ABSTRACT
Objective:To compare the efficacy of arthroscopic all-inside ligament repair with suture augmentation and ligament reconstruction with tendons in the treatment of chronic ankle instability with poor remnant quality of the anterior talofibular ligament (ATFL) tissue.Methods:A retrospective cohort study was conducted to analyze the clinical data of 37 patients with chronic ankle instability treated at Huashan Hospital Affiliated to Fudan University from January 2018 to August 2020, including 34 males (34 ankles) and 3 females (3 ankles); aged 18-57 years [(32.2±7.2)years]. The time from injury to operation ranged from 3-360 months [48(12, 120)months]. All patients underwent arthroscopic all-inside ankle stabilization surgery, of which 19 underwent ligament repair with suture augmentation (augmented repair group) and 18 underwent traditional ligament reconstruction with allograft/autograft tendons (tendon reconstruction group). The degree of ATFL injury and intra-articular lesions (osteophytes, loose bodies and cartilage damage) were recorded during the operation. The Karlsson scale and Tegner scale were evaluated before operation and at the last follow-up. The number of patients who were able to complete partial weight-bearing/return to normal walking/return to sports postoperatively and the time required were compared between the two groups. Postoperative complications were observed.Results:All patients were followed up for 12-32 months [21(16, 28)months]. There were no significant differences in the degree of ATFL injury and intra-articular lesions (osteophytes, loose bodies and cartilage damage) seen during the operation between the two groups (all P>0.05). At the last follow-up, the Karlsson score in augmented repair group and tendon reconstruction group [95.0(90.0, 98.5)points and 95.0(87.8, 99.3)points] was significantly higher than the preoperative level [65.0(51.0, 75.0)points and 65.0(53.3, 78.0)points] (all P<0.01). At the last follow-up, the Tegner score in augmented repair group and tendon reconstruction group [5.0(3.5, 6.0)points and 5.0(3.3, 6.0)points] were significantly higher than the preoperative level [3.0(2.0, 4.0)points and 2.5(1.3, 4.0)points] (all P<0.01). There were no significant differences in Karlsson score and Tegner score between the two groups (all P>0.05). All patients completed partial weight-bearing after 3.0(2.0, 4.0)weeks in augmented repair group and 4.0(3.5, 6.0)weeks in tendon reconstruction group. All patients returned to normal walking after 8.0(6.0, 9.0)weeks in augmented repair group and 8.0(5.5, 12.0)weeks in tendon reconstruction group. A total of 13 patients (63%) in augmented repair group and 13 patients (72%) in tendon reconstruction group successfully returned to sports postoperatively and the time required was 6.0(3.5, 8.0) months and 6.0(4.5, 12.0)months, respectively. There were no significant differences in the above indicators between the two groups (all P>0.05), but augmented repair group had a trend of faster completion of partial weight-bearing than tendon reconstruction group. There was 1 patient [5%(1/19)] in augmented repair group and 1 patient [6%(1/18)] in tendon reconstruction group who reported feelings of instability during exercise postoperatively ( P>0.05). None of the patients in augmented repair group had limited ankle range-of-motion, not different from 1 patient [6%(1/18)] in tendon reconstruction group ( P>0.05). Conclusion:In the treatment of chronic ankle instability with poor remnant quality of the anterior talofibular ligament (ATFL) tissue, both arthroscopic all-inside ligament repair with suture augmentation and ligament reconstruction with tendons can improve the short-term postoperative ankle function and activity level of the patients, and the former one has advantages such as simple operative procedures and none use of grafts.
ABSTRACT
Objective:To investigate the gaze characteristics of children with autism spectrum disorder (ASD) on dynamic threatening (fear, anger) and non-threatening emotional (sadness, happiness) faces, and to explore the correlation between their eye-tracking data and autism symptomatology scores to provide a basis for the treatment and rehabilitation of children with ASD.Methods:From November 2020 to June 2021, 26 children with ASD and 30 age-and sex-matched normally developing children (typical developmental, TD) who met the enrollment criteria were included, and children with ASD were assessed for symptoms by the childhood autism rating scale (CARS). The SMI-red portable eye-tracking recording system was used to record the eye-movement gaze characteristics of children in both groups during free viewing of dynamic threatening and non-threatening emotional face segments.Statistical processing was performed by SPSS 21.0 software.The independent sample t-test and chi square test were used for the data conforming to the normal distribution, and the non parametric test was used for the data not conforming to the normal distribution, and Pearson correlation analysis was used to analyze the correlation between eye-tracking data and symptomatology scores. Results:The total CARS score of the ASD group was (32.64±7.42). The eye tracking data for children with ASD showed gaze aversion characteristics.Children with ASD spent significantly less time gazing at the eye area of threatening emotional faces in fear (2.41(0.26, 10.65)s) and anger (2.17(0.13, 6.13)s) than children with TD (8.81(2.54, 12.11)s, 5.21(3.80, 12.49)s), with statistically significant differences (fear: Z=-2.252, P<0.05.anger: Z=-2.793, P<0.01). Children with ASD spent significantly less time gazing at the mouth area of all four emotional faces (sad: 3.56(0.44, 7.16)s, fear: 2.68(0.42, 4.78)s, anger: 2.13(0.35, 4.20)s, happiness: 2.93(0.46, 5.71)s) than children with TD (sad: 11.43(6.97, 14.22) s, fear: 6.73(3.65, 10.10)s, anger: 6.86(4.55, 12.33)s, happiness: 11.72(7.22, 14.39)s), with statistically significant differences (sad: Z=-4.502, P<0.01.fear: Z=-3.493, P<0.01.anger: Z=-4.025, P<0.01.happiness: Z=-4.699, P<0.01). Correlation analysis revealed that the time spent gazing at emotional faces in children with ASD was negatively correlated with the total CARS score ( r=-0.476, P<0.05), and further analysis of different emotional faces revealed that the time spent gazing at fearful faces in children with ASD was negatively correlated with the total CARS score ( r=-0.455, P<0.05). Conclusions:Eye tracking in children with ASD show a gaze profile with less gaze time to threatening emotional faces compared with TD children, and the more severe the symptoms in children with ASD, the less gaze time to fearful faces.
