RESUMEN

OBJECTIVES: To explore the potential molecular mechanism underlying the effect of green tea extract (TE), rich in tea polyphenols (TPs), on improving alcohol-induced liver injury. METHODS: Mice were intragastrically treated with 50% (v/v) alcohol administration (15 ml/kg BW) with or without three doses of TE (50, 120 and 300 mg TPs/kg BW) daily for 4 weeks, and biological changes were tested. KEY FINDINGS: The TE improved the functional and histological situations in the liver of the mice accepted alcohol administration, including enzymes for alcohol metabolism, oxidative stress and lipid accumulation. Interestingly, the TE increased the nuclear translocation of nuclear factor erythroid-2-related factor 2 (Nrf2), with the decreasing expression of kelch-like ECH-associated protein 1 (Keap1), indicating the association between the effect of TE with Nrf2-mediated antioxidant signalling. Moreover, the TE restored the activity of autophagy, showing as lifted Beclin-1 expression, LC3B-II/LC3B-I ratio, and decreased p62 expression. Importantly, all these effects were dose-dependent. CONCLUSIONS: These findings provide a new notion for the first time that the TE preventing against alcohol-induced liver injury is closely related to accelerated metabolism of alcohol and relieved oxidative stress, which is associated with Nrf2 signalling activation and autophagy restoration, thus the reduction of lipid accumulation in liver.

RESUMEN

This study was carried out to study the effects of selenylation on physicochemical and biological properties of polysaccharide (SPP) extracted from Sargassum pallidum. The selenized derivative of SPP (Se-SPP) with the selenium content of 2419 µg/g was synthesized by sodium selenite/dilute nitric acid method. Physicochemical characterization indicated that selenylation modification resulted in some changes in chemical composition, monosaccharide composition, molecular weight and surface morphology of polysaccharides. FT-IR spectroscopy showed that a new absorption peak appeared at 675 cm-1 in Se-SPP probably due to the substitution of selenyl groups. Bioactivity assay showed that Se-SPP exhibited higher scavenging radical activities and ferrous ion chelating activities than native SPP. Compared with SPP and acarbose, Se-SPP showed more significantly inhibitory effect on α-glucosidase activity in a noncompetitive inhibition type. The IC50 values of SPP, Se-SPP and acarbose were determined as 1.579, 0.896 and 2.742 mg/mL, respectively. These results suggest that Se-SPP can be used to develop a new selenium-complementary ingredient in functional foods.

RESUMEN

OBJECTIVE: To observe effect of acupuncture combined with hypothermia therapy on MAPK/ERK pathway and apoptosis related factorsin rats suffered cerebral ischemia reperfusion and to explore underlying mechanisms.
 Methods: Middle cerebral artery ischemia model were established.Ninety SD rats were randomly assigned into a blank group, a control group, a model group, an acupuncture group, a mild hypothermia group, and an acupuncture with hypothermia group. After 72 h treatment, nerve function defect scores were observed, and infarction area percent was detected by 2, 3, 5-triphenyl-2H-tetrazolium chloride (TTC) staining; expressions of Bcl-2 and Bax were examined by immunohistochemistry; apoptotic cells were detected by TUNEL assay; and expression levels of phospho-mitogen-activated protein kinase(p-MEK2) and phospho-extracellular signal regulated kinase 1/2 (p-ERK1/2) in the rats' hippocampus ischemic side were determined by Western blot.
 Results: In the rats of the model group, the neural function defect scores, the infarction area percent, the expression level of Bax, and apoptotic cells increased, while the level of Bcl-2 decreased significantly. The level of p-MEK2 and p-ERK1/2 increased obviously compared with the blank and control groups (P<0.05 or P<0.01). After treatment with acupuncture and hypothermia, the neural function defect scores, infarction area percent, and the level of Bax, apoptotic cells and the levels of p-MEK2 and p-ERK1/2 were significantly decreased, while the level of Bcl-2 in the treatment group was significantly elevated (P<0.05 or P<0.01) compared with the model group. Compared with the acupuncture group or the hypothermia group, the neural function defect scores and the levels of p-MEK2 and p-ERK1/2 in the acupuncture combined with hypothermia group were significantly reduced (P<0.05 or P<0.01).
 Conclusion: Acupuncture and hypothermia therapy can improve cerebral function, and reduce the cerebral injury through down-regulation of Bax level, and up-regulation of Bcl-2 level, which is related to reducing the levels of p-MEK2 and p-ERK1/2. The therapeutic effects on cerebral ischemia reperfusion injury for combination of acupuncture with hypothermia are better than those with single application of acupuncture or hypothermia.

