AIM: To investigate the abnormal conditions and change patterns of accommodative facility in patients with different refractive states before and after small incision lenticule extraction(SMILE)surgery.METHODS:A prospective clinical cohort study was conducted. A total of 59 patients(118 eyes)who underwent SMILE surgery and had visual function files established in our hospital from June to December 2023 were randomly selected, including 37 males and 22 females, aged 18-35 years(with an average age of 25.19±5.65 years). According to the preoperative spherical equivalent(SE), they were divided into two groups: the low-to-moderate myopia group(SE≥-6.00 DS)with 40 patients(80 eyes), and the high myopia group(SE<-6.00 DS)with 19 patients(38 eyes). The monocular and binocular accommodative facility before surgery and at 1 wk and 1 mo after surgery were compared, and the changes in accommodative facility before and after SMILE surgery in the two groups of patients were analyzed.RESULTS:All surgeries were completed successfully. In the low-to-moderate myopia group, 33 cases(66 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 17.5%(7/40). In the high myopia group, 15 patients(30 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 21.1%(4/19). After SMILE surgery, the uncorrected visual acuity and SE of both low-to-moderate myopia and high myopia were significantly improved(all P<0.05). The accommodative facility of the right eyes in all the patients at 1 mo after surgery was better than that before surgery and at 1 wk after surgery(P=0.002, 0.006), the accommodative facility of the left eyes was significantly increased at 1 mo after surgery than that at 1 wk after surgery(P=0.005), and the binocular accommodative facility at 1 mo after surgery was significantly increased compared with that before surgery(P<0.017). Furthermore, there were statistical significance in accommodative facility of the right eyes in the low-to-moderate group at 1 mo compared with that before surgery and at 1 wk after surgery(P=0.011, 0.004); it was significantly increased in the left eyes at 1 mo after surgery compared with that at 1 wk after surgery(P=0.001), and binocular accommodative facility at 1 mo after surgery was significantly better than that before surgery(P<0.001). Furthermore, there was no statistical significance in the right, left and binocular accommodative facility of patients in the high myopia group(all P>0.017).CONCLUSION: After SMILE surgery, the monocular accommodative facility shows a transient decrease and then exceeds the preoperative level at 1 mo after surgery, and the binocular accommodative facility gradually improves after surgery. SMILE surgery has a positive impact on the monocular and binocular accommodative facility in patients with low-to-moderate myopia, but has no significant impact on the accommodative facility in patients with high myopia. It is of clinical significance to strengthen the detection of monocular and binocular accommodative facility before and after SMILE surgery.

AIM: To analyze the changes in binocular visual function before and after small incision lenticule extraction(SMILE)in patients with different degrees of myopia.METHODS:A prospective non-randomized controlled study was conducted. A total of 94 patients(188 eyes)who visited the refractive outpatient department of the ophthalmology department of the General Hospital of the PLA from June 2022 to June 2023 and voluntarily chose SMILE were consecutively included. They were grouped according to the degree of myopia, including 24 cases(48 eyes)in the low myopia group(-3.00 D

Xenotransplantation is one of the effective ways to overcome the shortage of donor organs. However, the molecular incompatibility between xenotransplantation donors and recipients can cause rejection, which greatly limits the clinical application of xenotransplantation. In recent years, researchers have deeply explored the mechanism of xenotransplantation rejection through xenotransplantation models of pig-to-monkey and pig-to-brain death recipients, and found that the innate immune system plays an important role in rejection. Macrophages, as phagocytes in the innate immune system, not only damage xenografts through phagocytosis but also interact with other immune cells to influence the immune microenvironment of xenotransplantation. However, due to the heterogeneity of macrophages, their phenotypes and functions in xenotransplantation rejection remain unclear. Therefore, it is necessary to further explore the role of macrophages in xenotransplantation rejection. This article reviews the latest research progress of macrophages in xenotransplantation rejection, aiming to explore the mechanisms of macrophages in xenotransplantation rejection and provide references for future research.

Organ transplantation faces the challenge of a shortage of donors. Although xenotransplantation holds great potential, it is limited by rejection. Extracellular histones, as key members of damage-associated molecular patterns, have been proven in recent years to play a crucial role in transplant rejection by activating innate immunity, regulating the coagulation-inflammation network, and modulating adaptive immune responses. However, the specific functions and key mechanisms remain to be clarified. Therefore, this article reviews the structural characteristics of histones, their release pathways, the biological functions of extracellular histones, and their potential roles in xenotransplantation. It summarizes the latest research progress of extracellular histones in xenotransplantation, analyzes the shortcomings of existing research and the direction for future research, with the expectation of providing references for the application of extracellular histones in xenogeneic kidney transplantation.

