Objective: To explore the feasibility of observing hemodynamics on ischemia/reperfusion(I/R) rat heart model in vivo by studying the changes of hemodynamics,myocardial zymogram and electrocardiogram. Methods: Twenty SD rats were randomly divided into 2 groups(n=10)(IR group and control group).The left anterior descending coronary artery was ligated or left untouched,a catheter was put into the left ventricle to trace the pressure change index and peak pressure of left ventricle,and to record ST segment changes of ECG.At the end of experiment,the levels of myocardial zymogram were determined.The results of two groups were compared. Results: Compared with control group,IR group showed reduced dp/dt max,declined LVSP,raised ST segment in ECG,and elevated myocardium zymogram. Conclusion: Our I/R rat heart model in vivo is feasible and stable to explore the cardiac hemodynamics.

Objective To investigate the hypothesis that food allergy in infants may be associated with variation in their intestinal microflora. The formation of intestinal microflora in healthy infants and changes in food allergic infants were detected.Methods 16S rRNA gene sequences specific for bifidobacterium, lactobacillus and escherichia coli in fecal were quantitatively detected by real-time PCR. The three fecal floras were assessed in 71 healthy infants and 100 infants with food allergy. Results After birth,there were bifidobacteria colonized in infantile intestine,then the number increased rapidly up to 5 times at the sixth month, which was always the preponderant flora. Lactobacilli was also presented in infantile intestine 1 month after birth and augment gradually. The number of Escherichia coli was less than bifidobacteria and lactobacilli and appeared to decline during the early infants. The number of bifidobacteria and lactobacilli in the infants with food allergy were markedly less than that in the healthy infants, but escherichia coli was significantly more than that in the healthy infants.Conclusions During the first year of life,the intestinal microflora in infants is in a developing process. Compared with the healthy infants,bifidobacteria and lactobacilli decrease, but escherichia coli increase in the food allergic infants.These results indicate that the probiotics may be benefit to the prevention and treatment of food allergy.

OBJECTIVETo observe the effect of external application of Zhuangshenling Recipe (ZR) combined with Western medicine (WM) on the heart function of chronic heart failure (CHF) patients of Xin-Shen yang deficiency, interior retention of water-fluid syndrome (XSYDIRWFS).

METHODSTotally 140 CHF patients of XSYDIRWFS were randomly assigned to two groups, the treatment group and the control group, 70 in each group. All patients received WM therapy. Those in the treatment group were applied with ZR at Xinshu (BL15) and Shenshu (BL23), while those in the control group were applied with placebos at Xinshu (BL15) and Shenshu (BL23). The therapeutic course for all was 12 weeks. The integrals of TCM syndrome, grading of cardiac function, brain natriuretic polypeptide (BNP), and 6 min walking distance were observed before and after treatment.

RESULTSAfter twelve weeks of treatment, the effective rate of improved grading of cardiac function, the total effective rate of TCM syndrome efficacy, and the BNP level were obviously better in the treatment group (P < 0.05). There was no statistical difference in 6 min walking distance between the two groups (P > 0.05).

CONCLUSIONExternal application of ZR combined with WM could improve the heart function of CHF patients of XSYDIRWFS.

AlM: To evaluate the clinical effect of 200g/L protein-free calf blood extract eye gel for corneal epithelial defect.METHODS: One hundred and sixty - eight cases of corneal epithelial defect ( 58 cases with herpes simplex keratitis; 24 cases with chemical injury; 85 cases with pterygium operation injury ) were randomly divided into two groups: 84 eyes were treated with protein-free calf blood extract eye gel; 84 cases were treated with basic fibroblast growth factor eye gel ( bFGF ) . The bFGF and protein-free calf blood extract eye gels were used 4 times a day. The treatment course was 7d. Epithelial defect restoration, local symptom and sign were observed.
RESULTS: The difference between pre-treatment and post-treatment was significant ( P<0. 01 ) in the two groups. The effect of protein-free calf blood extract eye gel (83. 3%) group was prior to that of bFGF (69%) for corneal epithelial defect. The effective rate of protein-free calf blood extract eye gel in the herpes simplex keratitis, chemical injury and pterygium operation injury was 72. 4%,69. 2% and 95. 2%. Localized stimulus and adverse reaction of all over the body were not been observed.
CONCLUSlON: Protein-free calf blood extract eye gels is valuable and safe for corneal epithelial defect.

