OBJECTIVE: Therapeutic angiogenesis has become a promising approach for treating ischemic heart disease (IHD). The present study aims to investigate the effects of Qishen Granule (QSG) on angiogenesis in myocardial ischemia (MI) and the potential mechanism. METHODS: In vivo study was conducted on rat model of myocardial infarction. QSG was performed daily at a dose of 2.352 g/kg for four weeks. Cardiac function was assessed by echocardiogram and pro-angiogenic effects were evaluated by Laser Doppler and CD31 expression. Oxygen-glucose deprivation (OGD) was applied in cultured human umbilical vein endothelial cells (HUVECs). Cell viability, wound healing and tube formation assay were used to test functions of HUVECs. ELISA and Western blots were used to assess protein expressions of bone morphogenetic protein 2-delta-like 4-notch homolog 1 (BMP2-Dll4-Notch1) signaling pathway. RESULTS: The results showed that QSG improved heart function, cardiac blood flow and microvessel density in myocardial ischemic rats. In vitro, QSG protected HUVECs by promoting the cell viability and tube formation. QSG upregulated bone morphogenetic protein-2 (BMP2) and downregulated delta-like 4 (Dll4) and notch homolog 1 (Notch1) expressions both in rats and HUVECs. CONCLUSION QSG protected against MI by promoting angiogenesis through BMP2-Dll4-Notch1 pathway. BMP2 might be a promising therapeutic target for IHD.

Objective:To investigate the levels and clinical significances of miRNA-155-5p (miR-155-5p) and hypoxia inducible factor-1α (HIF-1α) in the bone marrow of patients with acute myeloid leukemia (AML)-M 5. Methods:A cross sectional study was conducted. The bone marrow samples were collected from 32 AML-M 5 patients who were admitted to the First Affiliated Hospital of Hebei North University from November 2023 to December 2024, and the bone marrow samples collected from 11 patients with megaloblastic anemia from November 2023 to May 2025 were used as controls. Reverse transcription real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to determine relative expression of miR-155-5p at the transcription level in bone marrow mononuclear cells, and enzyme-linked immunosorbent assay (ELISA) was used to measure the concentration of HIF-1α protein in bone marrow supernatant. The levels of miR-155-5p and HIF-1α in bone marrow were compared between AML patients and control group, as well as among AML patients with different prognostic risks. Spearman method was used to analyze the relationship between miR-155-5p level and HIF-1α level in bone marrow of AML patients and their levels with bone marrow and peripheral blood cell indicators. Results:Among the 32 AML-M 5 patients, 20 patients (62.5%) were male and 12 patients (37.5%) were female, with a median age [ M ( Q1, Q3)] of 63 (51, 70) years; according to the clinical response criteria recommended by the European Leukemia Network (ELN) in 2022, there were 12 cases (37.5%) of complete response (CR) and 8 cases (25.0%) of non-complete response (NCR); according to the risk stratification criteria recommended by ELN in 2022, there were 8 cases (25.0%) with good prognosis, 13 cases (40.6%) with moderate prognosis and 11 cases (34.4%) with poor prognosis. In the control group, there were 5 males and 6 females, with a median age of 68 (63, 72) years. There was no statistically significant difference in gender and age between the two groups (both P > 0.05). The transcription level relative expression of miR-155-5p in the bone marrow mononuclear cells of AML-M 5 patients [5.13 (2.83, 8.84) vs. 0.87 (0.56, 1.69)] and the concentration of HIF-1α protein in the bone marrow supernatant of AML-M 5 patients [(116±32) pg/ml vs. (58±22) pg/ml] were higher than those in the control group, and the differences were statistically significant (both P < 0.001). The relative expression of miR-155-5p at the transcription level in the initial diagnosis group and NCR group and the concentration of HIF-1α in the initial diagnosis group, NCR group and CR group were higher than those in the control group (all P < 0.01), the relative expression of miR-155-5p at the transcription level in the CR group was higher than that in the control group, but the difference was not statistically significant ( P > 0.05); the relative expression of miR-155-5p at the transcription level in the newly diagnosis group was higher than that in the CR group, and the difference was statistically significant ( P < 0.01). However, there was no statistically significant difference between the newly diagnosis group and the NCR group or between the NCR group and the CR group (all P > 0.05). The concentration of HIF-1α in the newly