ABSTRACT

@#The endocrown, a modified overlay or crown, is considered to have the advantages of adhesive retention and mechanical retention. Marginal adaptation and mechanical strength are common criteria for evaluating endocrowns. This review studied these aspects of endocrowns to guide further clinical application. Results from previous academic studies indicate that endocrowns made of different materials, such as glass-based ceramics, zirconia-based ceramics and resin-based ceramics, exhibit clinically acceptable marginal adaptation. Zirconia is a common dental material, but when used in endocrowns, it tends to present a risk of irreparable tooth root fractures. Compared with products manufactured with zirconia, endocrowns manufactured with resin-based ceramics and glass-based ceramics, such as lithium disilicate ceramics, do not tend to cause irreparable results, such as tooth root fracture, but their mechanical strengths are not as good as those of zirconia. At the same time, the tooth prepration design such as the types of endocrowns, the pulp chamber extension depth and angles, the endocrown thickness can influence the mechanical strength of endocrowns as well. Compared with traditional zirconia, self-glazed zirconia, a new type of material used to restore defective teeth, has the similar elasticity modulus(210 GPa)and better aesthetic advantages, and is suitable for short crown patients with insufficient occlusal space. Further study is warranted to improve the performance of endocrowns made from ceramic materials to prevent root fracture.

ABSTRACT

Chronic stress leads to many psychiatric disorders, including social and anxiety disorders that are associated with over-activation of neurons in the basolateral amygdala (BLA). However, not all individuals develop psychiatric diseases, many showing considerable resilience against stress exposure. Whether BLA neuronal activity is involved in regulating an individual's vulnerability to stress remains elusive. In this study, using a mouse model of chronic social defeat stress (CSDS), we divided the mice into susceptible and resilient subgroups based on their social interaction behavior. Using in vivo fiber photometry and in vitro patch-clamp recording, we showed that CSDS persistently (after 20 days of recovery from stress) increased BLA neuronal activity in all the mice regardless of their susceptible or resilient nature, although impaired social interaction behavior was only observed in susceptible mice. Increased anxiety-like behavior, on the other hand, was evident in both groups. Notably, the CSDS-induced increase of BLA neuronal activity correlated well with the heightened anxiety-like but not the social avoidance behavior in mice. These findings provide new insight to our understanding of the role of neuronal activity in the amygdala in mediating stress-related psychiatric disorders.

ABSTRACT

To improve the diagnostic efficiency of prostate cancer (PCa) and reduce unnecessary biopsies, we defined and analyzed the diagnostic efficiency of peripheral zone prostate-specific antigen (PSA) density (PZ-PSAD). Patients who underwent systematic 12-core prostate biopsies in Shanghai General Hospital (Shanghai, China) between January 2012 and January 2018 were retrospectively identified (n = 529). Another group of patients with benign prostatic hyperplasia (n = 100) were randomly preselected to obtain the PSA density of the non-PCa cohort (N-PSAD). Prostate volumes and transition zone volumes were measured using multiparameter magnetic resonance imaging (mpMRI) and were combined with PSA and N-PSAD to obtain the PZ-PSAD from a specific algorithm. Receiver operating characteristic (ROC) curve analysis was used to assess the PCa detection efficiency in patients stratified by PSA level, and the area under the ROC curve (AUC) of PZ-PSAD was higher than that of PSA, PSA density (PSAD), and transition zone PSA density (TZ-PSAD). PZ-PSAD could amend the diagnosis for more than half of the patients with inaccurate transrectal ultrasonography (TRUS) and mpMRI results. When TRUS and mpMRI findings were ambiguous to predict PCa (PIRADS score ≤3), PZ-PSAD could increase the positive rate of biopsy from 21.7% to 54.7%, and help 63.8% (150/235) of patients avoid unnecessary prostate biopsy. In patients whose PSA was 4.0-10.0 ng ml

