Objective:To evaluate the value of applying an artificial intelligence (AI) system for diabetic retinopathy (DR) detection and referral in community.Methods:A diagnostic test study was conducted.Four hundred and twenty-one patients (812 eyes) diagnosed with diabetes in three Dongguan community healthcare centers from January 1, 2020 to December 31, 2021 were enrolled.There were 267 males, accounting for 63.42% and 154 females, accounting for 36.58%.The subjects were 18-82 years old, with an average age of (51.72±11.28) years.The disease course of the subjects was 0-30 years, with an average course of 3.00 (1.00, 7.00) years.At least one macula-centered 50-degree fundus image was taken for each eye to build a DR image database.All the images were independently analyzed by an AI-assisted diagnostic system for DR, trained and qualified community physicians and ophthalmologists to make diagnosis including with or without DR, referable diabetic retinopathy (RDR) and referral recommendation or not.With diagnoses from ophthalmologists as the standard, sensitivity and specificity of the AI system in detecting DR and RDR were evaluated.The consistency and effective referral rate of the AI system and community physicians in detecting DR, especially in detecting RDR were evaluzted.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Dongguan Tungwah Hospital (No.2019DHLL046).Results:Of 812 eyes, 242 eyes were diagnosed with DR, including 23 with mild nonproliferative diabetic retinopathy (NPDR), 120 with moderate NPDR, 60 with severe NPDR and 39 with proliferative diabetic retinopathy (PDR). The other 570 eyes were diagnosed without DR.The sensitivity/specificity of AI system to detect DR and RDR was 87.60%/97.89% and 90.41%/96.29%, respectively.Compared with the ophthalmologists' diagnosis, the Cohen' s Kappa statistic of AI system to detect DR/RDR was 0.87/0.87, which was lower than 0.93/0.98 of community physicians.Among the referral-recommended cases by ophthalmologists, the effective referral rate of the AI system was 90.87% (199/219), which was higher than 89.50% (196/219) of community physicians, without statistically significant difference ( P=1.000). Conclusions:The AI system shows high sensitivity, specificity and consistency in DR detection, especially in RDR.The AI system is better in recognizing RDR than trained community physicians.

Objective:To compare the clinical efficacy of hyperbaric oxygen combined with herbal cake-separated moxibustion on umbilicus and retention enema in treating acute radiation proctitis（ARP），and to statistically analyze their rates of acceptance and satisfaction.Methods:A total of 64 patients with ARP after radiotherapy for cervical cancer treated in Linyi Central Hospital from June 2016 to December 2021 were selected and divided into observation group（ n=32）and control group（ n=32）according to the number table method. The control group was treated with（Smecta and Kangfuxin solution）retention enema combined with hyperbaric oxygen，and the observation group was treated with herbal cake-separated moxibustion on umbilicus combined with hyperbaric oxygen. The degree of rectal injury before and after radiotherapy was evaluated according to the criteria of the Radiation Therapy Oncology Group（RTOG），and the clinical efficacy was analyzed. The symptom score and total score of ARP patients were calculated by international scoring standards for long-term complication of radiotherapy，and the satisfaction rate and acceptance rate of the two groups were analyzed. Results:After four courses of treatment，compared with the same group before treatment，the classifications of clinical symptoms in both the observation group and the control group were significantly improved（ P < 0.01），but there was no significant difference between the observation group and the control group（ P > 0.05）. The acceptance rate and satisfaction rate of patients treated with herbal cake-separated moxibustion on umbilicus in the observation group was significantly higher than that in the control group（ P < 0.01）. Conclusion:Both hyperbaric oxygen combined with herbal cake-separated moxibustion on umbilicus and retention enema in treating ARP can achieve good clinical therapeutic effect. As a non-invasive approach，the herbal cake-separated moxibustion on umbilicus can avoid aggravating rectal mucosa and perianal injury caused by repeated drug enema. Meanwhile，the herbal cake-separated moxibustion on umbilicus is simple and easy to operate，with less pain for patients，high rates of acceptability and satisfaction，which can be popularized and applied.

Objective: To evaluate the relationship between the offset of a laser-assisted flap using the WaveLight FS200 femtosecond laser and the clinical results after femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). Methods: In this prospective cohort study, 125 patients who underwent FS-LASIK for myopia by WaveLight FS200 femtosecond laser from June 2017 to July 2018 at the Tungwah Ophthalmic Center were divided into two groups according to the offset of the corneal flap from the pupil center: the no-offset group (57 eyes) and the certain-offset group (68 eyes); the baseline data, including age, sex, uncorrected visual acuity(UCVA), spherical degree, and central corneal thickness were matched in the two groups.UCVA, residual astigmatism, spherical degree, corneal curvature and aberration were observed 1 week and 1 month after surgery.The study protocol was approved by the Ethics Committee of Tungwah Hospital of Sun Yat-Sen University (No.2017DHLL004). Written informed consent was obtained from each subject prior to entering the study cohort. Results: UCVA, corneal curvature, spherical degree, spherical and corneal aberration between the two groups were not significantly different (all at P>0.05). One week after surgery, the residual astigmatism was ≤-0.50 D in 50 eyes (87.7%, 50/57)and >-0.50 D in 7 eyes (12.3%, 7/57) in the no-offset group; the residual astigmatism was ≤-0.50 D in 50 eyes (73.5%, 50/68) and >-0.50 D in 18 eyes (26.5%, 18/68) in the no-offset group.The residual astigmatism between the two groups 1 week after surgery was significantly different (χ²=3.902, P=0.048), and there was no significant difference in residual astigmatism 1 month after surgery (χ²=2.031, P=0.068). The trefoil of the no-offset group was statistically less than of the certain-offset group at 1 week and 1 month after surgery (0.05[0.04, 0.08]vs.0.06[0.04, 0.10]; 0.05[0.03, 0.07]vs.0.06[0.05, 0.09])(Z=-2.245, P=0.022; Z=-2.370, P=0.018). The spherical aberration and coma were not significantly different between the two groups at 1 week and 1 month after surgery (both at P>0.05). Conclusions The offset from femtosecond laser-assisted flap by WaveLight FS200 has no effect on long-term visual acuity or residual astigmatism.Some patients may have different visual experiences because of the residual astigmatism and higher order aberration during the early postoperative stage.

Objective Dilated cardiomyopathy (DCM) is generally considered to be accompanied by both left and right ventricular dysfunction,but most studies only analyze the left ventricular function. In this study, we evaluated the effect of arotinolol on right ventricular function in patients with DCM. Methods Right ventricular ejection fraction (RVEF) and right ventricular diameter (RVD) were measured by two-dimensional echocardiography (2-DE) in 33 DCM patients; RVEF measured by first-pass radionuclide angiography (FPRA) was compared with that by 2-DE. Results The treatment with arotinolol for one year resulted in a reduction in the right ventricular diameter (baseline, 23.0 ± 8.3 mm vs after one-year treatment, 20.7 ± 5.4 mm; P=0.004 ) and an associated increase in ejection fraction (baseline, 36.9 ± 10.3% vs after one-year treatment, 45.8 ± 9.6%; P ＜ 0.001 ); there is a high correlation between the 2-DE method and radionuclide ventriculographic method. The correlation coefficient is 0.933 (P＜0.001). Conclusion Arotinolol therapy could not only improve left ventricular function, but also improve right ventricular function in DCM patients.
