AIM To investigate the effects of Xuesaitong Capsules(Panax notoginseng saponins)on ischemia/reperfusion injury in a mouse model of skin frostbite.METHODS The mice were randomly divided into the control group,the model group,the dexamethasone group(1 mg/kg),and the low-dose,medium-dose,and high-dose Xuesaitong Capsules groups(0.036,0.072,and 0.144 g/kg),with eight mice in each group.A frostbite model was established using a dry ice-cooled ceramic(ferrite)magnet.On the 2nd day after modeling,each group started its corresponding dosing by gavage for 14 consecutive days.The wound healing,histopathological changes,and serum levels of high-sensitivity C-reactive protein(hs-CRP),thromboxane B2(TXB2),6-keto-prostaglandin F1α(6-K-PGF1α),nitric oxide(NO)and endothelin(ET)were assessed using ELISA.The superoxide dismutase(SOD)activity and malondialdehyde(MDA)levels in skin tissues were measured biochemically.The protein expressions of tumor necrosis factor(TNF)-α,interleukin(IL)-1β,IL-6,Toll-like receptor(TLR)4 and phosphorylated nuclear factor-KB p65(p-NF-κB p65)in skin tissues were determined by Western blot.Additionally,LncRNA H19 mRNA expression in skin tissues was evaluated using RT-qPCR.RESULTS After the final administration,compared with the control group,the model group exhibited partial scab detachment,wound healing,and larger wound areas;hyperkeratosis with incomplete keratinization,detachment of the dermis and subcutaneous tissue,partial loss of appendages,subcutaneous edema,and dilated,congested,and hemorrhagic stromal vessels with extensive lymphocyte infiltration revealed by the histopathological examination;elevated serum levels of hs-CRP,TXB2,and ET(P＜0.05,P＜0.01);decreased 6-K-PGF1α and NO levels(P＜0.05,P＜0.01);reduced SOD activity in skin tissues(P＜0.01);increased MDA levels(P＜0.01);and upregulated protein expressions of TNF-α,IL-1β,IL-6,TLR4 and p-NF-κB p65,as well as LncRNA H19 mRNA expression(P＜0.05,P＜0.01).Compared with the model group,the group intervened with high-dose Xuesaitong Capsules displayed reduced wound areas(P＜0.01);decreased serum levels of hs-CRP,TXB2 and ET(P＜0.05,P＜0.01);increased 6-K-PGF1α and NO levels(P＜0.05,P＜0.01);enhanced SOD activity(P＜0.05,P＜0.01);reduced MDA level in skin tissues(P＜0.05,P＜0.01);and down-regulated TNF-α,IL-1β,IL-6,TLR4 and p-NF-κB p65 protein expressions and suppressed LncRNA H19 mRNA expression in skin tissues as well(P＜0.05,P＜0.01).CONCLUSION Xuesaitong Capsules alleviate ischemia/reperfusion injury in frostbite-injured mice by exerting anti-inflammatory and anti oxidative stress effects and restoring vascular endothelial function mediated by the downregulation of LncRNA H19 expression and inhibition of the TLR4/NF-κB signaling pathway.

Objective To investigate the peripheral blood cytokine levels in patients with acute myocardial infarction(AMI),and to analyze its correlation with Killip classification,N-terminal brain natriuretic peptide precursor(NT-proBNP),cardiac troponin I(cTnI),creatine kinase isoenzymes(CK-MB),and to provide a theoretical basis for assessing the severity and prognosis of the disease.Methods A total of 312 patients with AMI admitted to Minhang Hospital,Fudan University from Jul 2021 to Oct 2023 were enrolled as the case group,and 201 patients with unstable angina pectoris were selected as the control group.General clinical data of the subjects were collected,and the concentrations of cytokines(IL-5,IFN-α,IFN-γ,IL-10,IL-12p70,IL-17,IL-1β,IL-2,IL-4,IL-6,IL-8,and TNF-α)in peripheral blood were detected by multiplex bead-based flow cytometry.NT-proBNP,cTnI and CK-MB were measured by chemiluminescence methods.The levels of cytokines between the two groups were compared,and their correlations with Killip classification,NT-proBNP,cTnI and CK-MB were analyzed.The predictive efficacy of cytokines for AMI was evaluated by receiver operating characteristic(ROC)curves.Results There were no significant differences in baseline data between the AMI group and the control group(P>0.05),with the exception of age.The levels of IL-6,IL-8 and TNF-α in the AMI group were higher than those in the control group(all P<0.01).The correlation analyses showed that IL-6 was positively correlated with Killip classification,NT-proBNP,cTnI and CK-MB(all P<0.01).ROC analyses showed that IL-6 levels had good predictive efficacy for AMI(AUC=0.882 9,P<0.01).Conclusion The expression of IL-6 was significantly increased in patients with AMI,and it was positively correlated with Killip classification,NT-proBNP,cTnI and CK-MB,suggesting that IL-6 may serve as a potential biomarker for assessing the severity of AMI.

