Objective To observe the clinical efficacy and safety of application of lafutidine treated in curing peptic ulcer.Methods Eighty-four patients with peptic ulcer were randomly assigned to receive either lafutidine(10 mg) twice daily in 42 patients of cured group or lansoprazole (30 mg) once daily for 4 weeks in 42 patients of control group.Ulcer healing rate and clinical performance were examined after treatment.Results The first,third and seventh day of peptic ulcer healing rate were 38.09％ (16/42), 71.42％ (30/42) and 90.47％ (38/42) in the lansoprazole group and 23.81％ (10/42), 76.19％ (32/42) and 85.71％ (36/42) in the lafutidine group.There were no siginificant difference between two groups (P =0.157,0.620, 0.736).Gastroscope examination showed the complete healing rate, average healing rate and general clinical effectiveness were 61.90％(26/42) ,30.95％(13/42) and 97.61％(41/42) in the lansoprazole group,while the number for lafutidine group were 57.14％ (24/42), 28.57％ (12/42) and 95.23％ (40/42).There were no siginificant difference between two groups (P =0.657, 0.811, 1.000).No severe side-effect was occurred in both groups.Conclusion Use Lafutidine to cure peptic ulcer can promote healing effectively, improve patients' clinical symptoms which is similar to lansoprazole.

Objective To observe the influence of short-term continuous subcutaneous insulin infusion(CSII)on ?-cell function in newly diagnosed type 2 diabetes(T2DM).Methods A total of 32 inpatients with newly diagnosed T2DM who had a 14-day course of CSII were randomly assigned to two groups of OGTT and arginine stimulating test(AST).Before and after 3 days and 14 days CSII treatments,OGTT and AST were performed respectively.The changes of the values of plasma glucose,HOMA-IR,HOMA-? and △C30/△G30,△C120/△G120 or arginine-induced acute C-peptide reaction(ACRARG)in two groups were compared.Results In OGTT,the values of plasma glucose and HOMA-IR were decreased,HOMA-? and △C120/△G120 were increased significantly after CSII therapy,both in day 3 and day 14;and △C30/△G30 were unchanged after 3 days but increased markedly after 14 days.However,in ACRARG,the above mentioned parameters almost remained unchanged after CSII treatment in 3 days or 14 days.Conclusions In newly diagnosed T2DM with elevated fasting glucose levels,intensive insulin therapy can partly improve ?-cell function showed by OGTT,not by AST.

Simple sequence repeat (SSR) was used to investigate the genetic diversity and structure of Dendrobium officinale. A total of 15 primer pairs with stable and repeatable polymorphism were screened out from 60 SSR primer pairs developed by the method of microsatellite enrichment by magnetic beads. Forty-eight samples of Dendrobium officinale were analyzed in genetic polymorphism. These loci were polymorphic and displayed 3 to 9 alleles per locus with a mean number of 6.1. The observed and expected heterozygosities ranged from 0.60 to 0.85 and from 0.49 to 0.85 respectively. The polymorphic information content (PIC) of each SSR locus varied from 0.437 to 0.829 with an average of 0.702. Fifteen primer pairs were used in Dendrobium cross-species amplification and totally 13 primer pairs were proved to have the transferability in D. officinale related species. In addition, 500 tissue culture plantlets of D. officinale were tested for purity identification by means of PCR amplification with four SSR primer pairs. The results showed that SSR technique is a feasible, simple and inexpensive method for determining adulterants in germplasm identification.

BACKGROUND: Previous studies demonstrated that eucommia bark can promote bone marrow stern cells (BMSCs) differentiated into osteoblasts, but relative mechanism is poorly understood. OBJECTIVE: To investigate the effects of eucommia bark water/methanol extracts on expressions of osteopontin (OPN) and osteoprotegedn (OPG) in rat BMSCs. METHODS: Totally 2 g eucommia bark powder were added into water or methanol to 16 mL and oscillated for 1 hour at room temperature. After soaked overnight, both extracts were centrifuged at 15 000 r/min for 10 minutes. Water extract was obtained from supernatant in water soaked powder. In methanol soaked powder, methanol extracts was obtained by concentrated supernatant in vacuo and resolved using 16 mL water. Water and methanol extracts were then filtered by 0.22 μm membrane, and conserved at -20℃. Six SD rats, aged 2 months, were selected, and the 3~(rd)passage of BMSCs were induced by water or methanol extracts with dilution of 1 × 10~(-2), 1 × 10~(-3), 1 × 10~(-4) and 1 × 10~(-5), respectively. PBS was added in the negative control group. All cells were cultured for 6 days. Expressions of OPN and OPG was measured by immunocytochemistry at 6 days with induction. The expression of OPN and OPG induced by water and methanol at 1 ×10~(-3) and 1×10~(-4) dilution was detected by RT-PCR. RESULTS AND CONCLUSION: Immunocytochemistrical results indicated that both water and methanol extracts of eucommia bark simulated OPN and OPG expression, in particular with dilution of 1×10~(-4). The methanol extracts had a stronger effect than water extract, but the expression of OPG did not change obviously. RT-PCR demonstrated that at the 3rd day of inducement, the level of OPN expression induced by water extract was higher than that of methanol extract, and no OPG expression was detected. Osteogenic differentiation of rat MSCs induced by eucommia bark water/methanol extracts relates to stimulating expression of OPN, which has no correlation to OPG. OPN expression induced by water extract is early than that of methanol extract.

Aim To establish two new rat models of visceral hypersensitivity in IBS by two chemical irritants.Methods Acetic acid or mustard was infused for six days in intestines of adult rats.After modeling,the rectal distention was performed and the thresholds of abdominal withdrawal reflex were measured.The frequency,peak value,peak-nadir value and area of the gastric and enteric electrical activity were recorded.And the contents of 5-HT in the blood serum were detected.Results Compared with the control group,the colon and rectum's sensitivity(P<0.05)and the frequency(P<0.01) of the acetic acid model were heightened.Meanwhile,the colon and rectum's sensitivity(P<0.01),the frequency(P<0.01),peak value(P<0.05),peak-nadir value(P<0.01)and area(P<0.01),and the contents of 5-HT(P<0.05)in serum of the mustard model were all changed,which indicated the increasing of sensitivity of the model.The colon and rectum's sensitivity,the gastric and enteric electrical activity and the contents of 5-HT in serum of the proving group were recovered to some extent.Conclusion The new rat model of visceral hypersensitivity in IBS is successfully set up by stimulating the intestines of adult rats with chemical substances.
