Objective To evaluate percutaneous kyphoplasty in the treatment of fresh osteoporotic vertebral compression fractures. Methods Thirty patients,aged 65 -81 years (mean 72 years),were enrolled in this prospective and consecutive Cohort study. All patients suffered from solitary fresh osteoporotic thoracolumbar vertebral compression fracture (T8 -L4) without neurological dysfunction. Percutaneous kyphoplasty with balloon dilatation was performed and a follow-up of 12 months was made. Results Significant improvement in kyphotic angle was obtained after the treatment,which was reduced from 12.5? before the surgery to 6.6? after the surgery. The visual analog scale concerning the back pain was also reduced from 8.2 before the surgery to 1.6 after the surgery. Conclusion For the treatment of fresh osteoporotic vertebral compression fractures,percutaneous kyphoplasty can achieve excellent therapeutic results.

Objective To explore the effects of Baogan Jiedu Granule on lipid peroxidation of free radicals in acute liver injury mice induced by tripterygium glycosides.Methods Totally 60 mice were randomly divided into tripterygium glycosides model group,large-dose,medium-dose and small-dose groups of Baogan Jiedu Granule,Ganlixin group and control group.Each group was respectively perfused with the corresponding drug for 5 days and tripterygium glycosides were perfused once to make the model.The serum levels of ALT,AST,SOD,MDA and GSH-Px were measured.Results The serum levels of SOD and GSH-Px in model group decreased and MDA rose obviously.Compared with model group,Baogan Jiedu Granule of all doses could effectively decrease ALT,AST and MDA level and obviously improve GSH-Px level in each group.In addition,in the large-dose group SOD level was markedly improved(P

Objective To develop the formulation of self-microemulsifying drug delivery system for hawthorn leaves flavonoids (HAW-SMEDDS). Methods The optimum formulations of oil phase, surfactant, and assistant surfactant for HAW-SMEDDS were screened by solubility test, compatibility test, and pseudo-ternary phase diagrams, with the time of formulating microemulsion, the consequence of visual examination, and particle size as indexes. The dissolution of HAW-SMEDDS was measured, taking the commercial tablet Yixintong Tablet as reference. Results The optimum self-microemulsifying drug delivery system was composed of Labrasol (35%), Transcutol P (10%). The particle diameter was (39.5?5.4) nm, the time of self-microemulsifying was less than 1 min. The percent of accumulated dissolution of hawthorn leaves flavonoids in SMEDDS in distilled water was up to 70% at 10 min, while that in the Yixintong Tablet was less than 50% at 60 min. Conclusion The formulation of HAW-SMEDDS preparation could meet the request of the design. It could provide the reference for the new dosage form.

Objective To describe characteristics of adult respiratory tract influenza virus A (INFA)infection.Method 804 adult patients with acute respiratory tract infections were enrolled and 156 cases of healthy adults were concomitantly selected. Enzyme-linked immunoabsorbent assay was used to measure INFA serum specific IgM antibody.Result (1)In the total patients , 17.6% had positive INFA-IgM,significantly higher than the control(P

