Objective To evaluate the effects of rabeprazole-based triple therapy for associated gastric ulcer caused by the helicobacter pylori(Hp) infection. Methods 100 patients with associated gastric ulcer caused by the Hp infection were randomly divided into treatment group and control group. The treatment group was given rabeprazole-based triple therapy( rabeprazole 10mg bid, amoxicillin 1.0g bid and clarithromycin 500mg bid), and the control group was given omeprazole-based triple therapy( omeprazole 20mg bid, amoxicillin 1.0g bid and clarithromycin 500mg bid). The two groups were given 7 days treatment. Results The total effective rate of clinical symptoms of treatment group was 96. 0% ,the healing rate of the treatment group was 88.0%, the total effective rate of gastroscopy effect of treatment group was 94.0% ,the Hp clearance rate of treatment group was 92.0% and the Hp eradication rate of treatment group was 90. 0% ,which were higher than the control group,but the difference was not significant( P ＞ 0. 05 ). The two groups had no significant adverse reactions. Conclusion Rabeprazole-based triple therapy for associated gastric ulcer caused by the Hp infection was effective, safe and worth popularization and application.

Gout is a metabolic inflammatory disease characterized by hyperuricemia. When serum uric acid concentration(sUA) is greater than 420 μmol/L, monosodium urate(MSU) crystals are formed and deposited in joints and connective tissues, resulting in acute gout arthritis. In addition to the concentration of urate, pH is also one of the factors affecting MSU deposition. Lowering pH can promote MSU crystallization. Urine alkalization can raise the pH to 6.2~6.9, which can increase the solubility of urate to prevent MSU deposition and the formation of uric acid stones. Commonly used clinical medications include citrate, bicarbonate, acetazolamide, tromethamine, etc. Among them, potassium citrate is the most commonly used alkali agent in clinical practice. However, due to adverse drug reactions, clinical medications need to be cautious. In addition to pharmacotherapy, dietary intervention has also become an important means of alkalizing urine. When sufficient attention is paid to the construction of a balanced diet, dietary intervention will become a safe and economical method for the treatment of gout, but the long-term efficacy has not been determined. This article discusses the advantages and disadvantages of urine alkalinization in the application of hyperuricemia and gout from aspects of pharmacological treatment and diet management, and provides a basis for proper medication use.

Objective To observe the specific humoral and cellular immune response in BALB/c mice injected with pS and p18S. Methods pS and p18S were constructed separately by inserting HBsAg gene fragment and the fusion gene fragment of HBsAg and mouse interleukin 18(IL 18) into the reading frame of pcDNA3.1+. Mice were injected with either plasmid intramuscularly in a total dose of 300 ?g per mouse. Every serum sample was detected for anti HBs using enzyme linked immunosorbent assay(ELISA). Furthermore, HBsAg specific cytotoxic T lymphocytes activity was measured. Results The expression of HBsAg was demonstrated by ELISA in p815 cells transfected with pS and p18S. pS can stimulate a positive antibody response. The average level was 135 mIU/ml, with the highest level of 530 mIU/ml. p18S could elicit relatively lower antibody response which was 20 mIU/ml. HBsAg specific CTL activities were 37.1% and 34% separately in pS and p18S immunized mice. It was only 13.2% when detected in pcDNA3.1+ immunization. Conclusion pS is effective to stimulate a humoral and cellular response in H 2d mice. IL 18 gene can not enhance the immune response when fused with HBsAg gene. Conversely, it seems to inhibit an immune response.

Objective To study the receptors for the axon guidance factor Netrin-4 and whether the known Netrin-1 receptors, DCC and UNC5H1, are coreceptors for Netrin-4. Methods The receptor for Netrin-4 was detected by affinitycytochemistry and in situ staining with the alkaline phosphatase (AP) tagged Netrin-4 fusion protein. The dynamic character of the binding between Netrin-4 and its receptor was evaluated through ligand-receptor binding assay and competitive binding assay. Results In situ staining of AP4-Netrin-4 protein bound to COS7 cells transiently transfected with eukaryotic expression coding DCC and UNC5H1 showed that the Netrin-4 could bind to the transfected cells. Competitive binding assays showed that Netrin-1 could compete with Netrin-4 for the same receptors. Conclusion DCC and UNC5H1 are coreceptors for Netrin-4. However, because the binding affinity of Netrin-4 with its receptor was lower than that of Netrin-1,it could be inferred that there should exist unique receptor(s) for Netrin-4 other than DCC and UNC5H1.

