Objective To evaluate the therapeutic effect of tulobuterol tape on mild or moderate bronchial asthma in children less than three years old . Methods Sixty-two children with mild or moderate asthma were randomized to receive either tulobuterol tape(treatment group) or procaterol hydrochloride tablet(control group) on the basis of inhaled fluticasone propionate for 2 weeks. Symptom scores of asthma, frequencies of episode of wheeze, doses of inhaled ventolin as rescue drug and the incidence of adverse reactions were recorded. Results In the treatment group,the symptom scores during daytime in the treatment group were (2. 2 ±0. 9)/week and (0. 9 ±0. 5)/week after 1 and 2 weeks of treatment, respectively, which were significantly lower than that in the control group(3.4 ± 1. 1)/week and (1. 3 ± 0. 6)/week after 1 and 2 weeks of treatment, respectively) (P < 0. 05). The symptom scores during night in the treatment group was significantly lower than that in the control group after one week of treatment (1. 8 ± 0. 7) /week v. s. (3. 3 ± 0. 9) /week, P < 0. 05). The frequencies of episode of wheeze was significantly different between the two groups (2. 3 ±1.2 and 3. 6 ± 1.3 in the treatment and control groups, respectively (P < 0.05) .The doses of inhaled ventolin in the treatment group (2. 6 ±0.9 spray/week) was significantly lower than that in the control group (3.7 ± 0. 8) spray/week) (P < 0. 05). The incidence of adverse reactions in the treatment group was significantly lower than that in the control group (3. 12% v. s. 23. 33% ,x2 = 3. 89,P<0.05). Conclusions Tulobuterol tape is a safe and effective medication for the treatment of mild or moderate bronchial asthma in children less than three years old.

Objective To discuss the effects of peritoneal dialysate (PDS) on the expression of aquaporin-1 in rat peritoneal mesothelial cells (RPMCs). Methods The in vitro cultured RPMCs were divided randomly into 4 groups, and stimulated respectively with 1640 culture medium containing 10% fetal calf serum (negative control), and three kinds of PDS (containing respectively 4.25% glucose, 4.25% mannitol or 1.5% glucose) for 3 hours. Indirect immunofluorescence assay (IFA) and flow cytometry (FCM)were employed to detect the expression of aquaporin-1 in RPMCs stimulated by different kind of PDS as above. Results Compared with negative control and the group with PDS containing 1.5% glucose, the expression of aquaporin-1 on the mesothelial cells of the group with PDS containing 4.25% glucose and that containing 4.25% mannitol was significantly up-regulated (P0.05). Conclusion PDS with higher osmotic pressure (OP) can enhance the expression of aquaporin-1 in RPMCs. For PDS with same OP (PDS containing 4.25% glucose or PDS containing 4.25% mannitol), those containing glucose can enhance the expression of aquaporin-1 more effectively than that PDS containing mannitol. This result indicates that glucose or its degradation products may be the independent factors in enhancing the expression of aquaporin-1 of RPMCs.

Objective To investigate the clinical application prospect of water exchange colonoscopy.Methods A total of 300 outpatients who underwent unsedated colonoscopy were randomized to the WEC group (n =150)or the AIC group(n =150).The maximum pain score, insertion time, the cecal intubation rate and the polyp detection rate were reported by an assistant during the insertion phase and at the end of colonoscopy.Results The maximum abdominal pain scores were 1.77 ± 1.29 in the WEC group and 2.84 ± 1.55 in the AIC group with significant difference (P =0.000).The intubation time of WEC was longer than that of AIC (11.91 ± 3.58 VS 8.03 ± 3.19 ,P =0.000)with no significant difference.There was no significant difference in the cecal access rate between the two groups(97.3％ VS 94.0％ ,P =0.157).The polyp detection of WEC was higher than that of AIC (16.7％ VS 10.0％, P =0.089).In the post abdominal operation subject of colonoscopy procedure, WEC had higher rate of cecal intubation than AIC ,the maximum abdominal pain score were 2.25 ± 1.63 in the WEC group,lower than 3.48 ± 1.45 in the AIC group.Conclusion Water exchange colonoscopy can alleviate patients' abdominal pain symptoms, but with longer insertion time.There are no significant difference in the cecal access rate and the polyp detection rate between two groups.For difficult colonoscopy, water exchange colonoscopy is helpful to increase the rate of cecal intubation.

