ABSTRACT
Objective To explore a precise method with a microwave antenna for puncture of pulmonary nodules and analyze phenomena that affect the puncture results. Methods Clinical data of 107 cases with solitary malignant pulmonary nodules were collected, and the mean length of pulmonary nodules was 13.6±0.6 mm in CT axial position. A thread-hanging method was used to assist the puncture of pulmonary nodules. The procedure was successful when the needle was not withdrawn and inserted into the central region of the nodule. The success rate and complications of the pulmonary procedure were recorded. The incidence of the following phenomena were also documented: needle coercing, needle slipping, needle tip pushing, pulmonary nodule prolapsing, radial nodule deformation, nodular masking, and radial movement distance of needle tip. Results In all of 107 cases evaluated, the antenna puncture was successful in 101 cases (94.4%) but failed in 6 cases (5.6%). Pneumothorax and pulmonary hemorrhage occurred in 23 (21.5%) and 19 cases (17.8%), respectively. The following phenomena occurred: needle coercing in 9 cases (8.4%), needle slipping in 6 cases (5.6%), needle tip pushing in 19 cases (17.8%), pulmonary nodule prolapsing in 15 cases (14%), radial nodule deformation in 14 cases (13.1%), and nodular masking in 5 cases (4.7%). The mean radial adjusting distance of needle tip was 0.7±0.4 cm. Conclusion The thread-hanging method can assist in the accurate puncture of microwave antenna for pulmonary nodules. We should focus and deal with phenomena that may occur and affect the result of puncture.
ABSTRACT
Objective:To explore the characteristics of intestinal microbiota in patients with systemic lupus erythematosus (SLE), and further explore the relationship between microbiota and CD4 +T lymphocyte subsets and disease activity. Methods:Fecal samples were collected from 96 patients with SLE, and 96 sex- and age-matched healthy controls (HCs). The gut microbiota were investigated via 16s rRNA sequencing. Flow cytometry was used to detect peripheral CD4 +T lymphocyte subsets of Th1, Th2, Th17 and Treg cells. Indicators of disease activity such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), complement C3 and C4, Systemic lupus erythematosus disease activity index(SLEDAI) for each patient were recorded. Differential abundance analysis was carried out using the edgeR algorithm. The Wilcoxon rank-sum test was used to compare alpha diversity indices, bacterial abundances, and the F/B ratio between groups. R (version 4.0.1) was used for comparative statistics, and Pearson′s correlation analysis was used to assess the correlations between the relative abundances of bacterial genera and serum levels of ESR, CRP, C3 and C4 in the samples. Results:The alpha estimators of richness (ACE and Chao 1) were significantly reduced in SLE feces samples compared with those of HCs ( P<0.01). Bacterial diversity estimators, including the Shannon ( P<0.01) and Simpson′s ( P<0.01) indices, were also significantly lower in SLE. Significant differences in gut microbiota composition between SLE and HCs were found using the edgeR algorithm. Compared with HC, 24 species of bacteria were significantly different in SLE patients at the genus level ( P<0.05). Moreover, there was a significant positive correlation between CRP and Coprococcus ( r=0.30, P=0.014), C4 and Corynebacterium ( r=0.31, P=0.013) and Faecalibacterium( r=0.25, P=0.048), Hemoglobin and Morganella( r=0.41, P=0.001), as well as SLIDA and Corynebacterium( r=0.25, P=0.047). In terms of lymphocyte subsets, there was significant positive correlation between B cells, Treg cells and Eubacterium eligens group, as well as CD8 +T, CD4 +T, NK cells and Corynebacterium. In additional, Th1 was positively correlated with Shigella Escherichia coli ( r=0.52, P=0.008), and Th2 was positively correlated with Dielma ( r=0.51, P<0.001). Conclusion:The abundance and diversity of intestinal flora in SLE patients were significantly reduced, and the differentially expressed bacteria were closely related to the CD4 +T lymphocyte subsets and disease activity indicators of patients.
