Rhegmatogenous retinal detachment(RRD)is a common blinding ophthalmic disease that has always received significant attention in clinical treatment. The foldable capsular buckle(FCB), as a new method for extraocular treatment of RRD, offers“Five Noes” advantages over traditional treatments such as scleral buckling(SB), pars plana vitrectomy(PPV), and pneumatic retinopexy(PR), including no retrobulbar anesthesia, no muscle traction, no scleral fluid release, no intraoperative positioning, and no cryotherapy. This effectively reduces postoperative complications in RRD patients and shortens the operation time. This review aims to investigate the development process and treatment principle of FCB, and focus on its therapeutic advantages, indication selection, efficacy and safety for RRD. It is expected to play a more important role in the treatment of a variety of retinal diseases through technological innovation and application field expansion.

Objective Microcystin-leucine-arginine(MC-LR)exposure induces lipid metabolism disorders in the liver.Secreted frizzled-related protein 5(SFRP5)is a natural antagonist of winglesstype MMTV integration site family,member 5A(Wnt5a)and an anti-inflammatory adipocytokine.In this study,we aimed to investigate whether MC-LR can induce lipid metabolism disorders in hepatocytes and whether SFRP5,which has anti-inflammatory effects,can alleviate the effects of hepatic lipid metabolism by inhibiting the Wnt5a/Jun N-terminal kinase(JNK)pathway. Methods We exposed mice to MC-LR in vivo to induce liver lipid metabolism disorders.Subsequently,mouse hepatocytes that overexpressed SFRP5 or did not express SFRP5 were exposed to MC-LR,and the effects of SFRP5 overexpression on inflammation and Wnt5a/JNK activation by MC-LR were observed. Results MC-LR exposure induced liver lipid metabolism disorders in mice and significantly decreased SFRP5 mRNA and protein levels in a concentration-dependent manner.SFRP5 overexpression in AML12 cells suppressed MC-LR-induced inflammation.Overexpression of SFRP5 also inhibited Wnt5a and phosphorylation of JNK. Conclusion MC-LR can induce lipid metabolism disorders in mice,and SFRP5 can attenuate lipid metabolism disorders in the mouse liver by inhibiting Wnt5a/JNK signaling.

Objective To describe the status and influencing factors of psychological distress in older people living with HIV in Shanghai.Methods Convenience sampling was used to select HIV patients with the age of 50 years old and above who attended follow-up visits at the voluntary counselling & testing clinic in Shanghai Public Health Clinical Center from December 2022 to October 2023.Data were collected using a general information questionnaire,HIV disclosure questionnaire,Distress Thermometer and Lubben Social Network Scale-6.Binary logistic regression was employed to analyze the factors influencing psychological distress.Results The prevalence of psychological distress among 332 participants was 105 cases(31.6％).The top 3 items selected by participants in Psychological Distress Problem List were insurance/financial issues,worry and sleep,relationship with children.Factors associated with a higher level of psychological distress included lower monthly income,not HIV disclosure and higher levels of social isolation.Conclusion Psychological distress among older people living with HIV remains to be further reduced,and it is affected by many factors.Health care providers should pay more attention to psychological distress among older HIV patients,and develop targeted intervention according to relevant influencing factors,aiming to reduce their psychological distress.

Objective To evaluate the effect of parasternal intercostal plane block(PIB)on postopera-tive fatigue in elderly patients undergoing off-pump coronary artery bypass grafting(CABG).Methods A to-tal of 111 elderly patients undergoing elective off-pump CABG in Xuzhou Municipal Central Hospital from May 2021 to January 2023 were selected as the study subjects.The patients were divided into the control group(group C,n=55)and PIB group(group P,n=56)by adopting the random number table method.After induction of anesthesia,the patients in the group P received the ultrasound-guided bilateral PIB,and the group C received the equal volume of normal saline at the same site.The incidence rate of postoperative fatigue syn-drome(POFS)on postoperative 1,3,5,7 d and postoperative 8 weeks,NRS scores immediately after extuba-tion and at postoperative 12,24,48 h,postoperative opioid drugs consumption,ICU stay duration,hospitaliza-tion duration and adverse events occurrence were compared between the two groups.Results Compared with the group C,the incidence rates of POFS on postoperative 1,3,5,7 d and postoperative 8 weeks in the group P were significantly decreased,the NRS scores immediately after extubation and at postoperative 12,24 h in the group P were lower,the postoperative opioid drugs consumption were smaller,the ICU stay duration was shorter,and the differences were statistically significant(P＜0.05).The NRS score at postoperative 48 h and hospitalization duration had no statistical differences between the two groups(P＞0.05).No nerve block re-lated adverse events in the patients appeared during the study period.Conclusion The ultrasound guided PIB could effectively reduce the incidence rate of POFS in elderly patients undergoing off-pump CABG,promote the patients'prognosis and improve the recovery quality of the patients.

