目的: 观察裴氏软肝消痞丸(PRGXP)对荷H₂₂瘤小鼠血清TNF-α和IFN-γ的影响,探讨裴氏软肝消痞丸对荷瘤小鼠免疫系统的调节作用以及对肿瘤的抑制作用。
方法: 通过小鼠右前腋部皮下接种法,建立荷H₂₂(肝癌)实体瘤小鼠模型,随机平均分为空白组、模型对照组、裴氏软肝消痞丸大剂量组、裴氏软肝消痞丸中剂量组、裴氏软肝消痞丸小剂量组和复方斑蝥胶囊组。灌胃给药10d,末次给药后24h小鼠称重,摘除小鼠眼球采血,用干净试管收集血液,室温凝固2h,离心1500转10min,收集血清封装,-20℃冷冻保存。脊髓脱臼法处死,剥离肿瘤组织、胸腺、脾脏并称重,计算抑瘤率,测定胸腺指数(TI)及脾脏指数(SI)。用ELISA法测定荷瘤小鼠血清中TNF-α和IFN-γ的浓度。
结果:
① 裴氏软肝消痞丸大、中、小剂量组的平均瘤重均低于模型对照组,分别为(0.926±0.237)g、(0.776±0.122)g、(0.935±0.227)g,与模型对照组比较均有统计学意义(P<0.05),抑瘤率分别为24.5%、36.8%和23.9%。
② 裴氏软肝消痞丸大、中、小剂量组荷瘤小鼠的胸腺指数(TI)、脾脏指数(SI)均高于模型对照组,其中中剂量组TI为(53.2±15.6)mg/10g,较模型对照组增长31.4%,与模型对照组比较有统计学意义(P<0.05);中剂量组SI为(65.0±10.1)mg/10g,较模型对照组增长45.1%,与模型对照组比较有统计学意义(P<0.05)。
③ 裴氏软肝消痞丸(PRGXP)大、中、小剂量组TNF-α的浓度均较模型对照组升高,其中中剂量组TNF-α的浓度为(85.97±19.41)pg/ml,与模型对照组比较有统计学意义(P<0.05)。复方斑蝥胶囊组(BM)血清中TNF-α的浓度为(51.34±9.78)pg/ml,与模型对照组比较有统计学意义(P<0.05)。PRGXP中剂量组与BM组比较,有统计学意义(P<0.05)。
④ 裴氏软肝消痞丸(PRGXP)大、中剂量组IFN-γ的浓度均较模型对照组升高,其中中剂量组IFN-γ的浓度为(90.85±11.91)pg/ml,与模型对照组比较有统计学意义(P<0.05)。复方斑蝥胶囊组(BM)血清中IFN-γ的浓度为(66.73±11.76)pg/ml,与模型对照组比较有统计学意义(P<0.05)。PRGXP中剂量组与BM组比较,有统计学意义(P<0.05)。

ABSTRACT
Objective: After the observation of Peishiruanganxiaopiwan (PRGXP) on the serum TNF-α and IFN-γ in H₂₂ Tumor-bearing Mice, we have discussed the regulating and antitumor effects of PRGXP on the immune system of Tumor-bearing Mice.
Methods: Firstly, we established the tumor-bearing mice model by hypodermic inoculation in the right front axilla of mice. All the mice were divided into blank group, model group, great dose group of PRGXP, middle dose group of PRGXP, little dose group of PRGXP and FufangBanmao capsule (BM) group. Every group was dosed for ten days. After 24h of the last dose, the eyeballs of the mice were extirpated for blood collection with clean test tube. The blood was solidified for 2 hours at room temperature, and then centrifuged 1500 rpm for 10 minutes. The serum was collected, packaged and saved at −20°C. And then we measured the density of the TNF-α and IFN-γ in H₂₂ Tumor-bearing Mice using the ELISA method. Lastly, we observed regulating effects of PRGXP on the tumor.
Results:
-
According to the dosage of the PRGXP, three groups can be divided: the big, the middle and the small. The weight of tumor in the three groups separately are (0.926±0.237)g, (0.776±0.122)g and (0.935±0.227)g, which lower than the model group, corresponding to the antitumor rate are 24.6%, 36.8% and 23.9%.
-
The TI and SI of the three groups are higher than the model group. The TI of the middle group is (53.4±15.6)mg/10g, the percentage increase is 31.4% than the model group. The SI of the middle group is (65.0±10.1)mg/10g. The percentage increase is 45.1% than the model group.
-
The density of the TNF-α in three group are higher than the model group, out of which, the TNF-α density of the middle group is (85.97±19.41)pg·ml⁻¹. The middle group has statistic significance in compare with the model group (p<0.05). The density of the TNF-α in the FufangBanmao capsule (BM) group is (51.34±9.78)pg·ml⁻¹. The middle group has statistic significance in compare with the model group (p<0.05). The PRGXP middle group has statistic significance in compare with the BM group (p<0.05).
-
The density of IFN-γ in the two groups is higher than the model group, out of which, the IFN-γ density of the middle group is (90.85±11.91)pg·ml⁻¹. The middle group has statistic significance in compare with the model group (p<0.05). The density of the IFN-γ in the FufangBanmao capsule (BM) group is (66.73±11.76)pg·ml⁻¹. The PRGXP group also has statistic significance in compare with the Fu

