November and December were the peak reporting periods, and schools and preschool institutions were the main places where these events occurred.

Background Image clarity during near work is influenced by several factors,such as accommodative lag,pupil size and monochromatic aberrations.Since image clarity during extended reading at near distance has been cited as a possible inducement of myopia in childhood and a possible difference between myopic and emmetropic people throughout life,it is important to examine these factors in myopic and emmetropic myopic juvenile during reading at near distance. Objective The aim of this study was to investigate the relationships among wavefront aberrations,accommodative response and pupil size in early onset and progressive myopes eyes under the different reading status and explore the possible mechanism of the development of myopia as well. Methods Fiflyseven subjects aged from 12 to 16 years were enrolled and grouped as emmetropes,the onset of myopes and progressive myopes.Reading material were Chinese novels presented by rapid serial visual presentation at a distance of 25 cm. Accommodative response and pupil size were recorded by a Grand Seiko WV-500 autorefractor.The Image J software was used to calculate the pupil diameter.Wavefront aberrations were then measured with a WASCA wavefront analyzer. Results Aberrations and accommodative response showed large inter-subjeet variability.With accommodative stimulus of 4 diopter,the accommodative lag in the early-onset of myopes group and progressive myopes group were ( 1.72 ±0. 53) D and ( 1.74 ±0. 44) D, showing larger value in comparison with ( 0. 96 ±0. 55) D of emmetropes group( t＝4.25 ,t=4.47 ,P<0. 001). However,there were no significant differences in accommodative lag between the early-onset of myopes group and progressive myopes group( t = 0. 18, P>0. 05). The mean value of pupil diameter, total RMS value, high-order RMS value, spherical aberration and coma were all significantly reduced with the stimulus varied from 0 D to 4 D( P<0. 01). However,none of the pupil sizs,total RMS value,high-order RMS value,spherical aberration and coma had significant difference among different refractive groups( P>0. 05). Conclusion The early-onset of myopes and progressive myopes had larger accommodative lag. The lower sensitivity to defocus at near reading distance,inducing the larger accommodative lag and hyperopic defocus may be linked to the developing myopia.

Background Epidemiologic studies found that the incidence of myopia is higher in Hong Kong and Taiwan regions of China than that of the mainland.So whether the general reading words with traditional Chinese characters and simplified characters is associated with myopia deserves attention.Objective This study was to test the accommodative responses and the regression levels of nearwork-induced transient myopia (NITM) induced by traditional complex Chinese characters and modern simplified ones in the same size,and to explore the differences and inherent relationship of the accommodative regulations based on the structures of the two types of Chinese character in causing reading triggered myopia.Methods Twenty two volunteers aged 24-29 years were included in this study with informed consent.The corrected vision of both eyes from each subject was ≥ 1.0 with a mean spherical equivalence of (-1.86±2.34)D.Accommodative response was tested with 4 different reading texts using the rapid sequence visual presenting model with the GRAND SEIKO-WV5500 infrared autorefractor,and this procedure was performed after full correction of refractive error.An initial test of looking at a certain distance was performed (as baseline),and then the subjects read intensively at the targets for 10 minutes at 33 cm to calculate the accommodative responses.After a 10 second pause,the ocular refractive status was obtained exactly at 15 seconds,20 seconds.The one-way ANOVA method was used to determine the effects of the different font types and sizes on the adjustive responses and the causation of NITM.Results Accommodative response induced by simplified and traditional Chinese characters showed an accommodative lag of (1.11 ±0.38),(0.95 ±0.43),(1.18 ±0.33) and (1.06±0.28) D,showing a significant difference among the 9 pt and 12 pt simplified and traditional Chinese characters (F =1.62,P =0.19),and significantly different accommodative lag values between 12 pt simplified characters and 9 pt traditional characters was found (t =5.56,P =0.02).NITM induced by the four different targets were (-0.45 ±0.45),(-0.47 ±0.46),(0.45 ±0.82) and (-0.46±0.78) D in the 4 types of characters,without a significant difference among them (F=0.01,P =0.99).Conclusions Near-distance reading causes accommodative lag regardless of the type of reading texts.The target demonstrated stimuli spatial frequency and font size play an impact on accommodative responses.NITM appears when one reads simplified or traditional Chinese for 10 minutes.The accommodative lag and NITM trend might be responsible for the onset or regression of myopia,yet it is not supportive for the hypothesis that reading traditional Chinese causes more strain since there is no difference between the two.

