Aim To investigate the effects of puerarin on the proliferation,migration,and apoptosis of glio-blastoma cells and the underlying mechanisms.Meth-ods Differentially expressed genes associated with gli-oma and mitochondrial disease were analyzed using the GEO database.Cytotoxicity was detected by CCK-8 as-say.Cell migration was detected by the scratch wound healing assay and Transwell assay.Cell proliferation was assessed by EdU assay.Apoptosis level was meas-ured by TUNEL assay.Mitochondrial membrane poten-tial was detected by Mito-Tracker assay.ATP contents were detected using the ATP kit.The protein expres-sion levels were detected by Western blot.Antitumor efficacy of puerarin was analyzed using subcutaneous xenograft.Results There were 178 genes co-related differentially expressed genes in glioma and mitochon-drial disease.Core genes of co-related differentially ex-pressed genes were screened by GO and KEGG enrich-ment analyses,and the interaction networks.Among them,ubiquitin C(UBC)level was highly expressed in tissues of glioma patients.Puerarin could bind to UBC and reduce UBC expression at the animal and cell levels.Puerarin treatment inhibited the growth of glio-ma and decreased cell proliferation,migration and pro-moted cell apoptosis signals.Meantime,puerarin treat-ment also reduced mitochondrial membrane potentials and ATP contents,and down-regulated the levels of UBC related proteins.Conclusion Puerarin inhibits the proliferation,migration and promotes apoptosis of glioma cells.The mechanism of induction of mitochon-drial dysfunction is involved.

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:To investigate the neuroprotective effect of Danggui Shaoyaosan （DSS） in a rat model of amyloid-β-peptide_1-42 （Aβ_1-42）-induced Alzheimer's disease （AD） as well as its regulatory effect on NOD-like receptor protein 3 （NLRP3）/cysteinyl aspartate-specific protease-1 （Caspase-1） signaling pathway. Method:The AD animal model was established via intracerebral injection of Aβ_1-42 and treated with different concentrations of DSS after the division of rats into the sham operation group， model group， as well as the high-， medium-， and low-dose DSS groups. Morris water maze test was conducted to determine the learning and memory abilities of rats. The morphology and function of neurons were detected by hematoxylin-eosin （HE） staining and Golgi staining， followed by immunofluorescence co-localization of NLRP3 inflammasome activation. The mRNA expression levels of interleukin （IL）-1β and IL-18 were measured by Real-time polymerase chain reaction （Real-time PCR）， and the protein expression levels of NLRP3， Caspase-1， and IL-1β were assayed by Western blot. Result:Compared with the sham operation group， the model group exhibited significantly decreased learning and memory abilities （P<0.01）， impaired neuronal morphology and function， up-regulated IL-1β and IL-18 mRNA expression， enhanced NLRP3 inflammasome activation， and elevated NLRP3， Caspase-1， and IL-1β protein expression （P<0.01）. Compared with the model group， DSS at both medium and high doses remarkably improved the learning and memory abilities of AD rats （P<0.05， P<0.01）， restored neuronal morphology and function， down-regulated the mRNA expression levels of inflammatory factors IL-1β and IL-18， reduced the activation of NLRP3 inflammasomes， and lowered the protein expression levels of NLRP3， Caspase-1， and IL-1β （P<0.01）. Conclusion:DSS inhibits inflammasome activation and neuroinflammatory response possibly by regulating the NLRP3/Caspase-1 signaling pathway， thus exerting the neuroprotective effect.

Adult-onset Still's disease (AOSD) is a rare but clinically well-known, polygenic, and systemic autoinflammatory disease, which is characterized by spiking fever, evanescent skin rash, arthralgia, and sore throat. The application of non-steroidal anti-inflammatory drugs and glucocorticoids, which are first-line therapies of AOSD, is limited due to their side effects such as liver injury or disorder of blood glucose. Therefore, patients who suffer from systemic diseases in China prefer to seek help from Chinese herbal medicine (CHM), which is an important part of complementary and alternative medicine. In this case, we report a 28-year-old male badminton coach presenting with a 15-day history of fever and skin rash, accompanied by sore throat, fatigue, myalgia and chills. Additionally, hepatosplenomegaly, multiple lymphadenopathies, aminotransferase abnormality, and elevated inflammatory factor levels were observed during hospitalization. Infectious diseases, solid tumors, hematological diseases, and common autoimmune diseases were excluded. Not benefitting from antibiotic therapy, the patient was finally diagnosed with AOSD, after a careful examination, then showed rapid remission after a six-week treatment with CHM granules based on Xiaochaihu Decoction and Yinqiao Powder. After stopping the treatment, there was no relapse within a 15-month follow-up period. To the best of our knowledge, this is the first well-documented case of this successful treatment. The present case report suggests that CHM is a reliable choice for complementary and alternative therapy for AOSD, but confirming the utility of CHM for AOSD requires further support from prospective studies.

OBJECTIVETo study the effect of golden-hour body temperature bundle management strategy on admission temperature and clinical outcome in preterm infants with a gestational age of <34 weeks after birth.

