[Research progress in raw and processed Raphani Semen and prediction of quality markers].

Raphani Semen, with both edible and medicinal values, is a typical Chinese herbal medicine with different effects before and after processing. The raw helps ascending and the cooked helps descending. This paper comprehensively summarizes the differences in chemical constituents and pharmacological effects between raw and processed Raphani Semen that are reported in recent years. Based on the principle of quality markers(Q-markers) of traditional Chinese medicines, the chemical constituent sources, chemical constituent detection techniques, and correlation between bidirectional regulatory efficacy and chemical constituents are compared between raw and processed Raphani Semen. The results suggest that sulforaphene and glucoraphanin could be used as candidate Q-markers of raw and processed Raphani Semen, respectively. This review is expected to provide a reference for further research on the processing, new drug development, and improvement of safety and effectiveness of Raphani Semen in clinical application.

Hyperthermia enhances radiosensitivity of colorectal cancer cells through ROS inducing autophagic cell death.

Hyperthermia (HT) enhances the anti-cancer effects of radiotherapy (RT), but the precise biochemical mechanisms involved are unclear. This study was aim to investigate if mild HT sensitizes colorectal cancer cells to RT through reactive oxygen species (ROS)-inducing autophagic cell death in a mice model of HCT116 human colorectal cancer. HCT116 mice model were randomly divided into five groups: mock group, hyperthermia group (HT), radiotherapy group (RT), HT + RT group, and HT + RT +N-acetyl L-cysteine (NAC) group (HT + CT + NAC). After four weeks of treatment, cancer growth inhibition, rate and mitochondrial membrane potential were measured with MTT and JC-1 assays, respectively, while ROS were estimated fluorimetrically. The relationship of these parameters to expressions of autophagy-related genes Beclin1, LC3B, and mTOR was analyzed. Gene expression was measured by Real-Time polymerase chain reaction (RT-PCR). There were significant increases in ROS levels and mitochondrial membrane potential in the HT + RT group. ROS levels in the HT + RT group increased more significantly than in any other group. In contrast, ROS levels in the HT + RT + NAC group were significantly decreased relative to the HT + RT group. The number of autophagic bodies in HT + RT group was higher than that of mock group. There were significant increases in the expression of Beclin1 and LC3B genes, while mTOR expression was significantly decreased in the HT + CT group. Treatment with NAC reversed the pattern of these changes. These results indicate that HT enhances the radiosensitivity of colorectal cancer cells to RT through ROS inducing autophagic cell death.

Mild hyperthermia enhances sensitivity of gastric cancer cells to chemotherapy through reactive oxygen species-induced autophagic death.

Mild hyperthermia enhances anti-cancer effects of chemotherapy, but the precise biochemical mechanisms involved are not clear. This study was carried out to investigate whether mild hyperthermia sensitizes gastric cancer cells to chemotherapy through reactive oxygen species-induced autophagic death. In total, 20 BABL/c mice of MKN-45 human gastric cancer tumor model were divided into hyperthermia + chemotherapy group, hyperthermia group, chemotherapy group, N-acetyl-L-cysteine group, and mock group. Reactive oxygen species production and expression of autophagy-related genes Beclin1, LC3B, and mammalian target of rapamycin were determined. The relationships between tumor growth regression, expression of autophagy-related genes, and reactive oxygen species production were evaluated. Tumor size and wet weight of hyperthermia + chemotherapy group was significantly decreased relative to values from hyperthermia group, chemotherapy group, N-acetyl-L-cysteine group, and mock group ( F = 6.92, p < 0.01 and F = 5.36, p < 0.01, respectively). Reactive oxygen species production was significantly higher in hyperthermia + chemotherapy group than in hyperthermia, chemotherapy, and mock groups. The expression levels of Beclin1 and LC3B were significantly higher, while those of mammalian target of rapamycin were significantly lower in hyperthermia + chemotherapy group than in hyperthermia, chemotherapy, and mock groups. Tumor growth regression was consistent with changes in reactive oxygen species production and expression of autophagy-related genes. N-acetyl-L-cysteine inhibited changes in the expression of the autophagy-related genes and also suppressed reactive oxygen species production and tumor growth. Hyperthermia + chemotherapy increase expression of autophagy-related genes Beclin1 and LC3B, decrease expression of mammalian target of rapamycin, and concomitantly increase reactive oxygen species generation. These results strongly indicate that mild hyperthermia enhances sensitivity of gastric cancer cells to chemotherapy through reactive oxygen species-induced autophagic death.

