ABSTRACT

@#All-ceramic restorations are widely used in oral restoration because of their beauty and high strength. Glass ceramics and zirconia all-ceramic materials are the two most widely used all-ceramic materials in the clinic. However, when all-ceramic restorations need to be removed due to marginal microleakage and secondary caries, its high strength and high bonding strength greatly increase the difficulty of removal. In recent years, clinicians have tried to use Er: YAG lasers to remove all-ceramic restorations. The Er: YAG laser can be safely and efficiently applied to the removal of glass restorations, and it can also play a role in thinner zirconia restorations. Various factors, such as the material and thickness of the all-ceramic restoration, the type of cement, and the laser power, can affect the speed of removal of the Er: YAG laser. However, the current research is limited to case reports and in vitro studies, lacking systematic clinical research. The specific mechanism of Er: YAG laser removal of all-ceramic restorations and the influence of laser frequency, adhesive type, and abutment on the removal speed need to be further demonstrated by follow-up research.

ABSTRACT

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a rare adverse cutaneous reaction with a low incidence and high mortality. Despite posing a serious threat to patients' health and lives, there is no high-quality evidence for a standard treatment regimen. Here we report the case of a 62-year-old man with stage IV pancreatic cancer who experienced immunotherapy-induced SJS/TEN. After consensus-based regular treatments at a local hospital, his symptoms became worse. Thus, he consented to receive Chinese herbal medicine (CHM) therapy. The affected parts of the patient were treated with the CHM Pi-Yan-Ning which was applied externally for 20 min twice a day. After 7 days of treatment, the dead skin began peeling away from the former lesions that had covered his hands, feet, and lips, indicating that skin had regenerated. After 12 days of treatment, the patient's skin was completely recovered. In this case, SJS/TEN was successfully treated with Pi-Yan-Ning, suggesting that there might be tremendous potential for the use of Pi-Yan-Ning in the treatment of severe skin reactions to drug treatments. Further basic investigations and clinical trials to explore the mechanism and efficacy are needed.

ABSTRACT

Coronary microembolization (CME) is associated with cardiomyocyte apoptosis and cardiac dysfunction. Puerarin confers protection against multiple cardiovascular diseases, but its effects and specific mechanisms on CME are not fully known. Hence, our study investigated whether puerarin pretreatment could alleviate cardiomyocyte apoptosis and improve cardiac function following CME. The molecular mechanism associated was also explored. A total of 48 Sprague-Dawley rats were randomly divided into CME, CME + Puerarin (CME + Pue), sham, and sham + Puerarin (sham + Pue) groups (with 12 rats per group). A CME model was established in CME and CME + Pue groups by injecting 42 μm microspheres into the left ventricle of rats. Rats in the CME + Pue and sham + Pue groups were intraperitoneally injected with puerarin at 120 mg/kg daily for 7 days before operation. Cardiac function, myocardial histopathology, and cardiomyocyte apoptosis index were determined via cardiac ultrasound, hematoxylin-eosin (H&E) and hematoxylin-basic fuchsin-picric acid (HBFP) stainings, and TdT-mediated dUTP nick-end labeling (TUNEL) staining, respectively. Western blotting was used to measure protein expression related to the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/glycogen synthase kinase-3β (GSK-3β) pathway. We found that, puerarin significantly ameliorated cardiac dysfunction after CME, attenuated myocardial infarct size, and reduced myocardial apoptotic index. Besides, puerarin inhibited cardiomyocyte apoptosis, as revealed by decreased Bax and cleaved caspase-3, and up-regulated Bcl-2 and PI3K/Akt/GSK-3β pathway related proteins. Collectively, puerarin can inhibit cardiomyocyte apoptosis and thus attenuate myocardial injury caused by CME. Mechanistically, these effects may be achieved through activation of the PI3K/Akt/GSK-3β pathway.

ABSTRACT

Objective@# To explore the clinical effect of a guided resin cementation technique on vertical food impaction symptoms and to provide a new method for the treatment of vertical food impaction. @* Methods @#Treatment of 76 patients with vertical food impaction with guided resin cementation was performed. A specially fabricated contact shaping wire was used to aid the shaping of the contact. Cementation was applied under a rubber dam with the total-etch technique with flowable composite resin. Patient subjective perception was recorded after treatment (i.e., “totally relieved”=3, “significantly improved”=2, “slightly improved”=1 and “no change”=0). Follow-up visits lasted for one year. Scores of 1 to 3 were recorded as effective. The efficiency rates at different times were calculated. @*Results@#Patient subjective perceptions scored 2.47, 2.21, 1.79, 1.30 and 0.97 on the day immediately after and 1, 3, 6, and 12 months after treatment, respectively. There were significant differences among scores at each time point (P<0.01). The Efficacy rate reached 91.78% immediately after treatment and was sustained above 50% within half a year. Management of resin debonding or fracture successfully relieved the symptoms again.@*Conclusion@#The guided resin cementation technique relieves vertical food impaction symptoms immediately, and the effect of the guided resin cementation technique is maintained for a short period of time. Management of resin debonding or fracture helps consolidate treatment outcomes.

