Suhuang Zhike Capsules are widely used in clinical practice for the treatment of respiratory diseases and have been included in Medicine Catalogue for National Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance and National Essential Medicines List. However, problems remain, such as unclear definitions of treatment courses and unidentified contraindications for certain populations. Therefore, this consensus was developed collaboratively by clinical experts in traditional Chinese medicine(TCM) related to pulmonary diseases, respiratory, and critical care medicine, as well as methodology and pharmacy experts, adhering strictly to the consensus development procedures established by the China Association of Chinese Medicine for clinical application of Chinese patent medicines, with the aim to guide the correct clinical use of Suhuang Zhike Capsules for the treatment of cough variant asthma, post-infectious cough, and other respiratory diseases. This consensus employed questionnaire surveys and expert interviews to identify clinical concerns based on the PICOS principle and conduct evidence evaluation and GRADE grading. Utilizing nominal group techniques and GRADE networking methods, it resulted in 17 recommendations and consensus suggestions. The consensus further clarifies the indications, TCM syndromes, usage, and clinical safety of Suhuang Zhike Capsules in the treatment of cough variant asthma and post-infectious cough, aiming to promote standardized medication use and facilitate the rational clinical application of Suhuang Zhike Capsules.

We propose a strategy to reduce unnecessary prostate biopsies in Chinese patients with total prostate-specific antigen (tPSA) >10 ng ml -1 and Prostate Imaging Reporting and Data System (PI-RADS) scores between 1 and 3. Clinical data derived from 517 patients of The First Affiliated Hospital of USTC (Hefei, China) from January 2020 to December 2023 who met the screening criteria for the study were retrospectively collected. Independent predictors were identified via univariate and multivariate logistic regression analysis. The diagnostic capacity of clinical variables was evaluated using the receiver operating characteristic (ROC) curves and area under the curve (AUC). A prostate biopsy strategy was developed via risk stratification. Of the 517 patients, 17/348 (4.9%) with PI-RADS 1-2 were diagnosed with clinically significant prostate cancer (csPCa), and 27/169 (16.0%) patients with PI-RADS 3 were diagnosed with csPCa. The appropriate prostate-specific antigen density (PSAD) cut-off values were 0.45 ng ml -2 for PI-RADS 1-2 patients and 0.3 ng ml -2 for PI-RADS 3 patients. The appropriate prostate volume (PV) cut-off values were 40 ml for PI-RADS 1-2 patients and 50 ml for PI-RADS 3 patients. The prostate biopsy strategy based on PSAD and PV developed in this study can reduce unnecessary prostate biopsies in patients with tPSA >10 ng ml -1 and PI-RADS 1-3. In the study, 66.5% (344/517) patients did not need to undergo prostate biopsy, at the expense of missing only 1.7% (6/344) patients with csPCa.

BACKGROUND: Medical informatics accumulated vast amounts of data for clinical diagnosis and treatment. However, limited access to follow-up data and the difficulty in integrating data across diverse platforms continue to pose significant barriers to clinical research progress. In response, our research team has embarked on the development of a specialized clinical research database for cardiology, thereby establishing a comprehensive digital platform that facilitates both clinical decision-making and research endeavors. METHODS: The database incorporated actual clinical data from patients who received treatment at the Cardiovascular Medicine Department of Chinese PLA General Hospital from 2012 to 2021. It included comprehensive data on patients' basic information, medical history, non-invasive imaging studies, laboratory test results, as well as peri-procedural information related to interventional surgeries, extracted from the Hospital Information System. Additionally, an innovative artificial intelligence (AI)-powered interactive follow-up system had been developed, ensuring that nearly all myocardial infarction patients received at least one post-discharge follow-up, thereby achieving comprehensive data management throughout the entire care continuum for high-risk patients. RESULTS: This database integrates extensive cross-sectional and longitudinal patient data, with a focus on higher-risk acute coronary syndrome patients. It achieves the integration of structured and unstructured clinical data, while innovatively incorporating AI and automatic speech recognition technologies to enhance data integration and workflow efficiency. It creates a comprehensive patient view, thereby improving diagnostic and follow-up quality, and provides high-quality data to support clinical research. Despite limitations in unstructured data standardization and biological sample integrity, the database's development is accompanied by ongoing optimization efforts. CONCLUSION The cardiovascular specialty clinical database is a comprehensive digital archive integrating clinical treatment and research, which facilitates the digital and intelligent transformation of clinical diagnosis and treatment processes. It supports clinical decision-making and offers data support and potential research directions for the specialized management of cardiovascular diseases.