Thermo-chemotherapy Induced miR-218 upregulation inhibits the invasion of gastric cancer via targeting Gli2 and E-cadherin.

Thermo-chemotherapy has been proven to reduce the invasion capability of cancer cells. However, the molecular mechanism underlying this anti-invasion effect is still unclear. In this study, the role of thermo-chemotherapy in the inhibition of tumor invasion was studied. The results demonstrated that expression of miR-218 was downregulated in gastric cancer tissues, which had a positive correlation with tumor invasion and metastasis. In vitro thermo-chemotherapy increased miR-218 expression in SGC7901 cells and inhibited both proliferation and invasion of cancer cells. Gli2 was identified as a downstream target of miR-218, and its expression was negatively regulated by miR-218. The thermo-chemotherapy induced miR-218 upregulation was also accompanied by increasing of E-cadherin expression. In conclusion, the present study indicates that thermo-chemotherapy can effectively decrease the invasion capability of cancer cells and increase cell-cell adhesion. miR-218 and its downstream target Gli2, as well as E-cadherin, participate in the anti-invasion process.

Multivariate comparison of B-ultrasound guided and laparoscopic continuous circulatory hyperthermic intraperitoneal perfusion chemotherapy for malignant ascites.

OBJECTIVE: Clinical efficacy of B-ultrasound-guided and laparoscopy-assisted continuous hyperthermic intraperitoneal perfusion chemotherapy (CHIPC) for treatment of malignant ascites was investigated. METHODS: Sixty-two patients with malignant ascites induced by ovarian or gastrointestinal cancers were randomly treated with B-ultrasound-guided CHIPC (therapeutic group) or laparoscopy-assisted CHIPC (control group) performed at the same center. Hospitalization costs and surgical duration were evaluated. Follow-up was conducted for 21 months with B-ultrasound or computed tomography at least once per month for assessment of ascites amount and tumor progression. Clinical efficacy was assessed by modified World Health Organization criteria. Survival time, Karnofsky performance score (KPS) of quality of life (QOL), and complications were recorded for all patients. RESULTS: Overall condition, primary disease type, and ascites amounts were comparable between groups. Significantly shorter mean duration of perfusion catheter placement (35 vs. 85 min) and mean hospitalization cost (36,000 vs. 55,000 ¥/patient) were observed in the therapeutic group than the control group (P < 0.01). Significantly different KPS scores were not observed before or after CHIPC (23.13 vs. 22.64 %) in both groups (P > 0.05). No significant differences in objective remission rates of malignant ascites (93.75 vs. 93.34 %), median survival times (9 vs. 8 months), or stamp hole metastasis rates (18.75 vs. 18.15 %) were observed between groups (P > 0.05). CONCLUSIONS: B-ultrasound-guided and laparoscopy-assisted CHIPC have similar clinical efficacy for improving QOL and prolonging patient survival. B-ultrasound-guided CHIPC may, however, shorten operation times and reduce hospitalization costs, making the treatment available to a broader patient population, although port hole metastasis remains an issue.

Treatment of gestational choriocarcinoma and massive ascites by hypothermic intraperitoneal perfusion chemotherapy guided by ultrasound followed by cytoreductive surgery.

A 33-year-old woman with very poor health status was admitted to our hospital because she had experienced increasing abdominal distention for three months, CT examination showed a right ovarian tumor together with massive abdominal and pelvic fluid. The patient was first treated by continuous circulatory hypothermic intraperitoneal perfusion chemotherapy (HIPC) guided by B-mode ultrasound, followed by cytoreductive surgery (CRS) after her ascites was controlled and her health condition improved. She was diagnosed with gestational choriocarcinoma (GC) based on the pathological examination of the hysterectomy specimen. She is still alive with very good health today. We think it may be a good choice for a patient in very poor health with GC accompanied by massive ascites to perform HIPC guided by B-mode ultrasound firstly, followed by CRS when the ascites has relieved and the patient's health has improved.

Knockdown of lncRNA ZNRD1-AS1 suppresses gastric cancer cell proliferation and metastasis by targeting the miR-9-5p/HSP90AA1 axis.

