ABSTRACT

BACKGROUND@#The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results.@*OBJECTIVE@#To identify factors and their impact on the treatment effect of acupuncture in different outcomes.@*METHODS@#Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects.@*RESULTS@#The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01).@*CONCLUSIONS@#High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

ABSTRACT

Radiation enteritis (RE) is a common syndrome in the radiotherapy of abdominal and pelvic malignant tumors, heavy influencing living quality, but no specific clinical regimens are available. Long oil (LO) is composed of the fat components from cuttlebone, safflower, walnut oil and rapeseed oil and has been clinically used for wound healing. In this study, oral LO was applied for the prevention and treatment of RE and the mechanisms were explored. Animal experiments were approved by the Ethics Committee of the Beijing Institute of Radiation Medicine, Academy of Military Medical Sciences, and the experiments were conducted in accordance with relevant guidelines and regulations. An RE mouse model was established after single whole abdominal γ-ray radiation of 13 Gy. LO (8 mL·kg-1) was intragastrically administered to the mice 1 h pre-radiation. Compared to the models, the mice of the LO group had more regenerated intestinal crypts and longer villus on day 3.5, and remarkable increase in the abundance of gut microbiota on day 7, especially the amounts of probiotics including Eubacterium and Lactobacillus. Moreover, the mice of the LO group showed longer total movement distance, shorter immobility time, and higher speed than the model mice on day 7. On day 14, the mice of the LO group showed the high descending of proinflammatory factors including tumor necrosis factor-α and interleukin-6, close to the normal levels. Therefore, oral LO can alleviate the inflamed syndromes of RE and improve the repair of damaged intestinal tissues. Moreover, the mice of the LO group had highly low permeability of intestinal mucosa according to the fluorescence labeling experiment, which was close to the normal level. Oral LO can protect intestine mucosa and prevent RE by modification of the intestinal microenvironment, alleviation of the inflammatory response, and promotion of tissue repair.

ABSTRACT

Pulmonary fibrosis is an interstitial lung disease characterized by inflammatory injury and tissue structure destruction. Currently, there is a lack of effective therapeutic drugs for pulmonary fibrosis, and the mechanism is still unknown. Therefore, it is urgent to seek new targets for effective drugs. In pulmonary fibrosis, the level of autotaxin (ATX) in bronchoalveolar lavage fluid increases and stimulates the production of lysophosphatidic acid (LPA). The involvement of LPA receptors in activating a variety of G-protein-mediated signal transduction pathways leads to a range of related physiological effects, including pro-inflammatory signaling in epithelial cells, activation of transforming growth factor signaling, and stimulation of fibroblast accumulation. LPA receptor antagonists and ATX inhibitors have been concerned as new targets for pulmonary fiber therapy, and currently related drugs have entered clinical trials. In this paper, the pathophysiological effects of LPA and ATX in pulmonary fibrosis disease and related drug development progress were reviewed to provide reference information of new drug development for pulmonary fibrosis based on the ATX-LPA axis.

ABSTRACT

BACKGROUND@#The optimal apolipoprotein or lipid measures for identifying statin-treated patients with coronary artery disease (CAD) at residual cardiovascular risk remain controversial. This study aimed to compare the predictive powers of apolipoprotein B (apoB), non-high-density lipoprotein cholesterol (non-HDL-C), low-density lipoprotein cholesterol (LDL-C), apoB/apolipoprotein A-1 (apoA-1) and non-HDL-C/HDL-C for myocardial infarction (MI) in CAD patients treated with statins in the setting of secondary prevention.@*METHODS@#The study included 9191 statin-treated CAD patients with a five-year median follow-up. All measures were analyzed as continuous variables and concordance/discordance groups by medians. The hazard ratio (HR) with 95% CI was estimated by Cox proportional hazards regression. Patients were classified by the clinical presentation of CAD for further analysis.@*RESULTS@#The high-apoB-low-LDL-C and the high-non-HDL-C-low-LDL-C categories yielded HR of 1.40 (95% CI: 1.04-1.88) and 1.51 (95% CI: 1.07-2.13) for MI, respectively, whereas discordant high LDL-C with low apoB or non-HDL-C was not associated with the risk of MI. No association of MI with discordant apoB versus non-HDL-C, apoB/apoA-1 versus apoB, non-HDL-C/HDL-C versus non-HDL-C, or apoB/apoA-1 versus non-HDL-C/HDL-C was observed. Similar patterns were found in patients with acute coronary syndrome. In contrast, no association was observed between any concordance/discordance category and the risk of MI in patients with chronic coronary syndrome.@*CONCLUSIONS@#ApoB and non-HDL-C better predict MI in statin-treated CAD patients than LDL-C, especially in patients with acute coronary syndrome. ApoB/apoA-1 and non-HDL-C/HDL-C show no superiority to apoB and non-HDL-C for predicting MI.

