Résumé
Induction of cancer cell ferroptosis has been proposed as a potential treatment in several cancer types. Tumor-associated macrophages (TAMs) play a key role in promoting tumor malignant progression and therapy resistance. However, the roles and mechanisms of TAMs in regulating tumor ferroptosis is still unexplored and remains enigmatic. This study shows ferroptosis inducers has shown therapeutic outcomes in cervical cancer in vitro and in vivo. TAMs have been found to suppress cervical cancer cells ferroptosis. Mechanistically, macrophage-derived miRNA-660-5p packaged into exosomes are transported into cancer cells. In cancer cells, miRNA-660-5p attenuates ALOX15 expression to inhibit ferroptosis. Moreover, the upregulation of miRNA-660-5p in macrophages depends on autocrine IL4/IL13-activated STAT6 pathway. Importantly, in clinical cervical cancer cases, ALOX15 is negatively associated with macrophages infiltration, which also raises the possibility that macrophages reduce ALOX15 levels in cervical cancer. Moreover, both univariate and multivariate Cox analyses show ALOX15 expression is independent prognostic factor and positively associated with good prognosis in cervical cancer. Altogether, this study reveals the potential utility of targeting TAMs in ferroptosis-based treatment and ALOX15 as prognosis indicators for cervical cancer.
Résumé
Ubiquitin-conjugating enzymes 2C (UBE2C) is a pivotal component of the ubiquitin proteasome system and participates in the regulation of cell cycle. UBE2C is highly expressed in brain tumor tissues and the expression level of UBE2C is closely related to tumor malignancy and prognoses of these patients, therefore, UBE2C may become a biomarker for detection of brain tumors. We summarize the research progress of UBE2C in the occurrence, development, prognosis and molecular mechanism of brain tumors, in order to provide new points for the clinical prevention and treatment of brain tumors.

Another investigation was carried out by interviews with TCM students, English teachers and experts, TCM teachers and experts. Cognitive misunderstandings of English learning among students with TCM majors occurred, such as low participation of English extracurricular learning, wrong learning motivation, weak awareness of self-learning and international exchange and communication. There were 3 ways for solving cognitive misunderstandings, including that students could improve the correct learning attitude and self-learning awareness and practice, that English and TCM teachers and experts could give students some advice of career development and TCM internationalization, and that TCM universities could reinforce English and bilingual teacher team construction, improve educational environment.
Résumé
Various pathological factors can result in the death of hepatocytes during liver injury. Persistent hepatocyte death initi-ates and aggravates chronic inflammation and fibrosis,ultimately leading to liver cirrhosis and hepatocellular carcinoma. Thus, limiting hepatocyte death is an effective strategy for improving liver injury. Necroptosis is a newly characterized form of cell death,which is highly regulated by signaling pathways and has typical morphological features of necrosis. Increasing evidence indicates that necroptosis plays a key role in drug-induced or im-munological acute liver injuries,and in chronic liver injuries in-cluding alcoholic fatty liver,nonalcoholic fatty liver and liver fi-brosis. This article reviews the recent advances on the hepato-cyte necroptosis in liver injury,providing novel insights into the pathogenesis of liver disease and related therapeutic reagents.

The dialysis method was employed to load adriamycin into the micelles formed by temperature and pH sensitive polyhistidine-co-DL-lactide-co-glycolide-polyethylene glycol poly DL-lactide-co-glycolide-co-histidine (OLH-b-PLGA-b-PEG-b-PLGA-b-OLH). The critical micelle concentration (CMC) of the copolymer was measured with pyrene fluorescent probe method under different temperatures. The entrapment rate and drug-loading rate were determined with dialysis method. The diameter, morphology and surface potential of the copolymer micelles were investigated by corresponding instruments, respectively. The release behavior of adriamycin from copolymer micelles and the pH sensitivity were studied. The CMC of the copolymers ranged from 0.022 4 to 0.001 7 microg x mL(-1). The entrapment rate and drug-loading rate were 92.8% and 15.7%, respectively. The micelles have a mean diameter of (61.7 +/- 13.4) nm, and zeta potential was -9.88 mV. The in vitro adriamycin release rate increased with the pH dropping from 7.4 to 5.0. The results indicated that the CMC of the copolymers decreased as the raising of temperature, drug release behavior from the micelles possessed clearly pH sensitivity, and the copolymers may have a potential in targeted delivery system for anticancer drugs.

<p><b>OBJECTIVE</b>To evaluate the efficacy of kushenin in treating patients with chronic hepatitis C after renal transplantation.</p><p><b>METHODS</b>Fifty-five patients were randomly assigned by lottery to the treatment group (29 cases) and control group (26 cases). The same immunosuppression therapy was given to all patients in both groups. Patients in the treatment group were treated with kushenin 0.6 g once a day, while those in the control group were treated with conventional liver protective agents such as vitamins. The treatment duration of both groups was 3 months. The incidences of serious hepatitis and acute rejection reaction, serum biochemistry parameters including indicators of liver and kidney functions, hepatic fibrosis index, and serum HCV-RNA were compared between the two groups.</p><p><b>RESULTS</b>(1) The incidence of serious hepatitis in the treatment group and the control group was 3.45% (1/29 cases) and 11.54% (3/26 cases), respectively, which was insignificantly different between the two groups (P=0.335). (2) The incidence of acute rejection in the treatment group was 6.90% (2/29 cases) and that in the control group was 7.69% (2/26 cases), showing insignificant difference (P=0.335). (3) The differences in serum alanine aminotransferase (ALT), direct bilirubin (DBIL), hyaluronic acid (HA), propeptide collagen type III (PC III), laminin (LN), collagen type IV (Col IV) levels between the two groups were insignificant before transplantation (P>0.05), while the above-mentioned parameters in the treatment group were significantly lower than those in the control group after transplantation (P<0.05). The difference in serum creatinine (SCr) and endogenous creatinine clearance rate (CCr) between the two groups was insignificant before and after transplantation (P>0.05). (4) The negative conversion rate of HCV-RNA in the treatment group was 31.03% (9/29 cases), significantly higher than the value of 11.54% (3/26 cases) in the control group after transplantation (P<0.05). (5) The levels of serum ALT and DBIL in patients with HCV-RNA converted to negative were significantly lower than those with still-positive HCV-RNA (P<0.05).</p><p><b>CONCLUSIONS</b>Kushenin has a certain effect on inhibiting the proliferation of HCV, protecting liver cells, and anti-liver fibrosis. On the other hand, it has no obvious influence on renal allograft function. Thus, the drug is clinically safe and effective for use in treating patients with chronic hepatitis C after renal transplantation.</p>
