Objective To explore the prognosis of children under different modes of delivery in the oli?gohydramnios patients,in order to reduce unnecessary cesarean section rate. Methods One hundred and forty?eight cases of oligohydramnios from September 2013 to October 2015 in the First Affiliated Hospital of Tsinghua University were reviewed,including 74 cases of vaginal delivery,54 cases of vaginal delivery group,20 cases for fetal heart abnormalities in the induction of labor or labor in the process or abortion failure emergency caesarean birth operation( pilot transfer of emergency cesarean section delivery group);direct line selective cesarean section in 74 cases. The delivery surround unripe ending of three kinds of delivery mode was compared,and gestational weeks,estate, cervical score, maximal amniotic fluid dark area vertical depth ( AFV), amniotic fluid index ( AFI) ,fetal size,water treatment and abortion case of the vaginal delivery and emergency caesarean birth were statistically compared. Results Both fetal heart abnormality and amniotic fluid of third degree incidence of trial production of emergency cesarean section group was 80. 00%( 16/20) ,of vaginal delivery group was respectively 11. 11%( 6/54) ,29. 63 ( 16/54) ,and of selective cesarean section delivery group was 0 and 9. 50%( 7/74) re?spectively,the difference between the 3 groups was statistically significant( P<0. 05) . The gestational age of vagi?nal trial production successfully delivery group and transfer of emergency cesarean section production group was respectively (39. 33+0. 13),(40. 20+0. 2) weeks, the parity was 0 were 45 cases,20 cases respectively,the parity was 1 were 9 cases,0 case respectively;AFV was ( 2. 14+0. 06) cm,( 1. 86+0. 08) cm respectively;the water treatment rates were 66. 67%( 36/74) and 30%( 6/20) respectively;the difference between the two groups was statistically significant(P<0. 05). Induction:in vaginal delivery group,there were 24 cases of spontaneous labor without induction,12 cases treated with misoprostol for cervical mature after vaginal delivery,12 cases of contraction oxytocin induction of labor with vaginal delivery,6 cases of misoprostol for cervical ripening after va?ginal delivery;in emergency cesarean section group,there were 2 cases of natural labor,8 cases of oxytocin,miso?prostol after oxytocin in 10 cases. There was significant difference between the two groups ( P<0. 001 ) . Conclusion Low risk pregnancy, fetal reserve ability of oligohydramnios in vaginal delivery is feasible. Water treatment,gestational age < 40 weeks, the parity more than 1 times,AFV>2 cm,the high rate of abortion sensi?tive pregnant women with high rate of vaginal delivery.

Objective To explore the characteristics of cognitive impairments in euthymic patients with early-on?set or late-onset bipolar I disorder (BD-I). Methods Ninety-four with onset age less than 21 (early onset group), 41 eu?thymic patients with onset age above 35 (late onset group) and 135 normal controls with matched education and age were enrolled. Seven classical neuropsychological tests were used to assess attention, processing speed, working memory and executive functions. Results The early-onset group was significantly worse than its corresponding normal controls in 14 indexes of all tests, including digital symbol, digital span, visual graphic reproduction (c1 and c2), time of TMT-A and TMT-B, verbal fluency, number of sorting, error and preserved error in WCST, as well as total score, completed missions, planning time and executing time in TOH (P<0.05). Moreover the effect size of difference were more than 0.4 in verbal fluency, time of TMT-A and TMT-B, and executing time in TOH. Compared with its matched control group, the late-on?set group was significantly impaired in 9 indexes, including digital span, visual graphic reproduction (c1,c2 and total), time of TMT-A, number of error and preserved error in WCST, as well as total score and completed missions in TOH (P<0.05), merely two indexes of TOH with effect size more than 0.4, while the late-onset group was no significantly impaired in digital symbol, TMT-B and verbal fluency. Conclusions There are significant cognitive impairments in euthymic BD-I patients with no matter early-onset or late-onset. But it seems that the cognitive impairments in early-onset bipo?lar disorder are more extensive and serious.