ABSTRACT

ObjectiveTo compare the effects of programmed intermittent epidural bolus (PIEB) and continuous epidural infusion (CEI) on enhanced recovery after cesarean section. MethodsTotally 120 women scheduled to undergo elective cesarean section under combined spinal and epidural anesthesia, aged 18-45 years, with single fetus, full-term pregnancy (≥37 weeks), ASA grade II or III, were recruited, with 60 cases in each group. At the end of the surgery, after a similar epidural loading dose, patients were randomLy assigned to receive either PIEB (6 mL·h-1 beginning 30 minutes after the loading dose) or CEI (6 mL·h-1, beginning immediately after the loading dose) for the maintenance of analgesia with 0.1% ropivacaine. At 2, 6, 12, 24 and 36 h postoperatively, VAS score was used to evaluate the composite pain, and Bromage Score was used to evaluate the degree of lower extremity motor block. The time to first flatus, time to first ambulation and the satisfaction scores were also recorded. ResultsThe VAS scores at 12, 24 and 36 h postoperatively and the lower extremity motor block scores at 6, 12 and 24 h postoperatively in the PIEB group were significantly lower than those in the CEI group (P < 0.01). The epidural analgesic dosage was less in the PIEB group than that of the CEI group (P=0.002). The time to first flatus and time to first ambulation were significantly shorter than those in the CEI group (P < 0.05). The satisfaction scores were significantly higher in the PIEB group than in the CEI group (P < 0.05). There was no significant difference in the first urination time after urinary catheter removal and the length of hospital stay between the two groups (P > 0.05). ConclusionCompared with CEI, PIEB provides better postoperative analgesia, less motor block scores, lower epidural analgesic dosage, shorter the time to first flatus and defecation and time to first ambulation, and greater patient satisfaction, which is more consistent with the ERAS concept of analgesia.

ABSTRACT

Persistent neurogenesis exists in the subventricular zone (SVZ) of the ventricles and the subgranular zone (SGZ) of the dentate gyrus of the hippocampus in the adult mammalian brain. Adult endogenous neurogenesis not only plays an important role in the normal brain function, but also has important significance in the repair and treatment of brain injury or brain diseases. This article reviews the process of adult endogenous neurogenesis and its application in the repair of traumatic brain injury (TBI) or ischemic stroke, and discusses the strategies of activating adult endogenous neurogenesis to repair brain injury and its practical significance in promoting functional recovery after brain injury.

ABSTRACT

As an indicator that measures the degree of implementation of intervention measures during the implementation process, fidelity could be used for monitoring and quality evaluation of the completion degree of intervention measures, and plays an important role in improving the degree of intervention implementation and clarifying the factors that affect intervention implementation. This article aims to introduce the connotation and significance, measurement, control, and current application status of fidelity, as well as the current application status of fidelity in acupuncture-moxibustion clinical research and its inspiration for future research. Meanwhile, based on the existing evaluation tool development methods of fidelity and the characteristics of acupuncture-moxibustion clinical research, a preliminary fidelity evaluation framework is proposed. Introducing fidelity into acupuncture-moxibustion clinical research could improve the implementation quality and compliance of acupuncture-moxibustion in clinical research, increase the credibility and effectiveness of clinical research results, and promote the transformation of acupuncture-moxibustion experience into easily learnable and promotable treatment plans.

