PICH, A protein that maintains genomic stability, can promote tumor growth.

Genomic instability is regardedas a hallmark of cancer cells. It can be presented in many ways, among which chromosome instability has received attention. Ultrafine anaphase bridges are a typeof chromatin bridges, the untimely resolution of which can also lead to chromosome instability. PICH can play a role in maintaining chromosome stability by regulating chromosome morphologyand resolving ultrafine anaphase bridges. Recently, PICH has been found to be overexpressed in various cancers. Overexpression of PICH is related to the proliferation of tumors and poor prognosis. In this article, we consider that PICH can maintain genome stability by regulating appropriate chromosome structure, ensuring proper chromosome segregation, and facilitating replication fork reversal. We summarize how PICH regulates chromosome stability, how PICH resolves Ultrafine anaphase bridges with other proteins, and how PICH promotes tumor progression.

PICH Activates Cyclin A1 Transcription to Drive S-Phase Progression and Chemoresistance in Gastric Cancer.

The chemotherapeutic agent 5-fluorouracil (5-FU) remains the backbone of postoperative adjuvant treatment for gastric cancer. However, fewer than half of patients with gastric cancer benefit from 5-FU-based chemotherapies owing to chemoresistance and limited clinical biomarkers. Here, we identified the SNF2 protein Polo-like kinase 1-interacting checkpoint helicase (PICH) as a predictor of 5-FU chemosensitivity and characterized a transcriptional function of PICH distinct from its role in chromosome separation. PICH formed a transcriptional complex with RNA polymerase II (Pol II) and ATF4 at the CCNA1 promoter in an ATPase-dependent manner. Binding of the PICH complex promoted cyclin A1 transcription and accelerated S-phase progression. Overexpressed PICH impaired 5-FU chemosensitivity in human organoids and patient-derived xenografts. Furthermore, elevated PICH expression was negatively correlated with survival in postoperative patients receiving 5-FU chemotherapy. Together, these findings reveal an ATPase-dependent transcriptional function of PICH that promotes cyclin A1 transcription to drive 5-FU chemoresistance, providing a potential predictive biomarker of 5-FU chemosensitivity for postoperative patients with gastric cancer and prompting further investigation into the transcriptional activity of PICH. SIGNIFICANCE: PICH binds Pol II and ATF4 in an ATPase-dependent manner to form a transcriptional complex that promotes cyclin A1 expression, accelerates S-phase progression, and impairs 5-FU chemosensitivity in gastric cancer.

Exploring the role of FBXO5 in gastric cancer.

Gastric cancer is one of the most common lethal malignancies in the world, especially in China. Due to the ineffective screening of early gastric cancer and drug resistance of the advanced, the prognosis of gastric cancer remains dismal. Based on bioinformatics and tissue microarray analyses, FBXO5 was selected for analysis in this study. Here, we report the function of FBXO5 in gastric cancer, showing for the first time that it contributes to tumor cell proliferation, clone formation, invasion and migration. In these preliminary findings, FBXO5 promoted the transition of the cell cycle from the G0/G1 to the G2/M phase, which likely resulted from FBXO5 interacting with CDK1 and NCAPG proteins. The relevant mechanism needs to be explored. In addition, FBXO5 participated in the tumor microenvironment and was negatively related to immune activation. FBXO5, an oncogene, plays a role in tumor initiation and progression, and is expected to be a potential target for gastric cancer treatment.

The role of long non-coding RNA FGD5-AS1 in cancer.

Long noncoding RNAs (lncRNAs) refers to a class of RNAs that have at least 200 nucleotides and do not encode proteins, and the relationship between lncRNA and cancer has recently attracted considerable research attention. The lncRNA FGD5-AS1 is a newly discovered lncRNA with a length of 3772 nucleotides. Studies have found that FGD5-AS1 is abnormally highly expressed in many cancer tissues and was closely related to the lymph node metastasis, tumor invasion, survival time, and recurrence rate of various cancers. Mechanistic analyses show that FGD5-AS1 can stabilize mRNA expression by sponging miRNA, which not only induces cancer cell proliferation, metastasis, invasion, and chemoresistance in vitro, but also promotes tumor growth and metastasis in vivo. In addition, FGD5-AS1 can serve as a diagnostic or prognostic marker for a variety of cancers. This review demonstrates the clinical significance of FGD5-AS1 in human cancer and its role in tumorigenesis and tumor progression.

hsa-miR-7-5p suppresses proliferation, migration and promotes apoptosis in hepatocellular carcinoma cell lines by inhibiting SPC24 expression.

