RESUMO
Eyelid tumor is a serious eye disease that leads to vision loss or even blindness.The similarity between benign and malignant characteristics makes it difficult for ophthalmologists lacking clinical experience to distinguish between them.To address the problem,a method(ResNet101_CBAM)based on two-stage target localization using fully convolutional one-stage object detection(FCOS)and residual network incorporating a dual attention mechanism is proposed to realize the automatic diagnosis of benign and malignant eyelid tumors.FCOS is used to automatically localize the overall contour of the orbit,removing the background and surrounding noise,and then finely localize the tumor lesion inside the orbit.The obtained lesion region is input into ResNet101_CBAM for the automatic diagnosis of benign and malignant eyelid tumors.The experimental results show that the average precision of the target localization algorithm for tumor lesion is 0.821,and that compared with ResNet101,ResNet101_CBAM improves the sensitivity and accuracy in eyelid tumor classification by 4.7%and 3.0%,respectively,indicating that the proposed model has superior performances in the automatic diagnosis of benign and malignant eyelid tumors.

Objective To observe the effect ofJiuwei-Sanjie capsuls combined with levothyroxine sodium on IL-17 and IL-23 expression in the patients with Hashimoto’s thyroiditis (HT). Methods A total of 76 HT patients were randomly divided into the control group (n=38) and observation group (n=38). The control group was treated with Levothyroxine Sodium, and the observation group was treated with Levothyroxine Sodium andJiuwei-Sanjie capsuls. The expression of FT3, FT4, TSH, TGAb, and TPOAb were detected by chemiluminescent immunoassay. The expression of IL-17 and IL-23 were detected by ELISA analysis. The clinical effect were compared.ResultsThe clinical effect was 94.7% (36/38) in observation group, which was better than that of 81.6% (31/38) in control group (χ2=2.316,P=0.042) . After treatment, the expression of IL-17 (22.32 ± 4.25 ng/mlvs. 31.55 ± 6.84 ng/ml,t=2.416) and IL-23 (14.72 ± 3.42 ng/mlvs. 23.27 ± 5.26 ng/ml, t=2.512) in observation group was lower than that in control group (P expression in patients with Hashimoto's thyroiditis, and improve thyroid function.
RESUMO
Background Refractive regression is a common complication of high myopia after laser in situ keratomileusis (LASIK),and it affects the stability of surgery.Objective This study was to observe the preventive effect of timolol on refractive regression in high myopia after LASIK.Methods A perspective randomized controlled trial was performed under the approval of Affiliated Hospital of Zunyi Medical College and the informed consent of the patients.Sixty eyes of 60 patients with high myopia (-7.16±0.95) D for LASIK were randomized into experimental group and control group.Regular eye drops were topically administered in the patients after LASIK in both groups,and timolol 0.5 % was added topically from 1 day after LASIK.The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),spherical equivalent (SE),corneal anterior surface curvature,intraocular pressure (IOP),central corneal thickness (CCT) were measured before LASIK,1 week,1 month,3 months and 6 months after LASIK,respectively.Residual stromal bed thickness was calculated before LASIK.The differences of above-mentioned indexes were analyzed and compared between the two groups and among the various time points using repetitive measurements analysis of variance,independent simple t test and Bonferroni test.Results No significant differences were found in the demography between the experimental group and the control group,including age,UCVA,BCVA,SE,IOP,corneal anterior surface curvature,CCT and residual stromal bed thickness (all at P>0.05).UCVA was significantly different between the two groups among various time points (Fgroup =3.91,P<0.05 ; Ftime =3.80,P<0.05),and the UCVA was significantly higher in the experimental group than the control group 6 months after LASIK (t=2.97,P<0.05),and UCVA was gradually increased as the lapse of postoperative time with the significant difference between 7 days and 6 months after LASIK in the experimental group (P<0.05).No significant difference was seen in the BCVA between the two groups at various postoperative time points (Fgroup =2.44,P>0.05;Ftime =2.31,P>0.05).SE refraction in both groups were significantly reduced from 7 days through 6 months after LASIK,showing significant difference between the groups at various time points after LASIK(Fgroup =11.52,P<0.05;Ftime =22.06,P<0.05).The SE refraction was higher in the experimental group than that in the control group 6 months after LASIK (t =2.47,P<0.05).Corrected IOP in the experimental group was lower than that of the control group at 7 days,1 month and 3 months after LASIK,respectively (Fgroup =14.83,P<0.05).The change of CCT was not statistically different between the control group and the experimental group (Fgroup =0.04,P>0.05).The anterior corneal surface curvature was steady in the experimental group during the following-up duration after LASIK,while the control group was growing gradually (Ftime =18.73,P<0.05).Conclusions The study data show that topical administration of 0.5% timolol early in high myopia following LASIK is effective for the reduction of the refractive regression.It is suggested that 0.5% timolol can prevent cornea ectasia by lowering IOP.Reduction of the IOP may contribute to improving the regression after keratorefractive surgery in high myopic eyes.

There was a significant reduction of blood glucose in two groups at the end of treatment(both P<0.01), but C-peptide level was markedly increased(P<0.05) only in glipizide-treatedpatients.Conclusion The changes of IGF-1 is markedly different between metformin-treated and glipizide-treated patients with type Ⅱ diabetes mellitus.
RESUMO
Objective:To further discussion the results of the free transplantation of dorsal flap of the foot repair hand trauma.Methods:From Feb,1990 to Nov,1995,single or combined and com- plex dorsal flaps of the foot were used to repair 32 trauma of hand.a.Results:The follow-up visit was 1 year to 5 years,all flaps survived.Skin graft on donor sites grew healing.The wounded hand can move well and has a good recovery of sensation and looks.There is not influence on the function of the foot.Conclusions:The limit of repairing hand trauma in a large area can be solved by using combined dorsal flaps of the foot.The problem that skin graft on donor sites can't grow union ideally can be solved as long as aponeurosis and periosteum are kept completely and binding up the wound with double pressure.Dorsal flap of the foot is the ideal flap nowadays to repair hand trauma.
RESUMO
Aim To investigate whether capacitative Ca~(2+) entry involved in excitation-contraction coupling in rat distal colon smooth muscle.Methods Changes of isolated organ's tension were monitored with force-displacement transducer and Powerlab 4/25T recording system.Results Thapsigargin(10 nmol?L~(-1)~1 ?mol?L~(-1))produced slowly developing sustained contractions in isolated distal colon smooth muscle strips of rats.The timed contractile responses to thapsigargin(10 n mol?L~(1)-1 ?mol?L~(-1)) were significantly different.The contractile response to Ca~(2+) reintroduction following incubation of strips in a Ca~(2+)-free Krebs in the presense of thapsigargin was significantly higher than in its absence(99%?28% vs 70%?8%).Contractile responses to Ca~(2+)reintroduction following depletion of sarcoplasmic reticulum Ca~(2+) stores with thapsigargin were attenuated by La~(3+),while unaffected by verapamil.Conclusion Contractile responses to Ca~(2+)reintroduction following depletion of sarcoplasmic reticulum Ca~(2+)stores with thapsigargin,are mediated by capacitative Ca~(2+)entry.The results suggested that CCE provided activator Ca~(2+)for the contraction and participated in excitation-contraction process in rat distal colon smooth muscle.
