ObjectiveTo investigate the importance of nursing observation and intervention for extrahepatic bile duct stones with gallbladder stones treated by electronic duodenoscopic sphincterotomy (EST) combined with laparoscopic cholecystectomy (LC). MethodsFrom July 2011 to February 2014, 157 patients with extrahepatic bile duct stones with gallbladder stones underwent EST and LC at the same time in our department. Combined with the surgery characteristics, we focused on the close observation and nursing of postoperative complications and drainage tubes for patients' timely recovery. ResultsOne patient with duodenal diverticulum papilla did not complete EST and LC surgery, which was then transformed to LC, bile duct incision and choledochoscopy with T tube drainage. All the remaining 156 patients completed endoscopic retrograde cholangio-pancreatography and LC with a completion rate of 99.36%. Under close observation and careful nursing care, this group of patients did not have duodenum perforation, bile leakage or other complications. No patient died. Seven to thirteen days after hospitalization, all the patients were cured and discharged from the hospital. ConclusionFor patients undergoing EST and LC at the same time, observation and timely intervention are very important in reducing serious complications, improving the quality of surgery, enhancing patients' comfort, and promoting postoperative recovery.
Objective To observe the incidence rate of cardiovascular adverse events and evaluate the safety of dexmedetomidine or midazolan sedation in patients with long-term mechanical ventilation in intensive care unit (ICU). Methods From January 2014 to December 2015, patients admitted to ICU aged ≥18 years with mechanical ventilation time ≥48 hours were randomly divided into dexmetomidine group (group D) and midazolam group (group M). Adverse events such as cardiovascular events during sedation were observed. Results There were 144 cases in group D and 143 cases in group M. Slow heart rate was the prominent manifestation in group D. The incidence of heart rate <50 beats per minute in group D (4.86%) was less than that in group M (6.29%), but there was no statistical difference ( P=0.681). Group D had lower blood pressure (40.28% vs. 72.73%), tachycardia (18.75% vs. 41.96%), arrhythmia (16.67% vs. 34.97%) and 28- day mortality (22.22% vs. 42.66%) than those in group M (P<0.01). No cardiac arrest, sinus arrest, hypertension, hyperglycemia, or hypoglycemia were found in the two groups. Conclusion The long-term sedation of dexmetidine in patients with mechanical ventilation is safe; in cardiovascular adverse events, the 28-day mortality is lower than that of traditional midazolam sedation, and the duration of mechanical ventilation is no longer than that of traditional midazolam sedation, with slightly longer ICU length of stay.
Objective To evaluate the expression and clinical significance of Survivin in the tissues of laryngeal carcinoma using meta-analysis. Methods The case-control studies published in China about the expression and association of clinical pathogenic features of Survivin in the tissues of laryngeal carcinoma were electronically retrieved in CBM (1994 to October 2012), CNKI (1994 to October 2012), VIP (1989 to October 2012) and WanFang Data (1996 to October 2012). The reviewers independently identified the literature according to inclusion and exclusion criteria, extracted data, and assessed the quality of the included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results A total of 25 studies were included, involving 1 333 cases of laryngeal carcinoma and 528 cases of health laryngeal mucosa or polyp of vocal cord. The results of meta-analysis showed that, significant differences were found in groups of laryngeal carcinoma vs. health control, laryngeal carcinoma with vs. without lymphatic metastasis, clinical stages I-II vs. III-IV, cell differentiation G1 vs. G2-G3, T1 and T2 stages vs. T3 and T4 stages, and glottic carcinoma vs. non-glottic carcinoma (Plt;0.05). No significant difference was found in groups of age more than 60 vs. no less than 60, male vs. female, and smoke vs. non-smoke (Pgt;0.05). Conclusion Current domestic evidence shows that Survivin may be associated with the whole course of occurrence, advance and transfer of laryngeal carcinoma, and positively correlated to degree of tumor malignance, which may indicate poor prognosis.
