AIM: To study the effects of guava polysaccharides on blood glucose level and antioxidant activity in alloxan-induced diabetic mice. METHODS: The animal model of diabetes was established by injecting alloxan into mice abdominal cavity.The mice were divided into five groups: normal control group,diabetic model group,guava polysaccharides group I,guava polysaccharides group II,glybenclamide group.Blood glucose level was determined with blood glucose monitor 3 d and 10 d after being given polysaccharides.The mice were anaesthetized and killed on the tenth day.Activity of SOD and concentration of MDA in blood serum and liver were determined. RESULTS: Compared with diabetic model group,the blood glucose level of guava polysaccharides group I and guava polysaccharides group II significantly decreased.Activity of T-SOD in blood serum and liver significantly increased,while concentration of MDA in blood serum and liver significantly decreased. CONCLUSION: Guava polysaccharides can significantly decrease blood glucose level and improve the antioxidant activity of diabetic mice.lt is a potential hypoglycemic agent.

Objective:To explore the impact of special rectification on antibiotics application in the patients during perioperative period with gynecologic typeⅡincision in our hospital. Methods:The antibiotics type, use frequency, expense, administration time, dosage, treatment course and combined medication were retrospectively compared between April to September in 2011(before the recti-fication) and April to September in 2013 (after the rectification). Results: After the special rectification, the total DDDs was de-creased from 1 564. 5 to 419. 3, the expense for antibiotics and all drugs was respectively decreased from (297. 5 ± 47. 1) yuan to (108. 3 ± 29. 6) yuan and (806. 4 ± 63. 1)yuan to (498. 1 ± 70. 2) yuan, the proportion of antibiotics was decreased from (36. 9 ± 9.1) % to (21.7 ±6.8) %, and the treatment course was reduced from (3.7 ±1.4)d to (1.5 ±0.6)d(P<0.05). The rational rate of administration time, dosage and combined medication was respectively increased from 67. 7% to 98. 6%, 81. 5% to 100. 0%and 41. 1% to 80. 7%(P<0. 05). Conclusion:Special rectification can effectively improve the rational antibiotics use in gynecology department of our hospital during perioperative period of type Ⅱincision.

Currently, platelet transfusion is the primary treatment for thrombocytopnia which results from intensive chemotherapy and radiotherapy of cancer. While repeated platelet transfusions are associated with several problems. The clinical availability of safe and effective platelet growth factors is eagerly awaited. Currently, a mumber of hematopoietic growth factors with thrombopoietic activity have been identified. This review discusses the biological characteristics and the clinical trial investigation development of platelet growth factors.

AIM: To study the expression and change of growth hormone receptors in experimental cirrhotic liver in rats. METHODS: Thioacetamide-induced liver cirrhosis was developed in Sprague-Dawley rats. The expression of growth hormone receptor and its mRNA was investigated by radio-ligand binding assay, revere transcript-polymerase chain reaction (RT-PCR) and digital image analysis in liver tissue or hepatocytes taken from normal control or cirrhotic rats with different stages of cirrhosis. RESULTS: Growth hormone-specific singular binding sties, namely growth hormone receptors, were detected in liver tissue or hepatocytes from rat samples with cirrhosis. The binding capacity of growth hormone receptors in rat cirrhotic live tissue was significant lower than that in normal control, and it decreased gradually along with the accumulation of collagen in the process of formation and development of liver cirrhosis. The binding sites of growth hormone receptors in rat cirrhotic liver cells were significantly lower than that in normal control. The expression of growth hormone receptor mRNA in rat cirrhotic liver tissue was also significant lower than that in normal control. CONCLUSIONS: The growth hormone receptor was expressed in cirrhotic livers at a reduced level in isolated hepatocytes or live tissue of cirrhotic rats, and lesser expression of growth hormone receptors was found in later stage of cirrhosis. The suppressed expression of growth hormone receptor was partly due to the reduced expression of its mRNA in cirrhotic liver tissue.

50 mm/h were detected in all the patients. Decreasing C 3 in 6 patients and C 4 in 5 were found. Conclusions SLE is one of the general conditions causing retinal vein occlusion. Visual acuity and barrier of retinal vein and capillary are damaged seriously in patients with retinal vein occlusion caused by SLE, which may be accompanied with other ocular or general lesions. It is suggested that retinal vein occlusion is relative with SLE activity.

Objective To assess the characteristics of heart rate turbulencer (HRT) in elderly patients with decreased left ventricular diastolie function.Methods 40 patients were divided into two groups:20 patients with enlarged left atrium and 20 patients without enlarged left atrium.20 healthy people were selected as controls. Turbu1ence onset (TO) and turbulence slope (TS) were measured,and correlation was analyzed between TO,TS and the E/A,index of Macruz and heart rate variability (HRV).Results TO was higher (P<0.05) and TS was lower in patients (P<0.01),TO was higber in patients with enlarged left atrium than in with out enlarged lef atrium people (P<0.05) and TS was lower (P<0.01).TO was positively (P<0.01) and TS Was negatively (P<0.05),correlated with the index of Macruz.TO Was negatively (P<0.05) and TS was positively (P<0.05) related to SDNN and SDANN.Conclusion HRT can be used as a potential risk predictor in decreased left ventricular diastolic function patients.

Hyponatremia is the most common electrolyte imbalance.Other than neurological complications,other complications of hyponatremia have not received due attention.Mild,chronic hyponatremia can result in subtle symptoms such as gait disturbance and falls,and increase the risks of osteoporosis and fractures.This paper reviewed the emerging relationship between hyponatremia and bone metabolism,its possible mechanisms and clinical implications.

Objective To investigate the effect of melatonin(MT)on tau hyperphosphorylation in hippocampus of mice with exposure to lead(Pb)at early development stage and its possible mechanism.Methods Healthy C57BL/6 mice were randomly divided into four groups:control group(received normal water),lead exposure group(exposed to 0.2% Pb acetate from postnatal day 1(PND 1)to PND 21 through drinking water),MT group(received 50 mg/mL MT through drinking water since 12-month-old for 3 months)and MT combined with lead exposure group(exposed to 0.2% Pb acetate from PND 1 to PND 21 and then given 50 mg/mL MT since 12-month-old for 3 months through drinking water).The Pb levels in the blood and hippocampus were determined by graphite furnace atomic absorption spectrometry.Morris water maze was used to detect the spatial learning and memory.The phosphorylation level of tau and the protein level of GRP78 and CHOP in hippocampus were detected by Western blotting.Results Compared with the control group,the Pb levels in the blood and hippocampus were significantly increased in lead exposure group(P<0.05),while MT treatment did not affect the Pb levels both in the blood and hippocampus.In the lead exposure group,the phosphorylation level of tau in the hippocampus was significantly increased compared with control group(P<0.01),and after treatment with MT,the phosphorylation level of tau in MT combined with lead exposure group was significantly decreased compared with the lead exposure group(P<0.05).Furthermore,the expression of GRP78 and CHOP in the hippocampus was significantly higher in lead exposure group than in control group(P<0.05),and after treatment with MT,the expression levels of GRP78 and CHOP were lower than those of the control group.Conclusion MT can ameliorate the phosphorylation level of tau in the hippocampus and defects of learning and memory in C57BL/6 mice with exposure to lead at early development stage,and this may be related with the modulation of endoplasmic reticulum stress.
