BACKGROUND: The formation mechanism of biliary cast syndrome following liver transplantation has not been thoroughly illuminated, and it is unclear that whether some proteins correlated to the formation mechanism of biliary cast or prewarning to the formation of biliary cast.OBJECTIVE: To investigate the holoprotein expression in biliary cast syndrome patients following liver transplantation. METHODS: Four patients underwent liver transplantation at Liver Transplantation Institute, General Hospital of Chinese People's Armed Police Force. Three months later, 10 g biliary cast was harvested. Four kinds of biliary cast specimens at different colors and textures were preserved at deep hypothermia, followed by protein abstraction and restriction enzyme digestion, the total protein abstraction solution of biliary cast were analyzed by high definition mass spectrometry and query on MASCOT database. All protein name of biliary cast were list, the conjunct protein was found by comparing 4 specimens. RESULTS AND CONCLUSION: There were totally 208 proteins in 4 biliary cast specimens, 82, 44, 56 and 65, respectively. By comparison, 5 proteins were found to overlay in 2 biliary cast specimens, 7 proteins in 3 specimens and 13 proteins in 4 specimens. Among the latter 13 proteins, 5 unnamed-proteins, as well as 8 named-proteins (termed alpha-fibrinogen precursor, beta-fibrinogen precursor, fibrinogen gamma chain, proapolipoprotein, Chain A of Human Cathepsin G, S100 calcium-binding protein A9, lactoferrin) were included. The proteins exists in biliary cast, the common proteins of 4 biliary cast specimens imply a correlation between the formation of biliary cast and the exudative inflammation following the damage of biliary tract epithelium; Some proteins might be considered as a marker of prewarning the presence of biliary cast syndrome, judging the inflammation severity following the damage of biliary tract epithelium and the prognosis of biliary cast syndrome.

Objective: To explore the effect of endostatin on the growth of human liver carcinoma in vivo. Methods: Mice endostatin gene was transferred into SMMC 7721 cancer established in nude mice. Immunohistochemistry and Western blot analysis were applied to examine the transfection and expression. The microvessel desity (MVD), the positive rate of vascular endothelial growth factor (VEGF) were studied using immunohistochemical methods. The growth of the cancer of the endostatin-transfected were observed. Results: Immunohistochemistry and Western blot proved endostatin expression and secretion from endostatin-transfected SMMC7721 cells, compared with negative control group, MVD and VEGF were lower (P

Objective To compare conventional T2-weighted MR cholangiography (T2WI-MRC) with gadobenate dimeglumine enhanced T1-weighted MR cholangiography(CE-MRC) for evalution of biliary anatomy in liver transplant donor candidates. Methods Thirty-two healthy liver transplant donor candidates were examined with two MR cholangiogaphic methods. For T2WI-MRC, a three-dimensional turbo spin-echo sequence and oblique coronal heavily T2-weighted thick-slab turbo spin-echo imaging sequence were performed. For CE-MRC, three-dimensional fat-suppressed spoiled gradient-echo sequences were performed, with a time delay of 60 minutes following the administration of gadobenate dimeglumine. To compare the depiction of biliary duct anatomy and the artifact caused by intestinal liquid and breathing between the two methods. Intraoperative cholangiography was the reference-standard examination. Results The both methods depicted the biliary anatomy correctly in all 9 cases. The both methods showed the third branches of intrahepatic biliary duct clearly. T2WI-MRC showed interhepatic bihary duct before the third branches in 28 cases (87.5%), CE-MRC showed the same finding in 14 cases (43.8% ). T2WI-MRC showed common bile ducts intermitantly in 2 cases, which were normal in CE-MRC and intraoperative cholangiography. Intestinal liquid affected the image quality of biliary duct in 6 cases (18.8%) performed with T2WI-MRC, but none with CE-MRC. The artifacts caused by breathing were not obvious in the either method. Conclusion T2WI-MRC and CE-MRC both can be used to evaluate bihary anatomy of liver transplant donor candidates, but CE-MRC appears to be more accurate than T2WI-MRC.