Immobilized penicillin acylase was used for bioconversion of penicillin G into 6-APA in aqueous two-phase systems consisted of a light-sensitive polymer PNBC and a pH-sensitive polymer PADB.Partition coefficients of 6-APA was found to be:about 5.78,in the presence of 1% NaCl.Enzyme kinetic showed that reaction reached equilibrium at 7h or so.The 6-APA mole yields were 85.3%(pH 7.8,and 20 ℃) and this value was about 20%higher than control in reaction of single aqueous phase buffer.Partition coefficient of penicillin G(Na) washardly changeable,while partition coefficient of product,6-APA and phenylacetate acid was significantly changeable.Reason is due to Donnan effect of phase systems andhydrophobicity of products.The change of partition coefficients of products also affects bioconversion yield of products.In the aqueous two-phase systems,substrate,penicillin G,products 6-APA and phenylacetate acid are biased in top phase,while immobilized penicillin acylase is completely partitioned in bottom.Substrate,penicillin G enters into bottom phase,and it is catalyzed into 6-APA and phenylacetate acid,then the products enter into top phase.Finally,inhibition of substrate and products is removed to result in improvement of products yield.Moreover,immobilized enzymehashigher efficiency than immobilized cells and occupy smaller volume.Comparing with free enzyme,immobilized enzymehashigher stability,longer use life,completely partitioned in bottom phase and recycle.Bioconversion in two-phase systems using immobilized penicillin acylase showed outstanding advantage.The light-sensitive copolymer forming aqueous two-phase systems could be recovered by laser radiation at 488 nm or filtrated 450 nm light,while pH-sensitive polymer PADB could be recovered by isoelectric point(pH 4.1).The recovery of the two copolymers was 95%~99%.

Objective To evaluate the effectiveness of arthroscope-assisted surgical technique in treating knee fractures and knee peripheral fractures.Methods From September 2000 to December 2005,there were 46 cases with knee or knee peripheral fractures,in whom artbroseope-assisted surgical technique was performed in 36 cases including 24 males and 12 females,with mean age of 30.5 years (18-52 years).Of 36 cases,26 cases with patella fractures were treated by internal fixation of tension band using cancellous bone screws,four with distal end femoral fractures by retrograde interlocking using intramedullary nail and six with fractures of tibial plateau and tibial condyle crista by internal fixation u- sing cancellous bone screws.Results The mean hospitalization was eight days.A follow up for 3-36 months(average 14 months)in 36 cases showed fracture healing.Of 36 cases,32 cases regained full knee range of motion,four left with terminal flexion,with mean loss of 15?,and had thigh circumference (10 cm above knee)1.1 cm(range 0.6-2.0 cm)shorter than health side and two had slight pain in the knee joint.Lysholm knee joint function score was 86.5+7.6 for patellar fractures,tibial plateau frac- tures and condylar crista fractures.Conclusion As for knee or knee peripheral fractures,arthroscope- assisted surgical technique can provide fine monitoring,decrease trauma and complications,fixate inter- nally and help early ground exercise.

AIM:To investigate the role of potassium channel expression alteration in chronic cigarette smoking-induced increase in pulmonary vascular responsiveness,the effect of chronic cigarette smoking on large-conductance calcium-activated potassium channel(BKCa) and voltage-dependent delayed rectifier potassium channel(Kv1.5) expression in rat pulmonary smooth muscle cells were investigated in vivo.METHODS: HE staining,immuno-histochemistry and in situ hybridization techniques were used.RESULTS:(1) Chronic cigarette smoking downregulates the protein and mRNA expression of BKCa in pulmonary arterial smooth muscles.(2) Chronic cigarette smoking downregulated the protein and mRNA expression of Kv1.5 in pulmonary arterial smooth muscles.(3) In big artery,BKCa decreased more makedly than Kv1.5,but in small artery,both of them decreased equally.CONCLUSION: Chronic cigarette smoking downregulates the levels of BKCa and Kv1.5 in rat pulmonary arterial smooth muscle cells in vivo,which maybe contribute to the mechanism of cigarette smoking-induced increase in pulmonary vascular responsiveness.

mRNAs of alpha-adrenoceptor (α-AR) subtypes are found in neurons in dorsal root ganglion (DRG) and change after peripheral nerve injury. In this study, the distribution of α-AR subtype proteins was studied in L5 DRG of normal rats and rats with chronic constriction injury of sciatic nerve (CCI). Using immunofluorescence technique, it was found that α1A-, α1B-, and α2A-AR proteins were expressed in large, medium, and small size neurons in normal DRG, and significantly increased in all size neurons 14 days after CCI. α1D- and α2C-AR was also expressed in all size neurons in normal DRG. However, α1D-AR was significantly increased and α2C-AR was decreased in small size neurons 14 days post CCI. α2B-AR neurons were not detectable in normal and CCI DRG. Co-expression of α1A- and α2A-AR in the same neuron was observed in normal DRG and increased post CCI. Collectively, these results indicated that there is distinct distribution of α-AR subtypes in DRG neurons, and the distribution and levels of expression of α-AR subtypes change differently after CCI. The up-regulation of α-AR subtypes in DRG neurons may play an important role in the process of generating and transmitting neuropathic pain.

Objective To explore the effect of cutaneous never anastomosis on sensory recovery in repairing wide spreadly soft tissue defects in dorsal hand with free anterolateral femoral flap. Methods The cases with wide spreadly soft tissue defects in dorsal hand repaired with free anterolateral femoral flap from January 2006 to December 2012 were divided into 2 groups. The control group including 15 consecutive patients from January 2006 to January 2009, whose sensation was reconstructed in routine way. Other 15 consecutive patients from Febnary 2009 to December 2012 were as research group, whose sensation was reconstructed with the suture of cutaneous nevers of anterolateral femoral flaps and forearm. All the patients were followed up for 12~24 months. Results All the free flaps survived in both groups. There were 4 cases good of sensory recovery in the control group, and it was 11 in the research group. No ulceration happened. Conclusion Cutaneous never anastomosis may result in satisfactory sensory function in the patients with wide spreadly soft tissue descts in dorsal hand repaired with free anterolateral femoral flap.