ABSTRACT
Objective:To systematically evaluate the efficacy and safety of enteral nutrition via percutaneous endoscopic gastrostomy (PEG) and nasogastric feeding (NGF) in stroke patients.Methods:Databases including PubMed, EMbase, Cochrane Library, Wangfang database (Wangfang data), CNKI and CBM were searched for relevant literature about enteral nutrition via percutaneous gastrostomy in stroke patients. Literature screening, data extraction and quality evaluation of the included study were performed by two independent investigators. RevMan5.3 was used for data analysis.Results:A total of 12 publications were included, of which 7 were randomized controlled trials (RCTs) and 5 were non-RCTs. There were no significant differences in BMI, hemoglobin, serum albumin and mortality. In terms of safety, PEG resulted in effective decreases in the incidence of pneumonia (RR=0.31, 95% CI: 0.18-0.53, P<0.01), hypoproteinemia (RR=0.34, 95% CI: 0.17-0.68, P=0.003) and fluid and electrolyte disorder (RR=0.24, 95% CI: 0.06-0.92, P=0.04) compared with NGF while there was no significant difference in the incidence of abdominal distension, diarrhea and gastrointestinal bleeding .Conclusion:Compared with NGF, enteral nutrition with PEG can effectively reduce the incidence of pneumonia and the risk of infections in stroke patients and can also reduce the incidence of hypoproteinemia and fluid and electrolyte disorder, leading to improved patient outcomes.
ABSTRACT
Objective:To investigate the therapeutic effects of aromatherapy combined with Yin-Yang massage on insomnia in patients. Methods:A total of 120 patients with insomnia who received treatment in Zhoushan Hospital of Traditional Chinese Medicine between September 2017 and December 2019 were included in this study. They were randomly assigned to undergo either aromatherapy (control group, n = 60) or aromatherapy combined with Yin-Yang massage (observation group, n = 60) for 7 days. After treatment, response rate and anxiety status were recorded in each group. Before and after treatment, the scores of Pittsburgh Sleep Quality Index, frequency of taking sleeping pills, and the incidence of adverse reactions were compared between the two groups. Results:Response rate in the observation group was significantly higher than that in the control group [90.00% vs. 73.34%, χ2 = 5.57, P < 0.05]. After treatment, Pittsburgh Sleep Quality Index in the observation group was significantly lower than that in the control group [(9.47 ± 3.65) points vs. (12.45 ± 2.17) points, t = 5.44, P < 0.05]. The frequency of taking sleeping pills in the observation group was significantly lower than that in the control group [(1.19 ± 0.41) times vs. (2.07 ± 0.98) times, t = 6.42, P < 0.05]. There were 0, 3 and 57 cases of severe, moderate and mild anxiety in the observation group, and 5, 18 and 37 cases of severe, moderate and mild anxiety in the control group. There was significant difference in anxiety status between the two groups ( Z = 19.78, P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Aromatherapy combined with Yin-Yang massage can effectively alleviate anxiety in patients with insomnia, improve sleep quality and is highly safe.
ABSTRACT
Objective:To develop a training system for head and neck oncology nurses to improve the emergency response competency to recognize and response to acute and critical medical conditions.Methods:Based on literature review and semi-structured interviews with 12 nurses, two rounds of consultation with 15 head and neck cancer care specialists from 6 Tertiary hospitals using Delphi method were conducted to establish the training system for head and neck oncology nurses.Results:The authority coefficients of experts were 0.87 and 0.89, respectively. The coefficient of variation of each item ranged from 0 to 0.167. The coefficients of concordance ranged from 0.243 to 0.403 ( P<0.01).

In the final training system, training aims included 5 first-level indicators and 16 second-level indicators; training contents included 5 first-level indicators, 16 second-level indicators, and 60 third-level indicators. Conclusions:The authority coefficients and the coefficients of concordance of the experts for the training system were both high. The training system can be applied to improve the emergency response competency of head and neck oncology nurses.
