ObjectiveTo investigate the therapeutic effects and mechanism of Shenqi Dihuang decoction （SQDHD） on diabetic kidney disease （DKD）， with a focus on its impact on arachidonic acid-related ferroptosis. MethodsSixty C57BL/6 mice were allocated into a normal group （n=10） and a modeling group （n=50）， with 43 mice successfully modeled. The successfully modeled mice were further allocated into model， low-， medium-， and high-dose （4.68， 9.36， and 18.72 g·kg^-1， respectively） SQDHD， and dapagliflozin （0.13 mg·kg^-1） groups. The drug treatment groups were administrated with corresponding agents by gavage， and the normal and model groups were administrated with equal volumes of normal saline by gavage. An electronic balance and a glucometer were used to monitor the body weight and fasting blood glucose level from the tail tip， respectively. Serum creatinine （Scr） and blood urea nitrogen （BUN） levels were measured by enzyme-linked immunosorbent assay （ELISA）. Histopathological changes in the renal tissue were assessed by hematoxylin-eosin staining， Masson staining， and periodic acid-Schiff （PAS） staining. The fluorescence intensity of reactive oxygen species （ROS） in frozen sections was observed by an inverted fluorescence microscope to evaluate the levels of ferrous ions （Fe²⁺） and lipid peroxidation in the renal tissue. Immunofluorescence staining of glutathione peroxidase 4 （GPX4） and acyl-CoA synthetase long-chain family member 4 （ACSL4） in the renal tissue was performed to detect their localization and expression. Western blot was employed to assess the expression levels of key ferroptosis proteins such as GPX4 and cystine/glutamate antiporter （xCT）， as well as the arachidonic acid metabolic pathway-related proteins， including ACSL4， lysophosphatidylcholine acyltransferase 3 （LPCAT3）， and arachidonate 15-lipoxygenase （ALOX15）. Real-time PCR was employed to measure the mRNA levels of key ferroptosis proteins， including solute carrier family 7 member 11 （SLC7A11） and GPX4， as well as arachidonic acid metabolism-related factors （ACSL4， LPCAT3， and ALOX15） in the renal tissue. ResultsCompared with the normal group， DKD model mice exhibited a decrease in body weight （P<0.01）， increases in levels of blood glucose （P<0.01）， 24-hour urinary protein， Scr， and BUN （P<0.01）， along with severe pathological changes， such as mesangial cell proliferation， basement membrane thickening， tubular atrophy， and interstitial inflammatory cell infiltration. In addition， the modeling elevated the levels of Fe²⁺， MDA， LPO， and ROS （P<0.01）， lowered the GPX4 and xCT levels （P<0.01）， raised the ACSL4， LPCAT3， and ALOX15 levels （P<0.01）， down-regulated the mRNA levels of GPX4 and SLC7A11 （P<0.01）， and up-regulated the mRNA levels of ACSL4， LPCAT3， and ALOX15 （P<0.01） in the renal tissue. Compared with the model group， low-， medium-， and high-dose SQDHD groups and the dapagliflozin group showed an increase in body weight （P<0.01）， decreases in levels of blood glucose （P<0.01）， 24-hour urinary protein， and Scr （P<0.01）， alleviated pathological changes in glomeruli and tubules， and reduced degree of glomerular and tubular fibrosis. The high-dose SQDHD group and the dapagliflozin group showed reductions in Fe²⁺， MDA， LPO， and ROS levels （P<0.01）. The medium- and high-dose SQDHD groups and the dapagliflozin group exhibited increased levels of GPX4 and xCT （P<0.01）， decreased levels of ACSL4， LPCAT3， and ALOX15 （P<0.05， P<0.01）， and down-regulated mRNA levels of ACSL4， LPCAT3， and ALOX15 （P<0.01）. ConclusionSQDHD ameliorates DKD by inhibiting ferroptosis potentially by reducing iron ion levels， inhibiting lipid peroxidation， up-regulating GPX4 expression， and down-regulating ACSL4 expression. This study provides new insights and a theoretical basis for the treatment of DKD with traditional Chinese medicine and identifies potential targets for developing novel therapeutics for DKD.

