Zishen Huoxue decoction (ZSHX) enhances cardiomyocyte viability following hypoxic stress; however, its upstream therapeutic targets remain unclear. Network pharmacology and RNA sequencing analyses revealed that ZSHX target genes were closely associated with mitophagy and apoptosis in the mitochondrial pathway. In vitro, ZSHX inhibited pathological mitochondrial fission following hypoxic stress, regulated FUN14 domain-containing protein 1 (FUNDC1)-related mitophagy, and increased the levels of mitophagy lysosomes and microtubule-associated protein 1 light chain 3 beta II (LC3II)/translocase of outer mitochondrial membrane 20 (TOM20) expression while inhibiting the over-activated mitochondrial unfolded protein response. Additionally, ZSHX regulated the stability of beta-tubulin through Sirtuin 5 (SIRT5) and could modulate FUNDC1-related synergistic mechanisms of mitophagy and unfolded protein response in the mitochondria (UPR^mt) via the SIRT5 and -β-tubulin axis. This targeting pathway may be crucial for cardiomyocytes to resist hypoxia. Collectively, these findings suggest that ZSHX can protect against cardiomyocyte injury via the SIRT5-β-tubulin axis, which may be associated with the synergistic protective mechanism of SIRT5-β-tubulin axis-related mitophagy and UPR^mt on cardiomyocytes.

Objective To explore the efficacy and safety of ticagrelor de-escalation and nicorandil therapy in elderly patients with acute coronary syndrome(ACS)after percutaneous coronary intervention(PCI).Methods A total of 300 elderly patients with ACS were selected from the Sixth and Seventh Medical Center of Chinese PLA General Hospital and Beijing Chaoyang Integrative Medicine Emergency Rescue and First Aid Hospital from November 2016 to June 2019,including 153 males and 147 females,aged>65 years old.All the patients received PCI,and all had double antiplatelet therapy(DAPT)scores≥2 and a new DAPT(PRECISE-DAPT)score of≥25.All patients were divided into two groups by random number table method before operation:ticagrelor group(n=146,ticagrelor 180 mg load dose followed by PCI,and ticagrelor 90 mg bid after surgery)and ticagrelor de-escalation + nicorandil group(n=154,ticagrelor 180 mg load dose followed by PCI,ticagrelor 90 mg bid+nicorandil 5 mg tid after surgery,changed to ticagrelor 60 mg bid+ nicorandil 5 mg tid 6 months later).Follow-up was 12 months.The composite end points of cardiovascular death,myocardial infarction and stroke,the composite end points of mild hemorrhage,minor hemorrhage,other major hemorrhage and major fatal/life-threatening hemorrhage as defined by the PLATO study,and the composite end points of cardiovascular death,myocardial infarction,stroke and bleeding within 12 months in the two groups were observed.Results The comparison of general baseline data between the two groups showed no statistically significant difference(P>0.05).There was also no significant difference in the composite end points of cardiovascular death,myocardial infarction and stroke between the two groups(P>0.05).The cumulative incidence of bleeding events in ticagrelor de-escalation + nicorandil group was significantly lower than that in ticagrelor group(P<0.05),while the composite end points of cardiovascular death,myocardial infarction,stroke and bleeding were also significantly lower than those in tecagrelor group(P<0.05).Conclusion In elderly patients with ACS,the treatment of ticagrelor de-escalation + nicorandil after PCI may not increase the incidence of ischemic events such as cardiovascular death,myocardial infarction or stroke,and it may reduce the incidence of hemorrhagic events.

ObjectiveTo systematically evaluate the distribution of traditional Chinese medicine（TCM） syndromes of primary osteoporosis（POP） in China by using evidence-based medicine methods， and to understand the distribution law of the syndromes. MethodChina National Knowledge Infrastructure（CNKI）， VIP Chinese Science and Technology Journal Database（VIP）， WanFang Data Knowledge Service Platform（WanFang） and China Biology Medicine（CBM） were searched to obtain representative literature， and each database was searched from the 1994 World Health Organization defined diagnostic criteria for osteoporosis until May 1， 2023. Two researchers independently screened literature according to the criteria， extracted data， and cross-checked them. Meta analysis was conducted using R4.1.3， and subgroup analysis was performed. ResultA total of 56 Chinese papers were included， involving 14 415 patients. After standardized classification of syndromes， 11 articles were excluded， and Meta analysis results of the ultimately included 45 Chinese articles showed that the distribution frequencies of liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome in 12 723 patients were 27%［95% confidence interval（CI） 0.24-0.31］， 32%（95% CI 0.29-0.36）， 36%（95% CI 0.30-0.42）. Subgroup analysis showed that there was a statistically significant difference in the distribution of the three TCM syndromes in the north and south（P<0.05）. In addition， the incidence of TCM syndrome fractures in different types of POP was 15%（95% CI 0.09-0.24） for liver-kidney Yin deficiency syndrome， 20%（95% CI 0.12-0.30） for spleen-kidney Yang deficiency syndrome， and 31%（95% CI 0.25-0.39） for kidney deficiency and blood stasis syndrome. ConclusionThe distribution of syndromes in POP patients is mainly kidney deficiency， accompanied by liver and spleen dysfunction. Liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome are all the main syndromes of POP and osteoporotic fractures， and kidney deficiency and blood stasis syndrome is most closely related to the development of osteoporotic fractures. The reference standards for syndrome determination among the included studies are inconsistent， and in the future， it is necessary to focus on their determination standards to obtain consensus research results， at the same time， conduct large-scale syndrome research to obtain representative research results， providing a basis for clinical practice and research.