Based on his extensive clinical experience and the team's mechanistic research, Professor XU Nenggui has proposed the academic concept that "the governor vessel governs the brain and treats cerebral viscus diseases", and established a novel acupuncture approach for encephalopathy treatment centered on the integrated theory of "governor vessel-brain-mind", and developed a staged acupuncture protocol of "governor vessel regulating spirit" for ischemic stroke. This article introduces the academic features of this method in treating post-stroke dysphagia from four aspects: theoretical framework, treatment principles and point selection, mechanistic research, and clinical case studies. In clinical application, the method emphasizes syndrome differentiation based on meridians, harmonization between the conception and governor vessels; precise acupoint selection to treat both form and spirit; stage-specific differentiation with targeted needling. Furthermore, Professor XU integrates basic research with clinical practice, focusing on the neurobiological mechanisms underlying the efficacy of acupuncture in treating post-stroke dysphagia.

Objective To investigate changes in serum complement C1 tumor necrosis factor-related pro-tein family 12(CTRP12)level before and after percutaneous coronary intervention(PCI)in patients with acute myocardial infarction(AMI)and the relationship of CTRP12 level with in-stent restenosis(ISR).Methods A total of 104 patients who had been diagnosed with AMI and had undergone PCI at Danyang People's Hospital in Jiangsu Province from January 2021 to June 2023 were selected.The incidence of ISR within 12 months after PCI was counted,and they were divided into an ISR group and a non-ISR group according to the results of reviewed coronary angiography.Serum CTRP12 levels were compared between the two groups before PCI and on one day before discharge.Logistic regression was used to analyze the influencing factors of ISR in AMI patients after PCI.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of CTRP12 for ISR in AMI patients after PCI.Results The incidence of ISR in 104 AMI patients at 12 months after PCI was 14.4%(15/104).As compared with the non-ISR group,the ISR group had significant increases in preoperative TIMI flow of≤1,white blood cell count,neutrophil count,TC,and LDL-C,and a significant decline in serum CTRP12 level on one day before discharge(P<0.05).In the non-ISR group,serum CTRP12 level was significantly higher on one day before discharge than its baseline(P<0.05).In the ISR group,serum CTRP12 level on one day before discharge was lower than its baseline,but the difference was not statistically significant(P>0.05).Logistic regression analysis showed that a lower CTRP12 level on one day before discharge was an independent risk factor for ISR in AMI patients after PCI(P<0.05).ROC curve analysis showed that the optimal cut-off point of serum CTRP12 on one day before discharge for predicting ISR in AMI patients after PCI was 3.89 ng/mL(sensitivity 93.3%and speci-ficity 73.0%),and the area under the ROC curve(AUC)was 0.849.Conclusions Serum CTRP12 level inone day before discharge has certain predictive value for ISR in AMI patients after PCI.CTRP12 may be a therapeutic target for ISR in AMI patients after PCI.

Objective To investigate the vaccination status and vaccination willingness of novel coronavirus in HIV/AIDS population in Yunnan.Methods From October 2021 to June 2022,a questionnaire survey was conducted among 2180 HIV/AIDS patients in Kunming,Qujing,Yuxi,Zhaotong,Puer,Baoshan,Lincang,Honghe,Wenshan,Xishuangbanna,Dali,Dehong and Nujiang prefectures.The questionnaire included age,sex,education,nationality,education level,vaccination,adverse reactions within 7 days after the vaccination,safety of COVID-19 vaccine,awareness of effectiveness,vaccination willingness and so on.Results Among the subjects,2109 completed 3 injections,accounting for 96.74%,and 71 were not vaccinated,accounting for 3.26% .Within 7 days of inoculation,local adverse reactions occurred in 116 cases,accounting for 5.50%,and systemic adverse reactions occurred in 56 cases,accounting for 2.66% .Injection site pain,fatigue and muscle pain accounted for the highest proportion of adverse symptoms in different sex,age and the Han nationality,while the proportion of minority adverse reactions was very low,and there was no difference among the different sex and age(P>0.05).The main reasons for the reluctance of HIV/AIDS population to be vaccinated were(recommended by doctors)that HIV/AIDS patients could not be vaccinated(67.61%)and may have serious adverse reactions after the vaccination(19.72%).The factors affecting the vaccination were found by logistic regression analysis,whether they were worried about infecting novel coronavirus(OR = 0.121,95% CI = 0.083～0.640,P<0.001)and how much they knew about COVID-19 vaccine(OR = 28.932,95% CI = 15.469～54.115,P<0.001),safety of vaccination(OR = 13.953,95% CI = 4.819～40.404,P<0.001)and belief in the preventive effect of vaccine(OR = 14.017,95% CI = 4.752～41.348,P<0.001)were significant factors affecting vaccination.Among the 13 prefectures and cities,Dehong(20),Zhaotong(21)and Lincang(14)had the largest number of unvaccinated people.Conclusion After the mass vaccination,the rate of adverse reaction in HIV/AIDS population is low,the symptoms are mild,the correct and scientific advice and guidance from doctors and the full understanding of the harmfulness of the disease,the safety,prevention and effectiveness of the vaccine are the key to complete vaccination and put an end to vaccine hesitancy.

