ObjectiveTo study the impact of high chromium yeast on type 2 diabetic mice.MethodsA total of 60 Balb/C mice were used in this study.Fifty mice were injected with streptozotocin to induce type 2 diabetes,while the ten mice without injection were in the normal group.The type 2 diabetic mice were divided into 5groups according to their fasting blood sugar levels,including 3 groups receiving high chromium yeast at low [250μg/ (kg· d)],medium [500 μg/ (kg,d)],and high [1000 μg/ (kg· d)] doses,1 group receiving metformin ( positive control),and 1 group receiving normal yeast ( negative control).The yeast or metformin were given through by gastric lavage daily for 15 weeks.Body mass and blood biochemical indexes (fasting blood glucose,glucose tolerance,etc) were determined,and the pathological examination of pancreas was conducted.Results Compared with negative control group,medium dose high chromium yeast group had significantly lower triglyceride ( P =0.043 ),low and medium dose groups had lower total cholesterol ( P =0.006,P =0.003 ),low and high dose groups had higher insulin levels (P =0.011,P =0.002),and high dose group had significantly reduced glycosylated hemoglobin (P =0.027).Pathological examination of pancreatic islets revealed that medium and high dose groups did not develop infiltration of inflammatory cells.ConclusionsHigh chromium yeast may improve type 2 diabetes mellitus.Further studies are needed to confirm the conclusion of this study with an organic chromium control group.

Objective To investigate the protection effects of teprenone in aspirin-induced gastric mucosa injury.Methods From 2008 to 2010,a total of 296 patients who took aspirin for the first time at the Department of Cardiovascular,First Hospital Affiliated to Zhejiang Chinese Medicine University were randomly divided into two groups.There were 166 cases in aspirin group,which took aspirin 100mg daily; 130 cases in aspirin and teprenone group,the aspirin dose equivalent with aspirin group and took teprenone 50mg/time,3 times/day orally.Gastrointestinal symptoms and gastric mucosa injury of patients in these two group were inspected at 3 month,6 month and 1 year.Results A total of 143 cases were recruited in aspirin group and 118 cases in aspirin and teprenone group.After taking medicine for 3 months,the occurrence rate of gastrointestinal symptoms in aspirin group was 1.40 ％.Compared with aspirin and teprenone group,the difference was statistical significant (0,x2 =1.663,P＝ 0.197).Follow up after taking medicine for 6 months,the occurrence rate of gastrointestinal symptoms in aspirin group was 4.96％.Compared with aspirin and teprenone group,the difference was statistical significant (0,x2 ＝6.021,P＝0.014).Follow up after taking medicine for 1 year,the occurrence rate of gastrointestinal symptoms in aspirin group was 20.15 ％.Compared with aspirin and teprenone group,the difference was statistical significant (1.69％,x2 =20.984,P=0.001).Compared with aspirin group,the symptom and endoscopy score of aspirin and teprenone group decreased significantly at follow-up for 6 months and 1 year (P＜0.05; P＜0.01 ).Compared with at 6 month,the symptom and endoscopy score of aspirin group at 1 year increased significantly (P＜0.05 ; P＜0.01).Conclusion Teprenone has certain protection effects in aspirin-induced gastric mucosa injury.Long-term use of conventional doses of aspirin may cause vary degrees of gastric mucosal injury,and the gastric mucosal injury get more severe as the time of taking medicine increases.

Objective To assess the safety and the efficacy of endoscopic ultrasound (EUS)-guided transmural drainage of pancreatic pseudocysts (PPC).Methods A total of 17 patients with PPC who underwent EUS to detect the optimal site and depth of puncture.The needle was punctured into the PPC cavity through endoscopic biopsy hole,cyst fluid was drained with a syringe.The guide wire was inserted along the pinhole under X-ray,and then the needle-knife was sent along the guide wire to cut the gastric wall and pseudocysts wall,followed by balloon dilation.The way of drainage was selected according to the cyst fluid properties.The technical success rate,treatment success rate,complication occurring rate and the skills were evaluated.Results Four patients were with nasalcystic catheter drainage,9 patients with double pigtail stents internal drainage,and 4 patients with nasal-cystic catheter and double pigtail stents combination drainage.The treatment success rates were 3/4,7/9,and 4/4 respectively.Only 1 patient subsequently developed bleeding from puncture site after stent successively placed,and was turned to surgery because of ineffective endoscopic treatment.Infection occurred in 4 patients during drainage,two of those were switched to surgical resection due to poor medical treatment response,and the other 2 were cured with intravenous infusion of antibiotics sensitive to cyst fluid bacteria and metronidazole rinse PPC.The median follow-up duration was 28.5months,and there was none of recurrence.Conclusions EUS-guided transmural drainage of PPC is safe.Stent placement and nasal-cystic catheter play an important role in PPC treatment.