METHODSThe preterm infants who were born in the delivery room of the West China Second University Hospital of Sichuan University and admitted to the department of neonatology of this hospital within 1 hour after birth from December 2015 to June 2016 and from January to May, 2017 were enrolled. The 173 preterm infants who were admitted from January to May, 2017 were enrolled as the intervention group and were given golden-hour body temperature bundle management. The 164 preterm infants who were admitted from December 2015 to June 2016 were enrolled as the control group and were given conventional body temperature management.

RESULTSThe intervention group had a significantly higher mean admission temperature than the control group (36.4±0.4°C vs 35.3±0.6°C; P<0.001). The incidence rate of hypothermia on admission in the intervention group was significantly lower than that in the control group (56.6% vs 97.6%; P<0.001). The intervention group had a significantly lower incidence rate of intracranial hemorrhage within one week after admission than the control group (15.0% vs 31.7%; P<0.05).

CONCLUSIONSGolden-hour body temperature bundle management for preterm infants within one hour after birth can reduce the incidence of hypothermia on admission and improve clinical outcome.

OBJECTIVE To explore the anti-atherosclerotic effect of the extract of traditional Chinese medicine formula Dan-yi-lian(DYL)and the related mechanism.METHODS Atherosclerosis(AS)mod-el was established in ApoE(-/-)mice with a western diet. The mice were orally administered with differ-ent doses of DYL or vehicle daily for 28 d.The anti-atherosclerotic effect was evaluated by measuring the aortic atherosclerotic lesion area and media thickness with ultrasound imaging and histological sec-tions staining method. The effect on blood lipid was investigated by determining TC, TG, LDL, HDL, Apo-A1, Apo-B, etc. The anti-oxidative activity as assessed by determining the level of SOD, CAT, GSH,GSH-Px and MDA.Western blot analysis was used to determine the effect on ICAM-1,VCAM-1, MMP-2 and TNF-α. RESULTS In Dan-yi-lian administered ApoE(-/-)mice,the plaque area and media thickness were significantly reduced. Meanwhile, serum TC, TG, LDL and Apo-B were decreased, in contrast to the increased level of HDL and Apo-A1.On the other hand,SOD,CAT,GSH and GSH-Px were increased, while MDA was reduced in liver homogenate. In addition, the expression of ICAM-1, VCAM-1,MMP-2 and TNF-α was obviously inhibited by Dan-yi-lian.CONCLUSION Dan-yi-lian exhibit-ed potent anti-athero-sclerotic efficacy,in which the lipid-regulating,anti-oxidative and anti-inflammato-ry mechanism might be involved.

Objective To study the correlation between the deformation and displacement trend of the lumbosacral vertebra (L1-S1) for two typical scoliosis spines under vertical loads,so as to provide the mechanical basis of treatment and prevention of scoliosis in clinic.Methods The X-ray computed tomography (CT) images of two typical scoliosis spines (Lenke-4AN type and Lenke-5CN type) were converted into 3D models,and their finite element models were then established and verified.The internal stress distribution and displacement variation of the models were calculated by the finite element software;the correlation between the lumbosacral vertebral structure and displacement of the spine was analyzed.Results Under the same boundary conditions and load cases,the stress and displacement for two kinds of lumbosacral vertebral models showed different trends.Due to its leftleaning and forward convex bending deformation as well as the relatively large lordosis angle (60°) and smaller left-leaning angle (17.37°),the Lenke-4AN type lumbosacral spine produced slightly small forward convex displacement (8.18 mm) and relatively large left-leaning displacement (0.97 mm).The Lenke-5CN type lumbosacral spine showed left-leaning and forward convex bending deformation as well,with relatively large lordosis angle(59°) and left-leaning angle (26.97°),so it produced more severe left-leaning displacement (20.65 mm) andforward convex displacement (9.22 mm).Conclusions The deformation trend of lumbosacral vertebra is closelyrelated to its structural characteristics,and different scoliosis lumbosacral vertebral structures will cause the corre-sponding deformation trend.The research findings are important for the prevention and treatment of scoliosis.

BACKGROUNDThis study aimed to evaluate the effects of standard rescue procedure (SRP) in improving severe trauma treatments in China.

METHODSThis study was conducted in 12 hospitals located in geographically and industrially different cities in China. A standard procedure on severe trauma rescue was established as a general rule for staff training and patient treatment. A regional network (system) efficiently integrating prehospital rescue, emergency room treatments, and hospital specialist treatments was built under the rule for information sharing and improving severe trauma treatments. Treatment outcomes were compared between before and 1 year after the implementation of the SRP.

RESULTSThe outcomes of a total of 74,615 and 12,051 trauma cases were collected from 12 hospitals before and after the implementation of the SRP. Implementation of the SRP led to efficient cooperation and information sharing of different treatment services. The emergency response time, prehospital transit time, emergency rescue time, consultation call time, and mortality rate of patients were 24.24 ± 4.32 min, 45.69 ± 3.89 min, 6.38 ± 1.05 min, 17.53 ± 0.72 min, and 33.82% ± 3.87% (n = 441), respectively, before the implementation of the standardization and significantly reduced to 10.11 ± 3.21 min, 22.39 ± 4.32 min, 3.26 ± 0.89 min, 3.45 ± 0.45 min, and 20.49% ± 3.11%, separately (n = 495, P < 0.05) after that.

CONCLUSIONSStaff training and SRP can significantly improve the efficiency of severe trauma treatments in China.
