Objective To evaluate the influence of Chinese patent medicine Banlangen Granules and Ganmao Qingre Granules on war‐farin anticogulation effect during the process for treating acute upper respiratory tract infection in the postoperative patients with mechanical valve replacement in order to provide the theoretical reference for clinical medication .Methods The patient receiving mitral valve replace‐ment ,aortic valve replacement or double‐valve replacement and long term postoperative oral warfarin anticoagulation treatment were select‐ed ,moreover the symptoms of complicating acute upper respiratory tract infection occurred .The patients were divided into 2 groups ,30 cases in each group .The group A adopted oral Banlangen Granules ,while the group B was treated by oral Ganmao Qingre Granules .The treat‐ment course was 3 d .The International Normalized Ratio (INR) in the two groups was monitored before medication ,at 72 h after medication and at 72 h after drug withdrawal .Complicating bleeding or embolism reaction was observed .The INR values at various time points were compared between the two groups and the INR values in each group were compared among 3 time points .Results The INR values in the Banlangen Granules group had statistical differences between 72 h and other two time points ,and the INR values at the same time point had statistical difference compared with the Ganmao Qingre Granules group (P<0 .05);the INR value in the Banlangen Granules group had no statistical difference between before medication and at 72 h after medication(P>0 .05) .Thirty cases had no complication occurrence .The Ganmao Qingre Granules group had no statistical difference among various time points (P>0 .05) ,thirty cases had no complication occur‐rence .Conclusion The warfarin combined with Banlangen Granules causes the INR value increase ,while warfarin combined with Ganmao Qingre Granules has no impact on the INR value ,therefore which suggests that the combination use of warfarin and Banlangen Granules should be cautious in clinic .

Objective To develop an effective treatment strategy to simultaneously avoid fatal adverse effects in the treatment of oral cancer, combination therapy has been explored because of its multiple functions. This work aims to develop a novel type of gold-nanorod-based nanomaterials decorated with tetrahedral DNA nanostructures (TDN) carrying antitumor drugs, namely, GNR@TDN-DOX nanocomposites. Methods In the designed structure, TDN, with a three-dimensional geometry composed of DNA strands, can provide GC base pairs for binding with the anticancer drug doxorubicin (DOX). The photothermal heating properties, biocompatibility properties, and antitumor performance of obtained GNR@TDN-DOX nanocomposites were investigated to assess their application potential in tumor treatment. Results Systematic studies have shown that the obtained GNR@TDN-DOX nanocomposites have high photothermal conversion under the illumination of an 808-nm infrared laser, leading to effective antitumor applications. In addition, the cell viability study shows that GNR@TDN-DOX nanocomposites have good biocompatibility. In vitro studies based on A375 cells show that the GNR@TDN-DOX nanocomposites can effectively eliminate cancer cells because of the combination of photothermal therapy induced by GNRS and chemotherapy induced by TDN-carrying DOX. The result shows that the obtained GNR@TDN-DOX nanocomposites have efficient cellular uptake and lysosome escape ability, together with their nuclear uptake behavior, which results in a significant antitumor effect. Conclusion This work has demonstrated a potential nanoplatform for anticancer applications.

Numerous randomised controlled trials have suggested the positive effects of acupuncture on chronic obstructive pulmonary disease (COPD). However, the underlying therapeutic mechanisms of acupuncture for COPD have not been clearly summarized yet. Inflammation is central to the development of COPD. In this review, we elucidate the effects and underlying mechanisms of acupuncture from an anti-inflammatory perspective based on animal studies. Cigarette smoke combined with lipopolysaccharide is often used to establish animal models of COPD. Electroacupuncture can be an effective intervention to improve inflammation in COPD, and Feishu (BL13) and Zusanli (ST36) can be used as basic acupoints in COPD animal models. Different acupuncture types can regulate different types of inflammatory cytokines; meanwhile, different acupuncture types and acupoint options have similar effects on modulating the level of inflammatory cytokines. In particular, acupuncture exerts anti-inflammatory effects by inhibiting the release of inflammatory cells, inflammasomes and inflammatory cytokines. The main underlying mechanism through which acupuncture improves inflammation in COPD is the modulation of relevant signalling pathways: nuclear factor-κB (NF-κB) (e.g., myeloid differentiation primary response 88/NF-κB, toll-like receptor-4/NF-κB, silent information regulator transcript-1/NF-κB), mitogen-activated protein kinase signalling pathways (extracellular signal-regulated kinase 1/2, p38 and c-Jun NH2-terminal kinase), cholinergic anti-inflammatory pathway, and dopamine D2 receptor pathway. The current synthesis will be beneficial for further research on the effect of acupuncture on COPD inflammation.

Bone regeneration remains a great clinical challenge. Low intensity near-infrared (NIR) light showed strong potential to promote tissue regeneration, offering a promising strategy for bone defect regeneration. However, the effect and underlying mechanism of NIR on bone regeneration remain unclear. We demonstrated that bone regeneration in the rat skull defect model was significantly accelerated with low-intensity NIR stimulation. In vitro studies showed that NIR stimulation could promote the osteoblast differentiation in bone mesenchymal stem cells (BMSCs) and MC3T3-E1 cells, which was associated with increased ubiquitination of the core circadian clock protein Cryptochrome 1 (CRY1) in the nucleus. We found that the reduction of CRY1 induced by NIR light activated the bone morphogenetic protein (BMP) signaling pathways, promoting SMAD1/5/9 phosphorylation and increasing the expression levels of Runx2 and Osterix. NIR light treatment may act through sodium voltage-gated channel Scn4a, which may be a potential responder of NIR light to accelerate bone regeneration. Together, these findings suggest that low-intensity NIR light may promote in situ bone regeneration in a CRY1-dependent manner, providing a novel, efficient and non-invasive strategy to promote bone regeneration for clinical bone defects.
