OBJECTIVE To explore the risk signals of Fluocinolone acetonide intravitreal implants and promote safe and rational drug use for patients. METHODS Based on the data from the Hainan Province Franchised Drug Adverse Reaction Monitoring Subsystem （hereinafter referred to as the “Franchised Drug Monitoring System”） and the FDA Adverse Event Reporting System （FAERS）， the adverse drug reaction （ADR）/adverse drug event （ADE） reports of Fluocinolone acetonide intravitreal implants were coded by using system organ classification and preferred terminology， and relevant patient information was collected. Risk signal mining was carried out by using the reporting odds ratio （ROR） method and the comprehensive standards method of the UK Medicines and Healthcare Products Regulatory Agency （hereinafter referred to as the “MHRA method”）. RESULTS Among the 72 reports of Fluocinolone acetonide intravitreal implants received by the Franchised Drug Monitoring System， the ratio of male to female was 1∶1.4， the patient’s age was mainly distributed between 18 and 64 years old； ADR/ADE affected 5 systemic organs， with eye organ diseases accounting for 87.7%； among them， there were 9 new and general ADR reports （12.5%） and 4 severe ADR reports （5.6%）； ROR method and MHRA method both identified three risk signals： cataracts， glaucoma， and high intraocular pressure. Among the 244 reports received by the FAERS database， the ratio of male to female was 1∶1.5； ADR/ADE damage affected 10 systemic organs， with 46.1% suffering from various injuries， poisoning， and operational complications， and 32.0% suffering from product problems； there were 20 severe ADR reports （8.2%）； ROR method and MHRA method both identified 19 risk signals， including implantation complications， medication system issues， etc. CONCLUSIONS When using Fluocinolone acetonide intravitreal implants in clinical practice， in addition to paying attention to eye ADR/ADE such as high intraocular pressure， cataracts， and glaucoma， attention should also be paid to the potential risks caused by ADE due to product quality and unreasonable use.

Objective To explore the relationship of the systemic immune-inflammation index (SII) with heart failure incidence in elderly people with hypertension and its nursing implications. Methods According to the data of the National Health and Nutrition Examination Survey (NHANES) database from 1999 to 2010, a total of 5 607 hypertension patients aged 60 and above were screened out and divided into heart failure group with 437 cases and non-heart failure group with 5 170 cases. All the participants were divided into Q₁ to Q₄ groups based on their SII levels by using the quartile method, with Q₁ as the reference group. After gradually adjusting for potential confounding factors, the differences in prevalence rate of heart failure among four groups were explored by Logistic regression analysis, and subgroup analyses were conducted as well. Results There were significant differences in race, age, education level, income level, smoking history, drinking history, body mass index (BMI), C-reactive protein, estimated glomerular filtration rate (eGFR), hemoglobin, diabetes history and coronary heart disease history between the two groups (P < 0.05). Compared with the non-heart failure group, the heart failure group had significant lower lymphocyte and platelet counts, while the neutrophil count and SII were significantly higher (P < 0.05). The result of multiple Logistic regression analysis showed a positive correlation between the increase of SII and the prevalence rate of heart failure (P < 0.05). After adjusting for related confounding factors, the values of odds ratio (OR) and 95% confidence interval (95%CI) for prevalence rate of heart failure in patients with SII from the second to the fourth quartiles were 0.80 (0.57 to 1.11), 1.14 (0.84 to 1.56) and 1.38 (1.02 to 1.87) respectively (P_trend=0.006). Subgroup analyses were carried out according to gender, diabetes, coronary heart disease, hyperlipidemia and eGFR, and the results showed that among women without coronary heart disease, with eGFR≤90 mL/(min·1.73 m²) and with or without hyperlipidemia, participants with the highest quartile of SII (Q₄) had a significant higher risk of heart failure than those with Q₁ (P_trend < 0.05). Conclusion SII may be independently associated with the prevalence rate of heart failure in elderly people with hypertension, and has guiding significance for clinical and nursing work.

