This study was aimed to observe the influence of water-solubility nipponica saponin on activation of TNF-α+IL-17-induced rat fibroblast-like synovial cell line RSC-364 cellular model nuclear transcription factor NF-κB pathway as well as TNF-α, IL-1, ICAM-1, MMP-2, MMP-3 secretion. IL-17+ TNF-α were used for stimulating RSC-364 to establish rheumatoid arthritis (RA) cellular model. Water-solubility nipponica saponin in different con-centrations was used for intervention. The influence of water-solubility nipponica saponin in different concentrations on cell viability was detected by semi-quantitative RT-PCR method. Changes in the level of TNF-α, IL-1, ICAM-1, MMP-2, and MMP-3 of culture supernatant were detected by ELISA. The results showed that the activation of NF-κB p65 in RSC-364 stimulated by TNF-α+ IL-17 can be inhibited by water-solubility nipponica saponin ac-cording to its concentration. It improved IκB-α expression, and inhibited TNF-α, IL-1, ICAM-1, MMP-2 and MMP-3 secretion. It was concluded that water-solubility nipponica saponin can inhibit the activation of NF-κB pathway, hinder the secretion and activation of multiple downstream genes, which may be its effect in inhibiting syn-ovial inflammation in RA.

Chinese Journal of Gastrointestinal Surgery 2015;18(11):1128-1131
OBJECTIVETo explore the clinicopathological factors affecting positive cells in peritoneal lavage of gastric carcinoma.
METHODSClinicopathological data of 163 patients undergoing radical operation for gastric carcinoma and receiving cytology examination of peritoneal lavage (1000 ml normal saline) in our department from June 2013 to May 2014 were analyzed retrospectively. Pathology and immunohistochemistry were performed for resected lesions and harvested lymph nodes. Affecting factors of peritoneal lavage cytology were evaluated with univariate and multivariate logistic analyses.
RESULTSThe positive rate of exfoliative carcinoma cells was 9.2%(15/163). Univariate analysis showed that pathologic staging, depth of invasion, N staging, lymph node metastasis, station of positive lymph node, metastatic rate of lymph node, metastatic rate of the second station of lymph node, and carcinoma differentiation degree were associated with the positive rate of peritoneal lavage cytology (all P<0.05). Multivariate analysis revealed only the metastatic rate of the second station of lymph node was independent risk factor of positive exfoliative cells in peritoneal lavage.
CONCLUSIONThe metastatic rate of the second station of lymph node is an independent risk factor of positive exfoliative cells in peritoneal lavage for gastric cancer patients.

PURPOSE: Fibrinogen and platelets have been reported to play important roles in tumorigenesis and cancer progression. The aim of this research was to investigate the combination of functions of fibrinogen, platelets, and mean platelet volume (MPV) in predicting the survival of patients with gastric cancer (GC). MATERIALS AND METHODS: A retrospective study was conducted with 1,946 patients with GC and 299 patients with benign gastric tumor to analyze their fibrinogen, platelet, and MPV levels, and other clinicopathological characteristics along with their prognoses. Several indicators were evaluated along with fibrinogen, platelets, and MPV and their prognostic abilities were assessed. Univariate and multivariate survival analyses were conducted to determine the independent risk factors for overall survival. RESULTS: Increased levels of fibrinogen, platelets, and MPV were observed with the progress of the GC stages. Elevated fibrinogen, platelets, and the combined indicators, including fibrinogen*MPV (FM), platelet*fibrinogen*MPV (PFM), fibrinogen/MPV (FMR), platelet*fibrinogen (PF), platelet*fibrinogen/MPV (PFMR), platelet*MPV (PM), and platelet/MPV (PMR), foreboded poor prognosis. Meanwhile fibrinogen and FMR can be considered as independent risk factors for overall survival in patients with non-metastatic GC. But these indicators can hardly predict survival of patients in stage IV. CONCLUSIONS: Elevated fibrinogen, platelets, and MPV levels were in accordance with advanced stages, and fibrinogen, platelet, and MPV, in combination, can be used to predict survival of patients with non-metastatic GC. FMR was an independent prognostic factor for overall survival of patients with GC.

Objective To investigate the medium- and long-term effects and safty of Pipeline embolization device ( PED) for the treatment of large and giant intracranial anterior circulation aneurysms. Methods From December 2014 to December 2016,the data of 36 consecutive patients with large and giant aneurysm ( 36 large and giant intracranial anterior circulation aneurysms ) treated with PED in Donglei Brain Doctor Group were analyzed retrospectively. The diameter of the aneurysms was 12 -33 mm, (mean16.6±4.5mm),andthenecksizewas4-10mm(mean6.1±1.5mm).Eightaneurysmswere located in the carotid cavernous sinus segment,22 in the ophthalmic artery segment,5 in the internal carotid artery posterior communicating segment, and 1 in the M1 segment of middle cerebral artery. Seven aneurysms were only treated by PED,28 aneurysms were treated by PED in combination with coil embolization,and 1 aneurysm was treated by double PEDs. The modified Rankin scale ( mRS) score was used to evaluate the prognosis of the patients. Results (1) The clinical prognosis of the patients was followed up by telephone and outpatient department for 6-33 months. Twenty-five patients were followed up by DSA,23 aneurysms (92%) were occluded totally (Raymond gradeⅠ) and 2 (8%) were occluded near totally ( Raymond grade Ⅱ) . ( 2 ) Seven patients were treated with PED alone. Four patients were cured totally after 6 months follow-up,1 was occluded subtotally,2 were not cured;6 were cured in the last follow-up (33 months),and the other aneurysm was gradually reduced;17 of 28 patients treated with PED in combination with coils received DSA follow-up. They were followed up for 6-8 months. All the aneurysms were totally occluded ( Raymond grade Ⅰ) . 1 aneurysm was treated by 2 PEDs, DSA revealed micro-aneurysm-like development at 8 months after procedure. The aneurysms were basically occluded after 15-month follow-up. (3) MRI confirmed after operation that 10 patients had asymptomatic scattered spotted ischemic foci,4 had cerebral parenchymal hemorrhage,1 of them died,1 recovered well after treatment (mRS 1),and the other 2 were asymptomatic cerebral hemorrhage. The occupying effect of 24 cases disappeared, 8 had obvious improvement,and 3 did not have any obvious change. Conclusions The occlusion rate of the treatment of large and giant intracranial aneurysms with PED was high. The results of medium-term follow-up showed that the occlusion rate of PED in combination with coils in the treatment of aneurysms was higher than that of PED alone. The long-term follow-up results showed that the occlusion rate of patients treated with PED alone (including one or more) was gradually increased with time. The safety of the surgery needs to be further confirmed by a large sample study.