diagnosis group and NCR group was higher than that in the CR group, and the differences were statistically significant (both P < 0.05). However, there was no statistically significant difference between the newly diagnosis group and the NCR group ( P > 0.05). There was no statistically significant difference in the relative expression of miR-155-5p at the transcription level and HIF-1α concentration in bone marrow among AML-M 5 patients with poor prognosis, moderate prognosis and good prognosis (both P > 0.05). The level of miR-155-5p in the bone marrow of AML-M 5 patients was positively correlated with the level of HIF-1α ( r = 0.446, P = 0.010); the level of miR-155-5p in bone marrow was positively correlated with the proportion of bone marrow primitive cells ( r = 0.583, P < 0.001), peripheral blood leukocyte count ( r = 0.464, P = 0.008), peripheral blood monocyte count ( r = 0.464, P = 0.007), and peripheral blood monocyte-to-leukocyte ratio ( r = 0.457, P = 0.009). The concentration of HIF-1α in the bone marrow of AML-M 5 patients was positively correlated with the proportion of bone marrow primitive cells ( r = 0.568, P = 0.001) and peripheral blood mononuclear cells-to-white blood cells ratio ( r = 0.375, P = 0.034), but not with peripheral blood white blood cell count ( r = 0.159, P = 0.385) or peripheral blood mononuclear cell count ( r = 0.300, P = 0.095). Conclusions:The levels of miR-155-5p and HIF-1α in the bone marrow of AML-M 5 patients are relatively high, and the levels of both are lower in patients with remission. However, the levels of both may not be related to the risk of prognosis. The levels of miR-155-5p and HIF-1α in the bone marrow of AML-M 5 patients are positively correlated, and their levels are also positively correlated with major hematological indicators in the bone marrow and peripheral blood.

Objective:To explore and compare early postoperative clinical outcomes between dynamic and classical superior capsular reconstruction for the treatment of irreparable post-superior massive rotator cuff tears (MIRCTs).Methods:29 patients with MIRCTs treated with autologous fascia dynamic SCR (14) and classical SCR (15) at Department of Sports Medicine of the First Affiliated Hospital of Army Medical University from September 2019 to March 2022 were retrospectively analyzed on preoperative and final follow-up pain visual analogue scale (VAS), Constant-Murley score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) score, range of motion (ROM), acromiohumeral distance (AHD), Sugaya classification and Goutallier classification.Results:All 29 patients were followed up with an average follow-up time of 36.50±8.18 months for dynamized SCR and 29.33±9.15 months for classical SCR, respectively. There was no significant difference between the two groups in terms of gender, age, course of disease and preoperative AHD ( P>0.05). At the final follow-up, there was no significant difference in the degree of improvement in forward flexion (81.79°±36.14° vs. 69.00°±40.19°, t=0.899, P=0.377), abduction [87.50°(71.25°, 122.50°) vs. 80.00°(45.00°, 95.00°), Z=-1.400, P=0.172] and internal rotation [5.00°(5.00°, 6.00°) vs. 4.00°(1.00°, 6.00°), Z=-0.871, P=0.400]; external rotation improved significantly in the dynamic SCR group compared to classical SCR group [37.50°(30.00°, 41.25°) vs. 25.00°(15.00°, 30.00°), Z=-2.285, P=0.019]. Although both groups showed clinical improvements, no significant difference was found between the dynamic SCR group and the classical SCR group on VAS [4.00(3.75, 5.00) vs. 4.00(3.00, 5.00), Z=-0.029, P=0.949], ASES score (50.99±7.98 vs. 46.47±13.73, t=1.074, P=0.293), Constant-Murley score [62.50(54.00, 69.50) vs. 56.00(47.00, 62.00), Z=-1.956, P=0.112] and UCLA score (20.21±3.53 vs. 18.40±3.87, t=1.315, P=0.199). At the final follow-up, patients in the dynamic SCR group had a higher degree of improvement in AHD (3.66±2.22 mm vs. 2.00±1.75 mm, t=2.247, P=0.033). There was no significant difference in Sugaya grading between the two groups at the final follow-up ( Z=-0.370, P=0.747). As for the degree of improvement in Goutallier's grading, there was an improvement in the dynamic SCR group at the final follow-up versus the preoperative period ( Z=-2.101, P=0.036), while there was no significant difference in the degree of improvement in the classical SCR group at the final follow-up versus the preoperative period ( Z=-0.700, P>0.05). Conclusion:Both dynamic SCR and classical SCR for MIRCTs significantly improved shoulder function. Significant improvements in external rotation, AHD and Goutallier grading were observed in the dynamic SCR group compared to the classical SCR group.