To observe the morphology of corneal endothelial cells after femtosecond laser in situ keratomileusis ( Femto-LASlK) .METHODS:From May to September in 2013, 88 eyes of 45 patients with myopia who accepted Femto-LASlK were enrolled in this study. The morphology of central corneal endothelial cells was measured by a non-contact corneal endothelial cell analyzer before, 1mo and 1a after surgery. The number, density, average size, size standard deviation, size coefficient of variation and hexagonality of the corneal endothelial cells were observed. All the measurements were analyzed by statistical analysis.RESULTS: All patients underwent operation smoothly, and no complication was observed during and after surgery;One month after surgery, the endothelial cell density (ECD) was 2815. 34±297. 07/mm2, which had a 2. 64% decrease compared with preparative ECD (t=4. 60, P= 0. 00), there was no statistical significance between ECD measurements of 1mo and 1a after surgery ( P>0. 05 ); One month after surgery, the size standard deviation ( SSD ) was 118. 47 ± 31. 58μm2 , which increased significantly compared with the preoperative SSD(t=-3. 87, P=0. 03), there was no statistical significance between SSD measurements of 1mo and 1a after surgery ( P>0. 05 );After surgery, the number, hexagonality, average size and size coefficient of variation of the corneal endothelial cells didn't change statistically(P>0. 05).CONCLUSlON: ln the early period after Femto-LASlK, the ECD decreased slightly, however this kind of surgery did not have significant harm to the function of corneal endothelial cells, and the surgery didn't cause the progressive loss of corneal endothelial cells.

AlM: To explore the judgment of pattern reversal visual evoked potential on visual function and injured part of children with spastic cerebral palsy.METHODS: There were two groups in this study. 30 children with spastic cerebral palsy ( quadriplegia: 15, diplegia:15) were selected as observation group, while 30 normal children were selected as control group with randomized controlled trial. The changes of half-view and full- view incubation period and amplitude were observed by pattern reversal visual evoked potential.RESULTS: Full-view pattern reversal visual evoked potential: the P100 incubation period of the observation group was 113. 55 ± 8. 14ms, and the P100 amplitude was 23. 08±15. 41μV. The P100 incubation period of the control group was 105. 05 ± 5. 58ms, and the P100 amplitude was 31. 65±7. 37μV. From the comparison on P100 incubation and P100 amplitude between two groups, the difference was statistically significant ( P<0. 05 ) . P100 incubation period of the spastic diplegia of full-view pattern reversal visual evoked potential was 112. 73±7. 22ms, and the P100 amplitude was 21. 03±12. 17μV. P100 incubation period of the spastic quadriplegia was 114. 37 ± 9. 02ms, and the P100 amplitude was 25. 14 ± 18. 06μV. From the comparison on P100 incubation and P100 amplitude between two groups, the difference had no statistically significance (P>0. 05). Compared to the control group, each eye and each view latency of observation group were higher, the difference was statistically significant ( P<0. 05). The change of the incubation period of the full-view and half - view pattern reversal visual evoked potential took place in the lesion of the visual pathway:including optic neuropathy, some optic nerve lesion, lesion after optic chiasma, and optic chiasma lesion. Among them, the lesion after the optic chiasma was the most common.CONCLUSlON:Pattern reversal visual evoked potential can help people to understand the visual impairment and injury of children with spastic cerebral palsy in order to identify the abnormal children and early intervention.