Objective: To explore the role of mobile phone addiction and anxiety symptoms in the relationship between childhood psychological abuse and depressive symptoms among college students, in order to provide a basis for mental health promotion. Methods: From February to May 2023, a stratified random sampling method was used to select 1 799 freshmen to juniors from a university in Wuhu City, Anhui Province. The questionnaire survey was conducted using the 2-item Patient Health Questionnaire (PHQ-2), Child Psychological Maltreatment Scale (CPMS), Mobile Phone Addiction Tendency Scale (MPATS), 2-item General Anxiety Disorder (GAD-2). Correlations among each variable were analyzed, and the chain mediating effect of mobile phone addiction and anxiety symptoms was explored. Results: The detection rate of depressive symptoms among college students was 9.7%, and the positive detection rate of childhood psychological abuse was 28.6%. Depressive symptoms were positively correlated with childhood psychological abuse, mobile phone addiction and anxiety symptoms ( r =0.28, 0.32, 0.27, P <0.01). Childhood psychological abuse was positively correlated with mobile phone addiction and anxiety symptoms ( r =0.29, 0.71, P <0.01). Mobile phone addiction and anxiety symptoms were positively correlated ( r =0.30, P <0.01). Childhood psychological abuse could effectively predict depressiove symptoms, mobile phone addiction and anxiety symptoms ( β =0.08, 0.06, 0.66, P <0.01). Mobile phone addiction and anxiety symptoms had a chain mediating effect between childhood psychological abuse and depression symptoms, with a total indirect mediating effect (effect=25.27%, P <0.05), accounting for 72.44% of the total effect. Conclusions Mobile phone addiction and anxiety symptoms play a chain mediating role between childhood psychological abuse and depressive symptoms. Focusing on childhood psychological abuse, mobile phone addiction and anxiety among college students are beneficial for depression symptoms prevention.

Objective:To analyze the effect of insulin aspart on the islet cell secretion function, ultrasound imaging indicators and maternal and infant outcome in patients with gestational diabetes mellitus (GDM).Methods:The clinical data of 120 patients with GDM in Beijing Obstetrics and Gynecology Hospital Affiliated to Capital Medical University from February 2017 to July 2019 were retrospectively analyzed. Among them, 60 cases were treated with insulin aspart (observation group) and 60 cases were treated with biosynthetic human insulin (control group). The efficacy indexes, ultrasound imaging indexes and maternal and infant outcome were compared.Results:The 2 h postprandial blood glucose (2 h PBG) after breakfast on the third and fifth day of treatment in observation group was significantly lower than that in control group: (6.85 ± 0.87) mmol/L vs. (7.47 ± 1.35) mmol/L and (6.24 ± 0.59) mmol/L vs. (6.60 ± 0.87) mmol/L, and there was statistical difference ( P<0.01); there was no statistical difference in 2 h PBG after breakfast on the first day of treatment and after lunch and dinner on the first, third and fifth day of treatment between 2 groups ( P>0.05). The homeostasis model assessment-insulin resistance index (HOMA-IR) after treatment in observation group was significantly lower than that in control group (2.57 ± 0.25 vs. 3.00 ± 0.35), the homeostasis model assessment- β cell function index (HOMA-β) was significantly higher than that in control group (72.45 ± 12.33 vs. 63.66 ± 10.72), and there were statistical differences ( P<0.01). There were no statistical differences in pre-lunch blood glucose, pre-lunch initial insulin amount, pre-lunch final insulin amount and blood glucose target time between 2 groups ( P>0.05); the incidence of pre-meal hypoglycemia in observation group was significantly lower than that in control group: 8.33% (5/60) vs. 23.33% (14/60), and there was statistical difference ( P<0.05). The umbilical artery and renal artery resistance index (RI), maximum systolic blood flow velocity and end-diastolic blood flow velocity ratio (S/D) after treatment in observation group were significantly lower than those in control group (RI: 0.49 ± 0.16 vs. 0.59 ± 0.15 and 0.69 ± 0.17 vs. 0.76 ± 0.12; S/D: 2.09 ± 0.22 vs. 2.38 ± 0.26 and 5.17 ± 0.45 vs. 5.77 ± 0.63), and there were statistical differences ( P<0.01 or <0.05). There were no statistical differences in gestational age, delivery mode, neonatal body weight and the incidences of macrosomia, neonatal hypoglycemia and neonatal referral between 2 groups ( P>0.05). Conclusions:Insulin aspart can significantly improve the islet cell secretion function and ultrasound imaging indexes in the treatment of GDM, and can reduce the risk of pre-meal hypoglycemia, but the effect on maternal and infant outcome remains to be explored.

