Objective To detemine the effect of autografts of in-vitro cultured corneal limbal stem cells for treating pterygium. Methods A total of 11 cases (12 eyes) with pterygium were treated with autograft of in-vitro cultured corneal limbal stem cells and were followed-up for 6-15 months. Results During the follow-up pterygium recurred in 1 eye (8.33 %) . All of the grafts survived well and no immunological rejection or other complication occurred. Conclusion Autograft of in vitro cultured corneal limbal stem cells is an effective and valuable method to treat pterygium.

0.05) before treatment. After treatment, the hearing thresholds were recovered in 21 ears, signifi-cantly improved in 8 ears, improved in 4 ears and not changed in 2 ears in the DM group. In placebo group, the hearing threshold was recovered in 6 ears, signifi-cantly improved in 9 ears, improved in 15ears and not changed in 6 ears after treatment. There was a signifi-cant difference in the level of hearing improvement be-tween the DM group and the placebo group(x2=13.49, P

To explore th e role of nitric oxide(NO), nitric oxide synthetase (NOS)and prolactin (PRL) in the pathogenesis,progress and prognosis of neonatal hypoxic-ischemia encephalop athy (HIE),plasma NO, NOS and serum PRL were determined by radioimmunoassay(RIA) and colorimetry in 68 newbom infants with HIE and 30 normal control neonates, r espectively. The results showed that the levels of NO, NOS and PRL were signific antly higher in all neonates with HIE than that in the control group (P<0.05).There were in particular more higher levels of NO,NOS an d PRL in infants with either moderate or severe HIE(P<0 .01). It was noticed that the level of PRL was much higher in HIE infants with seizures than that in HIE infants without seizures. There was a positive relati onship between the levels of PRL and the duration of seizure attack( P<0.01). It is suggested that the levels of NO, NOS and PRL is ass ociated with HIE.The determination of these parameters will be valuable clinical ly for the diagnosis, judgement of prognosis and estimation of seizure attack in newborn infants with HIE.

Objective Many studies showed that Ca~(2+) channel blocker could prevent and treat right ventricular hypertrophy(RVH) induced by chronic hypoxia.To further identify the mechanism,we investigated the effect of Ca~(2+) channel blocker on the levels of myocardial calcineurin A?mRNA(CnA?)in RV and plasma nitric oxide(NO),NO synthase and endothelin-1(ET-1) in rats with chronic hypoxia.Methods 30 rats were divided into three groups by randomized block design: treatment group with Amlodipine Besylate ablets [(30 mg?kg~(-1)?d~(-1)),administered via gavage],chronic hypoxia group,and control group.The rats in treatment group and chronic hypoxia group were exposed to normobaric chronic hypoxia [(10.0?0.5)% O_2 ] for 21 days.On the 21st day of experiment,all rats were sacrificed and the hearts were collected for measuring the weight.Blood samples were also drawn from the ventricles for measuring plasma NO,iNOS and ET-1 levels.CnA?mRNA levels in RV were measured by RT-PCR.Results ⑴The RV/(LV+S)、RV/BW ratios were significantly higher in chronic hypoxia group than those of control group and treatment group(P

Objectives To explore the relationships between the current physical exercise behaviors and psychological factors of middle school students,so as to provide scientific evidence for improving health education and carrying out targeted health intervention measures.Methods The Multi-stage stratified sampling and cluster sampling method was adopted to choose 3600 students from 12 junior and senior middle schools in Hangzhou,Wuhan and Xi'an.The date was collected using the adolescent physical exercise behavior-psychological measurement scale(Chinese version).The structural equation model was built to explore the relationships between psychological factors(including the change of strategy,decision balance positive effect,decision balance negative effect and self-efficiency)and physical exercise.Results The change of strategy has biggest effect on physical exercise behaviors,with the standardized direct effect value of 0.344.The standardized direct effect value of decision balance negative effect,decision balance positive effect and self-efficiency were 0.071,0.093 and 0.169 respectively.The negative correlation among the four dimensions was significant statistically.Conclusion Psychological factors have direct effects on the change of the behaviors,and the change of the strategy has the largest impact on physical exercise behaviors of middle school students.The four psychological factors are closely correlated with one another,which is important in formulating middle school sports programs to promote the physical quality of middle school students.

Objective: To explore the echocardiographic cardiac geometric morphology and hemodynamics in premature infants at different gestational age with the inlfuencing factors.
Methods: A total of 150 premature infants and 150 full-term control infants were enrolled in this study. Based on gestational age, premature infants were divided into 3 groups:①(28-32+6 ) weeks,②(33-34+6 ) weeks,③(35-36+6) weeks; and full term control infants were divided into 2 groups:①’(37-38+6) weeks and②’ (39-41+6) weeks respectively. An iE33 Philips ultrasound examination was conducted to measure left ventricular end-diastolic diameter (LVEDD), LVESD, interventricular septum thickness, posterior wall thickness, left ventricular end-diastolic volume (LVEDV), LVESV, stroke volume, LVEF, left ventricular fractional shortening (LVFS), cardiac output, stroke index, cardiac index, left ventricular mass, left ventricular mass index (LVMI), left ventricular relative wall thickness, left ventricular remodeling index (LVRI) and LVEDVI.
Results: With adjusted body surface area, all parameters for cardiac geometric morphology and hemodynamics were similar among different groups,P>0.05. The day-old age (P=0.001), height (P=0.001) and body weight for low weight born infant (P=0.012), for normal weight born infant (P=0.003), for giant infant (P=0.016) were the independent inlfuencing factors for LVMI. The impact of anthropometry and the basic life indexes were similar on LVRI among groups (χ2=42.88,P=0.076), while the covariates were different on LVMI among groups (χ2=123.6,P<0.001).
Conclusion: Cardiac morphology and hemodynamics measured by echocardiography has important clinical meaning for assessing the development and maturity of neonatal hearts in premature infants.

Objective: To determine whether microtubule-associated protein 2 (MAP2) and microtubule-associated protein 1B (MAP1B) could be prognostic biomarkers for patients with pancreatic neuroendocrine tumors (PNETs). Methods:With immunohisto-chemical staining, the expressions of MAP2 and MAP1B were examined in 193 and 120 primary tumors and peritumoral tissues, re-spectively. Then, the relationship between the expression of each protein and clinicopathological characteristics, including prognosis was analyzed. Results:MAP2 and MAP1B were expressed in 88 of 193 (45.6%) and 77 of 120 (64.2%) tumors, respectively. The expres-sion of MAP2 was significantly associated with the favorable overall survival of patients with PNETs (P=0.012). Moreover, MAP2 expres-sion was associated with the improved overall survival in a subset of patients with stageⅡand stageⅢtumors (P=0.017). The MAP1B expression did not correlate with other clinicopathological features and prognosis. Conclusion:MAP2 could be a novel, independent prognostcbiomarker for PNETs.

Anti- N-methyl- D-aspartic acid (NMDA) receptor encephalitis is an autoimmune encephalitis mediated by anti-NMDA receptor antibody. At present, the diagnosis of the disease depends mainly on typical clinical symptoms and detection of specific antibodies in cerebrospinal fluid. Early and timely treatment can curb the disease progression and improve the prognosis of the disease. However, because of the atypical clinical manifestations of patients and long waiting time for antibody detection, early identification is difficult. Imaging equipment is more popular in primary hospitals in China, and it is easier to perform imaging examination for suspected patients in the early stage; therefore, this article aims to review the imaging characteristics and current imaging research progress of anti-NMDA receptor encephalitis in recent years, so as to improve clinicians' understanding and early recognition of this disease.