ABSTRACT
Objective:To explore the status of kinesiophobia in patients with heart failure during discharge transition period, and analyze its changing trend and influencing factors.Methods:The189 patients with heart failure treated in Henan Provincial People′s Hospital from February 2020 to April 2021 were conveniently selected as the research objects. The general situation questionnaire, the Tampa Scale for Kinesiophobia Heart, the Self-efficacy for Exercise Scale and the Control Attitudes Scale-Revised were used to investigate the patients 2-3 days before leaving the hospital, 1 month and 4 months after discharge.Results:The score of patients′ kinesiophobia deteriorated slightly from 2-3 days before discharge (48.62 ± 11.26) to 1 month after discharge (49.03 ± 11.24), and decreased with the extension of the transition time to 4 months after discharge (47.86 ± 11.11). The overall trend of improvement was statistically significant ( F = 17.92, P<0.01). The score of perceived disease control also showed the same change pattern, 2-3 days before discharge (27.34 ± 7.40), 1 month after discharge (26.18 ± 7.39), 4 months after discharge (27.76 ± 7.38), the difference was statistically significant ( F = 38.41, P<0.01). The score of the exercise self-efficacy of 4 months after discharge (35.63 ± 11.51) was higher than (34.00 ± 11.88) of 2-3 days before discharge and (34.20 ± 11.69) of 1 month after discharge ( F = 12.33, P<0.01). The generalized estimation equation showed that exercise self-efficacy ( B = -0.255, P<0.01) and perceived disease control ( B = -0.439, P<0.01) were protective factors of kinesiophobia in patients with heart failure. Path analysis showed that perceived disease control could not only directly predict patients′ kinesiophobia ( β = -0.461, P<0.01), but also indirectly affect patients′ kinesiophobia by acting on exercise self-efficacy (mediating effect = -0.21, 95% CI -0.293 - -0.136). The mediating effect accounted for 31% of the total effect. Conclusions:The kinesiophobia, perceived disease control and exercise self-efficacy in patients with heart failure during discharge transition were dynamic. Perceived disease control could not only directly predict patients′ kinesiophobia, but also indirectly affect it by acting on exercise self-efficacy. Nursing staff can develop nursing interventions based on perceived disease control or exercise self-efficacy to reducethe level of kinesiophobia inheart failure patients.
ABSTRACT
Objective:To investigate the safety and feasibility of endoscopic level V lymph node dissection for thyroid cancer.Methods:Two cases undergoing level V lymph node dissection via breast combined with oral approach for papillary thyroid cancer in May. 2021 and Sep.2021 were retrospectively analyzed. The primary thyroid lesions and metastatic lymph nodes were diagnosed pathologically by fine needle aspiration before operation. The routine examination such as ultrasound, CT and laryngoscopy were completed before operation.Results:Both operations were successfully completed under endoscopy. In case 1, one lymph node was found in neck V region, and no metastatic lymph node was found. In case 2, 7 lymph nodes were found in cervical V region. No "shoulder syndrome" encompassing shoulder dysfunction and pain was found in either case.Conclusions:The study on the two cases reveals that level V dissection after the routine operation of endoscopic central and lateral neck dissection via breast combined with oral approach for papillary thyroid cancer is feasible and safe. More cases in further study were needed for to verify the finding.
ABSTRACT
Objective:To analyze and compare the demographic and clinical characteristics of patients with different types of hyperglycemic crisis, so as to provide clinical basis for the prevention and treatment of hyperglycemic crisis.Methods:The data of patients with hyperglycemic crisis in six First-level general hospitals in Chongqing from Jan. 2015 to Dec. 2020 were retrospectively collected and divided into diabetic ketoacidosis (DKA) , hyperglycemic hyperosmolar state (HHS) and diabetic ketoacidosis with hyperglycemic hyperosmotic state (DKA-HHS) . The demographic and clinical characteristics of each group were analyzed by descriptive method.Results:A total of 1668 patients were collected, among whom1388 were DKA, 113 were HHS and 167 were DKA-HHS. The proportion of T2DM in DKA was 90.1%, the proportion of urban residents’ medical insurance, farmers and retirees was higher in the three groups, and the incidence of hyperglycemic crisis in patients above 60 years old was the highest in all age groups. The incidence of DKA and HHS changed little during the six years, but increased significantly in the DKA-HHS group. Shock, disturbance of consciousness, hospitalization expenses and mortality in the DKA-HHS group were higher than those in the other two groups.Conclusions:There are differences in demographic and clinical characteristics among different types of hyperglycemic crisis. Clinically, more attention should be paid to patients above 60 years old and patients with hyperglycemic crisis such as DKA-HHS. Health education and guidance for diabetic patients in high-risk groups should be strengthened in order to reduce the occurrence of diabetic hyperglycemic crisis.
