In PRP group, there were 10 males and 6 females, aged from 28 to 47 years old with an average of (36.75±7.14) years old;the time from injury to surgery ranged from 1 to 31 h with an average of (26.13±3.98) h;5 patients on the left side and 11 patients on the right side;PRP was injected once during operation and the 4th and 8th weeks after operation respectively. In control group, there were 8 males and 8 females, aged from 30 to 52 years old with an average of (38.50±5.48) years old; the time from injury to surgery ranged from 1 to 29 h with an average of (25.48±3.11) h;7 patients on the left side and 9 patients on the right side; minimally invasive surgical treatment was performed. Visual analogue scale(VAS) was used to evaluate pain and Constant-Murley score for shoulder joint function was used to evaluate the recovery of shoulder joint movement function before operation and 1, 3, 6, and 12 months after operation respectively.
RESULTS:
All patients were followed up for 12 to 28 months with an average of (18.3±5.2) months. All incisions patients healed well without adverse events such as infection. Postoperative VAS of PRP group at 1, 3, and 6 months were (5.5±1.2), (3.7±1.6), and (2.4±1.2), respectively, while were lower than those of control group (6.6±1.4), (4.9±1.1), and (3.7±1.3), respectively;and had statistical differences between two groups (P<0.05). There was no statistically significant difference in VAS between two groups before operation and 12 months after operation (P>0.05). Postoperative Constant-Murley scores of PRP group at 1, 3, and 6 months were (64.09±11.61), (73.19±12.89), and (82.61±14.81) points, respectively, which were higher than those of control group were (52.32±17.42), (61.65±14.43), and (72.52±11.04) respectively;and the differences were statistically significant (P<0.05). There was no statistically significant difference in Constant-Murley scores at 12 months after operation between two groups (P>0.05). In PRP group, there was no statistically significant difference at 6 months and 12 months after operation (P>0.05), while there were statistically significant differences at the other time points (1 month after operation compared with before operation, 3 months after operation compared with 6 months after operation, and 3 months after operation compared with 1 month after operation) (P<0.05). In control group, there was no statistically significant difference when comparing 1 month and 3 months after operation (P>0.05), while at the other time points (1 month after operation with before operation, 3 months after operation with 6 months after operation, and 6 months after operation with 12 months after operation), the differences were all statistically significant (P<0.05).

Journal of Geriatric Cardiology 2025;22(5):477-496
Cardiovascular damage caused by cancer treatment has become an important cause of death for tumor survivors. With the recognition of cardiovascular diseases and cancer therapy-related cardiovascular toxicity (CTR-CVT) in tumor patients, noninvasive imaging technologies play pivotal roles in the risk stratification, early diagnosis, monitoring and follow-up for CTR-CVT. In recent years, the field of cardio-oncology has witnessed continual updates in diagnostic and therapeutic strategies, with several pertinent guidelines and expert consensus documents issued in China and abroad. However, there remains a conspicuous absence of systematic guidance documents on the application of imaging techniques in the clinical practice of cardio-oncology. Therefore, the Chinese Anti-Cancer Association Society of Integrative Cardio-oncology, the Ultrasound Branch of the Chinese Medical Association, and the Chinese Society of Echocardiography convened experts to formulate the "Chinese guideline for the clinical application of noninvasive imaging technology in accessing cancer therapy-related cardiovascular toxicity". Building upon the systematic evaluation of guidelines and the latest evidence-based medical research in the field of cardio-oncology domestically and abroad, and in conjunction with data derived from evidence-based medical research in China, this guideline proposes noninvasive imaging examination methods and monitoring strategies for CTR-CVT, aiming to further standardize and guide the clinical practice of multidisciplinary physicians specializing in cardio-oncology in China.

