ObjectiveTo observe the effectiveness and safety of modified Taohong Siwu Decoction （桃红四物汤） for patients of chronic heart failure with lower limb deep vein thrombosis in the chronic stage of blood stasis syndrome. MethodsA total of 120 patients of chronic heart failure with lower limb deep vein thrombosis in chronic stage of blood stasis syndrome were randomly divided into 60 cases each in control group and observation group. Both groups were given basic treatment of western medicine， and the observation group was additionally given modified Taohong Siwu Decoction （桃红四物汤） for oral administration， one dose per day. The treatment course for both groups lasted for 4 weeks. The total effective rate and the incidence of adverse reactions were compared between the two groups after treatment. Cardiac function indexes including left ventricular ejection fraction （LVEF）， and left ventricular end-systolic internal diameter （LVESd）， left ventricular end-diastolic internal diameter （LVEDd）， serological indexes including N-terminal natriuretic natriuretic peptide precursor （NT-proBNP）， high sensitivity C-reactive protein （hs-CRP） and vascular endothelial growth factor （VEGF）， score of traditional Chinese medicine （TCM） symptom including chest pain， swelling of the affected limb， fixed tenderness， and bruising， haemodynamics indicators including high cut whole blood viscosity， low cut whole blood viscosity， and erythrocyte pressure， and coagulation indices including activated partial thromboplastin time （APTT）， plasminogen time （PT）， and fibrinogen （FIB） levels were compared before and after treatment. ResultsDuring the study， 3 cases were excluded and 2 cases lost follow-up in the observation group， while 2 cases were excluded and 3 cases lost follow-up in the control group. A total of 110 patients completed the trial， 55 cases in each of the two groups. The total effective rate in the observation group was 92.73% （51/55）， which was significantly higher than that of the control group， 78.18% （43/55， P＜0.05）. Compared within group before treatment， LVEF， APTT and PT levels increased， LVESd， LVEDd， NT-proBNP， hs-CRP， VEGF， high cut whole blood viscosity， low cut whole blood viscosity， erythrocyte pressure volume and FIB levels decreased， chest pain， swelling of the affected limbs， stationary pressure pain and bruising score decreased in both groups after treatment， and the improvement of all above indexes was better in the observation group than that in control group （P＜0.05 or P＜0.01）. The incidence of adverse reactions was 7.27% （4/55） in the observation group and 21.82% （12/55） in the control group， and the incidence of adverse reactions in the observation group was significantly lower than that in the control group （P＜0.05）. ConclusionModified Taohong Siwu Decoction （桃红四物汤） as adjuvant treatment for patients of chronic heart failure with lower limb deep vein thrombosis in the chronic stage of blood stasis syndrome showed better clinical effectiveness when compared with western basic treatment， which can improve the clinical symptoms， cardiac function， haemodynamics， and coagulation， with good safety.

