Objective To evaluate the influence of gestational diabetes mellitus (GDM) on maternal and perinatal outcomes in twin pregnancies. Methods We retrospectively analyzed the clinical features of both twin and singleton pregnancies, which delivered in Guangzhou Women and Children's Medical Center between January 1, 2012 and December 31, 2013. The twin pregnancies were divided into two groups:those with (GDM-T, n=51) and without GDM (non-GDM-T, n=130), which were matched by maternal age and delivery time (within one month) in a ratio of 1∶2 among singleton pregnancies with (GDM-S, n=102) and without GDM (non-GDM-S, n=102), respectively. The differences of adverse maternal and perinatal outcomes among these four groups were examined. The overall assessment of pregnancy outcomes was completed using Delphi method. Statistical analysis was performed with one-way analysis of variance, t test, Kruskal-Wallis test, rank test, Chi-square test or Fisher's exact test. Results (1) When compared to GDM-S and non-GDM-S group respectively, less women conceived with the help of assisted reproductive technology, higher proportion of women underwent and gestational age at delivery tend to be earlier in GDM-T and non-GDM-T group (all P<0.01). In oral glucose tolerance test,the fasting blood glucose level of GDM-T group was higher than the other three groups (F=21.716, P<0.01), the glucose levels at 1 and 2 h were higher than non-GDM-T and non-GDM-s respectively (both P<0.01), but no significant difference was found when compared with GDM-S group (P>0.01). Similarly, no significant difference was found in prenatal glycosylated hemoglobin value between GDM-T and GDM-S group (P>0.01). (2) There was no significant difference in the incidences of hypertensive disorders of pregnancy, anemia, premature rupture of membranes, oligohydramnios, placental abruption, postpartum hemorrhage, asphyxia neonatorum, small for gestational age, hypoglycemia of newborn, hyperbilirubinemia of newborn and perinatal death between GDM-T group and the other three groups(all P>0.01). Higher incidences of hypertensive disorders of pregnancy and postpartum hemorrhage were shown in the GDM-T group than in the GDM-S and non-GDM-S groups, respectively (both P<0.01). The incidences of preterm birth in GDM-T and non-GDM-T group were both higher than that in GDM-S and non-GDM-S, respectively [54.9%(66/102), 53.8%(140/260), 5.0%(10/102) and 3.0%(6/102), all P<0.01], while no significant difference was found between GDM-T and non-GDM-T group (P>0.01). (3) The overall assessment of pregnancy outcomes did not show any difference between GDM-T group and the other three groups (χ2=6.707, P>0.01). However, the score for fetal outcomes in the GDM-T group was higher than in the GDM-S and non-GDM-S group, but lower than in non-GDM-T group [M(Q)=1.0(2.3), 0.0(3.0), 0.0(0.0), 1.0(2.8) score, χ2=122.818, P<0.01]. Conclusions GDM does not increase the risk of adverse pregnant outcomes in twin pregnancies.

Objective To provide the evidences for the management strategies of ventilator-associated pneumonia (VAP) in neonates,we systematically reviewed all related studies and analyzed the high-risk primary disease and medical factors of VAP in neonates.Methods We retrieved all related studies in CNKI,Wanfang,VIP,CBM,Pubmed and Embase and evaluated their quality by Newcastle-Ottawa Scale and analyzed all data by qualitative and Meta-analysis.Results There were 12 case-control studies with higher methodological quality and involving 1 994 neonates and with 708 VAP patients.Six studies involving 872 neonates were included,the odds ratio of respiratory distress syndrome(OR=2.81) and malnutrition(OR=5.18) had significant differences between VAP and non-VAP group.Seven studies involving 1 110 neonates were included and the odds ratio of patients with corticosteroids (OR=3.12),central inhibitors (OR=2.31),antacids (OR=4.35) and Gamma globulin with large doses (OR=2.35) had significant differences between VAP group and non VAP.Four studies involving 554 neonates were included and the odds ratio of patients with closed chest drainage (OR=1.81)and umbilical vein catheterization (OR=9.19) had significant differences between VAP group and non VAP.Six studies involving 1 139 neonates were included and the odds ratio of patients with parenteral nutrition (OR=1.82)and blood transfusions (OR=2.49) had significant differences between VAP group and non VAP.Conclusions Our study confirms that the respiratory distress syndrome and malnutrition corticosteroids,central inhibitors,antacids,Gamma globulin with large doses,closed chest drainage,umbilical vein catheterization,parenteral nutrition and blood transfusions are important risk and early-warning factors.