The xylitol dehydrogenase(XDH)is a crucial enzyme involved in the xylose utilization in pentose-catabolizing yeasts and fungi.In addition to producing xylulose,XDH can also be employed to develop a biosensor for monitoring xylitol concentration.In this study,the gene encoding the thermophilic fungus Talaromyces emersonii XDH(TeXDH)was heterologously expressed in Escherichia coli BL21(DE3)at 16 ℃ in the soluble form.Recombinant TeXDH with high purity was purified by using a Ni-NTA affinity column.Size-exclusion chromatography and SDS-PAGE analysis demonstrated that the puri-fied recombinant TeXDH exists as a native trimer with a molecular mass of approximately 116 kD,and is composed of three identical subunits,each with a molecular weight of around 39 kD.The TeXDH strictly preferred NAD+as a coenzyme to NADP+.The optimal temperature and pH of the TeXDH were 40 ℃and 10.0,respectively.After EDTA treatment,the enzyme activity of TeXDH decreased to 43.26％of the initial enzyme activity,while the divalent metal ions Mg2+or Ca2+could recover the enzyme activity of TeXDH,reaching 103.32％and 110.69％of the initial enzyme activity,respectively,making them the optimal divalent metal ion cofactors for TeXDH enzyme.However,the divalent metal ions of Mn2+,Ni2+,Cu2+,Zn2+,Co2+,and Cd2+significantly inhibited the activity of TeXDH.ICP-MS and molecular doc-king studies revealed that 1 mol/L of TeXDH bound 2 mol/L Zn2+ions and 1 mol/L Mg2+ion.Further-more,TeXDH exhibited a high specificity for xylitol,laying the foundation for the development of future xylitol biosensors.

Background and aims:Advanced hepatocellular carcinoma(HCC)with pulmonary metastasis(PM)has a poor prognosis,and optimal treatment strategies remain controversial.This study aimed to compare the long-term outcomes of patients with advanced HCC with PM who were treated with resection of pul-monary metastases versus those treated with targeted therapies combined with immunotherapy.Methods:A retrospective analysis was conducted on the medical records of HCC patients with PM who underwent either pulmonary metastasectomy or immunotherapy combined with targeted therapies at the Eastern Hepatobiliary Surgery Hospital,Changhai Hospital of Shanghai,Fujian Provincial Hospital,and West China Hospital of Sichuan University from September 2013 to October 2022.One-to-one propensity score matching(PSM)was employed to control the influence of potential confounders,and the survival outcomes were compared.Results:A total of 119 HCC patients with PM were included in this study.The overall survival(OS)of patients who underwent pulmonary metastasectomy was significantly longer than that of patients who received immunotherapy targeted combinations(OS:1-year,80.0％vs.59.3％;2-year,31.7％vs.20.3％;3-year,20.0％vs.0;P＜0.001).After PSM,the long-term prognosis of the pulmonary metastasectomy group remained significantly better than that of the immunotherapy combination group(OS:1-year,87.0％vs.69.6％;2-year,34.8％vs.30.4％;3-year,21.7％vs.0;P=0.005).Multivariate analysis revealed that treat-ment allocation(hazard ratio(HR)=2.177,95％confidence interval(CI)=1.068-4.439)and hepatic tumor T stage(HR=2.342,95％CI=1.209-4.538)were independent risk factors for OS.Conclusions:Pulmonary metastasectomy was associated with improved survival compared to immu-notherapy combined with targeted therapies and may represent an optimal treatment option for highly selected HCC patients with resectable PM.

Objective:To explore the relationship between medical students'family function and anxiety/depression,and the mediating role of loneliness in this relationship.Methods:A total of 577 medical students were surveyed using stratified cluster sampling.Questionnaires assessed family function,loneliness,anxiety,and depression.Spearman correlation analysis was used to examine the relationships among family function,loneliness,anxiety,and depression.The mediating effects were tested using SPSS 26.0 PROCESS program model 4.Results:Medical students'family function,loneliness,anxiety,and depression scores were 8.00(5.00,10.00),16.00(12.00,19.00),3.00(2.00,4.00),and 3.00(2.00,4.00),respectively.Spearman correlation analysis showed that family function was negatively correlated with loneliness(r=-0.337),anxiety(r=-0.237),and depression(r=-0.257)(all P＜0.01).Loneliness was positively correlated with anxiety(r=0.394)and depression(r=0.392)(both P＜0.01).Anxiety was positively correlated with depression(r=0.746,P＜0.01).Family function negatively predicted anxiety(β=-0.118,P＜0.01),depression(β=-0.105,P＜0.01),and loneliness(β=-0.322,P＜0.01).Loneliness positively predicted anxiety(β=0.348,P＜0.01)and depression(β=0.346,P＜0.01).Loneliness played a partial mediating role in the relationship of family function with anxiety and depression among medical students,with mediating effects of 49.0%and 43.2%,respectively.Conclusions:Family function not only directly affects medical students'anxiety and depression but also indirectly affects them by influencing loneliness.Therefore,improving medical students'family function can effectively reduce their loneliness,thereby helping to alleviate anxiety and depression.

