Objective To compare the clinical efficacy of double-lumen tube intubation between McGrath-5 video-laryngoscope and McCoy laryngoscope in patients with difficult airway. Methods Sixty patients who were predicted as difficult double-lumen tube intubation were divided into two groups using random number table method:McGrath-5 video-laryngoscope group (group A, n = 30) and McCoy laryngoscope group (group B, n = 30). All patients were intubated by two laryngoscopes correspondingly after conventional induction. The success rate of the first intubation, intubation time, the ratio of right positioning, the number of SpO2 < 90% within intubation time, the number of pressing the cricoid, the incidence of intubation complications and hemodynamic parameters [The changes in systolic pressure and heart rate and BIS were recorded before induction (T0), glottic exposure upon laryngoscope insertion (T1), immediately after intubation (T2), 3 min (T3) after intubation]. Results The number of pressing the cricoid was smaller in group A than in group B (P < 0.05), whereas the intubation time in group A was significantly higher than that in group B (P < 0.05). The systolic pressure and heart rate at T3 were dramatically reduced compared with those measured at T0 in both groups (P < 0.05). The systolic pressure and heart rate at T1 and T2 in group A were considerably lower in group A than those in group B (P < 0.05). Conclusions Compared with the McCoy laryngoscope, double-lumen tube intubation by McGrath-5 video-laryngoscope can less impact on hemodynamics, less intubation complications, intubation time although prolonged but not for influence the patient's oxygen supply, for difficult airway double-lumen tube intubation provides a good choice.

Objective To compare the different front plastic angle with reinforced plastic endotracheal tube guidance by McGrath -5 video laryngoscope for orotracheal intubation in obesity.Methods 1 20 cases with obesity undergoing general anesthesia,ASA gradeⅠ -Ⅲ who planned intubation guidance by McGrath -5 video laryngo-scope,were randomly divided into three group according to different front plastic angle for endotracheal tube:group A (catheter 60°),group B(catheter 75°),C group(catheter 90°),40 cases in each group.General information and air-way evaluation indexes such as Mallampati classification,the degree of open mouth,neck circumference,thyromental distance,atlanto -occipital joint stretch degree preoperatively were recorded.C /L classification with laryngoscopic exposure,the successful rate of first intubation,time of first intubation,cases of second intubation,the incidence of blood stained catheter and postoperative sore throat and hoarseness were recorded also.Results There were no signif-icant differences of patients with general information and airway evaluating indexes such as Mallampati classification, the degree of open mouth,neck circumference,thyromental distance,atlanto -occipital joint stretch degree among three groups(P >0.05).The successful rate of catheter alignment glottal was 97.5% in group B,which was signifi-cantly higher than that of group A(80.0%)and group C(85.0%)(χ2 =8.36,P <0.05).The time of first intuba-tion was 21 (1 0 -65)s in group B,which was significantly shorter than that in group A[30(1 4 -78)s,Z =3.87,P <0.05]and group C[32(9 -80)s,Z =4.32,P <0.05].All patients in three groups had successful intubation firstly or secondly.The incidence rate of blood stained catheter in group B(2.5%)was significantly lower than that in group A(1 0%)and group C(1 5%,P <0.05 ),but there was no significant difference in postoperative sore throat and hoarseness among three groups(P >0.05).Conclusion McGrath -5 video laryngoscope which guided endotracheal tube with front plastic angle at 75°degree has highest success rate of intubation,shortest intubation time,least compli-cation and is suitable for the application of tracheal intubation in obese patients.

