Objective:To screen the differentially expressed immune-related genes(DEIRGs)in in-stent restenosis(ISR),and to analyze the immune cell infiltration in ISR,and to clarify the mechanism of occurrence and development of ISR.Methods:The mRNA gene expression data of GSE46560 dataset samples were downloaded from the Gene Expression Omnibus(GEO),and divided into ISR group and non-ISR group.The"Limma"package in R software was used to identify the differentially expressed genes(DEGs)which were then intersected with immune-related genes(IRGs)to identify the DEIRGs in ISR;R software was used for Gene Ontology(GO)functional enrichment andalysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis on DEIRGs;the STRING database was used to construct the protein-protein interaction(PPI)network,which was visualized and analyzed for Hub genes by Cytoscape software;the receiver operating characteristic(ROC)curve of the Hub genes were plotted,and the area under the curve(AUC)was calculated and the diagnostic value was evaluated;CIBERSORT software was used to analyze the immune cell infiltration in ISR;Pearson correlation analysis was used to analyze the relationships between the immune cells and the relationships between the immune cells and key genes.Results:A total of 331 DEGs were identified(P<0.05,|log2FC|>1),including 176 upregulated genes and 155 downregulated genes,and 38 DEIRGs were obstained.The GO functional enrichment analysis results showed that the DEIRGs were mainly enriched in biological processes(BP)such as defense response,immune response,and immune system;in cellular components(CC),the DEIRGs were located primarily in the extracellular region and cytoplasmic membrane;and in molecular functions(MF),the DEIRGs were mainly involved in regulating signaling receptor binding and cytokine receptor activity.The KEGG signaling pathway enrichment analysis results indicated that the DEIRGs in ISR were primarily enriched in the phosphatidylinositol 3-kinase/protein kinase B(PI3K-AKT)and transforming growth factor-β(TGF-β)signaling pathways.In the PPI network,CD19 had the highest node among the top 10 Hub genes.Compared with non-ISR group,the expression level of the CD19 gene in the samples in ISR group was increased(P<0.05).The AUC value in the ROC curve of CD19 gene expression was 0.92(P<0.05).The immune cell infiltration analysis results showed that compared with non-ISR group,the infiltration level of T lymphocyte follicular helper(Tfh)cells in the patients in ISR group were increased(P<0.05),the infiltration levels of immature B lymphocytes,CD8+T lymphocytes,naive CD4+T lymphocytes,and M0 macrophages were increased,but the differences were not statistically significant(P>0.05),while the infiltration levels of memory B lymphocytes,activated memory CD4+T lymphocytes,regulatory T cells,resting natural killer(NK)cells,activated NK cells,monocytes,resting mast cells,and neutrophils were decreased,but the differences were not statistically significant(P>0.05).There were positive correlations between Tfh cells and M0 macrophages and resting mast cells(r=0.88,P<0.05;r=0.68,P<0.05),and there were negative correlations between Tfh cells and monocytes and neutrophils(r=-0.49,P<0.05;r=-0.42,P<0.05).Conclusion:CD19 may influence the occurrence and development of ISR by regulating the activation of the PI3K-AKT signaling pathway to affect the Tfh and B lymphocytes.CD19 can serve as a biomarker for the diagnosis of ISR.