ABSTRACT
Objective: To explore the distribution patterns of cardiometabolic diseases (CMD) in elderly patients with colorectal cancer, and provide a reference for the prevention and treatment of cardiovascular metabolic diseases in these patients. Methods: Clinical data of 3 894 elderly patients with colorectal cancer from January 2008 to March 2018 admitted in the Chinese PLA General Hospital were recruited and the incidence rate of CMD was retrospectively analyzed. The influence factors of elderly patients with colorectal cancer combined with CMD were analyzed by multivariate Logistic regression model. Results: The morbidity rate of CMD in elderly patients with colorectal cancer is 33.4% (1 301/3 894), among them, the morbidity rate of the male was 31.9% (768/2 409), and that of the female was 35.9% (533/1 485). There was not significant difference between these two sex (P=0.074). The morbidity rates of CMD in patients of 65-74 years, 75-84 years and ≥85 years were 30.6% (754/2 462), 37.0% (479/1 294) and 49.3% (68/138), respectively, with significant differences (P<0.001). Multiple Logistic regression analysis revealed that female (OR=1.213, 95%CI: 1.056-1.394), age (75-84 years group: OR=1.344, 95%CI: 1.164-1.552; ≥85 years group: OR=2.345, 95%CI: 1.651-3.331) and body mass index (BMI 18.5-24.9 kg/m(2) group: OR=1.319, 95%CI: 1.065-1.638; ≥25 kg/m(2) group: OR=2.041, 95%CI: 1.627-2.561) were independent risk factors for elderly colorectal cancer patients with CMD. Conclusion: The morbidity rate of CMD in elderly patients with colorectal cancer increases with age and it is urgent to strengthen multidisciplinary cooperation and develop reasonable treatment plans to extend the survival and life quality of these patients.

Objective: To investigate the predictive value of ejection fraction for the postoperative myocardial infarction after coronary endarterectomy (CE) in patients with diffuse coronary artery disease (DCAD). Methods: Patients who underwent cardiac artery bypass graft (CABG) surgery and CE in Beijing Anzhen Hospital affiliated to Capital Medical University from May 2018 to December 2020 were enrolled in this prospective observational study. Baseline features including age, sex and echocardiography parameters were obtained. Left ventricular ejection fraction(EF) was measured by echocardiography. The patients were divided into postoperative myocardial infarction (PMI) group and non-PMI group according to PMI occurrence. Linear regression analysis, logistic regression model, and receiver operating characteristic(ROC) curve were used to analyze the correlation between left ventricular ejection fraction and PMI and the influencing factors. Results: A total of 120 patients were enrolled in the study. There were 32 patients (27%) in the PMI group (male 27(84%), age (62±8)), inferior myocardial infarction occurred in 24 (75%) patients. There were 88 patients (73%) in the non-PMI group (male 70(80%), age (62±8)). EF (55% (49%, 64%) vs. 62% (55%, 67%), P=0.01) was significantly lower in the PMI group than in the non-PMI group. Perioperative TNI, IABP use and length of hospitalization were significantly higher in the PMI group than in the non-PMI group. Multivariate logistic regression showed that lower EF was an independent risk factor of PMI (OR=0.93, 95%CI: 0.89-0.98, P=0.01) after adjusting age, sex and body mass index. ROC curve analysis showed that EF<60% could sufficiently predict the occurrence of PMI (AUC= 0.67, sensitivity 64%, specificity 69%, P=0.01). Linear regression analysis showed that left ventricular end-diastolic diameter (OR=-0.52, 95%CI:-1.13-0.60, P<0.001), graft flow in left anterior descending (OR=-0.20, 95%CI:-0.15-0.01, P=0.02) and history of diabetes (OR=-0.28, 95%CI:-8.25-1.85, P=0.002) were negatively correlated with preoperative EF value. Conclusion: Lower preoperative EF is an independent risk factor for PMI after CABG and CE in DCAD patients, closely related to the left ventricular end-diastolic diameter, graft flow in left anterior descending artery and diabetes mellitus.

ObjectiveTo predict the potential targets and mechanism of Jingfang mixture in the treatment of H1N1 influenza and provide references for clinical application of Jingfang mixture. MethodThe active components and targets of Jingfang mixture against H1N1 influenza were screened out by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP），SwissTargetPrediction， and TargetNet. The targets of H1N1 influenza were obtained from GeneCards，Online Mendelian Inheritance in Man （OMIM）， and DisGeNET and standardized by UniProt KB. The intersection targets were obtained by Venny 2.1.0. The "drug-component-target" network was constructed with Cytoscape 3.2.1 and analyzed for the topological attributes. The intersection targets were uploaded to STRING 11.5 to obtain the protein-protein interaction （PPI） network. Gene Ontology （GO） enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） analysis were carried out by Metascape. Finally，the top active components ranked by degree were docked to the core targets by Autodock vina and visually analyzed by PyMOL. Balb/c female rats were used for experimental verification. Hematoxylin-eosin（HE） staining was used to observe the pathological changes in lung tissues. Enzyme-linked immunosorbent assay（ELISA）was used to detect the levels of tumor necrosis factor-α（TNF-α），interleukin-10（IL-10）， and interleukin-17（IL-17）. Real-time fluorescence-based quantitative polymerase chain reaction（Real-time PCR） and Western blot were used to detect the mRNA and protein expression levels in lung tissues. ResultThere were 144 active components in Jingfang mixture. A total of 421 target genes of Jingfang mixture and 2 956 targets of H1N1 influenza were identified，including 199 common targets. Topological analysis showed that the core components of Jingfang mixture against H1N1 influenza included quercetin，luteolin， and kaempferol，and the core targets included prostaglandin-endoperoxide synthase 2（PTGS2），estrogen receptor alpha（ESR1），inducible nitric oxide synthase 2（iNOS2），peroxisome proliferator-activated receptorγ（PPARγ），and cyclooxygenase-1（PTGS1）. GO enrichment yielded 697 items in biological process （BP） （P<0.01）， 59 items in molecular function （MF）（P<0.01）， and 21 items in cellular component （CC） （P<0.01）. A total of 132 signaling pathways （P<0.01） were obtained by KEGG enrichment analysis， including phosphatidylinositol 3-kinases（PI3K）/protein kinase B（Akt） signaling pathway and mitogen-activated protein kinase（MAPK） signaling pathway，most of which were related to the regulation of immune inflammation. Molecular docking showed that the binding energy of the active components of Jingfang mixture to the core targets was less than -5.0 kcal·mol-1，indicating good binding activity. HE staining showed that the lung tissues were significantly improved after drug intervention，and Real-time PCR and Western blot showed that Jingfang mixture could reduce the mRNA and protein expression of PI3K and Akt in lung tissues. ConclusionJingfang mixture can play an anti-viral effect against the influenza A virus through multiple components，multiple targets， and multiple pathways. The active components quercetin，luteolin， and kaempferol may control the inflammation and regulate immunity on the PI3K/Akt，MAPK， and other signaling pathways by acting on targets such as PTGS2，ESR1，iNOS2，PPARγ， and PTGS1.