Emerging evidence suggests that microRNAs (miRNAs) participate in hepatocellular carcinoma (HCC) progression. Nevertheless, the mechanism of miR-7-5p in HCC cells has not been researched. In the research, the underlying biological function of miR-7-5p and SPC24 in HCC was explored. qRT-PCR was performed to measure the miR-7-5p and SPC24 level in HCC tissues and cells. The effect of miR-7-5p on HCC progression was detected by performing CCK-8, BrdU, and transwell assay. The relationship between miR-7-5p and SPC24 was determined using luciferase and RNA pull-down assays. Our findings showed that miR-7-5p was downregulated in HCC whereas SPC24 was upregulated in HCC. It was also showed that miR-7-5p upregulation restricted malignant behaviors of HCC cells, but this inhibitory effect of miR-7-5p could be relieved by its target gene SPC24. In conclusion, this research suggested that by inhibiting SPC24, miR-7-5p could act as a tumor inhibitory factor in HCC.

To study the intervention mechanism of pediatric massage on intestinal flora and host metabolism in children with anorexia.

BACKGROUND: As a common and frequent disease in pediatric patients, pediatric anorexia (PN) poses a serious threat to childhood growth and health. In recent years, societal changes in lifestyle and diet have increased the incidence of this PN, which has attracted extensive attention from both the medical community and parents. It has been shown that massage therapy represents an effective intervention for the treatment of anorexia, but investigation on its mechanism(s) of action remains limited. In this study, we will explore the biological mechanism(s) of PN from the perspective of intestinal flora, to further reveal its site of action and therapeutic mechanism(s). METHODS: A total of 60 healthy children will be randomly selected for physical examination. According to a random number generated by a computer, children with anorexia who meet the inclusion criteria will be selected. In strict accordance with the time sequence of inclusion, subjects will be randomly assigned to either the massage or control group (n = 60 per group). The blank group will receive no treatment. Children in the massage group will receive a designated massage protocol. The control group will be administered oral Jianweixiaoshi tablets over 4 weeks. Each group will be compared for intestinal flora structure, fecal short chain fatty acids levels, serum trace elements, urine D-xylose-excretion rates, gastric fluid emptying, gastric motility, and hemoglobin levels before and after treatment. RESULTS: We will review the clinical trial registry in China (http://www.chictr.org.cn/searchprojen.aspx), peer-reviewed journals and academic conferences. CONCLUSION: This study will verify the intervention mechanism(s) of pediatric massage on intestinal flora and host metabolism in children with anorexia. TRIAL REGISTRATION NUMBER: ChiCTR2000033274.

Pancreatic fistula after pancreatoduodenectomy due to compression of the superior mesenteric vessels: a case report.

BACKGROUND: Pancreatic fistula is a common complication after pancreaticoduodenectomy, which could be caused by: soft pancreatic tissue, pancreatic duct diameter < 3 mm and body mass index ≥25 kg/m2. Here we report a case of pancreatic fistula due to obstruction of the jejunal loop due to compression of the jejunal loop by the superior mesenteric vessels. CASE PRESENTATION: A 68-year-old man was admitted to our ward due to intermittent epigastric distension and pain. After various examinations and treatments, he was diagnosed with middle bile duct cancer. Pancreaticoduodenectomy was performed, and pancreaticojejunostomy and hepaticojejunostomy were completed by lifting the jejunal loop from behind the superior mesenteric vessels to the upper region of the colon. On postoperative day 9, the patient developed acute diffuse peritonitis, and on postoperative day 10, the patient underwent a second exploratory laparotomy, during which it was confirmed that the pancreatic fistula was caused by obstruction of the jejunal loop due to compression of the jejunal loop by the superior mesenteric vessels, then the patient recovered and was discharged alive after retrograde drainage in the jejunum. CONCLUSIONS: The superior mesenteric vessels after pancreaticoduodenal surgery can compress the jejunal loop and cause obstruction leading to serious complications, and it is recommended that general surgeons should avoid lifting the jejunal loop from the posterior aspect of the superior mesenteric vessels to complete the anastomosis.