ABSTRACT

Objective To analyze the epidemiological characteristics of food poisoning in Shenzhen from 2009 to 2018, and to provide a scientific basis for formulating control strategies of food poisoning. Methods The data of food poisoning events in Shenzhen from 2009 to 2018 was analyzed with descriptive epidemiological methods. Results There were 182 reported food poisoning events, resulting in 1786 cases and 3 death. The incidence of food poisoning events had a seasonal peak during May to September, and a total of 119 reported food poisoning events (65.39%, 119/182) occurred in that period of time with 1156 cases (64.73%, 1156/1786). There were 77 food poisoning events (42.31%) occurring in collective canteens with 927 cases (51.91%), making them the most frequent locations for food poisoning. The main pathogenic factors were bacteria, poisonous plants and chemicals. Incidents of bacterial food poisoning were mainly caused by Vibro parahemolyticus (51.73%, 60/116), Salmonella (26.73%, 30/116), and Staphylococcus aureus enterotoxin (11.21%, 13/116), etc. Hyacinth bean toxin and mushroom were responsible for 33.33% of the incidents caused by poisonous plants. Incidents of chemical food poisoning were mainly caused by nitrite (8.33%). Conclusion The prevention and control of food poisoning in Shenzhen should be focused on reducing bacterial food poisoning such as Salmonella and Vibrio parahaemolyticus, and supervision of food safety of catering units and collective canteens should be strengthened. Additionally, health education on prevention and control of food poisoning should be targeted at the high-risk population to reduce the risk of food poisoning.

ABSTRACT

OBJECTIVE@#To observe the auxiliary analgesic effect of wrist-ankle acupuncture on patients undergoing transforaminal endoscope surgery.@*METHODS@#A total of 64 patients with lumbar disc herniation who underwent percutaneous lateral transforaminal endoscope surgery were randomly divided into an observation group and a control group, 32 cases in each group. The patients in the control group were treated with injection of 1% lidocaine for routine local infiltration anesthesia. The patients in the observation group were treated with wrist-ankle acupuncture at lower 5 area and lower 6 area for 30 min, 5 min before routine local infiltration anesthesia; immediately, 15 min, 30 min after insertion the left-right technique, up-down technique, and rotation technique were applied for six times, respectively. The mean arterial pressure (MAP), heart rate (HR), blood oxygen saturation (SpO) and pain visual analogue scale (VAS) were compared between the two groups at the time points of intraoperative puncture (T), circular saw grinding (T), and placement of working channel (T). The intention of reoperation was recorded immediately after operation and 24 h after operation. The expectation and treatment credibility scale (ETCS) was used to evaluate the relationship between patients' expectation and efficacy 5 min before operation and immediately after operation.@*RESULTS@#At T and T during the operation, the MAP and HR in the obserrvation group were lower than those in the control group, while SpO was higher than that in the control group (0.05). At T, the peak VAS and average VAS in the observation group were lower than those in the control group (0.05). The intention of reoperation in the observation group was higher than that in the control group both immediately after operation and 24 h after operation (0.05). The scores of ETCS1, ETCS2 and ETCS3 immediately after operation in the observation group were higher than those in the control group (<0.05).@*CONCLUSION@#The wrist-ankle acupuncture has positive auxiliary analgesic effect on lumbago during transforaminal endoscope surgery, and strengthens the patients' confidence on the operation effect.

