Objective:To investigate the clinical value of serological test indicators in the identification of primary and metastatic liver cancers. Methods:We detected the serum levels of ALT, AST, ALP, TBIL, DBIL, GGT, CHE, 5'-NT, CA199, CEA, and AFP in primary hepatic carcinoma (PHC;120 cases), metastatic hepatic carcinoma (MHC;135 cases), and no liver metastatic control (135 cas-es) groups. The methods used were variance analysis and Scheffe test. ROC curve analysis was used to determine the diagnostic value of CA199 , CEA, and AFP in PHC and MHC. Results:The difference between the serum levels of AST, ALP, GGT, 5'-NT, AFP, and CEA of the PHC and MHC groups was statistically significant (P<0.05). The AFP, CEA, and CA199 areas under the ROC curve of the PHC and MHC groups revealed that AFP diagnosis of primary liver cancer had certain accuracy, whereas CEA and CA199 have some diagnostic value in differentiating primary and metastatic liver cancers. Conclusion: The detection of serum levels of AST, GGT, 5'-NT, AFP, CA199, and CEA in malignant tumor was a preliminary diagnosis of liver metastasis and can provide evidence for the dif-ferential diagnosis of PHC and MHC.

Objective To investigate the clinical outcomes of radical surgery for pancreatic body and tail tumors accompanied with sinistral portal hypertension (SPH).Method The clinicopathological data of 35 patients with pancreatic body and tail tumors accompanied with SPH operated from January 2004 to December 2014 were retrospectively analyzed.Results Of 35 patients,22 patients had body and tail pancreatic carcinomas,10 patients had malignant solid pesudopaillary tumors and 1 patients had a neuroendocrine tumor.All these patients developed splenomegaly and varices in the gastric fundus with normal hepatic function.The splenic vein pressure was (27.3 ±3.8)cmH2O (1 cmH2O =0.098 kPa),its average diameter was (1.3 ± 0.3) cm,and the speed of splenic vein blood flow was (8.9 ± 0.8) cm/s.Of the 35 patients with pancreatic body and tail tumors who underwent radical resectional operations,22 patients in addition underwent devascularization.There were 13 of these 22 patients who underwent pericardical devascularization and the remaining 9 underwent total or proximal gastrectomy.The main complications were pancreatic fistula (n =5,14.2％),intra-abdominal infection (n =4,11.5％),delayed gastric emptying (n =1,2.8％),lymphatic fistula (n =1,2.8％) and gastric perforation (n =1,2.8％).The post-complication morbidity rate was 34％.All these patients were followed-up for 6 to 60 months after operations.There was no upper gastrointestinal bleeding which occurred within 6 months of operation.Conclusion Multi-disciplinary treatment,complete preoperative evaluation,correct perioperative and individualized management enhanced efficacy in the surgical treatment of patients with pancreatic body and tail tumors with SPH.

OBJECTIVE:To observe the clinical efficacy and transdermal absorption of Suhong bone-penetrating massage drug for rheumatic arthralgia. METHODS:Suhong bone-penetrating massage drug(Chinese medicine) was applied in 300 cases with rheumatic arthralgia characterized by various symptoms such as bone spur, injury, scapulohumeral periarthritis, acute injury or chronic strain of articular surrounding soft tissue; Suhongtougu powder was used as control to treat another 120 cases with the same disease. The curative efficacies in two groups were compared. The effects of the effective components such as Muskone,Borneo Camphor,Menthol in Suhong bone-penetrating massage drug on the transdermal absorption of this preparation was investigated by transdermal test on mice. RESULTS:The total effective rate in the treatment group was 93.24% as compared with 80.00% in the control group, showing significant difference between two groups(P

6 hours). The APACHE Ⅱ and POSSUM scoring system during perioperative period was in positive correlation with postoperative morbidity and mortality. Conclusions Pancreatoduodenectomy for the treatment of periampullary carcinomas is with high risks. Postoperative mortality and morbidity were in close correlation with the risk factors.

