RESUMEN
Periodontology is one of the important disciplines in oral clinical medicine, which covers a wide range of subjects and intersects with many basic disciplines. Under the environment of the implementation of modular teaching in Shanghai Jiao Tong University School of Medicine, the assessment method with separate propositions for the teaching and research section is still adopted. There is a mismatch between the assessment mode and the curriculum setting; the basic subject propositions are difficult to be combined with clinical cases; the knowledge point assessment is single, and the students' ability to integrate the knowledge points cannot be assessed. The development and construction of the comprehensive examination database for periodontology was based on curriculum integration, gathering the teaching backbones of various disciplines, focusing on periodontology, radiating all related disciplines, unifying the proposition outline, proposition type, proposition principle, combining with relevant knowledge points of various disciplines based on clinical cases, and tried to apply to clinical students majoring in stomatology. The use of the examination database promotes students' ability to flexibly apply theoretical knowledge to clinical case analysis, further promotes the reform of modular teaching, lays a solid foundation for future clinical work, and meanwhile provides an important basis for directions of the teaching and research section.
RESUMEN
Chronic inflammation is critical in the onset and progression of atherosclerosis (AS). The lipopolysaccharide (LPS) level in the circulation system is elevated in AS patients and animal models, which is correlated with the severity of AS. Inspired by the underlying mechanism that LPS could drive the polarization of macrophages toward the M1 phenotype, aggravate inflammation, and ultimately contribute to the exacerbation of AS, LPS in the circulation system was supposed to be the therapeutic target for AS treatment. In the present study, polymyxin (PMB) covalently conjugated to PEGylated liposomes (PLPs) were formulated to adsorb LPS through specific interactions between PMB and LPS. In vitro, the experiments demonstrated that PLPs could adsorb LPS, reduce the polarization of macrophages to M1 phenotype and inhibit the formation of foam cells. In vivo, the study revealed that PLPs treatment reduced the serum levels of LPS and pro-inflammatory cytokines, decreased the proportion of M1-type macrophages in AS plaque, stabilized AS plaque, and downsized the plaque burdens in arteries, which eventually attenuated the progression of AS. Our study highlighted LPS in the circulation system as the therapeutic target for AS and provided an alternative strategy for AS treatment.
RESUMEN
Background and Objectives@#Epithelial-Mesenchymal transition (EMT) is one of the origins of myofibroblasts in renal interstitial fibrosis. Mesenchymal stem cells (MSCs) alleviating EMT has been proved, but the concrete mechanism is unclear. To explore the mechanism, serum-free MSCs conditioned medium (SF-MSCs-CM) was used to treat rat renal tubular epithelial cells (NRK-52E) fibrosis induced by transforming growth factor-β1 (TGF-β1) which ameliorated EMT. @*Methods@#and Results: Galectin-3 knockdown (Gal-3 KD) and overexpression (Gal-3 OE) lentiviral vectors were established and transfected into NRK-52E. NRK-52E fibrosis model was induced by TGF-β1 and treated with the SF-MSCs-CM for 24 h after modelling. Fibrosis and autophagy related indexes were detected by western blot and immunocytochemistry. In model group, the expressions of α-smooth muscle actin (α-SMA), fibronectin (FN), Galectin-3, Snail, Kim-1, and the ratios of P-Akt/Akt, P-GSK3β/GSK3β, P-PI3K/PI3K, P-mTOR/mTOR, TIMP1/MMP9, and LC3B-II/I were obviously increased, and E-Cadherin (E-cad) and P62 decreased significantly compared with control group. SF-MSCs-CM showed an opposite trend after treatment compared with model group. Whether in Gal-3 KD or Gal-3 OE NRK-52E cells, SF-MSCs-CM also showed similar trends. However, the effects of anti-fibrosis and enhanced autophagy in Gal-3 KD cells were more obvious than those in Gal-3 OE cells. @*Conclusions@#SF-MSCs-CM probably alleviated the EMT via inhibiting Galectin-3/Akt/GSK3β/Snail pathway. Meanwhile, Gal-3 KD possibly enhanced autophagy via inhibiting Galectin-3/Akt/mTOR pathway, which synergistically ameliorated renal fibrosis. Targeting galectin-3 may be a potential target for the treatment of renal fibrosis.
