To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

Objective: To summarize the effect of modified David technique on acute type A aortic dissection sinus formation. Methods: From March 2018 to September 2018, modified David technique was applied to aortic sinus remodeling in acute A-type aortic dissection in 19 patients, 13 males and 6 females. The age was 45-67(50.42±15.37) years old and the weight was 45-112(60.32±25.18) kg. Single sinus(noncoronary sinus) was repaired in 15 cases, double sinus formation(noncoronary sinus+ right coronary sinus+ coronary artery transplantation) in 2 cases, left sinus Florid sleeve technical treatment plus double sinus formation(noncoronary sinus+ right coronary sinus+ coronary artery transplantation) in 1 case, Single sinus(noncoronary sinus) repaired and aortic vavle replacement in 1 case. Frozen elephant trunk and total arch replacement in 13 cases, hemiarch replacement in 3 cases. Results: There were no deaths in this group. The cardiopulmonary bypass time was 176-245(193.27±32.46) minutes, the aortic cross clamp time was 105-187(122.36±18.57)minutes, and the operation time was 6.5-11.0(7.63±1.31) hours. The mechanical ventilation time was 18-122(48.27±34.73)hours, the intensive care unit stay time was 2-10(5.35±2.62) days, and the postoperative hospital stay was 7-22(12.63±3.25)days. There was no delayed sternal closure during operation, and there was no secondary thoracotomy after operation. One patient developed a transient advanced atrioventricular block. Transient neurological dysfunction was observed in 5 patients. All patients were followed up for more than half a year. The color Doppler echocardiography and computed tomography angiograph(CTA)showed no aortic regurgitation or residual dissection. Conclusion The application of modified David technique in the remodeling of aortic root sinus in acute type A aortic dissection is an effective technique with relatively simple process, which is worth promoting.

Objective To evaluate the clinical application of early total care (ETC) for polytrauma patients combined with thoracolumbar fractures.Methods A retrospective case control study was conducted to analyze the clinical data of 137 polytrauma patients combined with thoracolumbar fractures admitted to the First Affiliated Hospital of Soochow University and the Third People's Hospital of Zhang,jiagang from January 2012 to October 2015.There were 90 males and 47 females,aged 26-69 years,with an average age of 48.2 years.The patients were divided into ETC group (n =59) and TMC group (n =78).In the ETC group,physicians from different departments evaluated the patients and developed individualized therapeutic regimens to allow the patients to undergo surgery at early stage after injury.The TMC group preferentially stabilized the patient's condition or transferred the patients to specialist treatment,and then the surgery was performed electively after the condition of the patient was stable.The ISS of the ETC group was (22.15 ± 9.28)points,and that of the TMC group was (23.37 ± 10.74) points.All patients underwent conventional posterior pedicle screw internal fixation.For patients with burst fracture and nerve injury,posterior spinal canal decompression was performed.The thoracolumbar injury classification and severity score (TLICS),spinal load sharing classification (LSC),preoperative and postoperative Glasgow coma score (GCS),Frankel classification,hospitalization time and postoperative complications were compared between the two groups.Results The TLICS scores of ETC group were significantly lower than those of TMC group (P ＜ 0.05) while the LSC scores showed no significant differences between the two groups (P ＞ 0.05).ETC group had shorter hospitalization time [(11.8 ± 3.7)days ∶ (17.5 ±4.5)days] and lower pressure ulcer incidence [(5％ ∶ 21％)] than the TMC group (P ＜ 0.05 or 0.01),but the former had significantly higher wound infection rate [(17％ ∶ 15％)] (P ＜ 0.05).There was no significant difference in pulmonary infection and deep venous thrombosis incidence between the two groups (P ＞ 0.05).No significant differences were found in the preoperative GCS scores between the two group (P ＞ 0.05) while the postoperative GCS scores of TMC group were higher than those of ETC group (P ＜ 0.01).Postoperative GCS scores in both groups were significantly higher than their preoperative GCS (P ＜ 0.05).The results of postoperative Frankel classification in the ETC group were as follows:Grade A in one patient,Grade B in one,Grade C in three,Grade D in four and Grade E in two patients,with an improvement rate of 82％.The results of postoperative Frankel classification in the TMC group were as follows:Grade A in three patients,Grade B in three,Grade C in three,Grade D in four and Grade E in four,with an improvement rate of 65％.Conclusions For polytrauma patients combined with thoracolumbar fractures,ETC can shorten hospitalization time,reduce the pressure ulcer incidence,and better facilitate the recovery of nerve function,yet with higher wound infection risk compared with TMC.TMC was preferred subjectively for patients with unstable thoracolumbar fractures and high TLICS.

