Bone marrow mesenchymal stem cells-derived exosomes for penetrating and targeted chemotherapy of pancreatic cancer

Pancreatic ductal adenocarcinoma (PDAC) is one of the most intractable malignancy, with an only 6% 5-year relative survival rate. The dismal therapeutic effect is attributed to the chemotherapy resistance and unique pathophysiology with abundant inflammatory cytokines and abnormal hyperplasia of extracellular matrix (ECM). Based on the theory that bone marrow mesenchymal stem cells (BM-MSCs) can influence the tumorous microenvironment and malignant growth of PDAC, we employed exosomes (Exos) derived from BM-MSCs as PDAC-homing vehicles to surpass the restrictions of pathological ECM and increase the accumulation of therapeutics in tumor site. To overcome chemoresistance of PDAC, paclitaxel (PTX) and gemcitabine monophosphate (GEMP)-an intermediate product of gemcitabine metabolism-were loaded in/on the purified Exos. In this work, the Exo delivery platform showed superiorities in homing and penetrating abilities, which were performed on tumor spheroids and PDAC orthotopic models. Meanwhile, the favorable anti-tumor efficacy and , plus relatively mild systemic toxicity, was found. Loading GEMP and PTX, benefitting from the naturally PDAC selectivity, the Exo platform we constructed performs combined functions on excellent penetrating, anti-matrix and overcoming chemoresistance (Scheme 1). Worth expectantly, the Exo platform may provide a prospective approach for targeted therapies of PDAC.

Objective To evaluate the effect of CT-guided percutaneous coaxial needle biopsy combined with microwave ablation (MWA) for the treatment of lung tumors, and to discuss its technique, safety, curative effect and clinical application value. Methods A total of 20 patients with lung tumor, who were admitted to the Department of Interventional Radiology, Shanghai Ruijin Hospital, China, during the period from August 2014 to June 2016, were collected. Among the 20 patients, primary pulmonary cancer was diagnosed in 9 and metastatic tumor in 11. A total of 23 tumor lesions were detected, and CT-guided percutaneous coaxial needle biopsy combined with MWA was performed for all lesions. Based on the size and shape of the tumor, the corresponding ablation power and time of duration were set up. After the treatment, the patients were followed up for 4-26 months, and chest enhanced CT examination was regularly reexamined to assess the curative effect. Results Percutaneous coaxial needle biopsy was carried out for 23 lesions, the tumor diameters ranged from 0.80 cm to 2.40 cm, with a mean of 1.39 cm. MWA was employed for 23 lesions. CT scan performed immediately after MWA showed that the density of tumor lesion became decreased, the diagnostic positive rate of needle biopsy was 83.3％. After the treatment, complete remission was obtained in 15 patients, partial remission in 2 patients, stable disease in one patient, and progression.

Objective To investigate the feasibility and safety of portal 125I seed stent implantation combined with doxorubicin-eluting beads transcatheter arterial chemoembolization (DEB-TACE) for the treatment of hepatocellular carcinoma (HCC) associated with main portal vein tumor thrombus (MPVTF).Methods Prospective single-arm study was designed.Seven HCC patients with MPVTT were sequentially enrolled in this study to receive treatment.Portal pressure before and after portal vein stent implantation were determined,the liver function were tested before and 1-3 days,4 days,5-7 days after portal vein stent implantation,the results and the postoperative complications were analyzed.Results All 7 patients were in BCLC-C stage,with Child-Pugh classification being A-B level.All patients were diagnosed as massive type HCC complicated by portal vein tumor thrombus.The lesions were located in hepatic left lobe (n=l) and hepatic right lobe (n=6),tumor thrombus in left branch of portal vein was seen in one patient and tumor thrombus in right branch of portal vein was found in 6 patients,MPVTT was observed in all 7 patients.Portal 125I seed stent implantation plus DEB-TACE was successfully accomplished in all 7 patients.The portal pressure before and after stent implantation was 15.3 cmH2O and 10.2 cmH2O respectively,the postoperative pressure showed an obvious reduction.After stent implantation,a transient elevation of the serum total bilirubin (TB),alanine aminotransferase (ALT) and aspartate aminotransferase (AST) could be observed,which gradually decreased in 3-4 days;the recovery of TB level was slower than that of ALT and AST levels.Two patients had concomitant myocardial damage,which was gradually recovered in 2-3 days.Conclusion For the treatment of HCC associated with MPVTT,portal 125I seed stent implantation plus DEB-TACE is safe and feasible,although its long-term curative effect needs to be further clarified.

