AIM: To assess the effectiveness of selective laser trabeculoplasty(SLT)in the treatment of primary open angle glaucoma(POAG).METHODS:Totally 24 patients(33 eyes)with POAG who had poor control of intraocular pressure(IOP)from June 2022 to December 2023 were included in this retrospective study, and all of them were treated with SLT. Furthermore, the IOP, mean deviation(MD), mean sensitivity(MS), and the thickness and vascular density(VD)of optic disc nerve layer were compared after treatment. RESULTS: There were significant reducion in IOP at 1, 3, 6, 12 mo after treatment(all P<0.001). There were no statistically significant differences in MD and MS before treatment and at 6 and 12 mo after treatment(all P>0.05), and there were no statistical significant differences in the thickness and VD of optic disc(all P>0.05).CONCLUSION: SLT can significantly reduce IOP in POAG patients in the short term, without damaging the visual field and optic disc nerves, while the effectiveness of SLT decreases over time.

Objective To analyze the current status of dietary quality in patients with chronic atrophic gastritis (CAG), and to explore the influencing factors of dietary quality. Methods A retrospective study was conducted on 550 patients with CAG admitted to the hospital from April 2021 to April 2024. Self-made basic data questionnaire, dietary balance index (DBI), and hospital anxiety and depression scale-anxiety subscale (HADS-A) were used for investigation. Multivariate linear regression analysis was applied to analyze the influencing factors of DBI-lower bound score (LBS). Results The average score of DBI-LBS in 550 patients with CAG was (31.45±8.53) points. There were significant differences in DBI-LBS scores among CAG patients in terms of age, body mass index (BMI), Helicobacter pylori (HP) infection, marital status, drinking history, smoking history, CAG severity, HADS-A score and concurrent gastrointestinal diseases (P<0.05). Multivariate linear regression analysis of the above influencing factors indicated that BMI, smoking history, HADS-A score and CAG severity were independent influencing factors of DBI-LBS score in CAG patients (P<0.05). Conclusion The general dietary quality is not optimistic in CAG patients, showing a moderate deficiency in dietary intake. BMI, disease severity and psychological status of patients are independent factors affecting dietary quality.

Objective:To investigate the differences in protein profile expression in serum samples from children with corona virus disease 2019（COVID-19）related encephalopathy and to explore the underlying mechanisms.Methods:From December 1,2022 to January 31,2023,28 children with COVID-19 who were admitted to the Department of Pediatric Intensive Medicine at Shandong Provincial Hospital Affiliated to Shandong First Medical University were collected,including 21 patients with encephalopathy(COVID-19 with encephalopathy group) and seven patients without encephalopathy(COVID-19 without encephalopathy group).Three children from each group were selected for serum proteomic analysis using tandem mass spectrometry labeling proteomics technology.Proteins were considered significantly different if the fold change was >1.2 or <0.8，with P<0.05.Bioinformatics analysis，including Gene Ontology and Kyoto Encyclopedia of Genes and Genomes Pathway Enrichment were performed on differentially expressed proteins.Protein-protein interaction networks were analyzed using the STRING database.Selected proteins were further validated by enzyme-linked immunosorbert assay. Results:A total of 41 differentially expressed proteins were identified between the two groups.Among these，14 proteins were upregulated and 27 proteins were downregulated in COVID-19 patients with encephalopathy compared to those without encephalopathy.Bioinformatics analysis revealed that these proteins were primarily enriched in critical signaling pathways，including complement and coagulation regulation，neutrophil degranulation and activation，and platelet degranulation.Enzyme-linked immunosorbert assay validation confirmed significant differences in key coagulation-regulating proteins(von willebrand factor upregulated，serpin family F member 2 downregulated in COVID-19 patients with encephalopatly）between the two groups.Conclusion:Coagulation dysfunction may play a role in the development of COVID-19 associated encephalopathy in children，providing valuable insights for future research.

Insufficient alveolar bone thickness increases the risk of periodontal dehiscence and fenestration, especially in orthodontic tooth movement. Abaloparatide (ABL), a synthetic analog of human PTHrP (1-34) and a clinical medication for treating osteoporosis, has recently demonstrated its potential in enhancing craniofacial bone formation. Herein, we show that intraoral submucosal injection of ABL, when combined with mechanical force, promotes in situ alveolar bone thickening. The newly formed bone is primarily located outside the original compact bone, implying its origin from the periosteum. RNA sequencing of the alveolar bone tissue revealed that the focal adhesion (FA) pathway potentially mediates this bioprocess. Local injection of ABL alone enhances cell proliferation, collagen synthesis, and phosphorylation of focal adhesion kinase (FAK) in the alveolar periosteum; when ABL is combined with mechanical force, the FAK expression is upregulated, in line with the accomplishment of the ossification. In vitro, ABL enhances proliferation, migration, and FAK phosphorylation in periosteal stem cells. Furthermore, the pro-osteogenic effects of ABL on alveolar bone are entirely blocked when FAK activity is inhibited by a specific inhibitor. In summary, abaloparatide combined with mechanical force promotes alveolar bone formation via FAK-mediated periosteal osteogenesis. Thus, we have introduced a promising therapeutic approach for drug-induced in situ alveolar bone augmentation, which may prevent or repair the detrimental periodontal dehiscence, holding significant potential in dentistry.