It was found that after 2 dosages of Pseudomonas aeruginosa suspension(7?109/kg and 2?1010/kg)were infused to rabbits respectively to induce septicemia,the elevation of the tumor necrosis factor(TNF)level in the circulating blood was higher in 2?1010/kg group than in 7?109/kg group.The dynamic changes of circulation TNF in P.aeruginosa septicemia were different from those in endotoxin shock.There was a continous increase of plasma glucagon,Iactic acid and ?-G(P

After intravenous infusion of recombinant human tumor necrosis factor(TNF)in the dosage of 60?g/kg or 130?g/kg to rabbits,it was found that their plasma malondialde-hyde(MDA)was significantly increased(P

Objective To design siRNA for Caveolin-1(CAV1) and construct eukaryotic expression vector Dsilence4.1-CMV-neo-CAV1, which is transfected into gastric cancer cell line SGC7901 to study the effects of inhibition of CAV1 expression with siRNA on biological behavior of gastric cell line SGC7901.Methods Design and chemosynthesize three pairs of double strands siRNA based on the neucleotide sequence of CAV1 gene provided by GeneBank.The siRNAs were transient transfected into SGC7901.The CAV1 expression of transfected cells were detected respectively by semi-quantity RT-PCR to sieve a valid siRNA sequence.Design and synthesized DNA sequence which can express small hairpin RNA(shRNA),construct RNA interfering eukaryotic expression vector of CAV1 gene.The SGC7901 Was stably transfected and was detected the expression of CAV1 gene by RT-PCR.The influence on the gastric cell growth and pmliferation after CAV1 was inhibited Was detected by cell growth curve, clone formation test and FCM.Results The CAV1 RNA interfering eukaryotic expression vector psilence4.1-CMV-neo-CAV1 was successfully constructed,which can significantly reduce the expression of CAV1 after stably transfected to target cells,and in contrast to Dsilence4.1-CMV-neo transfection group,PI and colony for mution rate were increased(t=7.98,P<0.05;t=13.19,P<0.01),the growth speed Was up.Conclusion The growth and proliferation ability of tumor is remarkablv accelerated by inhibiting the expression of CAV1 of gastric cell by RNAi.

Pegylated interferon (PEG-IFN) combined with ribavirin (PR regimen) has been used in China for more than 10 years.With the development of direct-acting antiviral agents (DAAs),the therapeutic regimens for hepatitis C has become more and more diverse.In the regimen of DAAs combined with PR regimen,IFN helps to benefit the long-term prognosis of patients with chronic hepatitis C (CHC),and the addition of DAAs may improve therapeutic effect,shorten the course of treatment,and further improve the current status of treatment of CHC.This article introduces the advantages and disadvantages of PR regimen,DAAs combined with PR regimen,and oral regimen with DAAs,in order to investigate the therapeutic regimens suitable for different CHC patients and provide a reference for clinical practice.

Objective To determine the genetic diversity of germplasm resource in cultivated and wild Cistanche deserticola. Methods Fifty-eight samples from three populations of cultivated and wild C. deserticola were analyzed by amplified fragment length polymorphism (AFLP) DNA markers, and the gene- tic diversity was evaluated by PopGen32. Results The average percentage of polymorphic loci (PPL) of cultivated C. deserticola is 79.16%. The PPL of wild population is 89.53%. Average Neis gene diversity index (He) from four populations was 0.193 8, Shannons genetic diversity index (I) was 0.300 4, and genetic differentiation index (Gst) was 0.097 9. Conclusion The diversities of cultivated and wild C. deserticola are both higher and theres no differentiation between them. It shows that genetic diversity of inner-species is higher, which is not the reason for endangerment. Therefore, wild nursery and artificial cultivating are the best measures for the conservation and sustainable utilization in C.deserticola.