ABSTRACT

Objective@#To analyze the epidemiological characteristics of coronavirus disease 2019 (COVID-19) cases reported in Ningbo from January 22 to February 22, 2020, so as to provide guidance for the prevention and control of the COVID-19 epidemic.@*Methods@#The confirmed cases of COVID-19 reported by Ningbo were selected from National Diseases Prevention and Control Information System to analyze the epidemiological characteristics by descriptive epidemiological method, including time, spatial and population distribution, clinical symptoms and exposure history.@*Results@#A total of 157 confirmed cases of COVID-19 were reported and there was no death. The first confirmed case was reported on January 22. On the incidence curve, the peak was from January 22 to February 4, with a maximum of 15 cases in a single day. The incidence curve presented sustained human-to-human transmission. The number of the cases showed a declining trend from February 5. The confirmed cases were reported in all 10 counties(cities or districts),among which 69(43.95%)cases were reported in Haishu District. The confirmed cases were mainly 30-69 years old,accounting for 78.34%;were mainly farmers,household workers and retired people,accounting for 59.87%;and were mainly clinically mild,accounting for 87.90%.There were 51 imported cases, accounting for 32.48%. The initial confirmed case was a local case. In the early stage of the epidemic, local cases and imported cases prevalent together,which was due to the outbreak caused by the large-scale buddhist activity on January 19.This event resulted in 67 confirmed cases and 15 asymptomatic cases. There totally reported 22 clusters with 138 (87.90%)confirmed cases. @*Conclusions@# In the early stage of the COVID-19 epidemic in Ningbo, the imported cases and local cases prevalent at the same time. Most of the cases were female, aged from 30 to 69 years, and their occupation were farmers, household workers and retired people. With comprehensive measures taken, the epidemic of COVID-19 in Ningbo have been under control.

ABSTRACT

Objective@#To explore the clinical manifestations, histopathological features, diagnosis, treatment and prognosis of Rosai-Dorfman′s disease (RDD) in the maxillofacial region and to review the relevant literature in order to improve the understanding, diagnosis and treatment of oral and maxillofacial RDD.@*Methods @#The clinical manifestations, histopathological features, diagnosis, treatment, and prognosis of a patient with RDD in the maxillofacial region admitted to Shenzhen People′s Hospital were analyzed, and the literature was reviewed for analysis. @*Results@#The clinical manifestations were palpable masses of 3.5 cm × 2.0 cm × 1.0 cm in the right cheek and 3.0 cm × 2.0 cm × 1.0 cm in the right submaxillary area, with clear boundaries, good mobility, medium and hard textures, respectively, no tenderness, smooth surfaces, and no obvious nodules. On contrast-enhanced and plain CT scans of the maxilla and neck, a diffuse soft tissue shadow was seen in the right maxillofacial region with an unclear boundary and uniform density, and the contrast-enhanced scan also showed moderate and uniform enhancement. The primary diagnosis was right maxillofacial lesions. The tumor was resected surgically. The pathological report was right buccal and right submaxillary extranodal RDD. Under light microscopy, nodular lesions in the fibrous fat tissue were found, which were composed of light and deep staining areas. The light staining areas consisted of patchy, polygonal cells with large volumes and rich cytoplasm, in which lymphocytes and neutrophils could be seen stretching into the movement; the deep staining areas were composed of lymphocytes and plasma cells. IHC: S-100 (+), CD68 (+), CD163 (+), CD1a (-), CD21FDC (+), langerin (-), IgG (+), IgG4 (+). No recurrence was found 11 months after the operation. RDD is a rare, benign and self-limited tissue and cell disease and consists of multiple lesions in the maxillofacial region. Its imaging features are similar to those of lymphoma. Its pathological features are large volumes, rich cytoplasm and phagocytosis of lymphocytes and plasma cells. Generally, RDD only needs to be observed, and individuals with symptoms or the involvement of important organs need to be treated; the first choice for the extranodal type is drug treatment, with radiotherapy administered if the central nervous system is involved. Surgery is recommended if involvement of important organs and compression of the trachea are observed; chemotherapy should be used for diffuse RDD. Most patients with RDD experienced relapse or remission of the disease; a few patients died because of the involvement of important organs or complications.@*Conclusion @#The clinical manifestations of maxillofacial RDD vary and lack specific imaging features, and pathological immunohistochemistry is the gold standard for diagnosis. The etiology is not completely clear, the treatment methods are varied, and the prognosis is related to the involved range of the disease.