RESUMEN
Objective:To observe any effect of supplementing continuous static stretching (CSS) with extracorporeal shock wave therapy (ESWT) in treating triceps surae spasm after a stroke.Methods:Sixty-four stroke survivors with triceps surae spasm were randomly divided into a conventional rehabilitation group, a shock wave group and a combined treatment group. In addition to conventional rehabilitation, the shock wave group received extracorporeal shock wave therapy twice a week and the combined treatment group received the shock waves during continuous static stretching. After 6 weeks of treatment all of the subjects were assessed using the Modified Ashworth Scale (MAS), the Fugl-Meyer Assessment (FMA) and Brunnstrom classification of their functional recovery stage.Results:Before treatment there was no significant difference among the three groups. After the 6 weeks of treatment the average triceps surae tension in all three groups had eased significantly. At that point the average MAS and FMA scores of the shock wave group and the combined treatment group were significantly better than those of the conventional group. The combined treatment group then showed significantly better therapeutic effect than the shock wave group.Conclusions:Applying extracorporeal shock waves during continuous static stretching can significantly improve the stretching′s ability to reduce spasticity and improve motor functioning, at least of the triceps surae. Combining shock waves with modern traction methods is recommended for clinical application.

RESUMEN
Objective@#To study the response characteristics of the posterior intralaminar nucleus (PIN) of auditory thalamus in VGluT2-Cre transgenic adult mice when exposed to white noise and 10K pure tone stimulation.@*Methods@#All adult male Vglut2-Cre mice (8-12 weeks) were used in this study between Oct, 2017 and Oct, 2018. Using the calcium signal fiber photometry method, optic fiber was employed to locate on PIN by injecting AAV-hSyn-DIO-GCaMP6m virus, and thereafter, the activity of the target cluster neurons during different acoustic stimuli was recorded. Matlab was used for data processing and statistical analysis.@*Results@#(1)In both white noise and 10 kHz pure tone as a continuous three-second stimulation, the peak amplitude of calcium signal activity generated in PIN by white noise was superior to that of pure tone, the statistic result showed significantly difference (n=6, t=2.404, P=0.037 1) . (2)In addition, when white noise and 10K pure tone played as consecutive 3 or 5 pips within three-second stimulation, the stimulus-following ability in a consecutive 3 pulses play within 3 seconds was far better than a consecutive 5 pips play within 3 seconds (in both white noise and 10 kHz pure tone), yet consecutive 3 pips play showed greater signal attenuation speed than that in consecutive 5 pips play, the statistic result showed significantly difference (n=6, t=2.748 P=0.033 4) .(3)Regardless of the intra-group comparisons between white noise and 10 kHz pure tone stimulation, PIN showed better signal response in a consecutive 3 pips play than consecutive 5 pips play or a continuous three-second stimulation. When came to the statistical analysis, the acoustic response degree of a continuous three-second stimulation was an intermediate between two others, both consecutive 3 or 5 pips play showed significantly difference.@*Conclusions@#The results suggest that under the same acoustic intensity, VGluT2-Cre transgenic adult mice′s PIN shows greater signal response in white noise than pure tone. PIN shows greater signal attenuation to repetition play of 10 kHz pure tone, which implies PIN shows stronger adaptation to 10 kHz pure tone than to white noise. Lastly, PIN is more responsive to a complex sound information (white noise) than to simple sound information (pure tone).

Objective To establish and evaluate a rat model of nonarteritic anterior ischemic optic neuropathy (NAION).Methods The rats were randomly divided into control group (n=13), sham laser group (n=11) and NAION group (n=23). The right eye was set as the experimental eye. NAION model was induced by directly illuminating the optic nerve (ON) of the right eye with 532 nm green laser, after intravenous infusion with the photosensitizing agent Rose Bengal. Sham laser treatment consisted of illuminating the ON region with 532 nm laser without Rose Bengal injection. Rats in control group underwent no intervention. The appearance of optic disc was observed with funduscope at 12 hours, 1, 3, 7, 28 days post-illumination. The histologic changes in the retina and ON of the NAION model were evaluated qualitatively with hematoxylin and eosin (HE) staining and transmission electron microscopy. The retrograde-labeled retinal ganglion cells (RGC) were counted on photographs taken from retinal flat mounts in a masked fashion.Results The optic disc in NAION eyes were swollen 3 days after photodynamic treatment. HE-stained longitudinal ON sections of NAION revealed vacuolar degeneration on day 3 after induction. Besides, ultrastructural study showed axonal edema and collapsed sheaths in the ischemic optic nerve at the same time point after modeling. ON edema resolved 7 days after induction. The final results revealed optic disc atrophy, extensive axonal loss, severe glial scar, and RGC death in large numbers 4 weeks after modeling. There were no aforementioned manifestations in control and sham laser group. The RGC density of the right eyes was statistically significantly lower in NAION group than that in control group and in sham laser group (t=?14.142, ?14.088;P=0.000, 0.000). The survival rate of RGC was statistically significantly lower in NAION group than in control group and in sham laser group (t=?17.048, ?16.667;P=0.000, 0.000). There was no difference of RGC density and survival rate of RGC between control and sham laser group (t=0.050, 0.348;P=0.961, 0.731).Conclusion A rat model of NAION was established successfully by photodynamic treatments with Rose Bengal, which induce optic nerve damage and RGC death.