OBJECTIVE:
To evaluate the clinical efficacy and safety of Yangxue Qingnao Pills (YXQNP) combined with amlodipine in treating patients with grade 1 hypertension.
METHODS:
This is a multicenter, randomized, double-blind, and placebo-controlled study. Adult patients with grade 1 hypertension of blood deficiency and Gan (Liver)-yang hyperactivity syndrome were randomly divided into the treatment or the control groups at a 1:1 ratio. The treatment group received YXQNP and amlodipine besylate, while the control group received YXQNP's placebo and amlodipine besylate. The treatment duration lasted for 180 days. Outcomes assessed included changes in blood pressure, Chinese medicine (CM) syndrome scores, symptoms and target organ functions before and after treatment in both groups. Additionally, adverse events, such as nausea, vomiting, rash, itching, and diarrhea, were recorded in both groups.
RESULTS:
A total of 662 subjects were enrolled, of whom 608 (91.8%) completed the trial (306 in the treatment and 302 in the control groups). After 180 days of treatment, the standard deviations and coefficients of variation of systolic and diastolic blood pressure levels were lower in the treatment group compared with the control group. The improvement rates of dizziness, headache, insomnia, and waist soreness were significantly higher in the treatment group compared with the control group (P<0.05). After 30 days of treatment, the overall therapeutic effects on CM clinical syndromes were significantly increased in the treatment group as compared with the control group (P<0.05). After 180 days of treatment, brachial-ankle pulse wave velocity, ankle brachial index and albumin-to-creatinine ratio were improved in both groups, with no statistically significant differences (P>0.05). No serious treatment-related adverse events occurred during the study period.
CONCLUSIONS
Combination therapy of YXQNP with amlodipine significantly improved symptoms such as dizziness and headache, reduced blood pressure variability, and showed a trend toward lowering urinary microalbumin in hypertensive patients. These findings suggest that this regimen has good clinical efficacy and safety. (Registration No. ChiCTR1900022470).

OBJECTIVE:
To explore the therapeutic effects and underlying mechanisms of Dendrobium officinale (Tiepi Shihu) extract (DOE) on insomnia.
METHODS:
Forty-two male Sprague-Dawley rats were randomly divided into 6 groups (n=7 per group): normal control, model control, melatonin (MT, 40 mg/kg), and 3-dose DOE (0.25, 0.50, and 1.00 g/kg) groups. Rats were raised in a strong-light (10,000 LUX) and -noise (>80 db) environment (12 h/d) for 16 weeks to induce insomnia, and from week 10 to week 16, MT and DOE were correspondingly administered to rats. The behavior tests including sodium pentobarbital-induced sleep experiment, sucrose preference test, and autonomous activity test were used to evaluate changes in sleep and emotions of rats. The metabolic-related indicators such as blood pressure, blood viscosity, blood glucose, and uric acid in rats were measured. The pathological changes in the cornu ammonis 1 (CA1) region of rat brain were evaluated using hematoxylin and eosin staining and Nissl staining. Additionally, the sleep-related factors gamma-aminobutyric acid (GABA), glutamate (GA), 5-hydroxytryptamine (5-HT), and interleukin-6 (IL-6) were measured using enzyme linked immunosorbent assay. Finally, we screened potential sleep-improving receptors of DOE using polymerase chain reaction (PCR) array and validated the results with quantitative PCR and immunohistochemistry.
RESULTS:
DOE significantly improved rats' sleep and mood, increased the sodium pentobarbital-induced sleep time and sucrose preference index, and reduced autonomic activity times (P<0.05 or P<0.01). DOE also had a good effect on metabolic abnormalities, significantly reducing triglyceride, blood glucose, blood pressure, and blood viscosity indicators (P<0.05 or P<0.01). DOE significantly increased the GABA content in hippocampus and reduced the GA/GABA ratio and IL-6 level (P<0.05 or P<0.01). In addition, DOE improved the pathological changes such as the disorder of cell arrangement in the hippocampus and the decrease of Nissel bodies. Seven differential genes were screened by PCR array, and the GABAA receptors (Gabra5, Gabra6, Gabrq) were selected for verification. The results showed that DOE could up-regulate their expressions (P<0.05 or P<0.01).
CONCLUSION
DOE demonstrated remarkable potential for improving insomnia, which may be through regulating GABAA receptors expressions and GA/GABA ratio.

