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.

BACKGROUND:There are few reports about the effect of serum-free culture on the differentiation of rat adipose-derived stem cel s into vascular endothelial cel s.
OBJECTIVE:To investigate the isolation, serum-free culture of rat adipose-derived stem cel s differentiating into vascular endothelial cel s.
METHODS:The rat adipose-derived stem cel s were isolated from male Sprague-Dawley rats and expanded to the third passage by enzymatic digestion-adherent explants method. In the experimental group, rat adipose-derived stem cel s were cultured in serum-free medium for 24 hours. In the control group, rat adipose-derived stem cel s were cultured in low-glucose Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum. After that, the cel s were cultured in inducing medium for 3 weeks to differentiate into vascular endothelial cel s.
RESULTS AND CONCLUSION:The rat adipose-derived stem cel s grew as polygonal or fusiform-shaped adherent cel s when cultured in vitro, which could stably proliferate and passage. The rat adipose-derived stem cel s showed very low expression of CD31, a cel surface marker, after passages. After directional differentiations into vascular endothelial cel s, the cel s were pebble-shaped under the inverted microscope. Expression of CD31 was up-regulated, which was much higher in the experimental group than the control group. The induced cel s in the experimental group had stronger abilities than those in the control group to swal ow Dil-labeled acetylated low-density lipoprotein and form tube-like structures on the matrigel after differentiation into vascular endothelial cel s. So, rat adipose-derived stem cel s could be highly successful y induced to differentiate into vascular endothelial cel s in vitro after serum-free culture.

BACKGROUND:Titanium zirconium niobium tin al oy (Ti-Zr-NB-Sn al oy) has good tissue structure, mechanical properties, corrosion resistance and biocompatibility, which is an ideal dental material. OBJECTIVE:To explore the efficacy and safety of Ti-Zr-NB-Sn al oy in dental restoration. METHODS:A retrospective analysis was performed on clinical data of 87 cases of dental defects, including 43 males and 44 females, aged 22-41 years. Of the 87 cases, 43 cases were repaired with Ti-Zr-NB-Sn al oy as observation group, and the other 44 cases were treated with nichrome as control group. After 36 months of fol ow-up, the therapeutic efficacy, dental restoration conditions, dental prosthesis conditions and patient satisfaction were observed and compared. RESULTS AND CONCLUSION:Al the 87 patients were fol owed up for 36 months. After the fol ow-up, the total effective rate and patient satisfaction were higher in the observation group than the control group (P<0.05). In the control group, there were four cases of swol en gums, four cases of bleeding gums, four cases of al ergies, three cases of gum gray line, and six cases of mucosal pain;in the observation group, there was only one case of swol en gums, and the dental restoration was better in the observation group than the control group (P<0.05). For the dental prosthesis, there were 10 cases of dental stent damage and 20 cases of dental stent loosening in the control group;and only one case of dental stent damage and one case of dental stent loosening in the observation, and the observation group was superior to the control group in the dental prosthesis (P<0.05). Experimental findings suggest that Ti-Zr-NB-Sn al oy for repair of dental defects has good biocompatibility and security.

OBJECTIVE:To observe the clinical efficacy of puerarin combined with β-aescine sodium in the treatment of pa-tients with postoperative edema of hand trauma. METHODS:118 patients with postoperative edema of hand trauma were random-ly divided into observation group (n=59) and control group (n=59) by number. Both groups were taken infrared physiotherapy and appropriate physical treatment such as hand functional exercise;patients in control group was added β-aescine sodium 10 mg based on the physical treatment,iv,once a day;observation group was added puerarin 200 mg based on the treatment of control group,iv,once a day. Both groups were taken 10 days for one course of treatment. Compared the swelling scores,perimeter of suf-fered limb and edema scores,clinical efficacy and adverse reactions of patients between the two groups before and after treatment. RESULTS:The symptoms of hand limb swelling in 2 groups were obviously improved(P<0.01 or P<0.05),however,observa-tion group was better than that of control group,with significant difference(P<0.05);after treatment,the swelling,perimeter of suffered limb and swelling score in observation group were lower than control group,with significant differences(P<0.05);the to-tal effective rate in observation group was 94.91% and control group was 83.05%,with significant difference(P<0.05). No ADR was found in 2 groups. CONCLUSIONS:Puerarin combination with β-aescine sodium has obvious efficacy and safety in the treat-ment of postoperative edema of hand trauma.

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.
