Chinese Traditional and Herbal Drugs 1994;0(10):-
Objective To study the control effect of Trichoderma fungicides in the field and then popularize the using. Methods To investigate the influence by three using methods and different concentrations of the two Trichoderma strains on ginseng growth and its diseases, estimate the possibility of popular using the fungicide, and make a choice of the right using method. Results The two fungicides not only could raise the survival rate by 30% and the growing rate by more than 16%, but also effectively control the disease of ginseng. Conclusion The two Trichoderma fungicides have the potential to be used in a large range. The using method is diluting Tv04-2 to 5 000 times and Th3080 to 10 000 times when dipping the root of ginseng, and diluting Tv04-2 or Th3080 to 5 000 times when dipping the seeds of ginseng.

The FOXO3a and FOXM1 forkhead transcription factors are key players in cancer initiation, progression, and drug resistance. Recent research shows that FOXM1 is a direct transcriptional target of FOXO3a, a vital downstream effector of the PI3K-AKT-FOXO signaling cascade. In addition, FOXM1 and FOXO3a also antagonize each other's activity by competitively binding to the same target genes, which are involved in chemotherapeutic drug sensitivity and resistance. Understanding the role and regulation of the FOXO-FOXM1 axis will provide insight into chemotherapeutic drug action and resistance in patients, and help to identify novel therapeutic approaches as well as diagnostic and predictive biomarkers.

A method of high performance liquid chromatography coupled with time-of-flight mass spectrometry was used to detect the endogenous metabolites changes in plasma of normal rats, rats of dampness stagnancy due to spleen deficiency and Astragalus flavone component intervention rats. Metabolism map of rat plasma was obtained and the mechanism of Astragalus flavonoids on dampness stagnancy due to spleen deficiency was studied. Rat model with dampness stagnancy due to spleen deficiency was established by high fat and low protein diet plus load swimming. Liquid chromatography tandem mass spectrometry was used for the analysis of rat plasma sample, and 0.05% formic acid water with 0.05% formic acid acetonitrile as the mobile phase was applied in gradient elution with Halo C18 chromatographic column. In this study, partial least squares discriminant analysis and variance analysis were used to screen the potential biomarkers, it was found that the metabolic profile of the Astragalus flavonoids was different from that of the model group, which was close to that of the normal group. A total of 11 potential biomarkers were identified, including glycerol phospholipids, sphingolipids, amino acids, and so on. The metabolic pathways of biomarkers including three tricarboxylic acid cycle, glycerol phospholipid metabolism, fatty acid metabolism, amino acid metabolism and so on, which mainly related to energy metabolism and fat metabolism in the body. Related indexes of rats with syndrome of spleen deficiency of water and dampness were significantly callback after Astragalus flavone intervention, including macro indicators such as body weight, independent activities and micro indicators such as metabolic markers, blood lipids and others. The result showed that Astragalus flavonoids played the role of strengthening the spleen and draining the water mainly through regulating the energy metabolism, fat metabolism and so on.

The popularization of medical insurance in Panama has been basically completed. The coverage of health insurance is high, but with the problem of polarization. The major causes of death in Panama are is chemic heart disease, stroke, AD and diabetes. In recent years, the chronic kidney disease and COPD are increasing significantly. Panamanian native medicine, considered as complementary and alternative medicine, is recognized by local laws and usedby most of indigenous groups and rural people. Traditional Chinese Medicine (TCM) in Panama is at the starting stage, and there is no relevant legislation. However, this country attaches great importance to indigenous traditional medicine, and more and more people gradually accept it. TCM has great development potential in this country. It is suggested to promote the development of TCM in Panama. By culture as the pathway, exploring various forms of cooperation and exchange, taking the research and development of traditional herbal medicine as the breakthrough point, and increasing the spead of acupuncture usage, etc.

Objective:To investigate the safety and efficacy of balloon pulmonary angioplasty (BPA) for residual pulmonary hypertension (PH) of chronic thromboembolic pulmonary hypertension(CTEPH) after pulmonary endarterectomy (PEA).Methods:Patients diagnosed as PH after PEA in China-Japan Friendship Hospital from Oct 2016 to Jun 2022 were included. The indication for BPA was decided on the basis of a consensus of the multi-disciplinary team for all patients with CTEPH. Before treatment, the patient′s exercise tolerance and pulmonary artery flow parameters were evaluated. A comparative analysis of various parameters before BPA treatment and at the last BPA was conducted. 6-min walk distance (6MWD) was analyzed using the paired Wilcoxon test; N-terminal pro-brain natriuretic peptide (NT-proBNP), mixed venous oxygen saturation, mean pulmonary arterial pressure (mPAP), cardiac index (CI) and pulmonary vascular resistance (PVR) were compared using the paired-samples t-test. WHO functional class was compared using McNemar′s test. Results:Twenty patients with a total of 130 vessels underwent 46 sessions of BPA treatment. The postoperative 6-minute walk distance (6MWD) [447 (415, 485) m] showed a significant improvement compared to the preoperative baseline [389 (335, 470) m] ( Z=6.52, P<0.05), Postoperative mixed venous oxygen saturation (72.0%±1.9%) showed a significant improvement compared to the preoperative levels (64.0%±2.7%) ( t=2.14, P<0.05).Postoperatively, plasma NT-proBNP [(351.9±129.9) pg/ml], mPAP [(24.2±1.9) mmHg], and PVR [(3.0±1.4) WU] significantly decreased compared to preoperative levels [(982.5±426.2) pg/ml, (33±2.1) mmHg, (8.0±1.6) WU)] ( t=3.38, 1.22, 2.10, P<0.05 for all). Postoperatively, there was a significant improvement in WHO functional class (Ⅰ,Ⅱ,Ⅲ,Ⅳ: 14, 4, 2, 0 cases) compared to preoperative status (Ⅰ,Ⅱ,Ⅲ,Ⅳ: 0, 13, 5, 2 cases) ( χ2=20.17, P<0.05). Four cases of pulmonary artery dissection and one episode of hemoptysis occurred postoperatively, with no other complications reported. Conclusions:BPA can significantly improve exercise tolerance and hemodynamic parameters for residual PH after PEA. BPA is a relatively safe and effective treatment for residual PH after PEA.