OBJECTIVETo investigate the relationship of prognostic nutritional index (PNI) with clinicopathological factors and the clinical significance of PNI in predicting the survival in patients with advanced gastric cancer.
METHODSClinicopathological and follow-up data of 1150 patients with advanced gastric cancer who underwent radical gastrectomy from January 2007 to December 2010 at the Department of Gastrointestinal Surgery, Harbin Medical University Cancer Hospital were analyzed retrospectively. The PNI value was calculated [PNI=absolute value of lymphocyte(10/L)×5 + serum albumin (g/L)] and was grouped according to the mean value of PNI. Relationships of PNI with gender, age, tumor size, depth of invasion, tumor differentiation, tumor stage, tumor location, lymph node metastasis and tumor marker detection level were analyzed. At the same time, for the survival analysis of patients, log-rank method was used for univariate analysis, and Cox method was used for multivariate analysis.
RESULTSOf 1150 cases, 846 were males and 304 were females with an average age of 62 (24 to 88) years. The average maximum diameter of tumor was 5.4(1.0 to 20.0) cm. Tumor of 159 cases located in the gastric fundus, 221 cases in the gastric body, 705 cases in the gastric antrum and 65 cases in the whole stomach. Well differentiated tumors were found in 198 cases and poorly differentiated tumors in 952 cases. As for depth of tumor invasion, 165 cases were T2, 343 cases were T3 and 642 cases were T4. According to TNM stage, 53 cases were stage I(, 397 cases were stage II( and 700 cases were stage III(. The average lymph node metastasis rate was 25.0%, meanwhile lymph node metastasis was N0 in 296 cases, N1 in 246 cases, N2 in 277 cases and N3 in 331 cases. Blood examination showed hemoglobin ≤130 g/L in 544 cases and >130 g/L in 606 cases; carcinoembryonic antigen ≤5 μg/L in 903 cases and >5 μg /L in 247 cases; carbohydrate antigen 19-9 ≤37 kU/L in 927 cases and >37 kU/L in 223 cases. In whole patients, the mean value of PNI was 51.81(24.5 to 80.4), PNI ≤51.81 group had 563 cases, and PNI >51.81 group had 587 cases. Between PNI ≤51.81 group and PNI >51.81 group, age (χ=22.661, P=0.000), tumor location (χ=8.979, P=0.030), tumor size (χ=34.509, P=0.000), tumor stage (χ=11.644, P=0.003), depth of tumor invasion (χ=21.681, P=0.000) and hemoglobin (χ=112.262, P=0.000) were significantly different. Patients were followed up for an average of 45.1 months (4 to 108). The 5-year survival rate was 37.7% in PNI ≤51.81 group, while it was 47.0% in PNI >51.81 group, whose difference was statistically significant (χ=8.326, P=0.004). Univariate analysis showed that patients with PNI ≤51.81(P=0.004), deeper tumor invasion (P=0.000), more metastatic lymph nodes (P=0.000), later TNM stage (P=0.000), lymph node metastasis rate >25.02%(P=0.000), hemoglobin ≤130 g/L(P=0.011), the maximum tumor diameter >5.4 cm (P=0.000), tumor undifferentiated (P=0.001), CEA >5 μg /L (P=0.000), CA199 >37 kU/L(P=0.000) and tumors locating in whole stomach (P=0.000) had poorer prognosis. Multivariate analysis showed that the age (HR=1.195, 95%CI: 1.019 to 1.401, P=0.028), the depth of tumor invasion(HR=1.429, 95%CI: 1.231 to 1.658, P=0.000), the number of metastatic lymph node (HR=1.536, 95%CI:1.330 to 1.774, P=0.000), the lymph node metastasis rate (HR=1.376, 95%CI:1.102 to 1.717, P=0.005), tumor TNM stage (HR=1.387, 95%CI: 1.026 to 1.876, P=0.033) and tumor size(HR=1.182, 95%CI: 1.005 to 1.390, P=0.043) were independent prognostic factors of gastric cancer patients, while PNI (HR=0.913, 95%CI: 0.774 to 1.076, P=0.278) was not an independent risk prognostic factor of gastric cancer patients.
CONCLUSIONSAlthough the PNI is not an independent risk factor of overall survival in patients with advanced gastric cancer, it is still an indicator of survival in patients with gastric cancer. Improving preoperative nutritional status in patients with gastric cancer may contribute to a better prognosis.
