RESUMO

Network Meta-analysis has been widely applied in the field of traditional Chinese medicine(TCM) due to its unique advantages. This study aimed to conduct a visual analysis on the state of the application network Meta-analysis in the field of traditional Chinese medicine. Databases of CNKI and Web of Science were retrieved to identify the qualified literatures and then screen out their titles and abstracts. Institutions, authors, cited references, and keywords were analyzed using the information visualization analysis software CiteSpace. Finally, 79 English and 186 Chinese articles were included. The results indicated that the literatures were mainly published in Chinese, and the number of articles was increased rapidly since 2015. Cooperation between institutions and authors were mainly concentrated inside the institutions. The most important four institutions were four universities who attached more importance to evidence-based medical education and academic exploration. The keywords beside the method of network Meta-analysis could be summarized into three types: the main interventions in traditional Chinese medicine(Chinese herbal injection, herb medicine, acupuncture, etc.), disease types(cancer, circulatory system disease, bone joint disease, urinary system disease, etc.) and the outcome of interests(efficacy, safety, symptom, survive, mortality, etc.), which reflected the current research hotspots to certain extent. In addition, the most cited articles were methodology articles, including the introduction of methodology and the guides of application software, suggesting that the exploration of methodological articles will be extremely concerned.

RESUMO

BACKGROUND: The popular methods for evaluating the initial therapeutic effect (ITE) of noninvasive positive pressure ventilation (NPPV) can only roughly reflect the therapeutic outcome of a patient's ventilation because they are subjective, invasive and time-delayed. In contrast, vibration response imaging (VRI) can monitor the function of a patient's ventilation over the NPPV therapy in a non-invasive manner. This study aimed to investigate the value of VRI in evaluating the ITE of NPPV for patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). METHODS: Thirty-six AECOPD patients received VRI at three time points: before NPPV treatment (T1), at 15 min of NPPV treatment (T2), and at 15 min after the end of NPPV treatment (T4). Blood gas analysis was also performed at T1 and at 2 hours of NPPV treatment (T3). Thirty-nine healthy volunteers also received VRI at T1 and T2. VRI examination at the time point T2 in either the patients or volunteers did not require any interruption of the on-going NPPV. The clinical indices at each time point were compared between the two groups. Moreover, correlations between the PaCO2 changes (T3 vs T1) and abnormal VRI scores (AVRIS) changes (T2 vs T1) were analyzed. RESULTS: No significant AVRIS differences were found between T1 and T2 in the healthy controls (8.51 ± 3.36 vs. 8.53 ± 3.57, P > 0.05). The AVRIS, dynamic score, MEF score and EVP score showed a significant decrease in AECOPD patients at T2 compared with T1 (P < 0.05), but a significant increase at T4 compared with T2 (P < 0.05). We also found a positive correlation (R2 = 0.6399) between the PaCO2 changes (T3 vs T1) and AVRIS changes (T2 vs T1). CONCLUSIONS: VRI is a promising noninvasive tool for evaluating the initial therapeutic effects of NPPV in AECOPD patients and predicting the success of NPPV in the early stage.

RESUMO

Background: Hepatoblastoma is a common hepatic tumor occurring in children between 0-5 years. Accumulating studies have shown lncRNA's potential role in distinct cancer progression and development, including hepatoblastoma. SnoRNA host gene 9 (SNHG9) is associated with the progression of distinct human cancers, but, its specific molecular mechanisms in hepatoblastoma is not unknown. Methods: In this study, we estimated SNHG9 expression in hepatoblastoma tissue and cell lines by quantitative Real-Time Polymerase Chain Reaction (qRT-PCR). Next, we downregulated and upregulated SNHG9 expression in hepatoblastoma cell lines and then determined cell proliferation (CCK-8), colony formation, and cellular apoptosis activity. The dual luciferase reporter activity, RNA immunoprecipitation (RIP), biotin RNA pull down and Spemann's Pearson correlation coefficient assay were performed to establish the interaction between SNHG9, WNt3a and miR- 23a-5p. A xenograft in-vivo tumorgenicity test was performed to elucidate the role of SNHG9 hepatoblastoma in tumorigenesis. SNHG9 role in Cisplatin drug resistance in hepatoblastoma was also determined. Results: SNHG9 was significantly upregulated in hepatoblastoma tissue and cell lines. SNHG9 overexpression on HUH6 & HepG2 resulted in a significant increase in cell proliferation and clonogenic activity while SNHG9 knock down resulted in a sustained inhibition of cell proliferation and clonogenic activity. Dual luciferase activity, RNA immunoprecipitation and biotin pull down confirmed the direct interaction of miR-23a-5p with SNHG9. The xenograft tumorgenicity test showed SNHG9 downregulation significantly inhibited the tumor growth in BALB/c mice. ROC and Kaplan-Meier analysis showed potential prognostic and diagnostic importance of SNHG9 in hepatoblastoma. Conclusion: We concluded that SNHG9/miR-23a-5p/Wnt3a axis promotes the progression hepatoblastoma tumor.

