ObjectiveTo investigate the features of the cortisol ( COR),thyroid hormone and autonomic function of anxiety disorder,and to observe the relationships between clinical subtypes,insomnia,gender factors and the neuroendocrine and autonomic function.Methods60 anxiety disorder patients and 60 healthy controls were randomly selected from a three-grade class A hospital over the same period.Blood at 8:00am to test the plasma COR,T3,T4,TSH level and examined the heart rate variability (HRV) on the same day,the anxiety disorder patients also finish the self-rating anxiety scale (SAS).ResultsThe plasma COR,TSH level and LF/HF index were significantly higher( (531.58 ± 218.59 ) nmol/L,P＜ 0.0l ; (3.50 ± 1.35 ) MIU/L,P＜ 0.05 ;3.87 ± 3.37,P＜0.0l ),while the SDNN,LF,HF index were significantly lower in anxiety disorder than that in the control group (27.34±13.13,P＜0.01;338.72 ±396.34,P＜0.01;135.77 ±149.95,P＜0.01).The plasma COR,TSH level and LF/HF index were significantly higher(P ＜ 0.05,P＜0.01,P＜0.01 ),while the SDNN and HF index were significantly lower in panic disorder than that in the generalized anxiety disorder (P ＜ 0.01 ).The plasma COR,TSH level and LF/HF index were significantly higher,while the SDNN,LF,HF index were significantly lower in panic disorder than that in the control group (P＜0.01 ).The plasma COR was significantly higher,while the SDNN and HF index were significantly lower in generalized anxiety disorder than that of the control group (P＜0.01 ).The plasma COR level and LF/HF index were significantly higher (P＜0.01,P＜0.05),while the SDNN,LF,HF index were significantly lower in anxiety disorder with or without insomnia than that in the control group (P＜ 0.01 ).The plasma TSH level was significantly higher in anxiety disorder with insomnia than that in the control group (P＜ 0.05 ).There were no significant difference of the neuroendocrine and autonomic function between anxiety disorder with or without insomnia (P ＞ 0.05 ).The plasma COR,TSH level were significantly higher,while the SDNN,LF,HF index were significantly lower in the female group than that in the male group (P＜0.01).The total SAS scores were significantly positively correhted with plasma COR levels,and was significantly negatively correlated with SDNN,HF index in the anxiety group.ConclusionThere are neuroendocrine and autonomic nervous system dysfunctions in anxiety disorder,and these dysfunctions are related with clinical subtypes,insomnia,and gender.

OBJECTIVETo explore the relationship between salivary proteome and dental caries and to promote the biomarker studies of dental caries susceptibility by comparing the salivary proteome of caries-active children and caries-free children with electrospray ionization ion-trap tandem mass spectrometry (ESI-MS/MS).

METHODSTen caries-active children and ten caries-free children were sampled. The salivary proteome of the two groups was studied, and the differential protein between the two groups was analyzed by ESI-MS/MS after sodium dodecyl sulfate polyacrylamide gel electrophoresis, filter-aided sample preparation, and liquid chromatography.

RESULTSThe concentration of salivary protein was higher in the caries-active group than in the caries-free group. The polypeptide counts of thecaries-active and caries-free groups were 602 and 481, which belonged to 286 and 227 proteins, respectively. The differential polypeptide count of the two groups was 361, and the differential protein count was 118. The detected proteins included matrix metalloproteinase-9 (MMP9), mucin-7 (MUC7), lactotransferrin (LTF), carbonic anhydrase 6 (CA6), azurocidin (AZU), and cold agglutinin.

CONCLUSIONThe total salivary protein was higher in the caries-active group than in the caries-free group. The preliminary detection of differential proteins (MMP9, MUC7, LTF, CA6, AZU, and cold agglutinin) may lay some foundation for biomarker research of dental caries susceptibility.

Objective To observe the anesthesia and recovery results of sevoflrane and remifentanil combined anesthesia in open or laparoscopic surgeries. Methods 60 cases of ordinary surgeries from the department of gynecology and general surgeries were included in this study with 30 cases in each group. (1)recording total sevoflurane inhalation time, muscular relaxant amount, end tidal sevoflurane concentration;(2)recording BP,HR at 10 min after induction,operation staring and ending,ventilation recovery, opening eye and extubation period;also sevoflurane concentration 5 min after stopping medicine and ventilation recovery;recording time period between surgery ending and autonomous respiration recovery , eye opening and extubation. Results No any adverse events happen in each patient.the sevoflurane inhalation time in open surgery group was (157.20 ± 47.28) min, longer than that of laparoscopic surgeries group (73.50 ± 11.23)min(P<0.05), we had seen no statistical significance in all other index observed (P>0.05). Conclusion Sevoflurane combined remifentanil anesthesia can achieve stable intra-operative maintenance and rapid postoperative recovery quality , we suggest the widespread usage of it in clinic.