Maturation Disparity between Hand-Wrist Bones in a Chinese Sample of Normal Children: An Analysis Based on Automatic BoneXpert and Manual Greulich and Pyle Atlas Assessment

OBJECTIVE: To assess the maturation disparity of hand-wrist bones using the BoneXpert system and Greulich and Pyle (GP) atlas in a sample of normal children from China. MATERIALS AND METHODS: Our study included 229 boys and 168 girls aged 2-14 years. The bones in the hand and wrist were divided into five groups: distal radius and ulna, metacarpals, proximal phalanges, middle phalanges and distal phalanges. Bone age (BA) was assessed separately using the automatic BoneXpert and GP atlas by two raters. Differences in the BA between the most advanced and retarded individual bones and bone groups were analyzed. RESULTS: In 75.8% of children assessed with the BoneXpert and 59.4% of children assessed with the GP atlas, the BA difference between the most advanced and most retarded individual bones exceeded 2.0 years. The BA mean differences between the most advanced and most retarded individual bones were 2.58 and 2.25 years for the BoneXpert and GP atlas methods, respectively. Furthermore, for both methods, the middle phalanges were the most advanced group. The most retarded group was metacarpals for BoneXpert, while metacarpals and the distal radius and ulna were the most retarded groups according to the GP atlas. Overall, the BAs of the proximal and distal phalanges were closer to the chronological ages than those of the other bone groups. CONCLUSION: Obvious and regular maturation disparities are common in normal children. Overall, the BAs of the proximal and distal phalanges are more useful for BA estimation than those of the other bone groups.

Assessment of the responses to neoadjuvant chemotherapy of osteosarcoma by diffusion-weighted MR image: initial results / 中华放射学杂志

Objective To determine the utility of diffusion-weighted magnetic resonance imaging ( MR DWI ) in detecting tumor necrosis with histological correlation after neoacljuvant chemotherapy. Methods Conventional MRI and DWI were obtained from 36 patients with histological proven esteosarcoma. Magnetic resonance examinations were performed in all patients before and after 4 cycles of preoperative neoadjuvant chemotherapy. Apparent diffusion coefficients (ADC) were calculated. The degree of tumor necrosis was assessed using the histological Huvos classification after chemotherapy. T-test was performed for testing changes in ADC value between the 2 groups. P value less than 0. 05 were considered as a statistically significant difference. Results The differences in ADC between viable [ (1.06±0. 30) ×10-3mm2/s ] and necrotic [ (2. 39±0. 44 )×10-3mm2/s] tumor were significant (t= 3. 515,P<0. 05). Changes in ADC value was greater in good responses to neoadjuvant chemotherapy than in poor responses, the ADC value in good responses was increased from (1.18±0. 19)×10-3mm2/s to (2. 27±0. 20)×10-3mm2/s, the corresponding value in poor responses was increased from (1.45± 0.11)×10-3mm2/s to (1.83±0. 16)×10-3mm2/s, There was significant difference in changes of ADC values between good responses and poor responses ( t = 4. 981, P < 0. 01 ). Conclusion Diffusion-weighted MRI permits recognition of tumor necrosis induced by chemotherapy in osteosarcoma. DWI is correlated directly with tumor necrosis. They have potential utility in evaluating the preoperative chemotherapy response in patients with primary osteosarcoma.