ObjectiveTo observe and analyze the structural characteristics of the optic discs in high myopia (HM) combined with primary open-angle glaucoma (POAG) and the optic disc parameters with diagnostic efficacy. MethodsA cross-sectional study. From August 2020 to March 2021, a total of 114 eyes of 68 patients with POAG, HM and healthy volunteers who were diagnosed by Department of Ophthalmology, The First Affiliated Hospital of Kunming Medical University were included in the study. Among them, 21 POAG patients (39 eyes) were divided into H+P group (9 patients, 18 eyes) and non-H+P group (12 patients, 21 eyes) according to whether or not HM was combined; 26 HM patients (37 eyes) were selected as HM group; 21 healthy volunteers (38 eyes) were selected as normal control group. The subjects included 31 males (51 eyes) and 37 females (63 eyes), whose average age was 36.93±12.60 years old. Diopter, central corneal thickness (CCT) and axial length (AL) were measured. There was no significant difference in age (F=8.333), sex composition ratio (χ2=0.863), and CCT (F=1.425) among the four groups (P>0.05); while, there were significant differences in AL (F=69.956), diopter (F=37.711), visual field index (VFI) (F=43.254) and mean defect (MD) (F=49.793) among the four groups (P<0.01). Enhanced depth imaging using optical coherence tomography was used to obtain the tilt parameters, the disc rim parameters, the lamina cribrosa parameters and the retinal nerve fiber layer (RNFL) thickness. The tilt parameters included optic disc horizontal diameter, optic disc vertical diameter, optic disc ellipse index (horizontal diameter/vertical diameter); the disc rim parameters included Bruch’s membrane opening-minimal rim width (BMO), optic cup area, optic disc area, disc rim area, cup-disc area ratio; the lamina cribrosa parameters included anterior laminar insertion depth (ALID), prelaminar neural tissue (PLNT), and lamina cribrosa thickness. The pairwise comparison between groups were performed by ANOVA test. Pearson correlation analysis was used to analyze the correlation between disc tilt parameters, disc rim parameters, lamina cribrosa parameters and visual field parameters, as well as between disc rim parameters and RNFL thickness. According to receiver operating characteristic (ROC) curve and area under the curve (AUC), the predictive value of those above related factors for HM combined with POAG was evaluated. ResultsTilt parameters: compared with the optic disc horizontal diameter of non-H+P group, those of normal control group, HM group and H+P group were significantly decreased (P<0.05), the ellipse indices of HM group and H+P group were significantly lower than those of normal control group and non-H+P group (P<0.05). The results of correlation analysis showed that the optic disc horizontal and vertical diameters were negatively correlated with MD (r=-0.302, -0.235; P=0.002, 0.017), and negatively correlated with VFI (r=-0.291, -0.246; P=0.003, 0.013). Disc rim parameters: the disc cup area and cup-disc area ratio of non-H+P group and H+P group were significantly larger than those of normal control group and HM group (P<0.05). The disc rim area and the average BMO of HM group, non-H+P group and H+P group were significantly smaller than those of normal control group (P<0.05). The results of correlation analysis showed that the cup-disc area ratio (r=-0.584), the average BMO (r=0.650) had the highest correlation with the average RNFL thickness (P<0.001). The superior, inferior, nasal and temporal BMO were all positively correlated with the corresponding quadrant RNFL thicknesses (r=0.431, 0.656, 0.362, 0.375; P<0.05); the optic disc rim area, the average BMO were positively correlated with MD (r=0.449, 0.618) and VFI (r=0.449, 0.605) (P<0.05), among which the correlation of the average BMO was the highest; the optic cup area and cup-disc area ratio were negatively correlated with MD (r=-0.346,-0.559) and VFI (r=-0.312,-0.548) (P<0.001), among which the correlation of the cup-disc area ratio was the highest. Lamina cribrosa parameters: ALID of non-H+P group and H+P group were significantly deeper than those of normal control group and HM group (P<0.05). LC of non-H+P group and H+P group were significantly thinner than those of normal control group and HM group (P<0.05). The results of correlation analysis showed that ALID was negatively correlated with MD and VFI (r=-0.402, P<0.001), VFI (r=-0.405, P=0.001); LC was positively correlated with MD and VFI (r=0.403, P<0.001), VFI (r=-0.401, P=0.015). Comparison of diagnostic efficiency between various optic disc parameters: the results of ROC analysis showed that the cup-disc area ratio had the highest diagnostic performance (AUC=0.847, P=0.007), the maximum Youden index was 0.563, the sensitivity and specificity were 0.833 and 0.730, respectively, and the best critical value was 0.340. ConclusionsOptic disc tilt is more pronounced in HM combined with POAG; BMO in each quadrant could objectively reflect the disc rim defect of HM combined with POAG; the thinning and the backward shift of the lamina cribrosa were consistent with the aggravation of the visual field defect. Among them, the cup-disc area ratio had better diagnostic performance.

Objective To evaluate the rescue intubation induced by ketamine and midazolam in patients with acute respiratory failure.Methods 81 patients with acute respiratory failure admitted between June 2010 and June 2012 were recruited in the study. They were randomly divided to a MF group to receive 0. 05 mg/kg of midazolam + 1 to 2 μg/kg of fentanyl ( n =41) , and aMK group to received 0. 05 mg/kg of midazolam + 0. 5 to 1 mg/kg of ketamine ( n =40) for rescue intubation. The APACHEⅡ score on initial24 hours after admission in ICU, length of ICU stay, and 28-day mortality were recorded. The differences in arterial blood pressure, heart rate, respiration rate, and blood oxygen saturation before intubation and 10 minutes after intubation were compared. Incidences of hypotension and other adverse events and difficult intubation were also recorded.Results The midazolamdose in the MK group was significantly less than that in the MF group ( P lt; 0. 01) . The blood pressure in both groups decreased. The systolic blood pressure dropped most significantly in the MF group ( P lt;0. 05) . The incidence of hypotension was 41. 5% in the MF group, significantly higher than that in the MK group ( 20. 0% , P lt;0. 05) . The incidence of hypotension had no correlation with midazolamdosage ( P gt;0. 05) . There was no significant difference in adverse events except for the arrhythmia between two groups. The length of ICU stay and 28-day mortality were similar in both groups ( P gt; 0. 05) . The incidence of difficult tracheal intubation was nearly 50% in both groups.Conclusions In patients with respiratory failure, rescue intubation induced by ketamine can reduce the dose of midazolam and reduce the incidence of hypotension without more complications. The optimal dose of ketamine in induced tracheal intubation requires further study.
