AIM:To investigate the visual quality and stereopsis after the implantation of PanOptix trifocal intraocular lens(TFNT00).METHODS: A prospective clinical study was conducted. A total of 36 cataract patients(50 eyes)who underwent phacoemulsification combined with TFNT00 implantation in Jinan Mingshui Eye Hospital from November 2022 to April 2024 were selected. They were followed up until 3 mo after the operation. The uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA), uncorrected near visual acuity(UCNVA), objective scatter index(OSI), modulation transfer function cut off(MTF-cut-off), Strehl ratio(SR)and 100%, 20%, 9% contrast visual acuity(CVA)were observed. The binoptometer was used to collect the patients' far and near stereopsis acuities. The defocus curve was drawn after the operation; the Chinese version of the VF-14 Visual Function Index Scale was used to evaluate the visual quality and satisfaction after the operation.RESULTS: There were statistically significant differences in the UCDVA, UCIVA and UCNVA of the patients at different time after the operation(all P<0.05). The transition of the defocus curve was gentle between +0.5--3.0 D after the operation. The OSI value at 3 mo postoperatively after the operation was significantly lower than that before the operation(P<0.01), and the MTF-cut-off, SR, 100% CVA, 20% CVA and 9% CVA were significantly improved than those before operation(all P<0.01). The far and near stereopsis acuities of 34 patients were abnormal before the operation. The far stereopsis acuities of the patients who underwent bilateral eye surgeries were all normal after the operation, and the near stereopsis acuity of 12 patients was normal. Among the patients who underwent unilateral eye surgeries, the far stereopsis acuities of 13 patients were normal, and the near stereopsis acuities of 11 patients were normal. The far and near stereopsis acuities of the patients who underwent bilateral eye surgeries were significantly better than those patients who underwent unilateral eye surgeries.CONCLUSION: The PanOptix trifocal intraocular lens can provide patients with good full-range visual acuity. The stereopsis of the patients with bilateral implants is better than that of the patients with unilateral implants. The overall visual quality and satisfaction of the patients after the operation are relatively high.

【Objective】 To investigate the relationship between the initial serum ammonia level and the risk of ICU and hospital mortalities in critically ill patients without hepatic disease. 【Methods】 A retrospective cohort study was conducted among patients admitted to the eICU Collaborative Research Database (eICU-CRD) for a single admission who had serum ammonia test records within 48 hours of the first ICU admission and had no hepatic disease. The age, sex, ethnicity, Acute Physiologic and Chronic Health Evaluation Ⅳ score (APACHE Ⅳ score), treatment methods, complications, and outcomes were extracted. Univariable and multivariable Logistic regression were used to analyze the relationship between serum ammonia level and the risk of mortality. Interactions were used to analyze whether the relationship between serum ammonia level and the risk of mortality differed in subgroups of APACHE Ⅳ scores, age, sex, and ethnicity; subgroup analyses were made. 【Results】 A total of 1 674 patients were included. The multivariable Logistic regression showed that for every 10 μg/dL increase in ammonia, the risk of ICU death increased by 6.9% (OR=1.069, 95% CI: 1.036-1.104), and the risk of hospital death increased by 4.6% (OR=1.046, 95% CI: 1.017-1.076). The risk of ICU death was 1.7 times greater in patients with initial ammonia level of 49-82 μg/dL than in those with <49 μg/dL (OR=1.700, 95% CI: 1.165-2.482), the risk of ICU death was 2.862 times greater in patients with a level of ≥82 μg/dL compared to those with <49 μg/dL (OR=2.862, 95% CI: 1.792-4.570), and the risk of hospital death was 1.844 times higher in the ≥82 μg/dL group than in the <49 μg/dL group (OR=1.844, 95% CI: 1.213-2.804). There were no significant differences between initial ammonia level and the risk of mortalities in different subgroups of APACHEⅣ scores, age, sex, or ethnicity. 【Conclusion】 In critically ill patients without hepatic disease, elevated initial serum ammonia level after ICU admission is associated with a high risk of ICU and hospital mortality.