ABSTRACT
ObjectiveTo observe the effects of modified Chaihu Shugansan（CHSG） and its disassembled formulas on angiotensin-converting enzyme 2 （ACE2）-angiotensin （Ⅰ-Ⅶ） ［Ang （Ⅰ-Ⅶ）］-mitochondrial assembly receptor （MasR） axis in hyperlipidemic rats with myocardial ischemia and depression， and to explore the underlying mechanism of its prevention and treatment of myocardial ischemia and depression. MethodA total of 108 male SD rats were randomly divided into a normal group， a model group， a modified CHSG group （11.7 g·kg-1）， a Quyu Huatan disassembled formula group （4.05 g·kg-1）， a Shugan Xingqi disassembled formula group （3.15 g·kg-1）， a Jianpi Yangxue disassembled formula group （4.5 g·kg-1）， a fluoxetine group （0.001 8 g·kg-1）， a trimetazidine group （0.005 4 g·kg-1）， and a simvastatin group （0.001 8 g·kg-1）， with 12 rats in each group. The hyperlipidemia model with myocardial ischemia and depression was induced with a high-fat diet combined with injection of isoproterenol （ISO） and chronic unpredictable mild stress （CUMS） in rats in the model group and groups with drug intervention for eight weeks. The rats in each group with drug intervention were treated correspondingly by gavage from the first day of modeling， while those in the normal group and the model group received the same amount of normal saline. The behavioral changes of rats in each group were observed by open field test and forced swimming test. Left ventricular fractional shortening （LVFS） and left ventricular ejection fraction （LVEF） were measured by echocardiography. The serum levels of total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were detected by the enzyme-labeled apparatus. Hematoxylin-eosin （HE） staining was used to observe the histomorphological changes of the heart. The serum levels of angiotensin Ⅱ （AngⅡ）， ACE2， and Ang（Ⅰ-Ⅶ） were detected by enzyme-linked immunosorbent assay （ELISA）. The protein and mRNA expression of ACE2 and MasR in the hippocampus and the heart was detected by real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultCompared with the normal group， the model group showed reduced movement time， distance， and average speed in the central area of the open field （P<0.01）， prolonged immobility time of rats in the forced swimming test （P<0.01）， decreased LVFS and LVEF （P<0.01）， inflammatory exudation and disorderly arranged fiber in heart tissues， elevated serum levels of TC， LDL-C， AngⅡ， ACE2 and Ang（Ⅰ-Ⅶ）， diminished HDL-C （P<0.01）， dwindled mRNA and protein expression of ACE2 in the hippocampus and the heart and MasR in the hippocampus， and up-regulated mRNA and protein expression of MasR in the heart （P<0.01）. Compared with the model group， the modified CHSG group displayed increased movement time， distance， and average speed in the center area of the open field （P<0.01）， shortened immobility time in the forced swimming test （P<0.01）， increased LVFS and LVEF （P<0.01）， relieved heart injury， reduced serum levels of TC， LDL-C， AngⅡ， ACE2， and Ang（Ⅰ-Ⅶ）， elevated level of HDL-C （P<0.01）， up-regulated mRNA and protein expression of ACE2 in the hippocampus and the heart and MasR in the hippocampus， and down-regulated mRNA and protein expression of MasR in the heart （P<0.01）. Each disassembled formula could improve the above indexes to a certain extent （P<0.05， P<0.01）， but the effect of the whole formula was optimal. ConclusionThe modified CHSG and its disassembled formulas have the effects of resisting depression， improving myocardial injury， and reducing blood lipid. Due to the synergistic effects of stasis-resolving/phlegm-eliminating drugs， liver-smoothing/Qi-moving drugs， and spleen-tonifying/blood-nourishing drugs in the formula， the modified CHSG is superior to each disassembled formula in efficacy. Its mechanism may be related to the activation of the ACE2-Ang （Ⅰ-Ⅶ）-MasR axis.
