Objective To explore the correlation between osteocalcin (OCN) and visceral fat area (VFA) in overweight/obese population. Methods The data of 297 overweight/obese people who underwent health examinations in Health Management Department of Second Affiliated Hospital of Xi'an Jiaotong University from August 2021 to August 2024 were analyzed. According to the VFA value measured by InBody, the subjects were divided into an excessive group (VFA ≥100 cm²) and a normal group (VFA<100 cm2). The baseline data, glucose metabolism indicators, lipid metabolism indicators and OCN were compared between the two groups. Binary logistic regression analysis was used to analyze the independent risk factors affecting visceral fat deposition in overweight/obese people. Results According to the VFA value, there were 193 cases (64.98%) in the excessive group and 104 cases (35.02%) in the normal group. There were no statistical differences in gender, age and comorbidities between the two groups (P>0.05). The BMI, FPG, HbA1c, TC, TG, and LDL-C in the excessive group were higher than those in the normal group, while the HDL-C and OCN were lower than those in the normal group (P<0.05). Binary logistic regression analysis revealed that BMI, FPG, HbA1c, TC, TG and LDL-C were independent risk factors for visceral fat deposition in overweight/obese people, while HDL-C and OCN were protective factors (P<0.05). Conclusion Visceral fat deposition in overweight/obese people is closely related to OCN content, and is affected by abnormal glucolipid metabolism, which provides new ideas for the prevention and treatment of obesity-related diseases.

To summarise the clinical experience of Professor CHAO Enxiang in treating idiopathic pulmonary hemosiderosis （IPH） by staging from heat， phlegm， stasis and deficiency. It is believed that IPH has blood-heat and phlegm-stasis， and deficiency of qi and yin as the core pathomechanisms， in which the pathomechanism of acute pulmonary haemorrhage is based on intense blood heat， and modified Shihui Powder （十灰散） is used to clear heat and regulate ying qi （nutrient qi）， and reduce fire to settle the collaterals. The pathomechanism of pulmonary haemorrhage in the static stage is based on phlegm-heat obstructing the lungs， and modified Qingfei Dingke Decoction （清肺定咳汤） is used to clear the lungs and dissolve phlegm， harmonize the collaterals to stop haemorrhage. The pathomechanism of acute exacerbation at chronic stage is based on deficiency of qi and yin， and also blood-heat and phlegm-stasis， modified Shengmai Powder （生脉散）， Shihui Powder plus Qingfei Dingke Decoction should be used to benefit qi and nourish yin， clear heat， resolve phlegm and eliminate blood stasis. In the chronic prolongation period， the pathogenesis of the disease is based on the deficiency of qi and yin， modified Shengmai Powder may be used to benefit qi and nourish yin， moisten the lungs and rest blood.

AIM: To compare the visual quality in patients with low-to-moderate myopia after 0.05 D interval spherical lens optometry-guided small-incision lenticule extraction(SMILE)and conventional 0.25 D interval spherical lens optometry-guided SMILE.METHODS: Retrospective study. A total of 400 cases(400 eyes)with low-to-moderate myopia that underwent SMILE in the ophthalmology department of 989th Hospital of Joint Logistic Support Force from August 2021 to August 2023 were enrolled and the data from the right eyes were collected for analysis. According to the method of optometry test modality, they were divided into 0.05 D group and 0.25 D group, with 200 eyes in each group. The differences were compared between the two groups of patients in intraoperative corneal ablation thickness, uncorrected distance visual acuity(UDVA), high-order corneal aberrations(HOA), spherical aberrations, vertical coma, horizontal coma and trefoil aberrations before and at 1, 3 and 6 mo after surgery. Additionally, the percentage of eyes with residual spherical equivalent(SE)≤±0.25 D, postoperative visual symptoms and scores on the quality of visual(Qov)were compared between the two groups at 6 mo after surgery.RESULTS: The corneal ablation thickness in the 0.05 D group was 92.78±16.56 μm, which was slightly higher than that in the 0.25 D group(83.24±17.33 μm; P<0.001). The UDVA at each postoperative time point in the 0.05 D group was superior to that in the 0.25 D group(all P<0.001). The HOA, spherical aberration, horizontal coma and vertical coma in the two groups at 1, 3 and 6 mo after operation were higher than those before operation(all P<0.05). The spherical aberration in the 0.05 D group at each time point after surgery were higher than those in the 0.25 D group, and vertical coma were lower than those in the 0.25 D group(all P<0.05). At 6 mo postoperatively, the percentage of eyes with residual SE ≤±0.25 D in the 0.05 D group was 97.5%(195 eyes), which was higher than 87.5%(175 eyes)in the 0.25 D group(P<0.05). The most common adverse visual symptoms after SMILE in both groups were hazy vision and glare. The total Qov score in the 0.05 D group was 0.35(0.24, 0.55), which was lower than [0.62(0.32, 0.89)] in the 0.25 D group(P<0.05).CONCLUSION: Compared with conventional 0.25 D interval spherical lens optometry-guided SMILE, the 0.05 D interval spherical lens optometry-guided SMILE for the correction of low-to-moderate myopia has better predictability and can achieve better vision and visual quality.

