Abstract
Systematic chemotherapy has required high time span for recovery in cancer patients, serious toxic effects, and increased the time of cancer-free survival of patient but decreased the overall survival time of patients irrespective of diseased condition(s). To compare the quick recovery of inhalable doxorubicin and cisplatin in the lung cancer patients. A total of 240 patients with non-small cell lung cancer (NSCLC) patients were randomly divided into two groups of 120 each. Patients had inhaled 25 mg/m2 doxorubicin (DON group) or 10 mg/m2 cisplatin (CPN group) once in a day for 21 days. Volume, diameter, type, and a number of lung nodes, pulmonary function, and 21-day lung cancer risk assessment were evaluated. One-way ANOVA following Bonferroni multiple comparison tests was performed at 95% of confidence level. DON and CPN both groups had shrunken the lung cancer nodule, decreased solid nodules and non-solid nodules, and increased partially solid nodules. The DON group (5.88 ± 3.98%) had strongly decreased nodule size than the CPN group (4.15 ± 2.92%; p < 0.0001, q = 3.721). The incidence of nodular size reduction was 9.47 ± 1.13% higher for doxorubicin than cisplatin. The CPN group had 36.53 ± 0.66% and the DON group had 34.65 ± 0.7% lung cancer risk assessment after 21 days (p < 0.0001, q = 3.785). Inhalable doxorubicin might be an effective therapy in NSCLC patients with acceptable hematologic and non-hematologic toxic effects.

Abstract
Respiratory tract infections are one of the most frequent infections worldwide, with an increasing number being associated with (multiple) antibiotic-resistant pathogens. Improved treatment requires the development of new therapeutic strategies, including the possible development of antibiotic-nanomedicines. Antibiotic-nanomedicines comprise antibiotic molecules coupled to nanocarriers via surface adsorption, surface attachment, entrapment or conjugation and can be administered via aerosolization. The efficacy and tolerability of this approach has been shown in clinical studies, with amikacin liposome inhalation suspension being the first inhalatory antibiotic-nanomedicine approved by the US FDA. In this special report, we summarize and discuss the potential value and the clinical status of antibiotic-nanomedicines for the treatment of (antibiotic-resistant) respiratory tract infections.

Abstract
Electrospraying (ES) is a robust and versatile technique for the fabrication of micro- and nanoparticulate materials of various compositions, morphologies, shapes, textures and sizes. The physics of ES provides a great degree of flexibility towards the materials design of choice with desired physicochemical and biological properties. Not surprising, this technology has become an important tool for the production of micro- and nanostructured materials, especially in the pharmaceutical and biomedical arena. In this review, a basic introduction to the fundamentals of ES along with a brief description of the experimental parameters that can be manipulated to obtain micro- and nanostructured materials of desired composition, size, and configuration are outlined. A greater focus of this review is to bring to light the broad range of electrosprayed materials and their applications in drug delivery, biomedical imaging, implant coating, tissue engineering, and sensing. Taken together, this review will provide an appreciation of this unique technology, which can be used to fabricate micro- and nanostructured materials with tremendous applications in the pharmaceutical and biomedical fields.

Abstract
Background: Inhaled chemotherapeutics may enhance pulmonary drug exposure to malignant lesions in the lung without substantially contributing to systemic toxicities. The pharmacokinetic profile of inhaled submicron particle paclitaxel (NanoPac®) in healthy rodent plasma and lung tissue is evaluated here to determine administration proof-of-principle. Methods: Healthy male Sprague Dawley rats received paclitaxel in one of three arms: intravenous nab-paclitaxel at 2.9 mg/kg (IVnP), inhaled NanoPac low dose (IHNP-LD) at 0.38 mg/kg, or inhaled NanoPac high dose (IHNP-HD) at 1.18 mg/kg. Plasma and lung tissue paclitaxel concentrations were determined using ultraperformance liquid chromatography tandem mass spectrometry from animals sacrificed at 10 time points ranging up to 2 weeks after administration. Peak concentration (Cmax), apparent residence half-life (T1/2), exposure (AUC(last)), and dose-normalized exposure (AUCD(last)) were determined. Pulmonary histopathology was performed on rats sacrificed at the 336-hour time point. Results: Paclitaxel was detectable and quantifiable in the rat lung for both inhaled NanoPac arms sampled at the final necropsy, 336 hours postadministration. Substantial paclitaxel deposition and retention resulted in an order of magnitude increase in dose-normalized pulmonary exposure over IVnP. Inhaled NanoPac arms had an order of magnitude lower plasma Cmax than IVnP, but followed a similar plasma T1/2 clearance (quantifiable only to 72 hours postadministration). Pulmonary histopathology found all treated animals indistinguishable from treatment-naive rats. Conclusion: In the rodent model, inhaled NanoPac demonstrated substantial deposition and retention of paclitaxel in sampled lung tissue. Further research to determine NanoPac's toxicity profile and potential efficacy as lung cancer therapy is underway.

