Photodynamic therapy (PDT) is a potential treatment strategy for melanoma. As a second-generation photosensitizer, Zinc phthalocyanine (ZnPc) has many advantages for anti-tumor PDTs, such as strong absorption in the red and near infrared regions, high photo and chemical stability, etc. However, ZnPc has a poor water solubility and is apt to aggregate due to the π-π interaction between molecules, which limits its applications. In this study, various solvents and surfactants were screened for dissolving ZnPc and preparing ZnPc@SDC-TPGS micelle and thermosensitive in situ gel. After the cytotoxic effects of thermosensitive gels on PDT were tested, the antitumor effects on PDT of them in mice by intratumoral injection were evaluated, including body weight, and tumor weight, volume and morphology. The cell death pathway and the relationship of reactive oxygen species yield with apoptotic rate of tumor cells induced by ZnPc in situ gel were investigated. The results were that N-methyl-pyrrolidone (NMP) mixed with 2 % SDC and aqueous solution containing 2 % TPGS and 2 % SDC were used to synthesize ZnPc@SDC-TPGS micelle and the thermosensitive in situ gel. The cytotoxic effects of thermosensitive gels showed good tumor suppression of ZnPc@SDC-TPGS in situ gel and no toxicity of the blank gel. Intratumoral injection in situ gel containing 3 µg ZnPc under irradiation demonstrated good tumor inhibition in mice with melanoma. Apoptosis has been established as the primary pathway of cell death, and the production of reactive oxygen species (ROS) plays a crucial role in cellular apoptosis induced by ZnPc@SDC-TPGS in situ gel. In conclusion, the intratumoral injection of ZnPc@SDC-TPGS thermosensitive in situ gel provides a promising local treatment option for melanoma.
Background: Chemotherapy-induced myelosuppression (CIM) is a common adverse reaction with a high incidence rate that seriously affects human health. Shengyu Decoction (SYD) is often used to treat CIM. However, its pharmacodynamic basis and therapeutic mechanisms remain unclear. Purpose: This study aimed to clarify the active components and mechanisms of SYD in CIM. Methods: LC-QTOF/MS was used to identify the absorbable components of SYD. A series of network pharmacology methods have been applied to explore hub targets and potential mechanisms. Molecular docking was used to identify the binding ability of potential active ingredients and hub targets. Finally, in vitro experiments were performed to validate these findings. Results: In this study, 33 absorbable prototype components were identified using LC-QTOF/MS. A total of 62 possible targets of SYD in myelosuppression were identified. KEGG pathway enrichment analyses showed that some signaling pathways such as PI3K-Akt and HIF-1 may be the mechanisms by which it functions. Among them, we verified the PI3K-Akt pathway. 6 Hub proteins were screened by Protein-protein interaction (PPI) network analysis. Molecular docking results showed that four absorbable components in SYD showed good binding with six Hub targets. The effectiveness of the four predicted compounds and the mechanism were verified in vitro. It has also been shown that the active component could promote the proliferation of bone marrow stromal cells (BMSCs) and block apoptosis of BMSCs, which may be related to the PI3K-Akt pathway. This result is consistent with the network pharmacology approach and molecular docking predictions. Conclusion: Our results provided not only the candidate active component of SYD, but also a new insights into mechanism of SYD in the treatment of CIM.

糖尿病的发病机制复杂,降糖治疗需要根据病人情况的不同选择作用机制不同的药物,或单药治疗,或联合用药.但是,很多患者都认为最好的药才是最正确的选择.对于糖尿病的治疗,什么药才是“最好的药”,并非一个简单的问题.糖尿病的管理也不仅仅是控制血糖,而是一个全方位的综合管理过程,治疗中需要平衡获益与风险,减少低血糖发生率,减少血糖波动,维持合理的体重.
天气炎热干燥时,如果体内热量不能充分排出,积蓄到一定程度时就会引起中暑.除了气温过高、人体产热增加、散热障碍、汗腺功能障碍等因素外,一些药物也会增大中暑风险,使用时应格外小心. [降压药]当气温较高时,会引起血管扩张,服用降压药尤其是利尿药之后,会使排尿增多,机体容易出现脱水和电解质失衡,可能引起乏力、倦怠、食欲不振、心慌等中暑症状.因此服用降压药后要及时补充水分,必要时在医生指导下调整剂量.
进入冬季,天气干燥,气温下降,鼻炎、咽喉炎等疾病盯上了不少人,不仅影响生活,对身体还有伤害.那么此时应该如何正确用药呢? 鼻炎:鼻塞少用滴鼻剂 很多人进入冬季后总感觉鼻子干,如果呼吸道功能较差的人在这个季节里,鼻炎是很容易复发的. 分析:鼻炎的症状为进行性鼻塞、流涕,伴有轻度发热、乏力、头痛等.患者一旦出现上述症状并反复发作,应提高警惕,及时就医,不要在家乱服药,以免使病情迁延.

在日常生活中,有人经常会因为种种原因漏服药物,特别是一些需要长期服药的糖尿病、高血压、血脂异常等慢性病患者。如果遇到漏服的情况,要视药物的种类和具体情况选择补服的办法。
在日常生活中,有人经常会因为种种原因漏服药物,特别是一些需要长期服药的糖尿病、高血压、高血脂等慢性病患者.实际上,漏服药物会对血压、血糖的控制造成影响.此时有的患者会选择多吃一次,将上次漏掉的补上.这样做科学吗? 随意补服和加量药物,对健康无益.如果遇到漏服的情况,要视药物的种类和具体情况选择补服的办法.但无论是哪种情况,都不建议"合二为一"加量补服,以免出现药物不良反应,甚至引起药物中毒.
Objective To investigate the characteristics and regular pattern of the adverse drug reactions(ADR)occurred in our hospital in order to promote clinical rational drug use.Methods By a descriptive study,the ADR reports of 190 cases collected from 2006 to 2009 in our hospital were analyzed statistically.Results The ADR were induced by 16 categories(86 kinds)of drugs,predominantly by the anti-microbial agents(25 kinds,86 cases),followed by cardiovascular system agents and nervous system agents(27 cases and 21 cases);the ADR of 65 cases manifested chiefly as lesions of skin and its appendages.Conclusion Great importance should attached to ADR monitoring and reporting timely so as to reduce or avoid the repeated occurrence of ADR,and promote clinical rational drug use.
