AIM To substantiate the therapeutic effects of carbonate buffer mixture on naturally occurring gastrointestinal atony in cattle. METHODS Therapeutic effects of carbonate buffer mixture (Na2CO3 50 g, NaHCO3 420 g, KCI 20 g, NaCI 100 g, water 10 L) were observed in 120 cases of gastrointestinal atony including forestomach atony, rumen impaction, rumen acidosis, omasum impaction and intestinal constipation. RESULTS Average cure rate of carbonate buffer mixture on abovementioned diseases was 95 %, and average dose was 1.4-0. 5. CONCLUSION Being a new approach for treatment of gastrointestinal atony in ruminants, the carbonate buffer mixture can eliminate the gastrointestinal atony originated from the over acidity in gastrointestinal canal.

Objective To study the relationship between parathyroid hormone(PTH)level and central arterial stiffness in patients with high risk of coronary artery disease(CAD) and preserved renal function.Methods Seventy-seven patients with at least one risk factor of coronary artery disease (CAD) were divided into increased arterial stiffness group(n=35) and control group(n=42),based on whether the noninvasive pulse wave analysis index of the central pulse pressure(CPP) was higher than 40mmHg or not.Coronary artery angiography was performed in all cases.Serum intact PTH,calcium,phosphor,and highly sensitive C reactive protein (hsCRP) was assessed by radioimmunoassay.Coronary angiography was also performed.Results The patients in increased arterial stiffness group were elder and had higher serum uric acid compared with those in the control group.Forty-four patients were confirmed to have CAD; CAD patients in the stiffness group (n=23) had significantly higher serum iPTH level compared with those in the control group(n=21) (P40 mmHg)after adjustment for age,BMI,hs-CRP,and male gender.Conclusion CAD patients with increased central arterial stiffness and preserved renal function have higher serum PTH level.The serum PTH level is positively correlated with central arterial stiffness,and is the independent risk factor for increased arterial stiffness.

BACKGROUND: Prospective studies concerning bone metabolism and bone mineral density variation after fractures have been reported from the 1960s, but these studies are mainly focused on tibia and fibula and ankle fractures in patients with low sample size.
OBJECTIVE:To observe the changes in bone mineral density and bone metabolism indexes in elderly women within 6 to 12 months after hip fractures, and to analyze the correlation.
METHODS:We selected 48 elderly women with hip fractures admitted in the Department of Orthopedics, Beijing Aerospace General Hospital in China from May 2011 to July 2013. Standards for fol ow-up were developed to measure the bone mineral density and bone metabolism indexes in the L 1-4 spinal segments and both sides of the hip. The bone metabolism indexes included bone alkaline phosphatase, osteocalcin, cross-linked C-terminal peptide of col agen I, and serum tartrate-resistant acid phosphatase 5b levels. Multiple linear regression analysis was performed based on measurements of bone mineral density and bone metabolism indexes after fracture healing.
RESULTS AND CONCLUSION:After fracture healing, bone mineral density of the fractured hip and lumbar vertebra was significantly lower than the baseline value. There was no statistical difference in bone mineral density between the healthy hip and the baseline value. At 6 months after fractures, bone alkaline phosphatase, osteocalcin, cross-linked C-terminal peptide of col agen I, and serum tartrate-resistant acid phosphatase 5b levels were significantly higher than the baseline values. At 12 months after fractures, osteocalcin level was significantly higher than the baseline value, while other indexes of bone metabolism measurements showed no statistical difference from the baseline values. When healing of hip fractures met the clinical and radiographic standards, the partial regression coefficient of delta-Z score reached peak in the changes of serum osteocalcin and bone mineral density of the fractured hip. Under clinical healing of fractures, serum osteocalcin level exhibits a higher value for the assessment of recovery speed of bone mineral density. Monitoring corresponding bone metabolism indexes after fracture healing can improve the accuracy of judging bone mineral density changes to reduce the risk of secondary fractures.

Objective To investigate the relationships between Cyclooxygenase(COX-2) and angiogenesis and expressions of COX-2 and vascular endothelial growth factor(VEGF) in thyroid cancer and its clinical significance.Methods Immunohistochemistry was used to detect the expressions of COX-2 and VEGF in 60 thyroid cancer,(15 thyroid)adenomas and 10 normal thyroid tissues.Results The expression rates of COX-2 and VEGF in thyroid cancer were higher than those in thyroid adenomas and normal tissues(P

In order to investigate the ability of PEG-PEI copolymers as gene carriers for delivery of VEGF165. A series of PEG-PEI copolymers with different PEG grafting was prepared and the cytotoxicity was evaluated. Simultaneously,the VEGF165 gene segment with HindⅢ and BamHⅠ site was obtained by PCR, which was cloned into pEGFP-C1. PEG-PEI/ pEGFP-VEGF165 complexes were formed by self-assembly and transfected HUVEc. Transfection efficiency was evaluated by measuring the percentage of cells expressing green fluorecensce protein. The VEGF expression was detected by ELISA, RT-PCR, and the effect of transfection on growth of endothelial cell was evaluated by MTT. The results suggested that the formation of PEG-PEI copolymers could help to reduce the cytotoxicity of PEI. After transfection, the strong expression of green fluorescence protein was observed by fluorescence microscopy. The transfection efficiency was influenced by the number of PEG side chains and N/P ratio. Of all copolymers tested, the transfection efficiency of PEG-PEI(5-25-1) at N/P = 30 reached a maximum, which was much higher than that of PEI. The expression of VEGF protein and mRNA increased significantly, and HUVEc proliferation was accelerated after transfection.These results indicates PEG-PEI copolymers can be used as effective gene carriers for delivery of pEGFP-VEGF165 gene.

Objective To explore the effects of comprehensive restraint reduction program on preventing un-planned extubation among ICU patients with tracheal intubation. Methods Totally 266 cases of ICU patients with tracheal intubation in our hospital were selected as the research objects using the convenient sampling method.They were divided into two groups by time: the experimental group of 130 cases implementing a comprehensive reduction constraint program and the control group of 136 cases using conventional physical restraint in nursing process.The constraint rate, constraint length, UEX incidence, skin and satisfaction of the two groups were compared. Results In the experimental group, the rate of physical restraint and UEX decreased, the average restraint length of each patient was shortened, skin integrity at the site of restraint improved, and the satisfaction of patients increased. Compared with the control group, the differences were statistically significant(P<0.01 or P<0.05). Conclusion The com-prehensive restraint reduction program can reduce the rate of physical restraint and the incidence of unplanned ex-tubation among ICU patients with tracheal intubation.
