Expert consensus on marsupialization of cystic lesions of the jaw / 口腔疾病防治

@#Marsupialization is effective in the treatment of cystic lesions of the jaw. It is a simple operation that can result in minimal trauma, the reduction of postoperative recurrence, and maximum preservation of the surrounding tissue structure and function. However, there is a certain failure rate in clinical treatment due to the improper grasp of indications and nonstandard operation. The highest failure rate reported in the literature is 32.6%. To further standardize the clinical application of marsupialization and improve the success rate of treatment, we put forward an expert consensus of marsupialization in the treatment of jaw cystic lesions by reviewing the domestic and foreign literature and summarizing the experience in marsupialization from some famous domestic experts. In this consensus, we propose three elements of marsupialization: the establishment of the opening, the maintenance of cyst plugs and regular washing. The scope of application of marsupialization includes jaw cysts and cystic ameloblastomas. It is necessary to standardize the position of the opening, the size of the opening and the manufacture of the cyst plug, and a panoramic film or cone beam computed tomography(CBCT) should be used to observe the changes in the cystic cavity before and after operation. A second-stage operation should be performed when the lesion is significantly reduced by more than 50% or at least 5 mm from important structures; furthermore, the teeth of focus should be treated according to the relationship between the lesion and tooth and the type of tooth.

Analysis of risk factors of cervical anastomotic leakage after esophageal cancer operation / 中国胸心血管外科临床杂志

@#Objective    To analyze the risk factors of anastomotic leakage after esophagectomy. Methods    The clinical data of 1 328 patients with esophageal cancer, who underwent esophagectomy in the First Affiliated Hospital of Henan University of Science and Technology from January 2010 to December 2016, were retrospectively analyzed. There were 726 males and 602 females, at an average age of 67.2±14.1 years. According to whether there was anastomotic leakage after operation, patients were divided into two groups: an anastomotic leakage group (167 patients) and a non-anastomotic leakage group (1 161 patients). Univariate and multivariate logistic regression analysis was used to identify related risk factors of anastomotic leakage after operation. Results     The incidence of postoperative anastomotic leakage was 12.6% (167/1 328). Univariate analysis showed that body mass index, arrhythmia, chronic obstructive pulmonary disease (COPD), diabetes, preoperative albumin level, preoperative chemotherapy and chemoradiotherapy, lesion location, anastomosis types and postoperative pulmonary infection were associated with statistically significant increase in risk of cervical anastomotic leakage (P<0.05). Logistic regression analysis showed that preoperative COPD, lesion location and postoperative pulmonary infection were independent risk factors of cervical anastomotic leakage after esophagectomy (P<0.05). Conclusion    The occurrence of cervical anastomotic leakage after esophageal cancer is related to many factors. The preoperative COPD, the lesion location and the postoperative pulmonary infection are independent high risk factors. Paying attention to these factors and doing perioperative management can effectively reduce the occurrence of anastomotic leakage.

NBP promotes angiogenesis of HUVECs by activating VEGF/VEGFR2-Notch1/Dll4 signal pathway / 中国病理生理杂志

AIM:To investigate the effects of DL-3-n-butylphthalidle (NBP) on angiogenesis of human um-bilical vein endothelial cells ( HUVECs) and the role of vascular endothelial growth factor ( VEGF)/VEGF receptor 2 (VEGFR2)-Notch1/Delta-like ligand 4 (Dll4) signaling pathway in this process. METHODS:The serum-free medium and anoxic tank were used to simulate the conditions of hypoxia and ischemia ( H/I). HUVECs were divided into control group, H/I group, H/I+NBPhigh group and H/I+NBPlow group. The HUVECs in control group were conventionally cul-tured, and those in H/I group were cultured under H/I intervention. The HUVECs in H/I+NBPhigh group were treated with NBP at 20 μmol/L under H/I intervention. The HUVECs in H/I+NBPlow group were treated with NBP at 5 μmol/L under H/I intervention. The cell viability of each group was measured by CCK-8 assay. The migration ability of the HUVECs in each group was detected by cell scratch test. The vessel formation ability of the HUVECs was examined by in vitro angiogenesis assay. The expression of VEGFR2, Notch1 and Dll4 at mRNA and protein levels was determined by qPCR and Western blot, and the expression of VEGF was determined by qPCR and ELISA. RESULTS:NBP increased the viability of HUVECs, and promoted the migration ability and the formation of blood vessels in vitro under H/I interven-tion. These effects of NBP at high dose were more significant than those at low dose. NBP increased the expression of VEGF, VEGFR2, Notch1 and Dll4 at mRNA and protein levels (P<0.05). CONCLUSION:NBP promotes HUVECs to form blood vessels under H/I intervention. The mechanism may be related to the activation of VEGF/VEGFR2-Notch1/Dll4 signaling pathway.