ABSTRACT
ObjectiveTo systematically evaluate the clinical effectiveness and safety of Chinese medicinal injection （CMI） in the treatment of unstable angina pectoris （UAP）. MethodEight databases， i.e.， China National Knowledge Infrastructure （CNKI），VIP，Wanfang Data，CBM，PubMed，EMBASE，The Cochrane Library，and Web of Science were searched for randomized controlled trials （RCT） of conventional treatment combined with CMI （treatment group） versus conventional treatment （CT）（control group）in the treatment of UAP published from database inception to March 31th 2021. Stata 16.0 was used for network Meta-analysis. ResultThirty-nine RCT involving 3 407 patients were included. As revealed by the results of network Meta-analysis， in terms of the total effective rate in angina pectoris improvement， the therapeutic protocols were ranked as Tanreqing injection（TRQI）+CT>Xiangdan injection（XDI）+CT>Ciwujia injection（CWJI）+CT=Shengmai injection（SMI）+CT>Xuesaitong injection（XSTS）+CT>Breviscapine injection（BI）+CT>Shuxuetong injection（SXTI）+CT>Kudiezi injection（KDZI）+CT>Shuxuening injection（SXNI）+CT>Danshen injection （DSI）+CT>Guanxinning injection（GXNI）+CT>Dengzhanxixin injection（DZXXI）+CT>Xueshuantong injection（XSTI）+CT>Gualoupi injection（GLPI）+CT>CT；for the total effective rate in ECG improvement， SXTI+CT>XDI+CT>TRQI+CT>CWJI+CT>XSTI+CT>BI+CT>XSTI+CT>SXNI+CT>GXNI+CT>KDZI+CT>DZXXI+CT>GLPI+CT>CT>SMI+CT；for the adverse reactions， DZXXI+CT>XDI+CT>DSI+CT>BI+CT>SMI+CT>SXNI+CT>CT>GLPI+CT>GXNI+CT>SXTI+CT>KDZI+CT>CWJI+CT；for the reduction of fibrinogen （FIB）， BI+CT>SXTI+CT>XSTI+CT>CT>KDZI+CT；for the reduction of C-reactive protein （CRP）， DSI+CT>DZXXI+CT>XSTI+CT>CT；for the reduction of high-sensitivity C-reactive protein （hs-CRP）， SXNI+CT>KDZI+CT>SXTI+CT>DZXXI+CT>GLPI+CT>TRQI+CT>XSTI+CT>CT. The results of subgroup analyses were consistent with those of the overall Meta-analysis. ConclusionCMI combined with CT can improve angina pectoris and ECG，reduce adverse reactions，and also improve FIB，CRP，and hs-CRP to varying degrees. However，due to the differences in the quality and quantity of CMIs in RCTs，clinical application should be performed based on the specific conditions.
ABSTRACT
ObjectiveTo explore the optimal formula of Maxing Shigantang in regulating epidermal growth factor receptor（EGFR）expression and alleviating airway injury in asthmatic rats and to reveal the underlying mechanism. MethodSD male rats were randomly divided into normal group, model group, dexamethasone group (5×10-4 g·kg-1) and Maxing Shigantang 1∶0.5, 1∶1, 1∶2 groups (group A, B, C, 10 g·kg-1), with 8 rats in each group. The other groups except the normal group received nebulization of 2% acetylcholine chloride and 0.4% histamine phosphate for the modeling of asthma. One hour before modeling， the normal group and the model group were given the same amount of normal saline， and the other groups were given the same amount of corresponding drugs， once a day for 7 days. On the 7th day， the model was established and the incubation period of asthma was recorded. The rats were then immediately anesthetized， and arterial blood and tracheal tissue were collected. Enzyme-linked immunosorbent assay （ELISA） was employed to detect the levels of interleukin-2 （IL-2）， interleukin-4 （IL-4）， and tumor necrosis factor-α （TNF-α） in serum. Pathological sections were prepared for the observation of the pathological changes of tracheal tissues and the ultrastructure of epithelial cells in each group. Terminal-deoxynucleotidyl transferase-mediated nick-end labeling （TUNEL） was adopted to detect epithelial cell apoptosis， and in situ hybridization and Western blot were employed to determine the mRNA and protein levels of epidermal growth factor receptor （EGFR）， respectively. ResultCompared with the model group， groups A， B and C prolonged the incubation period of asthma （P<0.05，P<0.01）. Compared with the control group， the model group showed declined IL-2 level （P<0.01）， risen IL-4 and TNF-α levels （P<0.05，P<0.01）， increased airway pathology score， collagen volume fraction， and airway epithelial cell apoptosis index （P<0.01）， and up-regulated mRNA and protein levels of EGFR in trachea tissue （P<0.01）. Compared with the model group， group A showed increased IL-2 level （P<0.05） and declined IL-4 （P<0.05，P<0.01） level， and group B showed declined IL-4 level （P<0.05）. The level of TNF-α in groups A， B， and C declined compared with that in the model group （P<0.01）. Maxing Shigantang repaired the tracheal tissue to different degrees （P<0.05）. Among the three groups， group A inhibited tracheal fibrosis （P<0.05） and had the most significant effect of repairing the ultrastructural changes of airway epithelial cells. Groups A， B and C all inhibited the apoptosis of airway epithelial cells （P<0.05）. All the three groups inhibited the up-regulation of EGFR mRNA level （P<0.05，P<0.01）， and groups B and C inhibited the up-regulation of EGFR protein level （P<0.05，P<0.01）. ConclusionMaxing Shigantang can inhibit the abnormal changes of airway epithelial structure， alleviate airway injury， and can down-regulate the expression of EGFR in the tracheal tissue of asthma model rats. In this study， the optimal compatibility of Maxing Shigantang to repair airway epithelial injury in asthmatic rats was group A， with the Ephedrae Herba-Armeniacae Semen Amarum-Glycyrrhizae Radix et Rhizoma-Gypsum Fibrosum ratio of 1∶0.5∶4∶1.
