AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

AIM: To study the clinical characteristics of corneal perforation ( CP) .
METHODS:A retrospective analysis in July 1995 to July 2010 the First Affiliated Hospital of Fujian Medical University diagnosed CP 72 patients ( 72 eyes ) , clinical characteristics of all the patients were analyzed.
RESULTS: The incidence of corneal ulcer perforation rised year by year, the morbidity of male and female was 17:7, the onset age focused on 48 years old. Of 23 industrial workers ( 32%) with clear history of trauma, pathogeny identification results:top two:fungal infection and Acanthamoeba keratitis. A using history of glucocorticoid was found in 10 cases.
CONCLUSION:There are plenty of primary causes of CP such as traumas, fungal infection, Acanthamoeba keratitis, eroded keratitis, etc. CP happens in middle-aged males in Fujian province, most traumas are the causes, the main pathogenic bacteria is fungal infection.

Objective To explore the relationship between cough variant asthma (CVA) and mycoplasma pneumoniae (MP) infection.Methods Fifty children with CVA were chosen as the experimental group at random,and 50 children with acute upper respiratory infection,who went to the hospital in the same time and with similar age,were chosen as control group.The MP-IgM of children in both groups were tested by the granule agglutinating method.Results Significant difference (? 2=9.013 P

Objective To investigate the effect of exogenous hydrogen sulfide (H 2 S) on H2 S concentration and cystathionine β-synthase (CBS) expression in hippocampus in a rat model of vascular dementia (VaD). Methods A rat model of VaD was induced by using the modified four -vessel occlusion. The rats were divided into sham operation, model, low -dose and high-dose NaHS groups using the random number table method. They were further redivided into one day, seven -day, and 30-day subgroups according to the time after modeling. After modeling respectively, NaHS 30 μmol/kg and 100 μmol/kg were injected intraperitoneally every day in the low -dose and high-dose NaHS groups. The normal saline was injected intraperitoneally every day in the sham operation group and the VaD model group. Morris water maze test was used to evaluate the learning and memory ability of the rats. The expression of CBS in hippocampus was detected by real-time fluorescent polymerase chain reaction. Western Blotting was used to detect expression of CBS protein in hippocampus. Results Morris water maze test showed that the escape latencies of the model group, low -dose and high-dose NaHS groups were prolonged significantly compared with the sham operation group (P <0.05); the times of crossing the platform were decreased significantly compared with the model group (P <0.05); and the escape latencies were shortened significantly in the low -dose and high-dose NaHS groups compared with the model group ( P <0.05). The H2 S content in hippocampus was decreased significantly in the model group, low -dose and high-dose NaHS groups compared with the sham operation group, but the low -dose and high-dose NaHS group was significantly higher than that in the model group (all P <0.05). The expression of CBS mRNA and protein in the model, low -dose and high-dose NaHS groups was significantly lower than that of the sham operation group (all P < 0.05), and there was no significant difference between the low -dose and high-dose NaHS groups and the model group. Conclusions Exogenous H2 S may improve the learning and memory ability of the VaD rats. It may be associated with the increased H2 S content in hippocampus. However, it has no effect on CBS expression.

Objective To investigate whether functional electrical stimulation (FES) can improve the expression of proteins in the NMDAR1-pGLuR1 pathway so as to promote the recovery of motor function and sensation after stroke.Methods Eighty-one Wistar rats were used to make a photochemical brain model of local ischemia.Rats were randomly assigned into a sham, placebo stimulation or FES group.Rats in the placebo and FES groups had local ischemia induced in the M1 zone of the brain using the photosensitive dye Bengal rose.It was administered intravenously and a laser beam was then stereotactically positioned on the skull.The rats in the FES groups were stimulated for 30 minutes (10 minutes on, 10 minutes off, then 10 minutes on).The placebo group's treatment was similar, but without the electric current.The rats in the sham group received no intervention.The cylinder test and the adhesive-removal test were used to test the rats' motor function and sensation before the operation and before they were sacrificed.Cohorts were sacrificed after 3, 7 and 14 days of intervention.NMDA receptor and AMPA receptor were detected in the peri-ischemic cortex using western blotting.Results After 7 and 14 days the index of forelimb motor function in the cylinder test of the FES group was significantly better than that of the placebo group.The average adhesive-removal time of the FES group was also significantly faster compared with the placebo group.After 7 days the average expression of NMDAR1 in the FES group was significantly higher than in the placebo group.The average expression of GluR1 and pGluR1 in the FES group was significantly higher than in the placebo group after 14 days.Conclusion Functional electrical stimulation can improve motor function after ischemia through the NMDARAMPAR signal pathway, at least in rats.

Objective ST-T complex change, which represents the ventricle repolarization phase, is the main clinical indicator in detecting myocardial ischemia (MI) based on electrocardiogram (ECG) signals.However, its feature point location is not accurate due to interferences. In this paper, a new approach about myocardial ischemia analysis was proposed based on QRS complex. Methods QRS complex, representing the ventricle depolarization process, was used to analyze myocardial ischemia, and some parameters were extracted synthetically in time domain. Then they were used for statistical analysis of myocardial ischemia states and non-myocardial ischemia states. Results Five parameters had significant differences after verification of Non-MI signals in MIT-BIH database and MI signals in long-term ST database (LTST) and they were: QRS upward and downward slopes, transient heart rate, R angle and Q angle in a triangle QRS. Conclusion Five parameters extracted from QRS complex had significant differences. The proposed method provides an important basis for myocardial ischemia detection.
