Objective To determine the expression of serum proteins in pancreatic cancer patients based on mass spectrometry to screen differential proteins and to find potential molecular biomarkers to prediagnosis of pancreatic cancer. Methods The technique of isobaric tags for relative and absolute quantitation (iTRAQ) and two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS) were used to analyze the serum proteins in 15 pancreatic cancer patients and 10 healthy controls. Screening for serum differential proteins was performed via retrieving Panther, Mascot and Scaffold databases. Ingenuity Pathway Analysis was used to detect the correlation between proteins. Results The expression level of 442 proteins was quantified, and 76 proteins were found to be differentially expressed which changed corresponding biological process. The up-regulation of DNA repair protein 50 (RAD50) and down-regulation of transforming growth factor β1 (TGFβ1) and apoptosis protease-activating factor 1 (APAF1) which were correlated with cell growth and apoptosis were found in pancreatic cancer. A closely interacted network was formed between these three differential proteins and other molecules, which could effect metabolism in pancreatic cancer patients. Conclusion Differential expression of serum proteins screened by iTRAQ in pancreatic cancer patients may be the potential markers of pancreatic cancer, which can provide molecular basis for early diagnosis of pancreatic cancer.

Objective: To explore the effects of ulinastatin on the level of MIF in rats with acute necrotic pancreatitis. Method: 52 healthy Wister rats were randomly divided into three groups: normal control group(group C, 12), ANP group(group A, 20)and UTI group(group U, 20). Severe acute pancreatitis rat model in group A were induced by injection of 315 % sodium taurocholate through retrogradely common biliopancreatic ducts via papilla duodeni. After inducing the rat model of ANP through the way above, rats in group U were treated by ulinastatin through portal vein injection. Pancreas and duodenum were only flipped after opening abdominal cavity in group C. Then rats were killed at 3rd, 6th ,12th ,24th hour after operation respectively. Cut the belly open at once, and draw blood in postcava. The levels of serum MIF were determined with ELISA. Blood amylase was detected through biochemistry instrument. Resected pancreas tissues was scored according to the standard of Kusske. Result: Compared to the normal control group, the level of serum MIF , blood amylase and histopathological scores were significantly increased in ANP group, P

Objective To explore the impact of the ratio between pelvic tilt (PT) and sacral slope (SS) on the life quality of patients with ankylosing spndylitis (AS) after kyphosis correction. Methods From November 2008 to May 2011, 33 AS pa?tients were reviewed, including 31 males and 2 females, aged from 19 to 58 years old (average, 36 years old). The thoracolumbar kyphosis angle was 35.23° ± 13.98° (range, 15.12°-74.37° ) and the lumbar lordosis angle was 8.68° ± 18.27° (range,-23.70°-62.15°). The Scoliosis Research Society (SRS)?22 questionnaire was used to evaluate the quality of life and the Oswestry disability index (ODI) was used to evaluate the condition of pain. The pelvic incidence (PI), PT, SS, sagittal vertical axis (SVA) and osteoto?my angle were obtained from standing lateral full?spine radiographs. The correlations were analyzed from the subjective grading and the sagittal parameters in AS patients. Results The osteotomy site was in L1 (5 cases, 21.00°-54.59° , average 32.59° ± 13.44° ), L2 (19 cases, 28.63°-66.24° , average 37.89° ± 9.26° ), L3 (9 cases, 31.78°-60.90° , average 47.05° ± 9.20° ), respectively. The range of osteotomy angle was 39.59°±10.82° (range, 21.00°-66.24°). The subjective grading and spino?pelvic parameters were improved significantly after operation except PI, only postoperative PT/SS (0.93±0.65) and ODI standing (0.60±0.75)(r=0.681, P<0.05), osteotomy angle (39.59°±10.82°) and satisfaction of management (3.33±0.49)(r=0.478, P<0.05)had correlation with the subjective grading. Conclusion Compared with the change of PT, SS and SVA, the change of PT/SS is more closely related to the quality of life after operation in AS patients with kyphosis, which should be pay attention to by surgeon when designing operative schemes.

