Objective:To evaluate the efficacy and safety of Qingxuan Zhike granules in improving cough symptoms and shortening the course of influenza (wind-heat invading lung) in children.Methods:In this multicenter, randomized, controlled clinical trial, a total of 240 outpatient influenza patients from 7 hospitals, including the First Affiliated Hospital of Yunnan University of Traditional Chinese Medicine, from April 2023 to December 2023 were collected.The subjects were randomly divided into the control group and the experimental group via SAS software using the block randomization method.The differences between two groups were compared with t test, corrected t test and χ2 test.Subjects in the control group were given Oseltamivir phosphate granules, orally, twice a day (weight ≤15 kg, 30 mg/time; weight >15-23 kg, 45 mg/time; weight >23-40 kg, 60 mg/time; weight >40 kg, 75 mg/time; age≥13 years, 75 mg/time).In addition to Oseltamivir phosphate granules, subjects in the experimental group were also given Qingxuan Zhike granules, orally, 3 times a day (1-3 years old, 1/2 bag each time; >3-6 years old, 3/4 bag each time; >6-14 years old, 1 bag each time).After 5 days of treatment, the medication was suspended for 2 days.The effect of cough, antipyretic effect, clinical recovery rate, clinical recovery time, Canadian Acute Respiratory Illness and Flu Scale (CARIFS) score, traditional Chinese medicine (TCM) syndrome effect, complication rate, and adverse reactions were evaluated between the two groups. Results:Finally, 232 cases were included in the study, including 115 cases in the experimental group and 117 cases in the control group.Before and after treatment, there were no significant difference in CARIFS cough score between the experimental group and the control group (all P>0.05).After treatment, the change in CARIFS cough score in the experimental group [(-1.00±0.91) scores]was significantly higher than that in the control group [(-0.75±0.98) scores] ( t=-1.995, P=0.047).After treatment, the change in TCM syndrome cough score in the experimental group [(-1.69±1.51) scores] was significantly higher than that in the control group [(-0.97±1.63) scores] ( t′=-0.035, P=0.001).The time of complete regression of fever in the experimental group [(44.82±22.72) h] was shorter than that in the control group [(51.35±27.07) h], and the difference between the two groups was statistically significant ( t=-1.966, P=0.050).The fever score showed that the area under the curve between the CARIFS symptom fever score and time in the experimental group was 4.40±2.42, while that in the control group was 5.12±2.44, and the difference between the two groups was statistically significant ( t=-2.252, P=0.025).The clinical recovery rate was 93.91%(108/115) in the experimental group and 92.31%(108/117) in the control group, and there was no significant difference between the two groups ( χ2=0.233, P>0.05).The clinical recovery time in the experimental group [(2.93±1.21) d] was shorter than that in the control group [(3.29±1.15) d], and the difference between the two groups was statistically significant ( t=-2.279, P=0.024).After treatment, there was a significant difference in TCM syndrome score variation between the experimental group [(-12.00±4.13) scores] and the control group [(-10.85±4.31) scores] ( t′=-2.067, P=0.040).No complication occurred in both groups, and there was no significant difference in the incidence of adverse events between the two groups ( χ2=1.299, P>0.05). Conclusions:Qingxuan Zhike granules combined with Oseltamivir phosphate can effectively improve the cough symptoms associated with influenza in children, shorten the time and course of fever, and improve the TCM syndrome score; thus, they are safe in clinical application.

Objective:To understand the current clinical practice status of evidence on blood glucose management in ICU patients with insulin intravenous infusion, analyze barriers and formulate action strategies, so as to provide reference for the translation of evidence into clinical practice.Methods:Based on the clinical evidence application model of the Joanna Briggs Institute (JBI) Evidence-Based Health Care Center, clinical nursing problems were identified, literature search, evaluating and summarizing evidence were carried out, and review indicators and methods were developed. From July to August 2023, convenience sampling was used to select 42 nurses and 80 patients with insulin intravenous infusion from the comprehensive ICU of Wuxi Second People's Hospital as participants for baseline review. Barriers were analyzed and change strategies were developed based on baseline review results.Results:A total of 16 pieces of evidence were introduced regarding blood glucose management in ICU patients with insulin intravenous infusion. Nineteen review indicators were formulated, of which 13 had a compliance rate of less than 60%. Analysis identified 18 barriers and 13 facilitators. Sixteen change strategies were developed based on barriers and facilitators.Conclusions:There is still a significant gap between the evidence of ICU insulin intravenous infusion blood glucose management and clinical practice. Evidence-based practice programs should be constructed based on intervention strategies to effectively promote the application of evidence in clinical practice.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

