Objective To analyze the influenza-like illness (ILI) data in Ordos City from 2017 to 2023 and conduct nucleic acid detection of the virus to understand the local influenza epidemic situation, and to provide a reliable basis for influenza prevention and control in the city. Methods Real-time quantitative polymerase chain reaction (qPCR) was used to identify virus subtypes in ILI throat swab samples. Comparisons of positive rates were conducted using the chi-square test, with a significance level of α=0.05. Results From 2017 to 2023, a total of 3,283,434 outpatient and emergency visits were recorded at the Ordos City Central Hospital, including 74,159 ILI cases, with an ILI proportion of 2.26%. The majority of ILI cases (74.43%) occurred in children aged 0~14 years old. The overall positive rate of influenza virus nucleic acid detection was 10.87%, with the highest proportion being subtype A (seasonal H3) at 43.03%. The highest detection rate was observed in the 5~14 years age group, with statistically significant differences in positive rates across age groups (χ²=155.638, P<0.001). Influenza peaks occurred mainly from November to March of the following year. From January to April, three types of influenza were prevalent alternately or mixed, while from October to December, subtype A (seasonal H3) predominated. Positive rates varied significantly across months (χ²=250.923, P<0.001). The temporal trends of ILI proportions and PCR-positive rates were consistent. Conclusion Influenza in Ordos City exhibits distinct seasonal and age distribution characteristics, with alternating or mixed circulation of three virus types. Continued efforts are needed to strengthen influenza surveillance, especially the prevention and control of influenza in infants and adolescents.

Objective:To explore the association between the use of tetracyclines during pregnancy and congenital malformations, with the aim of providing evidence-based guidance for the rational use of antibiotics during pregnancy.Methods:Data from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) and the Canada Vigilance Adverse Reaction (CVAR) database from January 2015 to September 2024 were collected. Five methods including Tree-based scan statistic (TreeScan), proportional reporting ratio (PRR), reporting odds ratio (ROR), the UK Medicines and Healthcare Products Regulatory Agency (MHRA) comprehensive standard, and the Bayesian confidence propagation neural network (BCPNN) were used to detect signals of risk for congenital malformations in offspring following maternal use of tetracyclines during pregnancy. A signal that met the threshold criteria of all above 5 methods was considered as a risk signal. Based on population-based cohort of the drug exposures and adverse pregnancy outcomes (DEEP) data from January 2013 to December 2021 in Xiamen City, propensity score matching (PSM)-based Poisson regression was applied to evaluate the association between the first-trimester tetracyclines exposure and congenital malformations in offspring. Adjusted relative risk (a RR) and its 95% confidence interval ( CI) were calculated. Sensitivity analysis was conducted to validate the reliability of the results. Results:A total of 304 098 reports of adverse events during pregnancy were obtained from the FAERS and CVAR databases. Among them, 5 028 reports were related to tetracyclines, including 1 026 reports of congenital malformations in offspring, involving congenital malformations of musculoskeletal system, other digestive system, and other congenital malformations. Signal detection results suggested that tetracyclines may be a risk signal for above congenital malformations in offspring. The DEEP data included 411 936 pregnant women. After PSM, 240 pregnant women exposed to tetracyclines were included. The results showed no significant association between the first-trimester tetracyclines exposure and congenital malformations in offspring (a RR=0.75, 95% CI: 0.26-2.17), sensitivity analysis also showed no correlation. Conclusions:Data mining from the FAERS and CVAR databases suggests a potential association between tetracyclines use during pregnancy and congenital malformations in offspring. However, the DEEP data study shows no significant correlation.

Aim To investigate the possible mechanism of the myocardial protective effect of Danzhi Jiangtang capsules(DJC)on db/db mice based on NLRP3 in-flammasome-mediated pyroptosis.Methods The db/db mice were randomly divided into the model group,DJC low,medium,and high dose groups,and the met-formin group,and the db/m mice were taken as the blank group.The administration lasted for eightweeks.At the end of drug administration,blood glucose,blood lipids,cardiac enzymes and inflammatory factors were detected in each group of mice.HE and Masson stai-ning was performed to observe the morphology and fi-brosis of myocardial tissue.TUNEL staining was per-formed to detect apoptosis.RT-qPCR was performed to detect the mRNA expression of ANP,BNP and β-MHC,and Western blot was performed to detect the protein expression of NLRP3,ASC,caspase-1,cleaved-caspase-1,GSDMD and GSDMD-NT in myocardial tis-sue.Results DJC could alleviate myocardial patho-logical damage,reduce collagen deposition and apopto-sis,reduce the levels of blood glucose,blood lipid,myo-cardial enzyme and inflammatory factors in db/db mice.DJC could reduce the mRNA expressions of ANP,BNP and β-MHC,and the protein expressions of NLRP3,ASC,caspase-1,cleavedcaspase-1,GSDMD and GSDMD-NT in myocardial tissues.Conclusion DJC attenuates myocardial injury in db/db mice,prob-ably by inhibiting the activation of NLRP3 inflamma-somes,attenuating cardiomyocyte pyroptosis,and amel-iorating the inflammatory state.

