AIM:To discuss the related factors that affected the stability of posterior corneal surface after laser in situ keratomileusis ( LASIK) .
METHODS:About 64 patients (64 eyes) were enrolled. The correlation among the changes in posterior corneal surface 6 month after LASIK, surgery method, corneal flap thickness ( FT ) , ablation thickness ( AT ) , postoperative residual corneal stroma thickness ( RCST ) , preoperative thinnest corneal thickness ( CT ) , flap thickness/preoperative thinnest corneal thickness ( FT/CT ) , ablation thickness/preoperative thinnest corneal thickness ( AT/CT) , postoperative residual corneal stroma thickness/preoperative thinnest corneal thickness ( RCST/CT) , anterior and posterior preoperative corneal height, the difference of the forward shift in posterior corneal surface ( diff value ) of preoperative and preoperative intraocular pressure were analyzed.
RESULTS: The changes of diff value between preoperative and postoperative were related with diopter (r=0.419, P=0.014), AT (r=0.394, P=0.023), AT/CT (r=0.501, P=0.004), Diff value of preoperative (r=0.501, P=0. 004), RCST (r=-0. 385, P=0. 033) and RCST/CT (r=-0. 401, P=0. 025). The changes of height value from posterior corneal surface between preoperative and postoperative were related with diopter (r=0. 520, P=0. 002), AT (r=0.504, P=0. 003), AT/CT (r=0. 442, P=0. 013), Diff value of preoperative (r=0. 624, P=0. 000) and RCST/CT (r=-0. 394, P=0. 028).
CONCLUSION: AT, RCST, AT/CT, RCST/CT and diff value of preoperative should be the key index that predicted the stability of posterior corneal surface after LASIK,the further research will give the range of safety value.

OBJECTIVE:To study the effect and mechanism of tandospirone citrate (TC) on blood pressure in spontaneously hypertensive rats (SHR). METHODS:SHR were divided into model group,positive control group (Levamlodipine besylate tab-lets,2.5 mg/kg),TC high-dose,medium-dose,low-dose groups(TC capsules,40,20,10 mg/kg),8 in each group. Other 8 nor-mal rats were chosen as normal control group. The rats were intragastrically administrated medicines,once a day,for 28 d. Systolic blood pressure(SBP)before first administration and after 0.5,1,1.5,2,3,4 h of administration in each group were measured, and SBP after 1 h of administration were measured once every 7 d. After last administration,nitric oxide(NO)content in serum, endothelin,renin,angiotensin Ⅱ(Ang Ⅱ) and norepinephrine (NE) contents in plasma were detected. RESULTS:In single ad-ministration,compared with model group,SBP in 0.5,1 h in positive control group and TC groups after first administration were obviously decreased (P<0.05 or P<0.01),then SBP were obviously decreased only in positive control group and TC high-dose group (P<0.05 or P<0.01). In multiple administration,compared with model group,SBP in 7th,14th,28th day of administra-tion in positive control group and TC high-dose,medium-dose groups were obviously decreased(P<0.05 or P<0.01). Compared with model group,NO content in serum in positive control group,TC high-dose group were obviously increased;endothelin,re-nin,Ang Ⅱ and NE contents in plasma were obviously decreased (P<0.05 or P<0.01). Compared with positive control group, NO content in serum in TC groups was obviously decreased;endothelin,renin,Ang Ⅱ and NE contents in plasma were obviously increased in TC medium-dose group (P<0.05). CONCLUSIONS:TC can obviously decrease the blood pressure of SHR. The mechanism may be associated with adjusting the balance of NO and endothelin,and decreasing renin,AngⅡand NE contents.

AIM: To investigate the change of myopic choroidal neovascularization treated by ranibizumab and evaluate their value in monitoring the effect of anti-vascular endothelial growth factor ( VEGF) therapy. ·METHODS: The study enrolled 30 patients ( 30 eyes ) diagnosed with myopic choroidal neovascularization. All affected eyes were treated with intravitreal ranibizumab 0. 05mL ( 10mg/mL ). Best corrected visual acuity ( BCVA ) , non-contact tonometer, ophthalmoscope, fundus fluorescein angiograph ( FFA ) and OCTA were evaluated monthly until 6mo. The changes of BCVA and central macular thickness ( CMT) were compared at 1, 3 and 6mo after treatment. ·RESULTS:All patients received an average of 1. 70±0. 65 injections. BCVA was 0. 96 ± 0. 17 ( LogMAR ) before therapy, and BCVA 1, 3 and 6mo after treatment respectively improved by 0. 23 ± 0. 09, 0. 34 ± 0. 07, 0. 38 ± 0. 11. The differences were significant ( t=5. 461, 8. 191, 8. 894; P<0. 05 ). Mean CMT decreased form 281. 07 ± 13. 72μm to 261. 33 ± 13. 13μm, 243. 47 ± 16. 65μm, 234. 73 ± 17. 52μm respectively 1, 3 and 6mo after treatment, showing significant differences (t=12. 007, 13. 360, 9. 531;P<0. 05). OCTA revealed a progressively smaller vascular lesion and reduction in capillary density. · CONCLUSION: Intravitreal ranibizumab for CNV secondary to pathologic myopia is effective and safe;OCTA is a noninvasive and time-saving new technology, and it also is a promising tool for clinicians to make preliminary diagnosis and assess treatment efficacy in the follow-up visits.