【Objective】 To estimate the prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province so as to provide evidence for the prevention and control of non-communicable diseases. 【Methods】 We used the data of adults aged 18 years and older collected in the baseline survey of Shaanxi Project in the Regional Ethnic Cohort Study in Northwest China. Multinomial logistic regression was used to explore the associated factors for multimorbidity. Exploratory factor analysis was used to extract patterns of multimorbidity. 【Results】 The prevalence of multimorbidity was 10.7% among the 44 442 participants. Age increase, being males, urban residence, and being overweight or obesity were positively associated with multimorbidity. Compared with women, men had a higher risk of multimorbidity. The OR and 95% CI was 1.25 (1.12-1.39). The risk of multimorbidity increased with age among adults. Compared with participants aged 18.0-34.9 years, the ORs and 95% CIs of those aged 35.0-44.9, 45.0-54.9, 55.0-64.9, and ≥65.0 years were 4.73 (3.47-6.46), 15.61 (11.60-21.00), 41.39 (30.76-55.70) and 90.04 (66.58-121.77), respectively. The primary multimorbidity patterns among adults in Shaanxi were cardiovascular-metabolic multimorbidity (5.4%), viscero-articular multimorbidity (1.0%), and respiratory multimorbidity (0.3%). 【Conclusion】 More than one in ten adults in Shaanxi Province had multimorbidity, and the predominant pattern of multimorbidity was cardiovascular-metabolic multimorbidity. The prevention and control of non-communicable diseases should be reinforced in middle-aged and older people, males, people living in the urban, and overweight or obese people. More attention should be paid to the prevention and control of cardiovascular-metabolic diseases.

【Objective】 To evaluate the dietary quality with the dietary balance index (DBI_16) and the association between dietary quality and bone mass among middle-aged and elderly people in Gansu Province so as to provide evidence for improving dietary quality and bone health status of Gansu population. 【Methods】 Based on the information of the type and quantity of food intake and the bone mass of middle-aged and elderly people aged 35 years and above collected by the Gansu Project in the Regional Ethnic Cohort Study in Northwest China, DBI_16 was used to evaluate the intake level of cereals, vegetables, fruits, milk, beans, fish and shrimp, eggs and other foods, and the degree of inadequate, excessive and unbalanced dietary intake of the participants. Multiple linear regression was used to evaluate the associations of three component indexes of DBI_16, high bound score (DBI_HBS), low bound score (DBI_LBS), diet quality distance (DBI_DQD), and seven single indexes of DBI_16 with bone mass. 【Results】 Analyses of the dietary and bone mass data of 11,840 participants showed that 44.8% of participants consumed excessive amounts of cereals compared to the dietary recommendation. 96.3%, 90.6%, 90.1%, 71.9%, 95.1% and 60.3% of participants’ intake of vegetables, fruits, milk, soybeans, fish and shrimp, and eggs, respectively, were inadequate. 47.7% participants consumed less than 10 types of food. 2.3% participants’ DBI_LBS levels were appropriate. 54.7% participants’ DBI_HBS levels were appropriate. Only 1.2% participants’ DBI_DQD reached a balanced level. The bone mass level in the study population was (2.5±0.6) kg [(2.8±0.5) kg for men and (2.3±0.5) kg for women]. After adjusting for sociodemographic characteristics, lifestyle, total dietary energy intake and body mass index, DBI_LBS and DBI_DQD were negatively associated with bone mass [β and 95% CI was -0.002 01 (-0.003 62--0.000 40) and -0.001 76 (-0.003 09--0.000 43), respectively]. 【Conclusion】 Dietary intake imbalance is common among middle-aged and elderly people in Gansu Province, and the more severe the dietary intake imbalance, the lower the bone mass level.

