AIM: To examine how three distinct central positioning techniques for anterior capsulotomy-pupil center, limbus center, and lens apex-affect intraocular lens(IOL)placement and visual quality following femtosecond laser-assisted cataract surgery(FLACS).METHODS: A total of 36 patients(72 eyes)with age-related cataracts who underwent FLACS and ZCB00 aspherical IOL implantation at Aier Eye Hospital Medical Center, Anhui Medical University between January and December 2023 were included in this prospective study. Patients were divided into three groups based on the central positioning mode for anterior capsulotomy: pupil center, limbus center, and lens apex center groups. IOL alignment and displacement were evaluated using the Casia2 device, and the postoperative visual quality was assessed.RESULTS: At 1 d postoperatively, the IOL tilt for the pupil, limbus, and apex groups were 3.96°±1.51°, 4.63°±1.87°, and 3.90°±2.24°, respectively(F=1.07, P=0.35); IOL decentration values were 0.21±0.10 mm, 0.23±0.16 mm, and 0.21±0.12 mm, respectively(F=0.14, P=0.87); total higher-order aberrations were 0.32±0.40 μm, 0.56±0.61 μm, and 0.53±0.60 μm, respectively(F=1.38, P=0.26); and coma aberrations values were 0.13±0.10 μm, 0.16±0.15 μm, and 0.14±0.15 μm, respectively(F=0.3, P=0.74). All results obtained postoperative day 1 did not differ significantly. At 3 mo postoperatively, IOL tilt values were 5.42°±2.00°, 3.96°±1.44°, and 3.20°±1.19°, respectively(F=12.40, P<0.001); IOL decentration values were 0.33±0.07 mm, 0.23±0.11 mm, and 0.21±0.11 mm, respectively(F=4.99, P=0.008); total higher-order aberrations were 0.67±0.29 μm, 0.44±0.37 μm, and 0.42±0.19 μm, respectively(F=5.50, P=0.006); and coma aberrations values were 0.21±0.12 μm, 0.19±0.12 μm, and 0.12±0.11 μm, respectively(F=3.87, P=0.03). All results obtained 3 mo postoperatively were statistically significant.CONCLUSION: Using the lens apex as the central positioning mode for anterior capsulotomy in FLACS improves postoperative IOL stability and reduces postoperative IOL tilt and decentration. If the lens apex cannot be determined intraoperatively, the limbus center-positioning mode is recommended.

Chemotherapy-induced complications, particularly lethal cardiovascular diseases, pose significant challenges for cancer survivors. The intertwined adverse effects, brought by cancer and its complication, further complicate anticancer therapy and lead to diminished clinical outcomes. Simple supplementation of cardioprotective agents falls short in addressing these challenges. Developing bi-functional co-therapy agents provided another potential solution to consolidate the chemotherapy and reduce cardiac events simultaneously. Drug repurposing was naturally endowed with co-therapeutic potential of two indications, implying a unique chance in the development of bi-functional agents. Herein, we further proposed a novel "trilogy of drug repurposing" strategy that comprises function-based, target-focused, and scaffold-driven repurposing approaches, aiming to systematically elucidate the advantages of repurposed drugs in rationally developing bi-functional agent. Through function-based repurposing, a cardioprotective agent, carvedilol (CAR), was identified as a potential neddylation inhibitor to suppress lung cancer growth. Employing target-focused SAR studies and scaffold-driven drug design, we synthesized 44 CAR derivatives to achieve a balance between anticancer and cardioprotection. Remarkably, optimal derivative 43 displayed promising bi-functional effects, especially in various self-established heart failure mice models with and without tumor-bearing. Collectively, the present study validated the practicability of the "trilogy of drug repurposing" strategy in the development of bi-functional co-therapy agents.

In order to meet the market demand for the fast and accurate genetic detection of African swine fever virus(ASFV),a new method for EIS-qPCR detection was established with a rapid,high sensitivity,and pollution prevention.Primers and probes for a duplex qPCR were designed based on the conserved region of ASFV virus p72 gene and the endogenous internal standard(EIS)cytb gene sequence in pigs.An anti-contamination system was established with uracil DNA N-gly-cosylase enzyme in the reaction system.The results showed that the method can finish the rapid qPCR detection of ASFV within 30 min with a minimal detection limit of 4.12 copies/μL.Moreo-ver,the method only detected the ASFV p72 gene,and no amplifications of classical swine fever vi-rus(CSFV),pseudorabies virus(PRV),porcine parvo virus(PPV),porcine reproductive and re-spiratory syndrome virus(PRRSV)and porcine circovirus type 2(PCV2)were observed.Repeti-tive results showed a coefficient of variation below 2％.With strong anti-pollution capacity,the method can effectively eliminate false-positive amplification caused by low-dose aerosol pollution.Detection results of 146 clinical samples showed a 100％consistence with the results of the com-mercial ASFV detection kit.Compared with similar technologies,the EIS-qPCR established in this study was faster,sensitive,and suitable for the rapid diagnosis of ASFV infection in the early stage,which provided the tool for the monitoring and precise prevention and control of African swine fever.

