ObjectiveTo compare the effects of dexmedetomidine and propofol for stereotactic brain surgery in patients with intractable psychosis.MethodsThirty male patients with intractable psychosis,aged 22-33 yr,weighing 60-90 kg,scheduled for stereotactic surgery,were randomized to receive either propofol (group P,n =15) or dexmedetomidine (group D,n =15).Anesthesia was induced with iv injection of midazolam 0.05-0.10 mg/kg and fentany 1-2 μg/kg in the two groups,and in addition,dexmedetomidine was infused at 0.3-0.7μg· kg- 1 · h- 1 after a loading dose of 1 μg/kg (duration of infusion ＞ 10 min) and propofol 1-2 mg/kg was injected intravenously before endotracheal intubation in group D and propofol 2-3 mg/kg was injected intravenously and then propofol was infused at a rate of 3-4 mg· kg- 1 · h- 1 in group P.Orotracheal intubation was performed under the guidance of direct laryngoscope.The patients kept spontaneous breathing.The adverse events such as body movement,bucking,apnea,adverse cardiac events and hypoxemia were recorded during location.ResultsThe incidence of body movement,bucking,apnea,tachycardia,hypotension and hypoxemia was significandy lower,while the incidence of bradycardia was significantly higher in group D than in group P ( P ＜ 0.01 ).There was no significant difference in the incidence of hypertension between the two groups (P ＞ 0.05).ConclusionDexmedetomidine provides better anesthesia,exerts less effect on the respiratory and circulatory functions and is safer than propofol for stereotactic surgery in patients with intractable psychosis.

OBJECTIVETo investigate the value of C-reactive protein (CRP) on transplantation day in predicting early post-transplant infections and outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSWe retrospectively analyzed the clinical data of 78 recipients undergoing allo-HSCT. The clinical reference value of CRP on transplantation day was determined, and its sensitivity and specificity for diagnosing bacteremia was analyzed using receiver-operating characteristic curve (ROC). The incidence of transplant-related complications, overall survival, and relapse rate of the patients were analyzed with respect to the CRP level.

RESULTSThe clinical reference value of CRP for diagnosing bacteremia was 23.3 mg/L (AUC=0.735 [95% CI: 0.623-0.848], P=0.001), which had a diagnostic sensitivity and specificity of 0.793 and 0.592, respectively. Compared with the patients with low CRP levels, the patients with high CRP levels tended to have delayed neutrophil reconstitution and platelet engraftment by 0.71 days (P=0.237) and 4.09 days (P=0.048), respectively, and had a significantly higher incidence of bacteremia (17.1% vs 53.5%, P=0.001) and CMV viremia (37.1% vs 72.1%, P=0.003) within 100 days following the transplantation; the incidences of EBV viremia, pulmonary invasive fungal infection, or acute graft versus host disease (aGVHD) showed no significant difference between the two groups (41.9% vs 22.9%, P=0.094; 14.0% vs 5.7%, P=0.285; 51.2% vs 45.7, P=0.656, respectively). During the follow-up for a median of 318 (7-773) days in high-CRP group and for 299 (78-747) days in low-CRP group, the high-CRP group showed a significantly lower 2-year overall survival than the low-CRP group (42.5% vs 78.4%, P=0.022), and tended to have a higher 2-year cumulative relapse rate (52.3% vs 19.8%, P=0.235). Logistic multivariate analysis identified a high CRP level on transplantation day as the independent risk factor for post-transplant bacteremia within 100 days (OR=5.090 [95% CI: 1.115 -23.229], P=0.036).

CONCLUSIONA high CRP level on transplantation day can be indicative of a high risk of early post-transplant bacteremia and CMV viremia and also a poor prognosis following allo-HSCT.

Objective:To summarize the experience of surgical methods without repairing the fistula for 92 cases with gastrointestinal intrathoracic fistula.Methods:The surgical methods without repairing the fistula were performed through VATS, small incision assisted with VATS or thoracotomy. The focus of the surgery was to promote lung expansion, eliminate the residual cavity of chest cavity and keep effective drainage. After entering the chest cavity from the affected side, wash chest cavity with a large amount of warm normal saline and sterilize intermittently with iodophor to ensure the sterile environment in the pus cavity. Then completely remove the pleural cellulose or fiberboard on visceral pleura to promote lung expansion, eliminate the residual cavity of the chest cavity. The fistula was covered tightly and supported firmly by the visceral pleura on the lung. Multiple T-tubes were placed in thoracic cavity and fistula to keep effective postoperative drainage.Results:Among 92 cases, 85 cases were cured and the cure rate was 92.4% (85/92).7 cases died and the mortality rate was 7.61% (7/92). The 7 dead cases include 5 cases with esophagogastric anastomotic fistula (the death of 3 cases was cause by aortic esophagogastric fistula, the death of 1 case was cause by thoracic gastric tracheal fistula and 1 case was dead because of pulmonary infection and respiratory failure), 1 case with esophageal rupture (the cause of death was septic shock ), and 1 case with esophageal perforation(the cause of death was pulmonary infection and respiratory failure).Conclusion:Most of the surgeries without repairing gastrointestinal intrathoracic fistula are conducted simply through VATS or small incision assisted with VATS., which is safe and effective.

