OBJECTIVETo explore the clinical effect of the sacrococcygeal space injection for the treatment of failed back surgery syndrome.

METHODSFrom July 1998 to October 2012,47 patients with failed back surgery syndrome were treated and included 39 males and 8 females with an average age of 61.5 years old ranging from 35 to 89 years old. Among them,41 patients experienced one time of operation, 6 patients with twice of operation. Forty-one patients underwent single,bilateral fenestration or central laminectomy decompression, discectomy. Six patients underwent total laminectomy discectomy and inter body fusion and pedicle screw fixation. All patients were examined by X-ray plain film, CT or MRI before treatment. The anticoagulation was discontinuation before treatment. The needle was put into the sacrococcygeal gap at prone position in the sense of frustration,suction without cerebrospinal fluid and blood,with injection of Mailuoning (Chinese characters: see text) 15 ml. The pain was assessed by VAS before and after treatment. The Oswestry low back pain disability index and survival quality interference degree were evaluated.

RESULTSAt 1 month after treatment,the pain VAS decreased from 59.24 +/- 17.35 before treatment to 19.19 +/- 11.19 after treatment (P < 0.05); The Oswestry low back pain disability index decreased from (41.35 +/- 9.87)% before treatment to (23.17 +/- 17.56)% after treatment (P < 0.05); The survival quality interference degree decreased from 6.5 +/- 2.2 before treatment to 2.6 +/- 1.4 after treatment (P < 0.05).

CONCLUSIONThe sacrococcygeal gap injection for treatment of failed back surgery syndrome has advantages of simple, safe, fewer complications, and low treatment cost.

The general characteristics, outcomes and risk factors of the patients with aortic dissection (AD) were evaluated in a single medical center. From January 2002 to December 2008, 284 patients with AD were treated and followed-up at our institution, including 105 cases of type A AD and 179 cases of type B AD. The patients in each type were divided into three groups according to management: medical treatment group (A or B), open surgery group (A or B), and stent-graft group (A or B). The characteristics and follow-up outcomes were compared between the groups or subgroups. The results showed that there was significant difference in the prognosis for type A AD between medical treatment group and open surgery group, but there was no significant difference in the prognosis for type B AD between medical treatment group and stent-graft group. Independent risk factors of follow-up mortality for patients with type A AD included a history of atherosclerosis (HR, 3.807; 95% confidence interval [CI], 1.489 to 7.611; P=0.003), in-hospital hypotension/shock (HR, 4.687; 95% CI, 1.846 to 11.900; P=0.001), in-hospital myocardial ischemia or infarction (HR, 3.734; 95% CI, 1.613 to 8.643; P=0.002), pleural effusion (HR, 2.210; 95% CI, 1.080 to 4.521; P=0.030), branch vessel involvement (HR, 2.747; 95% CI, 1.202 to 6.278; P=0.016) and surgical treatment (HR, 0.177; 95% CI, 0.063 to 0.502; P=0.001). And there were insignificant independent predictors for mortality of the patients with type B AD. It was concluded that there were significant differences in characteristics and one year mortality between type A AD and type B AD, but after one year, there was no significant difference in the mortality and complications of them. There were several discordant risk factors of AD, such as female gender, age, thrombus, abrupt onset of pain that were considered as the risk factors in some papers. And there was no definite risk factor of mortality in this study in the patients with type B AD.

Background Researches showed that as the non-optical factors,cognitive has certain influence on the regulating system.So accurately experimental design is one of the key steps that evaluates the non-optical factors on regulating system.Objective The present study was to investigate the influence of presenting pattern of target and watching way on the level and amplitude of accommodative fluctuate and to analyze the effect of focus gaze of cognitive on regulating system and the relationship between focus gaze condition under near work and the development of myopia.Methods This study complied with Declaration of Helsinki,and the permission of Ethic Committee and written informed consent was obtained before entering in this trial.Thirty healthy volunteers were included with the mean age (24.80 ± 1.98) years old,equivalent refractive diopter (-1.92 ± 2.02) D and mean cylinder (-0.19±0.58) D.The presenting pattern of the targets was designed as focus gaze and relaxed gaze.The accommodative response and accommodative fluctuation in the complete corrected right eyes for the different targets at the 40 cm under the gazing state was recorded with Grand Seiko WAM 5500 automatic infrared refractor in the experiment.Results The mean accommodative response value was (1.86±0.26) D under the focus gaze and (1.27±0.39) D under the relax gaze,showing a statistically significant difference (t=-8.052,P=0.000).The mean fluctuate value was(0.17±0.06) D under the focus gaze,with a significant lowing in comparison with (0.28±0.17) D under the relax gaze (t =3.600,P =0.001).Conclusions These results demonstrate that the different presenting patterns of sighting target and watching ways of the subjects affect accommodation system.The accommodative response was relatively more accurate with a smaller microwavc moving under the focus gaze condition.