Prognostic value of carbohydrate antigen125 and carcino embryonic antigen expression in patients with colorectal carcinoma and its guiding significance for chemotherapy.

The aim of this study is to evaluate the predictive value of carbohydrate antigen125 (CA125) and carcino embryonic antigen (CEA) expression and its guiding role of choosing chemotherapy regimen in post-operation patients with colorectal carcinoma.The clinical data of all patients, including laboratory data and pathological data, were collected from the electronic medical records. Kaplan-Meier Log rank test, COX regression model and subgroup analyses were employed to assess the correlation between the expression of CA125 and CEA in patients with colorectal carcinoma and the survival, and the effect on chemotherapy efficacy.Kaplan-Meier showed that CA125 expression is negatively related to the progression-free survival (PFS) of the post-operative patients, Median PFS was 1140 days in the patients with high expression, and Median PFS was 1387 days in the patients with low expression (χ = 4.715, P = .030); CEA expression is also negatively associated with the PFS of the post-operative patients, Median PFS was 1197 days in the patients with high expression, and Median PFS was 1424 days in the patients with low expression (χ = 4.992, P = .025). Subgroup analysis also showed that the patients with normal CA125 and CEA had better prognosis, median PFS was 1505 days, and the patients with CA125 and (or) CEA high expression had poor prognosis and median PFS was 1162 days (χ = 13.346, P = .001), and found that there was no statistical difference in patients with oxaliplatin plus capecitabine (XELOX) and oxaliplatin, 5-fluorouracil and Calcium folinate (FOLFOX) chemotherapy in patients with CA125 and CEA low expression. However, in these patients with CA125 or (and) CEA high expression, the median PFS of patients treated with XELOX was 1082 days, and the median PFS of patients treated with FOLFOX chemotherapy was 1335 (χ = 4.547, P = .033).Expression of CA125 and CEA associated with the survival of patients, and have some guiding significance for chemotherapy in patients with colorectal cancer after operation; Compared with XELOX, FOLFOX chemotherapy is more effective for CA125 or (and) CEA high expression patients with colorectal carcinoma.

Integrative analysis of dysregulated lncRNA-associated ceRNA network reveals potential lncRNA biomarkers for human hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is an aggressive cancer with a poor prognosis and a high incidence. The molecular changes and novel biomarkers of HCC need to be identified to improve the diagnosis and prognosis of this disease. We investigated the current research concentrations of HCC and identified the transcriptomics-related biomarkers of HCC from The Cancer Genome Atlas (TGCA) database. METHODS: We investigated the current research concentrations of HCC using literature metrology analysis for studies conducted from 2008 to 2018. We identified long noncoding RNAs (lncRNAs) that correlated with the clinical features and survival prognoses of HCC from The Cancer Genome Atlas (TGCA) database. Differentially expressed genes (lncRNAs, miRNAs, and mRNAs) were also identified by TCGA datasets in HCC tumor tissues. A lncRNA competitive endogenous RNA (ceRNA) network was constructed from lncRNAs based on intersected lncRNAs. Survival times and the association between the expression levels of the key lncRNAs of the ceRNA network and the clinicopathological characteristics of HCC patients were analyzed using TCGA. Real-time polymerase chain reaction (qRT-PCR) was used to validate the reliability of the results in tissue samples from 20 newly-diagnosed HCC patients. RESULTS: Analysis of the literature pertaining to HCC research revealed that current research is focused on lncRNA functions in tumorigenesis and tumor development. A total of 128 HCC dysregulated lncRNAs were identified; 66 were included in the co-expressed ceRNA network. We analyzed survival times and the associations between the expression of 66 key lncRNAs and the clinicopathological features of the HCC patients identified from TCGA. Twenty-six lncRNAs were associated with clinical features of HCC (P < 0.05) and six key lncRNAs were associated with survival time (log-rank test P < 0.05). Six key lncRNAs were selected for the validation of their expression levels in 20 patients with newly diagnosed HCC using qRT-PCR. Consistent fold changes in the trends of up and down regulation between qRT-PCR validation and TCGA proved the reliability of our bioinformatics analysis. CONCLUSIONS: We used integrative bioinformatics analysis of the TCGA datasets to improve our understanding of the regulatory mechanisms involved with the functional features of lncRNAs in HCC. The results revealed that lncRNAs are potential diagnostic and prognostic biomarkers of HCC.

