FIRST STEP VIEW OF THE EFFICACY OF ANTINEOPLASTIC AGENTS

A human K562 leukaemia call and acute adult leudaemia patient samples have been used to test the efficacy of antineoplastic agents with MTT assay.All 18 drugs were invoved.According to the purpose of experiment these durgs were applied at different opportunities or combinations.The drug efficacy has been observed and summarized as four different conditions:1.the change of the time(△ T )closely related with drug effacacy, during the duration the change of drug concentration(△ C) at certain extent has almost no influence; 2the △ C closely related with the efficacy, the △ T has no influence;3. The △ C and △ T effect the results together;and 4.the △ C and △ T effect not the result. And then draw a conclution that the process or drug effacacy has a multiple function with flat distrtct.

PERCUTANEOUS INJECTING ANTINEOPLASTIC AGENT INTO TRANSPLANTED TUMORS OF MICE BY CT－GUIDED

Antineoplastic agent and contrast medium were injected into transplanted tumors of mice under guidance with CT, site and range of the intratumoural drug were shown on CT image immediately. It was value of multipoint injections, concentration of 0.1 mg/0.l ml MMC every point, 1 cm interval of injection. After the injections, the tumor size of mice reduced and at last disappeared (ratio of inhibited tumor 59.32% in 0.05 mg MMC group, 43.86% in 0.1 mg MMC group).The pathologic examination showed coagulatic necrosis of the tumor tissues. The higher concentration of antineoplastic agent (0.2 mg MMC) could make the tumors enlarged (ratio of inhibited tumor -15.3%). The tissues and vessels around the tumors were not injured, if MMC overflow out off the tumor.

Radiomics in Antineoplastic Agents Development:Application and Challenge in Response Evaluation

The recent spring up of the antineoplastic agents and the prolonged survival bring both challenge and chance to radiological practice.Radiological methods including CT,MRI and PET play an increasingly important role in evaluating the efficacy of these antineoplastic drugs.However,different antineoplastic agents potentially induce different radiological signs,making it a challenge for radiological response evaluation,which depends mainly on one-sided morphological response evaluation criteria in solid tumors(RECIST)in the status quo of clinical practice.This brings opportunities for the development of radiomics,which is promising to serve as a surrogate for response evaluations of anti-tumor treatments.In this article,we introduce the basic concepts of radiomics,review the state-of-art radiomics researches with highlights of radiomics application in predictions of molecular biomarkers,treatment response,and prognosis.We also provide in-depth analyses on major obstacles and future direction of this new technique in clinical investigations on new antineoplastic agents.

背景:间充质干细胞来源外泌体具有免疫原性低且肿瘤归巢能力强等优点,在靶向递送药物方面备受关注。但外泌体在到达靶细胞前易被体内循环迅速清除,此外,由于外泌体表面性质和摄取机制复杂,其靶向性并不十分明显,需要一定的工程化策略提高递送效率。目的:通过综述间充质干细胞来源外泌体工程化修饰的不同策略,了解提高外泌体递送效率的相关机制、临床前应用和面临的问题,为进一步临床应用提供理论依据。方法:检索中国知网、维普、万方、PubMed数据库从建库至2024年的相关文献,检索词为“间充质干细胞,外泌体,工程化外泌体,靶向递送,抗肿瘤药物”和“mesenchymal stem cells,exosomes,engineered exosomes,targeted delivery,antineoplastic agents”,筛选工程化间充质干细胞来源外泌体靶向递送抗肿瘤药物的文献,共计纳入85篇文献进行综述分析。结果与结论:(1)间充质干细胞来源外泌体的工程化修饰复杂多样,可通过显著增强外泌体对器官或组织靶向能力,增加血液循环中停留时间,以及降低外泌体中促肿瘤分子的表达,以此达到提高外泌体递送效率的效果;(2)间充质干细胞外泌体在目前的抗肿瘤治疗研究中递送传统和新型药物具有巨大前景;(3)当前仍然存在一些安全问题不能将其转化在临床中,未来的研究将进一步改进和深入研究递送机制,有望开发出更为高效和安全的治疗策略。