Background Researches showed that as the non-optical factors,cognitive has certain influence on the regulating system.So accurately experimental design is one of the key steps that evaluates the non-optical factors on regulating system.Objective The present study was to investigate the influence of presenting pattern of target and watching way on the level and amplitude of accommodative fluctuate and to analyze the effect of focus gaze of cognitive on regulating system and the relationship between focus gaze condition under near work and the development of myopia.Methods This study complied with Declaration of Helsinki,and the permission of Ethic Committee and written informed consent was obtained before entering in this trial.Thirty healthy volunteers were included with the mean age (24.80 ± 1.98) years old,equivalent refractive diopter (-1.92 ± 2.02) D and mean cylinder (-0.19±0.58) D.The presenting pattern of the targets was designed as focus gaze and relaxed gaze.The accommodative response and accommodative fluctuation in the complete corrected right eyes for the different targets at the 40 cm under the gazing state was recorded with Grand Seiko WAM 5500 automatic infrared refractor in the experiment.Results The mean accommodative response value was (1.86±0.26) D under the focus gaze and (1.27±0.39) D under the relax gaze,showing a statistically significant difference (t=-8.052,P=0.000).The mean fluctuate value was(0.17±0.06) D under the focus gaze,with a significant lowing in comparison with (0.28±0.17) D under the relax gaze (t =3.600,P =0.001).Conclusions These results demonstrate that the different presenting patterns of sighting target and watching ways of the subjects affect accommodation system.The accommodative response was relatively more accurate with a smaller microwavc moving under the focus gaze condition.

Background Even though the change in wavefront aberrations with correction modality is well documented in the literature,little is known about the underlying mechanism.Complete understanding of the causes responsible for the wavefront change in the combined lens-eye system is important since it provides basic knowledge for further improving the technique to correct refractive error by correcting lenses.Objective The aim of this study was to investigate the influence of refractive correction lens on optical property of the eye by analyzing Zernike aberrations in myopic eyes with contact lens correction.Methods This study was approved by the Ethic Committee of Wenzhou Medical College.Written informed consent was obtained from each subject before entering this study.Zernike aberrations of 52 myopic eyes of 26 subjects with the spherical equivalent-1.75 to-8.50 D were measured using a Hartmann-Shock wavefront sensor.The human eye aberrations were examined at the uncorrected condition,rigid-gas-permeable contact lens (RGP-CL) corrected condition and soft contact lens (Soft-CL) corrected condition.The differences of wavefront aberrations and Zernike coefficients were compared by repeated measurement of single factor variance analysis,and correlation of the aberration changes between uncorrected condition and RGP-CL corrected condition or Sofi-CL corrected condition,between the right eyes and left eyes in different conditions were analyzed by Pearson linear correlation.Results Mean total root-mean-square (tRMS) was (0.71 ± 0.30)μm,(0.54±0.19)μm and (0.74±0.32)μm in the uncorrected condition,RGP-CL corrected condition and Soft-CL corrected condition,with a significant difference (F =8.758,P＜0.001),and tRMS was significant declined under the RGP-CL corrected condition compared with uncorrected condition (t =2.746,P =0.008),and tRMS in RGP-CL corrected condition was significantly lower than that in Soft-CL corrected condition (t =3.428,P =0.001).The high RMS (hRMS) was (0.34±0.12) μm,(0.28 ±0.12) μm,(0.40±0.14) μm in the uncorrected condition,RGP-CL corrected condition and Soft-CL corrected condition,with a significant difference among them (F =10.681,P＜0.001).An insignificant decrease of hRMS was seen in the RGP-CL corrected condition compared with uncorrected condition (t =1.987,P=0.053),but hRMS value was significant higher in the Soft-CL corrected condition than that in the uncorrected condition (t=2.101,P=0.041) and RGP-CL corrected condition (t=4.266,P＜0.001).Compared with uncorrected condition,the axis astigmatism (C5) and spherical aberration (C12) in the RGP-CL corrected condition and spherical aberration (C12) in the Soft-CL corrected condition were significantly reduced (P＜0.05),and the absolute values of trefoil (C6),vertical coma (C7) and tetrafoil (C10) in the RGP-CL corrected condition were lower than those of the uncorrected condition,but vertical coma (C7) absolute value in the Soft-CL corrected condition was increased (P＜0.05).A significantly positive correlation was seen in the spherical aberration (C12) between the RGP-CL corrected condition and uncorrected condition (r =0.763,P＜0.001),and less significant correlation was in the secondary astigmatism (C11) between the Soft-CL corrected condition and uncorrected condition(r=0.469,P＜0.001).Conclusions Different contact lens corrected conditions exert their effects on ocular wavefront structure due to its unique interaction with the eye.RGP-CL wearing has strong modification on wavefront aberrations probably due to its molding effect on corneal surface,which reduces the bilateral symmetry.High order wavefront aberration can be modified by Soft-CL wearing.

