AIM: To evaluate whether Wnt pathway-related genes previously implicated in high myopia(HM)could serve as candidate genes for HM in the Chinese Han population, and to identify risk loci associated with HM susceptibility.METHODS: A case-control association analysis was conducted, involving 530 HM patients(HM group)and 1 087 healthy controls. The test efficacy was estimated using Quanto software. Peripheral blood DNA was extracted using the magnetic bead method, and seven candidate single nucleotide polymorphisms(SNPs)were genotyped using the Sequenom MassARRAY system, including HIVEP3 rs17365632, rs35134694, rs11210537, CTNNB1 rs13072632, CAMK2N1 rs10753502, TCF4 rs41396445 and Wnt7B rs73175083. Differences in allele and genotype frequencies between the HM and healthy control groups were compared under different inheritance models. Haplotype analysis was performed using SHEsis plus.RESULTS: All 7 SNPs had a genotyping detection rate exceeding 90%, and were in Hardy-Weinberg equilibrium(P>0.05). The test efficacy of the sample size was above 90.13%, indicating that the samples were representative of the population. In the HM group, the A allele frequency of HIVEP3 rs11210537 was significantly reduced(Pc=0.003, OR=0.889). Conversely, the G allele frequency was significantly elevated(Pc=0.003, OR=1.176). In an additive genetic model(AA vs GG), the AA genotype frequency was significantly lower than the GG genotype frequency(Pc=0.003, OR=0.583). Additionally, the frequency of the CCA haplotype of rs17365632, rs35134694, and rs11210537 in HIVEP3 was decreased in the HM group compared to the control group(Pc=0.008, OR=0.791).CONCLUSION: The SNP locus rs11210537 in the HIVEP3 gene is associated with genetic susceptibility to HM in the Chinese Han population, with the G allele identified as risk genetic markers. The CCA haplotype of rs17365632, rs35134694, and rs11210537 in the HIVEP3 gene represents a protection haplotype for HM.

OBJECTIVE To enhance the training quality of anticoagulation specialty clinical pharmacists， address the resource limitations of a single training base， and promote homogenization of training quality. METHODS A multi-base joint training system for anticoagulation specialty clinical pharmacists in the Beijing area was established. A mixed research method was employed， collecting data through performance comparisons， questionnaires， and qualitative interviews to compare the differences between the joint training model （experimental group， n＝16） and traditional teaching model （the control group， n＝17）. RESULTS The established joint training system encompassed a unified joint training teaching plan， the formation of a joint training teaching team， the establishment of joint theoretical teaching courses， the implementation of joint case discussions and literature presentations， as well as strengthening the assessment throughout the joint training process. Compared to the control group [theoretical assessment of （76.44±3.66） points， case assessment of （84.31±3.27） points]， the experimental group students achieved higher scores in theoretical assessment （[ 79.85±4.64） points] and case assessment （[ 88.70±5.51） points] （P＜0.05）. Through questionnaires and qualitative interviews， the trainees in experimental group were highly satisfied with the joint training model in terms of theoretical learning， communication skills， and teaching interaction. CONCLUSIONS The multi-base collaborative training system for anticoagulation specialty clinical pharmacists can integrate advantageous resources and significantly enhance the training effectiveness of anticoagulation specialty clinical pharmacists， offering value for wider promotion.