Objective To investigate the feasibility of measuring liver volume with Argus methoct Methods Thirty-two healthy liver transplant donor candidates underwent liver MRI on a 3.0 T MR unit.Volume interpolated body examination(VIBE)was performed after the administration of gadobenate dimeglumine.The VIBE data was transferred to the diagnostic workstation,and then multiple planar reconstruction(MPR)images were acquired.Firstly.two observers manually drawn the liver shape and calculated three volumes:the whole liver volume and right lobes volumes include middle hepatic vein (MHV)and exclude MHV,respectively.Secondly,the same data was transferred to Argus software.calculated that three volumes.Each measurement time was recorded.Actual graft volume(the right lobe)wag measured during surgery.The correlation between right lobes volume of two measurements and actual graft volume was analyzed.The time needed for Argus and that needed for manual method were compared with paired t test.Results The right lobe volumes measured by Argus,manually and surgery method were (813±187),(807 ± 181)and(713 ± 137)mm3,respectively.Argus method and manual method showed good correlation with surgery method,and the correlation coefficients were 0.897(Argus method)and 0.884(manual method),respectively.The time for manual method and Argu8 method were(44.3 ±2.7)and(12.2.±1.0)min,respectively.There was significant difference between Argus and manual methods (t=76.39,P＜0.05).Conclusion Compared with manual method,use of the Liver volumetric measurement by Argus software not only correlated well with Actual graft volume,but also saves time.Argus has potential clinical value for volumetric measurement in living liver transplant donors.

Objective To explore the risk factors,the distribution of etiology and drug resistance status of patients with early infection (3 months) after liver transplantation,and to provide reference for clinical diagnosis and treatment.Methods The clinical data of 112 recipients from February 2014 to December 2015 were collected,and logistic regression analysis was performed on the risk factors of early postoperative infection in liver transplant patients.The independent risk factors of infection after liver transplantation were screened out.At the same time,the results of pathogen culture and drug sensitivity test were statistically described.Results The independent risk factors for infection at 3th month after liver transplantation included the operative time ≥600 min [P =0.003,odds ratio (OR) =9.996,95 ％ confidence interval (95 ％ CI),2.221-44.981],intensive care unit (ICU) ≥6 days (P =0.010,OR =6.306,95％ CI =1.563-25.437),Child-Pugh grade of C (P =0.023,OR =6.298,95％ CI =1.294-30.659).Of the 112 liver transplant recipients,59 had an infection (52.68％),and 168 stains of pathogens were isolated.The positive rate of the specimens was highest in sputum,followed by bile,ascites,drainage and catheter end,blood,deep vein catheter,middle urinary,pleural effusion and peripherally inserted central catheter (PICC).The detectable rate of gram-negative bacteria,gram-positive bacteria,fungi and viruses was 46.43％ (78 strains),29.76％ (50 strains),18.45％ (31 strains),and 5.36％ (9 strains) respectively.Infection occurred mainly within 1 month after surgery,accounting for about 80.36％ (135 strains),especially at 1st week after surgery,accounting for about 34.52％ (58 strains).Gram-positive bacteria had a higher drug resistance rate,including penicillins,macrolides,aminoglycosides,quinolones,linamides,etc.especially in the highest rate of Enterococcus faeciurr.Gram-negative bacteria were individualized based on the different strains of the bacteria,and they were relatively low in the resistance of the carbapene.Conclusion Infection is one of the most common complications after liver transplantation.To reduce the incidence of infection after liver transplantation,efforts should be made to shorten the duration of operation and ICU stay time,improve the basic nutritional status of recipients,and enhance monitoring of the recipient's infection after liver transplantation,to further increase the survival rate of postoperative liver transplantation recipients and improve the quality of life.

