目的 分析促红细胞生成素（EPO）及促红细胞生成素受体（EPOR）在肝细胞癌（NCC）以及正常组织中的表达规律,以及它们和肝细胞癌微血管密度（MVD）之间的关系。方法 选取我院手术切除的肝细胞肝癌的标本30例,取肿瘤边缘2.0 cm的肝组织作为对照,同时取正常肝脏组织10例做为阴性对照。利用酶联免疫吸附实验（ELISA）检测各组织中EPO及EPOR表达水平,利用免疫组织化学方法染色检测微血管密度（MVD）。对比癌组织和癌旁组织EPO、EPOR及MVD差异,分析NCC中EPO、EPOR、MVD与肿瘤病理特征的关系,分析EPO、EPOR表达水平与MVD之间的关系。结果 HCC组织中,EPR、EPOR、MVD均高于癌旁组织和正常组织,差异有统计学意义（P<0.001）,EPR、EPOR、MVD在癌旁组织和正常组织中,差异无统计学意义（P>0.05）。肿瘤大小>5 cm、存在包膜侵犯、存在远处转移以及高中分化的HCC中,EPR、EPOR、MVD水平高于肿瘤大小≤5 cm、无包膜侵犯、无远处转移以及低分化的水平,差异有统计学意义（P<0.05）。Person相关分析结果显示,EPO表达水平与MVD的相关系数r=0.651（P<0.001）,EPOR表达水平与MVD的相关系数r=0.620（P<0.001）。结论 EPO、EPOR、MVD在HCC中呈现高水平,且与肿瘤大小、局部侵犯、远处转移及分化程度有关,其机制可能与EPO、EPOR增加MVD有关。

Objective To analyze the expression of erythropoietin （EPO） and erythropoietin receptor （EPOR） in hepatocellular carcinoma （NCC） and normal tissues,and their relationship with hepatocyte microvessel density （MVD）. Methods Thirty specimens of hepatocellular carcinoma hepatectomy were selected from our hospital. The liver tissue at the edge of the tumor was taken as a control,and 10 cases of normal liver tissue were used as a negative control. The expression levels of EPO and EPOR in each tissues were detected by enzyme-linked immunosorbent assay （ELISA）,and microvessel density （MVD） was detected by immunohistochemistry. The differences of EPO,EPOR and MVD between each tissues were compared. The relationship between EPO,EPOR,MVD and tumor pathological features in NCC was analyzed. The relationship between EPO and EPOR expression levels and MVD was analyzed. Results In HCC tissues,EPR,EPOR and MVD were higher than those in adjacent tissues and normal tissues. The difference was statistical difference （P<0.001）. EPR,EPOR and MVD were not statistically significant in adjacent tissues and normal tissues. P>0.05）. The levels of EPR,EPOR,and MVD in tumors with tumor size >5 cm,invasion of the capsule,distant metastasis,and high-differentiation were higher than those of tumor size ≤ 5 cm,no capsule invasion,no distant metastasis,and poor differentiation. The difference was statistical difference （P < 0.05）. Person correlation analysis showed that the correlation coefficient between EPO expression level and MVD was r=0.651 （P<0.001）,and the correlation coefficient between EPOR expression level and MVD was r=0.620 （P<0.001）. Conclusion EPO,EPOR and MVD are highly expressed in HCC,and are related to tumor size,local invasion,distant metastasis and differentiation. The mechanism may be related to EPO and EPOR increasing MVD.

肝细胞肝癌(HCC)是世界上最常见的肿瘤之一,其病因及确切的分子机制尚不完全清楚,目前认为其发病是多因素、多步骤的复杂过程,且预后较差。miRNAs在调控细胞的周期变化中起到重要的作用,它具有较高的组织特异性,在肿瘤发生中起到关键作用,从而有潜力作为肝癌的诊断和分类的新生物标志物,以及预测患者预后的工具。本文就近年来miRNAs在肝细胞肝癌方面的研究进展做一综述。