Objective:To explore the assessment value of liver enzyme changes before and after hepatectomy on the prognosis of patients with primary hepatocellular carcinoma(HCC). Methods:A retrospective analysis was conducted on the clinical data of 421 patients with primary HCC who received at the First and Second Affiliated Hospitals of Xi'an Jiaotong University from January 2016 to December 2020.The univariate and multivariate COX regression analyses were used to screen the risk factors affecting the prognosis of patients with primary HCC,and the optimal cut-off value was selected to group the most valuable indicators among them,further analyzing the different factors among subgroups.The Kaplan-Meier method was used to assess the prognosis of the subgroups,and the survival curves were plotted and statistically tested. Results:Multivariate COX regression analysis revealed that Barcelona Clinic Liver Cancer(BCLC)stage,tumor number,alpha-fetoprotein(AFP),the quantitative change of γ-glutamyl transpeptidase(GGT)and total bilirubin(TBIL)before and after surgery were independent risk factors affecting the prognosis of patients with primary HCC(P＜0.01),and there were differences in hepatitis B virus surface antigen(HBsAg),TNM stage,BCLC stage,tumor size,tumor number,tumor differentiation degree,AFP,surgery type,intraoperative bleeding volume,postoperative albumin-bilirubin(ALBI)and white blood cell count between the high and low GGT variation groups(P＜0.05).Kaplan-Meier survival analysis showed that the prognosis of patients with primary HCC between the high and low GGT variation groups was significantly different,with a hazard ratio of 2.603 for mortality and 1.449 for recurrence(both P＜0.01). Conclusion:The quantitative change of GGT before and after hepatectomy has an evaluation value for the prognosis of patients with primary HCC,and the quantitative change of GGT greater than 29.5 is an independent risk factor for the prognosis of patients with primary HCC.

OBJECTIVES: To explore the effect of acupuncture and moxibustion on intestinal flora in the rats with diarrhea-predominant irritable bowel syndrome (IBS-D) based on 16S rDNA technique. METHODS: Ten rats were randomized from 58 SPF-grade male SD rats to be the blank group. The remained 48 rats were prepared to be IBS-D models by the modified method of acetic acid enema combined with binding tail-clip stress. Forty successfully-modeled rats were randomly divided into a model group, an acupuncture group, a moxibustion group and a western medication group, with 10 rats in each one. In the acupuncture group, the needle was inserted at bilateral "Zusanli" (ST 36) and remained for 15 min in each rat. In the moxibustion group, the suspending moxibustion was delivered at bilateral "Zusanli" (ST 36) for 15 min. The rats in the western medication group were given pinaverium bromide suspension (10 mL/kg) by intragastric administration. The above interventions were performed once daily for consecutive 14 days. The body mass and the score of fecal trait were compared before and after modeling, as well as after intervention in each group. Fecal water content, diarrhea index and colon transit time (CTT) were measured after modeling and intervention in the rats of each group separately. After intervention, the colonic morphology of rats in each group was observed, and using 16S rDNA technique, the intestinal flora was detected. RESULTS: After modeling, compared with the blank group, the body mass and CTT were reduced (P<0.01); fecal trait scores, fecal water contents and diarrhea index increased (P<0.01) in the other 4 groups. After intervention, the body mass and CTT of the rats decreased (P<0.01), and fecal trait score, fecal water content and diarrhea index increased (P<0.01) in the model group compared with those in the blank group. In the acupuncture group, the moxibustion group and the western medication group, when compared with the model group, the body mass and CTT were elevated (P<0.01), while fecal trait scores, fecal water contents and diarrhea index declined (P<0.01). Compared with the western medication group, fecal water content decreased in the acupuncture group and the moxibustion group (P<0.05), while CTT increased in the acupuncture group (P<0.01), the body mass increased and fecal trait score was dropped in the moxibustion group (P<0.05). The colonic mucosa structure was clear and complete, and there was no obvious inflammatory cell infiltration in the blank group. The mild interstitial edema of intestinal mucosa was presented with the infiltration of few inflammatory cells in the model group. There was the infiltration of few inflammatory cells in the mucosa of the acupuncture group, the moxibustion group and the western medication group. Compared with the blank group, the indexes of Richness, Chao1, ACE and Shannon decreased in the model group (P<0.05). Indexes of Richness, Chao1 and ACE increased in the acupuncture group and the moxibustion group (P<0.05), and the Richness index in the western medication group increased (P<0.05) when compared with those in the model group. The relative abundance of Bacteroidetes, Proteobacteria and Prevotella increased (P<0.05), and that of Firmicutes and Muribaculaceae decreased (P<0.05) in the model group compared with those in the blank group. When compared with the model group, the relative abundance of Bacteroidetes, Proteobacteria and Prevotella was reduced (P<0.05), while that of Firmicutes and Muribaculaceae increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group; and that of Actinobacteria and Bifidobacterium increased in the acupuncture group and the moxibustion group (P<0.05). Compared with the blank group, the relative abundance of lipopolysaccharide (LPS) biosynthesis was elevated (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis decreased (P<0.05) in the model group. The relative abundance of LPS biosynthesis was dropped (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group compared with those of the model group. CONCLUSIONS Either acupuncture or moxibustion can relieve the symptoms of IBS-D and protect intestinal mucosa, which may be associated with regulating the structure of intestinal flora and promoting nutrient metabolism and biosynthesis.