Objective: To investigate the effect of taurine on learning and memory impairment, cytokines secretion in rats intrahippocampally injected with ?-amyloid (A?) 1-40. Methods: SD rats were randomly divided into control group, A? injected group, taurine (0.3g/kg?d, 0.6g/kg?d) groups. The rats were fed with taurine for 7 days, and then subjected to bilateral intrahippocampus injection of A?1-40 or vehicle. Two weeks later, all rats performed Morris water maze test. The contents of IL-6, TNF-? were checked by way of radio-immunity assay for hippocampus samples. Results: Compared with A?model group, the escape latency and distance were significantly reduced in taurine (0.6g/kg?d) group; the ratio of swimming distance in the target quadrant to that in the whole pool of the probe trial; the content of cytokines of IL-6 and TNF-?in hippocampus were reduced significantly. Conclusion: Taurine can effectively attenuate the cognitive dysfunction caused by A?1-40 in rats. The reduced cytokines content in hippocampus might contribute to this effect.

OBJECTIVE: To study the tongue tissue blood oxygen saturation measurement for evaluating tongue manifestation of blood stasis syndrome, and to explore its correlation with blood rheological disorder in a rat model of acute transient brain ischemia. METHODS: Twenty-eight SD rats were randomly divided into sham-operated group and ischemia group. Middle cerebral artery occlusion was induced by thread in rats of the ischemia group. Tongue tissue blood oxygen saturation, neurological severity score and the changes of blood viscosity, red blood cell deformity, thrombin time and fibrinogen in the rats were measured after 24-hour reperfusion. RESULTS: Blood viscosity and the content of fibrinogen in the ischemia group were significantly higher than those in the sham-operated group. Red blood cell deformity, thrombin time and tongue tissue blood oxygen saturation in the ischemia group were decreased as compared with the sham-operated group. There was a positive correlation between red blood cell deformity and tongue tissue blood oxygen saturation. CONCLUSION: Tongue tissue blood oxygen saturation is a good measurement for evaluating blood stasis in a rat model of focal cerebral ischemia, and this model can be used as a rat model of stroke with blood stasis syndrome.

Objective To discuss the worthiness of real-time three-dimensional echocardiography in researching normal fetal heart ventricle growth and systolic function. Methods End-systolic volume(EDV),end-diastolic volume(ESV), struggle volume(SV) and ejection fraction(EF) of 54 normal fetal were acquired from 3-D data by Qlab software. The relation between ventricular growth with pregnant week was analysed and the difference of the volume and systolic function between left ventricle with right ventricle were compared. Results Ventricular volume of normal fetal heart (EDV,ESV,SV) were all increased with the gestational ages,there was linear relativity between them,while EF was not increased with pregnant weeks,there was no linear relativity between them. There was no statistics difference on EDV and ESV between left ventricle and right ventricle, while there was statistics difference on SV, EF between them. Conclusions The image of fetal endocarium could be derived clearly by real-time three-dimensional echocardiography, which help to get fetal heart ventricular volume and to study fetal heart growth and function.

Objective To explore the clinical feature,diagnosis and treatment of postoperative chylothorax after congenital cardiac surgery.Methods From Jan.2000 to Jan.2008,36 consecutive infants following cardiac surgery were diagnosed postoperative chylothorax.Age at operation ranged 6 days to 4 years.Weight ranged 3.5 kg to 17.0 kg.Indications for cardiac surgery were:tetralogy of Fallot 18 cases,complete atrioventricular septal defect 5 cases,double outlet of right ventricle 4 cases,complex heart defect for Fontan operation 4 cases,coarctation of the aorta 2 cases,total anomalous pulmonary venous drainage 2 cases,patent ductus arteriosus 1 case.Chylothorax occurred in right side was 32 cases,in left side 3 cases,bilateral side 1 case.Diagnostic time for chylothorax was postoperative 1-10 d.Results Thirty-four cases were treated conservatively with success(34/36,94.44%).Only 2 cases needed surgical treatment.The chest drainage volume before con-servative treatment was 22-60 mL/(kg?d)[mean 40.82 mL/(kg?d)].The mean duration of chylous drainage was 15 d(ranged 7 d to 42 d).There was no death in hospital.Two children had sepsis.The cases were followed up 2 weeks-7 years.One newborn was abandoned because of the other reason after discharge.There was no recurrence of chylothorax.Twenty-two cases were still in low-fat diet.Conclusions The chylothorax following operation of congenital heart disease should be noticed and early diagnosed.The initial treatment is conservative,but surgical treatment ought to be considered if the conservative management is unsuccessful.J Appl Clin Pediatr,2009,24(1):70-72
