[Ginger-partitioned moxibustion in the prevention of nausea and vomiting induced by chemotherapy in lung cancer：a randomized controlled trial].

OBJECTIVE: To observe the effect of ginger-partitioned moxibustion intervention on gastrointestinal reaction, the quality of life, the counts of blood platelet (PLT) and white blood cells (WBC) after chemotherapy in lung cancer patients. METHODS: The lung cancer patients treated with chemotherapy were randomized into observation group (30 cases) and control group (30 cases). In the control group, the intravenous injection with Tropisetron(5 mg) was given 1 h before chemotherapy. In the observation group, in addition to the same treatment as the control group, 2 hours after chemotherapy, ginger-partitioned moxibustion was applied to bilateral Zusanli (ST36), bilateral Neiguan (PC6) and bilateral Tianshu (ST25) for 20 min each time. The treatments were conducted once daily for 3 days. Separately, 2 days before chemotherapy, 24 h and 7 days after chemotherapy, the gastrointestinal reaction score and the score of the quality of life, the PLT and WBC counts were observed in the two groups. RESULTS: The effective rate of the gastrointestinal reaction degree in the observation group were higher than those in the control group 24 h and 7 days after chemotherapy (P<0.05). Twenty-four hours after chemotherapy, the score of the quality of life, the PLT and WBC counts were lower as compared with those before the treatment in both groups respectively(P<0.05). Seven days after chemotherapy, the score of the quality of life, the PLT and WBC counts in the observation group were higher than those in the control group (P<0.05). CONCLUSION: The ginger-partitioned moxibustion achieves the definite clinical effect of the prevention of nausea and vomiting induced by chemotherapy in lung cancer. This therapy is simple in operation, high in safety, absent in obvious adverse reactions and high in patient's compliance.

[Ginger-partitioned moxibustion in prevention of vomiting induced by chemotherapy in advanced malignant bone tumors: a randomized controlled trial].

OBJECTIVE: To observe the effect of ginger-partitioned moxibustion on digestive tract reaction, quality of life and white blood cell count after chemotherapy in advanced malignant bone tumors patients. METHODS: A total of 64 patients were randomly divided into an observation group and a control group, 32 cases in each group. Both groups were treated with adriamycin combined with cisplatin (AP) chemotherapy. The patients in the control group were treated by tropisetron hydrochloride intravenous on preventing the vomiting 1 h before receiving chemotherapy. On the basis of the control group, the patients in the observation group were treated with ginger-partitioned moxibustion at Neiguan (PC 6), Zusanli (ST 36), Shenque (CV 8), and Zhongwan (CV 12) 2 h after chemotherapy, once a day, 30 min each time. The course of chemotherapy, ginger-partitioned moxibustion and tropisetron hydrochloride intravenous was 5 days. The digestive tract reaction rating, quality of life score and white blood cell count were compared 1 d before chemotherapy, 2 d after chemotherapy and 7 d after chemotherapy between the two groups. RESULTS: The number of 0 grade in digestive tract reaction 2 d and 7 d after chemotherapy in the observation group was significantly higher than that in the control group (P<0.05), and the number of Ⅲ、Ⅳ grade was lower than that in the control group (P<0.05). The quality of life scores of both groups 2 d after chemotherapy were lower than those before chemotherapy (P<0.05), and there was no significant difference between the two groups (P>0.05). The quality of life score of the control group 7 d after chemotherapy was lower than that before chemotherapy (P<0.05), the quality of life score of the observation group was not statistically different from that before chemotherapy (P>0.05), and the quality of life score in the observation group was higher than that in the control group (P<0.05). The white blood cell count 2 d after chemotherapy in both groups was lower than before treatment (P<0.05), and there was no significant difference between the two groups (P>0.05). Seven days after chemotherapy, the white blood cell count in the control group was lower than that before chemotherapy (P<0.05), while there was no significant difference in the observation group compared with before chemotherapy (P>0.05), and the white blood cell count in the observation group was higher than that in the control group (P<0.05). CONCLUSION: Ginger-partitioned moxibustion can prevent and treat vomiting after chemotherapy in advanced malignant bone tumors, and improve the quality of life and white blood cell count of patients.

[Effect of Jinlongshe Granule Drug-containing Serum on Tube Formation, Migration and Apoptosis of Human Lymphatic Endothelial Cells in vitro].

