Objective To analyze the consistency of individual examination diagnosis with terminologies expressed in the conclusion report of physical examinations by the chief inspection physician. Methods Based on the clinical classifications used in the Guidelines on Prevention and Treatment of Blood Lipid Abnormality for Chinese Adults, and related terminology descriptions of Dyslipidemias that were actually used in four-item blood lipid examinations diagnosis, a lexicon database of Hyperlipidemias was constructed with 39 terms used in the four-item blood lipid examination diagnosis and chief physician conclusions. Totally 11953 electronic chief physician inspection reports from 8 health check-up institutions were included. We investigated the terms of lexicon database using word frequency analysis method, calculated the positive rate in the diagnosis of four single examinations of serum lipid and the positive rate in the chief physician's conclusion. Consistency of chief physician's conclusion with single examination diagnosis was analyzed by Kappa test. Results (1) Among the 39 terms of lexicon database, there are 18 nonstandard terms used in single examination diagnosis, accounted for 46％ of all terms; (2) In word frequency analysis, there are only 1％ of terms that corresponded to clinical classifications of Hyperlipidemias accurately;(3) The positive rate of Hyperlipidemias in serum lipid four single examinations diagnosis was 47％, the positive rate of physician diagnosis was 35％. The consistency analysis of chief physician conclusions with single examination diagnosis showed Kappa=0.71(P<0.01). Conclusions Although the final conclusion written by the chief physician was not using standard terms strictly, most of synonymous terminology expressed in the physician conclusion is normative, which enabled the construction of lexicon database and text mining. Whether the single examination diagnosis are consistent with physician conclusions can be an evaluation indicator to assess the quality of chief physician conclusions for physical examinations. Kappa>0.75 may be suggested as a favorable value.

Objective: To analyze the potential categories and influencing factors of the compliance trajectory of orthokeratology lenses (OK lens) in myopic children and adolescents, so as to provide a basis for dynamic and accurate intervention of OK lens compliance in myopic children and adolescents. Methods: From January to June 2024, 310 myopic children and adolescents wearing OK lens were selected as research subjects from the Ophthalmology Medical Center of Cangzhou Central Hospital using a convenient sampling method. Data were collected at four time points: when the glasses were first fitted (T0), 2 weeks after fitting (T1), 1 month later (T2), 3 months later (T3), and 6 months later (T4). The data collection methods included general information questionnaires, compliance surveys for OK lens wearers, the Behavior Rating Inventory of Executive Function-Self-report Version (BRIEF-SR), family support scales, and a self-made questionnaire on myopia control attitudes. A growth mixed model was used to identify the trajectory categories of compliance with OK lens wearing among myopic children and adolescents, and multiple Logistic regression analysis was employed to examine the influencing factors. Results: The compliance with OK lens among myopic children and adolescents were roughly divided into four developmental trajectories: C1 exemplary adherent (58 cases, 18.71%), C2 gradual progressor (130 cases, 41.94%), C3 fluctuating (85 cases, 27.42%), and C4 stubborn low follower (37 cases, 11.94%). Multivariate Logistic regression analysis showed that, with C1 group as the reference, age (C3, OR = 0.74 ), parental education level (C4, OR =0.67), executive function (C2, OR =0.69; C4, OR =0.44), family support (C3, OR =0.75) and myopia control attitude (C2, OR =0.39) were all influencing factors for the compliance trajectory of OK lens; with C2 group as the reference, age (C3, OR = 0.55 ), parental education level (C3, OR =0.34; C4, OR =0.64), executive function (C3, OR =0.77), and family support (C4, OR =0.58) were all influencing factors for the compliance trajectory of OK lens; with C3 group as the reference, age (C4, OR = 0.68 ), and myopia control attitude (C4, OR =0.44) were both influencing factors for the compliance trajectory of OK lens ( P <0.05). Conclusions The compliance of wearing OK lens in children and adolescents with myopia can be roughly divided into four trajectories, and there is group heterogeneity. Dynamic and precise compliance intervention strategies should be given based on different trajectories and influencing factors.

