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.

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 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 observe any influence of hyperbaric oxygen (HBO) treatment on the formation of glial scars,and to explore how HBO suppresses the inflammatory reaction to injury.Methods A total of 96 healthy,adult,male,Sprague-Dawley rats were used to model cerebral puncture injury.They were then randomized into a control group and a treatment group,with 48 rats in each group.The treatment group received HBO treatment,while the control group received no special treatment.At 1,3,7,14 and 28 days after the puncture injury,the rats' right brain tissues were harvested and immunohistochemical staining was employed to compare the changes in number of astrocytes and microglial cells around the injury in the two groups.The level of tumor necrosis factor α (TNF-α) and interleukin 1 β (IL-1β) in the cerebral tissue was examined using ELISA.Results Among the control group the average wound areas after 7,14 and 28 days were (2.73 ± 0.05)μm2,(3.42 ± 0.18)μm2 and (2.41 ± 0.09) μm2,a significant reduction after 28 days compared with 7 and 14 days.The corresponding average wound areas of rats in the treatment group were (2.78±0.12)μm2,(2.59 ±0.08)μm2 and (1.20 ±0.06)μm2.There the average wound area had decreased significantly after 14 days,and the further reduction after 28 days was also significant.The numbers of GFAP-positive astrocytes at 14 and 28 days had increased significantly compared with after 7 days in both the control group and the treatment group.The average number of GFAP-positive astrocytes in the control group at 28 days had decreased significantly compared with after 14 days.Compared with the control group at the same time points,the number of GFAP-positivc astrocytes in the treatment group was significantly less.After modeling,the number of ionized calcium-binding adapter molecule Ⅰ (Ibal)-positive microglial cells increased significantly,but there was a significant decrease in both the control and treatment groups by 7 days.The average number of Ibal-positive microglial cells in the treatment group was significantly less than in the control group at all of the time points.Compared with the first day after modeling,the TNF-α concentration of the controls at 3 and 7 days was significantly higher,but by the 7th day it was significantly lower than it had been after 3 days.The average IL-1β concentration in the control group and TNF-α concentration in the treatment group had increased by day 3,but then decreased by day 7.The IL-1β concentration of the treatment group declined gradually.The average TNF-α and IL-1 β concentrations of the treatment group were significantly lower than those of the control group at all of the time points.Conclusion HBO treatment has a relatively good curative effect on cerebral puncture injury.It can accelerate wound healing and reduce the formation of glial scars.Its mechanism could be related to the deactivation of astrocytes and microglia cells and reducing the levels of cell factors that promote inflammation.

Objective To investigate the effect of recombinant human growth hormone (rhGH) action on pregnancy rate of polycystic ovarian syndrome(PCOS).Methods The PCOS who were client in our hospital in February-August,2012 were investigated.The rhGH group (41 cases) were that all patients took rhGH at the same time ovulation.The control group (41 cases) were no medication group.The two groups had sex action after ovulation.Ovulation rate,pregnancy rate and endometrial score of the two groups were compared.Results Ovulation rate of rhGH group was 90.2％ (37/41),the control group was 68.2％ (28/41),the difference was statistically significant (x2 =3.459,P =0.036).Clinical pregnancy rate of RhGH group was 32.7％ (12/37),the control group was 25.0％ (7/28).The difference was statistics significance (x2 =4.319,P =0.032).Endometrial score of rhGH group was (14.96 ± 2.18),the control group was (12.77 ± 2.60) points,the difference between groups was statistically significant (t =-3.356,P =0.032).Conclusion Giving rhGH ovulation cycle specification can promote ovulation PCOS patients and improve the adverse factors affecting pregnancy,improving the pregnancy rate.