ABSTRACT
As a natural product with a long history of medicinal use, parthenolide has aroused great interest of chemists and biologists. Existing studies have shown that it has anti-inflammatory, antitumor and other pharmacological activities, and also revealed its action on NF-κB signaling pathway, DNMT1 enzyme and Wnt/β-catenin signaling pathway. But its biological targets remain to be elucidated systematically. Proteolysis Targeting Chimeras (PROTAC) provides a new strategy for target discovery of natural products, which can be used to explore the panorama of protein changes in cells through proteomic investigation, so as to analyze their potential targets. Based on this idea, current study designed and synthesized 20 parthenolide-derived degraders. After measured their antitumor activity in vitro, selected compounds were carried out the proteomic experiment. Finally, 139 down-regulated differentially expressed proteins were identified and the discovery of parthenolide interacting protein was preliminarily explored.
ABSTRACT
OBJECTIVE@#To observe the effect of electroacupuncture (EA) on liver protein kinase B (Akt)/forkhead box transcription factor 1 (FoxO1) signaling pathway in Zucker diabetic fatty (ZDF) rats, and to explore the possible mechanism of EA on improving liver insulin resistance of type 2 diabetes mellitus.@*METHODS@#Twelve male 2-month-old ZDF rats were fed with high-fat diet for 4 weeks to establish diabetes model. After modeling, the rats were randomly divided into a model group and an EA group, with 6 rats in each group. In addition, six male Zucker lean (ZL) rats were used as the blank group. The rats in the EA group were treated with EA at bilateral "Zusanli" (ST 36), "Sanyinjiao" (SP 6), "Weiwanxiashu" (EX-B 3), and "Pishu" (BL 20). The ipsilateral "Zusanli" (ST 36) and "Weiwanxiashu" (EX-B 3) were connected to EA device, continuous wave, frequency of 15 Hz, 20 min each time, once a day, six times a week, for a total of 4 weeks. The fasting blood glucose (FBG) in each group was compared before modeling, before intervention and after intervention; the serum levels of insulin (INS) and C-peptide were measured by radioimmunoassay method, and the insulin resistance index (HOMA-IR) was calculated; HE staining method was used to observe the liver tissue morphology; Western blot method was used to detect the protein expression of Akt, FoxO1 and phosphoenolpyruvate carboxykinase (PEPCK) in the liver.@*RESULTS@#Before intervention, compared with the blank group, FBG was increased in the model group and the EA group (P<0.01); after intervention, compared with the model group, FBG in the EA group was decreased (P<0.01). Compared with the blank group, the serum levels of INS and C-peptide, HOMA-IR, and the protein expression of hepatic FoxO1 and PEPCK were increased (P<0.01), while the protein expression of hepatic Akt was decreased (P<0.01) in the model group. Compared with the model group, the serum levels of INS and C-peptide, HOMA-IR, and the protein expression of hepatic FoxO1 and PEPCK were decreased (P<0.01), while the protein expression of hepatic Akt was increased (P<0.01) in the EA group. In the model group, the hepatocytes were structurally disordered and randomly arranged, with a large number of lipid vacuoles in the cytoplasm. In the EA group, the morphology of hepatocytes tended to be normal and lipid vacuoles were decreased.@*CONCLUSION@#EA could reduce FBG and HOMA-IR in ZDF rats, improve liver insulin resistance, which may be related to regulating Akt/FoxO1 signaling pathway.