OBJECTIVE: To investigate the association between the glucose-to-lymphocyte ratio (GLR) and prognosis of patients with sepsis-associated acute kidney injury (SA-AKI). METHODS: Based on the Medical Information Mart for Intensive Care-IV (MIMIC-IV), SA-AKI patients aged ≥ 18 years were selected. According to the tertiles of GLR, the patients were divided into GLR1 group (GLR ≤ 4.97×10^-9 mmol), GLR2 group (4.97×10^-9 mmol < GLR < 9.75×10^-9 mmol) and GLR3 group (GLR ≥ 9.75×10^-9 mmol). Patients with SA-AKI were divided into survival group and death group according to whether they survived 28 days after admission. The patient's gender, age, vital signs, laboratory test results, comorbidities, sequential organ failure assessment (SOFA), acute physiology score III (APS III) score and treatment measures were extracted from the database. Kaplan-Meier survival analysis was used to make the survival curves of patients with SA-AKI at 28 days, 90 days, 180 days and 1 year. Multivariate Logistic regression analysis model was used to explore the independent risk factors of 28-day mortality in patients with SA-AKI. Receiver operator characteristic curve (ROC curve) was used to analyze the predictive efficacy of GLR for the prognosis of patients with SA-AKI. RESULTS: A total of 1 524 patients with SA-AKI were included, with a median age of 68.28 (58.96, 77.24) years old, including 612 females (40.16%) and 912 males (59.84%). There were 507 patients in the GLR1 group, 509 patients in the GLR2 group and 508 patients in the GLR3 group. There were 1 181 patients in the 28-day survival group and 343 patients in the death group. Grouping according to GLR tertiles showed that with the increase of GLR, the 28-day, 90-day, 180-day and 1-year mortality of SA-AKI patients gradually increased (28-day mortality were 11.64%, 22.00%, 33.86%, respectively; 90-day mortality were 15.98%, 26.72%, 40.55%, respectively; 180-day mortality were 17.16%, 28.29% and 41.73%, and the 1-year mortality were 17.95%, 29.27% and 42.72%, respectively, all P < 0.01). According to 28-day survival status, the GLR of the death group was significantly higher than that of the survival group [×10^-9 mmol: 9.81 (5.75, 20.01) vs. 6.44 (3.64, 10.78), P < 0.01]. Multivariate Logistic regression analysis showed that GLR was an independent risk factor for 28-day mortality in patients with SA-AKI [when GLR was used as a continuous variable: odds ratio (OR) = 1.065, 95% confidence interval (95%CI) was 1.045-1.085, P < 0.001; when GLR was used as a categorical variable, compared with GLR1 group: GLR2 group OR = 1.782, 95%CI was 1.200-2.647, P = 0.004; GLR3 group OR = 2.727, 95%CI was 1.857-4.005, P < 0.001]. ROC curve analysis showed that the area under the ROC curve (AUC) of GLR for predicting 28-day mortality in patients with SA-AKI was 0.674, when the optimal cut-off value was 8.769×10^-9 mmol, the sensitivity was 57.1% and the specificity was 67.1%. The predictive performance was improved when GLR was combined with APS III score and SOFA score, and the AUC was 0.806, the sensitivity was 74.6% and the specificity was 71.4%. CONCLUSIONS GLR is an independent risk factor of 28-day mortality in patients with SA-AKI, and high GLR is associated with poor prognosis in patients with SA-AKI.

【Objective】 To explore the effect of intraoperative cell salvage on allogeneic blood transfusion requirements, coagulation function and electrolytes in postpartum hemorrhage patients. 【Methods】 A study on postpartum hemorrhage patients undergoing cesarean section in the Third Affiliated Hospital of Guangxi Medical University form September 2016 to May 2022 was conducted retrospectively. A total of 137 patients were enrolled and divided into experimental group (n=70) and control group (n=67) according to whether intraoperative cell salvage was used during operation. The blood loss, proportion and volume of allogeneic red blood cells (RBCs) and coagulation component transfusion, hemoglobin (Hb) level, coagulation function, electrolyte, the incidence of complications, proportion of ICU admission, ICU stay and in-hospital stay were compared between the two groups. 【Results】 The proportion of patients receiving allogeneic RBCs in the experimental group and in the control group was 31.4% vs 100.0% (P<0.05). The experimental group also had lower use of plasma (31.4% vs 53.7%, P<0.05). The postoperative 24 h of activated partial thromboplastin time (APTT) and prothrombin time (PT) in the two groups was longer than preoperative, and APTT in the control group did not recover at discharge (P<0.05). Fibrinogen (Fib) decreased postoperative 24 h in the two groups (P<0.05). The blood calcium in the two groups decreased 30 minutes after operation, but the decrease in the experimental group was slight, and two groups did not recover 24 h after operation (P<0.05). There was no statically significant difference in blood loss, volume of allogeneic RBCs and coagulation component transfusion, Hb level, incidence of complications, the proportion of ICU admission, ICU stay and in-hospital stay (P>0.05). 【Conclusion】 This study demonstrated that intraoperative cell salvage could reduce the requirement for allogeneic RBCs without compromising coagulation function in postpartum hemorrhage patients undergoing cesarean section, but the changes of calcium need to be concerned after transfusion.