Objective:To investigate the gut microbiota composition in subclinical hypothyroidism and euthyroidism patients with Hashimoto′s thyroiditis, and its relationship with clinical indicators and inflammatory factors.Methods:A total of 48 patients diagnosed with Hashimoto′s thyroiditis and 28 healthy controls(HC group) were enrolled from Henan Provincial People′s Hospital from July 2019 to March 2022 in this cross-sectional study. According to thyroid function, 18 patients with Hashimoto′s thyroiditis were divided into subclinical hypothyroidism group(SH group) and 30 patients in euthyroidism function group(Eu group). Fecal microbial composition was detected by 16S rRNA sequencing technology, and peripheral blood was collected to test clinical indicators and inflammatory factors.Results:Compared with HC group, there were significant differences in α and β diversity of gut microbiota in SH and Eu group( P=0.045, P=0.037). At the phylum level, Firmicutes, Bacteroidota, and Proteobacteria were the dominant phylum in the three groups. At the genus level, the abundance of 4 bacterial genera increased gradually in HC group, Eu group, and SH group, including Streptococcus, Comamonas, Elizabethkingia, Achromobacter. However, the abundance of the other 9 genera decreased gradually, such as Subdoligranulum, Coprococcus, Oscillospirales_ UCG-010, Clostridia_ UCG-014, Oscillospiraceae_ UCG-002, Alistipes et al. In addition, the level of serum B-cell activating factor was positively correlated with several bacterial genera such as Achromobacter, Streptococcus, Intestinibacter et al. Conclusion:There are differences in the gut microbiota structure of patients with Hashimoto′s thyroiditis in different thyroid functional states, which is correlated with inflammatory factors.

Objective:To investigate the clinical relationship between homocysteine (Hcy) metabolizing enzyme gene polymorphism and poor prognosis of multiple myeloma (MM) in Han nationality.Methods:One hundred and twenty-eight MM patients of Han nationality admitted to the First Affiliated Hospital of Hebei North University from February 2018 to March 2020 were selected as the disease group, and 120 healthy volunteers of Han nationality were recruited as the control group at the same time. Blood samples were taken to detect plasma Hcy level and Hcy metabolizing enzyme gene polymorphism, including methylenetetrahydrofolate reductase(MTHFR) C677T, MTHFRA1298C, methionine synthase reductase(MTRR) A66G, cystathionine beta-synthase(CBS) 844ins68 and methionine synthase (MS) A2756G. The patients in the disease group were treated with conventional methods , followed up for 1 year after treatment, and the incidence of poor prognosis was counted. Plasma Hcy level, genotype distribution and allele frequency of Hcy metabolic enzymes were compared between the two groups. Logistic multiple regression analysis was used to analyze the association of Hcy metabolizing enzyme gene polymorphism with MM poor prognosis in Han nationality.Results:The plasma Hcy level in the disease group was higher than that in the control group: (15.01 ± 2.98) μmol/L vs. (8.45 ± 1.69) μmol/L, there was statistical difference ( P<0.05). The frequency of TT genotype and T allele of MTHFRC677T locus in the disease group were higher than those in the control group : 26.56% vs. 6.67% , 29.30 vs. 16.25%; while the frequency of CT genotype in the disease group was lower than that in the control group: 5.47% vs. 19.17% , there were statistical differences ( P<0.05). There were no significant differences in genotype distribution and allele frequency of other gene loci between the two groups ( P>0.05). The incidence of poor prognosis in the disease group was 49.22%(63/128). Age, platelet count, serum β 2 microglobulin level, serum κ light chain level, plasma Hcy level and TT genotype of MTHFRC677T locus were the influencing factors of poor prognosis in the disease group ( OR = 7.286, 0.545, 6.841, 6.284, 8.117 and 8.440; P<0.05). Conclusions:The plasma Hcy level, TT genotype and T allele frequency of MTHFRC677T locus in MM patients of Han nationality are higher than those in healthy people, while the CT genotype frequency is lower than that in healthy people. The poor prognosis of MM in Han nationality is related to plasma Hcy level and TT genotype of MTHFRC 677T locus.