Objective:By detecting the species and distribution of fecal flora in patients with pSS, we investigated the relationship between the alterations of the gut microbiome and its metabolic characteristics with peripheral lymphocyte subsets, and their potential role in the occurrence and development of pSS.Methods:A total of 101 pSS patients who were hospitalized in the department of rheumatology of the Second Hospital of Shanxi Medical University, and 101 age and sex-matched healthy control (HC) in the health check-up center of Shanxi Provincial People′s Hospital from January 2019 to January 2020 were enrolled for 16s rDNA-Amplicon sequencing. The statistical analysis was performed in R software 4.0.3. The Alpha diversity were compared by Wilcoxon test, and Beta diversity were compared by ANOSIM analysis between pSS patients and HC. The difference flora was analyzed by t test. The levels of peripheral lymphocyte subsets pSS patients were detected by flow cytometry. Then the relationship between characteristic flora and clinical indicators such as lymphocyte subsets, erythrocyte sedimentation rate, C-reactive protein, unstimulated whole saliva and stimulated whole saliva were analyzed using Pearson′s correlation analysis. Results:Patients with pSS exhibited a significant reduction in the richness (Chao1, ACE) and diversity (Shannon,Simpson) of gut microbiota compared with those of HC, and there was statistical significant difference in gut microbiota composition (ANOSIM, r=0.09, P=0.001). At the phylum level, the relative abundance of Firmicutes decreased and the relative abundance of Proteobacteria increased in pSS patients. At the genus level, the proportion of Escherichia-shigella ( P<0.001), Lactobacillus ( P<0.001), Bifidobacterium ( P<0.001), Subdoligranulum ( P<0.001), Alistipes ( P<0.001) and [ Eubacterium]_ coprostanoligenes (P=0.002) were increased. The proportion of Faecalibacterium ( P<0.001), Prevotella ( P<0.001), Roseburia ( P<0.001), Megamonas ( P<0.001), Agathobacter ( P<0.001), Lachnospira ( P<0.001), Lachnospira_NK4A136 ( P=0.006), [ Eubacterium] _eligens ( P<0.001) were significantly reduced. PICRUST analysis showed significant enrichment of amino acid metabolism taurine and hypotaurine metabolism ( P<0.001), fatty acid metabolism such as propanoate metabolism ( P<0.001), glutathione metabolism ( P=0.002), lipoic acid metabolism ( P=0.003), lipopolysaccharide biosynthesis and biosynthesis of siderophore group nonribosomal peptides ( P=0.005) and Aminobenzoate degradation ( P=0.002) in patients with pSS. The Pearson correlation results showed that there were significant different in the abundances of the key gut microbiota between the HC and pSS groups, and they were closely related to unstimulated whole saliva, the absolute number of Treg cells and Th17 cells. Conclusion:The dysbiosis and metabolism changes of the pSS intestinal microbiota may contribute to immune homeostasis imbalance, and may be involved in the occurrence and development of pSS.

Conclusion:The health behavior level of stroke patients need to be improved. The relevant community resource allocation system continuously, and focus on the impact of family environment and particularly the elderly and patients with a history of hypertension should be attentioned when improving the health behavior of patients.
ABSTRACT
Objective: The objective of this paper was to investigate hub genes of postmenopausal osteoporosis (PO) utilizing benchmarked dataset and gene regulatory network (GRN). Materials and Methods: To achieve this goal, the first step was to benchmark the dataset downloaded from the ArrayExpress database by adding local noise and global noise. Second, differentially expressed genes (DEGs) between PO and normal controls were identified using the Linear Models for Microarray Data package based on benchmarked dataset. Third, five kinds of GRN inference methods, which comprised Zscore, GeneNet, context likelihood of relatedness (CLR) algorithm, Partial Correlation coefficient with Information Theory (PCIT), and GEne Network Inference with Ensemble of trees (Genie3), were described and evaluated by receiver operating characteristic (ROC) and precision and recall (PR) curves. Finally, GRN constructed according to the method with best performance was implemented to conduct topological centrality (closeness) for the purpose of investigate hub genes of PO. Results:A total of 236 DEGs were obtained based on benchmarked dataset of 20,554 genes. By assessing Zscore, GeneNet, CLR, PCIT, and Genie3 on the basis of ROC and PR curves, Genie3 had a clear advantage than others and was applied to construct the GRN which was composed of 236 nodes and 27,730 edges. Closeness centrality analysis of GRN was carried out, and we identified 14 hub genes (such as TTN, ACTA1, and MYBPC1) for PO. Conclusion: In conclusion, we have identified 14 hub genes (such as TN, ACTA1, and MYBPC1) based on benchmarked dataset and GRN. These genes might be potential biomarkers and give insights for diagnose and treatment of PO
