Chronic heart failure （CHF） is a complex clinical syndrome caused by ventricular dysfunction， with mitochondrial energy metabolism disorder being a critical factor in disease progression. Heart-Yang deficiency syndrome， as the core pathogenesis of CHF， persists throughout the disease course. Insufficiency of heart-Yang leads to weakened warming and propelling functions， resulting in the accumulation of phlegm-fluid， blood stasis， and dampness. This eventually causes Qi stagnation with phlegm obstruction and blood stasis with water retention， forming a vicious cycle that exacerbates disease progression. According to the theory of reinforcing Yang， the clinical experience of the traditional Chinese medicine （TCM） master Tang Zuxuan in treating CHF with heart-Yang deficiency syndrome， and achievements from molecular biological studies， this study innovatively proposes an integrated research framework of "TCM syndrome differentiation and staging-mitochondrial metabolism mechanisms-intervention with Yang-reinforcing prescriptions" which is characterized by the integration of traditional Chinese and Western medicine. Heart-Yang deficiency syndrome is classified into mild （Stage Ⅰ-Ⅱ）， severe （Stage Ⅲ）， and critical （Stage Ⅳ） stages. The study elucidates the precise correlations between the pathogenesis of each stage and mitochondrial metabolism disorders from theoretical， pathophysiological， and therapeutic perspectives. The mild stage is characterized by impaired biogenesis and substrate-utilization imbalance， corresponding to heart-Yang deficiency and phlegm-fluid aggregation. Linggui Zhugantang and similar prescriptions can significantly improve the expression of peroxisome proliferator-activated receptor gamma co-activator-1α（PGC-1α）/silent information regulator 2 homolog 1 （SIRT1） and ATPase activity. The severe stage centers on oxidative stress and structural damage， reflecting Yang deficiency with water overflow and phlegm-blood stasis intermingling. At this stage， Zhenwu Tang and Qiangxin Tang can effectively mitigate oxidative stress damage， increase adenosine triphosphate （ATP） content， and repair mitochondrial structure. The critical stage arises from calcium overload and mitochondrial disintegration， leading to the collapse of Yin-Yang equilibrium. At this stage， Yang-restoring and crisis-resolving prescriptions such as Fuling Sini Tang and Qili Qiangxin capsules can inhibit abnormal opening of the mitochondrial permeability transition pore （MPTP）， reduce cardiomyocyte apoptosis rate， and protect mitochondrial function. By summarizing the characteristics of mitochondrial energy metabolism disorders at different stages of CHF， this study explores the application of the theory of reinforcing Yang in treating heart-Yang deficiency syndrome and provides new insights for the clinical diagnosis and treatment of CHF.

A serum metabolomics analysis method based on gas chromatography-mass spectrometry(GC-MS) was used to investigate the metabolic regulation mechanism of Hericium erinaceus(H. erinaceus) polysaccharides on radiation injury. A mouse model of radiation injury was established by ~(60)Co-γ irradiation. High and low dose groups of H. erinaceus polysaccharide injection were designed, and Rubiae Radix et Rhizoma extract was set as the positive control group to investigate the therapeutic effects and metabolic reaction pathways of H. erinaceus polysaccharides on radiation injury. The metabolites of serum samples were collected by GC-MS, and principal component analysis(PCA) was conducted to establish the metabolic profiles of each group of mice. Partial least squares discriminant analysis(PLS-DA), t-test(P<0.05), and variable importance in the projection(VIP>1) were used to screen out the differential metabolite. Metabolite identification and construction of related metabolic pathways and metabolic networks were achieved by using online databases such as HMDB and METLIN. The results showed that 12 differential metabolites in the serum of mice irradiated at 6.5 Gy that were associated with the radiation injury model, including lactic acid, alanine, urea, serine, threonine, glycerol, L-5-oxoproline, L-lysine, stearic acid, stearic acid, oleic acid, and 1-monopalmitoylglucoside. Two metabolic pathways were enriched: glycerolipid metabolism and metabolism of glycine, serine, and threonine. 18 differential metabolites in the serum of mice irradiated at 8.5 Gy were associated with the radiation injury model, including lactic acid, alanine, urea, L-leucine, glycerol, nonanoic acid, serine, threonine, L-5-oxoproline, phenylalanine, L-ornithine, 1,5-dehydroorbital, L-lysine, L-tyrosine, pectic, oleic, stearic, and cholesterol. Four metabolic pathways were enriched: phenylalanine, tyrosine, and tryptophan synthesis, phenylalanine metabolism, glyceride metabolism, and glycine, serine, and threonine metabolism. It was suggested that H. erinaceus polysaccharides could intervene in radiation injury by altering amino acid and fatty acid synthesis in mice. It was assumed that H. erinaceus polysaccharides regulated the level of metabolic pathways through lipid metabolism and amino acid metabolism, thus affecting energy metabolism and amino acid metabolism and exerting its therapeutic effect on radiation damage.