Objective: To analyze the characteristics and influencing factors of the newly diagnosed cases locally infected with HIV through sexual contact in Jinhua,so as to provide reference for AIDS prevention and control. Methods: An epidemiological survey was conducted among the HIV/AIDS cases diagnosed in 2017 in Jinhua to collect the information about demographic characteristics,local infection and sexual behaviors. The logistic regression model was used to analyze the related factors for local HIV infection. Results: A total of 438 HIV/AIDS cases infected through sexual contact were recruited,with 272（62.10%）cases infected in Jinhua. The proportion of local infection was 86.67%,79.47%,63.04%,69.09%,77.46% and 77.97%,respectively,among those people aged 60 years or over,permanent residents in Jinhua,employees / students,farmers,those who had lived in Jinhua for more than five years,and those who had a HIV testing in one year. The Results of the multivariate logistic regression analysis showed that heterosexual transmission cases who were permanent residents in Jinhua（OR=3.437,95%CI：1.250-9.451）,who had lived in Jinhua for more than five years（OR=3.609,95%CI：1.403-9.284）,who had commercial heterosexual behaviors in Jinhua（OR=5.463,95%CI：2.529-11.803）were more likely to be infected with HIV in Jinhua;homosexual transmission cases who were permanent residents in Jinhua（OR=4.812,95%CI：1.744-13.275）and who had non-commercial,temporary homosexual behaviors in Jinhua（OR=10.641,95%CI：4.369-25.916）were more likely to be infected with HIV in Jinhua. Conclusion Among the HIV/AIDS cases diagnosed in 2017 infected through sexual contact in Jinhua,having permanent residence,long-term residence,commercial heterosexual behaviors and non-commercial,temporary homosexual behaviors were risk factors for local infection.

Objective: To investigate whether insulin stimulates the translocation of glucose transporter-4 (GLUT4) and glucose uptak e in ischemic myocardium. Methods: Plasma concentration of gluc ose, lactate, free fatty acid and insulin were determined by autoanalyser, and G LUT4 was studied by Western blotting analysis. Results: Insulin increased GLUT4 significantly in sarcolemma of ischemic myocardium ［(25±4)% vs (40±6)%］, and GLUT4 content in intracellular membrane decreased proporti onally. The glucose uptake increased significantly in insulin-ischemic myocardi um. The uptake of insulin-ischemic myocardium was almost 2 times that of ischem ic myocardium. Conclusion: Insulin stimulation results in GLUT4 translocation and increases glucose uptake in ischemic myocardium. When myocardi al ischemia occurs, insulin is helpful in increasing myocardial glucose uptake a nd utilization.