ABSTRACT
Objective::To study the anti-depressive effect of Qing' ewan in treating chronic unpredictable mild stress (CUMS) in rats, and the regulatory effect on estrogen receptor and estrogen receptor-related signaling pathways, in order to explore its anti-depressive mechanism. Method::The CUMS model was established. The experiment was divided into normal control group, model group, escitalopram oxalate group (positive control) and Qing' ewan groups (1.71, 5.13, 15.39 g·kg-1). After 4 weeks of modeling, rats were treated with corresponding drugs for 2 weeks. Behavioral evaluation [sucrose preference test (SPT), forced swimming test (FST), open field test (OFT)] was conducted to assess if the CUMS model was successful. Western blot was used to analyze the protein expression levels of estrogen receptor α (ERα), estrogen receptor β (ERβ), brain-derived neurotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB). Result::Compared with the normal group, the sucrose consumption rate and the score of OFT in the model group decreased(P<0.05, P<0.01), the immobility time of FST prolonged significantly(P<0.01), and the protein expression levels of ERα, ERβ, BDNF and TrkB decreased(P<0.05, P<0.01). Compared with the model group, the behavioral performance of the treated group was improved, the sucrose consumption rate and the score of OFT increased(P<0.05, P<0.01), and the immobility time decreased(P<0.05). The protein expressions of ERα, ERβ, BDNF and TrkB in the treated group were significantly up-regulated(P<0.05, P<0.01), especially the middle-dose Qing' ewan group (5.13 g·kg-1). Conclusion::Qing' ewan can improve depression-like behavior in CUMS rats. Its mechanism may be related to the neuroprotective effect by up-regulating the expressions of ERα and ERβ and activating estrogen receptor-mediated ERβ/BDNF/TrkB pathways.
ABSTRACT
OBJECTIVE@#This study aimed to compare the passive fits of implant-supported cement-retained computer aided design/computer aided manufacturing (CAD/CAM) bridges fabricated with different implant superstructure designs from zirconia and titanium.@*METHODS@#A total of 32 cubic clods with the same dimensions and with elastic modulus similar to that of mandibles were used. Each clod received two one-stage implants to simulate a partially edentulous jaw that was missing teeth between the lower left second premolar and second molar. Four linear strain gauges were bonded on the region surrounding each implant on the mesial, buccal, distal, and lingual aspects. A total of 32 identical frameworks were fabricated through CAD/CAM after scanning. The frameworks were allocated into four different groups (n=8) in accordance with material types and superstructure designs. Group A included zirconia ceramic implant-supported fixed prostheses with regular marginal designs. Group B comprised zirconia ceramic implant-supported fixed prostheses with full circumferential zirconia-collar marginal designs. Group C consisted of titanium ceramic implant-supported fixed prostheses with regular marginal designs. Group D included titanium ceramic implant-supported fixed prostheses with full circumferential titanium-collar marginal designs. Strain development before and after ceramic veneering was recorded during cement setting. Data were statistically analyzed by using SPSS software.@*RESULTS@#Before ceramic veneering, material types affected the strains of prostheses, and zirconia frameworks showed lower strain than other frameworks (P0.05). Nevertheless, the full circumferential collar marginal design reduced discrepancies among groups (P<0.01).@*CONCLUSIONS@#The passive fits of zirconia prostheses were better than those of titanium-based porcelain-fused-to-metal restorations. The full circumferential collar marginal design can help reduce fit inaccuracy, as well as the adverse effects of ceramic veneering.