RESUMEN

In order to investigate the content and distribution of available element in the rhizonsphere soil of the growing areas of Salvia miltiorrhiza Bunge, the contents of available element (N,P,K,B,Cu,Zn,Fe,Mn) in 26 soil samples were tested and evaluated. The results showed that the contents of available P and Fe were very plentiful, available K, Cu and Zn were rich, available N and Mn were deficient, available B was extremely deficient in all growing areas of S. miltiorrhiza of eight provinces in China. The correlation analysis showed that the contents of eight kinds of available elements were varying degree correlation. The stepwise regression analysis between the contents of available elements of rhizonsphere soil and ten kinds of active ingredients of Danshen (Salviae Miltiorrhizae Radix et Rhizoma) were researched. The results showed that the rates of contribution of available N,B,Mn and Fe to quality of Danshen were relatively large and they were the significant factors, and the other factors did not show statistical significance. The recommended fertilizing strategies is that the usage of N,B and Mn fertilizers should be controlled according to different stages of growth of S. miltiorrhiza, and P fertilizer should be reduced in all growing areas of S. miltiorrhiza.

RESUMEN

To prepare ginsenoside-Rh2 lipid nanoparticles, and investigate the synergistic effect with borneol in resisting tumor activity in vitro. Ginsenoside-Rh2 lipid nanoparticles were prepared by ultrasonic-assisted solvent evaporation method, and orthogonal design was adopted to optimize formulation process. Its encapsulation efficiency, drug loading ratio, particle size distribution, Zeta potential, morphology and in vitro drug release behavior were characterized, and synergistic effect with borneol in resisting tumor activity were preliminarily studied by MTT. These nanoemulsion particles prepared by the optimized process method were rounding and even in a good shape. Encapsulation efficiency and drug loading ratio of three batches of nanoemulsion particles were (77.3±2.5)% and (7.2±0.2)%, respectively. Nanoemulsion particles showed an obvious sustained release characteristics, with 52.42% cumulative release within 96 h. The killing effect of nanoemulsion particles on glioma cells was dose-dependent, with IC50 of 22.33 µmol•L⁻¹ and 11.46 µmol•L⁻¹ after 24 h and 48 h, respectively. After the combination with borneol, the killing effect of nanoemulsion particles on glioma cells was dose-dependent, with IC50 of 16.36 µmol•L⁻¹ and 8.04 µmol•L⁻¹ after 24 h and 48 h, respectively.

RESUMEN

In this study, one immortalized human normal prostatic epithelial cell line (BPH) and four human prostate cancer cell lines (LNCaP, 22Rv1, PC-3, and DU-145) were treated with Ganoderma Lucidum triterpenoids (GLT) at different doses and for different time periods. Cell viability, apoptosis, and cell cycle were analyzed using flow cytometry and chemical assays. Gene expression and binding to DNA were assessed using real-time PCR and Western blotting. It was found that GLT dose-dependently inhibited prostate cancer cell growth through induction of apoptosis and cell cycle arrest at G1 phase. GLT-induced apoptosis was due to activation of Caspases-9 and -3 and turning on the downstream apoptotic events. GLT-induced cell cycle arrest (mainly G1 arrest) was due to up-regulation of p21 expression at the early time and down-regulation of cyclin-dependent kinase 4 (CDK4) and E2F1 expression at the late time. These findings demonstrate that GLT suppresses prostate cancer cell growth by inducing growth arrest and apoptosis, which might suggest that GLT or Ganoderma Lucidum could be used as a potential therapeutic drug for prostate cancer.

RESUMEN

Oxidative stress is implicated in male infertility and significantly higher reactive oxygen species are detected in 25% of infertile males. Although different agents of various alternative medicines, including traditional Chinese medicine, have been tried with varying success, evidence remains limited on whether and how much herbs or supplements might help increase the anti-oxidant ability of the sperm. This study examined the anti-oxidative effects of icariin, a flavonoid isolated from Herba Epimedii, on the human sperm. We prepared the FeSO4/H2O2-damaged human sperms, which were co-cultured with icariin in vitro, and then observed the changes of the sperm by employing Raman micro-spectroscopy. The results showed that Raman mapping with a 514 nm excitation laser allowed clear differentiation of the nucleus, neck, and, in particular, the mitochondria-rich middle piece of a human sperm cell. The effect of icariin on different organelles of the sperm was quantified by localized spectral Raman signatures obtained within milli-seconds, and icariin could keep the "Raman fingerprint" of the human sperm the same as the control groups, suggesting that icariin could protect the human sperm from being damaged by FeSO4/H2O2. Icariin may serve as a tonifying and replenishing agent of herbal origin for enhancing reproductive functions.