Objective: To investigate the hematological characteristics of the rare McLeod phenotype associated with X-linked chronic granulomatous disease, KEL and XK gene analysis, identification of unexpected antibodies, serological characteristics of high-frequency antigen antibodies, and transfusion strategies. Methods: Serological methods were employed to determine the ABO, Rh, and other blood group system antigen phenotypes of the child, along with screening and identification of unexpected antibodies. The titers of high-frequency antigen antibodies were measured using tube antihuman globulin and microcolumn gel card techniques. Kell blood group typing was performed using serological and genotyping methods, while XK gene sequencing was conducted via next-generation sequencing. Peripheral blood smears from the child's mother were examined for erythrocyte morphology. Results: The child's serological results were as follows: blood group O, ccDEE, MM, Le(a-b+), JK(a+b+), Fy(a+b-), and Kell phenotype K-k+, Kp(a-b+). Plasma analysis revealed alloantibodies anti-C、e, as well as a high-frequency antigen antibody anti-KL, with titers of 512 (tube method) and 2 048 (microcolumn gel method). Genotyping results showed KEL genotype K-k+, Kp(a-b+), Js(a-b+), while XK gene NGS identified a hemizygous deletion of exons 1-3 (XK N. 01), consistent with XK: -1 or Kx-(McLeod). The mother's peripheral blood smear exhibited prominent acanthocytes. Conclusion: The hematological features of this rare McLeod phenotype with X-CGD include weakened Kell antigen expression and a complete exon deletion in the XK gene. Early clinical attention should be given to the symptoms and laboratory diagnosis of X-linked chronic granulomatous disease in pediatric patients. XK genotyping for McLeod phenotype should be prioritized to guide cautious transfusion strategies, preventing life-threatening complications due to incompatible blood products.

ObjectiveTo analyze the epidemiological trends and characteristics of brucellosis in humans (hereinafter referred to as brucellosis) in Tangshan City, Hebei Province from 2016 to 2023, and to provide a scientific basis for formulating brucellosis prevention and control strategies in the region. MethodsThe incidence data of human brucellosis in Tangshan City from 2016 to 2023 were collected from the China Disease Prevention and Control Information System. The diagnosis time, infection route, and clinical characteristics of the cases were obtained from the case investigation reports. Descriptive epidemiological methods were used to analyze the temporal, spatial, demographic distributions, and clinical characteristics of human brucellosis. Brucella species were identified using agglutination tests with bacterial suspension and A/M antigen-positive serum. ResultsA total of 2 193 cases of human brucellosis were confirmed and clinically diagnosed in Tangshan City from 2016 to 2023, with the peak incidence occured from March to August, and which exhibited distinct geographic distribution patterns. The highest incidence rate was found in people aged 60‒<70 years. The occupation of cases were primarily farmers. The incidence rate in males (528/100 000) was higher than that in females (184/100 000). All cases had confirmed exposure to infected animals or contaminated animal products. ConclusionThe epidemic of human brucellosis in Tangshan exhibited an overall steady downward trend from 2016 to 2023, except for a slight increase in 2016 and 2021, with the incidence rate controlled at 289/100 000‒335/100 000. The prevention and control situation of human brucellosis still remains severe, with the highest incidence rate in the eastern region of Tangshan, which are characterized by the breeding, slaughtering, and processing of cattle and sheep. Therefore, it it is necessary to enhance the prevention and control of human brucellosis among the personnel engaged in these industries in the eastern areas.

