Objective: To investigate the predictive value of glycosylated hemoglobin A1c/apolipoprotein A-1 (HbA1c/ApoA-1) ratio for major adverse cardiovascular events (MACEs) in patients with acute coronary syndrome (ACS). Methods: The present study is a retrospective cohort study. ACS patients who were hospitalized and underwent coronary angiography at Beijing Hospital from March 2017 to March 2019 were enrolled. Baseline information such as sex, age, previous history, Gensini score, HbA1c and ApoA-1 were analyzed. Patients were divided into two groups according to presence or absence of MACEs and the difference on HbA1c/ApoA-1 ratio was compared between the two groups. According to the tertiles of HbA1c/ApoA-1 levels, patients were divided into high (5.87-16.12), medium (4.50-5.83) and low (2.11-4.48) HbA1c/ApoA-1 groups. Cox proportional risk model was used to evaluate the differences in MACEs and all-cause mortality among the three groups. Kaplan-Meier survival analysis was used to compare the differences of MACEs between the various HbA1c/ApoA-1 groups. Results: A total of 366 ACS patients were included in this study. The mean age of the patients was (65.9±10.3) years. There were 59 MACEs and 10 all-cause deaths during the mean of (22.3±4.4) months follow-up. After adjusting for age, systolic blood pressure, history of diabetes and Gensini score, the incidence of MACEs was 2.45 times higher in the high HbA1c/ApoA-1 group than in the low HbA1c/ApoA-1 group (95%CI 1.16-5.18, P=0.019). There was no significant difference in all-cause mortality between the high and low HbA1c/ApoA-1 groups (P=1.000). Kaplan-Meier survival analysis showed that patients in the high HbA1c/ApoA-1 group had the highest risk of MACEs, while patients in the low HbA1c/ApoA-1 group had the lowest risk of MACEs (P<0.01). Spearman rank correlation analysis showed that HbA1/ApoA-1 ratio was positively correlated with Gensini score in ACS patients (r=0.274, P<0.01). Conclusion: High HbA1c/ApoA-1 ratio was an independent risk factor for MACEs in ACS patients. Patients with high HbA1c/ApoA-1 ratio had more severe coronary artery disease lesions. HbA1c/ApoA-1 ratio may be used as a potential risk stratification biomarker for ACS patients, it might be useful for the early identification of high-risk population and for predicting the incidence of MACEs among ACS patients.

Objective: To investigate the association between trimethylamine-N-oxide (TMAO) and the degree of coronary atherosclerosis in coronary heart diseases (CHD) patients with type 2 diabetes mellitus. Methods: Consecutive patients, who underwent coronary angiography due to suspected CHD in Beijing Hospital from November 2016 to January 2018, were screened in this cross-sectional study. According to blood glucose level, previous medical history and coronary angiography results, they were divided into CHD without type2 diabetes mellitus(CHD-nDM) group and CHD with type2 diabetes mellitus(CHD-DM) group. Plasma TMAO levels in each group were measured by LC-MS/MS. Spearman correlation analysis was used to evaluate the correlation between TMAO and the number of diseased vessels and Gensini scores. Multivariate logistic regression was used to analyze the correlation between TMAO and high Gensini scores. Results: A total of 590 patients were enrolled in the study, including 238 patients in CHD-DM group and 352 patients in CHD-nDM group. Patients were older, body mass index, blood pressure level, prevalence of history of hypertension and statins use were higher in CHD-DM group than in CHD-nDM group (all P<0.05). The proportion of patients with multivessel disease (2 or more vessels) was also higher in CHD-DM group than in CHD-nDM group (P<0.001). Gensini score was higher in CHD-DM group than in CHD-nDM group (P<0.05). Fasting blood glucose, glycosylated hemoglobin and urea were significantly higher, while low-density lipoprotein cholesterol and hemoglobin were significantly lower in CHD-DM group than in CHD-nDM group (all P<0.05). The levels of TMAO was significantly higher in CHD-DM group than in CHD-nDM group (P<0.001). Spearman correlation analysis showed that TMAO was positively correlated with the number of diseased vessels, Gensini score, age and blood glucose level (r=0.178, 0.189, 0.260, 0.111, respectively, all P<0.01). Multivariate logistic regression analysis showed that, TMAO level was still positively correlated with high Gensini score in CHD-DM group (OR=2.25, 95%CI 1.16-4.38, P=0.017), but not in CHD-nDM group (OR=1.29, 95%CI 0.72-2.31, P=0.386) after adjusting for age, sex, body mass index, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total cholesterol, triglyceride, history of hypertension, hyperlipidemia, smoking and statin use. Conclusions: In CHD patients with tupe 2 diabetes mellitus, the plasma TMAO level is significantly increased and is independent and positively correlated with the degree of coronary artery disease.

