The auxin/indole-3-acetic acid (Aux/IAA) gene family is an important regulator for plant growth hormone signaling, involved in plant growth, development, as well as response to environmental stresses. In the present study, we identified SmIAA7 which is potentially associated with Salvia miltiorrhiza leaf development through comparatively analyzed the transcriptome data from different pinnate leaves. SmIAA7 was successfully isolated from S. miltiorrhiza using the specific primers. Then subsequent bioinformatic analysis, prokaryotic expression and purification, subcellular localization, and induction expression analysis under auxin and abiotic stress were performed. The full-length of SmIAA7 contained an ORF of 684 bp encoding a protein of 227 amino acid with a molecular weight of 25.3 kD. Conserved domain analysis showed that SmIAA7 contains the conserved Aux_IAA domain (pfam02309). Sequence analysis and phylogenetic tree analysis results indicated SmIAA7 was phylogenetically close to IAA7 and IAA14 from other plants, suggesting SmIAA7 involved in plant growth and development as well as response to environmental stresses. The prokaryotic expression vector pET28a-SmIAA7 was constructed and SmIAA7 recombinant protein was successfully expressed in E. coli Rosetta (DE3) strain. Subcellular localization experiment demonstrated that SmIAA7 localized in the nucleus of plant cells. Real-time fluorescence quantitative PCR results showed that the expression level of SmIAA7 was upregulated in response to auxin. Drought, low temperature, and salt stress significantly increased the transcript level of SmIAA7 gene. This study lays a foundation for further elucidating the role of SmIAA7 in leaf development, signal transduction, and stress defense in S. miltiorrhiza.

Objective:To compare the difference between the Evidence Quality Grading System for Public Health Decision-making(PHE-Grading)and the Grading of Recommendations Assessment,Development and Evaluation(GRADE)System in evaluating the quality of evidence for public health decision-making.Methods:Systematic reviews about topic"Public health"were electronically searched in the Cochrane Library database from inception to February 27,2024.EndNote 20 software was used for literature screening,Excel 2021 and SPSS 22.0 software were used for data collation and analysis,and the forest plot was drawn by RevMan 5.4.1 software.Results:A total of 61 systematic reviews were finally included for evidence quality evaluation.The forest plot of GRADE and PHE-Grading evidence grading results showed that high grade[OR:2.39,95%CI(1.21 to 4.75)],moderate grade[OR:0.40,95%CI(0.31 to 0.52)],low grade[OR:0.37,95%CI(0.29 to 0.46)],and extremely low grade[OR:85.11,95%CI(34.80 to 208.11)],and the differences in evidence quality grading results between the two systems were statistically significant.Conclusions:Compared with GRADE,PHE-Grading may be more accurate in grasping the certainty of public health decision-making evidence.Currently,the quality of public health decision-making evidence is still concentrated in low and middle level,and high-quality research still needs to be strengthened to support scientific decision-making.

Glyceryl phenylbutyrate(GPB)serves as a long-term management medication for Ornithine transcarbamylase deficiency(OTCD),effectively controlling hyperammonemia,but there is a lack of experience in using this medicine in China.This article retrospectively analyzes the case of a child diagnosed with OTCD at Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine,including a review of related literature.After diagnosis,the patient was treated with GPB,followed by efficacy follow-up and pharmacological monitoring.The 6-year and 6-month-old male patient exhibited poor speech development,disobedience,temper tantrums,and aggressive behavior.Blood ammonia levels peaked at 327 μmol/L;urine organic acid analysis indicated elevated uracil levels;cranial MRI showed extensive abnormal signals in both cerebral hemispheres.Genetic testing revealed de novo mutation in the OTC gene(c.241T＞C,p.S81P).Blood ammonia levels were approximately 43,80,and 56 μmol/L at 1,2,and 3 months after starting GPB treatment,respectively.During treatment,blood ammonia was well-controlled without drug-related adverse effects.The patient showed improvement in developmental delays,obedience,temperament,and absence of aggressive behavior.

Objective To explore the clinical efficacy and influencing factors of omadacycline(OMC)in the treat-ment of patients with infectious diseases.Methods Data about hospitalized patients who received OMC monothera-py or combination therapy at Xiangya Hospital of Central South University from January 2022 to December 2023 were analyzed retrospectively.The influencing factors for failure of OMC treatment was analyzed by univariate and multivariate logistic regression analysis.Results A total of 160 patients were included in analysis,with an overall effective treatment rate of 69.4％(n=111).After treatment with OMC,patients in effective group was observed that body temperature improved([36.83±0.52]℃ vs[37.85±0.92]℃,P＜0.001),white blood cell count([7.78±4.07]× 109/L vs[10.06±6.49]× 109/L,P＜0.001),procalcitonin([0.63±1.19]ng/mL vs[4.43±10.14]ng/mL,P=0.001),C-reactive protein([35.16±37.82]mg/L vs[105.08±99.47]mg/L,P＜0.001),and aspartate aminotransferase([50.50±40.04]U/L vs[77.17±91.43]U/L,P=0.004)all decreased signifi-cantly.Only one patient had adverse reactions such as diarrhea,but treatment was not interrupted.Univariate ana-lysis showed that patients in failure treatment group had a higher acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score(17.0[9.5-22.0]vs 12.0[9.0-19.0],P=0.046)and sequential organ failure assessment(SOFA)score(7.0[4.5-10.0]vs 4.0[2.0-9.0],P=0.019).Multivariate analysis showed that end-stage liver disease(OR=77.691,95％CI:5.448-1 107.880,P=0.001),mechanical ventilation(OR=6.686,95％CI:1.628-27.452,P=0.008)and the combination treatment of vancomycin(OR=6.432,95％CI:1.891-21.874,P=0.003)were risk factors for the failure of OMC treatment,while the course of OMC treatment(OR=0.905,95％CI:0.825-0.994,P=0.037)was a protective factor for the effective treatment.Conclusion OMC can be used as an alternative therapy for refractory severe infection,with fewer adverse reaction.End-stage liver disease,mechanical ventilation and combination treatment of vancomycin are risk factors for failure of OMC treatment in in-fected patients.Adequate OMC treatment course can improve patients'clinical outcome,large-scale case studies are needed to confirm the initial conclusion.