Objective:To investigate the clinical efficacy of laparoscopic adrenalectomy and traditional open adrenalectomy for adrenal tumors in children.Methods:In Department of Pediatric Surgery, Fujian Provincial Maternity and Children′s Hospital from June 2008 to June 2016, the clinical data of 31 pediatric adrenal tumors was retrospectively analyzed.According to different surgical methods, they were divided into traditional open adrenalectomy group and laparoscopic adrenalectomy group.Bleeding loss, operation duration, incision length, abdominal drainage time, postoperative hospital stay, postoperative complications and recurrence were compared between the 2 groups.Results:There was no significant difference in age, sex, weight, and tumor size between the 2 groups (all P>0.05). The intraoperative bleeding loss was (18.06±4.86) mL for open adrenalectomy group and (15.20±4.48) mL for laparoscopic adrenalectomy group, and there existed no significant difference in the amount of bleeding between the 2 groups( T=-1.702, P>0.05). The operation duration was (137.44±19.32) min for open adrenalectomy group versus (134.80±6.21) min for laparoscopic adrenalectomy group, and there was no significant difference in operation duration between the 2 groups ( T=-0.504, P>0.05). The length of incision was (7.94±1.34) cm for open adrenalectomy group versus (3.44±0.21) cm for laparoscopic adrenalectomy group, the length of incision in laparoscopic group was shorter than that in open adrenalectomy group.There was significant difference in the length of incision between the 2 groups ( T=-12.843, P<0.001). The hospitalization time was (9.63±2.55) d for open adrenalectomy group versus (7.20±1.37) d for laparoscopic adrenalectomy group, the hospitalization time in laparoscopic group was shorter than those in open adrenalectomy group.The difference of operation time between the 2 groups was statistically significant ( T=-3.261, P=0.003). The average indwelling time of abdominal drainage tube was(5.94±1.53) d for open adrenalectomy group versus (4.80±1.74) d for laparoscopic adrenalectomy group, with no significant difference in postoperative abdominal drainage time between the 2 groups( T=-1.938, P>0.05). There was 1 case of retroperitoneal hematoma in laparoscopic adrenalectomy group and 2 cases of complications in open adrenalectomy group.There was no significant difference in the incidence of complications between the 2 groups ( P=1.000). There were 3 cases of distant metastasis and 1 case of recurrence in laparoscopic group, and 2 cases of distant metastasis and 1 case of recurrence in open adrenalectomy group.There was no significant difference in recurrence between the 2 groups ( P=1.000). Conclusions:Compared with open adrenalectomy surgery, laparoscopic adrenalectomy in children has various advantages, including beautiful incision, less trauma and fast recovery.However, it is necessary to select the appropriate cases.

Objective ::To investigate the role of trehalose in hepatic ischemia-reperfusion injury and its underlying mechanisms.Methods:C57BL/6J mice were randomly divided into no-ischemia group, ischemia-reperfusion group, trehalose-treated group and normal saline control group. After ischemia for 90 minutes, reperfusion immediately or 6h, blood and liver tissues were collected, and serum was separated. The liver function parameters of ALT, AST, the inflammatory factors of TNF-α, IL-1β and IL-2, and the pathological changes of liver were detected to study the role of trehalose during hepatic ischemia-reperfusion injury. Hypoxia-reoxygenation cell model was established by AML12 mouse hepatocyte line, and divided into experimental group and control group. The experimental group was divided into low dose group and high dose group according to the concentration of trehalose administrated. And the control group had no use of trehalose. The level of apoptosis was measured to study the effect of trehalose on apoptosis induced by hepatic ischemia-reperfusion injury with flow cytometry. Western blot was utilized for detecting the levels of Caspase-3, Cleaved Caspase-3 and Bcl-2 protein to understand the molecular mechanisms of trehalose in apoptosis during hepatic ischemia-reperfusion injury.Results:In vivo animal experiments showed that liver function and such inflammatory factors as ALT, AST, TNF-α, IL-1β and IL-2 increased in ischemia-reperfusion group after hepatic ischemia-reperfusion ( P<0.05), and liver tissue became necrotic. After a treatment of trehalose, the levels of ALT, AST, TNF-α, IL-1β and IL-2 were lower than those of normalsaline control group and the area of liver tissue necrosis also decreased ( P<0.05). In vitro cell experiments showed that the apoptosis level of hepatocytes in the experimental group decreased compared with the control group.And the level of activated pro-apoptotic protein Cleaved Caspase-3 decreased, the level of anti-apoptotic protein Bcl-2 increased. Conclusions:Trehalose has protective effects on hepatic ischemia-reperfusion injury in vivo and in vitro. The mechanism may be involved in inhibiting inflammation induced by hepatic ischemia-reperfusion injury, suppressing the activation of Caspase-3 and promoting the expression of Bcl-2, thus played a protective role by extenuation of hepatocyteapoptosis.

OBJECTIVEThis paper explores the relationships between mental health status of the patients' parents, whose children have cleft lip and palate, and their social impact factors.

