		                        			Objective:To construct an artificial intelligence (AI)-assisted system based on deep learning for corneal in vivo confocal microscopy (IVCM) image recognition and to evaluate its value in clinical applications. Methods:A diagnostic study was conducted.A total of 18 860 corneal images were collected from 331 subjects who underwent IVCM examination at Renmin Hospital of Wuhan University and Zhongnan Hospital of Wuhan University from May 2021 to September 2022.The collected images were used for model training and testing after being reviewed and classified by corneal experts.The model design included a low-quality image filtering model, a corneal image diagnosis model, and a 4-layer identification model for corneal epithelium, Bowman membrane, stroma, and endothelium, to initially determine normal and abnormal corneal images and corresponding corneal layers.A human-machine competition was conducted with another 360 database-independent IVCM images to compare the accuracy and time spent on image recognition by three senior ophthalmologists and the AI system.In addition, 8 trainees without IVCM training and with less than three years of clinical experience were selected to recognize the same 360 images without and with model assistance to analyze the effectiveness of model assistance.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2021-K148).Results:The accuracy of this diagnostic model in screening high-quality images was 0.954.Its overall accuracy in identifying normal/abnormal corneal images was 0.916 and 0.896 in the internal and external test sets, respectively.Its accuracy reached 0.983, 0.925 in the internal test sets and 0.988, 0.929 in the external test sets in identifying corneal layers of normal and abnormal images, respectively.In the human-machine competition, the overall recognition accuracy of the model was 0.878, which was similar to the average accuracy of the three senior physicians and was approximately 300 times faster than the experts in recognition speed.Trainees assisted by the system achieved an accuracy of 0.816±0.043 in identifying corneal layers of normal and abnormal images, which was significantly higher than 0.669±0.061 without model assistance ( t=6.304, P<0.001). Conclusions:A deep learning-based assistant system for corneal IVCM image recognition is successfully constructed.This system can discriminate normal/abnormal corneal images and diagnose the corresponding corneal layer of the images, which can improve the efficiency of clinical diagnosis and assist doctors in training and learning.

		                        			 Objective To investigate the prevalence of parasitic infections in market-sold aquatic products in Shanghai Municipality, and to understand the knowledge and practice towards food-borne parasitic diseases among residents, so as to provide insights into the surveillance and control of food-borne parasitic diseases. Methods Freshwater products, seawater products and pickled products were randomly obtained from agricultural trade markets, supermarkets, retail stores and restaurants in Huangpu, Putuo, Minhang and Qingpu districts of Shanghai Municipality from 2020 to 2023. Parasite metacercariae and larvae were detected in these aquatic products using pressing method, digestion method and the dissection method, and the detection of parasitic infection was compared in different types of aquatic products. In addition, the knowledge and practice towards food-borne parasitic diseases were investigated among residents aged 10-80 years old who randomly selected from agricultural trade markets, supermarkets, community streets and other population concentration areas in these four districts by questionnaire in 2023, and the awareness of food-borne parasitic diseases knowledge and percentage of healthy behaviors formation were analyzed. Results A total of 2 109 aquatic products sampled from Huangpu, Putuo, Minhang and Qingpu districts of Shanghai Municipality from 2020 to 2023 were detected, and there were 317 products detected with parasitic infections, with an overall detection rate of 15.03%. There were 8 products detected with parasitic infections in 1 221 freshwater products, with a detection rate of 0.66%, and Clonorchis sinensis was the predominant parasite, which was detected in Pseudorasbora parva, Rhodeus amarus and Carassius auratus. There were 82 products detected with parasitic infections in 501 seawater products, with a detection rate of 16.37%, and Anisakis was the predominant parasite, which was detected in Trichiurus lepturus, Larimichthys polyactis, Pneumatophorus japonicus, Collchthys lucidus, Mugil cephalus, Larimichthys crocea, Scomberomorus niphonius, Stromateoides argenteus and Cololabis saira. There were 227 products detected with parasitic infections in 387 pickled products, with a detection rate of 58.66%, and the prevalence rates of Echinostoma metacercariae were 76.27% (225/295) in Bullacta exarata and 11.11% (2/18) in crab pastes, respectively (χ2 = 159.511, P < 0.05). No Paragonimus infection was found in freshwater shrimps, crabs and pickled products, and no Diphyllobothrium latum larvae infection was detected in freshwater and seawater fish. Questionnaire surveys showed that the awareness of food-borne parasitic diseases knowledge was 79.00% (222/281), and the percentages of washing hands before and after meals, not drinking filtered water or tap water directly, not eating raw or semi-raw food, being willing to change special dietary preferences or bad living habits for health, and being willing to learn more about food-borne parasitic diseases knowledge were 99.64% (280/281), 72.24% (203/281), 56.23% (158/281), 96.80% (272/281) and 97.51% (274/281) among residents living in Huangpu, Putuo, Minhang and Qingpu districts, respectively. Conclusions There are food-borne parasite contaminations in market-sold aquatic products in Shanghai Municipality. Although residents are aware of food-borne parasitic diseases knowledge, sustainable surveillance of food-borne parasitic diseases and improved health education are required to minimize the risk of human parasitic infections.

