ABSTRACT
Objective To explore the research of Jianpi-Huatan decoction resisting the nude mouse MFC hepatic metastasis and its mechanism. Methods MFC cells inoculation in nude mice spleen, establishing nude mice hepatic metastasis model, which are divided into model group, 5-fu injection group, Jianpi-Huatan decoction high, medium and low dose group according to radom number table. Mice in high, medium and low dose Jianpi-Huatan decoction groups were adiminstrated with 80,40 and 20 g/kg Jianpi-Huatan decoction,in 5-fu groups were adiminstrated by intraperitoneal injection with 60mg/kg 5-fu injection and in model groups with Physiological saline once a day for 4 consecutive weeks. After the end, calculate the nude mice weight, spleen tumor weight and evaluation of hepatic metastases. And immune histochemical method and RT-PCR method is applied to detect tumor tissue of the expression of P53, Bcl-2 protein and mRNA. Results Compared with model group, Jianpi-Huatan decoction high and medium dose group can obviously increase body weight[(21.40 ± 1.43)g, (21.70 ± 1.02)g vs.(20.37 ± 1.17)g] and reduce the in situ tumor weight [(0.26 ±0.13)g,(0.16 ±0.05)g vs.(0.63 ±0.17)g]and the number of liver metastases;the mRNA levels of P53 and Bcl-2 (8.32 ±0.38,5.42 ±0.45,3.09 ±0.26 vs.9.67 ±1.31)and(4.65 ±0.61,3.22 ±0.21,2.49 ±0.19 vs.5.32 ±0.42) were decreased in low,medium and high dose Jianpi-Huatan decoction groups;P53(76.11 ±5.23,45.20 ±3.77, 23.11 ± 3.14 vs.81.63 ± 5.01)and Bcl-2(58.67 ± 5.27,32.00 ± 3.13,19.00 ± 2.54 vs.63.00 ± 4.10)levels were down-regulated in each dose of Jianpi-Huatan decoction group.Conclusions Jianpi-Huatan decoction can restrain nude mouse transplantation tumor growth and hepatic metastasis, which related to the cut of the expression of P53, Bcl-2 gene and protein.
ABSTRACT
OBJECTIVE: To study the effect of Jianpi Huoxue Jiedu (JPHXJD) prescription on prevention of the postoperative metastasis of gastric cancer and to observe the changes of immunity and whole blood viscosity after treatment. METHODS: JPHXJD prescription and chemotherapy were administered to the treated group for 12 successive months, while only chemotherapy was given to the control group. RESULTS: The effective rate of anti-metastasis in the treated group was obviously better than that in the control group. In the aspects of enhancing Karnofsky scores, reducing whole blood viscosity and improving immunity after treatment, the treated group was better than the control group (P<0.05). CONCLUSION: JPHXJD prescription combined with chemotherapy shows apparent effect on anti-metastasis. It can improve the quality of life of the patients, lower the whole blood viscosity and improve the immunity function.
ABSTRACT
Serum concentrations of endogenous digoxin-like substance (EDLS) and prolactin (PRL) in 34 patients with acute craniocerearal in jules (ACI) were determined by radioimmunoassay. The result showed that serum EDLS and PRL in these patients were significantly higher than those in controt group (p
ABSTRACT
We measured Plasma endothelin 1 (ET-1) concentrations in 110 normal pregnant women (NPW) and 23 normal non pregnant women (NNPW), that of maternal venous (MV), umbilical artery (UA) and umbilical vein (UV) in 20 normal parturient women at term (vaginal), and the tissue ET-1 concentrations of the placenta, fetal membrane, decidua and myometrium in 12 normotensive women at term (caesarean section) by radioimmunoassay. Results: compared with NNPW, plasma ET-1 levels were significantly decreased in NPW, and the lowest levels was in the second trimester. The plasma ET-1 levels were significantly increased in the labour, and were similar to that in NNPW. There were significant positive correlations between plasma ET-1 levels and mean arterial pressure in NNPW and NPW during the first, second and third trimester. UA and UV (ET -1) were 3.7 and 6.5 times of MV (ET 1), the UV (ET 1) was higher than UA (EF-1) significantly. The ET-1 concentrations of fetal membrane, placenta, decidua and myometrium were 38, 26, 19 and 11 times of MV (ET 1). Conclusions: ET 1 may play an important role in the initiation and process of labour and the regulation of blood pressure.
