Objective To study the changes in PAF and its receptor in Kupffer cells in experimental cirrhosis and to evaluate the role of activated Kupffer cells in portal hypertension. Methods Kupffer cells, isolated from the livers of control and CCl_4-induced cirrhotic rats, were cultured in serum-free medium overnight. PAF synthesis and release by Kupffer cells were determined 24 h later by rapid ~3H-PAF scintillation proximity assay, and the expression of PAF receptor in Kupffer cells by saturation binding technique and semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR). By immunohistochemisty, the distribution of PAF in Kupffer cells was surveyed. Results Cell-associated PAF synthesis and release was increased about 1.48 fold and 2 fold, respectively, by Kupffer cells in cirrhotic liver as compared with the control (P0.05). Consistent with the receptor binding capacity, the mRNA expression of PAF receptor increased significantly in the Kupffer cells of cirrhotic liver (P

Objective To investigate the correlation between Kupffer cells and the synthesis of platelet activating factor(PAF)in experimental hepatic cirrhosis,and to elucidate the effects of endothelin(ET)on portal hypertension.Methods Thirty SD rats were randomly assigned to two groups:control group and CCl4-induced hepatic cirrhotic group.Kupffer cells,isolated from the livers of animals in both groups,were cultured for 24h.ET-1-induced PAF synthesis,and mRNA expression of PAF,ET-1 receptor and preproendothelin-1 in Kupffer cells were determined by rapid 3H-PAF scintillation proximity assay,saturation binding technique and semi-quantitative reverse transcriptase polymerase chain reaction(RT-PCR),respectively.Results Cell-associated PAF synthesis and release increased about 1.48 folds and two-folds,respectively,by cirrhotic Kupffer cells as compared to the control(1.02 ? 0.06 vs 0.69 ? 0.07 pg /mg DNA in Kupffer cells and 1.42? 0.14 vs 0.66 ? 0.04 pg/mg DNA in medium).Endothelin-1 enhanced Kupffer cells to stimulate PAF synthesis in a concentration-dependent manner,and for cirrhotic Kupffer cells,the effect was more significant than control.Cirrhotic Kupffer cells also had increased densities of functional receptors for both PAF and ET-1(exclusively ETB),but did not change the affinity of these receptors.No mRNA transcripts for the ETA receptor or preproET-1 were detected.Conclusion Kupffer cell is the main source of PAF in the cirrhotic rats.ET-1 stimulates PAF synthesis in activated Kupffer cells via ETB receptor.Since both ET-1 and PAF individually cause portal hypertension,Kupffer cells may play a role in portal hypertension associated with liver cirrhosis.

Objective To observe the effect of Aquacel AG dressing in treating diabetic foot and nursing measures.Methods Seventy-nine hospitalized patients diagnosed as diabetic foot were enrolled,and 45 of them were chosen randomly as the experimental group,who was treated with Aquacel AG dressing,and changed the dressing per 3 to 5 days.The other 34 patients were named as the control group,who was treated with normal cotton dressing by wet compress,and changed the dressing one time per day.The total effective rate and healing condition were compared between the two groups.Results The total effective rate of the experimental group was 93.3％,higher than that of the control group (79.4％) significantly.The healing time of the experimental group was (64±10)days,shorter than that of the control group,(88±12)days.Conclusions Aquacel AG dressing was suggested to use in treating diabetic foot.

Objective To investigate the significance of metastasis associated lung adenocarcinoma transcript 1 (MALAT1) in the occurrence and development of non-small cell lung cancer(NSCLC).Methods Eighty-six NSCLC lung tissue samples and 86 corresponding adjacent tissues were collected.Real-time quantitative polymerase chain reaction (RT-PCR) was used to detect MALAT1 mRNA expression.The correlation analysis of the gender,age,carcinoma embryonic antigen (CEA),clinical stage,and the degree of differentiation was performed.Results MALAT1 expression levels showed an average 2.16-fold increase in NSCLC lung tissues(87.23 ±9.72) when compared with adjacent tissues(40.38 ± 5.49),the difference was statistically significant (t =7.894,P ＜ 0.01).There was no significant difference between gender,age,histological type,tumor diameter,CEA level in terms of MALAT1 expression (P ＞ 0.05).There was significant differences between pathological stage (Ⅰ stage =52.38％ (11/21),Ⅱ stage =76.00％ (19/25),Ⅲ stage =97.50％ (39/40),x2 =11.839,P =0.042),tumor differentiation (High differentiated =39.13％ (9/23),moderately differentiated =74.47％ (35/47),low differentiated =100％ (16/16),x2 =15.383,P =0.032)and lymph node metastasis (with =97.22％ (35/36),no =46.00％ (23/50),x2 =23.947,P =0.030).Conclusion MALAT1 might be involved in the development of NSCLC,and could be an auxiliary diagnosis marker.