fangBanmao capsule(BM) group (p<0.05).
conclusion: Peishiruanganxiaopiwan (PRGXP) can control tumor growth, increase the weight of thymus and spleen in H22 Tumor—bearing Mice, enhance the secretion of TNF—α and IFN—γ, boost up the activity of cells and improve the immunologic function of the body. All of these can play the roles of antitumor.

前言
原发性肝癌(primary hepatocellular carcinoma,PHC),简称肝癌,是常见的恶性肿瘤之一,在恶性肿瘤死亡中仅次于胃癌和食管癌[1],在我国高居第三位,常见于中年男性。因其恶性度高、病情进展快、病情隐匿,早期一般不易被发现,大部分肝癌患者就医时已发展到中、晚期,已不适合手术切除,即使适合手术的患者,两年复发率亦高达50%[2]。晚期肝癌尚无标准治疗方案,预后差,因此需寻找更加有效的治疗方法。目前原发性肝癌被《中国癌症预防与控制规划纲要》列为我国癌症防治重点疾病之一[3]。
目前对肝癌的治疗,早期以手术切除为主,并辅以放、化疗。但从现有的资料来看:手术根治率不高,且术后复发率高;加之肝癌对放、化疗不敏感,且易转移,大多数患者发现时已属晚期,已失去手术意义。医学界在寻求和使用抗癌药物的同时,发现其毒副作用大,即:许多化学抗癌药物在作用于靶细胞时往往累及正常细胞,且有不同程度的致突变遗传毒性,为此治疗肿瘤的同时又增加了病人患第二种肿瘤的可能性;植物药的遗传毒性似乎不太明显[4-5]。中医药具有改善临床症状、提高生存质量、延长生存期等方面的独特优势,故寻找临床有效的肝癌综合治疗方案是延长肝癌患者生存时间及改善生存质量的重要手段,具有十分重要的现实意义。
原发性肝癌属于祖国医学中肝积、肥气、积聚、鼓胀等范畴,对于其病因病机的认识为:正虚致病。亦《素问·刺法论》曰:"正气存内,邪不可干,邪之所凑,其气必虚"、《医宗必读》曰:"积之成也,正气不足,而后邪气踞也"。故中医理论认为,正气亏虚是导致癌症的主要病因,故而张元素说:"盖壮人无积,惟虚人则有之"。
裴氏软肝消痞丸是全国著名中西医结合专家裴正学教授四十年来治疗原发性肝癌、胃癌的专方,在临床上疗效显著。曾经完全根治了多例原发性肝癌、胃癌,对大多数不适合手术患者均有不同程度的临床疗效。裴老认为原发性肝癌是由正气亏虚,脏腑功能失调,气滞、血瘀、痰凝等结聚而成。本病本虚标实、正虚邪实。导师总结:恶性肿瘤发生、发展的根本原因为"正虚"、治疗恶性肿瘤的基本法则为扶正固本,由此提出"扶正以消积,消积而固本",进而拟定了"肝癌方",经临床不断实践、充实、重组,最后锤炼为"裴氏软肝消痞丸"(由柴胡、生鳖甲、穿山甲、皂角刺、枳实、白花蛇舌草、半枝莲、三棱、莪术、白芍、海藻、昆布、丹参、黄芪等组成)。多年