Objective To evaluate the effect of LCVP applied during the operation of hepatectomy.Methods Sixty patients underwent hepatectomy were enrolled in the study from March 2010 to March 2012 in our hospital which were randomized into LCVP group and normal CVP (NCVP) group by the sealed envelope method. CVP was kept<0.5 kPa during entire procedure of hepatectomy in LCVP group, and the value of CVP and blood pressure were controlled within 10% of the baseline. The same anesthesia, incision and hepatectomy technique and indications of blood transfusion in LCVP group were undertaken as those in NCVP group. Intraoperative CVP, blood pressure, HR and blood routine were recorded. The time of operation, the amount of bleeding, the extent of removed hepatic tissue, the amount of transfused blood products,liver and renal function index, and coagulation function index were detected on the 1st, 3rd and 7th day after operation. Also the supplement of albumin, the rate of postoperation complications and the length of hospital stay and the expense in hospital were recorded.Results ① The general clinical data of patients were similar in the two group (P>0.05). ② The operation time, total bleeding volume, bleeding volume and RBC infusion volume in LCVP group were significantly lower than those in group NCVP (P<0.05). ③ There were no significant difference of postoperative liver and renal function index between the two groups (P>0.05). But the supplement of albumin in LCVP group after operation was significant less than that in NCVP group (P<0.05). ④ There were no significant difference of the postoperative complication, the length of hospital stay and the expense in hospital between the two groups (P>0.05).Conclusions The application of LCVP in hepatectomy cause less blood loss, shorten the length of hospital stay and decrease the expense in hospital, which is beneficial for the postoperative recovery.

Objective To explore the status and influencing factors of nausea and vomiting after radical resection of liver cancer. Methods A retrospective analysis was conducted on 70 liver cancer patients admitted to the Second People’s Hospital of Tianjin from May 2022 to May 2024. All patients underwent radical surgery for liver cancer,and their postoperative nausea and vomiting conditions were analyzed. According to the occurrence of nausea and vomiting, 30 patients who experienced nausea and vomiting after surgery were divided into an observation group, and the remaining 40 patients were divided into a control group. The clinical and pathological characteristics as well as perioperative indicators between two groups of patients were compared. A logistic regression model was established to analyze the influencing factors of postoperative nausea and vomiting in liver cancer patients after surgical resection,with postoperative nausea and vomiting as the dependent variable. Results The incidence of postoperative nausea and vomiting in liver cancer patients was 42. 86%（30/70）, including 14 cases of grade I, accounting for 20. 00%, 10 cases of grade II, accounting for 14. 29%, four cases of grade III,accounting for 5. 71%, and two cases of grade IV,accounting for 2. 86%. There were no significant differences in gender,body mass index（BMI）, pathological type,clinical stage,and preoperative fasting time between the observation group and the control group（P>0. 05）. However, there were significant differences in age and chemotherapy status between the observation group and the control group（P<0. 05）. There were no significant differences in the operation time,postoperative VAS score,anesthesia method and postoperative complications between the observation group and the control group（P>0. 05）, but with differences in the portal block time,intraoperative blood loss and postoperative abdominal distension between the observation group and the control group（P<0. 05）. Age, chemotherapy, intraoperative blood loss, and postoperative abdominal distension were independent influencing factors for postoperative nausea and vomiting in liver cancer patients undergoing surgical resection（P<0. 05）. Conclusions The incidence of nausea and vomiting after surgical resection in liver cancer patients is relatively high, with age, chemotherapy, intraoperative blood loss, and postoperative abdominal distension may be influencing factors for nausea and vomiting. Therefore, relevant measures should be taken in a timely manner to intervene in high-risk patients to prevent postoperative nausea and vomiting and reduce its severity.

       目的   探讨多梳蛋白SUZ12对肝细胞肝癌（HCC）细胞增殖、血管生成拟态形成和人脐静脉内皮细胞（HUVECs）血管生成的影响。方法 分别利用MTT比色法及体外血管生成实验检测SUZ12表达水平改变对HCC细胞SMMC-7721、Hep3B增殖、血管生成拟态形成和HUVECs血管生成的影响。结果  MTT结果显示，在HCC细胞中分别敲低或过表达SUZ12均对HCC细胞的增殖能力无明显影响。将SUZ12低表达HCC细胞与HUVECs共培养后，HCC细胞的血管生成拟态管样结构形成增多。此外，将SUZ12敲低组HCC细胞的培养上清用于培养HUVECs后，HUVECs的血管生成拟态管样结构形成也明显增多。结论  SUZ12对HCC细胞的增殖无影响，其在HCC中可抑制HCC细胞和HUVECs的血管生成拟态管样结构形成。上述结果提示SUZ12可能通过调控HCC细胞及HUVECs的血管生成发挥抑癌作用。
