ObjectiveTo investigate the inhibitory effect of Biejia Decoction Pill on the proliferation， migration， and aerobic glycolysis of hepatocellular carcinoma （HCC） using cell experiments， as well as related mechanisms. MethodsHuman liver cancer cell line Huh7 was selected， and Sprague-Dawley rats were randomly divided into blank serum group， inhibitor group， and high-， middle-， and low-dose Biejia Decoction Pill groups. Rat serum containing the drug was prepared for the incubation of Huh7 cells. CCK8 assay and scratch assay were used to explore the effect of Biejia Decoction Pill on the proliferation and migration of HCC cells； glycolytic rate-limiting enzymes and metabolites were measured to explore the effect of Biejia Decoction Pill on aerobic glycolysis of liver cancer cells； RT-qPCR and Western blot were used to explore the effect of Biejia Decoction Pill on the mRNA expression， related proteins， and phosphorylation of the protein kinase B （AKT）/mammalian target of rapamycin （mTOR） signaling pathway. A one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test or the Dunnett’s T3 test were used for further comparison between two groups. ResultsCompared with the blank serum group， the Biejia Decoction Pill groups had significant reductions in OD value， migration rate during different periods of time， glycolytic rate-limiting enzymes （hexokinase， phosphofructokinase， pyruvate kinase）， and glycolytic metabolites （pyruvate， lactic acid， ATP） （all P<0.05）. RT-qPCR results showed that compared with the blank serum group， the high-， middle-， and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of mTOR， and the high- and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of AKT （all P<0.05）. Western blot results showed that compared with the blank serum group， the high-， middle-， and low-dose Biejia Decoction Pill groups had significant reductions in the expression levels of mTOR-related proteins and phosphorylated proteins， and the high- and middle-dose Biejia Decoction Pill groups had significant reductions in the expression levels of AKT-related proteins and phosphorylated proteins （all P<0.05）. ConclusionThis study preliminarily verifies that the serum containing Bijia Decoction Pill can inhibit the aerobic glycolysis of human hepatoma Huh7 cells， thereby inhibiting their proliferation and migration， possibly by inhibiting the expression of the proteins related to the AKT/mTOR signaling pathway.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective:To explore the association between frailty index (FI) and the risk for cardiovascular disease (CVD) in adults in Inner Mongolia Autonomous Region, and provide new evidence for the prevention of CVD in adults in Inner Mongolia Autonomous Region.Methods:The FI was constructed by using the data from a prospective cohort with a sample size of 25 055 individuals in 6 years of follow-up, and the prevalence of frailty in adults in Inner Mongolia Autonomous Region was described by the FI, and Cox proportional hazard regression model was used to evaluate the association between the FI and the incidence of CVD in adults in Inner Mongolia Autonomous Region.Results:The FI of the study population was 0.24±0.09. The population in the pre-frail (FI: 0.21-0.27) and frail (FI≥0.28) phases had increased risk for CVD compared to non-frail (FI≤0.20) population [pre-frail: hazard ratio ( HR)=1.232, 95% CI: 1.127-1.347; frail phase: HR=1.418, 95% CI:1.299-1.548]. For every 0.10 increase in FI, the risk for cardiovascular disease increased by 20.3% ( HR=1.203,95% CI:1.156-1.252). Conclusions:In this study, we constructed a FI, which can suggest the risk for CVD. As the increase of frailty degree, the risk for CVD increases.