Background Normal adult optic disc rim width follows inferior ≥ superior ≥ nasal ≥ temporal (ISNT) rule.Analysis of the optic disc structural parameters with Heidelberg retina tomograph (HRT) can understand whether ISNT principle is suitable to other optic disc structure parameters.Objective This study was to investigate the characteristics of optic nerve head structure parameters in normal Chinese adults.Methods The parents of twins who participated Guangzhou Twin Eye Study were enrolled in Zhongshan Ophthalmic Center from 2006 June to 2011 August.All subjects received the routine eye examinations,including visual acuity,slit lamp microscope,direct ophthalmoscope examination,auto-refraction examination and HRT Ⅲ examination.All data from the right eyes were collected and analyzed.HRT values from different quadrants of optical nerve head were compared with one-way analysis of variance,and the multiple comparison between quadrants was carried out by Bonferroni test.The differences of optical nerve head parameters in different gender were analyzed using independent sample t test and Bland-Altman test.Results In this study,1672 eyes of 1672 subjects were included,with the 759 male and 913 female persons and average age of (41.8±5.3)years.No significant differences were seen in the disc area (DA)between the superior and inferior,as well as the nasal and temporal quadrants among the subjects (P＞0.05).In addition,there were not significantly different in the rim area (RA) between the superior and nasal disc as well as the rim volume (RV) among the inferior,superior and nasal disc (P＞O.05).However,significant differences were found in the cup area (CA),cup/disk area ratio (C/DAR),cup volume (CV),mean cupdepth (MCD),maximum cup depth (MxCD),height variation contour (HVC),cup shape measure (CSM),mean retinal nerve fiber layer thickness (mRNFLT) and retinal nerve fiber layer cross section area (RNFLcsa) among the different quadrants (P＜0.001).The local differences from only DA and RA complied with an ordination of the ISNT rule.The values of DA,CA,C/DAR,CV,MCD,MxCD from male individuals were higher,but those of the RV,HVC,mRNFLT RNFLcsa were lower in comparison with female individuals.Nevertheless,all the differences were ＜ 0.1 with a maximal mean difference in DA and CA (both 0.07 mm2).Conclusions The optical nerve head configurations measured by HRT have different distributing characteristics in four quadrants in normal adults.Most parameters show the higher values in the inferior and superior than those in nasal and temporal of disc,but DA and RA meet ISNT rule.The differences of most parameters between male and female subjects can be ignored.