枯草芽孢杆菌中一个受二硫键还原剂诱导并与伸长因子Tu同源的蛋白质

分析了β-巯基乙醇（β-ME）和二硫苏糖醇（DTT）对枯草芽孢杆菌（Bacillussubtilis细胞蛋白质组分的影响。在LB培养基中，β-ME和DTT处理能诱导一个50kD蛋白质（P50）的合成。在正常生长条件下P50是一个组成性（constitutive）成的细胞质蛋白质。热激也能诱寻P50，但是孢子形成（sporulation）不能诱导P50。在Schaeffer孢子形成培养基中，β-ME和DTT都不能诱导P5O，表明二硫键还原剂诱导P50的能力依赖于特定的生理条件。用VS蛋白酶有限降解P50，得到4个主要的多肽片段，测定了其中两个片段的N-端氨基酸序列。同源性检索发现P50高度同源于蛋白质合成的伸长因子Tu。

Multimodality treatment in hepatocellular carcinoma patients with tumor thrombi in portal vein

AIM: To compare the therapeutic effect and significances of multimodality treatment for hepatocellular carcinoma (HCC) with tumor thrombi in portal vein (PVTT). METHODS: HCC patients (n=147) with tumor thrombi in the main portal vein or the first branch of portal vein were divided into four groups by the several therapeutic methods. There were conservative treatment group in 18 out of patients (group A); and hepatic artery ligation(HAL) and/or hepatic artery infusion (HAI) group in 18 patients (group B), in whom postoperative chemoembolization was done periodically; group of removal of HCC with PVTT in 79 (group C) and group of transcatheter hepatic arterial chemoembolization (TACE) or HAI and/or portal vein infusion (PVI) after operation in 32 (group D). RESULTS: The median survival period was 12 months in our series and the 1-,3-, and 5-year survival rates were 44.3%, 24.5% and 15.2%, respectively. The median survival times were 2, 5, 12 and 16 months in group A, B, C and D, respectively. The 1-, 3- and 5-year survival rates were 5.6%, 0% and 0% in group A; 22.2%, 5.6% and 0% in group B; 53.9%, 26.9% and 16.6% in group C; 79.3%, 38.9% and 26.8% in group D, respectively. Significant difference appeared in the survival rates among the groups (P 【 0.05). CONCLUSION: Hepatic resection with removal of tumor thrombi and HCC should increase the curative effects and be encouraged for the prolongation of life span and quality of life for HCC patients with PVTT, whereas the best therapeutic method for HCC with PVTT is with regional hepatic chemotherapy or chemoembolization after hepatic resection with removal of tumor thrombi.

Experimental study on antitumor effect of arsenic trioxide in combination with cisplatin or doxorubicin on hepatocellular carcinoma

INTRODUCTIONThe main component of a traditional Chinese drug 'Pishuang'. arsenic trioxide (As2O3), has obviously selective anti-tumor effect on human hepatocellular carcinoma (HCC)in both in vitro and in vivo studies[1-5]. Due to limited effectiveness when any anti-carcinogen is used alone and obviously increased toxicity when the dose is raised, there is no exception for As2O3. Furthermore, combined chemotherapy contributes to improve therapeutic effectiveness, disperse toxicity and surmount drug-resistance,in which the combination of traditional Chinese and modern medicine has more advantages and characteristics. As a result,we made an experimental study on anti-tumor effect of As2O3in combination with cisplantin (PDD) or doxorubicin (ADM)on HCC. to investigate the possibility of AS2O3 in combination with PDD or ADM and nature of interaction between them,and to provide experimental basis for clinical application.

Sulforaphane as a Promising Natural Molecule for Cancer Prevention and Treatment

Tumorigenicity-inhibiting compounds have been identifled in our daily diet.For example,isothiocyanates(ITCs)found in cruciferous vegetables were reported to have potent cancer=prevention activities.The best characterized ITC is sulforaphane(SF).SF can simultaneously modulate multiple cellular targets involved in carcinogenesis,including(1)modulating carcinogen-metabolizing enzymes and blocking the action of mutagens;(2)inhibition of cell proliferation and induction of apoptosis;and(3)inhibition of neo-angiogenesis and metastasis.SF targets cancer stem cells through modulation of nuclear factor kappa B(NF-κB),Sonic hedgehog(SHH),epithelial-mesenchymal transition,and Wnt/βcatenin pathways.Conventional chemotherapy/SF combination was tested in several studies and resulted in favorable outcomes.With its favorable toxicological profile,SF is a promising agent in cancer prevention and/or therapy.In this article,we discuss the human metabolism of SF and its effects on cancer prevention,treatment,and targeting cancer stem cells,as well as providing a brief review of recent human clinical trials on SF.