Objective:To investigate the distribution rules of artemisia pollen and the clinical sensitization characteristics of allergic rhinitis (AR) induced by artemisia pollen in three urban and rural areas of Inner Mongolia.Methods:From March to October 2019, in 3 central cities (Chifeng, Hohhot, Ordos) and rural areas of Inner Mongolia, an epidemiological investigation method combining multi-stage stratified random sampling and face-to-face questionnaire survey was adopted to screen suspected AR patients, and skin prick test (SPT) was applied for diagnosis. At the same time, pollen monitoring was carried out in 3 areas to analyze the distribution and clinical sensitization characteristics of artemisia pollen.SPSS26.0 statistical software was used to process all the data. Chi-square test was used to compare rates among different age, sex, region and nationality, Spearman test was used to describe correlation analysis, and pairwise comparison of positive rates among multiple samples was used Bonferroni method.Results:Among the 6 393 subjects, 1 093 cases were diagnosed with AR, and the prevalence of AR was 17.10% (1 093/6 393). Among them, pollen-induced allergic rhinitis, the prevalence of PiAR was 10.97% (701/6 393), accounting for 64.14%(701/1 093).The highest incidence was in the youth group (20-39 years old), accounting for 46.94% (329/701).The diagnosed prevalence was higher in females than in males (11.35% vs. 10.64%, χ2 value 12.304, P<0.001).The prevalence rate of ethnic minority was higher than that of Han nationality (13.01% vs. 10.65%, χ2 value 6.296, P=0.008).The prevalence in urban areas was also significantly higher than that in rural areas (18.40% vs. 5.50%, χ2 value 10.497, P<0.001).There was significant difference in prevalence rate among the three regions in Inner Mongolia (6.06% in Chifeng, 13.46% in Hohhot, 16.39% in Ordos, χ2 value 70.054, P<0.001).The main clinical symptoms of artemisia PiAR were sneezing (95.58%), nasal congestion (91.73%) and nasal itching (89.30%).Allergic conjunctivitis accounted for 79.60% (558/701), chronic sinusitis for 55.63% (390/701), asthma for 23.25% (163/701).The pattern of artemisia pollen sensitization was mainly multiple sensitization, and the frequency of clinical symptoms and clinical diseases induced by hypersensitization with other allergens accounted for more than that caused by single artemisia pollen. The spread period of Artemisia pollen in the three regions was from June to October, and the peak state was in August in summer. The peak time of clinical symptoms in artemisia PiAR patients was about 2 weeks earlier than the peak time of pollen concentration, and the two were significantly positively correlated ( R=0.7671, P<0.001). Conclusion:Artemisia pollens are the dominant pollens in late summer and early autumn in Inner Mongolia, and the prevalence of artemisia PiAR is high. Controlling the spread of Artemisia pollens is of great significance for the prevention and treatment of AR.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the effects of Aikeqing(AKQ),a compound of Chinese medicine,on drug-metabolizing activity and on the pharmacokinetic parameters of HIV-1 protease inhibitors lopinavir(LPV)and ritonavir(RTV)in Kaletra tablets.Methods Human liver microsomes were co-incubated with mixed probes and AKQ.HPLC-MS was employed to measure the content of probe.Half-inhibitory concentration(IC50)of AKQ on different subtypes of cytochrome P450 enzymes involved in drug metabolism of liver microsomes was calculated.The P450 subtype,whose activity was significantly inhibited by AKQ was then identified.HPLC-MS analytical method for simultaneous determination of LPV and RTV in rat plasma was established.SD rats were orally given AKQ or vehicle once a day for 7 consecutive days.After half an hour of the last gavage of AKQ,the rats were given Kaletra by intragastric administration.Then,the blood concentration of LPV and RTV were measured and the effect of AKQ on pharmacokinetic parameters of LPV and RTV were analyzed.Results The methanol extract of AKQ at the concentrations of 0～500 μg·mL-1 showed inhibitory effects on the metabolic activity of CYP2D6,CYP2C8、CYP2E1,CYP2C19,CYP1A2,CYP2B6,CYP2C9 and CYP3A4,with IC50 values of 7.7,75.3,144.0,99.5,43.5,104.5,49.3 and 204.9 μg·mL-1,respectively.An HPLC-MS/MS method was established for simultaneous quantification of LPV and RTV in blood samples.LPV and RTV showed linear relationships in the ranges of 30～10 000 ng·mL-1 and 3～1 000 ng·mL-1,respectively.The lowest limits of quantification were 30 ng·mL-1 and 3 ng·mL-1.Intra-day and inter-day precision were all less than 5%,and the accuracy of LPV and RTV was in the range of 96.3%～109%.The extraction recovery rates were not less than 88.7%,the matrix effects were 93.8%～105.0%,and the plasma samples were stable.Compared with Kaletra group,there was no significant changes in non-compartmental model parameters including AUC0-t,AUC0-∞,MRT0-t,t1/2z,tmax,Vz/F,Clz/F and Cmax of LPV in AKQ+Kaletra group(P＞0.05).But MRT0-∞ was found to be obviously affected by AKQ(P＜0.05).All pharmacokinetic parameters of RTV showed no significant change in AKQ+Kaletra group(P＞0.05).Conclusion Aikeqing exhibited varying degrees of inhibitory effects on 8 human drug-metabolizing cytochromes P450,especially CYP2D6.A human-equivalent dose of Aikeqing does not affect the pharmacokinetic parameters of lopinavir and ritonavir in rats.