RESUMEN
Objective · To investigate the clinical effects of photo-activated disinfection (PAD)-assisted non-surgical therapy on the treatment of chronic periodontitis. Methods · Eleven patients with chronic periodontitis (totally 118 selected sites) were randomly enrolled. A split-mouth self-control method was adopted. Selected sites with the probing depth (PD) of bilateral homonymous teeth ≥ 5 mm were randomly assigned to the group A (receiving scaling and root planning, SRP) and the group B (receiving SRP+ PAD). Periodontal clinical indexes, inflammation indexes, and periodontal pathogens at selected sites were examined at baseline and 6 and 12 weeks after treatment. Results · Both SRP alone and SRP+PAD improved the periodontal inflammation significantly. The positive rate of bleeding on probing (BOP) 12 weeks after treatment was remarkably lower in the group B than in the group A (37.3% vs 57.6%, P=0.042). Both SRP and SRP+PAD effectively decreased matrix metalloproteinase-8 (MMP-8) and interleukin-1β (IL-1β) levels in gingival crevicular fluid. The IL-1β levels 6 and 12 weeks after treatment were significantly lower in the group B than in the group A [(17.99±14.26) pg/mL vs (32.64±30.69) pg/mL, P=0.007; (11.37±10.25) pg/mL vs (23.85±15.55) pg/mL, P=0.000]. Both treatments decreased the ratio of P. gingivalis and F.nucleatum in total bacteria. Conclusion · PAD can serve as a potential adjunctive therapy to conventional SRP in the treatment of chronic periodontitis with better improvement of bleeding gums and control of periodontal inflammation.

Objective · To observe short and medium term survival of implants in patients with chronic periodontitis after implantation. Methods · 54 patients with chronic periodontitis (133 implants) were enrolled from August 2011 to August 2013. The survival of implants was observed and the periimplant diseases were compared and analyzed between patients with different degrees of chronic periodontitis. Results · The 3-year survival rate of implants was 97.74%. The differences between patients with different degrees of chronic periodontitis were not statistically significant (P=0.452). Periodontal pocket depth (PPD) and modified plaque index (mPLI) were significantly higher in patients with severe chronic periodontitis than in patients with mild and moderate chronic periodontitis. For patients not receiving supportive periodontal therapy (SPT), the peri-implantitis rate in patients with severe chronic periodontitis was significantly higher than that in patients with mild and moderate chronic periodontitis (P=0.009). For smokers, the periimplantitis rate in patients with severe chronic periodontitis was significantly higher than that in patients with mild and moderate chronic periodontitis (P=0.016). Conclusion · For patients with chronic periodontitis, the theraputic effect of implant treatment is good. Plaque control, SPT, and smoking cessation can reduce the incidence of peri-implantitis.
RESUMEN
Objective·To isolate lipopolysaccharide (LPS) and capsular polysaccharide (CPS) from Porphyromonas gingivalis (Pg) and analyze their ability to induce THP-1 cells to secrete interleukin 8 (IL-8) in vitro. Methods·LPS and CPS were isolated from the polysaccharides by gel filtration chromatography, which had already been extracted from Pg ATCC33277 and SJD4. The isolated LPS and CPS from different strains were used to stimulate THP-1 cells in different doses and for different periods. The level of IL-8 in the cell culture suspension was measured by ELISA. Results·LPS and CPS were successfully separated from the polysaccharides in Pg ATCC33277 and SJD4. The relative molecular masses of LPS and CPS were 20000-50000 and 150000-500000, respectively. LPS and CPS could induce THP-1 cells to produce IL-8 in vitro in a time- and dose-dependent manner. The effect of LPS from ATCC33277 on secretion of IL-8 was greater than that of CPS with the dose of 0.1 μg/mL (P<0.05). However, the difference could only be found at 24 h in SJD4, and the effect of CPS was greater (P<0.05). Conclusion·As a component of polysaccharides extracted from Pg, CPS can induce THP-1 cells to secrete IL-8 in vitro in a time- and dose-dependent manner.