Objective To observe the inhibitory effect of Jinlongshe Granule drug-containing serum (JG-DS) on tube formation, migration, and apoptosis of human lymphatic endothelial cells ( HLECs) in vitro. Methods JG-DS was prepared. The 3rd-passage HLECs were divided into the control group (cultured with normal saline containing serum) and the experimental group (cultured with JG-DS). After cultured for 12 h, the tube formation ability was detected by Matrigel assay, and the migration ability was determined by Transwell assay in the two groups. Cell apoptosis rate was detected by flow cytometry and Annexin-V-FITC/Pl staining method. Results The total length of tube was (3 084. 49 ?326. 27) p.m after acted by 10% JG-DS for 12 h, significantly shorter than that of the control group (7 058.93 ?4 567. 39) pm (P <0.01). The migration number of HLECs was (99 ?26), obviously lower than that of the control group (160 ?32; P <0.05). The apoptosis rate of the two groups was not statistically significant (P >0.05). Conclusion JG could inhibit the tube formation and migration of HLECs in vitro, which might be one of mechanisms for inhibiting tumor micro-lymphatics.

Xiaotan Sanjie decoction attenuates tumor angiogenesis by manipulating Notch-1-regulated proliferation of gastric cancer stem-like cells.

AIM: To determine the underlying mechanisms of action and influence of Xiaotan Sanjie (XTSJ) decoction on gastric cancer stem-like cells (GCSCs). METHODS: The gastric cancer cell line MKN-45 line was selected and sorted by FACS using the cancer stem cell marker CD44; the stemness of these cells was checked in our previous study. In an in vitro study, the expression of Notch-1, Hes1, Vascular endothelial growth factor (VEGF), and Ki-67 in both CD44-positive gastric cancer stem-like cells (GCSCs) and CD44-negative cells was measured by Western blot. The effect of XTSJ serum on cell viability and on the above markers was measured by MTT assay and Western blot, respectively. In an in vivo study, the ability to induce angiogenesis and maintenance of GCSCs in CD44-positive-MKN-45- and CD44-negative-engrafted mice were detected by immunohistochemical staining using markers for CD34 and CD44, respectively. The role of XTSJ decoction in regulating the expression of Notch-1, Hes1, VEGF and Ki-67 was measured by Western blot and real-time polymerase chain reaction. RESULTS: CD44(+) GCSCs showed more cell proliferation and VEGF secretion than CD44-negative cells in vitro, which were accompanied by the high expression of Notch-1 and Hes1 and positively associated with tumor growth (GCSCs vs CD44-negative cells, 2.72 ± 0.25 vs 1.46 ± 0.16, P < 0.05) and microvessel density (MVD) (GCSCs vs CD44-negative cells, 8.15 ± 0.42 vs 3.83 ± 0.49, P < 0.001) in vivo. XTSJ decoction inhibited the viability of both cell types in a dose-dependent manner in vitro. Specifically, a significant difference in the medium- (82.87% ± 6.53%) and high-dose XTSJ groups (77.43% ± 7.34%) was detected at 24 h in the CD44(+) GCSCs group compared with the saline group (95.42% ± 5.76%) and the low-dose XTSJ group (90.74% ± 6.57%) (P < 0.05). However, the efficacy of XTSJ decoction was reduced in the CD44(-) groups; significant differences were only detected in the high-dose XTSJ group at 48 h (78.57% ± 6.94%) and 72 h (72.12% ± 7.68%) when compared with the other CD44- groups (P < 0.05). Notably, these differences were highly consistent with the Notch-1, Hes1, VEGF and Ki-67 expression in these cells. Similarly, in vivo, XTSJ decoction inhibited tumor growth in a dose-dependent manner. A significant difference was observed in the medium- (1.76 ± 0.15) and high-dose XTSJ (1.33 ± 0.081) groups compared with the GCSCs control group (2.72 ± 0.25) and the low-dose XTSJ group (2.51 ± 0.25) (P < 0.05). We also detected a remarkable decrease of MVD in the medium- (7.10 ± 0.60) and high-dose XTSJ (5.99 ± 0.47) groups compared with the GCSC control group (8.15 ± 0.42) and the low-dose XTSJ group (8.14 ± 0.46) (P < 0.05). Additionally, CD44 expression was decreased in these groups [medium- (4.43 ± 0.45) and high-dose XTSJ groups (3.56 ± 0.31) vs the GCSC control (5.96 ± 0.46) and low dose XTSJ groups (5.91 ± 0.38)] (P < 0.05). The significant differences in Notch-1, Hes1, VEGF and Ki-67 expression highly mirrored the results of XTSJ decoction in inhibiting tumor growth, MVD and CD44 expression. CONCLUSION: Notch-1 may play an important role in regulating the proliferation of GCSCs; XTSJ decoction could attenuate tumor angiogenesis, at least partially, by inhibiting Notch-1.