BackgroundNon-suicidal self-injury （NSSI） behaviors are common among adolescents with depressive disorders， and school bullying is recognized as a major risk factor. Previous research has shown that self-esteem and alexithymia are closely associated with both school bullying and NSSI. However， the mediating roles of self-esteem and alexithymia in the link between school bullying and NSSI are unclear. ObjectiveTo explore the mediating roles of alexithymia and self-esteem in the relationship between school bullying and NSSI behaviors in adolescents with depressive disorders， in order to inform intervention strategies targeting NSSI in this population. MethodsA total of 335 adolescents diagnosed with depressive disorders and treated at the First Psychiatric Hospital of Harbin from July 2023 to October 2024 were enrolled. Assessments included a self-developed demographic questionnaire， Adolescent Non-suicidal Self-injury Assessment Questionnaire-Behavior （ANSAQ-B）， Delaware Bullying Victimization Scale-Student （DBVS-S）， Rosenberg Self-Esteem Scale （RSES）， and 26-item Toronto Alexithymia Scale （TAS-26）. Pearson correlation analysis was used to examine the relationship among variables. Controlling for gender and age at onset of depressive symptoms， mediation analysis was performed using the “mediation” package in R 4.4.2. ResultsScores on DBVS-S and TAS-26 were positively correlated with ANSAQ-B score （r=0.408， 0.417， P<0.01）， while RSES scores were negatively correlated（r=-0.300， P<0.01）. Regression analysis showed that school bullying and alexithymia significantly positively predicted NSSI behaviors （B=0.212， 0.333， P<0.01）， while self-esteem negatively predicted NSSI behaviors （B=-0.368， P<0.01）. Alexithymia was found to mediate the relationship between school bullying and NSSI behaviors， with an indirect effect of 0.040 （95% CI： 0.018~0.069） ，account for 17.17% of the total effect. The indirect effect through self-esteem was not statistically significant （95% CI： -0.004~0.069）. ConclusionExposure to school bullying and high levels of alexithymia are important predictors of NSSI behavior in adolescents with depressive disorders， and school bullying may indirectly influence NSSI behavior through alexithymia. ［Funded by Scientific Research Project of Health Commition of Heilongjiang Province，（number， 20230303090154］

OBJECTIVE To investigate the development and current status of medication education in domestic medical institutions， aiming to provide reference and suggestions for better development of medication education. METHODS The online questionnaire survey was conducted in March 2023 to investigate the implementation of medication education in medical institutions at all levels nationwide； descriptive analysis and influencing factors analysis were conducted. RESULTS A total of 1 368 questionnaires were recycled， 1 304 of which were effective questionnaires， with the effective rate of 95.32%. The average rate of providing medication education was 73.62% in medical institutions nationwide， 76.05%， 67.68% and 73.76% respectively in Eastern， Central and Western regions， 87.11%， 60.57% and 46.32% respectively in tertiary， secondary and primary medical institutions. The commonest place and way of carrying out medication education were dispensing window and oral instructions， and both were more diverse in tertiary medical institutions， compared with second and primary medical institutions. The median annual service volume of medication education in medical institutions PUMCH-A- at all levels was 500 people； the higher the level of medical institutions， the larger the annual service volume of medication education （P＝0.023）. More than half of medical institutions didn’t have any form of compensation for medication education， which was mostly reflected in the workload of medical institutions with compensation. Grade of medical institutions， degree of information and automation were the major influencing factors of carrying out medication education. CONCLUSIONS The ratio of carrying out medication education is improved in the central region in China in recent years， compared with 2019； while that of primary institutions in all regions is at a low level and should be improved. The place of carrying out medication education should be set according to the characteristics of medical institutions， and medication education forms should be enriched as much as possible. The quantity and quality of medication education talents still need to be improved. Compensation for pharmaceutical care should be continually explored and implemented to prompt high-quality and sustainable development of medication education.

Objective:To introduce a surgical technique of " short distances and multi-segment" buried-guiding suture method and its effects in the surgery of early descent of prosthesis after augmentation mammaplasty.Methods:From August 2019 to January 2022, 15 cases of early descent of prosthesis after augmentation mammaplasty due to axillary approach breast augmentation for micromastia were admitted to the Plastic Surgery Department of Sichuan Provincial People′s Hospital, aged 23-35 years (27.3±3.6) and duration of dislocation from 16 to 35 days (23.8±5.8). There were 12 patients showed unilateral prosthesis drops and 3 patients showed bilateral prosthesis drops. " Short distances and multi-segment" buried-guiding suture method was used to solve the problem, i. e., 2-0 non-absorbable sutures were used to eliminate the lower pole of prosthetic cavity with " short distances and multi-segment" sutures. The distance from the nipple to the midline of the sternum, the distance from the sternotomy to the nipple, the distance from the nipple to the inframammary fold and the distance from the midclavicular point to the inframammary fold were measured bilaterally before and after surgery, and statistical analysis was performed to evaluate the efficacy of the " short distances and multi-segment" buried-guiding suture method for early descent of prosthesis after breast augmentation.Results:All incisions healed by first intention without complications such as hematoma, infection, or scar hyperplasia. 15 patients were followed up for 6-12 months (8.0±1.9). 14 patients were satisfied with the results after surgery, and 1 patient received satisfactory results after secondary surgery. The distance from nipple to inframammary fold was shortened by 0.8-1.4 cm after surgery (1.2±0.2), and the distance from mid-clavicle to inframammary fold was shortened by 1.0-1.6 cm (1.3±0.4), and the differences were statistically significant as compared with the values before surgery ( t=31.17, P<0.05; t=33.78, P<0.05). After surgery, the change in the distance from nipple to sternal was 0.1-0.3 cm (0.16±0.10), and the change in the distance from sternal notch to nipple was 0-0.2 cm (0.12±0.10), and the differences were not statistically significant ( P>0.05). Conclusions:With the advantages of simple operation, little trauma and no additional incision, the " short distance and multi-stage" buried-guiding suture method in the surgery of early descent of prosthesis after augmentation mammaplasty is worthy of clinical application.

