Objective To observe the impact of hyperbaric oxygen (HBO) therapy on blood pressure and heart rate in adults with spinal cord injury (SCI). Methods 48 adult SCI patients who accepted HBO therapy from March to November, 2014, were observed. Other 48 non-SCI patients matched sexes and ages were as the controls. Their blood pressure and heart rate were measured before chambering, before compression, HBO for 30 minutes, before decompression and at the end of decompression. The patients were divided into high SCI group and low SCI group based on the injury levels above or below T4. Results The blood pressure was lower in the high SCI patients than their controls (t>6.337, P<0.001), and increased as taking in the oxygen. There was no significant difference between the high SCI patients than their controls as they took in for 30 minutes and before the decompression (P>0.05). No difference was found between both groups in heart rate (P>0.05). For the low SCI patients, neither the blood pressure nor the heart rate was different from their controls (P>0.05). Conclusion The blood pressure may increase during HBO intaking in the high SCI patients, which need be paid attention to.

Objective:To observe the effect of two different apical surgery timing. Methods:68 patients with periapical lesion were divided into 2 groups. 30 patients( control group) were operated by apical surgery at least 1-2 months after root canal therapy( RCT) , while 38 patients(experimental group) were operated immediately after RCT. The patients were followed up 3, 6 and 12 months after apical surgery. Results:The curative effect analysed with the age, sex and tooth position showed no statistical difference between 2 groups(P>0. 05). Conclusion:Immediate and delayed apical surgery apical surger after RCT are similarly effective.

ObjectiveTo analyze the characters of POEMS syndrome, raise physician awareness of diagnosis and therapy,and explore the optimal treatment strategies.MethodsThe clinical features,laboratory examination and therapy of 24 patients with POEMS syndrome were analyzed,and relative literatures were reviewed. ResultsA strong predominance of male over female was found, 18 vs 6. All patients were over 40 years old,with a mean age 56.5 years old,indicating a common adult involvement.All presented with polyneuropathy,which was also the most common complaints when admitted,which reminded neurologists of underlying possibility of a rare plasma cell disorder.Organomegaly was found,including 19 cases with hepatomegaly,17 patients with splenomegaly.Endocrinal abnormalities were also found in 15 cases.18 patients were M protein positive. Skin pigmentation was recognized in 21 cases. Melphalan in combination with prednisone was applied and 100 ％ response was observed. One of the patients received peripheral blood stem cell transplantation(PBSCT)2 years ago and a durable response was observed with a continuous complete remission of polyneuropathy and the absence of M protein following 2 years post PBSCT.ConclusionPOEMS syndrome is a rare multisystem disorder, the combination of symptoms and signs is highly complex,which is easy to misdiagnose or missed diagnose.A polyneuropathy with either organomegaly,endocrinal abnormalities, skin disorder or serositis is required a further investigation of clonal M protein and bone marrow.Melphalan and prednisone probable are the optimal regimens.PBSCT provides a new choice for therapy and research of POEMS syndrome.

This study aims to establish a method to determine the serum acetaminophen concentration based on diazo reaction, and apply it in the gastric emptying evaluation. Theoretically, acetaminophen could take hydrolysis reaction in hydrochloric acid solution to produce p-aminophenol, which could then take diazo reaction resulting in a product with special absorption peak at 312 nm. Then the serum acetaminophen concentration and recovery rate were calculated according to the standard curve drawn with absorbance at 312 nm. ICR mice were given a dose of acetaminophen (500 mg x kg(-1)) by gavage and the serum acetaminophen was dynamically measured through the diazo reaction. Besides, ICR mice were subcutaneously injected with the long-acting GLP-1 analog GW002 before the gavage of acetaminophen, and serum acetaminophen concentration was measured as above to study how GW002 could influence the gastric emptying. The data showed acetaminophen ranging from 0 to 160 μg x mL(-1) could take diazo reaction with excellent linear relationship, and the regression equation was y = 0.0181 x +0.0104, R2 = 0.9997. The serum acetaminophen was also measured with good linear relationship (y = 0.0045 x + 0.0462, R = 0.9982) and the recovery rate was 97.4%-116.7%. The serum concentration of acetaminophen reached peak at about 0.5 h after gavage, and then gradually decreased. GW002 could significantly lower the serum acetaminophen concentration and make the area under the concentration-time curve (AUC) decrease by 28.4%. In conclusion, a method for the determination of serum acetaminophen based on the diazo reaction was established with good accuracy and could be used in the evaluation of gastric emptying.

Objective To explore application effect of evidence-based nursing in operation of rupture of liver and apleen. Methods 108 patients with rupture of liver and spleen received evidence-based nursing during perioperative period, that is, to determinate nursing problems needed to prove, retrieve and analyze related articles, make the best nursing mode and prevent complications. Results Complications appeared in 15 patients, intra-abdominal hemorrhage in 4 patients, infection in 7 patients and splenic fever in 4 patients. All were corrected in time, and no case showed thrombosis and organ failure. Conclusions EBN can prevent post-operative complications for patients with rapture of liver and spleen and improve nursing quality.