Animal experiment and clinical study of effect of gamma-interferon on hepatic fibrosis

AIM: To evaluate the antifibrotic effect of different doses of recombinant human Gamma-Interferon (IFN-gamma) in two rat models of hepatic fibrosis, and to observe its effect on moderate chronic hepatitis B virus fibrosis. METHODS: Hepatic fibrosis was successfully induced in 150 and 196 rats by subcutaneous injection of carbon tetrachloride (CCl4) and intraperitoneal injection of dimethylnitrosamine (DMN), respectively. Each of the two model groups was divided into: (1) fibrotic model group; (2) colchicine treatment group (0.1 mg/kg/day, gastrogavage for 8 weeks); (3) high-dose IFN-gamma group (15 MU/kg per day, i.m. for 8 weeks); (4) medium-dose IFN-gamma group (5 MU/kg daily, i.m. for 8 weeks); and (5) Y low-dose IFN-gamma group (1.67 MU/kg daily, i.m. for 8 weeks). Another group of 10 rats without any treatment was used as normal controls. At the end of the experiment, semi-quantitative histopathological scores of inflammation and fibrosis, liver alpha smooth muscle actin (alpha-SMA) expression level, liver hydroxyl proline content and serum hyaluronic acid levels were compared. And 47 medium chronic hepatitis B viral fibrosis patients were studied. They were given IFN-gamma treatment, 100 MU/day i.m. for the first three months and 100 MU qod i.m. for the next six months. Semi-quantitative pathological scores of inflammation and fibrosis and serum hepatic fibrosis indices were compared within the 9 months. RESULTS: In animal experiment, the pathological fibrosis scores and liver hydroxyl proline content were found to be significantly lower in rats treated with different doses of IFN-gamma as compared with rats in fibrotic model group induced by either CCl4 or DMN, in a dose-dependent manner. For CCl4-induced model, pathological fibrosis scores in high, medium and low doses IFN-gamma groups were 5.10 +/- 2.88, 7.70 +/- 3.53 and 8.00 +/- 3.30, respectively, but the score was 14.60 +/- 7.82 in fibrotic model group. Hydroxyl proline contents were 2.83 +/- 1.18, 3.59 +/- 1.22 and 4.80 +/- 1.62, in the three IFN-gamma groups, and 10.01 +/- 3.23 in fibrotic model group. The difference was statistically significant (P【0.01). Similar results were found in DMN-induced model. Pathological fibrosis scores were 6.30 +/- 0.48, 8.10 +/- 2.72 and 8.30 +/- 2.58, in high, medium and low doses IFN-gamma groups, and 12.60 +/- 3.57 in fibrotic model group. Hydroxyl proline contents were 2.72 +/- 0.58, 3.14 +/- 0.71 and 3.62 +/- 1.02, in the three IFN-gamma groups, and 12.79 +/- 1.54 in fibrotic model group. The difference was statistically significant (P【0.01).Serum hepatic fibrosis indices decreased significantly in the 47 patients after IFN-gamma treatment (HA: 433.38 +/- 373.00 vs 281.57 +/- 220.48; LN: 161.22 +/- 41.02 vs 146 +/- 35 +/- 44. 67; PC III: 192.59 +/- 89.95 vs 156.98 +/- 49.22; C-I: 156.30 +/- 44.01 vs 139.14 +/- 34.47) and the differences between the four indices were significant (P 【0.05). Thirty-three patients received two liver biopsies, one before and one after IFN-gamma treatment. In thirty of 33 patients IFN-gamma had better effects according to semi-quantitative pathological scores (8.40 +/- 5.83 vs 5.30 +/- 4.05, P【0.05). CONCLUSION: All the three doses of IFN-gamma are effective in treating rat liver fibrosis induced by either CCl4 or DMN, the higher the dose, the better the effect. And IFN-gamma is effective for patients with moderate chronic hepatitis B viral fibrosis.