To clarify the occurrence and distribution of broad bean wilt virus 2(BBWV2) on Rehmannia glutinosa, this study collected 87 R. glutinosa samples with typical symptoms of viral disease such as chlorosis and crumple from Wenxian county and Wuzhi county in Jiaozuo city, Henan province and Qiaocheng district in Bozhou city, Anhui province. The BBWV2 CP target band was amplified from 37 R. glutinosa samples by RT-PCR technology. The total detection rate reached 42.5%, among which 43.0% was detected in samples from Henan province. The detection rate in samples from Anhui province was 37.5%. 37 BBWV2 CP sequences were obtained by cloning and sequencing of BBWV2 positive samples(data has been submitted to GenBank, accession numbers: PP407959-PP407995), and the sequence analysis of these CP sequences with 91 other BBWV2 isolates in GenBank showed a high genetic diversity with a consistency rate of 70.8%-100%. Meanwhile, phylogenetic analysis showed that BBWV2 could be divided into three groups according to CP sequences, among which the BBWV2 in R. glutinosa isolates obtained in this study were all located in group 3. This study identified the differences in the occurrence, distribution, and genetic diversity of BBWV2 in R. glutinosa from Henan province and Anhui province and provided a theoretical basis for the prevention and control of BBWV2.

OBJECTIVE: To explore the clinical effect of personalized puncture planning before surgery using Picture Archiving and Communication System (PACS) in the treatment of osteoporotic vertebral compression fractures in the elderly. METHODS: A total of 69 elderly patients with osteoporotic vertebral compression fractures treated by percutaneous vertebroplasty from January 2020 20 to December 2021 with more than 1 year of follow-up were analyzed retrospectively. Thirty-four patients were individualized for preoperative planning with PACS software (observation group), including 8 males and 26 females, with a mean age of (73.30±7.96) years old;and 35 patients were treated with conventional treatment (control group), including 7 males and 28 females, with a mean age of (77.30±7.84) years old. The operation time, the amount of cement injection, cement leakage rate, bone watertight diffusion and refracture within 1 year between two groups were observed and compared. The Cobb's angle, low back pain visual analogue scale(VAS) and the modified Oswsetry disability indexes(ODI) before surgery and 1 day, 1 year after surgery were compared between two groups. RESULTS: Both groups successfully completed the operation without serious surgical complications, 2 refractures occurred in the control group. The operation time in the observation group was(41.9±11.9) min, which was less than that in the control group (52.7±13.6) min (P<0.05). There was no significant difference in the cement injection volume between two groups (P>0.05). Two cases of cement leakage in the observation group was less than 8 in the control group (P<0.05). The bone cement distribution index of two groups had significant difference(P<0.05). There were no significant differences between two groups in Cobb's angle of the injured vertebras and ODI before and 1 day after surgery(P>0.05), however, the comparative differences were statistically significant at 1 year after surgery(P<0.05). There was no significant difference in the VAS between two groups at each time period(P>0.05). CONCLUSION Using the PACS software to plan personalized puncture scheme can reduce the operation time, reduce the cement leakage rate, improve the diffusion of bone cement and longer maintain the postoperative form of vertebral body and the functional state of patients' lumbar back.