Xiaotan Tongfu granules contribute to the prevention of stress ulcers.

AIM: To investigate the efficacy and potential mechanism of Xiaotan Tongfu granules (XTTF) in stress ulcers. METHODS: One hundred sixty rats were randomly divided into 4 groups (n = 10) as follows: the model group (MP group), the control group (CP group), the ranitidine group (RP group) and the XTTF granule group (XP group). Rats in the MP group received no drugs, rats in the CP group received 0.2 mL of a 0.9% sodium chloride solution via oral gavage, and rats in the RP and XP groups received the same volume of ranitidine (50 mg/kg) or XTTF granule (4.9 g/kg). The cold-restraint stress model was applied to induce stress ulcers after 7 consecutive days of drug administration. Afterwards, rats were sacrificed at 0, 3, 6 and 24 h. Gastric pH was measured by a precise pH meter; gastric emptying rate (GER) was measured by using a methylcellulose test meal; myeloperoxidase activity (MPO), macrophage migration inhibitory factor (MIF), proliferating cell nuclear antigen (PCNA), and heat shock protein 70 (HSP70) were measured by immunohistochemical staining; and mucosal cell apoptosis was measured by transferase dUTP nick end labeling. RESULTS: In the cold-restraint stress model, the development of stress ulcers peaked at 3 h and basically regressed after 24 h. Gastric lesions were significantly different in the RP and XP groups at each time point. Interestingly, although this index was much lower in the RP group than in the XP group immediately following stress induction (7.00 ± 1.10 vs 10.00 ± 1.79, P < 0.05. Concerning gastric pH, between the RP and XP groups, we detected a statistically significant difference immediately after stress induction (0 h: 4.56 ± 0.47 vs 3.34 ± 0.28, P < 0.05) but not at any of the subsequent time points. For GER, compared to the RP group, GER was remarkably elevated in the XP group because a statistically significant difference was detected (3 h: 46.84 ± 2.70 vs 61.16 ± 5.12, P < 0.05; 6 h: 60.96 ± 6.71 vs 73.41 ± 6.16, P < 0.05; 24 h: 77.47 ± 3.17 vs 91.31 ± 4.34, P < 0.05). With respect to MPO and MIF, comparisons between the RP and XP groups revealed statistically significant differences at 3 h (MPO: 18.94 ± 1.20 vs 13.51 ± 0.89, P < 0.05; MIF: 150.67 ± 9.85 vs 122.17 ± 5.67, P < 0.05) and 6 h (MPO: 13.22 ± 1.54 vs 8.83 ± 0.65, P < 0.05; MIF: 135.50 ± 9.46 vs 109.83 ± 6.40, P < 0.05). With regard to HSP70, HSP70 expression was significantly increased in the RP and XP groups at 3 and 6 h compared to the MP and CP groups. In addition, comparing the RP and XP groups also showed statistically significant differences at 3 and 6 h. The expression of PCNA was higher in the RP and XP groups 3 h after stress induction. Between these two groups, small but statistically significant differences were observed at all of the time points (3 h: 69.50 ± 21.52 vs 79.33 ± 15.68, P < 0.05; 6 h: 107.83 ± 4.40 vs 121.33 ± 5.71, P < 0.05; 24 h: 125.33 ± 5.65 vs 128.50 ± 14.49, P < 0.05) except 0 h. With regard to apoptosis, the apoptotic activity in the RP and XP groups was significantly different from that in the MP and CP groups. The XP group exhibited a higher inhibition of cell apoptosis than the RP group at 3 h (232.58 ± 24.51 vs 174.46 ± 10.35, P < 0.05) and 6 h (164.74 ± 18.31 vs 117.71 ± 12.08, P < 0.05). CONCLUSION: The Xiaotan Tongfu granule was demonstrated to be similar to ranitidine in preventing stress ulcers. It exhibited multiple underlying mechanisms and deserves further study.