Harmful substances are produced during the metabolism of alcohol in the human body, which causes liver disease.The mechanism of oxidative stress is the main pathogenesis of alcoholic liver disease, which plays a major role in the occurrence and development of alcoholic liver disease.Alcohol-induced oxidative stress mediated by reactive oxygen species(ROS)/reactive nitrogen species(RNS) brings about liver disease via apoptotic signaling pathway and MAPK signaling pathway, and alleviates liver disease through Nrf2 signaling pathway.In this paper, the studies on the mechanism of oxidative stress in alcoholic liver disease are reviewed.

Purpose To assess the feasibility of dual-energy dual-source virtual noncontrast (VNC) CT in the diagnosis of laryngeal carcinoma,in order to reduce radiation hazard.Materials and Methods Forty-nine patients with clinically identified laryngeal carcinoma underwent conventional non-contrast (CNC) scan as well as arterial and venous dual-phase and dual-energy VNC scan.The VCN images of arterial and venous phase were obtained by using the dual-energy software.The mean CT value,signal-to-noise ratio (SNR),contrast noise ratio (CNR),lesion morphology,image quality and radiation dose were compared between the VNC and CNC images.Results The mean CT value,SNR,CNR and image quality scores of CNC were higher than those of VNC images of arterial and venous phase (P＜0.05).There was no significant difference in the image quality scores of VNC between the arterial and venous phase (P＞0.05).The image quality scores of VNC were all above 3,which could meet the diagnostic requirements.There was no significant difference in the shape,size,boundary and cystic necrosis of the lesions,invasion of the surrounding space,osteolytic destruction and size of the surrounding lymph node between the CNC and VNC image.The radiation dose of dual-phase dual-energy scan was 0.42 mSv,which was 18.3％ lower than that of the conventional three-phase scan.Conclusion For laryngeal carcinoma,the VNC images from the dual-energy CT scan can be used to reduce the radiation dose without affecting image quality and diagnosis accuracy,which has good clinical value.

Objective To explore the electrophysiological charaterstics of upper extremities nerves on the patients with Hirayama disease (HD),amyotrophic lateral sclerosis (ALS),and distal cervical spondylotic amyotrophy (DCSA).Methods The data of electrophysiological examination of the upper limbs of 87 patients with HD,83 with ALS and 28 with DCSA were reviewed retrospectively.Seventy-two patients with HD among 87 had unilateral upper limb's amyotrophy and the other 15 ones had bilateral amyotrophy.There were 30 patients had unilater upper limb's amyotrophy and 53 ones had bilateral amyotrophy from the group of patients with ALS; 20 patients with DSCA were affected unilaterally and 8 ones were bilaterally affected.Results Compound muscle action potential (CMAP) evoked by ulnar stimulation had a lower ampititude compared with that evoked by median stimulation in HD patients.In ALS cases that was just the opposite.However,the CMAPs were similar in DCSA cases.The mean ratio of CMAP amplitude by ulnar stimulation to by median stimulation was 0.58±0.40 in HD group; 2.28±1.25 in ALS and 1.31±0.63 in DCSA.The differences in the three groups were statistical significance.The U/M CMAP ratio was less than 0.6in 62 patients with HD,3 with ALS and 1 with DCSA,and more than 1.7 in 73 cases (57 ALS,12 HD and 4 DCSA).Conduction velocities (CV) of the sensory and motor nerves,the amplitude of the sensory nerve action potential in bilateral limbs,and the CMAP amplitude of the unaffected limb were normal in all cases.Conclusion This study could concluded that the severity of amyotropy in hypothenar mucles were higher than that in thenal muscles in patients with HD; there was just opposite in ALS cases and similar in DSCA.