Objective:To describe the characteristics, etiology and patterns of outpatients and inpatients patients with moderate or severe valvular heart disease (VHD).Methods:This is a cross-sectional study. Outpatients and inpatients with moderate or severe VHD who underwent transthoracic echocardiography for first examination from 1 st January 2001 to 1 st January 2020 in Southwest Hospital, Army Medical University were enrolled. Data were collected from medical records and big data platform of Southwest Hospital. Characteristics of age and gender, etiology and types of VHD were descriptively analysed. Results:A total of 68 354 patients with moderate or severe VHD were enrolled. The age was 63 (50, 72) years. And 35 706 (52.24%) patients were female. (1) Age characteristics: There was similar age trend between male and female patients with moderate or severe VHD. The number of patients increased firstly and then decreased and reached its peak in the age group of 65-69 years old. The peak age of mitral stenosis patients was 45-49 years, which was earlier than that of whole patients with moderate or severe VHD. The median age of patients with bicuspid aortic valve was 42 years. (2) Gender characteristics: The proportion of tricuspid regurgitation, pulmonary regurgitation, mitral regurgitation, mitral stenosis and valve surgery in female patients with moderate or severe VHD were higher than those in male patients. The proportion of aortic regurgitation, aortic stenosis and bicuspid aortic valve in male patients with moderate or severe VHD were significantly higher than those in female patients (all P<0.05). (3) Etiology: The proportion of rheumatic VHD was 13.07% (8 934/68 354), which was higher than that of degenerative VHD (0.67% (458/68 354)). (4) Types of VHD: Tricuspid regurgitation made contribution to the largest proportion with 60.72% (41 503/68 354), followed by mitral regurgitation, aortic regurgitation, mitral stenosis, pulmonary regurgitation and aortic stenosis. Conclusions:There are certain regional characteristics in the prevalence of moderate or severe VHD in southwest China, suggesting different attention should be paid on the whole process of refined management of moderate or severe VHD.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective:To study the regulatory relationship between the loci single nucleotide polymorphism(SNP) rs9268832 and susceptibility gene human leukocyte antigen(HLA) DRB1 in systemic lupus erythematosus (SLE), and to enhance the understanding of genetic susceptibility to SLE.Methods:①A total of 223 out-and inpatients with SLE and 2 223 healthy controls were collected from Weihai Municipal Hospital from September 2017 to September 2019, and the SNP sites that might significantly associated with SLE were screened by genome-wide association study. ②Sequencing technology was used to genotype 100 out and -in patients with SLE and 100 healthy controls in Weihai Municipal Hospital from December 2019 to December 2020, the levels of anti-nuclear antibody and anti-double-stranded DNA antibody were detected by indirecte immunofluorescence and chemiluminescence immunoassay. Real-time quantitative PCR was used to determine HLA-DRB1 mRNA expression in peripheral blood mononuclear cells and B lymphocytes of 100 patients with SLE. ③One-way analysis of variance was used in this study, and SNK- q test or Tamhane′s T2 test were used for comparison between groups. Results:①A number of SNPs associated with SLE were identified by genome-wide association studies. Rs9268832, located in the HLA-DR region of susceptibility genes, was significantly associated with antinuclear antibodies. ②Of the 100 SLE patients, 41 had TT genotype of rs9268832, 32 had CT genotype, and 27 had CC genotype. In the 100 normal subjects, 10 had TT genotype of rs9268832, 59 had CT genotype, and 31 had CC genotype. The distribution frequency of T allele in SLE patients is higher than in normal people( χ2=27.58, P=0.020). ③Indirecy immunofluorescence and Chen iluminescence results showed that compared with CC genotype [antinuclear antibody (23.5±1.2)U/ml, anti-double-stranded DNA antibody (16.6±0.9)U/ml], CT genotype [antinuclear antibody (40.2±2.5)U/ml, anti-double-stranded DNA antibody (36.2±1.8)U/ml] were increased ( q=5.35, P=0.004; q=4.23, P=0.002), TT genotype [antinuclear antibody (56.3±3.1)U/ml, anti-double-stranded DNA antibody (52.5±2.9)U/ml] were increased ( q=8.21, P<0.001; q=7.59, P<0.001). PCR results showed that : compared with CC genotype [monocyte (402±8)×10 3, lymphocyte (462±7)×10 3], CT genotype [monocyte (572±11)×10 3, lymphocyte (470±8)×10 3] increased HLA-DRB1 mRNA expression ( q=1.11, P=0.030; q=1.03, P=0.040), TT genotype [monocytes (1 052±16)×10 3, lymphocytes (856±6)] increased HLA-DRB1 mRNA expression ( q=4.27, P=0.007; q=3.05, P=0.010). Conclusion:The T allele of SNP rs9268832 may be a risk locus for SLE, and there may be a regulatory relationship between different genotypes and the expression of susceptibility gene HLA-DRB1.