RESUMEN

BACKGROUND: Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) targeted treatment has been a standard therapy for advanced non-small cell lung cancer (NSCLC), but it is not tolerated well by all patients. In China, some studies have reported that traditional Chinese medicinal herbs (TCMHs) may increase efficacy and reduce toxicity when combined with EGFR-TKI, but outside of China few studies of this kind have been attempted. OBJECTIVE: This study is intended to systematically review the existing clinical evidence on TCMHs combined with EGFR-TKI for treatment of advanced NSCLC. SEARCH STRATEGY: PubMed, the Cochrane Library, the Excerpta Medica Database (EMBASE), the China BioMedical Literature (CBM), and the China National Knowledge Infrastructure (CNKI) and web site of the American Society of Clinical Oncology (ASCO), the European Society for Medical Oncology (ESMO), the World Conference of Lung Cancer (WCLC) were searched; the search included all documents published in English or Chinese before October 2013. INCLUSION CRITERIA: We selected randomized controlled trials based on specific criteria, the most important of which was that a TCMH plus EGFR-TKI treatment group was compared with an EGFR-TKI control group in patients with advanced NSCLC. DATA EXTRACTION AND ANALYSIS: The modified Jadad scale was used to assess the quality of studies. For each included study, patient characteristics, treatment details, therapeutic approach and clinical outcomes were collected on a standardized form. When disagreements on study inclusion or data extracted from a study emerged, the consensus of all coauthors provided the resolution. The clinical outcome metrics consisted of objective response rate (ORR; complete response + partial response divided by the total number of patients), disease control rate (DCR; complete response + partial response + no change divided by the total number of patients), survival rate, improved or stabilized Karnofsky performance status (KPS), and severe toxicity. RevMan 5.0 software was used for data syntheses and analyses. Risk ratio (RR) and 95% confidence interval (CI) were calculated; if the hypothesis of homogeneity was not rejected (P>0.1, I(2)<50%), the fixed-effect model was used to calculate the summary RR and the 95% CI. Otherwise, a random-effect model was used. RESULTS: In this review, 19 studies were included based on the selection criteria. Of them, 13 studies were of high quality and 6 studies were of low quality, according to the modified Jadad scale. When the TCMH plus EGFR-TKI treatment groups were compared with the EGFR-TKI control groups the meta-analysis demonstrated a statistically significant higher ORR (RR 1.34; 95% CI 1.15 to 1.57; P=0.000 2), DCR (RR 1.18; 95% CI 1.09 to 1.27; P<0.000 1), one-year survival rate (RR 1.21; 95% CI 1.01 to 1.44; P=0.04), 2-year survival rate (RR 1.91; 95% CI 1.26 to 2.89; P=0.002) and improved or stable KPS (RR 1.38; 95% CI 1.26 to 1.51; P<0.000 01). Severe toxicity for rash was decreased (RR 0.55; 95% CI 0.32 to 0.94; P=0.03), as were nausea and vomiting (RR 0.17; 95% CI 0.04 to 0.72; P=0.02) and diarrhea (RR 0.46; 95% CI 0.24 to 0.89; P=0.02). Sensitivity analysis indicated that findings of the meta-analysis were robust to study quality. In the funnel plot analysis, asymmetry was observed, and publication bias was indicated by Egger's test (P=0.03). CONCLUSION: TCMH intervention can increase efficacy and reduce toxicity when combined with EGFR-TKI for advanced NSCLC, although this result requires further verification by more well designed studies.

