RESUMEN
Objective To observe the clinical efficacy of Jiajian Yijing Decoction on improving clinical symptoms and pregnancy rate of patients with diminished ovarian reserve(DOR)and kidney deficiency and hepat-ic depression syndrome. Methods Patients with DOR and kidney deficiency and hepatic depression syndrome were randomly divided into traditional Chinese medicine group(n = 33)and western medicine group(n = 34). Patients in TCM group were treated with Jiajian Yijing Decoction and those in western medicine group with artificial periodic therapy(Progynova 2 mg/d+Dydrogesterone 20 mg/d).All cases were treated with 3 menstrual cycles.The improvement of clinical symptoms of DOR and kidney deficiency and hepatic depression syndrome and pregnancy rate were observed. Results The improvement of clinical symptoms of DOR and kidney deficiency and hepatic depression syndrome after treatment in TCM group was more obvious than that in western medicine group(P<0.05 or P < 0.01). The pregnancy rate after treatment in TCM group was higher than that in western medicine group, but it had no statistic difference(P>0.05).Conclusions Jiajian Yijing Decoction can obviously improve the clin-ical symptoms of patients with DOR and kidney deficiency and hepatic depression syndrome and increase the preg-nancy rate in infertile patients.It is worthy of clinical popularization.
RESUMEN
Objective: To investigate the inhibitory effect of macrophage foaming by Yinlan Tianzhi formula (YLTZ) and to explain its effects on lipid-induced inflammation and LXRα-ABCA1 signal pathway. Methods: The model of macrophage foaming was induced by incubating the RAW264.7 cells or BMMs with ox-LDL (50 mg·L-1). The serum containing YLTZ was prepared. The cells were divided into blank group, model group, and drug group. After drug intervention, MTT method was used to detect cell proliferation. The lipid accumulation in cells was observed by oil red O staining, and GPO-PAP method was used to determine the total cholesterol content in cells. Protein and mRNA levels were determined by Western blot and RT- qPCR. Results: Compared with control group, after YLTZ treatment, the lipid level was significantly decreased, and the level of mRNA and protein of LXRα and ABCA1 were significant increased. The expression of inflammatory factor COX2 and iNOS was significantly decreased. Conclusion: YLTZ inhibits macrophage foaming through enhancing LXRα-ABCA1 pathway and suppressing of inflammatory response.

AIM To study the effects of No.1 Weiyan Decoction (Codonopsis Radix,Paeoniae Radix alba,Taraxaci Herba,etc.) on hypoxia and hypoxic tolerance in gastric mucosal epithelial cells in rats with precancerous lesion of gastric cancer (PLGC).METHODS Forty rats were randomly divided into normal,model,Vitacoenzyme Tablets and No.1 Weiyan Decoction groups.Except for the normal group,the rats in the other groups were given with N-methyl-N'-nitro-N-nitrosoguanidine and Little Chengqi Decoction to establish a PLGC rat model.Ten weeks after the administration,the gastric mucosal epithelial microvascular ultrastructure was observed,the expressions of Hif1a mRNA,HIF-1 α protein and VEGF protein in gastric mucosal epithelium were detected.RESULTS Compared with the normal group,the number of microvasculatures in gastric mucosal epithelium was decreased;lumen was severely stenosed or expansive;inner wall was not smooth and had adhesion;vascular endothelial cells were swollen;the expression of Hif1α mRNA showed an increasing trend;the expressions of HIF-1α protein and VEGF protein were anomalous in the model group.Compared with the model group,the gastric mucosal vascular lesion of PLGC rats was improved,and the expressions of Hif1a mRNA,HIF-1α protein and VEGF protein were significantly decreased in the No.1 Weiyan Decoction group.CONCLUSION No.1 Weiyan Decoction can improve hypoxia and hypoxia tolerance,and induce angiogenesis in gastric mucosal epithelium in PLGC rats.
RESUMEN
OBJECTIVE:To observe the effects of aerosol inhalation of Chuankezhi injection on lung index and tissue morphol-ogy of trachea,lung and esophagus in guinea pigs. METHODS:40 guinea pigs were randomly divided into blank control group (normal saline),Chuankezhi high-dose,medium-dose and low dose (2.48,1.24 and 0.62 ml/kg) groups. Each treatment group was administrated by inhaling the atomized injection,once a day,20 ml/kg,for consecutive 2 weeks. The general situation of guin-ea pigs was observed 1 h after each time of medication;1 h after last medication,lung index of guinea pigs was detected,as well as the tissue morphology of left lung,right lung,trachea and esophagus by HE staining. RESULTS:Compared with normal control group,the general situation of guinea pigs were normal in Chuankezhi high-dose,medium-dose and low dose groups;there was no difference in lung index and all of them were about 0.653;tissue section staining showed that no abnormal lesion was found in these tissues. CONCLUSIONS:2 weeks of aerosol inhalation of Chuankezhi injection have no significant effect on lung index and the tissue morphology of trachea,lung and esophagus of guinea pigs.
RESUMEN
Objective To observe the morphology changes in articular cartilage of knee osteoarthritis ( KOA) model rats after intervention with Shudi Jisheng Zhuanggu Decoction (SJZD). Methods SD rats were randomized into 7 groups, namely blank control group, model group, Paracetamol group ( 0.270 g/kg) , Zhuangu Guanjie Pills group ( 1.08 g/kg) , and high-, middle- and low-dosage SJZD groups ( 27.450, 13.725, 6.863 g/kg, respectively). Rats were injected with papain solution into the right knee joint to build models of KOA before administration of drugs. Thickness of right knee joint was measured to evaluate the effect of SJZD on the swelling degree of knee joint. Histological changes of knee cartilage were evaluated by Mankin scoring method after the cartilage sections being stained with hematoxylin-eosin (HE). Results Swelling degree of knee joint and Mankin scores were significantly increased in the model group compared to the blank control group ( P<0.01). In comparison with the model group, the swelling degree of knee joint and Mankin scores of SJZD groups were significantly decreased (P<0.05 or P<0.01), and the pathological changes were relieved. Conclusion SJZD can ameliorate the pathological changes of knee articular cartilage in rats with KOA, so as to delay cartilage degeneration and protect the cartilage.
RESUMEN
This article focused on summarization of the available new screening technology for traditional Chinese medicine (TCM) new drug, including high throughput screening (HTS), biological chip, molecular biological chro-matography, high content screening (HCS), network pharmacology, proteomics, and computer-aided drug design (CADD). And in this review, one example that we applied CADD technology (such as molecular docking, pharma-cophore and molecular similarity) in lipid-lowering TCM new drug development was given. Based on the mechanism of lipid metabolism, CADD technology provided a good method on the prescription optimization and mechanism study. In addition, TCM new drug development proposal which displayed in this paper may provide a useful strategy for screening of TCM new drug.