Objective To determine the clinical indications and detection efficiency of non-invasive prenatal testing (NIPT) in Jiangsu Province, China. Methods A total of 13 041 pregnant women from nine hospitals in Jiangsu Province who voluntarily accepted NIPT for chromosome 13, 18, 21 and sex chromosome from January 1, 2012 to December 31, 2013 were analyzed retrospectively. All cases were singleton pregnancies and spontaneously conceived. Invasive prenatal diagnosis followed by fetal chromosome karyotype analysis was recommended in high-risk women following NIPT. The clinical indications and positive predictive value of NIPT were conducted. Results NIPT detected 88, 19, 9 and 64 cases at high risk for trisomy 21, trisomy 18, trisomy 13 and X chromosome aneuploidy, and the positive rate was 0.67%, 0.15%, 0.07% and 0.49%, respectively. Among the 74, 13, 8 and 44 high-risk cases who accepted chromosome karyotype analysis, respectively, 67 cases were diagnosed with trisomy 21, 12 cases with trisomy 18, one case with trisomy 13, and 18 cases with numerical X chromosome abnormality. The positive predictive value was 90.5% (67/74), 12/13, 1/8 and 40.9% (18/44), respectively. One pregnant woman who was reported as high-risk trisomy 21 following NIPT, but high-risk trisomy 18 at prior serum screening, was eventually diagnosed with fetal trisomy 18 by chromosome karyotype analysis, whose placenta was a mosaic of trisomy 21 and trisomy 18. High-risk following serum screening was the most common indication for NIPT accounting for 46.4% (6 056/13 041), followed by low-risk but asking for testing (28.9%, 3 773/13 041) and advanced age (20.5%, 2 673/13 041). Conclusions High-risk, low-risk but asking for testing and advanced maternal age are common indications for NIPT in Jiangsu Province. The positive predictive value of NIPT for trisomy 21 or trisomy 18 is relatively high, but is much lower for trisomy 13 or X chromosome aneuploidy.

Objective To summarize the experience of surgical treatment in patients with uremia and severe coronary artery disease, and reduce the perioperative risk thereof. Methods Sixteen chronic renal failure patients who were received haemodialysis and underwent coronary artery bypass grafting (CABG) during the period of February 2009 to December 2016 in Tianjin First Central Hospital were assessed in this retrospective study. Of the 16 patients, 8 patients and 6 patients were treated with off pump and on pump CABG respectively, one patient was treated with CABG and resection of ventricular aneurysm, and one patient was treated with CABG and tricuspid valve replacements. The renal function changes in preoperative and postoperative periods, 2-day and 1-week after surgery were observed. Echocardiography was used to evaluate cardiac function. The improvement of angina was recorded. Results Fourteen patients were successfully withdrawn from ventilator therapy within 24 h after surgery. The tracheal intubation was removed 65-hour after surgery in one patient. One patient died of multiple organ failure on the seventh day after surgery. The average length of ICU staying and in-hospital stay were (125.5 ± 21.6) h and (28.6 ± 7.4) days respectively. The serum creatinine (sCr) and blood urea nitrogen (BUN) were higher in two days after surgery than those before the operation (P < 0.05). Fifteen patients which followed up (the final follow-up date was February 2017) showing cardiac functionⅠ-Ⅱ, ejection fraction (EF)>0.40, and no angina occurred. Conclusion CABG is relatively safe for patients with end-stage renal disease and severe coronary artery disease. CABG can significantly eliminate angina symptoms with satisfactory clinical effect.

The incidence of dextrocardia is lower. The dextrocardia is often associated with congenital anatomical abnormalities. The patient with normal cardiac structure of dextrocardia and severe coronary heart disease that needs coronary artery bypasss is rarer. This article summarizes the perioperative management and surgical experience of dextrocardia with bypass surgery via a clinical case.