【Objective】 To investigate the clinical efficacy and significance of percutaneous cement discoplasty (PCD) in treating elderly patients with spinal instability and vacuum phenomenon on imaging. 【Methods】 We retrospectively analyzed 27 patients with spinal instability and vacuum phenomenon on imaging who underwent PVABC between June 2019 and September 2022. We recorded the surgery duration, bone cement usage, intraoperative bleeding, and total hospitalization time. We evaluated the improvement in pain and lumbar function by comparing pre- and postoperative visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, and lumbar Japanese Orthopedic Association (JOA) scores. We also compared the change in intervertebral height and the distribution rate of bone cement in the intervertebral space by pre- and postoperative imaging data. 【Results】 All the 27 patients who underwent PCD had effective follow-up. The mean hospitalization time was (4.2±1.85) days, and the mean surgery duration was (32.3±4.51), (53.6±12.17), (74.4±6.33), and (90.0±10.36) minutes for single-, double-, triple-, and quadruple-level procedures, respectively. The intraoperative bleeding volume ranged from 2 to 13 mL, which was significantly lower than that of traditional intervertebral fusion surgery. Postoperative VAS pain scores, ODI scores, and JOA scores were significantly improved compared to those before surgery. In terms of imaging, the intervertebral height of the patients improved after surgery, and the distribution of bone cement in the intervertebral space was relatively good in the operated segments. Mechanical stability of the spine was restored. 【Conclusion】 For patients who are not suitable for open surgery due to severe complications, PCD is a feasible treatment option.

Objective:To explore the relationship between blood urea nitrogen to creatinine ratio and frailty in the elderly aged ≥65 years in 8 longevity areas in China.Methods:Participants were recruited from the Healthy Aging and Biomarkers Cohort Study. Based on baseline information about blood urea nitrogen and risk for frailty obtained at follow-up of the participants, blood urea nitrogen to creatinine ratio was classified according to quintiles, Cox proportional hazard regression models were used to analyze the association between blood urea nitrogen to creatinine ratio and frailty.Results:A total of 1 562 participants aged (81.0±17.0) years were included, in whom 814 (52.1%) were men, and 258 frailty events occurred during a mean follow-up of (3.73±1.43) years. Cox proportional hazards model showed that after adjusting for relevant confounders, compared with the participants in the lowest quintile group ( Q1), the risk for frailty decreased by 36%, 44%, and 40% in the participants in the third quintile group ( Q3), the fourth quintile group ( Q4) and the highest quintile group ( Q5) respectively [hazard ratio ( HR)=0.64, 95% CI: 0.43-0.94; HR=0.56, 95% CI: 0.38-0.84; HR=0.60, 95% CI: 0.41-0.88]. The risk for frailty decreased by 20% for every unit standard deviation increase in blood urea nitrogen to creatinine ratio ( HR=0.80, 95% CI: 0.70-0.91). Moreover, blood urea nitrogen to creatinine ratio and the risk for frailty showed a nearly linear dose-response relationship. Conclusions:The increase in blood urea nitrogen to creatinine ratio was associated with higher risk for frailty. Maintaining high blood urea nitrogen to creatinine ratio is important for the prevention of frailty in the elderly.