AIM To observe the changes of serum ROS,MDA,SOD levels in chronic renal failure (CRF) patients with damp-heat syndrome and to explore the intervention effect of Qingshen Granules (Hedyotis diffusae Herba,Salviae miltiorrhizae Radix et Rhizoma,Artemisiae scopariae Herba,etc.) on oxidative stress.METHODS Seventy cases of CRF patients with damp-heat syndrome were randomly and equally divided into control group and treatment group.Sixty cases completed the study,thirty-one cases in the treatment group,twenty-nine cases in the control group.Twenty other cases served as the normal group.The treatment group and the control group were given the basic treatment of western medicine and retention enema of TCM.The treatment group was added Qingshen Granules for eight weeks.The levels of U-Pro/24 h,Scr,BUN,estimated glomerular filtration rate (eGFR),serum ROS,MDA and SOD were measured before and after the treatment,and were compared with the normal group.RESULTS Both total effective rates on disease and on traditional Chinese medicine syndrome in the treatment group were 83.87％,significantly higher than those in the control group (51.72％ and 48.28％),respectively.The levels of U-Pro/24 h,Scr and BUN were obviously lower in the treatment group after the treatment,and eGFR was obviously higher as compared with those in the control group.Before the treatment,the levels of ROS and MDA in the treatment and control groups were significantly higher than those in the normal group,and the level of SOD was significantly lower;the levels of ROS and MDA were reduced in the treatment group after the treatment,and the level of SOD was increased;these changes in the treatment group were more significant than those in the control group.CONCLUSION Qingshen Granules can ameliorate clinical symptoms in CRF patients with damp-heat syndrome,decrease the levels of U-Pro/24 h,Scr and BUN,increase eGFR level,inhibit oxidative stress,and enhance antioxidant capacity,ultimately delay the development of renal fibrosis.

Objective To investigate the clinical outcome of patients receiving stereotacticcannula placement for hypertensive intracerebral hematoma drainage and the relationship between thedrainage cannula and the cerebral angioarchitecture. Methods Sixty-three patients with hypertensiveintracerebral hematoma underwent operations for stereotactic placement of a soft tube for hematomadrainage. CT angiography and CT venography were performed prior to cannula withdrawal after thepatients' condition was stabilized or complete hematoma drainage. The relationship between the drainagecarmula, cerebral angioarchitecture and the entry route of the cannula were observed. ResultsPostoperative CT angiography and CT venography showed that the entry route of the cannula allowedsafe passage of the cannula along the cerebral arteries and veins, and the position of the cannula wasaccurate in all the patients. Satisfactory hematoma drainage and good postoperative recovery wasachieved in all the patients, and no significant injuries to the adjacent cerebral arteries or veins occurredin these cases. Conclusion Stereotactic cannula placement with the minimally invasive technique forhemotoma drainage causes minimal injury and is safe, effective, cost-effective and convenient fortreatment of hypertensive intracerebral hematoma.

We investigated the prevalence of Bartonella infections in ticks, mites and small mammals (rodents, insectivores and weasels) collected during 2001 through 2004, from various military installations and training sites in Korea, using PCR and sequence analysis of 16S rRNA, 23S rRNA and groEL heat shock protein genes. The prevalence of Bartonella spp. was 5.2% (n = 1, 305 sample pools) in ticks, 19.1% (n = 21) in mesostigmatid mites and 13.7% (n = 424 individuals) in small mammals. The prevalence within the family Ixodidae was, 4.4% (n = 1, 173) in Haemaphysalis longicornis (scrub tick), 2.7% (n = 74) in H. flava, 5.0% (n = 20) in Ixodes nipponensis, 11.1% (n = 9) in I. turdus, 33.3% (n = 3) in I. persulcatus and 42.3% (n = 26) in Ixodes spp. ticks. In rodents, the prevalence rate was, 6.7% (n = 373) in Apodemus agrarius (striped field mouse) and 11.1% (n = 9) in Eothenomys regulus (Korean red-backed vole) and in an insectivore, Crocidura lasiura, 12.1% (n = 33). Neither of the two weasels were positive for Bartonella spp. Phylogenetic analysis based on amino acid sequence of a portion of the groEL gene amplified from one A. agrarius spleen was identical to B. elizabethae species. We demonstrated the presence of Bartonella DNA in H. longicornis, H. flava and I. nipponensis ticks, indicating that these ticks should be added to the growing list of potential tick vectors and warrants further detailed investigations to disclose their possible roles in Bartonella infection cycles.