ABSTRACT
Objective RegIV, which is the latest member of the regenerative gene family, has been found to be closely related to the development of various tumors, but rarely reported in invasive breast cancer. This article is intended to explore the expression levels of regenerative factor 4(regeneration islet-derived family, member 4, RegIV), and the correlation with clinicopathological features and prognosis in 4 molecular subtypes of breast cancer(LA, LB,HER-2+, TNBC). Methods Pathological data of 284 breast cancer patients from March 2011 to October 2017 in the department of pathology, Lianyungang first people’s hospital were collected. To analyze the expression of RegIV in different molecular subtypes (LA, LB, HER-2+, TNBC) and its relationship with clinicopathological features, we analyzed the expression level of RegIVmRNA in breast cancer and its prognosis of patients. Results The positive rates of Reg IV in Luminal A group, Luminal B group, HER-2 positive group and triple negative breast cancer were 52.11%(37/71), 50.00%(42/84), 65.22%(45/69)and 20.00%(12/60),which was statistically significant when comparing them in pairs(P<0.01). The expression of RegIV was associated with tumor diameter, lymph node metastasis, TNM stage(P<0.01). The recurrence risk of breast cancer patients with high RegIV expression was lower than those with low RegIV expression (HR=0.59,95%CI:0.50-0.69). Further analysis found that the recurrence risk of LA breast cancer patients with high RegIV expression (HR=0.63,95%CI:0.48-0.82), and so it was with LB(HR=0.56,95%CI:0.40-0.76) and TNBC(HR=0.51,95%CI:0.36-0.71). Conclusion RegIV can provide reference for molecular subtypes diagnosis and it may be one of the indicators to evaluate the prognosis of breast cancer patients.

<p><b>OBJECTIVE</b>To retrospectively analyze the clinical data of 17 patients with bone cement leakage after percutaneous kyphoplasty and explore the leakage type and mid-term clinical effects.</p><p><b>METHODS</b>The clinical data of 17 patients with osteoporotic vertebral compression fractures occurred bone cement leakage after percutaneous kyphoplasty from October 2011 to October 2016 were collected. There were 7 males and 10 females, aged from 68 to 87 years old with an average of 78 years. All the patients had the history of low emergy trauma who had normal activity and full self-care for living before trauma, and complained with the lower back pain without signs and symptoms of nerve root injury after trauma. According to the anatomical location by images, the bone cement leakage pathways was confirmed, the preoperative and postoperative vertebral body height and Cobb angle were measured, the improvement of spinal stenosis were recorded. Preoperative and postoperative visual analogue scale (VAS) and Oswestry Disability Index(ODI) were used to evaluate pain and daily activities.</p><p><b>RESULTS</b>All the patients were followed up for 4 to 7 years with an average of 5.1 years. According to anatomical location by images, we found the bone cement leakage pathways of vertebral side type in 6 cases, intervertebral disc type in 3 cases, spinal canal type in 2 cases, vertebral pedicle type in 5 cases and mixed type in 1 case. Vertebral body height from preoperative(27.7±3.5)% restored to (56.4±2.5)% at final follow-up, and the kyphosis was corrected with Cobb angle from preoperative(45.3±4.2)° corrected to(18.3±3.1)° at final follow-up. VAS score decreased from preoperative 7.9±1.5 to 2.1±0.5 at final follow-up. ODI obviously restored from preoperative(49.1±7.5)% to (23.5±3.7)% at final follow-up. The nerve symptoms in lower limbs occurred in 2 cases, and the neurological symptom was disappeared after urgent symptomatic treatment and anaphase trophic nerve treating. Lower back pain occurred in 3 cases, including one case of unbearable pain, and the pain disappeared after symptomatic treatment.</p><p><b>CONCLUSIONS</b>Although the rate of bone cement leakage during percutaneous vertebral kyphoplasty is not low, the bone cement leakage has little influence on PKP surgery. Even if a little leakage occurred within the spinal canal during the surgery, spinal canal decompression will not be needed urgently. The significant clinical symptoms caused by leakage can basically disappear after treatment in mid-term follow-up.</p>
ABSTRACT
The study is aimed at determine the content of anthocyanins and expressions of relative genes and activity of relative enzymes. The effects of flood stress on anthocyanins synthesis with relative genes and enzymes of Chrysanthemum morifolium cv. 'Hangju' were analyzed. The expression of CHS and the content of CHS presented the trend of first rising and after downward with the increase of flowering degree. The content of anthocyanins, the expression of DFR and the activity of DFR presented the trend of first downward and after rising with the increase of flowering degree. There was a positive correlation among anthocyanins,DFR gene and DFR. However there was no significant correlation among anthocyanins,CHS gene and CHS. Flood stress has significant effects on anthocyanins synthesis with relative genes and enzymes of Ch. morifolium cv. 'Hangju',but don't change the patterns of genes expression and anthocyanins and enzymes accumulation. DFR and DFR are the key gene and key enzyme of anthocyanins synthesis.