RESUMEN

OBJECTIVE: To observe effects of xuefu zhuyu Oral Liquid (XZOL) on the brain behavior and monoamine neurotransmitter 5-HT, and brain derived neurotrophic factor (BDNF) content on depression model rats. METHODS: Male SD rats were randomly divided into the control group, the model group, the XZOL group, and the Deanxit Tablet group, 12 in each group. The depressive rat model was established by chronic unpredictable mild stress method. XZOL was administered to rats in the XZOL group by gastro-gavage, while Deanxit Tablet was given to those in the Deanxit Tablet group by gastrogavage. The intervention lasted for two weeks. The behavioral changes were observed by sucrose water consumption test and open-field test. The 5-HT and BDNF contents were detected using ELISA. RESULTS: After chronic stress stimulus, experimental rats in the model group might have abnormal behavioral changes and lowered 5-HT content, showing statistical difference when compared with the control group (P <0.01). No obvious change in stimulated rats' behavior after intervention of XZOL and Deanxit Tablet. 5-HT content was not obviously reduced (P>0.05). Besides, XZOL was superior to Deanxit Tablet in increasing the 5-HT content (P<0.05). But the brain BDNF level of rats in the model group was not statistically different from that of rats in the model group (P >0.05), while the brain BDNF level of rats in the XZOL group and the Deanxit Tablet group was lower than that of rats in the model group (P <0.01). CONCLUSIONS: Stress can lead to behavioral changes and lowered 5-HT content of rats. The intervention of XZOL could fight against depression-induced behavioral changes and increase 5-HT content. But it did not significantly affect the brain BDNF level. We inferred that it might not effect through the BDNF pathway.

RESUMEN

OBJECTIVE: To observe the intervention of Qisheng Mixture (QM) on the chemotherapy induced myelosuppression in patients with colorectal cancer. METHODS: One hundred and twenty patients with colorectal cancer at Ruijin Hospital, Shanghai Jiaotong University School of Medicine were randomly assigned to the pure chemotherapy group (as the control group) and the QM + chemotherapy group (as the treatment group), 60 in each group. All patients received FOLFOX4 or XELOX regimen for totally 6 cycles. Patients in the treatment group took QM 150 mL at the end of chemotherapy, once in the morning and once in the evening for 7 successive days, totally 6 therapeutic courses. The total and average dosages of using granulocyte colony stimulating factor (G-CSF) were observed in all patients. The changes of white blood cell (WBC) counts were determined before chemotherapy and after the 6th chemotherapy. The hemoglobin (Hb), red blood cell (RBC), and platelet (PLT) counts were observed before chemotherapy, before the 4th chemotheray, and after the 6th chemotherapy. The clinical symptoms integrals (fatigue, liability to catch cold, aphthous stomatitis, pharyngalgia, pale complexion, poor appetite, vomiting, diarrhea, and so on) and the safety indicators (the functions of the liver and kidney, urine routines) were observed. The grading toxic and adverse reactions, KPS scoring, body weight, and the efficacy of the symptoms integrals were compared between the two groups. RESULTS: During the treatment period the total and average dosages of G-CSF used were larger in the control group than in the treatment group (P<0.01). After treatment the WBC count of the two groups were reduced with statistical difference (P<0.01). The WBC counts were higher in the treatment group than in the control group in the whole therapeutic process except the first chemotherapy (P<0.01, P<0.05). Compared with before treatment in the same group, RBC and PLT were reduced in the two groups before the 4th chemotherapy, RBC, Hb, and PLT were reduced after treatment (P<0.05, P<0.01). Better effects on body weight were obtained in the treatment group than in the control group with statistical difference (P<0.01). Compared with the control group, the clinical symptoms integrals such as fatigue, liability to catch cold, pharyngalgia, pale complexion, poor appetite, vomiting, and diarrhea were reduced (P<0.01). Compared with the control group, the toxic and adverse reactions were reduced in the treatment group before the 4th chemotherapy (P<0.01).