Objective To compare the clinical efficacy,adverse reactions,and management effect of postoperative intravenous analgesia for patients with postoperative intravenous analgesia with digital information technology and electronic analgesia pump system.Methods Totally 100 patients with postoperative intravenous analgesia (PCIA) were selected from April 2015 to September 2015 with postoperative intravenous analgesia and randomly divided into Wireless analgesic pump system Group (A group) and electronic analgesia pump group (group B),n =50 each group.Pain score (NRS),sedation score (OAA/S),comfort score (BCS),the total number of times and the number of effective press were pressed in patients were observed and compared between two groups after postoperative analgesia 1 hour (T0),4 hour (T1),10 hour (T2),16 hour (T3),and 24 hour (T4).Patients with early adverse reactions,patients and ward medical staff satisfaction,pain pump failure found in the medical staff and effective treatment of adverse events were also observed and compared in two groups.Results There were no significant difference of patients with NRS,OAA/S and BCS in two groups (P ＞ 0.05).Adverse reactions after postoperative analgesia,total number of times and the number of effective press had also no significant difference in two groups (P ＞ 0.05).Two groups of patients with air blockage,incomplete analgesia rate of adverse events was not significantly different (P ＞ 0.05).Medical workers in time [(1.0 ± 0.5) min vs (3.0 ± 2.1) min,P ＜ 0.05],effective processing time [(4.0-± 2.1) min vs (8.0 ± 5.1) min,P ＜ 0.05] in group A was significantly shorter than group B.The patient satisfaction in group A was significantly higher than group B(12.0 ± 4.2 vs 9.0 ± 3.1,P ＜ 0.05).The satisfaction degree of medical staff in group A was also significantly higher than group B(13.0 ±3.1 vs 10.0 ±2.1,P ＜0.05).Conclusions The digital information technology of wireless analgesic pump is applied to postoperative analgesia for medical workers to standardize management,improve the work efficiency,and increase the satisfaction of patients and medical staffs.

Objective: To explore the related factors of subependymal hemorrhage (SEH) and cerebral hemodynamic changes. Methods: From October 2012 to October 2017, 200 cases of children with subependymal hemorrhage diagnosed by ultrasound in our department of pediatrics were selected as the observation group , and a total of 150 children who were admitted to the Department of Pediatrics in the same period due to craniocerebral diseases and other serious diseases were selected as control group. The independent risk factors of the children in the observation group were analyzed, and the difference of the maximum systolic blood flow velocity (SV), the diastolic maximum flow velocity (DV), the systolic and diastolic velocity ratio (S/D), the resistance index (RI), and the pulsatile index (PI) were compared between the two groups. Results: Neonatal asphyxia, preterm birth, acidosis, neonatal respiratory distress syndrome (NRDS), patent ductus arteriosus and coagulation dysfunction were independent risk factors for subependymal hemorrhage. The bleeding side SV and DV of the observation group were higher than those of the control group, with statistically significant difference (P<0.001). In the observation group, the bleeding side SV and DV were higher than those of the healthy side, with statistically significant difference (P<0.001). There was no significant difference in bleeding side SV, DV, S/D, RI and PI in 110 cases of single side ependymal hemorrhage (P>0.05). Conclusions Children with ependymal hemorrhage can observe the hemodynamic indexes of anterior cerebral artery (ACA) dynamically by craniocerebral ultrasound, and judge the therapeutic effect by evaluating the systolic and diastolic blood flow velocity, so as to prevent the further aggravation of subependymal hemorrhage

OBJECTIVE: To investigate the relationship between airborne allergen and patients with nasal polyps (NP). METHOD: Eighty-three cases of patients with NP were classified into the eosinophilic group(ENP) and non eosinophilic group (nENP) in terms of the EOS count in NP specimen, all patients underwent specific-IgE test with standardized allergens and the results were analyzed. RESULT: The specific-IgE positive rate was 59.26% in ENP group and 23.21% in the nENP group respectively (P < 0.01), and the positive rate of ENP was statistical significance compared with nENP. The dust mite was the most prevalent airborne allergen in ENP group. CONCLUSION The perennial airborne allergens may play a certain role in the etiology and pathogenesis of NP.

