Objective To investigate the indications,approaches,and essentials of cranio-orbital surgeries for orbital apextumors.Methods The clinical data of 48 patients with orbital apextumors treated by refined transcranial orbitotomy through superolateral approach were analyzed retrospectively,34 tumors were excised with orbitoptenonal approach,while 14 tumors were excised with orbltotrontal approach,orbitozygomatic approach,or zygomatic-ptefional approach.Results Of the 48 orbital apextumors,33 cases were totally resected,7 cases were subtotally resected,and 6 cases were partly resected.The other 2 cases were taken biopsies.The optic functions improved or retained in 40 cases,7 cases suffered from eye-moving disfunction or visual-acuity declines,and 1 case suffered from hemiparalysis.Conclusions Tumors in the posterior and apex part of the orbit,or tumors extended from the orbit to the cranial,can be well treated through transcranial approach.Appropriate methods may help to bring maximum convenience to exposure and excision of the lesion,and to conserve the functions.Unnecessary injuries could be avoided as well.

Objective To investigate the efficacy and safety of atorvastatin combined with clopidogrel in the treatment of elderly patients with angina pectoris.Methods 90 elderly patients with angina pectoris were randomly divided into the observation group and control group,45 cases in each group.All patients were given conventional treatment and atorvastatin,the observation group was given clopidogrel based on this.The TC,TG,HDL-C,LDL-C,angina attack frequency,duration and adverse reactions,adverse cardiac events of two groups before and after treatment were compared,and the clinical effect was evaluated.Results The total effective rate of the observation group was 9 3.3 ％ (42/45),whichwassignificantlyhigherthan75.6％ (34/45) inthecontrolgroup (x2 =5.67,P ＜ 0.05).After treatment,the TC,TG,HDL-C,LDL-C of two groups were significantly improved than before treatment (t =5.34,4.78,4.56,4.92,4.31,3.92,4.11,4.62,all P ＜ 0.05),the improvement in the observation group was significantly better than that in the control group (t =4.20,4.08,3.98,4.03,all P ＜ 0.05).After treatment,the angina attack frequency and duration of two groups were significantly decreased compared with before treatment (t =6.22,5.78,4.12,4.02,all P ＜ 0.05),and the observation group decreased significantly than the control group(t =4.23,3.99,all P ＜ 0.05).3 cases of adverse reactions and 1 case of adverse cardiac events occurred in observation group,2 cases of adverse reaction and 3 cases of adverse cardiac events occurred in control group.Conclusion Atorvastatin combined with clopidogrel in the treatment of elderly patients with angina pectoris can regulate blood lipid and improve the symptoms of angina pectoris.

Objective To observe the parameters of echocardiography in persistent pulmonary hypertension of the newborn(PPHN),and to discuss the influence of persistent pulmonary hypertension on cardiac geometry and left ventricul ar function.Methods 25 cases with PPHN were selected,including 11 mild,9 moderate,and 5 severe cases.Another 23 cases of neonatal jaundice were selected as control group.The left atrium diameter(LAD),left ventricular end diastolic diameter (LVDd),right ventricular end diastolic diameter (RVDd),right atrium diameter (RAD),left ventricular posterior wall thickness (LVPW),interventricular septum thickness (IVS) were measured by echocardiography.The results of echocardiography were analyzed.Results Compared with the control group,the RVDd and RAD of PPHN group were significantly increased,RVDd and RAD dilated with the increasing of pulmonary artery systolic pressure in PPHN group (t =2.53,7.09,2.14,4.77,2.88,2.04,4.59,7.12,2.34,5.12,3.07,all P ＜0.05) ;LVDd decreased in severe group (14.80 ±2.16) mm compared with that in the control group (15.26 ±1.83) mm,mild (16.55 ± 1.50) mm and moderate group (15.67 ± 1.87) mm(t =3.76,4.80,3.74,all P ＜ 0.05).Conclusion Echocardiography is one of the most important method to diagnose PPHN,and can be observed in newborns with non-invasive cardiac changes directly.lt has important value in judgement of severity degree,and provide a reliable basis for clinical diagnosis and treatment.

Objective To evaluate the prognosis and safety of long-term oral Branched-Chain Amino Acids (BCAAs) for patients with cirrhosis.Methods Randomized controlled trials (RCTs) were identified from CBM (between January 1978 and September 2013),CNKI (between January 1979 and September 2013),PubMed (between January 1970 and September 2013),EMBASE (between January 1970 and September 2013),and Cochrane Library (issue 4,2013).Publications of the RCTs on the treatment of cirrhosis with oral BCAAS were included and analyzed according to the criteria of Cocbrane handbook.Results Six RCTs involving 1 047 patients were included.The results showed that oral BCAAs improved the event-free survival when compared with the control group [RR =1.13,95％ CI =(1.05,1.23),P =0.001].BCAAs supplements had no effect on mortality or had no definite effect on the deteriorative rate of minimal hepatic encephalopathy (MHE) or quality of life (QOL).As reported in some trials,the main side effects of BCAAs were gastrointestinal symptoms.Conclusions Long-term oral BCAAs may improve event-free survival in cirrhotic patients.However,no definite conclusion can be made without evidences from larger,randomized,double-blind,placebo-controlled,and multicenter trials.

Objective To investigate the association between diet during pregnancy and hypertensive dis-order complicating pregnancy ( HDCP ) , so as to provide a theoretical basis guiding appropriate diet during pregnancy.Methods Using 1∶2 matched case-control study method, we selected pregnant women delivered in Anhui Women and Child Health Care Hospital from January to December 2014, and interviewed them with food frequency questionnaire.The relationship between intake frequency of various food and HDCP was analyzed. Results A total of 543 women were included in this study, including 181 cases and 362 controls.Mann-Whit-ney U test results showed that the frequencies of meat and fish, eggs, beans, nuts, milk, and pickled food con-sumption were significantly different between the cases and the controls (all P<0.05);while the differences in cereals, vegetables, and fruits consumption frequency between cases and controls were not statistically signifi-cant (all P>0.05).Multivariate Logistic regression analysis showed that higher intake frequencies of beans (OR=0.746, 95%CI:0.645-0.862), eggs (OR=0.789, 95%CI:0.693-0.898), and milk (OR=0.822, 95% CI:0.725-0.931) were associated with lower risk of HDCP; in contrast, higher intake fre-quency of pickled food was associated with higher risk of HDCP (OR=1.190, 95% CI:1.054-1.344). Conclusions Beans, eggs, and milk may be protective factors for HDCP, while pickled food may be risk fac-tor of HDCP.Diet during pregnancy should be appropriate and following scientific guidelines.
