Objective To study the impact of diabetes mellitus (DM) and postoperative blood glucose control on the clinicopathological characteristics and prognosis of patients with pancreatic cancer who underwent radical surgery.Methods From January 2010 to January 2015, the clinical and follow-up data of 83 patients with pancreatic cancer who underwent radical surgery at Tianjin Medical University General Hospital were retrospectively studied.Patients were classified into the diabetic group (28 cases) and the non-diabetic group (55 cases) according to the preoperative status of DM.The clinicopathological characteristics, postoperative conditions and prognosis were compared.Results The incidences in the two groups of patients whose postoperative blood glucose levels were poorly controlled were 71.4％ (20/28) and 20.0％ (11/55) in the diabetes group and the non-diabetic groups, respectively.The difference was significant (P ＜0.05).The 3-year survival rate of the diabetic and the non-diabetic groups were 11.3％ and 31.8％ , respectively.The difference was significant (P ＜ 0.05).The 3-year survival rate of patients with poorly-controlled blood glucose levels were 8.8％, and 34.6％, respectively.The difference was significant (P ＜ 0.05).Conclusions The postoperative blood glucose level in pancreatic cancer patients with DM was poorly controlled after radical surgery.The prognosis of pancreatic cancer patients with DM or poorly postoperative blood glucose control was poor after radical surgery.

Objective To explore the clinical value of serological indicators in diagnosis of patients with different degree of liver cirrhosis.Methods 50 patients with liver cirrhosis and 50 patients with decompensate cirrhosis were selected.The control group had 50 patients.The serological indicators were statistically analyzed.Results TBIL and ALT in the decompensated liver cirrhosis group were (69.5 ± 7.0) μmol/L,(143.1 ± 14.2) U/L,which were higher than those of compensated liver cirrhosis group (44.6 ± 5.8) μmol/L,(77.4 ± 8.6) U/L (P ＜ 0.05),and those two groups were higher than the control group(P ＜ 0.05).Alb and ChE of decompensated liver cirrhosis group were (28.2 ± 3.7) g/L and (2024.39 ± 211.40) U/L,which were lower than those of the control group (36.1 ±3.7) g/L,(6169.36 ± 607.42) U/L and the compensated cirrhosis group [(34.7 ± 4.3) g/L,(3571.27 ± 310.01)U/L] (P ＜0.05).ChE of compensated cirrhosis group was lower than the control group (P ＜0.05).PA and ADA of decompensated and compensated liver cirrhosis group were (0.14 ±0.04)mg/L,(16.17 ± 1.94)U/L and (0.21 ±0.05) mg/L,(34.20 ± 3.29) U/L,the differences were statistically significant (P ＜ 0.05).A/G of decompensated and compensated liver cirrhosis group were (0.64 ± 0.29) and (1.06 ± 0.30),which were lower than the control group (1.51 ± 0.21) (P ＜ 0.05),and that of the decompensated cirrhosis group was lower than that of the compensated cirrhosis group(P ＜0.05).Ⅳ-C and LN of decompensated cirrhosis group were (97.4 ±9.8) μg/L and (205.7 ±20.1) μg/L,which were higher than those of compensated liver cirrhosis group (68.7 ± 7.5) μg/L and (124.1 ±11.8) μg/L and the control group(52.3 ±6.1) μg/L and (83.8 ±7.6) μg/L(P ＜0.05).And those of the compensated cirrhosis group were higher than the control group (P ＜ 0.05).HA and PC Ⅲ of decompensated cirrhosis group were (211.3 ± 16.4) μg/L and (168.1 ± 16.2) μg/L,which were higher than the control group (51.2 ±5.3) μg/Land (79.1 ± 8.0) μg/L (P ＜ 0.05).Conclusion The serological indicators had the important reference value for clinical diagnosis and prognosis of cirrhosis.

Objective To study the effect of Radix Salviae Miltiorrhizae (RSM), a kind of Chinese Traditional Medicine which can dissolve stasis by activating blood circulation, on proliferation, invasion, adhesion, migration and metastasis of B16-BL6 metastatic mouse melanoma cells and discuss its functional mechanism. Methods The proliferation, adhesion, invasion and migration capacity of B16-BL6 metastatic cells was evaluated by MTT assay, adhesion assay and reconstituted basement membrane invasion and migration assay in vitro respectively. Mouse spontaneous melanoma model was used to study the effect of RSM on metastasis in vivo. Results The extract of RSM bidirectionally adjusted the multiplication of B16-BL6 cells, promoted prominently the adhesion of B16-BL6 to Laminin, inhibited significantly B16-BL6 invading reconstituted basement membrane and the migration of B16-BL6. In the mouse spontaneous melanoma model, it suppressed significantly the volume of lung metastatic nodes but had little effect on the number of lung metastatic nodes. Conclusion The extract of RSM can alleviate the degree of the metastasis of B16-BL6 metastatic mouse melanoma cells, which may be related with inhibiting the B16-BL6 cells invading the extracellular matrix and reducing the migration of B16-BL6 cells.