RESUMO

Protein disulfide isomerase (PDI), a principal endoplasmic reticulum resident oxidoreductase chaperone, is known to play a role in malignancies. This study aims to explore the molecular mechanism by which PDI regulates endoplasmic reticulum stress and the apoptosis signaling pathway in colorectal cancer (CRC). We determined the expression of PDI in CRC tissues and adjacent normal tissues. Gain- and loss- of function assays were conducted to evaluate the effects of PDI on oxidative stress, endoplasmic reticulum stress, and apoptosis in CRC cells, as reflected by hydrogen peroxide (H2O2) level and the expression of related proteins. PDI protein expression was upregulated in CRC tissues. Small molecule inhibitor of PDI or PDI knockdown reduced CRC cell viability and induced apoptosis. Overexpression of wild-type PDI augmented the viability of CRC cells and inhibited endoplasmic reticulum stress response and apoptosis. Small molecule inhibitor of PDI or PDI knockdown increased intracellular H2O2 level and activated apoptosis signaling pathway, which could be reversed by wild-type PDI restoration. Moreover, the catalytic active site of C-terminal of PDI was found to be indispensable for the regulatory effects of PDI on H2O2 levels, apoptosis and cell viability in CRC cells. Collectively, PDI inhibits endoplasmic reticulum stress and apoptosis of CRC cells through its oxidoreductase activity, thereby promoting the malignancy of CRC.

RESUMO

In the title three-dimensional heterometallic complex, {[AgHo(C(6)H(4)NO(2))(2)(C(2)H(3)O(2))(H(2)O)]ClO(4)}(n), the Ho(III) ion is eight-coordinated by four O atoms from four different isonicotinate ligands, three O atoms from two different acetate ligands and one O atom of a water mol-ecule. The two-coordinate Ag(I) ion is bonded to two N atoms from two different isonicotinate anions. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network. The coordinated water mol-ecules link the carboxyl-ate group of the acetate ligand and the nitrate ligand by O-H⋯O hydrogen bonding. The crystal structure is further stabilized by hydrogen bonds. The perchlorate ion is disordered over two sites with site-occupancy factors 0.539 (12) and 0.461 (12), while the methyl group of the acetate ligand is disordered over two sites with site-occupancy factors 0.51 (4) and 0.49 (4).

RESUMO

Foot-and-mouth disease virus (FMDV) is an important pathogen that affects livestock breeding and causes huge economic losses worldwide. Currently, the development of antiviral agents to combat FMDV infection at the early stages is being explored. As viral replication critically depends on the host for nucleoside supply, host enzymes involved in nucleotides biosynthesis may represent potential targets for the development of antiviral agents. In the present study, the effects of IMP dehydrogenase (AVN-944 and mycophenolate mofetil) and dihydroorotate dehydrogenase (teriflunomide) inhibitors were evaluated both in vitro and in vivo. The results revealed that these compounds were effective in suppressing FMDV (O/MY98/BY/2010 and A/GD/MM/2013) infection. With regard to the antiviral mechanism, time-of-addition experiments revealed that these compounds were effective when added at the early stages of viral lifecycle (0-8 h post infection). However, exogenous guanosine/uridine eliminated the antiviral activity of these compounds. Importantly, treatment AVN-944 and teriflunomide significantly improved the survival of mice that were subcutaneously treated with FMDV. Together, the results of the present study indicate the broad-spectrum activities of anti-FMDV agents targeting IMP dehydrogenase or dihydroorotate dehydrogenase, which could be useful in developing strategies to prevent FMD.

RESUMO

The title samarium coordination polymer, [Sm(3)(C(8)H(7)O(2))(9)](n), was obtained by the hydro-thermal reaction of Sm(NO(3))(3) with 4-methyl-benzoic acid in alkaline aqueous solution. In the asymmetric unit, there are three crystallographically independent Sm(III) ions, two of which are eight-coordinate in a distorted square-anti-prismatic environment, while the third is nine-coordinate in a distorted tricapped trigonal-prismatic coordination. The metal centres are coordinated and bridged by four tridentate, three bidentate and two monodentate methyl-benzoate anions, forming polymeric chains running parallel to the b axis.