Objective To explore the relationship between HLA?B allele polymorphisms and nasopharyngeal carcinoma ( NPC) in Xinjiang, China and its clinical significance. Methods A total of 226 patients were assigned to NPC group, while 207 healthy volunteers were assigned to control group. PCR amplification with sequence?specific primers was used to determine HLA?B alleles. Comparison of HLA?B allele frequency between the above two groups, between Han and Uygur populations, and between patients with various clinical characteristics of NPC was made by chi?square test. The Kaplan?Meier method was used to calculate the survival rates and the log?rank univariate analysis was used to explore the relationship between survival rates and HLA?B allele frequency. Results In all the subjects or Han population alone, the allele frequency of HLA?B?46 in the NPC group was significantly higher than that in the control group ( P=0. 000;P=0. 000 ) . In Uygur population, however, there was no significant difference in the allele frequency of HLA?B?46 between the NPC group and the control group (P>0. 05). In the patients with NPC, those less than 30 years old had a significantly higher allele frequency of HLA?B?44 than those no less than 30 years old (P=0. 029);those with differentiated non?keratinizing carcinoma had a significantly higher allele frequency of HLA?B?48 than those with undifferentiated non?keratinizing carcinoma ( P=0. 029);those with stage T1+T2 disease had a significantly higher allele frequency of HLA?B?48 than those with stage T3+T4 disease ( P=0. 029) . The 5?year overall survival, disease?free survival, distant metastasis?free survival, and local relapse?free survival rates had no relationship with the expression of HLA?B?46, HLA?B?44, or HLA?B?48 in NPC patients ( all P>0. 05) . Conclusions HLA?B?46 allele is probably a NPC susceptibility gene in Han population in Xinjiang. HLA?B?44 is probably associated with early age of onset, while HLA?B?48 is probably associated with the pathological type and T stage of NPC. Therefore, HLA?B alleles are probably associated with the development and progression of NPC.

Objective To compare the safe zone and safe angles between males and females for screw placement on the medial iliosciatic plate for acetabular posterior column using 3D reconstruction technique.Methods Normal pelvic CT scans of 52 adults (27 males and 25 females;aged from 18 to 74 years,averaging 47.2 years) were obtained to create pelvic 3D models.After the acetabulum was thickened by 5 mm,the width (d) of the safe zone for placement of the medial iliosciatic plate was measured.After the vertical distance (w) between the vertex of the obturator canal and the greater sciatic notch was measured,the ratio (r) of d/w was calculated.The recombined innominatum model was cut through the center of the acetabulum with a plane perpendicular to the quadrilateral plate and the greater sciatic notch.The cross-section was marked as M.In males,4 points at distances of 1.0 cm,1.5 cm,2.0 cm and 2.5 cm anterior to the greater sciatic notch were marked.At the 4 points,the angulations (∠ a,∠b,∠ c and ∠ d) between the quadrilateral plate and the tangent line of the outer edge of the thickened acetabulum model were measured on the cross-section M.In females,3 points at distances of 1.0 cm,1.5 cm and 2.0 cm anterior to the greater sciatic notch were marked before ∠a,∠b,and ∠c were measured.The differences in the above parameters were compared between males and females.Results The width (d) of the safe zone for placement of the medial iliosciatic plate was 28.56 ±2.44 mm in males and 24.36 ±2.47 mm in females;the ratio (r) was 0.61 ± 0.07 in males and 0.54 ± 0.05 in females.The safe angulations for screw placement in males,∠ a,∠b,∠cand ∠d,were 88.04°±3.18°,77.81°±3.85°,68.01°±4.11°and56.81°±4.81° while those in females,∠a,∠b and ∠c,were 91.29°±4.52°,76.23°±3.82° and 62.79°±3.51°,respectively.There were statistically significant differences between males and females in values of d,r,∠ a and ∠ c (P ＜ 0.05).Conclusions In fixation of acetabular posterior column fractures using medial iliosciatic plate,the differences between males and females should be taken into account.Besides,specific safe angles should be chosen according to the position of the plate.

Objective To investigate the dynamic changes of blood-brain barrier(BBB) permeability after acute cerebral ischemia in rats with middle cerebral artery occlusion (MCAO) by dynamic contrast-enhanced(DCE)-MRI. Methods Sixty MCAO rat models were established by suture-occlusion method. All rats were divided randomly into twelve groups with different ischemia duration (3 hours, 6 hours, permanent) and reperfusion times (2, 6, 12 and 24 hours after reperfusion). Each group was examined by MRI at the time points. The BBB permeability parameters(Ktrans, Ve, Kep, rKtrans, rVe, rKep) were calculated by Siemens workstation and compared with Evans blue(EB) extravasation results. Multivariate analysis of variance (M-ANOVA), one-way analysis of variance (one-way ANOVA), Pearson analysis were respectively used to verify the influences of ischemia duration and reperfusion time on BBB permeability parameters, EB extravasation and relationships between parameters. Results In 3 hours and 6 hours ischemia duration groups, change of BBB permeability after reperfusion appeared biphasic. At 2 hours and 6 hours after reperfusion, BBB permeability increased, while rKtrans values and rVe values rose and rKep values dropped. BBB permeability decreased at 12 hours and increased again at 24 hours after reperfusion. The highest BBB permeability was observed at 6 hours after reperfusion. However, BBB permeability in permanent ischemia groups had uniphasic change, as its increase was rather mild as ischemia time went on. rKtrans values(1.99± 0.79)were positively correlated with rVe values(2.88 ± 1.78) (r=0.93, P<0.01) and negatively correlated with rKep values(0.66 ± 0.21) (r=-0.84, P<0.01). The negative correlation between rVe values and rKep valueswas also significant(r=- 0.80, P<0.01). EB extravasation results were consistent with MRI findings. Conclusions BBB permeability change was biphasic in reperfusion groups, while it was uniphasic in permanent ischemia groups. DCE-MRI may accurately reflect the changes of BBB permeability after acute cerebral ischemia. Both ischemic duration and reperfusion time had influences on BBB permeability. With prolongation of ischemic time, the duration of BBB permeability increase became shorter, BBB damage appeared earlier, with increased degree of ischemic damage.