OBJECTIVE: To investigate the effect of traditional Chinese Five-body balance exercise on patients with preserved ratio impaired spirometry (PRISm). METHODS: Fifteen patients with PRISm and 15 patients diagnosed with chronic obstructive pulmonary disease (COPD) were recruited from the Outpatient Department of Guang'anmen Hospital and Beijing Niujie Health Service Center from April to December, 2023. Participants in both groups attended supervised Five-body balance exercise training twice a week for 12 weeks. Patients with COPD continued their regular medication regimen during the intervention period. The endpoints were mean changes in the 6-min walk test (6MWT), St. George's Respiratory Questionnaire (SGRQ) score, cardiopulmonary exercise testing (CPET), pulmonary function, and scores of COPD assessment test (CAT), modified British Medical Research Council, Self-Rating Anxiety Scale, and Self-Rating Depression Scale from baseline to 12 weeks. Adverse events were monitored throughout the study. RESULTS: The PRISm group showed a significant improvement from baseline to week 12 in 6MWT, SGRQ symptom score, and forced vital capacity (FVC) compared to the COPD group (P<0.05). No significant between-group changes were observed in other outcome measurements (P>0.05). In addition, compared with baseline, both groups exhibited improvements in 6MWT, SGRQ score, and CPET at week 12 (P<0.05). The PRISm group also showed a significant increase in forced expiratory volume in 1 s and FVC, as well as a significant decrease in CAT score at week 12 (P<0.05). No adverse events were reported. CONCLUSION Patients with PRISm may benefit from Five-body balance exercise training, which can improve the exercise capacity, health-related quality of life, and lung function.

Objective:To investigate the efficacy of sigmoid sinus constriction plus cartilage reconstruction technique for sigmoid sinus related pulsatile tinnitus. Methods:The clinical data of 31 patients with Sigmoid Sinus Diverticulum（SSD） who underwent surgical treatment from January 2020 to December 2023 were retrospectively analyzed. The surgical methods include transmastoid sigmoid sinus constriction and cartilage reconstruction, transmastoid sigmoid sinus（bone wax） return surgery. Among them, 15 patients had transmastoid sigmoid sinus strictation + cartilage reconstruction, and transmammary sigmoid sinus（bone wax） in 16 cases. The aesthetic of anesthesia include general and local anesthesia, 20 cases of general anesthesia, 11 cases of local anesthesia. The doctors of our team graded the degree of tinnitus in 1 week, 1 month and 3 months（Tinnitus Evaluation Questionnaire, TEQ）, and compared the degree of preoperative tinnitus to evaluate the surgical efficacy, and the intraoperative and postoperative complications were analyzed and summarized. Results:In 30 of 31 patients, tinnitus was cured or improved with satisfactory efficacy. Among the patients undergoing sigmoid sinus constrictation + cartilage reconstruction, one case had intraoperative sigmoid sinus rupture and bleeding; among the patients who underwent sigmoid sinus（bone wax） return, one patient did not improve postoperative tinnitus, and one patient had postoperative headache and blurred vision, which improved after 1 month of conservative treatment. Conclusion:In the treatment of intravenous pulsatile tinnitus caused by sigmoid sinus diverticulum, the precision of the return depth is difficult to control, and the insufficient and excessive return will cause poor efficacy and postoperative complications. Based on the observation of small sample size and recent curative effect, it is considered that the sigmoid sinus constriction + cartilage reconstruction technology has certain advantages in surgical efficacy, with few postoperative complications, but the operation is difficult, so pay attention to the prevention and emergency treatment of intraoperative sigmoid sinus rupture bleeding.

Objective To investigate the effects of ischemia time and storage periods on RNA quality in fresh-frozen breast cancer(BC)and esophageal cancer(EC)tissue samples in order to establish evidence-based protocols for biobank sample management.Methods The tumor(T)and paired normal(N)tissue samples from 6 cases of BC and 6 cases of EC were collected and cryopreserved in Biobank,Shantou Central Hospital.Mirror paraffin-embedded tissues were simultaneously prepared into sections for morphological analysis.The samples were divided into two groups of<15 min and 15-30 min according to ischemia time,and RNA quality was analyzed at 4 storage periods of 8-10 months(T1),14-16 months(T2),26-28 months(T3)and 38-40 months(T4).Results In 96 analyzed samples,93.8%(90/96)exhibited high quality(RIN≥6),with 89.6%(43/48)in BC and 97.9%(47/48)in EC.Significant differences in RIN were observed between BC group and EC group(8.050 vs.8.600,P=0.009).In EC group,RIN value was significantly negatively correlated with RNA yield(P<0.001).Moreover,RIN values of tumor-normal pairs exhibited markedly significant differences(7.550 vs.9.000,P<0.001).In contrast,no significant difference was detected in BC group(8.200 vs.7.700,P=0.348).Statistical analysis showed that RIN value was positively correlated with 28S/18S(P<0.001),but had no correlation with tumor content(P=0.676)and necrotic content(P=0.055).Neither ischemia time(<15 min vs.15-30 min:8.200 vs.8.300,P=0.932)nor storage periods(T1-T4:8.400,7.700,8.450,8.600,P=0.163)compromised RNA quality.Conclusion Organ origin and tissue type could influence RNA quality of fresh-frozen tissue samples.However,limited ischemia time(≤30 min)and long-term storage period(38-40 months)do not adversely affect RNA quality in fresh-frozen breast cancer and esophageal cancer tissue samples.

