A large number of cancer-associated fibroblasts (CAFs) in tumor tissues create a favorable environment for the development of tumor. CAFs inhibit immune cells activation and viability by cytokine secretion, and CAFs prohibit drugs and immune cells infiltration by producing extracellular matrix to weaken cancer treatment efficacy. Regulating CAFs or overcoming CAFs barriers are new strategies for cancer therapy. Hence, designing nano-carriers for regulating CAFs to suppress tumor progression or promoting drug delivery to tumor site by overcoming CAFs barriers has attracted much attention. Therefore, this manuscript reviewed the recent progresses of nano-carriers for CAFs-targeting cancer therapies, in order to provide a reference for clinical cancer treatment.

Objective To investigate the molecular mechanisms for the development of cardiac hypertrophy in hypertension,the present study provided the differential protein expression analysis of hypertrophied heart at differ- ent stages in spontaneously hypertensive rats (SHR).Methods The profiles of protein expression of left ventricu lar myocardium in SHR and its normotensive control Wistar-Kyoto (WKY) rats at the age of 4 and 20 weeks were analyzed with two-dimensional gel electrophoresis (2-DE) in combination with matrix assisted laser desorption ioniza- tion-time of flight (MALDI-TOF-TOF) mass spectrometry.Results Although the blood pressure of SHR was normal at 4 weeks age,hypertrophy of the left ventricle had already developed.The expression pattern in the hy- pertrophic myocardium was found 27 modulated proteins,20 of which were identified.These proteins are involved in reactions of energy metabolism,mitoehondrial oxidative phosphorylation and oxidative stress,etc.The expres- sion of 13 proteins was significantly changed in SHR rats at early stage prior to the development of sustained hyper- tension,while the expression changes of other 7 proteins occurred only at late stage in SHR rats when the blood pressure was significantly elevated.Conclusions lncrease in glycolysis and decrease in oxidation of fatty acid and glucose was shown in the hypertrophied myocardium from early stage in SHR prior to the development of hyperten sion.The significant changes in protein expression of the mitochondrial electron transport chain and antioxidative molecules support the hypothesis that oxidative stress promotes and accelerates the development of hypertensive car- diac hypertrophy.

Objective To improve the selection of flying cadets of the Air Force of People′s Liberation Army of China ( PLAAF) by analyzing the differences of medical identification of lumbar spondylolysis between PLAAF and the US Air Force ( USAF) .Methods Flight crew who had been checked for lumbar spondylolysis during hospitalization at the Air Force General Hospital between 2013 and 2015 were chosen.The results of their medical identification were compaired according to PLAAF and USAF Medical Standards Directory, and their differences and possible reasons were analyzed accordingly.Results The qualified rate of PLAAF was about 85%, which was very close to the standards of USAF, but the difference was not of any statistical significance(P>0.05).Conclusion The standards of our medical identification of lumbar spondylolysis was similar to those of USAF, suggesting that the selection of flying cadets can be improved.

Objective To explore the efficacy and safety of ticagrelor plus cilostazol of different dosage in the treatment of low-weight patients after PCI.Methods A total of 148 consecutive ACS patients (body weight ≤ 65 kg) past PCI and with aspirin intolerance were enrolled and randomly divided into four groups.Patients given cilostazol 50mg twice daily plus clopidogrel 75 mg daily were named as the CC50 mg group.Patients in the CC100 mg group were given cilostazol 100 mg twice daily plus clopidogrel 75 mg daily.The TCS0 mg group were given cilostazol 50 mg twice daily plus standard ticagrelor 90mg twice daily and the TC100 mg group were given cilostazol 50 mg twice daily plus standard ticagrelor 90 mg twice daily.All patients were followed up clinically for 6 months.The clinical endpoints were MACEs and bleeding events.Platelet aggregation at 7 and 30 days after treatment the incidence of clinical endpoints during followup were compared between the four groups.Results Patients in the TC100mg group had the lowest platelet aggregation rates tested on both the 7th and 30th day after treatment among all the 4 groups.After 6 months of follow up,the MACEs rate was not significantly different between the four groups (P =0.930).Bleeding events rates in the TC100 mg group the highest among the 4 but without groups significant differences.Conclusions In ACS patients with low body weight ≤ 65 kg) past PCI and with aspirin intolerance,cilostazol 50mg twice daily plus ticagrelor is a safe and efficacious therapeutic regimen.

The Infectious hypodermal and hematopoietic necrosis virus (IHHNV) and Taura syndrome virus (TSV) are two important shrimp viruses in cultured shrimp in America. These two viruses were transmitted to China at the beginning of the 21st century. In this study, 214 shrimp samples of Penaeus vannamei were collected from seven different areas of China and tested by PCR for IHHNV and TSV infection. The results showed that there were a high prevalence of IHHNV (65.42%) and low prevalence of TSV (3.27%) in the tested samples. Several samples were found to be co-infected with these two viruses. A 3 kb fragment of 7 positive IHHNV samples and a structure protein region (ORF2) of three TSV positive samples were amplified and sequenced. The sequence comparison indicated that both IHHNV and TSV sequenced in China have a low genetic variations compared with the prototype IHHNV and TSV from Hawaii. Phylogenetic analysis showed that TSV isolates were clustered into two groups, Asia and America group, which was genetically correlated to geographic distribution.