Objective: To investigate the characteristics of acute myocardial infarction caused by spontaneous coronary artery dissection(SCAD) in young female patients. Methods: In this casecontrolstudy,127 young(≤55 years) female patients with acute myocardial infarction onset within 1 week in Nanjing first hospital, Xuzhou central hospital, affiliated hospital of Xuzhou medical university, and Lianyungang first people's hospital were enrolled between January 2013 and February 2017,and the clinical data were retrospectively analyzed. According to their clinical manifestations and coronary angiography(CAG) results,the patients were divided into coronary atherosclerosis disease(CAD) group(CAG evidenced atherosclerosis, n=83) and SCAD group(CAG detected coronary artery dissection,n=44).The SCAD patients were subdivided into definite group (the results affirmed from intravenous ultrasound or optical coherence tomography, n=21) and probable group (the CAG results highly confirmed to characteristics of SCAD,but no intravenous ultrasound or optical coherence tomography image affirmation,n=23). Then, according to the different treatment strategies, the SCAD patients were subdivided into conservative treatment group(treated with drugs,n=19) and interventional therapy group(treated with percutaneous coronary intervention,n=25). Results: (1)Compared to CAD group, patients in the SCAD group had less risk factors, such as hypertension history (25.0% (11/44) vs. 45.8% (38/83) , P=0.022) and diabetes history (6.8% (3/44) vs. 21.7% (18/83) , P=0.043),and had lower levels of fasting blood glucose (5.34(4.59,5.87) mmol/L vs. 7.12(5.18,8.60)mmol/L, P=0.001),total cholesterol((3.94±1.14) mmol/L vs. (4.91±1.50) mmol/L, P=0.001),triglyceride(1.42 (0.91,1.64) mmol/L vs. 1.89 (1.23,2.45) mmol/L, P=0.005),and low density lipoprotein cholesterol ((2.24±0.91) mmol/L vs. (2.94±1.16) mmol/L, P=0.001),CAG results showed that patients in the SCAD group had more single vessel lesion (88.6% (39/44) vs. 39.8% (33/83) , P=0.001), and their target lesion stenosis was less severe ( (79.2±22.4) % vs. (91.5±12.1) %, P=0.001). (2) The clinical risk factors such as hypertension history, diabetes history, smoking history, family history of cardiology disease, fasting blood glucose,total cholesterol,triglyceride and low density lipoprotein cholesterol were similar between definite group and probable group (all P>0.05). CAG results showed that prevalence of single vessel lesion (100% (21/21) vs. 78.3% (18/23) , P=0.050) and percent of target lesion stenosis ( (76.9±20.6) % vs. (81.2±24.1) %, P=0.529) were similar between definite group and probable group.(3)There were no significant difference in single vessel(84.0% (21/25) vs. 94.7% (18/19) , P=0.370), target lesion stenosis(85.0(70.0,100.0)% vs. 75.0(50.0,90.0)%, P=0.186),and survival rates in hospital(96.0% (24/25) vs. 100% (19/19) , P=1.000) between interventional therapy group and conservative treatment group. Conclusions Prevalence of SCAD is highin young female patients with acute myocardial infarction. Acute myocardial infarction patients with less risk factors of CAD and with CAG showing smooth lesion of narrowing segment and normal finding in the other vessels, are more likely to be diagnosed with SCAD.Acute myocardial infarction patients caused by SCAD have high survival rate either receiving percutaneous coronary intervention or drug treatment.

Objective Total aortic arch replacement and stented elephant trunk surgery is an important surgical method for acute type A aortic dissection, and the short, middle, long term curative effect has been recognized by more and more experts at home and abroad.Circulatory arrest was an independent risk factor for postoperative complications and mortality in patients with type A aortic dissection.The aim of this article is to observed the effection of a new technology to block aortic arch, whicn can shorten the circulatory arrest time to 2 minutes and avoid harm of circulatory arrest on patients.Methods From May 2016 to February 2017, 68 patients with acute type A aortic dissection were divided into the conventional group and the modified group.All the patients underwent total arch replacement and stented elephant trunk surgery.The rectal temperature of the conventional group was 25℃ and circulatory arrest time was 20 min.While the rectal temperature of the modified group was 28℃ and and circulatory arrest time was 2 min.Results In the conventional operation group, 3 patients died after operation while all the patients in the modified group were cured and discharged.There are no differences between the two groups in the time of cardiopulmonary bypass(CPB) and heart arrest time(P>0.05).There are Significant differences in CPB time, circulatory arrest time, postoperative awake time, intubation time, amount of blood used, the amount of drainage during the first two days after operation, the time staying in ICU and the postoperative time in hospital.And the modified group was much better.(P<0.05)Conclusion The results of new technology blocking aortic arch in the patients with acute type A aortic dissection are better than the conventional surgical approach during the perioperative period.This technology is simple and effective.It is worth promoting.