Objective:To investigate the drug-resistant gene characteristics and core genome characteristics of carbapenem-resistant Enterobacter cloacae (CR-ECL) in rural residents of Weifang City, Shandong Province. Methods:Fecal samples were collected from rural community residents in Weifang City, Shandong Province in 2017. Drug-resistant strains were screened using a carbapenem-resistant enterobacter chromogenic medium. CR-ECL positive strains were acquired via Matrix Assisted Laser Desorption Ionization Time of Flight Mass Spectrometry(MALDI-TOFMS) analysis. The antibiotic resistance phenotype of CR-ECL was determined using a microbroth dilution assay. Whole genome sequencing (WGS) and analysis were conducted, along with an examination of the immediate vicinity of the blaNDM gene and phylogenetic analysis of the strains. Results:A total of 628 fecal samples were collected and tested, of which 6 were CR-ECL positive (detection rate 0.96%), all exhibiting multiple drug resistance (MDR) phenotypes. Six CR-ECL strains had four MLST genotypes (ST), all of which carried multiple drug resistance genes ( blaNDM-1, blaNDM-5, etc.) and virulence genes ( acrA, acrB, entB, fepC, etc.). There were mobile genetic elements ISAba125, TN3-IS3000, TN3 and IS5 in the genetic environment surrounding the blaNDM gene. The phylogenetic tree showed that the multi-locus sequence typing of the core genome (cgMLST) was consistent with the single nucleotide polymorphism (SNPs) results. The cgMLST results showed that the allele differences between strains 2BC0101B and 2BC0251B, 2BG0561B and 2BI0221B were 2 and 1, respectively. The SNPs results showed that the above two pairs of bacteria also clustered together. It was found that the strains of chicken fecal samples in the National Center for Biotechnology Information (NCBI) database were located in the center of the evolutionary tree, and the local sequences could be traced back to American human sequences. Conclusion:Multidrug-resistant CR-ECL is detected in rural community residents in Weifang City, Shandong Province.

BACKGROUND: Previous studies have shown that the neutrophil-to-lymphocyte ratio (NLR) has a significant impact on the prognosis of many malignant tumors such as gastric cancer, colorectal cancer and pancreatic cancer, but the study on the prognosis of patients with resectable lung adenocarcinoma is less. The aim of this study is to investigate the correlation between the NLR and the clinicopathologic features of adenocarcinoma of lung patients who underwent radical pneumonectomy. Furthermore, this study aimed to clarify the predictive and prognostic significance of NLR in patients who underwent pneumonectomy for lung adenocarcinoma. METHODS: This study reviewed the medical records of 163 patients with lung adenocarcinoma who underwent pneumonectomy. The receiver operating characteristic (ROC) curve and Youden index were used to determine the cut-off value of the NLR. Survival curves were described by Kaplan-Meier method and compared by Log-rank test. The univariate and multivariate analyses were performed with the Cox proportional hazard model to identify the prognostic factors. RESULTS: When the NLR value was 2.96, the Youden index was maximal, with a sensitivity of 77.5% and a specificity of 75.9%. The 5-year survival rate in the low NLR group was higher than that in the high NLR group (P<0.05). The univariate and multivariate analyses showed that TNM staging and NLR were independent factors in predicting survival rate. CONCLUSIONS The NLR value was a simple and useful tool to predict the prognosis of lung adenocarcinoma after radical pneumonectomy.

BACKGROUND: Currently, there are many reports on the advantages of three portal video-assisted thoracic surgery (VATS) in the treatment of lung cancer, but there are few reports on the comparison between uniportal and three portal video-assisted thoracic surgery. In this study, we aimed to evaluate the recent curative effect of the postoperative short-term quality of life between uniportal and three portal video-assisted thoracic surgery for non-small cell lung cancer. METHODS: We retrospectively evaluated 266 patients with NSCLC who underwent intended VATS lobectomy by a single surgical team in our ward between January 2016 and August 2017. The general clinical date, perioperative data and short-term life quality were individually compared and analyzed between the two groups. RESULTS: The two groups were similar in terms of clinicopathological features, total number of dissected lymph nodes and nodal stations, postoperative complications and pulmonary complications (P>0.05). Compared with three portal VATS, the intraoperative blood loss, chest tube duration, postoperative thoracic drainage, length of stay and NRS score were significantly decreased in uniportal VATS, with significant differences (P<0.05). CONCLUSIONS As a more minimally invasive surgery, uniportal VATS can be safely and effectively performed for resectable lung cancer, which would achieve even better operation curative effect than three portal VATS.
