Objective To explore the pharmacokinetic characteristics of sufentanil in individuals with normal body mass index(BMI),overweight BMI,and different CYP3A4/5 enzyme genotypes.Methods The patients receiving laparoscopic surgery under general anesthesia in the First Affiliated Hospital of Army Medical University from November 2020 to September 2021 were prospectively recruited in this study.Before the operation,the oral swabs were collected from all the patients for genotyping using the human CYP3A4/5 gene kit.Based on the potential impact of combination of their polymorphisms on sufentanil metabolism and the proportion of different genotype combinations of CYP3A4/5 enzymes,the patients were divided into groups I(3A4 homozygous mutation or 3A4 heterozygous mutation+3A5 homozygous mutation),II(3A4 heterozygous mutation+3A5 heterozygous mutation),and III(3A4 wild type or 3A4 heterozygous mutation+3A5 wild type).According to their BMI,they were also assigned into a normal body weight group(18.5～24.0 kg/m2)and an overweight group(24～<28 kg/m2),and the differences in drug metabolism parameters were statistically analyze between the 2 groups.After routine general anesthesia induction(sufentanil 0.5 μg/kg),venous blood samples were collected to detect the changes in its concentration using high performance liquid chromatography-mass spectrometry(HPLC-MS).The pharmacokinetic data of sufentanil were calculated between the normal BMI group and overweight group in all participants and between the 2 body weight groups among those with different genotype combinations.Results Among the 90 participants completing the blood drug concentration test,8 patients had their blood samples contaminated(including 1 case with an anesthesia duration of<2 h),and 3 were excluded due to low weight or overweight.Eventually,79 participants were included in the pharmacokinetic analysis on the normal body weight group and the overweight group.Compared with the normal body weight group,the central compartment volume of distribution in the overweight group was significantly reduced(P<0.05),while no obvious differences were observed between the 2 groups in terms of peripheral compartment volume of distribution,total clearance rate,peripheral compartment clearance rate,distribution half-life,clearance half-life,and area under the blood concentration-time curve.In group Ⅰ(n=26),the overweight patients(n=13)had significantly reduced central compartment volume of distribution,peripheral compartment volume of distribution,and peripheral compartment clearance rate when compared with the normal body weight patients(n=13)(P<0.05),while no differences were observed in other pharmacokinetic parameters.In groups Ⅱ(n=25)and Ⅲ(n=28),the overweight patients and normal body weight patients had no statistical differences in all pharmacokinetic parameters.Conclusion Among the patients with the same genotype combination of CYP3A4/5 mutations,there was no difference in the metabolism of sufentanil between the overweight and normal weight patients.Additionally,in the population of 3A4 homozygous mutation or 3A4 heterozygous mutation+3A5 homozygous mutation,the overweight patients have smaller peripheral distribution range of sufentanil,and weakened metabolic process.

Objective:To explore the clinical efficacy of modified Chaihu Jia Longgu Muli Decoction in patients with liver and kidney Yin deficiency syndrome of Parkinson's disease (PD) and the effects on phosphatase and tensin homolog-induced putative kinase 1 (PINK1) /E3 ubiquitin ligase (Parkin) signaling pathway.Methods:A randomized controlled trial study was conducted. A total of 120 PD patients from the Department of Encephalopathy of Xi'an Hospital of Traditional Chinese Medicine from May 2020 to May 2024 were selected as the observation objects and divided into 2 groups through random number table method, with 60 cases in each group. The control group took dopashydrazine tablets orally, while the combined group took Chaihu Jia Longgu Muli Decoction on the basis of the control group. Two groups were treated continuously for 2 months. The levels of glial cell-derived neurotrophic factor (GDNF), nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and basic fibroblast growth factor 2 (FGF2) were detected by ELISA. The expression levels of PINK1, Parkin and chelate 1 (SQSTM1) mRNA were detected by real-time fluorescence quantitative PCR. The adverse reactions during the treatment were observed and recorded to evaluate the clinical efficacy.Results:The total effective rate was 95.00% (57/60) in the combined group and 83.33% (50/60) in the control group, with statistical significance ( χ2=4.23, P=0.040). After treatment, the levels of serum GDNF [(510.78±31.57) ng/L vs. (431.89±30.45) ng/L, t=13.93], BDNF [(36.47±3.72) ng/L vs. (27.84±3.55) ng/L, t=13.00], NGF [(57.24±4.17) ng/L vs. (50.72±4.11) ng/L, t=8.63] and FGF2 [(26.21±3.71) ng/L vs. (21.63±3.54) ng/L, t=6.92] in the combined group were higher than those in the control group ( P<0.001). After treatment, the mRNA expression levels of PINK1 (2.38±0.07 vs. 2.19±0.05, t=17.11), Parkin (1.89±0.03 vs. 1.74±0.05, t=19.93), and SQSTM1 (1.82±0.07 vs. 1.61±0.05, t=18.91) in the combined group were higher than those in the control group ( P<0.001). During the treatment period, the incidence of adverse reactions was 6.67% (4/60) in the combined group and 10.00% (6/60) in the control group, without statistical significance ( χ2=0.44, P=0.509). Conclusion:Modified Chaihu Jia Longgu Muli Decoction can increase the levels of neurotrophic factors in patients with PD of liver and kidney yin deficiency syndrome, regulate the PINK1/Parkin pathway, protect neurons, improve mitochondrial autophagy function, and enhance clinical efficacy.

