Colorectal cancer (CRC), a malignant tumor worldwide consists of microsatellite instability (MSI) and stable (MSS) phenotypes. Although SHP2 is a hopeful target for cancer therapy, its relationship with innate immunosuppression remains elusive. To address that, single-cell RNA sequencing was performed to explore the role of SHP2 in all cell types of tumor microenvironment (TME) from murine MC38 xenografts. Intratumoral cells were found to be functionally heterogeneous and responded significantly to SHP099, a SHP2 allosteric inhibitor. The malignant evolution of tumor cells was remarkably arrested by SHP099. Mechanistically, STING-TBK1-IRF3-mediated type I interferon signaling was highly activated by SHP099 in infiltrated myeloid cells. Notably, CRC patients with MSS phenotype exhibited greater macrophage infiltration and more potent SHP2 phosphorylation in CD68+ macrophages than MSI-high phenotypes, suggesting the potential role of macrophagic SHP2 in TME. Collectively, our data reveals a mechanism of innate immunosuppression mediated by SHP2, suggesting that SHP2 is a promising target for colon cancer immunotherapy.

To explore the status of the job satisfaction of the authorized and contract staff in a university affiliated hospital in the dilution situation of the hospital staffing management, and to discuss the key factors and reasons affecting the satisfaction difference. The questionnaire was developed based on Minnesota Satisfaction short form with extra items covering “the comprehensive satisfaction evaluation”. According to the hospital population of staff, the cluster random sampling method was used, and survey was conducted on the spot. Both authorized staff and the contract staff showed high degree of satisfaction. But the contract staff showed higher degree of satisfaction of leadership and their own responsibility sense than the authorized staff. The contract female staff showed higher degree of overall satisfaction than the authorized female staff. The discussion based on the results showed that new human resource management mode, new mechanism of flexible management of staff, targeted staff with targeted management.

To explore the patterns and ideas of medical cooperation between Beijing and Hebei Chinese Medicine hospitals under the background of the integration of Beijing-Tianjin-Hebei regions. By searching the 2015 China statistical yearbook for health, a survey was conducted among doctors and patients in a Hebei hospital, which is cooperate with the Beijing hospital. We found that Beijing-Tianjin regional medical resources were imbalanced, and Hebei medical resources were insufficient, and patients and doctors were satisfied with the cooperation. There are still some difficulties in Chinese medicine hospital of Beijing and Tianjin cooperation, and many departments need to work together to promote Beijing-Tianjin-Hebei rational allocation of medical resources.

Objective To find out the general status about the traditional Chinese medicine therapies that were included into medicare among the selected hospitals in the country's public hospital reform project, and to investigate the reasons for those not included and make recommendations.Methods Collecting relevant information through questionnaires, experts interviews and discussions.Results There are still some TCM therapies not included into the range of reimbursement.Most Of them are external treatment of traditional Chinese medicine, acupuncture, massage, special treatments of traditional Chinese medicine and comprehensive therapies of TCM.Conclusions The establishment of negotiations department about medicare in the field of traditional Chinese medicine was needed.Medicare should be in favor of TCM therapies, and traditional Chinese medicine hospitals should strengthen training of personnel and hiring.At the same time, a reasonable increase of the proportion of TCM experts involved in the making health insurance directory was needed.