Abstract
Intravenous (IV) topotecan is approved for the treatment of various malignancies including lung cancer but its clinical use is greatly undermined by severe hematopoietic toxicity. We hypothesized that inhalation delivery of topotecan would increase local exposure and efficacy against lung cancer while reducing systemic exposure and toxicity. These hypotheses were tested in a preclinical setting using a novel inhalable formulation of topotecan against the standard IV dose. Respirable dry-powder of topotecan was manufactured through spray-drying technology and the pharmacokinetics of 0.14 and 0.79 mg/kg inhalation doses were compared with 0.7 mg/kg IV dose. The efficacy of four weekly treatments with 1 mg/kg inhaled vs. 2 mg/kg IV topotecan were compared to untreated control using an established orthotopic lung cancer model for a fast (H1975) and moderately growing (A549) human lung tumors in the nude rat. Inhalation delivery increased topotecan exposure of lung tissue by approximately 30-fold, lung and plasma half-life by 5- and 4-folds, respectively, and reduced the maximum plasma concentration by 2-fold than the comparable IV dose. Inhaled topotecan improved the survival of rats with the fast-growing lung tumors from 7 to 80% and reduced the tumor burden of the moderately-growing lung tumors over 5- and 10-folds, respectively, than the 2-times higher IV topotecan and untreated control (p < .00001). These results indicate that inhalation delivery increases topotecan exposure of lung tissue and improves its efficacy against lung cancer while also lowering the effective dose and maximum systemic concentration that is responsible for its dose-limiting toxicity.

Abstract
Background Improvement in drug accumulation in the lungs through inhalation administration and high expression of MMP2 and MMP9 in lung tumors have both been widely reported. Methods MMP2/9-triggered-release micelles were constructed and in vitro and in vivo studies of inhalation administration against lung tumor carried out. Pluronic P123 (P123) was modified with GPLGIAGQ-NH2 (GQ8) peptide to obtain P123-GQ8 (PG). MMP2/9-triggered-release micelles were constructed using PG and succinylated gelatin (SG) and loading paclitaxel (Ptx). To study biodistribution of micelles, DiR encapsulated in micelles was dosed to rats via intravenous injection or inhalation before ex vivo imaging for detecting DiR quantity in lungs. And B16F10 lung cancer-bearing nude mice were chosen as animal models to evaluate in vivo efficacy of MMP2/9-triggered-release micelles. Results Ptx-release efficiency from PG-SG-Ptx micelles was MMP2/9-concentration-dependent. For A549 cells, PG-SG-Ptx cytotoxicity was significantly greater (P<0.001) compared to P123-Ptx. Aerosol inhalation was chosen as the method of administration. In biodistribution experiment, DiR quantity in lungs was 5.8%±0.4% of that in major organs, while the ratio was 38.8%±0.5% for inhalation. For B16F10 lung cancer-bearing nude mice, the efficacy of inhalation of PG-SG-Ptx was significantly higher (P<0.001) than Taxol inhalation and injected PG-SG-Ptx. Inhaled PG-SG-Ptx also significantly inhibited the expression of Pgp in lung cancer. Conclusion Inhalation of MMP2/9-triggered-release micelles increased tumor sensitivity to chemotherapeutics and reduced the toxicity of chemotherapy to healthy lung cells, which has great potential in lung cancer therapy.