ABSTRACT
In the clinical practice of rheumatic immune diseases in traditional Chinese medicine （TCM），it`s still unclear about the dominant diseases and breakthrough points. It`s urgent missions to formulate TCM diagnosis and treatment guidelines widely recognized and integrated by traditional Chinese medicine and Western medicine. In order to clarify the dominant diseases and breakthrough points in rheumatism，China association of Chinese medicine initiated a research group covering experts in the field of rheumatism of traditional Chinese medicine and Western medicine. Based on questionnaire survey and on-site discussion，experts had reached the following consensus. Evidence-based medicine research using modern medical methods and scientific methods should be carried out to provide objective clinical evidences. "Four mutuality" were put forward as the basis for the work of integrated traditional Chinese and Western medicine，that is the mutual communication using the exchangeable context，the mutual explanation using common theories，the mutual certification using common standards，and the mutual integration using common means. Key works should focus on solving refractory rheumatism in the future. In terms of dominant diseases and breakthrough points，this paper introduces 21 breakthrough points in 6 dominant diseases，including rheumatoid arthritis，ankylosing spondylitis，Sjogren's syndrome，hyperuricemia and gout，systemic lupus erythematosus and fibromyalgia syndrome. Advice on this discussion can provide valuable references for developing the treatment scheme of rheumatism with TCM and integrated Chinese and Western medicine and clinical practice and scientific research.
ABSTRACT
The present study investigated the effect of Euphorbiae Pekinensis Radix(EPR) on intestinal flora structure before and after vinegar processing and explored the detoxification mechanism of vinegar-processed EPR. In this study, the extraction efficiency of casbane diterpenes from EPR with different solvents was investigated, and the optimal solvent was selected to enrich these components. After 14 days of intragastric administration of total diterpene extract of EPR and vinegar-processed EPR, 16 S rDNA sequencing technology was used to detect the structural changes of intestinal flora. The flora related to the intestinal toxicity of EPR was screened out based on the results of intestinal pathological damage by correlation analysis. The results showed that Soxhlet extraction with chloroform as extraction solvent could enrich Casbane diterpenes in EPR. As revealed by 16 S rDNA sequencing results, EPR could significantly change the structure of intestinal flora, which could be reversed by vinegar-processing EPR. Some intestinal flora candidates might be related to detoxification of vinegar processing. The correlation analysis of intestinal flora candidates and indexes related to intestinal mucosal injury showed that compared with EPR, vinegar-processed EPR could down-regulate the abundance of some pathogenic bacteria such as Mucispirillum, Bilophila, and Ruminiclostridium, and up-regulated some probiotics such as Enterorhabdus, Ruminococcaceae_UCG-014, Barnesiella, and Candidatus. The intestinal toxicity caused by EPR may be related to the disturbance of intestinal flora, and vinegar-processed EPR can improve intestinal flora disorder by up-regulating the abundance of probiotics and down-regulating the abundance of pathogenic bacteria to remodel the intestinal mucosal barrier and reduce toxicity.

ABSTRACT
Objective:To investigate the expression of zinc finger protein 580 (ZNF580) in oxygen-glucose deprivation (OGD) model of SH-SY5Y cell line and its overexpression on the apoptosis of hypoxic-ischemic neurons and the possible mechanism.Methods:The study was divided into two parts: (1) Human neuroblastoma SH-SY5Y cell line was cultured and divided into the model group and control group. The model group was incubated at 37 ℃ for 6 h in a three-gas incubator of 95% N 2, 5% CO 2, and 0.1% O 2 to establish OGD model, and proteins were extracted at 6, 12, and 24 h after OGD. The expression of ZNF580 was quantified by Western blot. (2) Effects of ZNF580 overexpressed with lentivirus transfection on the apoptosis and cleaved caspase-3 expression: Cells were collected from the control group and model group 24 h after OGD. Overexpressed ZNF580 cells were constructed by lentivirus transfection as the overexpression group and then treated with OGD. Flow cytometry was used to detect the apoptosis rate in the three groups and Western blot was used to detect the expression of cleaved caspase-3. Two independent sample t-test, one-way variance analysis, and LSD- t for pairwise comparison were used for statistical analysis. Results:(1) ZNF580 expression was significantly increased at 6, 12, and 24 h after OGD compared with the control group (1.36±0.05, 2.12±0.07, 1.69±0.05 vs 1.00, LSD- t=9.20, 28.26, and 19.21, all P<0.001). (2) Apoptosis rates of the control, model, and overexpression groups were (1.07±0.56)%, (21.51±1.65)%, and (3.42±0.93)%, respectively, and relative expression levels of cleaved caspase-3 were 1.00, 2.47±0.59, and 1.70±0.25, respectively. Compared with the control group, apoptosis rate and cleaved caspase-3 relative expression level were significantly increased in the model group (LSD- t=21.98 and 8.17, both P=0.001), while the two figures were significantly decreased in the overexpression group when compared with the model group (LSD- t=19.45, P=0.001; LSD- t=4.28, P=0.005). Conclusion:Hypoxia and ischemia could lead to the overexpression of ZNF580, which may reduce the apoptosis of hypoxic-ischemic neurons by inhibiting the expression of cleaved caspase-3 and affecting its enzymatic activation.
