OBJECTIVE: Through 3.0 T MRI study the ear and sinus lesions of patients with acute carbon monoxide poisoning. METHOD: From 2012 to 2015 collected the MRI images of the 45 patients with acute carbon monoxide poisoning, observe their changes of middle ear and mastoid and sinus imaging. RESULT: The middle ear injury of mastoid 41 cases (91.1%), 22 cases (48.9%) of maxillary sinus injury, ethmoid sinus injury in 20 cases (44.4%), sphenoid sinus 9 cases (20.0%), 5 cases (11.1%) of frontal sinus injury. Carbon monoxide poisoning patients according to clinical symptoms can be divided into light, medium and heavy 3 groups, observing the ear sinus damage degree for comparison between groups, found to have significant differences (P < 0.05). CONCLUSION The patients with acute carbon monoxide poisoning ear and sinus injury should cause the attention of the medical staff, MRI can reflect people's ears from the details and the damage degree of the sinuses.

We present an analysis method of electrocardiogram (ECG) to determine patients' ventricular late potentials (VLPs) characteristics by means of wavelet packet transform and entropy (ApEn). The results indicate that the patients with VLPs tend to have higher ApEn values than do those without. So ApEn can be used as an indicator and a BP neural network for distinguishing between the two patient groups. The experiment result shows that this method has higher distinguishability.

OBJECTIVE: To analyze the principle mechanism of the arcus plantaris and its clinical application. METHODS: The states of forces sustained by the arcus plantaris were analyzed and calculated according to the mechanism of the quadratic parabolic arch. RESULTS: The aponeurosis plantaris corresponded to the pull rod of the arcus plantaris. The medial and lateral longitudinal arches formed by the pedal bones were stable with the rod, but unstable without the rod. In the latter condition, on loading, the force sustained by the parabolic arch became a force sustained by a simple beam, and the arcus plantaris tended to disappear and to be flattened. Clinically, 240 feet with talipes equinus were treated with triple arthrodesis. In 34 out of the reexamined 156 feet, the aponeurosis plantaris was cut in addition to the triple arthrodesis and was immobilized with cast for 3 months. One or two years later, their arcus plantaris disappeared, pain developed when walking, and some of them walked with the midtarsal joint against the ground. Then, the triple arthrodesis and shortening of the aponeurosis plantaris were applied on 18 cases, and osteotomy of the calcaneus and reconstruction of the aponeurosis plantaris were made on 10 cases and satisfactory effects were obtained. CONCLUSIONS: In order to achieve satisfactory therapeutic effects of the triple arthrodesis, we should reestablish the arcus plantaris and accurately treat the aponeurosis plantaris for the balance of the surrounding muscle force.

OBJECTIVE： To systematically evaluate the efficacy and safety of cyclosporin combined with glucocorticoid versus cyclophosphamide combined with glucocorticoid in the treatment of membranous nephropathy （MN）. METHODS： Retrieved from Embase， Medline， CNKI， VIP and Wanfang database， RCTs about cyclosporin combined with glucocorticoid （trial group） versus cyclophosphamide combined with glucocorticoid （control group） in the treatment of MN were collected. Meta-analysis was conducted by using Rev Man 5.3 statistical software after literature screening， data extraction and quality evaluation with Jadad scale. RESULTS： Totally 6 RCTs were included， involving 312 patients in total. Results of Meta-analysis showed that remission rate 3 months after treatment [OR＝3.42，95％CI（2.05，5.71），P＜0.000 01] and relapse rate [OR＝3.12，95％CI（1.45，6.70），P＝0.004]， leukocyte count 12 months after treatment [MD＝1.77，95％CI（0.96，2.58），P＜0.000 1] in trial group were significantly higher than control group. There was no statistical significance in remission rate 6 months after treatment [OR＝2.06，95％CI（0.80，5.30），P＝0.13] and remission rate 12 months after treatment [OR＝1.30，95％CI（0.68，2.48），P＝0.42]， blood creatinine level 3 months after treatment [MD＝－1.55，95％CI（－6.72，3.62），P＝0.56] and blood creatinine level 6 months after treatment [MD＝－1.21，95％CI（－5.96，3.54），P＝0.62]， cholesterol level 12 months after treatment [MD＝－0.77，   95％CI（－1.81，0.28），P＝0.15] or ALT level[MD＝－0.40，95％CI（－4.38，3.58），P＝0.98] between 2 groups. ADR were reported in 5 RCTs， but their results were different. CONCLUSIONS： Long-term efficacy of cyclosporine combined with corticosteroid is similar to that of cyclophosphamide combined with corticosteroid in the treatment of MN. Cyclosporin combined with glucocorticoid has a faster effect， but a higher relapse rate.