Objective To investigate the effects of circ_UBE2C on the proliferation and glycolysis of lung cancer cells and its mechanism of action.Methods The expression of circ_UBE2C,miR-107,and hexokinase 2(HK2)in lung cancer tissues and normal lung tissues were analyzed based on the The Cancer Genome Atlas(TCGA)database.Kaplan-Meier survival curve was plotted to analyze the correlation between circ_UBE2C/miR-107/HK2 expression and survival of the lung cancer patients.qRT-PCR was used to detect the expression of circ_UBE2C and miR-107,and Western blotting was employed to measure the expression of HK2 and PCNA in human normal lung epithelial cells(BEAS-2B)and human lung cancer cell lines(A549,NCI-H460,and NCI-H1299).Then A549 and NCI-H1299 cells were divided into the blank group(NC),circ_UBE2C knockdown group(si-circ),HK2 knockdown group(si-HK2),simultaneous knockdown of miR-107+HK2 group(miR-inhibitor+si-HK2),and simultaneous knockdown of circ_UBE2C+miR-107 group(si-circ+miR-inhibitor).CCK-8 assay and colony formation assay were employed to measure the proliferation of above cell groups.The glucose uptake,lactate generation,and ATP production in the cells were measured by glucose uptake colorimetric assay kit,lactic acid detection kit,and ATP content determination kit,respectively.Seahorse XF glycolytic stress test and Seahorse XF cellular mitochondrial stress test were respectively performed to detect the extracellular acidification ratio(ECAR)and cellular oxygen consumption ratio(OCR).The targeting relationship between the circ_UBE2C and miR-107,and miR-107 and HK2 was validated by dual-luciferase reporter gene assay.Results Compared with normal lung tissues,the expression of circ_UBE2C and HK2 was up-regulated,while that of miR-107 was down-regulated in lung cancer tissues(P<0.05).The expression of circ_UBE2C and HK2 was elevated,and that of miR-107 was reduced in A549 and NCI-H1299 cells when compared with BEAS-2B cells(P<0.05).Survival analysis showed that the patients with high expression of circ_UBE2C and HK2 or low expression of miR-107 had shorter survival(P<0.05).Compared with the NC group,both si-circ and si-HK2 resulted in significantly reduced proliferation,glucose uptake,lactate generation,ATP production,and ECAR and OCR values in A549 and NCI-H1299 cells(P<0.05).Dual luciferase reporter gene assay confirmed that circ_UBE2C could directly bind to and negatively regulate miR-107 expression.HK2 was then identified as a downstream target of miR-107.Compared with the si-HK2 group,the proliferative ability and glycolysis level of A549 and NCI-H1299 cells were significantly increased in the miR-inhibitor+si-HK2 group and the si-circ+miR-inhibitor group.Conclusion Knockdown of circ_UBE2C significantly suppresses the proliferation and glycolysis of lung cancer cells via targeting up-regulation of miR-107 and then exerting inhibitory effect on HK2 expression.

With the development of molecular pharmacognosy, the advantages of DNA molecular markers in the identification of original plants of Chinese medicinal materials are becoming increasingly significant. To compensate for the limitations of existing markers in the quality supervision of Chinese medicinal materials, our team has independently designed a new molecular marker named DNA signature sequence(DSS). This marker is a nucleotide sequence that only appears in a specific taxonomic unit, with a length of 40 bp and high identification accuracy. This article aims to screen and verify the DSS markers that can accurately identify the original plants of the medicinal materials included in the volume one of the Chinese Pharmacopoeia, establish the operating procedure for developing standard nucleotide sequences, and lay a foundation for the widespread application of polymerase chain reaction in the quality supervision of traditional Chinese medicine. Firstly, the Chloroplast Genome Information Resource(CGIR) was searched for the chloroplast genome sequences of the test samples, species of the same genus, and common background species. IdenDSS was used to obtain the DSS tags and specific identification primers of the tested species. After DNA extraction, PCR amplification, sequencing, and sequence alignments, a total of 203 DSS markers of Chinese medicinal materials were obtained for validation. The above sequences were uploaded to the Traditional Chinese Medicine Molecular Identification Platform(www.herbsdna.com), and a standard DSS library was established for identifying the original plants of medicinal materials, serving as an important tool for quality supervision of Chinese materia medica. On this basis, an operating procedure for DSS development is formed, laying a foundation for further DSS screening and application based on more diverse genome sequences.

