METHODS:A retrospective case series were studies. Totally 2 040 cases ( 4 080 eyes ) from January 2010 to October 2012 in our hospital were collected, the corneal flap was observed using lamp microscope after LASIK within 30min. Corneal flap dislocation, corneal flap strial and intraface debris were examined after operation, the effective treatment and controlled measure should be taken for these complications.
RESULTS: Postoperative complications were corneal flap dislocation 102 eyes (2. 5%), corneal flapstriae 95 eyes (2. 33%), interface debris 105 eyes (2.57%). No failure case was seen. There had no corneal flap-related complications, which seriously impact the visual quality after the surgery.
CONCLUSION: Carefully postoperative examination at the first - time is an effective way to manage some complications of post - LASIK. Thus promoting the diagnosis and treatment of post-LASIK complications.

Objective To explore the reasons for disharmony between medical staff and medical staff because of electronic clinical ordering,to specificate electronic medical order in ward in order to create a harmonious relationship between doctors and nurses. Methods The methods of qualitative research conducted in-depth interviews of 12 medical staff, field recordings and transcripts, and the method of content analysis were used. Results Two themes were sublimated:medical staff reasons:lack of communication between the medical staff;new doctors didn't have a good command of medical norms of specialist electronic orders; on the responsibility of checking the doctor's advice problems may lead to potential adverse events occurrence. System equipment reason: the electronic doctor's advice system set up the problem; the office computer quantity is insufficient. Conclusions Nonstandard electronic medical management leads to the disharmony of health care. It is suggested to standardize the management of electronic medical advice by implementation of the responsibility to avoid medical coupling errors. The health care workers need to strengthen communication, mutual understanding and forgiveness, in order to create a harmonious medical environment.

Objective To evaluate the diagnostic value of tissue Doppler imaging (TDI) in classification of fetal arrhythmias, and conclude characters of each type of arrhythmias by analyzing wave forms of TDI. Methods Fifty-five fetuses suffered arrhythmia were included in study group. By comparing the results with control standard(M and PW), the sensitivity, specificity and reliability of TDI in diagnosis of fetal arrhythmias was calculated. At last, the character of waves by TDI of each type of arrhythmia was concluded. Fetal kinetocardiogram was made to identify the origin of arrhythmias. All cases were asked to perform electrocardiography and echocardiography examination after birth. Results The sensitivity, specificity and reliability of TDI was 98%, 100% and 100%, respectively. The character of atrioventricular waves and kinetocardiogram of 8 types fetal arrhythmias were conclude. Conclusions TDI has great value in classification of fetal arrhythmias.

Objective To provide basis for routine fetal cardiac screening by comparing the ultrasound detection rate of fetal heart defects between the high-risk and low-risk population.Methods According to the questionnaire about maternal risk factors,all 7165 pregnant women were divided into two groups.The high-risk group included 2147 cases and the remained 5018 were considered as low-risk population.Routine fetal heart screening was performed by the four-chamber view,left and right outflow tract views.If some cardiac malformations were found,the detailed fetal echocardiography would be performed.Both the detection rate of fetal cardiac defects and distribution of the relevant risk factors were analyzed.Results Ninty-five(1.33%)cases of congenital heart disease were found in our study,32(1.49%)cases from highrisk group and 63(1.26%)cases from low-risk group.No significant was found between the two groups (X2=0.635,P＞0.05).Karyotyping were performed prenatally in 23 of 95 fetal congenital defects cases by cordocentesis and chorionbiopsy,and 11(47.83%)cases of concomitant chromosomal abnormality were found.Conclusions Routine fetal screening for congenital fetal diseases should be performed in non-selected population for the similar detection rate of fetal defect in high-risk and low-risk group.

Objective:To explore whether apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin can be cross-presented by dendritic cells(DCs) and enhance immune responses.Methods:DCs were induced from peripheral blood monocytes cells by GM-CSF/IL-4 for 6 d,then they were stimulated with either apoptotic ovarian cancer HO8910 cells,frozen-thawed HO8910 cells or control cells for 4 h.Their surface markers and phagocytotic ability were detected by flow cytometry and confocal microscopic scanning assay,respectively.DCs of different groups were cultured with CD8+ T cells isolated by magnetic cell sorting,and the ability of DCs to activate CD8+ T cells was evaluated by 3H-TdR,the activity of CTL to kill tumor cells was evaluated by LDH.Production of IFN-? by CD8+ T cells was measured by ELISPOT.Results:Apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin could be phagocytized by DCs,which subsequently promoted the maturation and antigen presenting ability of DCs.Apoptotic ovarian cancer cells implused DCs significantly promoted proliferation of CD8+ T cells compared with that of control cells(P

Abstract?AIM: To analyze the clinical effects of partial rectus muscle transportation procedure for paralytic strabismus due to single rectus muscle paralysis.?METHODS:The conditions of 22 patients (25 eyes) who underwent partial rectus muscle transportation procedure for paralytic strabismus due to single rectus muscle paralysis were retrospectively reviewed. The following data were analyzed:1 ) the angle of deviation of primary position; 2 ) the presence of diploma in the primary position;3) the presence of compensatory head posture;4) the motility of the affected eye.All of the patients attended 6mo postoperative follow-up examinations.?RESULTS: According to the results of examinations before and during operation, different operations were performed:2 eyes were treated with partial rectus muscle transportation, 20 eyes were treated with recession of antagonistic muscle of paralytic rectus muscle combined with partial rectus muscle transportation, 3 eyes were treated with recession of antagonistic muscle, partial rectus muscle transportation and recession of yoke muscle.Twenty patients were orthotropia in the primary position, the diploma and abnormal head posture were eliminated. Two patients with binocular lateral rectus muscles paralysis were in mild undercorrection which were resolved by wearing 8△and 10△prisms respectively.