Objective To study the surgical treatment of the primary retroperitioneal sarcoma(RPS). Methods The treatment and prognosis of 63 patients with primary retroperitoneal sarcomas (liposarcomas and leiomyosarcomas) from Jan 1992 to Dec 2000 were analyzed retrospectively. Results The rate of complete tumor resection was 88.2%, and concomitant resection of involved adjacent organs was 21.6%. There was no operation death. The median survival time(MST) in liposarcomas that for was 36.5months, and leiomyosarcomas was 27.6 months. The MST in highly differentiated tumor was 34.7 months,and that of intermiade and low differtiated tumors was 18.1months(P

Objective To analyze the association of staphylococcal nuclease domain-containing protein 1(SND1) and T-cell intracellular antigen 1(TIA-1) on stress granules, and the regulation of SND1 on stress granules under stress stimuli. Methods The immunofluorescence assay and laser scanning confocal microscopy were used to observe the co-localization of SND1 protein and TIA-1 protein under stress stimuli, and the over-expression plasmids of pEGFP vector were transfected into HeLa cells and to verify which domain of SND1 co-localized with TIA-1 under stress stimuli. RNA interference-mediated knockdown of the expression of SND1 protein in HeLa cells was measured by Western Blotting assay. Then whether the knockdown of SND1 affected the recruitment of TIA-1 on stress granules was observed. Heat shocks under different times were used to identify whether there were dynamic changes in transportation of SND1 and TIA-1 on stress granules. Results SND1 co-localized with TIA-1 on stress granules under stress stimuli, and the associated domain of SND1 were SN domain. TIA-1 still can be recruited on stress granules but a large amount of stress granules were reduced even though the expression of SND1 protein was decreased. And the transportation of SND1 on stress granules was laged behind TIA-1 under different-times of heat shocks. Conclusion SND1 protein co-localizes with TIA-1 on stress granules, and which co-regulates the cellular stress response under stress stimuli.

Aim To observe the optimal temperature and optimal pH of uricase-catalase liposomes(UCALP) and free uricase(UAE), and study the abilities of UCALP to reduce uric acid and hydrogen peroxide in mice with hyperuricemia.Methods UCALP were prepared by reverse phase evaporation, optimal temperature and optimal pH of UCALP and UAE were determined, respectively.Mouse model of hyperuricemia was established by intraperitoneally injection of uric acid, and the model mice were intravenously injected UCALP and UAE, respectively, then the serum concentration of uric acid and hydrogen peroxide in mice at different time points were measured by the assay kits, respectively.Results Optimal temperature of UCALP and UAE was 40℃, and optimal pH was 8.0 and 8.5, respectively.UCALP could more significantly lower uric acid level of hyperuricemia mice than that of UAE, and the concentration of hydrogen peroxide in UCALP group was lower than in UAE group.Conclusion UCALP can effectively decrease the level of uric acid and control the level of hydrogen peroxide in mice with hyperuricemia.

Objective To establish an LC-MS/MS method for the detection of landiolol concentration in human blood.Methods After pretreatment with neostigmine and a deproteinization procedure, landiolol and the internal standard venlafaxine were eluted isocratically using a mobile phase consisting of acetonitrile and 10 mmoL·L-1 ammonium acetate with 0. 1% formic acid in a ratio of 3664 ( V/V ) . Separation of the respective compounds was achieved on a Waters XTerra? RP18 column (150 mmí4. 6 mm,5 μm). Quantitative analysis of landiolol was conducted by a triple-quadrupole mass spectrometer with positive-electrospray ionization source,monitored under a multiple reaction monitoring ( MRM) mode. The extracted ions monitored following MRM transitions were m/z 510. 5→423. 1 for landiolol and m/z 278. 2→215. 1 for the internal standard venlafaxine. ResultsThe calibration curve of landiolol in human blood showed good linear relationship in the range of 1. 010-2 020 μg·L-1 . The lower limit of quantitation was 1. 010 μg · L-1 . The RSD of within-day and between-day precision was less than 6. 5% and 4. 8%, respectively. The recovery rate was 92. 6%-100. 9%. Conclusion The method is proven to be simple,rapid and reliable,and can be applied to study the pharmacokinetics of landiolol hydrochloride in healthy Chinese volunteers.