ABSTRACT

We used network pharmacology to predict the mechanism in the treatment of rheumatoid arthritis (RA) via modified Gan Cao Fu Zi Decoction (GCFZ), and validated the results of the analysis and explored the pharmacodynamic effects of GCFZ through animal experiments. Firstly, TCMID, SymMap, HERB, STITCH and GEO databases were utilized to obtain the target genes of GCFZ for the treatment of RA, which yielded a total of 1 250 differentially expressed genes for RA, 534 genes for GCFZ targets and 83 intersecting genes. Then functional enrichment analysis of the intersecting genes was performed through GO and KEGG databases, and the results revealed that GCFZ and its active ingredients mainly functioned through cytokine pathways, where chemokine signaling pathway and tumor necrosis factor (TNF) signaling pathway were enriched with a high number of genes. Cytoscape 3.8.0 software was used to construct the drug-target-disease network and screen key proteins, which included TNF, C-X-C chemokine ligand 8 (CXCL8), C-X-C chemokine ligand 10 (CXCL10), C-C chemokine ligand 5 (CCL5), C-X-C chemokine ligand 2 (CXCL2) and C-X-C chemokine receptor type 4 (CXCR4). The molecular docking technology was used to confirm the binding ability of the main active ingredients of GCFZ to the core proteins. Additionally, the therapeutic effects of GCFZ in low (4 g·kg-1), medium (8 g·kg-1) and high (16 g·kg-1) dose groups were investigated by constructing the collagen-induced arthritis (CIA) rat model. X-ray imaging approach, HE staining and Safranin O-Fast Green staining showed that GCFZ treatment significantly improved bone destruction, synovial hyperplasia and cartilage damage in CIA rats, while immunofluorescence results showed that GCFZ treatment could regulate the expression of TNF, CXCL8 and CCL5. In summary, our results indicate that GCFZ contains a variety of small molecule pharmacodynamic substances, which can exert therapeutic effects via multiple targets and pathways, and obviously reduce the symptoms of arthritis in CIA rats. This animal experiment of our research was approved by the Experimental Animal Management and Ethics Committee of Bengbu Medical College.

ABSTRACT

OBJECTIVES@#To evaluate the report quality, methodological quality and evidence quality of the systematic reviews and meta-analyses (SRs/MAs) of acupuncture for in vitro fertilization-embryo transfer (IVF-ET).@*METHODS@#The SRs/MAs of acupuncture for IVF-ET were searched electronically from databases of CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, Cochrane Library, from inception of each database to September 27th, 2022. Two reviewers independently screened the literature and extracted the data. Using PRISMA statement, the AMSTAR 2 scale and the GRADE system, the report quality, methodological quality and evidence quality of the included SRs/MAs were assessed.@*RESULTS@#A total of 28 SRs/MAs were included, with PRISMA scores ranging from 8.5 points to 27 points. The problems of report quality focused on protocol and registration, retrieval, risk of bias in studies, additional analysis, limitations and funding. The methodological quality of included studies was generally low, reflecting on items 2, 3, 7, 10, 12 and 16. A total of 85 outcome indexes were included in the GRADE system for evidence grade evaluation. Most of the evidences were low or very low in quality. The reasons for the downgrade were related to study limitations, inconsistency, imprecision and publication bias.@*CONCLUSIONS@#Acupuncture therapy improves the outcomes of IVF-ET, but the methodological quality and evidence quality of related SRs/MAs are low. It is recommended to conduct more high-quality studies in the future to provide more reliable evidences.

ABSTRACT

Endoplasmic reticulum is one of the most important organelles in maintaining cellular homeo⁃ stasis, mainly involved in intracellular lipid synthesis, protein folding and calcium ion homeostasis. Trau⁃ ma, ischemia and hypoxia and other pathological changes can cause protein folding dysfunction in the en⁃ doplasmic reticulum, triggering endoplasmic reticulum stress (ERS). Spinal cord injury (SCI) is a com⁃ mon traumatic disease with anextremely high disability rate, which seriously affects the quality of life. There is no safe and effective clinical methods so far. Investigations have shown that ERS is one of the important pathological changes leading to cell death and neuronal dysfunction after SCI, and is closely as⁃ sociated with signaling pathways such as apoptosis, autophagy, and inflammation in neurons after SCI; however, the molecular mechanisms between ERS and SCI have not yet been thoroughly investigated. A deeper understanding and exploration of the potential molecular mechanisms associated with ERS and SCI may be the future SCI therapeutics. In this paper, we first summarized the relationship between the chan⁃ ges of ERS⁃related genes and the pathological process of SCI, Then the interrelationships between ERS and the apoptosis, inflammation, and autophagy signaling pathways after SCI were analyzed, starting from the three main modes of regulation, including unfolded protein response (UPR), endoplasmic reticulum⁃ associated degradation (ERAD), and endoplasmic reticulophagy (ER⁃phagy),Finally, we summarize the relevant drugs and application prospects of targeting ERS for SCI in recent years, which may provide a theoretical basis for targeting the ERS pathway for SCI and provide some ideas and insights for the de⁃ velopment of future therapeutic strategies after SCI.

