Objective To investigate the serum level of C reactive protein(CRP) in the hypertension patients with heart function impairment.Methods 68 hypertension patients who had no,mild or severe heart function impairment were se- lected and accordingly divided into 3 groups,while 30 healthy subjects served as normal controls.The levels of HS-CRP and LVEF was measured.Results All the hypertension patients had a high CRP level than normal controls(P

Objective Low-dose naloxone has been shown to reduce side-effects of morphine while morphine analgesia is not antagonized and may even be enhanced. The purpose of this study was to evaluate the effects of low-dose naloxone infusion (50 ng? kg-1? h-1 ) on morphine analgesia and plasma levels of opioid peptides in patients after abdominal hysterectomy.Methods Forty-two ASA Ⅰ- Ⅱ patients aged 36-50 yrs, weighing 55-67 kg undergoing abdominal hysterectomy under combined spinal-epidural anesthesia were enrolled in this study. Spinal puncture was performed at L2-3 interspace. The patients received intrathecal 0.75% ropivacaine 2.0-2.6 ml. 2% lidocaine was used for epidural injection. The block height was maintained at T8-6 . For postoperative analgesia the patients were randomized to receive either intravenous morphine infusion at 10 ?g?kg-1 ?h-1 (group M, n = 21) or IV morphine infusion (10 ?g?kg-1?h-1)+ naloxone infusion at 50 ng?kg-1?h-1 (group MN, n = 21). Pain was assessed using VAS (0-10) with 0 representing no pain and 10 representing the worst possible pain. Blood samples were taken from peripheral vein before anesthesia (T0), at the end of surgery (T1) and at 6, 24, 48 h (T2,3,4) after operation for determination of plasma levels of ?-endorphin (?-EP), dynorphin A1-13 (Dyn) and leu-enkepholin (L-EK) .Results The patients were comparable with respect to, age, weight, occupation and duration of operation between the two groups. Two patients (1 patient in each group) were excluded from the study because of their refusal to have repeated blood samples taken. The analgesia was significantly better in group MN than that in group M in terms of VAS scores. Plasma level of ?-EP was significantly lower at 6 h after operation (T2 ) but significantly higher at 24 h postop. (T3 ) in group MN compared with that in group M ( P

Objective To investigate the calculi composition of patients with urinary calculi in Henan area and the clinical significance of preventing calculi recurrence with individualized method.Methods From August 2009 to July 2010,1050 patients in our hospital underwent extracorporeal shock wave lithotripsy (ESWL) and ureteroscopy and percutaneous nephrolithotomy were set as the experimental group,all stone specimens were detected with the BRUKER TENSOR27 infrared spectroscopy for analysis of stone composition,and nurse on duty gave instructions according to the stone composition to prevent recurrence.From July 2008 to July 2009 1010 patients in our hospital underwent extracorporeal shock wave lithotripsy,ureteroscope and percutaneous nephrolithotomy were set as the control group,patients in the control group were not given calculi component analysis and these patients received general prevention guidance.The calculi recurrence was compared between two groups.Results Among 1050 cases in the experimental group,urinary calculi with single component accounted for 46.29％,of which calcium oxalate stones accounted for 44.95％.Calculi with mixed components accounted for 53.71％,mainly were calcium oxalate and carbonate apatite mixture components (30.48％).57 cases (5.43％) occurred urinary stone recurrence in the experimental group,while 177 cases(17.52％) in the control group.The difference had statistical significance.Conclusions Urinary calculi analysis has important clinical significance for understanding the causes and treatment of calculi as well as prevention of recurrence of calculi.

BACKGROUND:Cartilage tissue engineering scaffold is a substitution for extracellular matrix, and there is a great significance on the shape and pore structure of the scaffold.
OBJECTIVE:To retrospectively focus on the fabrication technology of three-dimensional porous cartilage tissue engineering scaffolds.
METHODS:The first author searched PubMed, ELSEVIER SCIENCEDIRECT, Wanfang and CNKI databases (2000/2013) to retrieve relevant articles about the fabrication technology tissue-engineered cartilage scaffolds. The key words were“cartilage tissue engineering;scaffolds;fabrication”in English and Chinese, respectively. RESULTS AND CONCLUSION:The fabrication technologies of three-dimensional porous cartilage tissue
engineering scaffolds are as fol ows:Phase separation/freeze-drying, hydrogels, rapid prototyping manufacturing, electrospinning, solvent casting/particulate leaching, gas foaming. The current cartilage studies have demonstrated that the pore size has a significance on the regeneration of the cartilage tissue, the pore size ranging from 100-250μm al ows for the regeneration of bone and cartilage tissue. The scaffold fabricated by the solvent casting/particulate leaching and gas foaming technology at a pore size of 100-250μm is suitable for the bone and cartilage tissue regeneration. To obtain the adequate biological and mechanical properties, researchers usual y combine a variety of methods to fabricate the cartilage tissue engineering scaffolds.

Objective To study and develop the whole blood red cell lysing reagents in order to replace the commercial kit and reduce the cost.Methods Flow cytometry was used to compare the home-made red cell lysing reagents with the commercial kit on the separation of white cells into three groups,on the ratio of lymphocyte subsets and on the mean fluorescence intensity(MFI)of lymphocyte subsets.Results Compared with the commercial kit,the home-made lysing reagents had no significant difference on the separation of white cells into three groups,on the ratio of lymphocyte subsets and on the MFI of T lymphocytes,B lymphocytes,Helper-Inducer T-lymphocytes and Suppressor-Cytotoxic T-lymphocytes.Conclusions The home-made lysing reagents had similar effects as the commercial kit on the separation of white cells,on the ratio of lymphocyte subsets and on the MFI of T lymphocytes,B lymphocytes,Helper-Inducer T-Lymphocytes and Suppressor-Cytotoxic T-lymphocytes,but the cost is much lower.
