Background Glucocorticoid is a common drug for treatment of thyroid-associated ophthalmopathy (TAO) with good effectiveness.But some adverse reactions of glucocorticoid are inevitable.At recent years,99technetium-methylene bisphosphonate(99Tc-MDP) is being paid more and more attentions in the treatment of TAO,but its effectiveness and safety is worthy of comparison to traditional treatment methods.Objective This study was to evaluate the efficacy of treatment with intravenous injection of 99Tc-MDP for TAO.Methods The Cochrane Library,CNKI,PubMed,Wanfang database,Weipu net were searched in computer and Google Scholar was searched manually.The randomized controlled trail (RCT) of intravenous injection of 99Tc-MDP for TAO were collected from establishment of database through April,2012.The quality of included literature was assessed based on the methodology of the study.The evaluating indexes included the primary treating outcomes,such as total efficacy,exophthalmic extent and recurrence rate as well as secondary outcomes such as adverse effect.RevMan 5.1 software was used for Mate analysis.Results A total of 11 RCTs were identified with 706 patients.Subgroup analysis was carried out based on the outcome measures and intervention.No significant difference was found in the overall effective rate between intravenous injection of 99Tc-MDP and immunosuppressive treatment (RR =0.96,95 ％ CI:0.76 to 1.22,P=0.740).However,the effective rate was significant different between intravenous injection of 99Tc-MDP and oral prednisone (RR =1.25,95 ％ CI:1.06-1.46,P =0.007) or between intravenous injection of 99 Tc-M DP and the blank control group (RR =2.53,95 ％ CI:1.68-3.81,P =0.000).Significant difference also was found in the total effective rate between intravenous injection of 99Tc-MDP with methyprednisone and methyprednisone alone (RR =1.27,95％ CI:1.05-1.53,P =0.010).There were significant differences in the effective rate of proptosis between intravenous injection of 99Tc-MDP and oral prednisone (RR=2.02,95％ CI:1.44-3.56,P=0.020).The recurrence rate of TAO was significant different between intravenous injection of 99Tc-MDP and oral prednisone (RR =0.51,95％ CI:0.33-0.78,P=0.002).Less adverse responses were seen in the intravenous injection of 99Tc-MDP group than the oral prednisone group and immunosuppressive treatment group.Conclusions Intravenous injection of 99Tc-MDP for TAO appears to be of a similar effectiveness to immunosuppressive method.The combination of intravenous injection of 99Tc-MDP with methyprednisone seems to be more effective than methyprednisone alone,with little systemic adverse effect after application.

This study was aimed to improve the sensitivity of magnetic induction phase shift detection system for cerebral hemorrhage. In the study, a cerebral hemorrhage model with 13 rabbits was established by injection of autologous blood and the cerebral hemorrhage was detected by utilizing magnetic induction phase shift spectroscopy (MIPSS) detection method under the feature band. Sixty five groups of phase shift spectroscopy data were obtained. According to the characteristics of cerebral hemorrhage phase shift spectroscopy under the feature hand, an effective method, B-F distribution, to diagnose the severity of cerebral hemorrhage was designed. The results showed that using MIPSS detection method under feature band, the phase shift obviously growed with increase of injection volume of autologous blood, and the phase shift induced by a 3-mL injection reached -7.750 3 degrees ± 1.420 4 degrees. B-F distribution could effectively diagnose the severity of cerebral hemorrhage. It can be concluded that the sensitivity of the cerebral hemorrhage magnetic induction detection system is improved by one order of magnitude with the MIPSS detection method under the feature band.

AIM:To evaluate the efficacy of half-dose verteporfin photodynamic therapy for central serous chorioretinophathy (CSC) in patients aged above 45 years old.METHODS:Thirty-two eyes of 30 patients aged above 45 years old with central serous chorioretinophathy were included,and all the eyes received half-dose verteporfin photodynamic therapy (PDT).Best-corrected visual acuity (BCVA),central macular thickness (CMT) and subretinal fluids absorption (SRF) were measured before and after treatment (1,3 and 6mo).RESULTS:The rate of SRF absorbing completely was 44％ at 1mo,63％ at 3mo and 75％ at 6mo.The difference in cure rate of the three time points was statistically significant (x2 =6.621,P=0.037).All the patients were divided into two groups according to the duration,patients in Group A were treated less than 6mo,Group B were ≥6mo.The mean LogMAR BCVA in the two groups were respectively 0.6149±0.4117 and 0.8167±0.4370 before treatment and the mean CMT were 409.47±129.422μ m and 395.82 ± 153.756μm before treatment.The difference between the two groups in the LogMAR BCVA was not statistically significant (F=0.303,P=0.823),but the time difference within the subjects was statistically significant (F=32.837,P＜ 0.001).In Group A,the differences of the LogMAR BCVA at pre-treatment,1 mo and 3mo was all statistically significant (P＜ 0.05),but the differences of the LogMAR BCVA at 3mo and 6mo was not statistically significant (t =2.024,P =0.063).In Group B,the differences of the LogMAR BCVA at any two time points were all statistically significant (P＜ 0.05).The difference between the two groups in the CMT was not statistically significant (F=0.064,P=0.978),but the time difference within the subjects was statistically significant (F=26.447,P＜0.001).In Group A,the differences of the CMT at any two time points were all statistically significant (P＜0.05).So were in Group B (P＜0.05).CONCLUSION:Half-dose verteporfin PDT was effective in treating CSC aged above 45 years old,it still could improve BCVA and subretinal fluids absorption.

OBJECTIVETo explore the association of fractalkine (FKN) and CD11c expressions oncommon carotid artery atherosclerotic plaques from apoE(-/-) mice with the severity of atherosclerotic lesions.