Objective To investigate the risk warning indicators for postoperative admission to the intensive care unit(ICU)in patients with ureteral calculi combined with urinary sepsis.Methods The clinical data of 288 patients with ureteral calculi combined with sepsis diagnosed and treated in the First Hospital of Fujian Medical University from October 2020 to October 2023 were retrospectively analyzed,including gender,age,length of hospitalization,clinical conditions[body mass index(BMI),diabetes,hypertension,systemic inflammatory response syndrome(SIRS)score,sequential organ failure assessment(SOFA),quick SOFA(qSOFA)],general indicators[white blood cell count(WBC),body temperature,respiratory rate,heart rate],and degree of hydronephrosis.The patients were divided into two groups:those admitted to the ICU and those not admitted to the ICU after the operation.The differences in the above clinical data between the two groups of patients were compared.Univariate and multivariate Logistic regression analyses were used to screen out the risk factors affecting the admission of patients with ureteral calculi combined with sepsis to the ICU,and the receiver operator characteristic curve(ROC curve)of the subjects was plotted to analyze the predictive efficacy of each risk factor on the admission of patients to the ICU.Results Finally,263 patients were enrolled,out of which 43 patients(16.35％)were admitted to ICU,and all patients recovered and were discharged.Compared with the group not admitted to the ICU,the length of hospitalization in the group admitted to the ICU was significantly longer(days:8.42±1.50 vs.5.51±1.19),and the proportion of patients with diabetes mellitus,the SIRS score,the SOFA score,the qSOFA score,the proportion of patients with body temperatures>39.4℃ or<35.8℃,respiratory rate>20 beats/min,heart rate>90 bpm,and the proportion of patients with severe hydronephrosis were all significantly higher[diabetes mellitus:44.19％(19/43)vs.27.27％(60/220),SIRS scores:3(2,4)vs.2(1,3),SOFA score:7(5,9)vs.4(3,6),qSOFA score:2(1,3)vs.0(0,1),and body temperature>39.4℃ or<35.8℃:44.19％(19/43)vs.25.91％(57/220),respiratory rate>20 beats/min:37.21％(16/43)vs.21.82％(48/220),heart rate>90 bpm:48.84％(21/43)vs.29.55％(65/220),severe hydronephrosis:72.09％(31/43)vs.17.28％(38/220),all P<0.05].Multivariate Logistic regression analyses showed that SOFA score,qSOFA score,and degree of hydronephrosis were independent risk factors for admission to the ICU,with odds ratios(OR)of 1.486,3.546,and 4.423,respectively,along with 95％confidence intervals(95％CI)of 1.146-1.925,1.949-6.543,and 2.355-8.305,P values were 0.003,<0.001,<0.001.ROC analysis showed that,the AUC of SOFA score was the largest of 0.824,the AUC of qSOFA was similar to that of SOFA(0.802 vs.0.824),and the specificity of hydronephrosis was the highest of 82.7％.The joint diagnosis of qSOFA and the degree of hydronephrosis were combined to establish a joint prediction model.The goodness-of-fit test was performed using the Hosmer-Lemeshow test,revealingχ2=8.942,P=0.257>0.05.This indicated that the predictive model of the joint index was well calibrated,and the ROC curves showed improved diagnostic efficacy of the joint index and were superior to that of the SOFA score(AUC:0.889 vs.0.824,P=0.047).Conclusion The qSOFA and the degree of hydronephrosis were independent risk factors for postoperative ICU admission in patients with ureteral calculi combined with urinary sepsis,and the combined diagnosis of the two may provide a good early warning of the risk of ICU admission in such patients.

Objective To investigate the predictive value of combined serum levels of N-terminal pro-B-type natriuretic peptide(NT-proBNP)and lipoprotein(a)[Lp(a)]and coagulation function indicators for occurrence of deep venous thrombosis(DVT)in elderly patients with chronic heart failure(CHF).Methods A total of 230 elderly CHF patients admitted in Hengshui People's Hos-pital from January 25 to December 25,2022 were enrolled,and divided into a DVT group(76 ca-ses)and a non-DVT group(154 cases)based on the presence of DVT or not.And another 100 healthy individuals taking physical examination during the same period were included and served as the control group.The general information,clinical data,and coagulation indicators of each group were collected.Serum NT-proBNP and Lp(a)levels were measured with ELISA.Logistic regression analysis was used to determine the independent risk factors,and ROC curve was used to determine the predictive values of single and combined detection.Results The incidence of lower limb arteriosclerosis was significantly higher in the DVT group than that in the non-DVT group(P＜0.05),but there were no statistical differences in other data(P＞0.05).Platelet count and LDL in DVT group were higher than those in non-DVT group,and HDL was lower than those in non-DVT group(P＜0.05).The DVT group had notably shorter activated partial throm-boplastin time(aPTT),prothrombin time(PT)and thrombin time(TT),and remarkably higher FIB,D-dimer,NT-proBNP and Lp(a)levels when compared with the non-DVT group(P＜0.05).Logistic regression analysis showed that HDL,aPTT,FIB,D-dimer,NT-proBNP and Lp(a)were independent risk factors for DVT in elderly CHF patients(P＜0.05,P＜0.01).The obtained lo-gistic regression model was:Logit(P)=0.933X3+0.744X8+0.812X11+0.681X12+0.774X13+0.684X14.The combined regression model had an AUC value of 0.948(95％CI:0.918-0.977),a sensitivity of 89.47％and a specificity of 89.61％.Conclusion NT-proBNP,Lp(a),and coagula-tion function indicators are independent risk factors for DVT in elderly CHF patients,and com-bined detection has high predictive value.