Objective To evaluate the relationship between the perfusion mode of neovascularization of carotid plaque in CEUS and the ischemic stroke in transient ischemic attack (TIA) patient.Methods A total of 73 TIA patients according to the inclusive criteria were enrolled.All the patients underwent routine carotid ultrasonic examination.And 61 patients with plaque thicker than 2.5 mm in carotid bifurcation underwent CEUS and follow-up for at least 18 months.All the patients were divided into recurrent and non-recurrent groups.Logistic regression analysis were performed to detect the risk factors for incurrence of ischemic stroke or recurrence of TIA in 18 months.Results There were statistical differences between 2 groups in hypertension,diabetes,hyperlipemia,smoking history,family history of stroke,medication compliance,two-dimensional ultrasound and CEUS characteristics (all P＜0.05).Multivariate Logistic regression analysis showed that all the factors correlated with the recurrency,from big to small order were the CEUS characteristics of carotid plaque,hypertension,medication compliance,diabetes,two-dimensional ultrasound characteristics of carotid plaque.Conclusion CEUS could evaluate the perfusion mode of neovascularization in carotid plaques.For TIA patients,CEUS could predict the incurrence of ischemic stroke or recurrence of TIA,which can guide TIA patients targeted prophylaxis of them.

Objective To evaluate the effects of different energy feeding on the nutritional status, clinical course and outcome of children with congenital heart disease(CHD) in PICU.Methods Forty cases of hospitalized CHD children were selected as research objects from July 1,2016 to February 28,2017.They were randomly divided into two groups,one group(high-calorie milk group,n=20) were fed with high-calo-rie milk and the other(common milk group,n=20)were fed with common milk.The nutritional status of the two groups were calculated by physical measurements, laboratory indicators, nutrition risk screening and resting energy expenditure.This research also calculated the liquid and energy per day,compared their actual feeding situation,assessed their nutritional status and cardiac function at discharge,and compared the hospi-tal stay,preoperative and postoperative mechanical ventilation time and postoperative fever time.Results There was no statistical difference in the assessment of malnutrition during the discharge of high-calorie milk group.In common milk group,the proportion of moderate to severe malnutrition of discharge was significantly higher than that of admission(χ2=2.537,P=0.042).The proportion of moderate to severe malnutrition was great higher in common milk group than that in high-calorie milk group,but there was no statistical difference, and neither in nutritional risk screening nor cardiac function between the two groups at discharge.Albumin and transferrin of high-calorie milk group were significantly higher than those of the common milk group(t =2.195,P=0.034;t=2.064,P=0.046).Also the number of appropriate energy supply and feeding cases in the high-calorie group were higher than those in the common milk group(t=2.334,P=0.025;χ2=10.600,P=0.005).Nine cases underwent cardiopulmonary operation in the two groups respectively.There was no statisti-cal difference in the time of ventilatory support between the two groups before and after operation, but the fever time of high-calorie milk group was significantly lower than that of the common milk group(t=2.439, P=0.027).Conclusion The incidence of malnutrition and undernourishment of children with CHD is high, and the incidence of nutrition risk is high,therefore increasing energy supply of children with CHD without in-creasing the heart load could improve their nutrition status and clinical outcome.

Objective To examine the heritability of neurocognitive functions in bipolar I disorder(BD-I)families and BD-associated cognitive endophenotypes. Methods Seventy-nine nuclear families consisting of euthymic BD-I probands and their healthy parents were recruited. Cognitive functions including attention, working memory, processing speed and executive function were evaluated by 7 classic neurocognitive tests, and the heritability of neuroconitive functions in these families was estimated using parent-offspring regression indexes of quantitative traits.Furthermore,the heritable cognitions were compared between 79 BD probands and 140 normal controls. Results After adjusted by age and education,mistake numbers of Trail Making Test A(TMT-A),total score and completed mission numbers of Tower of Hanoi (TOH) were significantly heritable (P<0.05). The comparison of these heritable cognitions between patients and normal controls showed that TOH total score and TOH completed mission numbers were significantly impaired in the patient group (P<0.05). Conclusion Processing speed and executive function are probably heritable in BD nuclear families. Executive function impairments may be disease-related which could be candidate endophenotypes for bipolar disorder.