OBJECTIVES:
To study the clinical characteristics and prognosis of SARS-CoV-2 Omicron variant infection-associated acute necrotizing encephalopathy (ANE) in children .
METHODS:
A retrospective analysis was conducted on the medical data of 12 children with SARS-CoV-2 Omicron variant infection-associated ANE who were admitted to the Pediatric Intensive Care Unit, Qingdao Women and Children's Hospital from December 18 to 29, 2022. The children were divided into two groups based on outcomes: death group (7 cases) and survival group (5 cases). The clinical manifestations and auxiliary examination results were compared between the two groups.
RESULTS:
The median age of the 12 patients was 30 months, with a male-to-female ratio of 1:1. All patients presented with persistent high fever, with a median highest body temperature of 41℃. The median time from fever onset to seizure or consciousness disturbance was 18 hours. The death group had a higher proportion of neurogenic shock, coagulation dysfunction, as well as elevated lactate, D-dimer, interleukin-6, interleukin--8, and interleukin-10 levels compared to the survival group (P<0.05).
CONCLUSIONS
Children with SARS-CoV-2 Omicron variant infection-associated with ANE commonly present with persistent high fever, rapidly progressing disease, and have a high likelihood of developing consciousness disorders and multiorgan dysfunction within a short period. The occurrence of neurogenic shock, coagulation dysfunction, and significantly elevated cytokine levels suggests an increased risk of mortality.

Objective:To explore the prognostic evaluating value of serum tenascin-X in patients with acute ST-segment elevation myocardial infarction (STEMI).Methods:The clinical data of 121 patients with STEMI in the Affiliated Sinopharm Dongfeng General Hospital, Hubei University of Medicine from August 2017 to August 2018 were retrospectively analyzed. The clinical data were collected, the serum tenascin-X level was measured by enzyme-linked immunosorbent assay. The patients were followed up for 3 years, the major adverse cardiovascular events (MACE) were identified as endpoint events. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum tenascin-X for MACE in patients with STEMI. The Kaplan-Meier survival curve was drawn, the rates of non-MACE survival in patients with different serum tenascin-X levels were analyzed by log-rank method. Multivariate Cox regression was used to analyze the independent risk factors of MACE in patients with STEMI.Results:Until the end of follow-up, among 121 patients with STEMI, 42 cases (34.7%) developed MACE (MACE group), and 79 cases had not MACE (non-MACE group). The left ventricular ejection fraction (LVEF) in the MACE group was significantly lower than that in the non-MACE group: (47.14 ± 6.70)% vs. (52.67 ± 4.41)%, the C-reactive protein (CRP), B-type natriuretic peptide (BNP), cardiac troponin I (cTnI) and tenascin-X were significantly higher than those in non-MACE group: (27.92 ± 8.06) mg/L vs. (8.77 ± 3.49) mg/L, (918.31 ± 315.47) μg/L vs. (220.47 ± 108.37) μg/L, (214.73 ± 80.46) μg/L vs. (81.35 ± 28.96) μg/L and (110.67 ± 42.55) μg/L vs. (65.21 ± 28.06) μg/L, and there were statistical differences ( P<0.01). ROC curve analysis result showed that the area under the curve of serum tenascin-X to predict the MACE in patients with STEMI was 0.806 (95% CI 0.724 to 0.872), and the optimal cut-off was 93.25 μg/L, the sensitivity was 69.0%, the specificity was 86.1%. Kaplan-Meier survival curve analysis result showed that the rate of non-MACE in 80 patients with low serum tenascin-X level (<93.25 μg/L) was significantly higher than that in 41 patients with high serum tenascin-X level (≥93.25 μg/L): 83.8% vs. 29.3%, and there was statistical difference ( χ2 = 42.47, P<0.01). Multivariate Cox regression analysis result showed that the CRP, BNP and tenascin-X were the independent risk factors of MACE in patients with STEMI ( HR = 1.092, 1.001 and 1.018; 95% CI 1.051 to 1.135, 1.000 to 1.002 and 1.008 to 1.027; P<0.01 or <0.05). Conclusions:The significant increase in serum tendon protein X levels in patients with STEMI has predictive value for the MACE, and it is an independent predictor of MACE within 3 years.

