Acupuncture has become a popular alternative modality in the treatment of back pain. However, few have reported complications related to this treatment modality. This study reports a rare case of septic arthritis of the lumbar facet joints, developing after acupuncture, and its devastating effects upon the patient. A 68-year-old female developed septic arthritis of the lumbar facet joints after acupuncture for symptomatic control of lumbar spondylosis and stenosis while waiting for surgery. Subsequently, successful control of the infection required a total of 4 hospital admissions over a 2-year period, a CT guided spinal biopsy and 6 months of antibiotics.

OBJECTIVE:To investigate the prognosis of coronary heart disease complicated with heart failure patients abandon-ing percutaneous coronary intervention (PCI) and receiving drug comprehensive therapy. METHODS:From Dec. 2010 to Jul. 2012,217 patients with coronary heart disease complicated with heart failure in our hospital were divided into operation group (105 cases) and non-operation group (112 cases). Based on routine treatment,operation group was given aspirin combined with clopidogrel before and after PCI,and non-operation group was given aspirin combined with clopidogrel all the time. The patients were followed up regularly during discharging from hospital to May 2015 by outpatient,telephone and coronary angiography re-checking,lasting for 24-38 months. Death cases,readmission and revascularization again caused by main adverse cardio-cerebrovas-cular events were recorded during follow-up period. RESULTS:7 cases and 8 cases in operation group and non-operation group did not accept follow-up;median follow-up time was 33 months and 32 months,respectively. Case number of myocardial infarction, heart failure and death in non-operation group was more than operation group,with statistical significance (P<0.05). 94 patients survived in operation group in 3 years,with survival rate of 95.9%;66 in non-operation group,with survival rate of 63.5%;with statistical significance(P<0.05). The survival time of non-operation group was shorter than that of operation group,with statistical significance(P<0.05). CONCLUSIONS:Although we still cannot get the conclusion that PCI is a better treatment or drug therapy is better. But the survival rate of patients are not optimistic 3 years after abandoning PCI coronary heart disease patients with severe myocardial ischemia should choose PCI firstly.

· AIM: To study the effects of topical anesthesia on corneal thickness in myopic eyes with Orbscan topography system and to assess the application prospect of this device in determining the corneal thickness for refractive surgery.and 5 minutes after administration of one drop of Benoxil (Oxybuprocaine) 4g/L solution (Santen, Japan) to 98 eyes (98 patients). The numeric value of the corneal thinness (THN) and the mean central corneal thickness (CCT) of 2mm in diameter were obtained before and after the instillation. The changes in anterior chamber depth (ACD) were also studied.P<0.001) and CCT by 3.10±7.13μm (t=-4.310, P<0.001) were found following the instillation of the topical anesthetic. There were no statistically significant changes in ACD (t=1.288, P=0.201).immediate effects on the corneal thickness in myopic eyes and this have implications for corneal refractive surgery and even for the accuracy of applanation tonometry.

OBJECTIVETo evaluate the feasibility and post-operation stability of extreme lateral transforaminal lumbar interbody fusion (E-TLIF) and other traditional surgical approach via bio-mechanical test.
METHODSThere were 24 normal lumbar spine segment of swine were divided into the following four groups: control group, standard group (internal fixed with pedicle screws only), transforaminal lumbar interbody fusion (TLIF) group and E-TLIF group. The specimen in anteflect, hypsokinesis, lateral flexion and rotate movements were tested respectively with bio-mechanical devices to study on the load-straining changes and biomechanics index.
RESULTSAfter TLIF or E-TLIF, specimen turned out more steady than normal control group (t = 4.17 - 4.53, P < 0.01). Compared with TLIF group [linear displacement (3.98 ± 0.22) mm, angular displacement 3.03° ± 0.18°], specimen after E-TLIF [linear displacement (3.40 ± 0.09) mm, angular displacement 2.57° ± 0.12°] were more stable in biomechanics index on lateral flection movement (t = 2.61, P < 0.05), but no difference on axial or rotational movements (P > 0.05).
CONCLUSIONE-TLIF is a safe and more efficient operation approach.

A 63-year-old gentleman presented with a one-year duration of progressive neurogenic claudication. However, unlike most patients who presents with leg symptoms, his pain was felt in his scrotal and perianal region. This was exacerbated with walking and standing, but he had immediate relief with sitting. An magnetic resonance imaging (MRI) was performed which showed severe central canal stenosis. An L3/4 and L4/5 surgical decompression and a transforaminal lumbar interbody fusion was performed, and the patient made good recovery with immediate resolution of symptoms. Although rare, spinal stenosis should be considered a differential when approaching a patient with perianal and scrotal claudication, even in the absence of leg claudication. An MRI is useful to confirm the diagnosis. This rare symptom may be a sign of severe cauda equina compression and we recommend decompression with predictable good results.