In terms of the complexity of the"left"and"right"concepts,these directional terms not only indicate spatial orientation but also embody hierarchical order,official titles,systemic imbalances,and temporal sequences.This study explains the medical theory of"liver is born on the left and lung is hidden on the right,"and reveals its implications for ascending and descending of qi movement pathways,sequential patterns,non-equilibrium states,and the centrality of the middle,thus linking the connotation of this theory and its application.In view of this,the theory of"liver is born on the left and lung is hidden on the right"can be used in the clinical diagnosis and treatment of qi-blood-body fluid and emotional diseases,and guides disease prevention and treatment,as well as enhances the subjective initiative of health maintenance and longevity.This study not only deepens the modern interpretation of the classical theory but also provides novel perspectives for its application in disease prevention and treatment.

Objective:To investigate the clinical distribution characteristics changes in antimicrobial resistance, and carbapenemase resistance genes of Klebsiella pneumoniae isolated from children in Chongqing region during the period of January 2019 to December 2024, providing a basis for the rational use of antibiotics and the prevention and control of nosocomial infections.Methods:An observational study was conducted to retrospectively analyze 5 020 Klebsiella pneumoniae (KP) isolates detected in four hospitals of the Southwest Pediatric Laboratory Specialty Alliance. Antimicrobial susceptibility testing was performed by the minimum inhibitory concentration method combined with the disk diffusion method. Results were interpreted according to the 2024 Clinical and Laboratory Standards Institute (CLSI) standards. Carbapenemase resistance genes were detected by polymerase chain reaction (PCR) combined with Sanger sequencing. WHONET 5.6 was used for resistance analysis and SPSS 19.0 for statistical analysis. The chi-square test was used to assess trends in resistance rates, ESBL detection rates, and resistance rates of different CRKP carbapenemase genotypes from 2019 to 2024. Statistical significance was confirmed if the two-tailed P-value was <0.05. Results:A total of 5 020 strains were isolated, with a detection rate of 5.1% (5 020/99 063). The majority were from sputum (59.2%, 2 970/5 020), followed by pus (17.1%, 857), urine (9.7%, 487), venous blood (6.5%, 326), secretions (2.6%, 130), and other specimens (5.0%, 250).The lowest resistance rate was to amikacin (3.8%), followed by levofloxacin (10.9%), imipenem (19.1%), and meropenem (19.9%). Resistance rates to cefoperazone/sulbactam ( χ2=9.982 0, P=0.001 6), piperacillin/tazobactam ( χ2=10.110 0, P=0.001 5), ceftazidime ( χ2=3.849 0, P=0.049 8), cefotaxime ( χ2=7.605 0, P=0.005 8), cefepime ( χ2=13.510 0, P=0.000 2), aztreonam ( χ2=6.457 0, P=0.011 1), imipenem ( χ2=4.672 0, P=0.030 7), and levofloxacin ( χ2=7.555 0, P=0.006 0) showed an annual increasing trend. The main carbapenemase genes were blaNDM-5 (42.2%, 127/301), blaNDM-1 (33.9%, 102/301), and blaKPC-2 (17.3%, 52/301). Patients with KPC-2-producing strains (median age, 240 days) were older than those with NDM-1/NDM-5-producing strains (median age, 40 days) ( χ2=22.620 0, P<0.000 1). In neonatal wards, the detection rate of NDM-KP was higher than that of KPC-KP (64.6%, 148/229 vs. 26.9%, 14/52, χ2=24.680 0, P<0.000 1), whereas in ICUs, it was lower (6.1%, 14/229 vs. 26.9%, 14/52, χ2=20.450 0, P<0.000 1). Conclusion:In Chongqing region, the isolation rate of K. pneumoniae from sputum was the highest with most cases from neonatal wards. Resistance to carbapenems showed an upward trend. BlaNDM-5 was the predominant genotype in pediatric CRKP. Patients with KPC-KP were older than those with NDM-KP. NDM-KP predominated in neonatal wards, while KPC-KP predominated in ICUs, with KPC-KP showing higher antimicrobial resistance.

