Objective To find out the change of bone density in premenopausal women with systemic scleroderma (SSc) and its association with gluecorticosteroid.Methods Using a clinical bone densitometer manufactured by British McCue CuBA Cobroadband ultrasound attenuation (BUA) and velocity of sound (VOS) were measured at the left heel bone in 58 premenopausal patients with systemic scleroderma.Among them,35 patients had taken gluecorticosteroid,and the other 23 had not.Levels of serum estradiol (E 2) in 19 out of 58 patients with systemic scleroderma were determined and compared with healthy controls.Results Levels of broadband ultrasound attenuation and velocity of sound measured in permenopausal patients with systemic scleroderma who had taken gluecorticosteroid were significantly lower than those in ones who had not taken gluecorticoseroid ( P 0 05).Conclusion The bone mineral density and the level of BUA and VOS in premenopausal patients with systemic scleroderma,who had taken gluecorticosteroid,are obviously decreased,but there is no significant difference between patients without taking gluecorticosteroid and healthy controls.It indicates that systemic scleroderma is no dangerous factor of osteoporosis.And bone density in premenopausal patients with systemic scleroderma is related with the patients who have taken gluecorticosteroid for a long time.

Objective To observe the changes in gut mucosal barrier and gut-origin bacteria-endotoxin translocation in acute necrotizing pancreatitis (ANP) rats. Methods Wistar rats were divided randomly into normal group (n=6), sham operation group (n=30) and ANP group (n=39). ANP was introduced by infusion of artificial bile into biliopancreatic duct. Morphology of pancreas and intestine were observed and tight junction on ileum epithelia were assessed by cryofracture replicas electroscopy. Plasma levels of D-lactic acid and endotoxin were examined at various time points. The rates of bacterial translocation to abdominal organs were also calculated. Results Mucosal and tight junction damages of the gut were found during early stage of ANP. Simultaneously, plasma D-lactate levels increased and endotoxemia occurred. The rate of bacterial translocation to organs was 59.5% 72h after ANP occurred. Conclusions Gut barrier function can be injured in the early stage of ANP, and resulting in gut origin bacteria-endotoxin translocation, which may be the originator of systemic inflammatory reaction and secondary infection of the pancreas.

Objective To explore exenatide in the treatment of metformin(MET)alone,sulfonylurea (SU)alone or MET + SU combination therapy with poor glycemic control in type 2 diabetic pa-tients and to find effective nursing measures.Methods 24 patients were randomly divided into the con-trol group and the exenatide group with 12 patients in each group.In the exenatide group,exenatide 5μg twice a day for 4weeks,then 10μg twice a day for 12 weeks.Changes of HbAlc,body weight,BMI,FBG,P2hBG,and rate of adverse reaction were compared between two groups.Results Glycosylated hemoglobin (HbAlc),body weight,BMI,FBG,P2hBG in the control group before and after treatment showed no significant difference,while the exenatide group showed better results compared with those before treatment and the control group.Nursing intervention played evident effect on reducing adverse effect such as nausea,vomiting,diarrhea,low blood sugar,headache.Conclusions For patients with type 2 diabetes,using MET,SU alone or MET + SU combination therapy showed poor results of blood sugar control,addition of exenatide therapy can effectively control blood sugar,nursing intervention can significantly alleviate the adverse effects of patients.

In this study, modification technology by surface coating was used to improve the flowability of powder of Chinese herbs extracts. Seven kinds of powder of Chinese herbs extracts were coated with 1% silica nanoparticles using an under-driven Comil. The powder characteristics tester was used to evaluate the flowability of uncoated and coated powders. Surface morphology and particle size distribution of powders were compared by scanning electron microscope (SEM) and optical microscope. The powder hygroscopicity was also investigated. The results showed that, after modification, angle of repose, angle of spatula, compressibility and adhesiveness extremely decreased, and flowability index substantially increased, the powder flowability was significantly improved, especially Gegen and Dahuang extracts powders. Scanning electron microscopy images showed the distribution of silica nanoparticles on the host drug particle surfaces. There were no remarkable changes in the particle size distribution and hygroscopicity of all powders after coating. Therefore, Comilling for surface coating modification technology was an effective method to improve the flowability of Chinese herbs extracts and suggested a possible way forward to enhance the quality of Chinese drugs pharmaceutics in their study and manufacture.

Objective To explore the effect of diabetic liaison nurses on controlling blood sugar levels in patients with hyperglycemia in department other than endocrinology. Methods Four hundred diabetic patients with high blood sugar were selected from January to December, 2014 in department other than endocrinology. They were divided randomly into 2 groups equally:the control group and the observation group. The control group received traditional nursing care, while blood sugar management was carried out by diabetic liaison nurse in the observation group. Result Pre-discharge sugar metabolism in the observation group was significantly better than that in the control group (P<0.05). Conclusion The diabetic liaison nurses in other departments than the endocrinology department can help control blood sugar levels in patients with hyperglycemiain.

Extraction, purification and determination methods of glycyrrhizic acid in Licorice are surveyed in this paper. The extracting efficiency of dilute ethanol solvent for glycyrrhizic acid is higher than water extraction, and ammonia appended to ethanol solution can increase the effect of extraction. Ultrasound method, microwave-assisted method and supercritical CO2 fluid extraction are more effective than the conventional techniques, due to the short extraction time, low consumption of solution and energy. The modem analytical methods such as TLCs, HPLC and CE can determine the content of glycyrrhizic acid rapidly and exactly.

OBJECTIVE To investigate the protective effect and mechanisms of luteolin-7-O-β-d-glucuronide (LGU) on oxygen glucose deprivation (OGD)-induced H9C2 cardiomyocytes injury. METH-ODS The protective effect of LGU on OGD-induced H9C2 cardiomyocytes death were investigated by MTT assay. The microfilament change of H9C2 cardiomyocytes was detected by phalloidin staining and the lactate dehydrogenase (LDH) leakage rate was also detected by LDH kit. In order to explore the possible mechanisms of LGU, ATP content, intracellular Ca2+fluorescent intensity and concentra-tion, mitochondrial membrane potential (MMP)and the expressions of apoptosis-related proteins were detected by ATP kit,CLSM(Fluo-3/AM probe),Ca2+kit,CLSM(JC-1 probe)and western blotting meth-od, respectively. RESULTS The inhibition of H9C2 cardiomyocyte survival rate inducedby OGD was improvedby pretreated with LGU in a concentrationdependent manner. The microfilaments injury as well as the increase of LDH leakage rate were also improvedby pretreated with LGU.The ATP content was significantly decreased,intracellular Ca2+fluorescent intensity and concentration were significantly increased and the MMP was significantly decreased 4 hafter OGD. LGU significantly reversed the de-crease of intracellular ATP content,the increase of Ca2+fluorescent intensity and concentration and the decrease of MMP.The release of cytochrome C,the expressionsof caspase-9 and caspase-3 in H9C2 cardiomyocytes were increased 16 h after OGD.LGUsignificantly inhibited the changes of these apop-tosis-related proteins. CONCLUSION LGU has a significant protective effect against OGD-induced H9C2 cardiomyocytes injury through inhibiting calcium overload,increasing ATP content,improving mi-tochondrial function and inhibiting apoptosis.