Objective To investigate the risk factors of postoperative atrial fibrillation (POAF) in patients with on-pump coronary artery bypass grafting (ONCAB). Methods The clinical data of 200 patients with ONCAB were retrospectively analyzed. The patients were divided into POAF group (n=52) and non POAF group (n=148) according to the occurrence of POAF after operation. The perioperative data including age and gender of all patients were collected and analyzed. The index of opinion of statistical results was classified by two categories Logistic regression analysis, and the related risk factors of POAF were analyzed. The receiver operating characteristic (ROC) curves of the age, red blood cell (RBC), left atrial diameter (LAD) and left ventricular ejection fraction (LVEF) were analyzed in two groups. Results The incidence rate of POAF was 26%, mostly occurred in the postoperative period from 1 d to 3 d. Compared with non POAF group, the age, the proportion of patients with age≥62.5 years or older, the proportion of patients with LAD≥35 mm, left ventricular end-diastolic diameter and perioperative transfusion of RBC were increased in POAF group, and data of mechanical ventilation time, ICU stay time and hospitalization time were prolonged, but the LVEF level decrease ( P<0.05). Among them, the elderly (≥62.5 years), increased LAD (≥35 mm), the higher perioperative transmission amount of RBC were the independent risk factors of POAF after ONCAB, and the higher LVEF was a protective factor for ONCAB. The optimal thresholds for age, RBC, LAD and LVEF were 62.5 years, 1U, 35.5 mm, and 0.34. Conclusion The occurrence of POAF after ONCAB is related with age (≥62.5 years old),LAD≥35 mm and perioperative transfusion of RBC, which can be used as clinically to predict the occurrence of POAF.

Objective To identify the risk factors for acute kidney injury (AKI) in overweight patients who underwent surgery for the treatment of acute type A aortic dissection(TAAD).Methods A retrospective study including 108 consecutive overweight patients(body mass index(BMI) ≥24) between January 2010 and May 2013 in Beijing Anzhen Hospital was performed with Sun's procedure of total aortic arch replacement and frozen elephant trunk implantation.AKI was as defined according to Acute Kidney Injury Network (AKIN) criteria based on serum creatinine(sCr) or urine output.Results The mean age of the patients was(43.69 ± 9.66) years.During the postoperative period seventy-two patients(66.7％) developed AKI.The overall postoperative mortality rate was 7.4％,8.3％ in AKI group and 5.6％ in non-AKI group.There is no statistically significant difference between the two groups(P =0.32).A logistic regression analysis was performed to find out the independent risk factors for AKI:elevated preoperative sCr level and postoperative drainage volume.Renal replacement therapy(RRT) was performed in fifteen patients (13.9 ％).Conclusion A higher incidence of AKI (66.7 ％) in overweight patients following acute TAAD was identified.The logistic regression model found out elevated preoperative sCr level and 72 hour drainage volume as the two independent risk factors for AKI in overweight patients.More attention should be paid to prevent AKI in overweight patients following TAAD.

OBJECTIVE:To systematically review the efficacy and safety of insulin glargine versus insulin detemir in the treat-ment of type 2 diabetes,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed,EM-Base,Cochrane Library,CBM,CJFD,VIP and Wanfang database,randomized controlled trials (RCT) about the clinical efficacy and safety of insulin glargine versus insulin detemir in the treatment of type 2 diabetes were collected. Meta-analysis was performed by using Rev Man 5.2 software after data extraction and quality evaluation by Cochrane 5.1.0. RESULTS:A total of 18 RCTs,in-volving 3 638 patients were included. Results of Meta-analysis showed there was no significant difference in reducing glycosylated hemoglobin[MD=0.08,95%CI (-0.01,0.17),P=0.09];fasting blood glucose level in insulin glargine group was significantly lower thaninsulin detemir,the difference was statistically significant [MD=0.15,95%CI(0.03,0.27),P=0.02]. And there was no significant difference in the incidence of hypoglycemia [OR=0.97,95%CI(0.91,1.03),P=0.25];the degree of body mass gain ininsulin detemir was significantly lower than insulin glargine group [MD=-0.95,95%CI(-1.06,-0.85),P=0.003],but the in-cidence of injection site reactions was significantly higher than insulin glargine group [OR=2.28,95%CI(1.16,4.50),P=0.02],the differences were statistically significant. CONCLUSIONS:The insulin glargine has better efficacy,than insulin detemir with lower incidence of injection site reactions but higher degree of body mass gain than insulin detemir in the treatment of type 2 diabetes.

Objective To summarize the treatment experiences in patients with cardiac surgery-associated acute kidney injury (CSA-AKI). Methods The clinical data of 9 patients with acute renal injury after orthotopic heart transplantation in our hospital from January 2009 to July 2016 were retrospectively analyzed. Three patients were required the high-dose diuretics (furosemide, >80 mg/d) and six patients were received continuous renal replacement therapy (CRRT). The levels of serum creatinine (Cr) and estimated glomerular filtration rate (eGFR) were compared before and after heart transplantation and after the treatment of AKI. The quality of life was observed in patients in perioperative period. Results After the treatment of diuretics or CRRT, patients showed renal function recovery with significant decreased Cr levels and increased eGFR compared with the postoperation. The patients with diuretic therapy revealed a better eGFR recovery than those with CRRT. Conclusion CSA-AKI should be based on the severity of disease, and comprehensive treatment should be taken to reduce renal damage.