ABSTRACT

Background/Aim: Percutaneous thermal ablation combined with transarterial chemoembolization (TACE) becomes a treatment option for unresectable hepatocellular carcinoma (HCC). This study aims to investigate the safety and feasibility of percutaneous thermal ablation combined with simultaneous TACE for patients with HCC ≤ 5 cm. Materials and Methods: From June 2010 to February 2017, a total of 280 patients with HCC ≤ 5 cm who underwent percutaneous thermal ablation combined with simultaneous TACE were included in our study. Their clinical data were collected and analyzed. Results: Major complications occurred in five cases (1.8%). The complete necrosis rate was 91.9%. The median overall survival (OS) was 66.5 months (95% confidence interval [CI] = 57.7–75.2). The OS rates in 1-, 3-, 5-, and 7-year were 96.7%, 76.0%, 59.7%, and 31.1%, respectively. Tumor size (hazard ratio = 1.826; 95% CI = 1.131–2.947; P = 0.014) was considered as independent prognostic factors of long-term survival. Conclusion: Percutaneous thermal ablation combined with simultaneous TACE is a safe and effective treatment for HCC ≤ 5 cm.

ABSTRACT

This study compared the diagnostic efficacy of transrectal ultrasound (TRUS)-guided prostate biopsy (TRBx) and transperineal prostate biopsy (TPBx) in patients with suspected prostate cancer (PCa). We enrolled 2962 men who underwent transrectal (n = 1216) or transperineal (n = 1746) systematic 12-core prostate biopsy. Clinical data including age, prostate-specific antigen (PSA) level, and prostate volume (PV) were recorded. To minimize confounding, we performed propensity score-matching analysis. We measured and compared PCa detection rates between TRBx and TPBx, which were stratified by clinical characteristics and Gleason scores. The effects of clinical characteristics on PCa detection rate were assessed by logistic regression. For all patients, TPBx detected a higher proportion of clinically significant PCa (P - 80 years (80.4% vs 56.5%, P = 0.004) and with PSA level 20.1-100.0 ng ml-1 (80.8% vs 69.1%, P = 0.040). In conclusion, TPBx was associated with a higher detection rate of clinically significant PCa than TRBx was; however, because of the high detection rate at certain ages and PSA levels, biopsy approaches should be optimized according to patents' clinical characteristics.

ABSTRACT

BACKGROUND: Recent evidences indicated that some local anaesthetic agents played a role in inhibiting the proliferation of cancer cells; Whether ropivacaine is able to promote apoptosis of hepatocellular carcinoma (HCC) cells is still unclear. The aim of this study was to investigate the effect of ropivacaine on the apoptosis of HCC cells. METHODS: In the present study, we treated the HCC cell lines, Bel7402 and HLE with ropivacaine. MTT, DAPI stain, trypan blue exclusion dye assay, flow cytometry, electron microscopy, computational simulation, laser confocal microscope, Western blotting, and enzyme activity analysis of caspase-3 were applied to detect the growth and apoptosis of HCC cells and to explore the role mechanism of ropivacaine. RESULTS: Ropivacaine was able to inhibit proliferation and promote apoptosis of HCC cells in a dose- and time-dependent manner. Ropivacaine also has a trait to inhibit the migration of HCC cells; ropivacaine damaged the mitochondria of HCC cells. The results also indicated that ropivacaine was able to interact with caspase-3, promote cytoplasmic caspase-3 migration into the nucleus, stimulate cleavage of caspase-3 and PARP-1, caspase-9 proteins, inhibit the expression of Bcl-2, promote expression of Apaf-1 and mitochondria release cytochrome C, and activate the activity of caspase-3. CONCLUSIONS: Ropivacaine has a novel role in promoting apoptosis of HCC cells; The role mechanism of ropivacaine maybe involve in damaging the function of mitochondria and activating the caspase-3 signalling pathway in HCC cells. Our findings provide novel insights into the local anaesthetic agents in the therapy of HCC patients.