Background Heidelberg Retinal Tomograph (HRT) has been widely used in clinical diagnosis of glaucomatous optic neuropathy,importantly,the measurement results of HRT may be affected by myopia.Therefore,studying the effect of different refractive status and axial length on structural parameters of the optic disc is important.Objective This study was to evaluate the influence of refractive error and axial length to optic nerve head parameter measured by HRT.Methods The parents who participate in Guangzhou Twin Study were enrolled in this investigation from July 2006 to August 2011.The regular eye examinations,including visual acuity,slit lamp,fundus,auto-refraction,HRT-Ⅲ and intraocular lens (IOL) Master,were performed on all the subjects.Thc data from right eyes of subjects were collected and analyzed.The linear correlation analysis and multiple linear regression analysis were applied to analyze the correlation between HRT optic papilla configuration parameter and equivalent sphere and ocular axis length.Results A pilot prospective series cases observational study was designed.1748subjects were enrolled in this study.The disc area (DA) (P=0.021),rim area (RA) (P＜0.001),rim volume (RV) (P＜0.001),mean retinal nerve fiber layer thickness (mRNFLt) (P＜0.001) and retinal nerve fiber layer cross section area (RNFLcsa) in the high myopia were greater than those of the emmetropic group,with significant difference between the two groups (P＜0.001).However,the cup area (CA),cup/disk area ratio (C/DAR) and cup volume (CV) were less in the high myopic group than those of the emmetropic group (P=0.004,P＜0.001 and P＜O.001),respectively.In the mild-moderatc myopic group,the RV,mRNFLt and RNFLcsa were greater than those of the emmetropic group (all of the P value less than 0.001),but the numbers of DA,CA,C/DAR,and CV were less than those of the emmetropic group,the differences were significant and their P valuables were 0.038,＜ 0.001,＜0.001 and 0.001 respectively.The differences of structure parameters between the hyperopia group and the emmetropic group were not statistically significant (P＞0.05).The DA,CA,RA,C/DAR,CV,RV,mean cup depth (MCD),maximum cup depth (MxCD),cup shape measure (CSM),mRNFLt and RNTLcsa were (2.04±0.43) mm2,(0.49±0.34) mm2,(1.55 ± 0.34) mm2,0.23-0.13,(0.11 ± 0.12) mm3,(0.45 ± 0.19) mm3,(0.21 ± 0.09) mm,(0.60±0.21) mm,-0.21 ± 0.07,(0.29 ± 0.07) mm and (1.46 ± 0.36)mm2,respectively,in the 1748 eyes of 1748 subjects.No significant correlation was found between the DA value with SE (r=-0.032,P =0.186).However,weaker positive correlations were seen between the CA,C/DAR,CV,MCD,MxCD with SE (r=0.139,0.163,0.130,0.004,0.054,P＜ 0.05) and negative correlation between RA,RV,mRNFLt and RNFLcsa with SE (r =-0.178,-0.331,0.241,-0.239,P＜0.001).With the increase of the ocular axial length,the DA,RA,RV,mRNFLt and RNFLcsa values were enlarged,and the CV value was smaller.With the increase of CA,the RA,C/DAR,CV,RV,MCD,MxCD,CSM and RNFLcsa values elevated,but mRNFLt value was decreased.Conclusions Refractive error is not associated with DA,but the measuring results are different among various refractive groups.Refractive error,ocular axial length and DA affect the measuring result of HRT.

Objective To summarize the experience in the diagnosis and treatment of mucinous cystic neoplasms (MCN) of the pancreas. Methods The clinical data of 20 cases who were diagnosed as MCN of the pancreas in the affiliated hospital of Qingdao university from January, 2003 to June, 2008 were collected, data including clinical manifestations, pathological features, treatment and survival were analyzed retrospectively. Results The clinical manifestations mainly included abdominal pain or discomfort, nausea, vomiting; 11 patients had abdominal tenderness, 6 patients had palpable abdominal mass. All the patients underwent ultrasound and CT scan examinations, 13 patients were diagnosed as having benign MCN of the pancreas, 4 were serous cystadenoma, 3 were mucinous cystadenocarcinoma. The tumors were located in the body and tail of the pancreas, with a mean diameter of 4 - 14 cm. All the 20 cases received surgical treatment. The procedures mainly included pancreaticoduodenectomy and resection of pancreatic body and tail. Pathological examinations confirmed there were 10 patients with benign MCN of the pancreas, 3 were borderline mucinous cystadenomas and 7 mucinous cystadenocarcinomas. After a mean follow-up of 26 months, patients with benign MCN of the pancreas or borderline mucinous cystadenomas were still alive without recurrence, the three year survival of patients with mucinous cystadenocarcinomas was 50%. Conclusions MCN of the pancreas mainly occurred in female, and there was no specific clinical features, preoperative ultrasound and CT scan examinations could help to diagnose this disease. Surgical resection was the only effective method to cure MCN with good prognosis.