LncRNAs play an important role in a variety of biological processes, such as cancer pathogenesis. The lncRNA zinc ribbon domain containing 1 antisense RNA 1 (ZNRD1-AS1) is a natural antisense transcript of ZNRD1. In this study, we found that ZNRD1-AS1 levels were significantly upregulated in gastric cancer tissues compared to those in adjacent healthy gastric tissues. ZNRD1-AS1 levels were correlated with lymph node metastasis, distal metastasis, and TNM stage, but were not correlated with age and sex. ZNRD1-AS1 knockdown suppressed cell proliferation, migration, and invasion, and promoted apoptosis. ZNRD1-AS1 overexpression had the opposite effect. ZNRD1-AS1 knockdown suppressed tumor growth and pulmonary metastasis in a nude mouse model ZNRD1-AS1 can bind to miR-9-5p and ZNRD1-AS1 knockdown can decrease the protein level of heat shock protein 90 alpha family class A member 1 (HSP90AA1), which is the target of miR-9-5p. The miR-9-5p inhibitor rescued the effect of ZNRD1-AS1 knockdown, and the mutant of miR-9-5p binding site on ZNRD1-AS1 sequence blocked the effect of ZNRD1-AS1 overexpression. In conclusion, ZNRD1-AS1 levels were upregulated in gastric cancer tissues, and knockdown of ZNRD1-AS1 suppressed gastric cancer cell proliferation and metastasis by targeting the miR-9-5p/HSP90AA1 axis. Our findings provide novel insights into the mechanism underlying the role of ZNRD1-AS1 in gastric cancer.

LncRNA AC093818.1 accelerates gastric cancer metastasis by epigenetically promoting PDK1 expression.

Gastric cancer (GC) is a highly prevalent type of metastatic tumor. The mechanisms underlying GC metastasis are poorly understood. Some long noncoding RNAs (lncRNAs) reportedly play key roles in regulating metastasis of GC. However, the biological roles of five natural antisense lncRNAs (AC093818.1, CTD-2541M15.1, BC047644, RP11-597M12.1, and RP11-40A13.1) in GC metastasis remain unclear. In this study, the expression of these lncRNAs was measured by quantitative reverse transcription-polymerase chain reaction. Migration and invasion were evaluated by wound-healing and the Transwell assay, respectively. Stable cells were injected into the tail veins of nude mice. Sections of collected lung and liver tissues were stained using hematoxylin and eosin. Protein expression was analyzed by western blot. RNA immunoprecipitation (RIP) assay was used to verify whether the STAT3 and SP1 transcription factors bound to AC093818.1 in GC cells. Expression levels of the five lncRNAs, especially AC093818.1, were significantly upregulated in metastatic GC tissues relative to those in nonmetastatic GC tissues. AC093818.1 expression was correlated with invasion, lymphatic metastasis, distal metastasis, and tumor-node-metastasis stage. AC093818.1 expression was highly sensitive and specific in the diagnosis of metastatic or nonmetastatic GC. AC093818.1 overexpression promoted GC migration and invasion in vitro and in vivo. AC093818.1 overexpression increased PDK1, p-AKT1, and p-mTOR expression levels. AC093818.1 silencing decreased these expressions. AC093818.1 bound to transcription factors STAT3 and SP1, and SP1 or STAT3 silencing could alleviated the effect of AC093818.1 overexpression. The data demonstrate that lncRNA AC093818.1 accelerates gastric cancer metastasis by epigenetically promoting PDK1 expression. LncRNA AC093818.1 may be a potential therapeutic target for metastatic GC.

Laparoscopic Hyperthermic Intraperitoneal Perfusion Chemotherapy for Patients With Malignant Ascites Secondary to Unresectable Gastric Cancer.