Purpose Based on multimodal imaging combined with a variety of histological techniques,to visually evaluate the changes of rats brain metabolic microenvironment after cerebral hypoxia and ischemia of prematurity,and to discuss the effects of abnormal lactate metabolism in the brain on oligodendrocyte precursor cells,so as to provide a basis for the early diagnosis and treatment of premature white matter injury(PWMI).Materials and Methods A total of 36 SPF-grade healthy 3-day-old Sprague-Dawley neonatal rats were randomly assigned to the sham surgery(Sham)group and the model(PWMI)group using a random number table method,with 18 rats in each group.A neonatal rat PWMI model was established by hypoxia-ischemia method.Twenty-four hours after modeling,laser speckle imaging was used to monitor cerebral blood flow and blood oxygen changes.Multimodal imaging was used to observe the changes in brain tissue microstructure and metabolism after PWMI.HE staining was used to observe the morphological changes of nerve cells in the white matter of the brain.Enzyme-linked immunosorbent assay was used to detect the changes of lactate content and lactate dehydrogenase activity in the white matter region of the brain after PWMI in neonatal rats.PDGFR-α immunofluorescence staining was used to observe the dynamic changes of the number of oligodendrocyte precursor cells in the subependymal zone after PWMI in neonatal rats.Results Twenty-four hours after modeling,the multimodal imaging results showed that the T2WI and diffusion-weighted imaging on the injured side of the PWMI group showed high intensity,and the relative cerebral blood flow,relative oxygen saturation,relative apparent diffusion coefficient and amide proton transfer(APT)Lorentzian difference value were lower than those in the Sham group(t=29.466,23.522,59.006,54.778,10.263,all P<0.001),and the lactate content was higher than that in the Sham group(t=-7.521,P<0.001).The results of HE staining and enzyme-linked immunosorbent assay showed that the arrangement of nerve cells in the white matter area of the injured side of the brain in the PWMI group was loose and disordered.The lactate content and lactate dehydrogenase activity were higher than those in the Sham group(t=-6.079,-10.548,both P<0.001).The results of immunofluorescence staining showed that the number of PDGFR-α+cells in the subependymal zone of the damaged side of the PWMI group was higher than that of the Sham group at 24 hours after modeling,and lower than that in the Sham group at 11 days after modeling(t=-8.386,6.676,both P<0.001).The correlation analysis between the lactate content and APT Lorentzian difference value in the brain and the number of oligodendrocyte precursor cells in the brain 11 days after modeling showed that the number of oligodendrocyte precursor cells in the subependymal zone was positively correlated with the APT Lorentzian difference value(r=0.821,P=0.001 1),and negatively correlated with the lactate content in the brain(r=-0.880,P=0.000 2).Conclusion Multimodal imaging can monitor the early brain metabolism changes of PWMI in neonatal rats,especially the changes of lactate,and provide a visual basis for their early diagnosis.The level of lactate in the brain increases after cerebral hypoxia and ischemia in prematurity,and oligodendrocyte precursor cells increase transiently and then decrease,resulting in PWMI.