ABSTRACT

Objective@#To compare the pathogenicity of isolates of sequence type 7 (ST-7) ( ) belonging to four different serogroups (A, B, C, and X).@*Methods@#Four ST-7 isolates serogrouped as A, B, C, and X and characterized by different capsule structures, were examined for their adhesion and invasion properties, and their ability to induce cytokine release and apoptosis in the host cell (the A549 cell line).@*Results@#Among the four ST-7 isolates, the serogroup A isolate possessed the strongest adhesion and invasion ability. This isolate also induced the release of the highest levels of the pro-inflammatory mediators interleukin-6, interleukin-1β, and interferon, and the highest apoptosis rate in the host cells. However, there was no significant difference in interleukin-8 and tumor necrosis factor-α secretion between the four isolates. Based on the findings, the serogroup X isolate had the weakest pathogenicity, whereas there was almost no difference in the pathogenicity of the isolates from serogroups B and C.@*Conclusions@#The differences in the capsular structure of the four isolates of ST-7 affected their pathogenic capacities. The findings also imply that the hyperinvasive ST-7 lineage may include hypoinvasive isolates.

ABSTRACT

OBJECTIVE@#To systematically assess the efficacy of anterior cervical corpectomy and fusion (ACCF) versus posterior laminoplasty (LAMP) for cervical ossification of posterior longitudinal ligament (OPLL).@*METHODS@#PubMed and EMBASE, Cochrane Library, CBM, CNKI, Wanfang and VIP were collected from 7 databases of ACCF, LAMP from 1970 to May 2018. According to the criteria, the articles were included and independently screened by two authors. The quality of the articles was assessed by using the MINORS scale (methodological index for non randomized studies). After extracting the data from the article, the JOA score, cervical curvature, operation time, bleeding volume, excellent and good rate, recovery rate, adverse events and secondary surgery were analyzed by using Review Manager 5.3 software.@*RESULTS@#Finally, a total of 22 articles with 1 678 patients were included in this Meta-analysis, with 810 patients in ACCF group and 868 patients in LAMP group. Meta analysis results showed that the ACCF group had higher postoperative JOA scores[MD=0.63, 95%CI(0.05, 1.20), = 0.03], higher excellent rate [=1.85, 95%CI (1.14, 3.02), =0.01] and higher recovery rate [=11.90, 95%CI (5.75, 18.05), =0.000 1]. But the LAMP group has a shorter operative time [MD=52.19, 95%CI (29.36, 75.03), <0.000 01], less complications [=1.56, 95%CI (1.03, 2.35), =0.04] and less reoperations [=3.73, 95%CI (1.62, 8.57), =0.002]. There was no significant different in postoperative lordosis [MD=3.15, 95%CI(-0.14, 6.43), =0.06] and blood loss[SMD= 0.26, 95%CI(-0.05, 0.57), =0.10] between two groups.@*CONCLUSION@#The recovery of functionof ACCF group was better, but operation time, complications and reoperations of LAMP group were all better than ACCF group. There was no difference in postoperative lordosis and intraoperative blood loss between two groups. However, there are some limitations in this study. Therefore, higher quality and larger sample size clinical studies are needed to further verify.

ABSTRACT

Objective:To study the regulatory effect and mechanism of MDM2/p53 pathway on apoptosis in multiple myeloma (MM). Methods: RPMI8226 cells were cultured in vitro and divided into Nutlin-3a group, control group and blank group. CCK-8 method was used to detect the cell inhibition rate, Western blot was used to detect the expression of apoptosis-related protein, and flow cytometry was used to detect the apoptosis in the two groups. Results: Compared with that in control group, the inhibition rate of cells in the experimental group increased significantly at 24 h, 48 h and 72 h (P<0.05). Compared with those in the control group, the expression levels of MDM2 and Bcl-2 in the experimental group decreased significantly (P<0.05), while the expression level of p53 increased significantly (P<0.05). The apoptosis rate was significantly higher in the experimental group than in the control group at 24 h, 48 h and 72 h (38.42%, 82.26% and 82.74% vs. 4.80%, 8.06% and 14.69%). Conclusion: The degradation trans-activation pathway between MDM2 and p53 affects the expression of Bcl-2, inhibits the proliferation of MM cells, and promotes the apoptosis of MM cells.