BACKGROUND: To compare the efficacy of 3 chemotherapeutic combinations for laparoscopic hyperthermic intraperitoneal perfusion chemotherapy (HIPPC) in the treatment of malignant ascites secondary to unresectable gastric cancer (GC). MATERIALS AND METHODS: From January 2010 to December 2013, 38 GC patients were randomly divided into 3 groups and treated by laparoscopic HIPPC with 1 of the 3 following chemotherapy combinations: raltitrexed (Ra) with oxaliplatin (L-OHP), Ra with cisplatin (DDP), and Ra with mitomycin C (MMC). Perioperative complications, patients' quality of life, and survival were recorded and compared among the 3 groups. RESULTS: The intraoperative course was successful in all patients, and no perioperative death or complication related to laparoscopic HIPPC was documented. The median follow-up period was 9 months and the median survival was 7.5 months for all patients. Patients in the Ra/L-OHP group had a median survival of 8.7 months, the Ra/DDP group had a median survival of 5.6 months, and the Ra/MMC group had a median survival of 7.5 months. Patients' median survival in the Ra/L-OHP group and Ra/MMC group is significantly longer than Ra/DDP group (P<0.05). No significant difference was found in total remission rate of ascites, increase in the Karnofsky performance scale, and incidence rate of port-site metastases among the 3 groups. CONCLUSIONS: Laparoscopy-assisted HIPPC provide modest yet encouraging efficacy for malignant ascites secondary to disseminated GC. Our preliminary data indicate that the chemotherapeutical combination of Ra/L-OHP and Ra/MMC might be more beneficial compared with Ra/DDP in terms of patients' survival.

Thermo-chemotherapy inhibits the proliferation and metastasis of gastric cancer cells via suppression of EIF5A2 expression.

PURPOSE: Thermo-chemotherapy (TCT) is a new approach for the treatment of cancer that combines chemotherapy with thermotherapy. In the present study, we investigated the relationship between eukaryotic translation initiation factor 5A2 (EIF5A2) and TCT sensitivity in gastric cancer (GC) to further illuminate the molecular mechanism underlying the effect of TCT on GC. METHODS: A TCT cell model was constructed, and EIF5A2 was silenced or overexpressed by infection with a lentivirus expressing either EIF5A2 or EIF5A2 shRNA. Then, RT-qPCR, Western blotting, and immunohistochemistry assays were performed to evaluate the changes in the expression levels of EIF5A2, c-myc, vimentin, and E-cadherin. Cell proliferation and xenograft assays were conducted to evaluate the effect on cell proliferation. Finally, wound-healing and Transwell invasion assays were performed to evaluate the effects on migration and invasion. RESULTS: TCT reduced EIF5A2 expression at both the mRNA and protein levels. It also inhibited cell proliferation, migration, and invasion, downregulated the expression of c-myc and vimentin, and increased the expression of E-cadherin in both MKN28 and MKN45 cells. Silencing of EIF5A2 enhanced the above effects of TCT on MKN28 and MKN45 cells, while overexpression of EIF5A2 had the opposite effects. In addition, EIF5A2 overexpression weakened the inhibitory effect of TCT on tumor growth in vivo as well as the effects on c-myc, vimentin, and E-cadherin. CONCLUSION: TCT inhibits GC cell proliferation and metastasis by suppressing EIF5A2 expression. Our results provide new insights into our understanding of the molecular mechanism underlying the effects of TCT in GC.

[Prevention and treatment of hepatitis B recurrence after liver transplantation].

OBJECTIVE: To investigate the effect of the regimen of lamivudine (LAM) combined with hepatitis B immunoglobulin (HBIG) in prevention and treatment of re-infection of hepatitis B virus (HBV) and recurrence of hepatitis B after orthotopic liver transplantation (OLT) for HBV related end stage liver disease. METHODS: The clinical data of 183 adult liver transplantation patients who lived more than 6 months and were followed up for 14.6 months with complete data were studied retrospectively. According to the HBV prevention strategy, these recipients were divided into two groups: group of pure LAM (n = 106) and group of LAM plus intramuscular injection of low dose HBIG (n = 77). RESULTS: The rate of HBsAg negative conversion 1 week after OLT of the LAM group was 82.10% (87/106), significantly lower than that of the LAM + HBIG group [94.81% (73/77), P = 0.010]. The rates of HBV reinfection, HB recurrence, and YMDD mutation of the lamivudine group were 16.98% (18/106), 11.32% (12/106), and 8.49% (9/106) respectively, all significantly higher than those of the LAM + HBIG group [6.49% (5/77), 2.60% (2/77), and 1.30% (1/77) respectively, P = 0.035, 0.028, and 0.035 respectively]. All the patients with YMDD mutation were treated with adefovir (ADF) with improvement. Analysis showed no obvious difference in the effect of LAM given intramuscularly or intravenously. CONCLUSION: The protocol of combination of LAM and HBIG is highly effective, safe, and cost-effective in preventing the recurrence of HBV after OLT. YMDD mutation can be treated by ADF with satisfactory results.