METHODSTotally 24 apoE(-/-) mice were divided into two groups and fed on a high-fat diet or a normal diet for 12 weeks. Then the blood lipids as well as the plaque area and vascular stenosis rate of the common carotid artery were measured to evaluate the severity of atherosclerotic lesions of the animals. Moreover, immunohistochemical staining was performed to examine the levels of FKN and CD11c expression.

RESULTSThe plaque areas and vascular stenosis rates of the common carotid artery in the experimental group were remarkably larger than those in control group (about 4-fold and 2-fold, respectively). The level of FKN expression in the experimental group was 2 times of that in the control group (P<0.05), and the number of CD11c (+) cells in the plaques in the experimental group was about 4 times of than in the control group (P<0.05).

CONCLUSIONThe expressions of chemokine and FKN remarkably increase in apoE (-/-) atherosclerotic plaques, suggesting that chemokine and FKN may paly important roles in the development of atherosclerosis.

Objective To evaluate interventional therapy for biliary stricture (BS) after orthotopic liver transplantation (OLT). Methods The efficacy of interventional therapy for BS after OLT from Oct 2003 to Jan 2006 was analyzed retrospectively. Fifty-three patients received 107 times of interventional therapy through endoscopic retrograde cholangiography ( ERC) which included 68 nasobiliary catheter placements,26 biliary balloon dilatations and stent placements and 13 ERC. Nine patients received 11 times of interventional therapy through percutaneous transhepatic cholangiography ( PTC) including 2 PTC, 7 percutaneous drainages,3 biliary balloon dilatations and 1 biliary stent replacement. One patient received bile drainage through T tube. Results The success rate of ERC was 88. 8% (95/107) , that of nasobiliary catheter placement 94% (64/68) , biliary stent placement 88. 5% (23/26). The success rate of PTC was 81. 8% (9/11) , that of percutaneous drainage was 100% (7/7) , biliary stent replacement 100% (1/1). The curative rate of interventional therapy for 53 patients with BS was 28. 3% (15/53) ,the improvement rate was 41. 5% (22/53). The curative rate of interventional therapy for anastomotic, extrahepatic, intrahepatic hilar and diffuse BS was respectively 66. 7% (4/6)、66. 7% (10/15)、50% (1/2)、0 (0/7) and 0 (0/22). Conclusions The efficacy of interventional therapy for BS after OLT was not satisfactory. The result relates to the type of BS, for anastomotic, extrahepatic and solitary intrahepatic BS this therapy was effective, while that for hilar and diffuse BS the prognosis was poor.

OBJECTIVETo explore the treatment and appropriate management of invasive aspergillosis infection following orthotopic liver transplantation.

METHODSThe clinical data of 576 cases who underwent orthotopic liver transplantation consecutively between January 2000 and January 2005 were analyzed retrospectively.

RESULTSThe prevalence of invasive aspergillosis infection was 1.74 (9/576), included 8 cases with pulmonary aspergillosis and 1 case with cerebral aspergillosis. The interval between transplantation and diagnosis were from 10 days to 2 months. Persistent or discontinuous low fever maybe the main clinical presentation after operation. Liposomal amphotericin B (AmBisome) is the mainly treatment for invasive aspergillosis infections, 5 patients were cured and 2 patients developed multi-organ aspergillosis infection died.

CONCLUSIONSThe clinical features of invasive aspergillosis infection following orthotopic liver transplantation were un-typical presentations in the early stage and easy to disseminate. Appropriate modification of immunosuppression therapy and early, high dose and long-term application of antifungal treatment is effective and safe to cure the disease.

OBJECTIVETo explore the effect of acupuncture-drug compound anesthesia on immune function in patients with extracorporeal circulation undergoing cardiac surgery.

METHODSThirty cases undergoing cardiac surgery which included atrial septal defect neoplasty, ventricular septal defect neoplasty, mitral valve replacement and pulmonary valve coarctotomy were randomly divided into group A and group B, 15 cases in each group. Group A was given general anesthesia plus acupuncture at Neiguan (PC 6), Lieque (LU 7) and Yunmen (LU 2), and group B was given simple general anesthesia. Tumor necrosis factor-alpha (TNF-alpha), interleukin-2 (IL-2) and interleukin-10 (IL-10) levels before and after surgery were compared.

RESULTSThe level of TNF-alpha was increased and the levels of IL-2 and IL-10 in the serum were decreased in both groups after extracorporeal circulation for 2 h and 24 h, and the ranges of all changes were more less in group A (all P < 0.05).

CONCLUSIONCompared with simple general anesthesia, acupuncture-drug compound anesthesia can improve immune suppression partially in the perioperative periods under the same conditions of controlling anesthesia degree.

OBJECTIVETo study the clinical features, underlying mechanism and management of major neurological complications following liver transplantation.

METHODSThe data of 467 patients undergoing liver transplantation from Oct. 2003 to Sep. 2005 were retrospectively reviewed.

RESULTSNeurological complications occurred in 91 (19.49%) cases. The most common neurological complications were encephalopathy (72 cases), followed by stroke (12 cases), seizure (4 cases), central pontine myelinolysis (3 cases), and central nervous system infections (2 cases). Five encephalopathy cases were treated with continuous renal replacement and 5 intracranial hemorrhage cases with neurosurgical intervention. The mortality related to neurological complications was 10.98% (12/91).

CONCLUSIONSNeurological complications are common and potentially fatal following liver transplantation involving several factors. CsA and FK506 may play an important role in the onset of neurological complications, and stroke, especially intracranial hemorrhage, has a high mortality. Combined therapies and timely modulation of the immunosuppressive regimens may improve the patient's outcome.