Objective:To analyze inpatients preferences for an unaccompanied ward and its influencing factors, for references for the implementation of unaccompanied ward management.Methods:Based on a convergent mixed research design, a convenience sampling method was used to select inpatients who visited a tertiary hospital from June to August 2024 as the survey subjects. A questionnaire survey was conducted on their willingness to choose the unaccompanied ward (provided by medical nursing staff). Meanwhile, using purposive sampling method, 10 inpatients and 11 accompanying family members were selected for semi-structured interviews about unaccompanied ward prference, and the interview topics were summarized and extracted. The results of quantitative and qualitative were compared and integrated.Results:The quantitative research results showed that among the 805 inpatients included, 125 patients (13.03%) chose medical caregivers, 382 patients (39.83%) chose their spouses, and 272 patients (28.36%) chose their children; 411 patients (24.54%) did not choose medical caregivers due to financial burden; 509 patients (63.23%) believed that the cost of an unaccompanied ward should be less than 120 yuan/day. The qualitative research results showed that the interview data formed three themes, including the driving factors of caregiving form selection intention, the emotional tendency of caregiving form selection intention, and the assessment of the benefits and drawbacks of caregiving form selection intention. The mixed research results showed that the majority of inpatients choose their spouse or children accompany them, and their willingness to choose medical caregivers is mainly influenced by service costs and family labor. However, its did not affect patients who are young or have difficulty caring for them; Influenced by traditional Chinese culture, patients tended to choose relatives to accompany them; The main reasons why patients did not choose unaccompanied wards were the economic burden and the mismatch between medical nursing staff services and their expectations.Conclusions:Inpatients tended to choose family members to accompany them. Their willingness to choose unaccompanied ward was influenced by economic burden, family labor, patient age, caregiving difficulty, and filial piety culture.

Objective:To evaluate the clinical process of fragment reattachment in crown-root fractures (CRF) of teeth that the fracture occurred between sub-gingival and supra-alveolar ridge (sub-gingival & supra-alveolar ridge) in the esthetic zone, and to analyze the feasibility of this minimally invasive technique for sub-gingival & supra-alveolar ridge CRF involving anterior teeth.Methods:Fourteen sub-gingival & supra-alveolar ridge CRF involving anterior teeth in 12 patients received fragment reattachment in the Department of Prosthodontics, School of Stomatology, the Fourth Military Medical University from January 2016 to August 2024. The success rate of the fractured teeth 3 years after reattachment and the complications during the follow-up period were retrospectively analyzed. The 3-year success rate and complications during follow-up were evaluated to assess the clinical efficacy of this technique.Results:The 14 treated teeth were followed for an average of (36.0±33.7) months (range: 4-99 months). Complications occurred in 2 teeth: one was extracted due to debonding and replaced with a removable partial denture, while the other developed a palatal sinus post-reattachment, which healed after local saline irrigation and medication (followed for 12 months without recurrence). The remaining 12 teeth exhibited no complications, resulting in a success rate of 13/14.Conclusions:Fragment reattachment is a minimally invasive, rapid, and cost-effective treatment option for sub-gingival & supra-alveolar ridge CRF in the anterior esthetic zone. With strict case selection, it delivers favorable outcomes and extends the clinical lifespan of affected teeth.