Background: Patients with acute gouty arthritis experienc severe pain and often have concomitant limited joint movement. High-dose intake of anti-inflammatory analgesics often results in adverse reactions, such as nausea, vomiting, and diarrhea, and might increase the risk of gastrointestinal bleeding. In order to reduce the adverse reactions by oral intake, local use of externally useddrugs with the same active ingredients as the oral intake is an option in clinical practice. However, externally useddrugs take effect slowly and efficacy to reduce painful feelingis unsatisfactory. Therefore, it is demanding to develop a safe and effective treatment plan. In this regard, researchers have put up a hypothesis. The skin of the human body has a dense stratum corneum, which is difficult for externally used drugs to penetrate effectively; if the keratin barrier of the skin around affected joints can be broken without further damaging the skin, externally applied drugs may safely and effectively alleviate the local symptoms of acute gouty arthritis. The nano plum blossom needle is made of a modern new material. The needle body is thin and the diameter of the needle tip is only 300 nm. The needle is used clinically to break through the keratin barrier of the human skin and promote the absorption of external medicine. Therefore, this trial was designed to preliminarily evaluate the safety and effectiveness of using the nano plum blossom needle for the introduction of diclofenac diethylamine emulgel in the treatment of acute gouty arthritis. Methods: A randomized controlled trial including 83 patients with acute gouty arthritis was conducted, who was assigned to three groups, the intervention group, control group 1, and control group 2 in a ratio of 2:2:1, respectively. The nano plum blossom needle was used for the introduction of diclofenac diethylamine emulgel in the intervention group; the nano plum blossom needle was used as a placebo along with the local use of diclofenac diethylamine emulgel in control group 1; and the nano plum blossom needle was used alone in control group 2. The treatments were applied once a day until the pain was completely relieved and the course of treatment lasted up to 7 days. The primary outcome measurement was the visual analog scale for evaluating the degree of pain. The secondary outcome indicators included scoring of the symptoms and signs with comprehensive consideration of the joint skin color, local tenderness, and degree of joint motion, the time and dose of emergency medication usage during trial, and adverse events. Discussion: This trial couldprovide preliminary evidence for evidence-based practice of using nano plum blossom needle transdermal drug delivery technology for diclofenac diethylamine emulgel for the treatment of acute gouty arthritis, and provide a reference for sample size calculation and experimental design of future clinical trials verifying the effectiveness and safety of such a technical scheme in a larger target population. Registration information This study has been registered in the China Clinical Trial Registry Centerwith the registration code of ChiCTR-IOR-17012154.

OBJECTIVE： To investigate the effects of new mode of medical orders evaluation according to disease classification. METHODS： Totally 16 kinds of common diseases were selected from each department of our hospital. Each 10 electronic medical records of each disease were randomly selected from 160 patients in the hospital information system from Jan. 1 to Dec. 31， 2016. The rationality of 10 720 medical orders were evaluated retrospectively during hospitalization. Statistical analysis was made on the relevant indicators such as unsuitable usage and dosage， the proportion of auxiliary drugs and unsuitable indications in medical orders of irrational drug use， and a new mode of prescription comment was established according to the classification of diseases. 9 862 medical orders of same disease types were collected after the implementation （from Apr.-May， 2017） of new mode and intervene to evaluate the irrational rate of them so as to evaluate the effects of new mode. RESULTS： In the samples in 2016， a total of 751 medical orders of irrational drug use were evaluated， the most of them were unsuitable usage and dosage （414 items， 55.12％）， especially in the intracerebral hemorrhage diseases （69 items， 16.67％）； under this kind of disease， most of irrational drug use was excessive dosage of single dosing （31 items， 44.92％）. The top three disease types in the list of the ratio of adjuvant drug cost in total drug cost were surgery for renal tumors （39.43％）， acute cerebral infarction （non-surgery） （37.03％） and intervertebral disc herniation surgery （35.26％）. 70 medical orders of irrational drug use were unsuitable indications （9.32％）. After the application of evaluation mode according to classification of disease types and intervene， the irrational rate of medical orders decreased from 7.00％ （751/10 720） before evaluation to 2.95％ （291/9 862）after evaluation， decreasing by 57.86％. CONCLUSIONS： The application of evaluation mode according to classification of disease types can achieve good results in controlling the irrational rate of medical orders and contribute to rational drug use in clinic.