Aplicação do monitor Narcotrend® para avaliar a profundidade da anestesia em crianças submetidas à cirurgia cardíaca: estudo prospectivo e controlado / Application of Narcotrend® monitor for evaluation of depth of anesthesia in infants undergoing cardiac surgery: a prospective control study / Aplicación del monitor Narcotrend® para evaluar la profundidad de la anestesia en niños sometidos a la cirugía cardíaca: estudio prospectivo y controlado

JUSTIFICATIVA E OBJETIVOS: Investigar a eficácia clínica, segurança e viabilidade do monitor Narcotrend® para avaliar a profundidade da anestesia em crianças com doença cardíaca congênita (DCC) submetidas à cirurgia cardíaca. MÉTODOS: Foram randomicamente selecionadas 80 crianças submetidas à anestesia geral em cirurgia seletiva. As crianças foram divididas em dois grupos de forma aleatória (n = 40 por grupo). No grupo Narcotrend, a profundidade da anestesia foi monitorada com o Narcotrend. No grupo padrão, a profundidade da anestesia foi controlada de acordo com a experiência clínica. A pressão arterial média (PAM) e a frequência cardíaca (FC) foram determinadas e a dose de fentanil e relaxante muscular e os tempos de recuperação e de extubação foram registrados. RESULTADOS: Em ambos os grupos, os sinais vitais apresentaram-se estáveis durante a cirurgia. No grupo Narcotrend, a PAM e a FC foram mais estáveis, a dose total de fentanil e relaxante muscular significativamente menor e os tempos de recuperação e extubação acentuadamente mais reduzidos em comparação com o grupo padrão. CONCLUSÃO: A aplicação do monitor Narcotrend para medir a profundidade da anestesia foi útil para controlar a profundidade da anestesia em crianças com DCC que receberam anestesia intravenosa total, na qual uma pequena quantidade de narcóticos pode obter a anestesia ideal. Além disso, os tempos de recuperação e extubação foram menores e os efeitos secundários, como sensibilização intraoperatória, puderam ser evitados.

BACKGROUND AND OBJECTIVES: To investigate the clinic effectiveness, safety and feasibility of Narcotrend® monitor for evaluation of depth of anesthesia in congenital heart disease (CHD) infants undergoing cardiac surgery. METHODS: A total of 80 infants receiving general anesthesia in selective surgery were randomly selected. Infants were assigned into two groups (n = 40 per group). In the Narcotrend group, the depth of anesthesia was monitored with the Narcotrend monitor. In the standard group, the depth of anesthesia was controlled according to the experience. The mean arterial pressure (MAP) and heart rate (HR) were determined, as well as the dose of fentanyl, muscle relaxant, recovery time and extubation time were recorded. RESULTS: In both groups, vital signs were stable during the surgery. When compared with the standard group, the MAP and HR were more stable, the total dose of fentanyl and muscle relaxant were significantly reduced and the recovery time and extubation time were markedly shortened in the Narcotrend group. CONCLUSION: The application of Narcotrend monitor was beneficial to the control of the depth of anesthesia in CHD infants receiving total intravenous anesthesia, in which small amount of narcotics can achieve optimal anesthesia. Moreover, the recovery time and extubation time are reduced and the harmful consequence such as intraoperative awareness can be avoided.