Primary synovial sarcoma of the duodenal bulb: a case report and review of the literature.

Primary synovial sarcoma of the duodenal bulb is a rare mesenchymal tumor with special morphological features. It usually originates from the major joints or tendon sheaths of the extremities and mostly seen in young population, but rarely found in gastrointestinal tract. In this manuscript, we reported the first case of synovial sarcoma arising between the intestinal wall of the duodenal bulb with a concomitant SYT/SSX type of the t(X;18) translocation. A 49-year-old male presented to our hospital with a 2-month history of upper abdominal pain along with a 4-day amply jaundice. Tumor marker testing showed only a slight increase of carbohydrate antigen 19-9 (CA19-9). A computed tomography scan of his abdomen showed that indeterminate tissue occupied the duodenal bulb wall, compressed the surrounding tissues, and measured roughly 5.0 cm × 7.7 cm × 8.7 cm. Since the sarcoma grows between the intestinal wall, which cannot be detected by endoscopy, an initial diagnosis of duodenal wall stromal tumor was made at that time. Postoperative Immunohistochemistry results showed that the tumor was positive for the expression of transducin-like enhancer of split 1, B-cell lymphoma 2, and Vimentin. These pathological findings were indicative of the diagnosis of synovial sarcoma, but still did not provide sufficient diagnostic evidence. Finally we confirmed the diagnosis by using fluorescence in situ hybridization (FISH) with detection of the t(X;18) (SYT-SSX) translocation. No such lesions were found on preoperative examination, so a diagnosis of primary duodenal synovial sarcoma was made. After literature review, we found four reports of duodenal synovial sarcomas, all of which could be detected endoscopically, but there were no results of long-term follow-up. This case is the first reported case of synovial sarcoma arising between the intestinal walls of the duodenal bulb treated twice with ifosfamide and followed up for 13 months without recurrence.

Docetaxel, oxaliplatin, leucovorin, and 5-fluorouracil (FLOT) as preoperative and postoperative chemotherapy compared with surgery followed by chemotherapy for patients with locally advanced gastric cancer: a propensity score-based analysis.

Introduction: Docetaxel, oxaliplatin, leucovorin, and 5-fluorouracil (FLOT) may improve overall survival (OS) in patients with locally advanced gastric cancer (LAGC); however, evidence for its use as a standard treatment has not been established in China. The aim of this study was to investigate the effectiveness, safety, and feasibility of the FLOT regimen as neoadjuvant chemotherapy in Chinese patients with resectable LAGC. Methods: We conducted an observational study to compare the effectiveness of FLOT regimen consisting of docetaxel (60 mg/m2), oxaliplatin (85 mg/m2), leucovorin (200 mg/m2), and 5-fluorouracil (2,600 mg/m2 as a 24 hr infusion), all given on day 1 and administered every 2 weeks versus initial surgery followed by chemotherapy in patients with clinical T3-4 LAGC. OS was compared by using the Cox proportional hazards regression model and the Kaplan-Meier curve adjusted by inverse probability of treatment weighting (IPTW) and propensity score-matched (PSM) analysis. In addition, we performed subgroup analyses to determine the effectiveness of the FLOT regimen in clinically relevant patient subsets. Results: Overall, 47 patients who received initial FLOT chemotherapy and 269 patients who received initial surgery were enrolled in this study. In the PSM analysis, the FLOT-first group showed favorable OS compared with the surgery-first group (41 vs 41 [HR, 0.416; 95% CI, 0.218-0.794; P=0.008]), and 3-year survival rates were 58.7% and 30.9% in the FLOT-first group and surgery-first group, respectively. IPTW analysis showed similar results. However, the effect of FLOT was low (HR, 0.868; 95 CI%, 0.215-3.504) in patients without lymph node metastasis. Conclusion: Our study suggests that preoperative FLOT chemotherapy is safe and feasible. In terms of OS, FLOT may be superior to initial surgery followed by chemotherapy in reducing morbidity with resectable LAGC.