Objective:To investigate the feasibility and clinical diagnostic value of rapid arterial spin labeling (ASL) imaging in brain glioma.Methods:Patients with glioma admitted to Beijing Tiantan Hospital, Capital Medical University from May 2021 to December 2022 were prospectively enrolled. All patients received MR rapid ASL (scan time: 1 min) and conventional ASL (scan time: 4 min 30 s), where the cerebral blood flow (CBF) perfusion maps were obtained. The qualitative analysis of CBF signal intensity and quantitative analysis of average CBF values from both tumor solid and edema regions were conducted by two radiologists independently. Kappa test and intraclass correlation coefficient ( ICC) were used to analyze the consistency of qualitative and quantitative results, respectively. Results:A total of 30 patients with brain glioma were included. The 2 physicians used rapid ASL to determine low perfusion, isoperfusion, and hyperperfusion in the tumor area in 1, 6, 23 cases and 0, 5, and 25 cases, respectively; and used conventional ASL to determine low perfusion, isoperfusion, and hyperperfusion in the tumor area in 0, 9, and 21 cases, respectively. The results of qualitative analysis of rapid ASL and conventional ASL were highly consistent within and between groups ( Kappa was 0.830 and 0.850 respectively). The results of quantitative analysis of rapid ASL and conventional ASL were highly consistent within and between groups ( ICC 0.940—0.994). Conclusion:Rapid ASL with shorter scanning time could be applied in assessing tissue perfusion in brain glioma and contribute to the clinical diagnosis of gliomas.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Objective:To compare the clinical efficacy between the pressing tendon suture with a lateral anchor and the knotted suture with a lateral anchor in the treatment of severe rotator cuff tear under shoulder arthroscopy.Methods:A retrospective study was conducted of the 42 patients who had been treated at Department of Orthopedic Sports Medicine, Affiliated Hospital to Qingdao University from December 2018 to December 2019 for severe rotator cuff tear. They were 13 males and 29 females, with an age of (58.3±10.1) years (from 32 to 74 years). The injury was on the right side in 26 cases and on the left side in 16 cases. Of them, 22 received pressing tendon suture with a lateral anchor under shoulder arthroscopy and 20 knotted suture with a lateral anchor under shoulder arthroscopy. The flexion, abduction and external rotation of the shoulder, Visual Analog Scale (VAS) pain score, University of California-Los Angeles (UCLA) score, Constant-Murley shoulder score, American Shoulder and Elbow Surgeons (ASES) score and imaging MRI Sugaya grading were compared between the 2 groups 12 months after operation.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability between them ( P>0.05). At 12 months after operation, the pressing tendon suture group had better abduction and flexion of the shoulder, a lower VAS pain score and a higher ASES score than the knotted suture group, but the differences were insignificant ( P>0.05). At 12 months after operation, the pressing tendon suture group achieved significantly better external rotation (39.2°±11.7°) and significantly higher UCLA score (28.1±4.7) and Constant-Murley shoulder score (77.0±9.3) than the knotted suture group (29.8°±14.6°, 22.1±5.7 and 66.4±11.0) ( P<0.05). At 12 months after operation, the imaging MRI Sugaya grading was significantly lower for the pressing tendon suture group than that for the knotted suture group ( P<0.05). Conclusion:In the treatment of patients with severe rotator cuff tear under shoulder arthroscopy, the pressing tendon suture with a lateral anchor may lead to better clinical prognosis than the knotted suture with a lateral anchor.

Objective:To explore the relationship between blocking antibody and lymphocyte subsets in elderly patients (age≥35 years old) with recurrent spontaneous abortion(RSA).Methods:A retrospective case-control study was conducted on the patients with recurrent spontaneous abortion who met the inclusion criteria from October 2014 to September 2019 in the Reproductive Center of Women Health Center of Shanxi.They were divided into two groups according to their ages: 66 cases in RSA group and 334 cases in normal pregnant age group.The blocking antibody and lymphocyte subsets were detected by flow cytometry.Results:The negative rate of blocking antibody in elderly recurrent spontaneous abortion patients was 77.27% (51/66), which was not significantly different from that in normal gestational recurrent spontaneous abortion patients (83.53%(279/334)) ( P=0.221), but significantly higher than that in normal women (23.46%(42/179)) ( P=0.001). The blocking antibody′s blocking efficiency results showed that the CD3′s blocking efficiency of elderly recurrent spontaneous abortion patients (0.10 (-0.50, 0.60)) was significantly lower than that of normal women (0.60 (0.00, 1.30)), the difference was statistically( P=0.001). The CD8 blocking efficiency of elderly recurrent spontaneous abortion patients (0.00 (-0.60, 0.63)) was significantly lower than that of normal women (0.30 (0.00, 0.70)), the difference was statistically( P=0.016). Lymphocyte subsets showed that the CD8 + T cell ratio in elderly recurrent spontaneous abortion patients (26.93±7.25) was significantly lower than that in normal gestational recurrent spontaneous abortion patients (29.22±7.29), the difference was statistically significant ( P=0.020). The CD4 + /CD8 + ratio in elderly recurrent spontaneous abortion patients (1.64±0.99) was significantly higher than that in normal gestational age recurrent spontaneous abortion patients (1.37±0.50), the difference was statistically significant ( P=0.030). The ratio of natural killer cells in elderly recurrent spontaneous abortion patients (16.13±7.10) was significantly higher than that in normal women (14.04±2.35), the difference was statistically significant ( P=0.022), and higher than that in normal gestational age recurrent spontaneous abortion women (15.57±7.02). Conclusion:There were differences in lymphocyte subsets between elderly RSA patients and normal pregnant women, and the increase of natural killer cell ratio may be an important factor in the occurrence of RSA, especially in elderly RSA patients.
