AIM:To discuss the application value of retro-mode imaging by F-10 confocal scanning laser ophthalmoscope (cSLO) for detecting drusen in patients with age-related macular degeneration (AMD).METHODS:This was a retrospective case study.During the period of October 2015 to December 2016, 67 patients with unilateral AMD (67 affected eyes and 67 fellow eyes) were included in this study.All patients underwent color fundus photography, optical coherence tomography (OCT) and retro-mode imaging by F-10 cSLO.The features of drusen by color fundus photography, OCT and retro-mode imaging were comparatively observed in the affected eyes of patients with unilateral AMD.Positive numbers of drusen in the fellow eyes of patients with unilateral AMD detected by color fundus photography, OCT and retro-mode imaging were calculated and compared.RESULTS:Retro-mode imaging by F-10 cSLO gave easier to identify images of drusen than color fundus photography and OCT in the affected eyes of patients with unilateral AMD.In the fellow eyes of 67 patients with unilateral AMD, retro-mode imaging showed drusen in 56 cases(84%), color funds photography showed drusen in 36 cases(54%), OCT showed drusen in 48 cases(72%), the difference was statistically significant(χ2=14.31, P<0.05).The positive numbers of drusen detected by retro-mode imaging were significantly higher than color fundus photography, the difference was statistically significant(χ2=13.87, P′<0.0125).There was no statistically significant difference in the positive numbers of drusen detected by retro-mode imaging and OCT(χ2=2.75, P′>0.0125).CONCLUSION:Retro-mode imaging by F-10 cSLO provides a non-invasive technique and should be useful for detecting and monitoring drusen in AMD.

This paper presents a case of post-pancreatitis diabetes mellitus with seriously damaged islet function. The blood glucose level was successfully controlled by continuous subcutaneous insulin infusion ( CSII )therapy both in short and long terms.

Basal rate verification is the process to find and verify the basal rate of continuous subcutaneous insulin infusion (CSⅡ) required for basal glucose metabolism.In the present study,five cases of brittle diabetes were treated by CSⅡ with Insulin Lispro.After doses were adjusted to reach steady blood glucose levels,basal rate verifying tests were carried out.The results showed that the overall level and stability of blood glucose were improved markedly after CSⅡ.Before and after the verification of the basal rate,there was no significant difference in CSⅡ total doses.Basal rates decreased from 50％ of total to 30％ (P＜0.05),and boluses increased to 70％ (P＜0.05).The basal rates during lunch and supper time were reduced by half (P＜0.05),the boluses of lunch and supper were increased 1.5 times (P＜0.05),and square waves were needed to control postprandial blood glucose.These results suggest that the CSⅡ could smoothly control blood glucose level in brittle diabetes without basal rate verification.However,the implementation of the verification could better determine the basal rates for basal glucose metabolism,and thus help to identify diet-related boluses.

Objective To understand the environmental estrogens contamination of tap water and source water. Methods Environmental estrogens in the water samples were concentrated by macroporous adsorption resin H103. The effect of environmental estrogens in concentrated samples was assessed by the recombinant yeast system. Results The results showed that some source water and tap water really contained environmental estrogens. The activity of environmental estrogens in concentrated samples of some source water increased as the volume of concentrated sample increased. The concentrate of 100 ml water sample could show the estrogenic effect. Conclusion Some source waters and tap waters in China have been contaminated by environmental estrogens. Environmental estrogens in source water can not be removed completely by drinking water treatment system of city.

Quality education and innovative ability cultivation of students are a new position in higher education.Exploring exper- iment was applied in teaching of microbiological experiment for enhancing integrative diathesis and cultivating innovative spirit and ability of students.The practice has been proved that learning fervor of students was increased adequately.Unaided operation abili- ty,integrative analysis ability and innovative idea were enhanced,too.Accordingly,teaching quality of microbiological experiment was improved.

Near infrared spectroscopy (NIR) was used to detect trans fatty acids (TFA) in edible vegetable oils quantitatively. And prediction model of TFA was optimized through band selection, pretreatment method, variable selection and modeling method. NIR spectra of 98 edible vegetable oil samples were collected in spectral range of 4000-10000 cm-1 using an Antaris Ⅱ Fourier transform near infrared spectrometer, and the true content of TFA was measured by gas chromatography. First, optimization of waveband and pretreatment method was conducted on original spectra. On this basis, competitive adaptive reweighted sampling (CARS) was used to select important variables that related to TFA. Finally, the prediction models of TFA content in edible vegetable oils were established using principal component regression ( PCR), partial least square (PLS) and least square support vector machine (LS-SVM). The results indicated that NIR spectroscopy was feasible for detecting TFA content in edible vegetable oils, R2 of the best prediction model after optimized in calibration and prediction sets were 0. 992 and 0. 989, and root mean square error of calibration (RMSEC) and root mean square error of prediction ( RMSEP) were 0. 071% and 0. 075% , respectively. Only 26 variables were used in the best prediction model, accounting for 0. 854% of the whole waveband variables. In addition, compared with the full waveband PLS prediction model, the R2 in prediction set increased from 0. 904 to 0. 989, and RMSEP decreased from 0. 230% to 0. 075% . It shows that model optimization is very necessary, CARS method can select important variables related to TFA effectively and immensely reduce the number of modeling variables, so it can simplify the prediction model, and greatly improve the accuracy and stability of prediction model.

OBJECTIVETo study the characteristics of dental arches in the patients with facial asymmetry.

METHODS20 facial asymmetrical patients were chosen as the study subjects. They were 8 boys and 12 girls, aged from 12-year to 16-year old. 20 normal occlusion persons without signs of facial asymmetry were chosen as control. Dental casts were measured by 3-dimension measuring machine. Dental arch asymmetry, coordination between upper and lower dental arch, and dental inclination were measured. SAS 6.03 was used in statistical analysis.

RESULTSThe distance from cuspid and the first bicuspid to the median palatal raphe in the side of crossbite was larger than that of contralateral side in maxilla. The distance from cuspid, bicuspids and the first molar to the midline in the side of crossbite was smaller than that of contralateral side in mandible (P < 0.05). The dental arch width of cuspid and first premolar in maxilla was smaller than that of mandible (P < 0.05) . Significant buccal inclination of the maxillary posterior teeth coupled with lingual inclination of the mandibular posterior teeth was found on the crossbite side. In contrast, significant lingual inclination of the maxillary posterior teeth coupled with buccal inclination of the mandibular posterior teeth was found on the contralateral side (P < 0.05).

CONCLUSIONThe width of upper anterior dental arch was smaller, and the inclination of upper and lower posterior teeth between crossbite side and counterside was different in facial asymmetry patients.

OBJECTIVETo analyze the biologic principle of orthodontic treatment in patients with skeletal Class III malocclusion and open bite.

METHODSEleven pre-adolescent patients with severe skeletal Class III malocclusion and open bite (age range 7 - 9 years old, mean age 8.3 +/- 0.8) were included. All patients were surgical cases but the patients rejected surgery. The treatment methods used were face mask, rapid maxillary expansion occlusal splint and fixed appliance. Lateral cephalometric films were taken before and after treatment. Cephalometric analysis was performed.

RESULTSAfter the treatment SNA changed from (79.0 +/- 1.2) degrees to (81.9 +/- 0.8) degrees (P < 0.01). And the inclination of lower incisors was decreased from (25.6 +/- 2.1) degrees to (20.1 +/- 1.4) degrees when measured to the NB line (P < 0.01). The direction of the facial growth was maintained.

CONCLUSIONSGood orthodontic results could be achieved in patients with skeletal Class III malocclusion and open bite.