RESUMEN
The quality control processes for herbal medicines have been problematic. Flavonoids are the major active components of Huangqin Tang (HQT, a traditional Chinese medicine formula). In this study, we used a combinative method approach consisting of chromatographic fingerprinting (high performance liquid chromatography; HPLC), quantitative methods and a pharmacodynamic evaluation model to analyze the flavonoids of HQT obtained from different sources. Ten batches of HQT were analyzed by the HPLC fingerprinting method and 26 common peaks were detected, of which 23 peaks corresponded with the chemical profile of HQT. In addition, 11 major compounds were identified by LC-MS analysis (liquid chromatography-tandem mass spectrometer; LC-MS (n) ) and quantified by the HPLC quantitative method approach. The studied 10 batches of HQT were found to be homogeneous in their composition with a similarity between 0.990 and 1.000. The distribution of the 11 identified compounds was found to be very similar among the batches. Only slight pharmacodynamic differences were detected between the different batches, confirming the homogeneity of HQT. The results of this study prove that the combination of chromatographic fingerprinting and quantitative analysis can be readily used for comprehensive quality control of herbal medicines.
RESUMEN
Objective Controversies remain as to the recovery time, recovery quality, and incidence of peri-recovery adverse reactions of the patient receiving general anesthesia with remifentanil and sufentanil.This study aimed to systematically assess the qual-ity of recovery from general anesthesia with remifentanil and sufentanil. Methods Randomized controlled trials ( RCTs) were re-trieved from The Cochrane Library, PubMed, MEDLINE, EMbase, Ovid, Springer, Web of Science, CNKI, CBM, VIP, and Wan-Fang Data.According to the modified Jadad quality scale, the literature retrieved was screened and subjected to quality evaluation and meta-analysis was performed on the included studies using the RevMan 5.1 software. Results Thirty-three RCTs involving 2175 pa-tients were finally included.The results of meta-analysis showed no significant differences between the remifentanil and sufentanil groups undergoing thyroid surgery either in the recovery time to spontaneous breathing ( T1) and eye-opening ( T2) and endortracheal extubation time ( T3 ) ( P >0.05 ) or in the incidence rate of postoperative nausea and vomiting (PONV) (P>0.05).T1, T2 and T3 were significantly shorter in the sufentanil than in the remifentanil group in other types of surgery (P<0.05).The patients with level-1 Ramsay score were remarkably more in the remifentanil than in the sufentanil group ( MD =13.67, 95% CI 2.67 -69.91 ) ( P <0.05), and the VAS scores were markedly higher in the former than in the latter group at 30 minutes (MD=3.37, 95% CI 3.28-3.46) and 1 hour after extubation (MD=2.53, 95% CI 2.43 -2.63) (P<0.05). Conclusion Compared with sufentanil, remifentanil provides a quicker recovery but a weaker analgesia effect and a higher rate of post-operative agitation.However, sufentanil produces a better pain relief and a higher quality of recovery after operation.

RESUMEN
Objective To study the relationship between IGF-1, IGFBP-3 and prostatic volume (PV) by examining the levels of insulin and insulin-like growth fator-1 (IGF-1) and insulin-like growth factor binding protein-3 ( IGFBP-3 ) and other indicators in patients with impaired glucose regulation and benign prostate hypertrophy. Methods According to 75 g oral glucose tolerance test (OGTT) results, 109 BPH patients aged over 50 years were divided into three groups: normal glucose tolerance (NGT) group (n = 56), impaired fasting glucose (IFG) group (n = 14), impaired glucose tolerance (IGT group, n = 39). The biochemical indicators and postatic hyperplasia related factors and IGF-1, GFBP-3 were measured. Results There were no statistical differences between the three groups in terms of blood lipids, homocysteine, urinary inhibition C, fasting insulin (FINS), glycosylated hemoglobin, IGF-1 and IGFBP-3 (P > 0.05). There were no significant differences between the groups in terms of PV, prostate specific antigen, the quality of life score and the international prostate symptom score (P > 0.05). Fasting plasma glucose and insulin resistance index (HOMA IR) were higher in IFG group than NGT group (P′ < 0.017) and IGT group (P′ < 0.017). 2-hour plasma glucose and 2-hour insulin were higher in IGT group than NGT group (P′ < 0.017) and IFG group (P′ < 0.017). PV was positively correlated with FINS but not correlated with IGF-1, IGFBP- 3 by multiple multiple step wise regression analysis. Conclusion Oyperinsulinemia is a risk factor in the development of BPH with IGR, and IGF-1 and IGFBP-3 are not associated with BPH risk. Further investigation is needed to elucidate the role of the IGF-1 and IGFBP-3 in BPH.