Objective To evaluate the therapeutic effect,safety and complication of percutaneous argon-helium cryoablation in the treatment of primary hepatocellular cancer(HCC).Methods Three hundred HCC patients were treated with percutaneous argon-helium cryoablation under ultrasound guidance with argon-helium cryosurgical system.Results Two hundred and thirty-three tumors(diameter ranged from 5.0cm to 15cm,with a mean of 7.2cm?2.8cm),in 165 patients were considered to be incompletely ablated,while 185 tumors(diameter ranged from 1.9cm to 7.0cm with mean value of 5.6cm?0.8cm) in 135 patients were completely ablated.There was a significant difference in tumor diameter between these two groups(P

Objective To compare the pharmacokinetics difference of methotrexate ( MTX) alone or MTX combined with the decoction of Radix Salviae Miltiorrhizae ( RSM) in rats, and to investigate the possible impact of RSM on the efficacy and pharmacokinetics of MTX after oral administration. Methods Sprague-Dawley rats were given MTX (7 mg/kg) alone or MTX together with RSM (3.085 g/kg) respectively. At different time points, blood was sampled from orbital venous plexus and then was precipitated by perchloric acid. The serum concentration of MTX was determined by using high performance liquid chromatography ( HPLC) method. Chromatographic separation was achieved on a reversed-phase Diamonsil C18 (2) column with the mobile phase of methanol-formic acid water solution (formic acid in volume fraction of 0.1%) in gradient elution. The column temperature was 27 ℃, flow rate was 1 mL/min, detection wavelength was 302 nm, and the injection volume was 10 μL. The results were analyzed by pharmacokinetic software DAS ( 2.1.1) by non-compartment model. Results The linearity of the calibration curve for MTX was good in the range of 0.097 6 ~ 12.5 mg/L, the detection limit was 0.097 6 mg/L and the recovery was in the range of 77.5% ~ 86.6%. Compared with MTX group, the peak-arriving time of MTX-RSM group was advanced, and the clearance of MTX was delayed. Area under concentration-time curve at 0-t (AUC(0-t)) was increased by 0.609 times, and AUC(0-∞) was increased by 0.786 times. Conclusion The decoction of RSM exerts an effect on promoting the absorption of MTX, delaying the clearance of MTX and enhancing the bioavailability of MTX in vivo.

Objective To investigate the diagnostic status of pulmonary thromboembolism (PTE) for inpatients in Peking Union hospital Methods Inpatients diagnosed acute PTE from January 1999 to December 2002 were reviewed and divided by sex, age and risk factors Results Among 78 844 inpatients, 155 were diagnosed PTE during 4 year period, 73 of 27 100 in men (0 27%) vs 82 of 51 744(0 16%)in women, and 52 of 17 459 (0 30% ) in elderly patients(≥60 years) vs 103 of 61 385 (0 17% ) in non elderly patients(

A recombinant plasmid pET28a-HBcAg-delta n was constructed, in which three mimic B-epitopes of HER family were inserted into the truncated HBc vector. The fusion protein expressed was purified and used to immunize BALB/c mice to induce antibody against the epitopes. Three mimic epitope genes were inserted into the sequences of amino acid residues 78 and 79 of HBcAg by overlap PCR. The PCR product was then cloned into pET28a to construct recombinant expression plasmid which was transformed to E. coli BL21 (DE3) and induced by IPTG. After purification, the fused protein designed HBHE was used to immunize BALB/c mice to detect humoral immunoresponse. The recombinant plasmid was successfully constructed by DNA sequencing analysis. A fusion protein with correct molecular mass was expressed and confirmed by SDS-PAGE. High titre antibody was elicited in the mice immunized with HBHE by indirect ELISA and Western blotting. The HBc particle vector containing three B-epitopes of HER family had been successfully prepared, purified and high titre antibody against HBHE was detected. All these data are helpful in further research of the broad-spectrum anti-tumour effect of combine polypeptide epi-position vaccine of EGFR and HER2.

Objective To investigate the effects of four interior-warming drugs( galangal,cinnamon,evodia rutaecarpa,and dried ginger)on the tension of ileum smooth muscle and Ca2+-ATPase on the cell membrane in rabbits. Methods The effects of galangal,cinnamon,evodia rutaecarpa,and dried ginger were examined on normal ileum smooth muscle,in vitro intestinal muscle contraction caused by acetylcholine(ACh),barium chloride(BaCl2 )and histamine(His), and ACh-induced calcium release by using BL-420E+ biological signal collection and processing system.The average tension was measured within 1 min before delivery and within 3 minutes after the treatment,and the inhibition rate was calculated according to the average tension value.The effects of sera containing galangal,cinnamon,evodia rutaecarpa,and dried ginger on Ca2+-ATPase activity on the cell membrane of the intestinal smooth muscle were examined by phosphorus method. Results Galangal,cinnamon,evodia rutaecarpa,and dried ginger at high concentrations could restrain in vitro intestinal contraction in normal circumstances(P<0.05 or P<0.01).Significant inhibitory effects on intestinal contraction caused by ACh,His and BaCl2 were found in low,medium and high concentration groups(P<0.01).There was a dose-effectiveness relationship between the inhibition rate and final drug concentrations.The ACh-induced intracellular and extracellular calcium dependent contraction were significantly inhibited by the four interior-warming drugs( P < 0. 05 or P < 0. 01). The Ca2+-ATPase activities were( 0. 384 ± 0.070),(0.302±0.016),(0.307±0.016),(0.296±0.016),(0.313±0.003)U·mg-1 ,respectively,in intestinal smooth muscle in normal control group and high concentration groups of galangal,cinnamon,evodia rutaecarpa,and dried ginger(P<0.01). Conclusion Interior-warming drugs may relax intestinal smooth muscle by reducing the intracellular calcium release and the extracellular calcium inflow via receptor-controlled calcium channels,and inhibiting the Ca2+-ATPase activity in smooth muscle.
