Objective To analyze the clinical efficacy and adverse reactions of desloratadine citrate decre-mental therapy in treatment of chronic urticaria.Methods 162 cases of patients with chronic urticaria were selected, they were randomly divided into observation group and control group.Control group was given routine treatment of desloratadine citrate capsule,while the observation group was given desloratadine citrate capsule decreasing therapy, the therapeutic effect and the levels of serum immunoglobulins were compared between the two groups.Results After treatment,the total effective rate of the observation group was 95.06%,there was no significant difference compared with 92.59% of the control group (χ2 =3.254,P >0.05);Two weeks and four weeks after treatment,IgE levels were significantly lower than before treatment,there were significant difference (t =8.291,7.931,6.936,5.152,all P <0.05),and the observation group change was more significant,the differences between the two groups were statistically significant (t =7.913,8.136,all P <0.05).After treatment symptom score was significantly lower than before treat-ment,and there were significant difference (t =7.519,8.015,all P <0.05),but the differences between groups were not significant (t =3.152,2.781,all P >0.05).The recurrence rate in the treatment group was 19.75%,which was significantly lower than the 40.74% of the control group,the difference between the two groups was statistically signif-icant (χ2 =6.914,P <0.05).But there was no significant difference in the incidence of adverse reactions between the two groups (χ2 =1.927,P >0.05).Conclusion Desloratadine citrate capsules in treatment of chronic urticaria can not only obtain more effective clinical curative effect,but also has less toxic side effect.For the purposes of the application method of the drug,decreasing method compared with conventional medication therapy can effectively improve the level of serum IgE.Therefore,it is worthy of clinical application.

Objective To investigate the effects of different ventilation modes on PaCO 2 and PaO 2 during laparoscopic surgery in the Trendelenburg position.Methods Forty cases of laparoscopic resection of rectal cancer were randomly divided into group A (n =20)and group B (n =20).Under general anesthesia,all the cases were in volume-controlled ventilation mode (VCV,tidal volume=10 ml/kg)before pneumoperitoneum.After ventilating in VCV mode for 20 minutes with a lower tidal volume (8 ml/kg),group A was converted to PCV mode for 20 minutes and then back to the VCV mode for 20 minutes again.Next we switched to PCV combined with PEEP (5 cm H 2 O)mode (PCV+PEEP)for 20 minutes.In group B,we only alternated PCV with PCV combined with PEEP.Arte-rial blood-gas analysis was obtained at each time when ventilating mode changed.Results In both group A and B,PaO 2 in VCV mode was less than that in PCV mode and PCV+PEEP mode (P <0.05),PaO 2 in PCV mode was also less than that in mode PCV+PEEP mode (P <0.05).PaCO 2 in PCV and PCV combined with PEEP mode was less than that in VCV mode (P <0.05 ),and there was no difference of PaCO 2 in PCV mode and PCV+PEEP mode.The pH value in VCV mode was less than that in PCV mode and PCV+PEEP mode (P < 0.05).There was no difference in pH value between PCV mode and PCV+PEEP mode.Conclusion PCV combined PEEP mode is beneficial ei-ther in increasing or decreasing of PaCO 2 during laparoscopic surgery in the Trendelenburg position comparing with single VCV mode or PCV mode.

Objective To investigate the effects of sulforaphane (SFN) on the proliferation of prostate cancer DU145 cells and hypoxia-inducible factor-1α(HIF-lα) expression,and to explore the possibility of SFN in the prevention of prostate cancers.Methods The DU145 cells were treated with different doses and different time of SFN.The cell proliferation viability were measured by 3-(4,5)-dimethylthiahiazo (-zy1)-3,3,5-di-phenytetrazo`liumromide (MTT) proliferation and cytotoxicity assay kit.The hypoxia tumor microenvironment was stimulated by pretreating cells with 1％ O2,HIF-lα expression and vascular endothelial growth factor (VEGF) activitity were detected by Western-blot and ELISA,respectively.Results SFN had an inhibitory effect on the proliferation of human prostate cancer DU145 cells in a dose-and time-dependent manner.The cell proliferation inhibition rate exceeded 50％ in more than 20 μ mol/L SFN-treated groups after 48 hours.SFN could inhibit the expression of HIF-1α induced by 1％ O2 and VEGF activity.10 μmol/L SFN showed inhibitory effect on the expression of HIF-1α after 24 hours.20 μ mol/L SFN showed a significant inhibitory effect on the expression of HIF-1α after 12 hours.And peroxidase had synergistic inhibition on HIF-1α.Conclusions SFN can inhibit the proliferation of DU145 prostate cancer cells and HIF-lα expression.SFN can be used as a potential chemotherapeutic agent against human prostate cancer.