OBJECTIVE:To explore the medication rules of TCM complex formulas for anti-experimental liver injury. METH-ODS:Usingexperimental liver injuryTCM complex preparationsprotection effectas themes,related literatures about medi-cation rules of TCM complex formulas for anti-experimental liver injury in CJFT,Wanfang database and VIP database were re-trieved,and general information,distribution,use frequency and co-occurrence frequency of single herbal medicine were descrip-tively analyzed. K-means clustering model and Apriori in SPSS Modeler were adopted for cluster analysis(clustering side and im-portance)and correlation analysis in medicines with top 10 use frequency. RESULTS:498 related literatures were retrieved,and 70 valid literatures were involved totally,including 51 TCM complex formulas and 111 Chinese herbal medicines. It was mainly drug for clearing heat,restoring vital energy and blood circulation. Drugs for clearing heat were most widely used(34 varieties),drugs for restoring vital energy showed the highest use frequency,with 63 times(25.82%);Prunella vulgaris had the highest frequency in single herbal medicines(accounting for 25.49%);and P. vulgaris-Salvia miltiorrhiza had the highest co-occurrence frequency in drug pairs. 5 clustering sides were obtained in clustering analysis,which were P. vulgaris-S. miltiorrhiza-Angelica sinensis- Glycyr-rhiza uralensis,Astragalus membranaceus-A. sinensis-Hedyotis diffusa,Artemisia scoparia-Curcuma wenyujin-Plygonum cuspida-tum,P. vulgaris-S. miltiorrhiza-A. scoparia,Schisandra chinensis-G. uralensis. Importance prediction showed,S. chinensis was the most important and P. cuspidatum was the least important. 13 drug pair rules were obtained from correlation analysis,and both sup-port and confidence degrees were low. CONCLUSIONS:The TCM complex formulas for anti-experimental liver injury are mainly based on drugs for clearing heat and restoring vital energy,while the compatibility is varied,and correlation degree is relatively low.

Objective To evaluate the efficacy of the anterior approach to quadratus lumborum block in each abdominal and back region.Methods Twelve healthy volunteers of both sexes,aged 18-45 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,with body mass index of 18-30 kg/m2,were enrolled in the study.Quadratus lumborum block was performed via the anterior approach under the guidance of ultrasound with 0.375％ ropivacaine 20 ml.The block was assessed by cold stimulation (ice cake) in each abdominal and back region (the right side of the body was divided into 15 regions using the anatomical landmarks on the body surface).The positive condition in each region was recorded at 30 min after administration.Results The region in which the positive rate ≤ 5％ was 0.The regions in which the positive rate ＞5％-20％ were 1 and 13 regions.The regions in which the positive rate ＞20％-50％ were 2,3 and 4 regions.The regions in which the positive rate ＞50％-70％ were 6,7 and 10 regions.The regions in which the positive rate ＞70％-＜95％ were 5,14 and 15 regions.The regions in which the positive rate ≥95％ were 8,9,11 and 12 regions.Conclusion The anterior approach to quadratus lumborum block is effective in the middle-lower region of the anterior abdominal wall on the blocked side.

Objective To explore the value of MR T2 mapping imaging in evaluation of the effection of Zhitong-Jiangu recipes in treatment of cartilage injury in osteoarthritis.Methods The models of osteoarthritis in the knee of New Zealand white rabbits were made with intra-articular injection of papain.Totally 48 New Zealand white rabbits were randomly divided into normal control group,model control group,glucosamine hydrochloride treatment group and Zhitong-Jiangu recipes treatment group.MR T2 mapping was performed on the knee and the content of MMP-1 in articular cartilage was analyzed with immunohistochemistry 4 weeks after treatment.The differences of T2 value and MMP-1 content of articular cartilage among the four groups were compared.The correlation among the different intervention methods,MMP-1 content of articular cartilage and the T2 value of articular cartilage were analyzed.Results T2 value of articular cartilage in the model control group was significantly higher than that in the other three groups (all P＜0.01),and there was no significant difference of T2 value among the other three groups.The MMP-1 content of articular cartilage in glucosamine hydrochloride treatment group and Zhitong-Jiangu recipes treatment group was lower than that in model control group (both P＜0.05),and was higher than that in normal control group (both P＜0.05).There was no significant difference between the two groups.The relationship between MMP-1 content and T2 value of articular cartilage was nonlinear.With the increase of MMP-1 content,T2 value first increased slowly and then increased rapidly (P＜0.05).Conclusion MR T2 mapping imaging is helpful to evaluating the efficacy of Zhitong-Jiangu recipes in treatment of cartilage injury in osteoarthritis in rabbit models.The relationship between MMP-1 content and T2 value of articular cartilage may be nonlinear.

