Objective:To evaluate the effect of reduction by leverage with minimally invasive and internal fixation with Ideal Compression Screw to treat fracture of calcaneus.Methods:13 patients(17 fee)twith fracture of calcaneus were treated by reduction by leverage with minimally invasive and internal fixation with Ideal Compression Screw.According to Sanders'classification,10 sides were classified as typeⅡfracture and 7 sides as typeⅢfracture.Results:The post-operative functional evaluation by American Orthopaedic Foot and Ankle Society ankle score system revealed excellent outcomes in 12 feet(70.6%),good in 3(17.6%),fair in 2(11.8%).The excellent rate was 88.2%.Conclusion:Reduction by leverage with minimally invasive and internal fixation with Ideal Compression Screw to treat fracture of calcaneus is an effective and micro-invasive method in treatment of fractures of calcaneus.The technique can contribute to sta-ble fixation,low operation complication and high rate of excellent to good outcomes,et al.

A high sensitive hydride generation ( HG) atomic fluorescence spectrometric system was developed using high current microsecond pulsed hollow cathode lamp ( HCMP-HCL) as the excitation source and its performance was evaluated. Test results confirmed that the excitation source could give out intensive atomic spectral lines. System precision (RSD, n=7) was 1. 1% for arsenic and 1. 4% for selenium. Detection limits (DLs, 3) were 0. 0066 μg/L and 0. 0075 μg/L, respectively. The developed AFS system was proved to have high reliability, low detection limit and remarkable improvement of analysis capability compared with that of commercial AFS instruments.

There are also many unanswered questions on the duodenogastroesophageal reflux(DGER),though it has been studied for more than 100 years.Based on the references and our studies,we reviewed the bile' injury on esophageal mucosal epithelial cells,the diagnosis and treatment of bile reflux into esophagus.The relationships of the biles with Barrett's esophagus and esophageal adenocarcinoma were elucidated especially.

The purpose of this investigation is to evaluate the excitability of the sympathetic nerves in burned rats. Pre ganglionic discharges from the cervical and the epinephronic sympathetic nerves and post-ganglionic discharges from the renal sympathetic nerve fibers were recorded in rats anaesthized with urethane. After burning, the discharges of the sympathetic nerves of the rats at first showed continuous high frequency soon followed by a decline. After that, the sympathetic efferent electrical activity became very active again, displaying a high amplitude and high frequency.These results suggest that the sympathetic nerves system exhibits periodic excitatory changes in burned rats with a excitation-inhibition-excitation cycle.

S-adenosylmethionine(SAM) is a physiologically active molecule in all the organizations and the human body fluids, and it is important to participate in a variety of biochemical reactions, the regulation of liver regeneration, liver cells differentiation and various sensitivity of the injury. The SAM affects the liver through a variety of ways. It is confirmed that the SAM and MTA can block the LPS-induced TNF-α of Kupffer cells to protect the liver. In a word, S-adenosylmethionine may be beneficial to LPS-induced liver in-jury in clinical treatment.

Objective To analyse clinical effects and influence on serum creatinine and blood urea nitrogen of Danggui Niantong pill in treatment of gouty nephropathy. Methods 80 patients with gouty nephropathy were divided into two groups and each with 40 cases.The control group were treated with general therapy,and observation group was treated another with Danggui Niantong pill. Results After treatment,effective rate of observation group was 92.50％,higher than that of control group 72.50％(P<0.05).After treatment,renal function serum markers and urine related factors level of observation group were lower than control group(P<0.05).ESR,WBC and N level of observation group were lower than that of control group(P<0.05).The proportion of adverse reactions of observation group was 15.00％ and control group was 12.50％.Conclusion Danggui Niantong pill can improve clinical effects of gouty nephropathy,reduce renal damage amd does not increase adverse reactions.

Objective To explore the effects of puerarin on proliferation ,invasion ,migration and tube formation in human endo-thelial cells and its possible mechanism .Methods The effect of puerarin on cell proliferation was determined using methyl thiazolyl tetrazolium(MTT) assay .Invasion was evaluated with transwell chamber .Migration was performed by the wound healing method . Endothelial tube formation was performed by tube formation assay .The expressions of phosphorylase Akt(p-Akt) and phosphoryl-ase nitric oxide synthase(p-eNOS) protein were determined by western blot .Results Puerarin promote the proliferation ,invasion , migration and tube formation of human endothelial cells(P<0 .05) .The expression of p-Akt and p-eNOS were increased signifi-cantly(P<0 .05) .Conclusion Puerarin can promote the proliferation ,invasion ,migration and tube formation of human endothelial cells .Up regulation of p-AKT and p-eNOS protein may be one of its mechanisms .

Objective To explore the effect and mechanism of aerobic exercise on islet β-cells in type 2 diabetic rats.Methods Thirty healthy SPF 8-week old Wistar rats were randomly divided into control group (C, n=10), diabetic control groups (DMC) and diabetic exercise (DME) groups, 10 rats in each group, among which 7 successful rat models were used in the experiment.The diabetic rat model was established by high fat and sugar diet and i.p.injection of streptozotocin in a dose of 50 mg/kg.The rats of group DME were forced to perform 20 m/min running for 30 min, once a day, 6 days in a week, for 8 weeks.Other rats were allowed free movement.At the end of experiment, serum glucose and insulin were measured and homeostasis model assessment (HOMA) was calculated, and pancreatic tissue samples were collected for histopathological examination.The morphology and structure of pancreatic islets were observed under a digital microscope, the perimeter and area of islets were analyzed by image analysis, and shape factor of islets was calculated.The insulin content, glucokinase and ultramicro-ATPase activity in the pancreatic homogenate were determined.Results In the DME group, the perimeter and area of islets were significantly higher than the DMC group (P< 0.05), but still lower than the control group.The shape factor was significantly increased, the cell hypertrophy, vacuolization and nuclear pyknosis were markedly alleviated than those in the DMC group, the insulin content, glucokinase and the trace total ATP activity in the DME group were significantly higher than those in the DMC group (P<0.05), and the SF and HOMA were significantly changed.Conclusions Aerobic exercise can reduce the blood glucose level, improve the morphology of islets and β-cells in the type 2 diabetic rats.It may be due to increase of the activity of glucose kinase and ATP-synthase, and increased insulin sensitivity in the pancreas.

Objective To describe the experience of nurses in combined care program of traditional Chinese medicine (TCM) and provide references for nursing managers. Methods The phenomenology research method was adopted in this study. Fourteen nurses who had achieved the combined care program of TCM participated in an in-depth interview. Data were analyzed by using phenomenological analysis. Results All nurses approved nursing program of TCM: finding sense of belonging in nursing work;demonstration of self-value;standardization of nursing tednnique;harmonious environmont of nursing work. But some defect still existed: too subjective evaluation item of nursing program of TCM;inappropriate evaluation table;lact of hospital characteristics of TCM nursing;deficiency of TCM knowledge. Conclusion Nursing managers should pay more attention to nurses' emotional experience, grasp the implementation of the problems during the program and improve the program, optimize the skills, provide trainings.
