Objective To investigate the correlation between the number of CD68+ and CD163+ macrophages infiltration and the clinical characteristics of oral squamous cell carcinoma (OSCC),and to investigate the role and significance of CD163+ and CD68+ macrophages in OSCC.Methods Forty-two cases of OSCC resected by operation and diagnosed by postoperative pathology with intact clinical data in our hospitals during 2013-2016 were selected.Other 12 cases of oral mamaxillofacial normal tissue served as controls.The number of CD68+ and CD163+ macrophages infiltration in OSCC was detected by immunohistochemistry.Its correlation with clinical characteristics was analyzed.Results The number of CD68+ and CD163+ macrophages infiltration in OSCC was significantly higher than that in the control group (P<0.05);the infiltration quantity of CD68+ and CD163+ macrophages in poor differentiation and moderate differentiation was significantly higher than that in high differentiation(P<0.05).The number of CD68+ macrophages in lymph node metastasis was significantly lower than that without lymph node metastasis (P<0.05).The number of CD163+ macrophages in the lymph node metastasis was significantly higher than that of CD68+ (P<0.05).The number of CD68+ and CD163+ macrophages had positive correlation in OSCC (r=0.48,P=0.00).Conclusion Tumor-associated macrophages (TAMs) and M2 macrophages may play an important role in OSCC,TAMs may inhibits lymph node metastasis in OSCC,while M2 marcophages may promote the lymphatic matastasis of OSCC.

The facultative anaerobic and strict anaerobic microorganisms enriched and acclimated during the anaerobic digestion process are crucial for the efficiency of the anaerobic digestion system. Most of the problems encountered during running anaerobic digestion processes could be effectively improved via stimulation of microbial metabolic activity. Benefited from the rapid development of microbiome techniques, deeper insights into the microbial diversity in anaerobic digestion systems, e.g. the microbe-microbe interactions and microbe-environment interactions, have been gained. A complex and intricate metabolic network exists in the anaerobic digestion system of solid organic wastes. However, little is known about these interactions and the underlying mechanisms. This review briefly summarized the representative interactions between microbial communities during anaerobic digestion process discovered to date. In addition, typical issues encountered during the anaerobic digestion of solid organic wastes and how microbes can tackle and alleviate these issues were discussed. Finally, future priorities on microbiome research were proposed based on present contribution of microbiome analysis in anaerobic digestion system.

OBJECTIVETo explore prodromes of chemotherapy-induced vomiting (CIV) and their association with CIV in lung cancer patients.
METHODSThe prodromes of CIV in 250 lung cancer patients were analyzed. Logistic regression was used to determine the symptoms most likely correlated with CIV. One hundred fifty-seven patients received medical interventions. The development of correlative symptoms and occurrence of CIV between the intervention and non-intervention groups was analyzed.
RESULTSAmong the 250 patients with the prodromes of CIV, the incidence rate of CIV was 67.2%. Logistic regression indicated that nausea, constipation, insomnia, hiccups, anorexia, and history of drinking were correlated with CIV (P < 0.05 for all). Among the 20 symptoms observed in this study, the incidence rates of relatively common symptoms were nausea (72.0%), anorexia (68.4%), taste changes (48.8%), constipation (45.6%), abdominal distension (45.6%), stomach distension(40.4%), and insomnia (40.0%). The incidence rats of all symptoms except hiccups before and after intervention had significant difference (P < 0.05 for all). The incidence rates of CIV were 30.0% in the intervention group and 50.6% in the non-intervention group, with a significant difference between the two groups (P = 0.009).
CONCLUSIONSProdromes of CIV are closely related to the occurrence of CIV. Timely intervention for prodromes of CIV can reduce the incidence rate of CIV during chemotherapy in lung cancer patients.

Post-traumatic tetanus is the main type of non-neonatal tetanus. To reduce the incidence and mortality rate of tetanus and guide the primary medical institutions to prevent and control tetanus after trauma, National Immunization Planning Technical Working Group of the Chinese Center for Disease Control and Prevention has compiled this document in the reference with Position Paper by World Health Organization, the latest research progress from home and abroad. The guidelines focus on the basic procedures for the prevention and disposition of post-traumatic tetanus, the application of tetanus vaccines and immune preparation, and the pre-exposure immunization in high-risk populations of trauma.