Genetic variants in cell death pathway genes and HBV-related hepatocellular carcinoma among a Chinese Han population.

Cell death pathway plays an important role in apoptosis, and corruption of this signaling pathway has been shown to participate in carcinogenesis. We aimed at determining whether genetic variants in CASP8, CASP10 and CFLAR influence the development and clinical outcomes of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). A hospital-based case-control study, including 600 HCC cases and 600 HBsAg positive controls without HCC, was conducted to assess the relationship between 11 tagging SNPs in CASP8, CASP10 and CFLAR and HBV-related HCC risk and prognosis in a Chinese Han population. Among the 11 polymorphisms, only CASP8 rs3834129 (-652 6N ins/del) modified HCC risk. Compared with CASP8 -652 insins genotype, the deldel (adjusted OR 0.717, 95% CI 0.553-0.930) and insdel (adjusted OR 0.731, 95% CI 0.554-0.964) genotypes had a significantly decreased HCC risk. Furthermore, this polymorphism was significantly associated with decreased portal vein tumor thrombosis (adjusted OR 0.554; P = 0.044) and reduced postoperative recurrence (adjusted OR 0.356; P < 0.001) of resected HCC. In addition, the multivariate analysis showed that the -652 6N ins/del polymorphism was significantly associated with improved overall survival and recurrence-free survival of resected HCC patients. The expression levels of CASP8 in HCC tumor tissues were significantly lower than those in paracancerous liver tissues, although no significant association between -652 6N ins/del genotypes and the expression levels of CASP8 were observed in these tissues. These results suggest that the CASP8 -652 6N ins/del polymorphism may play a protective role in the development, progression, and survival of HBV-related HCC among the Chinese Han population.

CASP 3 genetic polymorphisms and risk of Hepatocellular carcinoma: a case-control study in a Chinese population.

Caspase (CASP) 3 is an important caspase in the apoptosis pathway and plays an important role in the development and progression of cancer. We hypothesized that genetic variants in CASP 3 may modify individual susceptibility to hepatocellular carcinoma (HCC). Five hundred HCC cases in West China Hospital were selected, and 500 healthy cases with the same gender, age (±5 years), and residence place were selected as control group, with proportion of 1:1. The matrix-assisted laser desorption ionization time-of-flight mass spectrometry method was performed to detect these polymorphisms. Among the 500 cases and 500 controls with DNA samples, the genotyping was successful for the CASP3 polymorphisms (rs6948, rs1049216, and rs12108497) in 486 HCC cases and 495 controls, which were included in the final analyses.The results showed that the genotype frequencies of the CASP3 did not differ significantly between the HCC patients and the control group (P > 0.05). However, when stratifying by age, sex, smoking, drinking, HBV carrier status, and family history of cancer, we found that the variant genotypes (CT + TT) of the CASP3 rs12108497 were associated with a significant increased risk of HCC among smoking individuals (adjusted OR = 2.31, 95 % CI = 1.11-4.79). No significant association was observed between the other two polymorphisms of the CASP3 gene and risk of HCC in any stratification analysis. These results suggest that the CASP3 rs12108497 polymorphism may play a role in the development of HCC among smoking individuals in the Chinese population.

[The Evaluation Value of Methylation Status of CpG Island of SFRP1 and LINE1 Gene Promoter Area in the Prognosis of Hepatocellular Carcinoma.]

OBJECTIVES: To investigate the relationship between aberrant promoter CpG islands methylation status of secreted frizzled related protein 1 (SFRP1) and long intersper sed nuclear element 1 (LINE1) gene and clinicopathologic parameters to determine their prognosis value for hepatocellular carcinoma (HCC). METHODS: 105 cases of HCC and 50 cases of normal people plasma were collected,and then the promoter hypermethylation status of SFRP1 and hypormethylation status of LINE1 were examined by methylation specific PCR (MSP); The relationship between SFRP1/LINE1 methylation status and patients' clinicopathologic factors was analyzed;The association between SFRP1/LINE1 methylation status and disease-free survival and overall survival was analyzed by Kaplan-Meier curves,the log-rank test,and multivariate Cox regression. RESULTS: SFRP1 gene promoter CpG islands hypermethylation and LINE1 gene promoter CpG islands hypomethylation were found in 59.05% (62/105) and 66.67% (70/105) of 105 cancerous plasma cases,repectively,SFRP1 hypermethylation status and LINE1 hypomethylation status in plasma of HCC account for 43.81%(62/105) and no positive methylation cases were detected in normal cases;The hypermethylation status of SFRP1 and hypomethylation status of LINE1 gene were related with HBsAg and α-fetoprotein (AFP) level;There was statistically significant difference between CpG islands hypermethylation of two genes and disease-free survival rate and overall survival rate;The group patients with SFRP1 hypermethylation positive and LINE1 hypomethylation positive demonstrated the worst prognosis while the group with SFRP1 hypermethylation negative and LINE1 hypomethylation negative had the best prognosis. CONCLUSIONS: The promoter methylation of SFRP1 and LINE1 is correlated with the occurrence and development of HCC.SFRP1 and LINE1 might be potential and reliable biomarkers for predicting prognosis in HCC patients.