RESUMO

In the title binuclear complex, [Fe(2)(C(8)H(7)O(2))(4)(C(12)H(8)N(2))(2)(H(2)O)], the Fe(II) ion is six-coordinated by three carboxylate O atoms from three 4-methyl-benzoate ligands, two N atoms from two 1,10-phenanthroline ligands and one bridging aqua ligand in a distorted octa-hedral geometry. The coordinated water mol-ecule acting as the bridging ligand is located on a twofold axes and the complex mol-ecule displays C(2) mol-ecular symmetry. The Fe⋯Fe separation in the binuclear complex is 3.490 (3) Å. The crystal structure is stabilized by hydrogen bonding and π-π stacking inter-actions [the centroid-centroid distance between adjacent 1,10-phenanthroline ring systems is 3.653 (2) Å, and that between the 1,10-phenanthroline ring system and the phenyl ring of the 4-methyl-benzoate unit of a neighbouring complex is 3.622 (3) Å].

RESUMO

The title compound, C(13)H(10)O(3), has potential oxygen donor and acceptor sites. Inter-molecular hydrogen bonding between neighboring carboxyl-ate groups leads to the formation of hydrogen-bonded dimers [graph-set motif R(2) (2)(8)]. A second hydrogen-bonding inter-action between the hydr-oxy groups generates a chain and extends the structure into a lamellar layer. One of the benzene rings is disordered over two positions with an occupancy ratio of 0.57 (2):0.43 (2).

RESUMO

AIM: To compare the efficacy of aflibercept and ranibizumab in the treatment of diabetic macular edema(DME).METHODS: Prospective randomized controlled trial. A total of 35 patients(60 eyes)with non-proliferative diabetic retinopathy complicated with DME confirmed in our hospital from June 2020 to September 2021 were included. Intravitreal injection was performed using the 3+PRN protocol in all cases, of which 17 cases(30 eyes)received aflibercept treatment(aflibercept group)and 18 cases(30 eyes)received ranibizumab(ranibizumab group). The two groups were followed up for 12mo, observing the central macular thickness(CMT)and the best corrected visual acuity(BCVA)of the two groups, and recording the number of intravitreal injections and the occurrence of complications.RESULTS: After treatment, CMT and BCVA in the aflibercept group were significantly better than that in the ranibizumab group at 1, 3, 6 and 12 mo(all P&#x003C;0.001). During the follow-up period, the number of intravitreal injections in the aflibercept group was lower than that in the ranibizumab group(4.23±0.86 vs. 6.40±0.97, P&#x003C;0.05), there were no serious complications such as drug-related adverse reactions, intraocular infection, and vascular embolism in either group.CONCLUSION: Both aflibercept and ranibizumab have clear efficacy and safety in the treatment of DME, and aflibercept may be a more effective and convenient treatment option than ranibizumab for DME patients.

RESUMO

AIM: To investigate the efficacy of pars plana vitrectomy(PPV)combined with preoperative intravitreal injection of conbercept in the treatment of proliferative diabetic retinopathy(PDR)and its effect on aqueous humor inflammatory factors.METHODS: A non-randomized controlled clinical trial was designed. The clinical data of 100 patients(100 eyes)with PDR who were admitted to the hospital from March 2019 to January 2022 were collected(the heavier eye was selected when both eyes had PDR, while the right eye was selected when the PDR degree was the same)and divided into control group and combined group according to their treatment wishes. The 48 eyes in the control group received PPV alone, and 52 eyes in the combined group received intravitreal injection of conbercept combined with PPV. Follow-up period was 12mo. The operative time, pre-and post-operative best corrected visual acuity(BCVA LogMAR), central retinal thickness(CRT)and postoperative complications in the two groups were statistically analyzed. And the levels of inflammatory factors(IL-6, IL-10, IFN-γ and TNF-α)in aqueous humor were compared between the two groups.RESULTS: Compared with the control group, the levels of inflammatory factors IL-6, IL-10, IFN-γ and TNF-α in aqueous humor in combination group were significantly decreased. The operation time of the combined group was significantly shorter than that of the control group, and the number of electrocoagulation, iatrogenic retinal hole and silicone oil filling were less in the combined group than those in the control group(all P&#x003C;0.05). There was no significant difference in preoperative BCVA and CRT between the two groups(all P&#x003E;0.05). The BCVA and CRT improved at 1, 6 and 12mo after surgery in both groups, but the improvement was more significant in the combined group(all P&#x003C;0.05). The postoperative incidence of complications in the combined group were lower than that in the control group(11.5% vs. 35.4%, P&#x003C;0.05). There was no significant difference in the recurrence rate of PDR between the two groups(P&#x003E;0.05).CONCLUSIONS: Intravitreal injection of conbercept combined with PPV in the treatment of PDR has a significant effect, which can shorten the operation time, inhibit the inflammatory effect, reduce postoperative complications, and contribute to the improvement of patients' vision.

