Objective To study the feasibility and the efficacy of total extraperitoneal repair (TEP) under two laparoscopes.Methods Clinical data of 51 patients with inguinal hernia who underwent TEP under two laparoscopes from July 2015 to March 2016 in our hospital were analyzed retrospectively.During TEP,we added a 5-mm laparoscope for monitoring and exploration in the abdominal cavity.Results All the operations of TEP under two laparoscopes were successful.The operation time lasted 42-176 min with a mean of (74 ±27) min.The intraoperative blood loss was 5-30 ml with a mean of (12.8 ±5.9) ml.The length of postoperative hospital stay was 2-7 days with a mean of (4.0 ± 1.1) days.The percentage of postoperative complications was 11.8％ (6/51),including inguinal area seroma which accounted for 2.0％ (1/51),inguinal region pain accounting for 3.9％ (2/51),and postoperative urinary retention for 5.9％ (3/51).No infection was found.The follow-up period ranged from 3 to 11 months (mean,7 months),no recurrence was observed during this period.Conclusions TEP under two laparoscopes can treat inguinal hernia precisely.It is also helpful to find compound inguinal hernia and occult inguinal hernia.

PBL ( Problem-based learning) is a problem-based and student-centered learning pattern.PBL teaching method has been applied to evidence-based medicine ( EBM ) courses for international students.By this method,the students' learning enthusiasm was stimulated,the ability of ananlyzing and resolving problem was improved,and good teaching effect was achieved,which provided knowledge to improve further EBM teaching and evidence-based clinical practice.

Purpose:To study clinical and pathological features of solid-pseudopapillary tumor(SPT) of the pancreas. Methods:The clinical data were reviewed in four patients with SPT. Immunohistochemistry for Vim, CK8, CK18, Chromogranin, Sy, AAT, NSE, S-100 was performed in all four cases using EnVision. Results:All four patients were female. The mean age was 30 years. The tumors were composed of papillary and solid structures. The uniform cells were strongly diffuse positive for Vim, and strongly positive for focal AAT in four cases. Three cases were positive for NSE. All four cases were negative for Sy , Chromogranin and S-100. One case was poorly positive for CK8 and CK18. Conclusions:SPT of the pancreas, preferentially in young women, is a tumor with low malignant potential. Immunohistochemistry is very important in the diagnosis and differential diagnosis of SPT of the pancreas..

Schwann cells (SCs) have potently neuroprotective and myelinization abilities. They are one of the earliest and the most frequently used cells that are applied to therapeutic studies in spinal cord injury. At present, SCs are usually used as a platform for therapeutic alliance to integrate various interventions. This review will mainly discuss the issues met in therapeutic alliances with SCs for spinal cord injuries, results of various therapeutic alliances with SCs, positive effects of co-transplantation with SCs on neural stem cells, survival, migration of SCs after transplantation and roles of endogenetic SCs in repairing spinal cord injury.

Against the deficiencies of the current preventive medicine education curriculum,training programs and curriculum were reformed according to the training objectives of the modem preventive medicine, while new ideas of preventive medical personnel training were explored in order to cultivate practical professionals with a certain ability to innovate and to adapt the development of modern public health and preventive medicine preferably.

Objective To explore the metabolic characteristic of prostate cancer (PCa) in central gland with magnetic resonance (MR) spectroscopic, and evaluate the value of MRS in the differential diagnosis of benign prostatic hyperplasia nodus. Methods MR images were performed in 38 cases with prostate disease by 3.0T MR, 11 cases with PCa in central gland and 27 cases with benign prostatic hyperplasia nodus. All the cases were scanned by routine, then by the combined MRS. MRS findings were reviewed in 27 cases with benign prostatic hyperplasia (BPH) and 11 cases with PCa (3 in central gland origin, 8 with large tumor invading both peripheral zone and central gland). (Cho+Cr)/Cit ratios of PCa and BPH were retrospectively measured, (Cho+Cr)/Cit of PCa voxels were compared with that of BPH voxels. Results Significantly higher choline levels and lower citrate levels were observed in central gland of PCa compared with BPH. In the glandular BPH region, the amount of Cit was high; while in the stromal region, the Cit and Cho level was much lower. The average (Cho+Cre)/Cit values of PCa and BHP were 1.94±1.43 and 0. 83±0. 28 respectively, the difference in ratio between both was statistically significant (P＜0. 01). Conclusions The combined use of MRI and MR spectroscopy is propitious for differentiating prostate cancer in central gland and benign prostatic hyperplasia nodus and for increasing the diagnostic accuracy of prostate cancer.

There is no a systemic performance metrics for clinical data management. While the CDMC in China starts to develop the quality metrics for clinical data management, it is essential to think over the performance and pursue metrics implementation of clinical data management in China. This article provides the basic concept, development and implementation of the performance metric in clinical data management.
