The purpose of this clinical study was to evaluate the protective effect of continuous potassic warm blood perfusion on myocardium during warm blood extraeorporeal circalation. Warm blood cardiopulmonary bypass and continuous potassic warm blood perfusion for myocardial protection were used in 39 cases undergoing coronary bypass. 15% potassium chloride was mixed with oxygenated warm blood for continuous myocardial perfusion to induce cardiac arrest. The average nasopharyngeal temperature was maintained at 33.5℃. The warm blood was delivered at a rate of 150 to 200 ml/min; 15% potassium chloride was pumped at a high flow rate of 120 to 160 ml/h and then at a low flow rate of 15 to 20ml/h when electrocardiogram showed straight line. The results showed that 38 cases (97.4%) had spontaneous return of normal sinus rhythm shortly after removal of the aortic crossclamp. Myocardial positive inotropic agents were seldom used and hemodynamics kept stable. Cardiac functions showed fast recovery and there were not serious complications such as perioperative myocardial infarction, low output syndrome and arrhythmia. It is indicated that continuous potassic warm blood perfusion for myocardial protection may have a remarkable results to prevent myocardial anoxemia and reperfusion injury during CPB.

Objective To explore the effect of appreciation intervention on anxiety and complications in patients with renal biopsy. Methods A total of 197 cases of renal biopsy patients were divided into the control group (n=96) and the observation group (n=101). The observation group was given comprehensive nursing intervention with appreciation, the control group was only given comprehensive nursing care, the two groups were evaluated with Zung Self-rating Anxiety Scale (SAS) upon admission and 1 week after puncture. Results After intervention, the SAS score of the observation group was 30.87 ± 4.52, and the SAS score of the control group was 32.32 ± 3.72, and the difference between the two groups was statistically significant (t=2.45,P<0.05). Totally 97 patients in the observation group and 78 cases in the control group received bed urination exercises, and the difference between the two groups was statistically significant (χ2=9.412,P<0.01). The complications of two groups were collected, the complications in the observation group were 27 cases, and the complications in the control group were 50 cases, the difference between the two groups was statistically significant (χ2=13.285,P<0.01). Among the postoperative complications, 8 of the patients in the observation group had urinary retention, and 19 of the control group had urinary retention (t=2.446,P=0.015). In the observation group, 3 cases had abdominal distention, and 10 cases in the control group suffered from abdominal distension (t=2.117, P=0.035). In the observation group, 1 case had low back pain, and 6 cases in the control group suffered from lumbago (t=2.004, P=0.047); the difference was statistically significant. Conclusions Appreciate intervention for patients with renal puncture biopsy has a positive impact on the bed urination exercise in puncture before surgery. It can alleviate the anxiety of patients received renal biopsy, reduce urinary retention, abdominal distension and pain complications, and improve bedridden experience.

One hundred and eighty two outpatients with functional dyspepsia (FD)were enrolled.The cognitive questionnaire and the short form Nepean Dyspepsia Index (NDI) were used for survey.Spearman analysis showed that the cognitions of symptoms affected by emotion (r =0.284,P =0.006),somatisation symptoms induced by other diseases (r =0.211,P =0.045),and fears of cancer (r =0.217,P =0.039) were positively correlated with NDI scores.Multiple linear regression analysis demonstrated that cognition of symptoms affected by emotion (β =3.709,P =0.009),somatisation symptoms induced by other diseases (β =3.259,P =0.020),need of hospitalization (β =4.533,P =0.006),and need of medication for several years (fβ =-3.207,P =0.029) were associated with NDI scores.These results suggest that the quality of life might be effected by cognitive factors,and the correction of cognitive mistakes may improve quality of life of FD patients.

Objective To evaluate the double-balloon enteroscopy(DBE) for obscure gastrointestinal bleeding(OGIB) and evaluate the health economics under the guidance of DBE for surgical treatment of obscure gastrointestinal bleeding.Methods A total of 114 patients,whose hemorrhage etiology could not be determined by conventional gastroscopy,enteroscopy and gastroenterography,underwent DBE.With pathological results as diagnostic criteria,the value of double-balloon enteroscopy for obscure gastrointestinal bleeding diagnosis was studied.Results The sensitivity,specificity and accuracy of DBE for OGIB were 85.86％,63.63％,81.57％,respectively.The positive likelihood ratio was 2.36 and the negative likelihood ratio was 0.22.The total days of hospitalization,hospital costs,cost of hospital drugs were lower in the DBE group than in the control group(27.2 ± 11.8 days VS 16.4 ±5.3 days,35 690.2 ±3 466.5 Yuan VS 19 409.3 ± 9 253.2 Yuan,17 805.8 ± 2 145.5 Yuan VS 9 133.0 ± 4 664.9 Yuan) (all P ＜ 0.05).Conclusion DBE plays an important role in diagnosis of OGIB.It has significance in clinic,health economics,and social benefits.

Objective To establish blood screening and genetic detection of thalassemia trait in pregnant couples in Chang‐shou area so as to provide guidance for aristogenesis and prenatal diagnosis .Methods A total of 1 760 pregnancy in maternal and child health hospital treated from January 2013 to October 2014 were selected for study .The component of hemoglobin was ana‐lyzed as primary screening and genotype of pregnant couples were ensured in which primary screening result is positive .Results There were 27 cases suspected as α‐thalassemia (positive rate was 1 .53% ) and 25 cases suspected as β‐thalassemia(positive rate was 1 .42% ) in the primary screening(n=1 760) .The positive rate of gene carrier were 31 .51% (n=438) in women and 33 .33%(n=27) in men .Conclusion The routine screening of thalassemia could guide aristogenesis in high incidence area and provide terms of prenatal diagnosis and genetic counseling .

OBJECTIVE： To study the pharmacokinetics and relative bioavalability of omeprazole capsules in humans.METHODS： 18 male healthy volunteers orally took domestic omeprazole capsules and losec capsulles(used as control)40mg respectively.Blood concentrations of drugs were determined by HPLC.RESULTS： Times to reach the peak levels of omeprazole and losec were （2.10± 0.64） h and （1.88± 0.70） h， the peak plasma concentrations were （895.64± 553.07） ng/ml and （974.67± 554.93） ng/ml and the areas under the drug concentration curves were （1 971.88± 1 220.98 ） ng/（h· ml） and （2 057.60± 1 306.32） ng/（h· ml） respectively.CONCLUSION： The two capsules have the same bioequivalence.