In order to address issues such as the decline in diagnostic performance of deep learning models due to imbalanced data distribution in psoriasis vulgaris,a VGG13-based deep convolutional neural network model is proposed by integrating the processing capability of the improved fuzzy KMeans clustering algorithm for highly clustered complex data and the predictive capability of VGG13 deep convolutional neural network model.The model is applied to the diagnosis of psoriasis vulgaris,and the experimental results indicate that compared with VGG13 and resNet18,the proposed approach based on deep learning and improved fuzzy KMeans is more suitable for identifying psoriasis features.

Objective To investigate the current status of mini-CEX scores among students in the Elderly Service Man-agement program after completing the"Fundamentals of Nursing"course and analyze the influencing factors.Methods A total of 99 students from the Elderly Service Management program at the Wuming campus of Guangxi Medical University were selected as the study subjects.Assessment tools included a general information questionnaire,the Chinese version of the Mini Clinical E-valuation Exercise(mini-CEX),the Self-Rating Scale of Self-Directed Learning(SRSSDL),and a self-learning ability assess-ment scale.Stepwise linear regression analysis was employed to explore the factors affecting mini-CEX scores.Results The total mini-CEX score for the 99 students was 49.00(44.00,55.00).Stepwise linear regression analysis revealed that being a student leader,SRSSDL scores,self-learning ability,and teaching model were significant factors(P＜0.05),explaining 56.8％of the total variance.Conclusion The clinical comprehensive ability of students in the Elderly Service Management program requires enhancement,influenced by multiple factors including teaching model,self-learning ability,and self-directed learning capacity.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

hippocampus and HT22 cells of hypoxia pre-acclimated(HPC)mice and their relationship with neuroprotection.Methods(1)Thirty-six male Institute of Cancer Research(ICR)mice were randomly divided into three groups according to the random number table method of complete randomization:the control group,the hypoxia group and the hypoxia preconditioning group,with 12mice in each group.Mice in the control group were not exposed to hypoxia,mice in the hypoxia group were exposed to hypoxia once,and mice in the hypoxia preconditioning group were exposed to hypoxia four times.Immediately after the end of hypoxia treatment,all mice were decapitated and killed and hippocampal tissues were isolated and preserved in groups.(2)HT22 cells were cultured in medium containing 10％foetal bovine serum and 100 U/ml penicillin-streptomycin.When cell confluence was greater than 90％,they were transferred to 24-well plates for culture and then processed in 2 batches.6 pmol disordered small interfering RNA(siRNA),MALAT1 siRNA(siMALAT1),NEAT1 siRNA(siNEAT1),siMALAT1+siNEAT1 were transfected into the negative control group,siMALAT1 group,siNEAT1 group,and siMALAT1+siNEAT1 group of the first batch of HT22 cells one by one by transfection reagent,and the blank group did not have any treatment;then they were cultured under normal conditions(5％CO2 and 95％air)for 48 h.In the second batch of HT22 cells,6 pmol of disordered siRNA,disordered siRNA,siMALAT1,siMALAT1,siNEAT1 and siNEAT1 were transfected one by one correspondingly to the negative control group and the negative control+oxygen-glucose deprived/reoxygen(OGD/R)group,siMALAT1 group,siMALAT1+OGD/R,siNEAT1 group,siNEAT1+OGD/R group.48 h after transfection,HT22 cells of negative control group,siMALAT1 group and siNEAT1 group were cultured under normal conditions(5％CO2 and 95％air),and the cells of negative control+OGD/R group,siMALAT1+OGD/R group and siNEAT1+OGD/R group were treated with OGD/R.That is,under low oxygen conditions(1％O2+5％CO2+94％N2)exposure for 8 h,and then culture under normal conditions for 16 h.(3)The real-time fluorescence quantitative polymerase chain reaction(PCR)and Western blot was