ABSTRACT

The standardized resident training is an important step for training high-level professionals in clinical medicine and it is an important part of medical education after graduation. The training of residents' clinical thinking and clinical judgement should be emphasized in all resident training programs. Some resident programs in China still focus on the teaching of important knowledge that are originated from the medical colleges. Therefore,it is urgent for faculty to adopt new teaching methods aiming at the training of clinical thinking and clinical judgement. The paper introduces a mode for teaching clinical thinking and clinical judgement in the resident training programs. The goal is to improve the level of resident physicians in clinical diagnosis and treatment in China.

ABSTRACT

Abstract Purpose: To investigate the effects of baicalin on inflammatory reaction, oxidative stress and protein kinase D1 (PKD1) and nuclear factor-kappa B (NF-κB) protein expressions in severe acute pancreatitis (SAP) rats. Methods: Sixty rats were divided into sham operation, model, and low-, medium- and high-dose baicalin group. SAP model was established in later 4 groups. The later 3 groups were injected with 0.1, 0.2 and 0.4 ml/100 g 5% baicalin injection, respectively. At 12 h, the serum SAP related indexes and inflammatory factors, peripheral blood CD3 and γδT cell percentages, wet/dry ratio and pancreas ascites volume, oxidative stress indexes and PKD1 and NF-κB protein expressions in pancreatic tissue were determined. Results: Compared with model group, in high-dose baicalin group the wet/dry ratio and ascites volume, serum amylase level, phospholipase A2 activity, TNF-α, IL-1 and IL-6 levels, and pancreatic malondialdehyde level and PKD1 and NF-κB protein expression were significantly decreased (P < 0.05), and peripheral blood CD3 and γδT cell percentages and pancreatic superoxide dismutase and glutathione peroxidase levels were significantly increased (P < 0.05). Conclusion: Baicalin can resist the inflammatory reaction and oxidative stress, and down-regulate protein kinase D1 and nuclear factor-kappa B protein expressions, thus exerting the protective effects on severe acute pancreatitis in rats.

ABSTRACT

Objective To explore the relationship between serum uric acid (SUA) level and coronary heart disease(CHD) in male and female patients. Methods A total of 760 hospitalized patients undergoing coronary angiography in our department from June 2013 to June 2017 were enrolled. Gensini score was calculated according to the result of coronary angiography,and SUA was tested.Patients were divided according to SUA quartiles. The relationship between SUA level and the prevalence of CHD in male and female patients was analyzed. Results Among females,there was significant difference in SUA level between patients with and without CHD (t=4.415,P=0.000). Univariate logistic regression analysis showed that SUA level was independently associated with CHD (OR=1.32,95%CI:1.12-1.58,P=0.002). The prevalence of CHD was 31.2%,52.6%,47.4%,and 59.7%,respectively,in four quartile groups (χ=13.652,P=0.003);in addition,female patients displayed significantly higher prevalence of CHD in the quartile 2 (P=0.007),3(P=0.038),and 4(P=0.000) groups than in quartile 1 group. Among female patients with CHD,there were significant differences in number of target vessels (Z=4.627,P=0.008),number of lesion vessels (χ=18.522,P=0.005),and Gensini score (Z=3.683,P=0.029) in four groups. The Gensini scores of coronary artery were significantly higher in the quartile 4 group than in quartile 1 (P=0.012) and 2 (P=0.014) groups. Multiple linear regression analysis showed that there was a dose-response relationship between SUA level and Gensini score (B=1.105,SE=0.365,P=0.003). Among males,however,there was no significant difference in SUA level between patients with and without CHD(t=1.271,P=0.205). The prevalence of CHD in four quartile groups was 77.9%,69.0%,61.7%,and 79.6%,respectively,showing no significant difference(χ=4.514,P=0.211). Conclusion sSUA is an independent risk fact for female CHD patients. High SUA level is correlated with severity of CHD only in women.

