Objective To observe the effect of applying nourishing kidney and ventilating lung combined with western medicine in treating cough variant asthma (CVA) patients with kidney yang deficiency. Method Eighty CVA patients with kidney yang deficiency were divided into contrast group and therapeutic group, each group with 40 patients. The patients in contrast group were treated with Aminophylline sustained-release tablet, 0.1～0.2 g, 2 times a day, as well as Ketotifen tablet, 1 mg, 1 time a day, p.o. As for the therapeutic group, the patients were treated with Chinese herbs of nourishing kidney and ventilating lung based on the treatment of contrast group. One course was 4 weeks for the two groups, and the evaluation were carried out in the fifth week. Results After the treatment, CD8+ ascended significantly, and CD4+ and IgE descended significantly compared with the pre-treatment. There were significant differences between two groups (P

Objective To investigate the effect of irrigation with hypothermic artificial cerebral-spinal fluid (aCSF)on expression of aquaporin-4(AQP-4) in the spinal cord following spinal ischemia-reperfusion (I/R) in rabbits.Methods Fifty-four adult male New Zealand white rabbits weighing 2.0-2.5 kg were randomly divided into 3 groups (n=18 each):group sham operation(S group); group I/R and group irrigation with hypothermic aCSF (FI group). Spinal I/R was induced by clamping the abdominal aorta below renal artery for 60 min. Hypothermic aCSF(25 X.)was infused at L4,5 interspace at a rate of 30 ml/h and drained from L7,8 interspace during spinal ischemia.Neurological function was evaluated at 4, 24, 48 and 72 h of reperfusion and scored (0=no hind limb activity, 4=hind limb function completely recovered) in 6 animals in each group. Six animals were sacrificed at 4, 24 and 72 h respectively in each group.The lumbar segment (L5-8) was removed for measurement of water content and AQP-4 protein expression (by immuno-histochemistry).Results Neurological function scores were significantly lower,water content was higher and AQP-4 expression smaller in group I/R than in group S. I/R-induced effects were significantly attenuated by irrigation of hypothermic aCSF. Conclusion Irrigation with hypothermic aCSF can ameliorate the spinal cord I/R injuries by up-regulation of AQP-4 expression.

Objective To investigate the postmortem redistrib ution of morphine in rat model of chronic morphine poisoning. Methods Samples including cardiac blood, liver, heart, kidney, lung and brain tissues were collected in the rats with chronic morphine poisoning at 0～96 h after death, respectively. The morphine amount was measured with solid phase ext raction-gas chromatography. Results The study showed an increase in morphine concentrat ion of postmortem cardiac blood. Significant increase in morphine level was also observed 24～96 h after death in liver, heart and brain tissues, while the kid ney morphine levels decreased at 96 h after death. In the liver there was the g reatest increase (25-fold) in morphine levels 96 h after death. All the sample s showed marked alterations in morphine concentration within 96 h after death c ompared with cardiac blood at time of death. The postmortem morphine levels in b rain were closely related to those in the heart blood. Conclusion The postmortem redistribution of morphine exists in rats with chronic morphine poisoning. The brain tissues may better represent morphine levels in heart blood at the time of death.

Objective To analyze the concentration changes of insulin and c peptide of in portal vein and peripheral blood, and explore the feasibility of using insulin and c peptide concentration changes in assessment of liver function. Methods The portal vein and peripheral blood samples were extracted from 82 clinical liver cancer patients, and the insulin and c peptide concentration were detected. The differences in the insulin and c peptide concentration in portal vein and peripheral blood were statistically analyzed. Results The insulin concentration in the portal vein and peripheral blood values were 32.43 μ U/ml and 8.05 μ U/ml, respectively, there was a significant difference (P<0.05) . The c-peptide concentration in the portal vein and peripheral blood values were 1.38 μU/mL and 1.19 μg U/mL, respectively, there was no significant differences (P>0.05) . Conclusion Liver metabolizes insulin as the target organ of insulin, while c-peptide dose not be metabolized in vivo, so it is possible to assess liver function by comparative analysis of the metabolic rate of insulin and c-peptide changes.

Objective To investigate the value of the combined test in the diagnosis of thalassemia and iron deficiency anemia (IDA) .Methods From August 2013 to February 2015 ,36 patients with thalassemia ,34 patients with IDA ,and 30 healthy people who had undergone physical examination were enrolled in the study .The blood samples of those people were tested ,and items of the combined test included content of red blood cell volume(MCA) ,red blood cell volume distribution width(RDW) ,hemoglobin(Hb) electrophoresis and red blood cell(RBC) .Results The patients with IDA or thalassemia had reduced MCA and RBC fragile ,pa‐tients with IDA had increased RDW ,and patients with thalassemia had increased HbA2 ,compared with the control group the differ‐ences were all statistically significant(P<0 .05) .The sensitivity of RDW to IDA was 70 .6% ,and to thalassemia was 77 .8% ,the difference was not statistically significant (P> 0 .05) .The sensitivities of MCV ,Hb electrophoresis ,RBC fragility to thalassemia were 97 .2% ,88 .9% ,77 .8% respectively ,and the specificity were 80 .0% ,90 .0% ,83 .3% respectively .The sensitivities of MCA test combined with Hb electrophoresis ,hemoglobin electrophoresis combined with RBC brittleness test and parallel combined test of MCA ,Hb electrophoresis and RBC brittleness to thalassemia were 100 .0% ,97 .2% ,100 .0% respectively ,which were significantly higher than those of single tests ;the specificities were 96 .7% ,100 .0% and 100 .0% respectively ,which were significantly higher than those of single tests ;the differences were statistically significant(P<0 .05) .Conclusion The application of hematological pa‐rameters ,Hb and RBC in the diagnosis of anemia and IDA could significantly improve the diagnostic accuracy ,and it is worthy of popularization and application .