The establishment of an intelligent audit system for hospital medical insurance is crucial for standardizing irrational practices and curbing the unwarranted escalation of medical insurance costs. A tertiary hospital has developed comprehensive prescription review rules in terms of indications, nutritional risk assessments, pain score evaluations, drug sensitivity test results, and target patient populations. When using medical insurance funds for settlement, both systematic and manual reviews are conducted, and three-level intervention measures such as " prompt, review, and interception" are implemented based on prescription issues. After the system was put into use, the hospital′s in-process information system supervision mode shifted from the previous focus on prompts to focus on audits. The medical insurance intelligent audit system provided timely prompts and interventions, and the number of unreasonable medical insurance prescriptions and deductions from medical insurance sampling prescriptions significantly decreased ( P<0.001), while the number of medical insurance medication prescription audits increased ( P<0.001). The application of the intelligent medical insurance medication audit system has improved the efficiency of prescription auditing and ensured the rationality of the use of medical insurance funds.

Objectives:To analyze the clinical features of microscopic polyangiitis (MPA), and observe the clinical outcomes of different pathological types.Methods:The clinical data of 61 patients with MPA in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2010 to December 2019 were analyzed retrospectively. According to age, the patients were divided into ≥ 60 years old group (46 cases) and<60 years old group (15 cases). According to the initial serum creatinine, the patients were divided into ≥ 500 μmol/L group (18 cases) and<500 μmol/L group (43 cases). The basic data and laboratory examination results of the patients were recorded, and the disease activity was evaluated by Birmingham systemic vasculitis activity score (BVAS). Twenty-three patients with complete pathological data were pathologically classified and followed up to assess their clinical outcomes. The progression to end-stage renal disease (ESRD) or death was defined as the endpoint.Results:Ferritin in ≥60 years old group was significantly higher than that in<60 years old group: 452 (289, 792) μg/L vs. 210 (119, 451) μg/L, and there was statistical difference ( P<0.05). The fever rate, hemoglobin and platelets in creatinine ≥ 500 μmol/L group were significantly lower than those in creatinine<500 μmol/L group: 3/18 vs. 48.8% (21/43), 77.5 (62.8, 86.0) g/L vs. 85.0 (77.0, 104.0) g/L and 192 (147, 234) × 10 9/L vs. 257 (208, 365) × 10 9/L, the gastrointestinal involvement and BVAS in creatinine ≥ 500 μmol/L group were significantly higher than those in creatinine<500 μmol/L group: 16/18 vs. 25.6% (11/43) and 20.0 (16.0, 23.3) scores vs. 15.0 (12.0, 19.0) scores, and there were statistical differences ( P<0.05 or<0.01). Pearson correlation analysis result showed that BVAS was positively correlated with creatinine ( r = 0.42, P<0.01), negatively correlated with hemoglobin ( r = -0.42, P<0.01), but it had no correlation with erythrocyte sedimentation rate and platelets ( r = 0.05 and 0.04, P>0.05). Among the 23 patients with completed the clinical outcome statistics, endpoint events occurred in 5 of 6 patients with crescent renal pathology, and in 7 of 12 patients with severe renal interstitial injury. Kaplan-Meier survival curve analysis result showed that the average survival time in ESRD MPA patients was significantly shorter than that in non ESRD MPA patients (41.2 months vs. 63.5 months), and there was statistical difference ( χ2 = 0.48, P = 0.028). Conclusions:The clinical manifestations of elderly MPA patients are similar to those of young MPA patients. Creatinine≥500 μmol/L or anemia at initial onset indicate higher vasculitis activity in MPA. The prognosis of MPA patients with pathological manifestations of crescent or severe interstitial injury is poor, and the survival rate of ESRD is lower than that of non ESRD patients.