mRNA and NR2B protein after transfection of HT22 cells in each group,and the relative expression levels of haemoglobin breakdown products and activated cysteine protease protein 3 after transfection and OGD/R of HT22 cells in each group.The survival rate of HT22 cells in each group was calculated.Results(1)The differences in relative expression of MALAT1(F=43.92),NEAT1(F=506.4),NR2B mRNA(F=50.64)and NR2B protein(F=41.24)in the hippocampus of mice in the three groups were statistically significant(all P＜0.05).The relative expression of MALAT1([1.68±0.06]vs.[1.00±0.08]),NR2B mRNA([1.26±0.06]vs.[1.00±0.01]),and NR2B protein([1.47±0.05]vs.[1.00±0.01])was increased in the hypoxia group as compared to the control group(all P＜0.05),whereas the relative expression of NEAT1([1.02±0.10]vs.[1.00±0.03])were not statistically significant(P＞0.05),and the relative expression of MALAT1([1.12±0.13]vs.[1.00±0.08])and NEAT1([2.88±0.10]vs.[1.00±0.03])were increased in hypoxic preconditioned group.Compared with hypoxia group,the relative expression of NR2B mRNA([0.54±0.07]vs.[1.26±0.06])and NR2B protein([1.17±0.07]vs.[1.47±0.05])were decreased(both P＜0.05).(2)The differences in the relative expression of NR2B mRNA(F=36.92)and NR2B protein(F=56.98)after transfection of HT22 cells in the five groups were statistically significant(both P＜0.05).Compared with the negative control group,siMALAT1 group(NR2B mRNA:[2.04±0.08]vs.[0.94±0.04],NR2B protein:[1.72±0.13]vs.[0.93±0.02]),siNEAT1 group(NR2B mRNA:[2.15±0.13]vs.[0.94±0.04],NR2B protein:[1.87±0.46]vs.[0.93±0.02]),siMALAT1+siNEAT1 group(NR2BmRNA:[2.09±0.16]vs.[0.94±0.04],NR2B protein:[2.07±0.30]vs.[0.93±0.02])showed the relative NR2B mRNA and NR2B protein expression were increased(all P＜0.05).(3)Differences in relative expression of haematopoietin breakdown product(145/150 kDa)protein(F=12.43),haematopoietin breakdown product(120 kDa)protein(F=7.15),and activated cysteamine protease protein 3 protein(F=6.61)were statistically significant in the 6 groups of HT22 cells transfected and treated with OGD/R(all P＜0.05).Compared with the siMALAT1 group,the siMALAT1+OGD/R group had 145/150kDa([1.42±0.48]vs.[0.85±0.34]),120 kDa([1.33±0.37]vs.[0.52±0.19])haematopoietin catabolism products and activated cysteamine protease protein 3([2.43±0.35]vs.[1.15±0.24])relative expression increased(all P＜0.05);compared with the negative control+OGD/R group,the siMALAT1+OGD/R group showed an increase in

3([2.43±0.35]vs.[1.46±0.39])increased(all P＜0.05);compared with the siNEAT1 group,the siNEAT1+OGD/R group had a higher expression of 145/150 kDa([1.28±0.44]vs.[0.87±0.32]),120 kDa([0.81±0.36]vs.[0.63±0.16])relative expression of haematopoietic proteolytic products and activated cysteamine protease protein 3([1.51±0.45]vs.[1.01±0.27])increased(all P＜0.05).(4)The difference in HT22 cell survival rate among the 6 groups was statistically significant(F=5.54,P＜0.05).Compared with the negative control group,HT22 cell survival was decreased in the siMALAT1,siNEAT1,siMALAT1+OGD/R and siNEAT1+OGD/R groups([0.65±0.40],[0.76±0.35],[0.24±0.17],[0.23±0.16]vs.[0.84±0.04],all P＜0.05);cell viability was reduced in the siMALAT1+OGD/R group compared with the siMALAT1 group([0.24±0.17]vs.[0.65±0.40],P＜0.05);and cell viability was reduced in the siNEAT1+OGD/R group compared with the siNEAT1 group([0.23±0.16]vs.[0.76±0.35],P＜0.05).Conclusion HPC increased the expression of MALAT1 and NEAT1 in the hippocampus of mice,and MALAT1 and NEAT1 may participate in the neuroprotective effect of mice after ischemia and hypoxia by affecting the expression of NR2B.