Objective:To observe the effect of epigallocatechin gallate (EGCG) on intestinal injury in sepsis, and to investigate the effect on endoplasmic reticulum stress (ERS) apoptotic pathway.Methods:Sixty male SD rats were selected and divided into five groups according to the randomized numeric table method: the sham operation group (Sham group), the cecal ligation and puncture sepsis group (CLP group), the sepsis+EGCG low-dose group (postoperative intraperitoneal injection of EGCG 25 mg/kg, EL group), the sepsis+EGCG medium-dose group (postoperative intraperitoneal injection of EGCG 50 mg/kg, EM group), and sepsis+EGCG high-dose group (postoperative intraperitoneal injection of EGCG 75 mg/kg, EH group), each group with 12 rats. The rats in each group were executed 24 h after modeling and specimens were collected. Inflammatory factors in serum were detected by enzyme-linked immunosorbent assay. Pathological changes of ileum were observed under light microscope after hematoxylin eosin staining and evaluated according to the Chiu's score. The intestinal tissues were stained for tight junction protein-1 (CLDN1, Claudin-1), phosphorylated protein kinase R-like endoplasmic reticulum kinase (p-PERK), protein kinase RNA-like endoplasmic reticulum kinase (PERK), cysteinyl aspartate specific protein-12 (Caspase-12), and CCAAT enhancer-binding protein homologous protein (C/EBP-homologous protein antibody, CHOP) protein expression was detected by protein immunoblotting assay. The positive areas of Claudin-1, p-PERK, CHOP, and Caspase-12 in intestinal tissue were detected by immunohistochemistry.Results:Compared with the Sham group, the serum levels of interleukin (IL)-1β, IL-6, tumor necrosis factor-α, and the Chiu's score of rats in the CLP group were increased (all P<0.05). The ileal mucosal tissues showed reduced expression of Claudin-1, ERS apoptosis-associated protein p-PERK, CHOP, and Caspase-12 expression were increased (all P<0.05). Compared with the CLP group, the intestinal injury in rats was alleviated after the administration of low, medium and high dose EGCG intervention (all P<0.05). The serum inflammatory factor level, Chiu's score and the protein expression level and positive area of ERS apoptosis-related proteins, p-PERK, CHOP, and Caspase-12 in the small intestinal tissues of EL group were further reduced compared with that of the CLP group were further decreased, and EM group was further decreased than EL group, and EH group was further decreased than EM group (all P<0.05). The protein expression level and positive area of Claudin-1 in small intestinal tissues of EL group were further increased compared with that of CLP group (both P<0.05), and EM group was further increased compared with that of EL group and EH group was further increased compared with EM group (all P<0.05). Conclusions:EGCG may have a protective effect on intestinal injury in septic rats by inhibiting the activation of ERS-induced apoptotic pathway, and the efficacy of high-dose EGCG has a better effect.

Objective:To develop a risk prediction model for identifying bronchopulmonary dysplasia (BPD) associated pulmonary hypertension (PH) in very premature infants.Methods:This was a retrospective cohort study. The clinical data of 626 very premature infants whose gestational age <32 weeks and who suffered from BPD were collected from October 1 st, 2015 to December 31 st, 2021 of the Seventh Medical Center of the People′s Liberation Army General Hospital as a modeling set. The clinical data of 229 very premature infants with BPD of Hunan Children′s Hospital from January 1 st, 2020 to December 31 st, 2021 were collected as a validation set for external verification. The very premature infants with BPD were divided into PH group and non PH group based on the echocardiogram after 36 weeks′ corrected age in the modeling set and validation set, respectively. Univariate analysis was used to compare the basic clinical characteristics between groups, and collinearity exclusion was carried out between variables. The risk factors of BPD associated PH were further screened out by multivariate Logistic regression, and the risk assessment model was established based on these variables. The receiver operating characteristic (ROC) area under curve (AUC) and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the model′s discrimination and calibration power, respectively. And the calibration curve was used to evaluate the accuracy of the model and draw the nomogram. The bootstrap repeated sampling method was used for internal verification. Finally, decision curve analysis (DCA) to evaluate the clinical practicability of the model was used. Results:A total of 626 very premature infants with BPD were included for modeling set, including 85 very premature infants in the PH group and 541 very premature infants in the non PH group. A total of 229 very premature infants with BPD were included for validation set, including 24 very premature infants in the PH group and 205 very premature infants in the non PH group. Univariate analysis of the modeling set found that 22 variables, such as artificial conception, fetal distress, gestational age, birth weight, small for gestational age, 1 minute Apgar score ≤7, antenatal corticosteroids, placental abruption, oligohydramnios, multiple pulmonary surfactant, neonatal respiratory distress syndrome (NRDS)>stage Ⅱ, early pulmonary hypertension, moderate-severe BPD, and hemodynamically significant patent ductus arteriosus (hsPDA) all had statistically significant influence between the PH group and the non PH group (all P<0.05). Antenatal corticosteroids, fetal distress, NRDS >stage Ⅱ, hsPDA, pneumonia and days of invasive mechanical ventilation were identified as predictive variables and finally included to establish the Logistic regression model. The AUC of this model was 0.86 (95% CI 0.82-0.90), the cut-off value was 0.17, the sensitivity was 0.77, and the specificity was 0.84. Hosmer-Lemeshow goodness-of-fit test showed that P>0.05. The AUC for external validation was 0.88, and the Hosmer-Lemeshow goodness-of-fit test suggested P>0.05. Conclusions:A high sensitivity and specificity risk prediction model of PBD associated PH in very premature infants was established. This predictive model is useful for early clinical identification of infants at high risk of BPD associated PH.