ABSTRACT

Aim To investigate whether resveratrol (Resveratrol, Res) induces cardiomyocyte protection by increasing intracellular zinc ion and its possible signal mechanism. Methods H9c2 cells were routinely cultured and 2-deoxyglucose (2-DG) was used to establish an endoplasmic reticulum stress (ERS) model. The experiment was randomly divided into control group, 2-DG group, Res +2-DG group, TPEN + Res + 2-DG group and 3-MA + Res +2-DG group. Cell viability was detected by MTT and CCK-8; the expression levels of ERS molecular chaperone proteins glucose-regulated protein 78 (GRP78), glucose-regulated protein 94 (GRP94) and autophagy proteins LC3 II / I, p62 and p-AMPK were detected by Western blot; the expression of LC3 protein was measured by cellular immunofluorescence; the mitochondrial membrane potential (Aijjm) and the intracellular zinc ion level were measured by laser scanning confocal microscope. Results Compared with the control group, 2-DG reduced cell activity and resveratrol inhibited the changes caused by 2-DG, which was reversed by zinc chelator TPEN. 2-DG increased GRP78 and GRP94 expression and resveratrol inhibited the protein changes caused by 2-DG, which was reversed by TPEN. 2-DG increased the expression of LC3 II / I, p-AMPK and decreased the expression of p62, and resveratrol promoted the effect of 2-DG. 2-DG increased the fluorescence intensity of LC3, and resveratrol enhanced the effect of 2-DG, which was reversed by TPEN and 3-MA. 2-DG reduced the red fluorescence intensity of mitochondrial TMRE and green fluorescence intensity of intracellular zinc ions, and resveratrol inhibited these changes caused by 2-DG, which was also reversed by TPEN and 3-MA. The above differences were all statistically significant (P < 0. 05). Conclusion Resveratrol increases intracellular zinc to promote ERS-induced autophagy and prevent the mPTP opening in H9c2 cardiac cells.

ABSTRACT

Objective: To investigate the clinicopathological characteristics, pathological diagnosis and prognosis of diffuse midline glioma (DMG) with H3K27 alteration in adults. Methods: Twenty cases of H3K27-altered adult DMG diagnosed in the First Affiliated Hospital of Nanjing Medical University were enrolled from 2017 to 2022. All cases were evaluated by clinical and imaging presentations, HE, immunohistochemical staining and molecular genetics; and the relevant literature was reviewed. Results: The ratio of male to female was 1∶1, and the median age was 53 years (range from 25 to 74 years); the tumors were located in the brainstem (3/20, 15%) and non-brainstem (17/20, 85%; three in thoracolumbar spinal cord and one in pineal region). The clinical manifestations were non-specific, mostly dizziness, headache, blurred vision, memory loss, low back pain, limb sensation and/or movement disorders, etc. Microscopically, the tumors showed infiltrative growth, with WHO grade 2 (3 cases), grade 3 (12 cases), and grade 4 (5 cases). The tumors showed astrocytoma-like and oligdendroglioma-like, pilocytic astrocytoma-like and epithelioid-like patterns. Immunohistochemically, the tumor cells were positive for GFAP, Olig2 and H3K27M, and H3K27me3 expression was variably lost. ATRX expression was lost in four cases, p53 was strongly positive in 11 cases. Ki-67 index was about 5%-70%. Molecular genetics showed p. k27m mutation in exon 1 of H3F3A gene in 20 cases; BRAF mutation in two cases: V600E and L597Q mutation in one case each. Follow up intervals ranged from 1 to 58 months, and the survival time for brainstem (6.0 months) and non-brainstem (30.4 months) tumors was significantly different (P<0.05). Conclusions: DMG with H3K27 alteration is uncommonly found in adults, mostly occurs in non-brainstem, and can present in adults of all ages. Owing to the wide histomorphologic features, mainly astrocytic differentiation, routine detection of H3K27me3 in midline glioma is recommended. Molecular testing should be performed on any suspected cases to avoid missed diagnosis. Concomitant BRAF L597Q mutation and PPM1D mutation are novel findings. The overall prognosis of this tumor is poor, with tumors located in the brainstem showing worse outcome.

