Objective: This study aimed to investigate the effect of multimodality treatment of advanced paediatric hepatoblastoma (HB) and the factors affecting prognosis. Methods: A total of 35 children underwent multimodality treatments consisting of chemotherapy, surgery, interventional therapy, and autologous peripheral blood stem cell transplantation. The patients were followed up every month. Results: Serum AFP levels in 33 out of 35 patients in this study were significantly increased (P = 0.0002). According to the statistical scatter plot, the values of serum AFP on the 25th, 50th, and 75th percentages were 1,210, 1,210 and 28,318 ng/dl, respectively. Of the 35 cases, 21 were stage IV. 18 cases were treated with systemic chemotherapy before surgery, and 3 cases with locally interventional chemotherapy before surgery. Statistical analysis showed that the preferred interventional treatment affected prognosis, and that there was a statistically significant difference (P = 0.024). Some 33 patients completed the follow-up, of which 17 were in complete remission (CR), 5 were in partial remission (PR), 1 became disease progressive (DP), and 10 died. The remission and overall survival rates were 66.7% (22/33) and 69.7% (23/33), respectively. Patients with the mixed HB phenotypes had worse prognoses than the epithelial phenotype (P < 0.001), and patients in stage IV had a lower survival rate than those in stage III (P < 0.001). Conclusion: Multimodality treatment can effectively improve remission rate and prolong the survival of children with advanced HB. In addition, alpha-fetoprotein (AFP), a tumor marker of liver malignant tumors, HB pathological classification, and staging are highly useful in predicting prognosis.

Colorectal cancer has become the third most common cancerand leads to high mortality worldwide. Although colorectalcancer has been studied widely, the underlying molecularmechanism remains unclear. PER3 is related to tumordifferentiation and the progression of colorectal cancer. Highexpression of miR-103 is associated with poor prognosis inpatients with colorectal cancer. However, the relationshipbetween miR-103 and PER3 in CRC cells remains unclear. Inthis study, we found that PER3 was downregulated in CRC tissues and CRC cell lines, whereas miR-103 was upregulatedin CRC cell lines. We also found that PER3 promoted CRCcells apoptosis. These results indicate that PER3 plays asuppressive role in CRC cells. Moreover, we found that PER3was targeted, at least partially, by miR-103. Taken together, weprovide evidence to characterize the role of PER3 in CRC, which may be a new therapeutic target for CRC.

Sepsis is a systemic inflammatory responsesyndrome caused by severe infections. Astilbin is a dihydroflavonolderivative found in many medicinal and foodplants with multiple pharmacological functions. To investigatethe effects of astilbin on sepsis-induced acute lunginjury (ALI), cecal ligation and puncture was performed onrats to establish a sepsis-induced ALI model; these ratswere then treated with astilbin at different concentrations. Lung injury scores, including lung wet/dry ratio, proteinleakage, myeloperoxidase activity, and inflammatory cellinfiltration were determined to evaluate the effects ofastilbin on sepsis-induced ALI. We found that astilbintreatment significantly attenuates sepsis-induced lunginjury and improves survival rate, lung injury scores, lungwet/dry ratio, protein leakage, myeloperoxidase activity,and inflammatory cell infiltration. Astilbin treatment alsodramatically decreased the production of inflammatorycytokines and chemokines in bronchoalveolar lavage fluid. Further, astilbin treatment inhibited the expression andproduction of macrophage inhibitory factor (MIF), whichinhibits the inflammatory response. Collectively, these datasuggest that astilbin has a protective effect against sepsisinducedALI by inhibiting MIF-mediated inflammatoryresponses. This study provides a molecular basis for astilbinas a new medical treatment for sepsis-induced ALI.

Hua Zhang,Tao Liu,Yue Wang,Hai-feng Liu,Jian-tao Zhang,Yan-shuang Wu,Lei Lei,Hong-bin Wang 대한수의학회 2014 JOURNAL OF VETERINARY SCIENCE Vol.15 No.3

A purely laparoscopic four-port approach was created forleft hepatectomy in pigs. A polyethylene loop was placed onthe left two hepatic lobes for traction and lift. Next,penetrating ligation of the lobes using of a double row of silksutures was performed to control bleeding. A direct hepatictransection was completed using a monopolar hook electrodewithout meticulous dissection of the left hepatic vein. Theraw surface of the liver was coagulated and sealed with fibringlue. Lobes were retrieved through an enlarged portal. Laparoscopic hepatic lobectomy was completed in all pigswithout the use of specialized instruments and with a meanoperative time of 179 ± 9 min. No significant perioperativecomplications were observed. The average weight of eachresected lobe was 180 ± 51 g. Complete blood count as well asserum organics and enzyme levels normalized after about 2weeks. During necropsy, adhesion of the hepatic raw surfaceto the gastric wall and omentum were observed. No otherabnormalities were identified. This minimally invasive lefthepatectomy technique in swine could serve as a usefulmodel for investigating liver diseases and regeneration, andoffer preclinical information to improve hepatobiliary surgical procedures.

Wang, Xue-Jian,Duan, Yu,Li, Zong-Tao,Feng, Jin-Hong,Pan, Xiang-Po,Zhang, Xiu-Rong,Shi, Li-Hong,Zhang, Tao Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

Multi-target drug design, in which drugs are designed as single molecules to simultaneously modulate multiple physiological targets, is an important strategy in the field of drug discovery. QT-011, a tamibarotene-furoxan derivative, was here prepared and proposed to exert synergistic effects on antileukemia by releasing nitric oxide and tamibarotene. Compared with tamibarotene itself, QT-011 displayed stronger antiproliferative effects on U937 and HL-60 cells and was more effective evaluated in a nude mice U937 xenograft model in vivo. In addition, QT-011 could release nitric oxide which might contribute to the antiproliferative activity. Autodocking assays showed that QT-011 fits well with the hydrophobic pocket of retinoic acid receptors. Taken together, these results suggest that QT-011 might be a highly effective derivative of tamibarotene and a potential candidate compound as antileukemia agent.