Objective To explore the application effect of dexmedetomidine combined with ropivacaine for quadratus lumborum block at the lateral supra-arcuate ligament(QLB-LSAL) in open hepatocellular carcinoma resection.Methods A prospective study was conducted in 60 patients who underwent elective open hepatocellular carcinoma resection at Jining First People's Hospital. The patients were randomly divided into the compound group and the control group,with 30 cases in each group. Patients in the compound group received QLB-LSAL combined general anesthesia,and patients in the control group received simple general anesthesia. All patients underwent patient controlled intravenous analgesia (PCIA)postoperatively. The mean arterial pressure (MAP),heart rate (HR) and visual analogue scale (VAS) scores during rest and coughing at different time points were observed and compared between the two groups. The number of postoperative PCIA compressions,the dosage of sufentanil,the first postoperative exhaust time,the first postoperative ambulation time,the hospital stay and the occurrence of adverse reactions of the two groups were recorded. Results In the compound group,the HR and MAP were significantly lower than those of the control group at the time of skin incision (T2) and at the end of surgery (T3);the VAS scores during rest and coughing were significantly lower than those of the control group at the time of exiting the anesthesia recovery room and 6 hours and 12 hours after surgery;and the PCIA compression times were significantly less than those of the control group;the dosage of sufentanil was significantly lower than that in the control group 0 to 24 hours after surgery,and the dosage of sufentanil was higher than that in the control group 25 to 48 hours after surgery;the first postoperative ambulation time and the first postoperative exhaust time were significantly earlier than those in the control group;and the above differences were statistically significant(P<0.05). There was no significant difference in the HR or MAP at 5 minutes into the operating room (T0) and 5 minutes before skin incision (T1),VAS scores during rest and coughing 24 hours and 48 hours after surgery,hospital stay and incidence of adverse reactions between the two groups (P>0.05).Conclusion For patients with open hepatocellular carcinoma resection,dexmedetomidine combined with ropivazine for QLB-LSAL can provide more ideal postoperative analgesia,reduce perioperative opioid consumption,and have less impact on circulatory system,which is conducive to rapid postoperative recovery.

Objective We aimed to evaluate the efficacy and safety of Shengxuebao Mixture in the treatment of cancer-related anemia(CRA)presenting with syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood.Methods A randomized,double-blind,placebo-controlled,multicenter clinical trial was conducted.Eligible patients with malignant tumors meeting the inclusion and exclusion criteria were enrolled from 26 hospitals,including Dongzhimen Hospital,Beijing University of Chinese Medicine,Xiaogan Central Hospital,and Yangzhou Hospital of Traditional Chinese Medicine,from June 1,2022,to September 30,2024.Patients were allocated 1:1 to either the experimental group receiving Shengxuebao Mixture or the control group receiving its simulator(placebo)using a block randomization method under double-blind conditions.Both groups received 15 mL orally three times daily for 28 consecutive days.The primary efficacy indicators included the hemoglobin(Hb)improvement rate(RHb)and the traditional Chinese medicine(TCM)syndrome improvement rate(RTCM)at week 4 of treatment.The secondary efficacy indicators encompassed Hb and red blood cell(RBC)count,Karnofsky Performance Status(KPS)score,TCM syndrome score,individual TCM symptom scores,and changes in each of these indicators compared to the baseline period at weeks 2,4,and 6 of treatment.Safety evaluations were conducted at week 4 of treatment.Results A total of 239 patients were enrolled,with 225 cases included in the Full Analysis Set(FAS)(109 in the experimental group vs.116 control group),163 in the Per Protocol Set(PPS)(77 vs.86),and 225 in the Safety Set(SS)(109 vs.116).Baseline characteristics between groups showed no significant differences.Significant differences were observed between the experimental and control groups in RHb at week 4(FAS:49.51%vs.35.24%,P<0.05;PPS:53.25%vs.36.05%,P<0.05)and RTCM at week 4(FAS:61.54%vs.39.62%,P<0.01;PPS:64.94%vs.40.70%,P<0.01).At weeks 2,4,and 6,the experimental group showed greater improvements in Hb and RBC counts than the control group.Additionally,the TCM syndrome scores were lower in the experimental group than in the control group at these time points.Except for week 2 in PPS,the KPS improvement was better in the experimental group than in the control group(P<0.05).The experimental group also demonstrated a greater reduction in scores for individual TCM symptoms such as spiritlessness and weakness,poor appetite and reduced food intake at weeks 4 and 6 compared to the control group(P<0.05,P<0.01).Furthermore,the reduction in vertigo score was more pronounced in the experimental group at week 6(P<0.01).For the score of pale and lusterless complexion,only in the PPS was the reduction from baseline more significant in the experimental group than in the control group at weeks 4 and 6(P<0.05).No significant differences were observed between the experimental and control groups in the incidence of all adverse events or drug-related adverse reactions.Conclusion Shengxuebao Mixture demonstrates significant efficacy in patients with CRA presenting syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood,effectively increasing Hb levels,ameliorating TCM syndromes,alleviating clinical symptoms,and enhancing functional status,with no significant difference in adverse drug reactions compared to the placebo.