Objective:To explore the risk factors and etiological characteristics of urinary tract infection caused by urinary calculi in eastern Fujian region,in order to attract clinical attention and improve the prevention and treatment of urinary tract infection caused by urinary calculi.Methods:A total of 154 patients with urinary calculi admitted to Ningde People's Hospital(n=80)and Ningde Mindong Hospital(n=74)from November 2022 to October 2023 were selected as the main research objects.According to whether the patients had urinary tract infection,they were divided into infection group and non-infection group.The baseline data of the two groups were analyzed in detail,and the risk factors and pathogen distribution of urinary tract infection in patients with urinary calculi were analyzed.Results:There were 33 cases of urinary tract infection in 154 patients with urinary calculi,accounting for 21.43％.Univariate analysis showed that the urinary white blood cell count in the infection group was higher than that in the non-infection group,and the proportion of patients with effusion,urinary tract obstruction,calculi in the upper urinary tract,staghorn calculi,smoking history,diabetes,and urinary nitrite positive was higher than that in the uninfected group(P＜0.05).The results of binary logistic regression analysis showed that effusion,urinary tract obstruction,staghorn calculi,smoking history,diabetes,high urine white blood cell count and positive urine nitrite were independent risk factors for urinary tract infection in patients with urinary calculi(OR＞1,P＜0.05).A total of 33 strains of pathogenic bacteria were isolated from 33 patients in the infection group.Among them,23 strains(69.70％)were gram-negative bacteria,8 strains(24.24％)were gram-positive bacteria,and 2 strains(6.06％)were fungi.Among gram-negative bacteria,escherichia coli accounted for the highest proportion(48.48％),followed by klebsiella pneumoniae(9.09％).Among gram-positive bacteria,enterococcus faecalis accounted for the highest proportion(12.12％),followed by enterococcus faecium(6.06％).Candida and candida tropicalis in fungi was the same,accounted for 3.03％.Conclusion:The risk of urinary tract infection in patients with urinary calculi in eastern Fujian region is high.Effusion,urinary tract obstruction,staghorn calculi,smoking history,diabetes,high urine white blood cell count and positive urine nitrite are independent risk factors for urinary tract infection in patients with urinary calculi.The main urinary tract pathogens are gram-negative bacteria.

Objective This study aims to investigate the epidemiological characteristics of mental disorders in a rural town of Huazhou City,Guangdong Province,and explore their association with the rural revitalization strategy,so as to provide evidence for policy formulation.Methods A combination of questionnaire surveys and in-depth interviews was used to collect in-formation on the demographic characteristics,disease status,economic conditions,and policy awareness of registered mental dis-order patients in the town.Semi-structured interviews were also conducted with local doctors and village committee members.Da-ta were analyzed using descriptive statistics and logistic regression models to assess the impact of awareness of rural revitalization policies on patients'income.Results The average age of the study subjects was 47.71 years,with an average disease duration of 18.38 years.A total of 86.36％of patients had a family history of mental disorders.After onset,42.11％of patients had an annual income≥￥ 10 000,which was an increase compared to pre-illness levels,but 60.75％had completely lost their ability to work.Awareness of rural revitalization policies was low(only 18.29％were fully aware),but policy awareness was significant-ly associated with increased patient income(OR=18.03,P＜0.001).Additionally,medical expenditures were significantly higher among female patients than male patients(P＜0.001).Conclusion In a town in Huazhou City,Guangdong Province,60.75％of mental disorder patients have completely lost their ability to work,while 42.11％have an annual income exceeding ￥ 10,000.Income is positively correlated with policy awareness(OR=18.03).It is recommended to strengthen policy promo-tion,optimize the allocation of medical resources,and develop specialized assistance programs to promote the coordinated devel-opment of mental health and rural revitalization.

Objective To explore the performance of gallium nitride(GaN)-based digital circuit chips applied in nuclear radiation environments and investigate the feasibility of their use in control chips for robots transporting injured personnel.Methods First,a GaN-based NAND gate digital circuit chip was fabricated.Second,both the GaN-based digital chip and the SN74AHCT1G00 silicon-based digital chip were irradiated with 60Co gamma-ray.The irradiation doses for the GaN-based digital chip were 1 Mrad(Si)and 2 Mrad(Si),while the irradiation dose for the SN74AHCT1G00 silicon-based digital chip was 1 Mrad(Si).Finally,the post-irradiation electrical performance of the two chips was measured using a Keithley 4200A-SCS semiconductor characterization system.Results Under 60Co gamma-ray irradiation doses of 1 Mrad(Si)and 2 Mrad(Si),the response delay of the GaN-based digital circuit chip was only on the order of 0.1 μs.In contrast,the response rate of the SN74AHCT1G00 silicon-based digital circuit chip significantly degraded under 60Co gamma-ray irradiation dose of 1 Mrad(Si),rendering it unable to perform the NAND gate logic function.Conclusion GaN-based digital circuit chips exhibit high radiation resistance in 60Co gamma-ray irradiation environments,with no significant performance degradation.Compared with silicon-based digital circuit chips,they demonstrate considerable advantages and can preliminarily meet the requirements for control chips of robots transporting injured personnel in nuclear radiation environments.