Objective:To investigate whether FcγRⅡb rs775 single nucleotide polymorphism confers susceptibility to Hashimoto′s thyroiditis and its impact on expression of FcγRⅡb protein on B cell surface.Methods:A total of 187 Hashimoto′s thyroiditis patients(HT group) were enrolled, including 46 males(24.60%) and 141 females(75.40%), with a median age of 43(32, 53) years, and 187 healthy controls(conrol group), including 62 males(33.16%) and 125 females(66.84%), with a median age of 41(31, 51) years. The peripheral blood of two groups were sequenced, genotype and allele frequencies distribution of FcγRⅡb rs775 T>C were compared with clinical parameters as strata between the two groups. At the same time, the expression of inhibitory receptor FcγRⅡb on B cell surface was detected using flow cytometry.Results:Compared with control group, the mutant homozygous CC genotype was obviously enrichment in HT group( OR=3.321, 95% CI 1.175-9.386, P=0.018), and the proportion of CC genotype increased in male of HT group( P=0.076). However, there is no significant difference in genotype and allele frequencies between control group and HT group after stratification by sex. In addition, the percentage of FcγRⅡb on B cell surface decreased significantly in HT group( P=0.029). Conclusion:There was no significant correlation between FcγRⅡb polymorphism and the down-regulation of FcγRⅡb protein on B cell surface in Hashimoto′s thyroiditis patients, and FcγRⅡb can be a predisposed factor for Hashimoto′s thyroiditis.

Objective:To compare the nutritional evaluation methods and to analyze the clinical value of different nutritional evaluation indexes in acute lymphoblastic leukemia (ALL) pediatric patients during the stage of remission induction.Methods:The clinical data of 132 ALL pediatric patients who were diagnosed and treated with remission induction in Shanghai Children′s Medical Center, School of Medicine, Shanghai Jiao Tong University from January 2018 to December 2020 were collected by convenient sampling method. The body composition was measured by direct segmental multifrequency bioelectrical impedance measurement (DSM-BIA), and the height, weight, upper arm circumference and triceps skinfold thickness were also measured. The Screening Tool for the Assessment of Malnutrition in Pediatrics scores were calculated. The serum albumin value and the hemoglobin value were monitored. Using DSM-BIA as the reference standard, the accuracy of different nutritional evaluation indexes was investigated and analyzed.Results:During the stage of remission induction in ALL pediatric patients, there were 69 out of 132 children who had the muscle mass below normal. The muscle mass below normal was detected in 52.3% (69/132). And the upper arm circumference had the highest correlation and the minimal standard error with muscle mass measured by DSM-BIA ( R2=0.520, SE=0.180). Grouped with nutritional status by the upper arm circumference, the children with normal nutritional status had lower incidence of very severe neutropenia 76.8% (24/32) than 92.1% (70/76) with abnormal nutritional status ( χ2=6.14, P=0.013). Conclusions:During the stage of remission induction in ALL pediatric patients, the malnutrition rate is high. The upper arm circumference is a simple index which can accurately reflect the nutritional status of the ALL pediatric patients. It is suggested that the upper arm circumference should be used as the primary screening index of clinical nutrition by clinical nurses.