ABSTRACT
Objective:To explore the risk factors of autogenous arteriovenous fistula (AVF) aneurysms (AVFAs) in maintenance hemodialysis (MHD) patients.Methods:The patients who used internal arteriovenous fistula (end to side anastomosis) of cephalic vein-radial artery at wrist as vascular access in Hainan Provincial People′s Hospital from June 1 to June 30, 2021 were selected as the research objects. The patients were divided into AVFAs group and non-AVFAs group according to whether AVF formed AVFAs. The clinical data and laboratory examination results between the two groups were compared. Binary logistic regression model was used to analyze the risk factors for the formation of AVFAs.Results:A total of 170 MHD patients were enrolled in this study, including 111 males (65.3%) and 59 females (34.7%), with age of (51.65±12.70) years old and dialysis age of (57.03±49.25) months. There were 33 cases in AVFAs group and 137 cases in non-AVFAs group. The incidence of AVFAs was 19.4%. Compared with non-AVFAs group, the proportion of males ( χ2=4.934, P=0.026) and the levels of serum uric acid ( t=2.547, P=0.012) and serum albumin ( t=2.122, P=0.010) in AVFAs group were higher; The age ( t=-2.210, P=0.028), the proportion of diabetes nephropathy ( χ2=11.788, P=0.001), systolic blood pressure ( t=-1.994, P=0.048) and total cholesterol ( t=-2.174, P=0.031) were lower; The diameter of anastomosis was wider ( Z=-3.224, P=0.001); Mantel-Haenszel chi square test analysis showed that dialysis age ( χ2=53.832, OR=0.518, P<0.001), AVF service time ( χ2=51.355, OR=0.516, P<0.001), and brachial artery blood flow ( χ2=25.315, OR=0.331, P<0.001) were correlated to the formation of AVFAs. The results of multivariate logistic regression analysis showed that males ( OR=10.005, 95% CI 1.875-53.394, P=0.007), longer dialysis age ( OR=1.341, 95% CI 1.104-1.628, P=0.003), longer AVF use time ( OR=1.187, 95% CI 1.002-1.405, P=0.047), higher brachial artery blood flow ( OR=1.002, 95% CI 1.000-1.004, P=0.028) and lower total cholesterol ( OR=0.388, 95% CI 0.172-0.875, P=0.022) were the independent risk factors for the formation of AVFAs. Conclusions:The incidence of AVFAs in MHD patients is 19.4%. Males, long dialysis age, long AVF use time, high brachial artery blood flow and low total cholesterol level are the independent risk factors for the formation of AVFAs.
ABSTRACT
Objective:To explore the association of cardiometabolic index(CMI) and other body fat evaluation indicators [body mass index(BMI), waist circumference(WC), waist to height ratio(WHtR), lipid accumulation index(LAP)] with the prevalence of metabolic syndrome(MS) as well as the predictive value of the above indicators for MS.Methods:A total of 10 140 residents over 40 years old in Guiyang city who participated in the " Epidemiological study on tumor risk of type 2 diabetes patients in China" in 2011 were recruited. The 2005 International Diabetes Federation diagnostic criteria were used to identify MS. Logistic regression was used to analyze the association of CMI and other body fat evaluation indicators with MS. Receiver operating characteristic(ROC) curve was used to evaluate the predictive value and the optimal cut-off point of different indicators. Taking the best cut-off point value of each index as the boundary, the prevalence of MS was evaluated again by Chi square test.Results:The prevalence of MS in the study population was 39.81%(27.23% for men and 44.39% for women). Logistic regression analysis showed that the risk of MS increased with increasing CMI and quartile level of other body fat evaluation indicators in both men and women( P<0.05). The risks of MS in CMI Q4 group were 17.15(95% CI 11.64-25.27) for male and 45.14(95% CI 37.07-54.96) for female compared with Q1 group. In male, the area under curve(AUC) of MS by predicted CMI was 0.761(sensitivity 79.8%, specificity 63.2%, optimal cut-off point 0.71). WC displayed the highest value of AUC among the body fat evaluation indicators. In women, the AUC value of MS predicted by CMI was 0.831(sensitivity 76.8%, specificity 75.7%, optimal cut-off point 0.65), higher than those of BMI and WHtR while lower than those of WC and LAP. Further calculating the prevalence of MS with the best cut-off point value of each index as the boundary, WC was still the best predictor for male, while CMI was only secondary to LAP for women. Conclusion:CMI and other body fat evaluation indicators are significantly associated with MS. CMI could be used to predict MS.
