Objective To evaluate the significance of standardized ultrasound examination of fetal structures in the ifrst trimester (11-13+6 weeks). Methods The ultrasound data of 29 858 fetuses who underwent the ifrst trimester screening were analyzed retrospectively in Beijing Obstetrics and Gynecology Hospital of Capital Medical University from January 2010 to December 2012 and followed up the cases with structural abnormalities and increased nuchal translucency (NT). Results Among 29 858 fetuses, 328 structural defects were detected in 284 fetuses (0.95%) by ultrasound in the first trimester, including fetal hydrops (124 cases), choroid plexus cysts (36 cases), exencephaly (32 cases), gastroschisis (24 cases), exomphalos (22 cases), cardiac defects (19 cases), megacystis (14 cases), spine abnormalities (10 cases), meningoceles/encephaloceles (9 cases), alobar holoprosencephaly (8 cases), hydrocephaly (7 cases), abnormalities of extremities (7 cases), acrania (6 cases), amniotic band syndrome (4 cases), abdominal cyst (3 cases) and conjoined twins (3 cases). Pregnancy was terminated in all cases (115) with exencephaly, gastroschisis, exomphalos, meningoceles/encephaloceles, alobar holoprosencephaly, hydrocephaly,abnormalities of extremities, acrania, amniotic band syndrome and conjoined twins, and the defects were verified by the gross appearance of fetuses. Two cases of megacystis were turned out to be normal during follow-up while 1 case was proved to be aneuploid and 1 other case progressed to multiple abnormalities during the second trimester. Most choroid plexus cysts, except 1 case of aneuploid, were normal during the second and the third trimester follow-ups by ultrasound. Thirteen cases of fetal hydrops were found to be aneuploids and 4 hydrops cases were proved to be complicated with other structural defects during the second and the third trimester. NT was increased in 422 cases (1.41%), among which 122 cases (28.91%) were complicated with structural defects and/or fetal hydrops. Ninty-nine cases with increased NT underwent chromosomal examination and 38 cases were found to be aneuploides. During the follow-up of 298 cases with increased NT who continued pregnancy, 21 structural abnormalities were found, including cardiac defects (14 cases), neural abnormalities (4 cases) and diaphragmatic hernia (3 cases). Conclusion The standardized fetal ultrasound in the first trimester is a effective tool for the screening of aneupolides and major structural abnormalities.

OBJECTIVETo compare the effects between moxibustion at Guanyuan (CV 4), Shenshu (BL 23), Zusanli (ST 36) and western medication on immune function in children with cerebral palsy.

METHODSA total of 230 children with cerebral palsy were randomly divided into an observation group and a control group, 115 cases in each one. Patients in the observation group were treated with warm moxibustion at Guanyuan (CV 4), Shenshu (BL 23) and Zusanli (ST 36). Patients in the control group were treated with oral administration of pidotimod 10 mL every time. The treatment was given once a day, and 30 days were considered as one session for total 90 days. The changes of T-lymphoctyte subgroups, serum immunoglobulin and development quotient were compared 30 days, 60 days and 90 days into treatment respectively; also the occurrence rate.of disease was observed during 6-month and 12-month follow-up visit.

RESULTSThe T-lymphoctyte subgroups (CD3+, CD4+, CD4+/CD8+), serum immunoglobulin (IgG, IgA) and development quotient were significantly improved 30 days, 60 days and 90 days into treatment (P < 0.01, P < 0.05). Regarding the changes of CD3+, CD4+, CD4+/CD4+, IgG, IgA and development quotient, the control group was superior to the observation group 30 days into treatment (all P < 0.05), and the control group was similar to the observation group 60 days into treatment (all P > 0.05), and the observation group was superior to the control group 90 days into treatment (all P < 0.05). There was no significant difference of CD8+ and IgM before and after treatment in two groups (all P > 0.05). The rate of adverse events was 7.0% (8/115) in the observation group, which was lower than 23.5% (27/115) in the control group (P < 0.01); during 6-month and 12-month follow-up visit, the occurrence rate of disease in the observation group was lower than that in the control group (P < 0.05).

CONCLUSIONMoxibustion at Guanyuan (CV 4), Shenshu (BL 23) and Zusanli (ST 36) can improve immune function of children with cerebral palsy, which is superior to pidotimod.

Objective To analyze psychological changes of patients underwent the hematopoietic stem cell collection and explore the importance of health education in order to support the proceeding of collection smoothly.Methods A total of 50 patients underwent the hematopoietic stem cell collection were divided into two groups:study group(n = 25)and control group(n =25).The control group performed the pure pharmacotherapy while the study group performed health education based on the pharmacotherapy.Results Indicators including the coping style of discomfort symptoms and the knowledge of health education in the study group were better than that in the control group.Conclusions Psychological status of patients plays an important role during collecting proceeding of hematopoietic stem cell.The health education may raise patient' s related knowledge,thus assisting the successful collection.