Objective To compare the impacts of different nostril on nasotracheal intubation with video laryngoscopy.Methods Totally 120 ASA grade I maxillofacial surgery patients were equally randomized into two groups:group A(left nostril)and group B(right nostril).After rapid induction of anesthesia,the nasal intubation was completed by Tosight video laryngoscope,and the success rate of the first attempt of the tube passing through the nasal cavity was recorded and compared between these two groups.In addition,time of tube through nasal cavity,time of glottis exposure,total intubation time,intubation success rate,and nasal bleeding were recorded.Results The success rate of the first attempt of tube passing through the nasal cavity was not significantly different between groups A and B(84.7% . 81.7%;=0.202,=0.653).The time of tube passing through nasal cavity [(7.3±4.6)s .(7.5±4.1)s;=-0.223,=0.824] and the time of glottic exposure [(6.6±1.4)s .(6.7±1.4)s;=-0.348,=0.728] had no significant differences between two groups.The success rates of first intubation attempt were 100% in both groups.The total intubation time was(35.1±9.2)s in group A and(34.0±7.8)s in group B(=0.663,=0.509).Intubation-related epistaxis was found in 16 cases(27.1%)in group A and in 17 cases(28.3%)in group B( =0.022,=0.882).Conclusion Different nasal approaches have no effect on nasal intubation.

Objective To explore the detection trend of vaginal intraepithelial neoplasia(VaIN)of lower genital tract from 2013 to 2015. Methods A retrospective analysis was undertaken of colposcopy-directed biopsy of cervical, vaginal and vulvar intraepithelial neoplasia lesions include cervical intraepithelial neoplasia (CIN), VaIN and vulvar intraepithelial neoplasia (VIN) in Obstetrics and Gynecology Hospital of Fudan University from January 2013 to December 2015. Results (1) Overall data of CIN, VaIN and VIN:a total of 16732 cases were diagnosed of lower genital intraepithelial neoplasia in 3 years, accounting for 23.20% (16732/72128) of total colposcopy-directed biopsy cases. Among them, CIN, VaIN and VIN accounted for 19.48%(14053/72128), 2.67%(1923/72128), 1.05%(756/72128) of total colposcopy-directed biopsy cases of the lower genital tract, 83.99%(14053/16732), 11.49%(1923/16732), 4.52%(756/16732) of total lower genital intraepithelial neoplasia, respectively. (2) Annual data of CIN, VaIN and VIN from 2013 to 2015. The annual proportion of CIN in all intraepithelial neoplasia of lower gential tract was basically stable, consisting of 86.02%(3955/4598),83.25%(4795/5760) and 83.20%(5303/6374), respectively. The annual proportion of VaIN was gradually increasing, consisting of 8.09% (372/4598), 12.45%(717/5760) and 13.08%(834/6374), respectively. The annual proportion of VIN was gradually decreasing, consisting of 5.89% (271/4598), 4.31% (248/5760) and 3.72% (237/6374), respectively. Conclusion The increasing detection of VaIN from 2013 to 2015 might correlate with the increasing attention to inspection of the entire vaginal wall.

OBJECTIVETo evaluate the clinical value of magnetic resonance (MR) diffusion-weighted imaging (DWI) for diagnosing radiation-induced liver injury (RILI) and detecting changes in hepatic pathology at different post-irradiation times.

METHODSMale New Zealand white rabbits received no irradiation (C0, control group; n = 10) or irradiation of 50 Gy/10F once every other day by virtual three dimensional conformal radiotherapy (3D-CRT) for one day (C1; n = 10), three days (C2; n = 10), two weeks (C3; n = 10), one month (C4; n = 10) or two months (C5; n = 10). One member of all groups were sacrificed for DWI examination and pathologic study on post-irradiation day 1, day 3, week 2, month 1 and month 2. The apparent diffusion coefficient (ADC) values were measured using a range of b values (50, 300, 600, 800 and 1000 s/mm2).