Objective To investigate the development and application of blood purification in PICU. Methods The demographic data,diagnosis,length of stay,prognosis,patterns and frequency of blood purifi-cation and complications of PICU patients treated with blood purification in our hospital from 2010 to 2017 were retrospectively analyzed. Results The patients with blood purification accounted for 3. 1％ of hospital-ized children in the same period. From 2010 to 2017,the patients and times with blood purification increased by 370. 6％ and 398. 3％ respectively. The times of continuous veno-venous hemodiafiltration(CVVHDF), plasma exchange and hemoperfusion increased by 135. 2％,6300％ and 1600％ respectively. The frequency of CVVHDF,plasma exchange and hemoperfusion accounted for 42. 8％(492/1151),33. 5％(386/1151), and 23. 7％ (273/1151) respectively. Drug and toxic poision accounted for the highest proportion of 28. 6％(81/284),neurological diseases accounted for 20. 8％(59/284),sepsis with multiple organ dysfunction syn-drome accounted for 18. 0％( 51/284 ) , digestive system diseases, autoimmune diseases, renal diseases and metabolic diseases accounted for 14. 4％( 41/284 ) ,4. 9％( 14/284 ) ,4. 9％ ( 14/284 ) and 4. 2％( 12/284 ) respectively. The cure rate was 63. 8％. Complication included thrombus. Conclusion Blood purification has become the preferred modality for the management of critically ill children. Pediatric blood purification tech-niques have developed rapidly in our PICU and domestic pediatric. Further specification is required,so that it may represent the adequate choice for critical ill children.

OBJECTIVETo assess the association of neural development-related genes LIS1and TSNAX with bipolar disorder in a Chinese Han population.

METHODSThree hundred and eight five patients (including 188 males and 197 females) from Guangzhou Brain Hospital with bipolar disorder meeting the Diagnostic and Statistic Manual of Bipolar Disorder (BDI) (Fourth Edition) criteria and 475 healthy controls from the local community were recruited. Ten single nucleotide polymorphisms (SNPs) of the LIS1 and TSNAX genes were genotyped by GoldenGate genotyping assay on an Illumina Beadstation 500 machine. Association analyses of SNPs and haplotypes were performed with Plink 1.07 software.

RESULTSAnalysis of the total sample has failed to find any association of SNP or haplotype of the two genes with BDI (P> 0.05). When patients were divided into subgroups with or without psychotic symptom, no significant association of the two genes was found with psychotic BDI or non-psychotic BDI (P> 0.05). No significant association was found between any SNP and haplotype of two genes and female BDI or male BDI, nor were significant association found between age of onset and LIS1 and TSNAX gene polymorphisms.

CONCLUSIONOur results indicated that LIS1 and TSNAX genes are not associated with susceptibility to bipolar I disorder in Chinese Han population.

Objective:To explore the clinical significance of thrombelastography (TEG) and conventional coagulation tests (CCTs) in the diagnosis of trauma-induced coagulopathy(TIC) and the risk factors for TIC.Methods:Traumatic patients hospitalized in PICU at Shengjing Hospital of China Medical University from December 1, 2017 to January 31, 2019 were divided into three groups according to injury severity score(ISS): non-severe group(≤16 points), severe group (17-25 points) and extremely severe group(>25 points). All patients received 2.5 mL of venous blood at admission/after 6 h, 12 h, 24 h, and 48 h injury to detect TEG and CCTs.The prevalence, time of onset, recovery time of coagulation function and risk factors for TIC were summarized.Results:A total of 64 cases were collected, including 18 non-critical cases, 28 critical cases and 18 extremely critical cases.TEG and CCTs were used to diagnose TIC in nine cases(14.1%)and four cases(6.3%), respectively.TIC could be diagnosed by TEG at 6 hours after trauma, and 12 hours for CCTs.TEG was used to diagnose four cases of hypercoagulability.Univariate analysis showed that female, blood transfusion, transfusion, shock, multiple organ dysfunction syndrome, mechanical ventilation, hypothermia, low age, low glasgow coma scale (GCS) and high ISS were all risk factors for TIC.Logistics regression analysis found that children with high-risk factors such as girl, hypothermia, shock and mechanical ventilation were 4.333, 17.889, 10.208, and 4.479 times more likely to develop TIC than those without high-risk factors.For every 1 score increase in the ISS score, the risk of TIC increased by 1.147.As the age increased by 1 year, GCS increased by 1 point, and the risk of TIC decreased by 0.765 and 0.817, respectively, which were protective factors for TIC.Conclusion:TEG and CCTs are consistent in the diagnosis of TIC, but TEG is more sensitive at an earlier stage and can detect hypercoagulability.Female, shock, hypothermia, low age, high ISS, and low GCS are risk factors for TIC.

Objective:To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China.Methods:A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014.Results:Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade Ⅱ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively.Conclusions:The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.
