BACKGROUND:In recent years, a single-door laminoplasty for cervical spondylotic myelopathy was performed in the Department of Orthopedics, the First Affiliated Hospital of Zhengzhou University. This surgery achieved spinal decompression while remaining the important structure of cervical vertebra.
OBJECTIVE:To comparatively analyze the therapeutic effects of minimal y invasive cervical laminoplasty and single-door laminoplasty on cervical spondylotic myelopathy.
METHODS:A total of 78 cases of cervical spondylotic myelopathy were randomly divided into two groups, which respectively received minimal y invasive cervical laminoplasty and single-door laminoplasty.
RESULTS AND CONCLUSION:Al cases were fol owed-up for 3-36 months. No significant difference in excellent and good rate of Japanese Orthopaedic Association score was detected between the two groups in final fol ow-up (P>0.05). The apparent rate of axial symptoms was significantly lower in the minimal y invasive cervical laminoplasty group than that in the single-door laminoplasty group after treatment (P<0.05). Cervical curvature loss was significantly lower in the minimal y invasive cervical laminoplasty group than that in the single-door laminoplasty group (P<0.05). In final fol ow-up, in the minimal y invasive cervical laminoplasty group, two titanium screws of one patient were slightly loose, and no abnormal symptom was observed. In the single-door laminoplasty group, hinge breakage was visible in six patients. The broken vertebral plate was excised. Artificial spinal dura mater was coated on the surface of spinal cord for protection. Results suggested that the effect of two surgical methods in promoting functional recovery of spinal cord is identical. However, complications in the minimal y invasive cervical laminoplasty group are further fewer than those in the single-door laminoplasty group.

OBJECTIVETo study the significance of P504s in differential diagnosis between solid pseudopapillary tumor of the pancreas (SPTP) and pancreatic neuroendocrine tumors (PanNET).

METHODSForty-three patients with SPTP and 41 patients with PanNET encountered during the period from 2007 to 2014 were recruited. Immunohistochemical study for vimentin, CD10, chromogranin A, synaptophysin, beta-catenin, CD99 and P504s in SPTP and PanNET was performed. The diagnostic value of P504s in differentiating SPTP from PanNET was analyzed.

RESULTSImmunohistochemical study showed that vimentin, CD10, chromogranin A, synaptophysin and CD99 were expressed both in SPTP and PanNET. All cases of SPTP showed granular cytoplasmic expression of P504s, whereas those of PanNET were negative.

CONCLUSIONP504s is a sensitive and useful marker for SPTP and can be used in the distinction between SPTP and PanNET.

Bedridden patients mostly use the back cushion object,raise the bedside position,and other methods to obtain the semi-decumbent position.However,the existing methods have shortcomings such as insufficient execution,wrong angle estimation,weak consciousness,forgetting,decreased comfort,easy to cause pressure sore and aspiration pneumonia.To solve the shortcomings of the existing eating position placement method,the department of geriatric medicine team of Tongxiang City Hospital of Traditional Chinese Medicine designed a bed-rest pillow for bed patients to eat or other requirements of semi-lying position,and obtained the National Utility Model Patent of China(patent number:ZL 202122859891.4).This device places the pillow on a flat bed,with the back of the pillow next to the head of the bed for support and to prevent sliding.The patient was placed in a retainer slot,head in the first retainer slot,shoulder and back in the second retainer slot,waist and abdomen in the third retainer slot,and hands on the armrests on both sides of the pillow.The use of pillows for bedridden patients is simple and easy to learn,convenient,economical and practical,time-saving and labor-saving,and convenient supervision and inspection,which can reduce complications such as aspiration and pressure ulcers,thereby reducing the economic burden of the patient,improving the quality of life,and improving the satisfaction of patients and their families,and is worthy of clinical promotion and use.