RESUMO

The theory of membrane anatomy has been widely used in the field of colorectal surgery. The key point to perform high quality total mesorectal excision (TME) and complete mesocolic excision (CME) is to identify the correct anatomical plane. Intraoperative identification of the various fasciae and fascial spaces is the key to accessing the correct surgical plane and surgical success. The landmark vessels refer to the small vessels that originate from the original peritoneum on the surface of the abdominal viscera during embryonic development and are produced by the fusion of the fascial space. From the point of view of embryonic development, the abdominopelvic fascial structure is a continuous unit, and the landmark vessels on its surface do not change morphologically with the fusion of fasciae and have a specific pattern. Drawing on previous literature and clinical surgical observations, we believe that tiny vessels could be used to identify various fused fasciae and anatomical planes. This is a specific example of membrane anatomical surgery.

RESUMO

The aim of the present study was to investigate the association between Ki-67 expression and radiomics features of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in patients with invasive breast cancer. A total of 53 cases with low-Ki-67 expression (Ki-67 proliferation index <14%) and 106 cases with high-Ki-67 expression (Ki-67 proliferation index >14%) were investigated. A systematic approach was applied that focused on the automated segmentation of lesions and extraction of radiomics features. For each lesion 5 morphology, 4 gray-scale histogram and 6 texture features were obtained, and statistical analyzes were performed to assess the differences in these features between the low- and high-Ki-67 expressions. One morphology metric (area), 3 gray-scale histogram indexes (standard deviation, skewness and kurtosis) and 3 texture features (contrast, homogeneity and inverse differential moment) demonstrated a significant difference (P<0.05), with low-Ki-67 expression lesions tending to be smaller, clearer and heterogeneous when compared with the high-Ki-67 expressed cases. These results may provide a noninvasive means to better understand the proliferation of breast cancer.

RESUMO

This study summarizes the clinical thinking of acupuncture for snoring based on "disharmony qi leads to restlessness". According to the pathological characteristics of qi stagnation and blood stasis, phlegm dampness and internal obstruction in snoring patients, combined with the etiology, pathogenesis and location of the disease, the innovative viewpoint of "disharmony qi leads to restlessness" is proposed. It is believed that the key to snoring treatment lies in "regulating qi ". In clinical practice, acupuncture can directly regulate the qi of the disease's location, regulate the qi of the organs and viscera, and regulate the qi of the meridians to achieve overall regulation of the body's internal and external qi, smooth circulation of qi and blood, and ultimately achieve the therapeutic goal of harmonizing qi, stopping snoring, and improving sleep quality.

RESUMO

BACKGROUND@#Current guidelines recommend hepatocellular carcinoma (HCC) screening in high-risk populations. However, the ideal HCC screening interval and screening modality have not been determined. This study aimed to compare the screening efficacy among different modalities with various intervals.@*METHODS@#PubMed and other nine databases were searched through June 30, 2021. Binary outcomes were pooled using risk ratio (RR) with 95% confidence intervals (CIs). Survival rates were also pooled using RR with 95% CIs because most eligible studies only provided the number of survival patients instead of hazard ratio.@*RESULTS@#In all, 13 studies were included. Two random controlled trials (RCTs) and six cohort studies compared screening intervals for ultrasonography (US) screening and found no significant differences between shorter (3- or 4-month) and longer (6- or 12-month) screening intervals in terms of early HCC proportion, HCC significant mortality, 1-year survival rate; screening at 6-month interval significantly increased the proportion of early HCC (RR = 1.17, 95% confidence interval [CI]: 1.08-1.26) and prolonged the 5-year survival rate (RR = 1.39, 95% CI: 1.07-1.82) relative to the 12-month interval results. Three other RCTs and two cohort studies compared different screening modalities in cirrhosis or chronic hepatitis B, which indicated no statistical differences in the proportion of early HCC (RR = 0.89, 95% CI: 0.40-1.96) and HCC mortality (RR = 0.69, 95% CI: 0.23-2.09) between the biannual US and annual computed tomography (CT screening). Biannual US screening showed a lower proportion of early HCC than biannual magnetic resonance imaging (MRI) (RR = 0.60, 95% CI: 0.37-0.97) and biannual US combined with annual CT (RR = 1.31, 95% CI: 1.13-1.51) screening. The proportion of early HCC in the contrast-enhanced US group was slightly higher than that in the B-mode US (RR = 1.08, 95% CI: 1.00-1.23) group.@*CONCLUSIONS@#The evidence suggests that 6 months may be the best HCC screening interval for US screening. The effectiveness of CT and MRI is better than US during same screening intervals. However, MRI and CT are more expensive than US, and CT also can increase the risk of radiation exposure. The selection of CT or MRI instead of US should be carefully considered.@*REGISTRATION@#No. CRD42020148258 at PROSPERO website ( https://www.crd.york.ac.uk/PROSPERO/ ).