Objective:To understand the genome sequence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and spike protein variations during different epidemic periods in Wuxi City.Methods:Nucleic acid was extracted from the nasopharyngeal swab samples of six local cases of coronavirus disease 2019 (COVID-19) (from January to February, 2020) and 13 imported cases of COVID-19 (from March to September, 2021) in Wuxi City, and the whole genome was amplified to construct the sequencing library. The second-generation sequencer was used for sequencing. The CLC Genomics Workbench (21 version) software was used to analyze the offline data with NC_045512.2 as the reference strain, and MEGA 7.0 software was used to construct the phylogenetic tree.Identification of type was conducted by Nextstrain typing method and phylogenetic assignment of named global outbreak lineages (Pangolin) typing method.Results:There were five subtypes in Nextstrain and seven subtypes in Pangolin of the nineteen patients with COVID-19. Compared with NC_045512.2, the median nucleotide mutation sites were 29 (range 0 to 42) and amino acid mutation sites were 20 (range 0 to 34). The six local and 13 imported cases had no common nucleotide mutation sites and were in different evolutionary branches. The sequences of the six local cases were highly homologous with the reference strain sequences (NC_045512.2) at the early stage of the pandemic, and the evolutionary distance was close to that of the reference strain. The 13 imported cases were obviously divided into three evolutionary branches (Alpha, Beta, Delta variant).The four Beta variants shared eight amino acid mutation sites in spike protein, and the two Alpha variants shared eight amino acid mutation sites in spike protein, and the seven Delta variants shared five amino acid mutation sites in spike protein.Conclusions:New mutations of SARS-CoV-2 are constantly emerging during the epidemic. The increase of the nucleotide sites number may result in the change of spike protein amino acid. Therefore, the whole-genome sequencing analysis plays an important role in the accurate tracing of epidemic origin and adjustment of prevention and control measures.

AIM: To analyze the chemical ingredients of Qingxin-zishen prescription decoction (QZPD) and predict its main pharmacodynamic substances and mechanism in the prevention and treatment of menopause syndrome (MPS) with the help of high performance liquid chromatography-quadrupole-time of flight mass spectrometry (HPLC-Q-TOF/MS) combined with network pharmacology. METHODS: The chemical ingredients of QZPD were identified after analyzing the retention time, exact mass, secondary mass spectrometry fragmentation and other information obtained from HPLC-Q-TOF/MS and comparing them with the established chemical ingredients database and the literatures. The targets of ingredients in QZPD were predicted by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and SwissTargetPrediction database. The disease targets of MPS were obtained through Online Mendelian Inheritance in Man (OMIM) and GeneCards Database. Gene ontology (GO) function enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of potential targets were analyzed with the Metascape database. Cytoscape 3.7.2 software was used to construct the network of active components-key targets-pathways. AutoDockTools 4.2.5 software was applied in the molecular docking verification between the key active components and key targets. RESULTS: A total of 83 components were identified in QZPD and 847 drug targets were predicted. After intersection them with 3 050 disease targets, 395 common targets were obtained. After network topology analysis, 74 key targets were obtained, involving mitogen-activated protein kinase (MAPK), phosphatidylinositol-3 kinase/protein kinase B (PI3K/Akt), transforming growth factor-β (TGF-β) and other signaling pathways. Molecular docking analysis results indicated that 23 key active components, such as berberine, epiberberine, coptisine, geissoschizine methyl ether, liensinine, norcoclaurine, palmatine, quercetin, and luteolin, had good binding activity with several of the key targets. CONCLUSION: This study preliminarily identifies the potential effective chemical ingredients of QZPD, predicts its targets in the prevention and treatment of MPS, which provides supporting information for the further study of the pharmacodynamic substances and mechanisms of QZPD.

Sepsis-associated encephalopathy(SAE)is a common complication with high mortality in patients with sepsis, but its pathogenesis is not clear, and there is no recognized diagnostic criteria and specific treatment.Intestinal tract plays an engine-like role in the occurrence and development of sepsis.The destruction of intestinal barrier and the disorder of intestinal microorganisms can affect the outcome of sepsis, in which gut microbiome affect the pathophysiology of intestine and brain through " the microbiome-gut-brain axis" (MGBA), and "gut microbiome-mitochondrial crosstalk" explains its role at the organelle level.The gut microbiome disorder exists in SAE animal model, while fecal bacteria transplantation can improve the symptoms and prognosis, suggesting that the exploration of gut microbiome may be of certain significance to understand the mechanism of SAE and explore its treatment.Here we review from three aspects: the gut microbiome, MGBA and the role of gut microbiome in SAE.