Objective To establish characteristic parameters of plural impedance spectra of rabbit whole blood cell.Method The AC impedances of 30 blood samples from the 10 rabbits have been measured with the Agilent 4294A impedance analyzer at frequency range of 0.01～100MHz,then its characteristic data have been analyzed by the Bode plot,the Nyquist plot and the Nichols plot.Results(1)The impedance amplitude and phase angle of rabbit blood cell have a dependence of frequency.(2)The impedance spetroctra of rabbit blood cell have two characteristic frequency:the characteristic 1st frequency(fC1) was 2.58MHz,the characteristic 2nd frequency(fC2) was 5.21MHz.Conclusion The frequency properties of blood cells can be obtained by the analysis of impedance spectroscopy.

Objective To investigate the effects of ischemic preconditioning on pneumocyte apoptosis and the expression of HSFT0 after lung isehemia-reperfusion(I/R) in rats and discuss its possible mechanism of extenu-ating ischemia-repedusion injury. Method Thirtysix male Sprague-Dawley rats were randomly divided into three groups [ sham operation(SO ) group, ischemia-teperfusion(L/R) group, and ischemic preconditioning(IP) group],twelve in each group. Lung croas-clamping was used to build the L/R model. In IP group, three cycles of 5-minute-ischemia + 5-minute-reperfusion were given to the pulmonary artery before the procedure. Sham operation rats had a thoracotomy only. Two hours(or five hours) reperfusion was given to both L/R and IP group. Tenninal-deoxynucleotidyl Transferase Mediated d-UTP Nick End Labeiing(TUNEL) was used to evaluate apoptosis. Expression of HSP/0 in lung was observed by immunohistochemical stain and image analysis. Index of quantitative assessment of histologic lung injury(IQA), wet to dry weight ratio(W/D) were measured. The pathological change of lung tissue was observed under both hght and electron microscopy. Statistical analysis was carried out by One-way Anova. Scheffe test was used for intragroup comparison. Results The apoptosis index and expression of HSP70、W/D,IQA of hng tissue in I/R group were higher than those in the sham operation group (P<0.01). Compared with the L/R group, the apoptosis index and expression of HSP70, W/D, IQA of lung tissue significantly decreased (P<0.01), the levels of expression of HSPTO increased significantly in IP group ( P<0.01 ). The pathological and ultrastructure change of lung tissue was better in IP group than those in I/R group. Condusions Ischemic preconditioning can extenuate lung I/R injury by the possible mechanism of increasing the expression of HSPT0 which inhibits the apoptosis during lung I/R injury.

Objective To investigate symptom characteristics and their their prevalence in terminally ill patients with ovarian carcinoma.Methods A retrospective study was carried out based on clinical data of 98 terminally ill patients with ovarian carcinoma who died in our hospital during January 1995 to December 2004.Fifteen most common symptoms were analyzed with a focus on the followings:symptom incidence,survival time after symptom occurrence,regularity of symptom cluster,and common causes of death.Fifteen symptoms were:pain,cachexia,pleural effusion and ascites,dyspnea,fever,intestinal obstruction,renal failure,bone marrow depression,lung infection,hemorrhage,deep venous thrombosis (DVT),intestinal or pancreatic fistula,mycotic infection,jaundice and emergency conditions.Results (1)The most prevalent symptom was pleural effusion and ascites(63%),followed by pain(60%), cachexia(59%),dyspnea(52%)and intestinal obstruction(49 %).(2)The symptom which lasted longest survival time was mycotic infection(77 days),followed by intestinal or pancreatic fistula(75 days), intestinal obstruction(67 days),pain(60 days)and eachexia(60 days).Symptoms such as bone marrow depression,renal failure,dyspnea and emergency conditions were comparatively critical associated with shorter survival times(14,13,12,7 days,respectively).(3)Terminal symptoms occurred typically in clusters,with 4.9?1.5 symptoms per case.Of 98 cases,84 cases(86%)had 4 or more symptoms,with the median survival time of 63 days from the last day of anti-cancer therapy,and a slow death process.The remaining 14 cases(14%)with 3 or fewer symptoms survived only 25 days,of which 10 cases(71%)died of emergency diseases.The survival time for two groups was significantly different(P

Objective To determine the incidence and risk factors of iatrogenic retinal breaks in eyes undergoing pars plana vit- rectomy for idiopathic macular pucker.Design Retrospective case series.Participant 88 consecutive vitrectomies performed on eyes with idiopathic macular pucker.Method Consecutive vitrectomies performed on eyes with idiopathic macular pucker at Beijing Tongren Eye Center between 2002 and 2006 were retrospectively reviewed.Cases with iatrogenic retinal breaks were recorded and analyzed. Main Outcome Measure Number and location of retinal breaks,and anatomic outcome after surgical managements.Result A total of 88 consecutive vitrectomies were included in the study.Of the 88 eyes,8 eyes had 14 iatrogenic retinal breaks detected,with an aver- age incidence of 9.1%.Peripheral retinal breaks(8.0%)were more common than posterior retinal breaks(1.1%).All peripheral retinal breaks occurred around the selerotomy sites(100%)and the quadrant of predominant hand was involved most commonly(62%).Most of the breaks(88%)were detected during the surgery.All eyes with iatrogenic retinal breaks obtained anatomic retinal reattachment (100%).Conclusion Despite improvements in instrumentation and surgical techniques,iatrogenic retinal break continues to be an im- portant complication of pars plana vitrectomy in eyes with idiopathic macular pucker.This complication tends to occur more commonly at peripheral retina and is mainly selerotomy-related.