Viruses constitute a significant group of pathogens that have caused numerous fatalities and substantial economic losses in recent years, particularly with the emergence of coronaviruses. While the impact of SARS-CoV-2 appears to be diminishing in daily life, only a limited number of drugs have received approval or emergency use authorization for its treatment. Given the high mutation rate of viral genomes, host-directed agents (HDAs) have emerged as a preferred choice due to their broad applicability and lasting effectiveness. In contrast to direct-acting antivirals (DAAs), HDAs offer several advantages, including broad-spectrum antiviral activities, potential efficacy against future emerging viruses, and a lower likelihood of inducing drug resistance. In our review article, we have synthesized known host-directed antiviral targets that span diverse cellular pathways and mechanisms, shedding light on the intricate interplay between host cells and viruses. Additionally, we have provided a brief overview of the development of HDAs based on these targets. We aim for this comprehensive analysis to offer valuable perspectives and insights that can guide future antiviral research and drug development efforts.

Objective To explore the characteristics of traditional Chinese medicine(TCM)syndrome elements in patients with chronic heart failure(CHF)and their correlation with long-term prognosis,thus to provide an objective basis for clinical treatment of CHF.Methods From January 2006 to July 2014,a retrospective analysis was carried out in 546 patients diagnosed as CHF in the Cardiology Department of Guang'anmen Hospital,China Academy of Chinese Medical Sciences.TCM syndrome elements of the patents were determined based on the data collected by four diagnostic methods.Patients were followed up for a maximum of 1 330 days,and long-term prognosis was recorded.With the patient's death as the endpoint event,and the patients were divided into a survival group(291 cases)and a death group(255 cases)according to the endpoint event.The distribution of TCM syndrome elements in the two groups was observed,and differences in the combination patterns of TCM syndrome elements were compared.After that,the correlation between long-term prognosis and TCM syndrome elements in CHF patients was analyzed.Results(1)The age of patients in the death group was greater and serum N-terminal pro-brain natriuretic peptide(NT-proBNP)level was higher than that in the survival group,the differences being statistically significant(P＜0.01).In terms of New York Heart Association(NYHA)functional classification,the patients of death group had low proportion of heart function level Ⅲ while high proportion of heart function level Ⅳ in comparison with the patients of survival group,the differences being statistically significant(P＜0.05 or P＜0.01).Statistically significant differences were presented in the cardiac ultrasound indicators of left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),and right ventricular end-diastolic diameter(RVEDD)between the two groups(P＜0.05 or P＜0.01),while left atrial diameter(LA)showed no significant difference between the two groups(P＞0.05).In terms of underlying diseases,the proportion of coronary heart disease in the death group(87.45%)was higher than that in the survival group(80.76%),with a statistically significant difference(P＜0.05).No significant differences were presented in other underlying diseases(P＞0.05).(2)The death group had more cases of qi deficiency and yin deficiency syndrome elements while less cases of qi stagnation syndrome element than the survival group,and the differences were statistically significant(P＜0.05 or P＜0.01).The death group had higher proportions of syndrome element combinations such as qi deficiency and yin deficiency with blood stasis,yang deficiency and blood stasis with phlegm-heat,qi deficiency and yin deficiency with phlegm-heat,and yang deficiency and blood stasis with phlegm turbidity than the survival group,and the differences were statistically significant(P＜0.05 or P＜0.01).Conclusion CHF has the prognosis of developing into yin deficiency or yang deficiency.The death group has higher proportions of qi deficiency and yin deficiency with blood stasis syndrome,and yang deficiency and blood stasis with phlegm turbidity syndrome than the survival group,indicating that there is a poor prognosis,and more attention and early intervention should be done to avoid adverse events.