Wilt disease is a major disease of cultivated Salvia miltiorrhiza, which is caused by Fusarium oxysporum. Since the infection process of F. oxysporum in plants is affected by environment factors, this study was conducted to reveal the relationship between disease severity and concentration of the pathogen in plants in the infection process of F. oxysporum in seedlings of S. miltiorrhiza by pot experiments and to reveal the effects of temperature and humidity on the infection process. The results showed that, after inoculation of S. miltiorrhiza seedlings with F. oxysporum, the pathogen in different parts was detected at different time, and it was first detected in substrates. With the continuous propagation of the pathogen(4-5 d), it gradually infected the roots and stems of the seedlings, and the plants had yellowing leaves and withering. The number of the pathogen reached the maximum in each part after 7-8 d, and then gradually decreased in the later stage of the disease. The concentration of the pathogen in substrates, roots and stems of S. miltiorrhiza showed a trend of decreasing after increasing with the aggravation of the disease and reached the maximum in the samples of moderate morbidity, while the concentration in the samples of severe morbidity decreased. In addition, the infection of F. oxysporum in seedlings of S. miltiorrhiza was affected by temperature and humidity. The suitable temperature was 25-30 ℃ and the suitable humidity was 80%-90%. This study could provide guidance for the experiments on pathogenicity of F. oxysporum, screening of biocontrol bacteria and controlling of wilt.

Objective: To investigate the expression of CD24 gene in human malignant pleural mesothelioma (MPM) cells and tissues, and evaluate its relationship with clinicopathological characteristics and clinical prognosis of MPM patients. Methods: In February 2021, UALCAN database was used to analyze the correlation between CD24 gene expression and clinicopathological characteristics in 87 cases of MPM patients. The TIMER 2.0 platform was used to explore the relationship between the expression of CD24 in MPM and tumor immune infiltrating cells. cBioportal online tool was used to analyze the correlation between CD24 and MPM tumor marker gene expression. RT-qPCR was used to analyze the expressions of CD24 gene in human normal pleural mesothelial cell lines LP9 and MPM cell lines NCI-H28 (epithelial type), NCI-H2052 (sarcoma type), and NCI-H2452 (biphasic mixed type). RT-qPCR was performed to detect the expressions of CD24 gene in 18 cases of MPM tissues and matched normal pleural tissues. The expression difference of CD24 protein in normal mesothelial tissue and MPM tissue was analyzed by immunohistochemistry. A Kaplan-Meier model was constructed to explore the influence of CD24 gene expression on the prognosis of MPM patients, and Cox regression analysis of prognostic factors in MPM patients was performed. Results: The CD24 gene expression without TP53 mutation MPM patients was significantly higher than that of patients in TP53 mutation (P<0.05). The expression of CD24 gene in MPM was positively correlated with B cells (r(s)=0.37, P<0.001). The expression of CD24 gene had a positive correlation with the expressions of thrombospondin 2 (THBS2) (r(s)=0.26, P<0.05), and had a negative correlation with the expression of epidermal growth factor containing fibulin like extracellular matrix protein 1 (EFEMP1), mesothelin (MSLN) and calbindin 2 (CALB2) (r(s)=-0.31, -0.52, -0.43, P<0.05). RT-qPCR showed that the expression level of CD24 gene in MPM cells (NCI-H28, NCI-H2052 and NCI-H2452) was significantly higher than that in normal pleural mesothelial LP9 cells. The expression level of CD24 gene in MPM tissues was significantly higher than that in matched normal pleural tissues (P<0.05). Immunohistochemistry showed that the expressions of CD24 protein in epithelial and sarcoma MPM tissues were higher than those of matched normal pleural tissues. Compared with low expression of CD24 gene, MPM patients with high expression of CD24 gene had lower overall survival (HR=2.100, 95%CI: 1.336-3.424, P<0.05) and disease-free survival (HR=1.800, 95%CI: 1.026-2.625, P<0.05). Cox multivariate analysis showed that compared with the biphasic mixed type, the epithelial type was a protective factor for the prognosis of MPM patients (HR=0.321, 95%CI: 0.172-0.623, P<0.001). Compared with low expression of CD24 gene, high expression of CD24 gene was an independent risk factor for the prognosis of MPM patients (HR=2.412, 95%CI: 1.291-4.492, P=0.006) . Conclusion: CD24 gene and protein are highly expressed in MPM tissues, and the high expression of CD24 gene suggests poor prognosis in MPM patients.