Objective To investigate the effect of occult HBV infection (OBI) on carcinogenesis of cryptogenic hepatocellular carcinoma.Methods Samples of hepatocellular carcinoma (HCC) and pericarcinomatous tissues obtained after hepatectomy from January 2011 to November 2013 at the Third Affiliated Hospital of Sun Yat-Sen University were collected.They were divided into two groups:the cryptogenic HCC group (the CH group,n =26) and the HBV related HCC group (the HH group,n =40).These samples were compared with the normal liver tissues obtained in 30 patients.HBV DNA was identified by the nested polymerase chain reaction and the immunohistochemical method was taken to examine the hepatitis B virus X protein (HBx) and Yes-associated protein (YAP) expressions.Results OBI was identified in 20 (77.8％) cryptogenic HCC patients and 8 (26.7％) in the control group.There was a significant difference between the two groups (x2 =14.072,P ＜ 0.05).HBV DNA was detected in all the HBV-related HCC patients.The HBx protein expression was mainly located in the cytoplasm of liver cells and liver cancer cells,but YAP was expressed in the nucleus.Both of them showed diffuse brown or tan particles.In the HH group and the CH group,the positive expression rates of HBx protein in the tumorous tissues were 80.0％ and 90.0％,respectively,and 85.0％ and 82.5％ in the nontumorous tissues,but only in 40.0％ in the control group.The positive expression rates of YAP in the tumorous tissues were 65.0％ and 67.5％,respectively,15.0％ and 20.0％ in the nontumorous tissues,respectively,but only in 12.5％ in the control group.The HBx expression in the cancerous tissues and para-cancerous tissues of the HH group and the CH group showed no significant difference (P ＞ 0.05),but the YAP expression in the tumor tissues was significantly higher than that in the nontumorous tissues (P ＜ 0.05).The HBx and YAP expressions in the HH group were comparable to the CH group (P ＞ 0.05).However,their expressions in the cancerous tissue of the HH group and the CH group were significantly higher than in the normal liver tissues (P ＜ 0.05).Conclusion A high prevalence of HBV infection was observed in HBsAg-negative HCC and the high expressions of HBx and YAP might be involved in the process of cryptogenic hepatocellular carcinoma.

Objective To investigate the role of transmembrane protein C0-029 in epithelial mesenchymal transition (EMT) induced by tumor necrosis factor alpha (TNFα) of intrahepatic cholangiocarcinoma (ICC) cells.Methods RT-PCR and Western blot were conducted to detect the CO-029 expression in ICC cells and tissues.The effect of CO-029 silencing by lenti-virus on EMT induced by TNFα was investigated.Western blot and mass spectrometry after immunoprecipitation were used to confirm whether TNFαR1 can directly or indirectly bind with CO-029 to form complexes in ICC.Results Differential expression of CO-029 was observed in ICC cells and tissues.The expression of CO-029 was significantly reduced by lenti-viral interference in ICC cells,resulting in the failure of TNFα to induce EMT.TNFαR1 in ICC could directly or indirectly form complexes with CO-029.Conclusion CO-029 mediates TNFα/TNFαR1 induced EMT in ICC,which might play an important role in the invasion and metastasis.

Objective To investigate the expressions of tetraspanin CO-029 in intrahepatic cholangiocarcinoma (ICC) and to find out their clinical significance.Methods RT-PCR and western blot were used to detect the expressions of CO-029 in ICC and their matched para-tumorous tissues from 20 patients with ICC,as well as in the HCCC-9810 cell lines.The expressions of CO-029 were further detected via tissue microarray (TMA) in the pathological specimens of 40 patients with ICC.Correlations between the expressions of CO-029 and the clinicopathologic features and prognosis were analyzed.Results A high level of CO-029 was detected in the 20 patients with ICC and the HCCC-9810 cell lines via western blot and RTPCR.Moreover,the expression levels of CO-029 in the ICC tissues were higher than the matched para-tumorous tissues (P ＜ 0.05).TMA detection revealed the positive expression rate of CO-029 to be 65％ (26/40).The expression level of CO-029 was much higher in the early recurrence group (Time to recurrence,TTR ＜ 1 year) than the non-recurrence group (TTR≥ 1 year).On analysis,the correlations were significant between the expressions of CO-029 and tumor encapsulation,hilar lymph node metastasis,TNM stage and prognosis (P ＜0.05).Conclusions CO-029 was highly expressed in ICC.It had close correlations with recurrence,metastasis and prognosis of patients with ICC.