ABSTRACT

Objective: To understand the status of autism spectrum disorder (ASD) cohort studies and explore the feasibility of constructing ASD disease-specific cohorts based on real-world data (RWD). Methods: ASD cohort studies published by December 2022 were collected by literature retrieval from major Chinese and English databases. And the characteristics of the cohort were summarized. Results: A total of 1 702 ASD cohort studies were included, and only 60 (3.53%) were from China. A total of 163 ASD-related cohorts were screened, of which 55.83% were birth cohorts, 28.22% were ASD-specific cohorts, and 4.91% were ASD high-risk cohorts. Most cohorts used RWD such as hospital registries or conducted community-based field surveys to obtain participant information and identified patients with ASD by scales or clinical diagnoses. The contents of the studies included ASD incidence and prognostic risk factors, ASD comorbidity patterns and the impact of ASD on self-health and their offspring's health. Conclusions: ASD cohort studies in developed countries have been in the advanced stage, while the Chinese studies are still in their infancy. RWD provides the data basis for ASD-specific cohort construction and offers new opportunities for research, but work such as case validation is still needed to ensure the scientific nature of cohort construction.

ABSTRACT

Simiao Yong'an Decoction is a classic prescription for treating gangrene. Modern medical evidence has proven that Si-miao Yong'an Decoction has therapeutic effects on atherosclerosis(AS), vascular occlusion angeitides, and hypertension, while its pharmacodynamic mechanism remains unclear. The evidence of network pharmacology, molecular docking, literature review, and our previous study suggests that luteolin and kaempferol are two major flavonoids in Simiao Yong'an Decoction and can inhibit macrophage inflammation and exert anti-AS effects. However, due to lack of the metabolism studies in vivo, little is known about the metabolic characteristics of luteolin and kaempferol. This study employed ultra-performance liquid chromatography coupled with linear ion trap-Orbitrap mass spectrometry(UHPLC-LTQ-Orbitrap MS/MS) and relevant software to identify the metabolites and metabolic pathways of luteolin and kaempferol in rat plasma, urine, and feces, after oral administration of luteolin and kaempferol, respectively. After the administration of luteolin, 10, 11, and 3 metabolites of luteolin were detected in the plasma, urine, and feces, respectively. After the administration of kaempferol, 9, 3, and 1 metabolites of kaempferol were detected in the plasma, urine, and feces, respectively. The metabolic pathways mainly involved methylation, glucuronidation, and sulfation. This study enriches the knowledge about the pharmacological mechanism of luteolin and kaempferol and supplies a reference for revealing the metabolic process of other flavonoids in Simiao Yong'an Decoction, which is of great significance for elucidating the pharmacological effects and effective substances of this decoction in vivo.

ABSTRACT

The chemical components of Huanglian Decoction were identified by ultra-performance liquid chromatography-quadrupole-time-of-flight-tandem mass spectrometry(UPLC-Q-TOF-MS/MS) technology. The gradient elution was conducted in Agilent ZORBAX Extend-C_(18) column(2.1 mm×100 mm, 1.8 μm) with the mobile phase of 0.1% formic acid aqueous solution(A)-acetonitrile(B) at a flow rate of 0.3 mL·min~(-1) and the column temperature of 35 ℃. The MS adopted the positive and negative ion mode of electrospray ionization(ESI), and the MS data were collected under the scanning range of m/z 100-1 500. Through high-resolution MS data analysis, combined with literature comparison and confirmation of reference substances, this paper identified 134 chemical components in Huanglian Decoction, including 12 alkaloids, 23 flavonoids, 22 terpenes and saponins, 12 phenols, 7 coumarins, 12 amino acids, 23 organic acids, and 23 other compounds, and the medicinal sources of the compounds were ascribed. Based on the previous studies, 7 components were selected as the index components. Combined with the network pharmacology research and analysis me-thods, the protein and protein interaction(PPI) network information of the intersection targets was obtained through the STRING 11.0 database, and 20 core targets of efficacy were screened out. In this study, UPLC-Q-TOF-MS/MS technology was successfully used to comprehensively analyze and identify the chemical components of Huanglian Decoction, and the core targets of its efficacy were discussed in combination with network pharmacology, which laid the foundation for clarifying the material basis and quality control of Huanglian Decoction.