Long noncoding RNA LINC00673 epigenetically suppresses KLF4 by interacting with EZH2 and DNMT1 in gastric cancer.

Long non-coding RNAs (lncRNAs), a variety of transcripts without protein coding ability, have recently been reported to play vital roles in gastric cancer (GC) development and progression. However, the biological role of long non-coding RNA LINC00673 in GC is not fully known. In the study, we found that LINC00673 expression was dramatically higher in gastric cancer tissues compared with adjacent normal tissues, and positively associated with lymph node metastasis, distant metastasis and TNM stage in patients. Higher LINC00673 expression predicted poor disease-free survival (DFS) and overall survival (OS) in GC patients. By univariate and multivariate Cox analysis, the results confirmed that higher LINC00673 expression was an independent risk factor of prognosis in patients. Knockdown of endogenous LINC00673 significantly inhibited cell proliferation, colony formation number, cell migration and invasion in GC. Furthermore, knockdown of endogenous LINC00673 reduced the expression levels of PCNA, CyclinD1 and CDK2 in GC cells. RNA immunoprecipitation (RIP) and chromatin immunoprecipitation (ChIP) proved that LINC00673 suppressed KLF4 expression by interacting with EZH2 and DNMT1 in GC cells. Moreover, we confirmed that LINC00673 promoted cell proliferation and invasion by partly repressing KLF4 expression in GC. Taken together, these results indicated that LINC00673 may be a prognostic biomarker and therapeutic target for GC patients.

Laparoscopic Hyperthermic Intraperitoneal Perfusion Chemotherapy for Patients with Malignant Ascites Secondary to Unresectable Gastric Cancer.

BACKGROUND: To compare the efficacy of three chemotherapeutic combinations for laparoscopic hyperthermic intraperitoneal perfusion chemotherapy (HIPPC) in the treatment of malignant ascites secondary to unresectable gastric cancer (GC). MATERIALS AND METHODS: From January 2010 to December 2013, 38 GC patients were randomly divided into three groups and treated by laparoscopic HIPPC with one of the three following chemotherapy combinations: raltitrexed (Ra) with oxaliplatin [trans-(±)-diaminocyclohexane oxalatoplatinum (l-OHP)], Ra with cisplatin (DDP), and Ra with mitomycin C (MMC). Perioperative complications, patients' quality of life, and survival were recorded and compared among the three groups. RESULTS: The intraoperative course was successful in all patients, and no perioperative death or complication related to laparoscopic HIPPC was documented. The median follow-up period was 9 months, and the median survival was 7.5 months for all patients. Patients in the Ra/l-OHP group had a median survival of 8.7 months, the Ra/DDP group had a median survival of 5.6 months, and the Ra/MMC group had a median survival of 7.5 months. Patients' median survival in the Ra/l-OHP group and Ra/MMC group was significantly longer than in the Ra/DDP group (P < .05). No significant difference was found in total remission rate of ascites, increase in the Karnofsky Performance Scale, and incidence rate of port-site metastases among the three groups. CONCLUSIONS: Laparoscopy-assisted HIPPC provides modest yet encouraging efficacy for malignant ascites secondary to disseminated GC. Our preliminary data indicate that the chemotherapeutic combination of Ra/l-OHP and Ra/MMC might be more beneficial compared with Ra/DDP in terms of patients' survival.

MicroRNA-218 is upregulated in gastric cancer after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy and increases chemosensitivity to cisplatin.

AIM: To investigate the molecular mechanisms of miRNA in advanced gastric cancers (AGCs) before and after cytoreductive surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: A miRNA microarray containing human mature and precursor miRNA sequences was used to compare expression profiles in serum samples of 5 patients with AGC before and after CRS + HIPEC. The upregulation of miR-218 was confirmed by real-time reverse transcription polymerase chain reaction and its expression was analyzed in SGC7901 gastric cancer cells. RESULTS: miRNA microarray chip analysis found that the level of miR-218 expression was upregulated more than 8 fold after CRS + HIPEC. Furthermore, miR-218 increased gastric cancer cell chemosensitivity to cisplatin in vitro and inhibited gastric cell tumor growth in nude mice in vivo (0.5 vs 0.78, P < 0.05). CONCLUSION: Our results indicated that targeting miR-218 may provide a strategy for blocking the development of gastric cancer and reverse the multi-drug resistance of gastric cell lines.