BACKGROUND: Recently, the survival rate of premature infants increases year by year, but the cerebral growth of premature infants is immature, so the intellectual development of premature infants is slower than that of normal infants.OBJECTIVE: To explore the effect of family-oriented early intervention,which took material nutrition, information stimulation and petting as main interventional content, on level of intellectual development in premature infants in infantile age.DESIGN: Randomized sampling controlled observation.SETTING: Department of Pediatrics, Clinical Medical College of ShanPARTICIPANTS: Totally 35 premature infants of 31-36 weeks (18 males and 17 females) were enrolled as early interventional subjects, who were born at Jinan Municipal Central Hospital between May 2000 and July 2002. Meanwhile, 33 premature infants of 31-36 weeks (18 males and 15females) born in the same period and 49 mature neonates (26 males and 23females) were enrolled in control group.METHODS: The family-oriented early intervention, which considered nutrition, information stimulation and petting as chief interventional content,were performed in premature infants, and health archives was established.Taction and point massage were conducted. Home visit was done twice in one month. One routine health examination was determined at 3, 6 and 10months in the two control groups. The level of intellectual development was assessed in infants of 10-month old of each group with Gesell Developmental Schedules (GDS) and Japanese S-M Social Living Ability Scale.MAIN OUTCOME MEASURES: Evaluation of level of intellectual development in infants of each group.RESULTS: In the premature interventional group, 1 premature infant died, 2 withdrew from the study, and 32 eligible cases with the eligible rate of 91.4%; Among the 33 premature infants in the premature control group, there were 3 withdrawing from the study, and 30 eligible cases with the eligible rate of 90.9%. Among the 49 infants in the term infant control group, there were 3 withdrawing from the study and 46 eligible cases with the eligible rate of 93.9%. ①Developmental quotient (DQ) at each area of Gesell and evaluation of Japanese S-M Social Living Ability Scale were significantly higher in the premature interventional group than those in the premature control group at 10 months old. There were extremely significant differences in suitability, fine activity, language and individual social behavior. ②DQ at each area of Gesell and evaluation result of Japanese S-M Social Living Ability Scale were lower in the premature interventional group than those in the term infant control group at 10 months old, which had obvious difference. ③Evaluation in premature infants aged oyer 35 weeks of the interventional group was lower than that in the term infant control group, but there was insignificant difference (P ＞ 0.05).CONCLUSION: Early intervention has a marked effect in improving the intellectual developme nt of premature infants, and some premature infants can recover to the level of term infants in intelligence development after intervention.

High altitude retinopathy ( HAR ) refers to the body which can't adapt to the hypobaric hypoxia environment at high altitude leading to retinal diseases, which typically manifested as retinal hemorrhages, optic disc edema and cotton wool spots. With the development of high altitude medicine, HAR become a hot topic of eye research in recent years. New researches show a significantly higher incidence of HAR, and HAR has a close contact with acute mountain sickness, high altitude cerebral edema and high altitude pulmonary edema. A further study in pathogenesis and prevention measures of HAR will promote the prevention of altitude sickness. Traditional Chinese Medicine has achieved good effects in the prevention of altitude sickness, but the effect and mechanism of herbs on HAR has not been reported. Through read and summarize the relevant literatures and reports, the author will give an overview of the research advances on HAR's pathogenesis and application of Traditional Chinese Medicine.

Both aspirin and angiotensin converting enzyme (ACE) inhibitors are often used concomitantly in patients with cardiovascular disease. The safety of the combination has been questioned. The potential antagonistic interactions between ACE inhibitors and aspirin has become the focus of both increasing research and intense debate, with conflicting conclusions having been reported in the literature. We reviewed systematically available literature on the interactions between ACE inhibitors and aspirin in hypertension, acute myocardial infarction and congestive heart failure and found that further trials are needed to shed light on the effects and mechanism of interaction between these drugs.