Objective To investigate the clinical significance of serum and urinary levels of neutrophil gelatinase-associated lipocalin (NGAL ) for evaluating changes of residual renal function after living donor kidney resection under different operation model in young versus elderly patients. Methods The clinical data of renal transplants were retrospectively analyzed by successfully using 66 living-related donors at the First Affiliated Hospital of Zhengzhou University from September 2016 to October 2017. According to the operation model and age ,renal donors were divided into 4 groups :group A (young/open) ,group B (young/laparoscopic) ,group C (aged/open) ,and group D (aged/laparoscopic).Blood and urinary NGAL and serum levels of creatinine ,cystatin C ,and other indices of renal function were assayed and collected before and at 1 ,3 ,7 days after operation. Results Both blood NGAL levels and urinary NGAL levels showed no statistically significant difference (all P>0.05) among four groups both before and after operation ,except that urinary NGAL was higher in group C (aged/open) than other groups ,at 1 day after operation ,(P = 0.03).The post-vs.pre-operation level dynamic changes of renal function were four or three times higher in urine or serum NGAL level than in serum creatinine or cystatin C level at 1 day after operation ,which showed an important role for predicting an early residual renal damage and relative treatment. Conclusions NGAL can be used as indices in evaluating changes of residual renal function after living donor kidney resection ,especially in the elderly receiving open kidney resection.

IL-34 can promote osteoclast differentiation and activation, which may contribute to steroidinduced osteonecrosis of the femoral head (ONFH). Animal model was constructed in both BALB/c and IL-34 deficient mice to detect the relative expression of inflammation cytokines. Micro-CT was utilized to reveal the internal structure. In vitro differentiated osteoclast was induced by culturing bone marrow-derived macrophages with IL-34 conditioned medium or M-CSF. The relative expression of pro-inflammation cytokines, osteoclast marker genes, and relevant pathways molecules was detected with quantitative real-time RT-PCR, ELISA, and Western blot. Up-regulated IL-34 expression could be detected in the serum of ONFH patients and femoral heads of ONFH mice. IL-34 deficient mice showed the resistance to ONFH induction with the up-regulated trabecular number, trabecular thickness, bone value fraction, and down-regulated trabecular separation. On the other hand, inflammatory cytokines, such as TNF-α, IFN-γ, IL-6, IL-12, IL-2, and IL-17A, showed diminished expression in IL-34 deficient ONFH induced mice. IL-34 alone or works in coordination with M-CSF to promote osteoclastogenesis and activate ERK, STAT3, and non-canonical NF-κB pathways. These data demonstrate that IL-34 can promote the differentiation of osteoclast through ERK, STAT3, and non-canonical NF-κB pathways to aggravate steroid-induced ONFH, and IL-34 can be considered as a treatment target.

Objective To provide scientific evidence to identify and confirm severe acute respiratory syndrome (SARS) by laboratory detection.Methods Multiple clinical specimens were collected serially and systematically from the 4 suspected SARS patients, which occurred between Dec.2003 to Jan.2004 in Guangdong Province. The samples were tested by serologic and molecular methods.Results IgM or IgG antibodies against SARS-CoV were detectable after 6—8 days of the onset in four patients. The four-fold or greater rising in antibodies was clearly detected in three of the four patients, while the fourth patient’s seroconversion was from negative to positive. The results analysed by enzyme-linked immunosorbent assay( ELISA), immunoflourescence assay (IFA), and neutralization test were highly correlated. SARS-CoV RNA was just detected in 3 throat swab specimens from case 1 by real-time PCR. M, N and S genes were amplified by reverse transcriptase polymerase chain reaction (RT-PCR) from the positive samples. Sequencing results showed that they were SARS-CoV gene segments, and most closely matched SARS-CoV gene sequences were isolated from civet cats in Guangdong Province. Nevertheless, SARS-CoV was not isolated from any samples of the 4 patients.Conclusion Based on these results, the 4 reported cases were laboratorily confirmed as SARS cases.