Objective:To evaluate the clinical efficacy and safety of an antioxidant gel containing tea polyphenols combined with narrow-band ultraviolet B in the treatment of vitiligo.Methods:A single-center, randomized controlled clinical trial was conducted. From April 25 to June 27, 2024, patients with vitiligo were selected from the Department of Dermatology, Hangzhou Third People's Hospital. An open-label and researcher-blinded design was used. The patients were divided into 3 groups: a phototherapy group receiving phototherapy alone, a tea polyphenols combined group treated with an antioxidant gel containing tea polyphenols combined with phototherapy, and a positive control group treated with an antioxidant gel containing superoxide dismutase combined with phototherapy, with the treatment duration being 3 months. The efficacy was evaluated using the Vitiligo Area Scoring Index (VASI), and when the VASI was improved by ≥ 10%, the treatment would be considered effective. Changes in skin aging and skin barrier function indicators before and after treatment were assessed for 72 vitiligo lesions in the tea polyphenols combined group and for 72 lesions in the phototherapy group. Comparisons between the groups were performed using one-way analysis of variance, Fisher's exact test, chi-square test, or t test. Results:A total of 171 vitiligo patients with 307 target lesions were successfully followed up in this study, including 74 males and 97 females, and their ages ranged from 1 to 64 years. Among the 307 lesions, 95 were treated with phototherapy alone, of which 35 showed improvement, resulting in a total response rate of 36.8% and an average VASI improvement rate of 10.9%; adverse reactions occurred in 29 lesions (30.5%). Of 138 lesions treated with the antioxidant gel containing tea polyphenols combined with phototherapy, 73 showed improvement, resulting in a total response rate of 52.9% and an average VASI improvement rate of 24.0%; adverse reactions occurred in 10 lesions (7.2%). In the positive control group, 74 lesions were treated, and 40 showed improvement, resulting in a total response rate of 54.1% and an average VASI improvement rate of 18.3%; adverse reactions occurred in 5 lesions (6.8%). Compared with the phototherapy group, the tea polyphenols combined group showed a significantly increased total response rate and a VASI improvement rate (both P < 0.01), but a significantly decreased incidence rate of adverse reactions ( P < 0.001). No significant differences in the above indicators were observed between the tea polyphenols combined group and the positive control group (all P > 0.05). In addition, the changes in skin barrier function and skin aging indicators (except for wrinkle depth) before and after treatment were significantly reduced in the tea polyphenols combined group compared to the phototherapy group (all P < 0.05). After the phototherapy alone, the transepidermal water loss significantly increased ( P = 0.004), and the water content of the stratum corneum significantly decreased ( P = 0.012). However, no significant differences in skin barrier function or skin aging indicators were found between pre- and post-treatment in the tea polyphenols combined group ( P > 0.05) . Conclusion:The antioxidant gel containing tea polyphenols could effectively improve the efficacy of narrow-band ultraviolet B in the treatment of vitiligo, and alleviate skin aging and barrier damage caused by phototherapy.

Objective:To investigate the predictive value of serum neutrophil gelatinase-associated lipocalin(NGAL),calcitonin gene-related peptide(CGRP),and neutrophil-to-lymphocyte ratio(NLR)for the prognostic regression of elderly patients with stroke complicated with pulmonary infection(SCPI).Methods:This study was a retrospective single-center study,149 elderly patients with SCPI who were admitted to Inner Mongolia Baogang Hospital from June 2020 to June 2024 were selected,they were divided into poor prognosis group(n=56)and good prognosis group(n=93)according to the prognosis.Baseline data and laboratory test indicators were collected,and NLR was calculated.Serum NGAL and CGRP levels were measured by ELISA.Influencing factors of poor prognosis of elderly patients with SCPI were analyzed by Multivariate logistic regression.Predicts value was analyzed by Receiver operating characteristic(ROC)curve.Results:Compared with good prognosis group,the poor prognosis group had higher of aged ≥ 70 years,incidence of hemorrhagic stroke,serum creatinine,white blood cell count,national institute of health stroke scale(NIHSS),platelet count,C-reactive protein,NGAL,and NLR levels,longer nerosurgery intensive care unit(NICU)stay,and lower CGRP levels(P＜0.05).Higher CGRP level was an independent protective factor of poor prognosis of elderly patients with SCPI(OR＜1,P＜0.05).Age ≥ 70 years,hemorrhagic stroke,longer NICU stay,higher NIHSS score,higher NGAL level and higher NLR were independent risk factors of poor prognosis of elderly patients with SCPI(OR＞1,P＜0.05).The area under the curve(AUC)for predicting the prognostic regression of elderly patients with SCPI used NGAL,CGRP,and NLR alone or in combination was 0.777,0.771,0.786,and 0.927,respectively,with the combination of three factors showed the highest predictive power(P＜0.05).Conclusion:Age ≥70 years,hemorrhagic stroke,longer NICU stay,higher NIHSS score,higher NGAL level and higher NLR are independent risk factors of poor prognosis of elderly patients with SCPI,while higher CGRP level is an independent protective factor.The combination detection of NGAL,CGRP and NLR can improve the predictive value of prognostic regression in elderly patients with SCPI.