Objective To investigate the distribution and imaging manifestations of extrapulmonary bronchogenic cyst(BC)and to make differential diagnosis.Methods The data of 32 patients with extrapulmonary BC confirmed by pathology were collected.The lesion location,CT and MRI findings were analyzed and summarized.All patients underwent plain CT scan,and 27 of them underwent enhanced CT scan.Three patients underwent MRI plain and enhanced scan.Results Of the 32 patients,24 cases were mediastinal BC including 20 cases in the anterior mediastinum and other 4 cases in the posterior mediastinum.8 cases were ectopic BC,including 2 cases in the upper chest wall,4 cases in the gastric cardia,1 case in the greater curvature of the stomach,and 1 case in the left adre-nal gland.All lesions were single with clear boundary.The lesions were mainly round in shape(22 cases),and a few were flat/"D"shape(10 cases).There were no significant differences in the included signs between mediastinal BC and ectopic BC(P＞0.05).Nodular calcification of cyst wall was found in 2 cases.There were 4 cases with CT value＜20 HU and other 28 cases with CT value≥20 HU.The enhanced CT scan in 27 cases showed non-or mild enhancement.MRI showed hypointensity on T1WI in 2 cases,isointensity on T1WI in 1 case,hyperintensity on T2WI in 3 cases,and obvious enhancement on T1WI enhanced scan in 1 case.In addition,30 cases(93.7％)were misdiagnosed as thymic cyst(8 cases),thymoma(12 cases),neurogenic tumor(4 cases),ganglioneuroma(4 cases)and gastric stromal tumor(2 cases).Conclusion Extrapulmonary BC is rare,and most of the lesions are located near the central axis of the body with no obvious enhancement and sometimes cyst wall calcification,which has certain value for clinical diagnosis.

Objective:To compare the safety and efficacy of high-dose- rate interstitial brachytherapy and particle implantation radiotherapy in the treatment of lymph nodes with pelvic metastases in the field after external radiotherapy.Methods:Clinical data of 42 patients with residual or newly metastatic pelvic lymph nodes after radiotherapy at Cangzhou Integrated Traditional Chinese and Western Medicine Hospital who met the inclusion criteria from January 2017 to April 2020 were retrospectively analyzed. Among them, 12 patients were male and 30 females, aged 39-82 years, (61.6±9.64) years on average. According to the treatment method, all patients were divided into the high-dose-rate interstitial brachytherapy group ( n=18) and particle implantation radiotherapy group ( n=24). During 3-year follow-up, the local control rate (LCR), incidence of complications and overall survival (OS) were compared between two groups. Age and operation time conforming to normal distribution were analyzed by t-test. The remaining indexes were analyzed by the Chi-square test or Fisher's exact test. The OS and LCR were calculated by Kaplan-Meier method. Results:There was no significant difference in baseline data between two groups (all P>0.05). The operation time in the high-dose- rate interstitial brachytherapy group was longer than that in the particle implantation radiotherapy group [(66.39±11.07) : (45.75±9.19) min, P<0.001]. During subsequent follow-up, there was no significant difference in the LCR between two groups (1-year LCR 88.9% vs. 87.5%, P=0.927; 2-year LCR 72.2% vs. 62.5%, P=0.874). There was no significant difference in the median OS between two groups (31.6 vs. 29.8 months, P=0.798). There was no significant difference in the incidence of early complications between two groups [ (4/18) vs. 5/24 (20.8%), P=1.000]. No late complications observed. Conclusion:High-dose- rate interstitial brachytherapy yields equivalent efficacy and safety to particle implantation radiotherapy in the treatment of lymph nodes with pelvic metastases.