Abstract?AIM:To evaluate the pupil light reflex in patients with primary open angle glaucoma, and to investigate the relation between pupil and visual field defect.?METHODS:From July 2014 to October 2015, 115 eyes in 86 patients with primary open angle glaucoma and 23 eyes in 16 healthy individuals were continuously enrolled in this study.All the subjects received comprehensive eye examination, visual field examination ( Humphrey, SITA Standard 24-2 ) and dynamic pupil measurement ( MonCV3 Metrovision) .According to the visual field and the Glaucoma Staging System, the patients with glaucoma were divided into 5 subgroups: stage 1, stage 2, stage 3, stage 4 and stage 5. The parameters of pupillary light reflex were as follows: pupil diameter ( minimum, maximum ) , latency and duration of contraction, latency and duration of dilatation, contraction amplitude, contraction and dilatation speed, and percent of pupil contraction ( PPC ). SPSS 19.0 statistical software was used to analyze the measurement results.?RESULTS:The control group significantly differed from the stage 4 subgroup ( P=0.032 ) and stage 5 subgroup (P=0.014) in terms of minimum pupil diameter; there was significant difference in the pupil contraction speed between groups ( F =648.675, P <0.01 ), and the contraction speed in stage 5 subgroup was significantly lower than those in the other subgroups and control group (P<0.05); the control group significantly differed from the stage 3, stage 4, and stage 5 subgroup in terms of PPC ( P<0.05 ).Pupil contraction speed, PPC and minimum diameter showed correlation with the stages of glaucoma.?CONCLUSION:Pupil contraction ability in patients with primary open angle glaucoma was impaired, and the degree of impairment is related with the degree of visual field defect.

Purpose Ovarian dysgerminoma has no specific symptoms or physical signs, which is thus prone to misdiagnosis before treatment. This paper aims to investigate CT and MRI clinical features of ovarian dysgerminoma, so as to provide an accurate basis for its clinical treatment and also improve patients'' life, quality.Materials and MethodsThe CT and MRI data of 13 patients with ovarian dysgerminoma proved by pathology were retrospectively analyzed. Three patients underwent plain and enhanced CT scan, 6 took plain and enhanced MRI scan on T1WI and T2WI with different angles of views, and 4 other patients were performed both CT and MRI scan.Results①Twelve patients had single lesions, and 1 was bilateral multiple ones. The diameter of the lesions ranged from 5.5 cm to 16.5 cm, with mean of (9.5±3.8) cm; in terms of pathological type, 11 belonged to single type and 2 were mixed.②The CT results showed that 6 were solid mass and 1 was cystic. On enhanced CT scan, 6 cases showed heterogeneous light-to-moderate enhancement, 4 had tumors with significantly enhanced blood vessels, and 1 showed heterogeneous significant enhancement at arterial phase; all cases presented continuous enhancement at venous phase.③The MRI manifestations demonstrated 8 were with solid mass, which displayed iso- or slightly hypointense signal on T1WI, and iso- or slightly hyperintense signal on T2WI. The enhanced scan showed that 5 cases had heterogeneous mild enhancement, 3 had moderate enhancement, and 4 were seen with tortuous tumor vessels at arterial phase; all displayed continuous enhancement at venous phase. In the one case of cystic mass, solid component had moderate enhancement at arterial phase and continuous enhancement at venous phase. In another case of multilocular cystic mass, the tumor separate and cyst were significantly enhanced at arterial phase, and were continuous enhanced with hyperintense at venous phase.Conclusion Ovarian dysgerminoma tumors present features such as large lesions with clear boundaries. Tumors of single type are likely to be solid mass with central necrosis; the plain CT scan shows isodensity; the plain MRI scan mainly shows isodensity on T1WI, and iso- or slight hyperintensity on T2WI; the enhanced scan presents slight to moderate enhancement. Tumors of mixed type demonstrate cystic mass; the solid and separate parts are significantly enhanced. The comprehensive analysis of imaging features of ovarian neoplasms could help to make a correct diagnosis before surgery.