ABSTRACT

Objective: To investigate whether the contralateral normal external auditory canal (EAC) skin graft can maintain the ear canal health after EAC reconstruction in unilateral congenital aural atresia (CAA) cases. Methods: A Zelen design randomized controlled study was used to collect unilateral CAA patients for EAC reconstruction prospectively (clinical trial registration number: ChiCTR2000032103). The patients were randomly divided into the control group and the trial group. The trial group used the contralateral normal EAC skin graft group (transplant part of the contralateral normal EAC skin to repair the atresia side for unilateral CAA patients), the control group all used scalp blade thick skin. We observed the EAC health and hearing results of the two groups after EAC reconstruction. Results: A total of 13 cases were enrolled from July 2020 to August 2021. There were eight patients in the trial group, including six males and two females, with an average age of 22.3 years (14-36 years). There were two patients with CAA on the left and six patients on the right. The average follow-up time was 8.8 months (4-14 months). There were five patients in the control group, all cases were male with an average age of 16.2 years (12-20 years). There were four patients with CAA on the left and one patient on the right. The average follow-up time was 7.0 months (2-14 months). In the trial group, eight cases of reconstructed EAC epithelium were healthy, one patient had cicatricial stenosis of EAC opening and lateralization of the tympanic membrane. The other patient had cicatricial stenosis of reconstructed EAC, this case also had scar hyperplasia of the contralateral EAC opening but recovered after soft packing and triamcinolone acetonide injection treatment. The healthy side EAC of the rest trial group had no scarring stenosis or local bone hyperplasia during long-term follow-up. In the control group, one patient was lost to follow-up and the other four patients had dry ears of reconstructed EAC, but easily to form crusts and needed to be cleaned repeatedly, one patient had lateralization of the tympanic membrane, the EAC epithelium was not healthy for long-term follow-up. The incidence of complications related to EAC reconstruction was lower than previous studies (χ²=5.55, P=0.018), and the average postoperative Air-Bone Gap increased (18.8±10.0)dB. Conclusion: By optimizing the EAC reconstruction technology, the health of the reconstructed EAC is improved compared with the previous study. After active intervention and treatment, there should be no scarring stenosis or local bone hyperplasia on the contralateral side EAC.

ABSTRACT

Objective: To explore the independent risk factors of lymph node metastasis (LNM) in early gastric cancer, and to use nomogram to construct a prediction model for above LNM. Methods: A retrospective cohort study was conducted. Inclusion criteria: (1) primary early gastric cancer as stage pT1 confirmed by postoperative pathology; (2) complete clinicopathological data. Exclusion criteria: (1) patients with advanced gastric cancer, stump gastric cancer or history of gastrectomy; (2) early gastric cancer patients confirmed by pathology after neoadjuvant chemotherapy; (3) other types of gastric tumors, such as lymphoma, neuroendocrine tumor, stromal tumor, etc.; (4) primary tumors of other organs with gastric metastasis. According to the above criteria, 1633 patients with early gastric cancer who underwent radical gastrectomy at the Department of General Surgery of the Chinese PLA General Hospital First Medical Center from December 2005 to December 2020 were enrolled as training set, meanwhile 239 patients with early gastric cancer who underwent gastrectomy at the Department of General Surgery of the Chinese PLA General Hospital Fourth Medical Center from December 2015 to December 2020 were enrolled as external validation set. Risk factors of LNM in early gastric cancer were identified by using univariate and multivariate logistic regression analyses. A nomogram prediction model was established with significant factors screened by multivariate analysis. Area under the receiver operating characteristic curve (AUC) was used for assessing the predictive value of the model. Calibration curve was drawn for external validation. Results: Among 1633 patients in training set, the mean number of retrieved lymph nodes was 20 (13-28), and 209 patients (12.8%) had lymph node metastasis. Univariate analysis showed that gender, resection range, tumor location, tumor morphology, lymph node clearance, vascular invasion, lymphatic cancer thrombus, tumor length, tumor differentiation, microscopic presence of signet ring cells and depth of tumor invasion were associated with LNM (all P<0.05). Multivariate analysis revealed that females, tumor morphology as ulcer type, vascular invasion, lymphatic cancer thrombus, tumor length≥3 cm, deeper invasion of mucosa, and poor differentiation were independent risk factors for LNM in early gastric cancers (all P<0.05). Receiver operating characteristic curve indicated that AUC of training set was 0.818 (95%CI: 0.790-0.847) and AUC of external validation set was 0.765 (95%CI: 0.688-0.843). The calibration curve showed that the LNM probability predicted by nomogram was consistent with the actual situation (C-index: 0.818 in training set and 0.765 in external validation set). Conclusions: Females, tumor morphology as ulcer type, vascular invasion, lymphatic cancer thrombus, tumor length≥3 cm, deeper invasion of mucosa and poor differentiation are independent risk factors for LNM of early gastric cancer. The establishment of a nomogram prediction model for LNM in early gastric cancer has great diagnostic value and can provide reference for treatment selection.