Objective To investigate the expression of heparanase (Hpa) in serum and tissue of patients with papillary thyroid carcinoma (PTC) and its clinical significance.Methods Immunohistochemical method (SP) and enzyme linked immunosorbent assay (ELISA) were used to detect the expression of Hpa protein in serum and tissues of 38 cases of PTC,37 cases of patients with benign thyroid nodules,and 30 normal controls.Results Expression of Hpa in PTC was higher than that of benign thyroid nodules (P＜0.01).Expression of Hpa in lymph node metastasis group was higher than that in group without lymph node metastasis (P＜0.05).Compared with the normal control group,the content of serum Hpa in patients with benign thyroid nodules had no significant difference (P＞0.05).Hpa content in serum of patients with PTC was higher than that of benign thyroid nodules group and the normal control group (P＜0.01).There was no statistically significant difference of the level of serum Hpa between groups with and without lymph node metastasis.Conclusions Detecting tissue and preoperative serum Hpa concentration is valuable for diagnosis of PTC.Hpa detection in tissues can be used to determine whether there was lymph node metastasis in PTC patients,while Hpa detection in preoperative serum can not judge whether there is lymph node metastasis.

Objective To study the relationship between heparanase( Hpa) , urokinase type plasminogen activator( uPA) expression and lymph node metastasis in thyroid carcinoma.Methods Immunohistochemieal SP method was used to analyze the expression of Hpa and uPA in 113 cases of thyroid carcinoma and 134 cases of be-nign thyroid nodules.The expression of Hpa and uPA in thyroid carcinoma and its clinical significance were ana-lyzed.Results The positive expression rate of Hpa and uPA in thyroid carcinoma and benign nodular thyroid tis-sue were 82.30%,16.42%and 89.38%, 11.19%.The positive expression rate of Hpa and uPA in carcinoma tissues with lymph metastasis and without metastasis were 93.94%,100% and 65.96%,74.47%.Expression of Hpa and uPA in thyroid carcinoma group was significantly higher than that of benign thyroid nodules group( P<0.001) .The rate of positive expression in lymph metastatic tissues were significantly higher than those in tissue without metastasis( P<0.001) .Hpa and uPA expression in thyroid carcinoma tissues was positively correlated( r=0.437, P=0.021).Conclusion The expression of Hpa and uPA is closely related with the occurrence and metastasis of thyroid carcinoma.

Objective To explore the clinical efficacy of medial iliosciatic plating via the Stoppa approach for complex acetabular fractures involving the posterior column.Methods Between February 2015 and February 2016,a total of 16 complex acetabular facture cases treated by the medial iliosciatic plate via the Stoppa approach were retrospectively analyzed in this study.This approach provided good exposure to a large region of the pelvis and acetabulum including pubis symphysis,pubic ramus,anterior and inner wall of acetabulum,quadrilateral surface,inner surface of posterior column,true pelvic margin,greater sciatic notch and sacroiliac articulation.The anterior and column was reduced and fixed by the anterior column plate and the medial ilioseiatie plate.The screw direction and angle were adjusted according to the intraoperative X-ray.Surgical time,amount of bleeding,and relevant complications were recorded.The reduction of the posterior column fracture was evaluated by Matta scoring system on the plain X-ray of the pelvic post-surgery,and functional outcomes of the hip joint affected were evaluated one year post-surgery by the Merle d'Aubigne-Postel scoring system.All the cases were followed for at least 12 months.Results The reduction and fixation of the posterior column was accomplished in all the 1 6 patients.The average surgical time was 165.5 min (range,130-270 min).The average blood loss was 1 245.6 ml (range,600-5 600 ml).Thc intraoperative infusionof concentrated red blood cells averaged 6 units.According to the Matta scoring system,anatomical reduction was achieved in 12 cases,satisfactory reduction in 3,and poor reduction in one.The patients were followed from 12 to 22 months.According to the Merle d'Aubigne-Postel scoring system,there were 11 cases of excellent and 3 cases of good,yielding a good or excellent rate of 87.5％.The average Merle d'Aubigne-Postel score was 15.8 (range,8-18).There were 1 case of external iiiac vein rupture and 1 case of bladder rupture.Both were repaired during surgery.Superior gluteal artery rupture was found in 1 case and surgical ligation of the artery was performed during surgery.Conclusion In the treatment of complicated acetabular fractures involving the posterior column,the medial iliosciatic plating via the Stoppa approach is safe and effective,because it can provide a safe and sufficient operative field for surgeons to reduce and fix the posterior column fractures,and it leads to satisfactory recovery of the patients with limited complications.
