Objective To evaluate the safety and diagnostic accuracy of preoperative endoscopic ultrasound-guid﹣ed fine-needle aspiration in patients with pancreatic cancer. Methods 256 patients with pancreatic cancer from Jan﹣uary 2010 to December 2014, 82 were considered resectable on the basis of cross-sectional imaging findings. Of these patients, 54 underwent EUS-FNA before surgery (FNA+group) and 28 underwent surgery without preoperative EUS-FNA (FNA- group), the diagnosis result of EUS-FNA and the survival time of the two groups were observed. Results All 54 lesions were visible on EUS, and all 54 attempts at FNA were technically successful. The diagnostic accuracy according to cytology and histology findings was 94.44 % (51/54) and 88.89% (48/54), respectively, and the total accuracy was 94.44 % (51/54). Two patients developed mild pancreatitis and two hemorrhage after EUS-FNA but were successfully treated by conservative therapy. No severe complications occurred after EUS-FNA. In the FNA+and FNA- groups, the median relapse-free survival (RFS) was 282 and 265 d, respectively (P>0.05), and the median overall survival (OS) was 568 and 557 d, respectively (P>0.05). RFS and OS were therefore not inferior in the FNA+group. These data indicate that the usage of EUS-FNA did not influence RFS or OS, nor did it increase the risk of other complications. Conclusions Preoperative EUS-FNA is a safe and accurate diagnostic method.

OBJECTIVETo summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.
METHODSThe clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.
RESULTSSix operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.
CONCLUSIONGanglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.

BACKGROUNDIn qualitative diagnosis of bile duct stenosis, single diagnostic measure is difficult to make a correct diagnosis, to combine several diagnostic techniques may be helpful to make an accurate diagnosis. The aim of this study was to evaluate the value of intraductal ultrasonography (IDUS), endoscopic brush cytology and K-ras, P53 gene mutation in the early diagnosis of malignant biliary stricture.
METHODSFrom February 2012 to February 2013, 84 patients with suspected malignant biliary stricture were performed IDUS firstly, then endoscopic brush cytology and finally K-ras, P53 gene mutation detection, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of all above ways were evaluated and compared.
RESULTSOf 84 patients, 52 cases were ultimately diagnosed malignant biliary stenosis; of which, 9 cases had no recurrence or metastasis to other organs after radical operation during the follow-up period. IDUS combined with brush cytology and K-ras + P53 gene mutation detection had obvious advantage in the sensitivity, accuracy and negative predictive value than any other joint detection and single detection (the advantage was more significant compared with IDUS + brush cytology or any single detection P < 0.01). There were obvious statistical significance in the sensitivity and accuracy between IDUS + brush cytology + P53 or IDUS + brush cytology + K-ras and IDUS + brush cytology or IDUS (P < 0.05). There was no statistical significance in the sensitivity, specificity, positive predictive value, negative predictive value and accuracy between IDUS + brush cytology + P53 and IDUS + brush cytology + K-ras (P > 0.05).
CONCLUSIONSIDUS combined with brush cytology and K-ras, P53 gene mutation detection is better than the separate detection and contribute to the early diagnosis of malignant biliary stricture. Its more widespread use is recommended.

BACKGROUNDThis study was to examine the expression of total vascular endothelial growth factor (VEGF) and the anti-angiogenic VEGF 165 b isoform in the vitreous body of retinopathy of prematurity (ROP) patients, and to further study the role of the VEGF splicing in the development of ROP.
METHODSThis was a prospective clinical laboratory investigation study. All patients enrolled received standard ophthalmic examination with stage 4 ROP that required vitrectomy to collect the vitreous samples. The control samples were from congenital cataract patients. The expression of total VEGF and the anti-angiogenic VEGF 165 b were measured by enzyme-linked immunosorbent assay. Results were analyzed statistically using nonparametric tests.
RESULTSThe total VEGF level was markedly elevated in ROP samples while VEGF 165 b was markedly decreased compared to control group. The relative protein expression level of VEGF 165 b isoform was significantly decreased in ROP patients which were correlated with the ischemia-induced neovascularization.
CONCLUSIONSThere was a switch of VEGF splicing from anti-angiogenic to pro-angiogenic family in ROP patients. A specific inhibitor that more selectively targets VEGF 165 and controls the VEGF splicing between pro- and anti-angiogenic families might be a more effective therapy for ROP.

OBJECTIVE To examine the synergistic inhibiory effect of combination of mammalian target of sirolimus (Rapamycin) (mTOR) inhibitor everolimus and AKT inhibitor MK-2206 on hepatocar-cinoma cell proliferation. METHODS HepG2 and BEL-7402 cells were treated with sirolimus and evero-limus alone for 0, 1, 3, 6, 12 and 24 h or in combination with insulin-like growth factor 1 receptor (IGF-1R) inhibitor NVP-AEW541 or AKT inhibitor MK2206 for 24 h. p70S6K and AKT kinase activityies were detected by Western blotting. Plate clone formation assay and CCK8 assay were used to detect the growth and proliferation of hepatocarcinoma cells treated with everolimus and MK2206 alone or in combi-nation. RESULTS Sirolimus and everolimus inhibited p70S6K activity while causing feedback activa-tion of AKT kinase activity at different time points (P<0.01). NVP-AEW541 and MK-2206 could inhibit AKT kinase feedback activation by everolimus (P<0.05). Colony formation of hepatocarcinoma cells treated with everolimus and MK-2206 in combination was significantly inhibited compared with everolimus or MK-2206 alone (P<0.01). Everolimus and MK-2206 in combination inhibited the proliferation rate of two types of hepatocarcinoma cancer cells by more than 45% compared with everolimus used alone (P<0.01). CONCLUSION The resistance of sirolimus and its derivatives in hepatocellular carcinoma cells may be achieved throngh the feedback-activated PI3K/AKT pathway, and the combination therapy can synergistically inhibit the growth and proliferation of hepatocarcinoma cells.