Enhanced recovery after surgery programs in patients undergoing hepatectomy: A meta-analysis.

AIM: To evaluate the impact of enhanced recovery after surgery (ERAS) programs in comparison with traditional care on liver surgery outcomes. METHODS: The PubMed, EMBASE, CNKI and Cochrane Central Register of Controlled Trials databases were searched for randomized controlled trials (RCTs) comparing the ERAS program with traditional care in patients undergoing liver surgery. Studies selected for the meta-analysis met all of the following inclusion criteria: (1) evaluation of ERAS in comparison to traditional care in adult patients undergoing elective open or laparoscopic liver surgery; (2) outcome measures including complications, recovery of bowel function, and hospital length of stay; and (3) RCTs. The following exclusion criteria were applied: (1) the study was not an RCT; (2) the study did not compare ERAS with traditional care; (3) the study reported on emergency, non-elective or transplantation surgery; and (4) the study consisted of unpublished studies with only the abstract presented at a national or international meeting. The primary outcomes were complications. Secondary outcomes were length of hospital stay and time to first flatus. RESULTS: Five RCTs containing 723 patients were included in the meta-analysis. In 10/723 cases, patients presented with benign diseases, while the remaining 713 cases had liver cancer. Of the five studies, three were published in English and two were published in Chinese. Three hundred and fifty-four patients were in the ERAS group, while 369 patients were in the traditional care group. Compared with traditional care, ERAS programs were associated with significantly decreased overall complications (RR = 0.66; 95%CI: 0.49-0.88; P = 0.005), grade I complications (RR = 0.51; 95%CI: 0.33-0.79; P = 0.003), and hospital length of stay [WMD = -2.77 d, 95%CI: -3.87-(-1.66); P < 0.00001]. Similarly, ERAS programs were associated with decreased time to first flatus [WMD = -19.69 h, 95%CI: -34.63-(-4.74); P < 0.0001]. There was no statistically significant difference in grade II-V complications between the two groups. CONCLUSION: ERAS is a safe and effective program in liver surgery. Future studies should define the active elements to optimize postoperative outcomes for liver surgery.

Ultrasonic integrated backscatter in assessing liver steatosis before and after liver transplantation.

BACKGROUND: Liver steatosis affects 20%-30% of adults. Because of the increasing gap between graft supplies and demands, livers with steatosis are frequently used in liver transplantation. But severely steatotic liver grafts are associated with a high risk of intraoperative and postoperative complications. Accurate assessment of fat content of donor livers and monitoring of the extent of steatosis in recipients are required for liver transplantation. The present study aimed to determine the correlation between liver echogenicity and fat content, and to evaluate the use of an ultrasonic integrated backscatter system (IBS) in the assessment of changes in fat content after liver transplantation. METHODS: Seventy-nine consecutive patients receiving liver grafts from living donors were evaluated in our center. Of these recipients, 67 survived for more than two years and were included in this study. Each liver graft was evaluated with IBS and ultrasound before operation and the fat content was estimated. The fat content of the grafts in the recipients was again assessed with ultrasound at 18 months after surgery. RESULTS: A correlation was detected between each graft's IBS value and its fat content (P=0.001). The IBS value in fatty grafts with various degrees of steatosis was significantly decreased in 3 (P=0.02), 12, 15 and 18 (P=0.001) months after orthotopic liver transplantation. The IBS value returned to normal in all patients in 18 months after liver transplantation. CONCLUSIONS: Decreased fat content in steatotic grafts can be observed in all recipients. Ultrasonic IBS is useful in determining the steatotic degree of grafts in donors as well as in monitoring the grafts after liver transplantation.