Objective:To evaluate the impact of roxadustat on thyroid function and to identify the associated factors in patients undergoing maintenance peritoneal dialysis (PD).Methods:This study was a single-center retrospective study. PD patients who received roxadustat or recombinant human erythropoietin (rHuEPO) treatment at Nanjing Drum Tower Hospital between January 2020 and June 2024 were included. The general and clinical information as well as laboratory indexes were collected. Serum free triiodothyronine (FT3), free thyroxine (FT4) and thyroid-stimulating hormone (TSH) were compared before and after treatment initiation. Hemoglobin (Hb) responses were also observed between the two groups. Logistic regression analysis was performed to explore the factors associated with thyroid function changes.Results:A total of 120 patients were enrolled, with an age of (55.17±16.42) years, including 66 males (55.0%). There were 81 patients received roxadustat (roxadustat group) and 39 patiens received rHuEPO (rHuEPO group). Compared to the rHuEPO group, the roxadustat group had a higher proportion of patients with diabetes ( χ 2= 4.172, P=0.041), a shorter PD vintage ( Z=-3.406, P=0.002), a lower serum level of total cholesterol ( Z=-2.082, P=0.037) and a lower level of fasting blood glucose ( Z=-2.589, P=0.010). Following treatment with roxadustat, the levels of FT4 ( Z=-5.349, P<0.01) and TSH ( Z=-3.720, P<0.01) decreased significantly. In contrast, no significant changes in FT4 or TSH levels were observed in the rHuEPO group (both P>0.05). For both roxadustat and rHuEPO groups, there were no significant changes in FT3 levels after treatment (both P>0.05). Multivariate analysis identified that higher baseline TSH (TSH≥2.27 μIU/ml, OR=1.581, 95% CI 1.196-2.089, P=0.001) and roxadustat exposure ( OR=3.432, 95% CI 1.410-8.355, P=0.007) as independent associated factors of subsequent TSH decline, and identified that higher baseline FT4 (FT4≥14.9 pmol/L, OR=1.390, 95% CI 1.162-1.662, P=0.001) and roxadustat exposure ( OR=5.798, 95% CI 2.225-15.113, P=0.001) as independent associated factors of subsequent FT4 decline. The degrees of hemoglobin changes after roxadustat or rHuEPO treatment did not differ significantly between roxadustat group and rHuEPO group ( t=-1.062, P=0.290). Of the 31 patients who underwent a second thyroid function test during roxadustat treatment, 24 continued with the original regimen, while 7 discontinued roxadustat. Among 24 patients who maintained roxadustat treatment, TSH ( Z=-0.400, P=0.689) and FT4 ( t=0.143, P=0.888) remained stable between the second and third tests. All 7 patients who discontinued roxadustat treatment showed TSH rebound and the changes of TSH levels were more significant than that in continuers ( Z=-2.505, P=0.012). FT4 recovery occurred in only 3 of them, with no significant difference in FT4 change between discontinuers and continuers ( Z=-0.685, P=0.493). Conclusions:Roxadustat commonly suppresses TSH and FT4, but not FT3, in PD patients. Baseline levels of TSH and FT4 are key associated factors of the inhibitory effect of roxadustat on thyroid function. This suppression does not intensify with prolonged exposure and is reversible after discontinuation, with TSH levels normalizing more quickly than FT4. Roxadustat-induced thyroid suppression does not compromise its efficacy in treating renal anemia.

Objective To investigate the protective effect and mechanism of tanshinone ⅡA on D-galactosamine(D-GalN)-induced acute liver failure in rats.Methods SD rats were randomly di-vided into control group,model group(intraperitoneal injection of 1.1 g/kg D-GalN),low-dose group(intraperitoneal injection of 1.1 g/kg D-GalN+daily gavage of 25 mg/kg tanshinone ⅡA),and High-dose group(intraperitoneal injection of 1.1 g/kg D-GalN+daily gavage of 50 mg/kg tan-shinone ⅡA).Liver function indicators[aspartate aminotransferase(AST),alanine aminotransferase(ALT),and γ-glutamyltransferase(γ-GT)]were measured using a Hitachi7600-210 biochemical an-alyzer,and serum total bilirubin(TBIL)and direct bilirubin(DBIL)levels were determined.The mitotic index(MI)and proliferating cell nuclear antigen(PCNA)positivity in liver tissues were examined.Enzyme-linked immunosorbent assay(ELISA)was used to detect plasma levels of tumor necrosis factor(TNF-α),interleukin(IL)-1β,IL-10,and IL-6 in rats from each group.Kits were employed to measure superoxide dismutase(SOD),glutathione(GSH),and malondialdehyde(MDA)contents in liver tissues of rats from each group.The TUNEL method was adopted to detect hepatocyte apoptosis rates in liver tissues,and immunoblotting was used to assess the expression of phosphorylated extracellular signal-regulated kinase 1/2(p-ERK1/2)and extracellular signal-regu-lated kinase 1/2(ERK1/2)proteins in liver tissues.Results Compared with the control group,the model group exhibited increased p-ERK1/2 protein expression(P＜0.05).Compared with the model group,both the low-dose and high-dose groups showed decreased p-ERK1/2 protein expres-sion(P＜0.05).The model group had an increased hepatocyte apoptosis index compared with the control group(P＜0.05).Both the low-dose and high-dose groups demonstrated decreased hepato-cyte apoptosis indices compared with the model group(P＜0.05).Compared with the control group,the model group had increased MDA levels and decreased SOD and GSH levels(P＜0.05).Both the low-dose and high-dose groups exhibited decreased MDA levels and increased SOD and GSH levels compared with the model group(P＜0.05).The model group showed increased levels of TNF-α,IL-1β,IL-10,and IL-6 compared with the control group(P＜0.05).Both the low-dose and high-dose groups had decreased levels of TNF-α,IL-1 β,IL-10,and IL-6 compared with the model group(P＜0.05).Compared with the control group,the model group had decreased MI and PCNA positivity rates(P＜0.05).Both the low-dose and high-dose groups exhibited increased MI and PCNA positivity rates compared with the model group(P＜0.05).The model group had in-creased AST,ALT,γ-GT,TBIL and DBIL values compared with the control group(P＜0.05).Both the low-dose and high-dose groups showed decreased AST,ALT,γ-GT,TBIL and DBIL val-ues compared with the model group(P＜0.05).Conclusion Tanshinone ⅡA may alleviate D-GalN-induced acute liver failure in rats through the ERK1/2 signaling pathway.