RESUMEN

<p><b>OBJECTIVE</b>To observe the intervention of Qisheng Mixture (QM) on the chemotherapy induced myelosuppression in patients with colorectal cancer.</p><p><b>METHODS</b>One hundred and twenty patients with colorectal cancer at Ruijin Hospital, Shanghai Jiaotong University School of Medicine were randomly assigned to the pure chemotherapy group (as the control group) and the QM + chemotherapy group (as the treatment group), 60 in each group. All patients received FOLFOX4 or XELOX regimen for totally 6 cycles. Patients in the treatment group took QM 150 mL at the end of chemotherapy, once in the morning and once in the evening for 7 successive days, totally 6 therapeutic courses. The total and average dosages of using granulocyte colony stimulating factor (G-CSF) were observed in all patients. The changes of white blood cell (WBC) counts were determined before chemotherapy and after the 6th chemotherapy. The hemoglobin (Hb), red blood cell (RBC), and platelet (PLT) counts were observed before chemotherapy, before the 4th chemotheray, and after the 6th chemotherapy. The clinical symptoms integrals (fatigue, liability to catch cold, aphthous stomatitis, pharyngalgia, pale complexion, poor appetite, vomiting, diarrhea, and so on) and the safety indicators (the functions of the liver and kidney, urine routines) were observed. The grading toxic and adverse reactions, KPS scoring, body weight, and the efficacy of the symptoms integrals were compared between the two groups.</p><p><b>RESULTS</b>During the treatment period the total and average dosages of G-CSF used were larger in the control group than in the treatment group (P<0.01). After treatment the WBC count of the two groups were reduced with statistical difference (P<0.01). The WBC counts were higher in the treatment group than in the control group in the whole therapeutic process except the first chemotherapy (P<0.01, P<0.05). Compared with before treatment in the same group, RBC and PLT were reduced in the two groups before the 4th chemotherapy, RBC, Hb, and PLT were reduced after treatment (P<0.05, P<0.01). Better effects on body weight were obtained in the treatment group than in the control group with statistical difference (P<0.01). Compared with the control group, the clinical symptoms integrals such as fatigue, liability to catch cold, pharyngalgia, pale complexion, poor appetite, vomiting, and diarrhea were reduced (P<0.01). Compared with the control group, the toxic and adverse reactions were reduced in the treatment group before the 4th chemotherapy (P<0.01).</p><p><b>CONCLUSIONS</b>QM could effectively intervene chemotherapy induced myelosuppression in patients with colorectal cancer. It was a safe Chinese medicine compound with lower toxicity.</p>

RESUMEN

OBJECTIVE: To observe the clinical therapeutic effects of Dishen Qufeng Decoction (DSQFD), a compound traditional Chinese herbal medicine, in treatment of allergic rhinitis. METHODS: Sixty cases of allergic rhinitis were selected and randomized into DSQFD group (30 cases) and cetirizine group (30 cases), and the patients were orally administered DSQFD and cetirizine respectively. The integrals of patients' symptoms, such as sneezing, nose running, nasal occlusion and nasal itching, signs in the nasal conchae and peripheral blood eosinophil (EOS) count were abserved count before and after treatment. RESULTS: DSQFD obviously improved the symptoms and signs of allergic rhinitis. The total response rate of DSQFD treatment was 83.3%, while that of the cetirizine treatment was 86.7%; the EOS counts in both groups were significantly decreased. These results showed statistical difference between the two groups. CONCLUSION: DSQFD is an effective preparation of traditional Chinese medicine for treating allergic rhinitis.

RESUMEN

OBJECTIVE: To investigate the correlation between entophytic fungal community, habitations and varieties of Ligusticum. METHOD: The solidified potato dextrose agar (PDA) of plates was applied for the isolation of the endophytic fungi, and the identification was completed by spot-planting method. RESULT: Fifty strains of the entophytic fungi were isolated from the rhizome of L. chuanxiong collected from 6 habitations. They were morphologically identified as belonging to 13 genera, 4 families, 3 orders and 1 class. CONCLUSION: There were some differences at quantity, species and distributing of the entophytic fungi in different habitats and varieties of Ligusticum, which was suggested that entophytic fungal community is related with specific habitat.

RESUMEN

AIM: To further investigate the relaxation mechanism of neferine (Nef), a bis-benzylisoquinoline alkaloid extracted (isolated) from the green seed embryo of Nelumbo nucifera Gaertn in China, on rabbit corpus cavernosum tissue in vitro. METHODS: The effects of Nef on the concentrations of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) in isolated and incubated rabbit corpus cavernosum tissue were recorded using 125I radioimmunoassay. RESULTS: The basal concentration of cAMP in corpus cavernosum tissue was 5.67 +/- 0.97 pmol/mg. Nef increased the cAMP concentration in a dose-dependent manner (P < 0.05), but this effect was not inhibited by an adenylate cyclase inhibitor (cis-N-[2-phenylcyclopentyl]azacyclotridec-1-en-2-amine, MDL-12, 330A) (P > 0.05). The accumulation of cAMP induced by prostaglandin E1 (PGE1, a stimulator of cAMP production) was also augmented by Nef in a dose-dependent manner (P < 0.05). The basal concentration of cGMP in corpus cavernosum tissue is 0.44 +/- 0.09 pmol/mg. Nef did not affect this concentration of cGMP, either in the presence or in the absence of a guanyl cyclase inhibitor (1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one, ODQ) (P > 0.05). Also, sodium nitroprusside (SNP, a stimulator of cGMP production)-induced cGMP production was not enhanced by Nef (P > 0.05). CONCLUSION: Nef, with its relaxation mechanism, can enhance the concentration of cAMP in rabbit corpus cavernosum tissue, probably by inhibiting phosphodiesterase activity.