Abstract
Lung cancer is a highly invasive and prevalent disease with ineffective first-line treatment and remains the leading cause of cancer death in men and women. Despite the improvements in diagnosis and therapy, the prognosis and outcome of lung cancer patients is still poor. This could be associated with the lack of effective first-line oncology drugs, formation of resistant tumors and non-optimal administration route. Therefore, the repurposing of existing drugs currently used for different indications and the introduction of a different method of drug administration could be investigated as an alternative to improve lung cancer therapy. This review describes the rationale and development of repositioning of drugs for lung cancer treatment with emphasis on inhalation. The review includes the current progress of repurposing non-cancer drugs, as well as current chemotherapeutics for lung malignancies via inhalation. Several potential non-cancer drugs such as statins, itraconazole and clarithromycin, that have demonstrated preclinical anti-cancer activity, are also presented. Furthermore, the potential challenges and limitations that might hamper the clinical translation of repurposed oncology drugs are described.

Abstract
INTRODUCTION Routine inpatient care (RIC) for patients with cancer forms various pathways of clinical procedures. Although most individual procedures comprising the pathways have been tested via clinical trials, little is known about the collective cost and effectiveness of the pathways as a whole. This study aims at exploring RIC pathways for patients with lung cancer from rural Anhui, China, and their determinants and economic impacts. METHODS AND ANALYSIS The study adopts a retrospective cohort design and proceeds in five steps. Step 1 defines the four main categories of study variables, including clinical procedures, direct cost and effectiveness of procedures, and factors affecting use of these procedures and their cost and effectiveness. Step 2 selects a cohort of 5000 patients with lung cancer diagnosed between 1 July 2015 and 30 June 2016 from rural Anhui by clustered random sampling. Step 3 retrieves the records of all the inpatient care episodes due to lung cancer and extracts data about RIC procedures, proximate variables (eg, Karnofsky Performance Status, Lung Function Score) of patient outcomes and related factors (eg, stage of cancer, age, gender), by two independent clinician researchers using a web-based form. Step 4 estimates the direct cost of each of the RIC procedures using micro-costing and collects data about ultimate patient outcomes (survival and progression-free survival) through a follow-up survey of patients and/or their close relatives. Step 5 analyses the data collected and explores pathways of RIC procedures and their relations with patient outcomes, costs, cost:effect ratios, and a whole range of clinical and sociodemographic factors using multivariate regression and path models. ETHICS AND DISSEMINATION The study protocol has been approved by an authorised ethics committee of Anhui Medical University (reference number: 20170312). Findings from the study will be disseminated through conventional academic routes such as peer-reviewed publications and presentations at regional, national and international conferences. TRIAL REGISTRATION NUMBER ISRCTN25595562.

Abstract
Inhaled chemotherapy for the treatment of lung tumors requires that drug delivery systems improve selectivity for cancer cells and tumor penetration and allow sufficient lung residence. To this end, we developed solid lipid nanoparticles (SLN) with modified surface properties. We successfully synthesized a new folate-grafted copolymer of polyethylene glycol (PEG) and chitosan, F-PEG-HTCC, with a PEG-graft ratio of 7% and a molecular weight range of 211-250 kDa. F-PEG-HTCC-coated, paclitaxel-loaded SLN were prepared with an encapsulation efficiency, mean diameter, and zeta potential of about 100%, 250 nm, and +32 mV, respectively. The coated SLN entered folate receptor (FR)-expressing HeLa and M109-HiFR cells in vitro and M109 tumors in vivo after pulmonary delivery. The coated SLN significantly decreased the in vitro half-maximum inhibitory concentrations of paclitaxel in M109-HiFR cells (60 vs 340 nM, respectively). We demonstrated that FR was involved in these improvements, especially in M109-HiFR cells. After pulmonary delivery in vivo, the coated SLN had a favorable pharmacokinetic profile, with pulmonary exposure to paclitaxel prolonged to up to 6 h and limited systemic distribution. Our preclinical findings therefore demonstrated the positive impact of the coated SLN on the delivery of paclitaxel by inhalation.
