Repeat prescription is adopted in Singapore as a convenient measure for patients with chronic diseases.On the one hand, it can avoid patients''inconvenience caused by frequent visits to hospitals.On the other hand, it reduces the waste of medical resources.In recent years, Singapore has also been using modern technology and measures to expand the medication refill service actively in order to enhance work efficiency, reduce waiting time and promote drug safety, thus to improve patients'' satisfaction.With the increasing medical pressure and the deepening of medical reform, the repeat prescription model in Singapore shows positive enlightenment to China.

Objective To study the effect of fissure sealant combined with fluorine-containing gel in the prevention of dental caries in children.Methods Totally 86 cases who came into our hospital for healthy check-up from June 2010 to June 2011 were slected,and they were divided into 3 groups according to a random number table.Children in fissure sealant group were given fissure sealant treatment,children in combined treatment group were given fluorine gel treatment in addition of fissure sealant,and children of the control group were given rou-tine oral care.Observed the caries average,adjacent surface caries and caries occurrence of the three groups,and observed the blocking agent of the fissure sealant group and the combined treatment group.Results Three years after the prophylactic treatment,the caries occurrence, adjacent surface caries and caries average of fissure sealant group and combined treatment group showed an obvious downward trend compared with those of the control group.But the caries occurrence,adjacent surface caries and caries average of combined treatment group were sig-nificantly lower than the fissure sealant group,with a statistically significant difference(P <0.05).In the follow-up of the first two years,the complete preservation rate of sealant in the combined treatment group was significantly higher than the fissure sealant group,while the partial and complete loss rate of sealant in the combined treatment group was significantly lower than the fissure sealant group,and the difference was statistically significant (P <0.05).Conclusion Fissure sealant combined with fluorine-containing gel in the prevention of dental caries in children can receive good results,and it is worth of promotion.

Objective Discuss the treatment effect of sodium ferulate,deproteinized calf serum and high pressure oxygen on acute carbon monoxide poisoning.Methods Seventy-five cases with coma acute carbon monoxide poisoning were randomly divided into two groups:the treated group (37 cases) and the control group (38 cases).The two groups were treated with high pressure oxygen,high flow oxygen uptake and support treatment,The treated group were treated with sodium ferulate and deproteinized calf serum.The control group were treated with citicoline act medicaments.Result The occurrence and injury degree of myocardial damage and delayed encephalopathy were markedly attenuated (P ＜ 0.05),the time of coma was obviously decreased (P ＜0.01),the death rate was obviously difference (P ＜0.05) in the treated group compared with the control group.Conclusion Sodium ferulate,deproteinized calf serum injection possess obviously effect on acute carbon monoxide poisoning.

Objective:To search the English literatures on prescription refills for chronic diseases for a systemic analysis and to explore the mode and the management measures in order to develop the prescription refill and medication therapy management service for patients with chronic diseases in China .Methods:In the pubmed database , the literatures related to prescription refills published before April 2016 was retrieved.The literatures were analyzed by classification of country or region , the types of drugs and the other in-formation.Results:It was found that the United States , Britain and Sweden were the countries with the most prescription refills .The medications for hypertention , diabetes , hyperlipidemia and other chronic diseases respectively were the most types of medications men -tioned.Age, educational level, race, language, type of medication, and so on.were the factors that affected patient compliance . Pharmacists played a role in auditing , intervention and follow-up in prescription refills programs .Conclusion: The programs of pre-scription refills is well developed in America and Europe , which may be a good way to solve the demand in long-term caremedication therapy for those patients in China .

OBJECTIVETo evaluate the roles of folic acid and beta-carotene in the chemoprevention of gastric and other gastrointestinal (GI) cancers.

METHODSIn a randomized, double-blind, placebo-controlled trial, a total of 216 patients with atrophic gastritis were randomly assigned to one of the four groups: (1) folate (FA, 20 mg per day plus vitamin B(12) 1 mg, intramuscularly, per month for one year, then 20 mg two times a week plus 1 mg per three months for the next year); (2) natural beta-carotene (N-betaC, 30 mg per day for first year, then 30 mg two times a week for the next); (3) synthetic beta-carotene (S-betaC, administered as in N-betaC); and (4) placebo. Follow-ups continued from 1994 to 2001.

RESULTSA total of 7 new cases of gastrointestinal cancers were diagnosed with 3 stomach, 1 colon and 1 esophageal cancers occurring in the placebo group; 1 stomach cancer in both of the N-betaC and S-betaC groups, and no cancer occurring in FA group. In terms of GI cancers, there was a significant reduction in the FA group, compared with the placebo group (P = 0.04). A similar trend was observed in both N-betaC and S-betaC groups (P = 0.07 - 0.08). Taken together, the three intervention groups displayed a highly significant decrease in occurrence (P = 0.004, vs placebo), and a lower risk for GI cancers (OR = 0.12; 95% confidence interval, 0.03 - 0.51). For development of gastric cancer, any one of the three active-treated groups did not reach statistically significant reduction. The FA group showed obvious improvement of the gastric mucosal lesions with more patients displaying lesions reversed or stable atrophy and inflammation (P = 0.04), reversed intestinal metaplasia (P = 0.06) at the end of follow-up, and reversed displasia (P = 0.017) at 12 months. Two cases of false jaundice were found in beta-carotene groups with no influence on administration, and no side-effects were reported in FA group.

CONCLUSIONSThis trial revealed the interventional effect of folic acid on the development of GI cancers, a similar effect of beta-carotene was also detected. Also, folic acid may be of use to treat atrophic gastritis by preventing or reversing the precancerous lesions.