ABSTRACT

This paper aimed to investigate the role of Duhuo Jisheng decotion (DHJSD) in delaying human disc degeneration and its possible molecular mechanism. The intervertebral disc specimens were divided into normal and degenerated groups according to Pfirrmann classfication. The expressions of TNF-α, IL-1β, MMP-3 and MMP-13 in intervertebral disc tissue were detected by Western blot and PCR. Then degenerated human primary NPCs were cultured in vitro, the viability of NPCs treated with stromal cell-derived factor-1 (SDF-1,10 μg·L⁻¹)and various concentrations of DHJSD was assessed by the CCK-8 assay, and the appropriate concentration was screened. The experiment was divided into three groups, control group, SDF-1 group and DHJSD plus SDF-1 group. The levels of TNF-α, IL-1β, Agg, coIⅡ, MMP-3 and MMP-13 were detected. The levels of CXCR4, NF-κB major groups P65 phosphorylation (p-P65) and nuclear translocation, after treated with CXCR4 siRNA and NF-κB inhibitor (BAY11-7082) were measured by Western blot and immunofluorescence. At the same time, the expression of cell inflammatory factors and extracellular matrix were also measured. The expressions of TNF-α, IL-1β, MMP-3 and MMP-13 in the degenerated intervertebral disc tissue were significantly increased. In vitro study, the results of CCK-8 indicated that the viability of NPCs was significantly increased when DHJSD concentration was 300 mg·L⁻¹. After the experiment was divided into three groups, compared with SDF-1 group, the expressions of TNF-α, IL-1β, MMP-3 and MMP-13 in DHJSD group were significantly decreased, but the expressions of Agg, coIⅡ were significantly increased. When CXCR4-siRNA was transfected into NPCs, SDF-1 increased expressions of CXCR4 and p-P65 and inhibited nuclear translocation of P65, whose effect was suppressed by CXCR4-siRNA and DHJSD. In addition, when BAY11-7082 was used to treat NPCs, the expression of TNF-α, IL-1β, MMP-3 and MMP-13 were significantly decreased. DHJSD could inhibit the production of inflammatory factors and promote the synthesis of extracellular matrix. The potential mechanism may be related to the SDF-1/CXCR4/NF-κB signaling pathway.

ABSTRACT

Objective To evaluate the effectiveness of perioperative fasting abbreviation in traumatic patients undergoing selective surgeries.Methods The traumatic patients undergoing selective surgeries from November 2016 to January 2017 at our department were selected for this prospective cohort study.They were divided into an intervention group (69 patients) and a control group (121 patients) according to the wards where they stayed.The intervention group was fasted for solids 6 hours prior to surgery and received oral solution with maltodextrin 2 hours prior to surgery.After surgery,they were allowed to drink liquids as soon as they were awakened.Normal food was allowed 2 hours later.The control group was fasted for either liquids or solids the night before surgery.After surgery,the patients who had received brachial plexus block only were allowed liquids with no limitation while the other patients were allowed liquids 6 hours after surgery and then were free for solids and liquids if no discomfort was observed.The time periods for preoperative liquids and solids fasting and for postoperative intake of liquids and solids were recorded and compared between the 2 groups.The perioperative well-beings (including anxiety,thirst,hunger,nausea,fatigue,dizziness,sweating and stomach discomfort) and serum glucose levels were compared between the 2 groups.Adverse reactions were observed.Results The preoperative fasting time for liquids for the intervention group (4.5 ± 2.9 hours) was significantly shorter than that for the control group (14.3 ±3.9 hours) (P < 0.05).The preoperative fasting time for solids for the intervention group (17.6 ± 3.0 hours) were significantly longer than that for the control group (16.1 ±3.8 hours) (P < 0.05).The postoperative fasting time periods for both liquids [1 (0,3) h] and solids [2 (1,4) h] for the intervention group were significantly shorter than those for the control group [6(6,6) h] hours and [6(6,6) h] (P < 0.05).Compared with the control group,the perioperative anxiety,thirst,hunger,nausea,fatigue,dizziness and stomach discomfort were significantly improved in the intervention group (P < 0.05).The average serum glucose level was similar in both groups upon admission (P < 0.05);it was significantly higher in the intervention group immediately before surgery (P < 0.05) but was gradually decreased after surgery until there was no significant difference between the 2 groups (P > 0.05).No major adverse reaction was observed in either group.Conclusion The protocol of perioperative fasting abbreviation may be safe and feasible in traumatic patients for selective surgeries,showing benefits of decreased anxiety,thirst,hunger,nausea,fatigue,dizziness and stomach discomfort.