Adeno-associated virus mediated endostatin gene therapy in combination with topoisomerase inhibitor effectively controls liver tumor in mouse model

AIM:rAAV mediated endostatin gene therapy has been examined as a new method for treating cancer.However, a sustained and high protein delivery is required to achieve the desired therapeutic effects.We evaluated the impact of topoisomerase inhibitors in rAAV delivered endostatin gene therapy in a liver tumor model. METHODS:rAAV containing endostatin expression cassettes were transduced into hepatoma cell lines.To test whether the topoisomerase inhibitor pretreatment increased the expression of endostatin,Western blotting and ELISA were performed.The biologic activity of endostatin was confirmed by endothelial cell proliferation and tube formation assays. The anti-tumor effects of the rAAV-endostatin vector combined with a topoisomerase inhibitor,etoposide,were evaluated in a mouse liver tumor model. RESULTS:Topoisomerase inhibitors,including camptothecin and etoposide,were found to increase the endostatin exPression level in vitro.The over-expressed endostatin, as a result of pretreatment with a topoisomerase inhibitor, was also biologically active.In animal experiments,the combined therapy of topoisomerase inhibitor,etoposide with the rAAV-endostatin vector had the best tumor- suppressive effect and tumor foci were barely observed in livers of the treated mice.Pretreatment with an etoposide increased the level of endostatin in the liver and serum of rAAV-endostatin treated mice.Finally,the mice treated With rAAV-endostatin in combination with etoposide showed the longest survival among the experimental models. CONCLUSION:rAAV delivered endostatin gene therapy in combination with a topoisomerase inhibitor pretreatment is an effective modality for anticancer gene therapy.

PURPOSE: To observe the effects of electroacupuncture therapy on T cells and activity of NK cell in the patient of Chemotherapy. METHOD: Electro-acupuncture therapy was simultaneously applied during chemotherapy, T cells and activity of NK cell of patients were determined before electroacupuncture treatment (before chemotherapy) and after 4-course electro-acupuncture treatments. RESULTS: Before chemotherapy, CD3 was low within the normal range, CD4 was much lower than the normal range, and CD8, CD4/CD8 and activity of NK cell were within the normal range. After one month of chemotherapy combined with electro-acupuncture, no decline of all the indices was found (P > 0.05). CONCLUSION: Electro-acupuncture can really increase the immune function of patients of chemotherapy.

Effects of aminoguanidine on nitric oxide production induced by inflammatory cytokines and endotoxin in cultured rat hepatocytes

AIM: To study the effects of aminoguanidine (AG) and two L-arginine analogues N(omega)-nitro-L-arginine methyl ester (L-NAME) and N(omega)-nitro-L-arginine (L-NNA) on nitric oxide (NO) production induced by cytokines (TNF-alpha, IL-1 beta, and IFN-gamma) and bacterial lipopolysaccharide (LPS) mixture (CM) in the cultured rat hepatocytes, and examine their mechanisms action. METHODS: Rat hepatocytes were incubated with AG, L-NAME, L-NNA, Actinomycin D (ActD) and dexamethasone in a medium containing CM (LPS plus TNF-alpha, IL-1 beta, and IFN-gamma) for 24h. NO production in the cultured supernatant was measured with the Griess reaction. Intracellular cGMP level was detected with radioimmunoassy. RESULTS: NO production was markedly blocked by AG and L-NAME in a dose-dependent manner under inflammatory stimuli condition triggered by CM in vitro. The rate of the maximum inhibitory effects of L-NAME (38.9%) was less potent than that obtained with AG(53.7%, P 【 0.05). There was no significant difference between the inhibitory effects of AG and two L-arginine analogues on intracellular cGMP accumulation in rat cultured hepatocytes. Non-specific NOS expression inhibitor dexamethasone (DEX)and iNOS mRNA transcriptional inhibitor ActD also significantly inhibited CM-induced NO production. AG(0.1 mmol x L(-1)) and ActD (0.2 ng x L(-1)) were equipotent in decreasing NO production induced by inflammatory stimuli in vitro, and both effects were more potent than that induced by non-selectivity NOS activity inhibitor L-NAME (0.1 mmol x L(-1)) under similar stimuli conditions (P【0.01). CONCLUSION: AG is a potent selective inhibitor of inducible isoform of NOS,and the mechanism of action may be not only competitive inhibition in the substrate level, but also the gene expression level in rat hepatocytes.