RESUMEN

OBJECTIVE: To explore the effects of serum containing Yiqi Xiaoji Recipe (YQXJR), a compound traditional Chinese herbal medicine for benefiting qi and removing stagnation, on cell line NKN-28 of gastric cancer. METHODS: The experimental SD rats were taken as the provider of the animal serum, and the serum was inactivated before the experiment. The serum was divided into high-dose, medium-dose, low-dose and blank serum groups based on whether the rats were given YQXJR and administration dosage. The inhibition rate was regarded as the observational index. RESULTS: The four groups of serum all had inhibitory effect on the growth of NKN-28 cells depending on the drug concentration. And there were significant differences among the experimental groups. High-dose, medium-dose and low-dose concentrations of serum all could inhibit the growth of NKN-28 cells with positive relations with the concentration and function time. CONCLUSION: YQXJR serum can inhibit the growth of NKN-28 cells depending on the drug concentration and function time.

RESUMEN

OBJECTIVE: To study the relaxants effects of six extractions from Chinese Herbs (neferine, tetrandrine, kakonein, scutellarin, ginsenoside Rgl and ginsenoside Rb1) on the corpus cavernosum tissue of rabbit in vitro. METHODS: Isolated stripes of rabbit corpus cavernosum tissue were precontracted with 10(-5) mol/L phenylephrine (PE). Relaxation in response to cumulative doses of six extracts at (10(-8) - 10(-3)) mol/L was determined. RESULTS: On rabbit cavernosal muscle stripes precontracted with PE, neferine, tetrandrine, kakonein and scutellarin showed dose dependent relaxation. IC50 values were 4.60 x 10(-6), 3.73 x 10(-5), 8.03 x 10(-4) and 3.33 x 10(-3) mol/L, respectively. However, in the meantime, it was found that the relaxant effects of ginsenoside Rgl and ginsenoside Rbl less significant to stripes precontracted with PE. When the final concentration was 10(-3) mol/L, the relaxations were only (16.32 +/- 5.45)% and (11.21 +/- 3.10)%. CONCLUSION: Among the six extracts which showed relaxant effects to rabbit cavernosal muscle stripes precontracted with PE, neferine had greater functions than the other five extracts.

RESUMEN

OBJECTIVE: To study the effects of intraperitoneal chemotherapy (IPC) plus Shenmai Injection (SMI) in treating advanced colorectal cancer following radical resections. METHODS: Fifty-eight cases of colorectal cancer in stage B2 and C following radical resections were divided into two groups: SMI+IPC group (36 cases) and IPC group (22 cases). In the SMI+IPC group, IPC (5-fluorouracil combined with cisplatin) plus SMI was administered, while in the IPC group, only IPC was administered. Clinical symptoms, quality of life (Karnofsky score), white blood cell counts, natural killer cells and CD4/CD8 were observed, and disease-free survival (DFS) rate was also evaluated. RESULTS: The total short-term response rate was 83.33% in the SMI+IPC group, significantly higher than 63.64% in the IPC group (P<0.05). The data of clinical symptoms, quality of life, white blood cell counts, natural killer cells and CD4/CD8 in the SMI+IPC group were also significantly improved as compared with those in the IPC group (P<0.05 or P<0.01). In the SMI+IPC group, 1-, 3- and 5-year DFS rates were 91.7% (33/36), 77.8% (28/36) and 72.2% (26/36) respectively, and those in the IPC group were 90.9% (20/22), 72.7% (16/22) and 45.5% (10/22) respectively. The 5-year DFS rate was significantly improved in the SMI+IPC group as compared with that in the IPC group (P<0.05), while the 1-year and 3-year DFS rates had no significant difference between these two groups. CONCLUSION: IPC plus SMI is effective in treating post-operative patients with advanced colorectal cancer.