RESULTSHematoxylin-eosin (H-E) staining showed that livers of rabbits in the C3, C4 and C5 groups had the characteristic features of veno-occlusive disease. DWI examination showed that the irradiated livers of rabbits in C2, C3, C4 and C5 groups had significantly lower ADC values than the livers of the non-irradiated rabbits at b values of 300, 600, 800 and 1000 s/mm2 (P less than 0.05). When the b value was 600 s/mm2, the best negative correlation between ADC values and pathological stage was seen for the irradiated livers (Spearman's rank, r = -0.459, P less than 0.01). The threshold ADC value to distinguish the normal group (C0) from an irradiated group (more than or equal toC1) was 1.955 * 10-3 mm2/s at 600 s/mm2 b value. When the b value was 1000 s/mm2, the threshold ADC value to predict an irradiated group with normal H-E staining (C1) from an irradiated group with abnormal H-E staining (more than or equal toC2) was 1.5250 * 10-3 mm2/s; the ADC threshold value was 1.5150 * 10-3 mm2/s to predict groups C0-2 and groups C3-5.

CONCLUSIONDWI has high sensitivity for detecting RILI at three days after irradiation with proper b values. Use of the ADC value is feasible for estimating the evolutionary process of pathological features of RILI damage. DWI may represent an important clinical tool for detection of early pathological changes in RILI.

OBJECTIVETo compare the clinical effectiveness of fiberoptic bronchoscope (FOB)-guided intubation through the Cookgas intubating laryngeal airway(CILA)and the Fastrach intubating laryngeal mask airway (FT-LMA) in the management of anticipated difficult airways.

METHODSSixty patients with all three difficult intubation criterion (thyromental distance<60 mm, interincisor distance<35 mm, and Mallampati class 3 or 4) undergoing elective plastic surgery under general anesthesia were randomly allocated into CILA group (n=30) and FT-LMA group (n=30). After anesthesia being induced and CILA or FT-LMA being inserted, the patients were treated with FOB-guided intubation through CILA or FT-LMA. The success of the intubating laryngeal airway(ILA)insertion and FOB-guided intubation, the number of attempts, and the duration of the successful attempt were recorded.

RESULTSThe ILA was inserted successfully in 30 patients from CILA group and 27 patients from FT-LMA group. Three failed cases in FT-LMA group were inserted successfully with CILA. In CILA group, the first FOB-guided intubation attempt succeeded in 26 patients, and 4 cases were intubated at the second attempt. In 27 patients of FT-LMA group, 20 cases were intubated successfully at the first attempt, 4 cases at the second attempt, and 3 cases failed; of these three failed patients, two patients were intubated smoothly with FOB through CILA at the first attempt, one was intubated by FOB via CILA at the second attempt. The duration of FT-LMA insertion [(35.3±12.8)s] was significantly longer when compared with CILA [(23.9±17.5)s] (P<0.05). However, the duration of FOB-guided intubation through CILA and FT-LMA [(48.6±13.5)s vs.(53.2±14.2)s] and the time of ILA removal [(40.4±10.2)s vs. (38.5±11.3)s] were not significantly different between these two groups (P>0.05). The adverse events during and after intubtion were not significantly different between these two groups.

CONCLUSIONSFOB-guided intubation through CILA and FT-LMA is safe and feasible for the management of anticipated difficult airways. However, in patients with severe scar contracture of face and neck and those with huge expander in neck, the CILA insertion and FOB-guided intubation via CILA is superior to FT-LMA.

OBJECTIVETo compare the clinical effectiveness of blind intubation through the Cookgas intubating laryngeal airway(CILA) or Fastrach intubating laryngeal mask airway(FT-LMA) for anticipated difficult tracheal intubation.

METHODSEighty-six patients with anticipated difficult tracheal intubation who were undergoing elective plastic surgery under general anesthesia were randomly allocated into CILA group(n=43) and FT-LMA group(n=43) . After general anesthesia being induced and CILA or FT-LMA being inserted, the patients were treated with blind intubation through CILA or FT-LMA. In each case, the number and the time of intubating laryngeal airway(ILA) insertion and blind intubation attempts and ILA removal were recorded. The view of glottis under fiberoptic bronchoscope(FOB) via CILA or FT-LMA was recorded. In addition, noninvasive blood pressure and heart rate were recorded before and after intravenous anesthetic induction, at ILA insertion, at intubation, at ILA removal and every minute thereafter for 5 minutes.