Objective To explore the efficacy and safety of the Huoxue Tongluo recipe iontophoresis(HTRI)combined with butylphthalide sequential therapy(BST)in patients with cerebral ischemic stroke(CIS)hemiplegia.Methods 87 patients with CIS hemiplegia treated in Chuzhou Chinese and Western Medicine Hospital affiliated to Anhui University of Chinese Medicine from January 2020 to January 2023 were retrospectively selected as study subjects,and were divided into the BST group(BST treatment)and the combination group(BST in combination with HTRI treatment)according to the treatment regimens.The main observation indicators were total treatment response rate and incidence of adverse reactions after 4 weeks of treatment;the secondary observation indicators were cerebral artery flow velocity[anterior cerebral artery(ACA),middle cerebral artery(MCA)and posterior cerebral artery(PCA)],neurological function[National Institutes of Health Stroke Scale(NIHSS)score,Chinese Stroke Scale(CSS)score]and limb function[Fugl-Meyer Motor Function Scale(FMA)score,Barthel index(BI)score].Results A total of 87 patients were included,including 43 patients in the BST group and 44 patients in the combination group.The total response rate in the combination group was significantly higher than that in the BST group(P<0.05),and no adverse reactions were observed in both groups.Before treatment,there were no significant differences in cerebral artery blood flow velocity,nerve function and limb function between the two groups(P>0.05).After treatment,the flow velocity of ACA,PCA and MCA,and the scores of FMA and BI were significantly higher than those before treatment(P<0.05),while the scores of NIHSS and CSS decreased significantly(P<0.05).Conclusion Compared with BST therapy,HTRI combined with BST has a more significant effect in CIS patients with hemiplegia,with no increase in the incidence of adverse reactions,and has higher safety.

Objective:To explore the effect of problem-based learning (PBL) combined with case-based learning (CBL) in insulin injection patients with type 2 diabetes mellitus (T2DM) .Methods:From August to October 2022, convenience sampling was used to select 120 patients with T2DM treated with insulin injection from the Endocrinology Department of Yiwu Central Hospital as the study subject. According to the admission time, patients were divided into a control group and an intervention group, with 60 cases each. The 60 patients admitted from August 1st to 31st were in the control group and received routine health education, and 60 patients admitted from October 1st to 31st were included in the intervention group and received PBL combined with CBL. This study analyzed and compared the awareness rate of insulin injection knowledge and assessment scores of insulin injection between two groups of patients, and counted the passing rate and improvement rate of assessment scores after intervention. Before and after three months of intervention, this study evaluated the patient's blood glucose status [fasting blood glucose (FPG), 2-hour postprandial blood glucose (2hPG), and glycated hemoglobin (HbA1c) ], and counted the incidence of insulin injection related complications.Results:After four weeks of intervention, the overall awareness rate of insulin injection knowledge in the intervention group was higher than that in the control group, with a statistically significant difference ( P<0.05). The insulin injection assessment score (90.35±4.68), passing rate of assessment score 91.67%, and improvement rate of assessment score (35.48±6.84) % in the intervention group were higher than those [ (84.69±6.72), 75.00%, and (26.28±5.46) %] in the control group, and the differences were statistical ( P<0.05). After three months of intervention, the FPG, 2hPG, and HbA1c of the intervention group patients were lower than those of the control group, with statistically significant differences ( P<0.05). Within three months after intervention, the total incidence of complications in the intervention group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:PBL combined with CBL for insulin injection patients can help to increase their knowledge and operational level of insulin injection, improve blood glucose control, and reduce insulin injection related complications.

Objective:To investigate the potential mechanism of miR-1298-5p in non-small cell lung cancer(NSCLC)to regu-late the MSH2 gene and its effect on the biological behavior of tumor cells and the tumor immune microenvironment.Methods:Bioin-formatics was used to identify the key genes and miRNA involved in NSCLC.Cell proliferation was detected by CCK-8 assay,and cell invasion and migration were detected by Transwell assay.Levels of inflammatory factors were detected by ELISA assay.Western blot was used to measure the expression of MSH2 in cells,and fluorescence quantitative polymerase chain reaction(RT-qPCR)was used to detect the expressions of miR-1298-5p and MSH2 gene in NSCLC cells.Dual luciferase reporter gene assay was performed to verify the targeting relationship between miR-1298-5p and MSH2.Spearman correlation analysis was performed to correlate miR-1298-5p with immune cells and immune factors in the tumor immune microenvironment.Results:The level of miR-1298-5p was down-regulated in NSCLC cells compared with normal lung tissue cells.miR-1298-5p overexpression inhibited the proliferation,migration and inva-sion of NSCLC cells.MSH2 was confirmed to be a target gene of miR-1298-5p using luciferase reporter gene assay.Furthermore,down-regulation of miR-1298-5p in NSCLC cells could be reversed by silencing MSH2.miR-1298-5p expression levels were negatively corre-lated with the levels of Treg,IL-10,and TGF-β,and positively correlated with the levels of CD3+T,CD4+T,CD8+T,NK cells,IL-2,and IFN-γ.Conclusion:miR-1298-5p negatively regulates MSH2 to inhibit the proliferation,invasion and migration of NSCLC cells and improve the tumor immune microenvironment.