Objective:To investigate the mid-term efficacy of Dynesys internal fixation and posterior lumbar interbody fusion (PLIF) in the treatment of grade I degenerative lumbar spondylolisthesis.Methods:From June 2014 to June 2016, 68 cases, in which 35 males and 33 females aged from 44-74 (55.3±7.5), of grade I degenerative lumbar spondylolisthesis treated using Dynesys internal fixation were retrospectively analyzed. There were 8 cases of L 3, 52 cases of L 4 and 8 cases of L 5 with an average visual analogue scale (VAS) of 4.5±2.1. At the same time, 72 patients were treated with posterior lumbar interbody fusion (PLIF). There were 37 males and 35 females aged from 46-76 (56.8±7.2), with 9 cases of L 3, 53 cases of L 4 and 10 cases of L 5. The VAS of this group was 4.4±2.3. The operative time, intraoperative blood loss, postoperative drainage volume and complications were compared between the two groups. Range of motion (ROM), disc height of stable segment and upper adjacent segment, adjacent segment degeneration between the two groups were evaluated. ASD, Oswestry disability index (ODI) score and Japanese Orthopaedic Association (JOA) score were also compared between the two groups. Results:The patients in both groups were followed up. The follow-up time of Dynesys group was 50-74 months, average 64.2±18.3 months, and the follow-up time of PLIF group was 55-79 months, average 65.2±15.5 months. The operation time [(120.5±21.0) min vs. (132.5±27.0) min, t=2.924, P=0.004], intraoperative bleeding [(312.5±80.7) ml vs. (352.5±84.5) ml, t=2.861, P=0.005] and postoperative drainage [(120.3±45.8) ml vs. (140.2±50.2) ml; t=2.446, P=0.016] in Dynesys group were significantly better than those in PLIF group. The differences were statistically significant. There was no significant difference in postoperative ROM of stable segment, ROM of upper segment, disc height of stable segment and adjacent segment between the two groups before operation. At 5 years postoperatively, there was statistically significant difference between the stable segment ROM (4.3°±1.6° vs. 0; t=22.809; P<0.001) and the upper segment ROM (10.5°±2.1° vs. 12.8°±2.2°; t=6.329, P<0.001). At 5 years postoperatively, ODI scores of the two groups were (11.25%±8.12%, 16.53%±9.23%), and JOA scores were (22.60±2.20, 19.01±2.34), which were significantly improved compared with those before surgery, with statistically significant differences (ODI: t=3.585, P<0.001; JOA: t=9.340, P<0.001). There was no significant difference in the incidence of symptomatic ASD between the two groups (8.8% vs. 16.7%, χ2=1.284, P=0.257) , but there was significant difference in the incidence of X-ray ASD between the two groups (2.9% vs. 13.9%, χ2=4.043, P=0.044) . Conclusion:Compared with PLIF, Dynesys internal fixation for degenerative lumbar spondylolisthesis is a minimally invasive, safe and effective surgical method to retard ASD; Compared with PLIF, adjacent segment degeneration can be reduced using Dynesys internal fixation.