This study selected the top five general hospitals in the United States of America, collected the practice information of acupuncturists through the official website, and analyzed the professional department, expertise, professional title, education background, residency, fellowship, board certification, etc. of these acupuncturists to understand the practice situation of acupuncturists in the hospitals. The results of the study showed the practice of acupuncturists in the United States of America is improving. With further localization, locally trained acupuncturists have gradually become the main body of acupuncturists; acupuncture treatment is still mainly for analgesia, but the scope of treatment continues to expand, and departments that accept acupuncturists are gradually increasing. However, the group of licensed acupuncturists is still a minority in the group of acupuncturists in the United States of America. Native American physicians still use acupuncture as an alternative option and neglect to obtain a license. The entry barrier for acupuncturists still needs to be raised.

Chronic heart failure （CHF）， the end stage of heart disease due to a variety of causes， features high disability rate and mortality， which has become a hot spot in cardiovascular field. As recorded in Treatise on Cold Damage（《伤寒论》）， Zhenwutang is composed of Radix Aconiti Lateralis Preparata， Poria Cocos， Rhizoma Atractylodis Macrocephalae， Paeoniae Radix Alba， and Rhizoma Zingiberis Recens. With the functions of warming Yang and excreting water， it is a classical prescription for the treatment of CHF in clinical settings. By searching China National Knowledge Infrastructure （CNKI）， PubMed， Wanfang Data， and VIP， we find Zhenwutang exerts therapeutic effect on CHF through multiple targets and multiple pathways. Experiments show that it alleviates CHF by antagonizing the overactivation of neuroendocrine system， inhibiting immune-inflammatory response， suppressing cardiac remodeling， restricting apoptosis， regulating autophagy， improving myocardial energy metabolism， inhibiting oxidative stress injury， protecting endothelial function， and decreasing volume load. Clinical research shows that Zhenwutang can significantly alleviate the clinical symptoms of CHF patients in a safe manner with little adverse reactions. This paper systematically summarizes the mechanisms of and clinical research on Zhenwutang in the treatment of CHF in recent years， so as to provide theoretical and experimental data for the further research and development of Zhenwutang.

Objective     To analyze the clinical information of COVID-19 patients of Shanghai National Exhibition and Convention Center cabin hospital, and to explore the medical management strategy to provide thoughtful suggestions for other cabin hospitals and governments as valuable references. Methods     The clinical data of 174 308 patients confirmed COVID-19 in Shanghai National Exhibition and Convention Center cabin hospital from April 9 to May 31, 2022 were retrospectively reviewed. There were 103 539 male and 70 769 female patients, with an average age of 41.50±15.30 years. Medical and nursing management strategy was summarized. Results     Among the 174 308 patients, 71.5% (124 630 patients) were asymptomatic. The vaccination rate of patients with COVID-19 in the cabin hospital was 76.5% (133 338 patients), and the majority of none vaccinated patients were children under the age of 10 years and the elderly over the age of 60 years, the vaccination rate of whom was only 25.0% (1 322 patients) and 63.9% (13 715 patients), respectively. In addition, the proportion of mild symptom type in the patients not vaccinated was significantly higher than that in the vaccinated patients (P≤0.01). The average hospitalization time of patients in cabin hospital was 7.39±0.53 days, which was 7.01±2.12 days for patients under 60 years and 8.21±0.82 days for patients over 60 years. The hospitalization time of elderly patients was significantly longer (P≤0.01), and the hospitalization time of elderly patients at age over 60 years without vaccination was 8.94±1.71 days, which was significantly longer than the average hospitalization time and the time of elderly patients vaccinated (P≤0.01). The number of patients combined with basic diseases was 27 864 (16.0%), of which cardiovascular diseases accounted for 81.3% (22 653 patients). A total of 2 085 patients were transferred and treated in designated hospitals. Conclusion     Large scale cabin hospitals are helpful to cut off the source of infection. Attention shall be paid to the sorting of admission and timely transfer to other hospital during the patients management. Most of the patients have a good prognosis after treatment. The vaccination of key population and community-based screening will be the next step of focus.

Objective: To establish the knowledge graph of “disease-syndrome-symptom-method-formula” in Treatise on Febrile Diseases (Shang Han Lun,《伤寒论》) for reducing the fuzziness and uncertainty of data, and for laying a foundation for later knowledge reasoning and its application. Methods: Under the guidance of experts in the classical formula of traditional Chinese medicine (TCM), the method of “top-down as the main, bottom-up as the auxiliary” was adopted to carry out knowledge extraction, knowledge fusion, and knowledge storage from the five aspects of the disease, syndrome, symptom, method, and formula for the original text of Treatise on Febrile Diseases, and so the knowledge graph of Treatise on Febrile Diseases was constructed. On this basis, the knowledge structure query and the knowledge relevance query were realized in a visual manner. Results: The knowledge graph of “disease-syndrome-symptom-method-formula” in the Treatise on Febrile Diseases was constructed, containing 6 469 entities and 10 911 relational triples, on which the query of entities and their relationships can be carried out and the query result can be visualized. Conclusion The knowledge graph of Treatise on Febrile Diseases systematically realizes its digitization of the knowledge system, and improves the completeness and accuracy of the knowledge representation, and the connection between “disease-syndrome-symptom-treatment-formula”, which is conducive to the sharing and reuse of knowledge can be obtained in a clear and efficient way.