ABSTRACT

Objective@#To investigate the effects of 12-week high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on body composition, arterial stiffness(cfPWV) and serum resistin level in the obese college female students, so as to provide a theoretical reference for improving the cardiovascular health of obese college students and seeking better ways of losing weight.@*Methods@#Thirty-seven female college students were chosen and then randomly assigned to HIIT group(n=19), MICT group(n=18). The subjects in both the HIIT group and MICT group underwent exercise for 12 weeks(five times per week). Then body composition and resistin level were measured, arterial stiffness by carotid-femoral pulse wave velocity (cfPWV) was evaluated in all subjects before and after training.@*Results@#After 12-week exercise, body weight, BMI, body fat and trunk fat significantly decreased in both HIIT and MICT groups (t=2.19, 6.02, 2.64, -2.76, P<0.05); muscle mass significantly increased, serum resistin level and cfPWV significantly decreased (P<0.01) only in HIIT group. Compared with the MICT group, trunk fat, cfPWV, serum resistin level were lower and muscle mass was higer in HIIT group(P<0.05), while the reduction of serum resistin level before and after the intervention of HIIT was positively correlated with the reduction in the trunk fat and cfPWV, and negatively correlated with the increases in the muscle mass(r=0.52, 0.56, -0.65, P<0.01).@*Conclusion@#Both HIIT and MICT have favorable effects on body composition in obese college female students. However, HIIT is more beneficial for improving the trunk fat and arterial stiffness than MICT group which may be associated with decreases in serum resistin level.

ABSTRACT

@#【Objective】To explore the effects of overexpressed senescence marker protein 30 (SMP30) on cell proliferation and antioxidative activity in human lens epithelial cell(HLEC)line SRA01/04 under high-calcium mediated oxidative stress. 【Methods】There were 3 groups in this experiment:SMP30 overexpressed group (OE,experimental group),NCOE group (negative control group) and SRA01/04 group (blank control group). OE and NCOE lentiviral vectors were used to transfect SRA01/04 respectively. A high- calcium- mediated- stress cell model was established by culturing cells with medium containing 15 mmol/L CaCl2 for 24 h. BrdU assay was used to measure cell proliferation. SOD assay kit and GSSG/T- GSH assay kit were used to detect the level of intracellular oxidative stress. 【Results】Green fluorescence protein could be observed in all transfected cell groups under fluorescence microscope and the transfection efficiency was close to 80% ,suggesting that OE cell model was constructed successfully. Under the high calcium culture conditions,the activity of relative cell proliferation and SOD in OE group[(3.89 ± 0.20)and(47.5 ± 4.3 U/mg)]were significantly higher than that in NCOE group[(2.82 ± 0.34)and(30.6 ± 4.2 U/mg)]and SRA01/04 group[(2.96 ± 0.25)and(26.8 ± 1.5 U/mg)],the ratio of GSSG/T-GSH in OE group(2.36 ± 0.51)was significantly lower than that in NCOE group(16.36 ± 2.48)and SRA01/04 group(20.12 ± 2.54)(n=3,P<0.05);there was no significant difference between NCOE group and SRA01/04 group (n=3,P>0.05). 【Conclusions】Overexpression of SMP30 increased the activity of cell proliferation and SOD,but decreased the ratio of GSSG/T- GSH in SRA01/04 cell(HLEC),indicating that SMP30 may alleviate the progression of high-calcium-mediated oxidative cell damage and possess the cytoprotective functions in HLEC.

In order to clarify the role of pyroptosis in H/R-injury, H9c2 cells were divided into 4 groups randomly using the lottery method: control group(in which the H9c2 cells were cultivated with normal medium); YVAD group(in which the H9c2 cells were pretreated with z-Val-Ala-Asp(Ome)-fluoromethylketone (Z-YVAD-FMK) 20 μm for 4 hours, then replaced with normal medium); H/R group(H9c2 cells underwent H/R-treatment); YVAD+H/R group (in which the H9c2 cells were pretreated with 20 μm Z-YVAD-FMK for 4 hours before H/R-treatment). To determine whether H/R-induced cell pyroptosis is associated with NLRP3, H9c2 cells were divided into 4 groups randomly using the lottery method: control group (in which cells were transfected with a control nonspecific siRNA); si-NLRP3 group (in which cells were transfected with NLRP3-targeting siRNA); H/R group(in which cells were transfected with a control nonspecific siRNA before H/R-treatment); si-NLRP3+H/R group(in which the H9c2 cells were transfected with NLRP3-targeting siRNA before H/R-treatment). Pore formation on cell membrane was detected by propidium iodide (PI) staining. Cell viability was detected by CCK8 reagent. The protein expression of Caspase-1, interleukin-1β (IL-1β) and NLRP3 was detected by Western blot.@*Results@#(1) The positive rate of PI staining ((26.46±5.15)% vs. (1.69±0.73)%,P<0.01), expression of NLRP3 (0.57±0.16 vs. 0.23±0.06,P<0.01), expression of Caspase-1 (1.07±0.13 vs. 0.37±0.08,P<0.01), and expression of IL-1β (0.38±0.08 vs. 0.16±0.05,P<0.01) were significantly higher in H/R group than in control group. (2)The cell vitality was significantly higher in YVAD+H/R group than in H/R group ((87.31±9.05)% vs. (73.30±7.19)%, P<0.05).The positive rate of PI staining was significantly decreased in YVAD+H/R group than in H/R group ((18.12±4.36)% vs. (26.45±4.60)%, P<0.05). The expression of Caspase-1 (0.72±0.12 vs. 1.07±0.15, P<0.05) and IL-1β(0.29±0.07 vs. 0.39±0.06, P<0.05) were significantly lower in YVAD+H/R group than in H/R group. (3) The cell vitality was significantly increased in si-NLRP3+H/R group than in H/R group ((85.46±7.71)% vs. (72.41±5.53)%, P<0.05). The positive rate of PI staining was significantly lower in si-NLRP3+H/R group than in H/R group ((18.22±4.20)% vs. (26.73±3.26)%, P<0.05). The expression of Caspase-1(0.87±0.07 vs. 1.15±0.15, P<0.05) and IL-1β(0.41±0.07 vs. 0.58±0.10, P<0.05) were significantly decreased in si-NLRP3+H/R group than in H/R group.@*Conclusion@#NLRP3 mediated pyroptosis is involved in H/R injury of myocardial cells.