Objective:To explore the prognosis efficacy of psycho-cardiological therapy and management on patients with coronary atherosclerosis disease (CAD).Methods:This was a clinical randomized controlled study. This study included inpatients with CAD at the cardiology department in Beijing Anzhen Hospital, Capital Medical University from August 2021 to January 2024. The patients enrolled in this study were asked for basic information, and received measurements for depression, anxiety, sleep quality and living quality by the scales of Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder scale-7 (GAD-7), Athens Insomnia Scale (AIS), EuroQol 5-dimension 5-level (EQ-5D-5L) respectively. The patients were randomly grouped into a regular treatment group and a psycho-cardiological treatment group which included WeChat management or antidepressant/antianxiety medical therapy according to the situation. After the patients discharging from hospital for 2, 4, 12, 24, 48, 72, and 96 weeks, professional cardiovascular doctors would follow up by telephone, WeChat, and outpatient department, including scales (2-48 weeks), and cardiac events (2-96 weeks). Kaplan-Meier survival curve and multivariate Cox proportional hazards model were used for analyzing the association between psycho-cardiological treatment and cardiac events.Results:This study recruited a total of 552 patients with CAD, aged 61.0(54.0, 67.0) years, and 379 (68.7%) were male. There were 279(50.5%) in the regular treatment group and 273(49.5%) in the psycho-cardiological treatment group. After treatment for 4, 12 and 48 weeks, the PHQ-9 score in psycho-cardiological was significantly lower than the regular treatment group; After treatment for 12 weeks, the EQ-5D-5L effective value in psycho-cardiological group was higher than the regular treatment group; After treatment for 2, 4, 12, 24 and 48 weeks, the EQ-5D-5L VAS score in psycho-cardiological group was higher than the regular therapy group (all P<0.05). The Kaplan-Meier survival curve showed that, during the different follow-up periods, the rate of cardiac events in psycho-cardiological treatment group was lower than regular treatment group (log-rank P<0.001). The multivariate Cox proportional hazards model adjusted the factor of age, the psycho-cardiological treatment contributed to reducing the cardiac events rate by 80.3% ( HR=0.197, 95% CI: 0.067-0.582, P=0.003). Conclusion:Psycho-cardiological treatment is beneficial for improving psychological stress, living quality, and reducing cardiac events, and helps to improve prognosis and psycho-cardiological rehabilitation in CAD patients.

The effect of vitamin D supplementation on individuals with autism spectrum disorder (ASD) is inconclusive. We aimed to conduct a meta-analysis of the available randomized controlled trials (RCTs) to explore whether vitamin D supplementation can improve core symptoms and coexisting conditions in children with ASD. Data were obtained by searching the PubMed, Embase, Web of Science, CINAHL and Cochrane Library databases up to February 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Using a random-effects model, mean differences with 95% confidence intervals (CIs) were calculated through a meta-analysis. There were eight RCTs with 266 children with ASD in the present review, among which six RCTs were included in the meta-analysis.Children who received vitamin D supplementation showed a significant improvement in stereotypical behavior scores (pooled mean difference (MD): −1.39; 95% CI: −2.7, −0.07; p = 0.04) with low heterogeneity (I2 = 34%), and there was a trend toward decreased total scores on the Social Responsiveness Scale (SRS) and Childhood Autism Rating Scale (CARS, p = 0.05); however, there were no other significant differences in the core symptoms of ASD and coexisting conditions between groups as measured by the Aberrant Behavior Checklist (ABC). Vitamin D supplementation appears to improve stereotypical behaviors but does not improve other core symptoms and coexisting conditions. Further randomized controlled trials with large sample sizes and individualized doses are needed.

Objective:To investigate the influencing factors of headache degree in migraine patients with patent foramen ovale (PFO).Methods:The clinical data of 124 migraine patients with PFO from January 2013 to June 2019 in Dalian Central Hospital Affiliated to Dalian Medical University were retrospectively analyzed. The right-to-left shunt of PFO was assessed by contrast-enhanced transcranial Doppler (c-TCD); the diameter of PFO, length of PFO tunnel and the presence of atrial septal aneurysm (ASA) were detected by transesophageal echocardiography (TEE); the degree of migraine was assessed by headache impact test-6 (HIT-6) scale. The relations between right-to-left shunt volume of PFO, diameter of PFO and degree of migraine were analyzed by Goodman-Kruskal γ test; the relations between the length of PFO tunnel, ASA and degree of migraine were analyzed by Spearman rank correlation analysis.Results:Among the 124 migraine patients with PFO, the c-TCD test result showed that small shunt volume was in 20 cases, medium shunt volume in 31 cases, and large shunt volume in 73 cases. The TEE test result showed that small foramen ovale in 76 cases, medium foramen ovale in 47 cases, and large foramen ovale in 1 case; long tunnel in 57 cases, and short tunnel in 67 cases; without ASA in 91 cases, and with ASA in 33 cases. The HIT-6 score result showed that some influence in 9 cases, significantly influence in 22 cases, and serious influence in 93 cases. The Goodman-Kruskal γ test result showed that right-to-left shunt volume of PFO and diameter of PFO were positive correlation with degree of migraine ( γ = 0.66, P<0.01; γ = 0.38, P<0.05). The Spearman rank correlation analysis result showed that ASA was positive correlation with degree of migraine ( r = 0.18, P<0.05), while the length of PFO tunnel was negative correlation with degree of migraine ( r = -0.23, P<0.05). Conclusions:The right to left shunt amount of PFO, diameter of PFO and the presence of ASA are positive correlation with degree of migraine, while the length of PFO tunnel is negative correlation with degree of migraine.