Treatment of spontaneous ruptured hepatocellular carcinoma: A single-center study.

OBJECTIVES: Spontaneous rupture of hepatocarcinoma (HCC) is a fatal complication of advanced HCC and is associated with poor prognosis. However, there is no consensus on the best approach to treat hemoperitoneum due to ruptured HCC. In this paper, we evaluate and discuss the outcomes of different treatment methods employed at our center for ruptured HCC. METHODS: We reviewed the medical records of 132 patients diagnosed with ruptured HCC at our hospital from January 2003 to December 2012 and evaluated and compared the outcomes of five treatment methods for ruptured HCC: conservative treatment, surgical hemostasis, transarterial embolization (TAE), and one- and two-stage resections. RESULTS: There was no significant difference in the median survival time between the conservative treatment and surgical hemostasis groups. Patients in the TAE alone group had a better prognosis than those in the conservative treatment and surgical hemostasis groups. The survival time of the tumor resection group was obviously better than that of the conservative treatment, surgical hemostasis, and TAE alone groups, but no significant difference was observed between the one-stage and two-stage resection groups. CONCLUSIONS: One-stage hepatectomy is a better option for patients with preserved liver function, whereas TAE is a better option for those with poorly preserved liver function.

Radiochemotherapy versus radiotherapy in locally advanced cervical cancer: a meta-analysis.

OBJECTIVE: The objectives of this review are to compare the effectiveness and safety of radiochemotherapy (RTCT) with radiotherapy (RT) alone in locally advanced cervical cancer (LACC). DATA SOURCES: We comprehensively searched the Cochrane library, Medline, EMBASE, Chinese biomedicine literature database, Chinese scientific full-text database and Chinese journal full-text database for relevant articles. The computer search was supplemented with a manual search of reference lists for all available review articles. Also reference lists of the included studies were reviewed. RESULTS: We included 18 randomized trials involving 3,517 patients. Meta-analysis results are as follows: the response rate, 3 and 5-year survival rates were significantly better in patients in the RTCT group than in RT group. As adverse effects, limited evidence suggests that there was no significant difference between the two groups with regard to rectitis, cystitis, nausea and vomiting. But RTCT group has higher incidence rates than RT group in gastrointestinal, myelosuppression and leucopenia. CONCLUSION: The combination of radiotherapy and chemotherapy was more effective for LACC than radiotherapy alone. There was no significant difference between the RTCT regimen group and RT regimen group with regard to adverse effects.

Epidermal growth factor +61 G/A polymorphism and the risk of hepatocellular carcinoma in a Chinese population.

BACKGROUND: Chronic hepatitis B virus (HBV) infection is a risk factor of hepatocellular carcinoma (HCC) in China. Epidermal growth factor (EGF) plays an important role in tumorigenesis. The association between EGF +61 G/A polymorphism and the risk of HCC is still controversial and ambiguous. AIM: The objective of this study was to investigate the association between EGF +61 G/A polymorphism and the risk of HCC in a Chinese population. METHODS: A hospital-based case-control study was designed in a Chinese population. EGF +61 G/A polymorphisms were determined in 120 chronic HBV-infected HCC patients, 120 chronic HBV-infected cirrhotic patients, and 120 healthy controls. The genotype frequency of this polymorphism was determined by using a polymerase chain reaction-restriction fragment length polymorphism assay. RESULTS: EGF +61 GG (odds ratio=2.76, 95% confidence interval=1.03, 7.38; p=0.04) and G allele frequencies (odds ratio=1.59, 95% confidence interval=1.08, 2.34; p=0.02) in the HCC group were higher than those in the cirrhosis group. EGF +61 A and G allele frequencies in healthy subjects were 28.8% and 71.2%. No relationship between EGF +61 G/A gene polymorphism and HCC risk was found among our recruited HCC patients and healthy controls. CONCLUSION: This study suggests that EGF +61 GG genotype is associated with a higher risk of chronic HBV-infected HCC in the Chinese population.