Objective To analyze differences of purified water,softened water,and concentrated softened water on the decontamination effects for surgical instruments,so as to provide a reliable reference for the selection of cleaning water for surgical instruments.Methods The physical and chemical indexes and components of concentrated softened water,softened water,and purified water were detected,and their cleaning effects for instrument were compared.The decontamination cleaning experiment was conducted in three hospitals with different types of cleaning water using mini cleaning machines,and the differences in the decontamination time were analyzed.The cleaning and decontamination experiments on contaminated instruments was performed using a spray cleaning and disinfection device,and the cleaning effects of instruments with different types of cleaning water were analyzed.Results Calcium content and hardness of the three types of cleaning water were all at a low level,which can avoid scale adhesion for cleaning surgical instruments.There were statistically significant differences in the pH value,conductivity,and contents of calcium,sodium and chloride among the three cleaning waters(P<0.05).The purified water was weakly acidic,and its conductivity,hardness,and contents of calcium,sodium and chloride were all at low levels.The softened water and concentrated softened water were weakly alkaline,with high levels of conductivity and sodium content and low level of chloride.There were statistically significant differences in the decontamination time of the purified water,softened water and concentrated softened water among hospitals(P<0.05).Under the same contamination condition of surgical instruments,there was a statistically significant difference in the qualified rate of instruments cleaning in the upper and lower cleaning baskets with different cleaning waters(P<0.05).Conclusion Concentrated softened water and softened water have high sodium content,and their decontamination and cleaning abilities are significantly stronger than those of the purified water.Purified water has poorer effects in instruments cleaning for its deionized property.Using concentrated softened water or softened water in the surgical instrument cleaning process can achieve effects of reducing consumption and increasing efficiency,which is conducive to improving cleaning efficiency and quality.

Objective:To explore the predictive value of serum interleukin-6(IL-6)combined with Montreal Cognitive Assessment(MoCA)score and CHANGE risk score for post-stroke cognitive impairment(PSCI),and to provide a basis for early identification and intervention of high-risk patients.Methods:The general data of 200 patients with acute stroke who were admitted to our hospital from October 2022 to September 2024 were retrospectively analyzed,they were divided into PSCI group(49 cases)and non PSCI group(151 cases)based on whether PSCI occurred 3 months after acute stroke.The general data of two groups were compared,multiple logistic regression was used to analyze the influencing factors of PSCI,and receiver operating characteristic(ROC)curves were used to evaluate predictive efficiency of serum IL-6,MoCA score and CHANGE risk score for of PSCI.Results:There was a statistically significant difference in age and education level between the two groups(P＜0.05).The serum IL-6 level and CHANGE risk score in the PSCI group were higher than those in the non PSCI group,while the MoCA score was lower than that in the non PSCI group(P＜0.05).Multivariate logistic regression showed that elevated IL-6 levels(OR=1.851,P=0.001)and elevated CHANGE risk scores(OR=1.076,P=0.016)were independent risk factors of the occurrence of PSCI,while elevated in MoCA score(OR=0.806,P=0.001)was a protective factor(P＜0.05).IL-6 levels,MoCA scores and CHANGE risk scores have high predictive efficiency for the occurrence of PSCI,the area under the curve(AUC)for predicting occurrence of PSCI by the three alone were 0.783,0.825 and 0.857 respectively,the AUC for the combined detection of the three indicators was 0.912,significantly higher than that of each indicator detected separately.Conclusion:Elevated serum IL-6,decreased MoCA score and increased CHANGE risk score are risk factors for PSCI,the combined detection model of the three has the highest predictive efficiency for occurrence of PSCI and can provide scientific basis for early clinical intervention.
