BACKGROUND:It is reported that gelatin sponge particles and chitosan/α, β-glycerophosphate gel microspheres have high application prospects in the treatment of hemoptysis of pulmonary tuberculosis.METHODS: Forty SPF Kunming mice were selected to make animal models of pulmonary tuberculosis hemoptysis using aerosolized inhalation device and randomly divided into two groups undergoing embolization for hemostasis using gelatin sponge particles and chitosan/α, β-glycerophosphate gel microspheres, respectively. Body mass changes, hemostasis time, effective rate of hemostasis, related indexes of myocardium and pathological changes of pulmonary tuberculosis were observed at 15 and 30 days after treatment.RESULTS AND CONCLUSION:(1) Mice in the chitosan/α, β-glycerophosphate gel microspheres group had higher body mass than those in the gelatin sponge group at 15 days after treatment (P < 0.05). (2) Compared with the gelatin sponge group, the hemostatic efficiency was higher and the time of hemostasis was shorter in the chitosan/α, β-glycerophosphate gel microspheres group (P< 0.05). (3) There were no significant differences in the levels of BNP precursor, creatine kinase isoenzyme and creatine kinase between the two groups (P > 0.05). (4) The lymphocyte infiltration and necrotic lesions were found around the microspheres, necrotic lesions were found, and there were a lot of active cells on the microspheres. There were a few lymphocytes in the gelatin sponge group. These results show that that the chitosan/α, β-glycerophosphate gel microspheres have better hemostatic effects in comparison with gelatin sponge particles in a mouse model of pulmonary tuberculosis.

We revisited the "Xiao Chaihu Decoction event (XCHDE)" occurred in late 1980s in Japan and the Bupleuri Radix related adverse drug reaction (ADR) reports in China After careful review, comparison, analysis and evaluation, we think the interstitial pneumonitis, drug induced Liver injury (DILI) and other severe adverse drug envents (ADEs) including death happened in Japan is probably results from multiple factors, including combinatory use of XCHDE with interferon, Kampo usage under modern medicine theory guidance, and use of XCHD on the basis of disease diagnosis instead of traditional Chinese syndrome complex differentiation. There are less ADE case reports related to XCHD preparation in China compared to Japan, mostly manifest with hypersensitivity responses of skin and perfuse perspiration. The symptoms of Radix Bupleuri injection related ADEs mainly manifest hypersensitivity-like response, 2 cases of intravenous infusion instead of intramuscular injection developed hypokalemia and renal failure. One case died from severe hypersensitivity shock. In Chinese literatures, there is no report of the interstitial pneumonitis and DILI associated with XCHDG in Japan. So far, there is no voluntary monitoring data and large sample clinical research data available. The author elaborated the classification of "reevaluation" and clarified "re-evaluation upon events" included the reaction to the suspected safety and efficacy events. Based on the current status of the clinical research on the Radix Bupleuri preparations, the author points out that post-marketing "re-evaluation upon suspected event" is not only a necessity of continuous evaluation of the safety, efficacy of drugs, it is also a necessity for providing objective clinical research data to share with the international and domestic drug administrations in the risk-benefit evaluation. It is also the unavoidable pathway to culture and push the excellent species and famous brands of TCM to the international market, in that it enhances the pharmaceutical manufactures the ability to control enterprise risk and eliminate the negative impact on traditional Chinese medicine. With the widely used and ADR report concentrated Radix Bupleuri injection as an example, the author provide a new approach to post-marketing clinical research.

Based on the literature study,the thoughts and possible therapeutic mechanism in treating male infertility from the perspective of spleen and kidney by regulating intestinal flora were explored.Disturbance of intestinal flora is one of the important factors leading to the development of male infertility,and the spleen and kidney have certain similarities to intestinal flora in the physiological function and pathological changes.Moreover,tonifying the kidney and strengthening the spleen can regulate the intestinal flora by fostering the growth of beneficial bacteria,inhibiting the reproduction of pathogenic bacteria,and protecting the barrier of the intestinal mucosa.Therefore,the possible therapeutic mechanisms in treating male infertility with the prescriptions for tonifying the kidney and strengthening the spleen to regulate intestinal flora are as follows:inhibiting the expression of inflammatory factors to reduce the inflammatory reaction of testicular tissues;improving the antioxidant capacity to alleviate the damage of spermatozoa caused by oxidative stress,and improving the bad mood to alleviate the impact of psychological stress on the reproductive system.The exploration of the thoughts for treating male infertility from the perspective of spleen and kidney by regulating intestinal flora may provide a new entry point for modern Chinese medicine clinical treatment of male infertility.

Growth suitability as assessment indicators for medicinal plants cultivation was proposed based on chemical quality determination and ecological factors analysis by Maxent and ArcGIS model. Notopterygium incisum, an endangered Chinese medicinal plant, was analyzed as a case, its potential distribution areas at different suitability grade and regionalization map were formulated based on growth suitability theory. The results showed that the most suitable habitats is Sichuan province, and more than 60% of the most suitable areawas located in the western Sichuan such as Aba and Ganzi prefectures for N. incisum. The results indicated that habitat altitude, average air temperature in September, and vegetation types were the dominant factors contributing to the grade of plant growth, precipitation and slope were the major factors contributing to notopterol accumulation in its underground parts, while isoimperatorin in its underground parts was negatively corelated with precipitation and slope of its habitat. However, slope as a factor influencing chemical components seemed to be a pseudo corelationship. Therefore, there were distinguishing differences between growth suitability and quality suitability for medicinal plants, which was helpful to further research and practice of cultivation regionalization, wild resource monitoring and large-scale cultivation of traditional Chinese medicine plants.

Despite strict pre- and post-transplantation screening, the incidence of new-onset diabetes after transplantation (NODAT) remains as high as 60%. This complication affects the risk of cardiovascular events and patient and graft survival rates. Thus, reducing the impact of NODAT could improve overall transplant success. The pathogenesis of NODAT is multifactorial, and both modifiable and nonmodifiable risk factors have been implicated. Monitoring and controlling the blood glucose profile, implementing multidisciplinary care, performing lifestyle modifications, using a modified immunosuppressive regimen, administering anti-metabolite agents, and taking a conventional antidiabetic approach may diminish the incidence of NODAT. In addition to these preventive strategies, inhibition of dipeptidyl peptidase-4 (DPP4) by the gliptin family of drugs has recently gained considerable interest as therapy for type 2 diabetes mellitus and NODAT. This review focuses on the role of DPP4 inhibitors and discusses recent literature regarding management of NODAT.