Objective To investigate chromosomal abnormalities in fetuses with conotruncal defects(CTD).Methods From January 2013 to February 2017,107 fetuses (singleton pregnancy) prenatally diagnosed as CTD in Beijing Anzhen Hospital were enrolled.Umbilical cord specimens of these fetuses were collected after termination of pregnancy and analyzed by low coverage whole gene sequencing to detect chromosomal aneuploidy and copy number variations.Types of chromosomal abnormalities in these cases were analyzed.Chi-square test was used for statistical analysis.Results Twenty-two cases (21％,22/107) were identified with chromosomal abnormalities.The most common seen chromosomal abnormalities were found in those with interrupted aortic arch (2/2),followed by those with tetralogy of Fallot and pulmonary atresia/stenosis accompanied with ventricular septal defect (28％,12/43).No chromosomal abnormalities were detected in fetuses with aortopulmonary septal defect (0/2).Differences were shown in the detection rates of chromosomal abnormalities among different types of CTD (x2=12.744,P=0.026).Among the 22 fetuses with chromosomal abnormalities,there were seven with abnormal aneuploidy (three trisomy-13s,two trisomy-18s,one trisomy-21 and one 45,X) and 15 with pathogenic copy number variations [11 cases with 22q11.2 microdeletion syndrome,two with 17p12p11.2 microdeletion (Smith-Magenis syndrome),one with 8p23.3p21.3 microduplication and one with 2p23.1p25.2 microdeletion].Of the 15 cases with pathogenic copy number variations,12 segments of microdeletion/microduplications were de novo and one was paternally inherited,while the causes of the other two were not clear because their parents refused chromosomal testing.Conclusions Fetal CTD are likely to be accompanied with aneuploidy abnormalities and chromosome microdeletions/microduplications and the detection rate of chromosomal abnormalities varied with the type of CTD.Microdeletion and microduplication,especially de novo microdeletions/duplications,are the common chromosomal abnormalities.Chromosome analysis is recommended for fetuses prenatally diagnosed with CTD.

Objective To study the apoptosis of human colorectal cancer HT-29 cells induced by Aralia elata Seem leaf total saponin (ETS) and its effects on the expression of relevant proteins. Methods MTT assay was used to detect the proliferation of human colorectal cancer HT-29 cells cultivated with different concentrations (6.25, 12.5, 25, 50, 100, 200 mg/kg) of ETS. Hoechst33258 staining and laser confocal imaging were used to detect the apoptotic cells. Morphological changes were observed. The expressions of Bcl-2 and Bax were detected by immuno-histochemistry. Results ETS could induce apoptosis of HT-29 cells and apoptosis was in a dose-dependent manner in a certain range. ETS could decrease the expression of Bcl-2 and increase the expression of Bax in HT-29 cells (P<0.05, P<0.01), showing a significant dose-effect relationship. Conclusion ETS can induce the apoptosis of HT-29 cells, and the mechanism may be related to reducing the expression of Bcl-2 and increasing the expression of Bax.

Objective To explore optimal suctioning negative pressure in endoscopic nasobiliary drainage (ENBD) after endoscopic retrograde cholangiopan-creatography (ERCP). Methods A total of 131 patients with extrahepatic bile duct stones complicated with infection, who were treated by ENBD after ERCP, were randomly divided into two groups according to intubation dates from September 2013 to December 2014. The patients of two groups were treated with the same medical and nursing care. The pressure of low suctioning negative pressure group (61 cases) was -1--5 kPa and the pressure of high suctioning negative pressure group (70 cases) was -5--8 kPa. The conditions of biliary bleeding, drainage volume, drainage tube obstruction and patient comfort in two groups were compared. Results There were 4 cases of bile occult blood in low suctioning negative pressure group and 9 cases in high suctioning negative pressure group (P>0. 05). The daily biliary drainage volume in low suctioning negative pressure group was (349. 79 ± 108. 26) ml, which was more than that in high suctioning negative pressure group (t=6. 76,P<0. 01). There were 8 cases of drainage tube obstruction in low suctioning negative pressure group, which was less than that of 25 cases in high suctioning negative pressure group (χ2 =8. 83,P<0. 01). There were 2 cases of postoperative vomiting and 4 cases of xiphoid under pain in low suctioning negative pressure group, which were less than those in high suctioning negative pressure group (χ2 =17. 27,3. 89;P<0. 05). Conclusions The optimal suctioning negative pressure in ENBD after ERCP is -1--5 kPa. It can be used in clinical nursing care in order to improve patient comfort and keep the drainage tube unobstructed.