Objective To evaluate the accuracy of remifentanil target-controlled infusion (TCI) system in children.Methods Thirty ASA Ⅰ patients, aged 3-12 yr, weighing 10-40 kg, scheduled for elective ear-nosethroat or urological surgery, were randomly divided into 2 groups with 15 patients in each group:2 ng/ml remifentanil group (group Ⅰ) and 4 ng/ml remifentanil group (group Ⅱ). Anesthesia was induced with iv injection of propofol 2 mg/kg and TCI of remifentanil. Remifentanil was administered with a specific TCI system incorporating the pharmacokinetic parameters of Minto.The target plasma concentrations of remifentanil were set at 2 or 4 ng/ml. Tracheal intubation was facilitated with vecuronium 0.1 mg/kg after the children lost consciousness. The children were mechanically ventilated.Anesthesia was maintained with TCI of remifentanil, iv infusion of propofol and intermittent iv boluses of vecuronium. The target plasma concentration of remifentanil remained unchanged and bispectral index value was maintained at 45-65 or auditory evoked potentials index value ＜ 30 by adusting the infusion rate of propofol.Arterial blood samples were taken at 5, 10, 20, 30, 40, 50 and 60 min after TCI remifentanil was stared for determination of blood remifentanil concentrations by high performance liquid chromatography. Median prediction performance error (MDPE),median absolute performance error (MDAPE) and wobble of remifentanil TCI system were calculated. Results The measured concentrations of remifentanil were significantly higher than the target plasma concentrations in both groups (P＜0.05). The MDPE, MDAPE and wobble were 20.0% , 30.0% and 25.0% respectively in group Ⅰ , and 17.5%, 17.5% and 12.5% respectively in group Ⅱ . TheMDAPE and wobble were significantly decreased in group Ⅱ compared with group Ⅰ(P＜0.05).Conclusion When remifentanil is administered using a specific TCI system incorporating the pharmacokinetic parameters of Minto in children of 3-12 years old, the accuracy is not high.

Aim To study the effects of ferulic acid (FA) on E-selectin expression in human umbilical vein endothelial cells (HUVECs) activated by lipopolysaccharide and leukocyte-endothelial cell adhesion. Methods The effects of FA on E-selectin and E-selectin mRNA expression were determined by flow cytometry and reverse transcription polymerase chain reaction. The effect of FA on HL60-HUVEC adhesion was evaluated with the method of staining the cells by Rose Bengal. Results The expression of tively). Conclusion FA can inhibit the expression of E-selectin and E-selectin mRNA and HL60-HUVEC adhesion. This may contribute to its protective effect against ischemia-reperfusion injury.

Objective To investigate the clinical efficacy of selenium-enriched garlic on patients with oligoasthenospermia.Methods From October 2012 to August 2013,160 patients with oligoasthenospermia were randomly divided into two groups.Treatment measurements for 80 patients in the control group included oral treatment of Shengjing capsules 1.6 g/time Tid,Vit-E soft capsules 100 mg/time Tid,and took Vit-B 0.2 g/time Tid,for three months.Treatment measurements for 80 patients in the treatment group included oral treatment of selenium-enriched garlic in addition to all the above,for three months.We observed the changes of the semen quality indexes (including semen volume,sperm density,motility,survival rate,etc.) of two groups before and after treatment.Results Sperm quality was improved after treatment in both groups.All indices in the treatment group were significantly higher than those in the control group (P ＜ 0.05).Conclusions For patients with male infertility caused by oligoasthenospermia,The use of combination of selenium-enriched garlic and Shengjing capsules can improve the quality of sperm.

AIM: To investigate the expression of peroxisome proliferator-activated receptors (PPARs) in human endothelial cells, and their effects on plasminogen activator inhibitor-1 transcription. METHODS: The expression of three types of PPARs in mRNA level were detected in human umbilical vein endothelial cells(HUVECs) by using RT-PCR. Cultured endothelial cells line-ECV304 were transfected with PAI-1 promoter controlling CAT reporter gene and co-transfected with varying doses (250, 500, 1 000 ng) of expression vectors PPAR? or PPAR?.The transcripton activity of PAI-1 promoter were detected with ELISA. RESULTS: There were all three types of PPARs mRNA expression in HUVECs, while the expression of PPAR? was less than that of PPAR?( P

The development of muscle strength evaluating system based on Android system was developed in this research. The system consists of a lower unit and an intelligent mobile terminal. The pressure sensor of the lower unit was used to collect muscle strength parameters. And the parameters were sent to the Android device through the wireless Bluetooth serial port. Then the Android device would send the parameters to the doctor monitored platform through the Internet. The system realized analyzing the muscle strength parameters and real-time displaying them. After it ran on the Android mobile phones, it showed an effective result which proved that the system combined with mobile platform could make more convenient for the patients to assess their own muscle strength. It also provided reliable data references for doctors to know the patients' rehabilitation condition and to make the next rehabilitation plan.