Objective The advantages of the treating allergic rhinitis (AR) by sphenopalatine ganglion stimulation with acupuncture were evaluated.Methods Databases including CBMDisk, CNKI, WanFang, VIP, Cochrane Library, PubMed, ProQuest, ChiCTR, ISRCTN, ClinicalTrials.gov and CENTRAL were searched from the beginning of database established to Jan 2015. All issues from Jan 2004 to Jan 2015 published onjournals Chinese Acupuncture & Moxibustion,Shanghai Journal of Acupuncture and Moxibustion, Acupuncture Research,Journal of Clinical Acupuncture and Moxibustion,Chinese Journal of Integrated Traditional and Western Medicine and Chinese Journal of Otorhinolaryngology in Integrative Medicine were searched by hand at meantime. All data were extracted based on the inclusive and exclusive criteria which was pre-designed, the Revman5.3 was applied for meta-analysis, and the studies qualities were analyzed by grade score.Results 118 articles were collected, 7 studies that involving 1 230 patients met the inclusive criteria. The result indicated that the sphenopalatine ganglion stimulation with acupuncture as the main treatment of AR showed the better total response rate compared to conventional drugs, theOR(95%CI) was 3.22(1.81 - 5.75); however the change of total symptom score had no statistical significant difference, the MD(95%CI) was 0.69 (-0.56 - 1.93), the change of IgE had no statistical significant difference,theSMD(95%CI) was -0.07 (-0.97 - 0.83).Conclusion The main treatment on AR by sphenopalatine ganglion stimulation with acupuncture may has better efficacy than western medicine. But due to the methodological biases existed in most studies, future high-quality RCTs were needed to be included into Meta-analysis to test today’s study conclusion.

OBJECTIVETo compare the effects of acupuncture on sphenopalatine ganglion and acupuncture on the common acupoints for life quality of patients with allergic rhinitis(AR).

METHODSEighty patients with AR,who were in accord with the inclusive criteria,were randomly divided into an observation group and a control group,40 cases in each one. Acupuncture on sphenopalatine ganglion was used in the observation group. The needle was inserted into the gap between zygoma and mandibular coronoid process about 55 mm. Acupuncture was adopted on the main acupoints,Yingxiang(LI 20),Yintang(GV 29) or Fengchi(GB 20) in the control group. The course was four weeks. Follow-up was applied one month after treatment. Rhinoconjunctivitis quality of life questionnaire (RQLQ),rhinitis symptoms scale and visual analogue scale(VAS) were evaluated at different time points before and after treatment,and follow-up was implemented to know the recurrence situation,satisfactory degree and adverse reaction.

RESULTS(1) RQLQ scores:along with treatment,the RQLQ scores were gradually apparently decreased in the two groups(<0.01),and the reducing trend from the first week to the second week of the observation group was more obvious than that of the control group. The differences of the RQLQ scores at all timepoints after treatment between the two groups were not statistically significant(all>0.05). The interaction of the time factor and the group factor had statistical significance(<0.01). (2) Rhinitis symptoms scores:along with treatment,the scores presented decreasing trend in the two groups(<0.01). The scores of the two groups after treatment and the interaction of the time factor and the group factor were not statistically different(both>0.05). (3)VAS scores:the VAS scores after treatment were lower than those before treatment(both<0.01). The differences before and after treatment were statistically significant(<0.01),with more change in the observation group(<0.05). (4)There was no statistical significance about the number of recurrence days between the two groups(>0.05). (5) Above 80 percent patients were content with the therapeutic method in each group,with no statistical difference(>0.05). (6)The method of the observation group spent less time. (7) Two patients with light adverse reaction came up in the observation group,but no special treatment was needed.

CONCLUSIONSAcupuncture on sphenopalatine ganglion acquires more obvious short-term effect than conventional acupuncture. It spends less time to relieve symptoms and improves life quality.