ObjectiveTo observe protective effects of agmatine (AGM) on inflammatory response and spleen immune function in mice with trauma.Methods Forty-eight adult male C57BL/6 mice were randomly divided into three groups (n= 16 each), including control group, model group (bilateral femoral fracture and removal of 35% of the total blood volume), and AGM group (trauma/hemorrhage & AGM 200 mg/kg). Eight mice in each group were sacrificed at 3 hours and 24 hours, respectively, after modeling, and blood samples and tissue homogenate of spleen and liver were collected. The contents of tumor necrosis factor-α (TNF-α), interleukins (IL-6, IL-1β) in serum and liver tissue were determined with enzyme linked immunosorbent assay (ELISA). Serum aspartate transaminase (AST), alanine aminotransferase (ALT) and lactic dehydrogenase (LDH) were determined with automatic biochemistry analyzer. Spleen proliferation response stimulated with concanavalin A (ConA) was evaluated with methyl thiazolyl tetrazolium colourimetry (MTT).γ-interferon (IFN-γ) and IL-2 releases were determined with ELISA.Results Compared with control group, 3 hours after trauma/hemorrhage, the levels of serum TNF-α, IL-6, and IL-1β in model group were significantly elevated [TNF-α (ng/L): 145.38±31.50 vs. 23.06±11.14, IL-6 (ng/L): 496.94±50.76 vs. 47.13±17.47, IL-1β (ng/L): 321.31±43.02 vs. 29.25±16.24,allP< 0.01]. It was found that AGM treatment could alleviate the increase in serum pro-inflammatory mediators induced by trauma/hemorrhage, such as TNF-α (ng/L:111.56±25.47 vs. 145.38±31.50), IL-6 (ng/L: 412.56±44.33 vs. 496.94±50.76), IL-1β (ng/L: 273.38±45.25 vs. 321.31±43.02,P< 0.05 orP< 0.01). Twenty-four hours after trauma/hemorrhage, serum pro-inflammatory mediators were recovered to the levels in control group. There was no significant difference in TNF-α and IL-6 levels at 3 hours after trauma/hemorrhage among groups. Compared with control group, the expressions of liver TNF-α and IL-6 in model group were increased at 24 hours following trauma [TNF-α (ng/mg): 32.93±4.90 vs. 26.58±2.33, IL-6 (ng/mg): 11.20±1.66 vs. 8.38±0.89,bothP< 0.01]. However, AGM inhibited the level of TNF-α (ng/mg:28.92±3.16 vs. 32.93±4.90) and IL-6 (ng/mg: 9.03±1.28 vs. 11.20±1.66) in the liver as induced by trauma/hemorrhage (P< 0.05 andP< 0.01). At 24 hours after modeling, model group and AGM group had distinctly higher serum AST, ALT, LDH levels than those of control group [AST (U/L): 405.9±31.2, 245.7±22.1 vs. 128.2±15.9; ALT (U/L): 92.1±6.3, 51.6±5.0 vs. 30.1±3.2; LDH (U/L): 606.7±36.3, 478.7±25.3 vs. 384.0±16.6, allP< 0.01]. Nevertheless,the increase in serum AST, ALT and LDH was alleviated in AGM group (allP< 0.01). Meantime, trauma/hemorrhage produced a noticeable depression of proliferation of splenic cells and IFN-γ and IL-2 release stimulated with ConA compared with control group [proliferation rate: (40.97±4.13)% vs. (89.99±7.76)%, IFN-γ(ng/L): 91.6±12.3 vs. 353.2±21.5,IL-2 (ng/L): 53.4±6.4 vs. 91.0±12.2,allP< 0.01]. In contrast, AGM notably restored the capacity of proliferation response of splenic cells [proliferation rate: (74.86±5.75)% vs. (40.97±4.13)%, P< 0.01],enhanced the release of IFN-γ and IL-2 stimulated with ConA [IFN-γ (ng/L): 327.8±23.6 vs. 91.6±12.3, IL-2 (ng/L): 74.8±10.4 vs. 53.4±6.4, bothP< 0.01].Conclusion AGM can dramatically alleviate spleen immunosuppression, excessive inflammation and organ damage induced by trauma/hemorrhage.

Three weeks’ training, visiting and demonstrating classes in Michigan State University gave us an opportunity to understand the education system, the teaching characteristics and the “students centered”teaching principle of USA. Some reasonable teaching methods were applied in the class which may embody the student-oriented teaching aim and develop the students’ subjective initiative. The teaching effect showed that most students were fond of the teaching strategies and they also did good job in final tests.