ObjectiveTo explore the protective effects and potential mechanism of Zuogui Jiangtang Yishen prescription （ZJYP） in Goto-Kakizaki （GK） rats with early-stage diabetic kidney disease （DKD）. MethodFifty 12-week-old male GK rats were included in this study. DKD was induced after one month of high-fat feeding， with fasting blood glucose （FBG） ≥ 11.1 mmol·L^-1 and urinary albumin/creatinine ratio （ACR） ≥ 30 mg·g^-1 used as model criteria. After successful modeling， DKD rats were randomly divided into five groups （n=10 in each group）： the model group， the western medicine group treated with dapagliflozin （1.0 mg·kg^-1·d^-1）， low-， medium-， and high-dose ZJYP groups （4.9， 9.9， 19.9 g·kg^-1·d^-1 by gavage）. Ten Wistar rats served as normal controls， with both the normal and model groups receiving physiological saline in the same volume as the treatment groups by gavage for 8 weeks. The urinary ACR， FBG， body weight， and liver and kidney functions of the rats were observed. Renal tissues were subjected to haematoxylin-eosin （HE） and periodic acid-Schiff （PAS） staining and examined under an electron microscope to observe pathological changes. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect miRNA-27a， Wnt， and β-catenin mRNA and protein expression levels in renal tissues. ResultCompared with the results in the normal group， the FBG levels in DKD rats of the model group increased significantly at 0， 2， 4， 6， and 8 weeks of drug intervention （P<0.05）， and urinary ACR increased significantly at 0， 4， 8 weeks （P<0.05）. Renal pathological staining and electron microscopy revealed an increase in mesangial cells and matrix， slight thickening of the basement membrane， and increased interstitial fibrosis and renal tubular atrophy in the model group. The mRNA expression levels of miRNA-27a， Wnt， and β-catenin were significantly higher in the model group than in the normal group （P<0.05）. Renal Wnt and β-catenin protein levels were also significantly higher in the model group （P<0.05）. After drug intervention， the FBG levels in the low-， medium-， and high-dose ZJYP groups showed a dose-dependent decrease compared with those in the model group at 6 and 8 weeks （P<0.05）. The urinary ACR also showed a dose-dependent decrease in the low-， medium-， and high-dose ZJYP groups， but the differences were not statistically significant. There were no significant differences in liver function， renal function， renal index， or routine blood lipid test results among the low-， medium-， and high-dose ZJYP groups. Renal glomerular and tubular lesions were milder in the ZJYP groups and the western medicine group than in the model group， with similar pathological changes observed in the high-dose ZJYP group and the western medicine group. The renal mRNA levels of miRNA-27a， Wnt， and β-catenin were significantly lower in the high-dose ZJYP group （P<0.05）， and renal Wnt and β-catenin protein levels were significantly lower in both the western medicine group and the high-dose ZJYP group compared with the levels in the model group （P<0.05）. The Wnt and β-catenin protein levels were lower in the renal tissues of the low- and medium-dose ZJYP groups compared with the levels in the model group， but the differences were not statistically significant. ConclusionZJYP can effectively improve glucose metabolism and alleviate early damage in DKD rats， thereby delaying the progression of DKD. Its mechanism may be related to the inhibition of the miRNA-27a/Wnt/β-catenin signaling pathway in renal tissues.

italic>Schisandra chinensis is a traditional Chinese medicine with the functions of reinforcing deficiency, strengthening, and inducing astringency, appliable to treat the chronic cough and deficiency in breath, palpitation, and insomnia, etc. A hybrid mass spectrometry scanning strategy (high-definition data-independent/data-dependent acquisition, HDDIDDA), enabling the ion mobility separation and alternating data-independent acquisition/data-dependent acquisition, was established, which, in combination with in-house library-driven automatic peak annotation workflows facilitated by the UNIFI software, was utilized to systematically characterize the multi-classes of chemical components from S. chinensis. The use of an HSS T3 column (100 mm × 2.1 mm, 1.8 μm), 0.1% formic acid in H₂O-acetonitrile as the mobile phase running at the flow rate of 0.3 mL·min^-1, and column temperature at 35 ℃, could enable good separation of the S. chinensis components within 42 min. HDDIDDA scan in both the positive and negative ion modes was employed for data acquisition. Based on the automatic peak annotation, reference standards comparison, MS² data interpretation, and literature analysis, we were able to identify or tentatively characterize 105 compounds in the S. chinensis decoction, involving 56 terpenoids, 42 lignans, five glycosides, one organic acid, and one flavonoid. HDDIDDA scanning can improve the coverage of data acquisition and improve the accuracy of identification, while CCS prediction analysis provides the possibility to distinguish isomers by the ion mobility technology. The results provide reference for the intelligent material basis research of TCM.