ABSTRACT
[Objective]Screening mutation sites of POGZ gene in 100 intellectual disability patients to explore their pathogenesis relationship.[Method]Genomic DNA was isolated from peripheral blood. All exons,exon-intron boundaries,5'UTR and 3'UTR of POGZ were amplified by PCR and PCR products were directly sequenced.[Results]A novel mutation was identified,and the mis?sense mutation disrupted the unique zing-finger like motif of POGZ,which is a critical element for binding Hp1. The mutated POGZ failed to bind with HP1 thus might lose its cell cycle regulation function.[Conclusion]Mutations of POGZ gene weighs more in intel?lectual disability etiology. Screening of POGZ in unexplained intellectual disability patients contributes to their pathogenesis analyze , screening of POGZ in pregnants with family history of intellectual disability can prevent intellectual disability from birthing.
ABSTRACT
Objective To explore the clinical effect of coracoclavicular ligament reconstruction with the autogenous anterior half of peroneus longus tendon (AHPLT) for distal clavicle fracture (Neer type Ⅱ-b).Methods The clinical data were retrospectively analyzed of 26 Neer type Ⅱ-b distal clavicle fracture surgically treated by coracoclavicular ligament reconstruction with autogenous AHPLT in Ganyu District People's Hospital of Lianyungang from June 2012 to May 2015.Among the 26 cases,16 males and 10 females,aged from 19-56 years (average 38.7 years).Fracture occurred in left side in 18 cases and in right side in 8 cases.Postoperative observations were done on fracture healing,shoulder and ankle-foot function recovery.Results For all the 26 cases,surgical incisions were healed well,and no infection,vascular and peroneal nerve injury and iatrogenic fracture occurred.Follow-up was carried out for 10-24 months with average of 15.3 months.All the fractures were healed within 12-20 weeks with an average of 14.6 weeks.One patient was found of losing the fracture reduction part during the follow-up process,and then got eventual healing by extending the limb brake time.Another patient was found of slight tendon sensation disorder with no significant effect on daily life and exercise,and the symptoms disappeared 6 months later.At the last follow-up,the Constant-Murley score was 92-100 with an average of 97.8 points.The ankle-hind foot score of American Society of Ankle and Orthopedics was excellent.Conclusion Reconstruction of coracoclavicular ligament with autogenous AHPLT is an effective treatment for Neer type Ⅱ-b distal clavicle fracture with good safety and without negative effect on the ankle-foot function,and thus it is worthy of wider clinical use.
ABSTRACT
Objective: To explore the effect of different amounts of branches on medicinal quality of T. chinense. Methods: Wild T. chinense taken from Jurong, Guli, and Maoshan was used as experimental materials. T. Chinense was divided into five levels according to the number of branches. The first level has 1-3 branches, 4-6 branches as second. The third level has 7-9 branches, 10-20 branches as fourth, and the fifth level has 20 or more branches. Quality of T. chinense was measured by growth indicators and effective components. Results: The quality of T. chinense in different levels was significantly different. The difference of dry weight of T. chinense could be up to 25 times, fifth level was 5.710 6 g, but the first level was only 0.224 5 g. The content of effective components and branch number were negatively correlated, flavonoids and kaempferol contents of T. chinense in level 1 were significantly higher than those in other levels which were 4.02% and 3.38 mg/g. In different branches levels of T. chinense, there was a significant positive correlation between flavonoids and kaempferol contents, but there was a significant negative correlation between kaempferol content and root crude of T. chinense. Conclusion: The number of T. chinense branches has a great impact on its quality, the more branches, the higher yield, and the lower content of active ingredient.
