classifier (with the RBF Kernel function) designed was good, and the automatic sleep staging method proposed in this paper was better than many similar methods from other studies with an average accuracy of 88.89% and had a very prosperous application future.