Enzyme Dynamic Study on Calmodulin Ca^(++)-Mg^(++)-ATPase System of Red Blood Cells Inhibited byα-anordrin and Probimane

To clarify the possible mechanisms of α anordin and probimane on calmodulin Ca ++ Mg ++ APTase system, enzyme dynamic study was carried out by determining three dynamic parameters [the substrate concentration(ATP) response curve, dose(inhibitors) response curve and time response curve]. Our data have shown that the inhibitory rates of α anordrin and probimane are unrelated to substrate(APT) concentrations, but related to calmodulin concentrations. The inhibition of α anordrin and probimane is very quick that is completed within 1 to 5 min and can maintain more than 1 hr in the same inhibitory rates. So it is possible that α anordrin and probimane are calmodulin competitors with calmodulin like binding whose actions can occur by affecting the reaction balance of substrate and product on target enzymes of calmodulin( Ca ++ Mg ++ ATPase).

Advances in the Researches on the Blocking Effect of Chinese Drugs on Tumors

Malignant tumors are caused by multiple carcinogenic factors undergoing several stages. The occurrence and development of tumors may be prevented and blocked if some effective interference factors are brought into play.1 At present, there are two main subjects for the researches, that is, blocking the precancerous lesions and blocking the develop-ment of tumors. The former focuses on the removing of carcinogenic factors and on the chemoprophylaxis of cancer, while the latter on the inhibition of cancer cell infiltration and cancerometastasis. These are summarized as follows.

Interferon plus ribavirin and interferon alone in preventing hepatocellular carcinoma: A prospective study on patients with HCV related cirrhosis

AIM:To determine the role of interferon(IFN)with or withoutribavirin in preventing or delaying hepatocellular carcinoma(HCC)development in patients with hepatitis C virus(HCV)related cirrhosis.Data on the preventive effect of IFN plusribavirin treatment are lacking.METHODS:A total of 101 patients(62 males and 39 females,mean age 55.1±1.4 years)with histologically proven HCVrelated liver cirrhosis plus compatible biochemistry andultrasonography were enrolled in the study.Biochemistryand ultrasonography were performed every 6 mo.Ultrasoundguided liver biopsy was performed on all detected focallesions.Follow-up lasted for 5 years.Cellular proliferation,evaluated by measuring Ag-NOR proteins in hepatocytesnuclei,was expressed as AgNOR-Proliferative index(AgNOR-PI)(cut-off=2.5).Forty-one patients(27 males,14 females)were only followed up after the end of anyearly treatment with IFN-alpha2b(old treatment controlgroup=OTCG).Sixty naive patients were stratified accordingto sex and AgNOR-PI and then randomized in two groups:30 were treated with IFN-alpha2b+ribavirin(treatmentgroup=TG),the remaining were not treated(control group=CG).Nonresponders(NR)or relapsers in the TG receivedfurther IFN/ribavirin treatments after a 6 mo of withdrawal.RESULTS:AgNOR-PI was significantly lowered by IFN(P<0.001).HCC incidence was higher in patients withAgNOR-PI>2.5(26% vs3%,P<0.01).Two NR in the OTCG,none in the TG and 9 patients in the CG developed HCCduring follow-up.The Kaplan-Mayer survival curves showedstatistically significant differences both between OTCG andCG(P<0.004)and between TG and CG(P<0.003).CONCLUSION:IFN/ribavirin treatment associated with re-treatment courses of NR seems to produce the best resultsin terms of HCC prevention.AgNOR-PI is a useful markerof possible HCC development.
