ABSTRACT
Objective To observe the clinical efficacy of modified Yiqi Shengjiang Decoction for chronic heart failure (CHF) and its effects on BNP and LP-PLA2. Methods Totally 100 cases of patients with CHF were randomly divided into treatment group and control group, with 50 cases in each group. The control group received basic treatment, and the treatment group was treated with modified Yiqi Shengjiang Decoction on the basis of control group, one dosage per day, twice a day, orally, for 4 weeks. The curative effect of heart function grading and curative effect of TCM symptoms of the two groups, the changes of plasma BNP and LP-PLA2 levels were observed. Safety indicators were monitored. Results The total effective rate of cardiac function classification was 88％ (44/50) in the treatment group and 68％ (34/50) in the control group, with the treatment group much better than the control group (P<0.05); the total effective rate of TCM symptom efficacy was 90％ (45/50) in the treatment group and 74％ (37/50) in the control group, with the treatment group much better than the control group (P<0.05). The BNP and LP-PLA2 levels in the treatment group were lower than the control group after treatment, with statistical significance (P<0.05). No adverse reactions were observed in both groups, with no abnormalities in blood, urine, liver and kidney function. Conclusion Modified Yiqi Shengjiang Decoction combined with Western medicine has obvious advantages in the treatment of CHF in improving patients' heart function, and reducing plasma BNP and LP-PLA2 levels.
ABSTRACT
The study of mammary gland bioreactor is in the ascendant. In order to generate transgenic goats of well-controlled expression of exogenic genes, we constructed a human lactoferrin (hLF) gene targeting vector containing promoter, exon 1, intron1 and some of exon 2 (about 6.1 kb fragment) and exon 6 approximately 9 (about 3.3 kb fragment) of the goat beta-casein gene as well as hLF minigene, neo gene inserted into them and tk gene ligated to the 3' end of the construct. The 9.4 kb goat genomic sequences as homologous arms were initially amplified by PCR with local goat tissue DNA. The expression vector was named pBC-tk-neo-hlf. Then the recombinant plasmid pBC-tk-neo-hlf containing hLF minigene was transfected into mice mammary tumor cell line C127 by liposome, cell clones were selected with G418. After proliferating, the transfected cells were induced with insulin, luteotropic hormone and hydrocortisone. The result of Western-blotting analysis showed that the transfected cells can secrete hLF protein, and the recombinant protein expressed in cultured cell supernatant has the similar molecular weight as the native protein. The expression level detected by ELISA was 0.21 microg/mL. This result indicated that the targeting vector could efficiently direct the expression of hLF in mammary cells,and it confirmed the validity of the constructed vector. At the same time, C127 cell line proved to be useful for evaluating the regulation of a foreign gene expression in mammary gland specific expression vector.

Objective:To evaluate the efficacy and safety of itraconazole in the treatment of fungal infection in the patients with hematological malignancies.Method:53 patients with malignant hematologic diseases were divided into three groups:empirical treatment group, suspected fungal infection group and established group.Itraconazole was given in a dose of 200mg twice daily in the first and the second days, from the third day in a dose of 200mg once daily.Response was established as normalization of temperature in the patients receiving itraconazole, and disappearance of clinical signs in the patients with suspected or established infection.Result:The 31 patients were eligible for efficacy evaluation for empirical treatment,and 25 responded to itraconazole(80.65%);of 9 established patients,6 responded to itraconazole(66.67%);of 13 suspected infection patients, 10 responded to itraconazole(76.92%).As to the side effects, there were no rigor and fever, but hepatotoxiciy were present in 5.66%, and no nephrotoxicity.Conclusion:Itraconazole is a highly effective drug with low side effects in treatment of fungal infections.But the hepatic and renal function tests must be carried out regularly when itraconazole infection is used.