ABSTRACT

In clinical practice, professor integrates the guiding- acupuncture technique of slow insertion and withdrawal of the needle with the thought of needling sensation reaching the affected site. These two theories were recorded in (Chapter 34 of ). Professor proposes that in acupuncture, both acupuncture physician and patient should be in a tranquilizing state. Firstly, the needle is inserted slowly so as to conduct the reversed turbid in back to . After arrival of , with the compound manipulation for promoting , is guided to the affected site. When the treatment ends, the needle is removed slowly to guide the reversed clear in back to and to guide of nutrient and defensive systems back to the original layers. Such acupuncture technique is applicable for various disorders induced by the impairment of activity. In clinical practice, it is adopted for the disorders of heart, lung, stomach, intestines, emotions and nervous system, as well as the obstruction disorders of meridians. The -spring and -stream points of the affected meridians are selected as the main acupoints in prescription. According the theory of four seas and street, the corresponding the front-, back- and -sea points are combined. In acupuncture, the needle is inserted and withdrawn slowly. After arrival of , the needle is manipulated to guide to the pathogenic locations.

ABSTRACT

Congenital infiltrating lipomatosis of the face is a rare disorder resulting from overgrowth of adipose tissues. This condition presents gradually with swelling along with age, hypertrophy of adjacent bones, and tooth abnormalities. This study reports a case of congenital infiltrating lipomatosis of face with seizures and reviews relevant literature on the etiology, clinical symptom, diagnosis, and treatment of this condition.

ABSTRACT

OBJECTIVE@#This study aimed to construct a network of programmed celldeath ligand 1 (PD-L1) co-expression genes and screen potential biomarkers for PD-L1 expression in head and neck squamous cell carcinoma (HNSCC) by bioinformatics analysis. Moreover, the genes and pathways participating in PD-L1 and regulating the tumor immune status were determined.@*METHODS@#The HNSCC transcriptomic dataset in TCGA was selected to retrieve gene sets on the cBioPortal platform, where PD-L1 co-expressional genes were acquired. With these genes, GO-BP, KEGG, and string analyses were performed in R clusterProfiler. Cytoscape was used for network analysis and hub gene screening.@*RESULTS@#A total of 117 co-expression genes were obtained, most of which were enriched in immune regulation and response to viral processes. Node degree analysis indicated that STAT1, IFNG, CXCL10, CCR5, FCGR3A, CXCL9, GBP5, CD86, GZMB, IRF1 were the highest connected genes and functioned as hub genes. Survival analysis of these hub genes resulted in CCR5, CXCL9, and GZMB as the prognostic biomarkers for patients with HNSCC, all of which were involved in immune regulation and their expression levels were related to PD-L1 (Pearson correlation coefficient was 0.30, 0.35, 0.39; P<0.01). High expression levels of these three hub genes were protective factors in patients with HNSCC.@*CONCLUSIONS@#PD-L1 co-expression hub genes are related to immunity, among which CCR5, CXCL9, and GZMB are prognostic markers with the possibility to be involved in programmed cell death protein 1 (PD-1)/PD-L1-induced tumor immune escape. These genes provide new clues to study the mechanism and precision target medicine of PD-1/PD-L1 in HNSCC.