Objective:To investigate the correlation between different degrees of white matter hyperintensities (WMHs) and outcome after intravenous thrombolysis (IVT) in patients with acute ischemic stroke.Methods:Patients with AIS received intravenous thrombolytic therapy with standard dose of alteplase in the First Hospital of Putian City from January 2019 to June 2022 were retrospectively included. The Fazekas scale was used to score the WMHs shown on MRI, and the patients were divided into without or mild WMH group and moderate-to-severe WMH group. The clinical baseline data and the clinical outcome after 3 months of the two groups were compared. The poor outcome was defined as the modified Rankin scale score >2. Multivariate logistic regression analysis was used to determine the influence of the severity of WMHs on the outcome after intravenous thrombolysis. Results:A total of 103 patients with AIS were included. Their age was 64.85±10.89 years old, and 66 (64.1%) were men. There were 60 patients (58.3%) in the without or mild WMH group, and 43 (41.7%) in the moderate-to-severe WMH group. There were significant differences in age, body mass index, systolic blood pressure, baseline National Institutes of Health Stroke Scale (NIHSS) scores, as well as the proportion of patients with hypertension, smoking, hemorrhagic transformation and poor functional outcome at 3 months after onset in different degrees of WMH groups (all P<0.05). There were 73 patients (70.9%) in the good outcome group and 30 (29.1%) in the poor outcome group. There were significant differences in age, body mass index, baseline NIHSS score, WMH score, as well as the proportion of patients with hypertension, large atherosclerotic stroke and symptomatic intracranial hemorrhage between the two groups ( P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors, moderate-to-severe WMHs were the independent risk factors for the poor outcome at 3 months after intravenous thrombolysis (odds ratio 3.810, 95% confidence interval 1.298-1.124; P=0.015). Conclusion:Moderate-to-severe WMHs are associated with the poor outcome in patients with AIS at 3 months after intravenous thrombolysis.

Objective To investigate whether the characteristics of pathogens mediated by Wolbachia can interfere with Japanese encephalitis virus (JEV) replication and explore the regulatory role of Wolbachia on JEV replication transmitted by Culex mosquitoes. Methods Real-time fluorescence quantitative PCR (qPCR) and RNA fluorescence in situ hybridization (RNA-FISH) were used to detect Wolbachia density in Aa23 (naturally infected with Wolbachia) Aedes albopictus cell and negative control Aa23T Aedes albopictus cells (Wolbachia infection was removed by tetracycline treatment). The plaque assay was conducted to measure the viral titers and cytopathic effect (CPE) in Aa23T and Aa23 cells on days 1 to 8 after JEV (P3 strain) infection. Results qPCR and RNA-FISH results consistently showed that the symbiosis of Wolbachia was negative in Aa23T cell. In Aa23 cells, the copy number of the WSP gene of Wolbachia and the fluorescence signal intensity targeting Wolbachia 16S rDNA increased with cell growth time. In response to JEV infection, Wolbachia prolonged the CPE in viral infected Aa23 cells, which compared to infected Aa23T cells. The plaque assay result has obviously showed that JEV titer in Aa23 cells (106 PFU/mL) was significantly lower than that in Aa23T control cells (108 PFU/mL). Conclusions Wolbachia significantly delays CPE of JEV on cells and inhibits JEV replication in A. albopictus cells. To the best of our knowledge, this is the first report that Wolbachia strongly inhibits JEV infection in mosquito cells. It revealed the role of Wolbachia on inhibition of the viruses that transmitted by Culex mosquitoes. In particular, it provides important experimental data and theoretical basis for application of Wolbachia-based mosquito control technology in prevention and control of JEV.