		                        			Lung cancer is the cancer type with the highest incidence rate and mortality among malignant tumors in China.Tumor associated macrophages(TAMs)are closely related to the occurrence,development,invasion and metastasis,and treatment tolerance of lung cancer.This article explored the etiology and pathogenesis of lung cancer in TCM,as well as the key role of TAMs in lung cancer.It was found that the local imbalance of yin and yang in TAMs,as well as the overall imbalance of yin and yang in the tumor microenvironment and whole body,were important reasons for the formation and progression of lung cancer.In the progression and sequelae of lung cancer,M1 and M2 type TAMs each plays different roles and has different yin and yang properties.Both of them maintain a constantly developing and changing state of mutual use,opposing constraints,and balance of growth and decline.Based on the yin-yang theory in TCM,according to the progression of lung cancer and the imbalance of yin and yang,rational selection and medication can adjust the phenotype of TAMs,promote the overall balance of yin and yang,and provide reference for the clinical prevention and treatment of lung cancer.

		                        			OBJECTIVE To evaluate the clinical effectiveness and safety of domestic generic and imported original clopidogrel for antiplatelet therapy in patients with acute coronary syndrome (ACS). METHODS The clinical data of ACS patients in Nanjing Drum Tower Hospital of China Pharmaceutical University from January 2020 to June 2021 were retrospectively collected by using electronic medical record system, and the patients were divided into original drug group (321 cases) and generic drug group (328 cases) according to the drug use. Both groups were given dual antiplatelet therapy with clopidogrel and aspirin. The effectiveness and safety outcomes of the two groups were followed up for 12 months and compared, the related influential factors were analyzed. RESULTS Major adverse cardiovascular events (MACE) occurred in 16 and 22 patients in original drug group and generic drug group respectively, including nonfatal myocardial infarction (4 and 5 cases), stroke (2 and 4 cases), revascularization (8 and 3 cases), cardiovascular related death (2 and 4 cases), and all-cause death (4 and 6 cases). There were 12 and 7 patients with major bleeding events, 38 and 29 patients with minor bleeding events, and 33 and 21 patients with non-bleeding adverse events. There was no statistically significant difference in the cumulative incidence of related events (P values of Log-Rank tests were all greater than 0.05). Cox regression analysis showed that the use of generic clopidogrel did not increase the risk of MACE and major bleeding events in ACS patients [hazard ratio of 1.305 and 0.416, 95% confidence interval of (0.678, 2.512) and (0.155, 1.117), respectively, P>0.05], and the combination of proton pump inhibitors (PPI) could reduce the risk of major bleeding events [hazard ratio of 0.196, 95% confidence interval of (0.063, 0.611), P<0.05]. CONCLUSIONS Compared with imported original drug, domestic generic clopidogrel has similar clinical effectiveness and good safety. Combined use of PPI may be a beneficial factor to reduce the occurrence of major bleeding events in patients.