Objective:To explore the role of the expression of peroxisome proliferator-activated receptor β/δ(PPARβ/δ)in the anti-inflammatory mechanism of acupuncture(AC)against cerebral ischemia-reperfusion injury(CIRI)in rat hippocampal tissue.Methods:A total of 60 SD rats were randomly divided into Sham group,CIRI group,CIRI+AC group and CIRI+AC+PPARβ/δsiRNA group.The CIRI rat model was prepared by the method of middle cerebral artery occlusion,and acupuncture treatment was used for intervention.The neurological function of rats was assessed by the modified neurological severity score(mNSS)method after 72 hours of intervention.The brain in-farction volume ratio was observed by 2,3,5-triphenyltetrazolium chloride(TTC)staining method.The pathological morphological changes of brain tissue were observed by hematoxylin-eosin(HE)staining.The expression levels of PPARβ/δ,IL-1β,and IL-10 mRNA in the hippocampal region were detected by RT-qPCR.Results:Compared with the Sham group,the mNSS scores and the brain infarction volume ratio in all modeling groups were significantly in-creased.Compared with the CIRI group,the mNSS scores and the brain infarction volume ratio in the CIRI+AC group were significantly reduced.The expression levels of PPARβ/δ and IL-10 in the hippocampus were significantly upregu-lated,while the expression level of IL-1β was significantly downregulated(P<0.01),with scattered inflammatory cell infiltration observed.Compared with the CIRI+AC group,there was no significant difference in the mNSS scores and the brain infarction volume ratio in the CIRI+AC+PPARβ/δsiRNA group.The expression level of PPARβ/δ in the hippocampus was significantly downregulated(P<0.01),while no significant difference was found in the expression level of IL-10 and IL-1β mRNA,with a small amount of inflammatory cell infiltration observed.Conclusion:Acupunc-ture ameliorates the recovery of neurological function and the ratio of cerebral infarction volume in rats with CIRI,and its mechanism may be associated with the upregulation of PPARβ/δ expression,thereby reducing inflammatory respon-ses and exerting neuroprotective effects.

Objective:To investigate the effects of acupuncture intervention on the expression of circRNA_017109 and miR-138-5p in the hippocampal region of rats with cerebral ischemia-reperfusion injury(CIRI),and to explore the potential mechanism of acupuncture in treating CIRI.Methods:Forty-five Sprague-Dawley(SD)rats were divided into sham group,middle cerebral artery occlusion/reperfusion(MCAO/R)group,and acupuncture(MCAO/R+AC)group.The MCAO/R and MCAO/R+AC groups were subjected to the modified Longa suture method to establish the MCAO/R model.The MCAO/R+AC group received acupuncture at the"Dazhui","Renzhong",and"Baihui"acu-points.Neurological impairment was assessed via the modified neurological severity score(mNSS).while cerebral infarct volume was assessed through TTC staining.Histological alterations in brain tissue were examined via HE stai-ning,and the expression of circRNA_017109 and miR-138-5p in the hippocampal area were determined using RT-qPCR.Results:The mNSS scores and cerebral infarct volume ratios in the model groups were markedly higher than those in the sham group(P<0.01),but these were significantly reduced in MCAO/R+AC group compared to the MCAO/R group(P<0.01).HE staining showed severe necrosis and inflammation in the MCAO/R group's hippocam-pus,while the MCAO/R+AC group had minimal necrosis and scattered inflammation.RT-qPCR results indicated that the expression of circRNA_017109 and miR-138-5p was downregulated in the MCAO/R group,while MCAO/R+AC group upregulated the expression of circRNA_017109 and miR-138-5p(P<0.05,P<0.01).Conclusion:Acupunc-ture can improve neurological deficits,reduce cerebral infarction volume,and alleviate inflammatory cell infiltration in CIRI rats by upregulating the expression of circRNA_017109 and miR-138-5p,thereby exerting neuroprotective effects.