ABSTRACT

OBJECTIVE@#This study was done to determine the effects of different courses of moxibustion on a rat knee osteoarthritis (KOA) model, and explore the dose-effect relationship of moxibustion on KOA from the perspectives of intestinal flora and inflammatory factors.@*METHODS@#Wistar rats were randomly divided into five groups: normal, model, moxibustion for 2 weeks, moxibustion for 4 weeks and moxibustion for 6 weeks groups (n = 5 each group). A KOA rat model was induced by monosodium iodoacetate, and moxibustion intervention was performed at the acupoints "Dubi" (ST35) and "Zusanli" (ST36), once every other day. Pathologic changes in the cartilage of rat knee joints were assessed after intervention, and fecal samples were subjected to 16S rRNA high-throughput sequencing for microbial diversity analysis.@*RESULTS@#Damage to the knee articular cartilage was obvious in the model group, which also had increased levels of pro-inflammatory factors, decreased levels of anti-inflammatory factors, and intestinal flora disorders with decreased diversity. The degree of cartilage damage in the 4 and 6 weeks of moxibustion groups was significantly improved compared with the model group. The 4 and 6 weeks of moxibustion groups also demonstrated reduced levels of interleukin-1β and tumor necrosis factor-α and increased levels of interleukin-10 (P < 0.05). Both the abundance and diversity of the intestinal flora were increased, approaching those of the normal group. Abundances of probiotics Eubacterium coprostanoligenes group and Ruminococcaceae UCG-014 increased, while that of the pathogenic bacteria Lachnospiraceae NK4A136 group decreased (P < 0.05). Although the abundance of Lachnospiraceae NK4A136 group decreased in the 2 weeks of moxibustion group compared with the model group (P < 0.05), there was no statistically significant difference in serum inflammatory factors, flora species diversity or degree of pathological damage compared with the model group.@*CONCLUSION@#Moxibustion treatment led to significant improvements in the intestinal flora and inflammatory factors of rats with KOA. Moxibustion treatment of 4 and 6 weeks led to better outcomes than the 2-week course. Moxibustion for 4 and 6 weeks can regulate intestinal flora dysfunction with increased probiotics and reduced pathogenic bacteria, reduce pro-inflammatory factors and increase anti-inflammatory factors. No significant differences were seen between the effects of moxibustion for 4 weeks and 6 weeks.

ABSTRACT

Thyroid-associated ophthalmopathy(TAO)is an organ-specific autoimmune disease, which will cause a series of symptoms to significantly reduce the health level and life quality of patients. The pathogenesis of TAO has not been fully clarified. At present, there is a lack of unified and mature treatment scheme of it. Indeed, T-helper 17 lymphocyte(Th17)cells, regulatory T(Treg)cells and their imbalance are closely related to the immunological pathogenesis of TAO. It is currently believed that the cytokines secreted by Th17 cells can not only promote the inflammatory response of TAO and the fibrosis of orbital connective tissue, but also inhibit the adipogenic differentiation of TAO orbital connective tissue. In addition, Treg cells mainly exert immunosuppressive effect on TAO and delay the disease progression. At the same time, there is a dynamic balance relationship between Th17 and Treg cells, the imbalance of Th17/Treg cells can trigger the occurrence and development of TAO. This paper mainly expounds the influence mechanism of Th17, Treg cells and their balance on TAO, and analyzes the reasons for the differences between different research results, so as to provide some reference for the study of the pathogenesis and clinical treatment of TAO.