Objective To investigate the changes of C1q tumor necrosis factor-related protein-12(CTRP12)levels in serum of the pa-tients with acute myocardial infarction(AMI)before and after percutaneous coronary intervention(PCI),and explore its clinical sig-nificance.Methods A total of 50 patients with AMI who underwent emergency PCI and 35 patients with normal coronary angiography results in Danyang People's Hospital from November 2021 to October 2022 were enrolled.The CTRP12 levels in peripheral venous ser-um were compared between the two groups.The levels of serum CTRP12 levels were measured before,during and on the 3rd,5th and 7th day after PCI.The serum CTRP12 levels in culprit coronary ostium and peripheral vein were compared.CTRP12 levels in peripher-al venous serum were compared at different time points after PCI.The severity of coronary artery disease was evaluated by SYNTAX score system,and the AMI patients were divided into two groups:SYNTAX score ≤22 and SYNTAX score＞22.The serum CTRP12 levels were compared between the two groups and before and after PCI.The correlation between CTRP12 and age,body mass index(BMI),fasting blood glucose,blood lipid and other factors was analyzed.The influencing factors of the severity of coronary artery le-sions were analyzed by logistic regression.Results The serum CTRP12 level in the patients with AMI was significantly lower than that in healthy controls(P＜0.05).There was no significant difference between the serum CTRP12 levels between preoperative peripheral vein and intraoperative culprit coronary orifice(P＞0.05).Compared with that before PCI,the serum CTRP12 level was lower on the 3rd day after PCI(P＜0.05),and increased on the 5th and 7th days after PCI,but no statistically significant difference was found(P＞0.05).Compared with those on the 3rd day after PCI,the serum CTRP12 levels were increased on the 5th and 7th day after PCI,but no statistically significant differences were found(all P＞0.05).Compared with that in the SYNTAX≤22 group,the CTRP12 levels were significantly lower than those before PCI and on the 3rd day after PCI(all P＜0.05),while there was no significant difference on the 5th and 7th day after PCI in SYNTAX＞22 group(all P＞0.05).CTRP12 was negatively correlated with the level of total cholesterol(TC)and positively correlated with high-density lipoprotein cholesterol(HDL-C).Univariate logistic regression analysis showed that CTRP12 was an independent influencing factor for the severity of coronary artery disease in the patients with AMI(β=-1.671,OR=0.188,P＜0.05).After adjusting for the effects of age,gender,BMI,smoking,hypertension,diabetes,fasting blood glucose,total cholesterol(TC),triglyceride(TG),HDL-C and low-density lipoprotein cholesterol(LDL-C),CTRP12 was still an independent in-fluencing factor for the severity of coronary artery disease in the patients with AMI(β=-3.441,OR=0.032,P＜0.05).Conclusion The serum CTRP12 level was significantly decreased in the patients with AMI before PCI,and showed continuous decline on the 3rd day after PCI,but increased on the 5th and 7th day after PCI.CTRP12 should be an independent influencing factor for the severity of coronary artery disease in the patients with AMI.

CD47 is a transmembrane protein widely expressed on cell surface, which is considered as a key molecule for immune escape. With an increasing number of related studies, the role of CD47 and its ligands in immunomodulatory effects has been gradually understood. Recent studies have investigated the role of CD47 in ischemia-reperfusion injury of allogenetic kidney transplantation, rejection and xenotransplantation. Nevertheless, the specific role and the key mechanism remain elusive. In this article, the structure and function of CD47, common CD47 ligands, the relationship between CD47 and kidney transplantation, and the application of CD47 in kidney transplantation were reviewed, the latest research progress of CD47 in kidney transplantation was summarized, and the limitations of current research and subsequent research direction were analyzed, aiming to provide reference for subsequent application of CD47 in allogeneic and kidney xenotransplantation.
