OBJECTIVE:To investigate situation and trend of proton pump inhibitors in 19 hospital of Hangzhou area and to provide reference for the research,production,sales and clinical application of this kind of drugs. METHODS:Utilization of proton pump inhibitors in 19 hospital of Hangzhou area during the period of 2004～2008 were analyzed statistically in respect of consumption sum,DDDs and DDC. RESULTS:Both consumption sum and DDDs of proton pump inhibitors increased quickly in recent five years. Amount of oral omeprazole(capsule and tablet)was the greatest among those categories and increased steadily. Amount of rabeprazole and esomeprazole as new type of proton pump inhibitors increased rapidly. CONCLUSION:Proton pump inhibitors have great potential for development. Omeprazole are widely used in the clinic as mature proton pump inhibitors.

OBJECTIVE: To develop a method for determination of the content of Dexamethasone acetate in Compound tretinoin ointment by RP-HPLC. METHODS: The separation was performed on C18 column with methanol: water (70∶30) as a mobile phase, wavelength of UV detector at 240nm. RESULTS: The linear range of Dexamethasone acetate was within 0.028 3～0.849 0?g(r=0.999 9). The average recovery of Dexamethasone acetate was 101.13%, with RSD at 1.28%. CONCLUSION: The method is simple, rapid and capable of producing good separation results. It can be applied to the quality control of Compound tretinoin ointment.

Objective To explore the clinical significance of gastric hyperplastic polyp pits under magnifying endoscopy. Methods Summary confirmed by magnifying endoscopy and pathological examination gastric hyperplastic po]yp's performance of magnifying endoscopy,Hp positive and the results of pathology during February 2004 to De-cember 2006. Results 55 patients found 116 gastric polyp,41.4% (48/116) with type A,26.7% (31/116) with type B,19. 8% (23/116) with type C,8. 6% (10/116) with type D,2. 6% (3/116) with type E,one case gastric pits blurred(type F) 0. 9% (1/116). 4 cases with type E and type F found moderate-severe atypical hyperplasia. Conclu-sion Gastric hyperplastic polyp pits with type E and type F ,their results of pathology to display atypical hyperplasia.

Objective To investigate and improve the methods of nasal feeding to reduce the occurrence of complication such as diarrhea and vomiting.Methods We separated 140 patients with heavy craniocerebral injury into the control group (50 patients) and the experimental group (90 patients) according to different nasal feeding methods. For the control group traditional method was used. For the experimental group infusion pump was used to control infusion rate. The incidence of complication was compared between two groups. And within experimental group, the same nutrient solutions in respect of type and volume were infused during 10 hours, 16 hours, and 18 hours respectively. The relationship between infusion rate and the occurrence of complication was observed, analyzed and compared to seek for the most suitable enteral nutrition route which incurred the least complication.Results The incidence of diarrhea and vomiting in the experimental group was lower than that of the control group. And there were no significant differences in the occurrence of complication by using infusion pump at three different infusion rates within the experimental group. Conclusions The application of infusion pump in nasal feeding can reduce the incidence of complication and infusing nutrient solution at a slow rate was not necessary.

Objective To study serum lipid levels in Uygur and Han nationalities in Urumqi of xinjiang, and their related risk actors. Methods Form 2004 to2007, 4 329 subjects were gathered from Urumqi Uygur and Han nationalities, all participants had a physical examination and serum lipid glucose test. Results The level of cholesterol and high density lipoprotein-cholesterol in Han nationality were significantly higher than Uygur. The levels of triglyceride, low density lipoprotein -cholesterol in Uygur were significantly higher than Han nationality. Hyperlipidemia in Uygur and Han nationality was affected by age (OR=1.377, 95%CI 1.144~ 1.659), body mass index (OR 1.56, 95%CI 1.386~1.756), and fasting glucose OR=1.386, 95%CI 1.15~1.67). Conclusion There were significant differences between Uygur and Han in the levels of serum lipids. Age, BMI and Fasting glucose also affected the serum lipid metabolism.

Objective To observe the connections between enkephalin immunoreactive(ENK-ir) terminals and ?-aminobutyric acid immunoreactive(GABA-ir) neurons in the rostral portion of the nucleus tractus solitarious(rNTS) of the rat. Methods Double-immunofluorescent labeling method and the pre-embedding immunohistochemical staining combined with immuno-gold particles labeling technique for electron microscopic detection were used in the present study. Results Under the laser scanning confocal microscope,dense ENK-ir fibers and terminals and some GABA-ir neurons were observed in the rNTS.Close contacts between ENK-ir terminals and GABA-ir cell bodies were also detected.By using the electron microscopic technique,ENK-ir reaction products were found to be mainly localized on the surface of round clear vesicles and dense-cored vesicles in the axon terminals.ENK-ir terminals formed symmetric,which was a dominant pattern,and asymmetric synaptic connections with GABA-ir and immunonegative cell bodies and dendrites.Conclusion The ENK-ir terminals might take part in the transmission and regulation of the taste information in the rNTS through inhibiting,exciting the GABAergic neurons or inhibiting directly the activity of neurons within the rNTS.

Objective To explore the influence of recombinant human erythropoietin(rhEPO) injection about nitric oxide(NO) and nitric oxide synthase(NOS) level in the brain and endothelin(ET) level in the blood after hypoxia-ischemia brain damage(HIBD) in neonatal rats,and elucidate the possible mechanism of the neuroprotective effect of rhEPO administered to the rat pup prior to cerebral hypoxia-ischemia.Methods Seven days-old SD rats were divided into control group,hypoxia-ischemia group(HI) and EPO group.NO activity,NOS level in the brain and ET in the blood were determined at 6 h after hypoxia-ischemia.Results NO and NOS levels in the brain and ET level in the blood were increased after HIBD in neonatal rats(P
