ABSTRACT

Background and purpose: Ovarian lymphoma (OL) is usually misdiagnosed as ovarian cancer with bulk lymph node invasion (OC-BLN), and vice versa. Therefore, to distinguish these two types of disease, we compared their clinical characteristics in this study. Methods: This study retrospectively reviewed 14 OL and 14 OC-BLN patients from Fudan University Shanghai Cancer Center and Shanghai Eighth People's Hospital. The clinical char-acteristics, image and laboratory examination data were compared. Results: There was no significant difference in age, symptom, fever, weight loss and volume of ascitic fluid between the two groups. Comparing with OC-BLN, OL patients have larger tumor in ovaries [(13.04±5.94) cm vs (7.78±6.38) cm, P=0.033], and higher percentage of solid ovarian tumor (85.71% vs 28.5%, P=0.006). Lactate dehydrogenase(LDH)/CA125 was higher in OL (7.66±8.03) than OC-BLN (0.31±0.27, P=0.009). Using LDH/CA125 to diagnose OL, area under the curve (AUC) was 0.952. When the threshold value was set at 1, the sensitivity and specificity was 91.7% and 100%, respectively. Conclusion: OL and OC-BLN are easily to be misdiagnosed. OL has larger and more solid tumor than OC-BLN. LDH/CA125 can help to distinguish these two diseases and guide clinical decision making.

ABSTRACT

T cell immune checkpoint pathways contribute to tumor immune escape. Many studies have shown that immune checkpoint is demonstrably correlated with tumor grade or prognosis in several types of malignancies and immune checkpoint has become a new biological index for tumor detection and prognosis. Immune checkpoint inhibitors have shown promising tumor outcomes in clinical trials for some advanced solid tumors and it will become a new target for cancer immunotherapy. In this review we will explore the correlation between expressions of immune checkpoint-associated genes and proteins in immune microenviroment and prognosis of head and neck squamous cell carcinoma, and specifically will discuss how this pathway can be manipulated with immune therapeutic drugs.

ABSTRACT

The relationship between Kruppel-like factor 4 (KLF4) and the Notch pathway was determined to investigate the effect of KLF4 on the activation of hepatic stellate cells and underlying mechanisms. Fifty SPF BALB/c mice were randomly divided into two groups. A liver fibrosis model was established in 25 mice as the experimental group, and the remaining 25 mice served as controls. On the day 0, 7, 14, and 35, liver tissues were removed for immunofluorescent detection. The Notch pathway inhibitor DAPT was added to the primary original hepatic stellate cells, and KLF4 and Notch-associated factor expression was detected by qRT-PCR. Additionally, the hepatic stellate cell line LX-2 was used to establish control and experimental groups, and was cultured in vitro. LX-2 cells in the experimental groups were treated with DAPT and the Notch activator transforming growth factor-beta 1 separately, whereas those in the control group were given isotonic culture medium. After 48 h, KLF4 expression was examined by Western blotting. After transient transfection of LX-2 cells to increase KLF4, the expression of Notch factor was examined. Immunofluorescence analysis showed that, with the aggravation of liver fibrosis, the absorbance (A) values of KLF4 were decreased (day 0: 980.73±153.19; day 7: 1087.99±230.23; day 14: 390.95±93.56; day 35: 245.99±87.34). The expression of Notch pathway- related factors (Notch-1, Notch-2, and Jagged-1) in the hepatic stellate cell membrane was negatively correlated to KLF4 expression. With the increase of KLF4 expression, Notch-2 (0.73±0.13) and Jagged-1 (0.43±0.12) expression decreased, whereas Notch-1 level was not detectable. When the Notch pathway was inhibited, KLF4 levels generally increased (18.12±1.31). Our results indicate that KLF4 expression is negatively correlated to the Notch pathway in hepatic stellate cells, which may provide a reference for the treatment of hepatic fibrosis.

ABSTRACT

<p><b>OBJECTIVE</b>The aim of this study was to compare the safety and efficacy profiles of R-CHOP and R-fCHOP regimes in the treatment of primary gastric diffuse large B cell lymphoma (PG-DLBCL).</p><p><b>METHODS</b>Data of PG-DLBCL patients admitted in our hospital from March 2010 to March 2014 were collected retrospectively. Differences in gastrointestinal bleeding and perforation between the R-CHOP group and R-fCHOP group were compared. The influence of the gastrointestinal complication on subsequent treatment was also analyzed. Treatment outcome of the two groups was also compared.</p><p><b>RESULTS</b>A total of 50 patients were included in this retrospective study. Forty of them were in the R-CHOP group, another ten were in the R-fCHOP group. Patients in the R-fCHOP group had a higher rate of Lugano late stage disease, and a relatively high rate of a deeper/larger ulcer. Fence occult blood test (FOBT) was positive in one (10.0%) patient in the R-fCHOP group, and 11 (31.4%) patients in the R-CHOP group, among them one had hematemesis and had to give up the subsequent chemotherapy. No perforation was observed in both groups. The response rate (RR) was 92.5% in the R-CHOP group and 90.0% in the R-fCHOP group (P > 0.05). The PFS was also comparable between the two groups (P > 0.05).</p><p><b>CONCLUSIONS</b>R-fCHOP regimen has a good safety profile in patients with Lugano late stage and deep/large ulcers, who are of high risk of gastrointestinal bleeding or perforation, and also has a comparable efficacy profile when compared with the R-CHOP regimen in short-term follow-up.</p>

ABSTRACT

Objective To explore the application of B-mode intra- and post-operative ultrasound in patients with traumatic brain injuries. Methods B-mode intra- and post-operative ultrasound were performed 35 times in 24 patients, including 7 times of intra-operation in 7 patients and 28 times of post-operation in 17 patients. Results During operation epidural hematomas in 3 cases as well as intracranial hematomas in 2 cases, subdural hematomas in 1 case, diffused brain swelling in 1 case were found. After operation epidural hematomas were examined in 4 cases as well as subdural hematomas in 1 case, delayed intracranial hematomas in 6 cases, scattered contusion and laceration of the brain in 12 cases, acute obstructive hydrocephalus in 1 case, and subdural hydroma in 4 cases. Six cases underwent operations again because of delayed hematomas, contusion and laceration of the brain. B-mode ultrasound was compared with CT scan and the total coincidence rate was 85.4%.Conclusions B-mode ultrasound is helpful to examine delayed hematomas and other emergent complications. It may save time and may improve rescue rate and has a good coincidence with CT scan. B-mode ultrasound may be widely used as a routine way in neurotrauma ICU.