Abstract: Objective To explore the influencing factors of serum HBeAg loss in patients with chronic hepatitis B (CHB) and and provide evidence for effective treatment of CHB. Methods A follow-up cohort of HBeAg-positive CHB patients was established in the the Infectious Diseases Outpatient Clinic of hospital. Regular follow-up and laboratory test indicators were collected to analyze the changes of serum HBeAg in HBeAg-positive CHB patients during the follow-up period. The subjects were divided into the case group (serum HBeAg loss) and the control group (serum HBeAg not loss) according to whether serum HBeAg loss occurred. The baseline data characteristics of the two groups were analyzed and compared, and the influencing factors of serum HBeAg loss were analyzed by Cox univariate and multivariate regression. Results A total of 634 HBeAg-positive CHB patients were enrolled, with a total follow-up of 2 570.01 person-years. Among them, 237 cases of serum HBeAg loss occurred, with the mean follow-up time of 40.92 months, and the rate of HBeAg loss was 9.22/100 person-years. There were significant differences in HBV family history, antiviral therapy, baseline WBC, PLT, ALT, AST, T˗Bil, GGT, AFP, quantitative HBsAg and quantitative HBeAg between serum HBeAg loss group and serum HBeAg not loss group (P<0.05). Cox regression analysis showed that family history of HBV (HR 0.68, 95％CI:0.50-0.92, P=0.012), ALT (HR2.06, 95％CI:1.52-2.79, P<0.001), quantitative HBsAg (HR 0.68, 95％CI:0.48-0.95, P=0.024), quantitative HBeAg (HR 0.48, 95％CI:0.31-0.74, P=0.001) were independent influencing factors for HBeAg loss in HBeAg-positive CHB patients. Conclusions HBeAg-positive CHB patients without family history of HBV, initial ALT≥80 U/L, quantitative HBsAg<1 000 IU/ml, quantitative HBeAg<1 000 C.O.I are more likely to have serum HBeAg loss.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

As arsenic widely exists in nature and has been used in the pharmaceutical preparations, the traditional Chinese medicine(TCM) with arsenic include realgar(As_2S_2 or As_4S_4), orpiment(As_2S_3), and white arsenic(As_2O_3). Among the above representative medicine, the TCM compound formulas with realgar are utilized extensively. Just in Chinese Pharmacopoeia(2020 edition), there are 37 Chinese patent medicines including realgar. The traditional element analysis focuses on the detection of the total amount of elements, which neglects the study on the speciation and valence of elements. The activity, toxicity, bioavailability, and metabolic pathways of arsenic in vivo are closely related to the existence of its form, and different forms of arsenic have different effects on organisms. Therefore, the study on the speciation and valence of arsenic is of great importance for arsenic-containing TCMs and their compound formulas. This paper reviewed four aspects of the speciation and valence of arsenic, including property, absorption and metabolism, toxicity, and analytical assay.

For wild natural medicine, unanticipated biodiversity as species or varieties with similar morphological characteristics and sympatric distribution may co-exist in a single batch of medical materials, which affects the efficacy and safety of clinical medication. DNA barcoding as an effective species identification tool is limited by its low sample throughput nature. In this study, combining DNA mini-barcode, DNA metabarcoding and species delimitation method, a novel biological sources consistency evaluation strategy was proposed, and high level of interspecific and intraspecific variations were observed and validated among 5376 Amynthas samples from 19 sampling points regarded as "Guang Dilong" and 25 batches of proprietary Chinese medicines. Besides Amynthas aspergillum as the authentic source, 8 other Molecular Operational Taxonomic Units (MOTUs) were elucidated. Significantly, even the subgroups within A. aspergillum revealed here differ significantly on chemical compositions and biological activity. Fortunately, this biodiversity could be controlled when the collection was limited to designated areas, as proved by 2796 "decoction pieces" samples. This batch biological identification method should be introduced as a novel concept regarding natural medicine quality control, and to offer guidelines for in-situ conservation and breeding bases construction of wild natural medicine.