OBJECTIVE: To explore the molecular pathogenesis for a pedigree affected with hereditary coagulation factor XII (FXII) deficiency. METHODS: Potential variant of the F12 gene was analyzed by PCR and Sanger sequencing. Expression plasmids were constructed by site-directed mutagenesis based on the wild-type and transiently transfected into 293T cells. FXII:C and FXII:Ag of the expression products were determined in the supernatant and cell lysate. Western blotting was used to verify the identify of the protein. RESULTS: Gene sequencing revealed that the proband has carried 46TT genetype and heterozygous p.Glu502Lys variants in exon 13, and a heterozygous p.Gly542Ser variant in exon 14 of the F12 gene. Transfection experiment suggested that the FXII:C and FXII:Ag of p.Glu502Lys variant in the supernatant were 28% and 24%, compared with the wild-type (100%) and FXII:Ag of cell lysates was 39% compared to the wild-type (100%). The FXII:C and FXII:Ag of p. Gly542Ser variant in the supernatant were 32% and 17% and the FXII:Ag of cell lysates was 59%. CONCLUSION The 46TT genetype, p.Glu502Lys and p.Gly542Ser variants of the F12 gene probably underlie the low FXII level in the proband. As shown by in vitro experiment, the p.Glu502Lys and p.Gly542Ser variants can both inhibit the synthesis and secrection of the FXII protein.

Objective:To investigate the early and mid-term outcomes of aortic endovascular remodeling device (AERD) for Stanford type A aortic dissection (TAAD) in type Ⅱhybrid surgery, and to evaluate its clinical efficacy.Methods:46 patients with TAAD, including 14 females and 32 males, participated in the single-center clinical trial of West China Hospital of Sichuan University and underwent type II hybrid surgery (Bentall / ascending aorta replacement + AERD implantation) from February 2021 to October 2023. The safety and efficacy of AERD in type Ⅱ hybrid surgery for TAAD were estimated by clinical indicators (postoperative mortality, cardiovascular and cerebrovascular accidents, paraplegia, ischemia), and blood flow condition (volume of the true and false lumen, and suprachial branches).Results:Three patients (6.52%) died during the follow-up period, and the operation-related mortality was 4.35% (2/46). The remaining 43 patients were followed up for an average of (25.53±9.60) months. There were two cases (4.35%) of stroke after the operation, and paraplegia, acute renal insufficiency, and other severe complications were not noticed. The blood flow of the superior branch of the aortic arch was unobstructed, and there was no significant difference in the blood flow of the branch before the operation and at each follow-up time point. Compared to the pre-operation, the true lumen volume of the stent part increased by 59.0% and the false lumen volume decreased by 82.4%.Conclusion:AERD is a safe and effective alternative in type II hybrid surgery for acute TAAD, which is helpful in improving perioperative and short- and long-term survival rates and clinical outcomes.

Objective : To investigate the effect of CD147 on reducing hydrogen peroxide - induced oxidative stress injury in prostate cancer LNCaP cells. Methods : The lentiviral system was used to establish a CD147 ⁃silencing prostate cancer cell model (LNCaP/shCD147 cells) and a negative control cell (LNCaP/Scramble cell) , and RT⁃qPCR was performed for verification. By detecting the activity of reactive oxygen species ( ROS) , superoxide dismutase (SOD) , glutathione peroxidase ( GSH⁃PX) and malondialdehyde ( MDA) in LNCaP/shCD147 and LNCaP/Scramble cells to verify the changes of oxidative stress and antioxidant enzymes in prostate cancer cells after silencing CD147 ; hydrogen peroxide( H2 O2 ) was added to the cells and the cell growth was detected by CCK⁃8 ; Western blot was used to detect the expression changes of nuclear factor E2 related factors (Nrf2) and heme oxygenase⁃1 (HO⁃1) to verify the relationship between the oxidative stress that occurs in prostate cancer cells after silencing CD147 and the PI3K/AKT signaling pathway. Results : Successfully constructed a CD147⁃silencing prostate cancer cell model. Compared with LNCaP/Scramble cells , the expression of CD147 in mRNA was reduced (P <0. 01) . The results of oxidative stress showed that the content of ROS and MDA in cells increased after silencing CD147 (ROS , P < 0. 01 ; MDA , P < 0. 05) , while the activities of SOD and GSH⁃PX decreased(P < 0. 01) , indicating that after silencing CD147 , LNCaP/shCD147 cells undergo oxidative stress. In addition , with the increase of H2O2 concentration , the survival rate of LNCaP/shCD147 group cells decreased (P < 0. 01) . After inhibiting the PI3K/AKT signaling pathway , the expressions of Nrf2 and HO⁃1 in the LNCaP/shCD147 group were reduced (P < 0. 01) , indicating that CD147 inhibits the oxidative stress injury of prostate cancer cells through the PI3K/AKT pathway. Conclusion CD147 can reduce the oxidative stress damage of PCa cells , and its inhibitory mechanism may be related to the PI3K/AKT signaling pathway.
