Phakic intraocular lens implantation has become one of the important means of correcting refractive errors today. Among them,the implantable collamer lens(ICL)is favored for its wide range of correction, excellent optical quality, and high safety, but the risks of postoperative complications such as glaucoma and anterior subcapsular opacification still exist. Vault is an important indicator for evaluating the safety after ICL implantation, and its ideal state is crucial for preventing complications. Studies have shown that iris morphology has a significant impact on vault. In order to further optimize surgical outcomes and improve surgical safety, this review comprehensively reviews the research progress of iris-related parameters in ICL implantation and discusses the importance of various parameters in preoperative evaluation and postoperative follow-up.

Objective:To clarify the safety, repair rate, durability, and risk factors for recurrent mitral regurgitation(MR) in patients with Barlow disease(BD) who total thoracoscopic minimally invasive mitral valvuloplasty(TMVP).Methods:Clinical data, mid-term and long-term outcomes of BD patients who underwent TMVP at Guangdong Provincial People's Hospital from January 2009 to June 2022 were retrospectively analyzed. Patients were divided into a group with no MR recurrence(group A) and a group with MR recurrence(group B) according to whether recurrent MR appeared in the postoperative period, and the data of the two groups of patients were compared with each other for the risk factor analysis.Results:The repair rate of TMVP was 98.4%, and no patient died perioperatively. The median follow-up time was 3.1(1.7, 5.2) years, the follow-up rate was 95.8%, and there was no patient died. As of March 2023, 112 patients developed no recurrent MR(group A), 11 patients developed recurrent MR(group B), and 2 patients in group B underwent repeated mitral valve surgery. The left atrial diameter(LAD) and left ventricular end-systolic diameter(LVESD) were higher in group B than in group A patients[LAD: (50.9±7.7)mm vs.(43.7±8.7)mm, P=0.009; LVESD: (37.1±5.5)mm vs.(33.2±4.7)mm, P=0.011], and the percentage of tendon cord rupture was higher in group B than in group A( P=0.022), while the rest of the baseline data were not statistically significant. There was no statistically significant difference between two groups in terms of the use of different surgical techniques, aortic cross-clamp time, cardiopulmonary bypass time, and operative time. Postoperative LAD, postoperative LVESD, and postoperative left ventricular end-diastolic diameter of group B patients were higher than those of group A( P<0.05). There was no statistically significant difference in perioperative and long-term complication rates between the two groups. Multifactorial Cox regression analysis revealed that advanced age( HR=1.049, 95% CI: 0.997-1.103, P=0.066) and large preoperative LVESD( HR=1.168, 95% CI: 1.053-1.295, P=0.003) were the risk factors for postoperative recurrence MR. Conclusion:Total thoracoscopic minimally invasive BD repair is safe, which has a high success rate and good long-term results. Advanced age and large preoperative LVESD are risk factors for recurrent MR in the long term.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Objective:To investigate the incidence of mild cognitive impairment(MCI)and malnutrition among centenarians, as well as to explore the relationship between cognitive impairment and nutritional status.Methods:A cross-sectional study was conducted between November and December 2023, involving 121 elderly individuals aged ≥ 100 years in the Baoshan District of Shanghai.The survey collected general information and included the Ascertain Dementia 8-item Questionnaire(AD8), the Mini Nutritional Assessment Short-Form(MNA-SF), and anthropometric nutritional measurements such as waist circumference(WC), hip circumference(HC), arm circumference(AC), calf circumference(CC), and grip strength.The prevalence of MCI and malnutrition among centenarians was calculated, and the correlation between MCI and MNA-SF scores, along with anthropometric nutritional measurement indicators, was analyzed.Results:The age range of centenarians was between 100 and 105 years, with an average age of 101.0±3.5 years.The majority of centenarians were female(76.9%), illiterate(58.7%), and lived with family members(73.6%).All participants had medical insurance(100%).Most had no history of long-term smoking 118(97.5%), long-term alcohol consumption 108(89.3%), long-term use of health supplements 109(90.1%), long-term tea or coffee habits 114(94.2%), chronic medical conditions 84(69.4%), or family history of dementia 102(84.3%).Additionally, 62(51.2%)reported their health status over the past year as general.According to the AD8 screening results, the negative and positive detection rates of MCI in centenarians were 79(65.3%)and 47(34.7%), respectively.Based on the MNA-SF scoring results, the detection rates of normal nutrition, malnutrition risk, and malnutrition among centenarians were 36(29.8%), 61(50.4%), and 24(19.8%), respectively.There was a statistically significant difference in AC between the non-MCI group and the MCI group among centenarians( t=0.01, P=0.03).The AD8 scores of centenarians were significantly negatively correlated with AC, CC, and MNA-SF scores( r=-0.20, r=-0.26, r=-0.29; all P<0.05). Conclusions:The cognitive function of centenarians is associated with their nutritional status, indicating that higher cognitive abilities correlate with better nutritional status.

Objective To explore the effects of fecal microbiota transplantation on blood uric acid(UA)metabolism,adverse reactions,and gout control in patients with refractory gout.Methods A total of 102 patients with refractory gout in the First Affiliated Hospital of Medical College of Shantou University from June 2020 to June 2023 were randomly divided into two groups,with 51 cases in each group.Control group received benzbromarone and febuxostat treatment,while the observation group re-ceived fecal microbiota transplantation.The gout control status and occurrence of adverse reactions were observed in both groups;intestinal flora,UA,levels of C-reactive protein(CRP),interleukin-18(IL-18),interleukin-6(IL-6),and scores of joint pain,swelling and limited mobility were compared between the two groups before and after treatment.Results Five patients in each group were lost to follow-up.The total gout control rate in the observation group was 89.13％,which was significantly higher than 69.57％ in the control group(P＜0.05).At 4 and 12 weeks after treatment,the levels of Escherichia coli,UA,CRP,IL-18 and IL-6 as well as the scores of joint swelling,pain and limited mobility in the observation group were significantly lower than those in the control group,while the lev-els of Bifidobacterium,Lactobacillus and Bifidobacterium to Escherichia coli(B/E)ratio were signifi-cantly higher than those in the control group(P＜0.01).The total incidence of adverse reactions was 10.87％ in the observation group and 6.52％ in the control group,with no significant between-group difference(P＞0.05).Conclusion Fecal microbiota transplantation has a definite therapeutic effect for patients with refractory gout,which can significantly reduce UA level and control clinical symptoms,and its mechanism may be related to the correction of intestinal flora imbalance.
