Abstract
Breast cancer is a major threat to health and lives of females. Biomimetic nanotechnology brought brighter hope for early diagnosis and treatment of breast cancer. Here, we proposed a platelet (PLT) membrane-derived strategy for enhanced photoacoustic (PA)/ultrasonic (US)/fluorescence (FL) multimodal imaging and augmented synergistic photothermal/chemotherapeutic efficacy in tumor cells. A PA imaging contrast and photothermal agent, nanocarbons (CNs), a chemotherapeutic and FL material, doxorubicin (DOX), and perfluoropentane (PFP) were coencapsulated into the poly(lactic-co-glycolic) acid (PLGA) skeletons. Then, the PLT membranes were coated onto the PLGA NPs, which were named as "nanoplatelets" (DOX-PFP-CNs@PLGA/PM NPs). The "nanoplatelets", which conserved the structural advantages and inherent properties of PLTs, could not only escape from phagocytosis of macrophages but also actively targeted tumor cells by the way of antigen-antibody interactions between P-selectin on the PM and CD44 receptors of the tumor cells. With CNs and DOX loaded in, these "nanoplatelets" could serve as an excellent contrast agent for PA/FL imaging. Under laser irradiation, the "nanoplatelets" could turn light energy into heat energy. The laser-triggered photothermal effect, on the one hand, could ablate the tumor cells immediately, and on the other hand, could initiate the optical droplet vaporization of PFP, which subsequently enhanced US imaging and promoted the discharge of encapsulated DOX from the "nanoplatelets" for remarkably strengthening photothermal therapeutic power in turn. In this work, as compared with the bare drug-loaded nanoparticles, the "nanoplatelets" exhibited much more accumulation in the tumor cells, demonstrating superior multimodal imaging capability and preferable synergistic therapeutic performance. In conclusion, the "nanoplatelets" could serve as contrast agents for US imaging and PA imaging to guide the therapy. What is more, the bioinspired PLT-derived, targeted, and nontoxic "nanoplatelets", which were exploited for multimodal PA/US/FL imaging-guided synergistic photothermal/chemo therapy, will be of great value to breast cancer theranostics in the days to come.

Abstract
This study aimed to compare the postoperative effects of total parathyroidectomy plus forearm transplantation and radioguided parathyroidectomy on bone metabolism and bone mineral density (BMD). From June 2013 to October 2017, 67 patients with renal secondary hyperparathyroidism (SHPT) received surgical treatment. The control group included 30 cases of classical total parathyroidectomy plus forearm transplantation for SHPT. In the experimental group, 37 patients underwent 99mTc-MIBI-guided parathyroidectomy. Demographics, parathyroid hormone (PTH) level, blood calcium level, and pathological results were compared between the 2 groups. The curative effect of parathyroidectomy and its effect on BMD were also compared. The BMDs in the L1-L4 segments and femoral neck in both groups were significantly improved after operation (all P < .05). The T scores of the L1-L4 segments and femoral neck in both groups were significantly improved after operation (all P < .05). The improvement in the T score of the L4 in the experimental group was significantly higher than that in the control group (P < .05). No significant differences in the improvement in the L1-L3 segments and femoral neck were found between the 2 groups. Both traditional total parathyroidectomy plus forearm transplantation and 99mTc-MIBI-guided parathyroidectomy can improve PTH level, blood calcium level, phosphorus level, bone metabolism, and BMD to varying degrees in patients with SHPT. Compared with the traditional surgery, 99mTc-MIBI-guided parathyroidectomy can improve blood calcium and phosphorus metabolisms, reduce PTH level, and improve the T scores of L4 to a greater extent.

Abstract
We present the case of a 13-year-old boy with bleeding complications from a Meckel diverticulum (MD), which was scintigraphically confirmed. A first exploratory laparoscopy was unsuccessful in identifying the diverticulum. A new Tc-pertechnetate scintigraphy (including SPECT/CT), 3 years later, suggested the anatomical location and was helpful during the surgical exploration for the MD by radioguided surgery. Radioguidance is helpful in pathologies characterized by small size or variable anatomical location. A MD with ectopic gastric mucosa can be distinguished from the rest of the small bowel based on selective Tc-pertechnetate uptake in the gastric mucosa, with limited background activity.

Application of carbon nanoparticles in localization of parathyroid glands during total parathyroidectomy for secondary hyperparathyroidism. Am J Surg 2020; 220:1586-1591.

Abstract
BACKGROUND Intraoperative imaging is used to address the challenges of parathyroidectomy, but no standard modality has been established. This study aimed to assess whether carbon nanoparticle injection is useful in localizing parathyroid glands (PGs) during parathyroidectomy. METHODS Patients who underwent total parathyroidectomy (TPTX) between September 2015 and November 2018 were included. The operative duration and intact parathyroid hormones (iPTH) were analyzed. RESULTS A total of 61 patients were included; of these, 32 with carbon nanoparticle injection (TPTX + CN group) and 29 without (TPTX group). The operative duration in the TPTX + CN group was significantly shorter (90.6 ± 21.2 vs 101.4 ± 19.4 min, P = 0.042), which is more apparent in those with normal sized PGs. For those with four enlarged PGs, iPTH levels on 1 day and 1 year postoperatively were significantly lower in the TPTX + CN group (P = 0.032 and P = 0.036, respectively). CONCLUSION Carbon nanoparticles are useful in the identification normal sized PGs and complete resection of enlarged PGs.

Molecules 2020; 25:E1724.

Abstract
Accurate pre-operative determination of parathyroid glands localization is critical in the selection of minimally invasive parathyroidectomy as a surgical treatment approach in patients with primary hyperparathyroidism (PHPT). Its importance cannot be overemphasized as it helps to minimize the harmful side effects associated with damage to the parathyroid glands such as in hypocalcemia, severe hemorrhage or recurrent laryngeal nerve dysfunction. Preoperative and intraoperative methods decrease the incidence of mistakenly injuring the parathyroid glands and allow for the timely diagnosis of various abnormalities, including parathyroid adenomas. This article reviews 139 studies conducted between 1970 and 2020 (49 years). Studies that were reviewed focused on several techniques including application of carbon nanoparticles, carbon nanoparticles with technetium sestamibi (99m Tc-MIBI), Raman spectroscopy, near-infrared autofluorescence, dynamic optical contrast imaging, laser speckle contrast imaging, shear wave elastography, and indocyanine green to test their potential in providing proper parathyroid glands' localization. Apart from reviewing the aforementioned techniques, this study focused on the applications that helped in the detection of parathyroid adenomas. Results suggest that applying all the reviewed techniques significantly improves the possibility of providing proper localization of parathyroid glands, and the application of indocyanine green has proven to be the 'ideal' approach for the diagnosis of parathyroid adenomas.