Objective To evaluate the expression of Yes-associated protein (YAP) in colorectal carcinoma and analyze its influence on tumor cell proliferation.Methods The expressions of YAP in 94paired colorectal carcinomas and pericancerous normal tissues were detected by using immunohistochemistry method.The expressions of YAP in colorectal carcinoma cell line HCT116 were inhibited with a YAP-spe-cific siRNA.Cell proliferation was then determined by methyl thiazolyl diphenyl-tetrazolium bromide (MTT) assay.Results The positive rate of YAP in colorectal carcinomas was significantly higher than that in pericancerous normal tissues [69.1％ (65/94) vs 22.3 ％ (21/94),P ＜ 0.001].The expression of YAP was associated with tumor Node Metastasis(TNM) stage and lymph node metastasis(P ＜0.05),but not associated with gender,age,tumor location and histological grade(P ＞0.05).After YAP-specific siR-NA was transfected into HCT116 using lipofectamine,the expression of YAP mRNA and protein in the experimental group were reduced by (78.2 ±2.1)％ and (81.7 ± 1.5)％,respectively,with a statistically significant difference (t =67.55,91.601,P ＜0.01).The growth of HCT116 was significantly inhibited and the reduced rate of cell proliferation was (28.1 ± 1.6) ％,(34.7 ± 2.4) ％ and (24.7 ± 1.2) ％ at the time point of 48 h,72 h and 96 h,respectively.Conclusions Expression of YAP was upregulated in colorectal carcinomas and downregulation of YAP expression could inhibit growth of colorectal carcinoma cells.YAP can be used as a new candidate target for diagnosis and treatment of a colorectal carcinoma.

Background and purpose:Stromal tumor is one of the common gastrointestinal mesenchymal tumors. There is certain understanding about the typical cases. However, the diagnosis of those occurring in rare location or with rare imaging findings is often difficult. This research summarized this kind of cases,in order to increase the radiological knowledge of the disease.Methods:This study retrospectively analyzed clinical, radiological and pathological data from 550 patients who had stromal tumor conifrmed by pathology in our hospital. Those with incomplete data were eliminated. Forty-nine patients were selected for further study according to the typical imaging findings.Results:Among these 49 patients, 9 were pathologically confirmed to have extra-gastrointestinal stromal tumor, while 40 patients had gastrointestinal stromal tumor. Among the patients with gastrointestinal stromal tumor, 22 were found in rare locations, 12 in retroperitoneal space, 3 in omentum majus and mesenterium, 5 in esophagus, and 2 in prostate. Obvious cystic degeneration was found in 16 patients. Bulky calciifcation, such as lfake or annulus, was found in 7 patients. The analysis result of risk-stratiifcation showed 19 patients were conifrmed as high-grade among the patients with tumors found in rare locations, 15 as high grade among those with obvious cystic degeneration, and 7 as high-grade among those with extra-gastrointestinal stromal tumor.Conclusion:Rare stromal tumor often occurs in the locations, such as retroperitoneal space, omentum majus and mesenterium. Obvious cystic degeneration and bulky calciifcation can be seen. The risk-stratiifcation of these patients often showed high-grade. Comprehensively analyzing its clinical features and imaging ifndings can help improve the diagnostic accuracy.

Objective To discuss the perioperative nursing for patients with Laparoscopic resection of gastrointestinal stromal tumors. Methods A retrospective study was carried out in 18 patients with gastrointestinal stromal tumors on the effect of perioperative nursing and surgery. Results The gastrointestinal stromal tumors were resected under Laparoscopy with average operation time of 70 minutes. Blood loss volume during the operation was 20 to 50 ml. All patients recovered well with hospitalization days of 4 to 9 days. No relapse or metastasis was seen after 6 to 22 months of follow-up visit. Conclusions Laparoscopic resection of gastrointestinal stromal tumors was safe and effective. Perioperative nursing had significant effect on the recovery of patients.

AIM: To study the in situ stimulation effect of compound aluminum sulfate injection after i.m. in rabbit quadriceps and dog bladder. The absorption of aluminum and the healing of the bladder wall were also studied to give an evaluation on the safety of the compound injection. METHODS: Compound aluminum sulfate injection was i.m. injected into quadriceps of the rabbits. The in situ stimulation effect was observed macrographically. Blood samples were collected at different time after i.m. injection. Aluminum concentrations were determined by ICP-MS assay and simulated with DAS software. Tissue necrosis as well as the healing of the bladder wall were observed macrographically or pathologically after the injection was given into dog bladder. RESULTS:Severe stimulation was observed after intra quadriceps injection, however, there was no obvious elevation of blood aluminum concentration. The average AUC0-24 was 2.93±1.82 mg·h·L-1 (n=5), corresponding to a relative bioavailability of about 2.77%. Injecting in bladder muscle necrotized the bladder wall in situ, but fibroblast generated and took place of the necrotized membrane and muscle four weeks after injection. There was no bleeding or perforation on the bladder wall. CONCLUSION:Caused compound aluminum sulfate injection in situ necrosis which healed up in 4 weeks. Aluminum absorption is very low after injection, giving a further explanation to the safety of the compound injection.