Objective:To study the epidemiological characteristics and pathogen status of infection of patients with herpetic pharyngitis in eastern region of Chengdu in 2022, in order to provide experimental basis for scientific prevention and control of herpetic pharyngitis.Methods:Information and fecal specimens were collected from patients diagnosed with herpetic angina at sentinel monitoring hospitals in eastern region of Chengdu from January to December 2022, their epidemiological characteristics were analyzed, real-time fluorescence quantitative PCR (RT-PCR) and semi nested RT-PCR (RT-snPCR) were used to detect and identify enterovirus subtypes.Results:Among the 236 cases of herpetic angina, the age of the affected children was mainly 0-9 years (99.15%), with children aged below 3 years accounting for 75.85% of the total cases, children in the 1-year-old group had the highest constituent ratio, accounting for 47.88% of the total cases; The virus detection rate in the 2-year-old group was higher than that in the 0-year-old group ( χ2=5.945, P=0.015). There were 142 male infected cases (60.17%) and 94 female cases (39.83%); there was a statistically significant difference in the virus detection rate between the male group (91.55%) and the female group (78.72%) ( χ2=7.938, P=0.005). In the seasonal distribution, the summer group had the highest constituent ratio (40.25%), while the winter group had the lowest constituent ratio (11.86%), The composition ratio of the summer group was significantly higher than that of the other groups, and the differences were statistically significant ( χ2=10.393, 19.199, 49.358, all P<0.001). The virus detection rate in the summer group was significantly higher than that in the spring group and the winter group ( χ2=16.951, 4.592, both P<0.05). The RT-PCR result showed that a total of 204 out of 236 children with herpetic angina were virus positive, with a detection rate of 86.44% (204/236), including coxsackievirus A (CV-A) 6 (22.55%), CV-A16 (5.88%), CV-A2 (2.94%), enterovirus type A71 (EV-A71) (2.94%), and other enteroviruses (65.69%). The RT-snPCR result showed that five viruses were identified from other enteroviruses, including CV-A4 (8.33%), CV-A5 (6.86%), CV-A10 (12.25%), CV-A12 (24.02%), and coxsackievirus B3 (CV-B3) (6.86%); another 15 positive samples of enterovirus were not successfully classified. We selected 9 strains of the virus in this study and 30 reference sequences from the NCBI database to. Conclusions:Herpetic angina in eastern region of Chengdu in 2022 is mainly found in male children under 3 years of age, and was concentrated between April and June. It has been confirmed that CV-A12 and CV-A6 were more common in intestinal viruses, and the 9 strains isolated in this study were homologous to multiple isolates.

Objective:To evaluate the adjuvant role of the eCura scoring system in selecting appropriate treatment strategies after non-curative endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) patients.Methods:The clinicopathological data of 110 EGC patients who underwent non-curative ESD at Fujian Provincial Hospital from January 2015 to June 2019 were retrospectively analyzed. According to the eCura score, patients were divided into three lymph node metastasis (LNM) risk groups: low-risk group (79 cases), middle-risk group (22 cases), and high-risk group (9 cases). The receiver operator characteristic (ROC) curve analysis was used to test the diagnostic efficacy of eCura scoring system in predicting LNM. Logistic regression analysis was used to explore the influence of risk stratification of eCura scoring system on LNM. Kaplan-Meier method was used to evaluate cancer survival rate, which was then compared with log-rank test.Results:Thirty-five patients underwent additional standard surgery after ESD, including 22 in the low-risk group, 8 in the middle-risk group, and 5 in the high-risk group. Among them, 5 cases had LNM, including 1 case in the low-risk group and the middle-risk group respectively and 3 cases in the high-risk group. The area under the ROC curve was 0.857 (95% CI: 0.697-0.952, P=0.001), and when the cut-off value of the eCura score was set at 3, the Yuden index reached the maximum value of 0.7, with the corresponding sensitivity and specificity of 80% and 90%, respectively. Logistic regression analysis showed that the probability of LNM in the middle-risk group was about 3.00 times (95% CI: 0.17-54.57, P=0.458) as high as that in the low-risk group, and the probability of LNM in the high-risk group was about 31.50 times (95% CI: 2.14-463.14, P=0.012) of that in the low-risk group. The follow-up time was 12 to 58 months, and the median follow-up time was 40 months. There were 10 cases of recurrence, including 4 cases in the low-risk group, 3 cases in the middle-risk group and 3 cases in the high-risk group, of which 2 cases in the low-risk group were from those of additional standard surgery after ESD, and the remaining 8 cases were from those who did not receive additional standard surgery after ESD. Kaplan-Meier survival curve analysis showed that the survival rate of patients with additional surgery in the low-risk group was similar to that of patients without ( P=0.319), and the survival rate of patients with additional surgery in the middle-risk group was also similar to that of patients without ( P=0.296). The survival rate of patients with additional surgery in the high-risk group was significantly higher than that of those without ( P=0.013). Conclusion:The eCura scoring system can assist the selection of treatment strategies after non-curative resection of EGC, and can accurately predict the risk of subsequent LNM and recurrence. Close follow-up may be an acceptable option for patients with low risk of LNM, and additional standard surgical treatment may be more conducive to improving the prognosis in patients with high risk of LNM.
