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.

ObjectiveTo investigate the expression of midkine(MK) and its relation with angiogenesis, biological features and prognosis of pancreatic carcinoma(PC).MethodsMK expression and microvessel density(MVD) were determined in 52 cases of human PC with immunohistochemistry and results were compared with pathology.ResultsMean MVD of PC was 64?18 and positive expression of MK was detected in 38 cases (73%). The positive rate of MK was significantly lower in cases of without metastasis and at early clinical stage (stageⅠ～Ⅱ) than that with metastasis and at stage Ⅲ～Ⅳ. MVD was significantly higher in MK-positive PC than in MK-negative PC (P

Objective To determine the effect of enflurance on nitric oxide synthase (NOS) activity and nitric oxide (NO) content in different brain regions at different anesthesia stages.Methods Forty female SD rats weighing 250-350 g were randomly divided into five groups of 8 animals each, group 1: control; group 2: induction of anesthesia; group 3: maintenance of anesthesia; group 4: recovery from anesthesia and group 5: complete recovery. Animals were placed in a special glass anesthesia box. The concentration of enflurane in the box was measured by anesthesia gas monitor (Normac). The induction of anesthesia started from staggering of the animal to loss of righting reflex, maintenance of anesthesia from 1 min after loss of righting reflex, recovery of anesthesia from recovery of righting reflex to staggering after enflurance anesthesia was discontinued and glass box was opend and complete recovery from 1h after recovery of righting reflex. The animals were decapitated at different stages of anesthesia. Cerebral cortex, hippocampus and brain stem were immediately removed on ice and frozen in liquid nitrogen. Their NOS activity and NO content were measured by spectroscopic analysis. Results The average duration from the beginning of 2.2% enflurane inhalation to loss of righting reflex was (169?30) s. The average duration of anesthesia induction was (138?36)s. The maintenance of anesthesia lasted (229?30) s and the recovery period averaged (266?41) s. The NOS activity and NO content in different brain regions began to decrease during induction of anesthesia and reached their lowest level during maintenance of anesthesia, began to increase during recovery from anesthesia and returned to preanesthetic level during complete recovery. Conclusion Enflurane significantly inhibits the NOS activity and NO content in the brain. The inhibits is closely related to the depth of anesthesia. NO is a message transmitter in central nervous system and may be involved in the mechanism of enflurane anesthesia.

Objective To investigate the effect of thiopental sodium (TPS) on spontaneous and KCl-evoked glutamate release from prefrontal cortical synaptosomes in rats and the effect of bicuculline on this effect ofTPS.Methods SD rats of both sexes (200-250 g) were decapitated and brains were removed. The prefrontalcortex was dissected and added to ice-cold sucrose solution and homogenized. The homogenate was centrifuged at1000 g at 0℃-4℃ for 5 min. The supernatant was again centrifuged at 12 000 g for 20 min. The sediment wascrude synaptosomes, which was added to artificial cerebro-spinal fluid (ACSF). The crude synaptosomes weredivided into 5 groups (n = 8): control group and 4 TPS groups. In control group no TPS was added while in TPSgroups different concentrations of TPS was added and the final concentration of TPS was 10, 30, 100, 300?mol?L~(-1) respectively. The synaptosomes were then placed with or without KCl in water bath at 37℃ for 15 min. Thespontaneous or KCl-evoked glutamate release was measured using high-performance liquid chromatograph (HPLC).In another set of experiment bicuculline 0. 1 mmol?L~(-1) was added to ACSF in each group before 15 min water bathto see if it could antogonize the effect of TPS on glutamate release. Results TPS 30, 100 and 300 ?mol?L~(-1)could significantly inhibit the spontaneous or KCl-evoked glutamate release compared with control group (P0.05). Bicuculline 0. 1 mmol?L~(-1) had no effect on the glutamate release in control group but could antagonize the inhibitory effect of TPS on glutamate release. Afteraddition of bicucculline the glutamate released in control group was not significantly different from that in the TPSgroups.Conclusion TPS sodium can inhibit the spontaneous or KCl-evoked glutamate release from prefrontalcortical synaptosomes in a concentration-dependent manner. The inhibitory effect is mediated by GABA_A receptors.

Objective To investigate the effect of Xuebijing injectiong on lipopolysaccharide(LPS)-induced apoptosis of CD4+CD25+regulatory T cells(Tregs)and immune function of effector T cells(Teff)in vitro.Method CD4+CD25+Tregs isolated from rat spleens were divided into the control group,anti-CD3/CD28 group,anti-CD3/CD28+LPS group,anti-CD3/CD28+Xuebijing injection group,and anti-CD3/CD28+LPS+Xuebijing injection group.The apoptosis rate and expression of forkhead/winged helix transcription factor p3 (Foxp3)and cytotoxic T-lymphocyte-associated antigen 4(CTLA-4)of CD4+CD25+Tregs were detected by flow cytometry(FCM),and the secretion of IL-10 of Tregs was measured by ELBA on day 3.CD4+CD25-T cells were co-cultured with CD4+CD25+Tregs(1:1)for 68 hours,proliferative activity of Teff was determined by MTT,and interleukin(IL)-2/sIL-2Rα levels were measured by ELISA.Results The apoptosis rate of CD4+CD25+Tregs in anti-CD3/CD28 group was 33.70± 3.06%,which was significantly higher than that in control group(12.84±0.84%).Also,apoptosis rate of CD4 CD25+Tregs in anti-CD3/CD28+LPS+Xuebijing injection group(45.13±2.70%)was much higher than that in anti-CD3/CD28+IPS group(29.41 ± 1.63%,P＜0.01).The expression of Foxp3 as well as CTLA-4,and the secretion of IL-10 were markedly decreased along with increases in the apoptosis rates.Compared with control group(54.48%),the mean inhibitory rate of Teff proliferative activity in response to Con A was significantly decreased in anti-CD3/CD28+Xuebijing injection group(31.26%,P＜0.05),and it was markedly decreased in anti-CD3/CD28+LPS+Xuebijing injection group comaped to anti-CD3/CD28+LPS group(P＜0.01).In addition,IL-2 levels in the supernatant of anti-CD3/CD28+Xuebijing injection group and anti-CD3/CD28+LPS+Xuebijing injection group were significantly higher than those of anti-CD3/CD28+IPS group(P＜0.01).Conclusions The inhibitory activity of CD4+CD25+Tregs on Teff appears to be upregulated by IPS stimulation in vitro,and Xuebijing injection could markedly enhance apoptosis of CD4+CD25+Tregs,thereby improving suppressive immune function of Teff.