[Literature review of the efficacy and safety of hyperthermic intraperitoneal perfusion chemotherapy after cytoreductive surgery in the treatment of pseudomyxoma peritonei].

OBJECTIVE: To evaluated the safety and efficacy of hyperthermic intraperitoneal perfusion chemotherapy(HIPC) in the prevention and treatment of pseudomyxoma peritonei (PMP) recurrence after cytoreductive surgery(CRS). METHODS: Studies published in English before 2010 on HIPC after CRS for PMP were searched in PubMed database. Each study was carefully evaluated based on pre-determined criteria. Study results were comprehensively displayed in a form. A descriptive systematic review was performed. RESULTS: A total of 11 studies were included. The median survival time of patients in these studies ranged from 25.6 months to 156 months. The ranges of 1-year, 2-year, 3-year, 5-year, and 10-year survival rates were 72%-100%, 55%-96%, 59%-96%, 52%-96%, and 55%-96%, respectively. The overall complication rate ranged from 2%-15%, and the total perioperative mortality were from 0 to 7%. CONCLUSION: HIPC after CRS is effective and safe for patients with PMP.

Chemotherapy with laparoscope-assisted continuous circulatory hyperthermic intraperitoneal perfusion for malignant ascites.

AIM: To investigate the procedure, feasibility and effects of laparoscope-assisted continuous circulatory hyperthermic intraperitoneal perfusion chemotherapy (CHIPC) in treatment of malignant ascites induced by peritoneal carcinomatosis from gastric cancers. METHODS: From August 2006 to March 2008, the laparoscopic approach was used to perform CHIPC on 16 patients with malignant ascites induced by gastric cancer or postoperative intraperitoneal seeding. Each patient underwent CHIPC three times after laparoscope-assisted perfusion catheters placing. The first session was completed in operative room under general anesthesia, 5% glucose solution was selected as perfusion liquid, and 1500 mg 5-fluorouracil (5-FU) and 200 mg oxaliplatin were added in the perfusion solution. The second and third sessions were performed in intensive care unit, 0.9% sodium chloride solution was selected as perfusion liquid, and 1500 mg 5-FU was added in the perfusion solution alone. CHIPC was performed for 90 min at a velocity of 450-600 mL/min and an inflow temperature of 43 +/- 0.2 degrees C. RESULTS: The intraoperative course was uneventful in all cases, and the mean operative period for laparoscope-assisted perfusion catheters placing was 80 min for each case. No postoperative deaths or complications related to laparoscope-assisted CHIPC occurred in this study. Clinically complete remission of ascites and related symptoms were achieved in 14 patients, and partial remission was achieved in 2 patients. During the follow-up, 13 patients died 2-9 mo after CHIPC, with a median survival time of 5 mo. Two patients with partial remission suffered from port site seeding and tumor metastasis,and died 2 and 3 mo after treatment. Three patients who are still alive today survived 4, 6 and 7 mo, respectively. The Karnofsky marks of patients (50-90) increased significantly (P < 0.01) and the general status improved after CHIPC. Thus satisfactory clinical efficacy has been achieved in these patients treated by laparoscopic CHIPC. CONCLUSION: Laparoscope-assisted CHIPC is a safe, feasible and effective procedure in the treatment of debilitating malignant ascites induced by unresectable gastric cancers.

Resection of a giant hepatocellular carcinoma weighing over ten kilograms.

The authors report a giant hepatocellular carcinoma (HCC) with a diameter over 30 cm and weight over 10 kg that was resected completely. A 62-year-old man was admitted because of continuous abdominal uplift. A computed tomography scan demonstrated that the entire abdomen was filled with a giant tumor containing both cystic and solid components with a size of 29 cm x 22 cm. The huge tumor was successfully resected without any complication, such as massive hemorrhage or visceral injuries. The size and weight of the tumor were 35 cm x 30 cm x 15 cm and 10 050 g, respectively. Pathological examination showed that the tumor was a well-differentiated HCC, and alpha-fetoprotein was positive. Postoperative syndrome, characterized by hypovolemic shock, diarrhea and urine retention, was observed and induced by abdominal decompression. This syndrome was resolved with expectant treatment. The patient was still alive without recurrence after a 27-mo follow-up.