Purpose: This systematic analysis was conducted to evaluate the efficacy and safety of pemetrexed based salvage chemotherapy for treatment of patients with metastatic colorectal cancer. Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for patients with colorectal cancer were identified using a predefined search strategy. Pooled response rates (RRs) were calculated. Results: For pemetrexed based regimens, 4 clinical studies including 201 patients with advanced colorectal cancer were considered eligible for inclusion. The analysis suggested that, in all patients, pooled RR was 20.4% (41/201). Major adverse effects were neutropenia, anorexia, fatigue, and anemia. No treatment related death occurred with pemetrexed based treatment. Conclusion: This systematic analysis suggests that pemetrexed based regimens are associated with mild activity with good tolerability in treating patients with metastatic colorectal cancer.

Genomic aberrations of rectal carcinoma, especially DNA copy number changes associated with metastasis were largely unclear. We aim to identify the metastasis associated biomarkers in stage II rectal cancer. Formalin-fixed, paraffin-embedded primary tumor tissues of stage II rectal carcinoma were analyzed by array-based comparative genomic hybridization, and genomic aberrations were identified by Genomic Workbench and SAM software. Copy number changes and mRNA expressions were validated by Real-time PCR in an independent rectal cancer samples. The results showed that the most frequent gains in stage II rectal cancer were at 1q21.2-q23.1, 3p21.31, 11q12.2-q23.3, 12q24.11-q24.31, 12q13.11-q14.1 and losses in 18q11.2-q23, 17q21.33-q22, 13q31.1-q31.3, 21q21.1-q21.3, 8p23.3-p23.1 and 4q22.1-q23. Twenty-two amplifications and five homozygous deletions were also identified. We further found that S100A1 (1q21.3-q23.1), MCM7 (7q22.1) and JUND (19p13.11) were amplified and overexpressed in stage II rectal cancer. Interestingly, the genomic aberrations affected 14 signaling pathways including VEGF signaling pathway and fatty acid metabolism. Most importantly, loss of 13q31.1-q34 and gain of 1q44 were associated with distant metastasis. Our results indicated that these metastasis associated genomic changes may be useful to reveal the pathogenesis of rectal cancer metastasis and identify candidate biomarkers.

Impact of Caspase-8 (CASP8) -652 6N Del and D302H Polymorphisms on Prostate Cancer in Different Ethnic Groups

Zhang, Cheng-Dong,Li, Hong-Tao,Liu, Kun,Lin, Zhi-Di,Peng, Qi-Liu,Qin, Xue,He, Min,Wu, Hua,Mo, Zeng-Nan,Yang, Xiao-Li Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.18

Background: Despite evidence suggesting roles for caspase-8 (CASP8) -652 6N del and D302H polymorphisms in prostate cancer (PCa), the association of these polymorphisms with PCa risk remains inconclusive. Therefore, a meta-analysis was performed to more precisely estimate the association of CASP8 -652 6N del and D302H polymorphisms with PCa susceptibility. Materials and Methods: A comprehensive literature search was conducted to identify all case-control studies of CASP8 D302H and -652 6N del polymorphisms and PCa risk. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of the association and the precision of the estimate, respectively. Results: Nine -625 6N del studies and 4 D302H studies were included. CASP8 -652 6N del and D302H polymorphisms were not significantly associated with PCa risk in the overall analyses. However, in the subgroup analysis stratified by ethnicity, -625 6N del was significantly associated with PCa risk in the East Asian and Indian populations under the recessive model. Furthermore, the subgroup analysis strongly suggested that D302H was associated with lower PCa risk in the Non-Indian population under the dominant model. Conclusions: In our meta-analysis, ethnic-specific differences were evident in the association of CASP8-625 6N del and D302H polymorphisms with PCa risk.

PurposeRadiation-induced dermatitis (RD) is a common side-effect of therapeutic ionizing radiation that can severely affect patient quality of life. This study aimed to develop a risk prediction model for the occurrence of RD in patients with cervical carcinoma undergoing chemoradiotherapy using electronic medical records (EMRs). MethodsUsing EMRs, the clinical data of patients who underwent simultaneous radiotherapy and chemotherapy at a tertiary cancer hospital between 2017 and 2022 were retrospectively collected, and the patients were divided into two groups: a training group and a validation group. A predictive model was constructed to predict the development of RD in patients who underwent concurrent radiotherapy and chemotherapy for cervical cancer. Finally, the model's efficacy was validated using a receiver operating characteristic curve. ResultsThe incidence of radiation dermatitis was 89.5% (560/626) in the entire cohort, 88.6% (388/438) in the training group, and 91.5% (172/188) in the experimental group. The nomogram was established based on the following factors: age, the days between the beginning and conclusion of radiotherapy, the serum albumin after chemoradiotherapy, the use of single or multiple drugs for concurrent chemotherapy, and the total dose of afterloading radiotherapy. Internal and external verification indicated that the model had good discriminatory ability. Overall, the model achieved an area under the receiver operating characteristic curve of .66. ConclusionsThe risk of RD in patients with cervical carcinoma undergoing chemoradiotherapy is high. A risk prediction model can be developed for RD in cervical carcinoma patients undergoing chemoradiotherapy, based on over 5 years of EMR data from a tertiary cancer hospital.