BACKGROUND:Precision attachment has been widely used in complete denture because of its strong retention, good appearance, comfort and durability. Among them, magnetic attachment and bal-cap attachment are commonly applied for mandibular complete denture.
OBJECTIVE:To compare the clinical effects of magnetic attachment, bal-cap attachment and traditional clasp retainer used in the mandibular removable partial denture.
METHODS:A total of 45 patients with dentition defects were included in this study, they were treated with magnetic attachment, bal-cap attachment and traditional clasp retention of mandibular removable partial denture. Fifteen patients received one means. The satisfaction of patients and the periodontal health of abutments were observed after 3 years.
RESULTS AND CONCLUSION:Comparison of the patient satisfaction showed that, the aesthetics, retention conditions, masticatory function and comfort in magnetic attachment group were significantly better than traditional clasp retention group (P<0.05). The aesthetics and comfort in bal-cap attachment group were also better than traditional clasp retention group (P<0.05). There were significant differences on the retention conditions and comfort between magnetic attachment group and bal-cap attachment group (P<0.05). Gingival index was the highest in magnetic attachment group, then in bal-cap attachment group, and the lowest in traditional clasp retention group (P<0.05). The abutment tooth mobility degree was the lowest in magnetic attachment group, then in bal-cap attachment group, and the highest in traditional clasp retention group (P<0.05). The periodontal pocket depth in magnetic attachment group and bal-cap attachment group was lower than that in traditional clasp retention group (P<0.05). The alveolar bone height was the highest in magnetic attachment group, then in bal-cap attachment group, and the lowest in traditional clasp retention group (P<0.05). Experimental findings indicate that, precision attachment over-denture retention superior to traditional clasp removable partial denture in mandibular denture repairing. Magnetic attachment can provide better retention power and better protect the health of periodontal tissue compared with bal-cap attachment.

Objective To investigate the diagnostic value of tumor marker measurement in biliary juice obtained during endoscopic retrograde cholangiopancreatography (ERCP) in differential diagnosis of suspected biliary-pancrentic diseases.Methods ERCP was performed in patients with suspected biliarypancreatic lesions that could not be diagnosed by routine methods including ultrasonography,MRCP,blood biochemistry and serum tumor marker test,and biliary juice was obtained to measure tumor markers including CEA and CA199.A total of 29 patients with definitive diagnosis were recruited and divided into benign and malignant groups.Serum biochemical findings and tumor markers were compared between 2 groups.The diagnostic value of uhrasonography,EUS,MRCP,ERCP and ERCP combined with biliary tumor markers were also compared.Results There was no significant difference in serum biochemical findings,serum CEA,serum CA19-9 or biliary CA19-9 between 2 groups,while the average biliary CEA in malignant group was significandy higher than that in benign group (P＜0.001).The accuracy of ERCP combined with biliary tumor markers in diagnosing suspected biliary-pancreatic diseases was 69.0%,which was higher than that of ultrasonography (6.9%),MRCP (37.9%) and ERCP (41.4%),respectively.Conclusion The diagnostic accuracy of suspected biliary-pancreatic diseases can be improved through ERCP combined with biliary CEA test,which is helpful in differential diagnosis between benign and malignant lesions.

The number of projects from free applications of the national natural science foundation of China (NSFC) about pharmacology of antitumor drugs in 2001 increased evidently than before. Those projects were mainly about the exploration of the natural materials with antitumor activity, investigation in new targets of antitumor drugs, study in the inhibition of angiogenesis in tumor cells,etc. The tumor pharmacology in China has made some progress, but it still lags much behind the international study level. Basic work and creative ideas should be strengthened for further development.
