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.

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.

AIM: To study the effectiveness of hyaluronidase periocular injection combined with α - lipoic acid and Chinese medicine in the treatment of diabetic vitreous hemorrhage.
METHODS: Retrospective analysis of 67 patientswith proliferative diabetic retinophathy ( PDR ) and vitreous hemorrhage, were divided into two groups: treatment group and control group. There were 32 cases in every group, the treatment group were giving hyaluronidase periocular injection combined with α - lipoic acid intravenously and with traditional Chinese medicine in promoting blood circulation to remove blood stasis, control group were only given Chinese medicine treatment in promoting blood circulation to remove blood stasis.
RESULTS: Followed up 2-3mo, the total efficiency of treatment group ( 78%) was better than control group (57%), there was statistically significant difference ( P<0-05 ) . The efficiency of the two groups' patients with vitreous hemorrhage more than 2wk time was 22% and 25% respectively, there was no statistically significant difference in the two groups (P>0. 05).
CONCLUSION: Hyaluronidase periocular injection combined with α-lipoic acid and Chinese medicine in the treatment of PDR combined with vitreous hemorrhageis more effective than only use Chinese medicine. But it only has effect for the early, over 2wk, it has no significant effect.

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.

AIM:To investigate the effect of fluvastatin on the expression of serum and glucocorticoid inducible kinase 1 ( SGK1) and connective tissue growth factor ( CTGF) induced by aldosterone ( Ald) in rat mesangial cells (GMCs). METHODS:GMCs were divided into (1) control group; (2) aldosterone group with different concentrations and times; (3) Ald (10 -7 mol/L) + spironolactone (10 -9 mol/L) group; (4) Ald (10 -7 mol/L) + LY294002 (20 ?mol/L) group; (5) Ald (10-7mol/L) +SB203580 (20 mmol/L) group; (6) the group of Ald (10-7mol/L) + fluvas-tatin at different concentrations (10-7,10-6,10-5 mol/L); (7) Ald (10 -7mol/L) + fluvastatin (10 -5mol/L) + mevalonate (10 -4 mol/L) group; (8) Ald (10 -7 mol/L) + fluvastatin (10 -5 mol/L) + FPP (farnesyl pyrophosphate,10-4 mol/L) group; (9) Ald (10 -7mol/L) + fluvastatin (10 -5 mol/L) + GGPP (geranylgerany pyrophosphate,10 -4 mol/L) group. The protein levels of SGK1 and CTGF were determined by Western blotting. The levels of fibronection (FN),monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1) in the supernatants were determined by enzymelinked immunosorbant assay (ELISA). RESULTS:Aldosterone stimulated the protein expression of SGK1 and CTGF in cultured mesangial cells in a dose-dependent manner (P

Objective To investigate the hearing and audiologic aspect of children who failed the universal newborn hearing screening.Methods A prospective analysis of 136 consecutive records of neonates referred to Chengdu women and children health hospital due to universal neonatal hearing screening failure. The diagnostic evaluation was performed at 3 and 6 months old and the protocol consisted of a standard otologic examination, diagnostic auditory brainstem response(ABR), transient evoked otoacoustic emissions (TEOAE), and middle ear assessment.Results In the initial 3 months old diagnosis, bilateral hearing loss was confirmed in 72 infants and unilateral hearing loss in 64 infants.Among 136 cases,mild hearing loss was found in 109,moderate in 9,severe in 7,and profound in 11 infants. In 6 months old confirmed diagnosis,permanent hearing loss was confirmed in 114 children with normal hearing in 22 infants. Bilateral hearing loss was diagnosed in 52 infants and unilateral hearing loss in 62 infants.Among these 114 cases,mild hearing loss was observed in 87,moderate in 11,severe in 4,and profound in 12.Conclusion The hearing level of the infants continues to change and those referred from hearing screening are in need of an in-depth evaluation and a comprehensive follow-up program.