RESULTSCILA or FT-LMA was inserted successfully in all 86 patients. The rate of the first successful insertion was not significantly different between two groups(P>0.05) . In CILA group, the first intubation attempt succeeded in 35 patients;5 and 2 cases were intubated blindly at the second and the third attempt, one patient failed who was intubated successfully by FOB via CILA. In FT-LMA group, 32 patients were intubated successfully at the first attempt, 4 at the second attempt, 3 at the third attempt, and 4 cases failed, three of them were intubated smoothly with FOB through FT-LMA, one failed patient was intubated by FOB. The time of FT-LMA insertion(34.2∓13.9) s was significantly longer when compared with CILA(22.4∓18.9) s (P<0.05) . However, the time of blind intubation through CILA and FT-LMA [(46.0∓26.7) s vs.(51.8∓41.1) s]and the time of ILA removal[(39.3∓11.9) s vs.(35.3∓10.4) s] were not significantly different between groups(P>0.05) . Hemodynamic changes during blind intubation in the two groups showed no significant differences(P>0.05) .

CONCLUSIONSBlind intubation via CILA or FT-LMA is safe and effective for anticipated difficult tracheal intubation. Nevertheless, CILA is easier to be inserted, with relatively higher success rate of blind intubation.

OBJECTIVETo evaluate the feasibility of the Shikani Optical Stylet (SOS)-guided intubation through a new Intubating Laryngeal Airway (ILA) in anticipated difficult airways caused by scar contracture of the face and neck.

METHODSThirty-three adult patients with anticipated difficult airways undergoing selective faciocervical scar plastic surgery under general anesthesia were enrolled in this study. After anesthesia induction, a size 2.5, 3.5 or 4.5 ILA was inserted. Following good lung ventilation being verified, the SOS preloaded with an endotracheal tube was inserted via the ILA. Once the clear vocal cords came into view under the SOS, the endotracheal tube was advanced through glottis into the trachea.

RESULTSThe ILA provided an effective airway in all patients. Intubation was successful at the first attempt on 22/33(66.7%) occasions and at the second attempt on 6/33 (18.2%). Intubation failed in 5 (15.1%) patients who suffered from severe limitation of head extension due to scar contracture of the neck. These patients' tracheas were finally intubated using a fibreoptic bronchoscope via the ILA.

CONCLUSIONSThe SOS-guided intubating method via the ILA is a feasible technique in patients with scar contracture of the face and neck. However, in patients with severe limitation of head extension, the use of SOS cannot be recommended. The SOS can be used as an alternative apparatus when the fibreoptic bronchoscope is not available.

OBJECTIVETo observe the effectiveness of conscious sedation with midazolam, propofol and sufentanil for patients in plastic surgery.

METHODS81 patients, scheduled for plastic surgery, were randomly selected to receive conscious sedation with midazolam 0.05 mg x kg(-1) and sufentanil 0.1 microg x kg(-1) intravenously, following by a continuous infusion of midazolam-propofol-sufentanil combination (midazolam 5 mg + propofol 200 mg + sufentanil 10 microg, a total of 23 ml). The initial infusion rate was 0.2 ml x kg(-1) x h(-1), and was adjusted (in 20% of initial infusion rate increment) to maintain OAA/S score as 11 during the operation. The patients' vital signs, discomfort and level of sedation were evaluated at 5 to 10 min intervals until the end of the surgery. The complications (i. e. anoxemia, apnea, restlessness, nausea and vomiting), anesthesia duration and drug consumption were recorded. The drug infusion was discontinued at 5 - 10 min before the end of the surgical procedure. On the first postoperative day, patients were asked to rate their satisfaction with the anesthetic management and whether they would choose to receive the same anesthetic technique if necessary in the future.

RESULTSThe OAA/S score decreased from 20.0 +/- 0 to 11.9 +/- 2.6 after midazolam and sufentanil IV (P < 0.05), and was maintained as 10.5-11.1 during the procedure. At the end of the procedure, the OAA/S score returned to 16.0 +/- 2.2, which was also lower significantly compared with baseline value (P < 0.05). The induction of sedation produced a significant decrease in SBP and DBP (P < 0.05) and no significant changes in heart rate (P > 0.05). At the end of the procedure, SBP, DBP and HR returned to the baseline value. The anoxemia happened in 11 cases, apnea in 5 cases and restlessness in 2. No nausea and vomiting occurred. The anesthesia duration and consumption of midazolam, propofol and sufentanil were (101.1 +/- 42.5) min, (8.4 +/- 3.7) mg, (189.1 +/- 88.7) mg and (18.2 +/- 5.6) microg respectively. In an interview on the first postoperative day, 96% (78/ 81) of the patients were satisfied with their anesthesia and were willing to receive the same anesthetic technique if necessary in the future.

CONCLUSIONConscious sedation with midazolam, propofol and sufentanil is an effective anesthetic technique for patients in plastic surgery.