ABSTRACT

Objective: To analyze the composition and the content of volatile components in Dipsaci Radix and its wine broiled products. Methods: Headspace solid phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry ( GC-MS) was used to analyze the volatile components in Dipsaci Radix and its wine broiled products. The area normalization method was used to calculate the relative content. Results: Totally 31 ingredients were identified, which mainly included phenols, olefins, alcohols and aldehydes. Totally 25 peaks were detected out from the volatile components in Dipsaci Radix, and among them, 22 components were identified, which accounted for 94. 74% of the total volatile components. The content of 5-allylguaiacol was the highest, which accounted for 28. 37% of the total volatile components. Totally 23 peaks were detected out from the volatile components in wine-pro-cessed Dipsaci Radix, and among them, 17 ingredients were identified, which accounted for 85. 92% of the total volatile components. The content of nonanal was the highest, which accounted for 9. 66% of the total volatile components. Conclusion: The composition and the content of volatile components in Dipsaci Radix and its wine broiled products are different. The experiment provides scientific reference for the further research and development of the volatile components in Dipsaci Radix and its wine broiled products.

ABSTRACT

OBJECTIVE: To analyze studies published in journals included in PubMed in terms of randomized controlled trials (RCTs) examining the therapeutic effect of acupuncture for simple obesity, so as to provide a reference for subsequent RCT-related designs and results. METHODS: RCT literature about acupuncture treatment of simple obesity from the PubMed database and from 2000 to 2016 was retrieved by using keywords of "obesity" "fat" "acupuncture" "joint application of acupuncture and herbal medicine" or "auricular point" "electroacupuncture", "acupoint application", or "cupping", followed by screening, extraction and evaluation of the design methodology and outcomes using Consolidated Standards for Reporting of Trials (CONSORT) and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA). RESULTS: Fourteen articles from six countries in Asia examining the therapeutic effect of acupuncture in the treatment of simple obesity mainly by using acupoints of the Stomach Meridian were included. Generally, acupuncture was found to be more effective than sham acupuncture. However, PubMed did not include any RCTs comparing acupuncture with western medicine for weight loss and many problems (as details of needling manipulation, etc.) remained in the the research reports available in the database. CONCLUSION: All the existing RCTs generally affirm the positive efficacy of acupuncture for simple obesity, but high-quality RCTs, particularly those comparing acupuncture with western medicines for weight loss are lacking.

ABSTRACT

Objective To investigate the correlation between CYP2C19 gene polymorphism and elderly cerebral infarction.Methods Two polymorphisms including rs4244285 and rs4986893 of the CYP2C19 gene were detected by gene chip technology in 72 elderly patients with acute cerebral infarction (stroke group) and 77 otherwise healthy controls. The clinical data and the polymorphism distribution of CYP2C19 were compared,and the potential association between genetic polymorphism and cerebral infarction was analyzed by Logistic regression.Results The frequencies of rs4244285 GG (45.83% vs. 63.64%,Χ =4.766,P=0.029) and rs4244285 A allele (34.03% vs. 22.73%,Χ =4.695,P=0.030) were significantly higher in stroke group than in control group. There were no significant differences in the distribution of the alleles of rs4986893 or the rs4244285 GA and AA between these two groups (all P>0.05). After the conventional cerebrovascular risk factors including gender,age,body mass index,smoking,and total cholesterol were adjusted,Logistic regression analysis showed that rs4244285 A allele significantly increased the stroke risk [the additive model AA vs. GG:OR=2.564,95%CI=1.181-5.566,P=0.017;the dominant model AA/AG vs. GG:OR=2.763,95%CI=1.343-5.685,P=0.006].Conclusion CYP2C19 genetic polymorphism may be associated with the increased risk of cerebral infarction in the elderly,although future well-designed studies with larger sample sizes are warranted.