METHODSThe 12-item general health questionnaire (GHQ-12) and the social support rating scale were used to conduct a questionnaire survey of 59 patients' parents. A data statistical analysis was done by using SPSS 13.0 software and Excel 2007 software.

RESULTS1)The mental health status of the patients' parents was in the middle level. 2) The mental health status of the patients' parents was related with the basic personal situations. It was apparently influenced by the qualifications and subjective state of mind. 3) The structure and relationship of the interpersonal networks of the patients' parents were the major constraint factors on the mental health status. 4) The social support degree and mental health status were positively correlated.

CONCLUSIONThe social network and social support have important influences on the mental health status of the parents whose children have cleft lip and palate. It should create a more harmonious and tolerant social environment.

Objective To analyze the law of the mid﹣term hepatic hemodynamics after liver transplantation and to investigate its relationship with liver function. Methods A total of 56 recipients underwent liver transplantation in the Affiliated Hospital of Qingdao University from February 2014 to October 2015 were studied,and divided into normal group (n =24)and abnormal group (n =32)according to the liver function.General information and liver function of both groups were recorded.Furthermore,hepatic artery peak velocity (HAP),portal vein peak velocity (PVP)and portal vein flow (PVF)before the liver transplantation and on postoperative day 1,30 and 90 were measured through ultrasonic detection;hepatic arterial buffer capacity (BC)and adjustment BC were calculated.The univariable and multivariable analysis were performed to analyze the relationship between hepatic hemodynamics and liver function in two groups,and the receiver operating curve (ROC)was drawn. Results The PVP and PVF on postoperative day 30 in abnormal group were significantly higher than those of normal group (P =0.014,0.049).The BC and adjustment BC in normal group were significantly higher than those of abnormal group (P =0.048,0.011).The multivariable analysis showed that adjustment BC was the independent risk factor (P =0.047),with the area under the curve (AUC)of ROC of 0.705,sensitivity of 0.652 and specificity of 0.750. Conclusions PVP,PVF,BC and adjustment BC on postoperative day 30 may be related to abnormal liver function,of which adjustment BC can be used as one of the indicators for diagnosis and intervention of abnormal liver function.

Objective To investigate the application value of contrast enhanced ultrasound (CEUS) for postoperative monitoring after split liver transplantation. Methods Ten recipients undergoing split liver transplantation received conventional two-dimensional ultrasonography, color Doppler ultrasound (CDU) and CEUS. Clinical prognosis of 10 recipients undergoing split liver transplantation was summarized. The findings of postoperative conventional two-dimensional ultrasonography, CDU and CEUS were analyzed. Results Among 10 recipients, 8 cases obtained favorable clinical prognosis, one died from the recurrence and metastasis of malignant tumors and multiple organ failure, and one died from sudden cardiac arrest. CDU detected the hepatic artery in 8 of 10 recipients(80%). CEUS revealed hepatic artery embolism in one recipient and normal hepatic artery in the other case. Conventional two-dimensional ultrasonography demonstrated abnormality of the hepatic parenchyma in 5 recipients including hyperecho in S5 segment in 1 case, hypoecho in S7 segment in 1 case, hyperecho in S4 segment in 1 case, hypoecho followed by hyperecho in S5 and S6 segments in 1 case and multiple hypoecho and slight hyperecho in 1 case. CEUS revealed significant asynchrony in the microcirculation blood perfusion between the normal and abnormal echo regions, manifested with imaging features of early perfusion and early regression, which was considered to be associated with hepatic venous back-flow obstruction. Evident asynchrony in microcirculation blood perfusion between the normal and abnormal echo regions was observed in 1 case, manifested with the imaging features of early perfusion and synchronous regression,suggesting that congestion and edema on the hepatic resection surface caused by hepatic venous back-flow obstruction and myocardial infarction. Multiple intrahepatic abnormal blood perfusion region of 'fast-in and fast-out' echo was noted in 1 case, which was probably correlated with postoperative recurrence of malignant tumors. Conclusions CEUS is an effective supplement of conventional two-dimensional ultrasonography and CDU for postoperative monitoring after split liver transplantation, which contributes to understanding of hepatic blood flow and blood perfusion and identifying early postoperative complications after split liver transplantation.