Objective     To identify the risk factors for postoperative recurrence of peripheral solid small-nodule lung cancer (PSSNLC) (T≤2 cm), and to explore the effects of surgery types on prognosis. Methods     We extracted data from Western China Lung Cancer Database (WCLCD), a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University, and Surveillance, Epidemiology, and End Results (SEER)  database for peripheral solid small-nodule lung cancer patients (T≤2 cm N0M0, stageⅠ) who underwent surgery between 2005 and 2016. We used univariable and multivariable logistic regression to analyze risk factors for recurrence of PSSNLC. We applied propensity-score matching to compare the long-term results of segmentectomy and lobectomy, as well as the survival of patients from WCLCD and SEER. We finally included 4 800 patients with PSSNLC (T≤2 cm N0M0)(WCLCD: SEER=354∶4 446). We matched 103 segmentectomies and 350 lobectomies in T≤1 cm, and 280 segmentectomies and 1 067 lobectomies in 1 cm

Objective:To investigate the clinical effacies of endoscopic midline and paramedian supracerebellar infratentorial (SCIT) approaches during resection of pineal tumors.Methods:The clinical data of 4 patients with pineal tumors resected via SCIT approach under neuroendoscope in our hospital from December 2017 to March 2019 were analyzed retrospectively. All patients underwent MR imaging plain and enhanced scans before operation. The tumors were resected via SCIT approach under general anesthesia in lateral subduction position (three were via paramedian SCIT approach and one was via midline SCIT approach). The patients were followed up for 3-12 months and the brain MR imaging was reexamined.Results:The tumors were completely resected in 4 patients. Two patients were confirmed to have mixed germ cell tumors, one was confirmed to have seminoma, and the other one was confirmed to have mature teratoma by postoperative pathology. One achieved good recovery after surgery. Two were treated with whole brain and spinal cord radiotherapy, the original lesion in one patient recurred 4 months after resection and systemic chemotherapy was given, and so far, no recurrence was noted; and the other one achieved good recovery. One did not receive chemoradiotherapy due to economic reasons and relapsed 4 months after surgery.Conclusion:It is safe and effective to resect the tumors in pineal region via midline and paramedian SCIT approaches with neuroendoscopy; the best approach should be selected according to the blood supply, size and location of the lesions.

Objective     To explore the effect of standardized use of antibiotics on clinical indicators after thoracic surgery, such as pulmonary infection rate, incision infection rate, average length of hospital stay and total hospitalization cost. Methods     We selected 468 patients (an observation group) who were hospitalized and received thoracic surgery from August to October 2011, 3 months after the implementation of the preventive antibiotics use protocol for thoracic surgery in West China Hospital, Sichuan University, and selected 343 patients (a control group) in the same period of the previous year (from August to October 2010). There were 326 males and 142 females with a mean age of 52.0±15.5 years in the observation group, and 251 males and 92 females with a mean age of 51.4±15.9 years in the control group. The level of antibiotic use, medication time, antibiotics cost, postoperative incision infection, incidence of pulmonary infection, postoperative hospital stay and total hospitalization cost were compared between the two groups. Results     Compared with the control group, the time for preventive use of antibiotics was significantly shorter in the observation group (3.6±2.4 d vs. 6.1±3.1 d, P=0.020) and the total cost of antibiotic use significantly reduced (1 230.0±2 151.0 yuan vs. 2 252.0±1 764.0 yuan, P<0.001). There was no significant difference between the two groups in hospitalization cost (36 345.0±13 320.0 yuan vs. 35 821.0±11 991.0 yuan, P=0.566), postoperative hospital stay (10.6±8.4 d vs. 10.7±5.3 d, P=0.390), the incidence of postoperative wound infection or postoperative pulmonary infection (1.5% vs. 2.3%, P=0.430; 19.2% vs. 22.2%, P=0.330). Conclusion     The standardized use of antibiotics in thoracic surgery does not cause   postoperative pulmonary infection and incision infection, and has no negative impact on clinical indicators. Significantly reducing the level of antibiotics use may have a positive effect on reducing medication time, in-hospital infection and the incidence of drug-resistant strains.
