Randomized Controlled Trial[Effect of perioperative multi-day low dose ketamine infusion on prevention of postmastectomy pain syndrome].
Objective: To investigate the effects of multi-day low dose ketamine infusion for postmastectomy pain syndrome (PMPS) after breast cancer surgery. Methods: This study was a prospective randomized controlled trial. From June 2015 to May 2016 in Affiliated Yiwu Hospital of Wenzhou Medical University, 66 patients with breast cancer surgery were randomly divided into control group (group C) and ketamine group (group K). ⋯ There were no significant difference in pain level and site between two groups of PMPS patients (all P>0.05). There were no significant difference of HADS scale preoperative and 5 d after surgery between two groups (all P>0.05); and HADS scale in group K at 3 m and 6 m after surgery was significantly lower than that in group C(all P<0.05). Conclusion: Perioperative continuous multi-day low dose ketamine infusion can effectively reduce the incidence of PMPS after breast cancer surgery.

[Efficacy and safety of transbronchial cryobiopsy in the etiologic diagnosis of diffuse lung disease].
Objective: To assess the efficacy and safety of transbronchial cryobiopsy (TBCB) for the etiologic evaluation of diffuse lung disease (DLD). Methods: Between December 2015 to April 2017, a total of 38 patients with DLD met the inclusion criteria for TBCB in the First Affiliated Hospital of Chongqing Medical University, and 35 of them consented to undergo the procedure under rigid or flexible bronchoscopy. On the tissues obtained from the 35 patients, histopathologic and microbiological evaluations were performed, and together with clinical and radiological manifestations, diagnoses were made and the efficacy of TBCB in the diagnosis of DLD was confirmed, and then therapies were planned accordingly. ⋯ Bleeding occurred in all 24 patients who received TBCB under rigid bronchoscopy (11 patients with mild bleeding, 12 moderate and 1 severe) and was controlled after coagulation measures. After one month of treatment according to the diagnoses acquired with cryobiopsy, the condition was cured in 1 patient (3.0%), alleviated in 17 (51.5%), stable in 11 (33.3%), and deteriorated in 4 (12.1%). Conclusion: TBCB yields reliable diagnoses with a good safety profile.

[Dysfunctional resting-state connectivity of default mode network in adolescent patients with first-episode drug-naive major depressive disorder].
Objective: To study resting-state functional connectivity (FC) of default mode network (DMN) in adolescent patients with first-episode drug-naive major depressive disorder (MDD). Methods: We enrolled thirty first-episode and drug-naive adolescent MDD patients and twenty-nine adolescent healthy control (HC) participants in the First Affiliated Hospital of Zhengzhou University. There were no differences in age, sex, and education between the MDD and HC group. ⋯ The reduced FC between the left middle temporal gyrus and left PCC as well as the enhanced FC between the right middle cingulum and right MPFC were positive correlated with the duration of depression since onset (r=0.39, P=0.03; r=0.38, P=0.04). Conclusions: These findings show dysfunctional DMN connectivity of adolescent MDD patients. Neurodevelopmental abnormalities in DMN may present in adolescent MDD.

Randomized Controlled Trial[Study of sevoflurane/remifentanil coadministration on improving emergence and recovery characteristics of patients following general anaesthesia with sevoflurane].
Objective: To investigate the effects of remifentanil infusion on emergence and recovery characteristics of patients with thoracoscopic lobectomy following general anaesthesia with sevoflurane. Methods: One hundred patients, who were aged 37 to 65 years with American Society of Anesthesiologists (ASA) physical status 1-2, and scheduled for elective thoracoscopic lobectomy under general anaesthesia in National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, from February 2016 to August 2016, were allocated to receive sevoflurane maintenance regimen(group S, n=50)or sevoflurane/remifentanil maintenance regimen(group SR, n=50)by random digital table. After routine induction and intubation, anaesthesia was maintained with 2% sevoflurane in group S and 1.5% sevoflurane/remifentanil(continuous intravenous injection at rate of 4 μg·kg(-1)·h(-1))coadministration in group SR respectively, with intermittent intravenous infusion of sulfentanil. ⋯ The difference were statistically significant(χ(2)=20.294, 23.574, all P<0.05). The NRS and incidence of complaining CRBD were similar in both groups(all P>0.05). Conclusion: Compared with sevoflurane maintenence, coadministration of remifentanil and sevoflurane maintenance regimen provides better emergence and recovery which are characterized by faster awakening and extubation with a lower incidence of emergence coughing and agitation.
