A YAP/TAZ-CD54 axis is required for CXCR2-CD44- tumor-specific neutrophils to suppress gastric cancer

As an important part of tumor microenvironment, neutrophils are poorly understood due to their spatiotemporal heterogeneity in tumorigenesis. Here we defined, at single-cell resolution, CD44-CXCR2- neutrophils as tumor-specific neutrophils (tsNeus) in both mouse and human gastric cancer (GC). We uncovered a Hippo regulon in neutrophils with unique YAP signature genes (e.g., ICAM1, CD14, EGR1) distinct from those identified in epithelial and/or cancer cells. Importantly, knockout of YAP/TAZ in neutrophils impaired their differentiation into CD54+ tsNeus and reduced their antitumor activity, leading to accelerated GC progression. Moreover, the relative amounts of CD54+ tsNeus were found to be negatively associated with GC progression and positively associated with patient survival. Interestingly, GC patients receiving neoadjuvant chemotherapy had increased numbers of CD54+ tsNeus. Furthermore, pharmacologically enhancing YAP activity selectively activated neutrophils to suppress refractory GC, with no significant inflammation-related side effects. Thus, our work characterized tumor-specific neutrophils in GC and revealed an essential role of YAP/TAZ-CD54 axis in tsNeus, opening a new possibility to develop neutrophil-based antitumor therapeutics.

Clinical application of adjustable traction skin stretchers in repair of wounds at the lower leg, foot and ankle / 中华创伤骨科杂志

Objective:To evaluate the clinical effects of adjustable traction skin stretchers used in repair of wounds at the lower leg, foot and ankle.Methods:A retrospective study was performed to analyze the clinical data of 56 patients who had been treated for skin defects at the lower leg, foot and ankle from August 2016 to September 2022 at The First Affiliated Hospital of Zhengzhou University, Honghui Hospital, Affiliated to Xi'an Jiaotong University Medical College, The First Affiliated Hospital of Henan Polytechnic University, and Yunnan Zhongde Orthopedic Hospital. There were 35 males and 21 females, aged (39.9±18.7) years. There were 43 traumatic wounds, 3 burns, 6 inflammatory wounds, 3 relief incisions due to osteofascial compartment syndrome, and 1 scar. The areas of skin defect ranged from 2.5 cm × 2.0 cm to 20.0 cm × 10.0 cm. The duration of wounds was (8.6±7.8) d. All the wounds were repaired with adjustable traction skin stretchers. The row-hook type of skin stretchers was used in 28 cases, the single-rod type in 20 cases, the single-rod type combined with an external fixator in 5 cases, and a combination of the row-hook type and the single-rod type in 3 cases.The time for wound traction closure, color of wound skin margin, skin swelling around the wound, functional recovery of affected limb and complications were recorded.Results:The time from skin stretching to wound closure was (7.8±3.8) d in the 56 patients. The color of wound skin edge after stretching was normal in 16 cases, dark red in 38 cases, and dark in 2 cases; the skin swelling around the wound was degree 1 in 21 cases, degree 2 in 33 cases, and degree 3 in 2 cases. The 56 patients were followed up for (8.9±4.1) months. Primary wound closure was achieved in 48 patients, and secondary wound closure in 8 patients after repair with an autologous skin graft. Partial skin necrosis occurred due to tension blisters after skin stretching in 2 patients, one of whom was repaired with an autologous skin graft and the other of whom by dressing change. Deep bone infection recurred in 2 patients whose wounds healed after their bone defects were repaired using Ilizarov technique of bone transfer. In the 56 patients, the muscle strength of the lower extremity beyond the wound was recovered to normal, and the range of motion of the joints adjacent to the wound also recovered to normal.Conclusion:In repair of wounds at the lower leg, foot and ankle, adjustable traction skin stretchers can lead to fine clinical effects and limited complications, because the stretchers can control the tension of skin digitally and precisely.

Changing trends in etiologies of hospitalized patients with liver disease during 2006 -2014 / 中华肝脏病杂志

Objective@#To analyze the changing trends in etiologies of hospitalized patients with liver disease and provide clinical basis for the formulation of medical policy.@*Methods@#Patients who were hospitalized in the Department of Infectious Diseases from 2006 to 2014 were selected as the research subjects. Data of patients with liver diseases were retrospectively analyzed to determine the proportion of main causes of infection, the proportion of different viral infections in viral hepatitis, and the changing trends in proportion of hepatitis B in different age groups. Kruskal-Wallis test was used for statistical analysis.@*Results@#During 9 consecutive years, the overall proportion of inpatients with liver disease decreased continuously, but the number of patients increased. The top five etiologies of liver diseases were viral hepatitis, drug-induced liver disease, autoimmune liver disease, alcoholic and non-alcoholic fatty liver disease. The proportion of viral hepatitis decreased gradually, and the proportion of drug-induced liver disease and autoimmune liver disease increased markedly. Among viral hepatitis patients, hepatitis B, hepatitis C and hepatitis E were in the top three, with hepatitis B stabilized at around 70%, and the proportion of hepatitis C showed an upward trend. The hospitalization time of hepatitis B patients was gradually shortened, the difference was statistically significant (χ 2 = 205.31, P < 0.001), and the hepatitis B patients were mainly distributed in age groups 31-40, 41-50, and 51-60, the total proportion was above 60%. The difference between the different years of the same age group was not evident, but the proportion of hepatitis B patients decreased gradually in the 14-23 –year- old age group, the difference was statistically significant (χ 2 = 19.51, P = 0.01).@*Conclusion@#Liver disease still holds a principal position in the distribution of infectious diseases, and especially the cause of non-infectious liver disease require sufficient attention and concern. The use of hepatitis B vaccine has effectively diminished the infection rate, but the prevention and control of chronic hepatitis B infection is still facing challenges.

Objective To explore the relationship between body mass index (BMI) and frailty among community aged people. Methods A total of 1571 aged people in two communities in Zhengzhou, Henan, China were recruited by convenience sampling method. They were divided into normal group, overweight group and obesity group according to BMI, and were assessed with Fried Frailty Criteria. Results The rates of overweight and obesity were 38.6%and 10.9%, respectively. There was significant difference in the level of frailty among dif-ferent groups (χ2=86.659, P<0.001). Multivariate Logistic regression analysis showed that overweight and obesity were independent risk fac-tors of pre-frailty (P<0.05), and obesity was the independent risk factor of frailty (P<0.05). Conclusion The prevalence of overweight and obesity was higher in community aged people in Zhengzhou, and normal BMI was important to postpone the process of frailty.

Language Functional Changes after Ischemic Stroke / 中国医学科学院学报

Language function after ischemic stroke remains controversial. Lesion location was thought to be the main determinant of aphasia. However,some studies have shown inconsistencies between clinical manifestations and imaging findings,thus challenging the classic anatomy of aphasia. In addition,language reorganization after ischemic stroke is poorly understood,especially the role of the non-dominant hemispheric homologous language area plays in the rehabilitation of aphasia. In this review,by focusing on the localization of language functional area and the role of non-dominant hemispheric homologous language area in the rehabilitation of aphasia,we try to elucidate the functional changes after ischemic stroke and provide theoretical basis for its rehabilitation.
