Objective To investigate the expression of LRP16 gene in lung cancer, and explore its clinicopathological significance. Methods Fresh resected tissues from 54 patients with primary lung cancer were collected and the clinicopathological data were gathered. The expression of LRP16 protein in cancer tissues and the matched normal tissues were determined by Western blotting, and the relationship between LRP16 expression and clinicopathological data was analyzed. It was defined as overexpression when the LRP16 expression of cancer tissues was twice or more higher than that of matched normal tissues. Results The LRP16 was overexpressed in 15 out of 54 patients with lung cancer (27.8%). Among the 23 patients with adencarcinoma, the overexpression of LRP16 was found in 11 cases (47.8%), while in the patients with squamous carcinoma, the overexpression of LRP16 was only found in 4 out of 27 cases (14.8%), and there was a significant difference between the two groups (Pearson test, P=0.0258). Besides, very low expression or non-expression of LRP16 was found in 2 large cell lung cancer and 2 small cell lung cancer. The overexpression rate of LRP16 was 20.0% (2/10) in tumor with diameter less than 3cm and 29.5% (13/44) in tumor with diameter ≥3cm, and there was no significant difference between the two groups (Pearson test, P=0.7224). Conclusions There were significant differences of LRP16 overexpression in cases of adencarcinoma or squamous carcinoma with or without lymphatic metastasis. It is suggested that LRP16 is a tumor-related gene of lung cancer, and may play an important role in molecular staging of lung cancer.

Objective To summarize the characteristics on diagnosis and therapy of adult diaphragmatic eventration. Method The clinical data of 26 patients with adult diaphragmatic eventration, hospitalized in General Hospital of PLA from 1988 to 2009, were retrospectively analyzed. The 26 patients, 14 males and 12 females, were aged from 26 to 66 (mean 44.0?5.7), with disease course of 8 months to 17 years. Among them 25 suffered from left and 1 from right diaphragmatic eventration; 24 with total and 2 with localized diaphragmatic eventration; of them 2 without symptoms were detected in physical examination, and among the 24 remainders 18 were with the symptoms of thoracic discomfort after eating, 8 with dyspnea after activities, 14 with hiccup, vomiting and abdominal discomfort. Most of the patients had more than one symptom. All patients received operations via the chest cavity under general anesthesia, 24 cases were performed by double mattress suture with diaphragm discission, while 2 cases by fold suture without diaphragm discission. Results Symptoms relief was reported in 24 patients at the early stage after operation. Eighteen patients were followed up for one year, and 15 of them received chest radiograph, among whom the normal diaphragm localization were in 13 cases and relatively higher diaphragm localization in 2 cases, while the other 3 patients received no re-examination of chest radiograph. Among the 18 cases receiving one year of follow-up, 10 cases got complete disappearance of symptoms, 6 cases got symptoms relieved or partially disappeared, and 2 patients got symptom relapsed. Conclusion Surgical outcome, especially the double mattress suture is satisfactory for adult diaphragmatic eventration.

BACKGROUND:Under physiological conditions, nerve roots can move along with the movement of limbs and spine. However, the mechanisms of nerve root stretch injury under physiological conditions and the neurological dysfunction after injury are unclear.
OBJECTIVE:To review the reason of nerve root stretch injury, and to analyze the mechanism of nerve function from biomechanics, pathology and neurophysiology.
METHODS:A computer-based online search of PubMed database was undertaken by the first author to identify the articles related to the research of nerve root injury and nerve stretch injury between 1990 and 2012, with the key words of“nerve root, nerve, stretch injury”. A total of 391 articles were screened out. The articles on the anatomy and biomechanics research of nerve root were included, as wel as the pathology and neurophysiology research after nerve root stretch injury. Final y, 44 articles were included for review.
RESULTS AND CONCLUSION:Nerve root can be stretched along with limbs and spine movement. However, diseases or trauma may cause pathological nerve root stretch, and thus leading neurological dysfunction. The nerve root is often influenced stretch because of its anatomical and tissue structure. Mechanical injury mechanism of stretch composes of peripheral (peripheral nerve conduction stress) and central mechanism (displacement of spinal cord content). Pathological studies found that the local fibrosis is caused by the extracted serum protein that difficult to remove after injury, and this is because of the shortage of lymphatic system in nerve roots. Fibrosis can cause nerve root ischemia, affect the nerve function, and change the biomechanical properties of nerve root. Nerve root injury can cause primary and secondary injury of internal axons, and this is the main reason for neurological dysfunction after injury.
